Definitions

  • the invention relates to a thread delivery device with the features of the preamble of the claim 1, especially for the supply of elastic and non-elastic (hard) threads, tapes, strands and the like.
  • Thread delivery devices have in knitting and knitting machines the task of matching the appropriate knitting points each time the right time with the required Supply voltage and in the desired amount.
  • the constancy of the thread tension essentially determines the Uniformity of the knitted fabric obtained. Fluctuations the tension of the fed thread, in particular if they systematically stitch stitch by stitch recurring, to a significant impairment the quality of the knitted fabric. Thread tension fluctuations can temporally abruptly changing thread requirements occur. This is for example in the case of flat knitting machines when the direction is reversed of the thread guide for a short time no thread consumption is present. If the thread tension fluctuates here, there are others at the edges of the knitted fabric Mesh sizes than in the middle.
  • the thread tension is particularly dependent on hard yarns because of the lack of elasticity of the thread from the thread delivery quantity, which corresponds to the respective current If possible, match the time with the thread consumption should.
  • the yarn delivery device known from DE 36 27 731 C1 developed one by one Has stepper motor driven thread wheel. This leads the over a thread brake from a thread spool pulled thread to the relevant knitting points.
  • the thread delivered by the thread wheel runs through a end eyelet of another end pivotally mounted Lever.
  • the eyelet represents a deflection point at which the Thread is diverted at an acute angle.
  • the swivel lever is a constant thread tension by means of a DC motor with a constant Torque applied.
  • the swivel lever connected to a position transmitter, the Detected swivel position and the stepper motor accordingly readjusted.
  • the swivel lever serves in cooperation with the sensor device for detecting the existing thread tension.
  • a controller compares the position of the swivel lever with a setpoint and accelerates or decelerates the Motor if the setpoint is exceeded or not reached. To compensate for sudden changes in demand, which the motor due to its moment of inertia the swivel jack cannot follow immediately a thread store that has a limited thread length can cache.
  • DE 42 06 607 A1 describes a thread delivery device for simultaneous feeding of two threads to a knitting machine known in which a thread delivery wheel of one Disk motor is driven. At least one Thread runs from the thread delivery wheel through the longitudinal opening a conical or trumpet-shaped coil spring. At one end the coil spring can be pivoted holding bearings are a permanent magnet and a Hall sensor provided to deflect the coil spring to be able to record. Based on this, the disc rotor motor readjusted so that in stationary condition stood the target position of the coil spring. In this runs the thread laterally on the inner wall of the Coil spring attached through its opening.
  • the coil spring serves as a spring and damping element, the one certain intermediate storage of delivered thread allowed.
  • WO 90/09625 describes a weaving machine for multi-color weaving known, the so-called for different threads Has storage facilities.
  • the storage operators each have a storage drum, if possible is continuously supplied with thread to it to fill.
  • the weaving machine pulls according to its current Consumption thread from the storage drum.

  • From DE-A-1585166 is a thread delivery device known for circular knitting machines, where a thread delivery wheel from a stepper motor in sync with the knitting machine is driven. To do this is the needle cylinder of the knitting machine connected to an alternator that drives the synchronous motor.
  • the stepper motor can be controlled by program Change the thread feed, e.g. through the chain shifting device or a jacquard device to be controlled.
  • a detection or regulation of the thread tension does not occur, so that the thread tension corresponds to the delivery and consumption ratios accordingly uncontrolled sets.
  • US-PS 38 58 416 is a thread delivery device known for knitting machines with im substantially constant thread consumption and for feeding of hard yarn is provided.
  • the thread delivery device shows one in its speed over the applied voltage controllable electric motor, which by means of a appropriate thread wheel pulls yarn from a bobbin and a thread tension sensor of the respective Feeds knitting site.
  • the electric motor and the Knitting machine speed sensors available at a corresponding other switch position of the switch connected to the setpoint and actual value input of the controller can be.
  • the switch allows the Switching from an operating mode with a constant regulated Thread tension in an operating mode with a defined thread delivery quantity. Every knitting point on the circular knitting machine a corresponding thread delivery device is assigned, so that the amount of thread to be supplied is only the thread consumption corresponds to a knitting point. The thread speed is accordingly low.
  • the thread delivery device is a feeder educated. This has an electric motor driven thread wheel, which is arranged in the thread path and wrapped around it several times.

  • the signal can, for example difference between the setpoint generated in the controller input and actual value of the thread tension are applied.
  • the connection can be added or Subtraction from the difference generated or by other operations are performed.
  • Another possibility lies in the signal before the difference is formed of setpoint and actual value either with the setpoint or with to link the actual value. In all cases it is achieved that at the input of the actual controller a size pending, which consists of the setpoint, actual value and the additional Signal is generated.
  • the information may suffice about the future thread requirement only on the immediate to limit upcoming thread requirements.

  • the controller then temporarily works as a controller.
  • the additional signal can be in a simple Variant be a signal that only provides information about the contains imminent thread requirements. Such can be achieved with a binary signal that is in a fixed time interval before the occurrence of Thread requirement changes its value. Based on this signal the drive motor for the thread wheel can start prematurely or be stopped.
  • a setpoint profile can be specified, which corresponds to the expected Control deviations from the desired thread tension overlaid.
  • Setpoint profile formed by a thread tension setpoint, that of flat knitting machines for the back and forth Return of the thread guide assumes different values.
