Definitions

  • the invention relates to a method for winding a material web to a web roll, in which the web roll is rotated and vibrations are detected, wherein the speed of the web roll is reduced when a vibration exceeds a predetermined strength. Furthermore, the invention relates to a winding device for winding a material web to a material web roll with a roller drive, which is connected to a control device, and a sensor arrangement for detecting vibrations, which is connected to the control device, wherein the control device at a signal of the sensor arrangement, the one indicates critical vibration, reduces the speed of the web roll
  • Paper webs are produced almost endlessly. In order to remain manageable for a consumer later, they are cut to the necessary width in one of the last production steps and wound up shortly thereafter. For this purpose, a roll core or a web roll forming on the roll core is rotated. The roll core pulls on the web yourself. Associated with this is an increase in the diameter. The speeds at which a paper web is wound onto a roll are well in the range of well over 2000 m / min.
  • vibrations can occur during winding. These vibrations can have different causes. Although this is not completely clear, it is believed that at least some of the vibrations are induced by the incoming web. For example, variations in the thickness of the material web can lead to a non-circular web roll. Such vibrations can be amplified in a resonance range, to such an extent that the roll of web material jumps out of the winding device. Such a situation must be reliably avoided, because a winding roll with a mass of several 100 kg and a high speed, which pops out of the winding device, can cause considerable damage.
  • the invention has for its object to achieve high productivity during winding.
  • This object is achieved in a method of the type mentioned fact that after lowering the speed, the feed rate of the material web is increased, wherein the web roll at the beginning of a winding operation with a maximum acceleration drives and upon occurrence of a critical vibration, the rotational frequency of the web roll reduces a predetermined increment.
  • the material web roll is driven at the beginning of a winding process with a maximum acceleration.
  • there are critical vibration ranges in each winding device which correspond to the natural vibrations of the device. If the speed of the winding roll coincides with the critical natural vibration of the winding device, this can lead to oscillation amplitudes. The slower a change in speed of the winding roll takes place in such a speed range, the higher the probability of a high oscillation amplitude.
  • the natural oscillations of a winding device can be determined in advance.
  • a drive for the winding roll must usually be designed so that it can accelerate, for example, after a web break even a relatively large web roll in a predetermined time back to the desired winding speed.
  • the material web drive for the acceleration of the roll core and a winding roll formed thereon is in principle oversized. Now you can take advantage of this power reserve to drive through the winding roller at the beginning of the winding process very quickly through the critical vibration ranges. This has two advantages. On the one hand, the winding time is further shortened. On the other hand, the risk that vibrations can form and swing in the resonance regions is relatively small.
  • the rotational frequency of the web roll is reduced by a predetermined increment. This simplifies the control. The gradual reduction of the rotational frequency allows a good control over how many steps the vibration tendency has been reduced so far that no more critical situations arise.
  • the speed of the web roll is kept constant after reducing the speed.
  • the web roll is briefly decelerated after reaching the maximum speed regardless of the actual occurrence of a vibration. If the acceleration process is optimized to such an extent by utilizing ramps of maximum acceleration that critical oscillation ranges of the winding device are traversed in the shortest possible time, then in the further course of the winding process with then constant feed rate, a coincidence between the critical oscillation range of the winding device and the rotational speed of the winding roller can occur come. By constant increase in diameter of the winding roll slowly reduces the speed of the winding roll. This has the consequence that the winding speed slowly approaches "from above” a critical oscillation range of the Wikkelvorraum, which previously pass through during the acceleration process "from below” quickly has been.
  • the increment is in the range of 1 to 3 Hz. Although this increment is relatively small, it can still be achieved that the winding device leaves a critical state of vibration again.
  • the object is achieved in a winding device of the type mentioned above in that the control device after reducing the speed of the web roll the speed of the material web increases, wherein the control device controls the roller drive at the beginning of a winding process with maximum acceleration and the control device has an incremental encoder, which reduces the rotational speed of the roller drive upon occurrence of a critical vibration in each case by a fixed increment. This largely avoids critical conditions.
  • the speed of the web roll is no longer critical. Nevertheless, the speed of the supplied material web can be increased in order to achieve the fastest possible completion of the web roll.
  • control device controls the roller drive at the beginning of a winding process with maximum acceleration allows critical frequency ranges, which are caused by natural oscillations of the winding device, to pass quickly.
  • critical frequency ranges which are caused by natural oscillations of the winding device, to pass quickly.
  • the mass of the winding roll is still low.
  • the drive still has enough reserve for greater acceleration.
  • the control device has an incremental encoder, which reduces the rotational speed of the roller drive in each case by a fixed increment when a critical oscillation occurs.
  • the control device must therefore, as stated above, can not follow any complicated speed curves. It is controlled with fixed stages, so that it can be constructed as an intelligent controller despite a comparatively simple control algorithm.
  • control device operates after the reduction of the speed of the roller drive at a constant speed.
  • the control device can therefore be relatively simple. It does not have to follow any complicated speed curves. Rather, it is sufficient to produce a constant speed of the material web roll. This is relatively easy for a commercially available controller.
  • control device has a speed detection device and a memory in which a critical speed range is stored, wherein the control device controls the roller drive with maximum acceleration or deceleration at the latest when reaching a limit of the speed range from the outside.
