【０００１】
【産業上の利用分野】
本発明は、育苗箱処理装置に係るものである。
【０００２】
【従来技術】
従来公知の、特開平４−２６２７０３号公報には、播種済の育苗箱を終端に向けて搬送しうる前後方向の播種用移送台の終端に育苗箱を上下に段積し段積した段積育苗箱を段積状態で搬送し得る搬送ローラーを有する育苗箱段積装置を設け、育苗箱段積装置の前側には前記段積育苗箱Ａを移転させる移転部を接続した構成について記載されている。
また、従来公知ではないが、同一出願人による先願の特願平８−１６６７６７号では、播種済の育苗箱を終端に向けて搬送しうる前後方向の移送台の前側に前記育苗箱を順に上下に段積し段積した段積育苗箱を段積状態で搬送し得る育苗箱段積装置を設け、育苗箱段積装置の前側には前記段積育苗箱を移転させる移転部を設け、移転部の左右何れか一側には移動させた段積育苗箱を載置するパレットを搬送するパレット載置台を設け、移転部の左右何れか他側には前記パレット載置台に段積育苗箱を移動させる押出体を有する段積育苗箱移送装置を設けた構成について提案されている。
【０００３】
【発明が解決しようとする課題】
前記公知例は、移転部に移転された段積育苗箱Ａの運搬については提案されていない。
即ち、播種済の育苗箱Ａは発芽室や育苗載置場に運搬するが、水を含んだ土が充填されているので、相当に重く、その運搬は大変である。
また、前記先行技術のものは、段積構成が複雑であり、また押出体を移動させる構成も複雑なためコストが高いという課題がある。
本発明は、播種済の育苗箱を上下に段積し、段積した育苗箱をパレット上に移し替え、このパレットをフォークリフト等の動力機械により運搬するようにしたものである。
【０００４】
【発明の目的】
段積育苗箱の取出の容易化、取出作業の連続化、取出作業の機械化、動力機械による運搬の容易化。
【０００５】
【課題を解決するための手段】
本発明は、播種済の育苗箱Ａを終端に向けて搬送しうる前後方向の移送台１の前側に前記育苗箱Ａを順に上下に段積し段積した段積育苗箱Ａを段積状態で搬送し得る搬送ローラー１４を有する育苗箱段積装置１１を設け、育苗箱段積装置１１の前側には前記段積育苗箱Ａを移転させる移転部１９を設け、移転部１９の左右何れか一側には移動させた段積育苗箱Ａを載置するパレット２４を搬送するパレット載置台２３を設け、移転部１９の左右何れか他側には前記パレット載置台２３に段積育苗箱Ａを移動させる押出体２７を有する段積育苗箱移送装置２５を設け、前記移転部１９は段積育苗箱Ａの移送方向に並設した左右方向の支持ローラー２１と、左右方向に回転する前後一対のチエン２６に固定の押出体２７とにより構成し、前記支持ローラー２１は左右一対の前後方向の前後支持板２０に軸装し、該前後支持板２０の左右両側には前記チエン２６を掛け回した歯車を有する前後方向の回転軸２９と回転軸３１を設け、前記前後支持板２０には前記チエン２６およびチエン２６を支持するチエン支持レール３４を配置させうる切欠部３３を形成し、もって前記チエン２６は支持ローラー２１の前後方向側部に配置し、前記パレット載置台２３側の回転軸３１の上方には前記チエン２６の上方を除き前記支持ローラー２１と前記パレット載置台２３との間に位置する摺動用板４４を設けた育苗箱処理装置としたものである。
本発明は、前記押出体２７の下面は前記支持ローラー２１の上面よりも上方に位置させた育苗箱処理装置としたものである。
本発明は、前記チエン２６を回転させる押出用モータ３６は、前記移転部１９の終端に設けたセンサ４０により回転を開始し、押出体２７が段積育苗箱Ａをパレット載置台２３に押し出して停止後所定時間経過したら自動的に逆転するように構成した育苗箱処理装置としたものである。
