Description

Die Erfindung betrifft ein Verfahren zur Herstellung eines Gestricks auf einer Flachstrickmaschine mit mindestens einem Nadelbett mit mehreren, längsverschiebbar geführten Nadeln, zwischen denen in Nadellängsrichtung verschiebbare Platinen angeordnet sind.The invention relates to a method for producing a knitted fabric on a flat knitting machine with at least one Needle bed with several needles that can be moved lengthways, between which boards can be moved in the longitudinal direction of the needle are arranged.

Aus der DE 32 47 767 A1 ist bereits eine Strickmaschine mit parallel zur Nadelbewegungsebene verschiebbaren Maschenbildungsplatinen bekannt, wobei die Maschenbildungsplatinen in der ersten Phase der Austriebsbewegung der Stricknadeln in derselben Richtung, aber mit geringerer Geschwindigkeit bewegt werden, um dadurch die Geschwindigkeit der Nadelzungen bei ihrem öffnungsvorgang zu vermindern.DE 32 47 767 A1 already includes a knitting machine Stitching boards that can be moved parallel to the plane of needle movement known, the stitch formation boards in the first phase of the expulsion movement of the knitting needles in moving in the same direction but at a slower speed to reduce the speed of the needle tongues lessen their opening process.

Die EP-A-0 672 769 beschreibt ebenfalls eine Flachstrickmaschine mit in Nädellängsrichtung steuerbar verschieblichen Platinen gemäß dem Oberbegriff von Anspruch 4.EP-A-0 672 769 also describes a flat knitting machine with slidably controllable in the longitudinal direction of the needle Boards according to the preamble of claim 4.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, bei der Maschenbildung auf einer Flachstrickmaschine mit Hilfe von Platinen zu verhindern, dass beim Nadelvortrieb der Strickfaden aus dem Nadelhaken springt, auch wenn der Strickfaden eine hohe Eigensteifigkeit aufweist, aus mehreren Fäden gebildet ist oder wenn mehrere Fanghenkel in den Nadelhaken eingelegt werden müssen. The present invention is based on the object Stitching on a flat knitting machine with the help of Sinkers prevent the knitting thread from advancing the needle jumps out of the needle hook, even if the knitting thread is a has high inherent rigidity, formed from several threads or if several tuck handles are inserted in the needle hook Need to become.

Die Aufgabe wird mit einem Verfahren zur Herstellung eines Gestricks auf einer Flachstrickmaschine mit mindestens einem Nadelbett mit mehreren längsverschiebbar geführten Nadeln, zwischen denen in Nadellängsrichtung verschiebbare Platinen angeordnet sind, gelöst, wobei das Verfahren gekennzeichnet ist durch die Schritte:

  • zur Bildung einer neuen Masche Einziehen der Nadel mit dem im Nadelhaken liegenden Strickfaden in das Nadelbett, wobei sich die Maschenschleife an der Wirkfläche an der Brustseite der neben der Nadel liegenden Platine abstützt,
  • anschließend Austreiben der Nadel, während die Platine mindestens während des Beginns der Austriebsbewegung der Nadel ebenfalls und mit gleicher Geschwindigkeit wie die Nadel ausgetrieben wird, wodurch die Wirkfläche der Platine die Maschenschenkel gespannt hält,
  • sobald die Maschenschleife durch eine Gestrickabzugseinrichtung, Einstreifeinrichtungen, Niederhalteplatinen o. dgl. sicher in der Nadel gehalten wird, weiterer Austrieb der Nadel bis zur Kammgleiche, während die Platine wieder in ihre Ausgangsstellung eingezogen wird.
The object is achieved with a method for producing a knitted fabric on a flat knitting machine with at least one needle bed with a plurality of needles which can be displaced longitudinally and between which plates which are displaceable in the longitudinal direction of the needle are arranged, the method being characterized by the steps:
  • to form a new stitch, pulling the needle with the knitting thread in the needle hook into the needle bed, the stitch loop being supported on the active surface on the chest side of the board lying next to the needle,
  • then driving out the needle while the board is being driven out at least at the same time as the needle at least during the start of the pushing-out movement of the needle, as a result of which the active surface of the board keeps the stitch legs taut,
  • as soon as the stitch loop is held securely in the needle by means of a knitting device, stripping devices, hold-down plates or the like, the needle is driven out further until the ridge is equal, while the board is drawn back into its starting position.

