ている。The longitudinal direction of these plate cylinder mounting tables 84 corresponds to the ink pan 1.
The side plate 18A is installed in the ink pan 18 so that the side plate 18A is inserted into the four portions 84A that are substantially perpendicular to the longitudinal direction of the ink pan 8 and formed near both ends in the longitudinal direction. A guide roller 86 is pivotally supported within this recess 84A.
By contacting the upper end of the side plate 18A, the plate cylinder mounting table 84 can be moved in the longitudinal direction of the ink pan 18 (in the direction indicated by the arrow). However, a set screw 88 is screwed into the end of the plate cylinder mounting table 84, and when the tip of the threaded portion is pressed against the outer surface of the side plate 18A, the plate cylinder is
The structure is such that movement of the ii stand 84 in the direction of the arrow can be restricted.

介してインキパン１８へ載置されることになる。In this state, by rotating the handle 82 of the truck 32, the lifting shaft 56 is pulled into the support cylinder 54, and the ink pan 18 is lowered. Here, a pair of plate cylinder mounting tables 84 shown in FIG. 1 are placed on the side plate 18A, and the handle 82 is operated again to raise the ink pan 18. After the ink pan 18 is raised until the support roller 92 in the recess 84C of the plate cylinder mounting table 84 comes into contact with the plate cylinder 12, the tapered cone shafts 94 are separated from each other and pulled out from the taper connecting hole 12A of the plate cylinder 12. As a result, as shown in FIG. 1, the plate cylinder 12 is separated from the tapered cone shaft 94 and placed on the ink pan 18 via the plate cylinder mounting table 84.

節度手段を設けてもよい。In this way, the plate cylinder 12 is connected to the ink pan 18! Since the plate cylinder 12 is placed and moved to the processing chamber by the carriage 32, there is no need to remove ink adhering to the plate cylinder 12 when it is removed from the printing press, as is the case in the prior art. Also, like this, move the trolley 32 to arrow F.
Since it is necessary to move in the G and H directions, moderation means may be provided so that the wheels 36 can rotate about an axis perpendicular to the truck 32 every 90''.

The taper connecting hole 12A is moved to a coaxial position with the taper cone shaft 94 and stopped, and the pair of taper cone shafts 94 are brought closer to each other. As a result, the tapered cone 96 is inserted into the tapered connecting hole 12A. In this case, the key 96A of the taper cone 96 should be inserted into the keyway 1 accurately.
2B, the plate cylinder I2 is rotated around its axis on the support roller 92. In addition, in order to appropriately arrange the plate cylinder 12 between the pair of tapered cone shafts 94, the plate cylinder 12 is
It is necessary to move the plate cylinder mounting table 84 in the axial direction.
is mounted on the side plate 18A via the guide roller 86, so that the plate cylinder 12 can be easily moved in the axial direction.

が再開可能となる。After the taper cone shaft 94 and the plate cylinder 12 are connected, the handle 82 is rotated to lower the ink pan 18 by a predetermined amount. If the plate cylinder mounting table 84 is removed from the ink pan 18 and the ink pan 18 is filled with ink 22, the printing operation can be restarted.

へと大幅に短縮することができた。On the other hand, the used plate cylinder 12 and ink pan 18 brought into the processing chamber 98 are subjected to post-processing operations such as ink removal, cleaning, and oil coating. Since this work is carried out after the new plate cylinder 12 and ink pan 18 have already been loaded into the printing press, there is no need to carry out the work while the printing press is stopped, and the operating efficiency of the printing press can be improved. - For example, in a gravure printing machine for seven-color printing equipped with seven printing units M, it takes about two hours including cleaning time to replace the plate cylinder in the printing unit, but in this example, this We were able to significantly shorten the time to approximately 40 minutes.
このグラビア印刷機Ｐにおける他の印刷ユニットの版胴
を交換するのも上記と同様の手順で行うことができる。The plate cylinders of other printing units in this gravure printing machine P can also be replaced using the same procedure as described above.