本発明は、前記パレット載置台２３は、前記移転部１９の側部に育苗箱段積装置１１から移転部１９への段積育苗箱Ａの移転方向と並行にパレット２４を搬送する搬送ローラー５１を並設し、かつ、複数のパレット２４を前記移転方向に載置し得る大きさに形成し、前記移転部１９の終端より少なくともひとつのパレット２４の長さの載置スペース５０を形成し、前記移転部１９から押し出された段積育苗箱Ａが幅方向に載置されると、段積育苗箱Ａ一列分前方位置だけパレット２４を前進させ、次に段積育苗箱Ａが幅方向に載置されると、パレット２４を載置スペース５０に前進させて取出し、後続のパレット２４を前記移転部１９の側部に位置するようにした育苗箱処理装置としたものである。
本発明は、前記パレット載置台２３の前記移転部１９と対峙する位置には段積育苗箱Ａが幅方向に載置されたことを検出するパレット検知センサ６０を設け、前記移転部１９の終端側部のパレット載置台２３にはパレット２４の前端を検知する基準位置検知センサ５７を設け、基準位置検知センサ５７より段積育苗箱Ａ一列分前方位置には搬送位置検知センサ５８を設け、前記搬送ローラー５１は前記載置スペース５０の部分を除きパレット搬送用モータ５２により駆動回転するようにし、パレット搬送用モータ５２は前記パレット検知センサ６０が段積育苗箱Ａを検知すると、通電され、パレット２４の前端が搬送位置検知センサ５８に至ると停止し、次の段積育苗箱Ａをパレット検知センサ６０が検出すると再通電するように構成した育苗箱処理装置としたものである。
【０００６】
【実施例】
本発明の一実施例を図面により説明すると、１は播種用移送台であり、移送方向に長く形成し、支脚２により床上に載置する。播種用移送台１には育苗箱Ａを移送する移送装置４を設ける。移送装置４は育苗箱Ａを移送できれば構成は問わず、実施例では移送ローラー５を設けている。
播種用移送台１の始端部上方位置には、空の育苗箱Ａを移送手段に自動供給する育苗箱自動供給装置６を設ける。育苗箱自動供給装置６の構成は任意であるが、底抜けの四隅にフレームを起立させて供給する育苗箱Ａの供給用の収容空間を形成し、収容空間の下方の前記移送ローラー５の上方に段積した空の育苗箱Ａのうち下から２段目の育苗箱Ａに係合する上段係合部と、最下段の育苗箱Ａに係合する下段係合部とを交互に出入りさせて一箱づつ前記移送手段に育苗箱Ａを供給する。
【０００７】
しかして、育苗箱自動供給装置６の移送方向下手側（終端側）には床土供給装置７を設ける。床土供給装置７は公知のものであり、上方に供給ホッパーを設け、供給ホッパーの下方に育苗箱Ａの移送方向に回転移動する繰出ベルトを設けて構成している。
床土供給装置７の下手側には種子供給装置８を設ける。種子供給装置８は公知のものであり、上方に供給ホッパーを設け、供給ホッパーの下方に種子繰出部を設けて構成している。種子供給装置種子供給装置８の下手側には、覆土供給装置９を設ける。覆土供給装置９は、床土供給装置７と略同一構成であり、また、同様に公知のものである。
【０００８】
覆土供給装置９の下手側には、早送装置１０を設ける。早送装置１０も公知のものであり、前記移送ローラー５に伝達する歯車の径を小さくして早く回転させる等の構成である。
前記播種用移送台１の終端部には、播種済の育苗箱Ａを段積する育苗箱段積装置１１を設ける。育苗箱段積装置１１は前記播種用移送台１より移送された播種済の育苗箱Ａを摺動載置する前後方向の左右一対の左右受枠１２を前後一対の二組のチエン１３により回動するように設け、左右の左右受枠１２の下方には育苗箱Ａを受け止めて搬送する搬送ローラー１４を並設して構成した受台１５を設けて構成する。１６は前記チエン１３を回転させるモータ、１７は前記搬送ローラー１４の回転軸に設けた歯車に掛け回したチエンである。
【０００９】
前記受台１５は前記播種用移送台１から移送された育苗箱Ａを降ろしながら１０枚程度に段積できるように構成し、台枠１８上に設ける。受台１５より終端側台枠１８には、移転部１９を設ける。移転部１９は前記育苗箱段積装置１１で段積された育苗箱Ａを取出して後続の育苗箱Ａを育苗箱段積装置１１で空いた受台１５に段積できるようにするものであり、左右一対の前後方向の前後支持板２０に支持ローラー２１を所定間隔を置いて軸装する。支持ローラー２１は前記搬送ローラー１４と同じ高さに設定する。前記支持ローラー２１のうち始端側の支持ローラー２１ａは前記搬送ローラー１４の回転を受けて駆動回転するように構成し、その余の支持ローラー２１はフリー回転にする。また、終端側の支持ローラー２１より所定間隔離れた終端側には支持ローラー２１に乗り移った段積育苗箱Ａを停止させるストッパ２２を設ける。
