Abstract:
Optoelectric safety system for a machine that operates with at least some mechanically dangerous operating processes, which comprises:a system which protects a free entrance or access opening in the machine's protective housing or protective cage at all times during operation, including:an approximately vertical column at either side of the entrance or access opening, each column with at least one of a transmitter and receiver for an approximately vertical safety light barrier in the form of a multi-beam protective field covering an area;a reflection light scanner on the machine frame above and adjacent the floor at the front of the machine in the vicinity of the entrance or access opening, which emits a scanning beam covering a horizontal or inclined area with specifiable at least one of inclination (.alpha.) and geometry, which generates an inner permanent protective field and an outer dynamic protective field, outside of the vertical light barrier and towards an operator.
