Function
In the Processing station, workpieces are tested and processed on a rotary indexing table. This station only uses electrical drives. The rotary indexing table is driven by a DC motor. The table is positioned by a relay circuit, with the position of the table being detected by an inductive sensor. On the rotary indexing table, the workpieces are tested and drilled in two parallel processes. A solenoid probe with an inductive sensor checks that the workpieces are inserted in the correct position. During drilling, the workpiece is clamped by a solenoid actuator. Finished workpieces are passed on via the electrical sorting gate.

Attention! - Drilling operation

Drill feed is undertaken by an electrical linear axis with a DC motor, which is controlled via a reversing starter. The end positions are sensed by means of micro switches. The drill is fully functional, but for safety reasons the drilling processes are only simulated.

Electrical only: Many different drives

The station requires the programming of two processes executed in parallel: drilling and drill-hole testing. This station also offers a range of different drives:

• DC drill
• DC motor on rotary indexing table
• Electrical linear drive for drill feed
• Electrical sorting gate
• Solenoid actuator in the clamping module and the Testing module
