Problem & answerK-12
Bottles Not Held Straight at the Capping Head
Also covers: Blue bottle-holding belts
Likely causes
- Blue bottle-holding (side grip) belts too loose: bottles lean or turn
- Belts too tight: bottles squeezed, stopped or deformed
- Left and right belt speeds not equal: bottles twist
- Belt speed not matched to the conveyor (reference bottle holder 38 Hz, conveyor 40 Hz)
- Worn or dirty belts
How to fix it
- 1Stop the capper and remove affected bottles.
- 2Adjust the belt gap so the bottle is held firmly and upright without being squeezed.
- 3Set both blue belts to the same speed and match them to the conveyor.
- 4Clean the belts; replace if worn or glazed.
- 5Run test bottles and watch them pass under the capping head straight and upright.
Technical note
The blue belts hold every bottle straight while the cap is placed and tightened. If they are wrong, caps go on crooked, do not go down or are not tightened. Check the grip and speed every time.Photos
It is fixed when
Bottles pass the capping head upright, straight and evenly spaced.
Stop it coming back
- Check belt grip and speed at start-up and at every bottle change.
