About.

  In recent years, with the progress of the information-oriented society, information is recorded on a card, and information management and settlement using the card are performed. In addition, information is recorded on tags and labels attached to products and the like, and management of products and the like using these labels is also performed.

  In such information management using a card, tag, or label, a non-contact type IC equipped with an IC chip capable of writing and reading information in a non-contact state with respect to the card, tag, or label Cards, non-contact type IC tags, and non-contact type IC labels are rapidly spreading due to their excellent convenience.

  6A and 6B are diagrams showing the structure of a general non-contact type IC label. FIG. 6A is a diagram showing the internal structure, and FIG. 6B is a cross-sectional view taken along the line AA ′ shown in FIG. .

  As shown in FIG. 6, the non-contact type IC label in this configuration example includes an IC chip 211 on which a data can be written and read from the outside on a resin sheet 215 and an IC chip via a contact 214. A current is supplied to the IC chip 211 by electromagnetic induction from an information writing / reading device (not shown) provided outside and connected to the 211, and information is written to and read from the IC chip 211 in a non-contact state. Inlet 210 on which conductive antenna 212 is formed protects IC chip 211 and antenna 212 via adhesive layers 240a and 240b, and surface sheet 230 on which information is printed, and release paper 220 are stacked so as to be sandwiched by 220.

  In the non-contact type IC label 200 configured as described above, the release paper 220 is peeled off and attached to an article or the like by the adhesive layer 240b, and used in an information writing / reading device provided outside. By bringing them close to each other, a current flows through the antenna 212 due to electromagnetic induction from the information writing / reading device, and this current is supplied to the IC chip 211 so that the IC chip 211 is in contact with the IC chip 211 in a non-contact state. Information is written to the IC chip 211, or information written to the IC chip 211 is read by the information writing / reading device.

  Below, the manufacturing method of the non-contact type IC label 200 comprised as mentioned above is demonstrated.

  FIG. 7 is a view for explaining a method of manufacturing the non-contact type IC label 200 shown in FIG.

  First, for example, the antenna 212 is formed on the resin sheet 215 on the adhesive layer 240b of a continuous sheet in which the adhesive layer 240b is provided on one surface of the release paper 220, such as a double-sided tape. An inlet 210 on which an IC chip 211 is mounted is mounted (FIGS. 7A and 7B).

  Next, a continuous layer in which an adhesive layer 240a is provided on one surface of a top sheet 230, such as tack paper, on a sheet composed of a release paper 220 and an adhesive layer 240b on which an inlet 210 is mounted. The sheets are stacked from the surface on which the inlet 210 is mounted, and conveyed while being sandwiched by a pair of rollers (not shown), whereby both sheets are adhered by the adhesive layers 240a and 240b. As a result, the inlet 210 is sandwiched between the sheet made of the release paper 220 and the pressure-sensitive adhesive layer 240b and the sheet made of the top sheet 230 and the pressure-sensitive adhesive layer 240a (FIG. 7C).

  Thereafter, the sheet stuck so that the inlet 210 is sandwiched is cut into a predetermined size, thereby completing the non-contact type IC label 200 as shown in FIG.

  Here, in the above-described process, when the sheet composed of the release paper 220 and the adhesive layer 240b on which the inlet 210 is mounted and the sheet composed of the top sheet 230 and the adhesive layer 240a are conveyed while being sandwiched by a pair of rollers, The pair of rollers, and the surface sheet 230 and the release paper 220 that are in contact with the pair of rollers are charged to opposite polarities by the conveyance process while being sandwiched by the pair of rollers. Therefore, there is a possibility that the IC chip 211 of the inlet 210 sandwiched between the sheet made of the release paper 220 and the pressure-sensitive adhesive layer 240b and the sheet made of the top sheet 230 and the pressure-sensitive adhesive layer 240a may be destroyed by static electricity. In addition to such a non-contact type IC label 200, in a low dielectric sheet having a possibility of generating static electricity, if it is sandwiched and transported by a transporting member such as a pair of rollers, it is transported while being sandwiched. Therefore, there is a problem that dust adheres due to static electricity generated by charging.

By the way, as a device for neutralizing a charged sheet, a device that supplies a charge to a charged sheet and thereby electrically neutralizes the sheet has been conventionally used (see, for example, Patent Document 1). By using such an apparatus, if a charge is supplied to a sheet that is sandwiched and conveyed by a conveying member such as a pair of rollers after being separated from the conveying member, the sheet can be electrically neutralized.
JP 2002-289394 A

  However, as described above, in the case where the sheet is electrically neutralized by supplying an electric charge to the charged sheet, the sheet is reversely charged, that is, opposite if the electric charge corresponding to the charged state of the sheet is not supplied. There is a risk of being charged to the polarity of

  Therefore, it is conceivable to supply the electric charge according to the measurement result while measuring the charged state of the sheet after being separated from the conveying member. In this case, the charged state of the sheet in a state where the electric charge is supplied is measured. Therefore, there is a problem in that the charged state generated by the carrying process while being sandwiched cannot be measured accurately. In view of this, it is conceivable to separate the area for measuring the charged state from the area for supplying the charge with respect to the sheet sandwiched and conveyed by the conveyance member, but in that case, a corresponding space is required. In addition, it is conceivable to switch between charge supply and charge state measurement. In this case, however, there is a problem in that the efficiency of the original transport process is reduced.

  The present invention has been made in view of the problems of the conventional techniques as described above, and a sheet charged by being sandwiched between transport members when the sheet is sandwiched and transported between transport members, An object of the present invention is to provide a static eliminator that can surely eliminate static electricity without reducing processing efficiency in a space-saving manner.

In order to achieve the above object, the present invention provides:
A static eliminator that neutralizes a sheet sandwiched and conveyed by a conveying member,
Measuring means for measuring the amount of charged charge in a region of the conveying member spaced from the sheet;
A charge applying unit configured to apply a charge having the same amount and the same polarity as the charged charge measured by the measuring unit to a region of the sheet separated from the conveying member.

  In the present invention configured as described above, when the sheet is a low dielectric sheet having a possibility of generating static electricity when the sheet is conveyed while being sandwiched between the conveying members, the sheet and the conveying member are mutually connected. In the separated regions, the surfaces of the sheet and the conveying member that are in contact with each other are charged with opposite polarities. Since the amount of the charged charge is the same for the sheet and the conveying member, if the measuring unit measures the amount of charged charge in the region separated from the sheet of the conveying member, the charged charge in the region separated from the sheet conveying member is measured. The amount can be grasped. Since the sheet and the conveying member are charged in opposite polarities, the charge imparting means has the same charge as the measured charge amount by the same amount as the charge measured by the conveying member. When applied to a region separated from the sheet conveying member, the charge charged on the sheet and the applied charge are electrically neutralized, and the sheet is neutralized.

  As described above, in the present invention, in the state where the sheet is sandwiched and conveyed by the conveying member, the amount of charged charge in the region separated from the sheet of the conveying member is measured, and the same amount as the measured amount of charged charge In addition, since the charge having the same polarity as that of the charge is applied to the region separated from the sheet conveying member, the sheet charged by being sandwiched between the conveying members is surely discharged without degrading the processing efficiency. be able to. Further, since the charged charge amount of the conveying member is measured, it is not necessary to accurately measure the charged charge amount of the charged sheet, thereby saving space.

  Below, the manufacturing method of the non-contact type IC label 100 shown in FIG. 1 in the IC label manufacturing apparatus comprised as mentioned above is demonstrated.

  When the release paper 120, 150a and the adhesive layer 140b are pulled out from the roller 10a around which the continuous low dielectric sheet having the release paper 120, 150a attached to both surfaces of the adhesive layer 140b is wound, first, the roller 10a The release papers 120 and 150a and the pressure-sensitive adhesive layer 140b drawn out from are peeled off by the roller 10b into the release paper 120 and the pressure-sensitive adhesive layer 140b and the release paper 150a. Here, the release paper 120 and the adhesive layer 140b out of the release paper 120 and 150a and the adhesive layer 140b drawn from the roller 10a are pulled in a predetermined direction by the rotation of the rollers 10h and 10i.

  The release paper 150a peeled from the release paper 120 and the adhesive layer 140b by the roller 10b is then wound around the roller 10c and collected.

  On the other hand, the pressure-sensitive adhesive layer 140b and the release paper 120 from which the release paper 150a has been peeled off by the roller 10b are then conveyed to a region facing the inlet mounting machine 20 by the rotation of the rollers 10h and 10i. Then, the inlet 110 is supplied from the inlet mounting machine 20, and the inlet 110 is mounted on the release paper 120 and the adhesive layer 140b of the adhesive layer 140b.

  The release paper 120 on which the inlet 110 is mounted and the adhesive layer 140b are conveyed to a region sandwiched between the rollers 10h and 10i.

