Definitions
- the present invention relates to a flexible arch for 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. Since the covers are added by dirt and fibers, it is necessary to clean them. Therefore, the revolving lid has been developed, wherein the lid are held together by means of a chain or a belt and combined to form an endless, revolving band. One part is in direct use opposite the drum set. The remaining part is transported via deflection rollers in the supine position and can be cleaned and possibly ground.
- the carding nip Between the sets of covers and drum forms a narrow gap called the carding nip.

- the oldest type is a three-point regulation, as described in Johannsen, Handbuch der Baumwollspinnerei (Volume II, 1963, page 50ff ).
- the flexible sheet is supported at three points by support charges. Adjusting the drum rotation axis to or away from it can change the radius of the flexible-sheet top edge.
- the arc has slots at these support points through which the adjustment means pass.
- a major problem is that between the set points "hills” and / or “valleys” arise, which are reflected directly in a non-uniform carding nip. These deformations can locally cause radial deviations of a few hundredths of a millimeter and are therefore large compared with the typical size of a carding nip mentioned above enough to have a noticeable effect on the carding behavior.

Description
Die vorliegende Erfindung bezieht sich auf einen Flexibelbogen für eine Wanderdeckelkarde.The present invention relates to a flexible arch for a revolving flat card.
Der Deckelbereich bildet 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. Da die Deckel durch Schmutz und Fasern zugesetzt werden, ist es notwendig, diese zu reinigen. Daher wurde der Wanderdeckel entwickelt, wobei die Deckel mittels einer Kette oder einem Riemen zusammen gehalten und zu einem endlosen, umlaufenden Band zusammengefasst werden. Ein Teil steht in direktem Einsatz gegenüber der Trommelgarnitur. Der restliche Teil wird via Umlenkrollen in Rückenlage weitertransportiert und kann gereinigt und eventuell geschliffen werden.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. Since the covers are added by dirt and fibers, it is necessary to clean them. Therefore, the revolving lid has been developed, wherein the lid are held together by means of a chain or a belt and combined to form an endless, revolving band. One part is in direct use opposite the drum set. The remaining part is transported via deflection rollers in the supine position and can be cleaned and possibly ground.
Zwischen den Garnituren von Deckeln und Trommel formt sich ein enger Spalt, der Kardierspalt genannt wird. Er ergibt sich, indem die Wanderdeckel, geführt durch bogenförmige Leisten - genannt Flexibelbögen, Regulierbögen, Flex-Bögen, Flexibelbögen oder Gleitbögen -, in einem bestimmten, nicht zwingendermassen konstanten Kardierabstand, in Umfangsrichtung der Trommel entlang geführt werden. Die Grösse des Kardierspalts liegt bei einer Wanderdeckelkarde zwischen 0.10...0.30 mm für Baumwolle oder bis 0.40 mm für chemische Fasern. Daher ist die präzise Einstellbarkeit des Flexibelbogens von zentraler Bedeutung.Between the sets of covers and drum forms a narrow gap called the carding nip. It results from the fact that the revolving lids, guided by arcuate strips - called flexible bows, Regulierbögen, flex bends, flexible bows or bends - are guided in a certain, not necessarily constant carding, in the circumferential direction of the drum along. The size of the carding nip for a revolving flat card is between 0.10 ... 0.30 mm for cotton or up to 0.40 mm for chemical fibers. Therefore, the precise adjustability of the flexible sheet is of central importance.
