Definitions
- the invention relates to a work station of a textile machine with a spinning station and a drafting system according to the preamble of claim 1.
- Such a job is, for example, from the documents JP H05 19365 U , DE 43 18 025 A1 and DE 102 43 800 A1 previously known.
- drafting systems for textile machines are known in various designs from the prior art. They serve to stretch or distort a sliver, thereby reducing the cross-section of the fiber. During the draft, the fibers must be moved as evenly as possible against each other in order to achieve a sliver that is as uniform as possible.
- the drafting systems usually have several pairs of rollers arranged one after the other, which, arranged next to one another, clamp the sliver running between them.
- a pair of rollers usually consists of a driven lower roller and an upper pressure roller resting on the lower roller, which is rotatably held by a load carrier.
- a distortion of the sliver is achieved by the fact that in the transport direction of the sliver determined by the direction of rotation of the pairs of rollers, the peripheral speed increases from pair of rollers to pair of rollers.
- the load carrier of the type mentioned at the beginning serves to press the upper pressure roller or upper roller arranged on the load carrier against the assigned lower roller with a predefined pressure, so that the upper roller rests under pressure on the corresponding lower roller in the operating position.
- a drafting unit for a textile machine of the type mentioned at the beginning is an assembly of a drafting unit of a textile machine, whereby the drafting unit can also be designed as a complete drafting unit depending on its design.
- Known textile machines have one workstation for each sliver to be stretched separate drafting system with several pairs of rollers arranged in rows, to which a load carrier is assigned.
- the document DE 10 2006 029 132 A1 discloses a drafting system with two load carriers with upper rollers in between.
- the drafting systems are usually integrated into the textile machines in such a way that only wearing parts can be serviced and, if necessary, replaced in a user-friendly manner.
- the invention is based on the object of providing a drafting unit for stretching a sliver at a workstation of a textile machine, which can be inspected, repaired and/or adapted to the sliver material to be stretched in a user-friendly manner.
- the textile machine is preferably a spinning machine that stretches a sliver, such as a ring spinning machine, a flyer, an air-jet spinning machine or similar.
- the support frame has a coupling section and a locking unit for releasably connecting the support frame to the assigned work location.
- the design of the support frame with a coupling section and a locking unit makes it possible to conveniently arrange the support frame in a modular manner on the textile machine and to precisely position and fix it in an operating position via the locking unit. By unlocking the locking unit, the drafting unit can be conveniently removed from the textile machine or the workstation if necessary.
- the support frame is in engagement with corresponding receiving sections on the textile machine or the workstation via the coupling section and the locking unit.
- the locking unit ensures a secure positioning of the top roller, which has at least one top roller and is pivotably mounted on the support frame Load carrier, which ensures reliable operation of a drafting system having this drafting unit.
- Maintenance and adjustment work as well as adjustments of the pressure rollers to the sliver material to be stretched on the load carrier can be carried out in a comfortable manner at suitable workplaces after it has been easily removed.
- support frame or the drafting system unit comprising such a support frame can be exchanged in a simple and cost-effective manner for new, adapted or further developed support frames or drafting system units, so that, for example, existing drafting systems can also be improved by simply replacing further developed drafting system units.
- the arrangement of the drafting unit on the textile machine or at the workstation and the removal of the drafting unit from it can basically be done in any way.
- an embodiment is conceivable in which the support frame or the drafting unit unit is arranged linearly between a release position in which the drafting unit can be arranged on the textile machine and removed from it, and an operating position in which the support frame or the drafting unit is arranged, if the assigned drafting system is in operation and can be adjusted.
- the coupling section is to be arranged on a receiving section of the textile machine or the workstation for adjusting the support frame between a release position in which the support frame or the drafting unit can be removed from the assigned workstation, and an operating position in which the Support frame or the drafting unit is arranged in a secure position at the assigned workstation for operation of a load carrier mounted on the support frame.
- the support frame is first arranged for assembly on a correspondingly designed receiving section of the textile machine. From this release position, the support frame is adjusted into the operating position via a corresponding design of the coupling section, regardless of the design of the receiving section, in which the drafting unit is then secured in position on the textile machine or the workstation via the locking unit.
- This configuration of the coupling section for adjusting the support frame between the release and the operating position allows for a corresponding adaptation of the textile machine or the workstation to the coupling section, or to a special one Design of the receiving section taking into account the shape of the coupling section.
- a basic adjustment possibility of the support frame exists due to the design of the coupling section, which primarily ensures sufficient support of the drafting unit on the textile machine via the receiving section.
- a possible preferred embodiment of this development of the invention provides, for example, that the coupling section is connected in an articulated manner to the support frame, so that the adjustment is realized independently of the design of the receiving section by a corresponding design of the support frame.
- the coupling section has a recess adapted to a receiving section, in particular a frame support of the textile machine.
- This configuration enables a particularly simple and cost-effective construction and production of the support frame, with an advantageously cylindrical configuration of the frame support with a corresponding design of the recess enabling a particularly simple adjustability of the drafting unit between the release position and the operating position.
- the advantageously provided recess for arranging the support frame or the drafting unit on the frame support can in principle be formed by any elements, for example flanges arranged on the support frame can be provided for this purpose, which are provided with corresponding recesses. According to a particularly advantageous embodiment of the invention, however, it is provided that the recess is formed in one piece with the support frame. Forming the recess on the support frame makes it possible to dispense with additional components, which means that the manufacturing costs for the support frame can be reduced in a complementary manner.
- the one-piece design of the recess on the support frame offers a weight advantage compared to the use of additional components and recesses.
- the design of the locking unit for fixing the support frame or the drafting unit in the operating position on the textile machine or the workstation can basically done in any way. It is conceivable, for example, to use magnetically or electrically acting locking elements on the support frame, which interact with corresponding components on the textile machine in the operating position. According to the invention it is provided that the locking unit has a locking body which is adjustable between an opening and a locking position and can be brought into engagement with a locking receptacle on the textile machine in an operating position of the support frame.
