Abstract

Described is a foulard machine with the minimum possible application of liquor. For this purpose, a wiper is held against the circumference of an enlacing roller by means of forces of magnetic repulsion. The wiper has a plurality of recesses or indents next to one another which act to convey the liquor. Any out-of-rounds of the enlacing roller are compensated for by the forces of magnetic repulsion so that the wiper abuts against the circumference of the roller uniformly over its entire length.

Description

Die Erfindung betrifft einen Foulard mit einer Umschlingungswalze für eine zu behandelnde textile Warenbahn und einem Trog zur Aufnahme einer Flotte, die von der sich drehenden Umschlingungswalze auf den Trog aufgenommen wird und über eine am Umfang der Umschlingungswalze anliegende Rakel, die die überschüssige Flotte abstreift, auf die Warenbahn übertragen wird, wobei die Rakel an ihrer an der Umschlingungswalze anliegenden Berührungsfläche eine Vielzahl von nebeneinanderliegenden Aussparungen hat und mittels Magnetkraft über ihre Länge zur Anlage am Umfang der Umschlingungswalze gehalten ist.The invention relates to a foulard with a wrapping roller for a textile material web to be treated and a trough for receiving a liquor which is taken up by the rotating wrapping roller on the trough and via a doctor blade which abuts the circumference of the wrapping roller and wipes off the excess liquor the material web is transferred, the doctor blade having a large number of recesses lying next to one another on its contact surface abutting the wrap-around roller and being held by means of magnetic force over its length for abutment against the circumference of the wrap-around roller.

Einen derartigen Foulard beschreibt die EP-A Nr. 0047484. Gegenüber anderen, vorher verwendeten Foulards zeichnet sich dieser bekannte Foulard durch einen möglichst geringen Flottenauftrag aus. Dies wird dort dadurch bewirkt, dass zum einen die Rakel über ihre Länge eine Vielzahl von nebeneinanderliegenden Aussparungen hat, die als Durchlässe für die Flotte wirken. Die Aussparungen haben eine Tiefe von einigen zehntel Millimetern. In den Bereichen zwischen diesen Durchlässen liegt die Rakel über ihre gesamte Länge möglichst gleichförmig am Umfang der Umschlingungswalze an. Dies wird dort dadurch bewirkt, dass in der Umschlingungswalze ein Magnetstab angeordnet ist, und zwar direkt der Rakel gegenüber. Dadurch wird also die Rakel über ihre Länge an den Magnetstab und damit an den Umfang der Umschlingungswalze gezogen.Such a foulard is described in EP-A No. 0047484. Compared to other previously used foulards, this known foulard is characterized by the lowest possible liquor application. This is achieved there by the fact that, on the one hand, the doctor blade has a large number of adjacent recesses over its length, which act as passages for the fleet. The recesses have a depth of a few tenths of a millimeter. In the areas between these passages, the doctor blade lies as uniformly as possible over the entire length of the circumferential roller. This is achieved there by the fact that a magnetic rod is arranged in the wrapping roller, directly opposite the doctor blade. As a result, the doctor blade is drawn along its length to the magnetic rod and thus to the circumference of the wrapping roller.

Die Praxis hat aber gezeigt, dass dieser vorbekannte Foulard nicht ganz zufriedenstellend arbeitet. Weil nämlich mit sehr geringen Flottenauftragsmengen gearbeitet werden soll, ist es absolut erforderlich, dass die an der Umschlingungswalze gehaltene Rakel über ihre Länge gleichmässig anliegt, weil sonst, bezogen auf die Warenbreite, ungleichmässig Flotte aufgetragen wird. Dies verlangt eine vollkommen zylindrische Umschlingungswalze mit absolut gleichmässiger Oberfläche.Practice has shown, however, that this previously known foulard does not work quite satisfactorily. Because it is intended to work with very small amounts of liquor, it is absolutely essential that the doctor blade held on the wrapping roller lies evenly over its length, because otherwise, based on the width of the goods, liquor is applied unevenly. This requires a perfectly cylindrical wrapping roller with an absolutely uniform surface.

