Description

Technical Field

[0001] The present invention relates to a powder bagging machine for filling powder into a packaging bag.

Background Art

[0002] Filling powder such as flour, powdered feed, and mineral powder into a packaging bag by a powder bagging machine is performed by holding the packaging bag in a vertical state and inserting a supply pipe into the valve opening of the packaging bag.

[0003] When the powder is filled into the packaging bag through the valve opening by this powder bagging machine, the powder-filled packaging bag is conveyed to the sealing position with the valve opening unsealed, and after the valve opening is sealed by the sealing device, it is discharged from the sealing device.

[0004] In this type of conventional sealing device, a powder-filled packaging bag is received from the powder bagging machine, the unsealed filled packaging bag is toppled from the vertical state and laid flat on a roller-type or belt-type conveyor, and the filled packaging bag is conveyed to the sealing position by this conveyor.

[0005] During this conveyance, the filled packaging bag laid flat on the conveyor with the upper and lower sides (the short sides of the bag) along the conveyance direction is tilted at an appropriate angle with respect to the direction orthogonal to the conveyance direction in plan view by a bag posture tilting mechanism.

[0006] Then, the flat-filled packaging bag sent out from the bag posture tilting mechanism is sandwiched between a roller conveyor (or a belt conveyor) and a press conveyor and pressed from above, so that the filled packaging bag is flattened and the thickness is shaped to a specified dimension, and then the valve opening of the filled packaging bag is sealed by a sealing mechanism.

[0007] The sealing mechanism is composed of a heater unit and a cooler unit. The heater unit heats and melts the adhesive applied and dried on the inner surface of the valve opening to join the inner surfaces of the valve opening, and the cooler unit cools and fixes the adhesive to seal the valve opening.

[0008] Patent Document 1 discloses a resin raw material supply hopper that can safely and reliably eliminate bridging of the resin raw material near the discharge port of the hopper, in which resin raw material is supplied to an extrusion molding machine.

[0009] Specifically, Patent Document 1 discloses a resin raw material supply hopper comprising a funnel-shaped portion that is inclined to gradually decrease toward an outlet formed in the center, and a cylindrical portion extending vertically provided at the upper end of the funnel-shaped portion, wherein the resin raw material accumulated inside is discharged from the outlet, and an air nozzle is installed as a blowing means on at least the opposing walls of the funnel-shaped portion.

[0010] [Patent Document 1] Japanese Patent Publication No. 2000-43983 [Overview of the Initiative] [Problems that the invention aims to solve]

[0011] Depending on the type of powder, some powders are prone to bridging or other issues, or they tend to adhere to machinery and have poor fluidity, making it difficult to transport the powder.

[0012] Furthermore, some powders do not transport smoothly with agitators or screws, making it difficult to bag them.

[0013] The objective of this invention is to enable smooth transport of powder within the machine. [Means for solving the problem]

It includes a powder filling section located to the side of the horizontal slider section, which conveys powder from the horizontal slider section and fills the packaging bag with the powder, The aforementioned vertical slider portion comprises a funnel-shaped vertical slider member that has high self-lubricating properties and is capable of passing gas through, A central gas supply unit that injects gas downwards into the center of the funnel-shaped vertical slider member in a plan view, A first gas supply unit that injects gas into the vertical slider portion above the vertical slider member, It comprises a second gas supply unit that supplies gas from the outside of the vertical slider member to the inside of the vertical slider member, The horizontal slider portion comprises a cylindrical horizontal slider member that has high self-lubricating properties and is capable of passing gas through it, This powder bagging machine includes a horizontal gas supply unit that injects gas into the cylindrical horizontal slider member.

[0015] With this type of device, powder can be sprayed, and even powders with poor fluidity are less likely to adhere to the inside of the machine, allowing the powder to be smoothly transported by air or other gases.

[0016] Note that "vertical" here simply means that the powder can be conveyed downwards; it does not need to be perfectly vertical.

[0017] Similarly, "horizontal" simply means that the powder can be transported horizontally; it does not need to be perfectly horizontal.

[0018] Examples of vertical and horizontal slider members include ultra-high molecular weight polyethylene. The vertical and horizontal slider members may also be made of resin or sintered metal.

[0019] The powder bagging machine according to the second aspect of the present invention is the powder bagging machine according to the first aspect, wherein the horizontal slider portion includes a third gas supply portion that supplies gas from the outside of the horizontal slider member to the inside of the horizontal slider member. The powder bagging machine according to claim 1.

