  Further, at the time of reading or writing as described above, the ID of the generated RFID label T and the information read from the IC circuit unit 151 of the RFID label T (or information written to the IC circuit unit 151) The correspondence relationship is stored in the route server 4 and can be referred to as necessary.

  FIG. 10 shows the creation of the above-described RFID label T, that is, the printed label label 110 after the cover film 103 is conveyed and the base tape 101 is bonded to the printed label 10 while the printing head 10 performs predetermined printing. 6 is a flowchart showing a control procedure executed by the transport / communication control unit 30A of the control circuit 30 when the tape 110 is cut for each RFID circuit element To to form the RFID label T.

  In FIG. 10, when the reading operation of the tag label producing apparatus 2 is performed, this flow is started. First, in step S <b> 105, print information to be printed on the RFID label T by the print head 10 input through the terminal 5 or the general-purpose computer 6 is read through the communication line 3 and the input / output interface 31.

  Thereafter, in step S110, there is no response from the RFID circuit element To, and a variable N for counting the number of retries (number of access attempts) and a flag F indicating whether communication is good or bad are initialized to zero.

  In step S115, control signals are output to the cartridge drive circuit 24 and the supply roller drive circuit 64, and the ribbon take-up roller 106, the pressure roller 107, and the first roll are driven by the drive force of the cartridge motor 23 and the supply roller motor 63. The roller 102 is rotationally driven (note that the rotational speed of the first roller at this time is adjusted by tension control described later in the tension controller 30B). As a result, the base tape 101 is fed out from the first roller 102 and supplied to the pressure roller 107, and the cover film 103 is fed out from the second roll 104. At this time, a control signal is output to the print drive circuit 25, the print head 10 is energized, and a predetermined area of the cover film 103 (for example, a wireless tag circuit arranged at equal intervals on the base tape 101 at a predetermined pitch). A print R such as a character, a symbol, or a barcode read in step S105 is printed on a region to be bonded to the back surface of the element To. Further, a control signal is output to the delivery roller motor 28 via the delivery roller drive circuit 29 to drive the delivery roller 17 to rotate. As a result, as described above, the base tape 101 and the cover film 103 after the printing are bonded and integrated by the pressure roller 107 and the sub-roller 109 to form a tag label tape 110 with print, and the cartridge body 100 is conveyed outward.

  After that, in step S120, the tag label tape 110 with print is only a predetermined value (for example, a transport distance that the RFID circuit element To to which the cover film 103 with the corresponding printing is bonded is reached the transport guide 13). Determine if it was transported. The conveyance distance determination at this time is, for example, based on the detection result by the photosensor 19 of the cut mark PM of the tape 110 provided at the tag label T position preceding the tag label T position currently being created. This may be done by counting the number of pulses output from the cartridge drive circuit 24 that drives the motor 23. If the determination is satisfied, the process proceeds to step S200.

  In step S200, for example, tag information reading processing is performed by specifying tag IDs (all or a part) acquired by a known method, and an inquiry signal (specific search signal or the like) for reading is transmitted to the RFID circuit element To. Then, a response signal including the wireless tag information is received and read (refer to FIG. 11 described later for details). It should be noted that if there is no fear of interference, such as a means for preventing erroneous communication is prepared separately, an unspecified search signal or search signal may be transmitted without specifying the tag ID. When step S200 is completed, the process proceeds to step S125.

  In step S125, it is determined whether or not flag F = 0. If the reading process is normally completed, F = 0 remains (see step S280 in the flow shown in FIG. 11 described later), so this determination is satisfied, and the routine goes to step S130.

  In step S130, a combination of the information read from the RFID circuit element To in step S200 and the print information already printed by the print head 10 corresponding to the information is sent via the input / output interface 31 and the communication line 3. The data is output via the terminal 5 or the general-purpose computer 6 and stored in the information server 7 or the route server 4. The stored data is stored and held in, for example, a database so that it can be referred to from the terminal 5 or the general-purpose computer 6 as necessary.

  Thereafter, the determination in step S135 is repeated until the printing on the area of the cover film 103 corresponding to the RFID circuit element To that is the processing target at this time is completed. After the printing is completed, the process proceeds to step S140.

  In step S125 described above, if the reading process is not normally completed for some reason, F = 1 is set (see step S280 in the flow shown in FIG. 11 described later), so the determination in S125 is satisfied. In step S137, a control signal is output to the print drive circuit 25 to stop energizing the print head 10 and stop printing. As described above, the fact that the RFID circuit element To is not a normal product is clearly displayed by stopping printing halfway, and then the process proceeds to step S140.

  In step S140, it is determined whether the printed tag label tape 110 is further conveyed and the cut mark PM on the release paper 101d is detected by the photosensor 19. If the determination is satisfied, the process moves to step S145.

  In step S145, control signals are output to the cartridge drive circuit 24, the delivery roller drive circuit 29, and the supply roller drive circuit 64 in response to the detection of the cut mark PM, and the cartridge motor 23, the delivery roller motor 28, and the supply roller use. The driving of the motor 63 is stopped, and the rotation of the ribbon take-up roller 106, the pressure roller 107, the first roller 102, and the feed roller 17 is stopped. As a result, the feeding of the base tape 101 from the first roller 102, the feeding of the cover film 103 from the second roll 104, and the conveyance of the printed tag label tape 110 by the feeding roller 17 are stopped, and the release tape 101d is provided. In addition, the cutting line CL is just positioned between the cutters of the cutter 105 (the base tape 101 and the equipment arrangement in the housing 9 are set in advance as such).

