  The present invention relates to an automatic packaging machine that automatically fills and wraps raw materials (contents) using a packaging film (packaging material), and enables a predetermined amount of granular raw materials to be fed into an automatic packaging machine. The present invention relates to a granular raw material supply apparatus.

  Conventionally, in an automatic packaging machine that automatically fills and wraps granular raw materials (contents), the raw materials are temporarily stored in the hopper of the automatic packing machine, and the stored raw materials are preset in accordance with the bag making operation. After being measured to the filled amount, this raw material is supplied into the bag through the input port of the finished packaging bag, and then the input port is sealed (heat sealed) and separated into individual packaging bags.

  In such a granular raw material supply device for an automatic packaging machine described in Patent Document 1, in order to measure and supply irregular granular raw materials such as bakery of instant food and plant seeds to the automatic packaging machine In addition, the following configuration is adopted. That is, the raw material discharged from the discharge part of the hopper is continuously cut out from the downwardly inclined cutting cylinder rotating in the same direction by the rotating means, dropped into the receiving member, and measured by the measuring instrument. Thereafter, when the predetermined weight is reached, the opening / closing lid of the receiving member is opened by the opening / closing means, and the measured raw material is discharged. As a result, an accurate predetermined amount can be cut out, and the high cost and trouble of defective products caused by excessive or undercutting of the weighing object (raw material) can be eliminated.

Japanese Patent Laid-Open No. 08-226845

  However, since such a conventional raw material supply device cuts out an irregular granular raw material by the same direction of rotation and downward inclination by a cutting cylinder, the raw material tends to solidify or the particles tend to get entangled.

  Embodiments of a granular raw material supply apparatus according to the present invention will be described below with reference to the drawings. FIG. 1 is a front view of a row of granular raw material supply apparatuses embodying the present invention, and FIG. 2 is a left side view of the row of granular raw material supply apparatuses embodying the present invention. First, the present invention was implemented. A description will be given of the configuration of a row of granular material supply devices. That is, as shown in FIG. 1 and FIG. 2, in a row of granular raw material supply apparatus 1, 10 is a hopper in which non-uniform particulate raw material is stored, and 11 is a holding device while adjusting the inclination of the hopper. The tilt adjusting base 13 (see FIG. 2) is inserted in a posture inclined downward in the hopper 10, first a scraping metal (not shown in FIG. 1) for cutting out the granular material in the hopper 10, and 14 is a scraping metal 13. It is a scraper that moves along with it and cuts out the granular material in the hopper 10 while conveying it.

  The scraping bar 14 has an inclined barbed structure having a substantially U-shaped cross-section with an open upper surface, and is connected to the scraping bar 13 by a connecting bracket 12. Further, a heel side drive transmission gear 15 is fitted into the scraping bar 14 and is gear-coupled with a motor side drive transmission gear 16 attached to a driving motor 17 for rotating the scraping bar 14 by a certain angle. .

  A feeder 18 is disposed immediately below the inclined outlet of the scraping bar 14, and the feeder 18 conveys the granular raw material received from the scraping bar 14 to the right in FIG. A supply shutter 19 is disposed immediately below the outlet of the feeder 18, and this supply shutter 19 is connected to a measuring instrument 20 so that the weight of the granular raw material falling into the supply shutter 19 can be measured. . Moreover, each said member is constructed | assembled on the base 23, Below this base 23, the controller 21 which performs various control of the granular raw material supply apparatus which concerns on this invention, and various input / output means of the controller 21 An operation panel 22 is provided.

Next, the operation of the single row granular material supply apparatus 1 embodying the present invention shown in FIGS. 1 and 2 will be described below.
(1) A non-uniform granular raw material (not shown) is stored in the hopper 10, and the granular raw material in the hopper 10 is compressed downward in the hopper 10 due to gravity.

