Definitions
- the invention relates to a drafting system for a knitting machine for producing a fiber structure from a roving over Riemchenwalzen guided Doppelriemchen and a pair of output rollers, the Riemchenwalzen and the pair of output rollers each having a pressure roller and an electric motor driven drive roller and the rollers and the electric motors on the front side of a base plate are arranged, while the motor shafts are passed through the base plate and are connected via drive means with the mounted in the base plate axes of the drive rollers.
- Such drafting systems are in the WO 2009/026734 A1 already described. They serve to produce a distorted fiber structure from a roving and to supply it directly to the needles of the knitting machine.
- the knitted fabrics produced from the fiber structure which has essentially parallel aligned fibers, feel considerably softer than knitted pieces produced from a ready-spun yarn. If knitting machines are equipped with such drafting systems, then the process of yarn spinning can be dispensed with.
- the knitwear is made directly from the roving.
- the present invention is therefore based on the object to propose a drafting system for a knitting machine, in which a lower load on the components occurs by fiber fly and is easier to clean.
- a drafting system for a knitting machine for producing a fiber structure from a roving with guided over Riemchenwalzen Doppelriemchen and a pair of output rollers wherein the Riemchenwalzen and the pair of output rollers each have a pressure roller and an electric motor having controlled drive roller and the rollers and the electric motors are arranged on the front side of a base plate, while the motor shafts are passed through the base plate and are connected via drive means with the mounted in the base plate axes of the drive rollers, which is characterized in that on the back of the Base plate a clamping device is provided, with which the pressure rollers of Riemchenwaizencrues and the pair of output rollers are pressed against the drive rollers.
- the tensioning device with which the pressure rollers can be pressed against the driven rollers in order to enable the stretching of the fiber structure, is likewise arranged on the front side above the pressure rollers in the known drafting systems. Since each of the pressure rollers must be acted upon by the clamping device, this has a relatively large number of components which, when arranged on the front of the drafting, d. H. on the side on which the fiber strand passes through, are exposed to fiber fly and thus pollute. They must be cleaned regularly and also make it difficult to clean the pairs of rollers and straps, as they impede free access to them from the top.
- the drafting system according to the invention all components of the tensioning device are arranged on the drafting system rear side, where they can not be contaminated by fiber fly and not block the free access to the roller pairs and straps on the front. As a result, the drafting system according to the invention is much easier to maintain than the known drafting systems.
- the axes of the pressure rollers are guided with clearance through openings in the base plate and from the clamping device in the openings movable up and down. If the tensioning device is relaxed, the rollers can be moved by hand within the scope of the clearance permitted by the openings in order, for example, to exchange and / or to clean a strap or one of the rollers.
- the axes of the pressure rollers are rotatably mounted on the back of the base plate in sliders, wherein the slide can be acted upon by the tensioning device with a spring force.
- the slides which can be mounted in guides, allow precise movement of the pressure roller axes by the spring force generated by the tensioning device, which can be generated by each of the slides associated springs.
- the clamping device has a extending over the slide, slidably disposed on the base plate bar with which the contact pressure can be generated. By simply moving this bar can thereby press the pressure rollers against the drive rollers or relieve.
- the strip can be arranged longitudinally displaceable on the base plate and provided with cams, wherein the cams of the strip act on the springs cooperating with the sliders.
- springs can preferably be used torsion springs. These can be arranged in an adjustable spring block, so that by moving the spring block, the spring force generated by the springs can be adjusted.
- the drafting system according to the invention may also have a pneumatic, hydraulic or electric tensioning device instead of a mechanical tensioning device.
- the tensioning device can be activated and deactivated in a manner known per se by a pivoting lever connected to the tensioning device.
- the pivot lever can be arranged easily accessible outside of the housing of the plate.
- the drafting system can be designed differently. Relatively often so-called 3-roller drafting systems are used, d. H. the drafting system may have, in addition to the Riemchenwalzen and the output roller pair an input roller pair, the pressure roller is also acted upon by the clamping device.
- the motors can be protected by a removable cover against fiber fly.
- a suction can be arranged on the pair of output rollers, with the aid of which fibers and dust can be sucked off before they settle on drafting parts.
- the invention also relates to a knitting machine, preferably a circular knitting machine, which is equipped with at least one drafting device according to the invention.
- the drafting system 10 off Fig. 1 has a base plate 11, on the front side 12, two motors 13, 14, an input roller pair 15, a Riemchenwalzencru 16 and a pair of output rollers 17 are arranged.
- Each of the roller pairs 15, 16, 17 consists of a lower driven roller 15.1, 16.1, 17.1 and an upper pressure roller 15.2, 16.2, 17.2.
- the not shown here, to be forgiven by the drafting 10 fiber structure is in each case between the the upper and lower drive rollers 15.2, 16.2, 17.2 and 15.1, 16.1, 17.1 passed. Due to the different speeds of the roller pairs, the desired stretching of the fiber structure occurs.
