Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a web threading device for a rotary press that prints by passing a web material through a paper threading path from a paper feed section to a printing section to a folding section. It is effective to apply to a rotary press that has a paper threading path that passes through a number of guide rollers including a double-ender device and a bay window device and a turning bar between the paper feeding section and the folding section. The present invention relates to a paper threading device configured to perform paper threading by a paper threading body that moves according to a guide provided along a path.

[Conventional technology]

A conventional web threading device for a rotary press is, for example, an actual flat sheet 1-1036.
The technique disclosed in Japanese Patent Publication No. 47 is known. According to this conventional technique, a pipe-shaped guide rail that has a branch portion and has a notch in the longitudinal direction of the side is laid along a plurality of presumed paper threading paths, and an appropriate guide rail is provided. The driver is provided in the notches formed at intervals,
There is provided a running body which is driven by the driving body and runs in the guide rail in a meandering manner, and has a total length slightly longer than the interval between the cutout portions, and further, a roll installed in the paper feeding portion. Clip that detachably holds the paper connection adapter connected to the tip of the printing paper
It is provided on the traveling body.

[Problems to be Solved by the Invention]

 The above-mentioned conventional technique has the following problems.

The web threading in the rotary press is performed from the upstream side to the downstream side, that is, from the paper feed section to the folding section. At this time, the web material to be threaded is guided by a relatively short running body (called a short running body). Get burned. At this time, since the driving bodies for driving the short-long running bodies are provided at intervals slightly shorter than the length of the short-long running bodies, they are driven by two sets of driving bodies and one set of driving bodies. In some cases, the driving force is not constant,
In addition, since the speed is reduced when passing through a portion with high running resistance, such as due to corners or friction, the running speed of the short-length running body becomes uneven, and as a result, the web paper connected to the short-length running body does not move. The web threading speed becomes uneven, the web material is slackened due to deceleration, and the wrinkles are generated due to the increased speed. In the worst case, a paper break occurs, which causes a great obstacle to the paper threading requiring certainty.

In the case of newspaper printing, for example, with the recent increase in the number of pages and the increase in color printing, a large number of guide rollers and turning bars including a double-ender device and a bay window device are provided in the paper passage path from the paper feed unit to the folding unit. Since it is necessary to increase the number, the paper passage path has become significantly longer than in the past. As a result, as the driving bodies for driving the short-length traveling bodies moving in the guide rails are installed at a slightly shorter interval than the length of the short-length traveling bodies as described above, it is unavoidable to arrange more. It was As described above, providing a large number of driving bodies not only increases the product cost, but also complicates the inside of the narrow rotary press frame, and at the same time, makes it difficult to perform maintenance and inspection work other than normal printing work. There was also a safety issue.

The present invention has been made in view of the above. It is possible to divide a web material paper in the width direction along the longitudinal direction in the middle of the paper threading path and thread each of the divided paper threading paths into separate paper threading paths. In a rotary press capable of performing, at a substantially constant speed, it is possible to smoothly and reliably pass the web material without uneven tension acting on the web material, and since the structure of the device itself is simple, it is possible to prevent failure. An object of the present invention is to provide a paper threading device for a rotary press, which is less likely to occur, easy to maintain and manage, and is also safe.

[Means for Solving the Problems]

In order to achieve the above object, a web threading device for a rotary press according to the present invention divides a web material into a width direction along a longitudinal direction in the middle of a web threading path, and separates each of the divided web threading paths. In a rotary press capable of threading a web material, a paper threading body guide provided along the paper threading path of the web material paper from the paper feed section, and the paper material of the divided web material paper from the vicinity of the position where the web material paper is divided. Other paper threading body guides provided along the threading path, a paper threading body pool portion provided on the downstream side of each of the paper threading body guides, and along each paper threading body guide drawn from the paper threading body pool portion. And at least one paper threading body having a length from the position of the paper threading start point of the paper threading body guide along the longest paper threading path to the paper threading pool portion, Through A paper locking member provided at each one end for locking each web material to be threaded, and at least one downstream side of each paper threading body guide in order to cause each of the paper threading bodies to travel in accordance with the paper threading body guide. And a paper threading member drive section of the paper threading body which is provided on the downstream side of the position where the web material is divided, and the free end of the divided divided web material is made to stand by there. It is configured to have automatic locking means for automatically locking.

Further, it has at least one of the above-mentioned paper feeding section.

Run backwards. Then, the web material is locked to the paper locking member of the paper threading body, and then the paper threading body drive section is operated in the forward direction to move the paper threading body from the upstream side to the downstream side of the paper threading guide. , The web material is threaded along the thread guide. At this time, since the paper threading body drive unit is provided on the downstream side of each paper threading body guide, the paper threading body traveling from the upstream side to the downstream side of the paper threading guide is on the downstream side thereof. The paper threading body is reliably pulled to such an extent that the running speed is not affected even if there is a portion with a large running resistance, such as friction at the corner, due to friction.

Further, when the web material is divided in the width direction and then each of them is threaded through a separate threading path, the following operation is performed.

That is, the paper threading body pooled in the paper threading body pool section is guided by the paper threading body drive section, which operates in reverse, from the downstream side of the paper threading path to the web feed standby position of the paper feeding section on the upstream side. The other threading body pooled in the paper threading body pool section is driven in reverse by the paper threading body drive unit that operates in reverse. Then, the web paper is divided into the width direction and reaches the downstream position of the dividing position to stop and stand by. Then, the web material is locked to the paper locking member of the paper threading body, the paper threading body drive portion is rotated in the forward direction, and the paper threading body is caused to travel from the upstream side to the downstream side of the paper threading body guide to Paper through the paper threading path along the paper threading body guide.

The web material to be threaded is divided in the width direction along the longitudinal direction when passing through a division position for dividing the web material provided in the middle of the paper passage path in the width direction, for example, a working position of a slitter. It One of the divided divided web papers, which is locked to the paper locking member of the paper threading body, is threaded by traveling from the upstream side to the downstream side along the paper threading body guide of the paper threading body. Continues as is. The free end of the other divided web material paper among the divided divided web paper materials is pushed and displaced subsequently by the continuation of the paper threading, and stands by at the downstream of the dividing position where the web material paper is divided in the width direction. It is guided on the paper locking member of the other paper threading body.

When the free end is guided onto the paper locking member of the other paper threading member, the drive unit of the other paper threading member starts forward rotation operation. The guide is started to run from the upstream side to the downstream side, and the automatic locking means is operated to lock the free end of the other divided web material to the locking member of the other paper threading body. Thus, the other divided web material paper is threaded through the paper threading path along the other threading member guide.

In this paper threading, the paper threading body and the other paper threading body travel along the respective paper threading body guides at substantially the same speed from the upstream side to the downstream side.
