【発明の属する技術分野】
本発明は台木用苗及び穂木用苗の茎部を切断し、切断された台木の下部側茎部と穂木の上部側茎部とをその切断個所で接合固定させる接ぎ木装置に関する。
【0002】
【発明が解決しようとする課題】
この種接ぎ木装置にあっては、例えば搬送ラインによって運ばれる台木及び穂木用苗が、所定位置まで移動したとき、把持機構の上下把持ハンドによって各苗の茎部を把持して持上げ茎部の略中間をカッタによって切断し、切断された台木の下部側茎と穂木の上部側茎とをその切断面個所にて接合させるようにした手段がある。このような手段にあって上下把持ハンドで苗を把持する場合、搬送ライン上の所定位置の苗に対し、上下把持ハンドをその苗位置まで移動させて苗の把持を行うものであるが、把持を行う苗に次工程の苗が絡み付いた状態のとき、次工程の苗の一部まで把持ハンドで把持するなどして接ぎ木作業に悪影響を与えていた。
【0003】
【課題を解決するための手段】
したがって本発明は、苗を植立させた苗の供給搬送ラインと、該搬送ライン上の苗の茎部を上下の把持ハンドで把持する苗把持手段と、この把持の際苗規制板によって苗を適正姿勢に保持する苗規制手段と、把持後苗の上下把持間を切断する苗切断手段とを備え、前記規制板による苗の規制動作時に次工程の供給苗位置まで規制板を移動可能に設け、該規制板でもって次工程の供給苗を把持位置の苗より離反させるように設けて、例えば規制板によって苗姿勢を適正に保って把持ハンドに苗を把持しようとするとき、次工程の供給苗位置まで規制板の移動ストロークを延長させて、規制板によって次工程の供給苗を把持位置の苗より反対方向に押しやる状態とさせて、絡み付いた苗の強制分離を行うもので、特別の分離機構を設ける必要なく現行の苗規制手段を有効利用して接ぎ木作業の能率を向上させるものである。
【0004】
【発明の実施の形態】
以下、本発明の実施例を図面に基づいて詳述する。図1は苗引き寄せ機構の側面説明図、図2は全体の概略平面図、図3は概略正面図、図4は把持移送機構部の正面説明図であり、接ぎ木手段である接ぎ木装置(1)は、穂木搬送コンベアである穂木用苗搬送ライン(2)と台木搬送コンベアである台木用苗搬送ライン(3)と挿し木手段である接ぎ木済苗搬送ライン(4)とを平面視で平行状に配置するもので、各搬送ライン(2)(3)(4)上に載置される各トレイ(5)には、穂木用苗(H)、台木用苗(D)、接ぎ木済苗(S)のそれぞれ複数本を収納可能とするポット部(5a)を平面視マトリックス状に形成している。
【0005】
そして図5にも示す如く、左端にある穂木用苗搬送ライン(2)と中央にある台木用苗搬送ライン(3)とでトレイ(5)を、矢印a方向に前記ポット部(5a)の間隔(P)毎に間欠的に搬送させ、苗把持手段である苗の把持移送機構(6)、切断手段である切断機構(7)、クリップ搬送機構(8)等を配置した門型フレーム(9)の下方個所で各種作業を実行させ、図17に示す如く接ぎ木用のクリップ(10)により台木用苗(H)の根元側と穂木用苗(D)の先端側とを接ぎ木された接ぎ木済苗(S)を、接ぎ木済苗搬送ライン(4)において、前記両搬送ライン(2)(3)のトレイ(5)の搬送方向と逆向きの矢印b方向に前記ピッチ(P)にて間欠搬送させるように構成している。
【0006】
また、接ぎ木済苗搬送ライン(4)の側方であって、門型フレーム(9)の下方には、不要となった台木用苗(D)の上側茎部を集めるための廃棄箱(11)を設置し、その廃棄箱(11)の上側方近傍には、クリップ(10)を1個づつクリップ搬送機構(8)に供給するためのクリップフイーダ(12)を配置させている。
【0007】
