Description

Die Erfindung betrifft eine Platine einer Flachstrickmaschine zum Niederhalten von Maschen.The invention relates to a circuit board of a flat knitting machine for Hold down stitches.

Derartige Platinen von Flachstrickmaschinen sind beispielsweise aus der EP 0 238 797 und EP 0 424 717 bekannt. Die Platinen der Flachstrickmaschine nach der EP 0 238 797 B1 sind zugleich Niederhalteelemente und Maschenbilder, während die Platinen der Flachstrickmaschine aus der EP 0 424 717 B1 lediglich eine Niederhaltefunktion ausüben und mit einem starr am Nadelbett angeordneten Maschenbilder zusammenwirken. Den Platinen beider bekannter Flachstrickmaschinen sind jedoch die gleichen Nachteile gemein. Beide Platinen weisen nur eine Niederhaltefläche auf, sodass es nicht möglich ist, Maschen sowohl von einbettigen als auch von doppelbettigen Gestricken sicher niederzuhalten.Such boards of flat knitting machines are made, for example EP 0 238 797 and EP 0 424 717. The boards of the Flat knitting machine according to EP 0 238 797 B1 are at the same time Hold-down elements and mesh images, while the boards of the Flat knitting machine from EP 0 424 717 B1 only one Hold down function and with a rigid on the needle bed arranged mesh images interact. The boards of both However, known flat knitting machines are the same disadvantages common. Both boards have only one hold down, so it is not possible to stitch both embedding and safely hold down double-bed knitted fabrics.

Aus der FR 1 207 319 sind schwenkbar gelagerte Maschenbilder bekannt, die zusätzlich mit einem Maschenrückhaltehaken versehen sind. Die Schwenkbewegung dieser Maschenbilder wird durch translatorisch bewegbare Schieber, die unterhalb des Drehpunkts und unterhalb des Maschenrückhaltehakens angeordnet sind, eingeleitet. Auch bei diesen bekannten Maschenbildern mit Maschenrückhaltefunktion ist keine gleichermaßen sichere Niederhaltefunktion von Maschen einbettiger und doppelbettiger Gestricke gegeben.From FR 1 207 319 are pivotally mounted mesh images known, which additionally provided with a stitch retention hook are. The pivoting movement of these mesh images is through translationally movable slide, which is below the fulcrum and are arranged below the stitch retention hook initiated. Even with these known mesh images with stitch retention function is not an equally safe hold down function given of stitches of single-bed and double-bed knitted fabrics.

Die EP 0 567 282 zeigt schwenkbare Maschenbilder mit Maschenrückhaltehaken für Flachstrickmaschinen mit einem Einzelnadelantrieb. Die Schwenkbewegung der Maschenbilder wird durch translatorisch bewegte Schieber eingeleitet. Diese Schieber sind mit den Nadeln reibschlüssig verbunden, sodass sie ausschließlich gleichsinnige Bewegungen zur Nadel ausführen können. Eine Variation der Maschenrückhaltefunktion in Abhängigkeit von der Art der Gestricke, d. h. von doppelbettigen oder einbettigen Gestricken ist hier ebenfalls nicht gegeben.EP 0 567 282 shows pivotable stitches with stitch retention hooks for flat knitting machines with a single needle drive. The pivoting movement of the mesh images is through translationally moved slides initiated. These sliders are with the needles frictionally connected, so they exclusively can move in the same direction to the needle. A Variation of the stitch retention function depending on the type the knitwear, d. H. of double or single-bed knit is also not here.

Der vorliegenden Erfindung liegt die Aufgabe zu Grunde, die Platine einer Flachstrickmaschine so weiterzubilden, dass das Niederhalten von Maschen einbettiger und doppelbettiger Gestricke in optimaler Weise möglich ist.The present invention is based on the object, the board a flat knitting machine educate so that holding down of mesh single-bed and double-bed knitted fabrics in optimal Way is possible.

Diese Aufgabe wird durch eine Platine gelöst, welche mehrere Maschenniederhalteflächen aufweist. Diese Ausgestaltung gewährleistet es, dass unabhängig davon, ob ein einbettiges oder doppelbettiges Gestrick erzeugt wird, eine der Maschenniederhalteflächen in der Lage ist, die Funktion des sicheren Maschenniederhaltens zu übernehmen. This task is solved by a board, which several Has mesh retaining surfaces. This embodiment ensures it, that regardless of whether a single or double-bed knitted fabric is created, one of the mesh holddown surfaces is able to function the safe To take over stitches.

