Definitions

  • This invention relates to a coiler of the type in which a band plate is pressed against a mandrel by rollers.
  • the coiler is an installation for coiling a rolled band plate into the form of a coil to facilitate the transportation or shipment thereof to subsequent processes.
  • the known types of coilers are: the unit roller type in which the band plate is pressed against a mandrel by unit rollers and guided by circular guides, the belt horn type in which a belt is disposed so that the band plate is laid along the periphery of a mandrel, the chain horn type in which a roller chain is used instead of the belt, and the gripper type in which the advance of the leading end of the band plate is temporarily stopped when it reaches a mandrel and this leading end is gripped by a gripper provided on the periphery of the mandrel.
  • the unit roller type is further classified into two types: the roller independent movable type which has the function of individually opening/closing a plurality of unit rollers provided in one coiler and the roller interloclcing movable type in which a plurality of unit rollers are opened/closed by one actuator by means of a link mechanism or a slide mechanism.
  • Fig. 3 shows a conventional coiler, in which a rolled band plate 1 is conveyed on a roller table 2 and pulled in by a pair of pinch rollers 3a and 3b. Then, this band plate is guided between a gate 4 and an apron 5 and between an over guide 6a and a throat guide 6b, and is pressed against the periphery of a mandrel 8 by a plurality of unit rollers 7. After the leading end of the band .
  • the band plate 1 reaches the mandrel 8, the band plate 1 is bent so as to lie along the periphery of the mandrel 8 by the mandrel 8 and the unit rollers 7, rotating at circumferential speeds faster than the incoming speed of the band plate 1, and by circular guides 6c not rotating together with the mandrel 8; as a result, the band plate is progressively coiled around the mandrel 8 in piled form.
  • each unit roller 7 is controlled such that its circumferential speed becomes identical with the advancing speed of the band plate 1 after the band plate 1 reaches the position of the unit roller 7 and is pressed against the mandrel 8, the circumferential speed of the mandrel 8 is kept faster than the advancing speed of the band plate 1 until the band plate 1 fastens integrally around the mandrel 8. Then, the band plate 1 lying on the periphery of the mandrel 8, after coiled a few turns in piled form around the periphery of the mandrel 8 by being pressed against the mandrel 8 by means of the unit rollers 7, fastens integrally around the mandrel 8.
  • the unit rollers 7 press the band plate 1; hence, the unit rollers 7 are retracted to the outside of an allowable maximum coil 10 which the mandrel 8 can accommodate in coiling.
  • the band plate 1 To improve the capability of the band plate 1 to fasten around the mandrel 8, it is necessary to make a play or sag between the first turn of the band plate 1 and the periphery of the mandrel 8 as small as possible. Further, to improve the responsibility of the unit roller 7, the total weight of the unit roller 7 and its support frame must be decreased, the shift direction in opening/ closing of the unit roller 7 must be made to accord closely with the normal direction of the peripheral surface of the mandrel 8, the distance of shift of the unit roller 7 resulting from an increase in diameter of the coiled band plate 1 must be decreased, and so on.
  • the coiler shown in Fig. 7 is featured in that a rotary bearing portion of the unit roller 7 is integral with the circular guide 6c, these components are secured to a main frame 9a which is in turn pivotably supported via a frame bearing 16 by a coiler housing 18, and these components are caused to open/close by means of a hydraulic cylinder 13 supported via a trunnion 14 by the coiler housing 18; hence, this coiler is the most popular one of the roller independent movable type.
  • the coiler shown in Fig. 8 is featured in that the unit roller 7 is rigidly supported by a roller frame 9b of small mass, and a buffer spring 15 is interposed between the main frame 9a and the roller frame 9b.
  • a buffer spring 15 is interposed between the main frame 9a and the roller frame 9b.
  • the coiler shown in Fig. 9 is featured in that an auxiliary circular guide 17 is secured to the roller frame 9b, and the respective tie-in portions of the auxiliary circular guide 17 and the circular guide 6c, which interfere with each other when the auxiliary circular guide 17 shifts relatively with respect to the circular guide 6c, are shaped in the form of comb teeth to prevent interference; hence, this coiler can partly ease the inconvenience of the coiler shown in Fig. 8.
  • the coiler shown in Fig. 10 is improved in the responsibility of the unit roller 7, because the support and shift motion of the unit roller 7 are achieved independent of the circular guide 6c.
