Description

Die Erfindung betrifft eine kombinierte Ausbreit- und Quetschvorrichtung, insbesondere für Schlauch-Wirkware mit den Merkmalen des Oberbegriffs des Anspruchs 1.
Eine derartige Vorrichtung ist vorzugsweise dafür vorgesehen, Bugmarkierungen in naßveredelter Schlauch-Wirkware zu vermeiden, die beim Ausquetschen der Behandlungsflotte entstehen.
The invention relates to a combined spreading and squeezing device, in particular for tubular knitted fabrics with the features of the preamble of claim 1.
Such a device is preferably intended to avoid bow markings in wet-finished tubular knitted fabric which arise when the treatment liquor is squeezed out.

Bekannt ist aus der DE-OS 41 23 477 A1 eine Vorrichtung zur Vermeidung von Bugmarkierungen in Schlauch-Wirkware. Nach dieser bekannten Vorrichtung wird die Schlauch-Wirkware zwischen einem rotierbaren und im Durchmesser verstellbaren inneren Quetschwalzensystem und einem rotierbaren äußeren Quetschwalzensystem geführt.
Der strukturelle Aufbau des inneren Quetschwalzensystems entspricht dem eines Rundbreithalters gemäß der DE-PS 37 32 754. Allerdings ist an den freien Enden der Abstützungen anstelle von Längsführungselementen jeweils ein Quetschwalzenpaar angeordnet.
Jedes Quetschwalzenpaar des inneren Systems bildet zusammen mit einer Quetschwalze des äußeren Systems ein sogenanntes Teilquetschwerk.
Beim Abquetschen der Schlauchware greift zwischen die Quetschwalzen jedes Quetschwalzenpaares jeweils eine drehangetriebene Quetschwalze des äußeren Systems gesteuert ein. Die Behandlungsflotte wird auf diese Weise weitgehend aus der Schlauch-Wirkware gequetscht.
DE-OS 41 23 477 A1 discloses a device for avoiding bow markings in tubular knitted fabrics. According to this known device, the tubular knitted fabric is guided between a rotatable and diameter-adjustable inner squeeze roller system and a rotatable outer squeeze roller system.
The structural structure of the inner squeeze roller system corresponds to that of a circular spreader according to DE-PS 37 32 754. However, a pair of squeeze rollers is arranged at the free ends of the supports instead of longitudinal guide elements.
Each pair of squeeze rollers of the inner system, together with a squeeze roller of the outer system, forms a so-called partial squeeze mechanism.
When the tubular goods are squeezed, a rotationally driven squeeze roller of the outer system engages between the squeeze rollers of each pair of squeeze rollers. The treatment liquor is largely squeezed out of the tubular knitted fabric in this way.

Ist aufgrund des Durchmessers der Schlauch-Wirkware nur eine geringe Ausbreitung erforderlich bzw. zulässig, dann stehen die Abstützungen des inneren Systems in einem relativ flachen Winkel zur Längsachse des zentralen Breithalter-Trägers. Dadurch wirken relativ große Hebelkräfte aus dem Quetschvorgang auf die Abstützungen und auf deren Lagerung am zentralen Träger. Diese Kräfte erfordern dementsprechend dimensionierte Elemente des Breithalters.If, due to the diameter of the tubular knitted fabric, only a small spread is required or permitted, then the Support the inner system at a relatively flat angle to the longitudinal axis of the central spreader beam. As a result, relatively large leverage forces from the squeezing process act on the supports and on their support on the central support. These forces require correspondingly dimensioned elements of the spreader.

Aufgabe der Erfindung ist es, die schwenkbar am zentralen Träger der bekannten kombinierten Ausbreit- und Quetschvorrichtung angeordneten Abstützungen und den zentralen Träger selbst von den Quetschkräften, die von den Quetschwerken ausgehen, zu entlasten und damit auf eine massive und schwere Ausbildung der Vorrichtung zu verzichten.The object of the invention is to relieve the pivotably arranged on the central support of the known combined spreading and squeezing supports and the central support itself from the squeezing forces emanating from the squeezing devices, and thus to dispense with a massive and heavy design of the device.

Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß die Quetschwalzenpaare von den Abstützungen des zentralen Trägers getrennt sind, indem die Quetschwalzenpaare am Außenrohr des zentralen Trägers in stationären Aufnahmen drehbeweglich gelagert sind und jedem Quetschwalzenpaar die drehangetriebene Quetschwalze zusammen mit der Kolben-Zylindereinheit derart diametral gegenüberliegend am jeweiligen Lagerring des Lagerringpaares positioniert ist, daß sich die von den Kolben-Zylindereinheiten ausgehenden Quetschkräfte direkt gegenseitig abstützen.
An den freien Enden der Abstützungen sind anstelle der Quetschwalzenpaare in an sich bekannter Weise Ausbreitelemente, z.B. Ausbreitrollen angeordnet.
According to the invention the object is achieved in that the squeeze roller pairs are separated from the supports of the central carrier, in that the squeeze roller pairs are rotatably mounted on the outer tube of the central carrier in stationary receptacles and each squeeze roller pair has the rotationally driven squeeze roller together with the piston-cylinder unit so diametrically opposite each The bearing ring of the pair of bearing rings is positioned so that the squeezing forces emanating from the piston-cylinder units are supported directly against one another.
Spreading elements, for example spreading rollers, are arranged at the free ends of the supports instead of the pairs of squeezing rollers in a manner known per se.

Der zentrale Träger ist in Art eines Teleskoprohres ausgebildet. Dieser Träger besteht aus einem ersten Teleskoprohr, an dem, in Richtung seiner Längsachse gesehen, beabstandet voneinander obere und untere Walzenaufnahmen vorhanden sind.The central support is designed in the manner of a telescopic tube. This carrier consists of a first telescopic tube, on which, viewed in the direction of its longitudinal axis, there are upper and lower roller mounts spaced apart from one another.

Die oberen und unteren Walzenaufnahmen dienen den einzelnen Quetschwalzen der Quetschwalzenpaare als Drehlager.The upper and lower roller mounts serve as the rotary bearing for the individual nip rollers of the nip roller pairs.

Auf jedes der Walzenpaare ist eine drehangetriebene Quetschwalze zur Bildung eines Quetschspaltes radial zustellbar. Jedes Quetschwalzenpaar bildet zusammen mit der erwähnten Quetschwalze ein Quetschwerk.
In Bezug auf die Längsachse des zentralen Trägers sind in an sich bekannter Weise die Längsachsen der einzelnen Walzen jedes Quetschwerkes in einem Winkel schräg zur Trägerlängsachse positioniert. Damit ist gewährleistet, daß die mittels der Abstützungen und der Ausbreitelemente ausgebreitete und zwischen den einzelnen Quetschwerken geführte Schlauch-Wirkware, entsprechend der Drehrichtung der drehangetriebenen Quetschwalze, durch die Quetschwerke hindurchgeführt und die Behandlungsflotte ausgequetscht werden kann.
Mit der erfindungsgemäßen Lösung wird in vorteilhafter Weise erreicht, daß die in den einzelnen Quetschwerken wirkenden Quetschkräfte sich direkt gegenseitig abstützen. Aufgrund der Anordnung der einzelnen Quetschwalzenpaare am zentralen Träger werden die Abstützungen und deren Lager nicht mehr durch die Quetschkräfte beansprucht. Die Abstützungen haben lediglich die sich aus dem Breithalten der Schlauch-Wirkware ergebenden Kräfte aufzunehmen.
A rotationally driven nip roller can be radially advanced to each of the roller pairs to form a nip. Each pair of squeeze rollers forms a squeeze mechanism together with the squeeze roller mentioned.
With respect to the longitudinal axis of the central carrier, the longitudinal axes of the individual rollers of each squeezing mechanism are positioned at an angle obliquely to the longitudinal axis of the carrier in a manner known per se. This ensures that the tubular knitted fabric, which is spread out by means of the supports and the spreading elements and is guided between the individual squeezing units, can be passed through the squeezing units and the treatment liquor can be squeezed out, in accordance with the direction of rotation of the driven squeeze roller.
With the solution according to the invention it is advantageously achieved that the squeezing forces acting in the individual squeezing mechanisms are mutually supported directly. Due to the arrangement of the individual squeeze roller pairs on the central support, the supports and their bearings are no longer stressed by the squeeze forces. The supports only have to absorb the forces that result from holding the tubular knitted fabric wide.

Eine ähnliche konstruktive Lösung ist zwar an sich aus CH-A-460 687 bekannt, jedoch nicht im Zusammenhang mit einem gattungsgemäßen Rundbreithalter.A similar constructive solution is known per se from CH-A-460 687, but not in connection with a generic circular spreader.

