Definitions

  • the invention relates to the technical sector of textile thread processing machines.
  • machines for transforming the yarns by twisting on themselves or by winding on one another based on the rotation of a spindle the twisting or winding being regulated by the ratio between the speed of rotation. the spindle and the speed of advancement of the son (s).
  • the invention relates more particularly to methods for producing yarns resulting from the assembly by twisting, cabling or wrapping of a plurality of yarns of which at least one of the yarns rotated by the spindle, revolves around a member forming around from the latter a "balloon".
  • a member forming around from the latter a "balloon”.
  • wire F
  • balloon the trajectory adopted by the wire in its rotational movement around an organ or the space delimited by this trajectory when the wire rotates.
  • the wire (F) is rotated by means of a pin (3), into which it enters through an axial channel (2) and emerges through a radial channel (4) to join a guide element (10 or 14), fixed or rotating at the same speed as the spindle.
  • a guide element (10 or 14) fixed or rotating at the same speed as the spindle.
  • the wire (F) adopts, in its rotation, a trajectory delimiting a volume of revolution which is designated by "balloon" (6). ).
  • the system is equipped with means known to those skilled in the art such as brakes, capstans, issuers ... (1, 8) able to advance the wire (F) at a predetermined speed, and the reeling and / or the return under adjustable and / or controlled voltages.
  • the problem that the invention proposes to solve is to form a balloon (6) of optimized and stable shape.
  • the radial channel (4) of the spindle (3) opens out on a cylindrical or conical part (5) on which the thread (F) wraps before leaving it to form the balloon (6), by adopting a curved trajectory .
  • the cylindrical or conical portion (5) designated by the skilled person by the term "reserve” or “store”, contributes to ensuring the stability of the balloon (6).
  • a first disadvantage of this solution is that the adjustment of the balance must be done for each type or title of wire and each speed of production.
  • Licences GB982865 , GB1132892 or DE3130614 suggest ways to solve this problem, but not satisfactorily.
  • a second disadvantage of such a solution is that, for a determined volume to accommodate the coil (11) and its unwinding or winding system, the toroidal or ogival trunk type of the balloon (6) determined by the curvilinear trajectory of the wire (F) imposes an external diameter and a high volume, and consequently centrifugal forces, voltages, aerodynamic losses, high energy consumption and bulk.
  • the wire (F) does not take a curvilinear shape under the effect of the centrifugal force, it is kept under a high tension, for example by means of the drive device (1) arranged upstream of the inlet of the spindle acting as a brake.
  • the space delimited by the rotating wire (F) has a shape close to a cylinder which is more advantageous.
  • the arms or disks carrying the wire guide elements (F) reach a diameter substantially equal to that of the balloon, which creates mechanical stresses and high energy consumption.
  • the invention aims to remedy these disadvantages.
  • the invention relates to a method of transforming son by double twisting or direct wiring in which at least one of the threads is rotated by means of a spindle and forms a balloon around a pot or a stationary cradle containing a winding or winding system, and two yarn guiding elements one upstream, the other downstream of the balloon and at least one of which is in the form of an extended radial channel in an arm or disk rotated integrally with the spindle, the wire passing from one to the other of these two elements.
  • the wire which forms the balloon is guided by the radial channel-shaped guide element (s) to a diameter substantially smaller than the maximum diameter of the balloon.
  • the end of the radial channel, from which the wire forms the balloon without winding on a reserve is located at a diameter of between 40% and 80% of the maximum diameter of the balloon.
  • the speed of production is variable, and at least one of the two wire drive systems is driven to obtain a speed which determines, in relation to the speed of rotation of the spindle, the torsion, in number of revolutions per meter, conferred on the thread by the process.
  • Positive or negative corrections of velocities applied to the drive system (s) to maintain the diameter of the balloon at a set value or between two parametric min / max values are calculated from the measurement of the representative magnitude of the diameter averaged over a time representing several turns of the spindle.
