Definitions

  • the invention relates to a roll winding device for winding a material web, in particular a paper or board web, on at least one winding core, preferably a winding tube, to a winding roll with support at least one roll forming a nip with the winding roll, wherein the roll winding device with at least one electronic means for compensating vibrations of the at least one roller and / or the winding roller is equipped, wherein the at least one roller is driven by at least one drive motor by a rotational degree of freedom
  • 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 referred to as the X direction
  • the transverse direction as the Y direction
  • the vertical direction perpendicular to a vertical plane defined by these two directions are referred to as the Z direction.
  • the paper web produced is 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.
  • the wound on a mother roll paper web must be cut into several parallel partial webs whose widths are suitable for each subsequent 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 Operabahn- 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 advantageously carried out in a single machine, the so-called slitter, which is generally referred to as a reel winder for the purposes of the present application, since, for example, even in the pure rewinding of a mother roll without format changes at least a portion of the possible winding problems can occur.
  • a roll cutting device essentially consists of a unwinding device, a cutting section and a roll-up device, wherein the cutting section has a number of mostly disk-shaped cutters adapted to the possible pitches.
  • Characteristic of the carrier roller type is a retractor, in which the entire roll throw in a winding bed, which usually consists of two support rollers, is wound on winding tubes.
  • the winding tubes of the roller throw can be held by means of tensioning or guiding heads or, in rarer cases, through winding shafts inserted into the winding tubes.
  • 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.
  • winding rolls wound around a band and / or around the forming winding rolls from a support into a support position are also understood to mean supporting or supporting rolls.
  • Both machine types generally use additional pinch rollers which provide a desired level of winding hardness, especially at the initial stages of each winding.
  • the winding to be produced hardly assumes an ideal round shape. Small winding errors, for example, due to slight profile fluctuations of the paper web to be wound, add up with each full wrapping. In the further course, the winding rollers form hardenings in these areas. 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 grows with increasing winding roll diameter and its unevenness and the effective weight).
  • the probability increases greatly that form during this complex process vibrations that are suitable (via integer harmonics) with the support rollers of the reel winding resonances, which can lead to a fierce, sometimes rapid "rocking" of the entire machine.
  • windings can be ejected from the winding bed.
  • the forming winding roll assumes the state of an anisotropic rotor.
  • the reason for this are transverse profile fluctuations of the paper web, which add up with each wrapping. It can then come with each revolution also contact losses or at least different line loads.
  • the degrees of freedom of the rollers mean the translational movement directions in the X, Y and Z directions as well as the directions of rotation about these axes.
  • At least one drivable roller can be controlled and / or regulated in the direction of movement of at least one further degree of freedom.
  • At least one roller can be controlled and / or regulated in at least two further degrees of freedom.
  • At least one roller can be controlled and / or regulated in the direction of movement of at least one of the degrees of freedom in a static and a periodic component.
  • the term "static” should of course not be permanent unchanged state to be understood.
  • the static component is to be understood here as a control technology and, for example, reflects the planned control using the provided control curve. With respect to the roller of a reel-winding apparatus, such a curve usually includes an acceleration phase, a constant-speed phase and a deceleration phase. Relative to a damping device, the static component refers to the active or passive damping of the currently applied resulting vibration, while the periodic component of one, this vibration superimposed, usually higher-frequency, vibration corresponds.
  • the present document also speaks of macro-vibration ranges and micro-vibration ranges, the macro-vibration ranges are to describe the commonly perceived, resulting vibrations, while under the micro-vibrations superimposed vibrations, usually higher frequency and lower amplitude, are understood.
  • At least one roller can be controlled and / or regulated by means of a feedback and / or a feedforward influence.
  • action and reaction can be suitably used in the winding process to dampen vibrations depending on the phase position.
  • At least the periodic component is high-frequency controllable and / or controllable.
  • Micro-excitations usually occur at high frequency and with minimal amplitudes. You can best address them with high-frequency control mechanisms. It may well be preferable to use frequencies equal to 8Hz, in particular frequencies equal to 10Hz.
  • rollers in particular the pressure roller to calm the winding roller about its own axis is driven so that the static portion of the peripheral speed of the forming winding roll corresponds, and the periodic proportion of, by a rocking motion of the winding roll induced, superimposed torsional vibration of the pressure roller corresponds.
  • the periodic component can be adjusted in phase or adjusted in phase.
  • At least the periodic components of the motion control of at least two rollers can be aligned in opposite phase to one another.
  • rollers in particular at least the pressure roller, has an elastic cover.
  • the pressure roller with a particularly large lever arm acts on the, around the hubs or about an imaginary axis in the winding bed moving, in particular rocking, winding rollers and the pressure roller also has the lowest moment of inertia, it is particularly suitable for influencing.
  • rollers in particular at least the support roller, is driven segmented and in particular also controllable and / or controllable.
  • roller segments can be used, which are shorter than the material web width in the Y direction.
  • rigidity of the rollers can be advantageously influenced and from this synergy effects to the above-mentioned advantages can be achieved.
  • nip contact can be determined by means of at least one sensor.
  • roller and the winding roller interact with each other only when the nip contact is established. Therefore, it is important, especially in vibration-reducing measures, to be informed discreetly or continuously about the presence of nip contact.
  • At least one roller with an active or passive damping device can be damped.
  • At least one roller with an active or passive repayment device can be damped.
