Description

Die Erfindung betrifft eine Webmaschine mit einem Eintragungssystem für eine Mehrzahl von in der Regel unterschiedlichen Schussfäden gemäss dem Oberbegriff des Anspruches 1 ( EP-A-0 461 524 ).The invention relates to a weaving machine with a registration system for a plurality of generally different weft threads according to the preamble of claim 1 (US Pat. EP-A-0 461 524 ).

Zum Eintragen einer Mehrzahl von Schussfäden sind Systeme bekannt, die für jeden Schussfaden mindestens einen Fadenvorrat, einen Fadenspeicher mit auf der Fadenabzugsseite integrierter Bremse z.B. in Form eines Bürstenringes, einen Fadenwächter, eine Fadenbremse, und einen Fadenvorleger als Teil eines Farbwählers sowie einen Greifer umfassen. Die Schussfäden verlaufen vom Fadenvorrat über den Fadenspeicher, den Fadenwächter, die Fadenbremse und dem Fadenvorleger entweder in das Gewebe, in welchem der Schussfaden eingebunden ist oder in eine Fadenklemme, in welche der Schussfaden gehalten ist. Zum Eintragen eines Schussfadens wird dieser durch den Fadenvorleger in die Laufbahn des Greifers verlagert und vom Greifer aufgenommen. Der eingebundene Schussfaden wird abgeschnitten und in das geöffnete Webfach eingetragen. Der geklemmte Schussfaden wird eingetragen und angeschlagen sowie nach der Klemmstelle abgeschnitten.For introducing a plurality of weft threads, systems are known which, for each weft thread, have at least one thread supply, a thread store with brake integrated on the take-off side, e.g. in the form of a brush ring, a thread monitor, a thread brake, and a thread rug as part of a color selector and a gripper include. The weft threads extend from the thread supply via the thread store, the thread monitor, the thread brake and the thread rug either into the fabric in which the weft thread is incorporated or into a thread clamp in which the weft thread is held. To enter a weft thread this is displaced by the thread rug into the raceway of the gripper and received by the gripper. The wrapped weft thread is cut off and entered into the open shed. The clamped weft thread is entered and struck and cut off after the nip.

Als nachteilig erweist sich bei diesem Eintragungssystem, dass für jeden Schussfaden ein Fadenwächter und mindestens eine Fadenbremse vorgesehen ist, in welche der eingezogene Schussfaden stets verbleibt. Durch den Abrieb wird die Fadenbremse verschmutzt, so dass die Fadenbremse periodisch gereinigt werden muss, um Fadenbrüche zu vermeiden.A disadvantage of this registration system proves that for each weft yarn thread monitor and at least one yarn brake is provided, in which the retracted weft thread always remains. As a result of the abrasion, the thread brake becomes dirty, so that the thread brake has to be cleaned periodically in order to avoid yarn breaks.

Der Erfindung, liegt die Aufgabe zugrunde eine Webmaschine mit einem vereinfachten und betriebssicheren Eintragungssystem zu schaffen.The invention has for its object to provide a loom with a simplified and reliable registration system.

Diese Aufgabe wird erfindungsgemäss durch die kennzeichnenden Merkmale des Anspruches 1 gelöst.This object is achieved according to the invention by the characterizing features of claim 1.

Bei dem Eintragungssystem mit einem Fadenvorrat, einem Fadenspeicher, einem Farbwähler und einem Greifer verlaufen die Schussfäden ausgehend vom Fadenvorrat über den Fadenspeicher und den Fadenvorleger des Farbwählers in das Gewebe. Hierbei wird auf die sonst übliche Fadenführung zwischen Fadenspeicher und Farbwähler verzichtet, so dass lediglich eine durch den Fadenvorleger gebildete Reibstelle vorhanden ist. Der Farbwähler legt mittels eines Fadenvorleger jeweils einen Schussfaden dem Greifer vor, welcher den Schussfaden übernimmt und in das offene Webfach einträgt. Es wird lediglich eine Fadenbremse vorgesehen, um den jeweils vorgelegten Schussfaden zu bremsen. Weil jeder Schussfaden in die Fadenbremse hineingezogen wird, reinigt sich die Fadenbremse selbst.In the registration system with a thread supply, a thread store, a color picker and a gripper, the weft threads extend from the thread supply via the thread store and the thread rollover of the color selector in the tissue. Here is dispensed with the usual thread guide between yarn store and color selector, so that only a friction point formed by the thread rug is present. The color selector sets by means of a thread rug in each case a weft before the gripper, which takes over the weft and enters into the open shed. It is merely a thread brake provided to brake the respectively presented weft. Because each weft thread is pulled into the thread brake, the thread brake cleans itself.

