Description

컨덕터롤 밴드마크 방지장치{DEVICE FOR PREVENTING CONDUCTOR ROLL BAND MARK}Conductor band mark prevention device {DEVICE FOR PREVENTING CONDUCTOR ROLL BAND MARK}

본 발명은 컨덕터롤 밴드마크 방지장치에 관한 것으로, 보다 상세하게는 전기도금용 콘턱터롤의 밴드와 러버가 접하는 부분의 단차를 줄여 스트립이 이동접촉시 징크트리(아연가루)와 밴드에 의한 자국발생을 방지할 수 있도록 한 컨덕터롤 밴드마크 방지장치에 관한 것이다.The present invention relates to a band roll preventing device of the conductor roll, and more particularly, to reduce the step difference between the band and the rubber contact portion of the electroplating conductor roll, the strip generated by the zinc tree (zinc powder) and the band during the mobile contact. The present invention relates to a bandroll prevention device for conductor rolls.

일반적으로 전기도금 작업시 컨덕터롤(CONDUCTOR ROLL) 표면의 밴드와 러버(RUBBER)와의 단차를 0.15~0.5mm 정도 유지하고 있다.In general, during electroplating, the step between the band on the surface of the conductor roll and the rubber is maintained at 0.15 ~ 0.5mm.

이는 단차가 없을 경우에 컨덕터롤 밴드에서 스트립에 전달되는 음극전류가 일정하지 못하고 스트립에 발생되는 스폿(SPOT)으로 인하여 전기도금작업이 어려울 뿐만 아니라 제품의 품질불량을 초래하기 때문이다.This is because when there is no step, the cathode current transmitted from the conductor roll band to the strip is not constant, and the spot (SPOT) generated in the strip is not only difficult for electroplating but also causes a poor quality of the product.

반면에, 상기와 같이 단차를 유지하고 있을 경우에는 도 1의 도시와 같이, 컨덕터롤(1)과 굴절롤(3)에 의해 도금조(4)를 거쳐 이동되는 스트립(2)의 표면에 그 길이방향으로 밴드마크(5)가 발생하게 된다.On the other hand, when the step is maintained as described above, as shown in FIG. 1, the surface of the strip 2 moved through the plating bath 4 by the conductor roll 1 and the refraction roll 3 is applied to the surface of the strip 2. The band mark 5 is generated in the longitudinal direction.

이는 도 2의 도시와 같이, 전기한 컨덕터롤(1)에 음전류를 공급하도록 그 외주연에 일정폭 권취되어 있는 컨덕터롤(1) 중앙부의 밴드(7)와 상기 밴드(7)를 제외한 컨덕터롤(1) 양단부측의 러버(8)와의 단차(T)진 공간사이로 컨덕터롤(1)과 스트립(2)이 슬립(SLIP)되면서 발생되는 징크트리(ZINC TREE:아연가루)(10)가 쌓이게 되며, 이렇게 축적된 징크트리(10)는 경우에 따라 상기 스트립(도금된 강판)(2)의 표면에 심한 밴드마크(5)를 형성하게 된다.As shown in FIG. 2, this is done by excluding the band 7 and the band 7 of the central portion of the conductor roll 1 wound around its outer circumference so as to supply a negative current to the conductor roll 1. ZINC TREE (zinc powder) 10 generated by slippering the conductor roll 1 and the strip 2 between the spaces formed with the step T with the rubber 8 on both ends of the roll 1 The stacked zinc tree 10 may form a severe band mark 5 on the surface of the strip (plated steel plate) 2 in some cases.

미설명 부호 '6'은 철피이고, '9'는 스폰지를 도시한 것으로, 상기스폰지(9)는 밴드(7)와 러버(8)가 단절되어 있으므로 그 사이로 유입되는 먼지, 수분 등을 제거 혹은 침투방지를 위해 착탈가능하게 설치된다.Reference numeral '6' is a bar, '9' shows a sponge, the sponge (9) because the band (7) and the rubber (8) is disconnected to remove dust, moisture, etc. introduced between them or It is detachably installed to prevent penetration.

본 발명은 상술한 바와 같은 종래 기술이 갖는 제반 문제점을 감안하여 이를 해소코자 창안한 것으로, 스트립이 아연도금조를 지난 후 컨덕터롤 표면과 접촉할 때에만 컨덕터롤 밴드와 러버 사이의 단차를 줄이도록 함으로써 징크트리의 축적을 원천적으로 차단하여 밴드마크의 발생을 억제할 수 있도록 한 컨덕터롤 밴드마크 방지장치를 제공함에 그 목적이 있다.The present invention has been made in view of the above-described problems of the prior art, so as to reduce the step between the conductor roll band and the rubber only when the strip contacts the conductor roll surface after the galvanizing bath. Therefore, the object of the present invention is to provide a conductor roll band mark prevention device that can block the accumulation of the zinc source and thereby suppress the generation of the band mark.

