Description

[Detailed explanation of the invention] (a) Field of the invention The invention relates to a novel stirring device.
More specifically, the present invention relates to a stirring device capable of stirring an object to be stirred while the stirring shaft is constantly moving over almost the entire area of the object to be stirred.

(b) Prior art When carrying out a small-scale dyeing test or chemical treatment test using samples of various types of fibers such as cotton, yarn, knitted fabrics, etc., the sample, water, dye and/or drug are placed in a test pot. Alternatively, a test method in which the product is placed in a beaker and heated under conditions of manual stirring using a glass rod or the like, and a method in which a dye test device or the like equipped with mechanical stirring is used are adopted.

In the manual stirring test method, a container containing the substance to be stirred is stirred for a certain period of time using a glass rod, etc. on an electric heater or in a constant temperature bath, but the equipment used is simple and does not require any special equipment. There are no particular restrictions on the shape or amount of the material to be stirred, and since testing is performed while observing the condition, the material to be stirred does not wrinkle or stain, which is an advantage. , poor reproducibility, and the need to constantly observe and stir the mixture.
There are inherent problems such as the need for safety measures such as burns.

On the other hand, there are machines that shake or rotate one or more containers containing a sample, water, dye, and/or drug in a thermostatic bath, or machines that attach the sample to a holder and move it up and down in a dye solution or chemical solution. When using a test device with a mechanical motion, it is effective as it allows testing on many samples at once, but since the stirring mode is limited, it is not suitable when the samples have different shapes or are large in amount. It becomes impossible to provide sufficient agitation, leading to problems such as wrinkles in the sample, deterioration of texture, and the occurrence of dye spots.

(c) Points of focus The inventors of the present invention have developed a machine that takes advantage of the advantages of the manual stirring method when performing small-scale dyeing tests or chemical treatment tests on samples of various types of fibers, such as fluff, threads, knitted fabrics, etc. As a result of intensive studies to develop a stirring device, we have found that the object to be stirred in a pot or beaker containing samples, water, dyes, and/or chemicals can be stirred over almost the entire area of the object, without stirring only the area where the stirring shaft is located. The present invention was achieved by discovering the fact that effective stirring can be achieved by a mechanism that stirs while moving over the area.

(d) Purpose of the invention The main purpose of the invention is to provide a new stirring device, and the purpose of the invention is to move the stirring shaft over almost the entire area of the object to be stirred, thereby achieving stirring without uneven stirring. Another purpose of the present invention is to provide an efficient apparatus for carrying out small-scale dyeing tests or chemical treatment tests on various fiber samples, without causing wrinkles in the samples and without producing dyed or processed spots. An object of the present invention is to provide a stirring device capable of stirring.

(e) Structure of the invention The purpose of the invention is to convert the rotary movement of the motor 2, which is made up of an index disk 3 fixed to the motor 2 and provided with a slide pin 4 and an arm 6 to which a guide 5 is fixed, into a pendulum movement. a mechanism for converting into
2 are connected via a rotary bearing 11, and includes a mechanism that converts the movement of the tip of the arm 12 into a pointed elliptical (triangular rice ball-shaped) movement in the opposite direction to the rotational movement of the motor 8 using the slide bearing 13 as a fulcrum. , these two mechanisms are connected by a support rod 18, and the tip of the stirring shaft 15 attached to the tip of the arm 12 repeats a pointed elliptical movement in the vertical direction while moving in a direction perpendicular to the plane of the pointed elliptical movement. This is achieved by providing a stirring device with pendulum motion.

(F) Specific description of the configuration One embodiment of the device of the present invention will be described in detail based on the drawings.

Figure 1 shows an outline of a stirring device that has only one stirring shaft, which is a smaller version of the device of the present invention, in which a variable-speed motor 2 with an indexing disk 3 fixed to the rotating shaft and a column 1 are fixed. ing.

An arm 6 having a guide 5 perpendicular to the slide pin 4 is attached to the indexing disk 3, and the rotational motion of the motor 2 is converted into a pendulum motion of the arm 6 by this mechanism.
When the length from the end of the arm 6 to the tip of the arm 6 is b,
The angle α of the arm 6 which swings from the center of the index disk 3 in a direction parallel to the disk surface has the relationship of Sinα=a/b. Therefore, the width of the swing is controlled by the magnitude of the angle α (or the a/b ratio). The period can be arbitrarily adjusted by the rotation speed of the motor 2.

