Board Edger System, Hardwood Sawmill, McDonough ValueMax

This linear edger system was built for a US hardwood sawmill that saws very high value hardwood lumber. They wanted to be able to have a good view of both sides of the board, utilize the accuracy of a linear edger and allow the operator to adjust the optimized decision before the board was sawn. To meet these goals the system uses digital linescan cameras in the entry rollcases to present the operator with a high definition image of both the top and bottom of the board when the board arrives at the "grading/loading hook". We also placed the operator in a cab downstream of the scanners that provides him a view of the flitches as they pass into the edger (the sawbox is immediately behind the cab). If the operator should choose to manually rip a board based on visual defects the board will stop in front of the cab and the optimizer solution will be displayed using overhead laser lines. Lasers/sawlines are then adjustable individually to allow the operator very fine control over the location of any one saw.

This combination of technologies has proven very successful in maximizing the recovery of value for this customer utilizing the mechanical simplicity of a linear edger system.
