Description

Die Erfindung betrifft einen Antrieb für eine Webmaschine mit einem mittels eines Hauptantriebsmotors antreibbaren Schaltrad, das zwischen wenigstens zwei Schaltstellungen axial verschiebbar ist, das in einer ersten Schaltstellung in Antriebsverbindung mit zwei Gruppen von anzutreibenden Elementen ist und das in einer zweiten Schaltstellung von einer der Gruppen anzutreibender Elemente getrennt ist, und mit einer beim Trennen der Antriebsverbindung zu der einen Gruppe tätigwerdenden Vorrichtung, die die von dem Schaltrad getrennte Gruppe von anzutreibenden Elementen in einer definierten Position hält.The invention relates to a drive for a loom with a drivable by a main drive motor ratchet, which is axially displaceable between at least two switching positions, which is in a first switching position in driving connection with two groups of driven elements and to be driven in a second switching position of one of the groups Elements is separated, and with an acting in disconnecting the drive connection to the one group device that holds the separated of the ratchet group of elements to be driven in a defined position.

Ein Antrieb der Eingangs genannten Art ist aus der EP 0726345 A1 bekannt. Er weist eine im Maschinenrahmen gelagerte Hauptantriebswelle auf, die mittels eines Antriebsmotors über Getriebeelemente, beispielsweise einen Riemenantrieb angetrieben wird. Die Hauptantriebswelle ist mit einem axial verschiebbaren Schaltrad versehen, dass in einer ersten Stellung sowohl in ein erstes Zahnrad für wenigstens den Antrieb einer Weblade als auch in ein zweites Zahnrad für wenigstens den Antrieb von Fachbildungsmitteln eingreift. In der zweiten Schaltstellung greift es nur in eines der beiden Zahnräder ein. Das Schaltrad und die Hauptantriebswelle sind mittels einer Verzahnung drehfest mit einander verbunden, so dass das axial verschiebbare Schaltrad spielfrei in der Hauptantriebswelle in Verbindung steht. Eine spielfreie Verbindung in Drehrichtung ist erforderlich, um das zu übertragenden Antriebsmoment in positiver und negativer Richtung ändern zu können. In der Verbindung zwischen dem Hauptantriebsmotor und der Hauptantriebswelle können eine schaltbare Kupplung und/oder eines schaltbare Bremse integriert sein. Wird der Antrieb für Greiferwebmaschinen eingesetzt, so kann das erste Zahnrad neben der Weblade auch einen Antrieb für die Greifer antreiben. Beim normalen Webbetrieb sowie im langsamen Webbetrieb greift das Schaltrad in beide Zahnräder ein. Bei der sogenannten Schusssuche (Suche eines gebrochenen Schussfadens) greift das Schaltrad nur in das Zahnrad ein, das die Fachbildungsmittel antreibt. Im langsamen Betrieb und bei der Schusssuche wird der Antriebsmotor mit einer gegenüber dem normalen Weben reduzierten Drehzahl angetrieben. Alternativ kann für den langsamen Betrieb und die Schusssuche ein spezieller Kriechgangmotor vorgesehen werden. Beim Trennen der Antriebsverbindung zu einer der Gruppen wird eine Vorrichtung tätig, die mit einem Dorn in einer Aufnahme des Zahnrades eingreift, das von dem Schaltrad getrennt wird, und das zu der Gruppe von Elementen gehörte, deren Antriebsverbindung unterbrochen ist. Die Antriebsverbindung kann somit nur getrennt werden, wenn sich der Dorn und die Aussparung dieses Antriebszahnrades gegenüberstehen.A drive of the type mentioned is from the EP 0726345 A1 known. It has a main drive shaft mounted in the machine frame, which is driven by means of a drive motor via transmission elements, for example a belt drive. The main drive shaft is provided with an axially displaceable ratchet that engages in a first position both in a first gear for at least driving a sley and in a second gear for at least the drive of shedding means. In the second switching position, it only engages in one of the two gears. The ratchet wheel and the main drive shaft are rotatably connected by means of a toothing with each other, so that the axially displaceable ratchet is free of play in the main drive shaft in connection. A play-free connection in the direction of rotation is required in order to change the drive torque to be transmitted in the positive and negative directions. In the connection between the main drive motor and the main drive shaft, a switchable clutch and / or a switchable brake can be integrated. If the drive is used for rapier looms, then the first gear in addition to the batten can also drive a drive for the gripper. In normal weaving operation as well as in slow weaving operation, the ratchet wheel engages in both gears. In the so-called shot search (search of a broken weft thread) the ratchet engages only in the gear one that drives the shedding means. In slow operation and in the shot search of the drive motor is driven with a reduced compared to the normal weaving speed. Alternatively, a special crawler motor can be provided for the slow operation and the shot search. When separating the drive connection to one of the groups, a device is activated which engages with a mandrel in a receptacle of the gear wheel which is separated from the switching wheel and which belonged to the group of elements whose drive connection is interrupted. The drive connection can thus only be separated when facing the mandrel and the recess of this drive gear.

Der Erfindung liegt die Aufgabe zu Grunde, einen Antrieb der Eingangs genannten Art insbesondere für die Schusssuche zu verbessern.The invention is based on the object to improve a drive of the type mentioned above, in particular for the shot search.

Diese Aufgabe wird dadurch gelöst, dass die Vorrichtung ein in ein Zahnrad der von dem Schaltrad getrennten Gruppe von anzutreibenden Elementen eingreifendes Zahnelement besitzt.This object is achieved in that the device has a toothed element engaging in a toothed wheel of the group of elements to be driven that is separated from the indexing wheel.

Die erfindungsgemäße Ausbildung des Antriebs bietet den Vorteil, dass die Antriebsverbindung zwischen dem Schaltrad und einer Gruppe der anzutreibenden Elemente in einer Vielzahl von Stellungen unterbrochen werden kann, wobei die Vielzahl dieser Stellungen unter anderem durch die Anzahl der Zähne des betreffenden Zahnrades bestimmt wird, in die das Zahnelement eingreift. Damit ist es möglich, die Antriebsverbindung in nahezu jeder beliebigen Stellung des Schaltrades zu unterbrechen. Ein derartiger Antrieb ist darüber hinaus kompakt und raumsparend.The inventive design of the drive has the advantage that the drive connection between the ratchet and a group of elements to be driven can be interrupted in a variety of positions, the plurality of these positions being determined, inter alia, by the number of teeth of the respective gear in the the toothed element engages. This makes it possible to interrupt the drive connection in almost any position of the ratchet wheel. Such a drive is also compact and space-saving.

