2.1. General functions and applications, intended use The TITAN VK10 strapping head 0030-50 / 0030-51 is intended for installation into fully automatic strapping machines for plastic strap. There it works as a sturdy, reliable and maintenance-friendly central unit for the bundling, compiling and securing of packing items with kind and form being manifold. It is a quality product and is used successfully in many applications. The TITAN VK10 strapping head 0030-50 / 0030-51 is operated electrically or pneumatically and is wired completely to connectors ready for operation. Thus, it can be disassembled quickly for service and repair works as well as tests outside the machine. The drive exploiting three-phase AC motors allows very high flexibility in the control design, even for special applications. Each strapping head qualified in a complete function test and a high voltage test before delivery. The TITAN VK10 strapping head 0030-50 / 0030-51 meets German and European safety standards and complies with the provisions in the following EU directives:
Machine Directive 98/37/EG
Low-voltage Directive 73/23/EWG
EMVG Directive 89/336/EWG
2.2. Information on installation and use The TITAN VK10 strapping head is meant for the strapping of packing items. For reasons of safety it must not be used for a different purpose, e.g. for tensioning or compressing compressible packing items. For that purpose, machines with press beams have to be used.
Unintended use! Strapping material must not be used for the hoisting of loads; this strapping head may only be used as intended and specified above.
TITAN does not accept liability for injuries to persons or damage to objects caused by unintended use, e.g. incompetent handling, control errors, false operation etc.
The client must secure the strapping head such that unauthorized persons or untrained staff cannot get into the hazardous areas of the mobile machine components.

3. Safety instructions The warning and danger notes on the strapping head have to be observed precisely, all of them have to kept legible. In case of incompetent operation or unintended use risks to the user’s or a third party’s life and limb may occur; so can an impairment of the machinery or further assets of the user. The manufacturer / supplier cannot be held liable for resulting damage. The risk is exclusively up to the user. Last but not least, the efficient operation of the machine is under risk as well. Therefore each worker having to do with the erection, commissioning, operation, maintenance and servicing of the machine and working in the user’s factory must have read and understand the operating instructions.
3.1. Safety remarks and notes
When installing the strapping head the general regulations for the prevention of accidents (BGV A1) have to be observed.
The area of the strapping operations with plastic strap is a dangerous zone and
must be secured in compliance with EN 294!
Attention! All safety and warning notes must be followed in any case; we especially refer to the EU machine directives. When being installed the strapping head must be inspected according to EN 60204-1.
Protective installations, covers and linings of the head or the strapping machine must be inspected before the commissioning. They must neither be loose nor removed.
The operating staff must be instructed precisely before the first operation of the
strapping head and made familiar with the handling of the head. Unauthorised persons are not allowed to use the strapping head.
Neither persons nor objects must be found in the strapping range of the head
(machine) before any activation of the machine.
Before the beginning of cleaning works and/or troubleshooting the strapping head has to be disabled and secured against a restart. Turn main switch at position OFF.
Attention! During the strapping operation it is forbidden to grab into the channel area or below the packing item. Attention! Risk of squeezing.
B18K120-19B GB 50/07
VK10 K120-19B 8 / 45
When eliminating faulty strapping operations wear eye, face and hand protection. When cutting the strap hold the upper part firmly (see figure). Attention! The lower part jumps up.
Caution! Strap may tear when it is tensioned. Do not stand in the alignment of the strap!
Only use original TITAN spare parts! The use of spare parts not made by TITAN excludes guarantee and liability.
We cannot accept liability for unauthorised rearrangements of or alterations to the
strapping head! Further to that, guarantee/warranty expires and the operating instructions are no longer applicable.
Warning of hot parts:
A yellow and black sign (825) “Warning! Hot parts“ is attached near the sealing area on the channel element right (821) of the head channel. It warns of the risk by the hot heating E44 (526) and parts nearby being heated up potentially.
