【発明の属する技術分野】
この発明は、穂木苗を挿入して保持する挿入溝を有する保持板と、保持した該穂木苗を引継ぎ挾持して移送する穂木挾持移送装置で挾持した該穂木苗を穂木切断ナイフで切断するが、該保持板は該穂木挾持移送装置が挾持する進行方向手前側から奥側へ向けて下り傾斜状態に設けた技術であり、接木機械として利用できる。
【0002】
【従来の技術】
台木苗は作業者により、例えば、台木受装置へ供給され、この台木受装置からこの台木苗は、台木挾持移送装置の移動により、引継ぎ挾持して回動移動され、この回動移送中、又は停止中に各切断ナイフにより、根鉢部近傍、子葉部、及び胚軸部が順次切断され、切断済み台木苗は接合位置まで回動移送する。
【0003】
又、根鉢部を切断した穂木苗は作業者により、穂木受装置の保持板の挿入溝内へ挿入して供給され、穂木挾持移送装置の移動により、引継ぎ挾持して回動移送されて停止され、この停止中に穂木切断ナイフで胚軸部の所定位置が切断され、切断済み穂木苗は接合位置まで再度回動移送され、切断済み台木苗の子葉部の切断部と、この穂木苗の胚軸部の切断部とが接合されて接木が終了する。
【0004】
【発明が解決しようとする課題】
穂木苗の胚軸部を穂木切断ナイフで切断するときに、この胚軸部が穂木挾持移送装置に設けている。例えば、背当固定板に当接していない状態で切断することにより、胚軸部が逃げて切断面の長さ、及び切断位置等が正確でなくなり、このために接木性能が低下することがあったが、この発明により、これらの問題点を解消しようとするものである。
【0005】
【課題を解決するための手段】
このために、この発明は、台木苗(A)の供給を受けて保持する台木受装置(8)と、台木苗(A)を引継ぎして挾持移送する台木挾持移送装置(10)と、挾持した該台木苗(A)の子葉(G)部を切断する台木子葉切断ナイフ(14)と、穂木苗(B)を挿入して保持する挿入溝(24a)を有する保持板(24)と、保持した該穂木苗(B)を引継ぎ挾持して移送する穂木挾持移送装置(11)と、挾持した該穂木苗(B)の胚軸(F)部を切断する穂木切断ナイフ(15)とを設けた接木機械において、該保持板(24)は該穂木挾持移送装置(11)が挾持する進行方向手前側から奥側へ向けて下り傾斜状態に設け、穂木挾持移送装置(11)は穂木挾持片(38)と該穂木挾持片(38)下側に設けた供給溝(46)を有する支持板(47)と該支持板(47)の下側に開口部(48)を有する背当固定板(45)とを備え、台木受装置(8)には、台木苗(A)を供給する挿入溝(21a)を備える保持板(21)と、該保持板(21)の下側で開閉し閉状態で台木苗(A)の胚軸(E)部を挾持する台木供給片(23)と、保持板(21)の両側壁部に台木苗(A)を検出する透過方式で光電式の台木センサ(22)と、該台木センサ(22)の下側に作業者の手を検出する光電式の手センサ(22a)とを設け、台木センサ(22)が台木苗(A)を検出し且つ手センサ(22a)が作業者の手を検出しない場合に、台木苗(A)の胚軸(E)部を挾持するべく台木供給片(23)を閉状態に作動させる構成とし、台木挾持移送装置(10)に備える台木挾持片(31)の上下両端部及び中央部には上・中・下挾持部材(28,29,30)を設け、前記台木挾持片(31)の上端部には台木苗(A)の胚軸(E)部を所定位置へ案内する三角形状のガイド板(31a,31b)を設けたことを特徴とする接木機械の構成とする。
【0006】
【発明の作用】
台木苗は作業者により、台木受装置へ供給され、この台木受装置からこの台木苗は、台木挾持移送装置の移動により、引継ぎ挾持して回動移動され、この回動移送中、又は停止中に各切断ナイフにより、根鉢部の近傍、子葉部、及び胚軸部が順次切断され、切断済み台木苗は接合位置まで回動移送する。
【0007】
