Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for removing a window material for a vehicle, which enables the window material to be easily removed from a window opening of the vehicle.

[0002]

2. Description of the Related Art A transparent glass plate, which is a window material, is attached to a window opening of a vehicle body of an automobile or the like. The glass plate is adhered to the edge of the window opening via an adhesive, or is adhered via a resin frame member and an adhesive.

As an example, FIG. 14 shows a cross-sectional view of the adhesive structure of the upper portion of the rear glass of an automobile. The upper side of the glass plate 12 is strongly adhered by the adhesive 11 to the inside surface 12b of the glass plate 12 at the peripheral edge of the window opening 15 of the body panel (outer panel) 10a, to the mounting flange 16 arranged inside the body panel 10a from the surface of the body panel 10a. Has been done. The mounting flange 16 and the body panel 10a are connected by the opening side wall 15a. Mounting flange 16
Extend along the periphery of the window opening 15 of the body panel 10a.

Conventionally, the glass plate has been removed from the vehicle body as follows. First, a thread-like cutting means such as a piano wire (having a diameter of about 0.5 mm) is penetrated through the adhesive 11 between the glass plate 12 and the mounting flange 16 shown in FIG. 14 inside and outside the vehicle (left-right direction in the figure). Let Next, one operator holds the inside end of the cutting means and the outside end of the cutting means by another worker. Then, in cooperation with the two workers, the cutting means is circulated along the peripheral edge of the glass plate 12 while reciprocating the cutting means in and out of the vehicle to cut the adhesive 11. Thus, the glass plate 12 was removed from the vehicle body. However, such work is extremely complicated, burdens the operator, and takes a long time.

The outer peripheral shape of the glass plate 12 and the shapes of the mounting flange 16 and the body panel 10a differ depending on the vehicle model. When the adhesive 11 is manually cut as described above, two workers appropriately adjust the handling of the cutting means based on their skill to prevent the cutting means from cutting into the mounting flange 16, for example. Meanwhile, the cutting work is performed. However, it was extremely difficult to automate this cutting work.

In Japanese Unexamined Patent Publication No. 8-1598, two jigs having a suction cup and a winding roller are fixed to the glass plate at a substantially central position, and both ends of a wire inserted through an adhesive are wound. A technique is disclosed in which a wire is looped by being fixed to a take-up roller, and the wire is taken up by a take-up roller to cut the adhesive with the wire. In Japanese Unexamined Patent Publication No. 2000-289582, a guide is provided in which an outer side portion and an inner side portion of a wire inserted through an adhesive are arranged substantially parallel to each other, and the inner side portion of the wire is fixed to an inner corner portion of a glass plate. A technique is disclosed in which an adhesive is cut by moving a wire along a roller by indexing.

[0007]

Recently, in consideration of recycling, it has been required to easily and quickly remove a glass plate for an automobile window from a vehicle body. In the method disclosed in Japanese Patent Laid-Open No. 8-1598, it is complicated and time-consuming to set the wire so as to form a loop. To prevent the wire from breaking,
Prior to setting the wire, a pretreatment is required to remove the clip that holds the molding on the periphery of the glass plate to the mounting flange. Further, the length of the wire, which is a consumable item, is inevitably long. Also, after completing the removal of the glass plate of one car and before starting the removal of the glass plate of the other car, it is necessary to rewind the wire wound on the take-up roller. Requires.
This method is not suitable for the recycling process that requires removal of the glass sheet in a short time. JP 2000
In the method disclosed in Japanese Patent No. 289582, it is complicated to fix the guide rollers to the four corners of the glass plate, and the mechanism becomes complicated. This method is also not suitable for the recycling process. An object of the present invention is to provide a method of removing a window material for a vehicle, which enables easy and quick removal of the window material from a window opening portion of the vehicle.

[0008]

According to the present invention, a linear cutting means is penetrated through the adhesive at a predetermined position on the periphery of a window member adhered to the mounting flange of the vehicle body with the adhesive, and the cutting means is provided with the above-mentioned cutting means. A method for removing a window material for a vehicle, in which the adhesive is cut while moving along the peripheral edge of the window material to remove the window material from the vehicle body. And the vehicle outside tension holding point is set, and the position of the vehicle inside tension holding point is set such that the projected position on the window material spreads to the vicinity of both sides between the upper side and the lower side of the window material. Set it to the center position,
When cutting the adhesive on the upper side with respect to the central region of the window material, the tension holding point inside the vehicle is generally positioned at a first position near one side of the window material, and On the other hand, when cutting the lower adhesive, the vehicle interior tension holding point is generally positioned at a second position near the other side of the window material, and the adhesive is cut by the cutting means. A method for removing a vehicle window material is provided.

