Definitions

  • the invention relates to a double-carrier roll winding machine for winding a material web, in particular a paper or board web, on at least one winding tube to at least one winding roll, wherein the at least one winding roll is at least during the winding process in a winding bed formed by two support rollers and wherein at least one of two support rollers is formed as a drive roller, which comprises a rotating and rotatable roll shell and a roll shell axially passing through and fixedly formed roll axis.
  • Material webs must be wound up on shipping or finishing rolls before they can be shipped.
  • reel cores usually winding cores are used, which are preferably made of cardboard.
  • the finished rolls are produced in that so-called mother or spool rolls, which are produced at the exit of a paper machine or after the calendering, unwound, cut in the longitudinal direction and then wound on each winding cores.
  • mother or spool rolls which are produced at the exit of a paper machine or after the calendering, unwound, cut in the longitudinal direction and then wound on each winding cores.
  • These cores are either on a support roller of a backup roll winding machine or laterally on this or the cores lie in one of two support rollers of a double carrier rolls winding machine formed winding bed.
  • German Utility Model DE 71 21 923 U1 is a support device for wound from material webs winding rollers known in which at least one of the two support rollers is mounted elastically. Due to the elastic support receives the one support roller with the same design of both support rollers to the other support roller different natural frequency, so that a summation of the vibrations of the two support rollers and thus a roller damage are largely excluded.
  • the invention is therefore an object of the invention to provide a vibration in terms of improved double-carrier rollers winding machine.
  • the drive roller has at least one inner, between the roll shell and the roll axis, a stator and a rotor having a drive motor whose windings are energized asymmetrically such that a radial Force is generated.
  • the radial force acts preferably diametrically to the asymmetric energization and allows the prevention of vibration in an efficient manner. In this case, the radial force can also be nachgfahren any vibrations.
  • the solution according to the invention enables an effective avoidance of vibrations in a double carrier roll winding machine. Since the vibration properties can be changed very quickly, both a passive solution and an active solution, that is, a solution taking into account current vibrations of the winding roll, for example by means of a control device acted upon by a control circuit conceivable.
  • the use of the solution according to the invention is particularly suitable for large working widths, preferably from a roll width greater than 7 to 8 m, and relatively slender support rollers, since the normally occurring disturbing vibration amplitudes can be reduced in this way, which in turn in order to achieve acceptable winding qualities in the winding roll is of importance.
  • the roll axis forms the stator and the roll shell the rotor of the drive motor, since this can best meet the practical and operational requirements of the double carrier roll winding machine.
  • this embodiment to the effect advantageous because it provides a very simple, but compact and low-maintenance design of the support roller drive.
  • the drive motor is preferably designed as a synchronous motor with a high number of pole pairs, since this embodiment offers maximum flexibility with regard to the suppression or avoidance of vibrations.
  • the synchronous motor has in this case preferably 4 to 12, preferably 4 to 8 pole pairs.
  • the drive roller comprises a plurality of drive motors which are arranged at a uniform or uneven spacing of from 1,000 mm to 2,500 mm, preferably from 1,250 to 2,000 mm.
  • the number of drive motors is not more than five, preferably between one and three. This mentioned number of drive motors with a corresponding distance is completely sufficient with regard to an effective prevention of vibrations taking into account the manufacturing costs for such a drive roller formed.
  • the drive motor preferably has a direction of action, which is directed towards the at least one winding roll lying in the winding bed and which is aligned in an angular range of 10 to 60 °, preferably from 20 to 40 ° to the vertical. This orientation makes sense in particular with regard to the damping of horizontal and vertical movements of the winding roll with associated vibrations.
  • the directions of action of several drive motors can be rectified or approximately rectified. Additionally or alternatively, the effective directions of several drive motors can also be aligned in an angular range of 5 to 20 °. This results in the advantage of a maximum adaptation to respective, possibly different operating conditions.
  • a further advantageous embodiment consists in that the roll shell is additionally rotatably mounted via radial bearings, in particular roller bearings, which are installed at the front ends of the drive roller.
  • the drive or drive motor according to the invention therefore does not require its own foundation for storage and does not need to be laboriously aligned, which represents a further advantage of the invention.
  • means for ongoing lubrication of the bearing points of the support roller are not necessary in an advantageous manner, but means for at least temporary cooling of the drive motor can for example very easily be accommodated in the roll neck.
  • At least one loading roller rests against the at least one winding roller, which is mounted via at least one adjustable damping device.
  • a loading roller for example, on the frame, in particular on the rocker mounted so that it presses vertically or preferably laterally against the winding roll to curb the rocking or vibration of the winding roll.
