Description

Die Erfindung betrifft eine Karde mit einem Wanderdeckel, umfassend zumindest zwei Zugmittel, die ausgebildet sind, eine Vielzahl von Deckelstäben im Bereich ihrer Stirnseiten aufzunehmen und zumindest entlang eines Teilumfanges einer Trommel der Karde zu führen, wobei die Zugmittel mit den Deckelstäben um jeweils zwei Umlenkrollen geführt werden, die oberhalb der Seitenschilder der Karde angeordnet sind, nach dem Oberbegriff von Anspruch 1.The invention relates to a card with a revolving flat, comprising at least two traction means, which are designed to accommodate a large number of flat bars in the area of their end faces and to guide them at least along part of the circumference of a drum of the card, the traction means with the flat bars being guided around two deflection rollers in each case arranged above the side shields of the card, according to the preamble of claim 1.

In der DE 2604465 A1 wird ein Wanderdeckel einer Karde offenbart, bei dem die Deckelstäbe an umlaufenden Riemen oder Ketten angeordnet und in einem Kreislauf an einem Teilumfang der Trommel vorbeigeführt werden. Hierzu sind zwei Führungsrollen an den Umlenkpunkten des Riementriebes angeordnet. Zwischen den Führungsrollen sind Führungselemente bzw. Gleitführungen angeordnet, die an Flanschen oder Baugliedern befestigt sind. Die Flansche oder Bauglieder erstrecken sich wiederum vom Seitenschild bis zur oberen Gleitführung, wodurch der Bauraum zwischen den umlaufenden Deckelstäben nur begrenzt frei zugänglich ist. Die Einstellbarkeit des Riemens bzw. der Kette erfolgt mittels einer Federwaage, indem die Auflagekraft eines Deckelstabes auf dem Flexibelbogen oder der Gleitführung gemessen wird. Das ist sehr ungenau und lässt nur indirekt auf die Spannung des Riemens oder der Kette schließen.In the DE 2604465 A1 a revolving flat of a card is disclosed, in which the flat bars are arranged on circulating belts or chains and are guided past a partial circumference of the drum in a circuit. For this purpose, two guide rollers are arranged at the deflection points of the belt drive. Guide elements or sliding guides are arranged between the guide rollers and are fastened to flanges or structural members. The flanges or structural elements in turn extend from the side plate to the upper sliding guide, as a result of which the space between the rotating flat bars is only freely accessible to a limited extent. The belt or chain can be adjusted using a spring scale by measuring the contact force of a flat bar on the flexible bend or the sliding guide. This is very imprecise and only indirectly indicates the tension of the belt or chain.

Die US 857,713 offenbart eine Karde, bei der der Bügel zur Umlenkung der Zugelemente, an denen die Deckelstäbe befestigt sind, am Gestell der Karde befestigt ist. Dadurch ergibt sich eine Führung für die Zugelemente, bei der eine Entnahme oder Inspektion der Deckelstäbe nur schwer möglich ist.The U.S. 857,713 discloses a card in which the bracket for deflecting the tension elements to which the flat bars are attached is attached to the frame of the card. This results in a guide for the tension elements in which it is difficult to remove or inspect the flat bars.

Die CN 204417686 U offenbart die Befestigung der Bügel zur Umlenkung der Zugelemente am Seitenschild. Eine Einstellung der Zugelemente ist damit sehr aufwändig.The CN 204417686 U discloses the attachment of the brackets for deflecting the tension elements on the side plate. An adjustment of the tension elements is therefore very complex.

Aufgabe der Erfindung ist die Weiterbildung eines Wanderdeckels für eine Karde, die eine leichte Zugänglichkeit der Deckelstäbe ermöglicht und die eine reproduzierbare Einstellbarkeit ermöglicht.The object of the invention is the further development of a revolving flat for a card, which enables easy access to the flat bars and which enables reproducible adjustability.

Diese Aufgabe wird mit den Merkmalen von Anspruch 1 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen angegeben.This object is solved with the features of claim 1. Advantageous developments of the invention are specified in the dependent claims.

