【発明の属する技術分野】
本発明は板材への樹脂シート貼着方法及び貼着装置に関する技術分野に属し、詳細には、板材へビニールシート等の樹脂シートを貼着する方法及び装置に関する技術分野に属するものである。
【0002】
【従来の技術】
従来の板材への樹脂シート貼着技術としては、特公平1−51287号公報記載のビニールシート貼着技術がある。この公報記載の技術は、搬送する先行板材の後端部位置を検出した後、所定距離(L1)移動させて停止させ、次の搬送する後続板材の先端部位置を検出後に所定距離(L2)移動させて停止させ、先行板材の後端部と後続板材の先端部との間に所定間隔(L3=L1−L2)を形成させ、この後、先行板材と後続板材とを同時に同速度で所定距離(L4)移動させて該板材の表面にビニールシート貼着用ピンチロールによりビニールシートを貼着した後、先行板材と後続板材とを同時に停止させ、先行板材と後続板材との間のビニールシートをビニール切断装置により切断し、この後、前記先行板材を搬送することを特徴とする板材へのビニールシート貼着方法である。この公報記載の技術に用いられる装置の上面図及び側面図を図5及び図6に示す。
【0003】
上記板材へのビニールシート貼着方法において、先行板材の所定距離(L1)の移動については、搬送状態の先行板材の後端部位置を位置検出器39により検出した時に該位置検出器39から制御装置に信号を送り、その信号により制御装置からパルス発信器37,42にカウント開始の信号を送り、設定数をカウントした時に板材搬送用サーボモータ38,43を停止させて前記位置検出器39から距離L1の位置で先行板材を停止させる方法により、行われている。
【0004】
後続板材の所定距離(L2)の移動についても、基本的に上記と同様の方法により行われている。即ち、搬送状態の後続板材の先端部位置を前記位置検出器39により検出した時に該位置検出器39から制御装置に信号を送り、その信号により制御装置からパルス発信器37にカウント開始の信号を送り、設定数をカウントした時に板材搬送用サーボモータ38を停止させて前記位置検出器39から距離L2の位置で後続板材を停止させる方法により、行われている。この結果として、先行板材の後端部と後続板材の先端部との間に所定間隔(L3=L1−L2)が形成される。
【0005】
この後、ビニールシート貼着に際し、先行板材と後続板材とを同時に同速度で所定距離(L4)移動させる。この所定距離(L4)の移動については、この移動開始時からパルス発信器42が所定距離(L4)に相当するカウントを行った時に板材搬送用サーボモータ38,43を停止させて先行板材と後続板材とを同時に停止させる方法により、行われている。この結果として、先行板材の後端部と後続板材の先端部との間の所定間隔(L3)部がビニール切断装置上に位置するようにし、そして、この所定間隔(L3)部のビニールシートをビニール切断装置45により切断するようにしている。
【0006】
ビニールシート貼着用ピンチロールによる板材表面へのビニールシートの貼着については、詳細には、ビニールシート47を巻き付けたリール48を巻き戻してリール48からビニールシート47を繰り出し、エクスパンダロール49を介してビニールシート貼着用ピンチロール41により板材表面へビニールシートを貼着する方法により、行われている。
【0007】
このような板材表面へビニールシートを貼着する方法は、特公平1−51287号公報記載の技術において適用されるだけでなく、広く用いられている。この際、ビニールシート貼着用ピンチロールの硬度や形状により、ビニールシートの貼着を精度よく(未貼着部や気泡混入がないように)行う試みがなされてきた。
【0008】
なお、図5〜6において、31は板材、32は板材搬入テーブル、33は板揃え用傾斜ロール、35は板揃え堅ガイドロール、36は板送り用ピンチロール、40は板材受テーブル、44は押え具、46は板材搬出コンベア、51はチェーン、52はクラッチ、53はモータを示すものである。
【0009】
【発明が解決しようとする課題】
前記特公平1−51287号公報記載の板材へのビニールシート貼着方法においては、前記の如く、搬送状態の先行板材の後端部位置を位置検出器により検出した時からパルス発信器により設定数をカウントした時に先行板材の搬送を停止させることにより、先行板材を所定距離(L1)移動させようとし、これにより先行板材の停止時の位置決めをしようとしている。また、搬送状態の後続板材の先端部位置を前記位置検出器により検出した時からパルス発信器により設定数をカウントした時に後続板材の搬送を停止させることにより、後続板材を所定距離(L2)移動させようとし、これにより後続板材の停止時の位置決めをしようとしている。そして、先行板材の後端部と後続板材の先端部との間に所定間隔(L3)を形成させようとしている。
【0010】
