Definitions
- the present invention relates to a storage of a flexible bend in a revolving flat card.
- the lid area together with the drum forms the main carding zone and has as function the dissolution of the flakes into single fibers, removal of impurities and dust, elimination of very short fibers, the dissolution of nits and the parallelization of the fibers.
- hard covers, revolving lids or a mixture of fixed and revolving lids are used.
- a revolving lids or a mixture of hard covers and revolving lids one speaks of a revolving flat card. Between the sets of covers and the clothing of the drum forms a narrow gap called the carding nip.
- revolving lids by the revolving lids, guided by arcuate strips - so-called flexible arch, Regulierbogen, Flexbogen or Gleitbogen - are guided along a predetermined distance by these strips in the circumferential direction of the drum.
- the size of the carding nip lies with a revolving flat card between 0.10 to 0.30 mm for cotton or up to 0.40 mm for man-made fibers.
- the flexible bend is secured with adjusting screws on the machine frame.
- the adjustment screws allow for a concentric adjustment of the flexible arch surface so that the traveling lids can be kept at a constant distance along the drum surface.
- the setting accuracy depends on the design of the adjusting screws.
- the EP 1 201 797 has proposed a device for adjusting the carding gap, in which the flexible sheet is supported on rotatably mounted rollers.
- the rollers are designed as rotatable helical cams. Upon rotation of these cams is raised by the worm shape of the flexible bend at the corresponding support point and in the radial direction away from the drum axis or to these. In this way, a coarse adjustment of the carding nip is proposed.
- the flexible sheet itself is moved in the drum rotation direction, which causes the radial distance of the flexible sheet to change from the drum axis.
- a disadvantage of the device is that the entire flexible sheet must be moved to adjust the carding gap. In particular, the fine adjustment is provided by the movement of the flexible bend, which is associated with a considerable expenditure of force and thus only jerking can be performed.
- the invention of the present application has for its object to provide a storage of a flexible arch which allows an adjustment of the carding at a single bearing point, as well as an adjustment of the carding at all bearing points of the flexible sheet together, both types of adjustment to use the same adjustment and wherein the adjustment of a single bearing should be possible without affecting the common adjustment.
- a storage of a flexible sheet is proposed in a revolving flat card with a drum and a drum axis, wherein the bearing comprises at least three bearings, each with a bearing pin and an adjusting lever.
- the flexible sheet is held at each bearing point on the respective bearing pin, that during a rotational movement of the bearing pin of the flexible sheet is moved radially to the drum axis.
- the bearing pin has a bearing pin axis, a mounting portion, a movement portion and a support surface for the support of the flexible sheet, while the support surface is formed by a spiral around the bearing pin axis arranged surface.
- bearings For the support of a flexible arch several support points, so-called bearings are provided.
- the number of bearings depends on the design of the flexible sheet, in particular its length.
- the bearings may be arranged symmetrically or asymmetrically with respect to the flexible arch.
- more than three bearing points for example five or seven bearing points, are necessary.
- the storage of the flexible sheet is done so that the sliding on it Travel lids are guided in the desired type of drum surface along.
- the flexible bend is held by a bolt at each bearing point.
- the bolt itself is rotatably mounted in the machine frame of Wanderdeckelkarde, this, the bolt on a mounting portion.
- the attachment portion of the bolt is designed such that adjoins the movement portion on one side of the attachment portion and on the other side of the attachment portion, the support surface for the flexible bend.
- the attachment portion is arranged in the direction of the bearing pin axis between the movement portion and the support surface.
- the attachment portion is bisected by the support surface disposed within the attachment portion. The bearing pin is thereby held in two places in the machine frame, wherein between these two points the support surface for the flexible sheet is arranged. This has the advantage that the bearing points of the bearing pin is stressed only by forces in one direction and no torques occur. In a one-sided storage act on the bearing bolt in addition bending forces, which can be avoided by a two-part mounting portion.
- the bearing surface is spirally applied around the bearing pin axis.
- the radial distance of the support surface changes by a certain amount, which is dependent on the spiral shape of the support surface.
- the usable bearing surface does not extend over the entire circumference of the bearing pin due to the helical design.
- the flexible sheet can be changed in its distance from the drum axis in a range of 2 to 10 mm. This change in the radial distance of the flexible sheet from the drum axis corresponds to the necessary change in the distance of the support surface from the bearing pin axis.
- the distance of the bearing surface from the bearing pin axis likewise changes by 2 to 10 mm.
- the spiral shape is, for example, created such that the change in the distance during at least half the circumference of the bearing pin results.
- the radial distance of the bearing surface of the bearing pin axis thus changes, for example, by an amount of 2 to 10 mm with a rotation of the bearing pin by 180 °.
- a change in the distance of 4 to 8 mm is to be striven for, as has shown a particularly advantageous change in the distance of 6 mm.
