Description

  The present invention relates to an animal identification ear tag wearer that wears ear tags mainly used for individual identification of animals and the like. More specifically, the grip force at the time of ear mark wearing is greatly reduced after a small grip stroke. The present invention relates to a wearing device for an animal identification ear tag.

Current ear tags distributed to livestock animals, for example, farmers in the country for individual identification of cattle, require equipment for wearing the ear tags.
At the beginning of the distribution of the ear tag, there was a need to urgently carry out individual identification management of cattle in connection with BSE (Bovine Spongeformopathy: Japanese name: bovine spongiform encephalopathy). There is a history of collecting ear tags from around the world and distributing them to farmers all over the country, with no need to conduct research and development to make them suitable for use in Japan.
Therefore, each farmer, etc. across the country is distributed to each farmer with an earmark wearer that is made in a foreign country and can only be worn with a specific earmark. In addition, compatibility with each ear tag wearer is an essential requirement.
The distribution management of ear tags is also very complicated, but the problem that the grip part is too wide and difficult to use because the ear tag wearer is also made in foreign countries has been emerging. Recently, many female farmers with small hands and weak power have entered the livestock farms including livestock including cattle, and many have heard that they are struggling to handle foreign-made ear tag wearers. It is becoming

  The technique described in “Patent Document 1” is a technique related to one ear tag wearing device among the above-mentioned foreign-made ear tag wearing devices distributed in Japan. The first and second handle parts that move the jaw part and each jaw part in the direction of drawing each other are basically pivoted about the pivot axis, and the first jaw part and the first handle part are released. This is a technique of an ear tag wearing device (described as “ear tag mounting tool” in the publication) having a structure in which the first jaw portion returns instantaneously at the moment when the ear tag is driven into the cow ear or the like by connecting with the structure.

“Patent Document 2” discloses a technique obtained by improving the technique of “Patent Document 1”.
In this technology, instead of the release structure of “Patent Document 1”, the link member and the second link are connected by a pivot shaft, and these links are extended to a state almost close to a straight line. The first and second jaws corresponding to the jaw members referred to in “Patent Document 1” are maintained by setting the state of each link to a state where it does not bend further inward from the “<” shape. The parts are pivoted in the direction to draw each other, and at the moment when the ear tag is driven into the cow's ear etc., the pivoting shaft part is forced to return beyond the thought point by the control member. The link is made into a "<" shape, and the jaw portion is returned instantly.

The prior art disclosed in “Patent Document 1” is such that the first jaw portion returns instantaneously at the moment when the ear tag is driven into the cow ear or the like, and is described in “Patent Document 2”. The prior art replaces the release structure of “Patent Document 1” with a link mechanism, and none of the above prior arts relieve the gripping force when the ear tag is worn.
In particular, the technology described in “Patent Document 1” is the above-described foreign-made ear tag wearer itself distributed in the current Japan as described above.
When the ear tag is actually attached to the cow's ear or the like, the ear tag wearing device according to the technique described in “Patent Document 1” can be evaluated from the viewpoint of protection of the cow's ear or the like, but it has a large grip force and a wide grip. Many of the above-mentioned opinions have been heard that it is difficult for Japanese women to handle because of the need for width.

Each ear tag applicator currently distributed to farmers all over Japan is composed of a force point, a fulcrum, and an action point, as the pair of ear tag attachment parts and the handle part are crossed at the fulcrum position like a spear. It is the principle of “lever”, and if the action force is increased, the handle portion inevitably requires a long distance, and the grip width of the handle portion is greatly widened.
Just in case, in order to confirm the above opinions from a technical point of view, the distance between the power point-fulcrum and the distance between the fulcrum-action point of each of the ear tag wearers was measured. The length ratio between the force point and the action point is the point of action at all the ear tag wearers with respect to the force point 1, including the ear tag wearer manufactured by the technique described in “Patent Document 1”. It was about 0.52 to 0.60, and it was found that a gripping force that is 1/2 or more of the insertion force (force at the point of action) generated when the male shape ear tag is attached to the female shape ear tag is required. .
Especially in the severe winter season, it seems that it is apparent that the earmarker wearer is having trouble dealing with the earmark when the insertion force increases several times that at room temperature, which supports the above opinions. As a result.

Moreover, as represented by the ear tag mounting device manufactured by the technique described in “Patent Document 1”, the pin that supports the male shape ear tag from the inside is the pin of the male shape ear tag by the ear mark manufacturer. Since the hole into which is inserted is different and has a special shape due to the necessity of devising to reduce the force of pulling out the pin from the male-shaped ear tag after the ear tag is mounted, it can be used only for a specific ear tag . Therefore, in order to use other ear tags, there is a problem that another ear tag wearing device must be prepared.
In addition, it is necessary to make small the force which pulls out the said pin from a male shape ear tag mentioned above, and also considers the force which pulls out the said pin from a male shape ear tag in addition to the return spring of a handle part. This is because if the force required to pull out the pin is large, it is necessary to further strengthen the return spring, and this force has a great influence on the gripping force of the handle.

