【発明の属する技術分野】
この発明は、例えばミカンやリンゴ、トマト、柿、梨、桃、胡瓜、茄子、人参、芋、ネギなどの農作物（果菜物を含む）、魚介類、球技用ボール、食品、部品等の被収容物を容器に収容する作業及び被収容物が収容された容器を運搬する作業に用いられる容器運搬台車に関する。
【０００２】
【従来の技術】
従来、上述の容器運搬台車としては、例えば運搬用容器の底部を、台車本体の上面に設けた凹部に嵌合して、異なるサイズ及び同一サイズの運搬用容器を多数積載して運搬する特許文献１の容器運搬台車がある。
【０００３】
【特許文献１】
特開平８−１３３０９０号公報。
【０００４】
【発明が解決しようとする課題】
しかし、上述の運搬用容器を上下に積重ねて容器運搬台車により運搬する場合、運搬用容器の運搬数が多くなるほど、積重ね段数が高くなるため、例えば農作物が収容された重い容器を高所及び高位に持上げるのに労力が必要である。且つ、上段側に積重ねられた容器を分離及び農作物が収容された容器を上段側に積重ねるとき、例えば背伸びしたり、支持台を使用しなければならない。また、下段側の運搬用容器を分離及び積重ねるとき、例えば姿勢を低くするか、腰を屈めなければならず、作業姿勢が悪くなるため、作業者に与える負担が大きいという問題点を有している。
【０００５】
且つ、容器運搬台車から積み下ろされた容器を、農作物を収容する収容場所まで作業者の手で運搬するか、農作物が収容された重い容器を、容器運搬台車が置かれた場所まで作業者の手で運搬しなければならず、農作物を収容する作業と、農作物が収容された容器を運搬する作業とに手間及び時間が掛かるという問題点も有している。
【０００６】
この発明は上記問題に鑑み、複数の容器を上下に積重ねたまま運搬して、該容器を略水平状態に保持したまま容器持上げ手段で上方に持上げて積重ねることにより、被収容物を容器に収容する作業及び被収容物が収容された容器を運搬する作業が簡単且つ容易に行え、労力の軽減、作業性の向上及び能率アップを図ることができる容器運搬台車の提供を目的とする。
【０００７】
【課題を解決するための手段】
この発明は、被収容物が収容される容器を上下に積重ねて運搬する容器運搬台車であって、上記容器を略水平状態に保持したまま上方に持上げる容器持上げ手段と、上記容器持上げ手段により持上げられた容器を略水平状態に保持して、該持上げられる容器と、先に持上げられた容器とを上下に積重ねられた状態に保持する容器保持手段とを、走行機能を有する台車本体に備えた容器運搬台車であることを特徴とする。
【０００８】
上述の被収容物を、例えばミカンやリンゴ、トマト、柿、梨、桃、胡瓜、茄子、人参、芋、ネギなどの農作物（果菜物を含む）、魚介類、球技用ボール、食品、部品等で構成することができる。また、容器を、例えばプラスチックや金属、木、厚紙（段ボール紙）等の材質からなるコンテナやケースで構成することができる。
【０００９】
また、容器運搬台車を、例えば車輪やタイヤ、キャスター、クローラ（キャタピラー）等の輪体を台車本体の前後底部に取付けて４輪車又は３輪車に構成することができる。また、作業者の手押し力及び牽引力で走行移動する手動式の容器運搬台車を、例えば台車本体に搭載された蓄電池（バッテリー）や発電機（ジェネレータ）、外部電源から供給される電力で駆動する電動機（モータ）、或いは、ガソリンや軽油を燃料とする原動機（エンジン）等の駆動力で走行移動することもできる。且つ、例えばレバーやボタン、有線式又は無線式のコントローラ、パーソナルコンピュータ等の制御手段で走行を制御することも含まれる。
【００１０】
また、容器持上げ手段を、例えば容器持上げ機構を構成する足踏みペダルの足踏み操作により、容器が上方（略鉛直）に持上げられる方向に上下動及び昇降する容器持上げ台で構成することができる。また、容器保持手段を、例えば容器持上げ台により持上げられた容器の両側縁部及び前後底部に係止され、その容器を略水平状態に支持する一対の保持板で構成することができる。且つ、容器持上げ台及び一対の保持板を、例えば流体圧シリンダやソレノイド、ネジ軸、チェーン、スプロケット、ギャ、ラック、カム、モータ等の単一要素及び複数要素を組み合わせた機構で上下移動及び上下回動、前後移動する構成も含まれる。且つ、例えばローラーやコンベア等の搬送手段を容器持上げ台に設けてもよい。
【００１１】
