The tip portion of the nozzle portion 87 inserted by the convex portion 92 and the ceiling surface is supported, and is prevented from falling off. Further, the exhaust duct 84 protrudes from the lower surface of the nozzle guide 90.

Next, the operation of the medicine packaging machine will be described. Since the medicine packaging operation is the same as the conventional one, only the cleaning operation of the disk 8 will be referred to in the following description.

In other words, the brush cover 23 is positioned at the standby position while the powder stored in the annular groove 10 of the disk 8 is scraped by the scraping device 9. When all the powder in the annular groove 10 is scraped, the brush cover 23 is rotated and positioned at the cleaning position.

At this time, the axial center direction of the brush portion 22 coincides with the radial direction of the disk 8, and the tips of the wire portions 63 are in pressure contact with each other along the surface of the annular groove 10. Further, the tip edge portion of the scraping member 80 is also pressed in a state along the surface of the annular groove 10. Therefore, a suction mechanism (not shown) is driven to suck the inside of the brush cover 23 via the telescopic duct 41. Further, the brush motor 31 is driven to rotate the brush portion 22 via each gear. Further, the disk 8 is rotated, and the powder remaining in the annular groove 10 is scraped in the circumferential direction by the scraping member 80.

By the way, the rotation direction of the brush portion 22 is a clockwise direction when viewed from the center side of the disk 8 in the outer diameter direction, and coincides with the spiral direction of each wire portion 63 of the brush portion 22. Accordingly, the direction in which the powder remaining in the annular groove 10 is scraped and conveyed by the wire portions 63 coincides with the suction direction, and the powder is smoothly discharged to the suction mechanism side.

As described above, the powder remaining in the annular groove 10 of the disk 8 is scraped out, but the powder may remain in the cleaner device itself. Therefore, the cleaner device 18 is cleaned as follows.

That is, the upper surface cover 6a of the apparatus body 6 is opened and the cleaner device 18 is exposed. The cleaner device 18 is located in a relatively wide space where other parts on the left side are not close to the front of the device body 6. For this reason, it is excellent in workability and can be easily cleaned.

Subsequently, the main body cover 24 is opened, and the brush cover 23 is exposed. Then, the brush cover 23 is gripped and pushed into the telescopic duct 41 side. As a result, the duct main body 42 of the telescopic duct 41 is pushed into the opening 40 of the first bearing portion 26 against the biasing force of the coil spring 49, and the first shaft portion 67 of the brush cover 23 is moved to the second bearing portion. The first cylindrical portion 37 of the 27 falls off. As a result, the brush cover 23 and the brush part 22 can be removed from the cleaner body 21. Further, the brush portion 22 can be removed from the brush cover 23 by removing the brush driven gear 68 from the brush cover 23. Furthermore, the scraping member 80 can be easily removed from the brush cover 23 by simply pushing the locking projection 55 to deform the elastic piece 78 and sliding it downward.

  Further, the brush cover 23 and the brush part 22 removed from the cleaner body 21 can be attached to the cleaner body 21 as follows. That is, in a state where the brush portion 22 is assembled to the brush cover 23, the connecting cylinder portion 73 is inserted into the first duct portion 46 of the duct body 42 and pushed in against the urging force of the spring 49. Then, the brush cover 23 is moved in the axial direction, and the first shaft portion 67 having the second guide ring 72 is inserted into the through hole of the second bearing portion 27. The driven gear portion 75 for the cover and the second intermediate gear 71 for the brush are respectively positioned on the circumference centered on the axis of the brush cover 23. A portion of the brush cover intermediate gear 36 and the brush first intermediate gear 34 are exposed so as to be able to mesh with them. Therefore, as described above, simply by moving the brush cover 23 in the axial direction, the driven gear portion 75 for the cover becomes the intermediate gear 36 for the brush cover, and the second intermediate gear 71 for the brush becomes the first intermediate gear 34 for the brush. It can be engaged smoothly.