Nachfolgend wird die Erfindung anhand der beiliegenden Zeichnungen erläutert, welche Ausführungen in schematischer Darstellung sind.The invention will be explained with reference to the accompanying drawings, which are embodiments in a schematic representation.

Die Ausführungsbeispiele nach den Figuren 1, 4 und 5, welche nicht unter den Schutzumfang der Ansprüche fallen, erleichtern jedoch das Verständnis der beanspruchten Erfindung.The embodiments of the FIGS. 1 . 4 and 5 However, which do not fall within the scope of the claims, facilitate the understanding of the claimed invention.

Es wird auf die Figuren 1 und 2 Bezug genommen. Die Figuren zeigen eine Ausführung eines Eintragungssystems mit dem z.B. vier Schussfäden mit z.B. unterschiedlicher Farbe bzw. Dicke und/oder Struktur eingetragen werden. Das Eintragungssystem enthält für jeden Schussfaden 1 eine Vorratsspule 2, einen Fadenspeicher 3 mit auf der Fadenabzugsseite integrierter Bremse z.B. in Form eines Bürstenringes und einen Farbwähler 4 mit vier Fadenvorleger 5 sowie für alle vier Schussfäden gemeinsam Führungsorgane 6 zur Beruhigung des vorgelegten Schussfadens, die im Wirkungsbereich der Fadenvorleger 5 angeordnet sind als auch eine Fadenbremse 7, einen Sensor 8, mit welchem die Fadenzugkraft gemessen und der einzutragenden Schussfaden überwacht wird und einen Fadenwächter 9 zum Feststellen eines unbeabsichtigten Doppelschusses, die in Laufrichtung des Fadens dem Farbwähler 4 nachgeordnet sind und einen Greifer 10. Die Vorratsspulen 2, die Fadenspeicher 3 und der Farbwähler 4 sind in bekannter Weise an der Webmaschine angeordnet. Die Führungsorgane 6, die Fadenbremse 7, der Sensor 8 und der Fadenwächter 9 sind an einem Führungsteil 11 für den Greifer angeordnet. Die Führungsorgane 6 sind als Stifte ausgebildet. Die Fadenvorleger 5, die Fadenbremse 7, der Sensor 8 und der Fadenwächter 9 sind mit einer Steuereinrichtung (nicht dargestellt) der Webmaschine signalübertragend verbunden, um die Eintragung zu steuern.It will be on the Figures 1 and 2 Referenced. The figures show an embodiment of a registration system with, for example, four weft threads are entered with eg different color or thickness and / or structure. The registration system contains for each weft thread 1 a supply reel 2, a yarn store 3 integrated on the yarn withdrawal side brake eg in the form of a brush ring and a color picker 4 with four thread rugs 5 and for all four weft threads together guide members 6 to calm the submitted weft thread, in the area of action the thread ripper 5 are arranged as well as a yarn brake 7, a sensor 8, with which the yarn tension measured and monitored weft thread is monitored and a thread monitor 9 for detecting an unintentional double shot, which are arranged downstream of the color picker 4 in the direction of the thread and a gripper 10th The supply reels 2, the yarn stores 3 and the color picker 4 are arranged in a known manner on the weaving machine. The guide members 6, the thread brake 7, the sensor 8 and the thread monitor 9 are arranged on a guide part 11 for the gripper. The guide members 6 are formed as pins. The thread rugs 5, the thread brake 7, the sensor 8 and the thread monitor 9 are signal-transmitting connected to a control device (not shown) of the loom to control the entry.

