Abstract

<P>PROBLEM TO BE SOLVED: To provide a manufacturing apparatus for a frame-provided glass which can at an early stage and certainly sense the breakage of glass. <P>SOLUTION: A rod supported by a cylinder is installed on the convex surface side of a curved plate glass, and on the glass surface of the opposite side to the glass surface on which the rod contacts there are installed sucking pads for holding the glass and a pressure sensor for sensing the pressure change of the sucking pads. The plate glass is held between a fixed mold and a movable mold, a cavity is formed in the peripheral part of the plate glass and a resin is injected into the cavity to form the frame. When the frame is formed by injection molding in the peripheral part of the glass, it sometimes happens that a large load is applied to the glass and causes the glass to be broken. Since the time for injecting the molten resin into the cavity of the mold which forms the frame is a short time, or below several seconds, it is favorable if the sensing of the breakage of the glass is conducted as early as possible. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

本発明は、車両や建物の開口部に用いられる樹脂枠体付き板ガラスの製造装置に関する。特に、樹脂枠体が湾曲した板ガラスの周辺部に射出成形され、射出成型用の金型に、湾曲した板ガラスの割れを検知するセンサを設けている製造装置に関する。   The present invention relates to an apparatus for manufacturing a plate glass with a resin frame used in an opening of a vehicle or a building. In particular, the present invention relates to a manufacturing apparatus in which a resin frame is injection-molded around a curved plate glass and a sensor for detecting cracks in the curved plate glass is provided in an injection mold.

板ガラスの周辺部に樹脂枠体を射出成形する装置において、樹脂枠体の射出成形は、固定型と移動型との間に板ガラスを保持し、該板ガラスの周辺部にキャビティが形成され、該キャビティに樹脂が射出されて、枠体が成形される。   In an apparatus for injection molding a resin frame on the periphery of a plate glass, the resin frame is injection molded by holding a plate glass between a fixed mold and a movable mold, and forming a cavity in the periphery of the plate glass. Resin is injected into the frame to form a frame.

射出成形の最中には、金型によって板ガラスは押さえつけられており、さらに板ガラスの周辺部に射出される樹脂によって、板ガラスに力が加わるため、板ガラスに複雑な応力が発生し、板ガラスが破損することがある。   During the injection molding, the plate glass is pressed by the mold, and the resin is injected into the periphery of the plate glass. A force is applied to the plate glass, which causes complex stress on the plate glass and breaks the plate glass. Sometimes.

板ガラスは、金型に覆われているため、板ガラスの破損を視認することができず、板ガラスの破損を検知しない場合は、生産性が悪いばかりか、射出成形を続行すると割れた板ガラスが金型を傷つけてしまって、金型が使用できなくなる恐れがある。   Since the plate glass is covered with a mold, it is not possible to visually recognize the breakage of the plate glass.If the breakage of the plate glass is not detected, not only the productivity is bad, but if the injection molding is continued, the broken plate glass will die. Otherwise, the mold may not be usable.

従って、射出成形中に板ガラスが割れた場合、直ちに板ガラスの割れを検知し、射出成形をやめる必要がある。   Therefore, when the plate glass breaks during the injection molding, it is necessary to immediately detect the crack of the plate glass and stop the injection molding.

板ガラスの割れを検知する方法として、特許文献１には、窓枠ゴムをガラス製窓板の周辺に成形する金型において、ガラスに当接する押し圧ピンと押し圧ピン位置センサとからなるガラス板の割れ検知手段が記載されており、押し圧ピンをガラス板に押し圧する手段として、コイルバネが開示されて、押し圧ピンがガラスを突き出たときに破損が検知される。   As a method for detecting cracks in a plate glass, Patent Document 1 discloses a glass plate composed of a pressure pin and a pressure pin position sensor that are in contact with glass in a mold for molding window frame rubber around a glass window plate. A crack detection means is described, and a coil spring is disclosed as means for pressing the pressing pin against the glass plate, and breakage is detected when the pressing pin protrudes from the glass.

また、特許文献２には、センサーピンがガラスを突き抜けることにより、破損の検知をすることが開示されている。   Patent Document 2 discloses that a sensor pin detects breakage by penetrating glass.

また、特許文献３には、真空ポンプに繋がるバキュウームカップを負圧にし、ガラスを金型に圧接させる装置において、バキュームカップと真空ポンプとをつなぐ負圧通路に、圧力ゲージに繋がる負圧通路を設け、圧力ゲージでガラスの破損を検知する成形装置が開示されている。
特開昭６３−１２２５０９号公報 特開平３−２３４６０８号公報 実開平１−１０６２１１号公報 Patent Document 3 discloses a negative pressure passage connected to a pressure gauge in a negative pressure passage connecting a vacuum cup and a vacuum pump in a device in which a vacuum cup connected to a vacuum pump has a negative pressure and glass is pressed against a mold. And a molding apparatus for detecting breakage of glass with a pressure gauge is disclosed.

ガラス周辺部に射出成形で枠体を成形する場合、枠体を形成する金型のキャビティに溶融樹脂を射出する時間は数秒以下と短時間で終了するので、ガラスの破損の検知はなるべく早いほうが良い。   When molding a frame around the glass by injection molding, the time for injecting the molten resin into the mold cavity forming the frame ends in a few seconds or less, so the glass breakage should be detected as soon as possible. good.

本願発明は、ガラスの破損を早期にしかも確実検知することが可能な、枠体付きガラスの製造装置を提供することを課題とする。   This invention makes it a subject to provide the manufacturing apparatus of glass with a frame which can detect damage of glass early and reliably.

