Precise medicine-falling control system of medicine-falling machine

Abstract

The invention discloses a precise medicine-falling control system of a medicine-falling machine. The precise medicine-falling control system comprises a combined-type medicine-falling cover, a cover controlling mechanism, a weighing mechanism and a controller. The weighing mechanism is used for detecting the weight of medicines in a medicine box. The cover controlling mechanism is used for drivingthe combined-type medicine-falling cover to rotate and controlling the medicine-falling amount of the medicines in a medicine bottle into the medicine box through the combined-type medicine-falling cover. The combined-type medicine-falling cover is used for being connected to the medicine bottle and controlling medicine-falling of the medicines in the medicine bottle through rotating. The controller is used for obtaining the prescription weight value of the medicines in prescription information and controlling the combined-type medicine-falling cover through the cover controlling mechanism todo reciprocating rotating back and forth towards the two opposite directions so as to make the combined-type medicine-falling cover to rotate for precise medicine-falling. Meanwhile, the medicine weight value transmitted by the weighing mechanism is obtained, and when the weight value reaches the prescription weight value, the cover controlling mechanism is controlled to stop driving the combined-type medicine-falling cover to conduct medicine-falling. By means of the mode, the precise medicine-falling control system of the medicine-falling machine can realize precise measurement of the medicines.

Description

technical field [0001] The invention relates to the field of automatic control of medicine dispensing, in particular to a precise medicine dispensing control system of a medicine dispensing machine. Background technique [0002] my country's traditional Chinese medicine culture has a long history and is rich in traditional Chinese medicine resources. In recent years, due to the outstanding advantages of traditional Chinese medicine such as good curative effect, less side effects, and less environmental pollution, the "traditional Chinese medicine craze" has become popular in the world. However, at present, China only accounts for a small part of the export volume of traditional Chinese medicine in the world. The main reason is that my country is still using the traditional method of dispensing raw crude medicine and weighing by hand. The speed of dispensing traditional Chinese medicine is slow and the measurement error Large, and it is difficult to connect with the standardi...

Problems solved by technology

However, the existing drug dispensing machine only has two ways of driving the combined drug dispensing cap: rotation and stop. Due to the different bulk densities of different medicines, the dispensing weight of the medicine is inconsistent, resulting in the weight of each dispensing medicine being less than or even greater than the prescription weight. Thus affecting the measurement accuracy and the efficacy of the drug
