Description

【0001】
【産業上の利用分野】
この発明は、苗を植え付けるとともに施肥を行う施肥田植機に関する。
【0002】
【従来の技術】
従来、特開昭61−111617号公報に、上下に開口したホッパ−の下側に外周面に繰出溝が形成されたロ−ル形状の繰出ロ−ルを回転可能に内装した繰出装置を連結し、該繰出装置の下側に肥料移送管を連結した施肥装置を装着し、前記繰出装置を複数個左右横並びに配設するとともに、各繰出装置内の繰出ロ−ルを機体左右方向に向く軸に取り付けた施肥田植機が開示されている。そして、この施肥田植機においては、繰出装置内の繰出ロ−ルを抜き取ってメンテナンスを行うときは、繰出ロ−ルが取り付けられた左右方向に向く軸に沿って前記繰出ロ−ルを繰出装置内から機体左右方向に抜き取るようになっている。
【0003】
【発明が解決しようとする課題】
従来の施肥田植機では、繰出装置内の繰出ロ−ルを機体左右方向に抜き取るようになっているので、隣接する繰出装置とに挟まれた狭い空間へ繰出ロ−ルを抜き取ることになり、その抜取り作業が非常にやりにくかった。
【0004】
【課題を解決するための手段】
上記課題を解決するために、この発明は、上下に開口したホッパ−50の下側に外周に繰出溝55aが形成されたロ−ル形状の繰出ロ−ル55を回転可能に内装した繰出装置51を連結し、該繰出装置51の下側に肥料移送管52を連結した施肥装置5を装着した施肥田植機において、前記繰出ロ−ル55を機体前後方向に軸心が向く繰出ロ−ル軸55fに取り付けて前記繰出装置51を複数個左右横並びに配設し、繰出装置51の後側に設けた駆動側ギヤ57aの前側部分に繰出ロ−ル55と一体回転する従動側ギヤ55gを噛み合わせて繰出ロ−ル55へ伝動する構成とし、開口部DSを各繰出装置51に設けて繰出ロ−ル55を前側へ移動させて前記開口部DSから抜き取り可能に構成すると共に、繰出ロ−ル55の前側への移動で従動側ギヤ55gを駆動側ギヤ57aから離して非噛み合い状態に切替可能に構成したことを特徴とする施肥田植機とした。
【0005】
【発明の作用及び効果】
この発明の施肥田植機は、繰出ロ−ル55を機体前後方向に軸心が向く繰出ロ−ル軸55fに取り付けて繰出装置51を複数個左右横並びに配設するとともに、繰出装置51の後側に設けた駆動側ギヤ57aの前側部分に繰出ロ−ル55と一体回転する従動側ギヤ55gを噛み合わせて繰出ロ−ル55へ伝動する構成とし、開口部DSを各繰出装置51に設けて繰出ロ−ル55を前側へ移動させて前記開口部DSから抜き取り可能に構成したので、繰出装置51内の繰出ロ−ル55を抜き取ってメンテナンスを行うとき、開口部DSから繰出装置51の前側の開放された空間へ繰出ロ−ル55を抜き取ることになり、その抜取り作業が非常にやりやすくなって、メンテナンス時の作業性が向上する。また、繰出ロ−ル55の前側への移動で従動側ギヤ55gを駆動側ギヤ57aから離して非噛み合い状態に切替可能に構成したので、繰出装置51の繰出作動の停止を簡単に行える。
【0006】
【実施例】
この発明の一実施例を図面に基づき説明する。
乗用田植機1は、走行車体2の後側に昇降作動する昇降リンク装置3を介して苗移植機4が装着されて構成されている。また、走行車体2の後部側に施肥装置5が配設されている。
【0007】
走行車体2は、左右一対の操舵用の駆動回転する前輪6・6と左右一対の駆動回転する後輪7・7を備えている。また、前側にミッション8が配され、そのミッション8の左右側部から前輪アクスルフレ−ム9・9が固着され、そのフレ−ム9・9の両端部に前輪ファイナルケ−ス10・10が連結されて、そのケ−ス10・10下側から外側に突出する前輪車軸に前輪6・6が取り付けられている。ミッション8内の動力が、前輪アクスルフレ−ム9・9、前輪ファイナルケ−ス10・10内の伝動機構により伝達され、前輪6・6が駆動回転する。また、ミッション8の後側部にフレ−ム11・11の前端部が固着している。