Description

 Adhesive Tape Application Tool {ADHESIVE TAPE APPLICATION TOOL}

The present invention relates to a method and apparatus for applying an adhesive tape, and more particularly, to an adhesive tape application tool usable when the adhesive tape is applied to an adherend having a protruding line portion on a surface opposite the application surface of the adhesive tape.

 Thin films are attached to the surface of the product to give the product a preferred design or add some functionality. By way of example, a colored film that can be matched with stained glass or a protective opaque film can be attached to the transparent window of the building, or a UV sunscreen film is attached to the window of the vehicle to protect the passenger or driver's skin. . Since applying the film to the article can protect the surface from air (oxygen), it is preferred to apply the film instead of providing a coating.

It is known in the art to apply a thin film to the surface of an object cleanly. One of the reasons is that it is difficult to precisely position the film on the object. Another reason is the penetration of air between the object and the film. The air remains bubbles after application of the film, which deteriorates the appearance. If the application operation is not completed quickly, a line mark (break line) may be formed in the area where the application operation is stopped, which may damage the appearance. If the film has an adhesive layer on the side that contacts the object, the film should be positioned so that the adhesive does not come into contact with the application surface to maintain the adhesion of the film to the object for a considerable time. This requirement makes it difficult to apply a clean and accurate film to the object.

By way of example, some automotive assembly lines have a step of applying a thin film (eg, a narrow width paint replacement film) onto an automotive surface. Particularly as an example, in the door chassis frame 80 of the vehicle shown in Fig. 9, a black adhesive tape (i.e. an adhesive-cured paint replacement film) provides the design of the vehicle by providing a window outline line of the door black. Is applied to improve it. By way of example, the black adhesive tape includes a film layer (eg, made of vinyl chloride) as a substrate and an adhesive (eg, acrylic type pressure sensitive adhesive) provided on the back side of the film layer. In the past, the door chassis frame 80 has been colored with a conventional paint coating. However, coating operations increase the environmental burden of solvent spraying and the resulting liquid waste, requiring a significant number of process steps and operating costs. For this reason, in recent years, adhesive-curable tapes having a layer of colored film (ie, adhesive-curable paint replacement film) have become popular.

The seam damages the appearance when black adhesive tape is applied along the door chassis frame of the vehicle. Thus, when the door chassis has a contoured shape with bends in a prominent position, it is desirable that a long piece of tape be applied along the area comprising the curved surface. The curvature in this specification refers to the curvature 91 of the door chassis frame 80 of the vehicle shown in FIG. 9 by way of example.                 

However, when the adhesive tape is applied along the door chassis frame of the vehicle, the application operation may not follow the curved portion of the door chassis frame. The adhesive tape may deviate from the application surface, which requires starting the application operation again from the beginning. Another problem is that the adhesive tape application operation requires considerable time because the adhesive tape cannot be properly positioned along the curve in a short time. As all of the above problems reduce productivity and increase costs, an improvement in this technique is required.

To solve the above problems, a tool has been proposed that can be used to apply adhesive tape.

As an example, Japanese Patent Application Laid-Open No. 123127/2001 proposes the adhesive tape application tool shown in Fig. 3, which can apply the adhesive tape constantly and precisely at high speed. The adhesive tape application tool 101 applies the adhesive tape with the release paper to the door chassis frame 80 and removes the release paper by moving the tool along the door chassis frame 80 of the vehicle. The adhesive tape may be applied without bubbles therein because the tool is provided with an elastic roller 105 which presses the adhesive tape against the door chassis frame 80. In addition, a guide roller 106 having a concave groove 116 is formed on the back side of the tape application surface of the door chassis frame 80. The guide roller 106 engages the protruding line portion 83 (convex portion) extending longitudinally along the door chassis frame 80, and high precision positioning is ensured. In this way, the tool can apply the adhesive tape accurately.                 

