[Prior art]
Matting black on the inside and outside of a car door sash reduces reflection of light from the door sash when viewed from the outside of the car, particularly from the side of the car body. It is desirable to secure the landscape.
[0003]
For these reasons, it has been conventionally practiced to spray and paint 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 Application Laid-Open Nos. 51-135015 and 62-46780 to stick a good matte black adhesive tape to a door sash. In this case, since the door sash of an automobile is mostly composed of a three-dimensional curved surface as is well known, the above-described sticking device is extremely large, and if it is incorporated into an actual production line, it is produced. The equipment cost of the line increased, the followability to the design change of the door sash was poor, and the versatility was 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 applicator disclosed in, for example, Japanese Patent Application Laid-Open No. 5-338627 has been proposed so that the above-described operation can be performed easily and quickly without a skilled worker. By using this tape applicator, Thus, an adhesive tape can be accurately and accurately attached to a predetermined position of the door sash without being a skilled worker. In addition, a device for automatically assembling a weather strip to a door sash, such as those disclosed in Japanese Patent Application Laid-Open No. 2-221582, Japanese Patent Application Laid-Open No. 3-166068, or Japanese Patent Publication No. 5-65298, is also applicable.

[Problems to be solved by the invention]
The conventional tape applicator 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 car, respectively. For example, for a sedan type passenger car It is necessary to use four types of tape applicators separately, front and rear, left and right, which is very troublesome. In addition, the structure is complicated, the number of parts is large, and the manufacturing cost increases.
[0007]
On the other hand, when the weather strip mounting device disclosed in Japanese Patent Laid-Open No. 2-221582, Japanese Patent Laid-Open No. 3-166068, or Japanese Patent Publication No. 5-65298 is applied to a tape applying device, the door panel is held. In addition to the positioning device, a space for installing the manipulator is required, and there is a problem that it is impossible to cope with this unless the production line of the automobile is changed.

That is, three sets of bolt through-holes 13a, 13b, and 13c are provided at predetermined intervals in the pressing roller bracket 11 and the sub body 12 constituting a part of the main body 10, respectively. One roller support connecting bolt 14 is inserted into the bolt through hole 13b in the central portion of the pressing roller bracket 11 and the sub body 12, and the roller support connecting bolt 14 is covered with a rubber elastic body 15 on the outer periphery. The pressure roller bracket 11 and the sub body 12 are connected to the roller support connecting bolt 14 and the auxiliary pressure roller by lock nuts 17 that pass through the auxiliary pressure roller (first pressure roller) 16 rotatably and are screwed into both ends thereof. 16 are connected together. Since the distance between the pressure roller bracket 11 and the sub-body 12 needs to be set appropriately according to the length of the auxiliary pressure roller 16 and the width of the adhesive tape A, the center portion of the roller support connecting bolt 14, that is, the auxiliary pressure roller The fitting part with 16 has a step set larger than the inner diameter of the bolt through hole 13b, and the distance between the pressing roller bracket 11 and the sub body 12 substantially corresponds to the length of the large diameter part. .
[0018]
Since the auxiliary pressing roller 16 is made to peel from the peeling material B by winding the adhesive tape A as will be described later, the outer diameter of the auxiliary pressing roller 16 is from the viewpoint of maintaining the peelability of the adhesive tape A with respect to the peeling material B well. Is preferably as small as possible.
[0019]
Of the remaining two sets of bolt through holes 13a and 13c, the auxiliary pressure roller 16 is used as a reference for the pressure roller bracket 11 on the downstream side of the adhesive tape A in the sticking direction and the bolt through hole 13c of the sub body 12 for supporting the roller. A connecting bolt 14 is inserted, and this roller supporting connecting bolt 14 passes through a main pressing roller (second pressing roller) 19 whose outer peripheral portion is covered with a rubber-like elastic body 15 so as to be rotatable. The pressing roller bracket 11 and the sub body 12 are integrally connected via the roller supporting connecting bolt 14 and the main pressing roller 19 by the lock nut 17 to be screwed. The main pressing roller 19 in this embodiment has the same basic configuration as the auxiliary pressing roller 16, but the outer diameter is set slightly larger than the outer diameter of the auxiliary pressing roller 16. Even when the pressing force of the 20 against the tape application surface 21 is larger than that of the auxiliary pressure roller 16, the tape application surface 21 of the door outer sash 20 is slightly curved in the direction facing the auxiliary pressure roller 16 and the main pressure roller 19. The adhesive tape A is reliably brought into close contact with the tape application surface 21 of the door outer sash 20.
