Description

  The present invention relates to an anti-counterfeit sheet manufacturing apparatus that manufactures an anti-counterfeit sheet in which a thread is incorporated and forgery can be prevented by the thread.

  In the past, counterfeit crimes have frequently occurred in securities such as prepaid cards, various admission tickets, gift certificates and stock certificates because they are widely distributed and can be exchanged relatively easily. In particular, in recent years, with the improvement and popularization of copying machines such as color copiers, counterfeit products that cannot be easily distinguished from genuine products can be manufactured relatively easily, and countermeasures against counterfeiting are required. Yes. Moreover, measures against counterfeiting are required not only for the above-mentioned securities but also for banknotes.

  As one of countermeasures against such counterfeiting, a technique for preventing forgery of securities or banknotes by attaching a member called a thread to securities or banknotes or sandwiching them between paper base materials is considered. Yes. In this technology, a thread formed by cutting a plastic film, thin paper, etc. to a width of about several millimeters is not exposed from the surface of securities or banknotes, or securities such that a part is exposed from the surface. It is inserted between paper bases of banknotes, and authenticity of securities and banknotes is determined by the presence or absence of this thread.

  Furthermore, in recent years, a technique for determining the authenticity of securities and bills using a thread on which an IC chip capable of reading information in a non-contact state is mounted has been considered. In this technology, a thread in which an IC chip is bonded to one side of a film cut to a width of about several millimeters is sandwiched between securities and banknote paper bases, and when using securities and banknotes, an IC is used. By reading the information written on the chip, the authenticity of the securities or bills is determined (for example, see Patent Document 1).

  FIGS. 8A and 8B are diagrams showing an example of a thread on which an IC chip is mounted. FIG. 8A is a view as seen from the surface, and FIG. Moreover, FIG. 9 is a figure which shows an example of the forgery prevention sheet | seat in which the thread | sled 110 shown in FIG. 8 was integrated, (a) is the figure seen from the surface, (b) is A- shown in (a).

  In this example, as shown in FIG. 8, an IC chip 111 capable of reading information in a non-contact state is mounted at a predetermined position on a belt-shaped resin layer 112, and these are bonded to each other by an adhesive (not shown). Has been configured. As shown in FIG. 9, the thread 110 configured in this manner is sandwiched between the label base material 121 and the paper base material 122, and the label base 121 has an adhesive surface between the label base material 121 and the paper base material 122. Thus, a forgery prevention sheet 120 in which the IC chip 111 is incorporated is configured.

  In the anti-counterfeit sheet 120 configured as described above, when the information written in the IC chip 111 is brought close to a readable reader / writer, the information written in the IC chip 111 is read and read. Based on the information, the authenticity determination of the forgery prevention sheet 120 is performed.

  FIG. 10 is a diagram for explaining a method of manufacturing the forgery prevention sheet shown in FIG.

  In the continuous thread as described above, the IC chip is mounted on the resin layer or sandwiched between a plurality of layers so that the IC chip pitch is constant. Therefore, a thread having a pitch corresponding to is adopted.

  However, when the ambient temperature or humidity changes, such as when heat treatment or humidification processing is performed after incorporating the continuous thread as described above into the continuous label base material and paper base material, or after incorporation, This change in temperature and humidity causes the continuous label base and paper base to expand and contract, so that when the continuous thread is cut after being incorporated into the continuous label base and paper base, the continuous In some cases, the shape of the thread expands to increase the pitch of the IC chip, and the IC chip is disposed in the cutting area. In this case, the IC chip is cut.

  Here, in order to avoid such a problem, the continuous label base material and the paper base as described above are used when or after the continuous thread is incorporated into the continuous label base material and the paper base material. It is conceivable to perform heat treatment or humidification treatment that restricts the expansion and contraction of the material, but in that case, a dedicated device for performing heat treatment or humidification treatment is required, and the continuous state as described above is also required. It is difficult to set conditions that regulate the expansion and contraction of the label substrate and the paper substrate.

  The present invention has been made in view of the problems of the prior art as described above, and when the continuous sheet expands and contracts when or after the continuous thread is incorporated into the continuous sheet. Even so, an object of the present invention is to provide an anti-counterfeit sheet manufacturing apparatus capable of avoiding cutting of an IC chip when the continuous thread is cut for each forgery-preventing sheet.

