Description

  According to the present invention, each section of the belt-shaped body made of the base material that is easily stretched and processed in the pretreatment process is used as a printed material, and a printing cylinder and a printing cylinder are provided on each printed material conveyed by the belt-shaped material. 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.

  Moreover, in the printing which prints the electronic circuit mentioned above on a base material, each area divided | segmented for every sheet | seat of a strip | belt-shaped body is made into a to-be-printed material (1st circuit), and this strip | belt-shaped body is the conveyance direction (top-bottom direction). Although the belt is transported in a stretched state, the belt is meandering during transportation because the belt is not firmly fixed with a nail or the like, and the circuit printed the second time is printed at the first time. There was a problem that the circuit did not overlap exactly.

  The present invention has been made to solve such a problem, and the object of the present invention is to provide a circuit printed for the first time regardless of the degree of expansion / contraction of the base material or the meandering of the belt-like body being conveyed. It is an object of the present invention to provide an electronic circuit printing method and apparatus capable of accurately aligning a position of a printed circuit and a circuit printed a second time.

  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 reference mark adding step for adding a reference mark to each of the substrates in a pre-processing step; A reference mark area imaging step of imaging an area including the reference mark of the printed material by an imaging means provided in the middle of the conveyance path of the printed material to the contact point between the printing cylinder and the counter cylinder; and a reference mark area imaging step The reference mark position detecting step for detecting the position of the reference mark from the image of the printed material imaged in step (2) and the direction perpendicular to the conveyance direction of the printed material as the left-right direction, and the reference mark detected in the reference mark position detecting step In accordance with the left-right direction deviation amount calculating step for obtaining the amount of deviation in the left-right direction from the reference mark detected last time from the position, and the left-right direction deviation amount between the reference marks obtained in the left-right direction deviation amount calculating step, A horizontal position adjustment step of continuously adjusting the horizontal position of the printing cylinder during printing of the substrate between the reference marks.

  In the present invention, for example, when a belt-shaped body made of a base material that easily stretches is used as a film, and the first circuit is printed in each section divided for each sheet of the film, The circuit is printed a second time on the contact point between the printing cylinder and the counter cylinder on the first circuit (printed material) printed in the section. In the present invention, the first reference mark is added to the substrate in the pretreatment step before the second circuit printing.

  In the present invention, the substrate to which the reference mark is added is conveyed to the contact point between the printing cylinder and the counter cylinder. An area including a fiducial mark of the printed material in the image pickup means provided in the middle of the conveying path to the contact point between the printing cylinder and the counter cylinder during conveyance of the printed material to the contact point between the printing cylinder and the counter cylinder Is imaged. Then, the position of the reference mark is detected from the image of the printed material imaged by the imaging means, and the left-right direction (the conveyance direction of the printed material (from the detected reference mark position) to the previously detected reference mark. The amount of deviation in the direction perpendicular to the vertical direction) is determined, and the position of the printing cylinder in the horizontal direction during printing of the substrate between the reference marks is determined according to the calculated amount of horizontal deviation between the reference marks. Is continuously adjusted.

  Thus, according to the present invention, the position of the printing cylinder in the left-right direction is continuously adjusted during printing of the printing material between the reference marks according to the amount of relative displacement between the reference marks in the left-right direction. Thus, the lateral displacement between the reference marks caused by stretching or meandering is corrected, and each substrate (first circuit) is printed regardless of the degree of expansion and contraction of the base material or the meandering of the belt-like body being conveyed. It is possible to cause the electronic circuit (second circuit) to be printed on the printer so as to overlap accurately.

  According to the present invention, a fiducial mark is added to each of the printed materials, and an imaging unit is provided in the middle of the conveyance path of the printed material to the contact point between the printing cylinder and the counter cylinder, and the imaging unit uses the imaging unit. An area including the fiducial mark is imaged, and the position of the fiducial mark is detected from the image of the substrate imaged by the image pickup means. The position of the fiducial mark detected last time is detected from the detected fiducial mark position. The amount of deviation in the left-right direction between the reference marks is determined, and the printing cylinder is printed during printing of the substrate between the reference marks according to the obtained amount of deviation in the left-right direction between the reference marks. Since the position in the left and right direction of the substrate is continuously adjusted, the positional deviation in the left and right direction between the reference marks caused by stretching and meandering is corrected to adjust the degree of expansion and contraction of the base material and the belt shape during conveyance. Obsessed with meandering body Instead, it is possible to print the electronic circuit (second circuit) on each substrate (first circuit) so as to be accurately overlapped.

