Abstract

A mechanical system is provided for processing workpieces, especially metal sheets. The system has a storage side with a workpiece store, a processing side with a plurality of mechanical processing units, and a mechanical feeding device which is provided between the storage side and the processing side. The feeding device comprises a plurality of feeding units, with different feeding units of the feeding devices being associated with different processing units. The feeding units are configured to pick up work pieces at the storage side and deliver them at the processing side to the respectively associated processing unit(s). In addition or as an alternative, the feeding units may pick up workpieces at the processing side from the respectively associated processing unit(s) and deliver the workpieces at the storage side.

Claims

1. A mechanical system for processing workpieces, the systems comprising:

a storage side, comprising a workpiece store with a plurality of storage units,

a processing side, comprising a plurality of mechanical processing units,

a mechanical feeding device, provided between the storage side and the processing side, which comprises a plurality of feeding units configured to move workpieces between the storage side and the processing side,

system modules, each system module comprising, in association with each other, one or more of the storage units of the workpiece store, one or more of the processing units of the processing side, and one or more of the feeding units of the feeding device, wherein the feeding units of the system modules are provided between associated storage units and processing units and are configured to move the workpieces between the storage side and the processing side of the relevant system module, and

a transfer device, disposed between the feeding units or storage units of different system modules, the transfer device being configured to transfer the workpieces to and/or from the feeding units and/or the storage units of the different system modules and being provided within the floor space area of the storage units of the system modules.

2. A mechanical system according to claim 1, wherein the transfer device is configured to transfer the workpieces between feeding units associated with different processing units and/or between storage units associated with different processing units.

3. A mechanical system according to claim 1, wherein the workpiece store is in the form of a rack storage system.

4. A mechanical system according to claim 3, wherein the storage units are in the form of rack units.

5. A mechanical system according to claim 1, wherein the feeding devices comprise rack storage and retrieval devices.

6. A mechanical system according to claim 1, wherein the transfer device comprises at least one transfer unit which is movable between the feeding units that are associated with different processing units with a transfer movement.

7. A mechanical system according to claim 6, wherein at least one transfer unit is movably guided on the workpiece store during the transfer movement.

8. A mechanical system according to claim 1, wherein the transfer device comprises at least one transfer unit which is movable between the storage units that are associated with different processing units with a transfer movement.

9. A mechanical system according to claim 8, wherein at least one transfer unit is movably guided on the workpiece store during the transfer movement.

10. A mechanical system according to claim 1, wherein the workpiece store is in the form of a pallet store.

11. The mechanical system according to claim 1, wherein the processing units are configured to process metal sheets.

12. A method for processing workpieces, the method comprising:

introducing a workpiece into a storage unit of a storage side of a system module of a processing system,

using a feeding unit of a mechanical feeding device, provided between the storage side and a processing side of the system module, to move the workpiece between the storage side and the processing side, and

using a transfer device, disposed between the system module and a second system module with a storage unit and being provided within the floor space area of the storage units of the system modules, to transfer the workpiece to a feeding unit and/or the storage unit of the second system module.

13. The method of claim 12, further comprising using the transfer device to transfer the workpiece from the processing side of the system module to the processing side of the second system module.

14. The method of claim 13, further comprising performing a first processing step at the processing side of the system module and a second processing step at the processing side of the second system module.

15. The method of claim 12, further comprising using the transfer device to move the workpiece to a position at which the workpiece can be removed from the processing system.

16. A mechanical system for processing workpieces, the system comprising:

a workpiece store with a plurality of storage units,

a plurality of mechanical processing units,

a mechanical feeding device, comprising a plurality of feeding units configured to move workpieces between the workpiece store and one or more of the processing units,

the storage units, mechanical processing units, and feeding units being associated with each other to define a plurality of system modules, each system module comprising one or more of the storage units of the workpiece store, one or more of the processing units of the processing side, and one or more of the feeding units of the feeding device, wherein, in each system module, at least one feeding unit is provided between an associated storage unit and an associated processing unit and is configured to move the workpieces between the associated storage unit and the associated processing unit, and

a transfer device, disposed between the system modules, the transfer device being configured to transfer the workpieces between the different system modules and being provided within the floor space area of the storage units of the system modules.
