Definitions
- the present invention relates to a cheese-making textile machine with a large number of work stations arranged next to one another and with a vacuum system.
- Each of the work stations has a suction nozzle that can be subjected to negative pressure for locating an end of the thread on a spool and a thread storage nozzle that can be subjected to negative pressure for temporarily taking up excess thread length.
- the suction nozzle and the yarn storage nozzle are each connected to the vacuum system by means of a suction line and can be shut off from the vacuum system independently of one another by means of their own shut-off device.
- a vacuum system is always present on cross-bobbin-producing textile machines such as spinning machines or winding machines, which supplies the working elements at the individual work stations with vacuum.
- negative pressure is required for maintenance functions such as, for example, using a suction nozzle to search for a thread end that has run onto the bobbin after a thread breaks.
- negative pressure is required in order to be able to store a temporary, excess thread length by means of a thread storage nozzle and/or to keep the thread under tension while the work station is running up. Vacuum is also often required for cleaning processes and other maintenance processes.
- spinning machines in particular rotor spinning machines, negative pressure is also required for the regular production process.
- the DE 10 2006 047 288 A1 has therefore already suggested that the suction nozzle and the yarn storage nozzle should no longer be connected to the vacuum system together, but rather separately. At least the suction nozzle is connected to the vacuum system by means of its own shut-off means and can therefore be decoupled from the vacuum as soon as it is no longer needed. Since the air consumption of the suction nozzle is very high, this means that more suction air is available for other jobs.
- the yarn storage nozzle which requires less suction air, on the other hand, can remain connected to the vacuum network until the run-up process is complete.
- the suction nozzle and the yarn storage nozzle can be pressurized and shut off together via a common connection line. According to an alternative embodiment, the yarn storage nozzle can also be connected to the vacuum system by means of its own shut-off means. The suction air consumption can be reduced as a result, but the structure of the textile machine is comparatively complex.
- a textile machine that produces cross-wound bobbins has a large number of similar work stations arranged next to one another and a vacuum system.
- Each of the work stations has a suction nozzle that can be subjected to negative pressure for locating a thread end on a bobbin and a thread storage nozzle that can be subjected to negative pressure for temporarily taking up an excess thread length during a piecing or splicing process.
- the suction nozzle and the yarn storage nozzle are each connected to the vacuum system by means of a suction line and can be shut off from the vacuum system independently of one another by means of their own shut-off device.
- a piecing process is understood to mean both a piecing process on a spinning machine and a splicing process on a winding machine.
- preparation process or preparation process
- the suction nozzles of two adjacent work stations each be assigned a common shut-off device.
- the textile machine has a significantly simpler structure, since a shut-off element together with its actuating device only has to be arranged at every second work station. The control effort for actuating the shut-off element is also reduced.
- the textile machine can be manufactured much more cost-effectively, since only half as many shut-off devices are required as before. Nevertheless, each suction nozzle can supply a sufficient amount of Suction air can be made available as soon as it is needed.
- the invention is based on the finding that two adjacent work stations do not usually start a run-up process at the same time, since it is extremely unlikely that a thread will have to be reattached at both work stations at the same time. Since, in addition, on modern textile machines with so-called autonomous jobs, the individual jobs are independent of one another, it is not necessary during a starting process to start adjacent jobs at the same time or in immediate succession. In addition, on such a textile machine, among other things, due to the limited resources of compressed air, suction air and electricity, several work stations are usually always started with a certain time lag. It is therefore possible to jointly shut off the suction nozzles of two neighboring work stations from the vacuum network without unnecessary waiting times or loss of productivity occurring as a result.
- the thread storage nozzles of two adjacent work stations each be assigned a common shut-off device. This also allows the same advantages to be achieved as with the suction nozzles described above. Although the thread storage nozzles have a slightly lower suction air requirement than the suction nozzles, they are usually in operation throughout the entire piecing process, so that advantages in terms of operating costs can also be achieved here in addition to the reduced production costs.
- the shut-off device has a common shut-off element for each of the two adjacent work stations, which can be controlled in a defined manner by a drive, in particular a stepper motor.
