Definitions

  • the invention relates to a winding machine for winding a material web, in particular a paper or board web, on at least one winding tube to a winding roll to which a roller mounted in a roller bearing during winding.
  • a material web for example in the form of a paper web, is produced in a relatively large width of currently up to 12 m and virtually endless. In order to be usable for a later consumer, the web must be divided into narrower webs. These narrower webs of material must then be wound into bobbins. For this purpose, a winding machine is used.
  • winding machines which are also referred to as "reel winder” or “slitter” occur in operation problems due to strong vibrations, the result of poor windings, heavy use of the machine and the foundations, reduction in production speed or roller swings to roll ejection.
  • Occurring vibrations with concomitant out of roundness of the winding roll can be associated with the processing of certain types of material webs.
  • the friction behavior or the material web thickness represent relevant variables.
  • the bobbins are decelerated to a standstill. If the rotational frequency of the winding roll passes through the natural frequency of the oscillation of the entire system, then a roll swings can occur. The winding roll vibrates, which can lead to a role ejection.
  • Vibrations occurring during the winding process are classified into two problem areas, namely roll hum and roll swings.
  • the roller humming is a contact vibration between the winding roller and the roller or the rollers, wherein when using several rollers, on which the winding roller is applied, the rollers can oscillate against each other. Roller rumbling may occur when a harmonic of the rotational frequency of the winding roll or winding rolls (when several winding rolls are wound simultaneously) is in the range of the natural frequency of the contact vibration.
  • Due to the roller hum may cause a non-uniform structure of the web in the winding roll, which in turn can increase the contact vibrations.
  • roller bearing is connected via a damping means with a support having a cylinder and a arranged therein piston, which divides the cylinder into two filled with an ERF fluid pressure chambers, wherein the piston with the roller bearings and the cylinder with the support is in communication and wherein the two pressure chambers via a connecting path containing at least one ERF unit , are connected.
  • ERF unit with a special ERF fluid when using the so-called ERF effect is also distinguished by the highest dynamics and wear-free components.
  • the ERF effect leads to a change in the viscosity of the ERF fluid.
  • the viscosity change is continuous, reversible and very fast.
  • a suitable design of the ERF unit can be controlled with this effect, a hydraulic flow.
  • the ERF fluids available today are silicone oil in which polyurethane particles are dispersed.
  • the flow properties of ERF fluids can be varied steplessly and reversibly under the influence of an electric field.
  • the ERF unit preferably has an operating voltage in the range from 1 to 10 kV, preferably from 2 to 6 kV, and a very low operating power. As a result, the operating costs of an ERF unit when used properly within reasonable limits. As the operating voltage or field strength at the ERF unit increases, the apparent viscosity of the ERF fluid in the electric field increases and the volume flow decreases. At a sufficiently high operating voltage, the compressive forces at the gap entrance balance the thrust forces of the ERF effect between the actuator wall and the ERF fluid. The volume flow is then 0, the ERF actuator is disabled.
  • the ERF unit can preferably be realized in a flat-gap or annular gap design with a respective gap width in the range from 0.3 to 3.0 mm, preferably from 0.5 to 2.0 mm.
  • this gap width and the gap length is an essential feature of the already mentioned properties of an ERF unit.
  • the ERF unit can also be in an integral or differential construction be executed.
  • the ERF valves are installed in the housing of the ERF actuator. In this case, it may be necessary to divide one ERF valve into several parallel annular gaps in order to meet the requirements of the design and the necessary volume flows.
  • the differential design divides the ERF valve and the ERF actuator into individual components.
  • the ERF valves can be mounted directly on the cylinder or separated and, for example, hydraulically connected via tubes. However, this is not recommended for highly dynamic ERF units, as part of the optimum performance is lost due to the additional liquid volumes and hydraulic capacities.
  • the ERF fluid preferably has a viscosity in the range of 110 to 10 6 mPas at 20 ° C.
  • the two pressure chambers of the cylinder are additionally connected to each other by a pressure equalizing throttle.
  • a pressure equalizing throttle avoids a jerk of the roller and allows a static pressure equalization, which may be necessary, for example, due to the growing weight of the wound roll.
  • the pressure compensating throttle is preferably arranged in the piston of the cylinder.
  • the pressure compensating throttle can be kept very small, so that no additional space is required outside of the damping means. Leaks that may occur when connecting the pressure compensation throttle can be reliably avoided.
  • a switching valve is arranged in the connecting path, with which the connection path can be interrupted.
