A package is transported - from the lower roller conveyor (left) to the end of the upper roller conveyor (right). A lifting and ejection device is used to transport the goods to the other level. These devices each consist of a pneumatic cylinder with limit switches. A parts check is located directly in the lifting station. The package is released via the visualization.
