Title of the invention

Arrangement of a conveyor system and storage system outside the machine level

The field of application of the invention

The invention relates to the arrangement of a conveyor systems and storage system parallel to the machine level for the promotion and storage of larger workpieces or transport containers in manufacturing systems.

^ Characteristic of the known technical solutions It is known to convey larger workpieces on the machine level. The promotion takes place according to known principles of action on taxiways, magnetic cushion with air systems and other technical equipment. The conveyors, the

20 also can be designed as Zuteileinrichtungen and memory lines lead in the operating level of the worker, which is ergonomic reasons favorable to the working level of the machines, past the individual machines. At a

2 211368

frequent changes of direction of the promotion of workpieces or transport containers according to the technological process, conveyor lines for buffering the workpieces on the individual machines are designed as storage sections. The 5-piece conveyor thus occupies a considerable proportion of the existing production area. In manufacturing facilities with many machines, a storage facility is required due to the wait in front of each machine. Are known storage facilities with conveyors

These were used in the form of a high-bay warehouse. This vertical storage device can be arranged centrally or decentrally to the processing system. In this case, the promotion of workpieces or transport containers from the high-bay warehouse to the machines in the Ma chine level.

15This means that only the machines in the immediate vicinity of the high-bay warehouse can be conveniently supplied with workpieces and disposed of, since otherwise additional transport paths between the individual machines or other surface-demanding conveyors must be provided.

20The aim of the invention

It is an object of the invention to carry out the promotion and partial storage of workpieces or transport containers outside the machine level

 This leads in particular to a considerable saving of space

25by elimination of workpiece conveyance and workpiece storage at the machine level, as well as a significant reduction in the throughput time by using the partial structure or flow structure. Here, the automation is possible up to an unnamed production as well as the production in

30 lower automation levels. The item conveying and item storage can be palletized or unpalettised for medium and large workpieces and for small workpieces in transport containers. Due to the concentrated machine arrangement, due to the

As a result of this, shorter delivery routes and thus resulting

2t136 8

shorter conveying times, which leads to an increase in the number of requesting games and to a reduction in the downtime of the machines,

Due to the displacement of the workpiece conveyor and workpiece storage outside the machine level, in particular above the machine level, the workpiece flow can be made more space-efficient. This makes it possible to build a fully automated production.

Explanation of the essence of the invention

1ODer of the invention is based on the object to promote the workpiece or the transport container from a machine for processing on another machine and store as needed. This is essentially achieved in that for each machine a vertical conveyor is arranged so that a

15korizontal extendable support arm of the vertical conveyor, which may be pivotally mounted, the workpiece or the transport container from the conveyor system and storage system promotes into the working space of the machine. This makes it possible, the workpiece in. The jig of the machine

20 and after machining on the machine in the conveying level outside the machine level, preferably above parallel to the machine level, due. Due to the grid-shaped arrangement of the conveyor system and storage system above the machine level, which the workpieces

25 or conveying transport containers on roller conveyors, roller conveyors, air-bearing systems, magnetic cushions or the like does the vertical conveyance of the workpieces lead through and does the transfer of the workpieces or transport containers to the conveyor system and the takeover of the »

3Obehälter from the conveyor system. After the transfer of the workpiece or the transport container on the conveyor system above the machine level, the allocation is made to the following according to the technological process downstream machine. Due to a waiting line, several or more workpieces are already being grounded

35Transport containers, which are intended for processing on this machine, stored in the conveying plane, so can a

Einspei rather ung in a further storage device, for example, high-bay warehouse, which may be connected to the storage and conveyor described, done on demand. Another way of taking over and transferring the factory-5 pieces or transport container from or to the storage and conveyor system is that the vertical conveyor promotes a releasable part of the conveyor track with the workpiece or transport container on or on the machine and the "machined workpiece or The transport and storage system is preferably arranged above an intermediate ceiling for reasons of occupational safety, better accessibility for repairs and work organization.

FIG. 1 shows an exemplary embodiment:
