Description

  The present invention relates to a method of manufacturing a paper-making paper in which an RFID chip is made, a paper-making paper manufacturing apparatus, and a unit mounting body for paper-making.

Conventionally, RFID (Radio Frequency Identification) tags have been used in order to identify and manage individual products in product manufacturing processes, distribution processes, and the like. There was a paper-made one as shown in Document 1.
Such a paper RFID tag is one in which an RFID film 2 having an RFID chip 1 as shown in FIG. 10 is formed on paper.
The RFID chip 1 is a chip having a communication function, and includes an IC chip 3 and an antenna 4 as shown in FIG. The IC chip 3 is stored with a tag ID and the like, and is read from the outside. Conversely, data is written to the IC chip 3 from the outside.

  The RFID film 2 is obtained by forming an IC chip 3 and an antenna 4 on a base 5 made of a resin film. Specifically, the antenna 4 is formed of copper, aluminum, gold, or the like on a base 5 such as polyethylene terephthalate or glass epoxy by vapor deposition, etching technique, printing, or the like. Further, the IC chip 3 is mounted on the antenna 4 of the base 5. In addition, a resin layer may be formed to protect the IC chip 3 and the antenna 4.

Then, the paper RFID tag as described above is dried after the belt-like film 2 ′ in which a plurality of the RFID chips 1 are continuously provided is sandwiched between a pair of paper layers, and then dried. It was manufactured by cutting according to the shape at the time of use. The strip film 2 ′ is a continuous film of the RFID film 2 embedded in the RFID tag.
At the time of the cutting, the belt-like film 2 ′ is cut together with the paper layer forming the outer layer. For example, when cutting at a cutting position 6 indicated by a two-dot chain line in FIG. 10, an RFID film 2 provided with one RFID chip 1 is made into a paper-made RFID tag.
In the figure, reference numeral m1 is a mark for detecting the cut position 6. For example, the mark m1 can be optically detected from the surface of the paper-making paper, and the cutter can be controlled according to the detection position to cut the belt-like paper-making paper in units of tags.
JP 2005-222299 A

As described above, conventionally, when manufacturing a paper-made RFID tag, the strip-like film 2 ′ has been cut in, and the cut-in paper has been cut in accordance with the usage form of the tag.
At the time of cutting the engraved paper, the strip-shaped film 2 ′ is also cut at the same time. Therefore, the cut position must be between the RFID chip 1 and the RFID chip 1 as the cut position 6 in FIG. 10. In other words, the cutting position of the paper-making paper is determined by the interval between the RFID chips 1 in the belt-like film 2 ′. Since the cut position 6 can be changed only within the range between the adjacent RFID chips 1 in the belt-like film 2 ′, for example, one RFID chip 1 is provided, and a portion other than the chip is enlarged around the RFID chip 1. If the tag is to be manufactured, the adjacent RFID chip 1 will be damaged.

In addition, even when a plurality of RFID chips 1 are arranged in one paper tag, the arrangement depends on the arrangement of the RFID chips 1 in the strip film 2 ′.
In other words, when manufacturing paper with various arrangements of the RFID chip 1 is manufactured, it is necessary to prepare a belt-like film 2 ′ having the RFID chip 1 arranged accordingly.
Thus, in order to change the arrangement of the RFID chip 1 in the belt-like film 2 ′, it must be changed from the manufacturing process of the belt-like film 2 ′, and as a result, the paper made by embedding the RFID chip. There was a problem that the manufacturing cost of the would increase.
The subject of this invention is providing the manufacturing method and manufacturing apparatus of the papermaking paper which can set the position of an RFID chip arbitrarily.

  The first invention is characterized in that, while a unit mounting body composed of RFID chip units is formed on paper, a supply timing of the unit mounting body and a transport speed of the paper are arbitrarily adjusted.

  An RFID chip papermaking apparatus according to a second aspect of the present invention is an RFID chip papermaking machine that mounts an RFID chip and manufactures a papermaking paper in which a unit mounting body formed for each RFID chip is made on paper. A paper making apparatus, comprising: a first paper making means for forming a first paper layer; a second paper making means for forming a second paper layer; and the unit mounting body provided between the first and second paper layers.

  A third aspect of the invention is an RFID chip-embedded paper manufacturing apparatus that mounts an RFID chip and manufactures a paper sheet in which a unit mounting body formed in units of RFID chips is formed on paper. A first paper making means for forming a paper layer; a second paper making means for forming a second paper layer; a paper layer conveying means for conveying the first and second paper layers; A unit mounting body supplying means for supplying a unit mounting body, and the unit mounting body supplying means includes a porous transport roller opposed to the second paper layer with a gap therebetween, and a porous transport roller in the porous transport roller. A negative pressure generating means that can rotate relative to the perforated transport roller and maintain a predetermined position, and the surface of the perforated transport roller is adsorbed by the suction area corresponding to the suction means and the unit mounting body. In addition to the non-adsorption area other than the area, It is configured to be sucked by the suction area of the transport roller and transported in the direction of the second paper layer, and the front end of the unit mounting body in the transport direction faces the non-suck area and peels off from the porous transport roller to be second. In a state where it is in contact with the paper layer, at least the rear end in the transport direction of the unit mounting body is in the suction area and is sucked by the transport roller, and then the mounting body is placed on the second paper layer. It is characterized in that it is configured as described above.

