Description

【0001】
【発明の属する技術分野】
本発明は向き選別供給方法と装置に関し、詳しくは、軸線方向に非対称な供給対象物を軸線方向での各端部の向きが揃うように選別して供給する向き選別供給方法と装置に関するものである。
【0002】
【従来の技術】
軸線方向に非対称な供給対象物としての代表例にキャップ類がある。キャップ類を容器に自動的に装着するのに、キャップの開口側と閉じ側とが軸線方向で同じ向きになる状態で供給している。
【0003】
しかし、金属や合成樹脂などからなる薄肉のキャップ類は外周面がストレートな円筒面をしていることが多い。しかし、一端側が開口し他端側が閉じている関係上実質的には軸線方向に非対称である。このようなキャップ類の開口側と閉じ側とが軸線方向で同じ向きとなるように揃えるのは困難である。そこで従来、選別性能のよい振動フィーダを用いて整列供給するのが一般的になっている。
【0004】
一方、実開平05−44912号公報▲1▼は肩だれを有したヒートスプレッダのような軸線方向の一端側が開放し、他端側が閉じた軸線方向に非対称な部品の向き選別供給装置を開示している。このものは傾斜した滑落面に高さの低い帯状の係止凸部を設け、振動を与えながら部品を落下させる。部品の滑落途上、肩だれ部を下向きとした部品は係止凸部を肩だれ部にて乗り越えながら最下部まで滑落する。平坦面を下向きとした部品は係止凸部を乗り越えることができず、係止凸部の長さ方向に設定した傾斜に沿って側溝に導かれ排出される。
【0005】
また、特開平10−7241号公報▲2▼は軸状のワークをブリッジの生成を防ぎながら軸方向に整列させて搬送する装置を開示している。このものは、ホッパに面して斜め上方に巡回するコンベアに、軸状のワークを係止して搬送するための爪部を設けたものを前後2段に配し、前段の爪の幅および配列ピッチよりも後段の爪の幅および配列ピッチを小さく設定している。前段のコンベアでは前段のホッパ内の軸状のワークを各爪によって粗く掻き上げながら掬い取って係止し、各爪に複数のものが互いに重なってではあるが爪の長手方向にワークの軸線方向がほぼ向く係止状態で搬送し、後段ホッパ内へ適量ずつ順次に投入する。後段のコンベアは軸線方向が揃った状態で後段のホッパに適量ずつ順次に投入されてくるワークを、小さな幅の爪に互いの重なりが生じない少量ずつであるが、前段のコンベアよりは多数の爪で掬い上げ係止していくことにより、前段のコンベアからの供給量とほぼ同じ量を搬送し供給できるようにしている。
【0006】
また、特開2000−15185号公報▲3▼は、ランダムに送り出される筒状の部品を整列させる部品判別整列方法と装置を開示している。このものは、所定の幅を持った傾斜面で部品をほぼ一列ずつ押し上げて前方へ滑落させる押し上げ板をホッパ側から搬送路手段まで多段に設けて、搬送路手段上に一列ずつ部品を間欠に送りつけ、搬送路手段では順次一列ずつ送りつけられる部品を列方向に搬送して画像認識による良否判定と、不良品排除とに供した後、排除されなかった良品、つまり、部品の種類や向きが揃ったもののみ送り出せるようにしている。
【0007】
【発明が解決しようとする課題】
しかし、上記の振動フィーダは高価なうえ、単位時間当たりの供給量が少なく、PETボトルのキャップ類で100個/分程度である。このため、近時の充填機の高速化に対応できず、1つの充填ラインにつき複数台の振動フィーダが必要で設備コストがかさむし、占有スペースが大きい。しかも、PETボトルのキャップのように切り離し用のいわゆるミシン目のあるキャップでは振動の影響で前記ミシン目が不用意に切れ不良品化する問題がある。
【0008】
公報▲1▼に記載の技術では、極く偏平なキャップに対応できるにしても、軸線方向の寸法が大きくなるほど、つまりキャップの高さが高くなるほど、良品でも前方へ転倒しやすくなり選別の効率が勢い低下する。また、向き選別による供給量を増大するために係止凸部を多段に設けると、各係止凸部により良品を受止め排出する位置がそれぞれ異なるので、折角選別されて排出される良品を、選別された向きが乱れないように集合させて次へ供給する手段が必要になる。しかも、振動の影響でキャップのミシン目が切れる問題が生じる。
【0009】
公報▲2▼に記載の技術では、軸状のワークが爪の長手方向に揃うにしても、軸線方向に非対称なものにつき、軸線方向に一端側と他端側とが同じ向きとなるような選別はできない。公報▲2▼に記載の技術は軸方向に非対称なワークの一端側と他端側との向きを揃えるのに、ワークの一端側寄りに大径部があるのを利用して、後段の選別装置にてワークの大径部を溝の開口縁で受け止め、この大径部から長い側の軸部を溝内に落ち込ませるようにしている。従って、選別機構が2種類必要であり構造が複雑で高価につくし、占有スペースが大きい。
【0010】
公報▲3▼に記載の技術では、ホッパ内のランダムな部品を一列に整列させる機構と、一列に整列された部品をその列方向に搬送する搬送路手段と、搬送路手段によって列方向に搬送される部品の向きなどを画像認識する手段と、画像認識の結果に基づき不良品を排除する機構と、排除された不良品をホッパ内に戻す機構とが必要で装置が複雑かつ高価なものとなるし、占有スペースが大きい。しかも、最終に一列に並んだ部品の中で良品であることの割合が低く単位時間あたりの供給量が十分得られない問題がある。
【0011】
本発明の目的は、軸線方向に非対称な供給対象物の軸線方向での向きを選別して供給するのに、簡単かつ安価に不良品化なく単位時間当たり十分な供給量にて供給することが小さなスペースでできる向き選別供給方法と装置を供することにある。
【0012】
【課題を解決するための手段】
上記のような目的を達成するために、本発明の向き選別供給方法は、複数の供給対象物を受載できるように横方向に延び、特定の側に向く特定物以外の向きの非特定物は自重により落下する選別形態を持ったホルダが、供給対象物を溜め置くホッパ内でまたはホッパ内に面して順次に上動する経路を持つように、前記ホルダを巡回させることにより、ホルダがホッパ内の供給対象物を掬い上げて前記特定物のみを受載して、所定の送り出し位置まで持上げることを繰り返し、送り出し位置ではエアの吹き付けによりホルダ上の特定物をホルダの一端側に送り出し向きを揃えて供給するのに併せ、所定の位置より下のホルダ上の特定物はエアの吹き付けにより一端側に詰める前詰めを行っておくことを主たる特徴としている。
