Reversing conveying brute force vibratory feeder

A vibrating conveyor, powered by a reversible motor, for moving a conveyor trough in a first direction along a non-linear path when said motor is operating in the forward direction, and for moving said conveyor trough in a second direction along an essentially symmetric non-linear path when said motor is operating in the reverse direction, said conveyor comprising

• said conveying trough for moving product through vibratory motion imparted to said trough;
• a stationary frame;
• a plurality of spring members mounting said trough on said frame;
• and
• a vibrating assembly for imparting vibratory motion to said trough, said assembly comprising three essentially parallel shafts, defining two outermost shafts and an intermediate shaft, adapted to be rotated to generate said vibratory motion, each of said shafts having an eccentric weight fixedly attached to said shaft, each of said weights having essentially the same mass and being positioned on said shafts so that the angular orientations of said weights on the outermost shafts are essentially the same throughout a 360° rotation of said shafts;
• and a drive means, including a reversible motor, for rotating said shafts such that the outermost shafts and associated weights rotate in the first direction and the intermediate shaft and associated weights rotate in the second direction opposite to the first direction of the outermost weights.

• and a drive means including a reversible motor for rotating said shafts such that the outermost shafts and associated weights rotate in the first direction and the intermediate shaft and associated weights rotate in the second direction opposite to the first direction of the outermost weights.
