【摘要】：药型端面的包覆可以提高药型的燃烧渐增性。传统的药型端面包覆采用多人现场人工包覆,人工包覆方式生产人员劳动强度大,人为因素的不确定性也会造成包覆质量参差不齐,包覆生产间存在大量易燃药型且生产间为粉尘环境,如果发生爆炸,过多的生产人员会因逃脱不及时造成重大生产事故。为了解决这个问题,本课题在改进胶黏剂的基础上提出了实现自动化包覆,通过制定合适的自动包覆方案,设计相应的包覆装置,减少在线生产人员,提高生产安全性。药型包覆过程即为阻燃片的粘接过程,本文首先根据现场生产条件和粘接工艺过程分析实现自动包覆的可行性,制定自动包覆工艺和多工位的药型端面包覆方案。然后根据确定的多工位包覆方案设计相应的多工位药型端面包覆装置,其中包括装置的机械机构、动力来源和控制系统的设计。机械装置设计过程中围绕组合涂胶和阻燃片贴合两个关键问题设计了药型端面立式涂胶装置、阻燃片卧式涂胶装置、阻燃片贴合装置和多工位药型输送装置。本文设计的多工位包覆装置采用气压驱动,根据机械装置运动要求确定了气动元件和气动系统回路。在电气控制系统的设计中,确定了控制器、控制方式和端口分配以及控制程序。最后对研制的多工位药型包覆装置进行调试并分析解决了输送气缸偶发的抖动问题,并对包覆后的药型进行质量抽检。此外,为了保证自动包覆的安全,以使用环境作为重点考虑因素,分析了多工位包覆装置电气和非电气方面的防护措施。
[Abstract]:The coating of the end surface of the medicine type can improve the burning increasing of the medicine type. The traditional coating of the end surface of the medicine type adopts multi-person artificial coating on the spot, and the labor intensity of the production personnel is high in the way of artificial coating. The uncertainty of human factors will also lead to uneven coating quality, there are a large number of flammable agents in the coating production and the production environment is dust, if explosion occurs. In order to solve this problem, this paper puts forward the realization of automatic coating on the basis of the improvement of adhesive, and through the formulation of appropriate automatic coating scheme. The corresponding coating device is designed to reduce the number of on-line production personnel and improve the safety of production. The coating process is the bonding process of flame-retardant flame-retardant sheets. In this paper, firstly, the feasibility of automatic coating is analyzed according to the field production conditions and bonding process. The automatic coating process and the multi-station end coating scheme are made. Then the corresponding multi-station end coating device is designed according to the determined multi-station coating scheme including the mechanical mechanism of the device. The design of power source and control system. In the process of mechanical design, the vertical coating device and horizontal coating device for flame-retardant sheet were designed around two key problems: combination coating and flame-retardant laminate bonding. Flame-retardant laminating device and multi-station delivery device. The multi-station coating device designed in this paper is driven by air pressure. The pneumatic components and the pneumatic system loop are determined according to the motion requirements of the mechanical device. In the design of the electrical control system, the controller is determined. The control mode, port distribution and control program. Finally, the development of the multi-station explosive coating device was debugged and the jitter of the conveying cylinder was analyzed and solved. In addition, in order to ensure the safety of automatic coating, the protective measures in electrical and non-electrical aspects of multi-station coating device are analyzed.