[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. 13: step S101), calculates the reference impression cylinder drive motor rotational speed VIr from the read printing speed Vs, and calculates the calculated reference. The 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. 14: 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. 15)).

  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).

When the imaging command for the WG camera is sent from the drive control device 200 (FIG. 42: YES in step S401), the CPU 301 of the deviation amount detection device 300 outputs the imaging command to the WG camera 304 (step S402). 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 S403), the CPU 301 sets the count value Y in the memory M51 to 1 (step S404), and sets the count value X in the memory M52 to 1 (step S405). ), The imaging data of the pixel position specified by the count values X and Y from the WG camera 304 is written in the address position (X, Y) of the memory M53 (step S406).

  Then, the CPU 301 adds 1 to the count value X in the memory M52 (FIG. 43: Step S407), reads the number of pixels a in the left-right direction of the WG camera in the memory M54 (Step S408), and counts in Step S409. The processing operations in steps S406 to S409 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 S409), 1 is added to the count value Y in the memory M51 (step S410), and the top and bottom of the WG camera in the memory M55. The number of pixels b in the direction is read (step S411), and the processing operations in steps S405 to S412 are repeated until the count value Y exceeds the number of pixels b in the vertical direction of the WG camera in step S412.

  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. 57 (a), image data of a wide area including the first register mark RM1 of the first substrate # 1 is stored in the memory M53 as image data of a × b pixels. And

  In the memory M58, as shown in FIG. 57B, the c × d pixel data of the first register mark RM1 is stored as data for pattern matching. 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 S413), sets the count value X in the memory M52 to 1 (step S414), and sets the count value N in the memory M56 to 1 (FIG. 44: FIG. 44). In step S415, the count value M in the memory M57 is set to 1 (step S416).

  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 S417), and the first register mark at the address position (M, N) in the memory M58 is read. The pixel data is read (step S418), 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 S419, FIGS. 57A and 57B).

  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 S419), 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. 45: step S420). ) 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). S421, S422), in step S423 until the count value X exceeds "a-c + 1", and repeats the processing operation in steps S415～S423.

  During this processing operation, if the count value X exceeds “a−c + 1” (YES in step S423), 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 S424), 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 S425 and S426). ), The processing operation of steps S414 to S427 is repeated until the count value Y exceeds “b−d + 1” in step S427.

  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. 44: YES in step S419), the CPU 301 adds 1 to the count value M in the memory M57 (step S430), 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 S431), and the processing operations of steps S417 to S432 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 S432 (FIG. 46).

  When the count value M exceeds the left-right pixel count c of the first register mark (YES in step S432), the CPU 301 adds 1 to the count value N in the memory M56 (step S433), and the first value from the memory M60. The number of pixels d in the vertical direction of the register mark is read (step S434), and the processing operations of steps S416 to S435 are repeated until the count value N exceeds the number of pixels d in the vertical direction of the first register mark in step S435.

  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 S435), the address (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. 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 S427 (FIG. 45) (YES in step S427), 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 without the first register mark to the drive control device 200 (step S428). Then, upon receiving a signal reception completion signal without the first register mark from the drive control device 200 (YES in step S429), the process returns to step S401 (FIG. 42), 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. 46: YES in step S435), the CPU 301 reads the count value X in the memory M52 at that time (step S436). 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 S437). 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 S438), 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 deviation amount Δx1 of the first register mark (see FIG. 57C), and the obtained X-direction deviation amount Δx1 of the first register mark is written to an address position in the X direction of the memory M63. (Step S439).

  The CPU 301 reads the count value Y in the memory M51 at that time (FIG. 47: step S440), 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 S441). 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 S442), 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 determine the amount of displacement Δy1 in the Y direction of the first register mark (see FIG. 57C), and the amount of displacement Δy1 in the Y direction of the first register mark thus determined is written to the address position in the Y direction of the memory M63. (Step S443).

