The present invention relates to an electronic circuit printing method and apparatus for printing an electronic circuit at a contact point with a counter cylinder.

  In printing to print an electronic circuit on a substrate such as a film, the printed matter on which the first circuit is printed may be dried, the insulating film may be applied and dried thereon, and the second circuit may be printed thereon. . In this case, the second circuit needs to be printed with accurate alignment with the printed first circuit.

  For this purpose, usually, a reference mark (register mark) is printed together with the circuit when the circuit is printed for the first time, the position of the reference mark is detected, and the second circuit is adjusted in accordance with the detected position of the reference mark. Try to print.

  The background art described above is not publicly known. Further, the applicant has not been able to find prior art documents related to the present invention by the time of filing. Therefore, prior art document information is not disclosed.

  However, in the printing that prints the electronic circuit on the base material, the base material is an easily stretchable member such as a film, and the base material is greatly stretched and dried by heat once. Because the degree is different, just by aligning the position of the printing cylinder with the position of the detected fiducial mark as in conventional general printing, the circuit printed the second time can be accurately changed to the circuit printed the first time. There was a problem of not overlapping.

  The present invention has been made to solve such problems, and the object of the present invention is to provide a circuit printed at the first time and a circuit printed at the second time regardless of the degree of expansion and contraction of the base material. It is an object of the present invention to provide an electronic circuit printing method and apparatus capable of accurately aligning the position of the electronic circuit.

In order to achieve such an object, the present invention uses each section of the belt-shaped body made of the base material that is easily stretched and processed in the pretreatment process as a printing material, and the belt-shaped body is conveyed. In an electronic circuit printing method in which an electronic circuit is printed at a contact point between a printing cylinder and a counter cylinder on each substrate to be printed, a first reference mark is added to each substrate to be printed in a preprocessing step.

The rotation speed during printing of the cylinder is adjusted.

As a result, in the present invention, the printing material expansion / contraction ratio between the first reference marks obtained from the distance between the first reference marks (contraction ratio before printing of the printed material) is taken into account. Thus, the rotation speed of the printing cylinder is adjusted so that the printing of the electronic circuit (second circuit) on each substrate (first circuit) is accurately overlapped regardless of the degree of expansion and contraction of the base material. Can be performed.

  In the present invention, in the pretreatment step, a second reference mark larger than the first reference mark is further added to each of the printed materials, and the conveyance path of the printed material to the contact point between the printing cylinder and the counter cylinder is set. A second imaging unit having a wider imaging range than the first imaging unit is provided at a position farther from the opposite contact point than the first imaging unit in the middle, and an area including the second reference mark of the printed material is imaged.

A smaller first reference is obtained by imaging a narrow range of the printed material (first circuit) with a first imaging means (high resolution camera) having a narrow imaging range according to the detected position of the detected second reference mark. The position of the mark is detected, and the electronic circuit (second circuit) can be accurately printed on the substrate (first circuit) in accordance with the detected position of the first reference mark.

[Operation of drive controller]
Next, the operation of the drive control apparatus 200 in the electronic circuit printing apparatus will be described with the operation of the deviation amount detection apparatus 300.

  In the following operations, the CPU 201 of the drive control device 200 and the CPU 301 of the deviation amount detection device 300 write various data obtained by calculation into the memory M or read various data from the memory M as necessary. However, here, in order to avoid complicated explanation and because it is clear from the name of the memory M and the symbols shown in the memory M, the explanation of the read / write operation to the memory M is omitted. In some cases.

  The CPU 201 of the drive control apparatus 200 reads the printing speed Vs from the memory M1 (FIG. 12: Step S101), calculates the rotation speed VIr of the reference impression cylinder driving motor from the read printing speed Vs (Step S102). The calculated reference rotational speed VIr of the impression cylinder drive motor is written in the memory M2 (step S102), and is output to the impression cylinder drive motor driver 208 via the D / A converter 211 (step S103). As a result, the impression cylinder 3 rotates at the reference rotation speed VIr.

  The CPU 201 calculates the reference plate cylinder / rubber cylinder driving motor rotation speed VPr from the printing speed Vs, and writes the calculated reference cylinder / rubber cylinder driving motor rotation speed VPr to the memory M3. (Step S104), and output to the plate cylinder / rubber cylinder driving motor driver 215 via the D / A converter 218 (Step S105). As a result, the plate cylinder 1 and the rubber cylinder 2 rotate at the reference rotation speed VPr.

  Further, as an initial setting, the CPU 201 writes “2” as a value indicating that the phase deviation correction by the first register mark is not completed in the memory M4 (step S106), and the phase deviation by the second register mark in the memory M5. “2” is written as a value indicating that the correction is not completed (step S107).

[Image capture command of WG camera to deviation detection device from drive control device]
Then, the CPU 201 reads the count value from the impression cylinder rotation phase detection counter 210 (FIG. 13: step S108), and based on the read count value of the impression cylinder rotation phase detection counter 210, the current rotation phase ψ _{R of the} impression cylinder. Is calculated (step S109). Then, the reference imaging position PWGr of the WG camera is read from the memory M8 (step S110), and it is confirmed whether or not the current rotation phase ψ _R of the impression cylinder is at the reference imaging position PWGr of the WG camera (step S111).

When the CPU 201 repeats the processing operations in steps S108 to S111 and confirms that the current rotation phase ψ _R of the impression cylinder has reached the reference imaging position PWGr of the WG camera (YES in step S111), the rotation count of the printing press is counted. The enable signal and the reset signal are output to the counter 213 (step S112), and the output of the reset signal to the counter 213 for counting the number of rotations of the printing press is stopped (step S113). As a result, the counter 213 for counting the number of rotations of the printing press starts counting from zero.

  The CPU 201 transmits the imaging command of the WG camera to the deviation amount detection device 300 simultaneously with the start of counting from zero of the counter 213 for counting the number of rotations of the printing press (step S114), and sends a response from the deviation amount detection device 300. Wait (steps S115 and S117 (FIG. 14)).

  If a signal without the first register mark is transmitted from the deviation amount detection device 300 (YES in step S115), the CPU 201 transmits a signal reception completion signal without the first register mark to the deviation amount detection device 300. (Step S116), the process returns to Step S108.

  If the displacement amount detection device 300 transmits the displacement amount Δx1 in the X direction and the displacement amount Δy1 in the Y direction of the first register mark (YES in step S117), the CPU 201 has transmitted from the displacement amount detection device 300. The shift amount Δx1 in the X direction and the shift amount Δy1 in the Y direction of the first register mark are written in the memories M9 and M10 (step S118).

[Image of printed material by WG camera (detection of shift amount of first register mark by shift amount detection device)]
When the imaging command for the WG camera is sent from the drive control device 200 (FIG. 38: YES in step S301), the CPU 301 of the deviation amount detection device 300 outputs the imaging command to the WG camera 304 (step S302). Thereby, at the timing when the imaging command of the WG camera is sent from the drive control device 200, that is, at the timing when the current rotation phase ψ _R of the impression cylinder is located at the reference imaging position PWGr of the WG camera, the WG camera 304 The image of the printing material on the web 4 is conveyed.

  When image data is sent from the WG camera 304 (YES in step S303), the CPU 301 sets the count value Y in the memory M51 to 1 (step S304), and sets the count value X in the memory M52 to 1 (step S305). ), The imaging data at the pixel position specified by the count values X and Y from the WG camera 304 is written into the address position (X, Y) of the memory M53 (step S306).

  Then, the CPU 301 adds 1 to the count value X in the memory M52 (FIG. 39: Step S307), reads the number of pixels a in the horizontal direction of the WG camera in the memory M54 (Step S308), and counts in Step S309. The processing operations in steps S306 to S309 are repeated until X exceeds the number of pixels a in the left-right direction of the WG camera.

  If the count value X exceeds the number of pixels a in the left-right direction of the WG camera (YES in step S309), 1 is added to the count value Y in the memory M51 (step S310), and the top of the WG camera in the memory M55 is added. The number of pixels b in the direction is read (step S311), and the processing operations in steps S305 to S312 are repeated until the count value Y exceeds the number of pixels b in the vertical direction of the WG camera in step S312.

