Definitions
- the invention relates to a roller for the coating or the application of ink on tapes, in particular metal tapes in tape coating or tape printing systems, which roller has a rigid base body on which an elastic layer, preferably made of rubber or plastic, is applied.
- rollers have been known for a long time.
- DE-A-35 25 045 has disclosed such a roll of the type mentioned at the outset, in which the rigid body consists of a plastic reinforced with carbon fibers, to which an elastic layer of rubber or plastic is applied.
- These known rollers which are designed to be elastic on their circumference, can ensure a uniformly thick coating application over the entire width of the strip to be coated, even if the base body undergoes a certain deflection despite its rigid construction or if the strip to be coated has its entire cross-section tape is not absolutely uniform. This is achieved in that the elastic layer of the roller can flatten when it is pressed against the strip to be coated.
- These known rollers can also be used as a so-called impression roller opposite a coating roller made of metal or the like, where they are cause the uneven strip to nestle against the coating roller due to its elasticity.
- rollers in coating devices equipped with an elastic surface have the disadvantage that they do not have sufficient resistance to chemicals, e.g. the solvents, acids or bases contained in paints or cleaning agents, as well as very susceptible to mechanical damage, e.g. through sharp band edges.
- the invention is therefore based on the object to design rollers of the type mentioned in such a way that their elastic layer, which enables the flattening of the roller surface, is adequately protected against destruction by solvents, acids and / or alkalis and mechanical influences without their elasticity or resilience significantly affect.
- This object is achieved according to the invention in that the elastic layer of the roller has a thin, flexible metal coating on its outside. This metal coating protects the roller on its surface against chemical or mechanical damage, but is on the other hand so flexible that the roller can nestle with its surface on uneven strip surfaces with more or less flattening of its circumference.
- the roller can be adjusted to the required conditions.
- the elastic layer can consist of a more elastic or less elastic material, for example of a softer or a harder rubber or plastic, depending on the requirements.
- unreinforced plastic so chosen one that is free of reinforcement or stiffening inserts.
- An adaptation of the elasticity of the roller surface to the desired requirements can also be achieved in that there are cavities within the elastic layer, which are connected or can be connected to a pneumatic or hydraulic pressure source and can be pressurized via this source. This enables a continuous adjustment of the elastic layer of the roller to the desired layer hardness.
- the metal jacket preferably has a wall thickness of 0.1 to 1.0 mm and can e.g. made of chrome, nickel or stainless steel.
- the elastic layer can have a thickness of 5 to 70 mm, preferably 15 to 30 mm.
- a roller for printing presses is also known, the essentially rigid base body of which is provided with a coating of ceramic or metal.
- This roller should be subject to the least possible deflection with a light weight and also has a low elasticity on its surface due to the lack of an elastic layer on the roller circumference. It is therefore not in a position to guarantee a coating application that is uniformly thick over the entire range in coil coating systems.
- the invention also relates to a method for applying the metallic coating in the form of a metal jacket to the elastic layer of the roller.
- a method for applying the metallic coating in the form of a metal jacket to the elastic layer of the roller according to the invention, in this process, before the metal jacket is applied first the elastic layer is cooled and the metal jacket is heated. During the subsequent temperature equalization, the metal jacket presses onto the elastic layer and thus receives a coordinated shrink fit on this layer.
- connection between the sheath and elastic layer can also be done by gluing using an elastic adhesive.
- the roller shown in longitudinal section has a base body 1 made of a rigid steel tube, which is seated at its ends via hubs 2 on axle stubs 3.
- an elastic layer 4 made of rubber or plastic is applied, which has a thin, flexible metal coating 5 on its outside.
- This metal coating is formed by a metal jacket which is applied to the elastic layer with a shrink fit. Due to the thin, flexible metal coating 5, the roller described is able to nestle over its entire axial length on uneven surfaces of strips to be coated, in order to thereby ensure a coating application which is uniformly thick over the entire range.
- roller according to the invention Another advantage of the roller according to the invention is that its metal coating can be provided with a grid or other profiling according to the use of the roller, and its surface hardness can be adjusted according to the respective requirements with the aid of thin-layer or thick-layer technology. Coatings, for example with ceramic or titanium nitride, or other surface treatments are also suitable here.
