Position Monitoring of Robots in Block Storage Systems with Fork Sensors
In a cube storage system, vessels such as containers, boxes or crates are stacked, stored and removed by robots and transported through the storage system. To monitor the position of the robots and the number of crossings passed, two fork sensors are installed between the wheels. During travel, the light beam of the light barrier is interrupted because the bar of the rail is between the fork arms of the sensor. At intersections, the web of the rail is interrupted, the light beam hits the receiver and registers the crossing. Related applications can be found here.