- the production costs can be further reduced as a result.
- the shut-off element can be controlled in a defined manner in a particularly favorable manner by means of a stepping motor, and it can thus be ensured that the shut-off element is actually in the desired position.
- the shut-off element can be brought into at least three different positions by means of the drive, with the shut-off element shutting off the suction nozzles of the two adjacent work stations in a first position, only shutting off the suction nozzle of a first of the two work stations in a second position and in one third position only shuts off the suction nozzle of a second of the two work stations.
- the suction nozzle of the respective other work station thus remains connected to the vacuum system and can be subjected to vacuum accordingly. This makes it possible to make suction air available to the suction nozzles of adjacent work stations independently of one another at different times and thereby to take into account the suction air requirement at the two work stations that differs over time.
- shut-off element can be moved into at least three different positions by means of the drive, with the shut-off element shutting off the yarn storage nozzles of the two adjacent work stations in a first position, only the yarn storage nozzle of a first of the two work stations blocked in a second position and in one third position only the yarn storage nozzle of a second of the two jobs cordoned off.
- the thread storage nozzle of the respective other work station remains connected to the vacuum system and can be subjected to vacuum until the end of the piecing process.
- a suction cross-section of the respective suction line can be regulated by means of the shut-off element. This can be done, for example, by the shut-off element being able to be moved into one or more intermediate positions in which it only partially opens up the cross-section of the suction line. The supply of suction air to the respective suction nozzle or the respective thread storage nozzle can thereby be adjusted according to need. It is also advantageous if the shut-off element can be moved steplessly between the second and the third position in order to open or close the suction cross section according to the respective needs.
- the shut-off element is designed as a sliding valve.
- the slide valve includes a slide that is provided with at least one through opening, the cross section of which corresponds approximately to a cross section of the respective suction line.
- the slide can be moved translationally by means of a drive.
- a shut-off element with a slide of this type can be produced in a particularly simple and cost-effective manner.
- the shut-off element is designed as a rotary valve.
- the rotary valve in turn contains at least one passage opening, which can be arranged both along the axis of rotation and transversely to the axis of rotation of the rotary valve.
- Several passage openings are also possible with the rotary valve.
- Such a rotary valve can be arranged in a particularly space-saving manner inside a suction line.
- the shut-off device is connected to a workplace controller via a control line.
- the shut-off device can be actuated by the workplace control in cooperation with other organs of the workplace exactly when this is necessary in the piecing process.
- the workplace control is preferably designed as a group controller for at least two workplaces, preferably for four workplaces. This makes it easy to coordinate the processes at the individual neighboring work stations.
- suction lines of the suction nozzle and the thread storage nozzle open into a common connecting line in an opening area, by means of which they are connected to the vacuum system. This further simplifies the construction of the textile machine. In addition, cost advantages are also achieved as a result.
- shut-off element is arranged in the mouth area. As a result, it can be accommodated in a particularly space-saving manner.
- FIG 1 shows a front view of a textile machine 1 in a schematic overview.
- the textile machine 1 has a multiplicity of work stations 2 arranged next to one another, which in the present case are arranged between two frames 24 in each case.

- the thread 8 is drawn off by means of a take-off device 10 , fed to a winding device 26 and wound onto a bobbin 6 there.
- a take-off device 10 is not required, since there the thread is taken off directly by the winding device.
- a large number of other working elements and maintenance elements for handling the thread 8 can be arranged in the thread path between the delivery device 9 and the winding device 26. These are not described in detail here.
- a paraffining device 25 is shown here merely as an example.
- the textile machine 1 also has a central control unit 12, which is arranged in one of the frames 24 in the present case.

- the suction nozzle it is also possible for the suction nozzle to be pivotably arranged at the work site.
- each of the work stations 2 has a thread storage nozzle 4, which is specific to the work station and is directed towards the thread path, for taking up a temporary excess thread.

Furthermore, the periods of time over which negative pressure is required are also different. The suction nozzle 5 only needs vacuum for a relatively short time, while the yarn storage nozzle 4 needs suction air for almost the entire piecing process after the yarn end has been found.
