Recently, a mixing and stirring apparatus has been proposed in which an object to be treated is placed in a container and revolves while rotating the container. Since a stirring blade is not used, it is possible to prevent foreign matter from entering and exiting the stirring blade. It can produce high-purity thick film pastes (silver paste, copper paste, carbon paste, dielectric paste, etc.) used especially in electronics, and optimal mixing, stirring, defoaming, etc. as pretreatment of these pastes. It is drawing attention as a mixing and stirring device for performing.

In the mixing and stirring apparatus in which the container for accommodating the object to be processed is rotated at a high speed, it is necessary to securely fix the container to the container holder and rotate the container in order to perform the mixing and stirring efficiently and also from the viewpoint of safety.

As a result, the mixing and stirring become insufficient or, in severe cases, the fixing member interferes with the mixing and stirring device, which is one of the causes of the damage of the mixing and stirring device. There was no eager fixation method eager. Also, since the clamping force is fixed when using the fixing member, the container is rotated at a high speed, or when the viscosity of the workpiece increases, the clamping force is insufficient and the container rotates relatively little by little in the container holder. This causes wear and noise of the container and the container holder, or damages the container and the container holder.

Further, in order to ensure a certain tightening force, a disadvantage is that an expensive dedicated container in which the size of a portion to be brought into contact with the fixing member is processed within a predetermined dimensional tolerance must be prepared. there were. Further, there is a disadvantage that a container whose dimensions change due to abrasion and deviates from a predetermined dimensional tolerance cannot be used, and that a great number of man-hours and attention must be paid to manage the dimensional tolerance.

In the type in which the notch and the projection are engaged, it is necessary to ensure that the notch and the projection are engaged when the container is accommodated, and the container is accommodated in the container holder. Depends on the worker's sense,
It was difficult to completely prevent work errors.

The second embodiment of the present invention differs from the first embodiment in the configuration of the fixing ring 30, the sliding ring 31, and the band-shaped leaf spring 32 in FIGS. Fixing ring 30
Is formed in a ring shape having the same inner and outer diameters as the fixing ring 3 of the first embodiment, and is fixed to the container holder 2. A cutout groove 30b is formed in the upper part of the fixing ring 30 to engage the escape groove 30a with one end 32a of the band-shaped leaf spring 32.

Then, one end 32a of the band-shaped leaf spring 32 is engaged with the notch groove 30b of the fixing ring 30, and the other end 32b of the band-shaped leaf spring 32 is engaged with the notch groove 31b of the sliding ring 31, so that the inside of the container holder 2 is kept. It is arranged in. The other parts are the same as in the first embodiment, and the description thereof will be omitted.

FIG. 12 and FIG. 13 show a third embodiment of the present invention.
, A spring hook hole 3e is formed in the fixing ring 3,
The operating knob 35 fixed to the sliding ring 4 is provided with a spring hook hole 35a, and a tension spring 36 is disposed between the spring hook hole 3e and the spring hook hole 35a to wind the sliding ring 4 around the spring ring. 5 is urged in a direction to reduce the inner diameter. Other configurations are the same as those of the first embodiment, and the same portions are denoted by the same reference numerals in the drawings, and description thereof will be omitted.

The present invention is configured as described above,
Hereinafter, the operation will be described. First, the operation of the mixing and stirring device 1 will be described. In FIG. 8, an object to be processed (not shown) is accommodated in a container 6, sealed with a lid 6 b, and then accommodated in a container holder 2.

When a power switch (not shown) is turned on, the drive motor 23 rotates in the direction of arrow D, and the rotation is transmitted through the winding transmission member 22, the pulley 21, and the support shaft 14 to the arm 12.
To rotate the arm 12 in the direction of arrow F.
As the arm 12 rotates, the container holder 2 also revolves in the direction of arrow F.

At this time, the planetary gear 16 revolves while meshing and contacting around the sun gear 15 and rotates in the direction of arrow G. The rotation is caused by the winding transmission member 20, the pulley (not shown), and the universal joint (see FIG. Container holder 2 via not shown)
To rotate the container holder 2 in the direction of arrow A, the object is mixed by receiving the acceleration in the radial direction of the revolution by the revolution and the Coriolis acceleration by the revolution and the revolution.

Next, the accommodation of the container 6 in the container holder 2 according to the first embodiment of the present invention will be described with reference to FIGS.

When the rotation of the container holder 2 is stopped, in FIG. 5, the winding spring 5 is in an open state, and the inner diameter thereof is slightly larger than the outer peripheral portion 6c of the container 6. , The container 6 is simply the container holder 2
7 can be easily accommodated in the container holder 2 without any obstacle as shown in FIG.

Here, as described above, when the mixing and stirring device 1 is operated to rotate the container holder 2 in the direction of arrow A,
The container 6 accommodated also rotates in the direction of arrow A, but since a high-viscosity liquid object to be treated is accommodated in the container 6, a force in the direction of constantly stopping the rotation is applied to the container 6. Works. On the other hand, the fixing ring 3 rotates in the direction of arrow A together with the container holder 2, but the sliding ring 4 is in contact with the container 6 on which the stopping force is acting, so that the sliding ring 4
Also, a force in the direction to stop the rotation is applied, and the sliding ring 4 relatively rotates in the arrow B direction.

