본 발명은 코팅설비의 코팅불량 방지장치에 관한 것으로, 보다 상세하게는 절연코팅시 코팅롤 막힘현상에 의해 유발되는 코팅 결함을 방지할 수 있도록 개선된 코팅설비의 코팅불량 방지장치에 관한 것이다.The present invention relates to a coating failure prevention apparatus of the coating equipment, and more particularly to a coating failure prevention apparatus of the improved coating equipment to prevent coating defects caused by the clogging of the coating roll during the insulation coating.

일반적으로, 각종 모터, 발전기, 안전기 등과 같은 전기기기용 철심으로 사용되는 무방향성 전기강판은, 와전류 발생에 따른 전력손실을 최소화하기 위하여 그 표면에 절연피막이 코팅된다.In general, the non-oriented electrical steel sheet used as iron cores for electric devices such as various motors, generators, safety devices, etc., is coated with an insulating coating on the surface of the sheet to minimize the power loss caused by eddy currents.

이러한 절연피막용으로 사용되는 코팅용액은 주로 MgO가 사용된다.MgO is mainly used as a coating solution for such an insulating coating.

예컨대, 두께 0.262~0.350mm를 갖는 박판 스트립은 소둔 및 탈탄된 후 그 상,하면에 MgO 용액이 도포되게 된다.For example, a thin strip having a thickness of 0.262 to 0.350 mm is annealed and decarburized, and then MgO solution is applied to the upper and lower surfaces thereof.

도포 방식은 도 1a의 예시와 같이, 스트립(S)의 상부면에는 스프레이노즐(1)에 의해 1차 도포되고, 이어 표면에 그루브(홈)가 형성된 상부링거롤(2)을 통해 2차 도포되게 된다.1A is applied to the top surface of the strip (S) by the spray nozzle (1), as shown in Figure 1a, the second coating through the upper ringer roll (2) formed with a groove (groove) on the surface. Will be.

그리고, 스트립(S)의 하부면에는 하부링거롤(3)이 코팅용액팬(4)으로부터 코팅용액을 픽업하여 도포하게 된다.Then, the lower ringer roll (3) to the lower surface of the strip (S) to pick up and apply the coating solution from the coating solution fan (4).

그런데, 상기 상부링거롤(2) 및 하부링거롤(3)을 통과하는 스트립(S)에 구멍이 생겼다든지 혹은 MgO 수용액내 고형물이 잔존하여 이것이 함께 픽업되었다든지 내지 스트립(S)을 연결하기 위해 용접한 부분이 통과한다든지와 같은 원인으로 인하여 도포불가, 도포면 불균일, 기포에 의한 도포불량 등의 문제가 유발되고 있다.However, a hole is formed in the strip S passing through the upper ringer roll 2 and the lower ringer roll 3, or solids remain in the MgO aqueous solution so that it is picked up together to connect the strip S. Problems such as coating failure, coating surface irregularity, coating failure due to bubbles, etc. are caused due to the cause such as passage of the welded portion.

이를 테면, 도 1b에서와 같이, 도포면에 줄무늬 형상의 결함(5)이 발생되는 것이 그것인데, 이러한 현상은 지속적이고 연속적으로 일어나게 되어 있어 그 피해가 극심하다.For example, as shown in FIG. 1B, a stripe defect 5 is generated on the coated surface, and this phenomenon occurs continuously and continuously, and the damage is severe.

특히, 고형분에 의한 하부링거롤(3)의 그루부(홈) 막힘 현상은 더욱 더 큰 피해를 초래하게 된다.In particular, clogging of the grooves (grooves) of the lower ringer roll 3 due to solid content causes more and more damage.

이는 하부링거롤(3)이 상부링거롤(2)과는 달리 코팅용액팬(4)에 직접 침지된 상태에서 코팅용액을 픽업하는 형태로 설치되기 때문이다.This is because the lower ringer roll 3 is installed in the form of picking up the coating solution in a state where the upper ringer roll 2 is directly immersed in the coating solution fan 4.

본 발명은 상술한 바와 같은 종래 기술상의 한계점을 감안하여 이를 해결하고자 창출한 것으로, 합성섬유로 된 브러쉬와 스펀지를 이용하여 링거롤의 그루부 막힘을 방지하여 균일하고 일정한 두께의 도포면을 형성할 수 있도록 하여 특히 하부링거롤에서 발생되는 줄무늬 결함을 방지함으로써 코팅품위를 향상시키고, 제조비용도 절감시킬 수 있도록 한 코팅설비의 코팅불량 방지장치를 제공함에 그 주된 목적이 있다.The present invention was created in view of the limitations of the prior art as described above, to solve this problem, by using a brush and sponge made of synthetic fibers to prevent clogging of the ringer roll to form a uniform and uniform thickness coated surface.

