Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gluing machine for applying glue to the back surface of wallpaper.

[0002]

2. Description of the Related Art An automatic wallpaper sizing machine that applies sizing to the back surface of a conventionally known wallpaper (cloth) with a sizing roller, and a sizing roller for transferring the sizing in a sizing box to the sizing roller. There are one with one installed in the glue box and one with two installed. Initially, only one glue-up roller was installed, but recently, two glue-up rollers were installed in order to reduce the size and weight. The reason is that in order to achieve compactness and weight reduction, the rollers were made thinner and the depth of the machine was made smaller. Therefore, the depth of the glue box had to be made smaller, but the glue box must be deeper in order to secure the same amount of glue as before. In order to effectively pull up the glue in the deep glue box with one glue roller, it is necessary to increase the diameter of the roller. By increasing it, the volume of the roller also increases and the effective glue volume in the glue box increases too much. Absent. Therefore, in order to reduce the occupied volume of the roller and increase the effective glue capacity in the glue box, two glue upper rollers having a small roller diameter have been installed in the glue box. It is well known that the present applicant has carried out the installation of the two glue-on rollers.

In the conventional automatic wallpaper gluing machine, the roller on the glue is 1
FIG. 9 shows a schematic configuration of the one installed, and FIG. 5 shows a schematic configuration of the two installed. Hereinafter, an automatic wallpaper gluing machine having two glue upper rollers will be described. The automatic wallpaper sizing machine is provided with a measuring roller 5, a sending roller 12, a high tension roller 4, a doctor roller 11, a sizing roller 8, a pressing roller 6 and a peeling roller 7 from the side where the wallpaper is inserted. And
In the glue box B which can be detached from the glue machine, a glue upper roller 9 on the side away from the glue roller 8 and a glue upper roller 10 on the side close to the glue roller 8 are detachably provided for cleaning or the like. (See FIG. 8). The wallpaper A to be glued is sandwiched by two rubber rollers, a measuring roller 5 and a feeding roller 12, and fed into the glue machine body.

The measuring roller 5 is supported by bearing members at both ends and can freely rotate. Further, this roller is pressed against the feeding roller 12 side by a spring, and follows the feeding of the wallpaper A and rotates in one direction.

By keeping the outer diameter of the measuring roller 5 at a constant value, the amount of rotation of the roller is measured by means such as detecting with a sensor a slit plate whose circumference is equally divided,
The distance traveled by one point on the outer circumference of the roller on the circumference, that is, the length of the fed (glued) wallpaper A can be measured. This information is always displayed on the gluing machine operation unit, and the worker can work while watching the situation. When the length set in advance is reached, the gluing machine automatically stops.

After stopping the gluing machine, an operator runs a blade of a cutter knife along a cutter guide (not shown),
Wallpaper A is cut and glued to the desired length.
To get

By adjusting the gap between the doctor roller 11 and the gluing roller 8, the thickness of the glue adhering to the outer periphery of the gluing roller 8 is adjusted, that is, the amount of gluing to the wallpaper A is adjusted. The thickness of the glue layer comes into contact with the back surface of the wallpaper A to transfer the glue to the back surface of the wallpaper A.

The glued wallpaper A is smoothed with the glue transferred by the peeling roller 7, discharged from the front of the main body, folded with the glue surfaces aligned, and stored in a folded state until pasting. The high tension roller 4 and the pressing roller 6 have a function of making the wrapping angle of the cloth around the gluing roller 8 constant, making the gluing uniform, and carrying the wallpaper A smoothly.

The glue 3 is stored in a glue box B, which is detachably attached in the front-rear direction to the lower part of the main body of the gluing machine, and which is supported near the four corners of the bottom surface. As shown in FIG. 6, the cross-sectional shape of the glue box B is such that the bottom surface of the glue box B is inclined from the front and rear of the box and is deepest near the position of the glue upper roller 9. An adhesive upper roller 10 and an adhesive upper roller 9 are attached to the adhesive roller 8 for transferring the adhesive 3 to the wallpaper A in order to efficiently transfer the adhesive 3 in the adhesive box. The gluing roller 8 and the gluing roller 10 are rotated by gears 13 and 13a (see FIG. 7) provided at their ends to rotate in opposite directions, and the gluing roller 10 and the gluing roller 9 respectively Rotation is transmitted by gears 13b and 13c (see FIG. 7) provided at the ends of the gears so that they rotate in opposite directions.

