[0001]
[Industrial application fields]
The present invention relates to a gluing machine that applies glue to the back surface of wallpaper.
[0002]
[Prior art]
This is an automatic wallpaper gluing machine that applies glue to the back of wallpaper (cloth), which has been known in the past, with a gluing roller. There are one installed one and two installed. At first, only one roller for glue was installed, but recently, two rollers for glue were installed corresponding to compactness and weight reduction. This is because in order to achieve compactness and weight reduction, the depth of the machine was reduced by thinning the rollers. Therefore, the depth of the glue box has to be reduced, but the glue box has to be deepened in order to secure the paste capacity to the same level as in the past. In order to effectively pull up the glue in the deep glue box with a single glue roller, it is necessary to increase the diameter of the roller. By increasing the size, the volume of the roller increases and the effective glue capacity 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 are installed in the glue box. The installation of the two glue upper rollers is well known by the applicant.
[0003]
FIG. 9 shows a schematic configuration of a conventional automatic wallpaper pasting machine in which one gluing roller is installed, and FIG. 5 shows a schematic configuration of two gluing rollers installed. Hereinafter, an automatic wallpaper pasting machine in which two glue upper rollers are installed will be described. In the automatic wallpaper pasting machine, a measuring roller 5, a feeding roller 12, a high tension roller 4, a doctor roller 11, a pasting roller 8, a presser roller 6, and a dry roller 7 are arranged from the side of inserting the wallpaper. In the glue box B that can be detached from the gluing machine, a gluing roller 9 on the side away from the gluing roller 8 and a gluing roller 10 on the side close to the gluing roller 8 are detachable for cleaning and the like. (See FIG. 8). The wallpaper A to be glued is sandwiched between two rubber rollers of the measuring roller 5 and the feeding roller 12 and fed into the gluing machine main body.
[0004]
The measuring roller 5 is supported by bearing members at both ends, and can rotate freely. This roller is pressed against the feed roller 12 by a spring and rotates in one direction following the feed of the wallpaper A.
[0005]
By setting the outer diameter of the measuring roller 5 to a constant value, the rotation amount of the roller is measured by means such as detecting a slit plate that is equally divided in the circumference with a sensor, and one point on the outer circumference of the roller. The distance traveled on the circumference, that is, the length of the wallpaper A fed (glued) can be measured. This information is always displayed on the pasting machine operation unit, and the operator can work while watching the situation. When the preset length is reached, the gluing machine stops automatically.
[0006]
After stopping the gluing machine, the operator runs the blade of the cutter-knife along a cutter guide (not shown) to cut the wallpaper A to obtain the wallpaper A glued to the desired predetermined length.
[0007]
By adjusting the gap between the doctor roller 11 and the glue roller 8, the thickness of the glue adhering to the outer periphery of the glue roller 8 is adjusted, that is, the amount of glue on the wallpaper A is adjusted. The glue layer whose thickness is adjusted comes into contact with the back surface of the wallpaper A, and the paste is transferred to the back surface of the wallpaper A.
[0008]
The glued wallpaper A is leveled by the glue roller 7, is discharged from the front surface of the main body, is folded in a state where the glue surfaces are combined, and is stored in a folded state until the application. The high tension roller 4 and the presser roller 6 function to keep the cross wrapping angle around the gluing roller 8 constant, make the gluing uniform, and smoothly transport the wallpaper A.
[0009]
The glue 3 is stored in a glue box B supported at the lower part of the gluing machine main body so as to be detachable in the front-rear direction and in the vicinity of almost four corners of the bottom surface. The cross-sectional shape of the glue box B is as shown in FIG. 6, and 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. In order to efficiently transfer the glue 3 in the glue box to the glued roller 8 for transferring the glue 3 to the wallpaper A, the glue upper roller 10 and the glue upper roller 9 are attached. The glued roller 8 and the glued roller 10 are rotated by the gears 13 and 13a (see FIG. 7) provided at the respective ends and rotated in opposite directions, and the glued roller 10 and the glued roller 9 are respectively Rotation is transmitted by gears 13b and 13c (see FIG. 7) provided at the end of the shaft, and they are configured to rotate in opposite directions.
