ABSTRACT:
An apparatus and method for the stacking and restacking of printed paper, cardboard and the like are disclosed. Included in the apparatus is a turnover mechanism which receives stacks of sheets on a pallet or skid and, after clamping, turns this skid about ninety degrees so that the sheets are on edge and in a substantially vertical condition. There is provided a sheet edge support and in combination with this edge support are vibrating shoes which have air blast openings formed in their sheet engaging surfaces. These shoes are preferably flat and are vibrated so as to jog and move the sheets toward a stop which is preferably adjustable. The shoes may have an upwardly directed surface, if desired, and with this upward guidance the sheets are locally lifted when these vibrating shoes are moved underneath. The turnover mechanism has clamp means by which the stack is gripped and lifted. When the stack has turned about ninety degrees the turnover mechanism is stopped for the aligning operation. The shoes are carried by a side frame portion of the turnover mechanism. This side frame becomes the support and includes rib members between which the vibrating shoes are moved in a common plane. When the shoes are flat the upper shoe surface and the edge support for the sheets are in, and maintained in, a common plane. When the shoe surface is at least locally directed upwardly a small portion extends above the support plane to displace the sheets upwardly as the shoe passes underneath.
