Definitions

  • the invention relates to a reel 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 at least one winding roll to which at least one roller mounted in a roller bearing during winding, and at least one movable roller bearing over a damping means, is connected to a support comprising a cylinder and a piston arranged therein movable.
  • the invention further relates to an advantageous method 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, by means of a roll winding device.
  • 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 will be referred to as X-direction
  • the transverse direction as Y-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 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 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 roles come together, as a complete litter, wound. 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.
  • each individual roll to be wound is wound in a separate winding station.
  • the rollers are supported during the winding process on a support roller.
  • the Railbahn- or finished rolls are wound in their winding stations on winding tubes, which are each held by an imported pair clamping or guide heads.
  • the rollers are driven either via these clamping or guide heads with center winding or on the at least one support roller with circumferential winding or combined.
  • 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) to form resonances with the support rollers of the reel winder, which can lead to a fierce, sometimes rapid "rocking" of the entire machine.
  • windings can be ejected from the winding bed.
  • the forming roll takes the state of a 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. Paper-technological correlations, such as compressibility or coefficient of friction of the web, then lead to inhomogeneous roles.
  • the winding structure is often not satisfactory as a result. Especially with winding-critical paper types, ie paper types whose Frictional coefficient is above 0.55 and in particular above 0.7, the winding structure is often still unsatisfactory under high production speeds in the result. From this, the productivity, that is primarily the winding speed, can barely be increased beyond a safely implementable level of 2800 m / min.
  • the invention is therefore based on the object to further develop a device for winding a web on a winding roll such that the winding structure improves and in particular the conditions in the winding area are stabilized.
  • the object of the invention is to improve the winding structure over long process sections and to stabilize the winding process.
  • the object of the invention is achieved according to the device in that a friction-free seal is provided between cylinder and piston.
  • a friction-free seal is understood to mean a seal which is friction-free in the technical sense, or at least largely friction-free. This means that negligible small coefficients of friction should be included in the term "frictionless”.
  • a frictional seal acts namely, to overcome their static coefficient of friction, such as a locking of the damping means.
  • the Haftreibbeiwert commercially available seals may well be 0.6 to 0.85, so here first considerable energy is rigidly passed through to the support, or reflected in adverse winding structure, in particular in non-circularity and regional hardenings until the damping agent begins to take effect ,
  • a damping means deprives a system of strain energy work. In this way, the amplitudes of the vibrations and thus the risk of dangerous resonances are reduced.
  • the energy is usually converted by friction into thermal energy, which is why it is particularly surprising according to the invention to exclude such an effect at a very specific location in order to achieve the best possible damping effect.
  • a damping means which has a cylinder and a piston movable therein, comprises at least one pressure chamber, in which a damping medium is that under piston load a pressure can be suspended and its friction work, and thus its degree of damping, generally adjustable or adjustable via a valve position is.
  • a winding roll which can be calmed from the beginning by means of a device according to the invention forms substantially more homogeneously and causes far less self-excited vibrations in the further winding process.
  • the whole process is much quieter and more stable and produces higher quality bobbins. Also are higher Production speeds and sharper acceleration or deceleration processes possible.
  • the cylinder is designed as a double-acting damping cylinder. In this way, the positive and negative amplitudes of nascent or adjacent vibrations can be reduced particularly effectively.
  • the friction-free seal is designed as a non-contact seal.
  • a seal is referred to as non-contact, when the two sealing gap forming parts with and without movement and without auxiliary energy are permanently separated from each other by a finite gap.
  • seals offer the advantage of being wear-free and of having no changes in their sealing effects. Also, heat transfer of the sealing gap forming parts are low and no restriction on permissible relative speeds to observe.
  • non-contact seal is designed as a gap seal, labyrinth seal or sealing air seal.
  • Gap seals offer the advantage of relatively simple production, although here, of course, to ensure compliance with predetermined tolerances and an accurate machining of the surfaces. Also here are breaks of a, from the sealing medium used, in particular from the damping medium used, in particular from the used damping oil formed, sealing film at correctly selected ratio of gap height and gap length hardly expected. Labyrinth seals offer an increased sealing effect, since the effective gap length is artificially increased and the sealing medium undergoes several deflections.
  • Sealing air seals provide the safest shield against leakage and penetration at the sealing point, but the sealing air must be introduced via a supply unit in the sealing gap.
  • the non-contact seal has a gap height which is between 0.008 mm and 0.1 mm, preferably between 0.025 and 0.065, very preferably between 0.03 and 0.045.
  • the gap length is between 5 mm and 350 mm, preferably between 12 and 100, very preferably between 18 and 60.
  • the length of all center lines is added.
  • the at least one roller is a support roller, a support roller or a support roller.
  • 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.
