DETAILED DESCRIPTION OF THE INVENTION
A preferred embodiment of an adhesive tape sticking jig according to the present invention will be described below with reference to FIGS.
[0017]
The door sash frame F to which the adhesive tape is attached by this jig has a frame main body portion F1 having a surface to which the adhesive tape T is to be applied, and a back surface of the frame main body portion F1, as shown in FIG. A reinforcing bulge portion F2 projecting on the side and a weather strip mounting portion F3 provided on the outside of the reinforcing bulge portion F2 are integrally formed. In the following description, an embodiment of an adhesive tape attaching jig suitable for attaching an adhesive tape to the inner surface of a door sash frame F having such a configuration will be described.
[0018]
The adhesive tape sticking jig 1 has a base 2 and a pressing lever 3 attached to the base 2. A groove-type guide 4 is formed on the base 2, and bottom guide rollers 5, 5 aligned in the guide direction are provided at the groove bottom of the groove-type guide 4.
[0019]
In addition, an elastic roller 6 a constituting the pressing portion 6 is attached to the base portion 2 in order to press the adhesive tape T, and the rotation shaft of the elastic roller 6 a is disposed so as to intersect the guide direction of the grooved guide 4. ing.
[0020]
The pressing lever 3 is pivotally attached to the base 2 so as to be rotatable. The pressing lever 3 includes a pressing roller 7 constituting a pressing element at the tip, and is elastically biased by a torsion spring 8 (FIG. 8) so that the pressing roller 7 is pressed toward the bottom guide rollers 5. Yes.
[0021]
Thus, the elastic roller 6a, the bottom guide rollers 5 ... 5, and the pressing roller 7 can constitute a clamping means for slidably clamping the door sash frame F. The elastic roller 6a can be formed by winding the rotating shaft with an elastic body such as soft rubber or sponge.
[0022]
When joining the adhesive tape T with the elastic roller 6a to the door sash frame F, soft in the direction of joining the adhesive tape T by applying a force to the elastic roller 6a, the elastic roller 6a of the door sash frame F In order to be freely deformed along the outer shape, the adhesive tape T can be adhered to the door sash frame F without causing bubbles to enter. However, when the elastic roller 6a comes into close contact with the outer shape of the door sash frame F, the contact area is increased, and since a pressing force is applied, a slightly large frictional force is generated between the adhesive tape T and the elastic roller 6a. May occur. There is no problem when the straight portion of the door sash frame F is pasted. However, when the elastic roller 6a changes the direction of the curved portion in the curved portion, if the frictional force with the adhesive tape T is large, the elastic roller 6a is elastic. The roller 6a twists the adhesive tape T, and the position of the adhesive tape T may not be stable. In addition, since the adhesive tape T is twisted, the adhesive tape T may be wrinkled. Therefore, by using a foamed material such as sponge rubber as the material of at least the surface layer of the elastic roller 6a , even foamed materials such as natural rubber, synthetic rubber, and silicone rubber can be cut. The surface obtained by doing so has an extremely low frictional force compared to a material without foaming on the contact surface. Therefore, by using the foam material for the elastic roller, the curved portion of the door sash frame F also realizes the desired stable position of the adhesive tape T in the same manner as the straight portion, and the adhesive tape T is prevented from getting wrinkles. be able to.
[0023]
Side guide rollers 4 a... 4 a can be provided on the side of the groove-type guide 4. The side guide rollers 4a... 4a can constitute guide means for slidably guiding the door sash frame F.
[0024]
The elastic roller 6 a is supported by bearing portions 2 a and 2 a that are protruded on both sides of the base portion 2. A gap H through which the adhesive tape T can sufficiently pass is formed between the elastic roller 6a and the base 2 (see FIG. 9). Through the gap H, the pressing direction of the pressing portion 6 (arrow P in FIG. 9) is placed on the base 2 in front of the jig sliding direction of the pressing portion 6 (direction in which the jig slides: arrow X direction in FIG. 9). (Direction) It is formed so as to communicate with the vicinity of the pressing position of the pressing portion 6 from the rear position, whereby the tape introduction path K can be configured (FIGS. 9 and 7B).
