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
