Definitions
- the invention relates to a method for operating an open-end rotor spinning machine with a plurality of similar jobs, each having an open-end spinning device for producing a thread and a winding device for producing a cross-wound bobbin and a single driven device for preparing a required for re-spinning thread end, said the winding device includes a pivotally mounted creel, a powered by a reversible single drive drive drum and a motor driven Einzelchang Fadenchangier alike and the jobs are each equipped with a pivotally mounted suction nozzle.
- Open-end rotor spinning machines have long been known and usually consist of a plurality of juxtaposed in series, similar jobs. Each of these jobs has both a spinning and a winding device, where the sliver presented in a sliver can be spun into a yarn and wound into a cheese.
- the presented sliver is fed by means of a sliver feed cylinder of the opening roller, which dissolves the sliver in individual fibers with their clothing and transported to the fiber channel of the spin box.
- the fiber transport is supported by the negative pressure in the rotor housing, which generates an air flow in the fiber channel, releases the fibers from the dissolving set and conveys them into the rotor via the so-called channel plate adapter. Due to the centrifugal force, the fibers slip into the collecting groove of the rotor, where they are collected according to the set yarn count, drawn off through the draw-off nozzle in the axis of rotation and thus twisted into a yarn and wound up.
- the spinning or winding devices are each in communication with a workstation computer.
- the individual workstation computers are in turn optionally connected via section control units to the central control unit of the open-end rotor spinning machine.
- a method for optimizing a lot change on an open-end spinning machine is the DE 196 48 215 A1 removable.
- a bobbin exchange strategy is disclosed .
- the time of the end of the game is advanced so that the period is eliminated in which the efficiency drops so seriously that the resulting losses exceed the value difference between in this time still producible ready-wound cheeses and packages 2nd choice. Therefore, the period of time between the initiation of the end of the lot and the end of the lot must be at least equal to the production time necessary to reach a 2nd choice package. If the time period mentioned is below this mecanicbewicklungsdauer, the spinning unit is stopped.
- a disadvantage of the method proves that due to the central drives to perform the lot change the entire open-end spinning machine or at least sections must be shut down so that the required work can be performed by the operator and the maintenance facility. These time-consuming tasks reduce the efficiency of the open-end spinning machine, because during this work, the respective jobs over a longer period of time can produce no yarn.
- a disadvantage of the method according to the prior art proves that usually a lot change also requires the replacement of the fiber raw material and the spin agent. Only in exceptional cases, these factors of different games match, so that in the described circumstances can not really be spoken of a game change.
- the invention has for its object to propose a method that allows a smooth batch change including the exchange of the fiber raw material and spin agents.
- a required step for the batch start which is carried out automatically by the work station, the retrieval of stored game data to the central computer.
- the basic settings of earlier games are stored and can be retrieved independently from the respective job, so that they serve as the basis for the current game.
- the claims 4 and 5 illustrate that operations to be performed by the operator are the replacement of the spinning can and / or the replacement of spinning means.
- operations to be performed by the operator are the replacement of the spinning can and / or the replacement of spinning means.
- spin agent such as the rotor or the discharge nozzle
- FIG. 1 schematically shows a front view of an open-end rotor spinning machine 40 with end frames 41, 42 and a plurality between the end frames 41, 42 arranged similar, self-sufficient work places.
- end frames 41 and 42 as usual, for example, a textile machine's own vacuum source 45, an electrical power supply and a central computer 46 of the open-end rotor spinning machine 40 are arranged.
- the central computer 46 is in turn connected to the workstation computers 47 of the individual workstations 1, preferably via a bus system 43.
- the numerous work stations 1 each have a workstation housing 11 with an open-end spinning device 2, a winding device 44, a suction nozzle 4 and other known yarn treatment devices, such as a waxing device 5, on.
- a sliver 48 which is stored in sliver cans 49, which are positioned in series next to each other below the work stations 1, spun into a yarn 3, which then on the winding device 44 to a cheese 8 is wound up.
- the open-end rotor spinning machine 40 is also equipped with a movable along the workstations 1 cheese package changer 6, which changes in case of need finished cheeses 8 against fresh empty tubes 10.
- FIG. 2 shows in front view and on a larger scale one of the self-sufficient jobs 1 of the open-end rotor spinning machine 40 during the spinning process. That is, in the open-end spinning device 2, a sliver 48 fed via the sliver feed roller 25 is spun into a finished yarn 3 which is drawn off by the yarn take-off device 35.
