[0004]

When the container holder for holding the kneading container is rotated while being tilted, there are some problems in a drive system for imparting a rotating motion to the kneading container. For example, the kneading apparatus described in Japanese Utility Model Publication No. 5-32110 uses a universal joint to rotate the inclined container holder, but the universal joint is expensive and has a limited angle of inclination, and there is a problem in durability. is there. In addition, when a rotation drive motor for rotating the container holder is mounted on the rotating body, the load on the rotation drive motor is increased, and the power supply structure to the rotation drive motor that revolves with the rotation body becomes complicated.

Accordingly, it is an object of the present invention to provide a kneading apparatus which can simplify a mechanism for revolving a container holder holding a kneading container and revolving around an axis inclined with respect to a revolving axis while improving the durability thereof. It is to provide a device.

[0006]

In order to solve the above-mentioned problems, the invention according to claim 1 is a method in which a rotating body driven around a revolving shaft by a revolving drive motor supported by a support is kneaded on a centrifugal side of the rotating body. In a kneading device in which a container holder holding a container is rotatably mounted around an axis inclined with respect to the revolution axis, a rotation pulley is coaxially provided on the container holder,
A rotating force imparting pulley having the same diameter as the rotating pulley is provided on the rotating body on the opposite side of the container holder with the orbital axis interposed therebetween, and between the rotating force imparting pulley and the rotating pulley, a circle bridged between the two pulleys. A guide pulley for bending the belt between the two pulleys is provided.

In the kneading apparatus having the above structure, since the rotation pulley and the rotation applying pulley have the same diameter, the two belt portions of the round belt stretched between the two pulleys are guided while maintaining their parallelism. It can be in contact with a pulley. Therefore, uneven wear of the round belt due to friction between the guide pulley and the round belt and falling off of the belt can be prevented. Further, since the rotation applying pulley is provided on the rotating body opposite to the container holder with respect to the revolving shaft, a wide space for disposing the guide pulley can be secured between both pulleys. Therefore, since a guide pulley having a relatively large diameter can be used, the round belt can be bent with a large curvature between the two pulleys, so that the load applied to the belt can be reduced. Therefore, the durability of the round belt connecting the two pulleys is greatly improved.

According to a second aspect of the present invention, in the kneading apparatus according to the first aspect, an annular body arranged around the orbital shaft and coaxial with the orbital shaft is operably connected to the rotation applying pulley, The annular body is rotatably driven by a rotation drive motor supported by the support.

According to the above construction, the rotational driving force of the rotation drive motor can be transmitted from the annular body concentric with the revolving shaft to the rotation pulley via the rotation force applying pulley, so that the container holder holding the kneading container can be used. The rotation drive control can be performed independently of the revolution drive control by the revolution drive motor. Therefore, optimal kneading or kneading and defoaming by revolving and rotation can be performed according to the amount and properties of the non-kneading material. In addition, since the rotation drive motor is supported by the support together with the revolution drive motor, the load on the revolution drive motor can be reduced and the structure for supplying power to the rotation drive motor can be simplified.

According to a third aspect of the present invention, in the kneading apparatus according to the first aspect, an annular body disposed around the orbital shaft and coaxial with the orbital shaft is connected to be able to interlock with the rotation applying pulley, The annular body is fixed to the support.

According to the above construction, the annular body fixed to the support and the rotation applying pulley attached to the revolving rotating body are connected to be able to interlock with each other, so that the container holder moves with the revolving motion of the container holder. Can be rotated without independent driving force. Therefore, an inexpensive kneading apparatus having a simple structure can be provided.

That is, in this embodiment, a rotation shaft 10 protrudes from the bottom of the container holder 9, and the rotation axis of the rotation shaft 10 intersects the revolving shaft 6 above the support member 11 attached to the rotating body 7. Thus, it is rotatably held through the bearing 12 at an inclination angle of about 45 °. The kneading container 8 is fixedly held in the container holder 7 by a holding lid 13 attached to an upper portion of the container holder 9.

A rotation pulley 14 is integrally provided on a lower outer peripheral wall surface of the container holder 7. A pulley shaft 16 parallel to the revolving shaft 6 is rotatably mounted on a rotating body 7 opposite to the container holder 9 with the revolving shaft 6 interposed therebetween via a bearing 17. A rotating force applying pulley 18 is fixed to the pulley shaft 16.
As can be seen from FIG. 2, the rotating pulley 14 and the rotating force applying pulley 18 have the same diameter.
An endless round belt 19 having a round cross section is wound around 4,18.

Further, a guide pulley 20 for bending the round belt 19 between the two pulleys 14 and 18 to change the direction is rotatably mounted on the rotating body 7 via a bracket 21. As shown in FIG.

Therefore, the kneading container 8 held in the container holder 9 can be rotated at an arbitrary rotation speed by the driving force of the rotation driving motor 26. That is, the speed ratio between the revolution of the kneading container 8 and the rotation of the kneading container 8 can be arbitrarily set according to the amount and properties of the non-kneading material in the kneading container 8 (the rotation can be stopped during the revolution). The stirring and kneading action can be performed under the optimum conditions for the non-kneaded material in 8. Further, since the start and stop times of the rotation and revolution of the kneading container 8 can be arbitrarily adjusted, the defoaming action of the non-kneading material in the kneading container 8 can be effectively performed.

In the kneading apparatus having the above structure,
Since the rotation pulley 14 and the rotation force imparting pulley 29 have the same diameter, the two belt portions of the round belt 19 stretched between the pulleys 14 and 18 keep contact with the guide pulley 20 while maintaining their parallelism. It will be. Therefore, it is possible to prevent the round belt 19 from being unevenly worn or dropped due to friction between the guide pulley 20 and the round belt 19.
