8 Function

The separating station consists of 2 Conveyor modules. The station detects the height of incoming
workpieces and allocates them.
A diffuse sensor at the start of the conveyor detects the inserted workpiece. A distance sensor above the
stopper detects the inserted workpiece and controls the further material flow. Depending on the rating a
separator is switched. If the pick-up point and the conveyor section is not occupied the stopper is retracted
and a workpiece is transported to one of both conveyor belts.
Through-beam sensors and diffuse sensors control the further material flow on the conveyor belts. The
Separating station can be supplemented with MPS
Output signal of the distance sensor
The distance sensor has both an analogue output and a switching output. The switching output can
be adapted to the measurement requirement by means of a simple teach-in stage.

9 Sequence description

Start prerequisites
 No workpiece at start of conveyor
Initial position
 Stopper advanced
 Separator retracted
 Conveyor motors off
Sequence
1. The conveyor belt motor 1 switches on if a workpiece is detected. The workpiece is transported to the
stopper.
2. The conveyor belt motor 1 is switched off, if the workpiece is detected by the diffuse sensor in front the
stopper.
3. The differentiation of the workpiece takes place by the distance sensor above the stopper.
