The contact surface portion 125 corresponds one-to-one to the inclined surface portion 122 of the mandrel body 121. The segment member 124 corresponds one-to-one to a row of the inclined surface portions 122 formed along the longitudinal direction of the mandrel body 121. When the inclined surface portion 122 is arranged in four rows parallel to the longitudinal direction of the mandrel body 121, four segment members 124 are provided.
링크부재(127)는 세그먼트부재(124)와 맨드릴 바디(121)를 링크 결합한다. 링크부재(127)는 세그먼트부재(124)가 맨드릴 바디(121)의 길이방향을 따라 일정 거리 범위에서 이동되도록 한다. 맨드릴 바디(121)가 세그먼트부재(124)에 대하여 상대적으로 이동되는 경우, 맨드릴 바디(121)의 경사면부(122)가 세그먼트부재(124)의 접촉면부(125)와 슬라이딩하면서 이동된다. 이때, 세그먼트부재(124)가 맨드릴 바디(121)의 중심부에서 멀어지거나 가까워지므로, 세그먼트부재(124)의 외경이 확대되거나 축소된다.The link member 127 links the segment member 124 and the mandrel body 121. The link member 127 allows the segment member 124 to be moved in a predetermined distance along the longitudinal direction of the mandrel body 121. When the mandrel body 121 is moved relative to the segment member 124, the inclined surface portion 122 of the mandrel body 121 is moved while sliding with the contact surface portion 125 of the segment member 124. At this time, since the segment member 124 moves away from or close to the center of the mandrel body 121, the outer diameter of the segment member 124 is enlarged or reduced.
이동 장치(128)는 맨드릴 바디(121)에 연결된다. 이동 장치(128)의 작동에 따라 맨드릴 바디(121)는 세그먼트부재(124)에 대하여 상대적으로 이동된다. 이로써 이동 장치(128)의 작동 시 세그먼트부재(124)의 외경이 확대 및 축소될 수 있다.The moving device 128 is connected to the mandrel body 121. As the movement device 128 operates, the mandrel body 121 is moved relative to the segment member 124. As a result, the outer diameter of the segment member 124 may be enlarged and reduced when the moving device 128 operates.
이동 장치(128)는 맨드릴 바디(121)에 연결되는 로드(128a)와, 로드(128a)가 삽입되는 실린더(128b)를 포함한다. 실린더(128b)에 유체가 공급됨에 따라 로드(128a)가 실린더(128b)에서 인출되고, 실린더(128b)에서 유체가 배출됨에 따라 로드(128a)가 실린더(128b)의 내부로 인입된다. 로드(128a)가 이동됨에 따라 맨드릴 바디(121)가 좌우방향으로(도 2 기준) 이동된다.The moving device 128 includes a rod 128a connected to the mandrel body 121 and a cylinder 128b into which the rod 128a is inserted. As the fluid is supplied to the cylinder 128b, the rod 128a is drawn out of the cylinder 128b, and as the fluid is discharged from the cylinder 128b, the rod 128a is drawn into the cylinder 128b. As the rod 128a is moved, the mandrel body 121 is moved in the left and right directions (see FIG. 2).
가압부(150)는 맨드릴(120)의 둘레부에 복수 개가 배치된다. 가압부(150)는 맨드릴(120)에 감기는 압연 코일(C)을 가압한다. 가압부(150)는 가압 피스톤(151), 가압 프레임(153) 및 가압 롤러(155)를 포함한다. The plurality of pressing units 150 are disposed at the circumference of the mandrel 120. The pressing unit 150 presses the rolling coil C wound around the mandrel 120. The pressurizing part 150 includes a pressurizing piston 151, a pressurizing frame 153, and a pressurizing roller 155.
가압 피스톤(151)은 맨드릴(120)의 둘레에서 힌지부(151c)에 의해 권취 바디(110)에 회전 가능하게 설치된다. 가압 피스톤(151)은 가압 실린더(151a)와 가압 로드(151b)를 포함한다. 가압 실린더(151a)에 유체가 공급됨에 따라 가압 로드(151b)가 가압 실린더(151a)에서 인출되고, 가압 실린더(151a)에서 유체가 배출됨에 따라 가압 로드(151b)가 가압 실린더(151a)의 내부로 인입된다. The pressure piston 151 is rotatably installed on the winding body 110 by the hinge portion 151c around the mandrel 120. The pressure piston 151 includes a pressure cylinder 151a and a pressure rod 151b. As the fluid is supplied to the pressure cylinder 151a, the pressure rod 151b is drawn out of the pressure cylinder 151a, and as the fluid is discharged from the pressure cylinder 151a, the pressure rod 151b is inside the pressure cylinder 151a. Is pulled in.
가압 프레임(153)은 가압 피스톤(151)의 가압 로드(151b)에 결합된다. 가압 프레임(153)에는 거리 측정 장치(130)가 배치된다. 가압 로드(151b)가 가압 실린더(151a)에서 인입 또는 인출됨에 따라 가압 프레임(153)과 맨드릴(120)의 세그먼트부재(124) 사이의 간격이 조절된다.The pressure frame 153 is coupled to the pressure rod 151b of the pressure piston 151. The distance measuring device 130 is disposed on the pressing frame 153. As the pressure rod 151b is drawn in or withdrawn from the pressure cylinder 151a, a gap between the pressure frame 153 and the segment member 124 of the mandrel 120 is adjusted.
