摘要： The procedure includes observation of each grain by optic-electronic devices and consists of an initial stage during which several values, representing color signals, are extracted and read and are then processed by a computer to reduce all the signals to two numbers only, defining a pair of coordinates on a plane where the colorimetric characteristics of the grains are represented, and of a second stage in which each grain is automatically classified within an electronic grid, related to the above plane, wherein an operator has already assigned the squares for classes of unacceptable grains. The machine includes an analog-to-digital converter able to convert the analog signals received from the observation devices into binary form, two adapter circuits, a computer and a memory for controlling, sampling and analog-numerical conversion of the color signals, also for storing all samples obtained, as well as for executing the above first and second stages of the procedure.

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： A valve device is disclosed for controlling the delivery of gas from a pressurised source suitable for use in a pneumatic ejector in particle sorting apparatus. It uses a diaphragm as a valve member disposed over an output port from a chamber which is in substantially continuous communication with a source of gas or air under pressure. Both sides of the diaphragm are exposed to pressurised gas or air in the chamber. For this reason, and because the diaphragm itself engages the output port to close it, when the input pressure is applied there is a differential pressure which elastically deforms the diaphragm to close the output port. The diaphragm has a piezoelectric element, and the valve device includes an electric circuit operable to selectively activate the piezoelectric element and withdraw the valve member from the output port to admit pressurised gas or air thereinto.

摘要： A method of sorting comprising viewing objects to be sorted to determine whether any of them, at least in part, reflects, transmits or emits light in a predetermined part or parts of the spectrum to an undesired extent or in an undesired ratio, the objects being viewed while passing across a background which is also viewed and whose reflectance, transmission or emission of light in the said part or parts of the spectrum has a predetermined relationship with that of the average of the objects, effecting relative separation between any undesired objects which have been viewed and the remaining objects, periodically effecting an examination as to whether the said predetermined relationship exists and, if it does not, effecting an adjustment of the reflectance, transmission or emission of light by the background and/or adjusting the incident radiation onto the objects in the said part or parts of the spectrum so as to tend to restore the said predetermined relationship.

摘要： A chute for inspection and sorting apparatus is disclosed. It comprises two sections; a first, upper section (6) and a lower, grooved section (2). The first section has a smooth, normally polished surface which allows product pieces thereon to move laterally as well as downwards. In the lower section (2) product pieces are restricted in their lateral movement by the grooves (12) and move into alignment with the grooves before being discharged into the inspection zone (22) of the apparatus. If the apparatus is for inspection only, then the product pieces continue to a collection receptacle. If the apparatus is for sorting, then an ejector (26) is included which acts in response to signals from the inspection station to eject selected pieces from the product stream. Those are deflected into a reject receptacle (28) while the remainder proceed into the collection receptacle (24).

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： In an apparatus for sorting material into desired and undesired pieces or portions according to their optical characteristics, comprising a background, and a viewing means for viewing the material against the background; a method for removing debris from the background is proposed which comprises providing a jet of air or water which is moved relative to and across the background, and directed towards the background so as to remove debris and thereby clean the background. The jet is positioned out of the field of view of the viewing means so that debris removal can take place without interruption of the sorting process. A magnetic type air-cylinder, in which exhaust gas is fed back as the debris-removing air-jet, is preferably used.
