Abstract
Description
Die Erfindung betrifft ein Verfahren zum Betreiben einer Webmaschine mit einem ersten Antriebsmotor, der ein erstes Element antreibt, beispielsweise eine Weblade, und mit wenigstens einem zweiten Antriebsmotor, der ein zweites Element antreibt, beispielsweise eine Fachbildungseinrichtung.The invention relates to a method for operating a weaving machine with a first drive motor which drives a first element, for example a sley, and with at least one second drive motor which drives a second element, for example a shedding device.
Bei Webmaschinen müssen die Bewegungen der einzelnen Elemente zeitlich aufeinander abgestimmt sein. Um diese zeitliche Abstimmung bei dem Einsatz unabhängiger Antriebsmotoren zu erhalten, ist es bekannt, die Drehwinkelposition einer Hauptwelle, die insbesondere eine Weblade antreibt, zu erfassen und den oder die Antriebsmotoren der anderen Elemente mit diesen Drehwinkelpositionen zu synchronisieren. Diese Synchronisation bereitet Probleme, da die Hauptwelle sich mit wechselnder Drehgeschwindigkeit bewegt. Vor dem Anschlagen eines eingetragenen Schussfadens nimmt die Drehgeschwindigkeit der Hauptwelle ab. Wenn die Weblade mit dem Webblatt in die rückwärtige Position gelangt, so nimmt die Drehgeschwindigkeit der Hauptwelle zu. Wenn angestrebt wird, beispielsweise den Antriebsmotor einer Fachbildungseinrichtung mit dem Hauptantriebsmotor, der die Weblade antreibt, zu synchronisieren, so muss der Antriebsmotor der Fachbildungseinrichtung ebenso die ungleichmäßige Bewegung ausführen. Das führt dazu, dass der ohnehin schon einer hohen Belastung ausgesetzte Antriebsmotor einer Fachbildungseinrichtung und auch die Fachbildungseinrichtung weiteren Belastungen ausgesetzt sind, die an sich nicht notwendig sind.In weaving machines, the movements of the individual elements must be timed to each other. In order to obtain this timing in the use of independent drive motors, it is known to detect the rotational angular position of a main shaft, which drives in particular a sley, and to synchronize the drive motor or the other elements with these rotational angular positions. This synchronization causes problems as the main shaft moves at varying rotational speeds. Before striking a registered weft thread, the rotational speed of the main shaft decreases. When the batten with the reed reaches the rearward position, the rotational speed of the main shaft increases. When it is desired to synchronize, for example, the drive motor of a shedder with the main drive motor which drives the sley, the shifter drive motor must also perform the nonuniform motion. The result of this is that the drive motor, which is already exposed to a high load, to a shed-forming device and also the shed-forming device are subjected to further loads which are not necessary per se.

Ein Verfahren zum Betreiben einer Webmaschine mit einem ersten Antriebsmotor, der ein erstes Element antreibt, und mit wenigstens einem zweiten Antriebsmotor, der ein zweites Element antreibt, sowie eine Webmaschine mit einem ersten Antriebsmotor, der ein erstes Element antreibt, und mit wenigstens einem zweiten Antriebsmotor, der ein zweites Element antreibt, sind aus
Der Erfindung liegt die Aufgabe zugrunde, eine Webmaschine der eingangs genannten Art so zu betreiben, dass für die Antriebsmotoren von Elementen möglichst keine unnötigen Belastungen zu überwinden sind.The invention has for its object to operate a loom of the type mentioned so that as far as possible no unnecessary loads to overcome for the drive motors of elements.
Diese Aufgabe wird gelöst von den Gegenständen mit den Merkmalen der Ansprüche 1 und 6.This object is achieved by the objects with the features of claims 1 and 6.
