ABSTRACT:
A rotating carousel and bag handling apparatus comprising a rotating carriage plate driven by a motor and carrying a plurality of trays filled with bags. The trays are each maintained in a stable, level position by a timing collar, belt, and pulley assembly connected to each tray. As successive bag trays are rotated to a pickup position adjacent a bag handling mechanism, a brake assembly momentarily stops the motion of the bag carousel sufficient for a bag handling arm to pivot down over one of the bag trays, and for a plurality of bag grippers to grip and hold the top bag in that tray. The bag handling arm then pivots back upwardly and away from the tray carrying the bag onto a bag support assembly displaced over the conveyor belt and mounted on a pair of rocker arms, with the longitudinal edge of the bag being positioned adjacent to a side retaining wall on the conveyor belt. As the bag is released, the rocker arms and bag support assembly pivot away from the side retaining wall of the conveyor belt, allowing the bag to slide off the bag support assembly and lay flat on the conveyor belt in a spaced-apart or overlapping relationship to a previously transferred bag.
