Definitions

  • a thread-guiding assembly for a bobbin-winding machine has a reciprocating carriage with a guide rod or sleeve slidably supporting a shoe which contacts the peripheral surface of a coil wound on a bobbin, the guide rod or sleeve being parallel to the nearest generatrix of a conical (or, in a limiting case, flat) face of the bobbin base whereby a thread passing through an orifice on the shoe is wound into a coil with either tapered or flat ends.
  • This invention relates to thread guides for bobbinwinding machines.
  • a thread guide for bobbinwinding machines suitable for the production of crosswound or parallel-wound bobbins whose coils or thread packages have either tapered or flat ends, and which comprises a thread-guide support, arrnged to be driven in a reciprocating manner parallel to the longitudinal axis of a bobbin to be wound, and a thread-guide element arranged on the thread-guide support and incorporating a thread eyelet, wherein an axial shift of the thread-deposition stroke corresponding to the desired slope of the edge of the coil to be wound on the bobbin occurs in dependence on increasing coil diameter.
  • thread guide of the abovementioned type for a bobbin-winding machine the threadguide element is fixedly secured to the thread-guide sup port, with the result that both members execute not only the reciprocating movement necessary for the deposition or winding of the thread on the bobbin but also the additional axial displacement necessary for obtaining the desired slope of the edge of the coil to be wound on the bobbin.
  • the axial displacement is effected by means of a comparatively complicated control system which can be suitably adjusted.
  • the thread-guide element is displaceably mounted on guide means extending parallel to the desired end surface and including a slide shoe by means of which it is slidingly displaceable on the surface of the coil wound on the bobbin.
  • the slide shoe which preferably contains the thread-guide eyelet controls itself, as it were, by its permanent engagement with the surface of the coil wound on the bobbin, since with increasing diameter of the coil the shoe undergoes an additional axial displacement corresponding to the desired slope of the end of the coil or thread package wound on the bobbin, in consequence of *which the thread-deposition stroke arising from the reciprocating movement of the thread-guide support, the
  • the advantage of the invention for bobbin wound with flat-topped coils is that the thread guide moves outwardly linearly with increasing coil diameter and does not describe an arcuate path which would cause the angle between the threadguide and the bobbin to change by too large an amount. If the thread-guide is moved radially in an axial plane of the bobbin, then the thread-winding angle remains constant over the entire length of the bobbin.
  • the thread-guide element includes a slide member carrying the slide shoe which in turn contains the thread-guide eyelet, the slide member being displaceable on a guide rod in opposition to the action of spring means arranged on the guide rod.
  • the slide member is preferably held permanently by a coil spring located on the guide rod in a position in which the slide shoe rests against the coil wound on the bobbin. It has been proved that the quality of bobbins wound in this manner is improved, since on account of the reciprocating sliding movement of the slide shoe over the surface of the coil wound on the bobbin an ironing effect takes place which results in a corresponding smoothing of the wound coil.
  • the guide rod or rods may be arranged to be unadjustable after being initially set at the angle of inclination required for the desired slope of the end surface.
  • the guide rods may be mounted for pivotal adjustment about an axis extending transversely to the longitudinal axis of the bobbin, in order that they can easily be adapted to the production of bobbins with different slopes of their end surfaces.
  • the slide shoes preferably have a bearing or support surface which is rounded to correspond to the range of said pivotal adjustment.
  • the guide means comprises a pair of guide rods for each slide member mounted for pivotal movement on opposite sides of a carrier arm resting on the thread-guide support, the free upper ends of the guide rods being adjustably secured in slot guides provided in a curved retaining member which extends concentrically about the pivotal axis of said guide rods.
  • the slide shoe which contains the thread-guide eyelet is arranged rigidly on the thread-guide element, the slide shoe always describes the same path of movement as the thread-guide element.
  • This is sometimes, however, disadvantageous, since the guidance of the slide shoe on the coil wound on the bobbin in the region of the edge of the coil is uncertain, especially when working with fine thread materials, particularly with synthetic yarn.
  • This disadvantage can, however, be reliably overcome in a comparatively simple manner by arranging, according to a further feature of the invention, that the slide shoe is displaceably mounted on an extension of the thread guide element for limited displacement parallel to the longitudinal axis of the bobbin.
  • the slide shoe may under these circumstances be formed in a different manner.
  • it may consist of a U-section member or yoke having its arms extending upwards one on each side of the guide extension, one of said arms having a guide slot formed therein to receive two guide pins extending laterally from the extension, and the base of the U-section member having an open-ended slot formed therein for the thread emerging from the thread-guide eyelet in that extension.
  • a stationary stop member having a stop surface extending parallel to the edge of the coil to be wound on the bobbin may be arranged at the end of the bobbin remote from the foot thereof for engagement by the yoke member at one end of its path of movement. This ensures that the stop surface provided on the stop member always displaces the slide shoe in the direction of the coil, independently of the particular diameter of the coil, by a fixed amount relative to the thread-guide extension containing the thread-guide eyelet, in consequence of which an adequate support of the slide shoe on the coil is ensured.
  • the slide shoe may alternatively consist of a slide tongue mounted for limited displacement in a longitudinal slot formed in the thread-guide extension, the tongue :being urged by a spring mounted on the extension into a position where it extends beyond the forward end of that extension containing the thread-guide eyelet.
  • a special stop member for the displacement of the slide tongue is not required. Its displacement occurs, on the contrary, only in the position of thread-guide reversal at the foot of the bobbin, where the slide tongue strikes against the conical foot of the bobbin and thereby lags relative to the projecting extension.
  • a spring is arranged to urge the shoe of the thread-guide element against the surface of the coil wound on the bobbin, the spring acting on the thread-guide element through a lever having a variable effective length so that the pressure of the slide shoe on the coil remains constant, or is even reduced, with increasing diameter of the coil.
  • FIGS. 1 and 2 show, respectively, a front elevation and a side elevation of a first embodiment of a thread guide in accordance with the invention for use in the winding of a coil on a bobbin having a conical end plate, the coil having a tapered head with an edge sloping at an angle of about 45;

  • the slide blocks 12 and 13 are subject to a downward force exerted by coil springs 19 located on the guide rods 8 and 9 and thus hold the slide shoes 16 and 17 carried by the slide blocks in constant contact with the peripheral surfaces of the coils 20 wound on the two bobbins located at the winding station.
