| At present,some large TCM hospitals already have automated equipment for dispensing,transporting and packaging TCM decoction pieces,but its shortcomings are more obvious,such as the accuracy is not up to the requirements,the supply of TCM is difficult,the scope of TCM is small,etc,so the existing automation The equipment cannot fully meet the needs of large,shared Chinese pharmacies.At the same time,most Chinese pharmacies in China still manually adjust Chinese herbal medicine pieces.The biggest disadvantage of this method is slow efficiency and high labor cost,which cannot meet actual needs and cannot be promoted.This subject researched and investigated the needs of Chinese pharmacies,the characteristics of Chinese medicine,and the advantages and disadvantages of existing automation products and equipment.Combined with the basic knowledge of mechanical theory,an automatic delivery system was designed and trial-produced.The system can complete bulk Chinese medicine particles.Compared with traditional Chinese pharmacies,the system can greatly save the entire dispensing time and improve the degree of automation and efficiency.First,complete the overall scheme design and technical requirements of the automated Chinese pharmacy delivery system according to actual needs and characteristics of Chinese medicine.It also explained the necessity of layout analysis from the aspects of traditional Chinese medicine types and dispensing efficiency;discussed the tipping bucket conveying layout plan,determined the layout of using a single-layer integrated medicine box and a single intermediate conveying mechanism;combined the characteristics of pneumatic conveying to carry out the layout of each device Showcase of the program.Then it introduces the improved tipping bucket conveying mechanism based on the traditional conveyor,and determines the size,shape of each part and the selection of the transmission part;using ANSYS to carry out the finite element and modal analysis of the conveying mechanism to ensure the reliability of the mechanism Performance;conduct transportation experiments and analysis to ensure smooth operation and maximize transportation efficiency.Then carried out the structural design and experiment of the pneumatic conveying system.The pneumatic conveying type was selected according to the parameters of the Chinese herbal medicine;the gas separator suitable for the Chinese herbal medicine was designed;the conveying pipeline and the fan were selected according to the actual working conditions;the pneumatic conveying capacity and the medicine output experiment were done to ensure The delivery is smooth and complete;at the same time,other major institutions are introduced and experimentally studied.Finally,according to the structure design and simulation experiment results,the tipping bucket conveying mechanism,pneumatic conveying device,intermediate conveying mechanism prototype,integrated medicine box support and cleaning device were trial-produced,and then their functions were tested.The improved and optimized institutions and equipment can achieve the expected functions.There are 89 figures,13 tables and 92 references in this thesis. |