Mit Hilfe des erfindungsgemäßen Verfahrens wird somit erreicht, dass während der kritischen Phase des Maschenbildungsvorgangs die Maschenschenkel stets gespannt gehalten werden, sodass es nicht zu einem Herausspringen des Strickfadens aus dem Nadelhaken kommen kann. Die Platinen sind einzeln ansteuerbar, sodass bei Bedarf nur die Platinen derjenigen Nadeln, die einen entsprechend eigensteifen Strickfaden bzw. mehrere Strickfäden gleichzeitig verarbeiten, aktiviert werden müssen. Mit Hilfe der Platinen lassen sich jedoch noch weitere Vorteile erreichen. So können zur Erzeugung mindestens einer vergrößerten Masche vor dem Einziehen des Strickfadens zur Bildung dieser Masche durch Einziehen der Nadel in das Nadelbett die beiden der Nadel benachbarten Platinen entsprechend der gewünschten Maschenvergrößerung ausgetrieben werden und die Nadel nur bis zu einer Standard-Einzugstiefe für alle Nadeln des Nadelbettes eingezogen werden. Hier wird also die Maschengröße nicht mehr allein durch eine entsprechende Kuliertiefe der Nadel beeinflusst, sondern durch Einnahme einer zusätzlichen Austriebsposition durch die Platinen.With the aid of the method according to the invention, that during the critical phase of the stitch formation process the mesh legs are always kept taut, so that the knitting thread does not pop out the needle hook can come. The boards can be controlled individually, so that if necessary only the boards of those Needles that have a correspondingly stiff knitting thread or Process multiple knitting threads simultaneously, be activated have to. With the help of the boards, however, more can be done Achieve advantages. So you can generate at least one enlarged stitch before pulling in the knitting thread Form this stitch by pulling the needle into the needle bed the two boards adjacent to the needle accordingly the desired stitch enlargement are driven out and the needle only up to a standard feed depth for everyone Needles of the needle bed are retracted. So here is the Mesh size no longer solely through a corresponding depth the needle, but by taking one additional expulsion position through the boards.

Bei einer weiteren bevorzugten Ausführungsform des erfindungsgemäßen Verfahrens werden Platinen mit einer Bohrung, durch die ein sich über die gesamte Länge des Nadelbettes erstreckender und eine Abschlagskante bildender Abschlagsdraht geführt ist, verwendet und durch Aus- oder Einwärtsbewegen der Platinen die Position des Abschlagsdrahtes und damit der Abschlagskante für die mit der betreffenden Nadel zu bildenden Masche bezüglich des Scheitels des Nadelgrundes entsprechend der gewünschten Maschengröße und den Eigenschaften des Strickfadens optimiert. Durch die Optimierung des Maschenabschlagens wird der günstigste Zeitpunkt des Aufgleitens der alten Masche auf die Maschenschenkel der neuen Masche in Abhängigkeit von der Maschengröße und der Materialart des Strickfadens erreicht.In a further preferred embodiment of the invention Processes are made with a hole through which extends over the entire length of the needle bed and a tapping wire forming a tapping edge is guided, used and by moving the Circuit boards the position of the tee wire and thus the tee edge for those to be formed with the needle in question Stitch accordingly with respect to the apex of the needle base the desired stitch size and the properties of the knitting thread optimized. By optimizing the knitting will be the most convenient time for the old stitch to slide open depending on the stitch legs of the new stitch the stitch size and material type of the knitting thread.

Die erfindungsgemäße Flachstrickmaschine zur Durchführung des erfindungsgemäßen Verfahrens nach einem der Ansprüche 1 bis 3 ist Gegenstand von Anspruch 4. Die Platinen können gleichzeitig die Funktion von Maschenbildern übernehmen. Es kann jedoch auch neben jeder Platine ein Maschenbilder angeordnet sein, wobei die Wirkflächen der Maschenbilder und der Platinen identisch ausgebildet sind. Soll außerdem die Abschlagskante für die Maschen verstellbar sein, so können die Platinen mit einer Bohrung versehen sein, durch die ein sich längs des Nadelbettes erstreckender, als Abschlagskante dienender Abschlagsdraht geführt ist. Die Position dieses Drahtes lässt sich verstellen, indem die Platine parallel zur Nadellängsrichtung bewegt wird.The flat knitting machine according to the invention for performing the Method according to the invention according to one of claims 1 to 3 is the subject of claim 4. The boards can at the same time take on the function of stitch patterns. It However, a mesh pattern can also be arranged next to each board be, the effective surfaces of the stitch patterns and the Boards are identical. Should also be the tee adjustable for the stitches, so the Boards must be provided with a hole through which a extending along the needle bed, serving as a tapping edge Towing wire is guided. The position of this wire can be adjusted by placing the board parallel to the longitudinal direction of the needle is moved.