Bei doppelbettigen Gestricken werden die Maschen von den Niederhalteplatinen des gegenüberliegenden Nadelbetts niedergehalten. Dazu ist in aller Regel eine andere Höhenposition in Bezug auf den Kammspalt erforderlich als beim Niederhalten der Maschen eines einbettigen Gestricks, bei dem die Niederhalteplatinen die Maschen des eigenen Nadelbetts niederhalten. Sind nun mehrere Niederhalteflächen vorgesehen, so eignen sich die Platinen in hervorragender Weise sowohl für einbettige als auch für doppelbettige Gestricke.For double-bed knit the stitches of the Hold down hold-down plates of the opposite needle bed. This is usually another height position in relation on the comb gap required as when holding down the stitches a single-bed knitted fabric, where the hold-down boards the Hold down meshes of your own needle bed. Are now several Holddown surfaces provided so are the boards in excellent way for both single and for double-bed knitwear.

Darüber hinaus können die zusätzlichen Niederhalteflächen auch eine Sicherungsfunktion erfüllen, sofern sich eine Masche doch einmal von der tiefsten Niederhaltefläche lösen sollte. Diese Masche wird dann von einer der nachfolgenden Flächen erfasst. Diese Gefahr des Heruntergleitens von der Niederhaltefläche ist insbesondere bei großen Maschen gegeben, da diese nur mit geringer Spannung an den Niederhalteflächen anliegen.In addition, the additional hold downs can also be a Fulfill a backup function, if a scam but once from should solve the deepest holddown. This mesh will then detected by one of the following surfaces. This danger of Slipping off the hold-down surface is especially at given large meshes, as these are only low voltage abut the holddown surfaces.

Dabei ist es vorteilhaft, wenn die mehreren Maschenniederhalteflächen an verschiedenen, gleich oder unterschiedlich beabstandeten Umfangstellen der Platinen angeordnet sind.It is advantageous if the plurality of mesh retaining surfaces at different, same or different spaced circumferential locations of the boards are arranged.

Die mehreren Maschenniederhalteflächen können bezüglich der Drehachsen der Platinen eine im Wesentlichen radiale Ausrichtung aufweisen. Sie können jedoch auch hakenförmig gestaltet sein. The plurality of mesh holddown surfaces may relate to the Rotary axes of the boards a substantially radial orientation exhibit. However, they can also be designed hook-shaped.

Die Drehachse der Platine kann vorzugsweise oberhalb der Nadelschäfte angeordnet sein. Auch durch diese Maßnahme lässt sich die Niederhaltewirkung der Platine verbessern, da die Maschenniederhalteflächen bei relativ weit oben am Nadelbett angeordneten Drehachsen die Maschenschenkel in der unteren Schwenkstellung besser einschließen.The axis of rotation of the board can preferably above the Needle shafts can be arranged. Also by this measure can be improve the hold down effect of the board, as the Maschenniederhalteflächen at relatively high on the needle bed arranged rotary axes, the mesh legs in the lower Include pivot position better.

In einer weiteren Ausgestaltung können die Platinen mehrere Maschenniederhalteflächen und mindestens eine Maschenbilderfläche aufweisen. Sie vereinen damit sowohl die Niederhalte- als auch die Maschenbildungsfunktion in sich. Bei einer anderen Variante können die Platinen lediglich mehrere Maschenniederhalteflächen aufweisen und mit starr an den Nadelbetten angeordneten Maschenbildern zusammenwirken.In a further embodiment, the boards can more Mesh holddown surfaces and at least one mesh canvas exhibit. They combine both the hold-down and the Meshing function in itself. In another variant can the boards only have multiple mesh holddown surfaces and with stitches rigidly attached to the needle beds interact.

Nachfolgend werden zwei bevorzugte erfindungsgemäße Platinen als verwendende Ausführungsbeispiele von Flachstrickmaschinen anhand der Zeichnung näher beschrieben. Es zeigt:

Die Schnittdarstellung in Fig. 1 zeigt eine Vorrichtung 100 einer Flachstrickmaschine zum Niederhalten und Bilden von Maschen. Von der Flachstrickmaschine ist ein Nadelbett 4 gezeigt, in dem Nadeln 7 längs verschieblich in Nuten 41 geführt sind. Der Nutgrund ist mit 42 gekennzeichnet. An der vorderen Stirnseite weist das Nadelbett 4 Nuten 43 zur Aufnahme von Platinenführungsstücken 3 auf, an denen Platinen 1 schwenkbar geführt sind. Die Platinenführungsstücke 3 weisen hierzu eine kreisförmige Aussparung 31 auf, in die ein Kreissegment 14 der Platine 1 eingreift. Auf diese Weise ist die Platine 1 um die Drehachse 18 in Pfeilrichtung D und in Gegenpfeilrichtung D' begrenzt verschwenkbar. Die Begrenzung der Schwenkbewegung erfolgt dabei ebenfalls durch das Platinenführungsstück 3. Die Anschlagfläche 33 des Platinenführungsstücks 3 begrenzt die Öffnungsbewegung der Platine 1 in Pfeilrichtung D und die Fläche 34 die Bewegung nach unten in Pfeilrichtung D'. Die Verbindung der Platinenführungsstücke 3 mit dem Nadelbett erfolgt über einen Draht 44, der über die gesamte Länge durch das Nadelbett hindurch verläuft. Der Abschlagdraht 45 für die Maschen ist durch Langlöcher 19 in sämtlichen Platinen 1 hindurchgeführt. The sectional view in Fig. 1 shows an apparatus 100 of a flat knitting machine for holding down and forming stitches. From the flat knitting machine, a needle bed 4 is shown in the needles 7 are guided longitudinally displaceable in grooves 41 . The groove bottom is marked 42 . At the front end, the needle bed 4 grooves 43 for receiving board guide pieces 3 on which boards 1 are pivotally guided. The board guide pieces 3 have for this purpose a circular recess 31 into which a circular segment 14 of the board 1 engages. In this way, the circuit board 1 about the rotational axis 18 in the direction of arrow D and in the opposite direction D ' pivotally limited. The stop surface 33 of the sinker guide piece 3 limits the opening movement of the board 1 in the direction of arrow D and the surface 34, the movement down in the direction of arrow D '. The connection of the board guide pieces 3 with the needle bed via a wire 44 which extends over the entire length through the needle bed. The stitching wire 45 for the stitches is passed through slots 19 in all boards 1.

Die Platine 1 weist eine Funktionsfläche 11 zum Bilden von Maschen, eine Wirkfläche 12 zum Niederhalten von Maschen von einbettigen Gestricken und weitere Wirkflächen 13, 13.1, 13.2 zum Niederhalten von Maschen des gegenüberliegenden Nadelbetts bei doppelbettigen Gestricken bei Flachstrickmaschinen mit zwei Nadelbetten auf. Die Schwenkbewegung der Platine 1 in Pfeilrichtung D bzw. D' wird durch ein Federelement 2 ausgelöst. Dieses Federelement 2 ist in einem oberhalb des Nadelbetts 4 angeordneten Schieberbett 6 geführt. Dazu weist auch das Schieberbett 6 Längsnuten 61 auf, in die die Federelemente 2 eingesetzt sind. Das Federelement 2 weist einen U-förmigen Biegefederabschnitt mit Schenkeln 22, 24 auf. Der freie Schenkel 24 ist im Abschnitt 25 nach außen umgebogen. Mit diesem Abschnitt 25 greift das Federelement 2 an der Platine 1 an. In der in Fig. 1 dargestellten vollständigen Öffnungsstellung der Platine 1 setzt der Abschnitt 25 dabei an der Fläche 16 der Platine 1 an. Bei einer Schwenkbewegung der Platine 1 in Richtung D' wird dagegen die Fläche 17 der Platine 1 vom Federelementabschnitt 25 beaufschlagt. Dies geschieht durch ein Verschieben des Federelements 2 in der Nut 61, wie nachfolgend auch noch in den Fig. 2 und 3 illustriert ist. Die Verschiebung wird dabei von Schlossteilen des Schlittens der Flachstrickmaschine ausgelöst, die an einem Fuß 21 des Federelements 2 angreifen. Das Schieberbett 6 ist über eine Verbindungsleiste 5 mit dem Nadelbett 4 verbunden. Die Verbindungsleiste 5 weist dazu zwei schwalbenschwanzförmige Abschnitte 51, 52 auf, die in entsprechend geformte Nuten am Nadelbett 4 bzw. dem Schieberbett 6 eingreifen. Die Verschiebebewegung des Federelements 2 wird über einen Draht 63, der in einem Langloch 23 des Federelements 2 hindurchgeführt ist, begrenzt. Über den Abschnitt 25 wird eine Verschiebebewegung des Federelements 2 in eine Rotationsbewegung der Platine 1 übersetzt. Um dabei die erforderlichen Verschiebebewegungen der Federelemente 2 zur Auslösung der erforderlichen Schwenkbewegung der Platine 1 minimal zu halten, greift der Abschnitt 25 des Federelements 2 in einem Abstand zur Drehachse 18 der Platine an, der geringer ist als der Abstand der Niederhaltefläche 12 zur Drehachse 18.The circuit board 1 has a functional surface 11 for forming stitches, an active surface 12 for holding down loops of single-bed knitted fabrics and further active surfaces 13 , 13.1 , 13.2 for holding down loops of the opposing needle bed in double-bed knit fabrics in flat knitting machines with two needle beds. The pivoting movement of the board 1 in the direction of arrow D or D 'is triggered by a spring element 2 . This spring element 2 is guided in a cylinder disposed above the needle bed 4 slider bed. 6 For this purpose, the slide bed 6 has longitudinal grooves 61 into which the spring elements 2 are inserted. The spring element 2 has a U-shaped spiral spring section with legs 22, 24 . The free leg 24 is bent in the section 25 to the outside. With this section 25, the spring element 2 engages the circuit board 1. In the illustrated in Fig. 1 complete open position of the board 1, the section 25 is doing on the surface 16 of the board 1 at. In a pivoting movement of the board 1 in the direction D ', however, the surface 17 of the board 1 is acted upon by the spring element section 25. This is done by a displacement of the spring element 2 in the groove 61 , as also illustrated below in Figs. 2 and 3. The displacement is triggered by lock parts of the carriage of the flat knitting machine, which engage a foot 21 of the spring element 2. The slide bed 6 is connected via a connecting bar 5 with the needle bed 4. For this purpose, the connecting strip 5 has two dovetail-shaped sections 51, 52 which engage in correspondingly shaped grooves on the needle bed 4 and the slide bed 6, respectively. The displacement movement of the spring element 2 is limited by a wire 63 , which is guided in a slot 23 of the spring element 2. Via the section 25, a displacement movement of the spring element 2 is translated into a rotational movement of the board 1. In order to keep the required displacement movements of the spring elements 2 to trigger the required pivotal movement of the board 1 minimal, the portion 25 of the spring element 2 engages at a distance from the axis of rotation 18 of the board, which is less than the distance of the hold-down surface 12 to the axis of rotation 18th

