Description

Gegenstand der Erfindung ist eine Schiffchenstickmaschine gemäss Oberbegriff der Patentansprüche 1 und 12.The invention relates to a shuttle embroidery machine according to the preamble of claims 1 and 12.

Schiffchenstickmaschinen sind seit mehr als einem Jahrhundert bekannt und arbeiten nach dem Zweifadensystem, das heisst mit einem Nadelfaden und einem Schiffchenfaden, wobei der Nadelfaden bei jedem Stich mit dem Schiffchenfaden verschlungen wird. Eine vorne mit einem Öhr versehene Nadel transportiert den Nadelfaden durch den Stoff hindurch auf die Hinterseite des Stoffes, wo der Nadelfaden beim Zurückziehen der Nadel eine Schlaufe bildet. Durch diese Schlaufe wird dann das Schiffchen, in welchem der Schiffchenfaden enthalten ist, hindurch geführt. Schiffchenstickmaschinen umfassen eine grosse Anzahl von in einer Reihe angeordneten Stickstellen und dementsprechend viele Nadeln und Schiffchen. Zur Auf- und Ab-Bewegung des Schiffchens auf einer vertikalen, leicht geneigten Lage dient ein Treiberbalken.Shuttle embroidery machines have been known for more than a century and work according to the two-thread system, that is with a needle thread and a shuttle thread, wherein the needle thread is devoured with the shuttle thread with each stitch. An eyelet-fronted needle transports the needle thread through the fabric to the back of the fabric where the needle thread forms a loop as the needle retracts. Through this loop then the boat, in which the shuttle thread is included, passed through. Shuttle embroidery machines comprise a large number of embroidering points arranged in a row and correspondingly many needles and shuttles. Up and down movement of the shuttle on a vertical, slightly inclined position is a driver bar.

Aus der EP 1 595 990 ist eine solche Schiffchenstickmaschine bekannt mit einem durch einen Kurbeltrieb oszillierten Treiberbalken. Mittels des Treiberbalkens, der sich über die gesamte Länge der Maschine erstreckt, wird mit zwei jeder Nadel zugeordneten Treibernägeln die Schiffchen durch die zuvor gebildete Nadelfadenschlaufe und zurück befördert. Mit dem Kurbelantrieb des Treiberbalkens können 600 und mehr Stiche pro Minute erzeugt werden.From the EP 1 595 990 Such a shuttle embroidery machine is known with a driver bar oscillated by a crank drive. By means of the Driver bar, which extends over the entire length of the machine is conveyed with two each needle associated driver nails the shuttle through the previously formed needle thread loop and back. With the crank drive of the driver bar 600 and more stitches per minute can be generated.

