Description

  The present invention relates to a window assembly used by being attached to a window opening edge of a mounted body such as a vehicle, and a method for manufacturing the same. The present invention also relates to a manufacturing apparatus suitable for carrying out such a manufacturing method. Furthermore, it is related with the window plate for window assemblies suitable for the use which manufactures the said window assembly.

A window plate made of inorganic glass and a shielding member integrally fixed along the outer peripheral edge of the window plate (sometimes called a frame material, molding, gasket, etc. Hereinafter, these are collectively referred to as a “shielding member”. Is known). Such a window assembly is used by being attached to a window opening edge of a mounted body such as a vehicle or a building or a workpiece.

The shielding member of the window assembly according to the present invention is a molding in which at least a portion of the base that is in contact with the adhesive layer (portion joined to the window plate) is mainly composed of an olefin-based thermoplastic elastomer material or a styrene-based thermoplastic elastomer material. It is made of material.
Examples of the hard segment (olefin component) of the olefinic thermoplastic elastomer constituting such a molding material include polyethylene (PE), polypropylene (PP), and poly-1-pentene. Of these, polyethylene and polypropylene are preferred, and polypropylene is particularly preferred. Examples of the soft segment (elastomer component) of the olefinic thermoplastic elastomer include ethylene-propylene copolymer (EPM) and ethylene-propylene-diene copolymer (EPDM). Of these, EPDM is particularly preferred. Two or more types of polymers may be contained as the hard segment, and the same applies to the soft segment, but an olefin-based thermoplastic elastomer in which the hard segment is polypropylene and the soft segment is EPM or EPDM is particularly preferably used. . For example, 5 to 45 parts (more preferably 10 to 35 parts, more preferably 20 to 30 parts) of polypropylene, 20 to 60 parts (more preferably 30 to 50 parts) of EPDM, and an appropriate amount (by mass ratio) For example, a molding material formed by blending 20 to 50 parts, preferably 30 to 40 parts of a softener can be preferably used. Commercially available TPO that can be preferably used as a material for forming the base of the shielding member (at least the part in contact with the adhesive layer) includes “Santoprene (registered trademark)” available from AES Japan KK, Mitsui Chemicals, Inc. Examples thereof include “Miralastomer (registered trademark)” that can be obtained from a corporation and trademark “Thermo Run” that can be obtained from Mitsubishi Chemical Corporation.

  As the styrenic thermoplastic elastomer constituting the molding material, a styrene block copolymer (SBC) having a styrene block and an olefin block is preferable. For example, styrene-butadiene-styrene block copolymer (SBS), styrene-isoprene-styrene block copolymer (SIS), styrene-ethylene-butylene-styrene block copolymer (SEBS, hydrogenated SBS), styrene-ethylene. -Propylene-styrene block copolymer (SEPS, hydrogenated SIS) etc. can be used. As commercial products of SBC that can be preferably used as a material for forming the base part of the shielding member (at least the part in contact with the adhesive layer), a trademark “ACTIMER” available from RIKEN TECHNOS CORPORATION, a trademark available from APCO CORPORATION “Sumiflex”, “Lavalon (registered trademark)” available from Mitsubishi Chemical Corporation, and the like.

  The material which forms at least the part (base part) joined to the window plate in the shielding member can contain an organic or inorganic filler. It is preferable to use an inorganic filler. For example, calcium carbonate, calcium silicate, magnesium silicate, carbon black, talc, clay, kaolin, silica, diatomaceous earth, mica powder, alumina, barium sulfate, aluminum sulfate, calcium sulfate, basic magnesium carbonate, molybdenum disulfide, One or more particulate inorganic fillers selected from glass spheres, shirasu balloons, etc .; carbon fibers, glass fibers, alumina fibers, silicon carbide fibers, inorganic whiskers (eg basic magnesium sulfate whiskers, potassium titanates) Fibrous inorganic fillers such as inorganic fibers such as whiskers and aluminum borate whiskers) can be used. Among these, only 1 type may be used and 2 or more types may be used together. Such an inorganic filler can be contained, for example in the ratio which occupies 1-50 mass% of the whole.

