Side-Grip Belt Misaligned, Riding Up or Coming Off
Also covers: Belt re-fitting procedure
Likely causes
- Long use: belt stretched or worn
- Roller (pulley) not square or loose
- Belt tension uneven
- Product or dust on the rollers
How to fix it
- 1Stop the conveyor and isolate power at the PLC.
- 2Loosen the Allen (hex) screw and the 18 mm nut on the roller.
- 3Remove the conveyor roller.
- 4Clean the roller and belt.
- 5Refit the belt correctly around the rollers, seated in the roller groove.
- 6Refit the roller and set it square so the belt runs straight.
- 7Tighten the 18 mm nut and the Allen screw.
- 8Set belt tension so the belt is firm without over-stretching.
- 9Restore power, run the belt empty and watch it track straight; then run test bottles.
It is fixed when
Belt runs centred on the rollers without riding up; bottles transfer smoothly.
Stop it coming back
- Inspect belt tracking weekly; replace stretched or cracked belts.
