Rfid label and pasting method of rfid label

The present invention relates to a label to be attached to an article, and more particularly to an RFID label having a so-called RFID tag provided with a memory chip for storing various information and a method for attaching the RFID label.

In recent years, as shown in FIG. 7, various tags called RFID (Radio Fruquency IDntification) tags T, which have a memory chip Ta for storing various information and a communication antenna Tb connected to the memory chip Ta, are used. A technique for automatically identifying non-contact wirelessly by attaching it to a label L attached to an article and using this RFID tag T has become widespread. FIG. 7 shows a label L to which the RFID tag T is attached. The label L is composed of a display layer U and an adhesive layer B, and the RFID tag T is attached to the back surface of the display layer U. It is temporarily worn in order. The RFID tag T is composed of an IC chip Ta and a communication antenna Tb, and is protected by a film layer J that covers the entire RFID tag T. As a label affixing device for affixing a label L to which an RFID tag T is attached to an article, for example, a label affixing device previously proposed by the applicant of the present application is known (Japanese Patent Laid-Open No. 2005-104521). Published). In this method, the label L is temporarily attached to the mount D and transported, and the label L peeled off from the mount D is adsorbed at a predetermined suction position by the suction plate, and the label L sucked by the suction plate is sucked at the predetermined sticking position. It is attached to the article.

Further, for a label to which an RFID tag is conventionally attached, for example, a label L as shown in FIG. 8 has been developed in order to keep the communicable distance constant. This label L is entirely foldable, for example, divided into three areas 110,111,112, one of which is equipped with a memory chip Ta and a communication antenna Tb, and the other area 111,112 is equipped with an antenna Tb, for example. , Each area 110, 111, 112 is bent and attached to the three surfaces constituting the corner of the article so that the communication conditions can be similarly applied in the three directions (for example, Japanese Patent Application Laid-Open No. 2003). -Published in Gazette No. 212348).

However, in the above-mentioned conventional label L, although it differs depending on the frequency, in particular, in the UHF band RFID tag T, the material and contents of the article to which the label L is attached obstruct electromagnetic waves, for example, a liquid such as metal or water. If the label contains, the electromagnetic wave may be absorbed by the article due to the influence of the metal or liquid of the article, or the electromagnetic wave may be disturbed by the diffused reflection, so that the information of the memory chip Ta may not be read / written by the reader / writer. was there.

In order to solve this, for example, as shown in FIG. 9, the label L is attached to the article W via the tubular hollow object 100, a gap 101 is provided between the label L and the article W, and an RFID tag is provided. It is effective to separate T from the article W and suppress the influence from the article W as much as possible (see, for example, Japanese Patent Application Laid-Open No. 11-240523).

<p> However, in order to attach the label L of Patent Document 3 to the article, the label L must be attached to the article W via the tubular hollow object 100, and the tubular hollow object 100 must be prepared separately. There is a problem that does not become. Further, as a method of fixing the label L of Patent Document 3 to the article, after the label L is attached to the tubular hollow object 100, in order to fix the tubular hollow object 100 to the article, an adhesive, cellophane tape or the like is used. When the above-mentioned fixing method is used for human work, there is a problem that the work is troublesome and the work efficiency is not good because it must be fixed to the article by using the above-mentioned conventional labeling device. Further, since the label L is attached to the article via the tubular hollow object 100, the tubular hollow object 100 may come off when the tubular hollow object 100 is rubbed against another object, or the tubular hollow object 100 may be removed. When the articles to which the label is attached are stacked, there may be a problem that the tubular hollow object 100 cannot be tilted and loaded.</p><p> The present invention has been made in view of the above problems, and in a label to which an RFID tag is attached, the RFID tag can be separated from the article and attached to the article without using a special member, and the label can be attached to the article.

