Description

The present invention relates to a non-contact type data receiver / receiver that can receive information from the outside using electromagnetic waves as a medium, and can transmit information to the outside, such as an information recording medium for RFID (Radio Frequency IDentification).
In particular, the non-contact type data receiving / transmitting body according to the present invention is suitably used when affixing to a metal article.

In recent years, non-contact type data transmission / reception has been made possible, such as non-contact IC tags and RFID (Radio Frequency IDentification) information recording media, which can receive information from the outside using electromagnetic waves as a medium and can transmit information to the outside. The body has been proposed.
An IC label, which is an example of a non-contact type data receiving / transmitting body, generates an electromotive force in an antenna by a resonance action when receiving an electromagnetic wave from a reader / writer, and the IC chip in the IC label is activated by this electromotive force. This information is converted into a signal, and this signal is transmitted from the antenna of the IC label.
A signal transmitted from the IC label is received by the antenna of the reader / writer, sent to the data processing device via the controller, and data processing such as identification is performed.

  In order for these IC labels to operate, the electromagnetic waves transmitted from the reader / writer must be sufficiently taken into the antenna of the IC label, and an electromotive force greater than the operating electromotive force of the IC chip must be induced. Is attached to the surface of the metal article, the magnetic flux is parallel to the surface of the metal article on the surface of the metal article. For this reason, since the magnetic flux crossing the antenna of the IC label is reduced and the induced electromotive force is lowered, there is a problem that the IC chip is not operated due to being lower than the operating electromotive force of the IC chip (for example, see Non-Patent Document 1) .).

  FIG. 5 is a schematic diagram showing the flow of magnetic flux when an IC label is placed on the surface of a metal article. Since the magnetic flux 42 generated from the reader / writer 41 is parallel on the surface of the metal article 43, the magnetic flux passing through the antenna 45 of the IC label 44 placed on the surface of the metal article 43 is reduced and induced by the antenna 45. Since the electromotive force that is generated decreases, the IC chip 46 does not operate.

  Therefore, in order to operate even when placed on a metal article, an antenna is wound around a ferrite core, and the axis of this antenna is arranged so as to be parallel to the direction of magnetic flux on the surface of the metal article. And the method of increasing the induced electromotive force by increasing the magnetic flux which passes an antenna surface is proposed (for example, refer patent document 1).

  FIG. 6 is a perspective view of an IC tag according to the embodiment of Patent Document 1. An antenna 62 is wound around a square ferrite core 56, and a base substrate 55 is interposed via a base substrate 55 in a portion where the antenna 52 is not wound. An IC chip 53 and a capacitor 54 are mounted on 55. When the flat portion of the rectangular ferrite core 56 (the lower surface in FIG. 6) is attached to the surface of the metal article, a magnetic flux parallel to the surface of the metal article passes through the ferrite core 56 and passes through the antenna 52 at a right angle. Therefore, a required induced voltage is generated and the IC chip 53 is activated.

  On the other hand, an antenna is formed in a flat shape, and magnetic flux is passed through a magnetic core member provided on the lower surface of the antenna, thereby causing magnetic flux to pass through the antenna formed in a flat shape and generating an induced electromotive force in the antenna. In addition, there is a proposal to provide a conductive member on the lower surface of the magnetic core member to prevent the effect of the article to be placed on the IC label (for example, see Patent Document 2).

FIG. 7 is a cross-sectional view showing an embodiment of Patent Document 2. In FIG. The IC label antenna 61 includes a conductor 61a wound in a spiral shape in a plane, a plate-like or sheet-like magnetic core member 63 bonded to one side of the antenna 61, and a lower surface of the magnetic core member 63. A conductive material portion 64 is provided. The magnetic core member 63 crosses a part of the antenna 61 on the other surface of the base substrate on which the antenna 61 is provided, one end of the antenna 61 protrudes outside the antenna 61, and the other end is the antenna. The layers are stacked so as to come to the center (inside) 62 of 61.
When the magnetic core member 63 is laminated in this way, the magnetic flux enters from one end of the magnetic core member 63 and exits from the other end, so that the magnetic flux emitted from the other end passes through the inside of the antenna 61. The induced electromotive force is generated in the antenna 61 formed by the conductor 61a. For this reason, even if this IC label is attached to the surface of the article 65 and the magnetic flux direction around the IC label becomes parallel to the antenna 61 surface of the IC label, the magnetic flux passes through the antenna 61. This induces a voltage sufficient to operate the IC chip, so that the IC chip operates reliably.

