の上から永年の夢として渇望されていた。b. Prior art The installation and removal of the printing plate from the circumferential surface of the plate cylinder, as well as the loading and unloading of the printing plate, have conventionally been performed exclusively manually by workers, and conventionally mechanized printing Even in the case of a hook operation mechanism for tightening the plate grip end, a tool was fitted to the end of the operation shaft and the rotation operation was performed manually. Therefore, when installing printing plates, workers must carry in and feed the printing plate from the outside to the plate cylinder, rotate the plate cylinder to move the hook installed on the plate cylinder to the optimal position for installation, and untighten the hook. position, align the leading edge of the printing plate with the bent edge, return the hook to the tightening position, and rotate the plate cylinder, for example, 1/2 turn while winding up the printing plate, to align the plate with the bent part of the trailing edge and the hook. It is necessary to carry out the work of fitting the plates in sequence and in close cooperation with each other, and when removing the printing plate, the work, which is generally the opposite of the above, must be carried out in sequence and in close cooperation with each other. If the coordination is not smooth, the work becomes laborious, takes time and effort, and causes problems in newspaper printing, for example, where speedy reporting is vital. The work required skill. In particular, when printing newspapers, it is necessary to attach and detach the printing plate several times every day, which requires a huge amount of labor costs, and what's more, even the slightest mistake can cause your hands and fingers to get caught in the plate cylinder. Accidents can occur, so automating the loading and unloading of printing plates has been a long-awaited dream for the sake of speedy and reliable work execution, significant savings in labor costs, and safety measures.

The rolling of the wheel 27 along the rail 26 as the motor 31 rotates causes the chassis 29 to be moved to the printing plate 69.
While displacing the plate cylinder 24 on which it is placed to a predetermined position in the longitudinal direction (positioning in the left and right direction),
With the rotation of the step motor 47, the slider block 44 and the thrust rod 20 integrated therewith are moved back to the rearmost position, while the second board 17 is rotated by the motor 49, so that the rubber rollers 72 and 80 are aligned vertically. In this position, the step motor 41 is rotated to lower the first substrate 16 to a height approximately equal to the height at which the grip-side bent portion 69a of the printing plate 69 is placed.
