Mechatronic Support and Application Sup-port, service and technical support world-wide and total equipping of machines andplants (see page 31). To cope with currentand future challenges, and to open up newmarkets for example in Asia and in China

especially, textile machine manufacturersand users find a strong and experiencedpartner in Siemens who has the expertisefor individual solutions and a global salesand service network. �

Fierce competition and an enormous cost pressure in the textile industry ask for an immense effort from machine manufactures for the textile industry. Thosemanufacturers will be successful who offer the required technological quality ofmachines and plants while at the same time as meeting the end customers’ demandsfor high productivity, low “Total Costs of Ownership” and investment security. Here,the automation supplier is doubly challenged. He must support both machine andtextile manufacturers with high performance products and solutions adapted tobranch requirements as well as reliable services.

Partnership with Siemens secures the future

Solutions for your Global Success

Uniform solutions for the manufac-turing process can help to reduce thetime to market, further improve the

transparency of the product quality, reducethe variety of types and parts, optimizemaintenance measures or minimize train-ing times and costs for the machine opera-tors and are consequently in increasingdemand.

Consistently modular

There is therefore a trend towards modularmachines and plants. They can contributeto a shorter project duration and higherengineering quality by using proven hard-ware and software modules. Here, distrib-uted and intelligent drive components suchas Sinamics are at the forefront and, in con-junction with tried and tested controllersand motion control systems, enable inte-grated concepts that guarantee the neces-sary flexibility in concept construction andindividual combination of the mechanicalmachine components.

In addition, Siemens pursues the devel-opment of torque motors, solutions fortransparent production by ManufacturingExecution Systems (MES) and Profinet as afuture communication standard in the tex-tile industry too. Here, Profinet is becomingincreasingly recognized as an industriallycompatible standard which breaks downthe previously existing barriers betweenthe office environment and the automa-tion level.

Everything from one source

As a reliable, long-term partner to the tex-tile industry, Siemens now offers inte-grated automation and drive solutions forthe whole textile manufacturing process.

From man made production to finishing. Inthis way, Siemens supports machine man-ufacturer as a one-stop supplier and there-fore follows another industry trend: “Every-thing from one source” – that is the approachthat end customers use to achieve hori-zontal and vertical integration in their pro-duction.

The portfolio is complemented by reli-able services tailor-made for customers:

Automation has a long tradition intextile production. But what roledoes innovative automation anddrive technology play in today'stextile industry. We asked ProfessorThomas Gries, Head of the Institutefor Textile Technology at theTechnical University of Aachen.

when high flexibility is required. However,a central drive is still best when a machineis running continuously and produces thesame product.

What demands are made on automationand drive technology in the textileindustry?

Thomas Gries: Here too, you have to dis-tinguish between very flexible and moreor less continuous productions of course.Important for the automation and drivetechnology is that it is “just good enough”.In order to be a good judge for this, au-tomation manufacturers, machine man-ufacturers and end users must move clos-er together. That also means a more in-tensive cooperation between the facultiesof mechanical engineering, textile tech-nology and electrical engineering or in-formation technology. To come back to therequirements, it can generally be said thathomogeneity and communication betweenthe individual automation users is becom-ing increasingly important. There is a lotof potential for rationalization here. Justas important is the traceability, especiallyin fiber-reinforced plastics for the auto-mobile and aerospace industries.

Does that mean that linking up to customersystems is an issue?

Thomas Gries: Yes, of course. But this notonly plays a part in tracking and tracing.With a link to the company systems andthe corresponding MES tools, flexible pro-ductions can of course be better exploitedand gain in productivity as a result.

How do you see the support of Siemens forProfinet as a general, standardized fieldbus system in this context?

Thomas Gries: Profinet is becoming in-creasingly important. In that respect it isof course an advantage to the whole textileindustry when such an important automa-tion manufacturer commits itself to fur-ther development of the Profinet standard.Profinet enables not only the integrationin the company system but also telemain-tenance or spare parts deliveries via theInternet are no longer a problem.

Professor Gries, thank you for talking to us.

5TRENDSInnovative automation for the textile industry

Professor Gries, what role does automationplay in the textile industry?

Thomas Gries: The textile industry is oneof the most automated industries of all.That has a tradition because mechaniza-tion began very early in the manufacture oftextiles – just consider the punched cardsin weaving. Of course, the degree of auto-mation today depends on the location andthe textiles to be manufactured. In Asia,for example, the basic clothing textile re-quirements are produced in very wage-in-tensive and therefore hardly automatedproductions. In Europe on the other hand,more and more attention is being paid tohigh-tech textiles but also to mass articleswith the fastest and most reliable marketavailability for the technical field.

Your motto is: Cost-effective productionthrough intelligence. How important isintelligent automation for you?

Thomas Gries: It all depends on what youunderstand by that of course. I find it veryimportant to simplify gears, for example,that is to use direct drives wherever possi-ble. Use of single drives instead of a verti-cal shaft is also very useful and intelligent

The motor modules (power units) ofthe Sinamics S120 Booksize versioncover a power range of 1,6 to 107 kilo-

watts. In this performance range, all mod-ules have the same height and depth. Onlythe width varies between 50 and 300 milli-meters. For driving large extruders, motormodules up to 1200 kilowatts in the chas-sis variant are available. Because of thiswide power range, plants can be suppliedboth in single and group drive configura-tions.

Due to the small size of the SinamicsS120, no space problems are to be expectedin the switch cabinet even in existing plants.Further optimization of the space require-ments is achieved by using double axismodules.

Regulation and data storage

Control and data storage tasks are per-formed in the central control unit CU320 ofSinamics S120. All configuration data arestored on a standard memory card (CFcard). If a motor module has to be changedthis can be done with live wires so that pro-duction can continue immediately afterinstalling the replacement module. Thepreviously required parameterization isno longer necessary because the CU320sends all the data to the motor module.Since the data of all drives are available onthis one module, the configuration of a set-point cascade with the aid of the graphicconfiguring and commissioning tool Starteris very easy.

SYSTEM SOLUTION

The right specific platform for eachdrive-specific control task can be found inthe various control units the Sinamics sys-tem has to offer. The CU320 module con-tains all textile-specific functions as pre-sets. It can control ten motor modules inU/f control aswell as the feeder moduleALM (Active Line Module). Communicationwith master systems takes place via Profi-bus. Sinamics S120 can control both asyn-chronous motors and Siemosyn synchro-nous motors with a frequency accuracy of0.01 percent and therefore surpasses therequirements of most applications.

When using a Simotion D, which is sim-ply plugged in in place of the CU320, theuser can use the programming languageKUP/FUP according to IEC61131 in additionto the control functions. The user can alsoaccess tested functions such as wobbling orchanging fault process. In addition, thismodule allows linking the drives system toEthernet.

