【産業上の利用分野】
本発明は正方形状の薄板の一辺に近接して片面側に厚肉部が形成され、対向する他片に近接して同じ片面側に中肉部が形成された部品、または中肉部が形成されていない部品について、移送の向きと表裏とを整えて移送すると同時に、部品に伴われてくる破損片を排除する部品整送装置に関するものである。
【０００２】
【従来の技術及びその問題点】
図１は整送対象としての部品Ｍの斜視図であり、正方形の薄板の隣り合う二隅に厚肉部Ｈ、これと対向する二隅に中肉部Ｌが形成されており、中肉部Ｌの外側の隅は切り欠かかれている。そして、図１に示す姿勢、すなわち厚肉部Ｈ、中肉部Ｌを上にした表向きの姿勢で、白抜き矢印の方向、すなわち２個の厚肉部Ｈが接して形成されている辺の方向へ移送することの要請がある。また、図２は部品Ｍに伴われる二つ割れした破損片ｍを示す斜視図であり、割れ方によって図２のＡ、Ｂ、Ｃ、Ｄに示すように、破損片ｍａ、ｍｂ、ｍｃ、ｍｄがある（これらを総称する場合は破損片ｍとする）。そのほか、図２には示さずとも形状的に更に小さい細片ｓも含まれてくるが、部品Ｍを整送する途中でこれら破損片ｍ、細片ｓを排除することが望まれている。
【０００３】
本発明者等に部品Ｍの整送装置を開発するに当り、捩り振動パーツフィーダのボウルに取り付ける整送トラックに破損片排除穴を設けることにして、当初は図１９に示すような整送トラック２０１を作製した。図１９は整送トラック２０１の整送方向に直角な断面図であり、図２０はその部分拡大図である。そして、これらの図は後述する実施例の整送トラック１０１の整送方向に直角な断面図である図１３、およびその部分拡大図である図１４に対応している。整送トラック２０１はボウル２２１の周縁部２２９上にトラックブロック２０２を固定し、これに垂下部２１１ｔを備えた抑えプレート２１１とガイドプレート２０６とを取り付けて形成されており、整送面２０４の幅は部品Ｍの一辺の長さより僅か大とされている。そして整送面２０４の中央部には整送方向に長い破損片排除孔２２３が形成されており、その底面は破損片用のトラック２２４となっている。
【０００４】
整送トラック２０１の上流側において所定の移送の向きでない部品Ｍが排除され裏向きの部品が排除されて、表向きで所定の移送の向きにある部品Ｍが２個の厚肉部が形成されている辺を外周側にして整送トラック２０１内へ送り込まれ、厚肉部Ｈと中肉部Ｌとの中間に抑えプレート２１１の垂下部２１１ｔが挿入されて位置決めされ整送されるようになっている。そして、部品Ｍは底面の外周側部分と内周側部分とで破損片排除穴２２１を跨いで下流端まで整送されて排出され、破損片ｍや細片ｓは破損片排除穴２２１へ落下して排除され底面のトラック２２４を移送されて下流端から排出されるようになっている。
【０００５】
この整送トラック２０１を備えた部品整送装置を部品Ｍの整送、破損片ｍと細片ｓの排除に実使用する中で、破損片ｍ、細片ｓの排除が十分でなく、部品Ｍ中に破損片ｍの混入するトラブルを生じた。
【０００６】
【発明が解決しようとする問題点】
本発明は上述の問題に鑑みてなされ、正方形状の薄板の一辺に近接して片面側に厚肉部が形成され、対向する他辺に近接して同じ片面側に中肉部が形成された部品、または中肉部が形成されていない部品について、移送の向きと表裏とを整えて移送すると同時に、部品に伴われてくる破損片を確実に排除し得る部品整送装置を提供することを目的とする。
【０００７】
【問題点を解決するための手段】
以上の目的は、正方形状の薄板の一辺に近接して片面側に厚肉部が形成され、対向する他辺に近接して前記片面側に中肉部が形成された部品、または前記中肉部が形成されていない部品について、前記厚肉部を上に向けた表向きで、前記厚肉部の形成されている辺を移送方向に向けて整送し、かつ前記部品に伴われてくる前記部品の破損片を排除する捩り振動パーツフィーダにおいて、そのボウルに設置された、前記厚肉部の形成されている辺を移送方向に向けている前記部品のみを通過させ、それ以外の移送の向きの前記部品は排除する移送の向き選別部、および表向きの前記部品を通過させ裏向きの前記部品は排除する表裏選別部の下流側に位置して、前記ボウルの径外方へ向かって上向き傾斜の整送面、これに直角な狭幅の整送底面、前記整送面と所定の間隙を有して平行な抑え部材、およびその外周側に取り付けられたガイド部材とによって前記整送面の幅を前記部品の一辺の長さより僅か大として断面がほぼ長方形のトンネル状とされており、表向きの前記部品が前記厚肉部の形成されている辺を外周側にし移送方向に向けて移送される整送トラックと、前記整送面の中流部分に設けられ、伴われてくる前記部品の破損片を落下させ排除するための、前記整送トラック内にある前記部品がその底面の外周側部分と内周側部分とで跨ぎ得る幅で移送方向に長い破損片排除穴とからなる整送・破損片排除部が設けられており、前記抑え部材の下面にはその上流部分の外周側において前記部品の前記厚肉部が移送され得る間隙を形成し、前記上流部分の内周側において前記厚肉部は移送され得ず、前記薄板と前記中肉部、または前記薄板は移送され得る間隙を形成する導入ガイド部が設けられており、前記破損片排除穴の直上から下流端までは前記導入ガイド部が欠落されて、前記破損片の内、前記部品と同様に表向きで前記厚肉部外周側にして移送されてくる二つ割れしたような破損片も前記破損片排除穴上において捩り振動によって移送方向に配向されて前記破損片排除穴へ落下することを特徴とする部品整送装置、によって達成される。
【０００８】
【作用】
捩り振動パーツフィーダのボウルに設けた移送の向き選別部と表裏選別部を経由して表向きで所定の移送の向きとされた部品はボウルの径外方へ向かって上向き傾斜の整送トラックの整送面において、抑え部材の下面に設けられている導入ガイドによって、部品の厚肉部の形成されている辺を外周側に保持して整送され、破損片排除穴を底面の外周側部分と内周側部分とで跨いで落下することなく整送され下流端から排出される。一方、破損片の大部分は破損片排除穴へ落下するが、破損片の中でも部品と同様に表向きで厚肉部を外周側にして移送されて、排除されにくい二つ割れの破損片は破損片排除穴の直上方から下流側へかけて抑え部材の導入ガイドが欠落されていることにより、捩り振動を受けて自由に移送方向に配向されて破損片排除穴へ落下し排除される。