Der erfindungsgemäße Karde weist einen Wanderdeckel auf, der zumindest zwei Zugmittel umfasst, die ausgebildet sind, eine Vielzahl von Deckelstäben im Bereich ihrer Stirnseiten aufzunehmen und zumindest entlang eines Teilumfanges einer Trommel der Karde zu führen, wobei die Zugmittel mit den Deckelstäben um jeweils zwei Umlenkrollen geführt werden, die oberhalb der Seitenschilder der Karde angeordnet sind, wobei zwischen jeweils zwei Umlenkrollen ein Bügel angeordnet ist, der ausgebildet ist, weitere Führungselemente zur Führung des Zugmittels aufzunehmen.The card according to the invention has a revolving flat, which comprises at least two traction means, which are designed to receive a large number of flat bars in the area of their end faces and to guide them at least along a partial circumference of a drum of the card, the traction means with the flat bars being guided around two deflection rollers in each case which are arranged above the side plates of the card, with a bracket being arranged between two deflection rollers in each case, which is designed to accommodate further guide elements for guiding the traction means.

Die Erfindung ist dadurch gekennzeichnet, dass die Enden des Bügels an Flanschen angeordnet sind, an denen die Umlenkrollen gelagert sind.The invention is characterized in that the ends of the bracket are arranged on flanges on which the deflection rollers are mounted.

Die Zugmittel können als Riemen oder Kette ausgebildet sein und nehmen die Deckelstäbe im Bereich ihrer Stirnseiten mit Stiften, Kunststoffelementen oder anderen Verbindungsmitteln auf. Die Zugmittel führen die Deckelstäbe entlang ihrer Deckelreise zumindest entlang eines Teilumfanges einer Trommel, so dass Fasern zwischen den Garnituren der Deckel und der Garnitur der Trommel in einem sehr geringen Spalt ausgerichtet und gereinigt werden. Die Zugmittel werden dabei um jeweils zwei Umlenkrollen geführt, wobei im Bereich einer Umlenkrolle die Deckelstäbe aus dem Kontakt mit den Fasern bzw. der Trommel herausgeführt werden und mittels Absaugung und Bürste gereinigt werden, bevor sie im Bereich der zweiten Umlenkrolle wieder an die Trommel geführt werden. Zumindest eine Rolle ist ausgebildet, mit einem Antrieb das Zugmittel anzutreiben. Dadurch, dass zwischen jeweils zwei Umlenkrollen ein Bügel angeordnet ist, der ausgebildet ist, weitere Führungselemente zur Führung des Zugmittels aufzunehmen, entsteht zwischen dem Unter- und Obertrum der Zugmittel ein Freiraum, der zur Inspektion oder Entnahme der Deckelstäbe oder deren Reinigung verwendet werden kann. Der Freiraum ist im Bereich der Seitenschilder nicht mit Befestigungselementen verbaut, an denen der Bügel angeordnet ist.The traction means can be in the form of a belt or chain and take up the flat bars in the area of their end faces with pins, plastic elements or other connecting means. The traction means guide the flat rods along their flat travel at least along part of the circumference of a drum, so that fibers between the clothings of the flats and the clothing of the drum are aligned and cleaned in a very small gap. The traction means are each guided around two deflection rollers, with the flat bars being guided out of contact with the fibers or the drum in the area of one deflection roller and being cleaned by means of suction and a brush before they are guided back to the drum in the area of the second deflection roller . At least one roller is designed to drive the traction means with a drive. Because a bracket is arranged between two deflection rollers in each case and is designed to accommodate further guide elements for guiding the traction means between the upper and lower run of the traction mechanism, a free space that can be used to inspect or remove the flat bars or to clean them. The free space in the area of the side shields is not obstructed with fastening elements on which the bracket is arranged.

