Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mixer used for mixing powders, granules, etc., which are raw materials for pharmaceuticals, foods, chemical kilns, etc. The present invention relates to a mixing machine.

[0002]

2. Description of the Related Art Conventionally, mixers used for mixing powders or granules, which are raw materials for medicines and foods, have been
It is proposed that the mixing container rotates and revolves. For example, the mixers described in Japanese Utility Model Publication No. 61-27618 and Japanese Utility Model Publication No. 61-27620 are configured such that a rotating cage rotates (revolves) and is supported in the rotating cage. The mixing container rotates (rotates)
The powder and the like put into the mixing container are efficiently mixed by the revolving rotation and the rotation by these structures. Particularly, in Japanese Utility Model Publication No. 61-27620, the stirring rod is statically attached to the inside of the mixing container, and the powder or the like in the mixing container is rotated by its own weight with the revolution and rotation of the mixing container. By colliding with the stirring blade, more efficient mixing can be performed.

[0003]

However, in these conventional mixers, the shaft around which the rotating cage rotates and the shaft around which the mixing container rotates are configured to rotate together. (Spinning) has a structure in which the rotational driving force of the drive motor is rotationally driven through the pulley 10 to rotate the small bevel gear, and the small bevel gear is rotated, so that the meshing sound of the small bevel gear is large. Further, when the powder or the like to be mixed enters the small bevel gear, the powder or the like becomes black foreign matter and often mixes with the powder or the like to be mixed. Further, as described above, in the conventional mixer, the rotation of the rotating cage and the rotation of the mixing container are made to rotate together, so that the configuration is extremely complicated and it takes time to manufacture and the cost is high. I have no choice. Also, the actual public 6
The mixer described in 1-27620 has basically the same configuration as that of JP-B-61-27618, and therefore has the same problem as the above problem. As described above, since the stirring rod is statically attached inside the mixing container as described above, the powder or the like put into the mixing container is not supported by the weight of the powder or the like due to rotation of the rotating cage or the mixing container. Since it collides with the stirring rod, it may not always be possible to sufficiently mix it depending on the type and amount of powder or the like to be mixed. Furthermore, in the above-described conventional mixer, since the shaft around which the rotating cage rotates and the shaft around which the mixing container rotates rotate together, the shape of the mixing container is extremely limited.
Therefore, the present invention has been proposed in order to solve the problems that the above-described conventional mixer has, and while maintaining high mixing efficiency, it can be made inexpensive with an extremely simple configuration, and noise of To provide a mixer which can reduce the generation of the powder and can effectively prevent the risk of foreign matter being mixed in the powder or the like to be mixed, and the shape of the mixing container is not limited to a specific shape. The purpose is. A further object of the present invention is to provide a mixer that achieves even higher mixing efficiency than conventional mixers.

Drive motor, a mixing container rotatably supported via a shaft portion formed at one end side in the rotation cage, and a lid attached to the other end, and the rotation cage. And a second drive motor that is fixed to and that rotates the mixing container.
In a second aspect of the invention, a stirring blade fixed to the tip side of a rotating shaft that is inserted into the shaft portion is provided on one end side in the mixing container, and the stirring blade is the rotating cage. It is characterized in that it can be rotated by a third drive motor fixed to.

[0005]

According to the mixer of the present invention, the rotation of the rotating cage (revolution of the mixing container) is fixed by the first drive motor, and the rotation of the mixing container (rotation) is fixed to the rotating cage. Since it is performed by the second drive motor, not only efficient mixing due to revolution rotation and rotation rotation can be realized, but also the configuration of the one and the other support shafts for supporting the rotating cage on the support base is Since it is extremely simple, it can be manufactured at low cost in a short time. Further, the rotation (rotation) of the mixing container is such that the second drive motor fixed to the rotating cage rotates (rotates) via a shaft portion formed at one end of the mixing container. Unlike a mixing container, which does not have a small bevel gear as a constituent element, it is possible to effectively prevent noise due to the generation of meshing noise of the gear, and further, the powder or the like mixed into the small bevel gear enters. Since it does not occur, it is possible to prevent the risk of black foreign matter being mixed in the powder or the like to be mixed. Further, rotation of the rotating cage (revolution of the mixing container) is performed by the first drive motor fixed to the support base, and rotation of the mixing container is performed by the second drive motor fixed to the drive cage. Therefore, the shape of the mixing container is not limited to a particular shape, and therefore the degree of freedom in designing the mixing container can be expanded. Further, according to the mixer of the second aspect of the present invention, the stirring blade has a third structure that is fixed to the rotating cage.
By the driving motor of the above, not only does the powder or the like put into the mixing container collide with the stirring blades by its own weight but also it is forcibly rotated in the mixing container, the mixing efficiency can be further improved. .

In the mixer 1 according to the above embodiment, the stirring blade 1 shown in FIG. 6 is used as the stirring blade constituting the second invention.
10 is used, the stirring blades constituting the present invention are not limited to those having such a shape, and the stirring blades constituting the mixer 1 according to the above-described embodiment are not limited to such shapes, for example, stirring blades 130 shown in FIG. Alternatively, three stirring blades 130a similar to the blade 110 may be stacked and fixed using two collars 130b.

[0015]

As is clear from the above description of the embodiments of the present invention, in the mixer according to the present invention, the rotation of the rotating cage (revolution of the mixing container) is performed by the first drive motor. Since the rotation (rotation) of the mixing container is performed by the second drive motor fixed to the rotating cage,
Not only can efficient mixing by orbital rotation and rotation be achieved, but the structure of the one and the other support shafts that support the rotating cage on the support base is extremely simple, so that it is possible to shorten the time. Can be manufactured at low cost. Further, the rotation (rotation) of the mixing container is such that the second drive motor fixed to the rotating cage rotates (rotates) via a shaft portion formed at one end of the mixing container. Unlike a mixing container, which does not have a small bevel gear as a constituent element, it is possible to effectively prevent noise due to the generation of meshing noise of the gear, and further, the powder or the like mixed into the small bevel gear enters. Since it does not occur, it is possible to prevent the risk of black foreign matter being mixed in the powder or the like to be mixed. The rotation of the rotating cage (revolution of the mixing container)
The shape of the mixing container is limited to a specific shape because the first drive motor fixed to the support base and the second drive motor fixed to the drive cage separately rotate the rotation of the mixing container. Therefore, the degree of freedom in designing the mixing container can be increased. Further, according to the mixer of the second aspect, not only the powder or the like put into the mixing container collides against the stirring blade by its own weight, but also the third drive motor fixed to the rotating cage. As a result, the stirring blade is forcibly rotated in the mixing container, so that the mixing efficiency can be further increased.
