Control System Design Of GZP Series High Speed Tablet Press Machine

Along with economic development and people’s emphasis on health degreeenhances unceasingly, the state of the deepening of the reform, the quality andquantity requirements of has obviously improved, these led to the rapid developmentof the pharmaceutical industry, to promote the prosperity of the pharmaceuticalequipment industry. For various reasons, the development level of Chinesepharmaceutical equipment technology is still in the very great degree in imitation,improvement, and composite stage, not reached the level of innovation, or more thanthe world of similar products, the current development of China’s pharmaceuticalequipment with foreign pharmaceutical equipment level less than10to20years.Pharmaceutical GMP (Good Manufacturing Practice), an important part of thehardware, since China compulsory certification of GMP system was introduced, andaround the pharmaceutical factory to speed up the pace of the technologicaltransformation in succession, combined with the requirements of GMP for equipmentresearch and development. Due to the limited domestic pharmaceutical factoryinvestment capacity and the production varieties, to achieve "one machine can"became the medicine factory in front of a big requirement, improve the automationlevel of equipment is an important factor.After investigation and analysis of the drug market, found that the tablet is a kindof pharmaceutical dosage forms, therefore tablet press is the most importantpharmaceutical equipment. Into large-scale pharmaceutical industry development, tocontrol the quality of performance and the requirement of increasing the equipment isstable, reliable, and more and more enterprises begin to consider the choose and buyhigh speed tablet press machine, tablet press and analysis, design of control system isof great importance to the development of pharmaceutical machinery. So this topicdesigned to control system of GZP series high speed tablet press machine. Based onthe summary of pharmaceutical machinery, tablet press field, on the basis of researchresults at home and abroad, tablet press is introduced the classification of differentsituation, characteristics and working principle; Tablet production methods areintroduced, tablet production process, and the whole production line equipment;Mechanical structure of the tablet press is analyzed, the function of each component,working process and principle of production; Use of electrotechnics, electric drive, theapplication of basic principle and application of PLC, touch screen, the principle andapplication of frequency converter and other theories to GZP series high-speed tablet press machine control system was analyzed, the hardware structure are described. Onthis basis, combining with PLC and touch screen related to software programmingmanual design, through the laboratory test and field debugging, this topic research thePLC+touch screen control system debugging and running, the field can achievetablet press control function in the correct order, and the program is running stableand reliable. The use of touch screen man-machine interaction ability to strengthen,enable employees to convenient operation and monitoring the machine equipment.
