Abstract: Fruit defects of interest in the production of prunes are identified based on characteristics of illumination reflected by the fruit. Various reflection characteristics can be used in this regard including near infrared reflectivity and polarization state of the reflected illumination. In one embodiment, the apparatus (10) of the present invention includes a transport system (12) for transporting fruit (14) through an inspection zone (16), a reflector type illumination system (18) for illuminating the fruit, a detector system (20) for detecting reflected illumination (21), a sorting system (22) for separating defective fruit from good fruit, and a control system (24) for controlling operation of the sorting system based on signals from the detector system and transport system. In another embodiment, a projector type illumination system (18') provides a uniform, high intensity strip of light that illuminates the fruit. The light projector is suitable for use in other machine vision applications.

Abstract: The sorting system provides a high degree of sorting accuracy even in high throughput sorting applications such as high speed wood chip sorting. In one embodiment, a sorting apparatus (10) includes a shaker (12) for distributing stock material, a spectrographic analyzer (14) for identifying unacceptable material in a product stream, an ejector (16) for diverting unacceptable material from the product stream, a three-zone sorting receptacle (18) and a recirculating system (20) for returning a selected portion of the sorter output for an additional pass by the analyzer (14) and ejector (16). The three-zone sorting receptacle (18) divides the product stream into an accept portion, a rejection portion, and an ambiguous portion including both acceptable product and unacceptable material. The ambiguous portion is re-sorted for improved accuracy at high throughput levels.

Abstract: The invention is directed to the field of stabilizing systems for stabilizing light-weight articles carried on conveyors for automated bulk processing equipment. In conventional stabilizing systems, light-weight articles become unstable after leaving the conveyor belt due to instability of the generated air flow leaving the belt, and further, the articles were inadequately illuminated, causing camera misdetection resulting in improper sorting. The present invention overcomes these drawbacks by improving air flow stability and article illumination. The invention includes a conveyor (16) for moving light-weight articles (17) from a first infeed end to a second discharge end where they are projected in air along a trajectory through an illumination station (28) and sorting station (30). An enclosed off-belt housing (80) is provided within which the light-weight articles are projected along a controlled trajectory to be processed by the optical inspection and sorting systems.

Abstract: A sorting system (10) propels a stream of randomly arranged PET and PVC articles (12, 14) through an inspection zone (20) including a first light polarizer/analyzer combination (24, 26), an article-detecting gap (G), and a second light polarizer/analyzer combination (28, 30). The first and second polarizer/analyzer combinations are oriented to extinguish normally incident light in the absence of articles in the inspection zone and are offset 45 degrees relative to each other such that at least one polarizer/analyzer combination detects a principal axis of birefringence of PET articles. The gap is employed to detect the presence of an article in the inspection zone. A video camera (22) includes first, second, and third CCD arrays (58, 60, 62) positioned to receive respective light arrays (48, 64, 50) from the first light polarizer/analyzer combination, the gap, and the second light polarizer/analyzer combination and to generate first, second, and third video signals representative of the light each receives. A video signal processor (68) processes the second video signal to identify the presence of multiple articles in the inspection zone, processes the first and third video signals to determine whether each of the multiple articles is made from PET, and selectively activates air ejectors (70) to separate the PET articles from the other articles.
