Definitions

  • the invention relates to a thread delivery device with the features of the preamble of the claim 1, the supply of elastic 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. This applies particularly to elastomeric yarns or other elastic threads, mainly in combination with hard, i.e. essentially inelastic yarns (basic thread), to more or less elastic knitted fabrics are processed.
  • the tension of the elastomeric yarn determines the grip and shape retention of the produced knitted fabric essentially. Fluctuations in voltage of the supplied elastomeric yarn can, in particular if they systematically stitch stitch by stitch recurring, to a significant impairment the quality of the knitted fabric.
  • Thread delivery device For applications with fluctuating time Thread consumption is that known from DE 36 27 731 C1 Thread delivery device that has been developed by a has a stepper motor driven thread wheel. This leads it from a thread spool via a thread brake pulled thread of the knitting point concerned.
  • the thread delivered by the thread wheel runs through an end-side eyelet of another end pivoted Lever, with the eyelet being a deflection point 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 its pivot position and the stepper motor accordingly readjusted.
  • the swivel lever thus acts as Thread store for temporarily storing thread from has not been removed due to the knitting points the moment of inertia and the control characteristic of the Stepper motor has been delivered however. Also serves he adjusting the thread tension as well as in interaction with the sensor device for detecting the existing Thread supply.
  • This thread delivery device is only limited suitable for supplying elastic yarns and for the pivot lever proves to be a voltage monitor as too insensitive. Due to the inherent elasticity of the The swivel lever reaches its extreme positions during operation (Stops), with the thread tension then out Control is.
  • 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 it is stationary sets 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.
  • 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 yarns.
  • 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 changeover switch allows the changeover from an operating mode with constant regulated thread tension in an operating mode with a defined thread delivery quantity.
  • the knitting point of the circular knitting machine is a corresponding one Thread delivery device assigned so that the to be delivered Thread quantity corresponds to the thread consumption of a knitting point.
  • the thread running speed is correspondingly low.
  • Such a thread delivery device is not for delivery of elastic yarns on knitting machines with high yarn speed and abrupt changes in speed suitable as they occur in flat knitting machines.
  • the thread delivery device is a feeder for threads, Tapes and the like. Thanks to the low moments of inertia of Drive device and thread wheel to rapidly changing thread take-off ratios is customizable. In delivery phases are at full thread consumption yarn speeds up to several meters per second (6th Meters per second). Between delivery phases abrupt standstill and / or rewind phases.
  • the thread store provided enables the Transition between the mentioned amounts of yarn pick up or drop off without the thread tension to change significantly. It serves one essentially path-free sensor device as a voltage sensor for monitoring the thread tension. The one in comparison vanishing to the amount of thread to be stored Measuring stroke of the sensor device enables the thread tension is practically independent of acceleration forces any moving parts of the sensor device adjust.
  • the sensor device is thus Low-mass, highly dynamic and non-reactive.
  • the thread storage and the sensor device are effective separated from each other. In the specific case, this is achieved by keeping the measuring path of the sensor device small essentially perpendicular to the direction of travel the thread stands.
  • Another aspect of the invention is that the entire thread path traversed by the thread is unsprung trained, i.e. all thread guide elements are rigidly mounted. So it succeeds in vibration processes from Machine elements that react to the thread tension could rule out. The only one in the system existing suspension or compliance is due to the Given the inherent elasticity of the thread, in one a thread store specially designed for this purpose is trained.
  • the thread store By using the thread store as a path section between Thread delivery wheel and knitting point is formed in which the elastic yarn is freely stretchable, is a yarn storage created the yarn section to be stored records smoothly. This is achieved by the As a thread storage section of the path dimensioned so long is that with the appropriate yarn from it resulting spring constant falls below a limit. This limit is the quotient of the maximum change in force and maximally to be taken up by the thread store Thread length.
  • the length of the yarn storage Path section is preferably greater than half Meter.
  • the thread delivery device is arranged on the side, i.e. essentially in extension of one of the stitch-forming ones Needles defined row, changed the Path section acting as thread store between thread delivery wheel and thread guide of the knitting machine with the Work cycles of the knitting machine periodically its length.
  • the thread storage device thus changes its absorption capacity. This is due to the situation with flat knitting machines End of the runaway phase, in which the thread guide of the Thread delivery device runs away, insofar as the greatest thread delay occurs at the end of the runaway phase. In the runaway phase, practically one of them double thread consumption corresponding thread quantity supplied. If the thread guide arrives at its turning point and in this initially to rest, the thread consumption drops suddenly to zero. The by a run of the drive device caused subsequent delivery of elastic Yarn can be of its greatest extent Thread store can be absorbed well without the thread tension change sustainably.
  • the from the current position of the thread guide dependent length of the thread store of the thread delivery device thus enables a good adjustment of the absorption capacity of the thread storage to the occurring Deviations of the thread delivery from the actual Thread consumption, especially in the phase-out phases.
  • a sensor for the displacement of the yarn in Contacting element is preferably a Element used that is large with little deflection Emits signal. This can be strain gauges, piezo sensors and the like.
  • the sensor device can be from the thread delivery device be structurally separate. This makes it possible the sensor device as close as possible to the knitting points or to arrange the thread guide. At the knitting points Voltage changes occurring are thus quickly detected and quickly settled.
  • the precision of the control serves it also if the sensor device is a separate Hanging from the knitting machine is decoupled in terms of vibration.
  • the thread delivery device is also designed so that it separated from the knitting machine and / or vibrationally is decoupled from this.
  • the drive device is dependent on the Thread tension controlled by a control device.
  • the It is used to avoid incorrect operation if the control device in all operating modes regardless of the Running speed of the knitting machine works. In order to can be achieved that a thread tension once set even if the machine running speed changes, the thread guide stroke, the knitting pattern or others Influencing variables remain constant. Misalignments that otherwise in the event of a change in the named farm sizes or of the type of yarn could be prevented.
  • the control device can be a PI or a PID controller his.
  • the sufficiently large and especially in its receptivity to the respective position of the Thread guide adapted thread store allows it as Drive device for the thread delivery wheel a stepper motor to use.
  • This preferably as a disc motor executed stepper motor has a high dynamic on, but with acceleration and deceleration specified maximum values are not exceeded can.
  • the corresponding over or under delivery of Yarn is balanced by the thread store.
  • a thread return at the thread guide's reversal point from his running away from the thread delivery wheel Phase to its retreating phase can be balanced if the control device (control circuit) and the drive device are designed so that the thread wheel can run in both directions.
  • the determination of the thread tension can alternatively also take place with two or more sensor devices, which are arranged at different points on the thread path are. From that emitted by the sensor devices Signal becomes an actual signal for the control device educated.
  • At least one filter that as Low or bandpass interference frequencies from the control device keeps away.
  • you can also use band locks or the like can be used.
  • Compensation means for suppressing interference signals can, for example, be provided directly on the sensor device become.
  • Such compensation means are, for example. formed by an identical measuring system that is not of the yarn is affected. With appropriate coordination and a high internal damping represents the difference of the signals emitted by the two sensor devices the thread tension.
  • the thread delivery device 1 shows a thread delivery device 1, an elastic thread 2 (elastomeric yarn) feeds from a bobbin 3 to a flat knitting machine 4, which are only symbolic and excerpts using some stitch-forming needles 5 and a thread guide 6 is shown.
  • the thread delivery device 1 contains a yarn conveyor 7 which is the pulling of the thread 2 from the bobbin 3 and the feed to the Thread guide 6 concerned.
  • the yarn conveyor 7 has a housing 8, in the interior of a not shown and in Fig. 2 schematically indicated stepper motor 9 is arranged is.