【0013】
これを達成する装置は、上向きの受載部が複数の供給対象物を受載できるように横方向に延び、特定の側に向く特定物以外の向きの非特定物を自重により落下させるホルダと、供給対象物を溜め置くホッパと、前記ホルダを前記ホッパ内でまたはホッパ内に面して順次に上動する経路を持つように巡回させる巡回駆動機構とを備えた向き選別供給装置において
ホルダが上動する経路での所定の送り出し位置とその下の位置とでホルダ上の特定物をエアの吹き付けにより一端側に送り出すエアブロー手段と、所定の位置ではホルダの一端側を開放して送られてくる特定物の送り出しを邪魔せず、送り出し位置の下ではホルダの一端側を閉じて送られてくる特定物を受け止め詰めさせる閉じ手段とを設けたことを主たる特徴としている。
【0014】
これら方法および装置の構成では、ホルダが供給対象物を溜め置くホッパ内でまたはホッパ内に面して上動するように巡回されるとき、ホッパ内でまたはホッパ内に面して上動する間、ホッパ内に溜められている供給対象物群と引っ掛かり合ってそれを掻き上げながら掬っていくことを繰り返し、ホルダが供給対象物のうち特定の側に向く特定物を受載し、それ以外の向きの非特定物は自重により落下させることによって、特定物だけを持上げて供給対象物の向きを確率よく選別することをホルダの全長に亘って同時に行なうので、ホルダの長さ、ホッパ内でまたはホッパ内に面してホルダが上動する距離、およびホッパ内でまたはホッパ内に面してホルダが上動する単位時間当たりの回数、のそれぞれに比例して選別効率が向上し、供給対象物中の向きを選別した特定物を必要スペースが小さい簡単な方法および装置にて安価に不良品化なく単位時間当たり十分な供給量にて供給することができる。また、送り出し位置ではホルダ上の特定物はエアを吹き付けてその一端側に送り出し供給するので、特定物をそれと離れた位置から機械的には無接触に送り出せて干渉の問題がない。しかも、送り出し位置の下でもエアの吹き付けによりホルダ上の特定物をホルダの一端の側に送り前もって詰めておく前詰めにより、送り出し位置で特定物相互の間合いを詰める時間が不要になるので供給時間が短縮する。
【0016】
受載部は、前記特定物を下方より受ける受載壁と、この受載壁の背部で特定物の軸方向一端に添わせる背面壁とを有した単純なものとして、軸線方向寸法よりも軸直角方向の寸法が大きなものにつき、前記選別条件を満足することができ、安価に実現する。
【0017】
この場合、さらに、受載壁が背面壁と反対の側で立ち上がるフランジを有し、背面壁との間に上向きの溝を形成している構造では、端部で外へ広がるテーパ状部分の有無など軸線方向端部での形状や大小の違いを、溝での大きな部分の受入れ機能によって吸収して受載姿勢が特に変化しないようにし、選別フランジによる供給対象物の支持点に対する供給対象物の重心上鉛直線の位置が受載部側かどうかによって特定物と非特定物とをより選別しやすくするとともに、特定物については背面壁によるサポートにてより安定に受載できるようにするので、向き選別の確実性と汎用性を高めることができる。
【0019】
巡回駆動機構はホルダを間欠に巡回させることにより、ホルダが停止と上動を繰り返すときの脈動により、ホルダおよび受載部とホッパ内の供給対象物との引っ掛かりを強めて受載状態が安定な特定物の持ち上げ確率を上げながら、受載が不安定な非特定物に対しては上動再開の都度働く慣性によって落下を促進するので、特定物の持上げ効率をさらに高めることができるとともに、特定物の送り出し位置を前記間欠な巡回方式によるホルダの所定の停止位置とすることにより、横長な1つのホルダによって多数の特定物を向き選別して持上げ1箇所にて他に供給することがホルダの停止位置と停止時間とを利用して着実に達成することができる。
【0020】
本発明のそれ以上の特徴は、以下の詳細な説明および図面の記載によって明らかになる。本発明の各特徴は、可能な限りにおいて、それ単独で、あるいは種々な組み合わせで複合して用いることができる。
【0021】
【発明の実施の形態】
以下、図を参照しながら本発明の実施の形態に係る向き選別供給方法およびその装置につき詳細に説明し、本発明の理解に供する。
【0022】
本実施の形態はPETボトルの合成樹脂製キャップを向き選別供給する方法および装置の場合の一例である。しかし、本発明はこれに限られることはなく、軸線方向に非対称な供給対象物一般につき軸線方向での向きを選別して供給する場合に適用して有効であり、これらも本発明の範疇に属する。
【0023】
本実施の形態に係る向き選別供給方法は、図1〜図10に示す向き選別装置を参照して説明すると、上向きの受載部1が横方向に延び、供給対象物であるキャップ2のうち軸線方向Xが受載部1と直角でかつ軸線方向Xに非対称な特定の一端である開口側2aが特定の側に向く図4、図6、図7(a)、図10に示す特定物2Aを重心G上の鉛直線Zが受載部1から外れないようにして受載し、それ以外の向きの図8〜図10に示すような非特定物2Bは重心G上の鉛直線Zが受載部1から外れて自重により落下する選別断面形状および選別姿勢を持ったホルダ3が、キャップ2を溜め置く図1、図4に示すようなホッパ4内でまたはホッパ4内に面して順次に上動する経路を持つように、前記ホルダ3を巡回させることにより、ホルダ3がホッパ4内を上動するときにホッパ4内のキャップ2をホルダ3の受載部1で掬い上げて、前記特定物2Aのみを受載して持上げ、所定の位置まで持上げた特定物2Aをホルダ3の一端3aに送り出し向きを揃えて他に供給する。
【0024】