Zu Beginn der Eintragung sind die Schussfäden 1 in einer Haltestellung (Fig.1), wobei diese ausgehend vom Fadenspeicher 3 über den Fadenvorleger 4 in das Gewebe 11A verlaufen und ausserhalb der Laufbahn des Greifers gehalten sind. Zum Eintragen wird aufgrund eines Steuerbefehls der entsprechende Fadenvorleger 4 den in das Webfach einzutragenden Schussfaden aus der Haltestellung in eine Übergabestellung verlagern. In dieser Übergabestellung kreuzt der Schussfaden 1 die Laufbahn des Greifers. Gleichzeitig wird der Schussfaden an die Führungsorgane 6 angelegt, um den Schussfaden zu beruhigen. Während der Bewegung in das durch die Kettfäden 12 gebildete Webfach 14 nimmt der Greifer mit seiner Fadenklemme 15 den vorgelegten Schussfaden auf. Hierbei wird der im Gewebe abgebundene Schussfaden in den Klemmspalt der Fadenklemme eingeführt, so dass der Schussfaden in der Fadenklemme gehalten wird (Fig.2). Im weiteren Verlauf der Bewegung des Greifers wird einerseits mittels des Fadenwächters 9 der Schussfaden abgetastet und andererseits der Schussfaden in den Bremsspalt der Fadenbremse 7 hineingezogen. Anschliessend wird der Schussfaden im Bereich des Geweberandes mittels einer Schneidvorrichtung geschnitten. Schliesslich wird der Schussfaden mit dem Sensor 8 in Kontakt gebracht, um den Verlauf der Fadenzugkraft während der Eintragung des Schussfadens zu messen und gegebenenfalls im gleichen oder einem nachfolgenden Eintragszyklus bedarfsweise zu verändern und den Schussfaden zu überwachen, um beispielsweise einen Fadenbruch festzustellen und um ein Webmaschinenstoppsignal abzugeben.At the beginning of the registration, the weft threads 1 are in a holding position ( Fig.1 ), which extend from the yarn store 3 on the thread rug 4 in the fabric 11A and are held outside the career of the gripper. For entry, due to a control command, the corresponding thread rug 4 will shift the weft thread to be inserted into the shed from the holding position into a transfer position. In this transfer position, the weft thread 1 crosses the raceway of the gripper. At the same time, the weft thread is applied to the guide members 6 to calm the weft. During movement into the shed 14 formed by the warp threads 12, the gripper with its thread clamp 15 picks up the weft thread presented. In this case, the weft thread tied in the fabric is introduced into the nip of the thread clamp, so that the weft thread is held in the thread clamp ( Fig.2 ). In the further course of the movement of the gripper is on the one hand means the thread monitor 9 scanned the weft and on the other hand, the weft thread pulled into the brake gap of the yarn brake 7. Subsequently, the weft thread is cut in the region of the fabric edge by means of a cutting device. Finally, the weft yarn is brought into contact with the sensor 8 to measure the course of the yarn tension during the entry of the weft yarn and optionally in the same or a subsequent entry cycle as needed to change and monitor the weft thread, for example, to determine a yarn break and a weaving machine stop signal leave.

Die in Fig.3 gezeigte Ausführung unterscheidet sich von der Ausführung nach Fig.1 dadurch, dass neben der ersten Fadenbremse 7 eine zweite Fadenbremse 21 vorgesehen ist, um z.B. die Bremswirkung zu erhöhen und/oder um die Bremskraft auf einen längeren Fadenabschnitt zu verteilen. Diese Fadenbremse ist mit Führungsbügel 22 versehen, um den vorzulegenden Schussfaden sicher in die Fadenbremse 21 einzuführen.In the Figure 3 The design shown differs from the design Fig.1 in that, in addition to the first yarn brake 7, a second yarn brake 21 is provided in order, for example, to increase the braking effect and / or to distribute the braking force over a longer yarn section. This yarn brake is provided with guide bracket 22 to introduce the weft yarn to be presented safely in the yarn brake 21.

