Various apparatuses are known as apparatuses for filling materials using centrifugal force (see, for example, Patent Document 1 and Patent Document 2). Since these filling devices utilize centrifugal force, even a highly viscous material can be filled. Further, as a method for filling a material using centrifugal force, a method of filling a plurality of containers (containers 30) with a material (liquid crystal L) in one container (storage tank) as in Patent Document 3 is known. ing.

  In the technique described in Patent Document 1, it is difficult to increase the working efficiency because the viscous material is once formed into a rod-like, small-bulb, or thin-film shape and then filled into the discharge container. Moreover, in the technique described in Patent Document 2, the apparatus configuration is easily increased in size, and the number of parts is large, so that there is a possibility that it takes time to clean the parts.

The partition area A1 of the relay member 20 and the second container 120 (the internal space of the second container 120) are communicated with each other.

  Then, the filling device unit 100 is rotated by starting the rotation drive mechanism 200 and the operation of the material filling device 1 is started. When the filling device unit 100 rotates, centrifugal force acts on the material M, and the material M is pressed against the inner surface 112 of the first container 110. By the way, since the inner side surface 112 is an inclined surface facing the upper end side of the first container 110, when the material M is pressed against the inner side surface 112, a force toward the upper end of the first container 110 along the inner side surface 112. Will act. That is, as shown in FIG. 5, the material M moves toward the upper end along the inner side surface 112 while spreading thinly along the inner side surface 112 (while forming a pipe shape). And in this Embodiment, since the upper end of the 1st container 110 is opening, the material M is discharged | emitted from the 1st container 110 through opening of an upper end.

  The filling device unit 100 is configured such that the side surface 22 of the relay member 20 surrounds the upper end (opening) of the first container 110. In other words, in the filling device unit 100, the upper end (opening) of the first container 110 is disposed in the partition region A1. Since the relay member 20 is also rotated, the material M is pressed against the peripheral edge (inner peripheral surface 24) of the partition region A1 under the influence of centrifugal force even in the relay member 20. Therefore, the material M discharged from the opening at the upper end of the first container 110 is held at the peripheral edge of the partition area A1, as shown in FIG.

  In the present embodiment, the inner peripheral surface 24 of the relay member 20 includes a lower region 32 and an upper region 34. The lower region 32 is an inclined surface facing the upper region 34 side, and the upper region 34 is a lower portion. The inclined surface faces the region 32 side. Therefore, the material M transferred to the relay member 20 receives a centrifugal force in the relay member 20 and is pressed against the inner peripheral surface 24, and reaches the boundary region between the lower region 32 and the upper region 34 along the inner peripheral surface 24. You will receive the power of heading. In the present embodiment, since the through hole 30 is formed in the boundary region between the lower region 32 and the upper region 34, the material M receives a force toward the through hole 30 in the partition region A1, and the through hole 30 Through the partition area A1.

  That is, the material M is discharged from the through hole 30 (the material relay pipe 58) as shown in FIG. 7 under the action of the centrifugal force in the partition region A1 of the relay member 20. Here, in the present embodiment, in the filling device unit 100, the partition region A1 and the internal space of the second container 120 are communicated with each other through the through hole 30. Therefore, the material discharged from the through hole 30 is transferred to the internal space of the second container 120.

  That is, in the material filling apparatus 1, the material M stored in the first container 110 is transferred to the peripheral portion of the partition region A <b> 1 of the relay member 20 using centrifugal force, and further, the through hole 30 (the material relay pipe 58 is used). ) To the second container 120, the material M stored in the first container 110 can be filled into the second container 120. From this, it can be said that the relay member 20 is configured to relay the material M at the peripheral edge of the partition region A1 in the step of filling the material M into the second container 120.

  The material filling apparatus 1 includes a chamber 92 and a decompression unit 94 that decompresses the interior of the chamber 92. Therefore, the step of filling the second container 120 with the material M stored in the first container 110 can be performed in a state where the inside of the chamber 92 is decompressed. Specifically, after the first and second containers 110 and 120 are held by the filling device unit 100, the inside of the chamber 92 is decompressed, and then the motor 70 is driven to fill the material M in a decompressed environment. Processing can be performed.