Zum besseren Verständnis der erfindungsgemäßen Lösung und der Vorrichtung insgesamt ist die Ausbreit- und Quetschvorrichtung in Verbindung mit den Einrichtungen der Gesamtanlage in Fig. 1 dargestellt.For a better understanding of the solution according to the invention and the device as a whole, the spreading and squeezing device in connection with the facilities of the overall system is shown in FIG. 1.

In Fig. 1 liegt die Schlauch-Wirkware 1 strangförmig vor. Die Schlauch-Wirkware 1 ist in einem von einem Drehteller 2 getragenen Trog 3 abgelegt. Von dem Trog 3 aus läuft die Ware 1 über einen Drehspanner 4 zu einen am Gestell 5 angeordneten Entwirrkopf 6. Dem Entwirrkopf 6 ist ein am Gestell 5 befestigter Flachbreithalter 7 nachgeordnet, mit welchem die Schlauchware 1 flach breitgehalten wird. Die Schlauchware 1 gelangt nachfolgend über eine erste Umlenkwalze 8 zu einer unterhalb eines Fixierrollenpaares 9 angeordneten zweiten Umlenkwalze 10. Nach der Umlenkwalze 10 ist ein unterer Breithalterkopf 11, bestehend aus paarweise angeordneten Stützrollen 11a und den paarweise zugeordneten Fixierrollen 9 vorgesehen. Die Ware 1 läuft nun zwischen den Stützrollen 11a und den Fixierrollen 9 hindurch und wird von der Ausbreitvorrichtung mit Ausbreitrollen 12 ausgebreitet und durch einzelne Quetschwerke 13 derart geführt, daß die Flotte nach unten in den Flottenbehälter 14 an der zugeführten Schlauchware 1 ablaufen kann.In Fig. 1, the tubular knitted fabric 1 is stranded. The tubular knitted fabric 1 is stored in a trough 3 carried by a turntable 2. The goods 1 run from the trough 3 via a rotary tensioner 4 to a detangling head 6 arranged on the frame 5. The tubular fabric 1 subsequently passes via a first deflecting roller 8 to a second deflecting roller 10 arranged below a pair of fixing rollers 9. After the deflecting roller 10, a lower spreader head 11, consisting of support rollers 11a arranged in pairs and the fixing rollers 9 assigned in pairs, is provided. The product 1 now runs between the support rollers 11a and the fixing rollers 9 and is spread out by the spreading device with spreading rollers 12 and guided by individual squeezing mechanisms 13 in such a way that the liquor can run down into the liquor container 14 on the tube material 1 supplied.

Nach dem Quetschen wird die Ware 1 über einen oberen Breithalterkopf 15, bestehend aus einem Stützrollenpaar 15a und einem Fixierrollenpaar 15b, geführt und in flach ausgebreiteter Form von einer angetriebenen Walzen-Anordnung 16, die im oberen Bereich des Gestells 5 vorgesehen ist, abgezogen.
Zum Erreichen einer konstanten Warenabzugskraft kann die Ware 1 vor der Walzen-Anordnung 16 über eine nach dem oberen Breithalterkopf 15 vorgesehene, nicht dargestellte Tänzerwalze mit einstellbarer Spannkraft geführt werden.
After the squeezing, the goods 1 are guided over an upper spreader head 15, consisting of a pair of support rollers 15a and a pair of fixing rollers 15b, and are pulled off in a flatly spread form by a driven roller arrangement 16, which is provided in the upper region of the frame 5.
In order to achieve a constant pull-off force, the goods 1 can be guided in front of the roller arrangement 16 via a dancer roller, not shown, provided after the upper spreader head 15, with adjustable clamping force.

