On the other hand, the ink is transferred to the holding claw device of the impression cylinder 6 and conveyed, while the ink of each ink supply device 11 is transferred to the ink collecting cylinder 9 via each pattern roller 10 and supplied onto the intaglio surface of the intaglio cylinder 8. Is done.

  The surplus ink (hereinafter referred to as surplus ink) supplied onto the intaglio surface of the intaglio cylinder 8 is removed by the wiping roller 19 of the wiping device 21, and the paper 2 is transferred to the impression cylinder 6 and the intaglio cylinder 8. When the paper passes between the two, the ink of the intaglio cylinder 8 is transferred to the paper 2 and printed. After the paper 2 is conveyed by the paper discharge chain 22b of the paper discharge device 22 through the paper discharge cylinder 27, the paper 2 is discharged. The paper is discharged onto the paper base 22c.

  During the printing process, the wiping roller 19 of the wiping device 21 is pressed against the intaglio surface of the intaglio cylinder 8 by the rotation of the eccentric bearing 19B in one direction by the actuator 19C (see FIG. 3). The excess ink on the intaglio cylinder 8 is removed.

  The wiping device 21 cleans the wiping roller 19 from which excess ink has been removed from the intaglio surface of the intaglio cylinder 8. That is, as shown in FIG. 2, excess ink adhering to the surface of the wiping roller 19 is removed by the wiping liquid ejected from the ejection nozzles 32 </ b> C, 33 </ b> C, 34 and the first wiping pad 32 and the second wiping pad 33. It is removed.

  The wiping roller 19 from which excess ink has been removed from the intaglio surface of the intaglio cylinder 8 is first supplied with a wiping liquid from the ejection nozzle 34 to the peripheral surface of the wiping roller 19. Thereby, in the first stage, excess ink adhering to the surface of the wiping roller 19 is dissolved by a large amount of wiping liquid, and the removal of excess ink by the subsequent first wiping pad 32 becomes easy.

  Next, when the first wiping pad 32 is pressed against the rotating wiping roller 19, excess ink adhering to the surface of the wiping roller 19 is removed by the first wiping pad 32. A wiping liquid is supplied to the back surface of the pad member 32B of the first wiping pad 32 from the spray nozzle 32C.

  The removal of the surplus ink by the first wiping pad 32 is a rough removal in which the surplus ink adhering to the surface of the wiping roller 19 is first scraped off and removed, and is supplied in advance by the ejection nozzle 34 and the ejection nozzle 32C. Since the excess ink is dissolved by a large amount of wiping liquid, the scraping effect is high, and the wiping liquid from the ejection nozzle 32C prevents clogging of the excess ink with respect to the pad member 32B. The removal effect is maintained.

  Then, when the second wiping pad 33 is pressed against the rotating wiping roller 19, the remaining ink after the excess ink is removed by the pad member 32 </ b> B of the first wiping pad 32 is completely removed by the second wiping pad 33. Removed. Prior to the removal of the excess ink remaining by the second wiping pad 33, the wiping liquid is supplied from the ejection nozzle 33C toward the contact surface of the portion where the pad member 33B and the wiping roller 19 are in contact.

  The removal of the surplus ink by the second wiping pad 33 is a finish removal that removes the surplus ink after the surplus ink is removed by the pad member 32B of the first wiping pad 32, and is supplied by the ejection nozzle 33C. The pad member 32B of the second wiping pad 33 is sufficiently moistened by the wiping liquid.

  Moreover, the 2nd wiping pad 33 prepares the said surrounding surface, polishing the surrounding surface of the wiping roller 19 formed with resin, and wiping off a wiping liquid.

  The material, surface shape, and rigidity of the pad member 32B of the first wiping pad 32 are selected for rough removal, and the material, surface shape, and rigidity of the pad member 33B of the second wiping pad 33 are removed by finishing. A suitable one is selected. However, the pad member 32B of the first wiping pad 32 and the pad member 33B of the second wiping pad 33 may be the same.