  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 S444). Then, upon receipt of the first register mark shift amount reception completion signal from the drive control device 200 (YES in step S445), the first register mark shift amount Δx1 in the X direction and the Y direction shift to the drive control device 200. The transmission of the amount Δy1 is stopped (step S446), and the process returns to step S401 (FIG. 42) to prepare for the next WG camera imaging command 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 displacement amount Δx1 in the X direction and the displacement amount Δy1 in the Y direction of the first register mark transmitted from the displacement amount detection device 300 (FIG. 15: 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. 55 shows the WG camera's reference imaging position PWGr, the WG camera's reference imaging position PWGr, and the first register mark's Y-direction shift 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. 55, PFFr is the reference image pickup position of the first FF camera, PIr is the reference print point arrival position of the first substrate, and the reference image pickup position PWGr of the WG camera and the reference image pickup 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. 15: Step S125), and 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. 16: 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 of steps S133 (FIG. 17) to S152 (FIG. 19) 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. 17: 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. 18: 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 driving motor driver 215 via the D / A converter 218 (step S149), the process returns to step S128 (FIG. 16), 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 of the plate cylinder / rubber cylinder becomes equal to or less than the first allowable value α1 of the rotational phase difference of the plate cylinder / rubber cylinder (FIG. 18: 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. 19: Step S150), and the read standard rotation speed VPr of the plate cylinder / rubber cylinder driving motor is read. 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. 16: YES in step S132), the CPU 201 transmits an imaging command for the WG camera to the deviation amount detection device 300 (FIG. 16). 20: 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), reads from the memory M10 the Y-direction shift amount Δy1 of the first register mark (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. 21: step S162, FIG. 59 (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. 16) 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. 59 (b) shows. 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. 13), 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.

  Thus, in the present embodiment, the count value is detected after the position of the first register mark RM1 is detected from the image of the first object to be printed # 1 captured by the WG camera 304 (point t1 shown in FIG. 55). Until N reaches N = 6 (point t2 shown in FIG. 55), 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. However, as shown in FIG. 56 as an interval from the point t1 to the point t2, Until the unwinding length l of the web 4 reaches the imaging position PFF ₁ of the FF camera, that is, until the area including the second register mark RM2 of the first substrate # 1 is imaged 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 is complete (FIG. 21: YES in step S168), the CPU 201 sets the count value M in the memory M28 to 1 (step S169), and the printing press. The count value is read from the counter 213 for counting the number of rotations (step S170 in FIG. 22), 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. 23: 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. 25: 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. 22), 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. 23: 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 the imaging command for the FF camera is sent from the drive control device 200 (FIG. 48: YES in step S448), the CPU 301 of the deviation amount detection device 300 outputs the imaging command to the FF camera 305 (step S449). 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 S450), the CPU 301 sets the count value Y in the memory M51 to 1 (step S451), and sets the count value X in the memory M52 to 1 (step S452). ), The imaging data at 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 S453).

  Then, the CPU 301 adds 1 to the count value X in the memory M52 (FIG. 49: Step S454), reads the pixel number e in the horizontal direction of the FF camera in the memory M65 (Step S455), and counts in Step S456. The processing operations in steps S453 to S456 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 number of pixels e in the left-right direction of the FF camera (YES in step S456), 1 is added to the count value Y in the memory M51 (step S457), and the top and bottom of the FF camera in the memory M66 is obtained. The number of pixels f in the direction is read (step S458), and the processing operations in steps S452 to S459 are repeated until the count value Y exceeds the number of pixels f in the vertical direction of the FF camera in step S459.

  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. 58 (a), 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 e × f pixels.

  In the memory M67, as shown in FIG. 58B, g × h pixel data of the second register mark is stored as data for pattern matching. 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 S459), the CPU 301 sets the count value Y in the memory M51 to 1 (FIG. 50: step S460), and the count value in the memory M52. X is set to 1 (step S461), the count value N in the memory M56 is set to 1 (step S462), and the count value M in the memory M57 is set to 1 (step S463).

  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 S464), and the second register mark at the address position (M, N) in the memory M67 is read. The pixel data is read (step S465), 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 coincides (step S466, see FIGS. 58A and 58B).

  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 S466), 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, there is no second 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. 51: step S467). ) Read the horizontal pixel number e of the FF camera in the memory M65 and the horizontal pixel number g of the second register mark in the memory M68 (step). S468, S469), in step S470 until the count value X exceeds "e-g + 1", and repeats the processing operation in steps S462～S470.

