Description

Die Erfindung betrifft eine Anlage und ein Verfahren gemäss Oberbegriff der unabhängigen Patentansprüche. Bei Anlagen zum Aufwickeln von parallel geführten Fäden, insbesondere an Bäum- oder Zettelanlagen, werden Kettfäden aus einem Spulengatter oder aus anderen Zuführeinrichtungen abgezogen und in einer vorgegebenen Fadenteilung auf einen Wickelkörper, insbesondere auf Kettbäume aufgewickelt. Die Fäden laufen durch mechanische Führungsanordnungen, wie insbesondere Führungskämme oder auch Oesenbretter, durch welche ein vorbestimmter Fadenabstand beim Aufwickeln gewährleistet wird. Ueblicherweise ist der Fadenabstand durch Einstellung oder Auswechslung der Führungsanordnungen, z.B. der Führungskämme einstellbar. Häufig laufen die Fäden dabei noch zwischen Führungsanordnung und Wickelkörper über eine Leit- oder Umlenkwalze oder auch über feststehende Führungsstangen.The invention relates to a system and a method according to the preamble of the independent claims. In systems for winding parallel threads, especially on tree or slip systems, warp threads are drawn off from a creel or from other feed devices and wound onto a winding body, in particular onto warp beams, in a predetermined thread division. The threads run through mechanical guide arrangements, such as in particular guide combs or eyelet boards, by means of which a predetermined thread spacing is ensured during winding. The thread spacing is usually determined by adjusting or replacing the guide arrangements, e.g. of the guide combs adjustable. Often, the threads still run between the guide arrangement and the winding former over a guide or deflection roller or also over fixed guide rods.

Beim Bremsen oder generell bei Betriebsunterbrechungen der Maschine (z.B. infolge Fadenbruch) können benachbarte Fäden miteinander in Kontakt kommen und sich dabei aufgrund abstehender Fasern miteinander verbinden oder sich sogar am Auflaufpunkt am Wickelkörper bzw. einer vorgelagerten Walze oder Stange überspringen.When braking or generally when the machine is out of operation (e.g. as a result of thread breakage), neighboring threads can come into contact with one another and thereby bond to one another due to protruding fibers or even jump over at the point of impact on the winding former or an upstream roller or rod.

Der Fadenabstand ist meist derart gering, dass durch die Führungsanordnung beim Anlaufen diese Verkettung einzelner Fäden nicht aufgehoben werden kann. Es kommt in der Folge zu ungleicher Wickeldichte und zur Ringbildung auf dem Wickelkörper. Abhilfe kann hier beim Stand der Technik nur ein Eingriff von Hand schaffen.The thread spacing is usually so small that the chaining of individual threads cannot be broken by the guide arrangement when starting. This results in uneven winding density and ring formation on the winding body. The only remedy in the state of the art is manual intervention.

Aufgabe der Erfindung ist es, die Nachteile des Bekannten zu vermeiden, insbesondere also ein Verfahren und eine Vorrichtung sowie eine Bäum- oder Zettelanlage zu schaffen, bei welcher das Aufwickeln übersprungener oder verbundener benachbarter Fäden vermieden wird.The object of the invention is to avoid the disadvantages of the known, in particular to create a method and an apparatus and a tree or slip system in which the winding up of skipped or connected adjacent threads is avoided.

Erfindungsgemäss wird diese Aufgabe in erster Linie gemäss Kennzeichen der Patentansprüche gelöst.According to the invention, this object is primarily achieved according to the characteristics of the claims.

