Description

  The present invention relates to a strip-shaped ear tag, and in particular, a strip-shaped ear tag that holds a wireless individual identification tag (hereinafter referred to as an RFID tag) and is attached to an ear of a domestic animal such as a cow. About.

  In order to identify livestock such as cows and horses on a ranch or the like, there are known ear tags that are attached by penetrating the ears of livestock. There are 1-piece type and 2-piece type of ear tags, and the 1-piece type is a single piece, and consists of a tag part formed at one end of the shaft part and an anchoring part formed at the other end. The two-piece type is a two-piece object, and is composed of a bill portion (male bill) formed at one end of the shaft portion and a separate bill portion (female bill) attached to the shaft end of the shaft portion. The The ear tag is attached to livestock with the shaft part penetrating the ear shell of the livestock ear, and the tag part is used to identify the livestock individual identification number such as livestock registration number, and livestock on the ranch from a distance. The numbers are enlarged and printed or handwritten. Furthermore, a bar code indicating a livestock individual identification number or a two-dimensional bar code may be printed on the tag part of the ear tag.

  On the other hand, in recent years, the development of RFID systems that incorporate individual RFID tags into ear tags and read individual identification numbers such as animal registration numbers recorded on ear tags using radio has been rapidly increasing in Japan and other countries where livestock is thriving. It is being advanced.

  An RFID system consists of a reader / writer (antenna + decoder + controller) and an RFID tag (microchip + antenna) that can store information in an electronic circuit, and enables automatic individual recognition that enables mutual data communication by wireless communication. Technology. At least one identification symbol is written on the RFID tag. Due to the non-contact power transmission technology from the reader / writer side, the RFID tag does not contain a battery. Since the RFID tag uses radio waves, communication can be performed simply by holding it over a reader / writer. As the radio frequency, a frequency from a long wave band to an ultra high frequency band (UHF) is used.

  When such an RFID tag is applied to ear tags used for livestock such as cattle, horses, sheep, and animals such as deer, an RFID tag having an animal identification number stored in a microchip is It is embedded in the tag part of the ear tag which consists of a part and a bill part. In addition, there is a method in which an RFID tag is embedded in a reinforced hard part around the hole of a female tag of a two-piece type ear tag, or an RFID tag is embedded in an axis part of an ear tag composed of a shaft part and a tag part. There are advantages and disadvantages to each method.

  Therefore, the present inventor inserts a through hole provided in an RFID tag having appropriate hardness into the shaft portion of the flexible ear tag, and attaches the RFID tag to the ear tag with predetermined play. Thus, an animal ear tag (individual identification tool) that can coexist with the ear tag without damaging the RFID tag has been proposed (see Patent Document 1). The ear tag for animals proposed by the present inventor can reuse the RFID tag attached to the ear tag, and can also be used for animals other than livestock.

Japanese Patent No. 4498013

  However, since the ear tag is generally attached to one or both ears of the animal and the bill part is hanging from the ear, when the RFID tag is attached to the ear tag, the reader / writer installed next to the animal is used. When the ear tag is viewed from the antenna and the RFID tag enters the blind spot of the radio wave, reading may not be successful. In particular, when UHF is used for radio frequency radio waves of the RFID tag, reading was impossible when the RFID tag entered the blind spot.

  Therefore, the present inventor is not an ear tag hanging from the ear, but a metal strip ear tag attached to an upper part of an animal ear shell popular in Europe and the United States, particularly attached to the upper part of a cow ear shell. Since the ear tag is always located above the ear of the animal, it has been found that it is difficult to become a blind spot from above the cow, and the present invention has been achieved. That is, the present invention comprises a strip-shaped ear tag material widely used in Europe and the United States made of a synthetic resin that allows radio waves to pass through, and an RFID tag inside the strip-shaped ear tag that is bent and attached to the ear shell via a gap. It is an object of the present invention to provide a strip-shaped ear tag that can easily read information from the upper direction of the animal.

  The strip-shaped ear tag of the present invention that achieves the above object is a strip-shaped ear tag that is attached to the upper end of the base of the animal's ear shell while penetrating the ear shell while straddling the upper end. A strip-shaped main body constituted by, a shaft portion provided with an arrowhead-shaped shaft tip projecting from one end portion of the strip-shaped main body, and provided at the other end portion of the strip-shaped main body, A synthetic resin plate that is provided on the same side of the main body as the shaft portion of the main body and the microchip and the antenna, and is provided on the same side as the main body shaft portion when the main body is bent at the center. A holding means for slidably holding the RFID tag, and a gap forming means that is provided on the same side as the holding means of the main body and that has a gap between the RFID tag and the main body. It is said.