Therefore, the present invention can handle even a woman with a small hand and a weak force by making the gripping force remarkably relieved even if the gripping stroke when the earmarker is worn is reduced. The primary object is to provide a wearer for animal identification ear tags.
A second object of the present invention is to provide a device for attaching an animal identification ear tag that allows a plurality of types of ear tag mounting to be performed with one ear tag mounting device.

In order to achieve the above object, the present invention solves the problem by using the following means.
The first problem-solving means is a wearer for an animal identification ear tag composed of a male-shaped ear tag and a female-shaped ear tag into which the male-shaped ear tag is fitted, wherein the male-shaped ear tag and the female shape While providing a basic case that integrally forms a first ear tag mounting portion for mounting one of the ear tags and a fixed handle portion having a grip portion located behind the first ear tag mounting portion. The male-shaped ear tag and the female-shaped ear mark that are opposed to the first ear-mark mounting portion with the basic case at an intermediate position between the first ear-mark mounting portion and the fixed handle portion as a main pivot point. A second ear tag mounting portion for mounting the other ear tag, and the movable handle portion sharing the main pivot point of the second ear tag mounting portion and having a grip portion. Are arranged so as to face each other with an interval between them and the movable handle portion. Serial and a second ear tag mounting portion, linked via a modified toggle mechanism having a power transmission mechanism, a deformation toggle mechanism with said power transmission mechanism, and the male-shaped ear tags and the female shape ear tags Provided is a mounting device for an animal identification ear tag arranged so as to obtain a posture capable of obtaining a working force close to the maximum at the rotational position of the second ear tag mounting portion that requires a substantially maximum insertion force when fitted. .

The second problem-solving means is a mounting device for an animal identification ear tag composed of a male-shaped ear tag and a female-shaped ear tag into which the male-shaped ear tag is fitted, wherein the male-shaped ear tag and the female shape While providing a basic case that integrally forms a first ear tag mounting portion for mounting one of the ear tags and a fixed handle portion having a grip portion located behind the first ear tag mounting portion. The male-shaped ear tag and the female-shaped ear mark that are opposed to the first ear-mark mounting portion with the basic case at an intermediate position between the first ear-mark mounting portion and the fixed handle portion as a main pivot point. A second ear tag mounting portion for mounting the other ear tag, and the movable handle portion sharing the main pivot point of the second ear tag mounting portion and having a grip portion. Are arranged so as to face each other with an interval between them and the movable handle portion. Serial and a second ear tag mounting portion, linked via a modified toggle mechanism having a power transmission mechanism, a deformation toggle mechanism with said power transmission mechanism, and the male-shaped ear tags and the female shape ear tags When fitting, it is arranged so as to obtain a posture that can obtain a working force close to the maximum at the rotation position of the second ear tag mounting portion that requires a substantially maximum insertion force, and further, the first ear tag mounting portion or ear tags mounting portion of any one mounting the male shape ear tag of the second ear tag mounting portion, the cantilever pin supporting the male shape ear tags from the inside is provided, of the cantilever pin-shaped There is provided an animal identification ear tag wearing device having at least a part of which has a tapered shape with a thick root portion and a thin tip portion.

A third problem solving means includes, in addition to any one of the first problem solving means and the second problem solving means, the deformation toggle mechanism, and the fixed handle portion with the main pivot point of the basic case as a boundary. A first link pivoted at one end on the basic case at a position eccentric to the opposite side, and the second link shorter than the first link with the other end of the first link as a pivot position. Provided is a device for attaching an animal identification ear tag including a second link connecting an ear tag mounting unit .

Fourth means for solving the problem, in addition to the third problem solving hand stage, the power transmission mechanism is on the movable handle portion of the grip portion side opposite to said main pivot point of the movable handle portion as a boundary a portion located to provide a mounting device of the second link the pivot position direction towards said animal identification ear tags to the site of the first link coupled power transmission from pivot position of the first link.

The fifth problem solving means includes, in addition to any one of the third problem solving means or the fourth problem solving means, a virtual straight line between the pivot position of the first link and the pivot position of the second link. If, provide a mounting device for animal identification ear tags for the crossing angle of the virtual straight line and the acute angle between the connection points for connecting the second ear tag mounting portion of the second link of the pivot position Toko of said second link To do.

The sixth problem solving means includes a virtual straight line between the pivot position of the first link and the pivot position of the second link in addition to any one of the third and fifth problem solving means. When, with the crossing angle of the virtual straight line between the connection points for connecting the second ear tag mounting portion of the second link of the pivot position Toko of the second link at an acute angle, the acting force of the maximum wherein said first link in the resulting position the intersection angle between the second link is to provide a mounting device for animal identification ear tags, which was not allowed to exceed change point.

Seventh problem solving means includes, in addition to any one of the second problem solving means or the sixth problem solving means, the male shape in the first ear tag mounting part or the second ear tag mounting part. When fixing the cantilever pin that supports the male-shaped ear tag from the inside to any one of the ear tag attachment parts to which the ear tag is to be attached, the base side of the cantilever pin is rotated in the escape direction of the animal to be identified. A wearer for animal identification ear tags attached to move is provided.

