Description

Die Erfindung betrifft eine Karde mit einem Kardendeckei, sowie mit einer rotierenden, faserführenden Walze, welche mit einer Garnitur versehen ist, sowie mit dieser Walze gegenüberliegenden feststehenden Seitenwänden und mit einem zwischen jeder Seitenwand und der Walze bestehenden, die freie Drehbarkeit der Walze gewährleistenden Spalt.The invention relates to a card with a card cover, and with a rotating, fiber-guiding roller, which is provided with a clothing, and with this roller opposite fixed side walls and with an existing between each side wall and the roller, the free rotation of the roller ensuring gap.

Bei einer Vorrichtung der eingangs genannten Art (z. B. DE-A 2 834 832) ist ein Dichtungsband seitlich der Walze abnehmbar befestigt und überlappt axial frei vorstossend über den Spalt hinweg berührungslos die Zylinderfläche der Walze.In the case of a device of the type mentioned at the beginning (e.g. DE-A 2 834 832), a sealing strip is removably attached to the side of the roller and overlaps the cylinder surface of the roller without contact and axially projecting over the gap.

Durch diese Massnahme wird jedoch nicht ganz verhindert, dass Fasern oder Faserbüschel zwischen Zylinderfläche der Walze und überlappendem Dichtungsband angesammelt werden, respektive dass Fasern oder Faserbüschel durch den Spalt in die Zone innerhalb der Walze gelangen und irgendwo abgelagert werden können. Solche Ablagerungen können je nach Ort der Ablage zwischen stillstehenden und rotierenden Elementen verdichtet und je nach Reibungsintensität in einem unerwünschten Mass erwärmt werden.However, this measure does not entirely prevent fibers or tufts of fibers from accumulating between the cylinder surface of the roller and the overlapping sealing tape, or fibers or fiber tufts from reaching the zone within the roller and being able to be deposited anywhere. Depending on the location of the deposit, such deposits can be compressed between stationary and rotating elements and, depending on the intensity of friction, heated to an undesirable degree.

Es ist deshalb das Ziel der vorliegenden Erfindung, eine Karde zu schaffen, bei welcher Fasern oder Faserbüschel, welche sich am Rand einer mit Garnituren versehenen Walze angesammelt haben, nicht in den Spalt sondern gegen den sich teilweise über die Walze erstreckenden Deckel gegeben werden.It is therefore the object of the present invention to provide a card in which fibers or tufts of fibers which have accumulated on the edge of a roller provided with clothing are not introduced into the nip but against the cover which extends partially over the roller.

Das Ziel wird in der eingangs erwähnten Karde dadurch erreicht, dass an beiden stirnseitigen Endbereichen der Walze je eine innere Fläche Träger eines Abdeckbandes ist, welches die innere Fläche in axialer Richtung der Walze überragt, an einer inneren Fläche der gegenüberliegenden feststehenden Seitenwand dicht anliegt, und dabei den Spalt im wesentlichen abdeckt, sowie dadurch, dass am Endbereich der Walze, ausserhalb der Garnitur, Mittel vorgesehen sind, welche in diesen Bereich gelangte Fasern in Richtung gegen den Kardendeckel fördern.The goal is achieved in the card mentioned at the outset in that an inner surface is supported on each of the two front end regions of the roller, a cover strip which projects beyond the inner surface in the axial direction of the roller, lies tightly against an inner surface of the opposite fixed side wall, and thereby essentially covering the gap, and also in that means are provided at the end region of the roller, outside the clothing, which convey fibers that have reached this region in the direction against the card cover.

Die vorteilhaften Ausführungsformen sind in den weiteren Ansprüchen aufgeführt.The advantageous embodiments are listed in the further claims.

Ein Vorteil der Erfindung liegt darin, dass durch das Befestigen des Abdeckbandes an der Walze keine Reibwärme von der Walze aufgenommen werden muss, sondern dass diese Wärme von der Seitenwand aufgenommen und ohne weiteres an die Umgebungsluft abgegeben werden kann.An advantage of the invention is that by fixing the cover tape to the roller, no frictional heat has to be absorbed by the roller, but that this heat can be absorbed by the side wall and easily released into the ambient air.

