A compact teaching and practice unit for the control of a materials handling process using a PLC.
Two processes can be simulated: a punching process, or workpiece control in the form of a sort operation. All components are in a clearly laid out design.
Black and white cylindrical workpieces are fed from a container onto a conveyor belt.
On the belt is a reflex photoelectric proximity switch which differentiates between light and dark and feeds the white items to the pre-selected process (punching or sorting).
The black workpieces are always carried to the end of the belt, where they drop into a collector.
