Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a panel with a frame.

[0002]

2. Description of the Related Art A frame body mounted on a peripheral portion of a panel such as a windshield for a vehicle is usually extruded in a straight line with synthetic resin, rubber or the like, and the frame extruded into the straight line is formed. While being bent at each corner of the panel, the panel is fitted into the peripheral edge of the panel and bonded. However, in the case where the frame body is extruded in a straight line as described above, not only a lot of time and labor are required for the work of fitting the frame body to the peripheral portion of the panel and adhering it, but also the corner of the panel is required. There is a problem in that "wrinkles" and "lifting" occur in the frame in the portion and its vicinity, and the appearance and design are impaired.

In order to solve the trouble of mounting the frame on the peripheral portion of the panel and the problem of appearance design, for example, the one disclosed in Japanese Patent Laid-Open No. 63-15716 is known. In this case, after setting the panel in a pair of molds for injection molding and clamping both molds, a frame material such as resin or rubber is placed in the cavity at the peripheral edge of the panel in both molds. By injecting, a frame is formed on the peripheral edge of the panel.

[0004]

However, in injection molding, particularly when the panel becomes large, the cost of manufacturing the die becomes large and the cost becomes high. Further, when the panels are set in a pair of molds and the molds are clamped, the pressure due to the mold clamping of the molds may act on the panels, resulting in damage to the panels. Furthermore, the damaged panel damages the mold surface of the mold, which appears as uneven scratches on the surface of the frame, resulting in a defective product.

Further, in Japanese Patent Application Laid-Open No. 4-151225, in order to improve the mountability of the frame body, extrusion molding is performed while rotating the glass window (panel) with respect to the extrusion nozzle in a fixed state. A molding method is disclosed in which a resin molded product is attached to the outer peripheral edge. However, in the resin molded product molded by this method, there is a problem that a portion corresponding to the outer peripheral side in the corner portion, that is, the curved portion is collapsed due to an inward pulling force and the cross-sectional shape is deformed.
If such an inward fall occurs, a gap is generated during mounting, and as a result, the shield sealing function and the decoration function are impaired.

The inward fall of the corner portion is caused by the insufficient capacity of the material in the outer peripheral side portion of the resin molded product. For example, consider the case where the linear member on the right side of FIG. 12 is bent and formed to have a central angle θ and a radius of curvature r as shown on the left side of FIG. First, when the length of the linear member is L ₀ , the width is t, and the area is S ₁ , the area S ₀ after bending is

[Equation 1] Becomes here,

[Equation 2] Therefore, the area S ₁ before bending is

[Equation 3] Is represented. Therefore, when the difference between the area S ₀ after bending and the area S ₁ before bending is calculated,

[Equation 4] Becomes Therefore, at the corner, the above formula (4)
As a result, the capacity is insufficient for the volume obtained by multiplying the wall thickness.

In view of the above-mentioned conventional problems, the present invention makes it possible to easily and accurately fit the frame into the peripheral edge of the panel, and at the same time, at the corner of the panel or in the vicinity thereof. "Wrinkles" and "rises"
It is an object of the present invention to provide a method for manufacturing a panel with a frame, which can prevent the occurrence of the above and can achieve a good mounted state in both the straight portion and the corner portion.

[0008]

In order to solve the above-mentioned conventional problems, the first means of the present invention is to manufacture a panel with a frame body in which a frame body is attached to the peripheral edge of the panel. In the method of manufacturing a panel with a frame body, a part of the peripheral portion of the panel is inserted from the side opening portion into an extrusion molding port provided in a die device for extrusion molding, and the peripheral portion of the panel and the extrusion portion are inserted. A molding space corresponding to the cross-sectional shape of the frame is formed between the molding port and the panel while the frame material fed from the die device is extruded from the extrusion molding port through the molding space. A die device is relatively moved along the peripheral portion of the panel, and a frame body connected to the peripheral portion of the panel is extruded and formed while joining and integrating the frame body to the peripheral portion of the panel. Form a frame along the corner In this case, the movable die is relatively moved with respect to the fixed die provided in the die device so that the extrusion molding is performed while expanding the opening shape of the extrusion molding port. ing.