Vorzugsweise weist der Bügel ein erstes und ein zweites Ende auf, die im Bereich der Umlenkrollen angeordnet sind, wobei der Bügel zumindest einen Teilabstand zwischen den Umlenkrollen bogenförmig überbrückt. Die Ausbildung des Bügels als bogenförmige Brücke ermöglicht eine hohe Stabilität und eine großzügige Gestaltungsfreiheit für den Freiraum zwischen dem Ober- und dem Untertrum der Zugmittel.The bracket preferably has a first and a second end, which are arranged in the area of the deflection rollers, the bracket bridging at least a partial distance between the deflection rollers in an arc shape. The design of the bracket as an arched bridge enables a high level of stability and a generous design freedom for the free space between the upper and lower runs of the traction means.

In einer vorteilhaften Ausführungsform ist ein erstes Ende des Bügels drehbar ausgebildet und das zweite Ende weist eine Auflage auf, das auf einem Einstellelement aufliegt. Es ergibt sich eine leichte Montage des Bügels, der nicht mehr aufwändig am Seitenschild der Karde montiert und justiert werden muss.In an advantageous embodiment, a first end of the bracket is rotatable and the second end has a support that rests on an adjustment element. The bracket is easy to assemble, which no longer has to be laboriously assembled and adjusted on the side plate of the card.

Dadurch, dass das zweite Ende des Bügels durch die Spannung des Zugmittels auf das Einstellelement gedrückt wird, kann auf eine aktive Befestigung des Bügels an diesem zweiten Ende verzichtet werden. Die Spannung des Zugmittels sorgt für eine dauerhafte und genaue Auflage auf das Einstellelement.Due to the fact that the second end of the bracket is pressed onto the adjustment element by the tension of the traction means, there is no need for an active attachment of the bracket to this second end. The tension of the traction device ensures a permanent and precise support on the adjustment element.

Vorzugsweise ist das Einstellelement als Exzenter ausgebildet, das mit der Auflage des Bügels zusammenwirkt. Über den Exzenter kann die Spannkraft auf das Zugmittel eingestellt werden, denn je nach Stellung des Exzenters drückt der Bügel mehr oder weniger gegen die Spannung des Zugmittels.The adjustment element is preferably designed as an eccentric which interacts with the support of the bracket. The clamping force on the traction device can be adjusted via the eccentric, because depending on the position of the eccentric, the bracket presses more or less against the tension of the traction device.

Dadurch, dass der Bügel ausgebildet ist, mit seinem ersten Ende mit einer definierten Kraft um einen Drehpunkt verschwenkt zu werden, kann die Spannung auf das Zugmittel leicht und genau eingestellt werdenDue to the fact that the bracket is designed so that its first end can be pivoted about a pivot point with a defined force, the tension on the traction means can be adjusted easily and precisely

Vorzugsweise wird eine definierte Kraft am zweiten Ende des Bügels eingeleitet, wobei die verschwenkte Position des Bügels durch ein Verspannen des Exzenters, der sich mit der Auflage des Bügels in Kontakt befindet, fixiert wird. Die definierte Kraft kann beispielsweise mit Federn, pneumatischen oder hydraulischen Mitteln oder mittels Hebelkraft erzeugt werden.A defined force is preferably introduced at the second end of the bracket, the pivoted position of the bracket being fixed by bracing the eccentric, which is in contact with the support of the bracket. The defined force can be generated, for example, with springs, pneumatic or hydraulic means, or by means of leverage.

Dadurch, dass die definierte Kraft mit einem Hebel und einem Gewicht erzeugt wird, die zur Einstellung der Spannung des Zugmittels im Bereich des zweiten Endes des Bügels an der Karde montierbar sind, ergibt sich eine einfache und reproduzierbare Einstellbarkeit der Spannung auf die Zugmittel. Der Hebel und das Gewicht können innerhalb der Karde einfach deponiert werden oder den Monteuren mitgegeben werden.The fact that the defined force is generated with a lever and a weight that can be mounted on the card to adjust the tension of the traction means in the area of the second end of the bracket results in a simple and reproducible adjustability of the tension on the traction means. The lever and the weight can simply be deposited inside the card or given to the fitters.