  Thereby, the imaging data of the a × b pixels from the WG camera 304 is stored in the memory M53. Here, as shown in FIG. 53 (a), imaging data of a wide area including the first register mark RM1 of the first substrate # 1 is stored in the memory M53 as imaging data of a × b pixels. And

  In the memory M58, as shown in FIG. 53 (b), c × d pixel data of the first register mark RM1 is stored as pattern matching data. Further, the vertical direction of the WG camera 304 is a flow direction of the web 4, and the left-right direction of the WG camera 304 is a direction orthogonal to the flow direction of the web 4.

  Next, the CPU 301 sets the count value Y in the memory M51 to 1 (step S313), sets the count value X in the memory M52 to 1 (step S314), and sets the count value N in the memory M56 to 1 (FIG. 40: In step S315), the count value M in the memory M57 is set to 1 (step S316).

  Then, the imaging pixel data of the WG camera at the address position (X + M−1, Y + N−1) in the memory M53 is read (step S317), and the first register mark at the address position (M, N) in the memory M58 is read. The pixel data is read (step S318), and the read pixel data of the WG camera at the address position (X + M-1, Y + N-1) in the memory M53 and the (M, N) address position in the memory M58 are read. It is confirmed whether or not the pixel data of one register mark matches (see step S319, FIGS. 53A and 53B).

  Here, the image data of the WG camera at the address position (X + M−1, Y + N−1) in the memory M53 and the pixel data of the first register mark at the address position (M, N) in the memory M58 are identical. If not (NO in step S319), any pixel data of the imaging data of the WG camera 304 from the address (X, Y) to the address (X + c-1, Y + d-1) at that time is stored in the first register. Unlike the mark pixel data, there is no first register mark in the range starting from the address (X, Y), so the CPU 301 adds 1 to the count value X in the memory M52 (FIG. 41: step S320). ) Read the horizontal pixel number a of the WG camera in the memory M54 and the horizontal pixel number c of the first register mark in the memory M59 (step). S321, S322), in step S323 until the count value X exceeds "a-c + 1", and repeats the processing operation in steps S315～S323.

  During this processing operation, if the count value X exceeds “a−c + 1” (YES in step S323), the left and right ends of the image data of the WG camera 304 have been exceeded, so the CPU 301 stores the memory M51 in the memory M51. 1 is added to the count value Y (step S324), and the vertical pixel count b of the WG camera in the memory M55 and the vertical pixel count d of the first register mark in the memory M60 are read (steps S325 and S326). ), The processing operations of steps S314 to S327 are repeated until the count value Y exceeds “b−d + 1” in step S327.

  During this processing operation, the imaging pixel data of the WG camera at the address position (X + M−1, Y + N−1) in the memory M53 and the pixel data of the first register mark at the address position (M, N) in the memory M58. Are confirmed (FIG. 40: YES in step S319), the CPU 301 adds 1 to the count value M in the memory M57 (step S330), and the left and right of the first register mark are read from the memory M59. The number of pixels c in the direction is read (step S331), and the processing operations of steps S317 to S332 are repeated until the count value M exceeds the number c of pixels in the left and right direction of the first register mark in step S332 (FIG. 42).

  When the count value M exceeds the left-right pixel count c of the first register mark (YES in step S332), the CPU 301 adds 1 to the count value N in the memory M56 (step S333), and the first value is read from the memory M60. The pixel number d in the vertical direction of the register mark is read (step S334), and the processing operations in steps S316 to S335 are repeated until the count value N exceeds the pixel number d in the vertical direction of the first register mark in step S335.

  In this manner, the CPU 301 performs pattern matching of the pixel data of the c × d first register mark in the memory M58 with respect to the imaging data of the a × b pixel in the memory M53, and the count value N is the first. When the number of pixels d in the vertical direction of the register mark is exceeded (YES in step S335), (X + c-1, Y + d-1) from the (X, Y) address of the imaging data of the a × b pixel in the memory M53. It is determined that the pixel data of the c × d first register mark in the memory M58 is included in the range up to the address. That is, it is determined that the first register mark RM1 is included in the image captured by the WG camera 304.

  If the count value Y exceeds “b−d + 1” in step S327 (FIG. 41) (YES in step S327), it means that the edge of the image data of the WG camera 304 has been exceeded, and the CPU 301 Determines that the first register mark RM1 is not included in the image captured by the WG camera 304, and transmits a signal indicating no first register mark to the drive control device 200 (step S328). Then, upon receiving a signal reception completion signal without the first register mark from the drive control device 200 (YES in step S329), the process returns to step S301 (FIG. 38), and the imaging command for the next WG camera from the drive control device 200 is received. Prepare for.

  When the CPU 301 determines that the first register mark is included in the image captured by the WG camera 304 (FIG. 42: YES in step S335), the CPU 301 reads the count value X in the memory M52 at that time (step S336). The measurement position in the X direction of the first register mark is calculated from the read count value X, and written to the address position in the X direction in the memory M61 (step S337). Then, the reference position in the X direction of the first register mark is read from the address position in the X direction of the memory M62 (step S338), and the reference position in the X direction of the first register mark is determined from the measurement position in the X direction of the first register mark. Subtraction is performed to obtain an X-direction displacement amount Δx1 of the first register mark (see FIG. 53C), and the obtained displacement amount Δx1 of the first register mark in the X direction is written in the X-direction address position of the memory M63. (Step S339).

  The CPU 301 reads the count value Y in the memory M51 at that time (FIG. 43: step S340), calculates the measurement position in the Y direction of the first register mark from the read count value Y, and Y in the memory M61. Write to the address position in the direction (step S341). Then, the reference position in the Y direction of the first register mark is read from the address position in the Y direction of the memory M62 (step S342), and the reference position in the Y direction of the first register mark is determined from the measurement position in the Y direction of the first register mark. Subtraction is performed to obtain the Y-direction displacement amount Δy1 of the first register mark (see FIG. 53C), and the obtained displacement amount Δy1 of the first register mark in the Y-direction is written into the Y-direction address position of the memory M63. (Step S343).

  Then, the CPU 301 transmits the shift amount Δx1 in the X direction and the shift amount Δy1 in the Y direction of the first register mark written in the memory M63 to the drive control device 200 (step S344). Then, upon receipt of the first register mark shift amount reception completion signal from the drive control device 200 (YES in step S345), the first register mark shift amount Δx1 in the X direction to the drive control device 200 and the shift in the Y direction. The transmission of the amount Δy1 is stopped (step S346), and the process returns to step S301 (FIG. 38) to prepare for the next imaging command of the WG camera from the drive control device 200.

[Detection of the position of the first register mark in the drive control unit]
When the CPU 201 of the drive control device 200 receives the shift amount Δx1 in the X direction and the shift amount Δy1 in the Y direction of the first register mark transmitted from the shift amount detection device 300 (FIG. 14: YES in step S117), The received shift amount Δx1 in the X direction and the shift amount Δy1 in the Y direction of the first register mark are written in the memories M9 and M10 (step S118), and a shift amount reception completion signal for the shift amount of the first register mark is transmitted to the shift amount detection device 300. (Step S119).

The CPU 201 sets the count value N of the memory M11 to N = 2 (step S120), reads the reference imaging position PWGr of the WG camera from the memory M8 (step S121), and shifts the first register mark in the Y direction from the memory M10. The amount Δy1 is read (step S122), and the current original imaging position of the WG camera (imaging position of the WG camera) PWG ₁ is obtained from the reference imaging position PWGr of the WG camera and the shift amount Δy1 of the first register mark in the Y direction. The obtained imaging position PWG ₁ of the WG camera is written in the memory M12 (step S123).

Note that the current original imaging position PWG ₁ of the WG camera indicates the timing at which the first register mark is imaged at a reference position such as the center of the imaging data of the WG camera, and the second register mark in the FF camera thereafter. It becomes the reference of the imaging timing.

Further, CPU 201 from the memory M13 read the WG camera -FF camera distance L1 (step S124), the first FF camera than WG camera imaging position PWG ₁ and WG camera -FF inter-camera distance L1 calculated in step S123 obtains an imaging position PFF _1, it writes the image pickup position PFF ₁ of the first FF cameras found in the first address position of the memory M14 (step S125).

FIG. 51 shows the WG camera reference imaging position PWGr, the WG camera reference imaging position PWGr, and the first register mark's Y-direction deviation Δy1 (the WG camera's current original imaging). (Position) PWG ₁ , WG camera imaging position PWG ₁ and FF camera imaging position PFF ₁ obtained from WG camera-FF camera distance L ₁ are shown.