  (2) Here, the movement of the scraping bar 14 will be described. The aforementioned heel side drive transmission gear 15 is fitted on the root end side of the scraped ridge 14, and a motor side drive transmission gear 16 is gear-coupled to the heel side drive transmission gear 15. The turning power is transmitted to the scraper 14. When the driving motor 17 rotates the motor-side drive transmission gear 16 in the left direction (counterclockwise direction) in FIG. 1, the heel-side drive transmission gear 15 rotates the scraper 14 in the right direction (clockwise direction) ( This is referred to as normal rotation), but when it is rotated in the right direction, the scraping rod 14 is rotated in the left direction (this is referred to as reverse rotation). The drive motor 17 rotates to the left by a preset angle under the control of the controller 21, and then immediately changes the rotation direction and rotates to the right by a preset angle. This turning rotation operation is repeated. Then, the scraper bar 14 connected to the gear similarly rotates in the forward direction by a preset angle, and then immediately changes the rotation direction to rotate in the reverse direction by a preset angle, This turning and turning operation is repeatedly performed to become a swinging operation. As a result, this swinging operation is such that when the rod 14 itself turns back in the rotational direction, a stirring force in the lateral direction of 90 degrees is applied to the material being conveyed, and the property that it is easily solidified or easily entangled. The raw materials to be separated are separated apart, and a powerful unraveling action is added to the raw materials.

  (3) Note that the amount of rotation of the scraping rod 14 in the rightward normal rotation and the counterclockwise rotation in the left direction is that the scraping rod 14 has a generally U-shaped cross-sectional structure with the upper surface opened. The amount of rotation that prevents the granular material from spilling out from the open portion is defined as the operating range. In addition to the amount of rotation of the scraping bar 14, the rotational speed of the scraping bar 14 in the forward and reverse direction and the inclination angle of the scraping bar 14 by the tilt adjusting base 11 are values that determine the amount of action to be solved in the swinging operation. become. That is, the larger the rotation amount of the scraping bar 14, the higher the rotation speed of the scraping bar 14, the greater the amount of unwinding action on the granular material, and the lower the inclination angle of the scraping bar 14, the more the granular material is conveyed. Although the amount is reduced, the number of rocking operations is increased, so that the amount of unwinding action given to the granular raw material is increased.

  (4) In accordance with the movement of the scraping bar 14, the scraping metal 13 connected by the connecting metal 12 repeats the swinging operation (forward / reverse rotating operation) inside the hopper 10, thereby the hopper The granular material inside 10 is cut out inside the raft 14. The granular raw material cut out inside the scraper 14 is subjected to a strong unwinding action by the forward and reverse swinging motion of the scraper 14 as described in (2) and (3) above, and is separated into separate parts. 18 is sent.

  (5) Next, the above-described feeder 18 gradually drops the granular raw material into the supply shutter 19 by the vibration action while further diffusing the granular raw material received from the above-described scraping bar 14.

  (6) The meter 20 is connected to the supply shutter 19, and when the preset measurement value is reached, the drop port of the supply shutter 19 is opened (not shown) and the meter is correctly weighed to the next process device. A granular raw material is sent out.

  (7) It should be noted that the controller 21 provided in the granular raw material supply apparatus 1 includes the scraping operation of the scraper 14, the feeding operation of the feeder 18, the measuring operation of the measuring device 20, and the feeding operation of the supply shutter 19. The entire apparatus 1 is controlled, and various settings, various instructions, and various display items for the controller 21 are configured to be implemented via the operation panel 22.

  Here, in the present embodiment, a gap is not generated between the insertion portion (scraping metal 13) of the scraping bar 14 inserted into the bottom portion in the hopper 10 and the bottom surface 10 a in the hopper 10. As shown in FIGS. 2, 14, and 15, a guide member 10A is provided.

  That is, around the scraped metal fitting 13 that is disposed facing the bottom of the hopper 10, the upper part is opened to guide the granular raw material to the scraped metal fitting 13, and the lower part of the scraped metal fitting 13 that is oscillated. A guide member 10A configured to cover the outer periphery is provided.

  10 A of this guide member is for making the granular raw material accommodated in the hopper 10 lead to the scraping metal fitting 13 without staying, and the bottom face 10a (inner side surface of the hopper 10) of the hopper 10, It is comprised so that a clearance gap may not arise between each side surface 10b, 10c, 10d, 10e (inner side surface of the hopper 10).

  That is, the guide member 10A is disposed at the bottom of the hopper 10, and is formed so that the lowest value of the guide surface 10B of the guide member 10A is equal to or higher than the lowest value of the outer shape of the scraped metal fitting 13. In addition, the guide surface 10B is inclined so as to be lowered toward the scraping bar 14 (the scraping bracket 13) so that the granular raw material can move in the direction of the scraping bracket 13 without stagnation.

  In the present embodiment, since the guide member 10A is provided, it is possible to prevent the particulate material from staying in the hopper 10, and thus to the particulate material by staying in the hopper 10. Adverse effects can be avoided.

