Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a data setting device for controlling a folding machine in a printing press. The present invention relates to a data setting device for controlling a folding machine in a printing press, which facilitates presetting of a folding machine by controlling the position of a correction roller in the folding machine based on the position control data.

[Background of the Invention] For example, there is an offset rotary printing press as a printing press that can print a large amount of printed materials such as magazines in a short period of time. In this rotary offset printing machine, after the web is conveyed to the printing section, it is passed between a plate cylinder and a pressure plate to print characters, etc., and then it is dried and cooled and introduced into a folding machine to make the web into specifications. It is configured to be shaped into a suitable form and transported.

Here, the web on which characters and the like are printed is usually adjusted in the horizontal or vertical direction at a folding introduction section at the front stage of the folding machine in accordance with printing conditions such as paper width and bookbinding specifications. The lateral position adjustment is performed using, for example, a turn bar which is a correction roller arranged obliquely with respect to the web conveyance direction.

That is, the turn bar is configured to be displaceable along the web conveyance direction (vertical direction), and the web conveyed via this turn bar is laterally displaced in accordance with the displacement of the turn bar, and its position can be adjusted. It will be done. In this case, displacing the turn bar changes the path length of the web introduced into the folding machine. Therefore, a correction roller that has an axis perpendicular to the web conveyance direction and is movable in the conveyance direction (vertical direction) is installed in the crease section, and by displacing this correction roller, the web The route length is being adjusted.

Incidentally, recently, the production of a wide variety of printed matter in small quantities has been increasing, and in order to meet this demand, it is desired to speed up the adjustment work of the correction roller including the turn bar in the folding machine.

In this case, the correction roller has conventionally been adjusted manually by a skilled worker or by remote control using a control panel. However, this adjustment method not only requires considerable skill, but also has the disadvantage that it is impossible to tell whether the adjustment is correct or not unless you print it out. Therefore,
This adjustment process takes a long time, and also requires a lot of paper, ink,
It has been pointed out that there is a disadvantage that a large amount of printing materials such as gas are wasted.

On the other hand, as a way to solve such problems, paper width,
It is configured to store position data of the correction roller when printing according to printing conditions such as bookbinding specifications, and to preset the correction roller based on the position data when printing is performed under the same printing conditions as this printing condition. There is something I did.

In this case, it is possible to perform the folding machine adjustment work at high speed using the position data for the printing conditions where the correction roller position data is stored, but when printing the printed matter under new printing conditions Therefore, the correction roller cannot be preset, and as in the case of the conventional example described above, the adjustment work takes a long time and a large amount of printing material is wasted.

[Object of the Invention] The present invention has been made in order to overcome the above-mentioned disadvantages, and includes setting in advance position control data of the correction roller for various printing conditions such as the paper width of printed matter and bookbinding specifications. By selecting the position control data and controlling the position of the correction roller according to the printing conditions of the printed matter, the correction roller can be quickly adjusted according to various specifications of the printed matter, and furthermore, printing materials are not wasted. An object of the present invention is to provide a data setting device for controlling a folding machine in a printing press.
