Description

TECHNICAL FIELD The present invention relates to a wallpaper gluing machine for producing a sheet-shaped wall covering material in which a lining is applied with a gluing agent, which is used, for example, when applying wallpaper to a house. .

[Prior Art] FIG. 1 is a perspective view showing a configuration of a manual wallpaper sizing machine, and FIG. 2 is a perspective view showing a configuration of an automatic wallpaper sizing machine. As shown in the figure, the main parts of the wallpaper gluing machine 1 are arranged in the glue tub 3 supported by the legs 2, the cross roll 4 arranged in the rear part of the glue tub 3, and the front part of the glue tub 3. It is composed of a cross receiver 5.

The cloth 7 is wound on the cloth roll 4, and the pail 3
The upper lid portion 6 is put over the cloth so as to sandwich the cloth 7.
For this reason, the upper lid portion 6 is hinge-joined at the rear portion of the glue pail 3, and the cloth 7 is passed through during this period. The upper lid 6 has a counter mounting stay 61 for measuring the length of the pulled out cloth 7.
And two drive rolls 6 that press the cloth 7 from above
2,63 and are attached. The glue tub 3 has a sizing roll 31 for transferring and applying the sizing attached to itself to the back surface of the cloth 7, and a doctor roll for adjusting the thickness of the sizing attached to the sizing roll 31.
32 and a leveling roll 33 for uniformly leveling the glue applied to the back surface of the cloth 7 are attached.

The counter mounting stay 61, the drive roll 63, the sizing roll 31, and the leveling roll 33 are interlocked with each other by gears.

Further, a cutter guide 34, which is a groove for guiding a cutter for cutting the cloth 7, is provided on the entire surface of the glue tub 3.

In actual operation, the back surface of the cloth 7 is brought into contact with the sizing roll 31 and the leveling roll 33, and the front surface of the cloth 7 is driven by the drive roll 6
Contact 2,63. Hold both sides of Cross 7 by hand and pull it out forward. By the drawer at this time, the drive roll 63, the sizing roll 31, and the leveling roll 33 which are interlocked with each other are rotated,
A uniform glue can be transferred and applied to the cloth 7. The cloth 7 to which the glue has been applied is alternately folded and held on the cloth receiver 5 with the back surface facing outward. When the glued cloth 7 has a predetermined length, the cutter is moved along the groove of the cutter guide 34 on the entire surface of the glue pail to cut the cloth 7.

Further, a drive roll 63 and a sizing roll 31 which are interlocked with each other by gears of the wallpaper sizing machine shown in FIG.
Also, in the automatic wallpaper gluing machine in which the leveling roll 33 was driven by the motor 8, the glued cloth that was discharged in the same manner was folded by hand.

In the conventional wallpaper sizing machine, the peripheral speed ratio of the sizing roll to the drive roll and the leveling roll is set to 1: 1.01. The ideal peripheral speed ratio of the gluing roll to the drive roll and leveling roll is considered to be 1: 1.However, in practice, the circumference of the drive roll and leveling roll should be taken into consideration in consideration of the expansion and contraction of the cut tape that cuts the cloth in layers. The speed ratio was faster than that of the sizing roll.

On the other hand, the peripheral speed ratio of the sizing roll to the drive roll and the leveling roll was 1: 0.96.

[Problems to be Solved by the Invention] However, if the peripheral speed ratio of the drive roll and the leveling roll is set to be 1% faster than that of the glued roll as described above, when the cloth is pulled out, both rolls serve as a brake, and vice versa. If it was delayed by 4%, reverse resistance would be applied to the cross, and it would still be a brake, and a large force was required to pull out the cross.

It is an object of the present invention to obtain a wallpaper sizing machine that makes it easy to pull out a cloth.

[Means for Solving the Problems] In the wallpaper gluing machine according to the present invention, a glue tub, a gluing roll detachably disposed in the gluing tub, and a gluing roll arranged in parallel with the gluing roll. A drive roll and a leveling roll, the gluing roll, the drive roll, and the leveling roll are arranged so as to rotate in conjunction with each other, and the gluing roll is rotated by the rotation of the gluing roll. In a wallpaper gluing machine that transfers and applies the glue in the glue tub attached to the outer peripheral surface from the outer peripheral surface of the gluing roll to the sheet-shaped wall covering, the peripheral speed of the gluing roll and the drive roll at the time of gluing The ratio is 1 or less, and the peripheral speed ratio between the gluing roll and the leveling roll is 1 or more.

