  Hereinafter, an embodiment of a rolling coil winding device according to the present invention will be described with reference to the accompanying drawings. In the process of describing the rolling coil winding device, the thicknesses of the lines and the sizes of the components shown in the drawings may be exaggerated for the sake of clarity and convenience. Moreover, the term mentioned later is a term defined in consideration of the function in this invention, and this may differ with the intention of a user, an operator, or a custom. Therefore, the definitions for these terms must be made based on the contents throughout this specification.

  FIG. 1 is a configuration diagram showing a rolling coil winding device according to an embodiment of the present invention, and FIG. 2 is a sectional view showing a mandrel in the rolling coil winding device according to an embodiment of the present invention. FIG. 3 is a front view showing a mandrel and a pressure unit in the rolling coil winding device according to the embodiment of the present invention.

  1 to 3, the rolling coil winding device according to an embodiment of the present invention includes a mandrel 120, a pressure unit 150, a distance measuring device 130, and a control unit 160.

  The rolling coil winding device includes a winding body 110, and a coil inflow portion 111 is formed in the winding body 110 so that the rolling coil C flows therein. The coil inflow portion 111 is formed with a guide portion 113 that guides the rolling coil C to the mandrel 120 side. The guide part 113 includes a pinch roller 114 that supports both side surfaces of the rolling coil C when the rolling coil C moves to the mandrel 120 side. The pinch roller 114 rotates while being in rolling contact with both side surfaces of the rolling coil C.

  The mandrel 120 is rotatably provided on the winding body 110 so that the rolling coil C is wound thereon. The mandrel 120 includes a mandrel body 121, a segment member 124, a link member 127, and a moving device 128.

  The mandrel body 121 is rotatably provided on the winding body 110. On the outer surface of the mandrel body 121, an inclined surface portion 122 is disposed along the circumferential direction. A plurality of inclined surface portions 122 are formed on the outer surface of the mandrel body 121. At this time, the inclined surface portions 122 are arranged in a row along the longitudinal direction of the mandrel body 121 (the left-right direction in FIG. 2). Although FIG. 3 shows a structure in which the inclined surface portions 122 are arranged in four rows along the longitudinal direction of the mandrel body 121 (left-right direction in FIG. 2), the number of rows of the inclined surface portions 122 can be variously changed. .

  On the inner side surface of the segment member 124, a plurality of contact surface portions 125 formed to be inclined are formed. The contact surface portions 125 are formed so as to form a row along the longitudinal direction of the segment member 124 (the left-right direction in FIG. 2). The contact surface portion 125 corresponds to the inclined surface portion 122 of the mandrel body 121 on a one-to-one basis. The segment members 124 have a one-to-one correspondence with the rows of the inclined surface portions 122 formed along the longitudinal direction of the mandrel body 121. When the inclined surface portions 122 are arranged in four rows along the longitudinal direction of the mandrel body 121, four segment members 124 are provided.

  The link member 127 links the segment member 124 and the mandrel body 121 to each other. The link member 127 allows the segment member 124 to move within a certain distance range along the longitudinal direction of the mandrel body 121. When the mandrel body 121 moves relative to the segment member 124, the inclined surface portion 122 of the mandrel body 121 moves while sliding with the contact surface portion 125 of the segment member 124. At this time, since the segment member 124 is far from or near the center of the mandrel body 121, the outer diameter of the segment member 124 is enlarged or reduced.

  The moving device 128 is connected to the mandrel body 121. The mandrel body 121 moves relative to the segment member 124 by the operation of the moving device 128. Thereby, when the moving device 128 is operated, the outer diameter of the segment member 124 can be enlarged and reduced.

  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. When the fluid is supplied to the cylinder 128b, the rod 128a is pulled out from the cylinder 128b, and when the fluid is discharged from the cylinder 128b, the rod 128a is pulled into the cylinder 128b. As the rod 128a moves, the mandrel body 121 moves in the left-right direction (reference to FIG. 2).

  A plurality of pressurizing units 150 are arranged on the periphery of the mandrel 120. The pressurizing unit 150 pressurizes the rolling coil C wound around the mandrel 120. The pressure unit 150 includes a pressure piston 151, a pressure frame 153, and a pressure roller 155.

  The pressurizing piston 151 is rotatably provided around the mandrel 120 on the winding body 110 by a hinge portion 151c. The pressure piston 151 includes a pressure cylinder 151a and a pressure rod 151b. When the fluid is supplied to the pressure cylinder 151a, the pressure rod 151b is pulled out from the pressure cylinder 151a, and when the fluid is discharged from the pressure cylinder 151a, the pressure rod 151b is inside the pressure cylinder 151a. Be drawn into.