A second means according to the present invention is the first means, wherein the movable die in the die device is moved in synchronization with the relative movement between the panel and the die device. ing.

[0010]

According to each of the above means, while the frame material fed from the material feeding path of the die device is pushed out from the extrusion molding port through the molding space, the panel and the die device are separated from each other by the peripheral portion of the panel. By being relatively moved along the frame, the frame-equipped panel in which the frame is integrally joined to the peripheral portion of the panel is easily manufactured. Further, at this time, an inward pulling force is generated in the frame due to the bending at the corner portion, but in the means having the above configuration, the portion bulging in the outer peripheral direction of the corner corresponds to the corner portion to which a large pulling force is applied. Since the thick portion is formed, the bulged thick portion of the corner portion is stretched according to the magnitude of the pulling force. As a result, the tensile stress is completely absorbed, and a frame body having a regular cross-sectional shape is formed without causing the corner mounting portion to collapse.

[0011]

Embodiments of the present invention will now be described in detail with reference to the drawings. First, an example of a panel with a frame formed by the present invention will be described with reference to FIGS. The illustrated example illustrates the case where the framed panel is a windshield with a molding for the front of the vehicle.

As shown in FIG. 1, which is a perspective view of a vehicle, a window glass 2 with a molding, which is mounted in a window opening of a vehicle body panel 1, is formed into a curved surface in consideration of design and aerodynamic characteristics. It is composed of a window glass 3 serving as a panel and a molding 4 serving as a frame integrally joined to the peripheral edge of the window glass 3. The edge surface and both front and back surfaces of the peripheral edge portion of the window glass 3 are subjected to a primer treatment, and then a resin adhesive is applied to the primer treatment portion as described later.

A molding 4 as a frame is joined to and integrated with the peripheral portion of the window glass 3 at the portion where the adhesive is applied. Molding 4
Is made of synthetic resin, rubber or the like, is continuous along the peripheral edge of the window glass 3 and is extruded onto the peripheral edge of the window glass 3 and is simultaneously joined by the adhesive. The molding 4 has a frame shape along the peripheral edge of the window glass 3, and the cross-sectional shape in the direction orthogonal to the longitudinal direction is uniform along the longitudinal direction. That is, the wind molding 4 is mounted in the gap between the upper edge of the windshield 3 and the roof panel and the gap between the side edges of the windshield 3 and the pillar panel. It also has a side molding 4C and a corner molding 4B as a curved portion that connects the upper molding 4A and the side molding 4C in a curved shape.

Further, as shown in FIGS. 2 and 3,
The window molding 4 has a leg portion 5 inserted in a gap between the peripheral edge portion of the window glass 3 and the vehicle body panel 1, and a decorative portion that covers the space between the window glass 3 and the vehicle body panel from the outside of the vehicle. 6 is provided at the vehicle-inside end (upper end in the figure) of the leg portion 5. The decorative section 6 and the leg section 5 make the cross-section orthogonal to the longitudinal direction substantially T-shaped.
It is shaped like a letter. Further, a supporting piece 7 for supporting the lower part of the window glass 3 is provided at the vehicle-inside end (lower end in the figure) of the leg portion 5 over the entire length, and between the supporting piece 7 and the decorative portion 6, a window is provided. A glass fitting support groove for receiving the glass 3 is defined by a U-shaped cross section that is uniform over the entire length.

Further, the decorative portion 6 has a glass-side decorative portion 6a and a panel-side decorative portion 6b which extend from the vehicle outer end of the leg portion 5 toward the window glass 3 side and the vehicle body panel 1 side. The respective parts 5, 6, 7 described above are set to have a uniform thickness and shape over the entire length of the molding.