  In addition, a part (for example, protrusion part) other than the location joined to a window board among shielding members may be formed with the molding material of the composition substantially the same as the above base molding materials, and molding of a different composition A material (for example, a molding material mainly composed of TPE other than TPO and TPS) may be used. For example, at least the protruding portion of the shielding member can be formed of a molding material (projecting portion molding material) that is softer than the base portion. In this case, as the protrusion molding material, a relatively soft thermoplastic elastomer (for example, TPO whose hard segment is an olefin resin such as polypropylene and whose soft segment is an ethylene-propylene-diene copolymer, A molding material mainly composed of a material having a soft segment ratio higher than that of the base material can be preferably used.

A decorative strip can be provided on the outer surface (typically the surface of the base) of the shielding member. Of the base part of the shielding member, it is preferable to dispose the decorative strip on the surface of the part that becomes the outside (for example, the outside of the vehicle) when attached to the mounted body. Thereby, the effect (decoration effect) by arrange | positioning a decoration strip can be exhibited especially well. As decorative strips, those composed of resin materials such as polyester and fluororesin, those composed of metal materials such as aluminum, chrome, and stainless steel, those composed of these composite materials, and lamination of these materials (For example, a laminate of a synthetic resin sheet and a metal foil) or the like can be used. It is possible to preferably use a decorative ornamental material formed into a long (strip shape, tape shape, etc.) decorative strip or rod shape made of such a material.
The shielding member in the present invention is formed as a shielding member alone in a separate process in advance (that is, before being joined to the window plate). Since the previously formed shielding member is used in this way, there is an advantage that the shielding member having a stable shape can be joined. The method for molding the shielding member is not particularly limited, and for example, an injection molding method, an extrusion molding method, or the like can be employed. The compound extrusion method is preferably used when a core material such as a glass fiber yarn for preventing expansion or contraction is embedded in the inside during extrusion molding or when a shielding member having a decorative strip on the surface is molded. It is done. It is preferable that the shielding member is long and the cross-sectional shape is constant by extrusion molding, and that the cross-sectional shape is changed by injection molding.

The adhesive layer is mainly composed of an acid-modified polyolefin resin or an acid-modified olefin-styrene copolymer resin. The polyolefin resin is a polyethylene resin, a polypropylene resin, a copolymer resin of ethylene and another α-olefin (one or more of propylene, 1-butene, 1-hexene, 4-methyl-1-pentene, etc.). , Copolymer resins of propylene and other α-olefins (one or more of 1-butene, 1-hexene, 4-methyl-1-pentene, etc.). The olefin-styrene copolymer resin includes an olefin monomer (ethylene, propylene, 1-butene, 1-hexene, 4-methyl-1-pentene, etc.) and a styrene monomer (styrene, α-methylstyrene, etc.).

The “resin” referred to herein may include those showing good rubber elasticity at room temperature.
Such a polyolefin resin or olefin-styrene copolymer resin is “acid-modified” means that an acidic group (typically a carboxyl group) is introduced. Such an acid-modified resin can be obtained, for example, by graft polymerization of an unsaturated carboxylic acid to the above-described polyolefin resin or olefin-styrene copolymer resin. As the unsaturated carboxylic acid, one or more of acrylic acid, methacrylic acid, crotonic acid, isocrotonic acid, maleic acid, fumaric acid, itaconic acid and the like can be used. Or you may use the unsaturated carboxylic acid derivative (ester, an anhydride, etc.) which can be converted into a carboxyl group by suitable post-processing (hydrolysis etc.). For example, an acrylic ester and / or a methacrylic ester can be graft polymerized and then the ester can be hydrolyzed to generate a carboxyl group.

