Design of online log-core veneer lathe system for wood products

To change current status of veneer peeling process in wood enterprises, improve processing automation level and widen the scope of perspective and enhance enterprise competitiveness, the general design scheme of the online veneer lathe system for wood products was put forward by analyzing software/hardware and working mode of veneer lathe system. Based on the principle of integrated manufacturing system, the characteristics and new veneer formula of new log-core veneer lathe were analyzed, and a new mathematical model between the motor speed and the position of the driving roll-carriage was established. An auto-controlled system of new type of log-core veneer and its program, which was based on PLC and transducer, were developed according to these researches. And theoretical foundation and guidance for designing the veneer lathe system online were provided. The results show that processing scope of veneer is 0.3-3.7 mm, wood utilization is above 95%, linear velocity of veneer peeling process is 27 m/min. error of veneer thickness is below 0.03 mm .The machine can meet the wood production demand by experiments.