[0020] In such a case, inside the horizontal slider member, powder can be made to flow in a jet stream. Even for powders with poor fluidity, it is difficult for the powder to adhere inside the machine, and the powder can be smoothly conveyed by a gas such as air.

[0021] The powder bagging machine according to the second aspect of the present invention is the powder bagging machine according to the first aspect, wherein the central gas supply portion includes a horizontal gas passage portion that extends horizontally inside the vertical slider portion, a vertical gas passage portion that injects the gas supplied from the horizontal gas passage portion downward, and an umbrella portion that covers the lower end side in the downward direction of the vertical gas passage portion. The powder bagging machine is provided with.

[0022] In such a case, powder can be made to flow in a jet stream, and it becomes difficult for the powder to clog when being conveyed from the vertical slider portion to the horizontal slider portion.

[0023] Note that "horizontal" means that the gas can be moved in the lateral direction, and it is not necessary to be exactly horizontal.

[0024] Similarly, here "vertical" means that the gas can be moved downward, and it is not necessary to be exactly vertical.

[0025] The powder bagging machine according to the third aspect of the present invention is the powder bagging machine according to the first aspect, wherein the horizontal gas supply portion injects gas in the extending direction of the cylindrical horizontal slider member, the third gas supply portion includes a third lower gas supply portion that is disposed on the bottom surface which is the lower side of the horizontal slider portion and supplies gas, and a third lateral gas supply portion that is disposed on the side surface of the horizontal slider portion and supplies gas. The powder bagging machine is provided with.

[0026] With this type of device, powder can be sprayed, and when transporting powder from a vertical to a horizontal direction, the powder is less likely to adhere to the horizontal slider section, allowing for smooth powder transport.

[0027] A powder bagging machine according to the fourth aspect of the present invention is a powder bagging machine according to the first aspect, wherein the vertical slider section is composed of an upper slider section and a lower slider section. The first gas supply unit is located above the slider, The second gas supply unit is located below the slider, The vertical slider member is provided on the inside of the lower part of the slider. This is a powder bagging machine in which compressed gas is injected from the first gas supply unit.

[0028] With this design, powder can be jetted, and the compressed gas makes it difficult for the powder to adhere to the vertical slider section. Furthermore, by providing a vertical slider component made of ultra-high molecular weight polyethylene or similar material on the lower side where powder is more likely to adhere, the powder can be easily transported.

[0029] A powder bagging machine according to a fifth aspect of the present invention is a powder bagging machine according to a first aspect, wherein the first gas supply unit is located on the upper side and the gas is injected into the interior of the vertical slider unit, The powder bagging machine comprises a first lower gas supply unit located below the first upper gas supply unit and at a position different from the lateral position of the first upper gas supply unit, from which gas is injected into the interior of the vertical slider unit.

[0030] By positioning the gas supply unit at different height and lateral locations, the powder can be jetted, making it easier to transport the powder within the vertical slider section.

[0031] A powder bagging machine according to the sixth aspect of the present invention is a powder bagging machine according to the fourth aspect, wherein the inner surface of the upper part of the slider is polygonal in plan view, This is a powder bagging machine in which the supply port of the first gas supply unit is planar.

[0032] In this configuration, even powders with poor fluidity are less likely to adhere to the inside of the machine, and the powder can be smoothly transported by gases such as air. [Brief explanation of the drawing]

[0034] The powder bagging machine 10 according to this embodiment will be described with reference to the drawings.

[0035] <First Embodiment> As shown in Figures 1 to 8, the powder bagging machine 10 according to this embodiment includes a hopper section 100 that supplies powder into the powder bagging machine 10, A slider section 200 is located at the bottom of the hopper section 100 and transports the powder by gas, A powder filling unit 300 is a feeder that fills the powder into the packaging bag 20, The system includes a dust collection unit 400 positioned around the blowing pipe 310 of the powder filling unit 300.

[0036] The hopper section 100 includes a hopper body section 110 for supplying powder, The hopper body 110 includes a stirring section (not shown) located at the bottom (negative z-axis direction).

[0037] In this embodiment, the hopper body 110 is circular in shape in an xy-plane view, and the powder supplied from the top flows downwards.

[0038] The lower part (negative z-axis direction side) of the hopper body 110 is connected to the slider 200, and the powder inside the hopper body 110 is supplied to the slider 200.

