Description

Die Erfindung betrifft eine Vliesleitbrücke für eine Karde oder Krempel zur Führung eines Faservlieses.The invention relates to a Vliesleitbrücke for a card or carding to guide a fiber web.

Karden und Krempel werden zum Reinigen und Öffnen von Baumwolle, Chemiefasern oder anderem Fasergut benutzt. In der Auslaufpartie, definiert durch die Anordnung von einem Abnehmer, einer Abnahmewalze und einem Quetschwalzenpaar wird ein Faservlies geformt. Es kann auch ein nachfolgendes, quer zum Faservlies angeordnetes, Förderband vorgesehen sein, durch welches das Faservlies zusammengeführt wird um ein Faserband zu bilden. In dieser Auslaufpartie werden die Fasern mehrmals von Walze zu Walze übergeben, wobei das durch den Abnehmer gebildete Faservlies von der Abnahmewalze zum Quetschwalzenpaar über eine Vliesleitbrücke geführt wird.Cards and cards are used to clean and open cotton, chemical fibers or other fiber material. In the discharge section, defined by the arrangement of a pickup, a take-off roll and a nip roll pair, a non-woven fabric is formed. It may also be a subsequent, arranged transversely to the fiber web, conveyor belt may be provided, through which the nonwoven fabric is brought together to form a sliver. In this discharge section, the fibers are transferred from roller to roller several times, wherein the nonwoven fabric formed by the purchaser is guided by the removal roller to the nip roller pair via a Vliesleitbrücke.

Abhängig von den verarbeitenden Fasern werden durch das Gleiten des Faservlieses über die Oberfläche der Vliesleitbrücke auf dieser Oberfläche Verschmutzungen abgelagert. Diese Ablagerungen führen einerseits zu einer Verschlechterung der Gleiteigenschaften der Oberfläche und andrerseits ergibt sich die Gefahr, dass sich Ablagerungen lösen und zu einer Verschmutzung des Faservlieses führen. Um die Ablagerungen zu beseitigen ist eine periodische Reinigung der Oberfläche der Vliesleitbrücke notwendig.Depending on the processing fibers, soiling is deposited on the surface by sliding the nonwoven over the surface of the nonwoven guide bridge. On the one hand, these deposits lead to a worsening of the sliding properties of the surface and, on the other hand, there is the danger that deposits will detach and lead to contamination of the fiber fleece. In order to eliminate the deposits, a periodic cleaning of the surface of the Vliesleitbrücke is necessary.

Aus dem Stand der Technik sind verschiedene Konstruktionen von Vliesleitbrücken bekannt. Beispielsweise offenbart die DE 43 28 431 eine Vliesleitbrücke welche von einer Seite her in die Arbeitsposition eingeschoben werden kann. Dies ermöglicht einen Ausbau zur Reinigung und einen nachfolgenden Einbau der Vliesleitbrücke ohne eine erneute Einstellung vornehmen zu müssen. Nachteilig an der vorgeschlagenen Lösung ist, dass der Aus- und Einbau und somit auch die Erneuerung der Vliesleitbrücke aufwändig ist.Various constructions of nonwoven guide bridges are known from the prior art. For example, the DE 43 28 431 a Vliesleitbrücke which can be inserted from one side into the working position. This allows for removal for cleaning and subsequent installation of Vliesleitbrücke without having to make a new setting. A disadvantage of the proposed solution is that the removal and installation and thus the renewal of Vliesleitbrücke is complex.

Der Erfindung liegt die Aufgabe zugrunde, eine Vliesleitbrücke der eingangs beschriebenen Art zu schaffen, welche eine einfache Reinigung der Oberfläche der Vliesleitbrücke und eine Anpassung der Oberfläche an das zu verarbeitende Fasergut ermöglicht.The invention has for its object to provide a Vliesleitbrücke of the type described above, which allows easy cleaning of the surface of the Vliesleitbrücke and an adaptation of the surface of the fiber to be processed.

Die Aufgabe wird gelöst durch die Merkmale im kennzeichnenden Teil der unabhängigen Ansprüche. Zur Lösung der Aufgabe wird vorgeschlagen eine Vliesleitbrücke für eine Karde oder Krempel zur Führung eines Faservlieses vorzusehen, wobei die Vliesleitbrücke eine Längsachse aufweist und die Vliesleitbrücke zumindest auf einer dem Faservlies zugewandten Seite mit einem Gleitelement versehen ist.The object is solved by the features in the characterizing part of the independent claims. To solve the problem it is proposed to provide a Vliesleitbrücke for a carding or carding machine for guiding a fiber web, wherein the Vliesleitbrücke has a longitudinal axis and the Vliesleitbrücke is provided at least on a non-woven fabric side facing with a sliding element.

