Description

Chemical dispensing device

The present invention relates to a medicine dispensing device for supporting a dispensing operation in a hospital pharmacy or the like, and in particular, various medicines are stored in a number of cassettes in advance, and automatically when necessary. The present invention relates to a medicine dispensing apparatus for dispensing.

Japanese Patent Application Laid-Open No. 2012-139249 (Patent Document 1) discloses that a medicine in a cylindrical container such as an ampoule is stored in alignment in a storage cassette, and the medicine is discharged from a medicine discharge unit, and then a transfer input device. A conventional chemical dispensing device that transfers the product to the transport tray and discloses it is disclosed. In this conventional medicine dispensing apparatus, when the transfer input device receives discharged chemicals, the lower surface of the transfer container is closed and the chemicals are put into the transfer container from the upper surface. The chemicals handled by this chemical dispensing device are so-called round pharmaceutical products such as injections placed in a cylindrical container such as an ampoule. An infusion bottle or the like is applicable if it is in a cylindrical container. In the conventional medicine dispensing device, when the chemicals are put into the transfer tray from the transfer container, the transfer container is lowered so that the lower surface of the transfer container is placed in the inner space of the transfer tray and then the lower surface of the transfer container is opened. To do. And the transmission part by support is integrated in the transmission path of a transmission mechanism, and if the fall of a transfer container is prevented, the transmission of the driving force and movement which lower a transfer container will be cut off. According to the conventional medicine dispensing device, the transfer container that receives the chemicals discharged from the storage cassette and transports the chemicals to the transfer tray performs the reception on the open upper surface and the loading on the open / close lower surface. The lowered transfer container is further lowered and the lower surface is placed in the internal space of the transfer tray, and then the lower surface of the transfer container is opened and charged. Therefore, it is possible to realize a chemical dispensing device that can accurately put chemicals in a cylindrical container into the transport tray not only when the transport tray is shallow but also when the transport tray is deep. In addition, in the conventional medicine dispensing device, even if there are a lot of chemicals that have already been introduced or if the chemicals that have already been introduced stand by accident, they have already been put into the transport tray. When the tip of the transfer container comes into contact with the chemicals that are present, the transfer container is prevented from descending, so that there is no possibility that the chemicals are broken by the impact of the collision. In this medicine dispensing device, the medicine cannot be put into the transfer tray while the transfer feeding device accepts the medicine from the medicine discharging unit. Therefore, in the medicine dispensing apparatus disclosed in Japanese Patent No. 5564868 (Patent Document 2) and the like, the transfer input device is divided into a transfer mechanism and an input mechanism, and the transfer and input are performed separately.