- Such a design of the locking unit has a particularly simple and therefore cost-effective and error-prone structure.
- a locking body on the locking unit of the support frame is adjustable between the opening and the locking position, with the locking body in the locking position being in engagement with a corresponding locking receptacle on the textile machine. In this position, the positive connection created via the locking body and locking receptacle ensures that the position of the support frame or the drafting unit on the textile machine is reliably secured.
- a simple displacement of the locking body from the locking receptacle is sufficient to move the support frame from the operating position to the release position.
- the design of the locking body and the corresponding design of the locking receptacle are fundamentally freely selectable.
- locking hooks that can be brought into engagement with corresponding locking holes or bolts that are gripped by the locking hook can be used.
- the locking body can also be designed as a displaceable locking bolt, which engages in a corresponding locking bolt receptacle in the locking position.
- the locking body is biased towards the locking position.
- a corresponding embodiment of the invention ensures that the drafting unit is automatically locked in the operating position by the locking body prestressed to the locking position after a shift from the release to the operating position. Incorrect operation or a failure to lock due to an operating error are thus reliably avoided. If the support frame needs to be removed, it is only necessary to move the locking body into the open position against the preload, so that the support frame can then be easily adjusted from the operating to the release position and then removed from the textile machine.
- the support frame has at least one bearing point for pivotally supporting a load carrier assigned to the drafting unit, which can hold at least one top roller in a rotatable manner.
- the support frame is designed to accommodate at least one additional unit, in particular for arranging a drive unit of a lower roller arranged on the support frame according to an advantageous development of the invention, a communication unit and / or a control device of the drive unit.
- a further preferred embodiment of the support frame with a fastening rail for receiving the at least one additional unit offers the possibility of arranging and adjusting the at least one additional unit on the support frame in a simple manner, for example via a standardized design of the fastening rail, and also from it again to remove.
- the resulting greater flexibility enables cost-effective maintenance and, if necessary, easy replacement of individual additional units, which can also be the lower rollers assigned to the upper rollers.
- a connection of the drafting unit, in particular one or more electronic units arranged on the support frame, to an associated control unit can be established in a simple manner via a cable connection or alternatively via a communication unit which is designed for wireless data transmission.
- Data transmission can take place with a control device of the workstation, a central control device of the entire textile machine or a higher-level control device that controls several textile machines.
- two bearing points are provided on the support frame, each for pivotally supporting a load carrier, the load carriers being designed in particular to support at least one top roller between the load carriers.
- the arrangement of the upper roller between the load carriers enables a particularly uniform transfer of the pressure of the upper roller to the assigned lower roller, since the loading force acts on the upper roller on both sides and not in the middle on the web running between two top rollers.
- a more uniform pressure distribution ensures in a particularly advantageous manner that the fibers are moved evenly against one another during the draft, so that a particularly uniform sliver can be produced.
- the support frame has a handling element, in particular a handle element.
- a handling element which can, for example, also be designed to accommodate suitable handling tools, makes it possible to easily remove the support frame from the textile machine or the workstation or to arrange it there.
- the handling element is designed as a grip element, which enables the operator to grip the support frame in a particularly reliable manner and also to adjust it between the operating and release positions.
- the arrangement of one or more handle elements can take into account the operating forces that occur in order to enable easier operation.
- the drafting system unit which has a load carrier having at least one top roller, is that the drafting system unit has a support frame according to one of the embodiments described above, on which the load carrier is pivotally mounted.
- a correspondingly designed drafting system is characterized in that, depending on the assemblies of the drafting system unit arranged on the support frame, they can be arranged on the textile machine in a simple and comfortable manner and can also be removed from it again. This makes it possible to carry out maintenance and repair work as well as adjustment and adjustment work in a comfortable manner at a separate workstation, away from the textile machine, where there is good access to all assemblies of the drafting unit. Above all, the drafting unit can be installed and removed again in a particularly time-saving manner, which means that cleaning work can be carried out more quickly and therefore downtimes of the textile machine can be reduced.
- the drafting system can also be replaced in a simple manner, meaning that the appropriately trained personnel that would otherwise be required for this can be dispensed with.
- two load carriers with at least one intermediate top roller are arranged on the support frame according to an exemplary embodiment described above, the two load carriers being connectable or connected to one another via a handle element.
- the grip element can extend in particular parallel to the top roller from one load carrier to the other load carrier or can be arranged and releasably fastened to the load carriers in such a way.
- Such a common handle element makes it possible to remove the drafting unit or the drafting system from the textile machine or the workstation in a reduced and simple manner and to arrange the same at the workstation or the textile machine.
- the detachable arrangement and fastening of the handle element enables a further reduction in components.
- a handle element can be carried by the operator and, in the event of measures being taken, can be arranged and attached to the drafting system. Such an attachment can be done in the usual way in a positive or non-positive manner.
- the common handle element enables the load carriers in the operating position of the support frame to move together in the usual way into a position spaced apart from the lower rollers in order to carry out measures such as cleaning one or more of the upper and / or lower rollers or other measures that do not require removal of the drafting unit or the drafting system from the textile machine or the workstation, can be pivoted, which can further simplify handling.
- the drafting system is designed as a drafting system module that can be arranged and removed at the work site.
- at least the at least one load carrier with the at least one upper roller, a lower roller assigned to the at least one upper roller and a drive which rotates the lower roller and which can be connected to a control device in a wired or wireless manner are arranged on the support frame in a manner as described above as an example.
- the control device for driving the lower roller can preferably be arranged on the support frame and in particular connected to the drive.
- a sliver (not shown here) fed to the drafting system 2 is stretched between a total of four roller drives, each consisting of an upper roller 7 and an associated lower roller, and fed to a spinneret 10 of the spinning station 1.
- the lower rollers driven by individual drives 8 and the upper rollers 7 arranged on two parallel load carriers 6 are arranged on a support frame 3, the load carriers 6 being pivotally connected to the support frame 3.
