Detailed Description

Hereinafter, an embodiment of a manufacturing apparatus for a plate-like body with a resin frame according to the present invention will be described with reference to the drawings.

Fig. 1 is an enlarged cross-sectional view of a peripheral edge portion of a resin frame-equipped plate-like body (hereinafter referred to as "resin frame-equipped window glass") 10 manufactured by a resin frame-equipped plate-like body manufacturing apparatus 30 (see fig. 4 and 5) according to an embodiment. As shown in fig. 1, a window glass 10 with a resin frame includes a window glass 12, a resin frame 14, and a decorative lace 16. The window glass 12 is an example of a plate-like body.

The window glass 12 may be inorganic glass or organic glass. As the inorganic glass, for example, soda lime glass, aluminosilicate glass, borosilicate glass, alkali-free glass, quartz glass, and the like can be used without particular limitation. The window glass 12 is preferably inorganic glass from the viewpoint of scratch resistance, and the window glass 12 is preferably soda lime glass from the viewpoint of formability. When the window glass 12 is soda lime glass, transparent glass, green glass containing a predetermined amount of iron or more, and UV cut green glass can be preferably used. As the window glass 12, privacy glass (also referred to as dark gray glass) having a visible light transmittance of 70% or less may be used. Specifically, in the window glass 12, the Fe is converted by the adjustment₂O₃The total iron content of (2) may be such that the visible light transmittance of the window glass 12 is 70% or less.

As an example of the composition of the privacy glass, the privacy glass contains, as a main glass composition, expressed in mass% based on oxides: SiO 2₂:66～75％、Na₂O:10～20％、CaO:5～15％、MgO:0～6％、Al₂O₃:0～5％、K₂0 to 5% of O, 0.13 to 0.9% of FeO, and Fe₂O₃0.8% or more and less than 2.4% of total iron, and TiO₂More than 1% and not more than 5%, and containing 100 to 500 mass ppm of CoO, 0 to 70 mass ppm of Se, and 0 to 800 mass ppm of Cr, based on the total amount of the main components of the glass₂O₃And CoO, Se and Cr₂O₃The total amount of (B) is less than 0.1 mass%.

Further, as for the privacy glass, it is described in detail in, for example, international publication No. 2015/088026, the contents of which are incorporated in this specification by reference.

The inorganic glass may be any of non-strengthened glass and strengthened glass. The unreinforced glass is formed by forming molten glass into a plate shape and annealing the formed glass. The tempered glass is one in which a compressive stress layer is formed on the surface of an unreinforced glass.

The tempered glass may be any of physically tempered glass such as air-cooled tempered glass and chemically tempered glass. In the case of physically strengthened glass, the glass surface can be strengthened by an operation other than annealing, for example, by rapidly cooling a uniformly heated glass sheet from a temperature near the softening point in the bending process, thereby generating a compressive stress layer on the glass surface by utilizing the temperature difference between the glass surface and the inside of the glass.

In the case of chemically strengthened glass, the glass surface can be strengthened by, for example, applying a compressive stress to the glass surface by an ion exchange method or the like after bending. Further, glass absorbing ultraviolet or infrared rays may be used, and transparent glass is more preferable, but a glass plate colored to such an extent that transparency is not impaired may also be used.

On the other hand, as a material of the organic glass, polycarbonate, for example, acrylic resin such as polymethyl methacrylate, and transparent resin such as polyvinyl chloride and polystyrene may be mentioned.

In order to prevent the glass pieces from scattering when the window glass 12 is broken, a scattering prevention film may be attached to the surface of the window glass 12.

The shape of the window glass 12 is not particularly limited, and various shapes and shapes processed to have a curvature are possible. As the bending of the window glass 12, gravity forming, press forming, roll forming, or the like can be used. The method of forming the window glass 12 is not particularly limited, but in the case of inorganic glass, for example, a glass plate formed by a float method or the like is preferable. When the window glass 12 is an inorganic glass having a curved shape, the window glass 12 may be curved after being formed by the float process. The bending is performed by heating and softening the glass. The heating temperature of the glass in bending is about 500 to 700 ℃.

