Description

Tape Applicator

technical field

The present invention relates to a method and equipment for applying adhesive tape, in particular, to a tool for applying adhesive tape, and more particularly, to a method for applying adhesive tape on an object to be applied which has a protruding line portion on the opposite surface of the application surface. Tools used when applying tape.

Background technique

Sticking a film on the surface of an object can make the object have a good pattern or add function to the object. For example, colored films that mimic stained glass or opaque films for privacy can be pasted on transparent windows of houses, or UV protective films can be pasted on windows of vehicles to protect the skin of passengers and drivers. Since applying a film to an object protects the surface from air (oxygen), the application of a film instead of a coating is readily accepted.

It is well known in the art that neatly applying films to the surface of an object is difficult. One reason for this is the difficulty of properly positioning the film on the article. Another reason is the easy intrusion of air between the object and the film. After the film is applied, air can remain in the form of air bubbles resulting in an undesirable appearance. If the application work is not completed quickly, line marks (shocklines) may form in the area where the application work was suspended, which will impair its appearance. If there is an adhesive layer on the side of the film which is in contact with the object, the film must be positioned such that the adhesive cannot come into contact with the application surface in order to maintain the adhesion of the film to the object over a long period of time. This requirement adds to the difficulty of neatly and correctly applying the film to the object.

For example, some automobile component production lines have a step of applying a film (for example, a narrow width paint replacement film) to the surface of the car. More specifically, for example, on a door window frame 80 of a vehicle as shown in FIG. 9, a black adhesive tape (ie, a paint replacement film with an adhesive back) is applied to make the door window outline black to improve the vehicle's pattern. For example, a black adhesive tape includes a film layer (eg, made of polyvinyl chloride) as a base and an adhesive layer (eg, acrylic pressure-sensitive adhesive) disposed on the back of the film. In the past, window and door frames 80 have been painted with conventional coats of paint. However, the coating operation increases the environmental load due to the splashing of solvents and the generation of liquid waste, and requires a large number of process steps and relatively high operating costs. Adhesive-backed tapes with colored film layers (ie, paint-replacing films with an adhesive on the back) have become more popular in recent years for the reasons described above.

A seam will detract from the appearance of a vehicle when black tape is applied along the frame of a vehicle door or window. Therefore, if the door and window frame has a curved profile in a prominent location, it is best to apply a long strip of tape along the area that includes the curve. The curve here is, for example, the curve 91 of the vehicle door sash 80 shown in FIG. 9 .

However, when the tape is applied along a vehicle door sash, the application may not follow the curve of the door sash. Tape may deviate from the application surface, requiring the application operation to start over. Still another problem is that the tape application operation takes a long time because the tape cannot be correctly positioned on the curve in a short time. Since all of these problems reduce productivity and increase costs, there is a need for improved processes.

Tools for applying adhesive tapes have been proposed to improve these problems.

For example, Published Japanese Patent Application No. 123127/2001 proposes an adhesive tape application tool as shown in FIG. 3, which is capable of consistently and accurately applying adhesive tape at high speed. The tape application tool 101 applies the application tape with loosened paper to the door sash 80 while removing the loosened paper by moving the tool along the vehicle door sash 80 . The adhesive tape can be applied without trapping air bubbles because the tool is provided with elastic rollers 105 that press the adhesive tape against the adhesive tape application surface of the door and window frame 80 . In addition, guide rollers 106 having grooves 116 are formed behind the tape application surface of the door and window frame 80 . The guide roller 106 engages a protruding line portion 83 (convex) extending longitudinally along the door and window frame 80 so that highly accurate positioning can be ensured. The tool applies the tape precisely in this manner.

