Description

【０００１】
【発明の属する技術分野】
本発明は、ベニヤレースによって切削された湿潤状態のベニヤ単板、あるいはこの湿潤状態のベニヤ単板をベニヤドライヤによって乾燥した乾燥後のベニヤ単板を巻取った巻取りリールの搬送制御方法及び装置に関するものである。
【０００２】
【従来の技術】
従来より、ベニヤレースで切削された湿潤状態のベニヤ単板１は、図７に示すように、搬入コンベヤ２上を搬送され、その終端のプーリ３から適宜距離だけ離隔して設置されたサイドドライブロール４と圧接回転する巻取りリール５によって巻き取られ、巻取りを完了した巻玉６は、昇降装置７を介してリール支柱８内を上昇し、巻玉ストックエリア９の一対のレール１０上へ移送される。この一対のレール１０は進行方向（巻戻し位置）に対して若干の下り勾配として敷設されている。また、巻戻し位置にてベニヤ単板１が巻戻され、空となった巻取りリール５は、リールストックエリア１１の一対のレール１０へ移送される。この一対のレール１０は進行方向（巻取り位置）に対して若干の下り勾配として敷設され、空の巻取りリール５が巻取り位置に至ると、サイドドライブロール４上まで下降させて、新たな巻取りを開始している。また、ベニヤドライヤによって乾燥されたベニヤ単板１においても、上記とほぼ同様に巻取りリール５によって巻取られ、リール支柱８内を上昇して巻玉ストックエリア９の一対のレール１０上へ移送される。
【０００３】
湿潤状態のベニヤ単板１を巻取り、巻玉６化された巻取りリール５は、ベニヤドライヤの入側に設置された巻戻し位置に至るまで、巻玉ストックエリア９の一対のレール１０上を、下り勾配による転動状態で移送される。また、乾燥後のベニヤ単板１を巻取った巻取りリール５は、例えば、仕組み工程に設置された巻戻し位置に至るまで、上記記載と同様に、一対のレール１０上を下り勾配による転動状態で移送されることになる。
【０００４】
【発明が解決しようとする課題】
巻玉ストックエリア９のレール１０上、あるいはリールストックエリア１１のレール１０上を下り勾配によって転動する巻取りリール５は、終端に配置される巻戻し位置、あるいは巻取り位置では勿論のこと、移送される途上の適当な位置で、ストッパが作動して巻取りリール５を停止させている。巻取りリール５は、一対のレール１０上を慣性力で転動しており、この状態のまま、搬送面より突出した上昇位置で待機しているストッパの上部に衝突して停止するのであるが、衝撃荷重によってストッパを構成する機器、及び／又は巻取りリール５に損傷が及ぶことになる。
【０００５】
また、巻取りリール５が一対のレール１０上を転動するとき、進行方向に向かっていずれかへ偏位して蛇行搬送することがある。この偏位状態が著しくなると、レール１０上を転動する巻取りリール５のベアリング部分（図示略）がレール１０の軌条間隔を規制している両壁部分のいずれか一方へ衝止して、その状態のまま転動状態が停止することになる。この停止状態が発生する都度、作業者が巻玉ストックエリア９のレール１０上へ至って人為的作業によってこの停止状態を解除することになる。このため、作業性が低下するばかりか、作業者にとっては高所作業による危険が伴うことになる。さらには、レール１０及び／又は巻取りリール５のベアリング１４部分の損傷が及び、安全管理上にも問題が波及することになる。
【０００６】
そこで、本発明はベニヤレースによって切削された湿潤状態のベニヤ単板、あるいはこの湿潤状態のベニヤ単板をベニヤドライヤによって乾燥した乾燥後のベニヤ単板を巻取った巻取りリールを、一対のレール上を搬送制御させることによって停止時における衝撃の発生の緩和、並びに作業性の低下等を防止させることにある。
【０００７】
【課題を解決するための手段及び作用・効果】
上記課題を解決するために、本発明の巻取りリールの搬送制御方法は、
平行に設置された一対のレールに、ベニヤ単板が巻き付けられて巻玉となった巻取りリールを搬送体によって下流側へ移動可能とさせ、移動方向に隣接する前記巻取りリール同士を任意の間隔に制御することを前提とする。
【０００８】
ベニヤ単板は巻取り面にその幅方向に渡って巻取られ、巻玉化された巻取りリールのベアリングが、巻玉ストックエリア９の一対のレール上に乗せられる。この平行に設置された一対のレールはベニヤ単板の巻き戻し位置に向かってほぼ水平に敷設されているか、或いはベニヤ単板の巻き戻し位置に向かって若干下り勾配に敷設されている進行方向に対して若干下り勾配として敷設されている。
【０００９】
一対のレールには、その長手方向に亘って搬送体が各レールの対向する側に取り付けられている。そして、この搬送体と巻取りリールに取り付けられた係合部位が係合することによって、巻取りリールはレールの長手方向へ移動可能に制御される。この搬送体は、一対のレールの長手方向に亘って複数個に分割して設置され、巻取りリールに取り付けられた係合部位に係合して、巻取りリールをレールの長手方向へ移動可能に搬送制御される。
【００１０】
この搬送体は一対のレールの長手方向に亘って複数個巻掛けされた無端帯とすることができる。また前後に隣接する無端帯間には巻取りリールをその軸部に当接して各無端帯の間隔内を移動させる移動体が配設され、巻取りリールを次位の無端帯へ移動可能としている。この移動体は、各無端帯間の間隔内に位置して無端帯の搬送方向と直交する方向に任意間隔を置いて左右に一対設置された牽引具として構成することが可能であり、この牽引具に取り付けられた移動フックが前記一対の巻取りリールの軸部に介在して次位の無端帯の始端へ巻取りリールを移動させる。