【００１０】
前記移転部１９には、後述するパレット載置台２３上のパレット２４に段積育苗箱Ａを移送させる段積育苗箱移送装置２５を設ける。段積育苗箱移送装置２５は前記支持ローラー２１の前後側に左右方向の前後一対のチエン２６を並設し、チエン２６に支持ローラー２１に乗り移った段積育苗箱Ａを押し出す押出体２７を固定する。前記前後支持板２０には左右方向の左右支持板２８を固定し、左右支持板２８の左右側の一側には回転軸２９を軸装し、回転軸２９には前後一対の歯車３０を設け、また、左右支持板２８の左右側の他側には駆動回転軸３１を軸装し、駆動回転軸３１には前後一対の歯車３２を設け、歯車３０と歯車３２の夫々にチエン２６を掛け回す。
【００１１】
前記前後支持板２０には上側を開口した縦状の切欠部３３を設け、切欠部３３にチエン２６を通るようにすると共に、切欠部３３には夫々左右方向のチエン支持レール３４を配置し、チエン支持レール３４の上面にチエン２６を載せ、チエン支持レール３４は前記前後支持板２０等の固定部に固定する。
前記駆動回転軸３１の端部には受動歯車３５を固定し、受動歯車３５には押出用モータ３６の出力歯車３７との間にチエン３８を掛け回す。
前記ストッパ２２にはセンサ４０を設け、センサ４０により段積育苗箱Ａが移転部１９に乗り移ったことを検知すると、押出用モータ３６を正回転させる。前記チエン２６には突起４１を設け、前記チエン支持レール３４の下側近傍所定位置には戻しスイッチ４２と待機スイッチ４３を設け、パレット２４上に段積育苗箱Ａが移転部１９に乗り移つると、戻しスイッチ４２に突起４１が当接して押出用モータ３６を停止させ停止後所定時間経過すると逆転して押出体２７を待機位置に戻し、待機スイッチ４３に突起４１が当接すると、押出用モータ３６を停止させる。
【００１２】
また、前記駆動回転軸３１の上方には、前記チエン２６の上方位置を除いて、摺動用板４４を設け、支持ローラー２１とパレット２４の間の隙間をなくして段積育苗箱Ａの移送を円滑にしている。また、摺動用板４４の上面は支持ローラー２１と同じか低く形成し、摺動用板４４の上面に対してパレット２４の上面は同じか低く形成し、夫々の間に段差は無い方がよいが、製作誤差を考慮してパレット２４側を低くして確実に押し出せるようにしている。
前記パレット載置台２３は、前記播種用移送台１および移転部１９の側部に並行に設け、複数のパレット２４を載置する長さに構成すると共に、育苗箱段積装置１１より前側（終端側）には少なくともひとつのパレット２４を載置しうる載置スペース５０を形成し、前記パレット載置台２３には段積育苗箱Ａを載置したパレット２４を搬送する搬送ローラー５１を移送方向に並設し、搬送ローラー５１は前記載置スペース５０を除き駆動回転させる。５２はパレット搬送用モータ、５３は歯車、５４はチエン、５５は歯車、５６はチエンである。
【００１３】
前記パレット載置台２３には、前記移転部１９の側部にパレット２４が位置したことを検知する基準位置検知センサ５７と、該基準位置検知センサ５７の段積育苗箱Ａ一列分前方位置には次に段積育苗箱Ａを載置するためにパレット２４の先端が接触する搬送位置検知センサ５８と、前記パレット載置台２３の終端には全停止用検知センサ５９と、また、前記移転部１９の側部のパレット載置台２３の側部には一列パレット２４が位置したことを検知するパレット検知センサ６０とを夫々設ける。