일반적으로, 가열로에서 열처리되는 압연소재는 열간압연공정을 통해 일정두께로 압연된 상태에서 권취공정을 통해 코일형태로 감기는 과정까지 다단계의 압연공정 및 이송공정을 거치게 되는데, 이러한 압연소재는 압연공정 또는 이송공정의 과정에서 형상의 불량을 야기하게 된다. In general, the rolled material heat-treated in the furnace is subjected to a multi-stage rolling process and a transfer process from the rolled to a coil thickness in the state of being rolled to a certain thickness through the hot rolling process, the rolling material is rolled In the course of the process or the transfer process will cause a defect in the shape.

특히, 압연소재는, 그 선단부가 압연과정에서 롤러테이블이나 사이드가이드와 같은 주변기기와 간섭되는 경우 모서리부위가 파단되기도 하며, 또 롤러테이블상을 진행하는 과정에서 주행속도로 인해 날리는 경우 권취공정에서 겹쳐져 감겨지는 현상이 빈번하게 발생하게 된다. In particular, the rolled material, when the tip portion interferes with peripheral devices such as a roller table or side guide in the rolling process, the edge is broken, and when flying due to the running speed in the course of the roller table, it is overlapped in the winding process. The phenomenon of winding frequently occurs.

이때, 커팅부(30)의 토치부(33)는 상하한리미트스위치(미도시)에 의해 하강량 또는 상승량이 조절됨은 당연하다. 또, 토치부(33)에 뿜어져 나온 화염은 와인더부(10)의 내벽에 코팅되어진 세라믹(15)에 의해 열전달이 방지되는 것이다. At this time, the torch portion 33 of the cutting unit 30 is naturally lowered or raised amount is controlled by the upper and lower limit switches (not shown). In addition, the flame sprayed on the torch part 33 is to prevent heat transfer by the ceramic 15 coated on the inner wall of the winder part 10.

이어서, 절단장치(1)에 의해 제거되어진 불량부(110)가 와인더부(10)의 자력에 의해 부착된 상태에서, 실린더(43)의 작동과정에서 권취코일(100)의 내권부로부터 인출되어 스크랩박스(미도시)로 옮겨져 제거된다.Subsequently, in the state where the defective part 110 removed by the cutting device 1 is attached by the magnetic force of the winder part 10, it is withdrawn from the inner winding part of the winding coil 100 during the operation of the cylinder 43. It is transferred to a scrap box (not shown) and removed.

물론, 와인더부(10)는, 냉각수배출홀(22)을 통해 분사되는 냉각수에 의해 지속적으로 냉각되는 상태이므로, 권취코일(100)이나 토치부(33)에 의해 발생되는 열에 의한 자력상실이 방지된다. Of course, since the winder unit 10 is continuously cooled by the coolant injected through the coolant discharge hole 22, the magnetic force loss due to the heat generated by the winding coil 100 or the torch unit 33 is prevented. do.

이후, 불량부(110)가 제거되어진 권취코일(100)은 컨베이어(120)상에 구비되어있던 평량기(140)에 의해 중량이 측정된 후 검사공정 및 결속공정을 통해 보관장소로 이송되는 것이다. Thereafter, the winding coil 100 from which the defective part 110 is removed is weighed by the weighing machine 140 provided on the conveyor 120 and then transferred to a storage place through an inspection process and a binding process. .

이상에서 설명한 바와 같이 본 발명에 따른 박물열연코일 선단부의 불량부 제거 장치에 의하면, 귄취코일의 선단부에 형성되어진 불량부의 절단작업이 권취상태이서도 가능해지므로 권취코일을 원상태로 풀어서 절단하는 정정공정이 삭제되어 작업공수를 단축시킴은 물론 이로인해 제반 부대비용이 절감될 뿐만 아니라, 귄취코일의 정정공정에서 발생하는 표면결함이 원천봉쇄되므로 제품이 품질이 일정하게 유지되어 가격 경쟁력이 향상되는 효과가 있는 것이다.  As described above, according to the apparatus for removing the defective portion of the tip portion of the thin hot rolled coil according to the present invention, since the cutting operation of the defective portion formed at the tip of the winding coil can be performed even in a wound state, a correction process for unwinding the winding coil and cutting This not only shortens the labor but also reduces the overall costs, and also blocks the surface defects generated during the correction process of the GUNZU coil so that the quality of the product is kept constant, which improves the price competitiveness. will be.
