Description
본 발명은 아연도금처리 설비에서 스트립(S)이 하부로 낙하되는 것을 방지하는 장치에 관한 것으로서, 보다 상세하게는 다수개의 센서를 보조 컴퓨터 및 중앙 컴퓨터에 연결하여 스트립(S)의 유, 무를 판단, 스트립을 고정하는 장치에 관한 것이다.The present invention relates to a device for preventing the strip (S) from falling to the bottom in the galvanizing treatment facility, more specifically, to determine the presence or absence of the strip (S) by connecting a plurality of sensors to the auxiliary computer and the central computer. And a device for fixing the strip.
도 1은 종래의 아연도금 처리 설비를 설명하기 위한 도면이고 도 2는 종래의 아연도금 처리 설비에서 스트립을 고정하기 위한 장치를 설명하는 도면이다.1 is a view for explaining a conventional galvanizing treatment facility and FIG. 2 is a view for explaining an apparatus for fixing a strip in a conventional galvanizing treatment facility.
도 1 내지 도 2를 참조하면, 일반적으로 아연도금처리설비는 아연도금조(110)를 스트립(S)이 통과하여 도금처리되는 PGI 강판과, 아연도금조(110)를 통과하지 않고 산세처리(picking and rinsing)되는 PO 강판을 생산한다.1 to 2, in general, the galvanizing treatment facility is a PGI steel plate which is plated by the strip S passing through the galvanizing bath 110, and pickling treatment without passing through the galvanizing bath 110 ( produce PO steel plate picking and rinsing).
상기 PGI 강판은 도 1에서 실선으로 도시된 바와 같이 아연도금조(110)를 통과하고 아연도금조(110)의 상부에서 에러나이프(120) 장치에 의해 스트립(S)에 부착된 아연 도금량이 조절된 다음, 그 상부에 웨치한 냉각 장치(130)를 상향 이동하면서 적정온도로 냉각된다.The PGI steel sheet passes through the galvanizing bath 110 as shown by the solid line in FIG. 1 and adjusts the amount of zinc plating attached to the strip S by the error knife 120 device at the top of the galvanizing bath 110. Then, it is cooled to an appropriate temperature while moving upwardly the cooling device 130 that has been wedged thereon.
그리고, 상부롤(140)과 핀치롤(140') 사이를 통과하여 도금량 측정장치(150)로 수평이동하고, 상기 도금량 측정장치(150)를 통과한 스트립(S)은 다시 상부롤(160)과 핀치롤(160') 사이를 통과하면서 하향되어 냉각장치(170)를 통과하게되며, 편향롤(180)을 거치면서 수평으로 이동하여 조질 압연 설비(미도시)로 이동된다.Then, the horizontal roll passes through the upper roll 140 and the pinch roll 140 'to the plating amount measuring device 150, and the strip S passing through the plating amount measuring device 150 is the upper roll 160 again. While passing between the pinch rolls 160 'and down to pass through the cooling device 170, and is moved horizontally while passing through the deflection roll 180 to the temper rolling equipment (not shown).
한편 PO 강판의 경우는, 도 1에서 점선으로 도시된 바와 같이 스트립(S)이 아연도금조(110)를 거치지 않고 산세설비(미도시)로부터 직접 조질 압연설비(미도시)로 이동하게 된다.Meanwhile, in the case of the PO steel sheet, as shown by the dotted line in FIG. 1, the strip S is moved directly from the pickling facility (not shown) to the temper rolling facility (not shown) without passing through the galvanizing bath 110.
따라서 PGI 강판과는 다른 제조과정을 거치게 되는 것이다.Therefore, the manufacturing process is different from the PGI steel sheet.
그러나 상기와 같은 아연도금처리설비에서 PGI 강판을 생산하는 도중에 PO 강판을 생산하기 위해 작업 방식을 변경하는 경우, 작업자는 두개의 상부롤(140)(160) 부근에 설치된 수동 고정장치(1)의 전기 판넬(35)을 조작하여 공기실린더(20)에 공기를 공급하게 한다.However, in the case of changing the working method to produce the PO steel sheet during the production of PGI steel sheet in the galvanizing treatment equipment as described above, the operator of the manual fixing device (1) installed near the two upper rolls 140, 160 The electric panel 35 is operated to supply air to the air cylinder 20.