【００１１】
また、移動体は移動コンベヤとすることも可能であり、この移動コンベヤに取り付けられた位置決め体が前記一対の巻取りリールの軸部に当接して移動コンベヤの回動により次位の無端帯の始端へ巻取りリールを移動させるものである。さらに、移動体を往復移動機構とすることも可能であり、この場合、往復移動機構に取り付けられた位置決め体が前記一対の巻取りリールの軸部に当接して往復移動機構の往復動により次位の無端帯の始端へ巻取りリールを移動させる。
【００１２】
さらには、移動体を支持棒として、この支持棒の基端を枢支点として旋回させ、その先端を前記一対の巻取りリールの軸部に当接して支持棒の旋回動により次位の無端帯の始端へ巻取りリールを移動させることも可能である。
【００１３】
またこの搬送体は、好適には、レールの長手方向に亘って複数個が設置され、巻取りリールに取り付けられた複数の係合部位のいずれかに係合して、リールに略直交する方向、すなわちレールと略平行に巻掛けされた複数列のチェーンコンベヤ、ベルトコンベヤ等の無端帯とできる。この係合部位は、例えば、巻取りリールのリール軸にその軸方向に或る間隔で取り付けられたギヤであり、無端帯とギヤとの係合によって巻取りリールをレールの長手方向へ移動させ、ベニヤ単板巻戻し位置へ搬送し、及び／又は貯留する。
【００１４】
このようにして、一対のレール上を移動方向に隣接する巻取りリール同士の間隔を、巻取りリールに巻き付けられた巻玉の外周部分が相互に接触している状態に制御することが可能となる。
【００１５】
また、上記課題を解決するために、本発明の巻取りリールの搬送制御装置は、巻取りリールと、この巻取りリールの両端に位置するベアリングが乗せられる一対のレールと、この一対のレールの長手方向に亘って設置された搬送体と、この搬送体に係合して前記巻取りリールを前記レールの長手方向へ移動可能とする巻取りリール係合部とを備え、前記レールの長手方向に亘って前記巻取りリールを任意の位置に移動させることを前提とする。
【００１６】
一対のレールは、ベニヤ単板の巻取り位置とベニヤ単板の巻き戻し位置との間に左右一対にほぼ平行に且つほぼ水平状態に配置されている。そして、ベニヤ単板が巻取られて巻玉化した巻取りリールをベニヤ単板巻き戻し位置へ搬送し、及び／又は貯留するものである。
【００１７】
また、一対のレールは、ベニヤ単板の巻取り位置とベニヤ単板の巻き戻し位置との間に左右一対に搬送方向に向かって若干下り勾配に配置することも可能である。この場合も、ベニヤ単板が巻取られて巻玉化した巻取りリールをベニヤ単板巻き戻し位置へ搬送し、及び／又は貯留することになる。
【００１８】
搬送体は一対のレールの長手方向に亘って複数個が設置され、これら前後に隣接する無端帯間には巻取りリールをその軸部に当接して各無端帯の間隔内を移動させる移動体が配設されている。この移動体は、各無端帯間の間隔内に位置して無端帯の搬送方向と直交する方向に任意間隔を置いて左右に一対設置された牽引具であり、この牽引具に取り付けられた移動フックとすることが可能である。
【００１９】
また、移動体は移動コンベヤとすることも可能であり、この移動コンベヤに取り付けられた位置決め体が前記一対の巻取りリールの軸部に当接して移動コンベヤの回動により次位の無端帯の始端へ巻取りリールを移動させることができる。また、移動体を往復移動機構としてこの往復移動機構に取り付けられた位置決め体を一対の巻取りリールの軸部に当接して往復移動機構の往復動により次位の無端帯の始端へ巻取りリールを移動させることもできる。さらには、移動体を支持棒としてこの支持棒の基端を枢支点として旋回させ、その先端を前記一対の巻取りリールの軸部に当接して支持棒の旋回動により次位の無端帯の始端へ巻取りリールを移動させることも可能である。
【００２０】
さらに、巻取りリールの軸方向に複数の係合部位が設けられ、搬送体は一対のレールの長手方向に亘って複数個設置されるとともに、複数の係合部位のいずれかに係合する軸方向に設置され、その設置された搬送体と該搬送体の位置に対応した係合部位が係合して巻取りリールをレールの長手方向へ移動可能な構成とすることもできる。
【００２１】
この無端帯は、例えば鎖車間に巻掛けされたチェーンコンベヤによって構成される。また、このチェーンコンベヤに係合する係合部は、前記巻取りリールの軸部に取り付けられたギヤとすることが可能であって、回動するチェーンコンベヤの駆動を従動することによって前記巻取りリールをレールの長手方向へ移動可能としている。そして、このチェーンコンベヤの始端部と終端部の近傍部位はその軌条走行位置より下方に位置している。このため、巻取りリールのギヤはチェーンコンベヤの始端部の近傍においてギヤと徐々に係合し始め、軌条走行位置間で前方へ移動され、終端部近傍においてその係合が解除されることにより、移動が停止される。
【００２２】
また，搬送体は、一対のレールの長手方向に亘って複数個分割され、且つ長手方向と交差する方向へ複数個設置された流体シリンダとすることも可能である。そして、そのピストンロッドのいずれかに巻取りリールに取り付けられた複数の係合部のいずれかが係合して、流体シリンダのシリンダ室への流体の給排によって巻取りリールをレールの長手方向へ移動させ、搬送制御可能としている。