In the present invention, the tension holding point on the inside of the vehicle and the tension holding point on the outside of the vehicle refer to points on the cutting means, respectively, and apply a force to the cutting means in a direction substantially parallel to the surface direction of the window member. Refers to. The window material may be a glass plate or a resin plate.

According to the above method for removing a window material for a vehicle, the cutting means bites into the mounting flange by arranging the tension holding point inside the vehicle at a predetermined position near the inside surface of the window material. However, it can be prevented significantly. By connecting the vehicle inner side tension holding point and / or the vehicle outer side tension holding point to an appropriate drive portion, it becomes possible to automate the adhesive cutting operation. When cutting the adhesive on the upper side with respect to the central region of the window material, it is better to start the cutting from a position on the opposite side of the side where the first position of the vehicle interior tension holding point is located. When cutting the adhesive on the lower side with respect to the central region, it is preferable to start the cutting from a position on the side opposite to the side where the second position of the vehicle interior tension holding point is located.

In the present invention, it is preferable to appropriately move the in-vehicle tension holding point between the first position and the second position when necessary while cutting the adhesive. By doing this,
It is possible to more reliably prevent the cutting means from cutting into the mounting flange by cutting. Moreover, the following effects are also exhibited. That is, when the angle formed by the tangent line in the circumferential direction of the window material at the point where the adhesive is about to be cut and the line connecting that point and the inside tension holding point becomes an acute angle, the inside tension holding point and outside tension The tension acting between the holding point and the holding point can be effectively used as a force for cutting the adhesive. Therefore, when the formed angle becomes an obtuse angle, by appropriately moving the vehicle interior tension holding point so that the formed angle becomes an acute angle, the work of cutting the adhesive can be performed more quickly. Further, in the present invention, the cutting means,
Sliding back and forth with respect to the place where the adhesive is to be cut is preferable. For example, by connecting the inner-side tension holding point to the rotary motion drive unit (crank motion drive unit) or the reciprocating motion drive unit, the adhesive can be easily cut, and the time required for the cutting operation can be greatly reduced. Further, in the present invention, it is preferable to use a wire having a diameter of 1 to 4 mm as the cutting means. By doing this, the wire is thick and strong, so the wire does not cut into the mounting flange.
It can be prevented more reliably. In addition, since the clip can be repelled by the wire, a pretreatment for removing the clip before setting the wire is unnecessary. Further, in the present invention, the position of the vehicle interior tension holding point is set to a position where the angle formed by the line connecting the vehicle interior tension holding point and the end of the mounting flange and the extension line of the mounting flange is 45 ° or less. Is preferred. By doing so, it is possible to more reliably prevent the cutting means from cutting into the mounting flange by cutting.

[0012]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described in detail below with reference to the drawings. FIG. 1 shows a state in which a rear window of an automobile is viewed from the outside of the vehicle as an example of the window material (glass plate). The window member 12 is formed into a curved plate that is trapezoidal in plan view and that is convex toward the outside of the vehicle. The upper side of the window member 12 is curved so that its central portion is convex toward the lower side. The upper side of the window material refers to the side along the roof of the automobile, and the side edge of the window material refers to the side along the pillars of the automobile. The window member 12 is adhered to the mounting flange of the body panel via an adhesive as in the example shown in FIG.