  During the printing process, the control device 60 controls the three-way valve 44 to be opened in the direction of arrow A and closed in the direction of arrow B, and the wiping liquid is supplied from the wiping liquid supply device 47 via the pump 46 and the three-way valve 44. Thus, the wiping liquid is ejected from the ejection nozzles 34, 32C, 33C.

  In the wiping device 21, the wiping waste liquid 35 composed of the wiping liquid ejected from the ejection nozzles 34, 32C and 33C and the excess ink wiped off by the first wiping pad 32 and the second wiping pad 33 is used as a waste liquid tank. After being temporarily stored in the wiping tank 20, it is discharged to the waste liquid treatment device 49 via the drain 41 and the pump 45.

  When the printing process is completed, the eccentric bearing 19B is rotated in the other direction via the actuator 19C of the wiping roller attaching / detaching portion 66, and the wiping roller 19 is moved away from the intaglio plate surface of the intaglio cylinder 8 (two points in FIG. 3). Position at the chain line position).

  Incidentally, the intaglio cylinder cleaning device 18 is controlled by the control device 60 to separate the brush roller 51 from the intaglio surface of the intaglio cylinder 8 via the actuator 52 of the brush roller attaching / detaching portion 67 during the printing process.

(5) Intaglio cylinder cleaning process When the intaglio cylinder 8 is cleaned, as shown in FIG. 4, the actuator 52 is operated to move the waste liquid receiver 53 from the retracted position (two-dot chain line position) to the cleaning position (solid line position). ), The brush roller 51 contacts the intaglio surface of the intaglio cylinder 8. Here, the wiping liquid from the wiping liquid supply device 47 (FIG. 2) is directly sprayed to the brush portion of the brush roller 51 through the spray nozzle 54.

  Further, as shown in FIG. 5, when the drive motor 59 is driven, the brush roller 51 rotates via the first gear 74, the second gear 75, and the third gear 76. As shown in FIG. 4, the ink, foreign matter, etc. remaining on the intaglio surface of the intaglio cylinder 8 are scraped off in the circumferential direction with respect to the intaglio surface by the rotation of the brush roller 51.

  As shown in FIG. 5, when the motor 73 is driven, the cylindrical groove cam 81 rotates, the cam follower 82 </ b> A moves along the inclined groove portion 81 </ b> A of the groove cam 81, and the lever 82 has an arrow R around the pin 85. Swing in the direction. The swing of the lever 82 causes the brush roller 51 to reciprocate in the axial direction (arrow Y direction) via the reciprocating movement receiving portion 83 having the cam follower 82B and the engaging groove portion 83A.

  Since the width of the brush roller 51 is the same as the intaglio surface of the intaglio cylinder 8, when the brush roller 51 reciprocates along the shaft 51A, the entire intaglio surface of the intaglio cylinder 8 is brushed in the left-right direction. In this way, with the intaglio surface of the intaglio cylinder 8 and the brush roller 51 in contact with each other, the brush roller 51 is reciprocated in the axial direction while rotating to remain on the intaglio surface of the rotating intaglio cylinder 8. The ink, foreign matter, etc. in the pattern portion being removed are completely removed by the brush roller 51.

  During the cleaning process, the control device 60 controls the three-way valve 44 to open in the direction of arrow B and to open in the direction of arrow A. From the wiping liquid supply device 47 (FIG. 2), the pump 46 and the three-way valve are controlled. Wiping liquid is injected from the injection nozzle 54 via the valve 44.

  Further, the intaglio cylinder cleaning device 18 causes the brush roller 51 to come into contact with the intaglio surface of the intaglio cylinder 8 via the brush roller attaching / detaching portion 67 during the cleaning process of the intaglio cylinder 8 by the control device 60. Here, the notch portions 8A, 8B and 8C (FIG. 3) in which a plate vise (not shown) for holding the intaglio cylinder 8 in the intaglio printing press 1 is stored are opposed to the brush roller 51. In the meantime, the brush roller 51 is controlled to be separated from the intaglio cylinder 8 via the brush roller attaching / detaching portion 67.