【０００９】
【実施例】
以下、本発明の実施例による部品整送装置について図面を参照して説明する。図３は実施例の部品整送装置１００の平面図であり、図４は図３における［４］−［４］線方向の断面図である。すなわち、部品整送装置１００は図４を参照して皿状のボウル２１と、これに捩り振動を与える駆動部１１とからなっている。
【００１０】
駆動部１１においては、ボウル２１の底部をボルト１９で一体的に固定した可動ブロック１２が等角度間隔に配置した傾斜板ばね１３によって下方の固定ブロック１４と連結されており、固定ブロックの１４上にはコイル１５を巻装した電磁石１６が可動コアを兼ねる可動ブロック１２と僅かの間隙をあけ対向して設けられている。駆動部１１の周囲は防音カバー１７で覆われており、駆動部１１はボウル２１と共に防振ゴム１８を介して床面に設置されている。そして、コイル１５に交流が通電されることにより、ボウル２１に捩り振動が与えられ、図３で見てボウル２１内に収容されている部品Ｍは矢印ｐで示す反時計方向に移送されるようになっている。
【００１１】
ボウル２１には図４に示すように、ボウル２１の径外方へ向かって上向き４５度傾斜の移送面２４とこれに直角な狭幅の底面２５とからなるトラック２３が底面２２の起点２３ｓからスパイラル状に上昇して設けられている。そして部品Ｍは移送面２４に傾倒し、四辺の何れかを底面２５に接して移送される。トラック２３の途中には欠乏検知センサ３１が設けられ、最上部の周回には多列で移送されてくる部品Ｍを単列化するはね板４１、早出しゲート５１が設けられている。また、約１／４周を占める最下流部においては、ボウル２１の周縁部２９に固定した外付けブロック６１と共にボウル２１の周縁部２９を平坦化して部品Ｍの移送の向き選別トラック７１、表裏選別トラック８１、最終選別トラック９１、整送トラック１０１が順に形成され、整送トラック１０１内に破損片排除穴１２１が設けられている。以下、これらについて説明する。
【００１２】
欠乏検知センサ３１は発光素子と受光素子を内蔵する光センサ３２が、図３における［５］−［５］線方向の断面図である図５に示すようにボウル２１の周縁部２９にボルト３３ｂで固定したサポート３３に取り付けられてトラック２３上の部品Ｍを監視しており部品Ｍの移送が所定秒数以上検知されない場合には、図示しない貯蔵ホッパを駆動して部品Ｍを補充する。
【００１３】
はね板４１は図３、及び図３における［６］−［６］線方向の断面を示す図６を参照して、トラック２３の移送面２４に沿って固定される取付け部４２と移送面２４に垂直に捻られたガイド部４３とからなり、トラック２３の底面２５とガイド部４３との間はテーパ状に狭められてその下流端部では部品Ｍが単列で移送される間隔とされている。すなわち、多列で移送されてくる部品Ｍを単列化させ、余剰の部品Ｍはガイド部４３に導かれてボウル２１内へ戻される。なお、取付け部４２はそれ自身の長穴を挿通するボルト４２ｂによって取り付けられており、ガイド板４３と底面２５との間隔は調整可能となっている。
【００１４】
また、はね板４１の下流側に設けられている早出しゲート５１は図３における［７］−［７］線方向の断面を示す図７を参照して、移送面２４に開けた穴５２を塞いでゲート板５３が移送面２４と整合して設けられ、ボルト５４ｂで固定されている。すなわち緊急時、ないしはボウル２１内に必要以上の部品Ｍがあって、部品Ｍを系外へ取り出す時にボルト５４ｂをゆるめゲート板５３を上方へスライドさせて穴５２へ落下させる。すなわち、定常時には使用されない。
【００１５】
移送の向き選別トラック部７１は、図３における［８］−［８］線方向の断面を示す図８を参照して、ボウル２１の周縁部２９を切り込んで平坦化した表面上にトラックブロック７２を置き、この外周側に外付けブロック６１がボルト６１ｂで固定されている。トラックブロック７２にはボウル２１の径外方へ向いて上向き２０度傾斜の移送面７４とこれに直角な狭幅の底面７５とが設けられ、トラックブロック７２の内周側には、下面が移送面７４に平行で移送面７４とは間隙をあけた張出し部７６を有する抑えプレート７７がボルト７７ｂで固定されている。この間隙は部品Ｍの中肉部Ｌは余裕を持って挿入されるが厚肉部Ｈは挿入されない高さとされ、かつ底面７５からの張り出し長さは中肉部Ｌの形成されている辺が底面７５に接して移送される長さとされている。このようにして形成される断面が傾斜したコ字形状のトンネルとして移送の向き選別トラック７１が設けられている。なお、抑えプレート７７の上流端部においては張出し部７６の幅を狭めて部品Ｍが移行され易くしている。
【００１６】
そして、上流側の傾斜角４５度の移送面２４とトラックブロック７２上の傾斜角２０度の移送面７４を繋ぐために、それらの間に下流側へ向かって下向き傾斜の移送面２６が設けられている。
【００１７】
すなわち、部品Ｍは移送面２４上に表裏を混在させたまま傾倒され、かつ底面２５に接する辺を一定させないまま、換言すれば移送の向きがランダムなまま上流側のトラック２３から移送されてくるが、移送の向き選別トラック７１においては、厚肉部Ｈの形成されている辺を外周側にして傾倒した部品Ｍのみが中肉部Ｌを移送の向き選別トラック７１内へ挿入して中肉部Ｌの形成されている辺を底面７５に接し、厚肉部Ｈを抑えプレート７７の張出し部７６の外側に位置させて移送されるが、それ以外の向きの部品Ｍは移送の向き選別トラック７１内へ入り込むことなく移送される。
【００１８】
また、図３、および図３における［９］−［９］線方向の断面を示す図９を参照して、トラックブロック７２は外周側を切り欠いて戻し面２７が形成されており、移送の向き選別トラック７１へ入り得ずに移送面７４にある部品Ｍは戻し面２７へ落下しボウル２１内へ還流されるようになっている。すなわち、外付けブロック６１を切り欠いて戻し面２７と一体的に戻し面６２が形成され、更には戻し面６２に設けたポケット６８_１と、これに接続される戻し面２７のポケット２８_１はトラックブロック７２の下方を経由してボウル２１内へ通じており、ボウル２１の内面に開口２８ｅが設けられている。なお、下流側にも同様なポケット６８_２、２８_２が形成されている。
【００１９】