Dadurch, dass die Vliesleitbrücke mit einem Gleitelement versehen wird, ist es nicht mehr notwendig zur Reinigung der Oberfläche der Vliesleitbrücke die Vliesleitbrücke auszubauen. Es genügt ein Ausbau respektive Ersatz des Gleitelementes bei starker Verschmutzung der Oberfläche des Gleitelementes. Es wird dadurch auch die Möglichkeit geschaffen, aufgrund des zu verarbeitenden Materials ein entsprechendes Gleitelement zu wählen und einzusetzen. Dabei muss nicht die gesamte Vliesleitbrücke ausgewechselt werden. Das Gleitelement ist vorteilhafterweise auf die Vliesleitbrücke in deren Längsrichtung aufgeschoben. Dabei kann das Gleitelement entsprechend an die Form der Vliesleitbrücke angepasst sein. Es ist jedoch auch möglich eine Art von Schwalbenschwanzführung in der Richtung der Längsachse der Vliesleitbrücke vorzusehen. Schwalbenschwanzführungen sind aus dem Stand der Technik in vielfältiger Ausführung bekannt. Die Fixierung des Gleitelements in einer definierten Position gegenüber der Vliesleitbrücke wird auf diese Weise durch einen Formschluss zwischen Gleitelement und der Vliesleitbrücke erreicht. Zur Sicherung des Gleitelementes auf der Vliesleitbrücke können zusätzlich Anschläge oder Sicherungselemente vorgesehen werden. Auch kann das Ende des Gleitelementes entsprechend geformt sein, sodass das Gleitelement nicht über die Vliesleitbrücke hinaus geschoben werden kann.The fact that the Vliesleitbrücke is provided with a sliding element, it is no longer necessary to remove the Vliesleitbrücke to clean the surface of Vliesleitbrücke. It is sufficient to expand or replace the sliding element with heavy contamination of the surface of the sliding element. It also creates the opportunity to choose and use a corresponding slider due to the material to be processed. It is not necessary to replace the entire Vliesleitbrücke. The sliding element is advantageously pushed onto the Vliesleitbrücke in the longitudinal direction. In this case, the sliding element can be adapted to the shape of the Vliesleitbrücke accordingly. However, it is also possible to provide a type of dovetail guide in the direction of the longitudinal axis of the Vliesleitbrücke. Dovetail guides are known from the prior art in a variety of designs. The fixation of the sliding element in a defined position relative to the Vliesleitbrücke is achieved in this way by a positive connection between the sliding element and the Vliesleitbrücke. To secure the sliding element on the Vliesleitbrücke additional stops or security elements can be provided. Also, the end of the slider can be shaped accordingly, so that the slider can not be pushed over the Vliesleitbrücke addition.

In einer weiteren Ausführungsform ist das Gleitelement auf die Vliesleitbrücke aufgeklipst. Die Montage erfolgt dabei durch eine kurzzeitige Verformung des Gleitelements sodass dieses über die Vliesleitbrücke gestülpt werden kann, wonach das Gleitelement wieder seine ursprüngliche Form annimmt. Auch in dieser Ausführung wird das Gleitelement durch einen Formschluss auf der Vliesleitbrücke gehalten.
Die Befestigung kann in einer weiteren Ausführungsform auch durch eine Schnappvorrichtung vorgesehen werden. Die Schnappvorrichtung ist dabei so anzuordnen, dass die Führung des Faservlieses durch das Gleitelement nicht beeinträchtigt wird. Schnappvorrichtungen sind in verschiedenster Ausführung aus dem Stand der Technik bekannt. Das Vorsehen einer Schnappverbindung hat den Vorteil, dass für einen Austausch des Gleitelements kein Werkzeug benötigt wird.In a further embodiment, the sliding element is clipped onto the Vliesleitbrücke. The assembly is carried out by a brief deformation of the sliding element so that it can be slipped over the Vliesleitbrücke, after which the sliding element assumes its original shape. Also in this embodiment, the slider is held by a positive connection on the Vliesleitbrücke.
The attachment can also be provided by a snap device in a further embodiment. The snap device is to be arranged so that the leadership of the nonwoven fabric is not affected by the slider. Snap devices are known in various designs from the prior art. The provision of a snap connection has the advantage that no tool is required for an exchange of the sliding element.

Erfindungsgemäß ist die Vliesleitbrücke als ein Hohlprofil ausgebildet, wodurch sich die Möglichkeit ergibt eine verwindungssteife Konstruktion bei geringem Gewicht zu realisieren.According to the Vliesleitbrücke is designed as a hollow profile, which gives the possibility to realize a torsionally rigid construction with low weight.

