  Hereinafter, an embodiment of the present invention will be described with reference to FIGS. FIG. 1 and FIG. 2 are an overall plan view and a partially broken front view showing a distribution device 1 of the present embodiment. FIG. 3 is an enlarged view showing the leveler 11 of the present embodiment. 4 and 5 are enlarged views showing the filling nozzle 40 and the comb-shaped blades 13a and 13b of this embodiment, and FIG. 6 is a cross-sectional view taken along line AA in FIG. 7 and 8 are enlarged views showing a filling state and a distribution state by the filling nozzle 40. FIG.

  As shown in FIGS. 1 to 2, the distribution device 1 is provided facing a conveying means 6 such as a belt conveyor that intermittently conveys a blister pack 3 as a container in a certain direction. The blister pack 3 has a sheet shape in which a large number of holes 4 are recessed, and is placed on the conveying means 6 while being fitted to the conveying plate 7. The distribution device 1 is used to distribute the granular material P into the hole 4 of the blister pack 3 by a certain amount.

  Examples of the “powder and granule” include various powders and granules such as pharmaceuticals, cosmetics, and foods, or a mixture thereof. Further, in this embodiment, the blister pack 3 is used. However, the “container” may be any one having a hole (regardless of size or number of arrangements) capable of storing a certain amount of powder particles. . That is, in addition to capsules, concave injection plastics, and the like, glass bottles can also be used as containers.

  The distribution device 1 will be specifically described. As shown in FIGS. 1 to 2, the distribution device 1 mainly includes a rotating tray 10, a leveler 11, a filling unit 12, comb blades 13 a and 13 b, and a supply unit 14. In the figure, reference numeral 8 denotes a gantry for supporting the distributor 1 in a horizontal state.

  As shown in FIGS. 1 to 2, the rotating tray 10 has a slightly flat bottomed cylindrical shape as a whole. The outer wall surface 21 and the inner wall surface 22 that are erected in a shape form a housing portion 23 that is continuous in the circumferential direction with a U-shaped cross section that is open at the top. The accommodating part 23 accommodates the granular material P. The rotating tray 10 may have a bottomed cylindrical shape without providing the inner wall surface 22.

A shaft 25 connected to a motor (not shown) or the like is suspended from the center of the rotating tray 10 so that the rotating tray 10 and the shaft 25 can be integrally rotated in the rotation direction R around the axis X. It is configured. Between the gantry 8 and the rotating tray 10, a roller 10a for rolling and supporting the rotating tray 10 from below is provided at an appropriate position (see FIG. 2).
On the rotating tray 10, a leveler 11, a filling unit 12, comb blades 13 a and 13 b, and a supply unit 14, which will be described in detail below, are sequentially arranged along the rotation direction R at appropriate intervals. It is arranged without following the rotation.

As shown in FIGS. 1 and 3, the leveler 11 includes a standing portion 30 and an extending portion 31, and is fixed by fixing means 33 provided at appropriate positions on the gantry 8. The standing portion 30 is provided so as to be opposed to the powder P in the accommodating portion 23 that is rotated with a broken line 35 that coincides with the radial direction of the rotating tray 10 as a base line. , opposing surface 36 which forms a predetermined angle is formed relative to the surface P _S to be formed of the particulate material P as shown in FIG.

  Further, an extension part 31 is extended in front of the upright part 30 in the rotation direction R via a broken line 35. As shown in FIG. 1, the extending portion 31 has a wide arch shape in plan view, faces the outer wall surface 21 and the inner wall surface 22 of the rotating tray 10, and has an outer arc 38 and an inner arc 39 that form the same central angle α. Is provided. As shown in FIG. 3, a horizontal contact surface 37 that is continuous from the facing surface 36 via a broken line 35 is formed at the lower end of the extending portion 31.

As is apparent from FIG. 3, the standing part 30 of the leveler 11 is smoothed out irregularities of the granule P accommodated in the accommodating portion 23, to form a smooth surface P _S in the rotation direction R forward In addition, it serves to deposit excess powder P, but the powder P is maintained at a predetermined thickness d by the extending portion 31 for a certain period of time. The air in the granular material P is appropriately deaerated. Thereby, the granular material P is compressed to a predetermined density, and the density of the granular material P is made uniform.

  A constant inertial force (centrifugal force) or the like acting radially outward from the axis X is acting on the powder P in the accommodating portion 23 as the rotating tray 10 rotates. For this reason, in particular, while the granular material P collides with the standing portion 30 of the leveler 11 and is in contact with the extending portion 31, the granular material P easily spreads radially outward in the accommodating portion 23. Since the extending portion 31 is configured in the above-described predetermined wide-view shape having a wide arcuate shape, the density of the powder particles P can be made very effectively uniform.