  As described above, according to the present embodiment, although it is a relatively simple and low-cost configuration, it is difficult to cut out with the conventional granular raw material supply apparatus, or the particles are easily entangled. It is possible to provide a granular raw material supply device capable of supplying a raw material having properties to an automatic packaging machine in a predetermined amount and preventing the granular raw material from staying in the hopper.

Further, a plurality of heel side drive transmission gears 35 are fitted into the plurality of scraping rods 34... And a plurality of motor sides attached to a plurality of drive motors 37 for rotating the plurality of scraping rods 34. The drive transmission gear 36 is gear-coupled.

  A plurality of feeders 38 are arranged immediately below the inclined outlets of the plurality of scraping rods 34, and the plurality of feeders 38 are conveyed by vibration while diffusing the granular raw materials received from the plurality of scraping rods 34. doing.

  Further, a plurality of supply shutters 39 are arranged immediately below the outlets of the plurality of feeders 38, and the plurality of supply shutters 39 are connected to a plurality of measuring devices 40 and are connected to the plurality of supply shutters 39. It is possible to measure the weight of the granular raw material that has fallen on the surface.

  A collective shutter 44 is arranged immediately below the drop openings of the plurality of supply shutters 39... And receives the total of the granular raw materials sent from the plurality of supply shutters 39 and sets the next process device at a preset timing. A collective feed is performed.

  Each of the above members is constructed on a base 43, and under this base 43, there are a controller 41 that performs various controls of the granular raw material supply device, and an operation panel 42 that is various input / output means of the controller 41. Has been deployed.

  Next, the operation of a plurality of rows of granular raw material supply apparatuses embodying the present invention shown in FIGS. 3 and 4 will be described below.

  (1) Non-uniform granular raw material is stored inside the hopper 30, and the granular raw material inside the hopper 30 receives gravity and is compressed downward in the hopper 30.

  (2) Here, the movement of the plurality of scraping rods 34 will be described. A plurality of heel-side drive transmission gears 35 are fitted into the plurality of scraping rods 34, and a plurality of motor-side drive transmission gears 36 are gear-coupled to the plurality of heel-side drive transmission gears 35. The rotational power of the drive motors 37 is transmitted to the plurality of scraping rods 34. When the plurality of drive smokes 37 are rotated leftward in FIG. 3, the scraping bar 34 rotates rightward (this is referred to as normal rotation), and when it is rotated rightward, the scraping bar 34 moves leftward. Is rotated (this is referred to as reverse rotation).

The plurality of drive motors 37... Rotate leftward by a preset angle under the control of the controller 41, and then immediately change the rotation direction and rotate rightward by a preset angle. The turning rotation operation is repeated. Similarly, the plurality of scraped rods 34 connected to the gear are rotated in the forward direction by a preset angle in the same manner, and immediately thereafter, the direction of rotation is changed to rotate in the reverse direction by the preset angle. This turning and turning operation is repeatedly performed to become a swinging operation. As a result, this swinging operation is easily entangled due to the tendency that the ridges 34... The raw materials having properties are separated apart, and a powerful unraveling action is added to the raw materials.

  (3) It should be noted that the amount of rotation of the plurality of scraping rods 34... In the right direction (this is referred to as normal rotation) and left direction (this is referred to as reverse rotation) is the plurality of scrapes. Since the ridge 34 has a ridge structure having a substantially U-shaped cross section with the upper surface open, the rotation range in which the granular raw material does not spill out from the open portion is set as the operation range. In addition to the amount of rotation of the plurality of scraping rods 34, the rotational speed of the plurality of scraping rods 34 and the inclination angle of the plurality of scraping rods 34 by the inclination adjusting base 31 are also the amount of action to be solved in the swinging operation. It becomes the value which decides. That is, the larger the amount of rotation of the scraping bar 34, the higher the rotational speed of the scraping bar 34, the greater the amount of action for the granular material, and the lower the inclination angle of the scraping bar 34, the more the raw material is conveyed. Although wrinkles are reduced, the number of rocking operations is increased, so that the amount of unwinding action on the granular raw material is increased.

