DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to panels, in particular inorganic and organic glass plates, for example panels of flat or bent plate, such as raw or reinforced single plate, laminated or double glazed glass. The present invention provides a manufacturing method for forming a frame by extrusion molding, and a method for manufacturing a panel with a useful frame which can be adopted for various window members or door members for construction and vehicles. It is.

[0002]

2. Description of the Related Art Conventionally, various proposals have been made for a method of mounting a frame on a peripheral portion of a panel such as a window glass for a vehicle.

For example, Japanese Patent Application Laid-Open No. 57-158479 describes a method of mounting a molding, a gasket or the like on a glass plate. A thermoplastic resin is formed in a straight line as a molding or gasket of a predetermined shape from an extruder. It is disclosed that, during extrusion molding, the molding or gasket immediately after the molding is moved around the glass plate by a pressure roll or the like by a pressing roll or the like, and pressed and fitted while making a circuit.

Further, for example, Japanese Patent Application Laid-Open No. 2-106427 discloses a method for preparing a window. The method includes assembling a window edge frame by bonding a peripheral portion of the window to a fixing flange of the window frame. Disclosed is that a partial adhesive ribbon having a predetermined cross section is formed and arranged in the shape of an outlet orifice on the coating surface of the peripheral portion of the window by the same extrusion of different adhesive materials from a head which is a predetermined extrusion nozzle. Have been.

[0005] Still further, see, for example, US Patent No. 5,108,526.
Describes a device that can be extruded at various flow rates to form a synthetic resin article on the peripheral surface of an article such as a glass plate. It is disclosed that the corner or the curved portion moves faster than the substantially straight portion of the edge, so that the flow rate of the outer orifice on the corner or the curved portion is increased.

Further, for example, Japanese Patent Application Laid-Open No. 63-15716 discloses a method for manufacturing a window material. A window material such as glass is inserted into an injection molding die, and the window material is previously formed on the periphery of the glass plate. It describes that an adhesive layer is applied, the inside of the adhesive layer is sandwiched by a mold, and a frame is injection-molded on the adhesive layer outside the sandwiching portion.

Further, for example, Japanese Patent Application Laid-Open No. Hei 4-151225 discloses a method of molding a resin molded product at a peripheral portion of a glass. The extrusion nozzle is fixed, and the outer periphery of the glass window is rotated by rotating the glass window. Discloses mounting a resin molded product such as a resin molding.

[0008]

As described above, for example, in the method of mounting a molding or a gasket on a glass plate described in Japanese Patent Application Laid-Open No. 57-158479, molding of a molding or a gasket by an extruder is required. It is necessary to arrange the fitting of the molding or the gasket by the press roll so as to be linked with a separately provided device so as to move around the periphery of the glass plate, and two facilities are required at the same time. It is easy to become complicated due to the increase in size, and it is inferior to simultaneous mounting, although it is said that it is firmly mounted. In addition, it is more likely to have a deformed shape at the corner portion than to a straight portion, and to be wrinkled or irregular.

[0009] For example, in the method of preparing a window described in Japanese Patent Application Laid-Open No. 2-106427, a molding ribbon and an adhesive ribbon are simultaneously molded by an extrusion head onto a coating film applied around the back surface of an automobile window. It can be performed in a one-dimensional correspondence, for example, a three- to four-dimensional correspondence such as mounting a frame of an intended shape on a peripheral portion including front and back peripheral surfaces and end surfaces of a glass panel or the like. It is far from possible. In particular, there is no measure because the surface of the frame is visible in the table and it is difficult to respond.

[0010] Further, in an apparatus which can be extruded at various flow rates to form a synthetic resin article on the peripheral surface of an article such as a glass plate described in US Pat. Even if it can be said that it is a good method to form a synthetic resin article on the peripheral coating film surface on the back surface, for example, attach the frame of the desired shape to the peripheral portion including the front and back peripheral surfaces and the end surface of the glass panel etc. As described above, the shape of the frame is complicated, and when the panel is used as a framed panel, it is not easy to reach the quality required for the frame to be viewed externally.

In addition, for example, in the case of the injection molding by the method of manufacturing a window material described in Japanese Patent Application Laid-Open No. 63-15716, especially when a panel is enlarged, the cost of manufacturing the mold becomes large. When the panel is set in a pair of molds and the mold is clamped, the pressure due to the mold clamping of the two molds acts on the panel, and the panel may be damaged or further damaged. The resulting panel has problems such as irregularities appearing on the mold surface of the mold as well as defective products.

