ABSTRACT:
An article handling and pushing device is located on one side of a set of stacked shelves, is movable vertically, and includes a transfer shelf which can be brought to oppose any selected one of the stacked shelves by such vertical motion and also a push arm for moving articles from the transfer shelf away from the handling and pushing device onto the currently selected opposed one of the stacked shelves. An article pushing out device is located on the other side of the shelves, is also movable vertically, also can be brought to oppose any selected one of the stacked shelves by such vertical motion, and includes an air cylinder for pushing articles off from the currently selected one of the stacked shelves away from itself. A raising device moves both the article handling and pushing device and the pushing out device vertically, and keeps both of them at substantially the same height at all times. Optionally, the raising device may include an elevator device which is movable in a certain direction, a first and a second cable, and first and second pulley systems over which the first and the second cable respectively pass, the one ends of the first and second cables being attached to the elevator device so as to be pulled by it during its motion, and the other ends of the first and second cables being respectively attached to the handling device and the pushing out device so as to support them vertically.
