Definitions

  • This invention relates to crossing motion pirn winding machines.
  • winding I frames In the yarn winding machines termed winding I frames, it is known, for guiding the yarn, to use instead of a yarn guide having a traversing movement, a roller or drum provided at its periphery with crossed helical grooves or ribs, said roller or drum having only a rotary movement about its axis while the yarn is given a crossing motion by it)- said helical grooves or ribs.
  • the winding frames provided with such rollers or drums owing to the elimination of any jerks, permit of obtaining yarn speeds which are by farhigher than the speeds which may be'obtained with traversing yarn- 15 guides.
  • the present invention consists of a crossing motion pirn winding machine in which the guiding of the yarn is effected by such a roller or drum the periphery of which is formed with crossed helical grooves or ribs, means being provided for imparting to the said roller or drum a longitudinal movement of translation relatively to the pirn.
  • the relative longitudinal movement of the roller may be regular or irregular, it may also be combined with an additional relative traversing movement of small amplitude which provides for a better securing of the yarn to the pirn.
  • the movement of translation can be imparted either to the yarn-guiding roller, the shaft of the pirn being stationary longitudinally, or to the said pirn, the roller being stationary longitudinally or to both of these.
  • the yarn-guiding roller is preferably given a tapered form, so as to provide for a better guiding of the yarn at the small end of the pirn.
  • Fig. 1 is an elevational view, with a section on the line l-l of Fig. 2, of a machinein conformity to the invention,- comprising two winding posts.
  • Fig. 2 is a corresponding plan view.
  • Fig. 3 is a partial front view of the screw and nut device of the feeding mechanism of the yarnguidlng roller.
  • Fig. 4 is a vertical section on the line 4-4 of Fig. 3.
  • Fig. 5 is a partial view of the machine according to-Flg. 1, showing a tapered guiderroller.
  • Figs. 6 and 7 show sections on line. 0-0 and
  • Fig. 8 illustrates the application of the tapered guide roller in the case in which it is stationary longitudinally.
  • the machine comprises two winding posts, that is, it can receive two tubes l and I, each of which is mounted betweenthe centre 2 of a shaft 2 or 3' and an elastic back centre 4.
  • P 1
  • the shafts 3 and 3' which are parallel,”are rotatable in the opposite side-walls of a casing 5. Beyond said casing, the shafts I and 3 are each provided with a driving pulley 6.
  • the yarn F (Fig. l) is guided, for each of the 15 bobbins I, l' by a yarn guide which consists, as known per se, of a roller I, 1 having helical yarn-guiding edges illustrated in the form of ribs 8, 8.
  • the axial length l of the ribs 8, l is much less than 20 the length L of the cylindrical or double-tapered package 9, 9' to be obtained upon the pirns I, I.
  • Each guide-roller I, 1" is slidably keyed to a shaft III or Iii by which it is rotated.
  • the said shaft is rotatable in the casing 5 and is driven 25 from the conjugated shaft 3 or 3" carrying the pirn bya pair of' gear-wheeels ll, I2.
  • Each roller 1,1 can be given a movement of translation along its driving shaft by means or a fork l3 secured to a rod H which is slidable in 30 the casing 5.
  • the two rods H are connected together-by a cross-piece l5, so that it is simply necessary to give to the said cross-piece a movement of translation in the direction of the arrow f, or in the opposite direction, in order to dis- 3 place the guide rollers I, 'I.
  • the said screw passes through an oblong apero ture is (Figs; 3,4) in'a plate 20 which is vertically slidable in a guide 2
  • the upper part I! of the aperture" in the said plate is tapped, so that when the said plate is lowered by a-spring 23, the screw" wlli'mesh 45 with said plate.
  • a rod 24 secured to' the plate 20 serves to raise this latter against the'spring 23, thus uncoupling the. screw ll.
  • the plate. 20 is moreover given, by 5 means of the member 22, a rapid reciprocating movement of small extent, on the longitudinal axis of the screw l8, this movement being superposed upon the above-mentioned longitudinal movement of the said screw, and hence of the cross-piece I5 and finally of the guide rollers 1, 1.
