Definitions

  • the present invention relates to Jacquard mechanics for training the crowd on weaving machines and it relates more particularly to those in which the reciprocating hooks which actuate the arches of the usual harness are controlled by knives carried by the parallel strands of '' a series of funicular organs or belts arranged in pairs.
  • the movement is taken from the main shaft of the weaving machine using a first bevel gear connected by a vertical shaft to a second bevel gear provided the height of the mechanics to be driven.
  • the horizontal output shaft of this second reference constitutes the input shaft of the mechanics, on which are generally generally mounted a modulator device capable of conferring on said shaft the desired law of movement for mechanics, a device for research pitch (untwisting) and a brake intended to automatically immobilize the mechanics as soon as the drive stops.
  • the mechanical input shaft must obviously be connected to the drums which provide the alternating drive for each of the knife-carrying belts, and on this point we can refer to what has been described and represented in French Patent N ° 2 703 697 (STAUBLI).
  • the input shaft carries two eccentrics for the control of two vertical connecting rods which actuate themselves two horizontal connecting rods linked to the pairs of drums, these being established at different diameters which are decreasing by one end to end of the mechanics in order to give knives and hooks different strokes specific to obtaining an oblique crowd.
  • the present invention intends to remedy, which essentially consists in driving each of the shafts which carry the drums associated with the pulleys of the same pair of belts, using an independent electric motor which is powered. through an electronic variator for the cyclic reversal of the direction of rotation and to which is directly integrated an angular marking encoder.
  • Each of the mechanical encoders is connected to an electronic comparator which receives the signals from an angular encoder linked to the shaft of the weaving machine and which sends the instructions to the above-mentioned variators ensuring the correct angular setting of the mechanics by compared to the aforementioned machine.
  • Fig. 1 is a plan view from above of a Jacquard mechanism established in accordance with the invention.
  • Fig. 2 is a partial cross section on a large scale along the plane indicated in II-II in FIG. 1.
  • Fig. 3 is a diagram illustrating the electronic supply of the motors.
  • the frame of the Jacquard mechanism as shown in fig. 1 and 2 is formed by two vertical flanges which have been referenced 1 in FIG. 2. It is between these two flanges 1 that the different vertical rows of modules 2 are mounted, enclosing the members (lifting beam, electromagnet, hauling, etc.) associated with the reciprocating hooks (shown diagrammatically in 2 a in fig. 2) controlled by horizontal knives 3 to actuate the harness arches of the mechanics considered. Between the adjacent rows of modules 2 are mounted horizontal shafts 4 oriented perpendicular to the abovementioned flanges 1.
  • each shaft 4 the top of each of the flanges 1 is provided with a console 5 forming a support for two bearings 6 ensuring the mounting of the ends of a horizontal drum 7 for driving a vertical belt 8; the pair of belts 8 associated with the same shaft 4 supports by one of the strands two knives 3 arranged at heights suitable for acting on the two hooks of all the modules 2 of the same row.
  • tubular hub of one of the drums 7 (the one on the left in fig. 2) is directly engaged the corresponding end of the shaft 4 envisaged, the angular connection between the shaft and the drum being ensured by a flange of pinching 9.
  • the opposite end of the shaft 2 is engaged and pinched in the corresponding end of the other drum 7, the opposite end of the latter receiving the shaft 10 of an electric motor 11 fixed laterally against the console 5; the angular connection between the shaft 10 and the corresponding drum 7 is here also effected by means of a clamping flange 9.
  • the motors 11 are of the synchronous self-piloting type ("brushless") and each of them incorporates an automatic brake 18 and an angular encoder 14.
  • FIG. 3 clearly shows the electrical and electronic diagram for supplying these motors.
  • An electronic variator 12 is provided on the electrical supply conductors of each motor 11 which ensures the cyclic reversal of the direction of rotation of the shaft 10.
  • This variator 12 is placed under the control of an autonomous electronic comparator 13 which receives the signals coming from the angular encoder 14 integrated into the motor 11 envisaged, in order to compare them with those coming from an encoder 15 associated with the drive shaft of the weaving machine MT in order to permanently detect the angular position of said shaft .
  • the signals are processed on the one hand by a common electronic cam 16 for the transformation of the signals of continuous rotation into signals of alternative rotation, on the other hand by a independent amplifier 17 able to assign to the motor 11 which corresponds to it the coefficient amplification of the length of the alternative movement of movement of the two belts 8 as a function of the position of the shaft 4 along the mechanics (obtaining an oblique crowd).
  • each shaft 4 overcomes the drawbacks mentioned above. It will also be noted that the modification of the obliquity of the crowd is effected by means of a simple intervention at the level of the amplifiers 17, while in conventional Jacquard mechanics with central drive derived from the motor of the weaving machine, this same modification constitutes a very complex operation, involving the change of a series of mechanical components and delicate adjustments.
