Abstract (en)
[origin: EP0888829A2] The grader has a feed conveyor (15); a sorting drum (1); a stacker (16,30); and a control system which measures the quality and/or dimensions of each item (17) e.g. plank on the conveyor and rotates and indexes the drum so that each slot (3) collects items within specific limits. When a slot contains enough items for one layer (6) of a stack (7) the slot is indexed to the stacker (16,30) and a radial ejector (20) pushes the planks onto the stacker. The drum is driven by an endless toothed band (10) which wraps around rollers (11) and part of the drum periphery. Several alternative arrangements are described some of which have more than one drum, conveyor and/or stacker.
