Reel changer having a securing means for a safety area

A reel changer of a printing press comprising:

• at least first and second spaced end face side frames which comprise vertical supporting frame parts for the reel changer of the printing press and which side frames are spaced apart across a width of the reel changer and which are adapted to be able to support any ones of switchboxes and side boxes which may be arranged directly on the frame parts;
• a secured area which extends at least on one of a receiving and a discharge side of the reel changer and which has a width at least across the first and second end face side frames, the secured area being substantially fully enclosed, on one side, by the reel changer and on other sides by at least one of adjacent units and mechanical blocking devices, the secured area including a receiving and discharge area of the reel changer and an inner loading loop of the reel changer;
• a device for protecting the secured area;
• at least one sensor-monitored access point to the secured area and located in one of the other sides, the at least one sensor-monitored access point being adapted to afford an operational entry through the secured area by operators of the reel changer and into which operators of the reel changer can enter into the secured area only by moving through the at least one access point;
• and
• a frame outer alignment which continues an exterior side of the side frame on the loading side perpendicular to an axis of the reel changer, the secured area extending, on the loading side of the reel changer, beyond the frame outer alignment, the sensor-monitored access point into the secured area and which is provided on the loading side being arranged on the frame outer alignment which is distant from the reel changer and spaced laterally therefrom.
