Mandrel body 121 can be rotatably installed in winding body 110. Mandrel body 121 can have inclined surface part 122, and this inclined surface part 122 is formed at the outer surface of mandrel body 121, and this inclined surface part 122 circumferentially direction is arranged. Mandrel body 121 can include multiple inclined surface part 122 being formed at its outer surface. Now, multiple inclined surface parts 122 could be arranged to be formed along a line of the longitudinal direction (left and right directions in Fig. 2) of mandrel body 121. Fig. 3 shows a kind of structure, and in the structure shown here, inclined surface part 122 is arranged parallel in four routes of longitudinal direction (left and right directions in Fig. 2) of mandrel body 121. But, inclined surface part 122 quantity of the route formed can change into various value.
Section component 124 can have multiple inclining contact surfaces part 125 being formed within surface. Multiple contact surface portion divide a line of 125 longitudinal directions (left and right directions in Fig. 2) that could be arranged to be formed along section component 124. Multiple contact surface portion are divided 125 can with multiple inclined surface part 122 one_to_one corresponding of mandrel body 121. The a plurality of line one_to_one corresponding of multiple inclined surface parts 122 that multiple section components 124 can be formed with the longitudinal direction along mandrel body 121. When multiple inclined surface parts 122 are arranged in parallel to four lines of the longitudinal direction of mandrel body 121 time, it is possible to four section components 124 are installed.
Section component 124 can be linked to mandrel body 121 by link component 127. Link component 127 can make section component 124 move within predetermined distance range along the longitudinal direction of mandrel body 121. When mandrel body 121 relatively moves relative to section component 124 time, the inclined surface part 122 of mandrel body 121 can move while the contact surface portion sliding on section component 124 is divided on 125. Now, owing to section component 124 is away from or closer to the center of mandrel body 121, the overall diameter of section component 124 can expand or reduce.
Mobile device 128 can be connected to mandrel body 121. By the operation of mobile device 128, mandrel body 121 relatively can move relative to section component 124. Therefore, when mobile device 128 action time, the overall diameter of section component 124 can expand or reduce.

Along with liquid supply to cylinder 128b, bar 128a can advance from cylinder 128b, and along with liquid is discharged from cylinder 128b, bar 128a can be retracted in cylinder 128b.Along with bar 128a moves, mandrel body 121 can move in the left and right directions of Fig. 2.
Mandrel 120 can include multiple along its press portion 150 disposed circumferentially around. The rolling coiled material C being wound around around mandrel 120 can be pressurizeed by press portion 150. Press portion 150 can include pressurizing piston 151, increased pressure frame 153 and impression roller 155.
Pressurizing piston 151 may be mounted in winding body 110 and rotates along the circumference of mandrel 120 will pass through hinge portion 151c. Pressurizing piston 151 can include pressurized cylinder 151a and add pressure bar 151b. Along with liquid supply is to pressurized cylinder 151a, adding pressure bar 151b can advance from pressurized cylinder 151a, and along with liquid is discharged from pressurized cylinder 151a, adds pressure bar 151b and can be retracted in pressurized cylinder 151a.
What increased pressure frame 153 can engage to pressurizing piston 151 adds pressure bar 151b. Distance-measuring device 130 can be arranged in increased pressure frame 153. It is retracted in pressurized cylinder 151a along with adding pressure bar 151b or advances from pressurized cylinder 151a, it is possible to adjusting the interval between increased pressure frame 153 and the section component 124 of mandrel 120.
Impression roller 155 can be arranged at a surface of increased pressure frame 153 or be arranged at the surface towards mandrel 120 especially. The rolling coiled material C being wound around around mandrel 120 can be pressurizeed by impression roller 155. Therefore, rolling coiled material C can be wound around around mandrel 120 with such a state, and in this state, rolling coiled material C pressurizes against mandrel 120. Such as, in time rolling coiled material C and be wound around around mandrel 120, along with liquid supply is to pressurized cylinder 151a, adding pressure bar 151b can advance from pressurized cylinder 151a. Before impression roller 155 touches rolling coiled material C, adding pressure bar 151b can advance from pressurized cylinder 151a. Therefore, in time rolling coiled material C and be wound around around mandrel 120, impression roller 155 can rotate while rolling coiled material C at Structure deformation.
