Description

Die Erfindung bezieht sich auf eine Drehereinrichtung für Webmaschinen, insbesondere für Doppelgreiferwebmaschinen für Doppelsamt oder Teppiche, um riffelfeste Kanten zu erhalten.The invention relates to a lathe device for weaving machines, in particular for double rapier weaving machines for double velvet or carpets, in order to obtain corrugated edges.

Drehereinrichtungen werden bei Geweben gebraucht, um einen Teil der Kettfäden, die sogenannten Dreherfäden, einmal rechts und einmal links von den Stehfäden zu positionieren. Dies hat zur Folge, daß die Dreherfäden um die Stehfäden gedreht oder gewunden werden.Twisting devices are used in fabrics to position part of the warp threads, the so-called leno threads, once on the right and once on the left of the standing threads. As a result, the leno threads are twisted or wound around the standing threads.

Die Vorrichtungen zur Durchführung dieses Vorgangs sind ziemlich kompliziert, und es wurden schon verschiedene Versuche unternommen, um sie zu vereinfachen.The devices for performing this operation are quite complex and various attempts have been made to simplify them.

Unter anderem wird in dem DE-GM 80 05 822 eine Lösung beschrieben, bei der einerseits Stehfäden durch Nadeln positioniert werden und andererseits Dreherfäden durch kombinierte Bewegung von mit Augen versehenen Hebeln und einer mit schrägen Schlitzen versehenen, die Dreherfäden bildenden Führungsplatte positioniert werden. Diese Drehereinrichtung hat drei Fachbildungselemente mit den zugehörigen Webrahmen nötig, nämlich einen Webrahmen mit der Bewegung 1/1 für die Nadelstange (Stehfadenrost), einen Webrahmen mit der Bewegung 1/1 für das Gestänge der Fadenaugen und einen Webrahmen mit der Bewegung -2/2 für die Dreherfadenpositioniervorrichtung.Among other things, DE-GM 80 05 822 describes a solution in which standing threads are positioned by needles on the one hand, and leno threads are positioned on the other by combined movement of levers provided with eyes and a guide plate provided with oblique slots that form the leno threads. This lathe device requires three shed forming elements with the associated weaving frames, namely a weaving frame with movement 1/1 for the needle bar (standing thread grid), a weaving frame with movement 1/1 for the linkage of the thread eyes and a weaving frame with movement -2/2 for the leno thread positioning device.

Dies ist natürlich auch kein einfacher Antrieb, der drei Elemente von der bestehenden Webfachvorrichtung benötigt, wie Schaftmaschine oder Nockenscheibenmaschine. Darüberhinaus ist eine unabhängige winkelsynchrone Einstellung - links und rechts separat - in bezug auf die Hauptwelle nicht möglich.Of course, this is also not a simple drive that requires three elements from the existing shed device, such as a dobby or cam machine. It is also an independent angle synchronous adjustment - left and right separately - not possible with regard to the main shaft.

Die Aufgabe der Erfindung ist es, eine Drehereinrichtung zu verwirklichen, bei der der Antrieb unabhängig von der Schaftmaschine ist, die keine zusätzlichen Webrahmen benötigt und bei der die winkelsynchrone Einstellung in bezug auf die Hauptwelle möglich ist. Die Drehereinrichtung für eine Webmaschine gemäß der Erfindung ist gekennzeichnet durch vierstangige Parallelogramme mit senkrecht stehenden Vorderseiten, an denen jeweils die Nadeln, die Fadenaugenhalter bzw. die Fadenpositionieraugen befestigt sind, während die Rückseite die Gelenke tragen, um die sich die anderen Stangen der Parallelogramme hin- und herbewegen, so daß sowohl die Nadeln als auch die Fadenaugenhalter und die Positionieraugen eine vertikale Bewegung ausführen und lediglich einen sehr kleinen Bogen beschreiben.The object of the invention is to realize a lathe device in which the drive is independent of the dobby, which does not require additional looms, and in which the angle-synchronous adjustment with respect to the main shaft is possible. The lathe device for a weaving machine according to the invention is characterized by four-bar parallelograms with vertically standing front sides, to each of which the needles, the thread eye holders or the thread positioning eyes are fastened, while the rear side carries the joints around which the other bars of the parallelograms extend. and move so that the needles as well as the thread eye holders and the positioning eyes make a vertical movement and only describe a very small arc.

