Definitions

  • the present invention relates to a modulated thread braking device in weft feeders for shuttle-less looms and in particular for gripper, bullet and pneumatic looms.
  • weft feeders are devices which comprise a fixed drum on which a rotating arm winds a plurality of turns of thread which constitute a loom feed reserve. At each beat, the loom removes a certain number of threads from said reserve, and the thread which unwinds from the drum of the feeder is subjected to braking means which allow to control its mechanical tension.
  • Brush brakes of the first type, are constituted by a ring of bristles, typically made of synthetic fibers, arranged inside a ring which surrounds the feeder drum. The bristles are in contact with the drum, and by means of their elastic action they brake the thread which unwinds from said drum.
  • Lamina brakes of the second type, are constituted by a ring of individual elastically yielding metallic laminae or fingers which are arranged in a row along the generatrices of a rotational solid, such as a conoid or a paraboloid, and also elastically engage the surface of the drum.
  • the thread For a correct weaving process, the thread must be subjected to adequate mechanical tension during the entire beat cycle.
  • the thread must be subjected to adequate tension -- hereinafter termed static tension -- even when its speed becomes zero, for example during the exchange of the thread among the clamps, or when the weft is released at the sides of the portion of fabric.
  • the static tension of the thread is set by means of adjustment elements which act on the braking means; said elements vary the contact pressure between the braking means and the thread which runs in contact with the drum of the feeder. Said tension cannot drop below a given value in order to avoid the presence of slack wefts on the sides of the portion of fabric being formed. Said static tension, which is normally set to the minimum value compatible with these requirements, reaches -- as the thread advancement speed increases -- values which are percentually much higher, and with modern looms it is easy to reach 700% increases in static tension. It is easily understood that this causes easy and frequent breakages of the thread during the weaving process.
  • Said known braking element is generally used in combination with a brush braking means and is constituted by a movable annular disk which is arranged coaxially to the drum of the feeder and in front of it in the thread exit direction.
  • the outer diameter of the disk is much smaller than the diameter of the drum of the feeder, for example 60-70% smaller, and the thread is pressed with a variable elastic force between said annular disk and a corresponding protruding central part of the drum .
  • the movable disk is subjected to the elastic load of a spring and is rigidly coupled to the movable element of an electromagnet which is supplied with a current which varies proportionally to the speed of the loom. By virtue of this electromagnet, the elastic load of the spring which acts on the disk is modulated proportionally to the speed of the loom.
  • a device according to the preamble of claim 1 is disclosed in document WO-A-9 114 032.
  • the aim of the present invention is essentially to eliminate these severe problems and, within the scope of this general aim, an important object of said invention is to provide a device for positively modulated braking which can control the unwinding of the thread from the drum of the feeder and can vary the braking action applied to the thread proportionally with respect to the mechanical tension which acts on said thread in order to keep said tension substantially constant, for example within variation limits not higher than 20-50% of the static tension.
  • Another important object of the present invention is to provide a device which is constructively very simple and can respond, in terms of adaptation of the braking action applied to the thread, even to instantaneous changes in the mechanical tension of said thread.
  • This high sensitivity of the device in practice allows the passage of any knots present on the thread, without producing such stresses as to cause its breakage.
  • a positive modulated braking device which comprises a braking body which has a continuous circular extension, typically a truncated-cone body, is supported by elastic means frontally and coaxially with respect to the drum of the feeder and is actuated by said means into elastic contact engagement with its larger cross-section against said drum along a circumference of the drum which is slightly smaller than the maximum one, in that the thread runs between said drum and said braking body along an inclined path which extends between the tangency circumference of the braking body with respect to the drum and the smaller cross-section of the braking body and in that the braking body has, at its smaller cross-section, a cylindrical portion which is rigidly coupled thereto, extends into the annular gap of the skirt of a permanent magnet and is provided with a coil which is supplied with an energization current which is modulated in accordance with the variations in the mechanical tension of the thread; means
  • FIG 1 shows a weft feeder 10 with a fixed drum T on which a hollow rotating arm 11 winds a plurality of turns of thread SF which constitute a weft reserve.
  • the rotating arm 11 is rigidly coupled to an equally hollow drive shaft AM of the feeder 10, and the thread F which arrives from the spool of thread, which is not illustrated, runs in the cavity of said shaft and of said arm.
  • the braking means is constituted by a braking body 12 which has a continuous circular extension and is typically a truncated-cone body.
  • the generatrices of the braking body 12 are preferably straight, but this is non-limitative and it is equally possible to use bodies such as 12 with curved generatrices, for example parabolic ones.
  • An elastic means is provided in order to support the truncated-cone braking body 12 frontally and coaxially to the drum T, with its larger cross-section directed toward said drum. The elastic means furthermore actuates the braking body 12 into elastic contact engagement with the drum along a circumference C1 thereof, termed tangency circumference, which is slightly smaller than the maximum circumference of said drum.
  • the elastic means is constituted by a lamina 13 which is centrally perforated and is made of metal or synthetic material or cardboard impregnated with synthetic resin.
  • the lamina 13 surrounds the body 12 with the edge of its central hole, for example at the smaller cross-section of said body, and has a surface which is elastically deformable along a direction which is parallel to the axis of the drum T.
  • the axial elasticity of the laminae 13 is obtained by means of concentric undulations 130 formed on the surface of said laminae.
  • the lamina 13 is provided with a lobed outer contour 131 and with a double series of punched openings 132-133 which surround the central hole 134 which is meant to surround the truncated-cone body 12.
  • Each one of the openings 132-133 extends through an arc of approximately 120° and delimits corresponding series of radial spokes 135-136.
