Definitions

  • the invention relates to a method for winding threads onto a sleeve according to the preamble of patent claim 1.
  • the invention further relates to a device for winding threads onto a sleeve according to the preamble of claim 6.
  • a gap is left free between the bobbin tube and the contact roller to prevent damage to the first layers of threads at the beginning of the bobbin build-up.
  • This gap gradually fills up and the surface of the bobbin pack comes into contact with the contact roller, the speed of which is set according to the desired winding speed of the thread.
  • the speed of the sleeve is successively reduced during the filling of the gap in accordance with a predetermined speed ramp in order to keep the peripheral speed at the coil surface of the coil being built up approximately constant.
  • the present invention has for its object to provide a method and an apparatus for winding a thread on a sleeve, which makes it possible to detect different surface speeds between the bobbin surface and the contact roller and to connect the controller for the correction of the speed of the bobbin.
  • Another object of the invention is to change the ramp of the speed curve of the bobbin during the filling of the gap between the contact roller and the bobbin surface for the following bobbin winding process because of the preceding one.
  • the microswitch which measures the lifting of the contact roller due to the pack building up on the coil, because the triggering of the regulation of the different speeds of the coil surface and the surface of the contact roller after mutual contact by a measurable Operating parameters are carried out.
  • the detuning of the operating parameter can now be used to trigger the regulation of the speed of the coil.
  • the operating speed of the mandrel after touching the contact roller can be used to control the speed of the coil.
  • the contact force of the contact roller on the coil surface or the torques or the power consumption of the drive motors of the contact roller or the coil mandrel can be measured and the controller of the coil mandrel drive activated when the predetermined limit value is reached will.
  • the different surface speeds can be determined at a much earlier point in time than in the known winding machine, since, in order to raise the carriage, a certain contact pressure must be exerted on the contact roller by the coil before the contact roller and the arm supporting it are lifted at all . It is easily possible to determine even very small changes in speed - in the positive and in the negative direction - of the contact roller driven by an asynchronous drive motor, so that, in contrast to the activation of a switch, no switching path has to be covered. By simultaneously measuring the contact force of the contact roller on the coil, it can further be ensured that the control of the speed of the coil or the contact roller only starts when a predetermined minimum value has been reached.
  • reference number 1 shows a high-speed winder for synthetic filaments in particular. To simplify the description, only a single thread run is shown. In reality, up to eight spools are arranged side by side on such machines on each mandrel. The construction of the machine 1 corresponds to the known prior art, as described, for example, in the already mentioned European Patent No. 0200234.
  • the housing of the machine 1 is designated by reference number 3.
  • a turret 5 is pivotable about an axis 7 and carries at both ends a mandrel 9, on each of which a sleeve 11 is attached.
  • the pack 10 of a full spool 13 is shown on the mandrel 9 below; only a very small amount of threads is wound on the upper sleeve 11 and is barely visible in FIG. 1.
  • the thread 15 tapering from above is guided back and forth by a traversing device 17 and, before it reaches the sleeve 11, loops around a contact or contact roller 19. Between the contact roller 19 and the surface of the sleeve 11 in FIGS.
  • a gap "S” is present, which is only filled after a certain amount of thread has been wound onto the sleeve 11 and then disappears.
  • the size of the gap "S” is set in advance and depends on the speed of the contact roller 19 and thus the wind speed of the machine, as well as on the titer and other properties of the thread 15 to be wound.
  • the contact roller 19 and the traversing device 17 are mounted in a cantilever 21 which is vertically displaceable along the guide 23.
  • a force measuring means 20 e.g. a force measuring bearing or a load cell can be installed, with which the contact force of the contact roller on the coil package can be measured and the measured value can be used to activate a controller 31.
  • a device for measuring the contact pressure is known for example from EP-A-0371912.
  • the initial winding of the thread 15 onto the sleeve 11 without contact with the contact roller 19 has the advantage that there is no "flexing" and friction of the contact roller 19 and the sleeve 11 and thus no damage to the outer layers of the threads 15 wound on the sleeve 11 can.
