Definitions

  • the present invention relates to a method for interrupting the production of yarn on a spinning machine, wherein the spinning machine has at least one spinning station with an input for a fiber material and an output for the yarn made of the fiber material, and wherein the spinning machine a delivery device for the supply of the fiber material in the spinning station, a take-off device for the withdrawal of the yarn from the spinning station, a winding device for winding the produced yarn and a yarn monitoring unit for monitoring at least one yarn parameter (eg in the form of the yarn thickness or other parameter representative of the quality of the yarn), wherein the yarn production upon detection of a defined deviation of the monitored Garnparameters is interrupted by a target value in a bobbin change on the winding device and / or before switching off the spinning machine.
  • the spinning machine has at least one spinning station with an input for a fiber material and an output for the yarn made of the fiber material
  • the spinning machine a delivery device for the supply of the fiber material in the spinning station, a take-off device for the withdrawal of the yarn from the spinning station
  • a spinning machine for producing a yarn, wherein the spinning machine has at least one spinning station with an inlet for a fiber material and an outlet for the yarn made of the fiber material, and wherein the spinning machine has a delivery device for feeding the fiber material into the spinning station, a withdrawal device for the withdrawal of the yarn from the spinning station, a winding device for winding the yarn produced and a yarn monitoring unit for monitoring at least one yarn parameter.
  • the object of the present invention is therefore to propose a method and a spinning machine which make it possible to accelerate the finding of the yarn end after a controlled interruption of the yarn production.
  • the method is characterized in that, to interrupt the yarn production, the conveying speeds of the delivery device, the removal device and the winding device are gradually reduced to their standstill, wherein the reduction takes place such that the end of the yarn produced after completion of the reduction between the Output of the spinning station and the winding device is located.
  • the operated spinning machine is preferably an air spinning or rotor spinning machine.
  • Both types of spinning machine are characterized by the fact that certain conditions with regard to the conveying speeds of the delivery device and the withdrawal device must be observed for the desired yarn production. So, these have to be for the production of a high quality Exceed certain limits in order to allow the desired spin distribution of the fiber material inside the spinning chamber.
  • the mentioned conveying speeds gradually, ie preferably within a few seconds, throttled, so finally the point is reached at which no more yarn production takes place because either too little fiber material transported into the spinning chamber or the yarn in relation to the supply of the fiber material too fast the spinning chamber is withdrawn. At this time, finally, a yarn end is formed, which moves in the direction of the winding device in accordance with the remaining conveying speed of the drawing-off device.
  • the conveyor speeds are finally reduced to zero in the context of the interruption of the yarn production in such a way that the yarn end between the output of the spinning station and the winding device is after the standstill of the individual conveyors. It is therefore intended to stop the yarn formation within the spinning chamber by gradual and thus not abrupt throttling of the individual conveying speeds. The corresponding yarn end is thus created by appropriate adaptation of the individual conveyor speeds.
  • the yarn production is stopped, so that the yarn separates from the subsequent fiber material.
  • the winding device can be specifically slowed down, so that a defined final state is formed, in which the end of the yarn at the position described - and thus not on the surface a corresponding coil of the winding device - is located.
  • the end of the yarn can finally be grasped at the said position by the operator or a robot unit and prepared for further piecing or moved to the corresponding point provided for piecing without previously a yarn end seek on a coil surface would be needed.
  • the delivery device are formed by a pair of delivery rollers and / or the withdrawal device by a take-off roller pair.
  • Such rollers allow precise control of the respective conveyor speeds by adjusting their speeds. The speeds can thus be reduced within the scope of the inventive method within a predetermined period of time, which is usually between one and several seconds, without causing a tearing of the yarn.
  • the end of the yarn produced is located after the completion of the reduction of the conveying speeds between the output of the spinning station and the take-off device.
  • the yarn end is in this case in a position that is easily accessible from the outside.
  • it is reliably prevented that the yarn reaches the area of the winding device.
  • a reliable gripping the yarn end by a gripping device for.
