ABSTRACT:
Articles are conveyed along a singulator conveyor system by being conveyed upwardly along an inclined first conveyor which is inclined at an angle of at least twenty-five degrees, so that any articles disposed atop other articles will fall off. The articles are discharged onto a second conveyor travelling horizontally at a linear speed at least twice that of the first conveyor in a direction substantially perpendicularly to a direction of travel of the first conveyor. The articles are then discharged from the second conveyor onto a third conveyor travelling generally horizontally at a linear speed at least twice that of the second conveyor in a direction substantially perpendicularly to the second conveyor. The articles are discharged from the third conveyor onto a slide which guides the articles downwardly onto a fourth conveyor which travels in the same direction as the third conveyor at the same speed as the third conveyor. The slide is transversely inclined toward an inner longitudinal edge of the fourth conveyor to guide articles downwardly toward that edge and into engagement with a vertical guide wall extending along that edge.
