Further, other materials may be used.

  The hopper 2 is a container (container) that contains a powder material therein. For example, as shown in FIGS. 1 and 4, the hopper 2 can have a shape that is long in the horizontal direction (horizontal shape). Moreover, as shown in FIG. 2, the hopper 2 can be made into the shape which becomes narrow as it progresses below.

  Here, the powder material is powdery or granular, for example, curry powder, stew powder, green juice powder, milk tea powder, cocoa powder, coffee powder, potato starch, powdered milk and the like. The powder material is also referred to as a filling material, a powder raw material, and a filling raw material.

  Also, as shown in FIG. 4, holes (powder material input ports) 23a to 23j for supplying powder material to the sub hoppers 3a to 3j are provided on the bottom surface of the hopper 2 at predetermined intervals. Further, convex portions 19 a to 19 i are provided on the bottom surface of the hopper 2. That is, on the bottom surface of the hopper 2, the holes (powder material input ports) 23a to 23j and the convex portions 19a to 19i are alternately arranged in one row.

  As shown in FIG. 4, the powder material accommodated in the hopper 2 is stirred by the first coil screw 10 and the second coil screw 11. In the stirring by the first coil screw 10 and the second coil screw 11, the entire powder material accommodated in the hopper 2 is stirred so as to flow in one direction on a horizontal plane.

  For example, when rotating the first coil screw 10 and the second coil screw 11 in the directions of arrows 31 and 32 shown in FIG. 2, the powder material accommodated in the hopper 2 is changed to the arrow 33 shown in FIG. Stir to flow in the direction.

  Moreover, the powder material accommodated in the hopper 2 is stirred by the stirring rods 6a to 6j. In the stirring by the stirring rods 6a to 6j, the powder material accommodated in the hopper 2 is stirred so as to be conveyed downward in the vertical direction.

  Thus, the hopper 2 is provided with a plurality of holes (powder material input ports) 23a to 23j for supplying the powder material to the sub hoppers 3a to 3j on the inner bottom surface, and between the adjacent holes. Protrusions 19a to 19i are provided.

  The sub hoppers 3a to 3j accommodate powder materials supplied from holes (powder material input ports) 23a to 23j (shown in FIG. 4) on the bottom surface of the hopper 2 and supply them to the filling pipes 4a to 4j (containers) It is. The sub hoppers 3a to 3j are provided with auger screws 5a to 5j and stirring rods 6a to 6j in the hollow portion.

  The upper ends of the sub hoppers 3a to 3j are attached to holes (powder material input ports) 23a to 23j on the bottom surface of the hopper 2. Then, as shown in FIGS. 5 to 7, the inside of the sub hoppers 3 a to 3 j and the inside of the hopper 2 are connected. For example, the sub hoppers 3a to 3j and the hopper 2 are attached by attachment members (not shown) such as screws.

  For example, as shown in FIG. 8, in the sub hopper 3b, the upper opening 35b can have a substantially rectangular shape, and the lower opening 36b can have a substantially circular shape. Further, as shown in FIGS. 6 to 8, the inner surface 37b of the sub hopper 3b can be made to become narrower as it goes downward and from a substantially rectangular shape to a substantially circular shape as it goes downward. . The same applies to the other sub hoppers 3a, 3c to 3j.

  In this manner, the sub hoppers 3a to 3j are detachably suspended from the lower end portion of the hopper 2, and supply the powder material supplied from the hopper 2 to the filling pipes 4a to 4j suspended from the lower end portion. Further, the sub hoppers 3a to 3j are vertically arranged in the horizontal direction at the lower end portion of the hopper 2. The sub hoppers 3a to 3j have a shape in which the inner shape becomes narrower downward.

  The filling pipes 4a to 4j are substantially cylindrical pipes that discharge the powder material supplied from the sub hoppers 3a to 3j from the discharge port at the lower end. In addition, as shown in FIGS. 1 and 5, the filling pipes 4 a to 4 j are provided with auger screws 5 a to 5 j in the hollow portion. The upper ends of the filling pipes 4a to 4j are attached to the lower ends of the sub hoppers 3a to 3j, and the insides of the filling pipes 4a to 4j are connected to the insides of the sub hoppers 3a to 3j. For example, the filling pipes 4a to 4j and the sub hoppers 3a to 3j are attached by attachment members (not shown) such as screws. The filling pipes 4a to 4j are also referred to as auger tubes.

  In this way, the filling pipes 4a to 4j are detachably suspended at the upper ends of the sub hoppers 3a to 3j, and discharge the powder material supplied from the sub hoppers 3a to 3j from the discharge port at the lower end. .

