Background art:

at present, the automatic traditional Chinese medicine rooms in the market mainly aim at two types of traditional Chinese medicine formula granules and small-package traditional Chinese medicine decoction pieces. Because the automatic pharmacy of western medicines is mature, and the two types of traditional Chinese medicines are similar to the western medicines, the two types of traditional Chinese medicines can be quantitatively packaged, small-package traditional Chinese medicines with different specifications can be conveniently prepared, and automatic allocation is easy to realize. However, the traditional Chinese medicine is the traditional Chinese medicine in China, and the biggest characteristic of the traditional Chinese medicine is dialectical treatment, a prescription is set out according to the specific condition of each patient, and the weight of the small-package traditional Chinese medicine decoction pieces is only of a plurality of specifications, so that the traditional Chinese medicine cannot be set out according to the state of illness of the patient, the reasonable medicine use of the traditional Chinese medicine is influenced, the characteristics of dialectical treatment of the traditional Chinese medicine cannot be fully exerted, and even the rehabilitation of the patient is possibly influenced. In the traditional Chinese medicine field, whether the efficacy of the traditional Chinese medicine formula granules is the same as that of the decocted traditional Chinese medicine exists.

Nineteen incompatibilities and eighteen antagonisms of the traditional Chinese medicine are incompatibility of the traditional Chinese medicine, are remembered when buying the traditional Chinese medicine and are needed when dispensing the traditional Chinese medicine, so that the situation that various medicinal materials in a traditional Chinese medicine decoction piece dispensing system cannot be subjected to cross contamination in the dispensing process is required.

The dispensing system in the existing market can not thoroughly solve the problem of no cross contamination of the traditional Chinese medicine decoction pieces, and can not meet the market demand in dispensing efficiency and precision. Therefore, the development of an intelligent dispensing system suitable for the traditional Chinese medicine decoction pieces without cross contamination is always the return of hope. Chinese patent document CN211768060U provides a conveyor for bulk herbal pieces prepared for decoction in traditional chinese medicine pharmacy, the utility model discloses a conveyor for bulk herbal pieces prepared for decoction in traditional chinese medicine pharmacy, which comprises a tipping bucket, a chain sprocket, a beam, and a support frame, wherein the support frame is used for supporting the beam and is fixed with the ground or a certain platform. In the technology, a tipping bucket is responsible for taking a plurality of traditional Chinese medicines, and the situation of cross contamination of a system caused by medicine splashing can occur when the medicines fall. Chinese patent document CN209291244U provides a "full-automatic bulk chinese medicine dispensing machine", and the utility model discloses a dispensing device for bulk chinese medicine decoction pieces, but the device has a medicine dropping channel shared by multiple medicinal materials, resulting in cross contamination between the medicinal materials. Therefore, the improvement of the dispensing technology of the bulk traditional Chinese medicine decoction pieces is imperative.