Im Praxisversuch hat sich nun gezeigt, dass die Umschlingungswalze diese Bedingung nicht ausreichend erfüllen kann, und zwar aufgrund ihrer zu geringen Wandstärke. Allein durch das Eigengewicht der Walze ergibt sich eine Durchbiegung, die die notwendige, gleichmässige Anlage der Rakel am Umfang der Umschlingungswalze stört. Weiterhin kann die Umschlingungswalze leicht mechanisch beschädigt werden, wobei sich dann Druckstellen usw. ergeben, die ebenfalls die Rakel ungleichmässig anliegen lassen.In practical tests it has now been shown that the wrap roller cannot adequately meet this condition, due to its wall thickness being too small. The weight of the roller alone results in a deflection which interferes with the necessary, uniform application of the doctor blade on the circumference of the wrapping roller. Furthermore, the wrapping roller can easily be mechanically damaged, resulting in pressure points, etc., which can also be applied to the doctor blade unevenly.

Da die Rakel durch magnetische Anziehungskraft in Richtung auf das Innere der Umschlingungswalze angezogen wird, ist es nicht möglich, die Stabilität der Walze, beispielsweise durch eine grössere Wandstärke oder durch eine stärkere Gummiauflage, beliebig zu erhöhen, weil die Magnetkraft quadratisch mit dem Abstand zwischen dem in der Umschlingungswalze befindlichen Magnetstab und der Rakel abnimmt. Aus diesem Grunde kann auch die Stärke einer ggf. vorgesehenen Gummiauflage nicht erhöht werden.Since the squeegee is attracted by magnetic attraction in the direction of the inside of the wrapping roller, it is not possible to increase the stability of the roller, for example by increasing the wall thickness or a thicker rubber pad, because the magnetic force is square with the distance between the in the wrap roller and the doctor blade decreases. For this reason, the thickness of a rubber pad that may be provided cannot be increased.

Der Erfindung liegt daher die Aufgabe zugrunde, einen Foulard der eingangs genannten Art dahingehend weiterzubilden, dass er, unter Verwendung des geschilderten Prinzips der Verwendung einer Rakel mit einer Vielzahl von nebeneinanderliegenden Aussparungen, die mittels Magnetkraft am Umfang der Umschlingungswalze gehalten wird, sich durch einen minimalen Flottenauftrag über die gesamte Breite der betreffenden Warenbahn auszeichnet.The invention is therefore based on the object of developing a foulard of the type mentioned in such a way that, using the principle described, the use of a doctor blade with a plurality of adjacent recesses, which is held by magnetic force on the circumference of the wrapping roller, is minimal Fleet order across the entire width of the relevant web.

Zur Lösung dieser Aufgabe ist die Erfindung dadurch gekennzeichnet, dass die Rakel als Magnetrakel ausgebildet ist und mit Hilfe eines Magnetbalkens, der an ihrer der Umschlingungswalze abgewandten Seite parallel zu ihr vorgesehen ist, mit magnetischer Abstossungskraft an den Umfang der mit einem elastischen Material bespannten Umschlingungswalze gedrückt wird.To achieve this object, the invention is characterized in that the squeegee is designed as a magnetic squeegee and is pressed with the aid of a magnetic bar, which is provided parallel to it on its side facing away from the wrapping roller, with magnetic repulsive force to the circumference of the wrapping roller covered with an elastic material becomes.

