Description

  The present invention relates to an RFID label using electromagnetic waves for reading and writing data and a method for attaching the RFID label.

  In recent years, RFID (Radio Frequency ID), which is a technology for reading and writing IC chips using radio, has been actively developed.

  FIG. 14 shows the operating principle.

The RFID 5 is an IC tag 4 (called an inlet) made of a thin film 3 with an IC chip 1 and an antenna 2 built therein, which is processed into a label (seal), a plastic card, a tag, and attached to an object to be managed, It is designed to be used by hanging.
A coil-shaped antenna 2 is connected to the IC chip 1 constituting the main part of the IC tag 4. When an electromagnetic wave from the reader / writer 6 hits the antenna 2, an electric current is generated. To receive data sent from the reader / writer 5 or to transmit information stored in its own memory wirelessly.

  The IC chip 1 has a built-in memory, and this memory usually has a system area that cannot be rewritten and a user data area that can be rewritten (some of which have no rewritable area).

  Since the information in the system area is unchanged, it cannot be counterfeited or copied, and is excellent in security. RFID uses various frequencies such as long waves of several hundred kilohertz, short waves of several tens of megahertz, UHF waves of several hundred megahertz, and microwaves of several gigahertz, which vary slightly from country to country. Depending on the frequency, the characteristics of communication distance, directivity, communication speed, noise, and radio interference differ, and it is necessary to select according to the purpose of use and the surrounding environment.

By the way, although it varies depending on the frequency, especially in UHF band RFID, electromagnetic waves are absorbed by metal or water, so if there is metal or water near the reader or IC tag, the information on the IC tag cannot be read or written. is there.
In order to solve this, it has been necessary to remove an obstructing object or use a special IC tag or frequency which is not affected.

  For example, Patent Document 1 discloses an RF-ID wristband in which an IC tag is held away from a human body by a predetermined thickness so that the communication distance is not shortened by absorption of electromagnetic waves into the human body. Has been.

  However, the wristband for RF-ID described in Patent Document 1 is unsuitable for printing and recording with a printer because the entire thickness is non-uniform and the center is thick.

  In addition, an RF-ID wristband is read and written on an IC tag by a person wearing it over a reader / writer or the like, whereas an RFID label attached to an article or the like always brings the article close to the reader / writer or the like. Since it is not always possible, the device for attaching the IC tag has to be further devised.

JP 2003-296675 A

  The present invention has been made in view of the above-described problems of the prior art. In the present invention, an RFID label is affected by the material and contents (metal, moisture, etc.) of a container or the like that is an object to be attached, and electromagnetic waves are generated. It is intended to be attached at a predetermined distance from the object to be pasted so that the communication distance is not shortened by absorption.

  In order to solve the above problems, the RFID label according to the first invention is characterized in that an IC chip for storing data and an antenna for transmitting and receiving the data in a contactless manner using electromagnetic waves are formed on a circuit board. The applied IC tag, the adhesive is applied to the back surface, both ends are attached to the object to be attached, the center is an IC tag holding part for attaching and holding the IC tag, and the belt-like shape is a print recording part adjacent thereto. The label base material, the folding part formed at the boundary between each label base part, the IC tag holding part and the print recording part, and the back surface of the label base material are temporarily attached to protect the adhesive application surface. And a release paper that is peeled off when affixed to the object to be adhered. Part Bonded by bending the paddle alignment, and formed into a substantially T-shape in which each application segment is open, it is to sticking from the surface of the object to be adhered to the IC tag holding unit rises.

  Here, the bent portion is one of a fold line printed on the label base material, a perforation perforated in the label base material, a narrow width portion partially processed to narrow the width of the label base material, or these It is preferable to select from a combination.

  Moreover, it is preferable that the release paper is formed with a perforation or a slit (cut) in the vicinity of or in the vicinity of at least one bent portion of the label base material.