  During this processing operation, if the count value X exceeds “eg + 1” (YES in step S470), it means that the left and right ends of the imaging data of the FF camera 305 have been exceeded, so the CPU 301 stores the data in the memory M51. 1 is added to the count value Y (step S471), 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 S472 and S473). ), The processing operations of steps S461 to S474 are repeated until the count value Y exceeds “f−h + 1” in step S474.

  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 (FIG. 50: YES in step S466), the CPU 301 adds 1 to the count value M in the memory M57 (FIG. 52: step S476), and the second register from the memory M68. The number of pixels g in the left-right direction of the mark is read (step S477), and the processing operations in steps S464 to S478 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 S478.

  When the count value M exceeds the number of pixels g in the left-right direction of the second register mark (YES in step S478), 1 is added to the count value N in the memory M56 (step S479), and the second register mark is registered from the memory M69. The number h of pixels in the vertical direction is read (step S480), and the processing operations in steps S463 to S481 are repeated until the count value N exceeds the number h of pixels in the vertical direction of the second register mark in step S481.

  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 S481), the address (X + g-1, Y + h-1) from the (X, Y) address of the imaging 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. 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 S474 (FIG. 51) (YES in step S474), 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 S475).

  When the CPU 301 determines that the second register mark is included in the image captured by the FF camera 305 (YES in step S481), the CPU 301 reads the count value X in the memory M52 at that time (step S482) 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 to the address position in the X direction in the memory M70 (FIG. 53: step S483). Then, the X-direction reference position of the second register mark is read from the X-direction address position of the memory M71 (step S484), and the X-direction reference position of the second register mark is determined from the X-direction measurement position of the second register mark. Subtraction is performed to obtain an X-direction deviation amount Δx2 of the second register mark (see FIG. 58C), and the obtained X-direction deviation amount Δx2 of the second register mark is written in the X-direction address position of the memory M72. (Step S485).

  Further, the CPU 301 reads the count value Y in the memory M51 at that time (step S486), 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 S487). Then, the Y-direction reference position of the second register mark is read from the Y-direction address position of the memory M71 (FIG. 54: step S488), and the Y-direction measurement position of the second register mark is changed to 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. 58C), and the amount of deviation Δy2 in the Y direction of the second register mark thus obtained is used as the address in the Y direction of the memory M72. The position is written (step S489).

  Then, the CPU 301 transmits to the drive control device 200 the amount of displacement Δx2 in the X direction and the amount of displacement Δy2 in the Y direction of the second register mark written in the memory M72 (step S490). Then, upon receipt of the second register mark shift amount reception completion signal from the drive control device 200 (YES in step S491), the second register mark shift amount Δx2 in the X direction to the drive control device 200 and the shift in the Y direction. The transmission of the amount Δy2 is stopped (step S492), and the process returns to step S401 (FIG. 42) 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. 23: 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. 24: step S183), and the deviation amount Δy2 of the imaging position PFF ₁ of the FF camera and the second register mark in the Y direction. from the second register obtains the Y-direction position PM2Y ₁ mark, the determined second register mark Y direction position PM2Y ₁ of the second register mark before the Y-direction position (the last detected from the captured image of the FF camera Y2 position of second register mark) PM2Y _F is written in the memory M31 (see step S184, FIG. 60 (a), FIG. 65). Further, the deviation amount in the X direction of the second register mark from the memory M29 .DELTA.x2 reads (Δx2 _(1)), the read shift amount in the X direction of the second register mark Δx2 (Δx2 ₍₁₎₎ second previous The register mark X position PM2X _F is written in the memory M32 (see step S185, FIG. 61 (a), FIG. 65).

The CPU 201 reads the Y-direction position PM2Y _F (PM2Y ₁ ) of the second register mark before the memory M31 (step S186), reads the FF camera-print point distance L2 from the memory M33 (step S187), The print point arrival position PI ₁ of the first substrate # 1 is obtained from the Y-direction position PM2Y _F (PM2Y ₁ ) of the second register mark and the FF camera-print point distance L2, and the obtained first substrate # 1 is obtained. writing the print point reaches the position PI ₁ of the first address position of the memory M34 (see step S188, FIG. 62 (a)).