  Thereafter, in step S150, a control signal is output to the solenoid drive circuit 27 to drive the solenoid 26, and the printed tag label tape 110 is cut (divided) along the cutting line CL by using the blade of the cutter 15. As described above, at this time, for example, the RFID tag circuit element To to be processed and the print area of the cover film 103 corresponding thereto all sufficiently exceed the cutter 15, and by cutting the cutter 15, the RFID tag A label-like RFID label T on which the RFID tag information of the circuit element To is read and predetermined printing corresponding to the RFID tag information is performed is generated.

  Thereafter, the process proceeds to step S155, where a control signal is output to the delivery roller drive circuit 29, the drive of the delivery roller motor 28 is resumed, and the delivery roller 17 is rotated. As a result, the conveyance by the delivery roller 17 is resumed, and the RFID label T generated in a label shape in step S150 is conveyed toward the carry-out port 16 and is further discharged from the carry-out port 16 to the outside of the apparatus 2.

  FIG. 11 is a flowchart showing the detailed procedure of step S200 described above.

  In FIG. 11, first, in step S210, the tag ID (one of the tag IDs) of the RFID circuit element To that is specified in advance by a known method as described above and is a communication target (built in the generated RFID tag label). Part may be set).

  Thereafter, in step S220, a part of or all of the tag ID of the RFID circuit element To acquired in the above-described step S120 is designated, and a “Scroll ID” command (for reading information stored in the RFID circuit element To) ( Alternatively, a “Ping” command for obtaining a response from one or more predetermined RFID circuit elements may be output to the signal processing circuit 22. Based on this, a “Scroll ID” signal (or “Ping” signal) as access information is generated by the signal processing circuit 22 and transmitted to the RFID tag circuit element To that is the access target having the tag ID via the high-frequency circuit 21. Prompts for a reply. If it is not necessary to specify the tag ID as described above, step S210 is omitted, and a “Scroll All ID” command for requesting responses to all the RFID circuit elements is output to the signal processing circuit 22 in step S220. Then, a “Scroll All ID” signal is transmitted to the RFID circuit element To.

  Next, in step S230, a reply signal (RFID tag information such as article information) transmitted from the RFID tag circuit element To to be accessed corresponding to the “Scroll ID” signal is received via the antenna 14, and the high frequency signal is received. The data is taken in via the circuit 21 and the signal processing circuit 22.

  Next, in step S240, it is determined using a known error detection code (CRC code; Cyclic Redundancy Check, etc.) whether or not there is an error in the reply signal received in step S230.

  If the determination is not satisfied, the process moves to step S250, and 1 is added to N. Further, in step S260, N is a predetermined number of retries set in advance (in this example, 5 times. Other times may be set as appropriate). It is determined whether or not. If N ≦ 4, the determination is not satisfied and the routine returns to step S220 and the same procedure is repeated. If N = 5, the process proceeds to step S270, and an error display signal is output to the terminal 5 or the general-purpose computer 6 via the input / output interface 31 and the communication line 3 to display a reading failure (error), and in step S280. The aforementioned flag F = 1 is set, and this flow is finished. In this way, even if reading is unsuccessful, retry is performed up to a predetermined number of times (in this example, 5 times).

  When the determination in step S240 is satisfied, the reading of the RFID tag information from the RFID circuit element To to be read is completed, and this flow ends.

  Through the above routine, the RFID tag information of the IC circuit 151 can be accessed and read from the RFID tag circuit element To to be accessed in the cartridge 100. Further, if the RFID tag information of the IC circuit unit 151 cannot be read correctly within a predetermined number of times, it can be determined that the RFID circuit element To is damaged, and therefore, it is determined whether the RFID label is not defective. Can do.

  The main part of the present embodiment is that when the tension control of the base tape 101 is performed in the tag label producing apparatus 2 having the basic configuration and operation described above, the actual rotation angle (actual tension) of the tension arm 67 and the target rotation angle (target) The tension arm 67 is rotated by the air cylinder 62 using the deviation from the tension), whereby the tension control of the base tape 101 fed out from the first roll 102 is performed with good responsiveness. Hereinafter, the details will be described in order.

  FIG. 12 is an explanatory diagram showing the concept of the tension control.

  In FIG. 12, when the tension of the base tape 101 detected by the rotation angle of the tension arm 67 detected by the angle sensor 68 (see FIG. 2) is less than the target value, the supply roller motor 63 is used. The rotation speed of the first roller 102 in the feeding direction is relatively slow (in other words, the rotation speed is relatively negative). Further, the air pressure to the air cylinder 62 by the electropneumatic regulator 65 is controlled to be low, the piston 62a is drawn into the cylinder body 62 side, and the tension arm 67 is rotated so as to expand the tape transport path to the outer peripheral side ( “A” position in the figure). As a result, the tension of the base tape 101 is controlled in the increasing direction.

