Claims (5)

  1. 플라스틱(13)을 공급하는 압출기에 연결되며, 충만한 상태에서 패리슨을 생성하도록 방출 피스톤(4)이환형 슬릿 형상의 방출 개구를 통해 플라스틱을 방출하게 되는 축압기 헤드(1)와, 패리슨으로부터 중공형 제품을 형성하기 위한 취입 주형과, 취입 서영 연속 공정이 완료된 후에 미리 나열된 속도 고정점 프로필로 부터의 통합에 의해 결정되는 방출 피스톤(4)의 고정 위치와 실제 위치 사이의 차이에 의해 형성된 비교 신호로부터 방출 피스톤의 위치를 조정하기 위한 피스톤 위치 지정신호를 발하는 조절 장치를 구비하는 중공형 취입 성형기에 있어서, 조절 장치(15)는, 방출된 축압기 헤드(1)의 용량을 교체시키도록 압출기(2)로부터 유입되는 플라스틱의 용적 변화에 상응하는 유입 신호를 비교 신호에 첨가하고, 압출기의 회전 속도를 조정함으로써 방출공정 말기에 축압기 헤드에 플라스틱이 남아 잇도록 하는 고정점 쿠션과 실제 쿠션 사이의 편차를 감소시키는 것을 특징으로 하는 취입 성형기.
  2. 제1항에 있어서, 조절 장치(15)는, 최종 위치를 위한 고정점 값으로부터 방출 공정 말기에 측정된 유입 신호값을 공제함으로써 작동 쿠션을 얻고, 고정점 쿠션과 실제 쿠션 사이에 응차 신호를 형성하고, 압출작동기(3)가 회전 속도를 맞추도록 미분 및 통합에 의해 응차 신호로부터 회전 속도 고정점 신호를 생성하는 것을 특징으로 하는 취입 성형기.
  3. 제2항에 있어서, 조절 장치(15)는 통합에 의해 회전 속도 고정점 신호로부터 유입 신호를 형성하는 것을 특징으로 하는 취입 성형기.
  4. 제3항에 있어서, 피스톤 작동기(19)는 방출 피스톤의 위치를 조정하는 피스톤 위치 지정 신호에 의존하는 방출 피스톤(4)의 위치를 정하고, 압출기(2)로부터 축압기 헤드(1)를 채움으로써 최종 위치를 위한 고정점값에 도달한 후에 조절 장치로부터의 재고정 신호에 의해 방출 피스톤을 초기 위치로 복귀시키는 것을 특징으로 하는 취입 성형기.
  5. 제2항 내지 제4항중 어느 한 항에 있어서, 조절 장치(15)는 비교 단계(28)에서 형성된 응차 신호로부터 압출 작동기(3)를 위한 회전 속도 고정점 신호를 생성하는 응차 통합 조정기(34)를 구비하는 것을 특징으로 하는 취입 성형기.