  (4) In accordance with the movement of the plurality of scraping rods 34, the plurality of scraping brackets 33 connected by the plurality of connecting brackets 32 ... swing inside the hopper 30, thereby The granular raw material inside the hopper 30 is cut out into the inside of the plurality of scraped ridges 34. The granular raw material cut into the inside of the plurality of scraped barks 34... Is subjected to a powerful unraveling action by the swinging motion of the plurality of scraped barks 34 described in (2) and (3) above. Separated and fed into a plurality of feeders 38.

  (5) The plurality of feeders 38... Gradually diffuse the granular raw materials into the plurality of supply shutters 39... By oscillating action while diffusing the granular raw materials received from the plurality of scrapers 34.

  (6) A plurality of measuring instruments 40 are connected to the plurality of supply shutters 39, and the plurality of measuring instruments 40 perform a measuring operation until a preset reference value is reached, and each reference value is obtained. In addition, at the fall timing assigned to each supply shutter 39, the drop ports of the plurality of supply shutters 39 are opened to drop the measured raw material in the collective shutter 44.

  (7) When the aggregate shutter 44 reaches the predetermined value to be sent out into the packaging bag set in advance and the total value of the granular raw materials sent out from the plurality of supply shutters 39. Correctly weighed granular raw materials are collected and fed to the process equipment.

  (8) It should be noted that the controller 41 provided in the granular raw material supply apparatus 3 includes a cutting operation of the plurality of scrapers 34, a conveying operation of the plurality of feeders 38, and a measuring operation of the plurality of measuring devices 40. The entire apparatus including the feeding operation of the plurality of supply shutters 39 and the collective feeding operation of the collective shutter 44 is controlled. Various settings, various instructions and various display items for the controller 41 are displayed on the operation panel 42. Implemented via.

  (9) In the plurality of rows of granular raw material supply devices 3 shown in FIGS. 3 and 4, the granular raw material sent to the next process equipment is the sum of the amounts sent from the plurality of rows of granular raw material supply devices 3. Therefore, the time required to reach a predetermined supply amount required in the next process is greatly shortened.

  That is, when the predetermined supply amount required in the next step is performed by the plurality of rows of granular material supply devices 3, the time is a fraction of a time compared to the supply time when performed by the one row of granular material supply devices 1. And can be connected to the latest automatic packaging machines with higher operating speed.

  Here, the unraveling action by the scraping bar 34 will be described in detail. FIG. 5 is a schematic cross-sectional view of the granular raw material supply apparatus 1 or 3 according to the present invention when the scrapers 14 and 34 are in the origin state (initial state), and FIG. 6 is a granular raw material supply apparatus according to the present invention. FIG. 7 is a schematic cross-sectional view when the 1 or 3 scraping bar 14, 34 is rotating in the right direction (forward rotation), and FIG. 7 is the scraping bar 14 of the granular raw material supply apparatus 1 or 3 embodying the present invention. 34 are rotated in the left direction (reverse rotation).

  As shown in FIG. 5, the granular raw material 50 is cut out inside the scraping rods 14 and 34 in the origin state (initial state) before the swinging operation is performed, and this state is immediately after being cut out. Therefore, the raw material 50 is in a partially solidified state or an intertwined state.

Next, as shown in FIG. 6, the scraping rods 14 and 34 are rotated to the right by a preset angle (forward rotation) by the drive motors 17 and 37 geared to the scraping rods 14 and 34. ) And a stirring force of 90 degrees transverse to the conveying direction of the scrapers 14 and 34 is applied to the internal granular material 50.

Next, as shown in FIG. 7, the scraping rods 14 and 34 are immediately turned by a preset angle by changing the direction of rotation by the drive motors 17 and 37 whose gears are connected to the scraping rods 14 and 34. Rotating in the direction (reverse rotation), the stirring force in the lateral direction of 90 degrees is applied to the internal granular raw material 50 with respect to the conveying direction of the scrapers 14 and 34.

  Then, this turning and turning operation is repeatedly performed, and becomes a swinging operation. As a result, this oscillating action is such that when the ridges 14 and 34 themselves turn back in the rotational direction, the agitating force of 90 degrees in the lateral direction is applied to the granular raw material 50 being conveyed, The raw materials having the property of being easily entangled are separated apart, and a powerful unraveling action is added to the granular raw material 50.

