Claims (4)

  1. 계량공정에 있어서, 스크루를 축방향으로 이동시키기 위한 서보모터를 오우버라이드치와 수치제어프로그램에서 지정한 회전 속도를 합한 값과 동일한 목표회전속도로 스크루 후퇴방향으로 회전시키는 공정(a)과, 검출한 실제수지압력이 미리 설정한 목표 배압이 되도록 상기 공정 (a)에서 사용하는 상기 오우버 라이드치를 변화시키는 공정 (b)을 갖룬 전동식 사출성형기의 배압제어방법.
  2. 제1항에 있어서, 상기 공정 (b)에서 상기 오우버라이드치를 그 변화에 수반하여 상기 목표회전속도에 활연속적 변화가 발생하지 않게 하는 변화율로 변화시키는 전동식 사출 성형기의 배압제어방법.
  3. 스크류를 축방향으로 이동시키기 위한 서보모떠를 가지는 전동켁 사출 성형기에 있어서 목표배압을 설정하기 위한 설정수단과, 상기 사출 성형기의 계량공정에 있어서 오우버라이드치와 수치제어프로그램에서 지정한 회전속도를 할한 값과 동일한 목표회전속도로 상기 서보모터를 스크루 후퇴 방향으로 회전시키기 위한 모터 구동수단과, 실제 수지 압력을 검출하기 위한 압력검을수단과, 상기 검출실제 수지압력과 상기 목표배압율 비교하기 위한 비교수단과, 상기 비교 수단에 의한 비교결과에 따라서 상기 오우버라이드치를 변화시키기 위한 조정수단을 구비한 것을 특징으로 하는 전동식 사출 성령기의 배압제어장치.
  4. 제3항에 있어서, 상기 조정수단은 상기 비교 결과에 따라 상기 오우버라이드치를 그 변화에 수반하여 상기 목표 회전 속도에 불연속적 변화가 발생하지 않게하는 변화율로 변화시키는 전동식 사출 성형기의 배압제어 장치.
