Definitions

  • the present invention relates to a yarn-feeding/recovering method for textile machines and to an apparatus for carrying out such method.
  • weft feeders which are provided with a stationary drum on which a motorized swivel arm winds a plurality of yarn loops forming a stock.
  • the yarn which is unwound from the drum upon request of a textile machine arranged downstream, is subject to a stabilizing brake that maintains the unwinding yarn under a slight tension.
  • the stabilizing brake typically comprises a frustoconical hollow member which is biased with its inner surface against the delivery edge of the drum by manually adjustable elastic means.
  • a controlled brake may be arranged downstream of the feeder, e.g., a foil-based brake of the type described in EP 0622485 .
  • This brake is controlled by a feedback loop which receives a measured tension signal from a sensor, then compares it with a reference tension which is indicative of a desired tension, and finally modulates the braking action in such a way as to minimize the difference between the reference tension and the measured tension.
  • Feeders are also known in which the yarn is wound on a rotary drum, which draws the yarn from a reel and feeds it to the downstream textile machine.
  • the tension of the yarn unwinding from the feeder is controlled by modulating the speed of rotation of the drum, always on the basis of a signal received from a tension sensor as in the previous case. Accordingly, in other words, the change of tension to be applied is determined by the difference between the yarn-feeding speed and the yarn-drawing speed set in the downstream machine.
  • a recovering device of this type is described in EP 1741817 and essentially comprises a motorized reel having an oblique passage defined therein, through which the yarn runs.
  • the passage extends between an inlet port which is axially formed on an end surface of the reel, and an outlet port which is formed on the cylindrical, lateral surface of the reel.
  • a critical issue of the above systems consists in coordinating the operation of the braking system, which operates on the basis of the measured tension of the yarn, with the operation of the recovering system, which is enabled in response to commands sent from the downstream machine on the basis on a predetermined pattern, with consequent difficulties in accurately controlling the feeding parameters and the state of the yarn during the recovering steps, e.g., in relation to possible, accidental events which may occur, such as a yarn breakage.
  • Fig. 1 diagrammatically shows a yarn-feeding/recovering apparatus 10 having a yarn feeder 12 provided with a stationary drum 14 and with a flywheel 16 driven to rotate by a motor 18.
  • the flywheel draws yarn F from a spool 20 and winds it on drum 14 in the shape of loops forming a stock.
  • Yarn F which is unwound from the drum upon request of a general textile machine 22 arranged downstream, is subject to the braking action of a stabilizing brake adapted to maintain the yarn under a slight tension.
  • the stabilizing brake conventionally comprises a frustoconical hollow member 24 which is biased with its inner surface against the delivery edge of drum 14 by elastic means 26.
  • yarn F coming out of stabilizing brake is further subject to the braking action of an electronic yarn-braking device (or brake) 28 which is controlled by a tension control block TC of a control unit CU (which is typically incorporated in yarn feeder 12).
  • Control unit CU is programmed to modulate the braking action applied to yarn F by electronic brake 28, on the basis of a signal received from a tension sensor 30, in such a way as to maintain the tension of the delivered yarn substantially constant on a reference value T_ref.
  • the stock on drum 14 is controlled by a triad of sensors.
  • a first sensor S1 preferably a Hall sensor, detects the passage of magnets M integral with flywheel 16 in order to determine the amount of yarn which is wound on the drum and the winding speed.
  • a speed-evaluating block SE processes signals UWP in order to calculate the yarn comsumption speed on the basis of the time interval between pulses UWP, and generates an enabling signal LE which enables tension control block TC when this speed is higher than a predetermined threshold value, which is preferably equal to zero in the present embodiment.
  • a predetermined threshold value which is preferably equal to zero in the present embodiment.
  • Yarn-recovering device 32 comprises a reel 34 keyed to a drive shaft 36 of a motor 38, preferably a stepping motor or, alternatively, a brushless motor provided with an absolute sensor, in ordet to measure the real position based on techniques conventional in the field.
  • Reel 34 is arranged with its axis A slanting at a first angle ⁇ with respect to the direction of yarn F, indicated by arrow D, so that its end surface 34a facing away from motor 38 obliquely faces the incoming yarn.
  • Reel 34 has an axial cylindrical seat 40 at its end surface 34a.
  • a passage 44 defined within reel 34 extends between an inlet port 44a open to axial cylindrical seat 40, and an outlet port 44b open to the lateral, winding surface 34b of the reel.
  • Passage 44 is rectilinear and is slanting at a second angle ⁇ , which is substantially equal to first angle ⁇ , with respect to axis A of the reel.
  • An internally rounded wearproof ring 46 made of ceramic is applied to the edge of cylindrical seat 40.
  • An inlet yarn-guide eyelet 48 and an outlet yarn-guide eyelet 50 respectively applied upstream and downstream of reel 34 are arranged at the same level of wearproof ring 46.
  • Yarn F passes through upstream yarn-guide eyelet 48, cylindrical seat 40, passage 44 and downstream yarn-guide eyelet 50.
  • motor 38 By operating motor 38, as shown in Fig. 3 , the yarn downstream of the yarn-recovering device is wound on reel 34.
