Claims (1)
- ロータ(12)の周辺に設けられた母型(14)に成形原料粉末(26)を充填し、ロータ(12)を回転して、この回転に伴い母型(14)がプレス・ステーション(28)に達すると一対の圧縮ローラ(30)が上下のパンチ(18)、(16)と対面接触して、これらを押すことにより、上下のパンチ(18)、(16)が母型(14)内に突入し、前記成形原料粉末(26)にプレス力(PKactual)を印加して、タブレットまたは類似のものにプレスするとともに、前記対面接触により上下のパンチ(18)、(16)が一対の圧縮ローラ(30)を回転駆動するロータリータブレット成形機(10)の制御装置であって、
前記ロータ(12)の駆動ユニット(24)を制御する制御ユニット(42)と、
前記プレス力(PKactual)を測定するプレス力測定手段(40)と、
前記測定されたプレス力(PKactual)と予め設定されたプレス力下限値(PKlimit)を比較する比較手段と、
前記ロータ(12)の所要制御速度(nr)を予め設定して、この設定した所要制御速度(nr)の信号を前記制御ユニット(42)に送る速度設定手段と
を備え、
プレス力(PKactual)がプレス力下限値(PKlimit)よりも小さいとき、ロータ(12)の所要制御速度(nr)を定格速度(nr−rated)未満にして、ロータ(12)よりも遅く回転する圧縮ローラ(30)とロータ(12)の回転速度で回転する上下のパンチ(18)、(16)との対面接触の衝撃を弱めることを特徴とするロータリータブレット成形機(10)の制御装置。
