[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stirring and defoaming device for stirring and defoaming a fluid material such as an industrial paste material.

[0002]

2. Description of the Related Art Conventionally, for stirring and defoaming a material to be kneaded such as an industrial paste material, a stirring and degassing apparatus configured to orbit the kneading container containing the material to be kneaded while revolving on a predetermined orbit A foam device is used. In this type of stirring and defoaming device, the material to be kneaded in the kneading container is pressed against the inner wall of the kneading container by the centrifugal force acting by the revolution movement of the kneading container, and the bubbles existing in the material to be kneaded are discharged to the outside. The material to be mixed in the kneading container is agitated by the rotation of the kneading container.

As a conventional stirring / defoaming device, a stirring / defoaming device 11 shown in FIG. 8 can be exemplified. The stirring method 11 is
The revolution body 13 is attached to a revolution shaft 131 projecting to the upper surface side of a support plate 12 elastically supported by a main body container (not shown). The revolution body 13 is attached to the revolution shaft 131 at one end (right side in FIG. 8) in a state of being inclined upward with respect to the upper surface of the support plate 12, and the revolution drive motor 14 is driven to revolve. The revolution shaft 131 is transmitted to the shaft 131 to rotate about the revolution shaft 131.

The other end of the revolution body 13 (left side in FIG. 8)
Includes a container holder 16 for holding the kneading container 15.
However, the rotation shaft 161 is rotatable along the upper surface of the revolution body 13
Is supported by. The drive of the rotation drive motor 17 provided at one end of the revolution body 13 is transmitted to the container holder 16 via the belt 171. As the container holder 16 rotates, the kneading container 15 rotates around the revolution shaft 161 as the revolution body. It is designed to rotate on top of 13.

This stirring and defoaming device 11 includes a container holder 16
The kneading container 15 held at the position revolves around the revolution shaft 131 as the revolution axis along with the rotation of the revolution body 13 driven by the revolution drive motor 14, and the rotation drive motor 17 drives the rotation shaft 161 as the rotation axis. Rotate around,
The material to be kneaded in the kneading container 15 is pressed against the inner wall of the kneading container 15 by the centrifugal force exerted by the revolving motion of the kneading container 15 to be defoamed, and is agitated by the rotation motion of the kneading container 15.

[0006]

In such a stirring and defoaming apparatus, a general material to be kneaded can be well stirred and defoamed, but when the material to be kneaded has poor fluidity or the kneading container is When the inner diameter is small, a stirring mechanism may be provided so that the material to be kneaded in the kneading container can be sufficiently stirred.

For example, in the example of the stirring and defoaming apparatus 11 shown in FIG. 8, as the stirring mechanism 21, a feed screw 23 is pivotally supported by a guide frame 22 provided on the revolution body 13, and the feed screw 23 is provided with a base of an arm 24. It has a mechanism in which the ends are screwed together, the feed screw 23 is rotated in the forward and reverse directions by the drive of the vertical drive motor 25, and the arm 24 is moved up and down by the screw operation of the feed screw 23 and the arm 24. Then, when the arm 24 descends, the stirring blade 241 of the arm 24 enters the kneading container 15 and is in a state of being offset from the rotation shaft 161. Therefore, the stirring rod 241 apparently rotates around the rotation axis of the kneading container 15 with respect to the kneading container 15 which rotates, so as to stir the material to be kneaded in the kneading container 15. There is.

As described above, in the conventional stirring and defoaming apparatus 11, the material to be kneaded is stirred by the stirring mechanism 21 in the material to be kneaded in the kneading container 15 that revolves around the revolution axis and the rotation axis. Can be sufficiently stirred in the kneading container 15. However, the conventional stirring mechanism 21 requires a mechanism for moving the stirring blade 241 up and down in order to move the stirring blade 241 in and out of the kneading vessel 15 held by the vessel holder 16, so that the configuration is complicated and the apparatus is large. Will turn into.

In stirring and defoaming the material to be kneaded,
When transferring the material to be kneaded from the kneading container to a container suitable for the purpose of use, avoid that the material to be kneaded adheres to the kneading container, causing leakage of the material to be kneaded or sticking to the user's hand. Therefore, the material to be kneaded is filled in the kneading container in an amount to be used once and then degassed by stirring.