In the window glass 2 with a molding configured as described above, the molding 4 is
Because it is continuous along the peripheral edge of the windshield 3,
It is excellent in design. Further, since the molding 4 is extruded onto the peripheral edge of the window glass 3 and is bonded to the peripheral edge of the glass 3 at the same time by an adhesive, the molding 4 is formed separately from the window glass 3. It is possible to eliminate the trouble of fitting by fitting the peripheral portion of the wind glass. Further, it is possible to eliminate the occurrence of "wrinkles" and "lifting" in the molding 4 at the corners of the windshield 3 and in the vicinity thereof, and it is possible to improve the appearance design.

The boom 80 is tilted in the vertical direction with the pin 81 as a fulcrum.

A panel suction unit 86 for detachably sucking the window glass 3 is attached to a mounting member 85 fixed to the tip of the boom 80, and a drive shaft using a tilting motor 89 as a drive source in a unit body 87 thereof. It is mounted so that it can be tilted around. On the lower surface of the unit main body 87, a rotation shaft driven by the rotation motor 91 is projected downward, and four support arms 93 in a cross shape are attached to the lower end of the rotation shaft. Further, a suction cup 94 that detachably adsorbs the window glass 3 is attached to the lower surface of the tip of each support arm 93.

The panel take-out device 95 for taking out the window glass 2 with molding, in which the molding 4 is extruded on the peripheral edge of the window glass 3 by the die device 11, is taken out from the panel holding device 60.

Has the same structure as the panel loading device 64, and in FIG. 4, the same reference numerals are given to the main members and parts, and the description thereof will be omitted.

In the panel supply receiving rack device 96 disposed on the side of the panel loading device 64, a pair of left and right support frames 100 is provided on the upper surface of a pallet base 97 that is movably installed on the floor. A plurality of pairs of panel receiving arms 101 are vertically erected on the front side surfaces of both support frames 100 so as to project upward. Each pair of panel receiving arms 101 is operated by an operating device (not shown) in a panel receiving position having a horizontal shape and a standby position having a vertical shape.
Then, the window glass 3 is placed in a stacked manner from the panel receiving arm 101 paired at the lowest stage to the panel receiving arm 101 at the upper stage in sequence.

The panel unloading shelf device 103 for stacking the window glass 2 with molding taken out from the panel holding device 60 by the panel unloading device 95 is similar to the panel supply shelf device 96. 4, and the description thereof will be omitted.

Next, the operation of the manufacturing apparatus of this embodiment configured as described above and the manufacturing method will be described. (Pretreatment Step) The window glass 3 is preliminarily subjected to a primer treatment on its peripheral edge and both front and back surfaces, and then a resin adhesive is applied to the primer treated portion. The window glass 3 which has been pretreated as described above is sequentially placed in a stacked manner on the panel receiving arms 101 forming each pair of the panel supply receiving rack devices 96. Then, the panel supply tray device 96 is moved to the panel supply device.

(Panel loading process) When the panel supply receiving rack device 96 is moved to the panel supply position, the panel loading device 64 is operated. Then, when the boom 80 is directed to the panel supply / receiving shelf device 96 by the turning of the swivel base 67, the boom 80 is placed on the uppermost layer of the panel supply / receiving shelf device 96 by the advancing / retreating motor 83 and the lifting / lowering motor 84. Is tilted forward and downward. At this time, the arm 93 is tilted in the opposite direction to the boom 80 by the tilting motor 89 of the panel suction unit 86 at the tip of the boom 80.
Is kept horizontal.

When the suction cups 94 of the panel suction unit 86 come into contact with the upper surface of the uppermost window glass 3 due to the forward and downward tilting of the boom 80, the suction cups 94 are made to have a negative pressure. Then, the wind glass 3 is adsorbed by each suction cup 94. When the window glass 3 is sucked by each suction cup 94, the boom 80 is tilted backward and tilted upward while the arm 93 of the panel suction unit 86 is kept horizontal. As a result, the windshield 3 is hung horizontally.

