Description
Die Erfindung betrifft eine Frottierwebmaschine, die auf der Basis einer oszillierenden Verschiebung der Anschlagkante eines herzustellenden Gewebes im Rhythmus und synchron mit dem Antrieb eines Webblattes arbeitet.The invention relates to a terry weaving machine that works on the basis of an oscillating displacement of the stop edge of a fabric to be produced in rhythm and synchronously with the drive of a reed.
Zur Herstellung von Frottierware auf Webmaschinen sind mehrere Verfahrenswege und Vorrichtungen zu deren Durchführung bekannt.
So zum Beispiel kann die Florbildung mittels der sogenannten Webladensteuerung gemäß der Erfindung nach dem EP 0 298 454 B1 erfolgen. Darauf soll nachfolgend nicht näher eingegangen werden, weil Grundlage der zu offenbarenden erfinderischen Lösung die sogenannte Gewebesteuerung ist.
Aus der EP 0 298 454 B1 ist aber bekannt, daß während des Webprozesses bei der Herstellung von Frottiergewebe variierbare Florhöhen realisiert werden können. Dazu steht die Webladenwelle über entsprechende getriebliche Mittel mit einem vom Webmaschinenantrieb unabhängigen Servoantrieb in Verbindung, der frei und einzelschußweise ansteuerbar ist.
Durch die einzelschußweise Ansteuerung des separaten Antriebes ist jeder beliebige Frottierrhythmus erreich- und in beliebiger Folge wechselbar.For the production of terry goods on weaving machines, several process routes and devices for carrying them out are known.
For example, the pile formation can take place by means of the so-called weaving shop control according to the invention according to EP 0 298 454 B1. This will not be discussed in more detail below, because the basis of the inventive solution to be disclosed is the so-called tissue control.
However, it is known from EP 0 298 454 B1 that variable pile heights can be achieved during the weaving process in the production of terry cloth. For this purpose, the shaft of the loom is connected to a servo drive which is independent of the loom drive and which can be controlled freely and in individual wefts.
Through the individual shot control of the separate drive, any terry rhythm can be reached and changed in any order.
Zur Herstellung von Frottierware mit variabler Florhöhe mittels der sogenannten Gewebesteuerung hat die Anmelderin eine Frottierwebmaschine als Prototyp gefertigt, die einen separaten und vom Webmaschinenantrieb unabhängigen Antrieb zur freien und einzelschußweisen Steuerung besitzt, der mit Übertragungselementen zur Veränderung der Florhöhe während des Webprozesses in Verbindung steht. Diese Übertragungselemente, die auf die Florbildeorgane wirken, steuern die Bewegung des Gewebes und die der Grundkette.
Als separat steuerbarer Antrieb wurde ein hydraulischer Linearverstärker mit integraler Proportionalregelung verwendet.For the production of terry goods with variable pile height by means of the so-called fabric control, the applicant has produced a terry weaving machine as a prototype, which has a separate drive for free and single-weft control that is independent of the loom drive and is connected to transmission elements for changing the pile height during the weaving process. These transmission elements, which act on the pile organs, control the movement of the fabric and that of the basic chain.
A hydraulic linear amplifier with integral proportional control was used as a separately controllable drive.
Mittels der elektronischen Steuerung konnte die Florhöhe bedarfsgerecht vorgegeben und auch ein Glattweben für Bordüren realisiert werden.Using the electronic control, the pile height could be specified as required and smooth weaving for borders could also be realized.
Aus der EP 0 350 446 B1 ist ein Frottierwebverfahren und eine Webmaschine mit Florbildeorganen bekannt, wobei die Webmaschine Vorkehrungen aufweist, um nach dem Prinzip der Webladensteuerung Frottiergewebe mit variabler Florhöhe zu realisieren.
Des weiteren offenbart die EP 0 350 446 B1 eine Webmaschine, die nach dem Prinzip der Gewebesteuerung Frottiergewebe mit variabler Florhöhe realisiert.
Zur Florhöhenveränderung ist wenigstens ein Florbildeorgan durch einen separaten Antrieb betätigt, der einzelschußweise und frei ansteuerbar ist.
Als separater Antrieb wird ein Servomotor vorgeschlagen, der über ein Untersetzungsgetriebe und/oder Übertragungselemente mit mindestens einem Florbildeorgan gekoppelt ist.From EP 0 350 446 B1 a terry weaving method and a weaving machine with pile forming elements are known, the weaving machine having arrangements to realize terry fabrics with a variable pile height according to the principle of the weaving shop control.