  • the loading roller can be fastened either on a rocker swingable about an axis of rotation or on a linear guide; the function of the loading roller is independent of whether it is guided on a straight line or a circular path.
  • the loading roller is inclined with respect to a passing through the center of the winding roll, the connecting line between the two support rollers at right angles intersecting perpendicular bisector, at least during most of the winding process, that is at least from reaching a predetermined winding diameter.
  • the at least one damping device is at least partially variable with a hydraulic fluid conducted through at least one hydraulic valve or at least partially with an electrorheological fluid (ERF) and / or ferrofluid whose viscosity can be varied via an electric or magnetic field , is operated. So can For example, vibration of the winding roll can be suppressed very well, which can also achieve a constant line force with this highly dynamic loading roller.
  • EMF electrorheological fluid
  • the preferred storage of the loading roller by means of at least one damping device allows high dynamics in the regulation of vibrations or irregularities of the winding roll, because unlike a hydraulic cylinder, which carries the load roller traverse and therefore does not allow high dynamics, not the entire mass the load roller traverse must be moved, but the damping is done exclusively by the setting of the at least one damper.
  • the load roller traverse is still moved by hydraulic cylinders; However, these cylinders are sluggish.
  • the flow property or viscosity of an electrorheological fluid or ferrofluid changes under the influence of an electric or magnetic field, that is, for example, a hydraulic pressure or a volumetric flow by changing the relevant field can be varied.
  • the flow properties of the electrorheological fluid or ferrofluid can be varied steplessly and reversibly.
  • the electrorheological fluids available today are in particular silicone oil in which polyurethane particles are dispersed. With increasing electrical voltage or field strength, the apparent viscosity of the electrorheological fluid in the field increases and the volume flow decreases.
  • the properties of an electrorheological fluid or ferrofluid thus allow, for example, a relatively simple, fast and very fail-safe load roller pressure control. In addition, targeted damping properties can be realized on the loading roller.
  • FIG. 1 shows a schematic side view of a double carrier roll winding machine.
  • This double carrier roll winding machine 1 is used to wind a plurality of juxtaposed material partial webs 2.1, in particular paper or board webs, on several in one of two mutually parallel support rollers 3, 4 winding bed 5 stacked side by side winding tubes 6 to bobbins 7.
  • the bobbins. 7 lie during the winding of the material webs 2.1 in training two respective nips N3, N4 on the support rollers 3, 4.
  • the web 2 is cut before winding into several material webs 2.1, then laterally around the shell of one of the two support rollers 3, 4 around or by the gap formed between the two support rollers 3, 4 in the winding bed 5 are guided, where they are wound onto the aligned winding cores 6 to winding rollers 7.
  • the partial material webs 2.1 are guided around the outer shell of the non-driven carrier roll 3 and then wound onto the winding tubes 6 to form winding rolls 7.
  • the support roller formed as a drive roller 4 comprises a revolving and rotatable roller shell 8 and a roller shell 8 axially passing through and fixedly formed roller axis 9.
  • it has an inner, between the roll shell 8 and the roll axis. 9 arranged, a stator 11 and a rotor 12 having drive motor 10, the windings 13.1, 13.2 are energized asymmetrically such that a radial force F (arrow) is generated.
  • F radial force
  • the roller shaft 9 forms the stator 11 and the roll shell 8, the rotor 12 of the drive motor 10.
  • the drive motor 10 itself is designed as a synchronous motor with a high number of pole pairs, a value in the range of 4 to 12, preferably 4 to 8 accepts.
  • the respective drive motor 10 has a direction of action W (arrow), which is directed towards the winding rollers 7 lying in the winding bed 5 and which in an angular range ⁇ of 10 to 60 °, preferably from 20 to 40 ° to the vertical V (double arrow) is aligned.

  • the effective directions W (arrow) of several drive motors 10 can be rectified or approximately rectified as shown, or they can alternatively be oriented in an angular range ⁇ of 5 to 20 ° to the mean effective direction W (arrow).
  • a machine-wide load roller 14 is additionally provided, which rests on the upper side of the winding rollers 7 and which is mounted on at least one adjustable damping device 15 on a loading roller cross member 16. She presses the bobbins 7 in the winding bed. 5
  • the loading roller 14 is arranged either only at the beginning of the winding process perpendicularly or substantially vertically above the winding rollers 7 and reaches after complete winding of the winding rollers 7 an inclined position or, as shown, further arranged vertically or substantially vertically above the winding rollers 7.