Das die Parallelogramme bildende Gestänge kann modular nebeneinander gebaut werden, wobei die Gelenke rahmenfest verbunden und in der Breite einstellbar sind.The linkage forming the parallelograms can be built modularly next to one another, the joints being connected to the frame and adjustable in width.

Weitere Merkmale und Vorteile einer Drehereinrichtung für Webmaschinen gemäß der Erfindung ergeben sich aus der Beschreibung einer Drehereinrichtung für eine Webmaschine, so wie in der Zeichnung dargestellt, wobei die Zeichnung eine perspektivische Ansicht einer solchen Drehereinrichtung darstellt.Further features and advantages of a lathe device for looms according to the invention result from the description of a lathe device for a loom, as shown in the drawing, the drawing showing a perspective view of such a lathe device.

Bei einer Drehereinrichtung einer Webmaschine, so wie in der Figur dargestellt, werden die Kettfäden in Stehfäden 1 und 2 ... und in Dreherfäden 3, 4, 5, 6 ... aufgeteilt.In a leno device of a weaving machine, as shown in the figure, the warp threads are in standing threads 1 and 2 ... and in leno threads 3, 4, 5, 6 ... divided.

Die Drehereinrichtung gemäß der Erfindung besteht aus verschiedenen, von Stangen gebildeten Parallelogrammen. Das Stangenparallelogramm der Stehfäden 1 und 2 ... trägt an beiden Enden seiner vertikalen Vorderseitenstange 7 jeweils einen Nadelhalter 8 und einen Nadelhalter 9, worin jeweils die oberen Nadeln 10 und die unteren Nadeln 11 vertikal einstellbar sind. Die Nadelhalter 8 und 9 sind mit einer Positioniervorrichtung 12 und 13 ... versehen, durch die die entsprechenden Stehfäden 1, ... und 2,... geführt werden, um dann längs der Nadeln 10 und 11 und den Nadelöhren 14 und 15 weiter zum Webblatt (nicht dargestellt) der Webmaschine geleitet zu werden. Die senkrechte Vorderseitenstange 7 des den Stehfäden zugeordneten Parallelogramms ist mit Gelenken 16 und 17 sowie deren Achsen 18 und 19 versehen. Um diese Achsen 18 und 19 können sich die Stangen 20 und 21 des entsprechenden Parallelogramms hin- und herdrehen. Die hintere vertikale Seite wird durch eine Stange 22 mit einer oberen Achse 23 und einer unteren Achse 24 gebildet, um die sich die entsprechende obere zugehörige Stange 20 und die entsprechende untere anliegende Stange 21 hin- und herdrehen können. Dies hat zur Folge, daß die Vorderseitenstange 7 der Stehfäden auf und nieder bewegt werden kann, wobei die Nadeln in einer vertikalen Lage gehalten werden können.The lathe device according to the invention consists of various parallelograms formed by rods. The rod parallelogram of the standing threads 1 and 2 ... carries a needle holder 8 and a needle holder 9 at both ends of its vertical front side rod 7, wherein the upper needles 10 and the lower needles 11 are vertically adjustable. The needle holders 8 and 9 are provided with a positioning device 12 and 13 ..., through which the corresponding standing threads 1, ... and 2, ... are guided, in order to then along the needles 10 and 11 and the needle tubes 14 and 15th to be directed to the weaving reed (not shown) of the weaving machine. The vertical front side rod 7 of the parallelogram assigned to the standing threads is provided with joints 16 and 17 and their axes 18 and 19. The rods 20 and 21 of the corresponding parallelogram can rotate back and forth about these axes 18 and 19. The rear vertical side is formed by a rod 22 having an upper axis 23 and a lower axis 24 about which the corresponding upper associated rod 20 and the corresponding lower adjacent rod 21 can rotate back and forth. This has the consequence that the front side bar 7 of the standing threads can be moved up and down, whereby the needles can be held in a vertical position.