  Conversely, when the tension of the base tape 101 is excessively higher than the target value, the rotation speed of the supply roller motor 63 in the feeding direction of the first roller 102 is relatively increased (in other words, relative Gives the rotation speed to the + side). Further, the air pressure to the air cylinder 62 by the electropneumatic regulator 65 is controlled to be high, the piston 62a is pushed out from the cylinder main body 62 side, and the tension arm 67 rotates so as to dent the tape transport path to the inner peripheral side. . As a result, the tension of the base tape 101 is controlled in the decreasing direction.

  FIG. 13 is a functional block diagram conceptually showing a control system for performing the tension control. In FIG. 13, for example, when a tag label is created, the target tension value to of the base tape 101 is input via the terminal 5 or the general-purpose computer 6, and the tension control unit of the control circuit 30 is connected via the communication line 3 and the input / output interface 31. 30B is read. The tension control unit 30B includes a voltage conversion calculation unit 30Ba, a subtraction unit 30Bb, a motor speed command calculation unit 30Bc, and a tension air pressure command calculation unit 30Bd. The target tension to corresponds to the voltage conversion calculation unit 30Ba. After being converted to the target angle θo of the tension arm 67, it is input to the subtractor 30Bb.

  On the other hand, at this time, the detected rotation angle (actual angle) θ of the actual tension arm 67 is output after A / D conversion, and the actual angle θ is input to the subtractor 30Bb. Is done. In the subtraction unit 30Bb, the actual angle θ is subtracted from the target angle θo described above to obtain the angle deviation Δθ. The angle deviation Δθ is input to both the motor speed command calculation unit 30Bc and the tension air pressure command calculation unit 30Bd.

  The motor speed command calculation unit 30Bc executes a well-known PID control calculation (refer to FIG. 14 to be described later in detail) for calculating and adding the differential term, proportional term, and integral term of the angle deviation Δθ. A supply motor speed command signal V is generated. The supply motor speed command signal V is D / A converted by the supply roller drive circuit 64 described above, and then supplied to the supply roller motor 63 as a drive current.

  In the tension air pressure command calculation unit 30Bd, a predetermined calculation process (linear conversion in this example, see FIG. 14 described later in detail) is performed on the angle deviation Δθ, and the corresponding tension air pressure command signal P is thereby obtained. Generate. The tension air pressure command signal P is D / A converted by the regulator drive circuit 66 described above, and then supplied as a drive current to the electropneumatic regulator 65 of the air cylinder 62. Thus, the tension control of the base tape 101 is performed by the rotation speed control of the first roller 102 and the rotation control of the tension arm 67 based on the angle deviation Δθ.

  FIG. 14 is a flowchart showing a control procedure executed by the tension control unit 30B.

  In FIG. 14, first, in step S600, the voltage conversion calculation unit 30Ba calculates the target angle θo of the tension arm 67 based on the base tape target tension value to input as described above. Thereafter, the process proceeds to step S605, and the actual angle θ of the tension arm 67 from the angle sensor 68 is read.

  In step S610, the subtractor 30Bb calculates an angle deviation Δθ = θo−θ between the target angle θo calculated in step S600 and the actual angle θ read in step S605. That is, Δθ has a sign, and it is determined whether the air pressure is increased or decreased from the reference value in step S630, which will be described later, depending on whether the tension arm 67 is located inside or outside the tape conveyance path from the target position. .

  Thereafter, the process proceeds to step S620, and the motor speed command calculation unit 30Bc uses the gains kd, kp, and ki to use the differential term kd × dΔθ, the proportional term kp × Δθ, and the integral term ki × of the angle deviation Δθ. ∫Δθ is calculated, and these are added together to calculate the supply motor speed V.

  In step S630, the tension air pressure command calculation unit 30Bd performs linear conversion calculation on the angle deviation Δθ in this example, that is, A is an air pressure adjustment gain, B is a set reference air pressure (the tension arm 67 is As the air pressure at the reference angle, the tension air pressure P is calculated by P = −A × Δθ + B.

  Thereafter, the process proceeds to step S640, where the supply motor speed command signal V calculated in step S620 is output to the supply roller drive circuit 64, and in step S650, the tension air pressure command signal P calculated in step S630 is output to the regulator drive circuit. 66, and this flow is finished.

  In the above, the access information (“Scroll ID” signal, “Ping” signal, which will be described later) for the signal processing circuit 22 and the transmission unit 32 of the high frequency circuit 21 to access the information of the IC circuit unit described in each claim. (Program) signal, “Erase” signal, “Verify” signal, etc.) are generated and transmitted to the tag-side antenna via the device-side antenna to constitute information access means for accessing information in the IC circuit unit. Further, the tension control unit 30B of the control circuit 30 constitutes an advance / retreat control means for controlling the advance / retreat actuator based on the tension of the fed tape.

  As described above, in the tag label producing apparatus 2 of this embodiment, when producing the RFID label T, the base tape 101 and the printed cover film 103 are pressure-bonded by the pressure roller 107 and the sub-roller 109. The tag label 110 for printed tag label is generated, and the access information generated by the signal processing circuit 22 and the high frequency circuit 21 is transmitted to the antenna 152 of the RFID circuit element To via the antenna 14, and the RFID tag circuit element To Access to the information of the IC circuit unit 151 (reading of information in this example, writing of information in a modified example described later) is performed. As a result, for example, the RFID label T having a print that clearly indicates the contents stored in the IC circuit unit 151 can be created.