即ち、まず、パレット搬送用モータ５２に通電してパレット２４を搬送して、パレット２４の先端位置を基準位置検知センサ５７が検出すると、パレット搬送用モータ５２を停止させて、移転部１９により段積育苗箱Ａを載せ、段積育苗箱Ａは後続の段積育苗箱Ａに押されて横方向に移動して、その列の最後の段積育苗箱Ａが乗り移ると、最初の段積育苗箱Ａをパレット検知センサ６０が検知して、パレット搬送用モータ５２に通電し、パレット２４が段積育苗箱Ａ一列分前進して移転部１９の側方に待機し、次の段積育苗箱Ａを載せる。また、全停止用検知センサ５９と基準位置検知センサ５７とパレット検知センサ６０が同時にオンになると、前記播種用移送台１および育苗箱段積装置１１および移転部１９のすべてを停止させ、載置スペース５０にあるパレット２４を取出して、リセットして再開する。そのため、播種用移送台１の育苗箱自動供給装置６、床土供給装置７、種子供給装置８、覆土供給装置９等のすべておよび灌水装置等に停止機構を設けている。
【００１４】
【作用】
本発明は以上の構成であるから、播種用移送台１の始端部上方位置の育苗箱自動供給装置６に空の育苗箱Ａを供給し、育苗箱自動供給装置６は播種用移送台１の移送ローラー５に育苗箱Ａを一枚ずつ供給する。
一例を示すと、育苗箱自動供給装置６の収容空間に上下に重ねた状態で所定数供給すると、育苗箱自動供給装置６は段積育苗箱Ａの内最下段の育苗箱Ａに下段係合部が係合して全体を支持し、次に、上段係合部が突き出て下から２段目の育苗箱Ａに係合し、下段係合部が引っ込んで最下段の育苗箱Ａのみ移送ローラー５に供給し、次に下段係合部が突き出て上段係合部が引っ込みこれを反復して育苗箱Ａを自動供給する。
【００１５】
移送ローラー５に供給された育苗箱Ａは床土供給装置７により床土が供給され、種子供給装置８により種子が供給され、覆土供給装置９により覆土が供給されて播種が完了する（なお、播種作業の内容は要件ではないので説明を簡略にしており、床土の均平、灌水等は省略している）。
播種された育苗箱Ａは早送装置１０により早送りされて、育苗箱段積装置１１に至り、育苗箱段積装置１１で上下に段積される。実施例では、播種用移送台１の終端に育苗箱段積装置１１を設けているので、空の育苗箱Ａに播種して、播種済の育苗箱Ａを段積するまでを、一連の作業として、連続してでき、作業効率を向上させる。
育苗箱段積装置１１も公知のものであり、作用の説明は簡略するが、二組のチエン１３に設けた左右受枠１２上に育苗箱Ａが乗ると、チエン１３を回転させて左右受枠１２を降下させ、左右受枠１２を受台１５の搬送ローラー１４上に載置すると左右受枠１２が退避し、このとき、別の左右受枠１２が待機位置に待機し、後続の育苗箱Ａが乗り移り、この育苗箱Ａを下降させ、後続の育苗箱Ａが下の育苗箱Ａに重合すると左右受枠１２が退避し、これを反復して１０枚程度に段積する。
【００１６】
育苗箱Ａが上下に段積されると、これを検出してモータ１６に通電し、搬送ローラー１４を駆動回転させて、段積育苗箱Ａを移転部１９に移転させる。移転部１９に段積育苗箱Ａを移転させると、後続の育苗箱Ａを受台１５に段積させる。
段積育苗箱Ａは搬送ローラー１４より移転部１９の支持ローラー２１に乗り移り、搬送ローラー１４の回転と始端側の支持ローラー２１ａの回転により搬送されて、ストッパ２２に当接して搬送が停止される。このとき、段積育苗箱Ａはストッパ２２に当接しているので、支持ローラー２１ａが駆動回転しても問題はなく、支持ローラー２１ａは段積育苗箱Ａが受台１５より取り出されて搬送ローラー１４の回転が停止することにより停止する。
【００１７】
移転部１９の支持ローラー２１に乗り移ってストッパ２２に段積育苗箱Ａが当接すると、押出用モータ３６に通電され、押出用モータ３６はチエン２６を回転させ、チエン２６の回転により押出体２７は支持ローラー２１に乗り移った段積育苗箱Ａを押し出し、押し出された段積育苗箱Ａは移転部１９の側部に設けたパレット載置台２３上のパレット２４上に乗り移る。
