More specifically, the present invention can be advantageously used, for example, when attaching an adhesive tape to a center pillar portion of an automobile.

[0002]

2. Description of the Related Art Conventionally, when an adhesive tape is applied to an adherend, it is manually performed. For example, an operator presses and sticks one end of an adhesive tape to an adherend while visually confirming the tape sticking position of the adherend, and sets a sticking start position. After the application of the adhesive tape at the application start position is completed, the continuation of the adhesive tape is little by little, while following the curved portion of the application surface and making light contact with the adherend, wrinkles do not change. As described above, the squeegee or a roller is used to manually press and adhere to the adherend while paying attention not to cause air biting. If the adhesive tape cannot be applied to the desired tape application position, the adhesive tape that has been applied must be peeled off from the adherend, and the tape application operation must be repeated again after correcting the tape application position. No. Further, when such a re-sticking operation is repeated, the adhesive sheet itself often suffers damage, and the adhesive operation must be repeated from the beginning using a new adhesive tape. As described above, in the conventional method, the work of applying the tape requires labor, time, and importantly, skill, and attention must be paid to the generation of wrinkles and air bites.

[0003] The disadvantages of the conventional methods as described above are, in particular,
This is remarkable when the adherend is a long object, when the surface to be adhered is curved, and when the adhesive tape to be used is a long object. That is, in such a case,
The above-mentioned complicated and problematic steps must be repeated, and the problem that wrinkles are likely to occur and air easily enters more frequently, while avoiding the problem depends on the skill of the operator. However, it is large, and the working time is prolonged in proportion to the length of the long object. Further, naturally, since the operation of peeling off the adhesive tape attached to the adherend and reattaching it is repeated, defects such as damage to the adhesive tape itself occur more frequently.

[0004]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An adhesive tape to be supported by a supporting method and a supporting jig according to the present invention has a substrate and a pressure-sensitive adhesive layer coated on at least one surface thereof. Can be configured similarly to a conventional adhesive tape. The adhesive tape according to the present invention is preferably
An adhesive tape comprising a substrate and an adhesive layer applied to one surface thereof. The pressure-sensitive adhesive tape preferably has a sticking area corresponding to the sticking surface of the adherend and occupying an area corresponding thereto, and is located adjacent to one side of the sticking area. A tape positioning / fixing area provided with a receiving portion capable of receiving a tape positioning / fixing member provided in the vicinity of a start position of tape adhering to the body; and a tape positioning / fixing area positioned adjacent to another side of the adhering area. So,
And a tape guide area provided with a receiving portion capable of receiving a tape guide member provided in the vicinity of the end position of tape application to the adherend.

The pressure-sensitive adhesive tape used in the present invention comprises:
Preferably provided in the form of a rectangular tape or film,
Also, the width may be relatively narrow (eg, about 2
３3 cm), or conversely, wider (eg, about 10 cm or more). But in general,
It is preferable that the width of the adhesive tape is large enough to allow the sticking operation to be performed manually. The length of the pressure-sensitive adhesive tape is also arbitrary, as is the case with the tape width. However, in order to fully exert the effects of the present invention, the tape may be long, and the effects of the present invention can be more exerted. The preferred length of the adhesive tape is usually in the range of about 20 to 100 cm.

As described above, in order to adapt the adhesive tape to the tape supporting method and the tape supporting jig of the present invention,
At least the following three areas are preferably classified into (1) an attaching area, (2) a tape positioning / fixing area, and (3) a tape guiding area.

The first region is a sticking region corresponding to the surface to be stuck of the adherend and occupying an area corresponding thereto. This region is a portion that performs the essential function of the adhesive tape, and therefore may have basically the same configuration, shape, dimensions, and the like as the conventional adhesive tape. The second area is a tape positioning / fixing area for positioning the pressure-sensitive adhesive tape, particularly for specifying the position at which the tape is to be pasted. This region is located adjacent to one side of the above-mentioned attaching region, and receives a tape positioning / fixing member provided near a start position of attaching the tape to the adherend at a predetermined portion thereof. It has a possible receiving part. The tape positioning / fixing area is used when the adherend extends vertically, for example, in the center pillar of an automobile.
When the pressure-sensitive adhesive tape is applied to the adherend, the pressure-sensitive adhesive tape is pressed and adhered while sequentially pressing the pressure tape from the upper side to the lower side. Further, it is desirable that the shape of the tape positioning / fixing area is as simple as possible. Generally, the tape positioning / fixing area is formed to have the same width as the extension of the adhesive tape attaching area. Therefore, it is preferable that the area be as small as possible.