  4th invention presupposes the said 3rd invention, it exists in the said porous conveyance roller, Comprising: It corresponds to the said non-attraction | suction area, and a positive pressure generation | occurrence | production means in the relative position adjacent to the attraction | suction area ahead of a conveyance direction This positive pressure generating means is characterized in that it is configured to be rotatable relative to the perforated transport roller and to hold a predetermined position.

  The fifth invention is characterized in that the relative position between the perforated conveyance roller and the boundary between the suction area and the non-suction area can be adjusted based on the third or fourth invention.

  6th invention presupposes the said 4th or 5th invention, maintaining the relative position of the said negative pressure generation means and a positive pressure generation means, the said negative pressure generation means and a positive pressure generation with respect to a porous conveyance roller It is characterized in that the means can be rotated.

  7th invention presupposes 3rd-6th invention, provided the rotation support member in the both ends of the rotating shaft which supports a porous conveyance roller and a negative pressure generation means rotatably, This rotation support member is This is characterized in that it is supported via a support shaft that is eccentric with respect to the rotation shaft, and that the perforated transport roller can be swung as the support shaft rotates.

  According to an eighth aspect of the present invention, the unit mounting body for papermaking in the first to seventh aspects mounts the RFID chip on the base, and the base includes a slit, a perforation or a continuous small hole. It is characterized by having a cut for dehydration.

  According to the first to eighth inventions, it is possible to easily and inexpensively manufacture a paper sheet in which the position of the RFID chip is arbitrarily set regardless of the arrangement of the RFID chip on the belt-like film.

  According to the third to seventh inventions, the unit mounting body floats in the air since at least the rear end is held by the perforated transport roller while the front end of the unit mounting body is in contact with the second paper layer. It will not be in the state. Therefore, the orientation of the unit mounting body does not change, and the position of the RFID chip in the paper can be accurately controlled.

  In particular, in the fourth aspect of the invention, since the positive pressure generating means is provided at a relative position corresponding to the non-adsorption area and adjacent to the suction area in the front in the transport direction, the pressure from the positive pressure generation means The unit mounting body sucked in the suction area can be easily separated, and the part away from the roller can be pressed against the second paper layer. Thereby, a unit mounting body can be mounted more rapidly on the 2nd paper layer.

  According to the fifth to seventh aspects, the position of the boundary between the adsorption area and the non-adsorption area of the porous conveyance roller with respect to the second paper surface on which the unit mounting body is placed can be adjusted. It is possible to control the discharge timing of the unit mounting body held in step 1 and select the optimum conditions for more accurate alignment.

Since the unit mounting body of the eighth invention is provided with the dewatering cut, the moisture contained in the paper layer in the wet paper state can be quickly dehydrated by using this unit mounting body. Therefore, there is almost no fear that the paper layer is destroyed by the moisture contained therein, and any size RFID chip can be included in the paper layer. Moreover, the drying load for removing moisture can be reduced, and energy saving can also be realized.
In particular, it is more effective when the base of the unit mounting body is made of a non-permeable member such as a resin film.

A first embodiment of the present invention will be described with reference to FIGS.
FIG. 1 and FIG. 2 are diagrams showing a papermaking machine for producing a strip-shaped paper 7 in which the RFID chip 1 (see FIG. 3) is made.
The papermaking means in the present invention is a general papermaking machine for making paper and paperboard, such as a circular net, a long net, or an inclination classified according to the shape of the net for papermaking such as pulp. The present invention can be implemented using wires. By combining a plurality of circular nets, a plurality of long nets, or a circular net or a long net, laminated paper or paperboard can be produced. FIG. 1 shows an example of a paper machine for producing RFID chip paper for use in the present invention, but the paper making means is not limited to this, and a general method used for paper making can be used.

FIG. 1 shows a production line for paper making from the paper making process at the right end until the belt-like paper 7 in which a plurality of RFID chips 1 are continuously made is wound around the roller 8 at the left end in the figure. FIG. 2 is a diagram showing a configuration of a unit mounting body supply device 27 that supplies the unit mounting body 9 including the RFID chip 1 in the production line shown in FIG.
The unit mounting body 9 is obtained by cutting the band-like film 9 ′ shown in FIG. 3 in units of RFID chips, and includes an RFID chip 1 including an IC chip 3 and an antenna 4 on a base 5. The RFID chip 1 is the same as that of the conventional example shown in FIG. 10, and the strip film 9 ′ can be manufactured in the same manner as the strip film 2 ′ of the conventional example shown in FIG. Therefore, also in FIG. 3, the same reference numerals as those in FIG. 10 are used for the same configuration as that of the strip-shaped film 2 ′.

However, the base 5 of the strip-shaped film 9 ′ of the first embodiment is different from the conventional example in that a plurality of dewatering cuts 10 are formed for each unit mounting body 9.
Further, the base of the RFID unit mounting body in the present invention is not limited to a resin film. For example, a unit mounting body may be formed by cutting a paper-like band-like body in which the base is made of paper and the RFID chip 1 is mounted by a printing technique in units of RFID chips.