従って、上記先行板材の移動距離も後続板材の移動距離もパルス発信器による設定数のカウントにより検出されることになるが、このような検出は直接的な検出でなく間接的な検出であり、搬送しようとする板材と板材搬送用ロールとの間での滑りや、板材の寸法(重量)の相違による慣性力の差により、検出誤差が生じるので、検出精度が悪く、このため、移動距離のL1もL2も誤差が大きいものとなる。また、上記移動距離の起点(基準点)は、位置検出器により板材の端部位置(後端部位置あるいは先端部位置)が検出されたとする時点での板材の位置であり、これは正確であるとは限らず、前記位置検出器の検出精度の相違によって異なる。この結果、先行板材の停止時の位置決めも後続板材の停止時の位置決めも正確でなく、誤差が大きくなる。即ち、先行板材の場合も後続板材の場合も停止位置精度が悪くなる。このため、先行板材の後端部と後続板材の先端部との間に形成される間隔のL3も誤差が大きいものとなる。
【0011】
また、前記特公平1−51287号公報記載の板材へのビニールシート貼着方法においては、前記の如く、先行板材及び後続板材の同時移動開始時からパルス発信器により所定距離(L4)に相当するカウントをした時に先行板材及び後続板材を同時に停止させることにより、先行板材及び後続板材を所定距離(L4)移動させようとし、これにより先行板材及び後続板材の停止時の位置決めをしようとしている。そして、これにより先行板材の後端部と後続板材の先端部との間の所定間隔(L3)部をビニール切断装置上に位置させ、この後、先行板材の後端部と後続板材の先端部との間のビニールシートを切断しようとしている。
【0012】
従って、上記先行板材及び後続板材の移動距離はパルス発信器による所定数のカウントにより検出されることになるが、かかる検出は間接的な検出であり、前記移動距離L1、L2の検出の場合と同様の理由により、検出精度が悪いため、移動距離のL4は誤差が大きいものとなる。このため、先行板材及び後続板材の停止時の位置決めが正確でなく、誤差が大きくなる。即ち、先行板材及び後続板材の停止位置精度が悪くなる。
【0013】
この結果、先行板材の後端部と後続板材の先端部との間のビニールシートを切断するに際し、寸法的な精度が悪く、安定した寸法精度でビニールシートを切断することができず、このため、ビニールシート切断後の板材に対するビニールのはみ出し量(残り代)も安定せず、人手等により再度残り代を切除する必要がある。更に、先行板材の後端部と後続板材の先端部との間に形成する間隔のL3を小さい(狭い)値に設定した場合にはビニールシートを切断することすらできないという問題点も生じることになる。
【0014】
そこで、実際には、先行板材の後端部と後続板材の先端部との間に形成する間隔のL3を大きい(広い)値(30mm以上)に設定する必要があるが、この場合には板材に対し長めにビニールシートを切断することになり、好ましくないことになる。また、依然として安定した寸法精度でビニールシートを切断することができないため、ビニールシート切断後の板材に対するビニールのはみ出し量も安定せず、人手等により再度残り代を切除する必要があるという問題点がある。
【0015】
一方、ビニールシート貼着用ピンチロールによる板材表面へのビニールシートの貼着に際し、前述の如く、ビニールシート貼着用ピンチロールの硬度や形状により、ビニールシートの貼着を精度よく(未貼着部や気泡混入がないように)行う試みがなされてきたが、かかる方法では鋼板やアルミ板等のような歪みのある板材の場合に板材の表面の端部において貼着不良が生じていた。例えば、ラジアルクラウンを付けること等によりビニールシート貼着用ピンチロール形状を変化させたり、ピンチロールの硬度を変化させても、板材の表面の端部において貼着不良が生じていた。これは、歪みの大きい板材の場合、ピンチロール表面の変形が板材の歪み形状に追従できないためである。
【0016】
本発明は、このような事情に着目してなされたものであって、その目的は、搬送する先行板材を停止させ、次の搬送する後続板材を停止させると共に前記先行板材の後端部と後続板材の先端部との間に一定の間隔を形成させ、この両板材を搬送しながら板材表面にビニールシート等の樹脂シートを貼着し、停止させた後、先行板材の後端部と後続板材の先端部との間の樹脂シートを切断するに際し、前記従来の板材への樹脂シート(ビニールシート)貼着方法による場合に比較して、寸法的な精度に優れ、安定した寸法精度で樹脂シートを切断することができる板材への樹脂シート貼着方法及び貼着装置、更には、板材表面の端部でも樹脂シートを良好に貼着することができ、樹脂シートの貼着を精度よく行うことができる板材への樹脂シート貼着装置を提供しようとするものである。
【0017】

【0021】
請求項4記載の板材への樹脂シート貼着装置は、搬送する先行板材を停止させ、次の搬送する後続板材を停止させると共に前記先行板材の後端部と後続板材の先端部との間に一定の間隔を形成させた後、この先行板材と後続板材とを同時に同速度で搬送しながら板材表面に樹脂シートを貼着する手段と、この手段により樹脂シートを貼着した後に先行板材と後続板材との間の樹脂シートを切断する樹脂シート切断装置とを有する板材への樹脂シート貼着装置であって、前記先行板材の後端部と後続板材の先端部との間の間隔を一定値に調整するスペーサを設けたことを特徴とする板材への樹脂シート貼着装置である(第4発明)。
【0022】
