Description

롤 직경 측정장치{a measuring device of roll diameter}Roll measuring device {a measuring device of roll diameter}

발명은 냉연 설비의 각 라인에 설치되어 있는 롤(Roll)의 직경을 측정하는 장치에 관한 것이다.The invention relates to an apparatus for measuring the diameter of rolls provided in each line of a cold rolling facility.

냉연설비의 각 라인에는 냉연제품을 생산하기 위하여, 수 많은 종류의 롤들이 설치되어 스트립을 이송하고 있는데, 특히 이 롤들 가운데 텐션 브라이들롤(Tension Bridle Roll)은 PLG가 부착되어 회전수를 측정,그 결과를 피이드 백(Feed Back)하면서, 스트립의 원할한 흐름과 라인운전에 필요한 장력을 부여하는 역할을 하는 롤로서, 롤 자체의 직경관리가 매우 중요하여, 마모나 교환 등으로롤 직경의 변화가 발생하면 제어 프로그램에서 해당 롤의 직경을 수정,입력하여 정상적으로 장력이 작용될 수 있도록 재 설정을 하고 있다.In order to produce cold rolled products, a large number of rolls are installed in each line of the cold rolling equipment to transfer strips. In particular, the tension bridle roll has a PLG attached to measure the rotational speed. It is a roll that feeds the result and provides a smooth flow of the strip and a tension required for line operation. The diameter of the roll itself is very important, and the roll diameter is changed due to wear or exchange. When the error occurs, the control program resets the diameter so that tension can be applied normally by correcting and inputting the diameter of the roll.

그리고 이외 롤들의 직경은 스트립의 슬립(Slip) 발생방지와 편마모에 의한 스트립 사행방지 및 품질 확보를 위하여, 주기적으로 롤경을 측정하여, 정비자료로 사용하고 있는데, 종래에는 측정대상 롤 측정은 스트립이 각 롤에 접촉되어 있기 때문에 테프(Tape)식 측정자(테이프형상의 것을 감아서 롤경을 측정하는 것)를 이용할 수가 없어서,각 롤간에 걸려 있는 스트립의 중간을 절단하고, 측정대상 롤부분에 걸쳐 있는 절단된 스트립을 제거한 후 롤경을 측정하고, 측정 후에는 절단된 스트립을 용접하여 연속라인의 운전이 가능토록 하고 있다.In addition, the diameter of the rolls is used as maintenance data by measuring the roll diameter periodically to prevent slip occurrence of the strip and to prevent strip meandering by uneven wear and to ensure quality. Since it is in contact with each roll, it is not possible to use a tape measurer (when measuring a roll diameter by winding a tape-shaped thing), so that the middle of the strip hung between the rolls is cut off, After removing the cut strip, the roll diameter is measured, and after the measurement, the cut strip is welded to allow continuous line operation.

그런데 이런 과정에서 발생하는 스트립의 손실과 용접부가 라인 출측으로 빠져 나갈 때까지 도중에 설치된 고무 롤의 표면을 손상시키는 현상이 발생하기도 하며, 측정대상 롤의 원통을 한바퀴 감아서 양끝을 당겨서 직경을 측정하는 테프(Tape)식 측정자는 사람에 따라, 측정오차가 크게 발생하여 자료의 신뢰도를 저하시키고 있는 실정이다.However, the loss of the strip and the damage of the surface of the rubber roll installed on the way until the weld part exits to the line exit side may occur. Tape measurer is a situation that the measurement error occurs a lot, depending on the person is reducing the reliability of the data.

따라서 본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로 스트립 중간을 절단하여 스트립 을 제거하지 않고도 원 거리에서 측정이 필요한 롤의 직경을 정확하게 측정하는 하기 위한 장치를 제공하는 것을 그 목적으로 한다.Accordingly, an object of the present invention is to provide an apparatus for accurately measuring the diameter of a roll that needs to be measured at a distance without removing the strip by cutting the middle of the strip to solve the above problems.

상기 슬라이드가이드(5)의 일측부에 설치 고정되는 투수광기(7);와 측정대상 롤(1)의 측면부에 부착되어 투수광기(7)가 보내는 광을 반사하는 반사부(9);와 측정대상 롤(1)의 표면과 접촉하여 롤(1)의 회전과 함께 회전하여 롤(1)의 회전둘레를 측정하는 측정휠(2); 및 투수광기(7)에 의해 감지되는 롤(1)의 1회전 신호에 따라 측정휠(2)의 회전수를 이용하여 롤(1)의 직경을 표시하는 제어부(10)를 포함하여서 된 구성인 것을 특징으로 하는 롤 직경 측정 장치를 제공하는 것에 의해 달성된다.A light receiver 7 installed at one side of the slide guide 5 and fixed to it; and a reflector 9 attached to the side of the measurement target roll 1 to reflect light transmitted from the light receiver 7; and measurement A measuring wheel 2 in contact with the surface of the object roll 1 to rotate together with the rotation of the roll 1 to measure the rotational circumference of the roll 1; And a control unit 10 for displaying the diameter of the roll 1 using the rotation speed of the measuring wheel 2 according to the one rotation signal of the roll 1 sensed by the light projector 7. It is achieved by providing a roll diameter measuring device characterized in that.

