Definitions

  • the invention relates to a method and a device for positioning warp threads and to a loom equipped with such a device.
  • a device is known from document EP-A-0 353 005.
  • the invention intends to remedy more particularly by proposing a device for positioning the warp yarns which can be used automatically, with precision and reproducibility greatly improved compared to known techniques.
  • the invention relates to a device for positioning warp threads in a weaving loom, controlled for the formation of the crowd by electric actuators, which comprises a first means, common to the threads driven by different actuators, of detection of the passage of at least one warp thread in a determined position and a second means for determining the value of a control parameter of the corresponding actuator during the passage of a thread in this position.
  • the invention it is possible to move a warp thread or a group of warp threads by activating an actuator up to a predetermined position, which can be checked using the first means, while the second means makes it possible to acquire a value of an actuator control parameter which can then be used as a reference value for controlling the this actuator.
  • the first means is a detection assembly fixed to a frame of the loom and comprising a source for transmitting a wave signal and a cell arranged opposite this source by relative to the warp threads and capable of detecting a variation in the wave signal.
  • this source can be an emitter of a laser beam, while the cell is capable of detecting a variation in the intensity of this beam which occurs when one of the chain wires interferes with the laser beam.
  • the first means comprises a filiform sensor arranged in a direction parallel to the weft threads of the loom.
  • the first means comprises a carriage movable along a support extending in a direction generally parallel to the weft threads of the loom, this carriage being equipped with a contact sensor capable of cooperating selectively with one of the warp threads.
  • the carriage can be integral with an extension capable of coming into contact with certain warp threads in the trade, the contacts between these warp threads and this extension making it possible to generate a force for moving the carriage on the support.
  • the invention also relates to a weaving loom comprising a device as previously described.
  • a weaving loom operates more safely and more precisely than the known looms, while its installation and maintenance are greatly simplified.
  • This process has the advantage of being automated and of allowing the heddle travel of a loom to be adjusted by programming the electric actuator associated with each heald or group of heddles without manual intervention on the arches.
  • any misalignment between the beams and yokes can be compensated for by controlling the electric actuator from the value selected as the reference value which corresponds to the same position for the different warp threads.
  • the method consists in using the selected value of the parameter for the determination of at least one set value of the parameter corresponding to at least one particular position of the movement of the wire generated by the actuator. Thanks to this aspect of the invention, the selected value makes it possible to precisely position the warp threads throughout their trajectory.
  • the method is applicable when several warp threads are moved by means of a single actuator, which is the case in a loom equipped with a dobby or in a Jacquard type loom with several patterns repeated across the width of the fabric.
  • the passage of at least one of the warp threads driven by the actuator is detected in the determined position and the selected value of the parameter is used to control the actuator.
  • the first wire reaching the predetermined position and the last wire reaching this position can be detected, two values of the actuator control parameter being selected. and used by a control unit to control the actuator, the first value being able to be used for the determination of the bottom dead center of the corresponding stroke, the second value being used for the determination of the top dead center.
  • the weaving loom shown diagrammatically in FIG. 1 comprises warp threads 1 each passing through an eyelet 2 of a heddle 3 driven by a vertical oscillation movement represented by the arrow F 1 generally perpendicular to the direction of movement of the threads weft represented by arrow F 2 .
  • Each stringer 3 is connected by a cord 4 to a pulley 5 driven in rotation by an electric servomotor 6.
  • each stringer 3 is connected by a rod 7 to a spring 8 secured to the frame 9 of the loom.
  • each motor is controlled by a control unit 10 which delivers to the motor 6 a control instruction corresponding to given angular positions of the motor.
  • Each position may be defined by a parameter ⁇ representative of the instantaneous angular position of rotation of the shaft 6a of the motor 6, the motor control is performed using the parameter ⁇ as a desired value.
  • a detector 11 installed at the rear of each motor 6 is provided to cooperate with a cup 12 driven in rotation by the shaft 6 a .
  • the encoder formed of the elements 11 and 12 makes it possible to produce a position control, for precise control of the motor 6, by virtue of a signal S 1 which it addresses to the unit 10 by an electrical connection 13.
  • a laser 20 is placed opposite a target 21, so that the light beam 22 which it emits is generally parallel to the direction F 2 of the weft yarns 24.
  • the target 21 constitutes a sensor capable of detecting a variation intensity of the beam 22 when this beam interferes with one of the chain wires 1. Under these conditions, the cell 21 sends to the unit 10, through an electrical connection 14, a signal S 2 signifying that the wire of chain 1 in question is in the position of interference with the beam 22.
  • the positioning process consists first of all in removing all the warp threads from the bundle 22, by bringing them above or below the latter. Then, each wire 1 is successively moved in the direction of the bundle 22 until the assembly formed of the elements 20 and 21 detects that the corresponding warp thread 1 is in the position of intersection of the bundle 22. During the interference between a wire 1 and the bundle 22, the unit 10 stores the set value ⁇ 0 of the parameter ⁇ which corresponds to this position for the corresponding actuator 6.
  • P 0 denotes the position of the eyelet 2 of a heddle 3 when the wire passing through this eyelet reaches the bundle 22.
  • the position P 0 corresponds to the value ⁇ 0 of the parameter ⁇ for controlling the motor 6. This value ⁇ 0 can therefore be considered as corresponding to a reference position of the movement of the wire 1.
