ABSTRACT:
A vibratory parts feeder has a feeder bowl with a helical track originating at the bottom of the bowl and extending upwardly along the inner periphery of the bowl wall to an exit station at the top of the bowl. Articles can be progressively fed from the lower portion of the bowl along the helical track to the exit station at a given feed rate by vibratory energy. The feeder bowl and its mounting frame form a feeder bowl mass that is supported above a base mass by a plurality of inclined leaf springs. One end of each spring is connected to the feeder bowl mass and an opposite end of the spring is connected to the base mass. The leaf springs are arranged to move one of the masses vertically in response to rotational twisting of one of the masses relative to the other mass about a central vertical axis of the feeder. A driver that is mounted on one of the masses has a plurality of rotating eccentric weights for imparting to the mass upon which the driver is mounted on oscillating rotational impulses about the central vertical axis of the feeder. These impulses cause the feeder bowl mass to rotationally oscillate about the central vertical axis and to move up and down at accelerations which permit the helical track within the feeder bowl to lose contact on a downstroke with articles being fed along the track. When contact between the track and the articles being fed is resumed on an upstroke, the articles are located in advanced positions along the track due to rotational oscillation of the feeder bowl mass.