[0039] The hopper body 110 is provided with a window 111 that allows the operator to see inside, enabling them to check the state of the powder inside the hopper body 110.

[0040] Furthermore, a cover portion 112 is provided above the window portion 111 (on the positive z-axis side) to prevent the gas supplied to the interior from escaping from above.

[0041] The slider section 200 is connected to the hopper body section 110 and is a vertical slider section 210 that conveys the powder supplied from inside the hopper body section 110 in a vertical direction. A central gas supply unit 220 is located within the vertical slider unit 210, It includes a horizontal slider section 230 that conveys the powder supplied from the vertical slider section 210 in a horizontal direction.

[0042] In this embodiment, the slider section 200 transports the powder using gas. While the gas in this embodiment is air, it may be a gas other than air, such as nitrogen. The gas also jets the powder within the slider section 200.

[0043] Furthermore, "vertical" in this context simply means that the powder can be transported downwards; it does not need to be perfectly vertical.

[0044] Similarly, "horizontal" simply means that the powder can be transported horizontally; it does not need to be perfectly horizontal.

[0045] In this embodiment, the vertical slider portion 210 has a circular shape in xy-plane view and is conical (funnel-shaped) with a narrower lower end (negative z-axis direction).

[0046] The vertical slider section 210 includes an upper slider section 201 positioned above it, A lower slider portion 202 is connected to and positioned below the upper slider portion 201, The system includes a vertical slider member 203 positioned inside the lower part 202 of the slider.

[0047] In this embodiment, the vertical slider member 203 is positioned downwards where powder is likely to adhere, and is made of funnel-shaped ultra-high molecular weight polyethylene (UHMWPE).

[0048] Ultra-high molecular weight polyethylene (UHMWPE) offers excellent self-lubricating properties, wear resistance, chemical resistance, and impact resistance, and can be processed to allow gas to pass through.

[0049] The vertical slider member 203 may be self-lubricating and allow gas to pass through, and may be made of a resin other than ultra-high molecular weight polyethylene, or it may be made of sintered metal.

[0050] The upper part 201 of the slider includes a first upper gas supply unit 211, which is positioned on the upper side and is a first gas supply unit that injects gas into the interior (inside) of the vertical slider unit 210, The system is equipped with a first lower gas supply unit 212, which is a first gas supply unit located below the first upper gas supply unit 211, and into which gas is injected into the interior (inside) of the vertical slider unit 210.

[0051] In this embodiment, the gas supplied by the first upper gas supply unit 211 and the first lower gas supply unit 212 is compressed air, but it may be a gas other than air, such as nitrogen.

[0052] The gas injected from the first upper gas supply unit 211 and the first lower gas supply unit 212 spreads out in a ripple-like pattern along the shape of the upper part 201 of the slider.

[0053] In this embodiment, the first upper gas supply unit 211 is provided in four locations (211a, 211b, 211c, 211d) on the same xy plane view, and is arranged symmetrically (at positions where the central angle with respect to the center of the vertical slider unit 210 as the origin in the xy plane view is 90°).

[0054] The first lower gas supply unit 212 is located below the first upper gas supply unit 211, and in this embodiment, there are four units (212a, 212b, 212c, 212d) located midway between each of the first upper gas supply units 211 in an xy-plane view.

[0055] In other words, the first lower gas supply unit 212 is positioned at a different location laterally from the first upper gas supply unit 211.

[0056] In this embodiment, impact air (compressed air) is injected into the vertical slider section 210 by the first upper gas supply section 211 and the first lower gas supply section 212. The first upper gas supply section 211 and the first lower gas supply section 212 may use pulsed air.

[0057] The first upper gas supply unit 211 is positioned in a balanced manner, and the first lower gas supply unit 212, located below it, is positioned in an xy plane view where the first upper gas supply unit 211 is not located, which has the effect of making it difficult for powder to adhere to the surface.

[0058] Between the upper part 201 and the lower part 202 of the slider, a central gas supply unit 220 is positioned, extending in the y-axis direction within the vertical slider 210. Specific details will be described later.

[0059] The lower part of the slider 202 includes a second gas supply unit 213, which is a gas supply unit that supplies gas to the inside of the vertical slider unit 210, The lower part of the slider 202 is positioned inside (radially inward in the xy plane view), and includes a vertical slider member 203 through which the gas supplied by the second gas supply unit 213 passes.