  The air cylinder 62 is controlled by the tension control unit 30B of the control circuit 30 according to the tension of the tape detected via the angle sensor 68 when the base tape 101 is transported for label production. The dancer roller 61 advances and retreats in the direction intersecting the conveyance direction of the base tape 101 in accordance with the advance and retreat. When the tension is too low, the dancer roller 61 can be moved so as to swell from the tape conveyance path in the outer circumferential direction, and the tension can be quickly increased. By moving in such a manner, the tension can be quickly reduced. In this way, by adjusting the tension increase / decrease by applying a force in a direction crossing the tape surface direction in which the tension is generated, only the rotation speed control on the supply roller (first roller 102 in this embodiment) side is performed. Compared with the case where the tension is adjusted with, the tension can be adjusted quickly and with good responsiveness.

  Further, in this embodiment, in particular, the tape tension is detected as the rotation angle of the tension arm 67 by the angle sensor 68, and the air cylinder 62 is driven forward / backward according to the tape tension, so that the tension can be adjusted reliably with good responsiveness. It can be carried out.

  The present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit and scope of the technical idea. Hereinafter, such modifications will be described.

(1) When using irregularly shaped rollers That is, although not shown, for example, as the dancer roller 61, a roller main body (cylindrical shape) that contacts the base tape 101 avoids contact with the RFID circuit element To. It is also possible to use one having a recess for making it or having a split structure in the axial direction. In this case, it is possible to prevent the durability of the RFID circuit element To of the base tape 101 from being adversely affected by the contact of the roller body of the dancer roller 61.

(2) In the case where information is written to the RFID circuit element In each of the above-described embodiments, the case where the present invention is applied to a RFID tag generation system that can only be read (not written) has been described as an example. The present invention may be applied to a RFID tag generation system that writes information to the IC circuit portion 151 of the RFID circuit element To.

  FIG. 15 is a flowchart showing a control procedure executed by the transport / communication control unit 30A of the control circuit 30 in this modification, and corresponds to FIG. 10 described above. The same steps as those in FIG. 10 are denoted by the same reference numerals.

  In FIG. 15, in step S <b> 105 </ b> A, information to be written in the IC circuit unit 151 of the RFID circuit element To and input to be printed on the RFID label T by the print head 10, which is input via the terminal 5 or the general-purpose computer 6. Is read via the communication line 3 and the input / output interface 31. After this procedure is completed, the process proceeds to step S110A, and in addition to the aforementioned variable N and flag F, a variable M (details will be described later) is initialized to zero.

  Thereafter, the process proceeds to step S200A through steps S115 and S120 similar to those in FIG. In step S200A, for example, after performing memory initialization (erasing) for writing tag information by designating a tag ID (all or a part) acquired by a known method, the RFID tag circuit element To (See FIG. 16 to be described later for details). When step S200A is completed, the process proceeds to step S125 as in FIG.

  In step S125, it is determined whether or not the flag F = 0 as in FIG. 10, and when this determination is satisfied, the process proceeds to step S130A.

  In step S130A, the combination of the information written in the RFID circuit element To in step S200A and the print information already printed by the print head 10 corresponding to the information is sent via the input / output interface 31 and the communication line 3. The data is output via the terminal 5 or the general-purpose computer 6 and stored in, for example, the route server 4 as in step S130 of FIG. The stored data is stored and held so that it can be referred to from the terminal 5 or the general-purpose computer 6 as necessary.

  The subsequent procedure is substantially the same as that shown in FIG.

  FIG. 16 is a flowchart showing the detailed procedure of step S200A described above.

  In FIG. 16, first, in step S310, the tag ID (tag ID of the tag ID) of the RFID circuit element To specified as a communication target (built in the generated RFID tag label) specified in advance by a known method as described above. Some may be set).

  Thereafter, in step S320, the tag ID (all or a part) is designated and an “Erase” command for initializing information stored in the memory unit 157 of the RFID circuit element To is output to the signal processing circuit 22. Based on this, an “Erase” signal as access information is generated by the signal processing circuit 22 and transmitted to the RFID tag circuit element To to be written through the high frequency circuit 21 to initialize the memory unit 157.

  In step S330, a “Verify” command for confirming the contents of the memory unit 157 is output to the signal processing circuit 22 in the same manner as described above. Based on this, a “Verify” signal as access information is generated by the signal processing circuit 22 and transmitted to the RFID circuit element To as an information write target via the high frequency circuit 21 to prompt a reply. Thereafter, in step S340, a reply signal transmitted from the RFID tag circuit element To to be written in response to the “Verify” signal is received via the antenna 14 and taken in via the high frequency circuit 21 and the signal processing circuit 22.

  Next, in step S350, based on the reply signal, information in the memory unit 157 of the RFID circuit element To is confirmed, and it is determined whether or not the memory unit 157 has been normally initialized.

  If the determination is not satisfied, the process proceeds to step S360, and 1 is added to M. Further, in step S370, M is a predetermined number of retries set in advance (in this example, 5 times. Other times may be set as appropriate). It is determined whether or not. If M ≦ 4, the determination is not satisfied and the routine returns to step S320 and the same procedure is repeated. When M = 5, the process proceeds to step S380, where an error display signal is output to the terminal 5 or the general-purpose computer 6 via the input / output interface 31 and the communication line 3, and a corresponding writing failure (error) display is performed. In this way, even if initialization is not successful, retry is performed up to five times. When step S380 ends, the process proceeds to step S385. In step S385, the aforementioned flag F = 1 is set, and the process proceeds to step S460.

