Definitions

  • the invention relates to a method for operating a winding device of a textile machine producing cross-wound bobbins according to the preamble of claim 1 and to a device according to claim 5.
  • the thread end reserve of the cheese is usually formed by first unwinding some of the cross-wound thread windings from the coil body after the coil body has been completed and then rewinding it as a parallel winding either on the surface of the coil or on the tip of the cheese tube.
  • an operating unit that can be moved along the workstations of a cheese-making machine, after a cheese has been completed, picks up the thread wound on the package surface with its suction nozzle, unwinds a certain amount of thread from the cheese and stores it temporarily in the suction nozzle.
  • the thread running from the cheese to the suction nozzle is deflected by guide means on the suction nozzle beyond the end face of the cheese and transported into the area of a thread guide element pivotably mounted on the bobbin frame.
  • the thread guide element held in the rest position by a spring element, is actuated by the operating unit to create a thread end reserve.
  • a switching lever arranged on the control unit pushes a thread guide contour of the thread guide element close to the gusset formed by the thread package and the bobbin tube and ensures that the thread is wound onto the tip of the cheese tube as a thread end reserve.
  • the thread between the sleeve and the suction nozzle is taut due to the suction flow present in the suction nozzle of the operating unit and is wound onto the sleeve in relatively tight windings.
  • a bobbin changing carriage which has, inter alia, a suction nozzle, a bobbin drive and a thread guide device designed like a spindle.
  • the suction nozzle is swiveled into the area of the cheese surface in this bobbin changing carriage and the bobbin is rotated in the unwinding direction by the bobbin drive.
  • the suction nozzle picks up a certain amount of thread from the thread that has accumulated on the surface of the bobbin and temporarily stores this amount of thread.
  • the thread guide designed as a spindle is then pivoted into the strand of thread extending between the cheese and the suction nozzle and the cheese is rotated again in the winding direction, the thread being pulled out of the suction nozzle.
  • the thread is guided down from the bobbin surface, drawn as a tendon over the cross-bobbin flank and then fixed in parallel windings on the cross-bobbin surface.
  • Winding units of textile machines producing cross-wound bobbins are known, which are equipped with a winding unit's own device for creating a thread end reserve.
  • These known winding units have a thread traversing device with a thread guide which is arranged on a machine-long rod which, like the bobbin drive roller of the winding unit, is acted upon by a group drive arranged in a machine end frame of the textile machine.
  • a pivotably mounted guide bar provided with a guide notch is provided which extends over the entire width of the bobbin.
  • This spring-loaded guide bar is fixed in its rest position during the winding process by a controllable locking mechanism and, when the cheese has reached a predeterminable diameter, is swiveled open so that the thread is lifted out of the thread guide of the thread traversing device and on the guide bar in the direction of a bobbin flank arranged guide notch is shifted.
  • the thread sliding into the guide notch runs onto the cheese in parallel windings and forms a thread end reserve before it is separated by an associated thread cutting device.
  • the invention is based on the object of developing a method and a device that enables the creation of a cheese with a proper, safe thread end reserve during the winding process. That is, to create a method and a device in which, when creating a thread end reserve, unwinding and re-winding a thread end from a cheese, in particular with the aid of an operating unit, can be dispensed with.
  • this object is achieved by the method described in claim 1 or by the device described in claim 5.
  • the method according to the invention which is preferably used in winding units that have a bobbin frame for freely rotatable holding of a cheese, a single-motor-driven bobbin drive roller, a single-motor-driven, defined controllable thread traversing device and a winding unit's own thread storage device, has the advantage that the thread end reserve is already at the end the "regular" winding process can be carried out by the winding unit itself, that is, it does not have to wait until an operating unit moves to the winding unit, unwinds thread from the cheese and rewinds it again in parallel windings.
  • the thread storage nozzle By activating the thread storage nozzle, which is inherent to the winding unit and can be subjected to negative pressure, it is also ensured in a simple manner that the thread is wound with a sufficiently high thread tension while this thread end reserve is being created, since the thread reserve created due to the parallel windings is immediately subjected to negative pressure during winding
  • the thread storage nozzle is taken up as a thread loop and the thread is kept taut at all times.
  • the thread in the course of creating the thread end reserve by the thread guide of the thread traversing device is initially moved back briefly over one of the bobbin flanks of the cheese and immediately onto the bobbin surface, where the The thread is then set in parallel windings on the bobbin surface of the cheese.
  • Such a method ensures on the one hand that the thread extends over one of the bobbin flanks in the form of a tendon and is therefore easy to grip during further processing of the cheese, and on the other hand it ensures that the thread reserve is fixed sufficiently firmly on the bobbin even during the transport of the cheese is.
  • the thread as set out in claim 4, is fixed with three parallel windings on the bobbin surface of the cheese with a crossed bobbin diameter of, for example, 350 mm.
  • the thread is secured sufficiently securely to the bobbin surface of the bobbin while the cheese is being transported, and can also be detached at any time if necessary.