- the suction nozzles 5 and the thread storage nozzles 4 of the individual work stations 2 can be separated from the vacuum system independently of one another, as is now the case on the basis of FIG figure 2 is explained.

- the shut-off elements 18 could also be controlled directly by the control unit 12.
- the course of the thread 8 through the suction nozzle 5 during production is clearly visible.

- FIG. 4a now shows the shut-off element 18 in a first position I, in which it shuts off the yarn storage nozzles 4 of the two adjacent work stations 2 and thus separates them from the vacuum network.
- Figure 4b shows the blocking element 18 in a second position II, in which it blocks the thread storage nozzle 4 of the first of the two work stations 2, here the left work station 2, and the thread storage nozzle 4 of the second work station 2, here the right work station 2, is released.

- shut-off element 18 was shifted slightly to the right, so that it is in an intermediate position in which it does not completely but only partially releases the cross-section of the left-hand suction line 3 .

Description
Die vorliegende Erfindung betrifft eine kreuzspulenherstellende Textilmaschine mit einer Vielzahl nebeneinander angeordneter Arbeitsstellen und mit einem Unterdrucksystem. Jede der Arbeitsstellen weist eine mit Unterdruck beaufschlagbare Saugdüse zum Aufsuchen eines Fadenendes auf einer Spule sowie eine mit Unterdruck beaufschlagbare Fadenspeicherdüse zum temporären Aufnehmen einer Fadenüberlänge auf. Die Saugdüse und die Fadenspeicherdüse sind mittels jeweils einer Saugleitung an das Unterdrucksystem angeschlossen und mittels jeweils einer eigenen Absperreinrichtung unabhängig voneinander von dem Unterdrucksystem absperrbar.The present invention relates to a cheese-making textile machine with a large number of work stations arranged next to one another and with a vacuum system. Each of the work stations has a suction nozzle that can be subjected to negative pressure for locating an end of the thread on a spool and a thread storage nozzle that can be subjected to negative pressure for temporarily taking up excess thread length. The suction nozzle and the yarn storage nozzle are each connected to the vacuum system by means of a suction line and can be shut off from the vacuum system independently of one another by means of their own shut-off device.
An kreuzspulenherstellenden Textilmaschine wie Spinnmaschinen oder Spulmaschinen ist stets ein Unterdrucksystem vorhanden, welches die Arbeitsorgane an den einzelnen Arbeitsstellen mit Unterdruck versorgt. Beispielsweise wird an Textilmaschinen Unterdruck für Wartungsfunktionen wie beispielsweise das Aufsuchen eines auf die Spule aufgelaufenen Fadenendes nach einem Fadenbruch mittels einer Saugdüse benötigt. Ebenso wird im Rahmen eines Ansetz- oder Spleißvorganges Unterdruck benötigt, um während des Hochlaufens der Arbeitsstelle mittels einer Fadenspeicherdüse eine temporäre, überschüssige Fadenlänge speichern zu können und/oder den Faden unter Spannung zu halten. Auch für Reinigungsvorgänge sowie weitere Wartungsvorgänge ist oftmals Unterdruck erforderlich. An Spinnmaschinen, insbesondere Rotorspinnmaschinen wird zudem auch für den regulären Produktionsprozess Unterdruck benötigt.A vacuum system is always present on cross-bobbin-producing textile machines such as spinning machines or winding machines, which supplies the working elements at the individual work stations with vacuum. For example, on textile machines, negative pressure is required for maintenance functions such as, for example, using a suction nozzle to search for a thread end that has run onto the bobbin after a thread breaks. Likewise, as part of a piecing or splicing process, negative pressure is required in order to be able to store a temporary, excess thread length by means of a thread storage nozzle and/or to keep the thread under tension while the work station is running up. Vacuum is also often required for cleaning processes and other maintenance processes. On spinning machines, in particular rotor spinning machines, negative pressure is also required for the regular production process.