  Further, in this embodiment, since the conductive member 64 is laminated and adhered so as to cover the magnetic core member 63 on the other surface of the base substrate on which the antenna 61 is provided, the conductive member 64 transmits radio waves to the article. The passage will be blocked. Therefore, the antenna 61 is less affected regardless of whether or not the article 65 is made of metal, and even if the surface of the article 65 is made of metal, loss due to eddy currents or the like generated on the metal surface. Thus, even if the RFID tag is attached to the metal article 65, the RFID tag operates reliably.

However, in Patent Document 1, if the diameter of the antenna 52 is increased in order to increase the magnetic flux passing through the antenna 52 in order to increase the induced electromotive force, there is a problem that the thickness of the IC label increases.
On the other hand, Patent Document 2 has a problem that the thickness of the IC label increases in this case because the magnetic core member and the conductive member are provided on one surface of the base substrate.
Supervised by Nobuyuki Teraura, “Development and Application of RF Tags-Future of Wireless IC Chips”, First Edition, CMC Publishing, February 28, 2003, p121, Fig. 2 JP 2003-317052 A JP 2003-108966 A

It can select from well-known things, such as a thing, and can use. Of these, an electrically insulating film or sheet made of polyethylene terephthalate (PET) or polyimide is preferably used.

The antennas 3 and 103 can be formed on one surface of the base substrates 2 and 102 by screen-printing in a predetermined pattern using polymer-type conductive ink or by etching a conductive foil.
Examples of the polymer-type conductive ink used in the present invention include resin particles containing conductive fine particles such as silver powder, gold powder, platinum powder, aluminum powder, palladium, rhodium and the like, and carbon powder (carbon black, carbon nanotube, etc.). In general, those blended in can be mentioned. If a thermosetting resin is used as this resin composition, a coating film can be obtained at 200 ° C. or less, for example, about 100 to 150 ° C., and the route through which the electricity of the obtained coating film flows is due to contact of conductive fine particles. However, a resistance value on the order of 10 ⁻⁵ Ω · cm can be obtained.
In addition to the thermosetting type, the polymer type conductive ink of the present invention may be a known type such as a photo-curing type, a penetration drying type, or a solvent volatile type. In addition, when a photocurable resin is included in the resin composition, the curing time can be shortened and the efficiency can be improved. Specifically, for example, a conductive resin fine particle is contained in an amount of 60% by mass or more, and a thermoplastic resin alone or a blend resin composition of a thermoplastic resin and a crosslinkable resin (particularly a crosslinkable resin composed of polyester and isocyanate) is used.

Examples thereof include an imparting agent, a thermoplastic elastomer-based flexibility imparting agent, a natural rubber-based flexibility imparting agent, a synthetic rubber-based flexibility imparting agent, and a mixture of two or more thereof.

  In the case where the antennas 3 and 103 are formed by etching, a material in which a copper foil is bonded to the entire surface of one surface of the electrically insulating base substrate 2 is prepared. Then, an etching resistant paint is printed on the copper foil in a desired pattern by a silk screen method. Since the antenna 3 is usually formed in a spiral shape or a rectangular shape, the etching resistant paint is printed in a spiral shape or a rectangular shape. Thereafter, the etching resistant paint is dried and solidified, and then immersed in an etching solution to dissolve and remove the copper foil not coated with the etching resistant paint, and the copper foil portion coated with the etching resistant paint is removed from the base substrate. The antennas 3 and 103 are formed so as to remain on one surface.

And the base materials 2 and 102 are bonded with an adhesive (not shown), and the antennas 3 and 103 and the IC chips 4 and 104 are electrically connected at the contact points provided on the back surfaces of the IC chips 4 and 104.

