Problem & answerF-07
Bottle Stop Sensor Not Working
Also covers: Feeder keeps sending bottles · bottles crushed
Likely causes
- Sensor lens dirty or dusty
- Sensor knocked out of alignment or bracket loose
- Sensing distance or sensitivity wrong for the bottle
- Cable loose or damaged
- Sensor failed
- Sensor delay setting incorrect
How to fix it
- 1Stop the feeder and conveyor immediately; remove crushed and damaged bottles.
- 2Clean the sensor lens (and reflector, if fitted) with a dry, lint-free cloth.
- 3Check the bracket is tight and the sensor aims at the bottle body at the correct height.
- 4Hold a bottle in front of the sensor: the indicator LED must change state. If not, adjust sensitivity or distance.
- 5Check the cable and connector.
- 6Check the sensor delay setting against the reference settings.
- 7Test: let bottles back up to the sensor. The feeder must stop when the queue reaches the sensor and restart when it clears.
- 8Replace the sensor if it still fails. Do not run the line with a faulty stop sensor.
Technical note
The stop (accumulation) sensor tells the bottle feeder when the conveyor is full. If it fails, the feeder keeps sending bottles; they pile up, jam and get crushed, and the whole line stops. Test it at every start-up.It is fixed when
Feeder stops every time bottles reach the sensor and restarts when they clear.
Stop it coming back
- Clean and function-test the stop sensor at every start-up.
- Lock the bracket so cleaning cannot move it.
