Abstract

The rotary drive for the reed support, at a loom, has the reed support shaft (4) as a component part of the electromotor (1) direct rotary drive system. It has a stator and, selectively, an inner rotor or an outer rotor. The reed support shaft is keyed against rotation in the loom, to form the stator of the drive. The outer rotor is formed by a carrier (7) of the reed support (2) around the stator. The reed support shaft can form the inner rotor, with a keyed bond to at least one support for the reed (3). The stator can have a component which grips around the inner rotor at least partially, carried in a keyed mounting at the loom. The direct rotary drive can rotate in both directions. The reed support shaft can be a component part of an electromagnetic linear direct drive. The reed support shaft is held in a keyed fit at suitable points across the loom, so that at least one reed support is a permanent magnet secondary component of a linear drive with parallel coil primary components held by a suitable loom section, in a force fit with the reed support shaft. The reed support shaft can be held in rotary mountings at suitable points, to rotate around its longitudinal axis (4A). At least one reed support is a primary component of the linear drive and is linked to the reed support shaft, Secondary components, parallel to the primary components, are at the fixed section. At least one reed support is a double-sided secondary component. Each secondary component has an associated primary component. The direction of the linear drive is reversible. The primary and secondary components, together, can form a disk armature motor. A number of direct rotary or linear drives are deployed across the loom width, composed of identical component groups for each type. At least one motor is fitted with a resolver. One drive can be used for a forward movement, and another drive for a reverse movement of the reed support, or the drives give a reciprocating to and fro movement to the reed.

Description

Die Erfindung betrifft einen Drehantrieb für die Webblattstütze einer Webmaschine nach den Merkmalen des Oberbegriffs der Patentansprüche 1 und 5.The invention relates to a rotary drive for the reed support of a weaving machine according to the Features of the preamble of claims 1 and 5.

Allgemein bekannt in Webmaschinen ist, dass der Antrieb der das Webblatt tragenden Blattstütze von dem Hauptantrieb der Webmaschine über geeignete getriebliche Mittel abgeleitet wird. Dabei erweist sich bei Webmaschinen, die den neuestens Stand der Technik repräsentieren, die starre Kopplung zwischen dem Hauptantrieb respektive der Hauptantriebswelle und der Blattstütze immer mehr als Einschränkung für den Webbetrieb, weil eine derartige Kopplung Nachteile der Gestalt mit sich bringt, dass eine Änderung des Schwenkwinkels der Blattstütze oder des Webblattes ohne kostenaufwendige Maßnahmen nicht möglich ist.It is generally known in weaving machines that the drive of the reed is carried Blade support from the main drive of the weaving machine via suitable gear means is derived. It proves itself in weaving machines that use the latest technology represent the rigid coupling between the main drive and the Main drive shaft and the blade support more and more as a restriction for weaving, because such a coupling has disadvantages of the shape that a change of the Swivel angle of the leaf support or reed without costly measures not possible.

Eine solche kostenaufwendige Maßnahme zur Änderung des Schwenkwinkels eines Webblattes geht z.B. aus der EP 0 892 100 A1 hervor.Such an expensive measure to change the pivot angle of a Webblatt goes e.g. from EP 0 892 100 A1.

Die EP 0 892 100 A1 offenbart eine Vorrichtung zur Änderung der Anschlagstellung eines Webblattes in einer Webmaschine.EP 0 892 100 A1 discloses a device for changing the stop position of a Reeds in a weaving machine.

Der Antrieb der Blattstütze (Weblade) ist vom Hauptantrieb der Webmaschine abgeleitet.The drive of the blade support (weaving drawer) is derived from the main drive of the weaving machine.

Die Blattstütze ist bekanntermaßen zur Ausführung einer oszillierenden hin- und hergehenden Grundbewegung um eine Schwenkachse schwenkbar, wobei ein Antriebsorgan über getriebliche Mittel mit einer in der Blattstütze vorhandenen Schwenkachse wirkverbunden ist. Das Webblatt soll also zusätzlich zur Grundbewegung in der Lage sein, z.B. bei der Herstellung von Frottier, seine Anschlagstellung zu ändern.The blade support is known to perform an oscillating back and forth basic movement pivotable about a pivot axis, a drive member via gear means with a pivot axis present in the blade support is connected. In addition to the basic movement, the reed should also be able to e.g. when making terry towels, to change its stop position.

Der Antrieb zur Ausführung der Grundbewegung der Blattstütze erfolgt in bekannter Weise über eine Wirkverbindung mit dem Hauptantrieb der Webmaschine.The drive for executing the basic movement of the leaf support is carried out in a known manner via an active connection with the main drive of the weaving machine.