  • yarn-recovering device 32 For a more detailed description of yarn-recovering device 32, reference should be made to EP 1741817 .
  • electronic brake 28 and yarn-recovering device 32 are alternately enabled as a function of the signals from third sensor S3, which are indicative of the yarn comsumption, indipendently from any other operative signals from downstream machine 22.
  • control unit CU continues to modulate the braking action of electronic brake 28 in such a way as to maintain the tension substantially constant at reference value T_ref, while yarn-recovering device remains at a position of minimum interference with the yarn, as shown in Fig. 2 .
  • reel 34 can rotate at a modulated speed in both directions.
  • control unit CU stops reel 34, enables electronic brake 28 again, and then the cycle is repeated.
  • a first condition occurs when N reaches a value N_max corresponding to the maximum amount of yarn which can be stored on the reel. In this case, the process is stopped and an alarm signal is generated.
  • signal LE is used as a comsumption indicator that is indicative of the delivery of yarn from the feeder and, therefore, of the withdrawal of yarn by the downstream machine; on the basis of this indicator, electronic brake 28 and yarn-recovering device 32 are alternately enabled as discussed above.
  • a weft feeder 100 is diagrammatically shown, which is provided with a motorized drum 102 on which yarn F' is wound.
  • Motorized drum 102 draws yarn F' from a spool 104 and delivers it to a textile machine 106 arranged downstream.
  • the tension of yarn F' unwinding from the feeder is conventionally controlled in such a way as to remain substantially constant on a reference value T_ref, by a control unit CU' (which is typically incorporated in yarn feeder 102) provided with a tension control block TC' that modulates the speed of rotation V RP of drum 102 on the basis of the signals from a tension sensor 108 installed on the feeder. Accordingly, the change of tension to be applied is determined by the difference between the yarn-feeding speed and the yarn-drawing speed set in downstream machine 106.
  • a yarn-recovering device 120 is arranged between motorized drum 102 and the tension sensor; in the present embodiment, it is incorporated in housing 103 of feeder 100, as shown in more detail in Figs. 6-11 .
  • Yam-recovering device 120 comprises a motorized reel 122 lying with its axis parallel to the axis of motorized drum 102.
  • the motor (not shown) of reel 122 is preferably a stepping motor or, alternatively, a brushless motor provided with an absolute sensor for measuring its real position.
  • a passage 124 is defined within reel 122, which extends radially between an inlet port 126, which is formed at the middle of a free end 122a of the reel with its axis inclined with respect to the axis of reel 122, and an outlet port 128 formed on the lateral winding surface 122b of the reel.
  • Inlet port 126 and outlet port 128 are internally rounded for reducing the wear by friction.
  • Yarn F' from spool 104 passes through an inlet yarn-guide eyelet 130 attached to the feeder, is wound between drum 12 and an arm 132 of a conventional tension limiter (which does not fall within the scopes of the present invention and, therefore, will not be further disclosed), runs through passage 124 which, at rest, lies at the resting position of Fig. 10 such that it substantially does not interfere with the path of the yarn, then engages a sensing element 134 of tension sensor 108, the latter being also incorporated in housing 103 of the feeder, and finally passes through an outlet yarn-guide eyelet 136 to feed the downstream machine.
  • control unit CU' is conventially received in a seat 138 of feeder 100, which also contains tension sensor 108, and is provided with programming push buttons 140 and with a display 142.
  • drum 12 of the feeder and reel 122 of yarn-recovering device 120 are alternately enabled as a function of speed V RP of drum 102, independently from any other operative signal from the downstream machine.
  • drum 102 continues to rotate at a modulated speed, in such a way as to maintain the tension substantially constant on reference value T_ref, while reel 122 remains at its resting position of Fig. 10 .
  • speed V RP of the drum becomes equal to zero, which circumstance is indicative of the fact that the feeder has stopped to feed yarn and, therefore, the downstream machine has either stopped to draw yarn or started to return it
  • control unit CU' enables reel 122 to recover yarn at a speed V RR modulated in such a way as to maintain the tension substantially constant on a reference value T_ref.
  • the number of revolutions and fractions of revolutions N completed by reel 122 is monitored.
  • reel 122 can rotate in both directions at a modulated speed.
  • control unit CU' stops reel 122, enables drum 102 again, and then the cycle is repeated.
  • an emergency condition by which the tension control can be bypassed.
  • N_max a value corresponding to the maximum amount of yarn which can be stored on the reel
  • the speed V RP of the drum is used as a comsumption indicator, which is indicative of the delivery of yarn by the feeder and, consequently, of the withdrawal of yarn by the downstream machine; on the basis of this indicator, drum 102 and reel 122 are alternately enabled according to the above method.
  • a stabilizing brake as described in EP 1059375 which applies a controlled braking action to the unwinding yarn, could be used in lieu of electronic brake 28.
  • the yarn-recovering device is always positioned in such a way that, at rest, it can assume positions not interfering with the yarn, as shown in Fig. 2 for the first embodiment and in Fig. 10 for the second embodiment.
  • the reel could be arranged in such a way as to deviate the yarn even at its resting position in which it applies the minimum braking action upon the yarn.