  The auger screws 5a to 5j are screws having substantially spiral blades. In addition, in FIG. 5, the substantially helical blade | wing 22b of the auger screw 5b is shown. The auger screws 5a to 5j are rotatably inserted into the hollow portions of the sub hoppers 3a to 3j and the filling pipes 4a to 4j, and are arranged on the same axis as the sub hoppers 3a to 3j and the filling pipes 4a to 4j.

  Here, of the substantially spiral blade 22b in the auger screw 5b, the upper part (the part corresponding to h2 shown in FIG. 5) is installed inside the sub hopper 3b. Further, the lower part (the part corresponding to h1 shown in FIG. 5) of the substantially spiral blade 22b is installed inside the filling pipe 4b.

  For example, when the upper part of the auger screw 5b (the part corresponding to h2 shown in FIG. 5) rotates, the powder material accommodated in the sub hopper 3b is supplied to the upper end of the filling pipe 4b. Further, when the lower portion of the auger screw 5b (the portion corresponding to h1 shown in FIG. 5) rotates, the powder material supplied from the sub hopper 3b is conveyed downward through the filling pipe 4b, and the filling pipe It is discharged from the outlet at the lower end of 4b.

  The convex portions 19 a to 19 i are mountain-shaped convex portions installed between the inlets of the sub hoppers 3 a to 3 j on the bottom surface of the hopper 2. By installing the convex portions 19a to 19i between the inlets of the sub hoppers 3a to 3j, the movement of the powder material conveyed to the sub hoppers 3a to 3j in the vicinity of the bottom surface of the hopper 2 can be suppressed. it can. In addition, about the convex parts 19a thru | or 19i, you may make it set it as the other shape (for example, plate shape) which can suppress the movement to the horizontal direction of powder material.

  The stirring rods 6a to 6j are for stirring the powder material accommodated in the hopper 2 and the sub hoppers 3a to 3j by rotating inside the hopper 2 and the sub hoppers 3a to 3j.

  The auger motors 7a to 7j are connected to the auger screws 5a to 5j via the rotation shafts 21a to 21j, and are drive mechanisms (drive units) that rotate the auger screws 5a to 5j. For example, as shown in FIG. 5, the upper end of the auger screw 5b is fitted into the mounting hole 25b provided at the lower end of the rotating shaft 21b, and the mounting hole provided at the lower end of the rotating shaft 21b. An attachment member is inserted into 26b and an attachment hole 24b provided in the upper end portion of the auger screw 5b. Thereby, the rotating shaft 21b and the auger screw 5b are connected.

  Further, the auger motors 7a to 7j rotate the auger screws 5a to 5j installed in the sub hoppers 3a to 3j and the filling pipes 4a to 4j, so that the insides of the sub hoppers 3a to 3j and the filling pipes 4a to 4j are rotated. The powder material is conveyed to the lower side. Note that. In the embodiment of the present invention, an example in which one auger screw is rotated by one auger motor is shown, but a plurality of auger screws may be rotated by one auger motor.

  The stirring motor 8 is connected to the stirring rods 6a to 6j via the drive transmission members 20, 20a to 20j, and is a drive mechanism (driving unit) that rotates the stirring rods 6a to 6j. Further, the stirring rods 6a to 6j installed in the hopper 2 and the sub hoppers 3a to 3j are rotated by the stirring motor 8, so that the powder material accommodated in the hopper 2 and the sub hoppers 3a to 3j Stir. For example, a pulley or the like can be used as the drive transmission members 20, 20a to 20j.

  The 1st coil screw 10 and the 2nd coil screw 11 agitate and equalize the powder material stored in the inside of the hopper 2 by rotating the inside of the hopper 2. Moreover, as shown in FIG. 4, the 1st coil screw 10 and the 2nd coil screw 11 attach the substantially coil-shaped stirring member to the rod-shaped main-body part. In addition, instead of the substantially coil-shaped stirring member, other shapes of stirring members (for example, substantially spiral blades) may be attached to the main body portions of the first coil screw 10 and the second coil screw 11. Good.

  In this way, the first coil screw 10 and the second coil screw 11 are arranged in a substantially horizontal plane inside the hopper 2 so as to be arranged in parallel and rotatably installed, and a rod-shaped first stirring member and a rod-shaped second stirring member. It is.

  The coil screw motor 12 is connected to the second coil screw 11 and is a drive mechanism (drive unit) that rotates the first coil screw 10 and the second coil screw 11.