  • At least one roller, in particular the support roller, segmentally by means of the damping device or the repayment device is damped.
  • a roller in particular the support roller is arranged to be movable in entirety and / or in segments along the circumferential direction of the winding roller.
  • a take-up area which has two support rollers 1, 2, of which at least one is driven.
  • the support rollers 1, 2 form a roller bed in which a plurality of winding rollers 5 adjacent to one another in the Y direction rest on the support rollers 1, 2 during winding.
  • a material web M in particular a paper or board web, cut before winding into several individual webs, which then by the nip between the support rollers 1, 2 or laterally to the coat of one of the two support rollers 1, 2 around the roll bed are guided, where they are wound up in aligned rows of sleeves 4.
  • the support rollers 1, 2 each form a nip with the winding roller. 5
  • a support roller 3 forms, in the illustrated case via an elastic cover 8, an additional nip with the winding roller 5.
  • the support roller 3 is segmented in the Y direction and each individual segment is driven by its own, torsionally stiff drive motor 6.
  • the support roller 1 and the support roller 2 are driven by a drive motor 6 disposed within its roll shell.
  • the invention can be used even if only a single roller is used as a support roller for the cut longitudinally paper webs.
  • the individual winding rollers 5 are usually supported alternately in an eleven o'clock position and in a one o'clock position relative to the roller 1,2,3 acting as a supporting roller.
  • the winding rolls 5 can also be located at other, symmetrically opposite positions in the region of the two upper quadrants of the support roll.
  • roller 1,2,3 is driven by means of an external drive motor. It is only important that the connection of the drive motor to the roller of high rigidity, changes in the drive power (motor current, torque, speed) are passed through the roller quickly and unadulterated.
  • sensors for detecting vertical vibrations of the winding roll 5, oscillations in the nip direction and torsional vibrations, d. H. in the tangential direction of the support rollers 1, 2, be present.
  • at least one roller 1, 2, 3 is equipped with at least one sensor 7 for detecting nip contact.
  • the sensor 7 may be designed as an optical sensor. In the example shown, however, it is designed as a load sensor and is in contact with the respective roller shells. It is conceivable that the sensor 7 can circumferentially monitor a plurality of discrete sections.
  • the senor is designed to be suitable for detecting the entire roll surface, and thus any contact loss, as illustrated in the figure for clarity by the open gap h, in the respective nip between the individual rolls and Wrapping rollers 5 can detect.
  • contact losses are largely avoidable.
  • vibration-induced contact losses are avoidable or at least reducible.
  • Contact losses of the platen roller 3 due to cross profile variations are more difficult to prevent.
  • determining a loss of contact in the nip between the pressure roller 3 or a segment of the pressure roller 3 and the winding rollers 5 can then provide important information for the further control strategy.
  • the at least one sensor is in contact with a control unit 9.
  • control / regulating unit is also, directly or via interposed further control / regulating devices, also with the drive motors and optional existing damping or Eradication devices in operative connection.
  • the support roller 3 and its individual segments are equipped with eradicators 12, which are symbolically represented here by a ring around the driven axle.
  • the eradication devices 12 are in operative contact with the control / regulating device via contact lines or wirelessly.
  • the support roller 1 is driven by the control / regulating device 9 via its drive motor 8 by its rotational degree of freedom.
  • the arrow S 1 - 1 indicates the static component while the pair of arrows P 1 - 1 represents the superimposed periodic component.
  • the forming in Nipcardi linear degree of freedom of the support roller 1 is indicated by the arrow S 1 - 2 .
  • the permitted movement is regulated by means of the active damping device 10.
  • superimposed periodic, that is, oscillating, components are introduced, which are represented by the pair of arrows P 1 - 2 and whose influence is of importance, in particular, in the case of actively initiated countermovement of the support roller 1.
  • the naming of the arrows results as follows: S for static component, P for periodic component, the first index names the roller, the second index the degree of freedom.
  • the periodic component is preferably controlled or regulated high frequency and moves advantageously in frequency ranges above 8 Hz.
  • the pressure roller 3 is equipped with a Tilger adopted 12, in the present case, only the first of the aligned in the Y direction juxtaposed segments of the pressure roller 3 is visible. The same applies to the cores 4 and the winding rollers 5 forming on them.
  • the pressure roller 3 is in the case shown at least temporarily over the winding process in a total of 3 degrees of freedom in static and periodic
  • the pressure roller 3 can only be controlled or regulated in 2 degrees of freedom, the path of the pressure roller counteracting the vibrations moves to an orbit. Again, this is often sufficient to achieve significant improvements in the winding process, since the individual bobbins 5 tilt only in rare cases to their front pages or swing back and forth in the transverse direction (Y-direction).
  • the oscillatory process initiating movements of the winding rollers 5 are represented by the arrows S 5 - 1 and P 5 - 1 and S 5 - 2 .
  • S 5 - 1 represents the desired winding speed
  • P 5 - 1 the vibration-generating periodic Mirkoanteil due to unevenness of the bobbin circumference
  • S 5 - 1 an exemplary rocking motion, as occurs when (via integer harmonics) meet resonance areas of each vibration partner.
  • the pivot point of the swinging motion can thereby change dynamically due to the growing roll diameter, vibrations and winding movements or temporary loss of Nipcard, dynamically.
  • control software which also anticipates machine-related disturbances and, in particular, is designed as a self-learning system.