As shown in FIG. 1, at a predetermined point (cutting start point) P1 on the periphery of the window member 12, a wire 20 as a linear cutting means is penetrated through the adhesive. The end of the wire 20 on the vehicle interior side is connected to the vicinity of the peripheral edge of the rotating body 22 as the vehicle interior tension holding point 20a. The rotating body 22 is arranged inside the vehicle at the center of the window member 12. The rotating body 22 is
It is connected to a motor (not shown) to form a rotary motion drive unit. A point outside the vehicle of the wire 20 is defined as a vehicle outside tension holding point 20b. The vehicle outside tension holding point 20b may be moved on the wire 20 by, for example, re-grip by an operator. The outside tension holding point 20b may be gripped by an operator or may be gripped by an automatic means such as a robot arm. As will be described later, the wire 20
When the outer side portion of the vehicle is hooked on a guide member such as a hook and pulled before the guide member, the portion of the wire 20 that engages with the guide member functions as the outer side tension holding point 20b. The vehicle outer side tension holding point 20b is made to circulate along the peripheral edge of the window member 12.

At the cutting start point P1, the outside tension holding point 20b is set in a direction along the tangential direction of the window member 12 (tangential direction of the circumferential direction) and in a direction in which the peripheral edge of the window member 12 is rotated clockwise in the drawing. While pulling, the rotating body 22 is rotated in the clockwise direction in the drawing. At this time, the inside tension holding point 20a
However, due to the rotating crank motion, it repeatedly approaches and separates from the adhesive cutting point. As a result, the wire 20 reciprocates in and out of the vehicle, and the wire 20 slides back and forth with respect to the adhesive cutting point. The wire 20 reciprocally slides at the adhesive cutting point and the vehicle-side tension holding point 20b is pulled, so that the adhesive that bonds the window member 12 and the body panel to each other in the clockwise direction in the figure. It will be cut in sequence. Window material 1
If there are clips or spacers on the periphery of 2,
These clips and spacers can also be repelled by the wire 20. The wire 20 has a diameter of 1 to 4
mm, and more preferably a diameter of 1.5 to 3.5 mm. As the wire 20 having such a diameter,
Although a straight piano wire may be used, it is preferable to use a twisted wire having high strength.

Next, the position of the vehicle inner side tension holding point 20a will be described with reference to FIG. 2 which is a sectional view taken along line II-II in FIG. As shown in FIG. 2, the window member 12 has an inner side surface 12b at the upper side thereof bonded to the mounting flange 16 of the body panel 10a via an adhesive 11. Similarly, the lower side of the window member 12 is also bonded to the mounting flange 16. The inner side tension holding point 20a is the inner side tension holding point 20a.
Angle a formed between a line connecting a and the end of the mounting flange 16 (end on the inner peripheral side with respect to the window opening) and an extension line of the mounting flange 16 (extended line to the inner peripheral side of the window opening) But 4
It is arranged close to the window member 12 so as to be 5 ° or less. Not only on the side and the upper side, but also when the wire 20 reaches the lower side of the window member 12, the tension holding point 2 on the inside of the vehicle is maintained.
0a and the line connecting the ends of the mounting flange 16 and the extension of the mounting flange 16 form an angle θ1 of 45 ° or less. By doing so, the wire 20 is attached to the mounting flange 16
It prevents you from biting into. As shown by the chain double-dashed line in the figure, when the vehicle interior tension holding point 20 a is located far from the window member 12, the wire 20 easily bites into the mounting flange 16.

Next, with reference to FIG. 3, an angle θ2 formed by a tangent line in the circumferential direction at a predetermined point on the peripheral edge of the window member 12 and a line connecting the point and the in-vehicle tension holding point 20a will be described. In order to simplify the explanation, the tension holding point 20 on the inner side of the vehicle
It is assumed that a is fixed near the center of the window material 12. In FIG. 3, θ2 at the cutting start point P1 is a right angle. When the vehicle outer side tension holding point 20b is rotated in the clockwise direction in the figure along the peripheral edge of the window member 12, θ2 becomes an obtuse angle. However, when going into the section B beyond the section A in the circumferential direction, θ2 becomes an acute angle (0 ° ≦ θ2 ≦ 90 °). When the vehicle outer side tension holding point 20b is rotated once, in the sections A, C, E, and G, θ2 becomes an obtuse angle, and the sections B, D, and
In F and H, θ2 becomes an acute angle. As a result of an experiment conducted by the present inventors, when θ2 becomes an acute angle, the vehicle interior tension holding point 20a
It was found that the tension acting between the vehicle outside tension holding point 20b and the vehicle outside tension holding point 20b can be effectively utilized as a force for cutting the adhesive, and the adhesive can be cut smoothly and quickly.