Im unteren Teil des Gestells 5 ist eine Trag- und Verstellvorrichtung 17 für die kombinierte Ausbreit- und Quetschvorrichtung vorgesehen. Die Vorrichtung 17 kann in Richtung der Doppelpfeile 18 den unteren Breithalterkopf 11 anheben oder absenken. Damit kann die den unteren Breithalterkopf 11 tragende Vorrichtung 17 den teleskopartig ausgebildeten zentralen Träger 19 (Fig. 4), an dem untere und obere Abstützungen 20,21 angelenkt sind, in der Höhe verstellen.
Der zentrale Träger 19 besteht hier aus einem Außenrohr 19a und einem in das Außenrohr 19a teleskopartig verschiebbarem Innenrohr 19b.
Das freie Ende des Außenrohres 19a ist mit dem oberen Breithalterkopf 15 und das freie Ende des Innenrohres 19b mit dem unteren Breithalterkopf 11 über ein Drehlager 22 (Fig. 4) verbunden.
Die Ausbreit- und Quetschvorrichtung ist damit zwischen den beiden Breithalterköpfen 11,15 rotierbar gehalten.
In the lower part of the frame 5, a carrying and adjusting device 17 is provided for the combined spreading and squeezing device. The device 17 can raise or lower the lower spreader head 11 in the direction of the double arrows 18. Thus, the device 17 carrying the lower spreader head 11 can adjust the height of the telescopic central support 19 (FIG. 4), to which lower and upper supports 20, 21 are articulated.
The central support 19 here consists of an outer tube 19a and an inner tube 19b which can be telescopically displaced into the outer tube 19a.
The free end of the outer tube 19a is connected to the upper spreader head 15 and the free end of the inner tube 19b to the lower spreader head 11 via a rotary bearing 22 (FIG. 4).
The spreading and squeezing device is thus held rotatably between the two spreader heads 11, 15.

An den freien Enden der Abstützungen 20,21 ist wenigstens eine Ausbreitrolle 12 vorhanden.At least one spreading roller 12 is provided on the free ends of the supports 20, 21.

Jeweils zwei Quetschwalzen 23a und 23b bilden ein Quetschwalzenpaar 23. Jedem Quetschwalzenpaar 23 ist eine Quetschwalze 26 zugeordnet, die zusammen ein Quetschwerk 13 ausbilden. Die Quetschwalzenpaare 23 sind stationär angeordnet, d.h., im Gegensatz zum Stand der Technik, nicht radial verstellbar und vorzugsweise an dem Teleskoprohr 19a des zentralen Trägers 19 in entsprechenden Walzenaufnahmen 24, 25 drehend gelagert.Two squeeze rollers 23a and 23b each form a pair of squeeze rollers 23. Each squeeze roller pair 23 is assigned a squeeze roller 26, which together form a squeeze mechanism 13. The nip roller pairs 23 are arranged in a stationary manner, i.e., in contrast to the prior art, cannot be adjusted radially and are preferably rotatably mounted on the telescopic tube 19a of the central support 19 in corresponding roller mounts 24, 25.

Vorzugsweise am Außenumfang des Außenrohres 19a ist erfindungsgemäß zwischen den Anlenkungen der bereits erwähnten Abstützungen 21 eine obere Walzenaufnahme 24 und zwischen den Anlenkungen der Abstützungen 20, 21 eine untere Walzenaufnahme 25 vorhanden. Beide Walzenaufnahmen 24,25 sind, über die Länge des Außenrohres 19a gesehen, beabstandet voneinander angeordnet und zwar derart, daß in den Walzenaufnahmen 24,25 die Quetschwalzen 23a,23b der einzelnen Quetschwalzenpaare 23 drehbar gelagert sind.
Wesentlich ist dabei, daß die betreffenden Lagerstellen der einzelnen Quetschwalzen 23a,23b in der oberen Walzenaufnahme 24 relativ zu den Lagerstellen der unteren Walzenaufnahme 25 versetzt ausgerichtet sind, d.h. nicht fluchtend gegenüberliegen. Dadurch weist jede Längsachse der Quetschwalzen 23a, 23b in Bezug auf die Längsachse des zentralen Trägers 19 eine Schrägstellung von einigen Winkelgraden auf.
Die gleiche Schrägstellung besitzt auch jede der auf das jeweilige Quetschwalzenpaar 23 radial verstellbaren und drehangetriebenen Quetschwalze 26.
According to the invention, preferably on the outer circumference of the outer tube 19a, there is an upper roller seat 24 between the articulations of the supports 21 already mentioned and a lower roller seat 25 between the articulations of the supports 20, 21. Both roller receptacles are 24.25 over the length of the Seen outer tube 19a, spaced from each other and in such a way that the nip rollers 23a, 23b of the individual nip roller pairs 23 are rotatably mounted in the roller receptacles 24,25.
It is important that the relevant bearing points of the individual squeeze rolls 23a, 23b in the upper roll holder 24 are offset relative to the bearing points of the lower roll holder 25, ie they are not aligned opposite one another. As a result, each longitudinal axis of the squeeze rollers 23a, 23b has an oblique position of a few angular degrees with respect to the longitudinal axis of the central carrier 19.
Each of the squeeze rollers 26, which is radially adjustable and driven in rotation on the respective pair of squeeze rollers 23, also has the same inclined position.

