Description

  The present invention relates to an animal ear tag attached to an ear shell of an animal such as a cow, pig, or sheep.

  In order to graze, fatten and dairy livestock, it is necessary to identify each animal individually, and ear tags are used to identify the presence or absence of vaccination.

  In the ear mark, a number or the like for identifying the individual is simply displayed on the surface of the plate-shaped tag, or the identification information of the individual is recorded on an electronic information recording medium such as an IC chip attached to the plate-shaped tag. Is recorded, and an individual is identified by reading the recorded identification information by wireless communication.

  As shown in FIG. 15 and FIG. 16 in Patent Document 1 below, the number is printed on the tag of the plate 5, and the IC 6 a in which the identification information of the individual is recorded on the tag of the plate 5 and the transmission or reception of the identification information A coil 6b serving as an antenna is mounted, and an umbrella-like puncture portion 9 at the tip of a male pin 8 formed on the disk portion 7 is fitted into a through hole 5a provided at one end of the plate 5 from the back side of the livestock auricle. Thus, an ear tag for holding the tag of the plate 5 is shown.

JP 2003-70372 A (Electronic ear tag)

  Although the said patent document 1 equips the plate 5 with the coil 6b used as the antenna for transmission or reception of information or identification information, such as identification number and IC6a, since the whole ear tag becomes large by presence of the plate 5, There is a problem that livestock with relatively large ear shells such as cows has no problem, but livestock with relatively small ear shells such as pigs has a burden on the ear shell.

  Furthermore, since the tag of the plate 5 is rotatable, it is possible that the pinna of the livestock will slide and the skin of the pinna will be inflamed. There was a risk of serious lacerations to the pinna by biting and tearing.

  An object of the present invention is an ear tag for resolving the disadvantages of the conventional example and for identifying an animal individual by wireless communication, and it is not necessary to increase the overall size. Therefore, it is suitable for an animal having a relatively small ear shell. An object of the present invention is to provide an animal ear tag that can be used and can prevent an animal from severely tearing the pinna caused by gnawing or hooking.

  In order to achieve the above-mentioned object, the present invention according to claim 1 is characterized in that the tip portion of the core that penetrates the ear shell of the animal has a hook-shaped portion and the first flange as a retaining member is provided at the rear portion. A combination of an animal ear specimen provided and a fastener provided with a hook hole into which the hook-like portion is fitted, and a second flange located on the opposite side of the first flange; Both the first flange and the second flange have an abutting edge to the animal ear shell in the shape of a dish or a bowl, and the first flange and the second flange abut on the animal ear shell. The edges are of substantially the same size, and the contact edges of both the first flange and the second flange are not continuous, such as by providing notches, and an antenna is attached to the animal ear specimen. The gist of embedding a connected electronic information recording medium A.

  According to the first aspect of the present invention, there is no tag as a plate, and the whole is small. Also. The first flange and the second flange are both dish-shaped or bowl-shaped, and when the ear tag is attached to the animal, the contact edge which is the peripheral edge of the flange is in the state that the dish or the bowl is turned down. Therefore, it is possible to prevent the ear mark from falling off due to the animal biting the peripheral end of the flange that has spread outward.

  In addition, by embedding an electronic information recording medium having an antenna connected to the animal ear specimen, individual information of livestock, for example, livestock number or physical information, is recorded in the IC. The individual information of the animal can be recorded on the electronic information recording medium.

Furthermore, the first flange and the second flange are combined with each other so as to sandwich the animal's ear shell, and can be made more difficult to come off.

  Moreover, since the blood vessel of the ear shell is not compressed in the portion where the portion in contact with the ear shell of the animal is discontinuous, it is possible to maintain a good blood circulation of the ear shell even when the ear tag is worn. Therefore, it is possible to prevent skin necrosis caused by the ear mark pressing the ear shell of the animal.

  The gist of the present invention is that the electronic information recording medium connected with the antenna is embedded in the first flange.

  According to the second aspect of the present invention, even when an external antenna is connected to the electronic information recording medium, the electronic information recording medium can be stably stored in a relatively wide portion.

According to a third aspect of the invention, an electronic information recording medium connecting the antenna, as well as embedded in the lance portion, and easily break when a force in a direction to pull out the該槍shaped portion, reconnect non break easily The gist is that the portion is formed on the rear end side of the core rod with respect to the electronic information recording medium.