[0010]

In the conventional gluing machine, as shown in FIGS. 5, 6 and 7, the gluing box is held on the stationary portion on the wallpaper discharge side, It is held by the glue box receiver 1 on one side. This glue box receiver 1
It is fixed to the gluing machine with a screw 2. At this time, the glue box holder 1 is provided with a long hole 1a for position adjustment, and the long hole 1a is fixed with the screw 2. . The glue upper roller 10 and the glue upper roller 9 have a clearance a between the upper and lower glue upper rollers on the bearing portions 14a and 14b provided in the glue box B.
The glue box B
That is, the clearance b between the glue upper roller 10 and the glue-applying roller 8 is adjusted by vertically moving the position of, ie, the position of the glue box receiver 1.

The gluing machine is usually carried to an interior construction site for construction, and is loaded into a car and moved to the site. In addition, the glue box may be taken in and out, removed, cleaned and assembled during use. Then, although the glue box B is deformed or the position of the glue box receiver 1 is changed even though the glue box B is fixed by the screw 2, the glue roller 8 and the glue upper roller 1 are changed.
It may happen that the gap b between 0 has to be readjusted.

A clearance gauge is usually used to adjust the clearance b between the gluing roller 8 and the gluing roller 10, but when there is no gluing roller, first, when there is no gluing, for example, several business cards. Prepare an article that is close to you and has a thickness approximately the same as the specified clearance b, loosen the screw 2 and lower the glue box B, pull out the glue box B, and glue the name card with the glue roller 8 and glue. The glue box B is returned so that it is properly sandwiched between the upper roller 10 and the glue box tray 1 and is held so as to be lifted up. In this way, the screw 2 is tightened and fixed again after having the predetermined clearance b. This is also performed on the other glue box receiver 1 side to complete the adjustment.

However, this work is troublesome as described above, and the work becomes even more difficult when the adhesive is contained.

As shown in FIG. 6, when the amount of the glue 3 is reduced, the glue upper roller 9 on the lower side to the glue upper roller 1 on the upper side.
0, and the upper glue roller 10 to the glue roller 8
The glue is transferred to the glue roller, but the amount of glue (thickness of the glue) transferred to the glue upper roller 10 is about ½ of the gap a between the glue upper roller 9 and the glue upper roller 10. In addition, the amount of glue (thickness of glue) transferred from the glue-up roller 10 to the glue-up roller 8 is about 1/2 of the gap b between the glue-up roller 10 and the glue-up roller 8. Therefore, the gap b between the glue upper roller 10 and the glue roller 8 is a gap a.
If it is not more than 1/2 of that, the glue is not transferred to the gluing roller 8.

The amount of glue (thickness of glue) pulled up by the glue upper roller depends on the viscosity of the glue 3 used, and the lower the viscosity, the smaller the amount of glue pulled up. So which glue 3
However, it is necessary to make the gap suitable for the low-viscosity glue 3 so that it is surely transferred. In addition, the gap b between the gluing roller 10 and the gluing roller 8 adjusts the thickness of the glue attached to the outer periphery of the gluing roller 8 in order to adjust the amount of gluing to the wallpaper A described above. 2 of the gap between the doctor roller 11 and the sizing roller 8 (about 0.1 to 0.3 mm)
Should be more than double. Therefore, under the present circumstances, in order to transfer the necessary amount of glue well, the glue upper roller 10
The gap b between the gluing roller 8 and the gluing roller 8 needs to be in the range of about 0.6 to 2 mm when there is one gluing roller. Further, when there are two glue upper rollers, the gap a is about 2 mm at maximum when the viscosity of the glue described above is taken into consideration, and the gap b must be adjusted to half or less of the gap a. Therefore, when two glue upper rollers are installed, the clearance b between the glue applying roller 8 and the glue upper roller 10 has a stricter adjustment range than when there is one glue upper roller (range of 1 mm or more), That is, there are only a few mm of commas. For this reason, there was a problem that the glue did not reach the gluing roller due to a slight shift, a wear of the bearing, or a warp or a shift caused by dropping the machine itself. .

