【摘要】：隨著生活水平的提高和經(jīng)濟(jì)發(fā)展的加快，藥房自動(dòng)化也有了長(zhǎng)足的發(fā)展。中藥房已開(kāi)始改變傳統(tǒng)的手工抓藥模式，逐漸出現(xiàn)了機(jī)械化設(shè)備代替部分手工勞動(dòng)。中藥飲片發(fā)藥機(jī)設(shè)計(jì)是國(guó)內(nèi)外藥房機(jī)械開(kāi)發(fā)的第一次嘗試。傳統(tǒng)中醫(yī)藥取藥模式是藥劑師根據(jù)處方信息人工抓取藥物，其典型缺點(diǎn)是速度慢、找藥效率低、衛(wèi)生條件較差、人工勞動(dòng)強(qiáng)度大、稱(chēng)量精度低等，，嚴(yán)重阻礙了我國(guó)中醫(yī)藥的發(fā)展和中醫(yī)藥房的規(guī)�；�、規(guī)范化。目前中藥自動(dòng)化機(jī)械種類(lèi)非常少，自動(dòng)化程度較低，體積龐大，所能處理的中藥種類(lèi)較少以及稱(chēng)量技術(shù)不完善，所以中藥機(jī)械有很大的發(fā)展空間。 本課題總結(jié)了目前存在的各種中藥機(jī)構(gòu)的優(yōu)點(diǎn)和不足，借鑒了已有的比較成熟的藥品機(jī)械結(jié)構(gòu)，設(shè)計(jì)出了第一臺(tái)自動(dòng)化程度高、出藥效率高的中藥機(jī)械，解決了中藥不規(guī)則引起的出藥不均勻、尋找目標(biāo)藥品速度慢、稱(chēng)量速度慢等問(wèn)題。設(shè)計(jì)了一套中藥飲片發(fā)藥機(jī)結(jié)構(gòu)圖紙，包括回轉(zhuǎn)柜結(jié)構(gòu)設(shè)計(jì)、行走機(jī)構(gòu)結(jié)構(gòu)設(shè)計(jì)和中藥藥箱設(shè)計(jì)�；剞D(zhuǎn)柜容納中藥藥箱并具有在Y向?qū)ぶ返墓δ�，結(jié)構(gòu)主要包括底座、天軸、地軸以及載荷鏈等結(jié)構(gòu)。行走機(jī)構(gòu)主要包括動(dòng)力箱、導(dǎo)軌以及電子秤等結(jié)構(gòu)，具有在X方向?qū)ぶ返墓δ堋?運(yùn)用等效單自由度系統(tǒng)理論，通過(guò)實(shí)驗(yàn)手段測(cè)定了不同材料以及不同壓力下結(jié)合面的特征參數(shù)，為結(jié)構(gòu)的有限元分析提供結(jié)合面數(shù)據(jù)。利用ANSYS軟件對(duì)回轉(zhuǎn)柜結(jié)構(gòu)進(jìn)行了靜力學(xué)分析和模態(tài)分析。通過(guò)分析指出了回轉(zhuǎn)柜結(jié)構(gòu)的最大應(yīng)力點(diǎn)和最大變形位置。通過(guò)模態(tài)分析得到了結(jié)構(gòu)的前六階固有頻率以及相應(yīng)的振型，為結(jié)構(gòu)優(yōu)化提供依據(jù)。在ANSYS有限元分析的基礎(chǔ)上，運(yùn)用單位體積能量法識(shí)別出回轉(zhuǎn)柜結(jié)構(gòu)中存在的薄弱環(huán)節(jié)，并提出解決方法。 對(duì)載荷鏈進(jìn)行了固有頻率計(jì)算，得出了在不同預(yù)緊力作用下對(duì)應(yīng)的固有頻率以及振型。并且對(duì)載荷鏈進(jìn)行了強(qiáng)迫振動(dòng)分析，總結(jié)出了預(yù)緊力對(duì)載荷鏈強(qiáng)迫振動(dòng)的影響，為施加預(yù)緊力提供指導(dǎo)。 設(shè)計(jì)并加工了一套中藥藥箱實(shí)驗(yàn)裝置，測(cè)試了中藥藥箱的出藥情況。測(cè)定不同螺桿種類(lèi)和不同轉(zhuǎn)速對(duì)出藥速度和出藥流暢性的影響，并提出修改方案。對(duì)動(dòng)態(tài)稱(chēng)重系統(tǒng)進(jìn)行了研究，為動(dòng)態(tài)稱(chēng)重控制系統(tǒng)設(shè)計(jì)提供了參考。
[Abstract]:With the improvement of living standard and the acceleration of economic development, pharmacy automation has made great progress. Chinese pharmacy has begun to change the traditional manual medicine mode, and gradually mechanized equipment to replace some manual labor. The design of dispenser is the first attempt of mechanical development of pharmacy at home and abroad. The traditional Chinese medicine drug taking mode is the pharmacist according to the prescription information to grasp the medicine manually, its typical shortcoming is slow, the drug searching efficiency is low, the hygiene condition is poor, the artificial labor intensity is big, the weighing precision is low, etc. Seriously hindered the development of Chinese medicine and Chinese medicine room scale, standardization. At present, there are very few kinds of automatic machinery of traditional Chinese medicine, low degree of automation, huge volume, fewer kinds of traditional Chinese medicine that can be handled and imperfection of weighing technology, so Chinese medicine machinery has a great space for development. This paper summarizes the advantages and disadvantages of various traditional Chinese medicine institutions, and designs the first Chinese medicine machinery with high automation and high drug delivery efficiency. The problems of uneven drug delivery caused by irregular delivery of traditional Chinese medicine, slow speed of searching for target drugs and slow weighing speed were solved. This paper designs a set of drawing of dispenser of traditional Chinese medicine, including structure design of rotating cabinet, structure design of walking mechanism and design of traditional Chinese medicine box. The revolving cabinet contains the traditional Chinese medicine box and has the function of addressing in Y direction. The structure mainly includes the base, the celestial axis, the earth axis and the load chain and so on. The walking mechanism includes power box, guide rail and electronic scale, and has the function of addressing in X direction. By using the theory of equivalent single-degree-of-freedom system, the characteristic parameters of the bonding surface under different materials and different pressures are measured by experimental means, which provides the data of the bonding plane for the finite element analysis of the structure. The static analysis and modal analysis of the structure of rotary cabinet are carried out by using ANSYS software. Through analysis, the maximum stress point and the maximum deformation position of the rotating cabinet structure are pointed out. The first six natural frequencies and corresponding modes of the structure are obtained by modal analysis, which provides the basis for structural optimization. On the basis of ANSYS finite element analysis, the unit volume energy method is used to identify the weak links in the structure of the rotary cabinet, and the solutions are put forward. The natural frequencies of the load chain are calculated and the corresponding natural frequencies and modes are obtained under different pretightening forces. The effect of preload force on the forced vibration of load chain is summarized, which provides guidance for the application of preload force. A set of experimental device of traditional Chinese medicine box was designed and processed, and the dispensing condition of traditional Chinese medicine box was tested. The effects of different screw types and rotational speeds on the speed and fluency of the discharge were measured, and a modified scheme was put forward. The dynamic weighing system is studied, which provides a reference for the design of dynamic weighing control system.