又、根鉢部を切断した穂木苗Bは作業者により、穂木受装置の保持板24の挿入溝24a内へ挿入して供給され、穂木挾持移送装置11の移動により、この穂木苗Bを引継ぎ挾持して回動移送されて停止する。この引継ぎのときに穂木苗Bを保持する保持板24は、該穂木挾持移送装置11が挾持する進行方向手前側から奥側へ向けて下り傾斜状態に設けていることにより、この穂木苗Bの胚軸F部の下端部は、手前側へ向けて傾斜状態となり、この傾斜した穂木苗Bを引継ぎすることにより、該穂木挾持移送装置11に設け背当固定板45に確実に当接状態で引継ぎ挾持して回動移送されて停止され、この停止中の穂木苗Bに穂木切断ナイフ15で胚軸F部の所定位置が切断され、切断済み穂木苗Bは接合位置まで再度回動移送され、切断済み台木苗の子葉部の切断部と、この穂木苗Bの胚軸F部の切断部とが接合されて接木が終了する。
【0008】
【発明の効果】
穂木苗Bを保持する保持板24を傾斜状態に設けたことにより、この穂木苗Bの胚軸F部が傾斜状態で引継ぎされ、これによって胚軸F部は、穂木挾持移送装置11の背当固定板45に当接状態で切断され、胚軸F部が逃げることがなくなり、このために、切断面の長さ、及び切断位置が安定し、安定した接木を行うことができる。又、台木受装置8には、台木苗Aを供給する挿入溝21aを備える保持板21と、該保持板21の下側で開閉し閉状態で台木苗Aの胚軸E部を挾持する台木供給片23と、保持板21の両側壁部に台木苗Aを検出する透過方式で光電式の台木センサ22と、該台木センサ22の下側に作業者の手を検出する光電式の手センサ22aとを設け、台木センサ22が台木苗Aを検出し且つ手センサ22aが作業者の手を検出しない場合に、台木苗の胚軸部を挾持するべく台木供給片23を閉状態に作動させる構成としたので、手センサ22aは子葉Gを検出するような誤検出が防止できて安全性が向上すると共に、台木センサ22で台木苗Aを確実に検出するようにできる。更に、台木挾持移送装置10に備える台木挾持片31の上下両端部及び中央部には上・中・下挾持部材28,29,30を設け、前記台木挾持片31の上端部には台木苗Aの胚軸E部を所定位置へ案内する三角形状のガイド板31a,31bを設けたので、台木苗Aが中央部へ移動することにより接木性能が向上し、上・中・下挾持部材28,29,30により3箇所で挾持することで台木苗Aの胚軸Eの逃げが防止できて切断位置が正確になる。
【0009】
【発明の実施の形態】
以下、本発明の一実施例を図面に基づいて説明する。
図例は、例えば、うり科の内のきゅうりの台木苗Aの子葉G部の切断部Jと、きゅうりの穂木苗Bの胚軸F部の切断部Kとを接合させて接木する接木機械1の穂木受装置aついて図示して説明する。
【0010】
前記接木機械1は、機枠2内下部には、コンプレッサ3、各種電磁弁4、クリップ5を貯留、及び移送するクリップ貯留装置6、及びクリップ移送通路7等を設けている。該機枠2上部には、台木苗A、及び穂木苗Bの供給を受けて保持する台木受装置8、穂木受装置9、これら台木苗A、及び穂木苗Bを引継ぎして挾持移送する台木挾持移送装置10、及び穂木挾持移送装置11を設けた構成である。
【0011】
苗切断装置は、台木苗Aの各部の根鉢C部を切断する台木根鉢切断ナイフ12を装着した台木根鉢切断装置12aと、胚軸E部を切断する台木胚軸切断ナイフ13を装着した台木胚軸切断装置13aと、子葉G部を切断する台木子葉切断ナイフ14を装着した台木子葉切断装置14aと、穂木苗Bの胚軸F部を切断する穂木切断ナイフ15を装着した穂木切断装置15a等よりなる構成である。
【0012】
又、前記接木機械1は、切断済み台木苗Aの切断部Jと、切断済み穂木苗Bの切断部Kとを接合する接合装置16、及び操作装置17等を設けた構成である。