請求項5記載の板材への樹脂シート貼着装置は、前記スペーサが、先行板材の停止後搬送前に先行板材の後端部と後続板材の先端部とに挟まれた後に通板路から退避する可動式のスペーサであることを特徴とする請求項4記載の板材への樹脂シート貼着装置である(第5発明)。請求項6記載の板材への樹脂シート貼着装置は、前記スペーサが、通板路から退避可能であると共に板材搬送方向およびその逆方向に移動可能であることを特徴とする請求項4又は5記載の板材への樹脂シート貼着装置である(第6発明)。
【0023】
請求項7記載の板材への樹脂シート貼着装置は、前記搬送する先行板材の後端部位置を検出する位置検出センサーと後続板材の先端部位置を検出する位置検出センサーとを設けたことを特徴とする請求項4、5又は6記載の板材への樹脂シート貼着装置である(第7発明)。
【0024】

【0025】
また、請求項9記載の板材への樹脂シート貼着装置は、前記樹脂シートを貼着する手段として、樹脂シート貼着用ピンチロールを設けると共に、このピンチロールによる樹脂シート貼着後の板材の表面の端部を押しながら回転する端部貼着補助ロールを設けたことを特徴とする請求項4、5、6、7又は8記載の板材への樹脂シート貼着装置である(第9発明)。
【0026】
【発明の実施の形態】
本発明は、例えば次のような形態で実施する。
搬送する先行板材を停止させ、次の搬送する後続板材を停止させると共に前記先行板材の後端部と後続板材の先端部との間に一定の間隔を形成させた後、この先行板材と後続板材とを同時に同速度で搬送しながら板材表面に樹脂シートを貼着する手段(以下、樹脂シート貼着手段ともいう)と、この手段により樹脂シートを貼着した後に先行板材と後続板材との間の樹脂シートを切断する樹脂シート切断装置とを設け、更に、前記先行板材の後端部と後続板材の先端部との間の間隔を一定値に調整するスペーサを設ける。ここで、樹脂シート貼着手段については、より具体的には、例えば、板材を水平に左から右へ搬送する板材の搬送手段と、この搬送手段により搬送される板材の表面に樹脂シートを貼着する樹脂シート貼着用ピンチロールと、樹脂シートが巻き付けられ、この樹脂シートを繰り出し、エクスパンダロールを介して前記樹脂シート貼着用ピンチロールに樹脂シートを供給するリールとを設けることにより、構成する。このようにして、本発明に係る板材への樹脂シート貼着装置をつくることができる。
【0027】
上記板材への樹脂シート貼着装置は、次のようにして用いることができ、それにより本発明に係る板材への樹脂シート貼着方法を行うことができる。樹脂シート貼着手段により、搬送する先行板材の後端部位置を検出して該先行板材を停止させた後、次の搬送する後続板材の先端部位置を検出して該後続板材を停止させると共に前記先行板材の後端部と後続板材の先端部との間に一定の間隔を形成させ、次に、前記先行板材と後続板材とを同時に同速度で搬送しながら板材表面にビニールシート等の樹脂シートを貼着し、前記先行板材と後続板材とを同時に停止させる。そして、前記先行板材と後続板材との間の樹脂シートを樹脂シート切断装置により切断し、この後、前記先行板材を搬送する。このとき、前記先行板材の後端部と後続板材の先端部との間の間隔をスペーサを用いて一定値に調整する。このようにして、本発明に係る板材への樹脂シート貼着方法が行われる。
【0028】
このような板材への樹脂シート貼着方法によれば、先行板材の後端部位置及び後続板材の先端部位置の検出により先行板材及び後続板材の停止位置精度に優れていると共に、先行板材の後端部と後続板材の先端部との間に形成される間隔はスペーサの寸法(厚み)により定まり、これは誤差がなく、精度よく正確に所定の一定間隔L(=スペーサの厚み)に調整することができる。この調整に際し、板材と板材搬送用ロールとの間での滑りや板材の寸法(重量)の相違による慣性力の差が影響しないので、この調整の精度は極めて高く、常に安定して所定一定間隔Lに調整することができる。
【0029】
上記所定一定間隔Lの形成の後、前記先行板材と後続板材とを同時に同速度で搬送しながら樹脂シートを貼着した後、前記先行板材と後続板材とを同時に停止させるので、所定一定間隔Lをそのまま維持した状態で停止させることができ、この状態で前記先行板材と後続板材との間の樹脂シートを樹脂シート切断装置により切断することができる。
【0030】
従って、本発明に係る板材への樹脂シート貼着方法によれば、先行板材の後端部と後続板材の先端部との間の樹脂シートを切断するに際し、寸法的な精度に優れ、安定した寸法精度で樹脂シートを切断することができるようになる。このため、この樹脂シート切断後の板材に対する樹脂シートのはみ出し量(残り代)が安定し、人手等により再度残り代を切除する必要がなくなる。更に、先行板材の後端部と後続板材の先端部との間に形成する間隔(所定一定間隔L)を小さい値に設定した場合でも樹脂シートを切断することが可能となり、このため、樹脂シート切断後の板材に対する樹脂シートのはみ出し量を安定させて極めて少なくすることができ、再度残り代を切除する必要がなくなる。
【0031】
前記スペーサによる先行板材の後端部と後続板材の先端部との間の間隔の調整は、より具体的には、例えば、次のようにして行う。前記先行板材を停止させた後、後続板材の先端部をスペーサに当接させた状態で前記先行板材の後端部と接触する位置まで搬送して停止させた後、前記スペーサを退避させることにより、前記先行板材の後端部と後続板材の先端部との間の間隔を一定値に調整する(第2発明)。そうすると、間隔調整の操作性がよく、操業性の低下を招かずに正確に所定一定間隔L(=スペーサの厚み)に調整することができる。
