Description

Technisches GebietTechnical area

Die Erfindung betrifft eine Ringspinnmaschine oder eine Vorspinnmaschine mit einer Vielzahl von Arbeitsstellen und mit einem durch einen Elektromotor entlang der Arbeitsstellen verfahrbaren Wanderreiniger. In weiterer Ausgestaltung der Erfindung ist die Spinnereimaschine darüber hinaus auf jeder Maschinenseite mittels eines durch einen Elektromotor entlang der Arbeitsstellen synchron mit dem Wanderreiniger verfahrbaren Unterwinderestentferner ausgerüstet.The invention relates to a ring spinning machine or a roving machine with a plurality of jobs and with a movable by an electric motor along the work stations hiking cleaner. In a further embodiment of the invention, the spinning machine is also equipped on each side of the machine by means of a movable by an electric motor along the jobs synchronously with the traveling cleaner Unterwinderestentferner.

Stand der TechnikState of the art

Wanderbläser an Ringspinnmaschinen oder an Vorspinnmaschinen haben die Aufgabe, diese Maschinen von abgelagertem Flug und Staub zu befreien und fahren deshalb an diesen Maschinen entlang, wobei sie diese vor allem mit Blasluftstrom beaufschlagen. Es sind aber auch Wanderbläser bekannt, die mit Saugvorrichtungen kombiniert sind.Wanderbläser on ring spinning machines or on roving machines have the task of freeing these machines from deposited flight and dust and therefore drive along these machines, where they act on these mainly with blast air. But there are also known walkers, which are combined with suction devices.

Spinnmaschinen und Wanderreiniger werden in aller Regel von unterschiedlichen Firmen hergestellt und angeboten. Sie sind daher vorteilhafter Weise frei kombinierbar. Jedes der Arbeitsaggregate weist daher eine autarke Steuervorrichtung auf, die die Arbeitsweise eines Wanderreinigers von der oder den Spinnmaschinen, an denen er tätig ist, unabhängig macht. Eine Verbindung besteht nur in soweit, als die beiden Aggregate im Konfliktfalle auf einander Rücksicht nehmen bzw. sich gegenseitig beeinflussen. Als Konfliktfall wirkt bspw. der Spulenwechselvorgang, der bei fortgesetzter Abblastätigkeit gestört werden kann oder die Bedienung von Spinnstellen der Maschinen, die eine Bedienperson behindert.Spinning machines and traveling cleaners are usually produced and offered by different companies. They are therefore advantageously combined freely. Each of the working units therefore has a self-contained control device, which makes the operation of a walking cleaner of the spinning or spinning machines on which it operates independent. A connection exists only in so far as the two aggregates take in case of conflict on each other consideration or influence each other. As a conflict, for example, the bobbin change process that can be disturbed in continued Abblastätigkeit or the operation of spinning stations of the machines, which hinders an operator.

Ein derartiges Zusammenwirken von Ringspinn- oder Vorspinnmaschine und Wanderbläser geht aber über die Berücksichtigung von Konfliktfällen weit hinaus. So könnte die Tätigkeit eines Wanderreinigers wesentlich stärker auf Anforderungen der Spinnereimaschine abgestellt werden: lange Wartezeiten der Maschine, wenn der Wanderbläser vor einem Kopswechselvorgang in seinen Bahnhof fahren soll, Vorausplanen seiner Leerung und dergleichen Bedürfnisse von Maschine und Wanderbläser könnten optimal aufeinander abgestimmt werden, wenn ihre Tätigkeiten stärker miteinander verzahnt werden würden.However, such an interaction of ring spinning or roving machine and Wanderbläser goes far beyond the consideration of conflict cases. Thus, the activity of a walking cleaner could be much more focused on the requirements of the spinning machine: long waiting times of the machine, if the Wanderbläser is to drive before a cop exchange process in his station, anticipating his emptying and the like needs of the machine and Wanderbläser could be optimally matched to each other, if their Activities would be more closely linked.