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.As the actuating 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 closely fixes the strip S to the upper roll 140. do.
상기와 같이 고정판(25)이 스트립(S)을 지지한 상태에서 작업자는 편향롤(180) 부근에서 스트립(S)을 절단하고, PO 강판의 생산작업을 수행하게 된다.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.
한편, PO 강판의 생산작업이 완료되고, PGI 강판의 생산작업이 다시 실행되는 경우에는 상부롤(140)(160)과 마주하고 있는 핀치롤(140')(160')을 정회전시킴과 동시에 공기실린더(20)의 작동로드(20A)를 후진시키도록 전기판넬(35)을 가동시킨다.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, while simultaneously rotating the pinch rolls 140 'and 160' facing the upper rolls 140 and 160, The electric panel 35 is operated to reverse the operation rod 20A of the air cylinder 20.
따라서, 고정판(25)이 상부롤(140)으로부터 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, and the strip S is advanced due to the forward rotation of the pinch rolls 140 'and 160', thereby producing the PGI steel plate again.
상기와 같은 작업을 하는 이유는 도 1에 도시된 바와 같이 우측 상부롤(140)과 아연도금조(110)까지의 스트립(S) 길이가 좌측 상부롤(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.The reason for the above operation is that the length of the strip (S) to the right upper roll 140 and the galvanizing bath 110 as shown in Figure 1 to the left upper roll 160 and the deflection roll 180 Since the length of the strip S is significantly longer than the length of the strip S, the upper rolls 140 and 160 and the pinch rolls 140 'and 160' do not sufficiently stop the strip S by the force that fixes the strip S. This is to prevent the phenomenon (S) falls into the galvanizing bath (110).
그러나, 이러한 작업을 PO 및 PGI 강판 생산시에만 적용을 할 수 있으므로 PGI 강판 생산방식에서, 아연도금조(110)와 편향롤(180)사이의 스트립(S)이 작업도중 판파단이 발생하면 스트립(S)은 추락하고 장시간에 걸쳐 복구작업을 수행하게 되는 문제점이 있다.However, since this operation can be applied only in the production of PO and PGI steel sheets, in the PGI steel sheet production method, the strip S between the galvanizing bath 110 and the deflection roll 180 causes the strip to break during operation. (S) has a problem that fall and perform the recovery operation for a long time.
본 발명은 이와 같은 문제점을 해소하기 위한 것으로, PGI 강판 생산방식에서 PO 강판 생산방식으로 전환되는 경우에 스트립(S)의 추락을 방지할 수 있도록 하기 위한 새로운 형태의 스트립 낙하방지 장치를 제공하는 데 있다.The present invention is to solve such a problem, to provide a new type of strip fall prevention device for preventing the fall of the strip (S) when switching from PGI sheet production method to PO steel sheet production method. have.

이하 첨부된 도면을 참조하여 본 발명의 작용에 대하여 상세히 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail the operation of the present invention.
본 발명에서는 2가지 측면으로 설명을 하고자 하며, 첫번째 측면은 PGI 강판 생산방식에서 PO 강판 생산방식으로의 전환방법과, 두번째 측면은 PGI 강판 생산방식에서의 스트립 판파단 발생시의 제어 방법을 단계적으로 설명한다.In the present invention, it will be described in two aspects, the first aspect is a step-by-step description of the method of switching from the PGI steel sheet production method to the PO steel sheet production method, and the second aspect step by step the control method when the occurrence of strip breakage in the PGI steel sheet production method do.
첫번째 측면의 PGI 강판생산방식에서 PO 강판생산방식으로의 전환방법은 중앙컴퓨터(6)에 작업자가 생산방식 전환명령을 입력시키면, 중앙컴퓨터(6)는 명령을 인식하여 전기적인 신호를 전기판넬(35)에 보내어 고정장치(1)를 작동시키게 한다.In the first aspect of the PGI steel plate production method to PO steel plate production method, when the operator inputs a production method switching command to the central computer 6, the central computer 6 recognizes the command and sends an electrical signal to the electric panel ( 35) to activate the lock (1).