In FIG. 51, PFFr is the reference imaging position of the first FF camera, PIr is the reference printing point arrival position of the first substrate, and the reference imaging position PWGr of the WG camera and the reference imaging position PFFr of the FF camera are The number of printed materials is 4 or more (in this example, approximately 4.3), and the reference imaging position PFFr of the FF camera and the reference print point arrival position PIr of the printed material are the number of printed materials. One or more sheets (in this example, ≈ 1.16 sheets) are separated. PI ₁ is the printing point arrival position of the first substrate # 1, and the printing point arrival position PI ₁ of the first substrate # ₁ will be described later.

The CPU 201 writes the imaging position PFF ₁ of the FF camera in the memory M14 (FIG. 14: step S125), then reads the reference distance M1Lr between the first register marks from the memory M15 (step S126), and the WG obtained in step S123. obtains an imaging position PWG _2NEXT the next WG camera than the reference distance M1Lr between imaging positions PWG ₁ and the first register mark camera, and overwrites the memory M12 (Fig. 15: step S127).

Then, the count value is read from the counter 213 for counting the number of rotations of the printing press (step S128), and the count value is read from the counter 210 for detecting the rotation of the impression cylinder rotation (step S129). The current unwinding length l of the web 4 is obtained from the count value and the count value of the impression cylinder rotation phase detection counter 210 (step S130). Then, the imaging position PWG _2next of the next WG camera is read from the memory M12 (step S131), and it is confirmed whether or not the unwinding length l of the current web 4 has reached the imaging position PWG _2next of the next WG camera. (Step S132).

[Adjustment of initial rough rotation phase of plate cylinder / rubber cylinder (first registration)]
The CPU 201 performs the processing operations in steps S133 (FIG. 16) to S152 (FIG. 18) until it is confirmed in step S132 that the next WG camera has reached the imaging position PWG _2next of the unwinding length l of the web 4. repeat. In the processing of steps S133 to S152, the initial rough rotation phase of the plate cylinder / rubber cylinder is adjusted. The initial rough rotation phase of the plate cylinder / rubber cylinder is adjusted as follows.

The CPU 201 reads the count value from the impression cylinder rotation phase detection counter 210 (FIG. 16: step S133), and obtains the current rotation phase ψ _R of the impression cylinder from the read count value of the impression cylinder rotation phase detection counter 210. (Step S134). Then, the amount of displacement Δy1 in the Y direction of the first register mark is read from the memory M10 (step S135), and the amount of displacement Δy1 in the Y direction of the first register mark is added to the current rotational phase ψ _R of the impression cylinder to correct it. The current rotation phase ψ _R ′ of the impression cylinder is obtained (step S136).

Then, the CPU 201 obtains the rotation phase φm of the plate cylinder / rubber cylinder that should be based on the corrected current rotation phase ψ _R ′ of the impression cylinder (step S137), and counts from the plate cylinder / rubber cylinder rotation phase detection counter 217. Is read (step S138), and the current rotation phase φ _R of the plate cylinder / rubber cylinder is obtained from the read count value of the plate cylinder / rubber cylinder rotation phase detection counter 217 (step S139). Then, the current rotation phase φ _R of the plate cylinder / rubber cylinder is subtracted from the rotation phase φm of the plate cylinder / rubber cylinder obtained in step S137 to obtain the current rotation phase difference Δφ _R of the plate cylinder / rubber cylinder. Then, the current rotational phase difference Δφ _R of the obtained plate cylinder / rubber cylinder is written in the memory M22 (step S140).

Then, CPU 201 obtains the current absolute value of the rotational phase difference [Delta] [phi _R of the current plate cylinder, blanket cylinder from the rotational phase difference [Delta] [phi _R of the plate cylinder, blanket cylinder obtained in step S140 (FIG. 17: Step S141) Then, the first allowable value α1 of the rotational phase difference between the plate cylinder and the rubber cylinder is read from the memory M24 (step S142), and the absolute value of the current rotational phase difference Δφ _R between the plate cylinder and the rubber cylinder is obtained from the plate cylinder and the rubber cylinder. It is confirmed whether or not the rotation phase difference is equal to or smaller than a first allowable value α1 (step S143).

If the absolute value of the current rotational phase difference Δφ _R of the plate cylinder / rubber cylinder is not less than the first allowable value α1 of the rotational phase difference of the plate cylinder / rubber cylinder (NO in step S143), the CPU 201 A correction value conversion table of the current rotational phase difference / rotational speed of the plate cylinder / rubber cylinder is read from the memory M25 (step S144), and the current rotational phase difference Δφ _R of the plate cylinder / rubber cylinder is read from the memory M22 (step S144). S145), a correction value ΔV of the rotational speed is obtained from the current rotational phase difference Δφ _{R of} the plate cylinder / rubber cylinder by using the correction value conversion table of the current rotation phase difference / rotation speed of the plate cylinder / rubber cylinder (step S146). ).

  Then, the CPU 201 reads the rotation speed VPr of the reference plate cylinder / rubber cylinder driving motor from the memory M3 (step S147), and the rotation speed correction value ΔV of the rotation speed VPr of the reference plate cylinder / rubber cylinder driving motor is read. Is added to obtain the corrected rotational speed VPr ′ of the plate cylinder / rubber cylinder drive motor (step S148), and the corrected rotational speed VPr ′ of the plate cylinder / rubber cylinder drive motor is determined as the plate cylinder / rubber cylinder. The signal is output to the drive motor driver 215 via the D / A converter 218 (step S149), the process returns to step S128 (FIG. 15), and the same operation is repeated.

As a result, the rotational speed of the plate cylinder / rubber cylinder driving motor 214 is adjusted, and the absolute value of the current rotational phase difference Δφ _R of the plate cylinder / rubber cylinder is the first allowable value of the rotational phase difference of the plate cylinder / rubber cylinder. The value α1 or less is adjusted.

When the absolute value of the current rotational phase difference Δφ _R between the plate cylinder and the rubber cylinder becomes equal to or less than the first allowable value α1 of the rotational phase difference between the plate cylinder and the rubber cylinder (FIG. 17: YES in step S143), the CPU 201 Then, the rotation speed VPr of the standard plate cylinder / rubber cylinder driving motor is read from the memory M3 (FIG. 18: Step S150), and the read standard rotation speed VPr of the plate cylinder / rubber cylinder driving motor is read from the printing cylinder / rubber. The data is output to the drum drive motor driver 215 via the D / A converter 218 (step S151), and “1” is written in the memory M4 as a value indicating that the correction of the phase deviation by the first register mark is completed (step S151). S152).

The CPU 201 repeats the processing operations in steps S133 to S152 until the unwinding length l of the web 4 reaches the imaging position PWG _2next of the next WG camera. In step S143, the current rotational position of the plate cylinder / rubber cylinder is repeated. If the absolute value of the phase difference Δφ _R is not less than or equal to the first allowable value α1 of the rotational phase difference between the plate cylinder and the rubber cylinder, the process does not proceed to steps S150 to S152. In this case, “2” is still written in the memory M4 as a value indicating that the correction of the phase deviation by the first register mark is not completed.

When the unwinding length l of the web 4 reaches the imaging position PWG _2next of the next WG camera (FIG. 15: YES in step S132), the CPU 201 transmits an imaging command for the WG camera to the deviation amount detection device 300 (FIG. 15). 19: Step S153), and waits for a response from the deviation amount detection device 300 (step S154). The CPU 301 of the deviation amount detection device 300 receives an imaging command of the WG camera from the drive control device 200, images the printed material on the web 4 being conveyed by the WG camera 304, and performs the first register in the same manner as described above. The amount of mark deviation is detected.

  When the CPU 201 of the drive control device 200 receives the shift amount Δx1 in the X direction and the shift amount Δy1 in the Y direction of the first register mark from the shift amount detection device 300 (YES in step S154), the first register mark The X-direction displacement amount Δx1 and the Y-direction displacement amount Δy1 are written in the memories M9 and M10 (step S155), and a displacement amount reception completion signal for the first register mark is transmitted to the displacement amount detection device 300 (step S156).

Then, the CPU 201 reads the WG camera imaging position PWG _2next from the memory M12 (step S157), and reads the first register mark displacement amount Δy1 in the Y direction from the memory M10 (step S158), and WG camera imaging position PWG _2next. Further, the current imaging position (imaging position of the WG camera) PWG ₂ of the WG camera is obtained from the shift amount Δy1 of the first register mark in the Y direction, and the obtained imaging position PWG ₂ of the WG camera is overwritten in the memory M12. (Step S159).

