【発明の属する技術分野】
本発明は、主に上面開放容器内に収容された農作物の取出処理に使用される容器内収容物の反転取出装置に関する。
【０００２】
【従来の技術】
農作物の収容された上面開放容器を支持するための水平支持部と、この水平支持部の前端から起立させた垂直支持面部とを有するＬ字型反転枠を定置本体部に左右向き軸回りの揺動駆動可能に装着してなる容器内農作物の反転取出装置は存在している。
【０００３】
この取出装置により前記上面開放容器内からその収容物である農作物を取り出すときは、前記Ｌ字型反転枠を左右向き軸回りへ揺動させて、その垂直支持面部を前下がり状となすのであり、これにより上面開放容器内の農作物は重力作用により上面開放容器内からその外方へ転がり落ちるものとなる。
【０００４】
【発明が解決しようとする課題】
上記した在来の容器内農作物の反転取出装置の使用においては、農作物が取り出された後の上面開放容器を水平支持部から地上などに降ろす処理は手作業により行われているのが実情であり、この手作業に要する労力は、その取り扱う上面開放容器の数が多いほど多大なものとなる。
本発明は上記手作業を出来るだけ機械化することにより容器内収容物の取出に要する労力を減少させるものとした容器内収容物の反転取出装置を提供することを目的とする。
【０００５】
【課題を解決するための手段】
上記目的を達成するため、本願発明に係る第１の容器内収容物の取出装置では、請求項１に記載したように、垂直支持面部１５と水平支持部１４を備えたＬ字型反転枠６を備え、前記水平支持部１４は左右向きのローラ１７を前後方向に複数並設したものとなされており、前記水平支持部１４の前端から起立された垂直支持面部１５は上端部付近に適当間隔を置いて一対の係止爪２８ａ、２８ｂを支持面ｆ上に対する出没可能に設けられると共に上部の左右両端部を定置本体部４に対し左右向き軸５回りの反転揺動可能に装着されており、前記垂直支持面部１５と前記定置本体部４との間には前記Ｌ字型反転枠６の左右向き軸５回りの揺動に連動して前記係止爪２８ａ、２８ｂを出没作動させる係止爪作動手段２９を形成し、該係止爪作動手段２９は前記係止爪２８ａ、２８ｂを出側へ付勢するスプリング３６と、前記定置本体部４に結合され前記係止爪２８ａ、２８ｂを前記スプリング３６の弾力に抗しつつ没側へ押し変位させる押圧部材３９とを具備し、前記Ｌ字型反転枠６がこれの基準位置ｄ１と収容物取出位置ｄ２との間で揺動される過程において、前記垂直支持面部１５が前上がり傾斜姿勢となる特定揺動位置ｄ３から収容物取出位置ｄ２までの範囲では前記押圧部材３９が前記係止爪２８ａ、２８ｂを連動変位させないことにより前記係止爪２８ａ、２８ｂが前記スプリング３６の付勢力で完全に出側へ変位された状態となり、一方前記Ｌ字型反転枠６が前記基準位置ｄ１から前記特定揺動位置ｄ３に到達する前の一定揺動位置までの範囲では前記押圧部材３９が前記係止爪２８ａ、２８ｂを没側へ連動変位させることにより前記係止爪２８ａ、２８ｂが完全に没側へ変位された状態となる作動を起こさせるものとなされており、完全に出側へ変位された状態の前記係止爪２８ａ、２８ｂは前記水平支持部１４に載せられた上面開放容器の側面の前記垂直支持面部１５と対接する上縁部に係合して前記支持面ｆ上での上面開放容器の前記水平支持部１４の支持平面と直交する方向の変位を規制する構成を特徴としている。
【０００６】
この発明において、水平支持部１４の左右向きのローラ１７は上面開放容器を前後方向から水平支持部１４に移動し載置する処理を容易となし、また係止爪作動手段２９が係止爪２８ａ、２８ａを出側へ付勢するスプリング３６を具備することは係止爪２８ａ、２８ａをスプリング３６の弾力で出側へ変位させることを可能となし、また係止爪作動手段２９が押圧部材３９を具備することはＬ字型反転枠６の左右向き軸５回りの位置に対応して係止爪２８ａ、２８ａを特定位置に安定的に位置決めするように連動させることを可能となし、またＬ字型反転枠６がこれの基準位置ｄ１と収容物取出位置ｄ２との間で揺動される過程で垂直支持面部１５が前上がり傾斜姿勢となる特定揺動位置ｄ３から収容物取出位置ｄ２までの範囲で係止部材２８ａ、２８ａを完全に出側へ変位させた状態になすこと、及び、完全に出側へ変位された状態の係止爪２８ａ、２８ａは水平支持部１４に載せられた上面開放容器の側面の垂直支持面部１５と対接する上縁部に係合して支持面ｆ上での上面開放容器の水平支持部１４の支持平面と直交する方向の変位を規制することは、Ｌ字型反転枠６が反転された状態の下で上面開放容器をＬ字型反転枠６上に位置保持して、上面開放容器内の収容物を重力作用で落下させる上で寄与するものであり、また垂直支持面部１５が前記基準位置から前記特定揺動位置に到達する前の一定揺動位置までの範囲で係止部材２８ａ、２８ａを完全に没側へ変位させた状態となすことは、Ｌ字型反転枠６が基準位置ｄ１に位置する前にＬ字型反転枠６上の上面開放容器を地上などに落下させたりＬ字型反転枠６上に次の上面開放容器を載置する処理を係止爪２８ａ、２８ａの影響を受けることなく円滑に行うことを可能となす。
【０００７】
本願発明に係る第２の容器内収容物取出装置は、請求項２に記載したように、垂直支持面部１５と水平支持部１４を備えたＬ字型反転枠６を備え、前記水平支持部１４は左右向きのローラ１７を前後方向に複数並設したものとなされており、該水平支持部１４の前端から起立された垂直支持面部１５はこれの上端部付近に適当間隔を置いて棒部材からなる左右一対の係止爪２８ａ、２８ａを支持面ｆ上に対する出没可能に設けられると共に上部の左右両端部を定置本体部４に対し左右向き軸５回りの反転揺動可能に装着されており、前記垂直支持面部１５と前記定置本体部４との間には前記Ｌ字型反転枠６の左右向き軸５回りの揺動に連動して前記係止爪２８ａ、２８ａを出没作動させる係止爪作動手段２９が形成されており、前記係止爪２８ａ、２８ａは、前記Ｌ字型反転枠６がその特定揺動位置ｄ３とその収容物取出位置ｄ２との間に揺動されたときに、前記係止爪作動手段２９により完全に出側へ変位されると共に、その基準位置ｄ１と、前記特定揺動位置ｄ３よりも前記基準位置ｄ１に近いその揺動位置との間に揺動されたときに前記係止爪作動手段２９により没側に変位されるものとなされ且つ、完全に出側へ変位されたときには前記水平支持部１４に載せられた上面開放容器の側面の前記垂直支持面部１５と対接する上縁部に入り込むように係合して前記垂直支持面部１５上での前記水平支持部１４の支持平面と直交する方向の上面開放容器の変位を規制するようになり、一方、没側に位置されたときには前記上面開放容器に係合しないように作動する構成となされており、また前記水平支持部１４に載せられた空状態の上面開放容器を前記Ｌ字型反転枠６の揺動変位過程の特定位置で左右方向へ落下させるものとした容器放出機構４４が設けてあり、該容器放出機構４４は容器押上揺動部材４５と押上力付与機構４６とを備えており、前記容器押上揺動部材４５は前記水平支持部１４に載せられた上面開放容器を支持し左右傾斜状に押し上げるために前記水平支持部１４に前後向き支点軸４９を介して左右傾斜変位可能に装着された左右向き棒部材４７を具備しており、前記押上力付与機構４６は前記左右向き棒部材４７を左右傾斜変位させるための特定大きさの押上げ力を付与するスプリング５８を具備すると共に前記Ｌ字型反転枠６がその基準位置ｄ１に位置したときに前記左右向き棒部材４７を前記スプリング５８の押上げ力に抗して水平化させ前記ローラ１７よりも下方に位置させるものとなされており、また前記Ｌ字型反転枠６が空状態の上面開放容器を支持した状態で且つ、前記係止爪２８ａ、２８ａが出側に位置され上面開放容器の上縁部に入り込んでいる状態で且つ、前記容器押上揺動部材４５が前記押上力付与機構４６の押上げ力を上面開放容器の底面に付与している状態の下で、前記Ｌ字型反転枠６が前記収容物取出位置ｄ２側から前記特定揺動位置ｄ３よりも前記基準位置ｄ１に近いその揺動位置に位置されることにより、前記係止爪２８ａ、２８ａが没側に変位されて、上面開放容器の前記水平支持部１４の支持平面と直交する方向の変位が許容され、該許容に関連して前記左右向き棒部材４７は前記スプリング５８の押上げ力で左右傾斜状態となり、該左右向き棒部材４７で支持された空状態の上面開放容器は、該左右向き棒部材４７上を重力作用により左右方向へ滑り降下される構成を特徴としている。
