DEVICE FOR INSTALLATION OF CYLINDER TO SUPPORTS, REFERENCE NODE AND CONTROL METHOD OF PUNCHER ENGAGING Russian patent published in 2009 - IPC B41F13/30 

FIELD: mechanical engineering.

SUBSTANCE: device includes bearing unit, moving in line tower lengthwise perpendicular to pivot pin of cylinder of setting direction (S). Supports are implemented as reference node in the form of mounted as complete unit modular unit. Reference node includes journal bearing, two interacting reference nodes, different from side bed support. To support it is fast fixed relative to stand one of reference elements. Reference elements provide movement of bearing unit. Proposed printing unit contains at least three cylinders interacting to each other as printing apparatus. At least three of two cylinders are installed in line poles with ability of movement lengthwise positioning direction (S). Each of mobile cylinders is installed in provided only for this cylinder reference node. Positioning direction (S) forms with connecting plane E; E'; E" angle (β), equal maximum 15°. Additionally length of bearing facility of line pole is less than diametre of joined to it cylinder of printing apparatus. For each of reference elements it is provided actuating mechanism. Actuating mechanism impacts by force (F) in the direction of printed contact area on bearing unit. According to provided methods at first it is transferred blanket cylinder into position of switched-on impression and release master cylinder, by means of restriction cancellation of positioning behavior. On master cylinder it is influenced by appointed effort and is supplied to blanket cylinder. Influence by effort is implemented by means of feeding into actuating mechanism of working medium of appointed pressure. Then it is implemented restriction of positioning direction (S) of master cylinder in the direction of printed contact zone. Restriction and cancellation of positioning direction restriction is implemented by means of reduction and correspondingly release of support. In one option of method blanket cylinder can be installed motionlessly relative to bed.

EFFECT: providing of simplicity of mounting and service of printing unit.
