What Is Auto-Rejection System?
Direct Answer
An auto-rejection system is a production mechanism that automatically removes defective products from the line using air blasts or diverters.
Key Takeaways
- An auto-rejection system is a production mechanism that automatically removes defective products from the line using air blasts or diverters.
- How it works: When a defect sensor (vision, weight or metal detection) flags a product, the rejection unit fires an air blast or moves a diverter to push it off the line before packing.
- Rejecting diapers with shifted cores detected by vision
- Rejected products are reworked automatically — most are discarded or sent for offline inspection, not auto-reworked
How Auto-Rejection System Works
When a defect sensor (vision, weight or metal detection) flags a product, the rejection unit fires an air blast or moves a diverter to push it off the line before packing. This keeps defective units out of consumer packs without slowing production.
Examples and Applications
- Rejecting diapers with shifted cores detected by vision
- Removing packs with metal-contamination flags

How does an auto-rejection system work?
Sensors flag defects; a pneumatic or mechanical diverter removes the unit from the line in real time, so only confirmed-good products reach packing.