【０００８】
この発明において、水平支持部１４の左右向きのローラ１７の存在や、Ｌ字型反転枠６がその基準位置ｄ１に位置したときに左右向き棒部材４７を水平化させてローラ１７よりも下方に位置させることは、上面開放容器を前後方向から水平支持部１４に移動し載置する処理を容易となすのであり、また係止爪２８ａ、２８ａが出側へ変位されたときに該係止爪２８ａ、２８ａが水平支持部１４に載せられた上面開放容器の側面の垂直支持面部１５と対接する上縁部に係合し垂直支持面部１５上での水平支持部１４の支持平面と直交する方向の変位を規制する構成となされていることはＬ字型反転枠６が反転された状態の下で上面開放容器をＬ字型反転枠６上に位置保持し上面開放容器内の収容物を重力作用で落下させる上で寄与するものであり、また容器押上揺動部材４５が水平支持部１４に載せられた上面開放容器を支持して左右傾斜状に押し上げるために水平支持部１４に前後向き支点軸４９を介して左右傾斜変位可能に装着された左右向き棒部材４７を具備しており且つ、押上力付与機構４６が左右向き棒部材４７を左右傾斜変位させるための特定大きさの押上げ力を付与するスプリング５８を具備することは、左右向き棒部材４７と出状態の係止爪とでＬ字型反転枠６上の上面開放容器を安定的に位置保持する上で寄与するのであり、またＬ字型反転枠６が空の上面開放容器を支持して基準位置ｄ１の近傍に位置したときで係止爪２８ａ、２８ａが没状態となったとき左右向き棒部材４７はスプリング５８の押上げ力で左右傾斜状態となり且つ、該左右向き棒部材４７で支持された空の上面開放容器が該左右向き棒部材４７上を重力作用により左右方向へ滑り降下されることは、Ｌ字型反転枠６が基準位置ｄ１に位置したとき空の上面開放容器は水平支持部１４上には存在しておらず、直ちに、収容物の収容された次の上面開放容器を水平支持部１４上に載置することを可能となすほか、Ｌ字型反転枠６上の空の上面開放容器を人為力を要することなく迅速に地上などに落下させることを可能となす。

【００１４】
図１に示すように、本発明に係る容器内収容物取出装置は、主要部１、搬送物係止機構付ローラコンベア２及び水平ローラコンベア３からなっている。
先ず、主要部１について図１〜図７を参照して説明する。
図１に示すように、主要部１は定置本体部４と、これに左右向き軸５を介して上下揺動可能に支持されたＬ字型反転枠６とを備えている。
前記定置本体部４は左右に前後向きとなされて配置された図６に示す一対の水平脚部７、７のそれぞれから前後向きの垂直支持壁部８、８を起立させると共に、左右の垂直支持壁部８、８間の特定高さ位置に前下がり状の案内板部材９を固設し、また左右の垂直支持壁部８、８の前側に上面開放容器ａであるバスケット内から取り出された収容物を受け入れて滞留させるための収容物受入部１０を形成し、さらにこの受入部１０の前側には動力で駆動され収容物受入部１０内に滞留している収容物を順次に外方へ搬出するものとしたバケットコンベア１１を傾斜状に配設したものとなされている。
【００１５】
この際、収容物受入部１０は図２に示すように前記各垂直支持壁部８、８を前方へ延長させた側面壁部１２、１２と前記案内板部材９を側面壁部１２、１２間の前方へ延長させて形成された案内板延長部９ａと、前記バケットコンベア１１とで周囲を囲まれたものとなされており、またバケットコンベア１１は左右向きのバケット１３の多数を前上がり傾斜面ｂに沿わせて連続的に上方へ向け移動させ、このように移動される各バケット１３が収容物受入部１０内に滞留している多数の収容物を少しづつ掬い上げて前上方へ搬送し、搬出口ｃから落下させることを繰り返すものとなされている。
【００１６】
前記Ｌ字型反転枠６は図２〜図４などに示すように水平支持部１４と、この水平支持部１４の前端部から起立させた垂直支持面部１５とを備えている。そして、水平支持部１４は四角枠部材１６の内方の左右各側に３つの左右向きのローラ１７を前後方向に並列させて支持平面を形成したものとなし、また垂直支持面部１５は四角枠部材１８を有すると共に前記四角枠部材１８の左右各端部を上方へ延長した態様のアーム部１８ａ、１８ａを有し、これら四角枠部材１８及びアーム部１８ａ、１８ａの後端面に板部材１９を被着したものとなしてある。この際、前記左右向き軸５近傍となる板部材１９部分の左右２箇所には縦長の透孔ｊ、ｊを形成される。
【００１７】
前記左右向き軸５は左右のアーム部１８ａ、１８ａの上部間に橋渡し状に固定されると共に、図６に示すように左右の各端部を垂直支持壁部８、８のそれぞれの後端面の高さ途中に固定された軸受部２０、２０を介して回動可能に支持される。
【００１８】
そして、図３、図４及び図６に示すように、Ｌ字型反転枠６と前記定置本体部４との間にはＬ字型反転枠６を左右向き軸５回りへ揺動させるための駆動機構２１が設けてある。この駆動機構２１は定置本体部４側に固定された駆動本体部２２と、この駆動本体部２２の左右側面から突出した状態の左右向き出力軸２３とＬ字型反転枠６とを結合したリンク機構部２４とを備えている。
【００１９】
この際、駆動本体部２２は内部にモータを具備し、このモータの出力軸と前記左右向き出力軸２３とを歯車伝動機構で連動連結したものとなされている。またリンク機構部２４は左右向き出力軸２３の左右各端部に固定された出力アーム２５、２５と、このアーム２５、２５の先端部に一端を枢着され他端を垂直支持面部１５の四角枠部材１８の左右向き部材１８ｂの左右箇所に固着された結合片２６、２６に枢着された結合棒部材２７、２７とからなっている。
【００２０】
上記した駆動機構２１は、駆動本体部２２内のモータが回転されることにより出力アーム２５、２５が左右向き出力軸２３回りへ揺動駆動され、この出力アーム２５、２５の揺動変位が結合棒部材２７、２７を介してＬ字型反転枠６に伝達され、この伝達により、Ｌ字型反転枠６が図１に仮想線で示す基準位置ｄ１と、実線で示す収容物取出位置ｄ２との間範囲ｅ内で左右向き軸５回りの正逆方向へ揺動変位されるように構成したものである。
【００２１】
また図３、図４、図６及び図７に示すように、Ｌ字型反転枠６の垂直支持面部１５と前記定置本体部４の左右向き軸５近傍箇所との間には、前記水平支持部１４に載せられた上面開放容器ａの前面に係合される左右一対の係止爪２８ａ、２８ａを必要時に前記垂直支持面部１５の支持面ｆに対して出没作動させるものとした係止爪作動手段２９が設けてある。
この係止爪作動手段２９は水平支持部１４に装着される係止爪機構３０と、この係止爪機構３０を動作させるもので定置本体部４の左右向き軸５近傍箇所に装着された押圧力付与機構３１と、前記係止爪機構３０の動作を制限するもので定置本体部４の左右向き軸５近傍箇所に設けられた制限機構３２からなっている。
【００２２】
前記係止爪機構３０は、垂直支持面部１５の左右向き部材１８ｂの左右各側箇所に前方視Ｕ字形の軸受板部材３３、３３を固着し、一方では左右向き辺部２８ｂの左右端部から縦向き辺部２８ｃ、２８ｃを延出させると共に各縦向き辺部２８ｃの先端を前側へ屈曲させてこの屈曲箇所よりも前側を係止爪２８ａとなした係止爪棒部材２８を形成し、前記左右向き辺部２８ｂを前記一対の軸受板部材３３、３３の軸孔ｇに回動自在に挿通させ、また左右の縦向き辺部２８ｃ、２８ｃの比較的元部の相互間箇所に門形棒部材３４を架設状に固着すると共に、各縦向き辺部２８ｃの略中央箇所に９０度曲がり状の係合棒部材３５を固着し、さらに右側の係合棒部材３５の左右向き部とその対応する軸受板部材３３との間に引張スプリング３６を架け渡した構成となしてある。
