Description

【0001】
【発明の属する技術分野】
本発明は、板状部材に樹脂部材を一体成形する板状部材への射出成形方法およびその装置に関するものである。
【0002】
【従来の技術】
図13〜図18は従来の板状部材への射出成形方法およびその装置の第一例を示す概略図である。
【0003】
この板状部材への射出成形装置の第一例は、板状部材のウインドガラス1に樹脂原料を射出して樹脂部材2を一体成形する成形機3と、ウインドガラス1を成形機3へ搬入および搬出する搬送手段の型外機4とを備えている。成形機3は、ウインドガラス1を挟み込んでキャビティ(図示せず)を形成するよう第一の成形型5と第二の成形型6を配するとともに射出機(図示せず)を付設している。搬送手段の型外機4は、ウインドガラス1を吸着手段7aを介して下側で保持し得る保持部7を配するとともに保持部7を支持する腕部8を備えている。
【0004】
ウインドガラス1の周囲にモールディングなどの樹脂部材2を備える際には、ウインドガラス1を成形機3に搬入する搬入工程と、ウインドガラス1に樹脂部材2を一体成形する射出工程と、ウインドガラス1を成形機3から搬出する搬出工程とを行う。
【0005】
搬入工程は、ウインドガラス1を型外機4の保持部7に吸着手段7aを介して保持し、型外機4によりウインドガラス1を成形機3に搬送して吸着手段7aの解除により第一の成形型5の挟込位置に載置する。つぎに射出工程は、第二の成形型6を第一の成形型5に降ろして型締めし、射出機によりキャビティに樹脂原料を射出してウインドガラス1にモールディングなどの樹脂部材2を一体成形する。続いて搬出工程は、図13〜図15に示すごとく、第二の成形型6を昇降させて成形機3を開き、射出処理後のウインドガラス1を型外機4の保持部7に吸着手段7aを介して保持し、型外機4により射出処理後のウインドガラス1を第一の成形型5から成形機3外へ搬出する。さらに射出処理後のウインドガラス1を搬出した後には、図16〜図18に示すごとく、新たなウインドガラス1を型外機4の保持部7に吸着手段7aを介して保持し、ふたたび搬入工程を行う。
【0006】
このようにウインドガラス1の周囲にモールディングなどの樹脂を備える際には、搬入工程から射出工程を介して搬出工程に移行する工程を繰り返し、ウインドガラス1への射出成形を連続的に行う。
【0007】
図19〜図24は従来の板状部材への射出成形方法およびその装置の第二例を示す概略図である。また、図19〜図24において図13〜図18の従来の第一例と同一の符号を付した部分は同一物を表わしている。
【0008】
この板状部材の射出成形装置の第二例は、板状部材のウインドガラス1に樹脂原料を射出して樹脂部材2を一体成形する成形機3と、ウインドガラス1を成形機3へ搬入および搬出する搬送手段のロボットアーム9とを備えている。成形機3は、第一例とほぼ同様に、ウインドガラス1を挟み込んでキャビティ(図示せず)を形成するよう第一の成形型5と第一の成形型6を配するとともに射出機(図示せず)を付設している。搬送手段のロボットアーム9は、ウインドガラス1を吸着手段10aを介して保持し得る保持部10を配するとともに複数の関節部11を有する腕部12を備えている。
【0009】
ウインドガラス1の周囲にモールディングなどの樹脂部材2を備える際には、第一例とほぼ同様に、ウインドガラス1を成形機3に搬入する搬入工程と、ウインドガラス1に樹脂部材2を一体成形する射出工程と、ウインドガラス1を成形機3から搬出する搬出工程とを行う。
【0010】
搬入工程は、ウインドガラス1をロボットアーム9の保持部10に吸着手段10aを介して保持し、ロボットアーム9によりウインドガラス1を成形機3に搬送して吸着手段10aの解除により第一の成形型5の挟込位置に載置する。つぎに射出工程は、図19に示すごとく、第二の成形型6を第一の成形型5に降ろして型締めし、射出機によりキャビティに樹脂原料を射出してウインドガラス1にモールディングなどの樹脂部材2を一体成形する。続いて搬出工程は、図20〜図22に示すごとく、第二の成形型6を昇降させて成形機3を開き、射出処理後のウインドガラス1をロボットアーム9の保持部10に吸着手段10aを介して保持し、ロボットアーム9により射出処理後のウインドガラス1を第一の成形型5から成形機3外へ搬出する。さらに射出処理後のウインドガラス1を搬出した後には、図23、図24に示すごとく、新たなウインドガラス1を型外機4の保持部10に吸着手段10aを介して保持し、ふたたび搬入工程を行う。
【0011】
このように第二例においてウインドガラス1の周囲にモールディングなどの樹脂を備える際には、第一例とほぼ同様に、搬入工程から射出工程を介して搬出工程に移行する工程を繰り返し、ウインドガラス1への射出成形を連続的に行う。
