(5a, 5b) are arranged facing each other. The feeder 4 (4a, 4b) is provided with a stopper 6 (6a, 6b) for blocking the powder.

  A support arm 7 is disposed above the rotary table 2 so as to straddle the rotary table 2, and a scraping blade 9 attached to the rotary shaft 8 supported by the same axis at the tip of the support arm 7, A circular partition plate 10 that is attached to a boss that is fitted to the rotary shaft 8 via a bearing is provided, and a cleaning head 11 for cleaning the powder receiving groove 3 is provided in a direction opposite to the tip of the support arm 7. Is provided. A solid agent divided supply unit 12 including 48 divided masses 13 is provided so as to cross the upper side of the turntable 2. The bottom plate 14 of the divided mass 13 is intermittently opened sequentially on a chute 15 provided on the lower side of the solid agent divided supply unit 12 so that the solid agent in the divided mass is packaged through the chute 15. It has become.

  A hopper 16 is provided on the lower side of the scraping blade 9, and the powder on the powder receiving groove 3 or the solid agent dropped on the chute 15 passes through the hopper 16 in the packaging part 17 disposed below the hopper 16. It is configured to be packaged one by one.

  A front view and a side view of the feeder 4 are shown in FIGS. 3 (a) and 3 (b), respectively. A circular cam 18 for operating the stopper 6 provided in the feeder 4 in the vertical direction is provided on a side surface of the feeder 4. The cam 18 is connected to a motor 20 via a cam rotation shaft 19. ing. Since the cam rotation shaft 19 is connected to the eccentric position of the cam 18, the stopper 6 can be operated in the vertical direction by the cam 18 rotating about the cam rotation shaft 19.

  In this embodiment, for example, when two types of powders are packaged as a mixed medicine, the powders of the feeders 4a and 4b are simultaneously received while the rotary table 2 is rotated while supplying the powders one by one to the two feeders 4a and 4b. Supply to groove 3. Next, the powder that is mixed on the powder receiving groove 3 is divided by the circular partition plate 10 one by one, and the mixed medicine of this one quantity rotates the scraping blade 9 around the rotary shaft 8 to rotate the hopper 16. To be supplied. This one pack of mixed medicine is packaged through the hopper 16.

  Therefore, it is not necessary to prepare the mixed medicine in advance when the mixed medicine is packaged, and it is not necessary to fear separation due to the difference in specific gravity of the mixed medicine that occurs when the pre-made mixed medicine is supplied to the powder receiving groove 3. . Moreover, since two types of powder can be simultaneously supplied to the powder receiving groove 3, the powder supply time can be shortened.

  In this embodiment, for example, when two types of powders are packaged one by one, the powder to be packaged first is supplied to the first feeder 4a (or the second feeder 4b), and the rotary table 2 is rotated while rotating. The powder of 1 feeder 4a is uniformly supplied to the powder receiving groove 3. While the powder to be packaged first is being supplied to the powder receiving groove 3, the powder to be packaged later is supplied to the remaining second feeder 4b, and the powder is dammed by the stopper 6b and placed on the rotary table 2. The powder of the second feeder 4b is prevented from spilling out. After the powder to be packaged first is supplied onto the powder receiving groove 3, the powder on the powder receiving groove 3 is partitioned by the circular partition plate 10, and the scraping blade 9 rotates around the rotation shaft 8. Is supplied to the hopper 16. This powder is packaged through the hopper 16.

Is. Therefore, the length of the solid agent divided supply section can be reduced without reducing the number of divided masses and the number of solid agents that can be stored in the divided mass, and the apparatus has only one rotary table 2. The whole can be considerably downsized.

  In this embodiment, the combination of a powder and a solid agent can be set arbitrarily. For example, when the powder and the solid agent are alternately packaged one by one, the powder is supplied to the powder receiving groove 3 and the amount of the solid agent is supplied to the divided mass 13. Thereafter, the powder in the powder receiving groove 3 rotates the scraping blade 9 about the rotation shaft 8, whereby a one-packed amount of powder is supplied to the hopper 16 and then packed, and then the bottom plate 14 of the divided mass 13. Is opened, and a 1-pack quantity of solid agent is supplied to the hopper 16 through the chute 15 and packaged. Thus, by changing the packaging order of the powder supply and the solid powder supply, the combination of the powder and the solid agent can be changed according to one dose. Moreover, it is also possible to make a powder and a solid agent into one package.

  In the present embodiment, the number of divided masses 13 is 48. However, the number is not limited to 48 and may be more or less, but about 48 is suitable for practical use.