Distance-measuring device 130 may be mounted in press portion 150. Now, distance-measuring device 130 may be mounted in each in multiple press portion 150 or in only one press portion 150. Distance-measuring device 130 can be measured from measuring the target distance to distance-measuring device 130. Measure target and can include mandrel 120 or the rolling coiled material C being wound around around mandrel 120. Therefore, in time measuring target and be mandrel 120, distance-measuring device 130 can measure the distance from mandrel 120 to distance-measuring device 130; And be around when rolling coiled material C of mandrel 120 winding when measuring target, distance-measuring device 130 can measure the distance from rolling coiled material C to distance-measuring device 130.
Distance-measuring device 130 can be cooled down by cooling medium. Therefore, although distance-measuring device 130 is installed on off-chip axle 120 or the short distance of rolling coiled material C, but still it is possible to prevent distance-measuring device 130 by the heat damages from mandrel 120 or rolling coiled material C generation.
Controller 160 can adjust the interval between press portion 150 and mandrel 120 or press portion 150 and the interval rolled between coiled material C being wound around around mandrel 120 according to the distance measured by distance-measuring device 130. By distance-measuring device 130, it is possible to the distance between distance between air plug gauge 120 and press portion 150 or the rolling coiled material C and the press portion 150 that are wound around around mandrel 120 in real time.Based on measured value, it is possible to adjusted the interval between press portion 150 and mandrel 120 or press portion 150 and the interval rolled between coiled material C being wound around around mandrel 120 by controller 160.
Owing to the interval between press portion 150 and mandrel 120 or press portion 150 and the interval rolled between coiled material C around mandrel 120 winding obtain and regulate in real time, therefore it is possible to prevent before rolling coiled material C is wound around around mandrel 120, the damage that the impression roller 155 of press portion 150 causes because contacting with mandrel 120. After rolling coiled material C is wound around around mandrel 120, it is possible to suppressing the impression roller 155 excessive pressurization to rolling coiled material C of press portion 150, this allows to prevent that impression roller 155 or the damage of rolling coiled material C.
Controller 160 can suitably adjust the interval between mandrel 120 and press portion 150 according to the thickness of the rolling coiled material C being wound around around mandrel 120. In other words, controller 160 may determine that the distance (being measured by distance-measuring device 130) on the surface of distance rolling coiled material C and controls pressurizing piston 151 to adjust the interval between mandrel 120 and press portion 150. Therefore, along with the thickness of the rolling coiled material C being wound around around mandrel 120 increases, the impression roller 155 of press portion 150 can separate from mandrel 120. Therefore, although the thickness of rolling coiled material C there occurs change, but rolling coiled material C can be pressurizeed by impression roller 155 with constant plus-pressure. In other words, owing to can be measured the distance to rolling coiled material C (this rolling coiled material C is wound around around mandrel 120) in real time by distance-measuring device 130, therefore the position of impression roller 155 can be adjusted immediately in response to the thickness change of rolling coiled material C.
Track 177 can be arranged at the lower section of mandrel 120. On track 117, coiled material transporter 170 can be installed as and be moved by the winding rolling coiled material C of load thereon.
Coiled material transporter 170 can include framework 171, driving wheel 172, promotes/fall part 174, promote/fall piston 176 and roller 177, this driving wheel 172 is arranged at the both sides place of framework 171 and rotates along track 117, this lifting/fall part 174 is arranged in framework 171, this lifting/fall piston 176 promotes/falls part 174 for promoting or falling, and this roller 177 is arranged at the top place promoting/fall part 174 and supports winding rolling coiled material C.
In time being wound around rolling coiled material C and be loaded on roller 177, promoting/fall part 174 can decline by promoting/fall piston 176. Then, along with driving wheel 172 is driven, while coiled material transporter 170 is transferred into the outside of wind for rolling coiled material, rolling coiled material C can be transferred into outside.
Fig. 4 is the axonometric chart for rolling the distance-measuring device in the wind of coiled material according to embodiment of the present invention, Fig. 5 is the exploded perspective view for rolling the distance-measuring device in the wind of coiled material according to embodiment of the present invention, Fig. 6 is the cross-sectional view for rolling the distance-measuring device in the wind of coiled material according to embodiment of the present invention, Fig. 7 is the axonometric chart of pedestal, this pedestal define according to embodiment of the present invention for rolling the distance-measuring device in the wind of coiled material.
