Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an automatic wallpaper glue for positioning a curing tape that forms a curing part for layering on a sheet-like wall covering material at a predetermined position when it is laminated along the edge of the glued sheet-like wall covering. The present invention relates to a curing tape guide for attached machines.
[0002]
[Prior art]
As an interior finish of a building, a sheet-like wall covering made of various materials such as paper, cloth, resin, metal, tile, and so-called wallpaper is pasted on the wall surface. The wall paper is usually rolled into a roll and cut into a predetermined size while being continuously glued to the back using an automatic wall paper glue machine. Is what you do.
[0003]
In a general automatic wallpaper pasting machine, as shown in a side perspective view of FIG. 3, a plurality of rolls (15 to 22) are arranged in the upper structure 12 and the lower structure 13 constituting the pasting machine main body 111, respectively. They are arranged via gears, and can be transported by each roll by sandwiching wallpaper between the upper and lower body structures. In the lower structure 13, there is provided a glue pad 14 that contains glue.
[0004]
In the upper structure 12, an upper pinch roll 15 constituting a pinch roll for taking the wallpaper 1 drawn from the roll-shaped raw fabric into the pasting machine main body 11 from the rear side and the pasting machine main body 11 on the wallpaper 1. The drive roll 17 for applying the feed tension in the front direction of the paper and the press roll 16 that rotates following the wallpaper 1 while pressing the wallpaper 1 between the two rolls are arranged in parallel with each other at a predetermined interval. In addition, each is pivotally supported on a side plate of the upper structure 12.
[0005]
Further, in the lower structure 13, a lower pinch roll 18 that forms a pair with the upper pinch roll 15 and a glued roll for applying the glue transferred from the glue raising roll 20 to the back surface of the wallpaper 1. 21, a doctor roll 19 that adjusts the amount of glue in contact with the gluing roll 21, and a leveling roll 22 that applies an appropriate tension to the wallpaper 1 together with the drive roll 17 and feeds it in the front direction with a predetermined distance from each other. It is pivotally supported on the side plate of the lower structure 13 so as to be arranged in parallel. The glue raising roll 20 is pivotally supported on both inner side surfaces of the glue basket 14.
[0006]
In the automatic wallpaper pasting machine having the above-described configuration, the wallpaper 1 taken in from the rear side and conveyed onto the front glue roll 21 by the pinch rolls (15, 18), where the glue is applied to the back surface is as follows. Further, it is sent out to the front by a drive roll 17 and a leveling roll 22.
[0007]
On the other hand, in the work of pasting wallpaper on the wall surface, the “overlapping” construction method is generally employed. “Overlap” means that when two wallpapers are spliced together on the wall, the two wallpapers are attached to the wall with the edges overlapped, and the paste is almost centered before the glue dries. Cut the edges of both wallpaper together through the blade, peel off the cut edge of the overlapping part of the lower wallpaper, and paste the upper wallpaper on the wall where the peeled edge part was (upper This is a construction method in which adjacent wallpaper is peeled off continuously.
[0008]
In wallpaper that performs such “overcutting”, the surface of the lower edge of the wallpaper is not glued, making it easy to separate the upper and lower wallpaper edges after cutting, and sticking to the wall. In order to maintain the adhesive ability of glue on the edge of the upper wallpaper, a curing portion is formed by laminating curing tape along the edge of the glued surface (back surface) of the wallpaper. .
[0009]
Lamination of the curing tape to the wallpaper pasting surface is also performed in an automatic wallpaper pasting machine. For example, as shown in FIG. 3, the curing tape 2 drawn out from the tape roll disposed below the glue pad 14 is introduced from the front side of the glue pad 14 to the lower side of the leveling roll 22, and the drive roll 17. When the wallpaper 1 that has been applied with the glue from the glued roll 21 and passed between the drive roll 17 and the leveling roll 22 is passed between the leveling roll 22 and the leveling roll 22, Are sent out together in a stacked state.
[0010]
In order to position the curing tape 2 so as to be laminated along the edge of the wallpaper 1, a tape guide 103 as shown in FIG. This is equipped with a latching portion 104 having a reverse U-shaped cross section at a position corresponding to one or both of the left and right edges of the wallpaper 1 on the upper front side of the glue pad 14 and the curing tape 2 These are provided with a guide portion 105 that guides the left and right edges in a sliding state with gripping pieces (105x, 105y) bent so as to be held from both sides.
[0011]
[Problems to be solved by the invention]
Usually, the cutting of the wallpaper 1 in which the paste is applied to the back surface and the curing tape 2 is laminated and sent out is performed in a state where the wallpaper is in contact with the front surface of the paste pad 14 and temporarily fixed, and the paste pad stay 23 at the lower part of the main body. It is cut by hand with a cutter using the upper surface of the ruler.