- the spiral shape of the support surface is an Archimedean spiral.
- An Archimedean spiral has a continuous slope. This has the advantage that the rotation of the bearing pin by a certain angle always causes the same change in the radial distance of the support surface, regardless of the position of the bearing pin.
- the flexible sheet on a bearing surface of the bearing pin facing side has a support surface which is formed as a plane
- the flexible sheet is located tangentially on the spiral bearing surface of the bearing pin.
- the line of movement along which the rotation of the bearing pin, the displacement of the flexible sheet is therefore not identical to the perpendicular to the tangent on which the flexible sheet rests.
- the perpendicular to the tangent of the support point of the flexible bend is at a certain angle to the displacement line along which the flexible bend by the rotation of the bearing pin is moved.
- the spiral shape of the support surface of the bearing pin to provide such that, despite the difference between the support point of the flexible sheet on the bearing pin and the line of movement, a linear dependence between the rotation angle of the bearing pin and the distance ( A) exists between the bearing pin axis and the flexible bend in the direction of movement of the flexible bend.
- the adjusting lever is held on the moving portion of the bearing pin.
- the adjusting lever is rotatably held on the bearing pin with a releasable locking.
- the lock comprises a locking screw and a two-piece clamping bolt.
- the clamping bolt is aligned in its shape along its longitudinal axis at least on one side of the shape of the bearing pin. Now, if the two halves of the clamping bolt pulled together, this causes a distortion of the clamping bolt against the bearing pin.
- a device which allows rotation of the bearing pin independent of the adjusting lever and independently of the other respective bearing points.
- the movement portion of the bearing pin is provided at least partially with a toothing on its circumference.
- an adjusting member is provided in the adjusting lever, which forms a reduction stage (such as a worm drive) with the toothing on the circumference of the bearing pin. With the adjustment can thus over the reduction stage of the bearing pin set in rotation and thus the flexible sheet are brought into the desired basic position.
- the adjusting lever is in turn rotatably connected via the lock with the adjusting lever.
- the adjusting levers of the individual bearings are connected to a common slider. This connection causes the adjustment lever and the lock and the bearing pin are held against rotation.
- the holder of the adjusting lever in the slide is designed via a arranged in the slide radially aligned guide. On the adjusting lever a guide pin is provided, which engages in the guide groove. If the slider is now moved tangentially to the drum axis, this movement is transmitted via the guide pins on the adjusting lever and leads to a rotation of the adjusting lever about the bearing pin axis. By locking the adjusting lever on the bearing pin, the rotation of the adjusting lever is transmitted to the bearing pin. As a result, by the rotation of the bearing pin of the flexible bend in all bearings simultaneously and due to the spiral bearing surface of the bearing pin in all bearings shifted by the same amount radially. The shift is independent of the current individual setting of the individual bearings.
- the slide is provided with a drive.
- a drive This allows automatic adjustment of the flexible bend by a central control.
- the tangential movement of the slider is in a fixed relationship to the displacement of the flexible bend.
- the movement of the slider is translated, whereby a large movement of the slider leads to a small displacement of the flexible bend. This allows a high accuracy in the adjustment of the flexible sheet in steps of less than 0.01 mm.
- a cover actuator can be operated with the aid of the slide.
- a lid actuator is used for automatic adjustment of the carding gap between the revolving lids and the drum of a card. If the trimmings of the drum or the sets of the revolving cover are reground, for example, this change in the carding gap is detected by the measuring device of the controller and compensated automatically via the slide.

Description
Die vorliegende Erfindung betrifft eine Lagerung eines Flexibelbogens in einer Wanderdeckelkarde.The present invention relates to a storage of a flexible bend in a revolving flat card.
