Cap sorting

Bottle cap sorters for capping lines.

Sort, reject and present bottle caps before they enter the capping-machine chute or placement point.

Need the feeder to match your cap and capper?

Send cap samples, photos, target output and the downstream capping machine details. The quickest shortlist starts with real parts, not a generic speed figure.

Specification focus

Sorting removes the caps the capper cannot use.

A bottle cap sorter improves reliability by preventing wrong-way caps, bridged caps or unsuitable orientations from reaching the capping head. It may be integrated into a bowl feeder or supplied as part of a separate feed path.

The sorter has to be designed around the physical features of the cap. Skirt depth, tamper band, top profile and centre of gravity all affect whether the cap can be sorted mechanically.

For high-speed or repeatable production, sorting should be assessed together with chute control and capper start-stop signals.

Wrong-way cap rejectionPrevent incorrectly presented caps from entering the capper.

Stable sorted queueKeep the right caps moving without overloading the chute.

Sample-based assessmentUse real closures to confirm the sorting route.

Selection table

Key checks before specifying the feeder.

Check	Why it affects the design	What to send
Cap features	Sorter design needs a clear feature or imbalance.	Send cap samples from several batches.
Rejection route	Rejected caps must return or discharge safely.	Confirm line layout and guarding needs.
Capper speed	Sorter output must exceed actual demand.	Send production speed target.

FAQs

Questions about bottle cap sorters.

What is a bottle cap sorter?

It is equipment that sorts and presents caps in the correct orientation before capping.

Is a sorter different from a bowl feeder?

A sorter may be integrated into a bowl feeder or used as a separate orientation stage.

Can a sorter fix every cap feed problem?

No. Hopper behaviour, chute design and capper handover must also be considered.
