【摘要】：随着消费要求的日渐增高，消费者对果蔬产品的安全、保鲜、外形包装等的要求越来越高，近年来对果蔬的包装日渐重视起来。本课题对果蔬自动包装机进行设计及开发，不仅符合杭州百乡缘农产品开发有限公司对农产品机械开发的要求，同时也是现今农产品包装机械的重点研究对象。本课题设计开发的果蔬自动包装机，机器完成果蔬送料、包装薄膜袋状成型、包装袋袋口封合及包装成品输出整个包装过程，包装机自动化程度高，各类包装参数都可通过人机交互界面进行设定，由总控制系统（PLC）配合伺服系统进行控制给予信号反馈使机构自动完成相应的包装动作。果蔬自动包装机的设计过程是：（1）根据包装要求、包装过程确定技术参数和包装机构，分析确定包装的工艺流程。根据对包装机外形美观、机构布局紧凑不松散、操作简易不复杂等要求，对机器整体进行合理布局。（2）根据工序要求以及机器运动与传递的关系设计机器的传动系统，确定传动比。（3）针对机构的作用，对相应执行机构进行选择或设计。其中，重点对果蔬自动包装机的制袋成型器和端封机构进行创新设计。（4）根据果蔬包装的非规则性，设计了果蔬自动包装机的控制系统。该系统以可编程逻辑控制器（PLC）为控制核心，通过变频器控制电机转速，实现各机构的速度匹配，完成包装的整个过程。PLC的应用，大大减少了包装机控制系统设计、安装、调试的工作量，并利用传感器实时调节，使包装机达到高自动化、机构高度同步、包装定位精准、包装效率高、包装质量好等要求。本课题研发的果蔬自动包装机，自动化程度高，，精度高、效率高、包装效果好，不仅能适应不同尺寸规格的果蔬包装，同时也能对其他领域如食品、医药、日用品等的产品进行包装，而且能满足现今消费者对果蔬产品的安全、保鲜、外形包装等日渐增长的需求。机器的研发不仅拥有广阔的市场、满足消费者的需求，同时对包装机械在果蔬领域进一步的发展有积极促进作用。
[Abstract]:With the increasing demand of consumption, consumers have higher and higher requirements for the safety, freshness, shape packaging of fruit and vegetable products. In recent years, more and more attention has been paid to the packaging of fruits and vegetables. The design and development of the automatic packaging machine for fruits and vegetables not only meet the requirements of Hangzhou Baixiang Agricultural Product Development Co., Ltd. At the same time, it is also the key research object of agricultural packaging machinery. The design and development of the automatic packaging machine for fruits and vegetables, the machine completed the delivery of fruit and vegetables, packaging film bag forming, packaging bag mouth sealing and packaging finished product output of the whole packaging process, packaging machine automation is high. All kinds of packaging parameters can be set by man-machine interaction interface, and the main control system (PLC) and servo system are used to control and give signal feedback so that the mechanism can automatically complete the packaging action. The design process of the automatic packaging machine for fruits and vegetables is: according to the packaging requirements, the packaging process determines the technical parameters and the packaging mechanism, and analyzes and determines the technological process of the packaging. According to the appearance of the packaging machine, the appearance of the packaging machine is beautiful. The mechanism layout is compact and not loose, the operation is simple and not complicated, the reasonable layout of the whole machine. 2) according to the requirements of the working procedure and the relation between the machine movement and the transmission, the transmission system of the machine is designed. Determine the transmission ratio. 3) according to the role of the mechanism, the corresponding executive mechanism is selected or designed. Emphasis is placed on the innovative design of the bag making and end sealing mechanism of the automatic fruit and vegetable packaging machine) according to the irregularity of fruit and vegetable packaging. The control system of the automatic packaging machine for fruits and vegetables is designed. The PLC controller is used as the control core and the speed of the motor is controlled by frequency converter to realize the speed matching of each mechanism. The application of PLC in the whole process of packaging greatly reduces the workload of the design, installation and debugging of the control system of the packaging machine, and the real-time adjustment of the sensor makes the packaging machine achieve high automation. High synchronization mechanism, accurate packaging positioning, high packaging efficiency, good packaging quality and other requirements. The automatic packaging machine for fruits and vegetables developed in this paper has high degree of automation, high precision, high efficiency and good packaging effect. It can not only adapt to the packaging of fruits and vegetables of different sizes, but also can be used in other fields such as food and medicine. Daily necessities and other products packaging, and can meet today's consumers on the safety of fruit and vegetable products, fresh, packaging and other growing needs. The development of machinery not only has a broad market. To meet the needs of consumers and to promote the further development of packaging machinery in the field of fruits and vegetables.
