Abstract

The warp knitter has at least one bar which can be shifted along a given path, such as a laying bar with guide needles. One controlled motor acts on one end of the bar and a return mechanism acts on the other end as a second controlled motor. A control unit (18) sets the first motor (4 or 7) to shift the guide bar (1) in one racking direction with a directional force (P1 or P2) and the other motor (7 or 4) to move the guide bar (1) in the opposite direction (P2 or P1). The motors (4,7) apply the directional tension forces (S1,S2) on the bar movement lines. The bar is a strip (1). The control (18) has a proportional-integral (PI) control unit (11) to control the first or second motor (4,7) and a control (20) which reacts to the force component controls of the other motor (7,4). The control (18) passes the actual and nominal bar position values to the PI control (11) as absolute values. The scale (15) of the actual value transmitter is attached to the bar (1). The total setting path movement length of the bar (1) is at least 150 mm. The motors (4,7) are linear motors or rotary motors. The strip acting as the guide bar carries yarn guides, or it is perforated with yarn guide holes.

Description

Die Erfindung bezieht sich auf eine Kettenwirkmaschine mit mindestens einer um vorbestimmte Wege versetzbaren Barre, wie Legebarre, einem ersten steuerbaren Motor, der an einem Barrenende angreift, und einer Rückstellvorrichtung, die am anderen Barrenende angreift.The invention relates to a warp knitting machine with at least one displaceable by predetermined paths Barre, like laying bar, a first controllable motor, which engages at a bar end and a reset device, that attacks at the other end of the bar.

Bei einer bekannten Kettenwirkmaschine dieser Art (DE 29 26 018 c2) weist der Motor ein Band auf, dessen Länge durch senkrecht zum Band versetzbare Druckelemente verkürzbar ist. Als Rückstellvorrichtung dient eine Feder. Diese Konstruktion erfordert zum Barrenversatz verhältnismäßig große Zugkräfte und, insbesondere bei der Anordnung von mehreren Barren dieser Art in einer Kettenwirkmaschine, ein sehr stabiles Maschinengestell. Auch sind der Arbeitsgeschwindigkeit Grenzen gesetzt.In a known warp knitting machine of this type (DE 29 26 018 c2) the engine has a belt, the Length thanks to pressure elements that can be moved perpendicular to the belt can be shortened. A serves as a reset device Feather. This construction requires to offset the bars relatively large tractive forces and, especially at the arrangement of several bars of this type in one Warp knitting machine, a very stable machine frame. There are also limits to the speed of work.

Ferner ist es bekannt (DE 30 06 636 A1),die Barren einer Kettenwirkmaschine als Legebänder auszuführen und durch Profilierung zu versteifen. It is also known (DE 30 06 636 A1), the bars of a Warp knitting machine as laying tapes and stiffen by profiling.

Der Erfindung liegt die Aufgabe zugrunde, eine Kettenwirkmaschine der eingangs genannten Art anzugeben, die mit geringeren Zugkräften arbeitet und auch für höhere Betriebsgeschwindigkeiten geeignet ist.The invention has for its object a warp knitting machine of the type mentioned at the outset works with lower tractive forces and also for higher ones Operating speeds is suitable.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß als Rückstellvorrichtung ein zweiter steuerbarer Motor dient und daß mittels einer Steuervorrichtung der erste Motor die Barre um vorbestimmte Wege in der einen Versatzrichtung und der zweite Motor die Barre um vorbestimmte Wege in der anderen Versatzrichtung zieht und der jeweils andere Motor eine entgegengerichtete Spannkraft auf die Barre ausübt.This object is achieved in that as a reset device, a second controllable motor serves and that the first by means of a control device Motor the bar by predetermined distances in one direction of offset and the second motor the bar by predetermined Draws paths in the other direction and the other motor has an opposing clamping force on the bar.