Feeding by choice

For feeding tasks, the customer can choosebetween the BLM (Basic Line Module) as adiode bridge with brake chopper/brakeresistance, the SLM (Smart Line Module)as IGBT bridge with feedback facility, andthe ALM (Active Line Module) as an upwardadjuster. The control of the ALM is able tohold the intermediate circuit voltage con-stant when the input voltage drops. Thismeets the requirements from the chemicalfiber industry to control mains voltageinterruptions at 50 percent for 500 milli-seconds. �

Toho Tenax Europe GmbH belongs tothe Japanese Toho Tenax Group andis the largest manufacturer of carbon

fibers in Europe. With 180 employees, thecompany supplies the high-performancecarbon fibers found in aircraft, wind power,automotive, marine, and many other appli-

cations in which high-strength structureswith the lowest possible weight are impor-tant. The new Airbus A380, for instance, con-tains numerous supporting parts made ofthis extremely light and versatile material.

To meet the increasing demand for car-bon fibers worldwide, Toho Tenax has begun

construction of a new production line at theOberbruch site in northern Germany. One ofthe challenges of the large-scale project isthe relatively tight schedule. The plant is togo into operation in the summer of 2006 tosupply the constantly growing market withan extra 1,700 tons of this internationallycoveted high-tech material a year.

From basic to detail engineering

Siemens initially received the order fromTenax for the basic engineering, which wascompleted in August 2004. Because thatphase of the project went smoothly andthose responsible at Tenax were impressedby the competence of the Siemens team,Siemens also secured the contract for partof the customized solution in October 2004.Siemens is handling the detail engineer-ing, including supervision of the installa-tion and safety coordination. In March 2005,Toho Tenax contracted Siemens to providethe rest of the components for the cus-tomized solution, including the process

Projectpartners who are familiar with the peculiarities of the industry in question areindispensable for successful execution. Capitalizing on the process-technicalexpertise and production knowledge of Toho Tenax, Siemens demonstratedthe advantages of having specialists from different disciplines working handin hand with customers to create a consistent solution: fewer interfacessimplify the implementation of the project.

automation based on Simatic PCS 7 (drivetechnology, switching systems for themotors, uninterruptible power supply, andtransformers).

A single-source provider

Siemens is able to equip the entire plant asa single-source supplier and therefore con-siderably reduce the duration of the proj-ect. In addition, Siemens products and sys-tems are backed by a high level of develop-ment competence and broad technical sup-port. Together, these aspects result in highinvestment security – a major considera-tion for a modern, future-oriented com-pany nowadays, and another importantfactor in the decision to place the orderwith Siemens.

Toho Tenax has long years of experiencewith Siemens products and uses the Tele-perm M process control system in its exist-ing plants. Based on this positive experi-ence, Toho Tenax decided to implementSiemens technology in the new production

line as well. Simatic PCS 7 and Profibusoffer integrated intelligence right down tothe field level – a factor that was particu-larly convincing. Thanks to Totally Inte-grated Automation, everything from fielddevices to the process control system isguaranteed to fit together perfectly, andthe entire workflow, from incoming goodsthrough production to delivery, is linked ina single, integrated system.

Experience pays off

With its interdisciplinary competence inboth plant design and automation technol-ogy, Siemens offers bundled expertise that isunique in the industry, and that can reduceproject lead times. Many project steps canrun in parallel because the required expert-ise is in the same hands. For example, thetime required for the mechanical installa-tion took two weeks less than originallyscheduled.

Similar results are expected for the com-missioning phase. Here, those responsible

for the project estimate that it will take fourweeks less, solely due to the fact that theconsistent use of Profibus PA creates con-siderable synergies. Another aspect of theproject is also particularly interesting: TohoTenax will be working on the further opti-mization of its production process duringthe detail engineering and building of theplant. This simultaneous engineering is noproblem for Siemens. The expected modi-fications will be integrated directly into thecurrent project steps.

Conditions are therefore ideal for TohoTenax to provide expanded productioncapacity to a market hungry for the versa-tile carbon fibers – right on schedule in thesummer of 2006. �

CASE STUDY

Manufacturing nonwovens is thefastest growing segment of thetextile industry. Household,

hygiene, medical or technical – the areasof application for nonwovens are almostinfinite. With its present nonwovens port-folio, Neumag, a Business Unit of Saurer,covers the most important key technologiesand processes for nonwovens production.Consequently, they offer their customersnot only extensive solution expertise in dif-ferent manufacturing technologies, but alsothe possibility to take new roads in thedevelopment of innovative nonwoven prod-ucts and processes by combining individ-ual technologies.

Siemens technology in the NeumagTest Center

After acquiring Ason in 2002, the openingof the SSC at the beginning of 2004 was afurther milestone in the development ofnew area of business. A spunbond plant isnow in operation in Neumünster and isdesigned for both customer tests and fur-ther development of the technology. Theplant technology is distinguished by itshigh production performance and spin-

ning speed as well as its great flexibility.This is last but not least due to the fact thatNeumag has relied for decades on theproven drive and automation technologyfrom Siemens. The whole line is controlledby a Simatic S7-400 PLC, the individualplant sections are connected to Simatic S7-300. High plant availability and reliableproduction output are guaranteed by theconnection to the proven Simovert Master-drives drive system. The motors – from thesynchronous servo motors 1FK and asyn-chronous servo motors 1PH to the standardmotors 1LA – also contribute to this. Com-fortable and trouble-free operation andmonitoring is also crucial in the spunbondproduction. Therefore, Neumag has cho-sen the robust Simatic Rack-PC IL40 withWinCC.

New line consistently automated

The consistency of this automation solu-tion, which simplifies the communication,configuration and data storage, is alsoappreciated by the customers. Two neworders won by Neumag have also been fullyautomated with Siemens. The company hasdelivered a line for manufacturing nonwo-

vens from bi-component fibers to the Ital-ian nonwoven producer Albis. The chemi-cal fibers from two bonded polymers areproduced in a width of almost five meters.“The use of the Neumag/Albis spunbondtechnology contributes ideally to the devel-opment and manufacture of new, innova-tive nonwoven products”, Gianni Boscolo,President of the Albis Group states.

The turnkey project with the Iraniancompany Mishabi Baft includes an SMSconfiguration with a product width of 3.40meters. Three spinning beams (spunbond,meltblown, spunbond) are installed insequence. With the SMS method a multi-level nonwoven fabric is produced com-bining different fabrics with different prop-erties. Meltblown fibers, for example arevery resistant to liquids due to their highbarrier effect. These “sandwich” nonwovensare used, for example, in baby diapers. �

In the textile industry high ambient tem-peratures, vibrations and restricted instal-lation space often create conditions which

are too much even for industrial PCs. In theindividual applications or small series typ-ical for textile refining, the time, work andcosts necessary for adapting the system donot pay in many cases. Under these consid-erations a system solution evolved with theSimatic Microbox PC 420, the (resource-optimized) operating system Windows XPembedded (XPe), the PC-based controlSimatic WinAC and Simatic HMI.

The Simatic Microbox PC 420 is charac-terized by great robustness, reliability, lowspace requirements and low engineeringcosts. The integration of drives so impor-tant to the textile industry is implementedfuture-safe by Profibus and Industrial Eth-ernet. The Sinamics drive system especiallyis an integral part of an automation solu-

tion with Microbox PC 420. One applicationemphasis in the textile machine industry isfor the segments textile refining, area man-ufacture and nonwoven.

