Verification

Cap feeder vision and verification checks.

Cap feeder verification can confirm that the right cap is present, correctly orientated and ready for the capper before a wrong closure creates downtime or a quality issue.

Direct answer

Use verification when the line needs more than simple cap flow.

Cap feeder verification uses sensors, switches or vision checks to confirm a useful condition before the cap reaches the capping head. The condition may be cap presence, queue level, correct orientation, correct colour, correct cap type, liner visibility or whether a reject has been cleared.

The best verification point is chosen around the decision the line must make. A sensor can stop the feeder, stop the capper, release a reject, warn an operator or provide evidence for a quality check.

Verification choices

Choose a verification method from the risk.

Requirement	Possible check	Typical response
Cap queue available	Cap-in-chute or low-level sensor.	Permit capping, pause capper or request replenishment.
Wrong-way cap risk	Orientation sensor, mechanical gate or vision check.	Reject, recirculate or stop before the capping head.
Wrong cap or colour risk	Vision, colour or presence verification depending on the feature.	Stop, reject or alert for operator confirmation.
Quality evidence needed	Defined inspection point and event logging through the line control system.	Record condition or trigger a quality hold, depending on the process.

Buyer questions

Questions about cap feeder verification.

Does a cap feeder need vision or is a sensor enough?

A sensor is often enough for presence, queue or simple cap-in-chute checks. Vision becomes more relevant when the line must distinguish subtle orientation, colour, printed features, missing liners or mixed cap types.

Should verification be before or after the sorter?

Verification is usually most useful at the point where a decision can still prevent a fault. That may be after orientation, before cap release, at the chute queue or at the capper handover depending on the risk.
