6図に示すような開状態となる。Conventionally, as a shutter having a plate-like opening / closing valve connected to a filling machine nozzle when the toner is filled in a toner container by an auger-type automatic filling machine, those shown in FIGS. 5 and 6 are used. Explaining with reference to this drawing, first, the toner supplied to the funnel 23 through the nozzle 21 by the rotation of the screw auger 22 is supplied to the lower container 30 for a certain period of time with the shutter opened (FIG. 6). . At the end of the set time, the rotation of the screw auger 22 stops, and the funnel 23 rises by several centimeters due to the action of an air cylinder (not shown). In this case, a small amount of toner adhering to the inner wall of the funnel drops and scatters due to the vibration when the funnel 23 rises. Next, the compressed gas filled in the cylinder 29 is discharged, and the plate-like on-off valve 26 of the shutter device is operated to be in a closed state (FIG. 5). At this time, part of the toner adhering to the nozzle 21 or the funnel 23 peels off again, and the plate-like on-off valve 26
Very often falls and accumulates on top. Further, when the toner container 30 is replaced with an unfilled one, the compressed gas is supplied into the cylinder 29, the plate-like opening / closing valve 26 is operated, and the open state again becomes as shown in FIG.

影響を及ぼす。Here, the toner accumulated on the plate-like opening / closing valve 26 is removed to some extent by the air constantly sucked from the air suction unit 28 of the casing 27. However, when the plate-like on-off valve 26 operates, that is, when compressed air is supplied into the cylinder 29 and the plate-like on-off valve 26 moves rapidly in the opening direction, the toner accumulated on the plate-like on-off valve 26 Fly into the atmosphere due to the impact of the movement of the body. In addition, while the above-described series of filling operations is repeated, toner adheres and accumulates in the gap between the shutter casing 27 and the plate-like on-off valve 26, and the fused and coarse-grained toner is generated, which adversely affects the quality of the toner.

[実施例] 以下、実施例にて本願発明の構成要件及び作用につき
詳述する。[Examples] Hereinafter, components and functions of the present invention will be described in detail with reference to examples.
本願発明の一実施例第1図、第2図、第3図、第4図
に示す。One embodiment of the present invention is shown in FIG. 1, FIG. 2, FIG. 3, and FIG.
本発明に係るシャッター装置は、主に板状開閉弁4、

る。The shutter device according to the present invention mainly includes a plate-shaped on-off valve 4,
An air cylinder 14 for operating the plate-like on-off valve 4,
A directional plate for uniformly dispersing the air supplied from the air inlets 8, 9 of the shutter casings 6, 7 and injecting the air into the on-off valve 4 at a certain angle with the on-off valve body surface And a suction hood 12 attached to the outer periphery of the discharge port.

し、板状開閉弁4上に落下し堆積する。The material to be filled conveyed by the rotational movement of the screw auger 2 is discharged from the lower end of the nozzle 1, passes through the funnel 3 and the shutter, and is filled in the container 15. During this time, the plate-like on-off valve 4 is in the open state (second
Figure). Immediately after the rotation of the screw auger 2 is stopped, the plate-like on-off valve 4 moves from the open position to the closed position by extracting compressed air filled in the air cylinder 14 from the cylinder (the first position). 1), and completely block the passage of the material to be filled. After that, a part of the filling material adhering and accumulating in the tip portion of the nozzle 1 or the funnel 3 is peeled off, falls on the plate-shaped on-off valve 4, and accumulates.

密閉されている為、板状開閉弁4の作動時に被充填物の
系外飛散も全く無い。Then, the filled container 15 is removed, and immediately after the new container is set at the material discharge port of the shutter, compressed air is introduced into the cylinder 14, and the plate-like on-off valve 4 is opened. Move to the position and the filling is performed again.
The pressurized air introduced from the air inlets 8 and 9 is supplied constantly or when the screw auger 2 is stopped, and is uniformly rectified by the rectifying and dispersing plate 5 formed of a directional perforated plate. It is dispersed and blows out toward the surface of the plate-like on-off valve 4 in a certain direction as indicated by the arrow in FIG. The air ejected from the rectifying and dispersing plate 5 gives an impact to the packing material deposited on the surface of the plate-shaped on-off valve 4, and is exhausted from the pressurized air exhaust port 10 in FIG. As a result, all the objects to be filled deposited inside the shutter, that is, on the surface of the plate-shaped on-off valve 4 or the surface of the rectifying / distributing plate 5, are discharged out of the shutter. Therefore, even if this operation is repeatedly performed, the material to be filled does not accumulate in the shutter, so that at least the phenomenon of fusing and coarsening to the material to be filled such as toner does not occur, and the shutter is further operated. Since the casing is sealed by the casings 6 and 7, there is no scattering of the material to be filled outside the system when the plate-like on-off valve 4 is operated.
また、第5,6図に示す従来技術で示すシャッター内に
堆積している被充填物を取り除く為に必要とする吸引空
気量と、本発明で必要とする加圧空気量を比べた場合、
加圧空気量は吸引空気量の1/2〜1/3の量で十分である。In addition, when comparing the amount of suction air required to remove the material to be filled deposited in the shutter shown in the prior art shown in FIGS. 5 and 6 with the amount of pressurized air required in the present invention,
An amount of pressurized air of 1/2 to 1/3 of the amount of suction air is sufficient.

口部の形状、開口部の開孔比に起因する加圧空気の噴出
速度、噴出角度等がある。Further, factors that affect the cleaning performance of the plate-like on-off valve surface of the shutter device of the present invention include the shape of the opening of the rectifying and dispersing plate 5, the ejection speed of the pressurized air resulting from the opening ratio of the opening, and the ejection angle. Etc.
開口部の形状は、例えば、第4図に示す様な形状とし
開口部配列は千鳥配列が良い。また、開孔比については
1〜2%、噴出角度は30゜〜60゜が良好で、噴出速度は

以上が良く、シャッターの繰り返し作動によるトナーの
飛散、融着、粗粒化は認められない。また、シャッター
に供給する加圧空気の圧力は、分散板の開孔比と噴出速
度によるが、70〜500mmAgで十分である。For a one-component toner having a particle diameter of at least 20 μm, the aperture ratio is 1.3%, the ejection angle is 45 to 60 °, and the ejection speed is 50 m / sec.
Above is good, and scattering, fusion and coarsening of toner due to repeated operation of the shutter are not recognized. The pressure of the pressurized air supplied to the shutter depends on the aperture ratio of the dispersion plate and the ejection speed, but 70 to 500 mmAg is sufficient.