가압 롤러(155)는 가압 프레임(153)의 일면, 구체적으로 맨드릴(120)에 대향되는 면에 배치된다. 가압 롤러(155)는 맨드릴(120)에 감기는 압연 코일(C)을 가압하여 압연 코일(C)이 맨드릴(120)에 밀착된 상태로 감기도록 한다. 예를 들면, 압연 코일(C)이 맨드릴(120)에 감길 때에 가압 실린더(151a)에 유체가 공급됨에 따라 가압 로드(151b)가 가압 실린더(151a)에서 인출된다. 가압 롤러(155)가 압연 코일(C)에 접촉될 때가지 가압 로드(151b)가 가압 실린더(151a)에서 인출된다. 따라서 압연 코일(C)이 맨드릴(120)에 감길 때에 가압 롤러(155)가 압연 코일(C)과 구름 접촉되면서 회전된다.The pressure roller 155 is disposed on one surface of the pressure frame 153, specifically, a surface opposite to the mandrel 120. The pressure roller 155 presses the rolling coil C wound around the mandrel 120 so that the rolling coil C is wound in close contact with the mandrel 120. For example, when the rolling coil C is wound around the mandrel 120, the fluid is supplied to the pressure cylinder 151a so that the pressure rod 151b is drawn out of the pressure cylinder 151a. The pressure rod 151b is withdrawn from the pressure cylinder 151a until the pressure roller 155 contacts the rolling coil C. As shown in FIG. Therefore, when the rolling coil C is wound around the mandrel 120, the pressure roller 155 is rotated while rolling contact with the rolling coil C.
거리 측정 장치(130)는 가압부(150)에 설치된다. 이때 거리 측정 장치(130)는 가압부(150)마다 설치되거나 또는 하나의 가압부(150)에만 설치될 수 있다. 거리 측정 장치(130)는 측정대상물로부터 거리 측정 장치(130)까지의 거리를 측정한다. 측정대상물로는 맨드릴(120)이나 맨드릴(120)에 권취되는 압연 코일(C)일 수 있다. 따라서 측정대상물이 맨드릴(120)인 경우 거리 측정 장치(130)는 맨드릴(120)로부터 거리 측정 장치(130)까지의 거리를 측정하고, 측정대상물이 맨드릴(120)에 권취되는 압연 코일(C)인 경우 거리 측정 장치(130)는 압연 코일(C)로ㅜ터 거리 측정 장치(130)까지의 거리를 측정한다. The distance measuring device 130 is installed in the pressing unit 150. In this case, the distance measuring device 130 may be installed for each pressing unit 150 or may be installed only in one pressing unit 150. The distance measuring device 130 measures the distance from the measurement object to the distance measuring device 130. The measurement object may be a rolling coil C wound around the mandrel 120 or the mandrel 120. Therefore, when the measurement object is the mandrel 120, the distance measuring device 130 measures the distance from the mandrel 120 to the distance measuring device 130, and the rolling coil C in which the measurement object is wound on the mandrel 120. In the case of the distance measuring device 130 measures the distance to the coil distance measuring device 130 by the rolling coil (C).
거리 측정 장치(130)는 냉각 매체에 의해 냉각된다. 따라서 거리 측정 장치(130)가 맨드릴(120) 또는 압연 코일(C)과 근접 거리에 설치되더라도 맨드릴(120) 또는 압연 코일(C)에서 발생되는 열기에 의해 손상되는 것을 방지할 수 있다. The distance measuring device 130 is cooled by the cooling medium. Therefore, even if the distance measuring device 130 is installed at a close distance from the mandrel 120 or the rolling coil (C) it can be prevented from being damaged by the heat generated from the mandrel 120 or the rolling coil (C).
제어부(160)는 거리 측정 장치(130)에서 측정된 거리에 의해 가압부(150)와 맨드릴(120) 또는 가압부(150)와 맨드릴(120)에 권취된 압연 코일(C)과의 간격을 조절한다. 거리 측정 장치(130)를 통해 맨드릴(120)과 가압부(150) 사이의 거리, 또는 맨드릴(120)에 권취된 압연 코일(C)과 가압부(150) 사이의 거리를 실시간으로 측정할 수 있고, 측정된 값을 토대로 제어부(160)를 통해 가압부(150)와 맨드릴(120)간의 간격, 또는 가압부(150)와 맨드릴(120)에 권취된 압연 코일(C)간의 간격을 조정할 수 있다. The controller 160 measures the distance between the pressing unit 150 and the mandrel 120 or the rolling coil C wound around the pressing unit 150 and the mandrel 120 by the distance measured by the distance measuring device 130. Adjust The distance between the mandrel 120 and the pressing unit 150 or the distance between the rolling coil C and the pressing unit 150 wound around the mandrel 120 may be measured in real time through the distance measuring device 130. The distance between the pressing unit 150 and the mandrel 120 or the interval between the pressing unit 150 and the rolling coil C wound around the mandrel 120 may be adjusted based on the measured value. have.
이와 같이 가압부(150)와 측정대상물인 맨드릴(120) 또는 맨드릴(120)에 권취된 압연 코일(C)간의 간격이 실시간으로 조정되므로, 압연 코일(C)이 맨드릴(120)에 감기기 이전에는 가압부(150)의 가압롤러(155)가 맨드릴(120)과 접촉되어 가압롤러(155)가 손상되는 것을 방지할 수 있고, 압연 코일(C)이 맨드릴(120)에 권취된 이후에는 가압부(150)의 가압롤러(155)가 압연 코일(C)을 과다하게 가압함으로써 가압롤러(155) 또는 압연 코일(C)이 손상되는 것을 차단할 수 있다. As such, the interval between the pressing unit 150 and the rolling coil C wound around the mandrel 120 or the mandrel 120, which is the measurement object, is adjusted in real time, before the rolling coil C is wound on the mandrel 120. The pressing roller 155 of the pressing unit 150 may be in contact with the mandrel 120 to prevent the pressing roller 155 from being damaged. After the rolling coil C is wound around the mandrel 120, the pressing unit may be pressed. The pressing roller 155 of 150 may block the pressing roller 155 or the rolling coil C from being damaged by excessively pressing the rolling coil C.