  • the time until the gap "S" is filled is determined using a previously calculated speed ramp, i.e. a speed curve that lowers the speed of the spool mandrel 9 with increasing diameter of the spool pack 13 so that when the gap "S" is filled - and thus mutual contact - the two surface speeds are mathematically identical.
  • a speed ramp i.e. a speed curve that lowers the speed of the spool mandrel 9 with increasing diameter of the spool pack 13
  • the "detuning", ie the change in speed of the contact roller 19 is detected by the controller and the regulation of the drive of the coil mandrel 9 is activated.
  • the speed reduction of the coil mandrel 9 does not continue through the predetermined ramp, but is interrupted immediately after the “detuning” or after a predetermined time and the speed v DO of the coil mandrel 9 is immediately increased.
  • the time span during which the two surfaces in contact with one another have unequal speeds is greatly shortened. As a result, there is no uncontrolled moment arises between the surfaces of the contact roller and the coil package.
  • the time t1 of the detuning and its direction i.e. Spool speed too high or too low in relation to the contact roller speed is immediately detected by the machine control.
  • the amount of the disturbance can also be recorded. If desired, these two values can now also be used together with the already calculated parameters for the "old" speed ramp to determine a new ramp for the following coil structure.
  • the aim of the design of the ramp is to delay the time t 1 of a fault as long as possible.
  • control-related, software-based procedure for changing the speed ramp due to the detuning is illustrated and explained on the basis of a possible “circuit” according to FIG. In practice, this "circuit" is "implemented” in the machine control software.
  • the setpoint generator 25 for the contact roller 19 receives setting values for both the wind speed v TW and a correction factor which effects the control of the peripheral force, as described, for example, in EP-A-182389. Since an asynchronous motor is used as the contact roller drive motor 37, the contact signal (frequency F-tachometer) deviates from the contact setpoint. The absolute level of the frequency (F-tachometer) is of no importance for monitoring in the monitoring device 27. After such a time delay, after which the contact roller 19 runs at the starting speed, the mandrel drive motor 35 is switched on by the control and is also brought up to the starting speed, where the thread feed can take place.
  • the monitoring device 27 switches the ramp generator when the thread is drawn in 39, which delivers its output frequency to the frequency converter 33.
  • the controller 31 is deactivated at this point in time since the contact signal (F-tachometer) cannot be used for regulation.
  • the contact frequency deviates from its starting value. This deviation is determined by the monitoring device 27, which now switches off the ramp generator 39 and activates the controller 31.
  • the controller 31 then returns the mandrel speed v TW to a value which gives a predetermined contact frequency (the control frequency corresponding to the setpoint for the winding speed). If a contact pressure monitor is also installed, the controller 31 is only activated after the set value has been reached.
  • the contact force of the contact roller 19 on the coil surface can itself be used as an operating parameter for triggering the controller 31 (FIG. 9).
  • force measuring elements can also be installed in the bearings of the contact roller.
  • a force measuring device on a contact roller is known for example from US-A-5,033,685.
  • the deviation from the starting value must reach such a degree that an essentially slip-free, non-positive connection is established between the surfaces of the contact roller 19 and the package 10 on the coil 11. Small disturbances can go unnoticed. It is also possible to incorporate a time delay after the deviation has been ascertained, in order to ensure that the requirements for the essentially slip-free, non-positive connection between the surfaces of the contact roller 19 and the coil pack 10 have been met, so that the contact signal is clear Obtain a measured value for the actual winding speed v DO . May be due to a time delay be dispensed with if the contact pressure is monitored.
  • the deviation from the starting value can be upward (FIG. 7) or downward (no figure).
  • the control frequency can be above or below the start frequency or it can be the same as the start frequency.
  • the change (detuning) of the power consumption f of the drives of the contact roller 19 or of the coil mandrel can alternatively be used as operating parameters.
  • the new value of the upset i.e. the time and the measure of the last detuning can be used to calculate the ramp for the next winding process.
  • the detuning of the speed of the mandrel can be detected and used to activate the controller 31.
