Description

Karde teasel
Die Erfindung betrifft eine Karde mit einer Trommel und einem, eine Arbeitsbreite der Trommel überspannendes Arbeitselement, welches auf beiden Seiten ausserhalb der Arbeitsbreite ortsfest gelagert ist, wobei die Trommel mit einer Garnitur versehen ist, welche dem Arbeitselement gegenübersteht und dabei ein sich zwischen der Garnitur der Trommel und dem Arbeitselement befindlicher Raum bildet; sowie ein Arbeitselement und ein Einstellverfahren.The invention relates to a card with a drum and, a working width of the drum spanning working element, which is mounted stationary on both sides outside the working width, wherein the drum is provided with a clothing which faces the working element and thereby a between the clothing of the Drum and the working element located space forms; and a working element and a setting method.
In einer Karde sind über den Umfang der Trommel verteilt verschiedenen Arbeitselemente ortsfest angeordnet. Diese Arbeitselemente dienen der Auflösung der Flocken zu Einzelfasern, der Ausscheidung von Verunreinigungen und Staub, der Eliminierung von sehr kurzen Fasern, der Auflösung von Nissen und der Parallelisierung der Fasern, sowie der Führung der Fasern während eines Trommelumlaufs. Beispielsweise werden als ortsfeste Arbeitselemente Messer oder Abdeck- und Führungselemente oder mit Garnituren versehene Deckel eingesetzt.In a carding machine, distributed over the circumference of the drum different work elements are stationary. These working elements are used to dissolve the flakes into individual fibers, remove impurities and dust, eliminate very short fibers, dissolve nits and parallelize the fibers, and guide the fibers during drum rotation. For example, knives or covering and guiding elements or lids provided with covers are used as stationary working elements.
Die Breite respektive derjenige Teil der axialen Länge der Trommel, welcher mit einer Garnitur belegt ist bildet die Arbeitsbreite der Karde. Über diese Arbeitsbreite formt sich zwischen der Garnitur der Trommel und dem jeweiligen Arbeitselement ein Raum. An der engsten Stelle dieses Raums entsteht dabei ein schmaler Spalt. Die Arbeitselemente überspannen die gesamte Arbeitsbreite der Trommel und sind an ihren beiden Enden an den beidseits der Trommel angeordneten Trommelschilde befestigt.The width or the part of the axial length of the drum, which is covered with a set forms the working width of the card. About this working width formed between the clothing of the drum and the respective working element a space. At the narrowest point of this space, a narrow gap is created. The working elements span the entire working width of the drum and are attached at both ends to the drum shields arranged on both sides of the drum.
Der zwischen der Garnitur der Trommel und dem jeweiligen Arbeitselement vorhandene Raum respektive Spalt ist bedingt durch verschiedene Einflüsse während des Betriebs der Karde über die Arbeitsbreite der Deckel nicht konstant. Aufgrund der sich ändernden Betriebsverhältnisse im Bereich des Spaltes resp. des Raumes, wie beispielsweise die Temperaturverhältnisse, die mechanische Beanspruchung der Garnitur oder des Arbeitselementes oder die auf die Arbeitselemente oder die Trommel wirkenden Kräfte wie Zentrifugal- oder Schwerkraft. Durch den Einfluss der während des Betriebs stei- genden Temperatur im Bereich des Raumes erfolgt eine Ausdehnung der Trommel und auch des Arbeitselementes.The existing between the set of the drum and the respective working element space or gap is not constant due to various influences during the operation of the card over the working width of the lid. Due to the changing operating conditions in the region of the gap resp. space, such as the temperature conditions, the mechanical stress on the clothing or the working element or the forces acting on the working elements or the drum forces such as centrifugal or gravitational force. Due to the influence of the increase during operation ing temperature in the area of the space is an expansion of the drum and also the working element.
Diesen Einflüssen wurde in der Vergangenheit versucht durch verschiedene Massnah- men zu begegnen.In the past, these influences have been tried to counter by various measures.
