Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a capacity dividing method and a dividing device for dividing a drug such as powdered medicine into predetermined amounts.

[0002]

2. Description of the Related Art FIG. 14 shows a conventional drug volume dividing device. In this device, an annular groove 5 (or a flat surface) having an arc-shaped cross section is formed on the outer periphery of the upper surface of the distribution disk 1 supported by the rotation drive mechanism 70, and the medicine is supplied to the outside of the distribution disk 1. The means 2 and the rotary plate type medicine scraping means 3 for scraping the chemicals accumulated in the annular groove 5 to the outside are arranged.

In the above apparatus, the drug is supplied from the supply means 2 while the distribution disk 1 is rotated at a constant speed, and the annular groove 5 is supplied.
Then, while the distribution disc 1 is rotated at a constant speed, the accumulated drug is scraped out by the drug scraping means 3, and the drug is divided and taken out from the annular groove 5 quantitatively.

[0004]

In order to improve the work efficiency in the dividing device having the above-mentioned structure, the time required for supplying and depositing the drug by increasing the speed of supplying the drug to the distribution disk 1 and depositing it on the annular groove 5. Should be as short as possible.

However, when the rotation speed of the distribution disk 1 at the time of drug supply is increased in order to shorten the drug supply and deposition time,
Since the annular groove 5 on which the drug is accumulated is a shallow arc-shaped groove,
Due to the centrifugal force of the rotation, the medicine is scattered from the distribution disk 1 and there is a problem that the volume division cannot be performed reliably.

On the other hand, the scattering of the above-mentioned chemicals is shown in FIG.
As shown by the chain line, the wall surface 5a on the outer peripheral side of the annular groove 5 can be raised to some extent, which can be dealt with to some extent. However, such an upright wall surface 5a has a large scraping action by the drug scraping means 3. There are obstacles.

Therefore, the setting range of the rotation speed of the conventional distribution disk 1 is restricted to a certain narrow range,
There was a problem that it could not be expected to improve work efficiency sufficiently.

In view of the above, the present invention solves the above-mentioned problems, enables the speed-up rotation of the distribution disk at the time of supplying and depositing the medicine to improve the work efficiency, and enables the scraping operation of the medicine by the scraping means to be performed without any trouble. It is an object of the present invention to provide a capacity dividing device capable of performing stable drug division.

[0009]

In order to solve the above-mentioned problems, the invention of the first method is such that a cover disk having an openable / closable cutting portion is superposed on a distribution disk, and distribution is performed with the cutting portion closed. After rotating the disc and cover disc together to supply and evenly deposit the drug in the annular groove of the distribution disc, the cover disc is decelerated and the excision is opened during rotation until the drug is not scattered. The distribution disc is rotated to a position where the excision part coincides with the scraping means and stopped, and in this state the distribution disc and the cover disc are separated from each other, and then the distribution disc is rotated to open the excision part in the annular groove. The drug was scraped out by a scraping means.

[0010] The invention of the second method, the release opening of the cutout of the first aspect of the present invention, cutout distribution disc instead during rotation of the distribution disc is stopped at a position coinciding with opening and closing means I did <br/> to do it.

Further, in the invention of the third method, after the cutting portion is opened, the distribution disk and the cover disk are separated from each other, and the cover disk is rotated to a position where the cutting portion coincides with the scraping means and stopped. Of.

Further, in the invention of the fourth method, after supplying and uniformly depositing the drug in the annular groove of the distribution disk, the distribution disk and the cover disk are separated from each other, and the position of the cut portion of the cover disk is opened and closed. Stop at the position that coincides with the means to open the resection,
Then, the cover disk was rotated to a position where the excised portion coincides with the scraping means and stopped.

In order to solve the above problems, the invention of this device is to provide a distribution disk and a ring-shaped cover disk overlapping with the upper surface of the distribution disk so that they can approach and separate from each other, and the cover disk can be opened and closed. A part is provided, and opening / closing means for opening / closing the excised part is arranged above the outer periphery of the cover disc.The cover disc is opened by the opening / closing means and stopped when the excision part coincides with the scraping means. I decided to do it.

Further, in the invention of the second device, the opening / closing means for opening / closing the cut portion is arranged on the upper surface of the cover disk.

[0015]

In the dividing device having the above structure, the upper surface of the distribution disk is covered with the cover disk with the cut portion closed, and in this state, the drug is supplied from the upper part of the cover disk to the distribution disk while rotating the distribution disk together with the cover disk at high speed. By doing so, since the cover disc overlaps the upper surface of the distribution disc, it is possible to prevent the drug from scattering due to centrifugal force, and it is possible to efficiently and uniformly deposit the drug on the distribution disc.

Further, the cutting portion is opened during the rotation of the cover disc, or the cutting portion of the rotating cover disc is stopped and opened at a position corresponding to the opening / closing means, and the cutting portion is brought to a position corresponding to the scraping means. By stopping the operation, the operation of scraping out the medicine on the distribution disk by the scraping means can be performed without any trouble in the opened resection part.