更には、表裏選別トラック８１は図３を参照し、鋸歯状移送面として形成されている。すなわち、トラックブロック７２上の移送面７４は図９に示す幅から狭められ、図３の平面図で見て後述するワイパ８８の下方で抑えプレート７７の張出し部７６に隠れる幅とされた後、下流側へ向かってテーパ状に拡げられ、再びボウル２１の径方向に沿って急激に狭めた第１鋸歯状移送面８１_１（移送面７４と兼用されている）と、これに続く同様な第２鋸歯状移送面８１_２が形成されている。図３における［１０］−［１０］線方向の断面を示す図１０を参照し、第２鋸歯状移送面８１_２においては、移送の向き選別トラック７１内に中肉部Ｌを挿入してはいるが裏向きである部品Ｍは第２鋸歯状移送面８１_２の幅が狭められた箇所において実線で示すように厚肉部Ｈを第２鋸歯状移送面８１_２の外方へ落とした姿勢となるが、同移送面８１_２の幅が下流側へ向かって拡げられると、厚肉部Ｈが同移送面８１_２の外周側端部に係止された状態となっていることから、一点鎖線で示すように漸次外周側へ引き出され第２鋸歯状移送面８１_２の下流端から下方の戻し面２７へ落下して選別される。勿論、上流側の第１鋸歯状移送面８１_１でも同様である。
【００２０】
ワイパ８８は抑えプレート７７に固定して幅の狭められた移送面７４上にかぶさるように、移送面７４との間を積み重ならない部品Ｍのみが通過し得る間隙をあけて設けられている。すなわち、中肉部Ｌを移送方向選別トラック７１内に挿入し、厚肉部Ｈが抑えプレート７７の張出し部７６の外側にある部品Ｍの厚肉部Ｈに積み重なって移送されてくる部品Ｍはワイパ８８の下方を通過し得ず、ワイパ８８の上流側端面に導かれてポケット２８_１、ないしは戻し面２７へ落下し排除される。
【００２１】
最終選別トラック９１は表裏選別トラック８１を通過後もなお残る正規の姿勢以外の部品Ｍ、例えばなお残る裏向きの部品Ｍや、その他、所定の姿勢ではあるが、移送の向き選別トラック７１から飛び出し気味に移送されてくる部品Ｍを排除するものであり、図３における［１１］−［１１］線方向の断面を示す図１１に示されている。すなわち、トラックブロック７２が元の幅に拡げられ、移送面７４の幅を部品Ｍの一辺の長さより僅かに大として、その外周側にガイドプレート９２をボルト９２ｂで固定して最終選別トラック９１が形成されており、最終選別トラック９１へ入り得ない部品Ｍは下方の戻し面２７へ落下してボウル２１内へ戻される。
【００２２】
最終選別トラック９１の下流側に接して整送トラック１０１が設けられている。図３における［１２］−［１２］線方向の断面を示す図１２を参照して、ボウル２１の周縁部２９上にトラックブロック１０２が周縁部２９の下面からボルト１０２ｂで固定され、上流側の移送面７４、底面７５と整合する整送面１０４、整送底面１０５が形成されている。なお、排除する部品Ｍは発生しないので、外付けブロック６１は延在されていない。また、トラックブロック１０２の内周側には抑えプレート１１１がねじ１１１ｂで固定して取り付けられ、整送面１０４の幅を部品Ｍの一辺の長さより僅かに大として外周側にガイド板１０６がねじ１０６ｂで固定して取り付けられている。更には図３における［１３］−［１３］線方向の断面を示す図１３も参照して、整送面１０４には整送方向に長い破損辺排除穴１２１が形成されており、破損片ｍをその下方の破損片トラック１２４へ落下させ排除するようになっている。整送面１０４が傾斜面とされているので整送トラック１０１内を整送される部品Ｍは中肉部Ｌの形成されている辺を整送底面１０５に接し位置決めされるので、破損片排除穴１２１は従来例の部品Ｍが位置きめされない場合の破損片排除穴２２１より幅を広く形成することが可能である。従って破損片ｍ、細片ｓは排除され易い。
【００２３】
上記の抑えプレート１１１と破損片排除穴１２１との関係は図１３の部分拡大部である図１４、および図１３における［１５］−［１５］線方向の矢視図に示されている。すなわち、図１５のＡは抑えプレート１１１を含む矢視図であり、図１５のＢは抑えプレート１１１を取りはずした矢視図である。抑えプレート１１１は下面の上流部分における外周側に部品Ｍの厚肉部Ｈを通過させる間隙高さを確保し、内周側は厚肉部Ｈが通過し得ず、中肉部Ｌは通過し得る間隙高さとする導入ガイド部１１２が設けられている。そしてこの導入ガイド部１１２は破損片排除穴１２１の上方から下流端へかけて欠落されており、部品Ｍの厚肉部Ｈの位置決めをはずしている。
【００２４】
更にはまた、整送トラック１０１の整送面１０４には破損片排除穴１２１の下流側で、整送面１０４と整送底面１０５とのコーナ部に位置して移送方向に長い細片排除穴１２５が下流端まで設けられており、上記コーナ部を移送されてくる細片ｓを破損片ｍと共通の破損片トラック１２４へ落下させ排除するようになっている。なお、整送トラック１０１の内周側となるボウル２１内のトラック２３の移送面２４にはガイド２４ｇが設けられ、ボウル２１の周縁部に設けられている切り欠き部２９ｗへ部品Ｍが移送されることを防いでいる。
【００２５】
本発明の実施例による部品整送装置１００は以上のように構成されるが、次にその作用を説明する。
【００２６】
図３、図４を参照し、ボウル２１の底面２２に表裏ランダムのまま多数に収容されている部品Ｍ（図３には示していない）は捩り振動を受けることにより、中央部の起点２３ｓからトラック２３へ乗り、その移送面２４に多列に傾倒し、矢印ｐで示す方向へ移送され始める。すなわち、部品Ｍは表裏不定で、移送の向きも不定のままトラック２３をスパイラル状に上昇する。
【００２７】
部品Ｍは先ず欠乏検知センサ３１の下方を通過するが、部品Ｍの移送が所定秒数以上途切れた場合にのみ図示しない貯蔵ホッパを駆動させるものであるから、部品Ｍが間断なく移送されている場合には特に何等の作用も起こらない。
【００２８】
次いで、はね板４１を通過することにより、移送面２４を多列で移送されて来た部品Ｍは単列化されて移送される。また、はね板４１の下流側には早出しゲート板５１が設けられているが、これは定常時には使用されない。
【００２９】