Die Erfindung geht von der Überlegung aus, dass die Elemente einer Webmaschine nicht ständig während des gesamten Webzyklus zueinander exakt synchronisiert sein müssen, sondern dass sich die einzelnen Elemente nur in bestimmten Drehwinkelpositionen in geeigneten Positionen befinden müssen. Während des restlichen Webzyklus können sie dagegen Positionen einnehmen, die weitgehend voneinander unabhängig sind. Die imaginäre Synchronisationswelle ist das Element, nach welchem nicht nur die zusätzlichen Elemente wie Fachbildungseinrichtungen oder Kanteneinleger oder Aufwickeleinrichtungen odgl. ausgerichtet werden, sondern auch die Weblade. Die einzelnen Elemente einschließlich der Weblade werden somit nicht mehr zu einer Hauptwelle synchronisiert, sondern zu der imaginären Synchronisationswelle, zu der auch die Weblade synchronisiert wird. Die einzelnen Elemente können deshalb ihre Bewegungen so ausführen, dass möglichst geringe Belastungen für ihre Antriebsmotoren und / oder für die Elemente selbst auftreten, ohne dass der Bewegungsverlauf über 360° auf die anderen Elemente und insbesondere auf die Bewegung der Weblade abgestimmt ist. Die Erfindung bietet insbesondere auch bei dem Start einer Webmaschine Vorteile. Ein Antriebsmotor, der Bauelemente mit größerer Masse antreibt, beispielsweise der Antriebsmotor der Weblade, kann früher gestartet werden, als beispielsweise ein Antriebsmotor für eine Fachbildungseinrichtung. Die Startzeitpunkte der Antriebsmotoren können so abgestimmt werden, dass sie, d.h. die von ihnen angetriebenen Elemente, die jeweils gewünschte Drehwinkelposition zu dem richtigen Zeitpunkt einnehmen. Beispielsweise kann der Antriebsmotor einer Fachbildungseinrichtung so gestartet werden, dass die Kettfäden sich bei einem Winkel von 320° der imaginären Synchronisationswelle kreuzen, während der Antriebsmotor der Weblade so gestartet wird, dass das Anschlagen eines Schussfadens bei 0° oder 360° der imaginären Synchronisationswelle erfolgt. Dabei ist nicht der Zeitpunkt des Starts der Antriebsmotoren wichtig, sondern vielmehr, dass die davon angetriebenen Elemente sich zum richtigen Zeitpunkt in der richtigen Position befinden.The invention is based on the consideration that the elements of a weaving machine do not have to be constantly synchronized with one another exactly during the entire weaving cycle, but that the individual elements only have to be in suitable positions at certain angular positions. During the rest of the web cycle, they can take positions that are largely independent of each other. The imaginary synchronization wave is the element according to which not only the additional elements such as shedding devices or edge feeders or winders or the like. be aligned, but also the batten. The individual elements including the batten are thus no longer synchronized to a main shaft, but to the imaginary synchronization wave to which the sley is synchronized. The individual elements can therefore perform their movements so that the lowest possible loads on their drive motors and / or for the elements themselves, without the course of motion being tuned over 360 ° to the other elements and in particular to the movement of the batten. The invention also offers advantages in particular when starting a weaving machine. A drive motor that drives components of greater mass, for example, the drive motor of the batten, can be started earlier than, for example, a drive motor for a shedding device. The starting times of the drive motors can be tuned so that they, ie, the elements driven by them, each occupy the desired rotational angular position at the right time. For example, the drive motor of a shedding device can be started so that the warp threads intersect at an angle of 320 ° of the imaginary synchronization shaft, while the drive motor of the sley is started so that striking a weft at 0 ° or 360 ° of the imaginary synchronization wave. It is not the timing of the start of the drive motors that is important, but rather that the elements driven by them are in the right position at the right time.
Bei einer Webmaschine mit einem Antriebsmotor, der ein erstes Elemente antreibt, beispielsweise eine Weblade, und mit wenigstens einem zweiten Antriebsmotor, der ein zweites Element antreibt, beispielsweise eine Fachbildungseinrichtung, wird die Erfindung dadurch verwirklicht, dass eine Steuer- und Regeleinrichtung vorgesehen ist, die einen Drehwinkelverlauf für eine imaginäre Synchronisationswelle der Webmaschine bildet und an jeweils eigene Steuer- und Regeleinheiten der Antriebsmotoren weiterleitet, die jedes der von den Antriebsmotoren angetriebenen Elemente in wenigstens einer vorgegebenen Drehwinkelposition zu der imaginären Synchronisationswelle synchronisieren.In a weaving machine with a drive motor that drives a first element, such as a sley, and with at least one second drive motor that drives a second element, such as a shedding device, the invention is realized in that a control and regulating device is provided which forms a rotation angle course for an imaginary synchronization shaft of the weaving machine and forwards to their own control units of the drive motors, which synchronize each of the driven by the drive motors elements in at least one predetermined rotational angular position to the imaginary synchronization shaft.