The composite comprising the magnetic layers 5 and 105 is coated with a magnetic coating material containing a binder and magnetic powder or magnetic flakes and dried, whereby the magnetic powder or magnetic flakes themselves are discretely formed. In addition, it is preferable that the magnetic coating material further includes an adhesive because it can enhance the binding property of the magnetic powder or the magnetic flakes and can be attached to an article.
Here, as the powder of the magnetic material to be included in the magnetic paint, carbonyl iron powder, atomized powder such as permalloy, reduced iron powder and the like are used. As the flakes of magnetic material, the above powder is refined with a ball mill or the like to form a powder, and then the flakes obtained by mechanically flattening the powder, or a molten iron-based or cobalt-based amorphous alloy is added to a water-cooled copper plate. Use flakes obtained by collision.

In the present embodiment, a thermoplastic resin, a thermosetting resin, a reactive resin, or the like can be used as the binder. Examples of the thermoplastic resin include vinyl chloride, vinyl acetate, vinyl chloride-vinyl acetate copolymer. Vinyl chloride-vinylidene chloride copolymer, vinyl chloride-acrylonitrile copolymer, acrylate ester-acrylonitrile copolymer, acrylate ester-vinyl chloride-vinylidene chloride copolymer, acrylate ester-vinylidene chloride copolymer, Methacrylic acid ester-vinylidene chloride copolymer, Methacrylic acid ester-vinyl chloride copolymer, Methacrylic acid ester-ethylene copolymer, Polyvinyl fluoride, Vinylidene chloride-acrylonitrile copolymer, Acrylonitrile-butadiene copolymer, Polyamide Resin, polyvinyl butyral, cellulose Conductor (cellulose acetate butyrate, cellulose diacetate, cellulose triacetate, cellulose propionate, nitrocellulose), styrene butadiene copolymer, polyurethane resin, polyester resin, amino resin, or styrene rubber, fluorine rubber, silicon Examples thereof include polymer synthetic rubber materials such as rubber and ethylene / propylene copolymer rubber.

  Using these magnetic paints, it may be applied by screen printing or the like so that the antennas 3 and 103 and the IC chips 4 and 104 are slightly hidden on one surface of the base substrates 2 and 102. It may be applied to the extent that it is hidden. After the magnetic layers 5 and 105 are applied, they are allowed to stand at room temperature, or heated to a predetermined temperature and time to solidify by drying, whereby the inlets 9 and 109 with the magnetic layers 5 and 105 are formed.

Subsequently, a release paper with discarded paper is prepared, and the inlet 9 is attached to one side of the released release paper through the magnetic layer 5 by removing the discarded paper.
Thereafter, an upper paper 8 having an adhesive layer 7 provided on the back surface thereof on the other surface (surface on which the antenna 3 and the IC chip 4 are not provided) of the base substrate 2 is interposed via the adhesive layer 7. By sticking, the second non-contact type data receiving / transmitting body of the present invention is obtained.

Hereinafter, the manufacturing method and manufacturing apparatus of the second non-contact type data transmitting / receiving body of the present invention will be described.
FIG. 3 is a diagram schematically showing a configuration of a second non-contact type data transmitter / receiver manufacturing apparatus according to an embodiment of the present invention. In the following, the inlet means an inlet with a magnetic layer.
The manufacturing apparatus according to the present embodiment includes first means 21 for supplying a first continuous paper 20 in which a paper sheet is pasted on a long release paper.
The first continuous paper 20 supplied from the first means 21 is sent to the third means 23 for attaching the inlet after the surface paper 20a is peeled off and wound up by the second means 22.
Below, the specific example of the 3rd means of FIG. 3 mentioned above is explained in full detail based on FIG.
As an example of the third means in FIG. 3, as shown in FIG. 4, there is a configuration including a stacker (holding means) 31, an inlet drawer (extraction means) 32, a moving means, and a moving pressing means.
[Holding means, removal means]
The third means 23 shown in FIG. 4 includes a stacker (holding means) 31 that holds a large number of inlets 30 (corresponding to 9 in FIG. 2) stacked in the vertical direction. Below the stacker 31, an inlet drawer 32 for taking out the inlets 30 one by one from the large number of inlets 30 is provided. The inlet drawer 32 is configured to be reciprocally movable along the vertical direction, and the leading end head 32a sequentially draws out (takes out) the inlets 30 positioned at the lowermost side of the multiple inlets 30 stacked on the stacker 31 by a suction action. .