  On the other hand, when the determination in step S350 is satisfied, the process proceeds to step S390, and a “Program” command for writing desired data in the memory unit 157 is output to the signal processing circuit 22. Based on this, the signal processing circuit 22 generates a “Program” signal as access information including information to be written in the IC circuit unit 151 of the RFID circuit element To that is input via the terminal 5 or the general-purpose computer 6. The information is transmitted to the RFID circuit element To as the information writing target via the high frequency circuit 21, and the information input through the terminal 5 or the general-purpose computer 6 is written in the memory unit 157.

  Thereafter, a “Verify” command is output to the signal processing circuit 22 in step S400. Based on this, a “Verify” signal as access information is generated by the signal processing circuit 22 in the same manner as described above, and is transmitted to the RFID circuit element To as an information write target via the high frequency circuit 21 to prompt a reply. Thereafter, in step S 410, a reply signal transmitted from the RFID tag circuit element To to be written in response to the “Verify” signal is received via the antenna 14 and taken in via the high-frequency circuit 21 and the signal processing circuit 22.

  Next, in step S420, based on the reply signal, the information stored in the memory unit 157 of the RFID circuit element To is confirmed, and whether or not the transmitted predetermined information is normally stored in the memory unit 157. Determine whether.

  If the determination is not satisfied, the process moves to step S430, and 1 is added to N. Further, in step S440, N is a predetermined number of retries set in advance (in this example, 5 times. Other times may be set as appropriate). It is determined whether or not. If N ≦ 4, the determination is not satisfied and the routine returns to step S390 and the same procedure is repeated. If N = 5, the process proceeds to the above-described step S380, and similarly, the writing failure (error) display corresponding to the terminal 5 or the general-purpose computer 6 is displayed, and the above-described flag F = 1 is set in step S385, and this flow is finished. To do. In this way, even if information writing is not successful, retry is performed up to five times.

  On the other hand, if the determination in step S420 is satisfied, the process moves to step S450, and a “Lock” command is output to the signal processing circuit 22. Based on this, a “Lock” signal is generated in the signal processing circuit 22 in the same manner as described above, and is transmitted to the RFID circuit element To as the information writing target via the high-frequency circuit 21, and a new signal is sent to the RFID circuit element To. Information writing is prohibited. As a result, the writing of the RFID tag information to the RFID circuit element To to be written is completed, and the RFID circuit element To is discharged as described above. When step S450 ends, this flow ends.

  According to the above routine, desired information can be written in the IC circuit section 151 for the RFID tag circuit element To to be accessed in the cartridge 100.

  As described above, in the present modification, the wireless tag generation system for writing the wireless tag information has substantially the same effect as the above embodiment.

The “Scroll” used above
It is assumed that the “ID” signal, “Ping” signal, “Scroll All ID” signal ”,“ Erase ”signal,“ Verify ”signal,“ Program ”signal, and the like comply with the specifications established by the EPC global. EPC global is a non-profit corporation established jointly by the International EAN Association, which is an international organization of distribution codes, and the United Code Code Council (UCC), which is an American distribution code organization. Note that signals conforming to other standards may be used as long as they perform the same function.

  A second embodiment of the present invention will be described with reference to FIGS. The present embodiment is an embodiment in which the tape supply device according to the present invention is applied to a base tape manufacturing apparatus (small winding apparatus) having the above-described laminated structure. Portions equivalent to those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted as appropriate.

  FIG. 17 is a conceptual diagram showing the overall schematic structure of the base tape manufacturing apparatus provided with the tape supply apparatus of the present embodiment. In FIG. 17, this base tape manufacturing apparatus has a first tape 200 </ b> A (detailed structure will be described later) and a second tape 200 </ b> B (detailed structure will be described later) bonded together and wirelessly between these two tapes to be bonded together.

  In the first tape unwinding roller 211, the first tape 200A is wound around a reel member 211a driven by the first tape unwinding roller driving motor 212. Similarly, the second tape unwinding roller 213 has the second tape 200B wound around a reel member 213a driven by the second tape unwinding roller driving motor 214.

Details will be described later.

  The tape thus bonded and further inserted with the tag is the release paper (separator) made of the release paper 200Bd provided in the second tape 200B at the rollers 240A and 240B located on the downstream side of the transport rollers 219A and 219B. ) 209 and a base tape 210 made up of other parts.

  FIG. 19 is a cross-sectional view taken along the SS line in FIG. 17 showing the detailed cross-sectional structure of the base tape 210 produced as described above. After the RFID tag Tg is inserted and arranged between the first tape 200A having the four-layer structure and the second tape 200B having the four-layer structure, the base paper 210 is separated from the release paper 200Ba as described above by the separator take-up roller. In this example, a ten-layer structure is formed by winding and removing at 217. That is, from the side wound inside the base tape winding roller 215 (upper side in FIG. 19) toward the opposite side (lower side in FIG. 19), the release paper 200Ad, the adhesive layer 200Ac, the base film 200Ab, The adhesive material layer 200Aa, the tag base material 160, the antenna 152, the IC chip holding member 161, the adhesive material layer 200Ba, the tape base material layer 200Bb, and the adhesive material layer 200Bc are laminated in this order.

