Description

【０００１】
【発明の属する技術分野】
本発明は、合板製造工程において、ベニヤ単板をその搬送途上において前端を規制したり、或いは２枚重ね状態のベニヤ単板の端縁を揃えて一旦ベニヤ単板堆積装置上へ堆積させるか、若しくはそのままベニヤ単板の仕組み工程へ搬送するベニヤ単板の端部規制方法及び装置に関するものである。
【０００２】
【従来の技術】
合板の製造工程においては、ベニヤ単板の繊維方向を平行として複数枚重ね合わせて平行合板（単板積層材）、或いはその繊維方向を上下に隣接するもの同士を互いに交差させて複数枚重ね合わせて合板としている。
【０００３】
これら平行合板、或いは合板（以下合板という）は、ベニヤドライヤによって乾燥されたベニヤ単板の上面及び／又は下面に接着剤を塗布して、この接着剤が塗布されたベニヤ単板の上下面にベニヤ単板を供給し、その後ホットプレスによって熱圧される。例えば、３層構造より成る合板であれば、表板、中板、裏板となる３種に分類されたベニヤ単板によって構成され、通常、接着剤塗布装置によってその上下面に接着剤が塗布された中板を、表板と裏板が１組に仕組まれた上に載置することになる。
【０００４】
従来より、接着剤がその上下両面に塗布された中板と１組の表板、裏板との貼り合わせ作業は、中板堆積装置上から接着剤塗布装置に中板を１枚宛供給する作業者と、接着剤塗布装置によって接着剤が塗布された中板を受け取るため、接着剤塗布装置に隣接して設置され、表板と裏板が複数組堆積された仕組み単板堆積装置の近傍に位置する２名の作業者と、この仕組み単板堆積装置上から１組の表板と裏板とを仮合板堆積装置上へ載置された中板上へ供給する２名の作業者によって行われている。
【０００５】
したがって、乾燥後のベニヤ単板は、表板と裏板とを一旦１組に仕組んだ後、人手を介して上下方向においてその端縁が揃えられた状態で仕組み単板堆積装置上に載置される。また、この人手による作業工程の自動化を図って、ベニヤドライヤで乾燥されたベニヤ単板を表板と裏板に選別し、これら表板と裏板とを貼り合わせ作業位置まで搬送する途上に、それぞれの搬送経路上の表板と裏板とをその経路上のいずれかの位置で２枚に重ね合わせている。この貼り合わせ位置までの各搬送経路上から表板、裏板のそれぞれのベニヤ単板を同一搬送経路上へ重ね合わせるとき、２枚１組のベニヤ単板をその上下方向における端縁を正確に位置合わせする必要がある。
【０００６】
【発明が解決しようとする課題】
しかしながら、木質系特有の性状に起因して、搬送経路上で上下方向に重ね合わされた２枚１組の各ベニヤ単板のそれぞれの端縁を位置合わせすることが困難であった。すなわち、上部のベニヤ単板を下部のベニヤ単板に対して物理的に押し付けながらそれぞれの端縁を位置合わせしようとしても、ベニヤ単板の表面に現出する逆目、毛羽立ち、節目等が各ベニヤ単板間の摺動抵抗となって正確に端縁を揃えることができなかった。また、ベニヤ単板の脆弱性に起因して、ベニヤ単板の後端を押動することによってその前端部を揃えることは、端部が座屈する原因ともなり、その規制が困難であった。
【０００７】
そこで、本発明は、ベニヤ単板をその搬送途上において前端を規制したり、或いは同一の搬送経路上に上下方向に重ね合わされた状態で搬送される２枚以上の複数枚のベニヤ単板を、その搬送経路上においてそれぞれの端縁を位置合わせするベニヤ単板の端部規制方法及び装置を提供するものである。
【０００８】
【課題を解決するための手段および発明の効果】
上記課題を解決するために、本発明のベニヤ単板の端部規制方法は、
ベニヤ単板を前方へ繰り出すと共に上下方向への動きも駆動体に付与することによってベニヤ単板を自重落下させ、これら繰り出し方向と上下方向の動きを繰り返しながら、停止体によってベニヤ単板の繰り出しが停止されるときにベニヤ単板の前端を規制することを特徴とする
【０００９】
また、本発明のベニヤ単板の端部規制方法は、
少なくとも２枚以上に重ね合わされたベニヤ単板を前方へ繰り出しながら、その重ね合ったベニヤ単板に対して上下方向への動きも駆動体に付与することにより、上部のベニヤ単板とその下部のベニヤ単板の間隔内に層間分離を生じさせて下部のベニヤ単板が前方へ繰り出されるとき、下部のベニヤ単板上へ上部のベニヤ単板を自重落下させ、これら繰り出し方向と上下方向の動きを繰り返すことによって、停止体によってベニヤ単板の繰り出しが停止されるときに各ベニヤ単板の前端を規制することを特徴とする。
【００１０】
前記停止体は、前記駆動体の前方に位置してこの駆動体とは別個に設置されている。駆動体が停止体に向けてある振幅で振動してベニヤ単板を前方へ繰り出すときに、ベニヤ単板は駆動体上から一旦離れて繰り出し方向と上下方向とが合成する方向へ移動する。そして、ベニヤ単板の前端部分が停止体によって停止されるとき、停止体との停止位置から駆動体上へ自由落下する。これを繰り返すことによってベニヤ単板の前端部分が停止体位置へ規制されることになる。
【００１１】
