Definitions

  • the invention relates to a device for clamping a Unterwindefadens on a spindle of a textile machine, in particular a Ring spinning machine, the device below one on the spindle plugged Kopses a fixedly connected to the spindle clamping ring and one on the spindle between one through a collar on the spindle defined open position - and one defined by the clamping ring Has closed position axially displaceable clamping sleeve which by means of actuating device is movable using magnetic means.
  • Textile machines in particular ring spinning machines, which are equipped with automatic Doffvorraumen are subject to spin programs with special program phases.
  • a program phase provides For example, the spinning out. During this spinning are Upper, rear and Unterwinditch executed.
  • the thread In the execution of underwindings, the thread is below the Undercurricular crown in the area of a device for clamping a Unterwindefadens on a spindle (underwinding area) out, which is located below the winding tube.
  • the underwinding thread wraps around the Spindle preferably less than 360 °.
  • EP 0 292 856 B1 has disclosed a similar clamping device. Below a fixedly connected to the spindle clamping ring on the spindle axially movable clamping sleeve is arranged, define the upper end side together with the lower end face of the clamping ring the nip. In the lower region of the clamping sleeve elastically deformable support elements are arranged by centrifugal force to the outside. These support elements, together with a conical ring attached to the spindle, cause the collet to be lowered down at high rotational speeds of the spindle. If the speed drops, these support elements push the clamping sleeve back up into the closed position as a result of its elastic prestressing.
  • EP 0 775 769 A1 has disclosed a device which is intended to clamp the underwinding thread in an angular range of less than 360 °.
  • This device also has a clamping ring which is fixedly connected to the spindle and a clamping sleeve axially displaceable on the spindle. Both elements together form a conical, closable clamping gap, which should be kept closed self-locking.
  • the clamping sleeve is held in the lower position during the spinning process by its own weight and is supported on a corresponding collar on the spindle. During this time, the nip is opened. On the outside of the clamping sleeve annular coils are arranged.
  • the present invention the object of a Device of the type mentioned above to be designed so that the clamping sleeve without mechanical contact with the actuating element in the closing and / or open position is reliably locked.
  • the clamping sleeve is held by at least one magnetic element integrated in it either in the closed position defined by the clamping ring or in the open position defined by the federal government. With the aid of the magnetic force thus provided, therefore, the clamping sleeve is fixed in at least one of the two positions, so that no mechanical contact must be present through an actuating device.
  • a surprising advantage of the magnetic clamping device is that the magnetic force increases during the closing of the device and reaches its maximum value in the closed position, while a possibly existing spring force of the actuator decreases and assumes a minimum value in the closed position.
  • the actuator is only for the respective switching of the Clamping sleeve between the open position and the closed position responsible.
  • a particularly advantageous embodiment describes claim 2, wherein the clamping sleeve is also rotatable about the spindle axis and the respective closing or open position is ensured by different from each other positionable poles of the magnets. After this movement, the magnet pairs of the clamping sleeve and the clamping ring act together and thus keep the clamping sleeve reliable in the closed position or in the open position. Stand opposite poles, they repel each other. By contrast, poles of the same name cling to each other when they are close enough to each other.
  • the axially rotatable clamping sleeve on the top side at least two unlike magnetic poles with alternating sequence south pole / north pole, wherein the clamping ring is provided with at least one homonymous magnet pair.
  • the clamping sleeve can be axially rotatable by at least one actuating element and can be moved from the open position into the closed position and vice versa.
  • the clamping sleeve there is a single magnet. This is the clamping sleeve either to the clamping ring or to the opening position defining Pulled the bunch.
  • the clamping ring and in the collar is also one magnet each. These two magnets are arranged offset by 180 ° and polrete the magnet in the clamping sleeve, so that these by rotation each between the areas of action of the two magnets and can be switched and while the clamping sleeve changes position.
  • the by at least one actuating element axially rotatable clamping sleeve also on the underside at least two unlike magnet pairs with alternating Episode South Pole / North Pole, with a lower, connected to the spindle, the open position defining covenant with at least one is provided with the same pair of magnets. This gives you the opportunity that the clamping sleeve in the open position on the interaction the magnet pairs are held or repelled.
  • a further embodiment provides that the at least one pair of magnets in the clamping sleeve cooperates with a single magnet in the clamping ring and / or in the collar defining the open position.
  • the magnets or magnet pairs may be bar magnets.
  • An advantage of the arrangement according to claim 7 is that the electromagnet from a mobile device, for example a hiking cleaner, at already running spindles at any time can be switched and that at the same time also if necessary accumulating thread remnants can be disposed of.
  • a spinning spindle 1 has a spindle lower part 2, which in FIG a spindle bank 3 is attached.
  • a spindle lower part 2 In the spindle lower part 2 is a rotatable Spindle upper part 4 stored.
  • a Sleeve 5 attached, on which a tapered thread 6 to a winding 7 is wound up.
  • the sleeve 5 and the winding 7 form a Kops 8.
  • the tapered thread 6 is guided by a ring traveler 9, which on rotates a spinning ring 10, which in turn on a movable up and down Ring rail 11 is arranged.
  • a device 12th arranged for clamping a Unterwindefadens to the spindle.
  • These Device 12 has in a first embodiment below the plugged Kopses 8 a fixedly connected to the spindle 1 clamping ring 15th and one on the spindle 1 between an open position I and a Closed position II (see FIGS. 2 and 3) axially displaceable clamping sleeve 20th on.
  • Above the clamping ring 15 is a separating knife 18th
  • the clamping sleeve 20 is inventively magnetic force by at least a magnetic element 30 in the defined by the clamping ring 15 Closed position 11 held, d. H. the magnetic element 30 and the steel existing clamping ring 15 cooperate.
  • This open position I is defined by a lower collar 40, which in turn firmly with the Spindle 1 is connected.
  • the clamping sleeve 20 can be used as a tubular element with inner and outer ring and individual chambers be designed in the chambers the Magn etelem ent 30 is arranged.
  • the clamping sleeve 20 ' is axially displaceable and additionally axially rotatable. It has the magnetic element 30 ' on, which in this embodiment each with an eponymous Magnet pair 32 of the clamping ring 15 and a like pair of magnets 32 'in the area of the covenant 40' cooperate.
  • an actuator which the clamping sleeve 20 'axially moves
  • an actuator which the clamping sleeve 20 'turns.
  • the magnetic effect of the magnetic element 30 'be such that in the presence of unlike magnet pairs the Clamping sleeve 20 'raised from the open position I in the closed position II or is lowered.
  • the magnet pairs used in the aforementioned embodiments can be shaped magnets.
  • the clamping sleeve 20 ' has here by webs 26 separate chambers, in which this Form magnets are arranged.
  • magnets according to the invention makes it possible to to ensure within the framework of various design variants that the clamping sleeve 20 or 20 'or 20' '' properly in the closed position II and / or held in the open position I without these end positions a mechanical contact with an actuator is present.
  • the actuator is merely for moving the clamping sleeve between the open position I and the closed position II.
  • the magnetic force is measured so that the actuator can be omitted and the clamping sleeve with the help of Magnet pairs both moved and fixed.