(3) Material Filling Method Next, a material filling method according to the present embodiment will be described with reference to FIG. Here, FIG. 8 is a flowchart for explaining the material filling method.

  In the material filling method according to the present embodiment, as shown in FIG. 8, the filling device unit 100 holds the first container 110 and the second container 120 in which the material M is stored (in the first container holding unit 10). A step (step S110) of holding the first container 110 and holding the second container 120 in the second container holding unit 40, and a step of filling the second container 120 with the material M by rotating the filling device unit 100. (Step S120).

  Here, when the filling device unit 100 (the first container holding unit 10) holds the first container 110, the first container 110 is placed so that the upper end of the first container 110 is disposed in the partition region A1. Hold. Further, when the second container 120 is held by the filling device unit 100 (second container holding portion 40), the partition region A1 and the second container 120 are connected via the through holes 30 (the through holes 30 and the relay members 58). Communicate with the interior space.

  The step of filling the material M into the second container 120 (step S120) is a step of discharging the material M from the upper end of the first container 110 and holding it on the relay member 20 (periphery of the partition region A1) (FIG. 4). To the material M held by the relay member 20 and a process of transferring the material M to the second container 120 via the through hole 30 (see FIGS. 6 and 6). 7).

(4) Material M
The material M applicable to the present embodiment is not particularly limited as long as it behaves as a fluid, and its composition and use are not particularly limited. Examples of the material M include an adhesive, a sealant, a liquid crystal material, a solder paste, a curable resin material used for molding, a dental impression material, a dental cement (such as a hole filling agent), a highly viscous liquid medicine, Various materials such as granular materials can be applied.

(5) Effects Hereinafter, functions and effects achieved by the present embodiment will be described.

  According to the material filling apparatus 1, the second container 120 is filled with the material M stored in the first container 110 using centrifugal force. Therefore, a large force can be applied to the material M, so that even the highly viscous material can be efficiently filled (transferred) into the second container 120. Further, since a large force is applied to the material M, the amount of the material remaining in the first container 110 and the relay member 20 can be extremely reduced, and the material M can be efficiently used.

  Moreover, according to the material filling apparatus 1, all material filling processes can be realized using centrifugal force. Therefore, it is not necessary to use a member such as a spatula at the time of filling the material, so that the material filling process can be performed so that impurities are not mixed into the material.

  Further, according to the material filling apparatus 1, during the material filling process, the material M contacts only the relay member 20 (the relay member 20 and the material relay pipe 58) except for the first and second containers 110 and 120. Therefore, the number of parts that require cleaning can be reduced.

  Further, according to the material filling apparatus 1, the first container 110 has an inclined surface with the inner side surface 112 facing the upper end side, and the upper end (opening) is relayed when held by the first container holding unit 10. What is necessary is just to be comprised so that arrangement | positioning in division area A1 of the member 20 is possible, and the shape is not limited. Therefore, it is possible to provide a material filling device that can correspond to various containers (first container 110).

  Further, according to the material filling device 1, when the material M is discharged from the first container 110, the material M is in a thinly expanded state and moves toward the upper end (opening) along the inner side surface 112. (See FIG. 4). That is, the material M receives a centrifugal force with a small thickness. Therefore, even when there are bubbles mixed in the material M, the bubbles can be released by the action of centrifugal force, so that the material M can be defoamed in the material filling step.

  In the present embodiment, the material filling apparatus 1 includes a chamber 92 and a decompression unit 94. For this reason, bubbles mixed in the material M can be efficiently discharged during the material filling process.

