Definitions
- the present invention relates to a method for operating a textile machine with a plurality of juxtaposed workstations, wherein the workstations as working members have at least one spinning station for producing the thread and / or a winding device for winding the thread onto a spool. Furthermore, the workstations own work handling organs for re-spinning the thread or for connecting two thread ends. In the method, when the production is interrupted, a coil-side thread end is provided in a defined receiving position at the workstation.
- the coil-side thread end is picked up by working organs of the job, in particular the workstation's own handling organs from the receiving position, cut to length, prepared for piecing and spun or connected to the other thread end.
- the invention relates to a textile machine with a plurality of longitudinally of the textile machine juxtaposed jobs, which have as working members in each case at least one spinning station for producing a yarn and / or a winding device for winding the yarn on a spool.
- the jobs on several workstations own handling organs for re-spinning the thread or for connecting two thread ends.
- a coil-side thread end can be taken, cut to length, prepared for piecing and spun or connected to the other end of the thread.
- the EP 1 283 288 B1 Therefore proposes another approach to the maintenance of jobs, in which all handling organs for re-spinning a thread and possibly other maintenance organs are located directly at each work site.
- the work stations of the spinning machine have controllable individual drives in order to be able to drive the working members of the spinning station in a suitable manner in accordance with the requirements both during piecing and during regular spinning operation.
- every job is capable after an interruption the production to independently re-spin the thread.
- the problem of waiting times and the associated loss of production can be avoided thereby.
- such a machine equipped with single-user automation is comparatively expensive.
- the design effort is high due to the large number of components to be arranged per workstation.
- the object of the present invention is to propose a method and a textile machine, by means of which even in the event of unforeseen interruptions of production, the thread end can be quickly fed to the piecing process.
- the workstations In a method for operating a textile machine with a plurality of workstations arranged side by side in the longitudinal direction of the textile machine, the workstations have at least one spinning station with a spinning device for producing the thread and / or a winding device for winding the thread onto a bobbin. Furthermore the workplaces have their own handling organs for re-spinning the thread or for connecting the thread ends. When production is interrupted, a coil-side thread end is provided in a defined receiving position at the workstation. For re-spinning a thread, the coil-side end of the thread is picked up by the working organs of the workstation, in particular the workstation's own handling organs, cut to length, cut to length, prepared for re-spinning and spun.
- a textile machine has a plurality of workstations arranged side by side in the longitudinal direction of the textile machine.
- the jobs contain as working organs in each case at least one spinning station with a spinning device for producing a thread and / or a winding device for winding the thread on a spool, and in both cases several workstation own handling organs for re-spinning the thread.
- a coil-side thread end can be picked up from a defined picking position, cut to length, prepared for piecing back and spun or connected to the second thread end.
- the textile machine has at least one in the range of several jobs of the textile machine movable yarn detection device, which is a Vietnamesebeetzyerbare Having suction nozzle for finding a accumulated on the spool thread end. Furthermore, a transfer member is provided for transferring the thread end of the suction nozzle in the receiving position at the working place, from which the thread end by a working organ, in particular a working-own handling member, is receivable.
- the workstations With the method described or the textile machine described, it is possible to provide the workstations largely self-sufficient, so that they can perform the piecing process or connection process, eg. Splicing process, independently and without waiting in most cases. Since at an interruption of production, the thread end is always provided in the defined receiving position, from which it can be taken over directly by work organs of the workplace, can be dispensed with a workstation own thread search device. This results in a significant cost advantage over a complete single-user automation and a constructive simplification of the individual jobs, since there is no space-intensive thread search device must be accommodated.
- the movable yarn-finding device which can be fed to several workstations and to feed it to the reattachment. Since the movable between multiple work stations and forth thread search device is reduced to only one or two functions, namely the thread search and possibly the transfer to the spinning station, compared to a conventional maintenance facility as well as compared to a complete single-user automation significant cost advantages. In addition, even if at several jobs at the same time a thread break must be repaired, the waiting times are on the thread-seeking device can be significantly reduced because they only need to visit the thread and handed over to the spinning unit. The next job can thus be operated much faster.
- the thread end is spent by means of a transfer member of the thread-seeking device in the receiving position at the workplace.
- the at least one transfer element is correspondingly arranged on the thread search device.
- the thread search device includes in this case as working organs only a suction nozzle, a transfer member and possibly also a thread cutting device.
- the transfer member may for example be designed as a pivoting arm, movable hook, linearly movable or backdrop-guided feeder or as a pneumatic transfer member.
- the thread end can thus be passed through the thread-seeking device directly to the job or the work organs of the job. In principle, however, it is also conceivable to arrange a transfer member at the work station, which then takes over the thread end of the suction nozzle and transferred to the receiving position.
- the receiving position from which the thread end is received by a working organ, in particular a work-own handling element, preferably in the yarn path between an output of the spinning station and the winding device, in particular between the output of the spinning station and a take-off device of the spinning station.
- a working organ in particular a work-own handling element
- This area of the job is easily accessible, so that the thread end can be transferred by the thread-seeking device or the transfer member well into this receiving position.
- the workstation is shut down in a controlled manner or can be stopped in a controlled manner.
- the work organs of the workstation can be controlled and coordinated with each other to decelerate to a standstill, so that the thread end eventually stops in the defined receiving position and does not run on the coil. Any waiting times on the thread search device are hereby further shortened, since these only in the case unplanned interruptions of production, in which the thread end runs onto the spool is needed.
- the thread-seeking device spends the thread end when it is being brought into the receiving position into the area of action of a pneumatic working member, in particular a pneumatic handling member of the workstation.
- a pneumatic handling member is usually provided at the workstations anyway to be able to fix the thread end during piecing or to form a thread reserve.
- the thread end directly by a pneumatic working member of the workplace, in a spinning machine, for example, the spinning device is recorded.
- the thread end can be received, for example, through the take-off nozzle of the rotor spinning device or, in the case of an air-spinning machine, through the air-spinning nozzle. In any case, the thread end can thereby be transferred very quickly through the thread-seeking device to the job, so that waiting times are further reduced.
- the thread-seeking device at the same time inserted the thread end when moving into the receiving position in the take-off device of the job and / or in a yarn guide of the winding device and / or in a yarn monitoring device.
- the thread end is thus spent directly through the thread-seeking device in a position in the threadline, in which it would be even after a controlled shutdown of the job. Additional handling facilities at the workplace are therefore not required.
- the thread end is passed through the thread-seeking device only to a pneumatic handling element and from there by further work-own handling organs in which the trigger device and / or in the thread guide and / or in the yarn monitoring device is inserted.
