1. Field of the Invention
The present invention relates to an apparatus and a method for producing a sheet material to be attached to an article, the sheet material covering a tag to/from which information can be written/read in a non-contact state.
2. Description of the Related Art
In order to manage articles and the like, for example, there is employed a so-called radio frequency identification (RFID) tag which contains an integrated circuit (IC) and an antenna that are electrically connected to each other, and to/from which information can be written/read in a non-contact state.
As an example of a conventional RFID label having the RFID tag of this type, JP 2000-222545 A, for example, discloses an RFID label which includes film materials bonded to the RFID tag. In the conventional RFID label, both surfaces of the RFID tag are covered with the film materials, one of the film materials having a printing layer formed thereon, the other of the film materials having an adhesive layer formed thereon.
Further, the conventional RFID label is produced into a label form by use of an apparatus for producing a label, and then desired information is written into the IC of the RFID tag with an RFID tag writer. Information such as characters and barcodes a reprinted on a printing layer with a printing device, and the RFID label is attached to an article through the adhesive layer to be used. The conventional RFID label is relatively expensive, but is thrown away after one use because of being difficult to reuse the RFID tag by peeling the RFID tag off from the RFID label.
In place of the conventional RFID label, there is widely used an RFID label having an RFID tag which contains an IC and an antenna that are coated with a resin material, has various types such as a card type, a coin type, and a stick type, and which can be reused. The RFID tag of this type has an inconvenience in that information written in the IC cannot be confirmed with eyes. Accordingly, it is necessary to separately prepare a display member such as a printing sheet or a printing label on which information is printed, and to use the RFID tag in combination with the display member. Further, in a case of using the RFID tag of this type, it is necessary to attach the RFID tag to an article. Accordingly, for example, a case for receiving the RFID tag is stuck to the article, and the display member on which information has been printed is received in the case with the RFID tag, thereby being used for managing the article.
Incidentally, as described above, in the case of using the conventional RFID tags of various types such as the card type, the coin type, and the stick type, the RFID tag and the display member on which information of the RFID tag has been printed are handled separately. For this reason, when the RFID tag and the display member are erroneously matched with each other, there is a fear that the information of the RFID tag and the information of the display member do not match with each other in some cases.
Further, in the case of handling the RFID tag, it is necessary to attach the above-mentioned case to the article, and to additionally provide a structure, such as the case, for attaching the RFID tag to the article. It is also necessary to change each structure for attaching the RFID tag and the display member to the article to adapt to the type of the RFID tag, the size of the display member, or the like. Thus, there is an inconvenience in that an operation of attaching the RFID tag to the article is complicated.
It is an object of the present invention to provide an apparatus and a method for producing a sheet material capable of producing a label of a desired type based on information read from a tag, thereby making it possible to match information of the tag with information printed on a sheet material with reliability, and to simply attach the tag to an article.
In order to achieve the above object, the present invention provides an apparatus for producing a sheet material to be attached to an article, the sheet material covering a tag which contains an antenna and an integrated circuit that are electrically connected to each other and are coated with a coating material, and to/from which information can be written/read in a non-contact state, the apparatus including: reading means for reading information from the tag; sheet supply means for supplying the sheet material having a printing layer on one surface of a sheet-type base material, and having a heat-sensitive adhesive layer on the other surface of the sheet-type base material; printing means for performing printing on the printing layer of the sheet material supplied from the sheet supply means; and thermal activation means for heating the heat-sensitive adhesive layer of the sheet material, which is printed by the printing means, to develop an adhesive force of the heat-sensitive adhesive layer. The apparatus for producing a sheet material also includes control means for controlling the thermal activation means to develop the adhesive force in a predetermined area of the heat-sensitive adhesive layer other than an area facing the tag so as to form an adhesive area to be attached to the article, and which controls the printing means to print predetermined information on the printing layer, based on the information read from the tag by the reading means.
In the apparatus for producing a sheet material according to the present invention with the above-mentioned structure, the control means controls each of the printing means and the thermal activation means based on the information read from the tag by the reading means, thereby printing the predetermined information on the sheet material and developing the adhesive force in the predetermined area of the sheet material, based on the information of the tag. As a result, a label of a desired type can be easily produced based on the information read from the tag, thereby making it possible to match the information of the tag with the information printed on the sheet material with reliability, and to simply attach the tag to the article with the sheet material.
Further, the thermal activation means of the apparatus for producing a sheet material according to the present invention may form, on the heat-sensitive adhesive layer, a first adhesive area to be attached to an article, and a second adhesive area in which the sheet material is folded back to be bonded so as to hold the tag.
Further, the printing means of the apparatus for producing a sheet material according to the present invention may perform printing of duplicate information on the first printing area position on the back surface of the first adhesive area and on the second printing area positioned on the back surface of the second adhesive area. As a result, for example, in a case where the RFID tag is collected from the article, even when the first printing area attached to the article and the second printing area are separated from each other, the printed information can be shared between the first printing area and the second printing area.
