Reject and line integration

Automatic reject integration with positive control

An inspection is only effective when a failed pack is removed reliably and its removal is confirmed. We integrate the camera decision, encoder tracking, reject device, guarding, bin controls and line logic as one engineered system.

Inspection overview

From pass/fail decision to controlled containment

The reject method must suit product weight, shape, speed, pitch and fragility. Air blast may suit light packs, while pushers, drop flaps, retracting belts or lane diverters may provide better control for heavier or unstable products.

Positive reject confirmation can verify that the device operated or that the failed pack entered the reject path. Bin-full detection, locked access, consecutive-failure alarms and fail-safe line stops can be added according to the process risk assessment.

Checks that can be combined

The final inspection set is selected from the visible features, risk, product presentation and achievable image resolution.

  • Encoder-based product tracking
  • Air blast, pusher, diverter or drop-flap control
  • Reject confirmation sensing
  • Lockable reject-bin integration
  • Bin-full and bin-present monitoring
  • Consecutive-failure and rate alarms
  • Camera, PLC and upstream machine handshakes
  • Fail-safe stop and fault recovery logic

Application details we review

Early clarity on these points helps avoid false rejects, blind spots and mechanical changes late in the project.

  • Product mass, speed and stability
  • Distance from camera to reject point
  • Conveyor gaps and product accumulation
  • Safe access and guarding
  • Required confirmation and containment level
  • Existing PLC, electrical and pneumatic standards

Engineer the reject around the real line dynamics

Reject trials confirm timing, containment and recovery across normal speed, spacing and changeover conditions—not just a single ideal pack.

Feasibility work establishes the camera view, lens, light, exposure and image-processing approach. We then define the enclosure, conveyor changes, controls, operator interface and rejection needed for production.

How we deliver

From feasibility to supported production

Inspection performance depends on the complete cell, so optics, mechanics, controls and rejection are developed as one project.

Define

Products, defects, speeds, environment and acceptance criteria.

Prove

Sample imaging, lighting trials and achievable defect limits.

Integrate

Mechanical design, guarding, PLC, recipes and reject tracking.

Support

Commissioning, operator training and production handover.

Automatic reject integration questions

Technical questions, answered clearly

Which reject method is best?

It depends on the product and line. Pack weight, centre of gravity, fragility, speed, pitch, conveyor design and required containment determine whether air blast, pusher, drop flap, retracting belt or diverter is appropriate.

How does the system reject the correct product?

An encoder or controlled timing model tracks each inspected item from the camera to the reject point. Stable product detection and known conveyor behaviour are essential.

Can the system prove the failed product was removed?

A reject-confirm sensor can detect product entering the reject path or verify actuator operation. The required level of confirmation is agreed from the process risk.

Can the reject bin be locked?

Yes. Secure bins can include lid or door interlocks, bin-present detection, bin-full sensing and controlled access where the application requires it.

Can the system stop after repeated failures?

Yes. Configurable consecutive-failure, failure-rate and hardware-fault logic can alarm, reject or initiate a controlled stop through the line PLC.