  According to the third aspect of the present invention, not only when the core rod is cut and the ear tag is removed, but also when the core tag is pulled out and removed, the core rod is cut off at the easy-to-break portion so that the tip end The hook-shaped part remains in the state of being hooked on the fastener. That is, the electronic information recording medium provided in the hook-like portion remains in the fastener. Further, the disconnected portion cannot be reconnected, and it becomes more difficult to reuse the earmark than in the past. In addition, since the electronic information recording medium is provided not in the tag but in the bowl-shaped portion, the tag becomes unnecessary, and an ear tag with less burden can be provided even for an animal having a small ear shell.

  According to a fourth aspect of the present invention, the diameter of a part of the core rod is reduced, the material is switched in the extending direction of the core rod, or the hook-shaped portion is formed differently from the core rod, and the hook The easy-to-break portion is formed by selecting any one or two or more of the joints formed by engaging the concave and convex portions that are meshed with each other in the radial direction with materials having different strengths. Is a summary.

  According to the fourth aspect of the present invention, the easy-to-break portion can be easily formed, and a great deal of labor and cost are not required for manufacturing the ear tag.

  The gist of the invention described in claim 5 is that a battery is provided in the first flange, and the battery and the electronic information recording medium are connected by the antenna.

  According to the fifth aspect of the present invention, the electrical energy for transmitting information from the electronic information recording medium is obtained not only by the antenna receiving the radio wave but also from the battery. Distance communication is possible. In addition, since the battery is provided in the first flange, the usability of the ear mark is not deteriorated due to the presence of the battery.

  The gist of the invention of claim 6 is to use a wireless automatic recognition IC chip incorporating an antenna as the electronic information recording medium.

  According to the seventh aspect of the present invention, since the wireless automatic recognition IC chip incorporating the antenna is used, it is not necessary to separately attach the antenna to the electronic information recording medium, and the labor required for creating the ear mark can be reduced.

  In addition, if this wireless automatic recognition IC chip with a built-in antenna is provided at the front end side of the bowl-shaped part, it becomes easy to bring the reading device closer to the wireless automatic recognition IC chip when reading electronic information, improving communication performance. Can be made.

  The animal ear tag of the present invention is an ear tag for identifying an animal individual by wireless communication, and does not need to be enlarged as a whole. Therefore, the animal ear tag can be suitably used for an animal with a relatively small ear shell, It is possible to prevent the pinna from being severely lacerated by biting or hooking.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a longitudinal side view showing a first embodiment of an animal ear tag of the present invention, FIG. 2 is a side view of the same, and the ear mark is a hook-like portion 12 at the tip of a core rod 10 that penetrates the ear shell of the animal. And an animal ear specimen 1 provided with a first flange 13 as a retaining member at the rear, a latching hole 22 into which the hook-shaped part 12 is fitted, and opposite to the first flange. It consists of the combination with the fastener 2 which formed the 2nd flange 21 located in the side. Note that both the animal ear specimen 1 and the fastener 2 are formed of a non-conductive material such as a synthetic resin that does not inhibit transmission and reception of radio waves.

  As shown in FIG. 4, the first flange 13 includes an elliptical plate body 25 in which the rear portion of the core core 10 is expanded in the orthogonal direction, and a thick elliptical plate body 26 on which the plate bodies 25 are overlapped. The groove 27 is formed in the plate body 26, and the wireless automatic recognition IC chip 15 as an RFID tag is accommodated therein as an electronic information recording medium.

  As the wireless automatic recognition IC chip 15, for example, a non-contact IC chip (trade name “Muchip”, manufactured by Hitachi, Ltd.) is used. The mu chip has both an external antenna and an antenna built-in type, and either one may be used. In this embodiment, the mu chip has an external antenna. The wireless automatic recognition IC chip 15 may be an I / CODE chip manufactured by Flipps.

  The mu chip manufactured by Hitachi, Ltd. is 0.4 mm square, and as shown in FIG. 8, there is an ID storage circuit for a communication circuit, a readout circuit, a header, an identifier, and application data (128 bits). In the figure, reference numeral 15a denotes an external antenna. Then, the wireless automatic recognition IC chip 15 may be fixed with a resin or the like when being accommodated in the groove 27.

  The plate body 25 and the plate body 26 are strengthened by the fitting of the protrusions 28 and the recesses 29, and the core 10 of the plate body 25 penetrates the plate body 26 and protrudes to the opposite side.