【００２３】
前記押圧力付与機構３１は定置本体部４の左右の垂直支持壁部８、８の後端縁間に架設された左右向き部材３７の長さ中央箇所に断面溝形の押圧部材３９をヒンジ継手４０を介してその屈折軸４１回りの上下揺動自在に装着すると共にこの押圧部材３９をヒンジ継手４０回りの上方へ付勢するための図示しないバネ（コイルバネ、スプリングなど）を装着し、このバネの弾力で押圧部材３９の先部切欠凹み面ｈが前記門形棒部材３４の左右方向長さ中央箇所に下側から圧接されるものとなしてある。
【００２４】
前記制限機構３２は定置本体部４の前記左右向き部材３７の左右２箇所に２つの前記係合棒部材３５、３５の左右向き部を受け止め可能とした制限部材をなすボルト４２、４２を縦向きに螺着し、これらボルト４２、４２の上下位置を変更調製可能とした構成となされている。
【００２５】
上記した係止爪作動手段２９は次のように作動する。
Ｌ字型反転枠６が基準位置ｄ１にあるとき、押圧部材３９の先部段部ｈ１が図７に示すように門形棒部材３４に圧接するか或いは近接した状態となる。このとき、制限機構３２のボルト４２、４２は係合部材３５、３５の左右向き部に近接するか或いは圧接した状態となるのであり、この状態で仮に押圧部材３９の先部段部ｈ１が門形棒部材３４から外れるような事態が生じても、このときは係合部材３５、３５の左右向き部がボルト４２、４２に受け止められるため、係止爪棒部材２８は図７中の基準位置ｄ１に対応した状態とほぼ同じ状態に保持され、係止爪２８ａ、２８ａはＬ字型反転枠６の垂直支持面部１５の板部材１９の透孔ｊ、ｊから後側へ突出するものとならない。
【００２６】
駆動機構２１が作動すると、Ｌ字型反転枠６が基準位置ｄ１のとき下向き状態にあった出力アーム２５、２５が後向き上方へ回動され、結合棒部材２７、２７がＬ字型反転枠６を左右向き軸５回りの後向き上方へ揺動させる。この揺動中、Ｌ字型反転枠６上の位置で押圧部材３９の先部段部ｈ１に対応する点は図５に示すように左右向き軸５を曲がり中心とした第一円弧軌跡ｋ１を辿り、また押圧部材３９の先部段部ｈ１の位置は屈折軸４１を曲がり中心とした第二円弧軌跡ｋ２を辿るものとなり、また門形棒部材３４は図示しないバネの弾力で押圧部材３９の先部切欠凹み面ｈに常に圧接した状態に保持される。従って、Ｌ字型反転枠６の上方揺動が図７中の基準位置ｄ１から進行するに伴って、Ｌ字型反転枠６の揺動位置に対応した２点、即ち第一円弧軌跡ｋ１上の点と第二円弧軌跡ｋ２上の点とが離反するようになり、この離反に基づいて、係止爪棒部材２８の左右向き辺部２８ｂが先部段部ｈ１と門形棒部材３４との当接状態下で先部段部ｈ１から遠ざかるものとなり、これにより係止爪棒部材２８は引張スプリング３６の弾力で左右向き辺部２８ｂ回りの図７中右回りへ揺動するものとなるのであり、こうしてＬ字型反転枠６の上方揺動が特定揺動位置ｄ３に達したときには、係止爪２８ａ、２８ａはＬ字型反転枠６の板部材１９の透孔ｊ、ｊから完全に突出して、完全な出側に位置した状態となり、このとき左右向き辺部２８ｂ回りへのそれ以上の変位を板部材１９との当接により規制される。
【００２７】
この後、Ｌ字型反転枠６の上方揺動がさらに増大されると、もはや係止爪棒部材２８は左右向き辺部２８ｂ回りへ揺動しないまま先部段部ｈ１が第二円弧軌跡ｋ２上を移動して係止爪棒部材２８の左右向き辺部２８ｂからさらに大きく離反するため、押圧部材３９の先部段部ｈ１は門形棒部材３４から次第に大きく離れていくのであり、従ってＬ字型反転枠６の上方揺動の増大にも拘わらず、前記特定揺動位置ｄ３でのＬ字型反転枠６に対する係止爪棒部材２８の位置はそのまま維持される。
【００２８】
そして、最終的にはこのＬ字型反転枠６は図７に示す収容物取出位置ｄ２に到達するのであり、この時点で駆動機構２１の作動が一時停止されてＬ字型反転枠６の上方揺動は停止される。この停止状態では、各係合棒部材３５の左右向き部は駆動機構２１の結合棒部材２７の特定箇所と近接し或いは当接した状態となるのであり、この状態で、仮に、押圧部材３９の先部段部ｈ１が門形棒部材３４から外れるような事態が生じても、図７に示すように係合部材３５、３５の左右向き部が結合棒部材３７、３７に受け止められるため、係止爪棒部材２８は図７中の収容物取出位置ｄ２に対応した状態とほぼ同じ状態に保持され、係止爪２８ａ、２８ａはＬ字型反転枠６の板部材１９の透孔ｊ、ｊからその支持面ｆ上に完全に突出した状態を維持されるのである。
【００２９】
また図３〜図６に示すように、Ｌ字型反転枠６の水平支持部１４と、前記定置本体部４の垂直支持壁部８、８の後側に設けた後方張出枠部４３との間には、前記水平支持部１４に載せられた空の上面開放容器ａを前記Ｌ字型反転枠６の揺動変位過程の特定位置で左右方向へ落下させるものとした容器放出機構４４が設けてある。
【００３０】
この容器放出機構４４は、前記水平支持部６に載せられた上面開放容器ａを左右傾斜状に押し上げるための容器押上揺動部材４５と、前記容器押上揺動部材４５に特定大きさ以上の押上力を前記Ｌ字型反転枠６の揺動変位過程の一定範囲内でのみ付与するように作動する押上力付与機構４６とを備えたものとなされている。
【００３１】
前記容器押上揺動部材４５はＬ字型反転枠６の水平支持部１４の左右向きローラ１７間の前後に離れた２箇所に配置された一対の左右向き棒部材４７、４７と、これらの長さ途中を結合する結合部材４８からなり、前記左右向き棒部材４７、４７の左端は水平支持部１４の方形枠部材１６の左側前後向き部材１６ａの前後箇所に設けられた一対の軸受部材４８、４８で回動自在に支持された前後向き支点軸４９に固着されている。
【００３２】
前記押上力付与機構４６は、Ｌ字型反転枠６の水平支持部１４の方形枠部材１６の左右向き部材１６ｂの長さ中央箇所で左右向きローラ１７よりも下側箇所に前後向きの軸受管５０を固着すると共に、この軸受管５０に支点軸５１を回動自在に挿通させ、この支点軸５１の前端に入力アーム５２を固定すると共に後端に出力アーム５３を固定し、前記入力アーム５２の先端には左右向き支持軸５４回りへ回転自在となされたローラ５５を装着して、前記出力アーム５３の先端には前記容器押上揺動部材４５の前側の左右向き棒部材４７、４７を押し上げるものとなされ前後向き支持軸５６回りへ回転自在となされた溝付ローラ５７を装着するほか、図４などに示すように前記入力アーム５２と垂直支持面部１５の左右向き部材１８ｂとの間に引張スプリング５８を設け、一方では前記定置本体部４の垂直支持壁部８、８の後方張出枠部４３の左右向き部材４３ａの長さ中央箇所と、前記定置本体部４の垂直支持壁部８、８の後端縁間に架設された左右向き部材５９の長さ中央箇所との間に、前記ローラ５５を支持案内するための前後向き案内部材６０を設けた構成となされている。
【００３３】
この際、引張スプリング５８の弾力は入力アーム５２に何らの外力も作用しない状態では空の上面開放容器ａを載置された容器押上揺動部材４５を押し上げるべく出力アーム５３の先端を上方変位させるものとなるが、前記上面開放容器ａ内に一定量以上の収容物が存在するときはその重みで前記出力アーム５３が下方変位される大きさとなされている。
【００３４】
次に前記搬送物係止機構付ローラコンベア２ついて図１、図２及び図８を参照して説明する。
図８に示すように、複数の左右向きローラ６１を、左右の前後向き部材６２ａ、６２ｂと前後の左右向き部材６２ｃ、６２ｄからなる枠体６２に回転自在に軸着してローラコンベアを形成すると共に、前記枠体６２の内方で前記左右向きローラ６１の下側に方形枠部材６３を配設している。
【００３５】
