摘要如今，机械工业飞速发展，包装机械的种类也纷繁复杂，纸箱包装机械是包装机械的一个非常有代表性的分支，不仅可以减少了大量的人力物力，提高生产效率，而且使用纸箱包装机包装产品可减轻劳动强度，适应大规模生产的需要，并满足清洁卫生的要求，在箱子过大，物品过重的情况下，人力不能完成，这时候，机械生产起到了关键的作用。在生产大发展的背景下，为应对社会竞争，手工开箱，封箱，包物，已不能满足生产的需要。为此，需要研制出具有自动化、精度化、效率化自动包装机械的机械结构和控制系统，以解决超大纸箱的自动包装，物品的自动膜包这一问题。84919

本文讲述的是全自动封闭式超大型纸箱包装线控制系统设计。全自动指的是该包装机不仅整个工作过程是全自动的，而且可以适应一定尺寸范围的纸箱包装。封闭式指的是每个纸箱的拼接叠合处都采用胶带密封，要包装的物品也采用封闭式膜包，并且热收缩定型。超大型指的是该箱子最大尺寸满足1200*1200*750，基本可以满足很多产品的要求。本文包括研究背景、现状、意义和包装机的控制说明书。控制说明书就根据纸箱、物品包装的原理，进行了总体设计，确定了系统的设计方案，确定采用三菱PLC进行控制。形成了包括开箱、膜包、传送、封箱等在内的系统。然后针对各部分，对包装线进行了时间安排，对传送带的带速，电机的转速以及电机节拍的时间进行分析计算，并对气压缸进行了气力分析，之后对各控制器械进行选型。在对控制系统的具体设计中，有控制线路的设计，I/O接口的设计，I/O口的地址分配，梯形图，最后再对程序进行模拟仿真。

目前，纸箱包装机的控制系统已经完成，也通过软件对程序进行了模拟仿真，完全可以完成纸箱的包装，实现了全自动超大纸箱封闭式包装的目标，从而提高生产效率。

Abstract Today, rapid development of machinery industry, the types of packaging machinery is numerous and complicated, carton packaging machinery is packaging machinery of a very representative of the branches can not only reduce a lot of manpower and material resources, improve production efficiency, and carton packaging machine packaging products can reduce the labor intensity, to adapt to the needs of large-scale production, and meet the sanitary requirements, in the box is too big, heavy items, human can not be completed。 At this time, production machinery to the key role。 Under the background of the development of production, in order to cope with social competition, hand out of the box, box sealing and package objects, has been unable to meet production needs。 To this end, we need to develop a mechanical structure and control system with automation, precision and efficiency of automatic packaging machinery, in order to solve the problem of automatic packaging of large boxes, automatic packaging of articles。

This paper is about the design of the control system of the full automatic enclosed super large carton packaging line。 It is not only the whole working process of the packing machine is automatic, but also can be adapted to a certain size range of carton packaging。 Closed type refers to the splicing of each box is the use of adhesive tape seal, to the packaging of the goods are also using a closed membrane package, and heat shrink。 Super large refers to the size of the box to meet the 1200*1200*750, the basic can meet the requirements of many products。 This paper includes the research background, current situation, significance and control specifications of packaging machine。 According to the principle of the carton, the article packaging, the overall design, determine the system design, determine the use of MITSUBISHI PLC control。 Including the formation of the film out of the box, bag, transmission, sealing, system。 Then for each part, on packaging line time arrangement, of conveyor belt speed, motor speed and motor cycle time for analysis and calculation, and the strength analysis of pneumatic cylinder, after the control equipment selection。 In the specific design of the control system, the design of the control circuit, the design of the I/O interface, the address assignment of the I/O port, the ladder diagram, and the simulation of the program。