つまり、複数の容器を上下に積重ねたまま容器運搬用台車に積載して、被収容物（例えば農作物）を容器に収容する収容場所に走行移動した後、容器運搬用台車に積載された容器群を上段側から分離し、被収容物を容器に複数収容する。収容済みの容器を、容器持上げ手段により略水平状態に保持して上方に持上げると共に、容器保持手段により略水平状態に保持する。続いて、被収容物が収容された残りの容器を順に持上げ、先に持上げられた容器に対して下方から嵌合及び合致して、上下方向に対して複数段積重ねる。この後、容器運搬台車を、上下に積重ねられた容器を分離する分離場所に走行移動して、容器積載部に積載された容器を上段側又は下段側から所定数ずつ分離し、被収容物が収容された容器を、例えば運搬車両やフォークリフトで運搬する等して、例えば選別場や出荷場等の取扱い場所に供給する。また、容器運搬台車全体を、上述の取扱い場所に運搬することもできる。
【００１２】
且つ、左右及び前後に積重ねられた複数群の容器を上段側から分離し、被収容物が収容された複数の容器を、左右及び前後に配列したまま上方に持上げて積重ねる構成も含まれる。
【００１３】
実施の形態として、上記被収容物が収容される容器を一旦載置する容器受け台を、上記容器持上げ手段よりも手前側で、上記容器保持手段よりも下方に設けることができる。また、上記容器持上げ手段を、上記容器を並列状態に保持して上方に持上げ可能に設け、上記容器保持手段を、上記容器持上げ手段により持上げられた容器を並列状態（例えば左右及び前後）に整列したまま上下に積重ねた状態に保持可能に設けることができる。また、上記容器運搬台車を、作業者の手押し力及び牽引力により走行移動可能に設けることができる。また、上記容器を、複数の被収容物が並列状態に整列して収容される構造及び上下に積重ね可能な構造に設けることができる。
【００１４】
【作用及び効果】
この発明によれば、容器運搬台車に積載された容器群を上段側から分離し、複数の被収容物を容器に収容した後、被収容物が収容された容器を容器持上げ手段により上方に持上げて複数段積重ねるので、被収容物が収容された重い容器を作業者の手で高所及び高位に持上げる必要がなく、容器を上下に積重ねる作業が簡単且つ容易に行えると共に、作業者に対する負担を少なくし、労力の軽減及び作業性の向上を図ることができる。
【００１５】
且つ、複数の容器を上下に積重ねたまま容器運搬用台車により運搬するので、容器を、被収容物を収容する場所まで作業者の手で運搬するか、被収容物が収容された重い容器を、容器運搬台車が置かれた場所まで作業者の手で運搬するような手間及び作業が省けると共に、容器を運搬する回数が少なくなり、被収容物を収容する作業及び被収容物が収容された容器を運搬する作業の能率アップを図ることができる。
【００１６】
【実施例】
この発明の一実施例を以下図面に基づいて詳述する。
【００１７】
図面は、被収容物の一例である農作物を、コンテナ型の容器に整列して収容する作業及び農作物が収容された容器を上下に積重ねて運搬する作業に用いられる容器運搬台車を示し、図１及び図２に於いて、この容器運搬台車１は、平面から見て略矩形を有する容器Ｂ…が積載される台車本体２を、例えば６個分の容器Ｂ…が上下（略鉛直）に積載される大きさ及び形状に形成し、左右一対の車輪３…を、台車本体２の前側底部及び後側底部に取付けて４輪車に構成している。つまり、作業者Ｃの手押し力及び牽引力により所望する方向（例えば前後方向及び左右方向）に対して走行移動する。
【００１８】
また、容器Ｂの積載数を、例えば６個以下及び６個以上に変更するか、一つの車輪３を、台車本体２の前側中央部又は後側中央部に取付けて３輪車に変更してもよい。且つ、車輪３の代わりに、例えば所望する向き及び方向に自由回転（略３６０度）するキャスターを取付けるか、タイヤやクローラ（キャタピラ）を取付けるか、その複数を組み合わせる等してもよい。
【００１９】
且つ、所定数の農作物Ａ…が収容された容器Ｂを上方（略鉛直）に持上げ、所定数の容器Ｂ…を下方及び下段側から１段ずつ順に積重ねる容器持上げ機構４を、台車本体２の下部中央に設け、所定数（実施例では６個）の容器Ｂ…が上下（略鉛直）に積重ねられた状態に保持する容器積載部５を、台車本体２の上部中央に設けている。
【００２０】
且つ、農作物Ａ…が収容されるまえの容器Ｂ及び農作物Ａ…が収容された容器Ｂを一旦載置する容器受け台６を、後述する一対の保持板１２よりも下方で、後述する降下位置に待機させた容器持上げ台７に対して略水平となる高さに水平架設すると共に、台車本体２及び容器持上げ台７の手前側（作業者Ｃ側）に架設している。
【００２１】
