7 Common Palletizing Line Faults & One-Click Troubleshooting Solutions for On-site Workers

During long-term 24-hour high-intensity operation, palletizing production lines will inevitably have minor common faults. Most shutdown problems do not require professional after-sales engineers. We summarize 7 on-site frequent faults and simple troubleshooting methods for front-line operators to solve problems quickly and shorten shutdown time.

Fault 1: Equipment cannot start after power on

Reason: Emergency stop button is not reset or safety fence door is open.

Solution: Reset all emergency stop buttons, close safety fence door tightly, and restart the control system.

Fault 2: Conveyor runs but products do not move forward

Reason: Conveyor belt slips or driving roller lacks tension.

Solution: Adjust belt tension knob, clean rubber dust on roller surface.

Fault 3: Robotic arm/column palletizer grabs goods unstably and drops materials

Reason: Air pressure insufficient or suction cup worn.

Solution: Adjust air compressor pressure, replace aging vacuum suction cup.

Fault 4: Stacked pallets are skewed and loose

Reason: Product positioning offset or palletizing program parameter drift.

Solution: Restart positioning corrector, restore factory palletizing program parameters.

Fault 5: Safety light curtain alarms frequently without reasons

Reason: Dust covers infrared sensor.

Solution: Wipe the light curtain lens with clean dry cloth.

Fault 6: Automatic pallet feeder cannot output empty pallets

Reason: Pallets are stuck mutually or separation cylinder pressure is insufficient.

Solution: Rearrange stacked empty pallets, adjust cylinder air pressure.

Fault 7: Whole line linkage stops suddenly

Reason: Front-end packaging machine sends fault signal.

Solution: Eliminate packaging machine fault first, then reset linkage system.

Tips for Daily Fault Avoidance

Do not shield safety protection devices privately; do not modify palletizing program parameters without authorization; clean material debris on the line in time.