Vorzugsweise weist der Bügel zumindest zwei weitere Umlenkrollen zur Führung des Zugmittels auf, wodurch eine geringe Reibung auf die Umlenkung des Zugmittels wirkt. Die Verwendung von zwei weiteren Umlenkrollen, also insgesamt vier Umlenkrollen pro Bügel ermöglicht die Verwendung von Umlenkrollen mit geringem Durchmesser, wodurch der Freiraum zwischen dem Ober- und Untertrum des Zugmittels vergrößert werden kann.The bracket preferably has at least two further deflection rollers for guiding the traction means, as a result of which little friction acts on the deflection of the traction means. The use of two additional deflection rollers, i.e. a total of four deflection rollers per bracket, enables the use of deflection rollers with a small diameter, as a result of which the free space between the upper and lower runs of the traction means can be increased.

Das weitere Führungselement am Bügel reduziert die Spannung am Zugmittel aufgrund des Gewichtes der Deckelstäbe.The additional guide element on the bracket reduces the tension on the traction mechanism due to the weight of the flat bars.

Mit dem erfindungsgemäßen Wanderdeckel lässt sich ein großer Freiraum zwischen dem Zugmittel schaffen, mit dem leicht die Deckelstäbe montiert oder entnommen werden können. Der Freiraum ist außerdem geeignet, den Zustand der Deckelstäbe zu begutachten und kann zur Reinigung des Wanderdeckels genutzt werden. Gleichzeitig lässt sich das Zugmittel mit einfachsten Mitteln reproduzierbar spannen.With the revolving flat according to the invention, a large free space can be created between the traction means, with which the flat bars can be easily mounted or can be removed. The free space is also suitable for examining the condition of the flat bars and can be used to clean the revolving flat. At the same time, the traction mechanism can be tightened reproducibly with the simplest of means.

Der entstehende Faserflor wird nachfolgend über einen Abnehmer 5, eine Abnehmerwalze 6 und mehreren Quetschwalzen 7, 8, zu einem Vliesleitelement 9 gefördert, der den Faserflor mit einem Trichter 10 zu einem Faserband umformt, das über Abzugswalzen 11, 12 an eine nachfolgende Verarbeitungsmaschine oder eine Kanne 15 übergibt. 1 shows a card 100 according to the prior art, in which fiber tufts are guided via a chute to a feed roller 1, a feed table 2, via a plurality of lickerins 3a, 3b, 3c, to the drum 4 or the spool. On the drum 4, the fibers of the fiber tufts are parallelized and cleaned by means of stationary carding elements 20 arranged on a revolving flat 17. The resulting fibrous web is then conveyed via a doffer 5, a doffer roller 6 and several squeezing rollers 7, 8 to a fleece guide element 9, which uses a funnel 10 to shape the fibrous web into a sliver, which is conveyed via take-off rollers 11, 12 to a downstream processing machine or a Pot 15 passes.

