Abstract

(57) [Abstract] [Purpose] To provide an ID tag having a structure that can be easily attached to and removed from an article. [Structure] An electronic circuit on which a non-contact signal transmitter group and an electronic component group are mounted is mounted on an annular member formed of a flexible polymer material such as silicone rubber. With such a structure, an adhesive or the like is unnecessary for attaching the tag to the article, and as a result, the intended purpose can be achieved.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an ID tag used for writing and reading item identification information and management information in a production line or the like.

[0002]

[Prior Art]

 The ID tag has a wireless communication and memory function, and is a transponder whose internal memory is accessed by a wireless command code from a reader / writer, and is called a data carrier in the Automatic Identification Manufacturers Association (AIM J).

Further, as a structure of this type of ID tag, an epoxy resin has been conventionally used for the purpose of protecting an electronic circuit on which a non-contact signal transmitter group and an electronic component group are mounted against water and heat. A material with high water resistance and heat resistance, such as resin or glass, is generally molded into a card shape or a cylindrical shape.

The ID tag having such a structure is usually used by being attached to a target article with an adhesive.

[0005]

[Problems to be solved by the device]

 By the way, the characteristics of the ID tag are that it is possible to read a large amount of information as compared with a commonly used bar code, and that it is easy to write and rewrite information. On the other hand, it is disadvantageous in that it is expensive because it is composed of electronic components such as ICs.

For this reason, as long as the attachment method such as sticking to the article with the current adhesive is adopted, it is difficult to reuse the tag, and therefore the article or the article itself that manages information for a long period of time cannot be used. Inevitably, only expensive ones were used, and this was a factor that prevented the spread of ID tags.

The present invention has been made in view of such circumstances, and an object thereof is to provide an ID tag having a structure that can be easily attached to and detached from an article or the like.

[0008]

[Means for Solving the Problems]

 A configuration for achieving the above object will be described with reference to FIG. 1 corresponding to an embodiment. The present invention is directed to functional parts 13 and 14 for transmitting a non-contact signal and information writing / reading. It is characterized in that it has an electronic circuit 1 on which the functional components 11, 12 and so on are mounted, and that the electronic circuit 1 is mounted on an annular member 2 formed of a flexible polymer material. .

[0009]

[Action]

 The annular member 2 can be attached to the outer periphery of the article (steel pipe) 20 by, for example, as shown in FIG. Further, by pulling out the annular member 2 from this mounted state, the fastening to the article 20 can be released, so that the article 20 can be easily detached.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram of an embodiment of the present invention, in which (a) and (b) show a central longitudinal sectional view and an external perspective view, respectively.

First, a schematic configuration of the electronic circuit 1 of the ID tag according to the embodiment of the present invention will be described with reference to FIG. The electronic circuit 1 of this ID tag includes a reception antenna 13 and a transmission antenna 14 as a non-contact signal transmitter. Also, as electronic parts, the main control unit 11, the data memory 12, the demodulator 15 for demodulating the received signal and guiding it to the main control unit 11, and the signal from the main control unit 11 are modulated based on the frequency of the oscillator 17. It is equipped with a modulation / amplifier 16 that leads to a transmitting antenna 14, an SP / PS converter 11a provided at the output stage of the main control unit 11, and a battery 18 for supplying power to each functional component. .. The electronic circuit 1 having the above-described configuration has a configuration equivalent to that of an electronic circuit used for a general ID tag, and the entire electronic circuit 1 is generally used in an electronic circuit such as an epoxy resin, a polyimide resin, or a ceramic material. It is molded with the molding material 1a. The external dimensions after molding are, for example, height 10 mm, width 30 mm, and thickness 5 mm.

In the embodiment of the present invention, the electronic circuit 1 having the structure shown in FIG. 2 is embedded inside the annular member 2. The annular member 2 has a donut shape in which a circular cross section is uniformly continuous along a perfect circle, and a flexible polymer material such as silicone rubber is used as the material. The outer dimensions of the annular member 2 are, for example, 80 mm in the inner diameter and 100 mm in the outer diameter, and the diameter of the circular cross section is about 20 mm.

The ID tag 10 having the above structure is used, for example, for product management of a steel pipe (outer diameter 90 mm × length 1000 mm). As shown in FIG. 3, the attachment to the article is performed by inserting the steel pipe 30 into the inside of the ring while the ring-shaped member 2 is stretched and expanded outward. Follow the same procedure as for a general rubber band such as "Release". In addition, at the time of removal, the annular member 2 is pulled out and pulled out from the steel pipe 30 in a state where the fastening to the steel pipe 30 is released. As described above, the ID tag 10 according to the embodiment of the present invention can be easily attached / detached to / from an article, and it is not necessary to use an adhesive or the like for the attachment.

Here, as the material of the annular member 2, in addition to silicone rubber, for example, natural rubber or another flexible polymer material such as polyamide, polyethylene, or fluororesin may be used. It is preferable to use a polymer material having rubber properties in consideration of improving the wearability of the article.

Further, the shape of the annular member 2 does not need to be a perfect circular ring, and may be an elliptical ring or a rectangular ring. Further, the sectional shape is circular or rectangular. Other shapes such as the above may be adopted. Furthermore, the outer diameter of the annular member 2 is not limited to the above-mentioned dimensions, but considering the convenience of use, for example, the inner diameter is preferably about 20 to 1000 mm.

In the above embodiment, the electronic circuit 1 is embedded in the ring-shaped member 2. However, the structure is not limited to this. For example, as shown in FIG. Other structures such as disposing the protective package 23 having an electronic circuit therein and mounting the package 23 on the annular member 21 via the supporting member 21a may be adopted.

[0017]

[Effect of the device]

 As described above, according to the present invention, the electronic circuit on which the non-contact signal transmitter group and the electronic component group are mounted is attached to the flexible polymer material annular member. No adhesive or the like is needed when mounting the product on the product, which facilitates the installation work and eliminates the deterioration of the quality of the product such as dirt on the surface due to the adhesive or the like. Moreover, the tag once attached can be easily removed from the article, which allows the tag to be recycled (recovered and reused), resulting in a reduction in tag cost.