Bei dieser Konstruktion stehen wesentlich größere Kräfte zur Beschleunigung zur Verfügung. Denn früher mußten die Motoren in der einen Versatzrichtung nicht nur die für eine Beschleunigung erforderlichen Zugkräfte aufbringen, sondern auch noch die Kraft der Rückstellfeder, die in der gleichen Größenordnung liegt, überwinden. Jetzt wirkt der Verstellkraft nur noch eine Spannkraft entgegen, die relativ klein gehalten werden kann. Es steht daher ein ganz erheblicher Zugkraftüberschuß für eine raschere Beschleunigung und damit eine höhere Betriebsgeschwindigkeit zur Verfügung. Hinzu kommt, daß ein Maschinengestell mit geringerer Stabilität verwendet werden kann, weil die im Betrieb beim Bandversatz auftretenden Kräfte kleiner als bisher gehalten werden können..In this construction there are much greater forces available for acceleration. Because earlier had to the motors in one direction of offset not just that apply tensile forces required for acceleration, but also the force of the return spring, of the same order of magnitude. Now the adjustment force only has a clamping force opposed, which can be kept relatively small. There is therefore a very considerable tractive power surplus for faster acceleration and therefore higher Operating speed available. On top of that used a machine frame with less stability can be because of the operation of the belt offset occurring forces are kept smaller than before can..

Vorteilhaft ist es, daß die Barre als Band ausgebildet ist. Die Masse der Barre ist äußerst klein, so daß schon geringe Zugkräfte ausreichen, um die für einen raschen Versatz erforderlichen Beschleunigungen zu erzielen. Auch die Spannkraft kann klein gehalten werden, da sie lediglich das in der Regel biegsame Band gestreckt halten muß.It is advantageous that the bar is designed as a band is. The mass of the bar is extremely small, so that Even low tractive forces are sufficient to to achieve rapid offset required accelerations. The clamping force can also be kept low, since they just stretched the usually flexible tape must hold.

Günstig ist es, daß die Steuervorrichtung einen PI-Regler zum Steuern des ersten oder zweiten Motors und einen von einem P-Anteil beeinflußten Regler zum Steuern des jeweils anderen Motors aufweist. Der PI-Regler dient demnach als Master und der durch die P-Anteile beeinflußte Regler als Slave. Auf diese Weise wird eine Verknüpfung der Betriebsweise der beiden Motoren hergestellt, gemäß der die Spannkräfte immer klein im Vergleich zu den Zugkräften sind. Dies gilt für beide Versatzrichtungen.It is favorable that the control device has a PI controller to control the first or second motor and a controller influenced by a P component for controlling of the other motor. The PI controller therefore serves as a master and by the P components influenced controllers as slaves. In this way, one Linkage of the operating mode of the two motors is established, according to which the clamping forces are always small in comparison to the tractive forces. This applies to both directions of offset.

Empfehlenswert ist es, daß die Steuervorrichtung einen Regler aufweist, dem Ist- und Sollwerte der Barrenlage als Absolutwerte zugeführt werden. Da hierbei jedem Ort ein eigener Absolutwert zugeordnet ist, kann die Kettenwirkmaschine aus jeder beliebigen Lage angefahren werden. Eine Null-Justierung erübrigt sich.It is recommended that the control device one Controller has, the actual and target values of the ingot position are supplied as absolute values. Because here every place The warp knitting machine can be assigned its own absolute value approached from any position become. A zero adjustment is not necessary.

In diesem Zusammenhang ist es interessant, daß die Skala des Istwertgebers für die Barrenlage am Band montiert ist. Das Band hat eine flache Oberfläche, auf der sich die Skala bequem anbringen läßt.In this context it is interesting that the scale of the actual value transmitter for the bar position mounted on the conveyor is. The tape has a flat surface on which the scale can be easily attached.

Ein weiterer Vorteil ergibt sich dadurch, daß der Gesamtverstellweg der Barre mindestens 150 mm beträgt. In der Praxis kommen auch 180 oder 200 mm in Betracht. Ein so großer Gesamtverstellweg war bisher nicht möglich, weil die Rückstellfeder eine so große Längenänderung nicht zugelassen hat. Nunmehr kann man den aktuellen Verstellbereich von beispielsweise 16 mm innerhalb des großen Gesamtverstellwegs verschieben, ohne daß an der Maschine Änderungen vorgenommen werden müßten.Another advantage is that the total adjustment the bar is at least 150 mm. In in practice, 180 or 200 mm are also possible. On such a large total adjustment path was previously not possible, because the return spring makes such a big change in length has not approved. Now you can see the current one Adjustment range of, for example, 16 mm within the shift large total adjustment range without the Machine changes would have to be made.

