Abstract
A quantitative discharge apparatus for powder material, comprising: a tubular body for storing powder material; and an elastic membrane having plural penetrating apertures, the membrane constituting a bottom of the tubular body. The elastic membrane is vibrated by applying a positive pulsating vibration air, and thereby discharging powder material stored in the tubular body from the penetrating apertures of the elastic membrane. The plural penetrating apertures of the elastic membrane are formed on the circumference of a circle, of which center is a specific point of the elastic membrane.
Claims34
A discharge apparatus for powder material, comprising:
- a tubular body for storing powder material;
- and
- an elastic membrane having plural penetrating apertures, said membrane constituting a bottom of said tubular body;
- wherein said elastic membrane is vibrated by applying a positive pulsating vibration air thereto in a manner that the vibration node appears at the periphery of the elastic membrane, and thereby discharging powder material stored in said tubular body from said plural penetrating apertures of said elastic membrane.
A method of discharging powder material comprising the steps of:
- storing powder material in a tubular body to which an elastic membrane with plural penetrating apertures is attached so that it constitutes a bottom of said tubular body;
- vibrating said elastic membrane by applying positive pulsating vibration air thereto so as to make said elastic membrane vibrate in a manner that the vibration node appears at its periphery, and
- thereby discharging said powder material stored in said tubular body from said plural apertures.