  Further, in the present embodiment, a plurality of through holes 30 are formed in the relay member 20 (side surface 22), and the internal space of the partition region A <b> 1 and the plurality of second containers 120 through the plurality of through holes 30. And communicated with each other. Therefore, it is possible to provide an efficient material filling apparatus capable of distributing the material M stored in the first container 110 to the plurality of second containers 120 and simultaneously filling the material M. In particular, when the relay member 20 is configured so that the horizontal cross section of the inner peripheral surface 24 is circular, the distance between the center (rotation center) of the relay member 20 and each through-hole 30 is equal, so that a plurality of In the vicinity of the through hole 30, the same amount of force is applied to the material M. Therefore, the same amount of material M can be discharged from each of the plurality of through holes 30, and the plurality of second containers 120 can be filled with the material M evenly. Note that the behavior of the material M in the partition region M is affected by the shape of the inner peripheral surface 24 and the frictional resistance between the inner peripheral surface 24 and the material M. For this reason, the processing accuracy of the relay member 20 is increased, and as the horizontal cross section of the inner peripheral surface 24 approaches a perfect circle, and the surface processing of the inner peripheral surface 24 becomes uniform, the plurality of second containers 120 are filled. Variations in the material M can be reduced. Therefore, even when the first container 110 with low processing accuracy is used, the material M can be uniformly filled into the plurality of second containers 120 by using the relay member 20 with high processing accuracy.

(6) Modified Example Next, a modified example of the present embodiment will be described.

  As a modification of the present embodiment, the filling device unit includes a first state in which the material M transferred to the relay member 20 can be transferred to the second container 120, and a second state in which the material M cannot be transferred to the second container 120. The state can be set to be possible. The material filling unit includes switching means for switching between the first state and the second state. For example, the filling device unit can be configured to have a valve that opens and closes all the material relay pipes 58 and a drive mechanism that drives the valve at a predetermined timing. Note that the drive mechanism can be configured to drive all valves simultaneously.

  In this modification, the material filling unit is set to the second state in which the material M cannot be transferred to the second container 120, and the material filling process is started. In the filling device unit 100 set to the second state, since the material is not discharged from the relay member 20, the material M transferred to the relay member 20 is held by the relay member 20 until the material filling unit is switched to the first state. Will be. In this modification, the valve is driven at a predetermined timing to release the material relay pipe 58, and transfer (filling) of material from the relay member 20 to the second container 120 is started.

  According to this modification, after the predetermined amount of material M is transferred to the relay member 20, the transfer of the material M from the relay member 20 to the second container 120 can be started. Therefore, since it becomes possible to start the transfer of the material M to the second container 120 after stabilizing the behavior of the material in the relay member 20, the material M is uniformly distributed to the plurality of second containers 120. Can be dispensed and filled. In particular, if all the valves are driven at the same time, the material distribution accuracy can be increased.

  As another modification, a material filling process is performed using the relay member 20 in a state where some of the plurality of through holes 30 (material relay pipes 58) are closed, and the filling device unit 100 is It is possible to configure using a first container holding part capable of holding a plurality of first containers 110. According to these modified examples, the material filling device can be used so as to correspond to the material M and the desired amount of the second container 120. Alternatively, a relay member having only one through hole 30 can be used. Alternatively, as shown in FIG. 9, it is also possible to use a relay member 21 configured such that the horizontal cross section of the inner peripheral surface is a polygon (regular polygon). In the example shown in FIG. 9, the horizontal cross section of the inner peripheral surface of the relay member 21 is a quadrangle (square). And in the relay member 21, the some through-hole 31 is formed in the vertex of a horizontal cross section. According to the relay member 21, the through hole 31 is arranged at a position farthest from the center of the relay member 21 in the horizontal cross section, that is, a position where the centrifugal force is the largest. Therefore, since the centrifugal force that acts on the material M in the horizontal plane is directed to the through hole 31, efficient material filling processing can be performed. Alternatively, a container having a rectangular horizontal cross section on the inner side surface can be used as the first container (not shown).

2. Second Embodiment Hereinafter, a second embodiment to which the present invention is applied will be described with reference to FIG. In addition, FIG. 10 is a timing chart which shows the rotation speed of the filling apparatus unit 100 in this Embodiment. Moreover, since the structure of the material filling apparatus in this Embodiment can employ | adopt the same structure as the above-mentioned material filling apparatus 1, the description is abbreviate | omitted.