In einer Karde bildet der Deckelbereich zusammen mit der Trommel die Hauptkardierzone und hat als Funktion die Auflösung der Flocken zu Einzelfasern, Ausscheidung von Verunreinigungen und Staub, Eliminierung von sehr kurzen Fasern, die Auflösung von Nissen und die Parallelisierung der Fasern. Je nach Anwendung einer Karde werden dabei Festdeckel, Wanderdeckel oder eine Mischung aus Fest- und Wanderdeckel eingesetzt. Bei einem Einsatz von Wanderdeckeln oder einer Mischung von Festdeckeln und Wanderdeckeln spricht man von einer Wanderdeckelkarde. Zwischen den Garnituren der Deckel und der Garnitur der Trommel formt sich ein enger Spalt, der Kardierspalt genannt wird. Er ergibt sich beim Einsatz von Wanderdeckeln indem die Wanderdeckel, geführt durch bogenförmige Leisten - sogenannte Flexibelbogen, Regulierbogen, Flexbogen oder Gleitbogen -, in einem durch diese Leisten bestimmten Abstand, in Umfangsrichtung der Trommel entlang geführt werden. Die Grösse des Kardierspaltes liegt bei einer Wanderdeckelkarde zwischen 0.10 bis 0.30 mm für Baumwolle oder bis 0.40 mm für Chemiefasern.In a carding machine, the lid area together with the drum forms the main carding zone and has as function the dissolution of the flakes into single fibers, removal of impurities and dust, elimination of very short fibers, the dissolution of nits and the parallelization of the fibers. Depending on the application of a card, hard covers, revolving lids or a mixture of fixed and revolving lids are used. When using a revolving lids or a mixture of hard covers and revolving lids, one speaks of a revolving flat card. Between the sets of covers and the clothing of the drum forms a narrow gap called the carding nip. It results in the use of revolving lids by the revolving lids, guided by arcuate strips - so-called flexible arch, Regulierbogen, Flexbogen or Gleitbogen - are guided along a predetermined distance by these strips in the circumferential direction of the drum. The size of the carding nip lies with a revolving flat card between 0.10 to 0.30 mm for cotton or up to 0.40 mm for man-made fibers.
Es ist bekannt, dass die Flexibelbogen radial verstellbar ausgeführt sein müssen, um einen über den gesamten Verlauf der Flexibelbogen gleichbleibenden Kardierspalt gewährleisten zu können. Die radiale Verstellbarkeit ist notwendig aus verschiedenen Gründen:
- a) Zur Neueinstellung des Kardierspaltes bei der Herstellung der Karde oder nach einem Ersatz der Trommelgarnitur. Dabei ist eine individuelle Verstellung von einzelnen Lagerstellen notwendig, um eine konzentrische Einstellung der Flexibelbogen gegenüber der Trommeloberfläche zu ermöglichen
- b) Zur Nachstellung des Kardierspaltes bei Abnutzungserscheinungen der Garnituren, wobei hier eine gleichmässige Verstellung aller Lagerstellen erwünscht ist
- c) Zur Nachstellung des Kardierspaltes nach einem Schleifen der Garnituren
- d) Zur Korrektur des Kardierspaltes aufgrund der thermischen Ausdehnung der Trommel
- e) Zur Einstellung des Kardierspaltes bei unterschiedlichen Trommel- oder DeckelGarniturhöhen abhängig von der im Einsatz stehenden Garnitur.
- a) To readjust the carding gap during the production of the card or after a replacement of the drum set. In this case, an individual adjustment of individual bearings is necessary to allow a concentric adjustment of the flexible sheet opposite the drum surface
- b) For adjustment of the carding gap in case of wear of the trimmings, in which case a uniform adjustment of all bearings is desired
- c) To re-adjust the carding gap after sanding the sets
- d) To correct the carding gap due to the thermal expansion of the drum
- e) For setting the carding gap with different drum or lid set heights depending on the set in use.
Bei einer bekannten Vorrichtung ist der Flexibelbogen mit Einstellschrauben am Maschinengestell befestigt. Die Einstellschrauben ermöglichen eine konzentrische Einstellung der Oberfläche des Flexibelbogens, sodass die Wanderdeckel entlang der Trommeloberfläche mit gleichbleibendem Abstand geführt werden können. Die Einstellgenauigkeit ist dabei abhängig von der Ausführung der Einstellschrauben.In a known device, the flexible bend is secured with adjusting screws on the machine frame. The adjustment screws allow for a concentric adjustment of the flexible arch surface so that the traveling lids can be kept at a constant distance along the drum surface. The setting accuracy depends on the design of the adjusting screws.
In der
Nachteilig an der Vorrichtung ist, dass der gesamte Flexibelbogen bewegt werden muss um den Kardierspalt einzustellen. Insbesondere ist die Feineinstellung durch die Bewegung des Flexibelbogens vorgesehen, was mit einem erheblichen Kraftaufwand verbunden ist und dadurch nur Ruckweise durchgeführt werden kann.In the
A disadvantage of the device is that the entire flexible sheet must be moved to adjust the carding gap. In particular, the fine adjustment is provided by the movement of the flexible bend, which is associated with a considerable expenditure of force and thus only jerking can be performed.
In der
Nachteilig an der offenbarten Ausführung der Lagerung ist jedoch die dazu notwendige aufwändige Konstruktion für die Bewegung des Bolzens über eine vom Bolzen beabstandete Einstellvorrichtung welche mit dem Bolzen über einen Hebel in Verbindung steht. Für eine gleichzeitige Verschiebung aller Auflagepunkte des Flexibelbogens ist ein zusätzliches Verschiebemittel notwendig, was die Konstruktion der Einstellvorrichtung weiter kompliziert.In the
A disadvantage of the disclosed embodiment of the bearing, however, the necessary complex construction for the movement of the bolt via a spaced-apart from the adjusting device which with the bolt via a lever in connection stands. For a simultaneous displacement of all support points of the flexible sheet an additional displacement means is necessary, which further complicates the construction of the adjustment.