- the support frame 3 has two side elements 15, each of which has a recess 5.
- the drafting system 2 shown in a dismantled position is first arranged in a release position on the textile machine, in which recesses 5 of the support frame 3 are placed on a support tube 4 of the textile machine that forms a receiving section.
- the drafting system 2 is moved from this release position by a pivoting movement of the drafting system 2 around the support tube 4 into the Figures 1 and 3 shown operating position of the drafting system 2 adjusted.
- the drafting system 2 is aligned with respect to the spinning station 1 via the locking hooks 12 and the locking hook receptacle 13 in such a way that a stretched sliver from the drafting system 2 reliably reaches the spinneret 10 of the spinning station 1.
- a control device 11 is arranged on the underside of the support frame 3, the control device 11 being mounted in a linearly displaceable manner on the support frame 3 on a guide rail (not shown here) which is fixed to the side elements 15 via fastening holes 16.
- the load carriers 6, which are arranged at a distance from one another, each serve together to support the upper rollers 7 between the load carriers 6, so that the upper rollers 7 are pressed against the lower rollers with a uniform loading force, which are each driven via individual drives 8.
- a handle 9 is arranged on the load carriers 6, which also allows the load carriers 6 to be pivoted relative to the lower rollers after a previous unlocking.
Description
Die Erfindung betrifft eine Arbeitsstelle einer Textilmaschine mit einer Spinnstelle und einem Streckwerk gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a work station of a textile machine with a spinning station and a drafting system according to the preamble of
Eine solche Arbeitsstelle ist beispielsweise aus den Dokumenten
Ferner sind Streckwerke für Textilmaschinen in vielfältigen Ausgestaltungen aus dem Stand der Technik bekannt. Sie dienen dazu, ein Faserband zu verstrecken bzw. zu verziehen, wodurch eine Querschnittsreduzierung der Faser bewirkt wird. Während des Verzugs müssen die Fasern möglichst gleichmäßig gegeneinander verschoben werden, um ein möglichst gleichmäßiges Faserband zu erreichen.Furthermore, drafting systems for textile machines are known in various designs from the prior art. They serve to stretch or distort a sliver, thereby reducing the cross-section of the fiber. During the draft, the fibers must be moved as evenly as possible against each other in order to achieve a sliver that is as uniform as possible.
Zur Verstreckung des Faserbandes weisen die Streckwerke in der Regel mehrere nacheinander angeordnete Walzenpaare auf, die aneinander liegend angeordnet das zwischen ihnen verlaufende Faserband einklemmen. Ein Walzenpaar besteht dabei üblicherweise aus einer angetriebenen Unterwalze und einer an der Unterwalze anliegenden oberen Druckwalze, welche von einem Belastungsträger drehbar gehalten wird. Ein Verzug des Faserbandes wird dadurch erreicht, dass in der durch die Drehrichtung der Walzenpaare festgelegten Transportrichtung des Faserbandes die Umfangsgeschwindigkeit von Walzenpaar zu Walzenpaar zunimmt.To stretch the sliver, the drafting systems usually have several pairs of rollers arranged one after the other, which, arranged next to one another, clamp the sliver running between them. A pair of rollers usually consists of a driven lower roller and an upper pressure roller resting on the lower roller, which is rotatably held by a load carrier. A distortion of the sliver is achieved by the fact that in the transport direction of the sliver determined by the direction of rotation of the pairs of rollers, the peripheral speed increases from pair of rollers to pair of rollers.
Bei einer Streckwerkeinheit dient der Belastungsträger der eingangs genannten Art dazu, die an dem Belastungsträger angeordnete obere Druckwalze bzw. Oberwalze mit einem vordefinierten Druck an die zugeordnete Unterwalze anzudrücken, sodass die Oberwalze in der Betriebsposition druckbelastet auf der entsprechenden Unterwalze aufliegt. Bei einer Streckwerkeinheit für eine Textilmaschine der eingangs genannten Art handelt es sich um eine Baugruppe eines Streckwerks einer Textilmaschine, wobei die Streckwerkeinheit in Abhängigkeit von deren Ausgestaltung auch als vollständiges Streckwerk ausgebildet sein kann.In a drafting unit, the load carrier of the type mentioned at the beginning serves to press the upper pressure roller or upper roller arranged on the load carrier against the assigned lower roller with a predefined pressure, so that the upper roller rests under pressure on the corresponding lower roller in the operating position. A drafting unit for a textile machine of the type mentioned at the beginning is an assembly of a drafting unit of a textile machine, whereby the drafting unit can also be designed as a complete drafting unit depending on its design.
Bekannte Textilmaschinen weisen pro Arbeitsstelle für jedes zu verstreckende Faserband ein separates Streckwerk mit mehreren in Reihen angeordneten Walzenpaaren auf, denen ein Belastungsträger zugeordnet ist. Das Dokument
Instandhaltungs- und Instandsetzungsarbeiten, wie bspw. die Durchführung weitergehender Reinigungen, regelmäßige Inspektionen oder die Ermittlung einer Störungsursache sowie die Anpassung der Walzenpaare an das zu verziehende Garnmaterial müssen im eingebauten Zustand des Streckwerks an der Textilmaschine vorgenommen werden, wobei benachbarte Arbeitsstellen und angrenzende Aggregate derartige Arbeiten erschweren.Maintenance and repair work, such as carrying out further cleaning, regular inspections or determining the cause of a malfunction as well as adapting the roller pairs to the yarn material to be drawn must be carried out with the drafting system on the textile machine installed, with neighboring work stations and adjacent units carrying out such work complicate.
Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde, eine Streckwerkeinheit zum Verstrecken eines Faserbandes an einer Arbeitsstelle einer Textilmaschine bereitzustellen, die in benutzerfreundlicher Weise insbesondere inspiziert, instandgesetzt und/oder an das zu verstreckende Faserbandmaterial angepasst werden kann.Proceeding from this, the invention is based on the object of providing a drafting unit for stretching a sliver at a workstation of a textile machine, which can be inspected, repaired and/or adapted to the sliver material to be stretched in a user-friendly manner.
