Figure 8-23 Roller conveyor with rotary table
A rotary table in a roller conveyor directs the material at the crossing of two conveyor lines. The
rotary table rotates through 90 ° from one end position to the other. 2 limit switches signal the
respective end position.
The signal to start the rotary table comes from the higher-level control system.
A xed setpoint in the converter supplies the speed setpoint.
