Accumulation Roller Conveyor
This type of conveyor serves as a buffer between products (normally pallets). The Accumulation Conveyor needs only one gear motor as the clocked transport of the pallets is regulated by pneumatics. When a pallet position is empty, the following pallet is lifted by a pneumatic valve and transported over this position. This procedure is automatically repeated every time a pallet leaves the conveyor.
At a take-over of the product, the pulley is free again and the products move up automatically.
Advantages
A sensor is not necessary because a simple pneumatic control stops the products and takes them off.
Furthermore, the entire conveyor requires only one drive.