Figur 2 zeigt einen Wanderdeckel 17 nach dem Stand der Technik. Der Wanderdeckel 17 umfasst zumindest zwei Riemen 17a, die beidseitig der Trommel 4 angeordnet sind und im Bereich der Stirnseiten der Deckelstäbe 20 mit daran angeordneten Stiften zusammenwirken. Das heißt, jeder Deckelstab 20 ist beidseitig mittels der stirnseitig angeordneten Stifte in jeweils einem Riemen 17a befestigt, die oberhalb der Seitenschilder 22 geführt und umlaufend angeordnet sind. In den nachfolgenden Darstellungen wird nur eine Seite der Karde dargestellt, wobei dem Fachmann klar ist, dass der hier beschriebene Wanderdeckel 17 beidseitig der Karde geführt ist. Jeder Riemen 17a wird über mindestens zwei Umlenkrollen 24, 25 geführt, wobei die Umlenkrollen 24 und 25 an Lagerelementen 24a, 25a drehbar angeordnet sind. Die Lagerelemente 24a, 25a wiederum sind an den Seitenschildern 22 der Karde 100 angeordnet. Zumindest einer der Umlenkrollen 24 oder 25 ist mit einem Antrieb gekoppelt, über den die Riemen 17a mit den Wanderdeckeln 20 entlang ihrer Deckelreise angetrieben werden. Zwischen den Umlenkrollen 24, 25 können weitere Umlenkrollen 26, 27 oder Führungen für den Riemen 17a angeordnet sein. Beidseitig der Trommel 4 ist am Seitenschild 22 jeweils ein Bügel 23 angeordnet, an dem die beiden mittleren Umlenkrollen 26, 27 angeordnet und drehbar gelagert sind. Jeder Bügel 23 ist ebenfalls am Seitenschild 22 der Karde 100 angeordnet und ausgebildet, mittels einer Einstellvorrichtung 23a die Spannung der Riemen 17a einzustellen. figure 2 shows a revolving flat 17 according to the prior art. The revolving flat 17 comprises at least two belts 17a, which are arranged on both sides of the drum 4 and interact in the area of the end faces of the flat bars 20 with pins arranged thereon. This means that each flat bar 20 is fastened on both sides by means of the pins arranged on the front side in a respective belt 17a, which is guided above the side plates 22 and arranged circumferentially. Only one side of the card is shown in the following illustrations, it being clear to the person skilled in the art that the revolving flat 17 described here is guided on both sides of the card. Each belt 17a is guided over at least two deflection rollers 24, 25, the deflection rollers 24 and 25 being rotatably arranged on bearing elements 24a, 25a. The bearing elements 24a, 25a in turn are arranged on the side plates 22 of the card 100. At least one of the deflection rollers 24 or 25 is coupled to a drive, via which the belts 17a with the revolving flats 20 are driven along their flat journey. Further deflection rollers 26, 27 or guides for the belt 17a can be arranged between the deflection rollers 24, 25. A bracket 23 is arranged on each side of the drum 4 on the side plate 22, on which the two central deflection rollers 26, 27 are arranged and rotatably mounted. Each bracket 23 is also arranged on the side plate 22 of the card 100 and is designed to adjust the tension of the belts 17a by means of an adjustment device 23a.

An einem Lagerelement 25a ist ebenfalls eine Absaugung 30 angeordnet, mit der Schmutz und Faserreste aus den Garnituren der Deckelstäbe abgesaugt werden. Neben der Absaugung 30 ist am Bügel 23 eine nicht weiter bezeichnete Reinigungsvorrichtung in Form einer rotierenden Bürste angeordnet. Die Deckelstäbe 20 laufen zwischen den Umlenkrollen 24 und 25 an der Trommel 4 über eine Gleitleiste 18, die an einem Flexibelbogen 21 angeordnet ist. Der Flexibelbogen 21 ist mittels Stellspindel 19 einstellbar am Seitenschild angeordnet. Die Gleitleiste 18 kann im Abstand zum Flexibelbogen 21 konzentrisch zur Trommel einstellbar ausgebildet sein. Über die Einstellung des Flexibelbogens 21 und der Gleitleiste 18 lässt sich der Kardierspalt zwischen der Trommel 4 und den Deckelstäben 20 einstellen. In dem Ausführungsbeispiel der Figur 2 bewegen sich die Deckelstäbe 20 im Bereich der Trommel 4 bzw. des sichtbaren Seitenschildes 22 gegen die Drehrichtung der Trommel 4 nach links, wobei die Deckelstäbe 20 hier über der Gleitleiste 18 geführt werden. Nach der Umlenkung um die Umlenkrolle 25 werden die Deckelstäbe 20 durch den Riemen 17a in dieser Darstellung nach rechts bewegt. Die Spannung des Riemens 17a wird ausschließlich durch den Bügel 23 erzeugt, der an einer mittigen Position am Seitenschild 22 einstellbar angeordnet ist. Die Kontur des Bügels 23 entspricht der dreieckigen Kontur eines umgedrehten Kleiderbügels, wobei an einer zentralen Ecke (der Aufhängung des Kleiderbügels) die Einstellvorrichtung 23a mit der Befestigung am Seitenschild 22 angeordnet ist, und an den beiden anderen Ecken die Umlenkrollen 26 und 27 drehbar gelagert sind. Die Anordnung und Kontur des Bügels 23 hat den Nachteil der aufwändigen Einstellbarkeit der Riemenspannung und der mangelhaften Zugänglichkeit im Wanderdeckel 17 zwischen den Deckelstäben 20.A suction device 30 is also arranged on a bearing element 25a, with which dirt and fiber residues are sucked out of the clothings of the flat bars. In addition to the suction device 30, a cleaning device, not designated further, in the form of a rotating brush is arranged on the bracket 23. The flat bars 20 run between the deflection rollers 24 and 25 on the drum 4 over a sliding strip 18 which is arranged on a flexible bend 21 . The flexible bend 21 is arranged on the side plate so that it can be adjusted by means of an adjusting spindle 19 . The sliding bar 18 can be designed to be adjustable at a distance from the flexible bend 21 concentrically to the drum. The carding gap between the drum 4 and the flat bars 20 can be adjusted by adjusting the flexible bend 21 and the slide bar 18 . In the embodiment of figure 2 move the flat bars 20 in the region of the drum 4 or the visible side plate 22 against the direction of rotation of the drum 4 to the left, with the flat bars 20 being guided over the sliding strip 18 here. After being deflected around the deflection roller 25, the flat bars 20 are moved to the right in this illustration by the belt 17a. The tension of the belt 17a is generated exclusively by the bracket 23, which is arranged adjustably at a central position on the side plate 22. The contour of the hanger 23 corresponds to the triangular contour of an inverted clothes hanger, with the adjustment device 23a with the attachment to the side plate 22 being arranged at a central corner (the hanger’s hanger), and the deflection rollers 26 and 27 being rotatably mounted at the other two corners . The arrangement and contour of the bracket 23 has the disadvantage of the complex adjustability of the belt tension and the lack of accessibility in the revolving flat 17 between the flat bars 20.

