IDEA NOTE Workpiece presence Yes/No detection method
Urethane Bumpers are mounted on the tip of the detection units to avoid scratching the containers.
IDEA NOTE Two detection units are used.
When the container is somewhat large as in the supplemental example and position needs to be detected with reliability, 2 detection units placed diagonally increases the reliability. Foreign objects under the tray can be detected as well with this set-up.
