Definitions

  • the present invention relates to a spinning device, in particular a rotor spinning device or air-jet spinning device, with a large number 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 Winding roller for driving the tube or the cross bobbin and a traversing device for laying the thread on the cross bobbin and the spinning station has several individual drives and / or the winding unit each has an individual drive at least for the winding roller and the traversing device, as well as a method for spinning a thread in a preferably self-sufficient work station of a spinning device with a feed thread, which is fed to the spinning station with a handling device for spinning a thread and whereby 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 workstations and open-end spinning devices for producing yarns, the yarn parameters of which can be individually adjusted, as well as a service unit which can be moved along the workstations and is equipped with an auxiliary thread delivery device and which has one after a cross-wound bobbin When changing the empty tube, the auxiliary thread required for spinning the work area is provided. It is provided that the auxiliary thread delivery device of the service unit is designed to accommodate at least two supply spools 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 prewinding have to 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 is always important to ensure that there is a sufficient length of thread on the supply spools in order to be able to carry out the piecing process. Empty, almost empty or incorrect supply spools must be replaced. This is maintenance-intensive and can be subject to errors. Particularly 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 spinning points.
  • a spinning station which comprises an auxiliary thread spool, a cutting device, a splicing device, a first clamping device for the upper thread, a cutting device assigned to the splicing device, a pivotally mounted suction pipe and a thread storage.
  • the auxiliary thread is pulled off the auxiliary thread spool, guided through the cutting device and threaded into the spinning device and then manually guided through the pair of take-off rollers. If the auxiliary thread spool is empty or another thread is to be spun at the spinning station in the future, it must be replaced.
  • the object of the present invention is therefore to eliminate the above-mentioned disadvantages and to provide a piecing thread that is suitable for the respective workplace.
  • the task is solved by a spinning device and a method for spinning a thread in a workstation 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-jet spinning device, with a large number 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 unit includes a tube holder for holding 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 unit and/or the winding unit have several individual drives, with one individual drive being provided on the winding unit at least for the winding roller and the traversing device.
  • a sliver is broken down 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 sliver into the workstation, for an opening roller for opening the fiber material, for the spinning rotor for producing a thread and / or for a take-off device for pulling the thread from the spinning rotor.
  • the fibers are collected in the spinning rotor and drawn off again as thread.
  • the pulling-off 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 cheese 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 accumulate on it.
  • a sliver is stretched in a drafting system and the resulting thin sliver of fibers is guided through an air-jet spinning nozzle.
  • the fibers are twisted by an air vortex and thus form a thread.
  • This thread is similar to the Rotor spinning is drawn off with take-off rollers and wound crosswise onto a sleeve or cross-wound bobbin using the traversing device.
  • a piecing thread is inserted into or through the air spinneret.
  • the fibers stretched in the drafting system are connected to the piecing thread and conveyed together through the air spinneret and drawn off.
  • the spinning device is assigned a template thread device suitable for spinning the thread. This makes it possible to carry out the piecing process without using a thread on the spool. In particular, if there is only one empty tube at the workstation, a corresponding feed thread device is required.
  • the invention proposes that at least one template thread device with a template thread suitable for spinning the thread onto an empty tube is assigned to each workstation in a stationary manner, the template thread being stored independently of the spun thread.
  • each workstation can begin the spinning process onto an empty tube without having to wait for a mobile service device.
  • the template thread is available at every workstation and can be inserted into the spinning rotor or the air spinneret.
  • a template thread device can be arranged in a service device that patrols along the spinning device and is delivered to the work station for spinning or to refill the template thread device when necessary.
  • one feed thread device may also be provided for two adjacent workstations.
  • the template thread device is positioned, for example, centrally between two adjacent workstations and can therefore serve both workstations with a template thread.
  • the template thread is stored in the template thread device independently of the spun thread.
  • the feed thread device therefore 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 spinning onto an empty tube if no There is thread for spinning the cheese.
  • the template thread is stored independently of the spun thread. This means that during normal thread production the thread does not pass through the thread storage.
  • the thread storage is therefore not constantly filled and emptied again, but is only used when a thread is being spun, especially if the spinning is to take place on a tube without thread winding.
  • the template thread device has a thread storage for storing a template thread with a length for at least one, preferably at least three piecing attempts.
  • the thread store is therefore able to carry out at least one piecing attempt.
  • the length of the feed thread enables multiple piecing attempts. Only after the template thread has been used up is it necessary to refill the thread storage with another template thread. This filling can be done, for example, with a mobile service device, which patrols along the spinning device and detects when the thread storage is no longer sufficiently filled. In this case The service device can refill the stationary thread storage at the workstation, for example from an auxiliary spool carried along, by unwinding the thread from the auxiliary spool and introducing it into the thread storage or winding it up on it.
  • the thread storage is a drum storage.
  • a particularly simple version of the thread store that does not fall within the scope of protection of claim 1 is an auxiliary spool on which the feed thread is wound and, if necessary, unwound for piecing.
  • the auxiliary spool can be provided with a drive with which it can be rotated in order to accommodate the thread, which is supplied, for example, by the mobile service device.
  • 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. In order to enable trouble-free unwinding of the feed thread, it is advantageous if the feed thread is wound crosswise on the auxiliary spool.
  • 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 storage is provided to hold the template thread. This more complex device is able to pick up the template thread in such a way that it can be unwound again without any problems.
  • a drum storage is usually self-driven and causes the feed thread wound on it to be laid parallel or crosswise.
  • a handling device for spinning the thread with the feed thread and for transferring the spun thread to the empty tube is preferably present at each workstation.
  • the workstation is therefore self-sufficient in this respect, i.e. it does not rely on a mobile service device or an operator for piecing.
  • a suction device for sucking off part of the spun thread is advantageously provided at each workstation. This makes it possible for the piece of thread containing the piecing device to be sucked off and disposed of using the suction device. This is particularly advantageous if the piecing thread and the new thread to be spun are not identical or the piecing does not meet the specified quality criteria, for example if it is too thick or too thin compared to the remaining thread.
  • the preferred spinning device now makes it possible for each workstation to spin a new thread independently, even if a bobbin change has previously taken place and there is only an empty tube and no started cheese from which the piecing thread could be used.

