The medicine cup is an intermediate container for containing the formula tablets, and the medicine cup flows on the circular line at the bottom of the cabinet 1 in a working state and is not in contact with the outside. The circulation of the medicine cup starts from the endowment of the prescription and is finished until the arranged medicine particles are discharged to the pouring opening 9-5, the working condition of the outpatient medicine prescription is special, and the circulation is usually repeated for more than ten cycles. Each medicine cup is provided with a unique RFID label and an identification code thereof, the code is the mapping of the medicine cup in an information system, and in the information system, the medicine cup not only contains the information of tablets, but also contains the information of patients, the information of transfer circulation and the like. The medicine cup management has two aspects, namely prescription scheduling and medicine cup running state control.

During the prescription, the control system needs to balance the load of at least four pouring openings 9-5, and the medicine of one patient is sealed by a sealing machine communicated with the pouring openings 9-5 in habit, so that the receiving work of the medicine outlet end is well ordered, and therefore different prescriptions are always processed by the medicine dispensing cabinet 1 at any time. The plurality of storage tube bodies contained in the manifold assembly are mutually exclusive, errors can occur when the medicine discharge interval is too short, so that the prescriptions executed by adjacent medicine cups need to be prevented from using several medicines contained in the same manifold, and the medicine cup management mechanism can reasonably schedule the prescriptions to be executed according to the basic principle. In the circulation process of the medicine cups, the RFID and the positions of the medicine cups are identified by the key nodes of the relevant equipment in the cabinet 1.