  Needless to say, the central angle α of the extending portion 31 can be appropriately set to an optimal value according to the type, composition, shape, physical properties, etc. of the granular material P. However, if the center angle α is too small, it is difficult to obtain the effect of degassing. On the other hand, if the center angle α is too large, the fluidity of the powder P may be inhibited and a bridging phenomenon may occur. There is. Therefore, generally, about 10 ° ≦ α ≦ 50 ° is preferable, and more preferably 20 ° ≦ α ≦ 40 °.

  As shown in FIGS. 1 to 2, the filling unit 12 is disposed on the downstream side of the leveler 11, that is, in front of the rotation direction R of the leveler 11. The filling unit 12 is formed by aligning a plurality of filling nozzles 40 in a predetermined state corresponding to the hole 4 of the blister pack 3. The filling nozzle 40 is inserted and fixed to a fixed plate 41, and the fixed plate 41 is further fitted on a predetermined moving means 43.

  The moving means 43 allows the filling unit 12 to move up and down on the rotating tray 10 and reciprocate between the rotating tray 10 and the container 3 on the conveying means 6. In this embodiment, the moving means 43 includes a cylinder 44 formed so as to be vertically movable at an appropriate position on the gantry 8 and a slide bar 45 disposed so as to be horizontally movable above the cylinder 44. Both ends of the slide plate 47 into which the fixed plate 41 is fitted are fixed on the slide bar 45. The moving means 43 is appropriately connected to a cam mechanism, limit switch, etc. (not shown).

As shown in FIG. 4, the filling nozzle 40 includes a tubular housing 50 and a piston 52 provided along an axial air passage 51 in the housing 50. A locking ring 54 for locking to the upper edge of the insertion hole 41 a of the fixing plate 41 is provided at an appropriate position of the housing 50 so as to protrude outward. At the tip of the piston 52, a head 57 is formed which is in sliding contact with the inner peripheral wall 56 of the tip portion 55 of the housing 50 and has a horizontal pressure surface 57a. The chamber 59 is recessed. The distal end portion 55 of the housing 50 is formed in a sharpened shape that gradually becomes thinner toward the distal end edge 55a so that the insertion into the granular material P can be easily performed.
The cross-sectional shape of the housing 50, the piston 52, or the filling chamber 59 is not limited to a circular shape, and various types may be used. The amount of the granular material P that can be filled in the filling chamber 59 can be set to about 50 mg to 2500 mg depending on the size of the hole 4 of the container 3 and the type, composition, shape, physical properties, etc. of the granular material P.

  The filling nozzle 40 has a structure in which the capacity of the filling chamber 59 is changed by moving the piston 52 up and down, thereby compressing and filling a certain amount of powder P into the filling chamber 59. Is known.

  That is, the filling nozzle 40 incorporates a coil spring (not shown), and an operation rod 61 for operating and moving the piston 52 in the axial direction is connected to the top of the piston 52 as shown in FIG. As illustrated in FIG. 4, the piston 52 is moved up and down by the pressing means 63 including a pressing plate 64 having a pressing protrusion 65 corresponding to the operation rod 61 and operated by hydraulic pressure or air / gas pressure. It is possible to stop and hold at a predetermined position (the pressing means 63 is not shown in FIGS. 1 and 2).

  In this embodiment, the powder P is compressed and filled into the filling chamber 59 via the piston 52, but this does not exclude the adoption of another form of the filling nozzle 40. For example, the filling chamber 59 is fixed by preliminarily fixing the capacity of the filling chamber 59 with respect to the thickness (d) of the granular material P in the accommodating portion 23 and simply inserting the filling nozzle 40 downward into the granular material P. A certain amount of the granular material P may be pushed into 59. Further, the filling nozzle 40 may be connected to an appropriate suction unit so that the powder P is sucked and filled into the filling chamber 59. This configuration is particularly effective when the granular material P has a large particle size such as a granule.

As shown in FIG. 1, the comb blades 13 a and 13 b are disposed on the downstream side of the filling unit 12, that is, in front of the filling unit 12 in the rotation direction R. The comb blades 13 a and 13 b are fixed by fixing means 70 provided at appropriate positions on the gantry 8.
As shown in FIGS. 5 to 6, the comb blades 13 a and 13 b are provided so as to cross between the outer wall surface 21 and the inner wall surface 22 of the rotating tray 10. The comb-shaped blades 13a and 13b have the same shape, and a plurality of claw portions 72 that can scrape the granular material P in the accommodating portion 23 after being filled with the granular material P by the filling nozzle 40 of the filling unit 12 respectively. Have. The nail | claw part 72 is arrange | positioned so that the granular material P may be pierced from upper direction, and the front-end | tip may be located in the bottom surface 20 margin.