この方形枠部材６３は左右各側の前後向き部材６３ａ、６３ｂの長さ中央箇所をこれら前後向き部材６３ａ、６３ｂに固定された左右向き軸６４ａ、６４ｂを介して前記枠体６２の左右の前後向き部材６３ａ、６３ｂに前記左右向き軸６４ａ、６４ｂ回りの揺動自在に支持され、前側の左右向き部材６３ｃに門形の第一搬送物係止部材６５ａを、そして後側の左右向き部材６３ｄに門形の第二搬送物係止部材６５ｂを起立状に固定されている。この際、第一搬送物係止部材６５ａと第二搬送物係止部材６５ｂの間は左右向きローラ６１で搬送される上面開放容器ａの搬送方向長さよりも大きくなされる。
【００３６】
また前記枠体６２の左側の前後向き部材６２ａの外側に導かれた前記左右向き軸６４ａの先端には前側へ延びた棒状の入力部材６６を固定すると共に、この入力部材６６の先端入力部６６ａを上方変位させる側へ付勢するための図示しないバネを装着している。
【００３７】
そして、この入力部材６５の先端入力部６５ａに何らの作動力も付与されないときは、方形枠部材６３の前側がバネ力で上方へ変位されて、第一搬送物係止部材６５ａの上部が図８Ａに示すように前後で隣接した左右向きローラ６１、６１間を通じて、各左右向きローラ６１の頂点を連ねたコンベア搬送支持面から突出した状態となり、一方、入力部材６６の先端入力部６６ａに適当大きさの下向き作動力が付与されたときは、方形枠部材６３の後側がバネ力で上方へ変位されて、第二搬送物係止部材６５ｂの上部が前後で隣接した左右向きローラ６１、６１間を通じて前記コンベア搬送支持面から突出した状態となる構成となされている。
【００３８】
さらに前記枠体６２の前端部は定置本体部４の後方張出枠部４３の後端部に載置状に嵌合されるのであり、この際、左右向きローラ６１で形成された前記コンベア搬送支持面が水平支持部１４の左右向きローラ１７の頂点を連ねた容器支持面に合致される。
【００３９】
前記水平ローラコンベア３は次のようなものとなされているのであって、即ち図１に示すように、方形枠体６７の内方の前後方向へ左右向きローラ６８を並列状且つ回転自在に軸着したものとなされている。このコンベア３の方形枠体６７の前端部には前記搬送物係止機構付ローラコンベア２の枠体６２の後端部が載置状に嵌合される。この際、左右向きローラ６８の頂点を連ねたコンベア搬送支持面が搬送物係止機構付ローラコンベア２のそれと合致されるようになされる。
【００４０】
次に上記した本発明装置の使用例と、その際の作動について説明する。
みかんなどの農作物を収容した上面開放容器ａであるバスケットが水平ローラコンベア３の近傍に運搬されるのであり、作業者はこれら収容物入りバスケットａの一つづつを順次に左右向きローラ６８からなるコンベア搬送支持面の適当位置ｍ１に載せる。
【００４１】
そして、Ｌ字型反転枠６が基準位置ｄ１から離れている状態において、搬送物係止機構付ローラコンベア２の第一及び第二搬送物係止部材６５ａ、６５ｂ間にバスケットａが存在しないことを確認して、水平ローラコンベア３上の収容物入りバスケットａを前方へ押し、これを搬送物係止機構付ローラコンベア２の第一及び第二搬送物係止部材６５ａ、６５ｂ間に移動させる。このように押し移動される収容物入りバスケットａは左右向きローラ６８、１７に案内されるため比較的小さな力で前進し、第一搬送物係止部材６５ａ存在位置に達したとき、その底部前端がその第一搬送物係止部材６５ａに係止され、その位置に停止する。
【００４２】
この後、Ｌ字型反転枠６が基準位置ｄ１に到達すると、入力部材６６がＬ字型反転枠６の水平支持部１４の四角枠部材１６下面に押され、第一搬送物係止部材６５ａは左右向きローラ１７によるコンベア搬送支持面から没作動し、第二搬送物係止部材６５ｂはそのコンベア搬送面から出作動した状態となる。この状態では、水平ローラコンベア３上の次の収容物入りバスケットａを前方へ押し移動させても、このバスケットａは底部前端を第二搬送物係止部材６５ｂに係止されて図１中の仮想線位置ｍ２に停止されるのであり、一方、先に第一搬送物係止部材６５ａに係止されていた収容物入りバスケットａは搬送物係止機構付ローラコンベア２が前下がりに配置されていることにより自重作用で前進し、Ｌ字型反転枠６の水平支持部１４上に達して垂直支持面部１５に近接し或いは当接した状態となる。
【００４３】
収容物入りバスケットａが水平支持部１４上に位置したことに関連して、自動的に或いは手動によるスイッチ操作により、駆動機構２１が正側へ作動して、水平支持部１４が左右向き軸５回りの後上方へ向け揺動駆動される。
【００４４】
この揺動駆動によってＬ字型反転枠６が特定揺動位置ｄ３に達したとき左右２つの係止爪２８ａ、２８ａが垂直支持面部１５の支持面ｆ上に完全に突出して、垂直支持面部１５に支持された状態の収容物入りバスケットａの前側面上縁の溝ａ１内に入り込むのであり、この後、Ｌ字型反転枠６が収容物取出位置ｄ２近傍位置に達すると、垂直支持面部１５は上部が下部よりも低くなるように前後傾斜される。この傾斜によりＬ字型反転枠６上の収容物入りバスケットａも図９に示すように前後傾斜されるのであり、この際、収容物入りバスケットａは係止爪２８ａ、２８ａの係止作用により垂直支持面部１５上を前側へ滑り落ちるのを確実に規制される。そして、この前後傾斜が一定角度以上になると、収容物入りバスケットａ内の収容物のみが前方へ転がり落ち、案内板部材９や案内板延長部９ａ上を経て収容物受入部１０内に達する。
【００４５】
Ｌ字型反転枠６が収容物取出位置ｄ２に達して適当時間が経過したとき、駆動機構２１はこれまでとは逆に作動され、これにより、Ｌ字型反転枠６は基準位置ｄ１へ向けて下方揺動されるのであり、この下方揺動中において係止爪２８ａ、２８ａが垂直支持面部１５の支持面ｆに対し一定量以上に没側へ変位した状態となるまでは、水平支持部１４上のバスケットａは係止爪２８ａ、２８ａで水平支持部１４の水平支持面に直交した方向の変位を規制され且つ容器押上揺動部材４５及び引張スプリング５８により底面に押上げ力を付与されるため、係止爪２８ａ、２８ａと容器押上揺動部材４５とに挟圧されて水平支持部１４上での位置を安定的に保持される。そしてＬ字型反転枠６が特定揺動位置ｄ３を越えて基準位置ｄ１に近づくと、係止爪２８ａ、２８ａは垂直支持面部１５の支持面ｆから完全に没し没側に位置した状態となる。こうして係止爪２８ａ、２８ａがバスケットａから離れると直ちに係止爪２８ａ、２８ａによるバスケットａの変位規制作用が消失するため、図１０に示すように容器押上揺動部材４５がこれの上方に位置した空状態のバスケットａを支持したまま、引張スプリング５８の弾力により前後向き支点軸４９回りの上方へ揺動されて大きく左下がりに傾斜される。これにより空バスケットａは重力作用により容器押上揺動部材４５上を左側へ滑り落ち、Ｌ字型反転枠６上から地上に降ろされるものとなる。
【００４６】
この後、Ｌ字型反転枠６がさらに基準位置ｄ１に近接すると、入力アーム５２先端のローラ５５が前後向き案内部材６０の上面に当接し、Ｌ字型反転枠６の下方揺動の進行に伴ってその案内部材６０に押し上げられるのであり、これにより容器押上揺動部材４５は引張スプリング５８の弾力に抗してその左右傾斜が減少する側へ向けて変位する。そしてＬ字型反転枠６が基準位置ｄ１に達したとき、容器押上揺動部材４５は水平状となって左右向きローラ１７による容器支持面よりも下方に位置する。
【００４７】
上記のように基準位置ｄ１に達したＬ字型反転枠６は再び入力部材６６の先端入力部６６ａを押し下げるのであり、これにより、既述と同様にして搬送物係止機構付ローラコンベア２上にて第一搬送物係止部材６５ａに係止された状態となされた次の収容物入りバスケットａが先と同様に水平支持部６上に移動する。以後は同様な作動の繰り返しである。
この繰返し作動により定置本体部４の収容物受入部１０内には収容物が滞留するものとなるが、このように滞留した収容物は連続駆動されるバケットコンベア１１により前方の搬出口ｃから外方へ搬出され、予め用意された出荷用容器ｎ内に落下する。
【００４８】
