Description

Seit es Flachstrickmaschinen gibt, wird die Vortriebs- und Rückzugsbewegung der Stricknadeln durch Strickschlösser bewirkt. Diese Strickschlösser besitzen Kurvenbahnen (Schlossdurchgänge), in welche die Nadelfüße eingreifen. Sobald die Strickschlösser in Maschinenlängsrichtung verschoben werden, bewegen sich die Stricknadeln quer zur Maschinenlängsachse.Since there are flat knitting machines, the propulsion and retraction movement of the knitting needles is effected by knitting locks. These knitting locks have curved tracks (lock passages) in which the needle feet engage. Once the knitting locks are moved in the machine longitudinal direction, the knitting needles move transversely to the machine longitudinal axis.

Schon in der frühen Entwicklung der Flachstrickmaschine wurde die Notwendigkeit erkannt, dass es unterschiedliche Vortriebswege für die Stricknadel geben muss.Already in the early development of the flat knitting machine, the necessity was recognized that there must be different driving paths for the knitting needle.

In der DE 7777 ist ein Nadelaustriebsteil beschrieben, welches in vertikaler Richtung verschoben werden kann und somit unterschiedliche Austriebswege der Nadel ermöglicht.In DE 7777 a Nadelaustriebsteil is described, which can be moved in the vertical direction and thus allows different Austriebswege the needle.

Durch die DE 21412 ist ein zweiteiliges Nadelaustriebsteil bekannt geworden. Ein Unterteil ist starr mit einer Schlossplatte verbunden. Ein Oberteil ist in vertikaler Richtung nach oben verschiebbar. Befindet sich das Oberteil in seiner unteren Position, so erfolgt der größte Nadelaustrieb. Befindet es sich in seiner oberen Position, so öffnet sich ein Schlossdurchgang, durch welchen die Nadeln nur auf 1/3 ihrer maximalen Austriebshöhe ausgetrieben werden.By the DE 21412 a two-part Nadelaustriebsteil has become known. A lower part is rigidly connected to a lock plate. An upper part is vertically displaceable upwards. If the upper part is in its lower position, the largest needle ejection takes place. If it is in its upper position, then a lock passage opens, through which the needles are expelled only to 1/3 of their maximum shoot height.

Zum Stand der Technik gehören Strickschlösser, bei denen mittels örtlich übereinander liegender Schlossdurchgänge die unterschiedlichen Nadelaustriebe, z. B. für Fang-Masche-Übergeben, realisiert werden.The prior art include knitting locks in which by means of locally superimposed castle passages the different needle drives, z. B. for Fang-Maschen-handed over, be realized.

Die einzelnen Schlossdurchgänge unterscheiden sich durch unterschiedliche Eingriffshöhen auf die Füße der Nadeln. Bei bekannten Strickschlosskonstruktionen werden die Nadelfüße durch gesteuerte Drückerelemente in ihre Höhenposition gebracht. (siehe DE 3537612 ). Die möglichen Höhenpositionen der Nadelfüße reichen von gänzlich im Nadelkanal versenkt bis zur vollen Fußhöhe, welche aus dem Nadelkanal ragt.The individual castle passages differ by different engagement heights on the feet of the needles. In known cam lock constructions, the needle feet are brought into their height position by controlled pusher elements. (please refer DE 3537612 ). The possible height positions of the needle feet ranging from completely submerged in the needle channel to the full foot height, which protrudes from the needle channel.

Da es bei den Strickschlössern, entsprechend dem geschilderten Stand der Technik, Schlossdurchgänge gibt, bei denen der Nadelfuß nicht in voller Höhe eingreifen kann, erhöht sich die Flächenpressung mit abnehmender Eingriffshöhe des Nadelfußes. Die Erhöhung der Flächenpressung vergrößert den Verschleiß an den Nadelfüßen und an den Schlossteilen, welche den Schlossdurchgang bilden. Diese Erhöhung des Verschleißes ist ein nachteiliger Aspekt der Strickschlösser entsprechend dem Stand der Technik.Since there are lock passages in the knitting locks, according to the described prior art, in which the needle butt can not fully engage, the surface pressure increases with decreasing engagement height of the needle butt. The increase in the surface pressure increases the wear on the needle feet and on the lock parts, which form the lock passage. This increase in wear is a disadvantageous aspect of prior art knitting locks.

