Abstract:
A suction adherence conveying device for printing plates comprising:suction cups which are provided so as to be able to approach and move away from a surface of a printing plate or an interleaf sheet accommodated in a magazine; a suction section which communicates with the suction cups through communicating paths and sucks in air from the suction cups, and due to the suction section sucking in air from the suction cups, the printing plate or the interleaf sheet is vacuum-suction-adhered and removed from the magazine in this state one at a time; and a pressure sensor which is set in communication with the communication paths, and detects that a degree of vacuum at the time of suction-adhesion by the suction cups is greater than or equal to a first degree of vacuum set to correspond to a case in which the interleaf sheet is suction-adhered, and detects that the degree of vacuum at the time of suction-adhesion by the suction cups is greater than or equal to a second degree of vacuum which is set to correspond to a case in which the printing plate is suction-adhered and which is higher than the first degree of vacuum.