The present invention also provides a method of producing a sheet material for attaching a tag to an article, the tag containing an antenna and an integrated circuit that are electrically connected to each other and are coated with a coating material, and to/from which information can be written/read in a non-contact state. The method of producing a label includes the steps of: reading information from the tag; supplying the sheet material having a printing layer on one surface of a sheet-type base material, and having a heat-sensitive adhesive layer on the other surface of the sheet-type base material; developing an adhesive force in a predetermined area of the heat-sensitive adhesive layer other than an area facing the tag so as to form an adhesive area to be attached to the article, based on the information read from the tag; and printing predetermined information on the printing layer based on the information read from the tag.
According to the present invention as described above, the adhesive force is developed in the predetermined area of the heat-sensitive adhesive layer and the predetermined information is printed on the printing layer, based on the information read from the tag. As a result, a label of a desired type can be produced based on the information read from the tag, thereby making it possible to match the information of the tag with the information printed on the sheet material with reliability, and to simply attach the tag to the article with the sheet material.
In the accompanying drawings:
Hereinafter, exemplary embodiments of the present invention will be described with reference to the drawings.
An apparatus for producing a sheet material according to an embodiment of the present invention is an apparatus for producing a sheet material to be attached to an article in a state where a so-called RFID tag, which contains an antenna and an IC electrically connected to each other and to from which information can be written/read through a non-contact communication using a radio wave, is covered. For the RFID tag according to the embodiment, there are employed RFID tags of various types such as a card type, a coin type, and a stick type, each of which contains the IC and the antenna coated with a resin material or the like, and which can be reused by rewriting information stored in the IC. The sheet material used in the embodiment includes a sheet-type base material, a heat-sensitive printing layer formed on one surface of the sheet-type base material, and a heat-sensitive adhesive layer formed on the other surface of the sheet-type base material.
As shown in
The RFID tag reader 11 includes a communication circuit (not shown) for writing and reading information through a non-contact communication with respect to the IC of the RFID tag, and the communication circuit is electrically connected to the control unit 16. Note that the information read from the IC of the RFID tag by the RFID tag reader 11 contains information on various types of the RFID tag, such as a card type, a coin type, and a stick type, and information to be printed on the heat-sensitive printing layer.
The sheet supply unit 12 includes a spindle 12b for rotatably supporting a sheet supply roll 12a, which is formed of a continuous form sheet material 4 wound into a roll, and a drive mechanism (not shown) for rotationally driving the spindle 12b.

Description is given of operations for producing a sheet material used as an RFID label in the sheet material production apparatus 1 having the structure described above.
First, in the sheet material production apparatus 1, information recorded on the IC of the RFID tag is read by the RFID tag reader 11. The information read by the RFID tag reader 11 is sent to the control unit 16. Subsequently, as shown in
Then, the control unit 16 determines an optimum type of the RFID label and an optimum length of the sheet material 4 in a transport direction, based on results of the above-mentioned selection (Step 104). Subsequently, the control unit 16 controls the printing unit 13 to print given information on the heat-sensitive printing layer of the sheet material 4 (Step 105), and controls the cutting unit 14 to cut the sheet material 4 with a predetermined length (Step 106). After that, the control unit 16 controls the thermal activation unit 15 to heat a predetermined area of the heat-sensitive adhesive layer of the sheet material 4 to develop the adhesive force thereof (Step 107).
Finally, the RFID tag is attached to a predetermined position on the heat-sensitive adhesive layer of the sheet material 4. The sheet material 4 is folded back so as to form a bag-like receiving portion for receiving the RFID tag, and the folded portions of the heat-sensitive adhesive layer are bonded together, thereby composing the RFID label (Step 108). The RFID label thus obtained has the RFID tag held in the bag-like receiving portion formed of the sheet material 4. The RFID label is to be attached to an article to be used in a state where the RFID tag is covered to be held.
Next, description is given of the RFID label composed using the sheet material 4 produced by the sheet material production apparatus 1 of the embodiment, with reference to the drawings.
As shown in
The first adhesive area 41 is positioned on one edge side of the sheet material 4, which is supplied from the sheet supply unit 12, in the transport direction. The second adhesive area 42 is positioned on the other edge side of the sheet material 4 in the transport direction, and is provided in an area other than an area facing the RFID tag 3. The second adhesive area 42 is formed with a predetermined width along both sides of the sheet material 4 in the width direction orthogonal to the transport direction. The sheet material 4 has a bag-like receiving portion with one edge side being opened, which is formed by folding back the second adhesive area 42 to be bonded. As a result, it possible to easily take out the RFID tag 3 from the opening of the receiving portion.