In Ausgestaltung der Erfindung wird vorgesehen, dass das Zahnelement der Vorrichtung einem Antriebszahnrad zugeordnet ist, das in der ersten Schaltstellung des Schaltrades mit dem Schaltrad in Eingriff ist. Die Gruppe der von diesem Antriebszahnrad anzutreibenden Elemente kann in einer Vielzahl von Stellungen fixiert werden.In an embodiment of the invention, it is provided that the toothed element of the device is associated with a drive gear, which is in the first switching position of the ratchet wheel with the ratchet engaged.

Dadurch kann die Vorrichtung mit dem Zahnelement in der Höhe des Schaltrades angeordnet werden. Die Anzahl der Stellungen, in welchen die Antriebsverbindung getrennt werden kann, wird durch die Anzahl der Zähne des Antriebsrades bestimmt. Diese Ausführungsform ermöglicht einen besonders kompakten Aufbau. Darüber hinaus besteht bei dieser Ausführungsform der Vorteil, dass das Antriebsrad, mit welchem das Schaltrad in Eingriff gebracht werden kann, direkt gehalten wird, was für ein Wiedereinkuppeln von Antriebsrad und Schaltrad von Vorteil ist.According to one of the preferred embodiment, the toothed element of the device is in the second switching position of the switching wheel in engagement with the teeth of the drive wheel group to be driven elements which is engaged in the first Schaltradstellung with the ratchet engaged and in the second switching position outside. As a result, the device can be arranged with the toothed element in the height of the switching wheel. The number of positions in which the drive connection can be separated is determined by the number of teeth of the drive wheel. This embodiment allows a particularly compact structure. Moreover, in this embodiment, there is the advantage that the drive wheel, with which the ratchet wheel can be engaged, is held directly, which is advantageous for a re-engagement of drive wheel and ratchet wheel.

Gemäß einer Ausführungsform besitzt die Vorrichtung wenigstens ein Zahnsegment, das den Zähnen eines Zahnrades einer Gruppe der anzutreibenden Elemente zugeordnet ist. Dadurch kann das betreffende Zahnrad in bestimmten Winkelstellungen aritiert und fixiert werden. Die Zähne des Zahnsegments sind zweckmäßiger Weise in Abhängig von den Zähnen des Zahnrades gewählt, so dass ein korrekter Eingriff erzielt wird.According to one embodiment, the device has at least one toothed segment which is associated with the teeth of a toothed wheel of a group of the elements to be driven. This allows the gear in question in certain angular positions aritiert and fixed. The teeth of the toothed segment are appropriately selected depending on the teeth of the gear, so that a correct engagement is achieved.

Gemäß einer Ausführungsform enthält die Vorrichtung ein Zahnelement in Form eines Zahnrades. Falls dieses Zahnrad nicht drehbar montiert ist, kann es die betreffende Gruppe anzutreibender Elemente in vorgegebenen Winkelstellungen fixieren.According to one embodiment, the device includes a toothed element in the form of a toothed wheel. If this gear is not rotatably mounted, it can fix the relevant group to be driven elements in predetermined angular positions.

Bei einer abgewandelten Ausführungsform ist vorgesehen, dass das Zahnrad mit einem Hilfsantrieb verbunden ist, dem eine Steuerung zugeordnet ist, mit der die von dem Schaltrad getrennte Gruppe von anzutreibenden Elementen vor dem Wiederherstellen der Antriebsverbindung mit dem Schaltrad in eine an die Position der anderen Gruppe angepasste Position bringbar ist. Das Wiederherstellen der Antriebsverbindung kann dann erfolgen, ohne dass die Gruppe, deren Antriebsverbindung zu dem Schaltrad nicht unterbrochen war, ihre Position verändert.In a modified embodiment, it is provided that the gear is connected to an auxiliary drive, which is associated with a control, with which separated from the ratchet group of elements to be driven before restoring the drive connection with the ratchet wheel in one adapted to the position of the other group Position can be brought. The restoration of the drive connection can then take place without the group whose drive connection to the ratchet wheel was not interrupted changing its position.

Bei einer Ausführungsform enthält der Antrieb eine Stellvorrichtung um mindestens das erfindungsgemäße Zahnelement und vorzugsweise das Schaltrad zusammen mit dem Zahnelement in axialer Richtung des Schaltrades zwischen der ersten Schaltstellung und der zweiten Schaltstellung zu verschieben. Dadurch ist ein kompakter Aufbau des erfindungsgemäßen Antriebs möglich. Außerdem kann sichergestellt werden, dass das Zahnelement mit dem betreffenden Zahnrad in Eingriff ist, wenn die Antriebsverbindung zwischen diesem Zahnrad und dem Schaltrad getrennt wird.In one embodiment, the drive includes an adjusting device for at least the toothed element according to the invention and preferably the indexing gear to move together with the toothed element in the axial direction of the switching wheel between the first switching position and the second switching position. As a result, a compact construction of the drive according to the invention is possible. In addition, it can be ensured that the toothed element with the respective gear is engaged when the drive connection between this gear and the ratchet wheel is disconnected.

Bei einer Ausführungsform ist vorgesehen, dass dem Schaltrad ein vom dem Hauptantriebsmotor angetriebenes Antriebsrad zugeordnet ist, dass sowohl in der ersten Schaltstellung als auch in der zweiten Schaltstellung mit dem Schaltrad in Eingriff ist.

In a modified embodiment, it is provided that the switching wheel is connected directly to the motor shaft of the main drive motor.

