US 9,486,993 B2 · Method and device for setting ink-conducting rotational bodies of a printing press

Abstract

Rotational bodies of a printing press with at least a first, a second and a third ink-conducting rotational body, which interact with each other in pairs, can be set in a thrown-on position. The second of the at least three rotational bodies can be set both against the first of the three rotational bodies and against the third of the three rotational bodies in order to form a two-sided thrown-on position. Tracking, coupled in a defined way, of the rotational axis of the second rotational body takes place at the same time as a radial positional change of the rotational axis of the first rotational body, by the superimposition of two movements along two non-congruent movement paths which run in a plane which is perpendicular with respect to the rotational axis. A device for setting rotational bodies of a printing press is also provided.

Method for setting rotational bodies of a printing press having at least a first, a second and a third ink-conducting rotational body (21;

22;
23) which interact in each case in pairs in a thrown-on position, and wherein the second of the at least three rotational bodies (22) is set both against the first of the three rotational bodies (21) and against the third of the three rotational bodies (23) in order to form a two-sided thrown-on position, characterised in that tracking, coupled in a defined way, of the rotational axis (R22) of the second rotational body (22) takes place at the same time as a radial positional change of the rotational axis (R21) of the first rotational body (21), by way of the superimposition of two movements along two non-congruent movement paths which run in a plane which is perpendicular with respect to the rotational axis (R22) of the second rotational body (22).

Device for setting rotational bodies of a printing press having, at least a first, a second and a third ink-conducting rotational body (21;

22;
23), which interact in each case in pairs in a thrown-on position, wherein the second of the at least three rotational bodies (22) is radially movably mounted in a one- or multi-piece frame (47) between the first and the third rotational body (21;
23) such that it can be selectively brought into a thrown-on position in which it is set against the first rotational body (21) and the third rotational body (23), or into a thrown-off position in which it is out of contact with at least one of the two other rotational bodies (21;
23), wherein for mounting of the second rotational body (22) a bearing arrangement (46) is provided at the front comprising two adjusting elements (49;
51) for the radial movement of the second rotational body (22) by way of superimposition of two non-congruent movements each having a radial movement component, characterised in that a forced two-sided tracking of the second rotational body (22) is provided, which comprises a coupling of a movement of the two adjusting elements (49;
51) to a radial movement of the first rotational body (21) in a defined way such that a radial movement of the first rotational body (21) over a travel greater than zero at the same time effects a forced tracking of the two adjusting elements (49;
51) positioning the second rotational body (22) each by a defined travel that is greater than zero.