Mit besonderem Vorteil sind die Motoren Linearmotoren. Sie können in unmittelbarer Verlängerung des Bandes angeordnet sein und benötigen keine Umlenkvorrichtungen.The motors are particularly advantageous as linear motors. They can be arranged in the immediate extension of the tape be and do not require deflection devices.

Statt dessen können die Motoren Rotationsmotoren sein. Sie können beispielsweise eine Scheibe drehen, über die ein Zugseil gelegt ist, das zum Bandende führt.Instead, the motors can be rotary motors. For example, you can rotate a disc over the a traction rope is laid that leads to the end of the belt.

Bei einer bevorzugten Ausführungsform ist dafür gesorgt, daß das Band Fadenführerelemente trägt. Diese können an den Stellen angebracht werden, an denen sie aus Musterungegründen benötigt werden.In a preferred embodiment, it is ensured that that the tape carries thread guide elements. This can be placed where they are are needed for pattern reasons.

Bei einer ebenfalls vorteilhaften Alternative weist das Band Löcher zur Fadenführung auf.In an equally advantageous alternative, this Tape holes for thread guidance.

Die Erfindung wird im folgenden anhand in der Zeichnung dargestellter bevorzugter Ausführungsbeispiel näher erläutert. Es zeigen:

The invention is explained in more detail below with reference to the preferred exemplary embodiment shown in the drawing. Show it:

another embodiment of the tape and
Fig. 3
another embodiment of the tape.

In Fig. 1 ist ein biegsames Band 1 gezeigt, das als Legeband einer Kettenwirkmaschine dienen kann. Das Ende 2 des Bandes 1 ist mit dem Läufer 3 eines Linearmotors 4, das Ende 5 des Bandes 1 mit dem Läufer 6 eines Linearmotors 7 verbunden. Beide Motoren 4 und 7 üben lediglich Zugkräfte auf das Band 1 aus. Soll das Band 1 nach links versetzt werden, zieht der Motor 4 das Band um den entsprechenden Versatzweg nach links. Gleichzeitig wird der Motor 7 so angesteuert, daß er eine verhältnismäßig geringe Spannkraft ausübt, so daß das Band 1 gestreckt bleibt. Soll das Band 1 nach rechts versetzt werden, übt der Motor 7 die Zugkraft aus, die zum Versetzen notwendig ist, wobei der Motor 4 die Spannkraft zum Gestreckthalten des Bandes 1 erzeugt.In Fig. 1, a flexible tape 1 is shown, which is a laying tape can serve a warp knitting machine. The end 2 of the belt 1 is with the rotor 3 of a linear motor 4, the end 5 of the band 1 with the rotor 6 of a linear motor 7 connected. Both engines 4 and 7 only practice Tensile forces on tape 1. Should the volume 1 after are shifted to the left, the motor 4 pulls the belt the corresponding offset path to the left. At the same time the motor 7 is driven so that it is a relative exerts little tension, so that the tape 1 stays stretched. Should volume 1 be shifted to the right are, the motor 7 exerts the tensile force that is required to move is necessary, the motor 4 the clamping force to keep the tape 1 stretched.

