[0002]

2. Description of the Related Art Conventionally, when an adhesive tape is adhered to an adherend such as a sash frame of an automobile, the adhesive tape is usually applied to the tape adhered surface of the adherend, and the adhesive tape is further applied to the adherend. I'm going to get involved. That is, FIG.
After the adhesive surface 6a of the adhesive tape 6 is applied to the tape-attached surface of the adherend 5 as shown in step (A), the end surface of the adhesive tape 6 is made as shown in step (B) of FIG. Bend the
It is wound around the adherend 5. Furthermore, the wound adhesive tape 6 is
As shown in the step (C) of FIG. 1, it is carefully attached to the adherend 5 using a squeegee or the like (not shown). However, such a wrapping and sticking operation, especially when sticking an adhesive tape to a curved surface portion of an adherend, easily causes wrinkles and air bites, and the skill of the worker is important,
There is also a problem that the working time is long.

Conventionally, a sticking jig has been used instead of a squeegee or the like. For example, JP-A-9-13
Japanese Patent No. 2218 discloses a jig capable of freely and easily completing the operation of folding and sticking an adhesive tape irrespective of the shape of the adherend. A jig for folding and sticking an adhesive tape, comprising a guide forming means movable along the upper surface, is disclosed. The guide forming means of the attaching jig has a function of sequentially pressing the adhesive tape against the adherend and finally bringing the adhesive tape into close contact. However, such jigs also have problems. That is, since the positional relationship between the adhesive tape affixing portion of the adherend and the jig changes slightly each time, it is indispensable to use a highly elastic material for the guide forming means. Poor tape application often occurs.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to improve the skill of an operator when applying an adhesive tape to an adherend, particularly a long adherend having a curved portion in the middle thereof. An object of the present invention is to provide an adhesive tape sticking jig that can quickly and stably and reliably wrap an adhesive tape and perform sticking work without causing poor sticking due to insufficient bonding force. .

Another object of the present invention is to provide a jig for sticking an adhesive tape, which is small, lightweight, compact, and excellent in handleability.

[0006]

The inventor of the present invention has conducted intensive studies in order to solve the above-mentioned problems, and as a result, the function of the attaching jig has been divided into several members, and at the same time,
The inventors have found that it is effective to correlate the functions of those members, and have completed the present invention.

Accordingly, the present invention is to move and use the adhesive tape on the adherend so as to wind and adhere the adhesive tape to the adherend. A row of adhesive tape winding members attached to the jig body, each of which is slidable on the adherend with at least a portion of the adherend interposed therebetween. It consists of a pair of guide rollers, and the pair of guide rollers are independent of each other, and each have a different shape and function, and the adhesive tape is sequentially wound around the tape-attached surface of the adherend. A jig for winding and sticking an adhesive tape, wherein the jig is attached to the jig main body at a position where the jig is pressed and attached.

[0008] In short, the present invention moves the adhesive tape of the present invention on an adherend by sequentially moving the adhesive tape by a plurality of adhesive tape winding members constituting the jig. It is characterized in that winding is performed. Since each of the adhesive tape winding members is formed in an optimum shape from a material most suitable for the target adherend, and preferably, a positioning mechanism is also provided on the jig itself, so that the adherend The adhesive tape is gradually folded in accordance with the shape of the tape, and can be accurately and easily attached without generating air bites or wrinkles.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A jig for winding and sticking an adhesive tape according to the present invention comprises a jig main body and a plurality of adhesive tape winding members. The adhesive tape winding members are attached to the jig main body in a row and in association with each other so that the adherend can pass between the respective members. By forming the jig from a row of the adhesive tape winding members and associating the jigs with each other, the jig can be compactly and lightweight, and the handleability and the like can be improved. As used herein, the term "associate with each other" means that, as can be understood from the following detailed description, it is obvious that the adhesive tape wrapping members show the expected operation, It means that the function of the jig can be assured as a whole in cooperation with the adhesive tape winding member arranged in the above manner. Specifically, for example, assuming that the adherend is sent from one winding member, the receiving winding member inherits or makes use of the function of the preceding winding member while retaining its own function. Then, the adherend can be transferred to the next winding member. In addition, it will be described here that in the practice of the present invention, the shape of the adherend to which the winding and attaching jig of the present invention is used is not particularly limited. An adherend that can exhibit all the effects is long and has a bent portion, a curved portion, a corner portion, or the like (hereinafter, collectively referred to as a “bent portion”) having an angle in the middle thereof.