Während bei früheren Textilmaschinen die Saugdüse und die Fadenspeicherdüse in einer entlang der Arbeitsstellen verfahrbaren Wartungseinrichtung angeordnet waren, sind diese bei modernen Spinnmaschinen direkt an jeder einzelnen Arbeitsstelle vorgesehen. Vorteilhaft bei derartigen Textilmaschinen ist es, dass die Arbeitsstellen im Falle einer Unterbrechung der Produktion nicht auf eine verfahrbare Wartungseinrichtung warten müssen, sondern den Faden selbstständig wieder ansetzen bzw. spleißen können. Dabei können auch an mehreren Arbeitsstellen gleichzeitig Ansetz- bzw. Spleißvorgänge durchgeführt werden. Da für die Ansetz- bzw. Spleißvorgänge, insbesondere die Fadensuche, jedoch vergleichsweise viel Saugluft benötigt wird, ist die Anzahl der Arbeitsstellen, die gleichzeitig einen Ansetz- bzw. Spleißvorgang durchführen können, limitiert. Zudem entsteht ein relativ hoher Energieverbrauch.While in earlier textile machines the suction nozzle and the yarn storage nozzle were arranged in a maintenance device that can be moved along the work stations, in modern spinning machines these are provided directly at each individual work station. It is advantageous with such textile machines that the work stations do not have to wait for a mobile maintenance device in the event of an interruption in production, but can independently attach or splice the thread again. Attachment or splicing processes can also be carried out at several work stations at the same time. However, since the piecing or splicing processes, in particular the thread search, require a comparatively large amount of suction air, the number of workstations that can simultaneously carry out a piecing or splicing process is limited. In addition, there is a relatively high energy consumption.
Die
Aufgabe der vorliegenden Erfindung ist es deshalb, den Aufbau einer kreuzspulenherstellenden Textilmaschine zu vereinfachen und dabei dennoch einen reduzierten Saugluftverbrauch zu ermöglichen.It is therefore the object of the present invention to simplify the structure of a textile machine that produces cross-wound bobbins and, at the same time, to enable reduced suction air consumption.
Die Aufgabe wird gelöst mit den Merkmalen des Anspruchs 1.The object is solved with the features of

The suction nozzle and the yarn storage nozzle are each connected to the vacuum system by means of a suction line and can be shut off from the vacuum system independently of one another by means of their own shut-off device.
Im Rahmen dieser Anmeldung wir unter einem Ansetzprozess sowohl ein Anspinnprozess an einer Spinnmaschine als auch ein Spleißprozess an einer Spulmaschine verstanden. Es werden daher im Folgenden vereinfachend nur noch die Begriffe "Ansetzprozess" oder Ansetzvorgang" verwendet.In the context of this application, a piecing process is understood to mean both a piecing process on a spinning machine and a splicing process on a winding machine. For the sake of simplicity, only the terms “preparation process” or preparation process” will be used below.
Bei einer solchen Textilmaschine wird nun vorgeschlagen, dass den Saugdüsen jeweils zweier benachbarter Arbeitsstellen eine gemeinsame Absperreinrichtung zugeordnet ist. Die Textilmaschine weist hierdurch einen wesentlichen einfacheren Aufbau auf, da nur noch an jeder zweiten Arbeitsstelle ein Absperrelement mitsamt seiner Betätigungseinrichtung angeordnet werden muss. Auch der Steuerungsaufwand für die Betätigung des Absperrelements ist reduziert. Zudem kann die Textilmaschine wesentlich kostengünstiger hergestellt werden, da nur noch halb so viele Absperreinrichtungen wie zuvor erforderlich sind. Dennoch kann jeder Saugdüse eine ausreichende Menge an Saugluft zur Verfügung gestellt werden, sobald diese benötigt wird. Die Erfindung basiert auf der Erkenntnis, dass zwei benachbarte Arbeitsstellen in der Regel nicht gleichzeitig einen Hochlaufvorgang starten, da es höchst unwahrscheinlich ist, dass an beiden Arbeitsstellen gleichzeitig ein Faden wieder angesetzt werden muss. Da zudem an modernen Textilmaschinen mit sog. autarken Arbeitsstellen die einzelnen Arbeitsstellen unabhängig voneinander sind, ist es auch im Rahmen eines