Next, the manufacturing line shown in FIG. 1 will be described in the order of steps from the right side of the drawing.
First, as a first paper making means for forming the first paper layer a of the present invention, a pulp slurry tank 11, a roller-shaped circular mesh 12 formed of a metal mesh, a belt 13 and a support roller 14 are provided. The belt 13 indicated by the wavy line is made of felt, and when the circular mesh 12 is rotated in the direction of the arrow in the drawing to scoop up the pulp slurry having a pulp concentration of 1 to 40% from the pulp slurry tank 11 and press it against the belt 13, The wet pulp is attached to the belt 13 so that the first paper layer a can be made.
Also, rollers 15 and 16 are provided along the conveyance direction of the first paper layer a indicated by the arrow A in FIG. 1, and the belt 13 is stretched over these rollers and other support rollers (not shown), A motor is linked to this roller, and the first paper layer a is conveyed to a drying step 25 described later.

  On the other hand, as the second paper making means for forming the second paper layer b of the present invention, the rollers 18, 19, 20 are stretched over them, the mesh belt 21 indicated by a broken line, and the mesh belt 21 indicated by the arrow B on the mesh belt 21. Thus, a pulp slurry supply device (not shown) for supplying a pulp slurry having a pulp concentration of 0.05 to 5% is provided. When the pulp slurry is supplied to the mesh belt 21, moisture is discharged through the mesh belt 21, and wet pulp adheres to the surface of the mesh belt 21 to form the second paper layer b. Then, the second paper layer b on the mesh belt 21 is conveyed in the direction of arrow C by rotating the motor linked to one of the rollers around which the mesh belt 21 is wound.

  Further, the roller 16 supporting the felt belt 13 and the roller 18 supporting the mesh belt 21 are brought close to each other so that the second paper layer b formed on the mesh belt 21 is pressed against the first paper layer a. . Thereby, the second paper layer b is conveyed by the belt 13 integrally with the first paper layer a. That is, in the first embodiment, the belt 13 constitutes the paper layer conveying means of the present invention. It is controlled so that the moving speed of the belt 13 and the mesh belt 21 of the second paper making means coincide.

  Further, the unit mounting body 9 is supplied between the first paper layer a and the second paper layer b at a position before the integration with the first paper layer a in the transport process of the second paper layer b. A unit mounting body supply device which is a unit mounting body supply means is provided. The unit mounting body supply device 27 will be described in detail later, but the unit mounting body 9 is discharged from the discharge section 28 of the device 27 onto the second paper layer b. The unit mounting body 9 is conveyed by the second paper layer b, covered by the first paper layer a between the roller 16 and the roller 18, and sandwiched between the first paper layer a and the second paper layer b. In this state, it is conveyed in the left direction in the figure.

In front of the conveying direction, a pair of squeezing rollers 17 and 22 and a roller 24 that spans the felt belt 23 between the rollers 22 are provided. Further, a drying step 25 is provided at the tip.
Further, immediately after the drying step 25, a paper layer speed sensor S1 for detecting the transport speed of the paper layer is provided, and the paper layer speed sensor S1 is connected to a controller 29 described later.
The paper layer speed sensor S1 may be provided anywhere in the paper layer conveyance process, but the paper layer expands and contracts when the paper layer contains a large amount of moisture, and the detected paper layer is conveyed. Since the speed may vary, the speed is provided on the outlet side of the drying step 25 here.

The squeezing rollers 17 and 22 are provided so as to lightly press the paper layer in order to squeeze moisture from the paper layer passing between them to the felt belt 23. However, this pressing force is set to a pressure that does not damage the RFID chip 1 provided between the paper layers.
When the paper layer from which water has been squeezed by the squeezing rollers 17 and 22 and the felt belt 23 as described above passes through the drying step 25 and is dried, the paper is made as the paper 7 into which the unit mounting body 9 is made. 26 is configured to be wound around the take-up roller 8.

In the first embodiment, the water content of the first paper layer a and the second paper layer b before entering the drying step 25 is about 50 to 90%, but after the drying step 25, the water content is 5 to 10%. The paper 7 is completed. As shown in FIGS. 4 and 5, the completed paper 7 is a paper in which the unit mounting bodies 9 are papered at a predetermined interval. In the cross-sectional view shown in FIG. 5, the paper layers a and b are shown. However, in the completed paper 7, these two paper layers are integrated and separated into layers at portions other than the unit mounting body 9. There is no.
The drying step 25 may be provided with any mechanism as long as the paper layer can be dried. For example, it is possible to use a cylinder dryer that makes a paper layer come into contact with the heated surface and dry it, or a blower that blows dry hot air on the paper layer conveyance line.

  Further, as shown in FIG. 3, a dewatering notch 10 is formed on the unit mounting body 9 cut into the space between the first paper layer a and the second paper layer b of the first embodiment. Since the body 9 is configured to allow moisture to pass, the following effects can be obtained. Usually, a plastic film is often used as the base material of the unit mounting body 9, and in this case, there is no movement of moisture between the front and back of the film. Therefore, when a pressure is applied by the squeezing rollers 17 and 22, the paper layer containing moisture is destroyed, and it may be difficult to enclose the RFID chip 1 in the paper layer. This tends to become more prominent as the base of the RFID chip 1 is larger. However, when the dewatering notch 10 is formed as in the first embodiment, the dewatering notch 10 is not provided. In contrast, when lightly pressed by the squeezing rollers 17 and 22, moisture contained in the paper layer can be dehydrated more quickly without destroying the paper layer. Therefore, a unit mounting body of any size can be included in the paper layer.