  As an example of this granular raw material 50, it is conceivable to use kizaminori, tea leaves, instant foods (dried meat, dried vegetables, etc.), sprinkles, plant seeds, granular confectionery, drugs, screws and the like. Depending on the nature of the material, the controllers 21 and 41 of the granular raw material supply devices 1 and 3 perform the swinging operation while arbitrarily and freely changing the rotation amount (rotation angle) and rotation speed of the scraping rods 14 and 34. I have control.

  In addition to the example in which the swing operation is set to a fixed amount of rotation (rotation angle) and rotation speed, the rotation amount (rotation angle) and rotation speed are varied during the swing operation. However, if the rotation amount (rotation angle) and rotation speed are varied during this swinging motion, the stirring force applied to the granular material will be accelerated and decelerated, resulting in a more complicated unraveling action. Realization is possible.

  FIG. 8 illustrates an example in which the stirring rods 60 are respectively attached to the scraping metal fittings 13 and 33 when the scraping rods 14 and 34 of the granular raw material supply apparatuses 1 and 3 according to the present invention are in the origin state (initial state). FIG. 9 is a schematic front view, and FIG. 9 shows scraping metal fittings 13 and 33 when the scraping rods 14 and 34 of the granular raw material supply apparatuses 1 and 3 according to the present invention are rotated in the right direction (forward rotation). It is the schematic front view explaining the example which attached the stirring rod 60 to.

  As shown in FIGS. 8 and 9, the scraping rods 14 and 34 in the origin state (initial state) before the swinging operation (reciprocating rotation operation) are inclined downward in the hoppers 10 and 30. The inserted scraping metal fittings 13 and 33 are attached, and the scraping metal fittings 13 and 33 swing inside the hoppers 10 and 30 in order to cut the granular raw material 50 in the hoppers 10 and 30 into the scraping rods 14 and 34. It is operating. In FIG. 8, a stirring bar 60 is attached to each of the scraping metal members 13 and 33 in order to strengthen the stirring operation in the hopper in conjunction with the swinging operation.

  Then, as shown in FIG. 9, when the scraping metal fittings 13 and 33 inserted into the hoppers 10 and 30 are rotated to the right (forward rotation) by the swinging operation (reciprocating rotation operation), the attached stirring rods are provided. 60 also rotates to the right (forward rotation) by a preset angle. As a result, a strong stirring motion is generated by the stirring rod 60 inside the hoppers 10 and 30, and more granular raw material is scraped out from the hoppers 10 and 30 into scrapes 14 and 34.

  FIG. 10 is a schematic side view for explaining an example in which a raw material regulating rod 70 is provided inside the scraping rods 14 and 34 of the granular raw material supply apparatuses 1 and 3 embodying the present invention. As shown in FIG. 10, the granular raw material 50 cut out from the hoppers 10, 30 is conveyed from the left side to the right side of the rafts 14, 34. 34 is inclining as shown in the figure, and the scraping rods 14 and 34 are moving by the swinging motion.

  And when this granular raw material 50 has the property which is easy to harden more easily, or it is easy to get entangled, the case where sufficient unraveling action is not made only by the rocking | fluctuation operation | movement of the scrapers 14 and 34 can be considered. For this reason, as shown in FIG. 10, the raw material regulating rod 70 supported by the granular raw material supply device base 71 is inserted from the opened portion of the upper surface of the inclined main body in the scraping rods 14, 34, and the scraping rod 14, At the same time, the swelled portion of the granular raw material 50 in 34 is removed, and at the same time, a stirring action is applied to the removed granular raw material 50.

  By such a granular raw material flattening operation by the raw material regulating rod 70, a flat granular raw material 51 having a uniform height in the vertical direction with respect to the granular raw material 50 moving inside the scraping rods 14 and 34 is obtained. This can be achieved by strengthening the unraveling action on the granular raw material 50 having a stronger tendency to solidify or to be entangled, and the scraping rods 14 and 34 of the granular raw material supply apparatuses 1 and 3. The quantitative fluctuation of the granular raw material 50 sent out thereafter is further reduced.

  In addition, the attachment portion of the raw material regulating rod 70 is provided with a raw material regulating rod vertical adjustment fitting 71 that can adjust the height of the attached raw material regulating rod 70, The height of the flat granular material 51 can be adjusted.

  Here, also in the plurality of rows of granular raw material supply devices 3 according to the present embodiment, the insertion portions (the plurality of scraping metal fittings 33) of the plurality of scraping rods 34 inserted into the bottom of the hopper 30 and the inside of the hopper 30 As shown in FIGS. 4, 16, and 17, a guide member 30 </ b> A is disposed so that no gap is generated between the bottom surface 30 a of the first member and the bottom member 30 </ b> A.

