る。In this type of powder filling machine, the guide tube 3 is free from the powder chute 11 because the measuring device 6 is provided on the side of the guide tube 3 on which the bag Y is mounted. A small space M (M = about 5 mm) is formed between the powder chute outlet 11a and the upper end of the guide cylinder 3. Further, when the powder P is supplied from the powder chute outlet 11a into the bag Y through the guide cylinder 3, the powder P is a fine powder and has a small specific gravity, and because of a drop impact at the bottom of the bag. Moreover, a part of the powder P comes to float like a fog in the bag (in the guide cylinder 3). Air Q mixed with such smoky powder
A relatively large amount of powder component is mixed therein. Further, when the powder P is supplied into the bag from the powder chute outlet 11a, the air in the bag Y (in the guide cylinder 3) is replaced with the powder P, but at that time, the powder floats. The powder-entrained air Q is removed to the outside through the gap M between the powder chute outlet 11a and the upper end of the guide cylinder 3. If the powder-containing air Q is discharged to the outside as it is in this way, the raw material (powder) is lost, the surrounding work environment is polluted with the powder, and the powder is deposited on the weighing device or the like. Then, the weighing device 6 becomes 0
This causes problems such as a point abnormality, and the powder adheres to the bag attachment detection sensor (photoelectric tube) to make it impossible to detect the presence or absence of the bag.

えがないものである。By the way, the air / powder suction port and the suction port are adjacent to each other in the inner and outer directions through the intermediate cylinder wall, but the upper end of the guide cylinder having an inner diameter substantially the same as the inner diameter of the intermediate cylinder wall is connected to the intermediate cylinder. Since it is located close to the lower end of the wall, the air / powder suction port and the intake port are partitioned in a state where the lower end of the intermediate cylinder wall and the upper end of the guide cylinder are communicated with each other by a small distance. The air / powder suction port is inside the intermediate cylinder wall and the guide cylinder and sucks only the powder-containing air in the bag (in the guide cylinder), while the intake port is outside the intermediate cylinder wall and the guide cylinder. Therefore, the outside air is mainly sucked. Therefore, since the outside air does not enter from the air / powder suction port on the inside, only the powder-containing air that is still clean (no dust is mixed) is sucked in.
Only the outside air containing almost no powder component is sucked from the outside air intake port. Also, when the outside air is sucked from the outside intake port, even if the powder-entrained air generated in the bag goes out through the gap between the lower end of the intermediate cylinder wall and the upper end of the guide cylinder, the outside air is sucked from the intake port. As a result, the leaked powder-containing air is sucked from the intake port, and the powder-containing air is not scattered to the outside. or,
The powder-containing air having a high powder content which is sucked from the air / powder suction port inside is separated from the air by the air / powder separation device. The powder separated in the air / powder separator is in a clean state (no dust is mixed) and can be packed as a product as it is without any problem.

を大幅に少なくすることができる。On the other hand, a slight amount of powder component is mixed in the intake air sucked from the outside intake port (for example, about 0.4% or less of the amount of powder filled in the bag). The entrained air is introduced into another air / powder separator where the powder is separated. It should be noted that the powder separated here contains dust in the outside air and needs to be re-refined before it can be used as a product, but the amount of powder collected here is smaller than in the past. The number of operations for re-refining can be significantly reduced.

く次工程において製品として袋内に充填される。According to the second aspect of the invention, as in the case of the first aspect, only the powder-containing air which is still clean is sucked from the gas-powder suction port. It is directed into a separator where the powder is separated from the air.
Then, the powder separated in the air / powder separator is automatically returned to the powder supplied into the powder chute by the powder returning device, without any special transfer work. In the next step, the product is filled in the bag.

る。According to the third aspect of the invention, since the annular spacer is provided between the outer end of the powder chute outlet and the inner end of the gas / powder suction port, the width of the spacer is outside the powder chute outlet. The distance between the end and the inner end of the air / powder suction port becomes wide, and it becomes difficult for the high-density powder immediately after being discharged from the powder chute outlet to be directly sucked to the air / powder suction port side. Therefore, the total amount of powder components sucked toward the air / powder suction port side is reduced.

ることなくそのまま利用できるという効果もある。According to the first aspect of the present invention, the inner diameter of the intermediate cylinder wall which divides the air / powder suction port and the suction port is made substantially the same as the inner diameter of the guide cylinder for mounting the bag, and Since the lower end of the intermediate cylinder wall and the upper end of the guide cylinder are arranged close to each other with a small gap, the lower positions of the air / powder suction port and the intake port are partitioned inward and outward by the guide cylinder. Then, when the powder filling work is performed while sucking with the suction device from the air / powder suction port and the suction port, respectively, when the powder is supplied from the powder chute outlet into the bag (in the guide cylinder), Almost all of the powder-mixed air replaced by is sucked from the air / powder suction port inside, and the powder-mixed air is hardly sucked to the intake port side that sucks the outside air. Therefore, it is possible to significantly reduce the amount of the powder containing impurities to be re-refined later, reduce the number of operations for re-refining the powder, and reduce the work cost for the re-refining. effective. Further, according to the invention of claim 1, as described above, since the lower end of the intermediate cylinder wall and the upper end of the guide cylinder are close to each other with a small gap, the air mixed with the powder sucked from the air / powder suction port is outside air. There is also an effect that impurities in the inside will not be mixed, and the powder separated from the air mixed with powder in the air / powder separator can be used as it is without being re-refined.

That is, the powder in the air containing the clean powder that is sucked from the air / powder suction port is separated from the air in the air / powder separator. Since it is automatically returned to the powder chute side by the body returning device, it is not necessary to transfer the powder.

離・堆積される。On the other hand, since the suction devices 21 and 41 are operating, they are generated in the bag Y (in the guide tube 3) from the air / powder suction port 44 of the powder recovery device 4 as shown by an arrow A. The powder-containing air Q is sucked, and the outside air is sucked from the intake port 26 of the powder scattering prevention device 2 as shown by an arrow C. Therefore, the powder-containing air Q replaced with the powder P in the bag Y is sucked into the vacant chamber 48 from the air / powder suction port 44,
Further, as indicated by reference numeral Q 1 ,
The powder component is sucked into the powder separator 42, and the powder component is separated there. In this way, the powder P 1 separated in the air / powder separator 42 is sequentially deposited on the bottom of the air / powder separator 42. On the other hand, since the outside air is continuously sucked from the intake port 26, the powder-containing air Q generated in the bag is generated.
Does not scatter to the outside and does not pollute the surrounding environment. In particular, since the vertical distance M between the upper end of the guide cylinder 3 on which the bag Y is mounted and the lower end of the intermediate cylinder wall 47 is made small, the amount of the powder-containing air Q leaking from the inside of the guide cylinder 3 to the outside is maximized. Can be reduced. Also, from the intake port 26,
The powder mixed air Q mixed with the outside air and generated in the bag may be sucked in a small amount, but the powder mixed air Q 2 sucked from the intake port 26 is the powder scattering prevention device 2 side. Is sucked into the air / powder separator 22 and the powder components are separated and deposited there.
