ABSTRACT:
A system is disclosed for controlling the discharge of articles from a steel belt conveyor. When articles are placed on the belt at the loading station, the belt is magnetized at a high intensity in a very small area which has a predetermined relationship, longitudinally of the belt, to the position of the article on the belt. The magnetized spot is also positioned transversely of the belt in accordance with the station where the article is to be discharged. At each discharge station there is an arrangement in the form of a plow and means to move the plow to and from the path of articles carried on the belt so as to deflect the articles from the belt. The plow operating mechanism has an electronic control which includes a Hall-effect transducer positioned adjacent the bottom surface of the belt and relatively positioned transversely of the belt along the path of the magnetized spots for that station. Hence, when an article is placed on the belt and the magnetized spot is produced corresponding to a particular unloading station. The article will be carried to that station and unloaded. The high intensity magnetization is produced by an electromagnet extending transversely from the bottom surface of the belt, and direct current is supplied to the electromagnet coil from a condenser circuit. The current can be caused to flow in either direction through the coil so as to produce a magnetized zone or spot of either north or south polarity. The magnetized zone or spot is surrounded by a ring of the opposite polarity but of insufficient intensity to energize the Hall-effect control unit. The number of discharge stations may be increased by producing two or more magnetized spots for various of the discharge stations.
