DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a powder filling apparatus, and more particularly to a powder filling apparatus for filling powder such as toner, medicine, cosmetics, foodstuffs, etc. into a powder filling container.

[0002]

2. Description of the Related Art Conventionally, various powder filling apparatuses for filling powder into a powder filling container are known. As a general one, a rotating and rotating auger with a spiral blade attached to a rod-shaped rotating shaft is used to measure and extrude powder while rotating. In the conventional example shown in FIG. 9, the powder filling apparatus 100 includes a hopper 101
The powder (P) inside is measured and extruded by the rotation of the auger 102, and the powder supply port 1 is fed through the funnel 101a.
03, the powder filling container 104 is filled. The powder filling container 104 filled with the powder (P)
When the powder is a toner for a copying machine or a printer, a cartridge may be used. When the powder is a cosmetic or food, a glass or plastic bottle may be used, or a plastic bag may be used. The powder (P) is once put into a hopper 101 having an auger 102 from a larger hopper or a storage container, and then the hopper 1 is rotated by rotation of the auger 102.
A specific amount is charged into the powder filling container 104 on the belt conveyor 105 through the funnel 101a through the opening 101b at the bottom of the container 01. Each of the powder filling containers 104 moving on the belt conveyor 105 is weighed before filling, and based on the data, the number of rotations of the auger 102 is controlled by the number of rotations of the motor 106, so that a certain amount is obtained. Is filled with the powder (P). After filling, the weight of the powder filling container 104 is measured again, and the weight is measured based on the difference from the previous tare.

In such a method, it takes time for the powder (P) to settle in the filling container 104, and the filling is inefficient and the packing cannot be performed at a high density. Therefore,
Instead of allowing the powder to settle naturally in the powder-filled container,
Immediately after starting the work of filling the powder into the powder filling container, the air is supplied from the filling hopper or the funnel to the powder filling container from the air supply pipe and the air supplied from the air-permeable inner wall, etc. After a certain amount of powder has been filled into the powder filling container so that the powder can smoothly flow into the powder filling container, the powder in the powder filling container is filled with the powder. The powder contained in the powder filling container is sucked from the air separation unit that separates the air contained in the powder from the powder, and the powder content in the powder filling container has a low air content. As the height increases, the filling amount of the powder increases, the time required for the filling decreases, and the powder and air are actively separated to increase the work efficiency of the filling operation. Filling with powder is known (JP See JP-A Nos. 8-198203). In addition, in filling the powder into the powder filling container, after the inside of the powder supply means and the powder filling container is pressurized, the pressurized air in the powder supply means and the powder filling container is discharged. Then, the powder supply means and the inside of the powder filling container are returned to the atmospheric pressure, so that the powder is filled in the powder filling container, and the bulk density of the filled powder in the powder filling container is increased. ,
It is also known to improve the efficiency of filling a powder into a powder container (see Japanese Patent Application Laid-Open No. 9-104401).

In FIG. 10 and FIG. 11, in such a powder filling apparatus 200, a funnel 201 is detachably connected to a powder supply port 203 of a wide-mouthed powder filling vessel 202, and air is contained in the funnel 201. A suction pipe 204 is provided,
An air separation unit 205 for separating air (A) from powder (P) is attached to one end of an air suction pipe 204 extending into the powder filling container 202, and the air extending outside the funnel 201. The other end of the suction tube 204 is connected to a pressure reducing source 206. Here, the filling operation of the powder (P) into the powder filling container 202 is performed through the funnel 201.
Is supplied into the powder filling container 202 and a predetermined amount of powder (P) is supplied.
Is supplied into the powder filling container 202, and then the
6 to drive the air in the powder filling container 202 into the filter 205a and the hole 205b of the air separating unit 205.
Through the air suction pipe 204
The air (A) is sucked in and discharged out of the powder filling container 202. The powder filling container 20
After the filling operation of the powder (P) into the inside 2 is completed, the air suction pipe 204 is removed from the powder supply port 203 together with the funnel 201, and the powder supply port 203 is closed with a cap (not shown). I have. However, these powder filling devices are capable of filling powder at high speed by actively separating powder and air by air flow, decompression and pressurization.
Although the density was increased, the structure of the funnel became complicated due to the supply pipe for supplying air and the air-permeable inner wall, etc., which increased the cost and the size of the funnel. The density is unstable due to variation, the amount of powder cut out and the amount of filling are also unstable, and the replacement speed of powder and air at the powder supply port in the powder filling container is slow, and the falling speed of powder is also slow. However, the filling of the powder has not been carried out with sufficiently high speed and high density.

[0005]

The conventional powder filling apparatus is capable of filling powder at high speed and high density by positively separating powder from air by air flow, decompression or pressurization. However, the structure of the funnel is complicated by the supply pipe for supplying air and the air permeable inner wall, etc., which increases the cost and size, and the bulk density of the powder filled in the powder filling container is reduced. It is unstable and unstable, and the cut-out amount and filling amount of the powder are also unstable.The replacement speed of the powder and the air at the powder supply port in the powder filling container is slow, and the falling speed of the powder is slow. There has been a problem that the body is not filled at a sufficiently high speed and high density. Therefore, an object of the present invention is to
This problem is solved. In other words, the filling of the powder is stable and the cut-out amount and the filling amount of the powder are stable and high enough,