また、前記停止体は、前記駆動体と一体的に設置することも可能である。この場合においても、駆動体が停止体に向けてある振幅で振動してベニヤ単板を前方へ繰り出すときに、ベニヤ単板は駆動体上から一旦離れて繰り出し方向と上下方向とが合成する方向へ移動する。そして、ベニヤ単板の前端部分が停止体によって停止されるとき、停止体との停止位置から駆動体上へ自由落下するのであるが、停止体も駆動体と共に振幅の後退限まで移動する。したがって、ベニヤ単板は停止体と当接状態も保って自由落下することになる。
【００１２】
前記停止体はベニヤ単板の前端部の全面に設置しても良いが、好適にはベニヤ単板の繰り出し方向と交差する方向に複数個、例えば搬送方向と交差する方向に任意間隔を置いて一対設置される。そして、駆動体によって前方へ搬送されるベニヤ単板の前端部分が任意時間だけ停止体によって停止される。この任意時間、ベニヤ単板には、前進方向の水平分力と上下方向の垂直分力が付与される。仮に、搬送途上のベニヤ単板が搬送方向の交差する方向が左右いずれかに偏倚していた場合、上述のように駆動体を任意時間振動させることによって、先に到達する前端部分が停止体によって停止される間に他方の前端部分が前方へ繰り出されることによって規制される。
【００１３】
また、２枚以上のベニヤ単板が重ね合った状態で搬送されている場合、駆動体によって前方へ搬送される重ね合ったベニヤ単板の各前端部分が任意時間だけ停止体によって停止される。この任意時間、重ね合ったベニヤ単板には、前進方向の水平分力と上下方向の垂直分力が付与される。
【００１４】
したがって、駆動体によって上下方向の動きがベニヤ単板に付与されるとき、上下方向に重ね合ったベニヤ単板間には空隙が形成される。そして、下部のベニヤ単板には駆動体による前方への繰り出し力が付与されることになるが、停止体によってその繰り出しが規制される。一方、上部のベニヤ単板は一旦下部のベニヤ単板との摺動抵抗から解放されながら前方への繰り出し力を受け、その後自重によって下部のベニヤ単板上へ自由落下することになる。そして、この状態を任意時間だけ継続することによって繰り出し方向の前端縁が揃えられ、上下方向において位置合わせされる。
【００１５】
この駆動体に付与される振幅は、好適には５ないし５０ｍｍであり、さらに好適には、１０ないし３ｍｍに設定されている。そして、この停止体はベニヤ単板の搬送面に対して起伏可能とすることも可能である。このようにすれば、ベニヤ単板の前端部分が任意時間だけ停止体によって規制された後、搬送面下に倒伏させることによって、各前端部分が位置合わせされたベニヤ単板は、例えば上述したような貼り合わせ位置まで搬送され、以後の貼り合わせ工程の自動化を円滑に実施することが可能となる。
【００１６】
上記課題を解決するために、本発明のベニヤ単板の端部規制装置の構成は、
ベニヤ単板を前方へ繰り出しながら、上下方向への動きも付与する駆動体と、
前記ベニヤ単板の繰り出し方向に位置し、ベニヤ単板の繰り出し方向と交差する方向に複数個設置されてベニヤ単板の搬送面に対して起伏可能な停止体と、
を少なくとも備えたことを特徴とする。
【００１７】
また、上記課題を解決するために、本発明のベニヤ単板の端部規制装置の構成は、
少なくとも２枚以上に重ね合った状態のベニヤ単板を前方へ繰り出しながら、その重ね合ったベニヤ単板に対して上下方向への動きも付与する駆動体と、
前記ベニヤ単板の繰り出し方向に位置し、ベニヤ単板の繰り出し方向と交差する方向に複数個設置されてベニヤ単板の搬送面に対して起伏可能な停止体と、
を少なくとも備えたことを特徴とする。
【００１８】
前記駆動体はベニヤ単板の繰り出し方向に少なくとも一対設置されている。そして、この駆動体にある振幅で振動させてベニヤ単板に対して前方への繰り出しと上下方向へとが合成された方向への動きを付与する作動体を接続している。この作動体は、例えば、駆動体に枢支された連係具と偏心輪との偏心回転によって、ベニヤ単板に対して前方への繰り出しと上下方向への動きを付与するものである。
【００１９】
例えば、この駆動体には、架台上に繰り出し方向に相前後して支持バネを取り付けている。この支持バネは圧縮用のねじりコイルバネであって、この支持バネによって自由振動を許容された状態で繰り出し方向と平行に敷設された一対の軌条に、好適には高摩擦部材を取り付けて構成されている。この一対の軌条に取り付けられた取付具に、架台のほぼ中央部に位置する軸受に軸支した回転軸に連係具を介して連係させている。そして、この回転軸に偏心輪と回転伝達部材を取り付けて偏心回転させ、一対の軌条を偏心輪の回転数と偏心量によって定まる一定の振幅で振動させ、重ね合ったベニヤ単板に前進方向の水平分力と上下方向の垂直分力を付与している。
【００２０】
また、作動体をこの偏心輪の回転数と偏心量によって定まる一定の振幅で振動させる方式に代替して、駆動体に取り付けられた流体シリンダとピストンロッドによる伸縮動によって、ベニヤ単板に対して前方への繰り出しと上下方向とを合成した方向への動きを付与することも可能である。
【００２１】
さらに、駆動体に取り付けられたカム機構に伴う往復動によって、或いは駆動体に取り付けられた電磁石のＯＮ・ＯＦＦ制御によっても、ベニヤ単板に対して前方への繰り出しと上下方向とを合成した方向への動きを付与することも可能である。
【００２２】
