Description

Steuerung für den Elektromotor einer Vorrichtung zum Bilden einer DreherkanteControl for the electric motor of a device for forming a leno edge
Die Erfindung betrifft eine Steuerung für den Elektromotor einer Vorrichtung zum Bilden einer Dreherkante auf einer Webmaschine mit Webschäften gemäß dem Oberbegriff der Ansprüche 1 und 2. Eine Vorrichtung zum Bilden einer Dreherkante ist beispielsweise aus der DE 44 05 776 C 1 bekannt. Hierbei ist ein elektrisch ansteuerbarer Stellmotor vorgesehen, der eine Dreherscheibe antreibt, wobei die Dreherscheibe den Läufer des elektrisch ansteuerbaren Stellmotors bildet. Die Dreherscheibe selbst besitzt mindestens zwei Fuhrungselemente für die Dreherfäden, wobei durch Verdrehung der Dreherfäden um den Schußfaden die Dreherkante gebildet wird.The invention relates to a control for the electric motor of a device for forming a leno edge on a weaving machine with heald frames according to the preamble of claims 1 and 2. A device for forming a leno edge is known for example from DE 44 05 776 C1. In this case, an electrically controllable servomotor is provided which drives a rotating disk, the rotating disk forming the rotor of the electrically controllable servomotor. The rotating disc itself has at least two guide elements for the leno threads, the leno edge being formed by twisting the leno threads around the weft thread.
Darüber hinaus ist aus der WO 97/24479 eine Vorrichtung zum Bilden einer Dreherkante bekannt, wobei der Rotor eines Elektromotors Arme zur Führung von Dreherfäden aufweist. Auch hierbei erfolgt die Bildung der Dreherkante durch Verdrehen der durch die Arme geführten Dreherfäden um den Schußfaden herum.In addition, from WO 97/24479 a device for forming a leno edge is known, the rotor of an electric motor having arms for guiding leno threads. Here too, the leno edge is formed by twisting the leno threads passed through the arms around the weft thread.
Diesen beiden bekannten Vorrichtungen ist gemein, daß zur Erstellung der Dreherkante ein Elektromotor vorgesehen ist, der zu jedem Zeitpunkt synchron zu der Bewegung der Webschäfte läuft. Allerdings kann dieser Elektromotor durchaus phasenversetzt zu der Bewegung der Webschäfte angetrieben sein, um beispielsweise ein frühzeitiges Abbinden des Schußfadens zu ermöglichen. Im eigentlichen Sinn erfolgt aber immer eine Orientierung der Bewegung des Rotors des Elektromotors an der Schaftbewegung. Hieraus wird deutlich, daß zur Durchführung dieses beschriebenen synchronen Laufes der Dreherkantenvorrichtung mit der Bewegung der Webschäfte kontinuierlich Daten, insbesondere von der Antriebswelle der Webmaschine zu der Dreherkantenvorrichtung übermittelt werden müssen, um eben den vorab beschriebenen synchronen Lauf des Elektromotors der Dreherkantenvorrichtung mit der Webmaschine bzw. mit der Bewegung der Webschäfte zu bewerkstelligen. Insofern ist auch vorgesehen, daß der Elektromotor beispielsweise über eine sogenannte elektrische Welle mit dem Antrieb der Webmschine gekoppelt ist. Das heißt nicht, daß bei der bekannten Vorrichtung die Steuerung der Dreherkantenvorrichtung webschaftabhängig ist; vielmehr ist die Steuerung und entsprechend die Rotationsbewegung des Rotors des Elektromotors der Dreherkantenvorrichtung webschaftunabhängig, weil eine unmittelbare mechanische Kupplung zwischen Webschäften und Dreherkantenvorrichtung nicht vorgesehen ist. Dennoch ist, wie bereits ausgeführt, die Dreherkantenvorrichtung mit der Webmaschine insofern gekuppelt, als die Bewegung der Dreherkantenvorrichtung, das heißt des Rotors des Elektromotors synchron zu der Bewegung der Antriebswelle der Webmaschine bzw. entsprechend zu der Bewegung der Webschäfte verläuft.These two known devices have in common that an electric motor is provided to create the leno edge, which runs at all times in synchronism with the movement of the heald frames. However, this electric motor can be driven out of phase with the movement of the heald frames, for example to allow the weft to set early. In the real sense, however, the movement of the rotor of the electric motor is always oriented to the shaft movement. From this it is clear that to carry out the described synchronous operation of the leno device with Movement of the heald frames has to be continuously transmitted data, in particular from the drive shaft of the loom to the leno selvedge device, in order to bring about the synchronous operation of the electric motor of the leno selvedge device described above with the loom or with the movement of the selvedges. In this respect it is also provided that the electric motor is coupled to the drive of the weaving machine, for example via a so-called electric shaft. This does not mean that in the known device the control of the leno edge device is dependent on the heald frame; rather, the control and correspondingly the rotational movement of the rotor of the electric motor of the leno selvedge device are independent of the heald frame, because a direct mechanical coupling between the heald frames and leno selvedge device is not provided. Nevertheless, as already stated, the leno selvedge device is coupled to the weaving machine insofar as the movement of the leno selvedge device, that is to say the rotor of the electric motor, runs synchronously with the movement of the drive shaft of the weaving machine or correspondingly with the movement of the heald frames.