Bevorzugterweise ist das Gleitelement aus Metall gefertigt. Besonders bevorzugt wird dabei Chromstahl verwendet. Chromstähle sind rostfrei und weisen bei entsprechender Bearbeitung der Oberfläche gute Gleiteigenschaften auf. Zweckmässigerweise ist das Gleitelement aus einem Blech geformt.
In einer weiteren Ausführungsform ist das Gleitelement aus Kunststoff. Dadurch kann das Gleitelement selbst als Clip ausgeführt werden und es sind keine weiteren Befestigungsmittel notwendig. Die Materialwahl kann dabei auf die Bedürfnisse hinsichtlich der Gleiteigenschaften auf das zu verarbeitende Fasergut abgestimmt werden. Da das Gleitelement auf der Vliesleitbrücke aufliegt und durch diese gestützt wird ist keine verwindungs- oder biegesteife Ausführung des Gleitelements notwendig.
In einer weiteren Ausführungsform kann das Gleitelement aus einem Grundwerkstoff mit einer Beschichtung bestehen. Bevorzugterweise ist der Grundwerkstoff ein Metall und die Beschichtung aus Kunststoff. Als Kunststoff kann vorteilhafterweise ein Material mit guten Gleiteigenschaften, beispielsweise PTFE (Polytetrafluoräthylen, auch als Teflon bekannt) verwendet werden. Als Grundwerkstoff eignet sich auch Aluminium oder Stahl. Die Beschichtung kann dabei auch durch eine chemische Behandlung des Grundwerkstoffes erfolgen oder anderweitig auf den Grundwerkstoff aufgebracht werden, beispielsweise durch Kleben, Spritzen oder Streichen. Bei dieser Verfahrensweise können hochwertige Materialien als Beschichtung genutzt werden, beispielsweise in Form von Folien.Preferably, the sliding element is made of metal. Chromium steel is particularly preferably used. Chromium steels are rust-free and have good sliding properties if the surface is treated accordingly. Conveniently, the sliding element is formed from a metal sheet.
In a further embodiment, the sliding element is made of plastic. As a result, the sliding element itself can be designed as a clip and no further fastening means are necessary. The choice of material can be tailored to the needs of the sliding properties of the processed fiber material. Since the sliding element rests on the Vliesleitbrücke and is supported by this is no torsion or bending stiff design of the sliding element necessary.
In a further embodiment, the sliding element may consist of a base material with a coating. Preferably, the base material is a metal and the plastic coating. As a plastic advantageously a material with good sliding properties, such as PTFE (polytetrafluoroethylene, also known as Teflon) can be used. The basic material is also aluminum or steel. The coating can also be done by a chemical treatment of the base material or otherwise applied to the base material, for example by gluing, spraying or brushing. In this procedure, high quality materials can be used as a coating, for example in the form of films.

Bevorzugterweise findet eine derartige Vliesleitbrücke Anwendung in einer Karde, dabei hat die Karde einen Abnehmer, eine Abnahmewalze und ein Quetschwalzenpaar.
Unterhalb der Abnahmewalze ist zwischen dem Abnehmer und dem Quetschwalzenpaar eine Vliesleitbrücke mit deinem Gleitelement angeordnet. Durch die Vliesleitbrücke wird das Faservlies, welches auf dem Abnehmer gebildet und von der Abnahmewalze übernommen wird zum Quetschwalzenpaar geführt. Das Faservlies gleitet dabei auf dem Gleitelement.Preferably, such Vliesleitbrücke finds application in a card, while the card has a taker, a take-off roll and a pair of nip rollers.
Below the take-off roll a Vliesleitbrücke is arranged with your slider between the customer and the nip rollers. Through the Vliesleitbrücke the nonwoven fabric, which is formed on the customer and taken over by the take-off roll is guided to Quetschwalzenpaar. The fiber fleece slides on the sliding element.