When the window glass 12 is curved, it may be a single curved shape that is curved in only one direction, or may be a multi-curved shape that is curved in two or more directions. When the window glass 12 is curved, it is preferably curved so as to be convex toward the vehicle outside. When the window glass 12 is curved, the radius of curvature of the window glass 12 is preferably 1000mm or more and 100000mm or less.

The thickness of the window glass 12 is preferably 0.3mm to 5.0mm, more preferably 0.5mm to 3.0mm, and still more preferably 0.7mm to 1.9 mm.

The window glass 12 may be provided with a dark opaque shielding layer (dark ceramic layer) such as black formed in a band shape along the peripheral edge portion. The shielding layer has a function of concealing the adhesive applied between the glass plate 12 and the resin frame 14 when the window glass 12 is mounted on the body of an automobile. The shielding layer is formed by applying a ceramic paste on the surface of the window glass 12 and then firing the paste. The thickness of the shielding layer is preferably 3 μm or more and 15 μm or less. The width of the shielding layer 30 is not particularly limited, but is preferably 20mm to 300 mm.

When the window glass 12 is mounted on an automobile, the outer glass sheet positioned on the outside of the automobile and the inner glass sheet positioned on the inside of the automobile may be laminated glass bonded to each other with an interlayer interposed therebetween. As the interlayer film, in addition to an interlayer film formed of polyvinyl butyral (PVB), particularly when water resistance is required, an ethylene vinyl acetate copolymer (EVA) can be preferably used, and an acrylic photopolymerizable prepolymer, an acrylic catalytic polymerizable prepolymer, an acrylate/vinyl acetate photopolymerizable prepolymer, polyvinyl chloride, or the like can be used. The vehicle exterior glass panel and the vehicle interior glass panel may have the same composition, shape, thickness, or may be different.

As the resin constituting the resin frame 14, a thermoplastic resin can be exemplified. Examples of the thermoplastic resin include polyvinyl chloride resins and general thermoplastic resins such as polyolefin-based, polyester-based, polystyrene-based, polyamide-based, and polyurethane-based elastomers.

Fig. 2 is an enlarged cross-sectional view of the lace 16. As shown in fig. 1, the decorative lace 16 is provided on a surface 14A of the resin frame 14, and the resin frame 14 is integrally formed with a peripheral edge portion 12A of the window glass 12. Here, the surface 14A of the resin frame 14 is a surface facing the vehicle exterior side when the window glass 10 with the resin frame is fixed to a vehicle body window opening (not shown).

Returning to fig. 2, the lace 16 includes a main body 18 having a substantially U-shaped cross section, and a film 20 provided on a surface 18A of the main body 18. Here, the surface 18A of the body portion 18 is a surface constituting a design surface of the decorative lace 16, and is a surface facing the vehicle exterior side when the window glass 10 with a resin frame body is fixed to a vehicle body window opening portion (not shown).

Fig. 3 is a plan view of the main body portion 18 of the lace 16. As shown in fig. 3, the main body 18 is formed in a substantially L-shape in plan view. According to the body portion 18 having such a shape, for example, as shown by the two-dot chain line, when the window glass 12 has a rectangular shape, it is arranged along 2 adjacent sides of the window glass 12. The above shape of the body portion 18 is an example. For example, in the case of the decorative lace 16 arranged along 1 side of the window glass 12, the shape of the body portion 18 is linear. In the case of the decorative lace 16 arranged along 4 sides of the window glass 12, the main body 18 has a frame shape. The main body 18 is a magnetic body, and is manufactured by molding a magnetic material by a manufacturing method such as press molding, extrusion molding, or drawing. Examples of the magnetic material include iron oxide, chromium oxide, cobalt, ferrite, and the like.

