BACKGROUND OF THE INVENTION
The present invention relates to a tape sticking jig for peeling and joining a strip-shaped adhesive tape from a mount along a tape sticking surface formed on a workpiece.
[0002]
[Prior art]
Making the interior side of the door sash part of the car matt black means suppressing the reflection of light inside the door sash part when viewed from the outside of the car, especially from the side of the car body. This is desirable for ensuring a clean landscape throughout.
[0003]
For these reasons, it has been conventionally practiced to spray a matte black paint on the door sash. However, spray painting has various problems such as the cost of incidental equipment for maintaining a good working environment and the time taken to dry the paint. Instead, weather resistance, wear resistance, etc. It has been proposed in Japanese Patent Laid-Open Nos. 51-135015 and 62-46780 to stick a good matte black adhesive tape to the door sash. In this case, since the door sash part of the automobile occupies most of the three-dimensional curved surface portion as is well known, the above-described sticking device is extremely large, and when incorporated in an actual production line, The equipment cost of the production line is increased, the followability to the design change of the door sash part is poor, and the versatility is poor.
[0004]
However, if the operator tries to perform this sticking operation only by hand without using any jigs, it is very high work skill level to perform it accurately at a speed corresponding to the automobile production line. Will be required.
[0005]
Therefore, a tape sticking jig disclosed in, for example, Japanese Patent Laid-Open No. 5-338627 has been proposed so that the above-described work can be performed easily and quickly without a skilled worker, and this tape sticking jig is used. Thus, an adhesive tape can be accurately and accurately attached to a predetermined position of the door sash portion without being a skilled worker.
[0006]
[Problems to be solved by the invention]
The conventional tape sticking jig disclosed in Japanese Patent Application Laid-Open No. 5-338627 has a right hand and a left hand corresponding to the right door and the left door of the automobile, respectively. For example, for a sedan type passenger car It is necessary to use four types of tape sticking jigs separately, front and rear, left and right, which is very troublesome.
[0007]
In addition, when the shape of the door sash portion changes depending on the vehicle type, a tape sticking jig corresponding to the shape must be prepared each time, and the flexibility is extremely poor.
[0008]
OBJECT OF THE INVENTION
An object of the present invention is to provide a flexible tape applicator that can easily and quickly apply adhesive tapes to predetermined positions of the left and right door sash portions without requiring skilled workers. It is in.
[0009]
[Means for Solving the Problems]
A tape applicator according to the present invention is a tape applicator for peeling and joining a strip-shaped adhesive tape from a mount along a tape adhering surface formed on a workpiece. A tape guide part provided on the tool body and facing the tape adhering surface formed on the workpiece, and through which the adhesive tape is passed, and the jig body provided on the jig body with respect to the workpiece. The tape guide along the longitudinal direction of the adhesive tape so as to be elastically deformable in a direction opposite to the tape attaching surface and a pair of locking means slidably and detachably engaged along the tape attaching surface A tape pressing means that is formed in a protruding state at least at the center of the part and can press the adhesive tape peeled off from the mount against the tape application surface, and one of the pair of locking means is on the other side. Against these opposites Is attached to the jig body so as to be relatively movable, and between the one locking means and the jig body, the one locking means is biased toward the other locking means. The urging means is interposed .
[0010]
Here, before SL other locking means has a pair of claw portions arranged in parallel along the longitudinal direction of the mount, these claw portions, the positions of the opposing direction of the said one of the locking means It is effective to be fixed to the jig body via a position adjusting means for adjusting.
[0011]
Moreover, it is preferable that the surface of the said tape guide part and the said tape press means is covered with the member of a low friction coefficient.

Is pressed against the tape sticking surface and is stuck to the tape sticking surface.
[0015]
In this case, one of the pair of locking means is mounted on relatively movable in the jig body to these opposing direction relative to the other, between the one of the locking means and the jig body, biasing means for biasing one of the locking means the the other engaging means side and is interposed, one of the locking means to follow the fluctuations and changes in the width of the workpiece and the other engaging means The jig body is always locked to the workpiece without rattling.
If the width of the word over click is extremely different, by operating the position adjusting means the gap between the other pair is a locking means of the claw portion and one of the locking means appropriately changed.
[0016]
Further, when the surfaces of the tape guide portion and the tape pressing means are covered with a member having a low friction coefficient, the frictional resistance when the jig body is moved along the tape adhering surface of the work is reduced.
[0017]
Furthermore, a grip part for gripping the jig body is provided on the opposite side of the tape guide part, and the grip part extends in parallel with a direction perpendicular to the longitudinal direction of the tape attaching surface with a gap from the tape guide part. When the part is formed, the adhesive tape and mount before peeling are passed through the gap between the gripping part and the tape guide, and the adhesive tape is peeled off from the mount and folded back to the tape guide. Only the mount is located in the front.
[0018]
In addition, when the direction which lets an adhesive tape pass is reverse with respect to the tape guide part of a jig | tool main body, a jig | tool main body is moved reversely with respect to the tape sticking surface of a workpiece | work.