Um die Kosten von Stickereien zu senken, werden von Kundenseite Maschinen gefordert, die eine höhere Stichzahl erreichen können. Dies ist zwar mit einem Antrieb gemäss der EP 1 595 990 möglich, jedoch nur auf Kosten von hohem Verschleiss mehrerer Elemente des Antriebs. Durch die hohen Beschleunigungen an den oberen und unteren Umkehrpunkten des Treiberbalkens, mit welchem der untere und der obere Treibernagel das Schiffchen durch die Schlaufe des Nadelfadens führt, werden die Lagerstellen im Kurbelgetriebe so sehr belastet, dass deren Lebensdauer durch Verschleiss verkürzt wird. So kann es vorkommen, dass die Kugeln in den Linearführungen der Treiberbalkenführung den Bewegungen nicht mehr rollend folgen können, sondern in den Führungsbahnen gleiten und in der Folge zu hoher örtlicher übermässiger Abnützung führen. Insbesondere werden auch die Lagerbohrung und die Achse an der Kurbelstange, welche ein Hin-und-her-Gleiten des Treiberbalkens auf seiner schräg zur Senkrechten verlaufenden Bahn ermöglicht, bis an die Grenzen beansprucht. Gemäss der Sonderausführung der DE8436780U1 können Schiffchen in einer mittleren Stellung mittels eines Zwischengetriebes unter Verwendung einer Koppelstange, mittels welcher eine von einer hin- und herdrehenden Schwingwelle angetriebenen Antriebsschiene stillgesetzt werden. Hierzu wird das mittels eines Gleitsteins in einer Kulisse der Schwingwelle geführte Antriebsende der Koppelstange aus einer exzentrischen Lage in eine mit der Achse der Schwingwelle zusammenfallende Lage überführt, wodurch es ermöglicht ist, dass trotz der kontinuierlichen Bewegung der Schwingwelle der Verstellantrieb für den Treiberbalken bewegungslos gehalten wird. Diese Sonderausführung wird nur dann benötigt, wenn auf einer Schiffchenstickmaschine nicht nur Stickereien ausgeführt werden, sondern auch Bohrware durch Einbringen von Löchern in den Stickgrund hergestellt wird.In order to reduce the cost of embroidery, customers are demanding machines that can achieve a higher number of stitches. This is true with a drive according to the EP 1 595 990 possible, but only at the expense of high wear of several elements of the drive. Due to the high accelerations at the upper and lower reversal points of the driver bar, with which the lower and the upper driver nail leads the shuttle through the loop of the needle thread, the bearings in the crank gear are so much burdened that their life is reduced by wear. So it may happen that the balls in the linear guides of the driver bar guide can no longer follow the movements of the rolling, but slide in the guideways and consequently lead to high local excessive wear. In particular, the bearing bore and the axis on the connecting rod, which allows a back-and-forth sliding of the driver bar on its obliquely to the vertical path running, claimed to the limits. According to the special version of the DE8436780U1 can shuttle in a middle position by means of an intermediate gear using a Coupling rod, by means of which a driven by a reciprocating oscillating shaft drive rail are stopped. For this purpose, the guided by means of a sliding block in a backdrop of the oscillating shaft drive end of the coupling rod is transferred from an eccentric position in a coincident with the axis of the oscillating shaft position, whereby it is possible that, despite the continuous movement of the oscillating shaft of the adjusting drive for the driver bar is held motionless , This special version is only required if not only embroideries are carried out on a shuttle embroidery machine, but also drilling material is produced by introducing holes into the embroidery base.

In der CH 703 090 wird ein Antrieb des Treiberbalkens offenbart, mit welchem die Schiebebewegung zwischen der Pleuelstange und dem Treiberbalken vermieden werden soll. Es wird dabei die Pleuelstange mit biegsamen Elementen an deren beiden Enden ausgerüstet, so dass die seitlichen Bewegungen nicht durch ein Gleiten auf einer Welle auf dem Treiberbalken, sondern durch eine elastische Verformung der Pleuelstange aufgenommen werden sollen. Wohl findet bei diesem Stand der Technik keine Schiebebewegung statt, jedoch müssen die Biegekräfte, verursacht durch die Federelemente an der Pleuelstange, bei jedem Hub zweimal überwunden werden. Dies ist nur möglich mit einer höheren Antriebsleistung des Hubantriebs. Weiter neigen elastische Maschinenelemente bei Hubzahlen von mehr als 600 pro Minute dazu, zu den bereits vorhandenen Schwingungen in einer Schiffchenstickmaschine zusätzliche Schwingungen des Treiberbalkens zu erzeugen. Dabei wird nicht nur der Treiberbalken in Schwingung versetzt, sondern auch die Schiffchenbahnen und die darin transportierten Schiffchen werden in Schwingung versetzt. Die durch die elastischen Elemente vermiedenen Schiebebewegungen beziehungsweise der Verschleiss der dort nicht mehr benötigten Elemente verlagert sich somit auf den Verschleiss an der Schiffchenbahn und zu den zum Treiberbalken geneigt zur Vertikalen führenden Linearführungselementen und zu den ohnehin unerwünschten Schwingungen der Schiffchenstickmaschine durch die federelastischen Elemente an den Pleueln.In the CH 703 090 a drive of the driver bar is disclosed, with which the sliding movement between the connecting rod and the driver bar should be avoided. It is doing the connecting rod equipped with flexible elements at both ends, so that the lateral movements are not to be absorbed by a sliding on a shaft on the driver bar, but by an elastic deformation of the connecting rod. Probably no sliding movement takes place in this prior art, but the bending forces caused by the spring elements on the connecting rod, must be overcome twice at each stroke. This is only possible with a higher drive power of the linear actuator. Furthermore, elastic machine elements tend with stroke rates of more than 600 per Minute to generate additional vibrations of the driver bar to the existing vibrations in a shuttle embroidery machine. Not only does the driver bar vibrate, but also the shuttle lanes and the boats they carry are vibrated. The avoided by the elastic elements sliding movements or the wear of the elements no longer needed there is thus shifted to the wear on the shuttle and to the driver bar inclined to the vertical leading linear guide elements and the already undesirable vibrations of the shuttle embroidery machine by the elastic elements on the connecting rods ,

