Sheet processing machine with cooling roller and inspection device as well as a sheet printing machine with simultaneous double printing unit, curing device and cooling device

A sheet-fed printing machine (01), wherein a transport path is provided for a transport of sheets (02) assigned to the sheet-fed printing machine (01), the sheet-fed printing machine (01) comprising:

• at least one application device (200) configured as a simultaneous double printing unit (200) with at least one application point (201) arranged along the transport path for applying material to the sheets (02), the simultaneous double printing unit (200) including at least first and second transfer cylinders (204) arranged along the transport path provided for the transport of sheets (02) for applying material concurrently to a same sheet (02), the first transfer cylinder 204 cooperating with multiple first forme cylinders (202) that each provide a different respective material to the first transfer cylinder (204) and the second transfer cylinder 204 cooperating with multiple second forme cylinders (202) that each provide a different respective material to the second transfer cylinder (204);
• a curing device (300), which comprises at least one LED UV radiation source (302), being arranged along the transport path, downstream from the at least one application point (201), the curing device (300) comprising a first curing unit (321) for drying a first side of the sheets (02) and a second curing unit (322) for drying a second side of the sheets (02) located opposite the first side, the transport path extending between the first curing unit (321) and the second curing unit (322);
• at least one cooling device (301) assigned to the curing device (300), and comprising at least one cooling element (303), respectively, that includes a line system through which cooling liquid can flow for transport of the cooling liquid, the transport path including a chain gripper system (304) transferring the sheets (02) to the at least one cooling device (301);
• wherein:
• at least one curing section of the transport path is defined by at least one operating zone of the curing unit (300), and the at least one LED UV radiation source (302) of the curing device (300) is aligned with a portion of the chain gripper system (304) associated with the at least one curing section of the transport path;
• a cooling section of the transport path is defined by at least one operating zone of the at least one cooling element (303);
• and
• any cooling section of the transport path is arranged downstream from any curing section of the transport path;
• the sheet-fed printing machine (01) further comprises at least one inspection device (400), which is arranged so as to be aligned with a region of the transport path that is downstream from the at least one cooling element (303);
• and
• the at least one inspection device (400) comprises a first inspection unit (401), the first inspection unit (401) comprising at least one first sensor device for detecting electromagnetic radiation in a visible-light range of an electromagnetic spectrum, and the first inspection unit (401) comprising at least one second sensor device for detecting electromagnetic radiation in at least a portion of an infrared region of the electromagnetic spectrum.