Die Fig.4 zeigt eine dritte Ausführung eines Eintragungssystems. Diese Ausführung unterscheidet sich von nach Fig. 1 und 2 dadurch, dass die Fadenbremse 7 an der Weblade angeordnet ist. Der Vorteil dieser Lösung besteht darin, dass die Wirkung der Fadenbremse bis zum Zeitpunkt des Blattanschlages aufrechterhalten wird.The Figure 4 shows a third embodiment of a registration system. This version is different from Fig. 1 and 2 in that the yarn brake 7 is arranged on the batten. The advantage of this solution is that the effect of the thread brake is maintained until the time of leaf strike.

Die Fig.5 zeigt eine Ausführung mit einer Umschlingungsreibungsbremse. Diese Fadenbremse 25 wird aus zwei Bremsstiften 26 und dem jeweiligen Fadenvorleger 5 gebildet, welcher einen ausgewählten Schussfaden vorlegt. Diese Ausführung stellt die einfachste Lösung dar, mit welcher neben der Vorlagefunktion auch die Bremsfunktion ausführbar ist. Dabei wird die Grösse der Umschlingung und somit die Bremswirkung über das Mass des Tiefganges des Fadenvorlegers in Relation zu den Bremsstiften steuerbar.The Figure 5 shows an embodiment with a wrap friction brake. This yarn brake 25 is formed from two brake pins 26 and the respective thread rug 5, which presents a selected weft. This version represents the simplest solution, with which in addition to the template function and the braking function is executable. In this case, the size of the loop and thus the braking effect on the amount of draft of the thread roving in relation to the brake pins controllable.

Die Fig.6 zeigt eine modifizierte Ausführung der Fadenbremse nach Fig.5. Die Fadenbremse 27 enthält zwei ortsfeste Bügel 28, die im Abstand zueinander am Führungsteil 11 für den Greifer montiert sind und einen linear beweglichen Bügel 29, der mit einem Stellmotor 30 verbunden und relativ zu den ortsfesten Bügeln 28 verstellbar ist. Es versteht sich von selbst, dass auch mehrere sowohl feststehende, als auch bewegliche Bügel vorgesehen werden können, mit z.B. dem Verteil eines verringerten Hubes.The Figure 6 shows a modified version of the yarn brake after Figure 5 , The yarn brake 27 includes two fixed bracket 28, which are mounted at a distance from each other on the guide member 11 for the gripper and a linearly movable bracket 29 which is connected to a servomotor 30 and relative to the fixed brackets 28 is adjustable. It goes without saying that several fixed as well as movable bracket can be provided with, for example, the distribution of a reduced stroke.

Bei den vorstehend beschriebenen Ausführungen können generell unterschiedliche Ausführungsformen von Fadenbremsen, z.B. solche mit automatischer Einstellung der Bremskraft oder mit einer Bremskraftregelung angewendet werden, die elektrisch, pneumatisch oder in sonstiger geeigneter Form betrieben werden.In the embodiments described above, different embodiments of yarn brakes, e.g. those with automatic adjustment of the braking force or with a braking force control can be applied, which are operated electrically, pneumatically or in any other suitable form.

Die Webmaschine enthält ein Eintragungssystem für eine Mehrzahl von in der Regel unterschiedlichen Schussfäden, welches für jeden Schussfaden einen Fadenvorrat 2, einen Fadenspeicher 3 und einen Farbwähler 4 zum wahlweisen Vorlegen der Schussfäden sowie einen Greifer 10 zum Eintragen des vorgelegten Schussfadens umfasst. Es ist mindestens eine für sämtliche Schussfäden gemeinsame Fadenbremse 7 vorgesehen, um den jeweils vorgelegten Schussfaden 1 während der Eintragung bedarfsweise zu bremsen.The weaving machine includes a registration system for a plurality of generally different weft threads, which comprises a thread supply 2, a yarn store 3 and a color picker 4 for selectively presenting the weft threads and a gripper 10 for entering the weft thread presented for each weft. At least one thread brake 7 common to all the weft threads is provided in order to brake the respective weft thread 1 as required during registration.

Neben dem einfachen mechanischen Aufbau wird die einfache Handhabung und Steuerung als Vorteil angesehen.In addition to the simple mechanical design, the ease of use and control is considered an advantage.
