  • Patent number: 4764074
    Abstract: An apparatus for placing a load of stacked articles on a pallet. This apparatus comprises a conveyor having a series of spaced rollers and a bridge structure spanning the conveyor. Two load lifting structures hang vertically from the bridge structure, one on each side of the roller conveyor, and are displaceable toward and away from one another over the conveyor. Each lifting structure has a lifting frame formed of a vertical ram wall, a tine carrier at the lower end of the ram wall, and an operating base supporting the tine carrier during its displacement. The pallets are fed from a pallet unstacker delivering one pallet at a time on a pallet conveyor extending at a right angle from the roller conveyor. The pallets are fed onto the roller conveyor when the ram walls and tines of the load lifting frames are lifted above the roller conveyor a distance sufficient to allow insertion of the pallet. The load between the lifting frames is then lowered onto the pallet.
