  As the paper W passes between the impression cylinder 117 and the second number cylinder 118, the ink previously transferred from the inking device 119 to the surface of the second number cylinder 118 is transferred to the impression cylinder 117. The second number is printed by being transferred to one surface of the paper W held and conveyed on the peripheral surface.

  The paper W having the second number printed on one surface thereof on the impression cylinder 117 is then transferred to the holding claw device of the transfer cylinder 120 and then transferred to the first drying unit 121. When the leading end side is replaced by the gripping claw device of the cylinder 122, the cylinder 122 is held and conveyed by the conveying cylinder 122 with one surface facing outward.

  Under this transport, the drying lamp 123 heats and dries one side of the paper W that has been subjected to the above-described seal printing and first and second number printing and before being coated by the coating units 126 and 135. Is done.

  Subsequently, the paper W is held on the impression cylinder 127 so that the other side (rear surface) faces outward by replacing the leading end with the gripping claw device of the impression cylinder 127 of the other side coating unit 126. Then transported.

  As the paper W passes between the impression cylinder 127 and the coating cylinder 128, a coating liquid such as varnish previously applied to the surface of the coating cylinder 128 from the anilox roller 129 and the chamber coater 130 is applied to the pressure cylinder 127. It is applied to the other surface of the paper W held and conveyed on the peripheral surface of the cylinder 127 and subjected to a coating process.

  The paper W whose other surface is coated on the impression cylinder 127 is then replaced by the gripping claw device of the conveyance cylinder 131 and conveyed from the conveyance cylinder 131 to the second drying unit 132. When the leading end side is replaced by the gripping claw device of the cylinder 133, the cylinder 133 is held and conveyed by the conveying cylinder 133 with the other surface facing outward.

  Under this conveyance, the other side of the paper W that has been coated on the other side and not coated on the other side is heated and dried by the drying lamp 134.

  Subsequently, the paper W is held on the impression cylinder 136 so that the one side (front surface) is directed outward by replacing the leading end side with the holding claw device of the impression cylinder 136 of the one-side coating unit 135. Then transported.

  As the paper W passes between the impression cylinder 136 and the coating cylinder 137, a coating liquid such as varnish previously applied to the surface of the coating cylinder 137 from the anilox roller 138 and the chamber coater 139 is applied to the pressure cylinder 136. It is applied to one surface of the paper W held and conveyed on the peripheral surface of the cylinder 136 and subjected to a coating process.

  The paper W having one surface coated on the impression cylinder 136 is then replaced by a claw hook (not shown) of the transport chain 142 in the paper discharge device 140 through the delivery cylinder 141, so that this time. Is transported through the upper travel chain portion of the transport chain 142 with the other side facing outward.

  The paper W transported by the transport chain 142 is heated by a drying lamp 145 before being stacked on the stacking bases 143a to 143c in a state of being guided and extended while being attracted to the suction guide 144. Dried.

  Then, the paper W is transported according to the travel of the transport chain 142, and the stacking bases 143a to 143c are arranged so that one surface (front surface) on which the above-described stamp printing and first and second number printing are performed faces upward. It is discharged and loaded on top.

  When the stamp printing, the number printing, and the coating process are performed on the paper W in this manner, for example, if a malfunction occurs in the stamp printing due to some reason, the control device 10 causes the inspection camera for the stamp to be printed. Based on the image signal from 124A, the inspection unit 12 outputs an NG signal for seal printing to the AND circuit 13, and an emergency cylinder removal signal for seal printing is output from the AND circuit 13 to the cylinder movement control unit 14, thereby controlling the cylinder movement. In accordance with the rotational phase of the combination printing machine 100 input from the main control unit 11, the unit 14 performs the stamp printing unit based on the emergency cylinder insertion / unrolling conversion curve (emergency cylinder movement timing: see FIG. 4B). The rotation direction and the rotation speed of the stepping motor 100A for the case / body removal 106 are obtained, and the direction and the rotation speed are supplied to the case / motor removal motor driver 15A. And printing the cylinders 111 and 116 and the coating units 126 and 135 on the basis of a normal cylinder / barrel conversion curve (normal cylinder movement timing: see FIG. 4A). The rotation directions and rotation speeds of the stepping motors 100B to 100E are calculated, and the rotation direction and rotation speed commands are output to the respective cylinder insertion / removal motor drivers 15B to 15E.