Hereinafter, the label according to the embodiment of the present invention will be described in detail with reference to the accompanying drawings. 1 and 2 show the label L according to the first embodiment of the present invention. The label L has an adhesive layer B coated with an adhesive on the back surface side of the display layer U, and is temporarily attached to the strip-shaped mount D on the back surface side. An RFID tag T is attached to the back surface of the display layer U. The RFID tag T is composed of an IC chip Ta and a communication antenna Tb, and is protected by a film layer J that covers the entire RFID tag T. The label L is formed in a convex shape along the longitudinal direction R of the mount D, and is in the middle of one side 3 in which a rectangular tag attachment portion 1 of a predetermined size to which the RFID tag T is attached is continuously provided to the general portion 2. A partition line P is provided at the boundary between the tagged attachment portion 1 and the general portion 2, and as shown in FIG. 1, this partition line P is provided at the corner portion Wc composed of one plane Wa and the other plane Wb of the article W. At the same time, the general portion 2 is attached to the flat surface Wa, and the tag attachment portion 1 is attached in a state of protruding from the article W.

The display layer U is made of a material and a thickness having rigidity such that the tag attachment portion 1 projects from the corner portion Wc of the article W and can maintain the posture. Specifically, in the case of a paper base material formed of, for example, high-quality paper, art paper, coated paper, etc., the display layer U is formed to have a thickness t of t = 70 μm or more, and is made of polyethylene (PE), polypropylene ( In the case of resin film base materials such as PP), polyethylene terephthalate (PET), polystyrene (PS), polyurethane, and synthetic paper base materials processed into fibrous form such as paper by adding a filler to polyethylene, polypropylene, etc. It is desirable that the thickness t is formed to be t = 50 μm or more.

Further, the back surface of the tag attachment portion 1 is configured so that no adhesive is applied. This is because a notch having the same shape as the tag attachment part 1 is made in the mount D so that the tag attachment part 1 does not adhere to the part of the article W, and the tag attachment part 1 and the mount D can be projected in a temporarily attached state. To do. Alternatively, the adhesive may be applied in a halftone dot shape, but by adopting a configuration in which the adhesive is not applied to the back surface of the tag attachment portion 1, the tag attachment portion 1 is applied to another part of the article W, for example, an article. Since it is possible to prevent the W from adhering to the other flat surface Wb or the like, the tag attachment portion 1 can be reliably projected from the article W.

FIG. 3 shows the label L according to the second embodiment of the present invention. This label L is configured in substantially the same manner as the label L according to the first embodiment, but unlike the label L of the first embodiment, the tag attachment portion 1 is flush with the general portion 2. Sheet-shaped reinforcing base materials Ka and Kb are provided so as to have rigidity that allows the article W to protrude from the corner portion Wc in the state. The reinforcing base material Ka is formed to have the same size as the display layer U and is adhered to the display layer U. The RFID tag T and the adhesive layer B are provided on the back surface of the reinforcing base material Ka. The reinforcing base material Kb is provided only on a part of the tag attachment portion 1 and the general portion 2 connected to the tag attachment portion 1, and is provided on the back surface side of the RFID tag T. The reinforcing base materials Ka and Kb are composed of, for example, a resin film base material or a synthetic paper base material, and when the tagging portion 1 is provided so as to project, the rigidity for holding the posture is increased, and the external parts are increased. The function to protect the RFID tag T from the impact from is improved.

Further, the back surface (reinforcing base material Kb) of the tag attachment portion 1 is not coated with an adhesive. As with the label L according to the first embodiment, it is possible to prevent the article W from adhering to the other flat surface Wb or the like, so that the tag attachment portion 1 can be reliably projected from the article W.

Although the configuration of the label L according to the second embodiment has been described using the reinforcing base materials Ka and Kb, the reinforcing base material Kb may be omitted and only the reinforcing base material Ka may be configured, or the reinforcing group may be used. The material Ka may be omitted and only the reinforcing base material Kb may be used, which may be changed as appropriate.
