【摘要】：草帘编织机是以稻草秸秆为加工原料,通过机械缝纫技术从而将稻草秸秆加工制作成草帘、草袋等草编制品的机械设备。自上世纪90年代出现提出,发展较为缓慢,目前仍处于半自动阶段,可实现编织过程的机械化,但尚需人工进行铺草。人工铺草用工多、工作量大、工作环境恶劣、工作效率低、铺草不均匀。而且草帘编织一般在水稻收获后到且入冬之前,大约持续三到四个月时间,而草帘编织地区相对集中,在当前农村劳动力大量涌入城市的背景下,在编织季节易出现招工难、用工荒的现象,工人操作水平也难以保证,影响了草帘的编织数量与质量。所以发展自动化程度更高、智能化程度更高的草帘编织机有重要的研究意义与推广价值。自动铺草机实现铺草过程是通过设计气动控制系统运用神经网络的检测归纳输出信号控制气缸的前进后退,从而达到控制机械结构的运动过程,有效完成智能铺草的过程。人工神经网络结合气动原件还有传感器构成整体的自动控制铺草系统,神经网络的可以通过训练学习,根据训练学习的结果及传感器传回的信息控制电磁阀的开闭,进而控制气缸的伸缩,达到自动铺草的目的。解决传统草帘编织机铺草厚度不均匀的问题。将神经网络与原有铺草程序结合到自动草帘编织的铺草系统中,实现自动铺草的过程,随着劳动力用工成本的逐年上升,企业生产效率却没有随之增长,自动铺草控制系统能够解放劳动力提高生产效率,同时有力的解决市场需求和工厂生产不足之间的矛盾。综述了草帘编织机总体发展历程及编草、铺草部分的发展现状,同时对发现的问题进行了分析。即现在市面上的草帘编织机的机械化和自动化程度还很差,提出了自动草帘编织机在未来编草行业的重要地位。
[Abstract]:Straw curtain knitting machine is a kind of mechanical equipment, which takes straw as raw material and makes straw into straw curtain, straw bag and other straw products by mechanical sewing technology. Since its emergence in the 1990s, it has developed slowly and is still in the semi-automatic stage, which can realize the mechanization of the knitting process, but it still needs to be spread by hand. Manual grass-laying work, heavy workload, poor working environment, low efficiency, uneven spread of grass. In addition, straw curtain weaving usually lasts for three to four months after rice harvest and before winter. However, grass curtain weaving areas are relatively concentrated. In the context of the current influx of rural labor forces into cities, it is easy to find jobs in the weaving season. The phenomenon of labor shortage, workers' operation level is also difficult to ensure, affected the quantity and quality of grass curtain weaving. So it is of great significance and value to develop straw curtain weaving machine with higher degree of automation and intelligence. The automatic grass laying machine realizes the grass laying process by designing the pneumatic control system and using the neural network detection inductive output signal to control the advance and backward of the cylinder so as to control the movement process of the mechanical structure and effectively complete the process of intelligent grass laying. The artificial neural network combined with the pneumatic original and the sensor constitute the whole automatic control grass laying system. The neural network can control the opening and closing of the solenoid valve according to the result of the training study and the information returned by the sensor. And then control the expansion of the cylinder to achieve the purpose of automatic grass laying. To solve the problem of uneven laying thickness of traditional straw curtain weaving machine. The neural network is combined with the original grass laying program to realize the automatic grass laying process. With the increase of labor cost year by year, the production efficiency of enterprises does not increase. The automatic grass laying control system can liberate the labor force and improve the production efficiency, at the same time, it can solve the contradiction between the market demand and the insufficient production in the factory. This paper summarizes the general development course of straw curtain weaving machine and the present situation of grass weaving and spreading part, and analyzes the problems found. That is to say, the mechanization and automation of the straw curtain knitting machine on the market is still very poor, and the important position of the automatic straw curtain knitting machine in the future grass weaving industry is put forward.