  Then, the controller 10 causes the cylinder driving / unrolling motor driver 15 </ b> A to follow the notch portion of the impression cylinder 107 of the stamp printing unit 106, that is, next to the paper W on which a defective seal has been printed. An emergency cylinder insertion / unrolling conversion curve (emergency cylinder movement timing: figure) so that the stamp cylinder 108 is emergency-rolled at the rotational phase of the notch where the gripping device for holding the paper W is provided. 4B), the operation / control of the stepping motor 100A is performed, and the motor drivers 15B to 15E for the case / body removal control the pressures of the printing units 111 and 116 and the coating units 126 and 135. Each of the cylinders 113, 118, 128, and 137 is removed by the rotational phase of the notch portion next (nearest) to the cylinders 112, 117, 127, and 136. , Steady impression throw / off adjustment conversion curve (steady drum moving timing: see FIG. 4A) on the basis of, operating controls each cylinder engagement / off adjustment stepping motor 100B~100E for each.

  Subsequently, in the control device 10, the main control unit 11 controls the operation of the paper feeding device 101 so as to stop the feeding of the paper W, and the paper W in the units 106, 111, 116, 126, 135 is controlled. Are all discharged to the paper discharge device 140, and the operation of the printing press 100 is controlled so that the operation of the combination printing press 100 is stopped.

  Further, for example, when the first number printing has a problem for some reason, the control device 10 determines that the inspection unit 12 performs an AND operation based on the image signal from the first number inspection camera 124B. The first number printing NG signal is output to the circuit 13, the first number printing emergency cylinder removal signal is output from the AND circuit 13 to the cylinder movement control unit 14, and the cylinder movement control unit 14 is connected to the main control unit 11. In accordance with the rotation phase of the combination printing press 100 inputted from the above, the first number printing unit 111 is fed / The rotation direction and rotation speed of the stepping motor 100B for body removal are obtained, the rotation direction and rotation speed commands are output to the motor driver 15B for body removal / body removal, and the normal body insertion / body removal conversion is performed. Rotation direction and rotation of the stepping motors 100A, 100C to 100E for cylinder-insertion / cylinder removal of the printing units 106, 116 and the coating units 126, 135 based on the probe (steady cylinder movement timing: see FIG. 4A). The speed is obtained, and the rotational direction and rotational speed command are output to each of the cylinder driver 15A and 15C-15E.

  Then, the control device 10 causes the cylinder-insertion / unrolling motor driver 15B to perform the next notch portion of the impression cylinder 112 of the first number printing unit 111, that is, the first number printing in which a defect has occurred. An emergency trunking / unrolling conversion curve (emergency unrolling curve) is made so that the number cylinder 113 is urgently unrolled by the rotational phase of the notch portion where the gripping claw device that holds the paper W following the wrapped paper W is provided. Cylinder movement timing: refer to FIG. 4B), the operation of the barreling / boring stepping motor 100B is controlled, and the drumming / boring motor drivers 15A, 15C to 15E are connected to the printing units 106, 116 and The cylinders 108, 118, 128, and 137 are rotated at the rotational phase of the next (closest) notch of the impression cylinders 107, 117, 127, 136 of the coating units 126, 135. Each stepping motor 100A, 100C to 100E is controlled to operate in accordance with a steady case-insertion / case-removal conversion curve (steady case-movement timing: see FIG. 4A). To do.

  Subsequently, the control device 10 controls the operation of the printing press 100 so as to stop the operation of the combination printing press 100 in the same manner as described above.

  Further, for example, when a trouble occurs in the second number printing due to some cause, the control device 10 causes the inspection unit 12 to perform an AND circuit based on a signal from the second number inspection camera 124C. The second number printing NG signal is output to 13, the second number printing emergency cylinder removal signal is output from the AND circuit 13 to the cylinder movement control unit 14, and the cylinder movement control unit 14 is output from the main control unit 11. Depending on the input rotation phase of the combination printing machine 100, based on the urgent cylinder / barrel conversion curve (emergency cylinder movement timing: see FIG. 4B), the cylinder / cylinder of the second number printing unit 116 is used. The rotational direction and rotational speed of the stepping motor 100C for punching are obtained, the rotational direction and rotational speed commands are outputted to the motor driver 15C for trunking / barreling, and the normal casing / barrelless conversion car is output. Based on (steady cylinder movement timing: see FIG. 4A), the rotation direction and rotation of the stepping motors 100A, 100B, 100D, and 100E for the cylinder insertion / unrolling of the printing units 106 and 111 and the coating units 126 and 135 The speeds are respectively obtained, and the rotation direction and rotation speed commands are output to each of the case-in / case-out motor drivers 15A, 15B, 15D, and 15E.