Bei dem in Figur 1 bis 5 dargestellten Antrieb für eine Webmaschine ist eine Hauptantriebswelle 2 mittels Rollenlager 3, 4 in einen Maschinenrahmen 1 gelagert. Auf der Hauptantriebswelle 2 ist ein Schaltrad 5 angeordnet, das mittels eines Antriebsrades 6 und einem als Hauptantriebsmotor 7 dienenden Elektromotor angetrieben ist. Das Schaltrad 5 kann einstückig mit der Hauptantriebswelle sein oder auf dieser angebracht sein.At the in Figure 1 to 5 shown drive for a weaving machine is a main drive shaft 2 by means of roller bearings 3, 4 stored in a machine frame 1. On the main drive shaft 2, a ratchet wheel 5 is arranged, which is driven by means of a drive wheel 6 and serving as a main drive motor 7 electric motor. The ratchet wheel 5 may be integral with or attached to the main drive shaft.

Das Schaltrad 5 greift in ein axial gerichtete Zähne aufweisenden Antriebsrad 9 ein, das mittels einer Welle 10 mit einem oder mehreren angetriebenen Elementen 11 verbunden ist. Die angetriebenen Elemente 11 sind beispielsweise Fachantriebselemente, die aus einer Schaftmaschine, einer Exzentermaschine, einer Jacquardmaschine oder einer anderen Vorrichtung zum Bilden von Webflächen bestehen. Die angetriebenen Elemente 11 können auch andere Vorrichtungen sein, beispielsweise Kanteneinrichtungen oder eine Vorrichtung zum positiven Bewegen eines Streichbaums.The ratchet wheel 5 engages in an axially directed teeth having drive wheel 9, which is connected by means of a shaft 10 with one or more driven elements 11. The driven members 11 are, for example, tray drive members consisting of a dobby, an eccentric machine, a jacquard machine, or other web forming apparatus. The driven elements 11 may also be other devices, such as edging devices or a device for positively moving a coating tree.

In der Schaltstellung nach Figur 1 ist das Schaltrad 5 auch mit einem axial gerichtete Zähne aufweisenden Antriebsrad 12 in Eingriff, das mittels einer Welle 13 mit weiteren angetriebenen Elementen 14 verbunden ist. Diese angetriebenen Elemente 14 sind beispielsweise die Antriebseinrichtungen für eine Weblade und - bei einer Greiferwebmaschine - die Antriebseinrichtungen für Greifer oder Greiferbänder. Die angetriebenen Elemente 14 können darüber hinaus auch andere Vorrichtungen sein, beispielsweise Kanteneinleger, eine Vorrichtung zum Antrieb der Gewebeaufwicklung oder eine Vorrichtung zum Antrieb der Abfallaufwicklung. Bei dem dargestellten Ausführungsbeispiel sind die Hauptantriebswelle 2 und die Wellen 10 und 13 parallel zueinander angeordnet.In the switching position to FIG. 1 the ratchet wheel 5 is also in engagement with an axially directed teeth having drive wheel 12, which is connected by means of a shaft 13 with further driven elements 14. These driven elements 14 are, for example, the drive means for a sley and - in a rapier - the drive means for grippers or gripper bands. The driven elements 14 may also be other devices, for example, edge depositors, a tissue reeling drive device, or a waste rewind drive device. In the illustrated embodiment the main drive shaft 2 and the shafts 10 and 13 are arranged parallel to each other.

Um das mit der Hauptantriebswelle 2 aufzubringende Antriebsdrehmoment zu beschränken, ist bei der dargestellten Ausführungsform der Durchmesser des Schaltrades 5 kleiner gewählt als der Durchmesser der Antriebsräder 9 und 12. Aus dem gleichen Grund ist der Durchmesser des Antriebsrades 6 kleiner als der Durchmesser des Schaltrades 5. Bei dem dargestellten Ausführungsbeispiel ist die Auslegung so getroffen worden, dass die Antriebsräder 9 und 12 eine Umdrehung pro Schusseintrag ausführen.In order to limit the drive torque to be applied with the main drive shaft 2, in the illustrated embodiment the diameter of the ratchet wheel 5 is smaller than the diameter of the drive wheels 9 and 12. For the same reason, the diameter of the drive wheel 6 is smaller than the diameter of the ratchet wheel 5. In the illustrated embodiment, the design has been made so that the drive wheels 9 and 12 perform one revolution per weft insertion.

In der ersten Schaltstellung des Schaltrades 5, die in Figur 1 dargestellt ist, wird die Webmaschine beim Weben von der Hauptantriebswelle 2 angetrieben. In dieser Schaltstellung greift das Schaltrad 5 in beide Antriebsräder 9 und 12 ein, so dass diese Antriebsräder 9 und 12 von der Hauptwelle 2 über das Schaltrad 5 angetrieben werden. Es besteht in dieser Schaltstellung zwischen dem Schaltrad 5 über das Antriebsrad 9 eine Antriebsverbindung zu einer ersten Gruppe anzutreibender Elemente 11 und über das Antriebsrad 12 eine Antriebsverbindung zu einer zweiten Gruppe anzutreibender Elemente 14.In the first switching position of the ratchet wheel 5, the in FIG. 1 is shown, the weaving machine is driven by the main drive shaft 2 during weaving. In this switching position, the ratchet wheel 5 engages in both drive wheels 9 and 12, so that these drive wheels 9 and 12 are driven by the main shaft 2 via the ratchet wheel 5. There is in this switching position between the ratchet wheel 5 via the drive wheel 9, a drive connection to a first group to be driven elements 11 and the drive wheel 12 a drive connection to a second group to be driven elements 14th

Wenn nach einem Webmaschinenstop um eine sogenannte Schusssuche durchzuführen die Antriebsverbindung zwischen der Hauptantriebswelle 2 und den anzutreibenden Elementen 14, insbesondere der Weblade, unterbrochen werden muss, wird die Hauptantriebswelle 2 mitsamt dem Schaltrad 5 durch eine axiales Schieben in die zweite Schaltstellung gebracht, die in Figur 2 dargestellt ist. In dieser Schaltstellung greift das Schaltrad 5 weiterhin in das Antriebsrad 9 ein, so dass die Antriebsverbindung zu den anzutreibenden Elementen 11 bestehen bleibt. Das Schaltrad 5 wird jedoch von dem Antriebsrad 12 getrennt, so dass die Antriebsverbindung zu den anzutreibenden Antriebselementen 14 unterbrochen ist.If, after a weaving machine stop to perform a so-called shot search the drive connection between the main drive shaft 2 and the driven elements 14, in particular the sley, must be interrupted, the main drive shaft 2 is brought together with the ratchet 5 by an axial sliding in the second switching position, in FIG. 2 is shown. In this switching position, the ratchet wheel 5 continues to engage in the drive wheel 9, so that the drive connection to the driven elements 11 remains. However, the ratchet wheel 5 is separated from the drive wheel 12 so that the drive connection to the drive elements 14 to be driven is interrupted.