[0060] In this embodiment, the second gas supply unit 213 is arranged in four locations (213a, 213b, 213c, 213d) in the xy plane at the same central angle as the first upper gas supply unit 211 in the xy plane.

[0061] The vertical slider member 203 is positioned inside the lower part 202 of the slider and has a similar funnel shape.

[0062] The gas supplied from the second gas supply unit 213 passes through the vertical slider member 203, which is located inside the lower part of the slider 202, and is supplied to the inside of the vertical slider member 203.

[0063] The vertical slider member 203 is porous, allowing the gas to pass through it and cause the powder to be ejected. This makes it difficult for the powder to adhere to the vertical slider member 203, and makes the powder flow more easily.

[0064] Therefore, the powder adhering to the vertical slider member 203 is also more easily flowed downward by the jetting action.

[0065] The vertical slider section 210 comprises an upper slider section 201, a lower slider section 202, and a vertical slider member 203. The vertical slider member 203 is made of funnel-shaped ultra-high molecular weight polyethylene. The vertical slider section 210 includes a first upper gas supply section 211, a first lower gas supply section 212, and a second gas supply section 213.

[0066] The central gas supply unit 220 includes a horizontal gas passage section 221 that extends laterally (in the y-axis direction) within the vertical slider section 210, A vertical gas passage section 222 injects the gas supplied from the horizontal gas passage section 221 downwards (negative z-axis direction), The device includes an umbrella-shaped portion 223 that covers the tip side (negative z-axis direction side) of the vertical gas passage portion 222.

[0067] Note that "horizontal" here simply means that the gas can be moved horizontally; it does not need to be perfectly horizontal.

[0068] Similarly, "vertical" here simply means that the gas can be moved downwards; it does not need to be perfectly vertical.

[0069] The horizontal gas passage section 221 extends in the y-axis direction within the vertical slider section 210, and the vertical gas passage section 222 is attached to its central portion (the center of the vertical slider section 210 in an xy-plane view).

[0070] The central parts of the horizontal gas passage section 221 and the vertical gas passage section 222 are pipe-shaped through holes, and the gas that passes through the horizontal gas passage section 221 moves through the central part of the vertical gas passage section 222 to the gas passage tip section 222a.

[0071] The horizontal gas passage section 221 is positioned to pass through the center of the circular vertical slider section 210 in an xy-plane view.

[0072] In other words, the horizontal gas passage section 221 is positioned to pass over the through-hole for transporting powder from the vertical slider section 210 to the horizontal slider section 230.

[0073] A vertical gas passage section 222 is attached to the central part of the horizontal gas passage section 221 in an xy-plane view.

[0074] In other words, the vertical gas passage section 222 is positioned above the through-hole for transporting powder from the vertical slider section 210 to the horizontal slider section 230.

[0075] The vertical gas passage section 222 injects the gas supplied from the horizontal gas passage section 221 downwards.

[0076] The gas passage tip 222a, which is the tip of the vertical gas passage section 222, is located on the lower side (negative z-axis side) of the vertical gas passage section 222, and gas is injected from there.

[0077] In this embodiment, impact air or pulsed air is injected from the tip portion 222a of the gas passage.

[0078] As gas is ejected from the gas passage tip 222a, the powder is jetted, reducing powder adhesion below the vertical slider section 210, and enabling smooth transport of the powder from the vertical slider section 210 to the horizontal slider section 230.

[0079] The umbrella portion 223 has a conical shape that covers the upper part of the gas passage tip portion 222a and is open at the bottom.

[0080] The umbrella portion 223 prevents the powder from adhering to the upper part of the gas passage tip portion 222a, making it easier for the powder to flow.

[0081] The powder inside the vertical slider section 210 is transported to the horizontal slider section 230 located below the vertical slider section 210.

[0082] The powder conveyed to the horizontal slider section 230 is transported by gas to the negative x-axis direction and then to the powder filling section 300.

[0083] The horizontal slider section 230 is positioned on the side facing the positive x-axis and includes a horizontal gas supply section 231 that injects gas toward the negative x-axis direction, The third lower gas supply unit 232 is located on the bottom surface of the horizontal slider unit 230, which is on the negative z-axis side, and supplies gas. The device includes a third lateral gas supply unit 233, which is a third gas supply unit that is positioned on the side surface (bottom or top surface) of the horizontal slider unit 230 on the y-axis side or the z-axis side, and supplies gas.

