Description

Die Erfindung betrifft eine Verstellvorrichtung für Schlossteile von Flachstrickmaschinen, insbesondere für die Abzugsund Druckschlossteile eines Schlosssystems des Maschinenschlittens.The invention relates to an adjusting device for lock parts of flat knitting machines, in particular for the take-off and Push lock parts of a locking system of the machine slide.

Aufgrund der hin- und hergehenden Bewegung des Maschinenschlittens haben die Schlosssysteme des Maschinenschlittens zur Beeinflussung der Nadelbewegungen einen weitgehend symmetrischen Aufbau. Bei modernen Hochleistungsflachstrickautomaten, die vornehmlich mit Druckschlössern ausgerüstet sind, kann für jede einzelne Nadel bestimmt werden, ob eine Masche oder ein Fang gebildet wird, ob sie eine Masche übergibt oder übernimmt, ob sie einen Splitstitch ausführt oder ob sie überhaupt nicht am Strickvorgang teilnimmt. Außerdem kann die Maschengröße, die durch die einzelnen Nadeln erzeugt wird, für jede einzelne Nadel getrennt vorgegeben werden. Hierzu ist es erforderlich, verschiedene Schlossteile in bestimmte Positionen zu bewegen und in diesen zu halten. Da die Schlossteile zusammenwirken, ist außerdem eine koordinierte Verstellung der einzelnen Schlossteile notwendig. Due to the reciprocating movement of the machine slide have the lock systems of the machine slide largely to influence the needle movements symmetrical structure. With modern high-performance flat knitting machines, mainly equipped with pressure locks , it can be determined for each individual needle whether a Stitch or a catch is formed whether it passes a stitch or takes over whether she carries out a split stitch or whether she does not participate in the knitting process at all. Besides, can the stitch size created by the individual needles, can be specified separately for each individual needle. This is it required different lock parts in certain positions to move and hold in this. Because the castle parts cooperate is also a coordinated adjustment of the individual lock parts necessary.

Es ist bekannt, für jedes der beweglichen Schlossteile eine eigene Bewegungseinrichtung, beispielsweise einen Schrittmotor oder einen Schaltmagneten, vorzusehen. Dies erfordert jedoch einen hohen Steuerungsaufwand und einen großen Einbauraum, der bei Hochleistungsflachstrickmaschinen mit mehreren Schlosssystemen häufig nicht vorhanden ist.It is known to have one for each of the movable lock parts own movement device, for example a stepper motor or a switching magnet. However, this requires a high control effort and a large installation space that in high-performance flat knitting machines with multiple lock systems is often absent.

In der DE 43 37 775 A1 ist eine Verstellvorrichtung für Schlossteile beschrieben, die eine gemeinsame Verstellung mehrerer Schlossteile erlaubt, jedoch nicht ausreichend ist, die Schlossteile von Strickschlössern mit erweiterten Strickfunktionen anzusteuern.DE 43 37 775 A1 describes an adjustment device for Lock parts described that have a common adjustment several lock parts allowed, but not sufficient, the lock parts of knitted locks with extended knitting functions head for.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Verstellvorrichtung für Schlossteile von Flachstrickmaschinen zu schaffen, die bei möglichst kleinem Einbauraum und geringem steuerungstechnischem Aufwand in der Lage ist, alle Schlossteile von Schlössern mit erweiterten Strickfunktionen zu positionieren.The present invention has for its object a Adjustment device for lock parts of flat knitting machines to create that with the smallest possible installation space and small control engineering effort is able to all lock parts of locks with advanced knitting functions.