  On the other hand, the RFID label sticking method according to the present invention is characterized by an IC tag in which an IC chip for storing data and an antenna for transmitting and receiving the data in a contactless manner using electromagnetic waves are formed on a circuit board, and a back surface. An adhesive is applied, both ends are attached to an object to be attached, an IC tag holding portion for attaching and holding the IC tag at the center, and a strip-shaped label base material which is a print recording portion adjacent thereto, and the label Each adhesive part of the base material, a bent part formed at the boundary of the IC tag holding part and the print recording part, and temporarily attached to the back surface of the label base material, protect the adhesive application surface and The RFID label composed of release paper to be peeled off when pasting, the respective pasting portions are folded back to the front side of the label base, the IC tag holding portion and the print recording portion are folded face to face, A process of forming a substantially T-shape with an attached portion, and affixing the RFID label so that the IC tag holder rises from the surface of the object to be adhered, or the level of a bottle filled with liquid It is either pasting or winding and pasting on the narrow neck part above, or pasting so that each pasting part straddles on the ridgeline of a box-shaped container.

  According to the configuration of the RFID label, since the IC tag holding portion and the print recording portion of the label base material are separate parts, the print recording can be performed by the printer without being disturbed by the unevenness and thickness of the IC tag. it can.

  Further, since the IC tag holding part is stuck so as to stand up from the surface of the sticking object, the IC tag can reliably receive the electromagnetic wave without being affected by the material and contents of the sticking object.

  In addition, if the bent portion is composed of a perforation perforated in the label base material or a narrow width portion in which the width of the label base material is partially narrowed, the portion to be folded can be easily understood and the label can be easily removed without shifting. The substrate can be folded and bonded together.

  On the other hand, if the bent portion is formed of a fold line printed on the label base material or a narrow width portion obtained by partially processing the width of the label base material, the risk of accidentally separating the label base material can be avoided.

  And when the perforation or slit (cut) is formed in the release paper so that it coincides with or near at least one bent portion of the label base material, the label base material can be bent along the portion where the release paper is easy to bend. It is possible to reduce the risk that the label base material is folded and pasted in a wrong position.

  Furthermore, in the sticking method of the present invention, the electromagnetic wave can be satisfactorily transmitted without sticking to other bottles or RFID labels by sticking or wrapping around the narrow neck above the liquid level of the bottle filled with liquid. Can receive.

  Further, the same effect as described above can be obtained by pasting the pasting portions on the ridge line of the bag-like container or box-like container.

  According to the present invention, it is possible to record on an RFID label by a printer without being obstructed by the unevenness and thickness of the IC tag holding portion.

  Further, the IC tag can reliably receive electromagnetic waves without being affected by the material or contents of the object. In addition, if the folding part is formed by perforations perforated in the label base material or narrow width parts in which the width of the label base material is partially narrowed, the folding part can be easily understood, and the label base can be easily removed. The material can be folded and bonded together, and if the folded part is composed of a fold line printed on the label base material or a narrow width part where the width of the label base material is partially narrowed, the label base can be misplaced. The danger of cutting off the material can be avoided.

  When the perforation or slit (cut) is formed in the release paper so that it coincides with or in the vicinity of at least one bent portion of the label base material, the label base material can be bent along the portion where the release paper is easily folded. The risk that the label base material is folded and pasted at the wrong position can be reduced, and at the same time, the risk of accidentally separating the label base material can be avoided.

  Then, in the sticking method of the present invention, it is possible to receive electromagnetic waves satisfactorily without interfering with other bottles or RFID labels by sticking or winding on the narrow neck portion above the liquid level of the bottle filled with liquid. The same effect can be obtained by pasting the pasting parts across the ridgeline of the box-shaped container.

Hereinafter, the best mode for carrying out the present invention will be described with reference to FIGS.
In addition, the same code | symbol is attached | subjected to the component same as the prior art mentioned above, and the description is abbreviate | omitted.

  In FIG. 1, 10 shows one unit of the RFID label according to the embodiment, and the RFID label 10 is a strip-shaped label base material 11 made of a single or composite material such as paper, plastic film, synthetic paper, and nonwoven fabric, It is generally composed of an adhesive 12 applied to the back surface of the label substrate 11, the IC tag 4 described above, and a release paper 19 having a surface coated with a release agent such as silicone.

  The label base material 11 has both ends in the extending direction serving as pasting portions 13 for pasting objects, and the center serving as an IC tag holding portion 14 for pasting and holding the IC tag 4 and a print recording portion 15 adjacent thereto. Yes. In the illustrated example, the adhesive material 12 is further applied to the back surface of the IC tag 4, but the adhesive material 12 on the back surface of the IC tag 4 may be omitted.