- the finished thread 3 is tangent on its way to the cheese 8, the piecing element 20, the thread cleaner 21, the thread tensioner 16 and the waxing device 5, before he traverses, traversed by the Fadenchangier responded 18, runs on the cheese 8.
- the cross-wound bobbin 8 is held freely rotatably in a creel 9 and is acted upon rotationally by a drive drum 12 driven by a single motor.
- the suction nozzle 4 of the workstation 1 is defined by means of its stepping motor 28 between a thread receiving position in which the mouth of the suction nozzle 4 is positioned in the region of the cross-wound bobbin 8 held in the creel 9, a yarn transfer position in the region of the spinning device 2 and a rest position 29.
- the suction nozzle 4 is positioned in the rest position 29 during the spinning process and is thereby reliably fixed by a locking device 30.
- the operator can now replace the spinning can 49 together with the sliver 48, use another rotor, not shown, and optionally replace other spin agents such as the trigger nozzle, not shown.
- the operator activates by pressing an operating button 52, the job 1, so that it is released for the other, to be carried out by her self-sufficient work.
- Job 1 retrieves the lot data of the new production at the central computer 46.
- Necessary spinning parameters are, for example, the delay, the yarn twist and the rotor speed.
- These basic game data are transmitted via the bus system 43 to the workstation's own computer 47 and used by them to control the responsible functional elements of the jobs 1.
- the jobs 1 of the open-end spinning machines 40 can complete the cheeses 8 gradually and start after completion of the work necessary for the batch change with the production of the new lot, without having to wait for the remaining jobs 1, the still produce "old" yarn section.

Abstract
Description
Die Erfindung betrifft ein Verfahren zum Betreiben einer Offenend-Rotorspinnmaschine mit einer Vielzahl gleichartiger Arbeitsstellen, die jeweils eine Offenend-Spinnvorrichtung zur Fertigung eines Fadens sowie eine Spulvorrichtung zur Herstellung einer Kreuzspule als auch eine einzeln angetriebene Einrichtung zum Vorbereiten eines zum Wiederanspinnen benötigten Fadenendes aufweisen, wobei die Spulvorrichtung einen schwenkbar gelagerten Spulenrahmen, eine durch einen reversiblen Einzelantrieb beaufschlagbare Antriebstrommel sowie eine einzelmotorisch antreibbare Fadenchangiereinrichtung beinhaltet und die Arbeitsstellen jeweils mit einer schwenkbar gelagerten Saugdüse ausgestattet sind.The invention relates to a method for operating an open-end rotor spinning machine with a plurality of similar jobs, each having an open-end spinning device for producing a thread and a winding device for producing a cross-wound bobbin and a single driven device for preparing a required for re-spinning thread end, said the winding device includes a pivotally mounted creel, a powered by a reversible single drive drive drum and a motor driven Einzelchang Fadenchangiereinrichtung and the jobs are each equipped with a pivotally mounted suction nozzle.
Offenend-Rotorspinnmaschinen sind seit langem bekannt und bestehen in der Regel aus einer Vielzahl von in Reihe nebeneinander angeordneten, gleichartigen Arbeitsstellen. Jede dieser Arbeitsstellen verfügt sowohl über eine Spinn- als auch eine Spulvorrichtung, an denen das in einer Spinnkanne vorgelegte Faserband zu einem Garn versponnen und zu einer Kreuzspule aufgewickelt wird.Open-end rotor spinning machines have long been known and usually consist of a plurality of juxtaposed in series, similar jobs. Each of these jobs has both a spinning and a winding device, where the sliver presented in a sliver can be spun into a yarn and wound into a cheese.
Dazu wird das vorgelegte Faserband mittels eines Faserbandeinzugszylinders der Auflösewalze zugeführt, die mit ihrer Garnitur das Faserband in Einzelfasern auflöst und zum Faserkanal der Spinnbox transportiert. Unterstützt wird der Fasertransport durch den im Rotorgehäuse bestehenden Unterdruck, der im Faserkanal einen Luftstrom erzeugt, die Fasern aus der Auflösegarnitur löst und über den so genannten Kanalplattenadapter gezielt in den Rotor befördert. Durch die Zentrifugalkraft rutschen die Fasern in die Sammelnut des Rotors, werden dort entsprechend der eingestellten Garnfeinheit gesammelt, durch die Abzugsdüse hindurch in der Drehachse abgezogen und so zu einem Garn verdreht und aufgewickelt.For this purpose, the presented sliver is fed by means of a sliver feed cylinder of the opening roller, which dissolves the sliver in individual fibers with their clothing and transported to the fiber channel of the spin box. The fiber transport is supported by the negative pressure in the rotor housing, which generates an air flow in the fiber channel, releases the fibers from the dissolving set and conveys them into the rotor via the so-called channel plate adapter. Due to the centrifugal force, the fibers slip into the collecting groove of the rotor, where they are collected according to the set yarn count, drawn off through the draw-off nozzle in the axis of rotation and thus twisted into a yarn and wound up.
