Description

【０００１】
【発明の属する技術分野】
本発明は、射出成形された成形品の組立て方法、及びその組立て装置、及びその製造方法に関し、詳しくは、複数の成形品の組立て工程を削減し、組立て時間を短縮し、高機能の取出しロボットを不要にする等、生産性を高め、装置を簡素化しようとする技術に係るものである。
【０００２】
【従来の技術】
従来、射出成形された複数の成形品Ａ，Ｂの部品をそれぞれの金型で成形加工したり、同一の金型内で同時成形をおこない、それぞれの部品をストックしておき、必要に応じて人手で組立て作業をおこなうものである。
【０００３】
【発明が解決しようとする課題】
ところで、従来の射出成形された複数の成形品の部品の生産及び組立て作業においては、図１５に示すように、複数の金型Ｃ′，Ｃ″、及び成形機の確保が必要となり、金型管理費用、製造上のロスが大きく、又、人手による組立てが必要となり、工数がかかり、組立て時間が長くなるものである。ロボットのような組立て設備を別途に製作することにより、組立て時間を削減することができるが、多額の初期投資、及び設備の設置スペースの確保をしなければならない、等という問題があった。
【０００４】
又、図１６に示す特開平８−２２４７５９号のように、高機能のロボットＲａを射出成形機に設置したり、別途、組立て設備を設置することにより、金型から取り出した成形品の組立てをおこなうことが可能となるが、品種の切換えが多い製品の組立ての場合、取出し／組立てロボットの設定を頻繁に変更する必要がある等の問題がある。図中Ｃは金型である。
【０００５】
本発明はこのような問題に鑑みてなされたものであり、複数の成形品の組立て工程を削減し、組立て時間を短縮し、高機能の取出しロボットを不要にする等、生産性を高め、装置を簡素化することができる成形品の組立て方法、及びその組立て装置、及びその製造方法を提供することを課題とするものである。
【０００６】
【課題を解決するための手段】
請求項１においては、組立て可能な複数の成形品Ａ，Ｂを、一つの金型Ｃで同時成形し、取出しロボットＲにて取り出した一方の成形品Ａを他方の成形品Ｂに位置合わせし、成形品Ｂが取り付いている型部Ｃｂを移動させて、成形品Ｂの回転ねじ込みにより、成形品Ａ，Ｂの組立てを金型Ｃの内部でおこなうことを特徴とするものである。このような構成によれば、金型Ｃの内部において組立てがおこなえるのであり、成形品Ａ，Ｂをそれぞれ製造してストックし、必要時に人手で組立て、又、別途に組立てロボットを投入する従来の製作工程に比べて、複数の成形品の組立て工程を削減し、組立て時間を短縮し、高機能の取出しロボットを不要にして、高価な組立て設備を設置することなく複数の成形品Ａ，Ｂの組立てが可能になり、更に、複数の独立した金型が不要になることで、金型管理費用の削減、組立てまでの部品ストック・管理費用の削減がおこなえ、製造計画の柔軟性が増すものである。
【０００７】
更に、請求項１においては、成形品Ｂの回転ねじ込みにより、組立てをおこなうことを特徴とするものである。このような構成によれば、回転ねじ込み設備を外部に設置することなく、金型Ｃの内部で成形品Ａ，Ｂによるねじ部品の組立てをおこなうことができるものである。
【０００８】
請求項２においては、組立て可能な複数の成形品Ａ，Ｂを、一つの金型Ｃで同時成形し、取出しロボットＲにて取り出した一方の成形品Ａを他方の成形品Ｂに位置合わせし、成形品Ｂを成形品Ａに軸心方向に押し込んだ後回転させ、その回転をロック手段にて回転ロックすることにより、組立てを金型Ｃの内部でおこなうことを特徴とするものである。このような構成によれば、成形品Ｂを成形品Ａに軸心方向に押し込んだ後回転させてロックさせる設備を外部に設置することなく、金型Ｃの内部で成形品Ａ，Ｂの組立てをおこなうことができ、しかも、ねじ込み動作のような複雑な動作を必要とせず、装置を簡素化できるものである。
【０００９】
請求項３においては、組立て可能な複数の成形品Ａ，Ｂを同時成形する金型Ｃと、一方の成形品Ａを取出して他方の成形品Ｂに位置合わせする取出しロボットＲと、取出しロボ ットＲによって取り出した成形品Ａを他方の成形品Ｂに位置合わせした後、成形品Ｂが取り付いている型部Ｃｂを回転させるとともに前進させて、双方の成形品Ａ，Ｂを金型Ｃ内でねじ込みにて組立てる手段を備えていることを特徴とするものである。このような構成によれば、回転ねじ込み設備を外部に設置することなく、金型Ｃの内部で成形品Ａ，Ｂによるねじ部品の組立てをおこなうことができるものである。
