Abstract
A printing-plate dust removing apparatus includes a guide rail 12 provided in parallel with a plate cylinder 1; a slider 13 moving along the guide rail 12; a holder 18 supported by the slider 13; a moving member 19 supported by the holder 18, the moving member 19 having a plurality of dust removing blades 28; and a driving gear for shifting the moving member 19 intermittently. A driving shaft 38 of the driving gear is connected with a driven shaft 27 through coupling members 41 and 42. Interlocking claws 41A and 42A of the coupling members are set so that the coupling members are engaged with each other at a standby position of the dust removing blades. Also, the holder 119 and the slider 113 are connected with each other by wedge members 138 and 144 so that the wedge members are firmly engaged with each other by a clamping bolt 147 and a holder plate 140. A printing-plate dust removing system 205 includes the above printing-plate dust removing apparatus and a controller 231, in which the controller compares a presumed position which is now in recognition and an actual position based on a signal c input from a detecting sensor 242 for detecting the position of the slider 206 so tha…
