、版替えを行っている。Plate cylinders 2 (2a, 2b, 2c and 2
The plate 3 (3a+3b, 3
The mounting positions of 3a) and 3a) differ depending on the printing unit, so in a certain printing unit (for example, the first color printing unit) 3a), even if the mounting position of plate 3a is convenient for plate changes, The mounting positions of the plates of other printing units are not necessarily in convenient positions for plate changes. Therefore, each printing unit is moved to a convenient position for changing the plate, and then the plate is changed.

正している（以下色間見当という）。このため第１図の
モータ１３の代シに小型モータ３１が設けられている。In the above example, if printing unit (1a) for the first color is located in a convenient front position for plate replacement, first print unit (3) on plate cylinder 2a for the first color.
Then, by rotating the line shaft 4, the plate 3b of the second color plate cylinder 2b is attached to a position convenient for plate replacement, and the plate is replaced. After that, the above-mentioned operations are repeated one after another, and the plates are replaced. Therefore, after all the plate cylinders 20 and 3 of each unit are replaced, the phases of the plate cylinders 2 are mechanically aligned (hereinafter referred to as mechanical register). However, the color registration of the actually printed image may have slight errors due to the installation accuracy of the plate cylinder and the deviation of the image printed on the plate from the plate installation reference position, so a small motor is installed to adjust the color registration. to correct this error (hereinafter referred to as intercolor registration). For this reason, a small motor 31 is provided in place of the motor 13 in FIG.
この小型モータ３１および関連部品等は、第４図と同一
なので、後述の実施例で説明する。Since this small motor 31 and related parts are the same as those shown in FIG. 4, they will be explained in the embodiment described later.

に来るようにしたのち、版を取替える必要があり、従っ
て労力及び時間がか＼る等の課題がある。According to the above-mentioned conventional technology, since the mounting position of the plate is different for each printing unit, the mounting position of the plate for each printing unit is set at a convenient position for plate replacement (a predetermined position).
It is necessary to change the plate after making sure that the printing is done properly, which poses problems such as labor and time.
〔課題を解決するための手段〕 各印刷ユニットで同時版替えが出来るようにする。[Means to solve the problem] To enable simultaneous plate changes in each printing unit.

When the printing unit is driven from the line shaft through the differential (as in the past), the web generator of the differential is firmly fixed by the brake of the motor, so no mechanical phase shift of the plate cylinder occurs. . In addition, during normal operation, when driving the unit for simultaneous plate change (a unique mode of the present invention), and when adjusting color registration (same as conventional),
(referred to as the drive of the second and third moges), the differential is driven by the line shaft to firmly fix the web generator, the line shaft is fixed and the web generator is driven by the motor, and the web generator is driven by the motor. It becomes possible to drive the differential with the line shaft while driving at low speed.

Further, the position detection encoder n is energized, counts the amount of rotation of the plate cylinder 2, and sends the counted amount to a control device (not shown). The high speed rotation of the motor 13 is caused by the gears 14, 15, the web generator F of the differential 7, -! It is transmitted to the gear 12 of the plate cylinder via the bevel gears 8 and 9 via the circular spline D1, the flex spline P, the circular spline S, and the output shaft 17 on which the circular spline S is fixedly attached.

る。Therefore, the mounting position of the plate 3 mounted on the plate cylinder 2 of each printing unit is at a predetermined position convenient for plate change. Next, after the simultaneous plate change, the plate cylinders are returned to their mutual positions in mechanical register before the plate layer. At this time as well, the motor 13 rotates at high speed, and when the plate cylinder 2 is returned to its original position by the amount counted by the position detection encoder n, the motor 13 rotates using the same drive path as in the simultaneous plate change described above. stops. The control device controls the motor 13, which rotates in the normal direction when the counted amount exceeds 180 degrees, and rotates in the reverse direction when the counted amount is less than 180 degrees.
