<p>An apparatus (30) for unstacking cross-nested articles includes an elevator (60) which raises the stack (31) as articles are removed two-at-a-time from the top thereof by a continuous-chain transfer conveyor (130). The transfer conveyor carries the removed articles to a discharge station where they are dropped onto two vertically spaced-apart discharge conveyors (181,190). In one embodiment, the upper discharge conveyor (181) comprises laterally spaced-apart tracks (185) arranged so that the bottom article drops therethrough to the lower discharge conveyor (190), while the top article is caught on the upper discharge conveyor. A finger (207) on one of the conveyors turns selected articles 90 DEG so that all articles are aligned in the same direction as they exit the lower conveyor. In another embodiment both discharge conveyors (181,220) comprise laterally spaced-apart tracks (185,225), and a turntable (230) is vertically movable between the tracks to lower the articles onto the discharge conveyors, the turntable rotating 90 DEG between the discharge conveyors to reorient the lower article.</p> |
