Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to the structure of a hopper filling port in an auger type powder filling machine.

[0002]

[Prior art]

 Conventionally, when the powder is filled into the container, unless the air contained in the powder is removed, the powder has a large specific volume, which causes a drawback that it overflows outside the container during filling. It is necessary to continuously fill the powder while deaerating the powder, and the applicant of the present application has found that the powder deaerating device (actual (See Japanese Patent Application No. 4-70552).

Therefore, when the applicant of the present invention develops an auger-type automatic powder filling machine having a further excellent vacuum deaeration effect, the applicant reduces the area near the filling port of the hopper, that is, the powder discharging port. It was discovered that resistance to the powder flow causes the powder to tighten, increasing the filling level in the screw, and further increasing the vacuum degassing effect.

[0004]

[Problems to be solved by the device]

 Therefore, the present invention is to provide a hopper filling port in an auger type automatic powder filling machine which is further excellent in vacuum deaeration effect.

[0005]

[Means for solving problems]

 An embodiment of the present invention will be described below with reference to the drawings. In an auger type powder filling machine, the side surface near the filling port at the tip of the hopper is made of a breathable material, and the periphery thereof is covered with a casing. The casing communicates with a vacuum deaerator, and the vacuum deaerator is operated to deaerate the air contained in the powder to be filled near the filling port at the tip of the hopper. It is composed of a structure of a hopper filling port in an auger type automatic powder filling machine equipped with a deaerator characterized in that a powder resistance member is provided at the tip of an auger located at the tip of the auger.

[0006]

[Action]

 This device has the above-mentioned structure, and immediately before the powder is filled into the container from the hopper by the auger at the time of filling, the vacuum deaerator is operated to remove the air in the powder near the filling port. Degassing is performed by installing a powder resistance member near the filling port (the tip of the auger located at the tip of the hopper), and by giving resistance to the powder flow, the powder is tightened and the screw fills up. If the powder is clogged with a breathable material, the auger is stopped and the pulse air is blown while the shutter is closed. Resolve.

[0007]

【Example】

 Next, the best embodiment of the present invention will be described in detail. In the auger type powder filling machine, the side surface near the filling port (2) at the tip of the hopper (1) is , A breathable material (3), the circumference of which is covered with a casing (4), the casing (4) communicates with a vacuum deaerator (5), and the vacuum deaerator (5) is activated. In the powder deaerator that deaerates the air contained in the filled powder near the filling port at the tip of the hopper, the powder is added to the tip of the auger (6) located at the tip of the hopper (1). It is configured by providing a resistance member (7).

Although a concrete structure of the powder resistance member (7) is shown, it is not limited to that shape, and the powder resistance member (7) is not limited to that shape and can be fixed by screwing or welding. It is fixed to the tip of the clew, (8) is a shutter and an exhaust hood, (9) is a container, and as an example of the breathable material (3), a mesh of about 5 microns or a sintered metal. Etc. may be used, and there is no particular limitation as long as it is a material capable of leaving powder and sucking only air.

[0009]

[Effect of device]

 According to this invention, when the powder in the hopper is filled, vacuum deaeration is continuously performed near the filling port, which is the passage with the smallest cross-sectional area. Degassing efficiency is much better than that of, and a powder resistance member is provided at the tip of the auger to resist the flow of powder, which tightens the powder, increasing the filling of the screw, and increasing the vacuum. The deaeration effect is further enhanced, and the clogged powder of breathable material can be continuously used by eliminating the auger after filling and weighing, and by blowing pulse air with the shutter closed. It has an extremely beneficial effect.