In recent years, however, many vehicle designers have favored small radius curves in window and door shapes or a curved shape with sharp corners rather than smooth curves. This undoubtedly requires that the protruding line portions 83 (convexities) extending longitudinally along the door and window frame 80 also form steep curves or sharp corners. In such a case, the guide roller 106 having the groove 116 may engage the line portion 83 (convexity) projecting on the curve of the door and window frame 80 due to the difference between the inner and outer rings. As a result, if the tape is applied on the elongated section, a deviation of the tape may occur on the curve; or, if the tool is moved slowly along the curve to avoid derailment of the guide roller 106 with the groove 116 from the protruding line portion 83 (convex), The tape may trap air bubbles causing thick lines.

Contents of the invention

The present invention has been made in consideration of the above circumstances, and an object thereof is to provide an adhesive tape applicator capable of applying adhesive tape to, for example, a door and window frame of a vehicle even if the curved shape of the door and window frame has a small radius or a steep curve with sharp corners , but also quickly without entrapment of air bubbles or misalignment of the tape application.

Considering that the tape application operation becomes difficult due to the change in the shape design of the vehicle door and window frame and the customer's strict requirements on the details of the appearance, it is strictly prohibited to have the seam of the tape in the obvious area. Extensively researched, this tool requires applying tape on an adhered object having a long and narrow application surface and a protruding line portion on the back side of the application surface. As a result, the present inventors achieved the object in the following way.

Specifically, the present invention provides a tool for applying an elongated adhesive tape to an adhered object having a long application surface and a protruding line portion formed longitudinally along the application surface at the back of the application surface. The adhesive tape applicator includes an applicator portion that is pressed against the application surface and a guide portion that includes three guide rollers (for example, mountain-shaped guide rollers) having tapered portions, and is in contact with the protruding line portion in such a manner that the The guide roller and the application part are clamped and the object to be pasted is clamped, wherein the guide part is provided with guide rollers, and the guide rollers with tapered parts at both ends point to the same direction during installation, while the guide rollers with tapered parts (middle) The other guide roller is mounted with its top pointing in the other direction.

In the present invention, the intermediate guide roller having the tapered portion is preferably installed so as to be rockable in the central axis direction. In other words, guide rollers with tapered portions are preferably mounted with tolerances. In addition, it is preferable that the application portion and the guide portion elastically clamp the adherend, and an opening and closing means for releasing the application portion and the guide portion from the adherend is provided.

Detailed ways

A preferred embodiment of the adhesive tape applicator tool (hereinafter sometimes simply referred to as "tool") of the present invention will now be described.

In the present invention, a guide roller having a tapered portion refers to a roller having a groove in which a ridge and a protruding line portion are formed in a shape protruding from the bottom surface of the groove provided coaxially with the groove, while the roller The protruding lines on one side have been removed.

The adhesive tape application tool of the present invention is a tool for quickly applying an elongated adhesive tape on an object to be adhered having a long application surface and a protruding line portion formed on the back side of the application surface along the longitudinal direction of the application surface, and It will not cause air bubbles to be trapped or deviate from the application position of the tape. The vehicle door sash 80 shown in FIG. 9 will be described as a specific example of the object to be pasted.

The door and window frame 80 generally has a cross-section as shown in FIG. 8 . The adhesive tape is applied to the application surface 81 visible from the outside instead of the coating. Weather stripping is attached to the back side 82 of the door and window frame 80 opposite the application surface 81 . On the back side 82 of the door and window frame 80, a protruding line portion 83 is formed as a raised ridge for fixing a weather strip. As shown in FIG. 9, the door frame 80 has a portion (curved portion 91) formed of a part of a straight line and a part of a curved line. Conventionally, it has been difficult to conveniently, quickly, aesthetically and correctly apply tape to the curved portion 91 of the application surface 81 . The present invention has solved this problem.