Der Erfindung der vorliegenden Anmeldung liegt die Aufgabe zugrunde, eine Lagerung eines Flexibelbogens zu schaffen, welche eine Verstellung des Kardierspaltes an einer einzelnen Lagerstelle, wie auch eine Verstellung des Kardierspaltes an allen Lagerstellen des Flexibelbogens gemeinsam ermöglicht, wobei beide Arten der Verstellung dasselbe Verstellelement nutzen sollen und wobei die Verstellung einer einzelnen Lagerstelle ohne die Beeinflussung der gemeinsamen Verstelleinrichtung möglich sein soll.The invention of the present application has for its object to provide a storage of a flexible arch which allows an adjustment of the carding at a single bearing point, as well as an adjustment of the carding at all bearing points of the flexible sheet together, both types of adjustment to use the same adjustment and wherein the adjustment of a single bearing should be possible without affecting the common adjustment.

Der Flexibelbogen ist bei jeder Lagerstelle derart auf dem jeweiligen Lagerbolzen gehalten, dass bei einer Drehbewegung des Lagerbolzens der Flexibelbogen radial zur Trommelachse verschoben wird. Der Lagerbolzen weist eine Lagerbolzenachse, einen Befestigungsabschnitt, einen Bewegungsabschnitt und eine Auflagefläche für die Auflage des Flexibelbogens auf, dabei ist die Auflagefläche durch eine um die Lagerbolzenachse spiralförmig angeordnete Oberfläche gebildet.To solve the problem, a storage of a flexible sheet is proposed in a revolving flat card with a drum and a drum axis, wherein the bearing comprises at least three bearings, each with a bearing pin and an adjusting lever. The flexible sheet is held at each bearing point on the respective bearing pin, that during a rotational movement of the bearing pin of the flexible sheet is moved radially to the drum axis. The bearing pin has a bearing pin axis, a mounting portion, a movement portion and a support surface for the support of the flexible sheet, while the support surface is formed by a spiral around the bearing pin axis arranged surface.
Für die Abstützung eines Flexibelbogens sind mehrere Abstützpunkte, soggenannte Lagerstellen vorgesehen. Die Anzahl der Lagerstellen ist abhängig von der Ausführung des Flexibelbogens, insbesondere von seiner Länge. Für eine stabile Lagerung sind zumindest drei Lagerstellen notwendig. Die Lagerstellen können in Bezug auf den Flexibelbogen symmetrisch oder asymmetrisch angeordnet sein. Wird der Flexibelbogen jedoch mehrteilig ausgeführt oder führt er über einen grösseren Umfang der Trommel hinweg sind mehr als drei Lagerstellen, beispielsweise fünf oder sieben Lagerstellen notwendig. Dabei erfolgt die Lagerung des Flexibelbogens derart, dass die darauf gleitenden Wanderdeckel in der gewünschten Art der Trommeloberfläche entlang geführt werden.For the support of a flexible arch several support points, so-called bearings are provided. The number of bearings depends on the design of the flexible sheet, in particular its length. For stable storage at least three bearings are necessary. The bearings may be arranged symmetrically or asymmetrically with respect to the flexible arch. However, if the flexible sheet is executed in several parts or leads over a larger circumference of the drum, more than three bearing points, for example five or seven bearing points, are necessary. The storage of the flexible sheet is done so that the sliding on it Travel lids are guided in the desired type of drum surface along.
Der Flexibelbogen wird an jeder Lagerstelle von einem Bolzen gehalten. Der Bolzen selbst ist im Maschinengestell der Wanderdeckelkarde drehbar befestigt, dazu weist der Bolzen einen Befestigungsabschnitt auf. Vorteilhafterweise ist der Befestigungsabschnitt des Bolzens derart angelegt, dass sich auf der einen Seite des Befestigungsabschnittes der Bewegungsabschnitt und auf der anderen Seite des Befestigungsabschnittes die Auflagefläche für den Flexibelbogen anschliesst. Damit ist der Befestigungsabschnitt in Richtung der Lagerbolzenachse zwischen dem Bewegungsabschnitt und der Auflagefläche angeordnet.