Die DE 20 2007 002 975 offenbart ein System, bei welchem zwischen den Lagerungspunkten des Arbeitselementes Stellmittel vorgesehen sind, die eine Einstellung des Raumes respektive Spaltes zwischen der Trommel und dem Arbeitselement über den Verlauf der Arbeitsbreite ermöglichen. Das Arbeitselement wird dabei mit Hilfe des Stellmittels im Abstand zu einem darüber liegenden starren Element verstellt. Ein Nachteil dieser Lösung ist, dass ein zusätzliches Element oberhalb des Arbeitselementes auf der, der Trommel gegenüberliegenden Seite des Arbeitselementes vorgesehen werden muss. Dieses zusätzliche Element muss zudem derart ausgeführt sein, dass sich bei Verstellung des Stellmittels das Arbeitselement und nicht das Zusatzelement verformt.DE 20 2007 002 975 discloses a system in which actuating means are provided between the bearing points of the working element, which allow adjustment of the space or gap between the drum and the working element over the course of the working width. The working element is adjusted by means of the adjusting means at a distance to an overlying rigid element. A disadvantage of this solution is that an additional element above the working element on the, the drum opposite side of the working element must be provided. This additional element must also be designed such that deforms when adjusting the actuating means, the working element and not the additional element.
Die DE 10 2006 014 419 A1 offenbart ein System, welches durch die Zufuhr von Energie, im speziellen Wärme, versucht eine Gegenbewegung zur betriebsbedingten Verformung der Arbeitselemente zu erreichen. Durch die damit mögliche Änderung der Kontur des Arbeitselements soll ein gleichbleibender Spalt während sich ändernder Be- triebsverhältnisse erreicht werden. Das System hat den Nachteil, dass eine durch Wärme erreichte Konturänderung träge vor sich geht. . Zudem ist die Voraussage der zu erwartenden Veränderung der Form bei Einwirkung von Wärmeenergie schwierig und stark abhängig von den spezifischen Eigenschaften eines jeden einzelnen Arbeitselements. Ausserdem ergibt sich aus einer Zuführung von Wärmeenergie der Nachteil, das der Wärmehaushalt der Karde und des Arbeitselementes selbst verändert wird, was wiederum zu einer unerwünschten Beeinflussung von anderen Bauteilen führen kann.DE 10 2006 014 419 A1 discloses a system which, by supplying energy, in particular heat, attempts to achieve a countermovement to the operational deformation of the working elements. By thus changing the contour of the working element a constant gap should be achieved during changing operating conditions. The system has the disadvantage that a contour change achieved by heat is slow. , In addition, the prediction of the expected change in shape when exposed to thermal energy is difficult and highly dependent on the specific properties of each individual working element. In addition, it results from a supply of heat energy the disadvantage that the heat balance of the carding and the working element itself is changed, which in turn can lead to an undesirable influence of other components.
Der Erfindung liegt die Aufgabe zugrunde, eine Karde der eingangs beschriebenen Art zu schaffen, welche die genannten Nachteile vermeidet und einen an die Betriebsver- hältnisse über die gesamte Arbeitsbreite der Karde angepassten Raum zwischen Trommel-Garnitur und Arbeitselementen ermöglicht. Die Aufgabe wird gelöst durch die Merkmale im kennzeichnenden Teil der unabhängigen Ansprüche. Zur Lösung der Aufgabe wird vorgeschlagen eine Karde vorzusehen, bei welcher Mittel zur Erzeugung einer Stellkraft zur Einstellung des Raumes zwischen der Trommel-Garnitur und einem, mit der Trommel-Garnitur zusammenarbeitenden, Arbeitselement in seinem Verlauf über die Arbeitsbreite vorgesehen sind, wobei die Mittel innerhalb des Arbeitselements angeordnet sind und die Stellkraft eine magnetische Kraft ist.The invention has for its object to provide a card of the type described above, which avoids the disadvantages mentioned and allows the operating conditions over the entire working width of the card adjusted space between drum set and work items. 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 card in which means for generating a force for adjusting the space between the drum set and a cooperating with the drum set, working element are provided in its course over the working width, wherein the means within of the working element are arranged and the force is a magnetic force.