With the relative rotation of the sliding ring 4, the winding spring 5 is wound by the opening margin θ ₁ in the direction in which the effective number of turns increases (the direction of arrow B), and the inner diameter of the winding spring 5 becomes the outer peripheral portion 6 c of the container 6. After contacting with, it is further wound by the interference angle θ ₂ , and FIG.
7, the inner diameter is reduced from the position shown by the solid line to the position shown by the broken line, and the outer peripheral portion 6c of the container 6 is strongly fastened and fixed in the direction of arrow C. As a result, the container 6 rotates together with the container holder 2 in the direction of the arrow A to surely mix and stir the object to be processed.

Further, as described above, the tightening force of the container 6 automatically increases in proportion to the magnitude of the force at which the container 6 stops, that is, a self-amplifying (self-locking) braking force acts. Since the contact length of the coil spring 5 with the container 6 is very long, 3.5 times its circumference, even if the viscosity of the object to be processed or the rotation speed of the container 6 is changed, no special adjustment is performed. The container 6 can be completely prevented from rotating relative to the container holder 2 with a strong frictional force that never causes the container 6 to slip.

In the second embodiment of the present invention, the rotation of the container holder 2 shown in FIGS.
The sliding ring 31 to which the force in the direction of constantly stopping the rotation is relatively rotated in the direction of arrow H, and the other end 32b of the band-shaped leaf spring 32 is moved in the direction of arrow I with this. The inner diameter of the leaf spring 32 is reduced, and the outer peripheral portion 6c of the container 6 is tightened to be integrally fixed to the container holder 2;
Since the belt-shaped spring 32 is in surface contact with the outer periphery 6c of the container 6, even if the winding angle is smaller than 360 °, the contact area is very large. Therefore, a large frictional force is generated between the outer periphery of the container 6 and the band-shaped spring 32. Therefore, relative rotation of the container 6 with respect to the container holder 2 can be completely prevented.

In the third embodiment of the present invention, an object for mixing and stirring an ultra-high-viscosity object to be processed, in which the force for stopping the rotation of the container 6 is further increased, is shown in FIG.
2, the sliding ring 4 is biased by a tension spring 36 in a direction in which the inner diameter of the winding spring 5 is reduced. Accordingly, the inner diameter of the coil spring 5 is smaller than the dimension of the outer peripheral portion 6c of the container 6 even when the container holder 2 is stopped. The container 6 is inserted into the container holder 2 in a state in which the inner diameter of the winding spring 5 is increased by operating in the L direction against the force of the tension spring 36.

After the container 6 is inserted, the finger 38 is operated with the operation knob 35.
When released, the sliding ring 4 rotates in the direction opposite to the direction of arrow L by the force of the tension spring 36, and the inner diameter of the coil spring 5 becomes smaller, so that the outer peripheral portion 6c is tightened by the force of the tension spring 36.

Here, when the mixing and stirring device 1 is operated,
The sliding ring 4 rotates in the clockwise direction in FIG. 13 to further reduce the inner diameter of the coil spring 5 so that the elastic force of the tension spring 36 is reduced. Since the container 6 is fixed with a greater frictional force by the amount, even when mixing and stirring an object having an ultra-high viscosity, relative rotation of the container 6 with respect to the container holder 2 can be completely prevented.

[0043]

According to the present invention, the fixing ring and the sliding ring which is loosely fitted in the container holder are provided in the container holder as described above, and one end of the winding spring is connected to the fixing ring and the other end is connected to the fixing ring. Since the inner diameter of the winding spring is reduced when the container holder is rotated in the direction of rotation, the container is specially provided for fixing the container when the container is accommodated in the container holder. There is an effect that work can be made unnecessary, and as a result, work errors can be completely prevented without depending on the qualities of the worker.

With the above arrangement, when the mixing and stirring device is stopped, the inner diameter of the coil spring is enlarged and opened, so that the container can be stored in the container holder very easily and in a short time. During operation of the device, the inner diameter of the winding spring is automatically reduced and the outer diameter of the container can be tightened and fixed with a very large frictional force, so that the relative rotation of the container with respect to the container holder can be completely prevented. As a result, there is an effect that the working efficiency is improved and the container can be reliably accommodated in the container holder.

Further, a fixing ring and a sliding ring which is loosely fitted in the container holder are provided in the container holder.
One end of the winding spring is connected to the fixing ring, and the other end is connected to the sliding ring, and the inner diameter of the winding spring is reduced when the container holder is rotated in the rotation direction. The relative rotation of the container is stopped, so that even high-viscosity materials can be mixed and agitated reliably. Also, it is necessary to completely prevent wear of the container and control the dimensions of the container. This has the effect of eliminating noise and preventing the generation of noise.

When one end of a band-shaped leaf spring arranged so as to be wound around the outer periphery of the container is connected to the fixing ring, and the other end is connected to the sliding ring, the sliding of the sliding ring is performed when the container holder is rotated in the rotation direction. Since the inner diameter of the band-shaped leaf spring was reduced with the rotation delay and the container was tightened during rotation to stop the relative rotation of the container with respect to the container holder,
The tightening force is increased in proportion to the rotation speed of the container holder to automatically secure the container with the optimal tightening force and the greater frictional force due to surface contact, and automatically corrects errors in the outer diameter of the container. Therefore, an excellent effect that an inexpensive commercially available container can be used without using a special dedicated container can be obtained.

Further, a spring having one end connected to the fixed ring and the other end connected to the sliding ring is provided, and the spring is biased to rotate the sliding ring in a direction in which the inner diameter of the wound spring or the band-shaped leaf spring becomes smaller. As a result, the initial tightening force is applied to the container even when the mixing and stirring device is stopped, and during operation, the tightening force is further increased so that the container can be securely fixed. There is an effect that a substance can be efficiently mixed and stirred.