これを達成するのに装置は、上記のように上向きの受載部1が横方向に延び、キャップ2のうち軸線方向Xが受載部1と直角でかつ軸線方向Xに非対称な特定の一端である開口側2aが特定の側に向く特定物2Aを重心G上の鉛直線Zが受載部1から外れないようにして受載し、それ以外の向きの非特定物2Bは重心G上の鉛直線Zが受載部1から外れて自重により落下する選別断面形状を持ったホルダ3と、キャップ2を溜め置くホッパ4と、前記ホルダ3を前記ホッパ4内でまたはホッパ4内に面して順次に上動する経路を持つように巡回させる図1〜図4に示すような巡回駆動機構5と、ホルダ3により所定の位置まで持上げられた特定物2Aをホルダ3の一端3aから送り出す図4、図5に示すような送り出し手段6と、を備えている。
【0025】
これら方法および装置により、ホルダ3がキャップ2を溜め置くホッパ4内でまたはホッパ4内に面して上動するように巡回されるとき、ホッパ4内でまたはホッパ4内に面して上動する間、ホッパ4内に溜められているキャップ2群と引っ掛かり合ってそれを掻き上げながら、上向きの受載部1で掬っていくことを繰り返す。この繰り返しにおいて、ホルダ3の受載部1はキャップ2のうち軸線方向Xが受載部1と直角でかつ軸線方向Xに非対称な特定の開口側2aが特定の側に向く特定物2Aを重心G上の鉛直線Zが受載部1から外れないように受載し、それ以外の向きの非特定物2Bは重心G上の鉛直線Zが受載部1から外れるように受載する上記のような選別断面形状および選別姿勢を持っていることによって、前記掬ったキャップ2が前記特定物2Aであった場合、その重心G上の鉛直線Zが受載部1から外れない安定な姿勢で受載することにより、ホッパ4内の他のキャップ2との干渉によっても脱落させずに持ち上げていき、前記掬ったキャップ2が前記非特定物2Bであった場合、その重心G上の鉛直線Zが受載部1から外れる不安定な姿勢に受載して、自重やホッパ4内の他のキャップ2との干渉によって振動なしに難なく落下させて特定物2Aとの入れ替わりを繰り返し図る。これらにより、特定物2Aだけ、つまり、軸線方向Xが受載部1と直角でかつ軸線方向Xに非対称な特定の一端である開口側2aが特定の側に向く特定物2Aだけを持上げてキャップ2の向きを確率よく選別することができ、しかも、この向きの選別を受載部1の全長に亘って同時に行なうので、受載部1の長さ、ホッパ4内でまたはホッパ4内に面してホルダ3が上動する距離、およびホッパ4内でまたはホッパ4内に面してホルダ3が上動する単位時間当たりの回数、に比例して選別効率が向上するので、キャップ2中の向きを選別した特定物2Aを簡単な方法および装置にて安価に不良品化なく単位時間当たり十分な供給量にて供給することができる。また、必要スペースも小さくてよい。しかも、キャップ2中の向きを選別した特定物2Aはホルダ3によって図1、図4〜図6に示す所定位置Sまで持上げホルダ3の一端側に送り出し、向きが揃ったままホルダ3から直接他に送り込めるので他への供給が簡単になる。
【0026】
ここで、ホルダ3のホッパ4内でのまたはホッパ4内に面しての上動の前段を、前記選別姿勢に比し特定物2Aの重心G上の鉛直線Zが受載部1のより内側となる図1、図4、図7(b)に示すような斜めになる準選別姿勢から図1、図4、図7(a)に示す直立した前記選別姿勢まで変化させて行なう。この準選別姿勢は図1、図4に示すような斜め経路に沿って移動することによる一定の斜め姿勢を保って移動するようにしてもよいし、円弧経路に沿って移動することによる傾斜角度が漸次変化しながら移動するようにもできる。
【0027】
要するに、受載部1が傾斜して重心G上の鉛直線Zが受載部1のより内側に寄った分だけ、特定物2Aおよび非特定物2Bとも所定の割合で受載部1に受載され持上げられやすくなるのを利用して、結果として特定物2Aが受載部1に受載され持上げられる割合を高めておいた後、ホルダ3を選別姿勢に変化させて特定物2Aのみ受載し続け、非特定物2Bのみ重心G上の鉛直線Zが受載部1から外れて自重で確実に落下させられるので、向きの選別効率をさらに高めて単位時間当たり供給量のさらなる増大を図ることができる。
【0028】
受載部1の具体的な断面形状は特に問わない。図10に示す例では、前記特定物2Aを下方より受ける受載壁1aと、この受載壁1aの背部で特定物2Aの軸線方向X一端に添わせる背面壁1bとを有した単純な鉤型の断面形状のものでも実線で示す特定物2Aの安定な受載姿勢と、仮想線で示す非特定物2Bの不安定な受載姿勢とで明らかなように十分である。
【0029】
これに対し図1〜図9に示す例では前記受載壁1aは背面壁1bと反対の側で立ち上がる選別フランジ1cを有し、背面壁1bとの間に上向きの溝1dを形成している。これにより、端部で外へ広がるテーパ状部分2bの有無など軸線方向端部での形状や大小の違いを、溝1dでの図9に示すような大きな部分の受入れ機能によって吸収して受載姿勢が特に変化しないようにし、選別フランジ1cによるキャップ2の支持点Pに対するキャップ2の重心G上の鉛直線Zの位置が受載部1側かどうかによって特定物2Aと非特定物2Bとをより選別しやすくするとともに、特定物2Aについては背面壁1bによるサポートにてより安定に受載できるようにするので、向き選別の確実性と汎用性を高めることができる。
【0030】
本実施の形態の装置は、さらに、図2に示す基台10の両端から立ち上がるように設けた側板11間の上下背部側に図1、図2、図4に示す駆動軸12および従動軸13を架設するとともに、下方前部側に今1つの従動軸14を架設し、これら各駆動軸12、従動軸13、14の一方の端部に設けたスプロケット15〜17に1本のチエン18を掛け回し、他方の端部に設けたスプロケット21〜23にも1本のチエン19を掛け回して巡回駆動機構5を構成している。これら各チエン18、19の間には前記ホルダ3を多数架設し、駆動軸12を駆動することによりチエン18、19を介しホルダ3をホッパ4内でまたはホッパ4内に面して上動する経路を持つように巡回駆動するようにしている。
【0031】
駆動軸12の駆動は通常モータにより駆動するが、使用規模によっては手動で駆動するようにもできる。手動による場合はハンドル方式を採用するのが好適である。しかし、駆動方式も特に問うものではない。ホッパ4は側板11の間でホルダ3の巡回経路前に沿って配した図1に示す邪魔板41とこれに対面して部品溜まり20と前記巡回経路に面した排出口25とを形成するように斜めに配した前面板26とで形成されているが、ホッパ4の具体的な構成も特に問わない。邪魔板41はホルダ3が受載した特定物2Aがホッパ4内のキャップ2群と徒に接触して落下してしまうのを防止する役目を営むが、必須でないのは勿論、設ける位置や範囲も種々に設定することができる。
