るようにしている。Here, the paper cut at the opposite contact points between the cutting cylinder 13 and the folding cylinder 14 is conveyed to the gripping cylinder 15 along the lower half peripheral surface of the folding cylinder 14, so the paper is cut in this process. It is necessary to provide some kind of paper guiding device that presses the paper against the peripheral surface of the folding cylinder 14 so that it does not hang down. FIG. 6 and FIG. 7 are schematic front views of a conventional paper guide device, respectively.
A brush 20 is applied as shown in FIG. 6, or a belt 22 stretched by belt rollers 21 is wound as shown in FIG. That is, the paper is pressed against the folding cylinder 14 by the brush 20 or the belt 22 so that the paper comes into close contact with the peripheral surface of the folding cylinder 14.
＜考案が解決しようとする問題点＞ ところが、従来の紙案内装置において、ブラシ20を用い

行えないという問題点もあった。<Problems to be solved by the invention> However, in the conventional paper guide device that uses the brush 20, the folding accuracy changes depending on the change of the paper thickness and the machine speed, and therefore the brush pressure is adjusted each time. However, there is a problem that the durability is poor.
On the other hand, in the case where the belt 22 is used, the belt roller 21 cannot be arranged in the vicinity of the contact portion between the folding cylinder 14 and the gripping cylinder 15 due to the installation space. There was a problem that the winding range was restricted and the guidance was insufficient. Further, although the traveling direction of the paper changes when it moves from the folding cylinder 14 to the gripping cylinder 15, since the traveling direction of the paper is limited only to the traveling direction of the belt 22 by the guide by the belt 22, the paper traveling direction is limited. There was also a problem that the transfer to the body 15 could not be performed smoothly.

ことでベルト32の張力を調節できるようになっている。The cut paper conveyed along the peripheral surface of the lower half of the folding cylinder 14 is half-folded and moves to the gripper cylinder 15.However, in this half-folding operation of the paper, the speed of the paper changes, and after half-folding. There is a change in the traveling direction of the paper. Therefore, before the half-folding operation of the paper, there is no change in the speed and the moving direction of the paper.
With the brush 33, the paper is flexibly folded by the brush 33 in the section b so that the paper can be surely brought into close contact with the peripheral surface of the folding cylinder 14 by 32 and the speed change and the change in the traveling direction of the paper can be absorbed after the half folding of the paper. It is pressed against the circumference of 14. That is, as shown in FIGS. 1 and 2, the paper guide device 30 is held by two supporting shafts 35 and 36 which are suspended and fixed to the frame 34. The belt 32 has an endless shape, and a belt roller 38 pivotally supported by a lever 37 mounted on a support shaft 35 and a belt roller 41 pivotally supported by two levers 39, 40 mounted on the support shaft 36. ,
42 and a plurality of sets are arranged in the axial direction of the folding cylinder 14 to form a guide device by the belt 32. These belts 32 are positioned so that a part of the belt 32 stretched between the belt rollers 38 and 42 in the section a is wound around the folding cylinder 14 as described above. Also, each lever 37,3
9 and 40 are attached to the support shafts 35 and 36 respectively so that the mounting angles can be adjusted. By changing the mounting angles of the levers 37 and 40, the winding range of the belt 32 around the folding cylinder 14 can be changed. In addition, the tension of the belt 32 can be adjusted by changing the mounting angle of the lever 41.

いる。On the other hand, a plurality of brackets 43 for fixing the brush 33 between the adjacent levers 37 are attached to the support shaft 35 so that the attachment angle can be adjusted.
A brush 33 is fixed to each of them to form a guide device by the brush 33 (note that the brush 33 is not shown in FIG. 2). These brushes 33 are positioned so that the tips of their bristles come into contact with the peripheral surface of the folding cylinder 14 in the aforementioned section b, and the contact pressure of the brushes 33 can be changed by changing the mounting angle of the bracket 43. You can do it.