Die Aufgabe wird mit einer Verstellvorrichtung der eingangs genannten Art gelöst, die gekennzeichnet ist durch zwei Schrittmotoren, wobei ein Abtriebsritzel des ersten Schrittmotors gleichzeitig und gegensinnig auf zwei in Schlittenlaufrichtung verstellbare Steuerschieber einwirkt, die Steuerflächen von ersten Schlossteilen beaufschlagen, und wobei ein Abtriebsritzel des zweiten Schrittschaltmotors auf einen in Schrittrichtung verstellbaren Kurvenschieber einwirkt, der mit Steuerkurven mindestens für zweite und dritte Schlossteile versehen ist. Mit nur zwei Schrittmotoren lassen sich somit mindestens erste, zweite und dritte Schlossteile, die beispielsweise die Abzugschlossteile, die Druckschlossteile und Verstellelemente für mit den Abzugsschlossteilen zusammenwirkende Kulierelemente sein können, koordiniert verstellen. Die beiden Schrittschaltmotoren benötigen im Vergleich zum Einzelantrieb aller Schlossteile nur einen geringen Einbauraum und sind vergleichsweise einfach anzusteuern.The task is started with an adjustment device resolved type, which is characterized by two Stepper motors, wherein an output pinion of the first stepper motor simultaneously and in opposite directions on two in the direction of the sledge adjustable control slide acts on the control surfaces acted upon by the first parts of the lock, and being a Output pinion of the second stepper motor to an in Step direction adjustable cam slider acts with Control curves for at least second and third lock parts is provided. With just two stepper motors, at least first, second and third lock parts, for example the trigger lock parts, the pressure lock parts and Adjustment elements for interacting with the trigger lock parts Adjustment elements can be coordinated. The Both stepper motors need compared to the single drive all lock parts only a small installation space and are comparatively easy to control.

Die Abtriebsritzel der beiden Schrittmotoren können vorzugsweise formschlüssig direkt auf die Steuer- und Kurvenschieber einwirken. Dazu können die Steuer- und Kurvenschieber vorzugsweise mit Zahnleisten versehen sein.The output pinion of the two stepper motors can preferably form-fitting directly on the control and cam spool act. For this purpose, the control and cam slides can preferably be provided with toothed racks.

Für eine reibungsarme Verstellung können die zwei Steuerschieber über Kulissenrollen die Steuerflächen der ersten Schlossteile beaufschlagen. Ebenso können die zweiten und dritten Schlossteile mit Kulissenrollen versehen sein, die durch die Steuerkurven des Kurvenschiebers führbar sind. Zur Ermöglichung von Schwenkbewegungen der Schlossteile oder auch von Linearbewegungen senkrecht zur Schlittenlaufrichtung können die Steuerkurven des Kurvenschiebers mindestens teilweise abweichend von der Schlittenlaufrichtung verlaufende Kurvenabschnitte aufweisen.The two control slides can be used for low-friction adjustment the control surfaces of the first parts of the castle are connected by roller wheels apply. Likewise, the second and third Lock parts are provided with backdrop rollers, which by the Control curves of the cam spool are feasible. To make it possible of pivoting movements of the lock parts or of Linear movements perpendicular to the direction of slide travel can the control cam of the cam spool at least partially curve sections that deviate from the direction of the slide exhibit.

Nachfolgend wird anhand der Zeichnungen ein bevorzugtes Ausführungsbeispiel einer erfindungsgemäßen Verstellvorrichtung und ihre Verstellmöglichkeit von Schlossteilen näher beschrieben.A preferred embodiment is described below with reference to the drawings an adjustment device according to the invention and their adjustment of lock parts described in more detail.

An der Schlossplatte 80 sind außerdem zwei Drückerleisten 5 und 6 angeordnet. Die Drückerleiste 5 ist zwischen der Arbeitsposition 5 und einer Außertätigkeitsposition 5' und die Drückerleiste 6 zwischen der Arbeitsposition 6, einer ersten Außertätigkeitsposition 6' und einer zweiten Außertätigkeitsposition 6'' verstellbar. An den Drückerleisten bzw. an den Verbindungsteilen zwischen den Drückerleisten 5 und 6 sind Rollen 50 und 60 angeordnet, über die eine Verstellung der Drückerleisten 5 und 6 möglich ist.There are also two pusher bars 5 on the lock plate 80 and 6 arranged. The pusher bar 5 is between the working position 5 and a non-employment position 5 'and the Pusher bar 6 between the working position 6, a first Out of work position 6 'and a second out of work position 6 '' adjustable. On the pusher bars or on the Connection parts between the pusher bars 5 and 6 are Rollers 50 and 60 arranged via an adjustment of the Pusher bars 5 and 6 is possible.