In order to achieve the above object, the present invention provides:
A first supply means for supplying a continuous sheet; a second supply means for supplying a continuous thread provided with an IC chip; and the continuous sheet supplied from the first supply means. Incorporating means for incorporating the continuous thread supplied from the second supplying means, and the continuous sheet and continuous thread are pulled out from the first and second supplying means, respectively. Conveying means for conveying a continuous sheet in which the thread is incorporated, and cutting means for cutting the continuous sheet conveyed by the conveying means into a single piece together with the continuous thread. In the forgery prevention sheet manufacturing apparatus,
The continuous means is arranged at a pitch corresponding to the pitch of the IC chip in the continuous thread on the continuous sheet conveyance path in which the continuous thread is incorporated by the conveying means, and the continuous means is the continuous state. A plurality of information reading means for reading information from the IC chip provided in a continuous thread before cutting in the cutting means;
The relative position of the IC chip provided on the continuous thread incorporated in the continuous sheet with respect to the cutting position in the cutting means can be read from the IC chip among the plurality of information reading means. Relative position detecting means for detecting by the number of information reading means ;
When the relative position of the IC chip detected by the relative position detecting means is deviated by a predetermined amount from a predetermined position, the conveying operation of the continuous sheet and thread in the conveying means is performed relative to the IC chip. It has a conveyance control means which stops in order to correct a position, It is characterized by the above-mentioned.

  In the present invention configured as described above, the continuous sheet is pulled out from the first supply unit by the conveying unit, and the continuous thread provided with the IC chip is pulled out from the second supply unit. In the assembling means, the continuous thread is incorporated into the continuous sheet. Thereafter, the continuous sheet in which the continuous thread is incorporated is conveyed to the cutting means for cutting the continuous sheet and the continuous thread by the conveying means. At that time, in the relative position detecting means, The relative position with respect to the cutting position in the cutting means of the IC chip provided on the continuous thread incorporated in the continuous sheet is detected, and the relative position of the IC chip detected by the relative position detection means is determined in advance. When a predetermined amount is deviated from the position, this is notified to the conveyance control means for controlling the conveyance operation of the continuous sheet and the continuous thread in the conveyance means. Then, the conveyance operation of the continuous sheet and the continuous thread in the conveyance unit is stopped by the control of the conveyance control unit.

  Thus, when the relative position with respect to the cutting position in the cutting means of the IC chip provided on the continuous thread incorporated in the continuous sheet is shifted from the predetermined position by a predetermined amount, the continuous sheet In addition, since the continuous thread conveyance operation is stopped, the continuous sheet expands and contracts when the continuous thread is incorporated into the continuous sheet or after it is incorporated, so that the continuous thread is incorporated into the continuous sheet. Even when the relative position with respect to the cutting position of the IC chip cutting means provided in the continuous thread is shifted before the IC chip arrangement position becomes the continuous sheet cutting position. The conveying operation of the continuous sheet and the continuous thread can be stopped, and the position where the continuous thread is incorporated into the continuous sheet can be corrected.

  As described above, in the present invention, the relative position with respect to the cutting position in the cutting means of the IC chip provided on the continuous thread incorporated in the continuous sheet is shifted by a predetermined amount from the predetermined position. In this case, since the conveying operation of the continuous sheet and the continuous thread is stopped, the continuous sheet expands and contracts when the continuous thread is incorporated into the continuous sheet or after the continuous sheet is incorporated. Even when the relative position with respect to the cutting position in the cutting means of the IC chip provided on the continuous thread incorporated in the continuous sheet is shifted, the arrangement position of the IC chip is the same as that of the continuous sheet. Before the cutting position is reached, the conveying operation of the continuous sheet and the continuous thread is stopped, and the continuous thread is assembled to the continuous sheet. Can be corrected write position, IC chips can be avoided that would be cut.

  In addition, an information reading unit is provided that reads information from an IC chip that is incorporated into a continuous sheet by the incorporating unit and is provided on a continuous thread before cutting in the cutting unit. In the case of detecting the relative position of the IC chip using the result of reading information from the IC chip, the IC chip is embedded in the thread or the continuous thread is sandwiched between the continuous sheets from the outside. Even if it is impossible to visually recognize, the relative position of the IC chip can be detected.

And a roller control unit 35. a transport control means for stopping.

  Below, the manufacturing method of the forgery prevention sheet in the forgery prevention sheet manufacturing apparatus comprised as mentioned above is demonstrated.

  First, the continuous label base material 21, paper base material 22, and thread 10 wound around the rollers 1a to 1c are pulled out and conveyed by the rotation of the rollers 1i and 1j, respectively.

  The continuous label base material 21 drawn out from the roller 1a has the release paper 23 attached to the adhesive surface peeled off by the roller 1d, the peeled release paper 23 is collected by the roller 1e, and the release paper 23 is peeled off. The label substrate 21 is conveyed between the rollers 1g and 1h.

  Further, the continuous paper base material 22 drawn from the roller 1b is guided between the rollers 1g and 1h by the roller 1f.

  Further, the thread 10 drawn from the roller 1c is conveyed between the rollers 1g and 1h, and is sandwiched between the continuous label base material 21 and the paper base material 22 which are conveyed between the rollers 1g and 1h. The label substrate 21 is fixed by the adhesive surface, and the continuous label substrate 21 and the paper substrate 22 are bonded to each other by the adhesive surface.