上記実施例では搬送物係止機構付ローラコンベア２や水平ローラコンベア３を使用したが、これらを省略することも差し支えないであり、この場合は作業者が手作業により、Ｌ字型反転枠６の水平支持部１４上に収容物入りバスケットａを載せるようにする。
【００４９】
【発明の効果】
上記した本発明によれば次のような効果が得られるのである。
即ち、収容物が取り出された後の上面開放容器を水平支持部１４から地上などに降ろす処理を重力作用による滑り移動で人為力を要することなく行わせることができると共に上面開放容器ａ内からその収容物を的確に取り出すことができるものとなり、また基準位置ｄ１にあるＬ字型反転枠６に手作業などで上面開放容器を載せることは任意になし得ることであるが、この場合、収容物が取り出された直後の上面開放容器が降下された後、次の上面開放容器をＬ字型反転枠６に載せるときなどに係止爪２８ａ、２８ａが障害を及ぼすことのないものとなり、また係止爪２８ａ、２８ａが他物との接触で損壊したり作業者を負傷させることのないものとなる。特に請求項１記載の発明では、係止爪２８ａ、２８ａがＬ字型反転枠６の左右向き軸５回りの位置に連動してスプリング３６の弾力に対応した力で必要時に出作動され不必要時に定置本体部４に結合された押圧部材３９に押されて没作動されるため、係止爪２８ａ、２８ａは的確に出没作動するものとなり、上面開放容器ａ内からその収容物を一層的確に取り出すことができるものとなる。
【００５０】
さらにはＬ字型反転枠６が基準位置に到達する前にＬ字型反転枠６上の空の上面開放容器が地上などに簡易な機構により迅速に降下されるようになり、Ｌ字型反転枠６が基準位置ｄ１に到達したとき係止爪２８ａ、２８ａが障害を及ぼすことなく次の上面開放容器を直ちに水平支持部１４に載置することのできるものとなる。

The locking claw mechanism 30 fixes U-shaped bearing plate members 33, 33 in a front view to the left and right side portions of the left and right facing member 18b of the vertical support surface portion 15, and from the left and right end portions of the left and right facing side portion 28b. The longitudinal side portions 28c, 28c are extended and the front end of each longitudinal side portion 28c is bent forward to form a locking claw bar member 28 whose front side becomes a locking claw 28a from the bent portion, The left and right side portions 28b are rotatably inserted into the shaft holes g of the pair of bearing plate members 33 and 33, and a gate shape is formed at a relatively middle portion between the left and right vertical side portions 28c and 28c. The bar member 34 is fixed in an erected shape, and a 90-degree bent engagement bar member 35 is fixed to a substantially central portion of each vertical side portion 28c. A tension spring 36 is installed between the corresponding bearing plate member 33. It is without a configuration.
[0023]
The pressing force applying mechanism 31 includes a pressing member 39 having a groove-shaped cross section at a central position in the length direction of a laterally facing member 37 installed between the rear end edges of the left and right vertical supporting wall portions 8 and 8 of the stationary main body portion 4. A spring (not shown) (coil spring, spring, etc.) for urging the pressing member 39 upward around the hinge joint 40 is mounted via the pin 40 so that it can swing up and down around the refraction axis 41. The front notch recessed surface h of the pressing member 39 is pressed against the central portion of the length of the portal bar member 34 in the left-right direction by the elasticity of
[0024]
The restricting mechanism 32 has the bolts 42 and 42 constituting the restricting members that can receive the left and right facing portions of the two engaging rod members 35 and 35 at two left and right positions of the left and right facing member 37 of the stationary main body portion 4 in the vertical direction. The bolts 42 and 42 can be adjusted by changing the vertical positions of the bolts 42 and 42.
[0025]
The above-described locking claw operating means 29 operates as follows.
