Description

Injection medicine storage sorting device with medicine outlet at bottom Technical Field The invention relates to medical automation equipment, in particular to a device for automatically storing and sorting injection medicines (such as penicillin bottles and ampoule bottles) in a hospital static distribution center (PIVAS). Background With the development of medical industry, the prescription amount of a static distribution center of a hospital is increased increasingly, and higher requirements are put on the efficiency, accuracy and safety of medicine preparation. The automatic storage and sorting of injection medicines are realized, and the automatic storage and sorting method is one of key links for improving the overall efficiency of a static distribution center. A variety of automated vial storage and sorting schemes have emerged in the prior art and can be broadly divided into two categories: The first type of solution, as shown in the published patent CN112607289a and CN214568141U, adopts a combination of medicine basket buffering and robot picking. It generally comprises a plurality of layers of medicine basket buffer racks of medicine bottles to be sorted, a conveying line connected with the buffer racks, and a sorting robot provided with a vision device. During operation, medicine basket conveying lines for loading medicine bottles to be sorted are conveyed to two sides of the sorting station robot. At the same time, the basket loaded with the basal infusion is also fed under the picking station. The robot grabs the medicine bottles one by one from the medicine baskets at the two sides according to prescription information, places the medicine bottles into the medicine basket at the lower part, then the medicine basket at the lower part is conveyed to the liquid distribution ring joint, and the medicine baskets at the two sides are conveyed back to the cache frame. However, the scheme has the defects that firstly, the medicine basket for loading the medicine bottles to be picked is transmitted back and forth and the picking mode of a robot at a fixed station is adopted, so that each picking action is accompanied by waiting and moving of the medicine basket, the overall medicine taking beat is longer, the efficiency is limited, secondly, a conveying line and a special picking station are required to be arranged in the whole system, the occupied area of equipment is large, and the layout difficulty and the construction cost of a static distribution center are increased. The second type of solution, as shown in the published patent CN111292473a and CN209480707U, employs a combination of dense storage and direct grasping by a robot. It typically aligns the vials vertically in a cartridge-like vial holder (magazine) and pushes the vials toward the front of the vial holder by a pushing mechanism. The gripping manipulator is provided with gripping fingers, the gripping fingers are moved to the front end of the designated medicine bottle clamp, the medicine bottle at the forefront end is directly gripped, the gripping fingers are separated from the medicine bottle clamp in an upward lifting mode, and the gripping fingers can be placed on a carrier for transferring. Such a solution significantly increases storage density by packaging the vials in a vial clip. However, there is still a need for improvement in that, first, the gripping fingers need to extend into the vial holder and open at an angle to grip the body when gripping the vials, which requires enough space between adjacent vials for movement of the fingers, which limits the ultimate density of the vial layout to a certain extent. Secondly, for small-size medicine bottles, not only enough clamping width and strength of clamping fingers are ensured, but also enough height of the enclosing wall of the medicine bottle clamp is ensured so as to maintain the vertical stability of the medicine bottle in the pushing and grabbing processes, and the two have a certain contradiction in structural design. Therefore, improving the existing high-density storage scheme, further optimizing the action mode and structure of the sorting mechanism, and realizing higher-density storage is a technical problem to be solved by the person skilled in the art. Notably, prior art sorting actuators (whether gripping fingers or suction cups) all employ a "active gripping and removal of vials from outside the magazine". This mode is limited by the space of action, response speed and beat of reciprocation of the sorting actuators, and there are still physical bottlenecks in pursuing extreme efficiency and extremely dense set storage. If the thinking of 'external grabbing' can be broken, a brand new sorting mode of 'actively releasing from the inside of the medicine box and automatically dropping medicine bottles by gravity' is explored, the space limitation of the sorting mechanism on the medicine bottle arrangement space is hopefully eliminated fundamentally, and the physical