【００２３】
【発明の実施の形態】
以下、本発明の実施の形態を、図面に示す実施例を参照して説明する。なお、既に説明した部品については同一番号を付して重複して説明しない。
図１において、前記巻取りリール５０のリール軸５１の中央部には、リール軸５１を回転中心としてベニヤ単板１をその幅方向に渡って巻取る巻取り面５２が形成されている。この巻取り面５２は円筒状であり、次のような形態で構成されている。すなわち、リール軸５１の軸芯方向には一定間隔を置いて円盤状の補強板５３が、リール軸５１に溶接等によってそれぞれ取り付けられている。これら補強板５３の外周には、この補強板５３の厚みの数倍以上の幅を有した平板５４を巻き付けて溶接等によって固着し、いわゆる鍔５５を構成している。これら鍔５５の外径は同径であり、それらの外周には、ベニヤ単板１を巻取るための巻取り面５２となる胴板５６がその曲率に沿って巻き付けられ、溶接等によって固着されている。
【００２４】
リール軸５１はその軸部の両端付近が小径に加工されている。図２に示すように、リール軸５１の両端部には、小球を環状に内蔵したベアリング１４が回転可能に取り付けられている。前記リール軸５１の一方の側のベアリング１４に近接する位置には、角状のガイド板１５が取り付けられている。そして、このガイド板１５の四角部にはガイドコロ１６がその外周部をガイド板１５より若干突出させた状態で回転可能に支持されている。一方、巻玉ストックエリア９の一対のレール１０、あるいはリールストックエリア１１の一対のレール１０の内側には、ベアリング１４が乗せられるとき、転動するベアリング１４が進行方向に対する左右の偏りを防止するガイドレール１７が敷設されている。なお、ガイド板１５が取り付けられた側のレール１０は、ガイドコロ１６が転動する分だけ、幅広に形成されることになる。
【００２５】
また、一対のレール１０は、ベニヤ単板１の巻取り位置とベニヤ単板１の巻き戻し位置との間に左右一対にほぼ平行に且つほぼ水平状態に配置されている。そして、ベニヤ単板１が巻取られて巻玉６化した巻取りリール５０をベニヤ単板巻き戻し位置へ搬送し、及び／又は貯留するものである。この場合、一対のレール１０は、ベニヤ単板１の巻取り位置とベニヤ単板１の巻き戻し位置との間に左右一対に搬送方向に向かって若干下り勾配に配置することも可能である。これら一対のレール１０には、図３に示すように、その長手方向に亘って搬送体２０が各レール１０の対向する側に取り付けられている。
【００２６】
この搬送体２０は、例えば、ベルトコンベヤ、チェーンコンベヤ等の無端帯２１によって構成される。チェーンコンベヤ２１は、レール１０の長手方向に亘って複数個設置されており、隣接するチェーンコンベヤ２１は、レール１０に対して巻取りリール５０の軸方向に向かって異なる距離に設置されるとともに、図８に示すように、一部が重なるように配置されている。例えば、チェーンコンベヤ２１を２列に千鳥状に配置する場合、巻取りリール５０のリール軸５１の軸方向に取り付けられるギヤ３１はこれら２列のチェーンコンベヤ２１の各軌条走行面に相当する位置に設けられている。複数列のチェーンコンベヤ２１は、このギヤ３１，３１のいずれかに係合して、巻取りリール５０をレール１０の長手方向へ移動させる。
【００２７】
具体的には、各レール１０の内側に搬送方向に一定の間隔を置いて支持軸２２を枢支し、これら支持軸２２に取り付けられた鎖車２３間にチエン２４を巻掛けする。この場合、このチェーンコンベヤ２１の始端部２５と終端部２６の近傍部位はその軌条走行位置２７より下方に位置している。すなわち、チェーンコンベヤ２１の始端と終端の近傍位置にガイド鎖車２８を各々枢軸して、始端部２５においては始端部２５の鎖車２９から軌条走行位置２７に向かって上り勾配となるように、また、終端部２６においては終端部２６の鎖車２９に向かって軌条走行位置２７から下り勾配となるように構成している。
【００２８】
一方、このチェーンコンベヤ２１に係合する係合部３０は、巻取りリール５０のリール軸部５１に取り付けられたギヤ３１とし、回動するチェーンコンベヤ２１の駆動を従動することによって前記巻取りリール５０をレール１０の長手方向へ移動可能としている。そして、上述したように、このチェーンコンベヤ２１の始端部２５と終端部２６の近傍部位はその軌条走行位置２７より下方に位置しているので、巻取りリール５０のギヤ３１はチェーンコンベヤ２１の始端部２５の近傍においてギヤ３１と徐々に係合し始め、軌条走行位置２７間で前方へ移動され、終端部２６近傍においてその係合が解除されることにより、移動が停止される。
【００２９】
すなわち、巻取りリール５０は少なくとも２列のチェーンコンベヤ２１のいずれかにギヤ３１が係合することによって前方へ移動される。そして、この２列を一組としたチェーンコンベヤ２１をレール１０の長手方向へ順次巻掛けすることによって、巻取りリール５０は巻玉ストックエリア９の始端位置（巻取り位置）から終端位置（巻戻し位置）まで各チェーンコンベヤ２１を乗り移りながら移動することになる。
【００３０】