Bekannt ist aus der EP 0 440 579 B1 ein Antriebsystem für die ein Webblatt tragende Blattstüzte, welches Antriebsystem unabhängig von dem Hauptantrieb der Webmaschine wirksam ist.From EP 0 440 579 B1 a drive system for the one carrying a reed is known Blade support, which drive system is independent of the main drive of the weaving machine is effective.

Das Antriebsystem besteht aus Mitteln zu Übertragung einer variablen Drehzahl eines Elektromotors auf die Welle der das Webblatt tragenden Blattstütze, wobei der Motor von einem Regler zum Verändern der Drehzahl gesteuert wird.The drive system consists of means for transmitting a variable speed Electric motor on the shaft of the reed supporting the reed, the motor from a controller for changing the speed is controlled.

Die Übertragung der Antriebsleistung des Elektromotors auf die Blattstützwelle bedarf also eines Antriebsystems, z.B. in Gestalt von wenigstens einem Koppelgetriebe oder einem Exzentergetriebe oder eines Riementriebes.The transmission of the drive power of the electric motor to the blade support shaft therefore requires a drive system, e.g. in the form of at least one coupling gear or one Eccentric gear or a belt drive.

Derartige Antriebsysteme erfordern einen entsprechenden Bauraum innerhalb der Webmaschine.Such drive systems require a corresponding space within the Weaving machine.

Die Antriebsysteme sind außerdem verschleissanfällig und wartungsaufwendig.The drive systems are also susceptible to wear and maintenance.

Ferner ist aus der DE 198 21 094 A1 eine Webmaschine bekannt, deren Webblatt mittels eines elektromagnetischen Linearantriebs in eine gesteuerte, hin- und hergehende Bewegung versetzt werden soll.Furthermore, a weaving machine is known from DE 198 21 094 A1, the weaving reed of which of an electromagnetic linear drive in a controlled, reciprocating movement to be moved.

Zu diesem Zwecke greift an der das Webblatt tragenden Blattstütze ein Pleuel an.For this purpose, a connecting rod engages the leaf support carrying the reed.

Das Pleuel und ein Elektromagnet bilden dabei den elektromagnetischen Linearantrieb für die Blattstütze bzw. das Webblatt aus.The connecting rod and an electromagnet form the electromagnetic linear drive for the Leaf support or the reed.

Ein derartiger Antrieb erlaubt, sowohl den Schwenkwinkel der Blattstütze beliebig einzustellen, und zwar unabhängig vom Hauptantrieb der Webmaschine, als auch die Blattanschlagsfrequenz den Erfordernissen auf einfache Weise anzupassen.Such a drive allows both the pivot angle of the blade support as desired adjust, regardless of the main drive of the loom, as well as the Blade stroke frequency can be easily adapted to the requirements.

Neben den unbestreitbaren Vorteilen besitzt der Gegenstand gemäß der DE 198 21 094 A1 nicht unwesentliche Nachteile.In addition to the undeniable advantages, the object according to DE 198 21 094 A1 not insignificant disadvantages.

Das Pleuel stellt als Kontruktionselement eine kritische Lösung dar, weil seine Anbindung an die Blattstütze eine Lagerung erfordert, die einem erheblichen Verschleiss unterliegt.The connecting rod is a critical solution as a construction element because it is connected to the leaf support requires storage that is subject to considerable wear.

Innerhalb kurzer Zeitintervalle anstehende Wartungsarbeiten wären die Folge, was die Produktivität einer solchen Webmaschine erheblich beeinträchtigen würde.Maintenance work that is due within short time intervals would be the consequence of what The productivity of such a weaving machine would be significantly affected

Ein unbeachtetes Lagerspiel überträgt sich andererseits auf die Anschlagbewegung des Webblattes in dem Sinne, dass die Qualität der Blattanschläge unterschiedlich ist. Diese Unterschiede sind im hergestellten Gewebe deutlich erkennbar und zwar als ungenügend dichte oder extrem dichte Stellen (Streifen).An unnoticed bearing play, on the other hand, is transferred to the stroke movement of the Reed in the sense that the quality of the leaf strokes is different. This Differences are clearly recognizable in the fabric that is manufactured, and that is inadequate dense or extremely dense areas (stripes).

Ein weiterer Nachteil dieser Konstruktion wird darin gesehen, dass der Antrieb nur außerhalb der Webschaftanordnung in der Webmaschine positioniert werden kann. Another disadvantage of this design is seen in the fact that the drive is only outside the heald frame arrangement can be positioned in the loom.

Dies aber erfordert eine relativ steife Konstruktion, um eine oszillierende Bewegung der Blattstütze zu realisieren.However, this requires a relatively rigid construction in order to allow an oscillating movement of the Realize leaf support.

