Description

  The present invention relates to a method for forming a terminal part of a glazing channel for a multi-layer glass and a terminal part forming jig, and more particularly, a starting end of a glazing channel made of a thermoplastic resin material applied along the peripheral edge of a multi-layer glass. This invention relates to a method for forming a terminal portion of a glazing channel for a multi-layer glass capable of smoothly and beautifully forming a terminal connection portion at the end, and a forming jig used for the forming method.

  Conventionally, as shown in FIGS. 3 to 5, in a case where a double-glazed glass 5 is mounted on a sash frame 1 having a concave cross section constituting a window frame made of aluminum or the like, as shown in FIGS. A space layer 4 is formed between a plurality of glass plates 2a and 2b via a spacer 3 made of a primary sealing material 3a and a secondary sealing material 3b made of a rubber-like elastic body, and a spacer member 3c, and further a multilayer glass. 5 is a glazing channel 6 (sealing frame made of a thermoplastic resin material) that is extruded into an irregular cross section having a concave cross section for the purpose of watertightness and airtightness in the gap between the sash frame 1 and the multilayer glass 5. A method of fitting and mounting the multi-layer glass 5 mounted with the glazing channel 6 with a setting block 7 interposed on the bottom surface portion of the sash frame 1 is known (for example, see Patent Document 1).

  The glazing channel 6 as described above is used by cutting a molded product obtained by extruding a thermoplastic resin material into an irregular cross section by an extrusion molding machine into a size along each window frame, and in recent years an extrusion molding machine. The one that directly applies the glazing channel 6 extruded from the glass surface to the glass surface has been proposed (see, for example, Patent Document 2), and automation of the production line of the multilayer glass has been attempted.

By the way, in the conventional method of attaching or applying the glazing channel to the glass surface of the multi-layer glass, there is no particular consideration for the treatment of the end portion of the glazing channel and the end of the multi-layer glass. At the time of manufacturing the glass unit, it was necessary to prepare manual work such as cutting and pasting by an operator, or preparing a pre-formed material or gaskets. In addition, since the processing method is simply to cut and paste a pre-formed glazing channel on the applied glazing channel, the joint portion is not physically sealed, and the joint portion has a step or a gap. There is a problem that the appearance cannot be kept good because it is likely to occur and dust easily accumulates on the portion.

Inside the tool body 11, heating means 13 that can be heated to a predetermined temperature for plasticizing and welding the applied glazing channel 6 and the terminal connection part of the formed glazing channel 6 are cooled to a predetermined temperature and solidified. Cooling means 14 is provided.

  As the heating means 13, in this embodiment, a cartridge heater or an induction heater is provided along the corner terminal connecting portion 6a, and the temperature control uses a thermocouple 13a. The heating means 13 is controlled to a temperature (for example, around 180 ° C.) at which the applied material (thermoplastic resin material) of the glazing channel 6 is sufficiently plasticized.

  The cooling means 14 is constituted by a piping path 14a through which a cooling medium (for example, cold water) flows along the terminal connection portion 6a at the corner of the glazing channel 6, and the glazing channel 6 is cooled and solidified. In addition, a cooling medium is passed through the piping path 14a in order to cool the forming jig body 11 to a temperature having a sufficient strength at which the material of the glazing channel 6 does not deform, for example, 130 ° C., during the peeling process of the forming jig body 11.

  Then, after applying a glazing channel having a predetermined cross-sectional shape made of a thermoplastic resin material to the peripheral edge portion of the multilayer glass, a terminal portion at the start and end of the glazing channel 6, in this embodiment, a corner terminal connection The glazing channel is plasticized and welded by pressing the substantially L-shaped concave groove 12 of the forming jig body 11 previously heated to a predetermined temperature to the portion 6a through a pressing means (not shown) such as an air cylinder. Thereby, the terminal connection part of the glazing channel 6 without the joint part of a joint part and a clearance gap part is shape | molded.

  Thereafter, a valve (not shown) of the cooling means 14 of the forming jig body 11 is opened, and the shape is set by cooling the surface temperature of the forming jig body 11 to 130 ° C. through a cooling medium through the piping path 14a. The cooling time is not particularly limited, but the opening time of a valve (not shown) of the cooling means 14 is set by a timer, and when the shape is completed, the forming jig body 11 is pulled away from the corner terminal connection portion 6a of the glazing channel 6 and removed. The work is finished.

  The above-described operation method can be similarly implemented in the straight line terminal connection portion of the glazing channel 6.

  The operation operation of the above-mentioned method for forming the terminal portion of the glazing channel for double-glazed glass is controlled using a sequencer so as to be compatible with double-glazed glass of all thicknesses, and the setting and taking-out of the forming jig main body 11 are performed. Considering that this work does not require manual work by operating in a semi-automatic operation performed by a worker. In addition, the amount of application at the start point and the end point is controlled at the time of control in automatic application so as not to generate glazing channel overflow due to melting as much as possible. For the overflow that occurs at the minimum, the design of the mold (molding jig body 11) that flows along the glass corner surface is considered.

  By forming the terminal part of the glazing channel 6 by the method as described above, when the glazing channel 6 is directly applied to the glass surface, there is no connection between the terminal part of the glazing channel 6 at the start and end. The terminal connection part can be molded, and the appearance is good, and a shape that does not accumulate dust or dust can be molded integrally.