  • the preparation device Through the preparation device, the template thread can be put into a state in which it is optimally suitable for the next spinning process and can grab the newly spun thread and pull it out of the spinning rotor or through the air spinneret.
  • each workstation is assigned a positioning device for providing the feed thread for a piecing process.
  • the positioning device positions the template thread or the end of the template thread at a point on the work site at which the template thread is handled by a handling device assigned to the work site is, is reachable. From there, the template 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 system.
  • the spinning station can therefore work autonomously. This means that she can spin a thread independently of other jobs. Particularly when spinning a thread, different speeds of the individual components of the spinning station are required in order to be able to create a successful piecing device. This can be carried out particularly well with a self-sufficient spinning station, where the speeds of the corresponding components can be adjusted individually.
  • the spinning device is assigned a movable service device which has a control device for checking the fill level of the thread storage.
  • the control device can thus determine whether the stationary thread storage on the spinning device has stored a sufficient thread length in order to be able to carry out a predetermined number of spinning attempts.
  • the service device has a thread supply store, for example an auxiliary spool, for filling the stationary thread store with a feed thread. If there is a need for additional piecing thread, the service device can refill the stationary thread storage from this thread storage, which has a longer thread length than the stationary thread storage. Additionally or alternatively, it is also possible for the thread of the thread supply store to be used to spin a thread on the spinning device.
  • the movable service device carries a larger quantity or length of feed thread and can thus refill the thread storage so that the workstation can work independently again can.

  • the template thread is made available either for an individual workstation or for neighboring workstations.
  • the spinning of a thread onto an empty tube can therefore be carried out independently of the presence of an operator or a mobile service device at the work site. This makes it possible for the workplace to work independently without waiting times. The efficiency of the workplace can thus be significantly increased.
  • a template thread with a length for at least one, preferably at least three piecing attempts is stored in the template thread device. It is therefore 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.
  • each workstation is assigned a handling device with which the feed thread for spinning the thread is introduced into the spinning station and the spun thread is transferred to the empty tube.