Besonders vorteilhaft erscheint die Erfindung an Ringspinnmaschinen, die neben einem Wanderreiniger auch einen oder - bei zweiseitigen Ringspinnmaschinen - zwei Unterwinderestentferner aufweisen. Unterwinderestentferner verursachen Faserflug, der durch den Saugzug eines Wanderreinigers gesammelt und entfernt werden sollte. Hierzu müssen sich Unterwinderestentferner und Wanderreiniger synchron zueinander entlang der Ringspinnmaschine bewegen.Particularly advantageous, the invention of ring spinning machines, which in addition to a traveling cleaner also have one or - in two-sided ring spinning machines - two Unterwinderestentferner. Underwear removers cause fiber fly, which should be collected and removed by the suction pull of a hiking cleaner. For this purpose, Unterwinderestentferner and Wanderreiniger must move synchronously to each other along the ring spinning machine.

Aus der DE 41 40 049 C2 ist eine Ringspinnmaschine bekannt, die eine sowohl saugende als auch blasende, über dem Gatter der Ringspinnmaschine entlang der Arbeitsstellen der Ringspinnmaschine verfahrbare Reinigungsvorrichtung in Form eines Wanderreinigers und jeder ihrer beiden Maschinenseiten einen Unterwinderestentferner aufweist, die im Unterwindebereich der Ringspinnspindeln an diesen entlang bewegt werden. Durch den Unterwinderestentferner werden die Unterwindungen von den Spindeln gelöst und mittels einer am Wanderreiniger angeordneten Saugdüse abgesaugt. Um dies zu erreichen, müssen Unterwinderestentferner und Saugdüse des Wanderreinigers derart synchron, sich stets gegenüber stehend bewegt werden, dass gelöste Unterwindungen sogleich in die Saugdüse eingezogen werden, ohne in die Umgebung geschleudert zu werden.From the DE 41 40 049 C2 a ring spinning machine is known, which has both a sucking and blowing, over the gate of the ring spinning machine along the work stations of the ring spinning machine movable cleaning device in the form of a traveling cleaner and each of its two machine sides Unterwinderestentferner which are moved in the underwinding of the ring spinning spindles along this. By Unterwinderestentferner the underwindings are released from the spindles and sucked by means of a suction cleaner arranged on the traveling cleaner. To achieve this, Unterwinderestentferner and suction nozzle of the traveling cleaner must be so synchronously, always moved to face standing, that dissolved underwindings are immediately drawn into the suction nozzle, without being thrown into the environment.

Dieser Synchronlauf wird dadurch erreicht, dass sowohl Wanderreiniger als auch Unterwinderestentferner durch ein einziges, über Umlenkrollen entlang des Gatters und entlang der Spindeln geführtes Zugseil bewegt werden. Dies erfordert bei den vorkommenden großen Maschinenlängen äußerst lange Zugseile und eine komplizierte Zugseilführung. Infolge der Elastizität der langen Zugseile ist auch die exakte Gegenüberstellung von Unterwinderestentferner und Wanderreiniger nicht gegeben.This synchronism is achieved by moving both wiper and under wrench remover through a single pull rope passed over pulleys along the creel and along the spindles. This requires extremely long traction cables and a complicated traction cable guide at the occurring large machine lengths. Due to the elasticity of the long pull ropes and the exact comparison of Unterwinderestentferner and Wanderreiniger is not given.

Daher wurde in der DE 42 31 737 A1 eine elektronische Gleichlaufsteuerung vorgeschlagen, bei der die Laufantriebe von Wanderreiniger und Unterwinderestentferner über eine gemeinsame Steuervorrichtung angesteuert werden. Es ist also eine gemeinsame, aber neben den individuellen Steuervorrichtungen von Wanderreiniger und Ringspinnmaschine erforderliche dritte Steuervorrichtung für die Zusatzaggregate einer Ringspinnmaschine erforderlich.Therefore, in the DE 42 31 737 A1 proposed an electronic synchronization control in which the running drives of Wanderreiniger and Unterwinderestentferner are controlled by a common control device. So it is a common, but required in addition to the individual control devices of hiking cleaner and ring spinning machine third control device for the additional units of a ring spinning machine required.