Die Deckel gleiten in Arbeitsposition auf den Flexibelbögen, wenn die Garnituren von Trommel und Deckeln gegen einander angeordnet sind. Diese Flexibelbögen stehen etwa konzentrisch zur Trommel-Rotationsachse, an jeder Seite der Trommel einer. Sie sind an den Seitenstücken oder Trommelschildern der Karde befestigt, und zwar so, dass sie leicht und sicher nachgestellt werden können. Da sich mit dem Abschleifen und der Abnutzung der Garnituren der Kardierspalt laufend ändert, müssen die Bögen flexibel ausgebildet sein, um ein Nachstellen und somit eine Korrektur des Kardierspaltes auf das Sollmass, ermöglichen zu können. Zu diesem Zweck sind die Flexibelbögen meist aus einer Speziallegierung gegossen, die elastische Eigenschaften besitzt. Somit können die Flexibelbögen mit verhältnismässig geringem Kraftaufwand und kleiner Spannungsbelastung in die notwendige Form gebracht werden.The lids slide into working position on the flexible sheets when the drum and lid assemblies are positioned against each other. These flexures are approximately concentric with the drum axis of rotation, one on each side of the drum. They are attached to the side pieces or drum labels of the card, in such a way that they can be easily and safely readjusted. Since the carding nip changes continuously with the grinding and the wear of the sets, the bows must be flexible in order to adjust and thus correct the Kardierspaltes on the target size to enable. For this purpose, the flexible sheets are usually cast from a special alloy that has elastic properties. Thus, the flexible bows can be brought into the required shape with relatively little effort and less stress.
Für die Einstellung der Deckel, respektive des Kardierspalts, sind im Laufe der Zeit verschiedene Deckelregulierungs-Systeme entwickelt worden. Die älteste Bauart ist eine Dreipunkt-Regulierung, wie beschrieben in
Obwohl viele Verbesserungsvorschläge für die Einstellvorrichtungen und Regulierung vorgeschlagen sind, gibt es in der Praxis immer noch Probleme mit ungewünschten Verformungen der Flexibelbögen. Ein Hauptproblem liegt darin, dass zwischen den Einstellpunkten "Hügel" und/oder "Täler" entstehen, die sich direkt in einem nicht gleichmässig verlaufenden Kardierspalt niederschlagen. Diese Verformungen können örtlich radiale Abweichungen von einigen Hundertstel mm bewirken und sind daher, verglichen mit der eingangs erwähnten, typischen Grösse eines Kardierspalts, gross genug, um einen merkbaren Effekt auf das Kardierverhalten zu haben. Was sich wiederum negativ in der Qualität des Bandes, dem Endprodukt der Karde, niederschlägt.For the adjustment of the lid, respectively the carding gap, over time different lid regulation systems have been developed. The oldest type is a three-point regulation, as described in
Although many suggestions for adjustment and adjustment are suggested, in practice, there are still problems with undesirable flexural flexure deformations. A major problem is that between the set points "hills" and / or "valleys" arise, which are reflected directly in a non-uniform carding nip. These deformations can locally cause radial deviations of a few hundredths of a millimeter and are therefore large compared with the typical size of a carding nip mentioned above enough to have a noticeable effect on the carding behavior. What in turn negatively reflected in the quality of the tape, the end product of the card.
Der Erfindung der vorliegenden Anmeldung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs beschriebenen Art zu schaffen, welche die genannten Nachteilen vermeidet und insbesondere mögliche unerwünschte Verformungen der Vorrichtung zwischen den Einstellpunkten verhindert.The invention of the present application has for its object to provide a device of the type described above, which avoids the disadvantages mentioned and in particular prevents possible undesirable deformations of the device between the setpoints.