Die Erfindung sieht dabei im Auslaufbereich der mechanischen Führungsanordnung, z.B. eines Führungskamms, eine Halteeinrichtung zum Fixieren der Fäden in einem Mindestabstand vor. Dieser Mindestabstand wird durch die Führungselemente der Führungsanordnung selbst vorgegeben, da die Führungselemente in jedem Fall als Abstandselemente für die Fäden dienen. Wenn die Fäden deshalb im Bereich unmittelbar hinter der Führungsanordnung im vorgegebenen Abstand gehalten und fixiert werden und so dann in dieser Relativlage an die darauffolgende Walze oder den darauffolgenden Wickelkörper weitergegeben und also mit Mindestabstand aufgewickelt werden, wird einerseits Ueberspringen beseitigt und andererseits eine streckenweise Verbindung zwischen zwei Fäden im nachfolgenden Wickelprozess wieder rückgängig gemacht.The invention sees in the outlet area of the mechanical guide arrangement, e.g. a guide comb, a holding device for fixing the threads in a minimum distance in front. This minimum distance is specified by the guide elements of the guide arrangement itself, since the guide elements serve in each case as spacer elements for the threads. If the threads are therefore held and fixed at a predetermined distance in the area immediately behind the guide arrangement and are then passed on in this relative position to the subsequent roller or the following winding former and are therefore wound up with a minimum distance, on the one hand skipping is eliminated and on the other hand a section-wise connection between two Threads undone in the subsequent winding process.

Besonders vorteilhaft ist es, wenn eine Steuereinrichtung vorgesehen ist, welche die Halteanordnung bei einer Unterbrechung des Wickelvorgangs und/oder vor dem Wiederanfahren des Wickelvorgangs automatisch aktiviert. Bei einer Bäum- oder Zettelanlage lässt sich eine derartige Steuereinrichtung besonders einfach in die vorhandene Steueranordnung zum Stillsetzen und Anfahren der Anlage integrieren oder jedenfalls baulich in der Gesamt-Steueranordnung der Anlage unterbringen.It is particularly advantageous if a control device is provided which automatically activates the holding arrangement when the winding process is interrupted and / or before the winding process starts again. In the case of a tree or slip plant, such a control device can be integrated particularly easily into the existing control arrangement for stopping and starting the plant, or in any case can be structurally accommodated in the overall control arrangement of the plant.

Zweckmässig ist es dabei, wenn entweder mittels der genannten Steuereinrichtung oder mittels einer separaten Steuereinrichtung die Halteeinrichtung bei Beginn des Wickelvorgangs automatisch etwa mit Geschwindigkeit der Fäden in Richtung zur nachfolgenden Walze bzw. zum Wickelkörper hin verlagert wird, um die Fäden in der fixierten Relativlage zu übergeben. Optimal ist es dabei, wenn die Geschwindigkeit der Halteeinrichtung geringer ist als die Fadengeschwindigkeit, so dass die Fäden gespannt bleiben.It is useful if either by means of the control device mentioned or by means of a separate control device at the start of the winding process, the holding device is automatically displaced at approximately the speed of the threads in the direction of the subsequent roller or towards the winding body, in order to transfer the threads in the fixed relative position. It is optimal if the speed of the holding device is lower than the thread speed, so that the threads remain tensioned.

Die Fixierung der Fäden auf der Halteanordnung lässt sich besonders einfach erreichen, wenn diese unter der Fadenschar angehoben wird, so dass die Fäden über das Halteelement gespannt werden. Dabei werden die Fäden durch Reibschluss gehalten.The fixing of the threads on the holding arrangement can be achieved particularly easily if it is raised under the thread sheet, so that the threads are stretched over the holding element. The threads are held by friction.

Selbst wenn formschlüssige Halterung der Fäden im Mindestabstand gewünscht wird, kann das Halteelement auch aus zwei gegeneinander gepressten Einzel-Elementen bestehen, welche die Fadenschar mit Kraft- und/oder Formschluss halten.Even if positive locking of the threads at a minimum distance is desired, the holding element can also consist of two individual elements pressed against one another, which hold the thread sheet with a force fit and / or form fit.

Besonders vorteilhaft ist es, wenn die Oberfläche des Halteelements mit Fadenführungen, insbesondere mit Rillen ausgebildet ist.It is particularly advantageous if the surface of the holding element is designed with thread guides, in particular with grooves.