In the winding and attaching jig of the present invention, each of the adhesive tape winding members is composed of a pair of guide rollers slidable on the adherend with at least a part of the adherend interposed therebetween. That is, when the jig is moved on the adherend at the time of applying the adhesive tape, the guide roller constituting the jig can run while being mounted on the adherend in a state of riding or similar. It is. The running of the jig is not delayed or interrupted.

Further, the winding and attaching jig of the present invention employs a configuration in which a pair of guide rollers are arranged in series. The number of pairs of guide rollers that make up the jig depends on the shape and size of the adherend, but if the jig is downsized,
Usually, it is preferable that the jig is composed of 3 to 5 pairs of guide rollers, and it is more preferable that the jig is composed of 3 to 4 pairs of guide rollers.

Furthermore, each pair of guide rollers is
From independent and identical or different materials,
Molded to have different shapes and functions. By adopting such a configuration unique to the present invention,
As described above, when the adherend passes between the opposing guide rollers, the adhesive tape can be sequentially wound around the tape-applied surface of the adherend, and can be adhered by pressing. Therefore, each pair of guide rollers needs to be attached to the jig body at a position where the adhesive tape can be stuck in such a form. The guide roller, that is, the adhesive winding member may be directly attached to the jig main body, or may be attached via an appropriate intermediate member (such as a base).

[0013] The winding and attaching jig of the present invention, even when the row of adhesive winding members is composed of a plurality of pairs of guide rollers as described above, has a higher bonding reliability than a conventional adhesive tape attaching jig. At the end of the row of the adhesive tape wrapping member, one guide roller and a jig fixing mechanism arranged opposite to the guide roller can be obtained, although excellent action and effect can be obtained in terms of operability and handleability. It is preferable to further provide an adhesive tape winding member including an adherend guide attached. The guide roller and the adherend guide not only allow the jig to move smoothly on the adherend while sandwiching the adherend, but also provide a jig fixing mechanism for the adherend guide, usually a guide groove. The tool can be positioned on the adherend and fixed so as not to swing. It is a matter of course that the final adhesive tape winding member can more reliably adhere and press the adhesive tape to the adherend.

As described above, the jig for winding and sticking the adhesive tape of the present invention usually employs a structure in which the adhesive tape winding member is disposed only on the side surface of the adherend. However, in order to further enhance the effect of the jig, at least one of the adhesive tape wrapping members may further include an additional guide roller that moves while being in contact with the adherend on the surface on which the tape is adhered. preferable. By the presence of such additional guide rollers, the jig can run more smoothly on the adherend, workability can be improved, and time can be reduced.

More specifically, in the jig for winding and sticking the adhesive tape according to the present invention, the adhesive tape winding member is arranged such that, when viewed from the entry side of the adherend with respect to the jig,
It may include a pair of first guide rollers, a pair of second guide rollers, a pair of third guide rollers, and a pair of a fourth guide roller and an adherend guide with an adherend fixing mechanism. preferable.

Here, the adhesive tape winding member can have various variations within the scope of the present invention, but the first guide roller (pair) is rotatably mounted on the jig body. It is preferable to be able to swing in accordance with the shape and movement of the adherend while supporting the bottom (tape application surface) of the adherend.
This is because the positioning and setting of the jig at the tip of the adherend as the first stage of the operation can be performed efficiently and accurately.

After the tip of the adherend is set on the first guide roller, it moves to the second guide roller (pair). Each of these guide rollers can move while being in contact with the side surface of the adherend passing between them by the attached urging means. Further, the third guide roller (pair) can move while pressing the adherend passing therethrough against the jig by the attached urging means.

Further, the fourth guide roller moves while being in contact with the side surface of the adherend, and the adherend guide combined with the guide roller is moved by the jig fixing mechanism. Swing at the time can be suppressed. In the winding sticking jig of the present invention, in addition, in order to improve the setting work for the adherend of the jig,
Preferably, some improvements have been made.