Startvorgang nicht erforderlich, benachbarte Arbeitsstellen zeitgleich oder unmittelbar nacheinander zu starten. Zudem werden an einer solchen Textilmaschine u.a. aus Gründen der beschränkten Ressourcen an Druckluft, Saugluft und Strom mehrere Arbeitsstellen in der Regel immer mit einem gewissen Zeitversatz gestartet. Deshalb ist es möglich, die Saugdüsen zweier benachbarter Arbeitsstellen gemeinsam von dem Unterdrucknetz abzusperren, ohne dass es hierdurch zu unnötigen Wartezeiten oder Produktivitätsverlusten kommt. Die Ausführung mit einer Absperreinrichtung für jeweils zwei Saugdüsen benachbarter Arbeitsstellen ist wesentlich einfacher und kostengünstiger, ermöglicht aber dennoch die Versorgung mit Saugluft exakt zu den benötigten Zeitpunkten und damit einen reduzierten Saugluftverbrauch. Insbesondere bei der Saugdüse für die Fadensuche, die einen vergleichsweise hohen Saugluftbedarf hat, lassen sich hierdurch nennenswerte Ersparnisse an Saugluft erzielen, so dass die Textilmaschine auch sehr wirtschaftlich betrieben werden kann.In such a textile machine, it is now proposed that the suction nozzles of two adjacent work stations each be assigned a common shut-off device. As a result, the textile machine has a significantly simpler structure, since a shut-off element together with its actuating device only has to be arranged at every second work station. The control effort for actuating the shut-off element is also reduced. In addition, the textile machine can be manufactured much more cost-effectively, since only half as many shut-off devices are required as before. Nevertheless, each suction nozzle can supply a sufficient amount of Suction air can be made available as soon as it is needed. The invention is based on the finding that two adjacent work stations do not usually start a run-up process at the same time, since it is extremely unlikely that a thread will have to be reattached at both work stations at the same time. Since, in addition, on modern textile machines with so-called autonomous jobs, the individual jobs are independent of one another, it is not necessary during a starting process to start adjacent jobs at the same time or in immediate succession. In addition, on such a textile machine, among other things, due to the limited resources of compressed air, suction air and electricity, several work stations are usually always started with a certain time lag. It is therefore possible to jointly shut off the suction nozzles of two neighboring work stations from the vacuum network without unnecessary waiting times or loss of productivity occurring as a result. The version with a shut-off device for each two suction nozzles of adjacent work stations is much simpler and more economical, but still enables the supply of suction air exactly at the required time and thus reduced suction air consumption. Significant savings in suction air can be achieved in this way, particularly in the case of the suction nozzle for thread search, which has a comparatively high suction air requirement, so that the textile machine can also be operated very economically.
Zusätzlich oder alternativ wird vorgeschlagen, dass den Fadenspeicherdüsen jeweils zweier benachbarter Arbeitsstellen eine gemeinsame Absperreinrichtung zugeordnet ist. Auch hierdurch lassen sich dieselben Vorteile wie bei den zuvor beschriebenen Saugdüsen erzielen. Die Fadenspeicherdüsen haben zwar einen etwas geringeren Saugluftbedarf als die Saugdüsen, sind jedoch in der Regel über den gesamten Ansetzprozess in Betrieb, so dass sich auch hier zusätzlich zu den reduzierten Produktionskosten Vorteile bei den Betriebskosten erzielen lassen.In addition or as an alternative, it is proposed that the thread storage nozzles of two adjacent work stations each be assigned a common shut-off device. This also allows the same advantages to be achieved as with the suction nozzles described above. Although the thread storage nozzles have a slightly lower suction air requirement than the suction nozzles, they are usually in operation throughout the entire piecing process, so that advantages in terms of operating costs can also be achieved here in addition to the reduced production costs.