Preferred acid-modified resins as the main component of the adhesive layer (adhesive) in the present invention include so-called carboxyl group-modified polyolefin resins, acrylic-modified polyolefin resins, carboxyl group-modified olefin-styrene copolymer resins, and acrylic-modified olefin-styrene copolymers. Resin is exemplified. Examples of commercially available materials that can be used for forming the adhesive layer include the trademark “Surflen (registered trademark)” available from Mitsubishi Chemical Corporation. For example, “Surflen (registered trademark) P-1000”, “Same A-1000”, “Same E-2000”, “Same AP-343” and the like can be used. In particular, “Surflen (registered trademark) P-1000”, “Same AP-343” and the like can be preferably used.
In addition, it is considered as follows as a theory which can obtain suitable adhesive force.
That is, in the case of adhesion between TPO and an acid-modified polyolefin resin adhesive, the adhesive and glass are bonded by hydrogen bonding or ester bonding between -H group in the adhesive and -OH group in glass activated by heating. And the olefin component in the adhesive and the olefin component (for example, PP component) in the shielding member are compatible with each other, thereby bonding the adhesive and the shielding member. Thereby, it is considered that the glass window plate and the shielding member using TPO are appropriately bonded.
Further, in the case of bonding between TPS and an acid-modified olefin-styrene copolymer resin adhesive, the adhesive is bonded by hydrogen bonding between -H group in the adhesive and -OH group in glass activated by heating. As the glass adheres, the olefin part in the adhesive and the olefin component in the shielding member are compatible with each other, thereby bonding the adhesive and the shielding member. Thereby, it is considered that the glass window plate and the shielding member using TPS are appropriately bonded.

  A preferred method of manufacturing the window assembly having such a configuration includes a step of preparing a window plate having both front and back surfaces and a shielding member pre-formed using a molding material mainly composed of TPO or TPS. Here, at least one member of the window plate and the shielding member is bonded to a portion to be joined to the other member, the main component being an acid-modified polyolefin resin or an acid-modified olefin-styrene copolymer resin. It has an agent layer. That is, this adhesive layer may be disposed on the window plate side, the shield member side, or both of these members, of the planned joining positions of the window plate and the shielding member. Good. Here, the “arrangement” is not limited to the case where the adhesive layer is bonded to the window plate or the shielding member, for example, when a sheet-like adhesive layer is placed on the surface of the window plate or the shielding member, etc. It is a concept that also includes

  The window assembly manufacturing method disclosed herein may include a step of holding the shielding member with a holding member. It is preferable to hold the shielding member in a state in which at least a portion to be joined to the window plate (a place to be joined) is exposed. This holding member can reversibly expand and contract. For example, an elastic material (preferably a material having airtightness and good rubber elasticity at normal temperature, such as EPDM, silicone rubber, latex, etc.) is used, and a cloth shape is used to improve durability. A holding member having a cavity in which fluid can be supplied and discharged from the inside can be preferably used. By supplying fluid (air, water, oil, etc.) from the outside to the cavity, the holding member can be expanded by the fluid pressure. With the expansion force of the holding member, the shielding member held by the holding member can be pressed against the outer peripheral edge of the window plate. Prior to this pressure contact, the shielding member and / or the adhesive layer disposed at the planned bonding position of the window plate is heated, so that the shielding member is pressed against the outer peripheral edge of the window plate and the adhesive layer is heated. A state can be realized. Moreover, you may implement | achieve the said state by heating an adhesive bond layer, after pressing a shielding member to the outer periphery of a window plate. Alternatively, the shielding member may be pressed against the outer peripheral edge of the window plate and the adhesive layer may be heated in parallel. Thereby, a window board and a shielding member can be joined with an appropriate adhesive force.

  The adhesive layer can be heated by directly heating the adhesive layer, such as a method of irradiating the adhesive layer with infrared rays or a method of blowing hot air on the adhesive layer. Moreover, the member (window plate and / or shielding member) on which the adhesive layer is disposed may be heated, and the adhesive layer may be indirectly heated by heat transfer from the member. As a method for heating the member on which the adhesive layer is disposed, the same heating method as that for directly heating the adhesive layer can be used. In particular, when the adhesive layer provided on the window plate side is heated, a method of heating the adhesive layer by heat transfer from the window plate can be preferably employed. Moreover, you may heat an adhesive bond layer by combined use of the said direct heating and indirect heating. Or you may heat the whole window panel in which the adhesive bond layer is arrange | positioned by oven etc. As shown in FIG.