図4乃至図6にも示す如く把持移送機構(6)は、前記穂木用苗搬送ライン(2)及び台木用苗搬送ライン(3)のトレイ(5)(5)から穂木用苗(H)を6本、台木用苗(D)を6本、合計12本の苗を一挙に把持するもので、1本の苗につきその根元側と先端(上端側)の茎部(上下2個所)を上下の把持ハンド(13)(14)にて挾持し、この上部把持ハンド(13)群を支持する上部移送フレーム(15)と下部把持ハンド(14)群を支持する下部移送フレーム(16)とを一体的に所定高さ(C)だけ上昇させるように構成している。
【0008】
またこれら把持ハンド(13)(14)による苗(H)(D)の挾持の際、図7、図9、図10、図11に示す如き下部把持ハンド(14)の下側に設けるカミソリなど穂木及び台木用根鉢切断刃(17)(18)が苗(H)(D)の根鉢部(h)(d)近傍の茎を切断し、トレイ(5)のポット部(5a)に不要な根鉢部(h)(d)を残したまま、葉茎部だけを上下把持ハンド(13)(14)で把持して所定高さ(C)だけ持上げ、この高さ(C)位置において上下把持ハンド(13)(14)の間に切断機構(7)のカッタ(19)を進出させて各6本の苗(H)(D)の茎部を軸線に対して斜め切りするように構成している。
【0009】
そして、茎が切断された穂木及び台木用苗(H)(D)の下部側茎を挾持した下部把持ハンド(14)の下部移送フレーム(16)は距離(L1)(1ライン幅分)横移動させて、穂木及び台木用苗(H)(D)の下部側茎を台木用及び接ぎ木済苗搬送ライン(3)(4)のトレイ(5)上に位置させるように構成している。
【0010】
また、上部把持ハンド(13)群の上部移送フレーム(15)は、前記茎が切断された12本の苗の上部側茎を挾持したまま若干寸法(C1)(図示せず)だけ上昇させた後、穂木用苗(H)の上部側茎が接ぎ木済苗搬送ライン(4)のトレイ(5)の上方に位置し、且つ台木用苗(D)の上部側茎が廃棄箱(11)上に位置するように距離(L2)(前記距離(L1)の2倍)だけ横移動させた後、上部把持ハンド(13)群を所定寸法(C1)だけ下降させて、穂木用苗(H)の上部側茎を台木用苗(D)の下部側茎部の切断面に接合させるもので、またこのとき前記接ぎ木済苗搬送ライン(4)のトレイ(5)の上方にて、クリップ搬送機構(8)に予め装填されたクリップ(10)を前記各苗(D)(H)の接合部に接近させて挾持固定して接ぎ木済苗(S)を形成するように構成している。なお(20)は各機構(6)(7)(8)などの駆動用エアコンプレッサ、(21)は制御用中央処理装置である。
【0011】
さらに接ぎ木作業を終了した接ぎ木済の6本の苗(S)は、前記把持移送機構(6)を所定高さ(C)分だけ下降させるとき、接ぎ木済苗搬送ライン(4)のトレイ(5)の各ポット部(5a)に予め収納される固形培地(22)に、茎の下端茎部を挿し込んで、上部把持ハンド(13)及び下部把持ハンド(14)を開いて茎の把持を開放することによって、接ぎ木済苗搬送ライン(4)のトレイ(5)に収納するように構成している。またこの場合不要となる穂木用苗(H)の切断刃(17)とカッタ(19)間寸法分の短茎が、下部把持ハンド(14)の開き動にて台木用苗搬送ライン(3)上の根鉢部(d)の残ったトレイ(5)に廃棄され、また不要となった台木用苗(D)における先端側茎は、上部把持ハンド(13)の開き動にて廃棄箱(11)に向って自然落下して廃棄されるように構成したものである。
【0012】
次に、把持移送機構(6)の細部構成について、図4乃至図6を参照しながら説明する。把持移送機構(6)の昇降枠(23)は、門型フレーム(9)の上面板に固定した昇降用エアシリンダ等の第1昇降アクチュエータ(24)にて、穂木用搬送ライン(2)及び台木用苗搬送ライン(3)の上面に対して大きく上下動するように設け、該昇降枠(23)には、距離(L1)だけ横移動する横移動用エアシリンダ等の第1横移動アクチュエータ(25)を介して12対の下部把持ハンド(14)を備えた下部移送フレーム(16)を装着させている。