The operational effect of the first problem solving means is that the movable handle portion and the second ear tag mounting portion are connected via a deformation toggle mechanism having a power transmission mechanism, and the deformation toggle having this power transmission mechanism is provided. the machine configuration, when fitting the male shape ear tags and female shape ear tag, the position where the maximum near the acting force is obtained in the rotational position of the second ear tags mounting unit that requires near maximum fitting force Arranged .
Therefore, in the second ear tag mounting portion, the front and back of the animal's ear to male shape ear tags and female shape ear tags reaches the rotational torque becomes large rotation speed of the second ear tags attached portion larger However, when the male and female ear tags reach the front and back of the animal's ears, the rotational torque increases as the rotation speed of the second ear tag mounting part decreases, Since the rotational torque is significantly increased in the vicinity of the female shape ear tag, by utilizing this significantly increased rotational torque, the movable handle portion has a strong force with a small rotation angle and a gripping force. It is possible to amplify the movement at the time of power transmission of the deformation toggle mechanism provided with the power transmission mechanism so as to be transmitted to the second ear tag mounting portion.
This is because, in the vicinity where the male ear tag is fitted into the female ear tag, the rotational torque at the rotation fulcrum position (main pivot point) of the second ear tag mounting part is significantly increased compared to the conventional ear tag mounting device. Therefore, even if a part of the rotational torque is utilized in the power transmission mechanism, a rotational torque larger than that of the conventional ear tag mounting device can be obtained at the rotation fulcrum position of the second ear tag mounting unit. .
In other words, the maximum grip width between the movable handle part and the fixed handle part is narrowed, and the movement of the movable handle part whose rotation angle is reduced by gripping is attached to the second ear tag via a deformation toggle mechanism equipped with a power transmission mechanism. This means that the rotational torque at the rotation fulcrum position of the second ear tag mounting portion can be made larger than that of the conventional ear tag mounting device even if the rotation angle of the portion is amplified.
As a result, the movable handle that serves as the power point does not require a large force until either the male-shaped ear tag or the female-shaped ear tag reaches the animal's ear. Ki out that priority is given to the moving speed, or, later, in the middle of the male shape ear tags from entering the eating write only female shape ear tag to the animal's ear, but very large action force is generated, is the emphasis moving Only a small reaction force is transmitted to the handle portion.
In other words, in the movable handle portion, the rotational speed of the movable handle portion increases until either the male or female ear tag reaches the animal's ear, and the male ear tag is placed on the animal's ear. is, although the rotation speed of the movable handle portion is reduced, so that you can also transmit a strong force to the second ear tags attached unit is a working point with a small gripping force when the coalesce and are inserted female shape ear tag .
As described above, the ear handle can be attached with a small gripping force without extending the width of the grip portion by lengthening the handle portion like the conventional ear tag wearer. As a result, there is an effect that it is possible to provide a wearer of an animal identification ear tag that can be handled even by a woman whose hand is small and weak.

Above, function and effect of the second problem solving means, a movable handle portion and the second ear tag mounting portion, linked via a modified toggle mechanism having a power transmission mechanism, the deformation toggle Organization, male shape when fitting the ear tags and female shape ear tag, arranged to run in posture obtained up to near the acting force rotational position of the second ear tags mounting unit that requires near maximum fitting force. Therefore, in the second ear tag mounting part, the rotational speed of the second ear tag mounting part increases and the rotational torque does not increase until the male and female ear tags reach the front and back of the animal's ear. When the male and female ear tags reach the front and back of the animal's ears, the rotational torque increases as the rotation speed of the second ear mark mounting portion decreases, and the male ear mark becomes female. In the vicinity where the ear tag is fitted, the rotational torque becomes remarkably large. Therefore, by utilizing this remarkably large rotational torque, the movable handle portion is applied with a strong force with a small rotational angle and a gripping force. It is possible to amplify the movement at the time of power transmission of the deformation toggle mechanism provided with the power transmission mechanism so as to be transmitted to the ear tag mounting portion.
This is because, in the vicinity where the male ear tag is fitted into the female ear tag, the rotational torque at the rotation fulcrum position (main pivot point) of the second ear tag mounting part is significantly increased compared to the conventional ear tag mounting device. Therefore, even if a part of the rotational torque is utilized in the power transmission mechanism, a rotational torque larger than that of the conventional ear tag mounting device can be obtained at the rotation fulcrum position of the second ear tag mounting unit. .
In other words, the maximum grip width between the movable handle part and the fixed handle part is narrowed, and the movement of the movable handle part whose rotation angle is reduced by gripping is attached to the second ear tag via a deformation toggle mechanism equipped with a power transmission mechanism. This means that the rotational torque at the rotation fulcrum position of the second ear tag mounting portion can be made larger than that of the conventional ear tag mounting device even if the rotation angle of the portion is amplified.
As a result, the movable handle that serves as the power point does not require a large force until either the male-shaped ear tag or the female-shaped ear tag reaches the animal's ear. Ki out that priority is given to the moving speed, or, later, in the middle of the male shape ear tags from entering the eating write only female shape ear tag to the animal's ear, but very large action force is generated, is the emphasis moving Only a small reaction force is transmitted to the handle portion.
In other words, in the movable handle portion, the rotational speed of the movable handle portion increases until either the male or female ear tag reaches the animal's ear, and the male ear tag is placed on the animal's ear. is, although the rotation speed of the movable handle portion is reduced, so that you can also transmit a strong force to the second ear tags attached unit is a working point with a small gripping force when the coalesce and are inserted female shape ear tag .
As described above, the ear handle can be attached with a small gripping force without extending the width of the grip portion by lengthening the handle portion like the conventional ear tag wearer. As a result, there is an effect that it is possible to provide a wearer of an animal identification ear tag that can be handled even by a woman whose hand is small and weak.
Furthermore, a cantilever pin for supporting the male shape ear tag from the inner side is provided in any one ear mark mounting portion to which the male shape ear tag is attached, and at least a part of the cantilever pin shape is thick at the base portion side at the tip portion. By adopting a tapered shape on the side, it is possible to cope with the insertion part of the cantilever pin of the male shape ear tag which varies depending on the manufacturer of the ear tag. This may be due to the situation where the cantilever pin is difficult to be removed from the male shape ear tag where the cantilever pin and the male shape ear mark insertion portion are tightly fitted depending on the ear tag. Because the return force is extremely large, it means that the separation force between the second ear tag mounting part and the first ear tag mounting part is large, and it is easy even if the cantilever pin and the insertion part of the male ear tag are tightly fitted The cantilever pin can be pulled away from the ear tag.
That is, it is possible to achieve the second object of providing an animal identification ear tag mounting device that enables mounting of various types of ear tags with one ear tag mounting device.

