Description of the Related Art A conventional plate mounting apparatus is mounted on the plate guide table 20 with a plate positioning pin 21 tiltably attached to the lower end of a plate guide table 20 which is inclined and held as shown in FIG. Plate positioning pin 2 to the lower edge of plate 12
U-shaped grooves 13a and 13b that engage with 1a and 21b are provided,
In the vise side vise 18 of the plate cylinder 15, the U-shaped groove 13a of the printing plate 12,
Plate positioning pins 17a and 17b that engage with 13b are provided. As a procedure for mounting the printing plate 12, the plate guide table 20 is moved by a proximity device and the vise side vise 1 of the plate cylinder 15 is set.
The plate positioning pin 21 is tilted at a position close to 8 (the area surrounded by the one-dot chain line in the figure), and the plate 12 slides down on the plate guide table 20 by its own weight as shown in FIGS. 6 and 7. Thereby, the U-shaped grooves 13a, 13 of the printing plate
b is engaged with the plate positioning pin 17 of the vise side vise 18 to position the printing plate 12 with respect to the plate cylinder 15. After the positioning is performed as described above, the lower edge of the printing plate 12 is held by the bite side vise 18.

要があった。The conventional plate mounting device has the following problems because it is constructed and functions as described above. That is, as shown in FIG. 6 and FIG.
From the position where the die grooves 13a and 13b are close to the vise side vise 18, let the plate 12 slide down by its own weight during L in the figure.
Since it directly contacts the plate positioning pin 17 of the plate cylinder 15, the R portions of the U-shaped grooves 13a and 13b are deformed by the impact force,
The entrance Y of the U-shaped groove may be deformed. For this reason, the deformation may cause a mounting error of the printing plate 12 on the plate cylinder 15, which may cause misregistration to deteriorate the printing quality. Also U
The plate 12 in which the R portion of the mold groove 13 is deformed cannot be reused. Furthermore, when printing with the plate 12 attached,
The position of the plate guide table 20 and the plate cylinder 15 is not aligned when another new printing plate 12 is attached after printing with the left and right register (movement in the plate cylinder axis direction) adjusted in relation to the plate printing accuracy. . Therefore, it was necessary to return the left and right registration to the origin again.

A plate guide table, a table locating pin that projects from the vise side vise of the plate cylinder and engages with the lower end of the plate guide table, and a table positioning pin that projects into the vise side vise of the plate cylinder and is provided on the printing plate. And a plate positioning pin that engages with the plate positioning groove, a guide having a guide groove is provided at the lower end of the plate guide table, and the printing plate is provided immediately before the guide groove of the guide contacts the table positioning pin. Since the suction holding of the plate is released and only the minute gap is slid down, and the plate comes into contact with the plate positioning pin of the plate cylinder, after the plate starts to be accurately guided together with the plate guide table, The plate positioning groove of the plate Since entering the plate positioning pins bite example plate clamp of the body that is not the corners of the plate positioning groove is deformed Upon pins. Further, since the sliding difference of the printing plate is small, almost no impact load acts on the R portion of the printing plate positioning groove formed on the plate. For this reason, no deformation occurs in the groove portion of the printing plate positioning groove, and the mounting accuracy on the plate cylinder is significantly improved. Therefore, the printing plate can be repeatedly used. Further, since the guide groove of the guide is started to be guided by the table positioning pin, the plate positioning groove on the table is arranged to be guided by the plate positioning pin of the plate cylinder. Even if the plate cylinder moves in the circumferential direction, the axial direction, and the twisting direction, the plate can be mounted with reference to the plate cylinder without returning the plate cylinder to the original position.