  As shown in FIG. 5, the comb blades 13 a and 13 b are opposed so that an intersection 73 formed by extending each of the comb blades 13 a and 13 b does not coincide with the axis X of the rotating tray 10. In such a configuration, the comb-shaped blades 13a and 13b having the same shape are simply arranged in the radial direction (the intersection and the axis X coincide with each other) as shown in FIG. The claw part locus 75a and the claw part locus 75b of the comb-shaped blade 13b are easily formed densely at different positions, and the granular material P in the housing part 23 can be evenly divided. Further, since the comb blades 13a and 13b have the same shape, the manufacturing cost and the like can be suppressed.

The interval 77 (see FIG. 6) of the claw portion 72 depends on the arrangement of the comb plates 13a and 13b, the size of the rotating tray 10, the diameter of the filling nozzle 40, the type, composition, shape, physical properties, etc. of the granular material P. May be changed as appropriate. The nail | claw part 72 can also be formed in a thin rod shape other than what was shown in FIG. Such a configuration is particularly effective when the granular material P has a large particle diameter such as a granule.
The comb-shaped blades 13a and 13b are not limited to a linear shape, and may be a curved shape such as a wave shape, a V shape, a zigzag shape, or the like. Further, only one comb blade or three or more comb blades may be provided.

As shown in FIGS. 1 to 2, the supply unit 14 includes a hopper 80, a chute 81, and a sensor 82. The supply unit 14 is downstream of the comb blades 13a and 13b and upstream of the leveler 11, that is, the comb blades 13a and 13b. Are arranged in front of the rotational direction R and rearward in the rotational direction R of the leveler 11.
The hopper 80 stores the granular material P outside the rotating tray 10, and can supply the granular material P toward the accommodating portion 23 of the rotating tray 10 through a chute 81 appropriately connected to the bottom. It has become. In FIG. 2, 81a is a vibrator for disperse | distributing the granular material P moderately.

  The sensor 82 is fixed at an appropriate position on the gantry 8 via fixing means 84. The sensor 82 senses the amount of the granular material P that passes through. In this embodiment, a sensor 82 that detects the displacement of the granular material P by static electricity is used. The hopper 80 is provided with a propeller fin (not shown) linked to the sensing of the sensor 82, and is controlled so that an appropriate amount of the granular material P can be forcibly discharged from the hopper 80 to the chute 81 when necessary. Has been.

Next, the usage mode etc. of the distribution apparatus 1 comprised as mentioned above are demonstrated.
First, as a preparation stage, a predetermined amount of the granular material P is supplied from the hopper 80 to the accommodating portion 23 of the rotating tray 10. Then, while a few turns of the carousel 10 in the rotation direction R, as shown in FIG. 3, the leveler 11, to form a smooth surface P _S to powder particles P, the density of the granular material P uniformly Keep it. Therefore, somewhat larger amount of the particulate material P than the surface P _S levels to be formed, is supplied to the accommodating portion 23.

  After passing through the preparatory stage, the filling unit 12 is moved downward, and the tip 55 of each filling nozzle 40 is lowered and inserted into the granular material P in the accommodating portion 23, so that the powder as shown in FIG. The granules P are pushed into the filling chamber 59. Then, as shown in FIG. 7B, the head 57 in the filling nozzle 40 is pressed and slid in a direction to reduce the capacity of the filling chamber 59, so that the powder P in the filling chamber 59 has a predetermined bulk density. Compress until This compression is performed in order to prevent the granular material P from falling off during the movement of the filling nozzle 40. Further, when the filling unit 12 is moved upward and the respective filling nozzles 40 are pulled up, a certain amount of the granular material P is compressed and filled in the filling chamber 59 as shown in FIG. At this time, a scraper or the like that neatly cleans the lower end of the filled powder P may be provided. During the filling operation, it is preferable that the rotation of the rotating tray 10 is temporarily stopped.

As described above, the filling unit 12 that has completed the filling of the granular material P into the filling nozzles 40 is moved above the conveying means 6. As shown in FIG. 8A, the blister pack 3 stands by on the conveying means 6 so that each hole 4 is positioned corresponding to each filling nozzle 40 of the filling unit 12, as shown in FIG. As shown, the granular material P in each filling chamber 59 is discharged into each hole 4 of the blister pack 3. This discharge is performed, for example, when the head 57 of the piston 52 moves to the vicinity of the edge of the front end portion 55 of the housing 50.
The filling unit 12 that has finished the discharge operation is returned to the rotating tray 10 again, and the above-described filling operation and the discharge operation are repeated.

