Problems solved by technology

When the printing operation is continued while the ink filled in the groove of the wiring pattern is dry and solidified, the wiring pattern printed on the substrate may be damaged, so cleaning is required when the gravure printing machine has been printing for a specified period of time. In gravure, as mentioned above, the width of the groove of the wiring pattern is narrow, so the cleaning work of the gravure is cumbersome, which places a heavy burden on the operator

Embodiment 1

[0041] according to Figure 1~6 The gravure printing machine and the operating method of the gravure printing machine in Example 1 of the present invention will be described.

[0042] Such as figure 1 and figure 2 As shown, in the gravure printing machine 100 of this embodiment, the base material 1 as the object is loaded and supported on the platform 110, and the base material 1 is a sheet-like resin film, flexible glass, or the like. In addition, on the side of the long side of the platform 110 ( figure 1 in the left side), so that the axial direction is toward the width direction of the platform 110 ( figure 1 In the direction perpendicular to the paper surface), a printing plate cylinder (gravure cylinder) 120 can be rotatably arranged, and a sleeve-type intaglio plate (gravure plate) 124 is installed on the outer periphery of the printing plate cylinder 120, The intaglio plate 124 is formed with a groove (width: about 1 to 100 μm, depth: about 1 to 100 μm) as a wirin...

Embodiment 2

[0068] according to Figure 7 The gravure printing machine and the operation method of the gravure printing machine according to the second embodiment of the present invention will be described.

[0069] The above-mentioned embodiment 1 illustrates that the printing plate cylinder 120 is provided with a first scraper blade 121, a second scraper blade 122 and a scraper 123. There are examples of the first doctor blade 121 and the second doctor blade 122 . The other configurations are substantially the same as those of the above-mentioned first embodiment, and the same reference numerals are assigned to the same components below, and repeated descriptions are appropriately omitted, and the differences will be mainly described.

[0070] In this example, with the removal of the figure 1 In the scraper 123 shown in FIG.

[0071] In addition, the cylinder 144 for the first scraper blade can move the front end of the first scraper blade 121 between a pressing position contacting t...

Embodiment 3

[0081] according to Figure 8 The gravure printing machine and the operating method of the gravure printing machine according to Example 3 of the present invention will be described.

[0082]The above-mentioned embodiment 1 shows the example that the printing plate cylinder 120 is provided with the first scraper blade 121, the second scraper blade 122 and the scraper 123. This embodiment cancels the first scraper blade 121 of the above-mentioned embodiment 1, and shows that The plate cylinder 120 is provided with only an example of the second doctor blade 122 and the doctor blade 123 . The other configurations are substantially the same as those of the above-mentioned first embodiment, and the same reference numerals are assigned to the same components below, and repeated descriptions are appropriately omitted, and the differences will be mainly described.

[0083] In this example, with the cancellation of figure 1 The above-mentioned first doctor blade 121 and the doctor bl...

Abstract

The present invention provides a gravure printing machine and a method of operating the gravure printing machine, which can prevent the drying of the plate tank during the period other than the transfer process of transferring from the printing plate cylinder to the blanket cylinder or substrate. The photogravure printing machine comprises: a printing plate cylinder (120), a concave portion for filling ink (2) is arranged on the plate; Layout contact movement or separation movement. The gravure printing machine has a receiving process of transferring the ink (2) filled in the concave portion to the blanket cylinder (110) in contact with the printing plate cylinder (120), and when the receiving process is not performed, the first scraper blade (121) is separated from the plate surface of the plate cylinder (120) to form a film of ink (2) covering the concave portion of the plate cylinder (120). On the other hand, when performing the receiving process, the first doctor blade The front end of the sheet (121) is in contact with the plate surface of the plate cylinder (120), and the ink (2) adhering to parts other than the recesses is removed, leaving only the ink (2) filled in the recesses.

Description

technical field [0001] The present invention relates to a gravure printing machine and a method for operating the gravure printing machine. Background technique [0002] In the field of printed electronics (PE), the use of gravure printing machines is being investigated. For example, in a flatbed type gravure printing machine in which a sheet-like base material is placed on a flat plate (platform) and printed, an intaglio plate (gravure plate) with a groove of a wiring pattern formed thereon is mounted on a plate cylinder (gravure cylinder). On the outer periphery, ink is supplied to the intaglio plate while the plate cylinder rotates by bringing the doctor blade into contact with the plate cylinder, and the grooves of the intaglio plate are scraped off from the intaglio plate while filling ink into the grooves of the intaglio plate Ink adhering to the other parts, and the blanket cylinder (blanket cylinder) with a silicon blanket wound around it is rotated while in contact...
