Claims17
A printing machine having at least one operating location and at least one hazardous area, the printing machine comprising:
- a sensor system scanning the at least one hazardous area;
- a display electrically connected to said sensor system, said display:
- disposed at the at least one operating location;
- and
- displaying the at least one hazardous area scanned by said sensor system;
- and
- a control device for operating the printing machine, said control device:
- electrically connected to said sensor system and to said display;
- and
- programmed to count through a given time window and to permit start-up of the printing machine only after said control device receives an acknowledgement within said given time window that the at least one hazardous area has been examined.
In a printing machine having a hazardous area and an operating location, a safety system comprising:
- a sensor system scanning the hazardous area;
- a display electrically connected to said sensor system, said display:
- disposed at the operating location of the printing machine;
- and
- displaying the hazardous area scanned by said sensor system;
- and
- a control device:
- electrically connected to said sensor system and to said display;
- and
- programmed to count through a given time window and to permit start-up of the printing machine only after said control device receives an acknowledgement within said given time window that the at least one hazardous area has been examined.
A method for securing at least one hazardous area of a printing machine, which comprises:
- scanning a hazardous area of the printing machine with a sensor system;
- placing a display at an operating location of the printing machine;
- defining a time window;
- displaying at least the hazardous area scanned by the sensor system on the display;
- and
- controlling operation of the printing machine by permitting start-up of the printing machine only after an acknowledgement is received within the time window indicating that the hazardous area has been examined.
