Description

[Detailed description of the invention] : Concerning J. Gilfaesa.

Figure 1 shows a side cross section of the conventional general model JJ Lufasa. Figure 2 shows its front view. is the pressure O-rule.4
D-ru with glue. 5 is a doctor bottle, 6 is a glue container, and 7 is a glue. 8 is core paper.

8' is 3 sheets of paper formed in steps. 9 indicates a lining, 1D indicates a single-sided stepped pole sheet, and 11.12 indicates a bearing.

The three sheets of paper 8 are fed to the upper O-roll 1 side, and are caught in the meshing portion of the upper O-1 and lower O-ru 2, forming three sheets of paper 8' formed into a wave shape. Next, the three papers 8' are transferred as the lower O-ru 2 rotates, and @7 in the wA container 6 is transferred to the glued O-ru 4.
After being lifted up and subjected to ml film adjustment in a doctor wheel 5, it is glued to the top of the step of the three sheets 8' by a gluing roll 4.

On the other hand, the 5-inch paper 9 supplied to the pressure roller 6 side and the glued three papers 8' are adhered at the pressing portions of the lower roller 2 and the pressure roller 6 to form a single-sided corrugated board sheet 10. Generally, the upper opening 1 is connected to the lower opening 2, 'f. pressure 0
- Roll 3 applies a linear pressure of 20 to 50 k to the lower roll 2, respectively.
It is pressed at g/an. The former is the pressing force applied to form the three sheets of paper 8 in steps 5 and the latter is the pressing force for applying adhesive force between the stepped eight sheets 8' and the live 9. In addition, the lower O-ru 2 has a tooth-shaped step machined on the outer surface of the roll along with the upper O-ru 1, while the pressure O-ru 3 has a smooth surface. The steps of the O-ru 2 are pressed under pressure and the surface of the O-ru 6 is struck at a high cycle through the paper 8' and the lie 9. With the above structure, the upper 0-ru 1.

) x (dynamic spring constant K between lower O-ru 2 and pressure O-ru 3
) Based on the excitation force, the main component is the number of teeth cycle of the upper and lower rollers 1.2 (number of rotations of the rollers N x number of teeth 2)
The natural vibration value of the roll system is determined by the number of teeth cycle NZ
When the forces match 1, it resonates, especially the three 0-rukes; they vibrate violently. At the time of such resonance, the pressure O-ru 3 and the lower O-ru 2 collide particularly violently, so that a thick colliding load is created between the paper 8' and the liner 9 sandwiched between the O-ru. This may cause the sheet to break.

Depending on the phase state of the vibrations, a phenomenon may occur in which the sheets 8' and 9 are poorly bonded together, and extremely loud noises are generated. The above problems (such as sheet breakage, poor lamination, and loud noise due to 0-ru system resonance) are important issues that need to be solved for single facers, and these problems are becoming even more problematic due to the recent increase in machine speed and deterioration of sheet quality. be.

The present invention has been proposed in view of the above points, and involves interposing a member with lower rigidity than the roller to significantly reduce the excitation force between the lower roller and the pressure roll.

The purpose is to provide a single facer that prevents liner cracking and reduces sound.

The present invention relates to an upper O-roll and a lower O-ru for forming three sheets of paper in stages, a gluing roller for gluing three papers formed in two stages, and a gluing roller that is in contact with the lower roll and glued by the gluing roll. Forming 8 In a single facer equipped with a pressure roller that laminates a live sheet to paper and continuously forms a single-sided corrugated board sheet.

It is characterized in that an annular pressure member having a hollow portion is fitted on the roll surface of the pressure roller, and a liquid, gas, powder, etc. is sealed in the hollow portion.

The most preferred embodiment shown in FIG. 3 will be explained below. In the same figure, 2 is the lower 〇-le, 3m is the pressure O-

Reference numeral 15 indicates a connecting member having a hole inside, and reference numeral 16 indicates a fixing member. Although the lower O-le 2 and the pressure O-le σ are all shown in the same figure, the construction of each member other than these is the same as that of the conventional single facer described above. Then the pressure is 0-
This section describes the rules in detail. The pressure member 13m is the O of the pressure roll.
- It is wrapped over the entire circumferential surface that engages with the lower 0-rule 2 at the loop part. The pressure member 13 & is hollow inside, 1517
It has m.

The hollow portion 17a is in communication with the fluid introduction hole 14 via the connecting member 15. Further, the pressure member 13m is fixed to the pressure 0-ru 3aK by the connecting member 15 and the fixing member 16, and further fixed at the contact portion with the circumferential surface of the KO-ru tJ17 with adhesive or bolts. A gas such as compressed air or a liquid such as oil is supplied and sealed in the hollow portion 17 through the fluid introduction hole 14. Further, depending on the case, powder such as sand or iron powder may be enclosed in the hollow portion 17a, either mixed with the fluid or alone. Also, the pressure member '+31 is fu! I summ.

It is preferable to use a pressure-resistant elastic material such as silicone-7 rubber, a polymeric material, or a thin metal plate.

This embodiment is constructed as described above, and the upper O-ru 1
The lower roll 2 and the pressure roll 6h84 are pressed against each other and rotated to manufacture the single-sided corrugated sheet 10, and the corrugated stacks of the lower roll 2 are wound on the surface of the pressure roll 6. The pressurizing member 13a is pressed at a high cycle through the Y8 paper 8' and the hollow paper 9 (the structure is the same mechanism as the conventional Sisigle facer).

However, between the lower roll 2 and the pressure member 13m, which is the main source of vibration, the pressure member 13aj/14fl
has an elastic effect and a vibration damping effect occurs.

That is, (the amount of excitation displacement δ between the lower roll and the pressure roller
) Roll vibration is a response to excitation force, so by reducing the root excitation force, vibrations during steady state and resonance are significantly reduced.
<II sound due to vibration is also significantly reduced.

Next, a second embodiment of the present invention shown in FIG. 4 will be described.

This example differs greatly from the first example in that the pressure member 151) is divided in the i-axis direction.

The same fluid or granular material as described above is preliminarily sealed in the hollow portion 17b, and after being wound, it is stopped by a fixing member 18. The fixing method and materials are the same as in the previous embodiment. Furthermore, it is convenient for assembly if the pressure member is wound in a spiral shape.

The functions and effects of this embodiment are similar to those of the first embodiment.

In this way, according to the pressure of the present invention, the annular pressure member fitted around the outer periphery of the pressure roll acts as a buffer for the vibrations generated between the lower roll and pressures 0 to 9, so the vibrations are reduced, and based on this, the liner Paper damage phenomena such as cracks are eliminated, and noise is also reduced.
