DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

2. Description of the Related Art Conventionally, in order to dispense a medicine obtained by mixing a plurality of types of granules (powder and granules, etc.), they are once uniformly mixed with a V-type mixer or the like and then weighed at predetermined amounts. The method of 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 as disclosed in Japanese Patent Application Laid-Open No. Hei 4-235726. A conventional granule mixing and dispensing apparatus for mixing and dispensing a relatively small amount of granules will be briefly described below. The conventional granule mixing and dispensing apparatus disclosed in Japanese Patent Application Laid-Open No. 4-235726 is provided with a plurality of funnel-shaped mixing containers having a substantially V-shaped cross section in a vertical direction, and provided at each lower opening of each mixing container. A shutter device is provided. Immediately below the lower part of the lowermost shutter device, there is provided a rotary table having a spherical particle scattering member fixed on a rotation axis, and on this rotary table, a plurality of distribution containers are provided with a particle scattering member. And are mounted without any gaps.

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

[0005]

The above-mentioned conventional granule mixing and dispensing apparatus constructed as described above is intended to be used, for example, when inspecting the quality of mass-produced granules and the like. A plurality of mixing containers are provided in the vertical direction so that not only the amount of each granule and the ratio of each component are uniform, but also each type of granule is uniformly mixed. But,
In the case of a drug or the like mass-produced in a factory or the like, it is not always necessary that a plurality of types of granules are uniformly mixed in each package as long as the content and components of each package are constant. Further, in practice, an error within a predetermined range is allowed for the content of each package and the ratio of components. Therefore, the conventional granule mixing and distributing apparatus has a problem that it is not an optimum configuration for mass production as it is. The present invention has been made to solve the above problems, and is an improvement of the granule mixing and distributing apparatus so as to be suitable for mass production.

The amounts of the granules collected in 1-1 to n are substantially equal, and the ratio of the granules for each type is also substantially constant. When the redistribution of the granules collected in one first distribution container to the second distribution container is completed, the second distribution container is replaced with a new one, and the first distribution container is rotated. Next, the granules collected in the first distribution container are dropped into the second storage container 40 . The above procedure is repeated until the redistribution of the granules in all the first distribution containers is completed.

According to the invention described in claim 3, a plurality of types of granules can be stored in different storage tanks, and can be put into the first storage container for each type in order, so that the size of the granules is extremely small. Even when a plurality of different types of granules are mixed, they can be distributed for each component, and there is no fear of segregation. According to the fourth aspect of the present invention, a plurality of units each including the second granule scattering means and the second distribution container are arranged on the same pallet, so that the pallet can be transported to the next step. And mass productivity is improved.