Die Erfindung löst die Aufgabe mit den Merkmalen des Anspruchs 1. Vorteilhafte Weiterbildungen der Arbeitsstelle sind in den abhängigen Ansprüchen angegeben. Bei der Textilmaschine handelt es sich vorzugsweise um eine ein Faserband verstreckende Spinnmaschine wie eine Ringspinnmaschine, einen Flyer, eine Luftspinnmaschine oder ähnliche. Der Tragrahmen weist einen Kopplungsabschnitt und eine Arretierungseinheit zur lösbaren Verbindung des Tragrahmens an der zugeordneten Arbeitsstelle aufweist. Die Ausgestaltung des Tragrahmens mit einem Kopplungsabschnitt und einer Arretierungseinheit ermöglicht es, den Tragrahmen in komfortabler Weise an der Textilmaschine modular anzuordnen und über die Arretierungseinheit in einer Betriebsposition exakt zu positionieren und zu fixieren. Durch eine Entriegelung der Arretierungseinheit kann die Streckwerkeinheit im Bedarfsfall in komfortabler Weise von der Textilmaschine bzw. der Arbeitsstelle entfernt bzw. abgenommen werden.The invention solves the problem with the features of
Der Tragrahmen ist dabei über den Kopplungsabschnitt und die Arretierungseinheit mit entsprechenden Aufnahmeabschnitten an der Textilmaschine bzw. der Arbeitsstelle in Eingriff. In der Betriebsposition gewährleistet die Arretierungseinheit eine lagesichere Anordnung des mindestens eine Oberwalze aufweisenden, an dem Tragrahmen schwenkbar gelagerten Belastungsträgers, wodurch ein zuverlässiger Betrieb eines diese Streckwerkeinheit aufweisenden Streckwerks gewährleistet ist. Wartungs- und Einstellarbeiten als auch Anpassungen der Druckwalzen an das zu verstreckende Faserbandmaterial an dem Belastungsträger lassen sich nach dessen einfacher Entnahme in komfortabler Weise an geeigneten Arbeitsplätzen durchführen. Darüber hinaus lässt sich der Tragrahmen bzw. die einen solchen Tragrahmen umfassende Streckwerkeinheit in einfacher und kostengünstiger Weise gegen neue, angepasste oder weiterentwickelte Tragrahmen bzw. Streckwerkeinheiten austauschen, sodass beispielsweise auch bestehende Streckwerke über lediglich einen Austausch weiterentwickelter Streckwerkeinheiten verbessert werden können.The support frame is in engagement with corresponding receiving sections on the textile machine or the workstation via the coupling section and the locking unit. In the operating position, the locking unit ensures a secure positioning of the top roller, which has at least one top roller and is pivotably mounted on the support frame Load carrier, which ensures reliable operation of a drafting system having this drafting unit. Maintenance and adjustment work as well as adjustments of the pressure rollers to the sliver material to be stretched on the load carrier can be carried out in a comfortable manner at suitable workplaces after it has been easily removed. In addition, the support frame or the drafting system unit comprising such a support frame can be exchanged in a simple and cost-effective manner for new, adapted or further developed support frames or drafting system units, so that, for example, existing drafting systems can also be improved by simply replacing further developed drafting system units.
Die Anordnung der Streckwerkeinheit an der Textilmaschine bzw. an der Arbeitsstelle sowie die Entnahme der Streckwerkeinheit von dieser können grundsätzlich in beliebiger Weise erfolgen. Denkbar ist beispielsweise eine Ausgestaltung, bei welcher der Tragrahmen bzw. die Streckwerkeinheit linear zwischen einer Freigabeposition, in der die Streckwerkeinheit an der Textilmaschine angeordnet und von dieser entnommen werden kann, und einer Betriebsposition, in welcher der Tragrahmen bzw. die Streckwerkeinheit angeordnet ist, wenn das zugeordnete Streckwerk im Betrieb befindlich ist, verstellt werden kann.The arrangement of the drafting unit on the textile machine or at the workstation and the removal of the drafting unit from it can basically be done in any way. For example, an embodiment is conceivable in which the support frame or the drafting unit unit is arranged linearly between a release position in which the drafting unit can be arranged on the textile machine and removed from it, and an operating position in which the support frame or the drafting unit is arranged, if the assigned drafting system is in operation and can be adjusted.
Nach der Erfindung ist vorgesehen, dass der Kopplungsabschnitt zur Anordnung an einem Aufnahmeabschnitt der Textilmaschine bzw. der Arbeitsstelle zur Verstellung des Tragrahmens zwischen einer Freigabeposition, in welcher der Tragrahmen bzw. die Streckwerkeinheit von der zugeordneten Arbeitsstelle entnehmbar ist, und einer Betriebsposition, in welcher der Tragrahmen bzw. die Streckwerkeinheit an der zugeordneten Arbeitsstelle für einen Betrieb eines an dem Tragrahmen gelagerten Belastungsträgers lagesicher angeordnet ist, ausgebildet ist. Gemäß dieser Ausgestaltung der Erfindung ist vorgesehen, dass der Tragrahmen zur Montage zunächst an einem entsprechend ausgebildeten Aufnahmeabschnitt der Textilmaschine angeordnet wird. Von dieser Freigabeposition erfolgt über eine entsprechende Ausgestaltung des Kopplungsabschnitts, unabhängig von der Ausgestaltung des Aufnahmeabschnitts, eine Verstellung des Tragrahmens in die Betriebsposition, in der die Streckwerkeinheit dann über die Arretierungseinheit an der Textilmaschine bzw. der Arbeitsstelle lagegesichert ist.According to the invention it is provided that the coupling section is to be arranged on a receiving section of the textile machine or the workstation for adjusting the support frame between a release position in which the support frame or the drafting unit can be removed from the assigned workstation, and an operating position in which the Support frame or the drafting unit is arranged in a secure position at the assigned workstation for operation of a load carrier mounted on the support frame. According to this embodiment of the invention, it is provided that the support frame is first arranged for assembly on a correspondingly designed receiving section of the textile machine. From this release position, the support frame is adjusted into the operating position via a corresponding design of the coupling section, regardless of the design of the receiving section, in which the drafting unit is then secured in position on the textile machine or the workstation via the locking unit.