フレ−ム11・11の後端部は横フレ−ム12に固着し、その横フレ−ム12の中央部の軸受部に後輪フレ−ム13の左右中央部に前後水平に軸心を向けて固着した後輪ロ−リング軸13aが嵌合している。後輪フレ−ム13の左右に端部に後輪ギヤケ−ス14・14が固着し、その後輪ギヤケ−ス14・14の外側部から横に突出する後輪車軸に後輪7・7が取り付けられている。よって、ミッション8とフレ−ム11・11、横フレ−ム12で構成される車体フレ−ムに対し、後輪7・7が取り付けられている後輪フレ−ム13が後輪ロ−リング軸13a回りにロ−リングできるようになっている。ミッション8内の動力がその後側部から左右の後輪ギヤケ−ス14・14に後輪伝動軸14a・14aで伝動され、後輪7・7が駆動回転される。また、ミッション8への動力入力は、フレ−ム11・11上に支持したエンジンEから第1ベルト伝動装置15(15a:エンジン側プ−リ−、15a’:エンジン出力軸、15b:油圧ポンプ側プ−リ−、15b’:油圧ポンプ駆動軸、15c:伝動ベルト)でミッション8上に固設した油圧ポンプPに一旦伝動され、そこからミッション8の入力軸に無段変速式の第2ベルト伝動装置16(16a:油圧ポンプ側割プ−リ−、16b:ミッション側割プ−リ−、16b’:ミッション入力軸、16c:伝動ベルト。両割プ−リ−16a・16bは副変速レバ−27にて背反的にプ−リ−幅が調節されるようになっている。)で高低速無段階で変速可能に伝動される。また、苗移植機4への伝動は、ミッション8の右側部から後方に向けて突出させた植付施肥駆動軸24に第一伝動軸25が連結し、その後端がリンクベ−スフレ−ム31に取り付けられた植付施肥クラッチケ−ス26の入力軸に連結する。植付施肥クラッチケ−ス26内に入力された動力は、苗移植機4への伝動を断続する植付クラッチを経て植付施肥クラッチケ−ス26の後側部に突出する植付駆動軸26aに伝動し、また、施肥装置5への伝動を断続する施肥クラッチを経て植付施肥クラッチケ−ス26の後側部に突出する施肥駆動軸26bに伝動する。そして、植付駆動軸26aから植付伝動軸27を介して苗移植機4の植付伝動ケ−ス40の入力軸に伝動し、施肥駆動軸26bからは駆動ア−ム28、クランクロッド29、クランクア−ム30を介して施肥装置5の施肥伝動軸57に伝動する。
【0008】
尚、エンジンEに取り付けられたオルタネ−タGにはエンジンEの第2出力軸から第3ベルト伝動装置17により伝動され、そこで発電された電気は、施肥装置5の肥料搬送用の圧風を起こすブロア53のモ−タ−Mに接続されブロアが電動するようになっている。
また、走行車体2には、その前部に前輪6、6を操向するハンドル18が設けられ、エンジンEの上側を覆うエンジンカバ−19の上に座席20が取り付けられている。また、座席20及びハンドル18の周囲下側にはステップフロア21が水平状に設けられていて、機体の左右両側において前端側から後部側にわたって操縦者或は他の作業者が自在に移動することができ、また、右側と左側との間を自在に移動することができる。機体の乗り降りも機体の左右に固設された昇降ステップ22、22からだけではなく、機体前端左右側からフロア21上に乗り降りできる。更に、ハンドル18の下側はポストカバ−23で覆われ、そのポストカバ−23の上部には各種作動状態を表示する表示パネル部が設けられている。また、その表示パネル部およびその周辺には、左側に主変速レバ−と後輪デフロックレバ−、右側に副変速レバ−、アクセルレバ−が配設されている。尚、ポストカバ−23の下側後側には操縦者が足で踏み込んで操作するペダルが設けられ、左側にはクラッチペダル、右側には後輪サイドクラッチ・ブレ−キペダルが設けられ、更に座席20の前側フロア部上に前輪デフロックペダルが設けられいる。また、左右の前輪アクスルフレ−ム9・9の上部に固着された支持フレ−ム61a・61aに補給用の苗を上下多段に載せる予備苗載台61…・61…が取り付けられている。
【0009】