【0013】
また、昇降枠(23)の前面の上下ガイドレール(26)に横移動用エアシリンダ等の第2横移動アクチュエータ(27)を上下動自在に配置し、この第2横移動アクチュエータ(27)を、昇降枠(23)に固定させたエアシリンダ等の第2昇降アクチュエータ(28)で距離(C1)だけ上下動するように装着させて、前記第2横移動アクチュエータ(27)にて、12対の上部把持ハンド(13)を備えた上部移送フレーム(15)を距離(L2)だけ横移動するように構成している。
【0014】
さらに、台木用苗(D)(穂木用苗(H)とも共通する)の下部側茎を挾持する下部把持ハンド(14)の基部は、切断機構(7)から遠い対向側に位置し、台木用苗(D)の上部側茎を挾持する上部把持ハンド(13)の基部は切断機構(7)に近い対向側に位置し、上部把持ハンド(13)の左右支持体(13a)(13b)の拡狭移動機構と、下部把持ハンド(14)の左右支持体(14a)(14b)の拡狭移動機構とは同一構成とするもので、下部把持ハンド(14)における拡狭移動機構にて代表して説明すると、図6に示すように、下部移送フレーム(16)における上下等の対の横長のガイド軸(29)(29)に、左右一対の摺動支持片(30a)(30b)と左右一対の摺動支持片(31a)(31b)を左右摺動自在に嵌設させ、一対の摺動支持片(30a)(30b)に前記下部把持ハンド(14)の12本の左支持体(14a)を一定間隔にて取付ける横杆(32)を固着させ、他方の一対の摺動片(31a)(31b)に、前記12本の右支持体(14b)を一定間隔で取付ける横杆(33)を固着する。
【0015】
そして、図4及び図6において、下部移送フレーム(16)の左端に設けた拡狭移動用アクチュエータ(34)のピストンロッド(35)を摺動支持片(30a)に固定する一方、下部移送フレーム(16)の右端に設けた拡狭移動用アクチュエータ(36)のピストンロッド(37)を摺動支持片(31b)に固定し、左右両拡狭移動用アクチュエータ(34)(36)のピストンロッド(35)(37)を伸出動させるとき、左右支持体(14a)(14b)の左右間隔を狭まるように横杆(32)(33)を横移動させて、左右支持体(14a)(14b)先端の挾持片(38a)(38b)にて台木用苗(D)(穂木用苗(H))の根元側茎を左右から挾持するように構成したものである。
【0016】
また前述とは反対にピストンロッド(35)(37)を退入動させるとき、左右支持体(14a)(14b)の左右間隔を拡がらすように横杆(32)(33)を横移動させ、左右支持体(14a)(14b)先端の挾持片(38a)(38b)を前記茎を放すように拡がらせるものであり、上部移送フレーム(15)においても、拡狭移動用アクチュエータ(34)(36)及び横杆(32)(33)を介して左右支持体(13a)(13b)を左右移動させて、この先端の挾持片(38a)(38b)にて台木用苗(D)(穂木用苗(H))の先端側茎を挾持したり、この茎を放したりするものである。
【0017】
図6、図7、図9にも示す如く、前記挾持片(38a)(38b)は、断面L字状に形成され、水平板部の内辺には茎を囲むように案内できる平面視略V字状の案内溝(39)を形成し、前記挾持片(38a)(38b)には、挾持するときの茎の損傷を防止するためのスポンジ等の四角立方形の軟質弾性体(40)を固着させている。
【0018】