  Further, from the roller 10d around which tack paper, which is a low dielectric sheet in which the release paper 150b is detachably stuck by the adhesive 140a formed on one surface of the surface sheet 130 in a continuous form, is wound on the surface When the sheet 130, the pressure-sensitive adhesive layer 140a, and the release paper 150b are pulled out, the surface sheet 130, the pressure-sensitive adhesive layer 140a, and the release paper 150b drawn from the roller 10d are separated from the surface sheet 130 and the pressure-sensitive adhesive layer 140a by the roller 10e. Peeled to paper 150b. Here, the surface sheet 130 and the adhesive layer 140a out of the surface sheet 130, the adhesive layer 140a and the release paper 150b drawn out from the roller 10d are pulled in a predetermined direction by the rotation of the rollers 10h and 10i, On the other hand, the release paper 150b is pulled in the direction of being wound around the roller 10f, whereby the surface sheet 130, the adhesive layer 140a and the release paper 150b drawn out from the roller 10d are transferred to the surface sheet 130 by the roller 10e. And the adhesive layer 140a and the release paper 150b are peeled off and conveyed in different directions.

  The release paper 150b peeled from the top sheet 130 and the adhesive layer 140a by the roller 10e is then wound around the roller 10f and collected.

  On the other hand, the pressure-sensitive adhesive layer 140a and the surface sheet 130 from which the release paper 150b has been peeled off by the roller 10e are then transported by the roller 10g and are transported to a region sandwiched by the rollers 10h and 10i.

  The release sheet 120 and the pressure-sensitive adhesive layer 140b on which the inlet 110 is mounted, and the surface sheet 130 and the pressure-sensitive adhesive layer 140a, which are drawn from the roller 10d and peeled off by the roller 10e, are separated by the rollers 10h and 10i. The top sheet 130 and the release paper 120 are overlapped so as to sandwich the inlet 110 and the adhesive layers 140a and 140b, and are transported while being sandwiched between the rollers 10h and 10i. The top sheet 130 and the release paper 120 are adhesive. Affixed by layers 140a, 140b.

  When the top sheet 130, the adhesive layers 140a and 140b, and the release paper 120 are transported while being sandwiched between the rollers 10h and 10i, the top sheet 130, the release paper 120, and the rollers 10h and 10i are transported while being sandwiched. The surfaces that were in contact with each other are charged to opposite polarities.

  4A and 4B are diagrams for explaining the static elimination process in the static eliminator 30a shown in FIGS. 2 and 3, wherein FIG. 4A shows the top sheet 130, the adhesive layers 140a and 140b, and the release paper 120 with the rollers 10h and 10i. The figure which shows the charging state of the surface sheet 130 in the state conveyed while being pinched | interposed between, (b) is a figure for demonstrating the state which neutralized the surface of the surface sheet 130 in the static elimination apparatus 30a.

  When the top sheet 130, the adhesive layers 140a and 140b, and the release paper 120 are conveyed while being sandwiched between the rollers 10h and 10i, as shown in FIG. The negative charge is charged on the surface of the roller 10h that is in contact with the roller 10h, and the positive charge is charged on the region of the roller 10h that is in contact with the top sheet 130. In addition, since the topsheet 130 and the roller 10h are not charged before the sandwiching, the negative charge amount charged on the topsheet 130 is equal to the positive charge amount charged on the roller 10h. It becomes.

  Then, at the measurement terminal 31a of the static eliminator 30a, the charged charge amount in the region separated from the top sheet 130 of the roller 10h, that is, the positive charge amount is measured.

  The measurement result at the measurement terminal 31a is given to the ionizer 32a. In the ionizer 32a, positive ions having the same amount as the charge amount measured at the measurement terminal 31a and the same polarity as the charge are generated, and the surface sheet. As shown in FIG. 4B, air is blown to 130, and the generated positive ions are applied to a region separated from the roller 10 h of the top sheet 130.

  Then, as described above, since the negative charge amount charged on the top sheet 130 is equal to the positive charge amount charged on the roller 10h, the top sheet 130 is charged on the top sheet 130. Thus, the same amount of positive charge as that of the negative charge is applied, so that the negative charge charged on the topsheet 130 and the positive charge applied to the topsheet 130 by the ionizer 32a are electrically connected. Neutralizing and the surface sheet 130 is neutralized.

  Here, the positive charge charged in the roller 10h is gradually discharged with the rotation of the roller 10h, but the static eliminator is located downstream in the rotation direction of the roller 10h with respect to the charged charge amount measurement region at the measurement terminal 31a. A region where the surface of the roller 10h is neutralized by applying a negative charge to the surface of the roller 10h by the same amount as both the charged charges measured at the measurement terminal 31a, and the positive charge of the roller 10h is charged. Is in a state of not being charged at all when it comes into contact with the top sheet 130 again. Accordingly, the charged positive charge amount is not accumulated in the region, and when the charged charge amount is next measured at the measurement terminal 31a, the adhesive layers 140a and 140b and the release paper 120 roller It is possible to measure the amount of charged charges by only the carrying process while being sandwiched immediately before 10h and 10i.

