Bowl feeder

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 small components must be fed into another machine one-by-one, oriented in a particular direction.[1]

Vibratory feeders rely on the mechanical behaviour of a part, such that when gently 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 centre of mass in relation to its centre of volume. It thus 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 colour. The ramps within a bowl feeder are specifically designed for each part, although the core mechanism is re-used across different parts.
