である。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a rotary printing press including an offset printing press having a plurality of printing units, the printing unit having a length longer than the circumference of the plate cylinder of each printing unit. This invention relates to a printing machine for long printed matter that is capable of printing long printed matter.
従来の輪転印刷機にあつては、用紙の走行方向
における印刷物の１リピート長は、印刷ユニツト
の版胴の円周長しかとれなかつた。 In conventional rotary printing presses, one repeat length of printed matter in the paper running direction can only be equal to the circumferential length of the plate cylinder of the printing unit.

加してしまうという問題があつた。[Problem to be solved by the invention] Therefore, in order to obtain printed matter with a long print length for one repeat in the paper running direction, it is necessary to use a plate cylinder with a corresponding circumference and a plate with a large diameter. This poses a problem in that each printing unit becomes large-sized, and the equipment cost increases significantly due to longer printing times.

経路長が変ることなく行なわれる。 The present invention was developed in consideration of the above, and it is possible to obtain printed matter having a repeat length longer than the circumference of the plate cylinder of each printing unit at low cost.
In addition, the impression cylinder in each printing unit can be moved in and out of contact with the blanket cylinder without changing the running path of the paper, making it possible to obtain long printed matter of good quality without shifting the image. The aim is to provide printing machines for
Its structure consists of a blanket cylinder that rolls into contact with the plate cylinder,
Alternatively, in a rotary printing press that has a plurality of printing units in which the impression cylinder is in direct contact with the plate cylinder and is driven by mutually meshing gears fixed to the shaft of each cylinder, the impression cylinder of each printing unit is The gear fixed to the shaft of the impression cylinder is movable in the direction of the meshing pressure angle, and the traveling path of the paper with respect to the impression cylinder is wrapped around the impression cylinder over approximately 1/2 of its circumference. The guide rollers are arranged so that both paths in the winding direction are substantially perpendicular to the above-mentioned moving direction of the impression cylinder, and the impression cylinders in each printing unit are selectively moved toward and away from each other to sequentially move the impression cylinders toward each other. By printing repeatedly, a printed product is obtained in which one repeat length is longer than the length of the plate cylinder of the printing unit. Further, the impression cylinder is moved in the direction of the meshing angle of the mesh that drives it, and this movement of the impression cylinder is performed without changing the path length of the paper.

The positional relationship between the rotation axis O1 and the axis O2 of the shaft 4a is as follows:
By operating the cylinder device 14 in one direction, for example in the shortening direction, the axial center O2 of the shaft 4a is separated from the axial center O3 of the shaft 3a of the blanket body 3, and by operating the cylinder device 14 in the extending direction, both shafts 3a, 4a are separated. The gears 9 and 10, which are fixed to each other, are set in a position where they mesh normally. The direction of movement of the shaft 3a is in the direction of the meshing pressure angle α of the gears 9 and 10.

なる位置に配設されている。 On the other hand, the guide rollers 5 and 6 are used to regulate the travel path of the paper 15 relative to the impression cylinder 4, and these guide rollers 5 and 6 are arranged so that the paper 15 passes approximately half the circumference of the impression cylinder 4. As if wrapped around me,
Further, both paths in the winding direction are arranged at a position such that they extend in a direction perpendicular to the moving direction of the impression cylinder 4 (the direction of the meshing pressure angle α).

動が休止される。 Meanwhile, during the printing operation, each printing unit 1a,
When the cylinder devices 14 of 1b and 1c are shortened,
The shaft 4a of the impression cylinder 4 moves in a direction away from the shaft 3a of the blanket cylinder 3, the impression cylinder 4 is separated from the blanket cylinder 3, and the printing operation in this printing unit is stopped.

変化されない。 At this time, the shaft 4a of the impression cylinder 4 is separated in the direction of the meshing pressure angle α of the driving gears 9 and 10, and both paths of the paper 15 wound around the impression cylinder 4 are moved by the movement of the impression cylinder 4. Due to the extension in the direction perpendicular to the direction, the path length of the paper 15 is not changed by the movement of the impression cylinder 4.

刷ユニツトにおいても同様である。 Among the printing units 1a, 1b, 1c, and 1d, the first printing unit 1a prints over the range A. That is, the impression cylinder 4 is brought into pressure contact with the blanket cylinder 3 only while printing the above-mentioned printing area A, and is separated from the blanket cylinder 3 in other areas. This operation is similar in other printing units as well.
第２の印刷ユニツト１ｂでは、上記第１の印刷

＋Ｄによつて１リピート長となつている。従つて
１リピート長は2CLの長さになつている。 The printing lengths of the printing ranges A and D of each of the printing units 1a to 1d are shorter than the circumferential length CL of the plate cylinder 2, and in this embodiment,
A+B=C+D=1CL, so A+B+C
+D makes it one repeat length. Therefore, one repeat length is 2CL.

リピート長さの印刷物が得られる。 By the above printing method, it is possible to obtain a printed matter with a printing length twice as long as the circumferential length CL of the plate cylinder 2 in one repeat. The printing length of one repeat at this time is the maximum length of the sum of the circumferential lengths CL of each plate cylinder 2 of the printing unit, and within this length range, printed matter of any repeat length can be obtained.
