An automated storage and retrieval system(ASRSor AS/RS) consists of a variety of computer-

controlled systems for automatically placing and retrieving loads from defined storage

locations.[1]Automated storage and retrieval systems (AS/RS) are typically used in applications where:

there is a very high volume of loads being moved into and out of storage; storage density is important

because of space constraints; no value adding content is present in this process; accuracy is criticalbecause of potential expensive damages to the load. AS/RS can be used with standard loads as well as

nonstandard loads.[2]

ASRS are also used in libraries allowing for greater safety when consulting and retrieving books.

AS/RS systems are designed for automated storage and retrieval of parts and items in manufacturing,

distribution, retail, wholesale and institutions. They first originated in the 1960s, initially focussing on

heavy pallet loads but with the evolution of the technology the handled loads have become smaller.[3]The

systems operate under computerized control, maintaining an inventory of stored items. Retrieval of itemsis accomplished by specifying the item type and quantity to be retrieved. The computer determines where

in the storage area the item can be retrieved from and schedules the retrieval. It directs the proper

automated storage and retrieval machine (SRM) to the location where the item is stored and directs the

machine to deposit the item at a location where it is to be picked up. A system of conveyors and or

automated guided vehicles is sometimes part of the AS/RS system. These take loads into and out of the

storage area and move them to the manufacturing floor or loading docks. To store items, the pallet or tray

is placed at an input station for the system, the information for inventory is entered into a computer

terminal and the AS/RS system moves the load to the storage area, determines a suitable location for the

item, and stores the load. As items are stored into or retrieved from the racks, the computer updates its

inventory accordingly.The benefits of an AS/RS system include reduced labor for transporting items into and out of inventory,

reduced inventory levels, more accurate tracking of inventory, and space savings. Items are often stored

more densely than in systems where items are stored and retrieved manually.[4]

Within the storage, items can be placed on trays or hang from bars, which are attached to chains/drives in

order to move up and down. The equipment required for an AS/RS include a storage & retrieval machine

(SRM) that is used for rapid storage and retrieval of material. SRMs are used to move loads vertically or

horizontally, and can also move laterally to place objects in the correct storage location.[5]

The trend towards Just In Time production often requires sub-pallet level availability of production inputs,

and AS/RS is a much faster way of organizing the storage of smaller items next to production lines.

Material Handling Institute of America (MHIA), the non-profit trade association for the material handlingworld, and its members have broken AS/RS into two primary segments: Fixed Aisle and

Carousels/Vertical Lift Modules (VLMs). Both sets of technologies provide automated storage and

retrieval for parts and items, but use different technologies. Each technology has its unique set of benefits

and disadvantages (like everything in the world). Fixed Aisle systems are characteristically larger systems

whereas carousels and Vertical Lift Modules are used individually or grouped, but in small to medium-

sized applications.

A fixed-aisle AS/R machine (stacker crane) is one of two main designs: single-masted or double masted.

Most are supported on a track and ceiling guided at the top by guide rails or channels to ensure accurate

vertical alignment, although some are suspended from the ceiling. The 'shuttles' that make up the system

travel between fixed storage shelves to deposit or retrieve a requested load (ranging from a single book ina library system to a several ton pallet of goods in a warehouse system). The entire unit moves

horizontally within an aisle, while the shuttles are able to elevate up to the necessary height to reach the

load, and can extend and retract to store or retrieve loads that are several positions deep in the shelving.

A semi-automated system can be achieved by utilizing only specialized shuttles within an existing rack

system.

Automated storage and retrieval system using the highly dynamic TGW Stingray shuttle technology.

Another AS/RS technology is known as shuttle technology. In this technology the horizontal movement is

made by independent shuttles each operating on one level of the rack while a lift at a fixed position within

the rack is responsible for the vertical movement.[6]By using two separate machines for these two axis

the shuttle technology is able to provide higher throughput rates than stacker cranes.[7]

Storage and Retrieval Machines pick up or drop off loads to the rest of the supporting transportationsystem at specific stations, where inbound and outbound loads are precisely positioned for proper

handling.

