Definitions

  • the invention relates to a device for clamping a bobbin thread on a spindle of a textile machine, in particular a ring spinning machine, the spindle below an attached cop, a clamping ring fixedly connected to the spindle and a clamping sleeve axially displaceable on the spindle between an open and a closed position having.
  • Textile machines especially ring spinning machines, which are equipped with automatic doffing devices, are subject to spinning programs with special program phases.
  • a program phase represents, for example, spinning.
  • top, bottom and bottom windings are carried out.
  • the thread When underwinding is carried out, the thread is guided below the underwinding crown into the area of a device for clamping an underwinding thread on a spindle (underwinding area), which is located below the winding tube.
  • the underwind thread preferably wraps around the spindle at less than 360 °.
  • the finished spinning bobbin is then pulled off the spindle shaft during doffing by means of automatic bobbin changing devices, the thread between the bobbin and whorl being torn off or cut. However, the thread between whorl and ring traveler remains intact.
  • the clamping active connection is opened and the thread end located therein is moved outwards by centrifugal forces.
  • a device for clamping an underwind thread on a spindle is already known as prior art (DE 199 04 793).
  • the clamping sleeve is pressed into the closed position by spring force and moved into the open position by a fixedly arranged actuating device.
  • the clamping active connection can be removed via a mobile actuation device.
  • the object of the present invention is to design a device of the type mentioned at the outset in such a way that the clamping sleeve can be locked in the closed and / or open position without mechanical contact with the actuating element.
  • This object is achieved in that the clamping sleeve is held by at least one magnetic element either in the closed position defined by the clamping ring or in the open position defined by the collar. With the help of the magnetic force, the clamping sleeve is thus fixed in at least one of the two positions, so that there is no mechanical contact by an actuating device.
  • a surprising advantage of the magnetic clamping device is then that the magnetic force increases during the firing of the device and reaches its maximum value in the closed position, while the spring force decreases and assumes the minimum value in the closed position.
  • the clamping sleeve In order to move the clamping sleeve between the open position and the shooting position, it can be connected to an actuating device which can only be used to carry out the movement sequence, whereas in the closed position and / or in the open position, the clamping sleeve is held properly and functionally by the magnetic element in question ,
  • the axially rotatable clamping sleeve can have at least two magnetic poles of the same name with an alternating sequence of the south pole / north pole, the clamping ring being provided with at least one magnet pair of the same name Be able to move the shooting position After this sequence of movements, the magnet pairs of the clamping sleeve and the clamping ring work together and thus hold the clamping sleeve functionally reliable in the closed position or repel it when the magnet pairs of the same name are used on the clamping sleeve and the clamping ring
  • clamping sleeve is drawn either to the clamping ring or to the collar defining the opening.
  • magnets in the clamping ring and in the collar are arranged offset by 180 ° and have the same polarity as the magnet in the clamping sleeve, so that this can be switched back and forth between the effective areas of the two magnets by rotation, thereby changing the position.
  • the clamping sleeve which can be rotated axially by at least one actuating element, can also have on the underside at least two magnet pairs of the same name with alternating south pole / north pole sequence, a lower collar connected to the spindle and defining the open position being provided with at least one magnet pair of the same name. This makes it possible for the clamping sleeve to be held or repelled even in the open position through the interaction of the magnet pairs.
  • a further embodiment provides that the at least one pair of magnets in the clamping sleeve interacts with a single magnet in the clamping ring and / or in the collar that defines the open position.
  • the magnet pairs can be bar magnets.
  • Figure 1 is a schematic side view of a spinning station with spindle bench, spindle bearing, underwind crown and thread and with device for clamping an underwind thread.
  • Figure 2 is an enlarged view of the device according to the invention in the closed position.
  • FIG. 3 shows a representation analogous to that of FIG. 2 in the open position
  • Fig. 4 shows another possibility of performing the invention in part
  • FIG. 5 shows a plan view of a design option for the dissimilar magnet pairs of the clamping sleeve
  • Fig. 6 shows another embodiment of the invention in part
  • a spinning spindle 1 has a lower spindle part 2, which is fastened in a spindle bank 3.
  • a rotatable upper spindle part 4 is mounted in the lower spindle part 2.
  • a sleeve 5 is slipped, on which a tapering thread 6 is wound into a winding 7.
  • the sleeve 5 and the winding 7 form a cop 8.
  • the incoming thread 6 is guided by a ring traveler 9, which rotates on a spinning ring 10, which in turn is arranged on a ring bank 11 that can be moved up and down.
  • a device 12 for clamping a bobbin thread on the spindle is arranged below the cop 8 on the upper spindle part 4.
  • this device 12 has, below the attached cop 8, a clamping ring 15 which is fixedly connected to the spindle 1 and a clamping sleeve 20 which is axially displaceable on the spindle 1 between an open position i and a closed position II (see FIGS. 2 and 3).
  • a separating knife 18 is located above the clamping ring 15.
  • the clamping sleeve 20 is held in the closed position 11 defined by the clamping ring 15 via magnetic force by at least one magnetic element 30, i. H. the magnetic element 30 and the steel clamping ring 15 cooperate.
  • clamping sleeve 20 is held in the open position I by the magnetic element 30.
  • This open position I is defined by a lower collar 40, which in turn is firmly connected to the spindle 1.
  • the clamping sleeve 20 can be designed as a tubular element with an inner and outer ring and individual chambers, the magnetic element 30 being arranged in the chambers.
  • the clamping sleeve 20 according to FIGS. 2 and 3 can be displaceable with an actuating device 22. If the clamping sleeve 20 according to FIG. 2 is in the closed position II with the aid of the magnetic element 30 or according to FIG. 3 in the open position I, the actuating device 22 is no longer active, so that a contact-free position is given in each case.
  • the clamping sleeve 20 ' is axially displaceable and additionally axially rotatable. It has the magnetic element 30 ', which in this embodiment each cooperate with a magnet pair 32 of the same name of the clamping ring 15 or a magnet pair 32' of the same name in the region of the collar 40 '.
  • an actuating device which rotates the clamping sleeve 20'.
  • the magnetic effect of the magnetic element 30 ' must be such that the clamping sleeve 20' is raised or lowered from the open position I to the closed position II when there are magnet pairs of the same name.
  • the magnet pairs used in the aforementioned embodiments can be shaped magnets, for example, according to FIG. 5.
  • the clamping sleeve 20 has chambers separated by webs 26, in which these form magnets are arranged.
  • a clamping sleeve 20 '"without magnets is provided.
  • This clamping sleeve 20'" is equipped with a metal element 25, for example in the form of a ring.
  • the metal element 25 protrudes into the effective range of two magnets 30 "and 31" of an actuating device 22.
  • the Clamping sleeve 20 '" moved axially without contact, between the open position I and the closed position II.
  • the actuating device only serves to move the clamping sleeve between the open position I and the closing position II.
  • the magnetic force is dimensioned such that the actuating device can be omitted and the clamping sleeve with the aid of the magnet pairs is both moved and fixed.