On the other hand, a variable-speed motor 8 having an indexing disk 9 fixed to its rotating shaft is installed on a support rod 18 fixed perpendicularly to the tip of the arm 6, and is divided according to the pendulum movement of the arm 6. The motor 8 having the protruding disk 9 is also given a pendulum motion by the same angle α in the direction of the rotation axis of the motor 8.

An arm 12 is connected to the index disk 9 via a pin 10 and a rotary bearing 11 so as to be orthogonal to the pin 10. A stirring shaft 15 can be attached to the tip of the arm 12 using a set screw 14. Further, the arm 12 is rotated in the vertical direction.
2 can slide up and down, and the arm 12
A slide bearing 13 having a bearing that is movable with respect to the swinging movement is inserted.

The slide bearing 13 can be fixed at any position on the guide 17, and by adjusting this position, the trajectory of the tip of the stirring shaft 15 can be changed to any shape from horizontal to vertical.
For example, by fixing the bearing 13 to the upper part of the groove of the guide 17, the trajectory of the tip of the stirring shaft 15 draws a flat (horizontally long) pointed ellipse with the bearing 13 as a fulcrum and rotating in the opposite direction to the index disk 9. , and slide bearing 1
By fixing 3 to the lower part of the groove of the guide 17,
The trajectory of the tip of the stirring shaft 15 draws a vertically long pointed ellipse that is close to a circle that rotates in the opposite direction to the rotation of the indexing disk 9.

Therefore, as the motor 8 rotates, the tip of the stirring shaft 15 is fixed to the slide bearing 1 fixed to the guide 17.
It is possible to draw an arbitrary trajectory of a pointed ellipse in the vertical direction depending on the position of 3, and a pendulum motion is given by the motor 2 in a direction orthogonal to the surface of the pointed ellipse. By combining the rotational movement and the pendulum movement, it is possible to give the stirring shaft 15 extremely complex movements in the up-down, left-right, and front-back directions comparable to manual stirring.

Therefore, the stirring shaft moves not only locally, but also over almost the entire area of the object to be stirred, and efficient stirring can be performed.

In addition, it is possible to change the rotation speed of the motor 8, and the radius of the index disk 9, the position of the pin 10 attached to the disk, and the position of the slide bearing 13 can be set arbitrarily. Thereby, the width of the rotational movement of the tip of the stirring shaft 15 can be arbitrarily changed.

In addition to rod-shaped, plate-shaped, claw-shaped stirring shafts, various commonly used stirring blades such as propeller-shaped, paddle-shaped, and turbine-shaped stirring blades can be arbitrarily used in the stirring section.

Note that, without being limited to the above embodiments, as long as the tip of the stirring shaft has a stirring mechanism that combines rotational movement and pendulum movement in a direction orthogonal to the rotating surface, it is within the scope of the present invention. Needless to say, it can be done.

(G) Effect of the invention In the stirring device according to the invention, the position of the stirring shaft moves three-dimensionally with respect to the material to be stirred, and the tip of the stirring shaft moves in a peculiar manner with respect to the rotational speed of the indexing disk 9. It has a high speed, it is possible to effectively stir the material to be stirred, and it is possible to prevent uneven stirring and mixing with a small stirring power.

Furthermore, the device of the present invention allows the width of movement of the stirring shaft to be changed arbitrarily by changing the position of the mechanical parts, for example, by changing the position of the slide pin of the index disk, the position of the slide bearing, or the length of the arm. In addition to this, of course, by changing the rotational speed of the motor, the moving speed of the stirring shaft can also be changed arbitrarily.

By using the device of the present invention as an agitation device for a dyeing test device or a chemical treatment device, a fiber sample made of cotton, yarn, or knitted fabric can be effectively agitated in the treatment bath, thereby eliminating wrinkles in the sample. It is possible to prevent dyeing spots or processing spots, as well as prevent deterioration of texture, and to perform sophisticated processing.

It goes without saying that the apparatus of the present invention can process a plurality of objects to be stirred at once by using a stirring device provided with a plurality of stirring shafts.

Furthermore, the device of the present invention can be easily made larger or smaller and has an excellent stirring mechanism, so it can be widely used as a stirring device in all fields. In particular, when stirring fiber pieces, membrane-like materials, nodules, etc. in a liquid, it is possible to effectively stir the sample without causing any tangles or entanglements.