そして、このチェーンコンベヤ２１の長さを巻取りリール５０に巻き付けられる巻玉６の最小径に設定することによって、巻玉ストックエリア９に搬送及び／又は貯留される巻玉６同士の隣接する間隔を密にすることが可能となる（図８参照）。また、チェーンコンベヤ２１のいずれかの支持軸２２に原動機３２の駆動を伝達するときにトルクリミッタ３３を介して接続する手段を採ることが有効である。これは、巻玉ストックエリア９に貯留されてレール１０上に待機している前方の巻取りリール５０に巻き付けられた巻玉６と、移動途上の巻取りリール５０の巻玉６の外径が当接した場合、原動機３２の駆動を停止させなくても、チェーンコンベヤ２１はトルクリミッタ３３を介して原動機３２の駆動を常時受動しているので、過度の負荷は回避できることになる。このようにして、一対のレール１０上を移動方向に隣接する巻取りリール５０同士の間隔を、巻取りリール５０に巻き付けられた巻玉６の外周部分が相互に接触している状態に制御することが可能となる。
【００３１】
また，搬送体２１は、図４に示すように一対のレール１０の長手方向に亘って複数個分割され、且つ長手方向と交差する方向へ複数個設置された流体シリンダ３４とすることも可能である。そして、そのピストンロッド３５のいずれかに巻取りリール５０に取り付けられた複数の係合部３０のいずれかが係合して、流体シリンダ３４のシリンダ室への流体の給排によって巻取りリール５０をレール１０の長手方向へ移動させ、搬送制御可能としている。
【００３２】
また、ベアリング１４はレール１０上を転動するとき、進行方向に対しての左右への偏りをガイドレール１７（図２参照）によって防止されながら前進する。このとき、リール軸５１の一方側に取り付けられたガイド板１５の四角部に位置する４個のガイドコロ１６のうち、進行方向に対して前後に離れた状態に位置する２個のガイドコロ１６が、レール１０上を転動することなる。このため、ガイド板１５の反転が阻止され、巻取りリール５０自体の回転を防止している。
【００３３】
なお、上述において、チェーンコンベヤ２１はリール軸５１の軸方向に２列設置した場合を説明しているが、これを単列として巻取りリール５０を移動制御することも可能である。すなわち、チェーンコンベヤ２１は一対のレール１０の長手方向に亘って任意間隔を置いて複数個巻掛け設置して構成する。そして、これら前後に隣接するチェーンコンベヤ２１間には巻取りリール５０のリール軸５１に当接して隣接する次位のチェーンコンベヤ２１の始端へ移動させる移動体６０が配設される。
【００３４】
この移動体６０は、図９に示すように、各チェーンコンベヤ２１間の間隔内に位置してチェーンコンベヤ２１の搬送方向と直交する方向に任意間隔を置いて左右に一対設置された牽引具６１であり、この牽引具６１に取り付けられた移動フックが前記一対の巻取りリール５０のリール軸部５１に介在して次位のチェーンコンベヤ２１の始端へ巻取りリール５０を移動させることになる。すなわち、この牽引具６１は前位のチェーンコンベヤ２１の軌条走行位置２７の終端部２６を移動開始位置Ａとし、後位のチェーンコンベヤ２１の軌条走行位置２７の始端部２５を移動完了位置Ｂとして巻取りリール２１を移動可能としている。
【００３５】
具体的には、一対のレール１０の内側上部に前記移動開始位置Ａと移動完了位置Ｂとの間を水平移動用の流体シリンダ６２によって枠体６３を水平方向へ移動可能に取り付ける。そしてこの枠体６３に昇降用の流体シリンダ６４を取り付けてそのロッド６５の先端にフック状の牽引具６１を取り付ける。これによれば、前位のチェーンコンベヤ２１によって巻取りリール５０が搬送されて軌条走行位置２７の終端部２６に至るとき、巻取りリール５０の両端のリール軸部５１を牽引具６１のフック状部分が引っかける。次いで昇降用の流体シリンダ６４を作動させて牽引具６１を上昇させるとともに、水平移動用の流体シリンダ６２によって枠体６３を搬送方向の前方へ移動させる。そして牽引具６１を下降させることによって巻取りリール５０を移動完了位置Ｂへ至らせ、次位のチェーンコンベヤ２１の軌条走行面２７の始端部２５へ位置させものである。
【００３６】
また、巻取りリール２１を移動開始位置Ａから移動完了位置Ｂまで移動可能とするには、上記のように左右一対の牽引具６１によって移動させる形態の他、以下の形態とすることも可能である。すなわち、前位と次位のチェーンコンベヤ２１の長手方向の間隔内に、移動コンベヤ７０を一対のレール１０の内側にそれぞれ回動可能に巻掛けする。そして、この移動コンベヤ７０の走行軌条面２７に位置決め体７１を少なくとも１個取り付ける。例えば、移動コンベヤ７０をチェーンコンベヤ２１とすれば、チェーンコンベヤ２１で構成するチェンリンクにアタチッメントを介して位置決め体７１を取り付け、この位置決め体７１によって巻取りリール５０のリール軸部５１に当接させるものである。
【００３７】
これによれば、前位のチェーンコンベヤ２１によって巻取りリール５０が搬送されて軌条走行位置２７の終端部２６に至るとき、移動コンベヤ７０を回動させて退避位置にあった位置決め体７１を移動コンベヤ７０の上方走行面へ至らせる。すなわち、位置決め体７１はチェーンコンベヤ２１の搬送面下より上方に突出して巻取りリール５０の両端のリール軸部５１に当接する（図１０ａ、図１１ａ参照）。移動コンベヤ７０の継続回動によって巻取りリール５０はそのリール軸部５１の両端を押動することになり（図１０ｂ、図１１ｂ参照）、巻取りリール５０はその両端部のベアリング１４がレール１０上を転動しながら、前位のチェーンコンベヤ２１の軌条走行面２７の終端部２６から次位のチェーンコンベヤ２１の軌条走行面２７の始端部２５へ移動される（図１０ｃ、図１１ｃ参照）。
