Abstract
Description
Die
Erfindung betrifft eine Vorrichtung zur Lagerung einer Walze, insbesondere
für Rotationsdruckmaschinen.
Die Walze weist endseitig jeweils einen Wellenzapfen auf, der üblicherweise
in einem Lünetten-Lager
gelagert ist. Die Vorzüge
eines Lünetten-Lagers
werden beispielsweise in
Vor der Inbetriebnahme einer Druckwalze ist eine exakte Ausrichtung und Positionierung der Walze relativ zu dem zu bedruckenden Medium und/oder relativ zu einem Walzenantrieb erforderlich. Zu berücksichtigen ist, dass die Walzen in der Praxis unterschiedlich große Wellenzapfen aufweisen. Zur Anpassung an unterschiedliche Wellenzapfen werden Adapter verwendet. Adapterlösungen haben jedoch funktionsmäßige Nachteile. Ferner ist ihre Montage aufwendig.In front the commissioning of a pressure roller is an exact alignment and positioning the roller relative to the medium to be printed and / or relative to a roller drive required. To be considered is that the rollers in practice different sized shaft journals exhibit. To adapt to different shaft journals are adapters used. adapter solutions however, have functional disadvantages. Furthermore, their assembly is expensive.
Des
Weiteren ist bekannt Lünetten-Lager verstellbar
auszuführen.
So beschreibt die
Vor diesem Hintergrund liegt der Erfindung die Aufgabe zugrunde, eine Vorrichtung zur Lagerung von Walzen mit unterschiedlichen Wellenzapfen anzugeben, die keine auf den Wellenzapfen zu montierende Adapter erfordert, sowie eine einfache und belastbare Konstruktion aufweist.In front In this background, the invention is based on the object Specify device for supporting rolls with different journals, which does not require an adapter to be mounted on the shaft journal, and has a simple and durable construction.
Gegenstand der Erfindung und Lösung dieser Aufgabe ist eine Vorrichtung zur Lagerung einer Walze mit einer an einem Maschinengestell befestigbaren, quaderförmigen Lagerkassette, in der zwei Rollen mit einem vertikalen Versatz zur horizontalen Symmetrieebene der Lagerkassetten nebeneinander drehbar gelagert sind, sowie mit Spannelementen zur Befestigung der Lagerkassette am Maschinengestell, wobei die Lagerkassette als Wendekassette ausgebildet ist und sowohl an ihrer Oberseite als auch an ihrer Unterseite Kontaktflächen zur wechselseitigen Auflage am Maschinengestell aufweist und wobei die Rollen an der Oberseite und der Unterseite der Lagerkassette hervorstehen, so dass sie an beiden Seiten als Lünetten-Lager für den Wellenzapfen einer Walze nutzbar sind.object the invention and solution This object is a device for supporting a roller with an attachable to a machine frame, cuboid storage cassette, in the two rollers with a vertical offset to the horizontal plane of symmetry the storage cassettes are mounted side by side rotatable, and with Clamping elements for fastening the storage cassette to the machine frame, wherein the storage cassette is designed as a reversing cassette and both on its top and on its underside contact surfaces for has mutual support on the machine frame and wherein the Rollers protrude from the top and bottom of the storage cassette, leaving it on both sides as a lunette bearing for the shaft journal of a Roller are usable.
Durch Wenden um 180° ist die Lagerkassette zur Lagerung einer zweiten Walze einsetzbar.By Turn by 180 ° the storage cassette for storage of a second roller used.
Der vertikale Versatz der Rollen bezogen auf die horizontale Symmetrieebene der Lagerkassette ist vorzugsweise auf den Zapfendurchmesser von zwei wechselweise einzusetzenden Walzen so abgestimmt, dass die Walzenachse der mit einem kleineren Zapfen versehenen Walze und die Walzenachse der mit einem größeren Zapfen versehenen Walze dieselbe Position einnehmen, wenn die Walzen in der Lagerkassette gelagert werden und die Lagerkassette zur Lagerung der zweiten Walze gewendet worden ist. Das Kriterium ist zumindest näherungsweise erfüllt, wenn der vierfache Betrag des vertikalen Versatzes der Rollen bezogen auf die horizontale Symmetrieebene der Lagerkassette der Differenz der Zapfendurchmesser der zu lagernden Wellenzapfen entspricht. Durch Wenden der Lagerkassette wird erreicht, dass die Lagerachsen der beiden Walzen innerhalb der Druckmaschine eine gleiche, vorgegebene Position einnehmen.Of the vertical offset of the rollers relative to the horizontal plane of symmetry the storage cassette is preferably on the pin diameter of two alternately used rollers tuned so that the roll axis the roller provided with a smaller pin and the roller axis of with a larger cone provided roll take the same position when the rollers in the storage cassette are stored and the storage cassette for storage the second roller has been turned. The criterion is at least approximately Fulfills, when four times the amount of vertical displacement of the rollers on the horizontal plane of symmetry of the storage cassette of the difference the journal diameter of the shaft journal to be stored corresponds. By turning the storage cassette is achieved that the bearing axes the two rollers within the printing press an equal, predetermined To take position.
Die als Wendekassette ausgebildete erfindungsgemäße Lagerkassette ist durch Spannelemente in vertikaler Richtung und in mindestens einer horizontalen Richtung kraftschlüssig an Auflageflächen des Maschinengestells passgenau fixierbar und wieder lösbar. Die Spannelemente sind vorzugsweise als Keilspanner ausgebildet. Die Keilspanner weisen einen Andruckschuh auf, der mit einem schräg angeordneten Befestigungselement zusammenwirkt. Die Lagerkassette ist mittels der Andruckschuhe gegen Auflageflächen des Maschinengestells spannbar.The formed as a reversing cassette storage cassette according to the invention is through Clamping elements in the vertical direction and in at least one horizontal Direction non-positive on bearing surfaces of the machine frame accurately fixed and released again. The Clamping elements are preferably designed as wedge clamps. The Wedge clamps have a pressure shoe, which is arranged at an angle Fastening element cooperates. The storage cassette is by means of the Andruckschuhe against bearing surfaces of the machine frame tensioned.