[Removal means]
Here, the lower surface of the inlet 30 is a surface that is affixed onto the release paper 20b of the first continuous paper 20, and is formed flat. Therefore, the tip head 32a of the inlet drawer 32 can suck the central portion of the lower surface of the inlet 30 with a sufficient suction force, and the inlets 30 can be reliably pulled out one by one from the stacker 31. At this time, the inlet 30 bends instantaneously. However, since the IC module and the antenna are positioned away from the central portion of the inlet 30, they are not damaged by the suction of the tip head 32a. Moreover, since it is the structure which pulls out sequentially from the lowest side of many inlets 30, the inlet 30 can be supplied to the stacker 31 at any time also in the middle of work.

[transportation]
The inlet 30 drawn from the stacker 31 by the inlet drawer 32 is placed in a guide groove 33 a formed in the rail member 33. The width dimension of the guide groove 33a is set slightly larger than the corresponding dimension of the inlet 30. And the inlet drawer 32 is comprised so that it can approach the stacker 31 through the through-hole 33b of the perpendicular direction formed in the rail member 33. As shown in FIG. The third means 23 includes an extrusion block 34 that is positioned in the guide groove 33a of the rail member 33 and can reciprocate along the guide groove 33a.

  For example, the push block 34 driven by an air cylinder moves to the right side in the drawing along the guide groove 33a, thereby pulling the inlet 30 pulled out of the stacker 31 and placed in the guide groove 33a at its tip. Is fed until it substantially comes into contact with the abutting portion 33c of the guide groove 33a. Thus, the rail member 33 and the pushing block 34 constitute moving means for moving the inlets 30 taken out from the many inlets 30 to a predetermined position. Further, the stacker (holding means) 31, the inlet drawer (extraction means) 32, the rail member 33, and the pushing block 34 (moving means) selectively take out the inlets 30 one by one from a large number of inlets 30 and are predetermined. The feeding means for sequentially feeding to the positions is configured.

[Movement pressing means]
Further, the third means 23 is provided with a suction block 35 for sucking and gripping the inlet 30 positioned so that the tip substantially contacts the abutting portion 33c of the guide groove 33a by suction. The suction block 35 has a cubic shape corresponding to the rectangular shape of the inlet 30, and a sponge 35 a as a cushioning material is attached to the lower side surface of the suction block 35. A suction port (not shown) for sucking and holding the inlet 30 is provided at the center of the lower surface of the suction block 35.

  For example, the suction block 35 driven by an air cylinder is configured to be movable in the vertical direction and in the horizontal direction along the guide groove 33a. In this way, the suction block 35 is lowered toward the inlet 30 positioned so that the tip substantially contacts the abutting portion 33 c of the guide groove 33 a, and the inlet 30 is sucked and held on the lower surface of the suction block 35. At this time, the suction force from the suction block 35 acts on the central portion of the inlet 30, but the inlet 30 is not damaged due to the suction force due to the buffering action of the sponge 35 a.

  The suction block 35 that sucks and holds the inlet 30 moves up and then moves to the upper side of the release paper 20b of the first continuous paper 20 along the horizontal direction in the drawing. At this time, the suction block 35 moves laterally along a horizontal guide (not shown), and stops at a predetermined position above the release paper 20b by the action of a stopper (not shown), for example. Thereafter, the suction block 35 is lowered and presses the inlet 30 gripped and held against the surface of the release paper 20b.

  The first continuous paper 20 has the release paper 20b exposed with the discarded paper 20a peeled off. Therefore, when the suction block 35 presses the inlet 30 against the surface of the release paper 20b and stops the suction operation, the inlet 30 is attached to the surface of the paper 20b. In this way, the suction block 35 constitutes a moving pressing means that moves the inlet 30 fed to a predetermined position and sequentially presses the surface of the release paper 20b of the first continuous paper 20.

  On the other hand, the first continuous paper 20 is intermittently conveyed along the longitudinal direction by a sensor (not shown) reading a timing mark 20d formed on one side of the surface of the release paper 20b. In this way, by repeating the above-described inlet pasting operation and intermittent conveying operation, the inlets 30 are sequentially pasted on the surface of the release paper 20b at predetermined intervals.