Familiar programming environment

The Soft-PLC WinAC is programmed withthe tools of the Simatic world under theproven Simatic Manager. Central engineer-ing via Industrial Ethernet or Profibus is alsopossible. Programs or program parts forSimatic Controller can easily be ported toWinAC. Technological applications suchas measured value acquisition systems orimage data processing can be integrated inthe control network with the Open Devel-opment Kit (ODK) of WinAC. An open datainterface based on OPC (OLE for ProcessControl) enables the vertical integration ofstandardized office software for access toprocess data. The integrated OPC server

also supports communication with non-Simatic OPC clients so that customer ownHMI software under Java can be easily inte-grated in the current Microbox PC 420.

No rotating parts

With a size of just 262 x 132 x 47 (in millime-ters) and the robust full metal housing, theMicrobox PC 420 is suitable both for assem-bly on a standard DIN rail in the switch cab-inet and for external wall mounting or instal-lation in the machine. The standard versionhas no rotating components such as a harddisk and fan which are probe to shock anddust. Compact Flash Cards (CF) are usedpreferably as memories. All components aredesigned for fan-less operation round theclock at 50 degrees Celsius. The high vibra-tion and shock-resistance of the MicroboxPC enables it to be used in areas previouslyreserved for a dedicated PLC.

Robust PC technology

PC-technical basis are Intel processors withmain memories up to 512 MB and a Siemensmotherboard. All normal PC interfaces,an optional Profibus DP interface, a DVI-Igraphic connection and three free slots forPCI cards in PC/104-Plus format are avail-able for the peripheral link. The 128 kBSRAM (Static RAM) is (battery) buffered andthe integrated 24V power supply with poten-tial isolation bridges power failures up to 15milliseconds. Additional data security isoffered by the integrated monitor functionsfor voltage, temperature and program run(watchdog). �

CASE STUDY

The Marzoli Spa in Brescia Italy, a sub-sidiary of the Camozzi company isone of the few companies which has

specialized in the production and deliveryof all kinds of spinning machines and pos-sesses an equally high technical know-howin the field of processing of cotton, syn-thetic fibers and their mixtures – from thebale to yarn production by the ring spin-ning method. The conclusion of a Joint Ven-ture with Dongtai in China opens up newperspectives and expansion possibilities forthe Italians in a fast growing market.

The right solution for every machine

As an internationally operative companyMarzoli was looking for a new partner sup-plier of international reputation who metthe requirements for quality, market pres-ence, development of suitable solutionsand technical competence and found themin Siemens. The relations between the twocompanies are based apart from good coop-eration on the search for the best solutions.

The optimum integration of the systemsduring the planning phase of the machinesensures reliability and cost optimization.This continues through to the technical sup-port during prototype development and thetest phase. Each party can contribute theirown experiences in a constant exchange ofinformation.

Thanks to the wide variety of the Siemensautomation portfolio the best solution fora certain machine was always found. A highlevel of standardization and uniformity ofthe system simplifies the end customer’suse of the machine. The carder C601N,the roving frame FT-2N and the combingmachine CM500N were therefore devel-oped on the Simatic S7-300 platform withdrives from the Simodrive 611U series,Micromaster 420 and 440 converters, asyn-chronous motors 1LA7 and brushless servomotors of the 1FK7 series. The machinesare operated by the new Simatic TP 270Touch Panels. The visualization was devel-oped with the standard system Protool/Pro.

This guarantees maximum efficiency andsimple handling.

Distributed control solution for many axes

Marzoli has developed a series of ring spin-ning machines with the new Motion Con-trol solution Simotion and the SinamicsS120 drive family which are ideal for thismachine type: the ring spinning machinesMP-1 with tangential belt and “band” and thenew, double-headed draw frames DMT-R.

The ring spinning machine MP-1N con-sists of six axes (asynchronous motors withencoders) which are linked by DC-Link andsupplied by a I/O module. This enables anyvoltage interruptions to be compensatedand controlled switch-off of the machine isguaranteed in the event of a power failure.

The machine is controlled by the newmotion control system Simotion D 425. Thisis positioned next to the drives and com-bines motion control, logic and technologyfunctions. It also manages the control of the

Partnership between Marzoli and Siemens is bearing fruits

Quality ring spinningThe textile machine company Marzoli-Vouk has maintained a synergetic partnership withSiemens for years. This has enabled them to implement solutions tailor-made to exactlysuit the respective machine. The automation of the new series of ring spinning machineswith Simotion and Sinamics optimally supports the machine functions.

setting rings for speed and axis current. Byusing Simotion, the logic, motion controland monitoring of the machine can be com-bined in a single system with a single de-velopment platform. Thanks to the drive-based property of Simotion D it was alsopossible to accommodate the control to-gether with the drives and the converter forthe current consumer control in a singleswitch cabinet in the rear section of the ma-chine. The wiring of the field sensors of therelevant machine part could also be reducedby installing a distributed periphery. TheSimotion-Sinamics system also favors themodular setup and therefore allows a veryflexible adaptation of the ring spinning ma-chine to customer requirements. MP-1N ismanufactured in sizes from 600 to 1296spindles for instance. The power of the mainmotor is load-dependently variable from 45to 75 kilowatt, a low consumption is guar-anteed by high-powered motors.

The Ethernet interface of the Simotion D425 enables the connection of the machines

to the monitoring system of Marzoli, toacquire production and performance dataand transfer parameter recipes to the field.A constant remote monitoring and main-tenance of all systems is also possible viathe Ethernet interface which reduces thetime and costs of any modifications con-siderably.

A single engineering system optimizes the work

The Simotion Scout engineering softwarewhich contains all the necessary instru-ments for the various phases of the machineautomation not only makes the develop-ment easier but also simplifies the work ofthe service technicians. Only one device isnow necessary for the software update ofthe machine, parameterization of the drives,control of the distributed I/O cards and theonline diagnostics in the whole system.

CASE STUDY

The Freudenberg company used toproduce its machines for nonwovenson its own. Today, individual machine

modules such as fiber preparation, carder,calander or winder are purchased from spe-cialized vendors and combined in efficientlines. A uniform automation technologywith consistent communication is requiredfor this. “We still automate key modules

ourselves, especially such as the carder –if only to better protect our special know-how”, Dipl.-Ing. Wolfgang H. Kissel, Head ofProcess Technology and Automation atFreudenberg, stresses.

Tailor-made automation concept

As a worldwide producing company, Freu-denberg has chosen Siemens as a supplier

because the automation provider offers ascalable and integrated product range inaddition to worldwide presence, availabil-ity and support. Siemens automation tech-nology is the preferred solution especiallysince the introduction of the new S7 gen-eration, which was also well received onthe US market. “We try to standardize wher-ever possible. That streamlines the spareparts stocks and also simplifies operatortraining as well as maintenance in the fac-tories. Many of our suppliers also rely – forgood reason – on Siemens’ products so thatwe had little trouble convincing them. Onlyrecently, another supplier also made theMP370 operator panels with touch screen,which we prefer, their new standard”, Kisselrelates.

