Palletizer

摘要

An apparatus for palletizing or cubing layers of articles such as cartons includes a palletizer subassembly for stacking multiple layers of articles, a loading subassembly for moving a prepared layer of articles to the palletizer subassembly and an ejection subassembly for ejecting stacked layers of articles. The ejection subassembly includes an open frame selectively engaged by the loading subassembly for movement into the article palletizer subassembly. A pusher plate is slidably mounted for vertical movement on the open frame. The pusher plate is movable to a first position above a layer of articles on a preparation area so that a prepared layer of articles may be moved through the open frame and into the palletizer subassembly. The pusher plate is movable to a second position at which it will engage the stacked layer of articles when the open frame is shifted towards the palletizer subassembly by the loading subassembly.