Fig. 1 is a perspective view showing an embodiment of the adhesive tape applicator of the present invention. Adhesive tape applicator tool 1 has applicator part 5 and guide part 6, and applicator part 5 comprises guide roller 13 and pinch roller 15, so that promote adhesive tape to stick to the application surface 81 of door frame 80 (for example shown in Fig. 8 and 9 ), and the guide portion 6 includes a guide roller with tapered portions 16 and 17, which is in contact with the protruding line portion 83 of the application surface 81 so that the application surface 81 and the application portion 5 are clamped together and along the protruding line Section 83 directs the movement of the tool. The guide part 6 is provided with guide rollers 17 located at both ends and having tapered portions, the tops of which point in the same direction in installation, and the guide part is also provided with intermediate guide rollers with tapered portions 16, the tops of which point in the other direction in installation. one direction. In addition, two auxiliary rollers 27 are provided for contacting the application portion in order to install the weather stripping of the door and window frame 80 and to grip the tape application tool 1 . As the tape applicator 1 moves along the protruding line portion 83, the auxiliary roller 27 rotates, thereby contributing to the stability of the tape applicator 1 while moving.

As shown in the tape applicator tool 1, the present invention is characterized in that guide rollers having tapered portions are installed at both ends, and other guide rollers having tapered portions are installed in opposite directions to each other. The guide rollers having tapered portions other than both ends are preferably installed swingably in the central axis direction.

This feature will now be described with reference to Figures 6(a), 6(b), 7(a) and 7(b) as compared to conventional tools. 6(a), 6(b) show the manner in which the guide rollers having the tapered portions 16, 17 come into contact with the protruding line portion 83 of the door and window frame 80 in the case of using the adhesive tape applicator 1 of the present invention. Tool parts other than guide rollers are omitted. Figure 6(a) is a view of the guide roller with the tapered portion 16 and the door and window frame 80 viewed from the direction facing the cross-section of the door and window frame 80, while Figure 6(b) is a similar view viewed from the direction facing the back side 82 of the door and window frame 80 . Also Figures 7(a), 7(b) show the manner in which the guide roller 106 with the groove 116 is in contact with the protruding line portion of the door and window frame 80 in the case of a conventional tool equipped with the guide roller 106 with the groove 116 . Tool parts other than guide rollers are omitted. FIG. 7( a ) is a view viewed from a direction facing the cross-sectional direction of the door and window frame 80 , and FIG. 7 ( b ) is a similar view viewed from a direction facing the back side 82 of the door and window frame 80 . In both cases of the tape applicator tool 1 of the present invention and the conventional tool, the guide rollers are elastically pressed in a direction (direction indicated by an arrow R in the figure) in contact with the protruding line portion by means not shown in the figure.

In a conventional tool, as can be understood from FIG. 7( a ), the groove 116 of the guide roller 106 engages the protruding line portion 83 of the door and window frame 80 so that the roller 106 can move along the protruding line portion 83 to guide the entire tool. Therefore, when the protruding line portion 83 is a straight line as shown in FIG. However, when the protruding line portion 83 is curved, the direction of the groove 116 of the guide roller 106 cannot be consistent with the direction of the protruding line portion 83 . The protruding line portion 83 cannot come into contact with the bottom of the groove 116 but floats, thereby hindering the stable operation of the guide roller 106 . When the protruding line portion 83 has a curve with a small radius, the guide roller 106 sometimes leaves the protruding line portion 83 .

This problem can be avoided with the inventive tool. In the adhesive tape applicator 1 of the present invention, a roller having a tapered portion forming a slope from the bottom to the top is used as a guide roller of the guide portion 6 to contact the protruding line portion 83 instead of a conventional guide roller having a groove. . In the tape applicator tool 1 of the present invention, a guide roller having a tapered portion does not engage the protruding line portion. Even if the roller with the tapered part is pressed to the direction shown by the arrow R in Fig. 6 (a), the guide roller only suppresses the downward deflection of the door and window frame, that is, for example, in Fig. 6 (a) the bottom of the roller with the tapered part Orientation, in other words, towards the opposite or deflection of the top of the guide roller with a tapered portion, such as the tool itself. The tool cannot move along the protruding line portion 83 in a stable manner with only one guide roller having a tapered portion.