  Further, the plate body 26 is formed in a plate shape having an edge piece formed in the periphery, and the first flange 13 composed of the plate body 26 and the plate body 25 has a contact edge 30 to the animal ear shell. .

  The fastener 2 has a second flange 21 as a rod-like body and a peripheral edge which is a contact edge 30 to the animal's ear shell, and the hooking hole 22 is formed by a cylindrical body located in the center. The body is provided with a narrow portion 32 on the inner peripheral surface that engages with a constricted portion 31 formed immediately below the flange-shaped portion 12 of the core rod 10.

  The contact edge portions 30 of both the first flange 13 and the second flange 21 are preferably discontinuous by providing a notch 16 or the like. By doing in this way, since the contact edge part 30 does not press an ear shell in the part of the notch 16, and the blood flow does not worsen, the necrosis of the skin of an ear shell can be prevented.

  The first flange 13 and the second flange 21 have an abutting edge 30 on the animal's ear shell that is substantially the same size. In this way, the animal ear specimen 1 and the fastener 2 When the animal ear specimen 1 is inserted into the fastener 2 with the animal ear shell sandwiched between the core ears 10, the core hook 10 is engaged with the ear shell while penetrating the animal ear shell, The shaped part 12 is received in the retaining hole 22.

  The wireless auto-recognition IC chip 15 is used for production / distribution management of livestock. The feed content, disease, brand, presence / absence of SPF, presence / absence of medication, movement in trading, etc. are input to the reader side. It can be read with the provided antenna.

  When the animal ear specimen 1 and the fastener 2 are forcibly separated, the weak portion is provided so that the first flange 13 is broken and the external antenna 15a or the wireless automatic recognition IC chip 15 is broken. You may do it. This weak part is formed as a thin part.

  FIG. 9 shows a second embodiment of the present invention, which is a muchip with a built-in wireless automatic recognition IC chip 15 antenna which is an RFID tag as an electronic information recording medium. It was stored in the bowl-shaped part 12.

  The wireless automatic recognition IC chip 15 can be embedded in the bowl-shaped portion 12 by any means, such as by forming a hole or hollow, or by embedding the bowl-shaped portion 12 during molding.

  Furthermore, by easily reducing the diameter of a part of the core rod 10, the easily breakable portion 11 is formed as a constricted portion. For example, a member having a cross-sectional shape shown in the figure is formed on the left and right sides, and the wireless automatic recognition IC chip 15 is placed on the distal end side of the portion that becomes the hook-shaped portion 12 to bond the cross-sections of both members.

  On the other hand, when the fastener 2 of the animal ear tag 1 is engaged with the animal ear specimen 1, the inside of the protective case 20 is placed in the fitting space 24 of the hook-like part 12 at a position covering the tip of the hook-like part 12. Formed as. An insertion hooking hole 22 of the hook-shaped portion 12 is provided in a second flange 21 located on the opposite side of the first flange across the animal ear shell, and communicates with the fitting space 24. The retaining hole 22 is formed to be slightly larger than the diameter of the core rod 10 and smaller than the diameter of the bottom portion of the collar-shaped portion 12 so that the collar-shaped portion 12 can be securely latched.

  In this embodiment, both the animal ear specimen 1 and the fastener 2 are formed of a nonconductive material such as a synthetic resin that does not inhibit transmission and reception of radio waves. Further, the thickness of the protective case 20 where the tip of the bowl-shaped portion 12 is located is set to a thickness that does not hinder reading of the wireless automatic recognition IC chip.

  Now, when the animal ear specimen 1 is inserted in the direction of arrow A with respect to the fastener 2 in a state where the animal ear shell is sandwiched between the animal ear specimen 1 and the fastener 2, it is shown in FIG. As described above, the core hook 10 is engaged with the ear shell 3 in a state of passing through the ear shell 3 of the animal, and the hook-shaped portion 12 is accommodated in the protective case 20. When inserting in this way, the easy-to-break part 11 has a smaller diameter than the other parts of the core core 10, so the compression rate in the insertion direction is relatively large, but the core core 10 will not disconnect, There is no effect on the insertion action.

  As described above, when the antenna 4 of the information reading device of the wireless automatic recognition IC chip 15 is brought close to the front surface of the protective case 20 with the animal ear specimen 1 engaged with the fastener 2, the wireless automatic recognition IC is obtained. Since the chip 15 is located on the front end side of the bowl-shaped portion 12, the antenna 4 of the reading device can be brought close to the wireless automatic recognition IC chip 15, and information can be read smoothly.