Each of the larger machine modules hasits own programmable logic controllerSimatic S7-300. The PLCs are connectedboth to each other and to two Simatic S7-400 master controllers via Ethernet. Oneof the master controllers coordinates theline, the other controls the fiber propor-tioning exclusively at the inlet. There is aMulti Panel Simatic MP370 Touch on everymodule for local HMI, with two panels on

High standard fornonwovensWith one-stop automation technology, the leader manufacturer ofnonwovens, Freudenberg, produces integrated, high-efficiencyproduction lines from individual machine modules. A uniformoperating concept for all modules is essentially responsible forreduced spare parts stocking, more efficient configuration andcommissioning, as well as simplified training, process control andmaintenance.

the card. Using the efficient Scada systemWinCC, the whole line can also be con-figured with drive programs as well asmonitored from a central position. Approx-imately 70 single Simovert Masterdrives are electronically coupled and linked totheir controllers, like the distributedSimatic ET 200M and ET 200S devices, viaProfibus DP.

Distributed operation and monitoring

Another decisive aspect for Freudenbergfrom an automation technology point ofview was that the Simatic Multi Panels canbe integrated smoothly in “Totally Inte-grated Automation” (TIA), the integrated,comprehensive concept from Siemens.That means: configuration and program-ming on the same platform as drives andPLC, simple communication and uniformdata storage. This concept considerablyreduces expenses because the SimaticMP370 Touch has all the common inter-faces such as Ethernet, Multi Point Interface(MPI) and Profibus on board and can there-

fore be integrated quickly and withoutadditional hardware in networks. Sincethere is a panel on every technology unitin the line, the different suppliers canoptimize their units independently of oth-ers and commission them faster on site.The decentralized operation also simpli-fies maintenance and diagnostics of run-ning machines from controller to the indi-vidual drive. The Freudenberg technicianshave implemented special service func-tions for Profibus and drive diagnostics.Remote access is possible through theIntranet to support the operator locallywith the identification of failures.

Simple operation, fast engineering

The touch control is very well received atFreudenberg’s factories abroad. It con-vinces the users with simple, intuitive andoperating structures with a low suscepti-bility to errors. On the graphic-capableMulti-Panels MP370, much more infor-mation can be clearly visualized than ona text display. The large screen has deci-sive advantages, especially on the tech-nologically sophisticated card with itsapproximately 25 individual drives. Addi-tionally, it is easier to select a drive tap-ping your finger on the touch screen thanby mouse or keys from a long scroll list.Last but not least, the multilingual userinterface simplifies working together inter-nationally.

“In the implementation of the HMI con-cept, the ProTool/Pro configuration toolsused for all Simatic Panels and the experi-ence from earlier projects always savemore and more time. That allows us toshorten engineering time by about onethird”, Wolfgang Kissel is convinced. Infuture, Freudenberg is planning to reducethe variety of the bus systems and have theentire machine communication run uni-formly on Ethernet. The new configura-tion and visualization tool WinCC flexible,which is fully compatible with the last ver-sion, will offer even more possibilities inthis respect. �

InternationallysuccessfulFreudenberg is a globally activecompany with 28 production sites inEurope, North and South America,South Africa, and East Asia. Thecompany is a technology leader andthe largest as well as most versatilenonwoven producer worldwide. Itdevelops and produces nonwovens for a wide variety of different tasksand requirements in the divisionsInlay Materials, Filters, TechnicalNonwovens, Hygiene/ Medical andTuft fleeces.

The lead in technology today is not as big as it once was, so to keepits competitive edge, the company isfocusing its competencies.

This includes increasing productionabroad as well as concentration atsites. An important prerequisite forthe worldwide competitiveness is ahigh degree of automation in theproduction plants.

R aschel machines for manufacturingcurtains are among the most sophis-ticated representatives in the warp

knitting machine family. They require avery complex technology because mechan-ical and electronic components have to beadapted to each other with maximum pre-

cision. Liba therefore decided to thoroughlyrevise the existing machine series in termsof mechanics and electronic pattern selec-tion. The result is a machine which sur-passes the predecessor series in all impor-tant aspects. Constructional measures havesuccessfully led to a considerable reduction

in noise and vibration levels as well as energyconsumption. The productivity could alsobe increased considerably with a main shaftspeed increased to 750 rpm.

Perfect pattern selection

For the electronics of the Jacquard patternselection system, they chosetechnology and equipment fromSiemens Automation & Drives(A&D) because A&D already hada considerable know-how fromthe technically related field ofJacquard knitting and was ableto offer a complete one-stopsolution.

The Jacquard pattern selec-tion system Sitex consists of theJacquard controller which isoperated by the corresponding15-inch touch display and theJacquard selection cards basedon modern piezo-technology.These key components are sup-plemented by power supply tai-lor-made for the application, ahigh-precision unit for positiondetection of the main shaft anda temperature/humidity sen-sor.

CASE STUDY

Modern piezo-electronics in curtain manufacture

A pattern for all tastesAt the ITMA 1991 in Hanover, the Upper Franconian mechanical engineeringcompany Liba demonstrated its first Jacquard device for raschel machines. Sincethen, a number of further developments and improvements have been noticeablein this field. Especially the innovation of the machines with the Siemens patternselection system Sitex led to a considerable growth in productivity.

speed as well as pattern change withoutannoying waits are guaranteed by thereal-time operating system. The piezoselection cards implement the patternspecified by the control absolutely syn-chronous to the machine clock to theexact pixel. Another advantage of thecards: They are maintenance-free andextremely long lasting, need little energyand only emit little heat to the environ-ment in comparison with magnet actu-ators – properties which are much appre-ciated in the textile industry.

In the harsh environment of textileproduction, even an extremely robustsystem is not totally immune to faults inthe long term. A number of monitorssuch as the parity check of the data trans-mitted to the Jacquard actuators, is there-fore integrated in the system. It simpli-fies necessary troubleshooting enor-mously. The technical specialists at Libacan access all the relevant operatingdata by a telediagnosis system and inmost cases avoid time-consuming andcostly machine downtimes and serviceassignments in typical end user coun-tries such as Egypt, Turkey or China.

A success story “made in Germany”

The machine was producing perfectgoods just six months after beginningthe project. Wolfgang Jahn, Project Man-ager for the RACOP JF P 3/1 at Liba, is stillimpressed by the fact that the machineworked perfectly the first time the soft-ware was installed. The speed at whichSiemens successfully completed theircontribution to the total project alsototally met the expectations. The com-pany also found it positive that Siemens

acted like a medium-sized company as faras flexibility, speed and consideration oftheir partners requirements in this projectwere concerned. Head of Development,Peter Mayer, speaks with satisfaction of oneof the best projects in recent years.