Eine Aufgabe der vorliegenden Erfindung besteht darin, eine Schiffchenstickmaschine zu schaffen, deren Antriebsmittel für den Treiberbalken eine Erhöhung der Stichzahl pro Minute über die bisher erreichbaren Stichzahlen pro Minute ermöglicht und bei der der Verschleiss der Antriebsmittel gegenüber den bisher bekannten Antriebsmitteln wesentlich verringert wird. Eine weitere Aufgabe besteht darin, die Geräuschentwicklung des Antriebs für den Treiberbalken trotz höherer Stichzahl zu reduzieren, einhergehend mit einer Reduktion der erzeugten Schwingungen. Eine weitere Aufgabe der Erfindung besteht darin, Schiebebewegungen in den Antriebsmitteln und am Treiberbalken zu eliminieren und die Linearführungsmittel durch geeignete Elemente zu ersetzen.
Eine weitere Aufgabe der Erfindung besteht darin, die Schiffchenstickmaschine beziehungsweise ein und derselbe Antrieb für den Treiberbalken derart weiterzubilden, dass er sowohl für Stickmaschinen mit Schiffchenbahnen eingesetzt werden kann, welche nicht nur im Gegenuhrzeigersinn geneigt zur Senkrechten angeordnet sind, sondern auch solche, die im Uhrzeigersinn geneigt zur Senkrechten stehen.An object of the present invention is to provide a shuttle embroidery machine, the drive means for the driver bar an increase in the number of stitches per minute on the previously achievable stitch counts per minute and in which the wear of the drive means compared to the previously known drive means is substantially reduced. Another object is to reduce the noise of the drive for the driver bar despite higher stitch count, along with a reduction of the vibrations generated. Another object of the invention is sliding movements in the drive means and on To eliminate driver bar and replace the linear guide means with suitable elements.
Another object of the invention is to further develop the shuttle embroidery machine or one and the same drive for the driver bar so that it can be used both for embroidery machines with Schiffchenbahnen, which are arranged not only counterclockwise inclined to the vertical, but also those in the clockwise direction stand inclined to the vertical.

Diese Aufgaben werden erfindungsgemäss durch eine Schiffchenstickmaschine gemäss den Merkmalen der Patentansprüche 1 und 12 gelöst. Vorteilhafte Lösungen der Aufgaben sind in den abhängigen Ansprüchen umschrieben.These objects are achieved according to the invention by a shuttle embroidery machine according to the features of patent claims 1 and 12. Advantageous solutions of the tasks are described in the dependent claims.

Mit dem erfindungsgemässen Kurbeltrieb kann nicht nur eine höhere Stichzahl erreicht werden, sondern für die geneigt zur Vertikalen verlaufende Verschiebung des Treiberbalkens sind keine Linearführungsmittel in Gestalt von Führungsstangen oder Führungsschienen mehr notwendig. Die Linearbewegung des Treiberbalkens wird durch ein geeignet ausgebildetes Viergelenk erzeugt, welches durch einen Kurbeltrieb angetrieben wird. Die Schiebebewegungen werden durch Drehbewegungen ersetzt, welche bekannterweise geringere Geräuschentwicklungen hervorrufen und mit welchem zudem an den Umkehrpunkten der schräg laufenden Verschiebung des Treiberbalkens wesentlich geringere Beschleunigungs- und Verzögerungskräfte erzeugt werden. Als Folge davon werden auch die Lager wesentlich weniger belastet und ein Gleiten der Wälzkörper in den Lagerbahnen vermieden.With the crank mechanism according to the invention not only a higher number of stitches can be achieved, but for the inclined to the vertical displacement of the driver bar no linear guide means in the form of guide rods or guide rails longer necessary. The linear movement of the driver bar is generated by a suitably designed four-bar linkage, which is driven by a crank drive. The sliding movements are replaced by rotational movements, which are known to cause lower noise and with which also much lower at the reversal points of the oblique current displacement of the driver bar Acceleration and deceleration forces are generated. As a result, the bearings are much less burdened and avoided sliding of the rolling elements in the bearing tracks.