Ein weiterer Vorteil ist darin zu sehen, dass das Ersetzen oder Einsetzen des Abdeckbandes ohne Entfernen der Seitenwände durchgeführt werden kann, was erstens wartungstechnisch günstiger ist und zweitens ein Beschädigen des Bandes bei der Montage vermeidet.Another advantage is the fact that the cover tape can be replaced or inserted without removing the side walls, which is firstly less expensive in terms of maintenance and secondly prevents the tape from being damaged during assembly.

Derselbe Vorteil gilt auch für das Ersetzen des Förderstiftes, der im Bereich ausserhalb des Kardendeckels ohne Demontage der Karde in der Walze eingelassen werden kann.The same advantage also applies to the replacement of the conveyor pin, which can be inserted in the area outside the card cover without dismantling the card in the roller.

Im folgenden wird die Erfindung anhand von lediglich Ausführungswege darstellenden Zeichnungen näher erläutert. Es zeigen :

  • Figur 1 eine Karde schematisch in einer Seitenansicht,
  • Figur 2 einen Teil der Karde von Fig. 1 im Schnitt entlang der Linie 11,
  • Figur 3 einen Teil einer Walze einer Karde,
  • Figur 4 ein erfindungsgemässes Element der Karde,
  • Figuren 5-6 je einen Ausschnitt aus zwei Teilen der Karde mit erfindungsgemässen Elementen.
In the following, the invention is explained in more detail with the aid of drawings which only show execution routes. Show it :
  • FIG. 1 shows a card in schematic side view,
  • FIG. 2 shows part of the card of FIG. 1 in section along line 11,
  • FIG. 3 shows part of a roller of a card,
  • FIG. 4 an element of the card according to the invention,
  • Figures 5-6 each a section of two parts of the card with elements according to the invention.

In einem Gestell 1 einer Karde 2 sind eine Speisewalze 3, eine Vorreisserwalze 4, eine Hauptwalze oder Tambour 5 und eine Abnehmerwalze 6 in nicht besonders dargestellter Weise drehbar und antreibbar gelagert. Ueber dem Tambour 5, der auf seiner Zylinderfläche 7 mit einer Garnitur 8 bestückt ist, befindet sich ein Kardendeckel 9 mit Spitzen 9a (Fig. 2), so dass Fasermaterial (nicht gezeigt) zwischen den Spitzen 9a und der Garnitur 8 in an sich bekannter Weise bearbeitet werden kann. An der jeweiligen Stirnseite 10 (Fig. 1) des Tambours 5 ist eine Seitenwand 11 vorgesehen, die mittels Flanschen 12 am Gestell 1 befestigt ist. Die Seitenwand 11 reicht mit einem Seitenwandteil 11a bis in die Nähe der Zylinderfläche 7 und einer Stirnfläche 13 (Fig. 5) eines Spaltes 14, dessen Weite a die freie Drehbarkeit des Tambours 5, z. B. auch bei Lagerspiel desselben gegenüber dem Seitenwandteil 11a gewährleistet. Zwischen dem Seitenwandten 11a und einem parallel zu diesem sich erstreckenden Seitenwandteil 11b ist ein flexibler, kreisförmig gekrümmter Bogen 15 einstellbar angeordnet, der zur präzisen Führung der Deckel 9 entlang des Tambours 5 dient.In a frame 1 of a card 2, a feed roller 3, a licker-in roller 4, a main roller or drum 5 and a take-off roller 6 are rotatably and drivably mounted in a manner not particularly shown. Above the drum 5, which is fitted with a clothing 8 on its cylindrical surface 7, there is a card cover 9 with tips 9a (FIG. 2), so that fiber material (not shown) between the tips 9a and the clothing 8 is known per se Way can be edited. On the respective end face 10 (FIG. 1) of the drum 5, a side wall 11 is provided, which is fastened to the frame 1 by means of flanges 12. The side wall 11 extends with a side wall part 11a into the vicinity of the cylinder surface 7 and an end face 13 (FIG. 5) of a gap 14, the width a of which allows the drum 5 to rotate freely, e.g. B. also guaranteed with bearing play of the same with respect to the side wall part 11a. Between the side wall 11a and a side wall part 11b extending parallel thereto, a flexible, circularly curved arc 15 is adjustably arranged, which serves for the precise guidance of the cover 9 along the drum 5.

