2. Description of the Related Art FIG. 2 is an explanatory view showing a schematic configuration of a conventional general wallpaper gluing machine. As shown in FIG. 2, the conventional wallpaper sizing machine includes an upper structure 2 and a lower structure 3 which form a sizing machine body 1, and a leg portion 4 which supports the sizing machine body 1 at a predetermined height. A stand (cross roll) 5 for suspending a wall covering material (cross) 7 wound in a roll shape on the rear surface side of the gluing machine main body 1, a glue tub 6 provided in the lower structure, and the upper portion. It is mainly composed of a plurality of rolls 9 to 15 arranged in the structure 2 and the lower structure 3 via gears, and a control box 17 for controlling driving of the plurality of rolls 9 to 15. A hinge 21 that connects the upper body 2 and the lower body 3 to each other is provided on the front surface side of the gluing machine body 1, and the hinge body 21 is connected to the upper body 2 on the rear surface side of the gluing machine body 1. A hook (not shown) for fixing the lower structure 3 to each other is provided.

Assembling the plurality of rolls, in the upper structure 2, applies a feeding tension to the upper pinch roll 13a and the cross 7 which constitute a take-in pinch roll for taking the cross 7 into the main body 1. Drive rolls 12 are arranged in parallel with each other, and these are supported in holes formed in the side plate of the upper structure 2 directly or via a solid lubricating ring. Further, a cloth 7 is provided between the upper pinch roll 13a and the drive roll 12.
The pressing rolls 14 that press and rotate from above are arranged in parallel.

Further, in the lower structure 3, a lower pinch roll 13b which constitutes a pinch roll for taking in the cloth 7 into the main body 1, a gluing roll 9,
A leveling roll 11 is arranged in parallel, and a doctor roll 10 and a sizing roll 15 are arranged in contact with the sizing roll 9. The gluing roll 9 is the lower structure 3
Is supported by a ball bearing press-fitted into the side plate of
The lower pinch roll 13b, the doctor roll 10 and the leveling roll 11 are respectively supported by holes bored in the side plate of the lower structure 3 either directly or through a solid lubricating ring, and the glue-up roll 15 is inside the glue trough 6. The bearing is directly supported by a bearing plate (not shown) made of engineering plastic placed on the side surface.

Further, the control box 17 is
The control box is detachably attached to one end side of the plurality of rolls 9 to 15, and accommodates therein a motor that rotationally drives the plurality of rolls 9 to 15 and a control device that controls the drive of the motor. From the operation panel 17a provided on the side surface of the control unit 17, control information including an operation command and an operation condition can be given to the control device.

An encoder (not shown) for measuring the number of revolutions of the plurality of rolls 9 to 15 which are rotationally driven by the motor is housed in the side cover 2a of the upper structure 2, and the encoder is provided. The rotation speeds of the plurality of rolls measured by are output to the control box 17 via the plug 20.

When performing the gluing work using the wallpaper gluing machine configured as described above, the operator first operates the dials 22 attached to the front faces of both ends of the main body 1 to make a doctor roll. The position of the doctor roll 10 is changed so as to change the relative gap (gap) between the adhesive roll 10 and the gluing roll 9, and the gluing roll 9 is adjusted so that a desired amount of glue (glue thickness) adheres to the cloth 7.

After that, the positioning of the cloth 7 at the reference position and the trial operation of the gluing roll 9 for eliminating the glue unevenness of the gluing are performed, and in order to perform the initial setting, the gluing machine main body 1 is opened and the cloth roll 5 is crossed. 7 is pulled out, hung from the rear side of the main body through the space between the upper and lower pinch rolls 13a and 13b to the front side, and after closing the gluing machine main body 1, drives the motor built in the control box 17 by an initial set amount. Let

As a result, the rolls connected by the gears rotate at a predetermined peripheral speed ratio, whereby the glue in the trough adhered to the sizing roll 9 by the sizing roll 15 is removed by the doctor roll 10.
The adhesive on the surface of the gluing roll 9 is applied to the back surface of the cloth 7 which is adjusted by the pressing roll 14 and moves with the rotation of the gluing roll 9 under the effect of the pressing roll 14.

The glued cloth 7 is then pulled out by the drive roll 12 and the leveling roll 11 in a state where a proper tension is applied and comes out to the front surface of the main body. At this time, the peripheral speed of the leveling roll 11 is increased. The leveling action of the glue surface is given by the difference. When the cloth 7 comes out to the front by the initial set amount, the motor is once stopped, the unnecessary cloth at the tip is cut by the cutter along the cutter guide 16, and the initial setting is completed.

Next, the operator operates the control box 17
When a desired cross length is input from the operation panel 17a of No. 3 and the motor is driven in the same manner, the cloth 7 of a desired length glued to the back surface of the entire length is ejected from the front surface of the main body, and along the cutter guide 16 It is cut at −, folded by an operator, and deposited on the front tray 8.

