Definitions

  • the invention relates to a method for the production and further processing of paper, wherein for the optimization of at least one further processing process in paper production determined information about the respective paper is transmitted to the respective further processing process and taken into account in this.
  • 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 is further referred to as MD (Main Direction) or X direction
  • the transverse direction as CD (Cross Direction) or Y direction
  • These features can be, for example, transverse and longitudinal profiles, fiber distributions, density, smoothness, moisture content, shrinkage behavior, roughness and friction values, resulting weakenings or cracking, and much more.
  • the respective further processing process can be, for example, a refining process, such as calendering, a coating or coating process, or a winding process.
  • a refining process such as calendering, a coating or coating process, or a winding process.
  • further processing processes may take place but also be a printing process, which usually takes place only at a customer of the paper manufacturer.
  • the paper web produced is first wound in full width onto a winding core.
  • This winding core is replaced cyclically, usually during production.
  • the resulting web-width winding roll is commonly referred to as mother roll or full tambour.
  • bar codes commonly used to identify a special parent role contain only very general information, such as date of manufacture and some target data.
  • the paper web wound on a mother roll has to be cut into several 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 winding rolls, which are called Railbahn- or finished rolling and are 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 carried out in a single machine, which is then often referred to as a slitter.
  • winding devices described above ie those for the production of parent rolls as well as those for the production of partial web or finished rolls, has in common that the train to be wound up to form a winding roll forms a winding nip with at least one winding roller on which it is supported or on it on or rests and which is accordingly referred to as a support or support roller.
  • These winding rollers which are in direct contact with the forming winding rollers, thus also constitute the directly acting tools by means of which the winding quality can be influenced.
  • the understanding of winding quality is determined from the perspective of the customer and today defined by numerous objective and subjective parameters. Simply speaking, the paper webs unwound from the finished rolls should be able to be processed without interruption and good printing results to be achieved.
  • the individual winding roll should be free of winding defects, in particular free of crevices, places, bars (which are also known as washboard pattern or rope markings), star formation, lateral positional shifts and markings on the material web surface.
  • the invention is therefore based on the object of further developing a method for producing and further processing paper in such a way that the winding structure is improved and, in particular, the conditions in the winding area are stabilized.
  • the further processing process is a winding and / or formatting process carried out in an offline double-takeup roll winding device, the double take-up roll winding device having winding rolls under the influence of which winding rolls are formed.
  • the winding process can be adapted to the expected conditions and can be customized to a large extent with regard to the different design of the finite material web sections to be processed.
  • the information determined within the Doppeltragwalzenwickelvoriques are transmitted to a paper machine and are taken into account in at least one process step of papermaking before the winding and / or formatting process.
  • the information obtained is used to prevent or reduce vibrations occurring.
  • the method according to the invention can be used particularly effectively, since occurring oscillations in today's winding processes usually represent the main cause of winding defects.
  • the ascertained information in particular with regard to the local distribution of detected parameters of at least one kind, in particular with regard to a periodic recurrence laid down via a winding scheme, is examined and / or processed and / or evaluated.
  • Double take-up winder takes as a group of other detected features.
  • the decisive factor is the strongest influence on the winding process. It is conceivable that the control / regulating unit is configured self-learning.
  • the determined information is used to control a passive damping device or repayment device.
  • the friction cross-section of a damping device For example, the friction cross-section of a damping device, the viscosity of an electrorheological oil of a damping unit or the effective lever arm of the mass of an absorber mass in real time or almost be varied in real time. This always ideal damping efficiencies can be achieved.
  • the determined information be used to control an active damping device or repayment device.
  • the information determined for controlling the shape and / or position of at least one winding roller involved in the winding process is used.
  • At least one winding roller is formed as, in particular from segments pressure roller and the information determined to a shift and / or to a dosage of pressurization, generation or change in magnitude of a line force in the direction of a developing between the winding roll and the respective winding roller or the respective segment forming winding nip are taken into account.
  • the determined information for controlling a winding hardness curve be taken into account.
  • the determined information for controlling an acceleration and / or velocity course be taken into account.
  • web breaks can be avoided or reduced in number.
  • the determined information relates to a finite section of a paper web wound on a spool and taken into account in the definition of a pattern to be selected for formatting within a single formatting process with regard to production that is as error-free as possible and / or error-free become.
  • information about the paper constituents or the paper composition is transmitted to the further processing process and taken into account therein, and or information about at least one property and / or composition longitudinal profile, which has been determined during papermaking, is transmitted to the further processing process and taken into account therein; and or in that information about at least one property and / or compositional cross-profile, determined in papermaking, is transmitted to the further processing process and taken into account therein; and or that information about at least one longitudinal and at least one transverse profile of the paper web relating to data relating to the paper web determined during the paper production is transmitted to the further processing process and taken into account therein; and or that position-related shrinkage values are taken into account.
  • the single FIGURE shows a Doppeltragwalzenwickelvorraum in a winding and formatting process WP as a successor process NP of a divided into individual process steps PS but continuously operating Papeierher einslui is feasible.
  • Wrapping rollers 15 are formed in the winding bed formed by two winding rollers formed as carrier rollers 2, 3.
  • WP growing bobbins 15 takes a divided into segments 5 Antikwalze 4 influence.
  • the position and the pressurization F of the segments 5 can be influenced via a control / regulation unit 11 of the double carrier roller winding device 1. This receives from a plurality of different sensors 10 detected information I from the control / regulation unit 12 of the paper machine 14. Both control / regulation units are connected via a data network 13.
  • the pressure roller 4 is provided in the illustrated embodiment with an active eradicator 7und one of the two support rollers 2,3 with a likewise active damping device 6. These devices can also be influenced under the influence of the transmitted information (I).
  • the transmitted information (I), depending on the sensors (9) detected by the sensors 9 provided here in the Doppeltragwalzenwickelvorraum also influence the driving data of Doppeltragwalzenvortechnisch, so for example their speed, acceleration and load curves or these generating facilities.
