Title: Light barrier safety device for machine tools - has intersecting groups of light beams
Inventor: BEER WOLFGANG
IPC: F16P3/14
Filed: 1973-08-27
Abstract: The light barrier for e.g., a metal press consists of selenium cells on to which light beams are directed. The beams are divided into groups. Within each group the beams are parallel to one another, but the different groups are arranged at an angle to one another. It is thus possible to eliminate the barrier effect of individual groups of beams so that only the required area round the workpiece is protected. With earlier devices of this kind, the whole barrier had to be switched off or on. It is prefd. that there should be two groups of beams at right angles and that these should be laser beams. Light barrier pref. consists of a semiconductor laser, of gallium, arsenic substrate.