Nachfolgend werden bevorzugte Ausführungsformen von Platinen erfindungsgemäßer Flachstrickmaschinen und ihre Wirkungsweise anhand der Zeichnung näher beschrieben.Below are preferred embodiments of circuit boards Flat knitting machines according to the invention and their mode of operation described in more detail with reference to the drawing.

Fig. 1 zeigt in der Draufsicht ein Nadelbett mit mehreren Stricknadeln 5, Maschenbildern 6 sowie in Längsrichtung der Nadeln 5 beweglichen Platinen 3. In Fig. 1 a) befinden sich die Stricknadeln in der tiefsten Einzugsposition für die herzustellende Maschengröße. Fig. 1 b) zeigt drei Stricknadeln 5, die unterschiedlich weit in Richtung Kammgleiche ausgetrieben sind. Die Platinen 3 sind entsprechend dem Vortrieb der Stricknadeln 5 ebenfalls unterschiedlich weit aus ihrer Ausgangsstellung ausgetrieben. In Fig. 1 c) ist dann derjenige Zustand dargestellt, in dem alle Nadeln 5 in Kammgleiche und die Platinen 3 wieder in Ausgangsposition sind, in der sie sich in gleicher Höhe wie die Maschenbilder 6 befinden.Fig. 1 shows a top view of a needle bed with several Knitting needles 5, 6 stitch patterns and in the longitudinal direction of Needles 5 movable sinkers 3. In Fig. 1 a) are the knitting needles in the lowest feed position for the one to be manufactured Mesh size. 1 b) shows three knitting needles 5, which are driven out to the same extent in the direction of the comb are. The boards 3 are in accordance with the propulsion of the Knitting needles 5 also differ in their initial position expelled. In Fig. 1 c) is the one State shown in which all needles 5 in comb and the boards 3 are back in the starting position in which they are at the same height as the stitch patterns 6.

Die Wirkungsweise der Platinen 3 und der Stricknadeln 5 in den unterschiedlichen Abschnitten der Maschenbildung ist in den Fig. 2 bis 4 anhand von Schnittbildern durch das Nadelbett aus Fig. 1 dargestellt.The operation of the sinkers 3 and the knitting needles 5 in the different sections of the stitch formation is in the 2 to 4 based on sectional images through the needle bed Fig. 1 shown.

In Fig. 2 ist mit 1 ein Nadelbettsteg bezeichnet, der eine Nut 2 aufweist, in den die Platine 3 parallel zur Nadelgleitebene angeordnet und durch den Schaft der Nadel 5 seitlich fixiert ist. Die Wirkfläche 4 an der Platinenbrust weist dieselbe Geometrie wie die Wirkfläche 7 des gestrichelt eingezeichneten Maschenbilders 6 auf, der seitlich neben der Platine 3 liegt. Die Platine 3 wird durch eine nicht näher dargestellte Kurvenbahn an einem über das Nadelbett bewegten Schlitten gesteuert. In Fig. 2 übt die Kurvenbahn eine Kraft K1 aus, die bewirkt, dass die Wirkfläche 4 der Platine 3 in einer Ebene zur Wirkfläche 7 des Maschenbilders 6 liegt. Die Nadel 5 wird von einer Nadelschlosskurve des Schlittens in Richtung des Pfeiles NE in das Nadelbett eingezogen, wodurch sich eine Maschenschleife 9 eines in den Nadelhaken 8 eingelegten Strickfadens gleichzeitig an den Wirkflächen 4 und 7 abstützt. Die zuvor gebildete Masche 10 liegt mit ihrem Bogen 11 über den Schenkeln der Maschenschleife 9 und überträgt dadurch auf die Maschenschleife 9 eine Abzugskraft AK einer nicht näher dargestellten Gestrickabzugseinrichtung. Die Nadel 5 befindet sich in Fig. 2 an der tiefsten Einzugsposition, die zur Erzeugung der gewünschten Maschengröße nötig ist.In Fig. 2, 1 denotes a needle bed web, the one Has groove 2, in which the board 3 parallel to the needle sliding plane arranged and laterally through the shaft of the needle 5 is fixed. The active surface 4 on the board breast has the same Geometry like the active surface 7 of the dashed line Stitcher 6 on the side of the board 3 lies. The board 3 is by a not shown Cam track on one moved over the needle bed Sled controlled. In Fig. 2, the cam track exercises one Force K1, which causes the active surface 4 of the circuit board 3 lies in a plane to the active surface 7 of the stitch former 6. The needle 5 is in a needle lock curve of the carriage in In the direction of arrow NE drawn into the needle bed, whereby a stitch loop 9 inserted into the needle hook 8 Knitting thread simultaneously on the knitting surfaces 4 and 7 supported. The previously formed stitch 10 lies with its arch 11 over the legs of the loop 9 and transmits thereby a pull-off force AK one on the loop 9 Knitting device not shown. The needle 5 is in Fig. 2 at the lowest feed position, which is necessary to create the desired mesh size.

