ABSTRACT:
A vibratory feeder system includes a track having a linear, circular or helical configuration upon which articles that are to be transported are positioned. The vibratory feeder system further includes a support structure for supporting the track. The track and support structure are joined by resilient members of a configuration and dimension such that the track may move in a generally linear, reciprocative path relative to the support structure. The vibratory feeder further includes one or more self-contained, inertial drive elements wherein each drive element includes a rigid, nonmagnetic, cylindrical housing having end covers. Two iron stator cores are rigidly mounted within the housing and to the interior of one end cover thereof. Two resilient members having mounted at one end thereof a reciprocating armature are secured to the one end of the housing. A laminated iron armature core positioned so as to be spaced from the stator cores by an air gap is mounted on the armature. The stator cores upon being energized effectuate oscillatory movement of the armature. This reciprocating movement is transmitted to the housing of the inertial drive element. The inertial drive element is secured in a clamp that is rigidly attached to the track. The attachment of the inertial drive element to the clamp is such that the clamp may be loosened to allow rotational or longitudinal movement of the inertial drive element relative to the clamp and to the track. Consequently, the inertial forces imparted to the clamp are subsequently imparted to the track at a desired location and angle thereby causing a controlled oscillating movement of the track relative to the support.