Das axiale Verschieben des Schaltrades 5 erfolgt mittels einer Stellvorrichtung 8. Die Stellvorrichtung 8 besitzt einen Halter 16, der mit der Hauptantriebswelle 2 zusammen wirkt. Der Halter 16 wird mittels eines Kolbens 17 angetrieben, der in einem Zylinder 18 angeordnet ist. Der Zylinder 18 ist an einer Hydraulik- oder Druckluftversorgung 19 angeschlossen beispielsweise an eine Hydraulikversorgung, die derjenigen entspricht, wie sie in der EP 0 726 345 A1 oder in der EP 0 953 073 A1 erläutert worden ist. Der Halter 16 wird hydraulisch oder pneumatisch zu der Hauptantriebswelle 2 hinbewegt. Um den Halter 16 in die Gegenrichtung zu bewegen, ist bei dem Ausführungsbeispiel eine Rückstellfeder 20 vorgesehen. Bei einer abgewandelten Ausführungsform ist vorgesehen, dass die Stellvorrichtung für jede Bewegungsrichtung eine Kolben- Zylindereinheit aufweist, so dass keine Rückstellfeder benötigt wird. Die Zähne der Verzahnung des Schaltrades 5 sind im Bereich ihrer zu dem Antriebsrad 12 gerichteten Stirneneden 21 bevorzugt angefasst um einerseits das Eingreifen des Schaltrades 5 in das Antriebsrad 12 zu erleichtern und andererseits gegebenenfalls das Antriebsrad 12 beim Einschieben des Schaltrades 5 etwas zu verdrehen. Der erfindungsgemäße Antrieb enthält auch eine Vorrichtung 15, um die erste Gruppe der anzutreibenden Elemente 12, 13 und 14 in der zweiten Schaltstellung, wenn die Antriebsverbindung zu dem Schaltrad 5 getrennt ist, in einer definierten Position zu fixieren. Die Vorrichtung 15 greift mit einem Zahnrad 22 in der zweiten Stellung des Schaltrades 5 in die Zähne des Antriebsrades 12 ein, dass zu dieser Gruppe von anzutreibenden Elementen gehört.The axial displacement of the switching wheel 5 by means of an adjusting device 8. The adjusting device 8 has a holder 16 which is connected to the main drive shaft 2 works together. The holder 16 is driven by means of a piston 17 which is arranged in a cylinder 18. The cylinder 18 is connected to a hydraulic or compressed air supply 19, for example, to a hydraulic supply corresponding to that in the EP 0 726 345 A1 or in the EP 0 953 073 A1 has been explained. The holder 16 is moved hydraulically or pneumatically to the main drive shaft 2. In order to move the holder 16 in the opposite direction, a return spring 20 is provided in the embodiment. In a modified embodiment, it is provided that the adjusting device has a piston-cylinder unit for each direction of movement, so that no return spring is needed. The teeth of the toothing of the ratchet wheel 5 are preferably in the range of their directed to the drive wheel 12 Stirneneden 21 touched on the one hand to facilitate the engagement of the ratchet wheel 5 in the drive wheel 12 and on the other hand optionally the drive wheel 12 during insertion of the ratchet wheel 5 something to twist. The drive according to the invention also includes a device 15 to fix the first group of elements to be driven 12, 13 and 14 in the second switching position when the drive connection to the ratchet wheel 5 is separated, in a defined position. The device 15 engages with a gear 22 in the second position of the ratchet wheel 5 in the teeth of the drive wheel 12 that belongs to this group of elements to be driven.

In der zweiten Schaltstellung (Figur 2) bleibt die Antriebsverbindung zwischen dem Antriebsrad 6 und dem Schaltrad 5 sowie die Antriebsverbindung zwischen dem Schaltrad 5 und dem Antriebsrad 9 erhalten.In the second switching position ( FIG. 2 ), the drive connection between the drive wheel 6 and the ratchet wheel 5 and the drive connection between the ratchet wheel 5 and the drive wheel 9 is maintained.

Die Vorrichtung 15 besitzt ein Zahnrad 22, das in die Zähne des Antriebsrades 12 eingreifen kann und das auf dem bereits genannten Halter 16 angebracht ist. Das Zahnrad 22 wird ebenfalls mittels der Stellvorrichtung 8, die auf den Halter 16 wirkt, zusammen mit dem Schaltrad 5 in axialer Richtung zwischen der ersten Stellung und der zweiten Stellung verschoben. Der Verschiebeantrieb erfolgt in einer Richtung mittels des Kolbens 17 und in die andere Richtung mittels der Rückstellfeder 20. Zum Erleichtern des Einführens der Zähne des Zahnrades 22 in die Zähne des Antriebsrades 12 sind die Zähne des Zahnrades 22 und/oder die diesen zugewandten Bereiche der Zähne des Antriebsrades 12 angefasst. Die Anordnung des Zahnrades 22 an dem Halter 16 und damit die Ausrichtung in axialer Richtung zu dem Schaltrad 5 ist so gewählt, dass die Zähne des Zahnrades 22 bereits in die Zähne des Antriebsrades 12 eingreifen, bevor das Schaltrad 5 sich völlig von dem Antriebsrad 12 getrennt hat, d.h. bevor das Schaltrad 5 die zweite Schaltstellung gemäß Figur 2 erreicht hat. Auf diese Weise wird sichergestellt, dass das Antriebsrad 12 mittels des Zahnrades 22 schon fixiert ist, wenn das Schaltrad 5 und das Antriebsrad 12 getrennt werden.The device 15 has a gear 22 which can engage in the teeth of the drive wheel 12 and which is mounted on the aforementioned holder 16. The gear 22 is also displaced by means of the adjusting device 8, which acts on the holder 16, together with the ratchet wheel 5 in the axial direction between the first position and the second position. The displacement drive takes place in one direction by means of the piston 17 and in the other direction by means of the return spring 20. To facilitate the insertion of the teeth of the gear 22 in the teeth of the drive wheel 12 are the Teeth of the gear 22 and / or these areas facing the teeth of the drive wheel 12 touched. The arrangement of the gear 22 on the holder 16 and thus the orientation in the axial direction to the ratchet wheel 5 is selected so that the teeth of the gear 22 already engage in the teeth of the drive wheel 12 before the ratchet wheel 5 completely separated from the drive wheel 12 has, ie before the ratchet wheel 5, the second switching position according to FIG. 2 has reached. In this way it is ensured that the drive wheel 12 is already fixed by means of the gear 22 when the ratchet wheel 5 and the drive wheel 12 are disconnected.