  • a robot allows, with the yarn end always comes to a pre-defined position to a stop, which is preferably stored in the control of the gripping device.
  • the delivery speeds are first reduced to defined amounts, where no yarn production is possible within the spinning station and that then the trigger device and preferably also the winding device continue to operate at the respective conveying speeds until the end of the produced Garns is located at a defined position between the output of the spinning station and the winding device.
  • the conveying speed is less than during the actual yarn production, so that the final movement of the yarn end from the spinning position into the area between its outlet and the winding device can be reliably controlled.
  • the conveying speeds are reduced continuously, preferably linearly. This avoids abrupt changes in speed and possible tearing of the yarn.
  • a linear speed reduction is of course also any deviating reduction conceivable.
  • it is advantageous to simultaneously reduce the delivery speeds of the delivery device and the withdrawal device or to stop said devices at the same time it has proven to be advantageous to reduce the respective delivery rates over time.
  • the drives of the delivery device and the withdrawal device can be controlled separately.
  • a yarn storage device has, for example, a hollow cylinder which is connected to a vacuum source in such a way that a vacuum can be generated in the hollow cylinder as required (for example by targeted delivery of the vacuum source).
  • the trigger device is stopped later than the winding device, so after the stop of the winding device withdrawn from the place of meaning yarn sucked into the hollow cylinder and thus at a defined position being held.
  • the operator or a corresponding service robot can grasp the yarn section located between the yarn store and the winder and begin piecing.
  • the yarn section located in the yarn store can in this case be pulled out of the yarn store with the remaining yarn.
  • the yarn is fixed after completion of the reduction of the conveying speeds by means of the trigger device. If these are suitable take-off rolls, then the yarn can be reliably clamped between the respective corresponding rolls. For this purpose, it is only necessary to stop the take-off rollers before passing through the yarn end. If the yarn end is finally grasped manually or automatically for piecing, the clamping is released and the yarn end is released again, whereby before the release a (renewed) defined conveying of the yarn end can take place through the draw-off rolls in or against the spinning direction.
  • the robot comprises corresponding yarn handling devices, such as a gripping device and / or corresponding suction or blowing devices, in order to guide the yarn end through the exit of the spinning station counter to the actual spinning direction into the region in which the actual piecing process is to take place, which also takes place with the aid of of the robot can be performed.
  • yarn handling devices such as a gripping device and / or corresponding suction or blowing devices
  • the yarn is detected by the robot before piecing between the output of the spinning station and the winding device. This allows an early fixation of the yarn end by the robot, so that the entire yarn return or the subsequent piecing process can be controlled. While the yarn end can be threaded from behind through the spinning station, it is also conceivable to make the spinning position such that a part is removable or open to insert the yarn in the spinning position can.
  • the piecing process takes place outside the spinning station, in particular between the delivery device and a roller pair of a drafting system.
  • the fiber material to be spun is usually fixed after standstill of the delivery device, for example by means of corresponding delivery rollers, or in the case of an air-spinning machine, a pair of rollers of an upstream drafting system. Since contact between the fiber material and the returned yarn end must be produced during piecing, it is therefore advisable to carry out the piecing process in this area.
  • the fixation of the yarn is completed before or while it is detected by the robot. This avoids tearing of the yarn at this stage. Alternatively, however, it is also not excluded that the fixation is terminated only after the robot has grasped the yarn. Such a temporal sequence would be conceivable, for example, when using a (vacuum) thread store. If the fixation by the corresponding take-off rolls, so it would still be conceivable in this context, one of the rollers of the robot during or shortly after the gripping of the yarn to lift off the backing roll. Alternatively, it would also be possible to drive the take-off rolls back after gripping the yarn end, so that the yarn is actively conveyed in the direction of the spinning position. Of course, if necessary, the take-off rolls can also be driven in the opposite direction, so that the end of the yarn produced can be moved to the intended position in any case.
  • the position of the end of the yarn produced is determined by means of a sensor.
  • a sensor can be positioned, for example, in the region of the exit of the spinning station or between the withdrawal device and the winding device.