【0032】
前記樹脂シートを切断する位置で先行板材の後端部と後続板材の先端部との間の間隔部をセンサーにより検出して、前記先行板材と後続板材とを同時に停止させるようにすると、この停止の際の先行板材及び後続板材の停止位置精度に優れている(第3発明)。従って、先行板材と後続板材との間(所定一定間隔L部)の樹脂シートの中央部を容易に樹脂シート切断装置の切断部位置に位置させることができ、寸法的な精度に一層優れ、より安定した寸法精度で樹脂シートを切断することができるようになる。
【0033】
本発明に係る板材への樹脂シート貼着装置によれば、前記した本発明に係る樹脂シート貼着方法と同様の樹脂シート貼着方法を行うことができる。このため、先行板材の後端部と後続板材の先端部との間の樹脂シートを切断するに際し、寸法的な精度に優れ、安定した寸法精度で樹脂シートを切断することができるようになる。
【0034】
上記板材への樹脂シート貼着装置において、スペーサとしては、より具体的には例えば、先行板材の停止後搬送前に先行板材の後端部と後続板材の先端部とに挟まれた後に通板路から退避する可動式のスペーサを用いる(第5発明)。この可動式のスペーサを用いた場合、操作性がよく、操業性の低下を招くことなく、先行板材の後端部と後続板材の先端部との間の間隔を容易に且つ確実に所定一定間隔L(=スペーサの厚み)に調整することができる。このような可動式のスペーサとしては、例えば、通板路から退避可能であると共に板材搬送方向およびその逆方向に移動可能であるものを挙げることができる(第6発明)。
【0035】
搬送する先行板材の後端部位置を検出する位置検出センサーと後続板材の先端部位置を検出する位置検出センサーとを設けるようにすると、先行板材及び後続板材の停止位置精度が向上し、ひいては先行板材の後端部と後続板材の先端部との間の間隔の調整が容易になる(第7発明)。
【0036】
樹脂シートを切断する位置で先行板材の後端部と後続板材の先端部との間の間隔部を検出するセンサーを設けるようにすると、先行板材と後続板材とを同時に停止する際の停止位置精度が向上し、ひいては上記間隔部の樹脂シートの中央部を容易に樹脂シート切断装置の切断部位置に位置させることができ、寸法的な精度により優れ一層安定した寸法精度で樹脂シートを切断することができるようになる(第8発明)。ここで、上記センサーを樹脂シート切断装置と同一可動架台に設置し、先行板材及び後続板材の同時停止の後に、上記センサーにより先行板材の後端部と後続板材の先端部との間の検出を行うようにすると、先行板材の後端部と後続板材の先端部との間の樹脂シートの切断の際の寸法精度を更に向上させることができる。
【0037】
樹脂シートを貼着する手段として、樹脂シート貼着用ピンチロールを設けると共に、このピンチロールによる樹脂シート貼着後の板材の表面の端部を押しながら回転する端部貼着補助ロールを設けるようにすると、前記樹脂シート貼着用ピンチロールによる樹脂シート貼着後の板材の表面の端部を前記端部貼着補助ロールにより押して板材表面の端部での樹脂シートの貼着性を補強することができ、このため板材表面の端部でも樹脂シートを良好に貼着し得、樹脂シートの貼着を精度よく行うことができるようになる(第9発明)。即ち、樹脂シート貼着用ピンチロールによる樹脂シート貼着だけでは板材の表面の端部において貼着不良が生じるような歪みのある板材の場合でも、その貼着不良を前記端部貼着補助ロールにより補強することができ、結果として板材の表面の全面にわたって樹脂シートを良好に貼着することができるようになる。これは、前記端部貼着補助ロールにより、板材の歪み形状への追従が可能となるためである。
【0038】
ここで、前記端部貼着補助ロールにバネ力等による加圧装置を設けたり、前記端部貼着補助ロールを板材の進行方向(搬送方向)に対し板材の外縁部に気泡を押し出すように流れ方向に角度を設けて配置すると、さらに樹脂シートを良好に貼着することができ、樹脂シートの貼着精度を一層向上させることができる。また、樹脂シート貼着用ピンチロールを複数ならべて配置し、その間に前記端部貼着補助ロールを配置することにより、さらに樹脂シートの貼着精度が向上する。
【0039】
なお、本発明において、板材の表面への樹脂シートの貼着は板材の片面のみに行ってもよいし、板材の両面に行ってもよい。樹脂シートとは、樹脂よりなるシートのことである。樹脂シートとしては、種々のものがあり、その一つに例えばビニールシートがある。
【0040】
【実施例】
本発明の実施例を以下説明する。尚、本発明はこの実施例に限定されるものではない。
【0041】
(実施例1)
