AUXILIARY DEVICES TO MOTORIZE AND AUTOMATE THE MANUAL FUNCTIONS OF PRINTING PRESSES

摘要

Auxiliary devices to motorize and automate the drives of the table supports (12) of the feed table (2) and reception table (4), using the transverse camshaft (40), fitted with a take-off sprocket (41), relayed by the idler sprocket (44), coupled to the electromagnetic clutch (43), to drive the cross-shaft (16), turning the worm gears (11) or by means of a geared motor (48), provided with an elastic coupling (50) driving a bevel gear with spindle (49), fitted in place of the bevel gear (14), fixed at the end of the worm gear (11). Means of control, connected to a control cluster (51), enabling automation by programmed sequential cycles of the operation of the feed table (2) and reception table (4). The control clusters (52) include the means of operation of the miniature geared motors connected to the spindles of the control handwheels (36) and (38) regulating the angular displacement of the ink duct roller and of the fountain roller respectively. The control cluster (54) comprises the means of displacement step by step of the motor of the printing press (1) enabling the rotation in either direction of its (3) printing cylinders.