  • Roll-wrap devices equipped with carrier rolls are generally the most vibration-prone and provide the primary target field of the present invention.
  • backup roller winders are generally not as susceptible to vibration, they are used to handle particularly delicate and critical types of paper, and for that reason can also provide an important field of use for the present invention.
  • Support rollers are used in addition to their basic function of increasing the winding hardness at the beginning of the winding process, today often to stabilize the winding rollers already in the progressive stage of education and are then increasingly equipped with a damping device. Taking into account the effect mentioned at the outset that a damping means which has a frictional seal acts like a rigid bearing until the static friction is overcome, the platen roller acts in this phase as a disturbance variable additionally acting on the winding rollers. This is inventively avoidable for the first time.
  • damping means forms part of a passive damping device.
  • a passive damping device generally offers the possibility to reduce applied vibration energy, that is the Amplitude deflection of the present state of vibration to reduce.
  • such a damping device can be very effective, since even the lowest vibration energies are at least partially consumable by means of a device according to the invention. Then offers a passive damping device has a high impact at a very clear cost.
  • damping means forms the only part of a passive damping device.
  • damping means forms part of an active damping device.
  • the (counter) pressure exerted on the piston via the damping medium can be changeable and counteract, for example, an impending load. Since the piston has a mass, it is about rapid pressure changes to vibrate, which can be brought into superposition with the vibrations to be combated, whereby they are reducible. Then one speaks technically correct of a repayment, which should be included in the meaning of the present document by the term "damping".
  • Rubber elements have in principle a good damping behavior compared to machine-generated vibrations. Often, however, their applicability is structurally meaningful little feasible because of spatial limitations. Your work area is at least indirectly related to the so-called loss factor D L , which is dependent on material and load and can assume meaningful values between 0.20 and 0.35 for various types of rubber to a resonance range. Thus, from this loss factor D L and the necessary damping surface is at least indirectly dependent.
  • the rubber deformation element which absorbs deformation, finally emits the extracted energy into heat. However, a heated rubber element then has other damping properties. Finally, under continuous load, such a rubber element tires relatively quickly.
  • the rubber element is only loaded with a vibration region tailored to it, by means of another functional group of the damping device, it can perform excellent damping work for a long time.
  • the rubber element also performs relieving work with respect to moving machine elements, in particular the piston unit of the damping means.
  • roller bearings are arranged with a finite radius, in particular between 350 mm and 2050 mm, very particularly between 600 mm and 900 mm, movable about a pivot point.
  • roller bearings are arranged to be linearly movable.
  • roller bearings are so arranged linearly movable, which is a, with the piston operatively connected, piston rod largely free of transverse forces by a, defined by the intended seal, the sealing area is movable.
  • an alignment device is provided, by means of which a direction of movement of the at least one roller bearing can be aligned.
  • piston rod and the cylinder may also be advantageous if the piston rod and the cylinder have a surface with a particularly low coefficient of friction at least in the sealing region and, in particular, are mechanically and / or chemically tempered for this purpose.
  • roller bearing is connected by means of a frictionless movable spring assembly movable with the support.
  • the damping device can be used without an initial fault.
  • the wide damping range provided by the damping means in particular the damping capability of even the smallest excitations, can be transmitted to the entire damping device. Also, sources of error in the structural design of the damping device can be avoided.
  • an alignment device is provided, by means of which a direction of movement of the at least one roller bearing can be aligned.
  • piston rod and the cylinder may also be advantageous if the piston rod and the cylinder have a surface with a particularly low coefficient of friction at least in the sealing region and, in particular, are mechanically and / or chemically tempered for this purpose.
  • the damping means has a power range which can be defined by a damping capacity of even the smallest movements of the roller bearing of less than 5 mm per second, preferably less than 1 mm per second, more preferably less than 0.5 mm per second ,
  • the present document also speaks of macro-vibration ranges and micro-vibration ranges, wherein the Macro vibration ranges are to describe the commonly perceived, resulting oscillations, while under the micro-vibrations superimposed vibrations, usually higher frequency, sometimes over 8 Hz or 10 Hz, and lower amplitude, are understood.
  • control unit By recording individual, in particular several, of the mentioned parameters, a reliable data supply of the control unit is ensured and modern control mechanisms can be used.
  • control / regulation unit is the instantaneous requirements present in the process quickly adaptable and miscalculations due to changing process parameters can be avoided.

  • the degree of damping is changed continuously or discretely via a pressure change of a pressure medium during the winding process.
  • the degree ie the intensity of the acting damping measures, on the other hand, can be changed without any interfering influence on the winding process.
  • a change in the degree of damping can significantly widen the range of action of the damping device / means used, and the effects therein are more critical on individual oscillating elements, in particular winding rolls and rollers Vibration ranges by rapid bypassing or driving through, reduce.