本発明の実施例1に係る板材への樹脂シート貼着装置の側面図及び上面図を示す図1及び図2に基づいて説明する。図において、符号6で示す板材搬入テーブルおよび符号7で示す板材搬出テーブルは、モータ9,10にてそれぞれ駆動される駆動ロール61,71と、該駆動ロール61,71に対してチェーンを介して従動される従動ロール62,721、722とから構成されている。符号4,4' , 5,5' は樹脂シート貼着用ピンチロールであり、上流側ピンチロール4,4' は上記駆動ロール61と同期回転するよう従動ロール62にクラッチ11を介して接続されている。下流側ピンチロール5,5' も同様に駆動ロール71と同期回転するよう従動ロール722にクラッチ12を介して接続されている。
【0042】
樹脂シート貼着部は、上記ピンチロール4,4' , 5,5' と、樹脂シートを巻回したシートリール1,1' と、該シートリールからピンチロールまで樹脂シートを送給するガイドロール2,2' およびテンションロール3,3' とから構成されている。そして、始動時には予め樹脂シートがピンチロールまで繰り出されている。従って、始動時には初回のみ先行板材の先端側に不要な樹脂シートが発生するが、その部分は適宜切断除去される。
【0043】
符号15は搬送される先行板材の後端部位置を検出する第1検出センサで、14は搬送される後続板材の先端部位置を検出する第2検出センサで、これらのセンサは光電式のセンサを用いたが他の方式によるセンサでも良い。17は、樹脂シートを切断する位置で先行板材の後端と後続板材の先端との間の間隔部を検出する第3検出センサで、帯状レーザにて間隔部を検出するレーザセンサを用いる方が精度が良くより好ましい。
【0044】
符号16はスペーサで、先行板材の後端と後続板材の先端との間の間隔を一定値に調整するものであり、通板路に対して退避可能で且つ前後方向にも移動可能に構成されている。
【0045】
符号18は先行板材の後端と後続板材の先端との間の間隔部に存在する不要な樹脂シートを切断する切断装置である。
【0046】
上記実施例1に係る樹脂シート貼着装置を用い、本発明に係る樹脂シート貼着方法により、板材への樹脂シート貼着を行った。この詳細を以下説明する。尚、樹脂シートとしてはビニールシートを用いた。
【0047】
板材搬入テーブル6により先行板材を搬入して樹脂シート貼着部に送り込み、この先行板材の後端部位置を第1検出センサ15で検出するとクラッチ11,12が同時に切り離され、先行板材が樹脂シート貼着部ゾーンに停止する。次いでスペーサ16が通板路に上昇して待機した状態となる。そこへ未だ駆動され続けている搬入テーブル6に後続板材が搬入され、その後続板材の先端部を第2検出センサ14が検知すると駆動モータ9,10のタイマが作動し、タイマオフで該駆動モータは停止する。
【0048】
従って、タイマ作動中に後続板材が上記スペーサ16に当接し、その状態で他端に先行板材の後端が当接するまで送り込まれる。即ち、上記スペーサ16の両面に両板材が当接するに必要な時間がタイマに予めセットされている。
【0049】
次に、前記スペーサ16を通板路から下降退避させ、この退避完了信号を受けてクラッチ11、12が接続され、駆動モータ9,10がオンされる。これらの作動は図示略した電気シーケンスによる制御盤にて制御するよう構成している。

駆動モータ9,10がオンされると、板材搬送テーブル6と板材搬出テーブル7との各ロールが作動し、クラッチ11、12を介して接続されたピンチロール4,5も同期して同速度で作動する。従って、前記先行板材と後続板材とは前記スペーサ16によりセッティングされた間隔を維持したまま搬送されながら、樹脂シート貼着部にて板材に樹脂シートが貼着される。
【0051】
このとき、リール1に巻き付けられた樹脂シート20は、ガイドロール2およびテンションロール3を介して樹脂シート貼着用ピンチロール4,5に送り込まれ、板材に貼着される。尚、板材の両面に樹脂シート貼着を行う場合には、リール1' 、ガイドロール2' 、テンションロール3' 、樹脂シート貼着用ピンチロール4' , 5' も用いることになる。

【0056】
また、上記実施例においては、第3検出センサ17により先行板材の後端部と後続板材の先端部との間の間隔部を検出して先行板材と後続板材とを同時に停止させ、先行板材と後続板材との間の樹脂シートを切断したが、第3検出センサ17を設けず、先行板材の後端部と後続板材の先端部との間に所定一定間隔Lを形成させた後、先行板材と後続板材とを同時に同速度で従来技術と同様な方法等により一定距離搬送して樹脂シートを貼着し、同時に停止させた場合においても、従来の方法による場合に比べて樹脂シート切断の際の寸法的精度に優れていた。但し、上記実施例の場合に比較すると、樹脂シート切断の際の寸法的精度が少し低下した。

BACKGROUND OF THE INVENTION
The present invention belongs to a technical field related to a resin sheet sticking method and a sticking apparatus to a plate material, and particularly to a technical field related to a method and a device for sticking a resin sheet such as a vinyl sheet to a plate material.