  • the switching valve when actuated, may block the flow of ERF fluid from one pressure space to another through the communication path.
  • the piston is clamped between the two pressure chambers, so that a "hard” storage of the roller results. If it should therefore come to the damped operation, in which the piston ERF fluid between the two pressure chambers back and forth, so the basic mode of operation, the reel winding to self-excited vibrations, then the bearing stiffness of the roller by interrupting the connection path between the two Cylinder chambers are changed very quickly.
  • the piston in both pressure chambers preferably equal in size pressure application surfaces.
  • the equally large pressure application surfaces can be produced, for example, by providing the piston not only on one side but on both sides with a piston rod and leaving the piston rod not connected to the roll support unused, for example, leading into a blind bore in the cylinder, which is sealed ,
  • the two pressure chambers are further connected in a preferred embodiment with a circulation flow generating device.
  • a circulation flow generating device With the aid of the circulation flow generating device, a permanent stream of ERF fluid can be generated by the two pressure chambers, at least if the connection path is still permeable or if each pressure chamber is separately connected to the circulation flow generating device. This can be achieved over time constant damping properties.
  • the circulation flow generating device has a tempering device.
  • the flow resistance of the ERF fluid is dependent inter alia on the viscosity and thus on the temperature of the ERF fluid. If the temperature of the ERF fluid is always kept at a largely constant value, then constant or similar damping properties are always present during operation, irrespective of whether the roll winding device is running for a short time or has already been in operation for some time.
  • the roller bearing can be connected via a spring with the support.
  • a spring seems at first unrealistic because it promotes the tendency of the roller to vibrate. But since the damping means is present, you can reliably prevent the swinging of the roller in certain frequency ranges by a combination of damping means and spring.
  • the spring is moreover preferably arranged parallel to the damping means, since this gives an ideal action of any forces.
  • the spring is formed by a spring rocker. Such a spring is relatively stiff. It is practically integrally connected to a machine frame, so that basically no further maintenance is necessary here.
  • roller bearing may also be mounted on an articulated arm, which is supported by a spring element on the support. In this case, the same effect results.
  • roller bearings which are each connected via a damping means with the support, wherein a control device is provided, the vibration-dependent, the permeability of the connecting path of an ERF unit or the other ERF unit or both ERF Units changed.
  • FIG. 1 shows a schematic representation of a winding machine 1, which is designed in the present embodiment as a carrier roll winding machine.
  • the winding machine 1 accordingly has two support rollers 2, 3, which form a winding bed 4 between them, in which a winding roller 5 is arranged.
  • the winding roll 5 is shown here with diameters of different sizes in order to make the progress, ie the diameter increase, visible during winding.
  • winding rolls 5 can be arranged axially one behind the other in the winding bed 4, viewed in the axial direction of the two support rolls 2, 3.
  • the individual winding rollers 5 are expediently then distributed on both sides of the corresponding roller.
  • such a winding machine 1 is also provided with a longitudinal cutting device which divides the tapered material web into a plurality of mutually parallel partial webs.
  • the partial webs may have a width in the range of about 0.3 to 4.8 m.
  • a winding machine such as a support roller, which is also referred to as a rider or load roller, or drive motors for the support rollers 2, 3 are not shown here.
  • the two support rollers 2, 3 are rotatably mounted in roller bearings 6, 7. Of course, a corresponding arrangement is provided with roller bearings at the other axial end of the two support rollers 2, 3.
  • the roller bearing 6 is mounted on a spring rocker 8 and the roller bearing 7 is mounted on a spring rocker 9.
  • the two spring wings 8, 9 are connected to a machine frame (support) 10. They form relatively stiff springs on which the roller bearings 6, 7 are supported.
  • an articulated arm which is hinged to the machine frame 10, wherein the articulated arm is then supported on the machine frame 10 via a spring, for example a helical spring.
  • damping means 11, 12 are arranged in each case. Both damping means 11, 12 are connected to a control device 13.
  • the control device 13 is connected to vibration sensors 14, 15 which each detect a vibration of the roller bearing 6 or 7.
  • the roller bearing 6 is connected via the damping means 11 with a support 10, each having a cylinder 16 and a piston 17 disposed therein, the corresponding cylinder 16 in two filled with an ERF fluid F pressure chambers, in a first pressure chamber 18 and in a second pressure chamber 19 divided.
  • the piston 17 is connected via a piston rod 20 with the spring rocker 8, so the roller bearing 6.
  • a second piston rod 21 is arranged, which has the same diameter as the corresponding first piston rod 20.