As shown in FIG. 6( b ), the guide portion 6 is equipped with rollers having tapered portions 16 , 17 . The guide rollers with tapered portions 17 at both ends are mounted with their tops pointing in the same direction (downwards in the figure), while the middle guide rollers 16 with tapered portions are mounted with their tops pointing in the other direction (upwards in the figure) . Such a disposition shape guarantees that the undulation in the vertical direction (shown in FIG. 6 (b)) of the door and window frame 80 with the protruding line portion 83 and the adhesive tape applicator tool 1 with the tapered portion 16, 17 guide rollers is suppressed, which is By virtue of the presence of three guide rollers with tapered portions 16, 17 in the region of both the straight and curved protrusions, the tape applicator tool 1 is able to move smoothly and continuously along the protrusions.

It is inappropriate to provide only two guide rollers with tapered portions facing opposite to each other, because it is difficult to ensure the stability of linear running in such a configuration. On the other hand, for the case where the tool is equipped with rollers having four tapered portions, for example, when rollers having tapered portions are respectively provided at both ends and two guide rollers having tapered portions are installed in the middle thereof in opposite facing directions, Guide rollers with tapered sections cannot adequately run on curves and may run out of grooves as is the case with conventional tools, although the stability of straight running can be improved.

In the adhesive tape applicator 1 of the present invention, it is preferable that the roller having the tapered portion 16 is installed so as to be swingable with respect to the direction of the central axis, ie, the direction of arrow S shown in FIG. 6(b). In other words, the intermediate roller with the tapered portion 16 is preferably mounted with a certain tolerance. This configuration shape improves operability on curves. Even if the door and window frame is a curved shape with a small radius or a steep curve at a corner, the tape applicator 1 can move stably as the guide rollers having the tapered portions 16 , 17 keep in contact with the protruding line portion 83 .

For example, when utilizing the adhesive tape application tool 1 of the present invention to apply adhesive tape to the door and window frame 80, when the tool moves from the area where the protruding line part is a straight line as shown in Figure 4 to the area where the protruding line part 83 is a curve as shown in Figure 5 , the middle guide roller with a tapered portion moves upward along the middle axis (in the direction of S1 in the figure). This configuration shape ensures that the guide rollers with the tapered portions 16 , 17 remain in contact with the protruding line portion 83 and the tape applicator 1 moves along the protruding line portion 83 stably.

In the adhesive tape applicator 1 of the present invention shown in FIGS. 4, 5 and 6(b), guide rollers having tapered portions are installed so that the directions from the bottom to the top are sequentially downward, upward and downward. The present invention is not limited to this embodiment. The adhesive tape applicator 1 of this configuration is an embodiment that can allow the protruding line portion to bend rightward (the direction shown by the protruding line portion 83 in FIG. 5 ). If the tool needs to be designed to bend in opposite directions, the guide rollers with tapered sections should be mounted so that the sequence from bottom to top is upwards, downwards and upwards.

There is no limitation to the guide rollers having tapered portions in the present invention. Any guide roller with a preferred gable shape, ie a shape in which the slope of the horizontal section decreases from the bottom to the top, can be chosen following the curve drawn by the protruding line portion. A guide roller having a tapered portion in side view shown in Figs. 10(a)-10(d) can be taken as an example. Figure 10(a) shows an almost frusto-conical guide roller with a tapered portion. Figure 10(b) shows a guide roller with a tapered portion mounted on a frusto-conical cylinder (same shape shown in Figures 6(a), 6(b)). The guide roller shown in Figure 10(c) having a tapered portion comprises a shape similar to that of a cylinder mounted on a frustocone as described in Figure 10(b). The protruding line portion protrudes from the bottom of the groove having the same axis as the ridge-shaped concave groove, has a flange shape and is truncated to be gradually inclined. The guide roller having a tapered portion shown in FIG. 10(d) includes a flange and a frusto-cone having a gradual inclination in the same manner as shown in FIG. 10(b). The inside of the flange, ie the bottom of the groove, is thinner around the circumference, but thickens towards the axis until the intersection of the cylinder joining the frustocone, where the inside (axis side) of the cylinder has a uniform thickness.

