- 前記型締シリンダにサブタンクを付設し、前記型開区間及び前記減速区間では、前記サブタンクと前記型締シリンダの後油室を接続して前記後油室内の作動油を前記サブタンクに流入させる制御を行うことを特徴とする請求項1記載の型締装置の制御方法。
- 前記減速区間では、この減速区間の所要時間を設定し、前記減速区間の減速開始位置から前記仮想停止位置に達する時間が前記所要時間となる制御を行うことを特徴とする請求項1記載の型締装置の制御方法。
- 前記停止制御処理では、停止位置で前記型締シリンダに対する作動油の全ての出入を遮断し、かつ油圧ポンプの作動を所定時間遅延させて停止させる制御を行うことを特徴とする請求項1記載の型締装置の制御方法。
- 前記停止制御処理では、前記型開速度よりも低速に設定した終期速度により型開きを行う終期型開区間と、前記終期型開区間の終了点から型開停止位置に向けて漸次減速させる終期減速区間と、前記型開停止位置における前記終期速度よりも低速となる所定の最終停止速度を設定した停止制御区間とを含む所定の終期速度制御パターンを設定し、停止制御処理時に、前記終期型開区間では、前記終期速度により型開制御を行い、かつ検出した現型開速度及び現型開位置に基づき前記型開停止位置で停止する前記終期減速区間の減速開始位置を所定時間間隔毎に演算により順次予測し、この減速開始位置に達したなら前記終期減速区間を開始するとともに、前記終期減速区間では、検出した現型開位置に基づき前記終期速度制御パターンに対応する速度指令値を順次演算により求め、この速度指令値により減速制御を行い、前記最終停止速度に達したなら所定の最終停止処理を行うことを特徴とする請求項1又は2記載の型締装置の制御方法。
- 前記終期減速区間では、この終期減速区間の終期所要時間を設定し、前記終期減速区間の減速開始位置から前記型開停止位置に達する時間が前記終期所要時間となる制御を行うことを特徴とする請求項6記載の型締装置の制御方法。