In Ausgestaltung der Erfindung wird vorgesehen, dass ein eigener Antriebsmotor für die Fachbildungsmittel vorgesehen ist, der von einem Hauptantriebsmotor, der die Weblade antreibt, unabhängig ist.In an embodiment of the invention it is provided that a separate drive motor is provided for the shed forming means, which is independent of a main drive motor which drives the sley.
Da der Antriebsmotor der Fachbildungsmittel von dem Hauptantriebsmotor unabhängig ist, kann er mit optimierten Bedingungen arbeiten.Since the drive motor of the shed forming means is independent of the main drive motor, it can operate with optimized conditions.
Bei einer einfachen Ausführungsform, die nahezu keine Änderungen an einer Webmaschine erfordert, wird vorgesehen, dass der Antriebsmotor der Fachbildungsmittel an einem Rahmen der Webmaschine angebracht und über ein elastisches Kupplungselement mit Antriebselementen der Fachbildungsmittel verbunden ist. Das elastische Kupplungselement ist zumindest sinnvoll, um Schwingungen oder Vibrationen nicht von den Fachbildungsmitteln auf die anderen Elemente der Webmaschine und umgekehrt zu übertragen.In a simple embodiment, which requires almost no changes to a loom, it is provided that the drive motor of the shed forming means is attached to a frame of the loom and connected via an elastic coupling element with drive elements of the shed forming means. The elastic coupling element is at least useful not to transmit vibrations or vibrations from the shedding means to the other elements of the loom and vice versa.
Bei einer anderen Ausgestaltung der Erfindung wird vorgesehen, dass der Antriebsmotor der Fachbildungsmittel an einem Gehäuse befestigt ist, das Antriebselemente für Fachbildungsmittel enthält. Damit ist der Antriebsmotor der Fachbildungsmittel von den übrigen Elementen der Webmaschine weitestgehend getrennt, so dass einerseits Schwingungen und Vibrationen nicht gegenseitig übertragen werden, während andererseits keine Umlenkungen von Antriebskräften notwendig sind.

Ein erster Antriebsmotor 10 treibt über eine Getriebestufe 11 eine Antriebswelle 12 für eine Weblade 13 an. Ein zweiter Antriebsmotor 44 treibt über eine Getriebestufe 45 eine beispielsweise als Schaftmaschine ausgeführte Fachbildungseinrichtung 46 an, die über Gestänge 47 mit nicht dargestellten Webschäften verbunden ist.A
Während eines Webzyklus führt die Welle 12, die üblicherweise als Hauptwelle bezeichnet wird, eine Drehung um 360° aus. Bei 0° oder 360° schlägt das auf der Weblade 13 angeordnete Webblatt einen eingetragenen Schussfaden an. Die von der Fachbildungseinrichtung 46 und dem Gestänge 47 angetriebenen, d.h. angehobenen und abgesenkten Webschäfte, bilden ein Webfach, in das ein Schussfaden eingetragen wird. Nach dem Schusseintrag wird das Webfach durch Anheben und Absenken anderer Webschäfte gewechselt, wonach der nächste Schussfaden eingetragen wird. Der Wechsel des Webfaches erfolgt zum Beispiel bereits, bevor der eingetragene Schussfaden endgültig angeschlagen ist. Hierbei kreuzen sich die Kettfäden der sich nach oben bewegenden Webschäfte mit den Kettfäden der sich nach unten bewegenden Webschäfte. Diese Kreuzung erfolgt beispielsweise bei einem Winkel von 320° der Welle 12, d.h. 40° vor dem Anschlagen des eingetragenen Schussfadens.During a weaving cycle, the
Um die Bewegungen der Weblade 13 und der Fachbildungseinrichtung 46 zu synchronisieren, bildet eine Regel- und Steuereinrichtung 48 aufgrund von mittels einer Eingabeeinheit 55 eingegebener Daten einen Drehwinkelverlauf für eine imaginäre Synchronisationswelle. Die beiden Antriebsmotoren 10 und 44 werden jeweilig abhängig von dem Drehwinkelverlauf dieser imaginären Synchronisationswelle betrieben. Für den Antriebsmotor 10 der Weblade 13 ist eine Steuer- und Regeleinheit 49 vorgesehen, in die die Daten mittels einer Eingabeeinheit 53 für das Betreiben in Abhängigkeit von dem Drehwinkelverlauf der