Moreover, if dehydration can be performed quickly as described above, the load of the drying step 25 can be reduced.
In addition, even when the base of the unit mounting body 9 is not made of resin and is made of paper, there is an advantage that the dehydration can be easily performed by providing the dewatering cut 10.
Further, the dewatering notch 10 has a slit shape, but may be a perforation or a small hole. As long as moisture can be discharged, the opening shape and the opening size of the dewatering cut may be any. However, in terms of manufacturing, a shape such as a slit or a small hole that does not generate a chip when a cut is formed is preferable.

Next, the unit mounting body supply device 27 for supplying the unit mounting body 9 to the papermaking sheet 7 at an arbitrary interval will be described.
As shown in FIG. 2, the unit mounting body supply device 27 is configured by attaching various components to a support member 30, and discharges the strip film 9 ′ on which the RFID chip 1 is mounted as a unit mounting body 9 from the discharge unit 28. Device. Although not shown here, the transport line for the second paper layer b described above is provided below the discharge unit 28 so that the unit mounting body 9 is supplied onto the second paper layer b. I have to.

  In the unit mounting body supply device 27, a supply roller 31 around which the strip film 9 ′ is wound is provided at the starting point of the transport line of the strip film 9 ′ and the unit mounting body 9, and the supply motor 31 includes a torque motor M1. Is connected. When the belt-like film 9 ′ is drawn out from the supply roller 31, the torque motor M <b> 1 applies a torque in a direction that serves as a rotation resistance to the supply roller 31.

Further, a driving roller 32 and a pressing roller 33 for feeding the strip-shaped film 9 ′ from the supply roller 31 toward the discharge portion 28 of the unit mounting body 9, and a driving roller for controlling the feeding amount of the strip-shaped film 9 ′. 34, a pressing roller 35, and upper and lower conveying belts 36 and 37 are provided. A feed motor M2 is connected to the drive roller 32, and a stepping motor M3 capable of accurately controlling the feed amount of the belt-like film is connected to the drive roller 34.
Further, a cutter 38 is provided immediately before the upper and lower conveying belts 36, 37, and a cutter mechanism M4 for driving the link mechanism 39 and a link mechanism 39 for moving the cutter mechanism 38 are provided on the upper blade 38a of the cutter 38. .

The upper conveyor belt 36 is stretched over a plurality of guide rollers 40, 41, 42, 44 and a driving roller 43, and the driving roller 43 is connected to a conveyor motor M5 to drive the upper conveyor belt 36. Yes.
The lower conveyor belt 37 is also stretched over a plurality of guide rollers 45, 46, 47, 49 and a drive roller 48, and a conveyance motor M 5 is connected to the drive roller 48. 37 is driven.
The belt-shaped film 9 ′ or the unit mounting body 9 is sandwiched between the opposed surfaces of the upper and lower conveyor belts 36 and 37, and is conveyed.

Further, a sag sensor S2 for detecting a sag state of the belt-like film 9 'is provided between the drive roller 32 and the drive roller 34, and the sag sensor S2 is connected to the feed motor M2. The feed motor M2 is operated according to the output of the sag sensor S2.
The sag sensor S2 outputs a signal depending on whether or not a predetermined amount of sag is detected, and the feed motor M2 is operated based on the signal, and the drive roller 32 and the drive roller 34 are always substantially constant. I try to make slack. In other words, until the sag sensor S2 detects a predetermined amount of sag, the feed motor M2 is driven to feed out the belt-like film 9 ′ so that the belt-like film 9 ′ is slackened.

Further, a mark sensor S3 for detecting a mark m1 provided on the belt-like film 9 ′ is provided between the drive roller 34 and the cutter 38. The mark sensor S3 is connected to the controller 29, and a detection signal of the mark sensor S3 is output to the controller 29.
Further, the controller 29 is connected to motors M3, M4, M5 provided in the unit mounting body supply device 27, and the controller 29 controls each motor.

The operation of this device for supplying the unit mounting body 9 by this device will be described below.
First, the belt-like film 9 ′ fed out from the supply roller 31 is stretched over each roller as shown in FIG. 2, and the leading end thereof is supported between the guide rollers 40 and 45 of the upper and lower conveying belts 36 and 37, and the apparatus 27. Start.

  When the unit mounting body supply device 27 is started and the sag sensor S2 functions, the sag sensor S2 detects a sag state between the drive rollers 32 and 34. Here, when the sag sensor S2 does not detect a sag exceeding a predetermined amount set in advance, a signal is output to the feed motor M2, the feed motor M2 is driven, and the belt-like film 9 is driven from the supply roller 31. Pull 'and let it go out. At this time, the torque motor M1 connected to the supply roller 31 applies a rotational torque to the supply roller 31, thereby applying an appropriate tension between the supply roller 31 and the drive roller 32 to the fed film 9 '. In addition, the band-like film 9 ′ does not flutter, and operates stably.

When the belt-like film 9 ′ is drawn out by the feed motor M2, the belt-like film 9 ′ sags, so that the sag sensor S2 detects it and stops the feed motor M2.
On the other hand, the controller 29 controls the amount of rotation of the stepping motor M3 based on the mark detection signal from the mark sensor S3, feeds the strip film 9 ′, and cuts the strip film 9 ′ to the cut position of the cutter 38. 6 (see FIG. 3) coincide with each other and stop.

