With wooden strips, wood production of finished plate with wood plates produced fairly, favored by many manufacturers, and not only cost savings, but also increased the efficiency of wood, there is good compliance with environmental standards. In the dwindling timber resources, many countries have adopted the use of puzzle pieces come together to form the whole timber wood panels. World War I developed a hydraulic drive and pneumatic transport for the development puzzle laid the foundation, after almost a century of development, the development of hydraulic drive is already quite mature, laid a solid foundation for the development of puzzle . Tension between supply and demand in the timber when a new wood processing equipment developed, with social development, peoples growing demand for wood, puzzle machine has great prospects for development. Hydraulic and pneumatic transport its excellent modern puzzle transmission power still the main hydraulic transmission, hydraulic system design and PLC program is to puzzle the most important in the design process. Based on the puzzle Hydraulic and workflow works analyzed finalizing the control scheme, the PLC control system design based on a hydraulic system that allows easy and simple puzzle. key words:Jointing machine; The hydraulic system; Control system; Pneumatic technology; Woodworking machinery 目 录 1.拼板机概述 1 1.1 拼板机的简介 1 1.1.1 拼板机产生背景 1 1.1.2 拼板机的种类 1 1.1.3 拼板机的发展现状 1 1.2拼板机各系统技术发展现状 2 1.2.1拼板机组成部分及各部分工序 2 1.2.2 气压传动技术 2 1.2.3