Es hat sich nun allerdings herausgestellt, daß für die Bildung einer Dreherkante es völlig gleich ist, ob der Rotor des Elektromotors der Dreherkantenvorrichtung exakt und zu jedem Zeitpunkt synchron zu der Bewegung der Webmaschine - sprich der Antriebswelle bzw. den Webschäften der Webmaschine - läuft oder nicht. Wesentlich ist vielmehr ausschließlich, daß zu Beginn des Schußeintrages durch die Dreherkantenvorrichtung auch die beiden Dreherfäden sich in Fachöffnung befinden, und nach Abschluß des Schußeintrages die Dreherfäden in die Geschlossenfachstellung übergehen. Das heißt, es kommt ausschließlich darauf an, daß die jeweilige Endstellung, d. h. "Fach offen" bzw. "Fach geschlossen" durch die Dreherkantenvorrichtung spätestens dann erreicht wird, wenn die Webschäfte eine entsprechende Stellung einnehmen. Hieraus folgt, daß ein für jeden Zeitpunkt synchroner Bewegungsablauf zwischen der Bewegung des Rotors des Elektromotors mit der Bewegung der Webschäfte überhaupt nicht erforderlich ist.It has now been found, however, that for the formation of a leno selvedge it is completely the same whether the rotor of the electric motor of the leno selvedge device runs exactly and at all times in synchronism with the movement of the weaving machine - i.e. the drive shaft or the weaving shafts of the weaving machine . Rather, it is essential exclusively that at the beginning of the weft insertion through the leno selvedge device the two leno threads are also in the compartment opening, and after the weft entry has been completed the leno threads pass into the closed specialist position. This means that it is only important that the respective end position, ie "compartment open" or "compartment closed" is reached by the leno selvedge device at the latest when the heald frames assume a corresponding position. It follows from this that a movement sequence which is synchronous for each point in time between the movement of the rotor of the electric motor with the movement of the heald frames is not required at all.
Der Erfindung liegt daher die Aufgabe zugrunde eine Steuerung der eingangs genannten Art bereitzustellen, mit der der Elektromotor einer Vorrichtung zum Bilden einer Dreherkante derart angesteuert werden kann, daß die Abbindung zwar unabhängig von der Bewegung der Webschäfte erfolgt, aber dennoch in dem Zeitraum zwischen Fachoffen- und Fachgeschlossenstellung der Schäfte.The invention is therefore based on the object of providing a control of the type mentioned at the outset, with which the electric motor of a device for forming a leno edge can be controlled in such a way that the setting takes place independently of the movement of the heald frames, but nevertheless in the period between and shed locking.
