ABSTRACT:
Apparatus for transporting stacks of paper sheets from a gathering station which receives successive rows of aligned stacks to two packing machines has a discrete staggering conveyor for each stack of a row. These conveyors serve to convert each row into two groups of staggered stacks and cooperate with auxiliary conveyors which deliver such stacks to successive pallets of two separate sets of pallets which advance the stacks toward the respective packing machines. The pallets of each set travel along a separate main track. The main tracks are parallel to each other and flank two crossing connecting tracks. When a packing machine is idle, the rate of delivery of rows of stacks to the gathering station is reduced in half and the pallets which normally advance along the respective main track are diverted onto one of the connecting tracks which guides them sufficiently close to the pallets of the other set to shuffle the two files of stacks so that the resulting single file of stacks can be transported to the active packing machine. To this end, the pallets of one set are staggered with respect to the pallets of the other set, and the pallets of each set are separated from each other by gaps each of which is wide enough to receive a pallet. The pallets are slidable along motion transmitting rods which are mounted on two parallel chains and extend transversely of the main tracks.