- the thread-seeking device is movable in the longitudinal direction of the textile machine along a plurality of workstations arranged next to one another. It is again advantageous if the thread-seeking device can be moved by means of its own traction drive. However, it is also conceivable to arrange a drive for the thread-seeking device on the textile machine and to connect the thread-seeking device to the drive by means of a coupling element, for example a belt drive. Such a movable thread search device can be made particularly space-saving, so that the arrangement of the working organs of the job is thereby structurally easier.
- the textile machine is provided as a double-sided textile machine
- such a thread search device which can be moved in the longitudinal direction of the textile machine can be designed in a simple and space-saving manner if it can be moved centrally between two longitudinal sides of the textile machine.
- the thread-seeking device can contain separate working members for each of the two longitudinal sides, ie in each case a suction nozzle and, if appropriate, in each case a transfer element.
- a common suction nozzle can be provided for both longitudinal sides of the textile machine, which can be delivered to the two longitudinal sides or their workstations alternately.
- the common suction nozzle and, if appropriate, a common transfer element can, for example, be arranged so as to be pivotable or foldable on both sides along a movable frame.
- the thread-seeking device is arranged to be movable back and forth between at least two work stations of the textile machine on the textile machine.
- a thread search device each side between two in the longitudinal direction be located at work and pivot between these back and forth.
- the thread-seeking device can also be foldable and / or if necessary also be telescoped so that, for example, four workstations lying next to one another can be operated.
- the workstation's own handling devices further comprise at least one thread separation unit for cutting the thread end, a thread preparation unit for preparing the cut thread end and a return unit for returning the prepared thread end into the spinning station and / or to a connection point.
- the connection point is in the case of a winder in the region of a splicer. In the case of a spinning machine, this may also be located outside the spinning station.
- the return unit can be executed both by an additional device, such as an auxiliary roller pair, or be formed by the regular deduction device.
- FIG. 1 shows a spinning machine 1 in a first embodiment as an air spinning machine in a schematic overview.
- the spinning machine 1 includes in a conventional manner a plurality of juxtaposed jobs 2, each of which a drafting system 22 with a pair of delivery rollers 27, a spinning unit 3 with a spinning device 28, here in the form of an air spinneret, a take-off device 9 and a winding device 4 with a traversing device, not shown, and have a yarn guide 11.
- the drafting unit 22 is a fiber material F 'is supplied, which is stretched in the drafting system 22 and fed via the feed rollers 27 of the spinning station 3 with the air-jet nozzle.
- the yarn F produced there is withdrawn from the spinning station 3 by means of a take-off device 9 and fed to the present illustration via a yarn monitoring device 15 and a paraffining device 26 of the winding device 4, where it is wound onto a bobbin 5.
- a number of handling elements 10, 16, 17, 18 is provided at the workstation 2, by means of which, after an interruption of production, here the spinning process, a coil-side yarn end 6 can be spun again.
- the thread end 6 is cut to length by a thread separation unit 16, prepared for piecing by a thread preparation unit 17 and returned to a connection point 19 outside the spinning station 3 by a return unit 18 into the spinning station or through the spinning station 3.
- the return unit 18 is formed by the withdrawal device 9 of the work station, which is driven to return the thread end 6 opposite to the regular withdrawal direction.
- the return unit 18 can also be designed as a separate unit, for example as an auxiliary roller pair.
- a pneumatic handling member 10 is arranged at the workstation 2 to temporarily fix the yarn end 6.
- this is not absolutely necessary, depending on the arrangement of the individual modules and handling elements 16, 17, 18 at the workstation 2, it is also possible to fix the thread end 6 by means of the take-off device 9.
- a pneumatic handling member 10 for fixing the thread end 6 or to form a thread reserve when re-spinning also be provided elsewhere in the yarn path at the job 2 or there may be more than one pneumatic handling elements 10 available.
- the present illustration now shows a situation at the workplace 2 after a targeted interruption of the spinning process.
- a controlled shutdown can be done with every predictable spinning stop, so for example to eliminate a yarn defect, bobbin change or shutdown of the job 2 or the spinning machine.
- the conveying speeds of the individual working members 27, 9, 4 of the workstation 2, here at least the delivery rollers 27, the take-off device 9 and the winding device 4 gradually and coordinated with each other reduced to a standstill.
- the drives of the individual work organs 27, 9, 4 are for this purpose equipped with individually controllable drives (not shown), which are controllable by a control device (not shown) of the job 2 or the spinning machine 1 accordingly.
- the thread end 6 thereby does not run on the bobbin, but is in a defined receiving position A between an output 8 of the spinning station 3 and the winding device 4. From there it can easily by the handling members 10, 16, 17, 18 of the job. 2 be recorded and be re-spun. Since the coil-side yarn end 6 remains essentially in its regular yarn path, it must not be after piecing also to the working organs of the job 2, in particular the trigger device 9, the yarn monitoring device 15 and the yarn guide 11 are inserted.
- the receiving position A is located in the present case between the output 8 of the spinning station 3 and the take-off device 9.
- the yarn-seeking device according to the present invention in particular a movable yarn-seeking device for a variety of jobs, can be used particularly advantageously on a spinning machine, the jobs are controlled shutdown.
- the thread-seeking device is only needed in the case of unplanned interruptions of the spinning process, so that only a few or even only one thread-seeking device per spinning machine is to be provided.
- a movable between several jobs thread search device is also advantageous in conventional jobs without the possibility of controlled shutdown.
- FIG. 2 shows a first embodiment of a spinning machine 1, which as well as the spinning machine 1 of FIG. 1 is designed as an air-spinning machine.
- the spinning machine of the FIG. 2 In the structure of their jobs 2 corresponds essentially to that in the FIG. 1 described so that they are no longer described.

- the movable yarn search device 7 is provided.
- the yarn-searching device 7 can position itself at the relevant workstation 2 and, by means of the movable suction nozzle 12, approach the yarn end 6 on the spool 5.
- the coil 5 is for this purpose driven by a drive, not shown, at the workstation 2 counter to their regular direction of rotation, so that the yarn end 6 can be sucked into the suction nozzle 12.
- the yarn end 6 is received by the transfer member 13 of the suction nozzle 12 and passed to the pneumatic handling member 10 of the job 2 in the form of a thread loop.
- the thread end 6 is now in the defined recording position A.
