Definitions
- the invention relates to a warp knitting machine with a bar that is movable back and forth along a bar longitudinal axis, with a ram that engages the bar, with a thrust body for exerting a force on the ram and with a spring tension system that moves the bar into Pulls direction of the plunger, wherein the spring tension system has a force transmission arrangement and at least one spring.
- Warp knitting machines of this type are known from the prior art. So shows the CN 205676612 U an arrangement that allows a bar to be driven via a ram. A pattern device is used to offset the bar. This drives a thrust body, which in turn is connected to the plunger. The arrangement also has a cylindrical tensile body.
- the present invention is therefore based on the object of providing a warp knitting machine with a spring tension system that can withstand higher mechanical loads.
- the object is achieved by providing a warp knitting machine in which the thrust body has a guide channel, wherein the at least one spring is arranged in the guide channel and wherein a section of the force transmission arrangement of the spring tension system is mounted in the guide channel.
- the inventive arrangement of the spring in the thrust body results in a greatly improved stability.
- the thrust body can absorb forces and safely dissipate them.
- the restoring force exerted by the spring acts on the force transmission arrangement in such a way that the bar is pressed against the ram.
- the thrust body is preferably designed in one piece.
- the bar can be a guide bar.
- Several needles that guide the warp threads are attached to the guide bar.
- the guide bar is displaced along the longitudinal axis of the bar to produce a knitted fabric with a desired pattern.
- the warp knitting machine can have a pattern device for moving the guide bar.
- the pattern device can contain a pattern disk which, due to its outer profile, displaces the bar when it rotates.
- the pattern device it is possible for the pattern device to have a servomotor or a linear motor. Such a motor makes it possible to freely set an offset position of the bar. This opens up a very large variety of patterns to the user.
- the force transmission arrangement preferably has a bolt which is mounted in the thrust body.
- the bolt can be slidably mounted in the thrust body.
- the force transmission arrangement has a tension element which can be connected to the bar.
- the tension element can be connected to the bolt. It can be provided according to the invention that the tension element is a metal cable.
- the guide channel is preferably oriented in the thrust body in such a way that a guide channel longitudinal axis of the guide channel and the bar longitudinal axis are not oriented parallel to one another.
- the longitudinal axis of the guide channel is an imaginary axis along which the bolt can be displaced within the guide channel. If the tension element is tensioned between the thrust body and the bar so that it runs in a direction transverse to the longitudinal axis of the bar, then considerable transverse forces can act on the guide channel. This is avoided by adapting the alignment of the guide channel.
- a tension element longitudinal axis of the tension element and the guide channel longitudinal axis are aligned parallel to one another.
- the longitudinal axis of the tension element denotes an imaginary longitudinal axis of the tension element under tension. If the longitudinal axis of the tension element and the longitudinal axis of the guide channel are aligned parallel to one another, transverse forces on the guide channel are minimized.
- the guide channel in the thrust body is aligned in such a way that the guide channel longitudinal axis of the guide channel is inclined in the direction of a fastening section of the bar on which the force transmission arrangement of the spring tension system can be connected to the bar. Lateral forces on the guide channel are thus reduced.
- the fastening section is formed by a holding part which extends from a bar body of the bar in a direction transverse to the longitudinal axis of the bar.
- the holding part can be designed as a pin, a hook or the like.
- the fastening section can also be formed directly by the bar. It is thus possible according to the invention for the bar body to have a recess into which an end section of the tension element engages.
- a longitudinal axis of the tension element of the tension element preferably forms an angle with the longitudinal axis of the bar when the tension element is attached to the bar.
- the longitudinal axis of the tension element denotes an imaginary longitudinal axis of the tension element under tension.
- the angle can be an angle greater than 0 °. Such an angle is obtained in particular if the bar has only a small overall height. In this case, the tension element must necessarily be guided at an angle between the bar and the thrust body, because otherwise the spring tension system and the plunger would have to be arranged very close to one another.
- one side of the thrust body which faces away from the bar has an opening which provides access to the force transmission arrangement in the thrust body.
- the pulling element exerts a pulling force on the bar.
- the bar loads the ram in the direction of force under pressure.
- the ram is thereby held securely between the bar and the thrust body, but it is not possible to manually move the bar away from the ram so that it can be removed.
- the pulling force is too great for this.
- the side of the thrust body facing away from the bar offers a suitable access in order to move the bolt of the force transmission arrangement, for example by means of a tool or a drive. This reduces the force exerted by the tension element on the bar and the ram can be removed.