  As the holding means, in order to enable the RFID tag to slide with respect to the holding means, a bridge-like member spanned from the side surface in the longitudinal direction of the strip-shaped main body to the side surface on the opposite side, the strip-shaped main body A hook-like member that protrudes from the opposing part in the longitudinal direction and the tip part bends inwardly in a bowl shape, or protrudes from the part other than the central part in the longitudinal direction of the strip-shaped main body, and is provided at the upper end part It can be set as the wall-shaped part provided with the collar part which protrudes inside the strip-shaped main body.

  Further, as the gap forming means, a bridge-shaped member, a hook-shaped member, or a pedestal provided between the wall-shaped portion and the upper surface of the strip-shaped main body, the holding means for the strip-shaped main body is formed. A plurality of isolated protrusions or a plurality of protrusions protruding on the surface can be used.

  According to the strip-shaped ear tag of the present invention, the ear specimen is folded at the center and attached to the upper end of the root of the animal ear shell with the ear shell sandwiched therebetween, so the RFID held inside the strip-shaped ear tag Since the antenna of the tag is always positioned above the animal, there is an effect that the RFID tag can be reliably read by the antenna of the reader / writer disposed above the animal. In addition, the RFID tag held inside the strip-shaped ear tag can be moved minutely with respect to the holding means, and is held with an air gap inside the ear sample body. Even if an external force is applied, the external force is not transmitted to the RFID as it is, so the possibility of breakage is low.

It is a perspective view which shows the structure of the modification of the Example of this invention shown in FIG.

  Hereinafter, embodiments of the strip-shaped ear tag of the present invention will be described in detail based on specific examples with reference to the accompanying drawings. Note that the strip-shaped ear tag is different from the general ear tag that is attached so as to hang down from the ear shell, and is reattached so as to sandwich the upper part of the ear root (upper part of the ear shell) that stands upright from the head of the animal. It is for confirmation, and characters and numbers written on the ear tags are not read from a distance. Therefore, the strip-shaped ear tag has a structure that can hold an RFID tag that does not protrude from the main body inside the ear tag when the main body is bent into a U shape at the center. In the embodiment, a specific holding structure of the RFID tag will be described.

  FIG. 1A shows a strip-shaped ear tag 10 according to a first embodiment of the present invention. The strip-shaped ear tag 10 of the first embodiment basically includes a strip-shaped main body 1 made of synthetic resin, and an arrowhead-shaped shaft tip 2E protruding from one end of the main body 1. The shaft portion 2 and a locking portion 3 provided at the other end of the main body 1 are configured. When the main body 1 is bent into a U-shape at the center, the locking portion 3 receives the arrowhead-shaped shaft tip 1E so that it does not come out. The locking hole 3H and the shaft tip storage portion 3C is there. That is, the shaft portion 2 and the locking hole 3 </ b> H of the locking portion 3 are provided on the same surface 1 </ b> A of the main body 1.

  In the strip-shaped ear tag 10 of the first embodiment, a hook-like member 11 is provided on the surface of the main body 1 as a holding means for holding a synthetic resin plate-like RFID tag 6 containing a microchip 4 and an antenna 5. It is provided on 1A. The shape of the RFID tag 6 is an example, and the shape of the antenna 5 is also an example. The hook-shaped members 11 are provided at predetermined intervals at positions facing the edge of the main body 1. Since the central portion of the main body 1 is bent, the hook-shaped member 11 is not provided in the central portion of the main body 1.

  In the first embodiment, the hook-shaped member 11 protrudes from a base portion 13 serving as a gap forming means for allowing a gap to exist between the RFID tag 6 and the main body 1, and has a key 12 at the upper end. Have. As shown in FIG. 1B, the plate-like RFID tag 6 is inserted into the groove portion 14 formed between the key portion 12 and the pedestal portion 13. The width of the groove 14 is slightly larger than the thickness of the RFID tag 6. Since the RFID tag 6 is made of a flexible synthetic resin, both ends of the RFID tag 6 should be inserted into the groove portion 14 from the hook member 11 positioned on the center side of the main body 1 as shown in FIG. In this case, the state shown in FIG.