Die Arbeitselemente werden mit Hilfe einer neuen Vorrichtung dahingehend beeinflusst, dass durch die Erzeugung mindestens einer Stellkraft eine Verformung des Arbeitselementes erreicht werden kann. Dabei wird es möglich, dass auf den Wanderdeckel eine durch eine Einstellvorrichtung eingebrachte Stellkraft wirkt, die ein Einstellen des Spaltes respektive Raums zwischen der Trommel-Garnitur und dem Arbeitselement im Verlauf der Arbeitsbreite aufgrund der Herstellung und Einstellung einzelner Bauteile oder sich ändernder Betriebsverhältnisse ermöglicht. Die Herstell- und Einstelldaten eines Bauteils oder die sich ändernden Betriebsverhältnisse können anhand von Betriebsparametern angegeben werden. Solche Betriebsparameter sind beispielsweise die Umgebungsbedingungen (Temperatur, Druck, Luftfeuchtigkeit), die Eigenschaften und Zustände eines Bauteils (Temperatur, Herstellung, Verschleiss), die Eigenschaften des zu verarbeitenden Materials oder auch die zu erreichenden oder die aktuellen Betriebswerte (Produktionsmenge, Kardierqualität). Die Einstellvorrichtung ist dabei in das Arbeitselement integriert. Die Arbeitselemente wie Kardierelemente, Messer oder Abdeck- und Führungselemente heutiger Wanderdeckelkarden werden in der Regel an den Trommelschilden beidseitig der Trommel ortsfest gelagert. Die Trommelschilde sind ausser- halb der Arbeitsbreite, welche der Breite oder axialen Länge des garnierten Bereichs der Trommel entspricht angeordnet. Die Arbeitselemente überspannen zwischen diesen Trommelschilden die Trommel auf ihrer gesamten Arbeitsbreite. Heute zur Anwendung kommende Karden weisen eine Arbeitsbreite von über 1000 mm, meist über 1200 mm, vorzugsweise 1500 mm auf.The working elements are influenced by means of a new device to the effect that by generating at least one actuating force, a deformation of the working element can be achieved. It is possible that on the revolving lid an adjusting force introduced by an adjusting device acts, which allows adjusting the gap or space between the drum set and the working element in the course of the working width due to the production and adjustment of individual components or changing operating conditions. The manufacturing and adjustment data of a component or the changing operating conditions can be specified on the basis of operating parameters. Such operating parameters are, for example, the ambient conditions (temperature, pressure, atmospheric humidity), the properties and conditions of a component (temperature, production, wear), the properties of the material to be processed or the achievable or the current operating values (production volume, carding quality). The adjusting device is integrated in the working element. The working elements such as carding, knife or cover and guide elements of today's Wanderdeckelkarden are usually stored on the drum shields on both sides of the drum stationary. The drum shields are located outside the working width corresponding to the width or axial length of the garnished portion of the drum. The working elements span between these drum shields the drum over its entire working width. Carding machines used today have a working width of more than 1000 mm, usually more than 1200 mm, preferably 1500 mm.
In einer ersten erfindungsgemässen Ausführung eines Arbeitselementes wird im Arbeitselement mindestens ein Magnet in der Bauart eines Permanentmagneten vorgese- hen. Durch den Permanentmagneten wird ein Magnetfeld aufgebaut, welches in seiner Stärke vom Magneten selbst und von seiner Lage abhängig ist. Wird die Lage des Magneten verändert, ändert sich auch die Lage des Magnetfeldes und damit der Ein- fluss auf die innerhalb des Magnetfeldes angeordneten magnetischen Körper. Der Auf- bau des Magnetfeldes wird derart ausgerichtet, dass die Trommel in den Einflussbereich des Feldes gerät, wodurch zwischen dem Arbeitselement und der Trommel eine Anziehungskraft erzeugt wird. Diese Anziehungskraft wird als Stellkraft für das Arbeitselement genutzt, die zu einer Verformung des Arbeitselementes führt. Durch Veränderung der Lage des Magneten wird die Stellkraft verändert. Die Veränderung der Lage des Magneten kann mechanisch erfolgen, beispielsweise durch Drehung des Magneten. Die Grosse der Lageveränderung wird von einer Steuerung ausserhalb des Arbeitselementes aufgrund der herrschenden Betriebsparameter bestimmt.In a first embodiment of a working element according to the invention, at least one magnet in the design of a permanent magnet is provided in the working element. hen. Through the permanent magnet, a magnetic field is built up, which is dependent on the strength of the magnet itself and its location. If the position of the magnet is changed, the position of the magnetic field and thus the influence on the magnetic body arranged within the magnetic field also change. The build-up of the magnetic field is oriented such that the drum comes into the area of influence of the field, whereby an attraction force is generated between the working element and the drum. This attraction is used as a force for the working element, which leads to a deformation of the working element. By changing the position of the magnet, the force is changed. The change in the position of the magnet can be done mechanically, for example by rotation of the magnet. The size of the change in position is determined by a control outside the working element due to the prevailing operating parameters.