次に、図5、図7、図8に基づいて切断機構(7)について説明する。切断機構(7)におけるカッタ(19)は前記把持移送機構(6)と対向した位置に台木用苗(D)(穂木用苗(H))の搬送方向上流側から各茎に対して接近して押し切り、図7に示す如く茎の軸線に対して斜めに切断するものであって、前記把持移送機構(6)にて挾持されて所定高さまで持上げられた台木用苗(D)及び穂木用苗(H)を12本一挙に切断するとき、各苗の茎部がカッタ(19)の押し切りに対して逃げ移動しないようにするため、上部把持ハンド(13)と下部把持ハンド(14)との上下間にて、カッタ(19)の付属部材である左右一対の把持片(41a)(41b)にて茎の位置を拘束した後に、カッタ(19)を前方に押し進めることによって各茎の切断を行うように構成している。
【0019】
また、前記切断用フレーム(42)は門型フレーム(9)に対して高さ位置不変に保持され、切断用フレーム(42)には、前記12本の左把持片(41a)の基部を支持する横杆(43)と右把持片(41b)の基部を支持する横杆(44)とが左右移動可能に支持されると共に、切断用フレーム(42)に取付けられたエアシリンダ等の把持移動用アクチュエータ(45)に前記横杆(43)(44)を連結させて、アクチュエータ(45)動作でもって左右把持片(41a)(41b)の間隔の拡大及び縮小を行うように構成している。
【0020】
一方、切断用フレーム(42)の前後方向(矢印a方向)に移動可能に支持させた支持フレームには12本の丸棒、角棒、板状等のカッタ軸(46)を一定間隔にて突出させ、カッタアクチュエータ(47)によりカッタ軸(46)を介しカッタ(19)を前方に移動させて上下をハンド(13)(14)によって把持される苗(D)(H)の茎を切断するように構成している。
【0021】
図9及び図11に示す如く、穂木及び台木用苗(H)(D)に対する下部把持ハンド(14)の左右支持体(14a)(14b)のうち、茎部の最下端側を挾持する挾持片(38b)の下面側には、前記V字状の案内溝(39)に臨ませて前記根鉢切断刃(17)(18)を固着していて、トレイ(5)上の苗(H)(D)の茎部を挾持すべく左右両側の挾持片(38a)(38b)の間隔を縮めたとき、前記切断刃(17)(18)にて茎の根元側を切断し、後に苗(H)(D)の茎上部側(葉部)を上方に引上げるとき、苗(H)(D)の根鉢部(h)(d)をトレイ(5)のポット部(5a)に残したままとして、苗(H)(D)の茎上部側持上げ時の苗姿勢を安定保持させるもので、またこの切断の際苗(H)(D)を挟んで切断刃(17)(18)の対向位置に設ける受刃(48)によって切断時の苗姿勢を安定保持させて確実な切断を行うように構成している。なお前記受刃(48)には長穴(49)を開設して、該受刃(48)上に塵や土などが乗っても、前記長穴(49)よりこれらを下方に落下させて、受刃(48)上に塵や土などが堆積するのを防止している。またこの場合台木用苗(D)は穂木用苗(H)より茎部の長さの長い品種を用いて固形培地(22)に直接的に挿し木するため、台木用苗(D)の挾持片(38a)(38b)及び弾性体(40)も長尺に形成したものである。
【0022】
また前記固形培地(22)にはパーライト、バーミキュライト、ピートモスなど用土を固めたもので、中央に接ぎ木済苗(S)の茎基部の挿入する挿し木孔(22a)を設けていて、接ぎ木終了後クリップ(10)により切断面が接合保持される接ぎ木済苗(S)が、把持移送機構(6)により所定高さ(C)分だけ下降するとき、接ぎ木済搬送ライン(4)のトレイ(5)に予め収納する固形培地(22)の挿し木孔(22a)に、苗(S)の茎基部が挿入して挿し木されるように構成している。
【0023】