【0012】
しかしながら、従来例のように射出処理後のウインドガラス1を搬送手段により成形機3から搬出した後に、新たなウインドガラス1を同じ搬送手段により成形機3に搬入すると、射出機の非稼働時間が長く、ウインドガラス1の一枚当たりの樹脂部材成形時間が長くなるため、生産効率が悪いという問題があった。
【0013】
そこで、生産効率を改善するために、新たなウインドガラスを載置する第一の成形型を左右両側に用意し、一方の第一の成形型と第二の成形型とを型締めして、ウインドガラスに樹脂原料を射出して樹脂部材を一体成形している間に、もう一方の第一の成形型では、射出処理後のウインドガラスの搬出作業と、新たなウインドガラスの載置作業とを行い、第二の成形型が開いた際に射出処理後のウインドガラスを載置した第一の成形型が成形機外へ移動し、新たなウインドガラスを載置した第一の成形型が成形機内へ移動するというような成形機へ2つの第一の成形型を交互に移送する板状部材への射出成形方法およびその装置がある(例えば、特許文献1、2参照)。

【発明が解決しようとする課題】
ウインドガラスは、型式毎に様々な形状をし、型式が変われば成形型も新たに製作しなければならなく、非常にコストのかかるものである。したがって、特許文献1、2の発明のように第一の成形型を2つも製作しているとコストがさらにかかってしまい現実的でない。
【0016】
本発明はこのような実情に鑑みてなしたもので、設備に対してコストをかけずに射出機の非稼働時間を短くしてウインドガラスの一枚あたりの樹脂部材成形時間を短くし、生産効率を向上させる板状部材への射出成形方法およびその装置を提供することを目的とするものである。
【0017】
【課題を解決するための手段】
上記目的を達成するため請求項1に記載の本発明は、板状部材を搬送手段により成形機内に搬送して第一の成形型の所定位置にセットする搬入工程と、前記第一の成形型を第二の成形型で閉じて型締めし、前記第一の成形型と第二の成形型とで形成されたキャビティに樹脂原料を射出して板状部材に樹脂部材を一体成形する射出工程と、前記第二の成形型を開き、射出処理後の板状部材を搬送手段により成形機外へ搬送する搬出工程とを繰り返す板状部材への射出成形方法において、
射出工程の後に第二の成形型を開いた際に、前記射出処理後の板状部材を第二の成形型に保持し、新たな板状部材を搬送手段により成形機内に搬送して第一の成形型の所定位置にセットし、前記射出処理後の板状部材を前記搬送手段により第二の成形型から成形機外へ搬送し、前記搬送手段の成形機への一往復により搬入工程と搬出工程とを行うことを特徴とする板状部材への射出成形方方法、に係るものである。
【0018】
請求項2に記載の本発明は、第一の成形型に板状部材を配置し、前記第一の成形型と第二の成形型とを型締めした際に形成されるキャビティに樹脂原料を射出して板状部材に樹脂部材を一体成形する成形機と、新たな板状部材を成形機内へ搬入しかつ射出処理後の板状部材を成形機外へ搬出する搬送手段とを備えた板状部材への射出成形装置において、
前記成形機は、第二の成形型を開いた際に、前記射出処理後の板状部材を第二の成形型の所定位置に配置し得る支持手段を備えていることを特徴とする板状部材への射出成形装置、に係るものである。
【0019】
請求項3に記載の本発明は、前記搬送手段は、板状部材を二枚保持し得る保持部を備えている請求項2に記載の板状部材への射出成形装置、に係るものである。
【0020】
このように本発明によれば、搬送手段の成形機への一往復により、新たな板状部材の搬入工程、および射出成形後の板状部材の搬出工程を行うので、設備に対してコストをかけずに射出機の非稼働時間を短くしてウインドガラスの一枚当たりの樹脂部材成形時間を短くし、生産効率を向上させることができる。
【0021】
【発明の実施の形態】
以下、本発明の実施の形態を図示例とともに第一例を説明する。図1〜図5は、本発明の実施の形態の第一例において板状部材のウインドガラス1に樹脂原料を射出して樹脂部材を一体成形する手順を示す概略図であり、図6、図7は、板状部材を支持する支持手段の概略図である。
【0022】
本発明の板状部材への射出成形装置の第一例は、板状部材のウインドガラス1に樹脂原料を射出して樹脂部材2を一体成形する成形機13と、ウインドガラス1を成形機13へ搬入および搬出する搬送手段の型外機14とを備えている。
【0023】
