A safety device for automated processing equipment which is disposed in combination with a linear actuator to prevent operator injury. The safety device includes a base plate and a spherical element engaging the base plate to effect relative displacement of structural elements having at least one spring element projecting downwardly from the base plate, the base plate defining an aperture therein having a peripheral edge, and the at least one of the spring element including a ramped surface defining a lead angle relative to a horizontal plane, and
- a spherical element coupled to the end of the actuation shaft and engaging the peripheral edge of the aperture in a coupled operating mode, and disengaging the peripheral edge of the aperture when transitioning from the coupled operating mode to a safe operating mode.
