Definitions
- the present invention relates to a warp knitting machine having a warp beam with a pin, the warp beam being journalled on the pin by a bearing arranged on the warp knitting machine and the warp beam being driven by a torque transmission arrangement on the pin.
- EP 1 057 912 A1 describes a weaving machine with a warp beam which has projections on one of its pins which interact with a drive coupling member so as to produce a torque-transmitting connection between the drive and the warp beam.
- the drive coupling member can be displaced in the axial direction of the warp beam.
- a bearing is arranged on the pin, as a result of which the warp beam can be held in a bearing housing.
- U.S. 5,058,398 describes a yarn feeding device for a circular knitting machine, in which warp beams are arranged in bearing shells that are open at the top.
- EP 2 141 269 A1 describes a warp beam holding device in which a bearing is arranged on a warp beam.
- the object on which the invention is based is that the handling of a warp beam of a warp knitting machine should be handled economically. This object is solved by the features of claim 1.
- a drive unit By separating the torque transmission arrangement and the bearing arrangement, a drive unit can be dimensioned much smaller because a bearing function of the drive unit is not required.
- the drive unit is only there for the actual drive.

- the bearing arrangement preferably has a bearing and a bearing shell which is open at the top, the bearing being arranged in the bearing shell which is open at the top.
- the camp is arranged on the warp beam and is connected to the warp beam emotional. Such an arrangement greatly simplifies the removal of the warp beam because there is no need to remove and fix the upper bearing shell. This simplifies the handling of the warp beam, which reduces set-up times and thus costs.
- the bearing shell preferably fixes the bearing in the axial direction. By fixing the bearing in the axial direction, an axial movement of the bearing and thus of the warp beam is prevented.
- the warp beam runs smoothly and the following machine arrangements do not have to compensate for any axial movement of the warp beam.
- a first geometry is arranged on a free end of the journal and the torque transmission arrangement has a second geometry connected to a drive, the first geometry and the second geometry being matched to one another.
- the adapted geometries allow torque to be transmitted from the drive to the warp beam. Furthermore, the warp beam can be changed with little effort due to the geometries. Changing the warp beam in this way means shorter set-up times, which are reflected in lower overall costs.
- the second geometry part of a geometry arrangement, is preferably open upwards in a rest position.
- the rest position is a position in which the warp beam can be changed.
- the warp beam can be removed from the torque transmission arrangement upwards without the warp beam having to be displaced in its axial direction. The same applies to inserting the warp beam. Due to the easy handling of the warp beam, the set-up time is reduced, and thus the set-up costs are reduced.

- the fixing element guarantees a positive connection between the first geometry on the warp beam and the second geometry on the drive.
- the torque transmission is ensured by the form fit and a possible play between the first geometry and the second geometry is reduced.

- the form fit can be achieved by moving the fixing element in the radial direction into the torque transmission position.
- a suitable direction of movement of the fixing element can be selected. This creative freedom enables an economical implementation adapted to the conditions.
- the fixing element is preferably actuated by a fixing mechanism.
- the fixing mechanism is used to transfer the fixing element from the release position to the torque transmission position.
- the warp beam can be released in a specific angular position by the fixing mechanism by the fixing mechanism moving the fixing element to the release position.

- the fixing mechanism preferably has the fixing element, a fixing element guide and at least one lever.
- the fixing element is guided through the fixing element guide in order to avoid tilting of the fixing element or other disturbances.
- the lever reduces the force required to move the fixing element. Reduced performance means less force is required, resulting in low running costs. This arrangement accordingly increases the efficiency of the warp knitting machine.
- the fixing mechanism preferably has a reset device.
- the resetting device prevents unwanted movement of the fixing element.
- the reset device increases the operational reliability of the arrangement.
- the torque transmission arrangement preferably has a sensor arrangement.
- the sensor arrangement can monitor the position of the fixing element and the angular position of the torque transmission device and can take on other safety-related monitoring tasks.
- the first geometry is detachably arranged on the free end of the pin.