The adhesive tape applicator tool of the present invention as a whole including the above features will be explained with reference to the accompanying drawings.

Fig. 2 (a)-2 (c) shows an embodiment of adhesive tape applicator tool 1 of the present invention, and wherein Fig. 2 (a) is the plan view viewed from arrow Q after omitting lever in Fig. 2 (b), Fig. 2 (b ) is a side view, and Fig. 2(c) is a front view viewed from arrow P in Fig. 2(b).

The tape applicator tool 1 mainly includes a first support 2 and a second support 3 . The first support 2 has an application portion 5, including tape guide rollers 13 for smoothly introducing the tape into the tool and discharging the layered liner, and for pressing the tape against the application surface of the object to be pasted (e.g. , The pinch roller 15 of door and window frame 80) shown in Fig. 2 (b). Tape guide rollers 13 and pressure rollers 15 are mounted axially on the first support 2 . In it, at least the pressure roller 15 must be rotatably mounted. The second support 3 has a guide portion comprising guide rollers with conical portions 16 , 17 which are axially clamped by the second support 3 . The first support 2 and the second support 3 are telescopically mounted coaxially with the shaft 7 . A coil spring 8 acting on the first support 2 and the second support 3 to bring them together is inserted on the shaft 7 . By the action of the coil spring 8, the pressure roller 15 of the application part 5 arranged on the first support part 2 and the guide roller with the conical part 16, 17 of the guide part 6 arranged on the second support part 3 Close to each other to clamp the door and window frame 80 from both sides.

As can be understood from FIG. 2( a ), two guide rollers 13 are fixed coaxially on both sides of the pressure roller 15 in the first support member 2 . Using the tape guide roller 13, not only can the tape 42 be separated from the layered liner 42 and guided to the pressure side 14 of the pinch roller, but also the deflection of the tape can be adjusted in the width direction and the tape can be stably delivered to the pinch roller 15. The adhesive tape 41 is conveyed along the surface of the pressure roller 15 . When the transmission path of the adhesive tape 41 was reversed by the adhesive tape guide roller 13, the layered liner 42 was separated from the film and the adhesive layer 43, and at the same time the film and the adhesive layer 43 were pressed against the door and window by the pressure side 14 of the pressing roller 15. frame 80 on the application surface.

In addition to the guide rollers having the tapered portions 16 , 19 , it is preferable that the second support member 3 is provided with an auxiliary roller 27 which is in contact with a weatherstrip application portion 84 protruding from the back side of the door and window frame 80 . The auxiliary roller 27 is in contact with the weather stripping application portion 84 protruding from the back of the door and window frame 80 to ensure that the tape applicator 1 is attached to the door and window frame 80, so that the tape applicator 1 can prevent swinging when applying the tape, thereby improving Stability of Tape Applicator Tool 1 .

A method of using the tape applicator of the present invention will be described with reference to FIGS. 2(a) to 2(c). A conventionally known adhesive tape can be used as the adhesive tape 41 .

First, the tape 41 passes the first tape guide roller 13 on the opposite side of the door and window frame 80 so that the layered liner 41 does not face the pinch roller 15 . Next, the tape 41 is passed through the side opposite the pressure side 14 of the pinch roller 15 so as to be reversed along the second tape guide roller 13 . The adhesive tape 41 is then fed to the pressure side 14 of the pressure roller 15 . If a portion of the layered liner of the tape 41 is peeled off when the tape 41 is reversed, the layered liner 42 can be removed from the adhesive layer 43 without going in the direction of the pinch roller 15 (FIG. 2(a)). Then, only the film and the adhesive layer 43 are sent to the pressure side 14 of the pressure roller 15 , while the adhesive layer of the film and the adhesive layer 43 become exposed on the application surface of the door and window frame 80 .