  The pressure frame 153 is coupled to the pressure rod 151 b of the pressure piston 151. A distance measuring device 130 is disposed on the pressure frame 153. The space between the pressure frame 153 and the segment member 124 of the mandrel 120 is adjusted by pulling the pressure rod 151b in or out of the pressure cylinder 151a.

  The pressure roller 155 is disposed on one surface of the pressure frame 153, specifically, on the surface facing 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, a fluid is supplied to the pressure cylinder 151a, whereby the pressure rod 151b is pulled out from the pressure cylinder 151a. The pressure rod 151b is pulled out from the pressure cylinder 151a until the pressure roller 155 contacts the rolling coil C. Therefore, when the rolling coil C is wound around the mandrel 120, the pressure roller 155 rotates while being in rolling contact with the rolling coil C.

  The distance measuring device 130 is provided in the pressure unit 150. At this time, the distance measuring device 130 may be provided for each pressurizing unit 150 or may be provided for only one pressurizing 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 mandrel 120 or a rolled coil C wound around the mandrel 120. Therefore, when the measuring object is the mandrel 120, the distance measuring device 130 measures the distance from the mandrel 120 to the distance measuring device 130, and when the measuring object is the rolled coil C wound around the mandrel 120, the distance measuring device. 130 measures the distance from the rolling coil C to the distance measuring device 130.

  The distance measuring device 130 is cooled by the cooling medium. Therefore, even if the distance measuring device 130 is provided at a close distance to the mandrel 120 or the rolling coil C, it can be prevented from being damaged by the hot air generated in the mandrel 120 or the rolling coil C.

  The control unit 160 adjusts the distance between the pressurization unit 150 and the mandrel 120 or the pressurization unit 150 and the rolling coil C wound around the mandrel 120 according to the distance measured by the distance measurement device 130. The distance measuring device 130 can measure in real time the distance between the mandrel 120 and the pressing unit 150 or the distance between the rolling coil C wound around the mandrel 120 and the pressing unit 150. Based on the obtained value, the controller 160 adjusts the interval between the pressurizing unit 150 and the mandrel 120 or the interval between the pressurizing unit 150 and the rolling coil C wound around the mandrel 120. Can do.

  Thus, since the space | interval between the pressurization part 150 and the rolling coil C wound around the mandrel 120 of the measuring object or the mandrel 120 is adjusted in real time, the rolling coil C is wound around the mandrel 120. Before, the pressure roller 155 of the pressure unit 150 can be prevented from coming into contact with the mandrel 120 to damage the pressure roller 155. After the rolling coil C is wound around the mandrel 120, It is possible to prevent the pressing roller 155 or the rolling coil C from being damaged by the pressing roller 155 of the pressing unit 150 excessively pressing the rolling coil C.

  The control unit 160 can appropriately adjust the interval between the mandrel 120 and the pressure unit 150 according to the thickness of the rolling coil C wound around the mandrel 120. That is, the control unit 160 determines the distance from the surface of the rolling coil C measured by the distance measuring device 130 and controls the pressurizing piston 151 to adjust the interval between the mandrel 120 and the pressurizing unit 150. To do. As a result, the pressure roller 155 of the pressure unit 150 can be separated from the mandrel 120 by an amount corresponding to an increase in the thickness of the rolling coil C wound around the mandrel 120, so that the thickness of the rolling coil C is changed. Even in this case, the pressure roller 155 can press the rolling coil C with a constant pressure. In other words, since the distance to the rolling coil C wound around the mandrel 120 can be measured in real time by the distance measuring device 130, the position of the pressure roller 155 is adjusted in response to the thickness change of the rolling coil C immediately. It can be done.

  A rail 117 is disposed below the mandrel 120. A coil transfer device 170 is provided on the rail 117 so that the rolled rolling coil C can be mounted and transferred.

  The coil transfer device 170 is arranged on both sides of the frame 171, the drive wheel 172 that rotates along the rail 117, an elevating part 174 that can be raised and lowered on the frame 171, and an elevating part that raises and lowers the elevating part 174. It includes a piston 176 and a roller 177 that is disposed on the upper side of the elevating part 174 and supports the rolled coil C wound up.

  When the rolling coil C wound around the roller 177 is mounted, the elevating part 174 is lowered by the elevating piston 176. Subsequently, by driving the drive wheel 172, the rolling coil C is moved to the outside while the rolling coil transfer device 170 is being transferred to the outside of the rolling coil winding device.