이하에서는, 본 발명에 따른 바람직한 일 실시예를 첨부도면에 의거하여 보다 상세하게 설명한다.Hereinafter, a preferred embodiment according to the present invention will be described in more detail on the basis of the accompanying drawings.

도 3은 본 발명에 따른 밴드마크 방지장치가 설치된 컨덕터롤을 일부 절개하여 도시한 횡단면도이고, 도 4는 도 3의 A-A선 단면도이다.3 is a cross-sectional view showing a part of the conductor roll provided with a band mark prevention device according to the present invention, Figure 4 is a cross-sectional view taken along line A-A of FIG.

도 3 내지 도 4에 도시된 바와 같이, 컨덕터롤(1)의 밴드(7)와 러버(8)가 만나는 경계부에 인접하여 러버(8)측으로 일정한 공간인 후술할 설치홈(50)을 형성하고 상기 설치홈(50) 내에 지렛대의 원리를 이용한 작동판(20)을 설치한다.As shown in FIGS. 3 to 4, adjacent to the boundary portion where the band 7 and the rubber 8 of the conductor roll 1 meet, the installation groove 50 to be described later, which is a predetermined space, is formed on the rubber 8 side. The operation plate 20 using the principle of the lever in the installation groove 50 is installed.

작동판(20)은 대략 수평한 두개의 판이 경사지게 연결된 'Z'의 역형상을 갖는다.The operating plate 20 has an inverted shape of 'Z' in which two substantially horizontal plates are connected obliquely.

작동판(20)의 하측지지부(22)와 상측지지부(24)가 연결되는 지점의 일부에는 고정핀(28)이 회전가능하게 삽입되고, 상기 고정핀(28)은 지지브라켓(30)에 고정된다.The fixing pin 28 is rotatably inserted at a part of the lower support portion 22 and the upper support portion 24 of the operation plate 20, and the fixing pin 28 is fixed to the support bracket 30. do.

상기 지지브라켓(30)은 철피(6)를 따라 일정간격으로 다수개 돌출형성된다.The support bracket 30 is formed with a plurality of protrusions at regular intervals along the steel shell (6).

그리고, 스프링(26)이 개재되는 바, 상기 스프링(26)의 일단은 상측지지부(24)의 하단면 중앙에 고정되고 타단은 철피(6)에 고정된다.And, the spring 26 is interposed, one end of the spring 26 is fixed to the center of the lower end surface of the upper support portion 24 and the other end is fixed to the steel shell (6).

따라서, 상기 작동판(20)은 도 4의 도시와 같이 컨덕터롤(1)의 외주연에 씌워진 철피(6)를 따라 다수개 설치되는 바, 상기 작동판(20)은 상기 컨덕터롤(1)을 구성하는 밴드(7)와 러버(8) 사이의 위치의 설치홈(50)내에만 설치된다.Therefore, the operating plate 20 is installed in a plurality along the bar shell 6 covered on the outer periphery of the conductor roll (1) as shown in Figure 4, the operating plate 20 is the conductor roll (1) It is installed only in the installation groove 50 of the position between the band 7 and the rubber 8 constituting the.

도 5는 본 발명에 따른 밴드마크 방지장치의 작동관계를 도시한 작동상태도이다.5 is an operating state diagram showing an operation relationship of the band mark prevention apparatus according to the present invention.

도 5에 따르면, 설치홈(50)은 전술한 작동판(20)의 형상과 대응되게 러버(8)의 일부가 절개형성되는 바, 밴드(7)의 경계면 하측부인 철피(6)와 접하는 부위가 일정크기로 절개되어 형성된다.According to Figure 5, the installation groove 50 is a portion of the rubber (8) is cut to correspond to the shape of the operating plate 20 described above, the portion in contact with the steel shell 6, which is the lower side of the boundary surface of the band (7) Is cut to a certain size and formed.

즉, 상기 설치홈(50)은 원형띠 형상을 이룬다.That is, the installation groove 50 forms a circular band shape.

상기 설치홈(50)에는 지지브라켓(30)과 고정핀(28)에 의해 회전가능하게 고정된 작동판(20)이 구비되고, 상기 작동판(20)의 일측인 스폰지(9)에 인접한 쪽에는 수지물이 발포충전되어 발포수지층(52)을 이룬다.The installation groove 50 is provided with a working plate 20 rotatably fixed by a support bracket 30 and a fixing pin 28, the side adjacent to the sponge 9, which is one side of the operating plate 20 The resin is foamed and filled to form a foamed resin layer (52).