  • the winding device of the textile machine producing cross-wound bobbins for carrying out the method according to the invention has, as described in claim 5, a bobbin frame for freely rotatable holding of a cheese, a bobbin drive roller that can be acted upon by an individual drive for rotating the cheese, a single motor-driven, defined controllable thread traversing device and a defined Switchable thread storage nozzle, the mouth of which is arranged in the area of the path of the thread.
  • the thread storage nozzle is in turn connected to a sub-source and, if necessary, can be subjected to negative pressure, for example by appropriate control of a valve.
  • the negative pressure in the area of the mouth of the thread storage nozzle acts on the passing thread in such a way that excess thread length, which inevitably occurs on winding units with constant thread delivery when creating parallel windings, is immediately sucked into the thread storage nozzle as a thread loop, thus keeping the thread taut becomes.
  • FIG. 1 one half of an open-end spinning machine known per se is indicated and marked with 1.
  • Such spinning machines have a large number of work stations 2, each of which is equipped with a spinning device 3 and a winding device 4.
  • sliver 6 is spun into threads 7, which on the Winding devices 4 are wound into cross-wound bobbins 8.
  • the winding devices 4 are each equipped with a bobbin frame 9 for rotatably holding a cheese 8 or an empty tube and with a winding drum 11 that can be driven by a single motor for rotating the cheese 8.
  • these have for example in the DE 101 39 072 A1 largely self-sufficient workplaces 2 described, each via a single-motor-driven thread traversing device 18, a single-motor-driven thread take-off device 54, a workstation's own
  • Suction nozzle 14 a piecing element 20 and a thread storage nozzle 60.
  • the open-end spinning machine 1 also has a bobbin transport device 12 for disposing of the cross-wound bobbins 8 completed on the bobbin devices 4.
  • a service unit (not shown), for example a so-called changing and cleaning trolley, can also be displaceable on a guide rail 13 and a support rail 15.
  • Such service units intervene automatically when a need for action arises at one of the work stations 2.
  • Such a need for action exists, for example, when a full cheese is to be exchanged for a new empty tube at one of the work stations 2.
  • the Fig. 2 shows in perspective representation and on a larger scale one of the in Fig.1 schematically indicated work station 2 of an open-end rotor spinning machine 1.
  • Such jobs 2 have, as above with reference to Fig.1 already explained, including via an open-end spinning device 3 and a winding device 4.
  • a piecing element 16 is arranged in the area of the so-called thread take-off tube 21 of the open-end spinning device 3, which takes over the thread 7 retrieved by the suction nozzle 14 from the cheese 8 after a thread breakage and prepares the thread end for re-spinning .
  • such workplaces 2 have a thread withdrawal device 54, which both removes the spinning thread 7 from the open-end spinning device 3 during regular spinning operation and ensures a defined return of a prepared thread 7 into the open-end spinning device 3 during re-spinning.
  • the winding device 4 has a bobbin frame 9 for rotatably holding the cheese 8, a winding drum 11 that can be acted upon by a reversible individual drive 56, and a thread traversing device 18 that is driven, for example, by means of a stepping motor 57. Furthermore, such self-sufficient work stations 1 each have a pivotably mounted suction nozzle 14, which is adjustable by means of a stepper motor 58 between a thread take-up position located in the area of the winding device 4 and a thread transfer position located in the area of the spinning device 3.
  • Each of the work stations 2 also has a thread monitor 26, a waxing device 17 and a thread storage nozzle 60 which can be subjected to a defined negative pressure and which is used on the one hand during the start-up of the work station 2 and on the other hand when creating a thread end reserve 10. That is, the thread storage nozzle 60 stores a thread end reserve 10 of excess thread length both during start-up of the work station 2 and during creation, thereby ensuring that the thread 7 is always wound with a correct winding tension.
  • both the thread storage nozzle 60 and the pivotably mounted suction nozzle 14 are connected to a machine's own negative pressure network 19, the negative pressure source of which is identified by the reference number 30.
  • the suction nozzle 14 and the thread storage nozzle 60 are connected to the negative pressure network 19 of the textile machine 1, for example each via a connection line 22 or 23.
  • a closure means 24 is integrated in the connection line 22 and a closure means 25 is integrated in the connection line 23, the closure means 24 and 25 being connected via control lines 27, 28 to a control device 29 that is preferably internal to the workstation.
  • Fig. 3 shows a completed cheese 8, that is, a cheese with a thread end reserve 10, which was created according to the method according to the invention.
  • some parallel windings 32 preferably three, are arranged on the coil surface 34.
  • thread tendon 31 which can be easily recognized by the operating personnel and which is easy to handle for detaching the thread end reserve 10.
  • the bobbin surface 34 is displaced so that a thread tendon 31 is formed, which is then fixed by the parallel windings 32.
  • the control device 29 When this thread end reserve 10 is created, the control device 29 simultaneously actuates the closure means 24 in the sense of "opening" and thus connects the thread storage nozzle 60 to the vacuum network 19 of the textile machine 1 via the line 22. The then present at the mouth of the thread storage nozzle 60 acts on the thread 7 running up on the cheese 8 so that any excess thread length that is created is immediately sucked into the thread storage nozzle 60 as a thread loop and the thread is thus kept taut at all times.
