Description

Die Erfindung betrifft eine Verstellvorrichtung für Schloßteile von Flachstrickmaschinen, insbesondere für die gegenläufige Verstellung der beiden Abzugsschloßteile eines Schloßsystemes des Maschinenschlittens, mit einem gemeinsamen, mit dem Maschinenschlitten mitbewegten Schrittschaltmotor, dessen Drehbewegung in eine Längsbewegung in Schlittenhubrichtung übersetzt und über mindestens eine Steuerkurve auf die zu verstellenden Schloßteile übertragen wird.The invention relates to an adjusting device for lock parts of flat knitting machines, especially for the opposite Adjustment of the two trigger lock parts of a lock system of the machine slide, with a common, with the machine slide moving stepper motor, whose Rotational movement in a longitudinal movement in the direction of the slide stroke translated and via at least one control curve towards the adjusting lock parts is transmitted.

Die hin- und hergehende Arbeitsbewegung des Maschinenschlittens einer Flachstrickmaschine bedingt einen weitgehend symmetrischen Aufbau der einzelnen Schloßsysteme aus Schloßteilen, die entweder in der einen Schlittenhubrichtung oder in der anderen Schlittenhubrichtung wirksam sind. Dabei muß auch ein Teil der Schloßteile während des Betriebs der Flachstrickmaschine verstellbar sein. Für bestimmte paarweise auftretende Schloßteile, insbesondere die Abzugsschloßteile, muß dabei auch eine gegenläufige Verstellung der beiden Einzelschloßteile möglich sein.The reciprocating work movement of the machine slide a flat knitting machine requires a largely symmetrical one Structure of the individual lock systems from lock parts, either in one direction of the slide or in the other carriage stroke direction are effective. It must also part of the lock parts during the operation of the flat knitting machine be adjustable. For certain pairs Lock parts, especially the trigger lock parts, must be included also an opposing adjustment of the two individual lock parts to be possible.

Es ist bekannt, jedem einzelnen zu verstellenden Schloßteil ein gesondertes Antriebselement zuzuordnen, beispielsweise einen Schaltmagneten. Aus der GB-A-2 147 616 ist eine Flachstrickmaschine bekannt, bei der jedem Nadelsenker ein separater Schrittmotor zugeordnet ist. Dies erfordert jedoch einen entsprechend hohen Steuerungsaufwand mit einer entsprechenden Vergrößerung der Fehlermöglichkeiten. Es ist auch bekannt, gegenläufig zu bewegende Schloßteile mittels eines gemeinsamen Antriebsorganes gleichzeitig zu verstellen. Hierbei wirkt beispielsweise ein Schrittmotor auf einen mit einer auf beide Schloßteile einwirkenden Steuerkurve versehenen einzelnen Schieber ein (DE 35 41 171 A, EP 311 564 A, DE 26 22 883 A). Hierbei hat sich als nachteilig herausgestellt, daß wegen dieses gemeinsamen Steuerschiebers der Verstellweg beider Schloßteile über ihren gesamten möglichen Stellbereich festgelegt ist und bei Bedarf keine zusätzliche Einzelverstellung der beiden Schloßteile möglich ist.It is known to adjust each individual lock part assign a separate drive element, for example a switching magnet. GB-A-2 147 616 is a flat knitting machine known, with each countersink a separate Stepper motor is assigned. However, this requires one correspondingly high control effort with a corresponding Enlargement of the possibility of errors. It is also known lock parts to be moved in opposite directions by means of a common one Drive element to adjust at the same time. This works for example a stepper motor on one with one on both Individual cam control cam provided Slide a (DE 35 41 171 A, EP 311 564 A, DE 26 22 883 A). It has been found to be disadvantageous because of this common spool the adjustment path of both Lock parts defined over their entire possible setting range is and if necessary no additional individual adjustment of the two parts of the lock is possible.

Der Erfindung liegt nun die Aufgabe zugrunde, eine Verstellvorrichtung für Schloßteile von Flachstrickmaschinen, die einen gemeinsamen Verstellmotor für mehrere Schloßteile aufweisen, so auszubilden, daß innerhalb eines vorgegebenen Gesamtverstellschemas, neben Einzelverstellschritten auch eine gemeinsame Verstellung in einzelnen vorgegebenen Stufen erfolgen kann.The invention is based on the object of an adjusting device for lock parts of flat knitting machines, the have a common adjustment motor for several lock parts, to be designed in such a way that within a given overall adjustment scheme, in addition to individual adjustment steps common adjustment in individual predetermined levels can.