Der Hauptantriebsmotor 7 ist ein vorzugsweise bezüglich Drehzahl und/oder Winkelstellung und/oder Antriebsmoment und/oder Drehrichtung regelbarer Elektromotor. Die Regelung erfolgt über eine Steuereinheit 24, die Start und Stop der Webmaschine, Kriechgang oder Bewegung für die Schusssuche und das Trennen zwischen Schaltrad 5 und Antriebsrad 12 in einer gewünschten Winkelstellung sowie das Wiedereinkuppeln der beiden in einer gewünschten Winkelstellung bestimmt. Der Hauptantriebsmotor 7 ist vorzugsweise ein schaltbarer Reluktanzmotor, der den Vorteil aufweist, das er in bestimmten Positionen elektrisch gebremst werden kann. In den Hauptantriebsmotor 7 kann unter Umständen auch eine schaltbare Bremse eingebaut werden, die zugeschaltet wird, wenn der Hauptantriebsmotor 7 in einer bestimmten Winkelstellung angehalten werden soll. Eine derartige Bremse wird vorzugsweise durch Federn in den gebremsten Zustand überführt und durch elektromagnetische Kräfte gelöst. Auf diese Weise kann die Webmaschine bei einem Ausfall der Stromversorgung im gebremsten Zustand gehalten werden.The main drive motor 7 is a preferably with respect to speed and / or angular position and / or drive torque and / or direction of rotation controllable electric motor. The control is carried out via a control unit 24, the start and stop of the weaving machine, crawl or movement for the shot search and the separation between the ratchet wheel 5 and drive wheel 12 in a desired angular position and the re-engagement of the two determined in a desired angular position. The main drive motor 7 is preferably a switchable reluctance motor, which has the advantage that it can be electrically braked in certain positions. Under certain circumstances, a switchable brake can be installed in the main drive motor 7, which is switched on when the main drive motor 7 is to be stopped in a specific angular position. Such a brake is preferably transferred by springs in the braked state and released by electromagnetic forces. In this way, the loom can be maintained in the case of a power failure in the braked state.

Wie das in Figur 3 und 4 dargestellt ist, enthält der Antrieb einen Winkelgeber 23. Dieser Winkelgeber 23 ist bei dem dargestellten Ausführungsbeispiel mechanisch der Welle 10 des Antriebsrades 9 zugeordnet. Er ist an die Steuereinheit 24 angeschlossen. Mit diesem Winkelgeber 23 wird die Winkelstellung des Antriebsrades 9 und somit auch die Winkelstellung der über das Schaltrad 5 mit der Hauptantriebswelle 2 ständig in Verbindung stehenden Hauptantriebswelle 2 bestimmt. Die Winkelstellung der Hauptantriebswelle 2 ist sowohl für das Einkuppeln und Trennen von Schaltrad 5 und Antriebsrad 12 wichtig als auch für das Einkuppeln und Trennen von Zahnrad 22 und Antriebsrad 12.Like that in FIG. 3 and 4 is shown, the drive includes an angle encoder 23. This angle sensor 23 is mechanically associated with the shaft 10 of the drive wheel 9 in the illustrated embodiment. It is connected to the control unit 24. With this angle encoder 23, the angular position of the drive wheel 9 and thus also the angular position of the main drive shaft 2 via the ratchet wheel 5 with the main drive shaft 2 is continuously determined. The angular position of the main drive shaft 2 is both for the engagement and separation of ratchet 5 and drive wheel 12 important as well as for the engagement and separation of gear 22 and drive wheel 12th

Die Signale des Winkelgebers 23 werden von der Steuereinheit 24 in Bezug zur Winkelstellung der Hauptantriebswelle 2 gesetzt. Hierzu wird beispielsweise die Webmaschine in die Anschlagsposition gebracht. Die in dieser Position vom Winkelgeber 23 gemessene Winkelstellung wird als Nullstellung der Hauptantriebswelle 2 in der Steuereinheit 24 abgespeichert. Jeder andere vom Winkelgeber 23 gemessene Winkelposition kann dann über die Steuereinheit 24 in die Winkelstellung der Hauptantriebswelle 2 umgerechnet werden. Es werden die Winkelstellungen der Hauptantriebswelle 2 oder die Winkelstellungen des Antriebsrades 9 in der Steuereinheit 24 gespeichert, bei welchen die Zähne des Zahnrades 22 in die Zähne des Antriebsrades 12 eingeschoben werden können, d.h. wenn sich die Zähne und Zahnlücken gegenüberstehen. Vor dem axialen Verschieben des Zahnrades 22 und des Schaltrades 5 wird die Hauptantriebswelle 2 in eine Winkelstellung gebracht, in der die Zähne des Zahnrades 22 zwischen die Zähne des Antriebsrades 12 geschoben werden können. Die Zähne des Antriebsrades 12 müssen beim Trennen von Schaltrad 5 und Antriebsrad 12 so angeordnet sein, dass die Zähne des Zahnrades 22 zwischen die Zähne des Antriebsrades 12 eingreifen können. Falls das Antriebsrad 12 bei einem Beispiel 112 Zähne besitzt, kann das Zahnrad 22 in 112 verschiedenen Winkelpositionen des Antriebsrades 12 in das Antriebsrad 12 eingeschoben werden. Somit ist in 112 verschiedenen Positionen eine Schusssuche möglich. Selbstverständlich müssen nicht alle möglichen Winkelpositionen verwendet werden. Beispielsweise können andere Einschränkungen eine Schusssuche in bestimmten Winkelpositionen verhindern.The signals of the angle encoder 23 are set by the control unit 24 with respect to the angular position of the main drive shaft 2. For this purpose, for example, the weaving machine is brought into the stop position. The angular position measured in this position by the angle encoder 23 is stored as a zero position of the main drive shaft 2 in the control unit 24. Any other angular position measured by the angle encoder 23 can then be converted via the control unit 24 into the angular position of the main drive shaft 2. It stores the angular positions of the main drive shaft 2 or the angular positions of the drive wheel 9 in the control unit 24, in which the teeth of the gear 22 can be inserted into the teeth of the drive wheel 12, i. when the teeth and tooth spaces are facing each other. Before the axial displacement of the gear 22 and the ratchet wheel 5, the main drive shaft 2 is brought into an angular position in which the teeth of the gear 22 between the teeth of the drive wheel 12 can be pushed. The teeth of the drive wheel 12 must be so arranged during the separation of ratchet wheel 5 and drive wheel 12 that the teeth of the gear 22 between the teeth of the drive wheel 12 can engage. If the drive wheel 12 has 112 teeth in one example, the gear 22 may be inserted into the drive wheel 12 at 112 different angular positions of the drive wheel 12. Thus, in 112 different positions a shot search is possible. Of course, not all possible angular positions need to be used. For example, other constraints may prevent a shot search in certain angular positions.

