  • Securing a hazardous area in the regin surrounding the automatic loading of reels on a reel changer
    Patent number: 8339260
    Abstract: A hazardous area in the region surrounding a reel transport of a reel changer is secured. A contactless protective device is located at the access boundaries of the region. This protective device can be deactivated for feeding and/or removing a known object and comprises an evaluation unit. The protective device is configured as a light curtain that is comprised of a plurality of light beams that run in parallel to each other. The evaluation unit includes an assembly for detecting the sequence of the interruption of the light beams during the feeding and/or the removal of an object. Based on the detected sequence of interruption of the light beams, a known object, that is permitted to access the hazardous area, is detected. The protective device is deactivated in this situation. Securing the hazardous area further includes the provision of a second contactless protective device that is permanently active.
