Abstract

Bekannte ungesteuerte Spanneinheiten für die Webkette sind relativ verwindungssteif ausgebildet. Zur Verarbeitung von reißempfindlichen Webketten sind derartige Spanneinheiten ungeeignet. Wesentliche Aufgabe der Erfindung ist es daher, ein Spanneinheit zu schaffen, in welcher, bei gegebenenfalls unterschiedlicher Belastung der Streichwalze, ein Drehmomentenausgleich in der Spanneinheit bewirkt wird. Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß eine von starr befestigten Hebeln 9 getragene Umlenkwalze 11 eine Stabilisatorwelle 18 drehbeweglich aufnimmt und die Stabilisatorwelle 18 mit einer von federbelasteten Hebeln 8 getragenen Streichwalze 10 über Laschen 19 wirkverbunden ist. <IMAGE>Known uncontrolled tensioning units for the warp are designed to be relatively torsionally rigid. Such tensioning units are unsuitable for processing tear-sensitive warps. It is therefore an essential object of the invention to provide a tensioning unit in which, if the load on the coating roller is different, torque compensation is effected in the tensioning unit. According to the invention the object is achieved in that a deflection roller 11 carried by rigidly attached levers 9 rotatably receives a stabilizer shaft 18 and the stabilizer shaft 18 is operatively connected to a coating roller 10 carried by spring-loaded levers 8 via tabs 19. <IMAGE>

Description

Die Erfindung betrifft eine ungesteuerte Spanneinheit einer Webmaschine für eine aus reißempfindlichen Kettfäden bestehenden Webkette.The invention relates to an uncontrolled tensioning unit of a weaving machine for a weaving chain consisting of tear-sensitive warp threads.

Aus der EP-Anmeldung 0 396 501 ist eine Webmaschine mit einer leichtgängigen Spannvorrichtung für die Webkette bekannt.
Die Aufgabe der Spannvorrichtung besteht hier darin, ein leichtgängig angetriebenes Spannsystem für eine Webkette zu schaffen, das auch für schweres Gewebe geeignet ist und sensibel auf Spannungsschwankungen in der Kette bzw. auf Positionsänderungen im Antrieb des Systems reagiert.
Gelöst wird die Aufgabe dadurch, daß ein Verstellmechanismus, bestehend aus einer längeneinstellbaren Schubstange, die mit einem vom Hauptantrieb der Webmaschine abgeleiteten Antrieb in Verbindung steht und der Verstellmechanismus auf eine mit einer Antriebswelle in Verbindung stehenden Feder wirkt, die als Torsionsstab ausgebildet ist.
Die mit dem Torsionsstab wirkverbundene Antriebswelle trägt in über die Webbreite verteilten Lagerstellen eine rotationssymmetrisch ausgebildete Streich- oder Spannwalze.A weaving machine with a smooth-running tensioning device for the warp is known from EP application 0 396 501.
The task of the tensioning device here is to create a smoothly driven tensioning system for a warp that is also suitable for heavy fabrics and is sensitive to tension fluctuations in the warp or changes in position in the drive of the system.
The object is achieved in that an adjusting mechanism, consisting of a length-adjustable push rod, which is connected to a drive derived from the main drive of the loom and the adjusting mechanism acts on a spring connected to a drive shaft, which is designed as a torsion bar.
The drive shaft, which is operatively connected to the torsion bar, carries a rotationally symmetrical coating or tensioning roller in bearing points distributed over the weaving width.

Aus der europäischen Patentanmeldung 0 109 472 ist eine Einrichtung zum Spannen der Webkette bekannt, die ebenfalls aus einen mit einem Antrieb in Verbindungen stehenden Torsionsfederstab besteht, der in einer als Hohlwelle ausgebildeten und die Streichwalze oder Spannwalze stützenden Tragbaum angeordnet ist.From the European patent application 0 109 472 a device for tensioning the warp is known, which also consists of a torsion spring rod connected to a drive, which is arranged in a hollow shaft designed as a hollow shaft and supporting the coating roller or tension roller.

Nachteilig bei derartigen die Kettspannung beeinflussenden Spanneinheiten ist ihr kostenaufwendiger Aufbau und der nicht unerhebliche Montage- bzw. Demontageaufwand im Falle einer auf dieser Einheit beruhenden Funktionsstörung.Disadvantages of such tensioning units influencing the warp tension are their expensive construction and the not inconsiderable assembly and disassembly effort in the event of a malfunction based on this unit.