Further, the CPU 201 arrives at the print point of the virtual substrate before the first substrate # 1 based on the Y-direction position PM2Y _F (PM2Y ₁ ) of the previous second register mark and the FF camera-print point distance L2. Position (print point arrival position of the virtual substrate) PI ₀ is obtained and written in the memory M35 (step S189). In this example, the printing point arrival position one sheet prior to the printing point arrival position PI ₁ of the first substrate # 1 is obtained as the printing point arrival position PI ₀ of the virtual substrate.

Further, the CPU 201 reads the X-direction shift amount Δx2 (Δx2 ₍₁₎ ) of the second register mark from the memory M29, and uses the read second shift amount Δx2 ₍₁₎ of the second register mark as the first second. The amount of misalignment M2Δx in the X direction between the register marks is written in the memory M36 (see step S190, FIGS. 63A and 65). Then, 1 is added to the count value M in the memory M28 to set M = 2 (step S191), and the process returns to step S170 (FIG. 22).

When the CPU 201 returns to step S170, it goes to step S178 (FIG. 25) 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 S191 (YES in step S178), the CPU 201 reads the count value from the rotation number counter 213 of the printing press (step S192), and the count value is read from the impression cylinder rotation phase detection counter 210 (step S193), and the current web is determined from the count value of the counter 213 for counting the rotation number 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 S194). Then, the printing point arrival position PI ₀ of the virtual substrate in the memory M35 is read (step S195), and whether the current unwinding length l of the web 4 has reached the printing point arrival position PI ₀ of the virtual substrate. It is confirmed whether or not (FIG. 26: step S196).

In this case, the unwinding length l of the web 4 has not yet reached the printing point arrival position PI ₀ of the virtual substrate immediately after the imaging position PFF ₁ of the first FF camera (NO in step S196). ), the routine proceeds to step S203 (FIG. 27) reads the image pickup position PFF ₁ of the FF camera from the first address position of the memory M14.

[Initial strict rotation phase adjustment of the plate cylinder and rubber cylinder (second registration)]
In the next step 204, the CPU 201 checks whether or not the unwinding length l of the web 4 is at the imaging position PFF ₁ of the FF camera. Here, the CPU 201 has already passed the imaging position PFF ₁ of the FF camera. . Therefore, the CPU 201 proceeds to step S205 (FIG. 28) in response to NO in step S204.

In this case, CPU 201, during at step S204 until reaching the imaging position PFF ₂ (described later) of the next FF camera unwinding length l of the web 4 is confirmed, step S205 (FIG. 28) ~S224 ( The processing operation of FIG. 30) is repeated. In the processes of steps S205 to S224, the initial strict rotation 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. 28: step S205), 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 S206). Then, the amount of displacement Δy2 of the second register mark in the Y direction is read from the memory M30 (step S207), 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 S208).

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 S209), and counts from the counter 217 for detecting the plate cylinder / rubber cylinder rotation phase. (Step S210), and the current rotation 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 S211). Then, the current rotational phase φ _R of the plate cylinder / rubber cylinder is subtracted from the rotational phase φm of the plate cylinder / rubber cylinder obtained in step S209 to obtain the current rotational phase difference Δφ _R of the plate cylinder / rubber cylinder. . The obtained rotational phase difference Δφ _R of the plate cylinder / rubber cylinder is written in the memory M22 (step S212).

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 S212 (step S213), the memory M37 Then, the second allowable value α2 of the rotational phase difference between the plate cylinder and the rubber cylinder is read (FIG. 29: Step S214), and the absolute value of the current rotational phase difference Δφ _R between the plate cylinder and the rubber cylinder is It is confirmed whether or not the rotation phase difference is equal to or smaller than a second allowable value α2 (step S215). 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 S215), 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 S216), and the current rotational phase difference Δφ _R of the plate cylinder / rubber cylinder is read from the memory M22 (step S216). S217) Using the current rotational phase difference-rotational speed correction value conversion table of the plate cylinder / rubber cylinder, the rotational speed correction value ΔV is obtained from the current rotational phase difference Δφ _{R of} the plate cylinder / rubber cylinder (step S218). ).

