Optimal Design Of The Synchronous Tracking System In Pharmaceutical Filling Machine

With the development of the global pharmaceutical packaging machinery industry, filling machine have got more and more attention as an important part in the pharmaceutical industry. Filling machinery and equipment is in development stage in China, the domestic equipment manufacturers varies greatly. Product quality distance performance in lower product performance, with poor stability and reliability, the rough production, less pretty designs, most components of poor quality, short working life and large gap in order and control the level of automation, as well as accuracy and speed in filling with imported equipment. Especially there still is a big blank in high-speed filling machines.For this situation, this paper combined with the practical requirements of Shanghai East China Pharmaceutical Co., Ltd., based on the model of the KBG10 type filling machine to analyze the technical requirements and structural features. Then proposed a structural optimization of transformation and a more advanced overall improved control methods, to get a high-speed filling requirements.Firstly, the paper focused on the synchronous tracking device, analyzed the characteristics of the device, proposed the gear and cam mechanism that affect the filling speed and stability, study and analyze the stability and accuracy of the ball screw drive. According to the design parameters overall, select the right type of ball screw drive mechanism in synchronous tracking system, choose the right ball screw.Secondly, the paper performed mathematical calculations for simultaneous tracking system. Analyzed the motion state of working steps of the synchronous tracking system, established the model of the whole servo tracking filling machine. Then according to the requirements of the servo positioning module and the servo tracking system determine the working way of the servo motors and motion mode, establishe the tracking algorithm theory for the 12-pin block straight filling machine.Finally, simulate the synchronism tracking system. Establish the virtual prototype model of synchronous tracking system. Then on this base alalyze the dynamic response simulation of the transmission mechanism. The simulation results not only demonstrate that the dynamic analysis of the synchronous tracking system ball screw drive mechanism is correct. And further enhance the stability of the synchronous tracking system by studying the simulation results end the optimal design of the motion curve of the synchronous tracking system.