しかして、パレット２４の上に押出された先行の段積育苗箱Ａは後続の育苗箱Ａにより押されて移転部１９の反対側に移動し、先行の段積育苗箱Ａがパレット検知センサ６０に当接すると、パレット搬送用モータ５２に通電して、搬送ローラー５１を回転させ、パレット２４を前進させ、パレット２４が段積育苗箱Ａ一列分前進すると、搬送位置検知センサ５８がこれを検知してパレット搬送用モータ５２を停止させる。
【００１８】
次に、パレット２４に段積育苗箱Ａが載ってパレット検知センサ６０が検出すると、パレット搬送用モータ５２に通電してパレット２４は前進し、パレット載置台２３の終端の載置スペース５０に至り載置スペース５０の搬送ローラー５１は回転自由であるので、パレット２４の後端が駆動回転の搬送ローラー５１を通過すると、搬送停止され、回転する搬送ローラー５１により後続のパレット２４は搬送されてその前端が基準位置検知センサ５７に至ると、これが検知されてパレット搬送用モータ５２は停止し、この後続パレット２４上に段積育苗箱Ａを移送し、この間に上に全て育苗箱Ａを乗せた先行のパレット２４はフォークリフトにより発芽室や育苗載置場と呼ばれるビニールハウス等の所望位置に運搬する。なお、パレット２４はフォークリフトによりパレット載置台２３の始端側に載置し、手動スイッチによりパレット搬送用モータ５２に通電すると、駆動回転の搬送ローラー５１により搬送されて移転部１９の側部に至り基準位置検知センサ５７により検知されて押出用モータ３６が停止し、空いたパレット載置台２３の始端側のスペースにはフォークリフトにより次にパレット２４を載置する。
【００１９】
しかして、前記移転部１９は、支持ローラー２１を並設しているが、このうち始端側の支持ローラー２１ａは前記搬送ローラー１４の回転を受けて駆動回転するように構成しているから、受台１５の搬送ローラー１４と同じ搬送速度で段積育苗箱Ａは支持ローラー２１ａにより引き続き搬送されるから、搬送ローラー１４と支持ローラー２１ａとの引継が円滑確実にでき、また、移転部１９に支持ローラー２１ａのみの回転伝達機構を設けないで済むので、構成を簡素にし、終端の支持ローラー２１ａのみ駆動させるので、ストッパ２２に段積育苗箱Ａを押し付けても支障がない。
【００２０】
段積育苗箱Ａは支持ローラー２１の搬送方向に対して交差方向のパレット載置台２３に押し出されるので、段積育苗箱Ａと支持ローラー２１とは線接触となって、移動抵抗を少なくして移動させる。
段積育苗箱Ａを押し出す押出体２７は、前後一対のチエン２６に固定され、一対のチエン２６を回転させる構成なので構成が簡単で、安価にできる。また、チエン２６はチエン支持レール３４により支持されているので、確実に押出体２７を移動させる。また、押出体２７の下面は支持ローラー２１の上面より上方に位置させているから、押出体２７は支持ローラー２１と干渉せずに、段積育苗箱Ａを押し出せる。
【００２１】
支持ローラー２１は左右に配置した前後支持板２０に軸装するが、前後支持板２０には切欠部３３を形成しているから、切欠部３３にチエン２６およびチエン支持レール３４を配置する。即ち、搬送機構は左右方向の支持ローラー２１を前後に並設して構成しているので、交差方向に押し出す押出体２７の回転機構を干渉せずに設けられ、一対の前後支持板２０により前後支持板２０の支持構成とし、一対の回転軸２９と駆動回転軸３１により回転機構として、簡素で合理的な構成にできる。また、前記チエン２６の回転機構としての駆動回転軸３１が存在するために、パレット載置台２３側の支持ローラー２１は短くしているが、パレット載置台２３側の前後支持板２０の上端とパレット載置台２３との間には前記チエン２６の上方位置を除いて、摺動用板４４を設けているから、支持ローラー２１とパレット２４の間の隙間をなくして段積育苗箱Ａの移送を円滑にしている。
【００２２】
押出用モータ３６は押出体２７が段積育苗箱Ａを押し出した後、所定時間経つと、自動的に逆転するので、単にデレイ回路を介して逆転させるという簡単な構成で、出入りを自動化する。
