Function description

 

Packages arriving on a roller conveyor are scanned by a proximity switch (B0). If a package is present, it is lifted by cylinder A and then pushed onto another belt by cylinder B. Cylinder B should only move in again when cylinder A has reached its basic position again. A separation of the packages on the loading side took place beforehand. The cylinders are controlled by electromagnetically operated 5/2-way valves with spring return. The system can be reset centrally using the S1 button.