제어부(160)는 맨드릴(120)에 권취된 압연 코일(C)의 두께에 따라 맨드릴(120)과 가압부(150) 사이의 간격을 적절하게 조절할 수 있다. 즉, 제어부(160)는 거리 측정 장치(130)에서 측정된 압연 코일(C)의 표면으로부터의 거리를 판단하고, 가압 피스톤(151)을 제어하여 맨드릴(120)과 가압부(150) 사이의 간격을 조절한다. 이로써 맨드릴(120)에 권취된 압연 코일(C)의 두께가 두꺼워지는 만큼 가압부(150)의 가압롤러(155)를 맨드릴(120)로부터 이격시킬 수 있으므로, 압연 코일(C)의 두께가 변경되더라도 일정한 가압력으로 가압롤러(155)가 압연 코일(C)을 가압하게 할 수 있다. 바꿔 말해, 거리 측정 장치(130)를 통해 맨드릴(120)에 권취된 압연 코일(C)까지의 거리를 실시간으로 측정할 수 있으므로, 압연 코일(C)의 두께 변화에 즉각적으로 대응하여 가압롤러(155)의 위치를 조정할 수 있게 되는 것이다. The controller 160 may appropriately adjust the distance between the mandrel 120 and the pressing unit 150 according to the thickness of the rolling coil C wound on the mandrel 120. That is, the controller 160 determines the distance from the surface of the rolling coil C measured by the distance measuring device 130, and controls the pressure piston 151 to control the pressure between the mandrel 120 and the pressure unit 150. Adjust the interval. As a result, since the thickness of the rolling coil C wound around the mandrel 120 becomes thicker, the pressing roller 155 of the pressing unit 150 can be separated from the mandrel 120, so that the thickness of the rolling coil C is changed. Even if it is, the pressure roller 155 can be made to press the rolling coil (C) by a constant pressing force. In other words, since the distance to the rolling coil C wound around the mandrel 120 can be measured in real time through the distance measuring device 130, the pressure roller (1) responds immediately to the change in the thickness of the rolling coil (C). 155) can be adjusted.
맨드릴(120)의 하측에는 레일(117)이 배치된다. 레일(117)에는 권취된 압연 코일(C)을 탑재하여 이송할 수 있도록 코일 이송 장치(170)가 설치된다. The rail 117 is disposed below the mandrel 120. The rail 117 is provided with a coil transfer device 170 to mount and transport the wound rolled coil C.
코일 이송 장치(170)는 프레임(171)과, 프레임(171)의 양측에 배치되고, 레일(117)을 따라 회전되는 구동휠(172)과, 프레임(171)에 승강 가능하게 설치되는 승강부(174)와, 승강부(174)를 승강시키는 승강 피스톤(176)과, 승강부(174)의 상측에 배치되어 권취된 압연 코일(C)을 지지하는 롤러(177)를 포함한다. The coil conveying apparatus 170 is disposed on both sides of the frame 171, the frame 171, a driving wheel 172 rotated along the rail 117, and a lifting unit mounted on the frame 171 so as to be elevated. 174, an elevating piston 176 for elevating and elevating the elevating portion 174, and a roller 177 for supporting the rolled coil C, which is disposed above the elevating portion 174 and is wound.
롤러(177)에 권취된 압연 코일(C)이 탑재되면, 승강부(174)가 승강 피스톤(176)에 의해 하강된다. 이어 구동휠(172)이 구동됨에 따라 압연 코일 이송 장치(170)가 압연 코일용 권취 장치의 외부로 이송되면서 압연 코일(C)이 외부로 옮겨진다. When the rolling coil C wound around the roller 177 is mounted, the lifting unit 174 is lowered by the lifting piston 176. Then, as the driving wheel 172 is driven, the rolling coil C is transferred to the outside of the winding coil winding device 170 while the rolling coil C is moved to the outside.

It is a perspective view which shows the base which comprises.
도 4 내지 도 7을 참조하면, 거리 측정 장치(130)는 베이스(131), 센서부(133), 하우징(134) 및 냉각 채널부(139)를 포함한다.4 to 7, the distance measuring device 130 includes a base 131, a sensor unit 133, a housing 134, and a cooling channel unit 139.
베이스(131)는 다각 패널 또는 원형 패널 형태로 형성될 수 있다. 베이스(131)는 베이스 플레이트(131a), 단열부재(131b) 및 서포터부재(131c)를 포함한다.The base 131 may be formed in the shape of a polygonal panel or a circular panel. The base 131 includes a base plate 131a, a heat insulating member 131b, and a supporter member 131c.
베이스 플레이트(131a)는 하우징(134)에 결합되어 하우징(134)의 내부 공간이 외부와 차폐되도록 한다. 즉, 베이스 플레이트(131a)는 개방된 하우징(134)의 내부 공간을 폐쇄한다. The base plate 131a is coupled to the housing 134 so that the inner space of the housing 134 is shielded from the outside. That is, the base plate 131a closes the inner space of the opened housing 134.
단열부재(131b)는 베이스 플레이트(131a)에 결합되고, 하우징(134)의 내부 공간 상에 배치된다. 단열부재(131b)는 단열 재질을 포함하여 이루어지고, 단열부재(131b) 상에는 센서부(133)가 고정된다. 이로써 하우징(134) 외부의 열에너지는 단열부재(131b)에 의해 하우징(1349) 내부로 유입되는 것이 차단되므로, 외부의 열에너지가 센서부(133)에 전달되는 것을 차단할 수 있다. 따라서 센서부(133)가 외부의 열에너지에 의해 가열되어 손상되거나 오작동 되는 것을 방지할 수 있다. The heat insulating member 131b is coupled to the base plate 131a and is disposed on an inner space of the housing 134. The heat insulating member 131b includes a heat insulating material, and the sensor unit 133 is fixed on the heat insulating member 131b. As a result, the heat energy outside the housing 134 is blocked from being introduced into the housing 1349 by the heat insulating member 131b, thereby preventing the heat energy from being transmitted to the sensor unit 133. Therefore, the sensor unit 133 may be prevented from being damaged or malfunctioned by being heated by external heat energy.