Nach Figur 3 wird der erfindungsgemäße Wanderdeckel 17 auf jeder Seite der Karde 100 zwischen den Umlenkrollen 24 und 25 an mindestens zwei weiteren Umlenkrollen 26, 27 geführt, die an einem gebogenen Bügel 23 angeordnet sind. Der Bügel 23 überspannt das obere Trum des Riemens 17a, der sich nicht im Bereich der Trommel 4 befindet. Die Befestigung des Bügels 23 erfolgt an zwei Flanschen 24b, 25b, die an den Lagerelementen 24a, 25a angeordnet sind. Dabei ist der Bügel 23 mit einem ersten Ende an einem ersten Flansch 25b um den Drehpunkt 31 drehbar angeordnet. Das zweite Ende des Bügels 23 liegt an einem zweiten Flansch 24b mit einer Auflage 23b lose auf einem Einstellelement auf, das am zweiten Flansch 24b angeordnet ist und wird durch die Spannung des Riemens 17a gegen die Auflage 23b gedrückt. Der Bügel 23 hat damit die Form einer Brücke, die den Abstand zwischen den Flanschen 24b, 25b bogenförmig überbrückt. Zwischen dem Bügel 23 und dem Seitenschild 22 oberhalb der Trommel 4 ergibt sich ein von beiden Seiten der Trommel 4 zugänglicher Freiraum, der für Reinigungsarbeiten oder auch für die Inspektion oder Entnahme von einzelnen Deckelstäben 20 genutzt werden kann. Vorteilhafterweise ist die Oberseite des Bügels 23 konvex ausgebildet, und die Unterseite des Bügels 23 konkav, um einerseits eine ausreichende Stabilität zu gewährleisten, andererseits um den Freiraum zwischen dem Bügel 23 und dem Seitenschild 22 oberhalb der Trommel 4 so groß wie möglich zu gestalten.After figure 3 the revolving flat 17 according to the invention is guided on each side of the card 100 between the deflection rollers 24 and 25 on at least two further deflection rollers 26, 27 which are arranged on a curved bracket 23. The bracket 23 spans the upper run of the belt 17a, which is not in the area of the drum 4. The bracket 23 is fastened to two flanges 24b, 25b which are arranged on the bearing elements 24a, 25a. In this case, the bracket 23 is arranged with a first end on a first flange 25b so as to be rotatable about the pivot point 31 . The second end of the bracket 23 rests against a second flange 24b with a seat 23b loose on an adjuster which is arranged on the second flange 24b and is pressed against the support 23b by the tension of the belt 17a. The bracket 23 thus has the form of a bridge which bridges the distance between the flanges 24b, 25b in the form of an arc. Between the bracket 23 and the side plate 22 above the drum 4 there is a free space that is accessible from both sides of the drum 4 and can be used for cleaning work or for the inspection or removal of individual flat bars 20 . Advantageously, the upper side of the bracket 23 is convex and the underside of the bracket 23 is concave, on the one hand to ensure sufficient stability and on the other hand to make the free space between the bracket 23 and the side plate 22 above the drum 4 as large as possible.