[0012]
However, in the conventional tape guide 103 as described above, since the guide portion 105 protrudes to the front side of the glue pad 14 by the thickness thereof, when the wallpaper 1 is brought into contact with the front face of the glue pad 14 at the time of cutting, FIG. That part will swell as you can see. When the wallpaper 1 is cut along the paste stay 23 in such a partially swelled state, the actual cut edge is not a straight line perpendicular to the longitudinal direction of the wallpaper 1, but is inclined or distorted. The obtained wallpaper piece has a problem that the length dimension is not uniform in the width direction.
[0013]
Such a non-uniform length dimension in the width direction occurs every time cutting is performed, and therefore when the wallpaper 1 is applied to the wall surface, the length is partially insufficient or protrudes. Therefore, in some cases, it is necessary to cut the edge portion of the cut wallpaper 1 again, and it is necessary to increase the length dimension in advance, which increases unnecessary time and waste of wallpaper. Work efficiency.
[0014]
In view of the above problems, an object of the present invention is to obtain a curing tape guide for an automatic wallpaper pasting machine that does not adversely affect the cutting size of the wallpaper.
[0015]
[Means for Solving the Problems]
In order to achieve the above object, in the curing tape guide for an automatic wallpaper pasting machine according to the first aspect of the present invention, the sheet-like wall covering is brought into contact with the pasting roller while being fed forward from the rear part of the main body. Glue provided below the gluing roll in the automatic wallpaper gluing machine that continuously glues the back of the wall covering material to accommodate the glue transferred to the gluing roll via the gluing roll. Curing for an automatic wallpaper pasting machine that positions the curing tape, which is laminated along the edge of the glued sheet-like wall covering and forms the curing part for lap cutting, in the width direction of the sheet-like wall covering In the tape guide, an engaging portion having a reverse U-shaped cross section that sandwiches the upper end of the front side of the glue pad, and extends from the top of the locking part to the rear side of the glue pad, and on the right and left sides of at least the curing tape. Bent grip to guide one edge Guide portion having, those with and.
[0016]
In the curing tape guide according to the present invention, a guide portion is formed so as to extend from the top of the locking portion having an inverted U-shaped cross section attached to the upper end of the front side of the glue pad to the rear side of the glue pad. For this reason, the thick guide portion does not protrude forward when the glue paste is attached.
[0017]
Therefore, unlike the conventional tape guide, it is possible to improve the work efficiency by eliminating the troubles such as recutting and waste of the wallpaper without causing the wallpaper to swell at the time of cutting to make the cutting size non-uniform.
[0018]
Furthermore, according to the configuration of the curing tape guide of the present invention, since the exit end of the guide portion that actually guides the curing tape is close to the leveling roll 22, the distance from the positioning of the curing tape to the leveling roll 22 is increased. Since the shortening and the meandering of the curing tape after passing through the guide are greatly reduced, stable guidance of the curing tape is realized.
[0019]
The curing tape guide according to the present invention may have only one grip piece on the guide portion so as to guide only one of the left and right edges of the curing tape. It is desirable to guide both edges because a more stable guide can be achieved.
[0020]
Moreover, it is good also as a structure which enables change of the relative distance of a pair of right and left gripping pieces, and selects the distance between gripping pieces according to the size of the curing tape to be used. For example, the relative distance of the gripping pieces can be changed by dividing the tape guide into two left and right members and allowing the tape guide to slide on the upper edge of the front surface of the glue paste.
[0021]
Further, the locking portion having an inverted U-shaped cross section of the present invention only needs to have a clamping force enough to fix the tape guide to the upper end of the glue pad so that the latching position does not shift during the tape guide, For example, the sandwiching interval is set to be approximately the same as the thickness of the glue wall, and in the sandwiched state of the glue wall, it is difficult to cause a positional shift due to the frictional force between the two. Further, if the locking portion is a spring type, a more stable fixed state can be obtained. Of course, a detachable fixing jig that firmly fixes both may be used.
[0022]
DETAILED DESCRIPTION OF THE INVENTION
1 and 2 show a tape guide provided with a pair of left and right grip pieces as a curing tape guide for an automatic wallpaper pasting machine according to an embodiment of the present invention. FIG. 1 is a side perspective view showing a schematic configuration of an automatic wallpaper pasting machine in a state where a tape guide according to the present embodiment is mounted, and FIG. 2A is a partially enlarged view in the vicinity of a tape guide mounting portion (b) ) Is a perspective view of the tape guide.
[0023]
The tape guide 3 according to the present embodiment includes an engaging portion 4 having an inverted U-shaped cross section for sandwiching the upper end of the front side of the glue pad 14 when the automatic wallpaper pasting machine is mounted, and the engaging portion 4 from the top of the head. The guide portion 5 extends rearward at an inclination angle of about 100 degrees with respect to the extending direction.