  In the first embodiment, while maintaining the state in which the strip film 9 ′ is slackened by the feed motor M2, the stepping motor M3 is driven to accurately feed the strip film 9 ′. This is to prevent the amount of feeding from the supply roller 31 from being less than the amount desired to be fed by the stepping motor M3 and excessive tension from acting on the film. If the belt-like film 9 ′ is pulled toward the supply roller 31, there is a concern that the feed amount cannot be accurately controlled by the stepping motor M <b> 3. However, if the feeding from the supply roller 31 and the feeding of the stepping motor M3 can be matched, it is not always necessary to sag the belt-like film 9 '.

As described above, when the cutting position 6 of the belt-like film 9 ′ coincides with the cutting position of the cutter 38, the controller 29 drives the cutting motor M4 to cut the belt-like film 9 ′ with the upper blade 38a, thereby unit mounting body. 9 is generated. The cutter 38 has a structure in which the upper blade 38a is lowered to cut the belt-like film 9 '. However, in order to cut the belt-like film 9', any cutter such as a laser cutter is used. Also good.
The unit mounting body 9 generated in this way is sandwiched between the upper and lower conveying belts 36 and 37 and is conveyed by driving the conveying motor M5. From the end of the upper and lower conveying belts 36 and 37, the discharge unit 28 is provided. And is discharged onto the second paper layer b.

The controller 29 controls the transport speed of the unit mounting body 9 by controlling the transport motor M5 based on the detection signal from the paper layer speed sensor S1 (see FIG. 1). That is, the supply timing between the paper layers a and b can be controlled. The arrangement of the unit mounting bodies 9 in the papermaking sheet 7 can be adjusted by the supply timing of the unit mounting bodies 9 to the paper layer.
For example, the supply speed of the unit mounting body 9 is slower with respect to the paper layer conveyance speed, and the larger the difference, the larger the interval between the unit mounting bodies 9 woven into the paper sheet 7. When the difference is small, the interval between the unit mounting bodies 9 is narrowed. The transport motor M5 is the unit mounting body transport motor of the present invention.

Thus, if the controller 29 controls the transport motor M5 based on the signal from the paper layer speed sensor S1, the unit mounting body 9 can be supplied at an arbitrary timing, and as a result, the unit mounting body. The papermaking paper 7 which arrange | positions 9 in arbitrary intervals can be manufactured. That is, it is possible to manufacture the papermaking paper 7 in which the interval between the RFID chips 1 is arbitrarily adjusted.
On the other hand, in the conventional method, when it is desired to engrave with a large gap between the RFID chips 1, the gap between the RFID chips 1 must be large in the state of the strip film 2 ′. However, if the method and apparatus of the present invention are used, it is possible to manufacture a wide-interval film using the same belt-shaped film as that used when the RFID chip unit mounting body is engraved at a narrow distance. become.

Therefore, even when the paper-like tag 7 is formed by cutting the strip-shaped paper 7 in which a plurality of RFID chips 1 are continuously formed, the RFID chip 1 can be easily arranged arbitrarily. It becomes like this.
In the first embodiment, the unit mounting body supply device 27 that is a unit mounting body supply means has a function of generating the unit mounting body 9 by cutting the strip film 9 ′. The supply means does not have a cutting function, but has only a function of supplying a unit mounting body 9 cut by another device or a unit mounting body formed in advance in units of the RFID chip 1 according to the paper layer conveyance speed. It does not matter if it is

FIG. 6 is a diagram showing the papermaking apparatus of the second embodiment. This papermaking apparatus is also similar to the first embodiment shown in FIG. A unit mounting body 9 (see FIG. 3) on which the RFID chip 1 is mounted is sandwiched between the two paper layers b, and the paper 7 is manufactured. The apparatus of the second embodiment includes a unit mounting body discharge device 27 ′ that discharges the unit mounting bodies 9 one by one, and a first roller is provided between the discharge port 28 and the second paper layer b. Unit mounting body supply means 50 including 51 and the second roller 52 is provided.
The unit mounting body discharge device 27 ′ is a device for discharging the unit mounting body 9 supplied onto the second paper layer b at a predetermined timing. The unit mounting body supply of the first embodiment shown in FIG. This is the same device as the device 27.

Moreover, this 2nd Embodiment is the same structure as the said 1st Embodiment except having provided the said unit mounting body supply means 50. FIG. That is, the paper making apparatus of the first embodiment receives the unit mounting body 9 discharged from the discharge port 28 of the unit mounting body supply apparatus 27 directly by the second paper layer b and receives the first paper layer. In contrast, in the apparatus of the second embodiment, the unit mounting body 9 discharged from the unit mounting body discharging apparatus 27 ′ is supplied as a unit mounting body, while the paper is drawn between a and the second paper layer b. The difference is that it is supplied onto the second paper layer b via the means 50.
Therefore, the same reference numerals are used for the same components as those in the first embodiment, and detailed descriptions of the respective components are omitted. Hereinafter, portions different from those in the first embodiment will be described.

  As shown in FIG. 7, the unit mounting body supply means 50 includes a first roller 51 and a second roller 52, and the first roller 51 is provided close to the discharge port 28 of the unit mounting body discharge device 27 ′. The second roller 52 is provided between the first roller 51 and the first paper layer b. Then, the surfaces of the first roller 51 and the second roller 52 are in contact with each other or close to the contact state, and a predetermined distance h is maintained between the second roller 52 and the surface of the second paper layer b. I have to.