In the tape positioning / fixing area, it is necessary to provide a receiving portion capable of receiving the tape positioning / fixing member at a predetermined position. Here, the tape positioning / fixing member is to be attached to a tape positioning guide (described below) which is one member of the tape support jig of the present invention, and preferably, the tape positioning / fixing member is preferably a tape positioning / fixing member. Can be in the form of a pin. Tape alignment pins or other forms of tape positioning / fixing members can be attached to any one or more of the tape alignment guides at any given location,
To accurately position the adhesive tape and stably support it,
It is preferable to attach two or three pieces in combination.

[0012] In the tape positioning / fixing area, the receiving portion that can receive the tape positioning / fixing member can be arbitrarily changed according to the shape and number of the tape positioning / fixing members to be used. For example, when the tape positioning / fixing member is composed of two pins, the receiving portion of the tape positioning / fixing region is also formed into two perfect circular openings having substantially the same diameter as the pins. The arrangement of the holes can also be adjusted to the arrangement of the two pins.

The third area is a tape guide area for guiding an adhesive tape, and particularly for specifying a sticking end position at the time of sticking the tape. This area is located adjacent to one side of the above-mentioned attaching area (the side other than where the tape positioning / fixing area is in contact), and at a predetermined position, the end position of the tape attaching to the adherend A receiving portion capable of receiving a tape guide member provided in the vicinity is provided.

The tape guiding area is usually one of the adhesive tapes.
The same length on one side or else
It is preferable to provide the same width on the extension of the sticking area below the adhesive tape (that is, on the side opposite to the above-described tape positioning / fixing area). This area is also preferably as small as possible in terms of manufacturing cost and the like.

In the tape guide area, at a predetermined portion thereof,
It is necessary to provide a receiving part capable of receiving the tape guide member. Here, the tape guide member is to be attached to a tape guide guide (described below), which is one member of the tape support jig of the present invention, and is preferably a tape guide rod. Can be One or more arbitrary number of tape guide rods or other types of tape guide members can be attached to a predetermined portion of the tape guide guide. However, only one piece is attached in terms of operability and the like. Is preferred.

In the tape guiding area, the receiving portion capable of receiving the tape guiding member can be arbitrarily changed according to the shape and the number of the tape guiding members to be used. For example, when the tape guide member is formed of one rod, the receiving portion of the tape guide region is also formed into one elliptical (or slit-shaped) opening having substantially the same width as the rod. be able to. It is, of course, necessary for the receiving portion to be designed in a shape and a size such that when performing the operation of supporting and guiding the adhesive tape, the tape guiding member does not cause any inconvenience such as adversely affecting the operation. .

In the pressure-sensitive adhesive tape used in the present invention, the pressure-sensitive adhesive layer has one of the three regions described above.
It may be selectively applied only to the attaching area, or may be applied to the entire area of the attaching area, the tape positioning / fixing area, and the tape guiding area when preferable from the viewpoint of the manufacturing process. . In the latter case, in order to avoid undesired sticking of the adhesive tape to the adherend, a "cut" is made in advance at the boundary of each area, or the adhesive layer of the tape positioning / fixing area and the tape guiding area is removed. It is preferable to cover with release paper or the like.

When the above-mentioned and other adhesive tapes are applied to the surface to be adhered of the adherend, there are the following two steps: (1) tape positioning / fixing step, and (2) tape guiding step, It can be used advantageously by supporting the adhesive tape with.

In the tape positioning / fixing step, the tape positioning / fixing member (for example, a pin-like member) of the tape positioning guide fixedly attached near the starting position of sticking to the adherend is attached to the tape of the adhesive tape. This is a step of preliminarily adjusting the pressure-sensitive adhesive tape to the sticking start position of the adherend by receiving it in a receiving portion (for example, a perfect circular opening or the like) of the positioning / fixing region. The tape positioning / fixing member and the receiving portion of the tape positioning / fixing region are paired as described above, and are preferably used in two pairs as described above. When this step is completed, the pressure-sensitive adhesive tape can be accurately positioned and stably fixed at the sticking start position of the adherend.

