Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an adhesive tape applying jig used when applying an adhesive tape to an adherend having a ridge on the surface opposite to the adherend surface.
[0002]
[Prior art]
A thin film may be brought into close contact with the surface of the article to make the article a more desirable design or to add a function to the article. For example, a colorful film is applied to a transparent window of a building to imitate a stained glass or an opaque film to ensure privacy, or a film having an ultraviolet blocking function is attached to an automobile window. It is often done to protect the skin. In addition, since the film can be attached to the article so that the surface of the article can be protected from air (oxygen) and protected, the film application has been increasingly used as a substitute for painting.
[0003]
It is also well known that it is difficult to make a thin film adhere to the surface of an article cleanly. In addition to the difficulty in aligning the film with the article, air often enters between the article and the film and remains as bubbles after the film is applied, which often impairs the aesthetic appearance. Moreover, if it is not applied quickly, a line or streak mark (a so-called shock line) may be attached to a portion where the application work is stopped halfway, but this is also not preferable from an aesthetic point of view. In order to maintain the adhesion of the film to the article for a long period of time, in the case of a film having an adhesive layer on the side in contact with the article, the film needs to be positioned so that the adhesive does not contact the adherend surface. The task of affixing the item to the article with good positional accuracy is even more difficult.
[0004]
For example, in the manufacturing process of an automobile, there is a step of closely attaching a thin film to the surface of an article. More specifically, in the door sash frame 80 of the automobile shown in FIG. 9, the work of applying the black adhesive tape for the purpose of improving the design of the automobile by blackening the outline of the door window. Has been done. The black pressure-sensitive adhesive tape has, for example, a film layer (for example, made of vinyl chloride) as a base material and a pressure-sensitive adhesive layer (for example, an acrylic adhesive) provided on one side of the film layer. In the past, the door sash frame 80 was mainly colored by painting. However, painting has caused environmental impact, and the number of processes and cost are high due to the scattering of solvent and waste liquid. Adhesive tapes having a colored film layer are often used.
[0005]
When sticking black adhesive tape along the door sash frame of an automobile, it is not beautiful if there is a seam, so if the door sash has a curved shape at a part that is easily noticeable, include the curved part. It is preferable to stick with a single long tape. A curved part is the curved part 91 of the door sash frame 80 of the motor vehicle shown in FIG. 9, for example.
[0006]
However, when affixing adhesive tape along the door sash frame of an automobile, if the door sash frame is bent, the adhesive tape cannot be followed and the adhesive tape is displaced from the adherend surface, forcing rework. There was a problem that occurred. In addition, there is a problem that it takes time to position the adhesive tape so that it does not shift in accordance with the curved portion, and a lot of time is required for sticking the adhesive tape. Any problem has been desired to be improved because it reduces productivity and increases production costs.
[0007]
Therefore, in order to solve these problems, a jig useful for applying an adhesive tape has been proposed.
[0008]
For example, according to Japanese Patent Laid-Open No. 2001-123127, an adhesive tape sticking jig that can stick the adhesive tape shown in FIG. 3 stably and accurately at high speed is proposed. The adhesive tape sticking jig 101 sticks the adhesive tape with release paper to the door sash frame 80 while peeling the release paper while moving along the door sash frame 80 of the automobile. The elastic roller 105 for pressing the adhesive tape against the adhesive surface of the frame 80 affixes the adhesive tape without embedding air bubbles, and the guide roller 106 with the concave groove 116 is provided on the door sash frame 80. Adhesive tape It is formed on the back side of the adhesive surface and fits into a ridge 83 (projection) extending along the longitudinal direction of the door sash frame 80, is positioned with high accuracy, and can adhere the adhesive tape with high accuracy. It is said.
[0009]
However, in particular, recent automobile modeling often has a shape in which the contour of the door sash draws a curve with a small radius of curvature, and often curves with a corner instead of a smooth curve. Similarly, the protrusion 83 (projection) extending along the longitudinal direction of the door sash frame 80 is also formed to be bent more sharply or with a corner. In that case, the guide roller 106 with the concave groove 116 becomes unstable because it is difficult to fit into the protrusion 83 (protrusion) due to the difference between the inner and outer rings at the curved portion of the door sash frame 80. As a result, when the adhesive tape is quickly applied at a stretch, the curved portion prevents the adhesive tape from being displaced at the curved portion, or the guide roller 106 with the concave groove 116 does not come off from the protruding portion 83 (convex strip). When trying to pass slowly, there was a problem of entraining bubbles and causing the generation of shock lines.