Figur 1 zeigt in einer Seitenansicht einer an sich bekannten Karde 1 in schematischer Darstellung. Das zu kardierende Fasermaterial 2, das aus Naturfasern oder synthetischen Fasern oder Mischungen derselben bestehen kann, wird in Form von aufgelösten und gereinigten Flocken in den Füllschacht (nicht gezeigt) eingespeist, von einer Einlaufpartie 3 übernommen und einem Tambour bzw. einer Trommel 4 übergeben. Die Einlaufpartie 3 kann dabei mehrere Vorreisserwalzen aufweisen und übergibt das als Wattenvorlage übernommene Fasermaterial 2 an die Trommel 4. Das Fasermaterial 2 wird auf der Trommel 4 aufgelöst, und die einzelnen Fasern werden parallelisiert. Dieser Vorgang geschieht durch das Zusammenwirken von Trommel 4 und Wanderdeckelaggregat 6, respektive die in der Kardierzone 5 angeordneten Kardier- und Reinigungselemente. Nachdem die Fasern zum Teil mehrere Umläufe auf der Trommel 4 durchgeführt haben, werden sie durch einen Abnehmer 7 von der Trommel 4 in Form eines Faservlieses 9 abgenommen und einer Auslaufpartie 8 zugeführt. Die Auslaufpartie 8 bewirkt eine Übernahme des Faservlieses 9 vom Abnehmer 7 und führt das Faservlies 9 aus der Karde 1. Die Auslaufpartie 8 umfasst eine Abnahmewalze, welche die Abnahme des Faservlieses vom Abnehmer bewirkt, sowie ein nachfolgendes Quetschwalzenpaar. Anschliessend an die Auslaufpartie, respektive das Quetschwalzenpaar kann das Faservlies einer weitergehenden Behandlung zugeführt oder aufgerollt werden. Zusätzlich kann die Auslaufpartie im Anschluss an ein Quetschwalzenpaar ein quer zum Faservlies verlaufendes Förderband enthalten. Durch ein derartiges Förderband wird das Faservlies zusammengeführt und zu einem Kardenband oder Faserband geformt, welches in Kannen abgelegt werden kann. FIG. 1 shows a side view of a known carding machine 1 in a schematic representation. The fiber material 2 to be carded, which may consist of natural fibers or synthetic fibers or mixtures thereof, is fed into the hopper (not shown) in the form of dissolved and cleaned flakes, taken over by a feed section 3 and transferred to a drum or a drum 4. The inlet section 3 can have a plurality of licker-in rollers and transfers the fiber material 2 taken over as a cotton padding to the drum 4 Fiber material 2 is dissolved on the drum 4 and the individual fibers are parallelized. This process is done by the interaction of drum 4 and traveling deck unit 6, respectively arranged in the carding 5 carding and cleaning elements. After the fibers have partly performed several revolutions on the drum 4, they are removed by a pickup 7 of the drum 4 in the form of a nonwoven fabric 9 and fed to a discharge section 8. The discharge section 8 effects a takeover of the fiber fleece 9 from the taker 7 and guides the fiber fleece 9 out of the carding machine 1. The discharge section 8 comprises a take-off roll, which effects the removal of the fiber fleece from the taker, and a subsequent nip roll pair. Subsequent to the discharge section, or the nip roller pair, the nonwoven fabric can be supplied to a further treatment or rolled up. In addition, following a squeeze roller pair, the outlet section may include a conveyor belt running transversely to the nonwoven fabric. By such a conveyor belt, the nonwoven fabric is brought together and formed into a card sliver or sliver, which can be stored in pots.

Figur 2 zeigt eine schematische Darstellung einer Auslaufpartie einer Karde. Die Fasern werden von einem Abnehmer 7 von der Kardentrommel 4 abgenommen. Ein durch diesen Vorgang gebildetes Faservlies 9 wird durch eine Abnahmewalze 10 vom Abnehmer 7 übernommen und auf einer Vliesleitbrücke 12 abgelegt. Über die Vliesleitbrücke 12 gelangt das Faservlies 9 zu einem nachgeordneten Quetschwalzenpaar 11. Die Vliesleitbrücke 12 ist auf der dem Faservlies 9 zugewandten Seite mit einem Gleitelement 13 versehen. Das Faservlies 9 wird auf der Oberfläche des Gleitelementes 13 geführt. FIG. 2 shows a schematic representation of an outlet part of a card. The fibers are removed from the card drum 4 by a pickup 7. A formed by this process nonwoven fabric 9 is taken over by a take-off roller 10 from the buyer 7 and stored on a Vliesleitbrücke 12. Via the Vliesleitbrücke 12, the nonwoven fabric 9 reaches a downstream nip roller pair 11. The Vliesleitbrücke 12 is provided on the nonwoven fabric 9 side facing with a sliding member 13. The fiber fleece 9 is guided on the surface of the sliding element 13.

Figur 3 zeigt eine schematische dreidimensionale Darstellung einer Vliesleitbrücke 12 mit einem Gleitelement 13. Die Vliesleitbrücke 12 hat eine Längsachse 14. Das Gleitelement 13 ist in der Längsrichtung 14 auf die Vliesleitbrücke 12 aufgeschoben. Durch den dabei erreichten Formschluss zwischen der Vliesleitbrücke 12 und dem Gleitelement 13 wird das Gleitelement13 auf der Vliesleitbrücke 12 gehalten. FIG. 3 shows a schematic three-dimensional representation of a Vliesleitbrücke 12 with a sliding element 13. The Vliesleitbrücke 12 has a longitudinal axis 14. The sliding member 13 is pushed in the longitudinal direction 14 on the Vliesleitbrücke 12. Due to the thereby achieved positive connection between the Vliesleitbrücke 12 and the sliding member 13, the Gleitelement13 is held on the Vliesleitbrücke 12.