- a section of the force transmission arrangement protrudes from the opening.
- the section can be a section of the bolt of the force transmission arrangement.
- the bolt is therefore very easily accessible and can be displaced by exerting a pressing force. This can be achieved by displacing a stop so that it exerts a contact pressure on the bolt and displaces it. Alternatively, this can be achieved by moving the thrust body in the direction of the stop, so that the bolt is pressed against the stop, whereby the bolt is displaced in the thrust body.
- the warp knitting machine preferably has a lifting drive which can exert a force on the force transmission arrangement via a lifting element, so that the force transmission arrangement is displaced in the guide channel.
- a lifting drive which can exert a force on the force transmission arrangement via a lifting element, so that the force transmission arrangement is displaced in the guide channel.
- This allows the tensile force exerted on the bar to be automatically adjusted. For example, an input can be made via a control system of the warp knitting machine, since the bar needs to be changed.
- the bolt of the power transmission arrangement is now automatically moved into a new position by the excavation drive and held in the new position. After removing the ram and changing the bar, a new entry is made to signal that the process has been completed. The The excavation drive then releases the bolt so that the springs can move the bolt back into its original position.
- the lifting element is preferably a stop which can be displaced in such a way that it can come into operative connection with the force transmission arrangement.
- the stop only comes into contact with the force transmission arrangement when it is to be displaced. According to the invention, however, it is also possible for the lifting element to be firmly connected to the force transmission arrangement.
- Fig. 1 shows a schematic representation of a spring tension system 1, a bar 2 and a push body 3 of a warp knitting machine according to the invention in a side view.
- Bar 2 is a guide bar.
- the bar 2 is only shown in sections.
- a plunger 4 is arranged between the thrust body 3 and the bar 2.
- the ram 4 can apply forces to the bar 2 from a pattern device, not shown, of the warp knitting machine transferred so that the bar 2 is moved along a bar longitudinal axis 5, which is shown by a dashed line.
- a force transmission arrangement 6 exerts a restoring force on the bar 2, so that the bar 2 is pressed against the plunger 4.
- the force transmission arrangement 6 has a bolt 7, a deflection element 8 and a tension element 9.
- the pulling element 9 is a pulling rope made of metal.
- the tension element 9 is fastened to a fastening section 10 of the bar 2.
- the fastening section 10 is a pin which is fastened to a bar body 11 of the bar 2. It can be seen that the tension element 9 is not aligned parallel to the longitudinal axis 5 of the bars.
- Fig. 2 shows a schematic representation of the spring tension system 1 and the thrust body 3 in a sectional view.
- the spring tension system 1 is formed by the force transmission arrangement 6 and several springs, the springs being located in spring assemblies 12.
- the springs exert a restoring force on the bolt 7 of the force transmission arrangement 6.
- the bar 2 is thus pressed against the plunger 4.
- the bolt 7 is slidably mounted in a guide channel 13 of the thrust body 3.
- a guide channel longitudinal axis 14 of the guide channel 13, shown by a dashed line, does not run parallel to the bar longitudinal axis 5. Transverse forces in the thrust body 3 are thus minimized.
- the thrust body 3 has an opening 15 from which the bolt 7 protrudes. The bolt 7 is thus accessible from the outside and can be moved if necessary.

Die Erfindung betrifft eine Kettenwirkmaschine mit einer Barre, die entlang einer Barren-Längsachse hin und her beweglich ist, mit einem Stößel, der an die Barre angreift, mit einem Schubkörper zur Ausübung einer Kraft auf den Stößel und mit einem Federzugsystem, das die Barre in Richtung des Stößels zieht, wobei das Federzugsystem eine Kraftübertragungsanordnung und mindestens eine Feder aufweist. Kettenwirkmaschinen dieser Art sind aus dem Stand der Technik bekannt. So zeigt die
Der vorliegenden Erfindung liegt deshalb die Aufgabe zugrunde, eine Kettenwirkmaschine mit einem Federzugsystem bereitzustellen, das mechanisch höher belastbar ist.The present invention is therefore based on the object of providing a warp knitting machine with a spring tension system that can withstand higher mechanical loads.
Die Aufgabe wird gelöst, indem eine Kettenwirkmaschine bereitgestellt wird, bei der der Schubkörper einen Führungskanal aufweist, wobei die mindestens eine Feder in dem Führungskanal angeordnet ist und wobei ein Abschnitt der Kraftübertragungsanordnung des Federzugsystems in dem Führungskanal gelagert ist.The object is achieved by providing a warp knitting machine in which the thrust body has a guide channel, wherein the at least one spring is arranged in the guide channel and wherein a section of the force transmission arrangement of the spring tension system is mounted in the guide channel.
