Abstract
Eine Vorrichtung zum Reinigen eines Druckbalkens (2) für Inkjet umfasst ein Reinigungsstation 3 mit einem Reinigungsschlitten (7) zum Reinigen des Druckbalkens (2), einer Schlittenführung (8) zum Führen des Reinigungsschlittens (7) entlang des Druckbalkens (2) und einer Führungsfederung (11) zum Drücken der Schlittenführung (8) zu dem Druckbalken (2). Außerdem umfasst die Vorrichtung eine Balkenführung zum Führen des Druckbalkens (2) zu der Reinigungsstation (3). Die Balkenführungen können beispielsweise eine X-Y-Führung sein. An apparatus for cleaning a pressure bar (2) for inkjet comprises a cleaning station 3 with a cleaning carriage (7) for cleaning the pressure bar (2), a carriage guide (8) for guiding the cleaning carriage (7) along the pressure bar (2) and a guide suspension (11) for pressing the carriage guide (8) to the pressure bar (2). In addition, the device comprises a bar guide for guiding the pressure bar (2) to the cleaning station (3). The bar guides may be, for example, an XY guide.
Description
Vorliegende Erfindung betrifft eine Vorrichtung zum Reinigen eines Druckbalkens für Inkj et.The present invention relates to a device for cleaning a pressure bar for Inkj et.
In
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine weitere Vorrichtung zum Reinigen eines Druckbalkens zu schaffen.The present invention has for its object to provide a further device for cleaning a pressure beam.
Diese Aufgabe wird durch eine Vorrichtung mit den Merkmalen des Anspruchs 1 gelöst. Die erfindungsgemäße Vorrichtung zum Reinigen eines Druckbalkens für Inkjet umfasst eine Reinigungsstation mit einem Reinigungsschlitten zum Reinigen des Druckbalkens, einer Schlittenführung zum Führen des Reinigungsschlittens entlang des Druckbalkens und einer Führungsfederung zum Drücken der Schlittenführung zu den Druckbalken und umfasst weiterhin eine Balkenführung zum Führen des Druckbalkens zu der Reinigungsstation.This object is achieved by a device having the features of
Die Erfindung hat verschiedene Vorteile. Der Bereich des Druckens und der Bereich des Reinigens sind voneinander klar getrennt und beeinträchtigen sich nicht gegenseitig. Es ist eine hohe Flexibilität bezüglich möglicher Änderungen der Reinigungsparameter gegeben. Beispielsweise sind mehrfache Reinigungsfahrten des Reinigungsschlittens bei der Reinigung möglich. Der Reinigungsschlitten kann mit einem Schlittenaufsatz ausgestattet sein, welcher modular aufgebaut ist. Es besteht eine große Freiheit in der Bestückung des Reinigungsschlittens mit funktionalen Einheiten. Beispielsweise kann vorgesehen sein, dass eine für eine kontaktlose Reinigung vorhandene Waschmittel-Sprühdüsen-Einheit gegen eine Waschtuch-Einheit ausgetauscht wird, die beim Reinigen mit Wischkontakt arbeitet. Die Reinigungsstation kann als eine geschlossene Box ausgebildet werden, in welcher eine Nebelabsaugung möglich ist. Der Pflege- und Wartungsaufwand für die Reinigungsstation und für den Druckbalken sind gering. Es erfolgt eine selbsttätige, einfache Ausrichtung der Reinigungsstation auf den Druckbalken, so dass keine aufwändige Justage erforderlich ist.The invention has several advantages. The area of printing and the area of cleaning are clearly separated from each other and do not interfere with each other. There is a high flexibility regarding possible changes of the cleaning parameters. For example, multiple cleaning trips of the cleaning slide during cleaning are possible. The cleaning carriage may be equipped with a carriage attachment, which is modular. There is a great freedom in equipping the cleaning carriage with functional units. For example, it can be provided that an existing for a contactless cleaning detergent spray nozzle unit is replaced by a washing cloth unit that works with cleaning wiping contact. The cleaning station can be designed as a closed box in which a mist extraction is possible. The care and maintenance for the cleaning station and for the pressure bar are low. There is an automatic, simple alignment of the cleaning station on the pressure bar, so that no time-consuming adjustment is required.
Es sind verschiedene Weiterbildungen möglich. Die Balkenführung kann eine X-Y-Führung sein. Der Reinigungsschlitten kann ein Waschschlitten sein. Hierbei erfolgt eine Feuchtreinigung des Druckbalkens unter Zuhilfenahme eines Waschfluids. Die Schlittenführung kann einen Distanzhalter zum Halten einer Distanz zwischen dem Reinigungsschlitten und dem Druckbalken aufweisen. Die Führungsfederung kann ein Blattfedersystem sein. Die Reinigungsstation kann eine Schlittenfederung zum Drücken des Reinigungsschlittens gegen die Schlittenführung aufweisen. Die Schlittenfederung kann ein Blattfedersystem sein. Die Reinigungsstation kann ein Gehäuse mit einer ersten Kammer und einer zweiten Kammer aufweisen. In der ersten Kammer kann der Reinigungsschlitten angeordnet sein und in der zweiten Kammer kann ein Antriebssystem zum Antreiben des Reinigungsschlittens angeordnet sein. Ein Verbindungsarm zum Verbinden des Antriebssystems mit dem Reinigungsschlitten kann aus der ersten Kammer in die zweite Kammer hinein ragen.There are various developments possible. The beam guide may be an X-Y guide. The cleaning carriage may be a wash carriage. Here, a wet cleaning of the pressure bar with the aid of a washing fluid. The carriage guide may include a spacer for maintaining a distance between the cleaning carriage and the pressure beam. The guide suspension may be a leaf spring system. The cleaning station may have a carriage spring for pressing the cleaning carriage against the carriage guide. The carriage suspension may be a leaf spring system. The cleaning station may include a housing having a first chamber and a second chamber. The cleaning carriage may be arranged in the first chamber and a drive system for driving the cleaning carriage may be arranged in the second chamber. A connecting arm for connecting the drive system to the cleaning carriage may protrude from the first chamber into the second chamber.