Beim Wiedereinkuppeln von Schaltrad 5 und Antriebsrad 12 müssen die Zähne des Antriebsrades 12 ebenfalls so angeordnet sein, dass die Zähne des Schaltrades 5 zwischen sie eingreifen können. Hierzu kann das Schaltrad 5 mittels des Antriebsmotors 7 in die erforderliche Position gebracht werden, in der die Zähne des Schaltrades 5 in die Zähne des Antriebsrades 12 einschoben werden können. Die Feststellung der Winkelpositionen der Hauptantriebswelle 2 mittels des Winkelgebers 23 und der Steuereinheit 24 ist für den regelbaren Antriebsmotor 7 auch als Rückkopplung zur Regelung der Winkelstellung und/oder der Drehzahl und/oder des Antriebsmomentes dieses Antriebsmotors 7 wichtig.When re-engaging ratchet wheel 5 and drive wheel 12, the teeth of the drive wheel 12 must also be arranged so that the teeth of the ratchet wheel 5 can intervene between them. For this purpose, the ratchet 5 can be brought by means of the drive motor 7 in the required position in which the teeth of the ratchet wheel 5 in the teeth of the drive wheel 12th can be inserted. The determination of the angular positions of the main drive shaft 2 by means of the angle sensor 23 and the control unit 24 is important for the controllable drive motor 7 as feedback for controlling the angular position and / or the rotational speed and / or the drive torque of this drive motor 7.

Zusätzlich kann eine Kontrollvorrichtung dem Antriebsrad 12 zugeordnet werden, um zu Überwachen, ob bei der gewünschten Winkelstellung eingekuppelt wird. Beispielsweise kann dem Schaltrad 5 ein berührungsloser Endschalter 25 zugeordnet werden, der überwacht, ob das Zahnrad 22 in das Antriebsrad 12 eingreift, wenn sich das Zahnrad 22 in der Position gemäß Figur 2 befindet. Gemäß der nicht dargestellten Abwandlung kann ein berührungsloser Endschalter 25 auch dem Zahnrad 22 oder der Halterung 16 zugeordnet sein. Das Signal des berührungslosen Endschalters 25, das angibt, das sich das Zahnrad 22 in der richtigen Position befindet, kann dazu verwendet werden, um den Beginn der Schusssuche freizugeben und/oder um zu verhindern, dass die Steuereinheit 24 die Webmaschine mit Normalgeschwindigkeit startet. Falls sich das Zahnrad 22 oder das Schaltrad 5 in der Stellung nach Figur 1 befinden, kann das von dem Endschalter 25 dann gegebene Signal dazu verwendet werden, um mittels der Steuereinheit 24 den Start der Webmaschine mit Normalgeschwindigkeit freizugeben.In addition, a control device may be associated with the drive wheel 12 to monitor whether it is engaged at the desired angular position. For example, the shift wheel 5, a non-contact limit switch 25 are assigned, which monitors whether the gear 22 engages the drive wheel 12 when the gear 22 in the position according to FIG. 2 located. According to the modification, not shown, a non-contact limit switch 25 may also be assigned to the gear 22 or the holder 16. The non-contact limit switch 25 signal, indicating that the gear 22 is in the correct position, may be used to enable the start of the shot search and / or to prevent the controller 24 from starting the loom at normal speed. If the gear 22 or the ratchet 5 in the position after FIG. 1 can then be used by the limit switch 25 given signal to enable by means of the control unit 24, the start of the loom at normal speed.