[0002]
[Prior art]
As a conventional resin sheet sticking technique to a plate material, there is a vinyl sheet sticking technique described in Japanese Patent Publication No. 1-51287. In the technique described in this publication, after detecting the rear end position of the preceding plate material to be conveyed, a predetermined distance (L 1 ) Move it to stop, detect the position of the tip of the next plate to be transported next, and then detect the distance (L 2 ) Move to stop, and a predetermined distance (L between the trailing edge of the preceding plate and the leading edge of the trailing plate Three = L 1 −L 2 ), And then, the preceding plate and the subsequent plate are simultaneously moved at a predetermined distance (L Four ) After moving and pasting the vinyl sheet on the surface of the plate material with a pinch roll for attaching the vinyl sheet, the preceding plate material and the subsequent plate material are stopped simultaneously, and the vinyl sheet between the preceding plate material and the subsequent plate material is vinyl cutting device This is a method of sticking a vinyl sheet to a plate material, characterized in that the preceding plate material is conveyed after cutting. A top view and a side view of an apparatus used in the technique described in this publication are shown in FIGS.
[0003]
In the method of attaching a vinyl sheet to the above plate material, a predetermined distance (L 1 )), The position detector 39 sends a signal to the control device when the rear end position of the preceding plate in the transport state is detected by the position detector 39, and the signal is sent from the control device to the pulse transmitters 37 and 42. When the set number is counted, the plate material transfer servo motors 38 and 43 are stopped and the distance L from the position detector 39 is sent. 1 This is done by a method of stopping the preceding plate material at the position.
[0004]
Predetermined distance (L 2 ) Is basically performed in the same manner as described above. That is, when the position detector 39 detects the position of the leading edge of the subsequent plate in the transported state, a signal is sent from the position detector 39 to the control device, and a signal to start counting is sent from the control device to the pulse transmitter 37 based on the signal. When the feed and set number are counted, the plate material transfer servo motor 38 is stopped and the distance L from the position detector 39 is 2 This is done by a method of stopping the subsequent plate material at the position. As a result, a predetermined distance (L between the rear end of the preceding plate and the front end of the subsequent plate is obtained. Three = L 1 −L 2 ) Is formed.
[0005]
After this, when attaching the vinyl sheet, the preceding plate material and the subsequent plate material are simultaneously moved at the same speed at a predetermined distance (L Four ) Move it. This predetermined distance (L Four ) For the movement of the pulse transmitter 42 from the start of the movement at a predetermined distance (L Four ) Is performed by stopping the plate material conveying servomotors 38 and 43 and simultaneously stopping the preceding plate material and the subsequent plate material. As a result of this, a predetermined distance between the rear end of the preceding plate and the front end of the subsequent plate (L Three ) Part is located on the vinyl cutting device, and this predetermined interval (L Three ) Portion of the vinyl sheet is cut by a vinyl cutting device 45.
[0006]
For details on sticking a vinyl sheet to the surface of a plate using a pinch roll for attaching a vinyl sheet, in detail, the reel 48 around which the vinyl sheet 47 is wound is rewound, the vinyl sheet 47 is fed out from the reel 48, and the expander roll 49 is used. This is performed by a method of sticking a vinyl sheet to the surface of the plate material with a pinch roll 41 for sticking the vinyl sheet.
[0007]
Such a method of sticking a vinyl sheet to the surface of a plate material is not only applied in the technique described in Japanese Patent Publication No. 1-51287 but also widely used. At this time, attempts have been made to attach the vinyl sheet accurately (so that there is no unattached part or air bubbles) depending on the hardness and shape of the pinch roll attached to the vinyl sheet.

[0009]
[Problems to be solved by the invention]
In the method of sticking a vinyl sheet to a plate described in Japanese Patent Publication No. 1-51287, as described above, the number of pulses set by a pulse transmitter from the time when the position of the rear end of the preceding plate in the transported state is detected by a position detector. By stopping the conveyance of the preceding plate material when counting the 1 ) Trying to move it, and trying to position the leading plate when it stops. Further, when the set number is counted by the pulse transmitter from the time when the position of the leading end of the subsequent plate in the transport state is detected by the position detector, the subsequent plate is stopped by a predetermined distance (L 2 ) Trying to move, so that the subsequent plate is positioned when stopped. A predetermined distance (L) is provided between the rear end of the preceding plate and the front end of the subsequent plate. Three ).
[0010]
Therefore, the moving distance of the preceding plate material and the moving distance of the subsequent plate material will be detected by counting the set number by the pulse transmitter, but such detection is not direct detection but indirect detection, Detection error occurs due to slippage between the plate material to be conveyed and the plate material conveyance roll, and the difference in inertia force due to the difference in the size (weight) of the plate material, so the detection accuracy is poor. L 1 Also L 2 However, the error is large. Further, the starting point (reference point) of the moving distance is the position of the plate material when the end position (rear end position or front end position) of the plate material is detected by the position detector, which is accurate. Not necessarily, but it depends on the difference in detection accuracy of the position detector. As a result, the positioning at the time of stopping the preceding plate material and the positioning at the time of stopping the subsequent plate material are not accurate, and the error increases. That is, the stop position accuracy deteriorates in both the case of the preceding plate material and the case of the subsequent plate material. For this reason, the distance L formed between the rear end of the preceding plate and the front end of the subsequent plate Three However, the error is large.
