Pallet stacker
Automation of the container handling in incoming goods.

KLT bundles (sub-pallet, KLT container, lid) are stacked on top of one another in towers for the transportation on trucks. After unloading (at the destination), the individual towers are placed on chain conveyors with forklifts. When entering our stacker, the pallet size is recognized (type 111444 or type 114003) and the pallet is automatically getting centered. In order to separate the containers, it is necessary to identify and lift the second steel pallet, seen from below. The lowermost KLT (small load carrier) bundle that has become free and is still on the chain conveyor is now moved out of the stacker. As soon as there is no longer any interfering contour for the KLT bundle being held, the lifting arms move downwards and place the pallet on the chain conveyor. The next steel pallet is now located. As soon as it has been recognized again, the procedure is starting over.

This process is repeated until no more steel pallets are recognized and the sensors indicate the end of the tower.

 

Normally, the bundles made of large steel pallets (type 114003) are stacked to form a tower of three (approx. 3000mm high). Bundles made from small steel pallets (type 111444) are stacked up to a maximum of 5 pieces (approx. 2400mm high). The total weight of the tower may be 3000kg. The maximum weight of a container must not exceed 1000kg.
