- 型開閉用サーボモータの駆動力をボールネジを介して伝達し可動盤を固定盤に対して移動させた後に型締機構により型締を行う射出成形機の制御方法において、
連続成形時に前記型開閉用サーボモータに付設されるロータリエンコーダにより検出される可動盤の位置から他のアクチュエータの作動開始確認位置を確認するとともに、前記作動開始確認位置の補正を行うことを特徴とする射出成形機の制御方法。 - 前記他のアクチュエータは型締シリンダであり、
可動盤が前記型締シリンダの作動開始確認位置に到達したことが確認されたら前記型締シリンダの作動を可能とするとともに、
連続成形時の成形サイクルのいずれかの間に前記型締シリンダの作動開始確認位置の補正を行うことを特徴とする請求項1に記載の射出成形機の制御方法。 - 型開閉用サーボモータの駆動力をボールネジを介して伝達し可動盤を固定盤に対して移動させた後に型締機構により型締を行う射出成形機において、
前記型開閉用サーボモータに付設され可動盤の位置を検出可能なロータリエンコーダと、
前記型開閉用サーボモータ以外の射出成形機の作動を行う他のアクチュエータと、
可動盤が他のアクチュエータの作動開始確認位置に到達したことが確認されたら前記他のアクチュエータの作動を可能とするとともに連続成形時に可動盤の位置を検出して前記作動開始確認位置の補正を行う制御装置とが備えられたことを特徴とする射出成形機。 - 前記型開閉用サーボモータとボールネジが挿通されるボールネジナットは、
いずれか一方がベッドまたは固定盤に配設され、いずれか他方が可動盤に配設されていることを特徴とする請求項3に記載の射出成形機。
