Description

    The present invention relates to an RFID (Radio Frequency Identification) tag, and more particularly to an RFID tag to be attached to a metal product.

    Conventionally, an RFID tag equipped with an RFID inlet that has an IC chip and an RFID antenna and can wirelessly write and read data is attached to various items, and various data about these items are read and written. It is used in various fields such as data management.

Therefore, when the article is made of metal, if the RFID tag is attached in a state where it is too close to the article, there is a problem that data communication is likely to be hindered.
In order to solve this problem, there is an RFID tag in which a holding portion of the RFID inlet is bent at a bent portion so that the RFID inlet is separated from other portions to stand like a flag from a metal surface.

However, such an RFID tag is made of paper and is not stable because the bent portion is not fixed, its standing state is unstable, and there is a difference in data communication performance depending on the mounting condition of the RFID tag. It has a problem in long-term use and environmental resistance.
Furthermore, since a double-sided tape or the like is used to attach the RFID tag to a metal product, there is a problem that the product cannot be used in the case of a product having a surface that is difficult to fix with the double-sided tape.

    Moreover, this invention makes it a subject to provide the RFID tag which can give stability to the bending part of an RFID tag.

    Another object of the present invention is to provide an RFID tag that can be produced at low cost.

    That is, the present invention uses a string-like binding band for mounting and fixing an RFID tag, and bends the RFID tag by bringing the RFID tag into contact with the head portion of the binding band, so that the surface of a metal product or other mounting product is used. In the present invention, a tag base material and an RFID inlet equipped with the tag base material and having an IC chip and an RFID antenna and capable of wireless data communication are provided. The RFID tag has a single-layer base material, and the RFID base material is attached to the tag base material. The tag base material has a strap-shaped band main body, The head has a head formed at one end of the band body and a tail formed at the other end of the band body. A through hole is formed through which a binding band capable of attaching the RFID tag to an article is inserted by being inserted into and engaged with a through engagement hole of the head portion, and the through hole is formed by the head portion of the binding band. The tag base is formed smaller, and the tag base includes a standing base region for raising the RFID inlet with respect to the article with the through hole as a boundary, and the standing base with the RFID inlet. The RFID tag is characterized by defining an inlet holding region that can stand up from the region.

    The through hole includes a first through hole in the thickness direction of the tag base material and a second in the thickness direction of the tag base material formed at a different position in parallel with the first through hole in the vertical direction. Through-holes.

It is a top view of the RFID tag 40 by the 3rd Example of this invention.

    In the present invention, since the RFID band is attached to the metal product or other article by inserting the binding band through the through hole of the tag base material, the RFID inlet is stably and reliably attached over a long period of time while being separated from the surface of the article. The RFID tag that can guarantee the data communication function is realized.

Next, an RFID tag 1 according to a first embodiment of the present invention will be described with reference to FIGS.
1 is a plan view of the RFID tag 1, FIG. 2 is a cross-sectional view taken along the line II-II of FIG. 1, FIG. 3 is a cross-sectional view taken along the line III-III of FIG. 2 and the RFID inlet 3.

    The tag base material 2 is a sheet base material made of, for example, a synthetic resin having predetermined flexibility or elasticity and rigidity, and has an RFID inlet 3 therein.

The RFID inlet 3 includes an inlet base 4 made of, for example, polyethylene terephthalate or a laminated film thereof, an IC chip 5 and an RFID antenna 6 and can perform wireless data communication.
The RFID inlet 3 is, for example, UHF band (300 MHz to 3 GHz (preferably 860 to 960 MHz, more specifically 433 MHz, 900 MHz, 915 to 928 MHz, 950 to 958 MHz) or microwave (1 to 30 GHz, specifically 2 .45 GHz), HF band (3 MHz to 30 MHz (preferably 13.56 MHz)), 135 kHz or lower, and other necessary radio waves in a predetermined frequency band and electromagnetic action, etc. are required for the IC chip 5 via the RFID antenna 6. Read and write data (data communication) wirelessly.
However, the specific configurations of the IC chip 5 and the RFID antenna 6 are appropriate according to the radio waves used.
In particular, in the case of using a radio wave having a wavelength in the UHF band (for example, 860 to 960 MHz), the communication distance is usually about 5 to 10 m, and applications in various fields are expected.

In the tag base 2, a through hole 8 for inserting the binding band 7 (FIGS. 5 and 6, described later) is formed at a position avoiding the area of the RFID inlet 3.
The through hole 8 is formed by penetrating in the thickness direction of the tag base 2 and has a first through hole 8A having an elongated rectangular shape (see FIG. 1) and a vertical direction in the first through hole 8A. And a second through hole 8 </ b> B having a rectangular shape in the thickness direction of the tag base 2 formed in parallel at a different position. The first through hole 8A and the second through hole 8B can be formed in a slit shape as long as the tail portion 17 and the band main body 15 of the binding band 7 can be inserted.
The tag base 2 includes a standing base region 2A for raising and separating the RFID inlet 3 with respect to the article with the through hole 8 (first through hole 8A) as a boundary, and the RFID inlet 3 and this standing. This is defined in an inlet holding region 2B that can stand up from the base portion region 2A.

