Definitions

  • the present invention relates to a method for operating a spindle of a double wire twisting or cabling machine according to the preamble of claim 1 and a double wire twisting or cabling machine according to the preamble of claim 8.
  • the spindle of a double-wire twisting or cabling machine is used to produce twists, wrapping threads or the like from at least two threads drawn from bobbins, which are generally referred to as inner thread or outer thread.
  • the bobbin for the inner thread is often positioned in a so-called bobbin pot, which is supported on a thread deflection device in the region of the axis of rotation of the spindle and is secured against rotation by magnets.
  • the bobbin of the associated outer thread preferably hangs in a creel which is arranged above or behind the double-wire twisting or cabling machine.
  • the outer thread starting from the outer thread brake, is inserted centrally into a cord spindle and exits radially on a rotating storage disk which is attached to the cord spindle below a twisting plate.
  • the outer thread wraps around the storage disk, which compensates for thread tensions arising from thread supply fluctuations, at least partially, before the thread is transferred over the outer edge of the twisting plate into a free thread balloon, the shape and diameter of which depend on various factors. Some of these factors are, for example, the diameter of the storage disc and the twist plate, the balloon height, the titer of the thread and the spindle speed of the job.
  • a cabling device in which a balloon limiting pot prevents the formation of a free thread balloon. This means that the outer thread rotating around the spindle is limited in its radial extent by a rotating pot. Furthermore, due to the friction of the running outer thread on the inner wall of the balloon limiting pot, the thread tension is regulated, which corresponds to the effect of using a storage disk.
  • the thread tension of the outer thread is lower than that of the DE 41 21 913 A1 known cabling device with a storage disk, which by the EP 1 167 597 B1 known cabling device
  • the rotating balloon limiting pot is exposed to a not insignificant wear from the running outer thread and the balloon limiting pot must also be constantly moved as a rotating mass by the spindle drive.
  • the air friction of the rotating balloon limiting pot creates additional losses that have to be compensated for by the spindle drive.
  • a method for operating a spindle of a double-wire twisting or cabling machine, which is characterized by a reduced energy consumption, and an associated double-wire twisting or cabling machine are in the DE 10 2008 033 849 A1 described.
  • thread-turning devices In connection with the spindles of double-wire twisting or cabling machines, thread-turning devices are also known which are designed, for example, in the manner of a wing.
  • the object of the invention is to develop a method for operating a spindle of a double-wire twisting or cabling machine which, on the one hand, is characterized by a reduced energy consumption and, on the other hand, ensures safe, correct operation of the spindles at all times.
  • This object is achieved according to the invention by a method for operating a spindle at a work station of a double-wire twisting or cabling machine, in which an outer thread is drawn off from a supply spool and orbits the spindle in a thread balloon.
  • the work station of the double-wire twisting or cabling machine has a bobbin, a rotatably mounted thread deflecting device, a device for forming a twisting or cabling point, a device for influencing the balloon thread tension via which the thread balloon shape can be adjusted, and a control loop.
  • the work station is operated without a storage disk and the thread balloon is driven via a fixed ejection point on a rotatable thread deflection device, the control loop regulating the device for influencing the balloon thread tension in such a way that there is always a minimum thread balloon size, with a fixed predetermined one Throwing geometry of the outer thread results from the fixed dropping point of the thread deflecting device, and due to the fixed dropping point of the thread deflecting device and the increased thread tension in the area of the fixed dropping point, a dropping angle of the outer thread is automatically set, which leads to a minimization of the diameter of the free thread balloon being formed.
  • the associated double wire twisting or cabling machine has the features described in claim 4.
  • the method according to the invention not only has the advantage that the spindle has a good energy balance during the twisting or cabling process due to the thread balloon being minimized in diameter, but the omission of any storage of the outer thread during the entire operating time also leads to a very gentle treatment of the Thread material. This means that not using a storage disk generates various other, not inconsiderable advantages in addition to the saving of components, which can be quite expensive.
  • the lower surface variance resulting from the omission of a storage disk leads, for example, to improved concentricity properties of the spindle and thus to an improved vibration behavior of this component.
