Definitions

  • the invention relates to a method for winding a material web, in particular a paper or board web, in a winding machine on a winding tube to at least one winding roll by means of at least one elastically mounted roller on which the winding roll during winding up or rests.
  • 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 by 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 back-up roll winding machine or laterally on this, or the cores are in one of two support rollers of a double carrier roll winding machine formed winding bed.
  • a back-up roll winding machine either only a single winding roll may be wound or a plurality of winding rolls each held in winding stations by individual tensioning devices, the tensioning devices alternating the winding rolls to both sides from a vertical axis passing through the center of the backing roll hold, wherein the connecting lines between the centers of the bobbins and the support roller are inclined in each case to both sides of the vertical at an acute angle or form a right angle with the vertical.
  • the clamping heads and the winding tubes in the winding stations can also have different diameters.
  • One from the DE-AS 23 18 351 known supporting device is characterized in that in all the essential parts and with respect to the characteristics of the same springs, the spring systems are arranged asymmetrically with respect to the plane passing through the winding roll axis vertical plane. In this way, the two support rollers associated lines of action are at an angle to each other, so that the vibrations also impinge on the respective suspension system in a different angle or at different locations. As a result, the suspension behavior of the suspension systems of the two support rollers is different, without that therefore the support roller suspension or its storage or the support rollers themselves would have to be designed differently or adjustable.
  • Carrier roller bearing with a damper as a locking device in the EP 1 650 148 A a winding machine with a position-locked winding roller is proposed which compensates for the deflection of the roller under the mass of the winding roller changing during winding and thus prevents the associated negative changes in geometry when utilizing the advantages of elastic mounting. Furthermore, in the DE 10 2005 000 052 A1 a position-controlled carrier roll with a variable damper and in the DE 10 2005 024 266 A1 an adjustable 2-chamber damping cylinder proposed in combination with a resilient support roller bearing.
  • a support roller is optimally damped at their bearings when the bearing stiffness c L goes to zero. Then the support roller is mounted on each side only on a hydraulic cylinder in a linear guide or a lever. The hydraulic cylinder initiates the damping forces directly on the roll neck.
  • this procedure is technically very complicated, since the position of the support roller must be kept exactly by a separate position control at each bearing point.
  • the smallest misalignment of a carrier roll has a massive effect on the winding structure of the winding roll.
  • the support rollers are still stored today on mechanically acting spring stiffness, for example on a flexible rocker, as in the above-mentioned DE 10 2005 024 266 A1 is disclosed.
  • a technically sensible compromise between the technically complex position control with mechanically optimal damping on the one hand and a self-adjusting mechanical stiffness roller position - with increasing spring stiffness a decreasing damping capability is connected - thus represents a variable spring stiffness, as provided by the invention.
  • the spring stiffness is controlled as a function of the paper roll weight so that the damping always works almost optimally.
  • c L f m W .
  • c L is the spring stiffness and m W the mass of the winding rolls.
  • the spring effect can be integrated in the bearing of a roller, so that one can speak in this case instead of spring stiffness as well as bearing stiffness.
  • the system comprises an actuator, a spring, in particular with a non-linear spring characteristic, a damper and a measuring device in order to be able to determine the position of the support rollers accurately.
  • spring stiffness of the spring and / or the damping of the damper are variable.
  • springs are used in the form of bending beams or as spiral springs.
  • the damper comprises a damping cylinder, which is filled with an electrorheological or a magnetorheological fluid whose damping is changed by changing an applied electric or magnetic field.
  • the winding machine is developed such that the at least one roller is equipped with a linear guide or another element with which the at least one roller is displaceable in the direction of the other roller.
  • At least one of two rollers is fastened to a rocker, by means of which it is pivotable in the vertical direction or in the direction of the other carrier roller.
  • the rocker is preferably infinitely adjustable in length.
  • the invention also relates to a method for winding a material web, in particular a paper or board web, in a winding machine on a sleeve to a winding roll by means of at least one elastically mounted roller on which the winding roll on winding up or rests.
  • the frequency of the oscillation problem ie the problematic resonance frequency
  • the tracking of the damping characteristic d is controlled as in the case of spring stiffness c L or controlled according to the mass m W of the winding roll. It is sufficient if, for the problem frequency f, a mean value between the second highest contact frequency of the carrier roll and the winding roll and the carrier roll is set without the influence of the paper pulp. In this case, those frequencies are to be understood as meaning the frequencies at which the winding roll beats either in-phase or out-of-phase against the two winding rolls and thereby generates undesirable vibrations.