- the connection between the geometry and the free end of the pin can be made by means of fasteners, such as screws or the like. Due to the detachable connection, the warp beam can be adapted to the respective needs and replaced if there are signs of wear.
- the first geometry and the free end of the pin are formed in one piece.
- a one-piece training reduces the acquisition costs.
- a high torque transmission option is achieved by a one-piece design.
- the warp beam can preferably be removed without tools.
- a tool-free warp beam change reduces set-up times and set-up costs. Furthermore, the scope for automation solutions is opened up by a tool-free change of the warp beam, since an operator is no longer needed.
- a pin 1 at one end of a warp beam 2 is shown.
- a bearing 3 and a first geometry 4 are arranged on the pin 1 .
- the first geometry 4 can be designed differently depending on the preferred embodiment. In the exemplary embodiment shown here, the first geometry 4 is detachably connected to the pin 1 .

- the limitations 6 prevent movement of the bearing 3 to be held in the axial direction.
- a second geometry 7 that is adapted to the first geometry 4 is also shown.
- the second geometry 7 is connected to a torque transmission element 8 .
- the second geometry 7 forms a geometry arrangement with the torque transmission element 8, which is open at the top in a rest position.
- two fixing elements 9 are arranged to be movable in the radial direction and are in a release position.
- the fixing elements 9 are shown in section in their release position.
- the fixing elements 9 can be moved by a mechanism 10a.
- In 4 is based on 3 shown how the fixing elements 9 perform a form fit for torque transmission between the first geometry 4 and the second geometry 7 behind it.
- the fixing elements 9 are in a torque transmission position.
- figure 5 is shown how the warp beam 2 is in the bearing shell 5.
- a further preferred embodiment with a fixing element 9 is shown.

- Figures 9 to 11 represent a further preferred embodiment.
- the first geometry 4 and the pin 1 are formed in one piece.
- the bearing shell 5 By attaching the bearing 3 to the warp beam 2, it is possible to design the bearing shell 5 as a bearing shell 5 that is open on one side. Due to the weight of the warp beam 2 and the relatively low peripheral speeds, the risk of the warp beam 2 jumping out of the bearing shell 5 is very low. It is thus possible to use the bearing shell 5 without a bearing cap.
- the torque transmission arrangement points with the open side of the second geometry 7 upwards.
- the reset mechanism 12 exerts a force that wants to move the fixing element 9 into the torque-transmitting position.
- the drive 13 counteracts the return mechanism 12 via the lever 10 and holds the fixing element 9 in the release position. But he can Drive 13 as a fluid cylinder, electric motor assembly, gear - be designed rack and pinion assemblies or the like.

- the drive 13 releases the lever 10 and the force of the reset mechanism 12 moves the fixing element 9 into the torque transmission position.
- the fixing element 9 now produces a form-fitting connection between the first geometry 4 and the second geometry 7 without taking on the task of bearing.
- the form fit is solely responsible for the torque transmission.
- the sensor arrangement 14 monitors the position in which the fixing element 9 is located. The sensor arrangement 14 can carry out this monitoring either directly on the fixing element 9 or indirectly by measuring the lever 10 or other elements which serve to actuate the fixing element 9 .
- the warp beam 2 can be driven according to the required conditions.
- the warp beam 2 and the torque transmission arrangement 8 are rotated into the rest position. This means that the geometry arrangement with the second geometry 7 is open at the top. A corresponding position is detected by the sensor arrangement 14 . Then the fixing element 9 is moved into the release position. For this purpose, the drive 13 moves the lever 10 against the force of the reset mechanism 12 and moves the fixing element into the release position. In this release position there is no form fit between the first geometry 4 and the second geometry 7. The warp beam 2 can be removed upwards and another warp beam can be inserted into the device.

Die vorliegende Erfindung betrifft eine Kettenwirkmaschine, die einen Kettbaum mit einem Zapfen aufweist, wobei der Kettbaum an dem Zapfen durch ein Lager gelagert ist, der an der Kettenwirkmaschine angeordnet ist, und der Kettbaum durch eine Drehmomentübertragungsanordnung an dem Zapfen angetrieben ist.