前記停止体は、前記駆動体の前方に位置してこの駆動体とは別個に離隔して設置される。そして、駆動体が停止体に向けてある振幅で振動してベニヤ単板を前方へ繰り出すときにベニヤ単板の前端を停止体に停止させる。また、前記停止体は、前記駆動体と一体的に設置することも可能である。この場合、駆動体がある振幅で振動してベニヤ単板を前方へ繰り出すときに、この駆動体と一体的に振動する停止体にベニヤ単板の前端を停止させることになる。
【００２３】
また、前記各駆動体の繰り出し方向と交差する方向の間隔内には、好適には前記停止体が搬送面下へ倒伏したとき、ベニヤ単板を次工程へ搬送する少なくとも一対の搬送体を備えている。すなわち、前記一対の軌条間隔内には、次段工程へ上下方向の端縁が位置合わせされたベニヤ単板を搬送するため、前記停止体の上流位置から下流位置にかけて一対のベルト、或いはチエン等の無端状のコンベヤが設置されている。
【００２４】
そして、前者の軌条による駆動体においては、ベニヤ単板の繊維方向が繰り出し方向に対して交差する方向であっても、ベニヤ単板の前端部分が繰り出し方向に座屈することなく搬送できる。
【００２５】
【発明の実施の形態】
以下、本発明の実施例を添付図面に基づいて説明する。
図１及び図２に示すように、駆動体１は単一のベニヤ単板２、或いは上下方向に重ね合わされたベニヤ単板２，３を前方へ繰り出しながら、上下方向への動きを付与するように、ベニヤ単板２，３の繰り出し方向に少なくとも一対の軌条４，５が設置されている。すなわち、架台６上の繰り出し方向に相前後して、架台６に枢支された支持具７の他端を一対の軌条４，５の下部にそれぞれ枢支し、この支持具７に支持バネ８を取り付けている。
【００２６】
この支持バネ８は圧縮用ねじりコイルバネであり、架台６、軌条４，５、支持具７を常態において平行四辺形状に保持している。そして、ベニヤ単板２，３の繰り出し方向と平行に敷設された一対の軌条４，５は、この支持バネ８によって自由振動を許容された状態となっている。これら軌条４，５の上部にはゴム、織布等の高摩擦部材９を取り付けて、この高摩擦部材９の上面に２枚に重ね合わされたベニヤ単板２，３を載置している。
【００２７】
この一対の軌条４，５に繰り出し方向と上下方向とが合成する方向への動きを付与する作動体１０を取り付ける。この作動体１０とは、一対の軌条４，５に取り付けられた取付具１１に、架台６のほぼ中央部に位置する軸受に軸支した回転軸１２に連係具１３を介して連係させている。そして、この回転軸１２にベルト、チエン等の回転伝達部材１４を原動機１５に巻掛けして回転させ、この回転軸１２の両端部に取り付けられた偏心輪１６を偏心回転させる。このようにして、一対の軌条４，５を偏心輪１６の回転数と偏心量によって定まる一定の振幅で振動させ、単一のベニヤ単板２、或いは重ね合ったベニヤ単板２，３に前進方向の水平分力と上下方向の垂直分力を付与している。
【００２８】
また、前記駆動体１の下流にはベニヤ単板２，３の繰り出し方向と交差する方向に支軸１７が掛け渡され、この支軸１７に一定の間隔を置いて取り付けられた停止体１８が設置されている。この場合、停止体１８は、前記駆動体１の前方に位置してこの駆動体１とは別個に設置されている。そして、駆動体１が作動体１０、すなわち偏心輪１６の偏心回転によって停止体１８に向けてある振幅で振動して単一のベニヤ単板２、或いは重ね合ったベニヤ単板２，３を前方へ繰り出すときに、単一のベニヤ単板２、或いは重ね合ったベニヤ単板２，３は駆動体１上から一旦離れて繰り出し方向と上下方向とが合成する方向へ移動する。そして、単一のベニヤ単板２、或いは重ね合ったベニヤ単板２，３の前端部分が停止体１８によって停止されるとき、停止体１８との停止位置から駆動体１上へ自由落下する。これを繰り返すことによって単一のベニヤ単板２、或いは重ね合ったベニヤ単板２，３の前端部分が停止体位置へ規制されることになる。
【００２９】
また、前記停止体１８は、前記駆動体１と一体的に設置することも可能である。すなわち、図３に示すように、前記一対の軌条４，５間にブラケット２０を介して支軸１７を枢支して、この支軸１７に一定の間隔を置いて停止体１８を取り付け、駆動体１と停止体１８を一体的に作動させるものである。この場合においても、偏心輪１６の偏心回転によって停止体１８に向けてある振幅で振動して単一のベニヤ単板２、或いは重ね合ったベニヤ単板２，３を前方へ繰り出すときに、単一のベニヤ単板２、或いは重ね合ったベニヤ単板２，３は駆動体１上から一旦離れて繰り出し方向と上下方向とが合成する方向へ移動する。そして、単一のベニヤ単板２、或いは重ね合ったベニヤ単板２，３の前端部分が停止体１８によって停止されるとき、停止体１８との停止位置から駆動体１上へ自由落下するのであるが、停止体１８も駆動体１と共に振幅の後退限まで移動する。したがって、単一のベニヤ単板２、或いは重ね合ったベニヤ単板２，３は停止体１８と当接状態も保って自由落下することになる。
【００３０】
前記停止体１８はベニヤ単板２，３の前端部の全面に設置しても良いが、好適にはベニヤ単板２，３の繰り出し方向と交差する方向に複数個、例えば搬送方向と交差する方向に任意間隔を置いて一対設置される。そして、駆動体１によって前方へ搬送されるベニヤ単板２，３の前端部分が任意時間だけ停止体１８によって停止される。この任意時間、ベニヤ単板２，３には、前進方向の水平分力と上下方向の垂直分力が付与される。仮に、搬送途上の単一のベニヤ単板２が搬送方向の交差する方向が左右いずれかに偏倚していた場合（図４の実線に示すベニヤ単板参照）、上述のように駆動体１を任意時間振動させることによって、先に到達する前端部分が停止体１８によって停止される間に他方の前端部分が前方へ繰り出されることによって規制される（図４の二点鎖線参照）。
