20140284255 | SORTING AND INSPECTION APPARATUS AND METHOD WITH DETERMINATION OF PRODUCT VELOCITY - A sorting and inspection apparatus comprising a feed system for delivering a product stream sequentially through an imaging zone and a sorting zone, at least one tight source for illuminating a product at the imaging zone, at least one optical sensor and detector circuit for viewing at least a portion of the illuminated product at the imaging zone, for collecting viewed data, for determining a condition of that at least portion of the illuminated product from the viewed data and then for outputting a signal dependent upon the determined condition of that at least portion of the illuminated product, and at least one ejector for ejecting product at the sorting zone dependent upon the output signal. The imaging zone comprises at least two sensor zones, sequentially arranged one after another in a direction of the product stream. The data collected from the at least two sensor zones is temporally delayed between an earlier one of the sensor zones and a subsequent sensor zone, with the temporal delay being set at a time that would match a sensor output for the said earlier one of the sensor zones with a sensor output for the said subsequent sensor zone for a hypothetical product travelling through the viewing zone at a fixed, predetermined velocity. The apparatus additionally determines the velocity of each product that passes through the sensor zones. The determined velocity, or its difference from the predetermined velocity, used in a determination of a shortened but non-clipped sector of each sensor zone from which to use collected data for basing its defect determination. | 09-25-2014 |
20130113918 | MULTI-CHROMATIC IMAGING SYSTEM AND METHOD - An imaging system for and method of imaging product in a product flow (F), the system comprising: an illumination unit for illuminating product in the product flow with illumination at first and second, different wavelengths or ranges of different wavelengths; a detector unit ( | 05-09-2013 |

20120171338 | MEASUREMENT OF A QUALITY OF GRANULAR PRODUCT IN CONTINUOUS FLOW - In apparatus for measuring the quality of a granular product in continuous flow, the product is allowed to move along a channel having a window set in the channel boundary contacted by the moving product. An optical system monitors product in the channel. A light source illuminates product in the channel through the window, and a sensor receives light reflected from the product through the window in at least two wavelength ranges. A processor receives signals from the sensor representative of the quantity of reflected light received in the respective wavelengths, and compares the respective signals to generate a measurement of the product quality. The window will normally be disposed in the underside of the channel, with the channel set at an angle of at least 45° to the horizontal to allow product to move there along under gravity, and against the window. | 07-05-2012 |
