It is fully automated device to built unit loads. It is used when high throughput of identical loads is required e.g. the manufacture pallet loading problem. It typically has a greater capacity i.e. 30-180 items per minute than pick and place because the entire layer is placed on the load at one time. It is not as flexible as pick and place palletizer. Preformed layer of items are indexed onto the stripper plate or apron; when properly positioned over the pallet, the apron is pulled out from underneath layer to deposit the layer onto the pallet. In-line - pattern formation or top picture where flexible patterns are not possible. It is ideal for high speed operation up to 180 items per minute. It takes up more room as there is a larger machine than right angle. Right angle - pattern formation or bottom picture have very flexible patterns which are possible. It can handle a wide variety of case sizes and types. It has a limited capacity up to 80 items per minute which is a compact design.