上述の容器持上げ機構４は、容器Ｂが載置される大きさ及び形状に形成した容器持上げ台７を、台車本体２の下部中央に配設したリンク機構８により上下動自在及び昇降自在に支持すると共に、容器持上げ台７の前後底部に配設したリンク機構８を構成するリンク８ａ，８ｂの略中間部を左右回動可能に連結し、リンク８ａの上端側を、容器持上げ台７の左側底面部に連結し、リンク８ａの下端側を、台車本体２の右側枠部２ａに対して左右移動可能に係合している。
【００２２】
且つ、リンク８ｂの下端側を、台車本体２の左側枠部２ａに連結し、リンク８ｂの上端側を、容器持上げ台７の右側底面部に対して左右移動可能に係合して、容器持上げ台７を、前後一対のリンク８ａ，８ｂにより略水平状態に支持すると共に、略筒状のコロ８ｄを、リンク８ｂ，８ｂの略中間部に垂設したアーム８ｃ下端部に対してリンク動作と略一致する方向に対して回転可能に取付けている。
【００２３】
且つ、上述のリンク機構８をリンク動作するための足踏みペダル９を、台車本体２の手前側下部（作業者Ｃ側下部）に軸架した支軸１０により上下回動可能に軸支すると共に、上述のコロ８ｄに対して当接される略筒状のコロ９ａを、足踏みペダル９の遊端部に対して上述のコロ８ｄと略直交する方向に回転可能に取付けている。
【００２４】
つまり、図２及び図５に示すように、作業者Ｃの足で足踏みペダル９の足踏み側を下方に向けて足踏み操作し、支軸１０を中心として、足踏みペダル９を上下回動すると共に、リンク機構８のアーム８ｃに取付けられたコロ８ｄを、足踏みペダル９の遊端側に取付けられたコロ９ａにより押上げ、リンク機構８を構成する前後一対のリンク８ｂ，８ｂを、図２中仮想線で示す降下状態及び図２中実線で示す上昇状態に往復リンク動作させ、容器Ｂが載置された容器持上げ台７を略水平状態に支持したまま上下方向（略鉛直方向）に移動させ、上述の容器受け台６に対して略水平となる降下位置と、後述する一対の保持板１２よりも上方に持上げられる上昇位置とに上下動及び昇降する。
【００２５】
前述の容器積載部４は、容器Ｂの前後底部に対して係止される一対の保持板１２を、台車本体２の前後部に立設した枠部２ｂ上端に対して相対向して取付け、容器持上げ台７の前後部に突出する容器Ｂの前後底部に係止される閉角度（略水平角度）と、容器Ｂの持上げが許容される開角度とに上下回動可能に設けている。
【００２６】
且つ、保持板１２は、外端側に近い部分を中心として上下回動可能に軸支しているので、外端側よりも内端側の方が重く、その内端側の自重により閉角度に回動復帰される。また、枠部２ｂ上端に取付けられたストッパー１３を、閉角度に回動復帰される保持板１２の外端側上面部に当接して、容器Ｂが略水平状態に支持される閉角度に回動規制している。或いは、一対の保持板１２を、例えば板バネやコイルバネ等の弾性体により閉方向に回動付勢するか、流体圧シリンダやソレノイド、モータ等により前後移動してもよい。
【００２７】
前述の容器Ｂは、図４に示すように、上下方向に対して積重ね可能な構造及び形状に形成され、上段側に積重ねられる容器の下面側底面部と、下段側に積重ねられる容器の上面側開口部とを、互いに嵌合及び合致される形状に形成している。且つ、農作物Ａの収容姿勢を保持するのに必要な接触抵抗を有する緩衝部材Ｂａ（例えばウレタンゴムやスポンジゴム等）を容器Ｂの内側底面部に敷設し、様々なサイズの農作物Ａを安定した姿勢に収容及び保持する凹部Ｂｂを、緩衝部材Ｂａ上面に対して所定間隔に隔てて並列状態に複数形成（例えば升目状や千鳥状等）している。
【００２８】
図示実施例は上記の如く構成するものにして、以下、容器運搬台車１により運搬される容器Ｂ…に農作物Ａを収容する作業及び農作物Ａが収容された容器Ｂ…を上下に積重ねて運搬する作業を説明する。
【００２９】
先ず、農作物Ａを収容するまえに、手作業により分離可能な高さに容器Ｂ…が上下に積重ねられた容器運搬台車１を、図１及び図５に示すように、作業者Ｃの手押し力及び牽引力により収穫場所（或いは収容場所）に走行移動した後、容器運搬台車１の容器積載部５に積載された１群の容器Ｂ…を、作業者Ｃの手で保持して上段側及び最上段から１個ずつ分離（図５中仮想線で示す）して、容器運搬台車１の手前側（作業者Ｃ側）に設けた容器受け台６に載置する。
【００３０】
この後、例えば果樹や田畑等で収穫した農作物Ａ…を、図４に示すように、容器Ｂに敷設された緩衝部材Ｂａの凹部Ｂｂ…に対して個々に収容する。また、複数段（例えば２個、３個）の容器Ｂを上段側から一括して分離して容器受け台６に載置するもよい。