更には、図８を参照し、傾斜角４５度の移送面２４に傾倒し、移送されてくる部品Ｍは続く移送方向へ向かって下がり傾斜の移送面２６を滑落し、移送の向き選別トラック７１が設けられているトラックブロック７２の傾斜角２０度の移送面７４へ移行される。移送の向き選別トラック７１においては移送面７４と抑えプレート７７との間隙は部品Ｍの中肉部Ｌは入り得るが厚肉部Ｈは入り得ない高さとされているので、厚肉部Ｈの形成されている辺を外周側にして傾倒している部品Ｍは中肉部Ｌを移送の向き選別トラック７１内へ挿入し底面７５に接して移送されるようになるが、移送の向きがそれ以外の部品Ｍ、すなわち厚肉部Ｈの形成されている辺を内周側にしている部品Ｍや厚肉部Ｈの形成されている辺を移送方向と直交させている部品Ｍは移送の向き選別トラック７１内へ中肉部Ｌを挿入することなく移送され、図３、図９を参照して、下流側において移送面７４の幅が狭められることにより、下方の戻し面２７、ないしはこれと一体的な外付けブロック６１の戻し面６２へ落下して排除され、更にはポケット６８_１、２８_１を経由してボウル２１内へ還流される。
【００３０】
部品Ｍの破損片ｍも移送されてくるが、このうち、図２に示す中肉部Ｌのみの破損片ｍｄは勿論であるが、厚肉部Ｈと中肉部Ｌを持つ破損片ｍａ、ｍｂの中で中肉部Ｌを移送の向き選別トラック７１内へ挿入したものは排除されることなく移送される。厚肉部Ｈのみの破損片ｍｃは移送の向き選別トラック７１内へ入り得ずに移送面７４から下方の戻し面２７へ落下する。
【００３１】
移送面７４が狭められることにより、移送される部品Ｍは移送の向き選別トラック７１内に中肉部Ｌを挿入して底面７５に接し、厚肉部Ｈを外周側にした表向き、または裏向きの部品Ｍとなるが、更にはワイパ８８の下方を通過することによって、移送される部品Ｍの厚肉部Ｈの上に積み重なって移送されてくる部品Ｍや破損片ｍがあると、これらはワイパ８８の下方を通過し得ず、ワイパ８８の上流側端面に導かれて下方のポケット２８_１へ排除され、ワイパ８８を通過した部品Ｍは積み重なりがなく、中肉部Ｌを移送方向選別トラック７１内へ挿入し、厚肉部Ｈを外周側に位置させた表向き、又は裏向きの部品Ｍとなる。
【００３２】
更には図３のワイパ８８の直下から下流側への第１鋸歯状移送面８１_１、および図１０にも示す第２鋸歯状移送面８１_２からなる表裏選別トラック８１を通過する時に、移送面７４の幅が狭められている箇所において、表向きの部品Ｍは何等の作用を受けないが、裏向きの部品Ｍと裏向きの破損片ｍａ、ｍｂは厚肉部Ｈを第１鋸歯状移送面８１_１、第２鋸歯状移送面８１_２（何れも移送面７４と兼用されている）の外方へ落とす。そして第１鋸歯状移送面８１_１、第２鋸歯状移送面８１_２の幅が漸次拡げられることにより、裏向きの部品Ｍ、裏向きの破損片ｍａ、ｍｂは外周側へ引き出され、第１鋸歯状移送面８１_１、第２鋸歯状移送面８１_２の下流端から下方の戻し面２７へ落下して排除され、表裏選別トラック８１の下流側において移送されるのは、表向きで所定の移送の向きを取っている部品Ｍ、表向きの破損片ｍａ、ｍｂ、及び中肉部Ｌのみを有する表向き、裏向きの破損片ｍｄとなる。
【００３３】
次いで上記の部品Ｍ、破損片ｍは図１１に示す最終選別トラック９１へ移送されるが、最終選別トラック９１においてはガイドプレート９２が外周側に設けられているので、飛び出し気味に移送されてくる部品Ｍや破損片ｍ、およびなお残る裏向きの部品Ｍや破損片ｍは最終選別トラック９１へ入り得ずに下方へ落下して戻し面２７へ排除される。
【００３４】
最終選別トラック９１に続く整送トラック１０１においては図１２を参照し、表向きの部品Ｍは抑えプレート１１１の導入ガイド部１１２に介助され厚肉部Ｈを外周側にして移送される。また、厚肉部Ｈを外周側にした表向きの破損片ｍａ、ｍｂも同様に移送され、中肉部Ｌのみの破損片ｍｄは自由な向きで移送される。そして、図１４、図１５を参照し、部品Ｍは整送面１０４に形成されている破損片排除穴１２１へ到るが、所定の移送の向きの部品Ｍは底面の外周側部分と内周側部分とで破損片排除穴１２１を跨いで移送されて破損片排除穴１２１を通過し、下流端から表向きで所定の移送の向きで排出される。
【００３５】
一方、厚肉部Ｈを外周側にした破損片ｍａ、ｍｂは破損片排除穴１２１の上方で導入ガイド部１１２が欠落されているので、図１５のＢに実線および一点鎖線で示すように捩り振動によって破損片排除穴１２１の方向に沿う横向きにオリエンテーションされて破損片排除穴１２１へ落下し、下方の破損片トラック１２４上を移送され下流端から排除される。勿論、整送トラック１０１内で自由な向きにある破損片ｍｄは容易に破損片排除穴１２１へ落下する。
【００３６】
また、部品Ｍに同伴される細片ｓは整送面１０４と整送底面１０５とのコーナー部を移送されるが、これらの細片ｓ図１６、図１７を参照し、搬送トラック１０１の下流端部においてコーナー部に設けられている細片排除穴１２５から下方へ落下し、破損片ｍと共通の破損片トラック１２４へ集められ下流端から排除される。
【００３７】
以上のようにして、本実施例の部品整送装置によって部品Ｍは表向きで所定の移送の向きで排出され、部品Ｍに伴われる細片ｓは勿論のこと、破損品ｍも確実に排除され、部品Ｍへの混入は全く発生しない。
【００３８】
以上、本発明の実施例について説明したが、勿論、本発明はこれに限られることなく、本発明の技術的思想に基づいて種々の変形が可能である。
【００３９】
例えば、本実施例においては整送トラック１０１における抑えプレート１１１の下面の上流部分に導入ガイド部１１２を設けて部品Ｍの厚肉部Ｈを外周側に保持し、破損片排除穴１２１の上方では導入ガイド部１１２を欠落させて、二つ割れのような大きい破損片ｍａ、ｍｂも確実に排除されるようにしたが、整送トラック１０１自体を導入ガイド部１１２を有する部分と導入ガイド部１１２を欠落させた部分とに分割してもよい。
【００４０】
また、本実施例においては表裏選別部として、第１と第２の鋸歯状移送面８１_１、８１_２を有する表裏選別トラック８１を採用したが、これ以外の表裏選別手段、例えば、表向きの部品Ｍと裏向きの部品Ｍとで断面のプロフィールが異なることを利用するトンネル状の表裏選別トラックを用いてもよいし、その他の方法も採用し得る。
【００４１】
また、本実施例においては移送の向き選別部として、部品Ｍの中肉部Ｌが挿入される間隙を設けた断面が傾斜コ字形状の移送の向き選別トラック７１を採用したが、これ以外の移送の向き選別手段、例えば断面がＶ字形状でその底に沿って部品Ｍの中肉部Ｌは落下するが厚肉部Ｈは落下しない幅のスリットを設け、厚肉部Ｈで懸吊される部品Ｍと懸吊されない部品Ｍとに選別するＶ溝トラックを用いてもよいし、その他の方法も採用し得る。