成形機13は、ウインドガラス1を挟み込んでキャビティ(図示せず)を形成するよう第一の成形型15と第二の成形型16を配するとともに射出機(図示せず)を付設している。また、第二の成形型16のウインドガラス対抗面17には、ウインドガラス1を懸吊する支持手段18を備えている。ここで、一例の支持手段18は、図6に示すごとく、エアーシリンダ19と、シリンダロッド20の先端に配置された真空吸着部21と、真空吸着部21に接続されたエアーライン22とを備えて構成されている。また、他の例の支持手段18’として、図7に示すごとく、ケース23に収納されたスプリングなどの弾性体24と、ケース23外の弾性体24の先端に延在部25を介して配置された真空吸着部26と、真空吸着部26に接続されたエアーライン27とを備えたものがある。
【0024】
搬送手段の型外機14は、ウインドガラス1を保持し得る保持部28を配するとともに保持部28を支持する腕部29を備えている。保持部28は、下面および上面にそれぞれウインドガラス1を一枚ずつ計二枚を保持し得る真空吸着などの吸着手段30を備えている。
【0025】
以下、第一例の板状部材への射出成形方法およびその装置の作用を説明する。
【0026】
ウインドガラス1の周囲にモールディングなどの樹脂部材2を備える際には、ウインドガラス1を成形機13に搬入する搬入工程と、ウインドガラス1に樹脂部材2を一体成形する射出工程と、ウインドガラス1を成形機13から搬出する搬出工程とを行う。生産開始等の一枚目の搬入工程はウインドガラス1を型外機14の保持部28の下面に吸着手段30を介して保持し、型外機14によりウインドガラス1を成形機13に搬送して吸着手段30の解除により第一の成形型15の挟込位置に載置する。つぎに、射出工程は、第二の成形型16を第一の成形型15に降ろして型締めし、射出機によりキャビティに樹脂原料を射出してウインドガラス1にモールディングなどの樹脂部材2を一体成形している。
【0027】
つぎに、射出処理後のウインドガラス1を成形機13から搬出する搬出工程は、図1に示すごとく、第二の成形型16を昇降させて成形機13を開き、射出処理後のウインドガラス1を第二の成形型16の支持手段18に懸吊する。ここで、支持手段18は、射出工程において第一の成形型15と第二の成形型16を閉じた際に、エアーシリンダ19または弾性体24により、射出成形の障害とならないよう真空吸着部21、26を上方に収納可能に構成されている。
【0028】
続いて、新たなウインドガラス1を、図2に示すごとく、型外機14の吸着手段30を介し保持部28の下面に保持して型外機14により成形機13内に搬送し、吸着手段30の解除により型外機14の保持部28から離して第一の成形型15の挟込位置に配置する。さらに、図3に示すごとく、型外機14の保持部28を昇降させて、射出処理後のウインドガラス1を、型外機14の吸着手段30を介し保持部28の上面に保持する。つぎに、図4、図5に示すごとく、型外機14により射出処理後のウインドガラス1を第二の成形型16から成形機13外へ搬送する。ここで、射出処理後のウインドガラス1を型外機14の保持部28の上面に保持した際には、型外機14の吸着手段30の保持作動に連動して、第二の成形型16の支持手段18が射出処理後のウインドガラス1の保持を解除している。なお、支持手段18、18’のエアーシリンダ19、真空吸着部21、26は搬送工程、射出工程、搬出工程などに合わせて適宜作動するよう、成形機13の外部から制御されている。
【0029】
続いて、型外機14の成形機13への一往復により搬入工程と搬出工程とを行った後には、第二の成形型16を閉じて型締めし、新たなウインドガラス1に原料樹脂を射出してモールディングなどの樹脂部材2を一体成形する射出工程を行う。以後、新たなウインドガラス1の搬入工程および射出処理後のウインドガラス1の搬出工程、射出工程を繰り返し、ウインドガラス1への射出成形を連続的に行う。
【0030】
このように第一例の板状部材への射出成形方法およびその装置によれば、型外機14の成形機13への一往復により、新たなウインドガラス1の搬入工程、および射出成形後のウインドガラス1の搬出工程を行うので、射出機の非稼働時間を短くしてウインドガラス1の一枚当たりの樹脂部材成形時間を短くし、生産効率を向上させることができる。
【0031】
請求項2に記載のごとく、成形機13は、第二の成形型16を開いた際に、前記射出処理後のウインドガラス1を第二の成形型16の所定位置に配置し得る支持手段18、18’を備えていると、射出工程の後に第二の成形型16を開いた際に、射出処理後のウインドガラス1と第二の成形型16が干渉することがなく、射出処理後のウインドガラス1を安全に取り出すことができる。
【0032】
請求項3に記載のごとく、搬送手段の型外機14は、ウインドガラス1を二枚保持し得る保持部28を備えていると、新たなウインドガラス1の搬入工程、および射出成形後のウインドガラス1の搬出工程を迅速に行うので、射出機の非稼働時間を一層短くして生産効率をさらに向上させることができる。