As shown in
As shown in
On the first printing area 43, for example, date., a product name, and a barcode and a two-dimensional barcode which include those pieces of information are printed. On the second printing area 44, for example, information on date, a manufacturer name, a product name, quantity, and the like, and a barcode and a two-dimensional barcode which include those pieces of information are printed. Further, duplicate printing of a part of those pieces of information, such as a barcode and a two-dimensional barcode, on the first printing area 43 and the second printing area 44, enables sharing of the printed information between the article side and the RFID tag 3 side, even in a case where the portion corresponding to the first printing area 43 attached to the article and the portion corresponding to the second printing area 44 holding the RFID tag 3 are separated from each other when the RFID tag 3 is collected, for example, after the use of the RFID label 5.
In other words, in the case of the RFID label 5, when the RFID tag 3 is separated from the portion corresponding to the first printing area 43 together with the portion corresponding to the second printing area 44, the portion corresponding to the first printing area 43, is left on the article to which the RFID label 5 is attached. Accordingly, the information such as barcodes and characters printed on the first printing area 43 can be left on the article. The portion corresponding to the first printing area 43 of the RFID label 5 is left on the article in this manner, thereby making it possible to make an inquiry on various necessary information only from the article on hand, and to follow a delivery route or the like of the article.
The RFID label 5 is formed as an RFID label of a so-called case type for holding the RFID tag 3 by folding back the sheet material 4 to be bonded in a bag shape. Alternatively, the RFID label 5 may be formed as an RFID label of a so-called cover type to be attached to an article in a state where the RFID tag 3 is covered with the sheet material 4 which is not, folded back.
As shown in
As shown in
As shown in
The structure of the RFID label 6 of the cover type produced in the above-mentioned manner is simplified as compared with the RFID label 5 of the case type.
Finally, description is given of a modified example of the RFID label 5 of the case type with reference to the drawings.
As shown in
Note that the thermal activation head 15a of the thermal activation unit 15 selectively heats the heat-sensitive adhesive layer of the sheet material 4 in units of dots so as to change the density of the area in which the adhesive force is developed, thereby enabling control of the magnitude of the adhesive force developed in the heat-sensitive adhesive layer. In addition, the thermal activation unit 15 adjusts the size of the adhesive area of the heat-sensitive adhesive layer, in which the adhesive force is developed, and adjusts the shape of the adhesive area, thereby enabling control the magnitude of the adhesive force. Accordingly, in order to easily remove the RFID tag 3 from the heat-sensitive adhesive layer when the RFID label 5 is decomposed, the thermal activation unit 15 may adjust the magnitude of the adhesive force to be varied for each adhesive area of the heat-sensitive adhesive layer such that the adhesive force of the third adhesive area 47 for temporarily fixing the RFID tag 3 becomes smaller than that of the first adhesive area 41 to be attached to an article and that of the second adhesive area 42 in which the sheet material 4 is folded back to be bonded.
Further, as shown in
Further, if necessary, as shown in

Further, if necessary, as shown in
As described above, in the sheet material production apparatus 1, the control unit 16 controls each of the printing unit 13, the cutting unit 14, and the thermal activation unit 15 based on the information read from the RFID tag 3 by the RFID tag reader 11. As a result, the production of the RFID labels 5 and 6 of a desired type can be facilitated based on the information read from the RFID tag 3, the information of the RFID tag 3 can be matched with the information printed on the sheet material 4 with reliability, and the RFID tag 3 can be simply attached to an article with the sheet material 4.
Further, as regards the RFID labels 5 and 6 formed of the sheet material 4 produced by the sheet material production apparatus 1, it is possible to reduce the adhesive force of the heat-sensitive adhesive layer by reheating the heat-sensitive adhesive layer. As a result, the sheet material 4 which is folded back to be bonded can be easily separated and the RFID tag 3 can be easily taken out therefrom. Accordingly, with the sheet material production apparatus 1, the RFID labels 5 and 6 which can be easily decomposed can be produced, and the RFID tag 3 can be reused with ease.
In addition, in the sheet material production apparatus 1, printing is performed oh the heat-sensitive printing layer of a single sheet material 4, so the printing can be satisfactorily performed on the heat-sensitive printing layer with flatness, and printing quality of the RFID labels 5 and 6 can be improved. Further, the heat-sensitive adhesive layer of the sheet material 4 is heated separately, thereby preventing heat and a pressing force from acting on the RFID tag 3 and securing an operation reliability of the RFID tag 3.
Note that the sheet material production apparatus 1 according to the embodiment of the present invention may have a structure further including an RFID tag writer for deleting information recorded on the IC of the RFID tag 3 and for recording additional information on the IC.
Further, the sheet material production apparatus 1 according to the embodiment may have a structure further including a tag attaching device (not shown) for attaching the RFID tag 3 at a predetermined position on the heat-sensitive adhesive layer of the sheet material 4.
