Definitions

  • the present invention relates to a spinning device, in particular a rotor spinning device or air-jet spinning device, with a plurality of preferably self-sufficient work stations, each of which has a spinning station for producing a thread and a winding station for winding the thread on a cheese, the winding station having a tube holder for receiving a tube, a
  • the winding roller for driving the sleeve or the cheese and a traversing device for laying the thread on the cheese comprises and the spinning station has several individual drives and / or the winding station at least for the winding roller and the traversing device each have a single drive, as well as a method for piecing a thread in a preferably self-sufficient working station of a spinning device with a feed thread which is fed to the spinning station with a handling device for piecing a thread and wherein the spun thread is transferred to an empty tube.
  • a textile machine producing cross-wound bobbins which has a large number of similar, largely self-sufficient work stations and open-end spinning devices for the production of yarns, the yarn parameters of which are individually adjustable, as well as a service unit which can be moved along the work stations and is equipped with an auxiliary thread feed device, which has a service unit that Provides empty tube change for piecing the job required auxiliary thread. It is provided that the auxiliary thread delivery device of the service unit is designed to receive at least two supply bobbins with different threads and that one of these threads can be provided by the auxiliary thread delivery device as an auxiliary thread.
  • the disadvantage here is that the threads of the pre-winding must be adapted to the threads to be spun. If other threads are to be processed on the textile machine, the supply bobbins must also be replaced. In addition, it must always be ensured that there is a sufficient length of thread on the supply bobbins to be able to carry out the piecing process. Empty, almost empty or incorrect supply bobbins must be replaced. This is maintenance-intensive and can be faulty. In particular in modern spinning machines, in which several different threads can be spun, many different auxiliary threads must be kept in the service unit in order to be able to spin on all the spinning positions.
  • the object of the present invention is thus to remedy the above-mentioned disadvantages and to provide a piecing thread suitable for the respective job.
  • the object is achieved by a spinning device and a method for piecing a thread in a work station of a spinning device with the features of the independent claims.
  • the present invention relates to a spinning device, in particular a rotor spinning device or an air spinning device, with a plurality of preferably self-sufficient work stations, each of which has a spinning station for producing a thread and a winding station for winding the thread on a cheese.
  • the winding station comprises a tube holder for receiving a tube or the cheese, a winding roller for driving the tube or the cheese and a traversing device for laying the thread on the tube or the cheese.
  • the spinning station and / or the winding station have several individual drives, an individual drive being provided at the winding station at least for the winding roller and the traversing device.
  • a sliver is broken up into individual fibers and fed to a rapidly rotating spinning rotor.
  • the rotor spinning machine preferably has an individual drive for a feed device for fiber material from a fiber sliver into the work station, for an opening roller for breaking up the fiber material, for the spinning rotor for producing a thread and / or for a withdrawal device for withdrawing the thread from the spinning rotor.
  • the fibers are collected in the spinning rotor and drawn off again as a thread.
  • the withdrawal takes place with take-off rollers of the take-off device, which convey the thread at a predetermined speed.
  • the thread is then fed to the traversing device and guided back and forth in front of the rotating sleeve or cross-wound bobbin and wound onto it.
  • a piecing thread or feed thread is held in the rotating spinning rotor and pulled out of the spinning rotor together with the fibers that have accumulated on it.
  • a sliver is drawn in a drafting system and the thin sliver obtained is guided through an air-jet nozzle.
  • the fibers are twisted by an air vortex and thus form a thread. Similar to rotor spinning, this thread is drawn off with draw-off rollers and, with the help of the traversing device, is wound crosswise onto a tube or onto a cheese.
  • a piecing thread is inserted into or through the air-jet nozzle. The fibers drawn in the drafting system are connected to the piecing thread and conveyed and drawn off together through the air-jet nozzle.
  • the spinning device is assigned a feed thread device suitable for piecing the thread. This makes it possible to carry out the piecing process without a thread on the bobbin is used. In particular, if there is only one empty tube at the work site, a corresponding feed thread device is required.
  • the invention proposes that at least one feed thread device with a feed thread suitable for piecing the thread onto an empty tube is assigned in a stationary manner to each work station, the feed thread being stored independently of the spun thread.
  • each work station can start the piecing process on an empty tube without having to wait for a mobile service device.
  • the feed thread is present at every work station and can be introduced into the spinning rotor or the air-jet nozzle.
  • a feed thread device can be arranged in a service device that patrols along the spinning device and is delivered to the work site for piecing or filling up the feed thread device when required.
  • one feed thread device is provided for two adjacent work stations.
  • the feed thread device is positioned, for example, centrally between two adjacent workplaces and thus can serve both workplaces with one feed thread.
  • the feed thread is stored in the feed thread device independently of the spun thread.
  • the feed thread device thus does not correspond to a conventional thread store, which is provided for length compensation between thread production and winding in many spinning devices, but represents an independent device in which one of the feed thread is stored, which is used in particular for piecing onto an empty tube when there is no thread for piecing from the cheese.
  • the feed thread is stored independently of the spun thread. This means that the thread does not run through the thread store during normal thread production.
  • the thread store is therefore not constantly filled and emptied again, but is only used when a thread is spun, in particular when the thread is to be spun onto a tube without thread winding.
  • the feed thread device has a thread store for storing a feed thread with a length for at least one, preferably at least three piecing attempts.
  • the thread store is thus able to carry out at least one piecing attempt.
  • the length of the feed thread enables several piecing attempts. Only after the feed thread has been used up is it necessary again for the thread store to be filled with another feed thread. This filling can be done, for example, with a mobile service device which patrols along the spinning device and detects when the thread store is no longer sufficiently filled. In this case, the service device can refill the stationary thread store at the work site, for example from an auxiliary spool that is carried along, by unwinding the thread from the auxiliary spool and introducing it into the thread store or winding it up on it.
  • the thread store is an auxiliary bobbin or a drum store.
  • a particularly simple embodiment of the thread store is an auxiliary spool on which the feed thread is wound and is unwound for piecing if necessary.

