Abstract

Article packing or unpacking apparatus, including two correlated driven conveyors, the first for articles and the second for moving cases through a fixed course having a horizontal section and with both conveyors having fixed orbits, the article conveyor being in a vertical plane above the horizontal section of the second conveyor; and article grippers are positioned by carrier bars engaged with the article conveyor, which grippers depend from the carrier bars in a lower reach of such article conveyor. A pair of control arms are individually secured to each carrier bar at different ends thereof to engage guides as the article conveyor is moved downwardly towards an inflection area so that the article grippers are presented on vertical axes as they are moved into, along with cases moving through the horizontal section of the case conveyor fixed course. The articles are deposited in a case, and the guides and control arms move the article grippers up away from the case with continued downstream movement of the conveyors.
