Definitions

  • the invention relates to a winding machine and a method for Winding a continuously running thread on a Coil with the specified in the preambles of claims 1 and 7 Characteristics.
  • a winding machine of this type is known from EP-A-0 374 536.
  • the contact roller used is on a rocker can be swiveled or moved in a straight line stored.
  • a sensor is provided that detects the movement of the Contact roller relative to the surface of the in Operation located coil spindle detecting coil.
  • the Sensor belongs to a control device and works as Two-point control element. If the contact roller from which at Winding process increasing the diameter of the bobbin when stationary Axis of the drum over the dimension set on the sensor is then moved, a control pulse is applied to the rotary drive of the Given drum and the drum rotated so that the Contact roller again moved in the other direction and the falls below the set trigger point on the control element. This stops the drum drive.
  • the older PCT application according to WO-A-96/01222 looks just like that generic document a control device for the Rotary drive of the drum or the winding turret, the discontinuous is gradually rotated.
  • the the coil load-bearing winding spindle should have a determined on its turning circle Assume angular position. This means that an angular position was determined, which is then taken up by the winding spindle, so that the winding spindle at least briefly determined one Maintains position and the drum gradually, so not continuously rotated by fixed angular amounts.
  • the invention has for its object a further winding machine to provide the type described above, the is inexpensive to manufacture and easy to maintain, and moreover has a small size. Furthermore, a winding process should be specified at which the laying accuracy the thread on the bobbin is improved and the contact pressure between the contact roller and the spool a more uniform Has history.
  • this is the case at the beginning of a winding machine described type achieved in that for the continuous Rotation of the drum during the winding trip a control device it is provided that the winding machine a device for Determine the speed of the thread and set up to determine the speed of the winding spindle in operation and that the control device has a computing unit to calculate the respective current diameter of the formed on the bobbin in operation and the current angular velocity between the Beginning and end of each computing cycle as control variables for a continuous rotation of the drum over the whole Has winding trip.
  • the invention is based on the idea that instead of the known control device to provide a control device to thus the rotation of the drum in a quasi-constant sequence of movements to regulate.
  • This can be designed so that, for. B. a computing cycle runs every 10 ms, which is followed by a Control cycle follows. Between the beginning and the end of a each calculation cycle becomes a controlled variable for the rotation of the Drum formed, which replaces the previous control variable and in turn in the subsequent computing cycle from a newly formed one Controlled variable is replaced.
  • the winding machine for the regulation no requires additional elements, such as sensors or the like, but already existing elements that are used to control the Thread tension on the winding machine are used.
  • So is a device for determining the speed of the Fadens and on a device for determining the speed of the in use.
  • About the Computing unit which can be part of the control device, is calculated from the thread speed and the speed of the in Operating winding spindle the current diameter the coil formed and the respective current angular velocity between the beginning and the end of each computing cycle. With this current Angular velocity the drum is rotated further. Doing so from the calculation of the respective current diameter respective setpoint of the angle of rotation for the drum is determined. From the measured period of time between the beginning and the The end of each computing cycle and the respective one The current angular velocity becomes the setpoint of the angle of rotation calculated with which the drum is rotated further.
  • the contact roller can be designed and arranged completely freely. For example it is possible to apply such contact pressure via the contact roller to exercise the scope of the coil forming, which according to the Scheme is designed independent criteria, and for example has a steady course. Here's an example also a steady decrease in the contact pressure without fluctuations possible, which has a favorable effect on the coil structure.
  • a microprocessor can be provided as the computing unit. On such a microprocessor is a suitable unit for Realization of the computing unit. In it can be the most varied desired operations and steps summarized be how u. a. also for thread tension control required are.
  • the device for determining the speed of the thread can be a device for detecting the speed of the contact roller exhibit. Because the diameter of the contact roller and the Run-up angle, in which the thread on the circumference of the contact roller is slanted, are known, can be derived from easily calculate the speed of the thread. It can also any other device for determining the Speed of the thread can be used, for example a separate facility upstream of the laying facility or is arranged elsewhere.

  • the computing unit can have a memory for holding a Table of values for the setpoint of the rotation angle of the drum in Depending on the diameter of the coil. It understands that such a table of values, depending on the application, can be entered. But it is also possible to use the computing unit to be designed so that the setpoint of the angle of rotation in Depending on the diameter of the coil is calculated. Here the computing cycle will then take a little longer. In Considering the mechanical parts of the winding machine however, this has no adverse consequences.

  • changing angular velocities come successively for use, d. H. from an angular velocity out the rotary drive of the drum in one other angular speed switched so that definitely the drum makes a continuous movement, the Course of changing angular velocities a hyperbolic Has character.
  • Computation cycles which are in use can advantageously be used over the winding travel constant time intervals, for example especially in 10 msec.
  • the repetition of the Computation cycles in such short time intervals is quite possible. But it is not harmful if the number of Calculation cycles reduced and the time intervals increased be because the drive of the drum anyway a lot contains mechanical elements that prove to be comparative prove sluggish. It is also possible to have different numbers of computing cycles on the one hand and control cycles on the other, To form averages or the like. In general however, this is not necessary.
