ABSTRACT:
Apparatus for de-palletizing and de-bagging stacks of articles such as can ends is disclosed. The de-palletizing apparatus discharges single bags of articles in seriatim order to a tilt tray comprising part of the de-bagging apparatus. The tilt tray delivers the bagged articles to a movable vertically oriented de-bagger pocket at a first or loading station. Opposed clamps engage the bottom of the bag and a pin below the bag is forced upwardly, thereby pushing the articles in the bag upwardly so as to form a void within the bag at the bag bottom. The movable pocket is then swung past a slitter station, where the bag bottom is severed and discarded. The now-severed bag and articles move to a second or de-bagging station, the bottom clamps are released, and a second set of clamps gently engages the bag. These clamps are moved upwardly to push and drag the bag upwardly from the stack of articles. As the bag moves upwardly, it is engaged in the nip of opposed rollers and drawn off and discarded. The now-debagged stack of articles is moved to a third or discharge station, for supply to a downstream processing machine.