【００３１】
次に、所定数の農作物Ａ…が収容された一つの容器Ｂを、作業者Ｃの手で押して積込み方向（図５中の矢印方向）に略水平移動させ、降下位置に待機する容器持上げ機構４の容器持上げ台７に移載する。また、容器運搬台車１の近傍において、収穫した農作物Ａ…を容器Ｂに収容した後、その容器Ｂを容器受け台６に載置するもよい。
【００３２】
次に、図２及び図５にも示すように、作業者Ｃの足で足踏みペダル９を足踏み操作して、リンク機構８を構成する前後一対のリンク８ｂ，８ｂを、図２中仮想線で示す降下状態から図２中実線で示す上昇状態にリンク動作させ、容器Ｂが載置された容器持上げ台７を上方（略鉛直）に上昇させる。
【００３３】
且つ、図３にも示すように、容器Ｂの前後上縁部を、一対の保持板１２の内端側下面部に対して下方から当接し、一対の保持板１２を、容器Ｂの持上げが許容される開角度に回動すると共に、容器持上げ台７に載置された容器Ｂを略水平状態に姿勢を保持したまま、一対の保持板１２よりも上方に持上げる。
【００３４】
且つ、容器Ｂを、一対の保持板１２よりも上方に持上げたとき、一対の保持板１２が、容器Ｂの前後底部に対して係止される閉角度に回動復帰する。この後、容器持上げ台７を、一対の保持板１２よりも下方に降下させると、一対の保持板１２が容器Ｂの前後底部に係止され、農作物Ａ…が収容された一つの容器Ｂを略水平姿勢に支持することができる。
【００３５】
次に、後続の容器Ｂ…を積重ねる場合、上述と同様にして、農作物Ａ…が収容された次の容器Ｂを容器持上げ台７に移載して上方に持上げ、先の容器Ｂを支持する一対の保持板１２を開角度に回動しながら、一対の保持板１２で支持された先の容器Ｂを次の容器Ｂにより持上げ、先に持上げられた容器Ｂの底面側に、次の容器Ｂの上面側を下方から嵌合及び合致して、上下方向に積重ねる。
【００３６】
この後、容器持上げ台７を、一対の保持板１２よりも下方に降下させると、一対の保持板１２が下段側に積重ねられた容器Ｂの前後底部に係止され、農作物Ａ…が収容された２個の容器Ｂを略水平姿勢に支持することができる。
【００３７】
以下、上述と同様して、所定数の農作物Ａ…を、残りの容器Ａに収容する作業と、農作物Ａ…が収容された容器Ｂを上下に積重ねる作業とを数回繰り返して、所定数の農作物Ａ…が収容された容器Ｂを、図５に示す作業者Ｃの手で分離可能な高さに複数段積重ねる（６段）。
【００３８】
次に、１群の容器Ｂ…が積載された容器運搬台車１を、作業者Ｃの手押し力及び牽引力により所定の分離場所（積み下ろし場所）に走行移動して、容器運搬台車１に積載された容器Ｂ…を上段側から１個又は数個ずつ分離すると共に、その積み下ろされた容器Ｂ…を、例えばトラックや列車等の運搬車両に積載して運搬するか、パレットに積重ねてフォークリフトで運搬する等して、例えば選別場や出荷場、保管場所等の取扱い場所に供給する。容器運搬台車１に積載された容器Ｂ…を、例えばフォークリフトやクレーン等の機械により持上げて、取扱い場所に対して一括供給することもできる。
【００３９】
また、容器Ｂ…が積載された容器運搬台車１全体を、上述のような運搬手段により所定の取扱い場所に運搬してもよい。且つ、容器運搬台車１に積載された容器Ｂ…を下段側から１個又は数個ずつ分離して、上述のような運搬手段により所定の取扱い場所に運搬及び供給することもできる。
【００４０】
以上のように、容器運搬台車１の容器積載部５に積載された１群の容器Ｂ…を上段側から１個ずつ分離し、所定数の農作物Ａ…を容器Ｂに収容した後、農作物Ａ…が収容された容器Ｂを、容器持上げ機構４の容器持上げ台７により上方に持上げて複数段積重ねるので、農作物Ａ…が収容された重い容器Ｂを作業者Ｃの手で高所及び高位に持上げる必要がなく、容器Ｂ…を上下に積重ねる作業が簡単且つ容易に行えると共に、作業者に対する負担を少なくし、労力の軽減及び作業性の向上を図ることができる。
【００４１】
且つ、容器Ｂ…を上下に積重ねたまま容器運搬用台車１に積載して、農作物Ａを容器Ｂに収容する収容場所に移動するので、容器Ｂを、農作物Ａを収容する収容場所まで作業者の手で運搬するか、農作物Ａが収容された重い容器Ｂを、容器運搬台車１が置かれた場所まで作業者の手で運搬するような手間及び作業が省けると共に、容器Ｂを運搬する回数が少なくなり、農作物Ａを収容する作業及び農作物Ａが収容された容器Ｂを運搬する作業の能率アップを図ることができる。
【００４２】