しかして、前記パレット載置台２３は、移転部１９の側部に育苗箱Ａの移送方向と並行にパレット２４を搬送するように配置構成しているから、移転部１９により押し出された段積育苗箱Ａを効率よくパレット２４上に載せると共に、パレット２４の供給・取出を容易にする。
パレット２４の搬送はパレット搬送用モータ５２により駆動回転する搬送ローラー５１により行い、パレット搬送用モータ５２は、センサで制御しているから、パレット２４の供給・取出以外は全自動の連続作業で行える。
【００２３】
【発明の効果】
本発明は、播種済の育苗箱Ａを終端に向けて搬送しうる前後方向の移送台１の前側に前記育苗箱Ａを順に上下に段積し段積した段積育苗箱Ａを段積状態で搬送し得る搬送ローラー１４を有する育苗箱段積装置１１を設け、育苗箱段積装置１１の前側には前記段積育苗箱Ａを移転させる移転部１９を設け、移転部１９の左右何れか一側には移動させた段積育苗箱Ａを載置するパレット２４を搬送するパレット載置台２３を設け、移転部１９の左右何れか他側には前記パレット載置台２３に段積育苗箱Ａを移動させる押出体２７を有する段積育苗箱移送装置２５を設け、前記移転部１９は段積育苗箱Ａの移送方向に並設した左右方向の支持ローラー２１と、左右方向に回転する前後一対のチエン２６に固定の押出体２７とにより構成し、前記支持ローラー２１は左右一対の前後方向の前後支持板２０に軸装し、該前後支持板２０の左右両側には前記チエン２６を掛け回した歯車を有する前後方向の回転軸２９と回転軸３１を設け、前記前後支持板２０には前記チエン２６およびチエン２６を支持するチエン支持レール３４を配置させうる切欠部３３を形成し、もって前記チエン２６は支持ローラー２１の前後方向側部に配置し、前記パレット載置台２３側の回転軸３１の上方には前記チエン２６の上方を除き前記支持ローラー２１と前記パレット載置台２３との間に位置する摺動用板４４を設けた育苗箱処理装置としたものであるから、一枚ずつ移送されてくる育苗箱を段積し、段積した育苗箱を移転部１９から取出すまでを、連続作業で機械化でき、作業効率を向上させることができ、また、前後一対のチエン２６に固定の押出体２７により構成したので、安価にできる効果を奏し、また、左右方向の支持ローラー２１により搬送機構を構成し、交差方向に押し出す押出体２７の回転機構を支持ローラー２１の間に配置できて干渉せずに設けられ、支持ローラー２１の支持構成である一対の前後支持板２０の左右側に回転機構を設けて、簡素で合理的な構成にできる効果を奏し、製造、組立容易にしてコストを低くでき、また、摺動用板４４を設けているから、支持ローラー２１とパレット２４の間の隙間をなくして段積育苗箱Ａの移送を円滑にして、チエン２６の回転機構としての回転軸３１の存在を支障の無いものにして、無駄なく配置構成した効果を奏する。
本発明は、前記押出体２７の下面は前記支持ローラー２１の上面よりも上方に位置させた育苗箱処理装置としたものであるから、段積育苗箱Ａを押し出す押出体２７は、前後一対のチエン２６に固定され、一対のチエン２６を回転させる構成なので構成が簡単で、安価にでき、しかも、押出体２７は支持ローラー２１と干渉せずに、段積育苗箱Ａを押し出せる。

[0014]
[Action]
Since the present invention is configured as described above, an empty seedling box A is supplied to the seedling box automatic supply device 6 located above the starting end of the seeding transfer table 1, and the seedling box automatic supply device 6 is provided on the seeding transfer table 1. The seedling box A is supplied to the transfer roller 5 one by one.
