Definitions

  • the present invention relates to a method for exchanging a full bobbin for an empty tube in a bobbin device of an open-end spinning device, in which the open-end spinning device is stopped and the fiber collecting surface is cleaned when the specified bobbin size is reached, and a device for carrying out this method.
  • the object of the present invention is therefore to provide a method and a device which enable the thread to be wound onto the empty tube in a simple manner and without the aid of additional devices after the bobbin change and cleaning of the spinning station.
  • the thread is expediently returned from the full bobbin still in the winding device to the open-end spinning device and the thread is drawn off after piecing and removed with the piecing device and only then the full one Reel replaced with the empty tube and then transfer the thread supplied by the open-end spinning device to the empty tube and the thread end extending into the discharge is separated.
  • the piecing may also be advantageous to carry out the piecing with the help of empty tubes with applied starter windings in order to better adapt to the material to be spun.
  • the full bobbin is exchanged for an empty tube provided with starter windings and the spinning takes place with the aid of these starter windings and then both the thread supplied by the open-end spinning device and the thread which is still as Starter turns on the empty tube thread is removed.
  • the targeting of the thread after the piecing takes place first by the winding device, that the thread section is then unwound again with the piecing device and is discharged together with the thread supplied by the open-end spinning device.
  • the full bobbin is first ejected from the winding device and the thread path of the newly spun and removed thread is extended beyond the winding device and then the new sleeve is inserted into the winding device, whereupon the thread path in the direction of newly inserted sleeve is deflected so that the thread partially wraps around the sleeve. Since the thread run is extended beyond the winding device after the full bobbin has been ejected and before the empty tube has been inserted, the newly spun thread and the thread fed to the outlet are located between the drive roller of the winding device and the tube. By deflecting the thread in the direction of the sleeve, a partial looping of the sleeve is achieved, so that it takes the thread with it as it rotates, particularly when the surface of the sleeve is rough.
  • the thread of the bobbin is presented in that after the bobbin change, the thread path of the newly spun and removed thread - with respect to the direction of transport of the thread supplied by the open-end spinning device - is extended so far that the thread path the path of a winding device provided thread catcher crosses.
  • the sleeve resting on the drive roller is driven in such a way that in the region of the clamping line of the drive roller and sleeve, their direction of movement coincides with the thread transport direction.
  • a thread catching device provided on the winding device which can catch the thread only in the area of the sleeve facing away from the clamping line, thus moves in a direction opposite to the thread transport direction, so that the thread relaxes when it is taken over by the sleeve. Since the thread still does not change during the formation of the reserve turns, the winding speed is also lower than the speed of the thread supplied by the open-end spinning device.
  • the excess length of the subsequently supplied thread is advantageously stored during the onset of the winding, which process includes the formation of the reserve turns, and is used up again after the start of the bobbin build-up in the construction of the normal bobbin windings.
  • the thread supplied after the severing of the thread section with the piecing can be longer than for the thread reserve, the thread for the transfer and the formation of a thread reserve is advantageously not in connection with the transfer of the thread supplied by the open-end spinning device to the newly inserted sleeve required excess thread length is cut off and removed.
  • the thread section containing the piecing is preferably removed as a loop.
  • An auxiliary drive for the bobbin, a thread suction device serving as a discharge device and a thread separation device assigned to the thread suction device are used to carry out the method according to the invention.
  • the thread-aspirating device has the task of removing the thread section with the piecing device, whereupon the latter is severed with the aid of the thread-separating device, the piecing material that is created during piecing being eliminated.
  • the separated thread section is then removed by the thread suction device.
  • the thread suction device now moves into such a position that the thread can be transferred to the empty tube, whereby the excess thread length can be cut off by means of the thread separation device, which is then also removed by the thread suction device.
  • the mouth of the thread suction device is movable from a thread take-up position between the open-end spinning device and the winding device into a thread transfer position for transferring the thread to the empty tube.
  • the mouth of the thread suction device is movable from the thread take-over position to the side of the empty tube facing away from the thread feed side, it being possible in a further embodiment that the mouth of the thread suction device can be moved perpendicularly to the axis of the sleeve from its thread transfer position in such a way that the to the mouth of the thread suction device extending thread partially wraps around the sleeve.
  • the thread suction device can be switched over to a compressed air source, so that the thread end can be blown against the empty tube.
  • the mouth of the thread suction device can be brought from the thread take-up position into such a thread transfer position that the thread path crosses the path of a thread catching device provided on the winding device.
  • the thread separating device is preferably arranged in the thread suction device.
  • the thread suction device is expediently designed as a closure element for the thread suction device, since in this way neither a separate closure element nor a separate control element is required to control the vacuum acting in the thread suction device.
  • the thread suction device is assigned a thread feeder for transferring the thread fed to the thread suction device to the empty tube.
  • this thread guide which can be moved parallel to the bobbin, can be brought to the discharge end of a centering spindle of reduced diameter, which forces the thread from any thread run into a fixed thread run in a particularly simple manner.
  • a thread store is arranged in the thread run in front of the bobbin.
  • the subject of the invention does not require replaceable starter coils and is simple in construction, simple in function and in control and makes it possible to use bobbins without the piecing or other connections which inevitably usually occur when changing the bobbin or other connections which replace these piecing, e.g. B. knots, etc. In this way, a yarn is produced with much less work and time than before, which does not contain the known defects which would otherwise result from the piecing coinciding with the start of the bobbin.