Durch diese Massnahmen kann man einen beliebigen, ggf. beliebig kleinen, Abstand zwischen der Magnetrakel und dem Magnetbalken vorsehen, weil der Magnetbalken im Gegensatz zum geschilderten Stand der Technik nicht innerhalb der Umschlingungswalze, sondern ausserhalb dieser Walze vorgesehen ist. Der Mantel der Umschlingungswalze kann daher so stark ausgebildet werden, wie es die jeweiligen Gegebenheiten erfordern, insbesondere um jedwedes Durchbiegen des Mantels der Umschlingungswalze mit Sicherheit zu verhindern. Die ausserdem vorgesehene Bespannung der Umschlingungswalze mit einem elastischen Material, vorzugsweise als Gummiüberzug ausgebildet, egalisiert weitere Unebenheiten. Der Mantel der Umschlingungswalze einschliesslich Überzug kann also so stark gewählt werden, dass die Rakel über ihre gesamte Länge lückenlos mit den Erhebungen zwischen ihren Vertiefungen am Umfang der Umschlingungswalze anliegt, wobei sie über ihre gesamte Länge mittels Magnetkraft an den Umfang der Umschlingungswalze angedrückt wird.These measures make it possible to provide any, possibly arbitrarily small, distance between the magnetic doctor blade and the magnetic bar, because, in contrast to the prior art described, the magnetic bar is not provided inside the wrapping roller, but outside of this roller. The jacket of the wrapping roller can therefore be made as strong as the particular circumstances require, in particular to reliably prevent any bending of the wrapping roller jacket. The provided covering of the wrapping roller with an elastic material, preferably designed as a rubber cover, leveled out further unevenness. The jacket of the wrapping roller, including the coating, can therefore be chosen so strongly that the squeegee rests without gaps over its entire length with the elevations between its depressions on the circumference of the wrapping roller, whereby it is pressed against the circumference of the wrapping roller over its entire length by means of magnetic force.

Die Magnetrakel wird vorzugsweise aus einem drehbar gelagerten Rohr mit gravierter Oberfläche hergestellt, in das Permanentmagnete mit zwischen ihnen befindlichen Polschuhen eingebracht sind, die mittels eines durchgehenden Dorns verspannt sind. Der Dorn hält die Permanentmagnete mit ihren Polschuhen axial fixiert. Im Gegensatz zum geschilderten Stand der Technik, bei dem die Rakel unmagnetisch ist und aus magnetisierbarem Material, d.h. Chrom, besteht, ist die Rakel erfindungsgemäss magnetisch ausgebildet, d.h. es ist eine Magnetrakel.The magnetic squeegee is preferably produced from a rotatably mounted tube with an engraved surface, into which permanent magnets with pole shoes located between them are inserted, which are clamped by means of a continuous mandrel. The mandrel holds the permanent magnets axially fixed with their pole pieces. In contrast to the described prior art, in which the doctor blade is non-magnetic and made of magnetizable material, i.e. Chrome, if the doctor blade is magnetic according to the invention, i.e. it is a magnetic squeegee.

Die Magnetrakel kann aber auch als Mehrkantrohr mit kammartig in eine Seite eingeschnittenen Vertiefungen ausgebildet sein, wobei auch dann in das Rohr nebeneinander Permanentmagnete mit Polschuhen eingebracht sind, die dort in geeigneter Weise fixiert sind.The magnetic squeegee can, however, also be designed as a polygonal tube with comb-shaped recesses in one side, with permanent magnets with pole shoes also being introduced into the tube next to one another and fixed there in a suitable manner.

Der Magnetbalken weist nebeneinander Magnetelemente auf, die gleichnamigen Polen von Magnetelementen der Magnetrakel gegenüberliegen.The magnetic bar has magnetic elements next to each other, which lie opposite poles of the same name of magnetic elements of the magnetic doctor.

Die Magnetelemente des Magnetbalkens können Permanentmagnete oder Elektromagnete sein. Bei der Verwendung von Elektromagneten ergibt sich der Vorteil, dass die Magnetkraft beliebig ein-und ausschaltbar ist, während bei der Verwendung von Permanentmagneten keine gesonderte Stromzuführung notwendig wird.The magnetic elements of the magnetic bar can be permanent magnets or electromagnets. When using electromagnets there is the advantage that the magnetic force can be switched on and off as desired, while no separate power supply is necessary when using permanent magnets.

Der Abstand zwischen der Magnetrakel und dem Magnetbalken soll stufenlos einstellbar sein, um die Andrückkraft entsprechend regulieren zu können.The distance between the magnetic squeegee and the magnetic bar should be infinitely adjustable in order to be able to regulate the pressing force accordingly.

Wichtig ist es, dass die Magnetrakel und der Magnetbalken in axialer Richtung fixiert sind. Nachdem sich nämlich jeweils gleichnamige Pole gegenüberliegen, wollen diese seitlich ausweichen, was verhindert werden muss.It is important that the magnetic squeegee and the magnetic bar are fixed in the axial direction. After the poles of the same name face each other, they want to dodge sideways, which must be prevented.