  Then, the controller 10 causes the motor driver 15C for cylinder insertion / unrolling to perform the next notch portion of the impression cylinder 117 of the second number printing unit 116, that is, the second number printing in which a defect has occurred. An emergency trunking / unrolling conversion curve (emergency unrolling curve) so that the numbering cylinder 118 is urgently unrolled at the rotational phase of the notch where the gripper device that holds the paper W following the wrapped sheet W is provided. Cylinder movement timing: refer to FIG. 4B), the cylinder feeding / boring stepping motor 100C is controlled to operate, and the drum loading / boring motor drivers 15A, 15B, 15D, 15E are connected to the printing unit 106, The cylinders 108, 113, 128, 1 are arranged at the rotational phase of the next (nearest) notch of the pressure drums 107, 112, 127, 136 of the coating unit 126, 135. 7 to each of the stepping motors 100A, 100B, 100D, and 100E for barreling / boring, based on a regular barreling / trunking conversion curve (steady barrel movement timing: see FIG. 4A). Control each operation.

  Subsequently, the control device 10 controls the operation of the printing press 100 so as to stop the operation of the combination printing press 100 in the same manner as described above.

  As described above, when the operation of the printing press 100 is stopped, the paper W on which the printing failure has occurred is discarded. For example, if a problem occurs in the seal printing, the paper W printed by the second number printing unit 116 when the problem occurs and the second number printing unit 116 prints before that. The paper W that has been printed (for example, the paper W at least eight sheets before the paper W that has caused printing failure) is ejected in a state in which the seal printing, the first and second number printing, and the coating are all performed satisfactorily. ing.

  On the other hand, when the above problem occurs, the paper W printed by the first number printing unit 111 and the first number printing unit 111 are printed before the paper W and the second number printing unit 116 prints it. The paper W before printing (for example, the paper W four to seven sheets before the paper W in which printing failure has occurred) has been successfully printed with the stamp printing and the first number printing, but the second number printing. The first number is printed by the seal printing unit 106 before the defective printing paper W printed by the seal printing unit 106 when the above-mentioned malfunction occurs. The paper W before being printed by the unit 111 (for example, the paper W which is 1 to 3 sheets before the paper W in which the printing failure has occurred) is printed with a good seal, but the first and second numbers. Not printed or coated It has been discharged in state.

  For this reason, when the above problem occurs, the paper W printed by the first number printing unit 111 and the first number printing unit 111 are printed before the paper W and the second number printing unit 116 prints it. The second number printing and coating are continuously performed on the paper W before being printed (for example, the paper W four to seven sheets before the paper W in which the printing failure has occurred), and a stamp is generated when the above-described problem occurs. The paper W printed by the seal printing unit 106 before being printed by the first number printing unit 111 before the defective paper W printed by the printing unit 106 (for example, from the paper W causing the defective printing). In addition, the first and second number printing and coating are continuously performed on the first to third sheets of paper W), so that these sheets of paper W can be handled as regular sheets.

  Further, for example, when a failure occurs in the first number printing, the paper W printed by the second number printing unit 116 when the failure occurs, and the second number printing unit before that. The paper W printed in 116 (for example, paper W four or more sheets earlier than the paper W in which printing failure occurred) is in a state in which the seal printing, the first and second number printing, and the coating are all performed satisfactorily. The paper is ejected.

  On the other hand, when the above problem occurs, the first number printing unit 111 prints before the defective printing paper W printed by the first number printing unit 111 and the second number printing unit 116 prints it. The paper W before printing (for example, the paper W 1 to 3 papers before the paper W in which printing failure has occurred) is well printed on the stamp and the first number, but the second number printing The paper W is ejected in a state where no coating is applied, and the paper W printed by the seal printing unit 106 when the above-described malfunction occurs, and the first number printing is performed by the stamp printing unit 106 before that. The paper W before being printed by the unit 111 (for example, the paper W that is 1 to 4 sheets after the paper W in which the printing failure has occurred) is printed with a good seal, but the first and second numbers. Not printed or coated It has been discharged in state.