図22、及び図23で示す如くコンプレッサ3内に内装したポンプ3aから、移送ホース3dを経て水抜き用のドレンバルブ3bへ圧縮空気を送風し、このドレンバルブ3bからドレンホース3cを経て排風することにより、水抜きを行う構成であり、地上面から所定位置に設けたこのポンプ3aより、該ドレンバルブ3bを所定位置高所に設けると共に、該移送パイプ3dを折曲して設け、この折曲部へサビ水が溜る構成であり、水抜き操作以外のときは、該ドレンバルブ3b部へサビ水が移動しない構成としている。これにより、サビ水が該ドレンバルブ3b部に停滞しないことにより、長期保管等においても、このドレンバルブ3bの作動不良が発生することがなくなった。
【0013】
前記機枠2の周囲には、各側壁板18を設け、前後両側には、折畳み自在にフレーム19,19を設け、台木苗A、及び穂木苗B等を収納した箱を載置できる構成である。又、各台木・穂木切断ナイフ12,13,14,15等の機能部品の上側には、透明で樹脂材等よりなる機能部品カバー20を開閉自在に設けて、機能部品を覆う構成としている。
【0014】
前記台木受装置8は、機枠2内の後方上部に平行状態に設け、根鉢Cの付いた台木苗Aを作業者が手動により、保持板21の挿入溝21aへ供給すると、この台木苗Aは、自重によって子葉G下部が該保持板21へ当接するまで自然落下し、垂直状態に保持される構成としている。
前記台木受装置8は、図10〜図12で示す如く台木苗Aが保持板21の挿入溝21aへ供給されると、この台木苗Aを検出する透過方式で光電式の台木センサ22,22を該保持板21の両側壁部に設けると共に、作業者の手を検出する反射式で光電式の手センサ22a,22aを該台木センサ22の下部の横側に設けている。これら台木センサ22の検出、及び手センサ22aの未検出に伴って、保持板21下側に開閉自在で開状態に設けた台木供給片23は、閉状態に作動し、台木苗Aの胚軸E部の所定位置を挾持する構成である。これにより、該手センサ22aは子葉Gを検出する誤検出の防止ができて安全性が向上し、又、胚軸E部が曲がった台木苗Aであっても、この台木センサ22で確実に検出することにより、苗の適応性が向上するし、コスト低減になる。
【0015】
前記穂木受装置9は、機枠2内の前方上部に傾斜状態に設け、根鉢D部を切断した穂木苗Bを手動により、保持板24の挿入溝24aへ供給すると、この穂木苗Bは、傾斜状態で自重によって子葉H下部が穂木供給片27へ当接するまで自然落下し、傾斜状態に保持される構成としている。
前記穂木受装置9の保持板24は、図1で示す如く穂木挾持移送装置11が挾持する進行方向手前側から奥側へ向けて所定角度のA度に下り傾斜状態に設けている。これにより、図2、及び図4で示す如く該穂木挾持移送装置11へ引き継ぎ挾持したときには、この穂木挾持移送装置11に設けた背当固定板45に、穂木苗Bの胚軸Fが確実に当接する構成である。これによって、穂木苗Bが該穂木挾持移送装置11へ引継ぎ挾持されたときは、該背当固定板45へ穂木苗Bの胚軸F部が確実に当接することにより、この胚軸F部を穂木切断ナイフ15で切断したときに、切断面の長さ、及び切断位置が安定し、安定した接木ができる。
【0016】
供給された穂木苗Bは、穂木センサ26で検出され、この検出に伴ない、保持板24部に開閉自在で開状態に設けた穂木供給片27は、閉状態に作動されて、穂木苗B胚軸F部の所定位置を挾持する構成としている。
供給された穂木苗Bの子葉H下部が前記穂木挾持片27へ当接していない状態のときには、作業者が手動により、当接するまで引き下げることができる構成である。
【0017】