In einer vorteilhaften Ausgestaltung sind an jedem Bügel 23 vier Umlenkrollen 26, 27, 28, 29 angeordnet, mit denen eine ausreichende Führung für jeden Riemen 17a gewährleistet ist.In an advantageous embodiment, four deflection rollers 26, 27, 28, 29 are arranged on each bracket 23, with which adequate guidance for each belt 17a is ensured.

Das Ausführungsbeispiel der Figuren 4 und 4a zeigt die Anordnung des Bügels 23 zwischen den Flanschen 25b und 24b ohne den Riemen 17a und ohne die Deckelstäbe 20. Über den Drehpunkt 31 ist der Bügel 23 mit einem ersten Ende am Flansch 25b drehbar befestigt. Das zweite Ende des Bügels 23 liegt mit seiner Auflage 23b auf einem Einstellelement auf, das in diesem Ausführungsbeispiel als drehbarer Exzenter 32 ausgebildet ist. Am zweiten Flansch 24b ist ein Drehpunkt 24c angeordnet, an den für den Einstellvorgang des Wanderdeckels 17 ein zweiarmiger Hebel 33 befestigt werden kann. Der Hebel 33 weist an einer Seite des Drehpunktes 24c einen kurzen Hebelarm auf, der mit der zweiten Seite des Bügels 23 zusammenwirkt. Ein längerer Hebelarm des Hebels 33 ist auf der vom Drehpunkt 24c des Bügels 23 abgewandten Seite angeordnet und ausgebildet, ein Gewicht 34 aufzunehmen. Das Gewicht 34 in Verbindung mit dem zweiarmigen Hebel 33 erzeugt auf das zweite Ende des Bügels 23 eine Kraft gegen den Riemen 17a, der damit mit einer reproduzierbaren Kraft gespannt wird. Um die Spannung aufrecht zu halten, wird der Exzenter 32 auf Kontakt an die Auflage 23b des Bügels 23 gedreht und fixiert. Der Riemen 17a für den Wanderdeckel 17 ist damit auf jeder Seite der Karde 100 reproduzierbar zu spannen. Nach der Einstellung des Riemens wird der Hebel 33 mit dem Gewicht 34 wieder entfernt. Statt der Ausführung mit dem Hebel 33 und dem Gewicht 34 ist jede andere vordefinierte Kraftbelastung auf das zweite Ende des Bügels 23 geeignet, eine reproduzierbare Spannung auf den Riemen 17a zu erzeugen, beispielsweise eine Federanordnung, oder ein pneumatisches oder hydraulisches Spannelement.The embodiment of Figures 4 and 4a shows the arrangement of the bracket 23 between the flanges 25b and 24b without the belt 17a and without the flat bars 20. About the pivot point 31, the bracket 23 is rotatably attached at a first end to the flange 25b. The second end of the bracket 23 rests with its support 23b on an adjustment element which is designed as a rotatable eccentric 32 in this exemplary embodiment. A pivot point 24c is arranged on the second flange 24b, to which a two-armed lever 33 can be attached for the adjustment process of the revolving flat 17. The lever 33 has a short lever arm on one side of the pivot point 24c which interacts with the second side of the bracket 23 . A longer lever arm of the lever 33 is arranged on the side facing away from the pivot point 24c of the bracket 23 and is designed to receive a weight 34 . The weight 34 in conjunction with the two-armed lever 33 generates a force against the belt 17a on the second end of the bracket 23, which is thus connected to a reproducible force is clamped. In order to maintain the tension, the eccentric 32 is turned and fixed in contact with the support 23b of the bracket 23 . The belt 17a for the revolving flat 17 can thus be tightened on each side of the card 100 in a reproducible manner. After the belt has been adjusted, the lever 33 with the weight 34 is removed again. Instead of the embodiment with the lever 33 and the weight 34, any other predefined force loading on the second end of the bracket 23 is suitable for generating a reproducible tension on the belt 17a, for example a spring arrangement, or a pneumatic or hydraulic tensioning element.