- the motors 13, 14 are of an in Fig.1 omitted cover protected from fiber fly.
- a suction is also provided, which was omitted for clarity but also in the figure.
- Fig. 2 shows the back 18 of the base plate 11, on which an electronic control part 19 and a mechanical part 20 of the drafting system 10 are arranged.
- the more detailed structure of the mechanical part 20 is in the Fig. 3 to 6 shown.
- Both the electronic part 19 and the mechanical part 20 are covered by a housing cover to the outside, which are not shown here, however, to share the view of the components of the drafting system 10.
- shafts 13. 1, 14. 1 of the motors 13, 14 are guided through the base plate 11 to the rear side 18. There, via the shaft 13. 1 with the aid of a toothed belt 21, the axis 17. 3 of the output drive roller 17. 1, likewise guided through the base plate 11, is driven.
- the shaft 14.1 drives via a toothed belt 22 and a plurality of pinion shafts 16.3, 15.3 of the belt drive roller 16.1 and the input drive roller 15.1.
- a clamping device 25 for the upper pressure rollers 15.2, 16.2, 17.2 is arranged on the back 18 of the base plate 11. It has a spring block 26 in which three leg springs 27, 28, 29 are mounted. In addition, in the spring block 26th a bar 30 which is connected to a tensioning lever 31, slidably mounted.
- Fig. 5 and Fig. 6 illustrate, are in the sliders 33, 34, 35 each axes 15.4, 16.4, 17.4 of the pressure rollers 15.2, 16.2, 17.2 stored. These axes 15.4, 16.4 and 17.4 are passed through openings 36 in the base plate 19 with play. If the slides 33, 34, 35 are pressed down by the tensioning device 25, the upper pressure rollers 15.2, 16.2, 17.2 also move downwards and thus generate the required contact pressure of the fiber structure against the drive rollers 15.1, 16.1, 17.1. On the other hand, if the tensioning device 25 is inactive ( Fig. 4 ), so the upper pressure rollers 15.2, 16.2, 17.2 can be moved by hand upwards, as far as it allows the game between the axes 15.4, 16.4, 17.4 and the openings 36.

Description
Die Erfindung betrifft ein Streckwerk für eine Strickmaschine zur Herstellung eines Faserverbandes aus einem Vorgarn mit über Riemchenwalzen geführten Doppelriemchen und einem Ausgangswalzenpaar, wobei die Riemchenwalzen und das Ausgangswalzenpaar jeweils eine Druckwalze und eine elektromotorisch gesteuerte Antriebswalze aufweisen und die Walzen und die Elektromotoren auf der Vorderseite einer Grundplatte angeordnet sind, während die Motorwellen durch die Grundplatte hindurchgeführt sind und über Antriebseinrichtungen mit den in der Grundplatte gelagerten Achsen der Antriebswalzen verbunden sind.The invention relates to a drafting system for a knitting machine for producing a fiber structure from a roving over Riemchenwalzen guided Doppelriemchen and a pair of output rollers, the Riemchenwalzen and the pair of output rollers each having a pressure roller and an electric motor driven drive roller and the rollers and the electric motors on the front side of a base plate are arranged, while the motor shafts are passed through the base plate and are connected via drive means with the mounted in the base plate axes of the drive rollers.
Derartige Streckwerke sind in der
Bei den bekannten Streckwerken befinden sich alle Teile, bis auf den Zahnriemenantrieb für die Unterwalzen, auf der Vorderseite der Grundplatte des Streckwerks. Dadurch sind diese Streckwerkteile jedoch auch dem unvermeidlich beim Durchführen des Faserverbandes durch das Streckwerk auftretenden Faserflug ausgesetzt und verschmutzen daher rasch. Durch die Vielzahl von auf der Vorderseite der Grundplatte angebrachten Bauteilen gestaltet sich das Reinigen des Streckwerks jedoch sehr mühsam.In the known drafting systems are all parts, except for the belt drive for the lower rollers, on the front of the base plate of the drafting system. As a result, however, these drafting parts are also exposed to the unavoidable occurring during the passage of the fiber structure by the drafting fiber fly and therefore pollute quickly. Due to the large number of mounted on the front of the base plate components, however, the cleaning of the drafting designed very tedious.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, ein Streckwerk für eine Strickmaschine vorzuschlagen, bei dem eine geringere Belastung der Bauteile durch Faserflug auftritt und das leichter zu reinigen ist.The present invention is therefore based on the object to propose a drafting system for a knitting machine, in which a lower load on the components occurs by fiber fly and is easier to clean.