[0011]
Further, in the method of sticking a vinyl sheet to a plate material described in Japanese Patent Publication No. 1-51287, as described above, a predetermined distance (L Four ) By stopping the preceding plate and the subsequent plate simultaneously at the same time, the preceding plate and the subsequent plate are separated by a predetermined distance (L Four ) Attempt to move, thereby trying to position the preceding and subsequent plates when stopped. Thus, a predetermined distance between the rear end of the preceding plate and the front end of the subsequent plate (L Three ) Portion is positioned on the vinyl cutting device, and then the vinyl sheet between the rear end portion of the preceding plate material and the front end portion of the subsequent plate material is to be cut.
[0012]
Therefore, the movement distance of the preceding plate material and the subsequent plate material is detected by a predetermined number of counts by the pulse transmitter, but such detection is indirect detection, and the movement distance L 1 , L 2 For the same reason as the detection of Four Has a large error. For this reason, positioning at the time of a stop of a preceding board material and a succeeding board material is not exact, and an error becomes large. That is, the stop position accuracy of the preceding plate material and the subsequent plate material is deteriorated.
[0013]
As a result, when cutting the vinyl sheet between the rear end of the preceding plate and the leading end of the subsequent plate, the dimensional accuracy is poor, and the vinyl sheet cannot be cut with stable dimensional accuracy. In addition, the amount of vinyl protruding from the plate material after cutting the vinyl sheet (remaining allowance) is not stable, and it is necessary to resect the remaining allowance again manually. Furthermore, the distance L formed between the rear end of the preceding plate and the front end of the subsequent plate Three When is set to a small (narrow) value, there is a problem that even the vinyl sheet cannot be cut.
[0014]
Therefore, in practice, the distance L formed between the rear end of the preceding plate and the front end of the subsequent plate Three Needs to be set to a large (wide) value (30 mm or more), but in this case, the vinyl sheet is cut longer than the plate material, which is not preferable. In addition, since the vinyl sheet cannot be cut with stable dimensional accuracy, the amount of the vinyl protruding from the plate after the vinyl sheet is cut is not stable, and it is necessary to manually remove the remaining margin again. is there.
[0015]
On the other hand, when the vinyl sheet is adhered to the surface of the plate material by the pinch roll to which the vinyl sheet is adhered, as described above, the vinyl sheet can be adhered with high accuracy (the unadhered portion or Attempts have been made to ensure that no air bubbles are mixed in. However, in such a method, in the case of a distorted plate material such as a steel plate or an aluminum plate, poor adhesion has occurred at the edge of the surface of the plate material. For example, even when the pinch roll shape to which the vinyl sheet is stuck is changed by attaching a radial crown or the hardness of the pinch roll is changed, poor sticking occurs at the end of the surface of the plate. This is because in the case of a plate material having a large strain, the deformation of the pinch roll surface cannot follow the strain shape of the plate material.
[0016]
The present invention has been made paying attention to such a situation, and its purpose is to stop the preceding plate material to be transported, stop the subsequent plate material to be transported next, and the rear end portion of the preceding plate material and the succeeding plate material. A fixed interval is formed between the front end of the plate material, a resin sheet such as a vinyl sheet is attached to the surface of the plate material while transporting both plate materials, and then stopped, then the rear end portion of the preceding plate material and the subsequent plate material When cutting the resin sheet between the tip of the resin sheet, the resin sheet has superior dimensional accuracy and stable dimensional accuracy compared to the conventional method of attaching a resin sheet (vinyl sheet) to the plate material. The resin sheet sticking method and the sticking device to the plate material that can cut the resin sheet, and the resin sheet can be satisfactorily stuck even at the end of the plate material surface, and the resin sheet is accurately stuck. Resin sheet to plate material It is intended to provide a sticking device.

DETAILED DESCRIPTION OF THE INVENTION
The present invention is implemented, for example, in the following form.
Stop the preceding plate material to be conveyed, stop the next plate material to be conveyed next, and form a certain interval between the rear end portion of the preceding plate material and the front end portion of the subsequent plate material, and then the preceding plate material and the subsequent plate material Means for adhering the resin sheet to the surface of the plate material while conveying the same at the same speed (hereinafter also referred to as resin sheet adhering means), and between the preceding plate material and the subsequent plate material after the resin sheet is adhered by this means And a spacer for adjusting the distance between the rear end portion of the preceding plate member and the front end portion of the subsequent plate member to a constant value. Here, more specifically, for example, the resin sheet adhering means is a means of adhering a resin sheet to the surface of the plate material conveyed by the conveying means for conveying the plate material horizontally from the left to the right. A resin sheet sticking pinch roll to be worn, and a resin sheet is wound around, and the resin sheet is fed out and provided with a reel that supplies the resin sheet to the resin sheet sticking pinch roll via an expander roll. . Thus, the resin sheet sticking apparatus to the board | plate material which concerns on this invention can be made.
