ABSTRACT:
A reversible vibratory parts feeder including a feeder bowl with an upwardly inclined spiral ramp mounted on a generally circular base. The base is flexibly supported on a massive mounting plate by a plurality of leaf springs extending angularly upward from the mounting plate and arranged in a circular, symmetrical array about the axis of the base. An electromagnetic motor is mounted on the mounting plate directly beneath the base in cooperating relation with an armature attached to the bottom of the base for causing oscillating vibratory movement of the base and the feeder bowl in a path of travel with both vertical and angular components as determined by the inclination of the leaf springs. The upper ends of the leaf springs are attached to the base by first reversible means pivotable about an axis extending radially from the vertical axis of the base to permit reversal of the direction of the inclination of the springs and also fine adjustment of the connection to accommodate the particular angle of inclination of the springs. The lower ends of the springs are attached to the mounting plate by second reversible means pivotable about a vertical axis and which also permit reversal of the direction of inclination. The lower ends of the springs are located radially inwardly of the upper ends to better accommodate the flexing of the springs due to angular deflection of the base during oscillating vibratory movement of the base and bowl.