- the roller according to the invention can be used not only in belt systems, but also wherever rollers or rollers with elastic or resilient surfaces are required which are subject to wear or chemical attack.
- the roller according to the invention can be used as an impression roller, squeeze roller, as an immersion roller in belt treatment plants, as a damping roller or as a wear-protected “soft” roller in coil coating or printing processes.
Abstract
Description
Die Erfindung betrifft eine Walze für die Beschichtung oder den Farbauftrag auf Bändern, insbesondere Metallbändern in Bandbeschichtungs- oder Bandbedruckungsanlagen, welche Walze einen biegesteifen Grundkörper hat, auf dem eine elastische Schicht, vorzugsweise aus Gummi oder Kunststoff, aufgebracht ist.The invention relates to a roller for the coating or the application of ink on tapes, in particular metal tapes in tape coating or tape printing systems, which roller has a rigid base body on which an elastic layer, preferably made of rubber or plastic, is applied.
Derartige Walzen sind seit langem bekannt. So ist z.B. durch die DE-A-35 25 045 eine solche Walze der eingangs genannten Gattung bekannt geworden, bei der der biegesteife Grundkörper aus einem mit Kohlefasern verstärkten Kunststoff besteht, auf welchen eine elastische Schicht aus Gummi oder Kunststoff aufgebracht ist. Diese bekannten, an ihrem Umfang elastisch ausgebildeten Walzen können auf dem zu beschichtenden Band über die gesamte Bandbreite einen gleichmäßig dicken Beschichtungsauftrag gewährleisten, und zwar auch dann, wenn der Grundkörper trotz seiner biegesteifen Ausbildung eine gewisse Durchbiegung erfährt oder wenn das zu beschichtende Band über seinen Gesamtquerschnitt nicht absolut gleichmäßige Banddicke hat. Dies wird dadurch erreicht, daß die elastische Schicht der Walze bei ihrem Andruck gegen das zu beschichtende Band eine Abplattung erfahren kann. Diese bekannten Walzen können auch als sogenannte Presseur-Walze einer aus Metall oder dergleichen bestehenden Beschichtungswalze gegenüberliegend eingesetzt werden, wo sie durch ihre Elastizität ein Anschmiegen des unebenen Bandes an die Beschichtungswalze bewirken.Such rollers have been known for a long time. For example, DE-A-35 25 045 has disclosed such a roll of the type mentioned at the outset, in which the rigid body consists of a plastic reinforced with carbon fibers, to which an elastic layer of rubber or plastic is applied. These known rollers, which are designed to be elastic on their circumference, can ensure a uniformly thick coating application over the entire width of the strip to be coated, even if the base body undergoes a certain deflection despite its rigid construction or if the strip to be coated has its entire cross-section tape is not absolutely uniform. This is achieved in that the elastic layer of the roller can flatten when it is pressed against the strip to be coated. These known rollers can also be used as a so-called impression roller opposite a coating roller made of metal or the like, where they are cause the uneven strip to nestle against the coating roller due to its elasticity.
Die bekannten, mit elastischer Oberfläche ausgestatteten Walzen in Beschichtungseinrichtungen haben jedoch den Nachteil, daß sie keine ausreichende Beständigkeit gegenüber Chemikalien, z.B. den in Farben oder Reinigungsmitteln enthaltenen Lösungsmitteln, Säuren oder Laugen haben, sowie sehr anfällig für mechanische Beschädigungen, z.B. durch scharfe Bandkanten sind.However, the known rollers in coating devices equipped with an elastic surface have the disadvantage that they do not have sufficient resistance to chemicals, e.g. the solvents, acids or bases contained in paints or cleaning agents, as well as very susceptible to mechanical damage, e.g. through sharp band edges.
