Description

Die Erfindung betrifft eine Schußsteuereinrichtung für eine Greiferwebmaschine mit einem Schßnwähler, der einen oder mehrere Sätze Zureicher, eine Schußschere und ein Glied zum Trennen des ausgewählten Schußfadens von den übrigen Schußfäden umfaßt, welches Trennglied den ausgewählten Schußfaden über den Greiferkopf des Greifers bringt.The invention relates to a weft control device for a rapier weaving machine with a weft selector, which comprises one or more sets of enrichers, weft scissors and a link for separating the selected weft thread from the other weft threads, which separating element brings the selected weft thread over the rapier head of the rapier.

Aus der US-A-4 022 254 ist eine Schußsteuereinrichtung dieser Art bekannt. Hierbei ist eine stationäre, nockengesteuerte Schußschere vorgesehen, die den Schußfaden abschneidet, nachdem er vom Greifer erfaßt worden ist. Das Trennglied wird von einem nockengesteuerten Schwenkhebel gebildet, welcher lediglich das Loslösen des jeweils ausgewählten Fadens vom Bündel der übrigen Schußfäden erleichtern soll (s. Fig. 3).From US-A-4 022 254 a shot control device of this type is known. Here, a stationary, cam-controlled weft shear is provided which cuts the weft after it has been gripped by the gripper. The separating member is formed by a cam-controlled pivot lever, which is only intended to facilitate the detachment of the respectively selected thread from the bundle of the other weft threads (see FIG. 3).

Die Aufgabe der Erfindung liegt demgegenüber darin, eine Schußsteuereinrichtung vereinfachten Aufbaus und zuverlässiger Funktion bereitzustellen, welche besonders gut an Doppelgreiferwebmaschinen angepaßt werden kann.In contrast, the object of the invention is to provide a weft control device of simplified construction and reliable function, which can be adapted particularly well to double rapier weaving machines.

Diese Aufgabe wird dadurch gelöst, daß die Schußschere mit dem Riet festen verbunden ist und ein Klemmstück, das den ausgewählten Schußfaden erfaßt, sowie ein Schneidemesser zum Schneiden des erfaßten Schußfadens vor dem Ergreifen des Schußfadens durch den Greifer aufweist, und daß das Trennglied von einem linear bewegbaren Schieber gebildet ist, welcher synchron mit dem Riet hin- und herbewegbar ist, um den ausgewählten Schußfaden zwischen dem Klemmstück und dem jeweiligen Zureicher in der Rückzugsstellung des Riets über den Greiferkopf zu bringen.This object is achieved in that the weft scissors are fixedly connected to the reed and have a clamping piece, which grips the selected weft thread, and a cutting knife for cutting the gripped weft thread before gripping the weft thread by the gripper, and in that the separating member is linear from one Movable slide is formed, which can be moved back and forth synchronously with the reed in order to bring the selected weft thread between the clamping piece and the respective enricher in the retracted position of the reed over the hook head.

Aufgrund der festen Verbindung der Schußschere mit dem Riet und der mit dem Riet synchronen Hin- und Herbewegung des linear bewegbaren Schiebers ergibt sich eine besonders einfache, mechanisch robuste Bewegungssteuerung dieser Teile. Die Lage des in der Rückzugsstellung des Riets vom Greiferkopf zu ergreifenden Schußfadenabschnitts ist ziemlich genau dadurch festgelegt, daß das freie Ende dieses Abschnitts im Klemmstück festgelegt ist und das andere Ende dieses Abschnitts in seiner Lage durch den Schieber genau festgelegt wird. Entsprechend hoch ist die Zuverlässigkeit, mit der dieser Abschnitt vom Greiferkopf ergriffen wird. Es können ohne weiteres zwei Schieber übereinander angeordnet werden, so daß die erfindungsgemäße Schußsteuereinrichtung auch für Doppelgreiferwebmaschinen eingesetzt werden kann. Schließlich ergibt sich auch eine schonende Garnbehandlung aufgrund der Verwendung des senkrecht zur FadenLängsrichtung linear bewegbaren Schiebers.Due to the firm connection of the weft scissors to the reed and the back and forth movement of the linearly movable slide synchronous with the reed, this results in a particularly simple, mechanically robust movement control of these parts. The position of the weft section to be gripped in the retracted position of the reed by the rapier head is determined quite precisely by the free end of this section being fixed in the clamping piece and the other end of this section being precisely fixed in position by the slide. The reliability with which this section is gripped by the gripper head is correspondingly high. Two sliders can easily be arranged one above the other, so that the weft control device according to the invention can also be used for double rapier weaving machines. Finally, there is also gentle yarn treatment due to the use of the slider, which can be moved linearly perpendicular to the longitudinal direction of the thread.

