Before diving into the design process, it's crucial to understand the basic components of a vibratory bowl feeder: Bowl: The bowl is the main part of the feeder where the parts are placed. It is typically made of stainless steel and has a helical track or multiple tracks that guide and orient the parts.

A vibratory feeder is an instrument that uses vibration to feed material through a process or a machine while controlling the rate of flow. Vibratory feeders utilize both vibration and gravity to move material forward. The force of gravity influences these parts to shift direction, causing them to move down or laterally.

Abstract— In the modern industry, vibratory bowl feeders - VBF have been widely used to feed small and light parts such as USB caps. In this method, the bowl's vibration, which caused by forced vibration and the friction between parts and track, helps convey the parts out of the feeder along the track.

The vibration will crystallize the molecular structure of the metal causing what is known as METAL FATIGUE to develop. The first sign that an operator has indicated that the fatigue in the body of the screen deck is almost at a critical stage in its development are the hairline cracks that will appear around the vibration's point of origin.

The Anti-vibration Feet or Shock Absorber There is usually a set of three or four identical rubber composite feet fitted to the underside of the main body of the bowl feeder or drive unit casting, as it is commonly known. Also, hardening of the rubber feet usually attributed to age, can contribute to poor bowl feeder performance.

The plot of vibration versus time provides information that helps characterize the behavior of the structure. Its behavior can be characterized by measuring the maximum vibration (or peak) level, or finding the period (time between zero crossings), or estimating the decay rate (the amount of time for the envelope to decay to near zero).
