Description

Vliesleitbrücke für eine Karde oder Krempel  Vliesleitbrücke for a card or card
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 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 can also be a subsequent, across the fiber fleece
angeordnetes, Förderband vorgesehen sein, durch welches das Faservlies arranged, conveyor belt be provided, through which the nonwoven fabric
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. is merged 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 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. To eliminate the deposits is a periodic cleaning of the surface of the
Vliesleitbrücke notwendig. Vliesleitbrücke 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. 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. Various constructions of nonwoven guide bridges are known from the prior art. For example, DE 43 28 431 discloses a Vliesleitbrücke which can be inserted from one side into the working position. This allows an expansion 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. 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.

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 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 will thereby also the
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 Possibility created to select and use a corresponding sliding 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
Gleitelementes auf der Vliesleitbrücke können zusätzlich Anschläge oder Sliding element on the Vliesleitbrücke can also attacks or
Sicherungselemente vorgesehen werden. Auch kann das Ende des Gleitelementes entsprechend geformt sein, sodass das Gleitelement nicht über die Vliesleitbrücke hinaus geschoben werden kann. In einer weiteren Ausführungsform ist das Gleitelement auf die Vliesleitbrücke aufgeklipst. Die Montage erfolgt dabei durch eine kurzzeitige Verformung des Fuse elements are provided. Also, the end of the slider can be shaped accordingly, so that the slider can not be pushed over the Vliesleitbrücke addition. In a further embodiment, the sliding element is clipped onto the Vliesleitbrücke. The assembly is carried out by a short-term deformation of the

Das Vorsehen einer Schnappverbindung hat den Vorteil, dass für einen Austausch des Gleitelements kein Werkzeug benötigt wird. Snap device can be provided. 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.
Vorteilhafterweise ist die Vliesleitbrücke als ein Hohlprofil ausgebildet, wodurch sich die Möglichkeit ergibt eine verwind ungssteife Konstruktion bei geringem Gewicht zu realisieren. Die Vliesleitbrücke kann jedoch auch als ein Blech oder eine Stange ausgeführt werden. Advantageously, the Vliesleitbrücke is designed as a hollow profile, which gives the possibility to realize a torsionally rigid construction with low weight. However, the Vliesleitbrücke can also be designed as a sheet or a rod.

Dadurch kann das Gleitelement selbst als Clip ausgeführt werden und es sind keine weiteren In a further embodiment, the sliding element is made of plastic. This allows the slider itself to be executed as a clip and there are no further
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. Fasteners 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 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 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. At this
Verfahrensweise können hochwertige Materialien als Beschichtung genutzt werden, beispielsweise in Form von Folien. Bevorzugterweise findet eine derartige Vliesleitbrücke Anwendung in einer Karde, dabei hat die Karde einen Abnehmer, eine Abnahmewalze und ein Quetschwalzenpaar. Procedure, high-quality materials can be used as a coating, for example in the form of films. Preferably, such Vliesleitbrücke finds application in a card, while the card has a taker, a take-off roll and a pair of nip rollers.
Unterhalb der Abnahmewalze ist zwischen dem Abnehmer und dem Below the take-off roll is between the customer and the
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.