  • the mobile service device can also have a device with which the auxiliary spool can be rotated so that it can take over the feed thread.
  • the feed thread is wound crosswise on the auxiliary bobbin.
  • a corresponding traversing device can be provided, which is either arranged on each feed thread device or is delivered from the mobile service device.
  • a drum store can also be provided to accommodate the feed thread. This more complex device is able to take up the feed thread in such a way that it can be unwound again without any problems.
  • a drum store is usually self-propelled and causes a parallel or cross-wise laying of the feed thread wound on it.
  • a handling device is preferably available at each work station for piecing the thread with the feed thread and for transferring the spun thread to the empty tube.
  • the work station is thus self-sufficient in this respect as well, i.e. not dependent on a mobile service device or an operator for piecing.
  • a suction device is advantageously provided for sucking off a part of the spun thread at each work site. This makes it possible for the piece of thread which contains the piecer to be sucked off and disposed of via the suction device. This is particular This is advantageous when the piecing thread and the thread to be newly spun are not identical or the piecing does not meet the specified quality criteria, i.e. is too thick or too thin compared to the rest of the thread, for example.
  • the preferred spinning device now makes it possible for each work station to independently spin a new thread, even if a bobbin change has previously taken place and there is only an empty tube and no cross-bobbin that has started, from which the piecing thread could be used.
  • the work station is assigned a preparation device for preparing the feed thread for the next piecing process, in particular for preparing an end of the feed thread.
  • the preparation device can put the feed thread into a state in which it is ideally suited for the next piecing process and can grip the newly spun thread and pull it out of the spinning rotor or through the air-jet nozzle.
  • a positioning device for preparing the feed thread for a piecing process is assigned to each work station.
  • the positioning device positions the feed thread or the end of the feed thread at a point of the work station at which the feed thread can be reached by a handling device which is assigned to the work station. From there, the feed thread is picked up by this handling device and fed to the spinning station for piecing.
  • the spinning station has individual drives for a feed roller, an opening roller, a spinning rotor, a take-off roller and / or a drafting device.
  • the spinning position can thus work independently. This means that it can spin a thread independently of other jobs.
  • different speeds of rotation of the individual components of the spinning station are required in order to be able to create a successful piecing. This can be carried out particularly well with an autarkic spinning station at which the speeds of the corresponding components can be set individually.
  • the spinning device is assigned a movable service device which has a control device for checking the filling level of the thread store.
  • the control device can thus determine whether the stationary thread store on the spinning device has stored a sufficient thread length in order to be able to carry out a predetermined number of piecing attempts.
  • the service device has a thread supply store, for example an auxiliary bobbin, for filling the stationary thread store with a feed thread.
  • the service device can refill the stationary thread store from this thread storage store, which has a longer thread length than the stationary thread store.
  • the thread of the thread storage device is used for piecing a thread on the spinning device.
  • the movable service device carries a larger amount or length of feed thread and can thus refill the thread store so that the work station can work independently again.

  • the spinning of a thread onto an empty tube can thus take place independently of the presence of an operator or a mobile service device at the work site. It is therefore possible to work independently at the workplace without waiting times. The efficiency of the job can thus be increased significantly.
  • a feed thread with a length for at least one, preferably at least three piecing attempts is stored in the feed thread device. It is thus possible for at least one piecing attempt, preferably several piecing attempts, to be carried out before the feed thread device has to be refilled with a feed thread.
  • a handling device is assigned to each work station, with which the feed thread for piecing the thread is introduced into the spinning station and the spun thread is transferred to the empty tube.

  • the feed thread can be prepared electrically, for example, in that the end of the feed thread is thermally cleaned. Chemical substances that remove the impurities can also be used to prepare the end of the feed thread for the next piecing process.
  • the surface structure of the feed thread is changed depending on the thread to be spun. The surface structure can have a particular influence on the success of piecing. A more or less coarse or rough or hairy surface structure can be more suitable for binding the fibers of the newly spun thread to the feed thread than a particularly smooth surface structure. Depending on the thread to be spun, certain surface structures can, however, be more or less advantageous.

  • the feed thread can be held by the positioning device in a position in which it can be easily gripped by a handling device at the work station and used to apply a new thread.
  • the positioning device can provide that a certain length of the feed thread protrudes beyond a predetermined clamping point in order to make a correct length of the feed thread available for piecing. In this case, the handling device no longer has to correct the length of the feed thread in order to be able to achieve piecing.