For example, when a predetermined number of the seedling box automatic supply devices 6 are supplied to the accommodation space of the seedling box automatic supply device 6 while being stacked up and down, the nursery box automatic supply device 6 engages with the seedling box A at the lowest stage of the stacking seedling box A. The part engages to support the whole, then the upper engaging part protrudes and engages with the second seedling box A from the bottom, and the lower engaging part retracts to transfer only the lowermost seedling box A Then, the lower engaging portion protrudes, the upper engaging portion retracts, and the seedling box A is automatically supplied by repeating this operation.
[0015]
The seedling box A supplied to the transfer roller 5 is supplied with floor soil by the floor soil supply device 7, supplied with seeds by the seed supply device 8, and supplied with cover soil by the soil covering supply device 9, so that seeding is completed (note that Since the contents of the sowing work are not requirements, the explanation is simplified, and the leveling of the soil and irrigation are omitted).
The sowing seedling box A is fast-forwarded by the fast-forwarding device 10, reaches the seedling-box stacking device 11, and is stacked up and down by the seedling-box stacking device 11. In the embodiment, since the seedling box stacking device 11 is provided at the end of the sowing transfer stand 1, a series of operations until seeding the empty seedling box A and stacking the seeded seedling box A is carried out. As a result, work efficiency can be improved.
The seedling box stacking device 11 is also well known, and the explanation of the operation is simplified. However, when the seedling box A is placed on the left and right receiving frames 12 provided on the two sets of chains 13, the chain 13 is rotated to rotate the left and right receiving frames 12 When the left and right receiving frames 12 are placed on the transport rollers 14 of the receiving table 15, the left and right receiving frames 12 are retracted. At this time, the other left and right receiving frames 12 wait in the standby position, and the subsequent seedling box A is transferred, When this seedling box A is lowered and the succeeding seedling box A is superposed on the lower seedling box A, the left and right receiving frames 12 are retracted, and this is repeated to stack about 10 sheets.
[0016]
When the seedling boxes A are stacked up and down, this is detected, the motor 16 is energized, the transport roller 14 is driven and rotated, and the staged seedling boxes A are transferred to the transfer unit 19. When the transfer seedling box A is transferred to the transfer unit 19, the subsequent seedling box A is stacked on the receiving platform 15.
The stacking seedling box A is transferred from the transport roller 14 to the support roller 21 of the transfer unit 19, transported by the rotation of the transport roller 14 and the rotation of the support roller 21 a on the start end side, abuts against the stopper 22, and transport is stopped. . At this time, since the stacked seedling box A is in contact with the stopper 22, there is no problem even if the support roller 21 a is driven and rotated. The support roller 21 a takes out the stacked seedling box A from the receiving table 15 and carries the transport roller. It stops when the rotation of 14 stops.
[0017]
When the stage growth seedling box A comes into contact with the stopper 22 and moves to the support roller 21 of the transfer unit 19, the extrusion motor 36 is energized, and the extrusion motor 36 rotates the chain 26, and the extruded body 27 is rotated by the rotation of the chain 26. Pushes the stacked seedling box A transferred to the support roller 21, and the pushed stacked seedling box A transfers onto the pallet 24 on the pallet mounting table 23 provided on the side of the transfer unit 19.
Thus, the preceding staged growing seedling box A pushed onto the pallet 24 is pushed by the succeeding seedling box A and moves to the opposite side of the transfer unit 19, and the preceding staged growing seedling box A is moved to the pallet detection sensor 60. The pallet transport motor 52 is energized, the transport roller 51 is rotated, the pallet 24 is moved forward, and the pallet 24 is moved forward by one row, the transport position detection sensor 58 detects this. Then, the pallet carrying motor 52 is stopped.