서포터부재(131c)는 단열부재(131b)에 세워지도록 설치된다. 서포터부재(131c)는 센서부(133)의 일측면에 결합되어 센서부(133)를 지지한다. 센서부(133)는 하면(도 5 기준)이 단열부재(131b)에 의해 지지되고, 일측면이 서포터부재(131c)에 의해 지지되므로, 맨드릴(120)에 압연 코일(C)이 감길 때에 가압부(150)를 통해 진동이 전달되더라도 센서부(133)는 본래의 위치에서 이탈되지 않게 된다. The supporter member 131c is installed to stand on the heat insulating member 131b. The supporter member 131c is coupled to one side of the sensor unit 133 to support the sensor unit 133. Since the lower surface (based on FIG. 5) of the sensor unit 133 is supported by the heat insulating member 131b and one side thereof is supported by the supporter member 131c, the sensor unit 133 is pressurized when the rolling coil C is wound around the mandrel 120. Even if vibration is transmitted through the unit 150, the sensor unit 133 is not separated from its original position.
센서부(133)는 베이스(131), 구체적으로 단열부재(131b)에 설치되고, 측정대상물인 맨드릴(120) 또는 맨드릴(120)에 권취된 압연 코일(C)에 광을 조사한다. 센서부(133)는 맨드릴(120)의 세그먼트부재(124) 또는 맨드릴(120)에 권취된 압연 코일(C)에 레이저를 조사하는 레이저 센서일 수 있다. 센서부(133)는 광을 조사하여 맨드릴(120) 외측면 또는 맨드릴(120)에 권취된 압연 코일(C)의 표면까지의 거리를 측정하는 한 다양한 형태가 적용될 수 있다.The sensor unit 133 is installed on the base 131, specifically, the heat insulating member 131b, and irradiates light onto the mandrel 120 or the rolling coil C wound around the mandrel 120. The sensor unit 133 may be a laser sensor for irradiating a laser to the segment member 124 of the mandrel 120 or the rolling coil C wound around the mandrel 120. The sensor unit 133 may be applied in various forms as long as the sensor unit 133 measures the distance to the outer surface of the mandrel 120 or the surface of the rolling coil C wound on the mandrel 120.
하우징(134)은 베이스(131)에 결합된다. 이때 하우징(134)의 내부 공간은 베이스(131)에 의해 외부와 차폐된다. 따라서 하우징(134) 내부에 배치되는 센서부(133)는 하우징(134) 외부의 습기, 열에너지, 이물질 등으로부터 보호된다. 이로써 센서부(133)가 외부의 습기, 열에너지 또는 이물질 등에 의해 손상되는 것을 방지할 수 있다.The housing 134 is coupled to the base 131. At this time, the inner space of the housing 134 is shielded from the outside by the base 131. Therefore, the sensor unit 133 disposed inside the housing 134 is protected from moisture, heat energy, foreign matters, and the like outside the housing 134. As a result, the sensor unit 133 may be prevented from being damaged by external moisture, thermal energy or foreign matter.
하우징(134)은 구획판부(137)와 배기 포트(138)를 더 포함한다. The housing 134 further includes a partition plate portion 137 and an exhaust port 138.
구획판부(137)는 하우징(134)의 내부 공간에 배치되어 하우징(134)의 내부 공간을 구획한다. 이때 구획판부(137)는 하우징(134)의 내부 공간을 센서부(133)가 배치되는 공간과, 센서부(133)가 배치되지 않은 공간으로 구획한다. 이와 같이 구획판부(137)가 하우징(134)의 내부 공간을 구획하므로, 외부의 열에너지가 센서부(133) 측으로 유입되는 것을 한층 더 차폐할 수 있다. The partition plate part 137 is disposed in the interior space of the housing 134 and partitions the interior space of the housing 134. In this case, the partition plate 137 divides the internal space of the housing 134 into a space in which the sensor unit 133 is disposed and a space in which the sensor unit 133 is not disposed. In this way, since the partition plate 137 partitions the inner space of the housing 134, it is possible to further shield that external heat energy flows into the sensor unit 133.
구획판부(137)는 하우징(134)의 내부 공간을 구획하므로, 하우징(134)에서 맨드릴(120)에 가까운 부분과 먼 부분을 공간적으로 분할할 수 있다. 따라서 맨드릴(120)에 의해 가까운 부분이 가열되더라도 맨드릴(120)에서 먼 부분으로 열기가 전달되는 것을 줄일 수 있다. 하우징(134)에서 맨드릴(120)에서 먼 부분의 내부 공간은 실질적으로 열차단 버퍼로 기능한다.Since the partition plate part 137 partitions the inner space of the housing 134, the partition plate 137 may spatially divide a portion close to the mandrel 120 from the housing 134. Therefore, even if the close part is heated by the mandrel 120, it is possible to reduce the heat transfer from the mandrel 120 to the far part. The inner space of the portion distant from the mandrel 120 in the housing 134 substantially functions as a thermal barrier buffer.
구획판부(137)에는 센서부(133)에서 조사되는 광(L)이 통과할 수 있도록 통과홀부(137a)가 형성된다. 구획판부(137)에 통과홀부(137a)가 형성되므로, 센서부(133)에서 조사되는 광(L)이 구획판부(137)에 의해 막히지 않고 원활하게 세그먼트부재(124)에 도달되도록 할 수 있다.In the partition plate portion 137, a passage hole portion 137a is formed to allow the light L emitted from the sensor portion 133 to pass therethrough. Since the through hole part 137a is formed in the partition plate part 137, the light L irradiated from the sensor part 133 may be smoothly reached by the partition plate part 137 and reach the segment member 124. .