In gleicher Art und Weise werden die Dreherfäden 3, 4, ... und 5, 6, ... durch die entsprechenden Positionieraugen 25, ... und 26, ... geführt. Die Halter 27 und 28 der Positionieraugen 25, ... und 26, ... sind an der vertikalen Stange '23 befestigt, die gleichzeitig die vertikale Vorderseite des den Positionieraugen 25, ... und 26, ... zugeordneten Parallelogramms ist. Diese Vorderseite hat zwei Gelenke 30 und 31 für die Stangen 32 und 33, die sich auch um die Achsen 23 und 24 hin- und herdrehen können, während die Stange 22 die Rückseite des den Positionieraugen 25, ... 26, ... zugeordneten Parallelogramms darstellt.In the same way, the leno threads 3, 4, ... and 5, 6, ... are guided through the corresponding positioning eyes 25, ... and 26, .... The holders 27 and 28 of Positionieraugen 25, ... and 26, ... are attached to the vertical rod '23 secured, which is simultaneously the vertical front of the parallelogram assigned to the positioning eyes 25, ... and 26, .... This front side has two joints 30 and 31 for the rods 32 and 33, which can also rotate back and forth about the axes 23 and 24, while the rod 22 the back of the positioning eyes 25, ... 26, ... assigned Represents parallelogram.

Genauso gehen weiterhin die Dreherfäden 3, 4, ... und 5, 6, ... durch die zugeordneten Schlitze 34, ... und 35, ..., deren Halter 36 und 37 an den äußeren Enden der vertikalen Stange 38 befestigt sind. Diese Stange 38 ist die Vorderseite des den Schlitzhaltern 36 und 37 zugeordneten Parallelogramms, das weiterhin aus den Stangen 38 und 39 und der als Rückseite dienenden vertikalen Stange 22 besteht.Likewise, the leno threads 3, 4, ... and 5, 6, ... continue through the associated slots 34, ... and 35, ..., the holders 36 and 37 attached to the outer ends of the vertical rod 38 are. This rod 38 is the front of the parallelogram associated with the slot holders 36 and 37, which further consists of the rods 38 and 39 and the vertical rod 22 serving as the rear.

Die Parallelogrammgestänge sind modular nebeneinander auf rahmenfest verbundenen Gelenken angeordnet und sind in der Breite auf die zu webende Gewebebreite einstellbar. Die Lage der Nadeln, Schlitze und Augen kann mit Hilfe von Stellschrauben an den vertikalen Zugstangen eingestellt werden.The parallelogram linkages are arranged modularly next to each other on hinges connected to the frame and the width can be adjusted to the fabric width to be woven. The position of the needles, slits and eyes can be adjusted with the help of set screws on the vertical pull rods.

Die unteren Parallelogrammstangen 21, 33 und 38 haben jede ein Verlängerungsstück 40, das an seinem Ende ein Gelenk 41, ... trägt und durch Hebel 42 und 43, ... jeweils mit.einem Druckrad 44, ... verbunden ist, so daß durch Kurvenscheiben 45 bei Drehung der Kurvenscheibenwelle 46 und durch die Zugfedern 47 eine auf- und niedergehende Bewegung der vertikalen Vorderseitenstangen, des entsprechenden Nadelparallelogramms, des Schlitzhalterparallelogramms und des Positionieraugenparallelogramms verursacht wird.The lower parallelogram rods 21, 33 and 38 each have an extension piece 40, which carries a joint 41, ... at its end and is connected to a pressure wheel 44, ... by levers 42 and 43, ..., respectively that by means of cams 45 when the cam shaft 46 rotates and by the tension springs 47 an up and down movement of the vertical front bars, the corresponding needle parallelogram, the slot holder parallelogram and the positioning eye parallelo gramms is caused.

Die winkelsynchrone Einstellung wird durch Drehen der Kurvenscheiben 45 auf der Kurvenscheibenwelle 46 erreicht. Diese Welle dreht in bezug auf die Hauptwelle im Verhältnis 1/4, so daß die Nadeln 10, und 11, ... eine Bewegung von 1/1, die Schlitze 34, ... 35, ... von 1/1 im Gegentakt und die Fadenpositionieraugen 25, ... und 26, ... eine Bewegung von 2/2 ausführen.The angularly synchronous setting is achieved by rotating the cam disks 45 on the cam disk shaft 46. This shaft rotates 1/4 in relation to the main shaft, so that the needles 10 and 11, ... a movement of 1/1, the slots 34, ... 35, ... of 1/1 in Push-pull and the thread positioning eyes 25, ... and 26, ... perform a movement of 2/2.
