ABSTRACT:
Cases are accumulated in end-to-end relationship on a continuously driven infeed conveyor and stop means is provided adjacent the downstream end to selectively advance several cases in a group onto a pusher conveyor of the endless chain type. A lift table at the downstream end of the pusher conveyor raises these cases upwardly at a packing station where they are loaded with slugs of articles appropriately segregated for being dropped into the upwardly open packing cases in accordance with conventional practice. The packer accommodates the cases in each group in indexed relationship to one another and means is provided for so indexing the end-to-end cases. The endless pusher conveyor is spaced downwardly of the level of the cases on the infeed conveyor such that the second case in a group of two cases is received in a canted configuration with its leading edge supported on the top of the pusher associated with the first case. Fixed case camming means engages the outwardly projecting top flaps of the cases to urge or strip each of the cases rearwardly into its associated pusher before these cases are advanced to position for being lifted at the packing station. A pusher backup means is associated with the pusher conveyor chains to cause the pushers to be reversed in direction as the cases are being raised at the packing station in order to prevent interference when these cases are again returned to the pusher conveyor in order to be ejected from the packing station.
