上記検知においては、第1のローラ部材7の上記幅方向両端部領域の分力F1、F2、分力F1’、F2’を検知し、
上記調整においては、第1及び第2のローラ部材7、8の少なくとも1つ(ここでは第1のローラ部材7)の配置を調整することによって、上記幅方向両端部領域の分力F1、F2、分力F1’、F2’を上記所定のバランスになるように調整する。
上記検知では、互いに異なる3つの方向に沿う3つの力〔(Fa、Fb、Fc)、(Fa’、Fb’、Fc’)〕と、該各方向を軸としてそのまわりに回転する3つのモーメント〔(Ma、Mb、Mc)、(Ma’、Mb’、Mc’)〕との6つの力から選択される複数の力Fb、Fc、及び、複数の力Fb’、Fc’を、上記複数の分力F1、F2、及び、分力F1’、F2’として検知する。
従って、簡単、且つ、確実に、シート部材30の張力バラツキを十分に抑制できる。
なお、上記第1実施形態と共通する部分については、共通する符号を付して説明を繰り返さない。
また、圧接力Nの方が張力T1よりも大きく設定されており、これにより、第1のローラ部材7が第3のローラ部材9に圧接されるようになっている。
上記した第1のローラ部材7と第3のローラ部材9とでシート部材30を挟みつつ下流側に搬送する。
また、上記した検知部21、21’によって、張力T1、T2、及び圧接力Nによって各端部11a、11bにかかる合計の力を、上記b軸方向とc軸方向とに分けて、各方向の分力F1、F2を含む合力Ft1、Ft2、各方向の分力F1’、F2’を含む合力Ft1’、Ft2’を検知する。
そして、制御部25によって、合力Ft1、Ft2、合力Ft1’、Ft2’から、圧接力Nに起因する力を差し引いて、分力F1、F2、分力F1’、F2’を算出し、この分力F1、F2、分力F1’、F2’を所定のバランスになるように調整する。
かかる構成によれば、自由回転する従動ローラよりもシート部材30の傾きに影響を及ぼし易い駆動ローラにおいて、その傾きを抑制し得るため、より有用となる。
また、本実施形態のシート部材30の搬送方法においては、第1のローラ部材7が回転駆動力によって駆動される駆動ローラ23である。
かかる構成によれば、上記同様、自由回転する従動ローラよりもシート部材30の傾きに影響を及ぼし易い駆動ローラにおいて、その傾きを抑制し得るため、より有用となる。
例えば、シート部材30の幅方向両端部に、エアダンパーやエアノズルで空気を吹き付け、その風圧によって、シート部材30の幅方向両端部の分力F1、F2、分力F1’、F2’を所定のバランスに調整してもよい。
また、例えば、シート部材30の幅方向両端部を、加熱装置等で加熱することによって、シート部材30の幅方向両端部の分力F1、F2、分力F1’、F2’を所定のバランスに調整してもよい。
また、ローラ部材の配置を調整する態様として、ローラ部材の傾きを調整する態様を採用してもよい。
