Claims

[Scope of utility model registration request]

A swinging section equipped with a paper feeding guide is driven to swing around a fixed axis by a swinging drive mechanism, and the paper passed through the paper feeding guide is folded in a zigzag pattern by the swinging movement of the swinging section. In the zigzag folding device for a form rotary printing press configured as follows, the swing drive mechanism includes a drive shaft that is rotationally driven by a motor, and converts the rotational motion of the drive shaft into a swinging motion at a constant angle. The device includes a cam mechanism, a swinging main shaft connected to the cam mechanism to perform swinging motion at a constant angle, and a swinging output shaft arranged parallel to the swinging main shaft and operatively connected to the swinging section. death,
A swinging arm is provided on each of the swinging main shaft and the swinging output shaft, projecting in a direction perpendicular to both shafts, and a guide groove passing through the axes of the swinging main shaft and the swinging output shaft, respectively, is provided on both swinging arms. Along with being established,
A slider is engaged with each of these guide grooves so as to be movable along the guide groove, and both sliders are connected so as to be relatively rotatable around a slider connecting shaft parallel to the above-mentioned swing main shaft and swing output shaft. This constitutes a swing transmission mechanism that transmits the swing motion of the swing main shaft to the swing output shaft, and a threaded shaft is attached to one of the two sliders, and its rotation causes the slider to move into the guide groove. A zigzag folding device for a foam rotary printing press, characterized in that the slider is screwed in a fixed state in the axial direction so that the distance between the slider connecting shaft and the swinging main shaft and the swinging output shaft can be changed by moving along the slider. .