  The CPU 201 reads the reference plate cylinder / rubber cylinder driving motor rotation speed VPr from the memory M3 (step S219), and the reference plate cylinder / rubber cylinder driving motor rotation speed VPr is set to the rotation speed correction value ΔV. Is added to obtain the corrected rotational speed VPr ′ of the plate cylinder / rubber cylinder drive motor (step S220), and the corrected rotational speed VPr ′ of the plate cylinder / rubber cylinder drive motor is determined as the plate cylinder / rubber cylinder. It outputs to the drive motor driver 215 via the D / A converter 218 (step S221), returns to step S170 (FIG. 22), 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 less than the second allowable value α2 of the rotational phase difference of the plate cylinder / rubber cylinder (FIG. 29: YES in step S215), the CPU 201 Then, the rotation speed VPr of the standard plate cylinder / rubber cylinder driving motor is read from the memory M3 (FIG. 30: Step S222), 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 S223), 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 S223). S224).

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 S205～S224, the current rotational phase difference Δφ of the plate cylinder, blanket cylinder in step S215 _If the absolute value of _R is not less than or equal to 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 S222 to S224. 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.

[Adjusting the position of the plate cylinder in the X direction (left and right direction)]
The CPU 201 repeats the processing operations of steps S205 to S224 while returning to step S170 (FIG. 22). During this processing operation, the unwinding length l of the web 4 reaches the printing point arrival position PI ₀ of the virtual substrate. If it is confirmed (FIG. 26: YES in step S196), the rotational speed VIr of the reference impression cylinder driving motor is read from the memory M2 (step S197), and the Y-direction reference distance M2LYr between the second register marks is read from the memory M40. (Step S198), and passes the printing point I of the substrate between the second register marks from the read rotational speed VIr of the reference impression cylinder driving motor and the Y-direction reference distance M2LYr between the second register marks. seek time as a second register mark between transit time t _M2, the transit time t _M2 between the second register mark Write to the memory M46 (step S199).

Then, the CPU 201 reads from the memory M36 the amount of deviation M2Δx (Δx2 ₍₁₎ ) in the X direction between the second register marks (step S200), and steps the amount of deviation M2Δx in the X direction between the read second register marks. The rotation speed VRc of the X-direction registration motor between the second register marks is obtained by dividing by the second register mark passing time t _M2 obtained in S199 (step S201), and between the obtained second register marks. The rotational speed VRc (VRc = M2Δx / t _M2 ) of the X direction registration motor is output to the X direction registration motor driver 219 via the D / A converter 222 (step S202).

As a result, the X-direction registration motor 219 rotates at the rotational speed VRc (VRc = M2Δx / t _M2 ) obtained in step S201, and the X-direction deviation amount M2Δx (Δx2 ₍₁₎ ) between the second register marks. The position of the plate cylinder 1 in the X direction (left-right direction) starts to be continuously adjusted at a moving speed VRc corresponding to the above.

Further, when the CPU 201 confirms that the unwinding length l of the web 4 has reached the imaging position PWG _6next of the next WG camera during this processing operation (FIG. 22: YES in step S174), the deviation amount detection device An imaging command of the WG camera is transmitted to 300 (FIG. 31: step S225), and a response from the deviation detection device 300 is awaited (step S226). 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 S226), 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 S227), and a displacement amount reception completion signal for the first register mark is transmitted to the displacement amount detection device 300 (step S228).

Then, the CPU 201 reads the WG camera imaging position PWG _6next from the memory M12 (step S229), and reads the Y-direction shift amount Δy1 of the first register mark from the memory M10 (step S230), and WG camera imaging 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 S231).

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 S232), from the WG camera imaging position PWG ₆ and WG camera -FF inter-camera distance L1 calculated in step S231 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 M44 (step S233).

Then, read the reference distance M1Lr between the first register mark from the memory M15 (Fig. 32: step S234), the next WG than the reference distance M1Lr between imaging positions PWG ₆ and first register marks of WG camera obtained in step S231 The camera imaging position PWG _7next is obtained and overwritten in the memory M12 (step S235).

Then, the count value K in the memory M45 is set to K = 2 (step S236), and the imaging position PFF ₂ (see FIG. 59B) of the second FF camera is read from the second 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 S237).

Then, 1 is added to the count value K in the memory M45 to set K = 3 (step S238), and the processing of steps S237 to S239 is repeated until the count value K becomes K = 6 in step S239. As a result, as shown in FIG. 59 (c), 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.

