Definitions

  • the invention relates to a carrier roll winding machine for winding a material web, in particular a paper or board web, according to the preamble of claim 1.
  • a carrier roll winding machine for example, from DE 101 15 862 A1 known.
  • Carrier roll winding machines are used for winding paper or cardboard webs to wound rolls.
  • the carrier roll winding machines have, for example, two driven carrier rolls, on which the winding rolls rest during winding side by side with aligned sleeves. It is also known to influence the hardness of a supported on two parallel support rollers winding during winding by load distribution of the roll on the support rollers. For this purpose, rolls of the same or different diameters are used, which are arranged in different horizontal planes. The influencing of the winding hardness is done by so-called load rollers. The additional load on the sleeves or reels is particularly important at the beginning of the winding process. This is intended to achieve a defined winding hardness.
  • the winding hardness is more and more determined by the increasing weight of the winding roll.
  • the pressure of the loading roller is accordingly reduced until it almost floats over the winding roller. From this point on, however, it is no longer possible to a significant degree to influence the winding hardness via the pressure roller; This is determined exclusively by the nip geometry and the own weight. However, since the optimal winding structure has a decreasing winding hardness to the outside, a further relief of the winding roll would be in the nips with the support rollers desirable.
  • Carrier roll winding machines with carrier rolls of different diameters are also used. It is known that when winding on the support roller of smaller diameter receives a harder winding than during winding on the support roller of larger diameter. Attempts have been made to avoid the disadvantage that, as the winding diameter increases, the inner region of the roll is radially compressed by the outer region, since the winding process has begun with a greater winding hardness. However, this type of winding resulted in too high a hardness of the coil in the outer region. It created wrinkles, places and cracks.
  • a carrier roll winding machine is further from the EP 0 829 438 B1 known, according to which the winding roll is wound above a support roller.
  • the side of the winding roll a support device is provided by the winding roller is at least partially supported during the winding process.
  • the support device is displaced during winding along the circumference of the winding roll.
  • the structure of the wound roll to be produced is profiled in the direction of the width or the circumference by loading or supports via independently controllable load-carrying units.
  • this object is achieved in a carrier roll winding machine of the type mentioned above in that the guide points of the rockers are above the axis of the first support roller.
  • the second and the third support roller have a smaller diameter than the first support roller.
  • the second and the third support roller elastically, in particular by means of a spring, a pneumatic or a hydraulic cylinder or an elastic coating, are supported against the winding roll.
  • a winding machine ( Fig. 1 - 4th ) has a support roller 1, which is positioned substantially vertically below a winding tube 2.
  • the winding tube 2 is connected to a winding of a material web to a winding roll 3 ( Fig. 2-4 ).
  • Side of the winding tube 2 are two support rollers 4, 5 on the winding tube 2 and on the winding roller 3 at.
  • the support rollers 4, 5 are mounted in each case by means of rockers 6, 7 pivotable about guide points 8 and 9, respectively.
  • the guide points 8 and 9 of the rockers 6, 7 are in this case above the axis of the first support roller first
  • the coiled cores 2 are arranged side by side in the winding tube set from both sides Guiding heads tensioned in the axial direction.
  • the individual winding tube 2 or a plurality of winding tubes 2 is located on or in the vicinity of the zenith, ie the uppermost point, on the circumference of the support roller 1.
  • the support rollers 4, 5 hold them in position and provide the necessary line loads for transmitting the torques necessary for the winding structure.
  • the back-up rolls 4, 5 have a smaller diameter than the back-up roll 1.
  • the support rollers 4, 5 preferably pivot on a circular path to the outside.
  • the winding tubes 2 are guided on a tilted to the vertical guide upwards.
  • the back-up rollers can also perform other forms of pivotal movements in other embodiments.
  • the support rollers with increasing diameter of the winding roll 3 exert an ever decreasing pressure on the winding roll 3 and finally take over more and more the function of a support roller, as it has the support roller 1.
  • the winding roller 3 grows substantially vertically above the support roller 1 upwards.
  • one of them is position-controlled and the other pressure-controlled.
  • each (not shown) measuring arrangements for determining the position or the contact pressure of the support rollers 4, 5 with respect to the winding roll 3 is present, the measurement results determined by each of control devices for controlling the optimum pressure and the optimal position of the support rollers 4, the fifth pass on.
  • the back-up rollers 4, 5 exert a controllable pressure on the winding roll 3 with increasing diameter of the winding roll 3 and finally more and more assume the function of a supporting roll, such as the back-up roll 1.
  • the pressures are chosen so that the specific nip loads of all three back-up rolls 1, 4 and 5 are as low as possible be kept to avoid the winding errors or to produce bobbins with larger diameters can.
