Research Design and Manufacture of Automatic Edging and Trimming System for Wood Board from Wagon in Sawing Line Using PLC Control System

The optimization of the processing stages in the sawmill line occupies a strategic position in processing wood products from raw materials (logs). The main objectives of this paper are to propose a design and manufacture an automatic edging and trimming (AET) system for a wood board to synchronize with the sawing line using programmable logic controller (PLC) system. To verify the design of integration, 20 different board samples were used to evaluate the effectiveness of the manufactured system. The results indicated that the AET system meets the basic requirements in cutting the edge waste out of the board and improving rate of wood recovery. Therefore, the idea of the AET system displays merits further research and may be applicable to future sawmills