After that, the boom 80 is turned toward the panel holding device 60, and is also advanced and tilted downward toward the holding arm 62 of the panel holding device 60. At this time, the window glass 3 sucked by the panel suction unit 86 is oriented in a predetermined direction with respect to the holding arm 62 of the panel holding device 60. In this embodiment, the lower edge of the peripheral edge of the window glass 3 faces the die device 11. The rotation motor 91 of the panel suction unit 86 is rotated so that The window glass 3 is the holding arm 6 of the panel holding device 60.
It is placed on the suction cup 63 arranged on the upper part 2. The slide table 26 of the moving device 24 is retracted to the rear position in advance.

When the window glass 3 is placed on each of the suction cups 63 of the panel holding device 60, each of the suction cups 63 has a negative pressure, while each of the suction cups 94 of the panel loading device 64 has an atmospheric pressure. Will be returned. Then, the window glass 3 is adsorbed to each suction cup 63 of the panel holding device 60, and the loading of the window glass 3 into the panel holding device 60 is completed here. Then, the panel loading device 60
Goes to receive the next window panel 3 from the panel supply receiving rack device 96, and is stopped in the standby state shown in FIG.

(Extrusion Molding Step) The window glass 3 sucked by each suction cup 63 of the panel holding device 60.
If the glass surface is a curved surface, the panel holding device together with the tilting base 57 is placed so that the lower edge portion of the peripheral edge of the window glass 3 on the side facing the side opening of the die device 11 becomes horizontal. The holding arm 62 of 60 and the window glass 3 are tilted. Further, the moving device 24 is adjusted up and down so that the lower edge of the peripheral edge of the window glass 3 is at the height position corresponding to the side opening of the die device 11.

Here, the slide table 26 is moved forward,
A substantially central portion of the lower edge portion of the window glass 3 held by the panel holding device 60 is inserted into the extrusion molding opening from the side opening portion of the die device 11 by a certain amount. At this time, the second die 132 of the die device 11 is set at the position shown in FIGS. 5 and 6, and the extrusion molding port is maintained at a normal port area. As described above, the window glass 3 is inserted into the extrusion molding port, so that a molding space corresponding to the cross-sectional shape of the molding 4 is formed between the peripheral edge portion of the window glass 3 and the inner peripheral wall of the extrusion molding port. It When this molding space is constructed, the die device 11
The molding material P is supplied to the material feeding passage of No. 3, and the material P is extruded from the extrusion molding port through the molding space.

From the extrusion molding port, the molding material P
Is ejected, the first and second swiveling arms 36, 41
Are each swung in a predetermined direction, and the lower edge of the peripheral edge of the window glass 3 is moved at a controlled same speed. As a result, as shown in FIGS. 9 and 10, the molding 4 is sequentially extruded from the central portion of the lower edge of the peripheral edge of the window glass 3 toward the first corner portion.

Then, as shown in FIG. 10, when the first corner portion of the peripheral edge of the window glass 3 reaches the position of the extrusion molding port of the die device 11, the first and second swiveling arms 36, 41 are swung. At the same time, the turntable 48 is rotated and the die device 11 is relatively moved along the rounded surface of the first corner portion of the window glass 3. Furthermore, since the tilting table 57 is tilted in accordance with the curvature of the glass surface at the first corner portion, the first corner portion of the window glass 3 is kept horizontal with respect to the extrusion molding port of the die device 11.