Die gestellte Aufgabe wird mit einer Verstellvorrichtung der eingangs genannten Art erfindungsgemäß mit den aus dem kennzeichnenden Teil des Hauptanspruches ersichtlichen Merkmalen gelöst.The task is performed with an adjustment device initially mentioned type according to the invention with the from the characterizing Features evident in the main claim solved.

Durch die Aufteilung eines bisher bekannten einzelnen Steuerschiebers in mehrere gesonderte und mindestens teilweise auch gegenläufig verstellbare erste Steuerschieber, die auf zweite Steuerschieber einwirken, mit welchen die zu verstellenden Schloßteile gekoppelt sind, läßt sich auch eine stufenweise Einzelbewegung von mit einander antriebsmäßig gekoppelter Schloßteile bewirken, wenn auf die zweiten Steuerschieber mehrere erste Steuerschieber einwirken können. Diese Möglichkeit kann für unterschiedliche Schloßteile des Maschinenschlittens einer Flachstrickmaschine vorteilhaft sein, weil mit einer solchen Verstellvorrichtung kompliziertere Verstellbewegungen von Schloßteilen mittels eines einzigen Antriebsorganes, insbesondere eines Schrittschaltmotores, und dementsprechend geringem Einzelsteuerungsaufwand durchgeführt werden können. Besonders vorteilhaft wirkt sich eine solche Verstellvorrichtung bei der erforderlichen gegenläufigen Verstellung der beiden Abzugsschloßteile eines Schloßsystems einer Flachstrickmaschine aus, wo diese gegenläufige Verstellbewegung in Stufen unterteilbar ist.By dividing a previously known single spool in several separate and at least partially oppositely adjustable first spool valve, the second Act control spool with which the to be adjusted Lock parts are coupled, can also be gradually Single movement of drives coupled with each other Lock parts cause when on the second spool can act several first spool. This possibility can be used for different lock parts of the machine slide a flat knitting machine may be advantageous because with such an adjustment device more complicated adjustment movements of lock parts by means of a single drive element, especially a stepper motor, and accordingly low individual control effort can. Such an adjustment device has a particularly advantageous effect with the necessary opposite adjustment the two trigger lock parts of a lock system of a flat knitting machine from where this opposite adjustment movement in Levels can be subdivided.

Vorteilhafterweise kann mindestens einer der direkt vom Schrittschaltmotor angetriebenen beiden ersten Steuerschieber über mindestens ein Kupplungszahnritzel mit mindestens einem weiteren und parallel zu den beiden anderen verstellbaren ersten Steuerschiebern antriebsmäßig gekoppelt sein. Die ersten Steuerschieber können wahlweise mindestens eine Kulissenrolle tragen oder aber mit mindestens einer Führungsbahn für eine Kulissenrolle versehen sein, während die zweiten Schieber mit mindestens zwei Steuerkurven versehen sind, die im gegenseitigen Abstand von zwei ersten Schiebern ausgebildet sind und abweichend von der Schlittenlaufrichtung verlaufende Kurvenabschnitte aufweisen.Advantageously, at least one of the direct from Stepper motor driven two first spool via at least one clutch pinion with at least one further and adjustable parallel to the other two first spool be drivingly coupled. The first Control spools can optionally have at least one sliding block wear or with at least one guideway be provided for a backdrop role, while the second Sliders are provided with at least two control cams formed at a mutual distance from two first slides are and deviating from the direction of the slide Have curve sections.