When the L-shaped reversal frame 6 is at the reference position d1, the tip step portion h1 of the pressing member 39 is in pressure contact with or close to the gate-shaped bar member 34 as shown in FIG. At this time, the bolts 42 and 42 of the limiting mechanism 32 are in a state of being close to or in pressure contact with the left and right direction portions of the engaging members 35 and 35. In this state, the front stepped portion h1 of the pressing member 39 is temporarily connected to the gate. Even if a situation occurs in which the rod member 34 comes off, the left and right portions of the engaging members 35 and 35 are received by the bolts 42 and 42 at this time, so that the locking claw rod member 28 is at the reference position in FIG. The locking claws 28a, 28a are held in substantially the same state as that corresponding to d1, and the locking claws 28a, 28a do not protrude rearward from the through holes j, j of the plate member 19 of the vertical support surface portion 15 of the L-shaped reversal frame 6. .
[0026]
When the drive mechanism 21 is actuated, the output arms 25 and 25 that were in the downward state when the L-shaped reversal frame 6 is at the reference position d1 are rotated rearward and upward, and the connecting rod members 27 and 27 are moved to the L-shaped reversal frame 6. Is swung backward and upward about the left-right axis 5. During this swinging, the point corresponding to the tip step h1 of the pressing member 39 at the position on the L-shaped reversal frame 6 is the first arc locus k1 with the left-right axis 5 as the center of bending as shown in FIG. Further, the position of the tip step h1 of the pressing member 39 follows the second arc locus k2 with the refraction axis 41 as the center of bending, and the gate-shaped rod member 34 has the elasticity of the pressing member 39 by the elasticity of a spring (not shown).Front notch recessed surface hIs always kept in pressure contact. Therefore, as the upward swing of the L-shaped reversal frame 6 proceeds from the reference position d1 in FIG.Two points corresponding to the swinging position of the L-shaped reversal frame 6, that is, a point on the first arc locus k 1 and a point on the second arc locus k 2 are separated from each other. The laterally facing side portion 28b of the claw bar member 28 moves away from the front end step portion h1 under the contact state between the front end step portion h1 and the gate-shaped bar member 34.The locking claw bar member 28 isWith the elasticity of the tension spring 36Swing clockwise in FIG. 7 around the side part 28b facing left and rightBecause it will be,Thus, the upward swing of the L-shaped reversal frame 6 isWhen the specific swing position d3 is reached, the locking claws 28a, 28a completely protrude from the through holes j, j of the plate member 19 of the L-shaped reversal frame 6.The,It will be in a state of being completely on the exit side,At this time, further displacement around the side part 28 b facing right and left is restricted by contact with the plate member 19.
[0027]
Thereafter, when the upward swing of the L-shaped reversal frame 6 is further increased, the locking claw bar member 28 no longer swings around the left and right side portions 28b.The leading edge step h1 moves on the second circular arc locus k2 and is further separated from the left and right side portion 28b of the locking claw bar member 28.Therefore, the front end step portion h1 of the pressing member 39 is gradually separated from the gate-shaped bar member 34, and therefore the specific swing position d3 is increased despite the increase in upward swing of the L-shaped reversal frame 6. The position of the locking claw bar member 28 with respect to the L-shaped reversal frame 6 is maintained as it is.
