Description

    The present invention relates to an RFID (Radio Frequency Identification) tag, an RFID tag continuum, and an RFID tag producing method, and more particularly, an RFID tag for mounting on a metal product, an RFID tag continuum, and an RFID tag producing method. It is about.

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

If the article is made of metal and the RFID tag is attached in a state of being too close to the article, data communication between the RFID antenna and a reader / writer having a writer antenna capable of wireless communication is possible. There is a problem that troubles are likely to occur.
In order to solve this problem, particularly in the case of an RFID inlet that uses radio waves in the HF band (3 MHz to 30 MHz (for example, 13.56 MHz)), the magnetic permeability between the RFID inlet and the metal product is relatively high. By interposing a magnetic sheet (RFID magnetic sheet), the magnetic flux from the lighter antenna passes through the magnetic sheet and an induced current flows to the RFID antenna, enabling wireless communication between the RFID antenna and the lighter antenna. ing.

However, since the RFID magnetic sheet is used by interposing it between an RFID tag configured to have predetermined display information (fixed information) in advance and a metal product, it is necessary for the RFID tag. Depending on the situation, it is difficult to display arbitrary variable information, and there is a problem that its usage is limited.
Furthermore, since the RFID magnetic sheet requires a space for the magnetic flux to pass through during the data communication, a certain thickness is required, and the total thickness of the RFID tag is increased. Therefore, there is a problem that it is difficult to print by sandwiching and transferring the RFID tag between a print head and a platen roller in the printer.
In order to print and display variable information on the RFID tag, there is one in which the holding portion of the RFID inlet is bent away from the other portion so as to stand up from the metal surface (Patent Document 1). However, it is not all-purpose because it takes time to bend. Therefore, a method has been adopted in which the RFID magnetic sheet is attached after the RFID tag is printed and issued. However, there is a problem that it is difficult and troublesome to attach the RFID magnetic sheet in accordance with the position of the RFID inlet.

In a state where the material 4 is folded, the RFID inlet 5 and the RFID magnetic sheet 6 can face each other.
The first region 11 and the second region 12 have the adhesive layer 7 on their back surfaces (more precisely, so as to surround the periphery of the RFID inlet 5 and the RFID magnetic sheet 6). While being able to bond together, each tag base material 4 can be temporarily attached on the strip | belt-shaped mount 2. As shown in FIG.

    The RFID inlet 5 has an IC chip 14 and an RFID antenna 15 on a film-like inlet sheet 13 and can perform data communication by radio.

The RFID magnetic sheet 6 is obtained by kneading metal powder having a relatively high magnetic permeability and low magnetic loss into a synthetic resin sheet, and at least the RFID antenna of the RFID inlet 5 in a state where the tag base 4 is folded. 15 can be covered.
As the metal powder, for example, a metal such as iron or nickel, a metal oxide such as ferrite, or an alloy such as permalloy is preferably used. The shape of the powder may be isotropic, anisotropic, or flat.

    A position detection mark 16 for detecting the relative position of the RFID tag 3 in a printer (thermal printer 17, FIG. 3) is printed in advance on the back surface of the mount 2.

As described above, the fixed information 8 and the variable information 9 can be printed on the surface of the tag base 4, and FIG. 3 is a schematic side view of the thermal printer 17 for printing on the tag base 4. 4 is an explanatory view of the RFID tag 3 printed by the thermal printer 17, wherein FIG. 4 (1) is a plan view of the RFID tag 3, and FIG. 4 (2) is a back view of the RFID tag 3. .
The thermal printer 17 includes a supply unit 18 of the RFID tag continuum 1, a detection unit 19, a data reading / writing unit 20, a printing unit 21, and a cutting unit 22.

    The supply unit 18 holds the RFID tag continuous body 1 in a roll shape, and can feed the RFID tag continuous body 1 in a strip shape in the direction of the detection unit 19, the data reading / writing unit 20, and the printing unit 21.

    The detection unit 19 includes an optical sensor 23 that can detect the position detection mark 16 located on the back surface of the RFID tag continuous body 1.

The data read / write unit 20 has a built-in antenna 24, can read / write data to / from the IC chip 15 by data communication with the RFID inlet 5, and is provided near the print unit 21, Data communication can be performed almost simultaneously with the printing of various information (variable information 9) on the surface of the RFID tag 3 by the printing unit 21.
The position where the built-in antenna 24 (data read / write unit 20) is provided may be on the upstream side or the downstream side of the printing unit 21, or may be on the back side (mounting paper 2 side) of the RFID tag continuous body 1.

The printing unit 21 includes a thermal head 25 and a platen roller 26, and a supply shaft 28 and a winding shaft 29 for the thermal transfer ink ribbon 27.

The variable information 9 can be printed on the surface.
The fixed information 8 is displayed in advance on the surface of the RFID tag 3 by, for example, a printing machine (not shown), for example, “Management No.”, and the thermal printer 17 sets the management No. as variable information 9. For example, a visually recognizable “XXΔΔ” and an optically readable barcode are printed.

The cutting unit 22 includes a fixed blade 30 and a movable blade 31, and cuts the RFID tag continuous body 1 at a predetermined pitch to obtain a single-leaf RFID tag 3 with a mount 2.
Instead of the single RFID tag 3, a plurality of RFID tags 3 can be collectively cut by the cutting unit 22, and can be handled in a band shape or in a roll shape.

In the RFID tag continuum 1 and the RFID tag 3 having such a configuration, the RFID tag 3 can be obtained in a state where the RFID magnetic sheet 6 is built and laminated in contact with the RFID inlet 5 in advance.

When printing on the RFID tag continuum 1 (RFID tag 3) in the thermal printer 17, the thickness is almost half that of the final folded state, so that the mechanical load when printing with the thermal printer 17 is performed. And damage to the IC chip 14 is avoided. Furthermore, since the thick RFID magnetic sheet 6 can be used, more stable data communication is possible even on the metal surface (metal product M, FIG. 6). In addition, the fixed information 8 and the variable information 9 can be displayed on the front and back surfaces of the RFID tag 3 in the same manner as the display by double-sided printing.

You may make it offer.
Therefore, even if the metal product M is close to the RFID inlet 5, radio waves from the reader / writer 33 concentrate on the RFID magnetic sheet 6 beyond the RFID inlet 5, and as a result, the reader / writer 33 performs data transfer with the RFID tag 3. Communication can be performed effectively.
Furthermore, since the RFID tag 3 itself has the RFID magnetic sheet 6 therein, the attachment form of the RFID tag 3 can be selected as necessary.

FIG. 7 is a plan view of the RFID tag continuum 40 according to the second embodiment of the present invention. Different.
That is, the fold line 10 in the RFID tag 41 of the RFID tag continuum 40 is a direction along the flow direction (transfer direction) of the RFID tag continuum 40.
Other configurations are substantially the same as the configurations of the RFID tag continuum 1 and the RFID tag 3.

    In the RFID tag continuum 40 and the RFID tag 41 having such a configuration, similarly to the RFID tag continuum 1 and the RFID tag 3 (FIGS. 1 and 2), the thermal tag 17 (FIG. 3) is used to attach the RFID tag 41 to the RFID tag 41. The desired variable information 9 can be printed as necessary, and even if the RFID tag 41 is attached to the metal product M, the data communication function can be accurately retained.