Allgemeine Beschreibung der ErfindungGeneral description of the invention

Der Erfindung war daher die Aufgabe gestellt, ein engeres Zusammenwirken der unterschiedlichen Spinnereimaschinen und des Wanderreinigers zu erreichen. Sie löst diese Aufgabe dadurch, dass die bisher autonome Tätigkeitssteuerung des Wanderreinigers in die Tätigkeitssteuerung der Spinnereimaschine integriert wird. Die Steuervorrichtung der Spinnereimaschine selbst steuert demnach auch die Tätigkeit des Wanderreinigers, was durch die eine einzige Steuervorrichtung optimaler erfolgen kann als durch gesonderte Steuervorrichtungen. Damit wird auch der Vorteil erreicht, dass am Wanderreiniger eine Steuervorrichtung entfällt.The invention was therefore the task of achieving a closer interaction of the different spinning machines and the traveling cleaner. It solves this task by integrating the hitherto autonomous activity control of the walking cleaner into the activity control of the spinning machine. Accordingly, the control device of the spinning machine itself also controls the activity of the traveling cleaner, which can be done more optimally by a single control device than by separate control devices. Thus, the advantage is achieved that the traveling cleaner eliminates a control device.

Besonders vorteilhaft erscheint die Erfindung an Ringspinnmaschinen, die neben einem Wanderreiniger auch einen oder - bei zweiseitigen Ringspinnmaschinen - zwei Unterwinderestentferner aufweisen. Unterwinderestentferner verursachen in aller Regel Faserflug, der durch den Saugzug eines Wanderreinigers gesammelt und entfernt werden sollte. Hierzu müssen sich Unterwinderestentferner und Wanderreiniger synchron zueinander entlang der Ringspinnmaschine bewegen.Particularly advantageous, the invention of ring spinning machines, which in addition to a traveling cleaner also have one or - in two-sided ring spinning machines - two Unterwinderestentferner. Under-winder removers usually cause fiber fly, which should be collected and removed by the induced draft of a hiking cleaner. For this purpose, Unterwinderestentferner and Wanderreiniger must move synchronously to each other along the ring spinning machine.

Die Steuervorrichtung der Maschine übernimmt also auch das Steuern des Wanderreinigers nach den Bedürfnissen der Ringspinnmaschine bzw. der Vorspinnmaschine. Dies führt zu einer sowohl gerätetechnischen als auch steuerungstechnischen Vereinfachung. Der Wanderreiniger ist zu diesem Zweck mit mindestens einem Sensor ausgerüstet, der seine Beaufschlagung an die Steuervorrichtung der Maschine meldet, die daraus die zweckmäßigen Folgerungen für das Steuern des Wanderreinigers und/oder der Maschine zieht.The control device of the machine thus also takes over the control of the traveling cleaner according to the needs of the ring spinning machine or the roving machine. This leads to both device technology and control technology simplification. The traveling cleaner is equipped for this purpose with at least one sensor, which reports its application to the control device of the machine, which draws therefrom the appropriate conclusions for the control of the traveling cleaner and / or the machine.

Der Sensor kann bspw. ein Berührungssensor sein, der eine im Bewegungsweg des Wanderreinigers stehende Person erkennt. Die Steuervorrichtung der Maschine wird dann entscheiden, ob der Wanderreiniger stehen bleibt und wartet, bis die Person sich entfernt hat oder ob er seine Bewegungsrichtung umkehrt. Oder zum Vorbereiten eines Kopswechselvorganges, dessen herannahender Zeitpunkt der Steuervorrichtung der Maschine bekannt ist, wird sie den Wanderreiniger so rechtzeitig aus dem Spindelbereich zu bewegen beginnen, dass er das Einleiten des Kopswechselvorganges nicht behindern wird.The sensor may, for example, be a touch sensor which recognizes a person standing in the path of movement of the traveling cleaner. The controller of the machine will then decide if the traveling cleaner stops and waits for the person to move away or reverse his direction of movement. Or, to prepare a cop exchange operation whose approaching timing is known to the control device of the machine, it will begin to move the traveling cleaner out of the spindle area in time to prevent it from hindering the initiation of the cop exchange operation.

Insbesondere dann, wenn die Ringspinnmaschine schon die Steuerung der in sie integrierten Unterwinderestentferner inne hat, kann im Blick auf den erforderlichen paarweisen, parallelen Gleichlauf der beiden bzw. der drei Reinigungsvorrichtungen durch diese Integration eine weitere, wesentliche Vereinfachung sowohl in gerätetechnischer als auch steuerungstechnischer Hinsicht erreicht werden.In particular, when the ring spinning machine already has the control of the integrated Unterwinderestentferner in them, can in view of the required pairwise, parallel Synchronization of the two or the three cleaning devices are achieved by this integration a further, substantial simplification both in terms of device technology and control technology.