In addition, there are several types of Automated Storage & Retrieval Systems (AS/RS) devices called

Unit-load AS/RS, Mini-load AS/RS, Mid-Load AS/RS,[8]Vertical Lift Modules (VLMs), Horizontal Carousels

and Vertical Carousels. These systems are used either as stand-alone units or in integrated workstations

called pods or systems. These units are usually integrated with various types of pick to light systems and

use either a microprocessor controller for basic usage or inventory management software. These systems

are ideal for increasing space utilization up to 90%, productivity levels by 90%, accuracy to 99.9%+ levels

and throughput up to 750 lines per hour/per operator or more depending on the configuration of the

system.

Advantages[edit]

An effective automated storage and retrieval system provides several benefits forsupply chain

management:

An efficient AS/RS system helps companies cutexpensesby minimizing the amount of unnecessary

parts and products instorage,and improving organization of the contents of a warehouse. Due to

automated processes, it also allows for more storage space due to high-density storage, narrower

aisles, etc.[9]

Automation reduces labor costs while lowering workforce requirements and increasing safety.[10]

Modeling and managing the logical representation of the physical storage facilities (e.g. racking, etc.).

For example, if certain products are often sold together or are more popular than others, thoseproducts can be grouped together or placed near the delivery area to speed up the process of

picking, packing and shipping to customers.

Enabling a seamless link to order processing and logistics management in order to pick, pack, and

ship product out of the facility.

Tracking where products are stocked, which suppliers they come from, and the length of time they

are stored. By analysing such data, companies can control inventory levels and maximize the use of

warehouse space. Furthermore, firms are more prepared for the demands and supplies of the

market, especially during special circumstances such as a peak season on a particular month.

Through the reports generated by an AS/RS system, firms are also able to gather important data that

may be put in a model for it to be analyzed.[11]

Vertical lift module[edit]

VLMs can be built quite high to match the available overhead space in a facility. Multiple units can be

places in 'pods' whereby an operator can retrieve items from one unit while the other units are moving.

Variants include width, height, load, speed and a control system.[12]

The VLM is a board controlled automated vertical lift module. Inventory within the VLM is stored on front

and rear tray locations or rails. When a tray is requested, either by entering a tray number in the built in

control pad or by requesting a part through software, an extractor travels vertically between the two

columns of trays and pulls the requested tray from its location and brings it to an access point. The

operator then picks or replenishes stock and the tray is returned to its home upon confirmation.

VLM systems are sold in numerous configurations, which could be applied in different industries, logistics,

as well as office settings. The VLM systems could be customized to fully utilize the height of the facility,

even through multiple floors. With the capability of multiple access openings on different floors, the VLM

system is able to provide an innovative storage and retrieval solution. The rapid movement of the

extractor as well as inventory management software can dramatically increase the efficiency of the

picking process. This occurs by simultaneously retrieving and storing trays in multiple units. Unlike large

AS/RS systems, which require a complete overhaul of the warehouse or production line, the vertical lift

modules are modularized, which can be easily integrated into the existing system, or to be rolled out in

gradually over different phases.

Most common applications include: MRO, order picking, consolidation, kitting, parts handling, buffering,

inventory storage, WIP, buffer storage, and many more.

VLMs provide floor space savings, increased labor productivity, improved worker ergonomics, andcontrolled process.

Most VLMs offer dynamic space storage which measures the tray every time it is returned to the unit to

optimize space, safety features and some offer tilt tray delivery for increased ergonomic accessibility, and

laser pointers which indicate the exact item to be picked on each tray.

Horizontal carousels[edit]

A horizontal carousel is a series of bins which revolve on an oval track. Every bin has shelves which are

adjustable to .75" and can be configured for a myriad of standard and special applications. An operator

simply inputs a bin number, part number or cell location and the carousel will rotate via the shortest path.

