Vibrating hui - uses da the powder granule discharge device

摘要

PURPOSE:To shorten the rise time of operation of an apparatus, to speed up the discharge work, and to improve the accuracy by observing the relation of the control input such as vibration frequency or the like to the flow velocity of granular powder, correcting the relation to be linear, and controlling the control input according to the linear data. CONSTITUTION:A correction value of a storage portion 5 is applied to the curve relation 1 of the observed values of vibration frequency of a vibration feeder 2 and flow velocity to correct the relation to be converted into a straight line 2. According to the straight line 2, the first frequency is set. At this time, the frequency set according to the straight line 2 according to the flow characteristic of granular powder measured by previously executed test discharge is multiplied by a correction value (n) of a correction circuit 13 to set the final frequency. According to the frequency, the vibration feeder 2 is driven.