Diese Aufgabe wird erfindungsgemäss durch eine Vorrichtung mit den Merkmalen des unabhängigen Patentanspruchs 1 gelöst. Insbesondere dadurch, den Flexibelbogen derart zu konstruieren, dass sich bei einer Verstellung der Einstellpunkte die Oberkante des Flexibelbogens bei gleich bleibender Form über den ganzen Kardierbereich gleichmässig anhebt oder absenkt. Beispielsweise soll vermieden werden, dass ein Flexibelbogen mit anfänglich kreisförmiger Oberkante nach der Verstellung elliptisch geformt ist.This object is achieved according to the invention by a device having the features of

Die Deckel gehören zu einem System von Wanderdeckeln (2), dabei werden Deckel mit Hilfe von einem Endlosriemen oder einer Kette via Umlenkrollen (6) mittels eines Antriebs über die Trommeloberfläche fortbewegt, meistens gegen die Drehrichtung der Trommel. Die Unterseite der Deckel ist mit einer Garnitur versehen, zum Beispiel mit einer Sägezahngarnitur oder flexiblen Garnituren in Form von Häkchen. Auch die Trommel hat eine Garnitur, die mit dem Deckel zusammenarbeitet. Ein Wanderdeckelsatz besteht aus rund 80...120 Deckel, wovon nur ein Teil in Arbeitsstellung steht. Die Anzahl Deckel in Arbeitsstellung ist u. a. abhängig vom Durchmesser der Trommel und der Wandeldeckelanordnung. Im Durchschnitt sind es 20...46 Deckel. Zwischen der Trommel- und der Deckel-Garnitur ist ein Spalt, der Kardierspalt genannt wird. Weiter hat der Flexibelbogen Mittel (13) zum Einstellen der Bogen, so angeordnet, damit eine genaue Einstellung des Kardierspalts vorgenommen werden kann. Dieser Kardierspalt wird normalerweise eingestellt mit einem gleich bleibenden Abstand zur Trommel, über fast die ganze Kardierzone. Allerdings kann der Spalt auch öffnend - der Kardierspalt wird grösser - oder schliessend - der Kardierspalt wird kleiner - eingestellt werden. Für die Kontrolle der Einstellung können in der Seite der Bögen Schlitze angebracht sein, wodurch mit Messlehren der Abstand zwischen den Garnituren gemessen werden kann.The lids belong to a system of revolving lids (2), whereby lids are moved by means of an endless belt or a chain via pulleys (6) by means of a drive over the drum surface, usually against the direction of rotation of the drum. The underside of the lid is provided with a set, for example with a Sägezahngarnitur or flexible sets in the form of check mark. The drum also has a set that works with the lid. A revolving lid set consists of around 80 ... 120 lids, of which only a part is in working position. The number of lids in working position is u. a. depending on the diameter of the drum and the convertible lid arrangement. On average, there are 20 ... 46 lids. Between the drum and the lid set is a gap called the carding nip. Further, the flexible sheet means (13) for adjusting the sheet, arranged so that an accurate adjustment of the carding gap can be made. This carding nip is normally set at a constant distance from the drum, over almost the entire carding zone. However, the gap can also be opened - the carding gap is larger - or closing - the carding gap is smaller - to be set. To control the adjustment, slots may be provided in the side of the arches, whereby the distance between the trims can be measured with gauges.
Diese haben dazu spezielle Endstücke.
These have special end pieces for this purpose.
In der Folge wird zur Erläuterung der Flexibelbogen-Form gemäss Erfindung von einer kreisförmigen Flexibelbogen-Oberkante ausgegangen. Dies ist aber keine zwingende Bedingung, wie sich später erweisen wird.In the following, it is assumed to explain the flexible arch form according to the invention of a circular flexible elbow top edge. However, this is not a mandatory condition, as will later prove.
Der Flexibelbogen habe also eine Oberkante mit konstanter Krümmung, die als Gleitfläche für die Deckel diene und kreisförmig-konzentrisch zur Trommel-Rotationsachse angeordnet sei. Dies führt zu einem gleich bleibenden Kardierspalt über die ganze Kardierzone.
Der erfinderische Flexibelbogen ist nun durch einen charakteristischen Profilverlauf h(ϕ) gekennzeichnet, welcher entlang dem Umfang (resp. Oberkante (9)) in Richtung Zentrum (12) ausgebildet ist. Dieser Profilverlauf kann aus dem Flächeträgheitsmoment abgeleitet werden, welches lautet:
wobei I : Flächenträgheitsmoment; I0 : I am mittleren Einstellungspunkt; ϕ: Winkel ausgehend vom mittleren Einstellungspunkt; ϕ 0 : Winkel zwischen mittlerem und äusserem Einstellpunkt.
Die theoretischen Grundlagen zur Herleitung dieser Formel sind unter anderem zu finden in Dubbel, Taschenbuch für den Maschinenbau, 18. Auflage, Abs. 2.4, Biegebeanspruchung (Bending), p. 186ff.The flexible sheet thus has an upper edge with a constant curvature, which serve as a sliding surface for the cover and is arranged circular-concentric to the drum axis of rotation. This leads to a constant carding gap over the entire carding zone.
The inventive flexible sheet is now characterized by a characteristic profile curve h (φ) which is formed along the circumference (or upper edge (9)) in the direction of the center (12). This profile profile can be derived from the area moment of inertia, which is:
where I : area moment of inertia; I 0 : I at the middle setting point; φ: angle from the middle setting point; φ 0 : Angle between middle and outer setpoint.
