傳統中藥需要煎煮服用,非常麻煩,科學中藥使用濃縮造粒改良成藥粉,可以搭配開水服用,因此獲得廣泛歡迎。隨著科學中藥大量普及,包藥技術開始受到重視,無論是人力配置、操作時間,或藥粉均勻度與殘留量等,都可能形成工作的瓶頸。因此本研究與K公司合作開發直立式包藥技術,希望能解決上述問題,同時改善分包藥粉的均勻度。 本研究利用伺服控制技術達到均勻分包藥粉之目的,主要控制參數放在分藥及包藥兩個區塊。其中,分藥技術採用直立式藥罐,藉由伺服馬達推動罐內的活塞,可確保藥粉推升高度的一致性。分藥機構頂端設有360度旋轉的刮刀,可快速將藥粉送入漏斗,進行包藥。包藥技術結合熱封滾輪、電動夾爪,可以快速安靜的包裝藥粉,且長度可依重量而自動調整,有利於節省包裝紙的耗材費用。 研究過程中,發現藥粉量會有不均之現象,根據分析發現,主因為藥粉受到擠壓時,受力不平均,造成藥罐內藥粉上中下密度不同。本研究採用兩種改良方法,第一個方法在機構上進行調整,確保機構的平行度,同時調整伺服馬達的進料速度及改善定位精度,讓藥粉不會因為機械的誤差而導致不均的現象。第二個方法是在修正馬達推桿的上升量,並根據藥粉種類、黏性、顆粒大小,分析出最佳化的修正結果,透過程式,導入修正量,即可得出藥粉均勻化之結果。
Traditional Chinese medicine needs to be boiled before taking it, which is very troublesome. Scientific Chinese medicine uses concentration technology and is improved into a powder, which can be taken with boiling water, so it is widely welcomed. With the popularization of scientific traditional Chinese medicine, medicine packaging technology has begun to receive attention. At present, the main technical bottlenecks include manpower allocation, operation time, powder uniformity and residual amount, etc. For this reason, this study cooperates with K-company to develop the vertical drug packaging technology, hoping to solve the above problems and improve the uniformity of subpackaged drug powder. The main control technology in this study is divided into two blocks: drug distribution and drug packaging. Among them, the medicine dispensing technology uses a vertical medicine tank, and the piston in the tank is driven by the servo motor, which can ensure the consistency of the medicine powder pushing height. There is a 360-degree rotating scraper on the top of the drug distribution mechanism, which can quickly send the drug powder into the funnel for drug packaging. The medicine packaging technology combined with heating rollers and electric grippers can quickly and quietly pack medicine powder, and the length can be automatically adjusted according to the weight, which is beneficial to save the cost of packaging paper consumables. During the research process, it was found that the amount of medicine powder would be uneven. According to many experiments, it is found that the main reason is that when the powder is squeezed, the force is uneven, which causes the powder density in the medicine tank to be different. This study adopts two improved methods. The first method adjusts the mechanism to ensure the parallelism of the mechanism, and adjusts the feeding speed of the servo motor to reduce the mechanical error. The second method is to analyze the optimal correction result based on the type, viscosity, and particle size of the powder, and then import the correction amount through the program to obtain the homogenization result of the powder.
