OSCILLATING TYPE PART FEEDER

PURPOSE:To easily change oscillation frequency by way of changing the number of rotation of a motor by constituting an oscillating source of a rotor rotated by the motor and a stator provided adjacent to it and forming the rotor of a magnet having polarity CONSTITUTION:In a rectilineal feeder (part feeder), a base 1 is placed on an installation board 3 free to move by four pieces of rubber feet 2, a pair of plate springs 4, 5 inclined at a specified angle is installed through installation plates 6, 7 on this base 1, and upper ends of the plate springs 4, 5 are fixed on an oscillating body 10 provided with a trough 11. Additionally, on an upper surface central part of the base 1, a variable speed motor 12 is erectly provided, on an upper end part of the rotation axis of the motor, a rotor 13 consisting of a rotating member made of a permanent magnet is fixed, and simultaneously, on the lower surface of the oscillating body 10, adjacent to the outer peripheral surface of the rotor 13, a stator 14 made of a permanent magnet in the same way is fixed. By periodically generating attracting force and resiliency between the oscillating body 10 and the stator 14 by rotation of the rotor 13, the oscillating body 10 is oscillated.