Aufgabe der Erfindung ist es, eine ungesteuerte Spanneinheit für reißempfindliche Kettfäden einer Webkette zu schaffen, mit der auf einfache Weise die Webkette gespannt werden kann, in der die Streich- und Umlenkwalze massearm ausgebildet ist, die auf einen konventionellen Tragbaum, auf dem sich die Streichwalze abstützt, verzichtet, in der die Streich- und die Umlenkwalze lose getragen ist, die im Hinblick auf webtechnische Bedingungen in der vertikalen und horizontalen Ebene positionierbar ist und die einen Drehmomentenausgleich in der Spanneinheit bei gegebenenfalls unterschiedlicher Belastung der Streichwalze ermöglicht.The object of the invention is to provide an uncontrolled tensioning unit for tear-sensitive warp threads of a warp, with which the warp can be tensioned in a simple manner, in which the coating and deflecting roller is designed with low mass, on a conventional support beam on which the coating roller supports, dispenses, in which the coating and the deflection roller is loosely carried, which can be positioned in terms of weaving conditions in the vertical and horizontal plane and which enables a torque compensation in the tensioning unit with possibly different loading of the coating roller.

Erfindungsgemäß wird die Aufgabe durch die kennzeichnenden Merkmale von Patentanspruch 1 gelöst.According to the invention the object is achieved by the characterizing features of claim 1.

Die Erfindung soll nachstehend an einem Ausführungsbeispiel näher erläutert werden:
Es zeigen:

Figur 1:
die Anordnung der Spanneinheit an der einen Seitenwange der Webmaschine in perspektivischer Darstellung,
Figur 2:
in schematischer Darstellung die Vorkehrungen zum Drehmomenten ausgleich innerhalb der Spanneinheit.
The invention will be explained in more detail below using an exemplary embodiment:
Show it:
Figure 1:
the arrangement of the tensioning unit on one side cheek of the weaving machine in a perspective view,
Figure 2:
in a schematic representation, the precautions for torque compensation within the clamping unit.

Die Spanneinheit 1 besteht unter anderem aus einem Querträger 2, der mit einem ersten linken und einem ersten rechten Bauteil 3 festverbunden ist. Die Bauteile 3 sind verschiebbar in einem weiteren linken und einem weiteren rechten Bauteil 4 getragen.
Das Bauteil 4 ist schwenkbeweglich mit der jeweiligen Seitenwand 5 verbunden und durch nicht dargestellte Verbindungselemente über die Langlöcher 5a und z.B. hier nicht sichtbare Gewindelöcher an der Seitenwand 5 arretierbar.
Jedes Bauteil 4 bildet zur Verbindung mit dem jeweiligen Bauteil 3 eine Längsnut 4a und Langlöcher 4b aus, vermittels derer und mittels durch nicht dargestellte Verbindungselemente das Bauteil 3 am Bauteil 4 in einem gewünschten Abstand zu den nicht gezeigten Fach- und Gewebebildeorganen positioniert werden kann.The clamping unit 1 consists, among other things, of a cross member 2 which is firmly connected to a first left and a first right component 3. The components 3 are slidably carried in a further left and a further right component 4.
The component 4 is pivotally connected to the respective side wall 5 and can be locked on the side wall 5 by connecting elements (not shown) via the elongated holes 5a and, for example, threaded holes not visible here.
Each component 4 forms a longitudinal groove 4a and elongated holes 4b for connection to the respective component 3, by means of which and by means of connecting elements, not shown, the component 3 on the component 4 at a desired distance can be positioned to the technical and tissue imaging organs, not shown.

An dem Querträger 2 sind über seine Länge mehrere Lagerschilde 6, wenigstens jedoch ein erstes äußeres und ein zweites äußeres Lagerschild 6, angeordnet. Alle Lagerschilde 6 liegen in einer gemeinsamen Anordnungsebene.A plurality of end shields 6, but at least a first outer and a second outer end shield 6, are arranged on the cross member 2 over its length. All end shields 6 lie in a common arrangement level.

Die einzelnen Lagerschilde 6 nehmen an ihrem freien Ende einen schwenkbar um eine Drehachse 7 angeordneten Hebel 8 und parallel dazu einen drehfest angeordneten Hebel 9 auf.
Beide Hebel bilden ein Rollenlager 8a, 9a aus.
In dem Rollenlager 8a der schwenkbar angeordneten Hebel 8 ist lose die Streichwalze 10 und in dem Rollenlager 9a des drehfesten Hebels 9 ist lose die Umlenkwalze 11 getragen.The individual end shields 6 receive at their free end a lever 8 arranged pivotably about an axis of rotation 7 and parallel to it a lever 9 arranged in a rotationally fixed manner.
Both levers form a roller bearing 8a, 9a.
The roller roller 10 is loosely carried in the roller bearing 8a of the pivotably arranged lever 8 and the deflection roller 11 is loosely carried in the roller bearing 9a of the non-rotatable lever 9.