Aufgrund der erfindungsgemäßen Anordnung der Feder in dem Schubkörper ergibt sich eine stark verbesserte Stabilität. Der Schubkörper kann Kräfte aufnehmen und sicher abführen. Die durch die Feder ausgeübte Rückstellkraft wirkt erfindungsgemäß so auf die Kraftübertragungsanordnung, dass die Barre an den Stößel gedrückt wird. Der Schubkörper ist bevorzugt einstückig ausgebildet.The inventive arrangement of the spring in the thrust body results in a greatly improved stability. The thrust body can absorb forces and safely dissipate them. According to the invention, the restoring force exerted by the spring acts on the force transmission arrangement in such a way that the bar is pressed against the ram. The thrust body is preferably designed in one piece.
Bei der Barre kann es sich erfindungsgemäß um eine Legebarre handeln. An der Legebarre werden mehrere Legenadeln befestigt, die Kettfäden führen. Die Legebarre wird zur Erzeugung einer Wirkware mit einer gewünschten Musterlegung entlang der Barrenlängsachse verlagert. Die Kettenwirkmaschine kann erfindungsgemäß eine Mustereinrichtung zur Verlagerung der Legebarre aufweisen. Die Mustereinrichtung kann gemäß einer Ausführungsform der Erfindung eine Musterscheibe enthalten, die aufgrund ihres Außenprofils bei Drehung die Barre verlagert. Alternativ ist es möglich, dass die Mustereinrichtung einen Servomotor oder einen Linearmotor aufweist. Ein solcher Motor ermöglicht es, eine Versatzposition der Barre frei einzustellen. Dies eröffnet dem Benutzer eine sehr große Musterungsvielfalt.According to the invention, the bar can be a guide bar. Several needles that guide the warp threads are attached to the guide bar. The guide bar is displaced along the longitudinal axis of the bar to produce a knitted fabric with a desired pattern. According to the invention, the warp knitting machine can have a pattern device for moving the guide bar. According to one embodiment of the invention, the pattern device can contain a pattern disk which, due to its outer profile, displaces the bar when it rotates. Alternatively, it is possible for the pattern device to have a servomotor or a linear motor. Such a motor makes it possible to freely set an offset position of the bar. This opens up a very large variety of patterns to the user.
Vorzugsweise weist die Kraftübertragungsanordnung einen Bolzen auf, der in dem Schubkörper gelagert ist. Der Bolzen kann erfindungsgemäß in dem Schubkörper gleitend gelagert sein.The force transmission arrangement preferably has a bolt which is mounted in the thrust body. According to the invention, the bolt can be slidably mounted in the thrust body.
Alternativ kann in dem Schubkörper aber auch ein Kugel- oder ein Rollenlager angeordnet sein. Es ist vorteilhaft, wenn die Kraftübertragungsanordnung ein Zugelement aufweist, das mit der Barre verbindbar ist. Das Zugelement kann erfindungsgemäß mit dem Bolzen verbunden sein. Es kann erfindungsgemäß vorgesehen sein, dass das Zugelement ein Metallseil ist.Alternatively, however, a ball or roller bearing can also be arranged in the thrust body. It is advantageous if the force transmission arrangement has a tension element which can be connected to the bar. According to the invention, the tension element can be connected to the bolt. It can be provided according to the invention that the tension element is a metal cable.
Der Führungskanal ist vorzugsweise in dem Schubkörper so ausgerichtet, dass eine Führungskanal-Längsachse des Führungskanals und die Barren-Längsachse nicht parallel zueinander ausgerichtet sind. Bei der Führungskanal-Längsachse handelt es sich um eine gedachte Achse, entlang welcher der Bolzen innerhalb des Führungskanals verlagerbar ist. Wenn das Zugelement zwischen dem Schubkörper und der Barre so gespannt wird, dass es in einer Querrichtung zu der Barren-Längsachse verläuft, dann können erhebliche Querkräfte auf den Führungskanal wirken. Dies wird durch eine Anpassung der Ausrichtung des Führungskanals vermieden.The guide channel is preferably oriented in the thrust body in such a way that a guide channel longitudinal axis of the guide channel and the bar longitudinal axis are not oriented parallel to one another. The longitudinal axis of the guide channel is an imaginary axis along which the bolt can be displaced within the guide channel. If the tension element is tensioned between the thrust body and the bar so that it runs in a direction transverse to the longitudinal axis of the bar, then considerable transverse forces can act on the guide channel. This is avoided by adapting the alignment of the guide channel.
