Description

Die Erfindung betrifft einen Legebarrenantrieb einer Kettenwirkmaschine mit den Merkmalen des Oberbegriffs des Anspruchs 1.The invention relates to a guide bar drive of a warp knitting machine with the features of the preamble of claim 1.

Ferner betrifft die Erfindung eine Legebarrenanordnung mit mindestens einer Legebarre und einem derartigen Antrieb.The invention also relates to a guide bar arrangement with at least one guide bar and such a drive.

Ein derartiger Legebarrenantrieb und eine derartige Legebarrenanordnung sind beispielsweise aus EP 2 982 788 A1 bekannt. Hier sind mehrere Motoren in Versatzrichtung nebeneinander angeordnet. Die Antriebsstößel sind jeweils als Pleuelstangen ausgebildet, die Ausnehmungen aufweisen, durch die jeweils eine Antriebswelle eines näher an der Legebarre angeordneten Antriebsmotors geführt ist.Such a guide bar drive and such a guide bar arrangement are, for example, from EP 2 982 788 A1 known. Several motors are arranged next to one another in the offset direction. The drive tappets are each designed as connecting rods which have recesses through which a drive shaft of a drive motor arranged closer to the guide bar is guided.

Ein weiterer Legebarrenantrieb ist aus EP 1 013 812 A1 bekannt. Die Welle eines Motors ist mit einer Kurbelstange verbunden.Another guide bar drive is off EP 1 013 812 A1 known. The shaft of a motor is connected to a connecting rod.

CN 203113042 U zeigt eine Häkelmaschine mit einer Barre, die über einen rotierenden Hebel und eine Pleuelstange angetrieben ist. CN 203113042 U shows a crochet machine with a bar that is driven by a rotating lever and a connecting rod.

Im Betrieb einer Kettenwirkmaschine müssen Legenadeln, die Fäden einer Fadenschar führen, relativ zu Arbeits- oder Wirknadeln geführt werden, damit die Fäden der Fadenschar Maschen bilden können. Hierzu muss die Legebarre in eine so genannte Versatzrichtung bewegt werden, also parallel zu ihrer Längserstreckung. Die Versatzbewegung wird durch den Legebarrenantrieb bewirkt.When a warp knitting machine is in operation, needles that guide the threads of a group of threads must be guided relative to working or knitting needles so that the threads of the group of threads can form stitches. For this purpose, the guide bar must be moved in a so-called offset direction, that is, parallel to its longitudinal extension. The offset movement is caused by the guide bar drive.

In den letzten Jahren ist man vermehrt dazu übergegangen, eine Legebarre direkt durch eine Motoranordnung anzutreiben, die einen Elektromotor aufweist. Der Elektromotor dreht dabei eine Gewindespindel, auf der eine Kugelgewindemutter angeordnet ist. Die Gewindespindel erstreckt sich parallel zur Längserstreckung der Legebarre. Wenn sich die Gewindespindel dreht, dann wird die Kugelgewindemutter auf der Gewindespindel in Versatzrichtung, also parallel zur Längserstreckung der Legebarre bewegt. Ein Antriebsstößel wird von der Kugelgewindemutter zur Legebarre hin bewegt und verlagert dadurch auch die Legebarre. Die Rückbewegung der Legebarre erfolgt über eine Rückzugsfederanordnung.In recent years there has been an increasing trend towards driving a guide bar directly by a motor arrangement which has an electric motor. The electric motor rotates a threaded spindle on which a ball screw nut is arranged. The threaded spindle extends parallel to the longitudinal extension of the guide bar. When the threaded spindle rotates, the ball screw nut on the threaded spindle is moved in the offset direction, that is, parallel to the longitudinal extension of the guide bar. A drive ram is moved by the ball screw nut towards the guide bar and thereby also displaces the guide bar. The return movement of the guide bar takes place via a return spring arrangement.

Mit einem derartigen Legebarrenantrieb lässt sich die Bewegung einer Legebarre zwar sehr genau steuern. Eine Änderung des Bewegungsmusters der Legebarre ist ebenfalls leicht durchführbar. Allerdings ist der mechanische Aufwand mit einem Getriebe, das eine Gewindespindel und eine Kugelgewindemutter aufweist, relativ groß.With such a guide bar drive, the movement of a guide bar can be controlled very precisely. A change in the movement pattern of the guide bar is also easy to carry out. However, the mechanical complexity with a gearbox that has a threaded spindle and a ball screw nut is relatively large.