Therefore, the present inventors have conceived to appropriately move the vehicle interior tension holding point 20a so that θ2 becomes an acute angle in most of the entire circumference of the window member 12 (for example, 70% or more). . For example, as shown in FIG. 4, when the vehicle inner side tension holding point 20a is moved so that the projection locus on the window member 12 becomes elliptic as indicated by reference numerals I1 to I12 in the figure, the section shown in the figure At O, only θ2 becomes an obtuse angle, and θ2 can be made an acute angle in other sections. When the vehicle interior tension holding point 20a is located at a point indicated by reference numeral I4 in the drawing (when the adhesive cutting point is located near the upper corner of the window material 12), the wire 20 is attached to the periphery of the window opening. It was found that the wire was likely to bite into the mounting flange in an attempt to project further outward.

Based on the above consideration, a first example of the method for removing a vehicle window member according to the present invention will be described with reference to FIG.
In this example, the rotor 22 that holds the inner-tension holding point 20a is placed inside the window member 12 in the horizontal direction (the window member 12).
It is possible to move as shown by an arrow X in the drawing along a direction (connecting one side and the other side). here,
The rotating body 22 is slidably attached to a rail 23 that extends horizontally in the middle of the height of the window member (in the middle between the upper side and the lower side). The rotating body 22 can be automatically slid in the horizontal direction by a reciprocating motion drive unit such as an air cylinder. It is preferable that the rotating body 22 be as close as possible to the side of the window opening. In this example, the position of the tension maintaining point 20a on the vehicle interior is set near the inner surface of the window material 12 as shown in FIG. 2, and the projection position on the window material 12 is the window material 1.
The position is located between the upper side and the lower side of the window 2 in the central region of the window material that extends to the vicinity of both sides. In addition, a plate-shaped guide member 25 is arranged near the upper corner of the peripheral edge of the window opening. The upper end of the guide member 25 is arranged on the vehicle outer surface of the mounting flange.

First, as shown by the solid line in FIG.
2 is arranged on the right side in the figure. Then, the cutting start point P1 is set on the left side of the drawing. The rotating body 22 is rotated to reciprocate the wire 20, and the outside tension holding point 20
The adhesive is sequentially cut by pulling b to orbit. When the adhesive cutting point reaches the area indicated by reference numeral P2 in the figure (near the upper corner), the wire 20 slides on the guide member 25 without cutting into the mounting flange. On the guide member 25,
The wire 20 makes line contact with the guide member 25. Then, when the cutting further progresses and the adhesive cutting point reaches the point shown by reference numeral P3 in the figure, the rotating body 22 is moved to the left side as shown by the chain double-dashed line in the figure. In this state, the rotating body 22 is rotated to reciprocate the wire 20, and
0b is further circulated, and the remaining adhesive on the entire circumference of the window member 12 is cut. That is, in this example, when cutting the adhesive on the upper side with respect to the central region of the window member 12, the tension holding point inside the vehicle is located at the first position near the side on the right side of the window member 12 in the figure, When the adhesive on the lower side with respect to the central region of the material 12 is cut, the tension holding point 20a on the inside of the vehicle is positioned at a second position near the side on the left side of the window material 12 in the drawing and the adhesive is applied by the wire 20. Disconnect. According to this example, in 70% or more of the entire circumference of the window member 12, the tangential line in the circumferential direction at a predetermined point on the peripheral edge of the window member 12, that point, and the vehicle interior tension holding point 20.
The angle formed by the line connecting a and a can be an acute angle.
Therefore, the adhesive can be cut smoothly and quickly.

Instead of the guide member 25 preventing the wire 20 from biting into the mounting flange, the following may be done. That is, when the adhesive cutting point reaches the area indicated by the symbol P2 in the drawing (near the upper corner), the rotating body 22 is temporarily moved to the left from the first position shown by the solid line in the drawing. The wire 20 may be prevented from cutting into the mounting flange. When the adhesive cutting point is separated from the vicinity of the upper corner of the window member 12, the rotating body 22 is returned to the first position. That is, while cutting the adhesive, the in-vehicle tension holding point 20a can be appropriately moved between the first position and the second position when necessary.

