Description

[Detailed description of the invention] a. Field of industrial application This invention is a rotary press, especially a paper roll press for newspapers, which is capable of increasing the number of newspaper sections (volumes) published per run. Relating to a section folding device.

b. Prior art Currently, the standard format for publishing newspapers is 2 to 8 sheets of paper, each with 4 pages, stacked on top of each other and folded in half to form a single volume. A state is called one section. In Japan, newspapers are sometimes published in separate volumes with feature articles and other articles added in a separate section that is separate from the above section, and the number of pages is numbered serially. Currently, most of them are only 2 sections, with newspapers published on New Year's Day being published in 3 sections. In America, it is more popular than in Japan.

However, as is well known, the amount of information is becoming extremely diverse and increasing day by day, and the number of pages of newspapers being published is increasing. There are some fields where it is more appropriate to separate and compile information from the perspective of transmitting information, and readers may find it easier to preserve the material if special articles are published in separate sections, or if they are published in a single section. A separate book with multiple sections has the advantage of being readable by multiple people at the same time.Furthermore, in the transportation and distribution process, the single section with multiple pages becomes bulky when folded into quarters, so it is difficult to use multiple sections. The section-separated method has advantages such as the fact that newspapers are not damaged.

By the way, as shown in FIG. 15, multi-section folding is not impossible even with the conventional two-stage former folding machines A, B, C, and D arranged one above the other in pairs. However, there are limits to this, and it is difficult to fully support a newspaper publishing system based on a multi-section volume system. This is because, even with the above-mentioned conventional machine, (a) the ability to fold and discharge sheets from 1 section to 4 sections is capable of straight folding (with a production capacity of 2 copies per rotation of the printing cylinder). However, (b) among the multiple sections, it is mechanically impossible to fold the odd sections of 5 and 7, and (c) the even sections of 6 and 8 are folded by collect folds (also known as storage folds) in the folding drum. (that is, the production capacity is 1 part per rotation of the printing cylinder), but the production capacity is halved to 1/2 of the straight folding.

(d) Furthermore, in the case of collect folding, for example, in the case of 8 section folding, it is not possible to freely set the number of newspaper pages that make up each section; The number of newspaper pages in corresponding sections 4 and 8 is constrained to be the same, and it is mechanically impossible to make them different.

c. Problems that the invention aims to solve The first purpose of this invention is that as newspaper publishing formats become more diverse and the amount of information increases, in the near future the format of newspaper publication will change from one-section, multi-page format to multi-section, multi-page format. It is an object of the present invention to provide a multi-section folding device capable of quickly and reliably responding to unprecedented changes in shape.

The second purpose of this invention is to quickly and reliably respond to the changes described above by creating a multi-purpose folding machine that can be easily and inexpensively met by simple modification and expansion work that can make full use of the existing form folding machine. An object of the present invention is to provide a section folding device.

The third purpose of this invention is to create a device that allows all desired multi-section folding to be achieved by straight folding, and that enables high-speed multi-section folding without the risk of hindering production capacity in the slightest. It is to provide.

A fourth object of this invention is to provide a multi-section folding device that can be uniformly implemented regardless of whether the number of sections is odd or even.

A fifth object of this invention is to provide a multi-section folding device that has the flexibility to arbitrarily set the number of newspaper pages constituting each section.

d Means for solving the problem The configuration of this invention is such that the upper and lower two sets of formers and/or the two lower sets of formers of the upper and lower two-stage former folding machine are arranged one above the other in pairs. There are two sets of formers, and the outer two sets of formers are arranged side by side with a slight interval at the same height on both sides of the two sets of formers to form a quadruple former. Two sets of turn bar mechanisms are arranged so that each half-cut running paper obtained by dividing the running paper directed toward .

e Effect Of course, the same applies even if all parts are newly installed, but it is also possible to fully utilize the existing two-stage upper and lower former folding machine that has been conventionally used. In that case, the upper stage and Alternatively, one set of formers is added adjacent to each side of each of the two sets of formers in the lower row, and in any case, the upper four sets +
Since 6 to 8 sets of former folding machines are formed, each consisting of 2 lower sets, 2 upper sets + 4 lower sets, or 4 sets each of upper and lower folders, the production speed is slightly reduced when folding newspapers into 6 to 8 sections at once. This makes it possible to issue documents with straight folds without folding.