  • the positive or negative corrections of speeds applied to the drive system (s) to maintain the diameter of the balloon at a set value or between two set minimum / maximum values are between 0% and 3% of the speed.
  • the positive or negative corrections are made in a fixed increment between 0% and 3% of the speed.
  • the positive or negative corrections are proportional to the difference between the measured value and the reference value representative of the balloon diameter, and capped at a fixed value between 0% and 3% of the speed.
  • maximum diameter (D) of the balloon (6) or “maximum diameter representative value” (D) of the balloon means the maximum diameter, or any diameter measured or evaluated in the zone where it is close to its maximum value, or any value correlated with this diameter.
  • the end of the radial channel (4, 14), from which the wire (F) forms the balloon (6) without winding on a reserve is located on a diameter of between 40% and 80% of the maximum diameter (D) of said balloon (6).
  • the pot or the cradle (7) which contains the unwinding or winding device (12, 13) of the coil (11) is surrounded by one or more coaxial rings (15) with the spindle, used to guide the thread (F), as long as the spindle production speed is not reached and the balloon (6) has not reached its shape and its nominal diameter under the effect of the force centrifugal.
  • the outer surface of said rings is polished and / or surface-treated to allow the yarn (F) to slide by minimizing friction and abrasion during the acceleration and deceleration phases.
  • one of the two wire drive systems (1 or 8) is driven to obtain a speed ( V1 or V2) which determines, in relation to the rotational speed (N) of the spindle (3), the torsion, in number of revolutions per meter, given to the thread (F) by the method.
  • This constant speed can be obtained, for example, by a variable speed drive (23 or 24) performing closed-loop servo of the speed on a constant setpoint.
  • the speed of the second drive system (1 or 8) of the wire (F) should be exactly equal to that of the first, so that the length of wire (F) between the two drive systems (1 and 8) are constant.
  • the speed (V1 or V2) of the second drive system (1 or 8) at an adjustable speed.
  • This adjustable speed can be obtained, for example by a variable speed drive (23 or 24) performing a closed loop control of the speed on an adjustable setpoint.
  • the drive system (1) arranged upstream of the balloon (6), is at a speed ( V1) while the drive system (8) arranged downstream of the balloon (6) is driven at an adjustable speed (V2).
  • V1 the drive system (8) arranged downstream of the balloon (6) is driven at an adjustable speed (V2).
  • V2 the speed of the drive system (8) disposed downstream of the balloon ( 6) is increased, and when the magnitude representative of the maximum diameter (D) of the balloon (6) is less than the setpoint value and / or the minimum parameterized value, said speed (V2) is decreased.
  • the drive system (8) disposed downstream of the balloon (6) is at fixed speed (V2), and the drive system (1) arranged upstream of the balloon (6) is driven at an adjustable speed (V1).
  • V2 fixed speed
  • V1 adjustable speed
  • the speed (V1) of the drive system (1) disposed upstream of the balloon ( 6) is decreased, and when the magnitude representative of the maximum diameter (D) of the balloon (6) is less than the setpoint value and / or the parameterized minimum value, said speed (V1) is increased.
  • the speed of production is variable, and at least one of the two drive systems (1 or 8) of the wire (F) is controlled to obtain a speed (V1 or V2) which determines, in relation to the rotational speed (N) of the spindle (3), the torsion, in number of revolutions per meter, imparted to the thread by the method.
  • the positive or negative corrections of speeds (V1 or V2) applied to the drive system (s) (1 and / or 8) for maintaining the diameter (D) of the flask (6) at a set point or between two parameterized minimum / maximum values are established by comparison between the measured value of the quantity representative of the diameter (D) of the flask (6) and the setpoint and / or the minimum and maximum values. Due to the flexible and elastic nature of the yarn (F) and the fact that the instantaneous shape of the balloon (6) results from an equilibrium between the tensions, the aerodynamic forces and the centrifugal force, the maximum diameter (D) is subject to instantaneous variations or instabilities that are not representative of a drift.