Caution! Do not expose heat-sensitive objects to the direct influential area of heat from the heating, e.g. on the covering plate (913), over a longer period. Do not allow explosive objects, dusts, liquids or gases to be taken to the area near the strapping head.
How to proceed in case of false strapping:
If there is no packing item in the strapping channel and a strapping operation is performed accidentally, the strap is placed around the matching plate (23).
Note! Before a restart take scissors and remove the strap from the matching from the matching plate (23) to avoid consequential damage (jamming of the matching roll due to additionally incoming strap).
For that purpose the strap should be cut approx. in the middle of the matching plate (23). Following that, take the left end of the strap standing upright above the covering plate (913), use your second hand to actuate the pushbutton “Touch control cam gear” S63 such that the cam gear performs a complete turning. While the matching plate is opened, pull the strap out of the sealing area.
B18K120-19B GB 50/07
VK10 K120-19B 9 / 45
Caution! Never grab into the head channel or the sealing mechanism, since there is the risk of squeezing by the release spring forces.
Information on the electric and pneumatic systems and the driving units: The cover of the empty housing (710) may only be opened by technical staff for electric systems. Generally, the machine must be disabled before the opening of the cover. Never remove the earth cable (green / yellow) from motors or other electrical components. After repair works especially pay attention to the re-attachment.
Attention! Always disconnect the compressed air network for mounting works and other interferences with the pneumatic system; never allow a connection to the medium. Attention! In automatic mode, e.g. in a modular plant, attention has to be paid that no shearing or squeezing points can occur between the feeding system (e.g. roller table) and the mobile machine / strapping head..
At this point, safety clearances according to DIN 31001 part 1 must be adhered to or the relevant safety precautions have to be implemented. The electrical and pneumatic equipment of the strapping head must be inspected and checked regularly. Defects like loose connections or scoured cables or hoses must be eliminated immediately.
3.2. Transport, storage, mounting Transport: The strapping head is transported by means of a hoisting gear. The load carrying capacity of the hoisting gear must at least be the weight of the TITAN VK10 strapping head 0030-50 / 0030-51 (see Technical data, section 4). To take up the head the girder (701) is provided with a large through bore-hole (see section 4.1) at its top, at which a commercial round sling or a round sling pendant can be used. The load hooks of the load carrying devices are suspended into this round sling and the strapping head is transported carefully. Take the position of the centre of gravity into account to prevent tilting when the load is deposited or going into reverse when it is lifted.
B18K120-19B GB 47/16
VK10 K120-19B 10 / 45
Attention! Do not stay under the load when it is deposited or lifted. Ask people standing around to leave the area. Minimum load carrying capacity 100 kg.
Storage: Before its final installation the strapping head should be stored in dry rooms at temperatures of between +5 to +50 °C. There, the strapping head should be protected against rough environmental pollution, e.g. by covering with corrugated cardboard which does not exclude the ventilation of the strapping head (rel. air humidity max. 60 %).
Note! If the machine is deactivated over a longer period, bearings, gear units and shafts can corrode at the points of contact especially quickly or be exposed to humidity in a different way. Therefore, use a desiccant with humidity indication acc. to DIN 55273. If that is impossible, all mobile parts of the machine should be moved once per week.
Mounting: The mechanical connection of the strapping head with the machine is effected on the fitting surface of the tie bar (153) by means of four M12-bolts. Electric power and compressed air are provided with detachable screwing connectors or quick-acting couplings. After the loosening of the four bolts and the decoupling of electric power and compressed air the head can be replaced easily and without problems. Waste disposal:
Should packing material have to be disposed of, admit it to the relevant recycling container or the Dual System.
Should the strapping head have to be disposed of at the end of its life, isolate plastic material, steel and aluminium and dispose of them separately. Further to that, the motors and electrical assemblies like control system, switches and cables must be admitted to separate waste disposal. Hand them to the relevant point of waste.
Observe the country-specific regulations on waste disposal.