On the other hand, a turn bar mechanism is provided so that both of the half-cut running sheets to be introduced into the middle two sets of four formers out of the four sets adjacent to each other can be redirected to any of the other three running lanes. Since they are arranged in relation to each other, they not only have the freedom to publish not only even-numbered sections but also odd-numbered section newspapers, but also have the freedom to arbitrarily set the number of newspaper pages that make up each section. Users will be able to freely edit newspapers without being subject to any restrictions on the number of pages or the number of pages.

f Example 1 The first example (Figs. 1 to 11) is a conventional two-stage upper and lower former folding machine A, B, C, and D. The second embodiment (Fig. 12) shows a maximum of six section folding apparatus in which formers G and H are arranged in parallel.
The third embodiment (Figs. 13 and 14) shows a maximum of 6 section folding device in which one set of formers I and J are arranged in parallel on both sides of the former. Two sets of upper and lower rows of D, one set each of formers G, H, I, J on both sides of all of A, B and C, D
This shows a maximum of 8 section folding device with 8 sections arranged side by side.

The outer two groups of formers G, H or I, J are junior high school students.
A set of formers A, B or C, D are arranged in parallel at the same height on both sides, and are combined to form four consecutive formers at the same level. However, it is necessary to arrange them side by side with a small distance l between them. The reason for this is that if the running lanes a and b of the running paper towards the middle 2 sets of formers are too close to the running lanes g and h of the running paper towards the outer 2 sets of formers, the running papers will interfere with each other. On the other hand, the drag roll 20, the guide roll 21, which is lengthened to correspond to the full width of the four-former,
This is because, in order to prevent the adjustment roll 22 from bending, it is preferable in terms of strength to support it with the existing side frames 25 and 26 in addition to the additional side frames 23 and 24 that support them. For example, when using the longest roll, the effective length of the drag roll 20, guide roll 21, and adjustment roll 22 is at least 2 times the maximum paper width of the full-width running paper W.
The wide drag roll 20 is divided into three parts, one for the maximum width at the center and one for the half width on the left and right sides, as shown in the figure. Sometimes it is installed in a state.

Now, the full-width running paper W consisting of a plurality of sheets discharged after printing has been completed by a plurality of printing devices (not shown) is passed through the first drag roll DR, which has a slitter knife SK in the center. Then, after being divided into two parts in the longitudinal direction and cut into half-width running paper W/2, W/2, if the paper runs straight in that state, the four continuous forms A, B, G, Forms A and B for middle 2 groups of H
The vehicle is caused to travel along driving lanes a and b toward the destination.

However, the above, i.e., Fig. 4 A, B
As shown in , when running the running paper straight, it is better to half-cut the full-width running paper on the drag roll 20 directly above the 4-former than to cut the full-width running paper in half on the first drag roll DR to avoid interference during running. To avoid any risk of trouble, in that case, half-slice the paper W with the slitter knife 20a on the drag roll 20, and in other cases, cut the full-width running paper W with the slitter knife SK on the first drag roll DR. Cut in half.

As is well known, a dedicated drag roll 27 is also provided directly above the upper two sets of formers D and C.

Next, while heading from the first drag roll DR to the drag roll 20 on the four-former, the running lanes of each half-cut running paper W/2, W/2 are set outside of the middle two a and b, and a new outer two. Books g and h are added, making a total of four. In the present invention, in order to increase the number of sections and, going one step further, to freely increase or decrease the setting of the number of newspaper pages in each section, the half-cut running paper W/2 running on one running lane a is It is possible to change the course of all or part of the half-cut paper W/2 running on the other lane b to any of the other three lanes b, g, or h. Turn bars are arranged on each of the travel lanes so that the vehicle can change course to any of lanes a, g, and h.