(1) Operation of Material Filling Device and Material Filling Method In the present embodiment, the material filling device (control means) changes the rotation speed of the filling device unit 100 during the process of transferring the material M to the second container 120. To perform the process. Specifically, the material filling apparatus performs a process of reducing the rotational speed of the filling apparatus unit 100 and then increasing it during the process of transferring the material M to the second container 120.

  That is, in the present embodiment, as shown in FIG. 10, the rotational speed of the filling device unit 100 is increased until the rotational speed of the filling device unit 100 reaches the first rotational speed (w1), and then the filling device unit. The rotational speed reduction process for reducing the rotational speed of the filling device unit 100 until the rotational speed of 100 becomes the second rotational speed (w2), and the rotational speed of the filling device unit 100 becomes the first rotational speed (w1). Until the rotational speed of the filling device unit 100 is increased, the rotational speed increasing process is repeated. Note that at least the first rotational speed (w1) is a value sufficient for the material M to rise up the first container 110 and be discharged from the upper end, and the material held in the first container 110 is the through hole 30. This value is sufficient to be transferred to the second container 120 via the. The specific value of the first rotation speed (w1) can be derived by experiment.

  And in this Embodiment, as shown in FIG. 10, when predetermined time (t) passes since the rotation start of the filling apparatus unit 100, the process which stops rotation of the filling apparatus unit 100 is started. Here, the predetermined time (t) is a time until the filling process of the material M into the second container 120 is completed, and a specific value can be derived by an experiment.

(2) Effects Hereinafter, functions and effects achieved by the present embodiment will be described.

  As described above, in the present embodiment, in the process of transferring the material M from the relay member 20 to the second container 120, the rotation speed of the filling device unit 100 (relay member 20) is changed (see FIG. 10). . That is, in the first container 110, the relative rotational speed between the material M and the side surface 22 (inner peripheral surface 24) of the relay member 20 can be adjusted, and the material M is moved around the relay member 20 (partition area A1). Can be moved in the direction. Therefore, it is possible to prevent the material M from staying in the relay member 20 (a region between the through holes 30 in the side surface 22).

  Further, by adjusting the relative rotational speed between the material M and the filling device unit 100 (the relay member 20), the distribution of the material M in the circumferential direction of the side surface 22 can be leveled in the relay member 20. . Therefore, the pressing force acting on the material M in the vicinity of each through hole 30 can be leveled, and the variation in the filling amount of the material M for each second container 120 can be reduced.

  Further, since the magnitude of the centrifugal force acting on the material M changes when the material M is transferred to the second container 120, the material M is prevented from being clogged in the through hole 30 (material relay pipe 58). The material M can be filled so that the material M is not centrifuged.

(3) Modified Example Next, a modified example of the present embodiment will be described.

  As a modification of the present embodiment, in the step of transferring the material M held by the relay member 20 to the second container 120, the number of rotations of the filling device unit 100 (material transfer unit) is set as shown in FIGS. As shown in the timing chart of FIG. That is, as shown in the timing chart of FIG. 11, immediately after the rotation speed of the filling device unit 100 reaches the first value (w1), a process for reducing the rotation speed is started, and the rotation of the filling device unit 100 is started. It is also possible to start processing for stopping the filling device unit 100 after a predetermined time (t) has elapsed from the start. Alternatively, as shown in the timing chart of FIG. 12, even after the rotation speed of the filling device unit 100 (material transfer unit) reaches the first value (w1), the rotation speed is continuously increased, and the filling device unit 100 It is also possible to start the process of stopping the filling device unit 100 after a predetermined time (t) has elapsed since the start of rotation.

  Alternatively, the process of changing the rotation speed of the filling device unit 100 (material transfer unit) to at least one of just before the start of the transfer of the material M to the second container 120 and immediately before the transfer ends ( It is also possible to perform at least one of the process of decreasing and the process of increasing. Note that the timing of starting and ending the transfer of the material M to the second container 120 can be derived in advance by experiments.