  • the arrangement is advantageous, since it provides the lamina 13 with high elasticity in an axial direction and at the same time with adequate rigidity in a radial direction.
  • the support 14 is rigidly coupled, by means of a rigid arm 150, to a slider 15 which can slide on a guide 16 which is arranged parallel to the drum T.
  • a known traction device for example of the screw-and-nut type, provided with an actuation knob 17, allows to move the slider 15 along the guide 16 and consequently to move the support 14 in order to vary the elastic force with which the body 12 presses on the drum T. This allows to adjust the static tension applied to the thread F.
  • the braking body 12 is made of a high-strength synthetic material, for example a fabric or laminate of carbon fibers impregnated with polymeric resin, and has a cylindrical portion 120 at its smaller cross-section. Said cylindrical portion 120 extends into the annular gap of a skirt 18 of magnetic material which surrounds an annular permanent magnet 19.
  • the skirt 18, which is contained in the cup-shaped support 14, is formed by two disks 18a-18b and by a perforated hub which delimits said annular gap together with the disk 18a; the thread F which exits from the device 10 passes through the hole in the hub.
  • a winding 20 is arranged on the extension 120 and is supplied with an energization current I which is modulated and can vary in accordance with the variations in the mechanical tension of the thread detected by a tension sensor S which probes said thread.
  • the current I interacts with the magnetic field produced by the magnet 19 and generates a magnetomotive force which acts in order to vary, in a correspondingly modulated manner, the contact pressure of the truncated-cone body 12 on the drum T.
  • the sensor for the mechanical tension of the thread is constituted by a thread guiding eyelet 21 which is arranged adjacent to the smaller cross-section of the truncated-cone body 12.
  • the thread F extends from the tangency circumference C1 of the drum T to the eyelet 21 and forms, with respect to the axis of the drum T, an angle which is greater than the taper of the truncated-cone braking body 12; therefore the truncated-cone braking body 12 engages the thread only at said tangency circumference.
  • the eyelet 21 is supported at the free end of an elastic arm 22, and figure 2 shows that the other end of the arm 22 is rigidly coupled, by means of an L-shaped wing 220, to the rigid arm 150.
  • the wing 220 has a free arm portion 221.
  • Four strain gauges, designated by the reference numerals 23 to 26, are arranged on the arm 22 and on the arm portion 221 and are located in pairs on both faces of said arm and of said arm portion.
  • the four strain gauges 23 to 26 are connected with a bridge-like arrangement P, as shown in the detail view of figure 3, and the diagonal of the bridge P is connected to the inputs of a differential amplifier A which provides in output a signal "t" which is proportional to the mechanical tension of the thread.
  • the described arrangement for the four strain gauges 23 to 26 eliminates any noise signals due to the vibrations of the feeder 10, and the signal "t" correctly depends only on the mechanical tension of the thread.
  • the signal t present at the output of the amplifier A is sent to a microprocessor ⁇ P.
  • the microprocessor also receives a signal "to", for example set by means of a keyboard 27, which represents the maximum tension which the thread can reach during the beat of the loom, and a synchronization signal “s” provided by the loom TE.
  • a control signal “c” is output by the microprocessor ⁇ P and drives an amplifier B which provides in output the energization current I, modulated proportionally to the variation in the mechanical tension of the thread with respect to said maximum tension "to", which supplies the winding 20.
  • the microprocessor ⁇ P is programmed to provide a signal to the amplifier B such that the corresponding energization current I allows to keep the signal "t" within values equal to 20-50% of the preset signal "to".
  • the means for sensing the mechanical tension of the thread is constituted by a probe 28 with rollers which is located externally to the feeder 10 and is not rigidly coupled thereto.
  • the probe 28 can be of the known type with three rollers, wherein the central roller is supported by an elastic arm (not illustrated) with which at least one strain gauge is associated, said strain gauge being capable of providing a tension signal "t" which is proportional to the stress which the thread discharges onto said central roller.
  • the truncated-cone braking body 12 has a greater taper than the angle which the thread forms with respect to the axis of the drum T and constitutes, with its smaller cross-section, a thread guide for the thread F arranged upstream of the hole of the hub of the skirt 18.
  • the smaller cross-section of the truncated-cone braking body 12 is surrounded by a protruding ring 210 which extends slightly inside the truncated-cone braking body 12. Consequently, the thread is in contact with the body 12 only at the points of the tangency circumference C1 and at the points of the ring 210. In this manner the thread, which rotates clockwise with respect to the truncated-cone braking body 12, is not subjected to unwanted torsions and provides a self-cleaning action as regards lint and other deposits which tend to accumulate on the truncated-cone body.
  • the cylindrical portion 120 which extends in the annular gap of the skirt 18 and is provided with the winding 20 is associated with the smaller cross-section of the truncated-cone braking body 12.
  • the energization current I is fed to the winding 20 by the amplifier B under the control of the microprocessor ⁇ P, and said microprocessor receives the signal "t" which corresponds to the mechanical tension of the thread from the probe 28 with the interposition of the amplifier A.
  • this function is performed by an optical sensor 30 which detects the turns which unwind from the drum T.
  • the sensor 30 is associated with a counter 31 whose output is connected to a timer 32 which is in turn connected to the microprocessor ⁇ P.
  • the counter 31 after the unwinding of a preset integer number of turns of thread, activates the timer 32 which, after a time which corresponds to the unwinding of the possible fraction of a turn K, issues a stop signal "a".
  • the microprocessor ⁇ P by means of the amplifier B, energizes the coil 20 with a stop current which pushes the truncated-cone.body 12 against the drum T with a force which is sufficient to prevent the further advancement of the thread F.
