Conveyor Stacker

This conveyor stacker accepts cut sheets or cards of various lengths and widths produced from continuous forms. The sheets are stacked in overlapped relationship.

As sheets 10 are separated from the continuous forms, they are deflected downward by denector springs 11 adjustably positioned on horizontol rod 12. Sheets 10 are deposited in overlapped relationship on intermittently advanced round belts 13 made of polyvinyl chloride material having a high frictional surface and moderate flexibility. Adjustable tracks 15 are provided beneath belts 13 to support sheets 10 and have slots 16 to accept removable separators 17. The latter are located in slots 16 in tracks 15 in proper relationship to the width of sheets 10. To accommodate various widths of sheets, tracks 15 supporting separators 17 are adjusted laterally a limited amount. A plurality of angle rods 18 at the ends of the stacker serve as a stop for stacked sheets 10.

A collating operation can be performed on the same unit by removing center separator 17 and adjusting the outer separators 17 to cause a partial merging of sheets 10 as they approach the terminal end of the stacker. Adjustment of springs 11 to insure the downward movement of two sheets 10 at different velocities is required.

Prior belt type forms stackers use motors or electromagnetic vibrators to laterally displace multiple streams of forms cut and slit from a single web. One or more properly located deflecting springs 11 over e...