Diese Ausgestaltung des Kopplungsabschnitts zur Verstellung des Tragrahmens zwischen der Freigabe- und der Betriebsposition erlaubt es, auf eine entsprechende Anpassung der Textilmaschine bzw. der Arbeitsstelle an den Kopplungsabschnitt, bzw. auf eine spezielle Ausgestaltung des Aufnahmeabschnitts unter Berücksichtigung der Form des Kopplungsabschnitts zu verzichten. Eine grundsätzliche Verstellmöglichkeit des Tragrahmens besteht gemäß dieser Ausgestaltung der Erfindung bereits aufgrund der Ausgestaltung des Kopplungsabschnitts, welcher vordringlich eine ausreichende Abstützung der Streckwerkeinheit an der Textilmaschine über den Aufnahmeabschnitt gewährleistet. Eine mögliche bevorzugte Ausgestaltung dieser Weiterbildung der Erfindung sieht bspw. vor, dass der Kopplungsabschnitt gelenkig mit dem Tragrahmen verbunden ist, sodass die Verstellung unabhängig von der Ausgestaltung des Aufnahmeabschnitts durch eine entsprechende Ausgestaltung des Tragrahmens realisiert wird.This configuration of the coupling section for adjusting the support frame between the release and the operating position allows for a corresponding adaptation of the textile machine or the workstation to the coupling section, or to a special one Design of the receiving section taking into account the shape of the coupling section. According to this embodiment of the invention, a basic adjustment possibility of the support frame exists due to the design of the coupling section, which primarily ensures sufficient support of the drafting unit on the textile machine via the receiving section. A possible preferred embodiment of this development of the invention provides, for example, that the coupling section is connected in an articulated manner to the support frame, so that the adjustment is realized independently of the design of the receiving section by a corresponding design of the support frame.
Wie bereits vorstehend dargelegt, ist die grundsätzliche Ausgestaltung der Verbindung des Tragrahmens bzw. der Streckwerkeinheit über den Kopplungsabschnitt mit dem Aufnahmeabschnitt an der Textilmaschine grundsätzlich frei wählbar. Nach der Ausgestaltung der Erfindung ist vorgesehen, dass der Kopplungsabschnitt eine an einen Aufnahmeabschnitt, insbesondere eine Rahmenstütze der Textilmaschine angepasste Aussparung aufweist. Diese Ausgestaltung ermöglicht eine besonders einfache und kostengünstige Konstruktion und Herstellung des Tragrahmens, wobei eine vorteilhafterweise zylindrische Ausgestaltung der Rahmenstütze bei einer entsprechenden Ausgestaltung der Aussparung eine besonders einfache Verstellbarkeit der Streckwerkeinheit zwischen der Freigabeposition und der Betriebsposition ermöglicht.As already explained above, the basic design of the connection of the support frame or the drafting unit via the coupling section with the receiving section on the textile machine is fundamentally freely selectable. According to the embodiment of the invention, it is provided that the coupling section has a recess adapted to a receiving section, in particular a frame support of the textile machine. This configuration enables a particularly simple and cost-effective construction and production of the support frame, with an advantageously cylindrical configuration of the frame support with a corresponding design of the recess enabling a particularly simple adjustability of the drafting unit between the release position and the operating position.
Die vorteilhafterweise vorgesehene Aussparung zur Anordnung des Tragrahmens bzw. der Streckwerkeinheit an der Rahmenstütze kann grundsätzlich durch beliebige Elemente gebildet werden, beispielsweise können hierfür an dem Tragrahmen angeordnete Flansche vorgesehen sein, welche mit entsprechenden Aussparungen versehen sind. Nach einer besonders vorteilhaften Ausgestaltung der Erfindung ist jedoch vorgesehen, dass die Aussparung einstückig mit dem Tragrahmen ausgebildet ist. Eine Ausbildung der Aussparung an dem Tragrahmen erlaubt es, auf zusätzliche Bauteile zu verzichten, wodurch sich die Herstellungskosten für den Tragrahmen in ergänzender Weise reduzieren lassen. Darüber hinaus bietet die einstückige Ausgestaltung der Aussparung an dem Tragrahmen gegenüber die Verwendung ergänzender Bauteile und Aussparungen einen Gewichtsvorteil.The advantageously provided recess for arranging the support frame or the drafting unit on the frame support can in principle be formed by any elements, for example flanges arranged on the support frame can be provided for this purpose, which are provided with corresponding recesses. According to a particularly advantageous embodiment of the invention, however, it is provided that the recess is formed in one piece with the support frame. Forming the recess on the support frame makes it possible to dispense with additional components, which means that the manufacturing costs for the support frame can be reduced in a complementary manner. In addition, the one-piece design of the recess on the support frame offers a weight advantage compared to the use of additional components and recesses.
Die Ausgestaltung der Arretierungseinheit zur Festlegung des Tragrahmens bzw. der Streckwerkeinheit in der Betriebsposition an der Textilmaschine bzw. der Arbeitsstelle kann grundsätzlich in beliebiger Weise erfolgen. Denkbar ist beispielsweise die Verwendung von magnetisch oder elektrisch wirkenden Arretierungselementen an dem Tragrahmen, welche in der Betriebsposition mit entsprechenden Bauteilen an der Textilmaschine zusammenwirken. Nach der Erfindung ist vorgesehen, dass die Arretierungseinheit einen zwischen einer Öffnungs- und einer Verriegelungsstellung verstellbaren, in einer Betriebsposition des Tragrahmens mit einer Rastaufnahme an der Textilmaschine in Eingriff bringbaren Rastkörper aufweist.The design of the locking unit for fixing the support frame or the drafting unit in the operating position on the textile machine or the workstation can basically done in any way. It is conceivable, for example, to use magnetically or electrically acting locking elements on the support frame, which interact with corresponding components on the textile machine in the operating position. According to the invention it is provided that the locking unit has a locking body which is adjustable between an opening and a locking position and can be brought into engagement with a locking receptacle on the textile machine in an operating position of the support frame.
