Description
Auswechselbarer Formzylinder für Rotationsdrucker. Den Gegenstand der Erfindung bildet eiii den Satz tragender, auswechselbarer Formzylinder für Rotationsdrucker, der vermittels einer besonderen Einrichtung auf der Zylinderachse leicht lösbar befestigt werden kann, ohne daß die beim Druckvorgang radial auftretenden Kräfte- den zentrischen Lauf des Formzylinders beeinträchtigen.Interchangeable form cylinder for rotary printers. The subject the invention forms eiii the set of supporting, interchangeable forme cylinders for rotary printers, which is easily detachable by means of a special device on the cylinder axis can be attached without the radial forces occurring during the printing process affect the centric running of the forme cylinder.
'Der Gegenstand der Erfindung ist in den Abb. i bis 3 der Zeichnung in einer Ausführungsform in zwei verschiedenen Stellungen veranschaulicht, und zwar steillen dar: Abb. i eine Ansicht des Rotationsdruckers in Arbeitsstellung mit festgespanntem Formzylinder, Abb. 2 den Rotationsdrucker ohne FormzyIinder mit ausgelösten Spannbuchsen und Abb. 3 den herausgenommenen Formzylinder.The object of the invention is illustrated in Figs. 1 to 3 of the drawing in one embodiment in two different positions, namely in a rigid manner: released clamping bushes and Fig. 3 the removed forme cylinder.
Die Zylinderbohrungenb und bl des Formzylindersa sind größer als der Durchmesser der Zylinderachsed und sind mit Schlitzen/ versehen, welche das radiale Eintreten der Zylinderachsed in den Formzylindera ermöglichen.The cylinder boresb and bl of the forme cylindera are larger than that Diameter of the cylinder axis and are provided with slots /, which the radial Allow entry of the cylinder axis into the forme cylinder.
Beim Verschieben der auf der Achsea verschiebbar angeordnet-en Spannbuchsen eel nach außen treten diese in die Bohrungenb und bl des Formzylinders a und verhindern somit jede radiale Bewegung des Formzylinders. Durch geeignete Mttel wird ein selbsttätiges Verschieben der Spannbuchsene und el verhindert. Um das Eintreten der Spannbuchsen e, el- in die Zylinderbohrungen b und bl zu erleichtem, sind diese Zylinderbohrungenb und bl durch kreisrunde, mit einem Schlitz versehenee Einsatzstückee abgeschlossen, die mit dem Formzylinder fest verschraubt sind. Die Größe der Schlitze in den Stücken c entspricht dem Durchmesser der Achse d.When the clamping bushes eel, which are arranged displaceably on the axis a, are displaced outwards, they enter the bores b and b1 of the forme cylinder a and thus prevent any radial movement of the forme cylinder. An automatic shifting of the clamping bushing and el is prevented by suitable means. In order to facilitate the entry of the clamping bushes e, el- into the cylinder bores b and bl, these cylinder bores b and bl are closed off by circular insert pieces provided with a slot, which are screwed tightly to the forme cylinder. The size of the slots in the pieces c corresponds to the diameter of the axis d.
Beim Herausnehmen des Formzylinders a werden die beiden Spannbuchsen e und el in achsialer Richtung nach innen zu verschoben und geben damit den Forrnzylinder frei. Er kann nun von der Zylinderachse d entfernt werden, ohne daß diese und die darauf befestigten Teile, beeinflußt werden.When the forme cylinder a is removed, the two clamping bushes e and el are shifted inward in the axial direction, thus releasing the forrn cylinder. It can now be removed from the cylinder axis d without this and the parts attached to it being affected.
Durch Wahl eines geeigneten Verhältnisses des Zylinderachsendurchmessers zum Spannbuchsendurchmesser können Formzylinder- in Anwendung gebracht werden, bei denen fast die ganze Zylinderoberfläche als Druckfläche ausgenutzt werden kann.By choosing a suitable ratio of the cylinder axis diameter Forme cylinder can be used for the clamping bush diameter which almost the entire cylinder surface can be used as a printing surface.