In the tape guiding step, the tape guiding member (for example, a rod-shaped member) of the tape guiding guide fixedly attached to the vicinity of the end position of the tape application to the adherend is received in the tape guiding area of the adhesive tape. This is a step of preliminarily adjusting the adhesive tape to the sticking end position of the adherend by receiving the adhesive tape in a portion (for example, an oval opening). The tape guide member and the receiving portion of the tape guide region are paired as described above, and are preferably used in a pair as described above. When this process is completed, the end of the adhesive tape is accurately positioned near the end of the adhesive tape at the end of application of the adherend. It is possible to perform an appropriate attaching work while preventing the inconvenience of the above.

In the method of the present invention, the pressure-sensitive adhesive tape is pressure-bonded to the adherend by such two steps under the condition that the pressure-sensitive adhesive tape is adapted to each of the sticking start position and the sticking end position of the adherend. be able to. In addition, pressure bonding and sticking of the adhesive tape can be performed according to a conventional method, and in that case,
In order to more effectively perform pressure bonding of the adhesive tape, it is preferable to use pressure bonding auxiliary means such as a squeegee or a roller. For example, the squeegee sequentially presses the adhesive tape against the tape application site of the adherend, preferably presses it while gradually increasing the pressing force, and finally applies the adhesive tape in close contact with the tape application site. It is preferable to use a hard plastic material or the like in consideration of handleability and strength, and it is preferable that the surface portion is made of an elastic material. Suitable elastic materials include, for example, natural and synthetic rubbers, foamed plastic materials, such as foamed polyurethane, various felt materials, and the like.

In the practice of the method of the present invention, when release paper or the like is laminated on the surface of the pressure-sensitive adhesive layer of the pressure-sensitive adhesive tape, it may be changed depending on the lamination form of the release paper or the like. Usually, the release paper or the like can be peeled and removed at any timing between the tape positioning / fixing step and the tape guiding step, or after the tape guiding step and before the actual tape attaching operation is started. is necessary.

[0023] In addition to the above-described adhesive tape supporting method, the above-mentioned and other adhesive tapes are used for attaching the above-mentioned adhesive tape to an adherend surface of an adherend in the following two guide members: (1) Advantageously using an adhesive tape with an adhesive tape support jig having a combination of a tape alignment guide for positioning / fixing the tape, and (2) a tape guide guide for guiding the tape.

Can be fixedly held.

The tape guiding area C is used to specify the position where the tape is to be pasted, particularly when the tape is pasted. As shown in the drawing, the tape guiding area C extends on the lateral side of the pasting area A. The tape guide area C has one oval rod receiving opening 6 as shown in the figure. The opening 6 is provided with an adhesive tape 10
When the is adhered to the adherend, the tape guide rod of the tape guide guide is received, so that the adhesive tape 10 can be held at the end position of the adherend on the adherend. Since the shape of the opening 6 is elliptical, even when the adhesive tape 10 gradually approaches the adherend as the tape attaching operation proceeds,
Appropriate movement of the adhesive tape 10 can be guaranteed.

FIG. 2 is a perspective view showing an example in which an adhesive tape supporting jig according to a preferred embodiment of the present invention is mounted on an adherend. The configuration of the illustrated adhesive tape bearing jig will be more apparent from FIG. 3 which is a perspective view of the tape alignment guide, and FIG. 4 which is a perspective view of the tape guide. The adherend 20 has a vertically long cubic shape, and one surface thereof is the adherend surface D. As can be understood from the state of attachment of the tape positioning guide 30 and the tape guide guide 40 in FIG.
The fixing portion 32 (see FIG. 3) of the tape guide guide 40 is fitted into the lower concave portion in the adherend 20.

Further, as can be understood from a perspective view enlarged in FIG. 3, the tape positioning guide 30 is composed of a frame body 31 and a fixing portion 32, and is attached when the frame body 31 is attached to the adherend 20. Two tape positioning pins 35 are attached to the same surface as the sticking surface D. Further, as can be understood from the perspective view enlarged in FIG. 4, the tape guide 40 is composed of a frame body 41 and a fixing portion 42, and is attached to the frame body 41 when attached to the adherend 20. On the same surface as the mounting surface D, one tape guiding rod 46 is provided.
Is attached. The tape positioning guide 30 and the tape guide 40 are both made of polyacetal resin.