Furthermore, since the tag base material 2 has predetermined flexibility or elasticity and rigidity, it is in the portion of the through hole 8 (first through hole 8A), specifically, in the opening length direction of the first through hole 8A. It is possible to bend at the bent portion 9 along.
In order to ensure this flexibility, a cut line or a broken line 10 (imaginary line in FIG. 1) is formed in advance along the bent portion 9 in the lateral direction portion of the first through hole 8A as necessary. It may be left.
As shown in FIG. 1, the standing base region 2 </ b> A is a region located below the bent portion 9 in the drawing, and the inlet holding region 2 </ b> B is a region located above the bent portion 9.

The cross-sectional structure of the RFID tag 1 (tag base material 2) shown in FIG. 2 and FIG. 3 is a single-layer structure, and the adhesive 11 or the like is attached to any one surface (the back surface in the illustrated example) of the tag base material 2. The RFID inlet 3 is attached.
FIG. 4 is an exploded cross-sectional view of the RFID tag 1 similar to that of FIG. 3, and the tag base 2 is a single-layer base, for example, a soft vinyl chloride material or other arbitrary material is adopted as a soft material. Thus, the RFID tag 1 can be manufactured at a relatively low cost while ensuring flexibility or elasticity as the RFID tag 1. Of course, the required rigidity can be ensured by employing a hard material such as PET.

As shown by a virtual line in FIG. 4, a label 12 is attached so as to cover the RFID inlet 3 to protect the RFID inlet 3 and label data such as a barcode related to management information held by the RFID inlet 3. 12 can be displayed.
Further, instead of the label 12, the protective film 13 can be laminated and coated on the RFID inlet 3, or the label 12 can be attached to the surface side of the tag base 2.
Furthermore, a so-called RFID label constructed by laminating a label 12 on the RFID inlet 3 can be temporarily attached to a belt-like mount and loaded into a printer (both not shown), and variable information can be printed on the label 12 as required. In addition, the printed RFID label can be attached to the tag base 2. Further, data may be written to the IC chip 5 when printing with a printer.

    FIG. 5 is a side view of the binding band 7, and FIG. 6 is an enlarged cross-sectional view of the main part of the binding band 7. The binding band 7 is generally available and is made of, for example, nylon. A strap-shaped band main body 15 having a predetermined length, a bulged head portion 16 formed at one end of the band main body 15, and a taper formed at the other end of the band main body 15. And a tail portion 17 having a shape.

    In particular, as shown in FIG. 6, a through engagement hole 18 is formed in the head portion 16, and a fixing elastic engagement protrusion 19 is formed in the through engagement hole 18.

On one surface of the band main body 15, an uneven belt-like engagement that engages with the fixing elastic engagement protrusion 19 and can be fixed by tightening the entire binding band 7 into a ring shape having an arbitrary circumferential length. A joint portion 20 is formed.
Further, an uneven portion 21 is formed on one surface of the tail portion 17 so that the tail portion 17 can be easily pinched.
Therefore, the tail portion 17 is first inserted through the first through hole 8A and the second through hole 8B of the RFID tag 1 and through the through engagement hole 18 of the head portion 16 to the fixing elastic engagement protrusion 19. The RFID tag 1 is attached to an article (metal product M, FIG. 7, which will be described later) by engaging any part of the band-shaped engagement portion 20 to form the band body 15 in a ring shape having a predetermined circumferential length. Is possible.

    However, the through hole 8 (the first through hole 8A, the second through hole 8B, FIGS. 1 and 3) needs to be formed smaller than the head portion 16 of the binding band 7.

In the RFID tag 1 having such a configuration, the RFID tag 1 can be attached to an arbitrary article (for example, the metal product M) using the binding band 7.
That is, FIG. 7 is a side view showing a state in which the RFID tag 1 is attached to an arbitrary metal product M using the binding band 7, and FIG. 8 is an illustration of attaching the RFID tag 1 to the metal product M using the binding band 7. It is a side view which shows the state.
As shown in FIG. 7, the band main body 15 is inserted in a state where the binding band 7 is inserted from the tail portion 17 into the through hole 8 (first first through hole 8A and then the second through hole 8B) of the tag base 2. Is wound around the metal product M, and the tail portion 17 is inserted into the through-engagement hole 18 of the head portion 16.