Note! When using a frequency converter connect it to 230 V, use a separately shielded cable and operate it in 87-Hz technique.
Information on noise: The working place related noise emission value is below 85 dB(A). However, it has to be observed that noise emissions of a strapping machine mainly depend on the operating conditions. Factors for that are e.g. different speeds, the kind of place of erection, kind of floor, kind of and clearance to the ceiling, different materials to be processed.

5. Arrangement and descriptions
5.1. Main units The VK10 mainly comprises the following functional groups: A: Transport and tension unit:
The transport and tension unit conveys the strap through the strap channel connected back to the strapping head, where it actuates the strap stop switch. During conveyance back the strap is positioned narrowly around the packing item and tensioned in compliance with the tension time preset.
B: Sealing unit:
The sealing unit is a unit controlled via the cam gear (indexing control). It clamps the ends of strap, cuts the strap and forms the seal by means of the heating.
C: Heating:
The electrically operated resistance heating makes the quantity of heat required available to form the seal. For that purpose the heater tongue immerses between the straps and heats them up in the area of the sealing point.
D: Strap guide / head attachments:
The strap guides are the connection between strapping head and strap channel through which the strapping head is conveyed around the packing item.

6. Commissioning of the strapping head After the installation of the strapping head into the strapping machine the following items must be taken into account before the commissioning:
Thermal contacts of the electric motors must be integrated into the safety chain of the electric control system (PLC).
Due to the ventilation of the motors the strapping head must not be encapsulated.
An axial minimum clearance of 20 mm to the shrouds must be adhered to.
Check the electrical feed to the different electrical ports (see section 4 “Technical data“).
Check the correct sense of rotation of the motors; change phases, if required, to have the proper running directions at the transport wheel (204) and tension wheel (1178) (see figure section 8.6).
Check the function of the operating elements, timers and inductive limit switches.
Check the zero position of the cam gear and adjust it, if required (see section 7.1 “Home position, 0-degree position“).
Perform a high-voltage check according to DIN EN 60204 or VDE 0113.
When the main switch has been enabled, the heating E44 (526) is heated up and reaches the operating temperature of approx. 500 °C after approx. 5 minutes.
The strap must have been inserted properly into the strapping head (see section 8.9 “Insertion of strap“).
Note! The list cannot be complete. Further checks perhaps in compliance with additional instructions or plant-specific situations.

7.1. Home position, 0-degree position As described in section 8.9 the strap has been inserted into the strapping head. With button S63 “Touch control cam gear“ being actuated permanently the strapping head is moved to home position. Control vane 3 (1078) has been assigned to cam gear switch B81: Dies 1 (500), 2 (501) and 3 (502) are found at their lower positions or have been retracted, separator (1) and matching plate (23) are at retracted position, the heating (526) has been extended. Strap guides are closed.
7.2. Functional process
The strapping head is at home position.
Filling the channel: When the strapping cycle is started the strap is conveyed through the strap channel of the strapping machine. The transport motor M22 drives the transport wheel (204), against which the non-driven matching roll (570) is pressed. When the strap gets back to the strapping head via the right channel element (821), the strap feed stop switch B82 is actuated by the actuating lever (1110) and the strap feed is stopped.
Note! During the strap feed the control timer t3 is active. When this timer expires without any assignment of switch B82 the control system indicates a fault with the strap feed.
Clamping / centring strap, 60-degree position: By the short-time actuation of the button S63 “Touch control cam gear” the strapping head is moved to the 1st indexing position. The indexing switch B84 is switched by the indexing disk at position K and thus defines the 60° position.

Clamping / centring strap, 60-degree position: By the short-time actuation of the button S63 “Touch control cam gear” the strapping head is moved to the 1st indexing position. The indexing switch B84 is switched by the indexing disk at position K and thus defines the 60° position. The centring fingers of the slide guide (250) centre the strap. Die 1 (500) clamps the end of strap which has returned into the head between head of die (1295) and matching plate (23). The beginning of strap is secured against being pulled back. In most cases of strapping operation that position is chose as the stand-by position. From that position the strapping head can be guided to the packing item. The channel elements (821 and 873) on the strapping head are opened.
Note! After a troubleshooting operation the stand-by position can be approached by the long pressing of the button S62 “Strap feed“.
Return motion / tensioning:
The electric control then switches the transport motor M22 back to strap return motion. The transport motor retracts the wheel via the transport wheel (204) quickly until the packing item has been entwined and the tension wheel (1178) is pulled onto the matching roll (570). When the matching roll (570) is reached a signal is transmitted to the electric control system via the strap tension switch B83. Tension timer t2 starts to be effective. That timer can be used to set the tension force in the strap (strap tension) stronger or weaker.

Formation of seal:
After the expiry of tension timer t2 the strap transport motor is disabled and the cam gear motor M26 is enabled by the electric control. Die 2 (501) then clamps the strap tensioned and the sense of rotation of the transport motors M22 is reversed for a short time by the expiry of timer t7 to obtain a tension-free cutting operation (reversing). That position is defined as the 80-degree position in the optionally obtainable control of the control vane of the cam gear. Upon the expiry of the timer t9 the cam gear stops at that position. The indexing disk is without a cam for that position. Depending on the strap tension required it can happen that the cam gear stops at the 80°-position for a short moment to perform the reversing operation. Configuration with or without stop at 80° is implemented via the control system. The heating (526) is retracted. Die 3 (502) cuts the strap and, following that, presses the two ends, together with the heating (526), against the matching roll (23). Thus, the surface-fusion of the opposite strap inside surfaces is effected. After the extension of the heating (526) the surface-fused ends of strap are again pressed by die 3 (502) against the matching plate (23). Cooling position, 212-degree position: The shorttime actuation of button S63 “Touch control cam gear“ makes the strapping head move to the 2nd indexing position. The indexing switch B84 is switched by the indexing disk at position W and thus defines the 212°-position. For cooling down the cam gear stops at the cooling position, proximity switch B84 is assigned and maintains the pressing of the ends of strap, until the cooling timer t1 has expired. Therefore, the ends of strap being surface fused inside are sealed. Upon the expiry of the cooling timer t1 the restart of the cam gear motor M26 results in the lifting of die 1 (500), die 2 (561), die 3 (502) as well as the centring fingers of the slide guide (250).

