ABSTRACT:
Apparatus for receiving a stack of articles, such as rectangular cartons, disposed in a plurality of substantially horizontal layers and successively removing layers from the stack. The apparatus includes a bottom support onto which the stack may be conveyed, and an upright side support against which one side of the stack is supported. A top support is mounted on the side support in a position overlying the bottom support and is shiftable under power toward and away from the bottom support to clamp against the top of the stack. The bottom support, side support, and top support may be swung, concurrently, about a common, substantially horizontal axis 90.degree. in the direction of the side support to lay the stack over on its side with the same being supported by the bottom, side and top supports. The bottom support then is swingable under power from this laid-over position to return to its substantially horizontal position to return the bottommost layer in the stack to its initial, substantially horizontal position, while remainder layers in the stack remain supported in their laid-over position by the side and top supports. A conveyor is operable to carry the removed layer from the receiving station, after which the bottom support is swung under power to its upright position again, the top support is shifted under power toward the bottom support to slide the stack toward the bottom support, and the bottom support again is returned to its horizontal position to remove the next layer from the stack.