배기 포트(138)는 베이스(131)가 배치되는 반대 측에 설치된다. 본 실시예의 도 6에 도시된 바와 같이 베이스(131)가 하우징(134)의 하부측에 설치되므로, 배기 포트(138)는 그 반대 편인 상부측에 설치된다. 하우징(134)의 배기 포트(138)는 하우징(134)의 내부 공간에 존재하는 공기를 외부로 배출시킨다. 하우징(134)의 내부 공기가 배기 포트(138)에 의해 외부로 배출되므로, 센서부(133)가 하우징(134)의 내부에서 가열된 공기에 의해 열화되는 것을 억제할 수 있다. The exhaust port 138 is installed on the opposite side where the base 131 is disposed. Since the base 131 is installed on the lower side of the housing 134 as shown in FIG. 6 of this embodiment, the exhaust port 138 is provided on the upper side opposite to it. The exhaust port 138 of the housing 134 discharges air existing in the internal space of the housing 134 to the outside. Since the internal air of the housing 134 is discharged to the outside by the exhaust port 138, the sensor unit 133 can be suppressed from being deteriorated by the air heated in the housing 134.
배기 포트(138)의 내부에는 하우징(134)의 내부 압력이 일정 압력 이상이 될 때에 배기 포트(138)를 개방시키도록 체크 밸브(미도시)가 설치될 수 있다.Inside the exhaust port 138, a check valve (not shown) may be installed to open the exhaust port 138 when the internal pressure of the housing 134 becomes higher than a predetermined pressure.
하우징(134)은 베이스(131)에 결합되는 제1 하우징(135)과, 제1 하우징(135)에 결합되는 제2 하우징(136)을 포함한다. 제1 하우징(135)의 외경은 제2 하우징(136)의 외경보다 크게 형성될 수 있다. 이때 구획판부(137)는 제1 하우징(135)과 제2 하우징(136) 사이에 배치되어 제1 하우징(135)과 제2 하우징(136)의 내부 공간을 구획할 수 있다. 또한 배기 포트(138)는 제2 하우징(136)에 설치될 수 있다. The housing 134 includes a first housing 135 coupled to the base 131, and a second housing 136 coupled to the first housing 135. The outer diameter of the first housing 135 may be larger than the outer diameter of the second housing 136. In this case, the partition plate part 137 may be disposed between the first housing 135 and the second housing 136 to partition an internal space of the first housing 135 and the second housing 136. In addition, the exhaust port 138 may be installed in the second housing 136.
제1 하우징(135)은 베이스(131)와 함께 센서부(133)가 설치되는 공간을 외부로부터 차폐시키고, 제2 하우징(136)은 제1 하우징(135)의 상단부(도 6 기준) 측에 열차단 공간을 형성한다. 따라서 센서부(133)는 베이스(131)에 의해 외부의 열에너지가 하측에서 유입되는 것을 차단할 수 있고, 제1 하우징(135)에 의해 외부의 열에너지가 측부에서 유입되는 것을 차단할 수 있으며, 제2 하우징(136) 및/또는 구획판부(137)에 의해서 외부의 열에너지가 상측에서 유입되는 것을 차단할 수 있다. The first housing 135 shields the space where the sensor unit 133 is installed together with the base 131 from the outside, and the second housing 136 is located at the upper end (see FIG. 6) of the first housing 135. Form a thermal barrier space. Therefore, the sensor unit 133 may block external heat energy from flowing in by the base 131 from the lower side, block external heat energy from flowing in from the side by the first housing 135, and the second housing. 136 and / or the partition plate portion 137 may block external heat energy from flowing from above.
또한 제2 하우징(136)에는 구획판부(137)의 통과홀부(137a)에 대응되도록 통과홀부(136a)가 형성된다. 제2 하우징(136)의 통과홀부(136a)와 구획판부(137)의 통과홀부(137a)는 센서부(133)에서 조사되는 광(L)의 진행 경로 상에 형성된다. 센서부(133)는 제1 하우징(135)과 제2 하우징(136)에 의해 외부로부터 보호되고, 센서부(133)에서 조사되는 광(L)은 2개의 통과홀부(136a,137a)를 통과한 후 세그먼트부재(124)에 도달될 수 있다.In addition, a passage hole 136a is formed in the second housing 136 to correspond to the passage hole 137a of the partition plate 137. The passage hole portion 136a of the second housing 136 and the passage hole portion 137a of the partition plate portion 137 are formed on the traveling path of the light L irradiated from the sensor portion 133. The sensor unit 133 is protected from the outside by the first housing 135 and the second housing 136, and the light L irradiated from the sensor unit 133 passes through the two through holes 136a and 137a. The segment member 124 may then be reached.
냉각 채널부(139)는 베이스(131)와 하우징(134)에 배치된다. 냉각 채널부(139)는 냉각 매체가 유동되도록 유로를 형성한다. 냉각 매체가 냉각 채널부(139)를 따라 유동됨에 따라 베이스(131)와 하우징(134)이 냉각된다. 냉각 매체로는 냉각수, 냉각 오일 등이 적용될 수 있다. The cooling channel portion 139 is disposed in the base 131 and the housing 134. The cooling channel part 139 forms a flow path so that the cooling medium flows. As the cooling medium flows along the cooling channel portion 139, the base 131 and the housing 134 cool. As the cooling medium, cooling water, cooling oil, or the like may be applied.
냉각 채널부(139)는 하우징(134)과 베이스(131)에 나선 형태로 배치된다. 따라서 냉각 채널부(139)와 하우징(134), 그리고 냉각 채널부(!39)와 베이스(131)간의 열접촉 면적을 증가시킬 수 있어 하우징(134)과 베이스(131)의 냉각 효율을 향상시킬 수 있다.The cooling channel part 139 is disposed in the form of a spiral in the housing 134 and the base 131. Therefore, the thermal contact area between the cooling channel portion 139 and the housing 134 and the cooling channel portion! 39 and the base 131 can be increased to improve the cooling efficiency of the housing 134 and the base 131. Can be.
하우징(134)은 냉각 매체에 의해 냉각됨과 아울러 하우징(134) 내부의 공기가 외부로 배출됨에 의해 냉각된다. 따라서 하우징(134)은 2가지 냉각 매체에 의해 냉각될 수 있다.The housing 134 is cooled by the cooling medium as well as the air inside the housing 134 is discharged to the outside. Thus, the housing 134 can be cooled by two cooling media.
