Pattern faults / frequent jams

Hits OEE: Performance

Symptoms: Misformed layers, toppled product, stops at the layer/row former.

Infeed orientation/spacing wrong

Check row-former and turning devices; correct spacing.

Worn/misadjusted guides or grippers

Inspect and reset change parts for the pattern/SKU.

Product or pallet variation

Tighten incoming pallet/product spec; re-teach the pattern.

Prevention: Pattern setup sheets, change-part inspection, pallet/product QA.

Dropped or mis-placed product

Hits OEE: Quality

Symptoms: Cases dropped or placed off-pattern, unstable stacks.

Gripper or vacuum fault

Check grip force/vacuum and cups; replace worn parts.

Taught position drift

Re-teach place positions; check for mechanical knocks.

Product or case variation

Tighten incoming case spec; adjust handling.

Prevention: Gripper maintenance, position checks, case QA.

Pallet or infeed feed fault

Hits OEE: Availability

Symptoms: No pallet present, pallet jams, or infeed starves and backs up.

Pallet dispenser jam

Clear the magazine; remove damaged pallets.

Infeed sensor or conveyor fault

Check infeed sensors and the conveyor drive.

Poor pallet quality

Stop the same fault coming back

Recurring palletizer stops usually trace to a cause you cannot see by hand. The partner we recommend is Fabrico: EU-built, so your production data stays in EU jurisdiction, with computer-vision true-cause of micro-stops, a closed loop from PLC-read OEE to an auto-routed work order, and ISO 27001 / 20000-1 / 9001 (supports audit-readiness).