The film 20 shown in fig. 2 is preferably a resin film, for example. Examples of the resin include polyvinyl chloride resin, acrylic resin, polyester resin, and polyvinylidene fluoride resin. The film 20 may be formed of, for example, a colored layer and an adhesive layer, or may be formed to include these layers and a clear layer. The colored layer can set the color of the decorative lace 16 to be the same color as the color of the resin frame 14 or the vehicle body. The colored layer can be formed by mixing a coloring pigment into a resin. Further, as the above adhesive layer, an acrylic or epoxy adhesive layer can be exemplified. The thickness of the film 20 thus configured is, for example, 25 μm to 100 μm. The film 20 is not an essential component of the lace 16, and may be the lace 16 composed only of the body portion 18.

Next, an example of the apparatus 30 for manufacturing the resin frame-equipped window glass 10 according to the embodiment will be described with reference to fig. 4 and 5.

Fig. 4 is a sectional view of a main part of the first mold 32 constituting the manufacturing apparatus 30, and fig. 5 is a sectional view of a main part of the first mold 32 and the second mold 34 constituting the manufacturing apparatus 30.

As shown in fig. 4 and 5, the manufacturing apparatus 30 of the embodiment includes a die 36. The mold 36 has a cavity space 38 for forming the resin frame 14 on the window glass 12. The mold 36 includes the first mold 32 functioning as a mold for forming a pattern design surface. The first mold 32 is made of a non-magnetic material, and has a mounting surface 40 on which the decorative lace 16 is mounted.

The nonmagnetic material constituting the first mold 32 is preferably, for example, a nonmagnetic steel having a magnetic permeability of 1.02[ H/m ] or less, and examples of such a nonmagnetic steel include austenitic stainless steel, high manganese steel, high nickel alloy, and the like. Further, aluminum or copper may be used, and if the resin of the resin frame 14 is a polyvinyl chloride resin, austenite steel SUS304 having high corrosion resistance is preferable.

The attachment surface 40 is formed in a part of a concave surface 42 defining the cavity space 38, and is formed in a concave shape along a surface 18A (see fig. 2) of the body portion 18 of the lace 16. Thus, when the decorative lace 16 is mounted on the mounting surface 40, the surface 18A as the design surface is closely bonded to the mounting surface 40.

Furthermore, the die 36 has an electromagnet 44. The electromagnet 44 is disposed on the back surface 46 side opposite to the mounting surface 40 of the first mold 32, and is capable of holding the decorative lace 16 mounted on the mounting surface 40 by magnetic force. That is, the manufacturing apparatus 30 of the embodiment has the following configuration: the electromagnet 44 is not exposed to the mounting surface 40, and the electromagnet 44 is disposed with the first mold 32 as a non-magnetic body interposed therebetween. In addition, the electromagnet 44 is described later.

As shown in fig. 5, the mold 36 includes the second mold 34 that functions as a mold for molding the back surface of the product. The second mold 34 is disposed to face the first mold 32.

The first die 32 and the second die 34 are provided so as to be relatively movable forward and backward in the horizontal direction indicated by arrow a in fig. 5, and in the state of fig. 5 where they are advanced and brought into contact with each other, a cavity space 38 is defined between the first die 32 and the second die 34. At this time, the window glass 12 is disposed between the first mold 32 and the second mold 34 so that the two main surfaces 12B, 12B of the window glass 12 facing each other are positioned in a direction substantially perpendicular to the ground surface (not shown). The main surface 12B is disposed substantially in the vertical direction, which means a form in which a line segment connecting an upper end portion and a lower end portion of the window glass 12 when the window glass 12 is attached to the mold 36 is in a direction close to the vertical direction with respect to the horizontal direction. For example, the line segment is preferably within a range of ± 20 ° with respect to the vertical direction, and more preferably within a range of ± 10 °.

The first mold 32 and the second mold 34 are configured into a frame shape having a predetermined length corresponding to the shape of the peripheral edge portion 12A of the window glass 12. A plurality of electromagnets 44 shown in fig. 5 may be arranged at predetermined intervals in the longitudinal direction of the first mold 32.