Ein weiterer Vorteil der Erfindung besteht darin, dass ohne Austausch von Maschinenelementen der Antrieb von Schiffchenbahnen mit einem gegenüber der Vertikalen spiegelbildlich angeordneten Winkel verwendbar ist.Another advantage of the invention is that without replacement of machine elements, the drive of Schiffchenbahnen with a respect to the vertical mirror image arranged angle is usable.

Der in Figur 1 dargestellte Stand der Technik entspricht der EP 1 595 990 und deren Elemente und Funktionsweise sind im Text zu Figur 4 der EP 1 595 990 im Einzelnen beschrieben. In dieser Ausführung des Antriebs für einen Treiberbalken ist letzterer auf geneigt zur Vertikalen liegenden Führungen verschiebbar auf Führungsstangen gelagert. Der Neigungswinkel zur Senkrechten beträgt vorzugsweise 15°. Der Hubantrieb für den Treiberbalken mit dem Kurbelgetriebe aus Kurbel und Pleuel erfolgt hingegen in exakt vertikaler Richtung. Um die seitliche Verschiebung des Treiberbalkens während dessen Verschiebung zu kompensieren, ist an diesem eine horizontal verlaufende Welle angeordnet, auf der die Antriebsstange / der Pleuel quer zur Antriebsrichtung verschiebbar gelagert ist, so dass der Treiberbalken in dieser Lagerung relativ zum Pleuel seitlich verschiebbar ist. Diese Schiebebewegung ist bei hohen Drehzahlen einem entsprechend hohen Verschleiss insbesondere in den Umkehrpunkten ausgesetzt. Der Kurbelarm kann Teil einer Wippe oder direkt an einer durchgehenden Königswelle angebracht sein.
In der CH 703 090 wird eine mögliche Lösung zur Behebung des Verschleisses offenbart (Figur 2). Diese vermeidet die Schiebebewegung am Pleuelende, jedoch durch den gefederten Pleuel müssen bei jedem Hub zweimal Biegekräfte überwunden werden, um die Federelemente aus ihrer Ruhestellung zu biegen. Dadurch werden die Schrägführungen, auf denen der Treiberbalken gelagert ist, zusätzlich zu den hohen Reibkräften und noch mehr einem Verschleiss ausgesetzt.The in FIG. 1 illustrated prior art corresponds to the EP 1 595 990 and their elements and functioning are in the text too FIG. 4 of the EP 1 595 990 described in detail. In this embodiment of the drive for a driver bar the latter is slidably mounted on guide rods inclined on inclined to the vertical guides. The angle of inclination to the vertical is preferably 15 °. The lifting drive for the driver bar with the crank mechanism of crank and connecting rod, however, takes place in exactly vertical direction. In order to compensate for the lateral displacement of the driver bar during its displacement, a horizontally extending shaft is arranged on this, on which the drive rod / the connecting rod is mounted transversely to the drive direction, so that the driver bar in this storage relative to the connecting rod laterally displaceable is. This sliding movement is exposed at high speeds a correspondingly high wear, especially in the reversal points. The crank arm may be part of a rocker or mounted directly on a continuous king shaft.
In the CH 703 090 is a possible solution for the removal of the wear revealed ( FIG. 2 ). This avoids the sliding movement at the connecting rod end, but by the spring-loaded connecting rod twice bending forces must be overcome at each stroke to bend the spring elements from its rest position. As a result, the inclined guides on which the driver bar is mounted, in addition to the high frictional forces and even more exposed to wear.

