Definitions

  • the invention relates to a winding method for the production of finished rolls, which are wound from longitudinal webbing of a moving paper webs under the action of winding rollers in a common, extending in a transverse winding bed, wherein by means of a continuous or segmented pressure roller one, during a winding process a Maximum line load on the resulting finished rolls is exercised.
  • paper or the terms paper web “or simply” web “used in the further description due to the web shape usually present in the production or further processing process should be understood in the broader sense in connection with the present specification, and those by the person skilled in the art In the narrower sense differentiated webs of cardboard, cardboard or tissue with include.
  • 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 full width onto a winding core. This core is cyclical, as a rule during production, replaced.
  • 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 wound into so-called partial web or finished rolls and issued together as a so-called roll throw.
  • the pattern can be changed from roll throw to roll throw.
  • the slitting and winding is conveniently done in a single machine, which is widely referred to as a slitter-winder.
  • such a slitter rewinder consists of a unwinding device, a cutting section and a roll-up device, wherein the cutting section has a number of mostly disc-shaped cutters adapted to the possible divisions.
  • the person skilled in the art distinguishes between two basic types of construction, namely the support roller and the back-up roller. This also applies if at least one of the winding rolls forming part of the winding process - ie partial web rolls or finished rolls - is replaced by a belt which revolves around rolls.
  • Characteristic of the roll carrier type is a retractor, in which the entire roll throw in a winding bed, which consists of two support rollers, is wound on winding tubes.
  • the winding tubes of the roller throw can be axleless by tensioning or guiding heads or, in rarer cases, through the winding tubes introduced winding shafts are kept.
  • 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 invention is therefore based on the task of stabilizing the conditions when winding finished rolls in a winding bed and in particular to avoid or at least reduce high oscillation amplitudes of the forming finished rolls and / or the winding rolls acting on them.
  • the object of the invention is achieved in a winding method of the type mentioned in that over a proportion of at least 40%, preferably at least 70%, more preferably at least 85% of the total diameter of the resulting finished rolls, at least 70%, preferably at least 80%, completely preferably at least 90% of the maximum value of the line load is exerted on the forming finished rolls.
  • finished rolls of high quality are formed.
  • the forming finished rolls under increasing diameter also form an increasing weight that forcibly precipitates as a line load in the two Auflagenips to the two, the winding bed forming, designed as a support roller winding rollers. Since the maximum line load, which is a finished roll, or the located in it, superimposed winding layers of paper tolerated, one controls the only by the pressure roller at the beginning of the respective winding process a significant line load is applied, which from a mean diameter usually only for extensive contact maintenance is used.
  • the maximum value is at least 20 N / cm, preferably at least 35 N / cm, very preferably at least 56 N / cm.
  • the maximum value of the line load for those finished rolls which are located transversely at marginal areas of the winding bed assumes about 1% to 12%, preferably 3% to 8%, most preferably 4% to 6% higher value, as the maximum value in the middle area of the winding bed.
  • the respective line loads are steadily lowered at the end of the respective winding process.
  • the winding method is used in winding relatively strong compressible paper types.
  • target and actual data of the line load (s) can be compared.
  • unwanted local differences can be determined and counteracted an impending loss of contact in a timely manner.
  • the winding method according to the invention can be ideally matched to each individual winding process.
  • a local distribution of the line load seen over the transverse direction can be adapted to the incoming actual profile of the paper web or of the individual partial webs to be wound. If appreciable changes in the longitudinal profile of the paper web are also to be expected, these data can also be influenced by the control of the pressure roller or its segments, and the line load applied can be adapted quickly to the requirements.
  • the term maximum value does not refer to an instantaneous peak value, but rather is intended to characterize the highest nominal value, which certainly includes certain, in particular short-term, fluctuations.
  • the pressure roller or at least individual segments of the pressure roller in the course of the winding process over the circumference of itself forming finished rolls or around the scope of at least one forming finished roll, moves.
  • all winding rollers are attenuated transition-free over the entire, occurring in a winding process vibration frequency range.
  • damping process is controlled and / or regulated at least in sections by means of a control / regulation unit.
  • the user can also effectively counteract oscillations that are composed of overlapping vibrations.
  • a winding device 1 is shown in the form of a relevant here roller carriage, in which from one to be unwound in an unwinder 2, material web M first in a longitudinal separation section 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.
  • the control unit serves the entire handling of the winding device 1 and is inter alia with the winding rollers 6,7, 13 involved in the winding process and all, not numbered here, drives and the sensors 16 exemplified in connection. 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. Then information I, here for example information about current cross and / or Longitudinal profile fluctuations of the material web M are transmitted. This can be done via a disk, which is then advantageously unmistakably connected to its associated parent role, but preferably is done over a data network and is then advantageously suitable for real-time control / regulation.
  • a line load L is exerted by means of a pressure roller 13, which here has individual segments, which are lined up in the Y direction, segments 14.
  • FIG. 2 is now a single example to illustrate the method according to the invention on the basis of so-called driving data or concrete so-called load curves of the winding process by means of the pressure roller on the forming winding rollers exerted line forces shown.
  • the abscissa shows the diameter D of the forming finished rolls in%, above this the ordinate shows the course of the line forces in N / cm.
  • the range A is, if you count only the full line load L max already slightly over 40%. / 0% of the maximum line load is over 70% of the Diameter growth on. In the right part of the picture you can see the steadily falling curve towards the end of the winding process.
  • the dash-dotted lower curve represents the driving style for the two marginal winding rollers of one, located in a common winding bed set of rollers.