In einer bevorzugten Ausführungsform ist der Befestigungsabschnitt durch die innerhalb des Befestigungsabschnittes angeordnete Auflagefläche zweigeteilt. Der Lagerbolzen wird dadurch an zwei Stellen im Maschinengestell gehalten, wobei zwischen diesen beiden Stellen die Auflagefläche für den Flexibelbogen angeordnet ist. Dies hat den Vorteil, dass die Lagerstellen des Lagerbolzens nur durch Kräfte in einer Richtung beansprucht wird und keine Drehmomente auftreten. Bei einer einseitigen Lagerung wirken auf den Lagerbolzen zusätzlich Biegekräfte, was durch einen zweigeteilten Befestigungsabschnitt vermieden werden kann.The flexible bend is held by a bolt at each bearing point. The bolt itself is rotatably mounted in the machine frame of Wanderdeckelkarde, this, the bolt on a mounting portion. Advantageously, the attachment portion of the bolt is designed such that adjoins the movement portion on one side of the attachment portion and on the other side of the attachment portion, the support surface for the flexible bend. Thus, the attachment portion is arranged in the direction of the bearing pin axis between the movement portion and the support surface.
In a preferred embodiment, the attachment portion is bisected by the support surface disposed within the attachment portion. The bearing pin is thereby held in two places in the machine frame, wherein between these two points the support surface for the flexible sheet is arranged. This has the advantage that the bearing points of the bearing pin is stressed only by forces in one direction and no torques occur. In a one-sided storage act on the bearing bolt in addition bending forces, which can be avoided by a two-part mounting portion.
Die Auflagefläche ist spiralförmig um die Lagerbolzenachse angelegt. Dadurch verändert sich, bei einer Drehung des Bolzens um einen bestimmten Winkel, der radiale Abstand der Auflagefläche um einen bestimmten Betrag, welcher abhängig von der Spiralform der Auflagefläche ist. Die nutzbare Auflagefläche erstreckt sich bedingt durch die spiralförmige Ausführung nicht über den gesamten Umfang des Lagerbolzens. Für die Verstellung des Kardierspaltes ist es ausreichend, wenn der Flexibelbogen in seinem Abstand von der Trommelachse in einem Bereich von 2 bis 10 mm verändert werden kann. Diese Änderung des radialen Abstandes des Flexibelbogens von der Trommelachse entspricht der notwendigen Änderung des Abstandes der Auflagefläche von der Lagerbolzenachse. Durch die Spiralform ändert sich damit der Abstand der Auflagefläche von der Lagerbolzenachse ebenfalls um 2 bis 10 mm. Die Spiralform ist dabei beispielsweise derart angelegt, dass sich die Änderung des Abstandes während zumindest des halben Umfangs des Lagerbolzens ergibt. Der radiale Abstand der Auflagefläche von der Lagerbolzenachse verändert sich somit beispielsweise um einen Betrag von 2 bis 10 mm bei einer Drehung des Lagerbolzens um 180°. Bevorzugterweise ist eine Änderung des Abstandes von 4 bis 8 mm anzustreben, als besonders vorteilhaft hat sich eine Abstandsänderung von 6 mm gezeigt.The bearing surface is spirally applied around the bearing pin axis. As a result, with a rotation of the bolt by a certain angle, the radial distance of the support surface changes by a certain amount, which is dependent on the spiral shape of the support surface. The usable bearing surface does not extend over the entire circumference of the bearing pin due to the helical design. For the adjustment of the carding gap, it is sufficient if the flexible sheet can be changed in its distance from the drum axis in a range of 2 to 10 mm. This change in the radial distance of the flexible sheet from the drum axis corresponds to the necessary change in the distance of the support surface from the bearing pin axis. As a result of the spiral shape, the distance of the bearing surface from the bearing pin axis likewise changes by 2 to 10 mm. The spiral shape is, for example, created such that the change in the distance during at least half the circumference of the bearing pin results. The radial distance of the bearing surface of the bearing pin axis thus changes, for example, by an amount of 2 to 10 mm with a rotation of the bearing pin by 180 °. Preferably, a change in the distance of 4 to 8 mm is to be striven for, as has shown a particularly advantageous change in the distance of 6 mm.
Um eine einfache Montage zu ermöglichen ist vorteilhafterweise darauf zu achten, dass die Auflagefläche einen grössten radialen Abstand von der Lagerbolzenachse aufweist, welcher nicht grösser als ein halber Durchmesser des Lagerbolzens an dessen Befestigungsabschnitt ist.In order to enable a simple assembly is advantageously to ensure that the bearing surface has a greatest radial distance from the bearing pin axis, which is not greater than half the diameter of the bearing pin at its attachment portion.