[0012] For example, in the method of molding a resin molded product at the periphery of a glass described in JP-A-4-151225,
Simply fix the extrusion nozzle, rotate the glass window,
Even if the resin molded product was attached to the outer periphery of the glass window, the glass window was fixed, and simply transferred to a means in which the extrusion nozzle was rotated along the periphery to attach the resin molded product. It is not always possible to prevent the appearance such as surface wrinkles or floating of the frame in the corner curved portion of the panel or in the vicinity thereof, and it is not always easy to adopt. It is hard to say that you can.

[0013]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems. For example, even if the shape of a window glass is changed to a flat plate shape, for example, both sides of the periphery of the window glass may be used. And molding of synthetic resin can be simultaneously extruded integrally around the end face.
Particularly, even in the corner curved portion of the window glass, high-quality extrusion molding can be performed with a uniform cross section similar to the linear portion, and a complicated two to four dimensional,
In particular, the intended purpose can be achieved by enabling three- or four-dimensional correspondence, and there is no trouble in operation, high quality and good dimensional accuracy, and windows for construction Another object of the present invention is to provide a method for manufacturing a panel with a frame which is useful not only for doors but also for automobile windows.

That is, the present invention provides a method for manufacturing a panel with a frame by extruding a frame having an intended frame mounted on a peripheral portion of the panel having a linear portion and a curved corner portion. At the periphery of the panel
And a molding space for the cross-sectional shape of the frame and a cavity space for the die body between the extrusion port formed in the die of the extrusion molding die apparatus , and then a material in the die body of the die apparatus. A frame material fed from a cavity space which is also a material feeding path by flowing through the feeding path,
While extruding from the extrusion port through the molding space, the panel and the die device are relatively moved along the panel peripheral portion, and the moving speed is lower than the speed in the straight portion at the corner curved portion. Forming a frame having an intended uniform cross-sectional shape connected continuously along the peripheral edge of the panel by simultaneously moving the frame while controlling the frame to be integrated with the peripheral edge of the panel. A method for manufacturing a panel with a frame, characterized by comprising:

The method for manufacturing a panel with a frame as described above, wherein the control for delaying the moving speed in the corner curved portion is a control for changing the moving speed in accordance with the radius of the corner curved portion. . The moving speed is controlled in accordance with a volume change and / or an internal pressure change in a cavity space and / or a molding space of a die in the die body. Panel manufacturing method. Still further, the present invention provides the above-described method for manufacturing a panel with a frame, wherein the relative movement is movement by rotation of the panel.

Here, the reason why the moving speed is controlled in the corner curved portion so as to be lower than the speed in the linear portion is that the window glass has a complicated curved surface and the window glass itself has a complicated curved surface. The dimensional absorption is performed while the peripheral portion of the die is held substantially horizontally by the die of the die device and the die body, and as shown in FIGS. 9 and 10,
In the straight portion and the corner curved portion of the window glass periphery, the molding space and the cavity space up to the extrusion cross-sectional shape formed by a part of the window glass periphery and the extrusion port formed in advance in the die are shown in FIG. As shown in FIG. 9 and FIG. 10, which are cross-sectional views taken along the line III-III, the volume changes differently, and as a result, the extrusion pressure of the fed frame material changes, and the extruded frame becomes uniform. A factor that determines the internal pressure of the cavity space, as a molding condition, controls the extrusion amount and the take-up speed so that the cross-sectional shape cannot be maintained, so as to offset the change in the extrusion pressure of the frame material caused by the change in the volume of the cavity space. More specifically, by increasing or decreasing the screw rotation of the extrusion device, or by increasing the take-up speed (the relative movement speed between the window glass and the extrusion port). Of the cavity internal pressure control, by responding to the change immediately below the extrusion port, it was solved by controlling the relative movement speed according to the change in the cavity volume, and the molding itself was also on the front and back sides of the window glass periphery It has a complicated variety of two- and four-dimensional shapes that are surrounded by the peripheral edge with the end face, and furthermore, the outer surface of the molding is externally visible. At least the moving speed at the corner curved portion is made slower than the moving speed at the linear portion, thereby being able to be absorbed.

[0017]

As described above, according to the method of manufacturing a panel with a frame of the present invention, the frame material fed from the material feeding path of the die device is extruded from the extrusion port through the cavity space and the molding space. Overcoming the two- and four-dimensional factors by controlling the relative movement speed of the panel and the die device along the peripheral edge of the panel, especially at the corner curved part, so as to be slower than the linear part. By doing so, the frame body can be simultaneously molded and fixed to the peripheral edge of the panel, and it can be easily and efficiently extruded, and the breakage and scratches of the panel as well as the occurrence of wrinkles and floating of the frame body can be eliminated and uniform quality can be achieved. The appearance can be improved, and the uniform dimensions can be manufactured with a uniform cross-section, and the desired panel with a frame can be obtained.