Es ist aus
Die der Erfindung zugrundeliegende Aufgabe ist, dass die Handhabung eines Kettbaums einer Kettenwirkmaschine wirtschaftlich gehandhabt werden soll. Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst.The object on which the invention is based is that the handling of a warp beam of a warp knitting machine should be handled economically. This object is solved by the features of
Durch eine Trennung der Drehmomentübertragungsanordnung und der Lageranordnung kann eine Antriebseinheit wesentlich kleiner dimensioniert werden, weil eine Lagerfunktion der Antriebseinheit nicht gebraucht wird. Die Antriebseinheit ist nur noch zum tatsächlichen Antrieb da. Weiterhin kann die Lageranordnung optimiert und auf die benötigten Bedürfnisse angepasst werden. Bei möglichen Versagensfällen kann weiterhin die Lageranordnung gesondert von der Antriebseinheit betrachtet und repariert werden und umgekehrt. Weiterhin kann durch diese Anordnung eine Handhabung der Kettbäume automatisiert werden.By separating the torque transmission arrangement and the bearing arrangement, a drive unit can be dimensioned much smaller because a bearing function of the drive unit is not required. The drive unit is only there for the actual drive. Furthermore, the bearing arrangement can be optimized and adapted to the required needs. In the event of possible failures, the bearing arrangement can still be viewed and repaired separately from the drive unit and vice versa. Furthermore, handling of the warp beams can be automated by this arrangement.
Vorzugsweise weist die Lageranordnung ein Lager und eine nach oben offene Lagerschale auf, wobei das Lager in der nach oben offenen Lagerschale angeordnet ist. Das Lager ist am Kettbaum angeordnet und wird mit dem Kettbaum bewegt. Durch eine solche Anordnung wird die Entnahme des Kettbaums stark vereinfacht, weil die Entfernung und Fixierung der oberen Lagerschale entfällt. Dadurch wird die Handhabung des Kettbaums vereinfacht, was die Rüstzeiten und damit die Kosten senkt.The bearing arrangement preferably has a bearing and a bearing shell which is open at the top, the bearing being arranged in the bearing shell which is open at the top. The camp is arranged on the warp beam and is connected to the warp beam emotional. Such an arrangement greatly simplifies the removal of the warp beam because there is no need to remove and fix the upper bearing shell. This simplifies the handling of the warp beam, which reduces set-up times and thus costs.
Vorzugsweise fixiert die Lagerschale das Lager in axialer Richtung. Durch die Fixierung des Lagers in axialer Richtung wird eine axiale Bewegung des Lagers und damit des Kettbaums verhindert. Der Kettbaum läuft ruhig und die folgenden Maschinenanordnungen müssen keine axiale Bewegung des Kettbaums ausgleichen.The bearing shell preferably fixes the bearing in the axial direction. By fixing the bearing in the axial direction, an axial movement of the bearing and thus of the warp beam is prevented. The warp beam runs smoothly and the following machine arrangements do not have to compensate for any axial movement of the warp beam.
Erfindungsgemäß ist an einem freien Ende des Zapfens eine erste Geometrie angeordnet und die Drehmomentübertragungsanordnung weist eine mit einem Antrieb verbundene zweite Geometrie auf, wobei die erste Geometrie und die zweite Geometrie an einander angepasst sind. Durch die angepassten Geometrien ist eine Drehmomentübertragung ausgehend von dem Antrieb auf den Kettbaum möglich. Weiterhin kann der Kettbaum durch die Geometrien mit wenig Aufwand gewechselt werden. Ein solcher Wechsel des Kettbaums bedeutet geringere Rüstzeiten, die sich in geringeren Gesamtkosten niederschlagen.According to the invention, a first geometry is arranged on a free end of the journal and the torque transmission arrangement has a second geometry connected to a drive, the first geometry and the second geometry being matched to one another. The adapted geometries allow torque to be transmitted from the drive to the warp beam. Furthermore, the warp beam can be changed with little effort due to the geometries. Changing the warp beam in this way means shorter set-up times, which are reflected in lower overall costs.
