Looping Document Stacker

Record documents of varying degrees of rigidity are stacked reliably, in alignment, at high speed by depositing them in a stacker with a rolling motion.

In A, document 1, propelled along passageway 2 and aligned against flange 3, has its leading edge guided onto rotating drum 4 by helical guide bar 5. Drum 4 rotates about axis 6 with idler rollers 7, 8 and 9 resiliently urged against the drum periphery. Drum 4 is angularly disposed relative to passageway 2 so that the entrance of document 1 under roller 7 causes all points of edge 10 to move in parallel away from flange 3.

In B, continued movement of drum 4 causes document 1 to free itself of rollers 7 and 9 while the leading edge of document 1 enters between clip 11 and depressible stacker plate 12 against wall 13. The rotation of drum 4 and roller 10 then causes document 1 to loop outwardly and fall on stacker plate 12 in an inverted position. This stacking arrangement permits documents to enter the stacker at high speeds with minimal damage at the leading edge.