3. Third Embodiment Hereinafter, a third embodiment to which the present invention is applied will be described with reference to FIGS. 13 and 14. In addition, FIG. 13 is a timing chart which shows the rotation speed of the filling apparatus unit 100 in this Embodiment. FIG. 14 is a flowchart showing a material filling method in the present embodiment. Moreover, since the structure of the material filling apparatus in this Embodiment can employ | adopt the same structure as the above-mentioned material filling apparatus 1, the description is abbreviate | omitted.

(1) Operation of Material Filling Device and Material Filling Method In the present embodiment, the material filling device (control means) causes the filling device unit 100 to rotate at the first rotation speed during the process of rotating the filling device unit 100. Then, a process of rotating the filling device unit 100 at the second rotational speed is performed. Here, the first rotation speed is a value at which the material M is not discharged from the first container 110. Further, the second rotational speed is a value at which the material M is discharged from the first container 110, and is a value larger than the first rotational speed. The second number of revolutions may be set to a value sufficient to transfer the material M to the second container 120. Note that the values of the first and second rotational speeds can be set by experiment.

  The rotation speed of the filling device unit 100 in the present embodiment can be set as shown in the timing chart of FIG. That is, for a predetermined time (t3) from the start of rotation of the filling device unit 100, the filling device unit 100 is rotated at a rotation speed equal to or lower than the first rotation speed (w3), and then the filling device unit 100 is rotated at the second rotation speed (w4). Rotate with Then, after a predetermined time (t4) elapses from the start of rotation of the filling device unit 100, processing for stopping the rotation of the filling device unit 100 is started.

  Here, the first rotation speed (w3) is a value at which the material M is not discharged from the first container 110. The predetermined time (t3) is a time sufficient for the height of the material M contacting the inner side surface 112 to be constant over the entire circumference of the inner side surface 112. The second rotation speed (w4) is a value at which the material M is discharged from the first container 110. Note that the second rotational speed (w4) may be a value sufficient to fill the second container 120 with the material M. The predetermined time (t4) is a time sufficient to fill the second container 120 with the material M. Further, specific values of the first rotation speed (w3), the second rotation speed (w4), and the predetermined time (t3) and the predetermined time (t4) can be derived by experiments.

  That is, in the present embodiment, in the step of filling the material M into the second container 120, as shown in FIG. 14, the filling device unit 100 so that the material M is not discharged from the first container 110 for an initial predetermined time. To make the height of the material M in contact with the inner side surface 112 of the first container 110 constant over the entire circumference of the inner side surface 112 (step S122), and then the material M is changed to the first level. And a second step (step S124) for discharging from one container 110.

(2) Effect In the present embodiment, before the step of discharging the material M from the first container 110 (second step), the step of making the height of the material M constant in the first container 110 (first step) Step). Thereby, the material M can be discharged simultaneously from the entire circumference of the opening at the upper end of the first container 110. Therefore, the material M spreads in the relay member 20 while keeping its outer shape circular (concentrically with the opening), and can contact (almost) all the through holes 30 simultaneously. Therefore, variation in the amount of the material M discharged from each of the plurality of through holes 30 can be reduced, and the plurality of second containers 120 can be filled with the material M evenly.

  In particular, according to the present embodiment, even when the material M is unevenly distributed in the first container 110, the process of evenly distributing and filling the material M into the plurality of second containers 120 is performed in a short time. It becomes possible. Therefore, even a material that has been stirred and defoamed by a so-called rotation / revolution type stirring and defoaming apparatus can be equally distributed and filled in the plurality of second containers 120. Specifically, as a rotation / revolution type stirring and defoaming apparatus which is currently mainstream, as shown in FIG. 15A, a storage container 900 containing a material M is centered on a revolving axis L1 extending vertically. 2. Description of the Related Art An apparatus that is configured to rotate around a rotation axis L2 that obliquely intersects with a revolution axis L1 is known. In this apparatus, since a high centrifugal force acts on the material M, the material M is collected in a region farthest from the revolution axis L1, and the material is unevenly distributed in the storage container 900. When the viscosity of the material M is high, the material M does not flow greatly even after the storage container 900 is taken out from the stirring and defoaming device. Therefore, as shown in FIG. In some cases, the material is unevenly distributed.