Vorteilhaft ist es, wenn die Absperreinrichtung ein gemeinsames Absperrelement für die jeweils zwei benachbarten Arbeitsstellen aufweist, welches durch einen Antrieb, insbesondere einen Schrittmotor, definiert ansteuerbar ist. Die Produktionskosten können hierdurch noch weiter reduziert werden. Grundsätzlich wäre es jedoch auch möglich, zwei separate Absperrelemente vorzusehen, die mittels eines gemeinsamen Antriebs angesteuert werden. Mittels eines Schrittmotors kann das Absperrelement in besonders günstiger Weise definiert angesteuert werden und damit sichergestellt werden, dass sich das Absperrelement tatsächlich in der gewünschten Position befindet. Ebenso wäre es jedoch auch denkbar, das Absperrelement mittels eines oder vorzugsweise mehrerer Pneumatikzylinder zu betätigen.It is advantageous if the shut-off device has a common shut-off element for each of the two adjacent work stations, which can be controlled in a defined manner by a drive, in particular a stepper motor. The production costs can be further reduced as a result. In principle, however, it would also be possible to provide two separate shut-off elements which are controlled by means of a common drive. The shut-off element can be controlled in a defined manner in a particularly favorable manner by means of a stepping motor, and it can thus be ensured that the shut-off element is actually in the desired position. However, it would also be conceivable to actuate the shut-off element by means of one or preferably several pneumatic cylinders.
Besonders vorteilhaft ist es, wenn das Absperrelement mittels des Antriebs in wenigstens drei verschiedene Stellungen verbringbar ist, wobei das Absperrelement in einer ersten Stellung die Saugdüsen der zwei benachbarten Arbeitsstellen absperrt, in einer zweiten Stellung nur die Saugdüse einer ersten der beiden Arbeitsstellen absperrt und in einer dritten Stellung nur die Saugdüse einer zweiten der beiden Arbeitsstellen absperrt. Die Saugdüse der jeweils anderen Arbeitsstelle bleibt somit an das Unterdrucksystem angeschlossen und kann entsprechend mit Unterdruck beaufschlagt werden. Hierdurch ist es möglich, den Saugdüsen benachbarter Arbeitsstellen Saugluft unabhängig voneinander zu unterschiedlichen Zeitpunkten zur Verfügung zu stellen und dadurch dem zeitlich unterschiedlichen Saugluftbedarf an den beiden Arbeitsstellen Rechnung zu tragen.It is particularly advantageous if the shut-off element can be brought into at least three different positions by means of the drive, with the shut-off element shutting off the suction nozzles of the two adjacent work stations in a first position, only shutting off the suction nozzle of a first of the two work stations in a second position and in one third position only shuts off the suction nozzle of a second of the two work stations. The suction nozzle of the respective other work station thus remains connected to the vacuum system and can be subjected to vacuum accordingly. This makes it possible to make suction air available to the suction nozzles of adjacent work stations independently of one another at different times and thereby to take into account the suction air requirement at the two work stations that differs over time.
Ebenso ist es vorteilhaft, wenn das Absperrelement mittels des Antriebs in wenigstens drei verschiedene Stellungen überführbar ist, wobei das Absperrelement in einer ersten Stellung die Fadenspeicherdüsen der zwei benachbarten Arbeitsstellen absperrt, in einer zweiten Stellung nur die Fadenspeicherdüse einer ersten der beiden Arbeitsstellen absperrt und in einer dritten Stellung nur die Fadenspeicherdüse einer zweiten der beiden Arbeitsstellen absperrt. Die Fadenspeicherdüse der jeweils anderen Arbeitsstelle bleibt wiederum an das Unterdrucksystem angeschlossen und kann bis zum Ende des Ansetzprozesses mit Unterdruck beaufschlagt werden.It is also advantageous if the shut-off element can be moved into at least three different positions by means of the drive, with the shut-off element shutting off the yarn storage nozzles of the two adjacent work stations in a first position, only the yarn storage nozzle of a first of the two work stations blocked in a second position and in one third position only the yarn storage nozzle of a second of the two jobs cordoned off. The thread storage nozzle of the respective other work station remains connected to the vacuum system and can be subjected to vacuum until the end of the piecing process.
