Abstract
Apparatus is provided for arranging a row of bundles, preferably tied or untied bundles of folded or unfolded corrugated boxes or blanks, into stacks which include a plurality of layers of one or more bundles. The apparatus includes a feeding conveyor for feeding a row of bundles to a loading conveyor. A worker is stationed at the loading conveyor and functions to arrange the bundles into a layer on the loading conveyor. The loading conveyor then operates to transfer the layer of bundles to a transfer station on a vertical conveyor. Alternatively, the worker can arrange the bundles directly at the transfer station. The vertical conveyor includes a plurality of carrier plates which each operate to lift a layer of bundles from the transfer station and transfer it to a delivery station on the other side of the vertical conveyor. Each carrier plate includes a plurality of pushers so that the next carrier plate operates to push the layer of bundles from the delivery station onto a stripping conveyor which pushes the layer against a striker plate located above a downstacker. A stripping conveyor surrounds the downstacker and includes at least one opening therein through which the layer o…