  In the first embodiment, a bulging portion 2 </ b> S having a diameter larger than that of the shaft portion 2 is provided in a portion of the shaft portion 2 on the main body side. The height of the upper surface of the bulging portion 2S from the surface 1A of the main body 1 is higher than the height of the groove portion 14 provided in the hook-shaped member 11 from the surface 1A of the main body 1. A ring portion 3 </ b> S is formed around the locking hole 3 </ b> H of the locking portion 3. The height of the upper surface of the ring portion 3S from the surface 1A of the main body 1 is higher than the height of the groove portion 14 provided in the hook-shaped member 11 from the surface 1A of the main body 1. The RFID tag 6 held by the hook member 11 is slidable with respect to the hook member 11. Therefore, the bulging portion 2S and the ring portion 3S function as a stopper member that prevents the RFID tag 6 held by the hook-shaped member 11 from coming out of the main body 1 even if it slides in the longitudinal direction of the main body 1.

  In addition, the shape of the bulging part 2S and the ring part 3S may not be cylindrical. Moreover, since the RFID tag 6 held by the hook-like member 11 is difficult to be removed from the shaft portion side by the shaft portion 2, the bulging portion 2S can be omitted. Furthermore, instead of the ring portion 3S, another stopper projection can be provided on the surface 1A of the main body 1 between the locking hole 3H and the hook-like member 11.

  The strip-shaped ear tag 10 shown in FIG. 2A in which the RFID tag 6 is held by the hook-shaped member 11 is U-shaped at the center portion with the shaft portion 2 inward so that the shaft tip 2E can be inserted into the locking hole 3H. It can be bent into a letter shape. At this time, the inside of the strip-shaped ear tag 10 is shrunk, and the RFID tag 6 is pushed out to both end portions of the main body 1. However, since the RFID tag 6 is slidably held by the hook member 11, Can move. In addition, the pedestal 13 has a gap between the main body 1 and the surface 1A. The shaft tip 2E is inserted into the shaft tip storage portion 3C through the locking hole 3H of the locking portion 3 after passing through the cow's ear shell 51 indicated by a two-dot chain line in FIG. 2 (b). . The shaft tip 2E inserted into the shaft tip storage portion 3C does not come out of the shaft tip storage portion 3C.

  The RFID tag 6 held inside the strip-shaped ear tag 10 can be moved minutely with respect to the hook member 11 and is held with an air gap inside the ear specimen 1. Even if an unexpected external force is applied to 1, the external force is not directly transmitted to the RFID tag 6 due to the gap portion and the slide, so that the possibility of breakage is low.

  FIG. 3A shows a state in which the strip-shaped ear tag 10 shown in FIG. 2A is bent in a U shape at the central portion and attached to the ear shell 51 of the cow 50. Ordinary ear tags 55 are already attached to the ear shells 51 on both sides of the cow 50. The normal ear tag 55 is generally attached to the center of the ear shell 51 or slightly below the center. On the other hand, the strip-shaped ear tag 10 of the present invention is attached to the upper portion 53 of the root portion 52 of the ear shell 51. A cross mark is the attachment portion 54 of the strip-shaped ear tag 10.

  The upper portion 53 of the root portion 52 of the ear shell 51 of the cow 50 is curved toward the front side of the cow 50 as shown in FIG. The strip-shaped ear tag 10 of the present invention is attached to the ear shell 51 with the ear shell 51 sandwiched from the upper end of the ear shell 51. At this time, the strip-shaped ear tag 10 is bent with the shaft portion 2 on the upper side and the locking portion 3 on the lower side, and the shaft tip 2E is inserted into the ear shell 51 from the upper side of the ear shell 51 to the locking portion 3. Locked. FIG. 3C shows a state where the strip-shaped ear tag 10 is attached to the ear shell 51 of the cow 50.

  FIG. 4 shows a state of communication between the reader 60 and the strip-shaped ear tag 10 holding the RFID tag 6 attached to the upper portion 53 of the root portion 52 of the ear shell 51 of the cow 50.

The control circuit 66 can communicate with the outside, and is connected to an external communication circuit network such as the Internet through a telephone line or the like. The radio wave used is, for example, a UHF radio wave.