Nach einer Weiterbildung der Erfindung ist es zudem vorteilhaft, wenn mittels des Absperrelements ein Ansaugquerschnitt der jeweiligen Saugleitung regulierbar ist. Dies kann beispielsweise dadurch erfolgen, dass das Absperrelement in eine oder mehrere Zwischenstellungen überführbar ist, in welcher oder welchen es den Querschnitt der Saugleitung nur teilweise freigibt. Die Saugluftzufuhr an die jeweilige Saugdüse oder die jeweilige Fadenspeicherdüse kann hierdurch entsprechend dem Bedarf angepasst werden. Ebenfalls vorteilhaft ist es dabei, wenn das Absperrelement stufenlos zwischen der zweiten und der dritten Stellung verfahren werden kann, um den Ansaugquerschnitt entsprechend der jeweiligen Bedürfnisse freizugeben bzw. zu verschließen.According to a development of the invention, it is also advantageous if a suction cross-section of the respective suction line can be regulated by means of the shut-off element. This can be done, for example, by the shut-off element being able to be moved into one or more intermediate positions in which it only partially opens up the cross-section of the suction line. The supply of suction air to the respective suction nozzle or the respective thread storage nozzle can thereby be adjusted according to need. It is also advantageous if the shut-off element can be moved steplessly between the second and the third position in order to open or close the suction cross section according to the respective needs.
Nach einer ersten vorteilhaften Ausführung der Erfindung ist das Absperrelement als Schiebeventil ausgebildet. Im einfachsten Fall beinhaltet das Schiebeventil einen Schieber, der mit wenigstens einer Durchgangsöffnung versehen ist, welche in ihren Querschnitt in etwa einem Querschnitt der jeweiligen Saugleitung entspricht. Mittels eines Antriebs ist der Schieber translatorisch bewegbar. Ein Absperrelement mit einem derartigen Schieber ist besonders einfach und kostengünstig herstellbar. Natürlich ist es dabei je nach Anordnung der Saugleitungen und Verwendungszweck auch möglich, den Schieber mit mehreren Durchgangsöffnungen zu versehen.According to a first advantageous embodiment of the invention, the shut-off element is designed as a sliding valve. In the simplest case, the slide valve includes a slide that is provided with at least one through opening, the cross section of which corresponds approximately to a cross section of the respective suction line. The slide can be moved translationally by means of a drive. A shut-off element with a slide of this type can be produced in a particularly simple and cost-effective manner. Of course, depending on the arrangement of the suction lines and the intended use, it is also possible to provide the slide with several passage openings.
Nach einer anderen Ausführung der Erfindung ist das Absperrelement als Drehventil ausgebildet. Das Drehventil beinhaltet wiederum wenigstens eine Durchgangsöffnung, welche sowohl längs der Drehachse als auch quer zur Drehachse des Drehventils angeordnet sein kann. Auch bei dem Drehventil sind mehrere Durchgangsöffnungen möglich. Ein solches Drehventil kann besonders platzsparend im Inneren einer Saugleitung angeordnet werden.According to another embodiment of the invention, the shut-off element is designed as a rotary valve. The rotary valve in turn contains at least one passage opening, which can be arranged both along the axis of rotation and transversely to the axis of rotation of the rotary valve. Several passage openings are also possible with the rotary valve. Such a rotary valve can be arranged in a particularly space-saving manner inside a suction line.
Weiterhin ist es vorteilhaft, wenn die Absperreinrichtung über eine Steuerleitung an eine Arbeitsstellensteuerung angeschlossen ist. Die Absperreinrichtung kann hierdurch im Zusammenwirken mit anderen Organen der Arbeitsstelle genau dann durch die Arbeitsstellensteuerung betätigt werden, wenn dies im Ansetzprozess erforderlich ist. Vorzugsweise ist dabei die Arbeitsstellensteuerung als Gruppensteuerung für wenigstens zwei Arbeitsstellen, vorzugsweise für vier Arbeitsstellen, ausgebildet. Die Abstimmung der Prozesse an den einzelnen benachbarten Arbeitsstellen ist hierdurch in einfacher Weise möglich.Furthermore, it is advantageous if the shut-off device is connected to a workplace controller via a control line. In this way, the shut-off device can be actuated by the workplace control in cooperation with other organs of the workplace exactly when this is necessary in the piecing process. The workplace control is preferably designed as a group controller for at least two workplaces, preferably for four workplaces. This makes it easy to coordinate the processes at the individual neighboring work stations.