且つ、容器積載部５に積載される容器Ｂ…の積重ね高さ及び容器持上げ台７に移載される容器Ｂの移載高さが常時一定しているので、容器Ｂ…を分離するとき、例えば背伸びしたり、支持台を使用したりする必要がなく、また、容器Ｂを積重ねるとき、例えば姿勢を低くしたり、腰を屈めたりする必要がなく、容器Ｂを分離する作業及び積重ねる作業が楽な姿勢で行える。
【００４３】
図６は、容器運搬台車１の他の実施例を示し、容器積載部５に積載された左右２群の容器Ｂ…を上段側から分離し、所定数の農作物Ａ…が収容された２個の容器Ｂを、容器持上げ機構４の容器持上げ台７により左右並列状態に載置したまま上方に持上げて積重ねるので、上述の実施例と略同等の作用及び効果を奏することができる。且つ、多数の農作物Ａ…及び複数群の容器Ｂ…を一括して運搬することができ、作業性の向上及び能率アップが図れる。
【００４４】
また、容器積載部５に積載された前後２群の容器Ｂ…を上段側から分離し、農作物Ａ…が収容された２個の容器Ｂを、容器持上げ機構４の容器持上げ台７により前後並列状態に載置したまま上方に持上げて積重ねる構成も含まれる。

Instead of the wheels 3, for example, casters that freely rotate (approximately 360 degrees) in a desired direction and direction, tires or crawlers (caterpillars) may be attached, or a plurality of them may be combined.
[0019]
The bogie main body 2 includes a container lifting mechanism 4 that lifts a container B containing a predetermined number of agricultural products A upward (substantially vertically) and stacks the predetermined number of containers B one by one from the lower and lower stages. Is provided at the center of the upper part of the bogie main body 2 for holding a predetermined number (six in the embodiment) of containers B... Stacked vertically (substantially vertically).
[0020]
Further, the container B before the crops A ... and the container receiving table 6 on which the containers B containing the crops A ... are once placed is placed below the pair of holding plates 12 described below, and the descent position described later. In addition to being mounted horizontally at a height that is substantially horizontal with respect to the container lifting table 7 that has been placed on standby, it is mounted on the front side (operator C side) of the bogie body 2 and the container lifting table 7.
[0021]
