Description

Die Erfindung betrifft einen Zungenöffner für Flachstrickmaschinen, in Form einer Flachbürste, die an einem bewegten Maschinenteil um eine senkrecht zu ihrer Bewegungsrichtung verlaufende Achse verschwenkbar gelagert ist.The invention relates to a tongue opener for flat knitting machines, in the form of a flat brush, which is mounted on a moving machine part so as to be pivotable about an axis running perpendicular to its direction of movement.

Zungenöffner der genannten Art sind aus der DE-C-131 303 bekannt, um in Verbindung mit rohrförmigen Fadenführern neben dem Öffnen der Zungen ein sicheres Offenhalten der Zungen bis zum Einlegen eines Fadens zu ermöglichen. Bei modernen schnellaufenden Flachstrickmaschinen können jedoch frei pendelnd aufgehängte Zungenöffnerbürsten den angestrebten Zweck nicht mehr sicher erfüllen und erfahren einen sehr starken Verschleiß.Tongue openers of the type mentioned are known from DE-C-131 303 in order to enable the tongues to be held open securely until a thread is inserted in addition to opening the tongues in conjunction with tubular thread guides. In modern, high-speed flat knitting machines, freely swinging tongue opener brushes can no longer reliably fulfill the intended purpose and are subject to very heavy wear.

Der Erfindung liegt die Aufgabe zugrunde, Zungenöffner der eingangs genannten Art so auszubilden, daß sie auch bei schnellaufenden Flachstrickmaschinen ihre Funktion sicher erfüllen und der Borstenverschleiß vermindert wird.The invention has for its object to design tongue openers of the type mentioned in such a way that they reliably perform their function even in high-speed flat knitting machines and the bristle wear is reduced.

Die gestellte Aufgabe wird erfindungsgemäß mit den im kennzeichnenden Teil des Hauptanspruchs aufgeführten Merkmalen gelöst. Durch die Zwangsverschwenkung der Bürste werden ihre Borsten rechtzeitig vor dem Auftreffen auf die Nadeln in eine von der Bewegungsrichtung des Schlittens abhängige günstige Schrägstellung zu den Nadelzungen gebracht, so daß sich ein bestimmter, erfahrungsgemäß ermittelter Öffnungswinkel zwischen den Borsten und der Zunge ergibt, der einerseits das Öffnen der Zunge erleichtert und andererseits den bei der Öffnungsarbeit auftretendenen Borstenverschleiß vermindert, so daß sich die Standzeit der Zungenöffnerbürste merklich erhöhen läßt.The object is achieved according to the invention with the features listed in the characterizing part of the main claim. Due to the forced swiveling of the brush, its bristles are brought to the needle tongues in good time before they hit the needles in a favorable inclined position depending on the direction of movement of the slide, so that a certain opening angle, as determined by experience, results between the bristles and the tongue, which on the one hand does that Opening the tongue facilitates and on the other hand reduces the bristle wear that occurs during opening work, so that the service life of the tongue opener brush can be increased significantly.

Die Steuerstange kann vorteilhafterweise mit mehreren Zungenöffnerbürsten zur synchronen Zwangsverschwenkung gekoppelt sein. Dies ist vor allem bei mit mehreren Stricksystemen versehenen Schlitten der Flachstrickmaschinen wichtig, wo die Steuerstange außerdem zweckmäßig als dem Schlitten nachlaufender und vom Schlitten beeinflußbarer Schleppschieber ausgebildet sein kann.The control rod can advantageously be coupled to a plurality of tongue opener brushes for synchronous forced pivoting. This is particularly important in the case of carriages of the flat knitting machines provided with a plurality of knitting systems, where the control rod can also expediently be designed as a sliding slide that follows the carriage and can be influenced by the carriage.