  • the coiler shown in Fig. 11 is featured in that instead of the spring 15 used in the coiler of Fig. 8 or in addition thereto, a hydraulic cylinder 13 is assembled in, so that the position of the unit roller 7 can be controlled by the hydraulic cylinder 13 such that the unit roller 7 runs on the stepped portion of the coiled/piled band plate 1 corresponding to the leading end thereof without any shock.
  • the coiler shown in Fig. 12 is featured in that the main frame 9a is shifted by a link mechanism composed of two arms 11.
  • the frame bearing 16 serving as the center of rotation for the unit roller 7 or the circular guide 6c when they are to be shifted is located outside the allowable maximum coil 10, and even in a type like that shown in Fig. 9 in which the auxiliary circular guide 17 is provided so as to pivot inside the allowable maximum coil 10, the frame bearing 16 serving as the center of pivot of the circular guide 6c itself is located outside the allowable maximum coil 10. If desired to improve the responsibility of the unit roller 7 in the coiler shown in Fig. 4, the angle ⁇ between the shift direction of the unit roller 7 and the line connecting the axial center of the unit roller 7 with the axial center of the mandrel 8 must be made to approach zero.
  • the unit roller 7 runs on the stepped/raised portion of the coiled band plate 1 whose height corresponds to the thickness t thereof, the distance of shift becomes small, or the shift distance of the unit roller 7 when it retracts becomes small in case the position of- the unit roller 7 is subjected to control; accordingly, the responsibility of the unit roller 7 will be improved.
  • the rotation center 16 of the frame had to be located outside the outer diameter of the maximum coil 10 without exception. Further, ( in order to avoide interference when the maximum coil is reached ), the frame bearing 16 had to be located at a position where it cannot interfere with an incoming line 19 ( a tangent line with respect to both the bottom pinch roller 3b and the outer diameter of the maximum coil ) of the band plate when the maximum coil is reached as shown in Fig. 3.
  • the unit roller 7 had to be located close to the throat guide 6b.
  • the frame bearing 16 could not be displaced leftward in Fig. 4 for the foregoing reasons; as a result, the angle ⁇ could not be made small.
  • a coiler has a plurality of frame units, each frame unit comprising a first frame whose point portion faces opposite to the periphery of a mandrel for coiling a band plate and whose base end portion is rotatably pivoted to a shaft parallel to the axial line of the mandrel, a first drive unit for moving the first frame, a second frame rotatably pivoted in the point portion of the first frame to a shaft parallel to the axial line of the mandrel, a second drive unit coupled to the second frame and the first frame for moving the second frame, a pressing roller rotatably supported by the second frame for assisting fastening of the band. plate around the mandrel, and a circular guide provided on the second frame so as to face opposite to the mandrel.
  • the second frame rotatably supporting the pressing roller is pivoted to the point portion of the first frame and each of these two frames is provided with a driving cylinder; therefore, the location of the point of pivot of the second frame can be freely selected, so that both the angle ⁇ shown in Fig. 4 and the angle a shown in Fig. 6 can be made small.
  • the frame member for supporting the unit roller is divided into two: the second frame for rotatably supporting the pressing roller and the first frame for pivotably supporting the second frame; therefore, the limitations in arrangement of the conventional coilers are removed, hence, the capability of the band plate to fasten around the mandrel and the responsibility of the pressing roller are remarkably improved.
  • a first frame 9d is provided with a frame bearing 16 serving as the center of rotation of a compact, second frame 9e which integrally supports a unit roller ( a pressing roller ) 7 and a circular guide 6c, and with a cylinder 13c for causing the pivotal motion of the second frame.
  • the first frame 9d is pivoted by a cylinder 13d, which is supported by a trunnion 14, about a frame bearing 160 located outside an allowable maximum coil 10 of a band plate 1.
  • the first frame 9d and the second frame 9e can independently perform open/close motion.
  • the first frame 9d and the second frame 9e can move or shift in opposite directions independently. As shown in Figs. 1 and 2, when the first frame 9d is in the closed state, the frame bearing 16 serving as the center of rotation of the second frame 9e is located inside the allowable maximum coil 10, and it can be located on the left-hand side enough.
  • the frame bearing 16 of the second frame 9e supporting both the unit roller 7 and the circular guide 6c is located inside the allowable maximum coil 10 so that it is located close to the mandrel 8 with decreasing its radius of rotation, and as shown in Figs. 1 and 2, by locating the frame bearing 16 on the left-hand side enough, the angle ⁇ shown in Fig. 4 and the angle ⁇ shown in Fig. 6 can be made small; therefore, all the problems of the conventional coilers described with reference to Figs. 4 through 6 are solved.
