This is a training device consisting of a feeder that stores parts.

It is a type known as a “pouch-type” or gravity feeder. The parts appear to be stacked on top of each other, so that when the bottom part is fed, the others fall by their own weight. The base is extracted using a pneumatic cylinder, which pushes a pusher appropriately aligned with the base’s profile to the part’s verification area. This checks the part’s correct position; if it is incorrect, the part is rejected by an ejector cylinder.