냉각 채널부(139)는 베이스(131), 구체적으로 베이스 플레이트(131a)에 배치되는 제1 냉각 채널부(139a)와, 하우징(134)에 배치되는 제2 냉각 채널부(139b)를 포함한다. 제1 냉각 채널부(139a)가 베이스(131)에 코일 형태 등 다양하게 배치되므로, 센서부(133)가 설치되는 베이스(131)를 냉각 매체에 의해 직접 냉각시킬 수 있다. 제2 냉각 채널부(139b)는 하우징(134)의 둘레를 따라 나선 형태로 배치되어 하우징(134)을 냉각시키므로, 하우징(134) 내부에 배치되는 센서부(133)가 가열되는 것을 방지할 수 있다.The cooling channel portion 139 includes a base 131, specifically, a first cooling channel portion 139a disposed on the base plate 131a, and a second cooling channel portion 139b disposed on the housing 134. . Since the first cooling channel part 139a is disposed in the base 131 in various ways such as a coil shape, the base 131 on which the sensor part 133 is installed may be directly cooled by a cooling medium. The second cooling channel part 139b is disposed in a spiral form along the circumference of the housing 134 to cool the housing 134, thereby preventing the sensor part 133 disposed inside the housing 134 from being heated. have.
제2 냉각 채널부(139b)는 제1 하우징(135)에만 설치될 수 있다. 따라서 제1 하우징(135)의 내부 공간은 냉각수 또는 냉각 오일 등의 유체에 의해 냉각되고, 제2 하우징(136)의 내부 공간은 공기와 같이 기체에 의해 냉각되도록 할 수 있다. 이처럼 제1 하우징(135)과 제2 하우징(136)이 서로 다른 냉각 매체에 의해 냉각되므로, 냉각 구간이 냉각 매체에 따라 분할될 수 있다.The second cooling channel unit 139b may be installed only in the first housing 135. Therefore, the inner space of the first housing 135 may be cooled by a fluid such as cooling water or cooling oil, and the inner space of the second housing 136 may be cooled by a gas such as air. As such, since the first housing 135 and the second housing 136 are cooled by different cooling media, the cooling section may be divided according to the cooling media.
또한 제2 냉각 채널부(139b)는 제1 하우징(135)과 제2 하우징(136)에 모두 설치될 수 있음은 물론이다.In addition, the second cooling channel unit 139b may be installed in both the first housing 135 and the second housing 136.
상기와 같이 구성된 본 발명에 따른 압연 코일용 권취 장치의 작동에 관해 설명하기로 한다.The operation of the winding device for a rolling coil according to the present invention configured as described above will be described.
도 8은 본 발명의 일 실시예에 따른 압연 코일용 권취 장치에서 맨드릴에 압연 코일이 감기는 상태를 도시한 정면도이고, 도 9는 본 발명의 일 실시예에 따른 압연 코일용 권취 장치에서 맨드릴의 세그먼트부재가 외측으로 팽창된 상태를 도시한 단면도이다.8 is a front view illustrating a state in which a rolling coil is wound around a mandrel in a winding device for a rolling coil according to an embodiment of the present invention, and FIG. 9 is a view of the mandrel in a winding device for a rolling coil according to an embodiment of the present invention. It is sectional drawing which shows the state which the segment member expanded outward.
도 8 및 도 9를 참조하면, 압연기(미도시)에서 스트립을 압연하여 압연 코일(C)을 형성한다. 압연 코일(C)은 이송 롤러(미도시)를 따라 이송되어 코일 유입부(111)에 유입된다. 압연 코일(C)은 코일 유입부(111)에서 핀치 롤러(114)에 의해 맨드릴(120) 측으로 안내된다. 8 and 9, the strip is rolled in a rolling mill (not shown) to form a rolling coil (C). The rolling coil C is conveyed along the conveying roller (not shown) and flows into the coil inlet 111. The rolling coil C is guided to the mandrel 120 by the pinch roller 114 at the coil inlet 111.
가압부(150)의 가압 프레임(153)은 맨드릴(120)의 세그먼트부재(124) 근처에 배치된다. 이때 가압 롤러(155)는 세그먼트부재(124)의 외주면과 일정 간격 이격되게 배치된다. 가압 롤러(155)와 세그먼트부재(124)는 맨드릴(120)에서 권취될 압연 코일(C)의 종류나 두께 등에 따라 변경될 수 있다.The pressing frame 153 of the pressing unit 150 is disposed near the segment member 124 of the mandrel 120. At this time, the pressure roller 155 is disposed to be spaced apart from the outer peripheral surface of the segment member 124 by a predetermined interval. The pressure roller 155 and the segment member 124 may be changed according to the type or thickness of the rolling coil C to be wound on the mandrel 120.
맨드릴(120)이 회전됨에 따라 핀치 롤러(114)에서 공급되는 압연 코일(C)이 맨드릴(120)에 감긴다. 가압 롤러(155)는 압연 코일(C)이 감김에 따라 압연 코일(C)과 구름 접촉한다. 맨드릴(120)에 압연 코일(C)이 2 ~ 5 바퀴 정도 감기면, 이동장치(128)의 로드(128a)가 실린더(128b)에 인입된다. 이때 맨드릴 바디(121)가 세그먼트부재(124)에서 이동됨에 따라 세그먼트부재(124)의 외경이 확대되므로, 맨드릴(120)에 감긴 압연 코일(C)이 팽팽하게 팽창된다. 맨드릴(120)에 감긴 압연 코일(C)이 팽팽해지므로, 감긴 압연 코일(C)의 외경이 균일해짐에 따라 압연 코일(C)이 맨드릴(120)에 밀착된 상태로 감기게 된다.As the mandrel 120 is rotated, the rolling coil C supplied from the pinch roller 114 is wound on the mandrel 120. The pressure roller 155 is in rolling contact with the rolling coil C as the rolling coil C is wound. When the rolling coil C is wound about 2 to 5 turns on the mandrel 120, the rod 128a of the moving device 128 is introduced into the cylinder 128b. At this time, since the outer diameter of the segment member 124 is enlarged as the mandrel body 121 is moved from the segment member 124, the rolling coil C wound around the mandrel 120 is expanded in tension. Since the rolling coil C wound around the mandrel 120 is tightened, as the outer diameter of the wound rolling coil C becomes uniform, the rolling coil C is wound in a state of being in close contact with the mandrel 120.
