Palletizers are machines that place goods on pallets in an orderly fashion. They come in many different different configurations to handle a multitude of different packaging, incoming material lines, and automation requirements. Specific palletizers are available to handle bags, pails, drums, crates, cases, and kegs, etc. Many of these devices are configured to handle more than just one package style.
Palletizers are available in a number of different function configurations, differentiated by the manner in which they receive goods to place on a pallet. The three most common configurations are low level, high level and robotic. Low level palletizers are feed at ground level, while high level devices receive product through a hopper from above. In both cases, product may be received in a rolling or flowing fashion and continuously transferred to pallets. These types of palletizers are best used in applications where packing and shipping speed is important. However, they may be inadequate in situations where the product being shipped is fragile. In such cases, robotic palletizer should be used. These devices pick up, orient, and place materials onto a pallet one at a time. While slower, they tend to apply less stress to the materials while transferring them to a pallet.
Automatic and Semi-Automatic Devices
Commercial palletizers are available as fully automatic and semi-automatic devices. Fully automatic machines perform their function without operator intervention. Operator involvement is usually limited to replenishment of packaging components, e.g., loading empty bags or cartons on the filling systems magazine, loading bulk material supply hoppers, placing empty pallets on the palletizers magazine, removing completed cartons or pallets from the system, etc. Semi-automatic palletizers allow a single operator to stack layer after layer of heavy loads onto pallets with no lifting.