However, many modern vehicle designers prefer curved structures with corners rather than small radius curves or smooth curves in door chassis structures. This necessitates a protruding line portion 83 (convex) extending longitudinally along the door chassis frame 80 which is formed with a sharp bend or corner. In this example, the guide roller 106 having the concave groove 116 can engage the protruding line portion 83 (convex portion) at the curved portion of the door chassis frame 80 due to the inner-outer ring difference. Therefore, if the adhesive tape is stretched and applied, deviation of the adhesive tape may occur at the curved portion, and the tool derails the guide roller 106 having the concave groove 116 from the protruding line portion 83 (convex line). If moved slowly so as not to derail, the adhesive tape may contain bubbles that break the line.

The present invention has been considered from the viewpoint of the above situation, and can be used to apply the adhesive tape to the door chassis frame of the vehicle and there is no bubble generation even when there is a small radius curved portion or a sharp curved portion where the door chassis has an edge, It is an object of the present invention to provide an adhesive tape application tool that can be applied quickly without misalignment.

As the design changes to the door chassis structure of the vehicle and the consumer's desire for the details of the exterior of the vehicle become more stringent, the application of adhesive tape becomes more and more difficult, as the seam of adhesive tape is forbidden in the visible areas. In view of the losing situation, the inventors have conducted extensive research for the development of an adhesive tape application tool for applying an adhesive tape on a deposit having a long narrow application surface and a line portion protruding on the back side of the application surface. As a result, the inventors achieved this object by the following means.

In particular, the present invention provides an adhesive tape application tool for applying a long adhesive tape in the longitudinal direction of an application surface to an adherend having a long application surface and a protruding line portion formed on the back side of the application surface. The adhesive tape application tool includes three guide rollers (eg, mountain tape guide rollers) having an adhesive tape and a tapered portion, and an application portion for pressing against the guide portion, the guide rollers being with the application portion. By contacting the protruding line portion in a manner of forcing the adherend, the guide portion has a guide roller having a tapered shape portion located at both ends and provided with the upper ends of the guide rollers oriented in one direction, and the upper end portion is different from the guide roller. Another guide roller (located in the center) having a tapered shape provided oriented in a direction is provided.

In the present invention, it is preferable that the center guide roller having the tapered shape is swingably installed in the direction of the center axis. In other words, it is preferable that the guide roller having a tapered shape is provided with a slight margin. In addition, it is preferable that the adherend is elastically pushed down by the application portion and the guide portion, and an opening and closing means for releasing the application portion from the adherend is provided.

Preferred embodiments of the adhesive tape application tool of the present invention (hereinafter simply referred to as "tool") are described.

In the present invention, the guide roller having the tapered shape has a concave groove having a configuration in which ribs are formed therein and protruding line portions protruding from the bottom surface of the grooves provided coaxially, and protruding line portions on one side of the roller are removed. Reference is made to the provided roller.

The adhesive tape application tool of the present invention is for applying the long adhesive tape on the adherend having the long application surface and the protruding line portion formed on the back side of the application surface without bubbles in the longitudinal direction of the application surface and without deviation of the tape application position. The door chassis frame 80 of the vehicle shown in Fig. 9 can be described as a special example of the adherend.                 

In general, the door chassis frame 80 has a cross section shown in FIG. Instead of coating, an adhesive tape is applied to the application surface 81 which can be seen from the outside. A weather strip is attached to the back side 82 on the opposite end of the application surface 81 of the door chassis frame 80. The protruding line portion 83 is formed on the rear surface 82 of the door chassis frame 80 as a rib for fixing the weather strip. As shown in Fig. 9, the door chassis frame 80 has portions formed by straight lines and curves (curves 91). In the past, it has been difficult to apply the adhesive tape to the curved portion 91 of the application surface 81 easily, quickly, and with good aesthetics. The present invention solves this problem.