With reference to Fig. 4 to Fig. 7, distance-measuring device 130 can include pedestal 131, sensor unit 133, housing 134 and cooling duct part 139.
Pedestal 131 can be formed with the shape of polygonal panel or circular slab. Pedestal 131 can include base plate 131a, insulating element 131b and supporting member 131c.
Base plate 131a can engage to housing 134 so that from the inner space of outer protection housing 134. In other words, base plate 131a can close the inner space of the housing 134 of opening.
Insulating element 131b can engage to base plate 131a and be arranged on the inner space of housing 134. Insulating element 131b can include isolated material, and sensor unit 133 can be fixed on insulating element 131b. Intercepting accordingly, because the heat energy outside housing 134 is isolated component 131b and cannot flow into housing 134, therefore heat energy can be blocked and can not conduct to sensor unit 133. Accordingly it is possible to prevent sensor unit 133 causes damage or fault due to external heat.
Supporting member 131c can be erected on insulating element 131b. The surface that supporting member 131c can engage to sensor unit 133 is to support sensor unit 133. In other words, the lower surface (based on Fig. 5) of sensor unit 133 can be supported by insulating element 131b, and a side surface of sensor unit 133 can be supported by supporting member 131c. Therefore, although vibration can be transmitted by press portion 150 when rolling coiled material C is wound around around mandrel 120, but sensor unit 133 can not leave home position.
Sensor unit 133 may be mounted on pedestal 131 or is typically mounted on insulating element 131b, and emitting light in mandrel 120 or rolling coiled material C (this rolling coiled material C is wound around around mandrel 120), mandrel 120 or rolling coiled material C are for measuring target. Sensor unit 133 can include laser sensor, and laser is radiated on the section component 124 of mandrel 120 or in rolling coiled material C (this rolling coiled material C is wound around around mandrel 120) by this laser sensor. Sensor unit 133 can include various types of sensor, as long as sensor unit 133 can irradiate the light distance with the outer surface of measurement to mandrel 120 or the surface of rolling coiled material C (this rolling coiled material C is wound around) around mandrel 120.
Housing 134 can engage to pedestal 131. Now, the inner space of housing 134 can by pedestal 131 from exterior protection. Therefore, it can the invasion and attack from the moisture outside housing 134, heat energy and exogenous impurity of the protection setting sensor unit 133 in housing 134. Accordingly it is possible to prevent moisture outside housing 134, heat energy and exogenous impurity damage sensor unit 133.
Housing 134 may further include dividing plate 137 and air vent 138.
Dividing plate 137 can be arranged in the inner space of housing 134 to separate the inner space of housing 134. Now, the inner space of housing 134 can be divided into the space placing sensor unit 133 and the space not placing sensor 133 by dividing plate 137. Owing to the inner space of housing 134 is separated by dividing plate 137, external heat flow sensor unit 133 therefore can be stopped more reliably.
Owing to the inner space of housing 134 is separated by dividing plate 137, therefore the inner space of housing 134 can be divided into the part close to mandrel 120 and the part away from mandrel 120 by dividing plate 137. Therefore, although the part close to mandrel 120 is heated, but the heat being transferred to the part away from mandrel 120 can be reduced. Housing 134 can generally play heat away from the part of mandrel 120 and intercept the effect of relief area.
Dividing plate 137 can have through hole 137a, from light L traverse this through hole 137a that sensor unit 133 irradiates. Owing to dividing plate 137 has through hole 137a formed in which, the light L irradiated from sensor unit 133 will not be stopped by dividing plate 137, and can successfully be transferred to section component 124.
Air vent 138 can be installed on the opposite side of the side arranging pedestal 131. As shown in Figure 6, owing to pedestal 131 is installed on the bottom place of housing 134, therefore air vent 138 can be installed on opposite side or the top place of housing 134. The air vent 138 of housing 134 can will be present in the air venting in the inner space of housing 134 to outside. Owing to the inner air of housing 134 is discharged to outside by air vent 138, the air of heating in housing 134 therefore can be suppressed to make sensor unit 133 degenerate.
Air vent 138 can include check valve (not shown) installed therein, and when the internal pressure of housing 134 equals to or more than predetermined pressure time, this check valve is used for opening air vent 138.
