Automatic failed-pack rejection

Remove failed packs—and prove the rejection happened

Match the reject mechanism, tracking and verification to your product, conveyor, line speed and risk controls.

The inspection challenge

A pass/fail decision only matters if the right pack is removed

Reject design covers more than an actuator. Pack pitch, conveyor speed, product stability, accumulation, fail-safe behaviour, reject confirmation and bin access all affect whether the complete system performs reliably.

  • Air-blast and pneumatic pushers
  • Drop-flap and retracting-belt rejects
  • Diverters and line-specific mechanisms
  • Encoder-based product tracking
  • Reject confirmation sensing
  • Full-bin, bin-present and door monitoring
Production outcomes

Designed to make every decision useful

01

Reject the right product

Track each inspection result from camera trigger to reject point.

02

Detect reject faults

Confirm actuation and product removal rather than assuming success.

03

Support fail-safe control

Define alarm and line-stop behaviour for sensor, air, bin and communications faults.

Application framework

What the system can include

Final scope follows trials and a line survey. The table shows the main engineering considerations for this inspection type.

Selection factorsPack weight, stability, spacing, speed, conveyor geometry and reject destination
TrackingTimed, encoder-based or PLC-controlled depending on line dynamics
VerificationReject confirmation, bin level/presence, door status and consecutive-failure logic
ControlsHardwired I/O, industrial network or coordinated line PLC interface
A controlled route to production

From sample pack to validated inspection point

Reliable inspection begins with realistic defects and finishes with the line proving that the correct failed pack was removed.

01

Define the fault

Agree the pack, line speed, critical seal area and pass/fail tolerance.

02

Prove the image

Trial representative good packs, known failures and normal production variation.

03

Engineer the station

Specify handling, optics, lighting, controls, guarding and reject method.

04

Integrate & validate

Install, commission and test the complete inspection and rejection sequence.

Practical answers

Seal inspection questions

Clear answers before you invest in an in-line inspection project.

Which reject system is best for trays?

It depends on tray mass, stability, line speed and available space. Pushers, drop flaps, belt withdrawal and diverters are common starting points.

What happens if a failed pack is not rejected?

Where reject confirmation is specified, the control system can alarm and stop the line according to the agreed fail-safe sequence.

Can you add inspection to an existing conveyor?

Often, yes. A site survey confirms space, access, guarding, electrical controls and whether conveyor modifications are required.

Application guidance

Validate the pack decision all the way to the reject bin

Tracking, confirmation, bin monitoring and fail-safe response should be included in acceptance and cost planning.