  The reader 60 emits an electromagnetic wave for supplying power from the transmitting antenna 61. The electromagnetic wave is also used as a carrier wave for data transmission. Data is superimposed on this carrier wave via a modulator 64. The electromagnetic wave radiated from the transmitting antenna 61 is received by the antenna (not shown) of the RFID tag 10, and the data encoded in the microchip (not shown) is demodulated from the modulated carrier wave. The mechanism for data transmission from the RFID tag 10 to the reader 60 is the same. Therefore, the individual identification data stored in the memory in the microchip of the RFID tag 10 is read by a request from the reader 60 side, encoded by the modulator, and superimposed on the electromagnetic wave radiated from the antenna.

  On the reader 60 side, the electromagnetic wave radiated from the antenna of the RFID tag 10 is received by the receiving antenna 62, and the individual identification data included in the electromagnetic wave is demodulated by the demodulator 65 and sent to the control circuit 66. The control circuit 66 sends the demodulated data to a predetermined processor such as an internet data center or a livestock registration agency via the data processing device connected to the reader 60 or the Internet. The reader 60, the transmitting antenna 61, and the receiving antenna 62 can be installed separately. Since the strip-shaped ear tag 10 is attached to the upper portion 53 of the ear shell 51 and the antenna is also substantially horizontal, the transmitting antenna 61 and the receiving antenna 62 are located above the cow 50. If it is installed, it is possible to reliably read the strip-shaped ear tag 10 from above, regardless of which direction the cow 50 faces.

The provided ring portion 3S is removed. This is because the RFID tag 6A is locked to the shaft portion 2 by the through hole 6H, so that the RFID tag 6A is not detached from the main body 1, and the bulging portion 2S and the ring portion 3S corresponding to the stopper member are unnecessary. Because it becomes. Further, even when the strip-shaped ear tag 10B to which the RFID tag 6A is attached is folded in a U shape at the center, the RFID tag 6A can slide inside the hook-shaped member 11, so there is no risk of breakage.

  FIG. 8 shows a configuration of a strip-shaped ear tag 30B of a modified example of the strip-shaped ear tag 10B shown in FIG. The strip-shaped ear tag 30B of this modified example also holds the RFID tag 6A in which the through-hole 6H is provided in the extended portion 6E, and the same constituent members as those of the strip-shaped ear tag 10B described in FIG. Reference numerals are assigned and explanations thereof are omitted. The strip-shaped ear tag 30B is provided with only one bridge-like member 31A on the side of the locking hole 3H. The height of the bridge member 31A from the surface 1A of the main body 1 of the bridge 32A is the same as the height from the surface 1A of the main body 1 of the bridge 32 shown in FIG. Is provided with a ridge 35 shown in FIG. The length of the bridge-shaped member 31A in the longitudinal direction of the main body 1 is formed longer than the length of the bridge-shaped member 31 shown in FIG. 6C, and the end surfaces of both openings are cut obliquely. .

  Furthermore, both end portions of the main body 1 have a circular shape with no corners, so that the ear shell is not damaged. Needless to say, the configuration in which the corners at both ends of the main body 1 are not curved and the corners are circular can be implemented for the main body 1 of all the embodiments. Moreover, you may provide the guard 36 which prevents the RFID tag 6A from protruding from the main body 1 as shown by a broken line at both ends of the portion where the bridge-like member 31A of the main body 1 is not provided. When the RFID tag 6A is held by the strip-shaped ear tag 30B configured as described above, after inserting the through hole 6H of the RFID tag 6A through the shaft portion 2, the opposite end of the bridge-shaped member 31A is inserted. What is necessary is just to insert in the slit 34A.

  Further, in the strip-shaped ear tag 30B configured to hold the RFID tag 6A by inserting the through hole 6H through the shaft portion 2 of the RFID tag 6A having the through hole 6H, only the guard 36 is provided without providing the bridge-shaped member 31A. May be configured to protrude from the main body 1 on the side of the locking hole 3H. In this case, the guard 36 may be continuous in a wall shape. That is, the cross-section in the short direction of the main body 1 of the strip-shaped ear tag 30B may be simply formed in a U shape.

  As mentioned above, although the embodiment which attaches the strip-shaped ear tag which can hold | maintain the RFID tag of this invention inside a cow's ear shell was demonstrated, the strip-shaped ear tag which can hold | maintain the RFID tag of this invention inside is attached to a cow. The ear shell can be attached to the ear shell of an animal standing upright from the head.