[0010]
[Problems to be solved by the invention]
The present invention has been made in view of the above-described conventional problems. For example, when an adhesive tape is applied to a door sash frame of an automobile, the contour of the door sash is a curve with a small curvature radius. It is an object of the present invention to provide an adhesive tape application jig that can be applied quickly without entrainment of bubbles or deviation of the tape application position even if it is bent or bent with a corner.
[0011]
The inventors of the present invention, for example, become more difficult to apply the adhesive tape to the outline of the door sash of the automobile, while the detail finish in the appearance of the automobile is also a place where the consumer pays attention and is easily noticeable. Adhesive tape for affixing an adhesive tape to an adherend having an elongated adherend surface and a ridge on the surface opposite to the adherend surface in order to cope with the current situation where it is difficult to allow a seam of the tape to occur As a result of repeated research on the sticking jig, it has been found that the above object can be achieved by the following means.

In other words, it is preferably attached with play. Moreover, it is preferable that the sticking part and the guide part have an opening / closing means that can hold the adherend with elasticity and can remove the sticking part and the guide part from the adherend.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, a preferred embodiment of an adhesive tape attaching jig (hereinafter also simply referred to as a jig) according to the present invention will be described.
[0015]
In the present invention, the chevron-shaped guide roller has a rib-shaped concave groove, and the protrusion on one side of the roller having the protrusion protruding at both ends from the groove bottom surface that is coaxial with the concave groove is removed. A roller with a shape.
[0016]
The adhesive tape sticking jig of the present invention comprises a long adhesive tape, an elongated adherend surface, and a ridge formed on the opposite surface of the adherend surface, for example, in the longitudinal direction of the adherend surface. , An adhesive tape sticking jig that can be attached without taking time so that bubbles do not enter so as not to slip. A more specific adherend will be described with reference to an automobile door sash frame 80 shown in FIG.
[0017]
The door sash frame 80 generally has a cross-sectional shape shown in FIG. 8, and an adhesive tape is pasted on the adherend surface 81 seen from the outside as a substitute for painting. A weather strip is attached to the rear surface 82 side of the door sash frame 80 opposite to the adherend surface 81, and a ridge 83 is provided on the rear surface 82 of the door sash frame 80 as a rib for fixing the weather strip. It is formed. As shown in FIG. 9, the door sash frame 80 has a portion formed by a straight line and a portion (curved portion 91) configured by a curve, and the curved portion 91 adheres to the adherend surface 81. It has been difficult in the past to easily and quickly apply a tape with good positional accuracy, but according to the present invention, it is possible.
[0018]
FIG. 1 is a perspective view showing an embodiment of the adhesive tape attaching jig of the present invention. The adhesive tape sticking jig 1 includes, for example, a sticking portion 5 composed of a tape guide roller 13 and a press roller 15 for pressure-bonding the adhesive tape to the adherend surface 81 of the door sash frame 80 shown in FIGS. A guide portion 6 comprising chevron-shaped guide rollers 16 and 17 that contact the protrusion 83 of the adherend 81 and sandwich the adherend 81 together with the sticking portion 5 and guide the jig itself along the protrusion 83; Have. And the guide part 6 is equipped with the mountain-shaped guide roller 17 of both ends toward the top in one direction, and the mountain-shaped guide roller 16 at the center is equipped with the top toward the other direction. The two auxiliary rollers 27 are in contact with the weather strip mounting portion of the door sash frame 80 and support the adhesive tape attaching jig 1. And when the adhesive tape sticking jig | tool 1 moves along the protrusion part 83, the auxiliary | assistant roller 27 rotates and it contributes to the stability at the time of the movement of the adhesive tape sticking jig | tool 1. FIG.
[0019]
As shown in this adhesive tape sticking jig 1, the present invention is characterized in that, in the guide portion, the chevron-shaped guide rollers at both ends and the other chevron-shaped guide rollers are mounted facing in opposite directions. Have. Preferably, the chevron-shaped guide rollers other than both ends are provided so as to be swingable in the central axis direction.
