Definitions

  • the invention relates to a spinning device with a drafting system, with a spindle receiving a bobbin and with a bell which engages over the spindle and which is mounted coaxially to the spindle by means of a bearing pin, through which in the axial direction an opening leading to a thread outlet opening on the outside of the bell leading thread channel is running.
  • a thread balloon is formed between a rotor and a thread guide arranged coaxially to the spindle.
  • This thread balloon is one of the essential factors by which the spinning speed is limited.
  • an air resistance acts on the thread balloon and on the other hand a centrifugal force.
  • a spinning device of the type mentioned DE-A 34 00 327
  • the formation of a thread balloon is completely suppressed, so that the limits given thereby are eliminated and higher spinning speeds are possible.
  • differences arise in the winding speed and thus also in the thread tension. These thread tension differences are compensated for in the area of the thread, which runs in the form of spirals on the outside on the outside of the bell. The pitch of these coils changes depending on the thread tension. Overall, the thread tensions that occur are significantly lower compared to the thread tensions in ring spinning devices.
  • a spinning device is also known (EP-A 0225 660), in which a bell over the spindle is provided, which has a cylindrical part, which is followed by a conical part in the thread running direction.
  • the thread rests on the inside due to the centrifugal forces and at the end of the cylindrical part is guided outwards onto the conical area via a thread outlet opening.
  • the thread should form a balloon defined in terms of its length and diameter.
  • the bell is stored outside in the cylindrical area. This camp must have correspondingly large dimensions, so that the achievable spinning speeds are limited.
  • the invention has for its object to provide a device of the type mentioned in such a way that the possibility of automatically compensating for thread tension changes is further improved.
  • This configuration ensures that a thread balloon of a defined shape can be formed before the entry into the bearing journal of the bell, which is deformable to compensate for thread tensions. This makes it possible to take advantage of the spinning advantages of a thread balloon without having to accept the disadvantages.
  • the thread balloon can be dimensioned by the choice of the eccentricity in such a way that the occurring tensions assume defined values.
  • the guide element rotates with the bell.
  • the thread balloon then rotates at the speed of the bell.
  • the guide element is attached to the bearing journal.
  • the spinning device contains a drafting device, of which only one pair of delivery rollers (10) is indicated.
  • the spinning device also includes a spindle (12) which carries a spool (11) on which a thread is wound.
  • the spindle (12) is provided in a manner not shown with a drive, for example a belt drive or a single motor.
  • a bell (13) is arranged coaxially to the spindle (12) and is supported in a stationary holder (22) by means of a bearing journal (14) and roller bearings (23, 24).
  • the bell (13) has a cylindrical section which has a slightly larger inner diameter than the coil sleeve of the coil (11) and which is adjoined by a conically widening section, the conical shape of which is adapted to the cop structure.
  • the bell (13) is provided with an axially directed thread channel (15), to which an obliquely downward and outward section adjoins, which has a thread outlet opening (16) on the outside of the bell (13 ) flows out.
  • Coil (11) and bell (13) are relative in the axial direction in a known manner, not shown here can be shifted towards one another in order to build up the known cop shape when the thread is wound.
  • the thread emerging from the pair of delivery rollers (10) of the drafting system passes through a thread guide (17), a so-called swab tail, and then runs into the thread channel (15) of the bearing journal (14), from which it exits at the thread outlet opening (16) and into Spirals on the outside of the bell (13) runs to the lower edge of the bell (13), from which it then goes directly to the coil (11).
  • a thread balloon is generated before the entry into the thread channel (15) of the bearing pin (14).
  • the thread channel (15) of the bearing pin (14) is preceded by a plate-like extension (19), in which there is an obliquely directed channel section which forms a thread inlet opening (30) located in the top of the extension (19), which is eccentric to the Axis of rotation of the bearing pin (14).
  • the shape of the thread balloon that forms does not change depending on the vertical spindle movement.
  • the shape of the thread balloon depends on the vertical distance of the thread guide (17) from the plate-like attachment (19) and on the eccentricity of the thread inlet opening (30). It is possible to influence the shape of the thread balloon by changing the position of the thread guide (17) and / or the entry opening (30).
  • a plurality of channel sections connect to the thread channel (15), which end in the attachment (19) with different eccentricities with respect to the axis of rotation of the bearing journal (14).
  • the thread channel (15) is attached with an inclination to the axis of rotation of the bearing pin (14), so that the thread inlet opening (18) is eccentric to the axis of rotation of the bearing pin (14) lies. This also forms a thread balloon between the bearing journal (14) and the thread guide (17).
  • the thread channel (15) extends in a straight line from the eccentric thread inlet opening (18) to a thread outlet opening located on the outside of the bell (13).
  • the bearing journal (14) is provided with a plate-like attachment (20), in which a radial channel section is provided, which is provided with a thread entry opening (25) in the region of its outer surface.
  • the rotation circle of the mouth (25) is the basis for a thread balloon which is formed and which is indicated by a dash-dotted line.
  • the axially directed thread channel (15) is closed at the top by a stopper (31).
  • a plate-like attachment (21) is attached to the bearing journal (14) as an exchangeable or detachable component, for example pressed in or screwed in by means of a thread.
  • the plate-like attachment (21) is provided with a channel section which extends in the extension of the axially directed thread channel (15) and has an opening lying in the axis of rotation, which forms a thread inlet opening (29). With the help of this thread inlet opening, spinning can be carried out without a balloon being formed.
  • a radially directed channel section branches off from this channel section and opens in a thread entry opening (25) in the lateral surface of the attachment (21).
  • a plurality of transverse channels are guided to this channel section from the top, each forming further thread inlet openings (26, 27, 28), each lying on a different radius with respect to the axis of rotation and thus being able to produce a thread balloon with a different diameter.
  • the thread entry opening (25, 26, 27, 28, 29) used in the respective spinning process is selected depending on the speed and / or the fiber material used.
  • blind channels which are mirror-symmetrical to the channels which are eccentric to the axis of rotation, in order to reduce unbalance forces in this way.
  • the thread entry openings (18, 25 to 28 and 30) and the thread exit opening can be protected against wear with ceramic inserts.
