Feeding station incl. ram protection
Corner transfer unit
Loading station with lifting table
Unloading station incl. ram protection and end stop
The infeed station incl. impact protection is located outside the safety fence. The forklift driver places empty pallets on the conveyor as a stack of up to 10 pallets. If the empty pallet stack is empty on the subsequent section, within the safety area, this empty stack cycles through the light barrier into the safety area and is taken over and lifted by the pallet magazine. The roller conveyor with superimposed pallet magazine sets down the bottom pallet on request and conveys it to the downstream corner transfer unit. The corner transfer unit with end stop is a combination of roller conveyor and lifting/lowering chain conveyor. If an empty pallet now enters, it travels through to the end plate and aligns itself in this way. The chain conveyor, which is installed between the rollers at right angles to the roller conveyor, then lifts the empty pallet off the roller. On request from the palletizing station, the empty pallet moves from the lifted chain conveyor of the corner transfer unit onto the chain conveyor on the scissors lift table.
The palletizing station consists of an electro-hydraulically operated scissor lift table with an attached chain conveyor. The lifting positions are always the end positions and the robot then loads the pallet. When the pallet is full, the lifting table is lowered again and the pallet moves to the next position where it waits for the signal.
On this track there is always only one full pallet waiting for a free place on the unloading station. The unloading station is also a chain conveyor with space for 3 Euro pallets. For safety reasons, there is a fixed stop at the end of the conveyor. The 3 possible full pallet places are pre-clocked by means of light barriers. The forklift driver is instructed so that he always clears the pallets from the left side as seen from his position. A „RED-GREEN“ light signal shows him whether clearing is allowed or whether a pallet transport action is pending.