【0032】
前記巡回経路は下方前部の従動軸14と上部の駆動軸12との間のチエン18、19をガイド27、28にて前部から後部に向けて押し込むことにより、ホルダ3が傾斜した軌跡を斜め姿勢で上動する経路と、ホルダ3を斜め姿勢から直立姿勢にまで変化させる姿勢切り換え経路と、ホルダ3が直立姿勢を保って垂直に上動する経路とを形成している。しかし、このような経路を作るためのガイド構造は特に問わない。
【0033】
送り出し手段6はホルダ3によって所定位置Sまで持上げた特定物2Aにエアを吹き付けてホルダ3の一端3aに向けて送り出すエアブロー手段としてある。具体的には図4に示すように、所定の停止位置にあるホルダ3のほぼ全長に亘って沿うブローノズル31が設けられ、これにブロア32がフィルタ30を通じて吸引し排出する送風を直接または必要に応じ設けるヘパフィルタ33を介し供給すると、ブローノズル31のホルダ3に対面する側にホルダ3の長手方向に多数設けられたブロー口31aからホルダ3上の特定物2Aに向け斜め前方にエアを吹き付け、ホルダ3の一端3a側に送り出せるようにしてある。
【0034】
このように、特定物2Aをそれと離れた位置から機械的には無接触に送り出すようにすると、送り出し手段6をキャップ2やホルダ3の巡回経路などとの干渉の問題なく容易に設置し働かせることができる。ブローノズル31は、また、図4に示すようにホルダ3の一端3aと逆の反送り出し側で下方に延びた補助ブロー部31bを有し、この補助ブロー部31bに所定の位置のホルダ3よりも1つ下、また2つ下のホルダ3上の特定物2Aの後部のものにも同様なエアの吹きつけを行なうようにしてある。このエアの吹き付けはこれら1つ下、また2つ下のホルダ3によって持上げられてきた特定物2Aにつきホルダ3の供給が行なわれる一端3aの側に前もって詰めておく前詰め作業のためであり、所定位置での供給作業上で特定物2A相互の間合いを詰める時間が不要になるので供給時間が短縮する。このような前詰め作業によって特定物2Aが所定位置に達するまでにホルダ3から送り出されてしまうのを防止するため、所定位置に達する前のホルダ3の一端3aは一定位置に固定して設けた簡単な邪魔板133によって常時閉じておくようにする。
【0035】
巡回駆動機構5はホルダ3を間欠に巡回させることにより、ホルダ3が停止と上動を繰り返すときの脈動により、ホルダ3および受載部1とホッパ4内のキャップ2との引っ掛かりを強めて受載状態が安定な特定物2Aの持ち上げ確率を上げながら、受載が不安定な非特定物2Bに対しては上動再開の都度働く慣性によって落下を促進するので、特定物2Aの持上げ効率をさらに高めることができるとともに、特定物2Aの送り出し位置を前記間欠な巡回方式によるホルダ3の所定の位置Sとすることにより、横長な1つのホルダ3によって多数の特定物2Aを向き選別して持上げ1箇所にて他に供給することがホルダ3の停止位置と停止時間とを利用して着実に達成することができる。
【0036】
図7(a)に示すキャップ2の寸法とホルダ3との好適な寸法関係の一例を示せば、下記の通りである。
【0037】
x<A÷2
x<d
y<50.8−B
x<C÷2
w<A
また、これをほぼ満足したキャップ2およびホルダ3の具体的な寸法関係を示すと、キャップ2についてはA=30mm、B=20.1mm、C=38mm、d=13mmである。これに対応するホルダ3についてはx=14mm(ここではdよりも大きいが、小さくしてもよい。)、y=32mm、z=15mm、w=17mmである。
【0038】
また、ホルダ3の好適な間隔R(図8)はR=18.8mmであり、選別フランジ1cの側の間隔R1(図8)はR=35.8mmとなる。これにより、特定物2Aが各ホルダ3の受載部1に入り込むことを保証しながら、図10に仮想線で示す向きの非特定物2Bが受載部1に入り込むのを阻止することができ、これによっても選別効率を向上することができる。もっとも、間隔R1が大きいほど特定物2A、非特定物2Bともに受載部1に入り込みやすくなるので、間隔R、R1はその時々に好適なように設定すればよい。
【0039】
本発明者等の実験によれば、上記のような条件設定によって600〜700/分の向き選別供給が達成できた。
【0040】
【発明の効果】
本発明の向き選別供給方法と装置によれば、ホルダが供給対象物を溜め置くホッパ内でまたはホッパ内に面して上動するように巡回されて、ホッパ内に溜められている供給対象物群のうち特定物だけを持上げて供給対象物の向きを確率よく選別することをホルダの全長に亘って同時に行なうことで、ホルダの長さ、ホッパ内でまたはホッパ内に面してホルダが上動する距離、および単位時間当たりの回数に比例して選別効率が向上し、必要スペースが小さい簡単な装置にて安価に不良品化なく単位時間当たり十分
な供給量にて供給することができる。また、特定物はエアを吹き付けて送り出し供給するので、特定物をそれと離れた位置から機械的には無接触に送り出せて干渉の問題がない。しかも、送り出し位置の下でのエアの吹き付けによる前詰めにより、送り出し位置で特定物相互の間合いを詰める時間が不要になるので供給時間が短縮する。

BACKGROUND OF THE INVENTION
The present invention relates to a direction sorting supply method and apparatus, and more particularly to a direction sorting supply method and apparatus for sorting and supplying a supply object that is asymmetric in the axial direction so that the directions of the ends in the axial direction are aligned. is there.