The effect of the third problem solving means is that the deformation toggle mechanism is configured and arranged with the minimum number of parts , so that the entire ear tag mounting device can be made inexpensive and compact, and it is easy for women to handle. There is an effect that it is possible to provide a wearer for an identification ear tag.

  The operational effect of the fourth problem solving means is that the operating directions of the second ear tag mounting portion and the movable handle portion are reversed, in other words, the second earpiece is rotated in the direction of gripping the movable handle portion. Since the ear tag mounting portion rotates toward the first ear tag mounting portion side, it can be handled in the same manner as a conventional ear tag mounting device, and can be handled without a sense of incongruity for the operator.

The function and effect of the fifth problem solving means will be described as follows.
That is, F is the force in the rotational direction of the first link at the pivot position of the second link, P is the force acting in the longitudinal direction of the second link, and the pivot position of the first link and the pivot of the second link. When the crossing angle α of the virtual straight line between the connection points connecting the virtual straight line between the positions, the pivot support position of the second link and the second ear tag mounting portion of the second link is P = F / sin α Since the equation holds, the fact that the crossing angle is an acute angle means that the smaller the crossing angle is, the more the force acting in the longitudinal direction of the second link is amplified. It will contribute to the achievement of the purpose.

Above, advantageous effects according to the sixth means for solving problems is male shape ear tags and when fitting the female shape ear tags, the maximum in the second ear tags mounting unit rotational position of which almost requires maximum fitting force Since the crossing angle α does not exceed the thought point due to the positional relationship between the first link and the second link in a state where an acting force can be obtained, the return force when the second ear tag wearing part returns to the original position is set. It means you can make it bigger. In other words, even if the second ear tag mounting portion touches an external obstacle, the second ear tag mounting portion quickly leaves the animal, and safety can be ensured.
In addition, being able to increase the return force when the second ear tag mounting part returns to the original position also means that the return force for returning the movable handle part from the ear tag mounting completion position to the original position can be reduced. Therefore, if this return force is performed by a spring, this spring force can be reduced, so that there is an effect that the gripping force when the operator grasps the movable handle portion can be reduced.

The effect of the seventh problem solving means described above is that the root side of the cantilever pin is attached so as to rotate in the escape direction of the identified animal. even to escape, the posture of the cantilever pin by the rotation effect becomes along the escape direction of the animal, without mounting device is skipped animal identification ear tags, the operator can work safely.

  As described above, according to the present invention, it is possible to provide a wearer for animal identification ear tags that can be handled even by a woman with small hand and weak force, and for attaching various types of ear tags with one animal identification ear tag wearer. In addition to achieving the intended purpose of providing a wearable device for an animal identification ear tag, the above-described effects can be achieved by each aspect.