  • the damping is preferably set to an intermediate value between the bending natural frequency of the roll and the second highest contact natural frequency of the roll to the winding rolls, or the damping is optimized for the strongest oscillation.
  • the damping behavior can be optimized to the strongest of these vibrations.
  • the damper setting is controlled as a function of the occurring problem frequencies ⁇ .
  • the determination of the problem frequencies is carried out by a vibration measurement with subsequent harmonic analysis by Fourier transforms.
  • the entire invention can be used in a double carrier roll winding machine, but also when only a single roller as a support roller for the cut longitudinal paper webs is used.
  • the individual coils are supported alternately in an eleven o'clock or one o'clock position with respect to the support roller.
  • there is a desire for optimal damping of the support roller which is realized by the use of a system according to the invention.
  • the windings can also be located at other symmetrically opposite positions in the region of the two upper quadrants of the support roller.
  • the support rollers 1, 2 form a roller bed, in which several adjacent bobbins 3 rest during winding on the support rollers 1, 2.
  • a longitudinal cutting device (not shown), a material web, in particular a paper or board web, is cut into a plurality of individual webs before winding, which are then passed through the gap between the support rolls 1, 2 or laterally around the jacket of one of the two support rolls 1, 2 are fed into the roll bed, where they are wound up in aligned rows of sleeves 4.
  • the support roller 1 is mounted on a positioning means 6 via a bearing 5, which comprises an actuator 7, a spring 8, a damper 9 and a measuring device 10. This generates according to the current position of the support roller 1, a signal that passes the measuring device 10 to the actuator 7, so that this according to a deviation between an actual position and a required target position of the support roller 1, a piston 11 of a hydraulic or pneumatic cylinder 12 actuated.
  • an electromotive adjusting means such as a pneumatically operated bellows cylinder or a rolling diaphragm can be used.
  • the piston 11 in turn presses on the spring 8, and this acts on the support roller 1 a.
  • the damper 9 is a vibration energy dissipation element and includes, for example, a cylinder 13 filled with a gas.
  • the gas is compressed by a punch 14 connected to the bearing 5. If, as a result of the vibrations of the support roller 1, the bearing 5 passes this to the punch 14, this compresses the gas, and a part of the vibration energy is converted into heat. It is understood that the vibration energy in other ways out of the system can be derived, for example by electrical eddy currents.
  • the support roller 2 is mounted on a bearing 15 which, like the bearing 5 of the support roller 1 is mounted.
  • the spring stiffness of the spring 8 can be changed.
  • a linear guide 16 by which the height position and / or the horizontal position of the bearing 5 and thus the position of the support roller 1 with respect to the support roller 2 and with respect to the winding 3 can be adjusted ,
  • the support roller 2 is mounted on a rocker 17 pivotally mounted about a pivot point 18 in order to change their position with respect to the support roller 1 and the coil 3 can.
  • Fig. 3 comprises the actuator 7 on both sides of the shaft of the support roller 1 as a bending beam 19, 20 formed springs for the elastic mounting of the support roller 1, on the on the bearings 5, 25th
  • Piston 21, 22 of cylinders 23, 24 act.
  • the bending beam 19, 20 press in turn against the bearings 5, 25 of the support rollers 1, 2 and are mounted in brackets 26, 27.
  • the rigidity of the bending beams 19, 20 can be changed by changing the position of the cylinders 23, 24 in the direction of the axes of the bending springs 19, 20.
  • a damper 28, 29 is also provided in each case.
  • a measuring device 30 for determining the position of the support roller 1 is provided.
  • Fig. 4 are the support rollers 1, 2 mounted on positioning means 31, each comprising a hydraulic cylinder 32 and 33, respectively.
  • the cylinder 32 has an oil column 34 whose length is adjustable via a valve 35 from an oil reservoir.
  • Throttles 38, 39 are provided, via which the speed at which the oil or the air can escape from the interior of the cylinder 32 is adjusted.
  • the cylinder 33 is preferably constructed in the same way as illustrated by the example of the cylinder 32.
  • the spring characteristic of the spring 40 with increasing distance s a greater slope; that is, the spring 40 has a non-linear spring characteristic and acts the harder, the greater the distance traveled.
  • a backup roll winding machine ( Fig. 7 ) are shown with a support roller 41, are supported against the two winding rollers 42, 43 respectively in the nine o'clock position and in the three o'clock position.
  • the winding rollers 42, 43 are supported by (not shown here) supporting devices and pressed against the jacket of the support roller 41.
  • the support roller 41 is mounted on a positioning means 45 via a bearing 44, which, like the positioning means 6, comprises an actuator 46, a spring 47, a damper 48 and a measuring device 49.
