[0063] refer to Figure 1 to Figure 12 , which show a printing unit constructed according to a first embodiment of the present invention. Parts or elements corresponding to the above-mentioned parts or elements (which do not always have the same structure) are denoted by the same reference numerals.
[0064] Such as figure 1 As shown, the printing unit of the rotary printing press in this embodiment is configured as a perfecting printing press, which prints on both sides of the web 11 at a time. The printing unit is thus equipped with an inkjet device 10a and a dampener 12a located above the web 11 and an inkjet device 10b and a dampener 12b located below the web 11 . The inkjet units 10a, 10b are equipped with plate cylinders 8a, 8b and blanket cylinders 9a, 9b, respectively. In the rotary printing machine of this embodiment, the plate cylinder 8 and the blanket cylinder 9 (the plate cylinder and the blanket cylinder are called printing cylinders in some cases) can be rep...

[0104] refer to Figure 13 with Figure 14 , which show a printing unit constructed according to a second embodiment of the present invention. Parts or elements at the same positions as those of the first embodiment described above are denoted by the same reference numerals.
[0105] This embodiment differs from the first embodiment in that the movable frame is supported by a frame. That is, if Figure 13 with Figure 14 As shown, a stationary bracket 26k fixed to one frame 13m is provided with an axial linear bearing 28k, and an axially movable bracket 49 is supported by the axial linear bearing 28k. And, the movable frame 25k is supported by the axial movement bracket 49 through the lateral linear bearing 29k. The frame 13m is connected with the axial movement bracket 49 through the axial movement driver 30k. The axially movable support 49 is connected with the movable frame 25k through a lateral direct drive 31k. Thus, the operation of the axial movement driver 30k c...

[0108] refer to Figure 15 , which shows a printing unit constructed according to a third embodiment of the oil of the present invention. Parts or elements at the same positions as those of the first embodiment described above are denoted by the same reference numerals.
[0109] In this embodiment, the lateral movement stand is structurally different from the first embodiment. That is, in the first embodiment, the lateral movement brackets 27a, 27b are separated from each other. On the other hand, in the third embodiment, the lateral movement brackets 27a, 27b are connected by a connecting member 27c, and they are integrally formed as a side bracket 27k. Thanks to this, in addition to the same advantages as the first embodiment, the connection member 27c can be used as one cover, and the two lateral movement actuators 31 can be reduced to one actuator. For example, the upper drive can be omitted. Since the support stiffness is increased, the printing cylinder support arms ...

Abstract
A rotary press that is capable of interchanging printing cylinders in a short time with less labor. The rotary press includes a first supporting device (81, 91) for supporting one end of a printing cylinder (8, 9). The first supporting device (81, 91) is provided in a movable frame (25) arranged outside a first side frame (13m). A second supporting device (85, 95) , for supporting the other end portion of the printing cylinder (8, 9), is provided in a second side frame (13d). The movable frame (25) is moved in an axial direction of the printing cylinder (8, 9) with respect to the first side frame (13m) by a first frame-moving device (30), whereby the first supporting device (81, 91) is attached on or detached from the one end portion of the printing cylinder (8, 9). With the first supporting device (81, 91) detached from the one endportionof the printing cylinder (8, 9) by axial movement of the movable frame (25) , the movable frame (25) is further moved with respect to the first side frame (13m) by a second frame-moving device (31).
Description
technical field [0001] The invention relates to a rotary printing machine for changing the printing length by replacing the printing cylinder. technical background [0002] Figure 24 is a schematic diagram showing an example of a rotary printing press. In this rotary printing machine, a roll of paper (rolled paper) is set in a paper feeder 1 . The web 11 is fed continuously from the feed unit 1 to a printing press unit 3 where the web 1 is printed. In case the printing press unit 3 performs multi-color printing, it includes printing units 7a to 7d corresponding to the number of printing colors. exist Figure 24 In , four-color printing is shown. The printing web 11 passes through a web transfer 5 and is conveyed to a folder 6 where it is cut into sheets of suitable length. After folding, the paper is removed as a folded book. Figure 25 A conventional printing unit 7 ( Figure 24 An example of printing units 7a to 7d) in . The printing unit consists of an inkjet devic...