Die Aufgabe wird gelöst durch ein Streckwerk für eine Strickmaschine zur Herstellung eines Faserverbandes aus einem Vorgarn mit über Riemchenwalzen geführten Doppelriemchen und einem Ausgangswalzenpaar, wobei die Riemchenwalzen und das Ausgangswalzenpaar jeweils eine Druckwalze und eine elektromotorisch gesteuerte Antriebswalze aufweisen und die Walzen und die Elektromotoren auf der Vorderseite einer Grundplatte angeordnet sind, während die Motorwellen durch die Grundplatte hindurchgeführt sind und über Antriebseinrichtungen mit den in der Grundplatte gelagerten Achsen der Antriebswalzen verbunden sind, das dadurch gekennzeichnet ist, dass auf der Rückseite der Grundplatte eine Spanneinrichtung vorgesehen ist, mit der die Druckwalzen des Riemchenwaizenpaares und des Ausgangswalzenpaares gegen die Antriebswalzen anpressbar sind.The object is achieved by a drafting system for a knitting machine for producing a fiber structure from a roving with guided over Riemchenwalzen Doppelriemchen and a pair of output rollers, wherein the Riemchenwalzen and the pair of output rollers each have a pressure roller and an electric motor having controlled drive roller and the rollers and the electric motors are arranged on the front side of a base plate, while the motor shafts are passed through the base plate and are connected via drive means with the mounted in the base plate axes of the drive rollers, which is characterized in that on the back of the Base plate a clamping device is provided, with which the pressure rollers of Riemchenwaizenpaares and the pair of output rollers are pressed against the drive rollers.
Die Spannvorrichtung, mit der die Druckwalzen gegen die angetriebenen Walzen anpressbar sind, um das Verstrecken des Faserverbandes zu ermöglichen, ist bei den bekannten Streckwerken ebenfalls auf der Vorderseite oberhalb der Druckwalzen angeordnet. Da jede der Druckwalzen von der Spanneinrichtung beaufschlagt werden muss, weist diese relativ viele Bauteile auf, die bei Anordnung auf der Vorderseite des Streckwerks, d. h. auf der Seite, auf der der Faserverband durchläuft, Faserflug ausgesetzt sind und damit verschmutzen. Sie müssen regelmäßig gereinigt werden und erschweren außerdem die Reinigung der Walzenpaare und Riemchen, da sie einen freien Zugang zu diesen von der Oberseite her behindern.The tensioning device, with which the pressure rollers can be pressed against the driven rollers in order to enable the stretching of the fiber structure, is likewise arranged on the front side above the pressure rollers in the known drafting systems. Since each of the pressure rollers must be acted upon by the clamping device, this has a relatively large number of components which, when arranged on the front of the drafting, d. H. on the side on which the fiber strand passes through, are exposed to fiber fly and thus pollute. They must be cleaned regularly and also make it difficult to clean the pairs of rollers and straps, as they impede free access to them from the top.
Beim erfindungsgemäßen Streckwerk sind alle Bauteile der Spanneinrichtung auf der Streckwerkrückseite angeordnet, wo sie nicht durch Faserflug verschmutzen können und den freien Zugang zu den Walzenpaaren und Riemchen auf der Vorderseite nicht blockieren. Dadurch ist das erfindungsgemäße Streckwerk deutlich wartungsfreundlicher als die bekannten Streckwerke.In the drafting system according to the invention all components of the tensioning device are arranged on the drafting system rear side, where they can not be contaminated by fiber fly and not block the free access to the roller pairs and straps on the front. As a result, the drafting system according to the invention is much easier to maintain than the known drafting systems.
Bei einer bevorzugten Ausgestaltung des Streckwerks sind die Achsen der Druckwalzen mit Spiel durch Öffnungen in der Grundplatte geführt und von der Spanneinrichtung in den Öffnungen auf und ab bewegbar. Wird die Spanneinrichtung entspannt, können die Walzen von Hand im Rahmen des durch die Öffnungen erlaubten Spiels bewegt werden, um beispielsweise ein Riemchen oder eine der Walzen austauschen und/oder reinigen zu können.In a preferred embodiment of the drafting system, the axes of the pressure rollers are guided with clearance through openings in the base plate and from the clamping device in the openings movable up and down. If the tensioning device is relaxed, the rollers can be moved by hand within the scope of the clearance permitted by the openings in order, for example, to exchange and / or to clean a strap or one of the rollers.
Dabei ist es von Vorteil, wenn die Achsen der Druckwalzen auf der Rückseite der Grundplatte in Schiebern drehbar gelagert sind, wobei die Schieber von der Spanneinrichtung mit einer Federkraft beaufschlagbar sind. Die Schieber, die in Führungen gelagert sein können, erlauben ein präzises Bewegen der Druckwalzenachsen durch die von der Spanneinrichtung erzeugte Federkraft, wobei diese durch jedem der Schieber zugeordnete Federn erzeugt werden kann.It is advantageous if the axes of the pressure rollers are rotatably mounted on the back of the base plate in sliders, wherein the slide can be acted upon by the tensioning device with a spring force. The slides, which can be mounted in guides, allow precise movement of the pressure roller axes by the spring force generated by the tensioning device, which can be generated by each of the slides associated springs.