Then the suction tube 20 is brought from its rest position shown in the position 20 a, in which the mouth 26 is in the immediate vicinity of the full coil 32. The auxiliary drive roller 24 is brought into contact with the spool 32 by pivoting the lever 25 and is now driven in the unwinding direction. The mouth 26 of the suction tube 20 now receives the end of the thread 35 unwound from the bobbin. The thread 35 is now sucked into the suction tube 20 in accordance with the unwinding speed of the bobbin and exits in the form of a chord from the longitudinal slot of the suction tube 20.

  • the direction of rotation of the coil 32 is reversed again with the aid of the auxiliary drive roller 24.
  • the thread 35 is thus sucked into the thread suction device 4 due to its decreasing tension in the form of a loop and is continuously removed, this loop being fed from the thread returned by the bobbin 32 and the thread supplied by the spinning device.
  • the sleeve 38 is lowered onto the drive roller 30 by releasing the coil arm 31, so that the sleeve 38 is driven in the winding direction.

  • the thread 35 is thus wound on the sleeve 38.
  • the length of the thread section located in the thread suction device 4 is now limited by actuating the thread separation device 41 again, so that the position of the thread separation device 41 in the thread suction device determines the length of the free thread end at the sleeve end.
  • the thread extending from the spinning device to the thread catching device 37 moves ever further to the center of the sleeve due to the thread tension until it is gripped by the traversing thread guide 16.
  • the thread forms several turns as a thread reserve.

  • a thread guide 5 is provided in the thread path between the open-end spinning element and the winding device 3, which along the bobbin 32 (or the sleeve 38 ) is movable and to which a controllable release device 50 is assigned, by means of which the thread 35 can be ejected from the thread guide 5.
  • the thread guide 5 is designed such that it can receive the thread 35 between the open-end spinning element and the mouth 40 of the thread suction device 4 located in the thread take-up position 40a. When the mouth 40 assumes its thread transfer position 40b, the thread path is thus precisely fixed.
  • the thread guide 5 By axially adjusting the thread guide 5 relative to the sleeve 38, the thread guide 5 is brought from its shown position, in which it catches the released thread 35, into a second position 5a, in which it holds the thread 35 in the area of the sleeve 38 reserved for the reserve windings feeds.
  • the thread guide 5 By displacing the thread guide 5 in the direction of the center of the sleeve and then actuating the release device 50, the thread 35 is ejected from the thread guide 5 in the working area of the traversing thread guide 16 and thus released and gripped by the traversing thread guide 16.

  • the thread When the thread leaves the suction tube 20 through its slot, it reaches the centering spindle 51, which feeds the thread 35 by rotation in one direction of its centering groove 52. After piecing is complete, the centering spindle 51 is rotated in the opposite direction, so that the thread 35 migrates to the shedding end 53 of the centering spindle 51 and is dropped there. Before this, however, the thread guide 5 has been moved to the discharge end 53 of the centering spindle 51 and catches the thread 35.

There is also no exposed end of the thread, but a small loop that allows the thread reserve to be easily removed from the bobbin for connection to the next bobbin during further processing.
  • the plane of movement of the thread suction device 4 is expediently chosen so that it is located in the area of the thread reserve. In this way it is achieved that the thread end, which is withdrawn from the thread suction device 4 after the separation process, when winding immediately before ejecting the bobbin 32 passes the end of the winding over to the sleeve, where there are still one or two turns above the thread reserve formed at the beginning of the bobbin build.

  • the thread separation device 41 is arranged in the thread suction device 4. Since the separation process takes place extremely quickly, even a temporary interruption of the negative pressure acting in the thread suction device 4 does not matter.