[0010]
[Problems to be solved by the invention]
In the conventional gluing machine, as shown in FIGS. 5, 6, and 7, the glue box is held by a fixed stage portion on the wallpaper discharge side, and the glue box holder 1 on the other side. Is retained. The glue box receiver 1 is fixed to the gluing machine with screws 2. At this time, the glue box receiver 1 is provided with a long hole 1a for position adjustment, and the screw 2 is inserted into the elongated hole 1a. It is fixed using. The glue upper roller 10 and the glue upper roller 9 are detachably attached to the bearing portions 14a and 14b provided in the glue box B while securing a clearance a between the upper and lower glue upper rollers. The clearance b between the upper glue roller 10 and the glue roller 8 is adjusted by moving the upper and lower sides, that is, the position of the glue box holder 1 up and down.
[0011]
Normally, the gluing machine is usually carried and installed at the interior construction site, and is loaded into a car and moved to the site. Also, the paste box may be put in and taken out, removed, cleaned and assembled during use. Then, although the glue box B is deformed or fixed with the screw 2, the position of the glue box holder 1 is changed, and the gap b between the glue roller 8 and the glue upper roller 10 is re-applied. Sometimes things need to be adjusted.
[0012]
In order to adjust the gap b between the glue roller 8 and the glue upper roller 10, a gap gauge is usually used. However, when there is no glue, there is no glue at first. Then, an article having the same thickness as the predetermined gap b is prepared, the screw 2 is loosened, the glue box B is lowered, the glue box B is pulled out, and the previous business card is pasted with the glue roller 8 and glue upper roller 10. The glue box B is returned so as to be sandwiched between the two and the glue box holder 1 is held so as to be lifted up. In this way, the screw 2 is retightened and fixed after having a predetermined clearance b. This is also done on the other side of the glue box receptacle 1 to complete the adjustment.
[0013]
However, this operation is a labor-intensive operation as described above, and the operation becomes more difficult in a state where glue is contained.
[0014]
As shown in FIG. 6, when the amount of glue 3 is reduced, glue is transferred from the lower glue upper roller 9 to the upper glue upper roller 10 and from the upper glue upper roller 10 to the glue roller 8. The amount of glue (glue thickness) transferred to the upper glue roller 10 is about ½ of the clearance a between the upper glue roller 9 and the upper glue roller 10. The amount of glue (glue thickness) transferred from the upper glue roller 10 to the pasting roller 8 is about ½ of the gap b between the upper glue roller 10 and the pasting roller 8. Therefore, the glue b between the glue upper roller 10 and the glue roller 8 is not less than ½ of the gap a, and the glue is not transferred to the glue roller 8.
[0015]
The amount of glue (glue thickness) that the upper glue roller pulls up differs depending on the viscosity of the glue 3 used, and the lower the viscosity, the smaller the amount of glue that can be pulled up. Therefore, it is necessary to make a clearance suitable for the paste 3 having a low viscosity so that any paste 3 can be reliably transferred. Further, the gap b between the glue upper roller 10 and the glue roller 8 is adjusted by adjusting the thickness of the glue adhered to the outer periphery of the glue roller 8 in order to adjust the amount of glue to the wallpaper A described above. The gap between the doctor roller 11 and the glue roller 8 (about 0.1 to 0.3 mm) must be about twice or more. Therefore, in order to transfer the necessary amount of glue well at present, the gap b between the glue upper roller 10 and the glue roller 8 needs to be in the range of about 0.6 to 2 mm when there is one glue roller. It is. Further, when there are two glue upper rollers, the clearance a is about 2 mm at the maximum based on the viscosity of the adhesive described above, and the clearance b should be adjusted to half or less of the clearance a. Therefore, when two upper glue rollers are installed, the clearance b between the glue roller 8 and the upper glue roller 10 has a stricter adjustment range than when there is one glue roller (range of 1 mm or more), That is, there are only a few mm of commas. Therefore, there was a problem that the glue did not rise up to the glued roller due to slight deviation, wear of the bearing part, or distortion or deviation caused by dropping the machine itself. .
[0016]
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 adjustment is necessary when deviation occurs. And the adjustment work is very troublesome work as described above. Even if it is adjusted once, it may change due to transportation, disassembly cleaning, assembly, etc., and the gap may be distorted, and it has to be adjusted each time. Therefore, it is desired that the gap between the glue roller 8 and the glue upper roller 10 can be secured in a predetermined gap without any troublesome adjustment, and the glueing operation can be performed smoothly. In addition, it is necessary to develop a mechanism that can sufficiently transfer the glue to the gluing roller 8 or the gluing roller 10 side even if the adjustment of the roller interval is roughened to some extent.