Mit einem erfindungsgemäß ausgebildeten Zungenöffner läß sich gleichzeitig auch das bei Flachstrickmaschinen mit kombinierten Schloßsystemen auftretende Problem, daß Zungenöffner das Umhängen von Maschinen behindern können, durch eine besondere Formgebung der Flachbürsten beseitigen, indem erfindungsgemäß die Länge der Borsten der Flachbürste von einer im unterhalb der Schwenkachse befindlichen Mittelbereich der Bürste auftretenden Maximallänge nach beiden Bürstenenden hin vorzugsweise gleichmäßig abnimmt Durch diese Borstenverkürzung zu den Bürstenenden hin wird erreicht, daß die in Abzugsbewegung befindlichen Nadeln im hinteren Bereich der schräg gestellten Bürsten früher als sonst aus dem Einflußbereich der Bürste heraustreten, so daß die Nadelzungen wieder früh ungehindert schließen können Ein Abheben der Bürsten quer zur Laufrichtung des bewegten Maschinenteiles ist also nicht erforderlich.With a tongue opener designed according to the invention, the problem that can arise in flat knitting machines with combined lock systems that tongue openers can hinder the transfer of machines can also be eliminated by a special shape of the flat brushes, according to the invention the length of the bristles of the flat brush from one located below the pivot axis Middle area of the brush occurring maximum length after both brush ends preferably decreases uniformly This shortening of the bristles towards the brush ends ensures that the needles in the pull-off movement in the rear area of the inclined brushes emerge earlier than usual from the area of influence of the brush, so that the needle tongues again Being able to close early without hindrance It is therefore not necessary to lift the brushes transversely to the running direction of the moving machine part.

Nachfolgend wird ein Ausführungsbeispiel eines erfindungsgemäß ausgebildeten Zungenöffners einzeln und in Kombination mit weiteren Zungenöffnern anhand der beiliegenden Zeichnung näher erläutert.An exemplary embodiment of a tongue opener designed according to the invention is explained in more detail below and in combination with further tongue openers with reference to the accompanying drawing.

Fig. 1 zeigt einen Zungenöffner 10 mit einer Flachbürste mit stegartigem Bürstenkörper 11, in welchem der Borstenbesatz 12 der Flachbürste 11/12 verankert ist. Der Bürstenkörper 11 ist mittels einer Spannpratze 13 und Spannschrauben 14 an einem aus Fig. 2 ersichtlichen abgewinkelten Halter 15 auswechselbar befestigt. Der Halter 15 ist mit einem oberen Lagervorsprung 16 versehen, der um eine durch einen Schraubbolzen 17 gebildete und senkrecht zur Ebene der Flachbürste 11/12 gerichteten Achse in einem gabelförmigen Träger 18 verschwenkbar gelagert ist. Der Träger 18 ist in nicht dargestellter Weise am in Fig. 1 nur angedeuteten Schlittenbacken 19 einer Flachstrickmaschine befestigt.1 shows a tongue opener 10 with a flat brush with a web-like brush body 11, in which the bristle trim 12 of the flat brush 11/12 is anchored. The brush body 11 is fastened interchangeably by means of a clamping claw 13 and clamping screws 14 to an angled holder 15 shown in FIG. 2. The holder 15 is provided with an upper bearing projection 16 which is pivotably mounted in a fork-shaped carrier 18 about an axis formed by a screw bolt 17 and directed perpendicular to the plane of the flat brush 11/12. The carrier 18 is fastened in a manner not shown on the carriage jaws 19 of a flat knitting machine, which are only indicated in FIG. 1.

Fig. 1 zeigt eine Steuerstange 20, die parallel zur Ebene der Flachbürste 11/12 verläuft und mit dem Halter 15 gekoppelt ist. Durch eine Längsverschiebung der Steuerstange in der einen oder anderen Richtung läßt sich der Halter 20 im Träger 18 um die Achse 17 verschwenken und damit 15 auch die Flachbürste 11/12 in eine Schrägstellung bringen.1 shows a control rod 20 which runs parallel to the plane of the flat brush 11/12 and is coupled to the holder 15. By a longitudinal displacement of the control rod in one direction or the other, the holder 20 in the carrier 18 can be pivoted about the axis 17 and thus also 15 bring the flat brush 11/12 into an inclined position.