Also, reference numeral 46 in FIG. 2 indicates a dam rubber that suppresses the sealant 44 from protruding.

The window assembly 1 configured as described above can be manufactured using, for example, a window assembly manufacturing apparatus 50 configured as shown in FIG.
The device 50 is arranged so as to approach and separate from the window plate holding device 60, the window plate holding device 60 that holds the window plate 10, the shielding member holding device 70 that holds the shielding member 20, and the window plate holding device 60. And a cylinder (shielding member holding device moving means) 52 for moving the shielding member holding device 70. Further, heating that can heat the adhesive layer 30 of the window plate 10 held by the window plate holding device 60 and / or the adhesive layer 30 of the shielding member 20 held by the shielding member holding device 70 by irradiation with light (infrared rays). A device 54 is provided.
The window plate holding device 60 has a sucker-like window plate surface holding portion 642 near the tip of the robot hand 64. The window plate 10 can be held in the window plate holding device 60 by the window plate surface holding portion 642 adsorbing the central portion of the surface 10A of the window plate 10. The hand 64 is connected to the window plate holding device main body through an arm (not shown). The window plate holding device 60 moves the hand 64 and the arm (including rotational movement) to move the window plate 10 held by the window plate surface holding portion 642 in the X direction shown in FIG. 3 (the window plate 10 holds the shielding member). The apparatus 70 is configured to be movable in a direction approaching and separating from the device 70 (left and right direction in FIG. 3) and θ direction (rotation direction).

  The shielding member holding device 70 includes a holding member 72 that is a long member that can be elastically deformed and that has a cavity 73 extending in the longitudinal direction thereof. The holding member 72 holds the back side of the portion to be joined (planned joining location) over the entire length of the shielding member 20 in a state where the portion to be joined to the window plate 10 in the base portion 22 of the shielding member 20 is exposed. Can do. At this time, by holding the protruding portion 24 of the shielding member 20 in a state of being fitted in the concave portion 72A of the holding member 72, the displacement of the shielding member 20 during joining can be well prevented during the movement described later. In the example shown in FIG. 3, the cavity 73 is divided into a first cavity 732 located below the recess 72A and a second cavity 734 located above the recess 72A. These cavities 732 and 734 may be in communication or may be blocked. The cavity 73 is connected to a compressor (compressed air supply source) 782 that supplies air to the cavity 73 via a fluid (here, compressed air) supply means 78. One end of an air circulation pipe 784 constituting the fluid supply means 78 is branched, one branch pipe is connected to the compressor 782 via an air introduction valve 786, and the other branch pipe is connected to the atmosphere via an air discharge valve 787. It has been released. Further, the other end of the air circulation pipe 784 branches and is connected to each of the cavities 732 and 734.

  The shielding member holding device 70 includes a support member 74 that is made of a rigid body and supports the back side of the holding member 72 over its entire length. The support member 74 is formed with a recess 74 </ b> A extending in the longitudinal direction corresponding to the shape of the holding member 72. By fitting and fixing the holding member 72 in the recess 74A, the back side of the holding member 72 can be supported while the side in contact with the shielding member 20 is exposed. By supporting the back surface side of the holding member 72 in this way, the expansion of the holding member 72 to the back surface side is prevented. Accordingly, the holding member 72 can be efficiently expanded and protruded (expanded) toward the outer peripheral end 100 of the window plate 10 by the pressure of the fluid supplied to the cavity 73. An infrared shielding device 76 is provided above the shielding member holding device 70. The infrared shielding device 76 is attached to the upper end of the support member 74 by a hinge 764, and includes a shielding body 762 that can rotate around the hinge 764. By lowering the shield 762 (arranged at the position indicated by the solid line in FIG. 3), the shield member 20 set on the shield member holding device 70 is substantially shielded from infrared rays irradiated by the heating device 54 described later. can do. In addition, since the upper end of the support member 74 is covered with the shield 762, the temperature rise of the support member 74 due to infrared irradiation can be suppressed, and the support member 74 can be prevented from being deteriorated, deformed, or different in color. . As shown in FIG. 3, the effect of suppressing the temperature increase can be exhibited better by adopting a configuration in which a slight gap is provided between the shield 762 and the support member 74.

