Automatic reject systems.
Track and verify removal.
An automatic reject system removes a failed product after an inspection decision and checks that the reject action occurred. Match air blast, pusher or diverter selection to the product, conveyor timing and reject destination, then define fault handling and removal confirmation for the complete inspection line.

What is an automatic reject system?
An automatic reject system removes a failed product from a production line after a vision system, checkweigher, metal detector, X-ray machine, barcode reader or process sensor issues a fail signal. A reliable system also tracks the correct product, operates the selected reject mechanism and confirms that removal was completed.
The right design depends on product weight, stability, speed, spacing, conveyor layout, cleaning environment and the consequence of a missed reject.

02 / More than a reject device
A complete, closed-loop reject architecture.
Reliable rejection depends on more than firing a cylinder. We track the failed product from the inspection point, confirm the reject device has operated and verify the product reached the secure reject area.

Practical answers before you specify.
Every line is different. These are the questions we resolve early in an automatic reject project.
Can you add an automatic reject system to our existing conveyor?+
Yes, in many cases. We survey the conveyor, product handling, available length, guarding, controls and inspection signal before recommending a retrofit approach.
How do you prove that a failed product was rejected?+
A separate verification sensor can confirm passage into the reject area. If the expected confirmation is not received, the system can alarm and stop the line.
Which reject method is right for our product?+
That depends on product mass, stability, line speed, spacing and risk. Options include air blast, pusher, swing arm, drop flap, retracting belt and lane diversion.
Can you integrate different inspection equipment brands?+
Usually, yes. We confirm the available pass/fail signals, timing, communications and responsibility boundaries during the project review.
Plan the reject sequence around the packs that are hardest to remove
The reject device must remove the failed pack while preserving the identity and movement of the products around it. Compare the mechanism, tracking and confirmation as one timed sequence.
Start with mass, stability and spacing
A light pouch, a tall bottle and a rigid case present different handling problems. Assess how the smallest and largest products react to the proposed contact or airflow, then repeat with the minimum normal gap between products. The reject-method comparison sets out the main mechanism choices.
Challenge consecutive failures
A device that removes one isolated test pack may not recover in time for the next failure. Agree the consecutive-reject cases, line-speed range and expected fault frequency. Record missed removal, disturbance of adjacent good packs and the device’s return to a ready state separately.
Confirm removal, not only device movement
A cylinder signal shows something different from a sensor confirming the pack reached the reject destination. Define what each observation proves and what happens when they disagree. Review the verification and fault-handling guide with the complete inspection-to-reject distance.
Define the restart state
When the line stops between inspection and rejection, identify products still in transit. Establish how tracked decisions, uncertain packs and the reject container are reconciled before release resumes. Include a full bin, unavailable utilities and a blocked destination in the agreed challenge plan.
Make the retrofit brief reviewable
Provide product samples, line drawings, conveyor dimensions, minimum gap, operating speed range and inspection output details. Use the integration scope to allocate mechanical access, controls, guarding, confirmation and acceptance responsibilities before requesting a quotation.