Matching plate opened, 311-degree position:
The short-time actuation of the button “Touch control cam gear” makes the strapping head move to the 3rd indexing position. The indexing switch B84 is switched by the indexing disk at position F and thus defines the 311°-position. At that position the matching plate (23) opens and the completed strapping is released. After the reaching of the position Head before packing item B85 the head channel and the matching plate are closed again; the separator (1) is retracted. The cam gear switch B81 disables the cam gear motorM26 when reaching the zero position. In the optionally obtainable cam gear control the cam gear is stopped by the timer t8 at the 311°-position.

8. Operation and settings
8.1. General information The VK10 strapping head is set at the strap dimensions prespecified by the customer. When the dimension is altered, the following setting instructions have to be followed. The handling of the individual functions of the electric control system is described in the documentation on the electric system.
8.2. Setting the limit switches The TITAN VK10 strapping head is equipped with inductive proximity switches which react to all ferromagnetic metals entering the electromagnetic field originating from the button.
The button is identified by two circles.
The nominal clearance is 2 mm. Cam gear switch B81 and indexing switch B84: The cam gear switch and the indexing switch are found on the rear of the strapping head. They are accessible after the loosening of the cheese-head screw (242) and hexagon nuts (259) and the removal of the lining (233). The working clearance Sa of the control vane 3 (1078) or cam (1076) to the proximity switches B81 and B84 is to have the dimension 0.7 to 1.0 mm.
For that purpose loosen the cheese-head screw (1072) and sensitively turn the switch plate (1070) in the direction of the control vane.
Following that, tighten the cheese-
head screw again.
Reattach lining (233) to the indexing control.

VK10 K120-19B 25 / 45
Strap tension, strap tension switch B83:
Strap tension is applied by having the transport motor M22 tensioned for the predefined period t2 after the retraction of the strap from the channel system. For that purpose, an alterable tension time t2 must be provided in the electric control system. It can be set on the operator panel. The strap tension switch B83 (21) is found in the switch clip (238) in the top right corner of the housing (220). The clearance between the button of the strap tension switch to the switching element of the clamping bridge (307) is set as follows:
Loosen switch clip (238) and shift it within the longitudinal holes until the front edge of the switching element Lb is approx. 2 mm before the outer circle of the button of the strap tension switch B83.
The lateral gap Sb between the switching element of the clamping bridge and the button of the strap tension switch should be between 0.2 and 0.5 mm.
Note! Before the setting of the strap tension switch B83 (21) the transport and tension system must be set as described in section 8.6.

Strap feed stop switch B82:
The strap feed stop switch B82 is in the separator holder (1) behind the cover (85) at the top left corner of the housing (220). The strap feed stop switch disables the transport motor M22, when - after the strap feed into the channel system - the strap reaches the switching lever (20) and has swivelled against the matching plate (23). In this situation the head surface of the countersunk screw (18) dampens the switching zone of the strap feed stop switch B82. The switch is positioned on the cast pins of the separator holder (1). It is retained by the cover (85) being clipped and screwed with the PT bolt (86). The switching clearance between the strap feed stop switch and the head of the countersunk screw (18) in the switching lever (20) can – if required – be set by turning the countersunk screw. In that case the gap Ss between the button of the strap feed stop switch B82 and the head surface of the countersunk screw (18) should be between 0.5 to 0.8 mm at the end position switched by the strap.
Note! To guarantee an ensured switching function we recommend that the surroundings of the switch, especially at matching plate 6 (23) and die 2 (501) are cleaned frequently.

