Description

【０００１】
【産業上の利用分野】
この発明は、例えば、茄子、胡瓜、人参、長芋、菜葉、白菜、或いは、蜜柑、林檎、梨、柿、桃等の果菜物を袋詰めしてなる樹脂製又は紙製の袋体を、段ボール製又は樹脂製の箱体に箱詰めする作業に用いられる袋体箱詰め装置に関する。
【０００２】
【従来の技術】
従来、上述例のような茄子を箱詰めする場合、例えば、等階級別に選別された各茄子の上面側に各吸着パッドを夫々密着させて、各吸着パッドに接続した吸引用ブロワの負圧により吸着保持する。各吸着パッドにより吸着保持した各茄子を段ボール箱上方に移動させ、各吸着パッドにより吸着保持した各茄子を段ボール箱内に一括収納した後、各吸着パッドに接続した吸引用ブロワの負圧を遮断又は停止して吸着保持を解除することで、所定本数の各茄子を段ボール箱内に箱詰めすることができる。
【０００３】
【発明が解決しようとする課題】
しかし、上述例のような茄子を箱詰めする場合、各吸着パッドで吸着保持した各茄子を段ボール箱内に一括収納するとき、各吸着パッドで吸着保持した左右の各茄子と段ボール箱とが互いに面接触することがある。つまり、上述した胡瓜や人参等の果菜物に比べて、各茄子と段ボール箱との対向面間に生じる接触抵抗が大きく、その接触抵抗に抗して各茄子を強引に箱詰めしようとすると、各吸着パッドから各茄子が脱落したり、各茄子の吸着姿勢が変位したりするため、所定本数の各茄子を段ボール箱内に対して直接箱詰めすることが困難であるという問題点を有している。
【０００４】
また、所定本数の各茄子を一括包装してなる合成樹脂製の包装袋を段ボール箱内に箱詰めする場合、包装袋内に収納された各茄子の位置及び姿勢が不安定であるため、包装袋の上面側に凹凸ができたり、多数本の皺が付いたりするため、包装袋の上面側に対して吸着パットを隙間無く密着させることが困難であり、一つの包装袋を吸着保持するのに必要な負圧が得られない。上述と同様に、吸着パッドから包装袋が脱落したり、包装袋の吸着姿勢が変位したりするため、包装袋を機械的に箱詰めすることが困難であるという問題点を有している。
【０００５】
この発明は上記問題に鑑み、適宜数の各果菜物を袋詰めしてなる複数個の各袋体を集合して箱体内部に一括投入することにより、複数個の各袋体を箱詰めする作業が機械的に行え、作業の省力化及び能率アップを図ることができる袋体箱詰め装置の提供を目的とする。
【０００６】
【課題を解決するための手段】
請求項１記載の発明は、上面開放形態に形成された箱体を箱搬送コンベアにより袋投入位置に搬送し、該位置に搬送された箱体内部に適宜数の各果菜物を袋詰めしてなる複数個の各袋体を投入する袋体箱詰め装置であって、上記袋投入位置の直上に、上記箱体の上面側開口部と対応する大きさに形成した袋放出口を開口し、上記袋放出口の上面側に複数個の各袋体が並列載置される大きさに形成したシャッターを開閉可能に設け、上記袋投入位置の一側部に、上記シャッターの一側端部に近接して各袋体を搬送するための袋搬送コンベアを配設すると共に、上記袋搬送コンベア上に設定した袋集合位置に、該位置に搬送される複数個の各袋体を箱体内部に対して投入される状態に集合する袋集合手段を設け、上記袋集合位置に集合された複数個の各袋体を上記シャッターの載置面上に一括移動するとともに、該各袋体を箱体内部の前側収納部及び後側収納部と対応する袋投入位置に並列移動させる袋移動手段を設けた袋体箱詰め装置であることを特徴とする。
【０００７】
請求項２記載の発明は、上記請求項１記載の構成と併せて、上記袋集合手段を、上記袋集合位置に搬送される複数個の各袋体を送り方向に対して並列に集合し、該各袋体を箱体内部に対して一括投入可能な状態に集合する袋集合体で構成した袋体箱詰め装置であることを特徴とする。
【０００８】
請求項３記載の発明は、上記請求項１又は２記載の構成と併せて、上記袋移動手段を、上記袋集合位置に集合された複数個の各袋体を上記シャッターの載置面上に一括移動し、該各袋体を箱体の前側収納部及び後側収納部と対応する位置に並列する袋移動体で構成した袋体箱詰め装置であることを特徴とする。
【０００９】