  FIG. 4 is a perspective view showing a distance measuring device in the rolling coil winding device according to one embodiment of the present invention, and FIG. 5 is a distance measuring method in the rolling coil winding device according to one embodiment of the present invention. FIG. 6 is an exploded perspective view showing the apparatus, FIG. 6 is a cross-sectional view showing a distance measuring device in a rolling coil winding device according to an embodiment of the present invention, and FIG. It is a perspective view which shows the base which comprises the distance measuring apparatus in the winding apparatus for rolling coils.

  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.

  The base 131 may be formed as a polygon panel or a circular panel. The base 131 includes a base plate 131a, a heat insulating member 131b, and a supporter member 131c.

  The base plate 131a is coupled to the housing 134 so that the internal space of the housing 134 is shielded from the outside. That is, the base plate 131a closes the open internal space of the housing 134.

  The heat insulating member 131 b is coupled to the base plate 131 a and is disposed on the internal 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 flowing into the housing 134 by the heat insulating member 131 b, so that the external heat energy can be blocked from being transmitted to the sensor unit 133. Therefore, it is possible to prevent the sensor unit 133 from being damaged or malfunctioning by being heated by the external thermal energy.

  The supporter member 131c is provided to stand on the heat insulating member 131b. The supporter member 131 c is coupled to one side surface of the sensor unit 133 and supports the sensor unit 133. Since the sensor unit 133 has a lower surface (reference to FIG. 5) supported by the heat insulating member 131b and one side surface supported by the support member 131c, vibration is transmitted through the pressure unit 150 when the rolling coil C is wound around the mandrel 120. Even if this is done, the sensor unit 133 will not leave the original position.

  The sensor unit 133 is provided on the base 131, specifically, the heat insulating member 131 b, and irradiates light to the mandrel 120 of the measurement object or the rolling coil C wound around the mandrel 120. The sensor unit 133 may be a laser sensor that irradiates the segment member 124 of the mandrel 120 or the rolling coil C wound around the mandrel 120 with a laser. As long as the sensor part 133 irradiates light and measures the distance to the outer surface of the mandrel 120 or the surface of the rolling coil C wound around the mandrel 120, various forms are applicable.

  The housing 134 is coupled to the base 131. At this time, the internal 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 matter, and the like outside the housing 134. Accordingly, it is possible to prevent the sensor unit 133 from being damaged by external moisture, thermal energy, foreign matter, or the like.

  The housing 134 further includes a partition plate portion 137 and an exhaust port 138.

  The partition plate portion 137 is disposed in the internal space of the housing 134 and partitions the internal space of the housing 134. At this time, the partition plate part 137 partitions the internal space of the housing 134 into a space where the sensor part 133 is arranged and a space where the sensor part 133 is not arranged. Thus, since the partition plate part 137 partitions the internal space of the housing 134, it is possible to further shield external heat energy from flowing into the sensor part 133 side.

  Since the partition plate portion 137 partitions the internal space of the housing 134, a portion near the mandrel 120 and a portion far from the mandrel 120 in the housing 134 can be spatially divided. Therefore, even if a portion near the mandrel 120 is heated, it is possible to reduce the transfer of hot air to a portion far from the mandrel 120. The internal space of the housing 134 that is remote from the mandrel 120 substantially functions as a heat blocking buffer.

  The partition plate portion 137 is formed with a passage hole portion 137a so that the light L emitted from the sensor portion 133 can pass therethrough. Since the passage hole portion 137a is formed in the partition plate portion 137, the light L emitted from the sensor portion 133 can be smoothly reached to the segment member 124 without being blocked by the partition plate portion 137.

  The exhaust port 138 is provided on the opposite side where the base 131 is disposed. As shown in FIG. 6 of the present embodiment, since the base 131 is provided on the lower side of the housing 134, the exhaust port 138 is provided on the upper side on the opposite side. The exhaust port 138 of the housing 134 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, the sensor unit 133 can be prevented from being deteriorated by the air heated inside the housing 134.

  A check valve (not shown) is provided inside the exhaust port 138 so as to open the exhaust port 138 when the internal pressure of the housing 134 becomes equal to or higher than a certain pressure.

  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 is formed larger than the outer diameter of the second housing 136. At this time, the partition plate portion 137 may be disposed between the first housing 135 and the second housing 136 to partition the internal space between the first housing 135 and the second housing 136. The exhaust port 138 is provided in the second housing 136.

  The first housing 135, together with the base 131, shields the space where the sensor unit 133 is provided from the outside, and the second housing 136 forms a heat blocking space on the upper end portion (reference to FIG. 6) side of the first housing 135. Therefore, the sensor unit 133 can block external heat energy from flowing in from the lower side by the base 131, and can block external heat energy from flowing in from the side by the first housing 135. The second housing 136 and / or the partition plate portion 137 can block external heat energy from flowing in from above.

