ABSTRACT:
A laned conveyor apparatus includes an infeed roller and an outfeed roller rotatably mounted to a frame in spaced apart relation for movably supporting a flexible product-carrying belt that forms a closed loop about the rollers to define a conveying region having a length and a width. A plurality of elastic separating bands are removably positioned around the rollers and the product-carrying belt and spaced apart at intervals along the width of the conveying region to form lanes along the length of the conveying region. The separating bands contact an outer surface of the product-carrying belt to form a frictional interface with the product-carrying belt that causes the separating bands to move in coordination with movement of the product-carrying belt. A guide mechanism mounted to the frame includes multiple guide features spaced apart at intervals along the width of the conveying region for guiding the separating bands so that the lanes are accurately and precisely positioned in relation to the frame. An adjustable tensioning device is provided for tensioning the separating bands across the conveying region to minimize slippage of the separating bands at the frictional interface. An infeed device is positioned to feed multiple streams of articles into the lanes. The frame is suitable for mounting an inspection and sorting system near the outfeed end of the conveyor apparatus for inspection and sorting of the articles as they are projected from the outfeed end of the conveyor apparatus. The rollers define effective pitch diameters of the product-carrying belt and the separating bands. The ratio of the effective pitch diameter of the separating bands to the effective pitch diameter of the product-carrying belt results in movement of the separating bands at a faster linear rate than the product-carrying belt, thereby causing an article that is inadvertently placed partly upon one of the separating bands and partly contacting the product-carrying belt to be urged or turned onto the product-carrying belt as the article is carried along the conveying region. Methods of segregating streams of articles are also disclosed.
