In the case of concrete tiles (50 x 50 cm) for outdoor areas, a roller is used to apply paint as a nonslip coating. The tiles are conveyed “end to end” in the machine's inlet. If the production process is disrupted, then no tiles are conveyed and the machine stops. The machine's standstill has to be detected so that it is shut off.
Our switching optical motion sensor for non-contact feed control detects the continuous movement of the tiles. If the tiles are not moving, the machine is switched off.
