  • Patent number: 4494355
    Abstract: A case feeding apparatus moves open cases onto a lift table where each case is moved upwardly onto the funnel portion of a shifting grid structure so that a slug of articles can be deposited therein. Line pressure advances the cases toward a retractable stop and side belts move the cases individually into an intermittently operated pair of case conveyors capable of handling cases of different size. Arrival of a case at the lift table triggers both the raising and lowering of the lift table and an indexing device controls the case conveyor cycle. The cases have their side flaps folded down by side guides to maintain the case in laterally centered positioned on the lift table and each case conveyor has either pusher lugs or leading lugs to control case position longitudinally.
