[0002]

2. Description of the Related Art Conventionally, various proposals have been made as a method of mounting a frame body on the peripheral portion of a plate-like body 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 and the like on a glass plate. A thermoplastic resin is linearly formed from an extruder as a molding or a gasket having a predetermined shape. It is disclosed that, while being extrusion-molded, the molding or gasket immediately after being molded is fitted onto the peripheral edge of the glass plate by moving it around the glass plate with a pressure roll or the like and pressing it while making a round.

Further, for example, Japanese Unexamined Patent Publication No. 2-106427 discloses a method for preparing a window, which is to be attached to a window opening frame by adhering a peripheral portion of the window to a fixing flange of the window opening frame. Disclosed is that a partial adhesive ribbon having a predetermined cross section is formed in the shape of an exit orifice on the coating film 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. Has been done.

Furthermore, for example, US Pat. No. 5,108,526
The publication describes an apparatus capable of extrusion molding at various flow rates for forming a synthetic resin article on the peripheral surface of an article such as a glass plate, and in particular, the portion of the die head that is directly radially outward is the outer periphery. It is disclosed that since the corner portion or the curved portion moves faster than the substantially straight portion of the edge, the flow rate of the outer orifice is increased for the corner portion or the curved portion.

Further, for example, Japanese Patent Application Laid-Open No. 63-15716 discloses a method of manufacturing a window material, in which a window material such as glass is inserted into an injection molding die and the periphery of the glass plate is preliminarily set. It is described 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. 4-151225 describes a method for molding a resin molded product in the peripheral portion of the glass. The extrusion nozzle is fixed and the glass window is rotated to rotate the outer peripheral edge of the glass window. It is disclosed that a resin molding such as a resin molding is attached.

Further, for example, Japanese Unexamined Patent Publication No. 4-226321 describes a method for manufacturing a window glass with a gasket, in which the plastigel is directly discharged to an edge of the glass while being attached in an arbitrary shape and then melted by heating. It is disclosed that the plastigel comprises a vinyl chloride resin and a plasticizer, and has a viscosity at room temperature of 50 at a shear rate of 1 sec ^-1 .
It is described that it has a viscosity of 10,000 cps or more and 5 million cps or less, and a viscosity of 500,000 cps or less at a shear rate of 100 sec ^-1 .

Furthermore, for example, the applicant of the present invention has proposed a panel with a frame, a manufacturing method and a manufacturing apparatus thereof in Japanese Patent Application Laid-Open No. 4-261822.

[0010]

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention As described above, for example, in the method of mounting a molding, a gasket or the like on a glass plate described in JP-A-57-158479, molding of the molding or the gasket by an extrusion molding machine is performed. It is necessary to arrange the molding or the gasket fitting with the pressure bonding roll so as to be interlocked with a separately provided device so as to orbit the peripheral edge of the glass plate, and two facilities are required at the same time. It is large in size and complicated, and it is inferior to simultaneous integral molding in spite of strong mounting, and moreover, the corner portion is deformed more easily than the straight portion, and wrinkles or irregular shapes are likely to occur.

Further, for example, in the method of preparing a window described in Japanese Patent Laid-Open No. 2-106427, an extrusion head is used to simultaneously form a forming ribbon and an adhesive ribbon on a coating film applied around the rear surface of an automobile window. That is, it can be done in a one-dimensional manner. For example, a three- to four-dimensional correspondence such as mounting a frame body of a desired shape on the peripheral portion including the front and back peripheral surfaces and end faces of a glass panel or the like. It is far below. Especially since there is a frame surface on the table and it is visible, there are no measures and it is difficult to deal with it.

Still further, for example, in an apparatus capable of extrusion molding at various flow rates for forming a synthetic resin article on the peripheral surface of an article such as a glass plate described in US Pat. No. 5,108,526, only one of the articles such as a glass plate is used. Even if it can be said that it is a good method to form a synthetic resin article on the coating film surface of the peripheral edge on the back surface, for example, a frame body of the desired shape is attached to the peripheral edge portion including the front and back peripheral edge surfaces and end faces of a glass panel, etc. As described above, the shape is complicated, and it is not easy to reach the quality of the frame body when it is used as a panel with a frame.

Furthermore, for example, in the case of injection molding in the method of manufacturing a window material described in Japanese Patent Laid-Open No. 63-15716, the cost of manufacturing the die becomes large, especially when the panel becomes large. The cost is high, and when the panels are set in a pair of molds and the molds are clamped, the pressure due to the mold clamping of both molds may act on the panels, and the panels may be damaged or further damaged. There is a problem in that the formed panel appears as a scratch on the mold surface of the mold and becomes a defective product.

