Definitions

  • the present invention relates to a device for adjusting the positioning of yarn drafting rollers, applicable to spinning machines, which achieves considerable improvements with respect to devices currently known in the art.
  • Devices for guiding elastic yarns or filaments in spinning machines are known in this field of the art, for example the device corresponding to Spanish Utility Model 9201019 of the present Applicant, intended to guide a elastic yarn up to the pair of delivery cylinders of a spinning machine and comprising rocker arms for carrying the upper rollers of the draw-frames, which is characterised by arrangement at the end of the rocker arm of a head for carrying the guide rollers for the elastic yarns, which is capable of displacement along its vertical axis, in a pendulum-like manner, carrying in a floating manner the axle for carrying the guide rollers for the elastic yarns.
  • Said rollers are provided with resilient O-rings coupled at their peripheries to establish direct contact with the lower rollers of the pairs of corresponding drafting rollers.
  • the present invention relates to a device which has the same object as that mentioned in said Spanish Utility Model, but comprises substantial improvements with respect thereto. Said improvements relate to the method of achieving the adjustment in the positioning of the yarn drafting rollers.
  • the object of the present invention is, in particular, to achieve the means for obtaining a possibility of grading which is much more extensive and efficient than in the currently known devices.
  • the present invention provides a support arm for the pair of yarn guide rollers which comprises a large central aperture for lateral displacement of the axle support for carrying the rollers, the axle support being fixed in position by means of the combination of a grooved face produced in a part joined to the rocker arm and a further mating grooved part arranged so as to oppose it, which is the carrier for a support rod for the axle equipped with the rollers.
  • a support arm for the pair of yarn guide rollers which comprises a large central aperture for lateral displacement of the axle support for carrying the rollers, the axle support being fixed in position by means of the combination of a grooved face produced in a part joined to the rocker arm and a further mating grooved part arranged so as to oppose it, which is the carrier for a support rod for the axle equipped with the rollers.
  • the grooved part carrying the roller assembly is fixed by a quick-action system, for example an eccentric device, such that the adjustment possibilities are extensively increased and the resulting adjustment operation is very simple and quick.
  • the upper carrier part for the roller assembly and the lower part associated with the rocker arm can carry reference markings which facilitate the adjustment task and possible reproduction thereof.
  • Fig. 1 shows a lateral elevation in section, in the sectional plane indicated, of a device produced in accordance with the present invention.
  • Fig. 2 shows a plan view of the device.
  • Fig. 3 shows a detail in section in the sectional plane indicated.
  • Figs. 4, 5, 6 and 7 show details of the part associated with the rocker arm, in sections along the sectional plane indicated, a plan view and an elevation respectively.
  • Figs. 8, 9 and 10 represent details of the upper supporting part of the rollers, a front elevation, longitudinal section and plan view respectively.
  • the device according to the present invention is coupled to the rocker arm 1 carrying the rollers 2 and 3 for guiding the yarns in their respective grooves 4 and 5, and has a part 6 coupled to the end of said arm 1, for example by threading the end of said arm in grooves of the aforementioned part and transverse fixing nuts and bolts 7 or another similar mechanism, said part 6 having a large orifice 8, Fig. 3, traversed by the roller carrying axle 9, and also having an upper transverse opening 10, in the form of a slot, along which the rod 11 associated with a part 12 carrying the roller axle 9 can be displaced.
  • the part 12 is secured to the rod 11 which goes through an upper part 13 capable of displacement along the groove 10 to achieve the desired adjustment positions for the rollers 2 and 3.
  • the parts 6 and 13 each have mating groovings at their opposing faces, as represented in Figs. 4 to 8 where it can be seen that the part 6 has grooving 14 in its upper face into which meshes a grooving 15 of the lower face of the part 13.
  • the transverse position of the rollers is changed with respect to the arm 1 by varying the coupling grooves between said parts.
  • the part 13 is fixed in its operating position by means of any device known in the art, for example an eccentric device 15, on which there acts a spring 16 supported at the bottom by means of an adjustable plug 17.
  • the device according to the present invention comprises some characteristics of notable simplicity and functional efficiency. In effect, it is sufficient to loosen the eccentric device 15 to allow the part 13 to be displaced to the desired position, possibly with the aid of the adjustment marks 18 of the part 13 and possibly of the part 6, then to go back and tighten the eccentric 15 so that the new adjustment position is properly fixed.
  • said upper part has a collar 18 at the bottom, which is adjusted in a sliding manner in the interior of the groove 10, allowing its transverse displacement with respect to the arm 1 but not allowing axial displacement thereof.
