Abstract

PURPOSE:To distribute a plurality of kinds of unmixed granules, so that the qualities of granules are made equal and the rate of components is specified. CONSTITUTION:Granules stored in a first storage vessel 110 are allowed to fall and scattered on a first granule scattering member 121 in a state wherein a first distribution vessel 122 is rotated at the specified velocity. The scattered granules are recovered in the first distribution vessel 122. The granules are allowed to fall on a second granule scattering member 151 through a second storage vessel 140 from the first distribution vessel 122 in a state wherein a second distribution vessel 152 is rotated at the specified velocity. The granules are recovered in the second distribution vessel 152. Therefore, since the first and second grain scattering members 121 or 151 scatter the granules random, the amount and component of granules recovered in the respective distribution vessels 122 and 152 are made uniform.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for distributing a plurality of types of granules in the same proportion and in equal amounts.

[0002]

2. Description of the Related Art Conventionally, in order to dispense a medicine prepared by mixing a plurality of types of granules (powder and granules, etc.), the mixture is once uniformly mixed in a V-type mixer or the like and then weighed in a predetermined amount The method of packing and packaging is adopted.

On the other hand, the applicant of the present invention has proposed a device for uniformly mixing and distributing a relatively small amount of granules, which was previously disclosed in Japanese Patent Application Laid-Open No. 4-235726. A conventional granule mixing and dispensing device for mixing and dispensing a relatively small amount of granules will be briefly described below. The conventional granule mixing / distributing device disclosed in Japanese Patent Laid-Open No. 4-235726 has a plurality of funnel-shaped mixing containers having a substantially V-shaped cross section in the vertical direction, and each mixing container has an opening at the bottom thereof. A shutter device is provided. Immediately below the lower part of the shutter device at the lowermost stage, a rotary table having a spherical granule scattering member fixed on a rotating shaft is provided, and a plurality of distribution containers are provided on the rotary table. Centered around, it is tightly connected and placed.

First, a plurality of types of granules to be mixed are put into the uppermost mixing container, and a shutter provided below the uppermost mixing container is opened. The granules fall so as to be sucked toward the center of the opening as observed with, for example, an hourglass. Therefore, even if a plurality of types of granules are not mixed at first, they are mixed to some extent when dropped into the lower mixing container. Furthermore, the granules that dropped into the lower mixing vessel create a mountain with a small summit just below the opening,
The granules falling from the top are scattered in a conical shape around the periphery, and the falling side is stopped at the inclined side surface of the mixing container. That is, when all the granules have fallen to the lower stage, the degree of mixing further increases. By repeating this operation a plurality of times, the granules are finally mixed fairly uniformly. Further, the granules dropped from the lowermost mixing container are made to collide with granule scattering means, for example, a fixed ball. The balls randomly scatter the granules downward in a cone. The granules that are randomly scattered in a downward conical shape are collected in a plurality of distribution containers that are rotating at a relatively high speed, so that the granules in each distribution container are distributed in a plurality of approximately equal amounts.

[0005]

The above-mentioned conventional granule mixing / dispensing device configured as described above is intended to be used when, for example, quality inspection of mass-produced granules, etc. A plurality of mixing containers were provided in the vertical direction so that not only the amount of each granule and the ratio of each component were uniform but also each kind of granule was uniformly mixed. But,
As for a drug or the like that is mass-produced in a factory or the like, a plurality of types of granules do not necessarily have to be uniformly mixed in each sachet as long as the contents and components of each sachet are constant. In addition, in actuality, an error within a predetermined range is allowed in the contents and the ratio of components in each package. Therefore, the conventional granule mixing and distributing apparatus as described above has a problem that it is not optimal for mass production as it is. The present invention has been made to solve the above problems, and is an improvement of the above-mentioned granule mixing / distributing device suitable for mass production.

After replacement, the first distribution container is rotated, and the granules collected in the next first distribution container are dropped into the second storage container. The above procedure is repeated until the redistribution of granules in all first dispensing containers is complete. On the other hand, in each of the inventions described in claims 2, 3 and 4, the granules collected in each of the first distribution containers are second

According to the invention described in claim 1, the first
Granules fall from the storage container of No. 1 to the first granule scattering means, collide with the first granule scattering means, are randomly scattered, and are collected in the first distribution container rotating at a constant speed. First, an equal amount and proportion of components are uniformly distributed to m pieces. Further, the granules distributed to one first distribution container are equally distributed to n pieces and the ratio of the components is uniform by the second storage container, the second granule scattering means and the second distribution container. It Therefore, in the end, it is possible to evenly distribute the same amount and the ratio of components to m × n. According to the invention described in claim 2, further, the granules, which are evenly distributed in the m first distribution containers in the same amount and the ratio of the components are uniform, and at the same time in the n granules, the same amount and the ratio of the components are uniform. And the time required for distribution can be shortened. According to the invention described in claim 3, since a plurality of types of granules can be stored in different storage tanks and can be sequentially charged into the first storage container for each type, the grain size can be extremely large. Even when a plurality of different types of granules are mixed, they can be distributed for each component, and there is no fear of causing segregation. According to the invention described in claim 4, since a plurality of sets of the unit comprising the second granule scattering means and the second distribution container are arranged on the same pallet, the pallets can be conveyed to the next step. Therefore, mass productivity is improved.