Durch eine entsprechende Verstellung der Nadelsenker 1, 3, der Kulierelemente 2, 4 sowie der Drückerleisten 5, 6 und einer nicht dargestellten Nadelauswahlvorrichtung lassen sich die verschiedenen möglichen Stricktechniken realisieren.By appropriate adjustment of the needle countersink 1, 3, the Kulierelemente 2, 4 and pusher bars 5, 6 and one The needle selection device, not shown, can be realize various possible knitting techniques.

Zum Stricken einer schlanken Masche wie beim Rechts-Rechts-Gestrick befinden sich der Nadelsenker 1 und das Kulierelement 2 in der in Fig. 1 dargestellten Grundposition. Der Nadelsenker 3 wird entsprechend der gewünschten Maschengröße in Arbeitsposition nach außen geschoben. Das Kulierelement 4 bleibt in seiner Grundposition. Die Drückerleiste 5 bleibt in Arbeitsposition, während die Drückerleiste 6 in ihre Außertätigkeitsposition 6' verstellt wird.For knitting a slim stitch like the right-right knitted fabric are the needle counterbore 1 and the wedge element 2 in the basic position shown in Fig. 1. The countersink 3 will be in the working position according to the desired mesh size pushed outwards. The Kulierelement 4 remains in its basic position. The pusher bar 5 remains in the working position, while the pusher bar 6 in its idle position 6 'is adjusted.

Soll eine rundliche Masche wie beim Glatt-Gestrick erzeugt werden, so verbleiben die Nadelsenker 1 und 2 in Grundposition, der Nadelsenker 3 wird in Arbeitsposition entsprechend der gewünschten Maschengröße nach außen bewegt und das Kulierelement 4 in Arbeitsposition, d. h. in seine äußerste Position, geschwenkt. Die Drückerleiste 5 ist wieder in Arbeitsposition und die Drückerleiste 6 in Außertätigkeitsposition 6'. Durch das Verschwenken des Kulierelements 4 entsteht eine breitere Kulierfläche, die das mehr rundliche Aussehen der Masche bewirkt. Should create a rounded stitch like the smooth knitted fabric the needle countersinks 1 and 2 remain in the basic position, the needle counterbore 3 is correspondingly in the working position the desired mesh size moves out and the Kulierelement 4 in working position, d. H. to its extreme position, pivoted. The pusher bar 5 is again in the working position and the pusher bar 6 in the idle position 6 '. By pivoting the Kulierelements 4 arises a wider cul area that gives the more rounded look the stitch causes.

The stepper motor 92 thus serves and the sliders 100 and 200 for the adjustment of the needle counterbores 1 and 3 as trigger lock parts.

Das Zahnritzel 95 des Motors 94 bildet einen Formschluss mit einer Zahnleiste des Kurvenschiebers 300, in den vier Kurvenbahnen 320, 340, 350 und 360 eingearbeitet sind. In die Kurvenbahn 320 greift die Rolle 20 des Schlossteils 22 zur Verstellung des Kulierelements 2 und in die Kurvenbahn 340 die Rolle 40 des Schlossteils 42 zur Verstellung des Kulierelements 4 ein. In die Kurvenbahn 350 greift die Rolle 50 der Drückerleiste 5 ein. Die Rolle 60 der Drückerleiste 6 wird in der Kurvenbahn 360 geführt. Die Kurvenbahnen 320, 340, 350 und 360 weisen alle von der Waagerechten und damit der Schlittenlaufrichtung abweichende Kurvenabschnitte auf, wodurch die Bewegung der Schlossteile 1, 3, 22, 42, 5 und 6 aus Fig. 1 in den dort dargestellten Pfeilrichtungen möglich ist.The pinion 95 of the motor 94 forms a positive connection a rack of the cam slide 300, in the four cam tracks 320, 340, 350 and 360 are incorporated. In the curve path 320 engages the roller 20 of the lock part 22 for adjustment of the Kulierelements 2 and in the curved path 340 die Roller 40 of the lock part 42 for adjusting the wedge element 4 a. The roller 50 engages in the cam track 350 Pusher bar 5 on. The role 60 of the pusher bar 6 is in the curved path 360 out. The cam tracks 320, 340, 350 and 360 all point from the horizontal and thus the direction of the slide deviating curve sections, whereby the Movement of the lock parts 1, 3, 22, 42, 5 and 6 from Fig. 1 in the arrow directions shown there is possible.

