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 Webblattstütze a loom after the
Features of the preamble of
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.Commonly known in weaving machines is that the drive carrying the reed Blade support from the main drive of the weaving machine via suitable gear means is derived. It turns out in weaving machines, the most recent state of the art represent the rigid coupling between the main drive respectively the Main drive shaft and the blade support more and more as a limitation for the weaving operation, because such a coupling brings disadvantages of the shape that a change of Swivel angle of the blade support or the reed without expensive measures not possible.
Eine solche kostenaufwendige Maßnahme zur Änderung des Schwenkwinkels eines
Webblattes geht z.B. aus der EP 0 892 100 A1 hervor.
Die EP 0 892 100 A1 offenbart eine Vorrichtung zur Änderung der Anschlagstellung eines
Webblattes in einer Webmaschine.
Der Antrieb der Blattstütze (Weblade) ist vom Hauptantrieb der Webmaschine abgeleitet.
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.
Der Antrieb zur Ausführung der Grundbewegung der Blattstütze erfolgt in bekannter Weise
über eine Wirkverbindung mit dem Hauptantrieb der Webmaschine.Such a costly measure for changing the pivoting angle of a reed is evident, for example, from EP 0 892 100 A1.
EP 0 892 100 A1 discloses a device for changing the stop position of a reed in a weaving machine.
The drive of the blade support (sley) is derived from the main drive of the loom.
The blade support is known to be pivotable about a pivot axis for performing an oscillating reciprocating motion, wherein a drive member is operatively connected via gearing means to a pivot axis provided in the blade support. The reed should thus in addition to the basic movement in a position to be able to change its stop position, for example in the production of terry toweling.
The drive for carrying out the basic movement of the blade support in a known manner via an operative connection with the main drive of the loom.
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.
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.
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.
Derartige Antriebsysteme erfordern einen entsprechenden Bauraum innerhalb der
Webmaschine.
Die Antriebsysteme sind außerdem verschleissanfällig und wartungsaufwendig.EP 0 440 579 B1 discloses a drive system for a reed bearing leaf reed, which drive system is effective independently of the main drive of the weaving machine.
The drive system is comprised of means for transmitting a variable speed of an electric motor to the shaft of the reed bearing blade, the motor being controlled by a speed varying controller.
The transmission of the drive power of the electric motor to the blade support shaft thus requires a drive system, for example in the form of at least one coupling gear or an eccentric gear or a belt drive.
Such drive systems require a corresponding space within the loom.
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.
Zu diesem Zwecke greift an der das Webblatt tragenden Blattstütze ein Pleuel an.
Das Pleuel und ein Elektromagnet bilden dabei den elektromagnetischen Linearantrieb für die
Blattstütze bzw. das Webblatt aus.
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.
Neben den unbestreitbaren Vorteilen besitzt der Gegenstand gemäß der DE 198 21 094 A1
nicht unwesentliche Nachteile.
Das Pleuel stellt als Kontruktionselement eine kritische Lösung dar, weil seine Anbindung an
die Blattstütze eine Lagerung erfordert, die einem erheblichen Verschleiss unterliegt.
Innerhalb kurzer Zeitintervalle anstehende Wartungsarbeiten wären die Folge, was die
Produktivität einer solchen Webmaschine erheblich beeinträchtigen würde.
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).Furthermore, from DE 198 21 094 A1 a weaving machine is known, the reed is to be offset by means of an electromagnetic linear actuator in a controlled, reciprocating motion.
For this purpose, the reed bearing the reed supports a connecting rod.
The connecting rod and an electromagnet form the electromagnetic linear drive for the blade support or the reed.
Such a drive allows both adjust the pivot angle of the blade support arbitrarily, regardless of the main drive of the loom, as well as the sheet stop frequency to meet the needs in a simple manner.
In addition to the undeniable advantages, the article according to DE 198 21 094 A1 has not insignificant disadvantages.
The connecting rod represents as a Kontruktionselement a critical solution because its connection to the blade support requires storage, which is subject to considerable wear.
Within a short time intervals pending maintenance would be the result, which would significantly affect the productivity of such a loom.
An unnoticed bearing clearance, on the other hand, translates to the stop movement of the reed in the sense that the quality of the sheet stops is different. These differences are clearly visible in the fabric produced, namely as insufficiently 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 only outside the heald assembly can be positioned in the weaving machine.
Dies aber erfordert eine relativ steife Konstruktion, um eine oszillierende Bewegung der
Blattstütze zu realisieren.
Der Fachmann erkennt ferner, dass die vorbekannte Antriebslösung für die Blattstütze die
Leistungsfähigkeit der Webmaschine im Hinblick auf Drehzahl und auf Webbreite erheblich
begrenzt.But this requires a relatively rigid construction to realize an oscillating movement of the blade support.
