Definitions

  • the invention relates to a reel winding apparatus having at least one roller on which a winding roller bears during winding, a vibration sensor arrangement which determines a vibration of the roller, a control device and at least one actuator, with which the roller is displaceable.
  • the invention relates to a method for winding a material web to a winding roll, wherein the winding roll rests against a roll and the roll is displaced in response to measured vibrations.
  • Such a reel winding device and such a method are for example out EP 1 260 470 B1 known.
  • the winding roll during winding is in a winding bed, which is formed by two support rollers.
  • the material web runs over a stationarily arranged carrier roll.
  • the other support roller is displaceable by an adjusting device which acts on the bearings of the support roller.
  • a vibration sensor is attached on the adjusting device.
  • both support rollers can be displaced. With such a configuration, it would be desirable to achieve that the overall system of the two carrier rollers and the winding roller vibrates less than without these measures.
  • the invention has for its object to keep vibrations small.
  • the speed measuring device preferably has a speed sensor, which determines the speed of a material web running onto the winding roller, and a diameter measuring device.
  • the speed of the web can be determined relatively easily.
  • the diameter of the winding roll can also be determined with a reasonable effort, so that the speed and the diameter of the speed can be easily calculated.
  • the speed is thus available even with such bobbins whose front pages are not available are readily accessible. These are, for example, bobbins, which are located in a Doppeltragwalzenwickler between two other bobbins.
  • the winding roller has a winding core with a front-side marking and the speed measuring device cooperates with the marking. You can limit the mark on the front side of the hub, so does not need to engage in the winding roll.
  • the marking may be formed optically or mechanically. It allows a speed determination in a simple way.
  • the vibration sensor arrangement has at least one sensor which is arranged inside the roller or on a roller cover.
  • the arranged within the roller or on a roller cover sensor makes all movements of the roller directly with. However, it is not disturbed by the material web, so that, for example, an outline of the material web does not pose any danger to the sensor.
  • the senor is designed as an acceleration sensor. With the signal of the acceleration sensor, the necessary information about the vibration movement is readily available. Expediently, a pair of mutually perpendicular, co-rotating acceleration transducers with telemetric transmission of the measured values will be used. The arrangement of such accelerometers within the roller also results in a decoupling of the roller movement for the driving movement of the adjusting device.
  • the roller is designed as an inlet-side support roller of a support roller winder.
  • the inlet or inlet-side support roller is the support roller with which the material web first comes into contact.
  • the information about the current winding state can already be obtained, which possibly changes as a result of the material web flowing in. So you can react relatively quickly to phenomena that could otherwise cause a vibration.
  • a second support roller which also has a vibration sensor arrangement and / or an actuator.
  • One can thus attack on both support rollers to achieve a reduction of the vibrations.
  • a center detection device which detects a winding center of the winding roll. This makes it possible to determine the winding compression of the winding roll with high accuracy. If vibrations occur, then usually swings not only the roll on which the winding roll, but also the winding roll itself. On the roll can be a "countermovement" imprint, so that you can calm down the roll itself. But this is not necessarily a reassurance associated with the winding roll. Accordingly, vibrations may continue to occur. On the winding roll itself but you often have no access. This is especially true for bobbins that lie in the winding bed of a Doppeltragwalzenwicklers.
  • the roller taking into account the movement of the winding roll, so that the entire system of winding roll and roller undergoes reassurance. This can for example reduce a vibration resulting from a non-uniform course of the winding compression results.
  • the loading angle of the contact points between the winding roll and the rollers can be determined from the position of the winding center and the diameter. From the measured movements of the rolls and the measured movement of the winding center can now be calculated with the time-varying angular relationships, the winding compressions in the loading direction at the contact points of the rollers.
  • the center detection device it is preferable for the center detection device to have an encoder designed in particular as an acceleration sensor, which is inserted into the winding roller.
  • an encoder designed in particular as an acceleration sensor, which is inserted into the winding roller.
  • This is usually possible in a simple manner, because the winding roll is formed on a roll core, which is designed as a sleeve made of cardboard or other material.
  • an encoder can be easily installed in the hollow cylindrical interior. The encoder is able to determine the accelerations experienced by the winding roll during winding due to vibrations. From these accelerations, the current position of the winding roll can be determined, it depends less on the absolute position of the winding axis, which shifts with increasing diameter of the winding roll, but on the short-term changes indicating the vibrations or vibrations.
  • the encoder is designed as a guide head. Even with a Doppeltragwalzenwickler the bobbins, which are arranged at the two axial ends, often provided with such a guide head. From the position of the guide heads then determine the winding center. It can be assumed in a first approximation that moves the winding center for all bobbins similar.
  • the invention is achieved in a method of the type mentioned above in that it determines the vibration directly to the roller and determines the speed of the winding roll, wherein the roller is displaced with at least one frequency that matches a winding harmonics.
  • a sensor is preferably used which is arranged inside the roller or on roller covers. Such a sensor is not disturbed by the material web. It also makes it possible to determine the oscillation movement of the roller directly, thus avoiding measurement errors that could arise, for example, due to a clearance within a bearing.
  • a Doppeltragwalzenwickler Preferably used for winding a Doppeltragwalzenwickler and determines the vibrations at least at the inlet side roller.
  • the vibration problem is particularly critical because under unfavorable conditions there is a risk that the winding roll pops out of the winding bed when the vibrations are too strong. If you use the inlet side roller to determine the vibrations, then you capture the vibrations at the earliest possible time, so you can intervene just as early in the formation of the vibration.
  • the axis is the winding center. If the information about the location of the winding center is continuously available, then you not only detects the movement of the roller on which the winding roll, but also the movement of the winding roll itself. One can then control the movement of the roller so that the overall system minimal roll from roller and winding roll. It is expedient to use a sensor or sensor that can detect accelerations.