First, the above-described fourth guide roller and the second and third guide rollers (one of a pair) located on the same side as the guide roller are used when the jig is set. It is preferable to be able to move to a position away from the guide and the other guide roller. Since the gap between the guide rollers and the gap between the guide roller and the adherend guide are widened, not only is it easy to set the jig on the adherend, but also when the gap is closed again, the adherend is moved to the guide roller or the adherend. This is because the body can be stably and slidably fixed by the wearing body guide.

Although such a movable jig fixing mechanism can employ various configurations, the second, third and fourth guide rollers can be jointly mounted on a common base, for example, a movable block. It is preferable to mount the base and move the base simultaneously. The movement of the movable block is advantageously provided with a sliding member. Although the slide member can have various forms, usually, the movable block is moved in the horizontal direction on the slide member so that the interval (positional relationship) between the guide rollers can be arbitrarily adjusted. , A pole shape, a rail shape, or the like. That is, it is preferable to mount the slide member at an appropriate position on the movable block in combination.

In the movable block, an urging means is advantageously used in combination with the above-mentioned slide member. This is because the movable block can be locked and released more efficiently by the spring force of the urging means. That is, when a guide roller or the like supported by the movable block overcomes the spring force and reaches a predetermined position on the side surface of the adherend, the stop mechanism operates to lock the movable block and set the jig. Can be. When this lock is released, the spring returns to the state before setting. In addition, if the jig body has an urging member, a predetermined portion of the jig can be brought into contact with the adherend with an appropriate pressing force when the winding and attaching jig is used. It can be attached to the body with an increased pressure. The urging member used here is not particularly limited as long as the member can perform an intended function, but is preferably an elastic member such as a spring or a spring. In order to reduce the size of the jig, it is preferable that these urging members are attached, for example, so as to surround the slide member.

Further, a combination of a push lever and an index plunger can be advantageously used for moving, locking and releasing the movable block as described above. That is, an open state is obtained by pulling the index plunger, and the jig can be set on the adherend. Then, when the push lever is pushed in, the open state is released and the closed (locked) state is obtained. This is because the tip of the index plunger fits into the hole formed in the movable block. When it is desired to obtain the open state again, the lock can be released by pulling the index plunger.

Secondly, it is preferable that a biasing means is attached to the adherend guide so that the adherend guide can be moved up and down by its spring force. In addition, in order to easily move the adherend guide up and down, it is preferable to use a gripper such as a set lever together. The set lever is pinched by hand, and the adherend is moved while the space below the set lever (at least a part of the adherend is guided here) is widened. After positioning the jig with the adherend fixing mechanism attached to the adherend guide, preferably the guide groove, release the set lever. The corresponding protrusion of the adherend fits into the guide groove of the adherend guide, and the jig is fixed by the spring force.

The urging means and the gripper of the adherend guide will be further described. The urging member used here is not particularly limited as long as the urging member can perform the intended function, similarly to the urging member described above, but is preferably a stretchable member such as a spring or a spring. It is. In order to reduce the size of the jig, for example, it is preferable that these urging members are attached, for example, by incorporating a main portion thereof into an adherend guide and, if necessary, a fine hole opened in the jig body. If the adherend guide has an urging member, a space can be provided below the adherend guide by contracting the urging member, so that the winding and attaching jig is attached to a predetermined portion of the adherend. Work can be performed easily and accurately. In addition, when the urging member is in the original open state, when the jig is used, a predetermined portion of the jig can be brought into contact with the adherend with an appropriate pressing force, and the adhesive tape is adhered to the adherend. Can be applied with an increased pressure. In addition, as described above, the urging member is fitted with the protrusion of the adherend in the groove of the adherend guide to assist the operation of securely fixing the jig to the adherend. There is also work.

The winding and attaching jig of the present invention preferably includes a gripper in addition to the urging member, preferably in combination with the urging member. This is because the holding tool can easily perform the operation of attaching the adhesive tape and the expansion and contraction of the urging member. It is preferable that the gripping tool is usually composed of a pair of plate-shaped plastic members, one of which is attached to the jig body and used, but may be configured in another form as needed.

