Description

  The present invention relates to a bonding jig for an adhesive tape.

  Conventionally, instead of performing complicated work such as spray coating using a black paint on the inside and outside of a window frame (door sash) formed on a door panel of an automobile, adhesion with excellent weather resistance and abrasion resistance It is known to impart a good view with light load operations such as applying a tape.

  Patent Document 1 proposes a sticking jig for easily sticking such an adhesive tape without relying on a skilled worker. In the sticking jig described in Patent Document 1, the width of the window frame is made to follow that the width dimension of the sticking face of the window frame changes along the longitudinal direction of the window frame (the sticking direction of the adhesive tape). The separation width of the guide rollers sandwiching from both sides of the direction is configured to be displaced along with the change of the width dimension.

  On the other hand, the width dimension of the adhesive tape is uniformly increased with respect to the change of the width dimension of the pasting surface of the window frame. For example, if the width dimension on the sticking start side of the sticking surface is 50 mm, the width dimension on the sticking end side is 60 mm, and the increase is 10 mm, the width dimension on the sticking start side of the adhesive tape is 70 mm, sticking The width dimension at the end side is 80 mm, and the increase is also 10 mm. That is, in the conventional adhesive surface and adhesive tape, the adhesive tape protrudes with a certain amount (20 mm) in the width direction with respect to the adhesive surface at any location in the longitudinal direction. Therefore, in the conventional sticking jig, the adhesive tape may be attached while the separation width of the guide roller is displaced, and the attachment state of the adhesive tape to the sticking jig according to the sticking surface where the width dimension changes It can be reliably maintained and can be stuck well without misalignment.

[Schematic description of adherend and adhesive tape]
Hereinafter, the present embodiment will be described based on the drawings.
In FIG. 1 and FIG. 2, the adherend according to the present invention is the vertical window frame portion 3 which constitutes the front door panel 2 of the passenger car 1. In the vertical window frame portion 3, the adhesive tape AT is attached by the attaching jig 10 to the attaching face 3 </ b> A on the outer side thereof. At this time, the sticking boundary 3B of the sticking surface 3A is set near the left edge of the vertical window frame portion 3 in FIG. 2 and the adhesive tape AT is stuck to the sticking surface 3A. It protrudes from the right edge in the figure. The portion protruding from the pasting surface 3A in the width direction is bent twice along the edge in the longitudinal direction (consistent with the pasting direction) and pasted over a second guide surface 3D described later (see FIGS. 4 and 6) Refer to the two-dot chain line).

  Further, in the vertical window frame portion 3, the width dimension of the pasting surface 3A changes along the longitudinal direction, and from the pasting start side (upper side in FIG. 2) to the pasting end side (lower side in FIG. 2) It becomes large from width dimension w1 to width dimension w2 as it goes. On the other hand, the width dimension of the adhesive tape AT also changes along its longitudinal direction, and increases from the width dimension W1 to the width dimension W2 from the sticking start side toward the sticking end side. However, the degree of change in the width dimension of the adhesive tape AT is larger than the degree of change in the width dimension of the bonding surface 3A.

  That is, the relationship between the width dimensions w1, w2, W1, and W2 on the sticking start side and the sticking end side is (w2-w1) <(W2-W1). Also, assuming that the amount of protrusion of the adhesive tape AT in the width direction from the adhesive surface 3A on the sticking start side and sticking end side is EX1 and EX2, the protrusion amounts EX1 and EX2 and the width dimensions w1, w2, W1 and W2 The relationship is that EX1 = W1-w1 and EX2 = W2-w2, and the protruding amounts EX1 and EX2 have a relationship of EX1 <EX2. That is, in the present embodiment, the width dimension of the adhesive tape AT does not increase uniformly with the increase of the width dimension of the sticking surface 3A unlike the prior art, and the protrusion amount of the adhesive tape AT goes to the sticking end side large. Therefore, the right edges along the longitudinal direction of the bonding surface 3A and the adhesive tape AT do not become parallel to each other.

  Here, the adhesive tape AT has a configuration in which the adhesive AD is provided on one surface of the base sheet BS, and is temporarily attached to a release sheet RL such as a release paper or a release film via the adhesive AD. In addition, the release sheet RL is provided with divided portions (see dotted line positions in FIG. 2) in a portion close to the sticking start side, and the lower release sheet RL1 is bounded by the sticking jig 10 with the portion as a boundary. In the part that is peeled off automatically, the upper peeling sheet RL2 is a part that is peeled by the worker after the sticking operation.