- the yarn end 6 When moving the yarn end 6 into the receiving position A, the yarn end 6 is at the same time in the working organs of the spinning station, in this case at least the yarn monitoring device 15, and the trigger 9 inserted, so that the yarn end 6 as before FIG. 1 described by the workstation's own handling devices 10, 16, 17, 18 can be spun.
- the thread end 6 can also be inserted at the same time in the yarn guide 11.
- the thread F can initially be stored outside of the thread guide 11 and be inserted into this again after successful piecing.
- FIG. 2 a situation is shown in which the thread end has already been found on the bobbin 5 and inserted by the transfer member 13 in the take-off device 9 and the yarn monitoring unit 15 and passed in the form of the thread loop to the pneumatic handling member 10.
- the thread-seeking device 7 in this case with respect to the piecing process must perform only the two functions of thread search and - transfer, while the handling elements for piecing 10, 16, 17, 18 are located at the workplace 2, the thread-seeking device 7 can be structurally very simple and manufactured inexpensively. According to another embodiment, the thread-seeking device can additionally perform a cutting function, the thread-seeking device 7, however, can still be performed very easily and inexpensively. In addition, the thread-seeking device 7 immediately after the transfer of the thread end 6, the next job 2, where a thread break occurred, visit. In addition, since the thread-seeking device 7 only in the case of an unforeseen, relatively rare thread breakage, However, it is not required for plannable interruptions of the spinning operation, waiting times can be almost completely avoided at the jobs 2 with corresponding production losses.
- the suction nozzle 12 is designed to be pivotable and has a drive 14 for this purpose.
- the suction nozzle 12 could also be performed linearly movable or be deliverable to the coil 5 in any other way. It is also not essential to provide a separate transfer member 13.

- the conveying speeds of the working organs of the workstation 2, in particular the feed device 24, the opening device 25, the take-off device 9 and the winding device 4 can also be defined and reduced to a standstill, so that the thread end 6 does not run onto the spool 5, but is located at a defined receiving position A.
- this is not necessary.
- the thread search device 7 corresponds in its structure and its function of the thread search device 7 of FIG. 2 , so on the description for FIG. 2 is referenced.
- the described yarn-searching device 7 can be used in various textile machines such as winders, air-jet spinning machines or rotor spinning machines. Since the thread search device 7 respectively only briefly to the thread search and handover at a workstation 2 is in use, while all the time-consuming work of the piecing process, in particular the cutting and preparation of the thread end 6, are performed directly by the workstation 2, there is a considerable time advantage over a conventional maintenance device.
- the thread-seeking device 7 can immediately visit the next job after thread transfer to the receiving position, so that waiting times can be avoided with corresponding production losses.
- the movable yarn-searching device 7 can operate a plurality of jobs 2 in succession in a short time, it is not necessary to arrange a cost-intensive yarn-searching device with a high space requirement at each of the jobs 2. It is furthermore advantageous that the number of yarn-searching devices 7 on a textile machine can be adapted without problems to different machine lengths or different numbers of workstations 2 or also the expected yarn breakage rate.
- the proposed yarn-searching device 7 can moreover be produced very cost-effectively, since, in addition to its basic components such as the frame 20, the chassis 21 and devices for power supply and control, as working elements, it has only one suction nozzle 12 and one or more transfer organs 13.

So ist es bei vielen Textilmaschinen üblich, diese mit entlang der Arbeitsstellen verfahrbaren Wartungseinrichtungen auszustatten, die an den Spinnstellen sämtliche Wartungsvorgänge wie die Behebung von Fadenbrüchen, Spulenwechsel, Rotorreinigung, Anspinnen auf Leerhülse und dgl. durchführen. Die Wartungseinrichtungen weisen hierzu einen sehr komplexen Aufbau mit einer Vielzahl verschiedener Handlingsorgane auf. Eine derartige Spinnmaschine mit einer verfahrbaren Wartungseinrichtung ist beispielsweise in der
Um die Wartezeiten auf eine verfahrbare Wartungseinrichtung zu verringern, ist es auch bekannt geworden, auf jeder Seite einer Spinnmaschine mehrere Wartungseinrichtungen vorzusehen. Die

Aufgabe der vorliegenden Erfindung ist es, ein Verfahren und eine Textilmaschine vorzuschlagen, mittels welchen auch bei unvorhergesehenen Unterbrechungen der Produktion das Fadenende schnell dem Anspinnvorgang zugeführt werden kann.The object of the present invention is to propose a method and a textile machine, by means of which even in the event of unforeseen interruptions of production, the thread end can be quickly fed to the piecing process.
Die Aufgabe wird gelöst mit den Merkmalen der unabhängigen Ansprüche.The object is solved with the features of the independent claims.
Bei einem Verfahren zum Betreiben einer Textilmaschine mit einer Vielzahl von in Längsrichtung der Textilmaschine nebeneinander angeordneter Arbeitsstellen weisen die Arbeitsstellen als Arbeitsorgane wenigstens eine Spinnstelle mit einer Spinnvorrichtung zur Herstellung des Fadens und/oder eine Spulvorrichtung zum Aufwickeln des Fadens auf eine Spule auf. Außerdem weisen die Arbeitsstellen arbeitsstelleneigene Handlingsorgane zum Wiederanspinnen des Fadens oder zum Verbinden der Fadenenden auf. Bei einer Unterbrechung der Produktion wird ein spulenseitiges Fadenende in einer definierten Aufnahmeposition an der Arbeitsstelle bereitgestellt. Zum Wiederanspinnen eines Fadens wird das spulenseitige Fadenende durch die Arbeitsorgane der Arbeitsstelle, insbesondere die arbeitsstelleneigenen Handlingsorgane, aus der Aufnahmeposition aufgenommen, abgelängt, zum Wiederanspinnen vorbereitet und angesponnen.In a method for operating a textile machine with a plurality of workstations arranged side by side in the longitudinal direction of the textile machine, the workstations have at least one spinning station with a spinning device for producing the thread and / or a winding device for winding the thread onto a bobbin. Furthermore the workplaces have their own handling organs for re-spinning the thread or for connecting the thread ends. When production is interrupted, a coil-side thread end is provided in a defined receiving position at the workstation. For re-spinning a thread, the coil-side end of the thread is picked up by the working organs of the workstation, in particular the workstation's own handling organs, cut to length, cut to length, prepared for re-spinning and spun.
