Abstract

A method for operating a production plant having an unmanned transport system involves transporting a first parts carrier having a plurality of parts from a warehouse to a picking station by at least one industrial truck. At least one part, which is predetermined according to a parts list, is extracted from the parts carrier using a worker and deposition of the part on a further parts carrier. The further parts carrier is transported to a work station by a further industrial truck.

Claims

1-9. -9. (canceled)

10. A method to operate a production plant having an unmanned transport system, which comprises a plurality of industrial trucks configured to receive control instructions from a control device, the method comprising:

transporting, by a first one of the plurality of industrial trucks, a first parts carrier having a plurality of parts from a warehouse to a picking station;

extracting, by a worker or robot, at least one part, which is predetermined according to a parts list, from the parts carrier;

depositing the extracted part on a further parts carrier; and

transporting, by a second one of the plurality of industrial trucks, the further parts carrier to a work station.

11. The method of claim 10, further comprising:

assembling the parts list is assembled according to a production volume of the work station.

12. The method of claim 10, further comprising:

storing, by the picking station in a storage device of the second one of the plurality of industrial trucks or the further parts carrier, the parts list.

13. The method of claim 12, further comprising:

transferring the parts list at the work station from the storage device to a robot of the work station.

14. The method of claim 10, wherein the parts list is determined by the control device according to a requirement of the work station and is transferred to the picking station.

15. The method of claim 10, wherein the first parts carrier is a rack.

16. The method of claim 10, wherein the further parts carrier is docked in a defined position at the work station by the second one of the plurality of industrial trucks.

17. The method of claim 10, further comprising:

transporting at least one component to be processed on a third parts carrier by a third one of the industrial trucks to the work station and docking the third parts carrier in a defined position at the work station.

18. The method of claim 17, wherein information about the at least one component to be processed is transferred from a storage device of the one of the third industrial trucks or of the third parts carrier to a robot of the work station.
