Description

Fadentransportvorrichtung für eine Textilmaschine, insbeson¬ dere für eine BandwebmaschineThread transport device for a textile machine, in particular for a ribbon loom
Die Neuerung betrifft eine Fadentransportvorrichtung der nn Oberbegriff des Anspruches 1 genannten Art.The innovation relates to a thread transport device of the type mentioned in the preamble of claim 1.
Fadentransportvorrichtungen sind in den verschiedensten Ausgestaltungen bekannt. In der DE-PS 946 177 ist eine Faden¬ transportvorrichtung der eingangs genannten Art beschrieben und zwar im Zusammenhang mit der Zuführung eines Gummifadens zu einer Rundstrickmaschine. Bei dieser bekannten Fadentrans¬ portvorrichtung liegt die dem Fadentransport dienende Trans¬ portwalze auf einer Reibscheibe auf und ist an einem Arm gelagert, dessen der Transportwalze abgewandtes Ende an einer Führungsachse verschwenkbar befestigt ist. Die Führungsachse ist so ausgerichtet, dass durch die Längsverschiebung der Abstand der Transportwalze vom Zentrum der Reibscheibe verän¬ dert werden kann, womit auch die Umfangsgeschwindigkeit der Transportwalze geändert wird. Auf der der Reibscheibe abge¬ wandten Seite der Transportwalze liegt eine Anpresswalze an, die ebenfalls an einem Hebel gelagert ist, der mit seinem der Anpresswalze abgewandten Ende gelenkig mit dem Hebel der Transportwalze verbunden ist. Durch Belastungsgewichte können einerseits die Anpresskraft der Transportwalze an der Reib¬ scheibe und andererseits die Anpresskraft der Anpresswalze an der Transportwalze verändert beziehungsweise, eingestellt werden. Für diese bekannten Fadentransportvorrichtung ist es nachteilig, dass sie einen relativ komplizierten Aufbau aufweist und wegen der Verwendung der Reibscheibe einen relativ grossen Platzbedarf hat, da von einer Reibscheibe nur ein Radialstrahl genutzt werden kann, jedoch der Raum für den Rest der Reibscheibe zu Verfügung gestellt werden muss. Nachteilig ist weiter, dass die Genauigkeit des Fadentrans- portes durch eine Reihe von Einflüssen negativ beeinflusst wird, so beispielsweise tritt durch die Veränderung der Betriebstemperatur zwischen dem kalten und dem warmen Zustand der Maschine eine Reibwertänderung ein. Auch Änderungen hinsichtlich Feuchtigkeit, Temperatur und Luftverschmutzung führen zu Reibwertänderungen und damit zu Schwankungen des Antriebes. Auch der Rundlauf der Reibscheibe beziehungsweise der Transportwalze sowie schwankender Anpressdruck können die Transportgenauigkeit des Fadens ebenfalls nachteilig beein¬ flussen. Weiter kommt erschwerend hinzu, dass der zu trans¬ portierende Faden einfach zwischen der Anpresswalze und der Transportwalze liegt und nicht um die Transportwalze ge¬ schlungen werden kann, da sonst ihre Auflage auf der Reib¬ scheibe beeinträchtigt würde. Durch den nur relativ kurzen Angriffsweg des Fadens an der Transportwalze beziehungsweise an der Anpressrolle ergibt sich weiter der Nachteil, dass es zu einem Durchrutschen des Fadens an der Transportwalze kommen kann, womit die Zulieferung des Fadens ebenfalls Ungenauigkeiten unterworfen ist.Thread transport devices are known in a wide variety of configurations. DE-PS 946 177 describes a thread transport device of the type mentioned at the outset, specifically in connection with the feeding of a rubber thread to a circular knitting machine. In this known thread transport device, the transport roller serving for thread transport rests on a friction disk and is supported on an arm, the end of which is remote from the transport roller and is pivotably attached to a guide axis. The guide axis is aligned so that the distance of the transport roller from the center of the friction disk can be changed by the longitudinal displacement, which also changes the peripheral speed of the transport roller. On the side of the transport roller facing away from the friction disk, there is a pressure roller, which is also mounted on a lever which is connected in an articulated manner to the lever of the transport roller with its end facing away from the pressure roller. By means of loading weights, the contact pressure of the transport roller on the friction disk and, on the other hand, the contact force of the contact roller on the transport roller can be changed or adjusted. It is disadvantageous for this known thread transport device that it has a relatively complicated structure and, because of the use of the friction disk, requires a relatively large amount of space, since only one radial jet can be used by a friction disk, but the space is made available for the rest of the friction disk got to. Another disadvantage is that the accuracy of the thread transfer portes is negatively influenced by a number of influences, for example, the change in the operating temperature between the cold and the warm state of the machine causes a change in the coefficient of friction. Changes in moisture, temperature and air pollution also lead to changes in the coefficient of friction and thus to fluctuations in the drive. The concentricity of the friction disk or the transport roller as well as fluctuating contact pressure can also adversely affect the transport accuracy of the thread. Another complicating factor is that the thread to be transported simply lies between the pressure roller and the transport roller and cannot be wrapped around the transport roller, since otherwise its bearing on the friction disk would be impaired. Due to the relatively short path of attack of the thread on the transport roller or on the pressure roller, there is the further disadvantage that the thread can slip through on the transport roller, which means that the supply of the thread is also subject to inaccuracies.
