Problem & answerK-15
Cap Pusher Not Working
Also covers: Caps not pushed down onto the bottle
Likely causes
- Low air pressure
- Pusher cylinder or valve fault
- Pusher timing incorrect
- Pusher position not set for the bottle height
How to fix it
- 1Stop the capper.
- 2Check air pressure and the pusher cylinder movement.
- 3Check the pusher timing and its position over the bottle.
- 4Use the pusher function to push caps through and confirm each cap seats on the bottle neck.
- 5Contact Maintenance if the cylinder or valve does not respond.
Technical note
After a cap is placed, the pusher presses it down onto the bottle neck so it starts on the thread before the tightening wheels. The pusher can also be operated on its own to push all the caps through and feed them to the bottles, for example after clearing a jam.Photos
It is fixed when
Every cap is pushed squarely onto its bottle before tightening.
Stop it coming back
- Check pusher operation at start-up.
