<P>PROBLEM TO BE SOLVED: To manufacture a safety facility for reducing unintentional interruption in a sheet-fed paper delivery device of a sheet-fed paper processing machine in operation acceptable by an operator when maintaining the access possibility of a stack chamber for performing handling operation. <P>SOLUTION: This safety device has a plurality of respective sensors for liftably arranging a stack of the delivery device inside the stack chamber, stacking sheet-fed paper on the stack by using a carrying system and arranged in the whole going in and out areas of the sheet-fed paper delivery device; and is constituted so that the sensors are associated to a mechanical control part for stopping the sheet-fed paper processing machine in unpermitted intrusion into the stack chamber, and the individual sensors can be cut off only for a time range for performing a work process in a state of intruding into the stack chamber without stopping the sheet-fed paper delivery device only for a limited time range when intruding into the stack chamber by an input facility. The safety device is provided with the sensors 10 for grasping the movement of the stack 4 of the delivery device or a pallet 3 for supporting the stack 4 of the delivery device in an area of the stack chamber. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