  The second housing 136 has a passage hole portion 136a corresponding to the passage hole portion 137a of the partition plate portion 137. The passage hole portion 136 a of the second housing 136 and the passage hole portion 137 a of the partition plate portion 137 are formed on the traveling path of the light L emitted from the sensor portion 133. The sensor part 133 is protected from the outside by the first housing 135 and the second housing 136, and the light L emitted from the sensor part 133 passes through the two passage hole parts 136a and 137a and then reaches the segment member 124. The

  The cooling channel part 139 is disposed in the base 131 and the housing 134. The cooling channel portion 139 forms a flow path so that the cooling medium flows. As the cooling medium flows along the cooling channel part 139, the base 131 and the housing 134 are cooled. As the cooling medium, cooling water, cooling oil, or the like is applicable.

  The cooling channel part 139 is disposed in a spiral shape on the housing 134 and the base 131. Therefore, the thermal contact area between the cooling channel part 139 and the housing 134 and between the cooling channel part 139 and the base 131 can be increased, and the cooling efficiency of the housing 134 and the base 131 can be improved.

  The housing 134 is cooled by the cooling medium, and is cooled by discharging the air inside the housing 134 to the outside. Therefore, the housing 134 can be cooled by two cooling media.

  The cooling channel part 139 includes a base 131, specifically, a first cooling channel part 139 a disposed on the base plate 131 a and a second cooling channel part 139 b disposed on the housing 134. Since the first cooling channel part 139a is variously arranged in the base 131 such as a coil form, the base 131 provided with the sensor part 133 can be directly cooled by the cooling medium. Since the second cooling channel part 139b is arranged in a spiral shape around the housing 134 to cool the housing 134, the sensor part 133 arranged inside the housing 134 can be prevented from being heated. .

  The second cooling channel part 139 b is provided only in the first housing 135. Therefore, the internal space of the first housing 135 can be cooled by a fluid such as cooling water or cooling oil, and the internal space of the second housing 136 can be cooled by a gas such as air. Thus, since the first housing 135 and the second housing 136 are cooled by different cooling media, the cooling section can be divided by the cooling media.

  Of course, the second cooling channel part 139b may be provided in all of the first housing 135 and the second housing 136.

  The operation of the rolling coil winding device according to the present invention configured as described above will be described.

  FIG. 8 is a front view showing a state in which the rolling coil is wound around the mandrel in the rolling coil winding device according to the embodiment of the present invention, and FIG. 9 is a drawing of the rolling coil according to the embodiment of the present invention. It is sectional drawing which shows the state which the segment member of the mandrel in the taking device expanded outside.

  8 and 9, the strip is rolled by a rolling mill (not shown) to form a rolled coil C. The rolling coil C is transferred by a transfer roller (not shown) and flows into the coil inflow portion 111. The rolling coil C is guided to the mandrel 120 side by the pinch roller 114 at the coil inflow portion 111.

  The pressure frame 153 of the pressure unit 150 is disposed in the vicinity of the segment member 124 of the mandrel 120. At this time, the pressure roller 155 is disposed at a certain distance from the outer peripheral surface of the segment member 124. The pressure roller 155 and the segment member 124 can be changed according to the type and thickness of the rolled coil C wound around the mandrel 120.

  As the mandrel 120 rotates, the rolling coil C supplied from the pinch roller 114 is wound around the mandrel 120. The pressure roller 155 is in rolling contact with the rolling coil C when the rolling coil C is wound thereon. When the rolling coil C is wound about the mandrel 120 about 2 to 5 times, the rod 128a of the moving device 128 is drawn into the cylinder 128b. At this time, since the outer diameter of the segment member 124 increases as the mandrel body 121 moves with the segment member 124, the rolled coil C wound around the mandrel 120 is stretched with tension. Since the rolled coil C wound around the mandrel 120 is tight, the outer diameter of the rolled coil C becomes uniform, so that the rolled coil C is wound in close contact with the mandrel 120.

  As the mandrel 120 continuously rotates, the diameter of the rolled coil C wound around the mandrel 120 also gradually increases. At this time, the pressure piston 151 rotates around the hinge portion 151c so as to be far from the mandrel 120, and the pressure rod 151b is drawn into the pressure cylinder 151a. Accordingly, the pressure roller 155 becomes farther from the mandrel 120 as the diameter of the rolling coil C wound around the mandrel 120 increases.

