Abstract

In a stacker 21, document cards 11 pass over roll 27 one-by-one as transported by belt 10. They pass into contact with a pinch-point formed by roller 14 and pressure shoe 32 and then into contact with card guide 37 which directs cards 11 downwardly edgewise into pocket 25. Supporting plate 41 for cards 11 is disposed in pocket 25 and is yieldably held from downward movement so as to support a stack of cards therein.

Card Stacker

In a stacker 21, document cards 11 pass over roll 27 one-by-one as transported by belt 10. They pass into contact with a pinch-point formed by roller 14 and pressure shoe 32 and then into contact with card guide 37 which directs cards 11 downwardly edgewise into pocket 25. Supporting plate 41 for cards 11 is disposed in pocket 25 and is yieldably held from downward movement so as to support a stack of cards therein.

Each of the cards 11, as it travels into pocket 25 on top of previous cards, drivingly rotates roller 35. This roller is disposed at the upper end of pocket 25 and is rotatably supported on a cantilever spring 39 fixed by means of a rivet 40 with respect to mounting 29. Cards 11 deflect cantilever spring 39 while making contact with roller 38 and cause roller 38 to rotate so that the roller drives the cards forwardly to card stop 36 and snaps cards 11 off of pressure shoe 32. Roller 38, due to its rotation, prevents substantial rebound of cards 11.

Spring 39 yields for the thickness of the card and also forces the stack of cards downwardly by moving plate 41 in pocket 25 so as to maintain the top of the stack adjacent the lower horizontal surface of mounting 29.