Um den Wanderreiniger optimal steuern zu können, muss der Steuervorrichtung der Maschine der jeweilige Ort des Wanderreinigers bekannt sein. Hierzu kann der Wanderreiniger mit einem Absolutwertgeber ausgestattet sein, der den seiner Stellung entlang der Maschine entsprechenden Messwert an die Steuervorrichtung der Maschine meldet. Es versteht sich, dass hierfür auch andere Sensoren einsetzbar sind, bspw. Inkrementalgeber.In order to be able to optimally control the traveling cleaner, the control device of the machine must be aware of the respective location of the traveling cleaner. For this purpose, the traveling cleaner can be equipped with an absolute value transmitter, which reports the measured value corresponding to its position along the machine to the control device of the machine. It goes without saying that other sensors can also be used for this purpose, for example incremental encoders.

In vielen Fällen ist es jedoch auch ausreichend, an den Enden der Bewegungswege von Wanderreiniger und Unterwinderestentferner Sensoren vorzusehen, die den Einlauf der Reinigungsgeräte an diesen Endstellungen melden. Die Stellungen der Reinigungsgeräte kann dann neutralisiert werden, so dass sie wieder zugleich von gleichen Grundstellungen aus zu laufen beginnen.In many cases, however, it is also sufficient to provide at the ends of the movement paths of traveling cleaner and Unterwinderestentferner sensors that report the inlet of the cleaning equipment at these end positions. The positions of the cleaning devices can then be neutralized so that they start to run again from the same basic positions.

Weitere vorteilhafte Ausgestaltungen ergeben sich aus den Unteransprüchen.Further advantageous embodiments will be apparent from the dependent claims.

  • Fig. 1 die Seitenansicht wesentlicher Arbeitsorgane einer Ringspinnmaschine;
  • Fig. 2 rein schematisch eine Variante der in Fig. 1 dargestellten Ringspinnmaschine;

  • Fig. 1 the side view of essential work organs of a ring spinning machine;
  • Fig. 2 purely schematically a variant of in Fig. 1 illustrated ring spinning machine;
  • Fig. 3 another variant of in Fig. 1 illustrated embodiment.

Wenn im Folgenden von einer Ringspinnmaschine gesprochen wird, versteht es sich, dass es sich dabei auch um eine Vorspinnmaschine handeln kann. Die Beschreibung der Steuerung eines Unterwinderestentferners trifft selbstverständlich auf eine Vorspinnmaschine nicht zu.When it is spoken in the following of a ring spinning machine, it is understood that it may also be a roving. The description of the control of a Unterwinderestentferners of course does not apply to a roving.

Die Ringspinnmaschine weist ein Anfangsgestell 1 und ein Endgestell 2 auf, zwischen denen sich im Wesentlichen ein Gatter 3, sowie beiderseits Streckwerke 4 und Spindelbänke 5 erstrecken. Die eine hier dargestellte Spindelbank enthält eine Vielzahl von Spindeln, die hier nur durch ihre Mittellinien 6 angedeutet sind. Die Ringspinnmaschine weist darüber hinaus hier nicht wiedergegebene Arbeitsorgane wie Ringbänke und dergleichen und Zusatzaggregate wie eine Kopswechselvorrichtung auf. Ferner ist die Ringspinnmaschine mit einer Steuervorrichtung 7 versehen, über deren Ausgänge 8 ihre Arbeits- und Zusatzaggregate funktionsgerecht steuerbar sind. Es versteht sich, dass eine geläufige Ringspinnmaschine zweiseitig ausgeführt ist, sie also auf beiden Maschinenseiten Streckwerke und Spindelbänke aufweist.The ring spinning machine has an initial frame 1 and a terminal frame 2, between which substantially a gate 3, as well as drafting units 4 and spindle banks 5 extend on both sides. The spindle bank shown here contains a plurality of spindles, which are indicated here only by their center lines 6. The ring spinning machine also has here not reproduced working organs such as ring banks and the like and Additional units such as a Kopswechselvorrichtung on. Furthermore, the ring spinning machine is provided with a control device 7, through whose outputs 8 their working and additional units are functionally controllable. It is understood that a common ring spinning machine is designed on two sides, so it has drafting and spindle banks on both sides of the machine.

