Definitions

  • the invention relates to a spinning device with a drafting system, with a spindle receiving a spool and with a bell arranged coaxially to the spindle and overlapping it, which bell has an axial thread inlet and in its jacket a thread outlet opening leading to the outside.
  • 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 due to which the spinning speed is limited.
  • an air resistance acts on this thread balloon and on the other hand a centrifugal force.
  • the invention has for its object to provide a spinning device of the type mentioned so that the possibility of an automatic compensation of the thread tension is further improved.
  • This object is achieved in that a space allowing the formation of a thread balloon is left within the bell between the thread inlet and the thread outlet opening.
  • the thread outlet opening is provided with a guide element projecting inwards into the bell.
  • the shape of the thread balloon being formed can be changed without the shape of the bell itself having to be changed.
  • the guide element ensures on the one hand that the thread balloon maintains a distance from the inner wall of the bell and does not lie against it, while on the other hand the diameter with which the thread rotates and is excited to form the balloon is reduced.
  • the distance of the inner inlet opening of the guide element with respect to the axis of rotation of the bell is adjustable. This setting can be carried out by changing the position of the guide element and / or by exchanging the guide element. This makes it possible to adapt the shape of the thread balloon to the material to be spun in each case and to the other spinning conditions and in particular also to the speed.
  • the thread inlet is incorporated in a stationary bearing journal on which the essentially tubular bell is mounted.
  • the spinning device shown only schematically in Fig. 1 contains a drafting system, of which only the pair of delivery rollers (10) is indicated.
  • the spinning device also contains a driven spindle (12) which carries a bobbin (11) on which a thread is wound.
  • a bell (13) is arranged coaxially with the spindle (12) and engages over the coil (11).
  • the bell (13) has a bearing pin (21) with which it is mounted in roller bearings (22, 23) of a bracket, not shown.
  • the bearing pin (21) has an axial bore which forms a thread inlet (14).
  • the thread (20) running through the thread inlet (14) is guided through a thread outlet opening (16) out of the interior of the bell (13) to the outside of the jacket (15) of the bell (13).
  • the thread (20) runs in coils up to the lower edge of the bell, from where it is wound onto the spool (11).
  • the bell (13) is freely rotatable in the illustrated embodiment and is dragged by the thread (20). In a modification of the illustrated embodiment, it can be provided that the bell (13) is driven and / or braked in the region of its bearing pin (21).
  • the thread (20) runs without guidance in a free space, so that a thread balloon (17) is formed.
  • the size of the thread balloon (17) depends on the axial arrangement of the thread outlet opening (16) and on the speed.
  • the bell (13) in its jacket (15) is provided with a plurality of thread outlet openings (16) arranged in axially different positions.
  • the embodiment according to FIG. 2 corresponds in principle to the embodiment according to FIG. 1.
  • a bell (13) which overlaps the spindle (12) and its spool (11).
  • the bell (13) has an essentially tubular, stepped shape and is mounted with its end facing the drafting system on a stationary bearing journal (19) by means of roller bearings (24, 25).
  • the bearing journal (19) is provided with an axial bore, which serves as a thread inlet (14).
  • the jacket (15) of the bell (13) is provided with a thread outlet opening (16) at an axial distance from this thread inlet (14).
  • a tubular guide element (18) is inserted into the thread outlet opening (16) and protrudes inwards into the interior of the bell (13). As shown in Fig. 2, a space is also left between the end of the thread inlet (14) and the thread outlet opening (16) or the guide element (18), in which a thread balloon (17) is formed.
  • the guide element (18) ensures that the thread balloon (17) does not adhere to the inner wall the bell (13) puts on.
  • the inlet of the tubular guide element determines the speed at which the thread balloon (17) rotates due to its distance from the axis of rotation of the bell (13).
  • the circumferential speed can be varied by lengthening or shortening the radial extent of the guide element (18).
  • the axial length of the guide element (18) is adjustable and / or interchangeable in the bell (13) so that it can be replaced by guide elements (18) of different axial extension.
  • the end of the thread guide channel forming the thread inlet (14) is axially adjustable. Starting from the embodiment according to FIG. 3, the position of the entire journal (19) can be changed. In a modification of the embodiment according to Fig. 1 or Fig. 2 it is provided that the bearing pin (21) or the bearing pin (19) contains an insert forming the thread guide channel, which can be adjusted telescopically in the axial direction.