Durch die Halterung selbst lässt sich auf besonders einfache Weise der Mindestabstand automatisch vergrössern, wenn kammartige Vorsprünge vorgesehen sind, die auf die Führungselemente der mechanischen Führungsanordnung ausgerichtet sind und ggf. den Changierbewegungen der Führungselemente folgen.By means of the holder itself, the minimum distance can be automatically increased in a particularly simple manner if comb-like projections are provided which are aligned with the guide elements of the mechanical guide arrangement and possibly follow the traversing movements of the guide elements.

Sofern die Kammteilung und damit der Abstand der Einzelfäden bei einer Bäum- oder Zettelanlage veränderbar ist, lässt sich die Halteeinrichtung entweder mit einem passenden Halteelement mit fluchtenden Fadenführungen versehen oder es kann vorteilhaft ein Halteelement mit einstellbarem Abstand der Fadenführungen eingesetzt werden.If the comb pitch and thus the spacing of the individual threads in a tree or slip system can be changed, the holding device can either be provided with a suitable holding element with aligned thread guides or a holding element with an adjustable spacing of the thread guides can advantageously be used.

Die Erfindung schafft auf optimal einfache Weise eine Vorrichtung und ein Verfahren, mit welchem Störungen beim Aufwickeln von parallel geführten Fäden auf Wickelkörper vermieden werden. Die Anordnung kann dabei sowohl von Hand bedient werden als auch automatisch durch Steuereinrichtungen angesteuert und dem Wickelvorgang angepasst werden.The invention provides, in an optimally simple manner, a device and a method with which disruptions in the winding of threads guided in parallel on winding bodies are avoided. The arrangement can be operated manually as well as controlled automatically by control devices and adapted to the winding process.

Der technische Fortschritt und der erfinderische Inhalt des Anmeldungsgegenstands wird dabei sowohl durch die verschiedenen Einzelmerkmale gemäss Ansprüchen als auch durch Kombination und Unterkombination der einzelnen Merkmale gewährleistet.The technical progress and the inventive content of the subject matter of the application are guaranteed both by the various individual features according to claims and by a combination and sub-combination of the individual features.

Gemäss Figur 1 und la werden bei einer Zettelanlage 1 in bekannter Weise Fäden 2 von den Spulen 3 eines Zettelgatters 4 abgezogen. Die Fäden werden dabei in einem Kamm 5 mit Kammnadeln 6 zusammengeführt, bevor sie über eine Umlenkwalze 7 und/oder einer vorgelagerten Stange 7a, die als Entstaubungsblasrohr ausgebildet sein kann, laufen und auf einen Wickelkörper 8 aufgewickelt werden.According to FIGS. 1 and 1, threads 2 are drawn off from the bobbins 3 of a slip gate 4 in a known way in a slip system 1. The threads are brought together in a comb 5 with comb needles 6 before they run over a deflection roller 7 and / or an upstream rod 7a, which can be designed as a dedusting blowpipe, and are wound onto a winding body 8.