상기 고정봉(120)은 스트립(S)의 폭방향으로 가로질러 설치된다.The fixing rod 120 is installed across the width direction of the strip (S).

아울러, 상기 고정봉(120)에는 상기 하부링거롤(100)의 곡률반경에 대응되는 곡률을 갖는 보호커버(130)가 고정된다.In addition, a protective cover 130 having a curvature corresponding to the radius of curvature of the lower ringer roll 100 is fixed to the fixing rod 120.

상기 보호커버(130)는 도 4의 도시와 같이, 그 양단에는 수납부(132)가 형성되고, 길이방향으로 수납부(132)를 제외한 부분에는 절개부(134)가 형성되는 바, 이는 코팅용액팬과의 간섭을 피하기 위한 것이다.The protective cover 130, as shown in Figure 4, both ends of the receiving portion 132 is formed, a portion 134 is formed in the cut portion 134 in the longitudinal direction except the receiving portion 132, which is coated This is to avoid interference with the solution pan.

또한, 상기 보호커버(130)의 수납부(132)는 그 외면이 상기 지지블럭(110)상에 안착된 구조를 가짐이 바람직하다.In addition, the accommodating part 132 of the protective cover 130 preferably has a structure in which an outer surface thereof is seated on the support block 110.

이를 위해, 상기 지지블럭(110)의 일부에는 그와 대응되는 요홈이 가공되어야 할 것이다.To this end, a portion of the support block 110 will have to be processed grooves corresponding thereto.

그리고, 상기 보호커버(130)와 하부링거롤(100) 사이에는 브러쉬(140)가 설 치된다.Then, the brush 140 is installed between the protective cover 130 and the lower ringer roll 100.

상기 브러쉬(140)는 합성섬유로 형성됨이 바람직하고, 상기 보호커버(130)의 수납부(132)의 폭만큼의 크기로 형성되어 하부링거롤(100)의 길이에 대응되게 설치된다.The brush 140 is preferably formed of synthetic fibers, is formed in the size of the width of the receiving portion 132 of the protective cover 130 is installed to correspond to the length of the lower ringer roll (100).

따라서, 상기 하부링거롤(100)이 코팅용액을 픽업하는데는 전혀 지장이 없게 된다.Therefore, the lower ringer roll 100 is no problem to pick up the coating solution.

한편, 상기 하부링거롤(100)의 전방, 다시말해 고정봉(120)의 대향측에는 유동흡입통(150)이 설치된다.On the other hand, the front of the lower ringer roll 100, that is, the flow suction cylinder 150 is installed on the opposite side of the fixing rod 120.

또한, 상기 유동흡입통(150)과 하부링거롤(100) 사이에는 스펀지(160)가 개재된다.In addition, a sponge 160 is interposed between the flow suction tube 150 and the lower ringer roll 100.

상기 스펀지(160)도 하부링거롤(100)의 픽업을 방해하지 않도록 하부링거롤(100)의 외주면중 하측이 아닌 측방에만 설치됨이 바람직하다.The sponge 160 is also preferably installed only on the side of the outer peripheral surface of the lower ringer roll 100, not the lower side so as not to interfere with the pickup of the lower ringer roll 100.

그리고, 상기 스펀지(160)는 상기 유동흡입통(150)에 완전히 밀착고정되면서 상기 하부링거롤(100)에도 접촉되는 형태로 배치되어 하부링거롤(100)의 회전시에도 이탈됨없이 위치고정되게 설치된다.In addition, the sponge 160 is arranged in contact with the lower ringer roll 100 while being completely fixed to the flow suction cylinder 150 so that the sponge 160 is fixed without being separated even when the lower ringer roll 100 rotates. Is installed.

아울러, 상기 유동흡입통(150)은 대략 긴 사각통형상으로 형성되며, 그 상단면은 개방된 형태로 형성된다.In addition, the flow suction cylinder 150 is formed in a substantially long rectangular cylinder shape, the top surface is formed in an open shape.

또한, 그 전면 일부에는 그와 연통되는 드레인관(170)이 연결설치된다.In addition, a drain pipe 170 connected to the front part is installed.

