Embodiment Construction

[0032] Such as figure 1 As shown, the present invention relates to an optical device of the type having a feed mechanism comprising a feed hopper assembly 2 and a chute 4 for conveying a stream of items to be sorted through an imaging zone 6 to a sorting zone 8 . Line scan camera 10 generates image data from an imaging field that is communicated to computer 12 coupled to graphical user interface 14 . Computer 12 processes the image data to identify items to be removed in the product stream and so instructs ejector array 16 to discharge air pulses at the product stream to deflect selected items from the product stream to discharge hopper 18 . The product remaining in the product stream continues into the receiving hopper 20 . This way of ejecting inferior products from a product stream is well known in the food processing industry. Line scan cameras can be visible or infrared, ultraviolet, x-ray, monochrome or multicolor.

Abstract

Sorting apparatus comprises a feed system for delivering a stream of articles in free flight to a sorting zone. Ejectors at the sorting zone are selectively activated to eject articles from the stream. A camera is disposed at an imaging zone upstream of the sorting zone to generate image data to be processed by a computer to identify articles to be ejected at the sorting zone according to one or more sorting criteria. The computer instructs the ejectors on the basis of the processed data. The computer is also coupled to a graphical user interface to display an image of the product stream at the imaging zone, and show the areas of intersection with the product stream of activated ejectors. The ejectors are normally operable to discharge a fluid such as a gas or air, in pulses, and the areas of intersection with the product stream are those directly intersected by the ejector fluid. Provision can be made for adjusting ejection parameters to move the boundaries of these areas of intersection.

Description

technical field [0001] The present invention relates to optical sorting machines, especially for sorting bulk food such as grains, rice, nuts, beans, fruits and vegetables. Examples of such devices are described in the specifications of International Patent No. WO98 / 018574 and European Patent No. 0 838 274, the disclosures of which are incorporated herein by reference. In this type of sorting machine, the stream of particles to be sorted is conveyed in free flight to a sorting area where it is about to be Removed items are ejected. The throughput required in such machines is usually determined by the throughput of processing plants at other sites. Typically, however, the required throughput is high and measured in tons per hour. [0002] Reference is also made to our International Patent Application entitled "Defect Browser For Sorting Machines" based on UK Application No: 0912390.2 filed today, the disclosure of which is hereby incorporated by reference.