[0017]
Further, as shown in FIG. 8, the upper glue rollers 9 and 10 are inserted into the shaft holes in the bearing portions 14a and 14b attached to the glue box B, and the one shaft is provided in the shaft hole portion. It is fitted into the shaft hole using the elasticity of the notch groove and the bearing member. The notch groove has a structure that opens so that the shaft passes when the roller is attached and detached, and closes so that the shaft does not come off after fitting. The arrow F shown in FIG. 8 (a) is the direction when the glue upper roller 10 is removed, and the arrow E is the direction when the glue upper roller 9 is removed from the shaft hole with the notch groove. The shaft is removed from the shaft hole, the other shaft is removed 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, a shaft hole and a shaft hole provided with a notch groove are disposed in the bearing portions 14a and 14b, respectively.
[0018]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present invention provides a wallpaper gluing machine that applies glue on the back surface of a wallpaper by a gluing roller, and has a configuration in which two or more glue rollers are installed in a glue box. The glue in the glue box is transferred to the glue roller in order from the glue roller located at a position far from the glue roller, with respect to the glue glue roller installed at a position adjacent to the glue roller. The glue is configured to be transferred, and the plurality of glue upper rollers are slid in the vertical direction and are supported by a single bearing member having a flexible portion to be raised in the vertical direction, and the interval between the rollers is determined. The gap between the upper glue roller installed on the side close to the glue roller and the ring on which the gap is determined in contact with the glue roller and the glue roller on the side far from the glue roller adjacent to the glue roller Near In, the provision of the transfer roller for dammed glue of returning to the glue box without being transferred to the glue on the roller that is placed on the side closer to the gluing roller to generate a reservoir glue by bearing to the bearing member Thus, the wallpaper pasting machine is characterized in that a large amount of glue can be transferred to the upper glue roller for transferring glue to the pasting roller. A transfer roller is provided, and it is made closer to the side farther from the gluing roller to form a glue reservoir, so that the gluing can be reliably transferred to the upper gluing roller near the gluing roller.
[0019]
According to a second aspect of the present invention, there is provided the wallpaper pasting machine according to the first aspect, wherein the transfer roller is detachably supported by the bearing member on which the glue upper roller is supported. By adopting the above-described configuration, the distance between the transfer roller and the upper glue roller can be reliably set to a predetermined position, and the generation of the glue pool can be ensured.
[0020]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described with reference to the drawings. As a first embodiment, FIG. 1 is a front view, FIG. 2 is a side view, and FIG. 3 shows details of a bearing portion of an adhesive upper roller. 1 to 3 show parts related to the main part of the invention, and illustration and description of parts that are the same as conventional ones are omitted.
[0021]
As one embodiment of the present invention, even when the amount of glue 3 in the glue box B is reduced, the glue upper roller 10 for transferring glue to the glue roller 8 is used to transfer more glue. Between the rollers 9 and 10, a transfer roller (any diameter as long as it can squeeze and accumulate glue) is disposed as the glue receiving member 16 over the entire width in the width direction of the roller or substantially the entire width. The glue receiving member 16 blocks the glue that tries to return to the glue box without being transferred to the glue upper roller 10 over the entire width or substantially the entire width of the glue upper roller 9, thereby generating the glue pool X. That is, the thickness of the glue that returns to the glue box B without being transferred to the glue upper roller 10 is about ½ of the gap a (more than ½ due to the influence of gravity or the like). Stop it so that it doesn't come back. If the clearance is reduced to such an extent that the glue upper roller 9 and the glue receiving member 16 do not come into contact with each other, the amount of glue returning to the glue box is small, and the glue accumulated in the glue reservoir X can be increased.
[0022]
As shown in FIG. 1, the transfer roller 16 is installed so as to block the gap a. The gear 13 of the gluing roller 8 meshes with the gear 13a of the gluing roller 10, the gear 13a meshes with the gear 13c of the gluing roller 9, and each rotates at a predetermined peripheral speed ratio by the rotation of the motor. Unlike the conventional configuration, the meshing of the gears is grouped on one side because the force applied to the bearing portion when the drive from the motor is applied is concentrated on the bearing portion of the glue upper roller 10. This is because the force is received by both 9, 9, and the concentration of the bearing portion 14b at a specific location is eliminated and the wear of the bearing is reduced.