  • the detection of the end of the thread can finally be done using light beams or mechanically.
  • the sensor in addition to or alternatively to the determination of said position, other parameters, such as the general presence of a yarn at predetermined sections of the spinning machine, can determine.
  • the reduction of the conveying speeds depends on physical and / or chemical properties of the fiber material (type of fiber material, strength, staple length, etc.) and / or characteristics of the spinning machine, in order to be able to optimally respond to the respective conditions.
  • the parameters of the spinning machine can include individual speeds, delivery speeds or corresponding parameters of the drafting system used. Likewise, moisture and / or temperature values can be taken into account at defined points of the spinning machine or even the premises surrounding the spinning machine.
  • the spinning machine according to the invention is characterized in that it has a control and / or regulating unit which is designed to operate the spinning machine in accordance with one or more aspects of the preceding description.
  • yarn handling devices would be used which could grasp the yarn end possibly wound on the spool of the corresponding winding device and feed it to the subsequent piecing process.
  • the yarn handling devices can be assigned to be part of a service robot patrolling between the respective spinning stations or also individually assigned to each spinning station.
  • the yarn does not necessarily have to be grasped at its end before the piecing process. It is therefore also conceivable, for example, to grasp the yarn between its end section (preferably fixed with the help of the draw-off rollers) and the bobbin of the winding device.
  • the measured values thereof can serve as the basis for the further process sequence. For example, initiating a piecing process only makes sense if a successful interruption of the yarn production has occurred or the end of the yarn has been fixed accordingly.
  • a further possibility of optimizing the method according to the invention or the spinning machine described would be achieved by designing the method for interrupting yarn production "self-learning".
  • the individual parameters (amount and beginning of the reduction of the respective conveying speeds, time of stopping the delivery device, the withdrawal device and / or the winding device, characteristics of the piecing process, etc.) depend on the data supplied by the corresponding sensors be adjusted in a preferably continuous and carried out by the control and or regulating device of the spinning machine process.
  • FIG. 1 is a schematic view of a section of an air-spinning machine according to the invention shown.
  • the air-spinning machine comprises a drafting system 16, which is supplied with a fiber material 3, for example in the form of a relined conveyor belt.

  • the spinning machine shown comprises a take-off device 7 formed by a take-off roller pair 12 and a winding device 8 connected downstream of the take-off roller pair 12 for the yarn 5 withdrawn from the spinning station 1 through the exit 4.
  • the spinning machine is equipped with a yarn monitoring unit 9 which monitors previously defined parameters of the yarn 5 (eg yarn thickness, yarn tenacity or other parameters representative of the quality of the yarn 5).
  • the yarn monitoring unit 9 preferably operates without contact.
  • the device according to the invention need not necessarily have a drafting device 16, as shown in FIG FIG. 1 is shown. Also, the pair of take-off rollers 12 is not mandatory.
  • the spinning machine according to the invention may also be designed as a rotor spinning machine, wherein the spinning station 1 in this case has a rotor instead of the spindle 17 shown, through which the yarn 5 produced at the tip of the spindle 17 is withdrawn from the spinning station 1.

  • the reduction need not be simultaneous or continuous. In any case, however, the respective conveying speeds should be throttled so that the spinning process can be maintained as long as possible. Tearing of the yarn 5, as common in the art, can be eliminated in this way. Rather, it is the goal of reducing the conveyor speeds that the stable spinning process collapses by falling below defined conveyor speeds and thus at a certain time no yarn 5 is more produced from the fiber material 3. At this point in time, it finally comes to the desired interruption of yarn production, in which the yarn 5 dissolves from the fiber material 3 without separate force. This can be achieved, for example, by reducing the conveying speed of the delivery device 6 to such an extent that it no longer supplies a sufficient quantity of fiber material 3 in order to form a yarn 5 therefrom. It is also possible to slow down the conveying speed of the take-off roller pair 12 slower (or even faster, if required) than the conveying speed of the delivery roller pair 11 and / or the winding device 8.
