Description

【0001】
【発明が属する技術分野】
本発明は、チャックを旋回させて樹脂成形機から成形品を取出す旋回形成形品取出機に関する。
【0002】
【従来技術】
従来、特許文献1に示す旋回形成形品取出機が知られている。この旋回形成形品取出機は、1個の電動モータによりスイングアームを旋回運動させて該アームの先端部に設けられたチャックを金型内に進入させた後にスイングアームを直線運動して可動金型内に保持された成形品に近接した状態で相対させて成形品を保持して取出している。
【0003】
【特許文献1】
特開2001−349405号
【0004】
【発明が解決しようとする課題】
しかし、上記した旋回形成形品取出機は、スイングアームを旋回運動させた後に直線運動させる構造のため、金型内から成形品を取出すのに時間がかかっている。特に、この種の旋回形成形品取出機は、例えばCD、DVD等のディスク状成形品を取出すのに使用されるもので、1/10〜1/100秒台の極めて短時間に成形品を取出す必要がある。
【0005】
また、上記した旋回形成形品取出機にあっては、電動モータの回転運動を、スイングアームの回転運動及び直線運動という2つの運動に変換する機構として、規制用カム溝及び駆動用カム溝の2つのカム溝を設けたカム部材と、夫々のカム溝を摺接するカムフォロアーとから構成されるカム機構を採用している。
【0006】
しかし、このカム機構を採用した場合にあっては、旋回運動を停止させる際や直線運動を停止させる際に、カム溝の端部にカムフォロアーを押し当てて移動規制する構造であるため、スイングアームの移動停止時における衝撃が大きくなっている。
【0007】
このため、移動停止時における衝撃によりカム機構が短時間に損傷し易く、取出機自体の耐久性が悪くなる問題を有していると共にスイングアーム停止時に発生する衝撃によりチャックから保持された成形品が脱落し易くなって取出し不良発生の要因となっていた。
【0008】
本発明は、上記した従来の欠点を解決するために発明されたもので、その課題とする処は、旋回アームの旋回運動及び直線運動を同時に行うことにより成形品取出し時間を大幅に短縮して高速取出しを可能にする旋回形成形品取出機を提供することにある。
【0009】
本発明の他の課題は、取出機自体の耐久性を高めることができると共に旋回アームの回動停止における衝撃を低減して取出し不良を防止することができる旋回形成形品取出機を提供することにある。
【0010】
【課題を解決するための手段】
請求項1の旋回形成形品取出機は、樹脂成形機の固定プラテンに固定される本体フレームに少なくとも一端部が回転可能に支持され、樹脂成形機の軸線と一致する方向に軸線を有した送りねじと、該送りねじに回転可能に軸支されたナット部材と、該ナット部材に基端部が固定されると共に先端部に成形品を保持するチャック部材が設けられる旋回アームと、本体フレームに軸線方向へ移動可能に支持されると共にナット部材及び旋回アームの基端部の少なくとも一方に連結される電動モータとを備え、該電動モータの回転駆動に伴って旋回アームを回動させると共に軸線方向へ移動するように構成したことを特徴とする。
【0011】
請求項3の旋回形成形品取出機は、樹脂成形機の固定プラテンに固定される本体フレームに少なくとも一端部が回転可能に支持され、樹脂成形機の軸線と一致する方向に軸線を有した送りねじと、該送りねじに回転可能に軸支されたナット部材と、該ナット部材に基端部が固定されると共に先端部に成形品を保持するチャック部材が設けられる旋回アームと、ナット部材及び旋回アームの基端部の少なくとも一方に固定され、外周に係合溝が形成されたスプライン軸部材と、本体フレームに軸線方向に軸線を有して固定される電動モータと、スプライン軸部材の係合溝に噛合い、軸線方向へ移動可能なスプライン外筒部材とを備え、電動モータの回転駆動に伴って旋回アームを回動させると共に軸線方向へ移動するように構成したことを特徴とする。
【0012】
【発明の実施形態】
以下に実施形態を示す図に従って本発明を説明する。
実施形態1
図1〜図3において、旋回形成形品取出機1の固定ベース3は樹脂成形機の固定プラテン5の上面に固定される。該固定ベース3は固定プラテン5の上面から起立した後に樹脂成形機の可動プラテン(図示せず)側に向って延出する平面部3aと、該平面部3aの先端部にて垂下する固定部3bを有した形状に形成される。尚、上記固定ベース3は固定プラテン5の上面に対し、長孔を介してボルト止めすることにより軸線直交方向へ位置調整可能に固定される。
【0013】
固定ベース3の固定側下面には軸線方向へ延出するレール7が固定され、該レール7には可動台9が軸線方向へ移動可能に支持される。そして該可動台9には軸線方向に軸線を有したサーボモータ等の電動モータ11が固定される。
【0014】
該電動モータ11の回転軸11aには円筒形状のカップリング部材13が減速機構15を介して連結される。該カップリング部材13の出力側には軸線方向の深さが後述する旋回アーム25の直線移動ストローク以上からなる中空部13aが同心円状に形成される。そして中空部13a内には軸受21が軸線方向へ摺動するように設けられ、固定ベース3の固定部3bと中空部13aの軸受21には樹脂成形機の軸線方向に軸線を有した送りねじ17が固定される。即ち、固定ベース3の固定部3bには送りねじ17の一方端部が固定されると共に送りねじ17の他方端部は中空部13a内の軸受21に固定されて回転不能に取付けられる。
