  In the conventional powder scraping device, the powder adhering to the scraping surface can be cleaned, and the amount of powder supplied to the distribution tray is adjusted in consideration of the amount removed by cleaning in advance. Can be set to a desired amount of packaging.

  However, until now, when scraping the first packet from the dispensing tray, it has not been taken into account that the powder adheres to the surface opposite to the scraped surface (non-scratched surface) and is scraped together. It was. In addition, the fact that the amount of the final package is reduced by the amount adhering to the non-scratched surface has not been considered. In this case, it may be possible to adjust the feeding amount of the distribution tray in consideration of the adhesion of powder to the non-scratched surface, but the adhesion situation varies depending on the type of powder, so it is possible to handle all powders. Impossible. Furthermore, if the scraping width dimension of the scraping plate is smaller than the scraping width dimension of the scraping plate, before scraping out the powder, rotate the distribution tray in the reverse direction once to remove the final package medicine from the non-scratching surface. Therefore, the amount of powder adhering to the non-scratched surface increased, and the same error was generated.

  Then, this invention makes it a subject to provide the powder scraping apparatus and chemical | medical agent packaging apparatus which can prevent the dispersion | variation in the amount of packaging.

As a means for solving the above problems, the present invention provides:

Then, the medicine from the collection hopper 11 is packaged one by one by heat-sealing the three places.

  Next, the operation of the medicine packaging apparatus having the above configuration will be described.

  First, the powder in the annular groove 4 is separated by rotating the scraping unit 3 and bringing the scraping plate 12 into pressure contact with the annular groove 4 while the powder is evenly supplied to the annular groove 4 of the distribution tray 5. . Since the elastic edge portion 16 made of silicon is integrated with the outer peripheral edge of the scraping plate 12, the powder in the annular groove 4 can be appropriately separated without damaging the distribution tray 5.

  Subsequently, after rotating the distribution tray 5 by a predetermined angle, the scraping plate 12 and the scraping plate 13 are rotated once. As a result, the powdered drug scraped by the scraping plate 12 is separated by one package by the scraping portion 19 of the scraping plate 13, scraped out from the distribution tray 5 by the scraping portion 19, and then packed by the packaging device 3. Packaged.

  In the same manner, each time the distribution tray 5 is rotated by a predetermined pitch, the scraping plate 12 and the scraping plate 13 are rotated once, so that the packaging device 3 packages one package.

  By the way, the powdered medicine that has adhered to the scraping surface 12a of the scraping plate 12 and has not been packaged is cleaned by the screw brush 16 after the series of scraping operations are completed and the scraping member 10 is moved to the standby position. The On the other hand, when packaging the first package, when the powder in the annular groove 4 is divided and scraped by the scratching plate 12, the powder adheres to the non-scratched surface 12b of the scratching plate 12. This non-scratched surface The powder adhering to 12b is scraped off into the annular groove 4 when the scraping edge 31a of the elastic piece 31 of the dust-preventing member comes into sliding contact. Therefore, it is possible to prevent a problem that the amount is reduced by the amount of the powder adhering to the non-scratched surface 12b of the scraping plate 12 in the final package. Further, the scraping member 25 can be removed from the holding portion 24 and easily exchanged for a new one if the scraping edge 31a of the elastic piece 31 is worn due to long-term use.

  In addition, this invention is not limited to the structure described in the said embodiment, A various change is possible.

  For example, the scraping member 25 is detachable from the arm member 14, but may be detachable from another member (for example, a portion that supports the distribution tray 5). Further, it is not detachable but can be fixed.

  Further, the scraping plate 13 is integrated with the scraping plate 12, but it may be driven separately as a separate body.
