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 the frame body, but also to the corner of the panel. 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 body 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.

Further, in JP-A-58-113480 and JP-A-58-113482, in order to reduce the number of mounting steps, an injection molding die is used and the peripheral portion of a window plate as a panel is used. It is disclosed that a frame is integrally molded and a retainer as a mounting member is embedded in the frame.

[0005]

However, in the case of performing the injection molding as described above, especially when the panel becomes large, the cost for 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 molding method is merely a method of integrally molding the frame body on the peripheral portion of the panel, and there is no disclosure of means for efficiently mounting the integrally molded body and the manufacturing method thereof.

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 body, which can prevent the occurrence of the above-mentioned problem and can perform efficient attachment.

[0008]

In order to solve the above-mentioned conventional problems, in the means according to the present invention, a frame is mounted on the peripheral portion of the panel and a predetermined mounting member is attached to the frame. In the method of manufacturing a panel with a frame body for manufacturing a panel with a frame body, in the extrusion molding port provided in the die device for extrusion molding, a part of the peripheral portion of the panel from the side opening portion A molding space corresponding to the cross-sectional shape of the frame body is formed between the peripheral portion of the panel and the extrusion molding port, and the frame material fed from the die device is then formed in the molding space. Then, while extruding from the extrusion molding port, the panel and the die device are relatively moved along the peripheral edge of the panel, and a frame body connected to the peripheral edge of the panel is extruded and joined to the peripheral edge of the panel. Then integrated and then on When the frame is in a softened state, it has a configuration in which a part of the mounting member so as to embed the frame body.

[0009]

According to such means, while the frame material fed from the material feeding passage of the die device is pushed out from the extrusion molding port through the molding space, the panel and the die device are brought to the peripheral portion of the panel. By being relatively moved along the frame, a panel with a frame in which the frame is integrally joined to the peripheral edge of the panel is easily manufactured, and the panel with the frame is embedded in the frame. It can be efficiently mounted by the mounting member.

Will be returned. Then, the window glass 1 is adsorbed to each suction cup 63 of the panel holding device 60, and the loading of the window glass 1 to 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 1 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 1 on the side facing the side opening of the die device 11 is in a horizontal state. The holding arm 62 of 60 and the window glass 1 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 1 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 of the window glass 1 held by the panel holding device 60 is inserted into the extrusion molding opening from the side opening of the die device 11 by a certain amount. Then, as described above, by inserting the window glass 1 into the extrusion molding port, a molding space corresponding to the cross-sectional shape of the molding 2 is formed between the peripheral edge portion of the window glass 1 and the inner peripheral wall of the extrusion molding port 13a. To be done. 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.

When the molding material P is extruded from the extrusion molding port 13a, the first and the second rotating arms 3 are
6 and 41 are respectively swung in a predetermined direction, and the peripheral edge of the window glass 1 is moved at a controlled predetermined speed. Then, when the corner portion of the peripheral edge of the window glass 1 reaches the position of the extrusion molding port 13a of the die device 11,
Simultaneously with the turning of the first and second turning arms 36, 41, the turntable 48 is turned, and the die device 11 is relatively moved along the rounded surface of the first corner of the window glass 1. Further, since the tilting table 57 is tilted in accordance with the curvature of the glass surface at the first corner portion, the die device 11
The first corner portion of the window glass 1 is maintained in a horizontal state with respect to the extrusion molding port.

The peripheral portion of the window glass 1 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 into the extrusion molding port of the die device 11 at a constant insertion depth and moved at a controlled predetermined speed. As a result, the molding 2 having a uniform cross-sectional shape over the entire length is extruded on the peripheral edge of the window glass 1 and at the same time,
The molding 2 is integrally bonded to the peripheral edge of the window glass 1 by the adhesive applied to the peripheral edge of the window glass 1. When the entire length of the molding 2 is extruded along the peripheral edge of the window glass 1, the supply of the molding material P to the material supply path of the die device 11 is temporarily cut off.

Next, while the molding 2 is in the softened state, the mounting member mounting device 110 is started to operate, and the mounting member 6 gripped by the hand 114 of the mounting member mounting device 110 is shown by a chain line in FIG. As shown in FIG. That is, the plate portion 6a of the mounting member 6 is embedded in the molding 2.

(Preliminary Step) When the supply of the molding material is cut off and the mounting member 6 is installed,
The slide table 26 is retracted to the original position. Then, the window glass with molding is removed from the side opening of the extrusion port. Thereafter, the window glass with molding is placed on the pair of panel receiving arms 101 of the panel unloading receiving shelf device 103 by the panel unloading device 95.

The window glass with molding placed on the panel unloading and receiving rack device 103 is a cooling device 1.
It is cooled by the cold air 122 from the blowout nozzles 121 of 20. As a result, the molding 2 of the window glass with molding is solidified and the mounting member 6 is fixed.

As described above, in the pretreatment step, the window glass 1 is 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 panel is the window glass for the vehicle and the frame is the molding, but the scope of the present invention is not limited to this. For example, the panel is made of resin. Alternatively, it may be a metal panel.
