Definitions

  • the invention relates to a thread storage and delivery device according to the preamble of the main claim.
  • the object of the invention is based on the design of a generic thread storage and delivery device in a technically simple manner in such a way that, with a high thread throughput, an orderly large thread supply can be stored, in particular with a wide variety of threads, in particular elastic threads.
  • a thread storage and delivery device of the generic type which has an increased utility value.
  • An optimal adaptation to the most varied yarn qualities is realized. Even if highly elastic threads are stored and a high throughput is required, an orderly large thread supply can be stored on the storage body. There is no danger that layers of yarn will overlap during the sudden pulling, because of the particularly favorable thread feed towards the end of the pull.
  • the thread When the thread is applied, it first comes to the conical widening and then to the crosspieces lying to it, the conical widening, with its regions lying between the webs, having a projecting effect on the thread placed on it. The webs, in turn, promote slipping towards the end of the trigger.
  • the thread need not be brought from a polygonal to a cylindrical body.
  • the advancement of the thread layers is optimized by the webs, which themselves form an angular groove. This means that the corresponding area has a greater inclination than the rest. The area with the greater inclination accommodates the shifting of the thread layers. If, in particular, highly elastic threads are processed with high throughput, this corresponding area comes into effect. If, on the other hand, the elasticity of the threads to be processed decreases, the angular fillet area of the webs can be partially or completely inserted into the slots, with other winding and feed ratios being achieved.
  • the slot-side end of the webs can be adjusted in the radial direction.
  • the angle fillet areas of the webs can therefore be set to a greater or lesser pitch depending on the yarn quality to be processed.
  • the incline of the webs changes as well. This means that the incline of the web fillet areas also increases as the incline of the webs increases increases associated with a better slipping of the threads, which is particularly advantageous in the case of highly elastic threads.
  • the trigger-side end of the web is pivotally mounted on the winding body and the section of the web facing this end runs approximately parallel to the jacket wall of the winding body which is designed as a drum.
  • the slipping conditions change accordingly when the web pivots about the end of the winding body on the take-off side.
  • the parallel section partially lies in grooves in the drum wall, which grooves extend from the slots.
  • the conical extension and the jacket wall can be designed in one piece.
  • the thread draw is favored in that the ends of the parallel webs protrude into an approximately spherical ring head surface of the winding body. If necessary, the thread is drawn off over this ring head surface.
  • a simple longitudinal adjustment of the webs can be carried out by means of an adjusting screw in the center of the top face of the winding body, which causes the longitudinal adjustability.
  • Structural advantages result from the fact that the webs are combined and pivotable against spring loading on a bushing arranged longitudinally displaceably in the interior of the winding body and on the fingers of a sleeve which is displaceable centrally on the bushing support. With the displacement of this sleeve, which is done by means of the additional screw, the radial adjustment of the webs can take place. If the sleeve is moved alone, only the webs are axially adjusted.
  • the dimension of the fillet angle of the webs is approximately 176 ° and that of the conical extension surface is approximately 45 °.
  • the thread storage and delivery device has a drive motor 2 flanged to a housing 1. Its motor shaft 3 is connected in a rotationally fixed manner to a thread eyelet carrier 4. The incoming thread F passes into a central channel 5 of the motor shaft 3 and from there into a radial channel 6 of the thread eyelet carrier 4.
  • the thread eyelet carrier 4 is assigned a braking device designated as a whole as 7.
  • the motor shaft 3 continues beyond the thread eyelet carrier 4 in the axial direction and is mounted on the projecting section in a housing bushing 8.
  • the winding body 9 has a jacket wall 10 designed as a drum, which merges into an end wall 11 at the end of the thread storage and delivery device on the take-off side. The latter is supported on the end face of the housing bushing 8.
  • the trigger-side end of the casing wall 10 is overlapped by a spherical ring head surface 12. The same goes over a step 13 into a radially directed end wall 14. Both the end wall 11 of the jacket wall 10 and the end wall 14 of the ring head surface 12 are held on the housing bush 8 by means of screws 15 and are therefore non-rotatable.
  • the free end of the jacket wall 10 merges into a conical widening 17 via an angle groove 16.
  • the pitch angle ⁇ of this conical extension is 45 ° in the exemplary embodiment, cf. in particular FIG. 6.