Figur 5 zeigt die Führung eines Riemens von der Rückseite des Bügels 23 ohne den Riemen und ohne die Deckelstäbe. Erkennbar sind die Umlenkrollen 24 und 25, von denen zumindest eine mit einem Antrieb gekoppelt ist und die den Riemen im Bereich der Trommel umlenken und führen. Am Bügel 23 sind in diesem Ausführungsbeispiel vier Umlenkrollen 26, 27, 28, 29 angeordnet. Zwischen den Rollen 26, 28 und den Rollen 27, 29 ist am Bügel 23 ein weiteres Führungselement 35 für den Riemen 17a angeordnet. Ein weiteres Führungselement 35 ist am Flansch 24b angeordnet, das sich zwischen der Umlenkrolle 24 und der Umlenkrolle 26 am Bügel 23 erstreckt. Auch der Flansch 25b weist ein Führungselement 35 auf, das sich von der Umlenkrolle 25 zur Umlenkrolle 27 erstreckt. figure 5 Figure 12 shows the routing of a strap from the rear of the bracket 23 without the strap and without the flat bars. The deflection rollers 24 and 25 can be seen, of which at least one is coupled to a drive and which deflect and guide the belt in the region of the drum. In this exemplary embodiment, four deflection rollers 26, 27, 28, 29 are arranged on the bracket 23. A further guide element 35 for the belt 17a is arranged on the bracket 23 between the rollers 26, 28 and the rollers 27, 29. Another guide element 35 is arranged on the flange 24b, which extends between the deflection roller 24 and the deflection roller 26 on the bracket 23. The flange 25b also has a guide element 35 which extends from the deflection roller 25 to the deflection roller 27 .

Mittels der Führungselemente 35, die in diesem Ausführungsbeispiel als einfache Winkel ausgebildet sind, lässt sich der Riemen 17a mit den daran angeordneten Deckelstäben 20 auf einer geraden Bahn zwischen den Umlenkrollen führen, ohne dass das Gewicht der Deckelstäbe 20 hier eine zusätzliche Spannung in den Riemen 17a einfließen lässt.By means of the guide elements 35, which are designed as simple angles in this exemplary embodiment, the belt 17a with the flat bars 20 arranged on it can be guided on a straight path between the deflection rollers without the weight of the flat bars 20 causing additional tension in the belts 17a lets flow in.

Durch die erfindungsgemäße Vorrichtung wird eine leichte und reproduzierbare Einstellung der Riemenspannung beim Wanderdeckel 17 erreicht, wobei durch die Ausbildung und Anordnung des Bügels 23 ein großer Freiraum innerhalb des Wanderdeckels geschaffen wird, so dass Reinigungsarbeiten oder der Austausch und die Inspektion von Deckelstäben 20 vereinfacht wird.The device according to the invention enables easy and reproducible adjustment of the belt tension in the revolving flat 17 achieved, with the design and arrangement of the bracket 23 a large free space is created within the revolving flat, so that cleaning work or the replacement and inspection of flat bars 20 is simplified.
