Definitions

  • the present invention relates to mechanics for the formation of crowd on the looms, and it aims more particularly (because it is in this case that its application seems to present the most interest), but not exclusively, those of the Jacquard type.
  • document FR-A-2 660 672 proposed to directly drive the input shaft of the mechanical using an independent motor, associated on the one hand with two encoders cooperating respectively with the aforementioned shaft and the main shaft of the trade, on the other hand to an electronic variator arranged for power the independent motor in synchronization with that of the trade based on information received from the above coders.
  • the present invention has set goals of reducing energy consumption, getting a perfect synchronization between mechanical and loom, to remove mandatory use of high definition coders and decrease the cost of the whole.
  • the training system according to the invention is defined in the claim 1
  • the mechanical input shaft is actuated on the one hand by an independent motor with variable torque controlled, not enslaved to the main tree of the trade, on the other hand by a tree of synchronization linked to the aforementioned main tree.
  • the torque control of the independent motor is operated at using an electronic variator associated with a computer arranged to properly process the information received from the controller mechanical control.
  • This calculator determines at all times the torque as a function of the elastic imbalances detected by the controller.
  • reference 1 designates the input shaft which provides the drive Jacquard mechanics shown schematically in 2.
  • This mechanics 2 is equipped with an encoder 3 which detects the angular position of tree 1 and which sends the corresponding information 4 to the controller 5 which operates the electronic reading of the armor program introduced in said controller, in order to send the armor information 6 to the mechanics 2.
  • the controller 5 sends angular position information 7 and armor information 8 to a computer 9 whose arrangement functional was illustrated in fig. 2.
  • Information 13 (imbalance torque), 14 (inertia torque) and 15 (constant pairs) respectively emitted by modules 10, 11 and 12 of the computer 9 are sent to an electronic adder 16 at level at which they are tabulated to define information 17 corresponding to the resulting torque.
  • This information 17 is sent to the variator 18 of an independent motor 19 (fig. 1) equipped with an automatic brake 19 ', which motor 19 drives the input shaft 1 of the mechanism 2.
  • the shaft 1 is provided with a conical couple 20 ensuring its connection with a vertical synchronization shaft 21, the base of which is itself connected by another conical couple 22 to the main shaft 23 which ensures loom training 24.
  • the input shaft 1 of the mechanics 2 is consequently driven by two separate motor sources 19 and 23, the respective values of couples exerted on said shaft 1 by these two sources varying at all moment depending on the resulting torque 17.
  • Fig. 4 shows in gray the part of the torque provided by the motor 19, clearly the small part of the torque transmitted by the shaft of synchronization 21.
  • system according to the invention is capable of being applied to the mechanics of the dobby kind by incorporation an appropriate controller.
