Abstract

The sleeve carries a piezoelectric polymer foil on its inner wall with internal dia. in the no current or voltage state ensuring a force-locking seating on the roller or plug. The polymer foil is permanently attached. i.e. stuck, to the inner wall of the sleeve.

Description

Die Erfindung betrifft eine Walze oder einen Dorn mit austauschbarem Mantel, vor­ zugsweise eine Druck- oder Rasterwalze mit austauschbarem Druck- oder Raster­ walzenmantel.The invention relates to a roller or a mandrel with an exchangeable jacket preferably a printing or anilox roller with exchangeable printing or anilox roller jacket.

Insbesondere bei Druckmaschinen ist es erforderlich, auf die Druck- oder Raster­ walzen Mäntel mit unterschiedlichen Klischees bzw. Profilen aufzuziehen. Da die Mäntel mit Vorspannung auf den diese tragenden Walzen sitzen, um die erforderli­ che kraftschlüssige Verbindung zu gewährleisten, ist der Austausch der Mäntel oder Sleeves aufwendig und schwierig.Particularly in the case of printing machines, it is necessary to click on the printing or screen roll up coats with different clichés or profiles. Since the Pre-tensioned coats sit on the rollers that support them in order to The exchange of the coats is to ensure a positive connection or sleeves complex and difficult.

Aus der US-PS 4,903,597 ist eine Druckwalze mit einem austauschbaren Druck­ walzenmantel bekannt, bei dem die den Mantel tragende Kernwalze hohl ausgebil­ det und mit einem Druckluftanschluß versehen ist, wobei der Kernwalzenmantel mit radialen Bohrungen versehen ist, so daß zwischen dem Kernwalzenmantel und dem Druckwalzenmantel ein Druckluftpolster erzeugt werden kann, das den Druckwalzenmantel in der Weise aufweitet daß dieser auf den Kernwalzenmantel aufgeschoben und von diesem abgezogen werden kann.From US-PS 4,903,597 is a pressure roller with an exchangeable print roller jacket is known, in which the core roller carrying the jacket is hollow det and is provided with a compressed air connection, the core roll jacket with radial bores is provided so that between the core roll shell and the pressure roller jacket a compressed air cushion can be generated, the Pressure roller jacket expands in such a way that this on the core roller jacket can be postponed and removed from this.

Aufgabe der Erfindung ist es, eine Walze oder einen Dorn der eingangs angegebe­ nen Art vorzuschlagen, auf den sich problemlos und in einfacher Weise ein Mantel (Sleeve) aufschieben und von diesem auch wieder abziehen läßt.The object of the invention is to specify a roller or a mandrel of the beginning to propose a way that can be easily and easily a coat Slide on (sleeve) and have it pulled off again.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß der Mantel auf seiner Innenwandung eine piezoelektrische Polymerfolie trägt, deren innerer Durchmesser im strom- bzw. spannungslosen Zustand einen kraftschlüssigen Sitz auf der Walze oder dem Dorn gewährleistet.According to the invention this object is achieved in that the jacket on his Inner wall carries a piezoelectric polymer film, the inner diameter in current-free or voltage-free state a frictional fit on the roller or the thorn guaranteed.

Piezoelektrische Polymerfolien, die durch Anlegen einer Spannung eine Dehnung, also Längenänderung, erfahren, sind beispielsweise in der DE 34 35 521 A1 und den Veröffentlichungen "neue Sensormaterialien aus Polymerfolien", von Danz, wissenschaft und fortschritt 36 (1986 6, Seiten 139 bis 142) und in "Struktur und Eigenschaften piezo- und pyroelektrischer Polymerfolien", Danz und Geiss, in Acta Polymerica 38 (1987 Nr. 6, Seiten 399 bis 406) beschrieben worden.Piezoelectric polymer films that stretch by applying voltage So change in length, are experienced, for example, in DE 34 35 521 A1 and the publications "new sensor materials from polymer films", by Danz, science and progress 36 (1986 6, pages 139 to 142) and in "Structure and Properties of piezo and pyroelectric polymer films ", Danz and Geiss, in Acta Polymerica 38 (1987 No. 6, pages 399 to 406).

Bei der erfindungsgemäß auf die innere Wandung des austauschbaren Mantels (Sleeves) aufgebrachte Polymerfolie kann der Piezo-Effekt in der Weise ausgenutzt werden, daß sich durch Anlegen einer Spannung die Polymerfolie in Umfangsrich­ tung vergrößert, so daß sie dadurch den Mantel aufweitet und der Mantel von dem Dorn oder dem Walzenkern abgezogen werden kann.In the case of the invention on the inner wall of the exchangeable jacket (Sleeves) applied polymer film, the piezo effect can be exploited in this way be that the polymer film in the circumferential direction by applying a voltage tion enlarged so that it thereby widens the coat and the coat of the Mandrel or the roller core can be removed.

Die Erfindung gibt somit die Verwendung bekannter piezoelektrischer Polymerfolien zum Aufweiten austauschbarer Mäntel an, um diese problemlos auf Walzen oder Dorne aufschieben und von diesen auch wieder abziehen zu können.The invention thus provides the use of known piezoelectric polymer films to expand interchangeable coats to easily roll or Pushing on mandrels and being able to pull them off again.

Um erfindungsgemäß den Piezo-Effekt der piezoelektrischen Polymerfolien ausnut­ zen zu können, sind diese in geeigneter Weise auf die Innenwandung des aus­ tauschbaren Mantels aufzubringen. Dabei können die austauschbaren Mäntel aus dem bisher üblichen Material bestehen. Zweckmäßigerweise wird die Polymerfolie fest mit der Innenwandung des Mantels verbunden. Diese Verbindung kann bei­ spielsweise auch durch Verkleben hergestellt werden.In order to use the piezo effect of the piezoelectric polymer films according to the invention zen, these are in a suitable manner on the inner wall of the interchangeable jacket. The interchangeable coats can the usual material. The polymer film is expediently firmly connected to the inner wall of the jacket. This connection can can also be produced by gluing, for example.
