Description

[Detailed Description of the Invention] [Technical Field of the Invention] ``The present invention is an off-the-shelf technology'''Itli! 1.7: Re〉
etc. mark 1 + 1/1 for improving the printed matter folding device attached to the tlJ stock.

[Technical background of the invention and its problems]

Normally, a printing method such as an offset rotary printing method is equipped with a 1i 1 folding device, for example, as shown in Figure 1, 1 folding device is installed on both sides.
6th page molecules AJ to ``P'' are printed 1liilj times and sent out continuously.As shown in 21nJ, printing page 5 1 is printed 1liilj times and the negative numbers are arranged in alphabetical order, that is, ``A'' to rPJ are One ITjj 1' is subjected to 1 lil + further processing, and is received in a post-processing section such as a book sorting and binding device.

That is, this kind of printed matter folding device includes a first folding means section including a former and a nipping roller section provided on the delivery side of the former, and a cutting/second folding means section including a cutting cylinder, a folding cylinder, and a gripper cylinder. It has a structure in which a means part and a third folding means part consisting of a chopper-shaped folding island are arranged in sequence.

Then, the first folding means section folds the printed matter that is continuously sent out in the running direction, and the second cutting folding means section cuts the printed matter 1 for one printing, and then cuts the printed matter 1 in a direction perpendicular to the running direction. Fold along the direction. Furthermore, this printed matter 1 is fed into a belt-type conveyance system to be conveyed, and a third folding section provided in the middle of the conveyance system performs a final fold in half to process it into a printed book 1'. ing.

In addition, at this time, in the case of a printed book 1' having a relatively large number of sheets, the part corresponding to the final folding edge of the printed book 1' is processed with a zigzag blade to form discontinuous slits 2... In addition to ensuring that a good folded state without bulges is obtained,
Bookbinding glue is well adhered to the processed surface of the negative slit 2 folded inward to ensure bookbinding.

However, conventionally, when performing the zigzag blade processing, processing is performed using a zigzag blade processing means disposed immediately before the second folding means section that performs the final folding in two. In this way, in the past, printed matter was cut from continuous paper and folded several times before being conveyed, so the machining accuracy was subject to large variations due to misalignment of the printed matter during conveyance. There are drawbacks. In addition, since the Ajiro blade machining means is provided completely independently, it is not possible to combine the support mechanism and other functions, resulting in a complicated configuration, which causes high costs and reduced maintainability. I was imitating it.

[Purpose of the invention]

The present invention has been made based on the above circumstances, and its purpose is to provide a method for accurately and reliably processing printed matter with a sharp blade, and also to simplify the configuration, thereby reducing costs and improving maintainability. The present invention is intended to provide a printed matter folding device that can obtain the desired results.

[Summary of the invention]

In order to achieve the above-mentioned object, the present invention includes a former and a nipping roller section provided on the delivery side of the former, so that printed matter continuously delivered from a printing machine is oiled in the running direction. In a printed matter folding device having a folding means for folding, a jig blade processing means is provided on the nipping roller portion of the folding means.

[Embodiments of the Invention] - Hereinafter, the present invention will be explained with reference to one embodiment shown in FIGS. 3 to 11.

First, with reference to FIG. 3 and FIGS. 4(a) to 4(f), the overall configuration of the printed matter folding device and the folding process of the printed matter 1 will be explained. The device includes a first folding means section 3 in the flow direction of the printed matter 1.

Note that 19 is a paper jam detector provided in the middle of the conveying thread path 14.

Next, the configuration of the nipping roller section 9 in which the zigzag blade processing means 10 is incorporated will be explained with reference to FIGS. 5 to 11. As shown in FIG. 5, the nipping roller section 9 is
The first roller unit 9a and the second roller unit arranged after this
Roller: L near) 9h.

The first roller unit 9a includes a nipping roller 2θ,
A nipping roller (
It consists of a paper presser rubber roller) 22.

In addition, the second roller unit 9b constituting the zigzag blade processing means 1o has a zigzag blade receiving nipping roller 23 and a zigzag blade et al. roller 24, as shown in detail in FIGS. 6 and 7. At the same time, Ajiro bladed roller 2
4 has a position adjustment mechanism 25 that allows the position adjustment with respect to the cylindrical blade receiving nipping roller 23. In other words, the roller 24 with a sharp edge is rotatably attached via a support pin 28 to the free end side of an arm 27 which is pivotally supported via a support 1126 on a rotational axis. Arm 2
On the pivot end side of 7, a support protrusion 278 is integrally formed to face the fixed piece 29 whose one end is fixed to the support shaft 26 for a distance tIL.

A compression spring 30 is interposed between the fixed piece 29 and the supporting piece 27a. The support protrusion 27a is always urged downward, that is, so as to be in contact with a stopper 32 attached to the lower end of the adjustment screw 3. Further, the adjustment screw 31 is screwed into a female threaded member 33 integrated with the fixed piece 29, and by turning it in a predetermined direction via the grip portion 31a, the arm 27 is rotated about the support 11] 26. As a result, a roller 24 with a zigzag blade provided on its free end side is displaced. Further, the roller 24 with a zigzag blade holds the zigzag blade 34 between the moving parts 35a, 35a of the roller main body 35, 35, and a plurality of bolts 36...
・It is fixed at .

In addition, the Ajiro blade receiving nipping roller 23 rotates at 1ti.
liI 37, the nipping roller bodies 38a to 38d that have been dismantled by this rotating shaft 37, and the Ajiro blade receivers 39, 39.
It is composed of. As shown in FIG. 8, the above-mentioned Ajiro blade receivers 39, 39 are made of rollers with an elastic member 40 made of urethane or the like stretched around the outer periphery, and are configured so that the cutting edge of the Ajiro blade 34 can bite into them slightly. Blade processing can be performed reliably.

In addition, the Ajiro blade receiver 39.39 is divided into two parts in the radial direction as shown in FIG. It is divided into two in the direction and has a structure that can be attached and detached from the radial direction, making it extremely easy to replace these tubes.

In addition, the nipping roller 2 of the first roller unit) 9a
0 has the same structure as a general nipping roller, as shown in FIGS. 10 and 11.

The printed matter 1 sent out from the printing machine, passed through the former 7 and the pair of lead rollers 8 sequentially, and was folded in half in the running direction as shown in FIG. 4(b) is provided at the latter stage. It is fed into the nipping roller section 9. Then, it is first held between the nipping rollers 20 and 22 of the first roller unit 9a and folded into two securely, and then sent between the roller with a zigzag blade 24 and the nipping roller with a zigzag blade 23 of the 20th roller unit 9b. As a result, as shown in FIG. 4(C), a zigzag blade process is often performed.

At this time, since the printed matter 1 to be processed with a jig blade is in a continuous state before cutting, its running state is extremely stable, and there is no fluctuation in processing accuracy.

In addition, since the nipping roller section 9 is configured to incorporate the jiggling blade processing means 10, it is possible to use it as a support mechanism, etc., compared to the conventional system where it is installed in a completely independent position (6-component do(', , yi, 1゜In addition, in the above-mentioned embodiment, the printed matter 1 that is continuously sent out from the printing machine is processed into two strips, and then one strip is processed with a zigzag blade. However, the present invention is not limited to this; for example, the printed matter 1 continuously sent out from a printing machine may be folded in two or more, and the double-sword blade processing may be performed in a double-edged manner.

In addition, the present invention covers the gist of the present invention to a wide extent! 1
Of course, it is possible to implement various modifications.