The above-described container lifting mechanism 4 supports the container lifting table 7 formed in a size and a shape on which the container B is placed by a link mechanism 8 disposed at the lower center of the carriage main body 2 so as to be vertically movable and vertically movable. At the same time, a substantially intermediate portion of links 8a and 8b constituting a link mechanism 8 disposed on the front and rear bottom portions of the container lifting table 7 is connected to be rotatable left and right, and the upper end of the link 8a is connected to the left side of the container lifting table 7.

In other words, as shown in FIGS. 2 and 5, the operator C steps with the foot of the foot pedal 9 downward with the foot of the worker C, and rotates the foot pedal 9 up and down around the support shaft 10. A roller 8d attached to the arm 8c of the link mechanism 8 is pushed up by a roller 9a attached to the free end side of the foot pedal 9, and a pair of front and rear links 8b, 8b constituting the link mechanism 8 are imagined in FIG. A reciprocating link operation is performed in a descending state shown by a line and an ascending state shown by a solid line in FIG. 2, and the container lifting table 7 on which the container B is placed is moved in a vertical direction (substantially vertical direction) while being supported in a substantially horizontal state. It moves up and down and moves up and down between a lowering position that is substantially horizontal with respect to the container receiving table 6 and a raising position that is lifted above a pair of holding plates 12 described below.
[0025]
The above-mentioned container loading part 4 is attached with a pair of holding plates 12 locked to the front and rear bottom parts of the container B so as to face the upper end of the frame part 2b erected on the front and rear parts of the bogie main body 2, The container B is provided so as to be vertically rotatable between a closing angle (substantially a horizontal angle) locked to the front and rear bottoms of the container B projecting from the front and rear portions of the container lifting table 7 and an opening angle at which the container B can be lifted.
