FIG. 1 shows a state in which the upper ends of the containers 4 and 4 are opened. However, after putting the material into the containers 4 and 4, the upper ends of the containers 4 and 4 are closed with a lid (not shown). Become.

The revolution rotating device 1 having the above-described configuration is accommodated in a casing 7, and the casing 7 includes a substantially rectangular (rectangular or square) bottom plate 8 and a casing body 9 that closes an upper space of the bottom plate 8. Yes. In addition, at the four corners of the bottom plate 8, vertical fixing members 10 (only two are shown in FIG. 1) are installed. One end of an anti-vibration mechanism 11 is attached to each fixing member 10, and a fixed base 12 having a horizontal plane is fixed via these four anti-vibration mechanisms 11. The fixed base 12 constitutes a fixing member that is inherently provided in the revolving rotation apparatus 1. The fixed base 12 supports (attaches) the components including the rotation mechanism 5 and the revolution mechanism 6 that constitute the revolution / rotation device 1. The anti-vibration mechanism 11 may be composed of any structure as long as it has a self-damping property.

The rotating part 2 is attached to a horizontal plate-like horizontal plate part 2A that is attached to the revolution shaft 13 having a vertical revolution axis X1 so as to rotate integrally therewith, and both front and rear ends of the horizontal plate part 2A. A front and rear pair of front plates 2B and a rear plate 2B (only the rear plate 2B is shown in FIG. 1) having a substantially inverted trapezoidal shape when viewed in the front-rear direction.

Support members 14 and 14 that rotatably support the container holders 3 and 3 are fixed to the left and right ends of the front and rear plate portions 2B and 2B. Each support member 14 is inclined so as to be positioned closer to the revolution axis X1 toward the upper end. The inclination angle is about 45 degrees, but any other inclination angle may be used, and an up / down (vertical) posture that is not inclined may be used. Each container 4 is held by a container holder 3. Further, as shown in FIG. 2, each container holder 3 is open at the top, and is formed with a recessed portion 3A that is fitted with a bottomed cylindrical container 4 and can rotate integrally. Furthermore, each container holder 3 includes a rotating shaft 3B that rotates about the rotation axis X2, and is supported via bearings 15 and 16 provided on the upper and lower sides.

As shown in FIGS. 1 and 4, the revolving mechanism 6 includes a revolving direct drive motor 17 that is a revolving motor attached to the fixed base 12, and a pair of upper and lower bearings 19 at substantially the center of the revolving direct drive motor 17. , 20 and the above-described revolution shaft 13 that is rotated around the revolution axis X1 by the revolution direct drive motor 17.

The revolving direct drive motor 17 is fixed to the fixed base 12 with a screw (not shown) or the like in a state of being inserted into a circular through hole (not shown) formed at a substantially central portion of the fixed base 12. The revolving direct drive motor 17 includes a casing 17A, a stator (not shown) accommodated in the casing 17A, and a rotor (not shown). By supplying power to the stator, the rotor rotates to rotate the revolution shaft 13. Thereby, the rotating part 2 rotates around the revolution axis X1, and the containers 4 and 4 are revolved. Electric power is supplied to the revolving direct drive motor 17 via an electric wire (cable) (not shown). In this way, the revolving direct drive motor 17 directly transmits the rotational force from the revolving shaft 13 that is the output shaft to the rotating unit 2 that is the drive target.

The rotation mechanism 5 converts the rotation force of the rotation direct drive motor 18 that is a rotation motor and the rotation drive shaft 23 that constitutes the rotation shaft (output shaft) of the rotation direct drive motor 18 into the rotation force of the containers 4 and 4. And a conversion mechanism 24 for conversion. The rotation drive shaft 23 is configured as a hollow shaft, and is rotatably fitted over the revolution axis X1 via a pair of upper and lower bearings 21 and 22 (see FIG. 3).

The direct drive motor 18 for rotation is placed on the horizontal plate part 2A of the rotating part 2 and fixed with screws or the like. The direct drive motor 18 for rotation includes a casing 18A, a stator (not shown) accommodated in the casing 18A, and a rotor (not shown). By supplying power to the stator, the rotor rotates to rotate the rotation drive shaft 23. As a result, the rotation shaft 3B (see FIG. 2) rotates around the rotation axis X2 via the conversion mechanism 24 to rotate the container 4. For supplying electric power to the direct drive motor 18 for rotation, electromagnetic induction power transmission means (not shown) for supplying electric power in a non-contact manner by electromagnetic induction can be used. This electromagnetic induction power transmission means is composed of two windings (coils) provided facing each other. Thus, the rotation direct drive motor 18 directly transmits the rotational force from the rotation drive shaft 23 that is the output shaft to the conversion mechanism 24 that is the drive target.

