Cap and closure
Missing, proud, skewed or incorrect caps; tamper-band presence; closure colour and orientation.
Rigid-container inspection and removal
Automatic reject systems for bottles, jars and cans.
Remove the exact failed container after cap, label, date-code, barcode, fill-level, leak or weight inspection—without upsetting adjacent good products.
Direct answer
What is the best reject method for bottles and jars?
A guided pusher, sweep arm or lane diverter is normally the starting point for stable rigid containers. The correct choice depends on container height, weight, centre of gravity, line speed, gap and whether the pack can tolerate side contact.
Light or empty containers need particular care because a reject action can disturb neighbouring products. We prove the complete sequence with representative samples and realistic line conditions.
Inspection triggers
Label and code
Label presence and position, artwork match, barcode readability, date and batch-code verification.
Fill and weight
Underfill, overfill, missing components and gross-weight checks from sensors or checkweighers.
Container quality
Damage, deformation, contamination, neck faults and other visible defects detected by cameras.
Seal and leak
Pressure decay, vacuum, squeeze, high-voltage or vision-based seal inspection results.
Traceability
Wrong-SKU, no-read or mismatched 1D, 2D, QR and Data Matrix codes tracked to rejection.
Stable product handling
One controlled sequence from inspection to containment.
Separate
Maintain a reliable product window so one failure does not become a multiple reject.
Track
Follow the failed container from the inspection point to the reject position.
Remove
Apply the correct force and motion for the pack geometry and speed.
Verify
Independently confirm that the expected container entered the reject area.
Contain
Use a guarded or lockable reject route where product control requires it.
Information needed for a bottle-line review.
Send the smallest and largest container, empty and filled weight, line speed, minimum gap, conveyor width and height, current inspection equipment, reject-side space and a short production video. Include the least stable format and any wet, dusty or washdown conditions.
New lines and retrofit projects
The system can be designed with a new conveyor or integrated into an existing customer conveyor. Retrofit feasibility depends on mechanical condition, available length, drive control, signal access, guarding and responsibility for the existing machine.
Common questions
Bottle and container reject answers.
Final performance is confirmed against the actual product range and production conditions.
How do you avoid knocking over good bottles?+
We control spacing and guides, shape the contact face and prove pusher speed, stroke and return timing across the operating range.
Can the reject handle glass jars?+
Yes, subject to a risk review and trials. A controlled pusher or guided diversion is generally preferred over an uncontrolled drop.
Can rejected containers be separated by fault type?+
Potentially. Separate reject lanes or bins can be used where inspection results and available space support fault segregation.
What happens if a reject is not confirmed?+
The system can alarm and stop the line, preserving the fault until an authorised operator follows the agreed recovery procedure.