Further, for example, in the method of molding a resin molded article in the peripheral portion of glass described in Japanese Patent Laid-Open No. 4-151225,
Simply fix the extrusion nozzle, rotate the glass window,
Even if the resin molded product is attached to the outer peripheral edge of the glass window, the glass window is fixed, and the extruding nozzle is circulated along the peripheral edge so that the resin molded product is attached to the glass window. However, it is not always possible to prevent the appearance of wrinkles and rises of the frame body at the corner curved portion of the panel and its vicinity from being impaired, and it is easy to adopt. It is hard to say that you can do it.

Further, for example, in the method for manufacturing a window glass with a gasket described in Japanese Patent Application Laid-Open No. 4-226321, it is possible to perform the heating under normal pressure without using a mold and a high-pressure injection device, but a heat melting treatment is required. Yes, especially the discharge start part and the discharge end part are discontinuous, it is necessary to correct the plastigel to a continuous shape with a spatula, etc., which is always labor-saving and can be automated, and it is almost the same shape and surface property. It is not an exaggeration to say that it is difficult to do.

Still further, for example, in the panel with a frame body and the manufacturing method and the manufacturing apparatus thereof disclosed in Japanese Patent Application Laid-Open No. 4-261822 proposed by the present applicant, the frame bodies at the peripheral edge of the plate-shaped body are simultaneously and integrally extruded. Although molding can be performed reliably and efficiently, in order to exert more adhesive strength, a separate pretreatment such as primer coating is required in some cases, and one step is extra.

Here, as described above, when forming the frame body, or at least before, the adhesive layer molding portion for forming the adhesive layer on the peripheral portion, and the frame forming the frame body for covering at least the surface of the adhesive layer. The extruding nozzle provided with the body forming section is generally used in comparison with the conventional case in which the frame body is extruded at the treated portion using the window glass pretreated with the adhesive on the peripheral portion. Instead of using the adhesive layer forming nozzle and the frame body forming nozzle separately, the adhesive layer and the frame body are formed on the peripheral portion of the plate-like body such as wind glass only by one extrusion forming nozzle and in one step. This is because it can be formed at the same time or nearly at the same time, and the adhesive force is sufficiently strong while controlling the adhesive force freely. Profitable table Dimensional accuracy form a good thing high quality in sex, because the ones as possible the function of the frame Te sufficiently exhibited.

Further, not only the so-called base layer is surely provided, but the adhesive layer molding portion is provided in the region of the frame molding portion or immediately before or in the range which can be arranged at the rear portion of the extrusion molding nozzle. This is because the controllability of the adhesive strength can be further enhanced, and since one extrusion molding nozzle is equipped with it, it is possible to use various adhesives or to exhibit their functionality that cannot be obtained by the conventional primer-like treatment.

Further, at least one of the die body and the die is provided with a frame material supply space, and a die body is provided with an adhesive layer molding portion in which at least a frame material and / or an adhesive feeding path and an adhesive layer molding space are arranged. And a die having a frame body forming portion having at least a frame body forming space having a side opening portion and a frame body extrusion port, and detachable so that the die body and the side opening portion arranged on the die body are at least connected to each other. The extruding nozzle that is engaged with is designed to make it easier to change the cleaning etc. when using various adhesives and frame materials, and replace the mouthpiece to support various frame bodies as needed. This is to get it.