When the tape support jig of the present invention described with reference to FIGS. 2 to 4 is used, the adhesive tape of FIG. 1 can be supported and adhered to an adherend as follows. First, as shown in FIG. 5, two tape positioning pins 35 of the tape positioning guide 30 attached to the adherend 20 are inserted into two pin receiving apertures opened at the upper end of the adhesive tape 10. Insert into 5. Since the diameter of the pin 35 and the diameter of the opening 5 are almost the same size, the adhesive tape 10 can be adapted to the sticking start position of the adherend 20, and the tape is careless during the subsequent tape sticking operation. Does not move. Adhesive tape 1 for attachment start position of adherend 20
After the completion of the adaptation of No. 0, the release paper 3 covering the adhesive layer of the adhesive tape 10 is peeled off and removed.

Subsequently, as shown in FIG.
One tape guide rod 46 of the tape guide guide 40 attached to the tape insertion guide 0 is inserted into one rod receiving opening 6 opened at the lower end of the adhesive tape 10. Here, opening 6
Is oval, so that even when the rod 46 is inserted therein, the pin 35 can be fixedly held, as opposed to the pin receiving opening 5 described above, with an appropriate play. An adhesive tape 10 can be supported. As a result of this play, according to the present invention, the adhesive tape 10 can be adapted to the position where the adherend 20 has been pasted.

The squeegee 15 is used to effectively perform the tape pressing, and the adhesive tape 10 is adhered to the adherend 20 by tracing the surface of the vertically extending adhesive tape 10 from top to bottom in the direction of the arrow. The tape is attached while crimping. The adhesive tape 10 can be quickly and neatly stuck to the adherend 20 without inconveniences such as air biting and wrinkling by a single tape pressing / adhering operation.

FIG. 8 is a perspective view showing another example of an adhesive tape which is advantageously used in the practice of the present invention. As understood from the figure, this adhesive tape 10
The structure differs from the adhesive tape 10 of FIG. 1 in that the tape guide area C is moved to the opposite side of the tape positioning / fixing area B. Further, with the change in the structure of the adhesive tape 10, the adhesive tape support jig was also changed as shown in FIG. That is, the adhesive tape supporting jig 50 includes a tape positioning guide 51 provided with a tape positioning pin 55, a tape guide 52 provided with a tape guiding rod 56, a tape positioning guide 51 and a tape guide 52. And a stay 53 connecting the two.
Since the stay 53 has a length adjusting means 54 including a screw (not shown) in the middle thereof, it is possible to arbitrarily adjust the interval between the guides 51 and 52 according to the length of the adherend. Can be.

The adhesive tape supporting jig 50 shown in FIG.
When the pressure-sensitive adhesive tape 10 of FIG. 8 is attached to the curved adherend surface D of the adherend 20 shown in FIG. 11, after attaching to the adherend 20 as shown in FIG. 7, the pressure-sensitive adhesive tape 10 can be attached to the adherend 20 while being pressed against the adherend 20 in the same manner as described in order with reference to FIG. Although there is a situation where the adhered surface D of the adherend 20 is curved and the adhesive tape 10 is difficult to adhere,
The adhesive tape 10 can be quickly and neatly stuck without inconveniences such as air biting and wrinkling.

[0040]

As is apparent from the above description, when the tape supporting method and the supporting jig of the pressure-sensitive adhesive tape according to the present invention are used, the tape is long or the surface to be adhered is curved. When sticking a long adhesive tape to such an adherend, the tape can be positioned stably and accurately, and defects such as wrinkles and air bites are unlikely to occur, which may cause damage to the adhesive tape. In addition, even a worker who is not skilled in technology can easily and easily perform the sticking operation. In particular, according to the present invention, after applying an adhesive tape to an adherend using the tape support jig of the present invention, appropriate tape crimping means is applied from the start position to the end position of tape application to the adherend. Even if the adherend is long and it is curved, it can be easily adhered without wrinkles or air bites regardless of the skill level of the worker, by a single operation of just sliding The operation of attaching the tape can be completed.