In Fig. 3 wird die Nadel 5 durch die Nadelschlosskurve mit einer auswärtsgerichteten Kraft NV beaufschlagt und somit nach vorne ausgetrieben. Gleichzeitig wird die Platine 3 durch die zugehörige Steuerkurve mit der Kraft K2 mit gleicher Geschwindigkeit wie die Nadel 5 mitausgetrieben. Dadurch verschiebt sich die Wirkfläche 4 der Platine 3 gegenüber der Wirkfläche 7 des Maschenbilders 6 nach vorne und hält die Schenkel der Maschenschleife 9 während der Vorwärtsbewegung der Nadel 5 gespannt. Dadurch wird sicher vermieden, dass die Maschenschleife 9 aus dem Nadelhaken 8 springen kann. Vorteilhafterweise wird die Platine 3 nur solange mitausgetrieben, bis der Beschleunigungsruck der Stricknadel 5 durch die Wirkung des Gestrickabzugs kompensiert ist und damit die Maschenschleife 9 allein durch die Kräfte des Gestrickabzugs im Nadelhaken 8 gehalten wird.In Fig. 3, the needle 5 with the needle lock curve an outward force NV and thus after driven out at the front. At the same time, the board 3 through the associated control curve with the force K2 at the same speed like the needle 5 driven out. This shifts the active surface 4 of the circuit board 3 is opposite the active surface 7 of the stitch former 6 to the front and holds the legs of the Mesh loop 9 stretched during the forward movement of the needle 5. This will surely avoid the stitch loop 9 can jump out of the needle hook 8. advantageously, the board 3 is driven out only until the acceleration jerk the knitting needle 5 by the action of Knitted fabric deduction is compensated and thus the loop 9 solely by the forces of the knitted fabric in the needle hook 8 is held.

In Fig. 4 ist dargestellt, wie die Nadel 5 durch die Kraft NV weiter nach vorne bis zum Erreichen der Kammgleiche ausgetrieben wird. Die Platine 3 wird dagegen durch die Kraft K3 der zugeordneten Platinenschlosskurve bereits wieder eingezogen, nachdem der Gestrickabzug dafür sorgt, dass die Maschenschleife 9 sicher im Nadelhaken 8 gehalten wird. Die Einzugsbewegung wird solange fortgesetzt, bis die vordere Wirkfläche 4 der Platine 3 wieder in einer Ebene mit der Wirkfläche 7 des Maschenbilders 6 liegt und die Platine 3 damit wieder ihre Ausgangsposition erreicht hat. Damit ist die Maschenbildung abgeschlossen. Zur erneuten Bildung einer Masche werden die in den Fig. 2 bis 4 dargestellten Schritte erneut durchgeführt. In Fig. 4 it is shown how the needle 5 by the force NV continue to drive out until the ridge equilibrium is reached becomes. The board 3, however, is by the force K3 assigned board lock curve already retracted, after the knitted fabric trigger ensures that the stitch loop 9 is held securely in the needle hook 8. The feed movement is continued until the front active surface 4 of the Board 3 again in one plane with the active surface 7 of the stitch former 6 lies and the board 3 thus again its starting position has reached. This completes the stitch formation. To re-form a stitch, the in the Fig. 2 to 4 steps performed again.

