Wie bereits ausgeführt, ist im gezeigten Ausführungsbeispiel das Handhabungsorgan 28 als Saugeinrichtung ausgebildet, die mehrere Saugdüsen 30 aufweist. Je zwei Saugdüsen 30 dienen dabei der Handhabung einer Druckplatte 16, so dass mit der in Fig. 2 bis 4 gezeigten Saugeinrichtung insgesamt vier Druckplatten gehandhabt werden können. Es sei darauf hingewiesen, dass die Anzahl der vorhandenen Saugdüsen rein exemplarisch ist und von der Anzahl der je Formzylinder handzuhabenden Druckplatten abhängt.As already stated, in the exemplary embodiment shown, the handling member 28 is designed as a suction device which has a plurality of suction nozzles 30. Each two suction nozzles 30 serve to handle a printing plate 16, so that with the in Fig. 2 to 4 shown suction device a total of four printing plates can be handled. It should be noted that the number of available suction nozzles is purely exemplary and depends on the number of plates to be handled per forme cylinder.

Fig. 5 zeigt einen Ausschnitt aus dem als Saugeinrichtung ausgebildeten Handhabungsorgan 28 des Manipulatorkopfs 19 im Bereich von zwei Saugdüsen 30. Die beiden Saugdüsen 30 sind an einem als Platte ausgebildeten Tragelement 31 befestigt, wobei das Tragelement 31 und damit die beiden Saugdüsen 30 im Handhabungsorgan 28 schwimmend gelagert sind. So zeigt Fig. 5 insgesamt vier Kugelrollen 32, wobei zwei Kugelrollen 32 mit einer oberen Seite des Tragelements 31 und zwei Kugelrollen 32 mit einer unteren Seite des Tragelements 31 zusammenwirken. Fig. 5 shows a section of the trained as a suction device handling member 28 of the manipulator head 19 in the region of two suction nozzles 30. The two suction nozzles 30 are fixed to a plate formed as a support member 31, wherein the support member 31 and thus the two suction nozzles 30 are mounted floating in the handling member 28 , So shows Fig. 5 a total of four ball rollers 32, wherein two ball rollers 32 cooperate with an upper side of the support member 31 and two ball rollers 32 with a lower side of the support member 31.

Die mit der Unterseite des Tragelements 31 zusammenwirkenden Kugelrollen 32 sind an einer Traverse 33 des Handhabungsorgans 28 befestigt, die mit der Oberseite des Tragelements 31 zusammenwirkenden Kugelrollen 32 sind hingegen an einer Tragplatte 34 befestigt.The cooperating with the underside of the support member 31 ball rollers 32 are attached to a cross member 33 of the handling member 28, the cooperating with the top of the support member 31 ball rollers 32, however, are fastened to a support plate 34.

Mit den Kugelrollen 32 wirken Fixierbolzen 35 einer Fixiereinrichtung zusammen, die in Richtung der Pfeile 36 axial verschiebbar sind. Die Fixierbolzen 35 durchdringen das Tragelement 31 sowie die Traverse 33 und sind in der Traverse 33 zugeordneten Führungselementen 37 geführt. In der Darstellung der Fig. 5 geben die Fixierbolzen 35 die schwimmende Lagerung der beiden Saugdüsen 30 frei, so dass demnach das Tragelement 31 zusammen mit den Saugdüsen 30 in gewissem Umfang kippbar ist. Zur Fixierung des Tragelements 31 und damit zur Blockierung der schwimmenden Lagerung der Saugdüsen 30 werden die Fixierbolzen 35 gegenüber der in Fig. 5 dargestellten Position nach unten bewegt, so dass den Fixierbolzen 35 zugeordnete Phasen 38 in entsprechende Phasen des Tragelements 31 eingreifen. Dann, wenn Druckplatten 16 aufgenommen und transportiert werden sollen, blockieren die Fixierbolzen 35 die schwimmende Lagerung des Tragelements 31 und damit der Saugdüsen 30. Sollen hingegen Druckplatten an einen Formzylinder 13 übergeben und in einen Spannkanal des Formzylinders eingefädelt werden, so geben hingegen die Fixierbolzen 35 die schwimmende Lagerung des Tragelements 31 und damit der Saugdüsen 30 frei.Fixing pins 35 of a fixing device, which are axially displaceable in the direction of the arrows 36, cooperate with the ball rollers 32. The fixing bolts 35 penetrate the support member 31 and the cross member 33 and are guided in the cross member 33 associated guide members 37. In the presentation of the Fig. 5 give the fixing bolts 35, the floating bearing of the two suction nozzles 30 free, so that accordingly the support member 31 is tilted together with the suction nozzles 30 to some extent. In order to fix the support element 31 and thus to block the floating support of the suction nozzles 30, the fixing bolts 35 are opposite the in Fig. 5 shown moved downward position so that the fixing bolts 35 associated phases 38 engage in corresponding phases of the support member 31. Then, when printing plates 16 are to be picked up and transported, the fixing bolts 35 block the floating support of the support element 31 and thus the suction nozzles 30. If, on the other hand, pressure plates are transferred to a forme cylinder 13 and threaded into a clamping channel of the forme cylinder, the fixing bolts 35 on the other hand the floating support of the support member 31 and thus the suction nozzles 30 free.

