Document Stacker

In a document sorting operation, stacking apparatus is employed which maintains the last selected document segregated from those already stacked to permit easy removal for inspection.

The stacking pocket is one of a plurality. Documents are selected into the pocket from a main transport path. A selected document 1 enters along guides 2 and slides on vane 3a of vane wheel 4 until arrested by stop 5. The document is maintained on edge between shield 7 and previously stacked documents 8 or backer plate 9 pivotally mounted on base 10 which is rotatably mounted on fixed stud 11.

Upon selecting the next document for this stacking pocket, an electrical signal is generated which energizes solenoid 12 to pull its plunger 13, rotating bellcrank 14, and pulling link 15 downwardly to increment ratchet 16 via pawl 17. Gear 18, fixed to ratchet 16, engages gear 19, fixed on shaft 20 to which wheel 4 is attached. The ratio between gears 18 and 19 is such that the incremental movement of ratchet 16 rotates the shaft 90 degrees clockwise in supports 21 so that vane 3b assumes the position of vane 3a.

When vane 3a moves downwardly, document 1 follows and drops on base
10. Flange 22a on vane 3a swings the previously stacked documents and base 10 sufficiently to allow document 1 to be seated without interference. The next document enters the pocket on vane 3b and remains until another document is selected for that pocket. Stacker base 10 may be urged toward wheel 4...