Fig. 2 zeigt im Gegensatz zur Fig. 1, in der die Platine 1 in ihrer Außertätigkeitsstellung gezeigt ist, die Platine 1 in ihrer vollständigen Schließstellung, in der sie mit der Fläche 12 einen Maschenschenkel 9 der Nadel 7 zurückhält. Die Platine 1 ist dazu in Drehrichtung D' so weit vorgeschwenkt worden, bis ihre Fläche 16 an einer Anschlagsfläche 34 des Platinenführungsstücks 3 anliegt. Das Federelement ist zur Auslösung dieser Drehbewegung der Platine 1 im Pfeilrichtung X maximal nach vorne verschoben worden. Der Abschnitt 25 des Federelements 2 greift jetzt an der Fläche 17 an. Die Platine 1 kann sich jedoch in Pfeilrichtung D entgegen der Federkraft des Federelements 2 begrenzt nach oben bewegen. In Fig. 2 ist jedoch die Stellung der Platine 1 für große Maschen 9 gezeigt, die die Platine 1 nicht entgegen der Federkraft nach oben ziehen. Sollte sich die Masche 9 von der Fläche 12 lösen, könnte sie durch eine der Flächen 13 bis 13.2 wieder eingefangen werden. Fig. 2 shows, in contrast to FIG. 1, in which the circuit board 1 is shown in its off-mode, the board 1 in its fully closed position in which it retains a mesh leg 9 of the needle 7 with the surface 12. The board 1 has been so far swiveled in the direction of rotation D 'until its surface 16 rests against a stop surface 34 of the blanking guide piece 3. The spring element has been moved to trigger this rotational movement of the board 1 in the direction of arrow X maximum forward. The section 25 of the spring element 2 now engages the surface 17. However, the board 1 can move in the direction of arrow D against the spring force of the spring element 2 limited move upwards. In Fig. 2, however, the position of the board 1 is shown for large meshes 9, which does not pull the board 1 against the spring force upwards. Should the stitch 9 detach from the surface 12, it could be recaptured by one of the surfaces 13 to 13.2.