  Bending portions 17 and 18 made of perforations perforated in the label base material 11 are provided at the boundaries between the pasting portions 13 of the label base material 11, the IC tag holding portion 14 and the print recording portion 15. Reference numeral 16 denotes a print record of characters, symbols, barcodes, and the like printed on the surface of the print recording unit 15. The RFID label is printed on a printer, but may be recorded by handwriting or a stamp. Further, it may be by ink application or transfer, or by self-coloring or stamping. In the case of self-coloring, it is necessary to provide a structure such as a self-coloring layer on the label substrate 11 in advance.

  Reference numeral 19 denotes a release paper that is temporarily attached to the adhesive material 12 on the back surface of the label base 11 to protect the application surface of the adhesive 12 and to be peeled off when it is attached to an object to be applied. A detection mark (eye mark) 20 is printed with black ink at one end in the extending direction. The detection mark 20 is used as a mark for detecting the position by an optical sensor on the printer side when the RFID label 10 is printed by a printer.

  The RFID label 10 is handled as a continuous roll 21 as shown in FIG. 2 from the production / distribution process until it is set and recorded on the printer, and the release paper 19 is used as a carrier for the RFID label in the printer. Is also used. Before or after each detection mark 20 of the release paper 19 (after the example in the drawing), a cut line (perforation) 22 for cutting the RFID label 10 one by one is formed (in FIG. 2). The IC tag 4 is covered with a label base material and cannot be seen, but is displayed as a transmission diagram).

  The RFID label 10 is as described above. Next, a method for using (attaching) the RFID label 10 will be described. First, the RFID label 10 recorded in the print recording unit 15 by a printer or the like (recorded on the IC tag 4 using a reader / writer as necessary) is cut out by the cutting line 22 for each unit, and the release paper 19 is removed.

  Next, each of the pasting portions 13 is folded back to the front side of the label base material 11 by the folding portion 17, and the IC tag holding portion 14 and the print recording portion 15 are folded by the folding portion 18 and bonded face to face. Each of the pasting portions 13 is formed in a substantially T-shape and is pasted so that the IC tag holding portion 14 rises from the surface of the subject to be pasted (blood bag 23... Described later).

  Since the blood bag 23 as the object to be applied in the embodiment is blood containing a large amount of water, electromagnetic waves are absorbed by the blood bag 23 simply by attaching the RFID label 10 in a plane. Communication between IC tag 4 and reader / writer is not possible. In addition, since the blood bag 23 is easily deformed, there is a disadvantage that the antenna 1 and the like of the IC tag 4 are easily disconnected only by attaching the RFID label 10 in a plane. On the other hand, in addition to information determined at the time of collection, such as the collection date and time, the name of the donor, blood type, health status, and medical history, additional information such as storage history is also required, so a normal bar where records cannot be added or changed There was a problem that it was difficult to manage with code labels.

  However, according to the present embodiment, since the IC tag holding unit 14 and the print recording unit 15 of the RFID label 10 are provided in different parts adjacent to the label base material 11, the unevenness and thickness of the IC tag 4 can be reduced. Without being obstructed, it is possible to print and record the barcode 16 and the like by the printer. Further, since the IC tag holding part 14 is stuck so as to stand up from the surface of the blood bag 23 which is an object to be stuck, the IC tag 4 reliably receives electromagnetic waves without being affected by the material and contents of the blood bag 23. It is possible to add additional information and change information to the blood bag 23.

  In addition, since the bent portions 17 and 18 of the label base material 11 are constituted by perforations perforated in the label base material 11, it is easy to understand the place where the label base material 11 is bent, and the label base material 11 is bonded without shifting. be able to.

  And although the blood bag 23 is easy to deform | transform, since the RFID holding | maintenance part 14 is reinforced by laminating | stacking the label base material 11 doublely, the antenna 2 grade | etc., Of IC tag 4 is hard to be disconnected. It also has tools.

  Further, when the barcode 16 of the RFID label 10 is read by a touch scanner or a pen scanner, it is possible to bend the folding portion 17 so that the RFID label 10 is laid as shown in FIG.

