Definitions

  • the invention relates to a yarn package whose thread has a protruding from the winding inner portion and an opening on the outer circumferential surface of the yarn package extending end portion. Furthermore, the invention relates to a method for forming a yarn package from a yarn, wherein the yarn is wound from a starting portion, which protrudes from the winding inside the finished yarn package, and the yarn is separated at an outgoing from the outer circumferential surface of the yarn package formed end portion of the yarn becomes. Furthermore, the invention relates to a device for forming a yarn package from a yarn, wherein the yarn of the yarn package has a protruding from the winding inner beginning portion and extending on the outer circumferential surface of the yarn package end portion.
  • Yarn wrap of the type mentioned also known as bobbins or cocoons
  • Such yarn packages are used in particular for the production of embroidery by means of embroidery machines and quilting by means of quilting machines and the like.
  • the bobbins are placed in boats, wherein the protruding from the winding inner initial section of the thread is pulled through different eyelets of the shuttle. Since the yarn packages are used up after a few hours of operation and must be renewed and embroidery machines have a large number of such to be filled shuttles, this work is associated with a considerable effort.
  • a method according to the invention for producing such a yarn package has the features of claim 4.
  • An inventive device for forming such a yarn package has the features of claim 10.
  • the yarn package is not wound on a yarn carrier, in particular sleeve, but rather wound without a carrier.
  • Such yarn packages are also referred to as bobbins or cocoons.
  • the yarn of the yarn package has a protruding from the winding inner beginning section 1, d. H. the initial section exits the yarn package in the region of its central longitudinal axis or its inner circumferential surface in the axial direction of the yarn package.
  • the thread or the yarn of the yarn package of a fusible plastic is in this case welded under heat.
  • the welding extends in an annular region 4 around the outer lateral surface 3, wherein this annular region 4 is preferably located approximately in the longitudinal center of the yarn package.
  • Not only the end section 2 but also other thread sections lying in the area of the outer lateral surface 3 are welded together, but this does not impair the yarn package, since such yarn packages usually can not be finished by the end of the thread anyway.
  • the thread is consumed when embroidering starting from the initial section 1 from radially inward to radially further outward, with the inner circumferential surface increasingly migrating radially outward.
  • the yarn package is renewed when its wall thickness only comparatively low.
  • Fig. 2 shows the yarn package before the cohesive connection of the end portion 2 with other lying on the outer surface of the yarn package thread sections.
  • FIG. 3 and 4 show a schematic representation of an embodiment of a unit 6 for welding the end portion 2 of the thread.
  • the yarn or yarn Before feeding a yarn package 5 to this unit 6, the yarn or yarn is wound in a conventional manner to a yarn package 5 and after the winding process, the yarn is separated following its outgoing from the outer surface of the formed yarn package end portion.
  • the yarn packages 5 produced in this way are fed to a separating device, not shown in the figures, and pass from the latter through a supply pipe 7 into the unit 6.
  • a respective yarn package 5 is hereby placed in the area between the rotatably mounted ones Guide rollers 8, 9 and support pins 10, 11 introduced.
  • a pin-shaped support member 12 in the illustrated embodiment supports the inserted yarn package 5 from below.
  • the rotating device 13 is initially retracted from the position shown in Figs. 3 and 4 and lifted from the yarn package 5 (relative to Figs. 3 and 4 shifted to the left).
  • the broom 14 is initially retracted from the position shown in Fig
  • the rotating device 13 has in the illustrated embodiment, a drive roller 15 which is displaceable in rotation via a drive motor, as indicated in Fig. 3 only schematically.
  • the carrier 17 which supports the drive roller 15 is displaceable in the direction of the double arrow 18, for example by means of a piston-cylinder unit 19 indicated only schematically in FIG. 3.
  • the drive roller 15 is thereby lifted between a thread lifted off the yarn package 5 and one against the outer jacket surface 3 the Garnwickels 5 employed position adjustable.
  • the axis of rotation of the drive roller 15 is parallel to the longitudinal axis of the yarn package fifth
  • the drive roller 15 When the drive roller 15 is displaced into the drive position shown in Figs. 3 and 4, it presses the yarn package 5 to the rotatable guide rollers 8, 9 and the yarn carrier is by the at least three circumferentially adjacent thereto rollers which are circumferentially from each other are spaced apart, preferably in the circumferential direction are uniformly spaced, out.
  • the drive roller 15 from the drive motor 16 of the yarn package 5 By rotation of the drive roller 15 from the drive motor 16 of the yarn package 5 is rotated about its longitudinal axis.
  • guide rollers 8, 9 for example, non-rotatable guide pins can be provided.
  • the broom 14 is moved from its position lifted from the outer lateral surface 3 of the yarn package 5 into its position shown in FIG. 4, for example by means of a piston-cylinder unit 20.
  • the bristles 21 are located of the broom 14 on the outer circumferential surface 3 of the yarn package 5 and the end portion 2 of the thread is thereby applied to the outer circumferential surface 3, in an annular extending around the outer circumferential surface alignment.
  • the mobility of the brush 14 is indicated in Fig. 4 by the double arrow 22.
  • the heating stamp 23 is moved from its position shown in Figs. 3 and 4, lifted from the outer surface 3 of the yarn package position in the direction of the yarn package 5 and applied to the outer circumferential surface, in the annular region 4, in which is also applied by the broom 14 to the outer surface 3 end portion 2 of the thread.
  • the heating punch 23 is adjustable, for example, by a piston-cylinder unit schematically indicated in FIG. 3, the double arrow 25 symbolizing the adjustment direction.
  • a heating element 26 for heating the heating punch 23 to the desired welding temperature is shown schematically in FIGS. 3 and 4.
  • the heating punch 23 is left for a defined period in its voltage applied to the outer lateral surface 3, wherein the yarn package has rotated at least once, preferably several times about its longitudinal axis in this time.
  • the heating punch 23, the broom 14 and the drive roller 15 are in turn lifted from the yarn package and the support member 12 is withdrawn, for example by means of a piston-cylinder unit 27, whereupon the finished yarn package from the area between the guide rollers 8, 9 and the support pins 10, 11 falls down.
  • the support pins 10, 11 serve to prevent overturning of the yarn package 5, when the drive roller 15 is lifted from the yarn package. In employed at the yarn package 5 state of the drive roller 15, a game between the yarn package 5 and the support pins 10, 11 exist. Instead of support pins 10, 11 also other support members can be provided.
  • the band could also have a window recess extending in a middle region of the band relative to the width of the band and in the longitudinal direction of the band, through which hot air flows.
  • a welding of the end portion 2 by irradiation with a laser beam would also be conceivable and possible.
  • Suitable for welding yarns which are also referred to as melted yarns may consist for example of polyester, polyamide, polypropylene or a mixture thereof.
  • a mixture with non-meltable proportions, such as cotton is conceivable and possible.