Die der Fig. 3 entsprechende Darstellung der Verstellvorrichtung 90 in Fig. 4 zeigt die Einstellung für das Stricken einer schlanken Masche. Der Schrittmotor 92 und mit ihm das Ritzel 93 dreht sich so lange, bis der Schieber 100 diejenige Position erreicht hat, in der die Rolle 101 über die Fläche 30 den Nadelsenker 3 in die für die betreffende Maschengröße erforderliche Kulierposition gebracht hat. Der Schieber 200 bewegt sich dadurch gleichzeitig um die gleiche Strecke in entgegengesetzter Richtung. Dadurch beaufschlagt die Rolle 201 die Fläche 11 des Nadelsenkers 1 nicht. Der Nadelsenker 1 bleibt in einer Grundposition. Der Schrittmotor 94 bewegt über das Ritzel 95 den Kurvenschieber 300 soweit, dass sich die Rollen 40 und 50 in Grundstellung befinden, die Rolle 60 aber durch die Kurvenbahn 360 in eine tiefere Position bewegt wird. Diese Position entspricht der Außertätigkeitsstellung 6' der Drückerleiste 6.The representation of the adjusting device corresponding to FIG. 3 90 in Fig. 4 shows the setting for knitting one slim stitch. The stepper motor 92 and with it the pinion 93 rotates until the slide 100 is one Has reached position in which the roller 101 over the surface 30 the needle counterbore 3 in for the stitch size concerned has brought the required wedge position. The slider 200 thereby moves the same distance in opposite direction. The roller 201 is thereby acted upon the surface 11 of the needle counterbore 1 does not. The needle counterbore 1 remains in a basic position. The stepper motor 94 moves over the pinion 95 the cam slide 300 so far that the Rollers 40 and 50 are in the basic position, but the roller 60 is moved to a lower position by the cam track 360. This position corresponds to the idle position 6 'of Pusher bar 6.

In Fig. 5 ist die Einstellung zur Erzeugung einer Splitstitch-Masche gezeigt. Der Schrittmotor 92 bewegt die Schieber 100 und 200 so lange, bis die Rolle 101 über die Fläche 10 den Nadelsenker 1 in seine tiefste Arbeitsposition bewegt hat und die Rolle 201 über die Fläche 31 den Nadelsenker 3 in die Kulierposition gebracht hat, die der gewünschten Größe der Splitstitch-Masche entpricht. Der Schrittmotor 94 bewegt über das Ritzel 95 den Kurvenschieber 300 so weit, dass sich die Rollen 20 und 40 in Grundstellung befinden. Die Rolle 50 wird durch die Kurvenbahn 350 in eine tiefere Position bewegt, die der Arbeitsposition 5' der Drückerleiste 5 entspricht. Gleichzeitig wird die Rolle 60 durch die Kurvenbahn 360 in ihre tiefste Position bewegt, was der Außertätigkeitsstellung 6'' der Drückerleiste 6 entspricht. Mit nur zwei Schrittmotoren 92 und 94 ist also hier die Verstellung sämtlicher Schlossteile 1, 3, 2, 4 und 5 und 6 auf kleinstem Einbauraum und mit geringem steuerungstechnischem Aufwand möglich.In Fig. 5 is the setting for generating a split stitch stitch shown. The stepper motor 92 moves the slides 100 and 200 until the roller 101 over the surface 10 den Has moved the needle counterbore 1 into its deepest working position and the roller 201 over the surface 31 into the needle counterbore 3 Kulierposition brought that the desired size of the Split stitch stitch corresponds. The stepper motor 94 moves over the pinion 95 the cam slider 300 so far that the Rollers 20 and 40 are in the basic position. The roll turns 50 moved to a lower position by the cam track 350 corresponds to the working position 5 'of the pusher bar 5. simultaneously the roller 60 through the cam track 360 in its lowest position moves what the idle position 6 '' corresponds to the pusher bar 6. With only two stepper motors 92 and 94 here is the adjustment of all lock parts 1, 3, 2, 4 and 5 and 6 in the smallest installation space and with low control engineering effort possible.
