【摘要】：柔性集装袋广泛运用于运输业。随着全球化的进程，物流业高速发展，对柔性集装袋的需求不断增加。美国、日本等国由于人工成本高，生产柔性集装袋利润小，其物流业更倾向于从外国进口柔性集装袋，为我国生产柔性集装袋提供了良好的发展机会。我国生产柔性集装袋起步较晚，，主要采取手工生产的方式，生产成本高，效率较低。 本文对柔性集装袋自动生产设备的控制系统进行设计，使得自动缝纫两种不同规格的柔性集装袋成为可能。若自动生产设备稳定运行，其生产效率可达1个/min，能够有效降低人工成本，提高劳动生产率。因此，本文重点在于设计柔性集装袋自动生产设备的自动控制系统，以实现对该设备的合理控制。 首先，对柔性集装袋自动控制系统进行总体控制系统设计。根据设备的生产要求以及控制流程的设计，合理设计出整个设备的总体控制系统设计。其次，在整体控制方案确定的基础上，分析整个控制系统的设计难点即如何实现转运小车通讯和自动缝纫，通过设计上电模块解决转运小车与各个工位进行通讯的问题；通过对缝纫轨迹的设计和电机的控制设计，实现自动缝纫。再次，在解决了控制的难点后，完成硬件系统设计。根据自动生产设备的结构设计以及相关的控制要求，确定PLC的型号，I/O口地址分配，扩展模块的选型；同时完成硬件设备的选型及控制方案设计如伺服电机，步进电机，三相异步电机等。最后对整个自动生产设备进行软件系统设计，在分析整理了整个控制系统的控制逻辑后，进行软件编程设计。
[Abstract]:Flexible container bags are widely used in transportation industry. With the process of globalization and the rapid development of logistics industry, the demand for flexible container bags is increasing. Due to the high labor cost and low profit in producing flexible container bags, the logistics industry of the United States and Japan is more inclined to import flexible container bags from foreign countries, which provides a good development opportunity for the production of flexible container bags in China. The production of flexible container bags in China started late, mainly by manual production, with high production cost and low efficiency. In this paper, the control system of automatic production equipment for flexible container bag is designed, which makes it possible to sew two kinds of flexible container bags with different specifications. If the automatic production equipment runs stably, its production efficiency can reach 1 / min, which can effectively reduce labor cost and improve labor productivity. Therefore, the emphasis of this paper is to design the automatic control system of the flexible container bag automatic production equipment in order to realize the reasonable control of the equipment. First of all, the overall control system design of flexible container bag automatic control system is carried out. According to the production requirements of the equipment and the design of the control flow, the overall control system design of the whole equipment is designed reasonably. Secondly, on the basis of the determination of the overall control scheme, the design difficulties of the whole control system are analyzed, that is, how to realize the communication between the transfer trolley and the automatic sewing, and how to solve the communication problem between the transfer trolley and each work station through the design of the power-up module; Automatic sewing is realized by the design of sewing track and the control of motor. Thirdly, after solving the difficulty of control, the hardware system is designed. According to the structural design of automatic production equipment and related control requirements, the PLC model, I / O port address allocation, expansion module selection; At the same time, complete the selection of hardware equipment and control scheme design, such as servo motor, step motor, three-phase asynchronous motor. Finally, the software system design of the whole automatic production equipment is carried out. After analyzing the control logic of the whole control system, the software programming design is carried out.