  The inter-coil screw drive transmission unit 13 transmits the drive of the second coil screw 11 connected to the coil screw motor 12 and rotated to the first coil screw 10. For example, the inter-coil screw drive transmission unit 13 transmits the drive of the second coil screw 11 to the first coil screw 10 so as to be in the direction opposite to the rotation direction of the coil screw motor 12. For example, when the rotation direction of the coil screw motor 12 is the direction of the arrow 31 shown in FIG. 2, the inter-coil screw drive transmission unit 13 has the direction of the rotation of the first coil screw 10 as shown by the direction of the arrow 32 shown in FIG. Thus, the drive of the second coil screw 11 is transmitted to the first coil screw 10.

  As described above, the coil screw motor 12 and the inter-coil drive transmission unit 13 have a direction in which the powder material flows by the rotation of the first coil screw 10 and a direction in which the powder material flows by the rotation of the second coil screw 11. This is a drive unit that rotationally drives the first coil screw 10 and the second coil screw 11 so as to be opposite in the axial direction of the first coil screw 10 and the second coil screw 11.

  The upper and lower columns 14 a and 14 b are columns that are installed on the base 15 and support the base 16. As shown in FIGS. 1 and 9, the upper and lower columns 14a and 14b can move the base 16 in the vertical direction. The base 15 is provided with upper and lower support columns 14a and 14b and holes 15a to 15j (shown in FIG. 9). The holes 15a to 15j are holes for fitting the filling pipes 4a to 4j.

  As described above, the upper and lower columns 14a and 14b move up and down the respective parts of the hopper 2, the sub hoppers 3a to 3j, the filling pipes 4a to 4j, the auger screws 5a to 5j, and the auger motors 7a to 7j. Let

  For example, when the operation of filling the packaging material with the powder material using the auger filling device 1 is performed, as shown in FIG. 1, the filling pipes 4a to 4a are inserted into the holes 15a to 15j (shown in FIG. 9) of the base 15. The base 16 is moved downward in the vertical direction so that 4j is inserted.

  Further, for example, when maintenance of the auger filling device 1 is performed, the base 16 is moved in the vertical direction so that the filling pipes 4a to 4j are removed from the holes 15a to 15j of the base 15 as shown in FIG. Move up.

  As described above, when the auger filling apparatus 1 is operated, the respective parts are lowered to insert the filling pipes 4a to 4j into the holes 15a to 15j, and during the maintenance of the auger filling apparatus 1, the respective parts are raised to connect the filling pipes 4a to 4j. Extract from holes 15a to 15j.

  The base 16 is provided with a stirring motor 8, a frame 17, a support frame 18, and 10 holes. These ten holes are holes for fitting the rotating shafts 21a to 21j connected to the auger motors 7a to 7j.

  In the base 16, a support frame 18 is provided in the frame 17. Further, auger motors 7 a to 7 j are attached to the support frame 18.

  Next, a case where maintenance of the auger filling apparatus 1 is performed will be described.

  For example, when changing the powder material filled in the packaging bag, it is necessary to replace the sub hoppers 3a to 3j and the filling pipes 4a to 4j. As described above, when the sub hoppers 3a to 3j and the filling pipes 4a to 4j are exchanged, as shown in FIG. 9, the upper and lower columns 14a are moved until the filling pipes 4a to 4j are separated from the holes 15a to 15j of the base 15. , 14b are moved upward.

  Then, the sub hoppers 3a to 3j (filling pipes 4a to 4j) are removed from the hopper 2. Then, the sub hoppers 3a to 3j (filling pipes 4a to 4j) corresponding to the changed powder material are attached to the hopper 2.

  Thus, in the embodiment of the present invention, the sub hoppers 3a to 3j for the auger screws 5a to 5j are attached to the lower part of the hopper 2. Further, on the bottom surface of the hopper 2, convex portions 19a to 19i are installed between the inlets of the sub hoppers 3a to 3j. Thereby, since the movement of the powder material in the horizontal direction can be suppressed around the portion where the auger screws 5a to 5j are inserted, the state in which the powder material is filled can be maintained. As described above, by maintaining the state in which the powder material is filled around the portions where the auger screws 5a to 5j are inserted, the powder material can be stably filled into the packaging bag.

  Further, it is possible to prevent the powder material from being shifted to one side in the hopper 2 as the auger screws 5a to 5j rotate in one direction, thereby preventing blocking, and the powder material is uniformly distributed to the filling pipes 4a to 4j. Can be sent to. As a result, it is possible to prevent the occurrence of powder cracking in the powder material, the generation of defective packaging products whose filling amount does not reach a fixed amount, and the generation of defective packaging products having an obstacle to powder cracking in the powder material. Can be prevented.