The members constituting the winding and attaching jig of the present invention will be described in more detail. The jig body is usually in the form of a plate in order to make the final product small, lightweight and compact, and to make it easy to handle, on which various components are placed and mounted. ,
It is preferable to form a box without a lid and store and attach various constituent members inside the box. Further, such a jig main body can be formed from various materials. Materials suitable for forming the jig body are metal materials such as iron, aluminum or alloys thereof, plastic materials such as polypropylene resin, polyethylene resin, polyacetal resin, ABS resin, nylon resin, fluorine-containing resin, acrylic resin, and the like. Others. Among such materials, a particularly suitable material is a lightweight plastic material that does not bear its weight even when working for a long time.

It is preferable that the adhesive tape winding member attached to the jig body is constituted by a guide roller as described above. Further, such a guide roller may be directly attached to the jig body, or otherwise. For example, it may be fixed to a suitable support frame or the like, and then attached to the jig body. The size and material of the guide roller are not particularly limited as long as the desired action such as smooth movement of the jig can be achieved. For example, the size of the guide roller can be arbitrarily changed according to the balance with the entire jig. If the guide roller is too small, it may not be possible to stably support the adherend. Further, although the material of the guide roller can be changed in various ways, it is preferable to select the material so that the stiffness of the roller increases as the process proceeds to a later step. For example, if the guide rollers are the first to fourth as described above, it is preferable that the rigidity increases in this order. This is because effects such as that the pressure bonding operation of the adhesive tape can be performed more efficiently can be obtained.

The guide roller can be formed into a rotating roller or other suitable form by molding or the like from a metal material or a plastic material having various sliding properties. Preferably, the guide roller is made of a hard or soft plastic material. It can be formed in the form of a rotating roller. Also, the rotating roller may have various forms within the scope of the present invention, and may be made only of a hard or soft plastic material, or a rotating roller having at least a surface portion formed of an elastic material. It may consist of rollers. Elastic materials include, for example, natural and synthetic rubbers, foamed plastic materials, such as foamed polyurethane,
Various felt materials and the like.

It is preferable that the guide roller is rotatably mounted at a predetermined location, and that a biasing means is mounted on a rotating shaft of the guide roller. This is because the action of the urging means generates elasticity in the movement of the guide roller, and the operation of attaching the adhesive tape to the adherend and pressing the adherend is further promoted. Suitable biasing means include springs, springs, and the like, as described above.

In the winding and attaching jig of the present invention, as described above, each of the constituent members of the jig is attached to the jig main body. As a joining medium, an adhesive may be used, or a bolt and a nut may be used. In the practice of the present invention, the adherend and the pressure-sensitive adhesive tape to be attached thereto are not particularly limited, and those generally used in this technical field may be used as they are, otherwise, any appropriate improvement or Can be used after making changes. For example, the adherend is a wide range of articles such as vehicles such as automobiles, buildings, other structures, machinery, home appliances, and the like. However, when a long article having one or more bent portions in the middle is used as the adherend, the operation and effect of the winding and attaching jig of the present invention can be favorably exhibited. Examples of the adherend having such a specific shape include a frame of a door portion of an automobile, a so-called door sash, and the like.

The pressure-sensitive adhesive tape may be a pressure-sensitive adhesive layer, such as an acrylic adhesive, an epoxy-based adhesive, a urethane-based adhesive, a silicone-based adhesive, or a phenol-based adhesive, on an arbitrary substrate such as paper or plastic material. , A layer of a vinyl chloride adhesive or the like, and a release paper is further provided thereon to protect the pressure-sensitive adhesive layer. The shape of the pressure-sensitive adhesive tape is a roll shape, a sheet shape, a film shape, or the like, and the size thereof is wide ranging from a narrow width to a wide width. If necessary, an adhesive tape that has been shredded in advance according to the shape of the adherend may be used.

The jig for winding and sticking the pressure-sensitive adhesive tape of the present invention is lightweight, compact, and excellent in handleability.
Further, although this winding and attaching jig can be advantageously used for attaching an adhesive tape to various adherends, an adherend which is particularly long and has a bent portion in the middle thereof can be used. When sticking the adhesive tape to the adhesive, the sticking operation can be performed quickly, stably and reliably regardless of the skill level of the worker, and there is no sticking defect caused by insufficient bonding force. Furthermore, in the jig of the present invention, a plurality of adhesive tape winding and attaching members are provided in combination, and the positional relationship between the adhesive tape winding and attaching jig and the adherend can be changed. Easy work of sticking the adhesive tape can be realized.