When the count value K reaches K = 6 (YES in step S239), the CPU 201 reads the latest imaging position PFF ₆ of the FF camera written in the memory M44, and reads the latest imaging position PFF ₆ of the FF camera. Is written in the fifth address position in the memory M14 (see step S240, FIG. 59 (d)). Then, 1 is added to the count value N in the memory M11 to set N = 7 (step S241), the process returns to step S170 (FIG. 22), steps S170 to S174, S175 to S178 (FIGS. 23 and 25), and S192. Steps S203 and S204 (FIG. 27) are passed through .about.S196 (FIG. 26), and the processing operations of steps S205 (FIG. 28) to S224 (FIG. 29) are continued. In this case, in step S203 (FIG. 27), the imaging position PFF ₂ (see FIG. 59D) 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 27: YES in step S204), the value written in the memory M5 Reading (step S242), it is confirmed whether or not the value written in the memory M5 is “1” (step S243). If the value written in the memory M5 is not “1” (NO in step S243), the process returns to step S106 (FIG. 13), but if the value written in the memory M5 is “1”. (YES in step S243), 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 substrate # 1 captured by the FF camera 305 (point t3 shown in FIG. 55), the web 4 (t4 points shown in FIG. 55), plate cylinder, blanket cylinder in accordance with the position of the second register mark RM2 (Y direction position) until unwinding length l reaches the imaging position PFF ₂ of FF camera In the initial stage, the strict rotation phase adjustment (second registration) is performed.

Further, in the present embodiment, in conjunction with the second registration, from the time when the unwinding length l of the web 4 reaches the printing point arrival position PI ₀ of the virtual substrate, the interval between the second register marks is reached. The position of the plate cylinder 1 in the X direction starts to be continuously adjusted at a moving speed VRc corresponding to the amount of deviation M2Δx (Δx2 ₍₁₎ ) in the X direction. Thus, the displacement of the plate cylinder 1 in the X direction between the second register marks M2Δx until the unwinding length l of the web 4 reaches the printing point arrival position PI ₁ of the first substrate # 1. It moves in the X direction by (Δx2 ₍₁₎ ) (see FIG. 66), and the horizontal position of the plate mounted on the plate cylinder 1 and the horizontal position of the substrate # 1 are accurately matched. .

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. 56 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]
If the CPU 201 determines that the correction of the phase deviation by the second register mark is complete (FIG. 27: YES in step S243), the CPU 201 transmits an imaging command for the FF camera to the deviation amount detection device 300 (FIG. 33). Step S244), waiting for transmission of the displacement amount Δx2 in the X direction and the displacement amount Δy2 in the Y direction of the second register mark from the displacement amount detection device 300 (Step S245). 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)]

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 M42 (step S255).

[Calculation of X-direction Deviation M2Δx Between Second Register Marks]
Further, CPU 201 reads the displacement amount in the X direction of the second register mark from the memory _{M29 Δx2 (Δx2 (2))} , after the shift amount in the X direction of the read second register mark Δx2 _{(Δx2 (2))} Is written in the memory M43 as the X-direction position PM2X _R of the second register mark (see step S256, FIG. 61 (b), FIG. 65).

Then, the X-direction position PM2X _F (Δx2 ₍₁₎ ) of the second register mark before the memory M32 is read (step S257), and the X-direction position PM2X _R (Δx2 ₍ 2) of the second register mark after writing to the memory M43. ₂₎ The X-direction position PM2X _F (Δx2 ₍₁₎ ) of the previous second register mark is subtracted from 2) to obtain the X-direction shift amount M2Δx between the second register marks, and the X-direction between the second register marks Shift amount M2Δx (M2Δx = Δx2 ₍₂₎ −Δx2 ₍₁₎ ) is written in the memory M36 (see step S258, FIG. 63B, FIG. 65).

Then, the CPU 201 reads the Y-direction position PM2Y _R (PM2Y ₂ ) of the subsequent second register mark from the memory M38 (step S259), reads the FF camera-print point distance L2 from the memory M33 (step S260), and The printing point arrival position PI ₂ of the next printing material # ₂ is obtained from the Y-direction position PM2Y _R (PM2Y ₂ ) of the second register mark and the FF camera-printing point distance L2, and the next printing material # ₂ thus obtained is obtained. writing the print point arrival position PI ₂ in the second address position of the memory M34 (see step S261, FIG. 62 (b)). Then, 1 is added to the count value M in the memory M28 to set M = 3 (step S262), and the process proceeds to step S263 (FIG. 35).