  • FIG. 1 shows a roll winding device 1, which is designed as a double take-up roll winder.
  • the roll winding device 1 has two support rollers 2, 3, which form a winding bed 4, in which a winding roller 5 is arranged.
  • the winding roll 5 has as core a winding tube 6, on which a material web 7 is wound, which tapers over the inlet-side support roller 2.
  • the material web 7 wraps around the inlet-side support roller 2 and then runs in a nip 8 on the winding roller 5.
  • the two support rollers 2, 3 are driven. However, a drive is not shown in detail for reasons of clarity.
  • a pressure roller 9 is provided to press the winding roller 5 in the winding bed 4.
  • the pressure roller 9 is used to influence the winding hardness of the winding roll 5. Further, it can be used to prevent ejection of the winding roll 5 from the winding bed 4.
  • the two support rollers 2, 3 each have actuators 10, 11, which are shown here for simplicity by arrows.
  • the actuators 10, 11 act on bearing housings 12, 13, in which roll pins 14, 15 are mounted. With the help of the actuators 10, 11, it is possible to shift the support rollers 2, 3. Shown is a shift in the direction of gravity. Other directions of displacement are possible.
  • the support roller 2 has an oscillation sensor arrangement formed by acceleration sensors 16, 17 arranged essentially perpendicular to one another.
  • the support roller 3 is provided with corresponding acceleration sensors 18, 19.
  • the respective acceleration sensors 16, 17 and 18, 19 do not have to be arranged exactly perpendicular to each other. However, they must each have measuring directions which, viewed in the circumferential direction of the respective support roller 2, 3 forms an angle.
  • the acceleration sensors 16-19 are each disposed within the support roller 2, 3. They can also be arranged on an end face of the support roller 2, 3, that is on a roller cover. They rotate with the respective support roller 2, 3 and transmit their signals in each case telemetrically to a control device 20. For this purpose, this control device 20 has receivers 16'-19 '. The control device 20 is thus informed about the current movement of the support roller 2, 3, which result in a vibration.
  • the winding tube 6 is provided on its front side with markings 21, which can be detected by a pickup 22.
  • the pickup 22 is also connected to the controller 20.
  • the control device 20 is thus continuously informed about the current speed of the winding roll 5.
  • the speed measuring device formed by the markings 21 and the sensor 22 it is also possible to provide a sensor 23 which determines the speed of the incoming material web 7 and a sensor 24 which determines the diameter of the winding roller 5.
  • the two sensors 23, 24 are also connected to the control device 20.
  • the sensor 24, for example, scans the position of the pressure roller 9, as shown schematically, to obtain information about the diameter of the winding roll 5. From the diameter of the winding roll 5 and the speed of the material web 7, the speed of the winding roll 5 can be determined.
  • a sensor 25 is provided which determines the current position of the axis of the winding roll 5.
  • the winding roller 5 may have an insert 26 as a donor.
  • a sensor 25 is preferably able to absorb only or accelerations.
  • the control device can then control the actuators 10, 11 with these frequencies and ensure that first the support rollers 2, 3 remain at rest, ie the oscillatory movement of the support rollers 2, 3 caused by the system is superimposed on a corresponding countermovement.
  • This countermovement can be entered via the bearing housing 12, 13 in the support rollers 2, 3.
  • a coupling to the accelerometers 16, 17 and 18, 19 does not take place because these accelerometers 16-19 are decoupled from the actuators 10, 11.
  • This regenerative effect leads to the coincidence of some harmonics of the winding speed with certain natural frequencies of the winding system of support rollers 2, 3, winding roller 5 and pressure roller 9 to a self-energizing process.
  • Most of these are natural frequencies at which the winding roll 5 itself undergoes a large dynamic deformation. This is the case, in particular, in the case of the so-called contact own frequencies, in which the carrier rollers 2, 3 and the winding roller 5 oscillate in an antiphase movement relative to one another.
  • the problem with this design is twofold.
  • the vibration frequencies of the device 1 change continuously, because not only the diameter of the winding roll 5, but also their mass changed.
  • the winding ripple forms on the peripheral surface of the winding roll 5, wherein one has virtually no direct access to the winding roll 5, ie in a normal support roll winder, as shown in the figure, you have virtually no possibilities, a counter-movement in the Winding roll 5 to initiate, so that the winding roller 5 rests.
  • the movements of the support rollers 2, 3 should be detected on both support rollers 2, 3.
  • This measurement can be carried out in each case by the pair of mutually perpendicular, co-rotating accelerometer 16-19 with telemetric transmission of the measured values.
  • a measurement of the oscillatory motion at the position housings 12, 13 of the support rollers 2, 3 is not sufficient here, since for the control of a decoupling of the roller movement to move the actuators 10, 11 is required.
  • the movement of the center of the winding roll 5 is also detected. This can be measured relatively easily for the bobbins on the edge with accelerometers, which are arranged directly on the guide heads (non-axle).
  • the instantaneous geometry of the winding roll 5, which is calculated from the position of the guide heads or the position of the pressure roller 9, the loading angle of the contact points to the support rollers 2, 3 can be determined.
  • the winding rollers 5 arranged in the axial center to provide the insert 26 with a sensor, for example a magnet or the like, so that information about the movement of the winding axis can be obtained via the sensor 25, even if the rollers are arranged centrally.
  • actuators 10, 11 which are integrated in one or both support rollers 2, 3, for example piezoceramic film modules or piezoceramic excited masses.
  • the measurement required to detect the movement of the support rollers 2, 3 can also take place within the support rollers 2, 3. Decoupling is not required here since the manipulated variable is detected directly.