Housing 134 can include the first housing 135 and the second housing 136, and this first housing 135 engages to pedestal 131, and this second housing 136 engages to the first housing 135. First housing 135 can have the overall diameter more than the second housing 136. Now, dividing plate 137 can be arranged between the first housing 135 and the second housing 136, and makes the inner space of the first housing 135 separate with the inner space of the second housing 136. Air vent 138 can be installed on the second housing 136.
First housing 135 can utilize pedestal 131 to have the space of sensor unit 133 (this sensor unit 133 is arranged on the first housing 135) from exterior protection, and the second housing 136 can form heat baffle space. Therefore, pedestal 131 can stop that external heat is transferred to sensor unit 133 from bottom, first housing 135 can stop that heat energy is transferred to sensor unit 133 from sidepiece, and the second housing 136 and/or dividing plate 137 can stop that external heat is transferred to sensor unit 133 from top.
Second housing 136 can have corresponding for the through hole 137a through hole 136a with dividing plate 137. The through hole 136a of the second housing 136 and through hole 137a of dividing plate 137 can be formed on the propagation path of the light L irradiated from sensor unit 133. Sensor unit 133 can by the first housing 136 and the second housing 136 from outer protection, and the light L irradiated from sensor unit 133 can pass two through hole 136a and 137a and arrive section component 124.

Hereafter, the operation according to the wind for rolling coiled material of embodiment of the present invention will be described as follows.
Fig. 8 shows the front view of a kind of state, and in a state, rolling coiled material is wound around around the mandrel being used for rolling in the wind of coiled material according to embodiment of the present invention; Fig. 9 shows the cross-sectional view of a kind of state, in a state, expands outwardly according to the section component being used for rolling the mandrel in the wind of coiled material of embodiment of the present invention.
With reference to Fig. 8 to Fig. 9, rolling mill (not shown) rolled strip can roll coiled material C to be formed. Rolling coiled material C can transmit along transfer roller (not shown), and introduces to coiled material introducing portion 111. Rolling coiled material C can be guided towards mandrel 120 by pulley tightener 114 in coiled material introducing portion 111.
The increased pressure frame 153 of press portion 150 can adjoin the section component 124 of mandrel 120 and arrange. Now, impression roller 155 can be arranged at predetermined intervals from the external peripheral surface of section component 124. Impression roller 155 and section component 124 can be changed according to the type of rolling coiled material C (this rolling coiled material C will be wound around around mandrel 120) or thickness.
Along with mandrel 120 rotates, can be wound around around mandrel 120 from the rolling coiled material C of pulley tightener 114 supply. Along with rolling coiled material C is wound around, impression roller 155 can Structure deformation extremely rolling coiled material C. In time rolling coiled material C and be wound around two circles to five circles around mandrel 120, the bar 128a of mobile device 128 can be retracted in cylinder 128b. Now, expanding owing to the overall diameter of section component 124 moves from section component 124 along with mandrel body 121, the rolling coiled material C being wound around thus around mandrel 120 can expand slightly. Rolling coiled material C owing to being wound around around mandrel 120 is tightened up, and therefore rolling coiled material C can have consistent overall diameter. Therefore, rolling coiled material C can be wound around with such a state, and in this state, rolling coiled material C is pressed against on mandrel 120.
Along with mandrel 120 rotates continuously, the diameter rolling coiled material C being wound around around mandrel 120 can little by little increase. Now, pressurizing piston 151 can rotate so that away from mandrel 120 around hinge portion 151c, adds pressure bar 151b and can be retracted in pressurized cylinder 151a. Therefore, along with the diameter of the rolling coiled material C being wound around around mandrel 120 increases, impression roller 155 may be located remotely from mandrel 120.
When mandrel 120 winding rolling coiled material C time, the heat of rolling coiled material C can be transferred to mandrel 120, press portion 150 and distance-measuring device 130 continuously.Now, distance-measuring device 130 can be cooled down by cooling medium.
Along with cooling medium is through cooling duct part 139, housing 134 and pedestal 131 can be cooled. First cooling duct part 139a can be arranged in pedestal 131 so that cooling base 131, and the second cooling duct part 139b may be mounted in housing 134 to cool down housing 134.