The machine has since fulfilled thestrict release criteria prescribed by Libaand has reached series maturity. The com-

bination of mechanical engineering andknitting-technical competence on the onehand and automation experience on theother hand has led to a result that hardlyleaves any wishes unsatisfied in curtainproduction. �

Innovative medium-sized company and “global player”The Liba Maschinenfabrik GmbH in Naila is one of the world’s most renowned manu-facturers of knitting and warping machines. The company can look back over a 60 year company history and includes a wide range of warp knitting machines, weftingmachines, raschel machines and warping machines in its portfolio. Although Liba is amedium-sized company that can respond quickly and flexibly to its customers require-ments it is still a real “global player” which is active worldwide – with branches inFrance, the UK, the USA and Hong Kong. The company focuses not on the massproduction of as many simple machines as possible but is particularly proud of being an innovation leader. The result are technically sophisticated machines of the highestquality and maximum life endurance. �

Modern textiles need to meetincreasingly higher demands.Properties such as wind and water

proof, actively breathing, crease-proof,anti-bacterial, flame-retardant and fire-safeand highly elastic are the market require-ments. The thread lengthening principle isapplied for stretchable textiles regardless ofwhether knit or woven. Due to the differ-ences in the speed of the drives betweenbobbin creel and warping machine there isa difference in length of the elastic threadwhich is first stretched and then relaxed.This avoids later changes in the thread ten-sion due to aging or climatic factors.

A further developed product of the Libacompany is an elastic warping machine inseveral versions for warping of elasticthread on loom beams of different widths.The automation has to take into accountthat it had to be possible to warp all beamsidentically starting with one warped masterbeam. This is the basic prerequisite for alater uniform thread processing in weavingor knitting where exact laying of the threadand exact thread tensions on the loombeams are crucial.

All the data at a glance

By displaying all the latest warp beam datasuch as number of windings, diameter,

stretching and relaxation factors exact evi-dence of the quality tracking can be pro-duced. In a visualization mask created bythe ProTool configuration software for aSimatic Multipanel MP 370, it is possible togenerate and document warp-specific inputmasks, curves (support value tables), relax-ation curve graphics and regenerations aswell as new generations for speed ratio set-ting and thread position orientation to suitthe user. With the Simatic Multipanel MP370, which has no hard disk, in conjunctionwith a Simatic S7-314-2 DP PLC includingonboard counters and fast I/Os, a branch-specific automation solution has been cre-ated. Helmuth Wirth, Group Leader forWarping Machine Control at Liba reports:“With the free convertibility of the existingSimatic S5 function components to the S7profile and the changeover of the PC visu-alization interface to the HMI configurationtool ProTool integrated in Simatic S7, theuse of standard components in the machinecontrol was successfully implemented. Atthe same time we achieved a quality leap inthe machining process.” The automationsolution with standard components andengineering tools made it possible to imple-ment all functions largely by configurationinstead of by effortful programming as pre-viously.

cycles. In addition, the automatic detectionof the up and down movements are dis-played relative to the sewing head position.In conjunction with a high-performancePLC and the proven dynamic componentsof the Simodrive 611U drive system, thecontrol cycles created on the CAD/CAM sim-ulation system can be converted quicklyand machine-compatibly into sewing cyclemovements and transferred via Profibus.This efficient and easy solution has provenits values as Jörg Rippert, head of develop-ment and design at KSL confirms: “Withthe Sinumerik control, we can transfer com-plicated sewing cycles from a CAD/CAM sys-tem to the sewing robot and project anycontours two-dimensionally. In addition,our customers can create sewing structureslocally themselves, develop customizedsewing patterns, and implement themautomation-technically without softwareknowledge.” �

The Keilmann SondermaschinenbauGmbH (KSL) in Lorsch/Hessen, in co-operation with Siemens, has devel-

oped a fully automatic CAD/CAM couplingfor controlling a sewing portal, which workstogether with a Kuka sewing robot head.The result is a freely programmable CNCsewing machine that enables modular ma-chine structures that have an extremelylarge sewing field diameter. A sewing headthat can be fully rotated, moved and de-tached, and offers needle transport and dif-ferent stitch types enables two-dimension-al execution of exact sewing patterns withthread pulling in all sewing directions. Thesewing portal drive is similar to the feederdrive of a machine tool. It is the lower-levelmotion control to control sewing of partsthe size of aircraft wings. The heart of the3D sewing system is an industrial sewingrobot with joint kinematics for all point-lane control tasks. It allows 3-dimensioningsewing of technical textiles and operatesalternately with 2D sewing machines. Sincethe textile material now no longer needsto be moved, the sewing field size corre-sponds to the range of the portal.

Simple sewing of complicated parts

Using the Sinumerik 840Di machine toolcontrol, it has been possible to save specialsewing cycles as a DIN code in process cy-cles. Parameters such as setting X and Ysewing axis positions, stitch length, sewingspeed etc. are converted from the external-ly generated program code into the G-codeof the controller by the CAD/CAM systemand loaded in the numerical control (NCU).Without any knowledge of G-code pro-gramming, the user can also make graphi-cal program changes locally. For example,work step programs in the sense of a mod-ular machine can be integrated locally us-ing a specific software. The use of the PCU50 also allows direct use of HMI-advancedservices, parameters, diagnostics, and com-missioning.

Altogether, the Sinumerik 840Di con-trols two swivel axes, two needle coils, twogantry portal axes and one axis for the trans-verse motion. From this automation solu-tion, the end customer gets a clear programrepresentation as a work step program aswell as the input graphic for contours and

In addition to the sale of large circularknitting machines, the Beck Textilmaschi-nenhandel GmbH performs extensive

and technically sophisticated retrofit workas well as the conversion of mechanical toelectronic machines. This flexibility enablesthe company from southern Germany toassert itself next to the big names in theindustry despite the hard pressure of com-petition. This is confirmed by the activitiesin the Czech Republic, China and the East-ern European countries Poland and theUkraine.

Single needle selection with manypattern possibilities

Beck has been equipping its Jacquardmachines with Sitex for many years. Underthe brand name of Sitex, Siemens sells acomplete system for the electronic singleneedle selection on Jacquard circular knit-ting machines which includes the controlSitex CK, the uninterruptible power supplyunit Sitex S and the piezo-actuators Sitex M.The controller accepts pattern files in a large

number of different formats which it inter-prets and processes for the knitting process.By appropriate control of the piezo-actua-tors, the movement of every single needle iscontrolled absolutely in sync with the move-ment of the needle cylinder for every singlestitch. The uninterruptible power supplynot only powers all the system componentsbut also ensures that operation can con-tinue without misselections even after apower failure. The machine operator has acomfortable user interface at his disposalwhich is made easier by a pattern preview.The long-lasting and quiet piezo-actuatorswhich operate with a minimum of energyhelp to minimize the heat developmentduring operation. In addition, it is easy toreplace individual actuators because no set-ting processes are required.

Trend towards ultrafine stitches

Just a few years ago, E28, that is 28 needlesper inch, was the maximum fineness thatcould be achieved on electronic Jacquardlarge circular knitting machines.