In einer bevorzugten Ausführung ist die Spiralform der Auflagefläche eine archimedische Spirale. Dadurch ist eine Abnahme oder eine Zunahme des Abstandes der Auflagefläche von der Lagerbolzenachse bei einer Drehung des Lagerbolzens linear zum Verdrehwinkel. Eine archimedische Spirale weist eine kontinuierliche Steigung auf. Dies hat den Vorteil, dass die Drehung des Lagerbolzens um einen bestimmten Winkel immer die gleiche Änderung des radialen Abstandes der Auflagefläche bewirkt, unabhängig von der Stellung des Lagerbolzens. Der radiale Abstand (B) der Auflagefläche von der Lagerbolzenachse ergibt sich damit zu B = k x (α+β), wobei k eine Konstante, α den Drehwinkel des Lagerbolzens und β den Winkel zwischen Auflagepunkt und Bewegungslinie des Flexibelbogens darstellt. Besteht die Auflage des Flexibelbogens auf der Auflagefläche aus einer linienförmigen Auflage, wird der Winkel β zwischen Auflagepunkt und Bewegungslinie des Flexibelbogens zu Null.In a preferred embodiment, the spiral shape of the support surface is an Archimedean spiral. Thereby, a decrease or an increase of the distance of the bearing surface from the bearing pin axis with a rotation of the bearing pin is linear to the angle of rotation. An Archimedean spiral has a continuous slope. This has the advantage that the rotation of the bearing pin by a certain angle always causes the same change in the radial distance of the support surface, regardless of the position of the bearing pin. The radial distance (B) of the bearing surface of the bearing pin axis thus results in B = k x (α + β), where k is a constant, α is the rotation angle of the bearing pin and β represents the angle between support point and line of movement of the flexible bend. If the support of the flexible arch on the support surface consists of a linear support, the angle β between support point and movement line of the flexible bend becomes zero.
Bedingt dadurch, dass der Flexibelbogen auf einer der Auflagefläche des Lagerbolzens zugewandten Seite jedoch eine Stützfläche aufweist, welche als eine Ebene ausgebildet ist, liegt der Flexibelbogen tangential auf der spiralförmigen Auflagefläche des Lagerbolzens auf. Die Bewegungslinie entlang derer durch Drehung des Lagerbolzens die Verschiebung des Flexibelbogens erfolgt ist daher nicht identisch mit der Senkrechten auf die Tangente auf welcher der Flexibelbogen aufliegt. Die Senkrechte auf die Tangente des Auflagepunktes des Flexibelbogens steht unter einem bestimmten Winkel zur Verschiebelinie entlang derer der Flexibelbogen durch die Drehung des Lagerbolzens verschoben wird. Um diesem Umstand Rechnung zu tragen ist in einer besonders bevorzugten Ausführungsform die Spiralform der Auflagefläche des Lagerbolzens derart vorzusehen, dass, trotz der Differenz zwischen dem Auflagepunkt des Flexibelbogens auf den Lagerbolzen und der Bewegungslinie, eine lineare Abhängigkeit zwischen dem Drehwinkel des Lagerbolzens und dem Abstand (A) zwischen der Lagerbolzenachse und dem Flexibelbogen in der Bewegungsrichtung des Flexibelbogens besteht. Der Abstand (A) des Auflagepunktes des Flexibelbogens auf der Auflagefläche des Lagerbolzens parallel zur Bewegungslinie des Flexibelbogens ergibt somit zu A = k x α, wobei k eine Konstante und α den Drehwinkel des Lagerbolzens darstellt.Due to the fact that the flexible sheet on a bearing surface of the bearing pin facing side, however, has a support surface which is formed as a plane, the flexible sheet is located tangentially on the spiral bearing surface of the bearing pin. The line of movement along which the rotation of the bearing pin, the displacement of the flexible sheet is therefore not identical to the perpendicular to the tangent on which the flexible sheet rests. The perpendicular to the tangent of the support point of the flexible bend is at a certain angle to the displacement line along which the flexible bend by the rotation of the bearing pin is moved. In order to take this fact into account, in a particularly preferred embodiment, the spiral shape of the support surface of the bearing pin to provide such that, despite the difference between the support point of the flexible sheet on the bearing pin and the line of movement, a linear dependence between the rotation angle of the bearing pin and the distance ( A) exists between the bearing pin axis and the flexible bend in the direction of movement of the flexible bend. The distance (A) of the support point of the flexible sheet on the support surface of the bearing pin parallel to the line of movement of the flexible bend thus results in A = kx α, where k is a constant and α represents the rotation angle of the bearing pin.