【0015】
上記した送りねじ17にはボールナットやニードルナット等のナット部材23が回転可能に軸支され、該ナット部材23の小径軸部23aには旋回アーム25の基端部が挿嵌される。そして旋回アーム25が取付けられたナット部材23にはそれぞれの貫通孔23b・25aを挿通する固定ねじ27によりカップリング部材13が固定される。
【0016】
旋回アーム25は、例えばアルミニウム材や炭素繊維等を含有した複合強化樹脂で、先端部側が屈曲したく字形に形成される。そして旋回アーム25の先端部には成形品を吸着して保持する吸着部材や把持するエアーシリンダ等の保持部材29aを備えたチャック29が取付けられる。
【0017】
次に、上記のように構成された旋回形成形品取出機1における旋回アーム25の旋回及び直線移動作用を説明する。
先ず、成形品の取出し動作の概略を説明すると、樹脂成形機から型開信号が出力されると、電動モータ11を駆動制御して旋回アーム25を旋回移動させると共に直線移動してチャック29を型開した金型間に侵入させながら可動金型側へ移動して可動金型内に保持された成形品に近接した状態で相対させる。
【0018】
次に、可動金型内にエゼクタ機構を駆動して可動金型内の成形品をチャック29に向って突き出してチャック29に保持させると共にこのタイミングで電動モータ11を逆転駆動制御して旋回アーム25を上記と反対方向へ旋回移動させながら反対方向へ直線移動して成形品を保持したチャック29を樹脂成形機外の成形品解放位置へ移動させた後、チャック29による成形品の保持を解除して取出し動作を終了する。
【0019】
電動モータ11を駆動制御して旋回アーム25を旋回移動及び直線移動させる際の作用を説明すると、電動モータ11を回転駆動すると、カップリング部材13を介して連結された旋回アーム25を所定の方向へ旋回移動させる。このとき、カップリング部材13には旋回アーム25と共にナット部材23が固定されているため、旋回アーム25の旋回移動と同時に固定された送りねじ17に対してナット部材23も回転させて送りねじ17のリード及びナット部材23の回転量に応じたストロークで直線移動させる。
【0020】
これにより旋回アーム25は電動モータ11の駆動に伴って同時に旋回移動及び直線移動してチャック29を、可動金型内の成形品に近接した状態で相対させると共に金型間から抜き出させて成形品取出し動作を実行する。(図4参照)
【0021】
本実施形態は、1個の電動モータ11により旋回アーム25を同時に旋回移動及び直線移動させることができ、従来の旋回形成形品取出機に比べて旋回アーム25の移動に要する時間を短縮して取出し時間を短縮することができる。
【0022】
また、回転運動を往復運動に変換するための部材を必要とせず、機構を簡素化して耐久性を高くすることができると共に移動停止時における衝撃を少なくし、衝撃によりチャック29から成形品が外れるのを防止して取出し不良の発生を低減することができる。
【0023】
実施形態2
図5及び図6において、旋回アーム25が挿嵌されたナット部材23にはスプライン軸部材51が、貫通孔23b・25aを挿通する固定ねじ53により固定されている。該スプライン軸部材51は少なくとも旋回アーム25の直線移動ストロークに応じた軸線長さで、中心部に旋回アーム25の直線移動ストロークに応じた深さの中空部51aが送りねじ17と同軸状に形成されると共に外周面に軸線方向へ延出する複数条の係合溝51bが形成される。
【0024】
そしてスプライン軸部材51の中空部51a内には軸受55が軸線方向へ移動可能に支持され、該軸受55には一端部が固定部3bに固定された送りねじ17の他端部が固定される。また、固定ベース3に固定された電動モータ11が連結された減速機構15の出力軸にはスプライン外筒部材57が固定され、該スプライン外筒部材57にはスプライン軸部材51が軸線方向へ摺動可能で、回り止めされた状態で挿嵌される。具体的には、スプライン軸部材51及びスプライン外筒部材57はボールスプライン構造からなり、スプライン外筒部材57に内蔵されて転動するボールを係合溝51bに係合し、スプライン軸部材51を回転可能にさせると共に軸線方向への移動を可能にする。
【0025】
尚、他の構成に付いては、実施形態1と同様であるため、図5及び図6に同一の符号を付して詳細な説明を省略する。
【0026】
実施形態2による旋回アーム25の旋回及び直線移動作用を説明すると、図7に示すように電動モータ11を回転駆動すると、スプライン外筒部材57に係合されたスプライン軸部材51を所定の方向へ回転することにより、該スプライン軸部材51に固定された旋回アーム25を旋回動させると同時に送りねじ17に対してナット部材23回転して送りねじ17のリード及びナット部材23の回転量に応じたストロークで軸線方向へ直線移動させる。
【0027】
このとき、送りねじ17の他方端部が固定された軸受55は、中空部51a内にて軸線方向へ移動可能に支持されているため、送りねじ17の固定状態を保ちながら軸線方向に対するスプライン軸部材51の移動を許容して旋回アーム25の直線移動を可能にする。
【0028】
【発明の効果】
本発明は、旋回アームの旋回運動及び直線運動を同時に行って成形品取出し時間を大幅に短縮することができる。装置自体の耐久性を高めることができると共に旋回アームの回動停止における衝撃を低減して取出し不良を防止することができる。