Um das Einfädeln der Druckplatten in den Spannkanal eines Formzylinders zu unterstützen, kann dem gesamten Handhabungsorgan 28 eine nicht-dargestellte Vibrationseinrichtung zugeordnet sein, um dieselbe in Vibrationen zu versetzen.In order to assist the threading of the printing plates in the clamping channel of a forme cylinder, the entire handling member 28 may be associated with a vibration device, not shown, in order to set the same in vibration.

Anstelle einzelner Saugdüsen kann das als Saugeinrichtung ausgebildete Handhabungsorgan 28 auch als durchgehender Saugbalken ausgeführt sein. Ein Unterdruck im Bereich der Saugdüsen wird über Druckluftelemente 39 bereitgestellt.Instead of individual suction nozzles, the handling device 28 designed as a suction device can also be designed as a continuous suction bar. A negative pressure in the region of the suction nozzles is provided by means of compressed air elements 39.

Fig. 6 zeigt eine Seitenansicht auf eine Handhabungsvorrichtung 10 zwischen zwei Drucktürmen 40 und 41. Ein Ende der Handhabungsvorrichtung 10 ist dabei an einer Traverse 45 beweglich gelagert. Die Traverse 45 ist zwischen dem linken 40 und rechten Druckturm 41 linear in Richtung 44 (in Zeichenebene) beweglich gelagert. Hierdurch kann die Traverse 45 samt Handhabungsvorrichtung 10 seitlich aus den Drucktürmen herausgefahren werden. Hierdurch können bei herausgefahrener Handhabungsvorrichtung 10 die Druckeinheiten 11, die nun besser zugänglich sind, gewartet werden. Fig. 6 shows a side view of a handling device 10 between two printing towers 40 and 41. One end of the handling device 10 is movably mounted on a cross member 45. The traverse 45 is linearly mounted in the direction 44 between the left 40 and right printing tower 41 (in the drawing plane). As a result, the traverse 45 including handling device 10 can be moved laterally out of the printing towers. As a result, when the handling device 10 has moved out, the printing units 11, which are now better accessible, can be serviced.

Zusätzlich zu den bereits in Figur 2 beschrieben Schwenkachsen 23 bis 26 ist die Handhabungsvorrichtung 10 ebenfalls in Pfeilrichtung 43 verschwenkbar bzw. rotatorisch gelagert, so dass mit einer Handhabungsvorrichtung 10 die Druckeinheiten 11 des linken 40 und rechten Druckturmes 41 beladen und entladen werden können, siehe gestrichelt dargestellte Handhabungsvorrichtung rechts unten. Die Handhabungsvorrichtung 10 kann weiterhin entlang der Pfeilrichtung 42 obere und unter Druckeinheiten 11 des gleichen oder benachbarter Drucktürme 40 und 41 bedienen.In addition to those already in FIG. 2 described swiveling axes 23 to 26, the handling device 10 is also pivotally mounted in the direction of arrow 43 or rotatory, so that with a handling device 10, the printing units 11 of the left 40 and right printing tower 41 can be loaded and unloaded, see dashed lines shown handling device right below. The handling device 10 can continue to operate along the arrow direction 42 upper and under pressure units 11 of the same or adjacent towers 40 and 41.