In einer weiteren Ausführung der Vorrichtung wird im Arbeitselement mindestens ein Elektromagnet oder eine Kombination von Permanent- und Elektromagnet eingebaut. Durch den Elektromagneten wird ein magnetisches Feld aufgebaut respektive ein durch den Permanentmagneten aufgebautes Feld verstärkt oder verändert, welches in seiner Stärke abhängig ist von der Stromversorgung des Elektromagneten. In Abhängigkeit vom Abstand der Magneten zur Trommel sowie der Umgebung der Magneten wird das Arbeitselement zur Trommel mehr oder weniger stark hingezogen. Dadurch wird das Arbeitselement entsprechend verformt, was sich in einer Veränderung der Geometrie des Raumes zwischen der Trommel-Garnitur und dem Arbeitselement niederschlägt. Der Einbauort im Arbeitselement ist abhängig von der Bauart des Arbeitselementes. Eine Steuerung der elektrischen Versorgung des Elektromagneten ermöglicht die Ver- formung des Arbeitselementes zu steuern oder zu regeln. Eine solche Regelung kann abhängig von verschiedenen Betriebsparametern ausgeführt werden.In a further embodiment of the device, at least one electromagnet or a combination of permanent magnet and electromagnet is installed in the working element. By the electromagnet, a magnetic field is constructed or amplified by the permanent magnet field built up or changed, which is dependent on the power of the electromagnet in its strength. Depending on the distance of the magnets to the drum and the environment of the magnets, the working element is attracted to the drum more or less strongly. As a result, the working element is deformed accordingly, which is reflected in a change in the geometry of the space between the drum set and the working element. The installation location in the working element depends on the design of the working element. A control of the electrical supply of the electromagnet allows the deformation of the working element to be controlled or regulated. Such a control can be carried out depending on various operating parameters.

Figur 1 zeigt in einer Seitenansicht eine an sich bekannte Wanderdeckelkarde 1 in schematischer Darstellung. Die zu kardierenden Faserflocken 2, die aus Naturfasern oder synthetischen Fasern oder Mischungen derselben bestehen können, werden in Form von aufgelösten und gereinigten Flocken in den Füllschacht (nicht gezeigt) eingespeist, von einem Briseur bzw. einem Vorreisser 3 als Wattenvorlage übernommen und einem Tambour bzw. einer Trommel 4 übergeben. Die Flocken werden auf der Trommel 4 aufgelöst, gereinigt und parallelisiert. Dieser Vorgang geschieht durch das Zusammenwirken von Trommel 4 und verschiedenen ortsfesten Arbeitselementen 7, 8, 9, 10 und einem Wanderdeckelaggregat 5, welches Wanderdeckel 6 einem Teil des Umfangs der Trommel 4 entlang führt. Ortsfeste Arbeitselemente sind beispielsweise Kardierele- mente 7, Messer 8 und Führungs- oder Abdeckelemente 9, 10. Je nach Einsatzgebiet einer Karde 1 kommen verschieden grosse oder auch mehrere am Umfang der Trommel 4 verteilte Arbeitselemente 7, 8, 9, 10 zum Einsatz.Figure 1 shows a side view of a known Wanderdeckelkarde 1 in a schematic representation. The fiber flakes 2 to be carded, which may consist of natural fibers or synthetic fibers or mixtures thereof, are fed into the hopper (not shown) in the form of dissolved and cleaned flakes, taken over by a buffurizer or a licker-in 3 as a wadding template and a drum or tambour Pass a drum 4. The flakes are dissolved on the drum 4, cleaned and parallelized. This process is done by the interaction of drum 4 and various stationary working elements 7, 8, 9, 10 and a revolving flat 5, which revolving lid 6 a portion of the circumference of the drum 4 along. Stationary work elements are, for example, carding elements 7, knives 8 and guide or cover elements 9, 10. Depending on the field of use of a carding machine 1, differently sized or multiple work elements 7, 8, 9, 10 distributed on the circumference of the drum 4 are used.
Die Fasern bilden das sich auf der Trommel 4 befindliche Faservlies, welches dann von einer Abnehmerwalze 11 abgenommen und in an sich bekannter Weise in einer, aus verschiedenen Walzen bestehenden, Auslaufpartie 12 zu einem Kardenband 13 geformt wird. Dieses Kardenband 13 wird dann von einer Bandablage (nicht gezeigt) in einer Transportkanne in zykloidischer Art abgelegt.The fibers form the non-woven fabric located on the drum 4, which is then removed from a doffer roller 11 and formed in a conventional manner in a, consisting of different rolls, discharge section 12 to a card sliver 13. This card sliver 13 is then deposited by a sliver tray (not shown) in a transport can in a cycloidal manner.