8.3. Setting the cam gear The setting of the zero(0)-position of the cam gear is effected via the control vane 3 (1078). The cam gear is turned by “TOUCH CONTROL” via the cam gear pushbutton S63 until the strap guide (821) and the channel element (873) have been closed. Then the control vane 3 on the shaft of the cam gear motor can be set for switch B81 (see section 7.1). The proper 0-position is checked by the subsequent permanent actuation of the pushbutton. The proper 0-position comprises:
The head channel (873 or 821) is closed firmly.
The slide guide (250) moved to a minimum in the direction of the centring position.
Repeat this operation until the proper 0-position has been reached.
Excess length Lh of the heater tongue: To make the heating E44 (526) move between the ends of strap only as far as necessary, the maximum entry stroke is limited by a stop of the heater tongue lever (66). The stop is reached by the hexagon bolt (192) in the heater tongue lever (66) which by its end of thread gets into contact with the housing (220) on the back of the running surface of the die. The hexagon bolt (192) has to set such that the front end of the heating E44 exceeds the front strap side edge of the strap in die I (500) by an excess length Lh = 2.5 to 3 mm. The following works are performed: Unscrew lining (945) and covering plate rear
(913) on the strapping head. Then dismount the matching plate (23) and
the bar left (529). The heating E44 is taken to the 80-degree
position (surface-fusion or reversing stop) by the pressing of the cam gear pushbutton S63.
Manually swing back the heater tongue lever (66) and secure it by means of suitable spacers.
Setting is performed by the loosening of the hexagon nut (194) at the hexagon bolt (192) and turning, until the exceeding dimension of the screw of approx. 25 mm has been reached.
Then the hexagon nut must be secured against the spring washer (193) and the excess length Lh has to be checked.
B18K120-19B GB 50/07
VK10 K120-19B 28 / 45
8.4. Setting the strap width To have the ends of strap in the sealing area positioned to each other as accurately as possible, a strap alignment (centring) has been installed in the VK10 strapping head which is set according to the strap width used. Pre-centring of strap: The marshal 3 (843) pre-centres the strap. Setting is implemented on the basis of the formula below. When the cheese-head screw (844) in the strap guide right (860) is loosened, the marshal 3 at the head channel can be set at the required setting dimension Xe. Following that, tighten the cheese-head screw (844) again. The setting dimension Xe of the marshal 3 should – depending on the maximum strap width Xbmax - be set at:
Xe = Xbmax + 2 mm .
In case of strap with strong sabre (lateral curvature) an enlargement can be reasonable. However, attention has to be paid that the strap feed stop switch B82 is assigned safely.
B18K120-19B GB 50/07
VK10 K120-19B 29 / 45
Note! The maximum strap width Xbmax is composed of the nominal strap width Xb (e.g. 19 mm) plus the upper strap width tolerance (e.g. 0.2 mm). For that purpose, strap width tolerances must be known.
Strap centring: The centring of the strap is implemented via the centring fingers at the slide guide (250). The centring fingers slip upper and lower straps onto the opposite guiding wall of the strap guide (890) as well as the control element (876). The strap ranges involved are aligned to one another. The centring fingers must not clamp the strap to allow the faultless retraction and tensioning of the strap after the centring. Therefore the setting dimension of the passage width at the centring fingers Xz is set at:
Xz = Xbmax + 0.3 mm
Take the slide guide (250) to the centring position by the actuation of the pushbutton S63 “Touch control cam gear”. At that position the clearance between the slide guide and guide wall is a minimum. Loosen hexagon nut (236) and set the centring fingers at the setting dimension Xz for the strap top be used turning the knurled screw head (235). Retighten hexagon nut (236). Setting the return stroke of the slide guide: Dimension Lz defines how far the slide guide (250) at the zero position of the cam gear is taken away by the heating E44 (526) and thus is removed from the die area. The dimension Lz should be set such that the front edges of the centring fingers are almost in line with the back edge of the dies. That is required to prevent the beginning of strap just coming out of the channel element right (860) does not run against the left centring finger. Setting is effected by the loosening of the hexagon nut (236) at the hexagon bolt (234) and its turning until dimension Lz is reached. A good value is approx. Lz = 10 mm. Then retighten the hexagon nut (236).
Attention! The hexagon bolt (234) may only be unscrewed as long as the clearance Sz at the zero position of the cam gear always exceeds 0. When the hexagon bolt (234) has been unscrewed too much, the tension pin (69) or the cam roller (68) at the heater tongue lever (66) may be destroyed!
B18K120-19B GB 50/07
VK10 K120-19B 30 / 45
8.5. Setting the sealing temperature The VK10 sealing system comprises two transformers, a power transformer in the electric control system and a sealing transformer at the strapping head. For the surface-fusioning of the straps an electronically controlled heating (526) with a meander-type sealing tongue is used. Two power circuits supply the sealing tongue with a low voltage of approx. 1.25 V and different currents generating two temperature ranges. The surface-fusion temperature TA (basic temperature) of the heating tongue is set on the operator panel of the electric control system.
For TITAN straps approx. 450 to 500 °C. To allow the transfer of just very little sealing material from the previous sealing operation to the subsequent one the sealing tongue surface is polished. Just a thin film remains on the tongue. After eight sealing operations consecutively the film is built up so strongly that the cleaning of the tongue is required. Thanks to a high cleaning current (≥ 6.0 A) this deposit is burnt without residues in a cleaning time twc of approx. 10 to 30 seconds.
Note! In case of a newly polished tongue that process is completed in 10 s. This, however, should hide the fact that the roughness of the tongue deteriorates slightly in the course of a longer operating time, which requires that the cleaning time is therefore extended.
The cleaning temperature TC (cleaning temperature) of the heating tongue is set on the operator panel of the electric control system.
For all TITAN straps approx. 580 °C.
Note! The above setting values refer to the ambient temperature of 20 °C. In case of higher deviations or additional effects of moving air the relevant values have to be adapted, if required.