[0027]
The resin sheet sticking apparatus to the said board | plate material can be used as follows, and can perform the resin sheet sticking method to the board | plate material which concerns on this invention by it. After detecting the rear end position of the preceding plate material to be conveyed by the resin sheet sticking means and stopping the preceding plate material, the leading edge position of the subsequent plate material to be conveyed next is detected and the subsequent plate material is stopped. A predetermined interval is formed between the rear end portion of the preceding plate material and the front end portion of the subsequent plate material, and then a resin such as a vinyl sheet on the surface of the plate material while simultaneously conveying the preceding plate material and the subsequent plate material at the same speed. A sheet is stuck and the preceding plate material and the subsequent plate material are stopped simultaneously. Then, the resin sheet between the preceding plate material and the subsequent plate material is cut by a resin sheet cutting device, and thereafter, the preceding plate material is conveyed. At this time, the interval between the rear end portion of the preceding plate material and the front end portion of the subsequent plate material is adjusted to a constant value using a spacer. Thus, the resin sheet sticking method to the board | plate material which concerns on this invention is performed.
[0028]
According to such a method of sticking a resin sheet to a plate material, the detection of the rear end position of the preceding plate material and the front end position of the subsequent plate material is excellent in the stop position accuracy of the preceding plate material and the subsequent plate material, The distance formed between the trailing edge and the leading edge of the subsequent plate is determined by the dimension (thickness) of the spacer, which is error-free and accurately adjusted to a predetermined constant distance L (= spacer thickness). can do. In this adjustment, there is no effect of slippage between the plate material and the plate material transport roll or the difference in inertia force due to the difference in the size (weight) of the plate material. L can be adjusted.
[0029]
After the formation of the predetermined constant interval L, the preceding plate member and the subsequent plate member are simultaneously stopped at the same speed, and after the resin sheet is adhered, the preceding plate member and the subsequent plate member are simultaneously stopped. In this state, the resin sheet between the preceding plate material and the subsequent plate material can be cut by the resin sheet cutting device.
[0030]
Therefore, according to the resin sheet sticking method to the plate material according to the present invention, when cutting the resin sheet between the rear end portion of the preceding plate material and the tip portion of the subsequent plate material, the dimensional accuracy is excellent and stable. The resin sheet can be cut with dimensional accuracy. For this reason, the protrusion amount (remaining allowance) of the resin sheet with respect to the plate material after cutting the resin sheet is stabilized, and it is not necessary to excise the remaining allowance again manually. Furthermore, the resin sheet can be cut even when the interval (predetermined constant interval L) formed between the rear end of the preceding plate and the leading end of the subsequent plate is set to a small value. The amount of protrusion of the resin sheet with respect to the cut plate material can be stabilized and extremely reduced, and there is no need to cut the remaining margin again.
[0031]
More specifically, for example, the adjustment of the distance between the rear end portion of the preceding plate material and the front end portion of the subsequent plate material by the spacer is performed as follows. After stopping the preceding plate material, transporting it to a position where it contacts the rear end portion of the preceding plate material in a state where the leading end portion of the subsequent plate material is in contact with the spacer, and then retracting the spacer The interval between the rear end of the preceding plate and the front end of the subsequent plate is adjusted to a constant value (second invention). If it does so, the operativity of space | interval adjustment is good and it can adjust to the predetermined fixed space | interval L (= spacer thickness) correctly, without causing the fall of operativity.
[0032]
When the gap between the rear end of the preceding plate and the leading end of the subsequent plate is detected by a sensor at the position where the resin sheet is cut, the preceding plate and the subsequent plate are stopped simultaneously. In this case, the leading plate material and the trailing plate material are excellent in stop position accuracy (third invention). Accordingly, the central portion of the resin sheet between the preceding plate material and the subsequent plate material (predetermined constant interval L portion) can be easily positioned at the cutting portion position of the resin sheet cutting device, and the dimensional accuracy is further improved. The resin sheet can be cut with stable dimensional accuracy.
[0033]
According to the resin sheet sticking apparatus to the board | plate material which concerns on this invention, the resin sheet sticking method similar to the above-mentioned resin sheet sticking method concerning this invention can be performed. For this reason, when cutting the resin sheet between the rear end portion of the preceding plate member and the leading end portion of the subsequent plate member, the resin sheet can be cut with excellent dimensional accuracy and with stable dimensional accuracy.
[0034]
In the resin sheet sticking device to the above plate material, as the spacer, more specifically, for example, a through plate after being sandwiched between the rear end portion of the preceding plate material and the front end portion of the subsequent plate material before conveyance after stopping the preceding plate material A movable spacer that retreats from the road is used (fifth invention). When this movable spacer is used, the operability is good, and the interval between the rear end of the preceding plate and the front end of the subsequent plate is easily and surely set at a predetermined constant interval without causing deterioration in operability. L (= spacer thickness) can be adjusted. An example of such a movable spacer is one that can be retracted from the plate passage and can be moved in the direction of conveying the plate material and in the opposite direction (sixth invention).
[0035]