  That is, an upper part is opened around each of the plurality of scraping metal fittings 33 arranged facing the bottom in the hopper 30 so as to guide the granular raw material to each scraping metal fitting 33, and is swung. A guide member 30 </ b> A configured to cover the lower outer periphery of each scraped metal fitting 33 is provided.

  10 A of this guide member is for making the granular raw material accommodated in the hopper 30 guide to each scraping metal fitting 33, without staying, and the bottom face 30a (inner side surface of the hopper 30) of the hopper 30 The gaps between the side surfaces 30b, 30c, 30d, and 30e (the inner side surface of the hopper 30) are not formed.

  That is, the guide member 30A is disposed at the bottom of the hopper 30 so that the lowest value of the guide surface 30B of the guide member 30A is equal to or higher than the lowest value of the outer shape of each scraped metal fitting 33. The guide surface 30B is inclined so as to be lowered toward the corresponding scraping bar 34 (scraping bracket 33) so that the granular raw material can move in the direction of each scraping bracket 33 without being stagnant. .

  Since the plurality of rows of granular raw material supply devices 3 according to the present embodiment are configured to include such a guide member 30A, it is possible to prevent the granular raw material from staying in the hopper 30, and thus in the hopper 30. It is possible to avoid adverse effects on the granular raw material due to retention.

  As described above, according to the present embodiment, although it is a relatively simple and low-cost configuration, it is difficult to cut out with the conventional granular raw material supply apparatus, or the particles are easily entangled. It is possible to provide a granular raw material supply device capable of supplying a raw material having properties to an automatic packaging machine in a predetermined amount and preventing the granular raw material from staying in the hopper.

  The embodiment of the present invention is an example for embodying the present invention, and has a corresponding relationship with the invention-specific matters in the claims, but is not limited thereto. Various modifications can be made without departing from the scope of the present invention.

  Here, the modified example is demonstrated using figures for the scraping metal fittings 13 and 33 of the granular raw material supply apparatus which implemented this invention. FIG. 11 is an explanatory view of the structure of the scraped metal fittings 13 and 33 and the scraping rods 14 and 34 of the granular raw material supply apparatus embodying the present invention. FIG. 12 shows the structure of the scraped metal fittings 13 and 33 embodying the present invention. FIG. 13 is a diagram illustrating various types of external shapes of the scraped metal fittings 13 and 33 according to the present invention. As shown in FIG. 11, 10 and 30 are hoppers in which non-uniform granular raw materials are stored, and 13 and 33 are inserted in a posture inclined downward in the hoppers 10 and 30. The scraping metal fittings 14 and 34 for cutting out the granular raw material 50 move along with the scraping metal fittings 13 and 33 to cut out the granular raw material 50 in the hoppers 10 and 30 and convey them.

  The scraped barbs 14 and 34 have an inclined barbed structure having a substantially U-shaped cross-section with an open upper surface, and are connected to the scraped barbers 13 and 33 by connecting brackets 12 and 32. A sectional view taken along the line A-A of the scraped metal fittings 13 and 33 is shown on the illustrated left extension line of the scraped metal fittings 13 and 33. , 34 is a cross-sectional view taken along the line B-B.

  Various examples relating to the cross-sectional shape of the scraped metal fittings 13 and 33 are described in (1) to (4) of the solid 12, and various examples relating to the overall appearance shape of the scraped metal fittings 13 and 33 are illustrated in FIG. (1) to (9).

  That is, as described above, the scraped metal fittings 13 and 33 can be variously modified according to the properties of the granular raw material 50. The specific operation point is that the granular raw material 50 in the hoppers 10 and 30 is used. In the case where the material has a property of being easily solidified, the scraped metal fittings 13 and 33 having projection members for cutting the raw material are selected. For example, (2), (3), (4) in FIG. 12, and (2), (3), (5), (6), (8), (9) in FIG.

  Further, when the granular raw material 50 in the hoppers 10 and 30 has the property of being easily entangled, the scraped metal fittings 13 and 33 having a simple shape are selected so that the raw material does not get entangled with the scraped metal fittings 13 and 33. Yes. For example, it is (1) in FIG. 12 and (1), (4), and (7) in FIG. 13, but these are examples of implementation.
