Abstract: 본 발명은 스텝피더, 턴테이블 등을 통해 공급되는 환봉 소재를 이송장치부에 공급하고, 소재의 공급 여부를 감지 및 카운터하면서 단조소재 자립위치 정렬기능을 갖도록 구성하여 단조작업 중 공급장치부에 의하여 단조소재를 연속적으로 공급할 수 있도록 한 단조소재 이송공급 장치에 관한 것이다.
이를 위해, 스텝피더와 이송장치부 사이에 공급장치부를 설치한 것에 있어서, 상기 공급장치부가, 모터에 회전 가능하게 결합되어 단조 소재를 공급받는 턴테이블과; 턴테이블의 테두리를 따라 설치된 커버플레이트와; 소재를 커버플레이트 내측면을 따라 정렬시키는 안내블레이드와; 정렬 상태의 소재를 배출하도록 커버플레이트 연결 설치된 안내슈트와; 안내슈트에 설치하여 소재를 슬라이딩시키는 슬라이딩슈트와; 슬라이딩슈트를 통해 공급되는 소재를 세워진 상태로 공급할 수 있게 기준플레이트에 설치한 홀딩수단과; 기준플레이트에 공급되는 소재를 클램핑하되, 제1핑거의 승강 이송을 제한하면서 전후 이송만이 가능하게 설치한 클램핑수단을 포함하는 것을 특징으로 한다.
상기한 구성에 따라, 슬라이딩슈트에서 공급되는 소재를 가이드부와 차단부가 사면에서 지지하므로, 길이가 긴 환봉형의 소재를 안정되게 세워 공급할 수 있고, 또한 슬라이딩슈트 상부에 소재의 잔량유무를 감지하고 공급수량을 카운터할 수 있는 감지센서를 설치하므로, 소재의 공급을 연속적으로 자동으로 조절할 수 있는 효과도 있다.