  Here, when a force is applied in the direction of arrow B in FIG. 10 in order to pull out the animal ear specimen 1 from the fastener 2, a force is applied so as to stretch the core rod 10. Since it is smaller than this part, it is relatively weak against the force in the stretching direction and breaks as shown in FIG. At this time, the hook-shaped portion 12 remains hooked on the fastener 2 and it becomes difficult to take out the wireless automatic recognition IC chip 15 provided in the hook-shaped portion 12. Reuse becomes more difficult.

  The disconnection easy part 11 can also be configured by the following method. For example, as shown in FIG. 12 (a), if the material is changed between the front end side and the rear end side with the breakable portion 11 as a boundary, the core of the animal ear specimen 1 is pulled at the boundary surface when the animal ear specimen 1 is pulled. 10 becomes easy to separate.

  Further, as shown in FIG. 12 (b), the hook-shaped portion 12 is formed differently from the core rod 10, and the enlarged diameter portion 17 a is formed at the tip of the core rod 10, which is larger than the diameter of the core rod 10. A space portion 17c having an opening 17b having a diameter smaller than the diameter of the enlarged diameter portion 17a and capable of accommodating the enlarged diameter portion 17a is formed on the bottom surface side of the bowl-shaped portion 12, and the enlarged diameter portion 17a is formed in the space portion 17c. The animal ear specimen 1 may be housed. The periphery of the opening 17b and the enlarged diameter portion 17a are formed of materials having different strengths. At this time, the periphery of the opening 17b and the enlarged diameter portion 17a protrude and mesh with each other in the radial direction. However, since they have different strengths from each other, if a force is applied in the direction of pulling out the flange portion 12, the strength is increased. The stronger one will break the weaker one. If either one of the periphery of the opening 17b and the enlarged diameter portion 17a is broken, the hooked portion 12 and the core rod 10 are separated.

  In this way, the hook-shaped portion 12 is formed differently from the core rod 10, and the concave and convex portions in which the hook-shaped portion 12 and the core rod 10 mesh with each other in the radial direction are formed of materials having different strengths and meshed. Can also be formed in a screw structure as shown in FIG. For example, the core rod 10 side may be screwed with a male screw and the hook-shaped portion 12 side with a female screw, or the male thread side may be cut with a thread 18 and the other made of a material having a lower strength than the male screw. Thus, only the screw hole may be formed without cutting the screw thread. Also in this case, when a force is applied in the direction in which the hook-shaped portion 12 is pulled out, the screw thread having the lower strength is broken and the hook-shaped portion 12 and the core rod 10 are separated.

  Moreover, as shown in FIG. 13, while connecting the external antenna 15a to the wireless automatic recognition IC chip 15 which does not incorporate an antenna, the battery 19 can be inserted into the first flange 13 and connected to the external antenna 15a. . When the external antenna 15a is used, the communication distance is longer than that of the built-in antenna type, and power is supplied from the battery 19 to the wireless automatic recognition IC chip 15 via the external antenna 15a. Can be stretched.

  When a solar cell is used as the battery 19, the flange 13 where the battery 19 is located is formed of a transparent material, and when used, the animal's light-receiving surface is positioned upward. Attach animal ear tags to the ear shell.

  Furthermore, as shown in FIGS. 9 to 13, the first and second flanges 13, 21 are extended at the outer peripheral ends and bent in the direction of the ear shell when attached to the animal ear shell, Second bent portions 14 and 23 are formed. As a result, both the first flange 13 and the second flange 21 have a plate-like shape or a bowl-like shape with a contact edge 30 to the animal's ear shell, and the animal bites the ends of the flanges 13 and 21. Therefore, it is possible to prevent the ear tag from being gnawed.

  Further, as shown in FIG. 14, the first and second bent portions 14 and 23 are discontinuous by providing a notch 16 on a surface that contacts the animal's ear shell. By doing so, the first and second bent portions 14 and 23 do not press the ear shell at the notch 16 portion, and blood flow does not deteriorate, thereby preventing necrosis of the skin of the ear shell. I can do it. Of the first and second bent portions 14 and 23, the bent portions 14 and 23 are highly elastic so that the portions other than the notch 16 do not strongly press the ear shells at the portions that contact the animal ear shells. It is preferable to form with a material.