  • This auxiliary movement is imparted to the member 22 which forms a strap (Fig. 4) for instance by means of an eccentric 25.
  • Said eccentric is keyed to a transverse shaft 25, to which is keyed a worm-wheel 21 meshing with a worm 28 keyed to the shaft l8 rotating the guide roller 7.
  • said auxiliary reciprocating movement may be eliminated by disengaging the eccentric 25 from member 22 or by providing for a free rotation of shaft 26 within the eccentric 25.
  • a disc 23 carrying a tappet 30 which, at every revolution of the shaft in the direction of the arrow f" (Fig. 1) will raise, in the direction of the arrow 1 a lever 3
  • is urged in the contrary direction to the arrow 1 by its own weight, assisted or not by a spring.
  • is connected to the shaft 32 through a one way clutch comprising a pawl 34 pivoted at 33 to the lever 3
  • the pawl 34 will slide upon the teeth of the wheel 35 without rotating the latter.
  • the amplitude of the oscillations of the said lever and hence of the impulses imparted to the wheel 35 and the shaft 32 can be adjusted so as to permit of varying the speed ratio between shaft 26 and 32.
  • an adjustable stop 36 on which the'lever 3
  • the stop 36 is mounted on a gear-wheel 31 (Fig. 2) which is loose on the shaft 26 and the angular position of which may be adjusted by an operating knob 38 which is movable in front of a fixed scale 39.
  • the knob 38 is keyed to a sleeve 40 rotatable on the shaft 32, and to the said sleeve is keyed a pinion 4
  • the shaft III of the guide roller 1 drives through the gearing 28, 21 the shaft 26, which, by means of the tappet 30, the lever 3
  • This shaft 32-through the gear connection 42, 43 rotates the screw
  • the eccentric 25 gives it rapid reciprocating impulses of small extent, which further the winding of the yarn upon the pirns I, I
  • each guide roller when the yarn commences its winding, each guide roller has the position shown at 1'; the position shown in full lines in the figures corresponds to the positon at the end of the operation.
  • the feeding speed of the guide-rollers is regulated according to the desired diameter of the pirns by means of the knob 38, which permits of varying the extent of the oscillations of the lever 3
  • the stopping of the machine at the end of each operative movement may be effected by hand, or automaticaly by any suitable electric or electromechanical uncoupling means which are in current use.
  • the said machine which is of a simple construction and of a most approved operation, is capable of filling pirns having a length L which is greater than the length l of the guide roller or rollers, at a very high speed, such as cannot be obtained with the usual yarn guides.
  • the roller 52 has a tapered shape, and comprises helical ribs or grooves 8 having right and left hand pitches, these being crossed at 55.
  • the ribs or grooves 8, the axial length of which is l, impart to the yarn a traversing movement before it is wound on the tube in order to form the pirn 3.
  • the pirn is obtained by the superposition, with a longitudinal spacing, of layers each of which consists of a certain number of turns of yarn.
  • the pirn commences with a tapered part (Fig. 5) formed by the gradual spacing of the first layers; the mean part consists of parallel tapered layers 53, and whatever be its length, it is terminated by a second tapered part having an angle a: at the apex.
  • the guide roller is given an angle at the apex which is practically equal to :r.
  • the said roller is positioned so that its taper will be contrary to the taper of the layers 53 of the pirn.
  • the yarn is not properly guided till to the end of its course and it will form a small edge at the tip of the pirn.
  • the yarn is subsequently unwound, for weaving purposes, it may happen that two or three spiral turns of this edge may be detached at the same time and may make the fabric defective.
  • the said drawback is obviated by the tapered shape of the roller according to the present invention.
  • the tapered roller has further the advantage of providing a compensation for the tension of the yarn. In fact, when the yarn is wound ac-.
  • the tapered roller may be used without any longitudinal movement, it the length of the bobbin should be equal to I (Fig. 5