Next, a second example of the method for removing the vehicle window member will be described with reference to FIG. In this example, a plurality of pulleys (guide members) 24 that function as vehicle interior tension holding points are arranged inside the window member 12. Here, one pulley 24 is arranged near one side of the window member 12, and one pulley 24 is arranged near the other side of the window member 12. The pulley 24 is preferably located as close as possible to the side of the window opening. The distance between the outer circumference of the pulley 24 and the side of the window opening can be set to about 1 to 250 mm. The pulley 24 is arranged laterally so that its rotation axis extends in the thickness direction of the window material 12, and an adjusting mechanism is provided so that the rotation axis can be tilted according to the curve of the window material 12. It is preferable to keep. From the cutting start point P1 set on the left side in the figure, the wire 20 is wound around the pulley 24 on the right side in the clockwise direction in the figure, and then the pulley 24 on the left side.
In a clockwise direction in the figure, and then, via an appropriate guide member (here, a vertically oriented pulley) 24a,
It is connected to the rotating body 22 arranged in the vehicle. Also,
A plate-shaped guide member 25 was provided near the upper corner of the peripheral edge of the window opening, as in the first example.

The rotating body 22 is rotated to reciprocate the wire 20 and the outside tension holding point 20b is pulled to orbit, thereby sequentially cutting the adhesive. In the initial stage of cutting, the portion of the wire 20 that engages with the right pulley 24 functions as a vehicle interior tension holding point. The wire 20 is removed from the pulley 24 on the right side as the cutting progresses and the adhesive cutting point sequentially moves to the position indicated by reference numeral P2 and the position indicated by P3 in the drawing.
Then, when the adhesive cutting point reaches the area indicated by reference sign P4, the wire 20 is completely removed from the pulley 24 on the right side. From this point, the portion of the wire 20 that engages with the pulley 24 on the left side functions as a vehicle interior tension holding point. In this state, the rotating body 22 is rotated to reciprocate the wire 20, and the outside tension holding point 20b is further circulated to cut off the remaining adhesive on the entire circumference of the window member 12. According to the present example, the tangential line in the circumferential direction at a predetermined point on the peripheral edge of the window member 12, the point, and the tension inside the vehicle are maintained in most of the entire circumference of the window member 12 with a simple configuration with a reduced number of drive parts. The angle formed by the line connecting the point 20a can be made acute, and the adhesive can be cut smoothly and quickly.

Next, a third example of the method for removing the vehicle window member will be described with reference to FIG. In this example, in addition to the configuration of the second example shown in FIG.
It is arranged so as to extend vertically in the center of the vehicle.
The window member 12 is formed as a curved plate that is convex toward the outside of the vehicle. The pulley 24 disposed near one side of the window member 12 and the pulley 24 disposed near the other side thereof are respectively
The rotation axis is set to be parallel to the thickness direction of the window material 12. Pulleys 24, 24 and guide member 28
Is arranged in the vicinity of the side surface of the window member 12 on the inside of the vehicle.
In accordance with the curved shape of 2, the guide member 28 has a pulley 24,
It is located outside the car from 24. From the cutting start point P1 set on the left side of the drawing, the wire 20 is brought into contact with the surface of the upper part of the guide member 28 on the side of the window member 12 and then wound around the pulley 24 on the right side in the clockwise direction in the drawing. Then, the surface of the lower part of the guide member 28 on the side of the window member 12 is contacted, and then the pulley 24 on the left side is hung in the clockwise direction in the drawing, and then an appropriate guide member (here, the vertical direction). The rotating body 22 disposed in the vehicle via
It is connected to the. By thus passing through the guide member 28, the wire 20 is brought as close as possible to the window member 12, and the wire 20 is prevented from coming off from the pulleys 24, 24.

The rotating body 22 is rotated to reciprocate the wire 20 and the outside tension holding point 20b is pulled to orbit, whereby the adhesive is sequentially cut. In the initial stage of cutting, the wire 20 contacts the upper surface of the guide member 28 and is guided to the vehicle interior tension holding point on the side opposite to the adhesive cutting point. The guide member 28 is the wire 20.
A force is applied to the window member 12 in a direction orthogonal to the surface direction of the window member 12. When the cutting progresses and the adhesive cutting point moves to a position indicated by reference numeral P2 in the drawing, the wire 20 is disengaged from the upper surface of the guide member 28. As the cutting progresses further, the wire 2
0 is disengaged from the pulley 24 on the right side in the figure, and the portion of the wire 20 that engages with the pulley 24 on the left side in the figure functions as a vehicle interior tension holding point. For a while, the wire 20
It contacts the lower surface of the guide member 28 and is guided to a tension holding point on the inside of the vehicle on the side opposite to the adhesive cutting point. In this example, since the wire 20 is wound around in accordance with the curve of the window member 12, the wire 20 is not caught by the mounting flange, and the adhesive can be cut smoothly. Further, by using the guide member 28, the wire 20 is reliably prevented from coming off the pulleys 24, 24.