Der Erfindung liegt daher die Aufgabe zugrunde, Walzen der eingangs genannten Gattung so zu gestalten, daß ihre elastische, das Abplatten der Walzenoberfläche ermöglichende Schicht gegen Zerstörung durch Lösungsmittel, Säuren und/oder Laugen sowie mechanische Einflüsse ausreichend geschützt ist, ohne ihre Elastizität bzw. Nachgiebigkeit wesentlich zu beeinträchtigen. Gelöst wird diese Aufgabe erfindungsgemäß dadurch, daß die elastische Schicht der Walze an ihrer Außenseite einen dünnen, biegsamen Metallüberzug hat. Dieser Metallüberzug schützt die Walze an ihrer Oberfläche gegen chemische oder mechanische Beschädigungen, ist jedoch andererseits derart biegsam, daß sich die Walze mit ihrer Oberfläche an unebene Bandoberflächen unter mehr oder weniger starker Abplattung ihres Umfanges anschmiegen kann.The invention is therefore based on the object to design rollers of the type mentioned in such a way that their elastic layer, which enables the flattening of the roller surface, is adequately protected against destruction by solvents, acids and / or alkalis and mechanical influences without their elasticity or resilience significantly affect. This object is achieved according to the invention in that the elastic layer of the roller has a thin, flexible metal coating on its outside. This metal coating protects the roller on its surface against chemical or mechanical damage, but is on the other hand so flexible that the roller can nestle with its surface on uneven strip surfaces with more or less flattening of its circumference.
Durch entsprechende Wahl der Wandstärke des Metallüberzugs und der Elastizität der elastischen Schicht der Walze, die sich aus der Dicke und der Shorehärte der elastischen Schicht ergibt, kann die Walze auf die geforderten Bedingungen entsprechend eingestellt sein. Dabei kann die elastische Schicht entsprechend den Erfordernissen aus einem elastischeren oder weniger elastischen Material, z.B. aus einem weicheren oder einem härteren Gummi oder Kunststoff bestehen. Bei Ausbildung aus Kunststoff wird zweckmäßig ein unverstärkter Kunststoff, also ein solcher gewählt, der frei von Verstärkungs- oder Versteifungseinlagen ist. Eine Anpassung der Elastizität der Walzenoberfläche an die gewünschten Erfordernisse kann aber auch dadurch erreicht werden, daß innerhalb der elastischen Schicht Hohlräume vorhanden sind, welche an eine pneumatische oder hydraulische Druckquelle angeschlossen oder anschließbar sind und über diese Quelle unter Druck gesetzt werden können. Hierdurch kann man eine stufenlose Anpassung der elastischen Schicht der Walze an die gewünschte Schichthärte erzeugen.By appropriate selection of the wall thickness of the metal coating and the elasticity of the elastic layer of the roller, which results from the thickness and the Shore hardness of the elastic layer, the roller can be adjusted to the required conditions. The elastic layer can consist of a more elastic or less elastic material, for example of a softer or a harder rubber or plastic, depending on the requirements. When training from plastic is expedient unreinforced plastic, so chosen one that is free of reinforcement or stiffening inserts. An adaptation of the elasticity of the roller surface to the desired requirements can also be achieved in that there are cavities within the elastic layer, which are connected or can be connected to a pneumatic or hydraulic pressure source and can be pressurized via this source. This enables a continuous adjustment of the elastic layer of the roller to the desired layer hardness.
Der Metallmantel hat vorzugsweise eine Wandstärke von 0,1 bis 1,0 mm und kann z.B. aus Chrom, Nickel oder Edelstahl bestehen. Die elastische Schicht kann dagegen eine Dicke von 5 bis 70 mm, vorzugsweise 15 bis 30 mm haben.The metal jacket preferably has a wall thickness of 0.1 to 1.0 mm and can e.g. made of chrome, nickel or stainless steel. In contrast, the elastic layer can have a thickness of 5 to 70 mm, preferably 15 to 30 mm.
Durch DE 35 25 045 A1 ist zwar auch eine Walze für Druckmaschinen bekannt geworden, deren im wesentlichen biegesteifer Grundkörper mit einem Überzug aus Keramik oder Metall versehen ist. Diese Walze soll bei leichtem Gewicht einer möglichst geringen Durchbiegung unterliegen und hat auch wegen Fehlens einer elastischen Schicht am Walzenumfang auch an ihrer Oberfläche eine geringe Elastizität. Sie ist daher nicht in der Lage, in Bandbeschichtungsanlagen einen über die gesamte Bandbreite gleichmäßig dicken Beschichtungsauftrag zu gewährleisten.From DE 35 25 045 A1, a roller for printing presses is also known, the essentially rigid base body of which is provided with a coating of ceramic or metal. This roller should be subject to the least possible deflection with a light weight and also has a low elasticity on its surface due to the lack of an elastic layer on the roller circumference. It is therefore not in a position to guarantee a coating application that is uniformly thick over the entire range in coil coating systems.