[0002]
[Prior art]
There are caps as a representative example of a supply object that is asymmetric in the axial direction. In order to automatically attach the caps to the container, the cap is supplied in a state where the opening side and the closing side of the cap are in the same direction in the axial direction.
[0003]
However, thin caps made of metal or synthetic resin often have a cylindrical surface with a straight outer peripheral surface. However, it is substantially asymmetric in the axial direction because one end side is open and the other end side is closed. It is difficult to align the opening side and the closing side of such caps so that they are in the same direction in the axial direction. Therefore, conventionally, it has become common to align and supply using a vibration feeder with good sorting performance.
[0004]
On the other hand, Japanese Utility Model Laid-Open No. 05-44912 (1) discloses an orientation selection and supply device for an asymmetric part in an axial direction in which one end side in the axial direction is open and the other end side is closed, such as a heat spreader having a shoulder. Yes. This is provided with a belt-like locking projection having a low height on an inclined sliding surface, and the component is dropped while applying vibration. While the part slides down, the part with the shoulder part facing down slides down to the lowest part while getting over the locking convex part at the shoulder part. A part with a flat surface facing downward cannot get over the locking projection, and is guided to the side groove along the slope set in the length direction of the locking projection and discharged.

Japanese Laid-Open Patent Publication No. 10-7241 (2) discloses an apparatus for conveying a shaft-shaped workpiece while being aligned in the axial direction while preventing the formation of a bridge. This is a conveyor that circulates diagonally upward facing the hopper, and is provided with claw portions for locking and transporting a shaft-shaped workpiece in two stages, front and rear, and the width of the front claw and The width of the nail and the arrangement pitch are set smaller than the arrangement pitch. In the front conveyor, the shaft-like work in the front hopper is scooped up and locked roughly by each claw, and a plurality of items are overlapped with each claw, but the work piece axial direction is in the longitudinal direction of the claw. Is transported in the locked state, and is put into the subsequent hopper one by one in order. The rear conveyor is a small amount of workpieces that are sequentially fed into the subsequent hopper in a state where the axial direction is aligned, and a small amount of the nail with a small width that does not overlap each other. By crawling up and locking with the claw, it is possible to convey and supply approximately the same amount as the amount supplied from the preceding conveyor.
[0006]
Japanese Laid-Open Patent Publication No. 2000-15185 (3) discloses a part determination and alignment method and apparatus for aligning cylindrical parts that are randomly delivered. This is a multi-stage push-up plate that pushes up components one by one on an inclined surface with a predetermined width and slides forward, from the hopper side to the conveyance path means, and the parts are intermittently arranged one by one on the conveyance path means. In the feeding and transport path means, the parts that are sent one by one in sequence are transported in the row direction and subjected to pass / fail judgment by image recognition and rejected defective products, and then rejected non-defective products, that is, the type and orientation of the parts It is possible to send out only items that have
[0007]
[Problems to be solved by the invention]
However, the vibration feeder is expensive and has a small supply amount per unit time, which is about 100 / min for PET bottle caps. For this reason, it cannot cope with the recent increase in the speed of the filling machine, and a plurality of vibration feeders are required for one filling line, which increases the equipment cost and occupies a large space. In addition, a cap with a so-called perforation, such as a cap of a PET bottle, has a problem that the perforation is inadvertently cut due to vibrations, resulting in a defective product.
[0008]
In the technique described in the publication (1), even if it can cope with a very flat cap, the larger the axial dimension, that is, the higher the height of the cap, the easier it is for a non-defective product to fall forward and the efficiency of selection. Will drop momentum. In addition, if the locking projections are provided in multiple stages in order to increase the supply amount by orientation selection, the position where the non-defective products are received and discharged by the respective locking projections is different. It is necessary to provide a means for collecting and supplying the selected directions so as not to disturb the selected directions. Moreover, there is a problem that the perforation of the cap is cut by the influence of vibration.
[0009]
In the technique described in the publication (2), even if the axial workpieces are aligned in the longitudinal direction of the claw, the one end side and the other end side are in the same direction in the axial direction with respect to the asymmetrical one in the axial direction. Sorting is not possible. The technique described in the publication (2) uses the fact that there is a large-diameter portion near the one end side of the workpiece to align the direction of the one end side and the other end side of the workpiece that is asymmetric in the axial direction. The large diameter portion of the workpiece is received by the opening edge of the groove by the apparatus, and the shaft portion on the long side from the large diameter portion is dropped into the groove. Accordingly, two types of sorting mechanisms are required, the structure is complicated and expensive, and the occupied space is large.
[0010]
In the technique described in the publication (3), a mechanism for aligning random parts in the hopper in a row, a transport path means for transporting the aligned parts in the row direction, and transport in the row direction by the transport path means The device is complicated and expensive because it requires a means for recognizing the orientation of the parts to be processed, a mechanism for removing defective products based on the result of image recognition, and a mechanism for returning the rejected defective products into the hopper. And the occupied space is large. In addition, there is a problem that the ratio of the non-defective products among the components finally arranged in a row is low and the supply amount per unit time cannot be obtained sufficiently.
[0011]
An object of the present invention is to supply a sufficient supply amount per unit time without defective products in order to select and supply the direction of the supply object asymmetric in the axial direction in the axial direction. The object is to provide an orientation sorting and supplying method and apparatus that can be performed in a small space.