Es ist vorteilhaft, wenn eine Zugelement-Längsachse des Zugelements und die Führungskanal-Längsachse parallel zueinander ausgerichtet sind. Die Zugelement-Längsachse bezeichnet eine gedachte Längsachse des Zugelements unter Spannung. Wenn die Zugelement-Längsachse und die Führungskanal-Längsachse parallel zueinander ausgerichtet sind, dann werden Querkräfte auf den Führungskanal minimiert.It is advantageous if a tension element longitudinal axis of the tension element and the guide channel longitudinal axis are aligned parallel to one another. The longitudinal axis of the tension element denotes an imaginary longitudinal axis of the tension element under tension. If the longitudinal axis of the tension element and the longitudinal axis of the guide channel are aligned parallel to one another, transverse forces on the guide channel are minimized.
Es ist bevorzugt, wenn der Führungskanal in dem Schubkörper so ausgerichtet ist, dass die Führungskanal-Längsachse des Führungskanals in Richtung eines Befestigungsabschnitts der Barre geneigt ist, an dem die Kraftübertragungsanordnung des Federzugsystems mit der Barre verbindbar ist. Querkräfte auf den Führungskanal werden somit reduziert.It is preferred if the guide channel in the thrust body is aligned in such a way that the guide channel longitudinal axis of the guide channel is inclined in the direction of a fastening section of the bar on which the force transmission arrangement of the spring tension system can be connected to the bar. Lateral forces on the guide channel are thus reduced.
Es ist vorteilhaft, wenn der Befestigungsabschnitt durch ein Halteteil gebildet wird, das sich aus einem Barrenkörper der Barre in einer Richtung quer zu der Barren-Längsachse erstreckt. Das Halteteil kann erfindungsgemäß als ein Stift, als ein Haken oder dergleichen ausgebildet sein. Der Befestigungsabschnitt kann alternativ jedoch auch unmittelbar durch die Barre gebildet werden. So ist es erfindungsgemäß möglich, dass der Barrenkörper eine Ausnehmung aufweist, in die ein Endabschnitt des Zugelements eingreift.It is advantageous if the fastening section is formed by a holding part which extends from a bar body of the bar in a direction transverse to the longitudinal axis of the bar. According to the invention, the holding part can be designed as a pin, a hook or the like. Alternatively, however, the fastening section can also be formed directly by the bar. It is thus possible according to the invention for the bar body to have a recess into which an end section of the tension element engages.
Vorzugsweise schließt eine Zugelement-Längsachse des Zugelements mit der Barren-Längsachse einen Winkel ein, wenn das Zugelement an der Barre befestigt ist. Die Zugelement-Längsachse bezeichnet eine gedachte Längsachse des Zugelements unter Spannung. Bei dem Winkel kann es sich erfindungsgemäß um einen Winkel größer als 0° handeln. Ein solcher Winkel ergibt sich insbesondere dann, falls die Barre nur eine geringe Bauhöhe aufweist. Das Zugelement muss in diesem Fall zwangsläufig zwischen der Barre und dem Schubkörper schief geführt werden, denn andernfalls müssten das Federzugsystem und der Stößel sehr nah beieinander angeordnet werden.A longitudinal axis of the tension element of the tension element preferably forms an angle with the longitudinal axis of the bar when the tension element is attached to the bar. The longitudinal axis of the tension element denotes an imaginary longitudinal axis of the tension element under tension. According to the invention, the angle can be an angle greater than 0 °. Such an angle is obtained in particular if the bar has only a small overall height. In this case, the tension element must necessarily be guided at an angle between the bar and the thrust body, because otherwise the spring tension system and the plunger would have to be arranged very close to one another.
Gemäß einer vorteilhaften Ausführungsform der Erfindung weist eine Seite des Schubkörpers, die von der Barre abgewandt ist, eine Öffnung auf, die einen Zugang zu der Kraftübertragungsanordnung in dem Schubkörper herstellt. Dies kann man sich im folgenden Anwendungsfall zunutze machen. Das Zugelement übt auf die Barre eine Zugkraft aus. Somit belastet die Barre den Stößel in Kraftrichtung auf Druck. Der Stößel wird dadurch sicher zwischen der Barre und dem Schubkörper gehalten, aber es ist nicht möglich, die Barre händisch von dem Stößel wegzubewegen, sodass dieser entfernt werden kann.According to an advantageous embodiment of the invention, one side of the thrust body which faces away from the bar has an opening which provides access to the force transmission arrangement in the thrust body. This can be used in the following application. The pulling element exerts a pulling force on the bar. Thus, the bar loads the ram in the direction of force under pressure. The ram is thereby held securely between the bar and the thrust body, but it is not possible to manually move the bar away from the ram so that it can be removed.
