APPARATUS FOR REMOVING DUST ON PLATE SURFACE OF PRINTING PRESS AND SYSTEM FOR REMOVING DUST ON PLATE SURFACE

摘要

An apparatus for removing dust on a plate surface comprises guide rails (12) provided in parallel to a plate cylinder (1), a slider (13) adapted for movement along the guide rails, a holder (18) supported by the slider, a moving body (19) supported by the holder and provided with a plurality of dust removing blades (28), and a drive device (31) for intermittently moving the moving body (19). A driving shaft (38) and a driven shaft (27) of the drive device are coupled to each other through coupling members (41, 42). Engaging jaws 41A of the coupling members are set such that the coupling members engage with each other when the dust removing blades are at a standby position. In addition, a holder (119) and a slider (112) are engaged with each other by means of wedge-shaped members (138, 144) which in turn are firmly engaged with and joined to each other by means of fastening bolts (147) and a holder plate (140). Furthermore, a system (205) for removing dust on a plate surface comprises the above-mentioned apparatus for removing dust on a plate surface and a control device (231) which compares an assumed position under recognition and an actually measured position with each other and make the both positions agree with each other on the basis of a signal c from a detection sensor (242) which detects a position of the slider (206). In addition, a control device (309) causes a moving body (208) (dust removing belt 210) to move and further the slide (206) to move only when data indicating that dust removing blades (211) are at a standby position is input into the control device (309) from a blade position detecting device (308).