These show the principal part of the mounting device of the animal identification ear tag of this invention, and are explanatory drawings of the front view which cut | disconnected the exterior part and some mechanism parts in the AA line of FIG. These are top views which show an example of the mounting device of the animal identification ear tag of this invention Is a front view of FIG. FIG. 3 is an enlarged explanatory view of a deformation toggle mechanism having a power transmission mechanism in front view in FIG. FIG. 4 is an enlarged explanatory view of a part of the power transmission mechanism portion of FIG. 1 and a cross-sectional view taken along the line BB of FIG. Is an explanation showing an example of a posture capable of obtaining a working force close to the maximum at the rotation position of the second ear tag mounting portion that requires a substantially maximum insertion force when fitting the male shape ear mark and the female shape ear mark. Figure Is an explanatory view showing an example of the posture of each mechanism at the moment when wearing of the ear tag is completed These are explanatory drawings of a front view corresponding to FIG. 1 showing another embodiment FIG. 2 is a partially cross-sectional perspective view showing an example of an ear tag attached to an animal by the animal identification ear tag wearer of the present invention.

First, an animal identification ear tag to be attached to an animal with the animal identification ear tag attachment device of the present invention will be described.
In FIG. 9, among the animal identification ear tags ET paired with a male shape ear mark 1 and a female shape ear mark 2 into which the male shape ear mark 1 is fitted, the male shape ear mark 1 includes a bill portion 1 a and the tag. The shaft portion 1b extends from a part of the portion 1a, the arrowhead portion 1c provided on the distal end side of the shaft portion 1b, and the pin insertion hole 1d formed near the center of the shaft portion. The pin insertion hole 1d is a bottomed hole into which the cantilever pin 31 of the mounting device T for the animal identification ear tag ET described later is inserted.

  In addition, the female ear tag 2 has a bill portion 2a, a fitting hole 2b provided in a part of the bill portion 2a and having a retaining portion 2c, and an arrowhead storage portion 2d.

The animal identification ear tag ET is properly used depending on the attached animal such as a tag type as shown in FIG. 9 or a round type (not shown), but most of them are the same ear tags recommended by the ear tag manufacturer. The wearer can be used.
Although the animal identification ear tag ET varies in size and shape depending on the ear tag manufacturer, the basic configuration is as described above, and most of the materials are made of resin mainly composed of polyurethane resin. Keep it.

Next, the wearing device of the animal identification ear tag of the present invention will be described.
1 to 5, the animal identification ear tag wearing device T includes a first ear tag mounting unit 11 for mounting one of the male shape ear tag 1 and the female shape ear tag 2, and this A basic case 13 is provided in which a fixed handle portion 12 having a grip portion 12a located behind the first ear tag mounting portion 11 is integrally formed. In addition, the 1st ear tag mounting | wearing part 11 mounts | wears with the female shape ear tag 2 in this Example.

On the distal end side of the first ear tag mounting portion 11, an ear mark presser plate 14 for sandwiching the female ear tag 2 is provided. The ear tag presser plate 14, the first ear tags mounting unit 11 has a swing fulcrum 14c, and ear tags pressing portion 14a of the U-shaped positioned in the first ear tags attached portion 11 distally, rocking fulcrum 14c The presser release piece 14b located on the rear side and a spring 14d that urges the presser release piece from below are formed. That is, since the female-shaped ear tag 2 is sandwiched between the ear mark pressing portion 14a and the distal end portion of the first ear tag mounting portion 11 by the biasing force of the spring 14d, the female ear tag 2 is female even if the tip of the mounting device T is directed downward. It is desirable to set the biasing force of the spring 14d so that the shape ear tag 2 is not displaced by its own weight or the like.

In this embodiment, a U-shaped step groove 11a for receiving the receiving portion 2e of the female ear tag 2 is provided at the tip of the first ear tag mounting portion 11 at a position facing the back side of the ear mark presser portion 14a. . Since the shape of the animal identification ear tag differs depending on the ear tag manufacturer, the corrugated groove 11a has a receiving part 2e shown in FIG. 9 so that the receiving part 2e can be accommodated in the corrugated groove 11a. What is necessary is just to determine the dimension of the step groove 11a, and about the female-shaped ear tag which does not have the receiving part 2e, it should just receive on the upper surface 11b of the step groove 11a.
Further, a boss 2f is formed on the outer peripheral portion of the arrowhead storage portion 2d shown in FIG. 9, and the one corresponding to the boss 2f also includes other ear tags, and therefore includes the one shown in FIG. Since the outer shape of the arrowhead storage part protrudes as a boss in all female-shaped ear tags, the boss storage part is provided in the first ear tag mounting part 11 below the step groove 11a at the tip of the first ear tag mounting part 11. 11c is provided, and due to the presence of the step groove 11a and the boss storage part 11c, it is possible to press the female-shaped ear tags of many animal identification ear tags currently distributed on the first mounting part by the ear mark holding plate 14. I can do it.

  On the other hand, a main pivot point pin 15 serving as a main pivot point is provided in the basic case 13 at an intermediate position between the first ear tag mounting portion 11 and the fixed handle portion 12. The main pivot point pin 15 serves as a pivot point, and the other ear tag of the male shape ear tag 1 and the female shape ear tag 2 facing the first ear mark mounting portion 11 with a space therebetween (in this embodiment, the male ear mark 1 is male). A second ear tag mounting portion 21 for mounting the shape ear tag 1) is provided. 1 and 3, the main pivot fulcrum pin 15 is disposed at the same position as the first ear tag mounting part 11 when the second ear tag mounting part 21 rotates counterclockwise around the main pivot point 15. It is determined to face each other.

