Beskyttelsesanordning til automatisk produktionsudstyr

摘要

Method and device at industrial production which is carried out by automatic equipment (11) at a protected working station (16) to supervise stages which are performed at a very low velocity at which the accidental risk is small for a person who moves in the working area (25) of the equipment, whereby said equipment at actuation of an existing protection device (10) carries through the operation going on if it occurs at a safe low velocity in response to a velocity detector (100) which gives a secure stop if the process is terminated or if the velocity increases past a stated limit value.
