Printing unit of a printing machine with at least two relatively mutually positionally variable frame parts

摘要

Printing unit (01) of a printing press with at least two frame parts (13; 14) which can be changed in position relative to one another, wherein cooperating frame parts (13; 14) are set against each other in a first operating position and partly in a second operating position to form one of these frame parts (13; limited access space (17) are offset from each other, wherein an access control device (33) having a first part (46) and a second part (47) having a barrier, wherein the first part (46) of the fence on a first longitudinal side of the printing unit (01) obstructs a first access to the intermediate space (17) or this first access on the first longitudinal side of the printing unit (01) is at least lockable with this first part (46) of the barrier, the first part (46) and the second part (47) the barrier in each case starting from a no access to the intermediate space (17) obstructing the starting position common in the between the frame parts (13; 14) of the barrier, starting from a first position on the first longitudinal side of the printing unit (01), at which first position at least the first part (46) of the barrier the first Access to the intermediate space (17) is obstructed, through which the frame parts (13; 14) formed by the intermediate space (17) through to a second position on the second longitudinal side of the printing unit (01) is movable, which through the intermediate space (17) moved second part (47) of the barrier at its second position on the second longitudinal side of the printing unit (01) blocks a second access to the intermediate space (17) or this second access on the second longitudinal side of the printing unit (01) with this second part ( 47) of the barrier is at least lockable, wherein the first longitudinal side of the printing unit (01) whose drive side (S1) and the second longitudinal side of the printing unit (01) whose control page (S2), wherein on the control side (S2) an operating unit (37) is present, with which operating unit (37) a drive (36) is controllable, said drive (36) at least the first part (46) of the barrier starting from the non-access to the intermediate space (17) obstructing the starting position in a first access to the gap (17) on the drive side (S1) obstructing operating state moves.