  By the way, according to this modification, the process for making the height of the material M uniform is performed in the first container 110. For this reason, after the material M stored in the first container 110 is processed by the rotation / revolution type stirring and defoaming device, the material M filling processing (rotation driving of the filling device unit 100) is immediately started. In addition, the material M can be evenly distributed and filled in the plurality of second containers 120. In the example shown in FIGS. 15A and 15B, a lid is attached to the storage container 900, which can prevent the material M from leaking during stirring and defoaming. In addition, since a through hole is formed in the center of the lid, if the storage container 900 is rotated and revolved in a reduced pressure atmosphere, the material M is stirred and degassed while the inside of the storage container 900 is decompressed. Therefore, high defoaming performance can be realized.

(3) Modified Example Next, a modified example of the present embodiment will be described.

  In this modification, in the step of filling the material M, the rotation speed of the filling device unit 100 is controlled as shown in the timing chart of FIG. That is, in the present modification, in the first step (step S122), the rotation speed of the filling device unit 100 is changed (a process for decreasing the rotation speed and a process for increasing the rotation speed are repeated). According to this, it becomes possible to prevent the material M from being centrifuged in the first step. Further, since the material M easily spreads in the circumferential direction of the first container 110 due to the influence of the inertial force acting on the material M, the height of the material M can be made constant efficiently. In addition, the number of times of performing the process of reducing the rotational speed and the process of increasing the rotational speed, the amount of change of the rotational speed and the rate of change are not particularly limited, and can be appropriately set according to the characteristics of the material M and the apparatus. Specific values can be derived by experiment. As another modified example, in the step of filling the material M (first step), as shown in the timing chart of FIG.

4). Fourth Embodiment Hereinafter, a fourth embodiment to which the present invention is applied will be described with reference to FIGS.

(1) Configuration of Material Filling Device The material filling device according to the present embodiment has a filling device unit 101. In the filling device unit 101, as illustrated in FIGS. 18 to 19B, the relay member 20 is configured such that the lower region 32 is inclined at a steeper angle than the inner side surface 113 of the first container 110. That is, as shown in FIG. 19A, the angle formed by the imaginary straight line extending horizontally and the lower region 32 is a1, and the angle formed by the imaginary straight line extending horizontally and the inner side surface 113 as shown in FIG. If a2, then the relationship of a2 <a1 is satisfied.

  (2) Operation of material filling apparatus and material filling method

  During the process of rotating the filling device unit 101, the material filling device (control means) rotates the filling device unit 101 at the first rotational speed for an initial predetermined time, and then turns the filling device unit 101 to the second rotational speed. Rotate with. Here, as shown in FIG. 20, the first rotational speed is a value at which at least a part of the material M is discharged from the first container 110 and transferred to the relay member 20, and is transferred to the relay member 20. The material M is a value that does not contact the through hole 30 (opening). That is, when the filling device unit 101 is rotated at the first rotation speed for a predetermined time, at least a part of the material M moves to the relay member 20, but the upper end of the material M is the opening position of the through hole 30 in the relay member 20. Will be maintained at a lower position (see FIG. 20). As described above, in the material filling device 1, since the lower region 32 is inclined at a steeper angle than the inner side surface 113, an upward force (component force) received by the material M in the relay member 20 is obtained. The upward force (component force) received by the material M in the first container 110 can be made smaller. Therefore, according to the material filling apparatus 1, although the material M is discharged | emitted from the 1st container 110, the conditions (rotation speed) by which the height of the material M is maintained below a predetermined value within the relay member 20 (compartment area | region A1). It becomes easy to find. Further, the second rotational speed is a value sufficient for the material M to be discharged from the first container 110, and is a value larger than the first rotational speed. Therefore, by rotating the filling device unit 101 at the second rotational speed, the material M is filled in the second container 120 as shown in FIGS. Note that the values of the first and second rotational speeds can be set by experiment.

