Abstract

A vibratory conveying apparatus including a material carrying member having a material supporting surface is disclosed. The apparatus includes first and second vibrators for producing first and second vibratory forces for imparting movement to the material carrying member at first and second acute angles to the material supporting surface. The vibratory forces of the first and second vibrators each have a vertical force component as well as a horizontal force component for imparting movement to a material on the material supporting surface in the first and second directions relative to the material supporting surface. The apparatus also includes an actuator for controlling the first and second vibrators in such manner as to impart controlled movement to the material relative to the material supporting surface in the first direction, the second direction, or vertically. In a preferred embodiment, the vibratory conveying apparatus is able to vary the angle of attack and direction of the material relative to the material supporting surface.