本発明の枠体付きガラスの製造装置は、湾曲した板ガラスを金型に保持し、樹脂を該湾曲した板ガラスの周辺部に射出成形により一体成形する枠体付きガラスの製造装置において、シリンダーで支持されたロッドが湾曲した板ガラスの凸面側に設けられていることを特徴とする枠体付き板ガラスの製造装置である。   The apparatus for producing glass with a frame according to the present invention is supported by a cylinder in the apparatus for producing glass with a frame by holding a curved plate glass in a mold and integrally molding resin around the curved plate glass by injection molding. It is a manufacturing apparatus of plate glass with a frame, wherein the rod is provided on the convex surface side of the curved plate glass.

また、本発明の枠体付きガラス製造装置は、前記枠体付きガラス製造装置において、ロッドが接触するガラス面の反対側ガラス面に、ガラスを保持するための吸引パッドと、吸引パッドの圧力変化を検知する圧力検知器とが設けられていることを特徴とする枠体付きガラスの製造装置である。   Moreover, the glass manufacturing apparatus with a frame of the present invention is the glass manufacturing apparatus with a frame, in the glass manufacturing apparatus with a frame, a suction pad for holding the glass on the glass surface opposite to the glass surface in contact with the rod, and the pressure change of the suction pad And a pressure detector for detecting a glass frame-equipped manufacturing apparatus.

本発明の枠体付きガラスの製造装置は、流動性の高温高圧樹脂を金型に射出して、ガラスの周辺に枠体を射出成形する製造装置において、ガラスの破損を早期に検知する手段を提供することを可能にした。   The manufacturing apparatus for glass with a frame of the present invention is a manufacturing apparatus for injecting a flowable high-temperature and high-pressure resin into a mold and injection-molding the frame around the glass, and means for early detection of glass breakage. Made it possible to provide.

図を用いて、本発明の枠体付きガラス製造装置を説明する。   The glass manufacturing apparatus with a frame of the present invention will be described with reference to the drawings.

図１に示すように、枠体を形成する湾曲した板ガラス３を挟んで、上金型１と下金型２とを重ね、上金型と下金型とで、ガラス３の周辺部にキャビティ４、５を形成する。
キャビティ４、５に流動性の樹脂が、図示しない樹脂射出装置と金型に設けられているランナーを通して射出される。なお、上金型１は移動型、下金型は固定型と呼ばれることもある。 As shown in FIG. 1, an upper mold 1 and a lower mold 2 are stacked with a curved plate glass 3 forming a frame interposed therebetween, and a cavity is formed in the periphery of the glass 3 with the upper mold and the lower mold. 4 and 5 are formed.
A fluid resin is injected into the cavities 4 and 5 through a resin injection device (not shown) and a runner provided in the mold. The upper mold 1 is sometimes called a movable mold, and the lower mold is sometimes called a fixed mold.

湾曲した板ガラス３の凸面側のガラス面に、シリンダー６のロッド７を押し当て、ロッド７の位置の変化を検知して、湾曲した板ガラス３の破損を検知する。   The rod 7 of the cylinder 6 is pressed against the glass surface on the convex surface side of the curved plate glass 3 to detect a change in the position of the rod 7 to detect breakage of the curved plate glass 3.

シリンダー６には、位置検出器付きシリンダーを用いることが好ましい。位置検出器付きシリンダーを用いないで、ロッド７が変位したかどうかを、光学的あるいは機械的に検知してもよい。   The cylinder 6 is preferably a cylinder with a position detector. Whether or not the rod 7 has been displaced may be detected optically or mechanically without using a cylinder with a position detector.

ロッド７を湾曲した板ガラス３の凸面に接触させて破損を検知するのは、湾曲した板ガラス３が割れたとき、凸面側のほうが凹面よりも破損したとこの変位が大きく出やすい傾向があるためである。   The reason why the rod 7 is brought into contact with the convex surface of the curved plate glass 3 to detect the breakage is that when the curved plate glass 3 is broken, if the convex side is broken more than the concave surface, this displacement tends to be large. is there.

さらに、湾曲した板ガラス３の凹面側を吸引パッド８、９で吸引して保持しておくと、湾曲した板ガラス３の破損時の変位がより早く検知できるので好ましい。   Furthermore, it is preferable to suck and hold the concave surface side of the curved plate glass 3 with the suction pads 8 and 9 because the displacement at the time of breakage of the curved plate glass 3 can be detected earlier.

また、吸引パッド８、９で湾曲した板ガラス３を吸引して保持いている時、すなわち、開閉弁１２、１４は閉、開閉弁１３は開の状態で、真空ポンプ１０を作動させて、吸引パッド８、９で湾曲した板ガラス３を吸引している状態で、配管１５に圧力センサ１１を連結して、湾曲した板ガラスの破損が、該圧力センサ１１の圧力変化として検知されることが好ましい。圧力センサ１１には、圧力計や圧力トランスデューサが好適に用いられる。   Further, when the curved glass plate 3 is sucked and held by the suction pads 8 and 9, that is, the on-off valves 12 and 14 are closed and the on-off valve 13 is opened, the vacuum pump 10 is operated to It is preferable that the pressure sensor 11 is connected to the pipe 15 in a state where the curved plate glass 3 is sucked at 8 and 9, and breakage of the curved plate glass is detected as a pressure change of the pressure sensor 11. A pressure gauge or a pressure transducer is preferably used for the pressure sensor 11.

シリンダーのロッド７の変位による破損検知に、さらに、圧力センサ１１による破損を検知することは、湾曲した板ガラスの枠体成形中の破損を確実に検知することが可能となるので好ましい。   In addition to detecting breakage due to displacement of the rod 7 of the cylinder, it is preferable to detect breakage by the pressure sensor 11 because it is possible to reliably detect breakage during the frame forming of the curved plate glass.