Durch den Kamm 5 bzw. die Kammnadeln 6 soll dabei sichergestellt werden, dass die Fäden 2 parallel und etwa mit gleichem Abstand auf den Wickelkörper 8 aufgewickelt werden. Vor allem beim Abbremsen der Maschine und bei damit nachlassender Fadenspannung oder durch Eingriffe bei einem Fadenbruch gelangen dabei manchmal benachbarte Fäden aneinander und verbinden sich mit ihren abstehenden textilen Fasern oder überspringen einander sogar am Auflaufpunkt auf der Stange 7a und/oder der Umlenkwalze 7 und/oder am Wickelkörper 8, wie dies durch die Fäden 2a, 2b in Figur la schematisch dargestellt ist. Dies kann ersichtlicherweise sowohl bei Anlagen mit der Umlenkwalze 7 eintreten als auch bei anderen Anordnungen, bei denen z.B. parallel geführte Fäden direkt von einer Führungsanordnung 5, 6 einem Wickelkörper 8 zugeführt werden. Auch ist die Führungsanordnung ersichtlicherweise nicht auf den Einsatz eines Kamms 5 beschränkt. In der Praxis sind auch Führungsanordnungen mit Oesenbrettern oder anderen Abstandshaltern bekannt oder einsetzbar.The comb 5 or the comb needles 6 is intended to ensure that the threads 2 are wound onto the winding body 8 in parallel and at approximately the same distance. Especially when braking the machine and thus decreasing thread tension or by interventions in the event of a thread break, adjacent threads sometimes come together and connect with their protruding textile fibers or even jump over each other at the point of impact on the rod 7a and / or the deflection roller 7 and / or on the winding body 8, as is shown schematically by the threads 2a, 2b in FIG. This can obviously occur both in systems with the deflection roller 7 and in other arrangements in which e.g. threads guided in parallel can be fed directly from a guide arrangement 5, 6 to a winding body 8. The guide arrangement is also evidently not limited to the use of a comb 5. In practice, guide arrangements with eyelet boards or other spacers are known or can be used.

Die Zettelanlage wird in bekannter Weise von einem Bedienungspult 20 aus bedient und gesteuert, wobei das Bedienungspult auch eine Steuereinrichtung zum Steuern des Abschaltens und Anfahrens der Zettelanlage 1 und aller ihrer Aggregate aufweist.The slip system is operated and controlled from a control panel 20 in a known manner, the control panel also has a control device for controlling the switching off and starting of the slip system 1 and all of its units.

Gemäss Figur 2 bis 4 ist im Zwischenraum zwischen dem Kamm 5 und der Umlenkwalze 7 eine Halteeinrichtung 9 vorgesehen, die ein als quer zu den Fäden 2 verlaufende Stange 10 ausgebildetes Halteelement aufweist. Die Stange 10 ist auf einer gestrichelt angedeuteten Bewegungsbahn 11 aus einer ersten Position I in eine zweite Position II anhebbar. Dabei werden die Fäden 2 angehoben und in eine gespannte Lage 2' gebracht, wobei sie über die Stange 10 gespannt und dabei fixiert werden. Wie aus Figur 3 ersichtlich ist, erfolgt diese Fixierung unmittelbar neben den Kammnadeln 6, so dass der durch die Dicke der Kammnadeln 6 bestimmte Mindestabstand auch zwischen den zwei Fäden 2a und b erhalten bleibt, die im Bereich der Umlenkwalze 7 miteinander verbunden sind. Im weiteren Verlauf wird beim Wiederanfahren der Zettelanlage die Stange 10 durch Drehen der Achse 12 gleichgerichtet mit den geförderten Fäden 2 in Richtung des Pfeils A (Figur 3) zur Umlenkwalze 7 hin in die Position III (Figur 2 und 4) verlagert. Dadurch bleibt der mittels Stange 10 fixierte Abstand a erhalten und die Fäden 2a, 2b werden mit diesem Abstand der Umlenkwalze 7 übergeben. Auf diese Weise ist die Verbindung der Fäden 2a, 2b, wieder aufgehoben und im Betriebsablauf sind keine Wickelfehler zu befürchten. Die Stange 10 wird jetzt durch weiteres Drehen der Achse 12 wieder zurück in die Ausgangsposition I gemäss Figur 2 verlagert.According to FIGS. 2 to 4, a holding device 9 is provided in the space between the comb 5 and the deflecting roller 7, which has a holding element designed as a rod 10 running transversely to the threads 2. The rod 10 can be raised from a first position I to a second position II on a movement path 11 indicated by dashed lines. The threads 2 are raised and brought into a tensioned position 2 ', being tensioned over the rod 10 and being fixed in the process. As can be seen from FIG. 3, this fixation takes place immediately next to the comb needles 6, so that the minimum distance determined by the thickness of the comb needles 6 is also maintained between the two threads 2a and b, which are connected to one another in the region of the deflection roller 7. In the further course, the rod 10 is shifted in the same direction with the conveyed threads 2 in the direction of arrow A (FIG. 3) towards the deflecting roller 7 into position III (FIGS. 2 and 4) by turning the axis 12 again. As a result, the distance a fixed by means of the rod 10 is maintained and the threads 2a, 2b are transferred to the deflection roller 7 at this distance. In this way, the connection of the threads 2a, 2b is removed again and no winding errors are to be feared in the course of operation. The rod 10 is now moved back to the starting position I according to FIG. 2 by further rotation of the axis 12.