imaginären Synchronisationswelle eingegeben werden. An die Steuer- und Regeleinheit 49 ist ein Drehpositionsgeber 50 angeschlossen, der die Position der Welle 12 und damit die Position der Weblade 13 angibt. Bei einer anderen Ausführungsform ist ein Drehpositionsgeber 57 auf der Welle des Antriebsmotors 10 angeordnet. Die Steuer- und Regeleinheit 49, die an den Antriebsmotor 10 angeschlossen ist, regelt diesen Antriebsmotor 10 nach Soll-Werten, die von dem Drehwinkelverlauf der imaginären Synchronisationswelle abgeleitet sind, derart, dass die Weblade 13 beispielsweise in einer Winkelposition (0° oder 360°) mit der imaginären Synchronisationswelle synchronisiert ist, d.h. beim Anschlagen eines Schussfadens. Die Steuer- und Regeleinheit 49 kann für den Antriebsmotor 10 auch ein Programm vorgeben, das insbesondere der
Die Informationen über den Drehwinkelverlauf der imaginären Synchronisationswelle werden auch an eine Steuer- und Regeleinheit 51 weitergeleitet, die dem Antriebsmotor 44 zugeordnet ist. Der Antriebsmotor 44 wird in Abhängigkeit von dem Drehwinkelverlauf der imaginären Synchronisationswelle in der Weise betrieben, dass ebenfalls bei einer vorgegebenen Drehwinkelposition, beispielsweise bei einer Drehwinkelposition von 320° der imaginären Synchronisationswelle eine bestimmte Position von dem Gestänge 47 der Fachbildungseinrichtung 46 eingenommen wird. An die Steuer- und Regeleinheit 51 ist eine Eingabeeinheit 54 angeschlossen, mit der die Daten das Betreiben in Abhängigkeit von der imaginären Synchronisationswelle eingegeben werden. Um diese Position zu erkennen, ist der Fachbildungseinrichtung 46 ein Drehpositionsgeber 52 zugeordnet, der an die Steuer- und Regeleinheit 51 angeschlossen ist. In der Zeichnung ist angedeutet, dass dieser Drehpositionsgeber 52 die Position des Gestänges 47 erfasst. Stattdessen kann jedoch auch ein Drehpositionsgeber 56 auf der Welle 58 der Fachbildungseinrichtung 46 angeordnet sein oder ein Drehpositionsgeber 59 auf der Welle des Antriebsmotors 44.The information about the rotation angle of the imaginary synchronization shaft are also forwarded to a control and
Da die Antriebsmotoren 10 und 44 völlig von einander getrennt sind und auch nicht miteinander synchronisiert sind, sondern indirekt über die imaginäre Synchronisationswelle miteinander in Beziehung stehen, können sie so ausgelegt werden, dass sie mit geringstmöglichem Kraftaufwand die jeweils zugehörigen Elemente antreiben. Dabei ist es auch möglich, den Antriebsmotor 10 der Weblade 13 so anzusteuern, dass er während des Anschlagens eines Schussfadens die Weblade immer mit der gleichen Geschwindigkeit oder mit einer mit der Eingabeeinheit 53 eingegebenen Geschwindigkeit bewegt, unabhängig von der sonstigen Geschwindigkeit der Elemente der Webmaschine, d.h. unabhängig von der sich gegebenenfalls auch ändernden Webgeschwindigkeit, mit der aufeinanderfolgende Schussfäden eingewoben werden. Auf diese Weise kann sichergestellt werden, dass jeder Schussfaden mit der gleichen oder vorgegebenen unterschiedlichen Kraft angeschlagen wird.Since the
Die Fachbildungseinrichtung enthält beispielweise eine Schaftmaschine, oder einen anderen Schaftantrieb, der als Dobby oder Nockenantrieb oder Kurbelantrieb oder Exzenterantrieb odgl. ausgebildet ist. Die Fachbildungseinrichtung kann auch eine Jacquard-Einrichtung sein. Darüber hinaus kann die Fachbildungseinrichtung auch so ausgebildet sein, dass jedem Webschaft ein einzelner Antriebsmotor oder Gruppen von Webschäften jeweils ein Antriebsmotor zugeordnet ist.The shedding device includes, for example, a dobby, or another shaft drive, the like or Dobby or cam drive or crank drive or eccentric drive. is trained. The shedding device may also be a jacquard device. In addition, the shedding device can also be designed so that each weaving shank a single drive motor or groups of Webschäften is associated with a respective drive motor.