[0020]
As will be described later, when the tape sticking apparatus 1 is in use, the adhesive tape A extends almost halfway around the auxiliary pressure roller 16 so that the adhesive surface faces outward with respect to the auxiliary pressure roller 16 and the main pressure roller 19. However, the release material B holding the adhesive tape A is pulled out from the tape applicator 1 along the door outer sash 20.
[0021]
A guide roller bracket 23 constituting a part of the main body 10 is integrally fixed to the pressure roller bracket 11 via a connecting screw 24, and between the guide roller bracket 23 and the pressure roller bracket 11. The auxiliary pressing roller 16 and the main pressing roller 19 sandwich a flexible pressing plate 25 for sandwiching a panel member constituting the tape application surface 21 of the door outer sash 20. Further, the guide roller bracket 23 is engaged with a pair of first guide rollers 26 capable of contacting the inner side surface opposite to the tape application surface 21 of the door outer sash 20 and a weather strip mounting portion of the door outer sash 20. A plurality of possible (three in the illustrated example) second guide rollers 27 are rotatably attached.
[0022]
Auxiliary brackets 28 a and 28 c are provided on both sides of the guide roller bracket 23 along the arrangement direction of the second guide rollers 27, and these auxiliary brackets 28 a and 28 c are arranged in parallel with the second guide roller 27. A screw hole 30 for attaching the third guide roller 29 is formed, and the third guide roller 29 can be replaced via the attachment screw 31 in the screw hole 30 of the auxiliary bracket 28a located on the upstream side in the sticking direction of the adhesive tape A. It is screwed to.
[0023]
These guide rollers 26, 27, 29 are formed of a polymer resin material or the like and a bearing (see FIG. 3) 32 is incorporated in order to reduce rotational wear associated with the movement of the tape applicator 1 relative to the door outer sash 20. In this embodiment, the pressure roller bracket 11, the guide roller bracket 23, and the auxiliary brackets 28a and 28c constitute the main body 10 of the present invention (see FIG. 4).
[0024]
The rotation axes of the first guide rollers 26 are set substantially parallel to the rotation axes of the auxiliary pressure roller 16 and the main pressure roller 19, and the rotation axes of the second guide roller 27 are the first guide rollers 26. The auxiliary pressing roller 16 and the main pressing roller 19 are set so as to be substantially orthogonal to the rotation axis, but their layout can be appropriately changed according to the shape of the door outer sash 20. Alternatively, when the width and shape of the door outer sash 20 are different due to the difference in vehicle type, etc., a certain degree of versatility can be obtained by replacing the first guide roller 26 and the second guide roller 27 with different shapes and sizes. Can be given.
[0025]
In this embodiment, when the tape applicator 1 is set on the door outer sash 20 in the correct state as shown in FIG. 2, the door outer sash 20 is connected to the auxiliary pressing roller 16, the main pressing roller 19 and the first guide roller 26. The panel member constituting the tape application surface 21 of the door outer sash 20 is sandwiched between the auxiliary pressing roller 16, the main pressing roller 19, and the pressing plate 25, and the auxiliary pressing roller 16 and the main pressing roller 19 are applied with the tape. It will be in the state pressed against the surface 21.
[0026]
Both ends of a pivot 33 that is orthogonal to the roller supporting connecting bolt 14 and substantially parallel to the tape application surface 21 are rotatably fitted to the sub-body 12, and the pivot 33 penetrates the base end. The tape guide plate 34 fixed in a state is pivotally supported about the pivot 33 with respect to the sub-body 12, and can be opened and closed between an open position shown in FIG. 1 and a closed position shown in FIG. ing. The tape guide plate 34 is disposed on the opposite side of the second guide roller 27 with the auxiliary pressure roller 16 and the main pressure roller 19 interposed therebetween. In the closed position, the tape guide plate 34 is connected to the auxiliary pressure roller 16 and the main pressure roller 19. A gap 35 for passing the adhesive tape C with a release material is formed between them. When the tape applicator 1 is set on the door outer sash 20 in the correct state as shown in FIG. 2, the tape guide plate 34 is positioned substantially parallel to the tape application surface 21.
[0027]
In the closed position of the tape guide plate 34, a pair of projections 36a and 36c projecting into the gaps 35 on both sides in the rotational direction of the auxiliary pressing roller 16 are provided on the tape guide plate 34, and one of the projections 36c is assisted. An appropriate tension can be applied to the adhesive tape A by being positioned between the pressing roller 16 and the main pressing roller 19.