DE 295 16 290 U1 zeigt eine Multibar-Kettenwirkmaschine mit Servoantrieb für die Legebarren. Der Servoantrieb weist eine Vielzahl von Motoren auf, die in Versatzrichtung hintereinander angeordnet sind. Die Motoren können beispielsweise über eine Ritzel-Zahnstangen-Verbindung auf die Legebarren wirken. Eine andere Möglichkeit besteht darin, ein Übertragungsglied als Winkelhebel auszubilden. DE 295 16 290 U1 shows a multibar warp knitting machine with servo drive for the guide bars. The servo drive has a large number of motors which are arranged one behind the other in the offset direction. The motors can act on the guide bars, for example, via a rack and pinion connection. Another possibility is to design a transmission element as an angle lever.

DE 199 63 990 A1 zeigt eine Kettenwirkmaschine mit Mustereinrichtung, die eine Anzahl von Musterrädern aufweist, die auf einer gemeinsamen Musterradwelle angeordnet sind und gemeinsam durch einen Elektromotor angetrieben werden. Tastrollen liegen unter dem Einfluss einer Feder am Umfang der Musterräder an und übertragen über eine Stange eine hin- und hergehende Versatzbewegung auf eine Legebarre. DE 199 63 990 A1 shows a warp knitting machine with a pattern device, which has a number of pattern wheels which are arranged on a common pattern wheel shaft and are jointly driven by an electric motor. Under the influence of a spring, feeler rollers rest against the circumference of the sample wheels and transfer a reciprocating offset movement to a guide bar via a rod.

Der Erfindung liegt die Aufgabe zugrunde, eine Legebarre mit geringem Aufwand individuell in Versatzrichtung ansteuern zu können.The invention is based on the object of being able to individually control a guide bar in the offset direction with little effort.

Diese Aufgabe wird bei einem Legebarrenantrieb der eingangs genannten Art mit den Merkmalen des Anspruchs 1 gelöst.In the case of a guide bar drive of the type mentioned at the outset, this object is achieved with the features of claim 1.

Der Antriebsstößel wirkt dann als eine Art Pleuelstange, die eine Rotationsbewegung des Abtriebselements der Motoranordnung in eine translatorische Bewegung der Legebarre umsetzt. Der translatorische Anteil der Bewegung des Antriebsstößels kann dann auf die Legebarre übertragen werden. Die Umsetzung der Rotationsbewegung in eine Translationsbewegung lässt sich mit einem relativ geringen Aufwand erreichen. Die Motoranordnung weist vorzugsweise einen Elektromotor auf, der sich mit einer hohen Genauigkeit ansteuern lässt, beispielsweise einen Schrittmotor oder einen bürstenlosen Gleichstrommotor. Damit ist eine genaue Steuerung der Bewegung der Legebarre möglich.The drive tappet then acts as a type of connecting rod which converts a rotational movement of the output element of the motor arrangement into a translational movement of the guide bar. The translational component of the movement of the drive ram can then be transferred to the guide bar. The conversion of the rotational movement into a translational movement can be achieved with relatively little effort. The motor arrangement preferably has an electric motor which can be controlled with a high degree of accuracy, for example a stepping motor or a brushless direct current motor. This enables precise control of the movement of the guide bar.

Die Wirkverbindung weist einen exzentrisch an dem Abtriebselement angeordneten Zapfen auf, der in ein Auge an dem Antriebsstößel eingreift. Es ergibt sich damit eine formschlüssige Verbindung zwischen dem Abtriebselement und dem Antriebsstößel, durch die bei einer Rotationsbewegung des Abtriebselements eine translatorische Bewegung des Antriebsstößels in beide Richtungen bewirkt wird.The operative connection has a pin which is arranged eccentrically on the output element and which engages in an eye on the drive tappet. This results in a form-fitting connection between the output element and the drive tappet, through which, during a rotational movement of the Output element causes a translational movement of the drive plunger in both directions.

