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.
  • Object of the present invention is therefore to accelerate the piecing after a controlled interruption of yarn production.
  • the method is characterized in that, to interrupt the yarn production, the conveying speeds of the delivery device, the take-off 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 within the Spinning station 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.
  • 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 yarn end can now be prepared for further piecing or provided for the corresponding piecing Be moved without previously a yarn end search on a coil surface would be necessary.
  • the delivery device is formed by a delivery roller pair and / or the removal device by a pair of take-off rollers.
  • 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 spinning station has an air vortex chamber and a hollow spinneret projecting into the air vortex chamber, through which the produced yarn is withdrawn from the air vortex chamber in the direction of the exit of the spinning station during yarn production, and the conveying speeds are reduced such that the end of the manufactured yarn is inside the spinneret after completion of the reduction.
  • the yarn end need not be threaded in this case contrary to the actual spinning direction in the spinneret, so that a large part of the necessary Fadenhandhabungs- and thread guide work, which are necessary in the prior art before the piecing, omitted.
  • the yarn end now only has to be moved (for example, pushed or sucked) counter to the spinning direction so that the yarn end, possibly prepared for piecing in an intermediate step, can be brought into contact with the subsequent fiber material.
  • the actual piecing process ie the connection of fiber material and yarn end, can finally be done in a conventional manner.
  • 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.
  • the drives of the delivery device and the withdrawal device can be controlled separately.
  • the withdrawal device comes to a standstill in time after the delivery device.
  • a defined distance is created between the yarn end and the previously stopped fiber material, whereby in the case of an air-spinning machine it can be prevented that fiber material enters the spinneret together with the yarn end.
  • 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 comes to a standstill after the winding device. This makes it possible, for example, that the portion of the yarn which is generated during the reduction of the conveying speed, is not wound on the bobbin of the winding device. Finally, this section should be removed before re-spinning Finally, a corresponding unwinding process from the spool is eliminated. Rather, it would be conceivable, for example, to temporarily store the mentioned section within a separate yarn store and to remove it before the actual piecing process.
  • the yarn finally runs without deflections from the spinning station to the winding device.
  • the yarn end is outside the spinning station or the twisting agent of the same (for example outside the spinning nozzle of an air spinning machine), the piecing process can finally be started.
  • the yarn is fixed after completion of the reduction of the conveying speeds by means of the take-off 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 rolls as soon as the end of the yarn is inside the spinning station. 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 end of the yarn produced moves after the interruption of the yarn production in an area between the input of the spinning station and the delivery device or in a region between the delivery device and a pair of rollers of a drafting and then during a piecing with the fiber material is connected.
  • 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 against the actual spinning direction into the region in which the actual piecing process is to take place, which can likewise be carried out with the aid of the robot ,
  • yarn handling devices such as a gripping device and / or corresponding suction or blowing devices
  • 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 yarn section produced during the reduction of the conveying speeds is removed before the piecing process.
  • the yarn that is produced during the reduction of the individual conveying speeds have a reduced yarn quality. If the interruption of the yarn production is due to the detection of a yarn defect, it should also be ensured that the portion containing the yarn defect detected by the monitoring unit is also removed. In this case, therefore, the length of the yarn section to be removed corresponds at least to the length of the yarn which, after the interruption of the yarn production, is between the yarn end produced and the yarn defect.
  • the parameters of the spinning machine can include individual speeds, delivery speeds or corresponding parameters of the drafting system used.
  • humidity and / or temperature values can be defined Spaces of the spinning machine or even the spinning machine surrounding premises are taken into account.
  • the holding or fixing of the yarn end has the advantage that this is in the desired position until the next process step of the piecing process (which could also be monitored with a sensor if necessary).
  • 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 according to one or more aspects of the preceding description, wherein the interruption of the yarn production at individual or even at all spinning stations the spinning machine can be done in the manner according to the invention.
  • yarn handling devices which can grip the yarn end possibly wound on the bobbin 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 individual Equip spinning stations with appropriate Garnhandhabungs droveen and yet use one or more service robots, thereby achieving a certain division of labor.
  • a further possibility of optimizing the method according to the invention or the spinning machine described would be obtained 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 shows a schematic view of a section of an air-jet spinning machine according to the invention.
  • 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 air spinning machine shown in principle comprises a spaced apart from the drafting 16 spinning station 1 with an inlet 2 for the fiber material 3 and an internal air vortex chamber fourteenth
  • the fiber material 3 is introduced into the spinning station 1 by means of a delivery device 6 designed as a delivery roller pair 11, which in turn can be part of the drafting system 16. Finally, within the air vortex chamber 14, the fiber material 3 or at least a part of the fibers of the fiber material 3 is provided with a rotation in order to produce the desired yarn 5.
  • the rotation is produced by a targeted air flow in the region of a spindle 17, wherein the air flow is generated by not shown, tangentially opening into the air vortex chamber 14 nozzles.
  • 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.
  • FIG. 1 the course of the fiber material 3 and in the spindle 17 produced yarns 5 during the actual spinning process.
  • the conveying speeds of the delivery device 6, the discharge device 7 and the winding device 8 become gradually reduced. Likewise, the reduction can be done before the spinning machine is turned off.
  • 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 without separate force from the fiber material 3. 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.
  • the yarn storage 13 (eg, in the form of a tube connected to a vacuum source) may be held to prevent the yarn 5 produced during the reduction of the conveying speeds from being wound onto the winding device 8 (the yarn store 13 is of course not true to scale, but only shown schematically).
  • the end 10 of the yarn 5 is finally with the help of a service robot, a spinning mill own yarn handling device or manually against the actual spinning direction in the air vortex chamber 14, between the input 2 of the spinning station 1 and the delivery device 6 or between the delivery device 6 and an adjacent Roller pair 15 of the drafting 16 shifted. There it can be brought into contact with the fiber material 3 and reintroduced into the spinning station 1. The spinning process finally starts again.
  • the yarn 5 after the interruption of the yarn production, as well as in the FIGS. 1 and 2 shown, additionally or alternatively to the yarn storage 13 by means of the pair of take-off rollers 12 are fixed.
  • This can through Direction reversal also serve to move the end 10 of the yarn 5 before piecing against the spinning direction.
  • a cutting and / or disposal device 19 may be arranged between the drafting system 16 and the spinning station 1 or even at the spinning station 1 itself, with the aid of which the end 10 of the yarn 5 can be prepared accordingly before piecing.
  • a portion of the yarn 5 is usually cut off and disposed of, for example by means of negative pressure on the cutting and / or disposal device 19, which also acts as a suction device in this case.