【００３１】
また、２枚以上のベニヤ単板２，３が重ね合った状態で搬送されている場合、駆動体１によって前方へ搬送される重ね合ったベニヤ単板２，３の各前端部分が任意時間だけ停止体１８によって停止される。この任意時間、重ね合ったベニヤ単板２，３には、前進方向の水平分力と上下方向の垂直分力が付与される。
【００３２】
この支軸１７は、例えば原動機１９等をおよそ９０度だけ正逆回転させることによって、ベニヤ単板２，３の搬送面に対して前記停止体１８を起伏可能としている。そして、前記各駆動体１の繰り出し方向と交差する方向の間隔内には、前記停止体１８が搬送面下へ倒伏したとき、ベニヤ単板２，３を次工程へ搬送する少なくとも一対の搬送体２１を備えている。
【００３３】
すなわち、前記一対の軌条４，５間隔内には、次段工程へ上下方向の端縁が位置合わせされたベニヤ単板２，３を搬送するため、前記停止体１８の上流位置から下流位置にかけて一対のベルト、或いはチエン等の無端状のコンベヤが設置されている。
【００３４】
したがって、回転軸１２が回転して偏心輪１６を介して一対の軌条４，５に一定の振幅を付与するとき、上下方向に重ね合ったベニヤ単板２，３は繰り出される（図５参照）。次いで、起立状態の停止体１８にその前端が到達すると、各前端部分が任意時間だけ停止体１８によって停止される（図６参照）。この任意時間、重ね合ったベニヤ単板２，３には、前進方向の水平分力と上下方向の垂直分力が付与される。そして、一対の軌条４，５によって上下方向の動きがベニヤ単板２，３に付与されるとき、上下方向に重ね合ったベニヤ単板２，３間には空隙が形成される（図７参照）。このとき、下部のベニヤ単板３には駆動体１による前方への繰り出し力が付与されることになるが、停止体１８によってその繰り出しが規制される。一方、上部のベニヤ単板２は一旦下部のベニヤ単板３との摺動抵抗から解放されながら前方への繰り出し力を受け、その後自重によって下部のベニヤ単板３上へ自由落下することになる。
【００３５】
この状態を任意時間だけ継続することによって繰り出し方向の前端縁が揃えられ、上下方向において位置合わせされる（図８参照）。次いで、停止体１８を搬送面下に倒伏させることによって、各前端部分が位置合わせされたベニヤ単板２，３は次段工程まで搬送される。
【００３６】
特に、駆動体１を一対の軌条４，５によって構成する場合には、ベニヤ単板２，３の繊維方向が繰り出し方向に対して交差する方向であっても、ベニヤ単板２，３の前端部分が繰り出し方向に座屈することなく搬送できる。また、後者の回転構造体による駆動体１においては、ベニヤ単板２，３の繊維方向が繰り出し方向と平行である場合においては有効な手段である。
【００３７】
また、作動体１０を上述のような偏心輪１６の回転数と偏心量によって定まる一定の振幅で振動させる方式に代替して、図９に示すように駆動体１に取り付けられた流体シリンダ２２とピストンロッド２３とすることも可能である。すなわち、この流体シリンダ２２の前後部シリンダ室へ流体を給排させることによってピストンロッド２３を伸縮動させて、単一のベニヤ単板２、上下方向に重ね合ったベニヤ単板２，３に対して前方への繰り出しと上下方向とを合成した方向への動きを付与することも可能である。
【００３８】
さらに、いずれも図示は省略するが、駆動体１に取り付けられたカム機構に伴う往復動によって、或いは駆動体１に取り付けられた電磁石のＯＮ・ＯＦＦ制御によっても、単一のベニヤ単板２、上下方向に重ね合ったベニヤ単板２，３に対して前方への繰り出しと上下方向とを合成した方向への動きを付与することも可能である。
【００３９】
本発明は、その根本的技術的思想を踏襲し、発明の効果を著しく損なわない限度において、前記の実施態様の一部を変更して実施でき、それらの変更態様も当然に本発明の技術的範囲に包含される。

BACKGROUND OF THE INVENTION
In the plywood manufacturing process, the front end of the veneer single plate is regulated in the course of conveying the plywood, or the edges of the two-layer veneer single plate are aligned and temporarily deposited on the veneer single plate deposition apparatus, Or it is related with the edge part regulation method and apparatus of a veneer veneer conveyed as it is to the mechanism process of a veneer veneer.