As an example, as shown by the two-dot chain line in fig. 3, the electromagnets 44 are disposed at three positions corresponding to the one end portion 18B, the other end portion 18C, and the bent portion 18D of the main body portion 18. By disposing the plurality of electromagnets 44 at such positions, the body portion 18 mounted on the mounting surface 40 can be held on the mounting surface 40 by magnetic force without falling off from the mounting surface 40.

That is, the manufacturing apparatus 30 of the embodiment is an apparatus for forming the resin frame 14 in a posture in which the window glass 12 is arranged in the substantially vertical direction, as described above. Therefore, means for holding the body portion 18 on the mounting surface 40 without dropping from the mounting surface 40 is required, and as the means, the electromagnet 44 is used. In order to securely hold the body portion 18 on the mounting surface 40, the electromagnets 44 are disposed at the three positions described above, for example.

Next, the structure of the electromagnet 44 will be described with reference to fig. 5. In fig. 5, in order to explain the structure of the electromagnet 44, the scale of the other members is appropriately changed and shown, and therefore, the aspect ratio does not have to be the size shown in fig. 5.

The electromagnet 44 includes an iron core 48, a coil 50, a power source 52, and a switch 54. The core 48 has a cylindrical shape having at least a tip end surface 48A and an outer peripheral surface 48B, and the tip end surface 48A is disposed so as to face the back surface 46 of the first die 32.

The back surface 46 has a magnet support portion 56, and the magnet support portion 56 has a magnet mounting hole 58 into which the core 48 is inserted and which surrounds the outer peripheral surface 48B.

Further, a tube 60 made of a non-magnetic material is disposed in a gap between the magnet mounting hole 58 and the outer peripheral surface 48B. Thereby, magnetic force can be efficiently generated from the distal end surface 48A of the core 48. The tube 60 is an example of a cylindrical nonmagnetic body, and the same nonmagnetic body as the first mold 32 can be exemplified as the nonmagnetic body.

The coil 50 is wound around a cylindrical portion 48C constituting a base portion of the core 48, and is connected to a power source 52 through a switch 54. Therefore, when the switch 54 is turned on, a current flows from the power source 52 to the coil 50, and a magnetic force is generated in the core 48. The iron core 48 thus configured is attached to the magnet support portion 56 by bolts 62.

As described above, the manufacturing apparatus 30 of the embodiment includes the mold 36 having the electromagnet 44, but includes, as other apparatuses, for example, a conveying apparatus that conveys the lace 16 to the first mold 32, a moving apparatus that relatively moves the first mold 32 and the second mold 34 forward and backward in the horizontal direction, an injection apparatus that injects molten resin into the cavity space 38, and a carrying-out apparatus that carries out the window glass 10 with a resin frame from the first mold 32.

Next, a method for manufacturing the resin frame-equipped window glass 10 using the manufacturing apparatus 30 of the embodiment will be described.

First, the first mold 32 and the second mold 34 are disposed at positions relatively separated from each other in the horizontal direction indicated by an arrow a in fig. 5. At this position, as shown in fig. 4, the main body portion 18 of the lace 16 is mounted on the mounting surface 40 of the first mold 32. At this time, the switch 54 of the electromagnet 44 is in an off state, and the main body portion 18 is held at a position not deviated from the normal position with respect to the mounting surface 40 by the magnetic force of the electromagnet 44.

Next, when the main body 18 is mounted on the mounting surface 40 at the normal position, the switch 54 of the electromagnet 44 is turned on, and the magnetic force is generated in the core 48. Thereby, the main body 18 is held at the normal position of the mounting surface 40 by the magnetic force of the core 48.

Next, after the primer is applied to the peripheral edge portion 12A of the window glass 12, the peripheral edge portion 12A is attached to a predetermined position of the first mold (see fig. 5). Then, the first mold 32 and the second mold 34 are relatively moved forward in the horizontal direction indicated by an arrow a in fig. 5, and the first mold 32 and the second mold 34 are brought into contact with each other. Thereby, a cavity space 38 is formed between the first mold 32 and the second mold 34, and the cavity space 38 can house the lace 16 and the peripheral edge portion 12A of the window glass 12.