  That is, the control device 60 has a brush roller “attached” state in which the brush roller 51 is in contact with the intaglio surface of the intaglio cylinder 8 and a brush roller “detached” state in which the brush roller 51 is separated from the intaglio cylinder 8. Switching is performed based on the machine phase detected by the machine phase detection unit 65.

  The control device 60 controls the drive motor 59 and the motor 73 so as to stop the rotation of the brush roller 51 and the reciprocation in the axial direction while the brush roller 51 is separated from the intaglio surface of the intaglio cylinder 8.

  That is, the intaglio cylinder cleaning device 18 constitutes a stop device by the control device 60, the drive motor 59 and the motor 73. Further, the intaglio cylinder cleaning device 18 is controlled by the control device 60 to stop the ejection of the wiping liquid from the ejection nozzle 54 at the same time as stopping the rotation of the brush roller 51 and the reciprocation in the axial direction.

  In this case, the intaglio cylinder cleaning device 18 opens the three-way valve 44 in the arrow B direction and the arrow A direction by the control device 60 during the cleaning process of the intaglio cylinder 8. By closing a wiping liquid switching valve (not shown) provided between the nozzle 44 and the injection nozzle 54, the timing at which the notches 8A, 8B and 8C of the intaglio cylinder 8 and the brush roller 51 face each other, that is, While the brush roller 51 is separated from the intaglio surface of the intaglio cylinder 8 and the rotation of the brush roller 51 is stopped, the supply of the wiping liquid from the spray nozzle 54 is stopped.

  Further, the intaglio cylinder cleaning device 18 temporarily stores the wiping waste liquid generated when the intaglio plate surface of the intaglio cylinder 8 is cleaned by the rotation of the brush roller 51 in the waste liquid receiver 53, which is supplied via the pump 55 (FIG. 2). It is sent to the waste liquid treatment device 49 of the wiping device 21.

  In the waste liquid treatment device 49, the wiping waste liquid 35 discharged from the wiping tank 20 and the wiping waste liquid discharged from the waste liquid receiver 53 are cleaned, and the wiping liquid after the cleaning process is generated (regenerated). To the wiping liquid supply device 47. As a result, the wiping device 21 can reuse the wiping waste liquid 35 instead of discarding it as it is, so that troublesome work such as replenishment of the wiping liquid and disposal of the wiping waste liquid 35 can be omitted, and the wiping roller 19 and The intaglio cylinder 8 can be cleaned.

(6) Printing process procedure in intaglio printing machine The printing process procedure in the intaglio printing machine 1 having such a configuration will be described with reference to the flowchart of FIG.

  The control device 60 of the intaglio printing press 1 enters from the start step of the routine RT1 and proceeds to the next step SP1 to determine whether or not the print start switch 61 has been operated. If a negative result is obtained, the control device 60 returns to step SP1 again. While waiting until the print start switch 61 is operated, if it is recognized that the print start switch 61 has been operated, an affirmative result is obtained, and the process proceeds to the next step SP2.

  In step SP2, the control device 60 recognizes that the printing start switch 61 has been operated, so that the wiping roller 19 is moved to the intaglio surface of the intaglio cylinder 8 by controlling the actuator 19C of the wiping roller attaching / detaching portion 66 of the wiping device 21. As the contacted wiping roller is “attached” state, the process proceeds to the next step SP3.

  In step SP3, the control device 60 opens the three-way valve 44 in the direction of arrow A and closes it in the direction of arrow B, directly injects the wiping liquid from the injection nozzle 34 onto the wiping roller 19, and proceeds to the next step SP4. . At this time, in the intaglio printing press 1, the wiping liquid is also supplied from the wiping liquid supply device 47 to the first wiping pad 32 and the second wiping pad 33 through the ejection nozzles 32C and 33C.

  In step SP4, the control device 60 determines whether or not a predetermined number of preset printing processes have been completed, or whether or not the print stop switch 62 has been operated. If a negative result is obtained, the process returns to step SP4. On the other hand, if a positive result is obtained, the process proceeds to the next step SP5.

