An operator manually inserts bearing hubs into the unfinished bearing roller at the pick-by-light manual workstation module. The workpieces are advanced to a defined position by the transfer line with the help of a baffle plate. A through-beam sensor detects the workpiece (bearing roller). The transfer line is stopped. The operator then removes the bearing roller from the conveyor belt and places it into the assembly tray.

The assembly tray has two assembly locations. The required assembly location in the assembly tray is indicated by means of a blue LED:

• Position 1 (-7P1):   assembly
• Position 2 (-8P1):   rework

The gravity-feed magazine for the bearing hubs allocated to the respective work step is indicated to the operator at the pick-by-light module by an LED. The operator grasps the bearing hubs and inserts them into the roller. The finished assembly is then returned to its previous conveyor belt position. The workpiece is detected by the through-beam sensor, the transfer line is started and the workpiece advances to the RFID reader.
