The challenge
What needed to change.
Misshapen or broken biscuits could cause downstream packaging stoppages, while manual inspection could not provide consistent coverage at line speed.

Adbro’s approach
How the solution was engineered.
Adbro introduced controlled image capture and automated rejection to inspect product continuously without disrupting the existing production flow.
The outcome
What the project delivered.
Product quality is checked consistently before packaging, reducing stoppages caused by unsuitable biscuits entering the machinery.
Technical delivery
Inside the engineered solution.
The detail below shows how the main equipment, software and interfaces were brought together—not just what the project achieved.

System scope
- Six-camera inspection array
- Encoder-synchronised image triggering
- Two linear white LED lighting arrays
- Bespoke image-stitching and measurement software
- Recipe and tolerance management through the HMI
- Tracked pull-nose conveyor rejection
- Database logging and production reports
Full-belt image formation
Six individual camera views are corrected for perspective and stitched into one conveyor image, giving the inspection software a consistent coordinate system across the full belt width.
Speed-independent acquisition
An encoder provides the trigger reference so image capture follows belt movement. This maintains continuous coverage when conveyor speed changes and keeps product position available for downstream tracking.
Dimensional inspection
Each product is assessed for length, width, area, angle and deviation from the required shape. Operators can manage product-specific pass limits through controlled recipes.
Tracked rejection and reporting
Failed products are tracked to a retracting pull-nose conveyor, which removes them without stopping good production. Inspection results are stored for line-performance and quality reporting.
Verification & handover
The completed system was proven across the customer’s three product types, with checks covering continuous belt coverage, measurement repeatability, product tracking, timed rejection, recipe changeover and production-data capture.