Aufgabe der Neuerung ist es, eine Fadentransportvorrichtung der eingangs genannten Art weiter zu verbessern, so dass die Nachteile des Standes der Technik überwunden werden.The object of the innovation is to further improve a thread transport device of the type mentioned at the outset, so that the disadvantages of the prior art are overcome.
Die Aufgabe wird gelöst durch die kennzeichnenden Merkmale des Anspruches 1.The object is achieved by the characterizing features of claim 1.
Dadurch, dass bei sonst konstanter Drehzahl die Transportge¬ schwindigkeit lediglich durch Expandieren des Mantels der Transportwalze bei sonst konstanter Drehzahl geändert werden kann, ergibt sich ein besonders einfacher Aufbau der Faden¬ transportvorrichtung, da die Transportgeschwindigkeit auf einfachste Weise durch Änderung des Durchmessers der Trans¬ portwalze angepasst werden kann. Bei zunehmendem Durchmesser der Transportwalze ergibt sich bei konstanter Drehzahl eine Erhöhung der Transportgeschwindigkeit. Umgekehrt führt eine Reduzierung des Durchmessers der Transportwalze zu einer Verminderung der Fördergeschwindigkeit. Die Fadentransport¬ vorrichtung kann ausserordentlich kompakt gebaut werden, benötigt also nur sehr wenig Einbauraum in einer Maschine. Ausserdem ist der Aufbau der Vorrichtung sehr einfach und damit kostengünstig.The fact that the transport speed can be changed at an otherwise constant speed merely by expanding the jacket of the transport roller at an otherwise constant speed results in a particularly simple construction of the thread transport device, since the transport speed is very simple by changing the diameter of the transport port roller can be adjusted. With an increasing diameter of the transport roller, a constant speed results in a Increase in transportation speed. Conversely, a reduction in the diameter of the transport roller leads to a reduction in the conveying speed. The thread transport device can be built to be extremely compact, so it requires very little installation space in a machine. In addition, the structure of the device is very simple and therefore inexpensive.
Vorteilhafte Ausgestaltungen der Fadentransportvorrichtung sind in den Ansprüchen 2 bis 13 beschrieben.Advantageous embodiments of the thread transport device are described in claims 2 to 13.
Der Mantel kann aus den verschiedensten Materialien, z.B. aus einem aufgerauhten, sich in Umfangsrichtung überlappenden Stahlbandstreifen bestehen, der durch eine expandierbare Stützvorrichtung gehalten ist. Vorteilhafter ist eine Ausge¬ staltung nach Anspruch 2, die besonders preiswert ist und gleichzeitig auch eine Manteloberfläche mit erhöhtem Reibwert liefert.The jacket can be made from a wide variety of materials, e.g. consist of a roughened, overlapping circumferential steel strip which is held by an expandable support device. A configuration according to claim 2, which is particularly inexpensive and at the same time also provides a jacket surface with an increased coefficient of friction, is more advantageous.