  The rotation speed of the filling apparatus unit 101 in the present embodiment can be set as shown in the timing chart of FIG. That is, the filling device unit 101 is rotated at a speed equal to or lower than the first rotation speed (w5) for a predetermined time (t5) from the start of rotation of the filling device unit 101, and then the filling device unit 101 is rotated at the second rotation speed (w6). Rotate.

  Here, the first rotation speed (w5) is a value in which at least a part of the material M is discharged from the first container 110 and the material M does not contact the through hole 30 in the relay member 20. Further, the second rotation speed (w6) is a value sufficient to transfer and fill the material M into the second container 120. The predetermined time (t5) is a time sufficient for the height of the material M in contact with the lower region 32 to be constant over the entire circumference of the relay member 20 (side surface 22), and the material M penetrates. It is a value that does not contact the hole 30. Specific values of the first rotation speed (w5), the second rotation speed (w6), and the predetermined time (t5) can be derived by experiments.

  That is, in the present embodiment, in the step of filling the material M into the second container 120, as shown in FIG. 24, at least a part of the material M is discharged from the first container 110 and relayed for an initial predetermined time. A first step (see step S126 / FIG. 20) in which the filling device unit 101 is rotated so that the material M is transferred to the member 20 and does not contact the through hole 30 in the relay member 20, and then the material M is changed to the first state. And a second step of transferring and filling the two containers 120 (see step S128 / see FIG. 21 and FIG. 22).

  In the present embodiment, when a predetermined time (t6) has elapsed from the start of rotation of the filling device unit 101, processing for stopping the rotation of the filling device unit 101 is started. Here, the predetermined time (t6) is a time until the filling process of the material M into the second container 120 is completed, and a specific value can be derived by an experiment.

(3) Effect In the present embodiment, before the step of transferring the material M from the relay member 20 to the second container 120 (second step), at least a part of the material M is discharged from the first container 110 and relayed. A step (first step) is performed in which the filling device unit 101 is rotated so that the material M is transferred to the member 20 and the material M does not contact the through hole 30 in the relay member 20. According to this, the process of transferring the material M to the second container 120 can be started after reducing the variation in the height of the material M inside the relay member 20. Therefore, at the start of the process of transferring the material M to the second container 120, the material M can be brought into contact with all the through holes 30 (substantially) at the same time. In other words, the variation in timing at which the through hole 30 and the material M come into contact with each other can be reduced. From this, the transfer of the material M to all the second containers 120 is started (almost) at the same time, and variation in the amount of the material M filled in each of the second containers 120 can be reduced. It becomes possible.

(4) Modification Next, a modification of the present embodiment will be described.

  In the present modification, in the step of transferring the material M to the second container 120, the rotation speed of the filling device unit 101 (relay member 20) is controlled as shown in the timing chart of FIG. That is, in this modification, in the first step, the rotation speed of the filling device unit 101 is changed. Specifically, the process of lowering the rotation speed of the filling device unit 101 and the process of raising it are repeated (at least once, the process of lowering the rotation speed of the filling device unit 101 is performed). According to this, it becomes possible to prevent the material M from being centrifuged in the first step. Moreover, since the material M easily spreads in the circumferential direction of the relay member 20 due to the influence of the inertial force acting on the material M, the height of the material M can be made constant efficiently. In addition, the number of times of performing the process of reducing the rotational speed and the process of increasing the rotational speed, the amount of change of the rotational speed and the rate of change are not particularly limited, and can be appropriately set according to the characteristics of the material M and the apparatus. Specific values can be derived by experiment.

  As another modified example, as shown in FIG. 26, all the material M is transferred into the relay member 20 in the first step (step S126) of the process of transferring the material M to the second container 120. Is also possible. This makes the amount of the material M stored in the first container 110 equal to or less than the volume of the portion below the through hole 30 of the relay member 20 (the volume that can be held by the lower region 32 and the lower flange 26). Can be realized. This makes it difficult for the material M to be unevenly distributed in the relay member 20 during the transfer process to the second container 120, thereby reducing variations in the amount of the material M filled in the second container 120. It becomes possible.

