印刷が正確に行われる。Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotary copy printing apparatus in which a base paper made in a plate making section is wound around a plate cylinder to perform rotary copy printing. 2. Description of the Related Art In a conventional rotary transcription printing apparatus, a base paper made by a plate making section is gradually fed horizontally by a base paper feed roller, and its leading end is clamped by a clamper of a plate cylinder of the printing section. The master copy that was made into a plate was wrapped around the plate cylinder and printed. Further, the plate making section and the printing section were arranged at positions longer than one plate length. In the above-mentioned prior art, the plate cylinder is connected with the interlocking mechanism such as a cam, and the fluctuation during one rotation is large, and a uniform and accurate ultra-low speed is obtained. Since it is difficult to rotate, uneven rotation occurs, this uneven rotation is transmitted to the plate making section as it is and the plate making quality is deteriorated, and the copied original paper is wound in a loose state on the plate cylinder, causing wrinkles. There was a point. SUMMARY OF THE INVENTION The present invention is intended to solve the above-mentioned problems, and a base paper prepared by a plate making unit is used as a base paper.
It has a clamp part for the feed roller and the base paper discharge roller.
Stop in a rotary transcription printing device that is fed to the plate cylinder.
The base paper discharge roller and the rotating feed roller
The stencil sheet made between the plates is sagged downward, and the specified amount of slack
, Stop the rotation of the base paper feed roller,
Of the base paper sent to the clamp section by the base paper discharge roller.
Rotate the plate cylinder with the leading edge clamped to
Dispense the base paper by applying tension to the base paper by rotating the roller.
Pull out the base paper from the roller, wind it around the plate cylinder, and
Note that the clamp part and the plate-making part are arranged within one plate length.
Sign . An embodiment shown in FIG. 1 will be described below. The length between the plate making unit 20 and the plate cylinder 21 of the printing unit should be within one plate length, the raw paper feed roller 22 and the raw paper discharge roller 23 having a one-way clutch are arranged in the raw paper feed path, and the center of the raw paper feed roller 22 is The base paper from the plate making section is arranged so as to be fed obliquely downward with the connecting direction directed downward from the direction perpendicular to the horizontal direction, and one end is pivotally attached to the pin 24 between the base paper feed roller 22 and the base paper discharge roller 23, An open / close guide plate 25 is provided so as to be rotatable. Reference numeral 26 is a clamp portion of the plate cylinder 21, 27 is a clamp detection sensor for detecting that the front end of the base paper 28 is inserted and clamped in the clamp portion 26, and a clutch (which is connected to the base paper discharge roller 23 by the detection of the clamp detection sensor 27 ( (Not shown) is cut off and the base paper discharge roller 23 is stopped. 29 is a base paper drive motor. By receiving the output of the detection means, the driving of the base paper discharge roller 23 is stopped, and the drive of the base paper feed roller 22 is continued for a predetermined time, so that the slack of the base paper is caused between the base paper discharge roller 23 and the base paper feed roller 22. After the predetermined time has elapsed, the plate cylinder 21 is rotated, the base paper discharge roller 23 having the one-way clutch is loosely rotated, and the control means (not shown) winds the loose base paper. Next, the operation of the embodiment of the present invention will be described. After the stencil 28 is made in the stencil making section 20, it is sent to the stencil feed roller 22 and proceeds further. At this time, the open / close guide plate 25 is closed at the horizontal position indicated by the solid line. Base paper 28
Passes over the open / close guide plate 25 and the base paper discharge roller 2
The tip is inserted and clamped in the clamp portion 26 by 3.
This is detected by the clamp detection sensor 27, a clutch (not shown) connected to the raw paper discharge roller 23 is disengaged, and the raw paper discharge roller 23 stops. At the same time, the opening / closing guide plate 25 is opened to the lower two-dot chain line position by a solenoid or the like. When the base paper feed roller 22 is driven for a predetermined time in this state, the base paper 28 is fed obliquely downward by the base paper feed roller 22 facing obliquely downward and forms a slack downward as indicated by a chain double-dashed line. When the plate making for one plate length is completed after the lapse of a predetermined time, the base paper drive motor 29 is stopped, and the rotation of the base paper feed roller 22 is stopped. In this state, the plate cylinder 21 rotates in the arrow direction with the front end of the base paper 28 clamped by the clamp portion 26. At this time, the stopped base paper discharge roller 23 is adapted to apply a tension to the base paper by the built-in one-way clutch so as to loosen and rotate in the base paper transfer direction. Then, it is smoothly pulled out from the base paper discharge roller 23 and wound around the plate cylinder 21 to perform printing for one plate length. According to the present invention , the plate made by the plate making section
Clamp the paper with the base paper feed roller and the base paper discharge roller
In a rotary transcription printing device that is fed to a plate cylinder that has
The paper feed roller that has stopped and the feeding roller that is rotating.
Slacken the plate made from the plate with the roller
When the amount of slack is reached, rotate the base paper feed roller
Stop and send to the clamp section by the above-mentioned base paper discharge roller
Rotate the plate cylinder with the tip of the base paper
Tension is applied to the base paper by the rotation of the base paper discharge roller.
And pulling out the base paper from the base paper discharge roller and winding it around the plate cylinder
And place the clamp part and the plate-making part within one plate length.
Therefore, the entire device can be downsized in the direction of feeding the base paper ,
Also because wound thin sheet loose on the plate cylinder pull provided notwithstanding et tension printing regardless wrinkled thin sheet wound around the plate cylinder is accurately performed.