  The heating device 54 is a device that emits infrared rays, and as shown in FIGS. 3 and 5, a light emitting unit 55 having an infrared lamp 552 and a reflecting plate 554 as a light emitting source, and light emission that moves the light emitting unit 55. Part moving means 56. The light emitting unit moving unit 56 includes an X direction moving unit 57 and a Y direction moving unit 58 in a direction orthogonal to the X direction. The moving unit 57, 58 moves the light emitting unit 55 in the X direction and the Y direction. Configured to get. The X-direction moving means 57 includes an elongated X-direction moving support member 572, an X-direction moving ball screw 574 that passes through the support member 572, and an X-direction moving servo motor 578 connected to one end of the ball screw 574. Prepare. The X-direction movement support member 572 is formed with an X-direction slide guide 576 that is slidably fitted in an X-direction guide groove 563 provided in the attachment member 562. When the screw rod of the ball screw 574 is rotated in the α direction by driving the servo motor 578, the X-direction moving support member 572 is slid along the guide groove 563 in the longitudinal direction of the ball screw 574 (X direction, left-right direction in FIG. 3). Can be made. The Y-direction moving means 58 includes a Y-direction moving support member 582 that fixes the heating means 55, a Y-direction moving ball screw 584 that passes through the support member 582, and a Y-direction moving servo connected to one end of the ball screw 584.

The Y-direction movement support member 582 is formed with a Y-direction slide guide 586 that slidably engages with a Y-direction guide groove 573 provided in the longitudinal direction on the X-direction movement support member 572. When the screw rod of the ball screw 584 is rotated in the β direction by driving the servo motor 588, the Y-direction moving support member 582 is moved along the guide groove 573 in the longitudinal direction of the ball screw 584 (Y direction on the paper surface of FIGS. 4 and 5). It can be slid in the horizontal direction. Although illustration is omitted, when the window plate 10 is greatly bent, the light-emitting portion moving means 56 may be further added with a Z-direction moving means in a direction orthogonal to the X direction and the Y direction. .

The window assembly manufacturing apparatus 50 having such a configuration, the window plate 10 having the end face 10C roughened by the grinding process and the frit layer 12, and the long shielding member 20 extruded into the cross-sectional shape shown in FIG. The window assembly 1 can be manufactured by using, for example, the following procedure.
Step 1: A step of degreasing the outer peripheral edge of the window plate. That is, at least a range in which the adhesive layer 30 is provided on the outer peripheral edge of the window plate 10 is cleaned (degreased). For example, wipe with a lower alcohol. This removes oil, dust, dirt, and the like.
Step 2: This is a step of forming an adhesive layer. That is, the adhesive layer 30 is formed on the cleaned outer peripheral edge. For example, an adhesive in which an acid-modified polypropylene resin is dissolved or dispersed in an appropriate solvent (such as one containing toluene as a main component) is applied to a predetermined range of the window plate 10 (a portion where the shielding member 20 is provided later), a brush, Apply using. At this time, the adhesive layer 30 is firmly bonded to the outer peripheral edge 100 of the window plate 10 by the anchor effect on the roughened surfaces of the frit layer 12 and the end face 10C.
Step 3: A step of drying the adhesive layer. That is, the adhesive layer (applied adhesive) 30 is dried (preferably naturally dried) to volatilize at least a part (preferably most) of the solvent contained in the adhesive. By this step 3, the window plate 10 for window assemblies for manufacturing the window assembly 1 according to the present embodiment is obtained. That is, the window assembly 1 in which a long shielding member 20 mainly composed of TPO that shields between the window plate periphery and the window opening edge along the outer periphery 100 of the inorganic glass window plate 10 is integrally provided. The window plate 10 for a window assembly for manufacturing the window assembly 10 is provided with an adhesive layer 30 mainly composed of an acid-modified polyolefin resin formed in a portion where the shielding member 20 is provided. can get.

