Bottle Cap Inspection
Challenge
To confirm that each bottle of water is capped completely before it is packaged
Solution
After bottles are filled and capped, they are conveyed under the WORLD-BEAM Q12 sensor at close range, before they are packed in cartons. The Q12 sensor, operating in fixed-field mode, detects missing or misaligned caps—regardless of color—and triggers the line to reject uncapped bottles.
Because the sensor uses fixed-field mode, it responds when a cap is not at the exact distance from the sensor that it should be.