  • the invention also relates to a device for twisting or wiring wires by means of a pin (3), at least one of the wires being rotated to form a balloon (6) around a pot or a fixed cradle (7).
  • the torque or power absorbed by the spindle (3) to rotate it increases sharply when the maximum diameter (D) of the balloon (6) increases and so that the measurement of this power, this torque, or the current absorbed by the motor driving the pin provides a magnitude representative of the maximum diameter (D).
  • the maximum diameter setpoint (D) or the minimum / maximum values to be obtained are converted into a setpoint or minimum / maximum value of power, torque or voltage current valid for a type and a wire title and for a speed of brooch.
  • the direct measurement of the diameter (D) of the balloon (6) can also be carried out by optical means.
  • the Figures 5 and 6 show an exemplary embodiment of such a measurement by means of a device composed of at least two "optical barrier” (17), composed of a light source (18) and a photosensitive detector (19) between which a light beam is established, the interruption of which is detected by the passage of the wire (F) from the balloon (6).
  • the two "optical barriers” are positioned so that one is cut when the balloon reaches the minimum diameter and the other the maximum diameter targeted.
  • a logical treatment of the output of the two optical barriers indicates whether the diameter (D) of the balloon is less than the minimum, in the minimum / maximum values, or greater than the maximum value targeted.
  • the figure 7 shows an exemplary embodiment of such a measurement by means of a device consisting of a linear or matrix CCD type optical sensor (20) associated with a ray-shaped light source (21) (for example LED or laser) .
  • a ray-shaped light source (21) for example LED or laser
  • the light ray is directed radially towards the axis of the spindle in line with the zone where the diameter of the balloon (6) is maximum, when the wire intersects said radius, it is emitted by reflection a light signal captured by the sensor CCD, a treatment locates the point of emission (22) along the axis parallel to the radius, which is representative of the diameter of the balloon at this point.
  • An alternative embodiment by means of a matrix CCD type optical sensor associated with a stroboscopic light source synchronized with the rotation of the spindle, makes it possible to capture the image in two dimensions and therefore the shape of the wire (F) forming the balloon (6) when illuminated by lightning, and to deduce the diameter (D).
  • the measurement of a magnitude representative of the diameter of the balloon can also be evaluated by means of an acoustic sensor disposed near the balloon (6). Due to its rotation in the air, the wire (F) generates an aerodynamic pressure wave detectable by a nearby acoustic sensor such as a microphone. The intensity of the signal detects, for a speed of rotation and a given type of wire, increases strongly when the distance between the balloon and the sensor decreases and therefore provides a magnitude representative of the diameter of the balloon. According to this means, the diameter setpoint (D) or the minimum / maximum values to be obtained are converted into a setpoint or minimum / maximum value of the intensity of the acoustic wave, valid for a type and a title of wire and for a spindle speed.
  • the measurement of a magnitude representative of the diameter of the balloon can also be evaluated by means of a force or vibration sensor, associated with a mechanical element arranged tangentially on the surface of the balloon (6). Due to its rotation in the air, the wire (F) creates friction or impact on the element a force or vibration detectable by the sensor. The intensity of the detected signal, for a given speed of rotation and a given type of wire, increases strongly when the trajectory of the balloon interferes with the mechanical element. Since the mechanical element is arranged in a position tangent to the minimum target diameter, the diameter setpoint (D) or the minimum / maximum values to be obtained are converted into a minimum / maximum value value value of the intensity of the force or vibration. detected, valid for a type and a wire title and for a spindle speed.
  • the advantages are apparent in the description.
  • the invention proposes a simple and reliable solution for forming a stable balloon, in particular for double-twist or direct-wiring processes, by using means for guiding the wire of reduced diameter, while offering a particularly advantageous volume in the balloon. This results on the one hand a significantly reduced power consumption, and on the other hand a voltage in the wire in the balloon much lower, compared to conventional methods.