[0026]
Further, since the holding plate 12 is pivotally supported so as to be vertically rotatable around a portion near the outer end, the inner end is heavier than the outer end, and the closing angle is reduced by the weight of the inner end. Is returned to rotation. Also, the stopper 13 attached to the upper end of the frame 2b is brought into contact with the upper surface of the outer end side of the holding plate 12 which is rotated and returned to the closed angle, and is turned to the closed angle at which the container B is supported in a substantially horizontal state. Regulations. Alternatively, the pair of holding plates 12 may be rotationally biased in the closing direction by an elastic body such as a leaf spring or a coil spring, or may be moved back and forth by a fluid pressure cylinder, a solenoid, a motor, or the like.
[0027]
As shown in FIG. 4, the above-mentioned container B is formed in a structure and shape that can be stacked in the up-down direction, and the bottom side of the container stacked on the upper side and the upper side of the container stacked on the lower side. The openings are formed in shapes that fit and match each other. In addition, a cushioning member Ba (for example, urethane rubber or sponge rubber, etc.) having a contact resistance necessary to maintain the accommodation posture of the crop A is laid on the inner bottom surface of the container B to stably produce the crop A of various sizes. A plurality of concave portions Bb to be accommodated and held in a posture are formed in parallel with each other at predetermined intervals with respect to the upper surface of the buffering member Ba (for example, a grid shape or a staggered shape).
[0028]
The illustrated embodiment is configured as described above. Hereinafter, the operation of accommodating the agricultural products A in the containers B... Transported by the container transport vehicle 1 and transporting the containers B... Explain the work.
[0029]
First, before accommodating the crop A, the container carrier 1 in which the containers B are vertically stacked at a height that can be manually separated is pushed by the worker C as shown in FIGS. After traveling to the harvesting place (or accommodation place) by the traction force, the group of containers B loaded on the container loading section 5 of the container carrier 1 is The containers are separated one by one from the upper stage (indicated by phantom lines in FIG. 5) and placed on the container receiving table 6 provided on the front side (the worker C side) of the container transporting vehicle 1.
[0030]
Thereafter, for example, agricultural products A harvested in fruit trees or fields are individually accommodated in the recesses Bb... Of the buffer members Ba laid in the container B as shown in FIG. Alternatively, a plurality of (for example, two or three) containers B may be collectively separated from the upper stage and placed on the container receiving stand 6.
[0031]
Next, one container B containing a predetermined number of crops A... Is moved by the operator C's hand and moved substantially horizontally in the loading direction (the direction of the arrow in FIG. 5), and the container lifting mechanism stands by at the lowered position. The container 4 is transferred to the container lifting table 7. Further, in the vicinity of the container carrier 1, the harvested agricultural products A may be stored in the container B, and then the container B may be placed on the container receiver 6.
[0032]
Next, as shown in FIGS. 2 and 5, the foot pedal 9 is stepped on with the foot of the worker C, and a pair of front and rear links 8 b, 8 b constituting the link mechanism 8 are indicated by virtual lines in FIG. 2. The link operation is performed from the lowering state shown to the ascending state shown by the solid line in FIG. 2, and the container lifting table 7 on which the container B is placed is raised upward (substantially vertically).
[0033]
Further, as shown in FIG. 3, the front and rear upper edges of the container B abut against the lower surfaces of the inner ends of the pair of holding plates 12 from below, and the pair of holding plates 12 are lifted. While rotating to an allowable opening angle, the container B placed on the container lifting table 7 is lifted above the pair of holding plates 12 while maintaining the posture in a substantially horizontal state.
[0034]
When the container B is lifted above the pair of holding plates 12, the pair of holding plates 12 return to the closed angle where they are locked to the front and rear bottoms of the container B. Thereafter, when the container lifting table 7 is lowered below the pair of holding plates 12, the pair of holding plates 12 are locked to the front and rear bottom portions of the container B, and the one container B containing the crops A. It can be supported in a substantially horizontal posture.
