-
摘要: 【目的】将整根毛竹锯切成特定长度规格竹段,是竹材初加工中最重要的工序,现有的毛竹锯切设备大多存在诸如机械化水平低、安全隐患大、人工成本高等问题,亟需设计制造出先进的锯切设备以推动竹材初加工产业的健康发展。【方法】采用图像采集技术和可视化分析技术,设计出1台基于可编程控制器(PLC)控制的毛竹智能避节定长锯切设备。【结果】在现有设备的基础功能上,增加了任意长度规格竹段的灵活定长(误差范围为±30 mm)、竹节的智能识别与规避、竹段的自动卸料与分选等功能,特别是达到了所得竹段两端30 mm内均不存在竹节的技术要求。对毛竹智能避节定长锯切设备进行了样机试验,定段准确率、避节准确率、分选准确率均达到100%,平均加工效率约达到27.37 m·min-1,工作效率相比人工提升35%,劳动力成本降低80%以上。【结论】该设备的研发符合现阶段的生产需要,大幅提高了毛竹定长锯切设备的机械化、自动化水平,同时提高了加工精度和原料利用率,为后续建立1条连续化、智能化的竹材初加工生产线提供了条件。

Abstract: 【Objective】 Cutting the whole bamboo with saw into a specific length specification is the most important process in bamboo primary processing. Most of the existing bamboo sawing equipment has problems such as low mechanization level,big potential safety risks and high labor cost,so it is urgent to design and manufacture advanced sawing equipment to promote the healthy development of bamboo primary processing industry. 【Method】 Using the technology of image acquisition and visualization analysis,based on programmable logic controller (PLC),an intelligent sawing device for Moso bamboo was designed. 【Result】 In addition to the basic functions of the existing equipment,the flexible length determination (error range is ±30 mm),intelligent identification and avoidance of bamboo nodes,automatic unloading and sorting of bamboo segments were added,especially to achieve the technical requirements that there are no bamboo nodes within 30 mm at both ends of the obtained bamboo segments. Prototype tests were carried out for Moso bamboo on intelligent cutting equipment with fixed length with node avoidance. The accuracy of section setting,node avoidance and sorting reached 100%,the average processing efficiency reached about 27.37 m·min-1,the work efficiency was raised by 35% and the labor cost was reduced by more than 80% compared with those in the manual cutting. 【Conclusion】 The research and development of the equipment meet the current production needs,they have greatly improved the mechanization and automation level of the fixed-length saw cutting equipment,and improved the processing accuracy and raw material utilization rate at the same time,which provides conditions for the subsequent establishment of a production line for continuous and intelligent bamboo primary processing. -