As described above, the gap between the gluing roller 8 and the gluing roller 10 is important in order to transfer the glue well, and if a gap occurs, adjustment is necessary. Then, the adjustment work is a very troublesome work as described above. Even if the adjustment is performed once, it may change due to transportation, disassembly, cleaning, and assembly, and the gap may be misaligned, and the adjustment has to be performed each time.
Therefore, the gluing roller 8 can be used without any troublesome adjustment.
The gap between the glue roller 10 and the glue roller 10 can be secured in a predetermined gap,
It is desired that the gluing work can be done smoothly. Further, it is also necessary to develop a mechanism that allows the glue to be sufficiently transferred to the gluing roller 8 or the glue upper roller 10 side even if the adjustment of the roller interval is made rough to some extent.

As shown in FIG. 8, the glue upper rollers 9 and 10 have bearing shafts 14a and 14b mounted on the glue box B, in which a shaft on one side of the roller is inserted into a shaft hole, and the shaft on one side is a shaft hole portion. It is fitted into the shaft hole by utilizing the elasticity of the notch groove and the bearing member provided in the shaft hole. The notch groove has a structure that allows the shaft to pass through when the roller is attached or detached, and closes so that the shaft does not come off after fitting. The arrow F shown in FIG. 8A indicates the direction in which the glue upper roller 10 and the glue upper roller 9 are removed from the shaft hole with the cutout groove, and the arrow E shows the cutout groove on one side. The shaft is removed from the shaft hole, the other shaft is pulled out from the shaft hole with the shaft tilted, and the mounting is performed by performing the reverse operation. Further, as shown in FIGS. 8B and 8C, the shaft hole provided with the notch groove and the shaft hole are arranged in the bearing portions 14a and 14b, respectively.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described with reference to the drawings. As a first embodiment, FIG. 1 shows a front view, FIG. 2 shows a side view, and FIG. 3 shows details of a bearing portion of a glue roller. 1 to 3, parts related to the essential part of the invention are shown, and parts similar to those of the related art are not shown and described.

As one of the embodiments of the present invention, in order to transfer a larger amount of glue to the glue upper roller 10 that transfers the glue to the glue roller 8 even if the glue 3 in the glue box B becomes small. A transfer roller (any diameter having a diameter capable of blocking and accumulating the glue) may be disposed between the glue upper rollers 9 and 10 as the glue receiving member 16 over the entire width in the width direction or substantially the entire width of the roller. This glue receiving member 16
Over the entire width or almost the entire width of the glue upper roller 9, the glue that is not transferred to the glue upper roller 10 and returns to the glue box is blocked, and the glue pool X is generated. That is, the thickness of the glue that is not transferred to the glue upper roller 10 and returns to the glue box B is about 1/2 of the gap a (1 due to the influence of gravity or the like).
/ More than 2), and this glue is dammed so as not to return to the glue box B. Glue roller 9 and glue receiving member 1
In the case of No. 6, if the clearance is made small to the extent that it does not come into contact, the amount of glue that returns to the glue box is small, and the glue that accumulates in the glue reservoir X part can be increased.

As shown in FIG. 1, the transfer roller 16 is installed in such a state that the skimmer a is blocked. The gear 13 of the gluing roller 8 is the gear 13a of the gluing roller 10
The gear 13a meshes with the gear 13c of the glue upper roller 9
In mesh with each other, each of them rotates at a predetermined peripheral speed ratio by the rotation of the motor. Unlike the conventional structure, the gear meshing is arranged on one side because the force applied to the bearing portion when the motor is driven is concentrated on the bearing portion of the glue upper roller 10 9, 1
This is because the force is received by both of them, and the concentration of the bearing portion 14b on a specific portion is eliminated, and the wear of the bearing is reduced.

As shown in FIG. 2, the transfer roller 16 allows the glue to be sufficiently accumulated between the glue upper rollers 9 and 10. Therefore, it is not necessary to pay special attention to the gap between the gaps a as in the conventional case, and the gap can be set larger than that in the conventional gap a. Then, since sufficient glue is transferred to the glue upper roller 10 and the glue rises toward the glue roller 8, it is necessary to pay attention only to the gap b between the rollers.
That is, the state is the same as the state of one conventional glue upper roller.

