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 winding device of the type mentioned that the roller bearing is connected via a damping means with a support having a cylinder and a piston disposed therein, which divides the cylinder into two pressure chambers, wherein the piston with the roller bearings and the cylinder communicates with the support.
  • the two pressure chambers of the damping means are preferably filled with at least one fluid whose viscosity is variable.
  • the at least one fluid may be an electrorheological or magnetorheological oil, which preferably has a viscosity in the range of 110 to 10 6 mPa s at 20 ° C.
  • the described adjustability of the damping forces is particularly simple and inexpensive given when the damping means is at least partially surrounded by a device which causes a change in the viscosity of the at least one fluid contained in the damping means when acted upon.
  • the device may comprise at least one electrical coil surrounding the damping means at least in regions.
  • the regional environment of the damping means extends along its longitudinal axis, wherein both a single area as well as several, preferably smaller areas may be surrounded by the device.
  • the two pressure chambers 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 arranged in the piston.
  • 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.
  • 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 to the support, wherein a control device is provided which varies the viscosity of the oscillating vibration of the at least one fluid of the one damping means or the other damping means or both damping means.
  • a control device which varies the viscosity of the oscillating vibration of the at least one fluid of the one damping means or the other damping means or both damping means.
  • FIG. 1 It shows the single figure is 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 rollers 5 can be arranged axially one behind the other in the winding bed 4 in the axial direction of the two support rollers 2, 3 seen. Be with a support or contact roller winder Expediently, the individual winding rollers 5 are 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 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 is 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, each having a vibration of the Roller bearing 6 and 7 detect.
  • the respective roller bearing 6, 7 is connected via the respective damping means 11, 12 with a support 10, each having a cylinder 16, 17 and a piston 18, 19 disposed therein, the corresponding cylinder 16, 17 in two pressure chambers 16.1, 16.2 ; 17.1, 17.2 divided.
  • Each piston 18, 19 is connected via a first piston rod 20, 21 with the spring wings 8, 9, so the roller bearings 6, 7, connected.
  • the respective second piston rod 22, 23 is guided into a respective blind bore 24, 25 in an end face 26, 27 of the corresponding cylinder 16, 17, which faces the machine frame 10.
  • the two pressure chambers 16.1, 16.2; 17.1, 17.2 of the respective damping means 11, 12 are filled with at least one fluid 28 whose viscosity ⁇ is variable.
  • the at least one fluid 28 is an electrorheological oil 29 having a viscosity ⁇ in the range of 110 to 10 6 mPa s at 20 ° C, it may be in a further embodiment, however, a magnetorheological oil having preferably the same properties.
  • the respective damping means 16, 17 is at least partially surrounded by a corresponding device 30, 31, which causes a change in the viscosity ⁇ of the at least one contained in the damping means 11, 12 fluid 28 when acted upon.
  • the illustrated device 30, 31 comprises at least one electrical coil 32, 33, which surrounds the associated damping means 11, 12 at least partially.
  • the two pressure chambers 16.1, 16.2; 17.1, 17.2 of each damping means 11, 12 are additionally by a respective; a flow-compensating pressure-compensating throttle 34, 35 connected to each other, wherein the pressure-compensating throttles 34, 35 are arranged in the piston 18, 19.
  • the corresponding flow resistance should be so great that at higher frequencies in the order of 30 Hz or more, the volume of the fluid 28 in the two associated pressure chambers 16.1, 16.2; 17.1, 17.2 is clamped, so to speak.
  • the circulation flow generating device has a pump, which removes the fluid from a tank and pumps through the two pressure chambers back into the tank. Between the tank and the pump can still be provided a tempering, which keeps the fluid at a constant temperature as possible. This is advantageous in order to keep the damping properties of the damping agent constant over a longer period of time.
  • the springs 8, 9 are arranged parallel to the associated damping means 11, 12.
  • Such a damping means 11, 12 has basically integrated all the necessary elements, that is, one does not require a complex external wiring with a pressure control circuit or a pressure accumulator.