The inner space of housing 134 can be divided into the space placing sensor unit 133 and the space not placing sensor 133 (with reference to Fig. 6) by dividing plate 137. Owing to the inner space of housing 134 is separated by dividing plate 137, therefore can pass through the second housing 136 and dividing plate 137 and stop that the heat energy of external heat or the second housing 136 especially is transferred to sensor unit 133. Additionally, due to the inner space of housing 134 is separated by dividing plate 137, therefore inner space can be divided into the part close to mandrel 120 and the part away from mandrel 120 by dividing plate 137. Therefore, although the part close to mandrel 120 is heated, but the heat transmission to the part away from mandrel 120 can be reduced.
Air vent 138 can will be present in the air venting in the inner space of housing 134 to outside. Owing to the inner air of housing 134 is discharged to outside by air vent 138, the air of heating in housing 134 therefore can be suppressed to make sensor unit 133 degenerate.
Figure 10 shows the view of a kind of state, in a state, rolling coiled material is wound around further around the mandrel being used for rolling in the wind of coiled material according to embodiment of the present invention, Figure 11 shows the cross-sectional view of a kind of state, in a state, the section component of mandrel is retracting for rolling in the wind of coiled material according to embodiment of the present invention.
With reference to figures 10 to Figure 11, when the winding process being used for rolling coiled material C completes time, the lifting of coiled material transporter 170/fall piston 176 can promote promoting/fall part 174. Promote/fall part 174 and can be promoted to the rolling coiled material C supporting winding. Along with the bar 128a of mobile device 128 advances from cylinder 128b, the inclined surface part 122 of mandrel body 121 can move while the contact surface portion sliding on section component 124 is divided on 125. Now, along with inclined surface part 122 divides the width place of broadening of 125 to move towards contact surface portion, section component 124 can move towards the center of mandrel body 121. Thus owing to the overall diameter of section component 124 reduces, the rolling coiled material C of winding can easily separate with mandrel 120.
Along with coiled material transporter 170 (on this coiled material transporter 170, the rolling coiled material C being wound around in load) moves along track 117, rolling coiled material C can separate and be discarded to subsequently the outside of the wind for rolling coiled material with mandrel 120.
Figure 12 shows the cross-sectional view of a kind of state, in a state, the section component of mandrel according to embodiment of the present invention for rolling deformation in the wind of coiled material, Figure 13 shows the front view of a kind of state, in a state, when according to embodiment of the present invention for rolling the section deformation of member of the mandrel in the wind of coiled material time, the distance to section component measured by distance-measuring device.
Referring to figs 12 to Figure 13, after the rolling coiled material C being wound around around mandrel 120 separates, mandrel 120 can rotate and cooled down by cooling medium. When at the temperature of about 600 DEG C, rolling coiled material C is wound around around mandrel 120, mandrel 120 and press portion 150 are likely to be heated.
Along with mandrel 120 is heated, section component 124 is it may happen that thermal deformation. Now, owing to the core of section component 124 has less thermal contact area compared with the two side portions of section component 124, therefore the thermal deformation of the central part office of section component 124 is likely to relatively increase. Additionally, when mandrel 120 rotates, centrifugal force can apply to section component 124. Owing to the two side portions of section component 124 is engaged by link component 127, therefore the core of section component 124 can deform with protruding slightly above. Similarly, the core of section component 124 can be deformed into by heat compared with the two side portions of section component 124 have bigger overall diameter with centrifugal force.
Light L can be radiated on the outer surface of section component 124 by sensor unit 133, in order to measures the distance between section component 124 and sensor unit 133. When the overall diameter determining section component 124 deforms (being caused by heat and centrifugal force) along with section component 124 and expands time, controller 160 can drive pressurizing piston 151 constantly to keep the interval between the outer surface of impression roller 155 and section component 124. Therefore, time when mandrel 120 rotates on and do not roll coiled material C around its winding, controller 160 is possible to prevent contacting between section component 124 with impression roller 155, thus preventing section component 124 and the damage of impression roller 155.
Although providing some embodiments thus setting forth the present invention in conjunction with accompanying drawing, described embodiment is clearly to those skilled in the art and only provides by way of example, and can carry out various amendment and equivalencing without deviating from the spirit and scope of the present invention. The scope of the present invention is only defined by claims.