Für den Fall eines Auflaufens des Fadenendes auf die Spule ist nun vorgesehen, dass ein auf die Spule aufgelaufenes Fadenende mittels einer im Bereich mehrerer Arbeitsstellen der Textilmaschine bewegbaren Fadensucheinrichtung auf der Oberfläche der Spule aufgesucht wird und anschließend das Fadenende in die Aufnahmeposition an der Arbeitsstelle verbracht wird. In der Aufnahmeposition wird das Fadenende schließlich durch ein Arbeitsorgan der Arbeitsstelle, insbesondere ein arbeitsstelleneigenes Handlingsorgan, aufgenommen und dem Ansetzprozess zugeführt.In the event of a run-up of the thread end of the spool is now provided that a thread end accumulated on the spool is visited by means of a movable in the field of several jobs of the textile machine thread search device on the surface of the spool and then the thread end is moved to the receiving position at the workplace , In the receiving position, the thread end is finally picked up by a working organ of the workstation, in particular a working-own handling element, and fed to the piecing process.
Eine Textilmaschine weist eine Vielzahl von in Längsrichtung der Textilmaschine nebeneinander angeordneten Arbeitsstellen auf. Die Arbeitsstellen beinhalten als Arbeitsorgane jeweils wenigstens eine Spinnstelle mit einer Spinnvorrichtung zur Herstellung eines Fadens und/oder eine Spulvorrichtung zum Aufwickeln des Fadens auf eine Spule sowie in beiden Fällen mehrere arbeitsstelleneigene Handlingsorgane zum Wiederanspinnen des Fadens. Mittels der Arbeitsorgane, insbesondere der arbeitsstelleneigenen Handlingsorgane, kann ein spulenseitiges Fadenende aus einer definierten Aufnahmeposition aufgenommen, abgelängt, zum Wiederanspinnen vorbereitet und angesponnen werden bzw. mit dem zweiten Fadenende verbunden werden.A textile machine has a plurality of workstations arranged side by side in the longitudinal direction of the textile machine. The jobs contain as working organs in each case at least one spinning station with a spinning device for producing a thread and / or a winding device for winding the thread on a spool, and in both cases several workstation own handling organs for re-spinning the thread. By means of the work organs, in particular the workstation's own handling organs, a coil-side thread end can be picked up from a defined picking position, cut to length, prepared for piecing back and spun or connected to the second thread end.
Die Textilmaschine weist wenigstens eine im Bereich mehrerer Arbeitsstellen der Textilmaschine bewegbare Fadensucheinrichtung auf, welche eine unterdruckbeaufschlagbare Saugdüse zum Aufsuchen eines auf die Spule aufgelaufenen Fadenendes aufweist. Weiterhin ist ein Übergabeorgan vorgesehen zum Verbringen des Fadenendes von der Saugdüse in die Aufnahmeposition an der Arbeitsstelle, aus welcher das Fadenende durch ein Arbeitsorgan, insbesondere ein arbeitsstelleneigenes Handlingsorgan, aufnehmbar ist.The textile machine has at least one in the range of several jobs of the textile machine movable yarn detection device, which is a unterdruckbeaufschlagbare Having suction nozzle for finding a accumulated on the spool thread end. Furthermore, a transfer member is provided for transferring the thread end of the suction nozzle in the receiving position at the working place, from which the thread end by a working organ, in particular a working-own handling member, is receivable.
Mit dem beschriebenen Verfahren bzw. der beschriebenen Textilmaschine ist es möglich, die Arbeitsstellen weitgehend autark auszustatten, so dass diese in den meisten Fällen den Anspinnprozess oder Verbindungsprozess, bspw. Spleißvorgang, selbstständig und ohne Wartezeiten durchführen können. Da bei einer Unterbrechung der Produktion das Fadenende stets in der definierten Aufnahmeposition bereitgestellt wird, aus welcher es direkt durch Arbeitsorgane der Arbeitsstelle übernommen werden kann, kann auf eine arbeitsstelleneigene Fadensucheinrichtung verzichtet werden. Hierdurch ergibt sich ein erheblicher Kostenvorteil gegenüber einer vollständigen Einzelplatzautomation sowie eine konstruktive Vereinfachung der einzelnen Arbeitsstellen, da dort keine platzintensive Fadensucheinrichtung untergebracht werden muss. Dennoch ist es im Falle eines auf die Spule aufgelaufenen Fadenendes möglich, dieses mittels der bewegbaren, mehreren Arbeitsstellen zustellbaren Fadensucheinrichtung schnell aufzusuchen und dem Wiederanspinnen zuzuführen. Da die zwischen mehreren Arbeitsstellen hin-und her bewegbare Fadensucheinrichtung auf nur ein oder zwei Funktionen, nämlich die Fadensuche und ggf. die Übergabe an die Spinnstelle reduziert ist, ergeben sich gegenüber einer herkömmlichen Wartungseinrichtung ebenso wie gegenüber einer vollständigen Einzelplatzautomation erhebliche Kostenvorteile. Zudem können, selbst wenn an mehreren Arbeitsstellen gleichzeitig ein Fadenbruch behoben werden muss, die Wartezeiten auf die Fadensucheinrichtung erheblich reduziert werden, da diese lediglich den Faden aufsuchen und an die Spinnstelle übergeben muss. Die nächste Arbeitsstelle kann somit wesentlich schneller bedient werden.With the method described or the textile machine described, it is possible to provide the workstations largely self-sufficient, so that they can perform the piecing process or connection process, eg. Splicing process, independently and without waiting in most cases. Since at an interruption of production, the thread end is always provided in the defined receiving position, from which it can be taken over directly by work organs of the workplace, can be dispensed with a workstation own thread search device. This results in a significant cost advantage over a complete single-user automation and a constructive simplification of the individual jobs, since there is no space-intensive thread search device must be accommodated. Nevertheless, in the case of a thread end which has accumulated on the bobbin, it is possible to quickly locate it by means of the movable yarn-finding device which can be fed to several workstations and to feed it to the reattachment. Since the movable between multiple work stations and forth thread search device is reduced to only one or two functions, namely the thread search and possibly the transfer to the spinning station, compared to a conventional maintenance facility as well as compared to a complete single-user automation significant cost advantages. In addition, even if at several jobs at the same time a thread break must be repaired, the waiting times are on the thread-seeking device can be significantly reduced because they only need to visit the thread and handed over to the spinning unit. The next job can thus be operated much faster.
