Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a turn bar angle adjustment device provided in a folding machine of a rotary printing press.

<Prior Art> A folding machine of a rotary printing press is equipped with a drag device that vertically cuts printed paper, which is a dry and cooled web, to regulate the feeding direction.

The drag device has a turn t for changing the traveling direction of the printing paper to the horizontal direction, dividing the feeding path, or stacking the printing paper.
3- is provided.

FIG. 9 is a schematic perspective view of a drag device in a folding machine of a rotary printing press.

The dried and cooled printing paper 1 is conveyed by a rotating drag roller 2. The printing paper 1 is vertically cut by a slitter 3, and its direction is regulated by a driven rotating guide roller 4, and one printing paper 1a is sent to a gear-side former (not shown) and folded parallel to the flow direction. . The other printing paper 1b
After the direction of the paper is regulated by the guide roller 4, the feeding direction is reversed by the second guide roller 5 which rotates as a result of rotation, and the direction of movement is changed to the side opposite to the gear by the turn bar 6, and the paper is sent to a folding means (not shown).

When the turn bar 6 rotates, a force due to lateral displacement acts on the printing 'M11, so that the turn bar 6 cannot rotate. Therefore, in order to reduce friction with the printing paper 1, a large number of holes are provided on the surface around which the printing paper 1 is wrapped, and air is blown out from inside to float the printing paper on an air film. .

<Problems to be Solved by the Invention> However, when changing the printing specifications, the direction in which the printing paper 1b travels may be changed, or the front side and the back side of the printing paper may be changed. In some cases, the printing paper 1b may be fed by switching between the printing paper 1b and the printing paper 1b.

In this case, the installation angle of the turn bar 6 must be changed, but in order to change the angle of the turn bar 6, the turn bar 6 attached to the broken bracket must be removed from the folding machine and re-installed to have the desired angle. The installation had to be fixed or replaced with another turn bar.

Therefore, a large amount of labor is required to replace the turn bar, and there is a problem in that work efficiency is significantly reduced.

<Means for Solving the Problems> The turn bar angle adjusting device according to the present invention is provided in a turn bar that is attached to a folding machine via an attachment member and that wraps around a web conveyed from the upstream side to change the traveling direction of the web. , the turn bar is rotatably attached to the folding machine via the rotation shaft so that a rotation shaft formed on the attachment member of the turn bar becomes the rotation center of the turn bar, and The mounting angle of the web is changed by rotation of the turn bar to adjust the traveling direction of the web.