1 is a perspective view showing one embodiment of the adhesive tape application tool of the present invention. The adhesive tape application tool 1 uses a tape guide roller 13 and a pressure roller 15 to adhere the adhesive tape to the application surface 81 of the door chassis frame 80 shown in Figs. 8 and 9 by way of example. And the guide portion 6 has guide rollers 16 and 17 having tapered shapes, which together with the applicator 5 grip the tool along the protruding line portion 83 while gripping the application surface 81. It contacts the protruding line portion 83 of the application surface 81 to guide. The guide portion 6 has a guide roller 17 having a tapered shape portion located at both ends and provided with the upper end oriented in one direction, and a center guide roller 16 having a tapered shape portion provided with the upper end oriented in a different direction. ) Is provided. In addition, two auxiliary rollers 27 are provided to contact the applicator for the weather strip of the door chassis frame 80 and press down the adhesive tape application tool 1. When the adhesive tape application tool 1 moves along the protruding line portion 83, the auxiliary roller 27 is rotated, contributing to stabilization of the adhesive tape application tool 1 during movement.

In this adhesive tape application tool 1 as shown, the present invention is characterized in that the guide rollers having tapered shapes are provided at both ends and the other guide rollers having tapered shapes are installed in opposite directions to each other. It is preferable that the guide roller which has a taper-shaped part is provided in the swinging direction of a center-axis direction except the both ends.

This feature is explained in comparison with the conventional tool with reference to FIGS. 6A, 6B, 7A and 7B. 6A and 6B show that when the adhesive tape application tool 1 of the present invention is used, a guide roller having tapered shapes 16 and 17 is formed with the protruding line portion 83 of the door chassis frame 80. The way of contact is shown. The part of the tool except for the guide roller is omitted. FIG. 6A shows a guide roller having a tapered shape 16 and a door chassis frame 80 shown in the direction toward the cross section of the door chassis frame 80, and FIG. 6B is a door chassis frame 80. FIG. Similar view shown in the direction towards the back side 82 of FIG. In a similar manner, FIGS. 7A and 7B show that when a conventional tool with a guide roller 106 having a concave groove 116 is used, the guide roller 106 having a concave groove 116 is used as a door chassis frame ( The manner of contact with the protruding line portion 83 of 80 is shown. The part of the tool except for the guide roller is omitted. FIG. 7A is a view in the direction toward the cross section of the door chassis frame 80, and FIG. 7B is a similar view in the direction toward the back surface 82 of the door chassis frame 80. In both the adhesive tape application tool 1 and the conventional tool of the present invention, the guide roller is elastically pressed in the direction of contact with the protruding line portion (direction indicated by the arrow R in the drawing) by means not shown in the drawings. do.

As can be seen from FIG. 7A, the recessed groove 116 of the guide roller 106 allows the guide roller 106 to move along the protruding line portion 83 to guide the tool as a whole. Coupling the protruding line portion 83 of the chassis frame 80. Therefore, when the protruding line portion 83 is straight as shown in FIG. 7B, the concave groove 116 contacts the protruding line portion 83 and the guide roller 106 is the protruding line portion 83. It can be moved smoothly along. However, when the protruding line portion 106 is curved, the concave groove 116 of the guide roller 106 does not coincide with the direction of the protruding line portion 83. The protruding line portion 83 cannot come into contact with the bottom of the concave groove 116 and remains floating, thus preventing a stable slide of the guide roller 106. When the protruding line portion 83 has a small radius of curvature, the guide roller 106 sometimes shifts the protruding line portion 83.

This problem can be avoided using the tool of the invention. In the adhesive tape application tool 1 of the present invention, a guide roller having a tapered shape having an inclined portion from the bottom toward the top thereof is in contact with the protruding line portion 83 instead of the guide roller having a conventional concave groove ( 6) is used as the guide roller. In the adhesive tape application tool 1 of the present invention, one guide roller having a tapered shape does not engage the protruding line portion. Even when the guide roller having the tapered shape is pressed in the direction shown by the arrow R in Fig. 6A, the guide roller has the deflection of the door chassis frame downward, that is, the guide roller having the tapered shape in Fig. 6A. Bias pressurization of the door chassis frame in the direction to the bottom (in other words, for example, deflection with respect to the opposite side or top of the guide roller having a tapered shape as the tool itself). The tool cannot move along the protruding line portion 83 in a stable manner using only one guide roller having a tapered shape.