Nach einer besonders vorteilhaften Ausführung des Verfahrens wird das Fadenende mittels eines Übergabeorgans der Fadensucheinrichtung in die Aufnahmeposition an der Arbeitsstelle verbracht. Bei der Textilmaschine ist entsprechend das wenigstens eine Übergabeorgan an der Fadensucheinrichtung angeordnet. Die Fadensucheinrichtung beinhaltet in diesem Fall als Arbeitsorgane lediglich eine Saugdüse, ein Übergabeorgan sowie ggf. noch eine Fadenschneideinrichtung. Das Übergabeorgan kann beispielsweise als Schwenkarm, beweglicher Haken, linear beweglicher oder kulissengeführter Zubringerarm oder auch als pneumatisches Übergabeorgan ausgeführt sein. Das Fadenende kann somit durch die Fadensucheinrichtung direkt an die Arbeitsstelle bzw. die Arbeitsorgane der Arbeitsstelle übergeben werden. Grundsätzlich ist es jedoch ebenso denkbar, ein Übergabeorgan an der Arbeitsstelle anzuordnen, welches dann das Fadenende von der Saugdüse übernimmt und in die Aufnahmeposition überführt.According to a particularly advantageous embodiment of the method, the thread end is spent by means of a transfer member of the thread-seeking device in the receiving position at the workplace. In the textile machine, the at least one transfer element is correspondingly arranged on the thread search device. The thread search device includes in this case as working organs only a suction nozzle, a transfer member and possibly also a thread cutting device. The transfer member may for example be designed as a pivoting arm, movable hook, linearly movable or backdrop-guided feeder or as a pneumatic transfer member. The thread end can thus be passed through the thread-seeking device directly to the job or the work organs of the job. In principle, however, it is also conceivable to arrange a transfer member at the work station, which then takes over the thread end of the suction nozzle and transferred to the receiving position.
Bei einer Spinnmaschine befindet sich die Aufnahmeposition, aus welcher das Fadenende durch ein Arbeitsorgan, insbesondere ein arbeitsstelleneigenes Handlingsorgan, aufgenommen wird, vorzugsweise im Fadenlauf zwischen einem Ausgang der Spinnstelle und der Spulvorrichtung, insbesondere zwischen dem Ausgang der Spinnstelle und einer Abzugsvorrichtung der Spinnstelle. Dieser Bereich der Arbeitsstelle ist gut zugänglich, so dass das Fadenende durch die Fadensucheinrichtung bzw. das Übergabeorgan gut in diese Aufnahmeposition überführt werden kann.In a spinning machine, the receiving position, from which the thread end is received by a working organ, in particular a work-own handling element, preferably in the yarn path between an output of the spinning station and the winding device, in particular between the output of the spinning station and a take-off device of the spinning station. This area of the job is easily accessible, so that the thread end can be transferred by the thread-seeking device or the transfer member well into this receiving position.
Um im Falle einer planbaren Unterbrechung der Produktion das spulenseitige Fadenende in der Aufnahmeposition bereit zu stellen, ist es weiterhin vorteilhaft, wenn die Arbeitsstelle kontrolliert stillgesetzt wird bzw. kontrolliert stillsetzbar ist. Die Arbeitsorgane der Arbeitsstelle können hierzu kontrolliert und aufeinander abgestimmt bis zum Stillstand abgebremst werden, so dass das Fadenende schließlich in der definierten Aufnahmeposition stehen bleibt und nicht auf die Spule aufläuft. Eventuelle Wartezeiten auf die Fadensucheinrichtung werden hierdurch noch weiter verkürzt, da diese nur noch im Falle von ungeplanten Unterbrechungen der Produktion, bei welchen das Fadenende auf die Spule aufläuft, benötigt wird.In order to provide the coil-side thread end in the receiving position in the event of a plannable interruption of production, it is furthermore advantageous if the workstation is shut down in a controlled manner or can be stopped in a controlled manner. The work organs of the workstation can be controlled and coordinated with each other to decelerate to a standstill, so that the thread end eventually stops in the defined receiving position and does not run on the coil. Any waiting times on the thread search device are hereby further shortened, since these only in the case unplanned interruptions of production, in which the thread end runs onto the spool is needed.
Vorteilhaft ist es, wenn die Fadensucheinrichtung das Fadenende beim Verbringen in die Aufnahmeposition in den Wirkungsbereich eines pneumatischen Arbeitsorgans, insbesondere eines pneumatischen Handlingsorgans der Arbeitsstelle verbringt. Ein derartiges pneumatisches Handlingsorgan ist an den Arbeitsstellen meist ohnehin vorgesehen, um das Fadenende beim Anspinnvorgang fixieren zu können oder eine Fadenreserve zu bilden. Es kann jedoch auch ein zusätzliches pneumatisches Handlingsorgan zur Übernahme des Fadenendes von der Fadensucheinrichtung vorgesehen sein. Ebenso ist es auch möglich, dass das Fadenende direkt durch ein pneumatisches Arbeitsorgan der Arbeitsstelle, bei einer Spinnmaschine beispielsweise die Spinnvorrichtung, aufgenommen wird. Im Falle einer Rotorspinnmaschine kann das Fadenende beispielsweise durch die Abzugsdüse der Rotorspinnvorrichtung aufgenommen werden bzw. im Falle einer Luftspinnmaschine durch die Luftspinndüse. In jedem Fall kann das Fadenende hierdurch sehr schnell durch die Fadensucheinrichtung an die Arbeitsstelle übergeben werden, so dass Wartezeiten weiter reduziert werden.It is advantageous if the thread-seeking device spends the thread end when it is being brought into the receiving position into the area of action of a pneumatic working member, in particular a pneumatic handling member of the workstation. Such a pneumatic handling member is usually provided at the workstations anyway to be able to fix the thread end during piecing or to form a thread reserve. However, it may also be provided an additional pneumatic handling member for the takeover of the thread end of the thread search device. Likewise, it is also possible that the thread end directly by a pneumatic working member of the workplace, in a spinning machine, for example, the spinning device is recorded. In the case of a rotor spinning machine, the thread end can be received, for example, through the take-off nozzle of the rotor spinning device or, in the case of an air-spinning machine, through the air-spinning nozzle. In any case, the thread end can thereby be transferred very quickly through the thread-seeking device to the job, so that waiting times are further reduced.