Die Ringspinnmaschine ist auch mit einem Wanderreiniger 9 ausgestattet, der die Maschine von Flug und Staub frei hält. Er ist oberhalb des Gatters 3 mittels Spurrollen 10 auf Schienen 11 verfahrbar, die sich längs der Ringspinnmaschine erstrecken. Er enthält einen motorgetriebenen Blasluftventilator und weist zwei Blasschläuche 12 auf, die sich auf beiden Seiten der Ringspinnmaschine nach unten erstrecken und mit dem Blasluftstrom des Blasluftventilators die Aggregate der Ringspinnmaschine bestreichen. Die Bewegung des Wanderreinigers 9 entlang der Ringspinnmaschine erfolgt durch den Antrieb mindestens einer seiner Spurrollen 10 durch einen Antriebsmotor 13.The ring spinning machine is also equipped with a traveling cleaner 9, which keeps the machine free of air and dust. It is above the gate 3 by means of track rollers 10 on rails 11 movable, which extend along the ring spinning machine. It contains a motor-driven blast air fan and has two blast hoses 12, which extend down on both sides of the ring spinning machine and coat the aggregates of the ring spinning machine with the blast air flow of the blast air fan. The movement of the traveling cleaner 9 along the ring spinning machine takes place by the drive of at least one of its track rollers 10 by a drive motor 13.

Der Wanderreiniger enthält weitere Aggregate wie einen Berührungssensor 14, der die Annäherung an ein Hindernis oder das Erreichen eines Endpunktes seines Bewegungsweges fühlt. Häufig ist der Wanderreiniger auch mit einer Saugvorrichtung ausgestattet, durch die mittels eines Saugschuhs 15 Flug und Staub etwa vom Boden aufgesaugt wird. In diesem Falle kann in den Blasschlauch 12 ein Saugschlauch eingebettet sein, der mit dem Saugluftstrom des Blasluftventilators beaufschlagt wird. Dieser Abfall wird im Wanderreiniger in einem Speicher gesammelt. Der Speicher weist einen Sensor auf, der das Vollwerden des Speichers fühlt und dessen Entleerung in einen ortsfesten Abfallsammler 16 veranlasst.The traveling cleaner contains other aggregates, such as a touch sensor 14, which feels approaching an obstacle or reaching an endpoint of its travel. Frequently, the traveling cleaner is also equipped with a suction device, by means of a suction shoe 15 flight and dust is sucked up from the ground. In this case, a suction hose can be embedded in the blast hose 12, which is acted upon by the suction air flow of the blast air fan. This waste is collected in the hiking cleaner in a store. The memory has a sensor which senses the saturation of the reservoir and causes its emptying into a stationary waste collector 16.

Die Signale der Sensoren wie 14 des Wanderreinigers 9 werden über eine mehradrige oder busbelegte Leitung 17 der Steuervorrichtung 7 der Ringspinnmaschine zugeleitet. Dort werden auch sie funktionsgerecht verarbeitet und auch andere funktionsgerechte Steuersignale für den Wanderreiniger generiert. Sie werden dann als Steuersignale über eine Leitung 17 wieder dem Wanderreinigers zugeleitet. Die Steuerung der Funktionen des Wanderreinigers 9 ist also in die Steuervorrichtung 7 der Ringspinnmaschine integriert, so dass der Wanderreiniger keine eigene Steuervorrichtung aufweisen muss. Er ist über eine Schnittstelle 19 mit der Steuervorrichtung 7 der Ringspinnmaschine verbunden, in der gegebenenfalls die Steuersignale der Steuervorrichtung in dem Wanderreiniger verständliche Steuersignale umgesetzt werden. Diese Schnittstelle kann in die Steuervorrichtung 7 der Ringspinnmaschine oder in den Wanderreiniger 9 integriert sein. Die Steuerungskapazität und die Steuerungsintelligenz der Steuervorrichtung 7 der Ringspinnmaschine ist so ausgelegt, dass sie diese zusätzlichen Steuerfunktionen für den Wanderreiniger ohne weiteres mit übernehmen kann.The signals of the sensors such as 14 of the traveling cleaner 9 are fed via a multi-wire or bus-covered line 17 of the control device 7 of the ring spinning machine. There, they are processed functionally and also generated other functional control signals for the Wanderreiniger. They are then forwarded as control signals via a line 17 back to the hiking cleaner. The control of the functions of the traveling cleaner 9 is thus integrated into the control device 7 of the ring spinning machine, so that the traveling cleaner does not have to have its own control device. It is connected via an interface 19 with the control device 7 of the ring spinning machine, in which optionally the control signals of the control device in the traveling cleaner understandable control signals be implemented. This interface can be integrated in the control device 7 of the ring spinning machine or in the traveling cleaner 9. The control capacity and the control intelligence of the control device 7 of the ring spinning machine is designed so that it can easily take over these additional control functions for the traveling cleaner.

