Problems solved by technology

[0002] At present, traditional Chinese medicine is often prepared manually in the dispensing process. Since a pair of traditional Chinese medicine contains many types of Chinese medicine ingredients, and the weight of each medicine ingredient is different, the manual dispensing time of Chinese medicine in the dispensing process is relatively long. less, and the accuracy of dispensing is prone to large fluctuations
At present, due to the complexity of the dispensing process of traditional Chinese medicine, there is no automated system or equipment for dispensing traditional Chinese medicine. Even in some special places for dispensing traditional Chinese medicine, they either use manual dispensing methods or very complicated dispensing devices, so that this This dispensing system is difficult to popularize and apply in a large number of pharmacies of traditional Chinese medicine hospitals

Abstract

The invention discloses an automatic dispensing system based on a PLC and an application method. The automatic dispensing system based on PLC comprises a PLC controller, a PID controller, a drug tank, a conveying belt, a drive motor, a return cylinder, a dispensing cylinder, an electronic scale, a PLC move controller and a sliding trolley. The PLC controller controls the sliding trolley to take the needed drugs from a drug storage and send the drugs to the drug tank; the drugs in the drug tank drop into the conveying belt through vibration and are sent to the dispensing cylinder through the conveying belt; the electronic scale is mounted under the dispensing cylinder and is monitored at real time through the PLC controller so as to precisely measure the weight of the drugs in the dispensing cylinder. The automatic dispensing system based on the PLC and the application method achieves the purpose of automatically filling the prescription precisely.