In this case, a plurality of kneading containers may be arranged around the axis of the container holder, and each kneading container may be revolved in the container holder to stir the materials to be kneaded in the plurality of kneading containers at once. Although considered, in the stirring mechanism 21 having the above-described configuration, the stirring blade 241 is rotated in the kneading container 15 in order to rotate the container holder 16 while the stirring blade 241 is fixed at a predetermined position with respect to the revolution body 14. It will hinder the orbital movement. Therefore, there is a problem that the conventional stirring mechanism 21 cannot be used when stirring and defoaming the plurality of kneading vessels 15.

Therefore, without providing a complicated mechanism,
In order to stir the materials to be kneaded in the plurality of kneading containers, it is also considered to put a ceramic ball together with the materials to be kneaded in the kneading container and agitate and degas. However, there was a problem that ceramic balls were mixed in and it was difficult to use the material to be kneaded after the stirring and defoaming treatment.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a stirring and defoaming apparatus capable of sufficiently stirring and defoaming the material to be kneaded in the kneading container with a simple structure.

[0013]

In order to solve the above problems, the stirring and defoaming apparatus of the present invention holds a kneading container by a container holder rotatably provided on a rotating body, and rotates the container holder by the rotation. A stirring and defoaming device for stirring and defoaming the material to be kneaded in the kneading container by rotating the rotation axis of the body as the revolution axis and rotating the rotation axis of the container holder as the rotation axis. A stirring member rotatably supported with respect to a rotation axis in a direction along the rotation axis of the container holder in the kneading container held by, and configured integrally with the stirring member, and works by the revolution of the kneading container. A stirring mechanism including a weight for rotating the stirring member with respect to the rotating body in a predetermined posture by a centrifugal force is provided.

In this stirring and defoaming device, while the kneading container filled with the material to be kneaded is held by the container holder, the rotating body is rotated and the container holder provided on the rotating body is rotated, so that the container holder is rotated. Is revolved around the rotation axis of the rotating body as the revolution axis and the rotation axis of the container holder is rotated around the rotation axis to stir and defoam the material to be kneaded in the kneading container.

The stirring member constituting the stirring mechanism is
It revolves around the rotation axis of the rotating body along with the container holder. By this revolving movement, a centrifugal force acts on the weight that revolves together with the stirring member, and the weight is pressed against the outer peripheral direction of the rotating body. On the other hand, the kneading container revolves around the rotation axis of the rotating body of the rotating body together with the container holder and rotates about the rotation axis of the container holder. Since the stirring member constituting the stirring mechanism is in a state of being rotatably supported with respect to the rotation axis in the direction along the rotation axis of the container holder,
A certain posture is maintained on the rotating body by the centrifugal force acting on the weight. Therefore, the stirring member apparently rotates in the kneading container, and the material to be kneaded in the kneading container is stirred by the stirring member.

As described above, this stirring and defoaming device is simple in that the kneading container held by the container holder is provided with the stirring member rotatably supported about the rotation axis in the direction along the rotation axis of the container holder. With such a configuration, the material to be kneaded in the kneading container can be sufficiently stirred. Therefore, according to this stirring and defoaming device, the material to be kneaded in the kneading container can be sufficiently stirred and defoamed with a simple configuration.

In this stirring and defoaming device, the kneading container held by the container holder is preferably a syringe container. In the case of a kneading container with a small diameter such as a syringe container,
Simply by making the kneading container orbital motion and rotation motion,
The material to be kneaded in the kneading container may not be sufficiently stirred. However, according to this stirring and defoaming device, since the material to be kneaded in the kneading container is stirred by the stirring member, the material to be kneaded in the kneading container can be sufficiently stirred, and the material to be kneaded in the kneading container can be sufficiently stirred. Can be degassed.

Further, in this stirring and defoaming device, it is preferable that the container holder is configured to hold a plurality of kneading containers. In the stirring mechanism, the stirring member revolves together with the kneading container arranged along the axis of the container holder in a state in which the stirring member maintains a predetermined posture with respect to the rotating body, so that the stirring member mixes in the container holder. The material to be kneaded in the kneading container can be stirred without hindering the revolving movement of the container. Therefore, by configuring the container holder to hold a plurality of kneading containers, it is possible to hold a large number of kneading containers at one time with the container holder, and even when the material to be kneaded is used multiple times, a large number of kneading containers can be efficiently used. Can be well degassed by stirring.