A holder block 22 that is opposed to the end block 15 and is in contact with the other side end surface of the adhesive tape 13 is integrally formed on the other end in the width direction of the tape guide portion 12. On the holder block 22, a pair of front and rear guide wall portions 23 are erected in parallel with each other, and a rectangular slide block 24 slides in a direction facing the claw member 18 between the guide wall portions 23. It is stored freely. Further, a guide rod holder 25 facing the sliding block 24 is erected at an end of the holder block 22 opposite to the tape guide portion 12.
[0024]
The jig body 26 in this embodiment is composed of the end block 15, the holder block 22, the guide wall portion 23, the guide rod holder 25 and the like described above.
[0025]
On the upper end of the guide wall portion 23, a holding plate 27 for preventing the slide block 24 from coming off upward from the guide wall portion 23 is fixed via a set screw 28, respectively. Further, on the guide rod holder 25 side of the sliding block 24, a stopper portion that is locked to a stepped portion 29 formed at the center of the holder block 22 and prevents the sliding block 24 from coming off to the end block 15 side. 30 is projected downward. Further, the front end side of the guide rod holder 25 is slidably fitted into a pair of front and rear guide holes 31 formed in the slide block 24 parallel to each other along the width direction of the tape guide portion 12. The base end portions of the pair of front and rear guide rods 32 are screwed, and these guide rods 32 are positioned between the slide block 24 and the guide rod holder 25 so that the slide block 24 faces the end block 15 side. A compression coil spring 33 to be urged is mounted.
[0026]
Therefore, the sliding block 24 is biased toward the end block 15 by the spring force of the compression coil spring 33, and the sliding block 24 can be displaced toward the guide rod holder 25 against the spring force of the compression coil spring 33. It is like that.
[0027]
On the end face of the sliding block 24 on the end block 15 side, there is a protrusion 34 that can be engaged with the inner side of the front door sash portion 17 and can be locked to the front door sash portion 17 with the pair of claw members 18 described above. The jig body 26 can be locked to the front door sash portion 17 by the claw members 18 and the protrusions 34. Further, at the upper end of the sliding block 24, a finger hooking portion 35 for projecting the sliding block 24 toward the guide rod holder 25 against the spring force of the compression coil spring 33 protrudes. .

Therefore, in actual work, the front end of the adhesive tape 13 is peeled off from the mount 41, and the front end of the adhesive tape 13 is moved to a predetermined position (generally, the flat tape adhering surface 42 of the front door sash portion 17). , The slide block 24 is pulled away from the claw member 18 by using the finger hook portion 35, and the tape guide portion 12 of the jig body 26 and the adhesive tape 13 are held while maintaining this state. The jig body 26 is pressed against the front door sash part 17 so that the portion of the tape attaching surface 42 to which the tip part is attached is overlapped, and the finger is released from the finger hooking part 35, and by the spring force of the compression coil spring 33, The claw member 18 and the protruding portion 34 are locked to the front door sash portion 17. Thereby, the tape pressing sheet 14 is elastically deformed so as to be crushed, and the adhesive tape 13 is pressed against the tape attaching surface 42.
[0030]
From this state, when the jig body 26 is moved in the left direction in FIG. 6 along the tape attaching surface 42 while peeling the adhesive tape 13 from the mount 41, the tape guide portion 12 is displaced from the tape attaching surface 42. The restrained pressure-sensitive adhesive tape 13 is pressed against the tape sticking surface 42 with elastic deformation of the tape pressing sheet 14, and is stuck to the tape sticking surface 42.
[0031]
Here, since the sliding block 24 is always urged toward the pair of claw members 18 by the spring force of the compression coil spring 33, the sliding block follows the variation and change in the width of the front door sash portion 17. 24 is displaced in the direction facing the claw member 18, and the jig body 26 can be locked to the front door sash portion 17 without rattling with respect to the claw member 18. Further, since the surfaces of the tape guide portion 12 and the tape pressing sheet 14 are covered with the low friction coefficient member 11, the jig body 26 is moved along the tape attaching surface 42 of the front door sash portion 17. This reduces the frictional resistance and makes this operation easy.
[0032]
Thus, after sticking the adhesive tape 13 on the tape sticking surface 42 of the front door sash part 17, the width direction both ends of the adhesive tape 13 are made the remaining part of the front door sash part 17 using the squeeze roller which is not illustrated. Paste to the part. In this state, since the adhesive tape 13 is already positioned with respect to the front door sash portion 17, the work can be performed without any problem.
[0033]
Although it is possible to position the adhesive tape 13 and the mount 41 on the front side in the traveling direction as shown in FIG. 5, they are placed in the gap 39 between the gripping member 36 and the tape guide portion 12 as shown in FIG. It is also effective to further improve the workability by folding the adhesive tape 13 toward the tape guide portion 12 so that only the mount 41 is positioned in front of the jig body 26 in the moving direction.
[0034]
Further, since the front door sash portion 17 described above is usually symmetrical with respect to the vehicle body of the automobile, the direction in which the adhesive tape 13 passes through the tape guide portion 12 according to the left-right direction is illustrated. 5 and FIG. 6 can be reversed, and the jig main body 26 can be moved in the reverse direction with respect to the tape adhering surface 42 of the front door sash portion 17 to cope with the situation.
[0035]
Furthermore, when the width and shape of the front door sash portion 17 are extremely different due to the difference in the vehicle type or the like, the fixing bolt 19 is loosened to appropriately shift the position of the claw member 18, or the claw member 18 and the sliding block It is possible to adjust and cope by replacing 24 with another shape.
[0036]
【The invention's effect】