Die Zugkraft ist hierfür zu groß. Die von der Barre abgewandte Seite des Schubkörpers bietet einen geeigneten Zugang, um den Bolzen der Kraftübertragungsanordnung beispielsweise mittels eines Werkzeugs oder eines Antriebs zu verlagern. Dadurch sinkt die von dem Zugelement auf die Barre ausgeübte Kraft und der Stößel kann entnommen werden.The pulling force is too great for this. The side of the thrust body facing away from the bar offers a suitable access in order to move the bolt of the force transmission arrangement, for example by means of a tool or a drive. This reduces the force exerted by the tension element on the bar and the ram can be removed.
Es ist vorteilhaft, wenn ein Abschnitt der Kraftübertragungsanordnung aus der Öffnung hervorragt. Es kann sich bei dem Abschnitt um einen Abschnitt des Bolzens der Kraftübertragungsanordnung handeln. Der Bolzen ist somit sehr einfach zugänglich und kann durch Ausübung einer Anpresskraft verlagert werden. Dies kann dadurch bewirkt werden, dass ein Anschlag verlagert wird, sodass er auf den Bolzen eine Anpresskraft ausübt und diesen verlagert. Dies kann alternativ bewirkt werden, indem der Schubkörper in Richtung des Anschlags bewegt wird, sodass der Bolzen an den Anschlag angedrückt wird, wodurch der Bolzen im Schubkörper verlagert wird.It is advantageous if a section of the force transmission arrangement protrudes from the opening. The section can be a section of the bolt of the force transmission arrangement. The bolt is therefore very easily accessible and can be displaced by exerting a pressing force. This can be achieved by displacing a stop so that it exerts a contact pressure on the bolt and displaces it. Alternatively, this can be achieved by moving the thrust body in the direction of the stop, so that the bolt is pressed against the stop, whereby the bolt is displaced in the thrust body.
Vorzugsweise weist die Kettenwirkmaschine einen Aushebungsantrieb auf, der über ein Hubelement eine Kraft auf die Kraftübertragungsanordnung ausüben kann, sodass die Kraftübertragungsanordnung in dem Führungskanal verlagert wird. Dies erlaubt es, die auf die Barre ausgeübte Zugkraft automatisch anzupassen. So kann beispielsweise über ein Steuerungssystem der Kettenwirkmaschine eine Eingabe getätigt werden, da ein Wechsel der Barre ansteht. Der Bolzen der Kraftübertragungsanordnung wird nun von dem Aushebungsantrieb automatisch in eine neue Position verlagert und in der neuen Position gehalten. Nach der Entfernung des Stößels und dem Wechsel der Barre wird eine erneute Eingabe getätigt, um zu signalisieren, dass der Vorgang abgeschlossen ist. Der Aushebungsantrieb gibt dann den Bolzen frei, sodass die Federn den Bolzen wieder in seine ursprüngliche Position bewegen können.The warp knitting machine preferably has a lifting drive which can exert a force on the force transmission arrangement via a lifting element, so that the force transmission arrangement is displaced in the guide channel. This allows the tensile force exerted on the bar to be automatically adjusted. For example, an input can be made via a control system of the warp knitting machine, since the bar needs to be changed. The bolt of the power transmission arrangement is now automatically moved into a new position by the excavation drive and held in the new position. After removing the ram and changing the bar, a new entry is made to signal that the process has been completed. The The excavation drive then releases the bolt so that the springs can move the bolt back into its original position.
Vorzugsweise ist das Hubelement ein Anschlag, der so verlagerbar ist, dass er mit der Kraftübertragungsanordnung in Wirkverbindung treten kann. Der Anschlag tritt mit der Kraftübertragungsanordnung nur in Kontakt, wenn diese verlagert werden soll. Es ist aber erfindungsgemäß auch möglich, dass das Hubelement mit der Kraftübertragungsanordnung fest verbunden ist.The lifting element is preferably a stop which can be displaced in such a way that it can come into operative connection with the force transmission arrangement. The stop only comes into contact with the force transmission arrangement when it is to be displaced. According to the invention, however, it is also possible for the lifting element to be firmly connected to the force transmission arrangement.
