Abstract
An apparatus for placing spacer sticks between layers of lumber is disclosed. The present invention includes an overheads feed system for distributing spacer sticks to a plurality of stick placement modules. Each stick placement module has a plurality of stick placement arms which are articulated to move in three dimensions. After the arms grasp a spacer stick, the deviation of the arms from their normal orientations are used to gauge the suitability of the spacer stick and then to reject the spacer stick if the quality of the spacer stick does not meet specifications. Also, the apparatus of the present invention is modular and can be retrofitted to existing lumber stacking machines.
