Definitions

  • the invention relates to a method for controlling the supply voltage and to a power device of at least one weft thread for a loom sickle.
  • the invention also relates to a profession weave equipped with such a feeding device.
  • the rotational speed of the donor must be synchronized with that of the sickle, which implies the use of complex mechanical devices, in particular of the type reducers and / or springs of compensation.
  • the known devices are therefore relatively expensive and their adjustment can be particularly long and tedious.
  • EP-A-0 851 833 or from EP-A-0 619 261 to control a brake of a frame donor in function of the downstream weft thread tension. It is also known from EP-A-0 467 059 to enslave the position a lever forming a voltage regulator. These devices are not effective enough to be associated with a trade to sickle.
  • the invention relates to a method of controlling the supply voltage of at least one wire weft, in a loom having at least one sickle from a supply of yarn, process in which at least over is subject to the action of a donor raster and a compensation device of its accelerations / decelerations, this device comprising a movable member defining the trajectory of the wire of frame.
  • This method is characterized in that it comprises a step of controlling the operation of a electric actuator for driving at least one drum of the frame donor according to a representative signal of the operation of a second electric actuator which drive itself the aforementioned movable member.
  • the frame donor can, by the angular position of its drum, not only provide the just enough thread needed for weaving but also smooth some of the accelerations / decelerations of the frame, which makes it possible to limit in the necessary compensation.
  • compensating device or "compensator” of the invention makes it possible not only to smooth some of the violent acceleration / deceleration of the frame, but also to a certain extent to fix the tension of the weft yarn regardless of its angular position. he also allows you to adjust the speed of the according to the frame requirement, allowing variable unwinding speeds.
  • the invention also relates to a device weft feed of a loom with at least one sickle that allows to put in a process as previously described and, more specifically, a device comprising a reserve of weft threads, at least one thread drive drum frame and at least one compensation device for its accelerations / decelerations of this thread which comprises a movable member defining the trajectory of the weft yarn.
  • This device is characterized in that the drum is driven in rotation by a first electric actuator, in that the movable member is driven by a second electric actuator and in that means are provided to measure the position of the aforementioned movable member, then that means are also provided to control the first electric actuator according to the result of the measurement carried out by the measuring means.
  • the position of the drum training which belongs in practice to the frame donor, can be ordered in a way to constantly adapt to the movements of back and forth sickle and compensate for some of the violent accelerations and decelerations of the weft thread resulting from it.
  • the invention finally relates to a loom for sickle equipped with a feeding device such as described above.
  • a feeding device such as described above.
  • the device represented in FIGS. 1 and 2 is intended to allow the weft feed of a sickle 1 animated with an oscillating pivoting movement, represented by the arrow F 2 , around a fixed point 2.
  • the weft thread 3 is moved relative to the warp threads 4 of the loom M, which makes it possible to weave a ribbon R which moves in the direction of the arrow F 3 .
  • the sickle 1 is supplied with weft thread 3 from a spool 10. Starting from the spool 10, the thread 3 passes through a fixed guide eyelet 11 and a thread brake 12 known per se which ensures the tension of the thread 3 by applying on it a constant pressure P 1 , this pressure being adjustable, as represented by the arrow F 4 .
  • the wire 3 After passing through the wire brake 12, the wire 3 runs along a return roller 14 and then comes to wind on a drum 16 belonging to a frame donor 16 whose function is to deliver to the sickle 1 a quantity of son 3 corresponding to the movements of back and forth of his free end 5.
  • the wire 3 can be in support about 180 ° on the drum 15 or do one or more rounds around this one.
  • the frame donor 16 also includes a actuator 17, for example a brushless motor, controlled by a suitable electronic unit 18.
  • the wire 3 Downstream of the drum 15, the wire 3 bears on a second roller 19 and then passes through an eyelet 20 mounted at the free end of an arm 21 movable between the two positions shown in phantom in FIG. 1, which allows to the eyelet 20 to describe a trajectory globally in an arc C 1 .
  • the position of the arm 21 is controlled by a second servomotor 22, for example a brushless motor which is powered to generate a substantially constant.
  • the thread 3 passes through a second fixed eyelet 23 then through a eyelet 6 formed at the level of the free end 5 of the sickle 1.
  • the torque C 2 exerted by the motor 22 on the arm 21 directly influences the tension T of the weft thread 3 between the eyelets 23 and 6.
  • the motor 22 is supplied so that, in taking into account the trajectory of wire 3 between the elements 19, 20 and 23, the voltage T is substantially constant, the value of this constant that can be set by the adjusting the motor power supply 22.
  • a sensor 25 is installed near the actuator 22 for detecting the angular position of its rotor ⁇ 22a.
  • the sensor 25 is connected to the unit 18 and its electrical output signal S 1 is supplied to this unit to control the servomotor 17 and thereby the drum 15, so as to deliver a quantity of weft yarn 3 which reduces Permanently the arm 21 in the desired position.
  • the drum 15 delivers the amount of weft yarn 3 just needed for the movements of the end 5 of the sickle 1.
  • the assembly formed of elements 20 to 21 constitutes a compensating device or "compensator” 27 that smooth some of the violent acceleration / deceleration to which the weft thread 3 is subjected because of movements of the sickle 1.
  • the donor 16 provides the right amount of yarn required for weaving and participates in the smoothing of the violent accelerations / decelerations of the weft yarn, since the signal S 1 makes it possible to adjust the advance of the weft thread as a function of the position of the arm 21.
  • the compensator 27 makes it possible to give a tension T substantially constant and of desired value to the weft thread in the vicinity of the sickle, this relatively independently of the position of the sickle during its movement F 2 .
  • the invention makes it possible to each moment, the speed of the donor 16 according to the need in weft yarn, so the amount of yarn provided by the donor 16 is always in line with the need for weft yarn which has, moreover, a tension T substantially constant.
  • a single servomotor 17 may be used to drive, around a same axis A-A ', several drums 15 1 to 15 n which are in number corresponding to the number of sickles 1 1 to 1 n .
  • a single servomotor 22 is, moreover, used to drive, simultaneously and around another axis B-B ', n arm 21 1 to 21 n in the eyelets 20 1 to 20 n which pass the weft son 3 1 to 3 n .
  • the torque C 2 exerted by the servomotor 22 is adjusted to take into account the number of arms 21 1 to 21 n to drive.
  • an electrical signal S 1 is used by a control unit 18 to drive the motor 17 as a function of the angular position of the motor 22 detected by a sensor 25.
  • the invention can also be implemented when each sickle is fed with several weft threads.
  • the Servomotors 17 and 22 are structurally identical.
  • the motor 22 can be replaced by a linear motor within compensator 27.