맨드릴(120)이 계속적으로 회전됨에 따라 맨드릴(120)에 감긴 압연 코일(C)의 직경도 점차적으로 커지게 된다. 이때 가압 피스톤(151)이 힌지부(151c)를 중심으로 맨드릴(120)에서 멀어지도록 회전되고, 가압 로드(151b)가 가압 실린더(151a)로 인입된다. 따라서 가압 롤러(155)는 맨드릴(120)에 감긴 압연 코일(C)의 직경이 커짐에 따라 맨드릴(120)에서 멀어진다.As the mandrel 120 is continuously rotated, the diameter of the rolling coil C wound on the mandrel 120 also gradually increases. At this time, the pressure piston 151 is rotated away from the mandrel 120 about the hinge portion 151c, and the pressure rod 151b is drawn into the pressure cylinder 151a. Therefore, the pressure roller 155 moves away from the mandrel 120 as the diameter of the rolling coil C wound on the mandrel 120 increases.
맨드릴(120)이 압연 코일(C)을 감는 동안에 압연 코일(C)의 열기가 맨드릴(120), 가압부(150) 및 거리 측정 장치(130)에 계속적으로 전달된다. 이때 거리 측정 장치(130)는 아래와 같이 냉각 매체에 의해 냉각된다.The heat of the rolling coil C is continuously transmitted to the mandrel 120, the pressing unit 150, and the distance measuring device 130 while the mandrel 120 is winding the rolling coil C. At this time, the distance measuring device 130 is cooled by the cooling medium as follows.
냉각 채널부(139)에 냉각 매체가 유동됨에 따라 하우징(134)과 베이스(131)가 냉각된다. 제1 냉각 채널부(139a)는 베이스(131)에 배치되어 베이스(131)를 냉각하고, 제2 냉각 채널부(139b)는 하우징(134)에 설치되어 하우징(134)을 냉각한다. As the cooling medium flows in the cooling channel portion 139, the housing 134 and the base 131 are cooled. The first cooling channel part 139a is disposed in the base 131 to cool the base 131, and the second cooling channel part 139b is installed in the housing 134 to cool the housing 134.
구획판부(137)는 하우징(134)의 내부 공간을 센서부(133)가 배치되는 공간과, 센서부(133)가 배치되지 않은 공간으로 구획한다(도 6 참조). 구획판부(137)가 하우징(134)의 내부 공간을 구획하므로, 외부의 열에너지 특히 제2 하우징(136)측의 열에너지가 제2 하우징(136), 구획판부(137)를 통해 센서부(133) 측으로 유입되는 것을 차폐할 수 있다. 또한 구획판부(137)는 하우징(134)의 내부 공간을 구획하므로, 하우징(134)에서 맨드릴(120)에 가까운 부분과 먼 부분을 공간적으로 분할할 수 있다. 따라서 맨드릴(120)에 의해 가까운 부분이 가열되더라도 맨드릴(120)에서 먼 부분으로 열기가 전달되는 것을 줄일 수 있다. The partition plate part 137 divides the internal space of the housing 134 into the space in which the sensor part 133 is arrange | positioned, and the space in which the sensor part 133 is not arrange | positioned (refer FIG. 6). Since the partition plate part 137 partitions the inner space of the housing 134, the external heat energy, in particular, the heat energy of the second housing 136 side, passes through the second housing 136 and the partition plate part 137. It can shield the inflow to the side. In addition, since the partition plate part 137 partitions the internal space of the housing 134, a part closer to the mandrel 120 and a part farther from the housing 134 may be spatially divided. Therefore, even if the close part is heated by the mandrel 120, it is possible to reduce the heat transfer from the mandrel 120 to the far part.
배기 포트(138)는 하우징(134)의 내부 공간에 존재하는 공기를 외부로 배출시킨다. 하우징(134)의 내부 공기가 배기 포트(138)에 의해 외부로 배출되므로, 센서부(133)가 하우징(134)의 내부에서 가열된 공기에 의해 열화되는 것을 줄일 수 있다. The exhaust port 138 discharges air existing in the internal space of the housing 134 to the outside. Since the air inside the housing 134 is discharged to the outside by the exhaust port 138, it is possible to reduce the deterioration of the sensor unit 133 by the air heated in the inside of the housing 134.
도 10은 본 발명의 일 실시예에 따른 압연 코일용 권취 장치에서 맨드릴에 압연 코일이 더 감긴 상태를 도시한 구성도이고, 도 11은 본 발명의 일 실시예에 따른 압연 코일용 권취 장치에서 맨드릴의 세그먼트부재가 수축된 상태를 도시한 단면도이다.10 is a view illustrating a state in which a rolling coil is further wound on a mandrel in a winding device for a rolling coil according to an embodiment of the present invention, and FIG. 11 is a mandrel in a winding device for a rolling coil according to an embodiment of the present invention. It is sectional drawing which shows the state which the segment member of the contracted | contracted.