Zu Reinigungs- und Reparaturzwecken ist es notwendig, den Magnetbalken und auch die Magnetrakel ausbauen zu können. Um hierbei Verletzungen durch die sich dann ggf. anziehenden Magnete zu verhindern, wird es bevorzugt, wenn der Magnetbalken in einer Führung gelagert ist derart, dass der Magnetbalken aus dem Wirkungsbereich der Magnetrakel gebracht werden kann, wobei sich bei dieser Verschiebung gleichzeitig eine Abdeckung aus nichtmagnetischem Material vor den Magnetbalken schiebt. Die Abdeckung soll eine Dicke derart haben, dass die Magnetrakel mit Magnetkraft nicht mehr an den Magnetbalken angezogen werden kann.For cleaning and repair purposes, it is necessary to be able to remove the magnetic bar and the magnetic squeegee. In order to prevent injuries caused by the magnets then possibly attracting, it is preferred if the magnetic bar is mounted in a guide in such a way that the magnetic bar can be moved out of the effective range of the magnetic doctor blade, a cover made of non-magnetic being removed during this displacement Pushes material in front of the magnetic bar. The cover should have a thickness such that the magnetic squeegee can no longer be attracted to the magnetic bar with magnetic force.

Aus demselben Grunde wird es bevorzugt, wenn die Magnetrakel an einem Schwenkbalken befestigt ist, wobei eine Hülse aus nichtmagnetischem Material vorgesehen ist, die auf die Magnetrakel aufschiebbar ist. Hierbei handelt es sich beispielsweise um eine in axialer Richtung geschlitzte Hülse, die bei von der Umschlingungswalze weggeschwenkter Magnetrakel auf diese aufgeschoben werden kann. Die Dicke auch dieser Hülse ist so gewählt, dass die Magnetrakel und der Magnetbalken mit Magnetkraft nicht mehr aneinander haften können.For the same reason, it is preferred if the magnetic squeegee is fastened to a swivel bar, a sleeve made of non-magnetic material being provided which can be pushed onto the magnetic squeegee. This is, for example, a sleeve slotted in the axial direction, which can be pushed onto the magnetic squeegee when the magnetic squeegee is pivoted away from it. The thickness of this sleeve is also selected so that the magnetic squeegee and the magnetic bar can no longer adhere to one another with magnetic force.

Es dient ebenfalls einem möglichst gleichmässigen Flottenauftrag auf die betreffende Warenbahn, wenn in Drehrichtung der Umschlingungswalze hinter einer ersten Leitwalze für die Warenbahn wenigstens eine Aufliegewalze vorgesehen ist, deren Abstand zur Umschlingungswalze einstellbar ist. Diese Massnahme ist durch die erwähnte europäische Offenlegungsschrift an sich bekannt.It also serves for the most uniform possible application of liquor to the web in question if, in the direction of rotation of the wrapping roller, at least one lay-on roller is provided behind a first guide roller for the web, the spacing of which from the wrapping roller is adjustable. This measure is known per se from the aforementioned European publication.

The invention is explained in more detail below on the basis of an exemplary embodiment from which further important features result. Show it:
  • Figure 1 is a schematic front view of the essential components of a novel foulard.

Zunächst sei der grundsätzliche .Aufbau des Foulards anhand von Fig. 1 erläutert. Eine Umschlingungswalze 1 ist vorgesehen, die sich in Richtung des Pfeiles 2 dreht. Der Mantel der Umschlingungswalze hat eine ausreichende Stärke und ist mit einem Gummiüberzug versehen.First of all, the basic structure of the foulard is explained with reference to FIG. 1. A wrap roller 1 is provided which rotates in the direction of arrow 2. The jacket of the wrapping roller is of sufficient strength and is provided with a rubber covering.

Aufeine Warenbahn 3, die in Richtung des Pfeiles 4 durch den Foulard hindurchgeführt wird, soll eine Flotte sehr gleichmässig bei minimalem Flottenverbrauch aufgetragen werden. Die Flotte befindet sich in einem Trog 5.A liquor is to be applied very evenly with minimal liquor consumption to a web of material 3 which is passed through the foulard in the direction of arrow 4. The fleet is in a trough 5.