In der erfindungsgemässen Ausführung der Antriebs- und Führungsvorrichtung 1 gemäss den Figuren 3-7 ist wie im Stand der Technik gemäss EP 1 595 990 mit Bezugszeichen 3 eine Lagerstelle (Welle) für einen Kurbelarm 5 bezeichnet. Über dem Kurbelarm 5 erfolgt eine Bewegungsübertragung von der Lagerstelle 3 zu einer Antriebsstange, kurz Pleuel 7 genannt. Im Gegensatz zur bekannten Ausführung gemäss Figur 1 ist das antriebsseitige Ende 7 des Pleuels 7 nicht direkt im abtriebsseitigen Ende 5 des Kurbelarms 5 gelagert. Der Antrieb vom Kurbelarm 5 auf den Pleuel 7 erfolgt über ein erstes Gelenk 9, welches einerseits auf einem Kurbelzapfen 11 und andererseits, um 90° verdreht, am antriebsseitigen Ende 7' des ersten Gelenkes 9 auf einem Pleuelzapfen 13 gelagert ist. Das erste Gelenk 9 stellt also eine spezielle Ausbildung eines Kreuzgelenks dar, welches ermöglicht, dass der Pleuel 7 senkrecht zur Längserstreckung des Treiberbalkens 15 schwenkbar gelagert ist, um die horizontale Verschiebung des Treiberbalkens 15 relativ zum Pleuel 7 aufnehmen zu können. Zudem können auf diese Weise die nicht unerheblichen Wechsellasten optimal übertragen werden. Der Treiberbalken 15 ist in Figur 4 in strichpunktierten Linien nur angedeutet. In den übrigen Figuren ist er der besseren Übersichtlichkeit halber jeweils ganz weggelassen und die Führung- und Antriebvorrichtung 1 in Alleinstellung wiedergegeben. Das obere Ende 7" des Pleuels 7 ist ebenfalls in einem zweiten. Kreuzgelenk 17, das ähnlich dem unteren ersten Gelenk 9 ausgebildet ist, über einen Pleuelzapfen 13 schwenkbar gelagert. Das zweite Gelenk 17 ist auf einem Lagerzapfen 19 schwenkbar. Der Lagerzapfen 19 ist Teil eines Befestigungselements 21, welches die Verbindung zum Treiberbalken 15 herstellt und mit diesem zum Beispiel verschraubt ist.
Am Befestigungselement 21 ist weiter eine Lageraufnahme 23 ausgebildet, an welcher eine erste Schwinge 25 schwenkbar und rechtwinklig zum Lagerzapfen 19 angelenkt ist. Etwa in der Mitte der ersten Schwinge 25 ist eine dritte Schwinge 33 einerseits auf einer Achse A und andererseits auch auf einer Achse C schwenkbar angelenkt. Die Achse C beziehungsweise eine darauf angeordnete Welle ist ortsfest durch eine Basisplatte 28 mit einem am Maschinengestell der Schiffchenstickmaschine befestigten Träger 27 oder direkt mit der Schiffchenstickmaschine verbunden. Das zweite Ende der ersten Schwinge 25 ist über einen Schwingenzapfen 29 mit einer Achse E gelenkig mit dem ersten Ende einer zweiten Schwinge 31 verbunden. Das zweite Ende der zweiten Schwinge 31 ist um eine Achse B schwenkbar gelagert. Die Achse B ist ortsfest auf der Basisplatte 28 angeordnet.In the inventive embodiment of the drive and guide device 1 according to the Figures 3-7 is as in the prior art according to EP 1 595 990 denoted by reference numeral 3 a bearing point (shaft) for a crank arm 5. About the crank arm 5 is a motion transmission from the bearing 3 to a drive rod, called connecting rod 7 shortly. In contrast to the known embodiment according to FIG. 1 the drive-side end 7 of the connecting rod 7 is not mounted directly in the output-side end 5 of the crank arm 5. The drive from the crank arm 5 to the connecting rod 7 via a first joint 9, which on the one hand on a crank pin 11 and on the other hand, rotated by 90 °, is mounted on the drive-side end 7 'of the first joint 9 on a crankpin 13. The first joint 9 So represents a special design of a universal joint, which allows the connecting rod 7 is mounted perpendicular to the longitudinal extent of the driver bar 15 pivotally to accommodate the horizontal displacement of the driver bar 15 relative to the connecting rod 7 can. In addition, the not inconsiderable exchange costs can be optimally transferred in this way. The driver bar 15 is in FIG. 4 indicated in dotted lines only. In the other figures, it is the sake of clarity, each omitted entirely and reproduced the guide and drive device 1 in isolation. The upper end 7 "of the connecting rod 7 is also pivotally mounted in a second universal joint 17, which is similar to the lower first joint 9 via a connecting rod 13. The second joint 17 is pivotable on a bearing pin 19. The bearing pin 19 is part a fastening element 21, which establishes the connection to the driver bar 15 and is screwed thereto, for example.
On the fastening element 21, a bearing receptacle 23 is further formed, to which a first rocker 25 is hinged pivotably and at right angles to the bearing pin 19. Approximately in the middle of the first rocker 25, a third rocker 33 is pivoted on the one hand on an axis A and on the other hand also on an axis C. The axis C or a shaft arranged thereon is fixed by a base plate 28 with a carrier 27 or 27 attached to the machine frame of the shuttle embroidery machine directly connected to the shuttle embroidery machine. The second end of the first rocker 25 is pivotally connected via a pivot pin 29 with an axis E to the first end of a second rocker 31. The second end of the second rocker 31 is pivotally mounted about an axis B. The axis B is fixedly arranged on the base plate 28.