【００３８】
また、巻取りリール５０を移動開始位置Ａから移動完了位置Ｂまで移動させるには、この移動コンベヤ７０に代替して搬送方向と直交する方向に任意間隔を置いて左右に一対の往復移動機構８０を搬送方向へ上り勾配に設置することによっても可能である。例えば、図１２に示すように、搬送方向に向かって上り勾配となるロッドレス流体シリンダ８１を設置し、位置決め体７１はこのロッドレス流体シリンダ８１に取り付けられている。そして位置決め体７１は移動開始位置Ａにおいて搬送面より突出して巻取りリール５０のリール軸部５１の両端に当接し、移動完了位置Ｂまで巻取りリール５０を押動することになる。巻取りリール５０はその両端部のベアリング１４がレール１０上を転動しながら、前位のチェーンコンベヤ２１の軌条走行面２７の終端部２６から次位のチェーンコンベヤ２１の軌条走行面２７の始端部２５へ移動される。
【００３９】
また、往復移動機構８０は以下のように構成することも可能である。図１３に示すように、チェーンコンベヤ２１の下方に位置決め体７１を移動開始位置Ａから移動完了位置Ｂまで移動可能とすることができる。すなわち、チェーンコンベヤ２１の搬送方向と直交する方向に任意間隔を置いて左右に一対に設置された複数個のピニオンギヤ８２に歯合されるラックギヤ８３の往復移動面を搬送方向に向かって上方傾斜させ、このラックギヤ８３の上面に位置決め体７１を取り付けている。そして、ビニオンギヤ８２を正逆転させることによってラックギヤ８３を移動開始位置Ａと移動完了位置Ｂとの間で往復移動させるものである。このとき、位置決め体７１は移動開始位置Ａにおいてチェーンコンベヤ２１の搬送面から突出して巻取りリール５０のリール軸部５１の両端に当接し、移動完了位置Ｂまで巻取りリール５０を押動することになる。巻取りリール５０はその両端部のベアリング１４がレール１０上を転動しながら、前位のチェーンコンベヤ２１の軌条走行面２７の終端部２６から次位のチェーンコンベヤ２１の軌条走行面２７の始端部２５へ移動される。そして、位置決め体７１はビニオンギヤ８２の逆転動によってラックギヤ８３を待機位置まで復帰させ、前位のチェーンコンベヤ２１の搬送面下に没入して次回の作動に待機する。
【００４０】
図１４に示すように、チェーンコンベヤ２１の下方に軸受された旋回軸８４を支点としてその先端を往復旋回可能として、位置決め体７１を移動開始位置Ａから移動完了位置Ｂまで移動可能とする場合もある。すなわち、チェーンコンベヤ２１の搬送方向と直交する方向に任意間隔を置いて左右に一対の旋回棒８５を旋回軸８４に取り付け、この旋回棒８５の先端に位置決め体７１を取り付けるものである。そして、旋回軸８４を所定角度内で旋回させることにより、位置決め体７１を移動開始位置Ａと移動完了位置Ｂとの間で往復移動させるものである。このとき、位置決め体７１は移動開始位置Ａにおいてチェーンコンベヤ２１の搬送面から突出して巻取りリール５０のリール軸部５１の両端に当接し、移動完了位置Ｂまで巻取りリール５０を押動することになる。巻取りリール５０はその両端部のベアリング１４がレール１０上を転動しながら、前位のチェーンコンベヤ２１の軌条走行面２７の終端部２６から次位のチェーンコンベヤ２１の軌条走行面２７の始端部２５へ移動される。そして、位置決め体７１は旋回軸８４の復帰回動によって前位のチェーンコンベヤ２１の搬送面下に没入して次回の作動に待機する。
【００４１】
なお、湿潤状態のベニヤ単板１であれば、従来からの巻取りに使用されている直径１６５mmの巻取りリール５を、そのまま使用することができる。しかしながら、この直径１６５mmの巻取りリールに乾燥後のベニヤ単板１を巻き付けると、その細い直径になじまず、繊維と平行する部分からの割れが発生しやすくなり、巻取りリール５０自体に巻き付けることが不可能となることが多かった。特に、乾燥後に発生した、割れ目、切れ目等がベニヤ単板１に存在すると、当該部分から裂断することになる。本発明者等は実験による知見にて、乾燥後のベニヤ単板１を巻取る巻取りリール５０の直径を３００mm以上として求め、一方、巻取られるベニヤ単板１の厚みに応じた曲率となる直径を、巻取りリール５０の直径をＤ（ｍｍ）、巻取られるベニヤ単板１の厚みＴ（ｍｍ）とすると、
Ｄ／Ｔ≧８５、Ｄ≧３００、
を満たすことにより、乾燥後のベニヤ単板を良好に巻取ることができる。例えばベニヤ単板１の厚みが２mmであれば、上記算式より、巻取りリール５０の直径Ｄは１７０mmに設定されるのであるが、この数値が３００mm未満であるので、巻取りリール５０の直径は３００mm以上となる。尚、上記実施例においては巻取りリール５０の直径を４５０mmとし、乾燥後のベニヤ単板１を巻取り、良好な結果を得ている。
【００４２】

BACKGROUND OF THE INVENTION
The present invention relates to a wet veneer veneer cut by a veneer lace, or a take-up reel conveyance control method and apparatus for winding the wet veneer veneer by drying the wet veneer veneer with a veneer dryer. It is about.