  The continuous label base material 21 and the paper base material 22 in which the continuous thread 10 is sandwiched by the rollers 1g and 1h are conveyed to the cutting unit 40 by the rollers 1i and 1j. In the information reading unit 33, information is read from the IC chip 11 mounted on the continuous sled 10 sandwiched between the continuous label base material 21 and the paper base material 22 via the reading antennas 31-1 to 31-7. Is read out. Here, in the information reading unit 33, information is read via the reading antennas 31-1 to 31-7 when the continuous label base material 21, the paper base material 22, and the thread 10 are cut by the cutting unit 40. Read operation is performed. In this control, for example, a timing mark indicating the timing at which the continuous label base material 21, the paper base material 22, and the thread 10 are to be cut is given to the continuous label base material 21. The continuous label base material 21, the paper base material 22, and the thread 10 are cut by the cutting unit 40 at the timing when the timing mark is read in (not shown), and the continuous label is read by the information reading unit 33. It is conceivable that the information is read out from the IC chip 11 mounted on the continuous thread 10 sandwiched between the base material 21 and the paper base material 22 through the reading antennas 31-1 to 31-7.

  FIG. 5 shows the relative position of the IC chip 11 with respect to the cutting position in the cutting unit 40 using the reading result from the IC chip 11 via the reading antennas 31-1 to 31-7 in the control unit 30 shown in FIG. It is a figure for demonstrating the detection method of a position, (a) is a figure which shows the state when the mounting pitch of IC chip 11 on the continuous thread | sled 10 is not changing, (b) is a continuous thread | sled. 10C is a diagram showing a state in which the mounting pitch of the IC chip 11 on 10 is widened, and FIG. 10C is a diagram in which the mounting pitch of the IC chip 11 on the continuous thread 10 is widened, It is a figure which shows the state which the relative position shifted | deviated.

As shown in FIG. 5, the mounting pitch of the IC chip 11 on the continuous thread 10 before being sandwiched between the continuous label base material 21 and the paper base material 22 is t ₀ , and the reading antenna 31- Assuming that the read width of 1-31-7 is s, the read antennas 31-1 to 31-7 are arranged at a pitch of (6t ₀ -s). Of the reading antennas 31-1 to 31-7, the reading antenna 31-7 located on the most downstream side in the conveying direction of the continuous label base material 21, the paper base material 22, and the thread 10 is a reading area. The interval W between the end of the cutting section 40 and the cutting position in the cutting section 40 is mounted on the cutting position on the upstream side in the transport direction of the continuous label base material 21, the paper base material 22 and the thread 10 and on the thread 10. If the distance from the IC chip 11 is t _a (see FIG. 1),
W = t ₀ -t _a
It is arranged to become.

  Therefore, the pitch of the IC chip 11 mounted on the continuous thread 10 sandwiched between the continuous label base material 21 and the paper base material 22 is the same as that of the continuous label base material 21 and paper on which the continuous thread 10 is continuous. When there is no change from the state before being sandwiched between the base materials 22, the information reading unit 33 reads the information at the timing when the continuous label base material 21, the paper base material 22, and the thread 10 are cut by the cutting unit 40. When the information reading operation is performed via the antennas 31-1 to 31-7, as shown in FIG. 5A, the IC chip 11 is connected via all of the seven reading antennas 31-1 to 31-7. The information is read out from.

  Further, the pitch of the IC chip 11 on the continuous thread 10 after being sandwiched between the continuous label base material 21 and the paper base material 22 is set so that the continuous thread 10 is continuous with the label base material 21 and the paper base. When the information reading unit 33 spreads from the state before being sandwiched by the material 22, the reading antenna 31-is read when the continuous label base material 21, the paper base material 22, and the thread 10 are cut by the cutting unit 40 in the information reading unit 33. When the information reading operation is performed via 1 to 31-7, the information is not read from the IC chip 11 via all of the seven reading antennas 31-1 to 31-7. For example, FIG. As shown in FIG. 3, the IC chip 11 is only connected via the five reading antennas 31-3 to 31-7 on the side close to the cutting section 40 among the seven reading antennas 31-1 to 31-7. So that Luo information is read.

  Thereafter, when the relative position of the IC chip 11 with respect to the cutting position in the cutting part 40 gradually shifts due to the spread of the pitch of the IC chip 11, as shown in FIG. 5C, the seven reading antennas 31- Information is read from the IC chip 11 only through the three read antennas 31-5 to 31-7 on the side closer to the cutting unit 40 among the first to third 31-7. When the deviation amount is integrated, when the continuous thread 10 sandwiched between the continuous label base material 21 and the paper base material 22 is cut by the cutting unit 40, the IC is placed at the cutting position. The chip 11 is disposed.