  For this reason, when the above problem occurs, printing is performed by the first number printing unit 111 before the defective printing paper W printed by the first number printing unit 111 and is printed by the second number printing unit 116. The second number printing and coating are continuously applied to the paper W before being printed (for example, the paper W 1 to 3 sheets before the paper W in which the printing failure has occurred), and a stamp is generated when the above-described problem occurs. The paper W printed by the printing unit 106 and the paper W before being printed by the seal printing unit 106 and before being printed by the first number printing unit 111 (for example, from the paper W that has caused printing failure) Further, the first and second number printing and coating are continuously performed on the first to fourth sheets W), so that these sheets W can be handled as regular sheets.

  Further, for example, when a problem occurs in the second number printing, the second number printing unit 116 precedes the paper W printed by the second number printing unit 116 when the problem occurs. The printed paper W (for example, one or more paper W before the paper W in which printing failure has occurred) is ejected in a state in which the seal printing, the first and second number printing, and the coating are all performed satisfactorily. Has been.

  On the other hand, when the above problem occurs, the paper W printed by the first number printing unit 111 and the first number printing unit 111 are printed before the paper W and the second number printing unit 116 prints it. The paper W before printing (for example, the paper W 1 to 4 sheets after the paper W in which printing failure has occurred) is well printed on the stamp and the first number, but the second number printing The paper W is ejected in a state where no coating is applied, and the paper W printed by the seal printing unit 106 when the above-described malfunction occurs, and the first number printing is performed by the stamp printing unit 106 before that. The paper W before being printed by the unit 111 (for example, the paper W that is 5 to 8 sheets after the paper W in which the printing failure has occurred) has been printed well, but the first and second numbers. Not printed or coated It is discharged in the state.

  For this reason, when the above problem occurs, the paper W printed by the first number printing unit 111 and the first number printing unit 111 are printed before the paper W and the second number printing unit 116 prints it. The second number printing and coating are continuously performed on the paper W before being printed (for example, the paper W that is 1 to 4 sheets after the paper W in which the printing failure has occurred), and a stamp is generated when the above-described problem occurs. The paper W printed by the printing unit 106 and the paper W before being printed by the seal printing unit 106 and before being printed by the first number printing unit 111 (for example, from the paper W that has caused printing failure) Further, the first and second number printing and coating are continuously performed on the paper W) after 5 to 8 sheets, so that the paper W can be handled as regular paper.

  As described above, in the combination printing press 100 according to the present embodiment, the seal printing and the first and second number printing are unit-type, and the stamp printing unit 106, the first number printing unit 111, and the second number printing are performed. The number printing unit 116 is connected to each other by a single transfer cylinder (transfer cylinder) 110, 115. The impression cylinders 107, 112, 117 and the cylinders 108, 113, 118 of the printing units 106, 111, 116 are connected to each other. Inspection cameras 124A to 124C are provided so as to face the outer peripheral surfaces of the impression cylinders 107, 112, 117 on the downstream side in the rotation direction of the impression cylinders 107, 112, 117 from the contact positions (printing points) of By inspecting the stamps and numbers printed by the printing units 106, 111, and 116 immediately after printing, it is possible to immediately find out printing defects. Further, immediately after the trouble occurs in the paper W, when each of the cylinders 108, 113, 118 is opposed to the nearest notch of each of the impression cylinders 107, 112, 117, the cylinders 108, 113, 118 are respectively By pulling out and temporarily stopping printing on the next paper W and performing necessary printing on the paper W later, only the paper W in which the printing failure has occurred can be used as the damaged paper.

  Further, in the control device 10, a “steady cylinder insertion (contact movement) signal for performing normal cylinder insertion (contact movement) and cylinder removal (separation movement) at the start of printing operation or when the printing operation is stopped, etc. In addition to the main control unit (sequencer) 11 that outputs a “steady body removal (separation movement) signal” to the body movement control unit (camless control unit) 14, the NG signal of the inspection unit 12 is transmitted to the body movement control unit 14. By providing an AND circuit (emergency drumming output unit) 13 that directly inputs the signal as an emergency drumming signal, the main control unit 11 can eliminate the processing time delay and perform the drumming (separation movement) quickly. At the same time, the body is removed based on the emergency case insertion / body removal conversion curve (emergency case movement timing: see FIG. 4B) different from the normal case insertion / body removal conversion curve (steady case movement timing: see FIG. 4A). Cause problems. It can be performed reliably thrown off in most recent notch of the impression cylinder 107,112,117 immediately was.

Therefore, according to the combination printing machine 100 according to the present embodiment, since only one sheet of paper W can be used as loss paper, the generation amount of loss paper can be suppressed as much as possible and used for securities. It is possible to greatly reduce the waste of expensive paper W that is produced.
And versatility can be improved.