도면에서 미설명부호 8은 투수광기(7) 고정용 세트볼트이고, 도면부호 14는 지지스탠드의 높이 조정용 노브(knob)이며, 도면부호 12는 제어부(10)와 투수광기(7)를 연결하는 케이블이고, 도면부호 13은 측정휠(2)의 회전수를 측정하기 위한 플레시블 샤프트(flexible shaft, 가요성축)이다. 또한, 도면부호 15는 슬라이드바(11)의 수평을 유지하기 위한 수준기이며, 도면부호 16은 스크류너트(6)를 회전시키기 위한 핸들이다.In the drawing, reference numeral 8 is a set bolt for fixing the light receiver 7, reference numeral 14 is a knob for adjusting the height of the support stand, and reference numeral 12 is a part connecting the control unit 10 and the light receiver 7 to each other. It is a cable, and 13 is a flexible shaft for measuring the rotation speed of the measuring wheel 2. In addition, reference numeral 15 is a level for maintaining the horizontal of the slide bar 11, and reference numeral 16 is a handle for rotating the screw nut (6).

도 2 및 도 3에는 본 발명의 측정부의 상세도인데 동 도면에서, 미설명된 도면부호 11a는 덮개로서 개재너트(30, 부쉬)를 사이에 두고 볼트 및 너트에 의해 체결된다.2 and 3 are detailed views of the measuring unit of the present invention, in which the reference numeral 11a, which is not described, is fastened by bolts and nuts with an interposition nut 30 (bush) interposed therebetween as a cover.

한편, 도면부호 2a는 보조휠로서 롤직경의 측정은 롤표면에 접촉되어 있는 측정휠(2)에 의해 이루어지고 상기 보조휠(2a)은 단순히 측정부를 가이드하기 위한 역할만을 한다. 즉 상기 보조휠(2a)을 사용함으로써 롤표면과 휠이 2점에서 접촉하면서 회전하게 되어 측정휠(2)의 회전이 진동 없이 더욱 안정적으로 이루어지는 것이다. 따라서, 보조휠은 필수적인 것은 아니다.On the other hand, reference numeral 2a is an auxiliary wheel and the measurement of the roll diameter is made by the measuring wheel 2 in contact with the roll surface, and the auxiliary wheel 2a merely serves to guide the measuring unit. That is, by using the auxiliary wheel (2a) is rotated while contacting the roll surface and the wheel at two points, the rotation of the measuring wheel (2) is made more stable without vibration. Therefore, the auxiliary wheel is not essential.

상기의 구성인 본 발명에 따른 장치의 작동과정은 다음과 같다.The operation process of the apparatus according to the present invention having the above configuration is as follows.

측정대상 롤(1)의 임의의 위치에 마그네틱 베이스(4b)를 위치시킨 후, 제어부(10)와 측정휠(2)사이에 플렉시블 사프트(13)를, 투수광기에는 케이블(12)를 제어부(10)에 연결하고 측정위치 선정용 핸들(16)을 돌려서 측정하고자 하는 측정롤(1)의 측정위치에 측정 휠(Wheel)(2)이 위치하도록 한 뒤, 양측 슬라이드가이드(5)을 상하로 움직이면서, 수준기(15)의 물방울이 정중앙에 오도록 하여 높이 조정용 노브(Knob)(11)를 고정시킨다.After positioning the magnetic base 4b at an arbitrary position of the measurement target roll 1, the flexible shaft 13 is connected between the control unit 10 and the measuring wheel 2, and the cable 12 is connected to the light receiver. 10) and the measuring wheel (2) is positioned at the measuring position of the measuring roll (1) to be measured by turning the handle (16) for selecting the measuring position, and then the two slide guides (5) up and down While moving, the height adjustment knob Knob 11 is fixed so that the water droplet of the level 15 is in the center.

이때 측정 휠(Wheel)(2)이 피측정롤(1) 표면에 일정하게 접촉할 수 있게 마그네틱 베이스(4b)의 위치를 적절히 수정한다.At this time, the position of the magnetic base 4b is appropriately modified so that the measuring wheel 2 can be in constant contact with the surface to be measured 1.