Die Spinn- respektive Spulvorrichtungen stehen jeweils mit einem Arbeitsstellenrechner in Verbindung. Die einzelnen Arbeitsstellenrechner sind ihrerseits gegebenenfalls über Sektionssteuereinheiten an die Zentralsteuereinheit der Offenend-Rotorspinnmaschine angeschlossen.The spinning or winding devices are each in communication with a workstation computer. The individual workstation computers are in turn optionally connected via section control units to the central control unit of the open-end rotor spinning machine.
Um bei einer Offenend-Rotorspinnmaschine eine hohe Produktivität zu erlangen, wird bekanntlich mit möglichst hoher Geschwindigkeit gesponnen respektive aufgewickelt.In order to obtain a high productivity in an open-end rotor spinning machine, it is known that spun respectively wound with the highest possible speed.
Bei einem Partiewechsel werden üblicherweise sowohl der in den Spinnkannen vorgelegte Faserrohstoff einer "alten" Garnpartie, die zugehörigen Kreuzspulen als auch die Spinnmittel wie beispielsweise der Rotor aus den Arbeitsstellen der Offenend-Rotorspinnmaschine entfernt und durch Spinnkannen mit Faserrohstoff einer "neuen" Garnpartie, neue Leerhülsen sowie neue Spinnmittel ersetzt.In a batch change usually both presented in the spinning cans pulp of an "old" yarn lot, the associated cheeses and the spin agents such as the rotor from the work stations of the open-end rotor spinning machine and by spinning cans with pulp of a "new" yarn lot, new empty tubes as well as new spin agents replaced.
Um die Ausfallzeiten der Arbeitsstellen und die damit einhergehenden Produktionsverluste so gering wie möglich zu halten, wurden in der Vergangenheit unterschiedliche Strategien verfolgt.In order to minimize the downtime of jobs and the associated production losses, different strategies have been used in the past.
Ein Verfahren zur Optimierung eines Partiewechsels an einer Offenend-Spinnmaschine ist der
Durch die Offenlegungsschrift
Eine weitere Strategie anfallende Wartungstätigkeiten, insbesondere bei einem Partiewechsel, an einer Offenend-Rotorspinnmaschine in besonders kurzer Zeit durchzuführen, wird durch die
Als nachteilig an den Verfahren erweist sich, dass aufgrund der zentralen Antriebe zur Durchführung des Partiewechsels die gesamte Offenend-Spinnmaschine oder zumindest Sektionen stillgesetzt werden müssen, damit die erforderlichen Arbeiten von dem Bedienpersonal und der Wartungseinrichtung durchgeführt werden können. Diese zeitintensiven Arbeiten vermindern den Wirkungsgrad der Offenend-Spinnmaschine, denn während dieser Arbeiten können die jeweiligen Arbeitsstellen über einen längeren Zeitraum kein Garn produzieren.A disadvantage of the method proves that due to the central drives to perform the lot change the entire open-end spinning machine or at least sections must be shut down so that the required work can be performed by the operator and the maintenance facility. These time-consuming tasks reduce the efficiency of the open-end spinning machine, because during this work, the respective jobs over a longer period of time can produce no yarn.
Aufgrund der
In der entsprechenden Bedienungsanleitung zu einer Offenend-Spinnmaschine mit autarken Arbeitsstellen von Oerlikon Schlafhorst, V3.0 von 12.2011 ist ein so genannter "Gleitender Partiewechsel" beschrieben. Voraussetzung für den gleitenden Partiewechsel ist allerdings, dass sowohl Spinnmittel als auch der Faserrohstoff beider Partien übereinstimmen.In the corresponding user manual for an open-end spinning machine with self-sufficient workstations of Oerlikon Schlafhorst, V3.0 of 12.2011 a so-called "sliding lot change" is described. However, the precondition for the sliding batch change is that both spin agent and the fiber raw material of both lots match.