  The first guide roller 31 is provided on the lower surface of the locking block 22 of the base frame 20. The second guide roller 32 is provided at the tip of a substantially L-shaped holding lever 33. The holding lever 33 has a grip portion 34 protruding upward, and a mounting plate 35 bent with respect to the grip portion 34 and having a second guide roller 32 attached at its tip. Is rotatably supported at the lower side of the operation block 21. At this time, a torsion coil spring (not shown) is inserted through the rotation shaft 33A, and the tip end side of the holding lever 33, that is, the second guide roller 32 faces the second guide surface 3D by the biasing force of the torsion coil spring. The vertical window frame 3 acts to hold the sticking jig 10.

  The pressing means 40 includes a pair of pressing rollers 41. The pressure roller 41 is formed by covering the surface of a sleeve-like member (not shown) with a rubber-like elastic material such as foamed resin, and is inserted into the connecting shaft 23 connecting the operation side block 21 and the locking side block 22 The outer periphery is rotated with the connecting shaft 23 as a rotating shaft.

  The mounting means 50 has an L-shaped mounting lever 51. The mounting lever 51 has a gripping portion 52 protruding upward, and a gripping plate 53 provided with a gripping surface 53A which is bent with respect to the gripping portion 52 and is brought close to and separated from the pressing roller 41. It is pivotally supported on the upper side of the operation side block 21 in the vicinity of the bending portion which is a continuous portion of the gripping portion 52 and the holding plate 53. At this time, a torsion coil spring (not shown) is also inserted through the rotation shaft 51A, and the pressing lever 41 has the tip of the mounting lever 51 mounted on the locking side block 22 by the biasing force of the torsion coil spring. Between the adhesive tape AT and the release sheet RL1. In the following description, the description of the release sheet RL1 integral with the adhesive tape AT may be omitted.

  The mounting means 50 also has a pair of locking pieces 54 attached to the locking block 22. A part of the locking piece 54 protrudes upward in the pressure roller 41 side. When the adhesive tape AT is mounted between the pressing roller 41 and the holding plate 53, the adhesive tape AT wound around the pressing roller 41 is locked to the locking piece 54 and is prevented from being detached from the pressing roller 41.

  The biasing means 60 is displaceable following the width dimension of the adhesive tape AT which changes along the sticking direction, and is provided on the holding plate 53 of the mounting means 50. Specifically, the biasing means 60 is erected through the sliding lever 61 sliding along the axis of the pressing roller 41 in the plane of the holding plate 53 and the sliding lever 61, and bonding is performed on the lower end side thereof A moving pin 62 with which one edge AT1 of the tape AT contacts and is locked, a fixing pin 63 erected on the tip end side of the holding plate 53, a tension bridged between the moving pin 62 and the fixing pin 63 A coil spring 64 is provided.

  Among them, the tension coil spring 64 biases the sliding lever 61 toward the leading end side of the holding plate 53 via the moving pin 62 and biases the adhesive tape AT toward the other edge AT2. Here, the sliding lever 61 is folded from one end of the sliding piece 65 and a sliding piece 65 that slides in a state of being accommodated in a guide groove 53C provided around the opening 53B of the holding plate 53. It is formed in L shape by the holding part 66 installed bent and standing.

  The contact means 70 is formed by an inner wall 71 facing the operation side block 21 in the locking side block 22. That is, the adhesive tape AT is mounted between the inner wall 71 and the moving pin 62 in a state of being pressed against the inner wall 71 by the biasing means 60 having the tension coil spring 64.

[Explanation of pasting work]
Hereinafter, the procedure of the sticking operation using the sticking jig 10 will be described.
First, the operator grips the grip portion 52 of the mounting lever 51 of the sticking jig 10, rotates the mounting lever 51 outward with respect to the base frame 20, and opens the mounting lever 51 and the pressing roller 41. After that, as shown in FIG. 2, FIG. 4 and FIG. 5, the adhesion start side (small width side) of the adhesive tape AT from which the release sheets RL1 and RL2 are separated is the lower side of the pressure roller 41 together with the release sheet RL2. And the holding lever 33 in such a way as to be folded back, and its end is pulled out in the direction opposite to the pasting direction.