반사부(9)를 피측정롤(1)측면의 적당한 위치에 부착하고, 투수광기(7)와의 영점조정을 위하여 투수광기(7) 조정용 세트볼트(8)를 풀면, 투수광기(7)는 피측정롤(1)의 축방향에 평행으로 이동하면서 슬라아드바(11)의 중심에 대하여 회전하는 구조이기 때문에, 반사부(9)에 대하여 투수광기(7)의 영점조정이 가능하고, 영점조정 완료되면 제어부(10)의 영점조정 램프가 점등된다. 이것을 확인하고 , 세트볼트(8)를 고정하면 롤직경 측정준비가 완료 된다.The reflector 9 is attached to an appropriate position on the side of the roll 1 to be measured, and when the light receiver 7 adjustment set bolt 8 is loosened for zero adjustment with the light receiver 7, the light receiver 7 is Since the structure rotates about the center of the slide bar 11 while moving in parallel with the axial direction of the roll 1 to be measured, zero adjustment of the light receiving receiver 7 with respect to the reflecting portion 9 is possible. When the adjustment is completed, the zero adjustment lamp of the controller 10 is turned on. After confirming this, the set bolt 8 is fixed and the roll diameter measurement preparation is completed.

스트립(미도시)이 걸린 상태이므로, 피측정롤(1) 전후에 걸려있는 스트립의 상태를 확인하면서, 조그(Jog)운전을 실시하여, 스트립을 이송시키면, 피측정롤(1)이 회전하므로 롤에 부착된 반사부(9)와 투수광기(7)가 영점을 상실하여, 투수광기(7)가 보내 오던 신호는 차단되어, 제어부(10)에서는 측정 중임을 인식하고, 측정 휠(Wheel)(3)의 회전량은 플렉시블 사프트(13)을 통하여 제어부(10)에 내장된 엔코더에 전달된다.Since the strip (not shown) is jammed, the jog operation is carried out while checking the state of the strip hanging before and after the roll 1 to be measured. The reflector 9 and the light receiver 7 attached to the roll lose the zero point, and the signal transmitted by the light receiver 7 is blocked, and the control unit 10 recognizes that the measurement is in progress, and measures the measurement wheel. The amount of rotation of (3) is transmitted to the encoder built in the control unit 10 via the flexible shaft 13.

측정대상 롤(1)이 1회전을 완료하여, 반사부(9)가 원래의 위치로 되 돌아와, 투수광기(7)와 일치하면 제어부(10)에서는, 측정대상 롤(1)이 1회전 한 것으로 판단하여, 그때까지의 측정 흴(Wheel)(2)의 회전량을 측정대상 롤(1)의 직경으로 연산하여, 제어부(10)의 창에 디스플레이 한다.When the measurement target roll 1 completes one rotation and the reflecting portion 9 returns to its original position and coincides with the light receiver 7, the control unit 10 rotates the measurement target roll 1 once. It is judged that the rotation amount of the measurement wheel 2 until then is computed by the diameter of the measurement object roll 1, and it displays on the window of the control part 10. FIG.

한편, 측정대상 롤(1)의 길이 방향의 다른 부분을 측정할 필요가 있을 때에는, 어느 한 쪽의 마그네틱 베이스(4b)를 측정 휠(Wheel)(3)이 측정대상 롤(1)과 접촉되지 않을 정도로 약간 이동시킨 뒤, 측정위치 선정용 핸들(16)을 좌우로 돌리면 슬라이드바(11)의 일단과 체결된 스크류너트(6)가 회전하게 되어, 양측의 슬라이드가이드 (5)에 안내 되며, 따라서 상기 슬라이드바(11)에 고정된 측정휠(2)이 이동되므로 필요한 측정위치를 선정하여 측정을 계속 할 수 있게 된다.On the other hand, when it is necessary to measure another part in the longitudinal direction of the measuring object roll 1, the measuring wheel (Wheel) 3 does not contact the measuring object roll 1 with either of the magnetic bases 4b. After moving slightly so as not to rotate, the screw nut 6 engaged with one end of the slide bar 11 is rotated by turning the handle 16 for measurement position selection to the left and right, and guided to the slide guides 5 on both sides. Therefore, since the measuring wheel 2 fixed to the slide bar 11 is moved, it is possible to continue the measurement by selecting the required measuring position.

이상과 같이 본 발명에 의하면, 롤 직경을 측정하기 위해 스트립의 중간을 절단, 제거하지 않아도 되며, 스트립 이 걸쳐진 상태에서 롤 직경을 측정할 수 있어 종래 스트립 절단부를 용접하여 작업 준비를 하는 불필요한 공수를 제거하여 스트립 손상과 용접부 통과시 발생하는 고무 롤 표면의 손상을 방지하였으며 인력으로 측정자를 당겨서 측정할 때 발생하는 측정오차를 제거 할 수 있게되었다.As described above, according to the present invention, it is not necessary to cut and remove the middle of the strip to measure the roll diameter, and the roll diameter can be measured in the state where the strip is stretched, thereby eliminating unnecessary airborne welding and preparing the work by welding the conventional strip cut. This prevents damage to the strip and damage to the rubber roll surface when passing through the welds.