Bei der aus den Fig. 3 und 4 ersichtlichen Kombination von vier Zungenöffnern 10, die mit ihren Trägern 18 alle am nicht dargestellten Schlittenbacken einer Flachstrickmaschine befestigt sind, ist die Steuerstange als Schleppschieber 20′ ausgebildet, der mit den Haltern 15 aller vier Zungenöffner 10 fest verbunden ist. Der Schleppschieber ist auf seiner Rückseite mit zwei Anschlagrollen 21 versehen, die mit einem am Schlittenbacken begrenzt und durch einen Doppelpfeil 22 angedeutet verschiebbaren Mitnehmer 23 zusammenwirken Durch den Mitnehmer 23 wird der Schleppschieber 20′ in seine Nachlaufstellung verschoben, wodurch die Schrägstellung der Flachbürsten erreicht wird. Fig. 4 zeigt drei der vier Flachbürsten 11/12 in einer Schräglage, die sie bei einer Schlittenbewegung in Richtung des Pfeiles 24 einnehmen. Die Borsten des Borstenteiles 12 der Flachbürsten 11/12 haben in dem unterhalb der Schwenkachse 17 befindlichen Mittelbereich 12.1 eine Maximallänge. In den beidseitig anschließenden Borstenbereichen 12.2 und 12.3 nimmt die Borstenläge zu den Bürstenenden hin gleichmäßig ab. Durch diese Formgestaltung des Borstenbereiches 12 wird erreicht, daß die Nadelköpfe 25 der in Abzugsrichtung bewegten Nadeln sehr früh wieder vom Borstenbereich 12 der Zungenöffner 10 freigegeben werden, wie dies in Fig. 4 an einem der Zungenöffner angedeutet ist. Der Borstenbesatz 12 kann in seinem Randbereich auch noch einen aus Fig. 2 ersichtlichen besonderen Zuschnitt haben, der neben dem bereits eingangs erwähnten, durch die gewählte Schwenkstellung der Flachbürsten 11/12 erreichten Winkel zwischen Nadelzunge und Borsten den sicheren Öffnungsanlauf der Borsten an der Zunge zusätzlich begünstigen und den Borstenverschleiß zusätzlich vermindern hilft.In the apparent from FIGS. 3 and 4 combination of four tongue openers 10, all of which are attached with their supports 18 to the slide jaws of a flat knitting machine, not shown, the control rod is designed as a slide valve 20 ', with the holders 15 of all four tongue opener 10 is firmly connected. The drag valve is provided on its rear side with two stop rollers 21, which cooperate with a slidable driver 23, indicated by a double arrow 22, by means of the driver 23, the drag valve 20 'is moved into its trailing position, whereby the inclined position of the flat brushes is achieved. Fig. 4 shows three of the four flat brushes 11/12 in an inclined position, which they assume during a slide movement in the direction of arrow 24. The bristles of the bristle part 12 of the flat brushes 11/12 have a maximum length in the central region 12.1 located below the pivot axis 17. In the bristle areas 12.2 and 12.3 adjoining on both sides, the bristle length decreases evenly towards the brush ends. This shape of the bristle area 12 ensures that the needle heads 25 of the needles moved in the withdrawal direction are released again very early by the bristle area 12 of the tongue opener 10, as indicated in FIG. 4 on one of the tongue openers. The bristle trim 12 can also have a special cut shown in FIG. 2, which, in addition to the angle between the needle tongue and bristles already mentioned at the beginning, achieved by the selected pivoting position of the flat brushes 11/12, additionally ensures that the bristles open reliably on the tongue favor and additionally reduce the bristle wear.