Then, as indicated by an arrow YC in FIG. 2, the kneading container 8 is rotatably held in the kneading container 8 about the axis of the kneading container 8.

When stirring and defoaming the material to be kneaded k using the stirring and defoaming apparatus 1 having such a configuration, first, the material k to be kneaded
The kneading container 8 filled with is held in the container holder 6 by the adapter 62. Next, as shown in FIG. 2, the tip end portion 7A of the stirring rod 7 is inserted into the tip end opening portion 82 of the kneading container 8 and the base end opening portion 81 is closed by the lid 71, so that the kneading container 8 is moved in the axial direction. The stirring rod 7 is attached inside the kneading container 8 so as to be rotatable along the same. As a result, the stirring bar 7 is in a state of being rotatably supported on the rotation axis of the container holder 6 along the rotation axis.

The drive motor 3 is driven to rotate the revolution base 4 with the revolution drive shaft 31 as a rotation shaft as shown by an arrow YA in FIG. 1, and the container holder 6 with the rotation drive shaft 32 as a rotation shaft. 1, the container holder 6 is caused to revolve around the revolution drive shaft 31 about the revolution axis and the rotation drive shaft 32 about the revolution axis. As a result, the material k to be kneaded in the kneading container 8 is pressed against the inner wall of the kneading container 8 by the centrifugal force exerted by the revolution motion of the kneading container 8 to be defoamed, and is agitated by the rotation motion of the kneading container 8.

At this time, the stirring rod 7 attached to the kneading container 8 revolves together with the container holder 6 with the revolution drive shaft 31 as the revolution axis, and the centrifugal force due to this revolution acts on the weight 72. However, the agitating rod 7 has a kneading container 8 at its tip 7A.
Is rotatably inserted into the tip opening 82 of the
Since the lid 71 is rotatably provided on the slightly distal end side of the base end portion 7B and is attached to the kneading container 8 rotatably with respect to the rotation axis in the direction along the rotation axis of the container holder 6,
A certain posture is maintained on the revolution base 4 by the centrifugal force exerted by the revolution movement of the revolution base 4. Therefore, apparently,
In the kneading container 8 held by the container holder 6, the stirring rod 7
The material k to be kneaded in the kneading container 8 is agitated by rotating as shown by an arrow YC in FIG.

As described above, according to the stirring and defoaming apparatus 1, the stirring rod is rotatably provided in the kneading container 8 held by the container holder 6 with respect to the rotation axis in the direction along the rotation axis of the container holder 6. With the simple configuration of providing 7, the material to be kneaded in the kneading container 8 can be sufficiently agitated, and the material to be kneaded in the kneading container 8 can be sufficiently agitated and defoamed.

The stirring and defoaming apparatus of the present invention is not limited to the stirring and defoaming apparatus 1 of the above-mentioned embodiment, and may be appropriately changed without departing from the gist of the present invention. In the above-described embodiment, the stirring rod 7 is formed in a substantially U-shape from the slightly proximal end side to the central portion of the tip end portion 7A, but the kneading material k in the kneading vessel 8 is mixed in the kneading vessel 8 The shape is arbitrary and can be appropriately changed as long as it can be sufficiently agitated according to the rotation movement of the. For example, as shown in FIG. 4, the material k to be kneaded moves up and down in the kneading vessel 8 sufficiently by forming a spiral shape from the slightly proximal end side to the central portion of the tip portion 7A of the stirring rod 7. It can be stirred. Further, the stirring rod 7 may be formed in a flat plate shape.

In the above embodiment, the base end portion 7 of the stirring rod 7 is used.
Although the weight 72 is provided in B, if the stirring rod 7 can be relatively rotated in the kneading container 8 by the centrifugal force acting on the stirring rod 7 with the rotation operation of the revolution base 4, The weight is arbitrary, and the weight 72 may not be provided externally. That is, the weight of the rod itself may be the weight.
The weight 72 is attached to the stirring rod 7 by referring to the base end portion 7 of the stirring rod 7.
B does not have to be bent and attached in one direction, but may be bent and attached in the opposite direction as shown in FIG. 5, for example. In FIG. 1, the stirring bar 7
Although the weight 72 of FIG. 2 shows the state of stirring and defoaming while being positioned on the opposite side beyond the rotation axis of the revolution base 4, it does not necessarily need to exceed the rotation axis of the revolution base 4.