  FIG. 20 is a flowchart illustrating a control procedure executed by the conveyance / insertion control unit 230A of the controller 230 described above.

  In FIG. 20, first, in step S505, tape driving is started in response to an operation signal for starting the production of a base tape input via an operation means (not shown). That is, a control signal is output to the transport roller drive circuit 235, and the first tape 200A and the second tape 200B are fed from the first tape unwind roller 211 and the second tape unwind roller 213 by the driving force of the transport roller drive motor 220. Drive. At the same time, control signals are also output to the first and second tape take-up roller drive circuits 231, 232, the base tape take-up roller drive circuit 233, and the separator take-up roller drive circuit 234. The two tape take-up roller drive motors 212 and 213, the base tape take-up roller drive motor 216, and the separator take-up roller drive motor 218 are also driven to control the tension of each corresponding tape. It is controlled by the tension controller 230B (details will be described later). As a result, the first tape 200A is fed out from the first tape unwinding roller 211 and the second tape 200B is unwound from the second tape unwinding roller 213, and is bonded and integrated by the bonding rollers 225A and 225B. It is conveyed toward the conveying rollers 219A and 219B.

  Thereafter, the process proceeds to step S510, and it is determined whether or not the tape conveyed as described above has reached the position where the wireless tag Tg is bonded. The determination at this time is based on the detection result by the photo sensor 228 of, for example, marks (identifiers) provided at a predetermined position on the surface of the first tape 200A at an equal pitch, for example, the transport roller drive motor 220 which is a pulse motor, for example. May be performed by counting the number of pulses output from the conveying roller driving circuit 235 for driving the. If the determination is satisfied, the process moves to step S515.

  In step S515, a control signal is output again to the transport roller drive circuit 235, the drive of the transport roller drive motor 220 is stopped, and the first tape 200A from the first tape unwind roller 211 and the second tape unwind roller 213, The feeding drive of the second tape 200B is stopped (at this time, the first and second tape winding roller driving motors 212 and 213, the base tape winding roller driving motor 216, and the separator winding roller driving motor 218 are described above. The drive is automatically stopped by tension control (details will be described later).

  In such a state that the tape drive is stopped (at a predetermined tag insertion position), a control signal is output to the tag inserter 226 in the subsequent step S520, and the RFID circuit including the IC circuit unit 151 and the antenna 152 described above is output. A wireless tag Tg including the element To is inserted. Thereafter, the process proceeds to step S525, and similarly to step S505, a control signal is output to the conveyance roller drive circuit 235, and the conveyance drive of the first tape 200A and the second tape 200B is resumed by the driving force of the conveyance roller drive motor 220.

  Thereafter, the process proceeds to step S530, and it is determined whether or not the base tape 210 wound by the base tape winding roller 215 has reached a predetermined winding end position. Specifically, the base tape 210 that is separated from the separator 209 by the rollers 240A and 240B and is taken up by the base tape take-up roller 215 while the wireless tags T are inserted at predetermined equal intervals as described above. For example, the determination is made based on whether or not an appropriate mark (identifier) indicating the winding end position provided in advance at a predetermined location of the release paper 200Ad is detected by the photo sensor 229 downstream of the cutter 227. Immediately after the start of normal winding, this determination is not satisfied, and the process returns to step S510 and the same procedure is repeated.

  Step S510 → Step S515 → Step S520 → Step S525 → Step S530 → Step S510 →... As described above, the base tape 210 wound up by the base tape take-up roller 215 has a predetermined amount (length). If the mark (identifier) indicating the winding end position of the release paper 200Ad is detected by the photosensor 229, the determination is satisfied, and the routine goes to Step S535.

  In step S535, as in step S515, the control signal is output again to the transport roller drive circuit 235, the drive of the transport roller drive motor 220 is stopped, and the first tape unwinding roller 211 and the second tape unwinding roller 213 start. The feeding drive of the first tape 200A and the second tape 200B is stopped.

  Thereafter, the process proceeds to step S540, where a control signal is output to the solenoid drive circuit 237 to drive the solenoid 236, and the base tape 210 is cut (divided) using the cutter 227. Thereby, the roll around which the base tape 210 having a predetermined length is wound is completed.

  The main part of this embodiment is the above-described first embodiment when the tension control of the first tape 200A, the second tape 200B, the base tape 210, and the separator 209 is performed in the base tape manufacturing apparatus having the basic configuration and operation described above. Similarly, the tension arms 267A-D are rotated by the air cylinders 262A-D using the deviation between the actual rotation angle (actual tension) and the target rotation angle (target tension) of the tension arms 267A-D, The purpose is to control the tension of the tapes 200A, 200B, 209, and 210 with high responsiveness.

  FIGS. 21A and 21B are explanatory views showing the concept of the tension control and corresponding to FIG. 12 of the first embodiment.