The theoretical basis for the derivation of this formula can be found, inter alia, in Dubbel, Paperback for Mechanical Engineering, 18th edition, para. 2.4, bending stress (Bending), p. 186ff.
Die erfinderische Geometrie des Flexibelbogens ist daher unabhängig von der Kontur der Oberkante. Die notwendige und hinreichende Bedingung für den Flexibelbogen ist, dass das Flächenträgheitsmoment linear abnimmt über den Umfang, von I = I0 (bei ϕ = 0) zu I = 0 (bei ϕ = ϕ0). The inventive geometry of the flexible bend is therefore independent of the contour of the upper edge. The necessary and sufficient condition for the flexible bend is that the moment of area momentum decreases linearly over the circumference, from I = I 0 (at φ = 0) to I = 0 (at φ = φ 0 ).
Wird das Profil eines Flexibelbogens nach dieser Gesetzmässigkeit gefertigt, ist eine gleichmässige Verformung der Oberkante gegeben. Bezogen auf die eingangs getroffene Annahme, der Flexibelbogen habe eine kreisförmige Oberkante, heisst das: Wenn die Einstellpunkte allesamt um einen bestimmten Betrag zum Kreiszentrum hin oder davon weg verstellt werden, besitzt der Flexibelbogen danach immer noch eine Kreisform, definiert durch einen Radius, der um diesen Betrag kleiner oder grösser ist, als der Ausgangradius.If the profile of a flexible bend is made according to this law, a uniform deformation of the upper edge is given. Based on the assumption made at the beginning, that the flexible bend has a circular upper edge, this means: If the adjustment points are all adjusted by a certain amount towards or away from the circle center, then the flexible bend still has a circular shape, defined by a radius that changes this amount is smaller or larger than the output radius.
Die Profilform des Flexibelbogen, berechnet aus dem gegebenen Flächenträgheitsverlauf, ist insbesondere abhängig vom Querschnitt des Flexibelbogens. Grundsätzlich wird ein rechteckiger Querschnitt eingesetzt, allerdings kann auch ein Querschnitt in Trapezform oder eine abgerundete Variante eingesetzt werden. Es sind ebenso beliebige Querschnitte denkbar, die nicht einmal über den ganzen Flexibelbogen gleich sein müssen. Im Speziellen gilt für einen rechteckigen Querschnitt:
Hierbei ist b : Breite des Querschnitts und h: Höhe des Querschnitts.The profile shape of the flexible sheet, calculated from the given surface inertia curve, is dependent, in particular, on the cross section of the flexible sheet. Basically, a rectangular cross-section is used, however, a cross-section in trapezoidal shape or a rounded variant can be used. There are also any cross-sections conceivable that do not even have to be the same over the entire flexible arch. In particular, for a rectangular cross section:
Where b is the width of the cross section and h is the height of the cross section.
Der Verlauf der Profilhöhe h(ϕ) des Flexibelbogens im Intervall 0<ϕ<ϕ0 kann mittels folgender Formel für rechteckige Querschnitte konstruiert werden:
Die erfinderische Geometrie des Flexibelbogens ist unabhängig von der Auswahl der Materialien oder deren Eigenschaften. Durch die passende Berechnung der Profilform aus dem Flächenträgheitsmoment können auch Löcher - notwendig im Flexibelbogen, wenn man zum Beispiel mit einer Messlehre den eingestellten Kardierspalt kontrollieren will - berücksichtigt werden. Der Flexibelbogen kann auch aus mehreren Teilen bestehen, die gemeinsam wieder einen Baugruppe bilden, z. B. zwei keilförmigen Bogenteile, wie beschrieben in
The inventive geometry of the flexible sheet is independent of the choice of materials or their properties. Due to the appropriate calculation of the profile shape from the area moment of inertia, holes can also be taken into account - necessary in the flexible bend, if, for example, you want to check the set carding gap with a gauge. The flexible sheet may also consist of several parts, which together form an assembly again, z. B. two wedge-shaped arch parts, as described in
