Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a rotary press that uses web-shaped paper, and is provided with a large number of paper-paper guiding means such as guide rollers, drag rollers and turning bars for guiding the paper. The present invention also relates to a paper threading route display device which is provided at a portion for changing the guide route of the material sheet for each processing format of the material sheet, for example, a portion such as a rail frame portion.

[Conventional technology]

In a rotary press, for example, as shown in Japanese Patent Application Laid-Open No. 58-113063 and Japanese Utility Model Publication No. 61-13478, the guide route is changed for each processing format of the material, and the guide used each time. It is known to change the rollers, or to include the turning bars, and to change the direction in which the paper stock is wound. In addition, the number of types of printing units (multicolor printing unit, single color printing unit) that make up a rotary press has increased, and the arrangement and combination of folding units have become complicated in recent years. To this end, for example, a so-called nest structure for guiding the paper by changing the traveling direction of the paper is provided by appropriately providing multi-tiered paper guide means such as a turning bar, a drag roller, and a turning bar as schematically shown by NS in FIG. Various paper threading routes are set by the use.

Then, in the prior art, a known automatic paper threading means, for example, "newspaper printing / printed edition revised version" (October 1980)
31st, published by The Japan Shimbun Association) After the paper is threaded by the automatic paper threading device described on pages 62 to 64, about the paper threading path after the branching position where the paper is branched into various kinds of paper threading paths, The paper guide means such as a guide roller, a drag roller, and a turning bar are selected and successively passed over one after another by the memory of the operator.

[Problems to be Solved by the Invention]

In the prior art, there is no indication of a paper threading route for each paper guide means such as a guide roller, a drag roller, and a turning bar, and guide paper guides such as a guide roller, a drag roller, and a turning bar in a multi-branched paper threading route. Since the selection and delivery work of the means is performed only by the memory of the operator, the paper passing route may be wrong due to the memory difference of the operator, and the delivery may be repeated again, which wastes a lot of time. To deal with this, a dedicated paper threading worker will be required.

[Means for solving the problem]

A web threading route display device for a rotary press according to the present invention selects web material guiding means such that a web threading route is determined sequentially for each processing format from the paper feeding portion to the downstream side. In a rotary press through which paper is threaded, a light-emitting display device that is provided in the vicinity of each of the paper feed guide means and is provided in the vicinity of the paper feed guide means, and at least the paper feed guide means to which the paper feed guide means is attached can be clearly defined; A light emission control for storing the specified paper threading route and controlling the operation of each light emitting display device associated with each material guide means corresponding to the paper threading route for executing the specified processing format according to the specification of the processing format. And a device for displaying the paper-passing route for carrying out the specified processing format according to the specification of the processing format.

[Action]

In the rotary press, the paper starting from each paper feeding section is guided through a corresponding printing unit by a large number of guide rollers such as guide rollers, drag rollers and turning bars, which are appropriately provided on the rail frame, and folding. They are stacked in a unit, folded, and then discharged.

At that time, in order to variously change the order of superposition in the folding unit, the paper is threaded in various routes. Further, in the guide roller, the guided paper may be wound around the guide roller in the clockwise direction or in the counterclockwise direction.

Therefore, the light emission control device is operated to specify and input the processing format of the paper stock to the light emission control device. Then, the light-emission control device selects the paper-passing route for carrying out the designated process appearance from among the predetermined paper-passing routes stored for each process appearance, and displays the light-emitting display device associated with the corresponding paper guide means. The lights are activated all at once and displayed.

The operator selects the light-emitted display of the paper-sheet guiding means to carry out the paper-threading, and the paper-paper is threaded in the paper-passing route determined for carrying out the specified processing appearance.

〔Example〕

 Embodiments of the present invention will be described with reference to the drawings.

FIG. 3 shows an example of the construction of a rotary press provided with the paper threading route display device according to the present invention.

The rotary press is provided with a single-sided multicolor printing unit ST, a double-sided printing unit P, P ... Group and a folding unit F, and a rail frame part RF including a nest structure NS, and each double-sided printing unit P. A sheet feeding unit (not shown) is provided.
