Abstract
A bidirectional vibratory feeder for transporting objects in a curved path has a trough assembly including an elongated, generally horizontal bed defining the curved path, and a center of gravity. Resilient isolators are connected to the trough assembly and adapted to isolate the trough assembly from underlying terrain. An exciter mass assembly includes an exciter frame and a vibration generator coupled to the exciter frame for generating vibratory forces, the exciter mass assembly having a center of gravity. At least one horizontally disposed resilient coupling is connected between the exciter mass assembly and the trough assembly, and at least one vertically disposed link is connected between the exciter mass assembly and the trough assembly. The vibratory forces generated by the vibration generator include a vertical component directed along a substantially vertical path that passes through a combined center of gravity of the trough assembly and the exciter mass assembly that is transferred by the at least one vertically disposed link to cause each point on the trough assembly to translate vertically upward. The vibratory forces also include a horizontal component that is transf…