스트립 고정장치(1)의 작동이 완료되면 중앙컴퓨터(6)의 모니터에 생산방식 전환완료 화면이 생성되면 작업자는 생산방식전환을 기존의 수동방식에 입각하여 수행하게 된다.When the operation of the strip fixing device 1 is completed, when the production mode switch completion screen is generated on the monitor of the central computer 6, the operator performs the production mode switchover based on the existing manual method.
두번째 측면의 PGI 강판 생산방식에서의 스트립 판파단 발생시의 제어방법은 각각의 냉각장치(130)(170)사이에 설치된 센서(2) 및 텐션메타(7a)(7b)가 평상시 작업중에는 투광기(190)에서 보내는 빛을 수광기(200)가 받지 못하므로 감지를 하고 있는 상태이고, 또한 텐션메타(7a)(7b)는 스트립의 장력을 감지하고 있는데, PGI 강판의 판파단이 발생하면 다수개의 센서(2)중 어느 하나의 센서(2)가 투광기(190)에서 보내는 빛을 수광기(200)에서 감지를 하고, 또한 텐션메타(7a)(7b)에서 스트립의 장력을 측정하지 못하므로 상기 센서(2) 및 텐션메타(7a)(7b)는 감지 신호를 보조 컴퓨터(3, 4, 5)에 보내어진다.In the PGI steel sheet production method of the second aspect, the control method at the time of strip breaking occurs in each of the cooling devices 130 and 170, and the sensor 2 and the tension meter 7a and 7b are mounted on the light emitter 190 during normal operation. Since the light receiver 200 does not receive the light transmitted from the sensor), it is in a state of sensing, and the tension meters (7a) and (7b) detect the tension of the strip. Since any one of the sensors (2) (2) detects the light from the transmitter 190 in the receiver 200, and also does not measure the tension of the strip in the tension meter (7a) (7b) (2) and tension meters 7a and 7b send sensing signals to the auxiliary computers 3, 4 and 5.
상기 보조 컴퓨터(3, 4, 5)는 중앙 컴퓨터(6)로 판파단 신호를 보내고, 상기 중앙컴퓨터(6)는 판파단을 인식하여 전기적인 신호를 전기판넬(35)에 보내어 다수개의 스트립 고정장치(1)를 작동시켜 고정판(25)을 상부롤(160)에 협착이 되게하고, 하부에 있는 스트립 고정장치(1)는 상호 협착이 되게 한다.The secondary computer (3, 4, 5) sends a plate breaking signal to the central computer (6), the central computer (6) recognizes the plate breaking and sends an electrical signal to the electrical panel (35) to fix a plurality of strips The device 1 is operated to clamp the fixing plate 25 to the upper roll 160, and the lower strip fixing device 1 is to be stented to each other.
작동이 완료되면 작업자는 판파단 복구작업을 실시하고 중앙컴퓨터(6)에 판파단 복구 명령어를 삽입하여 스트립 고정장치(1)를 복구시키게 된다.When the operation is completed, the operator performs the plate breaking recovery operation and inserts the plate breaking command into the central computer 6 to restore the strip fixing device 1.
본 발명의 스트립 낙하방지 제어방법에 의하면, 다수개의 센서 및 텐션메타는 항시 스트립을 감지하고, 감지 신호를 항시 컴퓨터에 전송하고 있으므로, 다수개의 센서 및 텐션 메타중 어느 하나가 스트립을 감지하고 있지 않으면 즉시 컴퓨터에서 판파단 인식을 하여 스트립 고정장치를 작동시켜 대형설비사고를 미연에 방지할 수 있는 효과가 있다.According to the strip fall prevention control method of the present invention, since a plurality of sensors and tension meters always detect a strip and transmit a detection signal to a computer at all times, if any one of the plurality of sensors and tension meta is not detecting a strip, Immediately by detecting the break in the computer, it is possible to operate the strip fixing device to prevent the large equipment accident in advance.