Bei einer Verstellvorrichtung gemäß der Erfindung, die zur Steuerung von zwei in bekannter Weise spiegelbildlich schräg zur Schlittenlaufrichtung verschiebbar gelagerten Abzugsschloßteilen eines Schloßsystemes vorgesehen ist, können die beiden zweiten und die Abzugsschloßteile tragenden Schieber im Abstand von zwei gegenläufig angetriebenen ersten Schiebern jeweils zwei quer verlaufende Steuerkurven aufweisen, die für den Einlauf und für den Auslauf einer Kulissenrolle beidendig offen sind und jeweils eine Abwinkelung aufweisen, die zwei in der Schlittenlaufrichtung gegeneinander vollständig versetzte Auflauf-Schrägflächen für die Kulissenrollen bilden. Dadurch ist sichergestellt, daß immer nur einer der ersten Steuerschieber auf den zweiten Steuerschieber einwirkt, insgesamt aber innerhalb einer möglichen Gesamtverstellstrecke mehrere erste Steuerschieber den zweiten Steuerschieber beeinflussen können.In an adjusting device according to the invention, for Control of two in a known manner obliquely mirror image Trigger lock parts slidably mounted to the direction of slide travel a lock system is provided, the two second and the trigger lock parts carrying slide in Distance between two oppositely driven first slides each have two transverse control curves that for the inlet and for the outlet of a backdrop roll both ends are open and each have an angle that two in completely offset the direction of the slide Form ramp inclined surfaces for the backdrop rollers. Thereby it is ensured that only one of the first control spools is ever used acts on the second spool, overall but several within a possible total adjustment range first spool affect the second spool can.

Nachfolgend wird als Ausführungsbeispiel eine Verstellvorrichtung anhand der beiliegenden Zeichnung näher beschrieben, die zur gegenläufigen Verstellung der beiden Abzugsschloßteile und zur Beeinflussung von Druckschloßteilen eines Schloßsystems mittels eines einzigen Schrittschaltmotors ausgebildet ist.An adjusting device is described below as an exemplary embodiment described in more detail with reference to the accompanying drawing, the for the opposite adjustment of the two trigger lock parts and for influencing the pressure lock parts of a lock system is formed by means of a single stepping motor.

Die Zeichnung zeigt nur die Verstellvorrichtung mit ihren erfindungswesentlichen Teilen. Sie weist ein aus Fig. 4 ersichtliches Gehäuse 10 auf, das in nicht näher dargestellter Weise auf die Rückseite 11.1 einer Schloßplatte 11 aufgesetzt ist, die auf ihrer Vorderseite 11.2 in bekannter Weise Schloßteile trägt; hier zu verstellende Abzugsschloßteile 12 und zu verstellende Druckschloßteile 13. Die zu verstellenden Schloßteile 12, 13 sind durch Führungsschlitze (z. B. 14) der Schloßplatte 11 hindurch mit auf der Rückseite 11.1 der Schloßplatte 11 angeordneten zweiten Steuerschiebern verbunden. Aus Fig. 4 sind zweite Steuerschieber 16/2 und 16/3 ersichtlich. The drawing shows only the adjustment device with its parts essential to the invention. It has one that can be seen from FIG. 4 Housing 10 on that in not shown Put on the back 11.1 of a lock plate 11 is the lock parts on its front 11.2 in a known manner wearing; trigger lock parts 12 to be adjusted here adjusting pressure lock parts 13. The lock parts to be adjusted 12, 13 are through guide slots (z. B. 14) Lock plate 11 through with on the back 11.1 Lock plate 11 arranged second spool connected. From Fig. 4 second spool 16/2 and 16/3 can be seen.

In dem Gehäuse 10 der Verstellvorrichtung sind drei erste Steuerschieber 15/1, 15/2 und 15/3 parallel zueinander und in Schlittenlaufrichtung verschiebbar gelagert. Ihre Längsseiten sind als Zahnleisten 17 ausgebildet (Fig. 1 - 3), in welche gehäusestationär gelagerte Ritzel 18 und 19 eingreifen und eine gegenseitige und gegenläufige Koppelung benachbarter erster Steuerschieber 15/1 - 15/3 bewirken. Das Ritzel 19 ist auf der Abtriebswelle eines am Gehäuse 10 befestigten Schrittschaltmotors 20 angeordnet, wie das Schnittbild der Fig. 4 zeigt. Aus dem Schnittbild der Fig. 4 ist außerdem zu erkennen, daß die beiden ersten Steuerschieber 15/1 und 15/2 eine kugelgelagerte Kulissenrolle 21 oder 22 tragen, die in Steuerkurven der zweiten Steuerschieber ragen, während der erste Steuerschieber 15/3 mit einer Steuerkurve 24 versehen ist, in welche eine auf dem zweiten Steuerschieber 16/3 angeordnete Kulissenrolle 23 ragt.In the housing 10 of the adjustment device are three first Control spool 15/1, 15/2 and 15/3 parallel to each other and in Carriage direction slidably mounted. Your long sides are designed as toothed strips 17 (Fig. 1-3), in which engage stationary sprockets 18 and 19 and a mutual and opposite coupling of neighboring ones first control spool 15/1 - 15/3. The pinion 19 is on the output shaft of a stepper motor attached to the housing 10 20 arranged as the sectional view of FIG. 4th shows. 4 can also be seen from the sectional view of FIG. that the first two spools 15/1 and 15/2 one ball bearing slotted roller 21 or 22 wear that in control curves the second spool protrudes while the first Control slide 15/3 is provided with a control curve 24, in which one arranged on the second control slide 16/3 Slide roller 23 protrudes.

