Abstract
An optical inspection machine has a discharge chute provided for receiving fragile articles thrown from a high speed belt in the course of ejecting such articles. The chute has an 'S'-shaped bottom with the top of the 'S' under the trajectory of the ejected articles, the mid portion of the 'S' positioned to receive the falling articles at a minimum impact angle, and the bottom of the 'S' discharging the sliding articles after being significantly decelerated due to the variable slope of the 'S'-shaped chute bottom. The inspection machine has another 'S'-shaped chute for receiving articles from an infeed conveyor and transferring them to the high speed belt while minimizing deceleration.