In weiterer Ausgestaltung ist die Ringspinnmaschine gemäß den Figuren 2 und 3 mit einer Einrichtung zum Entfernen von Unterwindungen von den Ringspinnspindeln 6 ausgerüstet. Diese weisen zu diesem Zweck unterhalb eines jeden Kopses 20, von denen in den Figuren 2 und 3 nur einer dargestellt ist, einen Unterwindebereich 21 auf, auf den zum Spulenwechsel einige Fadenwindungen aufgebracht werden, von denen aus die Bewicklung der neu aufgesteckten Hülsen starten kann. Diese Unterwindungen müssen von Zeit zu Zeit entfernt werden. Dazu dient auf jeder Maschinenseite je ein Unterwinderestentferner 22, der an einem endlosen Zugband 23 befestigt ist, mittels dessen er in Höhe der Unterwindebereiche 21 entlang der Reihe der Ringspinnspindeln 6 bewegt wird. Die Zugbänder ist an beiden Enden der Spindelbänke 5 über je eine Umlenkrolle 24 und je eine Leitrolle 25 geführt, wobei je eine der Umlenkrollen mit einem Antriebsmotor 26 versehen ist.In a further embodiment, the ring spinning machine according to the FIGS. 2 and 3 equipped with a device for removing underwindings of the ring spinning spindles 6. These have for this purpose below each cop 20, of which in the FIGS. 2 and 3 only one is shown, an underwinding area 21, are applied to the bobbin change a few turns of thread, from which the winding of the newly plugged sleeves can start. These shortcomings must be removed from time to time. For this purpose, on each side of the machine a Unterwinderestentferner 22 which is attached to an endless drawstring 23, by means of which it is moved in the amount of Unterwindebereiche 21 along the row of Ringspin spindles 6. The drawstrings is guided at both ends of the spindle banks 5 via a respective deflection roller 24 and a respective guide roller 25, wherein each one of the deflection rollers is provided with a drive motor 26.

Die Unterwinderestentferner 22 sind mit scharfe Zähne aufweisenden Garnituren versehen, mittels deren die Unterwindungen aufgerissen werden, die dann durch die Zentrifugalbeschleunigung der rasch laufenden Ringspinnspindeln von diesen abgeschleudert werden. Diese abgeschleuderten Unterwindereste müssen entsorgt werden, wozu der Wanderreiniger 9 herangezogen wird. Der Saugzug seines Saugventilators wird hierzu über zwei Saugschläuche 27 zu den beiden Unterwinderestentfernern geleitet, wo sie in zwei Saugöffnungen 28 münden. Hierbei muss sichergestellt sein, dass diese Sauöffnungen 28 stets den Unterwinderestentfernern 22 gegenüber stehen.The under-wrench removers 22 are provided with sharp-toothed sets, by means of which the underwindings are torn open, which are then thrown off from them by the centrifugal acceleration of the rapidly moving ring spinning spindles. These thrown-off underwear must be disposed of, what the Wanderreiniger 9 is used. The induced draft of its suction fan is for this purpose passed over two suction hoses 27 to the two Unterwinderestentfernern, where they open into two suction openings 28. In this case, it must be ensured that these suction openings 28 are always opposite the underwinding remover 22.

