Cartons Are Crushed or Bottles Are Damaged in Case Packing

Check whether the case lacks strength or the machine applies excess force. Measure carton condition, pack geometry, compression, pusher load, guide clearance and downstream backpressure.

Use lockout/tagout before clearing a jam or entering the guarded packaging or palletizing cell. Allow heaters and sealing bars to cool, and secure suspended or robot-handled loads.

Locate the fault

• Case corners buckle after closing
• Bottle caps or labels scuff inside the carton
• Pusher or servo load alarms occur
• Damage appears only in one pack pattern

Inspection sequence

1. Inspect damage location and determine the first station where it appears
2. Verify carton material, moisture condition and dimensions
3. Measure the assembled product group and internal case clearance
4. Review pusher torque or force and actual end position
5. Inspect mechanical stops, compression belts and guides
6. Check downstream accumulation and case release timing

Corrective work

• Use carton board qualified for storage and load conditions
• Correct pack pattern, dividers or case dimensions
• Restore pusher and compression settings and repair binding
• Reduce harmful downstream backpressure and improve release control

Operating records and follow-up

• Incoming-check board and score quality
• Control carton storage
• Trend servo load
• Qualify every pack pattern
• Inspect downstream handling as part of packer setup
