  • the invention relates to a reel winder in which a winding system can be formed comprising a winding bed formed from winding rollers, at least one forming reel and at least one one-piece or multi-segment platen, wherein the winding rollers and the platen roller in the axial direction can be changed under a force Have bending lines and generatrices.
  • the invention relates to methods for producing winding rolls in a roll winding device in which a winding system can be formed comprising a winding bed formed from winding rollers, comprising at least one forming winding roll and at least one one-piece or multi-segment platen roller, wherein the winding rollers and the platen roller have in the axial direction bending lines, which are influenced by the changing in the course of the winding process influence of force.
  • the bobbins can arise from a longitudinally divided or divided webs in partial webs.
  • Paper webs are produced in relatively large widths of up to more than 11 m in a paper machine.
  • the production is almost endless.
  • the machine direction of the paper machine defines the longitudinal direction for all machines and devices located in the paper factory and the transverse direction perpendicular thereto in the horizontal plane.
  • the longitudinal direction X-direction, the transverse direction as Y-direction and the height direction perpendicular to a plane defined by these two directions are referred to as Z-direction.
  • the paper web produced is wound in a first winding process in full width onto a winding core. This winding core is replaced cyclically, usually during production.
  • the resulting web-wide winding is commonly referred to as mother roll.
  • the paper web wound on a mother roll has to be cut into a plurality of parallel partial webs whose widths are suitable for the respective later user. These widths can vary greatly from case to case, so that the division of the paper web is usually made according to an individually definable pattern.
  • the partial webs are then rewound into reel rolls, more precisely to what are known as partial web or finished rolls, and jointly issued as a so-called reel roll.
  • the pattern can be changed from roll throw to roll throw.
  • the slitting and winding is conveniently carried out in a single machine.
  • a thus equipped winding device is then widely referred to as a slitter-winder.
  • such a slitter rewinder thus consists of a unwinding, a cutting section and a retractor, wherein the cutting section a Having adapted according to the possible divisions number of mostly disc-shaped cutting.
  • Characteristic of the carrier roller type is a retractor, in which the entire roll throw is wound on winding tubes in a winding bed, which consists of two winding rollers designed as support rollers.
  • the winding cores of the roll throw can be held by means of tensioning or guide heads or, in more rare cases, through winding shafts inserted into the cores.
  • the rolls are wound up together, as a complete throw. As a rule, this is done by means of a circumferential winding, for which purpose at least one of the two support rollers can be driven. If a winding shaft is used, a center winding or a combination of both can also take place.
  • additional pressure rollers are used, which provide in the initial stage of each winding for a desired level of winding hardness and should take over the course of the winding process often stabilizing tasks.
  • the winding to be produced hardly takes on an ideal round shape. Small winding errors, for example due to slight profile fluctuations of the paper web to be wound, add up every full wrap. Due to the periodic recurrence of the respective winding defects of the rotating coil, vibrations of corresponding frequency are formed depending on its circumference and peripheral speed.
  • the excitation frequency is always greater (with increasing peripheral speed, the same position of the winding more and more often passes through the same winding gap) and the exciter amplitude is increasingly violent (at the same time as its winding diameter and its unevenness and the effective weight increases).
  • the then uncontrolled oscillating against each other rollers exert irregular or periodic impulses to the forming bobbins, the out-of-roundness increases with it. This form on the one winding error.
  • the excitation initiated by the winding rollers themselves are in turn larger.
  • the winding rollers and the support roller are designed and / or influenced such that their bending lines or their mutually facing surface lines can be changed synchronously with each other.
  • the term "synchronous with one another” means that the ratios of the spatial orientation of the mutually synchronously movable body, so the winding rollers and the platen roller, with respect to their bending center lines or their mutually facing surface lines, even under change, in particular increase their distance to stay the same during the winding process.
  • these lines can follow a straight line or a curve, form parallels in their spatial orientation and simply speaking their parallelism on the winding process is maintained, even if the distance of the named lines of course with the growth of forming winding rolls increased.
  • winding rollers perform matching movement in terms of time, amount and direction when viewing one of the named line types.
  • the bending line or its mutually facing surface lines of the support roller under maximum load corresponds to the bending lines of the winding rollers under minimal loads and under minimal load corresponds to the bending lines of the winding rollers under maximum loads.
  • the winding device is formed by a Doppeltragwalzenwickelvorraum and the minimum load of the platen roller in a range between 0.1 N / cm to 12 N / cm, preferably between 0.5 N / cm to 5 N / cm and their maximum load is in a range between 15 N / cm to 65 N / cm, preferably between 20 N / cm to 45 N / cm, while the minimum load of the winding rollers, which are then designed as support rollers, lies in a range between 0.3 N / cm to 13 N / cm, preferably between 1 N / cm to 6 N / cm and their maximum load is in a range between 15 N / cm to 100 N / cm, preferably between 20 N / cm to 80 N / cm moves.

