Abstract
An apparatus for securing danger zones in a bale opening system. The apparatus includes a first beam transmitting/receiving device and a beam guide for guiding the first beam in a generally U-shaped course. A space between the legs of the U-shaped course accommodates conveyor belts on which bales are supported, the bale opener in any position along a path of travel thereof, a shuttle carriage in any position along a path of travel thereof and at least one part of a loading station. The shuttle carriage travels between a loading station where a bale is loaded on the carriage and a location on a conveyor belt where the carriage deposits the bale. The apparatus further has second and third beam transmitting/receiving devices for generating and detecting second and third beams each having a course connecting legs of the U-shaped course in a zone of the loading station. The second beam is more remote from the base of the U-shaped course of the first beam than the third beam. A switching arrangement selectively activates and deactivates the second and third beam transmitting/receiving devices.