  • the end of the feed thread can also be prepared for the next piecing process using chemical substances that remove the impurities.
  • the surface structure of the template 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 may be better suited to binding the fibers of the newly spun thread to the template thread than a particularly smooth surface structure. Depending on the thread to be spun, certain surface structures can be more or less advantageous.
  • the template thread is positioned for a piecing process using a positioning device that is assigned to each workstation.
  • the template thread can be held by the positioning device in a position in which it is easily grasped by a handling device at the workstation and used to attach a new one Thread can be used.
  • the positioning device can provide that a certain length of the template thread protrudes beyond a predetermined clamping point in order to provide a correct length of the template thread for spinning.

After the thread storage takes up a limited amount of the feed thread, it must be checked whether the thread storage is sufficiently filled for the next spinning process(es). This can advantageously be done by the service device, which patrols along the spinning device.
  • the service device not only signals when the thread store needs to be supplemented, but is also able to refill the thread store, particularly if the length of the feed thread stored in the thread store is no longer sufficient for a predetermined number of piecing attempts.

While when using a conventional piecing thread, this piecing thread is either wound onto the cross-wound bobbin or is sucked off via the suction system, the reusable piecing element can be used multiple times for piecing. This results in little or no consumption of the piecing element. Even if there is a consumption of the piecing element, this is still so low that the piecing element can be used for a large number of piecing attempts.
  • the piecing element can, for example, be kept ready in a spool which accommodates a length of, for example, 1 to 10 meters of the piecing element. Due to the very low consumption, this length is sufficient for many piecing attempts. This means that it is not necessary to stock a large spool on which a conventional piecing thread is wound. It is sufficient that the piecing element is present at the workstation and can be inserted into the spinning rotor or the air spinneret. The piecing element is then pulled out again, together with the newly formed thread, from the spinning rotor or the air spinneret and then separated again from the newly formed thread.

In one surface structure, fibers adhere very easily to the spinning element in order to be able to remove the fibers and thus the newly spun thread from the spinning medium, i.e. the spinning rotor or the air spinning nozzle. With the other surface structure, the surface is smooth, so that fibers do not easily adhere to the piecing element and can easily detach themselves from it.
  • the surface structure of the piecing element can be changed, in particular mechanically, pneumatically, electrically and/or chemically. This allows the piecing element to be adapted to the specific conditions of the thread to be spun. In addition, the cleaning of the piecing element can be carried out particularly advantageously.
  • the surface structure of the piecing member has protruding and/or adjacent ends of fibers of the piecing member.
  • Protruding ends of fibers of the spinning element create a rough surface to which the fibers of the thread to be spun adhere well.
  • Adjacent ends of fibers of the piecing element allow for a smoother finish Surface that is easy to clean. Due to a variable surface structure, which can be influenced by the more or less abutment of the ends of fibers of the piecing member on the piecing member, the piecing member is able to be optimally adapted for both piecing and cleaning. In addition, this allows the piecing element to be better adapted to the piecing of different new threads, which may differ, for example in material or thread thickness.
  • a length of the protruding fibers of the piecing element can be changed mechanically, electrically and/or chemically.
  • the length of the protruding fibers in turn influences the surface roughness of the piecing element and thus on the properties for piecing and cleaning the piecing element.
  • Protruding fiber ends can have their length changed, for example by winding the piecing element more or less tightly. They can also be applied to the piecing element to a greater or lesser extent by chemical additives or electrical charges and fixed there permanently or for a limited time.
  • the piecing member is hollow and has openings from which ends of fibers of the piecing member protrude. Because the fibers protrude more or less long from the hollow piecing member, a different surface of the piecing member is created, which can be adapted to the different threads to be spun. In particular, if the length of the ends that protrude from the piecing element can be changed, the surface of the piecing element is, on the one hand, particularly suitable for piecing and, on the other hand, particularly suitable for cleaning.