Each of the first and second rollers 51 and 52 is a metal cylindrical roller whose surface is water-repellent by silicon coating or the like, and has a large number of pores 55 (see FIG. 9) on its side surface. Through these pores 55 to allow the passage of air inside and outside the roller. Further, each of the first roller 51 and the second roller 52 is composed of a chamber partitioned inside, and a negative pressure generating portion 53 and a positive pressure generating source which are negative pressure generating means of the present invention connected to a negative pressure generating source. And a positive pressure generating portion 54 which is a positive pressure generating means of the present invention connected to the. The negative pressure generating portion 53 and the positive pressure generating portion 54 are adjacent to each other, and the positive pressure generating portion 54 is provided in front of the negative pressure generating portion 53 in the rotation direction of the rollers 51 and 52.
The first roller 51 and the second roller 52 have different positional relationships between the negative pressure generating unit 53 and the positive pressure generating unit 54, but the individual configurations are the same, and the specific configuration will be described later. To do.
The first and second rollers 51 and 52 are perforated transport rollers of the present invention.

Each of the chambers constituting the negative pressure generating portion 53 and the positive pressure generating portion 54 is provided with a plurality of pores 56 (see FIGS. 8 and 9) on the outer peripheral surface thereof. As shown by the broken arrows, the inside and outside of the roller can be ventilated.
As a result, air is sucked from the outside of the roller into the roller corresponding to the negative pressure generating portions 53 and 53 on the surfaces of the rollers 51 and 52, and the unit mounting body 9 is positioned at the position. At this time, the suction areas 51a and 52a of the present invention for sucking it are formed. In FIG. 7, the suction areas 51a and 52a are indicated by alternate long and short dash lines.
On the other hand, portions on the roller surface other than the suction areas 51a and 52a become the non-suction areas 51b and 52b of the present invention. Further, in the non-adsorption areas 51b and 52b of the respective rollers 51 and 52, the portions corresponding to the positive pressure generating portion 54, and the hatched positions in FIG. Are discharged areas 51c and 52c.

Then, one boundary part 51d between the suction area 51a and the non-suction area 51b of the first roller is opposed to the vicinity of the discharge part 28 of the unit mounting body 9, and the other boundary part 51e is set to the suction area 52a of the second roller 52. And the other boundary portion 52e are provided so as to face the surface of the second paper layer b.
Each of the rollers 51 and 52 is supported on a frame (not shown) so as to be rotatable about the axes O1 and O2, and the negative pressure generating portions 53 and 53 and the positive pressure generating portions 54 and 54 are mounted on the frame. It is fixed with respect to it so that it does not rotate.

  Therefore, when the unit mounting body 9 is transported, the first roller 51 is rotated in the direction of arrow D and the second roller 52 is rotated in the direction of arrow E, so that the unit mounting body 9 discharged from the discharge port 28 is Then, the sheet is conveyed toward the second roller 52 while being held in the suction area 51 a of the first roller 51. Then, the tip of the unit mounting body 9 held by the first roller 51 moves away from the first roller 51 when it reaches the discharge area 51 c, and is sucked and held by the suction area 52 a of the second roller 52. To the second roller 52.

When the unit mounting body 9 sucked and held by the second roller 52 is transported in the direction of arrow E and the tip of the unit mounting body 9 enters the discharge area 52c beyond the boundary 52e between the suction area 52a and the non-suction area 52b, The front end side of the unit mounting body 9 is separated from the surface of the second roller 52 and falls toward the second paper layer b. Then, as shown in FIG. 7, at least the unit mounting body is in the state where the tip 9a of the unit mounting body 9 located between the second roller 52 and the second paper layer b is in contact with the surface of the second paper layer b. 9 is attracted and held in the adsorption area 52a.
When the second roller 52 further rotates from this state, the area where the unit mounting body 9 contacts the second paper layer b increases, and the unit mounting body 9 comes into close contact with the second paper layer b in the wet paper state. The rear end is separated from the second roller 52 beyond the boundary 52e, and the unit mounting body 9 is placed on the second paper layer b. In this way, the rear end 9b is held in the suction area 52a from the time when the front end 9a of the unit mounting body 9 comes into contact with the second paper layer b until the contact area increases to some extent. The position of the boundary portion 52e and the interval h are set.

  In the second embodiment, the tip 9a of the unit mounting body 9 is separated from the suction area 52a, away from the second roller 52, and hooked on the discharge area 52c. Not only the suction force does not act on the side, but also the pressure of the air discharged from the positive pressure generating part 54 acts and is pressed onto the second paper layer b. In this way, the unit mounting body 9 is more securely brought into close contact with the second paper layer b by pressing the front end against the second paper layer b until the rear end of the unit mounting body 9 is removed from the suction area 52a. be able to. In addition, when the front end of the unit mounting body 9 is pressed by the air pressure in the discharge area 52c, the rear end 9b is held, so that the unit mounting body 9 is not displaced by the air pressure in the discharge area 52c. Accurate alignment is possible.