Next, another sticking method will be described with reference to FIGS.
FIG. 6 is a view showing a state in which the blood bag 23 is attached to the edge of the blood bag 23 so as to straddle the two attaching portions 13 of the RFID label 10, and FIG. 7 is a cross-sectional view in the direction of arrows VII-VII in FIG. FIG. Although this embodiment has the same effects as described above, in particular, according to this embodiment, even when the blood bag 23 is suspended or stacked, the RFID labels 10 are ejected from between the blood bags to the outside. be able to. In this case, if the RFID label 10 and the blood bag 23 are attached while being shifted little by little along the edge of the blood bag 23, both the RFID label 10 and the blood bag 23 can be stored in a space-saving manner, and can reliably communicate with the IC tag 4 of each RFID label 10.

  FIG. 8 shows still another embodiment, which is characterized in that the affixing portion 13 of the RFID label 10 is affixed or wound around the narrow neck portion 26 above the liquid surface 25 of the bottle 24 filled with liquid. The bottle 24 may be a glass bottle, ceramic, porcelain, metal, plastic bottle or the like. The liquid may be a sample, a reagent, or the like, or a seasoning or liquor. With the above configuration, the RFID label 10 does not interfere with the storage of the bin 24, and the electromagnetic wave is not absorbed by the liquid. Further, even if the bottle cap (lid or stopper) 27 is made of metal or the like, the RFID label 10 is set apart from this, so that the IC tag 4 can be read / written reliably.

FIG. 9 shows still another embodiment, and rises from one side of the edge of a box-like container 28 containing a metal can or an object containing a large amount of moisture (for example, clay, meat, gel, etc.). Thus, the state pasted across the pasting part 13 is shown.
Also with the above configuration, substantially the same effect as the above-described embodiment can be obtained.

Next, FIG. 10 thru | or FIG. 13 is another embodiment about the bending part shape of an RFID label. In each case, a plurality of RFID labels are connected, but only two units are shown.
In the following description, (A) in each figure is a front view, and (B) is a cross-sectional view in the direction of arrow BB in each front view (A).

  In FIG. 10, the bent portions 17 and 18 of the RFID label 10 are formed by perforations, and the boundary between the RFID labels 10 is a cut line or slit 22 by the perforation for the release paper 19, and at this time, the boundary between the label base materials 11 Indicates an example in which a slit or perforated line is used, or both the release paper 19 and the label base material 11 are perforated lines. That is, at the boundary between the RFID labels 10, both the release papers 19 and / or the label base materials 11 are connected by perforations. The cut line 22 is printed with a scissors mark 29 for cutting.

  FIG. 11 is similar to FIG. 10 regarding the bent portions 17 and 18 of the label base material 11 of the RFID label 10, but the sewing machine is aligned with or near the position of the bent portion 17 (or 18) of the release paper 19. This is an example in which eyes or slits 30 are formed. In this case, it is easy to carry out with the release paper 19 temporarily attached when the label substrate 11 is folded at the folding portion 17 (18) after being cut into units of each RFID label. Convenience is greatly improved.

  FIG. 12 shows another embodiment characterized in that the bent portions 31 and 32 of the label base material 11 of the RFID label 10 are not perforated, but are formed by narrow width portions in which the width of the label base material 11 is partially narrowed. 13 is a perforation or slit 34 in the vicinity of or near the position of the bent portion 31 (or 32) of the release paper 19 with respect to the label substrate 11 processed in the same manner as FIG. Is an example of forming.

  As shown in each of the above examples, if the folding portion is formed by a perforation formed in the label base material 11 or a narrow width portion in which the width of the label base material is partially processed, the portion to be folded is easy to understand, The label base material 11 can be easily folded and bonded without shifting.

  In addition, if the bent portion is formed of a fold line printed on the label base material or a narrow width portion obtained by partially processing the width of the label base material, the risk of accidentally separating the label base material can be avoided.

  Furthermore, when a perforation or a slit (cut) is formed in the release paper 19 so as to coincide with or be adjacent to at least one bent portion of the label base material 11, the label base material is bent along a portion where the release paper is easily bent. This can reduce the risk of mistakenly attaching the label base material by folding it back, and at the same time avoiding the risk of accidentally separating the label base material. Moreover, if the release paper pieces separated by the slits are temporarily attached to the back surface when the label base materials 11 are separated from each other and bonded, the convenience of work is greatly improved.