Multiple horizontal carousels integrated with pick to light technology and inventory management software(a pod of carousels) are used for order fulfillment.

A wave of orders are sent to the pod. A group of orders are selected to create a batch. The operator

simply follows the lights and pick round robin from the carousels and place items in a batch station behind

them. Each carousel pre-positions and rotates when picked. By applying the "product to person" principle,

operators do not have to move from their position to prepare the order.

When the batch is complete, a new batch is inducted and the process repeated until the wave is

complete. Horizontal carousels can save up to 75% of floorspace, increase productivity by 2/3, accuracy

levels to 99.9%+ levels and throughput up to 750 lines per hour/operator.

Horizontal carousel systems generally outperform robotic systems for a fraction of the cost. Horizontalcarousels are the most cost effective AS/RS system available. [citation needed]

Robotic Inserter/Extractor devices can also be used for horizontal carousels. The robotic device is

positioned in the front or rear of up to three horizontal carousels tiered high. The robot grabs the tote

required in the order and often replenishes at the same time to speed up throughput. The tote(s) are then

delivered to conveyor which routes it to a work station for picking or replenishing. Up to eight transactions

per minute per unit can be done. Totes or containers up to 36" x 36" x 36" can be used in a system.

On a simplistic level, horizontal carousels are also often used as "rotating shelving." 'With simple "fetch"

command items are brought to the operator and otherwise wasted space is eliminated.

Installed applications[edit]

Installed applications of this technology can be wide ranging. In some libraries, such as at UNRlibrary,

such a system is employed to retrieve books. Still others in use involve retrieval of bicycles from a bicycle

tree,as in the case of systems in Japan.

Man-aboard systems[edit]

A man-aboard system can provide significant floorspace savings over manual or fork lift operations but is

not truly an AS/RS, as the operation is still manual. Storage system heights are not limited by the reach

height of the order picker, as the picker rides along on the platform as it is moved vertically or horizontally

to the various storage locations. Shelves or storage cabinets can be stacked as high as floor loading,

weight capacity, throughput requirements, and/or ceiling heights will permit. Man-aboard storage and

retrieval systems are far and away the most expensive picker-to-stock equipment alternative, but are less

expensive than a fully automated system. Aisle-captive storage/retrieval machines reaching heights up to

40 feet cost around $125,000. Hence, there must be enough storage density and/or productivityimprovement over cart and tote picking to justify the investment. Also, because vertical travel is slow

compared to horizontal travel, typical picking rates in man-aboard operations range between 40 and 250

lines per person-hour. The range is large because there is a wide variety of operating schemes for man-

aboard systems. Man-aboard systems are typically appropriate for slow-moving items where space is

fairly expensive.

The trend towards individualization has created a new challenge for intralogistics:batch sizes are becoming smaller,and articles are becoming available in more and more variants. This is having consequences for warehouse technology andequipment. Small containers are now used where large ones were formerly required. Whereas, for example, containersmeasuring 600 x 400 mm (23.6 x 15.6 in) used to be common, con tainers half this size are coming into increasing use.

To permit flexible handling of these containers in automated small parts storage facilities with mul tipledeep storage, viastorehas developed a new storage system for plastic containers and cartons.

Greater speed and flexibility in automated small parts storage facilities:

Containers measuring 600 x 400 mm (23.6 x 15.6 in) and 300 x 400 mm (11.8 x 15.8 in) can be handled in anycom bination desired

Thanks to a patented design of the conveyor system in the front zone, the storage and retrieval machine can workat full capacity

Goods can be stored without being presorted by storage unit size The retrieval machine has flexible access to each load unit, permitting the formation of series

Flexible: the new load handling device manages containers and cartons of different sizesalso in mixed operation

This reduces the number of AS/RS machine movements, among other advantages

Comparison of systems:The distance traveled by storage and retrieval machines differs depending on whether one uses systems with large 600 x400 (23.6 x 15.6 in) con tainers divided into modules or systems with small 300 x 400 mm (11.8 x 15.8 in) containers. Toretrieve four different articles, each system requires moving the same number of containers. But with the two to fourdeepstorage system only half as many AS/RS machine movements are re quired as with the twodeep system because of theload handling devices capacity.