[0018]
Next, when the stacked seedling box A is placed on the pallet 24 and is detected by the pallet detection sensor 60, the pallet transport motor 52 is energized to advance the pallet 24 and reach the placement space 50 at the end of the pallet placement table 23. Since the transport roller 51 in the mounting space 50 is freely rotatable, the transport is stopped when the rear end of the pallet 24 passes the drive-rotated transport roller 51, and the subsequent pallet 24 is transported by the rotating transport roller 51. When the front end reaches the reference position detection sensor 57, this is detected and the pallet transport motor 52 is stopped, the stacked seedling box A is transferred onto the succeeding pallet 24, and all the seedling boxes A are placed thereon. The preceding pallet 24 is transported to a desired position such as a plastic house called a germination room or a nursery place by a forklift. The pallet 24 is placed on the start end side of the pallet placing table 23 by a forklift, and when the pallet carrying motor 52 is energized by a manual switch, the pallet 24 is carried by a driving rotation carrying roller 51 and reaches the side of the transfer unit 19. The push-out motor 36 is detected by the position detection sensor 57, and the pallet 24 is next placed in the space at the starting end side of the vacant pallet placement table 23 by a forklift.
[0019]
The transfer unit 19 is provided with the support rollers 21 side by side, and the support roller 21a on the start end side is configured to be driven and rotated by the rotation of the transport roller 14, Since the stacked seedling box A is continuously transported by the support roller 21a at the same transport speed as the transport roller 14 of the table 15, the transfer roller 14 and the support roller 21a can be taken over smoothly, and the transfer roller 19 is supported by the transfer roller 19. Since it is not necessary to provide only the rotation transmission mechanism 21a, the structure is simplified and only the terminal support roller 21a is driven. Therefore, there is no problem even if the stage 22 seedling box A is pressed against the stopper 22.
[0020]
Since the stacked seedling box A is pushed out to the pallet mounting table 23 in the direction crossing the conveying direction of the support roller 21, the stacked seedling box A and the support roller 21 are in line contact, and the movement resistance is reduced. Move.
The extrudate 27 that pushes out the stacked seedling box A is fixed to the pair of front and rear chains 26 and rotates the pair of chains 26, so that the configuration is simple and inexpensive. Further, since the chain 26 is supported by the chain support rail 34, the extruded body 27 is moved reliably. In addition, since the lower surface of the extruded body 27 is positioned above the upper surface of the support roller 21, the extruded body 27 can push out the stacked seedling raising box A without interfering with the support roller 21.
[0021]
Although the support roller 21 is mounted on the front and rear support plates 20 arranged on the left and right, the notch 33 is formed on the front and back support plate 20, so the chain 26 and the chain support rail 34 are disposed on the notch 33. That is, since the conveyance mechanism is configured by arranging the support rollers 21 in the left-right direction in the front-rear direction, the conveyance mechanism is provided without interfering with the rotation mechanism of the extruded body 27 pushed out in the intersecting direction. The support structure of the support plate 20 can be configured as a simple and rational structure as a rotation mechanism by the pair of rotation shafts 29 and the drive rotation shaft 31. Further, since the drive rotation shaft 31 as the rotation mechanism of the chain 26 is present, the support roller 21 on the pallet mounting table 23 side is shortened, but the upper end of the front and rear support plate 20 on the pallet mounting table 23 side and the pallet. Since the sliding plate 44 is provided between the mounting table 23 except for the upper position of the chain 26, the gap between the support roller 21 and the pallet 24 is eliminated and the transfer of the staged stacking seedling box A is performed smoothly. I have to.
[0022]
The extrusion motor 36 automatically reverses when a predetermined time elapses after the extrudate 27 pushes out the stacked seedling box A. Therefore, the push-out motor 36 automates the entry and exit with a simple configuration of simply reversing through the delay circuit.
Since the pallet placing table 23 is arranged and configured to convey the pallet 24 to the side of the transfer unit 19 in parallel with the transfer direction of the seedling box A, the tiered seedlings pushed out by the transfer unit 19 are arranged. The box A is efficiently placed on the pallet 24 and the pallet 24 is easily supplied and taken out.
The pallet 24 is transported by a transport roller 51 driven and rotated by a pallet transport motor 52. Since the pallet transport motor 52 is controlled by a sensor, the pallet 24 can be performed in a fully automatic continuous operation except for the supply and removal of the pallet 24. .