Fig. 3 hingegen zeigt die Anordnung gemäß Fig. 2 beim Niederhalten von kleinen Maschen 9. Die Platine 1 ist jetzt entgegen der Pfeilrichtung D' und entgegen der Kraft der Feder 2 nach oben verschwenkt worden. Die Schwenkbewegung wird dabei vom Federelement 2 selbst begrenzt. Der freie Schenkel 24 des U-förmigen Biegefederabschnitts liegt jetzt am Schenkel 22 an. Ein weiteres Nachobendrücken der Platine 1 durch die Masche 9 ist daher ausgeschlossen. Auch hier erfüllen die zusätzlichen Flächen 13 bis 13.2 eine Sicherungsfunktion. Fig. 3, however, shows the arrangement of FIG. 2 while holding down small stitches 9. The board 1 has now been pivoted against the direction of the arrow D 'and against the force of the spring 2 upwards. The pivoting movement is limited by the spring element 2 itself. The free leg 24 of the U-shaped spiral spring portion is now on the leg 22 at. Another Nachobendrücken the board 1 through the mesh 9 is therefore excluded. Again, the additional surfaces 13 to 13.2 fulfill a backup function.

Das Federelement 2 ist in den Nuten 61 des Schieberbetts 6 mit Reibung geführt. Dies führt dazu, dass es in jeder Schieberposition seine Lage beibehält, wenn die Schlossteile es nicht mehr beaufschlagen. Dadurch können sämtliche Federelemente 2 und damit auch die Platinen 1 in einer definierten Schwenkposition gehalten werden.The spring element 2 is in the grooves 61 of the valve bed 6 with Friction led. This causes it in every slider position retains its position when the lock parts stop it apply. This allows all the spring elements 2 and so that the boards 1 in a defined pivot position being held.

Fig. 4 zeigt im Querschnitt eine Vorrichtung 200 zum Niederhalten von Maschen einer Flachstrickmaschine mit zwei Nadelbetten 4, 4'. Jedes der Nadelbetten ist im dargestellten Beispiel mit Platinen 1, 1', Federelementen 2, 2' und Stricknadeln 7, 7', wie sie in Fig. 1 gezeigt sind, ausgerüstet. Das bedeutet, dass die Vorrichtung 101 zum Niederhalten von Maschen des zweiten Nadelbetts 4' identisch ist zur Vorrichtung 100 des Nadelbetts 4. Bei Gestricken, deren Maschen auf beiden Nadelbetten 4, 4' gebildet werden, d. h. so genannten doppelbettigen Gestricken, ist die Wirkung der Niederhaltefläche 12, 12' eingeschränkt. Zum sicheren Niederhalten der Maschen bei doppelbettigen Gestricken weist deswegen die Platine 1 des vorderen Nadelbetts 4 zusätzliche Funktionsflächen 13, 13.1, 13.2 und die Platine 1' des hinteren Nadelbetts 4' zusätzliche Funktionsflächen 13', 13.1', 13.2' auf. Diese Funktionsflächen erfassen die Maschenschenkel 9' der Maschen, die sich auf dem Schaft der ihnen gegenüberliegenden Nadeln 7, 7' befinden und halten diese zurück, wenn die Nadeln 7, 7' ihre Vortriebsbewegung ausführen. Im Beispiel gemäß Fig. 4 hat die Funktionsfläche 13 der Platine 1 des vorderen Nadelbetts 4 den Maschenschenkel 9' der Nadel 7' des hinteren Nadelbetts 4' erfasst. 4 shows in cross section a device 200 for holding down loops of a flat knitting machine with two needle beds 4, 4 '. Each of the needle beds is in the illustrated example with boards 1, 1 ', spring elements 2, 2' and knitting needles 7, 7 ', as shown in Fig. 1, equipped. This means that the device 101 for holding down stitches of the second needle bed 4 'is identical to the device 100 of the needle bed 4. For knitted fabrics whose stitches are formed on both needle beds 4, 4', ie so-called double-bed knitted fabrics, the effect of Hold-down surface 12, 12 ' limited. For safe hold down of the stitches in double-bed knitted fabrics, therefore, the board 1 of the front needle bed 4 additional functional surfaces 13, 13.1, 13.2 and the board 1 'of the rear needle bed 4' additional functional surfaces 13 ', 13.1', 13.2 ' on. These functional surfaces grasp the mesh legs 9 'of the stitches which are located on the shaft of the needles 7, 7' lying opposite them and hold them back when the needles 7, 7 ' carry out their advancing movement. In the example according to FIG. 4, the functional surface 13 of the board 1 of the front needle bed 4 has grasped the loop leg 9 'of the needle 7' of the rear needle bed 4 '.