  Step 4: This is a step of setting the window plate to the window plate holding device. That is, as shown in FIG. 3, a suction cup-like window plate surface holding portion 642 provided in the hand 64 of the window plate holding device 60 is vacuumed at the center of the surface 10A of the window plate (window assembly window plate) 10. Adsorb. Then, by appropriately controlling the operation of the window plate holding device 60, the window plate 10 is placed on the window plate set base 66 and held in that position. At this stage, as shown in FIG. 4, the shielding member holding device 70 is located on the plus side in the X direction with respect to the outer peripheral edge 100 of the window plate 10 (upward on the plane of FIG. 4, FIG. 3). On the right). In addition, in order to make a figure legible, in FIG. 4, illustration of the window plate holding | maintenance apparatus 60, the heating apparatus 54, and the shielding apparatus 76 is abbreviate | omitted.

Step 5: This is a step of setting the shielding member to the shielding member holding device. In other words, the protrusion 24 of the shielding member 20 that has been extruded in advance is fitted into the recess 72 </ b> A of the holding member 72, and the shielding member 20 is held by the holding member 72. At this time, the air discharge valve 787 of the fluid supply means 78 connected to the cavity 73 is opened, and the cavity 73 of the holding member 72 is almost at atmospheric pressure. Next, the shield 762 of the infrared shielding device 76 is lowered.
In addition, the context before and after Step 4 and Step 5 is not particularly limited. Step 4 and step 5 may be performed in parallel. Further, the timing of lowering the shield 762 of the infrared shielding device 76 is not limited to step 5, but from the time when the shielding member 20 is set to the holding member 72 of the shielding member holding device 70 until the start of infrared irradiation. It may be between. Further, when the operation of setting the shielding member 20 on the holding member 72 is not hindered, the shielding member 20 may be set on the holding member 72 with the shielding body 762 lowered.

  Step 6: This is a step of arranging the outer peripheral edge of the window plate and the shielding member in close proximity. That is, the shielding member holding device 70 in a state where the shielding member 20 is held by the operation of the cylinder 52 is moved to the minus side in the X direction shown in FIGS. 3 and 4 (on the left side in FIG. 3 and the lower side in FIG. 4). Move. Thus, by moving the shielding member holding device 70 forward to the window plate 10 side, the outer peripheral edge portion 100 of the window plate 10 and the shielding member 20 are brought close to each other. For example, it is preferable that the outer peripheral edge portion 100 (adhesive layer 30) of the window plate 10 and the shielding member 20 are close enough to contact each other. There may be a slight gap between the outer peripheral edge 100 of the window plate 10 and the shielding member 20. Alternatively, the window plate 10 (adhesive layer 30) and the shielding member 20 may be brought close to each other so that the shielding member 20 is lightly pressed against the outer peripheral edge portion 100 of the window plate 10. In FIG. 4, the position (corresponding to the position shown in FIG. 3) of the shielding member holding device 70 after the forward movement is indicated by a two-dot chain line.

  Step 7: This is a step of expanding the holding member and pressing the shielding member against the outer peripheral edge of the window plate. That is, the air discharge valve 787 is closed and the air introduction valve 786 is opened, and the compressor 782 is operated to supply compressed air to the cavity 73. As a result, the internal pressure of the cavity 73 increases, and the holding member 72 expands due to the air pressure (fluid pressure). Here, since the expansion of the holding member 72 to the back side is blocked by the support member 74, the holding member 72 mainly bulges toward the back surface 10 </ b> B and the end surface 10 </ b> C side of the window plate 10. Due to the expansion of the holding member 72, the shielding member 20 held by the holding member 72 is pressed against the frit layer 12 and the end surface 10C (adhesive layer 30) of the outer peripheral edge portion 100 of the window plate 10 with a uniform pressure peculiar to the fluid pressure. Is done. Furthermore, even if a slight gap is generated between the surface of the outer peripheral edge 100 of the window plate 10 and the shielding member 20, the shielding member 20 is bent by the fluid pressure of the holding member 72 and closely contacts the surface of the outer peripheral edge 100.