Um die beiden Motoren 4 und 7 im beschriebenen Sinn anzusteuern, ist eine Steuervorrichtung 8 vorgesehen, die über eine Leitung 9 die Leistung des Motors 4 bestimmende Signale und über eine Leitung 10 die Leistung des Motors 7 bestimmende Signale vorgibt. Die Steuervorrichtung 8 weist einen PI-Regler 11 auf, dem über einen Eingang 12 die Sollwerte der Versatzbewegung von einem Programmgeber 13 in der Form von Absolutwerten zugeführt werden. Der Programmgeber 13 arbeitet in Abhängigkeit von der Hauptwellendrehzahl der Kettenwirkmaschine. Außerdem wird dem PI-Regler 11 über einen zweiten Eingang 14 der Istwert der Lage des Bandes 1 zugeführt, zu welchem Zweck eine Skala 15 auf dem Band 1 angeordnet ist, die von einem Lesekopf 16 optisch oder auf andere Weise abgetastet wird. Über einen ersten Ausgang 17 werden die Leistungsdaten des in Versatzrichtung ziehenden Motors an eine Umschaltvorrichtung 18 weitergegeben. Über einen zweiten Ausgang 19 wird ein Slave-Regler 20 beeinflußt. Er berücksichtigt einen Anteil der P-Komponente des PI-Reglers 11 und gibt am Ausgang 21 ein Signal an die Umschaltvorrichtung 18 ab, das derjenigen Motorleistung entspricht, die der Erzeugung einer brauchbaren kleinen Spannkraft entspricht. Die Umschaltvorrichtung 18 erkennt am Vorzeichen des über die Leitung 17 zugeführten Signals, welche Versatzrichtung gefordert wird.In order to control the two motors 4 and 7 as described, a control device 8 is provided which Determine the power of the motor 4 via a line 9 Signals and the power of the line 10 Motors 7 specifies signals. The control device 8 has a PI controller 11, via which a Input 12 the setpoints of the offset movement of one Programmer 13 supplied in the form of absolute values become. The programmer 13 works in dependence from the main shaft speed of the warp knitting machine. In addition, the PI controller 11 via a second Input 14 of the actual value of the position of belt 1 is fed, for what purpose a scale 15 on tape 1 is arranged optically or by a read head 16 is scanned in a different way. About a first Output 17 will show the performance data in the offset direction pulling motor to a switching device 18 passed. Via a second output 19 a slave controller 20 affects. He takes one into account Share of the P component of the PI controller 11 and gives on Output 21 sends a signal to the switching device 18, that corresponds to the engine power that the generation corresponds to a usable small clamping force. The switching device 18 recognizes by the sign of the Signal fed via line 17, which direction of offset is required.

Bei einer Versatzbewegung nach links erzeugt daher der Motor 4 eine Zugkraft P1 und der Motor 7 eine erheblich kleinere Spannkraft S1, wie es in Fig. 1 durch Pfeile dargestellt ist. Wenn dagegen der Versatz nach rechts erfolgen soll, erzeugt der Motor 7 eine Zugkraft P2 und der Motor 4 eine Spannkraft S2, wie es durch gestrichelte Pfeile in Fig. 1 dargestellt ist.With an offset movement to the left, the Motor 4 a pulling force P1 and the motor 7 a considerable smaller clamping force S1, as shown in Fig. 1 by arrows is shown. If, on the other hand, the offset to the right should take place, the motor 7 generates a tensile force P2 and the motor 4 has a clamping force S2 as shown by dashed lines Arrows in Fig. 1 is shown.

Bei der Ausführungsform gemäß Fig. 2 ist ein Band 22 vorgesehen, das mit Fadenführerelementen 23 bestückt ist. Es kann sich auch um andere Wirkwerkzeuge, beispielsweise Platinen, handeln. Statt der Motoren 4 und 7, die als Linearmotoren ausgebildet sind, werden hier Rotationsmotoren 24 und 25 verwendet, die, was nur schematisch angedeutet ist, eine Seilwinde antreiben. Des weiteren ist gezeigt, daß das Band 22 über Halterungen 26 auf Bolzen 27 verschiebbar ist, die an Trägern 28 befestigt sind.2 is a band 22 provided that equipped with thread guide elements 23 is. It can also be other knitting tools, for example Circuit boards, trade. Instead of motors 4 and 7, which are designed as linear motors, are here Rotary motors 24 and 25 used what only is indicated schematically, drive a winch. It is also shown that the band 22 has brackets 26 is displaceable on bolt 27, which is on beams 28 are attached.

Bei der Ausführungsform nach Fig. 3 ist das Band 29 an einem Ende mit einem Rotationsmotor 30 und am anderen Ende mit einem Rotationsmotor 31 verbunden. Das Band besitzt eine Vielzahl von Löchern 32 zur Fadenführung. Außerdem sind Führungsschlitze 33 vorgesehen, durch welche je eine Stützrolle 34 greift.In the embodiment according to FIG. 3, the band 29 is on one end with a rotary motor 30 and the other End connected to a rotary motor 31. The ribbon has a plurality of holes 32 for thread guidance. In addition, guide slots 33 are provided through which each engages a support roller 34.