In the above-described embodiment, the stirring rod 7 is held in the revolving base 4 in a predetermined posture mainly by the centrifugal force acting on the weight 72,
Although it apparently rotates in the kneading container 8, any method of holding the stirring rod 7 on the revolution base 4 in a predetermined posture can be used. For example, the magnet provided on the revolution base 4 and the base end of the stirring rod 7 can be used. It may be a magnetic force with a magnet provided in 7B. Further, the stirring and defoaming device of the present invention can be suitably used for stirring and defoaming a material to be kneaded filled in a kneading container having a small inner diameter, such as the kneading container 8 which is a syringe container. The size and shape of the kneading container 8 are arbitrary and may be appropriately changed depending on the amount of the material to be kneaded and the like.

In the above embodiment, the case where the container holder 6 holds one kneading container 8 for degassing by stirring is described. However, the number of the kneading containers 8 held by the container holder 6 is not limited to one, and may be appropriately changed depending on the number of times and the amount of the material k to be kneaded and the size of the kneading container 8 or the container holder 6. . In this case, with the stirring rod 7 attached to each kneading container 8 arranged around the axis of the container holder 6, the container holder 6 is revolved and revolved so that each stirring rod 7 moves to the revolution substrate 4. On the other hand, since the orbital motion of the kneading container 8 in the container holder 6 revolves in a predetermined posture, the stirring member 7 does not hinder the orbital motion of the kneading container 8 in the container holder 6 and The kneaded material k can be stirred. Therefore, a large number of kneading containers can be held at one time by the container holder, and even when the material to be kneaded is used a plurality of times, the large number of kneading containers can be efficiently stirred and degassed.

In the stirring and defoaming apparatus 1 of the above-mentioned embodiment, the kneading container 8 held by the container holder 6 is simply revolved and revolved to stir and defoam the material k to be kneaded in the kneading container 8. It was of a configuration that does. However, by adopting a configuration in which the kneading container 8 is revolved and rotated while maintaining a vacuum, the air bubbles in the material to be kneaded k are easily released to the outside, and the time required for stirring and defoaming can be shortened. ,
The stirring and defoaming process can be efficiently performed. An example of a configuration in which the inside of the kneading container 8 is in a vacuum state is a configuration in which a lid is provided so as to cover the upper surface of the support plate 2 to the revolution base 4 in an airtight state and the inside of the lid is sucked by a suction means. Further, according to the structure in which the kneading container 8 held by the container holder 6 is provided with a lid so as to cover the kneading container 8 in an airtight state and the inside of the kneading container 8 is sucked by the suction means, the kneading container 8 is in a vacuum state. It is possible to shorten the time required for the above, further shorten the time required for stirring and defoaming, and efficiently perform the stirring and defoaming treatment.

The mechanism for revolving and rotating the kneading container 8 held by the container holder 6 is not limited to that in the above-mentioned embodiment, and may be appropriately changed. For example, as shown in FIG. 6, a belt 55 is mounted between a pulley 31 a that is concentric with the revolution drive shaft 31 and fixed to the support plate 2 and a pulley 32 a that is fitted on the rotation drive shaft 32. The configuration may be simplified by transmitting the drive of the drive motor 3 to the rotation drive shaft 32 via the, to thereby cause the kneading container 8 in the container holder 6 to revolve and rotate.

In the above-described embodiment, the container holder 6 is provided on one side (right side in FIG. 1) of the revolution base 4 with the revolution drive shaft 31 interposed therebetween, and the balance weight 422 is provided on the other side (left side in FIG. 1). By adjusting the mounting position of the balance weight 422 on the revolution base 4, the weight on the revolution base 4 is balanced. However, as shown in FIG. 7, a pair of holder support portions 41 may be provided at positions symmetrical to each other on the revolution base 4 with the revolution drive shaft 31 interposed therebetween for balancing. According to this configuration, the plurality of kneading vessels 8 can be stirred and degassed at one time. Further, the number of the container holders 6 provided in the holder support portion 41 and the arrangement position on the revolution base 4 are arbitrary as long as the weight balance on the revolution base 4 can be maintained, and may be appropriately changed.