  FIG. 21A shows the tension control behavior on the first and second tape unwinding rollers 211 and 213, and the rotation angles of the tension arms 267A and 267C detected by the angle sensors 268A and 268C (see FIG. 17). When the tension of the first or second tape 200A, 200B detected by the above is insufficient below the target value, the first or second tape winding by the first or second tape unwinding roller drive motors 212, 214 is performed. The rotational speed of the delivery rollers 211 and 213 in the feeding direction is relatively slow (in other words, the rotational speed toward the minus side is relatively given). In addition, the air pressure to the air cylinders 262A, 262C by the electropneumatic regulators 265A, 265C is controlled to be high, and the piston 262a protrudes from the cylinder body 262b side, and the tension arms 267A, 267C expand the tape transport path to the outer peripheral side. ("A" position in the figure). As a result, the tension of the first or second tape 200A, 200B is controlled in the increasing direction.

  On the contrary, when the tension of the first or second tape 200A, 200B is higher than the target value, the first or second tape unwinding by the first or second tape unwinding roller driving motors 212, 214 is performed. The rotation speed of the rollers 211 and 213 in the feeding direction is relatively increased (in other words, the rotation speed is relatively increased to the + side). Further, the air pressure to the air cylinders 262A, 262C by the electropneumatic regulators 265A, 265C is controlled to be low, and the piston 262a is drawn into the cylinder body 262 side, and the tension arms 267A, 267C move the tape transport path to the inner peripheral side. It rotates so as to be recessed ("B" position in the figure). As a result, the tension of the first or second tape 200A, 200B is controlled in the decreasing direction.

  On the other hand, FIG. 21B shows the tension control behavior on the base tape take-up roller 215 and separator take-up roller 217 side, and the tension arms 267B and 267D detected by the angle sensors 268B and 268D (see FIG. 17). When the tension of the base tape 210 or the separator 209 detected by the rotation angle is less than the target value, the base tape by the base tape take-up roller drive motor 216 or the separator take-up roller drive motor 218 The rotational speed in the winding direction by the winding roller 215 or the separator winding roller 217 is relatively increased (in other words, a rotational speed relatively to the + side is given). Further, the air pressure to the air cylinders 262B and 262D by the electropneumatic regulators 265B and 265D is controlled to be high so that the piston 262a protrudes from the cylinder body 262b side, and the tension arms 267B and 267D expand the tape transport path to the outer peripheral side. ("C" position in the figure). As a result, the tension of the base tape 210 or the separator 209 is controlled in the increasing direction.

  On the contrary, when the tension of the base tape 210 or the separator 209 is larger than the target value, the base tape take-up roller 215 by the base tape take-up roller drive motor 216 or the separator take-up roller drive motor 218. Alternatively, the rotation speed in the winding direction by the separator winding roller 217 is relatively slow (in other words, a relatively negative rotation speed is given). Also, the air pressure to the air cylinders 262B, 262D by the electropneumatic regulators 265B, 265D is controlled to be low, the piston 262a is drawn into the cylinder body 262 side, and the tension arms 267A, 267C move the tape transport path to the inner peripheral side. It rotates so as to be recessed ("D" position in the figure). As a result, the tension of the base tape 210 or the separator 209 is controlled in the decreasing direction.

  FIG. 22 is a functional block diagram conceptually showing a control system for performing the tension control, and corresponds to FIG. 13 of the first embodiment. In FIG. 22, for example, at the start of manufacture of the base tape 210, the target tension value to of each tape (first tape 200A, second tape 200B, base tape 210, separator 209) input via an operating means (not shown) or the like. Is input and read into the tension control unit 230B of the controller 230. Similarly to the above, the tension control unit 230B includes a voltage conversion calculation unit 230Ba, a subtraction unit 230Bb, a motor speed command calculation unit 230Bc, and a tension air pressure command calculation unit 230Bd, and the target tension to is the voltage conversion calculation unit 230Ba. Is converted into the target angle θo of the tension arms 267A to 267D corresponding to each tape and then input to the subtracting unit 230Bb.

  On the other hand, at this time, the angle sensors 268A-D corresponding to the respective tapes are output after the detected actual rotation angles (actual angles) θ of the tension arms 267A-D are respectively A / D converted, The actual angle θ is input to the subtracting unit 230Bb. In the subtracting unit 230Bb, each actual angle θ is subtracted from each target angle θo described above to obtain an angle deviation Δθ. The angle deviation Δθ is input to both the motor speed command calculation unit 230Bc and the tension air pressure command calculation unit 230Bd.

  The motor speed command calculation unit 230Bc executes a well-known PID control calculation (refer to FIG. 23 described later for details) that calculates and adds the differential term, proportional term, and integral term of the angle deviation Δθ. Motor speed command signal V to each motor (first tape winding roller drive motor 212, second tape winding roller drive motor 214, base tape winding roller drive motor 216, separator winding roller drive motor 218). Generate. This supply motor speed command signal V is a drive circuit for each motor described above (first tape winding roller driving circuit 231, second tape winding roller driving circuit 232, base tape winding roller driving circuit 233, separator winding roller). After being D / A converted by the drive circuit 234), it is supplied to each of the roller motors 212, 214, 216, 218 as a drive current.