Die drei Schwingen 25, 31 und 33 bilden folglich ein Viergelenk mit den beiden ortsfesten Achsen B und C auf der Basisplatte 28 und den beiden auf Kreisbögen mit unterschiedlichen Radien beweglichen Achsen A und E an der ersten Schwinge 25.The three rockers 25, 31 and 33 thus form a four-bar linkage with the two fixed axes B and C on the base plate 28 and the two axes A and E movable on circular arcs with different radii on the first rocker 25.

In Figur 7 ist die obere Endlage des Treiberbalkens 15 dargestellt. Das dem Schwingenzapfen 29 (Achse E) gegenüberliegende Ende der ersten Schwinge 25 ist an der Lageraufnahme 23 am Befestigungselement 21 am Treiberbalken 15 schwenkbar gelagert und um die dort angeordnete Schwenkachse D schwenkbar.In FIG. 7 the upper end position of the driver bar 15 is shown. The pivot pin 29 (axis E) opposite end of the first rocker 25 is pivotally mounted on the bearing mount 23 on the fastener 21 on the driver bar 15 and pivotable about the pivot axis D arranged there.

In der schematischen Darstellung gemäss Figur 8 sind die drei Schwingen 25, 31 und 33 sowie die Anlenkpunkte der Achse B und C am Träger 27 dargestellt. Das Befestigungselement 21, an welchem der Pleuel 7 (Pleuel 7 schematisch dargestellt) angreift, ist nicht detailliert eingezeichnet, sondern es ist nur durch die Pfeile P angedeutet wie der Bewegungsverlauf des Befestigungselements 21 und folglich des Trägerbalkens 15 verläuft. Der Treiberbalken 15, an welchem das Befestigungselement 1 befestigt ist, ist der guten Übersichtlichkeit halber ebenfalls weggelassen. Nachfolgend wird die Funktionsweise der Führungs- und Antriebsvorrichtungen 1 für den Treiberbalken 15 erläutert. Am Treiberbalken 15 greifen mindestens zwei Führungs- und Antriebsvorrichtungen 1 an und tragen und führen dieses auf einer zur Vertikalen geneigten Bahn. Mit der oszillierenden Vertikalbewegung des Pleuels 7, welcher über das Befestigungselement 21 mit dem Treiberbalken 15 gelenkig verbunden ist, wird der Treiberbalken 15 einerseits in Richtung des Pfeiles P nach oben und nach unten bewegt. Da das Befestigungselement 21 und folglich auch der Treiberbalken 15 gelenkig über die Achse D mit dem ersten Hebel 25 verbunden sind, erfolgt die Antriebsbewegung mit dem Pleuel 7 nicht in der Senkrechten, sondern der Treiberbalken 15 wird von der ersten Schwinge 25, die auch an der zweiten und dritten Schwinge 31,33 angelenkt ist, zusätzlich in horizontaler Richtung H bewegt. Durch die Vertikalbewegung P zwischen dem oberen und dem unteren Umkehrpunkt des Pleuels 7 erfolgt also gleichzeitig eine Verschiebung, das heisst eine vertikale Bewegung und gleichzeitig eine horizontale Bewegung um den Betrag H des Treiberbalkens 15. Die seitliche Verschiebung H des Treiberbalkens 15 zwischen dem unteren und dem oberen Umkehrpunkt des Pleuels 7 bewirkt, dass der Treiberbalken 15 sich auf einer annähernd geraden Linie bewegt, welche zur Vertikalen in einem Winkel a, zum Beispiel 15°, liegt. Der Treiberbalken 15 bewegt sich folglich, da dieser von einer Mehrzahl von nebeneinander längs des Treiberbalkens 15 angeordneter Antriebs- und Führungsvorrichtungen 1 getragen wird ohne fest angeordnete Linear-Führungsmittel, z. B. Schienen, wie sie im Stand der Technik gemäss den Figuren 1 und 2 zwingend notwendig sind, auf der gewünschten spitzwinklig zur Vertikalen liegenden und annähernd geradlinig verlaufenden Bahn geführt. Die Antriebsvorrichtung 1 übernimmt damit nicht nur die Hubbewegung P des Treiberbalkens 15, sondern gleichzeitig und ohne Zuhilfenahme von Linear-Führungsmitteln auch die horizontale Bewegung H des Treiberbalkens 15. Sie eliminiert folglich bei jedem Hub und Stich der Stickmaschine zwei geführte Linearbewegungen gemäss Figur 1 und die spitzwinklig zur Senkrechten erfolgenden Linearführung gemäss Figur 2 und dort die schwingungsrelevanten Biegungen des Pleuels 7.In the schematic representation according to FIG. 8 the three rockers 25, 31 and 33 and the pivot points of the axis B and C on the carrier 27 are shown. The fastening element 21, on which the connecting rod 7 (connecting rod 7 is shown schematically) engages, is not shown in detail, but it is only indicated by the arrows P as the course of movement of the Fastener 21 and consequently of the support beam 15 extends. The driver bar 15, to which the fastener 1 is attached, is also omitted for the sake of clarity. The operation of the guiding and driving devices 1 for the driver bar 15 will be explained below. At the driver bar 15 engage at least two guiding and driving devices 1 and carry and run this on a inclined to the vertical path. With the oscillating vertical movement of the connecting rod 7, which is articulated via the fastening element 21 with the driver bar 15, the driver bar 15 is moved on the one hand in the direction of the arrow P upwards and downwards. Since the fastener 21 and consequently also the driver bar 15 are pivotally connected via the axis D with the first lever 25, the drive movement with the connecting rod 7 is not in the vertical, but the driver bar 15 is from the first rocker 25, which also on the second and third rocker 31,33 is articulated, additionally moved in the horizontal direction H. The vertical movement P between the upper and lower reversal point of the connecting rod 7 thus simultaneously a displacement, that is, a vertical movement and at the same time a horizontal movement by the amount H of the driver bar 15. The lateral displacement H of the driver bar 15 between the lower and the upper reversal point of the connecting rod 7 causes the driver bar 15 on a moves approximately straight line, which lies to the vertical at an angle a, for example 15 °. The driver bar 15 thus moves, since it is supported by a plurality of juxtaposed along the driver bar 15 drive and guide devices 1 without fixedly arranged linear guide means, for. B. rails, as in the prior art according to the Figures 1 and 2 are absolutely necessary, guided on the desired acute angle to the vertical and approximately rectilinear path. The drive device 1 thus assumes not only the lifting movement P of the driver bar 15, but at the same time and without the aid of linear guide means and the horizontal movement H of the driver bar 15. It thus eliminates two guided linear movements according to each stroke and stitch of the embroidery machine FIG. 1 and the linear guide taking place at an acute angle to the vertical FIG. 2 and there the vibration-relevant bends of the connecting rod 7.