  Further, by making it possible to remove the sub hoppers 3a to 3j from the hopper 2, it is possible to deal with a wide variety of powder materials with a minimum of partial change. Thereby, daily maintenance can be made easy.

  Further, by performing leveling stirring (stirring by the leveling stirring unit 9) using two coil screws (first coil screw 10 and second coil screw 11), the side of the powder material inside the hopper 2 is obtained. A slippage can be prevented.

  Further, even when drop filling by mass measurement or the like is difficult due to powder rising or the like, the automatic filling and packaging machine can appropriately perform filling and packaging of the powder material. The auger filling device 1 is a multi-row auger filling device having a plurality of rows of filling functions. For this reason, productivity can be improved by using the auger filling apparatus 1. FIG.

  FIG. 8 shows an example of the inner shape of the sub hopper 3b in which the upper opening 35b has a substantially rectangular shape and the lower opening 36b has a substantially circular shape. However, the inner shapes of the sub hoppers 3a to 3j may be other shapes. Therefore, another example of the inner surface shape of the sub hoppers 3a to 3j is shown in FIG.

  FIG. 12 is a diagram showing an example of the inner surface shape of the sub hoppers 3a to 3j in the embodiment of the present invention.

  As shown in FIG. 12, in the sub hoppers 3a to 3j, both the upper opening 41b and the lower opening 42b can be formed into a substantially circular shape. Further, the inner surfaces 43b of the sub hoppers 3a to 3j can be shaped so as to become narrower as they proceed downward. For example, the shape of the inner surface 43b of the sub hoppers 3a to 3j can be a downward truncated cone shape.

  FIG. 13 is a front view showing a simplified example of the external configuration of the vertical automatic filling and packaging machine 50 according to the embodiment of the present invention.

  The vertical automatic filling and packaging machine 50 is an automatic packaging machine (vertical multi-row automatic filling and packaging machine) that forms a packaging bag by sealing a packaging film using the auger filling apparatus 1. In other words, the vertical automatic filling and packaging machine 50 is a vertical multi-row filling and packaging machine that simultaneously performs a plurality of rows of powder filling and packaging. That is, the vertical automatic filling and packaging machine 50 can simultaneously form a plurality of packaging bags by using the auger filling device 1. Since the auger filling apparatus 1 shown in FIG. 13 is substantially the same as that shown in FIGS. 1 to 11, illustration of some symbols and detailed description of each part are omitted. Moreover, in FIG. 13, a part of auger filling apparatus 1 shown in FIG. 1 thru | or FIG. 11 is changed and shown.

  As described above, the powder material is discharged from the discharge ports 50a to 50j of the filling pipes 4a to 4j.

  For example, in the vertical automatic filling and packaging machine 50, a long packaging film drawn from a packaging film roll is continuously conveyed, the long packaging film is formed into a cylindrical shape, and a bag portion (long The packaging film is formed into a bag shape).

  For example, a longitudinal heat seal is applied by sandwiching a packaging film folded in two by a former with a longitudinal sealing device. In addition, the transverse sealing device performs transverse heat sealing on the packaging film that is folded in two by the former and longitudinally heat sealed by the longitudinal sealing device to form a bag shape. That is, the packaging film folded in two has a bag shape in which the lower and side portions are sealed and the upper side is vacant (a long packaging film having a bag shape).

  Subsequently, after the powder material discharged from the discharge ports 50a to 50j of the filling pipes 4a to 4j is charged into the packaging film having a bag shape on the upper side, the horizontal heat seal is applied to the input port by the horizontal seal device. Is applied and sealed. Thereby, the upper part of the bag portion filled with the powder material is sealed, and the bag-shaped packaging film having an open upper side becomes a bag shape, and the next bag shape is formed.

  Subsequently, the packaging film sealed by the vertical sealing device and the horizontal sealing device is cut for each bag by the cutter device. Subsequently, the packaging bags cut into individual packaging forms are conveyed by a conveying unit (for example, a belt conveyor) and boxed.

  In the embodiment of the present invention, the 10-row auger filling apparatus 1 has been described as an example. However, the embodiment of the present invention is also applied to auger filling apparatuses having 2 to 9 rows and 11 or more rows. be able to.

  Note that the above-described embodiment shows an example for embodying the present invention, and the matters in the embodiment and the invention-specific matters in the claims have a corresponding relationship.