In addition, a cantilever pin 31 to be inserted into the pin insertion hole 1 d (FIG. 9) of the male ear tag 1 is disposed on the distal end side of the second ear tag mounting portion 21. The cantilever pin 31 is screwed to the pin mounting portion 31a, and the pin mounting portion 31a includes a pin fixing portion 31c fixed to the distal end side of the second ear tag mounting portion 21 via a spring 31b close to a close winding. It is connected.
Both end portions of the spring 31b are fixed to the pin mounting portion 31a and the pin fixing portion 31c by press contact screwing or brazing.
When the animal escapes when the ear tag is attached, the animal identification ear mark ET is pulled by the movement of the animal. At this time, the cantilever pin 31 is rotated in the middle portion of the spring 31b in the animal escape direction. The male-shaped ear tag 1 can be removed from the cantilever pin 31 by bending to prevent the ear of the animal from being damaged and the cantilever pin 31 from being damaged.
In other words, the posture of the animal identification ear tag ET when wearing a normal ear mark is mounted with the tip facing from the side of the animal to the animal side, so the animal shakes his neck and wears the animal identification ear mark The cantilever pin 31 is devised to bend so as to rotate at least in front of the second ear tag mounting portion 21 because it often escapes away from the container T. Accordingly, the female ear tag 2 also opens the step groove 11a and the boss storage part 11c of the first ear tag mounting part 11 at the front end side of the first ear tag mounting part 11, and the rotation direction of the cantilever pin 31 The female ear tag 2 is removed in the same direction.

On the other hand, the cantilever pin 31 is inserted into the pin insertion hole 1d of the male ear tag 1, and a tapered portion 31d is formed in a part of this pin. The tapered portion 31d is configured so that the male-shaped ear tag 1 bites into the cantilever pin 31 even if the shape and size of the pin insertion hole 1d varies depending on each ear tag manufacturer.
In the present invention, even if the biting force between the cantilever pin 31 and the male-shaped ear tag 1 is increased, an extremely large return force is generated in the mounting device T after the ear tag is mounted, which will be described later. The cantilever pin 31 can be reliably pulled out of the male-shaped ear tag 1 by this large return force without substantially affecting.
In the case of the conventional mounting device, if the return force after the mounting operation is increased, the gripping force at the time of mounting is greatly affected. Therefore, there is a problem that the return force cannot be increased, but the present invention solves this problem.

Next, the movable handle portion 41 side will be described. The main handle fulcrum pin 15 of the second ear tag mounting portion 21 on the basic case 13 is shared, and the movable handle portion 41 having the grip portion 41 a is used as the fixed handle portion 12. It arrange | positions so that a space | interval may be provided and it may oppose.
And the movable handle | steering-wheel part 41 and the 2nd ear tag mounting | wearing part 21 are connected via the deformation | transformation toggle mechanism 51 provided with the power transmission mechanism 61. FIG. This will be described in detail as follows.
The deformable toggle mechanism 51 has a first link pivot pin 51a on one end side on the basic case 13 at a position eccentric to the opposite side of the fixed handle portion 12 with the center of the main pivot point pin 15 of the basic case 13 as a boundary. The first link 51b that pivots, and the second ear tag mounting portion 21 that is shorter than the first link 51b with the second link pivot pin 51c on the other end side of the first link 51b as a pivot position. The second link 51e is connected by a connection pin 51d.
In addition, when the first link 51b and the second link 51e are fitted into the male-shaped ear tag 1 and the female- shaped ear tag 2, the rotation of the second ear tag mounting portion 21 that requires a substantially maximum fitting force. Arrange it so that it is in a posture that allows you to obtain an action force close to the maximum in position.

  Regarding the posture in which when the male-shaped ear tag 1 and the female-shaped ear tag 2 are fitted, a working force close to the maximum can be obtained at the rotational position of the second ear tag mounting portion 21 that requires a substantially maximum fitting force. More specifically, as shown in FIG. 1, it is desirable to determine the arrangement of the first link 51b and the second link 51e of the deformation toggle mechanism 51 before the mounting operation of the mounting device T as follows, It is possible to obtain the above-mentioned “posture capable of obtaining a maximum acting force”.