的な速度変化が発生する。Next, the operation of the present apparatus will be described with reference to FIGS. 3 and 4. As shown in FIG. 3, initially, the cut paper 44 is pressed against the folding cylinder 14 by the belt 32, and the belt 32 is rubbed by the friction.
The paper 44 circulates at the same speed as the peripheral speed of the folding cylinder 14 so that the paper 44 is conveyed in close contact with the folding cylinder 14. Then, as shown in FIG. 4, when the folding cylinder 14 and the gripping cylinder 15 rotate to the position where the insertion blade 18 and the gripping plate 19 face each other, the trailing edge of the paper 44 exceeds the position P and the second half of the paper 44 is reached. Is mainly pressed against the folding cylinder 14 by the brush 33 and guided. Here, the central portion of the paper 44 is held by the holding plate 19 by the protrusion of the insertion blade 18 and half-folded.At the moment of being folded by the holding plate 19, the paper 44 has an instantaneous speed change. Occurs.

ことでその速度変化に対応することが可能となる。That is, in order to fold the paper 44 in half, when the central portion of the paper 44 in the transport direction is located at the contact point between the folding cylinder 14 and the gripping cylinder 15, the insertion blade 18 pushes the paper 44 to the holding plate 19 side. Push in. At this time, the trailing edge half of the paper 44 pressed against the peripheral surface of the folding cylinder 14 by the brush 33 is moved in the cylinder direction at a speed higher than the conveying speed by the folding cylinder 14. But,
Since the half of the paper 44 on the paper tail side is pressed against the peripheral surface of the folding cylinder 14 by the brush 33, the flexibility of the bristles of the brush 33 absorbs the impact on the paper 44 caused by the change in speed. After that, the paper 44 moves to the holding cylinder 15 side,
Although the paper 44 changes its traveling direction in a direction away from the folding cylinder 14, the speed change in this case is also absorbed by the flexibility of the brush 33, and the paper 44 is stably guided. Ie brush
In the section b where 33 is arranged, the front half of the paper 44 is the folding cylinder.
While the latter half of the sheet tends to separate from the folding cylinder 14 while closely contacting with 14, it is possible to cope with the speed change by guiding the section with the elastic brush 33.

However, in addition to this, the lever 37 and the bracket 43 are supported by different support shafts. It is also possible, and in this case each lever 37,
By attaching the support shafts that support the brackets 43 to the frame so that the rotation is adjustable, the winding range of all the belts 32 and the contact pressure of all the brushes 33 can be adjusted simultaneously by the rotation of the support shafts. Becomes

でも適用することができる。Further, in the present embodiment, since the cutting length of the paper 44 corresponds to the semicircular length of the folding cylinder 14, the phase of the folding cylinder 14 from the contact point of the folding cylinder 14 and the gripping cylinder 15 to the position P. The angle is approximately 90 degrees, but for example, when the cutting length of the paper 44 corresponds to the 1/4 circumference of the folding cylinder 14, that is, when four cutting blades 16 are provided on the peripheral surface of the cylinder. The phase angle of the folding cylinder 14 is approximately 45 degrees from the contact point of the two cylinders 14 and 15 to the position P. Furthermore, in the above-mentioned embodiment,
Although the folding machine in which the gripping cylinder 15, the folding cylinder 14, and the cutting cylinder 16 are adjacently arranged in this order has been described, the paper guide device of the folding machine of the present invention is not limited to such a cylinder arrangement. The present invention can be applied not only to a gripping cylinder, a folding cylinder, and a cutting cylinder, but also to such a cylinder.

れにより折精度の向上が図れる。<Effects of the Invention> As described above in detail with reference to the embodiments, according to the present invention, a guide device using a belt is provided on the upstream side in the transport direction in which the paper traveling direction is always along the peripheral surface of the first cylinder. Since the guide device by the brush is provided on the downstream side in the conveying direction where the traveling speed and direction of the paper change, the belt surely adheres the paper to the first cylinder peripheral surface, while the brush elastically moves the first cylinder. The change in the speed of the paper and the change in the direction of travel of the half-folded paper are absorbed by pressing the paper against the peripheral surface, and as a result, the paper can be guided reliably and stably, which leads to the folding accuracy. Can be improved.