Further, the CPU 201 reads the WG camera-FF camera distance L1 from the memory M13 (step S160), reads the count value N (N = 2) from the memory M11 (step S161), and captures the WG camera image obtained in step S159. position PWG seek ₂ and WG camera -FF camera distance L1 from the imaging position PFF ₂ of the next FF camera, the determined address location of the N-th imaging position PFF ₂ memory M14 of the next FF camera (second) (See FIG. 20: Step S162, FIG. 55 (a)).

Then, read the reference distance M1Lr between the first register mark from the memory M15 (step S163), the reference distance next WG camera imaging than M1Lr between WG camera imaging position PWG ₂ and first register mark obtained in step S159 The position PWG _3next is obtained and overwritten in the memory M12 (step S164), and 1 is added to the count value N of the memory M11 to set N = 3 (step S165).

  Then, the CPU 201 confirms whether or not the count value N is N = 6 (step S166), and repeats the processing operations of steps S128 (FIG. 15) to S166 until N = 6 in step S166.

Thus, in the same manner as described above, the imaging positions PWG _4next , PWG _5next , PWG _{6next of} the next WG camera, and imaging positions PFF ₃ , PFF ₄ , PFF _{5 of} the next FF camera are obtained, and FIG. As shown, the imaging position PFF ₃ of the FF camera is at the third address position of the memory M14, the imaging position PFF ₄ of the FF camera is at the fourth address position, and the imaging position PFF ₅ of the FF camera is at the fifth address position. Going to be written.

  When the CPU 201 confirms that the count value N is N = 6 (YES in step S166), the CPU 201 reads the value written in the memory M4 (step S167), and the value written in the memory M4 is read. It is confirmed whether or not “1” (step S168). If the value written in the memory M4 is not “1” (NO in step S168), the process returns to step S106 (FIG. 12), but if the value written in the memory M4 is “1”. (YES in step S168), it is determined that the phase deviation correction by the first register mark has been completed.

  In this manner, in the present embodiment, the count value is detected after the position of the first register mark RM1 is detected from the first image of the substrate # 1 captured by the WG camera 304 (point t1 shown in FIG. 51). Until N reaches N = 6 (point t2 shown in FIG. 51), the initial coarse rotation phase of the plate cylinder / rubber cylinder is adjusted according to the position of the first register mark RM1 (first registration). Will be done.

Normally, before the count value N reaches N = 3, that is, before the unwinding length l of the web 4 reaches the imaging position PWG _2next of the WG camera, the first registration (plate cylinder / rubber cylinder) The initial coarse rotation phase adjustment) is completed. If the first registration is not completed before reaching the imaging position PWG _2next of the WG camera, the first registration is continued until the count value N reaches N = 6.

In this embodiment, the first registration is continued until the count value N reaches N = 6. As shown in FIG. 52 as a section from the point t1 to the point t2, At the latest, until the unwinding length l of the web 4 reaches the imaging position PFF ₁ of the FF camera, that is, the area including the second register mark RM2 of the first substrate # 1 is captured by the FF camera 305. In the meantime, the first registration may be completed.

[Image capture command of FF camera to deviation detection device from drive control device]
When the CPU 201 determines that the correction of the phase deviation by the first register mark has been completed (FIG. 20: YES in step S168), the count value M in the memory M28 is set to 1 (step S169), and the printing press The count value is read from the counter 213 for counting the number of rotations (FIG. 21: step S170), and the count value is read from the counter 210 for detecting the pressure drum rotation phase (step S171). The unwinding length l of the current web 4 is obtained from the value and the count value of the impression cylinder rotation phase detection counter 210 (step S172). Then, the imaging position PWG _6next of the next WG camera is read from the memory M12 (step S173), and it is confirmed whether or not the unwinding length l of the current web 4 has reached the imaging position PWG _6next of the next WG camera. (Step S174).

In this case, since the current unwinding length l of the web 4 has not yet reached the imaging position PWG _6next of the next WG camera (NO in step S174), the CPU 201 starts FF from the first address position of the memory M14. The camera imaging position PFF ₁ is read (FIG. 22: Step S175), and it is confirmed whether or not the current unwinding length l of the web 4 has reached the imaging position PFF ₁ of the FF camera (Step S176).

Here, if the unwinding length l of the current web 4 has not reached the imaging position PFF ₁ of the FF camera (NO in step S176), the CPU 201 reads the count value M in the memory M28 (FIG. 24: step). S177), it is confirmed whether or not the count value M is “2” (step S178). In this case, since the count value M is “1” (NO in step S178), the process returns to step S170 (FIG. 21), and the processing operations in steps S170 to S178 are repeated.

When the CPU 201 confirms that the unwinding length l of the current web 4 has reached the imaging position PFF ₁ of the FF camera during this processing operation (FIG. 22: YES in step S176), the CPU 201 sends an FF to the deviation amount detection device 300. An imaging command for the camera is transmitted (step S179), and the transmission of the shift amount Δx2 in the X direction and the shift amount Δy2 in the Y direction of the second register mark from the shift amount detection device 300 is awaited (step S180).

[Image capture of printed material by FF camera (detection of deviation of second register mark by deviation detection device)]
When an imaging command for the FF camera is sent from the drive control device 200 (FIG. 44: YES in step S348), the CPU 301 of the deviation amount detection device 300 outputs the imaging command to the FF camera 305 (step S349). Thereby, the FF camera 305 is conveyed at the timing when the imaging command of the FF camera is sent from the drive control device 200, that is, at the timing when the unwinding length l of the web 4 reaches the imaging position PFF of the FF camera. An image of the printing material on the coming web 4 is taken.

  When image data is sent from the FF camera 305 (YES in step S350), the CPU 301 sets the count value Y in the memory M51 to 1 (step S351), and sets the count value X in the memory M52 to 1 (step S352). ), The imaging data of the pixel position specified by the count values X and Y from the FF camera 305 is written in the address position (X, Y) of the memory M64 (step S353).

  Then, the CPU 301 adds 1 to the count value X in the memory M52 (FIG. 45: step S354), reads the number of pixels e in the left-right direction of the FF camera in the memory M65 (step S355), and counts in step S366. The processing operations in steps S353 to S356 are repeated until X exceeds the number of pixels e in the left-right direction of the FF camera.

  If the count value X exceeds the pixel number e in the left-right direction of the FF camera (YES in step S356), 1 is added to the count value Y in the memory M51 (step S357), and the top and bottom of the FF camera in the memory M66. The number of pixels f in the direction is read (step S358), and the processing operations in steps S352 to S359 are repeated until the count value Y exceeds the number of pixels f in the vertical direction of the FF camera in step S359.

  As a result, the imaging data of the e × f pixels from the FF camera 305 is stored in the memory M64. Here, as shown in FIG. 54A, it is assumed that imaging data of an area including the second register mark RM2 of the substrate # 1 is stored in the memory M64 as imaging data of an e × f pixel.

  In the memory M67, as shown in FIG. 54B, g × h pixel data of the second register mark is stored as pattern matching data. The vertical direction of the FF camera 305 is the flow direction of the web 4, and the left-right direction of the FF camera 305 is a direction orthogonal to the flow direction of the web 4.

  When the count value Y exceeds the number of pixels f in the vertical direction of the FF camera (YES in step S359), the CPU 301 sets the count value Y in the memory M51 to 1 (FIG. 46: step S360), and the count value in the memory M52. X is set to 1 (step S361), the count value N in the memory M56 is set to 1 (step S362), and the count value M in the memory M57 is set to 1 (step S363).

  Then, the imaging pixel data of the FF camera at the address position (X + M−1, Y + N−1) in the memory M64 is read (step S364), and the second register mark at the address position (M, N) in the memory M67 is read. The pixel data is read (step S365), and the read image data of the FF camera at the address position (X + M-1, Y + N-1) in the memory M64 and the (M, N) address position in the memory M67 are read. It is confirmed whether or not the pixel data of the two register marks match (see step S366, FIGS. 54A and 54B).