[0012]
[Means for Solving the Problems]
  In order to achieve the object as described above, the orientation sorting and supply method of the present invention includes:To accept multiple supply objectsExtending in the lateral direction, SpecialSpecific facing the fixed sideMore thanNon-specific object facing outwardIs selfSorting by heavy dropFormBy rotating the holder so that the holder with the holder has a path that moves up in the hopper for storing the supply object or sequentially facing the hopper,IsSupply object in the hopperRaisingBeforeOnly specific items are acceptedAndPredeterminedSend outLift to positionRepeatedly, a specific object on the holder is blown to the holder by blowing air at the delivery position.Supply to the one end side with the same feeding directionAt the same time, the specific object on the holder below the predetermined position is pre-packed to be packed on one end side by blowing air.This is the main feature.
[0013]
  The device that achieves this has an upward-facing receiving part.To accept multiple supply objectsExtending in the lateral direction, SpecialSpecific facing the fixed sideMore thanNon-specific object facing outwardSelfFall by weightMakeA holder, a hopper for storing an object to be supplied, and a patrol drive mechanism for patroling the holder so as to have a path for sequentially moving up in the hopper or facing the hopperIn the orientation sorting and feeding device equipped with,
  An air blow means for sending a specific object on the holder to one end side by blowing air at a predetermined sending position and a position below it in a path along which the holder moves upward, and at one position, the one end side of the holder is opened and sent. There is provided a closing means that receives and packs the specific object that is sent by closing one end of the holder under the delivery position without disturbing the delivery of the specific object that is sent.This is the main feature.
[0014]
  In the configuration of these methods and devices,holderSupply is stored in the hopper while moving up in the hopper or in the hopper when it is circulated in the hopper for storing the supply object or moving up in the hopper Catch up with the object group and scrape it upRakuRepeatedlyDaSupply objectChitokuSpecific things that face the fixed sideReceivedNon-specific items placed in other directionsIs selfFall by weightMakeBy, SpecialIt is a regular thingTakePick up the direction of supply object with high probability.And the holderBecause it is performed simultaneously over the entire length ofholderIn proportion to the length of the hopper, the distance that the holder moves up in or facing the hopper, and the number of times the holder moves up in or facing the hopper Increased efficiencyAndA specific object whose orientation in the supply object is selected can be supplied at a sufficient supply amount per unit time at low cost with a simple method and apparatus having a small required space without being defective.In addition, since the specific object on the holder is blown and supplied to one end side of the holder at the delivery position, the specific object can be mechanically sent out from a position away from the specific object, and there is no problem of interference. Moreover, even when the specified object on the holder is blown to one end of the holder in advance by blowing air even under the delivery position, the time for filling the gap between the specified objects at the delivery position becomes unnecessary, so the supply time Is shortened.
[0016]
The receiving part has a receiving wall that receives the specific object from below and a back wall that is attached to one end in the axial direction of the specific object at the back of the receiving wall. The above-mentioned selection condition can be satisfied for a large dimension in the right-angle direction, and it can be realized at low cost.
[0017]
In this case, in addition, in the structure in which the receiving wall has a flange that rises on the side opposite to the back wall, and an upward groove is formed between the receiving wall and the back wall, the presence or absence of a tapered portion that extends outward at the end The difference in shape and size at the end in the axial direction is absorbed by the receiving function of the large part in the groove so that the receiving posture does not change in particular, and the supply object relative to the support point of the supply object by the selection flange is Depending on whether the position of the vertical line on the center of gravity is on the receiving part side, it is easier to select specific items and non-specific items, and specific items can be received more stably with support by the back wall, The certainty and versatility of orientation selection can be improved.
[0019]
The patrol drive mechanism patrols the holder intermittently, and the pulsation when the holder repeatedly stops and moves up strengthens the catch between the holder and the receiving part and the supply object in the hopper, and the receiving state is stable. While increasing the lifting probability of a specific object, it accelerates the fall by the inertia that works every time when upward movement is resumed for non-specific objects that are unstable in receiving, so that the lifting efficiency of a specific object can be further enhanced and specified By setting the delivery position of the object to a predetermined stop position of the holder by the intermittent patrol system, it is possible to select and feed a large number of specific objects by one horizontally long holder and supply it to the other at one place. It can be achieved steadily using the stop position and stop time.
[0020]
Further features of the present invention will become apparent from the following detailed description and drawings. Each feature of the present invention can be used alone or in combination in various combinations as much as possible.
[0021]
DETAILED DESCRIPTION OF THE INVENTION
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a direction selection and supply method and apparatus according to an embodiment of the present invention will be described in detail with reference to the drawings for understanding of the present invention.
[0022]
The present embodiment is an example of a method and apparatus for selecting and supplying a synthetic resin cap of a PET bottle. However, the present invention is not limited to this, and is effective when applied to a case in which the orientation in the axial direction is selected and supplied for a general supply object that is asymmetric in the axial direction, and these are also within the scope of the present invention. Belongs.
[0023]
The direction sorting and supplying method according to the present embodiment will be described with reference to the direction sorting apparatus shown in FIGS. 1 to 10. The upward receiving portion 1 extends in the lateral direction, and the cap 2 is a supply object. 4, 6, 7 (a), and FIG. 10 in which the opening side 2 a, which is a specific end that is perpendicular to the receiving portion 1 and is asymmetrical in the axial direction X, faces the specific side. 2A is received such that the vertical line Z on the center of gravity G does not deviate from the receiving portion 1, and the non-specific object 2B as shown in FIGS. The holder 3 having a sorting cross-sectional shape and a sorting posture in which the cap 2 is detached from the receiving portion 1 and falls due to its own weight faces the hopper 4 or the hopper 4 as shown in FIGS. By rotating the holder 3 so as to have a path that moves up sequentially, the holder 3 When moving up in the hopper 4, the cap 2 in the hopper 4 is lifted by the receiving portion 1 of the holder 3, and only the specific object 2A is received and lifted, and the specific object 2A is lifted to a predetermined position. Are fed to one end 3a of the holder 3 with the same orientation.