[0028]
In order to maintain the closed position of the tape guide plate 34 shown in FIG. 2, a permanent magnet 37 is embedded in the tip portion of the tape guide plate 34 (see FIG. 3), and the mild steel plate 38 is pressed against the pressure roller bracket so as to face this. 11, and the permanent magnet 37 and the mild steel plate 38 constitute the fixing means of the present invention. The attraction force by the magnetic force acting between them is sufficient that the operator can easily open it, and the closed position of the tape guide plate 34 is set in addition to using the magnetic force as in the present embodiment as the fixing means. It is of course possible to employ other fixing means that can be held.
[0029]
Therefore, in actual work, the attachment positions of the main pressing roller 19 and the third guide roller 29 are changed according to the moving direction of the tape applying device 1 with respect to the tape applying surface 21 of the door outer sash 20. For example, in the state shown in FIG. 5, when the tape applicator 1 is moved to the near side (in the direction of arrow F in FIG. 5) with respect to the tape application surface 21 of the door outer sash 20, the layout as described above is adopted as it is. However, when it is necessary to move in the opposite direction, the lock nut 17 (see FIG. 3) is removed from the roller support connecting bolt 14 and the roller support connecting bolt 14 and the pressure roller bracket 11 and the sub body 12 are removed. The main pressing roller 19 is removed, and the roller supporting connecting bolt 14 to which the main pressing roller 19 is attached is inserted into the bolt through hole 13 a that is not used, and is fixed again by the lock nut 17. At the same time, the mounting screw 31 is removed together with the third guide roller 29 from the auxiliary bracket 28a to which the third guide roller 29 (see FIG. 4) is attached, and this is attached to the auxiliary bracket 28c to which the third guide roller 29 is not attached. Installing.
[0030]
On the other hand, the front end of the release material B is peeled off from the adhesive tape C with the release material, and the front end of the adhesive tape A is moved to a predetermined position (generally, an adhesion start position) of the flat tape application surface 21 of the door outer sash 20. 1), the tape guide plate 34 of the tape applicator 1 which has been switched in advance as described above is opened as shown in FIG. 1, and the auxiliary pressing roller 16 and the main pressing roller 19 are adhered to each other. The first guide roller 26 and the second guide roller 27 are engaged with the door outer sash 20 so as to press the tip of the tape A against the tape application surface 21.
[0031]
Next, the adhesive tape A is wound around the auxiliary pressing roller 16 halfway, and the release material B is pressed against the auxiliary pressing roller 16 and the main pressing roller 19 so as to be substantially parallel to the tape application surface 21, as shown in FIGS. The tape guide plate 34 is fixed to the closed position.
[0032]
In this case, in this embodiment, the pivot shaft 33 is attached to the sub body 12 so that the tape guide plate 34 in the open position hangs downward from the sub body 12 and the adhesive tape A is wound around the auxiliary pressure roller 16 and the main pressure roller 19. In this case, the operator does not need to hold the tape guide plate 34 in the open position, and the above workability can be maintained well.
[0033]
From this state, when the tape applying device 1 is moved in the left direction in FIG. 5 along the tape applying surface 21 while peeling the adhesive tape A from the adhesive tape C with the release material, the gap portion 35 causes a deviation from the tape applying surface 21. Is pressed against the tape application surface 21 with the elastic deformation of the auxiliary pressure roller 16 and the main pressure roller 19, and is adhered to the tape application surface 21. At the same time, the used release material B is The tape sticking device 1 is pushed forward in the moving direction. In this case, since the outer diameter dimension of the auxiliary pressing roller 16 is minimized in this embodiment, the adhesive tape A can be reliably peeled from the release material B, and the outer diameter dimension of the main pressing roller 19 Is set to be larger than the external dimension of the auxiliary pressing roller 16, so that even if the tape application surface 21 of the door outer sash 20 is slightly curved in the direction facing the auxiliary pressing roller 16 and the main pressing roller 19, The pressure-sensitive adhesive tape A is attached in a state where the pressure-sensitive adhesive tape A is accurately positioned with respect to the tape application surface 21 by the pressing roller 16, and then the pressure-sensitive adhesive tape A is strongly and reliably pressed against the tape application surface 21 by the main pressure roller 19. it can.
[0034]
The positions of the bolt through holes 13a and 13c for the roller supporting connecting bolt 14 to which the main pressing roller 19 is attached are closer to the tape application surface 21 side of the door outer sash 20 than the bolt through hole 13b for the auxiliary pressing roller 16 is. In this case, the same effect can be obtained even if the outer diameter of the main pressing roller 19 is set smaller than the outer diameter of the auxiliary pressing roller 16.
