Definitions

  • ABSTRACT Bobbin support chuck with a thread severing zone defined by a thread severing ring and a thread inserting ring.
  • the thread severing ring has a ring-shaped arrangement of cutting elements on its face.
  • the present invention relates to a new and improved construction of bobbin support chuck or mandrel provided with a thread separating zone containing a thread separating ring arranged 'concentrically'with, and at the face side of, the tube, such as for example used on winding devices for endless filaments or threads equipped with automatic bobbin change devices.
  • Winding devices for endless filaments or threads equipped with automatic bobbin change devices are already known in the art wherein two bobbin tubes or sleeves alternatingly take up the thread delivered at high speed and, as the desired bobbin diameter is reached, are moved from a winding position into an idle position, the thread simultaneously being transferred to the empty tube.
  • the thread transfer is effected in that the thread, partially surrounding or wrapped about a thread separating ring and not being traversed during the thread transfer, owing to axial displacement of the bobbin chuck or mandrel is caught or seized by appropriate means, severed and wound onto the tube with a number of reserve wraps being formed.
  • the disadvantage of such devices resides in the fact that the boundary or limiting surfaces of the thread catching zone, formed by the end faces of the teeth and by the tube end face, and which boundary-surfaces extend parallel and at right angles with respect to the axis, as well as the cone tapering towards the outside within the ring arrangement of teeth, do not guide the thread with sufficient reliability into the cutting zone of the teeth. Severing'of the thread is thus not positively ensured, which can result in undesirable disturbances during the thread transfer operation.
  • Another object of the present invention relates to an improved construction of bobbin support chuck which is relatively simple in design, economical to manufacture, and ensures for positive guiding of a thread to be severed into the operable zone of cutting elements.
  • Another object of the present invention relates to an improved bobbin support chuck which is provided with means so that after severing of the thread winding of the infed thread is carried out properly and there is ensured for reliable and positive start-up of winding of the bobbin or package.
  • the invention contemplatesthe provision of a new and improved chuck or mandrel for a bobbin tube serving as bobbin support which comprises a thread severing or cutting zone embodying a thread severing or separation ring arranged concentrically with respect to the chuck.
  • This thread severing ring is provided with a substantially ring-shaped arrangement of cutting elements at one face thereof.
  • a thread inserting ring is provided between the end face of the bobbin tube and the thread severing ring.
  • This thread inserting ring possesses a substantially conical thread guide surface which extends at least partially beneath the cutting elements when the bobbin tube is placed entirely on the chuck, and at which location there are also provided thread clamping means.
  • the thread inserting ring can be moved away from the thread severing ring to facilitate removal of thread wraps which may possibly be located therebetween.
  • FIG. 1 is afragmentary longitudinal sectional view of a bobbin chuck or mandrel equipped with a bobbin tube;
  • FIG. 3 illustrates the arrangement of FIG. 1 with the bobbin tube removed
  • FIG. 4 is a fragmentary longitudinal sectional view of a further embodiment of bobbin chuck with a bobbin tube mounted thereat;
  • FIGS. 6, 7 and 8 respectively show variant constructional embodiments of the thread inserting ring and thread severing ring
  • FIG. 9 is a fragmentary sectional view of a modified form of thread inserting ring having nose-shaped projections.
  • FIG. 10 is an end view of the thread inserting ring depicted in FIG. 9.
  • FIG. 1 there is shown an exemplary embodiment of bobbin support chuck or mandrel 50 embodying a bobbin chuck shaft 1 at which there is supported by anti-friction bearing means 3 a bobbin chuck sleeve 2.
  • a thread severing or separation ring 4 is rigidly connected with the bobbin chuck sleeve 2 by means of a pin 5 or any other suitable fastening expedient
  • a thread inserting or insertion ring 6 is movably arranged upon a sliding surface 7 provided at the bobbin chuck sleeve 2 between the thread severing ring 4 and a stop member 8 likewise provided at such chuck sleeve.
  • the thread inserting ring 6 is provided with a cylindrical rim or collar 9 and a stop member or shoulder 9 for taking up a bobbin tube 10.
  • the thread inserting ring 6 further possesses a conical surface 11 which contacts or abuts against the thread severing ring 4 by means of a small end face 11' when the bobbin tube 10 is placed entirely upon the bobbin chuck or mandrel 50.
  • the thread severing ring 4 on its end face confronting the conical surface 1 l, is provided with a substantially ring-shaped arrangement of .aseries of tooth-shaped cutting elements 12. These cutting elements 12 are located at the region of the thread severing zone defined between the thread severing ring 4 and the thread inserting ring 6, and furthermore, will be seen to partially protrude into the region of the conical surface 11. Moreover, as best seen by referring to FIG.
  • each of these tooth-shaped cutting elements 12 embodies an inclined surface 13.
  • the thread severing ring 4 is also provided with a ring-shaped groove 16 into which is placed a rubber ring 19 of, for instance, circular cross-section.
  • This elastic ring-shaped member 19 is pressed'against a contacting surface and which is defined by the confronting situated conical surface 11 of the thread inserting ring 6.
  • FIG. 2 illustrates in an enlarged fragmentary view details of the thread severing ring 4 with one of the toothshaped cutting elements 12 which, as will be recalled, has an inclined surface 13. There is also depicted therein a thread F, indicated by a dash-dot line, which is, entrained or caught by such cutting element 12 and in the process of being severed.
  • FIG. 3 illustrates the bobbin chuck or mandrel 50 of the arrangement of FIG. 1 following the time where the bobbin tube 10 has been doffed, in which case the thread inserting ring 6 has been moved towards the right and contacts against the stop member 8 as shown.
