Stable weighing
Infeed control, transfer design and belt speed selected to protect measurement integrity.
Dynamic weighing & reject handling
Checkweigher reject systems engineered around your pack
Remove underweight and overweight packs without creating secondary line problems. We integrate checkweighers with the right reject device, product control, guarding and verification.
Representative engineered production applicationThe inspection result is only useful when the right product leaves the line.
A checkweigher needs consistent infeed spacing, a stable weighing section and enough downstream distance to reject the correct pack. Oxford Vision Systems reviews the complete handling path rather than treating the reject device as an isolated accessory.
Light pouches may suit air blast, while cartons, jars and heavier products often need a pneumatic pusher, swing arm or powered diverter. High-care and pharmaceutical applications can include lockable reject bins, full-bin monitoring, access supervision and challenge-test routines.
How our integration works →Typical pass / fail criteria
Decisions the reject system can act on.
The final inspection capability depends on the selected equipment, product presentation and agreed acceptance criteria. Sample trials are used where practical.
✓Underweight packs
✓Overweight packs
✓Missing product or component
✓Filler giveaway trend
✓Tare or product mismatch
✓Consecutive weight failures
Engineered as one sequence
From detection signal to independently confirmed removal.
Pack-specific reject
Reject type and timing sized for product mass, footprint, stability and throughput.
Secure accountability

Product samples, line drawings and a short production video help us identify the best next step.
Which reject type works with a checkweigher?+
It depends on pack weight, stability, speed and available line length. We assess air blast, pusher, drop flap, swing arm and diverter options.
Can you link the system back to a filler?+
Where supported, weight trends or control signals can be used for filler feedback. The required interface is agreed with the equipment supplier.
Do you provide secure reject bins?+
Yes. Lockable bins, access switches and full-bin sensing can be included where the risk assessment requires controlled rejected product.
