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.

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.

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.

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.

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.
