Definitions

  • the invention relates to a Jacquard type weave mechanism and to a loom equipped with such a mechanism.
  • the invention also relates to methods of assembling and dismantling such a mechanism.
  • the invention more particularly intends to meet by proposing a weave mechanism in which the mounting of the various winding pulleys can be carried out in a convenient and fast manner.
  • the invention relates to a Jacquard type armor mechanism for forming the crowd on a loom, this mechanism comprising several electric rotary actuators adapted to each rotate a winding pulley of a funicular element for controlling the position of at least one rail, while a cover is provided to isolate outside and / or protect a group of pulleys mounted on neighboring actuators.
  • This mechanism is characterized in that this cover is provided with means for retaining at least one pulley in a position allowing its mounting on the corresponding actuator or its disassembly relative thereto.
  • the establishment of the cover facing the actuators, in particular on a housing in which actuators are mounted allows simultaneous implementation of the pulleys or it carries.
  • the invention also relates to a loom equipped with a weave mechanism as previously described.
  • a loom is more economical, easy to install and maintain than those of the state of the art.
  • the establishment of the cover relative to the actuators allows both to secure the pulleys and actuators and release these pulleys to allow their rotation without friction on the cover.
  • the securing of the pulley and the corresponding shaft advantageously takes place by snapping.
  • the loom M represented at figure 1 comprises a mechanism formed by the mutual assembly of a multitude of housings 1 each of which contains sixteen electric rotary actuators 2 whose output shaft 3 can carry a pulley 4 for winding an arch 5 connected to a rail 6 intended to to order a warp thread 7 of the trade M and associated with a return spring 8 in the low position.
  • the different housings are assembled in rows perpendicular to the plane of the figure 1 and in columns parallel to this plane. They form two panels A and B arranged above the weaving area. Alternatively, a single panel formed of housings 1 may be provided. Alternatively also the panels A and B may be generally vertical and parallel to each other.
  • each housing 1 contains sixteen actuators 2 whose respective output shafts 3 are parallel and protrude from the front face 11 of the housing 1.
  • Each pulley 4 defines a volume 41 for receiving and wedging elastic tabs 31 provided at the end of each shaft 3, which allows an elastic snap of a pulley 4 on a shaft 3 (see FIG. figure 6 ).
  • a cover 20 is provided to be mounted on the front face 11 of the housing 1 together with a bar 21 for guiding the arches 5.
  • the cover 20 is configured to hold in position the sixteen pulleys 4 intended to be mounted on the actuators 2 of the housing 1.
  • the cover 20 forms several zones 22 in which the pulleys 4 may be snapped.
  • Each zone 22 is bordered by an elastically deformable tab 23a and by a rigid abutment 23b each provided with a bead 24 oriented towards the center of the zone 22.
  • Each pulley 4 is provided, at a collar 42 of larger diameter, with two recesses 43 of shapes corresponding to those of the beads 24.
  • zones 25 forming recessed recesses of slightly greater diameter than those of the collars 42 are provided, which allows the pulleys 4 to be partially engaged in these recesses without being in contact with the cover 20.
  • the lid 20 is also provided with stiffening ribs 26 which define individual compartments adapted to each receive a pulley, these compartments communicating with each other to allow the passage of the arches 5.
  • the pulleys 4 are mounted on the cover 20 by moving each pulley towards a zone 25, as represented by the arrow F 2 at the figure 3 , which makes it possible to reach the position represented in the upper right part of this figure. It is then sufficient to exert a vertical force directed downwards on the pulley 4, as represented by the arrow F 4 , to reach the position of the pulley represented in the lower right corner of the figure 3 where the tab 23a has been deformed elastically to allow insertion between it and the abutment 23b of the flange 42. The beads 24 then engage in the recesses 43, which allows immobilization of each pulley 4 relative to the cover 20 in a vertical direction.
  • the lug 23 a is integral with a tongue 28 defined between two slots 29 a and 29 b, which allows a deformation of the elements 23 a and 28 in the direction of arrow F 6 to the figure 4 , thus allowing the introduction of the pulley 4 in the zone 22.
  • the tab 23 a and tab 28 working in flexion during the opening movement of the pulleys 4 in the zones 22 and during the extraction movement.
  • the two elements 23 a and 23 b may be deformable relative to the rest of the cover 20.
  • the zone 22 is also bordered by a tooth 22b whose shape corresponds approximately to that of a cutout 45 formed in the flange 42.
  • the cooperation of the elements 22b and 45 makes it possible to control the angular orientation of the pulleys 4 around their respective central axes X 4 -X ' 4 after mounting on the cover 20.
  • the pulleys 4 mounted on the cover 20 may all be substantially in the same angular position around their respective central axes X 4 -X'4.
  • the cover 20 There are provided on the cover 20 as many retention zones 22 as there are actuators 2 in the housing 1. The zones are distributed according to the distribution of the actuators in the housing.
  • the spatial organization of the pulleys 4 previously mounted on the cover 20 is in exact correspondence with the spatial organization of the actuators 2 in the housing.
  • the assembly formed of the elements 20 and 21 is then plated on the face 11 of the housing 1 as in the direction of the arrow F 10 at the Figure 2A , that is to say in a direction generally parallel to the central axes X 3 -X ' 3 of the shafts 3.
  • the direction of translation of the cover 20 relative to the housing 1 is also parallel to the axes X 4 -X' 4 of pulleys 4.
  • the establishment of the cover 20 and the bar 21 on the housing it allows, particularly easily, the simultaneous engagement of the pulleys 4 on the different actuators 2 and their simultaneous release relative to the cover 20.
  • the cover 20 is animated with a vertical upward movement represented by the arrow F '11 to the Figure 2C , which allows to reach again the configuration of the Figure 2B , the different pulleys 4 being again engaged in the zones 22 by this movement.
  • the pulleys 4 are then subjected to a tensile force F 12 transmitted by the arches 5 and resulting from the action of the return springs 8, which contributes to their angular orientation, each around its axis X 4 -X ' 4 .
  • the pulleys are then immobilized in rotation by the cooperation of the elements 24 and 43 which engage.
  • the effort F 12 thus makes it possible to obtain a leveling of the angular position of the pulleys 4 at the beginning of the dismantling, all the pulleys then having the same angular position.