But the trend towards even greater fine-ness is unstoppable: Beck now has severalE32 machines and since a few months agoeven an E36 machine in successful opera-tion. It manages an impressive 18 revolu-tions per minute with 72 feeders at a cylin-der diameter of 30 inches.

At the moment, the machine manufac-turer is even giving intensive considerationto an electronic E40 machine which will beused above all for ultra-fine, elastic materi-als in bodywear. With this sophisticatedJacquard knitwear, in which it is hard todetect by what techniques they are made,a small premium segment of the marketcan be covered.

To ensure that machines with such afineness work without any trouble, Beckhad to master numerous technical chal-lenges: on the one hand concerning thestitch-forming elements of the machine, onthe other hand concerning the design of thepiezo-actuators and their control. Siemensproved a competent and flexible partner tohelp putting these innovative ideas intopractice quickly and successfully.

For E32, the power reserves of the Sitex,actuators were sufficient so that the Sitexstandard modules could be used withoutmodifications. In the E36, customized piezo-actuators were made to the specifications ofthe Beck technicians that immediately ful-filled the tasks demanded of them. And asfor the E40, there are already draft conceptsfor solutions so that both parties are sure ofbeing able to take this hurdle together. �

Beck relies on Sitex in circular knitting machines

Ultrafine JacquardknitwearThe textile machine company Beck sells the machines of the renownedItalian company Orizio as a general representative for Germany and 26 othercountries. At the same time, the company does a busy trade with second-hand machines of various manufacturers.

By tradition, many weaving machinemanufacturers build their owncontrols. Shorter and shorterinnovation cycles in automationtechnology, however, are triggeringnew requirements from end users –they want more functionality for thesame price. The “do-it-yourselfbuilders” among the weavingmachine manufacturers therefore seethemselves confronted by a highpressure of innovation whichcontinues to increase.

This situation also intensifies the prob-lems of version monitoring and main-tenance and spare parts stocking for

modules and components for the in-housedevelopment of hardware and software.The aforementioned dynamic leads to pro-gressively increasing costs for automationcomponents provided in-house and thusto a growing challenge to the company –although the wishes of the end customersare becoming increasingly difficult tosatisfy.

Strategic alternative

Standardized automation solutions, whichhave long been the norm in other indus-tries and industry segments, provide a wayout of this situation. They serve as a hard-ware and software system platform for thefunctionality required by the machine man-ufacturer. The Siemens solution for weav-ing machine automation is based on provenmotion control technology, and for the firsttimes combines the concept of a platformsolution for the weaving machine automa-tion with mechatronic principles and spe-

cific technology components. Hardware andsoftware are very easily scalable to meet therequirements of the individual machine orthe end customer. The solution includes allthe basic functions of a weaving machine asstandard, including easy-to-use, guidedcommissioning, service and telemainte-nance functions. The system concept basedon the product series Simotion and Sina-mics provides both the necessary opennessand the necessary power reserves for addingindividual, manufacturer or customer-spe-cific functions.

Standard plus x – “out of the box”!

The basic solution supports projectile, rap-pier and air jet weaving machines. All thebasic production data are recorded differ-entiated and in detail as standard. Thedowntimes are coded precisely according tothe cause of the fault for downtime analy-sis and preventive maintenance. A net-work connection also serves for linking theweaving machine to production planningand Manufacturing Execution Systems ifrequired.

Good. But discretely, please!

As a standard, the Simotion C, Simotion Por Simotion D (controller, PC or drive based)platforms are available for the scope offunctions described roughly below:• constant speed ratio of warp let-off and

take-off depending on the main drive• accurately clocked weft insert• fast, true positioned provision of weft

according to color selection• increase in machine cycle number

• different weft insert techniques byprojectile, air jet or rappier

• reproducibility of the process data• pattern management and processingOn request, the solution can also be adaptedat low cost and without major adaptationsto a customized platform with operatorpanel. All HMI functions are prepared tothe extent that they can either be useddirectly or can be integrated smoothly anddiscretely in the normal optics of the weav-ing machine manufacturer’s user interface.In addition to support for the introductionand individual adaptation of the industrysolution to the respective company, Siemensalso offers mechatronic services. A morequiet machine operation, higher weavingperformance and less maintenance are theimmediate benefits from this mechatronicoptimization. In addition, valuable infor-mation for the constructive further devel-opment of the machine can be gained fromthe results.

Focusing on key competence

The platform solution from Siemens givesthe user complete freedom for applicationspecific engineering of his weaving ma-chines. The tasks of the development depart-ment change, the development times (time-to-market) are optimized and the costs fordevelopment, version maintenance, spareparts stocking and services become man-ageable and controllable again. �

TRENDS

In the last five years, Siemens Automa-tion and Drives has achieved two-figuregrowth rates in China and has gained

the market leadership in the field of automa-tion and drive technology. More than 2,600employees, seven companies and 44 localoffices are present in China, and for 2005,it is planned to expand the sales and serv-ice network to 60 offices. These activitiesare complemented by a strong local pres-ence and local expertise that allow Siemensto grow with the market and adapt to newrequirements.

Different strategies for conquering the market

The Chinese market for automation tech-nology continues to grow. Siemens benefitsfrom this by entering strategic partner-

ships with local system integrators sincethese companies are always on the lookoutfor the latest technologies. With TotallyIntegrated Automation, Siemens providesan excellent automation platform for betterproduction visibility, a crucial factor forinternational competitiveness. After all,many of the plants in China are producingnot only for domestic but also for globalmarkets.

To improve access to the Chinese mar-ket, local partners are just as importantas global strategic partnerships and thedevelopment of in-house know-how. Thisincludes an extensive offer of services forcustomers. On a nationwide hotline net-work, service staff provide solutions toproblems within 2 hours. Training Centersin various cities pass on knowledge of new

Constant yarn quality – compact spinning with S7-300

A pilot solution for a compact spinningmachine, implemented by the Zhejiang RifaTextile Machinery Co. Ltd., has been in oper-ation at an end customer facility since June2004. With the compact spinning machineRFCS510 , very high quality threads of cot-ton, chemical fibers or mixtures can bemade which can then be woven or knitted.The demands on the automation system forspinning are high: For optimum quality, thesystem must perform compli-cated process calculations andprovide reliable synchronizedcontrol of position and torque.To achieve a perfect qualitythread, exactly maintaining therotation speed setpoint is nec-essary. The position controlledring rail ensures an even wind-ing tension and good coil for-mation.

The PLC Simatic S7-300 headcontroller constantly monitores

Since 2001, Siemens has equipped 40 sizing machines in China forweaving preparation. The sizing of the thread before weavingsmoothes and strengthens the warp threads to make them betterable to withstand the stress of weaving. A good sizing quality – thatmeans, an even size application, perfect thread tension, and cor-rect degree of drying of the warp – has a direct effect on the effi-ciency of the weaving process.