Für die Ausgestaltung der Stellvorrichtung ergeben sich ebenfalls die verschiedensten Möglichkeiten, wobei Anspruch 3 eine sehr einfache platzsparende Lösung beschreibt. Der Stellvorgang kann in einfachster Weise in der Ausgestaltung nach Anspruch 4 vorsieh gehen, wobei jedoch dann eine Ein¬ stellung nur bei stillstehender Fadentransportvorrichtung möglich ist.There are also a wide variety of options for the design of the adjusting device, claim 3 describing a very simple, space-saving solution. The actuating process can be carried out in the simplest manner in the embodiment according to claim 4, but adjustment is then only possible when the thread transport device is at a standstill.
Eine weitere Variante der Einsteilvorrichtung beschreibt Anspruch 5. Die zur Einstellung notwendige Einstellvorrich¬ tung kann gemäss Anspruch 6 ausgestaltet sein. Auch hier ist eine Einstellung nur bei stillstehender Transportvorrichtung möglich.Claim 5 describes a further variant of the adjusting device. The adjustment device required for adjustment can be designed according to Claim 6. Here too, adjustment is only possible when the transport device is at a standstill.
Soll der Durchmesser der Faden-Transportwalze auch während des Betriebes veränderbar sein, so ist eine Ausgestaltung nach Anspruch 8 von Vorteil. Die ortsfeste Einsteilvorrich¬ tung kann auf die verschiedenste Weise ausgebildet sein, angefangen von einer einfachen Stellschraube, über einen motorischen Spindeltrieb bis zu fluidbetätigten Kolbenzylin¬ deraggregaten.If the diameter of the thread transport roller should also be changeable during operation, this is an embodiment according to claim 8 is advantageous. The stationary Einteilvorrich¬ device can be designed in a variety of ways, starting from a simple set screw, a motorized spindle drive to fluid-operated piston-cylinder units.
Der Anspruch 9 beschreibt eine besonders einfache Ausbildung und Lagerung der Anpresswalze.The claim 9 describes a particularly simple design and storage of the pressure roller.
Für die Anordnung des zu transportierenden Fadens an der Transportwalze und an der Anpresswalze ergeben sich die verschiedensten Möglichkeiten. Im einfachsten Fall kann der Kontakt zwischen dem zu transportierenden Faden und der Transportwalze und der Antriebswalze lediglich durch Hin¬ durchführen des Fadens an der Berührungsstelle zwischen der Transportwalze und der Anpresswalze erfolgen. Die Genaugkeit und Sicherheit des Fadentransportes lässt sich durch die Ausgestaltung nach Anspruch 10 verbessern, da durch die teilweise Umschlingung des Fadens um die Anpresswalze die aufbringbare Reibkraft wesentlich erhöht ist.There are various possibilities for arranging the thread to be transported on the transport roller and on the pressure roller. In the simplest case, the contact between the thread to be transported and the transport roller and the drive roller can only take place by passing the thread at the point of contact between the transport roller and the pressure roller. The accuracy and safety of the thread transport can be improved by the embodiment according to claim 10, since the friction force that can be applied is increased significantly by the partial wrap of the thread around the pressure roller.
Schwankungen im Fadentransport und/oder im Fadenverbrauch lassen sich durch eine Ausgestaltung der Fadentransportvor¬ richtung nach Anspruch 11 ausgleichen.Fluctuations in the thread transport and / or in the thread consumption can be compensated for by designing the thread transport device according to claim 11.
Gegebenenfalls kann es zweckmässig sein, die durch Verände¬ rung des Durchmessers der Faden-Transportwalze bedingte Änderung der Transportgeschwindigkeit nur für Einstell- und Ausgleichszwecke zu verwenden und grössere Antriebsanpassun¬ gen durch eine Ausgestaltung der Fadentransportvorrichtung nach Anspruch 12 vorzunehmen. Die erwähnten Vorteile kommen insbesondere bei einer Ausgestaltung der Fadentransportvor¬ richtung nach Anspruch 13 zum Tragen, wo auf einer antreibba¬ ren Welle zwei und mehrere Faden-Transportwalzen nebeneinan¬ der angeordnet sind, deren Transporteigenschaften einerseits aufeinander und andererseits auf den Fadenverbrauch einge¬ stellt werden müssen.If appropriate, it may be expedient to use the change in the transport speed due to the change in the diameter of the thread transport roller only for setting and compensating purposes and to make larger drive adjustments by designing the thread transport device according to claim 12. The advantages mentioned are particularly evident in an embodiment of the thread transport device according to claim 13, where two and more thread transport rollers are arranged side by side on a drivable shaft, the transport properties of which are on the one hand on each other and on the other hand must be adjusted to the thread consumption.