前記穂木受装置9は、傾斜状態に設けたことにより、穂木苗Bは、傾斜状態に保持される構成である。保持板24上側には、図1、及び図9で示す如く回転ローラ25,25を回転自在に装着した支持板25aを設け、この回転ローラ25,25で穂木苗Bの両側の子葉Hを内側へ向けて押す状態に作用して、この両側の子葉Hを閉状態に保持する構成としている。これにより、穂木苗Bの子葉H部を折り畳み状態で供給ができると共に、穂木苗Bの胚軸F部の曲りを修正することができる。
【0018】
前記穂木供給片27下方部には、作業者の手を検出する手センサ26aを設け、この手センサ26aが手を検出中は、穂木挾持移送装置11を始動させない構成としている。

【0019】
前記台木受装置8に保持された台木苗Aの胚軸E部の所定位置を、台木挾持移送装置10の台木挾持片31が回動移動して挾持する構成であり、これによって挾持された台木苗Aは、台木子葉切断装置14a部へ90度回転移動して、停止する構成としている。
前記台木挾持移送装置10の台木挾持片31,31の上下両端部、及び中央部には、図13、及び図14で示す如く弾性材のゴム、又は樹脂材よりなる上・中・下挾持部材28,29,30を設けると共に、該台木挾持片31,31の上端部には、三角形状のガイド板31a,31bを設け、図15が図16で示す作用の変化の如く台木苗Aの胚軸E部を所定位置へ案内する構成である。これにより、台木苗Aは常に中央部へ移動されることにより、接木性能が向上し、又、上・中・下位置に弾性材の該挾持部材28,29,30を設けて3箇所で挾持することにより、台木苗Aの胚軸Eの逃げが防止できて、切断位置が正確になる。
【0020】
前記穂木挾持移送装置11は、機枠2内前方側に回動自在で、更に引継ぎ挾持する穂木苗Bを垂直状態に挾持して、この穂木苗Bの胚軸F部の切断部K切断面積の拡大を図るべく穂木搬送ローラ、及び穂木搬送ベース等で水平状態に支持させている。又、該穂木挾持移送装置11は、穂木挾持片38、及び背当固定板45等よりなり、開閉、及び移動自在な構成の該穂木挾持片38設けると共に、穂木挾持用シリンダ36により、開閉移動の作動を行わせて、穂木苗Bの胚軸F部の所定位置を挾持する構成としている。
【0021】
前記背当固定板45は、穂木挾持片38下側に設けた供給溝46を有する支持板47の下側にL字形状に形成して設け、この背当固定板45の前面部には、開口48させて、この開口48部の上側で該穂木挾持片38下側位置には、略三角形状の凸部49,49を設け、該背当固定板45の該開口48の上・下側部では、穂木苗Bの胚軸F部の後側部を受けて固定させ、該凸部49,49間では、胚軸F部の両側部を受けて、挾持状態に固定させた構成であり、穂木切断装置15aの穂木切断ナイフ15で胚軸F部を切断のときに、この胚軸F部が切断方向へ逃げることの発生を防止する構成として、これにより、切断したときの切断部Kの切口の長さを常に一定長さとしたり、又、切断位置のずれを防止して、常に一定位置が切断される構成としている。
【0022】
前記穂木受装置9の保持された穂木苗Bの胚軸F部は、穂木挾持移送装置11の穂木挾持片38の回動移動により、引継ぎ挾持される構成であり、これによって挾持された穂木苗Bは、穂木切断装置15a部へ90度回動移動して、停止する構成としている。
前記穂木挾持移送装置11には、図3、及び図9で示す如く回転シリンダ50を設け、この回転シリンダ50の軸端部で穂木受装置9の回転ローラ25,25の下側に位置する状態に、穂木子葉押え板51を開閉自在に設け、穂木苗Bの子葉Hを内側へ向けて押す状態に作用する構成であり、作用は図9の一点鎖線で示す如く移動し、穂木苗Bを引継ぎ位置から接合位置まで移動作用し、移送が終了すると開状態となり、作用しない構成である。これにより、穂木苗Bの子葉H部を閉じた状態で移送、及び胚軸Fの切断位置が正確に切断されることにより、この穂木苗Bの切断不良が防止でき、又、移送時に動かないことにより、接合のときのづれがなくなった。
【0023】