  • the second piston rod 21 is guided in a blind bore 22 in an end face 23 of the cylinder 16, which faces the machine frame 10.
  • the two pressure application surfaces on the piston 17 are the same size.
  • seals 24, 25, 26 shown which seal the two pressure chambers 18, 19 to each other or to the outside.
  • the two pressure chambers 18, 19 are connected via a connecting path 27, the at least one ERF unit 28; 28.1 to 28.4 connected.
  • a switching valve 29 ( Figures 2 and 3) is arranged in the connecting section 27, which can be actuated via an input 30 from the above-mentioned control device 13.
  • a pressure compensating throttle 31 is arranged, whose flow resistance is substantially greater than the flow resistance of the at least one ERF unit 28; 28.1 to 28.4. It should be so large that at higher frequencies in the order of 30 Hz, the volume of the ERF fluid F in the two pressure chambers 18, 19 is clamped, so to speak, when the switching valve 29 is closed. Incidentally, the pressure compensation throttle 31 should only let through a comparatively small proportion of the ERF fluid F, which is displaced from one pressure chamber 18 to the other pressure chamber 19 or vice versa. The pressure compensation throttle 31 is used to allow a pressure equalization between the two pressure chambers 18, 19 when the switching valve 29 is closed, when the weight of the winding roll 5 increases.
  • the two pressure chambers 18, 19 are connected to a circulation flow generating device 32.
  • the circulation flow generating device 32 has a pump 33, which removes the ERF fluid F from a tank 34 and pumps it back into the tank 34 through the two pressure chambers 18, 19.
  • a tempering device 35 can be provided, which keeps the ERF fluid F at a temperature which is as constant as possible. This is advantageous in order to keep the damping properties of the damping means 11 constant over a longer period of time.
  • the damping depends inter alia on the resistance of the ERF fluid F in the ERF unit 28; Sees 28.1 to 28.4 exposed. This flow resistance in turn depends on the viscosity ⁇ of the ERF fluid F and thus on the temperature of the ERF fluid F.
  • the ERF fluid F generally has a viscosity ⁇ in the range of 110 to 10 6 mPas at 20 ° C.
  • each pressure chamber 18, 19 with its own connection for both the inflow and for the outflow of hydraulic fluid provided, so that a flow can be ensured even if the switching valve 29 is closed.
  • the damping means 11 operates in a first embodiment shown in FIG. 2 as follows:
  • the two pressure chambers 18, 19 are connected to each other via the open switching valve 29 and the ERF unit 28.
  • the ERF fluid F with a viscosity ⁇ is pumped back and forth via the ERF unit 28 from one pressure chamber 18, 19 to the other pressure chamber 19, 18.
  • the ERF unit 28 operated by the control device 13 has operating voltage V in the range from 1 to 10 kV, preferably from 2 to 6 kV, and a very low operating power P.
  • the ERF unit 28 is realized in a flat-gap or annular gap design, wherein the gap width assumes a value in the range of 0.3 to 3.0 mm, preferably 0.5 to 2.0 mm.
  • the ERF unit 28 is generally implemented in an integral or differential construction, both of which are well known to those skilled in the art.
  • the pressure compensation throttle 31 In order to avoid a jolt of the support rollers 2, 3 due to a pressure difference in the two pressure chambers 18, 19 in a possible switching back to the muted operating mode, ie when opening the connecting path 27, the pressure compensation throttle 31.
  • the pressure compensation throttle is in the long-term range a static Pressure equalization due to the growing weight of the winding roll 5 ( Figure 1) instead.
  • the pressure compensation throttle 31 must be dimensioned so narrow that the momentarily moving volume of the ERF fluid F in the frequency range of 30 to 40 Hz in the pressure chambers 18, 19 acts in a dynamic manner as firmly clamped. This is usually the case when the acceleration forces, which are necessary for conveying the ERF fluid F through the connecting path 27, are substantially greater than the frictional forces which are necessary for the passage of the pressure compensation throttle 31.
  • a total of four ERF units 28.1 to 28.4 are provided for the EFR fluid F with a viscosity ⁇ in the connecting path 27.
  • a so-called full bridge circuit can be formed, which corresponds to the function of a usual in the vibration test 4/3-way valve.
  • the realization of the switching valve 29 and the associated input 30 can also be dispensed with.
  • Such a damping means 11, 12 ( Figure 1) has basically integrated all the necessary elements, that is, you do not require a complex external wiring with a pressure control loop or a pressure accumulator.
  • a winding machine 1 ( Figure 1) is relatively low maintenance and allows safe operation.