In Figur 2 ist mit 10a eine zweite Stange angedeutet. Diese Stange kann analog der Stange 10 über den Fäden 2 entlang einer Bewegungsbahn 11a bewegt werden. Dadurch kann erreicht werden, dass die Stange 10 und die Stange 10a in der Position 2 gegeneinander geführt werden, wodurch die Fäden 2 in dieser Position kraftschlüssig oder formschlüssig zwischen den zwei Stangen 10, 13 oder 10a und 13 fixiert werden. Auf diese Weise lässt sich die Fixierung der Fäden 2 zusätzlich sichern, wenn Fixierung durch Vorspannung mittels einer Stange 10 alleine nicht ausreicht, um die Fäden 2 entsprechend festzulegen.In Figure 2, a second rod is indicated by 10a. Analogous to the rod 10, this rod can be moved over the threads 2 along a movement path 11a. It can thereby be achieved that the rod 10 and the rod 10a are guided against each other in the position 2, whereby the threads 2 are fixed in a non-positive or positive manner between the two rods 10, 13 or 10a and 13 in this position. To this In this way, the fixation of the threads 2 can be additionally secured if fixation by pretensioning by means of a rod 10 alone is not sufficient to fix the threads 2 accordingly.

Die Halte-Einrichtung 9 wird, wie in Figur 2 schematisch dargestellt, durch einen Motor 18 angetrieben. Der Motor 18 wird von einer Steuereinrichtung 19 mit Stellsignalen gespeist. Die Steuereinrichtung 19 kann dabei derart von der im Bedienungspult 20 angeordneten Steuereinrichtung für die Zettelanlage 1 angesteuert werden, dass jeweils automatisch bereits nach dem Abstellen der Anlage 1, jedenfalls aber vor dem Wiederanfahren der Anlage 1, die Halteeinrichtung 9 in die Position II gebracht, also aktiviert wird. Selbstverständlich können die Steuereinrichtung 19 und/oder die Halteeinrichtung 9 auch manuell und auch im Lauf aktiviert werden.As shown schematically in FIG. 2, the holding device 9 is driven by a motor 18. The motor 18 is fed with control signals by a control device 19. The control device 19 can be controlled by the control device for the slip system 1 arranged in the control panel 20 in such a way that the holding device 9 is automatically brought into position II, i.e. after the system 1 has been switched off, but in any case before the system 1 is restarted is activated. Of course, the control device 19 and / or the holding device 9 can also be activated manually and also during the run.

