Definitions

  • the object of the invention is a device for coiling a metal strip into a coil.
  • coils contain considerably lengthy metal strip and are used for mass production at industrial plants.
  • rewinding devices are used, so-called rewinders, in which the strip is rewound from a larger coil to smaller coils.
  • US2212243A discloses a strip coffer for rolling mills comprising a mandrel, rollers adjacent thereto adapted to urge a strip progressively thereabout in forming a coil thereon, one of said rollers having a peripheral groove, means for supporting the rollers, and a finger carried by and extending from said means, into said groove and partially about the roller in the direction of its operative rotation and thence bridging the gap between said roller and an adjacent roller to thereby deflect the leading end of the strip away from said gap and toward the mandrel.
  • the object of the invention is a device for coiling a metal strip into a coil, comprising: a cylindrical chamber for coiling the metal strip; entry rollers located in front of the chamber for feeding the metal strip into the chamber; wherein a side wall of the chamber is formed by a plurality of rotating rollers arranged around a circumference of the chamber.
  • Two gripping mechanisms are located inside the chamber at the sides of the chamber, wherein the gripping mechanisms comprise rotatable grippers.
  • a number of the rotating rollers is mounted on a swivel arm.
  • the device is configured to operate at:
  • the grippers may comprise a locking element that is movable between a locking position that holds the metal strip in the gripper and an open position.
  • the grippers can be mounted on rotating axles that are slidably mounted within a body.
  • the rotating rollers can be longitudinal and are arranged in parallel to each other and in parallel to the axis of the chamber.
  • the device may further comprise a collecting platform for collecting the coil moved out from the chamber.
  • the rotating rollers can be connected to each other by a drive chain and are driven by a gear motor.
  • the device may further comprise a profiling mechanism with an actuator connected to a pressure roller for imparting an initial bending radius to the metal strip.
  • the device may further comprise a shaft for mounting a reel of foil to wrap the coil and feed rollers for feeding the foil from the reel.
  • the device may further comprise a cutter for cutting the foil, wherein the cutter is mounted on a toothed belt and is controlled by a gear motor.
  • Fig. 1A is a perspective view of the device for coiling a metal strip in a closed position, and Fig. 1B in an open position.
  • Fig. 2 is a cross-sectional view of the device.
  • the device comprises a cylindrical chamber 20 for coiling the metal strip and entry rollers 30, located in front of the chamber 20, for feeding the metal strip 1 into the chamber 20.
  • the device comprises a frame 10 on which the chamber 20 and the entry rollers 30 are mounted.
  • the side wall of the chamber 20 constitutes of a plurality of rotating rollers 21 distributed around the circumference of the chamber 20.
  • the rotating rollers 21 are longitudinal and are arranged in parallel to each other and in parallel to the axis of the chamber 20.
  • the device may comprise 20 rotating rollers 21 with a diameter of 70mm.
  • the device comprises two gripping mechanisms 40 located inside the chamber 20 on its both sides, wherein the gripping mechanisms 40 comprise rotatable and extendable grippers 41, wherein part of the rotating rollers 21 is mounted on a swivel arm 22.
  • the device is adapted to operate: in a loading configuration wherein the grippers 41 grip the front edge of the metal strip 1, in a coiling configuration wherein the swivel arm 22 is closed and the grippers 41 rotate around an axis together with the gripped metal strip 1, while guiding the edge of the metal strip 1 along the circumference of the chamber 20 as the metal strip is being coiled, and in an unloading configuration where the swivel arm 22 is open (as in Fig. 1B ) and the grippers 41 are extended beyond the formed coil, allowing the coil to be removed from the chamber 20.
  • the swivel arm 22 is controlled by an actuator 23.
  • a first embodiment Figs.
  • the retracting of the actuator 23 causes the arm 22 to rise and the chamber 20 to open, allowing the removal of the coil from the chamber 20.
  • the actuator 23 is mounted so that extending thereof causes the arm 22 to rise and the chamber 20 to open.
  • the raised arm 22 forms an opening in the chamber 20 with a height equal to its diameter.
  • the sheet As the sheet is coiled, its surface contacts at least some of the rotating rollers 21 which are driven and guide the metal strip to form it into a coil.
  • the rotating rollers 21 are connected by a chain to each other and to a gear motor that drives them.
  • the entry rollers 30 have the same linear speed as the rotating rollers 21 of the chamber 20.
  • the device comprises a profiling mechanism 60 that is in the form of an actuator 61, connected to a pressure roller 62, that, after gripping the metal strip by the grippers 41, presses the pressure roller 62 against the metal strip, between the entry rollers 30 and the grippers 41, in order to give it an initial bending radius.
  • the pressure roller 62 is in a position remote from the surface of the metal.
  • the device comprises a shaft for mounting a reel of foil 70, wherein the formed coil is wrapped by the foil in order to pack it, and preferably comprises feed rollers 71 for feeding the foil from the reel.
  • the foil is entered between the metal strip being coiled by activating the rollers 71 that feed the foil.
  • the device comprises a cutter 72 for cutting the foil, that is mounted on a toothed belt and is controlled by a gear motor that moves it in a direction transverse to the foil feed in order to cut a section of foil after wrapping the coil.
  • Fig. 4 is a perspective view of the gripper mechanism.
  • the gripper 41 is mounted on a rotating axle 43 which is slidably mounted in a body 46.
  • the rotating axle 43 of one of the rotatable grippers is connected to a drive motor by means of a belt transmission, while the drive to the rotating axle of the gripper 41 located on the other side of the device is transmitted by means of a drive shaft 48 ( Fig. 1 ).
  • Each gripper 41 has a locking element 42 that is movable between a position ( Fig. 6 ) locking the metal strip 1 in the gripper 41 and an open position ( Fig. 5 ) in which the metal strip can be freely slid in and out of the gripper 41.
  • the position of the locking element 42 is changed by means of an actuator 44.
  • the axle 43 is constructed to allow delivery of compressed air for controlling the actuator 44.
  • Fig. 7 shows the gripping mechanism with the gripper 41 in a working position.
  • Fig. 8 shows the gripping mechanism with the gripper 41 in a position extended from the coiling chamber 20.
  • the gripping mechanism 40 comprises an extendable element, preferably an actuator 45 that controls the extension of the axle 43 on which the gripper 41 is mounted.
  • the gripper 41 In the working position, the gripper 41 is located inside the chamber 20, in particular so as to grip the edge of the metal strip 1 fed by the entry rollers 30, and the actuator 45 controlling the extension of the gripper 41 is in the retracted position.
  • the gripper 41 is located outside the formed coil, in a particular case it is located outside the chamber 20, thus allowing the removal of the coil in a direction transverse to the axis of the coil.
  • the coil is rolled out by means of a shaft 26, controlled by actuators 25, onto a collecting platform 50 from which it is then collected. Thereby, irrespective of whether the coil has already been collected or whether it is still on the collecting platform 50, the device returns to the loading configuration and is ready for further operation. Due to the fact that the coil is removed from the chamber 20 in the direction transverse to the coil axis, i.e. also in the direction transverse to the axis of the chamber 20, it is not necessary to collect it immediately (e.g.
  • the device does not require the use of complicated elements for pushing the coil along the axis of the chamber, and only optionally comprises a short-stroke element in order to push the coil in the direction transverse to its axis.
  • the collecting platform 50 may be adapted to receive more than one coil.
