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 great deal of labor is required for the work of fitting the frame body to the peripheral portion of the panel and adhering it, but also There is a problem in that "wrinkles" and "lifting" occur in the frame at the corners of the panel and in the vicinity thereof, and the appearance and design are impaired.

Further, JP-A-62-280019, JP-A-61-230930 or JP-A-3-19.
When the cross-sectional shape of the frame body is changed along the longitudinal direction as proposed in Japanese Laid-Open Patent Publication No. 22 and the like,
Even if the cross-sectional shape of the frame itself is formed with high accuracy, it may not be possible to dispose the predetermined cross-sectional shape at a predetermined position because of a positional deviation when it is mounted on the panel.

In order to solve the trouble of mounting the frame on the peripheral portion of the panel and the problem of the appearance and design, and to eliminate the positional displacement of the frame, it is disclosed, for example, in Japanese Patent Laid-Open No. 63-15716. Things are 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.

[0005]

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 JP-A-4-151225, in order to improve the mountability of the frame body, extrusion molding is carried out 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, this proposed method merely extrudes a frame body having a constant cross-sectional shape into a panel, and therefore, when the cross-sectional shape of the frame body is changed along the longitudinal direction as described above, Is not applicable.

In view of the above-mentioned conventional problems, the present invention fits the frame body in the peripheral portion of the panel even when mounting the frame body having a changed cross-sectional shape along the longitudinal direction. A method of manufacturing a panel with a frame body, which enables easy and accurate work, and can prevent "wrinkles" or "lifting" of the frame body at the corners of the panel or in the vicinity thereof. The purpose is to provide.

[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. By relatively moving the die device along the peripheral edge of the panel, the frame body connected to the peripheral edge of the panel is extruded, and the frame body is joined and integrated with the peripheral edge of the panel, Provided in the die machine Was by the movable die is moved relative to the fixed die has a configuration said to perform extrusion while the opening shape is changed in the extrusion port.

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 such means, while the frame material fed from the material feeding path of the die device is extruded 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 edge of the panel is easily and accurately manufactured. At this time, by appropriately moving the movable die provided in the die device,
Since the extrusion molding is performed while changing the outer shape of the extrusion molding port, the extrusion molding is performed so that the cross-sectional shape of the frame body integrally joined to the peripheral portion of the panel is changed along the longitudinal direction. Then, a predetermined cross-sectional shape is arranged at a predetermined position.

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 has a predetermined orientation with respect to the holding arm 62 of the panel holding device 60, and in this embodiment, the lower edge of the peripheral edge of the window glass 3 faces the die device 11. Is set to. Then, the window glass 3 is placed on the suction cup 63 arranged on the holding arm 62 of the panel holding device 60.

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 of the panel supply receiving shelf 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 FIG. 7, and the extrusion molding port is enlarged to the maximum opening area. And as mentioned above, wind glass 3
Is inserted into the extrusion molding port, 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. When this molding space is formed, the molding material P is supplied to the material feeding path of the die device 11, 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 speed. As a result, as shown in FIGS. 8 and 9, 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. 9, when the first corner portion of the peripheral edge of the window glass 3 reaches the position of the extrusion port of the die device 11, the first and second swivel arms 3 are provided.
Simultaneously with the turning of 6, 41, the turntable 48 is turned, 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.

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 tilting table 57 is tilted in accordance with 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 the first and second Both swivel arms 36, 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 second die 132 of the die device 11 moves from the position shown in FIG. 7 to the position shown in FIG. 6 at the side portion from the upper end of the right edge of the peripheral edge of the window glass 3 to the second corner portion. While being extruded, the corner molding 4B is extruded while the bulging thickness of the molding 4 is reduced. In this case, 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 as described above. Therefore, the molding having a predetermined cross-sectional shape corresponding to each part of the windshield 3 is accurately formed without causing a positional deviation, and particularly, in the corner portion and the vicinity thereof, the bulging portion of the corner molding 4B is located. It is designed to be molded with high precision.

After the extrusion molding of the corner molding 4B is completed, the upper edge of the peripheral edge of the window glass 3 is located at the die unit 1.
The extrusion molding of the upper molding 4A is performed from the time when the extrusion molding opening 1 is reached. In this case, die device 11
The second die 132 is set to the position shown in FIG. 6, and the extrusion port is reduced to the minimum opening area.

The peripheral portion of the window glass 3 held by the panel holding device 60 in this manner is moved by the moving device 2.
While being kept in a horizontal state by means of 4, it is always inserted and moved into the extrusion molding port of the die device 11 with a constant insertion depth. At this time, since the second die 132 provided in the die device 11 is controlled so as to be synchronized with the relative movement between the window glass 3 and the die device, the outer shape of the extrusion molding port is made to correspond to the glass position. Extrusion molding is performed while changing. As a result, a molding 4 having a different cross-sectional shape depending on each part is extruded and formed on the peripheral edge of the window glass 3 with high accuracy and at the same time. The molding 4 is integrally bonded to the peripheral edge of the. 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.
After that, the window glass 2 with molding is mounted on the pair of panel receiving arms 101 of the panel unloading shelf device 103 by the panel take-out device 95.

It is connected to the device. The molding 14 is provided at the left edge of the second die 152 in the drawing, that is, the edge portion of the first die 151 that shields the extrusion port.
An extruded piece 155 corresponding to a part of the decorative portion 142 and the leg portion 141 of 0 is formed.

On the side surface of the extrusion molding port provided in the first die 151, the extrusion molding port is opened laterally so that a part of the peripheral edge of the window glass 300 can be inserted into the extrusion molding port. A side opening is formed. Then, by the peripheral edge portion of the window glass 300 inserted into the extrusion molding opening from this side opening, the extrusion segment 155 of the second die 152, and the peripheral wall surface of the extrusion molding opening of the first die 151, A molding space corresponding to the cross-sectional shape of the molding 150 is configured. The shape of the outer opening of the molding space is changed by horizontally moving the second die 152.

Also in this case, the movement of the second die 132 is controlled so as to be synchronized with the relative movement of the window glass 3 and the die device, and the predetermined crossing corresponding to each part of the window glass 3 is performed. The molding having a surface shape is configured to be accurately molded without displacement. Particularly for the corner portion, the corner molding 4B is accurately formed.

That is, the wind molding 140
