Die erste Bearbeitungseinheit 9 ist auf einem ersten Schlitten 91 angeordnet. Mit diesem fest verbunden ist ein erster Motor 92, der eine erste Spindelschraube 93 antreibt. Die erste Spindelschraube 93 steht mit der feststehenden Spindel 8 in Wirkverbindung. Auf dem erster Schlitten 91 sind weiterhin als Löscheinrichtung ein Löschkopf 94 und eine Absaugung 95 mit einer Absaugschlauch 96 angeordnet. Der Löschkopf 94 ist als Hochenergielaser ausgeführt. Dabei muss (in Bewegungsrichtung des ersten Schlittens 91 gesehen - siehe Pfeil) der Löschkopf 94 vor der Absaugung 95 angeordnet sein.The first processing unit 9 is arranged on a first slide 91. Firmly connected to this is a first motor 92 that drives a first spindle screw 93. The first spindle screw 93 is in operative connection with the fixed spindle 8. On the first slide 91 are still a quenching head 94 and a suction 95 with a suction hose 96 are arranged as the extinguishing device. The erase head 94 is designed as a high-energy laser. It must (in the direction of movement of the seen first slide 91 - see arrow) the extinguishing head 94 may be arranged in front of the suction 95.

Der Bearbeitungseinheit 9 nachgeordnet (in Bewegungsrichtung der Bearbeitungseinheiten 9, 10, 11 gesehen) ist die zweite Bearbeitungseinheit 10. Diese ist ebenfalls auf einem Schlitten 101 angeordnet und weist einen Motor 102 und eine Spindelschraube 103 in der gleichen Konfiguration auf. Dieser Schlitten 101 trägt hier eine Beschichtungseinheit 104. Die Beschichtungseinheit 104 ist als ein Tintenstrahlkopf ausgeführt.Downstream of the processing unit 9 (in the direction of movement of the processing units 9, 10, 11 seen) is the second processing unit 10. This is also arranged on a carriage 101 and has a motor 102 and a spindle screw 103 in the same configuration. This Carriage 101 carries a coating unit 104 here. The coating unit 104 is in the form of an inkjet head executed.

Die nächste und in diesem Ausführungsbeispiel die letzte Bearbeitungseinheit 11 in (technologischer) Folge ist die dritte Bearbeitungseinheit 11. Diese besteht analog zu den oben beschriebenen Bearbeitungseinheiten 9; 10 aus einem Motor 112 mit einer Spindelschraube 113. Dem Schlitten 111 zugeordnet sind eine Bebilderungseinrichtung und eine Fixiereinrichtung 115.The next and in this embodiment the last processing unit 11 in (technological) The result is the third processing unit 11. This is analogous to the processing units described above 9; 10 from a motor 112 with a spindle screw 113. Assigned to the slide 111 are an imaging device and a fixing device 115.

In den Figuren 1 und 2, an Hand derer das Ausführungsbeispiel beschrieben wird, sind die erforderlichen Versorgungskabel und Versorgungsschläuche nicht eingezeichnet. Das soll die Darstellung vereinfachen.In Figures 1 and 2, on the basis of which the embodiment is described, the required Supply cable and supply hoses not shown. This should simplify the presentation.

Nachfolgend wird die Wirkungsweise des oben beschrieben Ausführungsbeispieles erläutert.The mode of operation of the exemplary embodiment described above is explained below.

Bei Beginn der Bebilderung befinden sich die in diesem Falle drei Bearbeitungseinheiten 9; 10; 11 in ihrer Parkposition an der Gehäusewand 6. Dabei werden sie teilweise oder vollständig vom Lagergehäuse 121 aufgenommen.At the beginning of the imaging, there are three processing units 9 in this case; 10; 11 in their parking position on the housing wall 6. They are partially or completely removed from the bearing housing 121 added.

Zur Durchführung der Bebilderung fährt die erste Bearbeitungseinheit 9 in Pfeilrichtung zum Plattenzylinder 1. Dazu wird der Motor 92 in Betrieb genommen. Dieser dreht die Spindelschraube 93. Da die Spindel 8 drehfest ist, wird somit der Schlitten 91 in die gewünschte Richtung bewegt. Der Plattenzylinder 1 rotiert in einer der Bearbeitung angepassten Geschwindigkeit.To carry out the imaging, the first processing unit 9 travels in the direction of the arrow to the plate cylinder 1. The motor 92 is started up for this purpose. This turns the screw 93. Da the spindle 8 is non-rotatable, the carriage 91 is thus moved in the desired direction. The plate cylinder 1 rotates at a speed adapted to the machining.

Beim Erreichen des Plattenzylinders 1 wird der Löschkopf 94 aktiviert. Der Laser des Löschkopfes 94 löscht die vom vorhergehendem Auftrag verbliebene Bildinformation bzw. entfernt die auf dem Plattenzylinder 1 vorhandene Schicht. Die Absaugung 95 nimmt die abgelösten Partikel auf und führt diese aus dem Bereich der Druckmaschine. Nach dem vollständigen Ablösen der alten Bebilderung und Erreichen der gegenüberliegenden Randzone des Plattenzylinders 1 nimmt die erste Bearbeitungseinheit 9 dort ihre Parkposition im Bereich der Gehäusewand 6 ein. Dafür ist ein analog zum Lagergehäuse 121 aufgebautes Lagergehäuse 122 vorgesehen.When the plate cylinder 1 is reached, the erase head 94 is activated. The laser of the erase head 94 deletes the image information remaining from the previous job or removes the information on the plate cylinder 1 existing shift. The suction 95 picks up the detached particles and guides them these from the field of the printing press. After the old images have been completely removed and reaching the opposite edge zone of the plate cylinder 1 takes the first processing unit 9 there their parking position in the area of the housing wall 6. For this is an analog to the bearing housing 121 built bearing housing 122 is provided.