  Thus, the number of antennas 31-1 to 31-7 from which information is read from the IC chip 11 is sent to the relative position detection unit 34 as a read result, and the relative position detection unit 34 outputs the information from the information reading unit 33. Using the read result, the relative position to the cutting position in the cutting portion 40 of the IC chip 11 on the continuous thread 10 sandwiched between the continuous label base material 21 and the paper base material 22 is detected.

  When the relative position of the IC chip 11 detected by the relative position detector 34 deviates from a predetermined position by a predetermined amount, the roller controller 35 is notified of this, and the roller controller 35 detects the rollers 1i, 1j. Control for stopping the conveying operation of the continuous label base material 21, the paper base material 22, and the thread 10 is performed.

  FIG. 6 is a flowchart for explaining processing according to the relative position of the IC chip 11 with respect to the cutting position of the cutting unit 40 in the forgery prevention sheet manufacturing apparatus shown in FIGS. 3 and 4.

  In the information reading unit 33 in the control unit 30, the label base material 21, the paper base material 22, and the thread 10 are cut by the cutting unit 40 continuously via the reading antennas 31-1 to 31-7. Information is read from the IC chip 11 mounted on the continuous thread 10 sandwiched between the label base material 21 and the paper base material 22 (step S1).

  The relative position detection unit 34 is notified of the reading result in the information reading unit 33, and the relative position detection unit 34 detects the relative position of the IC chip 11 with respect to the cutting unit 40 based on the reading result in the information reading unit 33. The relative position is detected by using the number of reading antennas from which information is read from the IC chip 11 by the information reading unit 33 as described above. For example, in the present embodiment, as shown in FIG. 5C, when the number of reading antennas from which information is read from the IC chip 11 by the information reading unit 33 is less than 5, It is determined that the relative position with respect to the cutting unit 40 is shifted from the predetermined position by a predetermined amount.

  When the relative position detection unit 34 determines that the relative position of the IC chip 11 with respect to the cutting unit 40 is deviated from a predetermined position by a predetermined amount (step S2), the roller control unit 35 is notified accordingly. In the roller control unit 35, stop control of the conveying operation of the continuous label base material 21, the paper base material 22, and the thread 10 by the rollers 1i and 1j is performed (step S3).

When the conveyance operation of the rollers 1i and 1j is stopped by the control of the roller control unit 35, the supply and conveyance of the continuous label base material 21, the paper base material 22, and the thread 10 are stopped. The thread 10 is cut (step S 4), and the continuous label 10, the paper base 22, and the thread 10 are transferred to the continuous label base 21 and the paper base 22. The distance between the cutting position on the upstream side in the direction and the IC chip 11 mounted on the thread 10 is corrected to be t _a (see FIG. 1) (step S5).

  Thereafter, the rollers 1i and 1j are driven by the control of the roller control unit 35, and the supply and conveyance of the continuous label base material 21, paper base material 22, and thread 10 are resumed (step S6).

  The continuous label base material 21 and the paper base material 22 in which the continuous thread 10 is sandwiched are conveyed to the cutting unit 40 and cut into a single piece by the cutting unit 40, and the label base material 21, the paper base material 22, The anti-counterfeit sheet 20 in which the thread 10 is sandwiched between the two is produced. The anti-counterfeit sheet 20 cut into a single piece is then conveyed to a predetermined area by the conveyor 50.

  In this embodiment, the number of readout antennas is seven, and when the number of readout antennas from which information is read out from the IC chip 11 is less than 5, the relative position detection unit 34 performs IC Although it is determined that the relative position of the chip 11 with respect to the cutting part 40 is deviated by a predetermined amount from a predetermined position, these numbers are not limited to those described above, and the relative position of the IC chip 11 with respect to the cutting part 40 is If it is the structure which can stop rollers 1i and 1j before the IC chip 11 is arrange | positioned in the cutting position of the continuous label base material 21 and the paper base material 22 by the accumulated shift | offset | difference, Good.

  In this embodiment, the continuous label base material 21 is supplied from the roller 1a, the release paper is peeled off from the label base material 21 by the roller 1d, and the adhesive surface of the label base material 21 is exposed. The label base material 21 and the paper base material 22 are bonded to each other while the thread 10 is fixed by the above, but a continuous base material to which no adhesive is applied is supplied from the roller 1a, and the roller 1a and the rollers 1g and 1h are supplied. It is also conceivable that an adhesive is applied to the contact surface of the base material with the paper base material 22 and the base material and the paper base material 22 are bonded to each other while fixing the thread 10 with the adhesive.

  Further, the present invention is not limited to manufacturing a forgery prevention sheet in which the thread 10 is sandwiched between the label base material 21 and the paper base material 22 as shown in the above-described embodiment. A forgery prevention sheet in which the thread 10 is mounted on and bonded to the material 22 may be manufactured. The embodiment will be described below.