In einer bevorzugten Ausführungsform ist der Verstellhebel auf dem Bewegungsabschnitt des Lagerbolzens gehalten. Dabei ist der Verstellhebel mit einer lösbaren Arretierung drehfest auf dem Lagerbolzen gehalten. Die Arretierung umfasst eine Feststellschraube und einen zweiteiligen Klemmbolzen. Durch ein Zusammenziehen des Klemmbolzens mit der Feststellschraube ist der Lagerbolzen im Verstellhebel über den Klemmbolzen kraftschlüssig gehalten. Der Klemmbolzen ist in seiner Form entlang seiner Längsachse zumindest einseitig der Form des Lagerbolzens angeglichen. Werden nun die beiden Hälften des Klemmbolzens zusammengezogen, bewirkt dies ein Verspannen des Klemmbolzens gegen den Lagerbolzen. Ebenfalls ist es denkbar anstelle eines Klemmbolzens einen Teil des Verstellhebels elastisch auszuführen. Mit einer Feststellschraube kann dieser elastische Teil des Verstellhebels anschliessend an den Lagerbolzen gepresst werden und eine Fixierung des Verstellhebels auf dem Lagerbolzen bewirken.In a preferred embodiment, the adjusting lever is held on the moving portion of the bearing pin. The adjusting lever is rotatably held on the bearing pin with a releasable locking. The lock comprises a locking screw and a two-piece clamping bolt. By contraction of the clamping bolt with the locking screw of the bearing pin is held in the adjusting lever on the clamping bolt frictionally. The clamping bolt is aligned in its shape along its longitudinal axis at least on one side of the shape of the bearing pin. Now, if the two halves of the clamping bolt pulled together, this causes a distortion of the clamping bolt against the bearing pin. It is also conceivable to execute a part of the adjusting lever elastically instead of a clamping bolt. With a locking screw of this elastic part of the adjusting lever can then be pressed against the bearing pin and cause a fixation of the adjusting lever on the bearing pin.
Um eine Grundeinstellung oder eine Veränderung jeder einzelnen Lagerstelle des Flexibelbogens vornehmen zu können, ist eine Vorrichtung vorgesehen, welche eine Drehung des Lagerbolzens unabhängig vom Verstellhebel und unabhängig von den jeweils anderen Lagerstellen ermöglicht. Dazu ist in einer vorteilhaften Ausführung vorgesehen, dass der Bewegungsabschnitt des Lagerbolzens an seinem Umfang zumindest teilweise mit einer Verzahnung versehen ist. Weiter ist im Verstellhebel ein Einstellglied vorgesehen, welche mit der Verzahnung am Umfang des Lagerbolzens eine Untersetzungsstufe (wie z.B. einen Schneckentrieb) bildet. Mit dem Einstellglied kann somit über die Untersetzungsstufe der Lagerbolzen in Drehung versetzt und damit der Flexibelbogen in die gewünschte Grundstellung gebracht werden. Da die Verschiebung des Flexibelbogens in einem linearen Verhältnis zum Drehwinkel des Lagerbolzens steht, und der Drehwinkel des Lagerbolzens über die Untersetzungsstufe mit dem Drehwinkel des Einstellgliedes ebenfalls in einem vorgegeben Verhältnis steht, kann eine genaue und vorhersehbare Verschiebung des Flexibelbogens erfolgen. Zur Drehung des Einstellgliedes kann dieses mit einer zu einem bestimmten Werkzeug passenden Kupplungsstück versehen sein, dies kann beispielsweise ein Sechskantkopf, ein Innensechskant oder eine andere Art einer bekannten drehfesten Kupplung bei der Verwendung von Handwerkzeugen sein. Nach der Vornahme einer individuellen Grundeinstellung einer Lagerstelle wird der Verstellhebel wiederum über die Arretierung drehfest mit dem Verstellhebel verbunden.In order to make a basic setting or a change of each bearing of the flexible sheet, a device is provided which allows rotation of the bearing pin independent of the adjusting lever and independently of the other respective bearing points. For this purpose, it is provided in an advantageous embodiment that the movement portion of the bearing pin is provided at least partially with a toothing on its circumference. Next, an adjusting member is provided in the adjusting lever, which forms a reduction stage (such as a worm drive) with the toothing on the circumference of the bearing pin. With the adjustment can thus over the reduction stage of the bearing pin set in rotation and thus the flexible sheet are brought into the desired basic position. Since the displacement of the flexible bend is in a linear relationship to the rotational angle of the bearing pin, and the rotation angle of the bearing pin on the reduction stage with the rotation angle of the adjusting member is also in a predetermined ratio, a precise and predictable displacement of the flexible sheet can take place. For rotation of the adjusting member, this may be provided with a suitable coupling tool for a particular tool, this may for example be a hexagonal head, a hexagon socket or another type of known rotationally fixed coupling when using hand tools. After making an individual default setting of a bearing, the adjusting lever is in turn rotatably connected via the lock with the adjusting lever.
Dadurch dass die Auflagefläche des Lagerbolzens für eine nur vom Drehwinkel des Lagerbolzens abhängige Verschiebung des Flexibelbogens bewirkt, spielt es keine Rolle in welcher momentan individuellen Stellung sich die spiralförmige Auflagefläche des Lagerbolzens einer jeden Lagerstelle befindet. Ein Weiterdrehen des Lagerbolzens führt immer zu einer linear zum Drehwinkel wirkenden Verschiebung des Flexibelbogens.The fact that the bearing surface of the bearing pin causes only dependent on the rotation angle of the bearing pin displacement of the flexible sheet, it does not matter in what moment individual position is the spiral bearing surface of the bearing pin of each bearing. Further rotation of the bearing pin always leads to a linearly acting to the rotation angle displacement of the flexible bend.
