Definitions

  • this bunch automatically slips down onto the spindle during the extraction of the full bobbin (cop) at the time of doifing, at the same time, changing its form into a helically varied bunch and becoming wrapped about said spindle, its lower end supports the spinning yarn which has been delivered from the front roller through the traveler, thereby performing the function of tethering said spinning yarn on the spindle.
  • the upper yarn end of the aforesaid varied bunch deformed into a helical shape is a free end of irregular length created when the connecting yarn between said varied bunch and the full bobbin is broken by stretching during the extraction of said bobbin.
  • this upper yarn end is caused by the reaction force at the time of breakage to hang down and, moreover, causes the varied bunch to tend to become loose from its upper part.
  • this upper yarn end causes the varied bunch to slip off the spindle, whereby the tethering of the appropriate spinning yarn at the start of the succeeding spinning operation is frequently made impossible. Accordingly, such drawbacks resulting thereby as the troublesome procedure of yarn piecing exist in conventional machines of this type.
  • FIGURE 1 is a side elevational view, partly in vertical section and with parts cut away, showing the entire construction of a spindle apparatus according to the present invention
  • FIGURE 2 is an elevational view showing the state of the bunch formed on the bunch cylinder of the spindle apparatus shown in FIGURE '1;
  • FIGURE 3 is an elevational view showing the state of the yarn end of the bunch being cut off and prepared at the time of extraction of the full bobbin in the doffing operation;
  • FIGURE 4 is an elevational view showing the state of the bunch on the bunch cylinder, as it unwinds itself therefrom, moving onto the bobbin;
  • FIGURE 5 is a plan view indicating the principles utilized in the automatic unwinding of the bunch.
  • the spindle apparatus shown therein has a spindle 1 supporting a bobbin 2, a bunch cylinder 4 fitted rot-atably on the spindle 1, a wharve 5 of the bunch cylinder 4, a spindle wharve 6 fitted on and fixed to the spindle 1, an endless knife 7 fitted about and fixed to the top of said bunch cylinder 4, and a collar 8 fitted on and fixed to the spindle 1 which is adapted to retain the bunch cylinder and prevent it from rising, and, at the same time, to center the lower end of the bobbin in substantially concentric alignment with the spindle 1 by the fitting of the outer peripheral surface of said collar 8 in the lower inner bore of the bobbin 2.
  • the endless knife '7 may alternatively be formed integrally as a single member with the collar 8, or it may be supported in an intermediate position between the bunch cylinder 4 and the collar 8.
  • the above-mentioned wharve 5 of the bunch cylinder has a slightly larger diameter than that of the wharve 6 of the spindle.
  • These two 'wharves are driven in the same rotational direction by a common tape 10 stretched thereover, with a slight difference in rotational speeds between the two wharves being due to the above-mentioned difference in diameters. That is, by this difference in speeds, the spindle 1 is caused to advance slightly in rotation relative to the bunch cylinder 4.
  • FIGURE 2 shows the spindle apparatus in the state resulting from the following operation.
  • a bobbin 2 is fitted onto the spindle 1 of the spindle apparatus of the above-described description a spinning yarn Y is wound about the said bobbin 2 to form a package, which, upon attaining a predetermined configuration, becomes a full bobbin 3; at the same time, ring rail 12 descends to its lowest position; spinning yarn Y is guided onto the bunch cylinder 4 by a traveller 14 supported on a ring 13, which is fixed on the ring rail 12, and is wrapped thereabout several turns to form a bunch 9; then the tape 10 stops; and, simultaneously, both the spindle .1 and thebunch cylinder also stop.
  • the bunch 9 is connected with the lower part of the spinning yarn Y which is delivered from the front roller (not shown) by way of the traveller to the bunch 9 and, at the same time, is connected with the upper part of a yarn Y which is irregularly wound in a spiral path about the outer surface of the full bobbin 3 toward the lower part thereof.
