Description

  The present invention relates to a liquid ejection confirmation jig for confirming the degree of cleaning liquid ejection from an ejection nozzle of a wiping device of an intaglio printing press.

  The intaglio printing machine supplies ink onto the intaglio plate of an intaglio cylinder having an intaglio plate attached to its peripheral surface, and removes excess ink from the intaglio plate with a wiping roll of a wiping device, thereby holding the paper held on the impression cylinder In contrast, the ink in the groove of the intaglio is printed. FIG. 4 shows a schematic structure of an example of such a wiping device for an intaglio printing press.

  As shown in FIG. 4, a support shaft 12 a of a wiping roll 12 that is in contact with the intaglio on the peripheral surface of the intaglio cylinder 20 is detachably and rotatably supported on the upper portion of the wiping tank 11. A plurality of (two in this example) wiping pads 13 that are in contact with the outer peripheral surface of the wiping roll 12 over the entire length in the axial direction are supported inside the wiping tank 11. In the vicinity of the wiping pad 13, the wiping roll 12 and a plurality of injection nozzles 14 with the injection ports 14 a directed to the wiping pad 13 are provided at predetermined intervals along the axial direction and the circumferential direction of the wiping roll 12. Yes.

  The base end side of the injection nozzle 14 communicates with the feed port side of the feed pump 16. The inlet side of the feed pump 16 communicates with a cleaning liquid tank 17 that stores a cleaning liquid (wiping liquid) 1. A drainage pipe 15 is connected to the bottom of the wiping tank 11.

  In the wiping device 10 configured as described above, the feed pump 16 is operated to inject the cleaning liquid 1 in the cleaning liquid tank 17 from the injection port 14a of the injection nozzle 14 and drive a drive motor (not shown). When the wiping roll 12 is driven to rotate, the wiping roll 12 wipes excess ink on the intaglio plate of the intaglio cylinder 20 from the intaglio plate, and the spray nozzle 14 applies the cleaning liquid to the wiping roll 12 and the wiping pad 13. The ink wiped from the wiping roll 12 by the wiping pad 13 while being sprayed 1 is scraped off from the wiping roll 12 and washed, and the washed ink is collected in the wiping tank 11 together with the cleaning liquid 1. So that it can be discharged from the drainage pipe 15 to the outside. Going on.

  By the way, in the wiping apparatus 10 as described above, as the ink is used, the washed and removed ink gradually adheres and accumulates on the ejection port 14a of the ejection nozzle 14 to cause clogging and the like. Since the cleaning liquid 1 gradually becomes difficult to spray, it is necessary to clean the spray nozzle 14a of the spray nozzle 14 that has been clogged during maintenance and inspection, but the wiping roll 12 and the like is an obstacle. Thus, it was not possible to confirm the spraying state of the cleaning liquid 1 from the spraying port 14a of the spraying nozzle 14.

  Therefore, it is conceivable to remove the wiping roll 12 from the wiping tank 11 and check the injection state of the cleaning liquid 1, but since the injection amount of the cleaning liquid 1 from the injection port 14 a of the injection nozzle 14 is very large, It was not something that can be confirmed with. Therefore, at the time of maintenance inspection and the like, the injection ports 14a of all the injection nozzles 14 have to be cleaned every time, which is very troublesome.

  For this reason, there has been a strong demand to be able to reduce the time and effort required for cleaning the ejection ports 14a of the ejection nozzles 14 of the wiping device 10 of the intaglio printing press during maintenance and inspection.

  The present invention, which has been made to solve the above-mentioned problems, is a liquid injection confirmation jig for confirming the injection state of a cleaning liquid injection nozzle for cleaning a wiping roll supported by a wiping tank of a wiping device of an intaglio printing press. Transparent to be able to visually check the spraying state of the cleaning liquid from the spraying port of the spraying nozzle, which is detachably supported by the wiping tank instead of the wiping roll so as to be positioned in front of the spraying port of the spraying nozzle A confirmation plate made of a material is provided.

  The present invention further includes a support shaft that supports the check plate and is detachably supported by the wiping tank in the liquid jet check jig described above, and the check plate includes an axis of the support shaft. It is characterized by having an arc shape located on the same axis.

  Moreover, the present invention is characterized in that in the above-described liquid ejection confirmation jig, the confirmation plate has an arc shape having the same curvature as the wiping roll.

  According to the liquid ejection confirmation jig according to the present invention, after the confirmation plate is supported by the wiping tank so as to be positioned in front of the ejection port of the ejection nozzle instead of the wiping roll of the wiping device of the intaglio printing press, the ejection is performed. When the cleaning liquid is sprayed from the nozzle injection port, the cleaning liquid is sprayed on the confirmation plate.By looking into the confirmation plate, the state of the cleaning liquid sprayed from the injection nozzle injection port can be visually confirmed. Since it is possible to easily identify the injection nozzles that are causing problems such as clogging, it is only necessary to clean the specified injection nozzles, which eliminates the need for maintenance and inspection of the wiping device of the intaglio printing press. It can be greatly reduced.
