Bottle unscrambler Troubleshooting

Symptoms: Downstream filler faults on flipped bottles, operators hand-correcting at the outfeed. Likely causes: Change parts wrong or worn; Hopper level too high or low; Air jets or sensors misadjusted. Fixes: Verify the correct sleeve and selector set for the bottle and replace worn orientation parts. Keep the working level in band; flooding the bowl overwhelms the selectors. Reset orientation air jets and confirm sensor timing for the format. Prevention: Format change checklist with first-off checks, change-part condition audits, hopper level control.

Symptoms: Repeat blockages at the same spot, elevator belt slipping, bottles wedged at transfer points. Likely causes: Static or dusty bottles; Damaged or lightweight bottle lots; Worn transfer guides. Fixes: Add ionisation and keep bulk bottle supplies covered; dusty rPET bridges in chutes. Audit incoming bottles; short-shot or ovalised bottles wedge where good ones flow. Polish or replace guides and verify gaps at every transfer for the format. Prevention: Incoming bottle audits, transfer gap checks at changeover, chute and guide wear PM.

Symptoms: Scuff rings and scratches visible after labelling, cosmetic rejects, customer complaints on premium SKUs. Likely causes: Overfilled bowl churning bottles; Rough or worn contact surfaces; Excessive backpressure at discharge. Fixes: Lower the working level so bottles single out quickly instead of grinding against each other. Replace worn liners and polish contact points; renew UHMW wear strips. Balance line speeds so bottles do not dwell and spin against guides. Prevention: Bowl level discipline, wear-strip PM, line balance review per format.