The skilled person further recognizes that the previously known drive solution for the blade support significantly limits the efficiency of the weaving machine in terms of speed and weaving width.
Aus JP 59-199 841 ist ein in seiner Antriebsrichtung umkehrbarer Linear-Drehantrieb für die
Blattstütze des Webblattes einer Webmaschine bekannt. Die Blattstütze ist zusammen mit dem
Webblatt zum Zwecke des Anschlagens von wenigstens einem Schussfaden an die
Anschlagkante eines herzustellenden Gewebes um die Mittenachse einer Blattstützwelle
schwenkbeweglich gelagert und mit dem Linear-Drehantrieb durch geeignete Mittel
antriebsverbunden. Die Blattstützwelle ist hier Teil des elektro-magnetischen Linear-Direktantriebes.
Der Webblatt- bzw. Blattstützenantrieb erfordert aufgrund seiner Konzeption einen
erheblichen Bauraum zum Erzeugen der Antriebsdrehmomente und zu deren Übertragung auf
die Blattstütze.From JP 59-199 841 a reversible in its drive direction linear rotary drive for the blade support of the reed of a loom is known. The blade support is pivotally mounted together with the reed for the purpose of abutment of at least one weft thread to the stop edge of a fabric to be produced about the center axis of a blade support shaft and drivingly connected to the linear rotary drive by suitable means. The blade support shaft is part of the electro-magnetic linear direct drive.
The reed or leaf propeller drive requires due to its design a considerable amount of space for generating the drive torques and their transfer to the blade support.
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.
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.Against the background of the known state of the art, the object of the invention is to provide a drive for the reed bearing leaf support, which avoids the negative factors of the prior art.
The blade propulsion drive should, in particular with regard to required performance parameters of the weaving machine, not restrictive act, the blade propulsion system massearm trained and require no additional space, the leaf propulsion drive should realize a constant dynamics of the leaf supports in each phase of the weaving process, ie starting with the start of the loom , the leaf prop drive should avoid points of contact in the tissue and finally the leaf propeller drive should be suitable both for weaving smoothing and for weaving terry cloth.
Erfindungsgemäß wird die Aufgabe durch die Merkmale der Patentansprüche 1 und 5 gelöst.According to the invention the object is solved by the features of
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.
Die Welle ist als Stator in einem Außenrotor mit einem elektrisch aktiven Bereich und einem
Montageteil aufgenommen und drehfest in der Webmaschine gelagert.
Das Webblatt ist, wie ansich bekannt, über eine Blattleiste und im Normalfall über mehrere
Blattstützen mit dem Montageteil des Außenrotors kraftschlüssig verbunden.Thereafter, according to
The shaft is received as a stator in an outer rotor with an electrically active region and a mounting part and rotatably mounted in the loom.
The reed is, as known per se, via a blade strip and normally connected via a plurality of leaf supports with the mounting part of the outer rotor non-positively.
Als Direktantrieb ist in Ausgestaltung der Erfindung vorgesehen, dass dieser ein elektrischer Servomotor oder ein radial ausgelegter elektrischer Linearmotor ist.As a direct drive is provided in an embodiment of the invention that this is an electrical Servomotor or a radially designed 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 to both the basic position of Blade support with a rotation angle α1 in the context of the total pivot angle of the blade support set 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, im Vergleich zur vorgenannten Ausbildung, vertauscht.Essential to the invention according to the features of the claims is further that the shaft of the Blade support of a loom, the rotor (rotor) at least one electromotive Direct rotary drive is, while the stator is rotatably connected to the machine frame. The function of rotor and stator are in this case, compared to the above Training, reversed.
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 Be positioned blade support shaft.
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.In a multiple arrangement of drives, so more than two drives, it is functionally required that the stator forming part in the swivel range of Leaf supports has a segment-like recess.
Es ist verständlich, dass relativ breite Webmaschinen im Vergleich zu schmalen
Webmaschinen ein höheres Drehmoment der Blattstützwelle erfordern.
Zu diesem Zweck ist in Ausgestaltung der Erfindung vorgesehen, mehrere gleichartige
Antriebe über die Länge der Blattstützwelle vorzusehen.It will be understood that relatively wide looms require higher blade support shaft torque compared to narrow looms.
For this purpose, it is provided in an embodiment of the invention to provide a plurality of similar 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 kann die Blattstützwelle ein feststehendes oder drehbewegliches
Konstruktionselement sein. Die mit der Blattstützwelle verbundenen Blattstützen sind im Falle
der feststehenden Blattstützwelle 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.
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.

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 The invention provides that when using at least two of drives according to the invention a drive of the swinging and the other drive the swinging movement of the leaf supports is used.
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.For recording and reporting the angular positions of the leaf supports within a predetermined Grenzwinkelbereiches is at least one of the drives with a resolver equipped the signal transmitting with the electronic control unit of a weaving machine connected is.