[0025]
Slide grooves 2b and 2b are formed on the inner surfaces of both side walls of the base portion 2 over the inner walls of the bearing portions 2a and 2a (see FIG. 1), and a slide plate 9 constituting a movable portion is formed in the slide grooves 2b and 2b. It is slidably fitted. The sliding plate 9 is formed with a hole 9a for hooking a finger (FIG. 7).

Can be configured by forming recesses into which the balls of the ball plunger are fitted in the slide grooves 2b and 2b. Further, the second locking means forms a step 9b on the sliding plate 9 in order to restrict the sliding of the sliding plate 9 at the positions shown in FIGS. It can be configured by fixing the stop portion 2c (FIGS. 3 and 7) to which the 9b stops, to the slide groove 2b.
[0027]
Between the bearing portions 2 a and 2 a of the base portion 2, a jammer plate 2 d is horizontally mounted. The jammer plate 2d is set to a width that does not block the tape introduction path K, and is provided on the rear side in the pressing direction (P direction in FIG. 9) with respect to the slide grooves 2b and 2b.
[0028]
Further, a first pin 2e horizontally mounted in the slide grooves 2b and 2b is fixed between the bearing portions 2a and 2a. The first pin 2e is provided at a position where a gap slightly wider than the thickness of the adhesive tape T is formed between the first pin 2e and the sliding plate 9 when the sliding plate 9 is in the locking position of FIG. Yes. Further, between the bearing portions 2a and 2a, a second pin 2f is horizontally mounted at a position near the elastic roller 6a, the slide groove 2b, and the tape introduction path K.
[0029]
Furthermore, a gap G extending in the jig sliding direction (X direction) from the vicinity of the second pin 2f along the sliding plate 9 is formed in the base 2 (FIGS. 8 and 9).
[0030]
Next, the usage method of the adhesive tape sticking jig | tool 1 which has the said structure is demonstrated. Here, the adhesive tape T used is almost the same as the conventional one, but as shown in FIG. 13, the release paper TL is provided with a cut C at a position away from the tip by a predetermined distance. Is different from the conventional one. In the following description, the “support” will be described as including the adhesive layer TS and the protective layer TP as one body.
[0031]
First, the sliding plate 9 is pulled out from the base 2 as shown in FIG. Then, the adhesive tape T is inserted through the tape guide path K with the protective layer TP on the elastic roller 6a side, as shown by the one-dot chain line in FIG. At this time, the adhesive tape T is inserted until the position of the break C in the release paper TL reaches the vicinity of the position of the slide groove 2b.

Next, as shown in FIG. 10, the sliding plate 9 is pushed in along the slide groove 2b, and the sliding plate 9 is moved to a predetermined position (position shown in FIG. 10) by the first locking means (not shown). Lock.
[0033]
In this state, the pressing lever 3 is resisted against the elastic force of the torsion spring 8, the pressing roller 7 is separated from the groove-type guide 4, and the tip of the adhesive tape T is attached to a predetermined position on the inner surface of the door sash frame F. 11 (see FIG. 11), the reinforcing bulge portion F2 of the door sash frame F is fitted between the side guide rollers 4a... 4a of the grooved guide 4 (see FIG. 8), and the pressing lever 3 is twisted and elastic of the spring 8 The reinforcing bulge F2 of the door sash frame F is clamped by the pressing roller 7 and the bottom guide rollers 5 ... 5 (FIGS. 8 and 11).
[0034]
Thus, the adhesive tape attaching jig 1 is self-held on the door sash frame F, and the adhesive tape attaching jig 1 is door sashed in the jig sliding direction (X direction) as shown in FIGS. Slide along the frame F.
[0035]
As the adhesive tape sticking jig 1 slides, the adhesive tape T is sent to the adhesive tape sticking jig 1 and bent by 90 degrees by the second pin 2f, but is formed of paper, plastic film or the like. The release paper TL is peeled off from the support TB (including the protective layer TP and the adhesive layer TS as a unit) at the cut C without being bent by the second pin 2f, and travels straight through the release paper guide path. It passes through the gap | interval G which comprises, and it sends out out of the adhesive tape sticking jig | tool 1. FIG. Thus, an adhesive tape guide means for separating the release tape TL from the adhesive tape T and guiding it to the elastic roller 6a can be configured. The release paper TL ′ in the part before the cut C can be peeled off after the adhesive tape T in the part after the cut C is attached to the door sash frame F.