Die Fig. 1 - 3 zeigen das Zusammenwirken der ersten und der zweiten Steuerschieber der Verstellvorrichtung. Die beiden spiegelbildlich schräg zu der Schlittenlaufrichtung ausgerichteten zweiten Steuerschieber 16/1 und 16/2, die jeweils ein Abzugsschloßteil 12 (Fig. 4) tragen, sind in Fig. 1 auf gleicher Höhenstellung und damit auf Kammgleiche dargestellt. In dieser Lage nehmen auch alle drei in die Schlittenlaufrichtung ausgerichteten ersten Steuerschieber 15/1, 15/2 und 15/3 eine symmetrische Mittellage ein. Alle drei Kulissenrollen 21, 22 befinden sich in der mit einer strichpunktierten Linie eingezeichneten Symmetrieebene E des Schloßsystemes, in welcher sich auch die Achsen der beiden Kupplungs- oder Antriebsritzel 18, 19 befinden. Die beiden spiegelbildlich gleich ausgebildeten und die Abzugsschloßteile 12 tragenden zweiten Steuerschieber 16/1 und 16/2 weisen im Abstand der beiden Kulissenrollen 21 und 22 der ersten Steuerschieber 15/1 und 15/2 zwei querverlaufende und nach beiden Seiten dieser zweiten Steuerschieber 16/1 und 16/2 offene und jeweils mit einer Knickstelle 33, 34 versehene, ungleich gestaltete Steuerbahnen 25.1 und 26.1 bzw. 25.2 und 26.2 auf. Beide Steuerbahnen bilden in bezug auf die Schlittenlaufrichtung und damit die Verstellrichtung der ersten Steuerschieber 15/1 und 15/2 schräge Auflaufflächen 27 und 28. Die beiden schrägen Auflaufflächen 27 und 28 überlappen sich in der Schlittenlaufrichtung gesehen nicht. Dies bedeutet bei der spiegelsymmetrischen Anordnung der beiden zweiten Steuerschieber 16/1 und 16/2, daß solange die Kulissenrolle 21 des ersten Steuerschiebers 15/1 auf die Schrägfläche 27 eines der beiden zweiten Steuerschieber 16/1 oder 16/2 aufläuft, die Kulissenrolle 22 des ersten Steuerschiebers 15/2 nicht auf die schräge Auflauffläche 28 des anderen zweiten Steuerschiebers aufläuft.1-3 show the interaction of the first and the second control slide of the adjusting device. The two mirror image obliquely aligned to the direction of slide second spool 16/1 and 16/2, each one Trigger lock part 12 (Fig. 4) are in Fig. 1 on the same Height position and thus shown on the same ridge. In All three take this position in the direction of the sledge aligned first spool 15/1, 15/2 and 15/3 a symmetrical middle position. All three backdrop rollers 21, 22 are in the one drawn with a dash-dotted line Plane of symmetry E of the lock system, in which the axes of the two clutch or drive pinions 18, 19 are located. The two mirror-image trained equally and the trigger lock parts 12 carrying second control slide 16/1 and 16/2 point in the distance between the two backdrop rollers 21 and 22 of the first spool 15/1 and 15/2 two transverse and to both sides of this second spool 16/1 and 16/2 open and each with a kink 33, 34 provided, unevenly designed control tracks 25.1 and 26.1 or 25.2 and 26.2. Both control lanes form in with respect to the direction of the slide and thus the direction of adjustment the first control spool 15/1 and 15/2 inclined ramp surfaces 27 and 28. The two inclined run-up surfaces 27 and 28 overlap as seen in the carriage direction Not. This means with the mirror-symmetrical arrangement of the two second spool 16/1 and 16/2 that long the sliding block 21 of the first spool 15/1 on the Inclined surface 27 of one of the two second control slides 16/1 or 16/2, the sliding block 22 of the first control slide 15/2 not on the sloping ramp surface 28 of the other second spool opens.

