PURPOSE:To supply accurate amts. of powder by lifting the powder in a cylinder which is opened upward and is disposed with upward inclination by a piston and supplying the powder under excitation. CONSTITUTION:When the hammer 32 of a disc 31 rotated and driven by a motor taps a projection 29, the hammer 25 excites a cylinder 17. The powder contained in the cylinder 17 drops into a guiding cylinder 16 as a piston 19 displaces upward. At this time, the cylinder 17 is excited by an exciting means 23 and therefore the dispensing of the powder upon stopping of driving of the piston 19 is accomplished accurately. The scattering of the powder is prevented by the cylinder 16, and the powder discharged from the cylinder 17 falls accurately into a vessel 10. The vessel 10 is weighed by a weighing means 8 which is moved above a through-hole 7 by the extension of a cylinder 9. |