[0024]
On the upper surface of the guide portion 5, a pair of left and right grip pieces (5x, 5y) for guiding the left and right edges of the curing tape in a sliding state are formed. When the tape guide 3 is fixedly equipped at a position corresponding to the edge running position of the wallpaper 1 during the pasting operation of the glue pad 14 by holding the predetermined position of the upper end on the front side of the glue pad 14 with the locking part 4. The extending direction of the guide part 5 is just toward the lower end of the leveling roll 22, and the tip of the guide part 5 comes to a position very close to the leveling roll 22.
[0025]
When starting the gluing operation on the wallpaper 1 by the gluing machine, the initial setting for setting the wallpaper 1 on the gluing machine main body 11 is carried out through the tape guide 3 in the above-mentioned mounting state. Setting is also done.
[0026]
That is, in the initial setting, the upper structure 12 is opened with respect to the lower structure 13, and first, the leading end of the curing tape 2 is pulled out from the tape roll disposed below the glue pad 14, and the upper end is opened from the front side of the glue pad 14. After passing through the inside of the pair of gripping pieces (5x, 5y) by the guide part 4 of the tape guide 3 provided in the part, the tape is inserted into the main body from the lower side of the leveling roll 22, and is applied to the surface of the leveling roll 22. It is pulled up to the upper surface side along, and it puts on the leveling roll 22 so that it may hang down to the front surface of the main body.
[0027]
Next, the leading edge of the wallpaper 1 that is adjusted to a predetermined width through a slitter 10 attached to the rear part of the gluing machine main body 1 is pulled out from the roll and the wallpaper 1 so that the leading edge hangs down on the front side of the main body. Is placed on the lower pinch roll 18, the glued roll 21, and the leveling roll 22, and the upper structure 12 is closed on the leveling roll 22 with the edge of the wallpaper 1 overlapped on the curing tape 2. The sandwiched state of the curing tape 2 is obtained.
[0028]
Next, the initial operation of the gluing machine is performed. When the initial operation is started, by the rotational driving of each roll, the glue raising roll 20 transfers the glue to the glued roll 21 while transferring the glue in the glue basket 14, and is transferred to the surface of the glued roll 21. The glue is adjusted to a predetermined amount by the doctor roll 19, and a stable amount of glue is uniformly attached to the surface of the glued roll 21.
[0029]
On the other hand, although the wallpaper 1 is also conveyed forward by the rotational drive of each roll, the glue is not attached to the surface of the glued roll 21 at the beginning in the middle of contact with the glued roll 21, and the glue raising roll Although the amount of glue attached gradually increases due to the transfer from 20, the amount of glue on the back surface of the wallpaper 1 is insufficient until a sufficient amount of glue is stably transferred to the surface of the glue roll 21. Therefore, the wallpaper 1 and the curing tape 2 sent through the drive roll 17 and the leveling roll 22 are also in an unstable adhesive state at a predetermined length from the tip.
[0030]
When the wallpaper on which the glue adheres to the wallpaper 1 is stable, is sufficiently glued to the back surface, and the curing tape 2 is in a stable state begins to be fed out from the front of the main body, the initial operation is stopped and the tip is glued. An unnecessary portion whose amount is insufficient and the adhesive state with the curing tape 2 is unstable is cut off with a cutter, and the initial setting is completed.
[0031]
At this time, the wallpaper 1 is temporarily abutted on the front surface of the glue pad 14, and the upper surface of the stay 23 is used as a ruler and cut along the cutter. Therefore, the cut edge at the tip of the first wallpaper 1 is linear.
[0032]
After the initial setting is completed, the main operation is started. Sequentially coated with paste, the wallpaper 1 sent from the front surface of the main body 11 through the drive roll 17 and the leveling roll 22 is overlaid with the curing tape 2 along its edge. The wallpaper 1 with the curing tape 2 that is continuously glued and sent out is cut with a cutter with a desired length and stopped when a desired number of wallpaper pieces are obtained.
[0033]
Further, when each wallpaper piece is cut, the tape guide 3 protrudes to the front and partially covers the wallpaper 1 when the wallpaper 1 is temporarily abutted against the front surface of the glue pad 14 in the same manner as the initial cutting. Therefore, the wallpaper 1 is not wasted because the cut ends at the both ends of each wallpaper piece are straight and the length in the width direction is uniform.
[0034]
Further, since the curing tape 2 abuts on the surface of the leveling roll 22 almost immediately after passing through the guide portion 4, there is no meandering of the curing tape 2 and the drive roll 17 of the curing tape 2 and the leveling roll. Since the superposition of the wallpaper 1 on the wallpaper 1 always proceeds under stable positioning, the laminated state of the obtained tape 2 on the curing tape 2 is always along the edge.
[0035]
【The invention's effect】
As described above, the curing tape guide of the present invention has a guide portion that does not protrude to the front surface of the pasting machine body, so that the length of the wallpaper is always uniform in the width direction without adversely affecting the cutting of the wallpaper. This eliminates the need for recutting and waste of wallpaper, thereby improving work efficiency.