[0002]
[Prior art]
Conventionally, a wet veneer veneer 1 cut by a veneer lace is transported on a carry-in conveyor 2 as shown in FIG. 7, and is installed at an appropriate distance from a pulley 3 at its end. The winding ball 6 wound and wound by the winding reel 5 that press-rotates with the roll 4 is moved up in the reel column 8 via the lifting device 7, and is placed on the pair of rails 10 in the winding ball stock area 9. It is transferred to. The pair of rails 10 are laid as a slight downward gradient with respect to the traveling direction (rewinding position). Further, the veneer single plate 1 is rewound at the rewinding position, and the take-up reel 5 that has become empty is transferred to a pair of rails 10 in the reel stock area 11. The pair of rails 10 are laid as a slight downward gradient with respect to the traveling direction (winding position), and when the empty winding reel 5 reaches the winding position, the pair of rails 10 is lowered onto the side drive roll 4 and newly added. Winding has started. Also, the veneer single plate 1 dried by the veneer dryer is wound up by the take-up reel 5 in substantially the same manner as described above, and moves up on the reel column 8 to be transferred onto the pair of rails 10 in the roll ball stock area 9. Is done.
[0003]
The take-up reel 5, which is wound into a wet veneer veneer 1 and turned into a roll 6, is placed on the pair of rails 10 in the roll stock area 9 until it reaches the rewind position installed on the entry side of the veneer dryer. Are transferred in a rolling state with a downward slope. In addition, the take-up reel 5 on which the dried veneer veneer 1 is wound up, for example, rolls down on the pair of rails 10 with a downward gradient until reaching the rewind position installed in the mechanism process. It will be transferred in a moving state.

[Problems to be solved by the invention]
The take-up reel 5 that rolls on the rail 10 in the reel stock area 9 or on the rail 10 in the reel stock area 11 with a downward gradient is of course in the rewind position or the take-up position arranged at the end. The stopper is actuated to stop the take-up reel 5 at an appropriate position on the way of transfer. The take-up reel 5 rolls on the pair of rails 10 with an inertial force. In this state, the take-up reel 5 collides with the upper portion of the stopper waiting at the raised position protruding from the conveyance surface, and stops. The device constituting the stopper and / or the take-up reel 5 is damaged by the impact load.
[0005]
Further, when the take-up reel 5 rolls on the pair of rails 10, the take-up reel 5 may be displaced in any direction toward the traveling direction and meandered and conveyed. When this displacement state becomes significant, the bearing portion (not shown) of the take-up reel 5 that rolls on the rail 10 stops against either one of both wall portions that regulate the rail interval of the rail 10, The rolling state stops in that state. Each time this stop state occurs, the worker reaches the rail 10 in the reel stock area 9 and releases the stop state by human work. For this reason, not only workability | operativity falls, but the danger by an aerial work will accompany a worker. Furthermore, the rail 10 and / or the bearing 14 portion of the take-up reel 5 is damaged, and the problem is spread to safety management.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to examples shown in the drawings. The parts already described are assigned the same numbers and will not be described again.
In FIG. 1, a winding surface 52 is formed at the center of the reel shaft 51 of the take-up reel 50 to wind up the veneer single plate 1 in the width direction with the reel shaft 51 as a rotation center. The winding surface 52 has a cylindrical shape and is configured as follows. That is, disk-shaped reinforcing plates 53 are attached to the reel shaft 51 by welding or the like at regular intervals in the axial direction of the reel shaft 51. A flat plate 54 having a width several times the thickness of the reinforcing plate 53 is wound around the outer periphery of the reinforcing plate 53 and fixed by welding or the like to form a so-called flange 55. The outer diameters of these flanges 55 are the same, and a body plate 56 serving as a winding surface 52 for winding the veneer veneer 1 is wound around the outer periphery thereof along the curvature thereof and fixed by welding or the like. ing.
[0024]
The reel shaft 51 is processed to have a small diameter near both ends of the shaft portion. As shown in FIG. 2, bearings 14 in which small spheres are annularly incorporated are rotatably attached to both ends of the reel shaft 51. A square guide plate 15 is attached at a position close to the bearing 14 on one side of the reel shaft 51. A guide roller 16 is rotatably supported on the square portion of the guide plate 15 with its outer peripheral portion slightly protruding from the guide plate 15. On the other hand, when the bearing 14 is placed inside the pair of rails 10 of the reel stock area 9 or the pair of rails 10 of the reel stock area 11, the rolling bearing 14 prevents left-right bias with respect to the traveling direction. A guide rail 17 is laid. The rail 10 on the side on which the guide plate 15 is attached is formed to be wide enough for the guide roller 16 to roll.
[0025]
Further, the pair of rails 10 are disposed in a substantially horizontal state in a pair of left and right between the winding position of the veneer single plate 1 and the unwinding position of the veneer single plate 1. Then, the take-up reel 50 in which the veneer single plate 1 is wound to form a ball 6 is conveyed to a veneer single plate rewind position and / or stored. In this case, the pair of rails 10 may be disposed in a slightly downward slope toward the conveying direction in a pair of left and right between the winding position of the veneer single plate 1 and the unwinding position of the veneer single plate 1. As shown in FIG. 3, the pair of rails 10 has a transport body 20 attached to the opposite side of each rail 10 in the longitudinal direction.