Dieser Stellblock ist zwischen zwei Pressgliedern 68,70 eingespannt, von denen das erste Pressglied 68 auf der Welle 8 fest an¬ geordnet ist und das zweite Pressglied 70 aus einer auf der Welle verschiebbaren Scheibe 70 besteht, die mittels einer Einstellmutter 72 gegen das erste Pressglied 68 verspannbar ist. Hierzu ist die Einstellmutter 72 auf einem Gewindeab¬ schnitt 74 der Welle angeordnet. Durch Zusammenpressen der Pressglieder 68,70 wird der Stellblock 66 in radialer Rich¬ tung expandiert und wirkt über eine Stützvorrichtung 76, beispielsweise in Form von Walzenkörpern oder einer ge¬ schlitzten Hülse mit sich in Umfangsrichtung überlappenden Endabschnitten, auf einen Mantel 78, der die Reiboberfläche 32 bildet. Der Mantel 78 besteht vorzugsweise ebenfalls aus elastomerem Material. Durch Komprimieren des Stellblockes 76 mittels der Pressglieder 68,70 wird der Mantel 78 radial nach aussen gedrückt, so dass sich der Durchmesser D vergrossert. Beim Entspannen des Stellblockes 66 mittels der Pressglieder 68,70 zieht sich der Mantel 78 zusammen, was zur Reduktion des Durchmesser D führt. An dem Mantel 78 liegt auf der Reiboberfläche 32 der Faden 26 auf, der mittels der Anpress¬ walze 12 gegen die Transportwalze 10 gedrückt wird. In Figur 2 ist auch schematisch angedeutet, wie die Anpresswalze 12 auf der Welle 16 angeordnet und am Hebel 14 gehalten ist, der mittels der Feder 22 gegen die Transportwalze 10 vorgespannt ist.FIG. 2 shows a first embodiment of a transport roller 10 and a pressure roller 12. The transport roller 10 has an adjusting block 66 on the shaft 8, which is formed from a quasi incompressible, elastomeric material. This The adjusting block is clamped between two pressing members 68, 70, of which the first pressing member 68 is fixedly arranged on the shaft 8 and the second pressing member 70 consists of a disk 70 which can be displaced on the shaft and which is set against the first pressing member 68 by means of an adjusting nut 72 is tense. For this purpose, the adjusting nut 72 is arranged on a threaded section 74 of the shaft. By pressing the pressing members 68, 70 together, the adjusting block 66 is expanded in the radial direction and acts on a jacket 78, which has the friction surface, via a support device 76, for example in the form of roller bodies or a slotted sleeve with end sections overlapping in the circumferential direction 32 forms. The jacket 78 is preferably also made of elastomeric material. By compressing the adjusting block 76 by means of the pressing members 68, 70, the jacket 78 is pressed radially outward, so that the diameter D increases. When the adjusting block 66 is relaxed by means of the pressing members 68, 70, the jacket 78 contracts, which leads to a reduction in the diameter D. The thread 26 rests on the jacket 78 on the friction surface 32 and is pressed against the transport roller 10 by means of the pressure roller 12. In Figure 2 is also indicated schematically how the pressure roller 12 is arranged on the shaft 16 and held on the lever 14 which is biased by the spring 22 against the transport roller 10.