請求項４記載の発明は、上記請求項１，２又は３記載の構成と併せて、上記箱搬送コンベア上に設定した袋投入位置に、上記箱体の開口側周縁部に起立形成された各フラップを外側に開放して供給する箱開放手段を設けた袋体箱詰め装置であることを特徴とする。
【００１０】
【作用】
請求項１記載の袋体箱詰め装置は、上面開放形態に形成された箱体を箱搬送コンベア上の袋投入位置に搬送し、適宜数の各果菜物を袋詰めしてなる各袋体を袋搬送コンベア上の袋集合位置に搬送し、袋集合手段を駆動して、袋集合位置に搬送される複数個の各袋体を箱体内部に対して一括投入される状態に集合する。袋移動手段を駆動して、袋集合位置に集合された複数個の各袋体をシャッターの載置面上に一括移動するとともに、各袋体を箱体内部の前側収納部及び後側収納部と対応する袋投入位置に並列移動させた後、シャッターを開放して、複数個の各袋体を並列に集合した状態のまま袋放出口から放出し、袋投入位置に搬送された箱体内部に対して複数個の各袋体を一括投入することで、箱詰め作業が機械的に行える。
【００１１】
請求項２記載の袋体箱詰め装置は、上記請求項１記載の作用と併せて、袋搬送コンベア上の袋集合位置に各袋体を搬送すると共に、同袋集合位置に搬送される複数個の各袋体を袋集合体により送り方向に並列集合させることで、袋投入位置に搬送された箱体内部に対して複数個の各袋体を並列に集合した状態のまま一括投入することができる。
【００１２】
請求項３記載の袋体箱詰め装置は、上記請求項１又は２記載の作用と併せて、袋搬送コンベア上に設定した袋集合位置に複数個の各袋体を集合した後、同位置に集合された複数個の各袋体を袋移動体によりシャッターの載置面上に一括移動し、箱体の前側収納部及び後側収納部と対応する位置に複数個の各袋体を並列して、袋投入位置に搬送された箱体の前後収納部に対して複数個の各袋体を振分け投入することで、箱体内部の収納空間を有効に活用できる。
【００１３】
請求項４記載の袋体箱詰め装置は、上記請求項１，２又は３記載の作用と併せて、箱開放手段を駆動して、箱体の開口側周縁部に起立形成された各フラップを外側に開放し、同箱体の各フラップを開放した状態のまま袋投入位置に供給することで、袋投入位置に開口した袋放出口に対して箱体の開口側周縁部を近接することができ、箱体内部に対して各袋体を投入するときの落差が小さくなる。
【００１４】
【発明の効果】
この発明によれば、適宜数の各果菜物を袋詰めしてなる複数個の各袋体を箱体内部に順次投入するので、各袋体に袋詰めされた各果菜物の外周面と箱体の内壁面とが面接触するのを確実に防止できると共に、各袋体と箱体との対向面間に生じる接触抵抗が小さくなるため、各袋体の投入作業が容易に行え、各果菜物の商品価値が損なわれるのを防止できる。しかも、複数個の各袋体を並列に集合した状態のまま箱体内部に一括投入するので、各袋体を箱詰めする作業が機械的に行え、箱詰め作業の省力化及び能率アップを図ることができる。
【００１５】
また、複数個の各袋体を箱体内部の前側収納部及び後側収納部と対応する袋投入位置に並列移動させて順次投入するので、箱体内部に投入された各袋体の位置及び姿勢が安定すると共に、箱体内部の収納空間を有効に活用することができ、運搬効率が向上する。且つ、箱体の各フラップを開放した状態のまま袋投入位置に供給し、同位置に開口した袋放出口に対して箱体の開口側周縁部を近接することで、箱体内部に対して各袋体を投入するときの落差が小さくなり、袋投入時に於いて、各果菜物に付与される衝撃を低減することができる。
【００１６】

【００３３】
図示実施例は上記の如く構成するものにして、以下、小袋箱詰め装置１により５袋分の各小袋Ａ…を段ボール箱Ｂ内に箱詰めするときの動作を説明する。
先ず、図１に示すように、各仕分け用コンベア２…により搬送される各茄子Ｎ…の等階級を各等階級判定装置３，３により判定し、各等階級判定装置３，３による判定に基づいて各仕分け位置ａ，ｂ，ｃ，ｄ，ｅに配設した各茄子投入機４…に対して等階級別に各茄子Ｎ…を投入する。各茄子投入機４…から放出される各茄子Ｎ…を各周回用コンベア５…に順次移載し、各周回用コンベア５…により搬送される各茄子Ｎ…を各供給用コンベア６…に順次移載し、各供給用コンベア６…により搬送される各茄子Ｎ…を各茄子包装機７…に順次供給して、図８に示すように、透明又は半透明に形成した合成樹脂製の小袋Ａにより３本ずつ各茄子Ｎ…を一括包装する。各茄子包装機７…から搬出される包装済みの各小袋Ａ…を各袋供給コンベア８…に順次移載し、各袋供給コンベア８…により搬送される各小袋Ａ…を各袋箱詰め機９…に順次供給する。
