摘要： Sorting apparatus has a conveyor belt or equivalent mechanism for moving particles at a speed sufficient to generate a stream of particles in air, which particles can be graded such that unacceptable material can be removed. The grading or sorting is conducted by a primary scanning system for analyzing light reflected from particles in the stream in a plurality of wavelength ranges. Ejectors for removing particles from the stream are disposed downstream of the scanning system, and are instructed in response to signals received from the scanning system. An auxiliary scanning system is also included to establish the presence of material in the stream, and in the event that a void is detected in a given region, then the analysis of that region by the primary scanning system and any corresponding activation of the ejectors is inhibited.

摘要： Sorting apparatus has a conveyor belt or equivalent mechanism for moving particles at a speed sufficient to generate a stream of particles in air, which particles can be graded such that selected material can be removed. The grading or sorting is conducted by a primary scanning system for analysing light reflected from particles in the stream in a plurality of wavelength ranges. Ejectors for removing particles from the stream are disposed downstream of the scanning system, and are instructed in response to signals received from the scanning system. An auxiliary scanning system is also included to establish the presence of material in the stream, and in the event that a void is detected in a given region, then the analysis of that region by the primary scanning system and any corresponding activation of the ejectors is inhibited. If the auxiliary scanning system operates on the basis of light transmitted in the infra-red wavelength, then the scanning system can differentiate between a situation in which it is receiving light reflected from a product piece in a product stream, and light transmitted across the path of the product stream in the absence of a product piece therefrom. By this means, the monitoring of light received from the path of the product stream in the infra-red range can be used to perform all functions.

摘要： A sorting machine for sorting ground nuts affected by a mould which produces aflatoxin comprises detectors for detecting infra-red (or red) and green light respectively reflected from a ground nut being viewed. The infra-red detector produces a first signal indicative of the amount of mould carried by the ground nut. The green detector produces a signal indicative of the extent to which the ground nut is mechanically damaged, and also produces a gating signal. A comparison signal is derived from these first and second signals and is passed by way of a gate and a level detector to an ejector. The gating signal controls the operation of the gate in dependence upon the extent to which the ground nut being viewed is mechanically damaged, so that the ejector is actuated by comparison signals of a predetermined level only when the extent to which the ground nut is mechanically damaged does not exceed a predetermined value.

摘要： A sorting machine comprising a chute for moving a plurality of objects sequentially past a plurality of viewing zones which are spaced apart in the direction of movement of the objects so that the moving objects pass to an object separation zone in which relative separation is effected between desired and undesired objects. Light sources are on opposite sides of the moving object for directing beams of light to the viewing zones. Viewing devices view the objects passing through the viewing zones from opposite sides, respectively, of the moving objects. A discriminator, controlled by the output from the viewing devices, determines whether objects which have been so viewed are desired or undesired. An object separator controlled by the discriminator effects relative separation at the object separation zone between the desired and undesired objects. The viewing devices and light sources are so arranged that at least most of the light which is reflected by an object so as to be directed into a viewing device is derived from a light source disposed on the same side of the moving objects as the respective viewing devices.

摘要： An apparatus for sorting or otherwise treating objects, wherein the apparatus includes an endless belt which is in contact with a guide by means of which the endless belt is given a curved portion. At least one path between the guide and the curved portion of the belt is provided for the passage of objects therethrough. The path has an inlet portion arranged to receive objects which have traveled thereto along a trajectory which has a substantial horizontal component at the inlet portion, and the path has a vertically disposed outlet portion. A feeder is provided for feeding the objects to the inlet portion of the path. The belt is driven so that objects passing into the path through the inlet portion thereof are centrifugally forced against the belt and carried thereby to the respective outlet portions. The objects are sorted or otherwise treated as they fall under gravity from the outlet portion.