To meet the high sizing requirements, many machine manu-facturers develop 7-axis machines which need a powerful drive sys-tem. Simovert Masterdrives MC Compact Plus converters in con-junction with a DC busbar and seven inverters, Active Front End(AFE) and synchronous servo motors form the nucleus of theautomation on the basis of Totally Integrated Automation. The syn-chronous servo motors have a very low power consumption dueto their high torque – the total power consumption is less than 40kilowatts. In addition, another 50 percent of the energy consumedcan be saved by using the DC busbar and AFE because the recov-ered energy can be fed back into the DC busbar.

A very fast data transfer of twelve megabits per second betweenthe Masterdrives MC drives, as well as the integrated control pos-sibilities for position, speed and torque keep the yarn tension atexactly 0.01 percent. It also remains constant when the machinestarts up and stops and thus guarantees an even thread expansionand size application as well as little thread breakage.

A sensor for the thread tension when winding is not necessaryin this automation solution because it is controlled by a specialwinding software. Warp beam diameters of 110 to 1,000 milli-meters are possible, and the winding tension can be set from 80to 600 kilogram due to the asynchronous servo motor 1PH7 on themain axle.

The machines with Siemens automation are receiving a positiveresponse from end customers in China above all due to their highavailability and low energy consumption. �

Benninger Zell, a member of the Swiss Ben-ninger AG, develops and produces highquality and efficient machines and plantsfor the textile and rubber processing indus-try that are delivered to well-known tirecord manufacturers all over the world.Today, tires of all kinds are manufacturedsubject to strict quality standards (DINISO 9000). The high quality requirementsrequire continuous monitoring of the pro-

Costs for producing high quality tirecord are enormous. After spinning,twisting and weaving the polyester,

nylon or rayon threads, the raw fabric issaturated in latex solution, and then dried,heat treated and fixed. This increases the adhesion to the rubber and improvesimportant physical properties such asexpansion, breaking strain. From the tirecord impregnation plant, the fabric passeson to the tire factories where it is coatedwith rubber on both sides and cut intostrips for use for manufacturing tires.

All process parameters of theplant are therefore set, monitored andrecorded on two redundant PCs. That com-municate via Profibus DP with the plantcontroller Simatic S7-400-2DP.

TIA in impregnation plants for tire cord

It keeps on rollingAs a world market leader, Benninger Zell supplies its plants to all well-known tire cord fabricmanufacturers in the world. Since increasingly high demands are being made on thedurability of automotive tires, the carrier material also needs to satisfy these conditions. With Totally Integrated Automation, the Benninger plants are ideally equipped tomanufacture high quality tire cord.

DC feed, distribution and frequencyconverters of the drives

the plant by pulling mechanisms anddriven roller pairs. Tensions of 1000 to90,000 Newtons are produced between thepulling mechanisms. These tensions aremeasured by tension measuring bars anddigital measuring amplifiers. The measur-ing amplifiers are linked to the PLC viaProfibus – this guarantees a very accurate,trouble-free and high resolution signal aswell as a detailed error diagnosis.

Precision drives guarantee quality

Since continuous operation takes place inthe central part of the tire cord plant, reli-able drive systems are very important. Afterall, the plant runs for days on end withouta stop. Off and on-winders are decoupledby product stores and can be stopped tochange the raw fabric and finished fabricbales. Waste fabric is produced when theplant is stopped, and this is a great loss tothe company. A plant is therefore equippedwith up to twelve drives with a total powerof up to 800 kilowatts. Frequency convert-ers of the Masterdrives type with powerranges from 9 to 220 kilowatts are used,which are coupled and supplied via a com-mon DC intermediate circuit. Dependingon the setting and the operating state of theplant, the drives can be operated either bymotor or generator. The DC intermediatecircuit is powered centrally by a rectifierunit. In addition to standard devices notcapable of feedback, Active Front End (AFE)devices are also used. By using an AFE rec-tifier unit, the duration of the permissiblevoltage drop could be increased consider-ably and the customer's request for highertolerances with regard to the stability ofthe power supply could be satisfied.

The heat treatment of the fabric takesplace in up to ten hot-air ovens. There, fansblow the air heated up to 245 degrees Cel-sius directly onto the fabric webs. To beable to guarantee and document the evendistribution of the temperature, the airtemperature inside the oven is measured inseveral places. For this task, every oven isequipped with up to 20 temperature sen-sors (PT100). A total of up to 250 tempera-ture sensors are installed in one plant. Thedistributed installation of the PT100 mod-ules has considerably simplified the instal-lation and drastically reduced the cablelengths. Every oven is equipped with atleast three fans. All the fans are operated byMasterdrives frequency converters in therange of 50 to 90 kilowatts. The total power

of the fans is up to 2500 kilowatts. Using thefrequency converters allows the air volumein the ovens to be set very precisely: theysave energy and prevent an additional loadon the mains by reactive power in compar-ison with shutter systems.

28Finishing

CASE STUDY

Today, all textiles are subjected to acomplex finishing process beforeconfectioning. Here, washing has a

decisive influence on the quality of the fin-ishing step. Whether for desizing (removalof starch from the weaving process) or afterdyeing, bleaching and mercerizing to finishthe cotton fibers – residue chemicals or con-taminants always have to be washed out.

The Eduard Küsters MaschinenfabrikGmbH & Co. KG in Krefeld, Germany, is aspecialist for textile wet finishing of wovenand knitted goods using floating rollers. Inthe development of its washing machines,the company takes into account both thedifferent finishing processes and the dif-ferent textile constructions. To ensure thatthe right washing technique is used for thespecific task, the company offers made-to-measure solutions – from the classic andversatile “Compacta”, the high-performancewashing machine “TurboFlush” with opti-mized water consumption, to the “Elanit”series, which operates at extremely low-tensions, for highly-elastic knitwear. Everywet finishing machine from Küsters con-sists of individual machine modules thatthe customer can put together individuallyaccording to the requirements of the pro-cess and the goods.

Flexible thanks to distribution

In order to optimally implement this cus-tomized approach also in the automationtechnology, Küsters has chosen a distrib-uted control concept in its textile finishingplants. That means, several independentmachines or modules with their own dis-tributed controls are connected to a centralcontroller and visualization. The standard-ization of the individual washing modules

Modularization in wet finishing

Made-to-measurewashing conceptsThe Küsters machine factory stands for individual finishing plants forall finishing steps and textiles. In order to be able to cope with thenecessary variety, the company relies on a distribution of the controltechnology with Simatic. The seperate mechatronic modules can be configured, tested and commissioned independently of each other.

The distributed controls are imple-mented with Simatic ET 200S with failsafeCPU S7-IM151-7F and the Panel Simatic OP77A. For the first time, Küsters uses the eas-ily and intuitively operable Simatic WinCC-flexible programming tool, which guaran-tees high configuration efficiency due tointelligent wizards and full integration inTotally Integrated Automation (TIA). All dis-tributed controls are connected to the cen-tral Simatic S7-315 DP controller via Profi-bus DP. A Simatic Panel PC 677 with TouchScreen and the proven Conticon softwarefrom Küsters are available for operationand monitoring.