[0020]
This characteristic portion will be described with reference to FIGS. 6 (a), 6 (b), 7 (a), and 7 (b) in comparison with a conventional jig. 6 (a) and 6 (b) show how the angled guide rollers 16 and 17 are in contact with the protrusion 83 of the door sash frame 80 when the adhesive tape attaching jig 1 according to the present invention is used. In the drawing, parts other than the guide roller of the jig are omitted. 6A is a view of the mountain-shaped guide roller 16 and the door sash frame 80 as viewed from the direction facing the cross section of the door sash frame 80, and FIG. 6B is a view as viewed from the direction of facing the back surface 82 of the door sash frame 80. It is. Similarly, in FIGS. 7A and 7B, when a jig provided with the conventional guide roller 106 with the recessed groove 116 is used, the protruding groove 83 of the door sash frame 80 has the recessed groove 116. The guide roller 106 is in contact with the jig, and portions other than the guide roller of the jig are omitted. FIG. 7A is a diagram viewed from the direction facing the cross section of the door sash frame 80, and FIG. 7B is a diagram viewed from the direction facing the back surface 82 of the door sash frame 80. In both the adhesive tape attaching jig 1 according to the present invention and the conventional jig, the guide roller is elastic in the direction (indicated by the arrow R in the figure) in contact with the ridge portion by other means not shown. It is pressed by holding.
[0021]
In the conventional jig, as is understood from FIG. 7A, the groove 116 of the guide roller 106 is fitted into the protrusion 83 of the door sash frame 80, and the guide roller 106 is aligned with the protrusion 83. Move along and guide the jig itself. Therefore, as shown in FIG. 7B, when the ridge 83 is linear, the ridge 83 contacts the groove 116, and the guide roller 106 moves smoothly along the ridge 83. However, when the ridge 83 is curved, the direction of the groove 116 of the guide roller 106 does not match the direction of the ridge 83, and the ridge 83 is in contact with the bottom of the groove 116. As a result, the guide roller 106 becomes unstable. When the ridge 83 draws a curve with a small radius of curvature, the guide roller 106 may be removed from the ridge 83.
[0022]
According to the present invention, such a problem cannot occur. In the adhesive tape sticking jig 1 according to the present invention, the guide roller of the guide portion 6 in contact with the ridge 83 is not a guide roller with a concave groove as in the prior art, but a mountain having an inclination from the bottom to the top. A type of guide roller is used. That is, in the pressure-sensitive adhesive tape sticking jig 1 according to the present invention, one mountain-shaped guide roller is not fitted to the protrusion, and is pressed in the direction indicated by the arrow R (FIG. 6). (A)), for example, the displacement of the door sash frame toward the bottom surface of the mountain-shaped guide roller, that is, the downward direction in FIG. 6A (the jig itself is the opposite direction, that is, the top of the mountain-shaped guide roller. Displacement only in the direction), and only one mountain-shaped guide roller cannot stably move along the ridge 83.
[0023]
As shown in FIG. 6 (b), the guide portion 6 includes three mountain guide rollers 16 and 17, and the mountain guide rollers 17 at both ends face the top in one direction (downward in the drawing). It is important that the central mountain-shaped guide roller 16 is provided with the top facing in the other direction (upward in the drawing). With such a configuration, the adhesive tape provided with the door sash frame 80 provided with the ridge 83 and the mountain guide rollers 16 and 17 where the ridge is formed linearly or where the ridge is bent. The fluctuation in the vertical direction in FIG. 6 (b) with the sticking jig 1 itself can be suppressed by the three mountain guide rollers 16, 17, and the adhesive tape sticking jig 1 can be stably and smoothly along the protrusion. Can move.
[0024]
Only two mountain guide rollers facing in opposite directions are not preferable because straight running stability cannot be maintained. On the other hand, when it is composed of four chevron-shaped guide rollers, for example, when the chevron-shaped guide rollers at both ends and the two chevron-shaped guide rollers between them are provided in opposite directions, the straight running stability increases. As with the conventional jig, the ability to cope with the curved portion is reduced, and the mountain-shaped guide roller is undesirably removed.