Die DE-A-3327093 beschreibt ein Strickschloss für Schiebernadeln, das eine Dreiwegetechnik realisiert, d. h. bei dem die Nadeln abhängig von der Stelle ihrer Auswahl im Strickschloss eine Masche bilden, einen Fanghenkel bilden oder gar nicht am Strickvorgang teilnehmen. Die verschiedenen Schlossdurchgänge werden durch vier Schlossteile begrenzt, wobei zwei der Schlossteile nur bei der Schlittenumkehr und nur gemeinsam, aber nicht relativ zueinander verstellbar sind. Dieses als Drückerschloss ausgeführte Strickschloss ist im Aufbau aufwändig. Die Schlossdurchgänge weisen überwiegend eine Breite auf, die der Nadelfußbreite entspricht.The DE-A-3327093 describes a knitting lock for sliding needles, which implements a three-way technique, ie in which the needles form a loop depending on the point of their selection in the knitting lock, form a tuck or do not participate in the knitting process. The various castle passages are limited by four castle parts, with two of the castle parts only in the carriage reversal and only together, but not relative to each other are adjustable. This knitting lock designed as a pusher lock is complex in construction. The castle passages predominantly have a width corresponding to the needle foot width.

Der Erfindung liegt die Aufgabe zugrunde, ein Strickschloss mit mindestens zwei Schlossdurchgängen zu entwickeln, welches konstruktiv einfach ist und einen möglichst geringen Verschleiß an den Nadelfüßen und an den Schlossteilen aufweist.The invention has for its object to develop a knitting lock with at least two castle passages, which is structurally simple and has the least possible wear on the needle feet and on the lock parts.

Diese Aufgabe wird durch ein Strickschloss mit den Merkmalen des Anspruchs 1 gelöst. Die Nadelfüße müssen zum Passieren eines Schlossdurchgangs nicht in eine gewisse Höhenposition gebracht werden. Die Nutzung der vollen Nadelfußhöhe reduziert den konstruktiven Aufwand und den Verschleiß.This object is achieved by a knitting lock with the features of claim 1. The needle feet need not be brought into a certain height position for passing a lock passage. The use of the full needle foot height reduces the design effort and wear.

Das Steuerteil bildet eine Art Weiche für die Nadelfüße. Es kann eine paarweise Anordnung und Verschiebung von Steuerteilen vorgesehen sein. Werden für eine Strickschlosskonfiguration mehr als zwei übereinander liegende Schlossdurchgänge benötigt, so können die Steuerteilpaare mehrfach übereinander angeordnet werden.The control part forms a kind of switch for the needle feet. There may be a paired arrangement and displacement of control parts. If more than two superimposed lock passages are required for a knitting cam configuration, the control pairs can be arranged several times one above the other.

Auf die Breite mindestens eines der Schlossdurchgänge und damit auf das Spiel der Nadelfüße kann durch die Bewegungsrichtung des Steuerteils Einfluss genommen werden. Wenn das beispielsweise als Winkelstück ausgebildete Steuerteil eine identische Kontur zu den Schlossteilinnenflächen aufweist und in Richtung der Winkelhalbierenden des Winkels zwischen zwei Flächen des Steuerteils bewegt wird, bildet sich ein Schlossdurchgang einer einzigen Breite aus. Wenn eine von der Winkelhalbierenden abweichende Bewegungsrichtung gewählt wird, beispielsweise senkrecht zu einer der Flächen des Steuerteils, bildet sich ein Schlossdurchgang mit einem Abschnitt einer ersten Breite und einem Abschnitt einer hierzu unterschiedlichen zweiten Breite. Ob nun die erste oder die zweite Breite größer ist, richtet sich nach den Flächen des Steuerteils bzw. der Bewegungsrichtung bezüglich der Flächen. Je nach der ausgebildeten Breite werden Nadelfüße enger oder weiter gefasst. Dies wirkt sich auf die Nadelfunktion und den Verschleiß aus.On the width of at least one of the castle passages and thus on the game of the needle feet can be influenced by the direction of movement of the control part. If, for example, the control part formed as an angle piece has an identical contour to the lock part inner surfaces and is moved in the direction of the bisector of the angle between two surfaces of the control part, a lock passage of a single width is formed. If a different direction of movement of the bisector is selected, for example, perpendicular to one of the surfaces of the control part, a lock passage forms with a portion of a first width and a portion of a different second width. Whether the first or the second width is greater, depends on the areas of the control part or the direction of movement with respect to the surfaces. Depending on the trained width needle feet are narrower or wider. This affects the needle function and the wear.
