The task of the drilling module is

• to move workpieces to the correct position and
• to machine the workpiece by adding a drill hole (simulated).

The module drills workpieces (symbolically). The workpieces are detected on the conveyor belt by an optical diffuse sensor. The drilling machine is moved down by means of a pneumatic slide.

Advancing and retracting speed of the linear slide can be infinitely adjusted with the help of one-way flow control valves.

If a workpiece is positioned underneath the drilling machine by the transfer system via the baffle plate, and if the fiber-optic cable at the baffle plate detects the workpiece, the conveyor belt is stopped and an automatic sequence is started. The linear slide moves down and symbolically drills a hole. The linear cylinder then travels back up to its initial position. When the linear slide is at the top, the conveyor belt is re-started and the workpiece leaves the module.