[0028]
Finally, the L-shaped reversal frame 6 reaches the accommodation take-out position d2 shown in FIG. 7, and at this time, the operation of the drive mechanism 21 is temporarily stopped and the L-shaped reversal frame 6 is positioned above the L-shaped reversal frame 6. Oscillation is stopped. In this stopped state, the left and right facing portions of the respective engagement rod members 35 are in close proximity to or in contact with specific portions of the coupling rod member 27 of the drive mechanism 21. Even if a situation occurs in which the leading step h1 is detached from the gate-shaped rod member 34, the left and right portions of the engaging members 35, 35 are received by the coupling rod members 37, 37 as shown in FIG. The pawl bar member 28 is held in substantially the same state as the state corresponding to the stored item take-out position d2 in FIG. 7, and the locking claws 28a, 28a are the through holes j, j of the plate member 19 of the L-shaped reversal frame 6. Thus, a state of completely projecting on the support surface f is maintained.
[0029]
As shown in FIGS. 3 to 6, the horizontal support portion 14 of the L-shaped reversal frame 6 and the rear extending frame portion 43 provided on the rear side of the vertical support wall portions 8 and 8 of the stationary main body portion 4. In the meantime, there is a container discharge mechanism 44 that causes the empty upper open container a placed on the horizontal support portion 14 to drop in the left-right direction at a specific position in the swinging displacement process of the L-shaped reversal frame 6. It is provided.
[0030]
The container discharge mechanism 44 includes a container push-up rocking member 45 for pushing up the upper open container a placed on the horizontal support 6 in a left-right inclined manner, and the container push-up rocking member 45 pushes up a specific size or more. A push-up force applying mechanism 46 that operates so as to apply force only within a certain range of the swing displacement process of the L-shaped reversal frame 6 is provided.
[0031]
The container push-up swing member 45 includes a pair of left and right bar members 47, 47 disposed at two positions separated from each other between the left and right rollers 17 of the horizontal support portion 14 of the L-shaped reversal frame 6, and their lengths. A pair of bearing members 48 provided at the front and rear positions of the left and right front and rear facing members 16a of the rectangular frame member 16 of the horizontal support portion 14, 48 is fixed to a fulcrum shaft 49 facing forward and backward, which is supported rotatably.
[0032]
The push-up force imparting mechanism 46 is a bearing tube facing in the front-rear direction at a position below the left-right roller 17 at a central position of the left-right direction member 16 b of the rectangular frame member 16 of the horizontal support portion 14 of the L-shaped reversal frame 6. 50, and a fulcrum shaft 51 is rotatably inserted into the bearing tube 50.in frontWhile fixing the input arm 52 to the endrearAn output arm 53 is fixed to the end, and a roller 55 that is rotatable about a left-right support shaft 54 is attached to the tip of the input arm 52, and the container push-up swing member is attached to the tip of the output arm 53. In addition to mounting a grooved roller 57 that pushes up the front left and right bar members 47, 47 on the front side of 45 and is rotatable around the support shaft 56 in the front-rear direction, as shown in FIG. A tension spring 58 is provided between the left and right facing members 18b of the support surface portion 15 and, on the other hand, a central portion of the length of the left and right facing members 43a of the rearward extending frame portions 43 of the vertical support wall portions 8 and 8 of the stationary main body portion 4. And a longitudinal guide for supporting and guiding the roller 55 between the vertical support wall portions 8 and 8 of the stationary main body 4 and a central portion of the length of the left and right orientation member 59 provided between the rear end edges. Set member 60 It has been made and configurations.
[0033]
At this time, the elastic force of the tension spring 58 causes the tip of the output arm 53 to be displaced upward to push up the container push-up swinging member 45 on which the empty upper open container a is placed in a state where no external force acts on the input arm 52. However, when there is a certain amount or more of items in the upper open container a, the weight of the output arm 53 is displaced downward.
[0034]
Next, the roller conveyor 2 with the conveyed product locking mechanism will be described with reference to FIGS.
As shown in FIG. 8, a plurality of left and right rollers 61 are rotatably mounted on a frame 62 composed of left and right front and rear members 62a and 62b and front and rear left and right members 62c and 62d to form a roller conveyor. In addition, a rectangular frame member 63 is disposed on the inner side of the frame body 62 and below the left-right roller 61.
[0035]
This rectangular frame member 63 has front and rear left and right front and rear sides of the frame body 62 via left and right shafts 64a and 64b fixed to the front and rear facing members 63a and 63b. The direction members 63a and 63b are supported so as to be swingable about the left and right direction shafts 64a and 64b, the front left and right direction member 63c is provided with a gate-shaped first transporting object locking member 65a, and the rear side and right and left direction member 63d. A gate-shaped second conveyed product locking member 65b is fixed upright. At this time, the distance between the first transported object locking member 65a and the second transported object locking member 65b is made larger than the length in the transport direction of the upper open container a transported by the left-right roller 61.
[0036]
Further, a rod-like input member 66 extending to the front side is fixed to the front end of the left-right direction shaft 64a guided to the outside of the front-rear facing member 62a on the left side of the frame body 62, and a front end input portion 66a of the input member 66 is fixed. A spring (not shown) for urging the lens toward the side to be displaced upward is attached.
[0037]
When no operating force is applied to the distal end input portion 65a of the input member 65, the front side of the rectangular frame member 63 is displaced upward by a spring force, and the upper portion of the first transported object locking member 65a is shown in FIG. 8A. As shown in FIG. 5, the front and rear rollers 61 are adjacent to each other and protrude from the conveyor conveyance support surface where the apexes of the left and right rollers 61 are connected, while the front end input portion 66a of the input member 66 has an appropriate size. When the downward operating force is applied, the rear side of the rectangular frame member 63 is displaced upward by the spring force, and the upper part of the second conveyed product locking member 65b is located between the left and right rollers 61, 61 adjacent in the front and rear direction. It is set as the structure which protrudes from the said conveyor conveyance support surface through.
[0038]
Further, the front end portion of the frame body 62 is fitted to the rear end portion of the rear projecting frame portion 43 of the stationary main body portion 4 so as to be placed. At this time, the conveyor transport formed by the left and right rollers 61 is used. The support surface is matched with the container support surface connecting the apexes of the left and right rollers 17 of the horizontal support portion 14.
[0039]
The horizontal roller conveyor 3 has the following structure, that is, as shown in FIG. 1, the left and right rollers 68 are arranged in a parallel and rotatable manner in the longitudinal direction inside the rectangular frame 67. It is supposed to be worn. The rear end portion of the frame body 62 of the roller conveyor 2 with the conveyed product locking mechanism is fitted in the front end portion of the rectangular frame body 67 of the conveyor 3 in a mounting manner. At this time, the conveyor conveyance support surface in which the apexes of the left and right rollers 68 are connected to the roller conveyor 2 with the conveyed product locking mechanism.
[0040]
Next, a usage example of the above-described apparatus of the present invention and an operation at that time will be described.
A basket, which is an open top container a containing crops such as mandarin oranges, is transported to the vicinity of the horizontal roller conveyor 3. Place it at an appropriate position m1 on the transport support surface.
