It includes a horizontal slider section 220 that moves the powder supplied from the vertical slider section 210 in a horizontal direction.

[0035] In this embodiment, the slider section 200 moves the powder using gas. In this embodiment, the gas is air, but it may be a gas other than air, such as nitrogen.

[0036] The vertical slider section 210 has a circular shape when viewed in the xy plane, and is conical (funnel-shaped) with a narrower lower end (negative z-axis direction).

[0037] The powder inside the vertical slider section 210 is supplied to the horizontal slider section 220, which is located below the vertical slider section 210.

[0038] The powder supplied to the horizontal slider section 220 is conveyed by gas to the negative x-axis direction and supplied to the powder filling section 300.

[0039] In this embodiment, the powder is conveyed by an air slider, but a general screw type may also be used.

[0040] As shown in Figures 6 to 9, the powder filling unit 300 includes a blowing unit 310 that fills the powder into the packaging bag 20 together with gas, A gas supply unit 320 that supplies gas to the blowing unit 310, A gas exhaust unit 330 that draws in air and exhausts the gas inside the packaging bag 20, The device includes a clog prevention section 340 that discharges gas to prevent powder from clogging the gas exhaust section 330.

[0041] Furthermore, the powder filling section 300 includes an insertion member 301 that is inserted into the opening 21 of the packaging bag 20, and a mounting surface 302 on which the dust collection section 400 is positioned.

[0042] The powder filling unit 300 inserts its tip end (negative x-axis direction side) into the opening 21 of the packaging bag 20 and fills the packaging bag 20 with powder.

[0043] The blowing section 310 is a through-hole provided on the tip side of the powder filling section 300, through which the powder and gas supplied from the horizontal slider section 220 pass, and the powder is filled into the packaging bag 20 by passing through the opening 21 of the packaging bag 20 from the blowing tip section 311.

[0044] The gas supply unit 320 has a supply tip 321, and in this embodiment, impact air is discharged from the supply tip 321 to the blowing unit 310.

[0045] This blows away any remaining powder inside the pipe of the blowing section 310, preventing powder from accumulating inside the blowing section 310.

[0046] The gas exhaust unit 330 has an intake tip 331 and an intake base 332. It draws in air from the intake tip 331 to draw in the gas inside the packaging bag 20 and forcibly exhausts the gas inside the packaging bag 20.

[0047] The intake tip 331 may be provided in multiple locations, and in this embodiment, four locations (331a, 331b, 331c, 331d) are provided above the blowing tip 311.

[0048] In this embodiment, intake base end portion 332 is provided on the base end side of the powder filling portion 300 in accordance with the number of intake tip portions 331.

[0049] Specifically, in this embodiment, the intake tip portion 331 is provided in four locations (331a, 331b, 331c, 331d), and the intake base portion 332 is provided in four corresponding locations (332a, 332b, 332c, 332d).

[0050] The anti-clogging section 340 is where gas is discharged to the gas exhaust section 330 to prevent the powder from clogging the gas exhaust section 330 when the gas exhaust section 330 draws in gas from inside the packaging bag 20.

[0051] Specifically, as shown in Figure 9, the gas in the blockage prevention section 340 makes a U-turn at the tip of the insertion member 301 and is discharged into the gas exhaust section 330 in the same direction as the gas that the gas exhaust section 330 draws in.

[0052] If there are multiple intake tip sections 331, it is preferable that the same number of blockage prevention sections 340 be provided.

[0053] Specifically, in this embodiment, the intake tip portion 331 is provided in four locations (331a, 331b, 331c, 331d), the intake base portion 332 is provided in four corresponding locations (332a, 332b, 332c, 332d), and the corresponding blockage prevention portion 340 is also provided in four locations (340a, 340b, 340c, 340d).

[0054] As shown in Figures 1 to 5, when the insertion member 301 of the powder filling unit 300 is inserted into the packaging bag 20, the dust collection unit 400 moves along with the movement of the insertion member 301 of the powder filling unit 300 at the opening 21 of the packaging bag 20.

[0055] The dust collection section 400 is positioned around the insertion member 301 of the powder filling section 300 and has a dust collection port 410 that can come into contact with the opening 21 of the packaging bag 20, A cylinder 420 for the dust collection port 410 to move laterally (in the x-axis direction), The system includes a dust collection pipeline 430, which is a passage for the powder collected from the dust collection port 410.

[0056] The dust collection port 410 is roughly ring-shaped in yz-plane view, has thickness in the x-axis direction, and collects powder from the inner ring side.

[0057] The dust collection port 410 is movable along the insertion member 301, and when the insertion member 301 is inserted into the packaging bag 20, the dust collection port 410 moves toward the base end side of the insertion member 301, which is in the positive x-axis direction.

[0058] When the insertion member 301 is removed from the packaging bag 20, the dust collection port 410 moves in the negative x-axis direction, which is the tip side of the insertion member 301, following the opening 21 of the packaging bag 20.

[0059] The dust collection port 410 has a surface 411 that can come into contact with the opening 21 of the packaging bag 20, The back surface 412, which is positioned on the mounting surface 302 side of the powder filling section 300, It comprises a side surface 413 positioned between the front surface 411 and the back surface 412.

[0060] In other words, the dust collection port 410 has an opening on its inner side surface (inner circumferential surface) between the ring-shaped surface 411 and the back surface 412, and powder is collected through this opening.

[0061] The surface 411 of the dust collection port 410 is ring-shaped in yz-plane view, and the radius of the inner circle 411a is wider than the width of the insertion member 301 in yz-plane view, and narrower than the width of the opening 21 of the packaging bag 20.

[0062] When the packaging bag 20 is removed from the insertion member 301, the dust collection port 410 moves along with the opening 21 of the packaging bag 20 in the negative x-axis direction. As a result, the dust collection port 410 sucks in (collects) powder adhering to the insertion member 301, powder leaking from the opening 21, and powder leaking from the blowing port 310 after the powder has been filled into the packaging bag 20.

[0063] By sucking up powder and gas at the dust collection port 410, the opening 21 of the packaging bag 20 is tightly sealed against the dust collection port 410, making it difficult for powder to leak from the opening 21.

[0064] A brush may be provided inside the dust collection port 410. This allows for the removal of powder adhering to the inside of the dust collection port 410.

[0065] In this embodiment, cylinder 420 is an electric cylinder that moves the dust collection unit 400 (movement in the x-axis direction).

[0066] Specifically, as the cylinder 420 moves, a portion of the dust collection port 410 and the dust collection pipeline 430 move in the x-axis direction.

[0067] Although a detailed description of cylinder 420 is omitted as it is a known component, cylinder 420 includes a motor 421 and a rod 422. Cylinder 420 is connected to a control unit (not shown) of the powder bagging machine 10, and the movement of cylinder 420 is controlled.

[0068] Therefore, the position of the dust collection port 410 can be adjusted, and the position of the dust collection port 410 can be aligned with the position of the opening 21 of the packaging bag 20.

[0069] Specifically, as the rod 422 of the cylinder 420 moves to the negative x-axis side, the dust collection port 410 also moves to the negative x-axis side.

[0070] When the dust collection port 410 moves to the negative x-axis direction, the dust collection pipeline 430 extends.

[0071] The dust collection pipeline 430 is connected to the dust collection port 410, and the powder sucked into the dust collection port 410 passes through the dust collection pipeline 430 and is collected.

[0072] The dust collection pipeline 430 is retractable and extends in accordance with the movement of the rod 422 of the cylinder 420.

[0073] The present invention can also be implemented in various improved, modified, or altered forms without departing from its spirit. [Explanation of Symbols]