Die in dem ersten Steuerschieber 15/3 ausgebildete Steuerkurve 24 für die Kulissenrolle 23 des zweiten Steuerschiebers 16/3 ist in Fig. 1 obwohl verdeckt, mit einer dicken ausgezogenen Linie gekennzeichnet, damit ihre symmetrische Ausbildung erkennbar wird. Sie steuert über die Kulissenrolle 23 den zweiten Steuerschieber 16/3, der in drei jeweils ein Druckschloßteil 13 tragenden Zungen 29 (Fig. 1) endet, in Richtung des in Fig. 1 eingezeichneten Doppelpfeiles 30. Die schräge Verstellbewegung der beiden anderen zweiten Steuerschieber 16/1 und 16/2 ist durch Doppelpfeile 31 angedeutet, während die gegenläufige Längsbewegung der ersten Steuerschieber 15/1 - 15/3 in Fig. 1 durch Pfeile 32 gekennzeichnet ist.The control cam formed in the first control slide 15/3 24 for the sliding block 23 of the second control slide 16/3 is hidden in Fig. 1, with a thick solid Line marked so that their symmetrical formation is recognizable becomes. It controls the second via the link roller 23 Control spool 16/3, each in three a pressure lock part 13 bearing tongues 29 (Fig. 1) ends in the direction of Fig. 1 drawn double arrow 30. The oblique adjustment movement the other two control spools 16/1 and 16/2 is indicated by double arrows 31, while the opposite Longitudinal movement of the first spool 15/1 - 15/3 in Fig. 1 is marked by arrows 32.

Wird bei der Symmetriestellung der Verstellvorrichtung nach Fig. 1 die Welle des Schrittschaltmotors 20 und damit das Ritzel 19 im Gegenuhrzeigersinne bewegt, ergibt sich die aus Fig. 2 ersichtliche gegenläufige Verstellung der ersten Steuerschieber 15/1 - 15/3. Dabei läuft die Kulissenrolle 21 des ersten Steuerschiebers 15/1 auf die schräge Auflauffläche 27 der Steuerbahn 25.2 des zweiten Steuerschiebers 16/2 auf und bewirkt eine schräge Abwärtsbewegung dieses zweiten Steuerschiebers in eine gewünschte Abzugsstellung des zugeordneten Abzugsschloßteiles 12. Der andere und ebenfalls ein Abzugsschloßteil 12 tragende zweite Steuerschieber 16/1 verbleibt in der kammgleichen Stellung, weil die Kulissenrolle 22 des gegenläufig bewegten ersten Steuerschiebers 15/2 die schräge Auflauffläche 28 der Steuerbahn 26.1 des ersten Steuerschiebers 16/1 nicht erreicht hat. Der zweite Steuerschieber 16/3 mit den Druckschloßteilen 13 hat ebenfalls noch keine Verstellbewegung erfahren, da sich seine Kulissenrolle 23 noch in dem geradlinigen Mittelteil der Steuerbahn 24 des ersten Steuerschiebers 15/3 befindet.Will be in the symmetry position of the adjustment device Fig. 1, the shaft of the stepper motor 20 and thus that Pinion 19 moves counterclockwise, it results from Fig. 2 apparent opposite adjustment of the first spool 15/1 - 15/3. The backdrop roller 21 runs first control slide 15/1 on the inclined ramp surface 27 the control path 25.2 of the second spool 16/2 on and causes an oblique downward movement of this second spool in a desired trigger position of the assigned Trigger lock part 12. The other and also a trigger lock part 12 bearing second spool 16/1 remains in the comb-like position because the backdrop roller 22 of the opposite moved first control spool 15/2 the oblique Ramp surface 28 of the control track 26.1 of the first control slide Has not reached 16/1. The second control spool 16/3 with the pressure lock parts 13 also has no adjustment movement experienced because his backdrop role 23 is still in the straight middle part of the control path 24 of the first control slide 15/3 is located.

Erfolgt eine weitere Stellbewegung des Schrittschaltmotors 20 im Gegenuhrzeigersinne seiner Abtriebswelle, gelangt die Verstellvorrichtung in die aus Fig. 3 ersichtliche Relativstellung ihrer Steuerschieber. Der zweite Steuerschieber 16/2 ist in die tiefste Abzugsstellung seines Abzugsschloßteiles 12 abwärts bewegt worden.