昇降リンク装置3は、フレ−ム11・11の後側に固着されたリンクベース31に回動自在に取り付けられた上リンク32および下リンク33・33を備え、これら上下リンクの後端部に縦リンク34が連結されている。そして、縦リンク34の下端部から後方に突出する軸受部に苗移植機4の伝動ケース40に固着の連結軸40aが回動自在に連結して、苗移植機4が進行方向に対して左右に回動(ロ−リング)自在に装着される。エンジンE下方でフレーム11・11に固着の支持部材に油圧シリンダ35の基部側を枢支し、ピストンロッド側を上リンク31の基部に一体で下向きに延びるスイングアーム31aの先端部にスプリングを介して連結している。油圧シリンダ35を伸縮作動させると昇降リンク装置3が昇降作動し、苗移植機4が昇降するようになっている。この油圧シリンダ35は油圧バルブ36によって切り換え作動する。
【0010】
苗移植機4は、6条植えの構成になっていて、平面視E字状の伝動ケース40が苗移植機4のフレームを兼ね、該伝動ケース40の上側に前側が上位となるよう傾斜して苗載台41が設けられている。この苗載台41は伝動ケ−ス40内の左右往復移動機構と連結して左右に往復移動するようになっている。また、伝動ケース40の後端部に植付条数分の植付装置42…を備え、苗載台41が左右に往復動して台上の苗を該苗載台の下端側に設けた苗受け枠41aの苗取出口に順次供給しつつ、植付装置42…の植付具43…が所定の軌跡を描きながら回転して、前記苗取出口に供給された苗を植付具43…の植付爪が保持し、その保持した苗を圃場に達したとき押し出して植え付けるようになっている。また、苗載台21の各条苗載面下位側にはベルト式の苗縦送り装置44が設けられていて、苗載台41が左右方向に移動して、植付装置42…が苗載面上に載せられた苗の下端部を一列分移植し終えると、次に移植されていく下端部を苗取り口上に位置するよう苗を移送する。また、苗移植機4の下部には、中央にセンターフロート45、左右に一対のサイドフロート46・46が、それぞれ前端部側が上下動するよう後部が枢支されて取り付けられている。センターフロート45は、圃場面の凹凸を検出するセンサでもあり、このセンサーフロート45の前端部側の上下動に応じて油圧バルブ36が作動するようになっている。即ち、センターフロート45が上動すると油圧シリンダ35を伸ばす方向に油圧バルブ36が作動され、逆にセンターフロート45が下動すると油圧シリンダ35を縮める方向に油圧バルブ36が作動されるものである。また、各フロート45・46・46には、各条の苗植付位置の左右近傍位置に施肥用の溝を形成する作溝器47…が取り付けられている。
【0011】
施肥装置5は、各植付位置に左右近傍に施肥する側条施肥装置で、まず、肥料を収容するホッパ−50とそのホッパ−の下側に取り付けられる繰出装置51…を、前後方向に対して苗移植機4の前側で走行車体2の座席20の後側に位置させ、且つ施肥個所と同数の繰出装置51…(ここでは6条植えに対応して6体の繰出装置が設けられる)が左右に一列に横並びに設けている。そして、繰り出された肥料を作溝器47…の後側に導く施肥ホ−ス52…を各繰出装置51…にそれぞれ連結する。更に、ブロア53とそのブロアからの圧風を一時的に貯えて施肥ホ−ス52…の上端部へ送るエア−チャンバ−54とが備えられて、施肥ホ−ス52…内に圧風を送りその圧風により肥料が強制的に移送されるようになっている。
【0012】
以下、施肥装置5の各部の構成を説明する。
ホッパ−50は、左右に長い箱状のホッパ−で、その内側は各条ごとに仕切られていない。ホッパ−上部は全体が上方に開放した肥料投入口50aが設けられ、その肥料投入口50aには後側軸回りに回動させて開閉可能な蓋50bが取り付けられている。ホッパ−底部は、その下側に取り付けられた各繰出装置51…の肥料流入口51aに連通する肥料落流下口50c…が設けられ、その肥料落流下口50c…に向かって肥料が流れ落ちるように傾斜している。尚、蓋50bの枢支部内側には、帯状のシ−ト50dが取り付けられていて、蓋50bを後側が高位になる姿勢に開けて肥料を投入するとき、投入された肥料が蓋50b上に落ちてもシ−ト50dによりその肥料はホッパ−内へ流れ落ちていく。