[Adjustment of rotational speed of plate cylinder and rubber cylinder during printing and position of plate cylinder in X direction]
The CPU 201 reads the count value from the counter 213 for counting the number of rotations of the printing press (step S263), and also reads the count value from the counter 210 for detecting the pressure drum rotation phase (step S264). And the count value of the impression cylinder rotation phase detection counter 210, the current web 4 unwinding length l is obtained (step S 265).

Then, CPU 201 reads the image pickup position PWG _7NEXT of WG camera from the memory M12 (step S266), the unwinding length l of the current web 4 checks whether it has reached the imaging position PWG _7NEXT of WG camera ( Step S267). Further, it reads the imaging position PFF ₂ of FF camera than the first address position of the memory M14 (step S268), 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 S269). Further, the printing point arrival position PI ₁ of the substrate is read from the first address position of the memory M34 (step S270), 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 S271).

[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. 55). ).

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 S271), 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 M42 (FIG. 36: step S272), and the plate cylinder / rubber cylinder drive between the read second register marks is read. The rotational speed VPc of the motor is output to the plate cylinder / rubber cylinder driving motor driver 215 via the D / A converter 218 (step S273).

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 S255 (FIG. 34), and η is the previous step. Since it is obtained as η = M2LY ₁ / M2LYr in S253 (FIG. 34), it corresponds to the expansion / contraction rate η obtained from the Y-direction distance M2LY ₁ between the first second register marks, that is, the first substrate # 1. The rotational speed of the plate cylinder / rubber cylinder driving motor 214 is adjusted in accordance with the expansion / contraction ratio η up to the FF camera.

Further, CPU 201 reads the rotational speed VIr of the impression cylinder drive motor of the reference from the memory M2 (step S274), reads the Y-direction distance M2LY ₁ between second register mark from the memory M39 (step S275), it this read Based on the rotational speed VIr of the reference impression cylinder driving motor and the Y-direction distance M2LY ₁ between the second register marks, the time required to pass the printing point I of the substrate between the second register marks is the time t between the second register marks. _Obtained as _M2 , and this second register mark passing time t _M2 is written in the memory M46 (step S276).

Then, the CPU 201 reads the amount of displacement M2Δx (Δx2 ₍₂₎ −Δx2 ₍₁₎ ) in the X direction between the second register marks from the memory M36 (step S277), and in the X direction between the read second register marks. The deviation amount M2Δx is divided by the second register mark passage time t _M2 obtained in step S276 to obtain the rotational speed VRc of the X direction registration motor between the second register marks (step S278). The rotational speed VRc (VRc = M2Δx / t _M2 ) of the X direction registration motor between the two register marks is output to the X direction registration motor driver 219 via the D / A converter 222 (step S279). Returning to step S263 (FIG. 35).

As a result, the X-direction registration motor 219 rotates at the rotational speed VRc (VRc = M2Δx / t _M2 ) obtained in step S278, and the displacement amount M2Δx (Δx2 ₍₂₎ − in the X direction between the second register marks _). The position of the plate cylinder 1 in the X direction starts to be continuously adjusted at a moving speed corresponding to Δx2 ₍₁₎ ). That is, from the time when the length l unwinding of the web 4 has reached the print point reaches the position PI ₁ of the substrate # 1, the shift amount in the X direction between the second register mark _{M2Δx (Δx2 (2) -Δx2 (} 1) ), The position of the plate cylinder 1 in the X direction begins to be continuously adjusted.

Thus, until a length l unwinding of the web 4 reaches the printing point arrival position PI ₂ of next printing material # 2, the amount of deviation of the position of the plate cylinder 1 is X direction between the second register mark M2Δx (Δx2 ₍₂₎ −Δx2 ₍₁₎ ) is moved in the X direction (see FIG. 67), and the horizontal position of the plate mounted on the plate cylinder 1 and the horizontal position of the substrate # 2 are accurately determined. It will be matched.

  In addition, printing of the substrate # 1 is started in a state where the position of the plate mounted on the plate cylinder 1 in the left-right direction and the position of the substrate # 1 in the left-right direction are accurately matched, and printing of the substrate # 1 is performed. Among them, since the position of the plate cylinder 1 is continuously moved in the X direction (left and right direction) at the moving speed VRc, the positional deviation generated in the substrate # 1 due to the meandering of the web 4 being conveyed is also corrected. It will be a thing.