For example, as in the first embodiment, the unit mounting body 9 discharged from the discharge unit 28 that is spaced from the surface of the second paper layer b spontaneously falls onto the second paper layer b. In the case of being placed, the unit mounting body 9 has time to float in the air, and during that time, the direction of the unit mounting body 9 changes and landed on the second paper layer b There is also here where the position of. Therefore, in order to shorten the time during which the unit mounting body 9 is floating in the air, the distance between the discharge unit 28 and the surface of the second paper layer b must be shortened. If the contact is made with the surface b, the surface of the paper layer being conveyed will be disturbed and the quality of the paper layer will be adversely affected. Therefore, it is necessary to select the optimum distance in consideration of the size of the unit mounting body 9. There is.
However, a large mechanism is required to adjust the position of the entire unit mounting body supply device 27 by moving it up and down with respect to the transport path of the second paper layer b.

On the other hand, in the apparatus for transporting the unit mounting body 9 so as not to float in the air until it is placed on the second paper layer b as in the second embodiment, the second paper layer b is used. Since it is sufficient to adjust the position of the second roller 52 with respect to the surface of the lens, there is an advantage that the position adjusting mechanism and work are simple.
Further, since the longer the time that the unit mounting body 9 is floating in the air, the longer the moving amount of the second paper layer b on which the unit mounting body 9 is placed, the position variation becomes larger. In the method of placing the unit mounting body 9 that is floated on, the transport speed of the paper layer could not be made very fast, but the state where the rear end 9b of the unit mounting body 9 is held by the roller 52 as in the second embodiment. When the tip 9a is brought into contact with the surface of the second paper layer b, there is no time for the unit mounting body 9 to float in the air. The conveyance speed can be increased.

  In addition, since the first and second paper layers a and b before embedding the unit mounting body 9 are in a wet paper state, the atmosphere including these paper layer transport paths is in a high humidity state. Water also adheres to the surfaces of the two rollers 51 and 52. Therefore, even if the unit mounting body 9 held on the roller surface moves to the non-adsorption areas 51b and 52b and is released from the adsorption force by the negative pressure generating unit 53, the unit mounting body 9 may be in close contact with moisture and hardly peel off from the roller. is there. In the second embodiment, the surface of the first and second rollers 51 and 52 is water-repellent to suppress adhesion of moisture, but the unit mounting body 9 is still difficult to peel off due to moisture. Sometimes. However, if the discharge areas 51c and 52c corresponding to the positive pressure generators 54 and 54 are provided as in this embodiment, the unit mounting body 9 can be forcibly removed from the roller surface.

Next, a specific configuration example of the second roller 52 configuring the unit mounting body supply unit 50 of the second embodiment will be described with reference to FIGS.
FIG. 8 is a perspective view showing the negative pressure generator 53 and the positive pressure generator 54 inside the second roller 52, and FIG. 9 is a cross-sectional view through the negative pressure generator 53 of the second roller 52.
As shown in FIG. 8, the cylindrical second roller 52 includes a cylindrical chamber having a bottom surface concentric with the axis O2 of the second roller 52 and a large number of pores 56 on the outer peripheral surface. The negative pressure generating unit 53 and the positive pressure generating unit 54 are incorporated. An exhaust passage 57a connected to a negative pressure generation source is connected to the negative pressure generation portion 53, and an air supply passage 57b connected to a positive pressure generation source is connected to the positive pressure generation portion 54. The exhaust passage 57 a and the air supply passage 57 b are formed in one cylindrical pipe 57, and the pipe 57 is aligned with the axis O 2 of the second roller 52.

Further, in the negative pressure generating portion 53 and the positive pressure generating portion 54, a disc-shaped support member 58a indicated by a two-dot chain line is fixed to the end opposite to the pipe 57, and the negative pressure generating portion 53 and The positive pressure generating portion 54 is integrated, and a support shaft 58 having an axial center aligned with the axial center O2 is fixed to the center of the support member 58a. That is, the support shaft 58 and the pipe 57 are located on the axis O2.
In FIG. 9, reference numeral 62 denotes a seal member provided on the outer periphery of the negative pressure generating unit 53. The seal member 62 divides a range in which the negative pressure of the negative pressure generating unit 53 acts in the second roller 52. Similarly, a seal member (not shown) is provided between the positive pressure generating portion 54 and the second roller 52.

Then, as shown in FIG. 9, a second roller 52 is rotatably attached to the support shaft 58 and the pipe 57 via a bearing 59, and a motor M is linked to the second roller 52 so that the second roller 52 is rotated.
Further, rotation support members 60 and 60 are fixed to the support shaft 58 and the pipe 57, respectively, and support shafts 61 and 61 eccentric to the rotation axis O2 are attached to the rotation support members 60 and 60, respectively. The support shafts 61 and 61 are attached to the frame via bearings 59. Therefore, the support shaft 58 can be rotated around the support shaft 61, and the second roller 52 can swing around the support shaft 61. In FIG. 7, the axis of the support shaft 61 is represented as a swing center P.

As described above, since the second roller 52 can be swung around the swing center P, the second roller 52 and the second roller 52 can be adjusted according to the size of the unit mounting body, the thickness of the second paper layer b, and the like. The distance h from the surface of the paper layer b and the position of the boundary portion 52e (see FIG. 7) can be adjusted.
8 and 9 show the inside of the second roller 52 and its support mechanism. Although the first roller 51 is not shown, the negative pressure generator 53 and the positive pressure generator 54 are The structure which is formed in the first roller 51 and the first roller 51 is rotatably supported on the outer periphery of these support shafts via bearings is the same as the second roller 52. However, the first roller 51 aligns the axis of the support shaft 58 and the pipe 57 with the axis O1 of the roller, and supports the shaft with the axis O1. For this reason, the first roller 51 does not include the rotation support member 60 and the eccentric support shaft 61.