[0002]
[Prior art]
In the manufacturing process of plywood, multiple sheets of veneer veneer are overlapped with the fiber direction parallel to each other, and parallel plywood (single veneer laminate) or the fiber direction adjacent to each other is overlapped with each other. Plywood.
[0003]
These parallel plywoods or plywoods (hereinafter referred to as plywoods) are coated on the upper and lower surfaces of the veneer veneer coated with this adhesive by applying an adhesive to the upper and / or lower surface of the veneer veneer dried by the veneer dryer. A veneer veneer is supplied and then hot pressed by a hot press. For example, in the case of a plywood having a three-layer structure, it is constituted by veneer single plates classified into three types: a front plate, an intermediate plate, and a back plate, and an adhesive is usually applied to the upper and lower surfaces by an adhesive application device. The intermediate plate thus mounted is placed on the front plate and the back plate that are assembled into one set.
[0004]
Conventionally, in the pasting operation of the middle plate on which the adhesive is applied on both the upper and lower surfaces and a pair of front and back plates, one middle plate is supplied from the middle plate deposition device to the adhesive coating device. In order to receive the middle plate coated with adhesive by the operator and the adhesive applicator, it is installed adjacent to the adhesive applicator, and a structure in which multiple sets of front and back plates are deposited in the vicinity of the single plate deposition device And two workers who supply a pair of front and back plates onto the intermediate plate mounted on the temporary plywood deposition device from the mechanism single plate deposition device Has been done.
[0005]
Therefore, after drying the veneer veneer, the front plate and the back plate are once assembled and then placed on the structural veneer stacking device with the edges aligned in the vertical direction by hand. Is done. In addition, in order to automate the manual work process, the veneer single plate dried with the veneer dryer is sorted into a front plate and a back plate, and on the way to transport these front plate and back plate to the bonding work position, A front plate and a back plate on each conveyance path are superimposed on two sheets at any position on the path. When the veneer veneers on the front and back plates are overlapped on the same conveyance path from each conveyance path up to this bonding position, the edge in the vertical direction of each pair of veneer single sheets is accurately set. Need to align.
[0006]
[Problems to be solved by the invention]
However, due to the characteristics peculiar to the woody system, it is difficult to align the respective edges of each pair of veneer single plates that are superposed in the vertical direction on the transport path. That is, even if the upper veneer veneer is physically pressed against the lower veneer veneer and each edge is aligned, the reverse eye, fluff, knot, etc. appearing on the surface of the veneer veneer Due to the sliding resistance between the veneer veneers, the edges could not be aligned exactly. Further, due to the vulnerability of the veneer veneer, aligning the front end by pushing the rear end of the veneer veneer also causes the end to buckle, and its regulation is difficult.
[0007]
Therefore, the present invention regulates the front end of the veneer veneer during its conveyance, or two or more veneer veneers that are conveyed in the state of being vertically stacked on the same conveyance path, The present invention provides a veneer veneer edge regulating method and apparatus for aligning respective edges on the conveyance path.
[0008]
[Means for Solving the Problems and Effects of the Invention]
In order to solve the above problems, the method for regulating the end of the veneer veneer according to the present invention includes:
The veneer veneer is fed forward by moving the veneer veneer forward and moving the veneer veneer in the vertical direction, causing the veneer veneer to fall by its own weight. The front end of the veneer veneer is restricted when the veneer is stopped.
Moreover, the method for regulating the end of the veneer veneer of the present invention is as follows:
While feeding the veneer veneer stacked at least two or more forwards to the drive body, the upper veneer veneer and the lower veneer veneer When the lower plywood veneer is fed forward by causing interlayer separation within the veneer veneer spacing, the upper veneer veneer falls by its own weight onto the lower veneer veneer and moves in the feeding direction and the vertical direction. By repeating the above, when the feeding of the veneer veneer is stopped by the stop body, the front end of each veneer veneer is regulated.
[0010]
The stop body is located in front of the drive body and is installed separately from the drive body. When the drive body vibrates with a certain amplitude toward the stop body and feeds the veneer single plate forward, the veneer single plate is once separated from the drive body and moves in a direction in which the feed direction and the vertical direction are combined. And when the front-end part of a veneer veneer is stopped by a stop body, it falls freely on a drive body from the stop position with a stop body. By repeating this, the front end portion of the veneer veneer is restricted to the stop body position.