Die Aufgabe wird nach einer ersten Variante entsprechend dadurch gelöst, daß der Steuerung des Elektromotors einen Startimpuls zu dem Zeitpunkt geliefert wird, zu dem von der Webmaschine der Beginn der Fachöffnung bzw. der Beginn des Schließens des Faches erfolgt. Eine andere Variante zur Lösung der Aufgabe besteht darin, die Steuerung des Elektromotors von dem Schußfadeneintrag abhängig zu gestalten. Insofern ist nach der zweiten Variante vorgesehen, daß der Steuerung des Elektromotors ein Startimpuls zu dem Zeitpunkt geliefert wird, zu dem der Eintrag des Schußfadens beginnt, bzw. der Schußeintrag beendet ist. In beiden Fällen ist allerdings erforderlich, daß die Rotationsgeschwindigkeit des Rotors des Elektromotors zum Öffnen und Schließen des Faches höher ist, als die Geschwindigkeit der Webschäfte zum Öffnen und Schließen des Faches. Der Vorteil dieser Steuerung liegt darin begründet, daß diese wesentlich einfacher im Aufbau und somit preisgünstiger ist, da nur wenige Parameter, nämlich genau zwei Parameter erforderlich sind, um die Vorrichtung zum Bilden der Dreherkante zu steuern. Insofern arbeitet diese Dreherkantenvorrichtung auch wesentlich störungsfreier, als eine mit der bekannten Steuerung.According to a first variant, the object is accordingly achieved in that the control of the electric motor is supplied with a start pulse at the time at which the weaving machine starts the opening of the compartment or the beginning of the closing of the compartment. Another variant for solving the problem is to make the control of the electric motor dependent on the weft thread entry. In this respect, it is provided according to the second variant that the control of the electric motor is supplied with a start pulse at the point in time at which the insertion of the weft thread begins or the weft entry is ended. In both cases, however, the speed of rotation of the rotor of the electric motor for opening and closing the compartment is higher than the speed of the heald frames for opening and closing the compartment. The advantage of this control lies in the fact that it is much simpler in construction and therefore cheaper, since only a few parameters, namely exactly two parameters, are required to control the device for forming the leno edge. In this respect, this leno selvedge device also works much more trouble-free than one with the known control.
Anhand der Zeichnungen wird die Erfindung nachstehend beispielhaft näher erläutert. Figur 1 zeigt schematisch die erfindungsgemäße Vorrichtung in Bezug auf ihre Stellung zum Gewebe, wobei die Schäfte und das Riet wegen der besseren Übersicht weggelassen sind;The invention is explained in more detail below by way of example with reference to the drawings. FIG. 1 shows schematically the device according to the invention in relation to its position in relation to the tissue, the stems and the reed being omitted because of the better overview;
Figur 2 zeigt eine schematische Darstellung des Verlaufs des Weges der Webschäfte bzw. Rotation des Rotors des Elektromotors der Dreherkantenvorrichtung über die Zeit.Figure 2 shows a schematic representation of the course of the path of the heald frames or rotation of the rotor of the electric motor of the leno device over time.
Zum besseren Verständnis der Vorrichtung sei zunächst noch einmal erläutert, wie die Dreherkantenvorrichtung arbeitet; diesbezüglich wird insbesondere auch auf den Offenbarungsgehalt gemäß der WO 97/24479 Bezug genommen.For a better understanding of the device, it should first be explained once again how the leno device works; in this regard, reference is made in particular to the disclosure content according to WO 97/24479.
Bei der in Figur 1 dargestellten Vorrichtung 1 ist ein insgesamt mit 10 bezeichneter Elektromotor vorgesehen, der zur Führung der Dreherfäden 20, 30 eine zentrische Bohrung 1 1 besitzt. Bei der dargestellten Ausführungsform, bei der die Rotationsachse quer zu den Kettfäden 40, d. h. im wesentlichen parallel zu den Schußfäden 50 verläuft, sind zwei Armpaare 60, 70 vorgesehen. Denkbar ist allerdings auch, daß die Vorrichtung mit nur einem Armpaar 60 arbeitet, das gewebeseitig am Rotor des Elektromotors angeordnet ist. Diese Armpaare sind ähnlich wie Propellerflügel ausgebildet und an dem Rotor angeordnet. Jedes ArmpaarIn the device 1 shown in FIG. 1, an electric motor, generally designated 10, is provided, which has a central bore 11 for guiding the leno threads 20, 30. In the illustrated embodiment, in which the axis of rotation is transverse to the warp threads 40, i.e. H. runs essentially parallel to the weft threads 50, two pairs of arms 60, 70 are provided. However, it is also conceivable that the device works with only one pair of arms 60, which is arranged on the fabric side of the rotor of the electric motor. These pairs of arms are designed similarly to propeller blades and are arranged on the rotor. Every pair of arms