  Thereafter, while gripping the gripping portion 52 of the mounting lever 51 and the gripping portion 66 of the sliding lever 61 together, the mounting lever 51 is returned to the original position, and the adhesive tape AT before sticking is mounted together with the release sheet RL1. It is held between the lever 51 and the pressing roller 41 to complete the attachment of the adhesive tape AT to the attaching jig. As a result, the adhesive tape AT contacts the inner wall 71 of the locking block 22 while being urged, and in this state, is attached between the inner wall 71 and the moving pin 62. At this time, to hold the holding portion 66 of the sliding lever 61 together with the holding portion 52 of the mounting lever 51, move the moving pin 62 toward the holding portion 52 against the biasing force of the tension coil spring 64. The reason is to avoid that the lower end of the moving pin 62 interferes with the adhesive tape AT when the mounting lever 51 is returned.

  Next, the holding side block 22 of the sticking jig 10 on which the adhesive tape AT is mounted and the holding portion 34 of the holding lever 33 are gripped together, and the holding lever 33 is held as shown by a two-dot chain line in FIG. The sticking jig 10 is rotated in the vertical window frame portion 3 so that the second guide roller 32 at the leading end is separated from the pressing roller 41 side and the first guide roller 31 abuts on the first guide surface 3C in this state. Release the grip of the holding lever 33 to bring the second guide roller 32 into contact with the second guide surface 3D, and the second guide roller 32, the first guide roller 31, and the pressing roller 41 Hold the part 3 and complete the installation of the attaching jig 10 on the vertical window frame part 3. In addition, when installing the sticking jig 10, the end of the adhesive tape AT (the part to which the peeling sheet RL2 is temporarily attached) drawn out in the sticking direction reverse direction is aligned with the sticking start position 3E on the sticking surface 3A. .

  Subsequently, the operation side block 21 and the locking side block 22 of the base frame 20 are gripped together, and the adhesive tape AT is pressed against the sticking surface 3A via the pressing roller 41 so that the sticking jig 10 is in the sticking direction Move it. Along with this movement, as shown in FIG. 8, the adhesive tape AT is peeled off from the release sheet RL1 at the return portion at one pressing roller 41, and the peeled adhesive tape AT is attached to the sticking surface 3A, and the release sheet RL1. Is discharged to the sticking direction side.

  At this time, due to the change in cross sectional shape of the vertical window frame portion 3, the width dimension of the sticking surface 3A gradually increases from the width dimension w1 at the start of sticking to the end of sticking, and is close to the width dimension w2 just before the end of sticking It grows in size (see Figure 2). Similarly, the width dimension of the adhesive tape AT also gradually increases between the width dimension W1 at the start of application and the end of application, and increases to a size close to the width dimension W2 immediately before the end of application.

  Then, in the bonding jig 10 of the present embodiment, with the change of the width dimension of the adhesive tape AT, the moving pin 62 in contact with the edge AT1 of the adhesive tape AT moves against the biasing force of the tension coil spring 64. And keep the attached state of the adhesive tape AT while following the change of the width dimension. As a result, the moving pin 62 moves by the change of the width dimension of the adhesive tape AT regardless of the change of the width dimension of the bonding surface 3A. In addition, even if the width dimension of the tension coil spring 64 is small on the side where the adhesive tape AT is attached, the adhesive tape AT can be reliably urged and attached to the inner wall 71, and the adhesion end side of the adhesive tape AT Even if the width dimension becomes large, the spring force is set to such an extent that the edge AT1 of the adhesive tape AT contacting via the moving pin 62 is not broken.

  Further, after the sticking jig 10 is moved to the predetermined position in the sticking direction and the sticking of the adhesive tape AT peeled off from the peeling sheet RL1 is finished, the holding lever 33 is operated to remove the sticking jig 10 from the vertical window frame portion 3 . Thereafter, the worker peels off the release sheet RL2 on the sticking start side and sticks the adhesive tape AT of that portion to the sticking surface 3A. Finally, as shown in FIG. 4 and FIG. 6, the adhesive tape AT protruding from the pasting surface 3A is bent twice and pasted to the surface opposite to the first guiding surface 3C and the second guiding surface 3D, and pasting work To complete.

[Effect of the embodiment]
According to the present embodiment, the adhesive tape AT is mounted between the contact means 70 in a state of being biased by the biasing means 60, and the bias means 60 follows the change in the width dimension of the adhesive tape AT. Therefore, the adhesive tape AT can be reliably attached without being affected by the degree of change in the width dimension of the pasting surface 3A of the vertical window frame portion 3, and the adhesive tape AT is maintained in the attached state. Can be affixed to