Vorzugsweise ist die zweite Geometrie, Bestandteil einer Geometrieanordnung, in einer Ruheposition nach oben geöffnet. Die Ruheposition ist eine Position, in der ein Wechsel des Kettbaums vorgenommen werden kann. Dazu kann der Kettbaum aus der Drehmomentübertragungsanordnung nach oben entnommen werden, ohne das der Kettbaum in seiner axialen Richtung verschoben werden muss. Gleiches gilt für ein Einsetzen des Kettbaums. Durch die einfache Handhabung des Kettbaums wird die Rüstzeit reduziert, und somit werden die Rüstkosten gesenkt.The second geometry, part of a geometry arrangement, is preferably open upwards in a rest position. The rest position is a position in which the warp beam can be changed. For this purpose, the warp beam can be removed from the torque transmission arrangement upwards without the warp beam having to be displaced in its axial direction. The same applies to inserting the warp beam. Due to the easy handling of the warp beam, the set-up time is reduced, and thus the set-up costs are reduced.
Erfindungsgemäß ist zur Ausbildung einer formschlüssigen Verbindung zwischen der ersten Geometrie und der zweiten Geometrie mindestens ein bewegliches Fixierelement vorgesehen. Das Fixierelement garantiert eine formschlüssige Verbindung zwischen der ersten Geometrie, am Kettbaum, und der zweiten Geometrie, am Antrieb. Durch den Formschluss wird die Drehmomentübertragung sichergestellt, und ein mögliches Spiel zwischen der ersten Geometrie und der zweiten Geometrie reduziert. Ein kleineres Spiel erhöht die Lebensdauer einer solchen Anordnung, was den Wartungsaufwand und somit die Wartungskosten reduziert. Vorzugsweise ist das Fixierelement zwischen einer Drehmomentübertragungsposition und einer Freigabeposition bewegbar. In der Freigabeposition kann der Kettbaum gewechselt werden und in der Drehmomentübertragungsposition wird der Kettbaum angetrieben. In der Freigabeposition besteht keine formschlüssige Verbindung, sodass der Kettbaum entnommen werden kann. Der Kettbaum kann in der Freigabeposition gewechselt werden.According to the invention, at least one movable fixing element is provided to form a positive connection between the first geometry and the second geometry. The fixing element guarantees a positive connection between the first geometry on the warp beam and the second geometry on the drive. The torque transmission is ensured by the form fit and a possible play between the first geometry and the second geometry is reduced. A smaller game increases the service life of such an arrangement, which reduces the maintenance effort and thus the maintenance costs. The fixing element can preferably be moved between a torque transmission position and a release position. The warp beam can be changed in the release position and the warp beam is driven in the torque transmission position. In the release position there is no positive connection, so that the warp beam can be removed. The warp beam can be changed in the release position.
Vorzugsweise ist das Fixierelement in einer axialen Richtung oder einer radialen Richtung des Kettbaums bewegbar. Somit kann eine formschlüssige Verbindung erfolgen, indem das Fixierelement in einer axialen Richtung in die Drehmomentübertragungsposition überführt wird. Alternativ kann der Formschluss durch eine Bewegung des Fixierelements in radialer Richtung in die Drehmomentübertragungsposition erfolgen. Je nach Platzverhältnissen und benötigten Drehmomenten kann eine passende Bewegungsrichtung des Fixierelementes ausgewählt werden. Diese gestalterische Freiheit ermöglicht eine wirtschaftliche, an die Bedingungen angepasste Umsetzung.The fixing element can preferably be moved in an axial direction or in a radial direction of the warp beam. A form-fitting connection can thus take place in that the fixing element is transferred in an axial direction into the torque transmission position. Alternatively, the form fit can be achieved by moving the fixing element in the radial direction into the torque transmission position. Depending on the space available and the torque required, a suitable direction of movement of the fixing element can be selected. This creative freedom enables an economical implementation adapted to the conditions.