Gleiches gilt für bekannte Druckwalzen mit einem Stahlkern und einem Mantel aus Kupfer oder Acrylglas, der entsprechend dem herzustellenden Druck graviert wird (DE 35 11 478 A1).The same applies to known pressure rollers with a steel core and a jacket made of copper or acrylic glass, which is engraved according to the pressure to be produced (DE 35 11 478 A1).
Die Erfindung betrifft auch ein Verfahren zum Aufbringen des metallischen Überzugs in Form eines Metallmantels auf die elastische Schicht der Walze. Erfindungsgemäß werden bei diesem Verfahren vor dem Aufbringen des Metallmantels zunächst die elastische Schicht gekühlt und der Metallmantel erwärmt. Bei dem anschließenden Temperaturausgleich preßt sich der Metallmantel auf die elastische Schicht auf und erhält damit einen abgestimmten Schrumpfsitz auf dieser Schicht.The invention also relates to a method for applying the metallic coating in the form of a metal jacket to the elastic layer of the roller. According to the invention, in this process, before the metal jacket is applied first the elastic layer is cooled and the metal jacket is heated. During the subsequent temperature equalization, the metal jacket presses onto the elastic layer and thus receives a coordinated shrink fit on this layer.
Die Verbindung zwischen Mantel- und elastischer Schicht kann auch durch eine Verklebung mittels eines elastischen Haftvermittlers geschehen.The connection between the sheath and elastic layer can also be done by gluing using an elastic adhesive.
Im folgenden wird ein besonders vorteilhaftes Ausführungsbeispiel der erfindungsgemäßen Walze anhand der Zeichnung näher beschrieben:
Die im Längsschnitt dargestellte Walze besitzt einen Grundkörper 1 aus einem biegesteifen Stahlrohr, das an seinen Enden über Naben 2 an Achsstummeln 3 sitzt. Auf diesem Rohr ist eine elastische Schicht 4 aus Gummi oder Kunststoff aufgebracht, die an ihrer Außenseite einen dünnen, biegsamen Metallüberzug 5 trägt. Dieser Metallüberzug ist von einem Metallmantel gebildet, der auf die elastische Schicht mit Schrumpfsitz aufgebracht ist. Aufgrund des dünnen, biegsamen Metallüberzuges 5 ist die beschriebene Walze in der Lage, sich über ihre gesamte axiale Länge an unebene Oberflächen von zu beschichtenden Bändern anzuschmiegen, um dadurch einen über die gesamte Bandbreite gleichmäßig dicken Beschichtungsauftrag zu gewährleisten. Ein weiterer Vorteil der erfindungsgemäßen Walze liegt darin, daß ihr Metallüberzug dem Einsatz der Walze entsprechend mit einer Rasterung oder sonstigen Profilierung versehen sowie mit Hilfe der Dünnschicht- oder auch Dickschichttechnologie in seiner Oberflächenhärte entsprechend den jeweiligen Anforderungen eingestellt werden kann. Hier kommen auch Beschichtungen, z.B. mit Keramik oder Titannitrid, oder auch andere Oberflächenbehandlungen in Frage.A particularly advantageous exemplary embodiment of the roller according to the invention is described in more detail below with reference to the drawing:
The roller shown in longitudinal section has a
Die erfindungsgemäße Walze kann nicht nur in Bandanlagen eingesetzt werden, sondern auch überall da, wo Walzen oder Rollen mit elastischen oder nachgiebigen Oberflächen benötigt werden, die einem Verschleiß oder chemischen Angriff unterliegen. So kann beispielsweise die erfindungsgemäße Walze als Presseur-Walze, Abquetschwalze, als Tauchrolle in Bandbehandlungsanlagen, als Dämpfrolle oder als verschleißgeschützte "weiche" Walze in Coil-Coating- oder Bedruckungsverfahren eingesetzt werden.The roller according to the invention can be used not only in belt systems, but also wherever rollers or rollers with elastic or resilient surfaces are required which are subject to wear or chemical attack. For example, the roller according to the invention can be used as an impression roller, squeeze roller, as an immersion roller in belt treatment plants, as a damping roller or as a wear-protected “soft” roller in coil coating or printing processes.