[0026]
The carrier 20 is constituted by an endless belt 21 such as a belt conveyor or a chain conveyor. A plurality of chain conveyors 21 are installed in the longitudinal direction of the rail 10, and adjacent chain conveyors 21 are installed at different distances with respect to the rail 10 in the axial direction of the take-up reel 50, As shown in FIG. 8, it arrange | positions so that a part may overlap. For example, when the chain conveyors 21 are arranged in a zigzag pattern in two rows, the gear 31 attached in the axial direction of the reel shaft 51 of the take-up reel 50 is located at a position corresponding to each rail running surface of the two rows of chain conveyors 21. Is provided. The plurality of rows of chain conveyors 21 are engaged with either of the gears 31 and 31 to move the take-up reel 50 in the longitudinal direction of the rail 10.
[0027]
Specifically, a support shaft 22 is pivotally supported inside each rail 10 at a certain interval in the transport direction, and a chain 24 is wound around a chain wheel 23 attached to the support shaft 22. In this case, the vicinity of the starting end portion 25 and the terminal end portion 26 of the chain conveyor 21 is located below the rail travel position 27. That is, the guide chain wheels 28 are pivoted at positions near the start and end of the chain conveyor 21, and the start end 25 has an upward slope from the chain 29 of the start end 25 toward the rail travel position 27. Further, the end portion 26 is configured to have a downward slope from the rail travel position 27 toward the chain wheel 29 of the end portion 26.
[0028]
On the other hand, the engaging portion 30 that engages with the chain conveyor 21 is a gear 31 attached to the reel shaft portion 51 of the take-up reel 50, and the take-up reel is driven by driving the rotating chain conveyor 21. 50 is movable in the longitudinal direction of the rail 10. As described above, since the vicinity of the start end 25 and the end end 26 of the chain conveyor 21 is located below the rail travel position 27, the gear 31 of the take-up reel 50 is connected to the start end of the chain conveyor 21. In the vicinity of the portion 25, the gear 31 starts to gradually engage, moved forward between the rail travel positions 27, and the engagement is released in the vicinity of the terminal portion 26, whereby the movement is stopped.
[0029]
That is, the take-up reel 50 is moved forward when the gear 31 is engaged with one of the chain conveyors 21 in at least two rows. The take-up reel 50 is sequentially wound in the longitudinal direction of the rail 10 by setting the chain conveyor 21 as a set of these two rows, whereby the take-up reel 50 is moved from the start position (winding position) to the end position (winding position). Each chain conveyor 21 is moved to the return position).
[0030]
Then, by setting the length of the chain conveyor 21 to the minimum diameter of the winding balls 6 wound around the take-up reel 50, the adjacent intervals between the winding balls 6 conveyed and / or stored in the winding ball stock area 9 Can be made dense (see FIG. 8). Further, it is effective to adopt a means for connecting via a torque limiter 33 when transmitting the drive of the prime mover 32 to any one of the support shafts 22 of the chain conveyor 21. This is because the outer diameter of the winding ball 6 wound around the front winding reel 50 stored in the winding ball stock area 9 and waiting on the rail 10 and the winding ball 6 of the winding reel 50 on the move are In the case of contact, even if the driving of the prime mover 32 is not stopped, the chain conveyor 21 always passively drives the prime mover 32 via the torque limiter 33, so that an excessive load can be avoided. In this manner, the interval between the winding reels 50 adjacent to each other in the moving direction on the pair of rails 10 is controlled so that the outer peripheral portions of the winding balls 6 wound around the winding reel 50 are in contact with each other. It becomes possible.
[0031]
Further, as shown in FIG. 4, the transport body 21 can be divided into a plurality of fluid cylinders 34 that are divided in the longitudinal direction of the pair of rails 10 and installed in a direction intersecting the longitudinal direction. is there. One of the plurality of engaging portions 30 attached to the take-up reel 50 is engaged with one of the piston rods 35, and the take-up reel 50 is supplied and discharged by supplying and discharging fluid to and from the cylinder chamber of the fluid cylinder 34. Is moved in the longitudinal direction of the rail 10 to enable conveyance control.
[0032]
Further, when the bearing 14 rolls on the rail 10, the bearing 14 moves forward while being prevented by the guide rail 17 (see FIG. 2) from being biased left and right with respect to the traveling direction. At this time, of the four guide rollers 16 positioned at the square portion of the guide plate 15 attached to one side of the reel shaft 51, the two guide rollers 16 positioned in the front-rear direction with respect to the traveling direction. However, it rolls on the rail 10. For this reason, inversion of the guide plate 15 is prevented, and the take-up reel 50 itself is prevented from rotating.
[0033]
In the above description, the case where the chain conveyor 21 is installed in two rows in the axial direction of the reel shaft 51 is described. However, it is also possible to control the movement of the take-up reel 50 as a single row. In other words, a plurality of chain conveyors 21 are installed around the pair of rails 10 at an arbitrary interval in the longitudinal direction. Between the front and rear adjacent chain conveyors 21, a moving body 60 is disposed that contacts the reel shaft 51 of the take-up reel 50 and moves to the start end of the next adjacent chain conveyor 21.