도 10 및 도 11을 참조하면, 압연 코일(C)의 권취 공정이 완료되면, 코일 이송 장치(170)의 승강 피스톤(176)이 승강부(174)를 상승시킨다. 승강부(174)가 상승됨에 따라 권취된 압연 코일(C)을 지지하게 된다. 이동 장치(128)의 로드(128a)가 실린더(128b)에서 인출됨에 따라 맨드릴 바디(121)의 경사면부(122)가 세그먼트부재(124)의 접촉면부(125)와 슬라이딩되면서 이동된다. 이때 경사면부(122)가 접촉면부(125) 폭이 넓어지는 측으로 이동됨에 따라 세그먼트부재(124)가 맨드릴 바디(121)의 중심부 측으로 이동된다. 따라서 세그먼트부재(124)의 외경이 축소되므로, 권취된 압연 코일(C)이 맨드릴(120)로부터 용이하게 분리될 수 있다. 10 and 11, when the winding process of the rolling coil C is completed, the lifting piston 176 of the coil transport device 170 raises the lifting unit 174. As the lifting unit 174 is raised to support the rolled coil (C). As the rod 128a of the moving device 128 is withdrawn from the cylinder 128b, the inclined surface portion 122 of the mandrel body 121 is moved while sliding with the contact surface portion 125 of the segment member 124. At this time, as the inclined surface portion 122 is moved to the side where the contact surface portion 125 is widened, the segment member 124 is moved to the center side of the mandrel body 121. Therefore, since the outer diameter of the segment member 124 is reduced, the rolled coil C may be easily separated from the mandrel 120.
권취된 압연 코일(C)이 적재된 압연 코일 이송 장치(170)가 레일(117)을 따라 이동됨에 따라 압연 코일(C)은 맨드릴(120)로부터 분리된 후 압연 코일용 권취 장치의 외부로 배출된다.As the rolled coil transfer device 170 on which the rolled coiled coil C is loaded is moved along the rail 117, the rolled coil C is separated from the mandrel 120 and then discharged to the outside of the winding device for the rolled coil. do.
도 12는 본 발명의 일 실시예에 따른 압연 코일용 권취 장치에서 맨드릴의 세그먼트부재가 변형된 상태를 도시한 단면도이고, 도 13은 본 발명의 일 실시예에 따른 압연 코일용 권취 장치에서 맨드릴의 세그먼트부재가 변형되었을 때에 거리 감지 장치가 세그먼트부재의 거리를 측정하는 상태를 도시한 정면도이다.12 is a cross-sectional view illustrating a state in which a segment member of a mandrel is deformed in a winding device for a rolling coil according to an embodiment of the present invention, and FIG. 13 is a view of the mandrel in a winding device for a rolling coil according to an embodiment of the present invention. It is a front view which shows the state in which the distance sensing apparatus measures the distance of a segment member when a segment member is deformed.
도 12 및 도 13을 참조하면, 맨드릴(120)에서 권취된 압연 코일(C)이 분리된 후 맨드릴(120)이 회전되면서 냉각 유체에 의해 냉각된다. 대략 600° 정도의 압연 코일(C)이 맨드릴(120)에 귄취되는 동안에 맨드릴(120)과 가압부(150)가 가열된다.12 and 13, after the rolling coil C wound around the mandrel 120 is separated, the mandrel 120 is rotated and cooled by a cooling fluid. The mandrel 120 and the pressurizing part 150 are heated while the rolling coil C of approximately 600 degrees is picked up by the mandrel 120.
맨드릴(120)이 가열됨에 따라 세그먼트부재(124)가 열변형될 수 있다. 이때 세그먼트부재(124)의 중심부는 세그먼트부재(124)의 양측부보다 열접촉 면적이 좁게 형성되므로, 세그먼트부재(124)의 중심부에서 열변형 정도가 상대적으로 커진다. 또한 맨드릴(120)이 회전되는 동안에 세그먼트부재(124)에는 원심력이 작용하게 된다. 이때 세그먼트부재(124)의 양측부가 링크부재(127)에 의해 결합되므로, 세그먼트부재(124)의 중심부가 외측으로 약간 볼록하게 변형된다. 이처럼 세그먼트부재(124)는 열과 원심력에 의해 중심부의 외경이 양측부보다 커지도록 변형된다. As the mandrel 120 is heated, the segment member 124 may be thermally deformed. At this time, the center of the segment member 124 is formed in a narrower thermal contact area than both sides of the segment member 124, the degree of thermal deformation at the center of the segment member 124 is relatively large. In addition, centrifugal force is applied to the segment member 124 while the mandrel 120 is being rotated. At this time, since both side portions of the segment member 124 are coupled by the link member 127, the center portion of the segment member 124 is slightly convexly deformed outward. Thus, the segment member 124 is deformed so that the outer diameter of the center portion is larger than both sides by heat and centrifugal force.
센서부(133)는 세그먼트부재(124)의 외측면에 광(L)을 주사함에 의해 세그먼트부재(124)와 센서부(133) 사이의 거리를 측정한다. 제어부(160)는 세그먼트부재(124)가 열과 원심력에 의해 변형됨에 따라 세그먼트부재(124)의 외경이 확대되었다고 판단되면, 가압 피스톤(151)을 구동함에 의해 가압 롤러(155)와 세그먼트부재(124)의 외측면의 간격을 일정하게 유지한다. 따라서 맨드릴(120)이 압연 코일(C)이 권취되지 않은 상태로 회전될 때에, 세그먼트부재(124)가 가압 롤러(155)에 접촉되는 것을 방지할 수 있어, 세그먼트부재(124)와 가압 롤러(155)가 각각 손상되는 것을 차단할 수 있다.The sensor unit 133 measures the distance between the segment member 124 and the sensor unit 133 by scanning the light L on the outer surface of the segment member 124. When the controller 160 determines that the outer diameter of the segment member 124 is enlarged as the segment member 124 is deformed by heat and centrifugal force, the controller 160 drives the pressure roller 155 and the segment member 124 by driving the pressure piston 151. The distance between the outer surfaces of the c) is kept constant. Therefore, when the mandrel 120 is rotated without the rolling coil C being wound, the segment member 124 can be prevented from contacting the pressure roller 155, so that the segment member 124 and the pressure roller ( 155 can be prevented from damaging each other.
