Definitions

  • the present invention relates to a spinning station of a spinning machine, which serves to produce a yarn from a fiber strand fed to the spinning station in a transport direction.

  • the intake manifold shown therein for receiving a short Garnabitess is also in the JP H09 157970A shown.
  • the service robot Since the service robot must first be moved to the respective spinning station before the piecing process and only one spinning station can be spun by a robot, the necessary piecing processes lead to considerable limitations of the spinning process.
  • the piecing operations in accordance with the cleaner cuts to be increasingly carried out in air-spinning machines contribute to a significant impairment of the productivity of the air-spinning machine.
  • the object of the present invention is therefore to propose a spinning station and a method for operating the same with the aid of which the piecing times can be shortened compared with the prior art, in particular after a cleaner cut.
  • the spinning station initially comprises a spinning unit with means for producing the yarn, wherein the means may be for example a rotor of a rotor spinning machine or the vortex chamber of an air spinning machine.
  • the means may be for example a rotor of a rotor spinning machine or the vortex chamber of an air spinning machine.
  • one of the spinning unit seen in the transport direction of the fiber strand or the yarn downstream extraction device for deduction of the yarn from the spinning unit is provided, which may comprise, for example, a yarn trapping leading take-off roller pair.
  • a yarn storage device arranged downstream of the removal device is provided for temporarily storing a yarn section. The term caching in this context, the fact that the yarn passes through the buffer during its transport to the winding device.
  • the spinning station comprises a sensor system for monitoring the fill level of the yarn store.
  • the sensor system is preferably placed in the region or the interior of the yarn store and is designed to detect the presence of a yarn at predefined locations of the yarn store or the length of the yarn section located in the yarn store.
  • the winding device for this is preferably in communication with a controller, which is fed with the data determined by the sensor , If the controller determines that the length of the yarn section present in the yarn store (or the yarn loop present in the yarn store) is below a minimum, the winding speed of the winding device is reduced until the length again corresponds to a defined minimum size. If said length exceeds a predetermined maximum, the winding speed is increased accordingly.
  • the spinning station comprises a return means, with the aid of which a yarn end, which is located after a yarn break within the yarn store, is traceable into the region of the spinning unit.
  • a spinning station is proposed, which is able to fix a yarn breakage regardless of its cause by the resulting yarn without the use of a service robot to be returned to the spinning unit and connected to the fiber structure (the individual process step will be in the following description in connection with the invention Method will be described in more detail).
  • the term "yarn breakage" in the context of the invention is intended to mean any desired or uncontrolled separation of a package-side yarn section from the fiber structure or a spinning unit-side yarn end leaving the spinning unit.
  • the return means comprises an air nozzle, with the aid of which a directed toward the spinning station air flow can be generated. With the aid of the corresponding air flow, it is possible to blow a yarn end located in the yarn store in the direction of the spinning unit. In this area, it can finally be sucked by the spinning unit and transported in the direction of the fiber strand, in order to supply it to the described piecing process. Such recirculation is particularly desired following the removal of a yarn defect, in which connection reference is made to the description of the process according to the invention.
  • the air nozzle is preferably in communication with a controller, which is also in communication with the yarn storage or associated with the yarn storage vacuum source. This makes it possible to deactivate the yarn storage during the return of the yarn end in the direction of the spinning unit, to preclude that the yarn storage prevents a return of the yarn end in the region of the spinning unit.
  • the sensor system comprises at least two spaced-apart sensors, with the aid of which the presence of the yarn in the region of the respective sensor can be detected.
  • the yarn store could comprise an elongate interior in which the yarn is held looped by means of a negative pressure. If the loop is located between the two sensors, which should be placed adjacent to one another in the longitudinal direction of the interior, the fill level of the yarn store corresponds to the desired value. On the other hand, if both sensors detect the respective presence of a yarn section, the winding speed should be the winder are increased by the controller to reduce the level of the yarn storage.
  • the controller should be designed to reduce the winding speed to increase the level of yarn storage (provided there is no yarn break that could be detected, for example, by the yarn guard).
  • the sensor system comprises more than two, preferably spaced-apart, sensors. Also, only one sensor could be present to monitor the fill level of the yarn store based on the presence of a yarn at one or more predetermined positions within the yarn store.

  • the sensor or sensors may be designed as capacitive sensors, which are also suitable for detecting the presence of a yarn at one or more predetermined positions within the yarn memory.
  • the spinning station is in operative connection with a controller, with the aid of which the winding speed of the winding device can be influenced as a function of the fill level information of the yarn store provided by the sensor system.
  • This ensures that the fill level of the yarn store always corresponds to a value within defined limits.
  • the yarn storage can both deliver a certain length of yarn as well as record and thus cause the desired buffer effect during yarn production.
  • fluctuations in the winding speed and / or the delivery speed of the spinning unit can be absorbed in a simple manner, without resulting in yarn breakage.
  • the spinning station comprises a yarn brake arranged downstream of the yarn store in the transport direction.
  • the yarn brake may, for example, comprise a spring arrangement with the aid of which a certain clamping force can be exerted on the yarn.
  • the clamping force in particular by means of a controller, should be controllable (at least it should be possible to switch on the yarn brake with the aid of the control only when needed in order to activate or deactivate the braking effect exerted on the yarn).
  • the spinning station comprises a yarn separation unit, which is preferably placed in the region of the yarn storage.
  • the yarn separation unit may, for example, comprise a blade unit with the aid of which a specific yarn section can be separated from the remaining yarn after the detection of a yarn breakage.

  • the yarn store has at least one injection nozzle, with the aid of which an air flow can be generated within the yarn store, which is directed in a direction away from a yarn inlet opening of the yarn store. Due to the Venturi effect, the air flow enhances the suction effect of the yarn store.
  • the injection nozzle (s) is or are in operative connection with a controller which is designed to then supply the injection nozzle (s) with compressed air, if the yarn is partly released from the yarn after a yarn break Spool is to be unwound (this is particularly useful to ensure that not only the detected yarn defect, but also a correspondingly long, the yarn defect preceding yarn section can be separated from the remaining yarn, which may also already deviate from the specified quality standard).
  • the spinning station preferably in the region of the yarn store, has a yarn end preparator for processing a yarn end before a subsequent piecing operation.
  • the yarn end preparation may be part of the yarn storage or placed in its immediate vicinity and connected to it via corresponding support sections.