Vorteilhaft ist es weiterhin, wenn die Fadensucheinrichtung das Fadenende beim Verbringen in die Aufnahmeposition zugleich in die Abzugsvorrichtung der Arbeitsstelle und/oder in einen Fadenführer der Spulvorrichtung und/oder in eine Garnüberwachungseinrichtung eingelegt. Das Fadenende wird somit direkt durch die Fadensucheinrichtung in eine Position im Fadenlauf verbracht, in welcher es sich auch nach einem kontrollierten Stillsetzen der Arbeitsstelle befinden würde. Zusätzliche Handlingseinrichtungen an der Arbeitsstelle sind somit nicht erforderlich. Grundsätzlich ist es jedoch auch denkbar, dass in der Aufnahmeposition das Fadenende durch die Fadensucheinrichtung lediglich an ein pneumatisches Handlingsorgan übergeben wird und von dort aus durch weitere arbeitsstelleneigenen Handlingsorgane in die die Abzugsvorrichtung und/oder in den Fadenführer und/oder in die Garnüberwachungseinrichtung eingelegt wird.It is also advantageous if the thread-seeking device at the same time inserted the thread end when moving into the receiving position in the take-off device of the job and / or in a yarn guide of the winding device and / or in a yarn monitoring device. The thread end is thus spent directly through the thread-seeking device in a position in the threadline, in which it would be even after a controlled shutdown of the job. Additional handling facilities at the workplace are therefore not required. In principle, however, it is also conceivable that in the receiving position, the thread end is passed through the thread-seeking device only to a pneumatic handling element and from there by further work-own handling organs in which the trigger device and / or in the thread guide and / or in the yarn monitoring device is inserted.
Bei einer besonders vorteilhaften Ausführung der Textilmaschine ist die Fadensucheinrichtung in Längsrichtung der Textilmaschine entlang mehrerer nebeneinander angeordneter Arbeitsstellen verfahrbar ist. Dabei ist es wiederum vorteilhaft, wenn die Fadensucheinrichtung mittels eines eigenen Fahrantriebs verfahrbar ist. Denkbar ist es jedoch auch, einen Antrieb für die Fadensucheinrichtung an der Textilmaschine anzuordnen und die Fadensucheinrichtung mittels eines Kopplungselements, beispielsweise eines Riementriebs, mit dem Antrieb zu verbinden. Eine derartige, verfahrbare Fadensucheinrichtung kann besonders platzsparend ausgeführt werden, so dass die Anordnung der Arbeitsorgane der Arbeitsstelle hierdurch konstruktiv einfacher wird.In a particularly advantageous embodiment of the textile machine, the thread-seeking device is movable in the longitudinal direction of the textile machine along a plurality of workstations arranged next to one another. It is again advantageous if the thread-seeking device can be moved by means of its own traction drive. However, it is also conceivable to arrange a drive for the thread-seeking device on the textile machine and to connect the thread-seeking device to the drive by means of a coupling element, for example a belt drive. Such a movable thread search device can be made particularly space-saving, so that the arrangement of the working organs of the job is thereby structurally easier.
Ist die Textilmaschine als doppelseitige Textilmaschine vorgesehen, so kann eine derartige, in Längsrichtung der Textilmaschine verfahrbare Fadensucheinrichtung einfach und platzsparend ausgeführt werden, wenn diese mittig zwischen zwei Längsseiten der Textilmaschine verfahrbar ist. Die Fadensucheinrichtung kann dabei für jede der beiden Längsseiten separate Arbeitsorgane, also jeweils eine Saugdüse und ggf. jeweils ein Übergabeorgan beinhalten. Alternativ kann für beide Längsseiten der Textilmaschine eine gemeinsame Saugdüse vorgesehen sein, die den beiden Längsseiten bzw. deren Arbeitsstellen im Wechsel zustellbar ist. Die gemeinsame Saugdüse und ggf. ein gemeinsames Übergabeorgan kann hierzu beispielsweise schwenkbar oder nach beiden Längsseiten hin klappbar auf einem verfahrbaren Gestell angeordnet sein.If the textile machine is provided as a double-sided textile machine, such a thread search device which can be moved in the longitudinal direction of the textile machine can be designed in a simple and space-saving manner if it can be moved centrally between two longitudinal sides of the textile machine. The thread-seeking device can contain separate working members for each of the two longitudinal sides, ie in each case a suction nozzle and, if appropriate, in each case a transfer element. Alternatively, a common suction nozzle can be provided for both longitudinal sides of the textile machine, which can be delivered to the two longitudinal sides or their workstations alternately. For this purpose, the common suction nozzle and, if appropriate, a common transfer element can, for example, be arranged so as to be pivotable or foldable on both sides along a movable frame.
Nach einer anderen vorteilhaften Weiterbildung ist die Fadensucheinrichtung zwischen wenigstens zwei Arbeitsstellen der Textilmaschine hin- und her bewegbar an der Textilmaschine angeordnet. Beispielsweise kann eine Fadensucheinrichtung jeweils zwischen zwei in Längsrichtung nebeneinander liegenden Arbeitsstellen angeordnet sein und zwischen diesen hin- und her schwenkbar sein. Zusätzlich kann die Fadensucheinrichtung auch derart klappbar und/oder ggf. auch teleskopierbar sein, dass beispielsweise vier nebeneinander liegende Arbeitsstellen bedient werden können.According to another advantageous development, the thread-seeking device is arranged to be movable back and forth between at least two work stations of the textile machine on the textile machine. For example, a thread search device each side between two in the longitudinal direction be located at work and pivot between these back and forth. In addition, the thread-seeking device can also be foldable and / or if necessary also be telescoped so that, for example, four workstations lying next to one another can be operated.
Nach einer vorteilhaften Ausführung der Textilmaschine umfassen weiterhin die arbeitsstelleneigenen Handlingsorgane zumindest eine Fadentrenneinheit zum Ablängen des Fadenendes, eine Fadenvorbereitungseinheit zum Vorbereiten des abgelängten Fadenendes und eine Rückführeinheit zum Rückführen des vorbereiteten Fadenendes in die Spinnstelle und oder zu einer Verbindungsstelle. Die Verbindungsstelle liegt im Falle einer Spulmaschine im Bereich eines Spleißers. Im Falle einer Spinnmaschine kann diese auch außerhalb der Spinnstelle gelegen sein. Die Rückführeinheit kann dabei sowohl durch eine zusätzliche Einrichtung, beispielsweise ein Hilfswalzenpaar ausgeführt sein, oder durch die reguläre Abzugsvorrichtung gebildet werden.According to an advantageous embodiment of the textile machine, the workstation's own handling devices further comprise at least one thread separation unit for cutting the thread end, a thread preparation unit for preparing the cut thread end and a return unit for returning the prepared thread end into the spinning station and / or to a connection point. The connection point is in the case of a winder in the region of a splicer. In the case of a spinning machine, this may also be located outside the spinning station. The return unit can be executed both by an additional device, such as an auxiliary roller pair, or be formed by the regular deduction device.