  • the sensor device 22, the one with a very short Stroke movably mounted element 25 is as in designed essentially path-free voltage sensor. This deflects the thread 2 vertically, to both Sides of element 25 over two preferably as eyelets trained counterholders 26, 27 runs.
  • the counterholders 26, 27 define the running direction with their connecting line of thread 2, which is orthogonal to the direction of deflection of the element 25.
  • the lateral deflection of the thread 2 is so on the sensor device 22 low that the blunt passed by the thread 2 Angle with vertex on element 25 is greater than 165 °.

  • the movement of the element 25 is there so small that there is no measurable change in voltage of thread 2 is caused.
  • Fig. 2 is between the sensor device 22 and the control device 24 optionally Filter 29 arranged, which filters out interference frequencies. This can from vibrations of the sensor device 22 or from Interference. Incidentally, both are Yarn conveyor device 7 as well as the sensor device 22 hung with low vibration.
  • Thread path is kept as free as possible.
  • the thread 2 runs without deflection and without braking, i.e. without thread brake, on the thread wheel 11 and from this without any significant deflection to the thread guide 6.
  • This guides the elastic thread 2 in each direction of movement a hard basic thread 31 trailing to the needles 5.

  • the stepper motor 9 and the thread wheel 11 are initially still at rest. The one however abruptly starting yarn consumption is initially from the Thread store covered, with the thread tension initially something rises.
  • the control device 24 is increased by the Thread tension causes the stepping motor 9 to accelerate.
  • the thread wheel 11 pulls the thread 2 from the thread spool 3 and feeds it into the thread store 19, whose length increases due to the thread guide 6 running away.
  • the thread wheel 11 After a certain settling time at 42 the thread wheel 11 just delivers that from the flat knitting machine 4 used and received by the thread store 19 Amount of yarn.

This is from the thread store 19 added and if necessary by short Backward feeding of the thread wheel 11 compensated. The then starting yarn consumption is on the move up the near end position 33 is significantly less than in the opposite movement to the far end position 34 to.