[0035]
Here, the main body 10 follows the door outer sash 20 without being rattled by the first guide roller 26, the second guide roller 27, and the third guide roller 29, and the guide rollers 26, Since 27 and 29 are made of members having a low friction coefficient, the frictional resistance when the tape applying device 1 is moved along the tape applying surface 21 of the door outer sash 20 is reduced, and this attaching operation is easily performed. be able to. In particular, the presence of the third guide roller 29 makes it easy for the moving direction of the tape applying device 1 to be regulated along the tape applying surface 21, and the moving workability of the tape applying device 1 is improved.
[0036]
Thus, after sticking adhesive tape A to the tape sticking surface 21 of the door outer sash 20, the tape sticking apparatus 1 is removed from the door outer sash 20, and the width direction both ends of the adhesive tape A are used using the squeeze apparatus which is not shown in figure. The part is affixed to the remaining part of the door outer sash 20. In this state, since the adhesive tape A is already positioned with respect to the door outer sash 20, the operation can be performed without any problem.
[0037]
In the embodiment described above, the lock nut 17 is removed and the attachment position of the main pressing roller 19 is changed. However, a mechanism for changing the attachment position of the main pressing roller 19 by one touch can also be adopted. .
[0038]
FIG. 6 shows the external appearance of another embodiment of the tape applicator according to the present invention, and FIG. 7 shows the fracture structure of the main part thereof. The description will be omitted, and the redundant description will be omitted. That is, the base end portions of a pair of swivel arms 39 are pivotally attached to the roller supporting connecting bolts 14 between the longitudinal end portions of the auxiliary pressing roller 16 and the pressing roller bracket 11 and the sub body 12. The main pressing roller 19 is rotatably fitted to a pin 40 having both ends connected to the tip of the swivel arm 39.
[0039]
In order to regulate the position of the main pressing roller 19 via the swivel arm 39, two sets of ball plungers 42a and 42c incorporating balls 41 that can be projected and retracted by elastic force are embedded in the pressing roller bracket 11 and the sub body 12, respectively. The ball 41 at the tip is biased in a protruding state from the surfaces of the pressure roller bracket 11 and the sub body 12. Corresponding to these ball plungers 42a and 42c, the swivel arm 39 is formed with a pair of recesses 43 in which the balls 41 at the tips of the ball plungers 42a and 42c can be locked.
[0040]
Therefore, when it is necessary to switch the position of the main pressing roller 19, the main pressing roller 19 is rotated 180 degrees around the roller supporting connecting bolt 14 together with the swing arm 39 from the state shown in FIG. The tip of the other ball plunger 42a only needs to be locked to the recess 43, and the attachment position of the main pressing roller 19 can be switched very easily and quickly.
[0041]
In the two embodiments described above, the mounting position of the third guide roller 29 with respect to the pair of auxiliary brackets 28a, 28c is switched. However, the second guide roller 27 and the third guide roller 29 as a whole are arranged along the arrangement direction. By deviating, it is possible to cope with a change in the sticking direction of the adhesive tape A, and an arbitrary configuration can be adopted as a method for changing the attachment positions of the rollers 19 and 29.
[0042]
【The invention's effect】
According to the tape sticking device of the present invention, the attachment positions of the second pressing roller and the third guide roller can be switched according to the sticking direction of the adhesive tape. It can be used and can be manufactured at low cost because the mechanism is simple.
[0043]
In addition, since the third guide roller is disposed in an offset state upstream of the adhesive tape sticking direction with respect to the first pressing roller, it is easy to regulate the moving direction of the tape sticking device along the work, Since the tape applicator can always be engaged without rattling, the adhesive tape can be accurately applied to the tape application surface of the workpiece without being a skilled worker. In particular, when the tape sticking device is moved along the workpiece, the first and second pressing rollers and the first and second guide rollers are structured to roll with respect to the workpiece. The frictional resistance during the movement of the tape is reduced, the tape sticking operation can be easily performed with a small operating force, and damage due to the friction of the adhesive tape surface does not occur.
[0044]
Further, when the mounting position of the second pressing roller is changed by the turning operation of the second pressing roller around the rotation axis of the first pressing roller, the switching operation of the mounting position is quickly performed. It is possible to greatly improve the usability.
[0045]
Furthermore, when the outer peripheral surface of the pressing roller is formed of a rubber-like elastic body, air can be prevented from being mixed and the adhesive tape can be applied evenly to the tape application surface.
[0046]
When magnetic force is used as the fixing means, the fixing means can be made compact and the tape guide plate can be opened and closed quickly and easily.
