Abstract

1,212,120. Sorting ore photo-electrically SPHERE INVESTMENTS Ltd. Dec.31, 1968, No.61888/68. Heading G1A. Relates to a system for memorizing the size and position of ore fragments passing through a photo-electric inspection station for synchronized operation of a down stream sorting device. As the ore moves along a conveyer belt, it is scanned by a photo-electric device to produce a reflectance signal which is analyzed to determine various parameters such as lighter or darker than predetermined levels or changes from light to dark within a predetermined time. The signals produced are fed to eight modules of which one is seized when a rock is detected and, ignoring other rocks looks for the rock that seized it at appropriate points in each scan. The module integrates the signals corresponding to its rock until, when it detects the rock no more, it compares preselected integrated signals in a preselected manner to decide whether the rock is acceptable or not. Twenty air blast nozzles are arranged across a sorting zone at the end of the belt and associated with each nozzle is a shift register. If a module decides a rock should be rejected, it determines, from pulses synchronized with the scanning, which of the nozzles the rock will pass and sets a number of stages in the corresponding shift register equal to the number of scans on which the rock was detected. The set stages are shifted through the registers by pulses from a belt tacho-generator so that they actuate the appropriate nozzles as the reject rock passes. As soon as the module has made its decision and, if necessary, set the shift registers it is reset to lock on to another rock when required.
