Abstract
A vibratory drive system for a vibratory conveyor apparatus is operable to selectively vary the conveying speed of the conveyor apparatus between zero, or stand-still, up to a maximum speed while the drive system is operating imparting a vibratory conveying force to the conveyor apparatus. The vibratory drive system is also operable to change direction of the conveyor apparatus between forward and reverse conveying directions also while the drive system is operating imparting a vibratory conveying force to the conveyor apparatus. In addition, the vibratory system can be adapted to provide either a linear drive force to the conveyor apparatus, or an elliptical drive force to the conveyor apparatus.
