Abstract

A workpiece machining method for a workpiece transfer system, wherein a workpiece and a workpiece carrier are introduced into a first station of the transfer system, and is subsequently machined in following stations wherein each station may comprise several manufacturing modules, and the workpiece is output in a last station.

Claims

1-12. -12. (canceled)

13. A workpiece machining method for a workpiece transfer system comprising:

positioning a workpiece on a workpiece carrier in a first orientation at a first work station;

passing the workpiece through one or more following stations in a first passage;

machining a first side of the workpiece as the workpiece is passed through the one or more following stations in the first passage;

automatically repositioning the workpiece on the workpiece carrier in a second orientation;

passing the workpiece through the one or more following stations in a subsequent passage; and

machining a second side of the workpiece as the workpiece is passed through the one or more following stations the subsequent time.

14. The workpiece machining method according to claim 13, wherein each following station comprises one or more manufacturing modules.

15. The workpiece machining method according to claim 13, further comprising:

outputting the workpiece at a last station after at least one subsequent passage.

16. The workpiece machining method according to claim 13, wherein the workpiece, after the first passage is returned to the first station via a return path.

17. The workpiece machining method according to claim 13, wherein the workpiece undergoes n passages, with n representing a number of the sides of the workpiece, and the workpiece is repositioned n−

1 times.

18. The workpiece machining method according to claim 13, wherein the workpiece carrier includes at least two accommodations for two workpieces, and the accommodations are charged accordingly.

19. The workpiece machining method according to claim 18, wherein a first workpiece for a first passage and a second workpiece for a subsequent passage are provided in respectively different accommodations on the workpiece carrier.

20. The workpiece machining method according to claim 18, wherein the workpiece carrier includes a defined accommodation for machining a top side of a workpiece and a defined accommodation for machining a bottom side of a workpiece.

21. The workpiece machining method according to claim 18, wherein after a first passage of a first workpiece, two workpieces are positioned on the workpiece carrier.

22. The workpiece machining method according to claim 13, wherein unmachined workpieces are made available in a stand-by area of the transfer system, and a respective workpiece made available is positioned on the workpiece carrier and introduced into the transfer system after the output of a finished workpiece.

23. A transfer system for implementing the method according to claim 13, wherein a station is equipped with an automated handling device configured to reposition the workpiece to the second orientation after the first passage.

24. The transfer system according to claim 23, wherein the automated handling device is a robot.

25. A transfer system for implementing the method according to claim 13, wherein the workpiece carrier includes at least two accommodations for two different workpieces.

26. A transfer system according to claim 25, wherein the accommodations are designed to automatically adjust themselves so that each of the accommodations is adapted to accommodate a respective workpiece.

27. A transfer system for implementing the method according to claim 13, wherein the workpiece carrier includes clamping means for the workpiece, and the clamping means includes at least one spring.