【0033】
以下、本発明の実施の形態の第二例を説明する。図8〜図12は、本発明の実施の形態の第二例において板状部材のウインドガラス1に樹脂原料を射出して樹脂部材2を一体成形する手順を示す概略図である。また、図8〜図12において図1〜図7の第一例と同一の符号を付した部分は同一物を表わしている。
【0034】
本発明の板状部材への射出成形装置の第二例は、板状部材のウインドガラス1に樹脂原料を射出して樹脂部材2を一体成形するよう第一例とほぼ同様な構成からなる成形機13と、ウインドガラス1を成形機13へ搬入および搬出する搬送手段のロボットアーム31とを備えている。ここで、搬送手段のロボットアーム31は、一枚のウインドガラス1を吸着手段32を介して保持し得る保持部33を配するとともに複数の関節部34(図では2個)を設けた腕部35を備えている。
【0035】
以下、第二例の板状部材への射出成形方法およびその装置の作用を説明する。
【0036】
ウインドガラス1の周囲にモールディングなどの樹脂部材2を備える際には、第一例とほぼ同様に、ウインドガラス1を成形機13に搬入する搬入工程と、ウインドガラス1に樹脂部材2を一体成形する射出工程と、ウインドガラス1を成形機13から搬出する搬出工程とを行う。生産開始の一枚目の搬入工程はウインドガラス1をロボットアーム31の保持部33の下面に吸着手段32を介して保持し、ロボットアーム31によりウインドガラス1を成形機13に搬送して吸着手段32の解除により第一の成形型15の挟込位置に載置する。つぎに、射出工程は、第二の成形型16を第一の成形型15に降ろして型締めし、射出機によりキャビティに樹脂原料を射出してウインドガラス1にモールディングなどの樹脂部材2を一体成形している。
【0037】
つぎに、ウインドガラス1を成形機13から搬出する搬出工程は、図8、図9に示すごとく、第二の成形型16を昇降させて成形機13を開き、射出処理後のウインドガラス1を第二の成形型16の支持手段18に懸吊する。続いて、新たなウインドガラス1を、図10に示すごとく、ロボットアーム31の吸着手段32を介し保持部33に保持してロボットアーム31により成形機13内に搬送し、吸着手段32の解除によりロボットアーム31の保持部33から離して第一の成形型15の挟込位置に配置する。さらに、図11に示すごとく、ロボットアーム31の保持部33の方向を関節部34、腕部35により上方に変更し、射出処理後のウインドガラス1を、ロボットアーム31の吸着手段32を介し保持部33に保持する。
【0038】
つぎに、図12に示すごとく、ロボットアーム31により射出処理後のウインドガラス1を第二の成形型16から成形機13外へ搬送する。ここで、射出処理後のウインドガラス1をロボットアーム31の保持部33に保持した際には、ロボットアーム31の吸着手段32の保持作動に連動して第二の成形型16の支持手段18が射出処理後のウインドガラス1の保持を解除している。なお、支持手段18、18’のエアーシリンダ19、真空吸着部21、26は搬送工程、射出工程、搬出工程などに合わせて適宜作動するよう、成形機13の外部から制御されている。
【0039】
続いて、ロボットアーム31の成形機13への一往復により搬入工程と搬出工程とを行った後には、第二の成形型16を閉じて型締めし、新たなウインドガラス1に原料樹脂を射出してモールディングなどの樹脂部材2を一体成形する射出工程を行う。以後、新たなウインドガラス1の搬入工程および射出処理後のウインドガラス1の搬出工程、射出工程を繰り返し、ウインドガラス1への射出成形を連続的に行う。
【0040】
このように第二例の状部材への射出成形方法およびその装置によれば、第一例とほぼ同様な作用効果を得ることができる。
【0041】
なお、本発明の板状部材への射出成形方法およびその装置は、上述の形態例にのみ限定されるものではなく、成形機の第一の成形型および第二の成形型は上下方向でなく、左右両側に配置されてもよいこと、ウインドガラスに一体成形する樹脂部材は、ウインドガラスを車両などに取り付ける際に使用する位置決めクリップを備えてもよいこと、その他、本発明の要旨を逸脱しない範囲内において種々変更を加え得ることは勿論である。
【0042】
【発明の効果】
以上説明したように、本発明によれば、搬送手段の成形機への一往復により、新たな板状部材の搬入工程、および射出成形後の板状部材の搬出工程を行うので、設備に対してコストをかけずに射出機の非稼働時間を短くしてウインドガラスの一枚当たりの樹脂部材成形時間を短くし、生産効率を向上させることができるという優れた効果を奏し得る。