【００１０】
請求項４においては、ねじ込み運動の回転力のみを一方の成形品Ｂに伝達する回転伝達手段１と、ねじのリード分の軸心方向の移動を吸収する軸心方向移動量吸収手段２を備えていることを特徴とするものである。このような構成によれば、複雑なねじ運動を不要にできて構成を簡素化することができるものである。
【００１１】
請求項５においては、型部Ｃｂに取り付いている成形品Ｂのねじ込み回転動作時に成形品Ｂを保持し、双方の成形品Ａ，Ｂのねじ込み組立て後に型部Ｃｂから成形品Ｂを引き抜くための抜き勾配Ｔを形成していることを特徴とするものである。このような構成によれば、ねじ込み回転動作時に成形品Ｂを保持しながら、ねじ込みによる組立て後に、抜き勾配Ｔによって成形品Ｂを型部Ｃｂから楽に抜くことができ、例えば、取出しロボットＲのハンドで抜くことができるものである。
【００１２】
請求項６においては、成形品Ａと成形品Ｂのねじ込み組立て後に成形品Ｂを保持している型部Ｃｂの温度を変化させ、成形品Ｂの引き抜き力を調整する手段を備えていることを特徴とするものである。このような構成によれば、型部Ｃｂの形状を抜き易いように考慮することなく、型部Ｃｂの温度を調整することで、成形品Ｂを楽に抜くことができるものである。
【００１３】
請求項７においては、射出成形機の型閉じ動作を成形品Ｂを取り付けている型部Ｃｂの回転運動に変換する機構３を備えていることを特徴とするものである。このような構成によれば、射出成形機の型閉じ力を型部Ｃｂの回転運動に変換することができ、射出成形機以外の動力源を使用することなく、金型Ｃの内部で成形品Ａ，Ｂの組立てをおこなうことができるものである。
【００１４】
請求項８においては、成形品Ａと成形品Ｂのねじ込み開始時の安定性を確保するために型部Ｃｂに取り付いている成形品Ｂに付勢力を与える機構４を備えていることを特徴とするものである。このような構成によれば、成形品Ｂに付勢力を与えることで、ねじ込み開始を安定させてねじ込みを安定的におこなうことができるものである。
【００１５】
請求項９においては、組立て可能な複数の成形品Ａ，Ｂを、一つの金型Ｃで同時成形し、取出しロボットＲにて取り出した一方の成形品Ａを他方の成形品Ｂに位置合わせし、成形品Ｂが取り付いている型部Ｃｂをねじ込み移動させて、成形品Ａ，Ｂの組立てを金型Ｃの内部でおこなわれて製造される成形品の製造方法であって、成形品Ａ，Ｂの雄ねじ及び雌ねじ部分にはクリアランスＱを取っていることを特徴とするものである。このような構成によれば、金型Ｃの内部においてねじ込みによって成形品Ａ、Ｂの組立てがおこなえるのであり、成形品Ａ，Ｂをそれぞれ製造してストックし、必要時に人手で組立て、又、別途に組立てロボットを投入する従来の製作工程に比べて、複数の成形品の組立て工程を削減し、組立て時間を短縮し、高機能の取出しロボットを不要にして、高価な組立て設備を設置することなく複数の成形品Ａ，Ｂの組立てが可能になり、更に、複数の独立した金型が不要になることで、金型管理費用の削減、組立てまでの部品ストック・管理費用の削減がおこなえ、製造計画の柔軟性が増す等という利点があり、特に、クリアランスＱによって、成形品Ａ，Ｂのねじ込み嵌合時の回転抵抗が過大となることを防止でき、ねじ込みによる組立てを円滑におこなうことができるものである。
【００１６】
請求項１０においては、組立て可能な複数の成形品Ａ，Ｂを、一つの金型Ｃで同時成形し、取出しロボットＲにて取り出した一方の成形品Ａを他方の成形品Ｂに位置合わせし、成形品Ｂが取り付いている型部Ｃｂを軸心方向に移動させた後、回転させその回転をロックして、成形品Ａ，Ｂの組立てを金型Ｃの内部でおこなわれることを特徴とするものである。このような構成によれば、金型Ｃの内部において成形品Ａ、Ｂの組立てがおこなうことができるのであり、成形品Ａ，Ｂをそれぞれ製造してストックし、必要時に人手で組立て、又、別途に組立てロボットを投入する従来の製作工程に比べて、複数の成形品の組立て工程を削減し、組立て時間を短縮し、高機能の取出しロボットを不要にして、高価な組立て設備を設置することなく複数の成形品Ａ，Ｂの組立てが可能になり、更に、複数の独立した金型が不要になることで、金型管理費用の削減、組立てまでの部品ストック・管理費用の削減がおこなえ、製造計画の柔軟性が増すのであり、特に、成形品Ｂが取り付いている型部Ｃｂを軸心方向に移動させた後、回転させその回転をロックすることで、組立てられた成形品Ａ、Ｂの分解を強力に阻止することができ、組立て力を高めることができるものである。