That is, the angle formed by the deformation toggle mechanism 51 before the mounting operation of the mounting device T, specifically, the center of the first link pivot pin 51a and the pivot position of the second link 51e, which are pivot positions of the first link 51b. A virtual straight line 51f between the centers of a certain second link pivot pin 51c, the center of the second link pivot pin 51c, which is the pivot position of the second link 51e, and the second ear tag mounting portion 21 of the second link 51e In order to determine the angle α (see FIG. 1) formed by the imaginary straight line 51g between the centers of the connecting pins 51d that are connecting points, first, the arrowhead portion 1c of the male-shaped ear tag 1 of the animal identification ear tag ET is determined . When entering the fitting hole 2b of the female ear tag 2, from the position (the portion shown in FIG. 6) that requires the greatest mounting force to the position (the portion shown in FIG. 7) where the arrowhead portion 1c exits the fitting hole 2b. Finding the rotation position of the second ear tag mounting part 21 . As a result, the center position of the connecting pin 51d at the position where the maximum mounting force of the second ear tag mounting portion is required is determined. In this state, if the connecting position of the second link is arranged here, the first link 51b and a second link 51e both virtual straight line 51f, the angle α of 51g becomes small fence. In addition, the center of the connecting pin 51d at the position escaping the arrowhead portion 1c fitting hole 2b is, first link 51b and the virtual line position of the second link 51e so that the position does not exceed the virtual straight line 51f (change point) The angle α formed by 51f and the virtual straight line 51g is adjusted and determined to be the smallest .

Next, the main pivot point pin 15 of the second ear tag mounting part 21 is set as the center of rotation so that the distance between the tip of the cantilever pin 31 and the ear mark holding plate 14a before the mounting operation of the mounting device T is appropriate. Determine the rotation start position. As a result, the position of the connecting pin 51d at the rotation start position is determined. At that position, the virtual circle having the radius of the virtual straight line 51g centered on the axis of the connecting pin 51d and the first link pivot support. If the first link 51b and the second link 51e are connected by the second link pivot pin 51c at the intersection with the virtual circle whose radius is the length of the virtual straight line 51f centered on the axis of the pin 51a, inevitably. The position where the deformation toggle mechanism 51 before the mounting operation of the mounting device T is disposed is determined. At this time, it is desirable that the intersection angle between the virtual straight line 51f and the virtual straight line 51g be an acute angle.
The reason for this is that the force in the rotational direction of the first link 51b at the position of the second link pivot pin 51c of the second link 51e is F and the force acting downward in the longitudinal direction of the second link 51e (on the virtual straight line 51g ) P = F / sinα, where P is the crossing angle between the virtual straight line 51f and the virtual straight line 51g, and it is desirable that the crossing angle be an acute angle. , Sinα is less than 1 and the crossing angle α is smaller than 90 degrees, the force acting in the longitudinal direction of the second link 51e is amplified.
In other words, as shown in FIGS. 6 and 7, the force acting in the downward longitudinal direction of the second link 51e increases remarkably as the crossing angle α decreases to the point near the thought point. When the female ear tag 2 is fitted, a working force close to the maximum can be obtained at the rotation position of the second ear tag mounting portion 21 that requires a substantially maximum fitting force.

Subsequently, the power transmission mechanism 61 provided in the deformation toggle mechanism 51 will be described. As described above, when the male shape ear tag 1 and the female shape ear tag 2 are fitted, the first fitting force that requires a substantially maximum fitting force is required. Since the crossing angle α of the rotation position of the binaural ear mounting portion 21 is reduced to a point close to the thought point (see FIG. 6), the force acting in the downward longitudinal direction of the second link 51e is remarkably increased. The moving force F may be an extremely small power transmission.

Thus, the force F to move the first link 51b is because it is extremely small power transmission, it is desirable stipulated by the following procedure when determining the power transmission mechanism 61.
First, the area between the grip portion 12a of the fixed handle portion 12 and the grip portion 41a of the movable handle portion 41 is determined from the palm size of the Japanese woman, and the position of the movable handle portion 41 before the mounting operation of the mounting device T is determined. .
Next, the power transmission pin 61a is arranged at an appropriate position between the center position of the main pivot point pin 15 and the first link pivot pin 51a .
This is even shorter distance between centers of the first link pivot pin 51a and the power transmission pin 61a is at the position of the connecting pin 51d of the deformation toggle mechanism 51, great power is amplified smaller the angle α In view of this, a sufficiently large force can be transmitted to the cantilever pin 31 without increasing the distance between the centers of the first link pivot pin 51a and the power transmission pin 61a, and a compact power transmission mechanism 61 can be achieved. This is nothing but to turn one link 51b counterclockwise in FIG.
In this embodiment, the power transmission pin 61a is fixed so as to be sandwiched between the two first links 51b as shown in FIG. As shown in detail in FIG. 5, a long groove 41b is provided on the opposite side of the fixed handle portion 12 of the main pivot point pin 15 of the movable handle portion 41, and the power transmission pin 61a is fitted into the long groove 41b.
That is, when the movable handle portion 41 rotates clockwise around the main pivot point pin 15, the first link 51b rotates counterclockwise around the first link pivot pin 51a opposite to the rotation direction of the long groove 41b. The power of the movable handle portion 41 is transmitted to the first link 51b while rotating and the power transmission pin 61a slightly sliding in the long groove.
With such a configuration of the power transmission mechanism 61, as with the conventional mounting device, when the movable handle portion 41 is gripped, the second ear tag mounting portion 21 can be rotated to the first ear tag mounting portion 11 side. Even an operator accustomed to using a conventional mounting device can operate the mounting device T of the present invention without a sense of incongruity.