Hierzu wird die Warenbahn, von einer ersten Leit- oder Vorratswalze 6 kommend, über weitere Leitwalzen 7, 8, 9 und 10, wie in Fig. 1 zeichnerisch dargestellt, geführt. Die Warenbahn liegt also zwischen den Leitwalzen 9 und 10 am Umfang der Umschlingungswalze 1 an. Zwischen diesen beiden Leitwalzen kann eine Aufliegewalze 11 vorgesehen sein, deren Abstand zur Umschlingungswalze 1 vorzugsweise einstellbar ist. Es können auch mehrere derartige, einstellbare Aufliegewalzen vorgesehen sein. Auch die Leitwalzen können einstellbar sein, wie bei Position 7 angedeutet.For this purpose, the material web, coming from a first guide or supply roller 6, is guided over further guide rollers 7, 8, 9 and 10, as shown in the drawing in FIG. 1. The web is therefore between the guide rollers 9 and 10 on the circumference of the wrapping roller 1. A lay-on roller 11 can be provided between these two guide rollers, the distance of which from the wrapping roller 1 is preferably adjustable. Several such adjustable lay-on rollers can also be provided. The guide rollers can also be adjustable, as indicated in position 7.

Die Umschlingungswalze 1 taucht in den Trog 5 ein und nimmt bei ihrer Drehung von dort Flotte auf. Überschüssige Flotte wird bei der Drehung der Umschlingungswalze von einer Magnetrakel 12 abgenommen, die an den Umfang der Umschlingungswalze angedrückt wird. Die Magnetrakel hat nebeneinander eine Vielzahl von Vertiefungen, wie sich aus Fig. 4 und 5 ergibt. Die Vertiefungen sind beispielsweise 0,15 mm tief. Wenn sie nach Fig. 4 nach Art eines Gewindes ausgebildet sind, so hat dies beispielsweise eine Steigung von 0,5 mm.The wrapping roller 1 dips into the trough 5 and, when it rotates, takes up the liquor. Excess liquor is removed during the rotation of the wrapping roller by a magnetic doctor 12, which is pressed against the circumference of the wrapping roller. The magnetic doctor blade has a large number of depressions next to one another, as can be seen from FIGS. 4 and 5. The depressions are 0.15 mm deep, for example. If they are designed in the manner of a thread according to FIG. 4, this has, for example, a pitch of 0.5 mm.

Die Rakel ist magnetisch. Zu diesem Zweck ist sie als Rohr ausgebildet, in das abwechselnd Permanentmagnete 13 und Polschuhe 14 eingeschoben sind (vgl. Fig. 2). Dadurch erhalten die Polschuhe abwechselnd eine unterschiedliche Magnetisierung, die mit N bzw. S gekennzeichnet ist. Fig. 2 lässt ausserdem erkennen, dass den Nordpolen bzw. Südpolen der Magnetrakel Nordpole bzw. Südpole eines Magnetbalkens 15 gegenüberliegen. Zeichnerisch ist dargestellt, dass diese etwas breiter sind als die Nordpole und Südpole der Magnetrakel; sie können aber auch gleich breit oder etwas schmaler sein. Wichtig ist es, dass jeweils einem Südpol ein Südpol und jeweils einem Nordpol ein Nordpol gegenüberliegt.The squeegee is magnetic. For this purpose, it is designed as a tube into which permanent magnets 13 and pole shoes 14 are alternately inserted (cf. FIG. 2). As a result, the pole pieces alternately receive a different magnetization, which is identified by N or S. FIG. 2 also shows that the north poles and south poles of the magnetic squeegee lie opposite north poles and south poles of a magnetic bar 15. It is shown in the drawing that these are somewhat wider than the north and south poles of the magnetic doctor; but they can also be the same width or a little narrower. It is important that a south pole is opposite a south pole and a north pole is opposite a north pole.

Fig. 3 zeigt den konstruktiven Aufbau des Magnetbalkens 15. Dieser besteht aus einer Stange 16, die an einem U-förmigen Bügel 17 gehalten ist. Mittig in der Stange ist eine etwa halbzylindrische Vertiefung vorgesehen, in die nebeneinander ebenfalls halbzylindrische Magnetelemente 18 eingelassen sind.Fig. 3 shows the construction of the magnetic bar 15. This consists of a rod 16 which is held on a U-shaped bracket 17. An approximately semi-cylindrical recess is provided in the center of the rod, into which semi-cylindrical magnetic elements 18 are also embedded next to one another.