Aus der EP-A-7543 ist eine Schußsteuereinrichtung an sich bekannt mit einer Schußschere mit Klemmstück und Schneidemesser, die mit dem Riet solidarisch verbunden ist. In dieser Druckschrift ist jedoch mehrfach hervorgehoben, daß ein Hilfsmechanismus, um den ausgewählten Schußfaden dem Greiferkopf zuzuführen, keinesfalls erforderlich ist.From EP-A-7543 a weft control device is known per se with weft scissors with a clamping piece and cutting knife, which is connected to the reed in solidarity. In this document, however, it is emphasized several times that an auxiliary mechanism for feeding the selected weft thread to the hook head is in no way necessary.

Weitere Besonderheiten der Erfindung werden durch die Beschreibung verdeutlicht, die mit nachstehenden Figuren illustriert ist:

  • Fig. 1 ist eine allgemeine Darstellung der Schußsteuereinrichtung gemäß der Erfindung bei einer Greiferwebmaschine mit einem Fach;
  • Fig. 2 stellt einen Satz Schußzuteiler dar;
  • Fig. 3 die Schußschere;
  • Fig. 4 einen Schieber;
  • Fig. 5 ist eine allgemeine Darstellung der Schußsteuereinrichtung bei einer Doppelgreiferwebmaschine.
Further special features of the invention are illustrated by the description, which is illustrated with the following figures:
  • Fig. 1 is a general illustration of the weft control device according to the invention in a rapier weaving machine with a compartment;
  • Figure 2 illustrates a set of shot allocators;
  • Fig. 3 the weft scissors;
  • 4 shows a slide;
  • Fig. 5 is a general illustration of the weft control device in a double rapier weaving machine.

In Fig. 1 werden lediglich die Bestandteile einer Greiferwebmaschine mit einem Fach dargestellt, die erforderlich sind, um die Erfindung zu beschreiben. In einer derartigen Maschine bilden das Riet 1 mit der obersten Lage Kettfäden 2 und der untersten Lage Kettfäden 3 ein Fach, wodurch der Schußfaden 4 von einem Greifer 5 bis in die Mitte des Fachs mitgenommen wird, wo das mitgenommene Ende des Schußfadens von einem Durchzuggreifer mitgenommen wird, der den Schußfaden durch die zweite Hälfte des Fachs führt. Durch die Anschlagbewegung des Riets 1 wird der Schußfaden gegen das Gewebe 6 gedrückt, das nun einen Schußfaden mehr zählt.In Fig. 1 only the components of a rapier weaving machine with a compartment are shown, which are necessary to describe the invention. In such a machine, the reed 1 with the top layer of warp threads 2 and the bottom layer of warp threads 3 form a compartment, whereby the weft thread 4 is carried by a gripper 5 to the center of the compartment, where the entrained end of the weft thread is carried by a pull-through gripper that passes the weft through the second half of the compartment. The weft thread is pressed against the fabric 6 by the stop movement of the reed 1, which now counts one more weft thread.

Bei Greiferwebmaschinen wird der Schußfaden von einem System stationärer Kreuzspulen 7 angenommen und werden diese mittels stationärer Führungen 8 und 9 zu einem Schußwähler 10 geführt. Tatsächlich werden, um ein Gewebe herzustellen, gewöhnlich Schußfäden verschiedener Arten und/oder Farben verwendet.In rapier weaving machines, the weft thread is accepted by a system of stationary packages 7 and these are guided to a weft selector 10 by means of stationary guides 8 and 9. In fact, different types and / or colors of weft are commonly used to make a fabric.

Durch die Folge der Schußfäden nach Art und Farbe, verbunden mit der Folge der Kettfäden nebeneinander, wird die Gewebezeichnung oder das Motiv bestimmt. Es ist demnach erforderlich, daß der gewünschte Schußfaden, zwischen den verschiedenen vorhandenen, gewählt oder selektiert wird, um von dem Greifer 5 mitgenommen zu werden.The fabric drawing or the motif is determined by the sequence of the weft threads by type and color, combined with the sequence of the warp threads side by side. It is therefore necessary for the desired weft thread to be selected or selected from among the various available ones in order to be taken along by the gripper 5.

