A bottle dispensing system includes multiple dispensing machines, as well as a first conveying line, multiple second conveying lines, and a third conveying line. The first conveying line is used to send empty bottles to the bottle dispensing system. The second conveying line is used to transport loaded bottles with finished drugs. The third conveying line transports loaded bottles with finished drugs to the next conveying line. The present invention can ensure that the bottles are orderly diverted and dispensed, thereby improving the efficiency of the pharmaceutical production.