  Step 8: This is a step of heating the adhesive layer. That is, the infrared rays emitted from the infrared lamp 552 of the heating device 54 are condensed by the reflecting plate 554 and irradiated to the outer peripheral edge portion 100 of the window plate 10, so that the window plate 10 on which the adhesive layer 30 is formed is at least Heating is performed so that the outer peripheral edge portion 100 has a temperature range exceeding normal temperature (for example, 25 ° C.). Thus, the adhesive layer 30 can be heated mainly by heat transfer and radiation from the window plate 10. The temperature range suitable for the heating temperature of the outer peripheral edge portion 100 of the window plate 10 at this time (the adhesive layer 30 is heated to a temperature range approximately equal to this heating temperature) constitutes the adhesive layer 30. Although it depends on the type of adhesive, etc., for example, it can be in a temperature range above 30 ° C. and below 230 ° C. The range is preferably about 50 ° C. or higher (typically about 50 to 130 ° C.), more preferably about 60 ° C. or higher (typically about 60 to 120 ° C.), and about 80 ° C. or higher ( More preferably, it is typically about 80 to 120 ° C. The heating device 54 moves the light emitting unit 55 to an appropriate position along the desired locus by controlling the light emitting unit moving means 56 (mainly, the X direction moving means 57 in this embodiment) (in this embodiment). The adhesive layer 30 is arranged so that the adhesive layer 30 can be efficiently heated to a uniform temperature by being moved substantially parallel to the upper end surface 10C of the window plate 10 while maintaining a certain distance. Further, when the infrared lamp 552 and the heated portion (adhesive layer 30) are largely separated in the Z direction during the movement and proper heating cannot be obtained, the above Z direction moving means can be used. As a result, both the state where the adhesive layer 30 is heated and the state where the shielding member 20 is pressed against the outer peripheral edge portion 100 (adhesive layer 30) of the window plate 10 are realized. As a result, the shielding member 20 is firmly bonded to the outer peripheral edge portion 100 of the window plate 10 via the adhesive layer 30.

Step 9: This is a step of contracting the holding member. That is, after stopping the heating, the shielding member 20 is cooled while being pressed against the window plate 10 for a predetermined time, and then the compressor 782 is stopped (or the air introduction valve 786 is closed) and the air discharge valve 787 is opened. As a result, the internal pressure of the cavity 73 of the holding member 72 is released, and the holding member 72 contracts. When the shielding member holding device 70 is moved to the plus side in the X direction by the operation of the cylinder 52, the shielding member 20 joined to the window plate 10 via the adhesive layer 30 is detached from the holding member 72 and moved to the window plate 10 side. Remain. Thus, the window assembly 1 in which the shielding member 20 is integrally joined to the outer peripheral edge portion 100 of the window plate 10 can be obtained.
Manufacturing steps other than steps 1 to 9 can be added to the manufacturing method exemplified here as necessary. Moreover, you may abbreviate | omit or merge one or more steps among steps 1-9 with other steps. For example, the adhesive layer 30 may be formed on the shielding member 20 side instead of being formed on the periphery of the window plate 10, or may be formed on both the window plate 10 and the shielding member 20.
The shielding member 20 is applied to the outer peripheral edge portion 100 of the window plate 10 by using the pressure (uniform pressure throughout the entire area) peculiar to the fluid (here, compressed air) supplied to the cavity 73 of the holding member 72 as in the above manufacturing method. Even if there is a variation in the outer shape of the window plate 10 due to the pressure contact, the holding member 72 expands following the variation, absorbs this, and presses the shielding member 20 uniformly and stably. 10 can be firmly bonded.