Eine derartige Ausgestaltung der Arretierungseinheit weist einen besonders einfachen und somit kostengünstigen sowie fehlerunanfälligen Aufbau auf. Ein Rastkörper an der Arretierungseinheit des Tragrahmens ist zwischen der Öffnungs- und der Verriegelungsstellung verstellbar, wobei in der Verriegelungsstellung der Rastkörper mit einer entsprechenden Rastaufnahme an der Textilmaschine in Eingriff befindlich ist. In dieser Stellung bewirkt der über Rastkörper und Rastaufnahme hergestellte Formschluss eine zuverlässige Lagesicherung des Tragrahmens bzw. der Streckwerkeinheit an der Textilmaschine. Zur Freigabe der Streckwerkeinheit ist eine einfache Verlagerung des Rastkörpers aus der Rastaufnahme ausreichend, um den Tragrahmen aus der Betriebsposition in die Freigabeposition zu verstellen. Die Ausgestaltung des Rastkörpers und die entsprechende Ausgestaltung der Rastaufnahme sind dabei grundsätzlich frei wählbar. So können beispielsweise Rasthaken, die mit entsprechenden Rastbohrungen in Eingriff bringbar sind oder auch Bolzen, die von dem Rasthaken umgriffen werden, verwendet werden. Der Rastkörper kann auch als verschiebbarer Rastbolzen ausgebildet sein, welcher in der Verriegelungsstellung in eine entsprechende Rastbolzenaufnahme eingreift.Such a design of the locking unit has a particularly simple and therefore cost-effective and error-prone structure. A locking body on the locking unit of the support frame is adjustable between the opening and the locking position, with the locking body in the locking position being in engagement with a corresponding locking receptacle on the textile machine. In this position, the positive connection created via the locking body and locking receptacle ensures that the position of the support frame or the drafting unit on the textile machine is reliably secured. To release the drafting unit, a simple displacement of the locking body from the locking receptacle is sufficient to move the support frame from the operating position to the release position. The design of the locking body and the corresponding design of the locking receptacle are fundamentally freely selectable. For example, locking hooks that can be brought into engagement with corresponding locking holes or bolts that are gripped by the locking hook can be used. The locking body can also be designed as a displaceable locking bolt, which engages in a corresponding locking bolt receptacle in the locking position.
Nach einer weiteren bevorzugten Ausgestaltung der Erfindung ist ferner vorgesehen, dass der Rastkörper in Richtung auf die Verriegelungsstellung vorgespannt ist. Eine entsprechende Ausgestaltung der Erfindung gewährleistet, dass die Streckwerkeinheit nach einer Verlagerung aus der Freigabe- in die Betriebsposition selbsttätig durch den auf die Verriegelungsstellung vorgespannten Rastkörper in der Betriebsposition arretiert wird. Fehlbedienungen oder eine ausbleibende Arretierung aufgrund eines Bedienfehlers werden somit zuverlässig vermieden. Im Falle einer notwendigen Entfernung des Tragrahmens ist es lediglich erforderlich, den Rastkörper entgegen der Vorspannung in die Öffnungsstellung zu verlagern, sodass dann eine einfache Verstellung des Tragrahmens aus der Betriebs- in die Freigabeposition und dessen anschließende Entnahme von der Textilmaschine erfolgen kann.According to a further preferred embodiment of the invention it is further provided that the locking body is biased towards the locking position. A corresponding embodiment of the invention ensures that the drafting unit is automatically locked in the operating position by the locking body prestressed to the locking position after a shift from the release to the operating position. Incorrect operation or a failure to lock due to an operating error are thus reliably avoided. If the support frame needs to be removed, it is only necessary to move the locking body into the open position against the preload, so that the support frame can then be easily adjusted from the operating to the release position and then removed from the textile machine.
Der Tragrahmen weist mindestens eine Lagerstelle zum schwenkbaren Lagern eines der Streckwerkeinheit zugeordneten Belastungsträgers auf, welcher wenigstens eine Oberwalze drehbeweglich halten kann. Gemäß einer bevorzugten Weiterbildung der Erfindung ist zudem vorgesehen, dass der Tragrahmen zur Aufnahme wenigstens eines Zusatzaggregates, insbesondere zur Anordnung einer Antriebseinheit einer gemäß einer vorteilhaften Weiterbildung der Erfindung an dem Tragrahmen angeordneten Unterwalze, einer Kommunikationseinheit und/oder eines Steuergeräts der Antriebseinheit, ausgebildet ist.The support frame has at least one bearing point for pivotally supporting a load carrier assigned to the drafting unit, which can hold at least one top roller in a rotatable manner. According to a preferred development of the invention, it is also provided that the support frame is designed to accommodate at least one additional unit, in particular for arranging a drive unit of a lower roller arranged on the support frame according to an advantageous development of the invention, a communication unit and / or a control device of the drive unit.