つまりこの接ぎ木作業にあっては、台木用苗(D)は穂木用苗(H)より茎軸長の長い品種を用いて接ぎ木済苗(S)を得るものであって、穂木及び台木用苗(H)(D)は上下把持ハンド(13)(14)によって茎の上下部が挾持されるとき、根元側が各切断刃(17)(18)によって切断されて根鉢部(h)(d)が切り落とされ、次に茎の略中央がカッタ(19)によって斜め切りされ、穂木用苗(H)の上部側と台木用苗(D)の下部側の斜め切り口が接合されるとき、クリップ(10)の圧着によるこの接合保持が行われて接ぎ木済苗(S)が形成され、接ぎ木済苗(S)が搬送ライン(4)近傍まで下降するとき、搬送ライン(4)上に待機する固形培地(22)に挿し木されるもので、根鉢の形成に影響されることのない良好な接ぎ木作業を可能にできる。
【0024】
ところで図1、図12乃至図16に示す如く、前記把持移送機構(6)による苗(H)(D)の把持時に、各苗(H)(D)の茎部の姿勢を上下2枚1組の苗規制板である苗引き寄せ板(50)(51)によって規制する苗姿勢規制手段である苗引き寄せ機構(52)を、トレイ押え杆(53)先端側に設けるもので、本体フレーム(54)に基端を固設して各搬送ライン(2)(3)上に門形に配設する杆ベース(55)に電動・空圧・或いは油圧モータ・シリンダなどからなるアクチュエータ(56)及びガイド(57)を介して摺動自在に押え杆(53)基端の取付ホルダー(58)を支持させ、押え杆(53)の水平下面部で搬送ライン(2)(3)上のトレイ(5)上端面を摺接案内するように設けている。
【0025】
また、前記押え杆(53)先端上面の前後に立設する前後ガイド軸(59a)(59b)ガイド孔(60)を介して前後摺動自在にスライド板(61)を取付け、該スライド板(61)に立設する支軸(62)の上下に平面視略L形状の左右苗引き寄せ板(50)(51)の基端をそれぞれ上下にラップさせて回動自在に枢支させると共に、各左右苗引き寄せ板(50)(51)に円弧状に形成する開閉用のカム溝(63)を前ガイド軸(59a)に係合させて、図16に示す如く前後ガイド軸(59a)(59b)の案内によって、スライド板(61)を押え杆(53)の先端方向(後方向)に摺動させるとき、カム溝(63)の案内によって左右苗引き寄せ板(50)(51)を狭めてこれら最外側部間巾(E1)を隣り合う苗(H)(H)・(D)(D)の最内側部間巾(E2)より小とさせて、苗(H)(D)に当接させることなく苗(H)(H)・(D)(D)間を通過させる一方、スライド板(61)を押え杆(53)の基端方向(前方向)に摺動させるとき、両翼を拡げる状態に引き寄せ板(50)(51)の先端側を外側に拡張させて、左右苗引き寄せ板(50)(51)の前端作用面(50a)(51a)を横一線状とさせ、次に押え杆(53)によって苗(H)(D)の茎部に作用面(50a)(51a)を当接させて一定距離だけ引き戻すとき、苗(H)(D)を引き起して傾いたり曲がった苗を略垂直の適正姿勢に保って、上下把持ハンド(13)(14)による確実な把持動作を行わしめるように構成している。
【0026】
前記スライド板(61)は、折曲不可能なピアノ線或いはワイヤなど線体(64)を介して押え杆(53)と一体の電動・空圧・油圧式のモータ或いはシリンダからなるアクチュエータ(65)の作動部(65a)の取付板(66)に連結させて、前記アクチュエータ(65)の伸縮動作によって線体(64)を押引動作させるとき、各引き寄せ板(50)(51)の開閉を行うもので、前記押え杆(53)を動作させるアクチュエータ(56)の作動部(56a)の取付板(67)に、前記ホルダー(58)と共に引き寄せ板開閉用アクチュエータ(65)を取付けて、2つのアクチュエータ(56)(65)によって引き寄せ板(50)(51)の前後方向の移動と開閉を行うように構成したものである。
【0027】
而して該構成の場合、図16に示す如く左右引き寄せ板(50)(51)の閉から開となるときの最先端動作軌跡(A)が円周率の大きな円弧状のものとなって、開閉に要する占有面積(A1)(軌跡(A)で囲まれる部分)の割合を小さなものとさせて、他の苗を引掛けたり他の苗に当接させる確率を大巾に低減させることができるものである。
