Study And Manufacture On Muti-Computer-Controlling System And Research On Work Reliability In The Compound Danshen Dropping Pill Automatic Packaging Machine

Tianjin Tasly Pharmaceutical Co., Ltd. is a large Chinese pharmaceutical enterprise combining scientific research, production and market exploration. Its great product, Compound Danshen dropping pill, has got the permission of INS form FDA and became the first traditional Chinese medicine getting into the Western market. It has special treat effect to the heart disease. The products supply has fallen short of demand, so it is very necessary to raise packaging productivity. Under such condition, Tianjin University together with Tasly makes the research and product of the automatic packaging line of Compound Danshen dropping pill.In this paper, multi-computer-controlling system is stressed after the general mechanical structure has been briefly introduced.First, main controller—PLC is the center of this controlling system. Its constitution and principle are talked as well as the function and design of its interfaces.Second, the application of Industrial PC and Intouch software are discussed. The function and advanced characteristics of Intouch are analyzed.Third, Man-Machine Interface—industrial touching screen has key meaning in this controlling system. Op0erating board is simplified greatly and the showing contents are richer because of its use.Then, the technical difficulties and new technology in the whole equipment's debugging are summed up in addition to the realization of the multi-computer-controlling system. The paper also discuss the research of work reliability.The equipment discussed in this paper is very practical. It has already brought great benefit to user. Practice shows that the target has been realized.