Die Figur 3 zeigt eine der Figur 2 entsprechende Anordnung der Transportwalze 10 und der Anpresswalze 12, wobei jedoch die Einstellmutter 72 ersetzt ist durch eine ortsfeste Ein- stellvorrichtung 80, die gebildet ist aus einem zweiarmigen Koppelglied 82, das an einem ortsfesten Lagerbock 84 ver¬ schwenkbar gelagert ist. An dem der Transportwalze 10 abge¬ wandten Ende 86 ist das Koppelglied 82 mit einer Antriebsmit¬ tel 88 verbunden, die beliebig ausgestaltet sein kann und zwar von einer einfachen Stellschraube, über eine Antriebs- spindel bis zu einem fluidbetätigten Zylinderaggregat. Der dem Pressglied 70 zugewandte Arm 90 ist gabelförmig ausge¬ staltet und wirkt mit dem Pressglied 70 zusammen, so dass der Stellblock 66 in Abhängigkeit von der Stellung der Antriebs¬ mittel 88 mehr oder weniger zusammengepresst werden kann.FIG. 3 shows an arrangement of the transport roller 10 and the pressure roller 12 corresponding to FIG. 2, but the adjusting nut 72 is replaced by a stationary adjusting device 80, which is formed from a two-armed coupling member 82 which is attached to a stationary bearing block 84 is pivotally mounted. At the end 86 facing away from the transport roller 10, the coupling member 82 is connected to a drive means 88, which can be configured in any manner, from a simple adjusting screw via a drive spindle up to a fluid-operated cylinder unit. The arm 90 facing the pressing member 70 is fork-shaped and cooperates with the pressing member 70, so that the adjusting block 66 can be compressed more or less depending on the position of the drive means 88.
Die Figur 4 zeigt eine weitere Anordnung einer Transportwalze 10a und einer Anpresswalze 12. Der Mantel 78a der Transport¬ walze 10a ist auf der radial innen liegenden Seite 92 konisch ausgebildet und wirkt mit einem gegenkonischen Stellglied 94 zusammen, das auf der Welle 8a fest angeordnet ist. Eine Einsteilvorrichtung 96 weist eine seitlich auf den Mantel 78a einwirkende Hülse 98 auf, die sich an einer Einstellscheibe 100 abstützt, die koaxial zur Welle 8a angeordnet ist. Die Einstellscheibe 100 enthält hierzu eine zentrale Gewindeöff¬ nung 102, die auf einen Gewindeabschnitt 104 der Welle 8a aufgeschraubt ist. Die Einsteilvorrichtung 96 bestimmt mit¬ tels der Einstellscheibe 100 die axiale Stellung des Mantels 78a auf dem konischen Stellglied 94, dementsprechend ist der Durchmesser D des Mantels 78a vergrossert oder verkleinert. Anstelle der auf der Welle 8a hin- und herschraubbaren Ein¬ stellscheibe 100 kann auch eine externe, ortsfeste Stellvor¬ richtung zur Betätigung der Scheibe vorgesehen sein, so wie dies in der Figur 3 beschrieben worden ist.FIG. 4 shows a further arrangement of a transport roller 10a and a pressure roller 12. The jacket 78a of the transport roller 10a is conical on the radially inner side 92 and interacts with a counter-conical actuator 94 which is fixedly arranged on the shaft 8a . An adjusting device 96 has a sleeve 98 which acts laterally on the jacket 78a and is supported on an adjusting disk 100 which is arranged coaxially to the shaft 8a. For this purpose, the adjusting disk 100 contains a central threaded opening 102 which is screwed onto a threaded section 104 of the shaft 8a. The adjusting device 96 uses the adjusting washer 100 to determine the axial position of the casing 78a on the conical actuator 94, and accordingly the diameter D of the casing 78a is enlarged or reduced. Instead of the adjusting disk 100 which can be screwed back and forth on the shaft 8a, an external, stationary adjusting device can also be provided for actuating the disk, as has been described in FIG. 3.