[0025]
Moreover, in the adhesive tape sticking jig 1 according to the present invention, the center chevron-shaped guide roller 16 can be swung in the center axis direction, that is, the S direction in FIG. It is preferable that it is provided. The ability to cope with the curved portion is further improved, and the mountain-shaped guide rollers 16 and 17 are separated from the ridge 83 even if the door sash has a curved shape with a small radius of curvature or is bent at a corner. This is because the adhesive tape sticking jig 1 can move stably without contact.
[0026]
For example, when a tape is applied to the door sash frame 80 using the adhesive tape application jig 1 according to the present invention, the protrusion 83 as shown in FIG. When the ridge 83 moves to a curved line, the central mountain-shaped guide roller 16 moves upward (direction S1 in the drawing) along the central axis. Accordingly, the contact between the mountain guide rollers 16 and 17 and the protruding portion 83 is further ensured, and the adhesive tape attaching jig 1 can move stably along the protruding portion 83.
[0027]
4, 5, 6 (b) and the like, in the adhesive tape attaching jig 1 according to the present invention, the mountain-shaped guide roller is in the direction from the bottom to the top in the figure. However, the present invention is not limited to this embodiment. The adhesive tape sticking jig 1 preferably corresponds to the right turn of the ridge portion (the bending direction indicated by the ridge portion 83 in FIG. 5), and if the ridge portion bends in the opposite direction to FIG. For example, the mountain-shaped guide roller is preferably attached so that the direction from the bottom surface to the top is up, down, and up.
[0028]
Further, the present invention does not limit the shape of the mountain-shaped guide roller. A mountain-shaped guide roller having a preferable shape can be selected according to the curve drawn by the ridges, as long as it has a mountain shape, that is, a slope whose horizontal cross-sectional area decreases from the bottom surface to the top. For example, a mountain-shaped guide roller having a shape whose side surfaces are shown in FIGS. 10A is a chevron-shaped guide roller having a generally truncated cone shape, and FIG. 10B is a chevron-shaped guide roller having a shape in which a cylinder is mounted on the truncated cone (FIGS. 6A and 6B). ) Etc.), FIG. 10 (c) is a shape in which a cylinder is placed on a truncated cone like FIG. 10 (b), and a protrusion protruding from the groove bottom surface that is coaxial with the concave groove having a rib shape. This is a mountain-shaped guide roller having a flange shape and a gentle slope of the truncated cone. 10 (d) has the same flange shape as FIG. 10 (c), and the slope of the truncated cone has a gentle slope, but the inner side of the flange, that is, the groove bottom side is thinner on the outer peripheral side. A chevron-shaped guide roller that gradually increases in thickness toward the axis up to the portion where the cylinder is placed on the truncated cone, and that has a uniform thickness on the inner side (axis side) from the cylinder portion.
[0029]
Hereinafter, with reference to drawings, the whole including the said characteristic part of the adhesive tape sticking jig of this invention is demonstrated still in detail.

Due to the action of the coil spring 8, the press roller 15 of the sticking portion 5 provided in the first support member 2 and the mountain-shaped guide rollers 16, 17 of the guide portion 6 provided in the second support member 3 approach each other, and the door sash frame 80. Pinch.
[0032]
As can be understood from FIG. 2A, two tape guide rollers 13 are pivotally attached to the first support member 2 with a press roller 15 interposed therebetween. The tape guide roller 13 can guide the adhesive tape 41 to the pressing surface 14 of the press roller 15 separately from the release liner 42, and also regulates the deviation in the width direction of the tape to stably provide the adhesive tape 41. Is sent to the press roller 15. The adhesive tape 41 is fed along the surface of the press roller 15, and when the feeding path of the adhesive tape 41 is reversed by the tape guide roller 13, the release liner 42 is detached from the film and the adhesive layer 43, and the film and The pressure-sensitive adhesive layer 43 is pressed against the adherend surface of the door sash frame 80 by the pressing surface 14 of the press roller 15.
[0033]
In addition to the mountain-shaped guide rollers 16 and 17, the second support member 3 is preferably provided with an auxiliary roller 27 that abuts on a weather strip mounting portion 84 that protrudes toward the back surface side of the door sash frame 80. When the auxiliary roller 27 comes into contact with the weather strip mounting portion 84 of the door sash frame 80, the adhesive tape attaching jig 1 is sandwiched between the door sash frames 80 and the adhesive tape is applied. 1 is prevented, and the stability of the adhesive tape sticking jig 1 is improved.
