ABSTRACT:
An automatic stick laying apparatus designed to successively position spacing sticks on stacks of lumber for spacing the lumber in stacked tiers. In a preferred embodiment the stick laying apparatus includes a fixed frame designed for positioning over the lumber, a spacing stick accumulator mounted on the fixed frame and a carriage assembly attached to the fixed frame in vertically movable relationship. The accumulator includes a pair of spaced, horizontal accumulator chains fitted with accumulator chain cleats located above spaced drop gates for receiving and deploying the spacing sticks in a continuous loop. The carriage assembly is fitted with parallel chain channels supporting horizontal positioner chains having positioner chain cleats for receiving the spacing sticks from the accumulator through the drop gates and positioning the spacing sticks over respective layers of lumber. Multiple pivoting diverter assemblies are spaced between the chain channels for sequentially displacing selected spacing sticks on or from the positioner chain cleats to facilitate depositing these spacing sticks in selectively spaced relationship on the underlying tiers of stacked lumber by selective limited or unlimited advancement of the positioner chains. The automatic stick laying apparatus may be connected to a programmable controller for automatic operation.
