Diverters & Rejects

Devices integrated with conveyors to remove, divert and stage for collection packages or containers considered rejects, such as unlabeled or otherwise defective items, or to otherwise separate products from a packaging line, such as in quality checks.

Category Explained

Diverters & Rejects are devices designed to work alongside conveyor systems, facilitating the removal, diversion, and staging of packages or containers identified as rejects due to reasons like missing labels or defects. These units are essential for ensuring product quality by segregating items that fail to meet specified standards. Additionally, they play a crucial role in sorting products during packaging processes, enabling efficient quality control and management of goods before final packaging. Their functionality is critical in maintaining the integrity of production lines by swiftly isolating items that require further inspection or removal, thereby optimizing the flow of products and minimizing downtime.

Diverters and reject systems typically use mechanical arms, air jets, pushers, or gates to redirect items without stopping the conveyor line. They can be triggered by sensors, vision systems, or weight checkers and are strategically placed at inspection points to immediately remove non-conforming products. Some systems also route accepted products into multiple lanes for sorting or batching.

Typical products and applications include:

  • Unlabeled or misprinted containers: Automatically removed from the line before reaching packing stations
  • Overfilled or underfilled bottles: Diverted after weight or fill level inspection
  • Damaged packaging (e.g., dented cans or cracked trays): Isolated for review or disposal
  • Pharmaceutical blister packs missing tablets: Rejected following vision system inspection
  • Snack pouches with sealing issues: Diverted before case packing for quality assurance

Additional Considerations:

  • Supports quality assurance by automatically removing non-compliant products
  • Can be integrated with checkweighers, metal detectors, or vision inspection systems
  • Reduces manual inspection needs and improves line speed
  • May include collection bins, retractable conveyors, or product counting features
  • Enhances traceability and documentation when paired with inspection logging software