【0013】
繰出装置51は、上部に肥料流入口51a、下部に肥料繰出口51bを設けた繰出ケ−ス51’内に定量づつ肥料を上から下へ繰り出す繰出ロ−ル55が内装されている。繰出装置ケ−ス51’は、その上部がホッパ−50の底部と連結して、繰出装置ケ−ス51’の肥料流入口51aとホッパ−50の肥料流下口50cとが連通状態となっている。また、下部には漏斗51cが取付けられ、肥料繰出口51bから繰り出されて落ちてくる肥料をその漏斗51cが受けるようになっている。繰出ロ−ル55は、肥料流入口51aに入り込んだ肥料が下側の肥料繰出口51bに流れ落ちるのを堰き止めるように繰出ケ−ス51’に組み込まれている。そして、繰出ロ−ル55の外周には、軸心X方向に並行する繰出溝55a…が複数個所に一定間隔で設けられて、その繰出溝55a…内に肥料流入口51aに入り込んだ肥料が入り込んだ状態で繰出ロ−ル55が回転すると、繰出溝55a…内に保持された肥料が下側に移送され肥料繰出口51bへ落下するようになっている。また、繰出ロ−ル55が下方に向かって回動する側には、ブラシ51dが繰出ロ−ル55の外周面に摺接するように着脱自在に組み付けられている。これにより、繰出ロ−ル55の繰出溝55a…に入り込んだ肥料は、繰出ロ−ル55の回転により移送されるとき、そのブラシ51dによりそがれて肥料が定量づつ繰り出されるようになっている。尚、漏斗51cの下部は横向き筒状のホ−ス取付部51c’が一体的に形成されていて、そのホ−ス取付部51c’の後端口には施肥ホ−ス52が嵌合し、前端口はエア−チャンバ−54のエア−吹出し口に挿入して連結している。
【0014】
ブラシ51dは、ノブ付きボルトで繰出装置ケ−ス51’内に締め付け固定されており、取外すときは繰出装置ケ−ス51’の左右一方側の側部に設けられた蓋51eを開き、前記ボルトを緩めれば容易に取り外すことができる。このとき、蓋51eを開くとともに、その蓋51eの内側に取り付けられた肥料取出しプレ−ト51fが肥料繰出口51bへの肥料の流下を妨げない位置から肥料繰出口51gへの肥料の流下を阻止する位置に移動するので、肥料繰出口51bに肥料を流すことなくホッパ−50内の肥料を蓋51eが開かれて開放された肥料取出し口51gから取り出すことができる。肥料取出し口51gから抜き落される肥料は、繰出装置51…の間に取り付けられる樋56…上に流れ落ちる。樋56…は、前側が下位になるように傾斜して設けられているので、その下端部に肥料を受け入れる袋の口を持っていけば、ホッパ−50内の肥料は袋に戻すことができる。尚、各条の繰出装置51…は、2条ごとに互いに接近した状態で配設され、それにより繰出装置51…間の間隔が広くなった側に肥料取出し口51g…が設けられ、また、左右端位置の繰出装置51・51の肥料取出し口51g・51gはそれぞれ左右外側に設けられている。
【0015】
施肥ホ−ス52…は、繰出装置51…の漏斗51c…下部に一体的に設けられたホ−ス取付部51c’…から作溝器47…の後側に設けた施肥ガイド部47a…を繋ぐように設けられた可撓性の肥料移送用導管である。尚、このホ−ス52…の下端口と施肥ガイド部47a…との連結部は伸縮自在の蛇腹状連結部材52aで連結していて、施肥ホ−ス52…がフロ−ト45・46・46の上下動の抵抗にならないようになっている。
【0016】
