Abstract

The stacking device comprises gate 1, hinged on upper pivot 2, and gate 3, hinged on lower pivot 4. Gates 1 and 3 are normally vertically disposed and slightly spaced to provide a guideway above ledge 5, projecting laterally from arm 3.

Stacking Device

The stacking device comprises gate 1, hinged on upper pivot 2, and gate 3, hinged on lower pivot 4.

Gates 1 and 3 are normally vertically disposed and slightly spaced to provide a guideway above ledge 5, projecting laterally from arm 3.

Driven roll 6 and idler roll 7 cooperate to advance sheet 8 successively through this guideway in a direction toward the reader, (A), to a predetermined point. At this point, suitable sensing devices (not shown) detect the presence of sheet 8 and trigger a mechanism (not shown) to swing gate 1 and roll 7 clockwise and swing gate 3 counterclockwise. This action swings sheet 8 flatwise through a 90 degrees arc until it is deposited on top of stack 9 in pocket
10. The bottom of 10 is preferably defined by spring-biased arm 11. As the stack thickness increases, arm 11 lowers and tends to maintain the top of the stack at a substantially uniform height.

Knock-off member 12 has fingers 13 (B and C) which move through perforations in gate 3 as the latter starts to move up away from stack 9 to assure that the sheet is not held by static electricity against gate 3. The sheets are stacked neatly without requiring joggling prior to further processing.