[0011]
Further, the stop body can be installed integrally with the drive body. Even in this case, when the drive body vibrates with a certain amplitude toward the stop body and the veneer veneer is fed forward, the veneer veneer is once separated from the drive body, and the feeding direction and the vertical direction are combined. Move to. When the front end portion of the veneer veneer is stopped by the stop body, it freely falls onto the drive body from the stop position with the stop body, but the stop body also moves to the retracting limit of the amplitude together with the drive body. Therefore, the veneer veneer falls freely while maintaining contact with the stop body.
[0012]
The stopping body may be installed on the entire front end portion of the veneer veneer, but preferably a plurality of the veneer veneer veneer in the direction intersecting the feeding direction of the veneer veneer, for example, at an arbitrary interval in the direction intersecting the transport direction. A pair is installed. And the front-end part of the veneer veneer conveyed ahead by the drive body is stopped by a stop body only for arbitrary time. For this arbitrary time, the horizontal component force in the forward direction and the vertical component force in the vertical direction are applied to the veneer single plate. If the veneer veneer on the way of conveyance is deviated to the left or right in the direction in which the conveyance direction intersects, the front end portion that reaches first is caused by the stop body by vibrating the drive body for an arbitrary time as described above. While being stopped, the other front end portion is regulated by being extended forward.
[0013]
Further, when two or more veneer single plates are conveyed in a stacked state, the front end portions of the stacked veneer single plates conveyed forward by the driving body are stopped by the stop body for an arbitrary time. A horizontal component force in the forward direction and a vertical component force in the up and down direction are applied to the veneer plates stacked for this arbitrary time.
[0014]
Therefore, when the vertical motion is applied to the veneer single plate by the driving body, a gap is formed between the veneer single plates stacked in the vertical direction. The lower veneer single plate is given a forward feeding force by the driving body, but the feeding is restricted by the stop body. On the other hand, the upper veneer veneer is once released from the sliding resistance with the lower veneer veneer and receives a forward feeding force, and then freely falls onto the lower veneer veneer by its own weight. Then, by continuing this state for an arbitrary time, the front edges in the feeding direction are aligned and aligned in the vertical direction.
[0015]
The amplitude applied to the driving body is preferably 5 to 50 mm, and more preferably 10 to 3 mm. And this stop body can also be able to undulate with respect to the conveyance surface of a veneer veneer. In this way, after the front end portion of the veneer veneer is regulated by the stopping body for an arbitrary time, the veneer veneer in which each front end portion is aligned by lying down below the conveying surface is, for example, as described above. Therefore, it is possible to smoothly carry out the subsequent bonding process smoothly.
[0016]
In order to solve the above-mentioned problems, the configuration of the end regulating device for the veneer veneer of the present invention is as follows:
A drive body that also gives up and down movement while feeding the veneer veneer forward;
A stop body that is located in the feeding direction of the veneer veneer and that is installed in a direction intersecting with the feeding direction of the veneer veneer and can be raised and lowered with respect to the conveying surface of the veneer veneer,
At least.
[0017]
Moreover, in order to solve the said subject, the structure of the edge part control apparatus of the veneer veneer of this invention is the following.
A driving body that applies a vertical movement to the stacked veneer single plates while feeding forward the veneer single plates in a state of being stacked on at least two sheets;
A stop body that is located in the feeding direction of the veneer veneer and that is installed in a direction intersecting with the feeding direction of the veneer veneer and can be raised and lowered with respect to the conveying surface of the veneer veneer,
At least.
[0018]
At least one pair of the driving bodies is installed in the feeding direction of the veneer single plate. Then, an operating body is connected to vibrate the drive body with a certain amplitude to give a motion in a direction in which the veneer single plate is combined forwardly and vertically. For example, this actuating body imparts forward feeding and vertical movement to the veneer single plate by the eccentric rotation of the coupling tool pivotally supported by the driving body and the eccentric ring.
[0019]
For example, a support spring is attached to the drive body on the gantry in a moving direction. The support spring is a torsion coil spring for compression, and is configured by attaching a high friction member to a pair of rails laid in parallel with the feeding direction in a state where free vibration is allowed by the support spring. Yes. The fixtures attached to the pair of rails are linked via a linkage to a rotating shaft that is pivotally supported by a bearing located at a substantially central portion of the gantry. Then, an eccentric wheel and a rotation transmission member are attached to the rotating shaft and rotated eccentrically, and the pair of rails are vibrated with a constant amplitude determined by the number of rotations and the amount of eccentricity of the eccentric wheel, and the laminated veneer single plate is moved in the forward direction. A horizontal component force and a vertical component force in the vertical direction are applied.
[0020]
In addition, instead of the method of vibrating the operating body with a constant amplitude determined by the rotational speed and the amount of eccentricity of the eccentric wheel, the veneer single plate is moved by the expansion and contraction by the fluid cylinder and the piston rod attached to the driving body. It is also possible to give a movement in a direction in which the forward feeding and the vertical direction are combined.
