Abstract
An apparatus for supporting the shaft journals of a printing cylinder, that can be dipped into a dye vat, of a rotary roller printing machine, preferably a Rotogravure Rotary Roller Printing Machine, on support rolls for the purpose of exchanging the printing cylinder. In order to be able to exchange the printing cylinder in a simple and fast manner, the support rolls are arranged on horizontally movable beams via which the support rolls can be shifted between the bearings of the printing cylinder and an extended position in which there is provided a device that lifts and inserts the printing cylinder.
Claims15
A printing group of a rotary roller printing machine having a printing group frame, comprising:
- a printing cylinder having a shaft journal;
- a support roll arranged on a generally horizontally moveable beam for supporting said shaft journal during an exchange of said printing cylinder, said beam guided on said printing group frame and having a drive mechanism by which said printing cylinder can be moved from a printing position to an extended position;
- and
- a device which lifts said printing cylinder from said beam when in said extended position and inserts a replacement printing cylinder for return thereof to said printing position through generally horizontal movement of said beam.
A printing group of a rotary roller printing machine having a printing group frame, comprising:
- a dye vat retained on a vat carrier that can be lifted and lowered in the printing group frame;
- a printing cylinder dipped into said dye vat and having a shaft journal;
- a generally horizontally moveable beam for supporting said shaft journal during an exchange of said printing cylinder, said beam guided on said printing group frame and engaged with said vat carrier only when said carrier is in its raised position;
- a drive mechanism coupled to said beam by which said printing cylinder can be moved from a printing position to an extended position, said vat carrier moving generally horizontally with said beam when engaged therewith in said raised position;
- and
- a device which lifts at least said printing cylinder from said beam when in said extended position and inserts a replacement printing cylinder for return thereof to said printing position through generally horizontal movement of said beam.
