Suction device for retaining and/or transporting objects of different formats

A suction device for retaining and/or transporting objects, comprising:

• a main supporting body (2);
• at least one operating plate (3) mounted on the main supporting body (2), the operating plate (3) having an operating surface (6), and in which a plurality of suction holes (7) is made;
• and
• suction means in fluid connection with said plurality of suction holes (7) for sucking air through them;
• characterised in that:
• the operating plate (3) is removably associated with the main supporting body (2);
• the main supporting body (2) has at least one first connecting face (4);
• and
• the operating plate (3) has a second connecting face (5) placed on the opposite side to the operating surface (6) and which is coupled to the first connecting face (4) when the operating plate (3) is associated with the main supporting body (2);
• and in that it comprises one or more magnets (13) and one or more ferromagnetic bodies (14), each ferromagnetic body (14) being magnetically coupled to one or more magnets (13) when the operating plate (3) is associated with the main supporting body (2) for keeping the operating plate (3) fastened to the main supporting body (2), each magnet (13) and the ferromagnetic body (14) magnetically coupled to it being constrained respectively one to the operating plate (3), the other to the main supporting body (2).