  In the tension air pressure command calculation unit 230Bd, a predetermined calculation process (linear conversion in this example, see FIG. 23 described later in detail) is executed for the angle deviation Δθ, and thereby each corresponding motor (first tape winding) is executed. A tension air pressure command signal P related to the take-out roller drive motor 212, the second tape take-up roller drive motor 214, the base tape take-up roller drive motor 216, and the separator take-up roller drive motor 218) is generated. The tension air pressure command signal P is D / A converted by the regulator drive circuits 266A to 266D described above, and then supplied to the corresponding electropneumatic regulators 265A to 265D of the air cylinders 262A to 262D as drive currents. Thus, the tension control of each tape 200A, 200B, 210, 209 is performed by the rotational speed control of each of the rollers 211, 213, 215, 217 and the rotation control of the tension arms 267A-D based on the angle deviation Δθ.

  FIG. 23 is a flowchart showing a control procedure executed by the tension control unit 230B, and corresponds to FIG. 14 of the first embodiment.

  23, first, in step S700, each of the tension arms 267A to 267D is based on the base tape target tension value to as input by the voltage conversion calculation unit 230Ba as described above, similarly to step S600 of FIG. The target angle θo is calculated. Thereafter, the process proceeds to step S705, and the actual angles θ of the tension arms 267A to 267D from the angle sensors 268A to 268D are read as in step S605.

  In step S710, as in step S610, the subtraction unit 230Bb calculates an angle deviation Δθ = θo−θ between the target angle θo calculated in step S700 and the actual angle θ read in step S705. To do. Δθ in this case also has the same sign as in the first embodiment, and step S730, which will be described later, depends on whether the tension arms 267A to 267D are inside or outside the tape transport path from the target position. To decide whether to increase or decrease the air pressure from the reference value.

  Thereafter, the process proceeds to step S720, and similarly to step S620 of the first embodiment, the motor speed command calculation unit 230Bc uses the gains kd, kp, ki and the differential term kd × dΔθ of the angle deviation Δθ. The proportional term kp × Δθ and the integral term ki × ∫Δθ are calculated, and these are added together to calculate the motor speed V of each of the motors 212, 214, 216, 218, respectively.

  In step S730, as in step S630, the tension air pressure command calculation unit 230Bd performs a linear conversion operation on the angle deviation Δθ in this example, that is, A is an air pressure adjustment gain, and B is a set reference air. As the pressure (the air pressure when the tension arms 267A to 267D are at the reference angle), the tension air pressure P is calculated by P = −A × Δθ + B.

  Thereafter, the process proceeds to step S740, and the motor speed command signal V calculated in step S720 is output to the drive circuits 231, 232, 233, and 234 corresponding to the motors 212, 214, 216, and 218, and further in step S750, The tension air pressure command signal P calculated in step S730 is output to the regulator drive circuit 66, and this flow ends.

  In the above, the tension control unit 230B of the controller 230 constitutes the advance / retreat control means for controlling the advance / retreat actuator based on the tension of the fed tape, and the transport / insertion control unit 230A is a position to attach the RFID circuit element. At times, the conveyance of the tape is stopped, the attachment is performed, and the conveyance roller driving means and the tag attachment means are cooperatively controlled so as to resume the conveyance of the tape after the completion of the attachment.

  As described above, in the base tape manufacturing apparatus of the present embodiment, when the base tape 210 is manufactured, the first tape 200A is mainly driven by the transport driving force of the transport rollers 219A and 219B. 211 is fed out and supplied to the laminating rollers 225A and 225B. Similarly, the second tape 200B fed from the second tape unwinding roller 213 is also supplied to the bonding rollers 225A and 225B. When the first tape 200A and the second tape 200B are pasted by the laminating rollers 225A and 225B, the RFID tag Tg is sequentially inserted between the first tape 200A and the second tape 200B by the tag inserter 226. . Then, the tape having such a multilayer laminated structure is transported further downstream than the transport rollers 219A and 219B, and the release paper (separator) 209 is separated and removed by the rollers 240A and 240B, and the base tape 210 composed of the other portions. Is wound around the base tape winding roller 215. Thereby, the base tape 210 provided with the RFID circuit elements To at predetermined regular intervals in the tape longitudinal direction can be manufactured.

  Then, when the first tape 200A, the second tape 200B, the base tape 210, and the separator 209 for producing the label are conveyed, the tension of the controller 230 according to the tension of the tape detected through the angle sensors 268A to 268D. The air cylinders 262A to 262D are controlled by the control unit 230B, and the dancer rollers 221, 222, 223, and 224 advance and retreat in the direction intersecting with the transport direction of the tapes 200A, 200B, 210, and 209 according to the advance and retreat of the tension arms 267A to 267D. To do. When the tension is excessively small, the dancer rollers 221, 222, 223, and 224 are moved so as to swell in the outer circumferential direction from the tape conveyance path, so that the tension can be quickly increased. , 224 is moved so as to reduce the bulge in the outer circumferential direction from the tape conveyance path, whereby the tension can be quickly reduced. In this way, by adjusting the tension increase / decrease by applying a force in a direction crossing the tape surface direction in which the tension is generated, the supply roller (the first tape unwinding roller 211 and the second tape in this embodiment) is adjusted. Compared with the case where the tension is adjusted only by the rotational speed control on the unwinding roller 213) side, the tension can be adjusted quickly and with good responsiveness.

  Further, in the present embodiment, as in the first embodiment, the tape tension is detected by the angle sensors 268A-D as the rotation angles of the tension arms 267A-D, and the air cylinders 262A-D are controlled according to the tape tension. By driving forward and backward, the tension can be adjusted reliably with good responsiveness.