60, 70 besteht aus zwei propellerfiügelartig ausgebildeten Armen 61 , 62 bzw. 71 , 72. Die beiden Armpaare 60, 70 verlaufen parallel zueinander und sind am jeweils stirnseitigen Ende des Rotors des Elektromotors 10 befestigt, wie sich dies aus der Figur 1 deutlich erkennen läßt. Die Arme60, 70 consists of two arms 61, 62 and 71, 72 designed like a propeller blade, respectively. The two pairs of arms 60, 70 run parallel to one another and are fastened to the respective front end of the rotor of the electric motor 10, as can be clearly seen from FIG . The poor
61 , 62 bzw. 71 , 72 sind endseitig hakenförmig gebogen ausgebildet und weisen im Bereich der hakenförmigen Biegung die Ösen 73, 74 bzw. 63, 64 auf. Diese Ösen dienen der Durchführung der Dreherfäden 20, 30, die von den Garnspulen 80, 90 abgezogen werden. Bei Rotation der Armpaare 60, 70 und hier insbesondere des Armpaares 60, entsteht im Bereich des Gewebes die Volldreherkante 100. Im Bereich der Zuführung der Verdrillung der Fäden (bei 1 10), die dadurch wieder aufgehoben wird, daß die Drehrichtung des Rotors nach einer bestimmten Anzahl Umdrehungen in einer Richtung umgekehrt wird. Das heißt, daß der Rotor des Elektromotors vorwärts und rückwärts läuft. Eine Entdrillung der Dreherkante 100 wird hierbei dadurch vermieden, daß zwischen den Dreherfäden die Schußfäden 50 einliegen.61, 62 and 71, 72 are bent in the shape of a hook at the end and have the eyelets 73, 74 and 63, 64 in the region of the hook-shaped bend. These eyelets serve to pass the leno threads 20, 30, which are drawn off from the bobbins 80, 90. When the arm pairs 60, 70 and here in particular the arm pair 60 rotate, the full-turn edge 100 is created in the area of the fabric. In the area of the feed of the Twisting of the threads (at 1 10), which is canceled again by reversing the direction of rotation of the rotor in one direction after a certain number of revolutions. This means that the rotor of the electric motor runs forwards and backwards. Untwisting of the leno edge 100 is avoided in that the weft threads 50 lie between the leno threads.
Aus Figur 2 ergibt sich der Bewegungsablauf zum einen der Webschäfte über die Zeit, und zum anderen des Rotors des Elektromotors der Dreherkantenvorrichtung ebenfalls über die Zeit. Hieraus wird erkennbar, daß zu dem Zeitpunkt, zu dem die Webschäfte schlußendlich offen sind, bereits der Rotor die Dreherfäden in Fachoffenstellung hält. Des weiteren ergibt sich aus dem Kurvenverlauf, daß der Rotor des Elektromotors in der Lage ist, das Fach wesentlich länger offen zu halten, als die Webschäfte. Insofern kann die erfindungsgemäße Vorrichtung mit einem kleineren Fach arbeiten und kann, was ebenfalls wesentlich ist, besonders weit vorne, nämlich zwischen den Schäften unmittelbar am Riet montiert werden. Auch wird durch derartiges langes Offenhalten des Faches den speziellen Anforderungen von Greiferwebmaschinen insofern Rechnung getragen, als der Zeitraum für den Greifer zum Verbleib im Fach länger wird.FIG. 2 shows the sequence of movements on the one hand of the heald frames over time, and on the other hand of the rotor of the electric motor of the leno selvedge device also over time. From this it can be seen that by the time the heald frames are finally open, the rotor is already holding the leno threads in the open position. It also follows from the course of the curve that the rotor of the electric motor is able to keep the compartment open much longer than the heald frames. In this respect, the device according to the invention can work with a smaller compartment and, which is also essential, can be mounted particularly far forward, namely between the shafts directly on the reed. By keeping the compartment open for such a long time, the special requirements of rapier weaving machines are taken into account insofar as the period for the rapier to remain in the compartment becomes longer.
Der Vorteil einer derartigen Steuerung besteht darin, daß diese wesentlich einfacher zu bewerkstelligen ist, da wesentlich weniger Steuersignale verarbeitet werden müssen, weil keine elektrische Welle oder elektrische Kurvenscheibe mit viel regelungstechnischem Aufwand nachgebildet werden muß. Das heißt, daß eine derartige Steuerung auch wesentlich preiswerter in der Herstellung ist. Ebenfalls zeigt sich, daß eine derartige Steuerung weniger anfällig ist. Zudem kommt diese Art der Ansteuerung der Verwendung von einfachen und damit preiswerten Schrittmotoren sehr entgegen. The advantage of such a control is that it is much easier to accomplish, since significantly fewer control signals have to be processed, because no electrical shaft or electrical cam plate has to be simulated with a lot of control technology. This means that such a control is also much cheaper to manufacture. It also shows that such a control is less susceptible. In addition, this type of control is very useful for the use of simple and therefore inexpensive stepper motors.