Die Möglichkeit, an dem Tragrahmen weitere Baugruppen eines Streckwerks anzuordnen, ermöglicht es, die Streckwerkeinheit zu einem vollständigen Streckwerk auszubilden, welches in seiner Gesamtheit modular über den Tragrahmen in flexibler Weise an der Textilmaschine bzw. der zugeordneten Arbeitsstelle angeordnet bzw. von dieser entfernt werden kann. Darüber hinaus bietet eine weiter bevorzugte Ausgestaltung des Tragrahmens mit einer Befestigungsschiene zur Aufnahme des wenigstens einen Zusatzaggregates die Möglichkeit, das wenigstens eine Zusatzaggregat in einfacher Weise, bspw. über eine standardisierte Ausgestaltung der Befestigungsschiene, an dem Tragrahmen anzuordnen, zu verstellen und auch wieder von diesem zu entfernen. Eine sich hieraus ergebende höhere Flexibilität ermöglicht eine kostengünstige Wartung sowie im Bedarfsfall einen einfachen Austausch einzelner Zusatzaggregate, bei denen es sich auch um die den Oberwalzen zugeordneten Unterwalzen handeln kann.The possibility of arranging further assemblies of a drafting system on the support frame makes it possible to form the drafting system unit into a complete drafting system, which in its entirety can be arranged in a modular manner via the support frame in a flexible manner on the textile machine or the assigned workstation or can be removed from it . In addition, a further preferred embodiment of the support frame with a fastening rail for receiving the at least one additional unit offers the possibility of arranging and adjusting the at least one additional unit on the support frame in a simple manner, for example via a standardized design of the fastening rail, and also from it again to remove. The resulting greater flexibility enables cost-effective maintenance and, if necessary, easy replacement of individual additional units, which can also be the lower rollers assigned to the upper rollers.
Eine Verbindung der Streckwerkeinheit, insbesondere von einer oder mehreren an dem Tragrahmen angeordneten elektronischen Einheiten, mit einer zugeordneten Steuereinheit kann dabei in einfacher Weise über eine Kabelverbindung oder alternativ durch eine Kommunikationseinheit, die zur drahtlosen Datenübermittlung ausgebildet ist, hergestellt werden. Eine Datenübermittlung kann dabei mit einer Steuereinrichtung der Arbeitsstelle, einer Zentralsteuereinrichtung der gesamten Textilmaschine oder einer übergeordneten, mehrere Textilmaschinen steuernden Steuereinrichtung erfolgen.A connection of the drafting unit, in particular one or more electronic units arranged on the support frame, to an associated control unit can be established in a simple manner via a cable connection or alternatively via a communication unit which is designed for wireless data transmission. Data transmission can take place with a control device of the workstation, a central control device of the entire textile machine or a higher-level control device that controls several textile machines.
Nach einer weiteren Ausgestaltung der Erfindung ist vorgesehen, dass an dem Tragrahmen zwei Lagerstellen jeweils zum schwenkbaren Lagern eines Belastungsträgers vorgesehen sind, wobei die Belastungsträger insbesondere zur Lagerung mindestens einer Oberwalze zwischen den Belastungsträgern ausgebildet sind. Gegenüber den aus dem Stand der Technik bekannten Belastungsträgern, bei denen benachbart angeordnete Oberwalzen über einen durch den Belastungsträger belasteten Steg miteinander verbunden sind, ermöglicht die Anordnung der Oberwalze zwischen den Belastungsträgern eine besonders gleichmäßige Übertragung des Drucks der Oberwalze auf die zugeordnete Unterwalze, da die Belastungskraft beidseitig auf die Oberwalze wirkt und nicht mittig auf den zwischen zwei Oberwalzen verlaufenden Steg. Eine gleichmäßigere Druckverteilung gewährleistet in besonders vorteilhafter Weise während des Verzugs ein gleichmäßiges Verschieben der Fasern gegeneinander, sodass ein besonders gleichmäßiges Faserband erzeugt werden kann.According to a further embodiment of the invention, it is provided that two bearing points are provided on the support frame, each for pivotally supporting a load carrier, the load carriers being designed in particular to support at least one top roller between the load carriers. Compared to those known from the prior art Load carriers in which adjacent upper rollers are connected to one another via a web loaded by the load carrier, the arrangement of the upper roller between the load carriers enables a particularly uniform transfer of the pressure of the upper roller to the assigned lower roller, since the loading force acts on the upper roller on both sides and not in the middle on the web running between two top rollers. A more uniform pressure distribution ensures in a particularly advantageous manner that the fibers are moved evenly against one another during the draft, so that a particularly uniform sliver can be produced.
Nach einer weiteren bevorzugten Ausgestaltung der Erfindung ist vorgesehen, dass der Tragrahmen ein Handhabungselement, insbesondere ein Griffelement aufweist. Die Verwendung eines Handhabungselements, welches beispielsweise auch zur Aufnahme von geeigneten Handhabungswerkzeugen ausgebildet sein kann, ermöglicht es, den Tragrahmen in einfacher Weise von der Textilmaschine bzw. der Arbeitsstelle zu entfernen, bzw. an dieser anzuordnen. In einer besonders einfachen Ausgestaltung ist das Handhabungselement als Griffelement ausgebildet, welches es dem Bediener ermöglicht, den Tragrahmen in besonders zuverlässiger Weise zu ergreifen und auch zwischen der Betriebs- und der Freigabeposition zu verstellen. Die Anordnung eines oder mehrerer Griffelemente kann dabei unter Berücksichtigung der auftretenden Betätigungskräfte erfolgen, um eine erleichterte Bedienung zu ermöglichen.According to a further preferred embodiment of the invention it is provided that the support frame has a handling element, in particular a handle element. The use of a handling element, which can, for example, also be designed to accommodate suitable handling tools, makes it possible to easily remove the support frame from the textile machine or the workstation or to arrange it there. In a particularly simple embodiment, the handling element is designed as a grip element, which enables the operator to grip the support frame in a particularly reliable manner and also to adjust it between the operating and release positions. The arrangement of one or more handle elements can take into account the operating forces that occur in order to enable easier operation.
Kennzeichnend für das Streckwerk mit der Streckwerkeinheit, die einen mindestens eine Oberwalze aufweisenden Belastungsträger aufweist, ist, dass die Streckwerkeinheit einen Tragrahmen gemäß einer der vorstehend beschriebenen Ausführungsformen aufweist, an welchem der Belastungsträger schwenkbar gelagert ist.What is characteristic of the drafting system with the drafting system unit, which has a load carrier having at least one top roller, is that the drafting system unit has a support frame according to one of the embodiments described above, on which the load carrier is pivotally mounted.
