handle any type of part from operation to operation. Overhead power-and- free conveyors offer flexibility to a manufacturing operation.

Besides, self-powered monorails independently drive trolleys that can run on the level or uphill. A master controller directs the trolleys in highly flexible configurations.

СVarious types of cranes can be employed to manoeuvre parts too heavy to lift manually, and this technology includes robots as well.

It is of importance to note that automated storage and retrieval systems (AS/RS) add more than control and space saving to a manufacturing operation. As flexible manufacturing systems increase their output and the variety of parts that will be produced in small lots, AS/RS fit the needs for buffer storage. Some new FMSs are being designed with raw stock being stored in AS/RS and delivered to machines by automatic guided vehicles. The AS/RS can also provide quick access to the jigs, fixtures and tooling

required by the FMS.

 

 

 

 

 

 

 

 

иMiniload automated storage and retrieval systems, along with hori-

zontal and vertical carousels, bring parts to the worker, often under com-

puter direction.

To sum it up, it is necessary to say that the user today is looking for

automatic materialбhandling system. He wants to be sure that a part can be

found when it is needed. Such system is automatic guided vehicles (AGVs)

which is beginning to take a significant role in material handling. The

guided vehicle usually carries the workpiece, on a machine pallet or fixture

base, from work cell to work cell. One can say that AVG is not only a

transporter of parts and tools, it is also a factory system for delivery, the

mode of transportation for the highly flexible systems.