Zwischen dem Zapfen und dem Auge ist ein Tonnenlager angeordnet. Das Tonnenlager ist ein Wälzlager mit ballig ausgebildeten Wälzkörpern, das in der Lage ist, Fluchtungsfehler zwischen der Rotationsachse und einer Achse des Zapfens auszugleichen. Der Zapfen und die Rotationsachse müssen also nicht mehr exakt parallel zueinander angeordnet sein, was die Montage und die Einstellung des Legebarrenantriebs erleichtert.A barrel bearing is arranged between the pin and the eye. The barrel bearing is a rolling bearing with spherical rolling elements that is able to compensate for misalignments between the axis of rotation and an axis of the journal. The pin and the axis of rotation therefore no longer have to be arranged exactly parallel to one another, which simplifies the assembly and adjustment of the guide bar drive.

Vorzugsweise ist die Rotationsachse senkrecht zur Bewegungsrichtung des Antriebsstößels ausgerichtet. Damit wird die Belastung für die Wirkverbindung zwischen dem Abtriebselement und dem Antriebsstößel klein gehalten. Darüber hinaus kann man die Motoranordnung senkrecht zur Versatzrichtung anordnen, wobei hier in der Regel ein ausreichender Bauraum zur Verfügung steht.The axis of rotation is preferably aligned perpendicular to the direction of movement of the drive plunger. This keeps the load on the operative connection between the output element and the drive tappet small. In addition, the motor arrangement can be arranged perpendicular to the direction of offset, with sufficient installation space generally being available here.

Bevorzugterweise weist das Abtriebselement eine Bewegungsbegrenzungseinrichtung auf, die eine Rotation des Abtriebselements auf einen Bewegungsbereich von ± 30° gegenüber einer Neutralstellung begrenzt. Das Abtriebselement wird also gegenüber der Neutralstellung maximal um 30° in beide Richtungen gedreht. Bei einem derartig kleinen Rotationswinkel ändert sich die den Antriebsstößel aufweisende Geometrie nur in einem akzeptablen Maß, d.h. es ergibt sich praktisch nur eine Bewegungskomponente in Versatzrichtung. Eine Bewegungskomponente quer zur Versatzrichtung ist vernachlässigbar. Die Bewegungsbegrenzungseinrichtung kann mechanisch ausgebildet sein. Es ist aber von Vorteil, wenn die Bewegungsbegrenzungseinrichtung in einer Steuerung der Motoranordnung enthalten ist.The output element preferably has a movement limiting device which limits a rotation of the output element to a movement range of ± 30 ° with respect to a neutral position. The output element is therefore rotated a maximum of 30 ° in both directions with respect to the neutral position. With such a small angle of rotation, the geometry having the drive plunger changes only to an acceptable extent, ie there is practically only one movement component in the offset direction. A component of movement transverse to the direction of offset is negligible. The movement limiting device can be designed mechanically. However, it is advantageous if the movement limiting device is contained in a control of the motor arrangement.

Bevorzugterweise ist das Abtriebselement durch ein Lagergehäuse geführt, an dessen einem Ende die Motoranordnung befestigt und an dessen anderem Ende ein Lager für das Abtriebselement angeordnet ist. Dadurch werden Belastungen für Motorlager, d.h. ein Lager für das Abtriebselement innerhalb des Motors, klein gehalten. Durch eine entsprechende Ausgestaltung des Lagergehäuses lassen sich Schwingungserscheinungen klein halten.The output element is preferably guided through a bearing housing, at one end of which the motor arrangement is fastened and at the other end of which a bearing for the output element is arranged. This keeps the loads on the motor bearings, i.e. a bearing for the output element inside the motor, low. Vibration phenomena can be kept small by a corresponding design of the bearing housing.

In einer vorteilhaften Ausgestaltung ist vorgesehen, dass der Antriebsstößel eine Verdrehsicherung aufweist. Die Verdrehsicherung stellt sicher, dass sich der Antriebsstößel nicht um seine Längsachse drehen kann, seine Ausrichtung zum Abtriebselement also beibehält. Damit werden Belastungen für das Lager klein gehalten.In an advantageous embodiment, it is provided that the drive tappet has an anti-twist device. The anti-rotation device ensures that the drive tappet cannot rotate about its longitudinal axis, that is, that it maintains its alignment with the output element. This keeps the loads on the bearing low.

