<p>A vibratory conveying apparatus (10;100;200) including a material carrying member (12;112;212) having a material supporting surface (14;114) is disclosed. The apparatus includes first and second vibrators (16,20;116,120;216,220) for producing first and second vibratory forces (F1,F2) for imparting movement to the material carrying member (12;112;212) at first and second acute angles to the material supporting surface (14;114). The vibratory forces (F1,F2) of the first and second vibrators (16,20; 116,120;216,220) each have a vertical force component (FV1,FV2) as well as a horizontal force component (FH1,FH2) for imparting movement to a material on the material supporting surface (14;114) in first and second directions relative to the material supporting surface (14;114). The apparatus (10;100;200) also includes an actuator for controlling the first and second vibrators (16,20;116,120;216,220) in such manner as to impart controlled movement to the material relative to the material supporting surface (14;114) in the first direction, the second direction, or vertically. In a preferred embodiment, the vibratory conveying apparatus (10;100;200) is able to vary the angle of attack and direction of the material relative to the material supporting surface (14;114). <IMAGE></p> |