  • a critical speed range or more critical speed ranges are given by natural frequencies in a winding device in the rule. At natural frequencies, small suggestions are often enough to cause the system of winding device and winding roll to vibrate. If the controller determines that it is approaching such a speed range, then it can maximally accelerate or decelerate the winding roll to pass through the speed range from bottom to top (during acceleration) or from top to bottom (during deceleration) in the shortest possible time , The shorter the time in which the winding device is in a critical state, the lower the risk of Aufschwingens.
  • Fig. 1 shows a schematic representation of a winding device 1 for winding a web 2 to a winding roll 3.
  • the winding roll 3 rests in a winding bed 4, which is formed by a first support roller 5 and a second support roller 6.
  • the first support roller 5 has a first drive 7
  • the second support roller 6 has a second drive 8.
  • the two drives 7, 8 are controlled by a control device 9.
  • the control device is connected to a sensor arrangement, which in the present case consists of a first vibration sensor 10 on the first support roller 5, a second vibration sensor 11 on the second support roller 6 and a third vibration sensor 12 on the winding roller 3.
  • the third vibration sensor 12 is coupled, for example, to a clamping head for holding the winding sleeve 13, onto which the material web 2 is wound to form the winding roll 3.
  • the sensor arrangement with the vibration sensors 10-12 is to be understood here only as an example. In many devices, there is also a so-called rider or load roller, which pushes the winding roller 3 in the Wikkelbett 4. Also there, a vibration sensor can be arranged. Under certain circumstances, it is also possible to dispense with one or two vibration sensors if, for example, it is sufficient to determine the vibration only at the winding roller 3.
  • FIG. 2 to 10 show in a corresponding manner respectively the course of the speed n of the winding roll, the increase of the diameter D, the acceleration a, with which the winding roll 3 is accelerated, and the speed v, with which the material web 2 is supplied, over the time t. Furthermore, a frequency range F is shown, which includes critical natural frequencies of the winding device 1.
  • the winding of a web 2 of paper is simulated, which has a basis weight of 80 g / m 2 and a density of 0.7 kg / dm 3 .
  • the outer diameter of the winding tube 13 is 177 mm and the diameter of the finished winding roll 3 is 1300 mm.
  • Fig. 2 shows an ideal course of a winding process, in which the speed v has approximately the shape of a trapezoid.
  • the winding roll 3 is accelerated at an acceleration of 40 m / min / s to 2500 m / min.
  • the critical frequency range F is ignored.
  • Fig. 3 a similar winding course is shown, as it has been realized so far. At three points in time t1, t2, t3, critical vibrations have resulted.
  • the winding roll 3 was decelerated with the maximum possible delay of -40 m / min / s. The speed is reduced accordingly. After each deceleration, the web 2 is fed at a constant but reduced speed.
  • Fig. 4 shows a procedure accordingly Fig. 3 , However, here additionally, the feed rate of the paper web is controlled so that the acceleration phase is interrupted shortly before a critical vibration range of the winding device is achieved.
  • Fig. 5 now shows the procedure according to the invention.
  • the control device 9 resolves the vibration problem "intelligently".
  • the procedure after Fig. 5 is the reaction to the winding course according to Fig. 3 shown.
  • the acceleration a is reduced, for example to 20 m / min / s.
  • the speed n remains approximately constant below the critical frequency range, but the feed rate continues to increase.
  • the critical frequency range is thus bypassed.
  • the winding time is here however by 32 s shorter than at Fig. 4 , which must be used as a basis for comparison.
  • Fig. 7 shows a winding course in which the acceleration acceleration is increased. It is now 50 m / min / s. This is possible because the empty winding tube 13 and the winding roll 3 forming thereon have a comparatively low moment of inertia.
  • the critical frequency range F is traversed fast enough during run-up, so that no additional measures are required. Even when reducing the speed n of the critical frequency range F is traversed fast enough, so that no additional measures are required here.
  • the time savings compared to the procedure Fig. 4 is 44 s. This corresponds to a productivity gain of about 65 tons per day for the paper data mentioned above.
  • the rotational frequency is reduced in each case by a fixed increment, for example 1.5 Hz. This has the advantage that the control can be relatively simple.
  • the maximum load demanded by the drive 7, 8, for which the drive 7, 8 must be designed occurs only in extreme situations, for example, web break, winding and acceleration of large winding rolls in the reeling under maximum web tension. During the normal winding process, therefore, sufficient reserves are available to the drive 7, 8 depending on the current driving situation. These reserves are harnessed by intelligent controller 9 to combat critical vibrations, particularly when winding high friction papers, for example, woodfree uncoated papers, packaging papers, and uncoated cartons.
  • the control device 9 is thus able to change the state of acceleration of the winding roll permanently. This has a certain influence on the train control. Preferably, therefore, the winding roll is controlled so that transitions between the different accelerations are ground as best as possible.
  • the sensor arrangement may comprise sensors which are arranged as acceleration sensors on the centering heads and the Reiterwalzentraverse. It is also possible to arrange acceleration sensors on the support roller bearings. Thus, all components involved directly in the winding process are detected vibration technology and can be evaluated.
