本発明は、電子写真方式を用いる印刷機の用紙
折りたたみ装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a paper folding device for a printing press using an electrophotographic method.
印刷機に用いられる連続用紙において、ミシン
目は常に用紙側面に対し直角に入つているとは限
らず、第１図に示すように用紙１側面に対しα゜曲
がつていることがある。このような用紙が折りた
たまれると、第２図に示すように斜行角β゜傾いた
状態に積み重ねられてしまい、この傾きにより用
紙受台に無理な力が加わり易くなり、用紙ジヤム
等を生じさせる原因となつていた。 In continuous paper used in printing presses, the perforations are not always perpendicular to the side of the paper, but may be bent at α° relative to the side of the paper, as shown in FIG. When such papers are folded, they are stacked at an angle of skew angle β° as shown in Figure 2, and this inclination tends to apply excessive force to the paper holder, resulting in paper jams, etc. It was the cause of this.
本発明は上記の状況に鑑みなされたものであ
り、ミシン目の曲りがある用紙でも限定する必要
がなく使用できる印刷機の用紙折りたたみ装置を
提供することを目的としたものである。 The present invention was made in view of the above-mentioned situation, and it is an object of the present invention to provide a paper folding device for a printing press that can be used without any limitations even on paper with curved perforations.
本発明は、用紙が積み重ね支持される用紙受台

紙の支持を行える用紙受台を得ることができる点
に着目し、用紙、用紙受台の関係を工夫したもの
である。 In the present invention, if a movable base that can move in the width direction of the paper is provided on the paper holder on which the paper is stacked and supported, even when paper with curved perforations is used, the paper can be easily fed skewly. Focusing on the point that it is possible to obtain a paper holder that can follow and stably support the paper, the relationship between the paper and the paper holder has been devised.

方向）のガイド、１１は駆動ローラである。 An embodiment of a paper folding device for a printing press according to the present invention will be described below with reference to FIGS. 3 and 4. 2 is a pressure roller, and 5 is a roller that supports the movable table 3b. The movable table 3b is placed on the lifting table 3a so as to be movable in the width direction of the paper 1 (in the direction of arrow b in FIG. 3) via springs 6, 6 which are elastic members at both ends, and is always supported by the tension of the springs 6, 6. It is attached so that it is in a predetermined position. 7 is a spring support, 8 is a guide in the width direction of the paper 1, 10 is a paddle, 9 is a guide in a direction perpendicular to the width direction of the paper 1 (folding direction), and 11 is a drive roller.

ができる。 The paper 1 is pulled out as shown by the arrow a in FIG.
0 and loaded onto the movable table 3b. Depending on the amount of paper 1 loaded, the lifting table 3a moves up and down along the pillar 4 supported by the printing press main body (the third
(direction of arrow a). When the paper 1 with a bend at the perforation is used, the paper 1 moves diagonally, but the side of the paper 1 hits the guide 8 and is pushed by the force of the paper 1 to move the paper 1 skewly, and the movable table 3b is moved by the spring 6. move against the tension of Therefore, since the paper traveling position and the folding position of the paper 1 do not differ greatly, jams will not occur even if paper with large perforations and curves is used. After taking out the paper 1, the spring 6 returns the movable base 3b to the paper traveling position. The paper folding device of the printing press of this embodiment is configured in this way, and is able to absorb the skew of the paper caused by the bending of the perforations, so that it can be folded without limiting the paper used.
以上記述した如く本発明の印刷機の用紙折りた
たみ装置は、ミシン目の曲りがある用紙でも限定
