In addition, the terms described below are defined in consideration of the functions of the present invention, which may vary depending on the intention or custom of the user, the operator. Therefore, definitions of these terms should be made based on the contents throughout this specification.

FIG. 1 is a side view showing a strip winding apparatus according to an embodiment of the present invention, and FIG. 2 is a block diagram showing a strip winding apparatus according to an embodiment of the present invention.

Referring to Figs. 1 and 2, the rolled material is heated in a heating furnace (not shown) and then rolled in a rolling mill (not shown). As the rolled material is rolled in the rolling mill, a strip of strip 10 is produced. The strip 10 is cooled to the temperature required for winding through the cooling transfer table 20. The strip 10 past the cooling transfer table 20 is conveyed to the pinch roller portion 30.

The pinch roller portion 30 is rotated while being in rolling contact with both side surfaces of the strip 10. The pinch roller portion 30 includes an upper pinch roller 31 and a lower pinch roller 32 that are in contact with both side surfaces of the strip 10. The pinch roller unit 30 can keep the feeding speed of the strip 10 constant.

The strip 10 having passed through the pinch roller portion 30 is wound around the strip winding device 100. The strip winding device 100 includes a mandrel 130 and a pressing device 110.

The mandrel 130 is installed to be rotated by the mandrel driving unit 131. The mandrel 130 is wound with a strip 10. The mandrel 130 will be described in detail below.

A plurality of pressurizing devices 110 are installed around the mandrel 130 to press the strip 10 to be wound. The pressurizing device 110 includes a pressurizing piston 111, a pressurizing frame 115, and a pressurizing roller 117.

The pressure piston (111) is rotatably installed around the mandrel (130) by a hinge portion. The pressure piston 111 includes a pressurizing cylinder 112 and a pressurizing rod 113. As the fluid is supplied to the pressurizing cylinder 112, the pressurizing rod 113 is drawn out of the pressurizing cylinder 112 and the pressurizing rod 113 is moved to the inside of the pressurizing cylinder 112 as the fluid is discharged from the pressurizing cylinder 112 Lt; / RTI >

The pressurizing frame 115 is engaged with the pressurizing rod 113 of the pressurizing piston 111. The distance between the pressing frame 115 and the segment member 136 of the mandrel 130 is adjusted as the pressing rod 113 is pulled in or drawn out from the pressing cylinder 112. [

The pressure roller 117 is installed in the pressing frame 115. The pressure roller 117 presses the strip 10 to be wound and winds the script in a close contact state. The pressure roller 117 is rotated in rolling contact with the strip 10 when the strip 10 is wound.

A velocity measuring unit 101 is provided to measure the feeding speed of the strip 10. The velocity measuring unit 101 is disposed on the inlet side and the outlet side of the strip 10 of the pinch roller unit 30. [ The speed measuring unit 101 measures the feed speed of the strip 10 by irradiating the strip 10 with light. As the velocity measuring unit 101, various types can be applied as long as the velocity of the strip 10 can be measured.

The thickness measuring section 103 is provided so that the thickness (T: see FIG. 8) of the strip 10 can be measured. The thickness measuring unit 103 is provided on the pinch roller unit 30. [ The interval between the upper pinch roller 31 and the lower pinch roller 32 is measured when the strip 10 passes between the upper pinch roller 31 and the lower pinch roller 32. [ The distance between the upper pinch roller 31 and the lower pinch roller 32 is equal to the thickness T of the strip 10 because the upper pinch roller 31 and the lower pitch roller are in rolling contact with the opposite sides of the strip 10 .

The velocity measuring unit 101 and the thickness measuring unit 103 are connected to the controller 105 by wire or wirelessly. The control unit 105 is connected to the mandrel driving unit 131, the moving device 132, and the step varying device 140 in a wired and wireless manner.

The control unit 105 adjusts the rotation speed of the mandrel body 134 according to the speed of the strip 10 measured by the speed measuring unit 101. The rotation speed of the mandrel body 134 is adjusted in accordance with the speed of the strip 10 so that the strip 10 can be prevented from being loosely wound on the mandrel 130. [

5) so as to vary the height (H: see FIG. 8) according to the thickness T of the strip 10 measured by the thickness measuring unit 103, Adjusts the eccentric device (140). The height of the step portion 137 varies in accordance with the thickness T of the strip 10 so that the height of the outer side of the segment member 136 and the height of the tip portion 11 of the strip 10 The same can be made. When the thickness T of the strip 10 is thin, the height H of the stepped portion 137 is relatively lowered so that the leading end portion 11 of the strip 10 is spaced apart from the step portion 137 10 can be prevented from being loosely wound. When the thickness T of the strip 10 is relatively large, the height H of the stepped portion 137 is relatively increased so that the end mark 11 is formed by the end portion 11 of the strip 10, Can be prevented from being formed. Here, the end mark indicates that when the strip 10 is wound with the leading end 11 of the strip 10 protruding from the outer surface of the segment member 136, the strip 10 is wound around the leading end 11 of the strip 10 Quot; as used herein means a portion which is deformed to be protruded as it is superimposed.