Vorteilhafterweise weist der Antriebsstößel einen Biegefederabschnitt auf. Der Biegefederabschnitt kann beispielsweise durch einen Abschnitt gebildet sein, der gegenüber dem verbleibenden Rest des Antriebsstößels eine verringerte Abmessung in die Richtung aufweist, in der Biegungen zugelassen werden sollen. Die Bewegung des Abtriebselements ist, wie oben ausgeführt, eine Art Pleuelbewegung. Damit ergibt sich bei dem Antriebsstößel keine reine Translation, sondern die Bewegung enthält auch noch einen kleinen Bewegungsanteil in Querrichtung. Diese Bewegung in Querrichtung kann in dem Biegefederabschnitt aufgenommen werden. Der Biegefederabschnitt ermöglicht die erforderte Nachgiebigkeit in Querrichtung.The drive tappet advantageously has a spiral spring section. The spiral spring section can be formed, for example, by a section which, compared to the remainder of the drive plunger, has a reduced dimension in the direction in which bends are to be permitted. As explained above, the movement of the output element is a type of connecting rod movement. This results in no pure translation in the drive tappet, but the movement also contains a small amount of movement in the transverse direction. This movement in The transverse direction can be accommodated in the spiral spring section. The spiral spring section enables the required flexibility in the transverse direction.

Die Erfindung wird auch durch eine Legebarrenanordnung gelöst, die mindestens eine Legebarre aufweist, die einen Legebarrenantrieb aufweist, wie er oben beschrieben worden ist.The invention is also achieved by a guide bar arrangement which has at least one guide bar which has a guide bar drive, as has been described above.

Mit einem derartigen Legebarrenantrieb lässt sich die Bewegung der Legebarre in Versatzrichtung sehr genau steuern, ohne den mechanischen Aufwand hierfür unverhältnismäßig groß machen zu müssen.With such a guide bar drive, the movement of the guide bar in the offset direction can be controlled very precisely without having to make the mechanical effort for this disproportionately large.

Vorzugsweise sind die Legebarre und das Abtriebselement in einer Zug- und Druckkraft übertragenden Weise miteinander verbunden. Das Abtriebselement sorgt also nicht nur dafür, dass die Legebarre in Versatzrichtung in eine Richtung geschoben wird. Das Abtriebselement kann auch dafür sorgen, dass die Legebarre in die entgegengesetzte Richtung gezogen wird. Damit kann man auf eine Rückzugfederanordnung verzichten.The guide bar and the driven element are preferably connected to one another in a manner that transmits tensile and compressive force. The output element therefore not only ensures that the guide bar is pushed in one direction in the offset direction. The output element can also ensure that the guide bar is pulled in the opposite direction. This means that a return spring arrangement can be dispensed with.

Vorzugsweise ist zwischen der Legebarre und dem Abtriebselement eine Längeneinstelleinrichtung vorgesehen. Mit einer derartigen Längeneinstelleinrichtung kann man eine Null- oder Neutralstellung der Legebarre an eine Null- oder Neutralstellung der Motoranordnung anpassen.A length adjustment device is preferably provided between the guide bar and the driven element. With such a length adjustment device, a zero or neutral position of the guide bar can be adapted to a zero or neutral position of the motor arrangement.

Vorzugsweise ist die Längeneinstelleinrichtung an einem Ende des Antriebsstößels angeordnet, das der Legebarre benachbart ist. Die Längeneinstelleinrichtung kann hier auch unmittelbar an der Legebarre angeordnet sein, so dass sie bei einer Demontage des Antriebsstößels an der Legebarre verbleiben kann.The length adjustment device is preferably arranged at one end of the drive ram which is adjacent to the guide bar. The length adjustment device can here also be arranged directly on the guide bar so that it can remain on the guide bar when the drive plunger is dismantled.

In einer bevorzugten Ausgestaltung weist die Längeneinstelleinrichtung eine Exzenterbuchse auf. Wenn die Exzenterbuchse verdreht wird, kann sie die Länge einer Wirkverbindung zwischen dem Abtriebselement und der Barre verändern. Die Exzenterbuchse kann beispielsweise klemmend festgehalten werden, so dass nach dem Einstellen eine Änderung nur dann möglich ist, wenn die Klemmung gelöst wird.In a preferred embodiment, the length adjustment device has an eccentric bushing. If the eccentric bushing is twisted, it can die Change the length of an operative connection between the output element and the bar. The eccentric bushing can, for example, be held in a clamping manner, so that after setting a change is only possible if the clamping is released.