  • the method according to the invention not only avoids that yarn damage due to greater surface contact of the thread material with a storage disc or with a balloon limiting pot, but also due to the shape and size of the diameter of the thread balloons surrounding the spindle, the prevailing one is also easy Thread tension recognizable, which can be easily corrected if necessary.
  • the control loop regulates the device for influencing the balloon thread tension in such a way that a minimum thread balloon size is automatically obtained.
  • This device for influencing the balloon thread tension keeps the feeding speed of the thread as constant as possible, or, through continuous adaptation, fluctuations in the delivery of the thread, which lead to breakage of the thread or to fluctuations in the shape and size of the rotating thread balloon avoided.
  • the rotatably mounted thread deflection device is designed as a wrap-around brake, in which only a relatively small thread storage volume is used.
  • the device for influencing the balloon thread tension is preferably connected to a control circuit which regulates the device in such a way that a desired thread balloon size can be set.
  • control loop also regulates the device for influencing the balloon thread tension when the spindle is raised or lowered and in the event of a short-term voltage voltage interruption in such a way that a thread balloon size results in which both a contact with the fixed spindle cup and a contact between the two Separators arranged at work stations is avoided.
  • Such a design enables a compact construction of the work stations with a reduced division of work stations compared to known double wire twisting or cabling machines, with the result that the space required for installing the double wire twisting or cabling machines according to the invention is reduced.
  • the double-wire twisting or cabling machine has a large number of workstations, each of which has a spindle, a bobbin pot, a thread deflection device mounted in rotation, a device for forming a twisting or cabling point, and a device for influencing the balloon thread tension via which the thread balloon shape is adjustable and has a control loop.
  • the work station is designed without a storage disc and the rotatably mounted thread deflection device has a fixed ejection point for the outer thread, the control loop being set up in such a way that the device for influencing the balloon thread tension can be regulated in such a way that there is always a minimal thread balloon size, which results in results in a fixed discharge geometry of the outer thread from the fixed discharge point of the thread deflection device, and due to the fixed discharge point of the thread deflection device and the increased thread tension in the area of the fixed discharge point, a discharge angle of the outer thread automatically arises, which minimizes the diameter of the free thread balloon being formed leads.
  • Such a design not only has the advantage that fewer components per spindle are required because there is no storage disc or a rotating balloon limiting pot, but due to the fixed ejection point on the rotatably mounted thread deflection device, proper rotation of the thread balloon is also ensured at all times.
  • the fixed discharge point on the rotatably mounted thread deflection device can have different embodiments.
  • the fixed drop point can be formed, for example, by an eyelet which is arranged in the outer region of a twisting plate or in the free end region of a twisting wing.
  • the fixed discharge point is formed by the exit of a closed channel, which preferably extends between a thread outlet bore in the region of the axis of rotation of the spindle and the outer region of a twist plate, or between a thread outlet bore in the region of the axis of rotation of the spindle and the end region of a twist wing .
  • the fixed discharge point is formed by the end of a slot which is open at the bottom and which, for example, is between a thread outlet bore in the region of the axis of rotation of the spindle and the outer region of a twist plate or between a thread outlet bore in the region of the axis of rotation of the spindle and the end region of a twine wing is arranged.
  • the fixed discharge point is part of a rotatably mounted belt brake.
  • Such a wrap-around brake preferably has a hub-like base body with a thread guide bore running axially with respect to the axis of rotation of the spindle and a thread outlet bore extending radially therefrom.
  • the wrap-around brake has a plate-shaped attachment connected to the base body, which is equipped with a fixed ejection point for the thread, preferably with an abrasion-resistant eyelet.
  • the twisting plates, the twisting wings and / or the wrapping brake are preferably designed in such a way that they are self-threading. That is, when you restart the thread is automatically threaded into the drop point of the thread deflecting device.