  Incidentally, when examining the gripping force of the wearer T of this embodiment, for example, in the case of the composition ratio of each figure, the distance from the center of the main pivot point pin 15 to the gripping portion 41a (force point) of the movable handle portion 41 Is 12.5 cm, and when the force applied to the grip portion 41a is 1, the magnification of the force (acting force) applied to the cantilever pin 31 is about 1.4 times in the unloaded state of FIG. The grip of the grip portion 41a, which is the power point, is about 5.5 times in the posture state in which a nearly maximum working force can be obtained at the rotational position of the second ear tag mounting portion 21 that requires a substantially maximum fitting force. In terms of force, a gripping force that is about one-fifth of the insertion force (force at the point of action) generated when the male shape ear tag 1 is attached to the female shape ear tag 2 is sufficient. The gripping force is less than about 1.75th of each wearer. To note that the handle on.

As described above, since a large mounting force can be obtained with a small gripping force, the present invention that can attach an animal ear tag to a cow's ear even for a weak woman means that the return force after mounting can also be increased. .
That is, the aforementioned angle α of the second link 51e with respect to the posture first link 51b of the deformed toggle mechanism 51 after the ear tag is attached is the smallest angle that does not exceed the thought point due to the return force of the spring 61c described later of the first link 51b. Therefore, the return force at the position of the cantilever pin 31 is the most amplified return force.
The taper portion 31d of the cantilever pin 31 is amplified at the position of the cantilever pin 31 even if the pinching hole 1d of the male-shaped ear tag 1 has the biting phenomenon described above due to the difference in shape of each ear tag manufacturer. By means of the return force, this biting phenomenon can be eliminated and the cantilever pin 31 can be pulled out of the male shape ear tag of each manufacturer, and the gripping force of the movable handle part 41 is not affected. doing.
As a result, for the male shape ear tag, the dimension of the step groove 11a is determined so that the receiving portion 2e of the female shape ear mark 2 fits in the step groove 11a of the first ear mark mounting portion, and the receiving portion 2e. The female mounting ear T of the present invention has a female shape ear tag 1 and a female shape ear tag 2 which are slightly different in shape and size by being received by the upper surface 11b of the step groove 11a. There is also an effect that many kinds of ear tags can be worn with the same wearing device without exchanging the cantilever pins.

The spring 61c is a spring stretched between a spring hanger 61d provided between the first link pivot pin 51a and the second link pivot pin 51c of the first link 51b and a spring hanger pin 41d provided on the movable handle portion 41. Thus, the first link is always rotated clockwise, and the movable handle portion 41 is urged to rotate counterclockwise.
If the spring 61c is too soft, it becomes difficult to hold when the movable handle 41 moves due to its own weight or the position of the center of gravity depending on its own weight or the position of the center of gravity. What is necessary is just to determine the intensity | strength in the range which does not have big influence on the grip strength at the time of mounting | wearing.

  Alternatively, as shown in FIG. 8, another auxiliary spring 61d may be additionally provided at the positions shown in FIG. 8 of the fixed handle portion 12 and the movable handle portion 41, and the spring 61c is removed to make only the auxiliary spring 61d. However, the present invention is achieved.

The first link 51b and the main pivot pin 15 are in contact with each other in the state of FIG. 1 (refer to FIG. 4 for details). This is because the tip and the ear of the cantilever pin 31 before the mounting device T is mounted. In determining the rotation start position around the main pivot point 15 of the second ear tag mounting portion 21 so that the distance between the mark holding plates 14a is appropriate, in this embodiment, the first link 51b and the main pivot are determined. The rotation start position of the second ear tag mounting portion 21 is determined by contacting the fulcrum pin 15.
Further, the area between the grip portion 12a of the fixed handle portion 12 and the grip portion 41a of the movable handle portion 41 is obtained from the palm size of the Japanese woman, and the position of the movable handle portion 41 before the mounting operation of the mounting device T is determined. At this time, in this embodiment, a part of the distal end side of the movable handle portion 41 is bulged and brought into contact with the first link pivot pin 51a to serve as a stopper for the movable handle portion 41.

Furthermore, in this embodiment, as shown in FIGS. 1 and 4 to 8, as a measure for restricting the movement of the connecting pin 51d, the second link pivot pin 51c, and the first link pivot pin 51a in the thrust direction, A one-way washer 71a that slides in one direction but locks in the other direction is provided. Further, both ends of the main pivot pin 15 and the first link pivot pin 51a are connected to a cap nut-shaped one-way washer. 71b restricts the movement of each pin in the thrust direction.
This is effective in reducing the number of assembling steps as well as not worrying about loosening because screws are not used.

  As described above, according to the present invention, it is possible to provide a device for attaching an animal identification ear tag that can be handled even by a woman with a small hand and weak force, and it is possible to attach various types of ear tags with a single ear tag wearer. Therefore, in addition to solving the current situation that farmers are struggling with wearing ear tags, the distribution management of cattle individual identification ear tags distributed every year can be simplified. is there.