[0021]
Furthermore, the direction in which the forward extension and the vertical direction are synthesized with respect to the veneer single plate also by reciprocating movement accompanying the cam mechanism attached to the drive body or by ON / OFF control of the electromagnet attached to the drive body. It is also possible to give a movement to.
[0022]
The stopping body is located in front of the driving body and is provided separately from the driving body. Then, when the driving body vibrates with a certain amplitude toward the stop body and feeds the veneer single plate forward, the front end of the veneer single plate is stopped by the stop body. Further, the stop body can be installed integrally with the drive body. In this case, when the drive body vibrates at a certain amplitude and the veneer single plate is fed forward, the front end of the veneer single plate is stopped by the stop body that vibrates integrally with the drive body.
[0023]
In addition, within an interval in a direction crossing the feeding direction of each driving body, preferably, at least a pair of transport bodies for transporting the veneer veneer to the next process when the stop body falls down below the transport surface is provided. ing. That is, in order to convey the veneer veneer in which the vertical edges are aligned to the next stage process within the pair of rails, a pair of belts, chains, etc. from the upstream position to the downstream position of the stop body An endless conveyor is installed.
[0024]
And in the former drive body by a rail, even if the fiber direction of the veneer veneer is a direction intersecting with the feeding direction, the front end portion of the veneer veneer can be conveyed without buckling in the feeding direction.
[0025]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the accompanying drawings.
As shown in FIGS. 1 and 2, the driving body 1 imparts a vertical movement while feeding a single veneer single plate 2 or veneer single plates 2 and 3 stacked in the vertical direction forward. In addition, at least a pair of rails 4 and 5 are installed in the feeding direction of the veneer single plates 2 and 3. That is, the other end of the support 7 pivotally supported by the mount 6 is pivotally supported by the lower portions of the pair of rails 4 and 5, and the support spring 8 is supported by the support 7. Is attached.
[0026]
This support spring 8 is a torsion coil spring for compression, and holds the gantry 6, rails 4, 5, and support 7 in a parallelogram shape in a normal state. The pair of rails 4 and 5 laid in parallel with the feeding direction of the veneer single plates 2 and 3 are allowed to vibrate freely by the support spring 8. A high friction member 9 such as rubber or woven cloth is attached to the upper portions of the rails 4 and 5, and two veneer single plates 2 and 3 are placed on the upper surface of the high friction member 9.
[0027]
An actuator 10 is attached to the pair of rails 4 and 5 to impart movement in a direction in which the feeding direction and the vertical direction are combined. The operating body 10 is linked to a rotating shaft 12 supported by a bearing located at a substantially central portion of the gantry 6 via a linking tool 13 with a mounting tool 11 attached to a pair of rails 4 and 5. . Then, a rotation transmission member 14 such as a belt or a chain is wound around the rotary shaft 12 and rotated by a prime mover 15, and eccentric rings 16 attached to both ends of the rotary shaft 12 are rotated eccentrically. In this way, the pair of rails 4 and 5 are vibrated with a constant amplitude determined by the rotational speed and the amount of eccentricity of the eccentric ring 16, and moved forward to the single veneer single plate 2 or the stacked veneer single plates 2 and 3. A horizontal component force in the direction and a vertical component force in the vertical direction are applied.
[0028]
Further, a support shaft 17 is stretched downstream of the drive body 1 in a direction intersecting with the feeding direction of the veneer single plates 2 and 3, and a stop body 18 attached to the support shaft 17 at a predetermined interval. is set up. In this case, the stop body 18 is located in front of the drive body 1 and is installed separately from the drive body 1. Then, the driving body 1 vibrates with a certain amplitude toward the stop body 18 by the eccentric rotation of the operating body 10, that is, the eccentric wheel 16, and the single veneer single plate 2 or the stacked veneer single plates 2 and 3 are moved forward. When the sheet is fed out, the single veneer single plate 2 or the stacked veneer single plates 2 and 3 are once separated from the driving body 1 and moved in a direction in which the feeding direction and the vertical direction are combined. And when the front end part of the single veneer single plate 2 or the laminated veneer single plates 2 and 3 is stopped by the stop body 18, it freely falls onto the drive body 1 from the stop position with the stop body 18. By repeating this, the front end portion of the single veneer single plate 2 or the overlapped veneer single plates 2 and 3 is restricted to the stop body position.
[0029]
Further, the stop body 18 can be installed integrally with the drive body 1. That is, as shown in FIG. 3, a support shaft 17 is pivotally supported between the pair of rails 4 and 5 via a bracket 20, and a stop body 18 is attached to the support shaft 17 at a predetermined interval. The body 1 and the stop body 18 are integrally operated. Even in this case, when the eccentric veneer 16 is vibrated with a certain amplitude toward the stop body 18 due to the eccentric rotation, the single veneer single plate 2 or the stacked veneer single plates 2 and 3 are fed forward. One veneer single plate 2 or the overlapped veneer single plates 2 and 3 are once separated from the driving body 1 and moved in a direction in which the feeding direction and the vertical direction are combined. And, when the front end portion of the single veneer veneer 2 or the stacked veneer veneers 2 and 3 is stopped by the stop body 18, it freely falls from the stop position with the stop body 18 onto the drive body 1. However, the stop body 18 also moves together with the drive body 1 to the retreat limit of the amplitude. Accordingly, the single veneer veneer 2 or the overlapped veneer veneers 2 and 3 are free to fall while maintaining contact with the stop body 18.