Wenn eine Schusssuche durchgeführt wird, wird die Stellvorrichtung 8 so angesteuert, dass das Schaltrad 5 in die Schaltstellung gemäß Figur 2 verschoben wird, in welcher das Schaltrad 5 von dem Antriebsrad 12 und damit mindestens von dem Antrieb der Weblade getrennt ist. Die Antriebsverbindung zu dem Antriebsrad 9 und damit zum Antrieb der Fachbildungsmittel bleibt bestehen. Zusätzlich greift das Zahnrad 22 in das Antriebsrad 12 ein, so dass das Antriebsrad 12 in einer Stellung fixiert wird, die mittels des Zahnrades 22 vorgegeben ist. Danach betreibt die Steuereinheit 24 den Antriebsmotor so, dass die Schusssuche bei reduzierter Geschwindigkeit ausgeführt wird. Dabei wird das Antriebsrad 9 so lange angetrieben, bis ein Schussfaden von den Fachbildungsmitteln freigelegt worden ist. Danach wird der Antriebsmotor 7 wieder so angesteuert, dass sich die Hauptantriebswelle 2 wieder in einer über den Winkelgeber 23 vorgegebenen Stellung befindet, beispielsweise in der Winkelstellung, in der die Hauptantriebswelle 2 vor dem Durchführen der Schusssuche war. In dieser Winkelstellung wird das Schaltrad 5 wieder mit dem Antriebsrad 12 in Eingriff gebracht und das Zahnrad 22 von dem Antriebsrad 12 getrennt, indem das Schaltrad 5 axial mittels der Stellvorrichtung 8 in die in Figur 1 dargestellte Schaltstellung zurückgebracht wird. Anstelle der Winkelposition in welcher die Trennung von Schaltrad und Antriebsrad erfolgte, kann auch für das Wiedereinkuppeln von den Steuereinheit 24 eine andere Winkelposition vorgegeben werden. Danach kann der normale Webprozess wieder gestartet werden.If a gun search is performed, the adjusting device 8 is driven so that the switching wheel 5 in the switching position according to FIG. 2 is shifted, in which the ratchet wheel 5 is separated from the drive wheel 12 and thus at least from the drive of the batten. The drive connection to the drive wheel 9 and thus to drive the shed forming means remains. In addition, the gear 22 engages the drive wheel 12, so that the drive wheel 12 is fixed in a position which is predetermined by means of the gear 22. Thereafter, the control unit 24 operates the drive motor so that the shot search is performed at a reduced speed. In this case, the drive wheel 9 is driven until a weft thread has been exposed by the shedding means. Thereafter, the drive motor 7 is again driven so that the main drive shaft 2 again in one is on the angle encoder 23 predetermined position, for example in the angular position in which the main drive shaft 2 was prior to performing the gun search. In this angular position, the ratchet wheel 5 is again brought into engagement with the drive wheel 12 and the gear 22 separated from the drive wheel 12 by the ratchet wheel 5 axially by means of the adjusting device 8 in the in FIG. 1 shown switching position is returned. Instead of the angular position in which the separation of ratchet wheel and drive wheel was carried out, a different angular position can also be specified for the re-engagement by the control unit 24. Afterwards the normal weaving process can be started again.

Bei dem Ausführungsbeispiel nach Figur 6 ist der Halter 16 der Vorrichtung 15 nicht mit einem vollständigen Zahnrad 22 versehen, sondern nur mit einem Zahnsegment 26, das als Teil eines Zahnrades gestaltet ist. Dieses Zahnsegment 26 greift entsprechend dem Zahnrad 22 in die Zähne des Antriebsrades 12 ein. In der einfachsten Ausführung ist die Vorrichtung nur mit einem Zahnradelement versehen, dass nur einen einzigen Zahn bildet, der zwischen zwei Zähne des Antriebsrades 12 eingreift.According to the embodiment FIG. 6 the holder 16 of the device 15 is not provided with a complete gear 22, but only with a sector gear 26 which is designed as part of a gear. This sector gear 26 engages according to the gear 22 in the teeth of the drive wheel 12 a. In the simplest embodiment, the device is provided only with a gear element that forms only a single tooth, which engages between two teeth of the drive wheel 12.

Bei dem Ausführungsbeispiel nach Figur 7, ist die Hauptantriebswelle 2, die das Schaltrad 5 aufweist und mittels Lagern 3 und 4 im Maschinenrahmen 1 gelagert ist, die Motorwelle eines Antriebsmotors 7. Die Hauptantriebswelle 2 ist entsprechend der Beschreibung der EP 0953073 A1 ausgeführt und angeordnet. Die Beschreibung der EP 0953073 A1 dient als Bestandteil der vorliegenden Patentanmeldung. Bei diesem Ausführungsbeispiel wird das Schaltrad 5 direkt von dem Hauptantriebsmotor 7 angetrieben.According to the embodiment FIG. 7 , The main drive shaft 2, which has the ratchet wheel 5 and is supported by bearings 3 and 4 in the machine frame 1, the motor shaft of a drive motor 7. The main drive shaft 2 is according to the description of EP 0953073 A1 executed and arranged. The description of EP 0953073 A1 serves as part of the present patent application. In this embodiment, the ratchet wheel 5 is driven directly by the main drive motor 7.

Bei dem Ausführungsbeispiel nach Figur 8 enthält die Vorrichtung 15 einen Antrieb 27 für das Zahnrad 22. Dieser Antrieb 27 enthält einen Antriebsmotor 28, der auf dem Halter 16 angebracht ist und der mittels der Steuereinheit 24 geschaltet werden kann. Der Antriebsmotor 28 kann beispielsweise ein Hydraulikmotor oder ein Schrittmotor sein. Bei diesem Ausführungsbeispiel ist es möglich, dass Antriebsrad 12 und damit die zugehörige Gruppe anzutreibender Elemente 14 anzutreiben, während sie vom Schaltrad 5 und der Hauptantriebswelle 2 getrennt sind. Selbstverständlich müssen dabei Maßnahmen getroffen werden, wie beispielsweise die Verwendung eines zusätzlichen Winkelgebers 29 für die Bestimmung der Winkelposition des Zahnrades 22, um einen Abgleich der Winkelstellung des Zahnrades 22 mit der vom Winkelgeber 23 erfassten Winkelstellung des Antriebsrades 9 mittels der Steuereinheit 24 vorzunehmen und entsprechend den Antriebsmotor 28 in eine Winkelstellung des Zahnrades 22 zu bringen, die an die Winkelstellung des Antriebsrades 9 angepasst ist, damit das Schaltrad 5 wieder in eine bestimmten Winkelstellung in das Antriebsrad 12 eingreift, so dass die Antriebsräder 9 und 12 der beiden Gruppen von anzutreibenden Elementen in einer geeigneten Winkelstellung wieder miteinander gekuppelt sind.According to the embodiment FIG. 8 The device 15 includes a drive 27 for the gear 22. This drive 27 includes a drive motor 28 which is mounted on the holder 16 and which can be switched by means of the control unit 24. The drive motor 28 may be, for example, a hydraulic motor or a stepper motor. In this embodiment, it is possible to drive the drive wheel 12 and thus the associated group of elements to be driven 14, while from the ratchet wheel 5 and the main drive shaft 2 are separated. Of course, measures must be taken, such as the use of an additional angle sensor 29 for determining the angular position of the gear 22 to make an adjustment of the angular position of the gear 22 with the angle encoder 23 detected by the angular position of the drive wheel 9 by means of the control unit 24 and accordingly To bring drive motor 28 in an angular position of the gear 22, which is adapted to the angular position of the drive wheel 9 so that the ratchet wheel 5 engages again in a certain angular position in the drive wheel 12, so that the drive wheels 9 and 12 of the two groups of elements to be driven in a suitable angular position are coupled together again.