Next, a molten resin (not shown) is injected into the cavity space 38 from a resin injection port 64 indicated by a broken line provided in the second mold 34, and the cavity space 38 is filled with the molten resin. Then, the switch 54 of the electromagnet 44 is turned off, and the first mold 32 and the second mold 34 can be relatively moved backward in the horizontal direction indicated by the arrow a. Thereby, the window glass 10 with a resin frame shown in fig. 1 can be manufactured.

When the window glass 10 with a resin frame manufactured as described above is observed, the electromagnet 44 is not exposed from the mounting surface 40, and the electromagnet 44 is disposed with the first mold 32 as a non-magnetic body interposed therebetween, so that the decorated lace 16 does not contact the electromagnet 44, and a step does not occur in the first mold 32, so that a portion of the decorated lace 16 corresponding to the installation position of the electromagnet 44 is not scratched, and is not deformed, and no problem in quality is recognized. Therefore, according to the manufacturing apparatus 30 of the embodiment, the quality of the window glass 10 with a resin frame body provided with the decorative lace 16 made of a magnetic material can be improved.

In the embodiment, the manufacturing apparatus 30 in which the first die 32 and the second die 34 are relatively moved forward and backward in the horizontal direction is exemplified as an example of the manufacturing apparatus of the present invention, but the present invention is also applicable to a manufacturing apparatus in which the first die and the second die are relatively moved forward and backward in the vertical direction (hereinafter, also referred to as a manufacturing apparatus of another example). In the case of the manufacturing apparatus of another example, the window glass 12 may be disposed between the first mold and the second mold so that the main surface 12B thereof is in a substantially parallel direction with respect to the ground.

However, in the case of the manufacturing apparatus of the other example, since the projection area of the mold when the mold is projected on the floor is increased, the installation space of the manufacturing apparatus may be increased. In contrast, in the manufacturing apparatus 30 of the embodiment, the projected area of the mold 36 when projected on the floor surface is smaller than that of the manufacturing apparatuses of the other examples. Therefore, the manufacturing apparatus 30 of the embodiment is preferably used from the viewpoint of saving the installation space of the manufacturing apparatus.

Further, according to the manufacturing apparatus 30 of the embodiment, as shown in fig. 3, since a plurality of (3, as an example) electromagnets 44 are arranged at predetermined intervals in the longitudinal direction of the first mold 32, the lace 16 can be effectively held on the mounting surface 40. Further, by disposing the electromagnet 44 at the position shown in fig. 3 (the one end portion 18B, the other end portion 18C, and the bent portion 18D of the main body portion 18), the lace 16 can be more effectively held on the mounting surface 40.

Further, according to the manufacturing apparatus 30 of the embodiment, since the core 48 is inserted into the magnet mounting hole 58 of the magnet support portion 56 of the first mold 32, the front end surface 48A of the core 48 and the back surface 46 can be reliably arranged to face each other.

Further, according to the manufacturing apparatus 30 of the embodiment, since the tube 60 made of a non-magnetic material is disposed in the gap between the outer peripheral surface 48B of the core 48 and the magnet mounting hole 58, the magnetic force can be efficiently generated from the distal end surface 48A of the core 48.

In the manufacturing apparatus 30 of the embodiment, the electromagnet 44 is exemplified as the magnet, but a permanent magnet may be used instead of the electromagnet 44. However, it is preferable to use the electromagnet 44 as the magnet, which can be switched on and off, from the viewpoint of holding the main body portion 18 at a position not deviated from the normal position with respect to the mounting surface 40 by the magnetic force of the magnet.

While the embodiments of the present invention have been described above, the present invention is not limited to the above examples, and various improvements and modifications may be made without departing from the scope of the technical idea of the present invention.