    Next, as shown in FIG. 8, the tail portion 17 is further pulled out with respect to the head portion 16, and the metal product M is tightened by the ring-shaped band body 15, and the tag base is attached to the head portion 16 of the binding band 7. By raising the material 2, the standing base region 2A located between the first through hole 8A and the second through hole 8B is in close contact with the outer surface of the metal product M, and the inlet holding region 2B is bent. Since the portion 9 is bent and rises from the metal product M, the RFID tag 1 can be attached to the metal product M so that the RFID inlet 3 in the inlet holding region 2B is separated from the metal product M. it can. Therefore, since the RFID inlet 3 is kept away from the metal product M, the data communication function can be maintained.

    However, since the engagement state of the fixing elastic engagement protrusion 19 and the concavo-convex belt-like engagement portion 20 in the head portion 16 is maintained, the tag base material 2 rides on the head portion 16 of the binding band 7. The state is fixed, and the state where the RFID inlet 3 is separated from the metal product M can be stably and reliably realized.

Further, since the band main body 16 or the tail portion 17 has a predetermined rigidity, the tag base 2 in a direction in which the tail portion 17 of the binding band 7 further separates the inlet holding region 2B (RFID inlet 3) from the metal product M. Since the (inlet holding area 2B) can be biased, the standing posture of the inlet holding area 2B by the head portion 16 can be supplementarily maintained.
In addition, when the tail part 17 is too long, the front-end | tip part can also be cut off as needed.

    In the present invention, the metal product is inserted in the same way as described above by inserting only the first through hole 8A without inserting the binding band 7 (tail portion 17) into the second through hole 8B of the through hole 8. The RFID tag 1 can be attached to M.

Furthermore, only the first through hole 8 </ b> A can be formed as the through hole 8.
That is, FIG. 9 is a plan view of an RFID tag 30 according to a second embodiment of the present invention. In the RFID tag 30, a single through hole 8 (for example, the first through hole 8A) is formed in the tag base 2. ) Only.
Since the other structure is practically the same as the RFID tag 1 according to the first embodiment, the same parts are denoted by the same reference numerals, and detailed description thereof is omitted.

Also in the RFID tag 30 having such a configuration, the RFID tag 30 can be attached to an arbitrary metal product M using the binding band 7 as in the RFID tag 1 (first embodiment, FIG. 1).
That is, FIG. 10 is a side view showing a state where the RFID tag 30 is attached to the metal product M using the binding band 7.
In a state where the binding band 7 is inserted from the tail portion 17 into the through hole 8 (first through hole 8A) of the tag base member 2, the band main body 15 is hung around the metal product M, and the tail portion 17 is attached to the head portion 16. As shown in FIG. 10, the tail part 17 is further pulled out with respect to the head part 16, and the metal product M is tightened by the ring-shaped band body 15, as shown in FIG. By causing the tag base material 2 to ride on the head portion 16 of the binding band 7, the base region 2 </ b> A for standing is in close contact with the outer surface of the metal product M, and the inlet holding region 2 </ b> B is bent at the bent portion 9 to form metal. Since the product M stands up, the RFID tag 30 can be attached to the metal product M so that the RFID inlet 3 is separated from the metal product M.

    However, as already described with reference to FIGS. 7 and 8, since the engagement state of the fixing elastic engagement protrusion 19 and the uneven belt-shaped engagement portion 20 in the head portion 16 is maintained, The state in which the tag base material 2 rides on the head portion 16 of the binding band 7 is fixed, and the state in which the RFID inlet 3 is separated from the metal product M can be stably and reliably realized. In this case, it is desirable that the thickness direction through hole 8A has a size close to the cross section of the band main body 15 of the binding band 7 and is not easily loosened.

    Similarly, since the band body 16 or the tail portion 17 has a predetermined rigidity, the tail portion 17 of the binding band 7 causes the tag holding base 2B (RFID inlet 3) to move further away from the metal product M. Since the material 2 can be urged, the standing posture of the inlet holding region 2B by the head portion 16 can be supplementarily maintained.

In the present invention, the shape, orientation, position, and number of the through holes 8 as well as the shape of the tag base 2 are the same as the size and width of the RFID antenna 6 of the RFID inlet 3, the shape and size of the metal product M, It can be arbitrarily designed according to the type of the binding band 7 and the like.
For example, FIG. 11 is a plan view of an RFID tag 40 according to a third embodiment of the present invention. In the RFID tag 40, the through holes 8 (the first through hole 8A and the second through hole 8B) are tags. In the base material 2, at least a plurality of them (two in the illustrated example) are formed in parallel with each other along the bent portion 9.
Other configurations are substantially the same as the RFID tag 1 described above (first embodiment, FIG. 1).

    Even in the RFID tag 40 having such a configuration, the binding band 7 can be inserted and engaged with each through-hole 8, and the RFID tag 40 (particularly, the RFID antenna 6) has a size that spreads in the lateral direction. It is possible to stably and securely attach to the required metal product M, and to stand the inlet holding region 2B (RFID inlet 3) away from the metal product M, thereby extending the communication distance. .
