There is a known powder quantitative supply device in which a powder is contained in a rotating airtight casing and a carrier gas is introduced and discharged from a feed nozzle. The carrier gas introduced into the casing by the introduction of the carrier gas into the casing flows into the outlet of the feed nozzle, which is the outlet. At that time, a suction force is generated according to the gas inflow rate, the surrounding powder is sucked together, and is conveyed to the target site through the conveyance pipe connected to the other end of the feed nozzle through the passage in the feed nozzle. To be done.

えばキャリアーガスは流出口へ流入するが粉体の取込み
ができず、いずれの場合も供給不能となる。If the tip of the feed nozzle enters the powder too deeply, the carrier gas is blocked by the powder and cannot flow into the outlet, and if the tip escapes above the surface of the powder, the carrier gas is discharged. Although it flows into the outflow port, the powder cannot be taken in, and in any case, the powder cannot be supplied.

が脱落した場合には粉体流出口を閉塞させ供給を停止さ
せるトラブルが生じる。Particularly, in the conventional apparatus, the tip of the feed nozzle constantly pushes the lower layer portion of the powder moving toward the powder outlet of the feed nozzle. Therefore, in the case of powder having poor fluidity, it tends to adhere to the surface of the feed nozzle, and when adhered powder falls off, there arises a problem that the powder outlet is closed and supply is stopped.

る。Depth from the surface of the powder which becomes impossible to supply,
Alternatively, the height from the powder surface changes depending on the properties of the powder. Even if the position can be changed, the amount of powder that flows out also changes. Therefore, to keep the outflow constant,
A feed nozzle position adjusting mechanism that can adjust the tip position of the feed nozzle according to the position of the surface of the powder is required.

定量供給装置の提供にある。Further, if the horizontal position of the tip of the feed nozzle cannot be changed with respect to the powder, the powder near the tip of the feed nozzle will eventually disappear and the outflow will stop. Since a powder quantitative supply device is required to supply powder continuously for a certain period of time, in order to achieve this, the tip of the feed nozzle continuously changes its position in search of new powder. It is desirable to have a drive mechanism that is provided. The object of the present invention is to supply powder with good fluidity and powder with bad fluidity in the same device, and to effectively prevent unnecessary force from being applied to the powder, and to ensure agglomeration of the powder. It is to provide a constant quantity powder supply device capable of preventing the above.

By always setting 1 to a fixed position near the surface of the powder P, the linearity between the supply amount of the powder P and the rotation speed of the cassette container 11 becomes extremely good. Generally, the heavier the specific gravity of the powder P, the poorer the fluidity, the closer it is to the surface, and the lighter the fluidity, the deeper it becomes, but the range is 0.5 mm on the surface.
A range of 3 mm below the surface is an appropriate level.

搬送量を適性に調整する。As described above, the powder carrying amount is usually proportional to the rotation speed of the cassette container 11 if the flow rate of the argon gas is constant, but the reproducibility may be poor depending on the property of the powder P. . The rotation speed control unit 62 is supplementarily used for feedback control in such a case. That is, the rotation speed of the turntable 21 is adjusted according to the weight reduction rate of the powder P per unit time, and the amount of the powder P conveyed is adjusted appropriately.
