Definitions

  • the present invention relates to a method for piecing a thread in a spinning rotor of an open-end spinning device, in which the fibers are fed into the spinning rotor after the thread has been returned to the spinning rotor, and to an apparatus for carrying out the method.
  • the thread returned to the spinning rotor is deposited on 20% to 40% of the inner circumference of the spinning rotor and the abruptly released fiber mass corresponds to 30% to 50% of the fiber mass that is present in a fiber ring during the normal spinning process. In this way, the thick point in the area of the thread end is kept within acceptable limits, without a too weak thin point subsequently occurring at the same time.
  • the manner in which the increased amount of fibers M is provided in the spinning rotor 3 at the time of piecing is irrelevant to the invention.
  • a first exemplary embodiment is explained below with reference to FIGS. 4 to 6.
  • the inside of the spinning rotor 3 is fed in a conventional manner with the aid of a delivery device 1 and a disintegration roller 2 to a fiber sliver 4 which is dissolved in individual fibers 40, where the individual fibers 40 enter the collecting trough and form a fiber ring R.
  • the delivery device 1 has a driven delivery roller 10 and a feed trough 11 which resiliently supports it.
  • a slide stop 23 is arranged in the immediate vicinity of the film 21 on the side of the feed trough 11 facing away from the delivery roller 10, which prevents the feed trough 11 from sliding beyond the usual frame. If a pressure is exerted on the feed trough 11 in front of the clamping area 12 in the sliver transport direction, then when the feed trough 11 has reached the sliding stop 23, this pressure is converted into a pivoting movement of the feed trough 11.
  • a thread end E is now inserted into the thread take-off tube 30, which is sucked into the spinning rotor 3 due to the negative pressure prevailing in the spinning rotor 3 and which is generated by the rotating spinning rotor 3 Centrifugal force in the collecting trough of the spinning rotor 3.
  • the thread monitor 31, around the sensor 310 of which the returned thread end E is guided signals the renewed presence of the normal spinning voltage, as a result of which the electromagnet 55 is de-energized.
  • the plunger 54 now releases the clamping lever 5, the clamping end 52 of which completely releases the fiber sliver 4 by the action of the compression spring 53 and immediately thereafter the feed trough 11 with the fiber sliver guide funnel 51.
  • a suction line can open as the thread store 6 between the delivery device 1 and the opening roller 2, the suction line facing the sliver 4 at a short distance from it End can have a sieve and which can be effective or ineffective depending on a response of the thread monitor 31. For example, if a thread break occurs, fibers are sucked in, which are released again when spinning on (e.g. by reversing the air flow), whereby a timer can be used to ensure that the suction or blowing air is only effective for as long as is absolutely necessary.
  • the fiber storage 6 is arranged in the region of the fiber beard in continuation of the wall of the housing 20 surrounding the opening roller 2 and can be released by a movable fiber beard support.
  • the fiber beard support is formed by a pivotable feed trough 11. It is also possible, however, to provide a fiber beard support which can be pivoted in the circumferential direction of the housing wall, which enables the fiber beard to escape from the area of influence of the opening roller 2 and which, on the other hand, can quickly bring the fiber beard back into the area of action of the opening roller 2, in order to suddenly release the stored one To reach the amount of fiber.
  • a fiber storage 6 is formed between the surface of the feed trough 13 facing the opening trough 13 and the opening roll 2 itself when the pivoting movement of the feed trough 13 exceeds the usual extent.
  • a single control element serves both to control the fiber storage 6 and to control the clamping of the sliver 4.
  • a clamping member 7 is provided, for example, which cooperates with a stop 130 provided on the feed trough 13.
  • the clamping member 7 is formed by the plunger of an electromagnet 70, which is controlled as a function of the response of the thread monitor 31 (FIG. 4).
  • the clamping lever 8 provided for clamping the sliver 4 can be controlled independently of the clamping mechanism 7 and with a delay that can be preset by interposing a suitable timing element (not shown).
  • a clutch 9 is assigned to the delivery roller 10.
  • the clutch 9 has on the drive shaft 100 of the delivery roller 10 two freely rotatable drive wheels 90 and 91, with which a driving wheel 92 connected to the drive shaft 100 in a rotationally fixed manner can alternately be brought into engagement.
  • the driving wheel 92 has a circumferential groove 920 into which an adjusting lever 93 engages with its adjusting element 930.
  • the actuating lever 93 is connected to the armature 940 of an electromagnet 94, which is electrically connected to the thread monitor 31 via a control element 95.
  • the clutch 99 is disengaged via the control element 95, so that the delivery roller 10 is stopped.
  • the clutch 99 is engaged again via the control element 95, but at the same time the driving wheel 92 is brought into engagement with the drive wheel 91, so that the delivery roller 10 from the motor 98 via the drive connection 970, 971, 97, 96, 911, 910, 91, 100 is driven at an increased speed, as a result of which individual fibers F get into the spinning rotor 3.
  • the fiber delivery quantity is normalized again by switching drive wheel 92 from control element 95 (time element) to drive connection 98, 970, 971, 97, 96, 901,. 900, 90, 100, 10 is produced.
  • the delivery device 1 can thus be driven briefly at an increased delivery speed and then at a normal delivery speed, so that the increased amount of fibers M (FIG. 3) is also applied to such a device returned thread end E can be fed in such a way that it is available in the area where the thread is attached.