[0036]
In addition, since the adhesive tape T may be extended during application when an extra tension is applied to the adhesive tape, the friction between the sliding plate 9 and the adhesive tape T does not occur as much as possible. For example, the contact surface of the sliding plate 9 with the adhesive tape T is formed of a material having a small friction coefficient, or the tip corresponding to the contact surface of the sliding plate 9 as shown in a sectional view in FIG. It is desirable that the roller 10 is rotatably attached to and supported by the portion.
[0037]
Next, the effect of the adhesive tape sticking jig | tool 1 which has the said structure is demonstrated.
[0038]
The adhesive tape attaching jig 1 holds the reinforcing bulge portion F2 of the door sash frame F by the bottom guide rollers 5 ... 5 and the pressing roller 7 and holds the side guide rollers 4a ... 4a. Thus, the outer surface of the frame body portion F1 of the door sash frame F and the reinforcing bulge portion F2 are guided. Therefore, the adhesive tape sticking jig 1 can be positioned in two directions (Y and Z directions in FIG. 11 and vice versa) perpendicular to each other with respect to the longitudinal direction of the door sash frame F. Since the attitude | position of the tape sticking jig | tool 1 can be stabilized, there is no position shift of the adhesive tape T. FIG.
[0039]
In addition, when the adhesive tape application jig 1 is slid with respect to the door sash frame F, the adhesive tape is applied by rolling with rollers (4a ... 4a, 5 ... 5, 6a, 7). The jig 1 can be slid at high speed.
[0040]
Furthermore, since the pressing lever 3 is elastically biased by the torsion spring 8, when the door sash frame F is clamped, a required pressing force can be applied to the elastic roller 6a constituting the pressing portion. By using the elastic roller 6a, a substantially uniform pressing force can be applied to the surface of the door sash frame F even if the surface of the door sash frame F is slightly curved in the width direction. Unevenness of attaching the tape T can be eliminated. By using one pressing roller 7 of the pressing lever 3, even if there is a portion that is slightly narrowed in the curved portion of the door sash frame F, it can be surely followed without being displaced. Further, due to the principle of the lever of the pressing lever 3, the operation of sandwiching the adhesive tape attaching jig 1 with respect to the door sash frame F can be easily performed with one hand.
[0041]
Moreover, the adhesive tape sticking jig | tool 1 isolate | separates the release paper TL from the adhesive tape T reliably and continuously by the said adhesive tape guide means, and sticks the adhesive tape T to the door sash frame F. be able to. Further, for such separation, the adhesive tape T can be inserted into the tape introduction path K, and the sliding plate 9 can be moved by a simple operation, which is excellent in workability. Furthermore, by providing the gap G that forms the release paper guide path, the release paper TL is more effectively separated.
[0042]
Next, another preferred embodiment of the adhesive tape sticking jig according to the present invention will be described with reference to FIGS. The embodiment described below is different only in that it does not include the jammer plate 2d and the first pin 2e in the above-described embodiment, and the other components are the same, so the same reference numerals are given. Detailed description will be omitted.
[0043]
The second pin 2f shown in FIG. 18 is in contact with the adhesive tape body (TB, TS, TP) side of the adhesive tape T and adheres while peeling off the release paper TL of the adhesive tape T passing therethrough. A contact portion that changes the tape body (TB, TS, TP) in a direction toward the pressing surface of the pressing portion 6 is configured, and the adhesive tape guide portion 9 'is located upstream of the contact portion in the adhesive tape running direction. Then, the adhesive tape T is brought into contact with the release paper TL and the direction is determined toward the contact portion. These contact portions (second pin 2f) and the adhesive tape guide portion 9 'constitute tape running direction changing means for changing the supply path of the adhesive tape T to reach the pressing surface.
[0044]
The contact portion can be configured by a portion opposite to the pressing surface of the elastic roller 6a without using the second pin 2f, but by forming the contact portion with the second pin 2f, the release paper TL There is an advantage that the peeling position can be accurately controlled.
[0045]
In the adhesive tape sticking jig 1 ′ having such a configuration, as shown in FIG. 18, the adhesive tape T runs substantially without running resistance on the upstream side of the adhesive tape guide portion 9 ′. Therefore, the pressure-sensitive adhesive tape main body after the release paper is peeled off is not tensioned to extend the pressure-sensitive adhesive tape main body.
[0046]
