And 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 chemicals as described above can be dealt with to some extent by raising the outer peripheral wall surface 5a of the annular groove 5 upward, as shown by the chain line in FIG. The erected wall surface 5a has a problem that it greatly obstructs the scraping operation by the drug scraping means 3.

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.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to solve the above-mentioned problems and to provide a capacity dividing device capable of increasing the speed of rotation of a distribution disk at the time of supplying and accumulating a medicine and performing stable medicine division. .