  • the controllable device for influencing the balloon thread tension is preferably designed either as a brake or as an active delivery mechanism. This means that the thread deflection device is preceded by a controllable device for influencing the thread tension, by means of which the feed speed of the thread is adjusted so that the thread tension of the thread entering the thread deflection device always has a value which is a function of the diameter of the thread balloon orbiting the spindle minimizes the geometry of the spindle, which has a positive influence on the energy consumption of the spindle drive.
  • a work station of a double-wire twisting or cabling machine is generally identified with the reference number 1.
  • the method according to the invention is also explained below on the basis of the illustrated work station 1.
  • the work station 1 of the double-wire twisting or cabling machine has, as usual, a gate 4 which is generally positioned above or behind the work station 1 and which serves to receive at least one first supply spool 7, from which a so-called outer thread 5 is drawn off.
  • the work station 1 also has a spindle 2, which in the present exemplary embodiment is designed as a so-called cabling spindle.
  • the spindle 2 has a bobbin 19 in which a second supply bobbin 15 is mounted, from which a so-called inner thread 16 is drawn off overhead, which is fed to a balloon eyelet arranged above the spindle 2 or a so-called compensation system 9.
  • the bobbin 19 is mounted on the rotatable thread deflection device 20, which in the embodiment of the Fig. 1 is designed as a twist plate 8.
  • the bobbin 19 supported on the rotatable thread deflection device 20 is secured against rotation, preferably by a magnetic device (not shown).
  • the thread deflection device 20 of the spindle 2 is acted upon by a spindle drive 3, which, as in the exemplary embodiment, can be either a direct drive or an indirect drive. In the latter case, the thread deflection device 20 is connected to a corresponding drive, for example via a belt drive.
  • the outer thread 5 drawn off from the first supply spool 7 is fed to a controllable device 6 arranged in the thread run between the creel 4 and the spindle 2 for influencing the thread tension.
  • the device 6 is connected via control lines 27 to a control circuit 18 which controls the thread tension applied by the device 6 to the outer thread 5.
  • the device 6 for influencing the thread tension in the thread running direction is arranged in front of the thread deflection device 20, which in the exemplary embodiment is designed as a twist plate 8.
  • the outer thread 5 passes through the spindle drive 3 in the region of the axis of rotation 28 of the spindle drive after the device 6 and emerges from the hollow axis of rotation 28 of the spindle drive 3 in the radial direction below the twist plate 8 through a so-called thread outlet bore 29.
  • the outer thread 5 then runs to the outer region 30 of the twisting plate 8, where a fixed drop point 21 for the outer thread 5 is installed.
  • This fixed drop point 21 can, as in the embodiment of FIG Fig. 1 shown, are formed as an eyelet 23.
  • the outer thread 5 is deflected upward in the area of the eyelet 23 of the twisting plate 8 and circles around the bobbin 19 of the spindle 2, in which a second supply bobbin 15 is positioned, forming a free thread balloon B.
  • the outer thread 5 drawn off from the first supply bobbin 7 and the inner thread 16 drawn off from the second supply bobbin 15 are brought together in the region of the balloon eyelet or the compensation system 9.
  • the position of the balloon eyelet or the compensation system 9 determines the height of the free thread balloon B that is formed.
  • there is the so-called cabling or cording point in which the two threads, the outer thread 5 and the inner thread 16, converge and form a cord thread 17, for example.
  • a thread draw-off device 10 is arranged above the cabling point, by means of which the cord thread 17 is drawn off and fed to a winding and winding device 12 via a compensating element, such as a dancer device 11.
  • the winding and winding device 12 has, as usual, a drive roller 13 and a spool 14 driven by the drive roller 13 with a friction fit.

  • the controllable thread tension applied by the device 6 to the outer thread 5 preferably has an order of magnitude which, depending on the geometry of the spindle 2, leads to a minimization of the free thread balloon B.

It is important that in order to maintain the free thread balloon B with a constant, minimized diameter, the device 6 always has an active, controllable influence on the thread tension. That is, the control circuit 18 connected to the device 6 via control lines 27 uses, for example, the tension of the outer thread 5 before or after the formation of the free thread balloon B as the manipulated variable.