Bei dieser Ausgestaltung der Spanneinrichtung ist es weiter vorteilhaft, wenn die Spanneinrichtung eine sich über die Schieber erstreckende, verschiebbar an der Grundplatte angeordnete Leiste aufweist, mit der die Anpresskraft erzeugbar ist. Durch einfaches Verschieben dieser Leiste lassen sich dadurch die Druckwalzen gegen die Antriebswalzen anpressen oder entlasten. Die Leiste kann dazu längs verschiebbar an der Grundplatte angeordnet und mit Nocken versehen sein, wobei die Nocken der Leiste auf die mit den Schiebern zusammenwirkende Federn einwirken. Als Federn lassen sich vorzugsweise Schenkelfedern einsetzen. Diese können in einem verstellbaren Federblock angeordnet sein, sodass durch Verschieben des Federblocks die durch die Federn erzeugte Federkraft eingestellt werden kann.In this embodiment of the clamping device, it is also advantageous if the clamping device has a extending over the slide, slidably disposed on the base plate bar with which the contact pressure can be generated. By simply moving this bar can thereby press the pressure rollers against the drive rollers or relieve. The strip can be arranged longitudinally displaceable on the base plate and provided with cams, wherein the cams of the strip act on the springs cooperating with the sliders. As springs can preferably be used torsion springs. These can be arranged in an adjustable spring block, so that by moving the spring block, the spring force generated by the springs can be adjusted.
Das erfindungsgemäße Streckwerk kann jedoch anstelle einer mechanischen Spanneinrichtung auch eine pneumatische, hydraulische oder elektrische Spanneinrichtung aufweisen.However, the drafting system according to the invention may also have a pneumatic, hydraulic or electric tensioning device instead of a mechanical tensioning device.
Die Spanneinrichtung kann dabei in an sich bekannter Weise durch einen mit der Spanneinrichtung verbundenen Schwenkhebel aktiviert und deaktiviert werden. Der Schwenkhebel lässt sich dabei leicht zugänglich außerhalb des Gehäuses der Platte anordnen.The tensioning device can be activated and deactivated in a manner known per se by a pivoting lever connected to the tensioning device. The pivot lever can be arranged easily accessible outside of the housing of the plate.
Je nach zu verarbeitendem Vorgarn kann das Streckwerk unterschiedlich ausgestaltet sein. Relativ häufig werden sogenannte 3-Walzen-Streckwerke eingesetzt, d. h. das Streckwerk kann zusätzlich zu den Riemchenwalzen und dem Ausgangswalzenpaar ein Eingangswalzenpaar aufweisen, dessen Druckwalze ebenfalls von der Spanneinrichtung beaufschlagbar ist.Depending on the roving to be processed, the drafting system can be designed differently. Relatively often so-called 3-roller drafting systems are used, d. H. the drafting system may have, in addition to the Riemchenwalzen and the output roller pair an input roller pair, the pressure roller is also acted upon by the clamping device.
Als weitere Maßnahme zur Reduzierung der Verschmutzung des Streckwerks durch Faserflug können die Motoren von einer abnehmbaren Abdeckung gegen Faserflug geschützt sein. Außerdem kann am Ausgangswalzenpaar eine Absaugung angeordnet sein, mit deren Hilfe Fasern und Staub abgesaugt werden können, bevor sie sich auf Streckwerkteilen absetzen.As a further measure to reduce fouling of the drafting system by fiber fly, the motors can be protected by a removable cover against fiber fly. In addition, a suction can be arranged on the pair of output rollers, with the aid of which fibers and dust can be sucked off before they settle on drafting parts.
Auch wenn die Streckwerkrückseite nicht direkt mit dem Faserverband in Berührung kommt, ist es weiter zweckmäßig auch die Rückseite der Grundplatte durch einen abnehmbaren Gehäusedeckel zu schützen.Even if the drafting rear side does not come into direct contact with the fiber structure, it is also expedient to protect the rear side of the base plate by a removable housing cover.
Die Erfindung betrifft außerdem eine Strickmaschine, vorzugsweise eine Rundstrickmaschine, die mit mindestens einem erfindungsgemäßen Streckwerk ausgerüstet ist.The invention also relates to a knitting machine, preferably a circular knitting machine, which is equipped with at least one drafting device according to the invention.
Nachfolgend wird ein bevorzugtes Ausführungsbeispiel eines erfindungsgemäßen Streckwerks mit Bezug auf die Zeichnung näher beschrieben.Hereinafter, a preferred embodiment of a drafting system according to the invention will be described in more detail with reference to the drawing.