【００３４】
なお、３本分の各茄子Ｎ…が収納された小袋Ａを閉塞する場合、例えば、熱溶着又は接着等の閉塞手段により閉塞し、或いは、金属製又は樹脂製の閉塞具（図示省略）により閉塞するもよい。
【００３５】
一方、製函工程（図示省略）から供給される上面開放形態の段ボール箱Ｂを搬入用コンベア１１により箱送りコンベア１０上の箱搬入位置に移載する。箱送りコンベア１０上の箱開放位置に段ボール箱Ｂを搬送した後、図２、図３、図４、図５に示すように、箱開放機構１２を駆動して、箱送りコンベア１０上の箱開放位置に搬送された段ボール箱Ｂ内に昇降枠３７を垂直収納し、同昇降枠３７に軸支した各開放板４２…で段ボール箱Ｂの両側縁部及び前側縁部に起立形成された三辺の各フラップＢａ…を外側に開放する。同時に、各開放板４２…により開放された段ボール箱Ｂの各フラップＢａ…を押え板４５で開放した状態に支持する。
【００３６】
次に、段ボール箱Ｂの各フラップＢａ…を押え板４５により開放した状態のまま搬送すると共に、同段ボール箱Ｂの後側上縁部に起立形成されたフラップＢａを押え板４５により外側に開放する。箱送りコンベア１０上の袋投入位置に段ボール箱Ｂを搬送した後、同位置に搬送された段ボール箱Ｂを持上げ板３２により垂直方向に持上げて、同位置上部に開口した袋放出口４７の下面側周縁部に対して段ボール箱Ｂの開口側周縁部を近接することで、段ボール箱Ｂの最下段に対して各小袋Ａ…を投入するときの落差が小さくなる。
【００３７】
次に、図３、図７に示すように、袋投入機構１３を駆動して、袋送りコンベア６２により搬送される各小袋Ａ…の通過を光電センサＳにより検知し、５袋分の各小袋Ａ…が通過したとき光電センサＳによる検知に基づいて、袋送りコンベア６２上に載置された５袋分の各小袋Ａ…を袋集合板６７により順次集合させながら袋集合位置に一括移動し、同位置に垂設した規制板７１に先頭の小袋Ａを当接して、段ボール箱Ｂ内に対して一括投入される状態に５袋分の各小袋Ａ…を各板６７，７１で集合させる。
【００３８】
次に、袋送りコンベア６２上の袋集合位置に集合された５袋分の各小袋Ａ…を前揃え板５３により一括移動させ、各シャッター４８，４８上の袋揃え位置に各小袋Ａ…を並列した状態のまま水平移動する。同時に、各小袋Ａ…を水平移動するとき、袋送りコンベ６２により搬送される後続の各小袋Ａ…を袋集合板６７により一時停止させる。つまり、図９に示すように、段ボール箱Ｂの前側内壁面と平行となる位置に各小袋Ａ…を前揃え板５３で移動し、同段ボール箱Ｂの後側内壁面と平行となる位置に後揃え板５１を移動した後、各シャッター４８，４８を開放して、段ボール箱Ｂの前側内壁面に沿って５袋分の各小袋Ａ…を並列した状態のまま垂直投入することで、１段目の投入動作が完了する。５袋分の各小袋Ａ…を段ボール箱Ｂの最下段に投入した後、持上げ板３２により持上げられた段ボール箱Ｂを垂直降下して箱送りコンベア１０に載置する。
【００３９】
次に、各シャッター４８，４８を閉塞し、各板５１，５３，６７を初期位置に復帰移動させた後、袋送りコンベ６２上に載置された５袋分の各小袋Ａ…を袋集合板６７により順次集合させながら移動し、袋集合位置に垂設した規制板７１に先頭の小袋Ａを当接して、段ボール箱Ｂ内に対して一括投入される状態に５袋分の各小袋Ａ…を各板６７，７１で集合させる。図１０に示すように、段ボール箱Ｂの後側内壁面と平行となる位置に各小袋Ａ…を前揃え板５３で移動し、同段ボール箱Ｂの後側内壁面と平行となる位置に後揃え板５１を移動して、同段ボール箱Ｂの後側内壁面に沿って垂直投入される位置に各小袋Ａ…を規制した後、各シャッター４８，４８を開放して、段ボール箱Ｂの後側内壁面に沿って５袋分の各小袋Ａ…を並列した状態のまま垂直投入することで、２段目の投入動作が完了する。
【００４０】