Weiterhin ist an der Arbeitsstelle 2 eine Reihe von Handlingsorganen 10, 16, 17, 18 vorgesehen, mittels welchen nach einer Unterbrechung der Produktion, hier des Spinnprozesses, ein spulenseitiges Fadenende 6 wieder angesponnen werden kann. Das Fadenende 6 wird hierzu durch eine Fadentrenneinheit 16 abgelängt, durch eine Fadenvorbereitungseinheit 17 zum Anspinnen vorbereitet und durch eine Rückführeinheit 18 in die Spinnstelle bzw. durch die Spinnstelle 3 hindurch zu einer Verbindungsstelle 19 außerhalb der Spinnstelle 3 zurückgeführt. Vorliegend wird die Rückführeinheit 18 durch die Abzugsvorrichtung 9 der Arbeitsstelle gebildet, welche zum Rückliefern des Fadenendes 6 entgegengesetzt der regulären Abzugsrichtung angetrieben wird. Die Rückführeinheit 18 kann jedoch ebenso als separate Einheit, beispielsweise als Hilfswalzenpaar, ausgeführt sein.Furthermore, a number of
Vorliegend ist an der Arbeitsstelle 2 auch ein pneumatisches Handlingsorgan 10 angeordnet, um das Fadenende 6 vorübergehend zu fixieren. Dies ist jedoch nicht unbedingt erforderlich, je nach Anordnung der einzelnen Baugruppen und Handlingsorgane 16, 17, 18 an der Arbeitsstelle 2 ist es auch möglich, das Fadenende 6 mittels der Abzugsvorrichtung 9 zu fixieren. Weiterhin kann ein pneumatisches Handlingsorgan 10 zum Fixieren des Fadenendes 6 oder zum Bilden einer Fadenreserve beim Wiederanspinnen auch an anderer Stelle innerhalb des Fadenlaufs an der Arbeitsstelle 2 vorgesehen sein oder es können mehrere pneumatische Handlingsorgane 10 vorhanden sein. Schließlich ist es abweichend von der gezeigten Darstellung auch möglich, dass nicht an jeder Arbeitsstelle 2 Handlingsorgane 10, 16, 17, 18 angeordnet sind, sondern diese arbeitsstelleneigenen Handlingsorgane 10, 16, 17, 18 beispielsweise jeweils für zwei Arbeitsstellen 2 gemeinsam vorgesehen sind.In the present case, a
Die vorliegende Darstellung zeigt nun eine Situation an der Arbeitsstelle 2 nach einer gezielten Unterbrechung des Spinnprozesses. Ein derartiges kontrolliertes Stillsetzen kann bei jedem planbaren Spinnstopp erfolgen, also beispielsweise zur Beseitigung eines Garnfehlers, zum Spulenwechsel oder zum Abschalten der Arbeitsstelle 2 oder der Spinnmaschine. Hierfür werden die Fördergeschwindigkeiten der einzelnen Arbeitsorgane 27, 9, 4 der Arbeitsstelle 2, hier zumindest der Lieferwalzen 27, der Abzugsvorrichtung 9 und der Spulvorrichtung 4 allmählich und aufeinander abgestimmt bis zum Stillstand reduziert. Die Antriebe der einzelnen Arbeitsorgane 27, 9, 4 sind hierzu mit einzeln ansteuerbaren Antrieben (nicht dargestellt) ausgestattet, welche durch eine Steuereinrichtung (nicht dargestellt) der Arbeitsstelle 2 oder der Spinnmaschine 1 entsprechend ansteuerbar sind. Das Fadenende 6 läuft hierdurch nicht auf die Spule auf, sondern befindet sich in einer definierten Aufnahmeposition A zwischen einem Ausgang 8 der Spinnstelle 3 und der Spulvorrichtung 4. Von dort aus kann es problemlos von den Handlingsorganen 10, 16, 17, 18 der Arbeitsstelle 2 aufgenommen werden und wiederangesponnen werden. Da das spulenseitige Fadenende 6 dabei im Wesentlichen in seinem regulären Fadenlauf verbleibt, muss es nach dem Anspinnen auch nicht mehr an die Arbeitsorgane der Arbeitsstelle 2, insbesondere die Abzugsvorrichtung 9, die Garnüberwachungseinrichtung 15 sowie den Fadenführer 11 eingelegt werden. Die Aufnahmeposition A befindet sich vorliegend zwischen dem Ausgang 8 der Spinnstelle 3 und der Abzugsvorrichtung 9. Die Fadensucheinrichtung nach der vorliegenden Erfindung, insbesondere eine verfahrbare Fadensucheinrichtung für eine Vielzahl von Arbeitsstellen, kann an einer Spinnmaschine, deren Arbeitsstellen kontrolliert stillsetzbar sind, besonders vorteilhaft eingesetzt werden. Bei derartigen Maschinen wird die Fadensucheinrichtung nur noch im Fall von ungeplanten Unterbrechungen des Spinnprozesses benötigt, so dass nur wenige oder sogar nur eine Fadensucheinrichtung je Spinnmaschine vorzusehen ist. Eine zwischen mehreren Arbeitsstellen bewegbare Fadensucheinrichtung ist jedoch auch an herkömmlichen Arbeitsstellen ohne die Möglichkeit des kontrollierten Stillsetzens vorteilhaft.The present illustration now shows a situation at the
Tritt nun eine unvorhergesehene Unterbrechung des Spinnprozesses, beispielsweise durch Fadenbruch, auf, so läuft das spulenseitige Fadenende 6 auf die Oberfläche der Spule 5 auf. Um in einem solchen Fall ebenfalls eine Wiederaufnahme des Spinnprozesses zu ermöglichen, ist die verfahrbare Fadensucheinrichtung 7 vorgesehen. Die Fadensucheinrichtung 7 kann sich an der betreffenden Arbeitsstelle 2 positionieren und mittels der beweglichen Saugdüse 12 das Fadenende 6 auf der Spule 5 aufsuchen. Die Spule 5 wird hierzu durch einen nicht dargestellten Antrieb an der Arbeitsstelle 2 entgegen ihrer regulären Drehrichtung angetrieben, so dass das Fadenende 6 in die Saugdüse 12 eingesaugt werden kann. Nach erfolgreicher Aufnahme des Fadenendes 6 in die Saugdüse 12, was durch einen Sensor detektiert werden kann, wird das Fadenende 6 durch das Übergabeorgan 13 von der Saugdüse 12 aufgenommen und dem pneumatischen Handlingsorgan 10 der Arbeitsstelle 2 in Form einer Fadenschlaufe übergeben. Das Fadenende 6 liegt nun in der definierten Aufnahmeposition A vor.If now an unforeseen interruption of the spinning process, for example due to yarn breakage, on, then the coil-