[0024]
In order to achieve this, the apparatus has a specific end that has the upward receiving portion 1 extending in the lateral direction and the axial direction X of the cap 2 is perpendicular to the receiving portion 1 and asymmetric with respect to the axial direction X as described above. The specific object 2A with the opening side 2a facing the specific side is received such that the vertical line Z on the center of gravity G does not deviate from the receiving part 1, and the non-specific object 2B in the other direction is on the center of gravity G. A holder 3 having a selected cross-sectional shape in which the vertical line Z of the vertical axis Z is removed from the receiving portion 1 and falls due to its own weight, a hopper 4 for storing the cap 2, and the holder 3 in the hopper 4 or in the hopper 4. 1 to 4 and the specific object 2A lifted up to a predetermined position by the holder 3 is sent out from one end 3a of the holder 3. And a delivery means 6 as shown in FIGS. .
[0025]
By these methods and devices, when the holder 3 is circulated in the hopper 4 for storing the cap 2 or so as to move up in the hopper 4, the holder 3 moves up in the hopper 4 or in the hopper 4. While doing so, it repeats that it is caught by the cap 2 group stored in the hopper 4 and scrambling it up with the upwardly receiving portion 1. In this repetition, the receiving portion 1 of the holder 3 has the center of gravity of the specific object 2A of the cap 2 in which the axial direction X is perpendicular to the receiving portion 1 and the specific opening side 2a that is asymmetric in the axial direction X faces the specific side. The vertical line Z on G is received so that it does not deviate from the receiving part 1, and the non-specific object 2B in the other direction is received so that the vertical line Z on the center of gravity G deviates from the receiving part 1. A stable posture in which the vertical line Z on the center of gravity G does not deviate from the receiving portion 1 when the cap 2 is the specific object 2A. In the case where the cap 2 is lifted without dropping due to interference with other caps 2 in the hopper 4, and the rolled cap 2 is the non-specific object 2B, the vertical on the center of gravity G The line Z is received in an unstable posture where it deviates from the receiving unit 1. , Without difficulty dropped without vibration by the interference with the other cap 2 of its own weight and hopper 4 achieved repeatedly replaced with a particular product 2A. Accordingly, only the specific object 2A, that is, the specific object 2A in which the axial direction X is perpendicular to the receiving portion 1 and the specific end asymmetrical to the axial direction X is directed to the specific side is lifted and the cap is lifted. 2 can be selected with a high probability, and since the selection of the direction is performed simultaneously over the entire length of the receiving portion 1, the length of the receiving portion 1, within the hopper 4 or within the hopper 4. Thus, the sorting efficiency is improved in proportion to the distance that the holder 3 moves up and the number of times per unit time that the holder 3 moves up or faces the hopper 4. The specific object 2A whose direction has been selected can be supplied at a sufficient supply amount per unit time without a defective product at a low cost by a simple method and apparatus. Also, the required space may be small. In addition, the specified object 2A whose orientation in the cap 2 is selected is sent to one end side of the lifting holder 3 by the holder 3 to a predetermined position S shown in FIGS. It is easy to supply to others.
[0026]
Here, the vertical line Z on the center of gravity G of the specified object 2A is higher than that of the receiving portion 1 in the preceding stage of the upward movement of the holder 3 in the hopper 4 or facing the hopper 4. It changes by changing from the semi-sorting attitude | position which becomes diagonal as shown in FIG.1, FIG.4, FIG.7 (b) used as an inner side to the said upright sorting attitude | position shown in FIG.1, FIG.4, FIG.7 (a). This semi-selection posture may be moved while maintaining a certain oblique posture by moving along an oblique path as shown in FIGS. 1 and 4, or an inclination angle by moving along an arc route. Can be moved while gradually changing.
[0027]
In short, both the specific object 2A and the non-specific object 2B are received by the receiving part 1 at a predetermined ratio by the amount that the receiving part 1 is inclined and the vertical line Z on the center of gravity G is closer to the inner side of the receiving part 1. As a result, the ratio of the specific object 2A being received and lifted by the receiving unit 1 is increased by using the fact that the specific object 2A is easily lifted. Since the vertical line Z on the center of gravity G is removed from the receiving part 1 and is surely dropped by its own weight only for the non-specific object 2B, the direction selection efficiency is further increased, and the supply amount per unit time is further increased. Can be planned.
[0028]
The specific cross-sectional shape of the receiving portion 1 is not particularly limited. In the example shown in FIG. 10, a simple wall having a receiving wall 1a for receiving the specific object 2A from below and a back wall 1b attached to one end in the axial direction X of the specific object 2A at the back of the receiving wall 1a. Even a mold having a cross-sectional shape is sufficient as apparent from the stable receiving posture of the specific object 2A indicated by the solid line and the unstable receiving posture of the non-specific object 2B indicated by the phantom line.
[0029]
On the other hand, in the example shown in FIGS. 1 to 9, the receiving wall 1a has a selection flange 1c that rises on the side opposite to the back wall 1b, and an upward groove 1d is formed between the back wall 1b. . As a result, the difference in shape and size at the end in the axial direction, such as the presence or absence of the tapered portion 2b extending outward at the end, is absorbed and received by the receiving function of the large portion as shown in FIG. 9 in the groove 1d. The particular object 2A and the non-specific object 2B are determined depending on whether the position of the vertical line Z on the center of gravity G of the cap 2 with respect to the support point P of the cap 2 by the selection flange 1c is on the receiving portion 1 side. In addition to facilitating sorting, the specific object 2A can be more stably received by the support by the back wall 1b, so that the certainty and versatility of orientation sorting can be improved.
[0030]
The apparatus of the present embodiment further has a drive shaft 12 and a driven shaft 13 shown in FIGS. 1, 2 and 4 on the upper and lower back sides between the side plates 11 provided so as to rise from both ends of the base 10 shown in FIG. In addition, one driven shaft 14 is installed on the lower front side, and one chain 18 is attached to each of the drive shafts 12 and sprockets 15 to 17 provided at one end of the driven shafts 13 and 14. The circulating drive mechanism 5 is configured by hanging one sprocket 19 to the sprockets 21 to 23 provided at the other end. A large number of the holders 3 are installed between the respective chains 18 and 19, and the holder 3 is moved up in the hopper 4 or facing the hopper 4 through the chains 18 and 19 by driving the drive shaft 12. It is made to drive around so as to have a route.