Thus, the brush cover 23 and the brush part 22 with which a powder medicine may adhere | attach can be easily removed from the cleaner main body 21, and both can be disassembled. In addition, the scraping member 80 can be easily removed from the brush cover 23. Therefore, these members can be easily cleaned. In cleaning the brush cover 23 and the brush portion 22, it is possible to wash them in a circle, and if they are deteriorated, it is possible to replace the parts (particularly, the brush portion 22 and the scraping member 80).

  In addition, the powdered powder scattered outside the disk 8 is sucked using the suction duct 83 as appropriate. As for the suction duct 83, the bellows-like hose 86 is easily damaged by use. Therefore, when the hose 86 is damaged, the screwed state with the nozzle portion 87 is released, and the hose 86 is removed from the nozzle guide 90, whereby only the hose 86 is removed and replaced. For this reason, since it is not necessary to replace the expensive nozzle part 86 compared with the hose 86, it becomes possible to respond | correspond at low cost.

In the embodiment, the pair of bearing portions (the first bearing portion 26 and the second bearing portion 27) that face the cleaner body 21 at a predetermined interval are formed. However, the bearing portion includes the expansion duct 41 and the like. A cantilever structure with only one side is also possible. In this case, the shaft main body 62 of the brush portion 22 may be rotatably supported by the bearing portion and may be configured to mesh with the intermediate gear (the second intermediate gear for brush 71) at that position. In addition, the bearing portion may be provided with a retaining mechanism that prevents the mounted brush cover 23 from falling off. According to this configuration, the cleaner device 18 can be configured to be even more compact.

In addition, the cleaner device 18 may have a cantilever structure that is rotatably supported on a single bearing portion as follows. That is, as shown in FIG. 22, a cylindrical portion 66 is formed on one end wall of the brush cover 23, and a flexible hose (not shown) is connected to the cylindrical portion 66. A cover driven gear portion 75 is integrally formed on one end wall of the brush cover 23, and the brush second intermediate gear 71 is rotatably attached coaxially with the cover driven gear portion 75. Yes. Further, a brush driven gear 68 integrated with the shaft member of the brush portion 22 is exposed at one end wall of the brush cover 23 and meshed with the brush second intermediate gear 71. In the same manner as in the above embodiment, the cover driven gear portion 75 is engaged with the brush cover drive gear 35 via the brush cover intermediate gear 36, and the drive force from the brush cover motor 32 is applied to the brush cover 23. To be communicated to. Further, the brush drive gear 33 is engaged with the brush second intermediate gear 71 via the brush first intermediate gear 34 so that the driving force from the brush motor 31 is transmitted to the brush portion 22. It has become. According to this configuration, a mechanism for driving the brush cover 23 and the brush part 22 can be provided regardless of the cylindrical part 66, and the workability and the assemblability are excellent.

Other embodiments are described below. As shown in FIG. 23 (a), the R disk 8 may have a flange portion 94 that is located outside the outer peripheral extending portion 11 and located below or above the outer extending portion 11. In place of the outer peripheral extending portion 11, when the inner peripheral extending portion is formed inside the annular groove 10, the flange portion 94 is also positioned inside. The collar portion 94 is supported by a support roller 93. When it has this collar part 94, the approach of the powdered medicine to the support roller 93 is reduced compared with the case where the outer peripheral extension part 11 is supported by the support roller 93. Therefore, there is no hindrance to the rotation operation of the R disk 8. In FIG. 23 (b), the brush cover 23 is extended to above the collar portion 94. Further, a scraping piece 82 that works to stop the powder spread of the outer peripheral extension portion 11 and the annular groove 10 on the downstream side in the rotation direction of the R disk 8 at the time of cleaning (downstream side from the brush portion 22), and above the flange portion 94. The formed scuffing piece 95 for the buttocks is shown. By this scraping piece 95 for the buttocks, the powdered medicine of the buttocks 94 can be reliably damped, and the powdered powder that has been damped can be sucked. Further, as another example of cleaning the flange portion 94, a passage for facilitating the suction of powder from the flange portion 94 to the telescopic duct 41 (suction portion) or from the flange portion 94 to the connecting cylinder portion 73 may be provided. Good. Note that the mounting plate 81 is omitted in FIG.