FIG. 3 is a cross-sectional view illustrating a combined structure of a mandrel body and a segment member in a strip winding apparatus according to an embodiment of the present invention, and FIG. 4 is a cross-sectional view of a strip winding apparatus according to an embodiment of the present invention. FIG. 5 is a cross-sectional view illustrating a joint structure of a segment member and a step varying device in a mandrel body in a strip winding device according to an embodiment of the present invention. Referring to FIG.

3 to 5, a strip winding apparatus according to an embodiment of the present invention includes a mandrel 130 and a pressurizing device 110. The mandrel 130 includes a mandrel body 134, a plurality of segment members 136, and a step varying device 140.

The outer surface of the mandrel body 134 has a plurality of inclined surface portions 134a. The inclined surface portion 134a is arranged to form a row along the longitudinal direction of the mandrel body 134. [ 5 shows the structure in which the inclined surface portions 134a are arranged in four rows in parallel with the longitudinal direction of the mandrel body 134, the number of columns of the inclined surface portion 134a can be variously changed.

A plurality of segment members 136 are disposed to surround an outer portion of the mandrel body 134. The contact surface portion 136a is formed on the inner side surface of the segment member 136 so as to contact the inclined surface portion 134a of the mandrel body 134. [ The contact surface portion 136a is formed to be inclined. The contact surface portion 136a is formed to form a heat along the longitudinal direction of the segment member 136. [ The contact surface portion 136a of the segment member 136 is in one-to-one correspondence with the inclined surface portion 134a of the mandrel body 134. [ When the inclined surface portions 134a are arranged in four rows in parallel with the longitudinal direction of the mandrel body 134, three segment members 136 are provided. And the step difference variable device 140 is provided on the other inclined face portion 134a.

The link member 138 links the segment member 136 and the mandrel body 134. The link member 138 allows the segment member 136 to move in a range of distances along the length direction of the mandrel body 134. The inclined surface portion 134a of the mandrel body 134 is moved while sliding on the contact surface portion 136a of the segment member 136 when the mandrel body 134 is moved relative to the segment member 136. [ At this time, since the segment member 136 is moved away from or closer to the center of the mandrel body 134, the outer diameter of the segment member 136 is enlarged or reduced.

The mobile device 132 is connected to one side of the mandrel body 134. The moving device 132 enlarges and reduces the outer diameter of the segment member 136 as it moves the mandrel body 134 relative to the segment member 136. The moving device 132 may be a hydraulic device that moves the mandrel body 134 by hydraulic pressure.

The step varying device 140 is rotatably mounted on the outside of the mandrel body 134. The step varying device 140 forms a step portion 137 with the segment member 136 so that the leading end portion 11 of the strip 10 is accommodated. For example, when the step varying device 140 is rotated from the outer surface of the segment member 136 to the mandrel body 134 side, the segment member 136 is projected from the step varying device 140, 137 are formed. The distal end portion 11 of the strip 10 flows into the stepped portion 137. The height H of the stepped portion 137 is adjusted so that the distal end portion 11 of the strip 10 and the outer surface of the segment member 136 can have substantially the same height. Therefore, it is possible to prevent the distal end portion 11 of the strip 10 from being spaced apart from the step portion 137, thereby preventing the strip 10 from being wrapped. It is also possible to prevent the distal end portion 11 of the strip 10 from protruding from the outer surface of the segment member 136 to prevent the end mark from being formed on the strip 10.

The step difference variable device 140 includes a step difference variable member 141 and a rotation drive part 143. [

The stepped deformable member 141 is rotatably installed on the segment member 136 by the hinge portion 142 and forms a step portion 137 together with the outer surface of the segment member 136. As the step difference variable member 141 is rotated toward the mandrel body 134 or the opposite side thereof, a difference in height from the outer surface of the segment member is generated.

The outer side surface of the stepped portion deformable member 141 is formed with the same curvature as that of the outer surface of the segment member 136. [ Therefore, since the outer surface of the step difference varying member 141 and the outer surface of the segment member 136 are connected to each other and formed into a cylindrical shape, the strip 10 can be wound in the form of a circular coil.

The rotation drive portion 143 is disposed between the step portion variable member 141 and the inclined surface portion 134a of the mandrel body 134. [ The rotation drive section 143 rotates the step variable member 141. The position of the stepped portion deformable member 141 can be adjusted as the rotary drive portion 143 rotates the stepped portion deformable member 141. [

The rotation drive section 143 includes a piston section 144 coupled to the step variable section 141 and a contact member 145 connected to the piston section 144 and in contact with the slope section 134a of the mandrel body 134 ). The piston portion 145 includes a cylinder 144a accommodated in the fluid and a rod 144b movably coupled to the cylinder 144a. When the fluid is supplied to the cylinder 144a, the rod 144b is drawn out of the cylinder 144a. When the fluid is discharged from the cylinder 144a, the rod 144b is drawn into the cylinder 144a.

