Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stirring and mixing apparatus capable of uniformly stirring and mixing materials in a container.

[0002]

2. Description of the Related Art When uniformly stirring and mixing materials such as liquids, granules, and powders in a container, a stirring and mixing device for rotating the container may be used.

[0003] This is constructed by combining a holding unit for holding a container and a drive motor for rotating the holding unit. Therefore, in this apparatus, the container is held by the holding unit, and the holding unit is rotated via the drive motor, whereby the container can be rotated and the material in the container can be stirred and mixed.

[0004]

According to the prior art, since the container simply rotates in one direction via the drive motor, the material is partially biased to a part of the container due to the properties of the material. There is a problem that the materials in the mixture cannot be uniformly stirred and mixed, or the processing time required for the stirring and mixing becomes long.

In view of the above-mentioned problems in the prior art, an object of the present invention is to rotate a container and reciprocate a holding member for holding the container back and forth so that an arbitrary material can be uniformly dispersed in a short time. An object of the present invention is to provide a stirring and mixing device capable of stirring and mixing.

[0006]

According to a first aspect of the present invention, there is provided an image forming apparatus comprising: a holding member for holding a container; and a drive motor for rotating the container and reciprocating the holding member back and forth. This is the gist.

The holding member can rotatably hold the container via a support shaft connected to a drive motor.
It can be connected to a drive motor via a support shaft and rotate integrally with the container.

The holding member may hold the container in a detachable manner.

Further, the holding member is mounted on a driving member that swings back and forth, and the drive motor can swing the driving member.

The number of reciprocations of the holding member per unit time and the number of rotations of the container per unit time may be set independently for one of the other.

[0011]

According to the structure of the present invention, the drive motor rotates the container and reciprocates the holding member back and forth, so that the material in the container is not biased and the material in the container can be removed in a short time. Stir and mix uniformly. The material in the container is not only in the vertical direction, but also in the container, with the rotational movement of the container and the back and forth movement of the holding member.
This is because they can also be moved in the front-back direction. However, it is preferable that the container is fixed obliquely to the rotation center axis set in the horizontal direction. Further, the container may be formed in, for example, a rectangular cylindrical shape and the inner surface may be formed with irregularities, or a suitable stirring blade may be formed on the cylindrical inner surface.

The holding member for rotatably holding the container can rotate the container by rotating the support shaft by a drive motor, and there is no need to rotate the holding member itself. The container at this time is held by a holding member via a support shaft that is rotatable relative to the holding member, and the support shaft is connected to a drive motor outside the holding member.

The holding member connected to the drive motor via the support shaft can rotate integrally with the container when the drive shaft rotates the support shaft. However, the container at this time is held by the holding member so as not to rotate relatively.

When the container is detachably held by the holding member, the container can be detached from the holding member when charging and discharging the material, and the material can be charged and discharged outside the holding member.

If the holding member is mounted on the driving member, the holding member can reciprocate the container back and forth through the driving member by oscillating the driving member via the driving motor.

By appropriately setting the number of reciprocations of the holding member per unit time and the number of rotations of the container per unit time,
The processing conditions for stirring and mixing can be optimally set according to the properties of the material. Note that the number of reciprocations of the holding member per unit time and the number of rotations of the container per unit time can be set arbitrarily by setting one to the other independently, so that the ratio of both can be set arbitrarily. By variably setting the rotation speed of the motor, both can be set in conjunction with each other.

[0017]

Embodiments of the present invention will be described below with reference to the drawings.

The stirring and mixing device includes a holding member 11 and a drive motor 21 (FIGS. 1 and 2). The holding member 11 is mounted on driving members 12 and 12 that can swing back and forth.

In the above description, the drive motor 21
It is sufficient that the container Y can be rotated to reciprocate the holding member 11 back and forth.
Each drive mechanism for reciprocating the can be used in any form other than those shown. However, it is preferable that the number of reciprocations of the holding member 11 per unit time and the number of rotations of the container Y per unit time can be set independently of one another.

Further, instead of reciprocating the holding member 11 back and forth so as to be orthogonal to the rotation center axis C of the container Y, the holding member 11 may be reciprocated in the direction of the rotation center axis C of the container Y.

[0031]

As described above, according to the present invention, by providing the holding member for holding the container and the drive motor, the drive motor rotates the container and reciprocates the holding member back and forth. Therefore, there is an excellent effect that the material in the container can be uniformly stirred and mixed in a short time without being biased to a part of the container.
