The rapid rise of PLC control technology has brought good news to the manufacturing industry. While moving toward the industrial production line, it has also rapidly penetrated into the pharmaceutical production line. It is reported that according to the control needs of various production processes and workshop processes in the pharmaceutical industry, an automated PLC control system can be used to intelligently control all links of the production process.

(1) When making embryos, the automated PLC control system is used to control the operation of the barrel and injection molding machine mold, and to distribute the temperature of the main runner and branch runners of the mold. It is also used to control the back and forth operation of the robot taking the embryo. In this way, the finished preform is taken out from the mold to realize fully automated preform making and preform removal operations;

(2) When blowing the bottle, the automatic PLC control system can be used to realize the automatic preform on the track, the automatic preform lifting ring and the welding ring, etc., and it can also be used to control the preform heated in the light box, and the bottle After the embryo is heated, it is transmitted to the mold for blowing;

(3) When dispensing medicines, the automated PLC control system can be used to control the dispensing machine according to the prescriptions to carry out the process of automatically taking out the cups, dispensing the medicines, and encapsulating the medicine cups very accurately. Currently, parameter tables and modular programming techniques are very extensive in actual use. PLC has a very simplified initialization process, which stably and reliably improves the operation and production efficiency of the program;

(4) During filling, the automatic PLC control system can display and set various real-time parameters monitored by the washing, filling and sealing unit, and can also carry out strict control over the whole process, which is constant in the automatic constant pressure tank. Control the filling level, and control the liquid level, pressure and temperature in the whole process of closed-loop filling production;

(5) When sterilizing, it can reflect the great advantages of an automated PLC control system. Generally, a water bath type moist heat sterilization method is used. Due to the large volume of the sterilization cabinet, for large-volume injections, the sterilization effect directly affects the safety of medication. There are more control signals on the periphery of the larger sterilization cabinet. At this time, you can use PLC technology to take advantage of the advantages to expand the module, and you can also convert the external analog signal into a digital signal through the A/D converter, and finally through the logic calculation of the PLC to effectively control and determine the sterilization program and process curve . The sterilization cabinet controlled by an automated PLC control system has very simple programming, and is very versatile, the accuracy of the measured curve is also very high, and the system is also very stable;

(6) During leak detection, the automated PLC control system can use the light source signal from the photoelectric switch to detect the passing bottle, and the output module can also be used to control the actuator to apply a certain degree of pressure to the passing bottle. Therefore, all non-conforming products are eliminated.

(7) When the medicine is packaged, the automatic packaging equipment using the automatic PLC control system has realized the fully enclosed operation in the air intake, exhaust equipment, peristaltic motor and other aspects. The operation process is safe and very Clean and effective.

The production of drugs is a complete system engineering, which emphasizes the safety of production equipment, automated production lines and how to reduce errors in in-situ operations. The rapid rise of PLC control technology has brought good news to the manufacturing industry. While moving towards the industrial production line, it has also rapidly penetrated into the pharmaceutical production line. It makes the pharmaceutical equipment develop from simple control equipment to complex control system, and the operation mode is changed from heavy and dangerous to light and safe. The safe, precise and stable control technology of the automated PLC control system has been popularized in the pharmaceutical process

Through the previous introduction, we can clearly understand that the automated PLC control system can make it easier for the operator to observe various data, can effectively control and process the process in real time, have high reliability, and the accuracy of operation Very high, with good security.