Zur Abdeckung des Spaltes 14 ist ein textiles Abdeckband 16, z. B. ein Filzband, vorgesehen, welches mittels eines Spannbandes 17 (Fig. 2, 4 und 5) gegen eine innere Fläche 18 des Tambours 5 gepresst wird. Dadurch ist das Abdeckband 16 fest mit dem Tambour 5 verbunden. Das Abdeckband 16 reicht dabei über den Spalt 14 hinaus und liegt an einer inneren Reibfläche 19 des Seitenwandteiles 11a an.To cover the gap 14, a textile masking tape 16, for. B. a felt band is provided, which is pressed by means of a tension band 17 (Fig. 2, 4 and 5) against an inner surface 18 of the drum 5. As a result, the cover tape 16 is firmly connected to the drum 5. The cover strip 16 extends across the gap 14 and lies at an inner friction surface 19 of the Se i tenwandteiles 11a.

Der Anspressdruck des Abdeckbandes 16 an dieser Reibfläche 19 ist je nach Differenz A R der beiden Radien R1 und R2 (Fig. 5) und je nach Elastizität des Abdeckbandes unterschiedlich gross. Die Differenz A R und die Elastizität des Abdeckbandmaterials ist so gewählt, dass bei Rotation des Tambours 5 eine schleifende Dichtung ohne wesentliche Erwärmung entsteht.The contact pressure of the cover tape 16 on this friction surface 19 is different depending on the difference A R of the two radii R1 and R2 (FIG. 5) and depending on the elasticity of the cover tape. The difference A R and the elasticity of the masking tape material is selected so that when the drum 5 rotates, a sliding seal is produced without substantial heating.

Damit das Spannband 17 seine Spannfunktion ausüben kann, ist an den beiden Bandenden eine Lasche 20 resp. 21 (Fig. 4) befestigt. Die Lasche 20 nennen wir Drucklasche und die Lasche 21 Gewindelasche. Die Gewindelasche 21 weist, zur Aufnahme eines Gewindebolzens 22, eine Gewindebohrung (nicht gezeigt) auf. Eine Gegenmutter 23 fixiert den Gewindebolzen 22 in der Gewindebohrung.So that the strap 17 can perform its tensioning function, a tab 20 is at the two ends of the strap. 21 (Fig. 4) attached. We call the tab 20 a pressure tab and the tab 21 a threaded tab. The threaded tab 21 has a Ge for receiving a threaded bolt 22 wind bore (not shown). A lock nut 23 fixes the threaded bolt 22 in the threaded bore.

Die Montage des Abdeckbandes 16 zusammen mit dem Spannband 17 geschieht dadurch, dass das geöffnete Band mit einem Ende voraus durch eine Montageoeffnung 24 resp. 25 in den Wandteilen 11b resp. 11 geschoben wird, bis das ganze Band an den genannten Flächen 18 und 19 angelegt werden kann. Anschliessend wird durch Drehung des Gewindebolzens 22 das Band gegen die vorgenannten Flächen 18 und 19 gepresst.The assembly of the cover band 16 together with the tension band 17 is done in that the opened band with one end ahead through a mounting opening 24 or. 25 in the wall parts 11b respectively. 11 is pushed until the entire band can be placed on the surfaces 18 and 19 mentioned. The tape is then pressed against the aforementioned surfaces 18 and 19 by rotating the threaded bolt 22.

Mit dem Abdeckband 16 wird im wesentlichen verhindert, dass Luft durch den Spalt 14 strömt und ist damit eine Massnahme, um möglichst zu verhindern, dass Fasern oder Faserbüschel, die über den Rand 26 der Garnitur 8 gefördert werden, in den Spalt 14 gelangen können.The masking tape 16 essentially prevents air from flowing through the gap 14 and is therefore a measure to prevent as far as possible that fibers or tufts of fibers that are conveyed over the edge 26 of the clothing 8 can get into the gap 14.

