Vibratory bowl feeders are common devices used to feed individual component parts for assembly on industrial production lines. They are used when a randomly sorted bulk package of components or billets must be fed into another machine one-by-one, oriented in a particular direction.

Vibratory feeders rely on the mechanical behaviour of a part, such that when shaken down a conveyor chute that is shaped to fit the part, they will gradually be shaken so that they are all aligned. They thus leave the feeder's conveyor one-by-one, all in the same orientation. This conveyor then leads directly to the following assembly or packing machine.

Orientation relies on the shape and mechanical behaviour of an object, particular the position of its center of mass in relation to its center of volume. It works well for parts such as machine screws, with rotational symmetry and a clear asymmetry to one heavy end. It does not work for entirely symmetrical shapes, or where orientation depends on a feature such as color. The ramps within a bowl feeder are specifically designed for each part, although the core mechanism is re-used across different parts.

The exit orientation of a bowl feeder depends on the part's shape and mass distribution. Where this is not the orientation needed for the following assembly step, a feeder is often followed by a  conveyor that guides the part to the next stage.