Vorzugsweise wird das Fixierelement durch einen Fixiermechanismus betätigt. Um das Fixierelement von der Freigabeposition in die Drehmomentübertragungsposition zu überführen wird der Fixiermechanismus verwendet. Durch den Fixiermechanismus kann der Kettbaum in einer bestimmten Winkelposition freigegeben werden, indem der Fixiermechanismus das Fixierelement in die Freigabeposition bewegt. Dabei kann der Fixiermechanismus einen Servomotor, Pneumatik- oder Hydraulikzylinder oder dergleichen aufweisen. Somit kann der Kettbaum einfach mit geringem Aufwand gewechselt werden, was die Rüstkosten und damit die Gesamtkosten senkt.The fixing element is preferably actuated by a fixing mechanism. The fixing mechanism is used to transfer the fixing element from the release position to the torque transmission position. The warp beam can be released in a specific angular position by the fixing mechanism by the fixing mechanism moving the fixing element to the release position. The fixing mechanism can have a servomotor, pneumatic or hydraulic cylinder or the like. This means that the warp beam can be changed easily with little effort, which reduces set-up costs and thus overall costs.
Vorzugsweise weist der Fixiermechanismus das Fixierelement, eine Fixierelementführung und mindestens einen Hebel auf. Das Fixierelement wird durch die Fixierelementführung geführt, um ein Verkippen des Fixierelementes oder sonstige Störungen zu vermeiden. Durch den Hebel wird die benötigte Kraft zum Bewegen des Fixierelements reduziert. Eine reduzierte Leistung bedeutet, dass eine kleinere Kraft benötigt wird, was geringe laufende Kosten verursacht. Diese Anordnung erhöht dementsprechend die Wirtschaftlichkeit der Kettenwirkmaschine.The fixing mechanism preferably has the fixing element, a fixing element guide and at least one lever. The fixing element is guided through the fixing element guide in order to avoid tilting of the fixing element or other disturbances. The lever reduces the force required to move the fixing element. Reduced performance means less force is required, resulting in low running costs. This arrangement accordingly increases the efficiency of the warp knitting machine.
Vorzugsweise weist der Fixiermechanismus eine Rückstellvorrichtung auf. Durch die Rückstellvorrichtung wird eine ungewollte Bewegung des Fixierelementes vermieden. Die Rückstellvorrichtung erhöht die Betriebssicherheit der Anordnung.The fixing mechanism preferably has a reset device. The resetting device prevents unwanted movement of the fixing element. The reset device increases the operational reliability of the arrangement.
Vorzugsweise weist die Drehmomentübertragungsanordnung eine Sensoranordnung auf. Die Sensoranordnung kann die Position des Fixierelementes und die Winkelposition der Drehmomentübertragungseinrichtung überwachen und weitere sicherheitsrelevante Überwachungsaufgaben übernehmen.The torque transmission arrangement preferably has a sensor arrangement. The sensor arrangement can monitor the position of the fixing element and the angular position of the torque transmission device and can take on other safety-related monitoring tasks.
Vorzugsweise ist die erste Geometrie lösbar an dem freien Ende des Zapfens angeordnet. Die Verbindung zwischen der Geometrie und dem freien Ende des Zapfens kann mittels Befestigungsmitteln, beispielsweise Schrauben oder ähnlichen erfolgen. Durch die lösbare Verbindung kann der Kettbaum an die jeweiligen Bedürfnisse angepasst und bei möglichen Verschleißerscheinungen ausgetauscht werden.Preferably, the first geometry is detachably arranged on the free end of the pin. The connection between the geometry and the free end of the pin can be made by means of fasteners, such as screws or the like. Due to the detachable connection, the warp beam can be adapted to the respective needs and replaced if there are signs of wear.
Alternativ dazu sind die erste Geometrie und das freie Ende des Zapfens einstückig ausgebildet. Eine einstückige Ausbildung reduziert die Anschaffungskosten. Weiterhin wird durch eine einstückige Ausbildung eine hohe Drehmomentübertragungsmöglichkeit erreicht.Alternatively, the first geometry and the free end of the pin are formed in one piece. A one-piece training reduces the acquisition costs. Furthermore, a high torque transmission option is achieved by a one-piece design.
