Cap height (cap fit) sensor

After the capper, a side-mounted sensor checks every cap is 100% fitted to the bottle. Its beam is set just above the level of a correctly seated cap. A cap that is high, tilted or not fully screwed down breaks the beam and the bottle is rejected (K-19).

1. 1Clean the sensor lens.
2. 2Set the sensor height so the beam passes just above a correctly seated cap for this bottle; lock the bracket.
3. 3Pass a bottle with a deliberately loose or crooked cap: it must be rejected.
4. 4Pass a correctly capped bottle: it must pass.
5. 5If either test fails, stop and adjust before production.
6. 6Record the test at start-up, after bottle changes or adjustments and at batch end.