Vorzugsweise sind mehrere Legebarren vorgesehen, wobei jede Legebarre einen Legebarrenantrieb aufweist und die Rotationsachsen von mindestens zwei Legebarrenantrieben unterschiedliche Ausrichtungen aufweisen. Dadurch lässt sich ein Bauraum optimal ausnutzen.A plurality of guide bars are preferably provided, each guide bar having a guide bar drive and the axes of rotation of at least two guide bar drives having different orientations. As a result, an installation space can be optimally used.

Die Erfindung wird im Folgenden anhand eines bevorzugten Ausführungsbeispiels in Verbindung mit der Zeichnung beschrieben. Hierin zeigen:

Eine Legebarrenanordnung 1 weist mehrere Legebarren 2 auf, die in eine Versatzrichtung, die durch einen Doppelpfeil 3 dargestellt ist, hin und her bewegt werden sollen. Jede Legebarre 2 trägt eine Anzahl von Fadenführern 4, die beispielsweise als Legenadeln oder als Lochnadeln ausgebildet sein können.A guide bar arrangement 1 has a plurality of guide bars 2 which are reciprocated in an offset direction, which is represented by a double arrow 3 should be moved. Each guide bar 2 carries a number of thread guides 4, which can be designed, for example, as guide needles or as perforated needles.

Jede Legebarre ist über einen Antriebsstößel 5 mit einem Legebarrenantrieb 6 verbunden. Im Ausführungsbeispiel der Fig. 1 weist der Antriebsstößel 5 eine Längeneinstelleinrichtung 7 auf, mit der die Länge des Antriebsstößels 5 in gewissen Grenzen an einen Abstand zwischen der Legebarre 2 und dem Legebarrenantrieb 6, jeweils in der Neutralstellung dieser beiden Elemente, angepasst werden kann.Each guide bar is connected to a guide bar drive 6 via a drive plunger 5. In the embodiment of Fig. 1 the drive ram 5 has a length adjustment device 7 with which the length of the drive ram 5 can be adjusted within certain limits to a distance between the guide bar 2 and the guide bar drive 6, each in the neutral position of these two elements.

Es ist jedoch von Vorteil, wenn die Längeneinstelleinrichtung 7 im Bereich der Legebarre 2 angeordnet ist und vorzugsweise mit der Legebarre 2 verbunden ist. Im Grunde muss die Längeneinstelleinrichtung 7 nur geeignet sein, an irgendeiner Stelle in die Verbindung zwischen dem Legebarrenantrieb 6 und der Legebarre 2 einzugreifen, um die Länge, wie gewünscht, zu verstellen.However, it is advantageous if the length adjustment device 7 is arranged in the region of the guide bar 2 and is preferably connected to the guide bar 2. Basically, the length adjustment device 7 only has to be suitable for engaging at any point in the connection between the guide bar drive 6 and the guide bar 2 in order to adjust the length as desired.

Die Längeneinstellenrichtung kann auch in zwei oder mehr Abschnitte unterteilt sein, wobei ein Abschnitt für eine Grobeinstellung und ein Abschnitt für eine Feineinstellung verwendet wird. Eine Ausbildung mit zwei Möglichkeiten der Längeneinstellung wird in Fig. 4 weiter unten erläutert.The length adjustment direction may also be divided into two or more sections, one section being used for coarse adjustment and one section being used for fine adjustment. Training with two options for length adjustment is provided in Fig. 4 explained below.

Der Antriebsstößel 5 ist so mit der Legebarre 2 und mit dem Legebarrenantrieb 6 verbunden, dass er sowohl Zugkräfte als auch Druckkräfte von dem Legebarrenantrieb 6 auf die Legebarre 2 übertragen kann. Die Legebarre 2 wird also nicht nur vom Legebarrenantrieb 6 weggeschoben, sondern sie wird für eine Bewegung in die entgegengesetzte Richtung auch wieder vom Legebarrenantrieb 6 gezogen.The drive ram 5 is connected to the guide bar 2 and to the guide bar drive 6 in such a way that it can transmit both tensile forces and compressive forces from the guide bar drive 6 to the guide bar 2. The guide bar 2 is therefore not only pushed away from the guide bar drive 6, but it is also pulled again by the guide bar drive 6 for a movement in the opposite direction.