Ohne einen Austausch von Elementen der Antriebsvorrichtung 1, kann letztere auch für den Antrieb von Treiberbalken 15 in Schiffchenstickmaschinen eingesetzt werden, welche Schiffchenbahnen aufweisen, die eine Schrägstellung zur Vertikalen aufweisen, die in die entgegengesetzte Richtung -α von den Senkrechten verlaufen. Durch einfaches Schwenken der dritten Schwinge 33 im Gegenuhrzeigersinn und damit auch Schwenken der zweiten Schwinge 31 im Uhrzeigersinn von der in Figur 8 in ausgezogenen Linien dargestellten Lage in die mit gebrochenen Linien dargestellte Lage, kann diese Umstellung einfach vorgenommen werden. Die Antriebsvorrichtung arbeitet folglich mit genau den gleichen Maschinenelementen in beiden Schwenkrichtungen und ermöglicht es dem Hersteller, seine Vorrichtung für beide Arten von Schiffchenführung ohne zusätzliche Austauschelemente und damit ohne zusätzliche Kosten und Lagerhaltung anbieten zu können.Without an exchange of elements of the drive device 1, the latter can also be used for driving drive bar 15 in shuttle embroidery machines, which have Schiffchenbahnen having an inclination to the vertical, which extend in the opposite direction -α from the vertical. By simply pivoting the third rocker 33 in the counterclockwise direction and thus also pivoting the second rocker 31 in Clockwise from the in FIG. 8 shown in solid lines in the position shown with broken lines, this conversion can be easily made. The drive device thus operates with exactly the same machine elements in both pivoting directions and allows the manufacturer to offer his device for both types of boat guidance without additional replacement elements and thus without additional costs and storage.