상기 발포수지층(52)은 작동판(20)의 하측지지부(22) 배면에 발포충전되도록 하여 상기 하측지지부(22)가 하강하여 철피(6)와 접촉되지 못하도록 하여줌이 바람직하다.The foamed resin layer 52 is preferably foamed and filled on the back of the lower support portion 22 of the operating plate 20 to prevent the lower support portion 22 from falling to contact the steel shell 6.

특히, 상기 작동판(20)의 상측지지부(22) 상면이 면접촉되는 설치홈(50)의 내측 상면은 다른쪽보다 얇게 형성된다. 즉, 상측지지부(22)가 위치된 부위의 러버(8) 두께는 상대적으로 매우 얇게 형성된다.In particular, the inner upper surface of the installation groove 50 in which the upper surface of the upper support portion 22 of the operation plate 20 is in surface contact is formed thinner than the other. That is, the thickness of the rubber 8 at the portion where the upper support 22 is located is relatively thin.

이와 같이 구성된 본 발명은 도 4에 도시된 A의 경우와 같이 스트립(2)이 없을 때에는 스프링(26)의 인장력에 의해 작동판(20)의 상측지지부(24)는 고정핀(28)을 중심으로 최대한 상향이동되려고 하고 이에 따라 그 대향단인 하측지지부(22)는 최대한 발포수지층(52)에 밀착되어 위치되게 된다.In the present invention configured as described above, when the strip 2 is absent as in the case of A shown in FIG. 4, the upper support part 24 of the operating plate 20 is centered on the fixing pin 28 by the tension force of the spring 26. The lower support portion 22, which is the opposite end, is positioned to be in close contact with the foamed resin layer 52 as much as possible.

따라서, 컨덕터롤(1)의 밴드(7)와 러버(8) 사이에는 그대로 단차를 유지하게 된다.Therefore, the step is maintained as it is between the band 7 and the rubber 8 of the conductor roll 1.

이러한 상태에서 B의 경우와 같이 스트립(2)이 이동되어 위치되게 되면 이동하는 스트립(2)의 하중이 충분히 두께가 얇은 러버(8)의 설치홈(50) 상면에 작용하게 된다.In this state, when the strip 2 is moved and positioned as in the case of B, the load of the moving strip 2 acts on the upper surface of the installation groove 50 of the rubber 8 having a sufficiently thin thickness.

동시에, 작동판(20)의 상측지지부(24)가 하중을 받아 스프링(26)의 인장력을극복하고 하강하게 되고, 상기 상측지지부(24)의 하강에 따라 고정핀(28)을 중심으로 하측지지부(22)가 상승되면서 상기 하측지지부(22)의 상면에 거치된 러버(8)를 밀어 올리게 된다.At the same time, the upper support portion 24 of the operating plate 20 receives a load, overcomes the tensile force of the spring 26, and descends, and the lower support portion centers around the fixing pin 28 as the upper support portion 24 descends. As the 22 is raised, the rubber 8 mounted on the upper surface of the lower support part 22 is pushed up.

따라서, 러버(8)는 밴드(7)와의 단차를 최대한 줄이면서 거의 수평상태로 놓이게 되고 이에 따라 러버(8)와 밴드(7) 사이의 단차가 없어짐으로써 스트립(2)의 슬립에 의해 발생된 징크트리(아연가루)는 적층되지 못하고 외부로 배출되어 버리게 된다.Thus, the rubber 8 is placed in a substantially horizontal state while minimizing the step with the band 7 and thus eliminates the step between the rubber 8 and the band 7, which is caused by the slip of the strip 2. Zinc tree (zinc powder) is not laminated and is discharged to the outside.

이와 같이 징크트리의 적층현상이 생기지 않으므로 밴드마크의 발생이 현저히 줄어들게 된다.As such, the lamination phenomenon of the zinc tree does not occur, and the occurrence of the band mark is significantly reduced.

이상에서 상세히 설명한 바와 같이, 본 발명은 스트립이 컨덕트롤을 통과할 때에는 밴드와 러버 사이의 단차가 없어지고 스트립이 통과되지 않을 경우에는 단차를 유지하므로 밴드마크의 발생을 현격히 줄어 고품질의 도금강판을 생산할 수 있게 된다.As described above in detail, the present invention eliminates the step between the band and the rubber when the strip passes through the control, and maintains the step when the strip does not pass, thereby significantly reducing the occurrence of the band mark, and thus providing a high quality plated steel sheet. Will be able to produce.
