いる。2. Description of the Related Art A plate-like cylinder provided with a plate body for printing a design or the like on an outer peripheral surface of a metal cylinder plated with copper chrome, and a band-like member between an impression cylinder pressed against the outer surface of the plate cylinder. The rotary gravure printing machine, which prints through a base paper, is widely used for printing a large number of publications because of its high printing speed and high printing efficiency. In the printing section of this rotary gravure printing machine, the rotary shaft is rotatably supported by a bearing so that the plate cylinder fixed to the rotary shaft partially lands on the ink stored in the ink reservoir. A doctor for scraping off excess ink that has adhered is joined to the outer surface of, and an impression cylinder formed of a rubber roller or the like is pivotally supported on the plate cylinder in a pressure contact manner. And
Transfer the roll-wound strip-shaped base paper to the printing unit while pulling it out from the paper feed unit, sandwich the strip-shaped base paper between the impression cylinder and plate cylinder of the printing unit, and place the pattern printing position, etc. at a position diagonally above and behind the printing unit. While tension is applied to the belt-shaped base paper by a tension roller provided for adjusting, the belt-shaped base paper is pressed against the plate cylinder by an impression cylinder to print a predetermined pattern on the belt-shaped base paper, and then transferred to the next step.

されている。During the printing operation, when the pattern printing by one plate cylinder is completed and the plate cylinder is replaced for printing another pattern next time, the drive gear fixed to the rotary shaft of the plate cylinder is used. It was necessary to replace the plate cylinder by removing the above parts, pulling it out from the bearing part, inserting the rotary shaft of a new plate cylinder into the bearing part again, and attaching the drive gear. Therefore, in recent years, without attaching the plate cylinder to the rotary shaft, as shown in FIG. 8, the trapezoidal left and right fitting bodies of the sandwiching shaft support portions provided in the printing unit can be freely attached to and detached from both ends of the center hole of the plate cylinder. Shaftless rotary gravure printing machines (hereinafter abbreviated as "shaftless printing machines"), which can be fastened and pinched to quickly exchange plate cylinders compatible with printing various designs in the printing section, have been installed in many printing plants. There is.

汚される等の問題があった。However, in the shaftless printing machine, the gap width between the left and right fitting bodies of the sandwiching shaft supporting portion supporting the plate cylinder is limited so that the plate cylinder having a predetermined length or less can be sandwiched. It is impossible, and even if the plate on which the pattern is printed is narrow, it is necessary to use a plate cylinder with a predetermined length or more. Therefore, even if the plate is narrow, the manufacturing cost of the plate cylinder Has the disadvantage of being expensive and not saving printing costs. For plate cylinders that are too short to be sandwiched between the left and right fitting bodies of the sandwiching shaft support, use a method in which a cylindrical adjuster is jointly connected at both ends to print while sandwiching between the left and right fitting bodies of the sandwiching shaft support. However, when this adjuster is used, the rotating plate cylinder swings, or the center of the plate cylinder is aligned with the center of the band-shaped cardboard, so that it takes a lot of time to center the band-shaped cardboard. There is a problem in that the printing is likely to be displaced from the predetermined position, or the strip-shaped cardboard is stained and stained with the excess ink attached to the adjuster.

い。Next, according to the method of mounting the plate cylinder of the shaftless printing machine according to the third aspect, the rolled roll-shaped base paper is pulled out from the paper feeding section, and the band-shaped base paper is placed on the impression cylinder and below the impression cylinder. A method for mounting a plate cylinder of a shaftless printing machine, which prints a pattern and the like continuously while sandwiching it with the plate cylinder arranged in Positioning and locking the plate cylinder at a desired position of the shaft,
The plate cylinder attached to the plate cylinder mounting shaft is arranged in the printing unit, and in that state, the plate cylinder mounting shaft is attached and detachably supported by a sandwiching shaft so that the plate cylinder of a desired size is placed in the printing unit. Since it is replaceably attached, it is possible to use a plate cylinder having an arbitrary length and a necessary limit size according to a design to be printed, and thus a printing cost can be significantly saved. Also, since it is not necessary to connect the adjuster even with a plate cylinder having a short length, both edges of the strip-shaped cardboard are not contaminated with ink, and
Ink in the ink reservoir is not wasted. Furthermore, the plate cylinder can be accurately aligned with the printing position of the band-shaped base paper for printing, and printing errors such as misalignment do not occur.