  • the means for detecting the position of the warp threads can comprise a linear capacitive sensor disposed in the direction F 2 of the weft son 24 of the loom.
  • Any light source can be used for the present invention, provided that a suitable cell is used. Satisfactory results have been obtained with a gas laser of the helium-neon type and with a diode laser, which are commercial products whose cost is well controlled.
  • FIG. 2 elements similar to those of the first embodiment bear identical references increased by 50.
  • a heald 53 for controlling the vertical displacement F 1 of a warp thread 51 through an eyelet 52 has been shown.
  • This heddle is associated with a cord 54 intended to be wound on a pulley 55, this pulley being controlled in rotation R by a servomotor 56.
  • a rod 57 connects the heald 53 to a spring 58 secured to the frame 59 of the job.
  • a unit 60 for controlling the motor 56 makes it possible to control, this motor in position as a function of set values ⁇ corresponding to each of its positions of its shaft 56 a .
  • a wire 70 is stretched, parallel to the direction F 2 of the weft threads 74, between two parts of the frame of the loom and it constitutes a sensor for the arrival of a warp thread 51 at its height because the contact between the threads 51 and 70 generate vibrations which can be detected by a piezoelectric cell 71 connected by an electric line 64 to the unit 60.
  • the wire 70 may not be stretched between the two parts of the frame, in which case its exact geometry is taken into account to compensate for the differences in height of the positions detected.
  • the cell 71 which transmits, by an electric line 64, a signal S 2 to the unit 60.
  • the unit 60 selects the instantaneous set value ⁇ 0 of the control parameter ⁇ as a reference value for determining the trajectory of the boom 53. As previously, this value can be used as a basis for determining, by calculation, all the positions of the boom 53 and the associated wire 51.
  • the warp threads 101 of a weaving loom are provided to be moved by heddles 103 of which they pass through the eyelets 102.
  • a beam 175 is arranged above the warp threads, parallel to the direction F 2 of the weft threads and in front of the loom harness, this beam being in abutment on the frame 176 of the trade.
  • a carriage 177 is movable in translation along the beam 175 and is fitted with rollers 178 allowing it to move without excessive friction along the beam 175.
  • the carriage 177 carries a tongue 170 associated with two studs 171 and 171 ' that it makes it possible to connect electrically when a warp wire 101 comes to bear against its lower surface.
  • the method of the invention consists in placing the carriage 177 successively above each chain wire and in raising this chain wire until it exerts on the tongue 170 a sufficient force to close the electrical circuit which comprises pads 171 and 171 ', which has the effect of transmitting, through an electrical connection 114, a signal S 2 , corresponding to this detection, to a unit 110 of the type of unit 10 of the first embodiment. This signal S 2 is then processed as in the first and second embodiments.
  • the carriage 177 is equipped with an extension 182 intended to cooperate with warp threads other than the one whose displacement is to be measured.
  • This extension 182 is provided with two surfaces 182 a and 182 b forming, for one, a ramp and, for the other, a stop as shown in the explanations which follow.
  • a second group of warp yarns 101 '' is also lifted so that it forms a stop for the advance movement of the extension 182 under the effect of the forces F 3 by pressing the surface 182 b against them- same.
  • the wires 101 '' are lowered and a new group of wires 101 'is raised.
  • extension 182 can be adapted as a function of the direction of movement of the carriage 177.
  • the invention is also applicable to the case where a single actuator makes it possible to move several heddles, for example in the case of a loom of the Jacquard type intended to form a fabric with repetitive patterns across the width.
  • the precision obtained is less, because the heddles associated with a single actuator are not adjusted between them.
  • These healds are adjusted in groups between the different actuators by detecting, for example, the position of the highest warp thread and the position of the lowest warp thread when they successively reach a predetermined position from a position low. In this case, two values of the actuator control parameter are selected, these values each corresponding to the first or the last wire reaching this position.
  • the value selected for the first wire is used to determine the bottom dead center of the heald beam path associated with the actuator because this position determines the internal envelope of the crowd in the low position.
  • the value of the parameter selected for the last wire reaching the predetermined position on the ascent is used to determine the top dead center position of the heddles associated with this group of wires, since this position is determined by the low envelope of the high crowd. This process therefore makes it possible to obtain an optimized opening of the crowd, including in the case of the control of several wires with a single actuator.
  • a control loop is created between the means 20, 21, 70, 71, 170 or 171, for detecting the position of the warp threads and the means 10, 60 or 110, for actuator control. This loop makes it possible to control the movement of the warp threads with great precision.
  • the transmission of the signal S 2 to the control unit 10, 60, 110 or equivalent can take place by a link other than an electric wire, provided that it intervenes in time real.
  • the detection means, 20, 21 or equivalent can be removably mounted on the loom and, in particular, be dismantled after equalization in order to be used on other looms .
  • the invention is applicable to weaving looms equipped with electric actuators controlled in open or closed loop, rotary or linear.
  • the positioning of a loom harness can be carried out automatically and with great precision, so that the heddle travel can be optimized by reducing the difference between the high positions P 1 and low P 2 of their stroke, that is to say the opening of the crowd, so that a loom incorporating a device as described above can operate at very high speed and with better efficiency.
  • the invention is also applicable to looms equipped with dobby, the detection of the movement of the warp threads associated with a frame then being made in one operation, as in the case of a Jacquard loom with multiple patterns.
