摘要

Sheet stack handling apparatus and method wherein sheets are formed into a stack and are secured in the stack by a clamp or the like and have a set of wheels applied to each stack and the stack is presented at a delivery station from which the stack is moved onto a pallet. The pallet is disposed at a declining angle so that the stack can roll down to a final position on the pallet and rows of stacks can roll onto the pallet. The pallet is supported by means which permit the pallet to shift laterally of the rows, so that additional rows of stacks can be placed on the pallet, and the shifting is also done under gravity by having a slight declining angle for the pallet shifting. Control mechanism is associated with the pallet and includes a detector for sensing the stacks on the pallet, and it includes a releasable stop for permitting the pallet to shift when the row of stacks is complete. The pallet has trackways for the rolling of the stacks therealong, and wells or openings are spaced along the trackways for receiving the wheels of the stack and thereby holding the stack in a fixed position when the pallet is lifted, such as by a lift truck. Also, the support for the pallet covers the pallet opening so that the wheels can roll through the openings when the stacks are moving on the pallet, such as for loading or unloading of the stacks. Thus the stacks are loaded onto a pallet and are then moved with the pallet to a distribution station where the stacks are unloaded, and the loading and unloading are both done under the influence of gravity by having the stacks roll on a decline and by having the pallet roll on a decline in the lateral shifting, as mentioned. and the stacks can then be moved or rolled to the feeding stations, and a switching mechanism is used for distributing the stacks from the distribution point into the selelcted feeding stations.