Die Figuren 2 bis 4 zeigen die erfindungsgemäße Anordnung der einzelnen Quetschwalzenpaare 23 mit der zugehörigen drehangetriebenen Quetschwalze 26.
Die auszuquetschende Schlauch-Wirkware 1 ist, wie in Fig. 2 gezeigt, zum einen über die Ausbreitrollen 12 und zum anderen durch einen einstellbaren Quetschspalt in jedem Quetschwerk 13 geführt.
Der Quetschspalt und damit auch die auf die Schlauch-Wirkware 1 wirkende Quetschkraft "F" ist mittels der die jeweilige Quetschwalze 26 tragenden Kolben-Zylindereinheit 27 einstellbar.
FIGS. 2 to 4 show the arrangement according to the invention of the individual pinch roller pairs 23 with the associated rotationally driven pinch roller 26.
The tubular knitted fabric 1 to be squeezed out, as shown in FIG. 2, is guided on the one hand over the spreading rollers 12 and on the other hand through an adjustable squeeze gap in each squeeze mechanism 13.
The squeezing gap and thus also the squeezing force "F" acting on the tubular knitted fabric 1 can be adjusted by means of the piston-cylinder unit 27 carrying the respective squeezing roller 26.

Die einzelnen Quetschwalzen 26 sind an ihren freien Enden mit der Kolbenstange 27a der Kolben-Zylindereinheit 27 verbunden. Die Kolben-Zylindereinheiten 27 fungieren dabei als Tragorgan für die Quetschwalzen 26 und gleichzeitig zur Erzeugung der erforderlichen Quetschkraft "F".
Die an den oberen und unteren Ende der Quetschwalze (26) angreifenden Kolben-Zylindereinheiten 27 sind in bekannter Weise mit einem drehangetriebenen Lagerring-Paar 28 verbunden.
The individual squeeze rollers 26 are connected at their free ends to the piston rod 27a of the piston-cylinder unit 27. The piston-cylinder units 27 act as a support member for the squeeze rollers 26 and at the same time to generate the required squeeze force "F".
The piston-cylinder units 27 acting on the upper and lower ends of the squeeze roller (26) are connected in a known manner to a pair of rotationally driven bearing rings 28.

Das Lagerring-Paar 28 ist in dem Gestell 5 aufgenommen, wie dies ausschnittsweise in Fig. 4 dargestellt ist.
Mit dem Längsträger 5a des Gestells 5 sind Querträger 5b verbunden.
Die Querträger 5b nehmen Lagerrollen 30 auf, die die drehangetriebenen Lagerringe 28,29 unterstützen.
Auf den Antrieb der einzelnen Lagerringe 28,29 soll hier nicht weiter eingegangen werden, da dieser bereits in der vorbekannten DE-OS 41 23 477 A1 ausführlich beschrieben wurde.
The pair of bearing rings 28 is accommodated in the frame 5, as is shown in detail in FIG. 4.
Cross members 5b are connected to the longitudinal member 5a of the frame 5.
The crossbeams 5b receive bearing rollers 30 which support the rotationally driven bearing rings 28, 29.
The drive of the individual bearing rings 28, 29 will not be discussed further here, since this was already described in detail in the previously known DE-OS 41 23 477 A1.

Wie Fig. 1 zeigt, sind die einzelnen Quetschwerke 13 im Vergleich zur Längsachse des zentralen Trägers 19 schräg gestellt. Diese Schrägstellung gewährleistet ein sogenanntes rundum Abquetschen und gleichzeitig den Transport der abgequetschten Schlauch-Wirkware 1 in Richtung der Walzenanordnung 16 gem. Fig. 1.As shown in FIG. 1, the individual crushing units 13 are inclined in comparison to the longitudinal axis of the central carrier 19. This inclination ensures a so-called all-round squeezing and at the same time the transport of the squeezed tubular knitted fabric 1 in the direction of the roller arrangement 16 according to. Fig. 1.

Erfindungswesentlich ist also, daß die Quetschwalzenpaare 23 stationär und drehend gelagert am zentralen Träger 19 angeordnet sind und wenigstens je ein Breithalteelement 12, wie an sich bekannt, an den freien Enden der radial schwenkbaren Abstützungen 20,21 vorgesehen ist.It is essential to the invention that the nip roller pairs 23 are arranged in a stationary and rotating manner on the central support 19 and at least one holding element 12, as is known per se, is provided on the free ends of the radially pivotable supports 20, 21.
