Automatic palletizers are automated machines or conveyor systems that
arrange a maximum load of packaged product units onto a pallet for
distribution. Pallet loads are frequently used for mass shipping and
distribution as a convenient means of consolidating many smaller units
into one larger, more easily handled unit.
Because individual packaged products
can be heavy, awkward and physically strenuous to handle manually, many
manufacturing and distribution plants use automated palletizing systems because they can withstand repetitive motion and heavy loads far better
than manual laborers. Automated palletizing machines may be designed to
handle a single type of product, such as bag palletizers, case
palletizers, drum palletizers and bottle palletizers, or they may handle
several different types of products. Additionally, automatic palletizing equipment accessories such as pallet dispensers and load transfer stations
are used to assist in managing both pallets and loads. Typical uses for
automated palletizers include shipping, packaging, distribution and
other materials handling applications in a wide range of industries such
as electronics, food processing, agricultural, warehousing, commercial
Automatic palletizers can be powered by
hydraulics, pneumatics or electro-mechanical equipment. There are two
main types of automated palletizers: robotic palletizers and
conveyorized automatic palletizers. Robotic palletizers are typically
stationed between a conveyor line of incoming product units and a pallet
dispenser. A hydraulic robotic arm lifts cases, bottles, bags or drums
using flat pincer arms or suction cup arms in organized rows onto a
pallet, stacking units with near-perfect precision. Robotic palletizers
may be altered to work with different types of product units and are
excellent for handling fragile or heavy product units, although they may
be slower, as they can only place one unit or row at a time.
Conveyorized palletizers have a feed area that receives the goods that
are to be palletized. The packaged units are received by roller
conveyors and are continuously transferred and sorted to the pallets by
automated conveyor rollers, allowing greater packaging speed than
robotic palletizers. There are two types of conveyorized palletizers: low-level palletizers
and high level palletizers. In low level palletizers, or floor-entry
palletizers, products are loaded from the ground level, while high level
palletizers are loaded from above or from the story above.