  Here, the imaging pixel data of the FF camera at the address position (X + M−1, Y + N−1) in the memory M64 and the pixel data of the second register mark at the address position (M, N) in the memory M67 are identical. If not (NO in step S366), any pixel data of the imaging data of the FF camera 305 from the address (X, Y) to the address (X + g-1, Y + h-1) at that time is stored in the second register. Unlike the mark pixel data, since there is no second register mark in the range starting from the address (X, Y), the CPU 301 adds 1 to the count value X in the memory M52 (FIG. 47: step S367). ) Read the left-right pixel number e of the FF camera in the memory M65 and the left-right pixel number g of the second register mark in the memory M68 (step) S368, S369), the processing operation of steps S362 to S370 is repeated until the count value X exceeds “eg + 1” in step S370.

During this processing operation, if the count value X exceeds “eg + 1” (YES in step S370), the left and right ends of the image data of the FF camera 305 are exceeded , so the CPU 301 stores the data in the memory M51. 1 is added to the count value Y (step S371), and the vertical pixel number f of the FF camera in the memory M66 and the vertical pixel number h of the second register mark in the memory M69 are read (steps S372 and S373). ), The processing operations of steps S361 to S374 are repeated until the count value Y exceeds “f−h + 1” in step S374.

  During this processing operation, the imaging pixel data of the FF camera at the address position (X + M−1, Y + N−1) in the memory M64 and the pixel data of the second register mark at the address position (M, N) in the memory M67 Are confirmed to match (FIG. 46: YES in step S366), the CPU 301 adds 1 to the count value M in the memory M57 (FIG. 48: step S376), and the second register from the memory M68. The number of pixels g in the left-right direction of the mark is read (step S377), and the processing operations of steps S364 to S378 are repeated until the count value M exceeds the number of pixels g in the left-right direction of the second register mark in step S378.

  When the count value M exceeds the number of pixels g in the left and right direction of the second register mark (YES in step S378), 1 is added to the count value N in the memory M56 (step S379), and the second register mark is registered from the memory M69. The number h of pixels in the vertical direction is read (step S380), and the processing operations in steps S363 to S381 are repeated until the count value N exceeds the number h of pixels in the vertical direction of the second register mark in step S381.

  In this way, the CPU 301 performs pattern matching of the pixel data of the g × h second register mark in the memory M67 with respect to the imaging data of the e × f pixel in the memory M64, and the count value N is the second value. When the number of pixels h in the vertical direction of the register mark is exceeded (YES in step S381), (X + g-1, Y + h-1) from the (X, Y) address of the image data of the e × f pixel in the memory M64. It is determined that the pixel data of the g × h second register mark in the memory M67 is included in the range up to the address. That is, it is determined that the second register mark RM2 is included in the image captured by the FF camera 305.

  If the count value Y exceeds “f−h + 1” in step S374 (FIG. 47) (YES in step S374), it means that the edge of the imaging data of the FF camera 305 has been exceeded, and the CPU 301 Determines that the second register mark is not included in the image captured by the FF camera 305, and displays an error message “No second register mark” on a display (not shown) (step S375).

  When the CPU 301 determines that the second register mark is included in the image captured by the FF camera 305 (YES in step S381), the CPU 301 reads the count value X in the memory M52 at that time (step S382) and reads the read value. The measurement position in the X direction of the second register mark is calculated from the count value X and written in the address position in the X direction in the memory M70 (FIG. 49: Step S383). Then, the reference position in the X direction of the second register mark is read from the address position in the X direction of the memory M71 (step S384), and the reference position in the X direction of the second register mark is determined from the measurement position in the X direction of the second register mark. Subtraction is performed to obtain the amount of deviation Δx2 in the X direction of the second register mark (see FIG. 54C), and the obtained amount of deviation Δx2 in the X direction of the second register mark is written to the address position in the X direction of the memory M72. (Step S385).

  Further, the CPU 301 reads the count value Y in the memory M51 at that time (step S386), calculates the Y-direction measurement position of the second register mark from the read count value Y, and the Y-direction address in the memory M70. The position is written (step S387). Then, the reference position in the Y direction of the second register mark is read from the address position in the Y direction of the memory M71 (FIG. 50: step S388), and the Y direction of the second register mark is measured from the measured position in the Y direction of the second register mark. The reference position is subtracted to determine the amount of deviation Δy2 in the Y direction of the second register mark (see FIG. 54C), and the amount of deviation Δy2 in the Y direction of the second register mark thus obtained is determined as the address in the Y direction of the memory M72. The position is written (step S389).

  Then, the CPU 301 transmits to the drive control device 200 the X-direction displacement amount Δx2 and the Y-direction displacement amount Δy2 of the second register mark written in the memory M72 (step S390). Then, upon receipt of the second register mark shift amount reception completion signal from the drive control device 200 (YES in step S391), the second register mark shift amount Δx2 in the X direction and the Y direction shift to the drive control device 200. The transmission of the amount Δy2 is stopped (step S392), and the process returns to step S301 (FIG. 38) to prepare for the next WG camera imaging command from the drive control device 200.

[Detection of position of second register mark in drive control device (detection of position of previous second register mark)]
When the CPU 201 of the drive control device 200 receives the displacement amount Δx2 in the X direction and the displacement amount Δy2 in the Y direction of the second register mark transmitted from the displacement amount detection device 300 (FIG. 22: YES in step S180), The received X-direction displacement amount Δx2 and Y-direction displacement amount Δy2 of the received second register mark are written in the memories M29 and M30 (step S181), and the displacement amount detection device 300 transmits a displacement amount reception completion signal of the second register mark. (Step S182).

Then, the CPU 201 reads the imaging position PFF ₁ of the FF camera from the first address position of the memory M14 (FIG. 23: step S183), and the shift amount Δy2 in the Y direction between the imaging position PFF ₁ of the FF camera and the second register mark. from seeking the position PM2 ₁ of the second register mark, the position of the second register mark the determined second register a second register mark position before the position PM2 ₁ mark (last detected from FF camera captured image ) PM2 _F is written into the memory M34 (see step S184, FIG. 56A).

Further, CPU 201 is, FF camera is read from the memory M31 - Reads between print point distance L2 (step S185), the second register mark position PM2 ₁ and FF camera obtained in step S184 - the first of the substrate than between print point distance L2 # 1 obtains the print point reaches position PI _1, and writes the determined first print point reaches the position PI ₁ of the substrate # 1 in the first address position of the memory M32 (step S186, FIG. 57 (a) see) . Then, 1 is added to the count value M in the memory M28 to set M = 2, and the process returns to step S170 (FIG. 21).

When the CPU 201 returns to step S170, it goes to step S178 (FIG. 24) through steps S171 to S177, and checks whether or not the count value M in the memory M28 is M = 2. In this case, since the count value M in the memory M28 is set to M = 2 in the previous step S187 (YES in step S178), the CPU 201 reads the count value from the counter 213 for counting the number of rotations of the printing press (step S187). S188), the count value is read from the impression cylinder rotation phase detection counter 210 (step S189), and the current web is calculated from the count value of the counter 213 for counting the number of rotations of the printing press and the count value of the impression cylinder rotation phase detection counter 210. The unwinding length l of 4 is obtained (step S190). Then, the imaging position PFF ₁ of the FF camera is read from the first address position of the memory M14 (step S191), and it is confirmed whether or not the current unwinding length l of the web 4 is at the imaging position PFF ₁ of the FF camera. (Step S192).

[Initial strict rotation phase adjustment of the plate cylinder and rubber cylinder (second registration)]
In step 192, the CPU 201 confirms whether or not it is at the imaging position PFF ₁ of the FF camera with the unwinding length l of the web 4. Here, the CPU 201 has already passed the imaging position PFF ₁ of the FF camera. Therefore, the CPU 201 proceeds to step S193 (FIG. 25) in response to NO in step S192.

In this case, the CPU 201 continues to steps S193 (FIG. 25) to S212 (step S192) until it is confirmed in step S192 that the next FF camera has reached the imaging position PFF ₂ (described later) of the unwinding length l of the web 4. The processing operation of FIG. 27) is repeated. In the processes in steps S193 to S212, the initial strict rotational phase of the plate cylinder and the rubber cylinder is adjusted. The initial precise rotation phase adjustment of the plate cylinder / rubber cylinder is performed as follows.

The CPU 201 reads the count value from the impression cylinder rotation phase detection counter 210 (FIG. 25: Step S193), and obtains the current rotation phase ψ _R of the impression cylinder from the read count value of the impression cylinder rotation phase detection counter 210. (Step S194). Then, the amount of displacement Δy2 of the second register mark in the Y direction is read from the memory M30 (step S195), and the amount of displacement Δy2 of the second register mark in the Y direction is added to the current rotational phase ψ _R of the impression cylinder to correct it. The current rotation phase ψ _R ′ of the impression cylinder is obtained (step S196).

