Reject mechanisms
- Pneumatic pusher reject conveyors
- Air-blast rejects

- Retracting-belt rejects
- Swing-arm diverters
- Lane-divert systems
A detection is only useful if the failed pack is controlled
Automatic Reject Systems and Conveyors
Match the reject mechanism, tracking and monitoring to your product, line speed and risk—with positive confirmation that the intended pack was removed.
Reject systems
Engineer the complete reject event
The reject device must remove the correct product without destabilising adjacent packs, damaging good product or creating an unsafe access point. We combine product tracking, actuation, guarding, confirmation, bin monitoring and fault response into a defined reject strategy.

Inspection scope
What the system can cover
Each check is configured against agreed samples, tolerances and fault responses. Multiple checks can be combined into a single inspection recipe.
Monitoring
- Reject verification
- Reject confirmation sensors
- Full-bin sensors
- Air-pressure monitoring
- Fail-safe reject monitoring
- Consecutive-reject alarms
Construction
- Lockable reject bins
- Stainless-steel food-grade conveyors
- Pharmaceutical reject stations
- Guarded reject access
- Tool-free cleanable options
- Line-stop and fault interfaces

Engineering priorities
What turns an inspection into a dependable production station
- 01
Choose the reject principle from product geometry, mass, stability and line speed
- 02
Track the failed item from inspection point to reject point without ambiguity
- 03
Confirm the reject action and, where required, confirm the product entered the reject bin
- 04
Monitor air supply, bin condition, access doors and actuator readiness
- 05
Define controlled line-stop behaviour for lost tracking or an unconfirmed reject
- 06
Apply guarding, isolation and operator access controls according to the project risk assessment
From samples to sign-off
A controlled route from question to production
We reduce risk early by proving the inspection on representative products before final hardware, handling and controls are committed.
Define
Agree the pack, defect, speed, reject risk, data needs and acceptance criteria.
Prove
Run feasibility tests using representative good, bad and borderline samples.
Engineer
Design handling, cameras, lighting, controls, guarding and rejection as one station.
Integrate
Build, validate, install, train and support the system in production.

Questions answered
Reject systems FAQs
Need an answer for your exact product or line? Send us the application details and we will identify the next useful test.
Ask an application questionWhich reject system is best for my product?
Pushers suit many stable packs, air blast suits light products, drop flaps and retracting belts suit unstable or delicate packs, and diverters suit controlled lane transfer. We test the pack at the intended speed before final selection.
What is reject verification?
Reject verification uses sensors and control logic to confirm that the reject mechanism operated and, where required, that the failed product left the accepted-product path.
Why use a lockable reject bin?
A lockable bin helps control rejected product, supports line-clearance procedures and prevents unauthorised retrieval. Its need and access method depend on the production risk.
Can a reject conveyor be retrofitted?
Yes, provided there is enough controlled conveyor length and access for guarding, sensors, the reject device and bin. We survey line height, speed, controls and product spacing first.