Objective.
[0007]
[Means for solving problems]
The above purpose is a component in which a thick part is formed on one side near one side of a square thin plate, and a middle part is formed on one side near the opposite side, or the inner wall For parts not formed with a part, the thick part is faced up, the side where the thick part is formed is fed in the transfer direction, and the part is accompanied by the part. In a torsional vibration parts feeder that eliminates broken pieces of parts, only the parts that are installed in the bowl and in which the side where the thick-walled portion is formed are directed in the transfer direction are passed, and the other transfer directions The part of the bowl is located at the downstream side of the transfer direction sorting part for removing the front part and the part for passing the front side and the face-down sorting part is removed, and is inclined upward toward the outer diameter of the bowl. , And the narrow bottom surface perpendicular to this, The width of the adjusting surface is made slightly larger than the length of one side of the component by a holding member parallel to the adjusting surface with a predetermined gap and a guide member attached to the outer periphery thereof, and the cross section is substantially rectangular. And a rectifying track in which the part facing up is transferred toward the transfer direction with the side where the thick part is formed as an outer peripheral side, and provided in the middle portion of the rectifying surface. In order to drop and eliminate the broken pieces of the parts that accompany the parts, the parts in the transporting truck have a width that can be straddled between the outer peripheral part and the inner peripheral part of the bottom surface and are long in the transport direction. There is provided a squeeze / damaged piece exclusion portion comprising a piece exclusion hole, and a lower surface of the holding member forms a gap through which the thick portion of the component can be transferred on the outer peripheral side of the upstream portion, The thick wall on the inner peripheral side of the upstream portion The thin plate and the middle portion, or the thin plate is provided with an introduction guide portion that forms a gap where the thin plate and the thin plate can be transferred. The broken pieces that are transferred to the outer peripheral side of the thick-walled portion are also transferred by torsional vibration on the broken piece removal hole. This is achieved by a component feeder that is oriented in the direction and drops into the broken piece exclusion hole.