Furthermore, when forming the frame, or at least before, forming the frame by forming an adhesive layer forming portion for forming an adhesive layer on the peripheral portion and a frame for covering at least the surface of the adhesive layer. A portion of the peripheral edge of the plate-shaped body is inserted from the side opening of the extrusion-molded nozzle so as to surround the plate-shaped body, Forming a molding space and a cavity space for the cross-sectional shape of the frame and / or the adhesive layer, and then passing through the adhesive feeding path and the frame material feeding path inside and outside the die body to bond from the cavity space. The agent and the frame material are fed, firstly the adhesive layer is formed on the surface of the adhesive layer and then the frame layer is formed on the surface of the adhesive layer at the same time, and the adhesive layer is extruded from the extrusion port through the molding space. Board While moving the body and the extrusion molding nozzle relative to each other along the peripheral portion of the plate-shaped body, the adhesive layer that is connected to the peripheral portion of the plate-shaped body with the entire circumference or a part thereof left The method of manufacturing a plate-like body with a frame body that forms a frame body of a predetermined substantially uniform cross-sectional shape as a stratum and fixes and integrates at the same time is that the window glass itself which is a plate body has a complicated curved surface, The rim of the window glass is held substantially horizontally by the die of the extrusion molding nozzle and the die main body to absorb the dimension, and the state in the molding space of the die from the cavity space, the linear portion of the rim of the window glass, and the like. Extrusion pressure of the frame material to be fed changes as a result of the molding space and the cavity space, which reach the extruding cross-sectional shape formed by the peripheral portion of the corner portion and the extruding port formed in the die in advance, differ in volume. Strange However, the extrusion molding frame cannot maintain a uniform cross-sectional shape, the factors that determine the cavity space internal pressure, the molding conditions so as to offset the extrusion pressure change of the frame material caused by the volume change of the cavity space. For example, the extrusion amount and the take-up speed are controlled, and more specifically, for example, in the cavity pressure control by increasing or decreasing the screw rotation of the extruder or by increasing or decreasing the take-up speed (the relative moving speed of the window glass and the extrusion port), From the quick response to the change immediately below the outlet, it was solved by controlling the relative moving speed and the like or a combination thereof according to the change of the cavity volume, and the frame itself which is the frame itself also It has a three-dimensionally complicated shape that is surrounded by the peripheral portions of both the front and back surfaces and the end surface, and the outer surface of the frame is also visible. However, it is possible to absorb it by controlling the supply amount of the frame material and / or the moving speed in response to a great variety of factors such as a demand for excellent surface properties, and the peripheral edge of the panel. A frame body having a predetermined uniform cross-sectional shape, which is continuously provided along the portion or is partially omitted, can be fixed and integrated.

The frame body having a predetermined uniform cross-sectional shape is
Of course, it goes without saying that frame bodies of various shapes such as a frame body whose shape can be varied at a certain place are also within the scope of the present invention. In addition, as the frame material, especially a thermoplastic resin,
In particular, it is a vinyl chloride resin, and is also a thermosetting resin such as a urethane resin, and a synthetic resin or rubber resin such as a thermoplastic elastomer such as an olefin resin or a styrene resin.

As the adhesive, for example, one containing α-cyanoacrylate as a main component [Product name Aron Alpha (Toa Gosei Chemical Industry Co., Ltd.)] and one containing modified nylon [Product name Aron] Mighty FS (Toagosei Kagaku Kogyo Co., Ltd.) or other thermosetting adhesives or those containing copolyester as a main component [Alomelt FES series (Toagosei Kagaku Kogyo Co., Ltd.)], mainly butyl The components include [Meltron HB (trade name) manufactured by Diabond Industry Co., Ltd.] and thermoplastic adhesives such as a mixture of two or more kinds of the same type, and a mixture of these with a vinyl chloride type.

Furthermore, the relative movement is the movement due to the rotation of the plate-like body, because the rotation can be easily controlled. The extrusion molding nozzle of the present invention can be downsized and made flexible, and in some cases, the extrusion molding nozzle can be sufficiently rotated to follow the peripheral edge of the plate-shaped body.

[0036]

As described above, according to the method of manufacturing the extrusion molding nozzle and the plate-shaped body with the frame of the present invention, the adhesive layer is formed on the peripheral edge of the plate-shaped body at or before the frame is formed. An extrusion molding nozzle comprising an adhesive layer molding portion and a frame molding portion forming a frame body that covers at least the surface of the adhesive layer, and the peripheral edge portion of the plate-like body is relatively moved by using the extrusion molding nozzle. By controlling the movement of the adhesive layer, which is a so-called underlayer on the periphery of which is controlled so as to move at the same time, and the frame body at the same time or almost at the same time, and extruding and integrating them, it is possible to achieve an extremely high degree compared with the frame material. The low viscosity thermosetting adhesive also overcomes the need for the application point to be very close to the plate-shaped control point for the nozzle, and the adhesive does not stick out of the frame or slip the frame material. Can be extruded without losing moldability Thing becomes, and obtained a can also be used a so-called two-color molding manner with thermoplastic adhesive is a hot melt, of course no strength, for example, peel strength is sufficiently ensured or what times 1Kg / cm ² in the conventional extrusion molding It is possible to form the frame body around the periphery of the plate body with the adhesive force being sufficiently controlled, and the sticking and integration can be easily performed by extrusion molding, and the plate body is not damaged or scratched, and the frame body is not wrinkled or raised. A framed plate-like body that does not occur, has a good surface appearance, is uniform in cross-section, has an accurate overall size, can be automated and labor-saving, and has high efficiency, and can fully demonstrate its function as a frame. It can be manufactured.