Ebenso ist es vorteilhaft, wenn die Saugleitungen der Saugdüse und der Fadenspeicherdüse in einem Mündungsbereich in eine gemeinsame Anschlussleitung münden, mittels welcher sie mit dem Unterdrucksystem verbunden sind. Der konstruktive Aufbau der Textilmaschine wird hierdurch weiter vereinfacht. Zudem werden auch hierdurch Kostenvorteile erreicht.It is also advantageous if the suction lines of the suction nozzle and the thread storage nozzle open into a common connecting line in an opening area, by means of which they are connected to the vacuum system. This further simplifies the construction of the textile machine. In addition, cost advantages are also achieved as a result.
Besonders vorteilhaft ist es dabei, wenn das Absperrelement in dem Mündungsbereich angeordnet ist. Es kann hierdurch besonders platzsparend untergebracht werden.It is particularly advantageous if the shut-off element is arranged in the mouth area. As a result, it can be accommodated in a particularly space-saving manner.

Zum Aufsuchen eines auf die Spule 6 aufgelaufenen Fadenendes nach einem Fadenbruch oder einem Reinigerschnitt weist jede der Arbeitsstellen 2 weiterhin eine arbeitsstelleneigene Saugdüse 5 auf. In vorliegendem Beispiel ist die Saugdüse 5 fest an der Arbeitsstelle 2 angeordnet und der Faden 8 verläuft während der Produktion durch die Saugdüse 5 hindurch. Ebenso ist es jedoch auch möglich, dass die Saugdüse schwenkbar an der Arbeitsstelle angeordnet ist. Weiterhin weist jede der Arbeitsstellen 2 eine auf den Fadenlauf gerichtete, arbeitsstelleneigene Fadenspeicherdüse 4 zum Aufnehmen eines temporären Fadenüberschusses auf. Derartige temporäre Überlängen des Fadens können während des Ansetzprozesses aufgrund der Arbeitsorgane der Arbeitsstellen 2, insbesondere der Spulvorrichtung 26, entstehen.In order to search for a thread end that has run onto the
Die Saugdüsen 5 und die Fadenspeicherdüsen 4 können über ein Unterdrucksystem 7 der Textilmaschine 1 mit Unterdruck beaufschlagt werden. Das Unterdrucksystem 7 weist wenigstens einen Unterdruckkanal 21 auf, welcher sich entlang der Arbeitsstellen 2 erstreckt und durch eine Unterdruckquelle 22 beaufschlagt wird. Zwischen der Unterdruckquelle 22 und dem Unterdruckkanal 21 ist weiterhin noch ein Filterkasten 23 angeordnet.The
Der Unterdruck wird während des Ansetzprozesses zu unterschiedlichen Zeiten benötigt. Beispielsweise benötigt zunächst nur die Saugdüse 5 Unterdruck, um das Fadenende aufzusuchen, während die Fadenspeicherdüse 4 erst nach dem Auffinden des Fadenendes Unterdruck benötigt. Weiterhin sind auch die Zeitspannen, über welche Unterdruck benötigt wird, unterschiedlich. Die Saugdüse 5 benötigt nur relativ kurzzeitig Unterdruck, während die Fadenspeicherdüse 4 nach dem Auffinden des Fadenendes nahezu über den gesamten Ansetzprozess Saugluft benötigt. Um die Saugdüsen 5 und die Fadenspeicherdüsen 4 in optimaler Weise mit ausreichend Saugluft zur richtigen Zeitpunkt zu versorgen, können die Saugdüsen 5 und die Fadenspeicherdüsen 4 der einzelnen Arbeitsstellen 2 unabhängig voneinander vom Unterdrucksystem getrennt werden, wie nun anhand der
