Description
Vorrichtung zur Stromübertraqung Device for power transmission
Die Erfindung bezieht sich auf das Gebiet der elektronischen Reproduktionstechnik und betrifft eine Vorrichtung zur Übertragung von Strömen von mindestens einer Stromquelle an mindestens eine bewegliche Einheit in einem elektronischen Reproduktionsgerät, insbesondere in einer Graviermaschinen zur Gravur von Druckformen. Die Erfindung betrifft außerdem ein elektronisches Reproduktionsgerät, insbesondere eine elektronische Graviermaschine, mit einer derartigen Stromübertragungsvorrichtung.The invention relates to the field of electronic reproduction technology and relates to a device for transmitting currents from at least one power source to at least one movable unit in an electronic reproduction device, in particular in an engraving machine for engraving printing forms. The invention also relates to an electronic reproduction device, in particular an electronic engraving machine, with such a power transmission device.
In einer elektronischen Graviermaschine zur Gravur von Druckzylindern bewegt sich ein Gravierorgan, beispielsweise ein elektromagnetisches Gravierorgan mit einem Gravierstichel als Schneidwerkzeug, in axialer Richtung an einem rotierenden Druckzylinder entlang. Der von einem Graviersteuersignal gesteuerte Gra- vierstichel schneidet eine Folge von in einem Gravurraster angeordneten Näpfchen in die Mantelfläche des rotierenden Druckzylinders.In an electronic engraving machine for engraving printing cylinders, an engraving element, for example an electromagnetic engraving element with an engraving stylus as a cutting tool, moves in the axial direction along a rotating printing cylinder. The engraving control, which is controlled by an engraving control signal, cuts a sequence of cups arranged in an engraving grid into the outer surface of the rotating printing cylinder.
Für den Publikationsdruck müssen auf einem Druckzylinder eine Vielzahl von axial nebeneinander liegenden Graviersträngen mit jeweils einem Gravierorgan graviert werden. Jedes Gravierorgan ist auf einem separaten Graviersupport angeordnet. Die einzelnen Graviersupporte sind auf einem gemeinsamen Gravierwagen in axialer Richtung verschiebbar und arretierbar moniert, um vor der Gravur die Abstände der Gravierorgane voneinander entsprechend der Breite der Gravierstränge einzustellen. Der Gravierwagen mit den auf den Graviersupporten befindlichen Gravierorganen wird mittels einer Spindel und eines Vorschubantriebs zur flächenhaften Gravur kontinuierlich oder schrittweise axial an dem Druckzylinder entlang bewegt.For publication printing, a large number of axially adjacent engraving strands, each with an engraving element, must be engraved on a printing cylinder. Each engraving element is arranged on a separate engraving support. The individual engraving supports are mounted on a common engraving carriage in the axial direction and can be locked in place in order to adjust the spacing of the engraving elements from one another in accordance with the width of the engraving strands before the engraving. The engraving carriage with the engraving elements located on the engraving supports is moved continuously or step-by-step axially along the printing cylinder by means of a spindle and a feed drive for extensive engraving.
In der Graviermaschine müssen Betriebsströme und Signalströme an bewegliche Einheiten, beispielsweise an die auf den beweglichen Graviersupporten montierten Gravierorgane übertragen werden. Bei herkömmlichen Graviermaschinen erfolgt die Übertragung und Verteilung der Ströme über eine Vielzahl von Kabeln, beispielsweise mit Hilfe von flexiblen Kabelketten. Insbesondere bei Verwendung einer großen Anzahl von Gravierorganen für die Gravur der Gravierstränge im Publikationsdruck sind zahlreiche Kabel und Kabelbäume erforderlich, die in nachteiliger Weise viel Platz benötigen und die axiale Positionierung der Graviersup- porte auf die gewünschte Strangbreite behindern. Durch die Verwendung von Multiplexkabeln kann der Platzbedarf nicht genügend reduziert und die axiale Beweglichkeit der Graviersupporte erhöht werden.In the engraving machine, operating currents and signal currents have to be transmitted to movable units, for example to the engraving members mounted on the movable engraving supports. In conventional engraving machines, the transmission and distribution of the currents takes place via a large number of cables for example with the help of flexible cable chains. In particular when using a large number of engraving elements for engraving the engraving strands in publication printing, numerous cables and wiring harnesses are required, which disadvantageously take up a lot of space and hinder the axial positioning of the engraving supports on the desired strand width. The use of multiplex cables means that the space requirement cannot be reduced sufficiently and the axial mobility of the engraving supports can be increased.
Aufgabe der vorliegenden Erfindung ist es daher, eine Vorrichtung zur Übertra- gung von Strömen von mindestens einer Stromquelle an mindestens eine bewegliche Einheit in einem elektronischen Reproduktionsgerät, insbesondere in einer Graviermaschine zur Gravur von Druckzylindern, sowie ein Reproduktionsgerät, vorzugsweise eine Graviermaschine, mit einer solchen Stromübertragungsvorrichtung derart zu verbessern, daß die Übertragung und Verteilung von Betriebs- strömen und/oder Signalströmen an die bewegliche Einheit bei kleinem Raumbedarf für die Übertragungselemente und möglichst ohne Einschränkung der Beweglichkeit der Einheit erfolgt.It is therefore an object of the present invention to provide a device for transmitting currents from at least one power source to at least one movable unit in an electronic reproduction device, in particular in an engraving machine for engraving printing cylinders, and a reproduction device, preferably an engraving machine, with such a device To improve the current transmission device in such a way that the transmission and distribution of operating currents and / or signal currents to the movable unit takes place with a small space requirement for the transmission elements and, as far as possible, without restricting the mobility of the unit.
Unter Einheit soll eine Baueinheit oder eine Funktionseinheit eines Reprodukti- onsgerätes, beispielsweise eines Vorlagenabtastgerätes, eines Aufzeichnungsgerätes oder einer Graviermaschine, verstanden werden. Eine Stromquelle soll beispielsweise eine Betriebsstromquelle oder eine Signalstromquelle umfassen, wobei ein Betriebsstrom zur elektrischen Versorgung und ein Signalstrom zur Steuerung der Bau- oder Funktionseinheit dient.A unit is to be understood as a structural unit or a functional unit of a reproduction device, for example a document scanner, a recording device or an engraving machine.