[0035]
Next, when the following containers B are stacked, in the same manner as described above, the next container B containing the crops A is transferred to the container lifting table 7 and lifted upward to support the previous container B. While rotating the pair of holding plates 12 to the open angle, the previous container B supported by the pair of holding plates 12 is lifted by the next container B, and the next container B is lifted to the bottom side of the previously lifted container B. The upper surface side of the container B is fitted and matched from below, and stacked vertically.
[0036]
Thereafter, when the container lifting table 7 is lowered below the pair of holding plates 12, the pair of holding plates 12 are locked to the front and rear bottoms of the containers B stacked on the lower side, and the agricultural products A are stored. The two containers B can be supported in a substantially horizontal posture.
[0037]
Hereinafter, in the same manner as described above, the operation of accommodating a predetermined number of crops A in the remaining containers A and the operation of vertically stacking the containers B accommodating the crops A. Are stacked at a height that can be separated by a worker C shown in FIG. 5 (six steps).
[0038]
Next, the container transport trolley 1 on which the group of containers B is loaded is moved to a predetermined separation place (unloading place) by the pushing force and the traction force of the worker C, and is loaded on the container transport trolley 1. Containers B ... are separated one by one or several from the upper side, and the unloaded containers B ... are loaded and transported on a transport vehicle such as a truck or a train, or stacked on a pallet and transported by a forklift. For example, it is supplied to a handling place such as a sorting place, a shipping place, or a storage place. The containers B loaded on the container carrier 1 can be lifted up by a machine such as a forklift or a crane, and supplied collectively to a handling place.
[0039]
Further, the entire container transporting trolley 1 on which the containers B are loaded may be transported to a predetermined handling place by the above-described transporting means. Further, the containers B loaded on the container carrier 1 can be separated one by one or several from the lower side, and can be transported and supplied to a predetermined handling place by the above-described transport means.
[0040]
As described above, a group of containers B loaded on the container loading section 5 of the container transporting trolley 1 is separated one by one from the upper side, and a predetermined number of crops A are stored in the containers B. Are lifted up by the container lifting table 7 of the container lifting mechanism 4 and stacked in a plurality of stages, so that the heavy containers B containing the crops A. , The work of stacking containers B vertically can be performed easily and easily, the burden on the operator can be reduced, labor can be reduced, and workability can be improved.
[0041]
In addition, since the containers B are loaded on the container transporting trolley 1 while being vertically stacked and moved to the storage location for storing the crop A in the container B, the worker moves the container B to the storage location for storing the crop A. Or the time and effort of transporting the heavy container B containing the agricultural products A to the place where the container transport trolley 1 is placed by a worker can be saved, and the number of times the container B is transported is reduced. Therefore, the efficiency of the operation for accommodating the agricultural product A and the operation for transporting the container B accommodating the agricultural product A can be improved.
[0042]
Further, since the stacking height of the containers B to be loaded on the container loading section 5 and the transfer height of the containers B to be transferred to the container lifting table 7 are always constant, when the containers B are separated, For example, there is no need to stretch or use a support, and when stacking containers B, for example, there is no need to lower the posture or bend down, and work to separate and stack containers B Work can be done in a comfortable posture.
[0043]
FIG. 6 shows another embodiment of the container carrier 1 in which two groups of left and right containers B loaded on the container loading section 5 are separated from the upper side, and two containers B containing a predetermined number of crops A. The containers B are lifted and stacked while being placed side by side by the container lifting table 7 of the container lifting mechanism 4, so that substantially the same operation and effect as in the above-described embodiment can be achieved. In addition, a large number of agricultural products A and a plurality of groups of containers B can be transported in a lump, thereby improving workability and efficiency.
[0044]
In addition, the two groups of containers B before and after loaded on the container loading section 5 are separated from the upper side, and the two containers B containing the agricultural products A are arranged in front and rear by the container lifting table 7 of the container lifting mechanism 4. It also includes a configuration in which it is lifted upward and stacked while being placed in a state.