Bei dem Ausführungsbeispiel nach Figur 9 ist eine eigene Stellvorrichtung 8 zum Verschieben des Schaltrades 5 und eine eigene Stellvorrichtung 30 für das Verschieben des Zahnrades 22 vorgesehen. Die beiden Stellvorrichtungen 8, 30 sind im wesentlichen gleich ausgebildet und besitzen einen Kolben 17, einen Zylinder 18 und eine Rückstellfeder 31. Das Rückstellen der Stellvorrichtung 30 erfolgt ausschließlich mit der Hilfe der Rückstellfeder 31. Die Stellvorrichtungen 8, 30 werden vorzugsweise so gesteuert, dass das Zahnrad 22 in das Antriebsrad 12 eingreift, bevor das Schaltrad 5 und das Antriebsrad 12 vollständig getrennt werden. Ebenso erfolgt die Steuerung so, dass das Zahnrad 22 erst von dem Antriebsrad 12 getrennt wird, nachdem das Schaltrad 5 wieder mit dem Antriebsrad 12 in Eingriff ist. Das Zahnrad 22 greift somit nicht erst in das Antriebsrad 12 ein, wenn sich das Schaltrad 5 in der zweiten Schaltposition befindet, sondern bereits dann, wenn sich das Schaltrad 5 noch in der ersten Schaltstellung befindet.According to the embodiment FIG. 9 is a separate actuator 8 for moving the ratchet wheel 5 and a separate actuator 30 for the displacement of the gear 22 is provided. The two adjusting devices 8, 30 are formed substantially the same and have a piston 17, a cylinder 18 and a return spring 31. The return of the actuator 30 is carried out exclusively with the aid of the return spring 31. The adjusting devices 8, 30 are preferably controlled so that the gear 22 engages the drive wheel 12 before the ratchet wheel 5 and the drive wheel 12 are completely separated. Likewise, the control is performed so that the gear 22 is only separated from the drive wheel 12 after the ratchet wheel 5 is again in engagement with the drive wheel 12. The gear 22 thus engages not only in the drive wheel 12, when the ratchet wheel 5 is in the second switching position, but already when the ratchet wheel 5 is still in the first switching position.

Bei dem Ausführungsbeispiel nach Figur 10 ist das Schaltrad 5 drehbar auf einer Achse 2' gelagert, die zwar verschiebbar jedoch nicht drehbar in Axialführungen 32, 33 gelagert ist. Das Zahnrad 22 ist drehfest auf der Achse 2' angeordnet und mit dieser Achse 2' axial verschiebbar. Wenn die Achse 2' von der Stellvorrichtung 8 in axialer Richtung aus der ersten Schaltstellung entsprechend Figur 10 in eine zweite Schaltstellung verschoben wird, so greift das Zahnrad 22 in ein Drehfest mit der Welle 13 verbundenes Zahnrad 34 ein. Das Zahnrad 22 sichert somit bei einem Eingriff in das Zahnrad 34 die Drehwinkelposition der Welle 13 und damit der anzutreibenden Elemente 14. Bei einer abgewandelten Ausführungsform wird vorgesehen, dass das Zahnrad 22 in ein Zahnrad eingreift, dass nicht wie das Zahnrad 34 auf der Welle 13 drehfest angeordnet ist, sondern über eine Getriebestufe drehfest mit dem Antriebsrad 12 verbunden ist.According to the embodiment FIG. 10 the ratchet wheel 5 is rotatably mounted on an axis 2 ', which is displaceable, but not rotatably mounted in axial guides 32, 33. The gear 22 is rotatably mounted on the axis 2 'and axially displaceable with this axis 2'. When the axis 2 'of the adjusting device 8 in the axial direction from the first switching position accordingly FIG. 10 is shifted in a second switching position, the gear engages 22 in a rotationally fixed to the shaft 13 connected gear 34. The gear 22 thus ensures upon engagement with the gear 34, the rotational angular position of the shaft 13 and thus the driven elements 14. In a modified embodiment, it is provided that the gear 22 engages a gear that does not like the gear 34 on the shaft 13th is arranged rotationally fixed, but rotatably connected via a gear stage with the drive wheel 12 is connected.

Bei dem Ausführungsbeispiel nach Figur 11 ist die Welle 2 oder Achse 2' entsprechend dem.Ausführungsbeispiel nach Figur 10 axial verschiebbar jedoch drehfest in den Axialführungen 32, 33 geführt. Das Schaltrad 5 ist mittels nicht dargestellten Lagern drehbar auf der Achse 2' gelagert. Im axialen Abstand zum dem Schaltrad 5 ist auf der Achse 2' ein Zahnrad 22 fest angeordnet. Wenn die Achse 2' zusammen mit dem Schaltrad 5 und dem Zahnrad 22 verschoben wird, so greift zuerst das Zahnrad 22 in das Antriebsrad 12 ein, wonach das Schaltrad 5 durch weiteres axiales Schieben von diesem Antriebsrad 12 getrennt wird. Entsprechend greift bei einem Wiedereinkuppeln bereits das Schaltrad 5 in das Antriebsrad 12 ein, bevor eine Trennung von Zahnrad 22 und Antriebsrad 12 erfolgt.According to the embodiment FIG. 11 is the shaft 2 or axis 2 'according to the .Eusführungsbeispiel according to FIG. 10 axially displaceable but rotationally fixed in the axial guides 32, 33 out. The ratchet 5 is rotatably supported by means not shown bearings on the axis 2 '. At an axial distance to the ratchet wheel 5, a gear 22 is fixedly arranged on the axle 2 '. When the axis 2 'is displaced together with the ratchet wheel 5 and the gear 22, so first engages the gear 22 in the drive wheel 12, after which the ratchet wheel 5 is separated by further axial sliding of this drive wheel 12. Accordingly engages in a re-engagement already the ratchet wheel 5 in the drive wheel 12, before a separation of gear 22 and drive wheel 12 takes place.

Die Erfindung ist nicht auf die dargestellten und beschriebenen Ausführungsbeispiele beschränkt. Insbesondere sind Kombinationen zwischen den Ausführungsbeispielen möglich.The invention is not limited to the illustrated and described embodiments. In particular, combinations between the embodiments are possible.