Vorzugsweise ist der Kettbaum werkzeuglos entnehmbar. Ein werkzeugloser Wechsel des Kettbaums reduziert die Rüstzeiten und Rüstkosten. Weiterhin wird durch einen werkzeuglosen Wechsel des Kettbaums der Spielraum für Automatisierungslösungen geöffnet, da kein Bediener mehr gebraucht wird.The warp beam can preferably be removed without tools. A tool-free warp beam change reduces set-up times and set-up costs. Furthermore, the scope for automation solutions is opened up by a tool-free change of the warp beam, since an operator is no longer needed.

Durch das Anbringen des Lagers 3 an den Kettbaum 2, ist es möglich die Lagerschale 5 als halbseitig offene Lagerschale 5 auszuführen. Durch das Gewicht des Kettbaums 2 und die relativ geringen Umfangsgeschwindigkeiten ist die Gefahr des Herausspringens des Kettbaums 2 aus der Lagerschale 5 sehr gering. Somit ist es möglich die Lagerschale 5 ohne Lagerdeckel zu verwenden.By attaching the
In der Ruheposition zeigt die Drehmomentübertragungsanordnung mit der offenen Seite der zweiten Geometrie 7 nach oben. Der Rückstellmechanismus 12 übt eine Kraft aus, die das Fixierelement 9 in die Drehmomentübertragungsposition bewegen will. Der Antrieb 13 wirkt über Hebel 10 dem Rückstellmechanismus 12 entgegen und hält das Fixierelement 9 in der Freigabeposition. Dabei kann der Antrieb 13 als Fluidzylinder, elektrische Motorenanordnung, Zahnrad - Zahnstangen-Anordnungen oder dergleichen ausgebildet sein. Der Kettbaum 2 kann eingelegt werden. Dazu wird das Lager 3 in die Lagerschale 5 eingelegt und die erste Geometrie 4 findet automatisch ihren Platz zu der zweiten Geometrie 7. Liegt der Kettbaum 2 in der Lageranordnung und die erste Geometrie 4 im Bereich der zweiten Geometrie 7, wird durch das Fixierelement 9 ein Formschluss zwischen der ersten Geometrie 4 und der zweiten Geometrie 7 hergestellt. Dazu wird das Fixierelement 9 in die Drehmomentübertragungsposition bewegt. Der Antrieb 13 gibt den Hebel 10 frei und die Kraft des Rückstellmechanismus 12 bewegt das Fixierelement 9 in die Drehmomentübertragungsposition. Das Fixierelement 9 stellt nun eine formschlüssige Verbindung zwischen der ersten Geometrie 4 und der zweiten Geometrie 7 her, ohne dabei die Aufgabe einer Lagerung zu übernehmen. Der Formschluss ist einzig und alleine für die Drehmomentübertragung zuständig. Die Sensoranordnung 14 überwacht derweil, in welcher Position sich das Fixierelement 9 befindet. Diese Überwachung kann die Sensoranordnung 14 entweder direkt am Fixierelement 9 vornehmen, oder indirekt über eine Messung des Hebels 10 oder anderen Elementen, die zur Betätigung des Fixierelementes 9 dienen. Der Kettbaum 2 kann entsprechend der benötigten Bedingungen angetrieben werden.In the rest position, the torque transmission arrangement points with the open side of the
Soll nun der Kettbaum 2 gewechselt werden, wird der Kettbaum 2 und die Drehmomentübertragungsanordnung 8 in die Ruheposition gedreht. Das bedeutet, dass die Geometrieanordnung mit der zweiten Geometrie 7 nach oben hin geöffnet ist. Durch die Sensoranordnung 14 wird eine entsprechende Position erkannt. Anschließend wird das Fixierelement 9 in die Freigabeposition bewegt. Dazu bewegt der Antrieb 13 den Hebel 10 entgegen der Kraft des Rückstellmechanismus 12 und bewegt das Fixierelement in die Freigabeposition. In dieser Freigabeposition besteht kein Formschluss zwischen der ersten Geometrie 4 und der zweiten Geometrie 7. Der Kettbaum 2 kann nach oben entnommen werden, und ein anderer Kettbaum in die Vorrichtung eingelegt werden.If the