Specifically, the material filling device decreases the rotational speed of the relay member 420 during the process of transferring the material M to the second container 120 and then increases it.

  Specifically, in the present embodiment, the rotational speed of the relay member 420 is increased until the rotational speed of the relay member 420 (material transfer unit) reaches a predetermined value (w7), and then the rotational speed of the relay member 420 is increased. The relay member 420 is stopped by performing a process for reducing the number of revolutions. Then, after the relay member 420 is stopped, the rotation of the relay member 420 is started in the opposite direction, and a rotation speed increasing process for increasing the rotation speed of the relay member 420 is performed. Then, after the rotation speed of the relay member 420 reaches a predetermined value (w7), a reduction process is performed to reduce the rotation speed until the relay member 420 stops. Next, the rotation speed of the relay member 420 is changed to perform the rotation speed increasing process. In this embodiment, in the present embodiment, the rotation speed increase process and the rotation speed decrease process in the first direction (for example, clockwise), and the rotation speed increase process and the rotation speed decrease in the second direction (for example, counterclockwise). It can be said that the process is repeated. That is, in the present embodiment, the rotation direction of the relay member 420 (material transfer unit) is reversed in the process of filling the material M into the second container 120. Note that the predetermined value (w7) is a value sufficient for the material M to move up the first container 110 and be discharged from the upper end, and the material held in the relay member 420 is second through the through hole 30. This value is sufficient to be transferred to the container 120. A specific value of the predetermined value (w7) can be derived by experiment.

  In the present embodiment, when a predetermined time (t7) has elapsed from the start of rotation of the relay member 420 (material transfer unit), processing for stopping the rotation of the relay member 420 is started. Here, the predetermined time (t7) is a time until the filling process of the material M into the second container 120 is completed, and a specific value can be derived by an experiment.

Therefore, the material M can be prevented from staying in the relay member 420. In particular, in the present embodiment, the relative speed between the material M and the relay member 420 can be increased by reversing the rotation direction of the relay member 420 (material transfer unit). Therefore, since the material M can be largely flowed with respect to the relay member 420, the material M is prevented from staying in the relay member 420 and the material M is prevented from being clogged in the through hole 426 (material relay pipe).

Here, the first rotation speed is a speed at which the material M is not discharged from the relay member 420. The second rotational speed is a value at which the material M is discharged from the relay member 420 and transferred to the second container 120, and is a value larger than the first rotational speed. Note that the values of the first and second rotational speeds can be set by experiment.

Then, after a predetermined time (t9) has elapsed from the start of rotation of the filling device unit 400, processing for stopping the rotation of the filling device unit 400 is started.

  Here, the first rotation speed (w8) is a value at which the material M does not contact the through hole 426 in the relay member 420. Further, the second rotational speed (w9) is a value sufficient to transfer and fill the material M into the second container 120. The predetermined time (t8) is a time sufficient for the height of the material M contacting the inner peripheral surface 424 to be constant over the entire circumference of the relay member 420 (side surface 422), and the material M is It is a value that does not contact the through hole 30. Further, the predetermined time (t9) is a value sufficient to fill the second container 120 with the material M. Specific values of the first rotation speed (w8), the second rotation speed (w9), the predetermined time (t8), and the predetermined time (t9) can be derived by experiments.

  That is, in the present embodiment, in the step of filling the material M into the second container 120 (step S230), as shown in FIG. 36, the material M enters the through hole 426 in the relay member 420 for an initial predetermined time.

Contains. In addition, in FIG. 37, the mode of the material M at the time of a 1st step is shown typically.

(2) Effect In the present embodiment, after the variation in the height of the material M in contact with the inner peripheral surface 424 is reduced, the rotational speed of the relay member 420 is increased and the material M is filled in the second container 120. be able to. Therefore, the material M can be brought into contact with all the through holes 426 (substantially) at the same time, and the material M can be uniformly distributed to the plurality of second containers 120 with high accuracy.