Um dies zu erreichen, kann in einer ersten Ausführungsform der Erfindung gemäß Figur 2 die Stellung der drei wandernden Arbeitsorgane Unterwinderestentferner 22 und Wanderreiniger 9 jeweils am Ende ihres Bewegungsweges neutralisiert, d.h. Gleichstellung herbei gerührt werden und beim Rücklauf wieder von dieser Gleichstellung ausgegangen werden. Zu diesem Zweck ist die Steuervorrichtung 7 der Ringspinnmaschine derart programmiert, dass sie die drei Reinigungsvorrichtungen 9 und 22 in ihre Endstellungen laufen lässt und deren Rücklauf erst einleitet, nachdem alle diese Endstellungen erreicht haben. Das Erreichen der Endstellungen kann dadurch sichergestellt werden, dass der Rücklauf der wandernden Arbeitsorgane so lange verzögert wird, bis damit gerechnet werden kann, dass sie alle ihre Endstellungen erreicht haben.In order to achieve this, in a first embodiment of the invention according to FIG. 2 neutralizes the position of the three migrating working organs Unterwinderestentferner 22 and Wanderreiniger 9 each at the end of their movement, ie equality be stirred herbei and are expected in the return of this equality again. For this purpose, the control device 7 of the ring spinning machine is programmed so that it can run the three cleaning devices 9 and 22 in their end positions and initiates the return only after all of these end positions have been reached. Reaching the End positions can be ensured by delaying the return of the migrating bodies of work until it can be expected that they have reached their final positions.

Alternativ kann vorgesehen sein, an den Endstellungen von Wanderreiniger 9 und Unterwinderestentfernern 22 Sensoren 29 bzw. 30 anzuordnen, die das Einlaufen jedes der wandernden Arbeitsorgane fühlt und über eine Signalleitung 17 an die Steuervorrichtung 7 der Ringspinnmaschine meldet. Diese leitet den Rücklauf ein, wenn von allen drei Sensoren an einem Ende der Bewegungswege Einlaufsignale vorliegen.Alternatively it can be provided to arrange at the end positions of Wanderreiniger 9 and Unterwinderestentfernern 22 sensors 29 and 30, which feels the running of each of the migrating working organs and reports via a signal line 17 to the control device 7 of the ring spinning machine. This initiates the return if there are run-in signals from all three sensors at one end of the travel paths.

Bevorzugt ist aber vorgesehen, je eine der Umlenkrollen 24 jedes der beiden Zugbänder 23 und eine der Spurrollen 10 des Wanderreinigers 9 mit einem Inkrementalgeber 31 bzw. 32 zu versehen, der die Drehbewegung der Leitrolle bzw. der Spurrolle abgreift. Die Inkrementalgeber 31, 32 können eine Inkrementscheibe 33 und einen Inkrementalsensor 34 aufweisen und ihr Signal und über eine Signalleitung 17 der Steuervorrichtung 7 der Ringspinnmaschine zuführen.However, it is preferably provided to provide one of the deflection rollers 24 of each of the two drawstrings 23 and one of the track rollers 10 of the traveling cleaner 9 with an incremental encoder 31 or 32, which picks up the rotational movement of the guide roller or track roller. The incremental encoders 31, 32 may have an incremental disk 33 and an incremental sensor 34 and supply their signal and via a signal line 17 to the control device 7 of the ring spinning machine.

In der Steuervorrichtung 7 der Ringspinnmaschine werden die von den drei Inkrementalgebern 31 und 32 eingehenden Inkrementschritte verglichen und bei Vorlauf eines der wandernden Arbeitsorgane Wanderreiniger 9 oder Unterwinderestentferner 22 die Beaufschlagung von dessen Antriebsmotor 13 oder 26 mit Antriebsenergie gedrosselt bzw. bei Nachlauf erhöht, um den parallelen Gleichlauf wieder herzustellen. Wenn die Antriebsmotoren als Synchronmotoren ausgeführt sind, ist deren Speisefrequenz entsprechend zu verändern. Sie wird den Antriebsmotoren über Signalleitungen 18 zugeführt.In the control device 7 of the ring spinning machine incoming from the three incremental encoders 31 and 32 increment steps are compared and in advance of one of the migrating working elements Wanderreiniger 9 or Unterwinderestentferner 22 throttling the supply of the drive motor 13 or 26 with drive energy or increases in caster to the parallel To restore synchronization. If the drive motors are designed as synchronous motors, their supply frequency must be changed accordingly. It is supplied to the drive motors via signal lines 18.