Beim Ausführungsbeispiel gemäss Figur 5 und 6 weist die Halteeinrichtung 9 eine Querstange 10 als Halteelement auf, deren Oberfläche mit Fadenführungen 13 versehen ist. Die Fadenführungen 13 bestehen aus keilförmig gebogenen Kammelementen, deren Spitzen jeweils mit den Kammnadeln 6 fluchten. Figur 6 zeigt dabei schematisch die Stange 10 in einer Stellung analog Position I gemäss Figur 2. Die Fäden 2a, 2b sind analog Figur 3 miteinander verbunden und liegen deshalb beidseitig an der sie trennenden Kammnadel 6 an. Beim Anheben der Stange 10, wie in Figur 6a dargestellt, schieben sich die Spitzen der Fadenführungen 13 zwischen die einzelnen Fäden 2. In Bezug auf die miteinander verbundenen Fäden 2a und 2b bedeutet dies, dass die Fadenführung 13 die beiden Fäden 2a und 2b weiter voneinander trennt und gemäss Figur 6 b entsprechend der Keilform der Fadenführungen 13 völlig auf Abstand bringt, sobald die höchste Position (analog Position II in Figur 2) erreicht ist. Die Fäden werden damit in einem Abstand voneinander gehalten und fixiert, der breiter ist als die Dicke der Kammnadeln 6, und der durch den Abstand der Fadenführungen auf der Stange 10 bestimmt wird.In the exemplary embodiment according to FIGS. 5 and 6, the holding device 9 has a cross bar 10 as a holding element, the surface of which is provided with thread guides 13. The thread guides 13 consist of wedge-shaped curved comb elements, the tips of which are each aligned with the comb needles 6. FIG. 6 schematically shows the rod 10 in a position analogous to position I according to FIG. 2. The threads 2a, 2b are connected to one another analogously to FIG. 3 and are therefore on both sides of the comb needle 6 separating them. When the rod 10 is raised, as shown in FIG. 6a, the tips of the thread guides 13 slide between the individual threads 2. With respect to the threads 2a and 2b connected to one another, this means that the thread guide 13 further separates the two threads 2a and 2b separates and according to Figure 6 b according to the wedge shape of the thread guides 13 completely apart as soon as the highest position (analogous to position II in Figure 2) is reached. The threads are thus held and fixed at a distance from one another which is wider than the thickness of the comb needles 6 and which is determined by the distance between the thread guides on the rod 10 is determined.

Figur 7 zeigt ein Ausführungsbeispiel, bei welchem ein ebenfalls als Stange 10 ausgebildetes Halteelement mit Rillen 14 versehen ist, welche die Fäden 2 in dem durch die Kammnadeln 6 definierten Abstand fixieren.FIG. 7 shows an exemplary embodiment in which a holding element, likewise designed as a rod 10, is provided with grooves 14 which fix the threads 2 at the distance defined by the combing needles 6.

Figur 8 zeigt ein Ausführungsbeispiel, bei welchem als Halteelement eine Trägerstange 15 vorgesehen ist, in welcher verschiebbare Befestigungselemente 15a angeordnet sind. Die Befestigungselemente 15a tragen scharnierartig ausgebildete Fadenführungen 13, deren Abstand und Neigungswinkel durch Verschieben der Befestigungselemente 15a verstellbar ist. Dadurch lassen sich die Fadenführungen an den Abstand der Kammnadeln 6 eines Kamms 5 anpassen.Figure 8 shows an embodiment in which a support rod 15 is provided as a holding element, in which displaceable fastening elements 15a are arranged. The fastening elements 15a carry hinge-like thread guides 13, the distance and angle of inclination of which can be adjusted by moving the fastening elements 15a. As a result, the thread guides can be adapted to the distance between the comb needles 6 of a comb 5.

Figur 9 zeigt ein Ausführungsbeispiel, bei welchem als Halteelement eine Trägeranordnung 16 vorgesehen ist, die eine Spiralfeder 17 trägt. Die Trägeranordnung lässt sich breiter oder schmäler einstellen, wodurch die Spiralfeder 17 mehr oder weniger gespannt wird und womit der Abstand der einzelnen Feder-Gänge ebenfalls an den Abstand der Kammnadeln 6 eines Kamms 5 angepasst werden kann.FIG. 9 shows an exemplary embodiment in which a support arrangement 16 is provided as the holding element, which supports a spiral spring 17. The carrier arrangement can be set wider or narrower, as a result of which the spiral spring 17 is tensioned to a greater or lesser extent and with which the distance between the individual spring courses can also be adapted to the distance between the comb needles 6 of a comb 5.