Der Legebarrenantrieb 6 ist in Fig. 2 und 3 näher dargestellt. Der Legebarrenantrieb weist eine Motoranordnung 8 auf, die einen elektrischen Motor 9 und eine Steuerung 10 aufweist. Die Steuerung 10 setzt beispielsweise Steuersignale, die von einer Steuerung der Kettenwirkmaschine kommen, um eine mustermäßige Bewegung der Legebarre zu steuern, in Antriebsbefehle für den elektrischen Motor 9 um. Der elektrische Motor 9 kann beispielsweise als Schrittmotor oder als bürstenloser Gleichstrommotor ausgebildet sein.The guide bar drive 6 is in Figs. 2 and 3 shown in more detail. The guide bar drive has a motor arrangement 8 which has an electric motor 9 and a controller 10. The controller 10 converts, for example, control signals that come from a controller of the warp knitting machine in order to control a pattern-wise movement of the guide bar into drive commands for the electric motor 9. The electric motor 9 can be designed, for example, as a stepper motor or as a brushless direct current motor.

Die Motoranordnung 8 ist an einer Stirnseite eines Lagergehäuses 11 befestigt. Die Motoranordnung weist ein Abtriebselement 12 in Form einer Welle auf. Die Welle kann beispielsweise die Rotorwellen des Motors 9 sein. Es ist aber auch möglich, das Abtriebselement 12 über eine Kupplung 13 mit der Rotorwelle zu verbinden. In jedem Fall ist das Abtriebselement 12 rotatorisch antreibbar.The motor arrangement 8 is fastened to an end face of a bearing housing 11. The motor arrangement has an output element 12 in the form of a shaft. The shaft can be the rotor shafts of the motor 9, for example. However, it is also possible to connect the output element 12 to the rotor shaft via a coupling 13. In any case, the output element 12 can be driven in rotation.

Allerdings ist der Drehwinkel, durch den sich das Abtriebselement 12 drehen kann, auf einen relativ kleinen Winkelbereich begrenzt. Dieser Winkelbereich beträgt ± 30° um eine Neutralstellung. Die hierfür vorgesehene Bewegungsbegrenzungseinrichtung ist vorzugsweise Teil der Steuereinrichtung 10.However, the angle of rotation through which the output element 12 can rotate is limited to a relatively small angular range. This angular range is ± 30 ° around a neutral position. The movement limiting device provided for this is preferably part of the control device 10.

Das Abtriebselement 12 ist am Lagergehäuse 11 gelagert und zwar in einem Lager 14, das in einer von der Motoranordnung 8 abgewandten Stirnseite 15 des Lagergehäuses 11 angeordnet ist. Das Abtriebselement 12 kann das Lager 14 durchragen.The output element 12 is mounted on the bearing housing 11, specifically in a bearing 14 which is arranged in an end face 15 of the bearing housing 11 facing away from the motor arrangement 8. The output element 12 can protrude through the bearing 14.

Das Abtriebselement 12 weist auf seiner aus dem Lagergehäuse 11 herausweisenden Seite einen exzentrisch gelagerten Zapfen 16 auf, der in ein Auge 17 an dem Antriebsstößel 5 eingreift. Zwischen dem Zapfen 16 und dem Auge 17 ist ein Tonnenlager 18 angeordnet, das in gewissen Grenzen eine Neigung zwischen dem Auge 17 und dem Zapfen 16 zulässt, mit anderen Worten für den Ausgleich von Fluchtungsfehlern verwendet werden kann.On its side facing out of the bearing housing 11, the output element 12 has an eccentrically mounted pin 16 which engages in an eye 17 on the drive tappet 5. Between the pin 16 and the eye 17, a barrel bearing 18 is arranged, which within certain limits allows an inclination between the eye 17 and the pin 16, in other words can be used to compensate for misalignments.