8.6. Setting the strap thickness The transport and tension system of the VK10 must be set at the strap thickness used. The following information has to be observed.
Attention! The zero position of the cam gear must be set correctly before the adjustment of the transport and tension unit (see section 8.3).
Basic setting of gaps Sc, Sd and Sk:
The hexagon bolt (1093) is used for the basic setting of gap Sc between the transport wheel (204) and the matching roll (570) for strap feed and strap return motion. During that setting the transport ferrule or the short-stroke cylinder (1091) must be pressed. The clearance of gap Sc must be between 0.3…0.6 mm. Move a feeler gauge of the thickness of gap Sc between transport wheel (204) and matching roll (570). When ventilating the rocker (518) the matching roll (570) must not collide with the cylinder (1091). The hexagon bolt (432) must be set such that a clearance of approx. 2 mm occurs between matching roll and cylinder. The hexagon bolt (226) is used to implement the basic setting of the gap Sd between the matching roll (570) and tension wheel (1178); during that setting the rest of the strap must have been inserted into gap Sc. The following works must be performed:
B18K120-19B GB 50/07
VK10 K120-19B 32 / 45
1106
Loosening of the hexagon nut (223) and turning the hexagon bolt (226) against
the clamping bridge (307), until the dimension for the gap:
Sd = strap thickness + 0.2 mm
has been achieved. Tighten hexagon nut (223) again.
During the basic setting the minimum gap Sk between the tension wheel (1178)
and the matching roll (570) is set at
Sk = strap thickness – 0.3…0.5 mm
by means of the threaded pin (317). A rest of the strap must have been inserted into the gap Sc to allow the rocker (518) to be supported by the head of the hexagon bolt (1093).
The following works are performed:
Loosening the hexagon nut (318) and turning the threaded pin (317), slightly into the clamping bridge (307).
Manually move the clamping bridge (307) against the tension spring force (227) to the wall of the housing (220), until the tension wheel (1178) gets into contact with the matching roll (570).
Slip a feeler gauge with the thickness of the calculated gap Sk between the tension wheel (1178) and matching roll (570).
Following that, unscrew the threaded pin (317) out of the clamping bridge until its tip gets into contact with the wall of the housing (220) and the feeler gauge is released.
Screw the hexagon nut (318) again.
Note! When screwing the hexagon nuts (1094, 223 and 318) the settings prespecified may alter. There the subsequent check of Sc, Sd and Sk is recommended. After each basic setting of the gaps Sc, Sd and Sk the proper setting of strap tension switch B83 has to be checked; if required, it has to be readjusted.
Setting the frictional force in the conveying system: The frictional force must be adapted to the different facts like kind of strap, rigidity of strap, strap surface, channel size, channel friction and the discharging force of the strap, either from an accumulator or from an uncoiler. Setting is implemented by means of the knurled screw on the pressure control valve (1106). Turning it ccw increases the basic frictional force.

8.7. Setting the dies
The dies are set differently depending on the thickness of strap. Before the installation the dies are preset at the lengths L1 to L3 (see table below).
When being installed the gaps S1 to S3 are checked; they are corrected, if
required. Check the gaps at the 212°-position of the cam gear! The short-time actuation of pushbutton S63 “Touch control cam gear“ makes the strapping head move to the 2nd indexing position (cooling position or pos. W).

To set the die 3 (502), for example, the threaded pin (129) and the roll (128) are
dismounted; the security cage (506) is removed.
Turn the hexagon bolt (101) clockwise shortens the length of die; it is extended by turning the bolt ccw.
After the setting the hexagon bolt (101) is fixed by the security cage (506) as
shown in the figure.
Note! Disk springs (102) lubricated. Area Hsmax filled with grease. Pay attention to positional angle Als of the security cage (506) approx. 30°!
Number and layering of the disk springs: The disk springs are layered in opposite sense in packages of 2 springs or 3 springs each. The number of disk springs and the kind of layering have to be adhered to precisely, since otherwise faults may occur. Just disk springs built by TITAN may be installed, since third parties’ disk springs may have different force-path characteristics.

Dismounting and mounting dies 1 to 3:
Attention! The strapping unit must be disconnected from the power mains before any setting works are begun.
Unscrew the covering plates (905, 913) and the protective plate front (930) on the strapping head.
Manually swing matching plate 6
(23) and head channels (873, 821) open and secure them by appropriate spacers.
Remove the screw plugs (96, 1305)
being visible from above and the underlying pressure springs (83, 1189).
Unscrew pins (95) and push out the
relevant die towards the top.
Attention! The functional surfaces of the dies and the die guide (78) must not be damaged.
Installation is performed in the
reverse order with attention having to be paid that dies must be able to move in the die guide (78) easily and without jamming.
Note! To insert the dies into the die guide easily put the relevant die on a clean, level support and align head and foot of die to each other by slight hits with a plastic hammer.
Setting of the dies 1 and 2: After the installation of the dies the clearance between matching plate 6 (23) and dies 1 and 2 at cooling position (pos. W) must be checked by means of a feeler gauge. If the dimension for gap S1 or S2 is below 0.3 mm or above 0.5 mm, fine adjustment is required after the dismounting of the die.