Der Fachmann erkennt ferner, dass die vorbekannte Antriebslösung für die Blattstütze die Leistungsfähigkeit der Webmaschine im Hinblick auf Drehzahl und auf Webbreite erheblich begrenzt.The person skilled in the art also recognizes that the known drive solution for the sheet support Performance of the weaving machine in terms of speed and weaving width considerably limited.

Vor dem Hintergrund des bekannten Standes der Technik ist es Aufgabe der Erfindung, einen Antrieb für die das Webblatt tragende Blattstütze zu schaffen, der die negativen Faktoren des Standes der Technik vermeidet.Against the background of the known prior art, it is an object of the invention to provide a To create drive for the reed support that supports the negative factors of the Avoid prior art.

Der Blattstützenantrieb soll, insbesondere im Hinblick auf geforderte Leistungsparameter der Webmaschine, nicht einschränkend wirken, der Blattstützenantrieb soll massearm ausgebildet und keinen zusätzlichen Bauraum erfordern, der Blattstützenantrieb soll in jeder Phase des Webprozesses, also beginnend mit dem Start der Webmaschine eine gleichbleibende Dynamik der Blattstützen realisieren, der Blattstützenantrieb soll Anlaufstellen im Gewebe vermeiden und schließlich soll der Blattstützenantrieb sowohl zum Weben von Glatt- als auch zum Weben von Frottiergewebe geeignet sein.The blade support drive should, in particular with regard to the required performance parameters Weaving machine, not restrictive, the blade support drive should be low-mass and require no additional installation space, the blade support drive should be in every phase of the Weaving process, i.e. a constant starting with the start of the weaving machine Realize the dynamism of the leaf supports, the leaf support drive should be contact points in the tissue to avoid and finally the blade support drive for weaving both smooth and also suitable for weaving terry fabrics.

Erfindungsgemäß wird die Aufgabe durch die Merkmale der Patentansprüche gelöst.According to the invention the object is achieved by the features of the claims.

Danach ist gemäß Patentanspruch 1 erfindungswesentlich, dass die ansich bekannte Welle der Blattstütze einer Webmaschine Teil eines elektromotorischen Direktdrehantriebes ist, der einen Stator und wahlweise einen Innenrotor oder einen Außenrotor besitzt.Thereafter, according to claim 1, it is essential to the invention that the known shaft the leaf support of a weaving machine is part of an electromotive direct rotary drive, which has a stator and optionally an inner rotor or an outer rotor.

Die Welle ist als Stator in einem Außenrotor mit einem elektrisch aktiven Bereich und einem Montageteil aufgenommen und drehfest in der Webmaschine gelagert.The shaft is a stator in an outer rotor with an electrically active area and one Mounting part picked up and rotatably stored in the weaving machine.

Das Webblatt ist, wie ansich bekannt, über eine Blattleiste und im Normalfall über mehrere Blattstützen mit dem Montageteil des Außenrotors kranschlüssig verbunden.As is known per se, the reed is over one leaf bar and normally over several Blade supports are connected to the assembly part of the outer rotor by crane connection.

Als Direktantrieb ist in Ausgestaltung der Erfindung vorgesehen, dass dieser ein elektrischer Servomotor oder ein radial ausgelegter elektrischer Linearmotor ist.As a direct drive, it is provided in an embodiment of the invention that this is an electric one Servomotor or a radial electric linear motor is.

Mit Hilfe der erfindungsgemäßen Anordnung ist es möglich, sowohl die Grundstellung der Blattstütze mit einem Drehwinkel α1 im Rahmen des Gesamtschwenkwinkels der Blattstütze beliebig einzustellen, als auch die Größe des Oszillationswinkels α2 der Blattstütze zu variieren.With the help of the arrangement according to the invention, it is possible both the basic position of the Blade support with an angle of rotation α1 within the overall pivoting angle of the blade support as desired, as well as the size of the oscillation angle α2 of the blade support vary.

Erfindungswesentlich nach den Merkmalen der Patentansprüche ist ferner, dass die Welle der Blattstütze einer Webmaschine der Rotor (Läufer) wenigstens eines elektromotorischen Direktdrehantriebes ist, während der Stator drehfest mit dem Maschinengestell verbunden ist. Die Funktion von Rotor und Stator sind in diesem Falle vertauscht.Essential to the invention according to the features of the claims is further that the shaft of Blade support of a weaving machine the rotor (rotor) of at least one electromotive Direct drive is while the stator is rotatably connected to the machine frame. The function of the rotor and stator are reversed in this case.

Sind zwei Antriebe oder lediglich ein Antrieb vorgesehen, können diese an den Enden der Blattstützwelle positioniert sein.If two drives or only one drive are provided, these can be at the ends of the Blade support shaft to be positioned.

