ABSTRACT:
Method and apparatus for de-palletizing and de-bagging stacks of articles such as can ends is disclosed. The de-palletizing apparatus removes a single layer of bags and discharges single bags of articles in seriatim order to a tilt tray comprising part of the de-bagging apparatus. The tilt tray moves the bag of articles to a vertical position, and inserts the bagged articles in a movable pocket at a 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 at the bag bottom. The movable pocket is then moved past a slitter station, where the bag bottom is severed and discarded, to a de-bagging station. The opposed clamps are released, and a second set of movable clamps engage the bag to force the bag upwardly. As the bag moves upwardly, a pair of opposed rollers draw the bag off the stacked articles. The now-debagged stack of articles is moved to a discharge station.