  In step SP5, the control device 60 recognizes that the printing process for the predetermined number of preset sheets has been completed or that the print stop switch 62 has been operated. Therefore, the actuator 19C of the wiping roller attaching / detaching portion 66 of the wiping device 21 is used. The wiping roller 19 is moved away from the intaglio surface of the intaglio cylinder 8 by controlling the wiping roller 19 to move to the next step SP6 and the print processing procedure is completed.

  Thus, in the intaglio printing press 1, during the printing process, the wiping liquid 19 is supplied to the wiping liquid via the ejection nozzle 34, the ejection nozzle 32 </ b> C of the first wiping pad 32, and the ejection nozzle 33 </ b> C of the second wiping pad 33. Then, while cleaning the wiping roller 19, the excess ink on the intaglio plate surface of the intaglio cylinder 8 is completely removed by the wiping roller 19, whereby a high-quality printing process can be executed.

(7) Intaglio Printing Machine Cleaning Process Procedure in Intaglio Printing Machine Next, the intaglio printing machine 1 cleaning process procedure in the intaglio printing machine 1 will be described with reference to the flowchart of FIG.

  The control device 60 of the intaglio printing press 1 enters from the start step of the routine RT2, moves to the next step SP11, determines whether or not the cleaning start switch 63 is operated, and returns to step SP11 again when a negative result is obtained. While waiting until the cleaning start switch 63 is operated, if it is recognized that the cleaning start switch 63 is operated, an affirmative result is obtained, and the process proceeds to the next step SP12 and step SP13.

  In step SP12, the control device 60 controls the actuator 19C of the wiping roller attaching / detaching portion 66 of the wiping device 21 in response to recognizing that the cleaning start switch 63 has been operated, whereby the wiping roller 19 is moved to the intaglio cylinder 8. The wiping roller “contact” state in contact with the intaglio surface is moved to the next step SP21.

  Here, in steps SP13 to SP20, which will be described later, after the intaglio cylinder 8 is washed with the wiping liquid, if the wiping liquid remains on the intaglio surface, the wiping liquid contains strong alkaline caustic soda (sodium hydroxide). Therefore, with the passage of time, caustic soda crystallizes and adheres, and the intaglio cylinder 8 must be cleaned separately.

  Therefore, in step SP12, the wiping liquid adhering to the wiping roller 19 when washed by the first wiping pad 32 and the second wiping pad 33 is provided downstream of the second wiping pad 33 in the rotational direction of the wiping roller 19. Wipe off with a blade (not shown). Thereafter, the clean wiping roller 19 completely wipes the wiping liquid remaining on the intaglio plate surface of the intaglio cylinder 8 after the brush roller 51 of the intaglio cylinder cleaning device 18 described later cleans the intaglio cylinder 8 with the wiping liquid. remove.

  On the other hand, in step SP13, the control device 60 opens the three-way valve 44 in the arrow A direction and the arrow B direction in response to the operation of the cleaning start switch 63, and the wiping liquid from the injection nozzle 54 is opened. Is set so that it can be directly sprayed onto the brush portion of the brush roller 51 in the intaglio cylinder cleaning device 18, and so that the wiping liquid can be sprayed directly onto the wiping roller 19 from the spray nozzle 34, the process proceeds to the next step SP14.

  In step SP14, when the controller 60 cleans the intaglio surface of the intaglio cylinder 8 with the brush roller 51, the counter 64 counts the number of times the brush roller is in the “wearing” state. The initial setting is “i = 0”, and the process proceeds to the next step SP15.

  In step SP15, the control device 60 determines whether or not the machine phase detection unit 65 has detected that it is the brush roller arrival phase, and if a negative result is obtained, the control device 60 returns to step SP15 to indicate that it is the brush roller arrival phase. On the other hand, when it is detected that the brush roller arrival phase is detected, an affirmative result is obtained and the process proceeds to the next step SP16.

  At this time, in step SP16, the control device 60 determines that it is the timing when the rear end RE of the notch 8A, 8B or 8C of the intaglio cylinder 8 and the brush roller 51 face each other, and drives the drive motor 59 to drive the brush roller 51. And the motor 73 is driven to start the reciprocating motion of the brush roller 51 in the axial direction, and then the actuator 52 of the brush roller attaching / detaching portion 67 is operated to remove the brush roller 51 from the intaglio plate of the intaglio cylinder 8. The surface is brought into contact with the surface to bring the brush roller into the “wearing” state, and the process proceeds to the next step SP17.