In the above embodiment, a window assembly including a shielding member mainly composed of TPO has been described. However, the present invention can also be applied to a window assembly including a shielding member mainly composed of TPS (preferably SBC). In this case, it is preferable to use an adhesive layer mainly composed of an acid-modified olefin-styrene copolymer resin as the adhesive layer.
Moreover, in the said Example, although the adhesive bond layer 30 is provided only in the range to which the shielding member 20 (base 22) is joined, the range which provides the adhesive bond layer 30 is not limited to this. For example, particularly on the surface 10B side of the window plate 10, the adhesive layer 30 may be provided in a slightly wider range including the above range in consideration of manufacturing errors. Or you may provide the adhesive bond layer 30 in a part of said range. Further, as in the above embodiment, the adhesive layer 30 may be provided continuously in the longitudinal direction, or may be provided intermittently (for example, in a stripe shape).
Further, in the above-described embodiment, the window plate 10 is held at a certain position, and the shielding member holding device 70 is moved with respect to the window plate 10 to press the shielding member 20 against the outer peripheral edge 100 of the window plate 10. However, the position of the shielding member holding device 70 may be fixed, and the window plate 10 may be moved with respect to the shielding member holding device 70. Alternatively, both the window plate 10 and the shielding member holding device 70 may be moved. Further, depending on the shape, type and production amount of the window assembly, the heating device 54 may be held and moved by the hand of a robot capable of teaching control (typically an articulated robot). In this case, it is particularly suitable for small- to medium-volume production of various varieties. Needless to say, when the heating device 54 is provided over the entire area to be heated, the moving means can be omitted.

<Second Example>
The second embodiment is an example in which the shape and configuration of the shielding member is different from the first embodiment. Hereinafter, members having the same functions as those according to the first embodiment are denoted by the same reference numerals, and description thereof is omitted.
As shown in FIG. 6, in the window assembly 2 according to the present embodiment, the outer surface 10 </ b> A of the window plate 10 and the outer surface of the shielding member 20 form a substantially flush surface. An adhesive layer 30 is formed on the outer peripheral edge portion 100 of the window plate 10 in a range from the back surface 10B of the window plate 10 to the chamfer 10D (edge on the front surface 10A side of the window plate 10) beyond the end surface 10C. The base 22 of the shielding member 20 is joined to the window plate 10 via the adhesive layer 30. On the surface of the base portion 22 on the side of the window plate surface 10 </ b> A, decorative strips 28 are continuously arranged along the longitudinal direction of the shielding member 20. The decorative strip 28 is a decorative tape formed in a plate shape having a C-shaped cross section. The shielding member 20 having such a configuration, for example, presses the decorative strip 28 against the surface of the base 22 on the window plate surface 10A side when the extruded base 22 is solidified but kept in a relatively soft state. And obtained by joining. Alternatively, the decorative strip 28 can be continuously supplied from the back side of the extrusion die (not shown) or from an intermediate position of the extrusion die and integrated with the surface of the shielding member in the extrusion die.
The window assembly 2 including such a shielding member 20 can be manufactured in the same procedure using, for example, the same window assembly manufacturing apparatus 50 (see FIG. 3) as in the first embodiment. In this embodiment, since the base portion 22 of the shielding member 20 is also joined to the chamfer 10D, the chamfer 10D has been described in relation to the frit layer 12 in the first embodiment when the chamfer 10D is roughened by grinding or the like. Due to the anchor action similar to the above, the end face 10C and the chamfer 10D have the effect of improving the adhesive strength.

Furthermore, although the manufacturing method of the back window of the vehicle has been exemplified in the first embodiment, the present invention can also be applied to the front window of the vehicle. In this case, when the window plate 10 is a laminated glass having the transparent intermediate film 10E as in the window assembly 3 shown in FIG. 7, the maximum temperature when the window plate 10 is heated is limited to about 110 ° C. It is preferable to prevent thermal degradation. In addition, the projecting portion of the shielding member may be formed into a substantially bowl shape and engaged with the window opening edge to fix the window assembly to the mounted body. In addition to the above, shapes having additional functions are also included in the concept of “protrusions” of the present application.