Um gegebenenfalls trotz vorgenannter Massnahme in den Spalt gelangte Faserbüschel wieder an die Oberfläche zu schaffen, ist in der Stirnfläche 13, resp. in der dieser gegenüberliegenden Fläche 27 eine Fördernute 28 resp. 29 vorgesehen. Dabei sind dazugehörige Förderflächen 30 resp. 31 derart gekreuzt und durch die kleine Spaltbreite a von ca. 1 mm derart nahe einander gegenüberliegend, dass bei Rotation des Tambours Faserbüschel durch die Scherenwirkung der beiden Förderflächen 30 resp. 31 wieder an die Oberfläche gefördert werden.In order to create tufts of fibers that may have come into the gap despite the aforementioned measure, in the end face 13, respectively. in the surface 27 opposite this a conveying groove 28 or. 29 provided. Associated funding areas 30 and. 31 crossed in such a way and because of the small gap width a of about 1 mm so close to each other that when the drum is rotated, the tufts of fibers are sheared by the two conveying surfaces 30 and 30, respectively. 31 are promoted to the surface again.

Eine weitere Massnahme dient der Förderung der genannten Faserbüschel gegen die Spitzen 9a des Kardendeckeis 9.Another measure serves to promote the tufts of fibers mentioned against the tips 9a of the card cover 9.

. Diese Massnahme umfasst mindestens einen in der sich zwischen der Stirnfläche 13 und dem Garniturrand 26 erstreckenden Oberfläche 32 eingelassenen Förderstift 33 (Fig. 2 und 3). Dabei ist, um die Förderwirkung zu optimieren, der Förderstift in axialer Richtung des Tambours gesehen, mit einem Winkel a (Fig. 2) von ca. 30° Winkelgraden gegen die Seitenwand 11 hin geneigt und, in der Drehrichtung D des Tambours 5 gesehen, mit einem Winkel ß (Fig. 3) von ca. 3° Winkelgraden rückwärts, von einer Radialen R3 aus gemessen, geneigt im Tambour 5 eingelassen. . This measure comprises at least one conveyor pin 33 embedded in the surface 32 extending between the end face 13 and the clothing edge 26 (FIGS. 2 and 3). In order to optimize the conveying effect, the conveying pin is seen in the axial direction of the reel, is inclined at an angle a (FIG. 2) of approximately 30 ° to the side wall 11 and, viewed in the direction of rotation D of the reel 5, with an angle β (FIG. 3) of approximately 3 ° degrees backwards, measured from a radial R3, inclined in the drum 5.

Alle drei Massnahmen sind beiderseits des Tambours 5 vorgesehen.All three measures are provided on both sides of the drum 5.

Eine mit Fig. 6 gezeigte Variante weist einen sich in radialer Richtung öffnenden, den Spalt 14 ersetzenden Spalt 34 auf, der durch eine zur Walze 5 gehörenden schräg vorgesehenen Stirnfläche 35 und durch eine zur Seitenwand 11a gehörende, ebenfalls schräg vorgesehene Stirnfläche 36 gebildet wird. In der Stirnfläche 35 ist ein Förderstift 37 derart schräg eingesetzt, dass dieser in Relation zur Walze 5 in denselben Neigungen angeordnet ist, wie der Stift 33.A variant shown in FIG. 6 has a gap 34 which opens in the radial direction and replaces the gap 14 and which is formed by an obliquely provided end face 35 belonging to the roller 5 and by a likewise provided obliquely provided end face 36 belonging to the side wall 11a. A conveyor pin 37 is inserted obliquely in the end face 35 such that it is arranged in relation to the roller 5 at the same inclinations as the pin 33.

Im weiteren ist der Stift 37, etwa in der in Fig 6 gezeigten Relation nahe an dem Abdeckband 16 angeordnet.Furthermore, the pin 37 is arranged close to the masking tape 16, approximately in the relation shown in FIG. 6.

Die mit Fig. 6 gezeigte Variante ist ebenfalls beiderseits der Walze 5 vorgesehen.The variant shown in FIG. 6 is also provided on both sides of the roller 5.

Der Förderstift 33 resp. 37 kann ohne Entfernen der entsprechenden Seitenwand 11, d. h. ohne Demontage der Karde 2, im Bereich ausserhalb des Kardendeckeis 9 ersetzt resp. eingesetzt werden.The funding pin 33, respectively. 37 can be removed without removing the corresponding side wall 11, i.e. H. without dismantling the card 2, in the area outside the card deck 9 replaced or be used.