  In the second embodiment, since the negative pressure generating portion 53 and the positive pressure generating portion 54 are integrated by the support member 58a, the relative positional relationship between them is maintained even if the second roller 52 is swung. ing. Then, by swinging the second roller 52 about the swing center P, not only the interval h but also the boundary 52e between the suction area 52a and the non-suction area 52b, the second paper layer b, The relative position of also changes. The timing at which the rear end 9b of the unit mounting body 9 held by the second roller 52 is separated from the second roller 52 also changes by changing the position of the boundary portion 52e in this way.

  Further, the positions of the negative pressure generating portion 53 and the positive pressure generating portion 54 in the second roller 52 can be changed with respect to the second roller 52, and the boundary portion 52e between the suction area 52a and the non-adsorption area 52b is You may make it adjustable irrespective of the said space | interval h. In this way, the supply timing of the unit mounting body 9 from the second roller 52 onto the second paper layer b can be controlled without swinging the second roller 52. For example, the negative pressure generating portion 53 and the positive pressure generating portion 54 are rotated by providing a pipe 57 and a support shaft 58 so as to be rotatable with respect to the pair of rotation support members 60 and 60 shown in FIG. Thus, the position of the boundary portion 52e can be adjusted.

  In the second embodiment, the unit mounting body supply unit of the present invention is configured by the two perforated transport rollers, the first and second rollers 51 and 52, but the unit mounting body supply unit is configured. The number of perforated conveyance rollers is not limited to this. For example, only one perforated conveyance roller may be provided between the discharge portion 28 of the unit mounting body and the second paper layer b, or three or more perforated rollers may be provided. However, when the number of perforated conveyance rollers is an odd number, the discharge direction of the unit mounting body 9 discharged from the discharge unit 28 is opposite to the supply direction supplied onto the second paper layer b. You may select according to.

Further, the positive pressure generator 54 is not provided in the second roller 52, and pressure is not applied to the unit mounting body 9 in the non-adsorption area 52b other than the adsorption area 52a corresponding to the negative pressure generator 53. It doesn't matter. As described above, in the case where the discharge area 52c corresponding to the positive pressure generation unit 54 is not provided in the non-adsorption area 52b, if only the negative pressure generation unit 53 is movable, the boundary between the adsorption area and the non-adsorption area 52e can be changed.
However, as described above, the atmosphere of the machine for manufacturing paper-making paper provided with the paper-making means is high humidity. Therefore, in order to reliably separate the unit mounting body 9 from the surface of the second roller 52, it is necessary to It is preferable to provide the pressure generating hand portion 54 to form the discharge area 52c.
In addition, when supplying a unit mounting body using a plurality of perforated transport rollers, the perforated transport roller that does not oppose the second paper layer b is also provided with a positive pressure generating part and forms a discharge area. The unit mounting body 9 can be moved from the roller to the perforated conveyance roller more quickly and stably.

  Further, in the second embodiment, the unit mounting body discharge device 27 ′ is used to supply the unit mounting body to the first roller 51 constituting the unit mounting body supply means. The configuration of the device 27 ′ is not limited to the above. Any device that discharges the unit mounting body cut in units of RFID chips in the unit mounting body discharging apparatus 27 ′ may be any device, and the unit mounting body 9 that has been cut in advance is discharged from the discharge unit 28. It doesn't matter what you do. Alternatively, a cutter may be provided in the vicinity of the first roller 51 so that, for example, the strip-shaped film 9 ′ shown in FIG. 3 is supplied onto the first roller 51 while being cut.

Thus, according to the manufacturing apparatus of the said 1st, 2nd embodiment, the papermaking paper 7 (refer FIG. 5) which has arrange | positioned the unit mounting bodies 9 at arbitrary intervals can be manufactured. That is, it is possible to manufacture the papermaking paper 7 in which the interval between the RFID chips 1 is arbitrarily adjusted.
Further, the unit mounting body 9 used in the first and second embodiments is provided with a dewatering notch 10 so that dehydration can be performed quickly. As a result, a large unit mounting body can be made without worrying about the destruction of the paper layer. However, if the unit mounting body 9 is small in size, there is no fear of the paper layer breaking during pressing. The dewatering notch 10 may be omitted.
When the unit mounting body does not have the dewatering notch 10, the load in the drying process 25 is increased, but the same belt-like film 2 ′ as in the past can be used.

The dewatering notch 10 may be formed at any stage before paper making. For example, even if it is not formed at the stage of the strip-shaped film formed into a roll, it may be formed at the same time when the unit mounting body is formed by the unit mounting body supply device 27.
In the first and second embodiments, the first and second paper layers a and b are provided. However, the number of paper layers is not limited to two and may be further increased. In short, it is only necessary to supply a unit mounting body composed of RFID chip units between at least a pair of paper layers and make a sheet of paper, so that any number of paper layers can be provided outside the pair of paper layers a and b. It doesn't matter.
For example, when it is necessary to provide the third paper layer, it can be created as follows. The first paper layer a or the second paper layer b is provided by a circular net for scooping up the pulp slurry by providing third paper making means in front of the conveying direction of the first paper layer a and the second paper layer b. A third paper layer can be provided by attaching a pulp slurry to one side of the sheet. Similarly, a multi-layer paper layer can be formed.