[Operation] In the present invention, the peripheral speed ratio of the gluing roll and the drive roll at the time of gluing glue is set to 1 or less, and the peripheral speed ratio of the gluing roll to the leveling roll is set to 1 or more. .

That is, the peripheral speed ratio of the gluing roll to the drive roll and the leveling roll is ideally 1: 1 in terms of cross drawing,
When the glue is attached to the cloth, the glue is attached to the gluing roll and the leveling roll to increase the roll diameter, and the glue is not attached to the drive roll. In addition, during use, the sizing roll and the leveling roll have large slippage with the cloth, and the friction with the drive roll does not change.

At this time, between the gluing roll and the leveling roll, the one that the leveling roll rotates faster than the gluing roll (the peripheral speed ratio of the averaging roll is larger than that of the gluing roll) is The leveling effect is great, and with the sizing roll and the drive roll,
When the drive roll rotates slower than the gluing roll (the peripheral speed ratio of the drive roll is smaller than that of the gluing roll), the gluing roll can be satisfactorily transferred and applied to the cloth. A uniform transfer coating surface can be obtained, and the cloth can be pulled out lightly.

Example The doctor roll adjusts the thickness of the adhesive attached to the adhesive roll. Maximum glue thickness of this doctor roll (0.25mm)
From the minimum adhesive thickness (0.95 mm), the gluing work was performed. In addition, the changes in the peripheral speed ratios of the sizing roll and the drive roll, and the sizing roll and the leveling roll, were compared between the maximum paste thickness (0.25 mm) and the maximum paste thickness (0.95 mm).

The results are shown in Table 1 below.

The peripheral speed ratio is as shown in Table 1, and with the wallpaper sizing machine according to the present invention, the cloth can be pulled out easily from the maximum paste thickness to the minimum paste thickness, and the paste-coated surface has no coating unevenness and is good. became.

That is, the peripheral speed ratio of the gluing roll to the drive roll and the leveling roll is ideally 1: 1 in terms of cross drawing,
When the glue is attached to the cloth, the glue is attached to the gluing roll and the leveling roll to increase the roll diameter, and the glue is not attached to the drive roll. In addition, during use, the sizing roll and the leveling roll have large slippage with the cloth, and the friction with the drive roll does not change.

At this time, in the gluing roll and the leveling roll, the one in which the peripheral speed ratio of the averaging roll is larger than the gluing roll has a larger leveling effect of the averaging roll, and in the gluing roll and the drive roll, When the peripheral speed ratio of the drive roll is smaller than that of the gluing roll, the gluing roll can transfer the paste to the cloth better, and a uniform transfer coating surface can be obtained and the cloth can be pulled out easily. I knew I could do it.

[Advantages of the Invention] As described above, the present invention sets the peripheral speed ratio between the gluing roll and the drive roll at the time of gluing glue to 1 or less, and sets the peripheral speed ratio between the gluing roll and the leveling roll to 1 or more. It is what That is, the peripheral speed ratio of the gluing roll to the drive roll and the leveling roll is ideally 1: 1 from the aspect of the cross drawing, but when the glue is attached to the cloth, the gluing roll and the leveling roll are The glue adheres to the drive roll and the roll diameter increases, and the glue does not adhere to the drive roll. In addition, during use, the sizing roll and the leveling roll have large slippage with the cloth, and the friction with the drive roll does not change.

At this time, in the gluing roll and the leveling roll, the one in which the peripheral speed ratio of the averaging roll is larger than the gluing roll has a larger leveling effect of the averaging roll, and in the gluing roll and the drive roll, If the peripheral speed ratio of the drive roll is smaller than that of the gluing roll, the gluing roll can transfer the paste to the cloth better, and a uniform transfer coating surface can be obtained and the cloth can be pulled out lightly. It has the effect of