Die Magnetelemente sind entweder Permanentmagnete oder Elektromagnete.The magnetic elements are either permanent magnets or electromagnets.

Die Magnetelemente werden durch Haltestangen 19 gehalten, die seitlich auf die Stange 16 aufgeschraubt sind und die jeweils eine Schulter haben, mit der sie die halbschalenförmigen Magnetelemente übergreifen.The magnetic elements are held by holding rods 19 which are laterally on the rod 16 are screwed and each have a shoulder with which they overlap the half-shell-shaped magnetic elements.

Fig. 3 zeigt auch die Magnetrakel 12 und lässt erkennen, dass die Magnetelemente 18 des Magnetbalkens 15 sich halbschalenförmig an den Umfang der Magnetrakel 12 unter einstellbarem Abstand anlegen.3 also shows the magnetic squeegee 12 and reveals that the magnetic elements 18 of the magnetic bar 15 form a half-shell shape on the circumference of the magnetic squeegee 12 at an adjustable distance.

Fig.2 zeigt die Lagerung der Rakel, die bei dieser Ausführungsform nach Fig. 4, d.h. drehbar, gelagert ist. Durch die zeichnerisch dargestellten Stufen wird die Rakel axial fixiert, so dass stets gleichnamige Pole einander gegenüberliegen.Fig. 2 shows the bearing of the doctor blade, which in this embodiment according to Fig. 4, i. is rotatable, mounted. The doctor blade is axially fixed by the steps shown in the drawing, so that poles of the same name always lie opposite one another.

Zu Reinigungs- und Reparaturzwecken kann der Trog 5 nach unten gekippt werden, wie angedeutet. Der Magnetbalken 15 ist hierzu, wie ebenfalls in Fig. 1 gezeigt, um den Weg 20 radial nach aussen verschiebbar. Eine Abdeckung 21 wird hierbei selbsttätig nach unten vorden Magnetbalken geschwenkt und schützt diesen dadurch.The trough 5 can be tilted down for cleaning and repair purposes, as indicated. For this purpose, the magnetic bar 15, as also shown in FIG. 1, can be displaced radially outward by the path 20. A cover 21 is automatically pivoted downwards in front of the magnetic bar and thereby protects it.

Auch die Magnetrakel 12 kann von der Umschlingungswalze abgestellt werden. Zu diesem Zweck wird die Magnetrakel einschliesslich ihres Lagerschutzes um einige Zentimeter ebenfalls radial nach aussen verschoben und kann dann mittels eines Schwenkbalkens 22, der eine geeignete Aufnahme für die Lagerung der Magnetrakel hat, problemlos weggeschwenkt werden, wie zeichnerisch angedeutet. Nach dem Herausschwenken der Magnetrakel wird eine Hülse, ebenfalls aus nichtmagnetischem Material, über die Magnetrakel geschoben, um zu verhindern, dass sie mit Eisenteilen in Berührung kommt.The magnetic squeegee 12 can also be switched off by the wrapping roller. For this purpose, the magnetic squeegee, including its bearing protector, is also displaced radially outward by a few centimeters and can then be pivoted away easily by means of a swivel bar 22, which has a suitable receptacle for mounting the magnetic squeegee, as indicated in the drawing. After swiveling out the magnetic squeegee, a sleeve, also made of non-magnetic material, is pushed over the magnetic squeegee to prevent it from coming into contact with iron parts.

Fig. 2 zeigt ausserdem, dass die Permanentmagnete 13 mit ihren Polschuhen 14 durch einen geeigneten, durch diese Elemente hindurchgehenden Dorn 23 verspannt und lagesicher im Rohr 24 der Magnetrakel 12 gehalten sind.2 also shows that the permanent magnets 13 with their pole pieces 14 are clamped by a suitable mandrel 23 passing through these elements and are held securely in position in the tube 24 of the magnetic doctor blade 12.
