Document Turnover Mechanism Utilizing Reversing Slip Clutch Drive

Shown is a document turnover device to provide reorientation of a document prior to its being fed into a collator, so that the proper orientation of the document is present when collating duplexed copies from an electrophotographic copying machine or other printing apparatus.

A feed mechanism feeds sheet 10 into pinch roll 12 and belt 14.

The sheet is deflected downward by deflector 16 to cause it to enter between belts 14 and 18. The sheet is continued to be fed into the region between belts 14 and 18, until the leading or plus edge of document 10 engages switch finger 20 and closes switch 22. The closing of switch 22 disengages clutch control 24 to deactivate clutch 26, thereby allowing slip clutch 19 to become effective causing a reversal of belts 14 and 18. This action feeds the document out of the region between belts 14 and 18 to where the document is again diverted by deflector 16 into the nip formed by rolls 28 and 30, to cause the paper 10 to reenter the paper transport mechanism. Slip clutch 19 may be overdriven in the counterclockwise direction and is capable of driving in the clockwise direction, when not opposed by countering forces.

This device accomplishes a sheet-by-sheet reorientation of the output sheets from a duplex operation, so that sheets are properly orientated for collating.
