Definitions

  • the present invention relates to a movement control mechanism back and forth of the claw frames of a training device from the crowd of a loom.
  • the invention relates more particularly, although not exclusively, to a device of the kind in question produced in the form of an armor mechanism with great length in the direction of the chain.
  • Armor mechanics of this kind are generally actuated by means of a set of connecting rods and levers from a rotating shaft in synchronism with the loom weave.
  • This tree is arranged transversely, that is to say in the direction of the weft of the fabric.
  • On the tree are wedged eccentrics or cams operating levers from which the usual levers of order of the two claw frames.
  • the levers from the mechanical control shaft are of great length, so that they are of realization not very economical due to their complexity.
  • these levers must be designed not to flame during the transmission of forces, this which requires them to have a heavy structure which harms the rapid operation of such a mechanism due to their inertia.
  • the mechanism following the preamble of the independent claim further includes two pendulums which are associated with actuation levers for claw frames, while the lever in V includes an extension in the corners of which two joints are provided for the ends of two short connecting rods whose opposite ends are respectively articulated in opposition to the two usual pendulums which control the actuation levers of the two claw frames.
  • chassis 1 of a mechanical of armor essentially comprising two claw frames 2, 3 which are moved vertically back and forth by a control mechanism according to the invention.
  • the frame 1 is placed on two beams 4, 5 located above a not shown weaving loom whose warp threads must be raised and / or lowered using the illustrated armor mechanics.
  • the control shaft of the mechanism according to the invention is arranged in the middle part of chassis 1 and it has been assigned the reference 6. This tree is controlled in rotation by the loom and we will not return not on this well known training.
  • the lever 11 has an extension 11c in duquels angles are mounted two axes 13, 14 around which are articulated respectively at one end of a connecting rod 15, 16.
  • frames 2 and 3 are animated by a vertical back and forth movement thanks to the presence of two long levers 17, 18 associated with the upper frame and by two levers short 19, 20 articulated to the lower frame 3.
  • the levers 17, 19 and 18, 20 are mounted oscillating in pairs on a balance 21, 22 which pivots around a shaft 23, 24. These two shafts are arranged symmetrically with respect to the transverse plane of the chassis 1 containing the geometric axis of the tree 6.
  • rocker 21 is provided with a flange 21a facing away frames 2 and 3, while the rocker arm 22 is provided with a flange 22a facing the frames 2 and 3.
  • Each flange 21 has , 22 a comprises a fixed axis 25, 26 around which the second end of the levers 15, 16 pivots.
  • the connecting rods 15 and 16 are relatively short, so that they do not harm rapid mechanical operation because they do not generate no difficulty in terms of their inertia, even if the length of the chassis 1 in the direction of the chain is very important.
  • the ends of the levers 17, 18, 19, 20 which cooperate with the pendulums 21 and 22 can be placed in different positions in lights 21 b , 21 c of the pendulum 21 and 22 b , 22 c of that 22 in order to adjust the stroke of frames 2 and 3.