As shown in Fig. 6B, the guide portion 6 is provided with guide rollers 16, 17 having tapered shapes. The guide rollers 17, which are positioned at both ends and have a tapered shape, are installed with their upper end oriented in one direction (downward in the drawing), and the center guide roller 16 with the tapered shape has the other end (Fig. In the upper direction). This configuration is a swing of the door chassis frame 80 provided with the protruding line portion 83 and the adhesive tape application tool 1 provided with the guide rollers 16, 17 having the tapered shape in the vertical direction shown in Fig. 6B. This is suppressed by the three guide rollers 16, 17 having tapered shapes in both the straight line portion and the curved line portion of the protrusion line portion, whereby the adhesive tape application tool 1 is projected line. Ensures smooth and consistent movement along wealth.

Providing only two guide rollers with tapered features in opposite directions is undesirable because in this configuration it is difficult to ensure straight slide stability. On the other hand, if, for example, the tool has four guide rollers with tapered features, the guide rollers with tapered features located at both ends and the two rollers with one tapered feature positioned therebetween are opposed. When installed in the direction, the guide rollers with tapered features may not operate properly in the curve, and may escape the grooves as in the case of conventional tools, even though the linear sliding stability can be improved.

In the adhesive tape application tool 1 of this invention, it is preferable that the center guide roller which has the taper-shaped part 16 is provided swingably with respect to the center axis direction, ie, the arrow S direction of FIG. 6B. In other words, it is preferable that the center guide roller having the tapered shape 16 be installed with any margin. Such a configuration can improve workability at the curved portion. Even when the door chassis has a curved shape with a small radius or abrupt curve at the corners, the adhesive tape application tool 1 retains the tapered features 16 and 17 that remain in contact with the protruding line portion 83. It can be moved stably by the guide roller provided.

By way of example, when applying the tape to the door chassis frame 80 using the adhesive tape application tool 1 of the present invention, the center guide roller having the tapered shape 16 protrudes as shown in FIG. As shown in FIG. 5, when the tool line 83 moves to the area | region in which the protrusion line part 83 is a curved part, it moves upward along the center axis (SI direction in drawing) as shown in FIG. This arrangement allows the guide rollers with tapered portions 16, 17 to maintain contact with the protruding line portion 83 and the adhesive tape application tool 1 stably moves along the protruding line portion 83. To ensure that.

In the adhesive tape application tool 1 of the present invention shown in Figs. 4, 5, and 6A, the guide roller having the tapered shape is provided so that the direction from the bottom to the top is sequentially downward, upward and downward. . The present invention is not limited to this embodiment. The adhesive tape application tool 1 of the present invention is an embodiment in which the protruding line portion is curved to the right (the direction shown by the protruding line portion 83 in Fig. 5). If the tool is designed to be curved in the opposite direction to the projecting line part, the guide roller having the tapered shape is installed so that the direction from the bottom part to the top part is in turn upward, downward and upward.