  In step SP17, the control device 60 increments “1” by the counter 64 when the brush roller is in the “attached” state, thereby counting up as a count value “i = i + 1”, and proceeds to the next step SP18.

  In step SP18, the control device 60 determines whether or not the machine phase detection unit 65 has detected that the brush roller is out of phase. If a negative result is obtained, the control device 60 returns to step SP18 and determines that the brush roller is out of phase. However, if it is detected that the brush roller is out of phase, an affirmative result is obtained and the process proceeds to the next step SP19.

  At this time, in step SP19, the control device 60 determines that the front end RE of the notch 8A, 8B or 8C of the intaglio cylinder 8 and the brush roller 51 face each other, and rotates the brush roller 51 via the drive motor 59. And the motor 73 is driven to stop the reciprocating movement of the brush roller 51 in the axial direction, and then the actuator 52 of the brush roller attaching / detaching portion 67 is operated to move the brush roller 51 away from the intaglio plate surface of the intaglio cylinder 8. Then, the brush roller is set in the “de-” state, and the process proceeds to the next step SP20.

  In step SP20, the control device 60 temporarily supplies the wiping liquid from the injection nozzle 54 by closing a wiping liquid switching valve (not shown) provided between the injection nozzle 54 and the three-way valve 44. Stop and move to next step SP21.

  As described above, in the controller 60 of the intaglio printing press 1, even if the supply of the wiping liquid is stopped, if the brush roller 51 is always rotated, the wiping liquid adhering to the brush tip or foreign matter such as ink residue is adhered. Scatters to the notches 8A, 8B or 8C and unintended portions of the intaglio cylinder 8, and in order to prevent this, in step SP19, the rotation of the brush roller 51 and the reciprocating motion in the axial direction are stopped to remove the brush roller And the supply of the wiping liquid is stopped.

  In step SP21, the control device 60 determines whether or not the count value “i = i0 (i0: preset value set in advance)” of the counter 64 is reached. Here, if the value of “i0” is “15”, for example, the intaglio cylinder 8 has three notches 3A, 3B, and 3C. It is determined that the cleaning of the intaglio cylinder 8 by 18 is finished.

  If a negative result is obtained in step SP21, this indicates that the count value “i = i0” of the counter 64 is not satisfied, that is, the intaglio cylinder cylinder 8 is continuously cleaned by the intaglio cylinder cylinder cleaning device 18. The control device 60 returns to step SP15 and repeats the subsequent processing.

  On the other hand, if an affirmative result is obtained in step SP21, the control device 60 is in the “roll-off” state of the brush roller, so the process proceeds to the next step SP22 while maintaining this state.

  In step SP22, since the controller 60 finishes cleaning the intaglio cylinder 8 by the intaglio cylinder cleaning device 18, the controller 19 controls the actuator 19C of the wiping attachment / detachment portion 66 of the wiping device 21 so that the wiping roller 19 is in the "detached" state. Then, the process proceeds to the next step SP23.

  In step SP23, the control device 60 completes the cleaning process of the intaglio cylinder 8 by the intaglio cylinder cleaning device 18, and thus closes the three-way valve 44 in the direction of arrow A and also in the direction of arrow B, and then proceeds to the next step SP24. Thus, the cleaning process for the intaglio cylinder 8 is completed.

  As described above, the intaglio printing machine 1 is not configured to be manually cleaned manually by an operator as in the past, and the intaglio cylinder 8 is automatically cleaned by the brush roller 51 of the intaglio cylinder cleaning device 18. By using the wiping liquid used in the wiping device 21 for the cleaning process, it is possible to obtain a suitable dissolving power with respect to the ink used in the intaglio cylinder 8, so that the ink removal efficiency by the intaglio cylinder cleaning device 18 is conventionally increased. The intaglio cylinder 8 can be efficiently cleaned as compared with the above.