  • the conical extension 17 is followed by a parallel section 18 which is covered by the thread eyelet carrier 4.
  • a bushing 19 is axially displaceably mounted on the housing bushing 8 and merges into a radially directed flange 20 at the end of the winding former 9 on the take-off side.
  • cavities arranged in the same angular distribution between the flange 20 and the flange plate 22 are created for receiving radially angled ends 23 of approximately parallel webs 24 of the winding former 9.
  • the parallel extending section 25 of the webs 24 partially lies in grooves 26 of the drum wall 10 and projects beyond them. As can be seen from Fig. 3, grab. the parallel webs 24 with their ends in recesses 27 of the ring head surface of the winding body 9.
  • the angled ends 23 of the webs 24 are acted upon by compression springs 31. They are seated in bores of a sleeve 32 which is non-rotatably arranged on the sleeve 19. Axial displacement of the sleeve 32 in one direction is prevented by a stop ring 33. In the basic position, the ends 23 are supported on the flange 20. The ends 23 are equipped with a throat 34. A projection 35 of the flange plate 22 engages in this in a form-fitting manner.
  • a sleeve 36 which is displaceably arranged on the bush 19 and from which radially directed fingers 37 extend, corresponding to the number of webs 24, on which the end regions 29 of the webs 24 are supported.
  • the flange 20 of the sleeve 19 is the carrier of a screw 38 which is accessible from the top surface of the winding body 9. This screw is held in the flange 20 so that it cannot move in the axial direction. Its thread 38 'engages in an internal thread 39 of the sleeve 36, which in turn is arranged displaceably on the sleeve 19. If the screw 38 is now turned so that, for example, the sleeve 36 reaches the dot-dash position according to FIG. 5, this leads to a pivoting of the webs 24 against their spring loading, the projection 35 of the flange plate 22 being the fulcrum forms.
  • the sleeve 19 with its webs 24 can also be moved as a whole unit on the housing sleeve 8.
  • the flange 20 is connected via webs to a collar 40 which forms a corresponding internal thread.
  • An adjusting screw 41 which causes the longitudinal adjustability, engages in the same in the center of the head surface of the winding body 9.
  • a locking ring 42 ensures that the adjusting screw 41 is fixed in the axial direction on the end wall 14. So if the adjusting screw 41 is rotated, this leads to a displacement of the sleeve 19 with the webs 24 attached to it in the axial direction.
  • the winding body 9 can be assigned a mechanically or in the form of a light barrier control device, the task of which is to sense the winding supply on the winding body 9 and to control the drive so that there is approximately always a predetermined winding supply on the winding body.
  • the ring head surface 12 is assigned a damping ring 43, which is illustrated schematically in FIG. 3, the bristles 43 'of which press on the ring head surface.
  • the thread F leaving the thread eyelet 4 'initially reaches the conical extension 17 and from there into the throat K between the region 29 of the webs 24 and the conical extension 17.
  • the region of the region 29 lying between the region 29 of the webs Conical extension 17 accordingly forms a feed section for the thread F placed on it.
  • thread layers are placed on the regions 29 of the webs 24 tapering in the direction of the withdrawal end. 3 and 6 is such a basic position of the webs. before that after the throats 28 there is still a slight tapering of the webs 24 towards the trigger end.
  • the thread layers are accordingly applied to a polygonal winding body formed by the webs 24.
  • the withdrawal end of the thread F slides over the ring head surface 12 and passes the damping ring 43, from where the thread F passes through a central sleeve 44.
  • the bushing 19 can be displaced in the axial direction by means of the adjusting screw 41, the regions 29 of the webs 24 moving into the slots 30 of the conical widening, see FIG. 9 Accordingly, the thread layers, after being applied to the conical widening, reach directly on the sections 25 of the webs 24 without the regions 29 having an effect.
  • the screw 38 is to be turned, accompanied by a displacement of the sleeve 36, the webs 24 being pivoted outward in the radial direction via the fingers 37, see FIG. 10.
  • the throat K thus changes its position Furthermore, the tapering of the webs in the take-off direction is greater, which favors the thread advance, in particular in the case of these highly elastic threads, but avoiding the thread layers overlapping due to the elasticity of the threads.