Beim Verbringen des Fadenendes 6 in die Aufnahmeposition A wird das Fadenende 6 dabei zugleich in die Arbeitsorgane der Spinnstelle, vorliegend zumindest die Garnüberwachungseinrichtung 15, und die Abzugsvorrichtung 9 eingelegt, so dass das Fadenende 6 ebenso wie zuvor zu
Dadurch, dass die Fadensucheinrichtung 7 vorliegend bezüglich des Ansetzvorgangs ausschließlich die beiden Funktionen der Fadensuche und - übergabe ausführen muss, während sich die Handlingsorgane zum Anspinnen 10, 16, 17, 18 an der Arbeitsstelle 2 befinden, kann die Fadensucheinrichtung 7 konstruktiv sehr einfach ausgeführt werden und kostengünstig hergestellt werden. Nach einer anderen Ausführung kann die Fadensucheinrichtung zusätzlich noch eine Schneidfunktion ausführen, wobei die Fadensucheinrichtung 7 jedoch noch immer sehr einfach und kostengünstig ausgeführt werden kann. Zudem kann die Fadensucheinrichtung 7 nach der Übergabe des Fadenendes 6 sofort die nächste Arbeitsstelle 2, an welcher ein Fadenbruch aufgetreten ist, aufsuchen. Da zudem die Fadensucheinrichtung 7 lediglich im Fall eines unvorhergesehenen, vergleichsweise seltenen Fadenbruchs, nicht jedoch bei planbaren Unterbrechungen des Spinnbetriebs benötigt wird, können Wartezeiten an den Arbeitsstellen 2 mit entsprechenden Produktionsausfällen nahezu vollständig vermieden werden.Characterized in that the thread-seeking
Vorliegend ist die Saugdüse 12 schwenkbeweglich ausgeführt und weist hierfür einen Antrieb 14 auf. Die Saugdüse 12 könnte jedoch ebenso linear beweglich ausgeführt werden oder in sonstiger Weise der Spule 5 zustellbar sein. Es ist auch nicht unbedingt erforderlich, ein gesondertes Übergabeorgan 13 vorzusehen. Je nach Ausführung und Bewegbarkeit der Saugdüse kann das Fadenende 6 auch direkt durch die Saugdüse 12 in die Aufnahmeposition A an der Arbeitsstelle 2 verbracht werden. Ebenso ist es auch denkbar, mehrere Übergabeorgane 13 in der Fadensucheinrichtung 7 anzuordnen, um den Faden F in die Arbeitsorgane der Spinnmaschine, insbesondere die Abzugsvorrichtung 9, die Garnüberwachungseinrichtung 15 sowie den Fadenführer 11, einlegen zu können bzw. diesen an die Handlingsorgane 10, 16, 17, 18 zu übergeben. Abweichend von der hier gezeigten Darstellung kann schließlich auch noch eine Schneideinrichtung für den Faden an der Fadensucheinrichtung vorgesehen sein.In the present case, the
Die Arbeitsstellen 2 der Spinnmaschine 1 der

Vorliegend dargestellt ist wiederum eine Situation, in der ein auf die Spule 5 aufgelaufenes Fadenende 6 bereits durch die Saugdüse 12 aufgenommen und durch das Übergabeorgan 13 in die definierte Aufnahmeposition A verbracht wurde, in welcher es nun in Form einer Fadenschlaufe vorliegt. Das Fadenende 6 ist in der Aufnahmeposition A in dem Handlingsorgan 10 aufgenommen und fixiert. Nachdem das Garn nun in der definierten Aufnahmeposition vorliegt, kann es wiederum wie beim Anspinnen nach einem kontrollierten Stillsetzen durch die Fadentrenneinheit 16 abgelängt, durch die Fadenvorbereitungseinheit 17 zum Wiederanspinnen vorbereitet und durch die Rückführeinheit 18 über den Ausgang 8 der Spinnstelle 3 in diese zurückgeführt werden.In the present case, in turn, a situation in which a
Die beschriebene Fadensuchvorrichtung 7 kann in verschiedenen Textilmaschinen wie Spulmaschinen, Luftspinnmaschinen oder Rotorspinnmaschinen eingesetzt werden. Da die Fadensucheinrichtung 7 jeweils nur kurz zur Fadensuche und -übergabe an einer Arbeitsstelle 2 im Einsatz ist, während sämtliche zeitintensiven Arbeiten des Anspinnprozesses, insbesondere das Ablängen und Vorbereiten des Fadenendes 6, direkt durch die Arbeitsstelle 2 ausgeführt werden, ergibt sich ein erheblicher Zeitvorteil gegenüber einer herkömmlichen Wartungseinrichtung. Die Fadensucheinrichtung 7 kann nach erfolgter Fadenübergabe in die Aufnahmeposition sofort die nächste Arbeitsstelle aufsuchen, so dass Wartezeiten mit entsprechenden Produktionsausfällen vermieden werden können. Zur Vermeidung von Wartezeiten trägt es im Falle einer kontrolliert stillsetzbaren Arbeitsstelle weiterhin bei, dass planbare Unterbrechungen des Spinnprozesses ohne die Fadensucheinrichtung 7 abgearbeitet werden können, so dass diese nur noch in den vergleichsweise wenigen Fällen unvorhersehbarer Fadenbrüche zum Einsatz kommen muss. Da die verfahrbare Fadensucheinrichtung 7 eine Vielzahl von Arbeitsstellen 2 in kurzer Zeit nacheinander bedienen kann, ist es nicht erforderlich, eine kostenintensive Fadensucheinrichtung mit einem hohen Platzbedarf an jeder der Arbeitsstellen 2 anzuordnen. Vorteilhaft ist es weiterhin, dass die Anzahl der Fadensucheinrichtungen 7 an einer Textilmaschine problemlos an verschiedene Maschinenlängen bzw. verschiedene Anzahlen von Arbeitsstellen 2 oder auch die zu erwartende Fadenbruchrate angepasst werden kann. Die vorgeschlagene Fadensucheinrichtung 7 kann zudem sehr kostengünstig hergestellt werden, da sie neben ihren Grundkomponenten wie dem Gestell 20, dem Fahrwerk 21 sowie Einrichtungen zur Energieversorgung und Steuerung, als Arbeitsorgane lediglich eine Saugdüse 12 und ein oder mehrere Übergabeorgane 13 aufweist.The described yarn-searching
