PALLETIZING SYSTEM AND METHOD

摘要

A first layer of items is assembled on a movable conveyor belt on a support platform, and the conveyor belt advances to position the first layer of items above and in registration with a pallet while a second layer of items is assembled behind the first layer. The conveyor belt then stops, and part of the support platform and an associated portion of the conveyor belt retract from beneath the first layer of items, depositing the first layer of items on the pallet, after which the pallet is indexed downward. The retractable portion of the support platform and the associated portion of the conveyor belt then extend to the position above and in registration with the pallet, and the conveyor belt advances during this extension to position the second layer of items above and in registration with the pallet. Apparatus for placing slip sheets onto pallets is also described.