Then, the CPU 201 obtains the rotation phase φm of the plate cylinder / rubber cylinder that should be based on the corrected current rotation phase ψ _R ′ of the impression cylinder (step S197), and the count value from the counter 217 for detecting the plate cylinder / rubber cylinder rotation phase. (Step S198), and the current rotational phase φ _R of the plate cylinder / rubber cylinder is obtained from the count value of the read plate cylinder / rubber cylinder rotation phase detection counter 217 (step S199). Then, the current rotation phase φ _R of the plate cylinder / rubber cylinder is subtracted from the rotation phase φm of the plate cylinder / rubber cylinder obtained in step S197 to obtain the current rotation phase difference Δφ _R of the plate cylinder / rubber cylinder. . The obtained current rotational phase difference Δφ _R of the plate cylinder / rubber cylinder is written into the memory M22 (FIG. 26: step S200).

Then, CPU 201 obtains the current absolute value of the rotational phase difference [Delta] [phi _R of the current plate cylinder, blanket cylinder from the rotational phase difference [Delta] [phi _R of the plate cylinder, blanket cylinder obtained in step S200 (step S201), the memory M33 Then, the second allowable value α2 of the rotational phase difference between the plate cylinder and the rubber cylinder is read (step S202), and the absolute value of the current rotational phase difference Δφ _R between the plate cylinder and the rubber cylinder is the rotational phase difference between the plate cylinder and the rubber cylinder. It is confirmed whether or not it is equal to or smaller than the second allowable value α2 (step S203). In the present embodiment, the second allowable value α2 is smaller than the first allowable value α1 used in the initial coarse rotation phase adjustment (first registration) of the plate cylinder / rubber cylinder (α2 < It is defined as α1).

If the absolute value of the current rotational phase difference Δφ _R of the plate cylinder / rubber cylinder is not less than or equal to the second allowable value α2 of the rotational phase difference of the plate cylinder / rubber cylinder (NO in step S203), the CPU 201 The correction value conversion table of the current rotational phase difference / rotational speed of the plate cylinder / rubber cylinder is read from the memory M25 (step S204), and the current rotational phase difference Δφ _R of the plate cylinder / rubber cylinder is read from the memory M22 (step S204). S205), a correction value ΔV for the rotation speed is obtained from the current rotation phase difference Δφ _{R of} the plate cylinder / rubber cylinder using the current rotation phase difference / rotation speed correction value conversion table of the plate cylinder / rubber cylinder (step S206). ).

  The CPU 201 reads the rotation speed VPr of the reference plate cylinder / rubber cylinder driving motor from the memory M3 (step S207), and the rotation speed correction value ΔV of the rotation speed VPr of the reference plate cylinder / rubber cylinder driving motor is read. Is added to obtain the corrected rotational speed VPr ′ of the plate cylinder / rubber cylinder driving motor (step S208), and the corrected rotational speed VPr ′ of the plate cylinder / rubber cylinder driving motor is determined as the printing cylinder / rubber cylinder. It outputs to the drive motor driver 215 via the D / A converter 218 (step S209), returns to step S170 (FIG. 21), and repeats the same operation.

As a result, the rotational speed of the plate cylinder / rubber cylinder driving motor 214 is adjusted, and the absolute value of the current rotational phase difference Δφ _R of the plate cylinder / rubber cylinder is the second tolerance of the rotational phase difference of the plate cylinder / rubber cylinder. The value α2 or less is adjusted.

When the absolute value of the current rotational phase difference Δφ _R of the plate cylinder / rubber cylinder becomes equal to or smaller than the second allowable value α2 of the rotational phase difference of the plate cylinder / rubber cylinder (FIG. 26: YES in step S203), the CPU 201 Then, the rotation speed VPr of the standard plate cylinder / rubber cylinder driving motor is read from the memory M3 (FIG. 27: Step S210), and the read standard rotation speed VPr of the plate cylinder / rubber cylinder driving motor is read as the printing cylinder / rubber. The data is output to the drum drive motor driver 215 via the D / A converter 218 (step S211), and “1” is written in the memory M5 as a value indicating that the correction of the phase deviation by the second register mark is completed (step S211). S212).

CPU201 until unwinding length l of the web 4 has reached the imaging position PFF ₂ of FF camera, but repeats the processing operation in steps S193～S212, the current rotational phase difference Δφ of the plate cylinder, blanket cylinder in step S203 _If the absolute value of _R does not fall below the second allowable value α2 of the rotational phase difference between the plate cylinder and the rubber cylinder, the process does not proceed to steps S210 to S212. In this case, “2” is still written in the memory M5 as a value indicating that the correction of the phase deviation by the second register mark is not completed.

The CPU 201 repeats the processing operations of steps S193 to S212 while returning to step S170 (FIG. 21). During this processing operation, the unwinding length l of the web 4 reaches the imaging position PWG _6next of the next WG camera. If this is confirmed (YES in step S174), an imaging command of the WG camera is transmitted to the deviation amount detection device 300 (FIG. 28: step S213), and a response from the deviation amount detection device 300 is awaited (step S214). The CPU 301 of the deviation amount detection apparatus 300 receives an imaging command of the WG camera from the drive control apparatus 200, images the printed material on the web 4 being conveyed by the WG camera 304, and performs the first register in the same manner as described above. The amount of mark deviation is detected.

  When the CPU 201 of the drive control device 200 receives the shift amount Δx1 in the X direction and the shift amount Δy1 in the Y direction of the first register mark from the shift amount detection device 300 (YES in step S214), the first register mark The X-direction displacement amount Δx1 and the Y-direction displacement amount Δy1 are written in the memories M9 and M10 (step S215), and a displacement amount reception completion signal for the first register mark is transmitted to the displacement amount detection device 300 (step S216).

Then, the CPU 201 reads the WG camera image pickup position PWG _6next from the memory M12 (step S217), and reads the first register mark displacement amount Δy1 in the Y direction from the memory M10 (step S218), and WG camera image pickup position PWG _6next. Also, the current original image pickup position (image pickup position of the WG camera) PWG ₆ of the WG camera is obtained from the shift amount Δy1 of the first register mark in the Y direction, and the obtained image pickup position PWG ₆ of the WG camera is overwritten in the memory M12. (Step S219).

Note that the current original imaging position PWG ₆ of the WG camera indicates the timing at which the first register mark is imaged at a reference position such as the center of the imaging data of the WG camera, and the second register mark in the FF camera thereafter. It becomes the reference of the imaging timing.

Further, CPU 201 from the memory M13 read the WG camera -FF camera distance L1 (step S220), from the WG camera imaging position PWG ₆ and WG camera -FF inter-camera distance L1 calculated in step S219 of the next FF camera obtains an imaging position PFF _6, it writes the image pickup position PFF ₆ of the determined next FF camera as the imaging position of the latest FF camera memory M40 (step S221).

Then, read the reference distance M1Lr between the first register mark from the memory M15 (Fig. 29: step S222), the next WG than the reference distance M1Lr between WG imaging position of the camera PWG ₆ and the first register mark obtained in step S221 The imaging position PWG _{7next of the} camera is obtained and overwritten in the memory M12 (step S223).

Then, the count value K in the memory M41 is set to K = 2 (step S224), and the imaging position PFF ₂ (see FIG. 55B) of the second FF camera is read from the K = 2th address position in the memory M14. overwrites the imaging position PFF ₂ of the read second FF camera K-1 = 1 th address position (step S225).

Then, 1 is added to the count value K in the memory M41 to set K = 3 (step S226), and the processing of steps S225 to S227 is repeated until the count value K becomes K = 6 in step S227. As a result, as shown in FIG. 55C, the imaging positions PFF _{2 to} PFF ₅ of the FF camera in the memory M14 are shifted laterally and written to the first to fourth address positions.

CPU201 When the count value K is K = 6 (YES in step S227), reads the imaging position PFF ₆ of the latest FF camera written in the memory M40, the imaging position of the read latest FF camera PFF ₆ Is written in the fifth address position in the memory M14 (see step S228, FIG. 55 (d)). Then, 1 is added to the count value N in the memory M11 to set N = 7 (step S229), the process returns to step S170 (FIG. 21), steps S170 to S174, S175 to S178 (FIGS. 22 and 24), and S188. Through S191, the process proceeds to step S192, and the processing operations of steps S193 (FIG. 25) to S212 (FIGS. 26 and 27) are continued. In this case, in step S191 (FIG. 24), the imaging position PFF ₂ (see FIG. 55 (d)) of the FF camera written in the first address position of the memory 14 is read.