  • winding rollers forming the winding bed have the same diameter.
  • the diameter of at least one winding roller at least 850mm, preferably at least 920 mm.

  • the platen roller consists of several segments, which are arranged on a common traverse and at least one segment individually designed with respect to the traverse, in particular in the Z direction, adjustable.
  • the pressure roller or at least individual segments of the pressure roller in the course of the winding process over the circumference of the forming winding rollers or around the circumference of at least one forming winding roll is movable.
  • the pressure roller or at least one segment of the pressure roller, preferably in synchronism with the winding rollers is designed to be drivable.
  • the winding rolls forming in the winding system can additionally be influenced and stabilized particularly well.
  • the pressure roller or its segments to an elastic coating on.
  • the roll winding device preferably has a cutting section in which a material web, which can be treated to form the winding rolls in the roll winding device, can be divided in at least two partial webs in the longitudinal direction.
  • the cutting section preferably has a plurality of adjustable separating means for individual format selection of the part webs arising from the material web.
  • partial webs can be produced from a material web, which can then be wound to form part web rolls which form together.
  • a roller winding device can be used particularly effectively, since the treatment of sub-train rollers forming side by side usually leads to particularly pronounced vibration problems.
  • rollers and the winding roll (s) forming the winding system are in contact via nips, in which case preferably sensors are provided by which the maintenance of the nips and preferably the forces acting there can be determined discretely or continuously.
  • Suitable sensors are optical means or means for determining force, preferably in the form of pressure-measuring or strain sensors, which are then preferably inside the rollers to be arranged, in question. Both sensor types are inexpensive and reliable.
  • a control or regulating device which is preferably connected via a data network to at least one device preceding the winding device for producing and / or refining a material web.
  • the lines are exactly adaptable to the requirements coming to them and an unintentional deflection of a single or multiple lines can be avoided.
  • the maintenance of constant internal conditions in the winding system is thus particularly secure even with non-uniform material webs feasible.
  • the sensors provided within the winding device are also suitable for real-time control.
  • the object of the invention is achieved in that the bending lines or mutually facing surface lines are kept synchronous in the winding process.
  • the generatrix lines which form the inner region of the winding system always form during the winding process from successive integral lines of the circumference of the roll.
  • winding rollers and the at least one support roller are held in synchronous oscillations in the winding process in the case of forming vibrations.
  • the winding rollers and the at least one support roller are kept in constant contact with the at least one forming winding roller.
  • Constant contact is still present even when interruptions occur, which in themselves last only a few milliseconds. In some cases, one can still speak of a "permanent contact" in sufficient form, even if the interruptions are shorter than a few centiseconds.
  • a winding device 1 is shown in the form of a carrier roller in which from one to be unwound in an unwinder 2, material web M first in a longitudinal separation part 3 partial webs M 'are generated, which are then wound in a take-up device 4 to sleeves 5 to finished rolls 12.
  • Two of the winding rollers involved are formed as support rollers 6 and 7, which are both supported by elastic bearings 9 here.
  • the first support roller 6 seen in the web running direction x is equipped in the illustrated embodiment with an active damping device 10, which is connected to the control unit 15 of the winding device 1.

At least part of the intended sensors 16 serves in particular to detect undesired vibration states.
  • the control / regulation unit 15 can also be in operative connection with a control / regulation unit of the paper machine for improved use of the winding device 1.