(8) Operation and Effect In the above configuration, the intaglio printing press 1 is provided with the intaglio cylinder cleaning device 18 as an ink removing device, and from the jet nozzle 54 of the intaglio cylinder cleaning device 18 to the intaglio cylinder 8 after the printing process. By supplying the wiping liquid and washing the intaglio cylinder 8 with the brush roller 51, the brush roller 51 can efficiently and efficiently dissolve the ink and the like remaining on the intaglio surface of the intaglio cylinder 8. It can be removed reliably.

  At this time, in the intaglio printing press 1, the brush roller 51 of the intaglio cylinder cleaning device 18 is rotated while being in contact with the intaglio surface of the intaglio cylinder 8, and the brush roller 51 is reciprocated in the axial direction. It is possible to reliably remove the ink, foreign matter, and the like of the pattern portion remaining on the intaglio surface of the cylinder 8.

  The intaglio printing machine 1 is configured to supply the wiping liquid used by the brush roller 51 of the intaglio cylinder cleaning apparatus 18 from the wiping liquid supply apparatus 47 of the wiping apparatus 21. That is, in the intaglio printing press 1, the intaglio cylinder cleaning device can be constituted by the wiping liquid supply device 47 and the intaglio cylinder cleaning device 18, and the wiping liquid supply device 47 of the wiping device 21 is also used as the intaglio cylinder cleaning device 18. Therefore, it is not necessary to separately provide a cleaning liquid or a cleaning liquid storage tank dedicated to the intaglio cylinder 8, and it is possible to simplify the configuration and reduce the cost, and work from complicated work such as management of the remaining amount of cleaning liquid Can be released.

  Further, the control device 60 of the intaglio printing press 1 contacts the brush roller 51 with the intaglio surface of the intaglio cylinder 8 via the brush roller attaching / detaching portion 67 in response to a command to start cleaning the intaglio cylinder 8 by the intaglio cylinder cleaning device 18. The wiping roller 19 is controlled to come into contact with the intaglio surface of the intaglio cylinder 8 via the wiping roller attaching / detaching portion 66 of the wiping device 21.

  Thereby, in the intaglio printing press 1, when the intaglio plate surface of the intaglio cylinder 8 is washed by the brush roller 51, the wiping residual liquid adhering to the intaglio plate surface can be wiped off by the wiping roller 19, so that it is included in the wiping liquid. A situation in which strong alkaline caustic soda (sodium hydroxide) crystallizes over time and remains on the intaglio surface of the intaglio cylinder 8 can be prevented in advance, and thus high printing quality can be maintained. .

  That is, in the intaglio printing machine 1, the function of wiping excess ink adhering to the intaglio surface of the intaglio cylinder 8 by the wiping roller 19 with respect to the wiping roller 19 of the wiping device 21 used during the printing process, and the intaglio cylinder 8 cleaning process. By having two functions of wiping off and removing the wiping residual liquid adhering to the intaglio surface inside, the printing process and the intaglio cylinder 8 cleaning process are efficiently executed without complicating the configuration. be able to.

  Further, the intaglio printing machine 1 is configured so that when the notches 8A, 8B and 8C of the intaglio cylinder 8 and the brush roller 51 face each other, the rotation of the brush roller 51 is stopped and then separated from the intaglio cylinder 8 and from the injection nozzle 54. By stopping the supply of the wiping liquid, foreign matters such as wiping liquid and ink residue are scattered by the idling of the brush roller 51 to the notches 8A, 8B and 8C where the wiping residual liquid cannot be removed by the wiping roller 19. It is possible to avoid in advance a situation in which foreign matter is scattered to an unintended location.

  The intaglio printing machine 1 controls to stop the cleaning process by the brush roller 51 on the basis of the count value i by the counter 64 in the “wearing” state of the brush roller in which the brush roller 51 of the intaglio cylinder cleaning device 18 is in contact with the intaglio cylinder 8. By doing in this way, the frequency | count of washing | cleaning of the intaglio in the intaglio cylinder 8 can be designated, and a washing process can be performed correctly.