Der Schußwähler 10 ist des weiteren mit seinen Besonderheiten in Fig. 2 bildlich dargestellt. Er besteht aus einem stationären Rahmen 11, in dem sich eine Achse 12 befindet, um die ein System Angebehebel 13 in einem bestimmten Winkel frei drehen können.The shot selector 10 is further illustrated with its special features in Fig. 2. It consists of a stationary frame 11 in which there is an axis 12 about which a system indicating lever 13 can freely rotate at a certain angle.

Vorzugsweise befindet sich die Achse 12 des Schußwählers bei der Schußsteuereinrichtung gemäß der Erfindung horizontal und parallel zu der Rietfläche. Jeder Angebehebel 13 (siehe Fig. 2), der mit einem Schußfaden übereinstimmt, hat die Form eines gebogenen oder gefalteten Stabes, der an einem seiner äußeren Enden mit einer Öse 14 ausgerüstet ist, durch die hindurch einer der Schußfäden 4 gezogen wird. Das andere Ende 15 eines jeden Angebehebels 13 ist an dem jeweiligen Zureicher 16 befestigt, der sich frei um die Achse 12 - zwischen zwei Teilen 17 - drehen kann. Der Zureicher 16 ist auch mit einem Arm 18 ausgerüstet, der einen bestimmten Winkel mit dem Arm 19 bildet, in dem der Angebehebel 13 festgesetzt wird.Preferably, the axis 12 of the pick selector in the shot control device according to the invention is horizontal and parallel to the reed surface. Each indicating lever 13 (see Fig. 2) which coincides with a weft thread is in the form of a bent or folded rod which is equipped at one of its outer ends with an eyelet 14 therethrough one of the weft threads 4 is pulled. The other end 15 of each indicating lever 13 is attached to the respective enrichment device 16, which can rotate freely about the axis 12 - between two parts 17. The enricher 16 is also equipped with an arm 18 which forms a certain angle with the arm 19 in which the indicating lever 13 is fixed.

An diesem Arm 18 wird der Zureicher 16 an ein Kabel 20 festgekoppelt, welches zuläßt, daß der Zureicher 16 eine drehende Bewegung um die Achse 12 macht. Jedes Kabel 20 ist dann mit einem Hebel 21 eines frei Programmierbaren Elements 22 des Offenfachtyps verbunden, wie dies zum Beispiel bei einer Jacquard- oder Schaftmaschine der Fall ist.On this arm 18, the enricher 16 is coupled to a cable 20, which allows the enricher 16 to make a rotating movement about the axis 12. Each cable 20 is then connected to a lever 21 of a freely programmable element 22 of the open compartment type, as is the case, for example, with a jacquard or dobby.

Jeder Zureicher (16) des Schußwählers kann zwei Positionen einnehmen: den Ruhestand, wenn der Schußfaden 4 nicht von dem Greifer 5 mitgenommen werden darf und den angegebenen Stand, wenn der Schußfaden 23 ausgewählt wurde, um von dem Greifer 5 mitgenommen zu werden. Die Bewegung wird in der Schußsteuereinrichtung gemäß der Erfindung von dem frei programmierbaren Element 22 aus gesteuert, wobei der Vorteil gegeben ist, daß der ausgewählte Schußfaden 23 in seinem vorgegebenen Stand bleiben kann, solange dies in dem Rapport vorgesehen ist und nicht unnötig bewegt wird - wie dies noch der Fall bei den bekannten Schußsteuereinrichtungen ist - und nicht dem schnellen Rhythmus der Webmaschinengeschwindigkeit unterliegt - mit sämtlichen Risiken, die mit einer schnellen Bewegung verbunden sind, insbesondere dem Reißen und dem Vermischen der Schußfäden.Each selector (16) of the weft selector can assume two positions: the retirement when the weft 4 must not be carried by the hook 5 and the specified position when the weft 23 has been selected to be taken by the hook 5. The movement is controlled in the weft control device according to the invention from the freely programmable element 22, with the advantage that the selected weft thread 23 can remain in its predetermined position as long as this is provided in the repeat and is not moved unnecessarily - as this is still the case with the known weft control devices - and is not subject to the rapid rhythm of the weaving machine speed - with all the risks associated with a rapid movement, in particular the tearing and mixing of the weft threads.

Die Bewegung des ausgewählten Schußfadens 23 aus seiner Ruheposition zu seinem vorgegebenen Stand ist weit genug, um den ausgewählten Faden 23 während der Anschlagbewegung des Webriets in das geöffnete Maul der Schußschere 25 zu bringen; die übrigen Schußfäden 4 werden nicht erfaßt.The movement of the selected weft thread 23 from its rest position to its predetermined position is far enough to bring the selected thread 23 into the open mouth of the weft scissors 25 during the stop movement of the Webriets; the remaining weft threads 4 are not detected.