Next, an example of a method for automating the work of pulling the vehicle outside tension holding point will be described with reference to FIG. Figure 8
As shown in FIG. 3, the wire 20 is hung around the pulley 24b installed above the outside of the vehicle, and the weight W is hung on the end of the wire 20 on the outside of the vehicle to exert a tension on the wire 20. The pulley 24b can be installed obliquely above the window material (rear window) 12, that is, in a direction perpendicular to the vehicle outer surface of the window material 12. In this state, as in the third example described above, if the vehicle interior tension holding point is circulated in the vehicle, the adhesive can be cut quickly and smoothly. The front window 32 and the side window 42 can be similarly removed.

In the example shown in FIG. 8, it is preferable that the tension holding point on the outside of the vehicle is made to circulate along the peripheral edge of the window member 12. For example, as shown in FIG. 9, a rail 30 for guiding the vehicle outer side tension holding point 20b so as to move along the peripheral edge of the window material may be installed in the diagonally upper vicinity of the window material 12 shown in FIG. it can. Instead of using the weight W shown in FIG. 8, the rail 30 may be configured by, for example, a rack, and the vehicle on which the pinion is mounted may have the vehicle outside tension holding point 20b. Further, the vehicle outside tension-holding point 20b may be provided on a moving body that mounts a motor and travels autonomously in the rail 30. The moving body may include a tension applying mechanism such as a wire winding mechanism or a balancer.

Instead of using rails, as shown in FIG. 10, guide members 31 such as hooks, which are arranged at intervals with each other according to the peripheral shape of the window material, may be used. here,
The wire 20 is wound around the hooks 31 arranged at the four corners corresponding to the four corners of the window material. As the cutting of the adhesive progresses, the hook 31 and the wire 20 are disengaged in the clockwise direction in the drawing.

Next, an example of the perforating means for inserting the cutting means into the adhesive will be described. The perforating means 35 shown in FIG. 11 (A) is composed of a cylindrical body having a sharp tip. With the tip of the perforation means 35 being penetrated by the adhesive, the wire 20 as the cutting means is inserted into the cylindrical body,
Can be penetrated inside and outside the vehicle. After that, the piercing means 35 can be removed and the cutting of the adhesive by the wire 20 can be started. By using this example, it is possible to easily and quickly penetrate the wire 20 into and out of the vehicle. Figure 11
The piercing means 45 shown in (B) has a sharp tip, and the tip thereof generates heat by energization or the like. Using this example, the adhesive can be partially melted to easily form a hole for penetrating the wire. FIG. 11 (A),
The perforating means 35 and 45 shown in (B) are suitable for perforating the adhesive on the lower side of the window material such as the rear glass.

The piercing means 55 shown in FIG. 12 (A) has an L-shaped tip, and the tip thereof generates heat when current is applied. If this example is used, as shown in FIG. 12B, the adhesive 11 can be perforated on any side of the window material 12 without interfering the perforation means 55 with the mounting flange 16.

The present invention is not limited to the above-described embodiment, but can be appropriately modified and improved.
In the example shown in FIGS. 6 and 7, the pulley 24 that provides the vehicle interior tension holding point has a rotation axis parallel to the thickness direction of the window member 12, but is not limited thereto. For example, as shown in FIG. 13, its rotation axis is parallel to the surface direction of the window material (longitudinal direction), and its rotation axis moves on the circumference as indicated by the chain double-dashed line in the figure. A pulley 24 so held may be used. For example, in the example shown in FIG. 7, a rod-shaped guide member 28 is provided inside the vehicle at the center of the window member 12.
However, a plurality of pulleys may be arranged inside the window member 12 in an appropriate shape such as an ellipse.