Wenn die Motoranordnung 8 in Betrieb gesetzt wird und das Abtriebselement 12 hin und her dreht, dann bewirkt der durch den Zapfen 16 und das Auge 17 gebildete Übertragungsmechanismus eine Umsetzung der rotatorischen Bewegung des Abtriebselements 12 in eine translatorische Bewegung des Antriebsstößels 5. Aufgrund des relativ kleinen Drehwinkels des Abtriebselements 12 behält der Antriebsstößel 5 seine Ausrichtung, die er in der Neutralstellung eingenommen hat, bei. Diese Ausrichtung verläuft im Wesentlichen parallel zur Versatzrichtung 3. Eine relativ kleine Winkelveränderung des Antriebsstößels 5 wird sich zwar nicht vermeiden lassen. Diese Winkeländerung ist jedoch so klein, dass sie die Bewegung der Legebarre 2 in Versatzrichtung praktisch nicht negativ beeinflusst.When the motor arrangement 8 is put into operation and the output element 12 rotates back and forth, the transmission mechanism formed by the pin 16 and the eye 17 converts the rotational movement of the output element 12 into a translational movement of the drive tappet 5. Due to the relatively small Angle of rotation of the output element 12, the drive tappet 5 maintains its orientation that it assumed in the neutral position. This alignment runs essentially parallel to the offset direction 3. A relatively small change in the angle of the drive plunger 5 cannot be avoided. However, this change in angle is so small that it practically does not negatively affect the movement of the guide bar 2 in the offset direction.

Wie man in Fig. 1 erkennen kann, kann die Legebarrenanordnung 1 auch mehrere Legebarren 2 aufweisen, wobei jeder Legebarre 2 ein eigener Legebarrenantrieb 6 zugeordnet ist. Wie man in Fig. 1 erkennen kann, haben die einzelnen Legebarren 2 unterschiedliche Ausrichtungen im Raum. So kann beispielsweise ein Legebarrenantrieb 6 eine Rotationsachse aufweisen, die in Schwerkraftrichtung verläuft, während eine zweiter Legebarrenantrieb 6 eine Rotationsachse aufweist, die unter einem Winkel von 45° zur Schwerkraftrichtung verläuft und ein dritter Legebarrenantrieb 6 kann eine Rotationsachse aufweisen, die senkrecht zur Schwerkraftrichtung verläuft. Dadurch ist es möglich, den zur Verfügung stehenden Bauraum relativ gut auszunutzen.How to get in Fig. 1 As can be seen, the guide bar arrangement 1 can also have several guide bars 2, each guide bar 2 being assigned its own guide bar drive 6. How to get in Fig. 1 can see, the individual guide bars have 2 different orientations in space. For example, a guide bar drive 6 can have an axis of rotation that runs in the direction of gravity, while a second guide bar drive 6 has an axis of rotation that runs at an angle of 45 ° to the direction of gravity and a third guide bar drive 6 can have an axis of rotation that runs perpendicular to the direction of gravity. This makes it possible to make relatively good use of the available installation space.

Bei einer größeren Anzahl von Legebarren kann man die einzelnen Legebarrenantriebe 6 in Versatzrichtung auch versetzt zueinander anordnen.With a larger number of guide bars, the individual guide bar drives 6 can also be arranged offset to one another in the offset direction.

In diesem Fall sind lediglich unterschiedlich lange Antriebsstößel 5 erforderlich.In this case, only drive tappets 5 of different lengths are required.

Fig. 4 zeigt eine abgewandelte Ausgestaltung des Antriebsstößels 5. Der Antriebsstößel 5 weist hier eine Klemmbuchse 19 mit zwei Klemmbereichen 20, 21 auf. Mit dem Klemmbereich 20 wird die Klemmbuchse 19 am Antriebsstößel 5 befestigt, während sie mit dem Klemmbereich 21 am Auge 17 befestigt wird, das zu diesem Zweck einen Fortsatz 22 aufweist. Fig. 4 shows a modified embodiment of the drive tappet 5. The drive tappet 5 here has a clamping bush 19 with two clamping areas 20, 21. The clamping bush 19 is fastened to the drive plunger 5 with the clamping area 20, while it is fastened with the clamping area 21 on the eye 17, which has an extension 22 for this purpose.

