Bulk storage must still feed caps in a controlled way.
A hopper cap feeder gives operators more capacity than a small cap bowl or manual chute. It can be useful where the capper needs a steady supply over longer production runs.
Hopper design must prevent bridging, overfilling and uncontrolled cap flow. A hopper may feed an elevator, a bowl feeder, a sorter or directly into a controlled route depending on the cap and line speed.
Level sensors help the feeder start and stop at the right time so the chute remains full without flooding the capper.
