Definitions

  • the invention relates to a device for the simultaneous delivery of several threads with two spacing parallel friction rollers, the peripheral speed is higher than the thread take-off speed.
  • the invention is therefore based on the object of designing a thread delivery device with two friction rollers of parallel spacing parallel to one another of the type mentioned at the outset in such a way that they also provide guidance and individual control allows multiple threads over a very wide wrap angle range.
  • all mutually interacting but not necessarily jointly controllable swivel arm pairs of which one swivel arm is assigned to the first and the other swivel arm to the second friction roller, can have at their free ends two thread deflecting rollers arranged with parallel axes.
  • any number of swivel arms for guiding separate threads can be arranged over a correspondingly wide, identical friction roller.
  • the thread delivery device can also have two friction rollers running parallel to one another at a distance, with each thread guided over both friction rollers being assigned at least one thread guide element arranged on a swivel arm on each friction roller and the thread guide elements being all pivotable into the distance between the two friction rollers.
  • each of several threads can be individually influenced in its feed rate, and wrap angles can be set on the friction rollers, which can be from 0 ° (lifting the thread from the friction roller) to over 270 °.
  • the swivel arms of the thread delivery device according to the invention can be arranged on a common axis running outside an associated friction roller, so that they can also be coupled together for a common adjustment if necessary.
  • the associated friction roller can advantageously be designed as a continuous long roller with a stepped surface, so that after a thread break forming thread winding of each of the driven threads can be pushed over a free end of the friction roller after pivoting the adjacent threads.
  • a thread delivery device designed according to the invention is particularly suitable for textile machines, for example flat knitting machines, with an automatic regulation of the thread feed, the tension of the individual threads being measured and an adjustment motor assigned to each individual swivel arm and acting on it being driven depending on the measured thread tension.
  • end stops can be expediently provided, which limit its swivel range overall, with an infinitely adjustable intermediate stop being arranged within the maximum wrap range defined by the end stops, with which a swivel angle determined as favorable can be determined such that a swivel arm after one temporary pivoting can be pivoted back into this convenient position.
  • the thread guiding device shown has a flat and essentially circular cylindrical housing 10, in which two friction rollers 11 and 12 projecting over the one end face of the housing 10 and running parallel to one another at a distance are overhung.
  • An electric motor 13 is flanged to the other end face of the housing 10 and drives the two friction rollers 11 and 12 at a peripheral speed that is greater than a desired thread take-off speed via a gear (not shown) housed in the housing 10.
  • a rod 14 is fastened in the housing 10, on each of which several of two types of swivel arms 15 and 16 are alternately supported in succession.
  • the swivel arms 15 are the friction roller 12 and the swivel arms 16 are assigned to the friction roller 11.
  • the pivot arms 15 and 16 are substantially longer than the diameter of the friction rollers 11 and 12 and curved so that they can be seen from their support rod 14 in the space between the two friction rollers 11 and 12 through the common imaginary connection plane of the axes 11.1 and 12.1 of the two friction rollers 11 can be pivoted through without touching the friction rollers 11, 12.
  • Each swivel arm 15, 16 carries at its free end two deflection rollers 15/1, 15/2 or 16/1, 16/2, which are mounted parallel to one another and freely rotatable.
  • the plurality of threads to be driven are first fed to the friction roller 11 via a thread guide rail 18 which is shown in FIG. 2 and is provided with thread guide eyelets 17. For reasons of clarity, only a single thread 20 is shown in the drawing. 1, the thread passes through a thread guide eyelet 17 of the thread guide rail onto the friction roller 11. Its wrap angle around the friction roller 11 is determined by the deflection roller 16/2 of a swivel arm 16, through which the thread is derived from the friction roller 11 and passed to the friction roller 12 becomes.
  • the wrap angle alpha 2 of the thread 20 around the friction roller 12 is determined by the deflecting roller 15/2 of a swivel arm 15 adjacent to the swivel arm 16, through which the thread is lifted from the friction roller 12 and passed again to the friction roller 11.
  • the thread 20 is finally discharged downward from the friction roller 11 to a thread guide member, not shown.
  • both pivot arms 15 and 16 are also shown with dash-dotted lines in a second pivot position, in which they each give the thread 20 'also drawn for this position a smaller wrap angle betta 1 and betta 2 around the friction rollers 11 and 12.
  • the thread 20 ' is guided over the deflection rollers 15/1 and 16/1.
  • the swivel arms 15 and 16 can be adjusted by hand using a grip pin 19 indicated in FIG. 1.
  • This grip pin can be assigned to an intermediate stop, not shown, which is infinitely adjustable between end stops and with which a swivel arm setting can be fixed.
  • the end stops can be determined, for example, by the ends of guide slots 21, one of which is also indicated in FIG. 2.
  • each of the swivel arms 15 and 16 is assigned an adjusting motor 22 which engages the swivel arms 15 or 16 on a second arm, here on an arm 16/3 of a swivel arm 16.
  • Each thread is passed in the direction of travel behind the thread delivery device via a thread tension meter 23, which supplies a control signal to a control circuit 24, from which the individual adjustment motors 22 receive their adjustment signals, for example adjustment pulses.
  • the drive motors can have any suitable structure. All swivel arms 15 and / or all swivel arms 16 can also have a thru-axle, not shown, for which the swivel arms have a through-opening 25, are positively coupled to one another so that all swivel arms 15 or 16 can be adjusted together, for example by means of a single drive motor 22.