The contact member 145 is formed so as to be inclined so as to be in surface contact with the inclined surface portion 134a of the mandrel body 134. [ Therefore, since the contact member 145 can be stably supported on the inclined surface portion 134a of the mandrel body 134, it is possible to suppress the fluctuation or the positional change of the step portion deformable member 141 when the strip 10 is wound can do.

The control method of the strip winding apparatus according to the embodiment of the present invention will be described.

FIG. 9 is a cross- FIG. 3 is a cross-sectional view showing a state in which the strip is wound about one revolution in a state where the leading end of the strip is seated in the step portion in the apparatus. 10 is a flowchart showing a control method of a strip winding apparatus according to an embodiment of the present invention.

6 to 10, the rolled strip 10 is conveyed to the pinch roller portion 30 side (S11). At this time, the strip 10 is rolled to a constant thickness T.

The speed measuring unit 101 measures the feeding speed of the strip 10 and transmits it to the control unit 105 (S12). At this time, the speed measuring unit 101 measures the feeding speed of the strip 10 on the inlet side and the outlet side of the pinch roller unit 30. The velocity measuring unit 101 transmits a signal relating to the feeding speed of the strip 10 to the control unit 105. The control unit 105 can select the speed of the strip 10 on the discharge side of the strip 10 when the speed measured by the speed measuring unit 101 on the discharge side and the discharge speed on the discharge side are different.

The thickness measurement unit 103 measures the distance between the upper pinch roller 31 and the lower pinch roller 32 and transmits the measured distance to the control unit 105 (S13). The control unit 105 determines that the value of the interval between the upper pinch roller 31 and the lower pinch roller 32 is the thickness T of the strip 10.

The control unit 105 controls the rotation driving unit 143 of the step varying device 140 so that the height H of the step portion 137 becomes equal to the thickness T of the strip 10, 141). At this time, the height of the rotation driving part 143 is adjusted as the fluid flows into and out of the rotation driving part 143, and the height of the stepped part 141 is determined according to the height of the rotation driving part 143 (S14) .

The control unit 105 rotates the mandrel 130 according to the speed of the strip 10 (S15). At this time, the mandrel 130 can be rotated at a speed at which the strip 10 can be pulled and wound. The strip 10 can be prevented from being loosely wound on the mandrel 130 because the strip 10 is pulled and wound.

The leading end 11 of the strip 10 is drawn into the stepped portion 137 (see Fig. 8). At this time, the thickness T of the front end portion 11 of the strip 10 becomes the same as the height H of the step portion 137. When the mandrel 130 is rotated, the strip 10 is wound while being in contact with the outer surface of the segment member 136 and the step-variable member 141. The end surface 11 of the strip 10 and the outer surface of the segment member 136 form substantially the same surface when the strip 10 is wound on the mandrel 130 by one turn so that the end mark is formed on the strip 10 (See Fig. 9).

The distal end 11 of the strip 10 is restrained by the outer surface of the segment member 136 and the step portion 137 and the lower surface of the strip 10 so that when the strip 10 is wound, It is possible to prevent the distal end portion 11 of the cap member 11 from being released. Therefore, it is possible to prevent the occurrence of a failure in winding when the strip 10 is wound.

If the strip 10 is wound on the mandrel 130 about three to five turns, the control unit 105 controls the moving device 132. At this time, the moving device 132 moves the mandrel body 134 such that the segment members 136 extend outwardly. Thus, since the strip 10 is slightly stretched and brought into close contact with the mandrel 130, the strip 10 can be wound up tightly.

When the strip 10 is fully wound on the mandrel 130, the moving device 132 moves the mandrel body 134 to cause the segment member 136 to move to the side of the mandrel body 134. Accordingly, as the outer diameter of the mandrel 130 is reduced, the mandrel 130 can be easily removed from the wound strip 10.

Since the step height variable device 140 adjusts the height H of the step portion 137 as described above, the height H of the step portion 137 can be varied in accordance with the thickness T of the strip 10 . Since the stepped portion 137 is adjusted to the same height H as that of the front end portion 11 of the strip 10, the strip 10 having a different thickness T can be wound using the same strip winding device.

The step difference variable device 140 adjusts the height H of the step portion 137 to the thickness T of the strip 10 so that the tip portion 11 of the strip 10 is wound when the strip 10 is wound, Can be prevented from being lifted or protruded from the outer surface of the stepped portion deformable member 141. Therefore, it is possible to suppress the occurrence of the winding failure of the strip (10). It is also noted that the end mark is generated in the strip 10 wound by the leading end 11 of the strip 10 because the stepped portion 137 is adjusted to be substantially similar to or the same as the thickness T of the strip 10 .

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. I will understand.

Accordingly, the true scope of protection of the present invention should be defined by the claims.