[0084] Furthermore, in this embodiment, the horizontal slider section 230 is provided with a horizontal slider member 204 made of ultra-high molecular weight polyethylene (UHMWPE) to facilitate the flow of powder inside.

[0085] By using ultra-high molecular weight polyethylene (UHMWPE) as the horizontal slider member 204, powder is less likely to adhere to the horizontal slider member 204, and processing makes it porous, preventing powder from passing through while allowing gas to pass through.

[0086] The horizontal slider member 204 may be self-lubricating and allow gas to pass through, and may be made of a resin other than ultra-high molecular weight polyethylene, or it may be made of sintered metal.

[0087] In this embodiment, the horizontal slider member 204 is cylindrical, tapering towards the tip (negative x-axis direction), and is porous.

[0088] The horizontal slider member 204 is connected to the vertical slider member 203 by a connecting member 205, and the powder inside the vertical slider member 203 is transported into the horizontal slider member 204 located below it.

[0089] Furthermore, as the gas passes through the horizontal slider member 204, the powder is jetted, improving the fluidity of the powder.

[0090] The horizontal gas supply unit 231 injects gas in the extension direction (x-axis direction) of the cylindrical horizontal slider member 204, causing the powder to jet and improving the fluidity of the powder.

[0091] In this embodiment, pulsed air or impact air (compressed air) is injected from the horizontal gas supply unit 231.

[0092] The third lower gas supply unit 232 allows the supplied gas to pass through the horizontal slider member 204 and injects the gas towards the powder inside the horizontal slider member 204, causing the powder to jet and improving the fluidity of the powder.

[0093] The third horizontal gas supply unit 233 supplies the supplied gas through the horizontal slider member 204, into the horizontal slider section 230, and supplies the gas towards the powder inside the horizontal slider member 204.

[0094] This causes the powder inside the horizontal slider section 230 to be ejected, improving the fluidity of the powder.

[0095] In this embodiment, the third horizontal gas supply unit 233 is located in the horizontal slider unit 230 and is provided in three locations (233a, 233b, 233c).

[0096] 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.

[0097] 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.

[0098] The dust collection unit 400 sucks in the gas inside the packaging bag 20 and sucks in the dust that leaks out from the opening 21 of the packaging bag 20.

[0099] <Second Embodiment> In the first embodiment, the configuration used a first upper gas supply unit 211 and a first lower gas supply unit 212 as the first gas supply unit, but in the second embodiment, a fourth gas supply unit 240 is used as the first gas supply unit.

[0100] In the second embodiment, the same numbering is used for components similar to those in the first embodiment, and their explanations are omitted or simplified.

[0101] As shown in Figures 9 to 11, in the second embodiment, the upper slider portion 201 of the vertical slider portion 210 is polygonal, and the gas is supplied by a surface. Note that Figure 9, a cross-sectional view of BB, is a cross-sectional view of the state in which the vertical slider member 203 is not in place.

[0102] In this embodiment, the inner surface of the upper part 201 of the slider is hexagonal in an xy-plane view, and the fourth gas supply unit 240, which is a gas supply unit, is arranged on the upper part 201 of the slider.

[0103] In this embodiment, the inner surface of the upper part 201 of the slider is hexagonal in an xy-plane view, but it may also be a quadrilateral, octagon, or any other polygon.

[0104] In this embodiment, the fourth gas supply unit 240 is arranged in six locations (241, 242, 243, 244, 245, 246), and the gas supply port is planar.

[0105] Specifically, the fourth gas supply unit 240, like the vertical slider member 203 and the horizontal slider member 204, is made of a self-lubricating and gas-passable material, and in this embodiment, it is made of ultra-high molecular weight polyethylene (UHMWPE).

[0106] The fourth gas supply unit 240 may be made of resin or sintered metal, similar to the vertical slider member 203 and the horizontal slider member 204.

[0107] In the fourth gas supply unit 240, the gas is passed through a material such as ultra-high molecular weight polyethylene, which causes the powder to be jetted and makes it easier for the powder to flow effectively.

[0108] With this structure, gas can be supplied to the interior of the upper part 201 of the slider over a wide surface area, improving the fluidity of the powder.

[0109] The present invention can also be implemented in various improved, modified, or altered forms without departing from its spirit. [Explanation of Symbols]