  In the case where the powder P is sucked and filled into the filling chamber 59 of the filling nozzle 40, the powder P may be discharged by releasing the suction. Further, the filling chamber 59 may be cleaned by connecting an appropriate compressed air ejection means to the filling nozzle 40 and ejecting compressed air into the filling chamber 59 after discharge. Thereby, even if the powder P remains in the filling chamber 59, it can be reliably removed and the next metering and filling can be performed accurately.

  After the filling operation, a plurality of extraction holes 90 as shown in FIG. 7 (c) are formed in the granular material P in the accommodating portion 23. The extraction holes 90 are formed by comb blades 13a and 13b. Destroyed. This is because the pair of comb-shaped blades 13a and 13b having a predetermined configuration as described above effectively scrapes the granular material P in which the extraction holes 90 are formed as the rotating tray 10 rotates.

  By going through the filling operation or the like, the extraction hole 90 may be formed, or the powder P may be partially compressed and the density in the powder P may be non-uniform. By 13b, the extraction hole 90 of the granular material P can be destroyed, or the compressed portion can be loosened and softened.

The granular material P that has passed through the comb blades 13a and 13b is further rotated toward the leveler 11. At this time, the sensor 82 of the supply unit 14 senses the amount of the granular material P in the storage unit 23 and is insufficient. In this case, an appropriate amount of powder P is replenished and supplied via the hopper 80. Then, the leveler 11, together with the smooth surface P _S anew particulate material P is formed, it becomes possible density and homogenized particulate material P is subjected to the filling unit 12, the comb blade 13a and With the interaction between 13b and the subsequent leveler 11, the density of the powder P is very easily made uniform.

According to the distribution apparatus 1 described above, the leveler 11 and the comb blades 13a and 13b to form a predetermined configuration, with smooth surface P _S is formed on the particulate material P in the container portion 23, the granular material P The density of the powder P can be made uniform and can be continuously provided to each of the filling nozzles 40 of the filling unit 12. Therefore, a certain amount of the powder P to be distributed by the filling nozzle 40 can be easily maintained. Further, in combination with the configuration provided with the predetermined supply unit 14, it is possible to efficiently distribute the granular material P without interrupting the work one by one.

  In addition, the bottom surface 20 of the rotating tray 10 has a predetermined amount due to particles or the like of the powder fluid P interposed between the front end portion 55 of the filling nozzle 40 or the front end portion 55 when the powder P is filled into the filling nozzle 40. However, according to the distribution device 1, the lowering position of the filling nozzle 40 on the bottom surface 20 of the rotating tray 10 can be made different every time. Therefore, since the pressure and wear that can occur on the bottom surface 20 of the rotating tray 10 can be dispersed, the durability of the member can be improved.

  A modification of the above embodiment will be described with reference to FIGS. 9 (a), 9 (b), and 9 (c). FIGS. 9A, 9B, and 9C show levelers 11a, 11b, and 11c, which are other forms of the leveler 11, respectively. About the structure which is common in the said embodiment, the same code | symbol is attached | subjected and description is abbreviate | omitted.

As shown to Fig.9 (a), the leveler 11a can be comprised only by the standing part 30a. Facing surface 36a of the upright portion 30a is angled theta ₁ with respect to the surface _{P S.} The angle θ ₁ may be set to an arbitrary value satisfying 0 ° <θ ₁ <180 °, but in particular, when 0 ° <θ ₁ <90 °, the powder P has a constant compressive force from above. Therefore, it can be said that it is preferable from the viewpoint of uniform density of the powder P.

As shown in FIG. 9 (b), the upright portion 30b can be bent in two stages by a first upright portion 30b ′ and a second upright portion 30b ″. facing surface 36b ', the angle _{θ 2 (0 ° <θ 2} <90 °) without a relative surface _{P S,} "facing surface 36b of the" second upright portion 30b, the angle theta ₃ relative to the surface _{P S} In addition, the angle θ ₃ is a gentler angle than the angle θ _2. According to such a configuration, the collision force of the powder P against the upright portion 30b can be gradually reduced, and the powder The rotational movement and the like of P become smooth, and the density of the granular material P can be easily made uniform.

  As shown in FIG. 9 (c), the upright portion 30c is formed by the first upright portion 30b ′ and the second upright portion 30b ″, and the extending portion 31 is attached to the second upright portion 30b ″. It can also be set as the structure which interposed 2nd standing part 30b '' between 1 standing 30b 'and the extension part 31. According to such a structure, in the granular material P by the extension part 31 Since air can be deaerated appropriately, it is possible to make the density of the powder P more uniform.

  The leveler 11 and the levelers 11a, 11b, and 11c described above can be appropriately selected and used according to the type, composition, shape, physical properties, and the like of the granular material P.