[0034]
As shown in FIG. 9, the moving body 60 is located within the interval between the chain conveyors 21 and is provided with a pair of traction tools 61 arranged at right and left at an arbitrary interval in a direction orthogonal to the conveying direction of the chain conveyor 21. The moving hook attached to the traction tool 61 is interposed in the reel shaft portion 51 of the pair of take-up reels 50 and moves the take-up reel 50 to the starting end of the next chain conveyor 21. That is, the traction tool 61 has the end portion 26 of the rail travel position 27 of the front chain conveyor 21 as the movement start position A and the start end portion 25 of the rail travel position 27 of the rear chain conveyor 21 as the movement completion position B. The take-up reel 21 is movable.
[0035]
Specifically, the frame 63 is attached to the inner upper part of the pair of rails 10 so as to be movable in the horizontal direction between the movement start position A and the movement completion position B by a fluid cylinder 62 for horizontal movement. Then, a lifting / lowering fluid cylinder 64 is attached to the frame 63, and a hook-like traction tool 61 is attached to the tip of the rod 65. According to this, when the take-up reel 50 is conveyed by the front chain conveyor 21 and reaches the end portion 26 of the rail travel position 27, the reel shaft portions 51 at both ends of the take-up reel 50 are hooked to the traction tool 61. The part hooks. Next, the lifting / lowering fluid cylinder 64 is actuated to raise the traction tool 61, and the horizontal movement fluid cylinder 62 moves the frame 63 forward in the transport direction. Then, by lowering the traction tool 61, the take-up reel 50 is brought to the movement completion position B and is positioned at the start end 25 of the rail running surface 27 of the next chain conveyor 21.
[0036]
Further, in order to make the take-up reel 21 movable from the movement start position A to the movement completion position B, it is possible to adopt the following form in addition to the form in which it is moved by the pair of left and right traction tools 61 as described above. is there. That is, the moving conveyor 70 is wound around the inner sides of the pair of rails 10 so as to be rotatable within the distance between the front and the next chain conveyors 21 in the longitudinal direction. Then, at least one positioning body 71 is attached to the running rail surface 27 of the moving conveyor 70. For example, if the moving conveyor 70 is the chain conveyor 21, a positioning body 71 is attached to the chain link formed by the chain conveyor 21 via an attachment, and the positioning body 71 is brought into contact with the reel shaft portion 51 of the take-up reel 50. Is.
[0037]
According to this, when the take-up reel 50 is conveyed by the front chain conveyor 21 and reaches the end portion 26 of the rail travel position 27, the movable conveyor 70 is rotated to move the positioning body 71 at the retracted position. It leads to the upper running surface of the conveyor 70. That is, the positioning body 71 protrudes upward from below the conveying surface of the chain conveyor 21 and comes into contact with the reel shaft portions 51 at both ends of the take-up reel 50 (see FIGS. 10a and 11a). The take-up reel 50 pushes both ends of the reel shaft 51 by the continuous rotation of the moving conveyor 70 (see FIGS. 10b and 11b). While rolling up, it is moved from the end portion 26 of the rail running surface 27 of the front chain conveyor 21 to the start end portion 25 of the rail running surface 27 of the next chain conveyor 21 (see FIGS. 10c and 11c). .
[0038]
Further, in order to move the take-up reel 50 from the movement start position A to the movement completion position B, a pair of reciprocating mechanisms 80 on the left and right sides are arranged at an arbitrary interval in a direction orthogonal to the conveying direction instead of the moving conveyor 70. It is also possible to install the incline in the transport direction. For example, as shown in FIG. 12, a rodless fluid cylinder 81 that is inclined upward in the transport direction is installed, and the positioning body 71 is attached to the rodless fluid cylinder 81. Then, the positioning body 71 protrudes from the conveyance surface at the movement start position A, contacts both ends of the reel shaft portion 51 of the take-up reel 50, and pushes the take-up reel 50 to the movement completion position B. The winding reel 50 has the bearings 14 at both ends rolling on the rail 10, and the leading end of the rail running surface 27 of the next chain conveyor 21 from the terminal portion 26 of the rail running surface 27 of the front chain conveyor 21. Moved to section 25.
[0039]
Further, the reciprocating mechanism 80 can also be configured as follows. As shown in FIG. 13, the positioning body 71 can be moved from the movement start position A to the movement completion position B below the chain conveyor 21. That is, the reciprocating surface of the rack gear 83 meshed with a plurality of pinion gears 82 installed on the left and right sides at an arbitrary interval in a direction orthogonal to the transport direction of the chain conveyor 21 is inclined upward in the transport direction. A positioning body 71 is attached to the upper surface of the rack gear 83. The rack gear 83 is reciprocated between the movement start position A and the movement completion position B by rotating the binion gear 82 forward and backward. At this time, the positioning body 71 protrudes from the transport surface of the chain conveyor 21 at the movement start position A, contacts both ends of the reel shaft portion 51 of the take-up reel 50, and pushes the take-up reel 50 to the movement completion position B. become. The winding reel 50 has the bearings 14 at both ends rolling on the rail 10, and the leading end of the rail running surface 27 of the next chain conveyor 21 from the terminal portion 26 of the rail running surface 27 of the front chain conveyor 21. Moved to section 25. Then, the positioning body 71 returns the rack gear 83 to the standby position by the reverse rotation of the binion gear 82, immerses under the transport surface of the front chain conveyor 21, and waits for the next operation.
[0040]
As shown in FIG. 14, there is a case where the end of the turning shaft 84 supported below the chain conveyor 21 can be reciprocally turned and the positioning body 71 can be moved from the movement start position A to the movement completion position B. is there. That is, a pair of swivel rods 85 are attached to the swivel shaft 84 at an arbitrary interval in a direction orthogonal to the conveying direction of the chain conveyor 21, and the positioning body 71 is attached to the tip of the swivel rod 85.