Bei einer Mehrfachanordnung von Antrieben, also mehr als zwei Antriebe, ist es funktionsbedingt erforderlich, dass der den Stator bildende Teil im Schwenkbereich der Blattstützen eine segmentartig ausgebildete Aussparung besitzt.With a multiple arrangement of drives, i.e. more than two drives, it is functionally required that the part forming the stator in the swivel range of the Leaf supports have a segment-like recess.

Es ist verständlich, dass relativ breite Webmaschinen im Vergleich zu schmalen Webmaschinen ein höheres Drehmoment der Blattstützwelle erfordern.It is understandable that relatively wide weaving machines compared to narrow ones Looms require a higher blade support shaft torque.

Zu diesem Zweck ist in Ausgestaltung der Erfindung vorgesehen, mehrere gleichartige Antriebe über die Länge der Blattstützwelle vorzusehen.For this purpose, several similar types are provided in an embodiment of the invention Provide drives over the length of the blade support shaft.

Erfindungswesentlich nach den Merkmalen des Patentanspruches 5 ist, dass, wie bereits erwähnt, die Antriebe für die Blattstützwelle als radial ausgelegte Linearmotoren ausgebildet sind. Dabei ist die Blattstützwelle ein feststehendes Konstruktionselement. Die mit der Blattstützwelle verbundenen Blattstützen sind schwenkbeweglich um die Längsmittenachse der Blattstützwelle in Lagern aufgenommen. Die Blattstützen sind zumindest in einem Bereich zwischen Blattleiste und ihrer Lagerung auf der Blattstützwelle derartig segmentartig ausgebildet, dass ein- oder doppelseitig auf den segmentartigen Flächen mehrere Permanentmagnete angeordnet sind, die erfindungsgemäß zusammen mit der Blattstütze den Sekundärteil (Schlitten) eines elektromagnetischen Linearmotors bilden.Essential to the invention according to the features of claim 5 is that, as already mentioned, the drives for the blade support shaft designed as a radial linear motors are. The blade support shaft is a fixed construction element. The one with the Blade supports connected to blade supports are pivotable about the longitudinal center axis the blade support shaft in bearings. The leaf supports are at least in one Area between the sheet bar and its storage on the blade support shaft in such a segment-like manner formed that several on one or double sides on the segment-like surfaces Permanent magnets are arranged, which according to the invention together with the blade support Form the secondary part (slide) of an electromagnetic linear motor.

Den Primärteil des Linearmotors bilden Spulen, die auf einem ebenfalls segmentartig ausgebildeten und drehfest mit der Blattstützwelle verbundenen Spulenträger angeordnet sind, und zwar der Position der Permanentmagnete des Sekundärteils entsprechend.The primary part of the linear motor is formed by coils, which are also segment-like trained and rotatably connected to the blade support shaft spool are, according to the position of the permanent magnets of the secondary part.

Die so zueinander positionierten Primär- und Sekundärteile bilden erfindungsgemäß jeweils einen Scheibenankermotor aus.According to the invention, the primary and secondary parts positioned relative to one another each form a disc armature motor.

In weiterer Ausgestaltung der Erfindung nach den Merkmalen der Patentansprüche ist erfindungsgemäß vorgesehen, dass bei Verwendung von wenigstens zwei der erfindungsgemäßen Antriebe ein Antrieb der hinschwingenden und der andere Antrieb der herschwingenden Bewegung der Blattstützen dient.In a further embodiment of the invention according to the features of the claims According to the invention provided that when using at least two of the drives according to the invention a drive of the swinging and the other drive of the swinging movement of the leaf supports.

Zur Erfassung und Meldung der Winkelpositionen der Blattstützen innerhalb eines vorbestimmten Grenzwinkelbereiches ist wenigstens einer der Antriebe mit einem Resolver ausgestattet der signalübertragend mit der elektronischen Steuereinheit der Webmaschine verbunden ist.To record and report the angular positions of the leaf supports within a predetermined limit angle range is at least one of the drives with a resolver equipped with the electronic control unit of the weaving machine connected is.

Mit den erfindungsgemäßen Antrieben lassen sich in vorteilhafter Weise die unterschiedlichsten Anschlagspositionen und Anschlagskräfte eines Webblattes in Bezug auf die Schussfadenanschlagkante des Gewebes realisieren.With the drives according to the invention, the different stop positions and stop forces of a reed in relation to realize the weft stop edge of the fabric.

Von Vorteil ist, dass bereits beim Start der Webmaschine die Dynamik des Webblattes erreicht wird, wie sie im kontinuierlich ablaufenden Webprozess erforderlich ist.The advantage is that the dynamics of the reed are already there when the weaving machine is started is achieved as it is required in the continuously running weaving process.