Further, the rotation axis X3 of the direct drive motor 18 for rotation and the revolution axis X1 of the revolution shaft 13 are set on the same axis (on the revolution axis 13 of the same axis). Therefore, even if the rotation direct drive motor (rotation motor) 18 rotates together with the rotating portion 2 by rotation around the revolution axis X1, the rotation axis X3 and the revolution axis X1 of the rotation motor 18 are on the same axis. Therefore, the centrifugal force applied to the rotation motor 18 is uniformly applied to the rotation drive shaft (rotation shaft) 23 of the rotation motor 18. Therefore, the revolution rotation device with high durability of the rotation direct drive motor (rotation motor) 18 can be provided. Further, the rotation direct drive motor 18 is provided on the rotating portion 2 and is disposed at a position closer to the revolution axis X1 than the two containers 4 and 4. In other words, the rotation direct drive motor 18 is arranged at the rotation center on the rotation unit 2, and the position outside the rotation center on the rotation unit 2, that is, the horizontal direction outer side (laterally outward) of the rotation direct drive motor 18. ), Two containers 4 and 4 are arranged. Thereby, further downsizing can be achieved in the height direction of the apparatus.

The conversion mechanism 24 is composed of an interlocking mechanism that interlocks the rotation shaft 3B of the container holder 3 and the rotation drive shaft (rotation shaft) 23. The conversion mechanism 24 is for a transmission gear 25 that is externally fitted so as to rotate integrally with the rotation drive shaft 23, and for a container holder that is externally fitted so as to rotate integrally with the container holder 3 and meshes with the transmission gear 25. And a gear 26. Here, the outer diameter dimension of the transmission gear 25 and the outer diameter dimension of the container holder gear 26 are set to substantially the same size. By changing the outer diameter dimension of the transmission gear 25 and the outer diameter dimension of the container holder gear 26 and appropriately changing the gear ratio between them, the centrifugal force acting on the containers 4 and 4 at the same rotational speed increases or decreases. It is also possible to set as follows. It is also possible to provide a switching mechanism that can switch the rotation direction transmitted by the conversion mechanism 24 between the normal rotation direction and the reverse rotation direction. Therefore, when the rotation direct drive motor 18 is driven, the rotational force from the rotation drive shaft 23 is transmitted from the transmission gear 25 to the container holder gears 26, 26, and the container holders 3, 3 rotate. Thereby, the containers 4 and 4 are rotated and the material in the containers 4 and 4 is processed (for example, stirring and defoaming process).

As described above, by disposing the rotating part 2 on the fixed base 12, the distance between the rotating part 2 and the fixed base 12 can be reduced, and the center of gravity of the entire apparatus is lowered to drive the apparatus stably. Can be made.

Further, by attaching a revolving direct drive motor (revolving motor) 17 for driving the revolving shaft 13 to the fixed base 12, it is possible to make the apparatus compact in the height direction of the apparatus. In particular, configuring the rotation motor and the revolution motor with a direct drive motor is advantageous in making the apparatus compact in the height direction.

The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the gist of the present invention. For example, the specific configuration of the direct drive motors 17 and 18 may be other than the configurations shown in FIGS.

In the above-described embodiment, the rotation motor 18 is mounted on the rotation unit 2, but the rotation motor 18 may be mounted below the rotation unit 2.

In the above embodiment, the revolution motor 17 is attached in a state of penetrating the fixed base 12. However, the revolution motor 17 is attached in a state of being placed on the fixed base 12, or the upper surface of the motor is attached to the lower surface of the fixed base 12. You may attach the revolution motor 17 in the state contact | abutted. Further, although the rotation motor 18 is disposed above the revolution motor 17, on the contrary, the rotation motor 18 may be disposed below the revolution motor 17.

In the above embodiment, the number of containers 4 is plural, specifically two, but three or more may be provided, or only one container 4 may be provided. In addition, in FIG. 1, the revolution device 1 including the container 4 is shown, but the revolution device 1 including only the container holder 3 may be used.