Der Steuer- und Regeleinrichtung 48 ist eine Eingabeeinheit 55 zugeordnet, über welche die Daten eingegeben werden können, die benötigt werden, um den Drehwinkelverlauf der imaginären Synchronisationswelle zu bilden. Den Steuer- und Regeleinheiten 49, 51 der Aritriebsmotoren 10, 44 sind Eingabeeinheiten 53, 54 zugeordnet, über die Daten eingegeben werden können, die bestimmen, zu welcher Winkelposition oder Winkelpositionen der imaginären Synchronisationswelle die Antriebsmotoren 10, 44 jeweils synchronisiert sind, d.h. die von diesen angetriebenen Elemente.The
Die Antriebsmotoren 10, 44 können mit einem eigenen Drehwinkelverlauf betrieben werden. Die Antriebsmotoren 10, 44 können mittels der jeweils zugehörigen Steuer- und Regeleinheit 49, 51 in Verbindung mit Signalen der Drehpositionsgeber 50, 52 so betrieben werden, wie dies beispielsweise aus der
Jedes der Elemente und auch jeder der Antriebsmotoren 10, 44 müssen nicht absolut genau zu einer vorgegebenen Drehwinkelposition der imaginären Synchronisationswelle synchronisiert sein. Es reicht aus, wenn sie mit einer relativ geringen Toleranz zu diesen Drehwinkelpositionen der imaginären Synchronisationswelle synchronisiert sind. Dabei ist eine Synchronisation im Allgemeinen ausreichend genau, wenn die Abweichung zu der Drehwinkelposition der imaginären Synchronisationswelle kleiner als 5° ist. Ein Toleranzwert kann für jeden Schusseintrag unterschiedlich festgelegt werden.Each of the elements and also each of the
Jedes Element, beispielsweise die Weblade oder Fachbildungseinrichtungen kann selbstverständlich auch zu mehreren Drehwinkelpositionen der imaginären Synchronisationswelle synchronisiert werden. Eine Synchronisation für die Weblade kann beim Anschlagen beispielsweise bei 360°, beim Beginn eines Schussfadeneintrags beispielsweise bei 80°, und bei Ende eines Schussfadeneintrags beispielsweise bei 240°, synchronisiert werden. Bei diesem Synchronisieren kann vorgesehen werden, dass die Weblade zwischen den Drehwinkelpositionen 80° und 240° im Wesentlichen in ihrer hinteren Position stehen bleibt. Die Fachbildungseinrichtung kann für die Drehwinkelposition des Kreuzens beispielsweise bei 320° und beim Beginn des Schusseintrags beispielweise bei 80° und beim Ende des Schusseintrags beispielsweise bei 240° synchronisiert werden, d.h. während der Zeit, während der das Webfach genügend weit offen bleiben muss.Of course, each element, for example the batten or shedding means, can also be synchronized to a plurality of angular positions of the imaginary synchronization shaft. A synchronization for the sley can be synchronized when striking for example at 360 °, at the beginning of a weft insertion, for example at 80 °, and at the end of a weft insertion, for example at 240 °. In this synchronization can be provided that the batten between the rotational angle positions 80 ° and 240 ° remains substantially in its rear position. The shedding device can be synchronized for the rotational angle position of the crossing, for example at 320 ° and at the beginning of the weft insertion, for example at 80 ° and at the end of the weft insertion, for example at 240 °, i. during the time during which the shed must remain sufficiently wide open.
