Definitions

  • This invention relates to an apparatus for winding strip metal, and in particular one in which the strip is guided onto a mandrel or the like by two or more wrapper rolls.
  • wrapper rolls it is well known to use wrapper rolls to guide metal strip round a mandrel while the first few turns are coiled. Once the coil is established the wrapper rolls are withdrawn and the mandrel expanded slightly to grip the coil. A problem arises during those first turns when the leading edge of the strip passes under the wrapper rolls and the strip is damaged by the rolls hammering the strip. The hammering occurs even when the leading edge is overlaid by the coiled strip because the overlying strip is deformed into a step adjacent the leading edge. Thus, damage can be caused over the whole period of the wrapper roll engagement and therefore be costly.
  • one aspect of the invention provides a coiler for metal strip which has a coiler mandrel, at least two wrapper rolls spaced about the mandrel for guiding the initial wraps of a coil about the mandrel, and actuating means for each of the wrapper rolls for urging the respective roll into engagement with the strip and for displacing that roll outwardly; and which includes, for each wrapper roll, sensing means associated with that wrapper roll and giving a sensor signal on the passage of the leading end of a strip past a given location, and means controlled by the sensor signal for operating immediately the actuating means of a wrapper roll in advance of said given location to displace that wrapper roll away from the mandrel.
  • leading edge should be considered to cover not only that edge alone but also that edge as ovelayed during coiling process.
  • Another aspect of the invention provides a method of coiling metal strip on a coiler which has a coiler mandrel, at least two wrapper rolls spaced about the mandrel for guiding the initial wraps of a coil about the mandrel, and actuating means for each of t'e wapper cells for urging the respective roll into engagement with the strip and for displacing that roll outwardly, the method comprising:
  • an apparatus for winding metal strip 10 includes a mandrel 1 for receiving the strip 10 and wrapper rolls 2, 3 and 4 for guiding the strip about the mandrel.
  • Each wrapper roll has a respective double-acting hydraulic ram 5, 6 or 7 which, in use, presses the associated wrapper roll 2, 3 or 4 the strip 10 into the mandrel 1 to coil the strip.
  • Guide plates 9 are provided about the mandrel, to assist in the guidance of the strip.
  • a set of pinch rolls 8 is arranged to feed the strip 10 to the mandrel.
  • each of the hydraulic rams 5, 6 and 7 has a respective sensor 11, 12 or 13 arranged to sense the hydraulic pressure in that ram, and in particular to sense any rise in that pressure.
  • the sensors 11, 12 and 13 are each connected with a control unit 5a, 6a, 7a, of an adjacent ram; in particular each sensor 11, 12 and 13 is connected with the control unit of the last ram in the advance direction of strip travel next to the roll with that particular sensor, or in other words, adjacent the ram in the opposite direction to the mandrel rotation (strip travel) i.e. the sensor at 11 is connected with the control unit 7a, the sensor 12 with control unit 5a, arid the sensor at 13 with the ram control unit 6a.
  • the wrapper rolls at 2 and 3 are displaced from the mandrel an amount slightly less than the thickness of the strip to be coiled, and the wrapper roll at 4 is left in contact or thereabouts with the mandrel.
  • the strip 10 is fed to the mandrel 1 from pinch rolls 8 and engages the wrapper roll 2, urging that roll outwards.
  • the strip is held between the wrapper roll at 2 and the mandrel 1 and the sensor 11 senses the increase in pressure in the hydraulic ram 5.
  • the sensor provides a signal to the control unit 7a so that the ram 7 can displace the wrapper roll 4 outwards by an amount slightly less than the strip thickness.
  • the sensor 12 provides a signal to the control unit 5a so that the ram 5 displaces the wrapper roll 2 outwards.
  • the sensor 13 signals to the control unit 6a so that the ram 6 displaces the wrapper roll 3 outwards.
  • pressure sensor may be used to sense the outward displacement of the wrapper rolls
  • accelerometers could be mounted on the roll carrying frame to sense the outward acceleration of the wrapper rolls when engaged by the leading edge or step in the strip.
  • each of the wrapper rolls 2, 3 and 4 mounteded on the frame of each of the wrapper rolls 2, 3 and 4 is a respective sensor roll 16, 17 and 18.
  • Each sensor rell is a comparatively light roll which is arranged to engage the strip 10 and be displaced by the leading edge or the step in the strip, and to respond to the displacement so that the signal indicative the leading edge or step is produced e.g. by an accelerometer or pressure sensor which is connected to the sensor roll.
  • the sensor rolls 16, 17 and 18 are designed not to press the strip into engagement with the mandrel.
  • one of the sensor rolls senses the passage of the leading edge or step in the strip
  • a control signal is produced and the associated wrapper roll is displaced outwards before the edge of the strip reaches that roll.
  • the wrapper roll can remain outwardly displaced for a predetermined time sufficient for the leading edge to pass the roll and then be returned to engage with the strip.