After the cloth 7 having a desired length is accumulated on the tray 8 on the front surface, the motor is once again stopped, and the desired cloth length is input again from the operation panel 17a of the control box 17 to drive the motor. , This work is repeated.

[0013]

However, in the above-mentioned conventional wallpaper gluing machine, in order to adjust the amount of glue (glue thickness) applied to the cloth 7, the dials 22 attached to the front faces of both ends of the main body 1 are used. The amount of glue applied to the cloth 7, that is, the amount of glue adhered to the gluing roll 9 is adjusted by changing the relative gap (gap) between the gluing roll 9 and the doctor roll 10 in this case. There is a problem that the desired amount of glue cannot be adjusted even if the dial 22 is operated.

That is, in the conventional wallpaper gluing machine, even if the dial 22 is operated in order to change the relative gap (gap) between the doctor roll 10 and the gluing roll 9, the doctor roll 10 and the doctor roll 10 are separated by a predetermined distance. Since the relative distance between the gluing rolls 9 cannot be changed, there is a problem in that the amount of glue desired by the operator cannot be finely adjusted.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a wallpaper gluing machine capable of finely adjusting the amount of glue (glue thickness) applied to the wall covering material.

[0016]

In order to achieve the above object, a wallpaper sizing machine according to a first aspect of the present invention comprises a doctor roll and a sizing roll which are rotationally driven via gears in the main body. The sheet-shaped wall covering material drawn from the front part of the main body is moved along a predetermined path by a plurality of rolls including the rolls, and the glue in the glue tub arranged below the main body is moved to the gluing roll. While adjusting the amount of glue adhered to the gluing roll by a relative position adjusting mechanism that changes the relative position of the doctor roll and the doctor roll, the adjusted glue is continuously applied from the gluing roll to the back surface of the wall covering material. In the wallpaper gluing machine for applying, the doctor roll is rotated at a peripheral speed higher than the peripheral speed of the gluing roll.

[0017]

The wallpaper sizing machine according to the first aspect of the present invention is configured as described above, and the peripheral speed of the doctor roll is set higher than the peripheral speed of the sizing roll. That is, since the doctor roll and the gluing roll are rotated in opposite directions,
When the peripheral speed of the doctor roll is made higher than the peripheral speed of the gluing roll, the glue adhered to the surface of the gluing roll is wound around the doctor roll, and the amount of glue adhering to the surface of the gluing roll decreases. Therefore, it becomes possible to finely adjust the amount of glue (glue thickness) applied to the wall covering material.

[0018]

1 is a schematic side view showing the inside of a main body 1 of a wallpaper sizing machine according to an embodiment of the present invention. The difference between the wallpaper sizing machine according to the present embodiment and the wallpaper sizing machine shown in the conventional example is that the peripheral speed of the doctor roll 10 is rotated at a higher peripheral speed than the peripheral speed of the sizing roll 9. There is no difference in appearance from the wallpaper sizing machine shown in the conventional example. The same parts as those in the conventional example are designated by the same reference numerals and the description thereof will be omitted.

Here, the difference from the conventional example when the peripheral speed of the doctor roll 10 is rotated at a higher peripheral speed than the peripheral speed of the gluing roll 9 will be described. First, in the present invention, when the peripheral speed of the gluing roll is 1,
If the peripheral speed of the doctor roll is set to 1.10, the relative distance between the gluing roll 9 and the doctor roll 10 is set to the dial 22.
When (see FIG. 2) is manipulated and changed by a predetermined amount, the amount of glue attached to the back surface of the cloth 7 increases by about 30 g / m ² .

On the other hand, in the conventional device, when the peripheral speed of the gluing roll was 1, the peripheral speed of the doctor roll was 0.75, so the relative distance between the gluing roll 9 and the doctor roll 10 was When the dial 22 (see FIG. 2) is operated and changed by a predetermined amount, the amount of glue attached to the back surface of the cloth 7 increases by 50 g / m ² .

As a result, by increasing the peripheral speed of the doctor roll 10 relative to the gluing roll 9, the cloth 7
The amount of glue applied to the can be finely adjusted.

Specifically, this can be easily performed by changing the number of teeth of the gear attached to the shaft end of the doctor roll.

Further, in the present embodiment, the case where the present invention is applied to the wallpaper sizing machine with a motor has been described, but the cloth 7 is pulled into the sizing machine main body 1 by the operator's manual work, It goes without saying that the present invention can also be applied to a so-called manual type wallpaper gluing machine that applies glue to the back surface of the.

[0024]

As described above, according to the present invention, the peripheral speed of the doctor roll is set to be higher than the peripheral speed of the gluing roll, so that the amount of glue (glue thickness) applied to the wall covering material can be finely adjusted. There is.