In Figure 2, the middle two driving lanes a and b
On the top, turn bars 1, 5 and 2, 4 intersecting each other in an X shape are arranged on each lane, while
Turn bars 3 and 6 for carrying in are placed on the outer two travel lanes g and h, respectively, and the installation level of the six turn bars in total is parallel to each other, for example, one turn bar is parallel to the other. The three parallel wires 1, 2, and 3 facing the other side are arranged in the lower row.

Furthermore, even among the three turn bars that are roughly divided into the same upper and lower rows, in detail, the turn bars (1 for the upper row and 4 for the lower row) dedicated to carrying out that are installed in the lane before changing direction are as follows: Each turn bar (3 in the upper stage, 6 in the lower stage) dedicated to carry-in provided in the lane after changing the course is always attached below by a height corresponding to the diameter of the bar.

Therefore, the turn bar located in the middle of each of the three turn bars (2 in the upper row and 5 in the lower row) is sometimes used, for example, in the case shown in FIGS. Turn bar 2 for
a or 5a, respectively, at the same height as the turn bar 1 or 4, respectively, while in other cases, for example, as shown in Figures 8 to 9, the turn bar installed in the lane after the change of course is installed at the same height as the turn bar 1 or 4 respectively. In some cases, the turn bar 2 or 5 is installed at the same height as the turn bar 3 or 6, which is used only for carrying in, and in other cases, for example,
As shown in FIG. 1, when a running paper that is changing course passes through the intermediate turn bars 2 and 5, they may be removed so as not to interfere with the running of the paper.

Regarding the increase in the number of sections of newspapers published and changes in the number of pages in each section,
Specific examples thereof are shown below with reference to FIGS. 4 to 11.

First, in FIGS. 4A and 4B, the full-width running paper W is only divided into two by the slitter knife 20a and introduced into the middle two sets of formers A and B (or C and D), so the number of sections is also small. The number of pages does not change at all.

Next, in FIGS. 5A and 5B, the full-width running paper W is divided into two by the slitter knife SK, and in FIG. At the same time, the half-cut running paper W/2 on the right side changes course to the outside lane via turn bars 5a and 6 and is introduced into the outside formers G, J. Introduced into I.

Figure 6 A, B, Figure 7 A, B, Figure 10 A, B
11A and 11B show an embodiment in which any running paper on the inside side is changed to any one of the outside lanes.

Figures 8A, B and 9A, B show a modification in which one of the middle running sheets is superimposed on the other running paper of the middle side.

g Effects of the invention The conventional two-stage upper and lower former folding machine (No. 15)
The performance of the former folding machine (Fig. 14) and the former folding machine (Fig. 14) capable of folding 8 sections according to the present invention will be explained below in comparison.

In the former case, it is possible to publish newspapers with 1 to 4 sections by straight folding, but not only is it impossible to fold odd numbers beyond that, that is, 5 and 7 section folds, but it is also impossible to fold even numbers, that is, 6 and 8 section folds. Even if it is possible to carry out collect folding using the folding cylinder 28, the production capacity will be halved, and the number of pages in the front and rear sections corresponding to the collect folding will naturally be limited to the same number.

On the other hand, in the latter according to the present invention, newspapers with sections 1 to 8 can be published regardless of whether they are odd or even numbers.
All of this is achieved quickly with straight folding, and
Furthermore, the number of newspaper pages constituting each section can be increased or decreased as desired by the turn bar mechanisms 1, 2, 3, 4, 5, and 6, which change the course of the running paper.

Furthermore, the present invention can realize the above-mentioned multi-section folding simply and inexpensively by making full use of the existing form folding machine and modifying and expanding it, if necessary.
