Device for separating a stack by layers, particularly a stack of long timbers or lumber

摘要

A device is disclosed for separating at least one elongated member or layer of members, particularly a layer of elongated lumber pieces, which comprises a shifting unit for shifting a top layer above the lumber pieces partly off the remainder of the stack. The shifting unit is positioned at one end of the stack and moves part of the shifted layer out over the opposited end of the stack. A propping unit is positioned at the opposite end of the stack and is movable up and under the overhanging part of the shifted layer and then across the top of the remainder of the stack to separate this layer from the remainder of the stack. Transfer arms are provided which can be moved into the space between the shifted and separated layer and the remainder of the stack to support the layer and transfer it away from the stack for further processing.