  5A and 5B are diagrams for explaining the static elimination process in the static eliminator 30b shown in FIGS. 2 and 3, wherein FIG. 5A shows the top sheet 130, the adhesive layers 140a and 140b, and the release paper 120 with the rollers 10h and 10i. The figure which shows the charging state of the release paper 120 in the state conveyed while being pinched | interposed between, (b) is a figure for demonstrating the state which neutralized the surface of the release paper 120 in the static elimination apparatus 30b.

  When the top sheet 130, the pressure-sensitive adhesive layers 140a and 140b, and the release paper 120 are conveyed while being sandwiched between the rollers 10h and 10i, as shown in FIG. The negative charge is charged on the surface of the roller 10i that is in contact with the roller 10i, and the positive charge is charged in the region of the roller 10i that is in contact with the release paper 120. In addition, since the release paper 120 and the roller 10i are not charged in a state before being sandwiched, the negative charge amount charged on the release paper 120 is equal to the positive charge amount charged on the roller 10i. It becomes.

  Then, at the measurement terminal 31b of the static eliminator 30b, the charge amount in the region separated from the release paper 120 of the roller 10i, that is, the positive charge amount is measured.

  The measurement result at the measurement terminal 31b is given to the ionizer 32b. In the ionizer 32b, positive ions that are the same amount as the charge amount measured at the measurement terminal 31b and have the same polarity as the charge are generated, and the release paper. Air is blown to 120, and thereby, the generated positive ions are applied to a region separated from the roller 10 i of the release paper 120 as shown in FIG.

  Then, as described above, since the negative charge amount charged on the release paper 120 and the positive charge amount charged on the roller 10i are equal, the release paper 120 is charged on the release paper 120. Thus, the same amount of positive charge as that of the negative charge is applied, so that the negative charge charged on the release paper 120 and the positive charge applied to the release paper 120 by the ionizer 32b are electrically connected. The release paper 120 is neutralized by neutralization.

  Here, the positive charge charged on the roller 10i is gradually discharged with the rotation of the roller 10i, but the static eliminator is located downstream of the rotation direction of the roller 10i with respect to the measurement region of the charged charge amount at the measurement terminal 31b. A region where the surface of the roller 10i is neutralized by applying to the surface of the roller 10i a negative charge of the same amount as both of the charged charges measured at the measurement terminal 31b by 50b, and the positive charge of the roller 10i is charged. Is in a state of not being charged at all when it comes into contact with the release paper 120 again. Accordingly, the charged positive charge amount is not accumulated in the region, and when the charged charge amount is next measured at the measurement terminal 31b, the adhesive layers 140a and 140b and the release paper 120 roller It is possible to measure the amount of charged charges by only the carrying process while being sandwiched immediately before 10h and 10i.

  Since the surface sheet 130 and the release paper 120 are neutralized by the charge removal process as described above, static electricity is not generated, and as a result, the sheet composed of the surface sheet 130 and the pressure-sensitive adhesive layer 140a, the release paper 120, and the pressure-sensitive adhesive layer. It is possible to prevent the IC chip 111 of the inlet 110 sandwiched between the sheet made of 140b from being destroyed, and it is difficult for dust or the like to adhere to the surface.

  Thereafter, in the cutting machine 40, only the top sheet 130 and the adhesive layers 140a and 140b of the continuous top sheet 130, the adhesive layers 140a and 140b and the release paper 120 overlapped by the rollers 10h and 10i are flat blades. Or cut into single pieces by a die-cut cylinder. It is also possible to cut all of the top sheet 130, the adhesive layers 140a and 140b, and the release paper 120 into a single piece.

  Thereby, the non-contact type IC label 100 shown in FIG. 1 is manufactured.

  In the present embodiment, it has been described that the rollers 10h and 10i are charged with a positive charge and the topsheet 130 and the release paper 120 are charged with a negative charge. However, the polarity of the charge is limited to this case. In some cases, the rollers 10h and 10i are negatively charged, and the top sheet 130 and the release paper 120 are positively charged.

  Further, as described above, since the charges charged in the rollers 10h and 10i are gradually discharged along with the rotation of the rollers 10h and 10i, the static eliminators 50a and 50b are not necessarily provided.

  Further, in this embodiment, the surface sheet 130 and the release paper 120 that are the front and back of the non-contact type IC label 100 are respectively neutralized, but only the surface of the surface sheet 130 and the release paper 120 that is desired to be neutralized is subjected to the above-described neutralization process. It is also possible to remove static electricity.

  In this embodiment, the example in which the static eliminator of the present invention is used in an IC label manufacturing apparatus that manufactures a non-contact type IC label has been described, but includes a process in which a sheet is sandwiched and conveyed. If there is, the static eliminator of the present invention can be applied as described above.