Alle Lagerschilde 6 sind im Bereich ihrer Verbindung mit dem Querträger 2 quer von einer um ihre Längsachse 12a verstellbaren Welle 12 durchgriffen oder die Welle 12 ist in entsprechenden Lagern aufgenommen und z.B. mit wenigsens einem der Lagerschilde 6 arretierend verbindbar.All bearing plates 6 are penetrated transversely in the area of their connection to the cross member 2 by a shaft 12 adjustable about their longitudinal axis 12a or the shaft 12 is received in corresponding bearings and e.g. connectable with at least one of the end shields 6 in a locking manner.

Auf dem Umfang der Welle 12 sind, entsprechend der Anordnungsposition der schwenkbar gelagerten Hebel 8 Anlenkelemente 13 klemmend verbunden. An jedem Anlenkelement 13 greift das eine Ende eines Federelementes 14 an. Das andere Ende des Federelementes 14 ist an einem Hebelarm 8b des Hebels 8 angelenkt.
Zwischen der verstellbaren Welle 12 und dem jeweiligen Hebel 8 besteht dabei über das jeweilige Federelement 14 eine kraftschlüssige Verbindung.On the circumference of the shaft 12, 8 articulation elements 13 are connected in a clamped manner in accordance with the arrangement position of the pivotably mounted levers. One end of a spring element 14 engages on each articulation element 13. The other end of the spring element 14 is articulated on a lever arm 8b of the lever 8.
There is a non-positive connection between the adjustable shaft 12 and the respective lever 8 via the respective spring element 14.

Durch Verdrehen der Welle 12 um ihre Längsachse 12a sind alle Hebel 8 und damit die in den Rollenlagern 8a getragene Streichwalze 10 positionsveränderbar. Die Spannung der Streichwalze 10 ist somit auf die aus reißempfindlichen Kettfäden bestehenden Webkette 15 feinfühlig einstellbar.By rotating the shaft 12 about its longitudinal axis 12a, all levers 8 and thus the coating roller 10 carried in the roller bearings 8a can be changed in position. The tension of the coating roller 10 can thus be finely adjusted to the warp 15 consisting of tear-sensitive warp threads.

Die Spanneinheit 1 besitzt ferner einen Drehmomentenausgleich, um gegebenenfalls eine asymmetrische Belastung der Webkette 15 auszuschließen.
Dazu ist erfindungsgemäß vorgesehen, wie Figur 2 im Detail zeigt, daß in die beiden freien Enden der Streichwalze 10 ein einen Walzenzapfen 10a tragendes Rollenlager eingesetzt ist.
In den freien Enden der Umlenkwalze 11 ist ebenfalls ein Rollenlager 17 integriert, welches eine sogenannte, die Umlenkwalze berührungslos durchgreifende Stabilisatorwelle 18 an ihren Wellenzapfen 18a drehbeweglich aufnimmt.
Eine Lasche 19 stellt zwischen der drehbeweglich gelagerten Stabilisatorwelle 18 und dem jeweiligen Walzenzapfen 10a eine Wirkverbindung her.
Die Verbindung zwischen den Walzenzapfen 10a und der Lasche 19 ist dabei so ausgeführt, daß die Lasche 19 eine Längsführung 19a aufweist, in die der Walzenzapfen 10a, welcher entsprechende Führungsflächen 10b besitzt, eingreift.
Andererseits besteht zwischen dem jeweiligen Wellenzapfen 18a und der Lasche 19 eine formschlüssige Verbindung, z.B. eine Schraubverbindung 20.
Durch eine solche Ausbildung wird bei asymmetrischer Belastung der Spanneinheit 1 über die Stabilisatorwelle 18 ein Drehmomentenausgleich in der Spanneinheit 1 erreicht.The tensioning unit 1 also has a torque compensation in order to rule out any asymmetrical loading on the warp 15.
For this purpose, according to the invention, as FIG. 2 shows in detail, a roller bearing carrying a roll neck 10a is inserted into the two free ends of the coating roller 10.
In the free ends of the deflection roller 11, a roller bearing 17 is also integrated, which rotatably receives a so-called stabilizer shaft 18, which passes through the deflection roller without contact, on its shaft journal 18a.
A tab 19 establishes an operative connection between the rotatably mounted stabilizer shaft 18 and the respective roll neck 10a.
The connection between the roll neck 10a and the tab 19 is carried out in such a way that the tab 19 has a longitudinal guide 19a into which the roll neck 10a, which has corresponding guide surfaces 10b, engages.
On the other hand, there is a positive connection, for example a screw connection 20, between the respective shaft journal 18a and the tab 19.
Such a design achieves a torque compensation in the tensioning unit 1 when the tensioning unit 1 is loaded asymmetrically via the stabilizer shaft 18.