In this case, the first support 2 and the second support 3 are opened by the operation of the lever. Then, as shown in FIG. 2( b), the first support member 2 and the second support member 3 are closed by the operation of the lever 10, so that the door and window frame 80 can be driven by the guide rollers and the pressure rollers with the tapered portions 16,17. 15 is clamped from both sides, while the guide rollers with tapered portions 16 , 17 (only the guide roller with tapered portion 17 is shown in the figure) remain in contact with the protruding line portion 83 of the door and window frame 80 . In such a manner, the adhesive tape application tool 1 is arranged on the door and window frame 80, and the film of the adhesive tape 41 and the adhesive layer 43 are pressed against the application surface of the door and window frame 80 by the pressure side 14 of the pressure roller 15 .

When such a state is reached, the adhesive tape applicator 1 is urged to move along the door and window frame 80, thereby causing the adhesive tape 41 to move. Only the film and adhesive layer 43 are applied on the application surface of the door and window frame 80 , while the layered liner is separated from the adhesive tape 41 .

The first support 2 and the second support 3 coaxially supported by the adhesive tape application tool 1 of the present invention, the coil spring 8 acts to close the two supports 2, 3, and the lever 10 acts to resist the coil spring 8 and open two supports 2,3. The first and second support members 2 , 3 are opened and closed by the lever 10 , so that the object to be pasted can be quickly clamped by the two support members 2 , 3 of the tape applicator tool 1 .

In addition, with the adhesive tape applying tool 1 of the present invention, it is possible to apply the adhesive tape 41 to the adhered object by pressing the adhesive tape with the pinch roller 15 made of elastic material against the adhered object. Thus, the adhesive tape 41 is not easily damaged, and no air bubbles remain between the object to be adhered and the adhesive tape.

Furthermore, the tape applicator tool 1 of the present invention is provided with three guide rollers with tapered portions 16, 17, wherein the rollers mounted at both ends have their tops pointing in one direction and the other middle roller is mounted with their tops pointing in the other direction. Thus, the protruding line portion of the object being pasted is not engaged by just one roller, but by a set of three guide rollers with tapered portions 16,17. Such a disposition shape prevents the tape applicator 1 from swinging in the vertical direction, and ensures smooth movement of the tape applicator 1 in the region where the protruding line portion is shaped as a straight line and a curve.

Hereinafter, the materials used to form the tape applicator tool 1 of the present invention will be discussed. The tape applicator tool is a working jig that is manually operated by a user to apply tape. This purpose of use requires that the tape applicator should be lightweight to such an extent that the device cannot cause pain in prolonged use. Also, the tool must be strong enough to resist the stresses that occur when the tape is applied to the surface of the object. In addition, the application portion must be elastic so that the tape adheres securely to the application surface. The material must maintain such elasticity over a long period of time. There are no restrictions on the materials used for the tape applicator as long as these conditions are met. For example, the following materials can be used.

Rubber materials such as natural rubber and synthetic rubber, foam plastic materials such as foamed urethane, and various types of felt are preferably applied to the pinch roller of the application portion. Parts other than the pinch roller can be made of metals such as polypropylene resin, polyethylene resin, metaldehyde resin, ABS resin, nylon resin, acrylic resin, various types of fluorine-containing resins, aluminum, iron, and alloys of these metals. become. In particular, hard and soft plastic materials are preferred materials for the guide rollers of the guide section.

It can be understood from the above description that the tape application tool can quickly apply tape on the object to be pasted, even if the surface of the object to be pasted is curved or the surface curve is steep with sharp corners, and it will not contain air bubbles or cause the tape to be applied. Deviate. While the above disclosure specifically refers to the application of the invention to automobile-type vehicles, it should be understood that the invention may also be applied to other types of vehicles (eg, aircraft, watercraft, etc.) and other objects to be bonded.