  4 shows only one inlet pasting mechanism including one feeding unit and one moving pressing unit for the sake of clarity, the flow direction (supply direction) of the continuous paper 20 is shown. It is also possible to arrange the inlet pasting mechanisms along a plurality of rows. In this case, the same number of inlets 30 as the number of inlet sticking mechanisms can be simultaneously stuck on the surface of the release paper 20b.

  Further, the intervals along the flow direction of the first continuous paper 20 of the plurality of inlet pasting mechanisms can be adjusted so that the intervals between the plurality of inlets 30 stuck simultaneously on the surface of the release paper 20b can be adjusted. It is preferable that Furthermore, a plurality of inlet pasting mechanisms can be configured so as to be compatible with various sizes of inlets 30.

  Referring to FIG. 3 again, the first continuous paper 20 to which the inlets 30 are sequentially pasted at intervals through the third means 23 is transferred to the fifth means 27 composed of a pair of sticking rollers 27a and 27b. Sent. On the other hand, the manufacturing apparatus according to the present embodiment includes the fourth means 25 for supplying the second continuous paper 24 as the second continuous paper 24, for example, the second continuous paper 24 in which the waste paper is affixed to the upper paper via an adhesive layer. Yes. The second continuous paper 24 has a three-layer structure, and a discard paper 24a provided on the upper side and an upper paper 24b provided on the lower side are bonded together with an adhesive layer. Here, the upper sheet 24b constitutes a front sheet of the non-contact type data receiving / transmitting body 1.

  The second continuous paper 24 supplied from the fourth means 25 is sent to the fifth means 27 after the discarded paper 24 a is peeled off and taken up by the winding means 26. Note that the adhesive layer is exposed on the surface of the second continuous paper 24b (the surface in contact with the paper waste 24a) with the paper waste 24a peeled off. Thus, in the fifth means 27, the release paper 20b and the second continuous paper 24b pass between the pair of sticking rollers 27a and 27b, so that the adhesive layer of the second continuous paper 24b and the release paper 20b The surface on which the inlet 30 is pasted is superimposed and pasted.

  Here, in order to reduce the load on the inlet 30 when passing between the pair of sticking rollers 27a and 27b, that is, in order to reduce the nip pressure acting on the inlet 30, the sticking rollers 27a and 27b. A sponge (not shown) as a cushioning material is wound around at least one of them. Further, in each guide roller provided on the downstream side of the sticking means 27, in order to reduce the bending stress acting on the inlet 30 having a characteristic that is relatively weak to bending deformation, the roller diameter is set to a relatively large value (for example, (Diameter of about 80 mm).

  The composite paper (20b, 24b) that is superimposed and pasted via the fifth means 27 is sent to the sixth means 28. In the sixth means 28, an unnecessary portion of the composite paper (20b, 24b) that has been die-cut along the outer shape of one non-contact type data receiving / transmitting body (non-contact type data receiving / transmitting body region) The other release paper 20b and the paper 24b) are wound around the winding means 29.

As described above, in the present embodiment, the third means 23 selectively takes out the inlets 30 one by one from the large number of inlets 30 and sequentially feeds them to a predetermined position. By moving 30 and pressing the surface of the release paper 20b of the first continuous paper 20, the magnetic material layer has adhesiveness, so that it can be applied in sequence. Therefore, the operation of incorporating the inlet 30 into the paper can be automatically performed without relying on manual work, and a large amount of the non-contact type data receiving / transmitting body 1 can be manufactured efficiently and with high quality.
In addition, although FIG. 4 of this embodiment is supplying the inlet 30 with a cassette type, of course, you may take the system supplied with a continuous type and cut | disconnecting with a cutter etc. FIG. The magnetic layer may be formed by in-line coating and drying.

  The above-described apparatus for manufacturing a contactless data receiving / transmitting body can be similarly applied to a so-called IC tag. Therefore, the “non-contact type data receiving / transmitting body” in the present invention is not limited to a normal type non-contact type data receiving / transmitting body used by being peeled off from the mount, and is incorporated between two sheets of paper. The present invention can also be applied to an IC tag having a different form.