[0041]
And, in a state where the L-shaped reversal frame 6 is away from the reference position d1, there is no basket a between the first and second conveyed object locking members 65a and 65b of the roller conveyor 2 with the conveyed object locking mechanism. After confirming the above, the stored basket a on the horizontal roller conveyor 3 is pushed forward, and this is moved between the first and second conveyed object locking members 65a and 65b of the roller conveyor 2 with a conveyed object locking mechanism. Since the basket a containing the object to be pushed and moved in this way is guided by the left and right rollers 68 and 17, it moves forward with a relatively small force, and when the first conveyance object locking member 65 a reaches the position, the bottom front end of the container a It is locked by the first transported object locking member 65a and stops at that position.
[0042]
Thereafter, when the L-shaped reversal frame 6 reaches the reference position d1, the input member 66 is pushed against the lower surface of the square frame member 16 of the horizontal support portion 14 of the L-shaped reversal frame 6, and the first transported object locking member 65a. Is submerged from the conveyor conveyance support surface by the left-right roller 17, and the second conveyed product locking member 65b is activated from the conveyor conveyance surface. In this state, even if the next basket a containing contents on the horizontal roller conveyor 3 is pushed and moved forward, the basket a is locked at the front end of the bottom by the second transported object locking member 65b, and the virtual in FIG. On the other hand, in the basket a containing things previously locked to the first transported object locking member 65a, the roller conveyor 2 with a transported object locking mechanism is disposed in the front downward direction. As a result, the vehicle moves forward by its own weight, reaches the horizontal support portion 14 of the L-shaped reversal frame 6, and comes close to or in contact with the vertical support surface portion 15.
[0043]
In association with the container a containing the container a positioned on the horizontal support portion 14, the drive mechanism 21 is operated to the positive side automatically or by a manual switch operation, and the horizontal support portion 14 rotates about the horizontal axis 5. It is driven to swing upward and rearward.
[0044]
When the L-shaped reversal frame 6 reaches the specific swing position d3 by this swinging drive, the two left and right engaging claws 28a, 28a completely project on the support surface f of the vertical support surface portion 15, and the vertical support surface portion 15 Is inserted into the groove a1 on the upper edge of the front side surface of the basket a containing the object in a supported state. After that, when the L-shaped reversal frame 6 reaches a position near the container take-out position d2, the vertical support surface portion 15 is It is inclined forward and backward so that the upper part is lower than the lower part. As shown in FIG. 9, the basket a containing the material on the L-shaped reversal frame 6 is also tilted back and forth by this inclination. At this time, the basket a containing material is vertically supported by the locking action of the locking claws 28a and 28a. Sliding down on the front surface 15 is reliably regulated. When the forward / backward inclination becomes equal to or greater than a certain angle, only the stored items in the stored basket a fall down and reach the stored item receiving unit 10 via the guide plate member 9 and the guide plate extension 9a.
[0045]
When the L-shaped reversal frame 6 reaches the contents take-out position d2 and an appropriate time has elapsed, the drive mechanism 21 is operated in the reverse direction, and the L-shaped reversal frame 6 moves toward the reference position d1. Is swung downwardDuring this downward swing, the baskets a on the horizontal support portion 14 are kept until the locking claws 28a, 28a are displaced to the sunk side by a predetermined amount or more with respect to the support surface f of the vertical support surface portion 15. Since the displacement in the direction perpendicular to the horizontal support surface of the horizontal support portion 14 is restricted by the locking claws 28a, 28a and the pushing force is applied to the bottom surface by the container push-up swing member 45 and the tension spring 58, the locking claws 28a, 28a and the container push-up swing member 45, and the position on the horizontal support portion 14 is stably held.. When the L-shaped reversal frame 6 approaches the reference position d1 beyond the specific swing position d3, the locking claws 28a and 28a are completely submerged from the support surface f of the vertical support surface portion 15.Located on the vacant sideIt becomes a state.ThusLocking claws 28a, 28a are basketsaAs soon as you leaveBecause the displacement restricting action of the basket a by the locking claws 28a, 28a disappears.As shown in FIG. 10, the container push-up swing member 45 is swung upwards around the fulcrum shaft 49 in the front-rear direction by the elastic force of the tension spring 58 while supporting the empty basket a positioned above it. Inclined to the left. As a result, the empty basket a slides down to the left on the container push-up swing member 45 by the gravitational action, and is lowered from the L-shaped reversal frame 6 to the ground.
[0046]
Thereafter, when the L-shaped reversal frame 6 further approaches the reference position d1, the roller 55 at the front end of the input arm 52 comes into contact with the upper surface of the front-rear direction guide member 60, and the L-shaped reversal frame 6 moves downward. Along with this, the guide member 60 is pushed up, whereby the container push-up swinging member 45 is displaced toward the side where the lateral inclination is reduced against the elasticity of the tension spring 58. AndL-shaped reversal frameWhen 6 reaches the reference position d1,The container push-up swing member 45 isIt becomes horizontal and is positioned below the container support surface by the left-right roller 17.
[0047]
As described above, the L-shaped reversal frame 6 that has reached the reference position d1 pushes down the tip input portion 66a of the input member 66 again. Then, the next basket a containing contents that has been locked to the first transported object locking member 65a moves onto the horizontal support portion 6 in the same manner as described above. Thereafter, the same operation is repeated.
This repetitive operation causes the stored material to stay in the stored material receiving portion 10 of the stationary main body 4. The stored material is removed from the front carry-out port c by the bucket conveyor 11 that is continuously driven. And is dropped into a shipping container n prepared in advance.
[0048]
In the above embodiment, the roller conveyor 2 with the conveyed product locking mechanism and the horizontal roller conveyor 3 are used. However, these may be omitted. In this case, the operator manually performs the L-shaped reversal frame 6. The basket a containing contents is placed on the horizontal support portion 14.
[0049]
【The invention's effect】
According to the present invention described above, the following effects can be obtained.
That is, a process of lowering the upper open container after the contents are taken out from the horizontal support portion 14 to the ground or the like.Without the need for manpower by sliding due to gravityCan be doneIt will be possible to accurately take out the contents from inside the upper open container a,Further, it is possible to arbitrarily place the open top container on the L-shaped reversal frame 6 at the reference position d1 by manual work, in this case,After the top open container immediately after the contents are removed, the nextWhen placing an open container on the L-shaped reversal frame 6The locking claws 28a, 28aThere will be no obstacles, and the locking claws 28a, 28a will not be damaged by contact with other objects or injured the operator.In particular, in the first aspect of the present invention, the locking claws 28a, 28a are actuated when necessary by a force corresponding to the elasticity of the spring 36 in conjunction with the position of the L-shaped reversal frame 6 around the left-right axis 5 and unnecessary. Since it is pushed and depressed by the pressing member 39 coupled to the stationary main body 4 at times, the locking claws 28a and 28a accurately move in and out, so that the contents can be more accurately removed from the upper surface open container a. It can be taken out.
[0050]
Furthermore, the L-shaped reversal frame 6Before reaching the reference positionOn L-shaped reversal frame 6Empty top open containerButAbove the groundSuchWith a simple mechanismWhen the L-shaped reversal frame 6 reaches the reference position d1, the next claw 28a, 28a immediately puts the next open top container on the horizontal support portion 14 without causing an obstacle. It will be possible.