Die Verstellhebel der einzelnen Lagerstellen sind mit einem gemeinsamen Schieber verbunden. Diese Verbindung bewirkt, dass die Verstellhebel und über die Arretierung auch die Lagerbolzen drehfest gehalten sind. Die Halterung der Verstellhebel im Schieber ist über eine im Schieber angeordnete radial ausgerichtete Führungsnut ausgeführt. Am Verstellhebel ist dazu ein Führungsstift vorgesehen, welcher in die Führungsnut greift. Wird der Schieber nun tangential zur Trommelachse bewegt, überträgt sich diese Bewegung über die Führungsstifte auf die Verstellhebel und führt zu einer Verdrehung der Verstellhebel um die Lagerbolzenachse. Durch die Arretierung der Verstellhebel auf dem Lagerbolzen wird die Drehung der Verstellhebel auf die Lagerbolzen übertragen. In der Folge wird durch die Drehung der Lagerbolzen der Flexibelbogen in allen Lagerstellen gleichzeitig und bedingt durch die spiralförmige Auflagefläche der Lagerbolzen in allen Lagerstellen um denselben Betrag radial verschoben. Dabei ist die Verschiebung unabhängig von der momentanen individuellen Einstellung der einzelnen Lagerstellen.The adjusting levers of the individual bearings are connected to a common slider. This connection causes the adjustment lever and the lock and the bearing pin are held against rotation. The holder of the adjusting lever in the slide is designed via a arranged in the slide radially aligned guide. On the adjusting lever a guide pin is provided, which engages in the guide groove. If the slider is now moved tangentially to the drum axis, this movement is transmitted via the guide pins on the adjusting lever and leads to a rotation of the adjusting lever about the bearing pin axis. By locking the adjusting lever on the bearing pin, the rotation of the adjusting lever is transmitted to the bearing pin. As a result, by the rotation of the bearing pin of the flexible bend in all bearings simultaneously and due to the spiral bearing surface of the bearing pin in all bearings shifted by the same amount radially. The shift is independent of the current individual setting of the individual bearings.
In einer weiterführenden Ausführung ist der Schieber mit einem Antrieb versehen. Dies ermöglicht eine automatische Verstellung des Flexibelbogens durch eine zentrale Steuerung. Dabei steht die tangentiale Bewegung des Schiebers in einem festen Verhältnis zur Verschiebung des Flexibelbogens. Über den Verstellhebel und die spiralförmige Auflagefläche des Lagerbolzens wird die Bewegung des Schiebers übersetzt, wodurch eine große Bewegung des Schiebers zu einer kleinen Verschiebung des Flexibelbogens führt. Dies ermöglicht eine hohe Genauigkeit in der Verstellung des Flexibelbogens in Schritten von weniger als 0.01 mm.In a further embodiment, the slide is provided with a drive. This allows automatic adjustment of the flexible bend by a central control. The tangential movement of the slider is in a fixed relationship to the displacement of the flexible bend. About the lever and the spiral bearing surface of the bearing pin, the movement of the slider is translated, whereby a large movement of the slider leads to a small displacement of the flexible bend. This allows a high accuracy in the adjustment of the flexible sheet in steps of less than 0.01 mm.
Wird der Antrieb des Schiebers mit einer Steuerung verbunden, welche ihrerseits mit einer bekannten Messvorrichtung zur Bestimmung des Kardierspaltes verbunden ist, kann mit Hilfe des Schiebers eine Deckelaktorik betrieben werden. Eine Deckelaktorik dient zur automatischen Nachstellung des Kardierspaltes zwischen den Wanderdeckeln und der Trommel einer Karde. Werden die Garnituren der Trommel oder die Garnituren der Wanderdeckel beispielsweise nachgeschliffen, wird diese Veränderung des Kardierspaltes durch die Messvorrichtung von der Steuerung festgestellt und selbsttätig über den Schieber ausgeglichen.If the drive of the slide is connected to a controller, which in turn is connected to a known measuring device for determining the carding gap, a cover actuator can be operated with the aid of the slide. A lid actuator is used for automatic adjustment of the carding gap between the revolving lids and the drum of a card. If the trimmings of the drum or the sets of the revolving cover are reground, for example, this change in the carding gap is detected by the measuring device of the controller and compensated automatically via the slide.

Bei einer tangentialen Bewegung 36 des Schiebers 35 werden alle Verstellhebel 26 über deren Führungsstifte 34 um die Lagerbolzenachsen 25 verdreht.