Fig. 5 zeigt eine zweite Ausführungsform einer Platine 30 in derselben Position wie die Platine 3 in Fig. 2. Die Platine 30 ist hier zugleich Maschenbilder und Spannelement für eine Maschenschleife 90. Die Lagerung der Platine 30 erfolgt wieder in einer Nut 20 eines Nadelbettsteges 12. Die Geometrie der stirnseitigen Wirkfläche 40 der Platine 30 ist ebenfalls identisch zur Geometrie der Wirkfläche 4 der Platine 3. Auch die Bewegungsabläufe der Platine 30 sowie der Stricknadel 50 sind identisch zu denjenigen der Platine 3 und der Nadel 5. Zweckmäßigerweise ist jedoch die Platine 30 dicker als die Platine 3, vorzugsweise so dick wie die Platine 3 und der Maschenbilder 6 zusammen.5 shows a second embodiment of a circuit board 30 in the same position as the board 3 in FIG. 2. The board 30 is here both mesh patterns and tensioning elements for a loop 90. The board 30 is stored again in a groove 20 of a needle bed web 12. The geometry of the frontal active surface 40 of the board 30 is also identical to the geometry of the active surface 4 of the circuit board 3 Movements of the circuit board 30 and the knitting needle 50 are identical to those of the board 3 and the needle 5. Conveniently however, the board 30 is thicker than the board 3, preferably as thick as the board 3 and the stitch patterns 6 together.

Wie insbesondere Fig. 1 a) zeigt, kann die Maschengröße nicht nur durch eine entsprechende Einzugstiefe der Stricknadeln 5 bzw. 50 beeinflusst werden, sondern auch durch einen Austrieb der Platinen 3 bzw. 30. Wäre die Platine 3 in Fig. 1 etwas weiter nach vorne ausgetrieben, so würden sich dadurch größere Maschen bilden, da der Strickfaden um die Platinen 3 herum eingezogen werden muss. So kann also bei konstanter Einzugstiefe der Nadeln 5 bzw. 50 durch eine entsprechende Austriebsposition der Platinen 3 oder 30 die Maschengröße beeinflusst werden.As FIG. 1 a) in particular shows, the mesh size cannot only by a corresponding retraction depth of the knitting needles 5 or 50 can be influenced, but also by sprouting of the boards 3 and 30 would be the board 3 in Fig. 1 something expelled further forward, so that would become larger Form stitches because the knitting thread around the sinkers 3 must be drawn in. So with a constant feed depth the needles 5 and 50 by a corresponding expulsion position the sinker 3 or 30 affects the mesh size become.

Fig. 6 zeigt eine weitere Variante einer Platine 3', die wieder in einer Nut 2' eines Nadelbettsteges 1' gelagert ist. Die Brustfläche 4' der Platine 3' dient als Maschenbilder. In der Nähe der Brustfläche 4' weist die Platine 3' eine Bohrung auf, durch die ein Abschlagsdraht 14 geführt ist. Der Abschlagsdraht 14 erstreckt sich über die gesamte Länge des Nadelbettes und bildet eine Abschlagskante. Der Fuß 15 der Platine 3' ist wieder durch eine Platinenschlosskurve beaufschlagbar. In dargestellter Platinenposition ist der Fuß 15 so beaufschlagt, dass sich der Abschlagsdraht 14 in einer Grundposition GP befindet, die für die betreffende Maschinenfeinheit für die Herstellung von Maschen normaler Größe mit einem durchschnittlichen Strickfaden einen idealen Abstand vom Scheitel des Nadelgrundes SNG aufweist. Sollen jedoch andere Maschengrößen gebildet und/oder andere Strickgarnqualitäten verwendet werden, so kann die Lage des Abschlagsdrahtes 14 durch entsprechendes Verschieben der Platine 3' in Pfeilrichtung + oder in Pfeilrichtung - verändert werden, um damit ideale Bedingungen für das Maschenabschlagen zu schaffen. Dabei kann die Anpassung der Lage des Abschlagsdrahtes 14 nadelgenau erfolgen. Dies ist dann wichtig, wenn innerhalb eines Gestricks in einzelnen Abschnitten Maschen anderer Größe gebildet oder unterschiedliches Strickgarn verwendet wird.Fig. 6 shows a further variant of a circuit board 3 ', which again is stored in a groove 2 'of a needle bed web 1'. The Chest surface 4 'of the board 3' serves as a mesh. In the The board 3 'has a bore near the chest surface 4', through which a tapping wire 14 is passed.