ブロア53は、電動モ−タ−で送風ファンが駆動回転する構成で、その圧風吹き出し口53aをエア−チャンバ−54の左右一端部の圧風吹込み口54aに連結させて、エア−チェンバ−54の長手方向に圧風が吹き込むように取付けられている。また、ブロア53の吸い込み口53bにはダクト53cが取り付けられ、エンジンカバ−19内の暖気を吸い込むようになっている。尚、エア−チェンバ−54の圧風吹込み口54a側とは反対側の開口部54bは着脱可能な蓋54cで塞がれている。また、エア−チャンバ−54は、左右に長い鉄パイプで構成されていて、リンクベ−ス31の上部に固着されている。このエア−チャンバ−54に各条の繰出装置51…が取り付け支持されている。また、エア−チャンバ−54の左右両端側の前側部にはサイドステップ60・60が下方に折り畳み可能に取り付けられている。
【0017】
ところで、繰出装置51の繰出ロ−ル55は、機体前後方向に向かう軸心X回りに回動するように設けられている。また、その繰出ロ−ル55は、外周に軸心X方向に並行する繰出溝55a…が形成された駆動ロ−ル55bと、各繰出溝55a…に係合する溝係合部55c…がクシ歯状に形成された溝長さ調節ロ−ル55dとで構成されている。溝長さ調節ロ−ル55dには、繰出量調節ダイヤル55eが回動自在且つ軸方向には一体的に摺動するように取り付けられ、その繰出量調節ダイヤル55eが溝長さ調節ロ−ル55dとともに繰出ケ−ス51’の側部に組み付けられる側面視E字状の繰出量調節側支持部51’aのダイヤル軸部51’bに係合される。ダイヤル軸部51’bの外周はネジ加工されていて、繰出量調節ダイヤル55eはそのネジに捩じ込まれて係合する。また、繰出ケ−ス51’の凹んだ後側壁に設けた軸孔から前側に向けて繰出ロ−ル軸55fが組み込まれる。この繰出ロ−ル軸55fは、後端部にベベルギヤ部55gが一体形成されている。繰出ロ−ル軸55fの前側には、繰出ケ−ス51’内において、まず、駆動ロ−ル55bがキ−を介して一体回転するよう嵌合し、次に、溝長さ調節ロ−ル55dと繰出量調節ダイヤル55eとが取り付けられた繰出量調節側支持部51’aがそのダイヤル軸部51’bに設けられた繰出ロ−ル軸孔に繰出ロ−ル軸55fを挿通させて取り付ける。繰出ロ−ル軸55fは、繰出量調節側支持部51’aの外側部に突出し、その突出部に止め輪SR1が嵌められる。繰出量調節側支持部51’aは、その上部と下部に後方に向けて突出する係合部51’c・51’cが繰出ケ−ス51’前側部の上下に形成した係合ガイド51’d・51’dに嵌入させて組み付けられる。
【0018】
よって、メンテナンス等で繰出ロ−ル55を繰出ケ−ス51’内から抜き取るときは、繰出ロ−ル軸55fの前端部に嵌められている前記止め輪SR1、ワッシャW1を外した後、繰出量調節側支持部51’aを前方に引き出す。このようにするだけで、繰出量調節ダイヤル55eと溝長さ調節ロ−ル55d、そして駆動ロ−ル55bを簡単に、繰出ロ−ル軸55fに沿って引き抜くことができる(図7参照)。尚、図7に示すように、繰出ケ−ス51’前側部に組み込まれた後述するダストシ−ルDSの内径部分が、繰出ロ−ル55を機体前方向に抜き取るための開口部となる。
【0019】
尚、繰出ロ−ル軸55fのベベルギヤ55gと繰出ケ−ス51’の後側壁の間にはコイルスプリングSPが介装されている。また、繰出ケ−ス51’前側部と溝長さ調節ロ−ル55dの間にはその隙間を塞ぐようにダストシ−ルDSが組み込まれている。更に、繰出ロ−ル55の前後に仕切り部材56・56が外嵌する状態でケ−ス51’内に固定されて設けられ、その仕切り部材56・56により繰出ケ−ス51’内での肥料の通路が前後に仕切られる。
【0020】
また、繰出ロ−ル55の繰出溝55a…の溝長さの調節は、繰出量調節ダイヤル55eを回動操作することで可能となり、それにより肥料繰出量の調節が可能となる。即ち、繰出量調節ダイヤル55eはダイヤル軸部51’bのネジに沿って回動すると軸方向に移動し、それとともに溝長さ調節ロ−ル55dが軸方向に移動し、繰出溝55a…の溝長さが変わる。尚、駆動ロ−ル55bは、ダイヤル軸部51’bの内端部と駆動ロ−ル55bの後側に嵌められた止め輪SR2より軸方向には摺動不能に組まれている。また、繰出ロ−ル55が回転するときに摩擦により繰出量調節ダイヤル55eが連れ回りしないように、繰出量調節側支持部51’aに固定された板バネSTが繰出量調節ダイヤル55eの外周歯に係合するように設けられている。尚、板バネSTは大きく撓めばダイヤル55eの外周歯を乗り越えられるように設けられていて、繰出ロ−ル55の回転による連れ回りを防止しつつ、繰出量調節のための繰出量調節ダイヤル55eの回動操作は可能とする。