상기 드레인관(170)은 대략 얇은 사각판상의 통체로서 그 길이 일부는 주름부(172)가 마련되어 신축가능하게 구성된다.The drain pipe 170 is a substantially thin rectangular plate-like cylinder, and part of the length thereof is provided with a pleat portion 172 to be configured to be elastic.

뿐만 아니라, 상기 유동흡입통(150)의 하단은 유동실린더(180)에 연결되고, 상기 유동실린더(180)는 상기 지지블럭(110)의 전면에 고정된다.In addition, the lower end of the flow suction cylinder 150 is connected to the flow cylinder 180, the flow cylinder 180 is fixed to the front of the support block 110.

또한, 상기 유동흡입통(150)의 하단에는 연결브라켓(190)가 연장형성되고, 그 단부는 하부링거롤(100)의 회전축(102)에 연결고정된다.In addition, the lower end of the flow suction tube 150, the connecting bracket 190 is extended, the end is connected to the rotating shaft 102 of the lower ringer roll 100 is fixed.

이때, 상기 연결브라켓(190)은 상기 회전축(102)의 회전과 무관하게 자체 회전유동성을 갖도록 베어링고정된다.In this case, the connection bracket 190 is fixed to have a rotational fluidity of its own regardless of the rotation of the rotary shaft 102.

그리고, 상기 연결브라켓(190)의 길이 일부에는 장공(192)이 형성되고, 상기 장공(192)에는 상기 보호커버(130)의 수납부(132)에 돌출형성된 안내돌기(136)가 끼워진다.In addition, a long hole 192 is formed in a part of the length of the connection bracket 190, and the guide protrusion 136 protruding from the receiving part 132 of the protective cover 130 is fitted into the long hole 192.

따라서, 상기 유동실린더(180)의 전후진동작에 따라 상기 유동흡입통(150)은 상기 장공(192)의 범위내에서 회전유동하게 된다.Therefore, the flow suction cylinder 150 rotates in the range of the long hole 192 according to the forward and backward motion of the flow cylinder 180.

이러한 구성으로 이루어진 본 발명의 작동관계는 다음과 같다.The operating relationship of the present invention made of such a configuration is as follows.

하부링거롤(100)은 종래와 동일한 방식으로 코팅용액팬에 수용된 코팅용액인 MgO 수용액에 침지된 상태를 유지하면서 회전하게 되어 결국 코팅용액을 묻혀(픽업) 스트립의 하단면에 도포하게 된다.The lower ringer roll 100 is rotated while being immersed in the MgO aqueous solution, which is a coating solution accommodated in the coating solution pan, in the same manner as in the prior art, and is finally coated with the coating solution (pickup) to be applied to the bottom surface of the strip.

이때, 유동실린더(180)는 설정된 상태에 따라 주기적 혹은 간헐적 또는 수시로 동작하게 된다.At this time, the flow cylinder 180 operates periodically or intermittently or from time to time according to the set state.

만약, 픽업되는 코팅용액중 MgO 덩어리가 하부링거롤(100)의 그루브에 낀 상태로 픽업되면 브러쉬(140)에 의해 걸러지면서 탈거되게 된다.If the MgO mass in the coating solution to be picked up is caught in the groove of the lower ringer roll 100, it is removed by being filtered by the brush 140.

따라서, 픽업되는 코팅용액은 균일하게 픽업되어 스트립의 하면에 코팅하게 된다.Therefore, the coating solution to be picked up is uniformly picked up and coated on the lower surface of the strip.

이후, 코팅액이 과다할 경우에는 일부 남은 코팅액이 스펀지(160)에 의해 닦여지면서 넘쳐 유동흡입통(150)으로 유입되고, 유입된 잔여 코팅액은 드레인관(170)으로 흡입되어 배출되게 된다.Subsequently, when the coating liquid is excessive, some remaining coating liquid is wiped by the sponge 160 and overflows into the flow suction tube 150, and the remaining coating liquid is sucked into the drain pipe 170 and discharged.

또한, 유동실린더(180)에 의해 스펀지(160)가 밀착과 문지름을 반복하면서 그루브에 잔류되는 또다른 이물들을 완전히 제거하게 된다.In addition, the sponge 160 by the flow cylinder 180 is to remove the other foreign matter remaining in the groove while repeating the contact and rub repeatedly.

이에 따라, 코팅액은 균일하게 도포되게 되면 이물 제거에 따라 줄무늬와 같은 결함이 방지되게 된다.Accordingly, when the coating liquid is uniformly applied, defects such as streaks are prevented as the foreign material is removed.
