본 고안은 아연도금처리 설비에서 스트립(Strip)이 하부로 낙하되는 것을 방지하기 위한 장치에 관한 것으로, 보다 상세히는 공기 실린더에 의해 전, 후진되는 고정판을 상부롤에 밀착시켜 그사이에 스트립을 협착 고정함으로서 돌발적인 추락에 의한 안전사고를 예방하도록 된 스트립 낙하방지 장치에 관한 것이다.The present invention relates to a device for preventing a strip from falling down in a galvanizing treatment facility, and more particularly, the fixing plate forward and backward by an air cylinder is in close contact with the upper roll to clamp the strip in between. The present invention relates to a strip fall prevention device configured to prevent a safety accident caused by an accidental fall.
일반적으로 아연도금처리설비(100)는 아연도금조(110)를 스트립(S)이 통과하여 도금처리되는 PGI 강판과, 아연도금조(110)를 통과하지 않고 산세처리(Pickling and Rinsing)되는 PO강판을 생산한다. 상기 PGI강판은 제3도에서 실선으로 도시된 바와같이 아연도금조(110)를 스트립(S)이 통과하고, 아연도금조(110)의 상부에서 에어나이프(Air Knife) 장치(120)에 의해 스트립(S)에 부착된 아연 도금량이 조절된 다음, 그 상부에 위치한 냉각장치(130)를 상향이동하면서 적정온도로 냉각된다. 그리고, 상부롤(Top roll)(140)과 핀치롤(Pinch roll)(140')사이를 통과하여 도금량 측정장치(Coating Weight Gauge)(150)로 수평이동하고, 상기 도금량 측정장치(150)를 통과한 스트립(S)은 다시 상부롤(160)과 핀치롤(160') 사이를 통과하면서 하향되어 냉각장치(170)를 통과하게 되며, 편향롤(180)을 거치면서 수평으로 이동하여 조질압연설비(Skin Pass Mill)(미도시)로 이동된다. 한편, PO 강판의 경우는, 제3도에서 점선으로 도시된 바와같이 스트립(S)이 아연도금조(110)를 거치지 않고, 산세설비(미도시)로 부터 직접 조질압연설비(미도시)를 이동하게 된다.In general, the galvanizing treatment facility 100 is a PGI steel plate plated by the strip S passing through the galvanizing bath 110, and PO which is pickled and rinsed without passing through the galvanizing bath 110. Produce steel sheet. The PGI steel sheet is a strip (S) passes through the galvanizing bath 110, as shown by the solid line in Figure 3, by the air knife (Air Knife) device 120 at the top of the galvanizing bath 110 The amount of zinc plating attached to the strip S is adjusted, and then cooled to an appropriate temperature while moving upwardly the cooling device 130 located above. Then, the horizontal roll is moved horizontally to the coating weight gauge 150 through the top roll 140 and the pinch roll 140 ', and the plating amount measuring device 150 is moved. The strip S passed again passes downward between the upper roll 160 and the pinch roll 160 ′ and passes through the cooling device 170. The strip S moves horizontally while passing through the deflection roll 180 to perform temper rolling. Moved to a facility (Skin Pass Mill) (not shown). On the other hand, in the case of PO steel sheet, as shown by the dotted line in Figure 3, the strip (S) does not go through the galvanizing bath 110, the crude rolling equipment (not shown) directly from the pickling equipment (not shown) Will move.
따라서, PGI 강판과는 다른 제조과정을 거치게 되는 것이다. 그러나, 상기와같은 아연도금처리설비에서 PGI 강판을 생산하는 도중에 PO강판을 생산하기 위해 작업 방식을 변경하는 경우, 작업자는 편향롤(180) 부근에서 PGI 강판을 절단하고, 아연도금조(110)의 전방에서 PGI강판을 절단한 다음, 편향롤(180) 부근의 PGI 강판단부에 구멍을 형성시켜 철선(wire) (W)으로 인접한 기둥(support)(190)에 고정시키는 것이었다. 그리고 스트립(S)을아연도금조(110)로 진입시키지 않고, 우회시켜 조질압연설비를 이동시킴으로서 PO 강판을 생산하게 된다. 상기 과정에서 작업자가 편향롤(180)부근에서 PGI 강판의 단부를 인접한 기둥에 철선으로서 고정하는 이유는, 제3도에 도시된 바와같이 우측 상부롤(140)과 아연도금조(110)까지의 스트립(S)길이가 좌측상부롤(160)과 편향롤(180)까지의 스트립(S) 길이보다 현저히 길기 때문에, 상기 상부롤(140)(160)과 핀치롤(140')(160')이 스트립(S)을 고정하는 힘만으로는 충분히 스트립(S)을 정지시키지 못하여 스트립(S)이 아연도금조(110)로 추락하는 현상을 방지하기 위해서이다. 그러나, 이러한 작업은 매우 번거로운 것이었고, 또한 작업자가 실수로 견고하게 스트립(S)을 고정시키지 못하는 경우는 스트립 추락으로 인하여 대형 안전사고가 초래될 위험성이 항상 크게 내포된 것이었다.Therefore, the manufacturing process is different from the PGI steel sheet. However, in the case of changing the working method to produce the PO steel sheet during the production of the PGI sheet in the galvanizing treatment equipment as described above, the operator cuts the PGI sheet in the vicinity of the deflection roll 180, the galvanizing tank 110 After cutting the PGI steel sheet in front of the PGI steel sheet, a hole was formed in the end portion of the PGI steel sheet near the deflection roll 180, and then fixed to the adjacent support (190) with a wire (W). In addition, the strip S does not enter the zinc plating tank 110, but bypasses and moves the temper rolling equipment to produce the PO steel sheet. In the above process, the operator fixes the end of the PGI steel sheet to the adjacent pillar near the deflection roll 180 as an iron wire, as shown in FIG. 3, to the right upper roll 140 and the galvanizing bath 110. Since the length of the strip S is significantly longer than the length of the strip S to the upper left roll 160 and the deflection roll 180, the upper rolls 140, 160 and the pinch rolls 140 'and 160'. This is to prevent the phenomenon that the strip S falls into the galvanizing bath 110 by not enough stopping the strip S by the force for fixing the strip S alone. However, this work was very cumbersome, and if the operator could not securely fix the strip S by mistake, there was always a great risk of a large safety accident due to the fall of the strip.