【0021】
施肥装置5の伝動構成は以下のようになっている。即ち、植付施肥クラッチケ−ス26の施肥駆動軸26aに駆動ア−ム28が一体回転するように取り付けられ、その駆動ア−ム28の先端部にクランクロッド29が取り付けられる。そして、そのクランクロッド29の上端部は、左右に横長の施肥伝動軸57にワンウエイクラッチ58・58を介して外嵌させたボス30aに固着するクランクア−ム30の先端部に連結する。よって、施肥駆動軸27の回転は、クランクア−ム30を上下に揺動し、ワンウエイクラッチ58・58によりクランクア−ム30の下動時に施肥伝動軸57を駆動して、施肥伝動軸57に間歇回転伝動する。施肥伝動軸57は、各条繰出装置51…の左右横並び方向に並行して設けられ、その左右軸端部は、エア−チャンバ−54の左右両端部に固着されたブラケット59・59に設けた軸受メタル59a・59aで軸受され、更に、各条繰出装置51…の繰出ケ−ス−51’…の後側部とそこに着脱自在に取り付けられた繰出駆動側支持部51’e…との間に形成される軸受け孔部51’f…にも回転自在に軸受けされる。また、施肥伝動軸57には、各条繰出装置51…の後側位置において繰出ロ−ル軸55f…のベベルギヤ部55g…に噛み合うようにベベルギヤ57a…が一体回転するように組み付けられる。よって、施肥伝動軸57の回転は、ベベルギヤ57a…とベベルギヤ部55g…の噛み合いにより、各条繰出装置51…の繰出ロ−ル軸55f…に伝動し、各条繰出装置51…の繰出ロ−ル55…が伝動回転する。51’g・51’gは、繰出駆動側支持部51’eを繰出ケ−ス51’に固定するフックである。
【0022】
尚、繰出装置51…の繰出作動を停止させたいときは、停止させたい繰出装置51の繰出量調節側支持部51’aを、繰出ロ−ル軸55fの前端部に嵌められている止め輪SR1を外すことなく前方に引き出す。こうすると、繰出ロ−ル軸55fが一体的に前方に引き出され、繰出ロ−ル軸55fのベベルギヤ部55gが施肥伝動軸57のベベルギヤ57aから非噛み合い状態に離れて、施肥伝動軸57から繰出ロ−ル軸55fへの伝動が断たれ、その繰出装置51の繰出作動が停止する(図8参照)。尚、前方に引き出した繰出量調節側支持部51’aがコイルスプリングSPにより後方に引き戻されないよう係止する手段が講じられている(図9)。即ち、繰出ケ−ス51’の係合ガイド51’d・51’dの左右側部に孔71・71が設けられ、その孔にスチ−ルボ−ル72・72がスプリング73・73で付勢された状態で止め輪SR3・SR3で止められて押し込まれ、スチ−ルボ−ル72・72が孔71・71の内側に突出した状態になっている。繰出量調節側支持部51’aの係合部51’c・51’cを係合ガイド51’d・51’dに後方へスライドさせながら嵌入させると、係合部51’c・51’cに設けた切欠き部74・74・74・74にスチ−ルボ−ル72・72が係合したとき、繰出量調節側支持部51’aは仮固定されるようになっている。切欠き部74…は、繰出装置51の繰出作動状態となる個所と繰出停止状態となる個所に繰出量調節側支持部51’aが仮固定されるよう設けられている。
【0023】
よって、以上よりこの施肥田植機は、繰出装置を複数個左右横並びに配設するとともに、各繰出装置内の繰出ロ−ルを機体前後方向に抜き取るための開口部を各繰出装置に設けているので、繰出装置内の繰出ロ−ルを抜き取ってメンテナンスを行うとき、繰出装置の前後の開放された空間へ繰出ロ−ルを抜き取ることになり、その抜取り作業が非常にやりやすくなって、メンテナンス時の作業性が向上する。