Furthermore, EP 0 350 446 B1 discloses a weaving machine which realizes terry fabrics with a variable pile height according to the principle of fabric control.
To change the pile height, at least one pile forming element is actuated by a separate drive, which can be controlled individually and individually.
A servo motor is proposed as a separate drive, which is coupled to at least one pile forming element via a reduction gear and / or transmission elements.
Des weiteren ist aus der DE 44 32 452 A1 eine Frottierwebmaschine mit einer Frottiereinrichtung zur kontinuierlichen Veränderung der Florhöhe während des Webens bekannt. Hier erfolgt die Frottierbildung ebenfalls auf der Grundlage der sogenannten Gewebesteuerung, d.h. die Schußfaden-Anschlagkante des Gewebes erfährt im Rhythmus und synchron zur Schußfaden-Anschlagbewegung des Webblattes eine Verschiebung hin zur Anschlagposition des Webblattes und weg von dieser.
Die Frottierbildeeinrichtung besteht aus einem Kugelspindelmechanismus, der zur Drehrichtungsumkehr der Kugelspindel mit einem mustersteuerbaren motorischen Antrieb in Verbindung steht. An dem Mechanismus ist ein drehbeweglich gelagerter Winkelhebel mit einem seiner Hebelarme angelenkt. Der andere Hebelarm ist über eine Koppel mit einem sogenannten drehbar gelagerten Zwischenhebel verbunden, der neben einem Hebel zur Anlenkung der vom Winkelhebel ausgehenden Koppel, zwei weitere Hebelarme aufweist.
An einem der weiteren Hebelarme ist eine zweite Koppel angelenkt, die mit einem die Gewebeverschiebung bewirkenden Bauteil verbunden ist, während an dem anderen weiteren Hebelarm eine dritte Koppel angelenkt ist, die auf ein die Polkettspannung beeinflussendes Bauteil wirkt.Furthermore, from DE 44 32 452 A1 a terry weaving machine with a terry device for continuously changing the pile height during weaving is known. Here the terry formation also takes place on the basis of the so-called fabric control, ie the weft stop edge of the fabric undergoes a shift towards and away from the reed position of the reed in rhythm and in synchronism with the weft stop movement of the reed.
The terry formation device consists of a ball screw mechanism, which is connected to a pattern-controllable motor drive to reverse the direction of rotation of the ball screw. A rotatably mounted angle lever is articulated to the mechanism with one of its lever arms. The other lever arm is connected via a coupling to a so-called rotatably mounted intermediate lever which, in addition to a lever for articulating the coupling originating from the angle lever, has two further lever arms.
A second coupling is articulated on one of the further lever arms, which is connected to a component causing the tissue displacement, while on the another lever arm a third coupling is articulated, which acts on a component influencing the chain voltage.
Bei allen vorbekannten Webmaschinen zur Herstellung von Frottiergewebe beruht die Ausbildung einer variablen Florhöhe auf einen unabhängig vom Webmaschinen-Hauptantrieb gesteuerten Servomotor, der mit Organen zur Gewebeverschiebung oder mit Organen zur Verstellung der Anschlagposition des Webblattes in Verbindung steht.
Ein solcher Servomotor erfordert eine hohe Antriebsleistung zur Ausführung der Frottierbewegung.
Keiner der bekannten Webmaschinen liegt also eine Vorrichtung in Art eines vom Webmaschinen-Hauptantrieb abgeleiteten Exzenterantriebes zugrunde, der mit Organen zur Gewebeverschiebung zum Zwecke der Ausbildung einer bestimmten Florhöhe in Verbindung steht.
Hier setzt die Erfindung an.In all previously known looms for the production of terry fabrics, the formation of a variable pile height is based on a servo motor which is controlled independently of the loom main drive and which is connected to organs for tissue displacement or with organs for adjusting the stop position of the reed.
Such a servomotor requires a high drive power to carry out the terry movement.
None of the known weaving machines is therefore based on a device in the manner of an eccentric drive derived from the weaving machine main drive, which is connected to organs for tissue displacement for the purpose of forming a certain pile height.
This is where the invention comes in.

Erfindungswesentlich ist danach, daß bei einer mit einer Grundflorbildeeinrichtung ausgerüsteten Webmaschine, die auf der Grundlage der sogenannten Gewebesteuerung arbeitet, in einem die Frottierbewegung übertragenden Mechanismus eine Florhöhenverstelleinrichtung eingebunden ist.The object is achieved by the features of
It is essential to the invention that a pile height adjustment device is integrated in a weaving machine equipped with a basic pile forming device, which works on the basis of the so-called fabric control, in a mechanism that transmits the terry movement.