Die Klemmbuchse 19 weist eine axial verlaufende Nut 23 auf. Der Fortsatz 22 kann eine entsprechende Passfeder aufweisen, so dass die Nut 23 mit der Passfeder eine Verdrehsicherung bildet, mit der dafür gesorgt wird, dass sich der Antriebsstößel 5 gegenüber dem Auge 17 nicht um seine Längsachse verdrehen kann.The clamping sleeve 19 has an axially extending groove 23. The extension 22 can have a corresponding feather key, so that the groove 23 with the feather key forms an anti-twist device with which it is ensured that the drive plunger 5 cannot turn around its longitudinal axis with respect to the eye 17.

Weiterhin weist der Antriebsstößel 5 beispielsweise an seinem der Legebarre 2 benachbarten Ende einen Biegefederabschnitt 24 auf. Da die Bewegung des Antriebsstößels 5 aufgrund des "Pleuelantriebs" mit dem Auge 17 keine rein translatorische Bewegung ist, sondern eine kleine Komponente quer zur Längserstreckung des Antriebsstößels 5 aufweist, kann man den Biegefederabschnitt 24 verwenden, um eine Nachgiebigkeit in Querrichtung zu erzeugen. Diese Nachgiebigkeit verhindert die Entstehung größerer Kräfte. Der Biegefederabschnitt 24 kann auf einfache Weise dadurch gebildet sein, dass der Antriebsstößel 5 in diesem Bereich abgeflacht ist.Furthermore, the drive plunger 5 has, for example, a spiral spring section 24 at its end adjacent to the guide bar 2. Since the movement of the drive tappet 5 due to the "connecting rod drive" with the eye 17 is not a purely translational movement, but rather has a small component transverse to the longitudinal extension of the drive tappet 5, the spiral spring section 24 can be used to generate flexibility in the transverse direction. This resilience prevents the creation of greater forces. The spiral spring section 24 can be formed in a simple manner in that the drive tappet 5 is flattened in this area.

Fig. 5 zeigt weiterhin eine Ausführungsform einer Feineinstellung. Fig. 5 further shows an embodiment of a fine adjustment.

Die Legebarre 2 weist an ihrem dem Antriebsstößel 5 zugewandten Ende einen Schlitz 25 auf, in den der Biegefederabschnitt 24 eintritt. Der Biegefederabschnitt 24 weist eine einseitige offene Öffnung 26 auf. In die Öffnung 26 tritt ein Zapfen 27 ein, der an einem Exzenter 28 ausgebildet ist, der in einer entsprechenden Bohrung 29 der Legebarre 2 drehbar gelagert ist. Durch Verdrehen des Exzenters 28 lässt sich in gewissen Grenzen der Zapfen 27 in Längserstreckung des Antriebsstößels 5 verlagern, um so die wirksame Länge zwischen dem Abtriebselement 12 und der Legebarre 2 zu verändern. Eine Klemmschraube 30 ist vorgesehen, um die Winkelausrichtung des Exzenters 28 nach erfolgter Einstellung festzuhalten. Ein Verdrehen des Exzenters 28 ist erst nach Lösen der Klemmschraube 30 möglich.The guide bar 2 has at its end facing the drive plunger 5 a slot 25 into which the spiral spring section 24 enters. The spiral spring section 24 has an opening 26 that is open on one side. A pin 27, which is formed on an eccentric 28, enters the opening 26, which is rotatably mounted in a corresponding bore 29 of the guide bar 2. By turning the eccentric 28, the pin 27 can be displaced in the longitudinal extension of the drive plunger 5 within certain limits in order to change the effective length between the output element 12 and the guide bar 2. A clamping screw 30 is provided to hold the angular alignment of the eccentric 28 after the adjustment has been made. The eccentric 28 can only be rotated after the clamping screw 30 has been loosened.

Die Legebarre weist darüber hinaus eine Durchgangsbohrung 31 auf. Der Biegefederabschnitt 24 weist eine entsprechende Bohrung 32 auf, die allerdings einen größeren Durchmesser aufweist. Nach erfolgter Einstellung kann man dann eine Klemmschraube durch die Durchgangsbohrungen 31, 32 führen, um den Biegefederabschnitt 24 zusätzlich durch eine Klemmung an der Barre 2 zu fixieren.The guide bar also has a through hole 31. The spiral spring section 24 has a corresponding bore 32, which, however, has a larger diameter. After the adjustment has been made, a clamping screw can then be guided through the through bores 31, 32 in order to additionally fix the spiral spring section 24 to the bar 2 by clamping.