  • One part of the said yarn Y is stretched across lower end of the bobbin 2 and, being stretched over the sharp end of the endless knife 7, become bent.
  • the bunch 9 is formed in this state, and during its formation, the rotation of the full bobbin 3 advances slightly relative to that of the bunch 9 because of difference in rotational speeds of the spindle 1 and the bunch cylinder 4. Accordingly, the yarn Y subjected to rotation together with the full bobbin is pressed on the sharp end of the endless knife 7, while sliding on said sharp end, whereby the yarn Y is cut. In the case, if the yarn is not completely out off, the yarn Y is pulled positively by the succeeding extracting operation of the full bobbin whereby the press force between the sharp end of the knife '7 and the yarn increases sufficiently to cut the yarn.
  • the upper part of the yarn Y is retained by the full bobbin 3 and becomes the yarn end thereof, and the lower part of the yarn Y becomes the yarn end of the bunch 9. While said yarn end of the bunch Q is a free end, it can always be prepared to have a short, constant length.
  • FIGURES 4 and 5 indicate the principle of, and the state resulting from, the following operation.
  • the full bobbin 3 is extracted from the spindle 1 and replaced by a new empty bobbin 2.
  • the ring rail 12 is raised to a predetermined position and the spindle starts to rotate for the succeeding spinning operation.
  • the bunch 9 is automatically unwound and transferred onto the newly set bobbin 2 as indicated in FIGURES 4 and 5.
  • a bridging yarn Y which extends across the bunch and the bobbin is taken up at its upper part on the bobbin 2 and also is wrapped by a yarn part Y, which has been initially wound about the surface of the bobbin and becomes grasped between the yarn Y and the bobbin at a grasping point P. Accordingly, this grasping point P, moving with the rotation of the bobbin 2, rotates together with the bobbin in the direction of the arrows shown in FIGURES 4 and 5 and, drawing the aforesaid bridging yarn Y rotates with slightly advanced speed relative to the bunch 9, in the direction for unwinding the bunch.
  • the bridging yarn Y progressively slackens and becomes bowed in shape as indicated in FIGURES 4 and 5 because of centrifugal force and air resistance due to its rotation.
  • the lower end of the yarn Y unwinds the bunch 9, and the upper end rotates as it is wound about the bobbin 2, whereby the bunch is gradually shifted onto the bobbin until, finally, the bunch is fully unwound.
  • the invention through the utilization of the collar 8 incorporated as one part of the said spindle apparatus, further provides, means whereby the fitting and extraction of the bobbin 2 onto and from the spindle 1 is greatly facilitated, and, moreover, slipping of the bobbin 2 relative to the rotation of the spindle is entirely eliminated.
  • the above-stated means is provided by a clutch member 17 formed on the upper end surface of the collar 8, a blunt shape of the upper conical part 18 of the spindle such as to prevent sticking of the bobbin 2 thereto at the time of fitting on the bobbin and such as merely to hold the bobbin in centered alignment, and a downwardly facing clutch member 19, for engaging with the aforesaid clutch member 17, provided in the hollow lower end of the bobbin 2. Accordingly, the bobbin 2 is held at its upper end in centered alignment.
  • a spindle apparatus for unwinding a yarn bunch in spinning machines comprising a spindle, a bunch cylinder freely rotatable on said spindle for forming a yarn bunch, an endless knife on said bunch cylinder for cutting the connecting yarn between the yarn bunch and a full bobbin, adjacent friction driving elements connected to said spindle and said cylinder and means including a single common driving tape engaging said friction driving elements for driving said bunch cylinder and spindle in the same direction with a slight mutual difference in rotational speed.
  • a spindle apparatus for unwinding a yarn bunch in spinning machines comprising a spindle, a bunch cylinder disposed in a freely rotatable manner on said spindle for forming a yarn bunch, an endless knife on said bunch cylinder for cutting the connecting yarn between the yarn bunch and a full bobbin, a wharve for said spindle, a
