Abstract: The problem of singulating oblong articles that are unloaded in an arbitrary orientation onto a conveyor has been solved in that the conveying trough is divided into a central, lower part and surrounding upwards-and-outwards extending parts, whereby the central part vibrates with a longitudinal amplitude that is higher than that of the upwards-and-outwards extending parts at the same frequency.

Abstract: The problem of singulating oblong articles (1a, 1b, 1c, 2a, 2b) that are unloaded in an arbitrary orientation onto a conveyor has been solved in that the conveying trough (4) is divided into a central, lower part (5) and surrounding upwards-and-outwards extending parts (6, 7), whereby the central part (5) vibrates with a longitudinal amplitude that is higher than that of the upwards-and-outwards extending parts (6, 7) at the same frequency.

Abstract: Apparatus for use to check potatoes or similar items, the apparatus including a feeding device for advancing the potatoes in a plurality of rows, a conveying device adapted to receive the rows of potatoes from the feeding device and advancing them while maintaining the row structure, at least one camera with associated image processor for recording and evaluating each individual potato on the conveying device and a sorting device controlled by the image processor, the sorting device being adapted to sort the potatoes. The conveying device includes a plurality of substantially horizontal rollers, the axes of rotation of the rollers extending parallel to the advance direction of the potatoes, the rollers being rotatably mounted in a support frame and connected with a first driving device for rotating the rollers. The rollers are each independently additionally displaceable in parallel forwards and backwards in a substantially straight line.