[0008]
[Action]
The parts of the torsional vibration parts feeder that have a predetermined transfer direction face up through the transfer direction selector and front / back selector provided on the bowl of the torsional vibration parts feeder are aligned on the feed truck that is inclined upward toward the outer diameter of the bowl. On the feeding surface, the introduction guide provided on the lower surface of the restraining member holds the side where the thick part of the part is formed on the outer circumferential side, and feeds the broken piece exclusion hole to the outer circumferential side portion of the bottom surface. The sheet is fed and discharged from the downstream end without falling across the inner peripheral portion. On the other hand, most of the broken pieces fall into the broken piece exclusion hole, but the broken pieces that are difficult to be removed are damaged because they are transported face-to-face and with the thick-walled part on the outer peripheral side, just like parts. Due to the lack of the introduction guide of the restraining member from directly above to the downstream side of the piece exclusion hole, it is subjected to torsional vibration and is freely oriented in the transport direction and dropped into the broken piece removal hole and eliminated.

That is, the component M is tilted with the front and back sides mixed on the transfer surface 24, and the side in contact with the bottom surface 25 is not fixed. In other words, the component M is transferred from the upstream track 23 with the transfer direction being random. However, in the transfer direction selection track 71, only the part M tilted with the side where the thick portion H is formed as the outer peripheral side is inserted into the transfer direction selection track 71 and the medium thickness portion L is inserted. The side on which the portion L is formed is in contact with the bottom surface 75 and the thick portion H is suppressed and is transferred to the outside of the overhanging portion 76 of the plate 77. It is transferred without entering into 71.
[0018]
Further, referring to FIG. 3 and FIG. 9 showing a cross section in the [9]-[9] line direction in FIG. 3, the track block 72 is notched on the outer peripheral side, and a return surface 27 is formed. The part M on the transfer surface 74 cannot enter the direction sorting truck 71 and falls to the return surface 27 and is returned to the bowl 21. That is, the external block 61 is cut out to form a return surface 62 integrally with the return surface 27, and further, a pocket 68 provided on the return surface 62. ₁ And a pocket 28 of the return surface 27 connected thereto. ₁ Passes through the track block 72 and into the bowl 21, and an opening 28 e is provided on the inner surface of the bowl 21. A similar pocket 68 is also provided on the downstream side. ₂ , 28 ₂ Is formed.
[0019]
Furthermore, the front and back sorting track 81 is formed as a sawtooth transfer surface with reference to FIG. That is, the transfer surface 74 on the track block 72 is narrowed from the width shown in FIG. 9, and the width is hidden below the overhanging portion 76 of the holding plate 77 below a wiper 88 described later with reference to the plan view of FIG. 3. A first sawtooth-shaped transfer surface 81 which is expanded in a tapered shape toward the downstream side and is sharply narrowed again along the radial direction of the bowl 21. ₁ (Also used as the transfer surface 74) and the subsequent second serrated transfer surface 81 ₂ Is formed. Referring to FIG. 10 showing a cross section in the [10]-[10] line direction in FIG. 3, the second sawtooth transfer surface 81. ₂ In FIG. 2, the part M which is inserted in the inside direction L in the transfer direction selection track 71 but facing backward is the second serrated transfer surface 81. ₂ As shown by the solid line in the portion where the width of the second portion is reduced, the thick portion H is moved to the second sawtooth-shaped transfer surface 81. ₂ However, the transfer surface 81 ₂ Is widened toward the downstream side, the thick wall portion H becomes the transfer surface 81. ₂ The second serrated transfer surface 81 is gradually drawn out to the outer peripheral side as indicated by a one-dot chain line. ₂ This is dropped from the downstream end to the lower return surface 27 and sorted. Of course, the first serrated transfer surface 81 on the upstream side. ₁ But the same is true.
[0020]
The wiper 88 is fixed to the holding plate 77 so as to cover the transfer surface 74 having a narrow width, and is provided with a gap through which only the part M that does not stack with the transfer surface 74 can pass. That is, the part M that is inserted into the transport direction sorting track 71 and is transferred to the thick part H of the part M outside the overhanging part 76 of the plate 77 is transferred by inserting the middle part L into the transfer direction sorting track 71. The pocket 28 cannot pass under the wiper 88 and is guided to the upstream end surface of the wiper 88. ₁ Or dropped to the return surface 27 and eliminated.
[0021]
The final sorting truck 91 jumps out from the sorting truck 71 in the transfer direction although it is in a predetermined posture, such as a part M other than the normal posture still remaining after passing through the front and back sorting truck 81, for example, the remaining part M facing back. The part M which is transported in an unobtrusive manner is excluded, and is shown in FIG. 11 which shows a cross section in the [11]-[11] line direction in FIG. That is, the track block 72 is expanded to the original width, the width of the transfer surface 74 is slightly larger than the length of one side of the component M, and the guide plate 92 is fixed to the outer peripheral side with the bolts 92b, so that the final sorting track 91 is The part M that is formed and cannot enter the final sorting truck 91 falls to the lower return surface 27 and is returned into the bowl 21.