For that purpose dismount dowel pin
(104) and roller (103) and remove the security cage (506) from the hexagon of the screw (101).
Screw in the screw (101) in case of a dimension below 0.3 mm or unscrew it in case of a dimension above 0.5 mm. A ¼ revolution of the screw (101) corresponds to an alteration to length of 0.2 mm.
Plug the security cage (506) onto the hexagon of the screw (101) such that the vanes of the security cage apply to the slot sides of the die foot (100) counter clockwise.
Following that, reinstall the roller (103) including dowel pin (104).
Install dies and check the clearance between matching plate 6 (23) and die.
Note! The precise dimension is attuned only after some actuations of the strapping head.
Setting the die 3:
After the installation of the die take a feeler gauge and check the clearance between the matching plate (23) and the die 3 at cooling position. If the dimension for S3 is below 0.8 mm or above 1.65 mm, fine adjustment is required.
For that purpose dismount dowel pin (129) and roller (128) and remove the security cage (506) from the hexagon of the screw (101).
Screw in the screw (101) in case of a dimension below 0.8 mm or unscrew it in case of a dimension above 1.65 mm. A ¼ revolution of the screw (101) corresponds to an alteration to length of 0.2 mm.
Plug the security cage (506) onto the hexagon of the screw (101) such that the vanes of the security cage apply to the slot sides of the die housing (127) counter clockwise.

Following that, reinstall the roller (128) including dowel pin (129).
Install the die 3 and check the gap S3 between die and matching plate, as shown in the above figure.
Note! The precise dimension is attuned only after some actuations of the strapping head.
8.8. Setting the cutter When the machine is used for a longer time, the cutting gap between the cutter (125) and the die head 1 (505) ca be enlarged due to wear. Therefore, the faultless cutting of the strap can no longer be guaranteed. Setting may also be required when the cutter (125) is replaced or strapping material of a thickness of 0.7 mm is used to compensate for inevitable manufacturing tolerances. A cutting gap being too large can be seen with one strapping at a notched or broken strap cutting edge. To compensate for the cutting gap which may max. be 0.05 mm to 0.07 mm one or several compensating plates 3 (131) are provided, if required. The compensating plate 3 (131) is 0.05 mm thick. It is installed between the die head 3 (120) and the cutter. Dismounting and mounting compensating sheet 3: For that purpose dismount the matching plate (23) at the sealing unit.
Dismount die 3 (502) as described in section 8.7.
Detach the cheese-head screws (124), remove the cutter.
Place compensating plate(s) 3 (131) beneath.
Screw cutter (125); hereby, the cheese-head screws (124) need not be tightened too firmly, since otherwise there is the risk that the cutter breaks.
Mount die 3 (502) again, and pay attention that it can be slipped into the die guide (78) easily and without jamming.

8.9. Insertion of strap (fading in) First, the pushbutton on the machine is actuated to lift the strap clamp outside the strapping head. Before the insertion of strap into the TITAN VK10 strapping head attention must be paid that the beginning of the strap is cut neatly and straightly. Then, the beginning of the strap is put in the strap insertion of the strap intake (519), until the resistance of the transport wheel (204) and the matching roller (570) can be felt. After the opening of the manual sliding valve (1109) the strap can be inserted further. Following that, the valve is pressed back, the rocker (518) is actuated and clamps the strap between the transport wheel and the matching roller. The strap clamp mounted outside closes when the pushbutton is pressed again or the cam gear is actuated. Then the TITAN VK10 strapping head is ready for the strap feed.

9. Maintenance
9.1. General servicing of the strapping head
The permanent readiness for operation by the VK 10 strapping head is achieved by regular and careful maintenance.
Always keep the strapping head clean.
Especially strap guides, the sealing area and spur gears in the transport and
tension area must be kept free from impurities and foreign substances.
9.2. Cleaning Clean the strapping head once a week – or more frequently, if required due to impurities by environmental influences. In doing so, remove ambient dust and the abrasion of the plastic strap from strap guides and especially the sealing area. In case of air-cleaning attention has to be paid that the blowing pressure used is as low as possible. The blowing direction must be chosen such that – if possible – no dirt particles get into contact with the hot heater tongue (1145) and into the guides, especially the die guide (78).
Attention! Pay attention to your own protection (wear protective glasses) and that of others being near by.
Attention! The strapping head must be disconnected electrically before cleaning works, repairs, maintenance and/or troubleshooting.
For that purpose, actuate the TOUCH CONTROL button S63 such that the cam gear is gradually switched further, until the matching plate 6 (23) is swung back and releases die 1 (500) to die 3 (502). Then actuate the OFF key of the electric control system, open the protective plate front (930) and clean the overall area. Remove insistent incrustations on dies 1 and 2 by means of a fine wire brush.
Attention! During these works attention has to be paid that contact with the heating (526) is avoided. The heater tongue maintains its operating state even when the OFF key has been actuated and is therefore very hot.
A polluted heater tongue results in bad strap seals.

