After the paper has been threaded by the automatic paper threading device described on pages 62 to 64 (Published by the Japan Newspaper Association (Japan Newspaper Association) on March 31, 2018), regarding the paper threading route after the branch point where it branches into various paper threading routes, The paper guide means, such as guide rollers, drag rollers, and turning bars, are selected exclusively based on the worker's memory, and the paper is threaded in sequence.

[Problem to be solved by the invention]

In the conventional technology, the paper threading route is not displayed for each paper guide means such as guide rollers, drag rollers, and turning bars. Selection of means The threading operation is carried out solely based on the memory of the operator. Therefore, due to a mistake in the worker's memory, the operator may make a mistake in the paper threading route and have to thread the paper again, resulting in a huge waste of time. To deal with this, a dedicated worker for paper threading is required.

[Means to solve the problem]

A paper threading route display device for a rotary press according to the present invention includes a light-emitting display device provided corresponding to each paper guide means through which a web-like paper is threaded sequentially from a paper feed section toward a downstream side, and a light-emitting display device provided corresponding to each paper guide means, a light emission control device connected to the display device and controlling the operation of the light emission display device, the light emission control device comprising:
The paper threading route determined for each processing format of web-like paper by the rotary press is memorized, and the light emitting display device is operated in accordance with the specification of the processing format.

[For production]

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

At this time, the sheets are threaded through various routes in order to variously change the order of stacking in the folding unit. Furthermore, in the guide roller, there are cases in which the guided paper is wound around the guide roller in a clockwise direction and cases in which it is wound in a counterclockwise direction.

Therefore, the user operates the light emission control device to specify and input the processing format for the paper into the light emission control device. Then.

The light emission control device causes the light emitting display devices associated with the paper guide means that correspond to a designated paper threading route among the predetermined paper threading routes stored for each processing style to emit light all at once.

The operator selects the route for threading the paper according to the light-emitting display, and threading the paper is performed.

〔Example〕

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

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

The rotary press includes one single-sided multicolor printing unit ST, two-sided printing units P, P..., and a folding unit F, and is further provided with a rail frame part RF including a nest structure NS, and each of the two-sided printing units P. is equipped with a paper feed section (not shown).

For the convenience of checking the working tool, it is preferable that at least the first light emitting section 11 emits blinking light.

It is not necessary that all paper guide means include these three types of light emitting parts. For example, since the guide roller GR19 has a predetermined winding direction of the paper and a downstream guide destination, it is sufficient that the guide roller GR19 is provided with only the first light emitting part ti that indicates the paper guide means.

Further, a fourth light emitting section 14 may be provided to provide upstream guiding light for the paper to be guided to the paper guide means.