[0022]
A feeding truck 101 is provided in contact with the downstream side of the final sorting truck 91. Referring to FIG. 12 showing a cross section in the [12]-[12] line direction in FIG. 3, the track block 102 is fixed on the peripheral edge 29 of the bowl 21 with a bolt 102b from the lower surface of the peripheral edge 29, and on the upstream side. A feeding surface 104 and a feeding bottom surface 105 aligned with the transfer surface 74 and the bottom surface 75 are formed. Since the parts M to be eliminated are not generated, the external block 61 is not extended. Further, a holding plate 111 is fixedly attached to the inner peripheral side of the track block 102 with screws 111b, and the guide plate 106 is screwed to the outer peripheral side with the width of the feeding surface 104 slightly larger than the length of one side of the part M. It is fixedly attached at 106b. Further, referring also to FIG. 13 showing a cross section in the [13]-[13] line direction in FIG. 3, a broken side exclusion hole 121 long in the feeding direction is formed in the feeding surface 104, and the broken piece m Is dropped to the broken piece track 124 below the same to be removed. Since the feeding surface 104 is an inclined surface, the part M to be fed through the feeding track 101 is positioned with the side where the inner wall portion L is formed in contact with the feeding bottom surface 105, so that broken pieces are eliminated. The hole 121 can be formed wider than the broken piece removal hole 221 when the conventional component M is not positioned. Therefore, the broken piece m and the strip s are easily removed.
[0023]
The relationship between the holding plate 111 and the broken piece exclusion hole 121 is shown in FIG. 14 which is a partially enlarged portion of FIG. 13 and in the arrow view in the [15]-[15] line direction in FIG. 15A is an arrow view including the restraining plate 111, and FIG. 15B is an arrow view with the restraining plate 111 removed. The restraining plate 111 secures a gap height that allows the thick part H of the component M to pass on the outer peripheral side in the upstream portion of the lower surface, and the thick part H cannot pass through the inner peripheral side, and the middle part L passes through. An introduction guide portion 112 having a gap height to be obtained is provided. And this introduction guide part 112 is missing from the upper part of the broken piece exclusion hole 121 to the downstream end, and positioning of the thick part H of the part M is removed.
[0024]
Further, the stripping surface 104 of the stripping track 101 is located downstream of the broken piece removal hole 121 and is located at a corner portion of the feeding surface 104 and the feeding bottom surface 105 and is long in the transfer direction. 125 is provided to the downstream end, and the strips s transported through the corner portion are dropped on the broken piece track 124 common to the broken piece m to be removed. A guide 24g is provided on the transfer surface 24 of the track 23 in the bowl 21 on the inner peripheral side of the feeding track 101, and the component M is transferred to a notch 29w provided on the peripheral edge of the bowl 21. To prevent that.
[0025]
The component feeder 100 according to the embodiment of the present invention is configured as described above. Next, the operation thereof will be described.
[0026]
3 and 4, a large number of parts M (not shown in FIG. 3) accommodated in a random manner on the bottom surface 22 of the bowl 21 are torsionally oscillated from the starting point 23 s in the center. The vehicle rides on the truck 23, tilts in multiple rows on the transfer surface 24, and begins to be transferred in the direction indicated by the arrow p. That is, the parts M are indefinite and the track 23 is raised in a spiral shape with the direction of transfer being indefinite.
[0027]
The part M first passes below the deficiency detection sensor 31. However, since the storage hopper (not shown) is driven only when the transfer of the part M is interrupted for a predetermined number of seconds or more, the part M is transferred without interruption. In some cases, no action occurs.
[0028]
Next, by passing through the splash plate 41, the parts M transferred in multiple rows on the transfer surface 24 are transferred to a single row. An early gate plate 51 is provided on the downstream side of the spring plate 41, but this is not used in a steady state.
[0029]
Further, referring to FIG. 8, it is inclined to the transfer surface 24 having an inclination angle of 45 degrees, and the component M to be transferred is lowered toward the subsequent transfer direction and slides down the inclined transfer surface 26, and the transfer direction selection track 71. Is moved to a transfer surface 74 having an inclination angle of 20 degrees. In the transfer direction selection track 71, the gap between the transfer surface 74 and the restraining plate 77 is set to a height at which the middle part L of the part M can enter but the thick part H cannot enter. The part M that is tilted with the formed side as the outer peripheral side is moved in contact with the bottom surface 75 by inserting the middle part L into the transfer direction selection truck 71, but the transfer direction is Other parts M, that is, the part M in which the side on which the thick part H is formed is the inner peripheral side, or the part M in which the side on which the thick part H is formed are orthogonal to the transfer direction It is transported into the sorting truck 71 without inserting the middle thickness portion L, and referring to FIGS. 3 and 9, the width of the transport surface 74 is narrowed on the downstream side, so that the lower return surface 27 or this Dropped onto the return surface 62 of the integrated external block 61 and eliminated , And even pocket 68 ₁ , 28 ₁ And then refluxed into the bowl 21.
[0030]
A broken piece m of the part M is also transferred. Of these, the broken piece md having only the middle portion L shown in FIG. Of the mb, the medium portion L inserted into the transfer direction selection track 71 is transferred without being excluded. The broken piece mc of only the thick part H cannot fall into the transfer direction selection track 71 and falls from the transfer surface 74 to the lower return surface 27.
[0031]
When the transfer surface 74 is narrowed, the component M to be transferred is inserted into the transfer direction selection track 71 so as to be in contact with the bottom surface 75 and the thick portion H on the outer side, or face-down. However, if there are parts M or broken pieces m that are transported by being stacked on the thick part H of the parts M to be transported by passing below the wiper 88, these are: The lower pocket 28 cannot pass under the wiper 88 and is guided to the upstream end face of the wiper 88. ₁ The part M that has passed through the wiper 88 is not stacked, and the middle part L is inserted into the transfer direction selection track 71 and the thick part H is positioned on the outer peripheral side, or the part M facing front or back. It becomes.
