Abstract
A destacking/feeding system separates individual articles such as flat container blanks or trays nested in a stack. The destacking and feeding system comprises at least two pairs of opposed endless feed conveyor belts having respective vertical runs. The feed belts are spaced apart to grip opposite sides of the articles to feed them downwardly along a path to a second pair of belts or wheels which travel at a second, higher speed. The feed belts feed the stack of nested trays to the second, higher speed belts, which accelerate the lowermost articles and propel them downstream at the second speed. At the lower end of the second, higher speed conveyor, the articles are released and fall sequentially by gravity onto a waiting conveyor.