【0028】
さらに、前記押え杆(53)を動作させるアクチュエータ(56)は、把持位置の苗(H)(D)より後方の次工程の供給苗(H1)(D1)位置までストロークを伸張させて、最後方位置まで移動するとき開とさせる左右引き寄せ板(50)(51)の横一線状の後端作用面(50b)(51b)で次工程の供給苗(D1)(H1)を後方に押圧移動させる状態とさせて、前方位置の現工程の苗(H)(D)に対し次工程の供給苗(H1)(D1)を強制分離させてこれらの絡み付きを解消させるように構成している。
【0029】
またさらに、左右引き寄せ板(50)(51)の上面先端側に欠株センサ(68)をそれぞれ設置していて、該センサ(68)の苗検出板(68a)を後端側作用面(50b)(51b)より後方に臨ませて、後端側作用面(50b)(51b)で次工程の供給苗(H1)(D1)を後方に押圧移動させるとき、同時に苗検出板(68a)をこの供給苗(H1)(D1)の茎部に当接させて、苗(H1)(D1)の有無を検知し次工程の供給苗(H1)(D1)の欠株の検出を行うように構成している。
【0030】
図18はこのフローチャートを示すもので、把持ハンド(13)(14)の把持位置で把持作業が終了し左右引き寄せ板(50)(51)が後方に移動するとき、左右引き寄せ板(50)(51)を閉とさせ、またこの間においては各搬送ライン(2)(3)上の苗(H)(D)を1ピッチ(P)分前移動させて、把持位置には新規な苗(H)(D)を供給し、そして左右引き寄せ板(50)(51)が最後方近傍位置まで移動するとき、左右引き寄せ板(50)(51)を開とさせて、最後方位置となるとき、後端側作用面(50b)(51b)を次工程の供給苗(H1)(D1)に当接させて、該苗(H1)(D1)を後方に押しやる状態とさせて、この前方の把持位置の苗(H)(D)との絡み付きなどを解消させるもので、またこの際左右引き寄せ板(50)(51)に設ける欠株センサ(68)が苗(H)(D)の無(欠株)を検出するとき、警報ブザー或いはランプなど警報装置を作動させて欠株を作業者に報知させる一方、正常時には開状態を保持したまま左右引き寄せ板(50)(51)を前方の把持位置に移動させて、把持位置の苗(H)(D)の引き起しを行うものである。
【0031】
【発明の効果】
以上実施例から明らかなように本発明は、苗(H)(D)を植立させた苗の供給搬送ライン(2)(3)と、該搬送ライン(2)(3)上の苗(H)(D)の茎部を上下の把持ハンド(13)(14)で把持する苗把持手段(6)と、この把持の際苗規制板(50)(51)によって苗(H)(D)を適正姿勢に保持する苗規制手段(52)と、把持後苗(H)(D)の上下把持間を切断する苗切断手段(7)とを備え、前記規制板(50)(51)による苗の規制動作時に次工程の供給苗(H1)(D1)位置まで規制板(50)(51)を移動可能に設け、該規制板(50)(51)でもって次工程の供給苗(H1)(D1)を把持位置の苗(H)(D)より離反させるように設けたものであるから、例えば規制板(50)(51)によって苗姿勢を適正に保って把持ハンド(13)(14)に苗(H)(D)を把持しようとするとき、次工程の供給苗(H1)(D1)位置まで規制板(50)(51)の移動ストロークを延長させて、該規制板(50)(51)によって次工程の供給苗(H1)(D1)を把持位置の苗(H)(D)より反対方向に押しやる状態とさせて、絡み付いた苗の強制分離を行うもので、特別の分離機構を設ける必要もなく、現行の苗規制手段(52)の有効利用によって、接ぎ木作業の能率向上化を図ることができるなどの顕著な効果を奏するものである。