[0032]
Further, a first serrated transfer surface 81 from the position immediately below the wiper 88 in FIG. 3 to the downstream side. ₁ And a second serrated transfer surface 81 also shown in FIG. ₂ In the portion where the width of the transfer surface 74 is narrowed when passing through the front / back sorting truck 81, the front-side component M does not receive any action, but the back-side component M and the back-side damaged piece ma, mb designates the thick-walled portion H as the first serrated transfer surface 81. ₁ Second serrated transfer surface 81 ₂ (Both are also used as the transfer surface 74). The first serrated transfer surface 81 ₁ Second serrated transfer surface 81 ₂ Is gradually widened, the back-facing part M and the back-side damaged pieces ma and mb are pulled out to the outer peripheral side, and the first serrated transfer surface 81 is drawn. ₁ Second serrated transfer surface 81 ₂ Are dropped to the lower return surface 27 from the downstream end, and are transferred on the downstream side of the front and back sorting truck 81 in a part M that is facing the predetermined direction of transfer, a broken piece ma facing the front, It becomes the broken piece md of the front and back which has only mb and the inside part L.
[0033]
Next, the parts M and the broken pieces m are transferred to the final sorting truck 91 shown in FIG. 11. However, since the guide plate 92 is provided on the outer peripheral side in the final sorting truck 91, the parts M and the broken pieces m are transferred out. The part M and the broken piece m, and the remaining back-facing part M and broken piece m cannot fall into the final sorting truck 91 and fall down and are removed to the return surface 27.
[0034]
With reference to FIG. 12, in the transporting truck 101 subsequent to the final sorting truck 91, the component M facing up is assisted by the introduction guide part 112 of the restraining plate 111 and transferred with the thick part H as the outer peripheral side. Further, the front-facing broken pieces ma and mb with the thick portion H on the outer peripheral side are also transferred in the same manner, and the broken piece md of only the middle thickness portion L is transferred in a free direction. 14 and 15, the component M reaches the broken piece removal hole 121 formed on the feeding surface 104, but the component M in a predetermined transfer direction has an outer peripheral side portion and an inner peripheral portion of the bottom surface. It is transported across the broken piece exclusion hole 121 with the side portion, passes through the broken piece removal hole 121, and is discharged from the downstream end in a predetermined transfer direction.
[0035]
On the other hand, the broken pieces ma and mb having the thick wall portion H on the outer peripheral side are twisted as shown by the solid line and the alternate long and short dash line in FIG. Due to the vibration, it is oriented sideways along the direction of the broken piece removal hole 121 and falls to the broken piece removal hole 121, and is transported on the broken piece track 124 below and removed from the downstream end. Of course, the broken piece md in the free direction in the transporting truck 101 easily falls into the broken piece removal hole 121.
[0036]
Further, the strip s accompanying the part M is transferred at the corners of the feeding surface 104 and the feeding bottom surface 105. These strips s are downstream of the conveying track 101 with reference to FIGS. At the end, it falls downward from the strip exclusion hole 125 provided in the corner portion, and is gathered to the broken piece track 124 common to the broken piece m and removed from the downstream end.
[0037]
As described above, the component feeding device according to the present embodiment discharges the component M face-up and in a predetermined transfer direction, and not only the strip s accompanying the component M but also the damaged item m is reliably removed. No mixing into the part M occurs.
[0038]
As mentioned above, although the Example of this invention was described, of course, this invention is not restricted to this, A various deformation | transformation is possible based on the technical idea of this invention.
[0039]
For example, in this embodiment, an introduction guide portion 112 is provided in the upstream portion of the lower surface of the restraining plate 111 in the transporting track 101 to hold the thick portion H of the component M on the outer peripheral side, and above the broken piece removal hole 121. The introduction guide portion 112 is omitted, and large broken pieces ma and mb such as two cracks are surely removed. However, the feeding track 101 itself includes the portion having the introduction guide portion 112 and the introduction guide portion 112. You may divide | segment into the part which made it lack.
[0040]
In this embodiment, the first and second sawtooth transfer surfaces 81 are used as the front and back sorting portions. ₁ , 81 ₂ The front and back sorting truck 81 having the above is adopted, but other front and back sorting means, for example, a tunnel-shaped front and back sorting truck that utilizes the fact that the cross-sectional profile differs between the front-facing part M and the back-facing part M is used. Alternatively, other methods may be employed.
[0041]
Further, in the present embodiment, the transfer direction selection track 71 having a cross-sectionally U-shaped cross section provided with a gap into which the inner portion L of the component M is inserted is adopted as the transfer direction selection portion. A direction selection means for transfer, for example, a V-shaped cross-section, along which the middle part L of the part M falls, but the thick part H does not fall and is provided with a slit of a width that is suspended by the thick part H. A V-groove track for selecting a part M to be suspended and a part M not to be suspended may be used, and other methods may be employed.
[0042]
Further, in this embodiment, a part in which a thick part is formed on one side near one side of a square-shaped thin plate and a middle part is formed close to the other opposing piece is taken up. A part N having a shape obtained by removing the middle portion L from the part M as shown in FIG. 18A illustrating the shape of the part to which the part feeding device of the embodiment can be applied. ₁ , A part N in which only the thick part H ′ is formed over one side as shown in FIG. ₂ Further, as shown in FIG. 18C, a part N in which a cylindrical thick part H ″ is formed at the central part of one side and a cylindrical thick part L ″ is formed at the central part of the other piece. ₃ Can be transported and the broken pieces can be eliminated.
[0043]
【The invention's effect】
As described above, according to the component feeder of the present invention, a thick portion is formed on one side near one side of a square thin plate, and a middle portion is formed near the opposite side. It is possible to arrange the transferred parts or the parts in which the inner wall portion is not formed with the direction of transfer and the front and back of the parts and transfer them, and to reliably remove the broken pieces accompanying the parts. In particular, since the feeding surface of the feeding track is inclined in the width direction, the width of the broken piece removal hole can be set wider than when the parts are positioned in the width direction and the feeding surface is not positioned horizontally. . Therefore, as a result, broken pieces and fine pieces are surely dropped. In addition, an introduction guide portion is provided in the upstream portion of the lower surface of the holding plate of the transporting track, and the broken piece removal hole is missing from the upper end to the downstream end, so that a large broken piece such as a double crack is also oriented. It is surely eliminated and no contamination of parts occurs. .