  While the mandrel 120 is winding the rolled coil C, hot air from the rolled coil C is continuously transmitted to the mandrel 120, the pressurizing unit 150, and the distance measuring device 130. At this time, the distance measuring device 130 is cooled by the cooling medium as follows.

  The housing 134 and the base 131 are cooled by the cooling medium flowing through the cooling channel portion 139. The first cooling channel portion 139 a is disposed on the base 131 to cool the base 131, and the second cooling channel portion 139 b is provided on the housing 134 to cool the housing 134.

  The partition plate part 137 partitions the internal space of the housing 134 into a space in which the sensor part 133 is arranged and a space in which the sensor part 133 is not arranged (see FIG. 6). Since the partition plate portion 137 partitions the internal space of the housing 134, it shields external heat energy, particularly heat energy on the second housing 136 side, from flowing into the sensor portion 133 side through the second housing 136 and the partition plate portion 137. be able to. In addition, since the partition plate portion 137 partitions the internal space of the housing 134, a portion near the mandrel 120 and a portion far from the mandrel 120 in the housing 134 can be spatially divided. Therefore, even if a portion near the mandrel 120 is heated, it is possible to reduce the transfer of hot air to a portion far from the mandrel 120.

  The exhaust port 138 discharges air existing in the internal space of the housing 134 to the outside. Since the internal air of the housing 134 is exhausted to the outside by the exhaust port 138, it is possible to reduce the deterioration of the sensor unit 133 due to the air heated inside the housing 134.

  FIG. 10 is a configuration diagram showing a state in which a rolling coil is further wound around a mandrel in a rolling coil winding device according to an embodiment of the present invention, and FIG. 11 is 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 mandrel in the winding device for a contracted.

  Referring to FIGS. 10 and 11, when the winding process of the rolling coil C is completed, the lifting piston 176 of the coil transfer device 170 raises the lifting unit 174. The rolled-up coil 174 is supported by the raising / lowering part 174 rising. When the rod 128a of the moving device 128 is pulled out from the cylinder 128b, the inclined surface portion 122 of the mandrel body 121 moves while sliding with the contact surface portion 125 of the segment member 124. At this time, the segment member 124 moves toward the center portion of the mandrel body 121 as the inclined surface portion 122 moves toward the side where the width of the contact surface portion 125 increases. Accordingly, since the outer diameter of the segment member 124 is reduced, the wound rolled coil C can be easily separated from the mandrel 120.

  When the rolled coil transfer device 170 loaded with the rolled coil C is moved along the rail 117, the rolled coil C is separated from the mandrel 120 and then discharged to the outside of the rolled coil winding device. Is done.

  FIG. 12 is a cross-sectional view showing a deformed state of the mandrel segment member in the rolling coil winding device according to the embodiment of the present invention, and FIG. 13 shows the rolling coil winding according to the embodiment of the present invention. It is a front view which shows the state which a distance measuring device measures the distance of a segment member when the segment member of the mandrel in a taking device deform | transforms.

  Referring to FIGS. 12 and 13, after the rolled coil C wound up from the mandrel 120 is separated, the mandrel 120 is cooled by the cooling fluid while rotating. While the rolled coil C of about 600 ° C. is being wound around the mandrel 120, the mandrel 120 and the pressure unit 150 are heated.

  When the mandrel 120 is heated, the segment member 124 can be thermally deformed. At this time, the central portion of the segment member 124 has a thermal contact area narrower than that of both side portions of the segment member 124, so that the degree of thermal deformation is relatively large at the central portion of the segment member 124. Further, a centrifugal force acts on the segment member 124 while the mandrel 120 is rotating. 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 deformed so as to slightly bulge outward. As described above, the segment member 124 is deformed so that the outer diameter of the central portion is larger than that of the both side portions due to heat and centrifugal force.

  The sensor unit 133 measures the distance between the segment member 124 and the sensor unit 133 by irradiating the outer surface of the segment member 124 with light L. When the controller 160 determines that the outer diameter of the segment member 124 has increased due to the deformation of the segment member 124 due to heat and centrifugal force, the controller 160 drives the pressure piston 151 to move the pressure roller 155 and the segment. The distance from the outer surface of the member 124 is kept constant. Therefore, it is possible to prevent the segment member 124 from contacting the pressure roller 155 when the mandrel 120 rotates without the rolled coil C being wound, and the segment member 124 and the pressure roller 155 are damaged. Can be cut off.

  The present invention has been described with reference to the embodiments shown in the drawings. However, the present invention is merely illustrative, and various modifications may be made by those having ordinary skill in the art. It will be understood that other equivalent embodiments are possible. Therefore, the true technical protection scope of the present invention should be determined by the claims.