Since it is the same as one glue roller, the gap between the gaps b may be a little wider, and a slight deviation or the like does not affect the gluing work.

The transfer roller 16 is not limited to a metal transfer roller, and may be a resin transfer roller as long as it can sufficiently block the adhesive even if it is bent by the resistance of the adhesive. In the case of a metal transfer roller, if a thin tape or the like is wound so that it may come into contact with the glue upper roller 9, it is possible to prevent damage to the rollers and to prevent noise generated by contact between the rollers. it can.

FIG. 3 shows a perspective view of this glue box and a bearing portion for explanation. FIG. 3A shows a perspective view of the glue box B. Bearing portions 14a and 14b are attached to both sides of the glue box B, and glue upper rollers 9 and 10 and a transfer roller 16 are set. FIGS. 3B and 3C are views of the bearing portions 14a and 14b as viewed from the inside of the glue box B. The transfer roller 16 is held by bearings 14c and 14d. The glue upper rollers 9 and 10 and the transfer roller 16 are all bearing portions 14.
Since the bearings a and 14b are used, the gap between the rollers can be determined by the shape of the bearing. Therefore, the distance between the glue upper roller 9 and the glue upper roller 10 and the distance between the glue upper roller 9 and the transfer roller 16 can be determined by the design of the bearing portion, and a desired distance can be realized.

In the above embodiment, an example in which the transfer roller 16 is installed between the glue upper roller 9 and the glue upper roller 10 has been described, but the transfer roller 16 is also provided between the glue applying roller 8 and the glue upper roller 10. 16 may be installed in the same configuration as described above, so that even if the gap between the gaps b is considerably wide, a large amount of the glue 3 can be reliably transferred to the gluing roller 8.

The second embodiment will be described with reference to FIG.
The use of the transfer roller is the same as in the first embodiment. In the first embodiment, the bearing portions 14a and 14b
Was attached to the side wall of the glue box B, but in the second embodiment, the bearing portions 14a and 14b are configured to be slidable in the vertical direction without being attached to the side wall of the glue box B.
Here, in FIG. 4, only the bearing portion 14a is shown, but the bearing portion 14b is omitted because it has a symmetrical shape.

A guide member 17 for allowing the bearing portions 14a and 14b to slide vertically is attached to the side wall of the glue box B as shown in FIG. 4, and a gap is formed between the side wall of the glue box and the guide member. The bearing member is fitted to the shaft so that it can slide up and down.

A ring 15 for contacting the sizing roller 8 for determining the clearance b is installed on the sizing roller 10. The ring 15 is installed near both ends of the glue upper roller 10 so as to have a position that does not affect the transfer of the glue, and a width that does not affect the transfer.

At the bottom of the bearing portion 14a, there is provided a flexible portion 14e for applying a biasing force for the ring 15 to come into contact with the gluing roller 8 when the glue box B is installed. In order to bend the flexible portion 14e to raise the entire bearing portion upward in the vertical direction, the thickness of the ring 15 serves as a gap b to form a fixed gap with the gluing roller 8 and the glue upper roller 10.
It can be configured in between.

Since it is the second embodiment as described above, the members such as the bearing portion and the roller in the glue box can be disassembled simply by pulling out the bearing portion in the upward direction, and it is easy to wash at the time of washing. Further, by simply installing a glue box on the gluing machine, it is possible to configure a constant gap b without requiring any special adjustment, and it is possible to configure a gluing machine that is easy to use.

[0033]

As described above, in the wallpaper sizing machine in which two or more paste-up rollers according to the present invention are installed in the paste box, it is related to the number of steps of transferring the paste using the paste-up rollers. Instead, more glue can be transferred to the glue upper roller to which the glue is transferred, and the width of the gap between the glue applying roller and the glue upper roller transferring the glue to the glue applying roller can be increased. This makes it easier to adjust the above-mentioned gap during gluing work, widens the tolerance range for changes in the gap between rollers due to wear of bearings, etc., and ensures that glue is applied to the back surface of wallpaper. You can do it.

Further, by making the bearing portion of the glue roller a single structure, it is possible to easily attach and detach.

From the above, it is possible to omit the adjustment work, which has been a very troublesome work up to now, and surely apply the glue to the back surface of the wallpaper to perform the smooth gluing work.