CPU201 during this processing operation, when the length l unwinding of the web 4 to confirm that it has reached the imaging position PFF ₂ of FF camera (Figure 24: YES in step S192), the value written in the memory M5 Reading (step S230), it is confirmed whether or not the value written in the memory M5 is “1” (step S231). If the value written in the memory M5 is not “1” (NO in step S231), the process returns to step S106 (FIG. 12), but if the value written in the memory M5 is “1”. (YES in step S231), it is determined that the phase deviation correction by the second register mark has been completed.

In this way, in the present embodiment, after the position of the second register mark RM2 is detected from the image of the first object to be printed # 1 imaged by the FF camera 305 (point t3 shown in FIG. 51), the web 4 (t4 points shown in FIG. 51), exact rotation of the initial plate cylinder, blanket cylinder in accordance with the position of the second register mark RM2 until unwinding length l reaches the imaging position PFF ₂ of FF camera Phase adjustment (second registration) is performed.

In this embodiment, the second registration is performed until the unwinding length l of the web 4 reaches the imaging position PFF ₂ of the FF camera (strict initial phase adjustment of the plate cylinder / rubber cylinder). However, as shown in FIG. 52 as a section from the point t2 to the point t3, the unwinding length l of the web 4 is at the printing point arrival position PI ₁ of the first substrate # 1 at the latest. In the meantime, the second registration may be completed.

[Image capture command of next FF camera to deviation detection device from drive control device]
When the CPU 201 determines that the correction of the phase deviation by the second register mark is complete (YES in step S231), the CPU 201 transmits an imaging command for the FF camera to the deviation amount detection device 300 (FIG. 30: step S232). ), And waits for transmission of the second register mark displacement amount Δx2 in the X direction and the displacement amount Δy2 in the Y direction from the displacement amount detection device 300 (step S233). The CPU 301 of the deviation amount detection device 300 receives an imaging command of the FF camera from the drive control device 200, images the printed material on the web 4 being conveyed by the FF camera 305, and performs the second register in the same manner as described above. The amount of mark deviation is detected.

[Detection of the position of the next second register mark in the drive control device (detection of the position of the subsequent second register mark)]
When the CPU 201 of the drive control device 200 receives the displacement amount Δx2 in the X direction and the displacement amount Δy2 in the Y direction of the second register mark transmitted from the displacement amount detection device 300 (YES in step S233), the received first The shift amount Δx2 in the X direction and the shift amount Δy2 in the Y direction of the two register marks are written in the memories M29 and M30 (step S234), and a shift amount reception completion signal for the second register mark is transmitted to the shift amount detection device 300 (step S234). S235).

Then, CPU 201 reads the image pickup position PFF ₂ of FF camera than the first address position of the memory M14 (step S236), from the Y direction deviation amount Δy2 of the imaging position PFF ₂ and a second register mark FF second camera obtain the position PM2 ₂ registers mark, the determined second position of the second register mark in the rear position PM2 ₂ register mark (FF camera second register mark position of the current detected from the captured image) PM2 _R (See step S237, FIG. 56B)).

[Calculation of expansion / contraction ratio η between second register marks up to FF camera]
Then, the CPU 201 reads the position PM2 _F (PM2 ₁ ) of the previous second register mark from the memory M34 (step S238), and the previous position from the position PM2 _R (PM2 ₂ ) of the second register mark obtained in step S237. The second register mark position PM2 _F (PM2 ₁ ) is subtracted to obtain the second register mark distance M2L _1, and the obtained second register mark distance M2L ₁ is written to the first address position of the memory M36. (Step S239: See FIG. 58 (a)).

Then, CPU 201 reads the reference distance M2Lr between the second register mark from the memory M37 (Fig. 31: step S240), the between the second register mark distance M2L ₁ obtained in step S239 by dividing the reference distance M2Lr, FF camera The expansion / contraction ratio η (η = M2L ₁ / M2Lr) between the second register marks is calculated and written in the memory M38 (step S241).

[Calculation of rotational speed VPc of plate cylinder / rubber cylinder driving motor between second register marks]
Next, the CPU 201 reads the rotation speed VPr of the reference plate cylinder / rubber cylinder driving motor from the memory M3 (step S242), and obtains the rotation speed VPr of the reference plate cylinder / rubber cylinder driving motor in step S241. The reciprocal of the expansion / contraction ratio η between the second register marks up to the FF camera is multiplied to obtain the rotational speed VPc (VPc = VPr × 1 / η) of the plate cylinder / rubber cylinder driving motor between the second register marks, and the memory Write to M39 (step S243).

Then, the CPU 201 reads the second register mark position PM2 _R (PM2 ₂ ) from the memory M35 (step S244), and reads the FF camera-printing point distance L2 from the memory M31 (step S245). The printing point arrival position PI ₂ of the next substrate # 2 is obtained from the position PM2 _R (PM2 ₂ ) of the two register marks and the FF camera-printing point distance L2, and the printing point arrival of the next substrate # 2 thus obtained is obtained. The position PI ₂ is written into the second address position of the memory M32 (see step S246, FIG. 57 (b)). Then, 1 is added to the count value M in the memory M28 to set M = 3 (step S247), and the process proceeds to step S248 (FIG. 32).

[Adjustment of rotation speed of printing cylinder and rubber cylinder during printing]
The CPU 201 reads the count value from the counter 213 for counting the number of rotations of the printing press (step S248), and also reads the count value from the counter 210 for detecting the pressure drum rotation phase (step S249). And the count value of the impression cylinder rotation phase detection counter 210 are used to determine the current web 4 unwinding length l (step S250).

Then, CPU 201 reads the image pickup position PWG _7NEXT of WG camera from the memory M12 (step S251), the unwinding length l of the current web 4 checks whether it has reached the imaging position PWG _7NEXT of WG camera ( Step S252). Further, it reads the imaging position PFF ₂ of FF camera than the first address position of the memory M14 (step S253), whether or not the unwinding length l of the current web 4 has reached the imaging position PFF ₂ of FF camera Confirmation is made (step S254). Further, the printing point arrival position PI ₁ of the substrate is read from the first address position of the memory M32 (step S255), and the unwinding length l of the current web 4 becomes the printing point arrival position PI ₁ of the next substrate. It is confirmed whether or not it has been reached (step S256).

[Achieving the print point arrival position]
In this example, the unwinding length l of the current web 4 has already passed the imaging position PFF ₂ of the FF camera, and the printing point arrival position PI ₁ <the imaging position PWG _7next of the WG camera (see FIG. 51). ).

Therefore, when the CPU 201 confirms that the unwinding length l of the web 4 has reached the printing point arrival position PI ₁ (YES in step S256), that is, the arrival of the first substrate # 1 to the printing point I is reached. Upon confirmation, the rotational speed VPc of the plate cylinder / rubber cylinder drive motor between the second register marks is read from the memory M39 (FIG. 33: Step S257), and the plate cylinder / rubber cylinder drive between the read second register marks is read. The motor rotation speed VPc is output to the plate cylinder / rubber cylinder driving motor driver 215 via the D / A converter 218 (step S258), and the process returns to step S248 (FIG. 32).

In this case, the rotational speed VPc of the plate cylinder / rubber cylinder driving motor between the second register marks is obtained as VPc = VPr × 1 / η in the previous step S243 (FIG. 31), and η is the previous step. Since it is obtained as η = M2L ₁ / M2Lr in S241 (FIG. 31), it corresponds to the expansion / contraction rate η obtained from the distance M2L ₁ between the first second register marks, that is, the FF of the first substrate # 1. The rotational speed of the plate cylinder / rubber cylinder driving motor is adjusted according to the expansion / contraction ratio η up to the camera.

[Arrival to the imaging position of the WG camera]
When the CPU 201 _confirms that the unwinding length l of the web 4 has reached the imaging position PWG _7next of the WG camera (FIG. 32: YES in step S252), the CPU 201 transmits an imaging command of the WG camera to the deviation amount detection device 300. (FIG. 34: Step S259). Then, when the deviation amount Δx1 in the X direction and the deviation amount Δy1 in the Y direction of the first register mark of the printed material imaged from the deviation amount detection device 300 are transmitted (YES in step S260), the first register mark The X-direction displacement amount Δx1 and the Y-direction displacement amount Δy1 are written in the memories M9 and M10 (step S261), and a displacement amount reception completion signal for the first register mark is transmitted to the displacement amount detection device 300 (step S262).