Die Figur 5 zeigt die Anordnung von zwei Fadentransportvor¬ richtungen 2a und 2b, die analog der Fadentransportvorrich¬ tung der Figuren 1 und 2 ausgebildet sind. Diese Fadentrans¬ portvorrichtungen haben eine gemeinsame Welle 8b und werden von einer gemeinsamen Antriebsvorrichtung 6 betätigt. Diese enthält einen Motor 106, der eine Antriebswelle 108 antreibt, die über ein Variogetriebe 110 mit der Welle 8b der Faden¬ transportvorrichtungen verbunden ist. Durch Veränderung der Drehzahl des Motors 106 und/oder einer Veränderung des Über¬ setzungsverhältnisses des Variogetriebes 110 kann die Dreh- zahl für alle Fadentransportvorrichtungen 2a,2b gemeinsam eingestellt werden. Die Fadentransportgeschwindigkeit kann an den einzelnen Bandwebmaschinen 4a,4b, d.h. an den einzelnen Webstellen mittels der Einstellmuttern 72 durch Anpassung des Durchmessers der Transportwalzen 10 individuell fein einge¬ stellt und angepasst werden.FIG. 5 shows the arrangement of two thread transport devices 2a and 2b, which are designed analogously to the thread transport device of FIGS. 1 and 2. These thread transport devices have a common shaft 8b and are actuated by a common drive device 6. This contains a motor 106 which drives a drive shaft 108 which is connected to the shaft 8b of the thread transport devices via a vario gear 110. By changing the speed of the motor 106 and / or changing the gear ratio of the vario gear 110, the rotational speed Number for all thread transport devices 2a, 2b can be set together. The thread transport speed can be individually fine-tuned and adjusted on the individual belt looms 4a, 4b, ie on the individual looms, by means of the adjusting nuts 72 by adjusting the diameter of the transport rollers 10.
Mittels der neuerungsgemässen Fadentransportvorrichtung ergeben sich also eine ganze Reihe entscheidender Vorteile. So ist eine absolute, positive und exakte Fadentransportmenge und deren Einstellung sichergestellt durch:Using the thread transport device according to the innovation, a whole series of decisive advantages result. An absolute, positive and exact thread transport quantity and its setting is ensured by:
a) die Umschlingung des Fadens an der Transportwalze und die Anpressung des Fadens mittels der Anpresswalze;a) wrapping the thread on the transport roller and pressing the thread by means of the pressure roller;
b) die Fadenmengen-Einstellung durch Vergrössern beziehungs¬ weise Verkleinern des Durchmessers der Transportwalze ohne Veränderung der Drehzahl der Transportwalzen und/oderb) the thread quantity setting by enlarging or reducing the diameter of the transport roller without changing the speed of the transport rollers and / or
c) individuelle Abstimmung mehrerer auf einer gemeinsamen Antriebswelle angeordneter Fadentransportvorrichtungen.c) individual coordination of several thread transport devices arranged on a common drive shaft.
Aufgrund der Umschlingung des Faden an der Reiboberfläche der Fadentransportvorrichtung einerseits und der Anpressung des Fadens mittels der Anpresswalze andererseits ergibt sich eine zwangsweise Führung und ein zwangsweiser Transport des Fa¬ dens, der auf äussere Einflüsse wie Temperatur, Klima und Verschmutzung nicht anfällig ist. Schliesslich ist die Faden¬ transportvorrichtung aufgrund des ausserordentlich einfachen Aufbaus und der Einstellung ausserordentlich raumsparend und kann deshalb auch auf kleinstem Raum zum Einsatz kommen und bedient werden. Weiter ist er wegen der nur geringen Anzahl der Bauteile nicht nur kostengünstig sondern weist überdies eine verringerte Verschleissanfälligkeit auf. Durch den exakten zwangsweisen Antrieb des Fadens mittels der Faden¬ transportvorrichtung ergibt sich praktisch auch keine Schlupf beim Starten und Stoppen der Webmaschine, so dass die sich sonst häufig einstellende Webfehler vermieden werden. Das Gleiche gilt auch für eine exakte Beibehaltung der Bandbreite aufgrund der exakten gesteuerten Zuführung des Fadens für eine Schusseintragnadel. Due to the looping of the thread on the friction surface of the thread transport device on the one hand and the pressing of the thread by means of the pressure roller on the other hand there is a forced guidance and a forced transport of the thread which is not susceptible to external influences such as temperature, climate and pollution. Finally, the thread transport device is extremely space-saving due to the extremely simple construction and the setting and can therefore be used and operated even in the smallest space. Furthermore, because of the small number of components, it is not only inexpensive but also has a reduced susceptibility to wear. By the exact forced driving of the thread by means of the thread transport device practically does not result in any slippage when starting and stopping the weaving machine, so that the weaving errors that otherwise occur frequently are avoided. The same also applies to an exact maintenance of the bandwidth due to the precisely controlled feeding of the thread for a weft insertion needle.