There is no restriction | limiting in the roller which has a tapered shape part of this invention. Any guide roller having a preferred mountain-type, ie, a shape in which the inclination of the horizontal cross-sectional area is reduced from the bottom to the top may be selected according to the bend shape made by the protruding line portion. Rollers with tapered shapes shown in side views in FIGS. 10A-10D may be presented by way of example. Fig. 10A shows a truncated conical guide roller having a tapered shape. 10B shows a guide roller having a tapered shape with a cylinder mounted on a truncated cone (same as the type shown in FIGS. 6A and 6B). The guide roller having the tapered shape shown in Fig. 10 (c) includes a cylinder mounted on a truncated cone similar to that shown in Fig. 10B. The protruding line portion projects from the bottom of the groove having the same axis with the concave groove-shaped rib in the form of a flange and the truncated cone is gradually inclined. The guide roller having the tapered shape shown in Fig. 10D includes a flange and a truncated cone having a gradual inclination in a manner similar to that shown in Fig. 10C. The inside of the flange, ie the bottom of the groove, is thin around the periphery, but thickens towards the point where the cylinder is mounted on the truncated cone, and the inside (axial side) of the cylinder has a uniform thickness.

The entire adhesive tape application tool of the present invention having the above characteristics is described with reference to the drawings.                 

Figures 2a to 2c show one embodiment of the adhesive tape application tool 1 according to the present invention, Figure 2a is a top view as seen from arrow Q of Figure 2b with the lever omitted, Figure 2b is a side view 2C is a front view as seen from arrow P of FIG. 2B.

The adhesive tape application tool 1 comprises a first support member 2 and a second support member 3. The first support member 2 includes a tape guide roller 13 for smoothly introducing the adhesive tape into the tool and discharging the peeling liner, and the adhered tape (eg, the door chassis frame 80 shown in FIG. 2B). ] The application part 5 including the pressure roller 15 which presses against the application surface. The tape guide roller 13 and the pressure roller 15 are mounted axially on the first support member 2. Of course, the pressure roller 15 should be mounted at least rotationally. The second support member 3 has a guide portion 6 including a guide roller having tapered portions 16 and 17, and the guide roller having tapered portions 16 and 17 has a second support. The member 3 is pushed down in the axial direction. The first support member 2 and the second support member 3 are contractively supported coaxially with the shaft 7. The coil spring 8 closing the first support member 2 and the second support member 3 is inserted into the shaft 7. The guide rollers having the pressure roller 15 of the application part 5 provided on the first support member 2 and the tapered shapes 16, 17 of the guide part 6 provided on the second support member 3 are Approach each other through the operation of the coil spring 8 to push down the door chassis frame 80 from both sides.

As can be seen from FIG. 2A, two tape guide rollers 13 are coaxially attached to both sides of the pressure roller 15 of the first support member 2. By using the tape guide roller 18, the adhesive tape is separated from the peeling liner 42 and guided to the pressing side 14 of the pressure roller 15, and the tape deflection is adjusted and bonded in the width direction. It is possible to send the tape 41 to the pressure roller 15. The adhesive tape 41 is sent along the surface of the pressure roller 15. When the transfer path of the adhesive tape 41 is reversed by the tape guide roller 13, the peeling liner 42 leaves the film and the adhesive layer 43 at the same time, and the film and the adhesive layer 43 are the pressure roller 15. Is pressed against the application surface of the door chassis frame 80 by the pressing side 14.

In addition, in the guide rollers having the tapered portions 16 and 17, the second support member 3 has an auxiliary roller in contact with the weather strip application portion 84 protruding from the rear surface of the door chassis frame 80. Preferably, 84 is provided. The contact of the auxiliary roller 27 with the weather strip application portion 84 of the door chassis frame 80 is such that the adhesive tape application tool 1 prevents the adhesive tape application tool 1 from swinging when the adhesive tape is applied. Is guaranteed to be attached to the door chassis frame 80, thereby improving the stability of the adhesive tape application tool 1.

The method of using the adhesive tape application tool of the present invention is described with reference to Figs. 2A to 2C. A conventionally known adhesive tape can be used as the adhesive tape 41.

