Claims (7)
- ロータ(12)の周辺に設けられた母形(14)に成形原料粉末(26)を充填し、ロータ(12)を制御速度(nr)に制御しながら回転して、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)に所定の下限値(PKlimit)以上のプレス力(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)の制御方法であって、
前記プレス力(PKactual)と下限値(PKlimit)が比較され、プレス力(PKactual)が前記下限値(PKlimit)未満であるときは、ロータ(12)の前記制御速度(nr)が定格速度(nr−rated)未満になるように減速制御して、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)の制御方法。 - 前記プレス力(PKactual)が測定される、請求項1に記載の制御方法。
- 前記下限値(PKlimit)とタブレットまたは類似のものの成形に必要なプレス力(PKrequired)の差を設定することができる、請求項1または2のいずれか一項に記載の制御方法。
- 前記差が1%と50%の間、好ましくは5%と20%の間であり、より好ましくは8%と12%の間である、請求項3に記載の制御方法。
- 前記ロータ(12)の前記制御速度(nr)と前記ロータ(12)の実際の速度が比較され、前記ロータ(12)が前記制御速度(nr)に調整される、請求項1から4のいずれか一項に記載の制御方法。
- 前記ロータ(12)が始動して定格速度(nr−rated)に至る過程で、前記減速制御が行われる、請求項1から5のいずれか一項に記載の制御方法。
- 前記ロータ(12)が定格速度(nr−rated)で回転しているとき、前記減速制御が行われる、請求項1から6のいずれか一項に記載の制御方法。
