Pneumatic pusher
Positive lateral removal for stable products with suitable spacing.
Controlled removal of failures
Reject systems for failed label inspections
Track every failed pack from the inspection point and remove or contain it using a reject method suited to the product and line.

Detection to containment
A complete reject sequence
The controller associates the inspection result with the physical pack, tracks it to the reject point and confirms the expected action. The design accounts for pack speed, spacing, stability, weight and the consequence of a missed reject.
- Pack tracking between camera and reject
- Reject actuation timed to line movement
- Reject confirmation and fault handling
- Secure collection and bin-level options
Reject methods
Match the device to the product
Air blast
Fast non-contact diversion for light products where containment is controlled.
Drop flap or retract belt
Downward removal for unstable or difficult-to-push formats.
Line stop and alarm
Controlled intervention where automatic removal is unsuitable.
Fail-safe options
Design around the consequence of failure
Higher-risk applications can add assurance beyond a basic reject output.
Reject confirmation
A sensor confirms the failed product passed into the reject route.
Bin-full monitoring
Production is alerted before containment capacity is lost.
Air-pressure monitoring
Pneumatic health is supervised where loss of pressure would defeat the reject.
Locked reject collection
Access-controlled containment supports controlled disposition of failures.