At this corner, the die unit 11
The second die 132 is moved to the position shown in FIG. 7 and FIG. 8 to perform extrusion, and the outer peripheral portion of the molding is bulged outward to be thickened and the corner molding 4B is extruded. Molded. However, when the corner molding 4B is actually joined to the window glass 3, an inward pulling force due to the bending is generated in the frame body, and the bulging thick-walled portion of the corner portion is generated depending on the magnitude of the pulling force. Is stretched. Therefore, the tensile stress is completely absorbed, and the corner molding 4B having the same cross-sectional shape as the other portions is formed without causing the corner portion to collapse. In this case, since the movement of the second die 132 is controlled so as to be synchronized with the relative movement between the window glass 3 and the die device, the corner molding 4B accurately corresponds to the corner portion of the window glass 3. It is supposed to be molded. Further, the extrusion amount of the molding material P at this time is adjusted as the extrusion molding port is enlarged or reduced by the movement of the second die 132.

When the first corner portion of the window glass 3 passes through the extrusion port of the die device 11 and the right side edge of the peripheral edge of the window glass 3 reaches the extrusion port, as shown in FIG. The second die 132 of the die device 11
Is again moved to the position shown in FIGS. 5 and 6 and extrusion is performed. Then, the tilting table 57 is tilted corresponding to the curvature of the right edge portion of the peripheral edge of the window glass 3, and the right edge of the peripheral edge of the window glass 3 is kept horizontal with respect to the extrusion port, while Two swivel arms 36 and 41
The right edge of the peripheral edge of the window glass 3 is moved by.
Then, the side molding 4C of the molding 4 is extruded on the right side edge of the window glass 3.

The peripheral portion of the window glass 3 held by the panel holding device 60 in this way is moved by the moving device 2.
While being kept in a horizontal state by means of 4, it is always inserted into the extrusion molding port of the die device 11 at a constant insertion depth and moved at a controlled predetermined speed. Then, at this time, the second die 132 provided in the die device 11 is moved at a portion corresponding to the corner to perform extrusion molding while enlarging the extrusion molding port. As a result, the molding 4 having a uniform cross-sectional shape over the entire length is extruded on the peripheral edge of the window glass 3, and at the same time, the adhesive applied to the peripheral edge of the window glass 3 is applied to the peripheral edge of the window glass 3. The molding 4 is integrally bonded. When the entire length of the molding 4 is extruded along the peripheral portion of the window glass 3, the supply of the molding material P to the material supply path of the die device 11 is temporarily cut off.

(Preliminary Step) When the supply of the molding material is cut off, the slide table 26 is retracted to its original position. Then, the window glass 2 with molding is removed from the side opening of the extrusion molding port.
Thereafter, the window glass 2 with molding is placed on the pair of panel receiving arms 101 of the panel unloading receiving rack device 103 by the panel take-out device 95.

As described above, in the pretreatment process, the window glass 3 sequentially placed on the pair of panel receiving arms 101 of the panel supply / receiving shelf device 96 in a laminated manner.
Becomes the window glass 2 with molding in the extrusion molding process after the panel charging process. And the window glass 2 with molding goes through the take-out process,
The panel unloading shelf device 103 is sequentially stacked in a stacked manner from the lowermost panel receiving arm 101 to the upper panel receiving arm 101. And the panel carrying-out shelf device 103
When the window panel 2 with molding is placed on the uppermost panel receiving arm 101, the window panel 2 with molding is unloaded together with the shelf device 103 for unloading panel.

In the above embodiment, the case where the panel is the window glass for the vehicle and the frame is the molding is illustrated, but the scope of application of the present invention is not limited to this. For example, the panel is made of resin. Alternatively, it may be a metal panel.

[0046]

As described above, according to the present invention, the movable die provided in the die device is moved to a portion corresponding to a corner, and extrusion molding is performed while enlarging and changing the outer shape of the extrusion molding port at the corner portion. Since the frame is extruded and molded at the peripheral edge of the panel, and at the same time, the frame is integrated at the peripheral edge of the panel, a frame having a uniform cross-sectional shape over the entire length can be easily and easily formed on the peripheral edge of the panel. It can be fitted accurately and the appearance and design of the frame can be improved.