Die so vorbereitete Oberfläche des Plattenzylinders 1 wird nunmehr durch die Beschichtungseinheit 104 der zweiten Bearbeitungseinheit 10 mit einer bebilderbaren Schicht versehen. Die Bewegung der zweiten Bearbeitungseinheit 10 wird analog zur ersten Bearbeitungseinheit 9 realisiert. Die Einleitung dieses Vorgangs erfolgt in der Regel unmittelbar nach dem Ablösen der alten Schicht bzw. der alten Bildinformation. Nach erfolgreicher Beschichtung nimmt die zweite Bearbeitungseinheit 10 ebenfalls ihre Parkposition (wie oben beschrieben) auf der anderen Seite ein.The surface of the plate cylinder 1 thus prepared is now covered by the coating unit 104 of the second processing unit 10 is provided with an imageable layer. The movement the second processing unit 10 is implemented analogously to the first processing unit 9. The introduction this process usually takes place immediately after the old layer or the old image information. After successful coating, the second processing unit 10 also enter their parking position (as described above) on the other side.

Als letzte Bearbeitungsstation wird nunmehr die dritte Bearbeitungseinheit 11 in Betrieb genommen. Das erfolgt nach Aushärtung der aufgebrachten Schicht in der dazu erforderlichen Zeit. Die dritte Bearbeitungseinheit 11 bewegt sich in analoger Weise über die Oberfläche des Plattenzylinders 1. Dabei wird über den Laser der Bebilderungseinheit 114 die aktuelle Bildinformation aufgeprägt und durch die Fixiereinrichtung 115 ausgehärtet.The third processing unit 11 is now put into operation as the last processing station. This takes place after the applied layer has hardened in the time required for this. The third processing unit 11 moves in an analogous manner over the surface of the plate cylinder 1 the current image information is impressed by the laser of the imaging unit 114 and by the fixing device 115 cured.

Nach der erfolgten Bebilderung haben die Bearbeitungseinheiten 9; 10; 11 ihre Parkposition an der gegenüberliegenden Seite eingenommen. Der Druckvorgang kann nunmehr erfolgen. Vorteilhaft ist es jedoch, die Bearbeitungseinheiten 9; 10; 11 vor dem Druckvorgang auf ihren Ausgangspunkt zurückzufahren. Das erfolgt in einer Geschwindigkeit, die ein Mehrfaches der Bearbeitungsgeschwindigkeit entspricht. Auch können die Bearbeitungseinheiten 9; 10; 11 unmittelbar hintereinander bzw. im Komplex bewegt werden.After the imaging has taken place, the processing units 9; 10; 11 their parking position at the opposite side. The printing process can now take place. It is advantageous however, the processing units 9; 10; 11 return to their starting point before printing. This is done at a speed that is a multiple of the processing speed equivalent. The processing units 9; 10; 11 in immediate succession or in Complex moving.

Die oben beschriebene Lösung stellt nur eine denkbare Ausführung dar. Es ist ebenfalls möglich, nach der zweiten Bearbeitungseinheit 10 zum Beispiel eine weitere Bearbeitungseinheit einzufügen oder mit dieser zu integrieren, welche die Schicht (wenn technologisch erforderlich) aushärtet. Ebenfalls kann nach der dritten Bearbeitungseinheit 11 eine Station zum Reinigen bzw. zum Entwickeln der Oberfläche eingefügt werden.The solution described above is only a conceivable embodiment. It is also possible to to insert, for example, a further processing unit into the second processing unit 10 to integrate with this, which hardens the layer (if technologically necessary). Likewise can after the third processing unit 11 a station for cleaning or for developing the Surface to be inserted.

In der Figur 3 ist die Parkposition der Bearbeitungseinheiten nach erfolgter Bebilderung dargestellt. Aus der Figur ist auch eine weitere Ausführung der Erfindung erkennbar. Dabei sind die Bearbeitungseinheiten 9'; 10'; 11' mit Linearmotoren 131, 141, 151 ausgerüstet. Diese stehen über Antriebsglieder 132; 142; 152 mit der Traverse 71 in Verbindung.FIG. 3 shows the parking position of the processing units after the imaging has taken place. A further embodiment of the invention can also be seen from the figure. Here are the processing units 9 '; 10 '; 11 'equipped with linear motors 131, 141, 151. These are above drive links 132; 142; 152 with the traverse 71 in connection.

Die Wirkungsweise dieser Ausführung entspricht der oben beschriebenen.The operation of this version corresponds to that described above.

In der Figur 4 ist eine Ausführung mit zwei Traversen 72, 73 dargestellt. Vorteilhaft hierbei ist, dass insbesondere bei Ausführungen mit einer größeren Anzahl von Bearbeitungsstationen diese sinnvoll auf die beiden Traversen 72, 73 aufgeteilt werden können, so dass sich bessere Platzverhältnisse und bessere Verhältnisse in Bezug auf die Parkpositionen in der Nähe der Gehäusewand 6 ergeben. Dabei können die Bearbeitungsstationen sowohl mit Linearmotoren 131; 141, 151 als auch mit Motoren 92, 102, 112 ausgestattet sein. FIG. 4 shows an embodiment with two cross members 72, 73. The advantage here is that this makes sense especially for versions with a larger number of processing stations can be divided between the two trusses 72, 73, so that there is better space and result in better conditions with regard to the parking positions in the vicinity of the housing wall 6. there can the machining stations with linear motors 131; 141, 151 as well as with motors 92, 102, 112.