Cleaning the heater tongue -E44:
When the electric control system is designed and set as required, the heating E44 (526) is cleaned by a high cleaning current during eight consecutive strapping operations. Melting residues from the previous strapping operation change to the vaporisation phase. In case of a faulty strapping and the subsequent troubleshooting it may occur that larger strap residues stick to the heating; they are skimmed off the heater tongue carefully by means of a cut of strap.
Caution! The surface-fused strap residues are hot and can drip. Do not let strap residues get into the running areas of the heating in the slide guide (250) or in other functional areas. Attention! The melting area of the heating, the heater tongue, must not be scratched or bent. Just a smooth, level heater tongue guarantees seals of high and constant stability.
Sometimes it is sufficient to perform a test strapping during which the remaining little strap residues are skimmed off the heater tongue. After each fault the heating and the entire die area must be checked for cleanliness and proper sealing. A monthly inspection of the heating is recommended.
9.3. Notes on lubrication All sliding areas – except for self-lubricating DU bushings and DU disks - are lubricated between the components with commercial roller bearing grease. They e.g. include: Cam rollers, plain rollers, running surfaces of the cam disk 1 (56), cam disk 2 (58), the cam lever (509), die, die guide areas, needle bushings, needle free run, disk springs in the dies, security cages (506) in the dies, cogging of the gears. Especially the lubrication on the running surfaces of the cam disks, of the cam levers and the cogging of the gears must be checked monthly. If required, missing lubricant must be replaced. The running surfaces of the dies on the housing (220) are treated with a thin teflon spray film during the assembly. The screw gear, all ball bearings – and this includes those in the motors – are lubricated for life.
Note! If a lot of dirt occurs in the surroundings of the strapping head, it can be advantageous to use commercial light spray oil for the surfaces being sensitive to dirt for subsequent lubrications.
When spray oil is used, a check of the lubrication is recommended at intervals of 2 weeks.

VK10 K120-19B 41 / 45
Attention! The sealing zones of the heating (526), the Vulkolan coating of the matching roller (570) and the running surface of the transport wheel (204) for the strap must not get into contact with the lubricants.

FAULT CAUSE REMEDY
Strap is not sealed or sealed insufficiently.
Heating (526) is defective. Replace heating (526).
Power supply at the heater tongue loose or broken (slack joint or short circuit).
Fasten cable or replace heater tongue (1145). Attention! The feeder of highly flexible cable must be freely accessible.
Temperature at the heater tongue too low.
Set temperature for different strap qualities.
Die 3 (502) has not been set properly or is defective.
Check die 3 (502); if required, replace disk springs and / or set the die anew.
After the replacement of the tension springs (43) a cam lever (509) does not return to its initial position on cam disk 1 (56) after a strapping operation. The sealing mechanism is blocked.
Cheese-head screw (425) or (430) was screwed too far into the safety nut (426) and is in frictional contact with the running surface of the die on the housing (220).
Loosen the cheese-head screws (1032) on the matching plate 6 (23). Loosen the blocking of the die concerned by lateral pressure against the cam lever in the direction of the shaft (47). Then unscrew the cheese-head screw (425 or 430) in the cam lever by approx. one revolution.
10.1. Restart of the machine after troubleshooting If the strapping cycle was interrupted (fault) or the OFF button was actuated, the machine must be enabled again after the troubleshooting at the zero position of the cam gear. For that purpose, it has to be ensured that all linings are mounted and all safety functions work. If the strapping head was switched completely idle for the troubleshooting, the heating-up time (approx. 5 minutes) of the heating (526) has to be awaited after the activation of the main switch. 1. Enable main switch (the heating is supplied with electric power). 2. If required, move the cam gear to zero position (keep TOUCH CONTROL button
S63 pressed). 3. Remove strap being cut. 4. Actuate START button on the operator panel (intake of strap). 5. If required, await heating-up period of the heating. 6. Actuate START button again (start of the strapping cycle) or (A). 7. For further strapping operations just actuate the START button or (A).
Note! (A) In case of fully automatic strapping plants with concatenated transport the system switches to automatic mode at that point. The strapping head then receives its start signal from the transport system, when the packing item is at strapping position.
