Definitions

  • the present invention relates to a device for positioning textile cops full of wound thread according to the end of their tapered bobbins onto which the thread is wound.
  • the thread produced in ring spinners, or similar machines is collected and wound onto rod-shaped tapered bobbins which have different diameters at each end.
  • the accumulation of thread wound onto the bobbins gives rise to the formation of spinning cops, which must be correctly placed and positioned on the automatic loading devices in order to supply the spooling stations.
  • Positioning means that the cops must all be placed in the same direction and consequently the direction of taper of their bobbins must all face in the same direction.
  • some of the known state-of-the-art devices have positioning and straightening elements which are fixed and not movable.
  • the detectors of the position of the cop are slots made in plates, or openings between two fixed elements.
  • the said slots or openings are located at the end of a slide, or in a feed channel, or in a feed well or chamber in order to locate the cop to be positioned on them.
  • the said slots or openings are calibrated with a smaller width than that of the largest diameter of the cop bobbin and with a larger width than that of the smallest diameter of the cop bobbin. Since the cop bobbins have a slight difference between the diameters of their ends, in such a constructional solution, a slight variation in the width of the two slots, or two openings is evident. Clearly, the slightest deformation of the ends of the cop bobbin, or the laceration of one of the end edges of the said bobbin, creates operational jams in the positioning device during the automatic supply stage of the spooling stations.
  • the main aim of the present invention is therefore to ensure correct operation of the entire stage of supplying cops to the spooling stations, so that the faults and disadvantages connected with current state-of-the-art devices, together with those listed above, are avoided.
  • An additional aim of the present invention is to provide a device which has a simple constructional structure and is made so that the method of positioning the cops can be carried out quickly and without inconvenience.
  • the device covered by the invention in no way alters the operating system and equipment connected with the spooling stations, and so no reference shall be made to the conventional spooling station or to the elements and equipment which enable automatic supply of the cops.
  • the present invention relates to a device for positioning textile cops according to the end of their tapered bobbins in which the said device comprises in operational co-ordination:
  • the present invention also relates to a device which in practical operation ensures that the distance between the front cams, of both pairs located at either end of the cop, must be such as to be both considerably less than the larger diameter of the tapered bobbin of the cop and also considerably greater than the smaller diameter of the tapered bobbin of the said cop.
  • the device for positioning textile cops for the practical embodiment according to the present invention, also provides that one cam of each front pair has a protruding pin on its outer side and the said pin interferes with the flat top extension element of the flyer that is supporting the corresponding end of the cop, which has the larger diameter of its bobbin.
  • the device for positioning textile cops for the practical embodiment according to the present invention, also provides that each supporting flyer pivots on a pin round which it rotates overcoming the elastic action of a spiral spring also located around the said pin.
  • cop 3 will have the support of flyer 9 withdrawn from its end 24, so that cop 3 rotates falling by gravity around the single support constituted by the other flyer 8.
  • the said cop 3 falling downwards will move on vertically into the feed well or channel (not drawn), due solely to its own weight, so that the larger-diameter end 24 will be at the bottom and the smaller-diameter end 22 at the top (see Fig. 17).
  • the reverse crosswise thrust of toothed shaft 1 is activated, which re-establishes the initial configuration of the device, waiting to receive and house the next cop to be positioned.
  • cop 3 is made upright with its larger-diameter end 24 downwards even if the latter is resting on flyers 8 and 9 with the ends inverted as compared to the position shown in Figures 1 and 13 and described above.