Während der Anschlagbewegung führt die Schußschere 25, die an dem Schlagrahmen befestigt ist, eine Kippbewegung aus, der eine Schneidebewegung folgt, wobei der Schußfaden von einem Klemmstück 26 (Fig. 3) erfaßt wird und anschließend von einem Schneidemesser geschnitten wird, das aus einem festen Messer 27 und einem beweglichen Messer 25 besteht und mittels Nocken gesteuert wird, wie dies in der EP-A- 7543 beschrieben ist.During the striking movement, the weft scissors 25, which is attached to the striking frame, perform a tilting movement which is followed by a cutting movement, the weft thread being gripped by a clamping piece 26 (FIG. 3) and then cut by a cutting knife which is made from a fixed Knife 27 and a movable knife 25 and is controlled by cams, as described in EP-A-7543.

Während der Rückbewegung des Riets 1 kommt die Schußschere 25 mit dem Riet 1 zurück, um ein Ende des ausgewählten Schußfadens 23 vor den Greifer 5 zu bringen, und zwar entweder von demselben Zureicher 16 aus, der dann in der angegebenen Position geblieben ist oder von einem anderen Zureicher 16 aus, der den vorangehenden ersetzt hat.During the return movement of the reed 1, the weft scissors 25 come back with the reed 1 in order to bring one end of the selected weft thread 23 in front of the gripper 5, either from the same feeder 16, which has then remained in the specified position, or from one other enricher 16 who has replaced the previous one.

Eine andere Kennzeichnung der Schußsteuereinrichtung gemäß der Erfindung ist der Schieber 29 (Fig. 1, Fig. 4), der von einer länglichen Platte mit einem hervorstehenden Stück 30 gebildet wird. Dieser Schieber 29 befindet sich dicht an dem Schußwähler 10 und macht eine horizontale Hin- und Zurückbewegung, und zwar synchron mit dem Riet 1, wie dies von der Rietachse ausgehend gesteuert wird. In dem Augenblick, in dem sich Riet 1 von dem Gewebe 6 zurückbewegt und wiederum ein Fach bildet, bewegt sich der Schieber 28 mit dem hervorstehenden Stück 30 nach vorn und bringt das neue Schußende über den Greiferkopf 31, so daß der neue Schußfaden 23 problemlos von dem Greifer 5 in das Fach gebracht wird.Another identification of the shot control device according to the invention is the slide 29 (Fig. 1, Fig. 4), which is formed by an elongated plate with a protruding piece 30. This slide 29 is located close to the weft selector 10 and makes a horizontal back and forth movement, in synchronism with the reed 1, as is controlled from the reed axis. At the moment when reed 1 moves back from the fabric 6 and again forms a compartment, the slider 28 moves forward with the protruding piece 30 and brings the new weft end over the hook head 31, so that the new weft thread 23 can be easily removed the gripper 5 is brought into the compartment.

Die Schußsteuereinrichtung gemäß der Erfindung ist insbesondere für Doppelgreiferwebmaschinen (Fig. 6) aufgrund ihres vereinfachten Mechanismusses und der Raumbedarfes geeignet.The weft control device according to the invention is particularly suitable for double rapier weaving machines (FIG. 6) due to its simplified mechanism and the space requirement.

Tatsächlich ist es ausreichend, bei dem Schußwähler 10 die Anzahl der Zureicher (13, 13') zu verdoppeln. Es ist sehr einfach, zwei Sätze Zureicher zu verwenden; und zwar den einen über dem anderen, die zusammen von einem frei programmierbaren Element 22 über Fernbedienungskabel 20 gesteuert werden. Auch können sowohl zwei Schieber 29, 29' als auch zwei Schußscheren 25, 25' - die eine über der anderen - montiert werden, die auf dieselbe Weise mit angepaßten Stangen gesteuert werden, wie dies bei der Greiferwebmaschine mit einem Fach der Fall ist.In fact, it is sufficient to double the number of enrichers (13, 13 ') in the shot selector 10. It is very easy to use two sets of enrichers; one above the other, which are controlled together by a freely programmable element 22 via remote control cable 20. Also, two slides 29, 29 'and two weft scissors 25, 25' - one above the other - can be mounted, which are controlled in the same way with adapted rods, as is the case with the rapier weaving machine with a compartment.