[0031]
The drive shaft 12 is normally driven by a motor, but may be driven manually depending on the scale of use. In the case of manual operation, it is preferable to adopt a handle method. However, the drive system is not particularly questioned. The hopper 4 forms a baffle plate 41 shown in FIG. 1 arranged between the side plates 11 along the circulation path of the holder 3, and forms a component reservoir 20 and a discharge port 25 facing the circulation path. However, the specific structure of the hopper 4 is not particularly limited. The baffle plate 41 serves to prevent the specific object 2 </ b> A received by the holder 3 from coming into contact with the cap 2 group in the hopper 4 and dropping, but it is not essential and of course the position and range to be provided. Can also be set in various ways.
[0032]
The circular path is formed by pushing the chains 18 and 19 between the lower front driven shaft 14 and the upper drive shaft 12 with the guides 27 and 28 from the front toward the rear, thereby causing the holder 3 to have an inclined trajectory. A path that moves up in an oblique position, a position switching path that changes the holder 3 from an oblique position to an upright position, and a path in which the holder 3 moves up vertically while maintaining the upright position are formed. However, the guide structure for making such a route is not particularly limited.
[0033]
The sending means 6 is an air blowing means that blows air toward the specific object 2 </ b> A lifted to a predetermined position S by the holder 3 and sends the air toward one end 3 a of the holder 3. Specifically, as shown in FIG. 4, a blow nozzle 31 is provided along substantially the entire length of the holder 3 at a predetermined stop position, and the blower 32 sucks and discharges through the filter 30 directly or necessary. Air is blown obliquely forward toward the specific object 2A on the holder 3 from a large number of blow ports 31a provided in the longitudinal direction of the holder 3 on the side facing the holder 3 of the blow nozzle 31. The holder 3 can be fed to the one end 3a side.
[0034]
In this way, when the specified object 2A is sent out from a position away from it, it is possible to easily install and operate the delivery means 6 without problems of interference with the cap 2 and the circulation path of the holder 3 or the like. Can do. As shown in FIG. 4, the blow nozzle 31 has an auxiliary blow part 31b that extends downward on the opposite side to the one end 3a of the holder 3, and the auxiliary blow part 31b has a holder 3 at a predetermined position. The air is blown to the rear part of the specific object 2A on the holder 3 which is one lower and two lower. This blowing of air is for a pre-packing operation in which the specific object 2A lifted by the holder 3 which is one lower or two lower is packed in advance on the side of the one end 3a where the holder 3 is supplied. Since the time for closing the gap between the specific objects 2A in the supply operation at the predetermined position is not required, the supply time is shortened. In order to prevent the specific object 2A from being sent out from the holder 3 before reaching the predetermined position by such a pre-packing operation, one end 3a of the holder 3 before reaching the predetermined position is fixedly provided at a fixed position. It is always closed by a simple baffle plate 133.
[0035]
The patrol drive mechanism 5 patrols the holder 3 intermittently, so that the holder 3 and the receiving portion 1 and the cap 2 in the hopper 4 are strongly caught by the pulsation when the holder 3 repeatedly stops and moves upward. While raising the lifting probability of the specific object 2A with a stable loading state, the non-specific object 2B with unstable loading promotes the fall by inertia that works every time when the upward movement is restarted, so the lifting efficiency of the specific object 2A is increased. In addition, the specific object 2A can be lifted by selecting and moving a large number of specific objects 2A by a single horizontally long holder 3 by setting the delivery position of the specific object 2A to a predetermined position S of the holder 3 by the intermittent circulation method. Supplying to another at one place can be achieved steadily using the stop position and stop time of the holder 3.
[0036]
An example of a suitable dimensional relationship between the dimensions of the cap 2 and the holder 3 shown in FIG. 7A is as follows.
[0037]
x <A ÷ 2
x <d
y <50.8-B
x <C ÷ 2
w <A
Further, a specific dimensional relationship between the cap 2 and the holder 3 that substantially satisfies the above is shown. For the cap 2, A = 30 mm, B = 20.1 mm, C = 38 mm, and d = 13 mm. For the holder 3 corresponding to this, x = 14 mm (here, larger than d, but may be smaller), y = 32 mm, z = 15 mm, and w = 17 mm.
[0038]
Moreover, the suitable space | interval R (FIG. 8) of the holder 3 is R = 18.8mm, and the space | interval R1 (FIG. 8) by the side of the selection flange 1c is R = 35.8mm. Accordingly, it is possible to prevent the non-specific object 2B having the orientation indicated by the phantom line in FIG. 10 from entering the receiving unit 1 while ensuring that the specific object 2A enters the receiving unit 1 of each holder 3. This also improves the sorting efficiency. However, since the specific object 2A and the non-specific object 2B are more likely to enter the receiving portion 1 as the distance R1 is larger, the distances R and R1 may be set to be suitable at that time.
[0039]
According to the experiments by the present inventors, the orientation selection supply of 600 to 700 / min could be achieved by setting the conditions as described above.
[0040]
【The invention's effect】
  According to the direction sorting supply method and apparatus of the present invention,The holder is circulated so as to move up in the hopper where the supply object is stored or facing the hopper, and only a specific object is lifted from the supply object group stored in the hopper to lift the supply object. By selecting the orientation with high probability at the same time over the entire length of the holder, it is proportional to the length of the holder, the distance the holder moves up in or facing the hopper, and the number of times per unit time. Sorting efficiency is improved and a simple device with a small required space is sufficient per unit time at low cost without defective products.
It is possible to supply with a sufficient supply amount. Further, since the specific object is supplied by blowing air, the specific object can be mechanically sent out from a position away from the specific object, and there is no problem of interference. In addition, the supply time is shortened because the time required to close the gap between the specific objects at the delivery position becomes unnecessary by the front-packing by blowing air under the delivery position.