Then, the CPU 201 reads the WG camera imaging position PWG _7next from the memory M12 (step S263), and reads the Y-direction shift amount Δy1 of the first register mark from the memory M10 (step S264), and WG camera imaging position PWG _7next. Further, the current imaging position (imaging position of the WG camera) PWG ₇ of the WG camera is obtained from the shift amount Δy1 of the first register mark in the Y direction, and the obtained imaging position PWG ₇ of the WG camera is overwritten in the memory M12. (Step S265).

Note that the current original imaging position PWG ₇ of the WG camera indicates the timing at which the first register mark is imaged at a reference position such as the center of the imaging data of the WG camera, and the second register mark in the FF camera thereafter. It becomes the reference of the imaging timing.

Further, CPU 201 from the memory M13 read the WG camera -FF camera distance L1 (step S266), from the WG camera imaging position PWG ₇ and WG camera -FF inter-camera distance L1 calculated in step S265 of the next FF camera obtains an imaging position PFF _7, writes the image pickup position PFF ₇ of the determined next FF camera as the imaging position of the latest FF camera memory M40 (Fig. 35: step S 267).

Then, read the reference distance M1Lr between the first register mark from the memory M15 (step S268), the reference distance next WG camera imaging than M1Lr between WG camera imaging position PWG ₇ and the first register mark obtained in step S265 The position PWG _8next is obtained and overwritten in the memory M12 (step S269).

Then, the CPU 201 sets the count value K in the memory M41 to K = 2 (step S227), and the imaging position PFF ₃ of the second FF camera from the second address position of the memory M14 (see FIG. 55D). ) reads, overwrites the image pickup position PFF ₃ of the read second FF camera K-1 = 1 th address position (step S271).

Then, 1 is added to the count value K in the memory M41 to set K = 3 (step S272), and the processing of steps S271 to S273 is repeated until the count value K becomes K = 6 in step S273. Thus, as shown in FIG. 55 (e), the imaging position PFF ₃ ~PFF ₆ of FF camera in the memory M14 is shifted laterally, are written to the 1-4-th address location.

When the count value K becomes K = 6 (YES in step S273), the CPU 201 reads the latest imaging position PFF ₇ of the FF camera written in the memory M40, and reads the latest imaging position PFF ₇ of the FF camera. Is written in the fifth address position of the memory M14 (see step S274, FIG. 55 (f)). Then, 1 is added to the count value N in the memory M11 to set N = 8 (step S275), and the process returns to step S248 (FIG. 32).

[Arrival to the imaging position of the FF camera]
When the CPU 201 confirms that the unwinding length l of the web 4 has reached the imaging position PFF ₃ of the FF camera (FIG. 32: YES in step S254), the CPU 201 transmits an imaging command of the FF camera to the deviation amount detection device 300. (FIG. 36: Step S276). Then, when the shift amount Δx2 in the X direction and the shift amount Δy2 in the Y direction of the second register mark of the imaged printing material from the shift amount detection device 300 are received (YES in step S277), the received second register mark is received. The X-direction displacement amount Δx2 and the Y-direction displacement amount Δy2 are written in the memories M29 and M30 (step S278), and a displacement amount reception completion signal for the second register mark is transmitted to the displacement amount detection device 300 (step S279).

[Detection of the position of the next second register mark (detection of the position of the next second register mark)]
Then, the CPU 201 reads the position PM2 _R (PM2 ₂ ) (see FIG. 56B) of the second register mark after being written in the memory M35, and reads the position PM2 of the previous second register mark into the memory M34. Write as _F (step S280, see FIG. 56C). Then, the imaging position PFF _{3 of the} FF camera (see FIG. 55F) is read from the first address position of the memory M14 (step S281), and the imaging position PFF ₃ of the FF camera and the second register mark are shifted in the Y direction. The current second register mark position PM2 ₃ is obtained from the amount Δy2, and the obtained second register mark position PM2 ₃ is written in the memory M35 as the subsequent second register mark position PM2 _R (step S282, FIG. 56). d)))).

[Calculation of expansion / contraction ratio η between the second register marks up to the FF camera]
Then, the CPU 201 reads the position PM2 _F (PM2 ₂ ) of the previous second register mark from the memory M34 (step S283), and moves forward from the position PM2 _R (PM2 ₃ ) of the second register mark obtained in step S282. The second register mark position PM2 _F (PM2 ₂ ) is subtracted to obtain the next second register mark distance M2L ₂ , and the next second register mark distance M2L ₂ is obtained as the second register mark distance M2L ₂ in the memory M36. Write to the address position (see FIG. 37: Step S284, FIG. 58 (b)).

Then, CPU 201 reads the reference distance M2Lr between the second register mark from the memory M37 (step S285), the second register mark distance M2L ₂ obtained in step S284 by dividing the reference distance M2Lr, next to FF camera The expansion / contraction ratio η (η = M2L ₂ / M2Lr) between the second register marks is obtained and written in the memory M38 (step S286).

[Calculation of Rotational Speed VPc of Plate Cylinder / Rubber Cylinder Driving Motor Between Next Second Register Marks]
Next, the CPU 201 reads the rotation speed VPr of the reference plate cylinder / rubber cylinder driving motor from the memory M3 (step S287) and obtains the rotation speed VPr of the reference plate cylinder / rubber cylinder driving motor in step S286. Multiplying the reciprocal of the expansion / contraction ratio η between the next second register marks up to the FF camera, the rotational speed VPc of the plate cylinder / rubber cylinder driving motor between the next second register marks (VPc = VPr × 1 / η) And is written in the memory M39 (step S288).

Then, the CPU 201 reads the print point arrival position PI ₂ (see FIG. 57B) written in the second address position of the memory M32 and writes it in the first address position of the memory M32 (step S289, FIG. 57 (c)). Then, the second register mark position PM2 _R (PM2 ₃ ) is read from the memory M35 (step S290), the FF camera-printing point distance L2 is read from the memory M31 (step S291), and the second second register mark is read. position PM2 _R (PM2 ₃₎ and FF camera - seeking printing point arrival position PI3 the next printing medium # 3 from the printing point distance L2, the determined next printing point arrival position PI ₃ of the substrate # 3 Write to the second address position of the memory M32 (see step S292, FIG. 57 (d)), and return to step S248 (FIG. 32).

In this embodiment, the unwinding length l of the web 4 reaches the reference imaging position PWGr of the WG camera, as shown in FIG. 51, and then PWG _2next → PWG _3next → PWG _4next → PWG _5next → PFF _{1 → PWG 6next → PFF 2 → PI} 1 → PWG 7next → PFF3 → PI 2 ···· its position so that it is to change. That is, after reaching the imaging position PFF ₂ of the FF camera, the position change of PI → PWG → PFF → PI is repeated. For this reason, in the flowchart shown in FIG. 32, every time the unwinding length l of the web 4 reaches the position confirmed in that step in the order of steps S256, S252, and S254, the same processing operation as described above is performed.

The position of the second register mark RM2 detected from the image of the first object to be printed # 1 imaged by the FF camera 305 before reaching the contact point (printing point) I between 2 and the impression cylinder 3 Accordingly, the rotation phase of the plate cylinder / rubber cylinder is adjusted (strict initial rotation phase adjustment is performed), and the initial rotation phase of the plate cylinder / rubber cylinder is adjusted smoothly so that each substrate is printed. It becomes possible to accurately print the electronic circuit (second circuit) on (first circuit).

In the present embodiment, as shown in FIG. 51, VPc = VPr × 1 / η obtained from the expansion rate η of the first substrate # 1 obtained between PFF ₁ and PFF ₂ is the first. VPc = used as the rotational speed VPc of the plate cylinder / rubber cylinder driving motor during printing of the substrate # 1 and obtained from the expansion rate η of the next substrate # 2 obtained between PFF ₂ and PFF ₃ = The expansion / contraction ratio of the printing material up to the FF camera is about to be printed, such that VPr × 1 / η is used as the rotational speed VPc of the plate cylinder / rubber cylinder driving motor during printing of the next printing material # 2.