Arbeitsstellen, die das gleiche Garn herstellen, werden in der Praxis gruppenweise zusammengefasst und als Produktionsgruppe bezeichnet. Bei diesem so genannten gleitenden Partiewechsel stellen alle Arbeitsstellen der entsprechenden Produktionsgruppe nach und nach ihre Kreuzspulen fertig. Nach dem Austausch der fertiggestellten Kreuzspule gegen eine Leerhülse wechselt die Arbeitsstelle in die neue Produktionsgruppe und produziert das Garn der anderen Partie.Workplaces producing the same yarn are grouped together in practice and referred to as a production group. During this so-called sliding batch change, all workstations of the corresponding production group gradually finish their cross-wound bobbins. After replacing the finished cheese with an empty tube, the workplace changes to the new production group and produces the yarn of the other batch.
Nachteilig an dem Verfahren gemäß dem Stand der Technik erweist sich, dass üblicherweise ein Partiewechsel auch das Austauschen des Faserrohstoffes und der Spinnmittel erfordert. Nur in Ausnahmefällen stimmen diese Faktoren verschiedener Partien überein, so dass in dem beschriebenen Sachverhalt nicht wirklich von einem Partiewechsel gesprochen werden kann.A disadvantage of the method according to the prior art proves that usually a lot change also requires the replacement of the fiber raw material and the spin agent. Only in exceptional cases, these factors of different games match, so that in the described circumstances can not really be spoken of a game change.
Ausgehend von Arbeitsstellen der vorgenannten Gattung liegt der Erfindung die Aufgabe zugrunde, ein Verfahren vorzuschlagen, das einen fließenden Partiewechsel inklusive des Austauschs des Faserrohstoffs sowie von Spinnmitteln ermöglicht.Based on jobs of the aforementioned type, the invention has for its object to propose a method that allows a smooth batch change including the exchange of the fiber raw material and spin agents.
Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruches 1 gelöst.This object is achieved by the characterizing features of
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.
Zur Lösung der Aufgabe ist gemäß Anspruch 1 vorgesehen, dass die Arbeitsstelle nach Erreichen des Partieendes stillgesetzt wird, dass ein das Partieende anzeigendes Signal ausgegeben wird, das der Bedienperson signalisiert, dass für den Partiewechsel notwendige manuelle Schritte durchzuführen sind und dass die Arbeitsstelle nach Freigabe durch die Bedienperson selbsttätig weitere für den Partiestart erforderliche Schritte durchführt.To achieve the object is provided according to
Aufgrund dieser Vorgehensweise kann die Bedienperson auf unkomplizierte Art erkennen, an welcher Arbeitsstelle ein manuelles Eingreifen notwendig ist, wie beispielsweise das Auswechseln der Spinnkanne und des Rotors. Die Bedienperson erledigt die manuellen Arbeiten und gibt daraufhin die entsprechende Arbeitsstelle wieder frei, so dass die Arbeitsstelle alle weiteren, erforderlichen Arbeiten zum Partiewechsel autark durchführen kann. Nach der Freigabe kann die Arbeitsstelle mit der Garnproduktion der neuen Partie beginnen. Auf diese Weise werden Stillstände der Arbeitsstellen vermieden respektive verkürzt und der Wirkungsgrad der Offenend-Spinnmaschine erhöht.Due to this procedure, the operator can easily recognize at which point a manual intervention is necessary, such as the replacement of the spinning can and the rotor. The operator does the manual work and then releases the corresponding job again, so that the job can perform all other necessary work for batch change autarkic. After release, the job can begin to produce the yarn of the new lot. In this way, standstills of the jobs are avoided or shortened and increases the efficiency of the open-end spinning machine.
Vorzugsweise ist, wie in den Ansprüchen 2 und 3 beschrieben, ein erforderlicher Schritt für den Partiestart, der von der Arbeitsstelle selbsttätig durchgeführt wird, das Abrufen gespeicherter Partiedaten am Zentralrechner. Die Grundeinstellungen früherer Partien sind gespeichert und können autark von der jeweiligen Arbeitsstelle abgerufen werden, so dass diese als Basis für die aktuelle Partie dienen.Preferably, as described in
Die Ansprüche 4 und 5 veranschaulichen, dass durchzuführende Arbeitsschritte der Bedienperson das Auswechseln der Spinnkanne und/oder das Auswechseln von Spinnmitteln sind. In der Regel werden bei einem Partiewechsel nicht nur der in Spinnkannen vorgelegte Faserrohstoff, sondern ebenfalls Spinnmittel, wie beispielsweise der Rotor oder die Abzugsdüse, ausgetauscht.The
Weitere Einzelheiten der Erfindung sind einem nachfolgend anhand der Zeichnungen erläuterten Ausführungsbeispiel entnehmbar.Further details of the invention are shown in an embodiment explained below with reference to the drawings.
