PURPOSE:To enable the part supply capacity to be augmented by configurating a device in such a way that the amplitude of a vibration part supplyer to be reduced to the maximum one out of the set amplitude not to convey a part when the part is overflowed from a part transfer unit which transfers the part to the following process, then the amplitude is returned to the original one after the part overflow has been cleared away. CONSTITUTION:When a part is forwarded to a part transfer unit 3 from a vibration part supplyer 1 so as to be carried to the following process by means of a constant amplitude control which allows the amplitude of the vibration part supplyer to be set the set value, if it is detected that the part is overflowed from the transfer unit 3 by a detecting switch 5, the amplitude of the supplyer 1 is reduced to the maximum amplitude or the value close to it so that the conveying speed of the part may be approximately zero based on the detected signal. Then, when it is detected that the condition of the part overflow in the part transfer unit 3 has been cleared away, the amplitude of vibration is switched to the set amplitude from the above said maximum amplitude or the value close to it based on the detected signal. This configuration enables the condition of the lack of part supply to the following process to be eliminated after the part overflow has been cleared away.
