Definitions

  • the invention provides a waste cone for a spindle such as used in a drawtwister which is capable of storing a large quantity of waste material during a spinning process.
  • the waste cone is mounted on the spindle and cooperates with a means which serves to radially increase the upper limit of the waste cone significantly over the radial extent of the cone.
  • This means is selectively positioned either in a first position with a tube disposed in place on the spindle to permit build up of a waste bunch of the waste material or in a second position with the tube and resultant package thereon removed from the spindle to permit removal of the waste bunch.
  • the means for radially increasing the upper limit of the waste cone is constituted by a flange which is removably mounted on the upper end of the waste cone. This flange serves as an abutment to contain the waste material on the cone below the flange.
  • the means for increasing the upper limit of the waste cone is formed by a plurality of fingers which are pivotally mounted at one end on the waste cone for radial displacement. These fingers are recessed in the side wall of the waste cone and are formed with extensions at the free end which define a plurality of circumferentially spaced abutments to contain the waste material therebelow when the fingers are pivoted outwardly of the waste cone.
  • the fingers of each waste cone are further provided with cam surfaces which are exposed to engage the tube mounted on the spindle so as to move outwardly as the tube is slid downwardly into place on the spindle.
  • FIG. 1 illustrates a partial side view and cross-sectional view of a waste cone according to the invention in place on a spindle;
  • FIG. 2 illustrates a similar view to FIG. 1 of a modified waste cone according to the invention.
  • a spindle blade 1 receives a waste cone 2 which is pressed onto the blade 1 directly against and above a whorl 3.
  • the waste cone 2 is, as is known, provided with milled slots 4 distributed uniformly over the circumference of the cone 2 and which are arranged vertically and milled to increasing depth towards the upper end.
  • a limiting flange 5 is set into the top part of the cone 2.
  • This flange 5 has an outer radius R, which is considerably larger than the radius R of an upper flange 6 of the whorl 3.
  • the flange 5 is also provided with a central recess 7 having a cylindrical side wall which is inserted into an opening 8 of the cone 2 having a conical or tapered mouth.
  • a plurality of locking elements in the form of elastic cams 9 protrude at the outer circumference of the recess 7 and fit in a means such as a matching annular groove 10 of the cone 2.
  • a somewhat enlarged periphery of the flange 5, uniformly distributed radial recesses l 1 and 12 are provided in order to carry on the thread to be wound onto the cone 2.
  • the recess 7 is provided with a central hole 13 to permit passage over the spindle blade 1.
  • the outer rim of the flange 5 has a depending lip which serves to further define a contained space for receiving waste material 15.
  • the flange 5 is inserted with the central hole 13 over the tip of the spindle blade 1 and is dropped.
  • the flange 5 then centers in the conical upper part of the opening 8 of the waste cone 2.
  • the thread (not shown) is then fastened to the spindle blade 1 by means of a few wraps, whereupon a tube 14 is donned onto the spindle blade 1 so that the thread is clamped between an annular insert 14, as is known, of the tube 14 and the spindle.blade l.
  • the flange 5 is pressed into the opening 8 and the cams 9 lock in the groove 10. With the flange 5 in this position the spindle brake is opened and the spindle 1 rotates slowly.
  • the waste bunch 15 builds up until the thread is wound onto the tube 14 and the package build of package 16' is started at the normal operating speed.
  • the spindle is stopped and the package 16 including the tube 14 are doffed.
  • the limiting flange including the waste bunch 15 are gripped with both hands and are lifted to a position away from the spindle blade 1 whereupon the waste bunch 15 is thrown away.
  • FIG. 2 An alternative to the waste cone design described above is shown in FIG. 2.
  • the waste cone is provided with a plurality of fingers 16 each of which is supported and outwardly pivotably mounted at one end in respective slots 17 in the upstanding side wall of the waste cone.
  • the fingers 16 which are recessed in the slots 17 are each provided at the lower ends with a limiting surface 18 which functions to contact the wall of a slot 17 so as to limit the outward pivoting of each finger 16.
  • the upper part of each finger 16 is formed with-an extension 19 which projects towards the outside of the waste cone and is made from a soft flexible material, such as rubber, etc., in order to avoid accidents, particularly at high operating speeds.
  • a soft flexible material such as rubber, etc.
  • each finger 16 also has an upper surface 20 which is inclined downwardly towards the inside in order to engage the tube 21 which may also be provided with the conventional annular insert 21' so that upon insertion of the tube 21 from above, the tube 21 moves against the surfaces 20 to cause the fingers 16 to move outwardly into their operating position.
  • the waste cone When the fingers 16 are in the outermost operating position, the waste cone is ready to take up the waste bunch 22. After doffing of the tube 21 containing the full package, the fingers 16 drop back into the idle position thus freeing the waste cone so that the waste bunch 22 can be doffed axially upwardly without obstruction and can be eliminated.
  • This latter waste cone (FIG. 2) uses no loose parts which must be lifted from the waste cone so that both hands of the operator are free for other manipulations.
  • said movable means includes a second flange mounted on one end of said waste cone in said first position and removed from said waste cone in said second position.
  • said second flange includes a central recess and a plurality of locking elements on said recess, and wherein said waste cone includes an opening receiving said recess therein and having means to receive said locking elements.
  • a plurality of fingers pivotally mounted at one end thereof on said waste cone for radial displacement of an opposite end thereof from said waste cone to radially increase the upper limit of the winding space of said waste cone.
  • said waste cone includes a plurality of slots, each of said fingers being recessed in one of said slots.
  • each finger includes a surface thereon for limiting the outward radial displacement thereof.
  • each finger includes an extension at the free end extending radially outwardly of said waste cone.
  • each extension is made of soft elastic material.
  • each finger has a surface at the free end inclined downwardly towards the inside of said waste cone.
  • waste cone mounted on said spindle below said tube and adjacent said flange for winding of waste thread thereon
  • radially retractable means extending radially from said waste cone at an end opposite said flange for radially increasing and decreasing the upper limit of the winding space of said waste cone, said means being of larger radius than said flange in an outermost operating position thereof.
  • said means includes a plurality of fingers mounted on said waste cone for radial displacement to enlarge the radius of said waste cone at the upper end thereof.
  • a flange removably mounted on one end of said waste cone for radially increasing the upper limit of said waste cone, said flange including a central recess and a plurality of locking elements on said recess, and wherein said waste cone includes an opening receiving said recess therein and having means to receive said locking elements.
  • a plurality of fingers mounted on said waste cone for radial displacement to enlarge the radius of said waste cone at the upper end thereof.
  • each said finger includes a surface inclined downwardly towards the inside of said waste cone engaging said tube whereby said fingers are moved outwardly of said waste cone upon movement of said tube downwardly on said spindle and against said surface.