Ein entsprechend ausgebildetes Streckwerk zeichnet sich dabei dadurch aus, dass in Abhängigkeit von den an dem Tragrahmen angeordneten Baugruppen der Streckwerkeinheit diese in einfacher und komfortabler Weise an der Textilmaschine angeordnet und auch wieder von dieser entfernt werden können. Dies ermöglicht es, Wartungs- und Instandsetzungsarbeiten sowie Einstell- und Anpassungsarbeiten in komfortabler Weise an einem separaten, von der Textilmaschine entfernten Arbeitsplatz vorzunehmen, an dem eine gute Zugänglichkeit zu sämtlichen Baugruppen der Streckwerkeinheit besteht. Die Streckwerkeinheit lässt sich vor allem in besonders zeitsparender Weise ein- und wieder ausbauen, wodurch auch Reinigungsarbeiten schneller ausgeführt und somit Stillstandzeiten der Textilmaschine reduziert werden können.A correspondingly designed drafting system is characterized in that, depending on the assemblies of the drafting system unit arranged on the support frame, they can be arranged on the textile machine in a simple and comfortable manner and can also be removed from it again. This makes it possible to carry out maintenance and repair work as well as adjustment and adjustment work in a comfortable manner at a separate workstation, away from the textile machine, where there is good access to all assemblies of the drafting unit. Above all, the drafting unit can be installed and removed again in a particularly time-saving manner, which means that cleaning work can be carried out more quickly and therefore downtimes of the textile machine can be reduced.
Auch der Austausch des Streckwerks ist in einfacher Weise möglich, sodass auf andernfalls hierfür erforderliches, entsprechend geschultes Personal verzichtet werden kann.The drafting system can also be replaced in a simple manner, meaning that the appropriately trained personnel that would otherwise be required for this can be dispensed with.
Nach einer bevorzugten Ausführungsform sind an dem Tragrahmen zwei Belastungsträger mit wenigstens einer zwischenliegenden Oberwalze gemäß einer exemplarisch vorstehend beschriebenen Ausführungsform angeordnet, wobei die beiden Belastungsträger über ein Griffelement miteinander verbindbar oder verbunden sind. Das Griffelement kann sich dabei insbesondere parallel zur Oberwalze von einem Belastungsträger zu dem anderen Belastungsträger erstrecken bzw. in einer solchen Weise an den Belastungsträgern angeordnet und lösbar befestigt werden. Ein solch gemeinsames Griffelement ermöglicht in Bauteil reduzierter und einfacher Weise eine Entnahme der Streckwerkeinheit oder des Streckwerks von der Textilmaschine bzw. der Arbeitsstelle und eine Anordnung derselbigen an der Arbeitsstelle bzw. der Textilmaschine. Die lösbare Anordnung und Befestigung des Griffelementes ermöglicht eine weitere Bauteilreduzierung. So kann ein Griffelement vom Bediener mitgeführt und im Falle von Maßnahmen an dem Streckwerk angeordnet und befestigt werden. Eine solche Befestigung kann in üblicher Weise form- oder kraftschlüssig erfolgen. Ferner ermöglicht das gemeinsame Griffelement, dass die Belastungsträger in der Betriebsposition des Tragrahmens in üblicher Weise gemeinsam in eine von den Unterwalzen beabstandete Position zur Vornahme von Maßnahmen wie Reinigen einer oder mehrerer der Ober- und/oder Unterwalzen oder sonstiger Maßnahmen, welche keine Entnahme der Streckwerkeinheit bzw. des Streckwerks von der Textilmaschine bzw. der Arbeitsstelle erfordern, verschwenkt werden können, wodurch die Handhabbarkeit weiter vereinfacht werden kann.According to a preferred embodiment, two load carriers with at least one intermediate top roller are arranged on the support frame according to an exemplary embodiment described above, the two load carriers being connectable or connected to one another via a handle element. The grip element can extend in particular parallel to the top roller from one load carrier to the other load carrier or can be arranged and releasably fastened to the load carriers in such a way. Such a common handle element makes it possible to remove the drafting unit or the drafting system from the textile machine or the workstation in a reduced and simple manner and to arrange the same at the workstation or the textile machine. The detachable arrangement and fastening of the handle element enables a further reduction in components. In this way, a handle element can be carried by the operator and, in the event of measures being taken, can be arranged and attached to the drafting system. Such an attachment can be done in the usual way in a positive or non-positive manner. Furthermore, the common handle element enables the load carriers in the operating position of the support frame to move together in the usual way into a position spaced apart from the lower rollers in order to carry out measures such as cleaning one or more of the upper and / or lower rollers or other measures that do not require removal of the drafting unit or the drafting system from the textile machine or the workstation, can be pivoted, which can further simplify handling.
Nach einer weiterhin bevorzugten Ausführungsform ist das Streckwerk als ein an der Arbeitsstelle anordbares und entnehmbares Streckwerkmodul ausgebildet. Dazu sind an dem Tragrahmen in einer wie vorstehend beispielhaft beschriebener Weise zumindest der wenigstens eine Belastungsträger mit der wenigstens einen Oberwalze, eine der wenigstens einen Oberwalze zugeordnete Unterwalze und ein die Unterwalze rotierend antreibender Antrieb angeordnet, welcher kabelgebunden oder kabellos mit einer Steuereinrichtung verbindbar ist. Weiterhin bevorzugt kann an dem Tragrahmen die Steuereinrichtung für den Antrieb der Unterwalze angeordnet und insbesondere mit dem Antrieb verbunden sein.According to a further preferred embodiment, the drafting system is designed as a drafting system module that can be arranged and removed at the work site. For this purpose, at least the at least one load carrier with the at least one upper roller, a lower roller assigned to the at least one upper roller and a drive which rotates the lower roller and which can be connected to a control device in a wired or wireless manner are arranged on the support frame in a manner as described above as an example. Furthermore, the control device for driving the lower roller can preferably be arranged on the support frame and in particular connected to the drive.