본 고안은 상기와 같은 문제점을 해소하기 위하여 안출된 것으로서, PGI 강판 생산방식에서 PO 강판 생산방식으로 전환되어 PGI 강판이 절단되는 경우, 매우 간편하게 또한 안전하게 스트립의 추락을 방지할수 있는 스트립 낙하방지 장치를 제공함에 그 목적이 있다.The present invention was devised to solve the above problems, when the PGI steel sheet is cut from the PGI steel sheet production method to the production method of the PGI steel sheet is cut, the strip fall prevention device that can prevent the fall of the strip very easily and safely.

On the other hand, the air cylinder 20 is connected to the solenoid control valve 34 which is electrically operated by extending the air supply pipe (31a) (31b) to the outside of the rectangular case 12, respectively. The solenoid control valve 34 is selectively operated to supply air to one of the air supply pipes 31a and 31b by a switch operation of the electric panel 35.
상기와 같이 구성된 본 고안은 PGI 강판 생산 방식에서 PO 강판 생산방식으로 전환되는 경우, PGI 강판을 절단하기 전에 공기실린더(20)에 공기가 공급된다.When the present invention configured as described above is switched from the PGI steel sheet production method to the PO steel sheet production method, air is supplied to the air cylinder 20 before cutting the PGI steel sheet.
공기실린더(20)의 작동로드(20a)가 전진함에 따라서 고정판(25)은 상부롤(140)측으로 전진하게 되고, 고정판(25)이 스트립(S)을 상부롤(140)에 밀착시켜 고정시키게 된다. 이때 안내부재(26a)(26b)는 고정판(25)과 함께 전진하게 되고, 고정판(25)이 수평으로 이동하도록 안내한다. 상기와 같이 고정판(25)이 스트립(S)을 지지한 상태에서 작업자는 편향롤(180)부근에서 스트립(S)을 절단하고, PO강판의 생산작업을 수행하게 된다. 한편, PO강판의 생산작업이 완료되고, PGI 강판의 생산작업이 다시 실행되는 경우에는, 상부롤(140)(160)과 마주하고 있는 핀치롤(140')(160')을 정회전 시킴과 동시에 공기실린더(20)의 작동 로드(20a)를 후진시키도록 전기 판넬(35)을 가동시킨다.As the working rod 20a of the air cylinder 20 is advanced, the fixing plate 25 is advanced toward the upper roll 140, and the fixing plate 25 is fixed to the upper roll 140 by bringing the strip S into close contact. do. At this time, the guide members 26a and 26b are advanced together with the fixed plate 25 and guide the fixed plate 25 to move horizontally. In the state in which the fixing plate 25 supports the strip S as described above, the worker cuts the strip S near the deflection roll 180 and performs a production operation of the PO steel sheet. On the other hand, when the production operation of the PO steel sheet is completed, and the production operation of the PGI steel sheet is executed again, the pinch rolls 140 'and 160' facing the upper rolls 140 and 160 are rotated forward and At the same time, the electric panel 35 is operated to reverse the working rod 20a of the air cylinder 20.
따라서, 고정판(25)이 상부롤(140)로 부터 멀어지게 되고, 스트립(S)은 핀치롤(140')(160')의 정회전으로 인하여 전진함으로서 다시 PGI 강판의 생산작업이 진행된다.Therefore, the fixing plate 25 is moved away from the upper roll 140, the strip (S) is advanced by the forward rotation of the pinch rolls (140 ', 160') and the production operation of the PGI steel sheet is again in progress.
상기에서와 같이 본 고안에 의하면, PGI 강판생산 방식에서 PO강판 생산방식으로 전환되어 스트립(S)을 절단하는 경우, 별도로 작업자가 편향롤(180)의 부근에서 철선으로 스트립(S)을 고정하는 번거로움이 해소되며, 스트립(S)을 고정하기 위해서 전기판넬(35)을 동작시키기만 하면되기 때문에 작업이 매우 간단하게 이루어진다. 또한 공기의 압력을 이용하여 고정판(25)이 상부롤(140)과의 사이에서 스트립(S)을 협착, 고정하기 때문에 안전하게 스트립(S)은 지지할수 있게 되어 안전사고가 예방되며, PO 강판 생산 방식에서 PGI 강판 생산방식으로 전환시 작업시간이 단축됨으로써 작업생산성이 향상되는 실용상의 효과가 얻어지게 된다.According to the present invention as described above, when cutting the strip (S) by switching from the PGI sheet production method to the PO steel sheet production method, the operator separately to fix the strip (S) with the iron wire in the vicinity of the deflection roll (180) The hassle is eliminated, and the operation is very simple because only the electric panel 35 is operated to fix the strip S. In addition, since the fixing plate 25 clamps and fixes the strip S between the upper rolls 140 using air pressure, the strip S can be securely supported to prevent safety accidents. When switching from the method to the PGI steel plate production method, the working time is shortened, thereby obtaining a practical effect of improving work productivity.
