Definitions
- the present invention relates to a method for winding a thread on a textile machine producing cross-wound bobbins according to the preamble of claim 1 and to a textile machine producing cross-wound bobbins according to the preamble of claim 4.
- a cross-wound producing textile machine which has a plurality of jobs.
- a thread is produced by means of an open-end spinning device, which thread is laid on a cross-wound bobbin by a single-motor-driven thread-changing device.
- a rematching process is initiated to remedy it.
- Continuing the laying of the thread on the cheese causes a temporary occurrence of overlength of the thread. This is due to the different acceleration speeds of the individual motor driven components of the workstations.
- the thread temporarily stored in the thread storage device to compensate for the excess thread length occurring after re-spinning is of a smaller value than normal operation of the textile machine Having winding tension.
- the lower winding tension of the thread is due to the fact that the winding tension is generated during this phase only by the pending in the pneumatic yarn storage vacuum, with the result that when emptying the yarn storage device, the thread is wound in loose layers on the cheese to be produced.
- These loose thread layers lead to tees on the coil sides, which leads to lasting drainage problems of the thread in the further processing of the cheeses.
- the object of the present invention is to provide a method by which the laying of the yarn temporarily resulting from the yarn excess length is improved with a low winding tension in order to avoid losses of the yarn and the provision of a textile machine for carrying out the process.
- the Nennhub the Fadenchangier drove the work is shortened after the elimination of the thread interruption for the duration of winding a defined thread length on the cheese.
- the Fadenchangier By shortening the Nennhubes the Fadenchangier adopted a smaller laying width of the thread is achieved on the cheese, so that in the lower winding tension Wound yarn the occurrence of tees on the cheeses is largely avoided.
- the ceremoniesspulende defined thread length should be set so that they are achieved at the earliest with the complete emptying of the storage device and the achievement of the normal operation of the textile machine corresponding speeds of the drives. This ensures the achievement of a stable state of the winding tension for the transition to the normal operation of the textile machine.
- additional thread length can be wound to ensure that after emptying the thread storage device and the startup of all drives the job, which were restarted to carry out the process of repairing the interruption of the thread, for switching a stable and slightly increased winding tension is given by the reduced stroke on the nominal stroke of Fadenchangier pain.
- the Nennhub the Fadenchangier worn by about 5 mm to 40 mm, in particular by 10 mm to 30 mm, are shortened.
- the magnitude of the shortening of the stroke depends essentially on the ratio which exists between the ramp-up times of the drives of the components of the job, in particular between the thread take-off roller and the winding shaft.
- the ramp-up time of the drive shaft driving the turn turn be significantly dependent on the diameter of the cheese at the time the thread interruption, while the ramp-up time of the drive of the thread take-off roller can be regarded as almost constant.
- each workstation comprises a control device which reduces the shortening of the Nennhubes the Fadenchangier worn after the elimination of the thread interruption for the duration of winding a defined thread length controls the cross-wound bobbin.
- control device can reduce the nominal stroke of the thread switching device for the duration of at least the emptying of the thread storage device.
- the textile machine may comprise a device for determining the length of the thread wound up with a shortened stroke.
- the thread length on the speed or the step increments of the drive of the winding shaft whose speed or step increments is monitored by the control device, as well as from the respective current diameter of the cheese to be produced are derived.
- Figure 1 shows a perspective view of a job 1 an open-end rotor spinning machine, which, as known and therefore shown only schematically, via an open-end spinning device 2 for producing a thread 9 and a downstream in the direction of thread F
- Winding device 3 has. On this winding device 3, the thread 9 is wound into a package 8.
- the thread 9 produced in the open-end spinning device 2 is, as indicated, by a thread withdrawal device 27, the one driven by a single motor thread take-off roller 10 and an engageable with the thread take-off roll 10, from this frictionally entrained pressure roller 14, withdrawn from the open-end spinning device 2.
- the yarn 9 leaves the open-end spinning device 2 through a so-called yarn withdrawal tube 21, in the region of which a pivotally mounted piecing aid 16 is arranged, which after a yarn break is interrupted by a suction nozzle 4 from the cross-wound bobbin 8 retrieved thread 9 takes over and prepares the thread end for thread connection.
- a thread monitor 26, a mechanical thread storage device 7, a pneumatic thread storage device 12 and a waxing device 5 are arranged in the area of the thread running path.
- the pneumatic thread storage device 12 is formed as a discontinuous working memory, that is, the thread storage device 12 is completely emptied after each thread connecting operation.
- the yarn storage device 12 is acted upon by a vacuum source, not shown, with suction air.
- the winding device 3 consists, as usual, from a creel 22 for rotatably supporting a cross-wound bobbin 8, a preferably via a reversible single drive 19 driven winding shaft 23 and a Fadenchangier rally 24, which is driven for example via a stepping motor 20.
- Such work stations 1 have, as already mentioned, a suction nozzle 4 which, by means of a stepping motor 6, is defined between a thread take-up position lying in the region of the winding device 3 and one in the region of Spinning device 2 lying thread transfer position is adjustable.
- the individual stepper motors of the components of the workstation 1 are connected via various control lines to a control device, in the present exemplary embodiment to a workstations computer 25.
- a control device in the present exemplary embodiment to a workstations computer 25.
- the individual motor drives of the components of the workstations 1 are independently controllable.
- the control device may be designed as a central computer of the textile machine.
- the commissioning of the thread take-off roller 10, the Fadenchangier worn 24 and the winding shaft 23 is carried out taking into account temporally coordinated acceleration processes of the individual drives, which should take into account in particular the different moments of inertia and the traction of the operating components to be taken into account.
- the excess length of the thread 9 produced by the open-end spinning device 2, which are not wound by the cross-wound bobbin 8 due to the slow speed of the winding shaft 23 can, initially be cached, which is realized via the thread storage device 12.
- the problem occurring here is the reduced winding tension, which is present during the emptying of the thread storage device 12 after the yarn joining operation, since the winding tension of the thread 9 is generated during this period only by the upcoming in the thread storage device 12 negative pressure.
- the nominal stroke of the thread switching device 24 is shortened, at least for the duration of the complete emptying of the thread storage device 12.
- deductions at the coil edges due to the lower winding tension of the thread to be laid 9 can be largely avoided.
- beyond the defined thread length beyond additional thread length can be wound to ensure that after emptying the thread storage device 12 and the startup of all drives the job 1, which were restarted to carry out the process of repairing the interruption of the thread for the Switching from the reduced stroke to the nominal stroke of the thread-switching device a stable and slightly increased winding tension is given.
- the length of additionally wound with shortened nominal stroke thread 9 is between 1 and 10 m.
- the shortening of the nominal stroke can be between 5 and 40 mm, in particular between 10 mm and 30 mm.