Wenn das Übertragungsverhältnis zwischen Antriebsmotor und angetriebenem Element eine ganze Zahl ist, ist es ohne weiteres möglich, den Antriebsmotor und nicht das angetriebene Element zu Drehwinkelpositionen der imaginären Synchronisationswelle zu synchronisieren.When the transmission ratio between the drive motor and the driven element is an integer, it is easily possible to synchronize the drive motor and not the driven element to rotational positions of the imaginary synchronization shaft.
Der für die imaginäre Synchronisationswelle gebildete Drehwinkelverlauf kann auf einer konstanten Drehzahl beruhen. Bevorzugt wird vorgesehen, dass der Drehwinkelverlauf über mehrere Schusseinträge festgelegt wird und sich dann jeweils wiederholt. Dabei kann der Drehwinkelverlauf in Funktion von unterschiedlichen, nacheinander einzubringenden Arten von Schussfaden, von aufeinander folgenden Kettfadenbindungen, von der Anzahl der von unten nach oben oder der von oben nach unten zu bewegenden Kettfäden oder in Abhängigkeit von anderen Bedingungen festgelegt werden. Insbesondere wird ein geeigneter Drehwinkelverlauf für die imaginäre Synchronisationswelle für das Starten und Stoppen der Webmaschine festgelegt.The rotational angle curve formed for the imaginary synchronization shaft can be based on a constant speed. It is preferably provided that the rotation angle course is determined over a plurality of weft entries and then repeated in each case. In this case, the rotational angle curve can be determined as a function of different types of weft thread to be introduced in succession, of successive warp thread bindings, of the number of warp threads to be moved from bottom to top or from top to bottom or depending on other conditions. In particular, a suitable rotation angle curve for the imaginary synchronization shaft for starting and stopping the loom is set.
Ebenso kann vorgesehen werden, dass die Drehwinkelpositionen der imaginären Synchronisationswelle variiert werden, zu denen ein Element synchronisiert wird. Wenn beispielsweise ein Drehwinkelverlauf der imaginären Synchronisationswelle für mehrere Schusseinträge festgelegt wird, beispielsweise für drei Schusseinträge, so kann vorgesehen werden, dass die Fachbildungseinrichtung für ein Kreuzen der Kettfäden bei dem ersten Schusseintrag auf 320°, bei dem zweiten Schusseintrag auf 315° und bei einem dritten Schusseintrag auf 310° synchronisiert ist. Danach wiederholt sich der Ablauf.It can also be provided that the rotational angle positions of the imaginary synchronization wave are varied, to which an element is synchronized. If, for example, a rotation angle profile of the imaginary synchronization wave is determined for several weft entries, for example for three weft entries, it can be provided that the shedding device for crossing the warp threads at the first weft insertion at 320 °, at the second weft insertion at 315 ° and at a third Weft insertion is synchronized to 310 °. Thereafter, the process is repeated.
Das erfindungsgemäße Steuern oder Regeln von Antriebsmotoren in Abhängigkeit von dem Drehwinkelverlauf einer imaginären Synchronisationswelle wird in weiterer Ausgestaltung der Erfindung auch zum Antreiben von anderen Elementen ausgenutzt, beispielsweise zum Antreiben eines Tuchaufwickelmotors, eines Motors eines Kanteneinlegers oder einer Kantenbildungseinrichtung oder ähnlicher Einrichtungen. Darüber hinaus kann die Erfindung auch zum Antreiben einer sogenannten Jacquarette eingesetzt werden, d.h. einer verkleinerten Jacquardeinrichtung, die nur eine geringe Anzahl von Kettfäden bedient, beispielsweise 100 Kettfäden, während die übrigen Kettfäden durch Webschäfte oder eine große Jacquardeinrichtung bedient werden.The inventive control or regulation of drive motors in dependence on the rotation angle of an imaginary synchronization shaft is exploited in another embodiment of the invention for driving other elements, for example for driving a cloth winding motor, an engine of an edge inserter or an edge forming device or similar devices. In addition, the invention can also be used for driving a so-called Jacquarette, i. a reduced Jacquardeinrichtung that operates only a small number of warp threads, for example, 100 warp threads, while the remaining warp threads are operated by heddles or a large Jacquardeinrichtung.