The transfers required by the two to fourdeep system reduce the number of AS/RS machine movements as compared topure twodeep systems but lead to an overall improvement in performance in relation to individual containers.

The benefits for you:

Fewer container movements Increased performance per AS/RS machine You retrieve only what you really need No unproductive trips

Advantages of two to fourdeep storage:

Containers do not have to be divided into modules The quality of order picking is improved because only the right article is accessed

The front zone conveyor system is relieved of sorting tasks and unproductive container movements Trays for uniting pairs of small containers are not needed There are fewer AS/RS machine movements, which means longer maintenance intervals, less wear and greater

energy efficiency.

The new load handling device manages large and small containers in any desired combination

AS/RS systems transport, stage, retrieve, and report on every inventoryitem with up-to-the minute accuracy

Picture your day without cluttered aisles, excess inventory, lost or damaged products, inaccurate records,

endless searching, climbing, bending and frustration. Imagine a highly profitable operation that adds

value and decreases expense. That's the promise of automated storage and retrieval systems. Can it be

realized? Most definitely - when you choose the right partner.

A mini-load automatic storage and retrieval system handles loads that are typically contained in small

containers, cartons, or totes.

Why mini-load systems?

A mini-load system lets you store more material in less space, especially material in totes. It can alsohandle these totes with much more velocity than conventional static, manual methods. Despite that

speed, Mini-load systems tend to run quieter than other methods. It's designed for totes, trays, cartons

and small parts.

Unit load is the material handling term for any configuration of materials that allow it to be moved by

material handling equipment as a single unit. Typically, this means pallet loads, but can apply to

containerized loads.

AS/RS can improve every aspect of pallet handling operations

Faster, smoother and quieter:Handling pallets in a storage system can be daunting, but AS/RS allows

you to control many more aspects of the operation than manual systems.

It's also much quieter than comparable manual systems - often no louder than the typical office

environment.

Space savings vs. manual storagecan also be significant. The footprint of the system vs. that of a

comparable manual system can result in significant savings in floor space. Use of the vertical cube is also

a factor.

Easy programming and inventory control

STV's feature onboard microprocessor control with no complex programming functions. Simply define the

layout to the controller and it directs the STV where to go and what to do.

Flexible layout options

STV's give your flexibility using a straight or L-shaped layout, or as a single- or multi-vehicle continuous

loop. Standard modular components can be easily configured to meet a variety of building layout, space,

and performance requirements. What's more, several independent STV systems can be controlled using

the same controller, even on separate floors.

Ready for expansion

STV systems are designed to grow right along with you. As your operating volume increases, simply add

STV's to the system to increase capacity. You can also expand your STV layout using the existing

modular power supply and connecting new components to the existing track and input/output stations as

needed.

Efficient sortation

STV's can sort loads to different delivery stations without the complex conveyor intersections that can

hamper throughput. And because STV's are bi-directional, they can receive loads as well as deliver them.

Automated Guided Vehicles

AGVs offer a variety of flexible configurations for nearly any

material handling function

AGVs are automatically-programmed vehicles that drive to pre-planned points and perform pre-

programmed functions.

Basic AGV classifications include Tow Type (for pulling carts & trailers), Unit load, which are the type

listed in our performance reports above, which carry pallet or other container loads on decks, fork typethat utilize a fork or mast, commercial/office type, and heavy carrier type for huge, heavy loads.

Functions include navigation/guidance, routing, traffic management, load transfer, vehicle management,

and system management.

Guidance system may consist of a wire embedded in the floor, special tape, laser and optical system.

Most effective where highly repetitive tasks are performed over extended distances. The variety in

configurations of AGVs is endless, virtually any type of material handling equipment can be converted to

an AGV.