[0023]
As shown in FIG. 2, the transfer roller 16 causes the glue to sufficiently accumulate between the glue upper rollers 9 and 10. Therefore, it is not necessary to pay particular attention to the gap a as in the conventional case, and the gap can be set larger than the conventional gap a. Then, since a sufficient amount of glue is transferred to the glue upper roller 10 and the glue rises toward the glue roller 8, it is only necessary to pay attention to the gap b between the rollers. That is, it becomes the same as the state of one conventional glue upper roller.
[0024]
Since it is the same as one glue roller, the gap of the clearance b may be somewhat wide, and a slight deviation or the like will not affect the gluing operation.
[0025]
The transfer roller 16 is not limited to a metal transfer roller, but may be made of resin, as long as it can sufficiently dampen the paste even if it is bent by the resistance of the paste. When it is configured as a metal transfer roller, winding a thin tape or the like so that it can be in contact with the glue upper roller 9 prevents the roller from being damaged and the sound generated by contact between the rollers. it can.
[0026]
FIG. 3 shows a perspective view of the glue box and a bearing portion. A perspective view of the glue box B is shown in FIG. Bearing portions 14 a and 14 b are attached to both sides of the paste box B, and the upper glue rollers 9 and 10 and the transfer roller 16 are set. 3B and 3C are views of the bearing portions 14a and 14b as seen from the inside of the paste box B. FIG. The transfer roller 16 is held by bearings 14c and 14d. Since all of the upper glue rollers 9 and 10 and the transfer roller 16 are supported by the bearing portions 14a and 14b, the gap between the rollers can be determined by the shape of the bearing portion. Therefore, the distance between the upper glue roller 9 and the upper glue roller 10 and the distance between the upper glue roller 9 and the transfer roller 16 can be determined by the design of the bearing portion, and a desired distance can be realized.
[0027]
In the above-described embodiment, the example in which the transfer roller 16 is installed between the upper glue roller 9 and the upper glue roller 10 has been described. However, the transfer roller 16 is also provided between the pasting roller 8 and the upper glue roller 10. In this case, even if the gap of the gap b is considerably wide, the paste 3 can be surely transferred to the gluing roller 8 reliably.
[0028]
A 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 are attached to the side wall of the paste box B. However, in the second embodiment, the bearing portions 14a and 14b are not attached to the side wall of the paste box B in the vertical direction. It is configured to allow sliding. Here, in FIG. 4, only the bearing portion 14 a side is illustrated, but the bearing portion 14 b is omitted from illustration because it has a reference shape.
[0029]
A guide member 17 for allowing the bearing portions 14a and 14b to slide in the vertical direction is attached to the side wall of the glue box B as shown in FIG. 4, and the bearing member is formed in a gap formed between the side wall of the glue box and the guide member. Are configured to slide up and down.
[0030]
The glue upper roller 10 is provided with a ring 15 for determining the clearance b in contact with the glue roller 8. The ring 15 is installed in the vicinity of both ends of the glue upper roller 10 so as to have a position that does not affect the transfer of glue and a width that does not affect the glue.
[0031]
A flexure portion 14e is provided below the bearing portion 14a. The flexure portion 14e provides a biasing force for the ring 15 to contact the glue roller 8 when the glue box B is installed. Since the bending portion 14e is bent and the entire bearing portion is to be raised upward in the vertical direction, the thickness of the ring 15 becomes a clearance b, so that a certain gap can be formed between the gluing roller 8 and the gluing roller 10. It is.
[0032]
Since it is 2nd Embodiment as mentioned above, the bearing part, a roller, etc. in a glue box can all be disassembled only by extracting a bearing part upward, and it is easy to wash | clean it at the time of washing | cleaning. In addition, it is possible to construct a fixed gap b without installing a glue box in the gluing machine, and a user-friendly gluing machine can be constructed.
[0033]
【The invention's effect】
As described above, in the wallpaper pasting machine in which two or more glue upper rollers of the present invention are installed in the glue box, glue is transferred regardless of the number of stages of glue transfer using the glue upper roller. A large amount of glue can be transferred to the glue upper roller, and the width of the gap between the glue roller and the glue upper roller that transfers glue to the glue roller can be increased. This makes it easy to adjust the gaps in the gluing operation, and the tolerance is widened against changes in clearance between rollers due to wear of the bearings, etc., and it is possible to reliably apply the glue to the back of the wallpaper. It can be done.
[0034]
In addition, since the bearing portion of the upper glue roller has a single configuration, it can be easily attached and detached.
[0035]
As described above, the adjustment work, which has been a very troublesome work, can be omitted, and the glue can be reliably applied to the back surface of the wallpaper so that a smooth gluing work can be performed.