First, the adhesive tape 41 passes through the opposite side surface of the door chassis frame 80 of the first tape guide roller 13 so that the peeling liner 42 does not face the pressure roller 15. The adhesive tape 41 then passes through the side opposite the press side 14 of the pressure roller 15 to reverse along the second tape guide roller 13. Thereafter, the adhesive tape 41 is sent to the press side 14 of the pressure roller 15. If the release liner 42 portion of the adhesive tape 41 is peeled off when the adhesive tape 41 reverses, the release liner 42 is removed from the adhesive layer 43 without going in the direction of the pressure roller 15. Can be removed (Figure 2A). The film and adhesive layer 43 are then sent to the pressing side 14 of the pressure roller 15, and the adhesive layer of the film and adhesive layer 43 is exposed on the application side of the door chassis frame 80.

In this state, the first supporting member 2 and the second supporting member 3 are opened by the operation of the lever 10. Thereafter, as shown in FIG. 2B, the first support member 2 and the second support member 3 contact the door chassis frame 80 with the protruding line portion 83 of the door chassis frame 80. The lever so that it can be pushed down from both sides by the guide roller and the pressure roller 15 having the retaining tapered portions 16 and 17 (only the guide rollers having the tapered portions 17 are shown in the drawing). It is closed by the operation of 10. In this way, the adhesive tape application tool 1 is set on the door chassis frame 80, and the film and adhesive layer 43 of the adhesive tape 41 are pressed against the pressing side 14 of the press roller 15. Is pressed against the application surface 81 of the door chassis frame 80.

When this condition is obtained, the adhesive tape application tool 1 moves along the door chassis frame 80 to move the adhesive tape 41. As the peeling liner 42 is separated from the adhesive tape 41, only the film and the adhesive layer 43 are applied to the application surface of the door chassis frame 80.

The adhesive tape application tool 1 of the present invention has a coaxially supported first support member 2 and a second support member 3 and a coil spring 8 operative to close the two support members 2, 3. And a lever 10 operative to open the two support members 2, 3 which withstand the coil spring 8. The first support member 2 and the second support member 3 are opened and closed by operating the lever 10 so that the adherend has a first support member 2 and a second support of the adhesive tape application tool 1. It can be rapidly depressed by the member 3.

In addition, by using the adhesive tape application tool 1 of the present invention, the adhesive tape 41 can be applied to the adherend by pressing the adhesive tape 41 to the adherend by a pressure roller 15 formed of an elastic material. have. Thus, the adhesive tape 41 is not easily damaged and does not generate bubbles remaining between the adherend and the adhesive tape.

In addition, in the adhesive tape application tool 1 of the present invention, the guide rollers at both ends are provided with the upper end oriented in one direction, and the other one of the centers has three tapered shapes provided with the upper end oriented in the other direction. Guide rollers 16 and 17 are provided. Thus, the projecting line portion of the adherend is not joined by one guide roller, but by a combination of three guide rollers 16, 17 having a tapered shape. This configuration prevents the adhesive tape application tool 1 from swinging in the vertical direction to ensure stable and smooth movement of the adhesive tape application tool 1 in the region formed by the straight line or the curved line portion.

Materials used to form the adhesive tape application tool of the present invention are described. The adhesive tape application tool is a fixture operated manually by a user to apply the adhesive tape. The purpose of this use is to require the adhesive tape application tool to be light enough to not suffer during long periods of use of the device. In addition, the tool should have sufficient strength to resist the stresses applied when applying the adhesive tape to the application surface. In addition, the applicator must have elasticity so that the adhesive tape remains fixed to the applicator surface. The material must maintain this elasticity for a long time. If these conditions are met, there are no material restrictions for the adhesive tape application tool. By way of example, the following materials can be used.

It is preferable that natural rubber and synthetic rubber, foamed plastic materials such as foamed polyurethane, various types of felt, and the like are used as the pressure rollers for the application portion. Parts other than the pressure roller can be made of polypropylene resin, polyethylene resin, polyacetal resin, ABS resin, nylon resin, acrylic resin, various types of fluorine-containing resin, aluminum and iron and other metals. In particular, hard-type or soft-type plastic materials are preferred as materials for the guide roller of the guide portion.