[0030]
The stop body 18 may be installed on the entire front end portion of the veneer single plates 2 and 3, but preferably a plurality of the stop bodies 18 intersect the feeding direction of the veneer single plates 2 and 3, for example, cross the transport direction. A pair is installed at an arbitrary interval in the direction. And the front-end part of the veneer single board 2 and 3 conveyed ahead by the drive body 1 is stopped by the stop body 18 only for arbitrary time. During this arbitrary time, the veneer single plates 2 and 3 are given horizontal component force in the forward direction and vertical component force in the vertical direction. If a single veneer veneer 2 on the way of conveyance is biased to the left or right (see the veneer veneer indicated by the solid line in FIG. 4), the driver 1 is moved as described above. By oscillating for an arbitrary time, the front end portion that reaches first is stopped by the stop body 18 and the other front end portion is regulated forward by being forwarded (see the two-dot chain line in FIG. 4).
[0031]
In addition, when two or more veneer single plates 2 and 3 are conveyed in a stacked state, the front end portions of the stacked veneer single plates 2 and 3 conveyed forward by the driving body 1 are for an arbitrary time. Stopped by the stop body 18. A horizontal component force in the forward direction and a vertical component force in the vertical direction are applied to the veneer single plates 2 and 3 that are overlapped for this arbitrary time.
[0032]
The support shaft 17 can raise and lower the stop body 18 with respect to the conveying surface of the veneer single plates 2 and 3 by rotating the motor 19 or the like forward and backward by about 90 degrees, for example. At least a pair of transport bodies that transport the veneer single plates 2 and 3 to the next process when the stop body 18 falls below the transport surface within an interval in a direction intersecting with the feeding direction of each drive body 1. 21 is provided.
[0033]
That is, within the interval between the pair of rails 4 and 5, the veneer single plates 2 and 3 whose vertical edges are aligned are transferred to the next stage process, and therefore, from the upstream position to the downstream position of the stop body 18. A pair of belts or an endless conveyor such as a chain is installed.
[0034]
Therefore, when the rotating shaft 12 rotates to give a constant amplitude to the pair of rails 4 and 5 via the eccentric ring 16, the veneer single plates 2 and 3 stacked in the vertical direction are fed out (see FIG. 5). . Next, when the front end reaches the standing body 18 in the standing state, each front end portion is stopped by the stopping body 18 for an arbitrary time (see FIG. 6). A horizontal component force in the forward direction and a vertical component force in the vertical direction are applied to the veneer single plates 2 and 3 that are overlapped for this arbitrary time. When the vertical movement is applied to the veneer single plates 2 and 3 by the pair of rails 4 and 5, a gap is formed between the veneer single plates 2 and 3 stacked in the vertical direction (see FIG. 7). ). At this time, a forward feeding force by the driving body 1 is applied to the lower veneer single plate 3, but the feeding is restricted by the stop body 18. On the other hand, the upper veneer veneer 2 receives a forward feeding force once released from the sliding resistance with the lower veneer veneer 3, and then freely falls onto the lower veneer veneer 3 by its own weight. .
[0035]
By continuing this state for an arbitrary time, the front edge in the feeding direction is aligned and aligned in the vertical direction (see FIG. 8). Next, the veneer single plates 2 and 3 in which the front end portions are aligned are conveyed to the next stage process by causing the stop body 18 to fall below the conveyance surface.
[0036]
In particular, when the driving body 1 is constituted by a pair of rails 4 and 5, even if the fiber direction of the veneer single plates 2 and 3 intersects with the feeding direction, the front ends of the veneer single plates 2 and 3 The part can be conveyed without buckling in the feeding direction. Further, the drive body 1 having the latter rotating structure is an effective means when the fiber direction of the veneer single plates 2 and 3 is parallel to the feeding direction.
[0037]
Further, in place of the method of vibrating the operating body 10 with a constant amplitude determined by the rotational speed and the amount of eccentricity of the eccentric ring 16 as described above, a fluid cylinder 22 attached to the driving body 1 as shown in FIG. A piston rod 23 can also be used. That is, the piston rod 23 is expanded and contracted by supplying and discharging fluid to and from the front and rear cylinder chambers of the fluid cylinder 22, so that the single veneer single plate 2 and the veneer single plates 2 and 3 stacked in the vertical direction are Thus, it is also possible to give a movement in a direction in which the forward feeding and the vertical direction are combined.
[0038]
Furthermore, although not shown in any case, a single veneer veneer 2 can be obtained by reciprocating motion associated with a cam mechanism attached to the drive body 1 or by ON / OFF control of an electromagnet attached to the drive body 1. It is also possible to give a motion in a direction in which the forward feeding and the vertical direction are combined to the veneer single plates 2 and 3 stacked in the vertical direction.
[0039]
The present invention follows the fundamental technical idea, and can be implemented by changing a part of the above-described embodiments within a range that does not significantly impair the effects of the invention. Included in the range.