Die Figur 2 zeigt einen elektromotorischen Direktdrehantrieb 1, bei dem die Funktion von
Stator und Rotor vertauscht ist. Die Blattstützwelle 4 ist hier als Innenrotor ausgebildet. Um
den Außenumfang der Blattstützewelle 4 ist eine Vielzahl von Magneten 6 angeordnet, die mit
Spulen 5 des von einer maschinenfesten Halterung 15 getragenen Stators zusammenwirken.
Auf das Wirkprinzip beider in den Figuren 1 und 2 dargestellten elektromotorischen
Direktdrehantriebe 1 braucht an dieser Stelle nicht eingegangen zu werden, da dies dem
Fachmann hinreichend bekannt ist. FIG. 2 shows an electromotive direct
On the operating principle of both electromotive direct rotary drives 1 shown in Figures 1 and 2 need not be discussed at this point, since this is well known to the skilled person.
Figur 3 zeigt den Direktdrehantrieb 1 gem. Figur 2 in der Draufsicht. Zur Ausführung der
oszillierenden Schwenkbewegung von Blattstützwelle 4 mit Blattstütze 2 und Webblatt 3 muss
der als Spulenträger 8 ausgebildete Stator wenigstens eine dem Oszillationswinkel α2 gerecht
werdende Aussparung 16 aufweisen.FIG. 3 shows the
Gemäß Figur 4 sind erfindungsgemäß mehrere vorzugsweise gleichartige Direktdrehantriebe 1
oder Linear-Direktantriebe 10 über die Webbreite einer Webmaschine 17 vorgesehen. Dies ist
insbesondere bei Webmaschinen mit großer Webbreite sinnvoll, um hier dem wachsenden
Drehmomentenbedarf für das Schussfadenanschlagen zu genügen. Dabei sei angemerkt, dass
im Falle der Verwendung von Direktdrehantrieben 1 nicht zwingend ist, diese mit den
Blattstützen 2 in Kombination zu sehen. Denkbar ist vielmehr, dass derartige
Direktdrehantriebe 1 an anderen geeigneten Stellen auf der Blattstützewelle 4 positioniert sein
können.
Figur 4 zeigt ferner, dass wenigstens ein Direktdrehtantrieb 1 oder ein Linear-Direktantrieb 10
einen Resolver 18 besitzt, der zur Meldung der Drehwinkelstellung des Innen- oder
Außenrotors signalübertragend über die Leitungen 20 mit der Webmaschinensteuerung 19
verbunden ist.According to FIG. 4, a plurality of preferably similar direct rotary drives 1 or linear

Figur 5 zeigt den vorstehend erwähnten Linear-Direktantrieb 10 der Blattstützwelle 4.
Anstelle von elektrisch betriebenen Servormotoren können erfindungsgemäß radial ausgelegte
Linear-Direktantriebe 10 treten.
Die Blattstützwelle 4 ist im vorliegenden Falle ein feststehendes Konstruktionselement. Die
ansich starr mit der Blattstützwelle 4 verbundenen Blattstützen 2 sind erfindungsgemäß
schwenkbeweglich mittels eines Lagers 21 um die Mittenachse 4A der Blattstützwelle 4
angeordnet.
Die Blattstütze 2 selbst hat in der Seitenansicht eine geometrische Form, die es ermöglicht,
mehrere Permanentmagnete 22 - ein- oder doppelseitig - anzuordnen, die zusammen mit der
Blattstütze 2 den Sekundärteil des Linear-Direktantriebes 10 bilden. Den Primärteil des
Linear-Direktantriebes 10 bilden Spulen 23, die auf einem mit der starren Blattstützwelle 4
drehfest über Verbindungsmittel 24 verbundenen Bauteil 25 angeordnet sind.
Durch geeignete Maßnahmen lassen sich die Permanentmagnete 22 relativ zu den Spulen 23
und umgekehrt justieren.FIG. 5 shows the above-mentioned linear

doppelsseitig mit Permanentmagneten 22 ausgerüstet ist und schwenkbeweglich um die
Mittenachse 4A der maschinenfesten Blattstützwelle 4 angeordnet ist.
Zur rechten und linken Seite der Blattstütze 2 sind die die Spulen 23 tragenden Bauteile 25
drehfest mittels der Verbindungselemente 24 mit der Blattstützwelle 4 verbunden.
Auf die Wirkungsweise des Linear-Direktantriebes 10 braucht an dieser Stelle nicht näher
eingegangen zu werden, weil diese dem Fachmann bekannt ist.
Es sei jedoch darauf hingewiesen, dass im Rahmen der Erfindung auch die Umkehrung
hinsichtlich Anordnung und Funktion des in der Figur 8 dargestellten Ausführungsbeispieles
zu sehen ist.