With the introduction of this concept,the internationally active company expectsmuch shorter commissioning times and anoptimized telediagnosis down to the lowestlevel of control. �

CASE STUDY

The CIMI company, located at the heartof the Italian textile industry, buildsmachines for finishing textiles and is

a world leader in wool and mixed fabrics.CIMI is also seeking to improve its positionin the cotton branch. CIMI’s most importantcustomers include such well-known com-panies as Loro Piana, Zegna, Cerruti, Pia-cenza and Marzotto.

The Italian machine manufacturer’s pas-sion for innovation and the availability ofnew technologies from Siemens resulted ina cooperation for examining and evaluatingnew solutions for the operation and moni-toring (HMI) of machines. Simatic WinCCflexible was used for configuring a MultiPanel Simatic MP370 on a machine (Multi-fix) for fixing continuous fibers.

In this process, technically known as“crabbing”, the fabric first runs through oneor more troughs where it is saturated withwater by pressurized nozzles. In the sub-sequent water sack pipe, the fabric is satu-rated with a special chemical and finallyundergoes chemical treatment in a troughwith saturated steam. The nucleus of thisunit is the evaporator. The saturated steamenvironment inside the evaporator is alwayskept at constant conditions due to the steamdistribution system so that the textiles arebeing treated the same conditions through-out. At the end of the process, the fabric iswashed in a rinse tub.

The temperature of the trough with sat-urated steam is PID-controlled using analgorithm running in a Simatic S7 con-troller. This control circuit actuates the con-troller diaphragm valves, which control thesteam inlet into the trough. The tempera-ture must always remain constant because

just a few degrees difference change thecharacteristics of the fabric. The Multi PanelMP 370, flexibly configured with WinCC,monitors the temperature of the steam andthe different tubs as well as the liquid levelin the tubs, and offers the operator the pos-sibility of changing and controlling allprocess phases.

Quickly adaptable and multilingual

Due to different working lengths of the fab-ric, different performance stages can beimplemented in the Multifix, or the qualityof the end product can be influenced bydifferent saturated steam temperatures.WinCC flexible offers optimum support forthis flexibility, especially when the machinehas to be reconfigured frequently. Massi-miliano Morscher, Head of Automation

Technology at CIMI, confirms that changescan be made in a much shorter time withWinCC flexible. With the aid of imageblocks, parameterizable project sets canbe created, which can be used in severalapplications.

Another advantage for Morscher is thepossibility of the multilingual configura-tion for export-oriented companies such asCIMI. With WinCC flexible, it is possible toswitch online between 16 languages. And,thanks to the integrated dictionary, the con-figured texts can be translated automati-cally, which saves a considerable amount oftime and costs. �

A striking success: Simatic WinCC flexible in the textile industry

Flexibility as a program

The Italian textile machine manufacturer CIMI is using Simatic WinCCflexible in one of its machines. The extremely high demands on flexibility,short tooling times, and simple operation are ideally met with theinnovative HMI solution for panel and PC-based, close to the machineoperation and monitoring under Windows 2000 or XP.

The term “Converting” has establisheditself internationally for handlingand processing windable materials.

In general, what all converting processeshave in common is, that the material isavailable in rolled form at the beginning of the process and must be rolled up againor cut at the end. The different materialsand technologies demand individual weband rotation speeds, torques and preci-sion. Nevertheless, the majority of allconverting techniques use the same, lim-ited number of basic mechatronic func-tions. The Converting Toolbox providesexactly these drive functions in line withthe specific requirements and in a finelyscalable setup.

Copy and Paste Engineering

The individual mechatronic functions canbe used directly in the user program in theform of function blocks. Enclosed demoapplications show how the required tech-nological function can be implementedefficiently and with high performance witha single function block. For example, adancer-controlled winder with individualcore hardness characteristics is ready to useafter minimum adaptations to the respec-tive machine hardware, and is equippedwith all the necessary operator interfaces.The machine function can be tested andoptimized in stand-alone mode, requiringonly a short set-up time. The relevant codeof the demo application, basically the FBcall with the interface to the operatinginterface, can simply be transferred to yourown project by Copy and Paste. Alterna-tively, a demo application can be easilyextended to full-scale application bymatching the individual machine func-

tions to a real or virtual control axis. Themotion control is therefore flexible andsupports a wide range of applications ofthe machine with short set-up times.

Platform choices

The Simotion motion control system is thepreferred system platform for the Con-verting Toolbox. With Simotion, con-troller-based topologies or IPC-aidedautomation are also available. There arefunction blocks for all Simotion hardwareplatforms and Simatic S7 control used with the latest Masterdrives MC convert-ers, which can be used on the respectiveplatforms without additional adapta-tions. This provides an exceptionallygood scalability in hardware and softwarethat accommodates for the wide variety ofwindable materials.

Standardized and open

The expenses for configuration throughcommissioning and documentation isreduced considerably by the standardizedsolutions compared to in-house develop-ment of new solution by the machine man-ufacturer: In more than 80 percent of allcases, the drive functionality required in a

machine module is fully covered by a com-ponent of the Converting Toolbox. Simpleparameterization of the component forautomation of a coiler or layer is normallyenough. However, if the standard func-tionality of a component still has to beextended or changed, the functions of theConverting Toolbox prove to be extremelyefficient even for implementing specialfunctions.

The independence of the machinemanufacturer and end user in diagnostics,modifications and adaptations, is guaran-teed by the openness of Siemens automa-tion systems. The end user of a machineautomated on the basis of the ConvertingToolbox also enjoys the benefits of theintegrated diagnosis, maintenance andservice functionality typical for TotallyIntegrated Automation.

31SERVICE & SUPPORT

To ensure that the costs for the machinemanufacturer (OEM) always remain

within the planned scope and therefore cal-culable, Siemens offers a Repair Service Con-tract (RSC). This contract offers the machinemanufacturer worldwide troubleshootingat a reasonable flat rate – even at the owner’splants. The RSC has a duration of 12 or 24months and offers the following services:provision of service personnel, error diag-nostics and troubleshooting on site as wellas a proof that the failure has been fixedsuccessfully.

The RSC is activated as soon as it is ac-knowledged that the machine has reachedits destination. This enables fast machine-specific procurement of spare parts withoutcomplicated pre-clarification between theend customer/OEM and Siemens in a serv-ice case – and that means only one certifi-cate number for the optimized machine serv-ice. The contract is managed in EUNAweb(End User Notification Administration viaWeb). EUNAweb is a database throughwhich equipment and RSC data are availableto authorized contract partners at any time.

Mechatronic Support

When an existing machine does not meet requirements or aproven machine is to be developed further, Mechatronic Sup-

port will help: A machine analysis first provides information of thedevelopment potential of a given machine concept. Together withSimulation and Virtual Prototyping, the analysis results can bequantified exactly. The customer can therefore look for the bestmachine solution as early as the development phase.

This is the ideal basis for a simulated machine model (changescan still be made to the design at this construction). The virtual pro-totype created on the computer already has all the characteris-tics of the real machine – there’s now nothing stopping series pro-duction. �
