ABSTRACT:
An apparatus and method by which a single operator, at a single station, can pack pre-counted slugs of flat folded cartons, or trays, in one or more layers, in corrugated cases for discharge to a case taper several times faster than with manual packing by several operators. The "flats" are advanced in a longitudinal path on a secondary apron of a stacker, erect on one edge, pre-counted and divided into slugs, so that the single operator can slide each slug longitudinally past a one-way back stop onto a transfer table. The slug may be turned on its longitudinal axis by the operator for inspection and then compressed longitudinally by a ram against the back stop. The operator has already been presented with a single, flat, tubular case, from a stack of such cases, with the leading flaps folded back, and has manually erected the case and inserted it in a case gripper preferably poised above the table, thereby closing the minor bottom closure flaps. A start button brings the case gripper down to the level of the transfer table so that the operator can push the compressed slug laterally into the open case, resting on its side wall in the case gripper. The case is automatically lowered to receive the next slug and when full, is turned on a longitudinal axis through 90.degree. onto its bottom and discharged to a case taper while the case gripper returns to its original position above the level of the transfer table.
