[0017] The beneficial effects of this invention are:

[0018] 1. This invention includes a storage device for storing medicines and a transfer mechanism for transferring medicines. The storage device includes a storage rack and several shelves arranged from top to bottom within the storage rack to support medicine boxes. The transfer mechanism includes a movable frame and a transfer trolley disposed within the movable frame and moving up and down within the movable frame. The transfer trolley is equipped with a gripping mechanism for gripping medicine boxes onto the shelves. When refilling medicines in the pharmacy, the movable frame moves to the replenishment mechanism, places the medicine boxes to be replenished onto the transfer trolley, and then the movable frame moves to the corresponding storage rack. The transfer trolley moves up and down to align with the corresponding shelf, and the gripping mechanism grips the medicine box onto the corresponding shelf, thus realizing automatic replenishment and storage of medicines. The transfer of medicines can be achieved through a single transfer mechanism, resulting in low cost.

[0019] 2. The gripping mechanism of this invention includes grippers symmetrically arranged on the transfer trolley. The transfer trolley contains a moving rod that moves back and forth within it. The moving rod has symmetrically arranged first sleeves. The upper surface of the transfer trolley has symmetrically arranged first guide holes. Each first guide hole includes a straight section at its front end and an outwardly curved arc section at its rear end. A second sleeve, which mates with the first guide hole, is located at the upper end of the first sleeve. When the moving rod moves back and forth, the grippers rise and fall under the action of a linkage mechanism. The front ends of the grippers are connected via a connecting mechanism. After the medicine boxes are neatly arranged on the transfer trolley, the moving rod moves forward. Under the action of the first guide hole and the second sleeve, the grippers on both sides move synchronously and in the same direction, gripping the medicine boxes. As the moving rod moves forward, the medicine boxes are gripped onto the shelf. This mechanical mechanism achieves the linkage between the forward movement of the grippers and the clamping of the medicine boxes, eliminating the need for a separate drive, resulting in low cost and high reliability.

[0020] 3. The connecting mechanism in this invention includes support rods disposed inside the grippers. Two support rods are coupled at their inner ends, and tension springs are mounted on the support rods. The two ends of the tension springs are respectively connected to the two grippers. The front end of each gripper has an inclined plate that slopes outward from back to front. The front end of the shelf has stop bars that respectively engage with the inclined plates at the front ends of the two grippers. When the grippers on both sides move the medicine box forward to the foremost position, the inclined plates at the front ends of the grippers contact the corresponding stop bars, and the two grippers open outward against the elastic force of the tension springs, releasing the medicine box. The medicine box is then placed on the shelf. The release of the medicine box is achieved through a mechanical mechanism, eliminating the need for a separate drive to open the grippers, resulting in low cost and high reliability of the mechanical linkage.

[0021] 4. The linkage mechanism in this invention includes a lifting rod disposed at the rear end of the gripper. The lower end of the lifting rod extends into the second sleeve and moves up and down within the lifting rod. A guide plate is disposed on the outside of the lifting rod on the transfer trolley. The guide plate has a second guide hole, which includes a straight section at the front end and a downwardly curved arc section at the rear end of the straight section. A drive rod that mates with the second guide hole is disposed at one end of the cylindrical surface of the lifting rod. When the gripper moves forward, it rises under the action of the drive rod and the second guide hole. When conveying the drug to the shelf, there is no interference with the positioning groove. Moreover, the mechanical linkage method results in low cost. Attached Figure Description

[0030] To enable those skilled in the art to better understand the technical solutions of this invention, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this invention.

[0031] like Figure 1 As shown, a drug storage system includes a storage device for storing drugs and a transfer mechanism for transferring drugs. The storage device includes a storage rack 1 and several shelves 2 arranged from top to bottom within the storage rack 1 to support medicine boxes. Several storage racks 1 are arranged side by side. The transfer mechanism includes a movable frame 3 and a transfer trolley 4 disposed within the movable frame 3 and moving up and down within the movable frame 3. The movable frame 3 is equipped with wheels at its lower end. The transfer trolley 4 is equipped with a gripping mechanism for gripping medicine boxes onto the shelves. When the pharmacy refills drugs, the movable frame 3 moves to the refilling mechanism, places the medicine box to be refilled onto the transfer trolley 4, and then the movable frame 3 moves to the corresponding storage rack. The transfer trolley 4 moves up and down to align with the corresponding shelf 2, and the gripping mechanism grips the medicine box onto the corresponding shelf, realizing automatic drug refilling and storage. Drug transfer can be achieved through a single transfer mechanism, resulting in low cost.

[0032] like Figure 4 , Figure 5 and Figure 6 As shown, the gripping mechanism includes grippers 10 symmetrically arranged on the transfer trolley 4. The transfer trolley 4 has a movable rod 11 that moves back and forth within it. First sleeves 12 are symmetrically arranged on the movable rod 11, fitting onto and moving within it. First guide holes 13 are symmetrically arranged on the upper surface of the transfer trolley 4. Each guide hole 13 includes a straight section at its front end and an outwardly curved arc section at its rear end. A second sleeve is provided at the upper end of the first sleeve 12 to mate with the first guide hole 13. 22. The upper end of the second sleeve 22 passes through the first guide hole 13. When the moving rod 11 moves back and forth, the gripper 10 rises and falls under the action of the linkage mechanism. The front end of the gripper 10 is connected through the connecting mechanism. After the medicine box is neatly arranged on the transfer trolley 4, the moving rod 11 moves forward. Under the action of the first guide hole 13 and the second sleeve 22, the grippers 10 on both sides move synchronously and in the same direction to clamp the medicine box. As the moving rod moves forward, the medicine box is picked up and placed on the shelf. The mechanical mechanism realizes the linkage between the forward movement of the gripper 10 and the clamping of the medicine box by the gripper 10. No separate drive is required, which is low in cost and has good reliability.

[0033] like Figure 2 and Figure 5As shown, the connecting mechanism includes support rods 17 disposed inside the grippers 10. Two support rods 17 are joined at their inner ends, and tension springs 18 are mounted on the support rods 17. The two ends of the tension springs 18 are respectively connected to the two grippers 10. The front end of each gripper 10 has an inclined plate 19 that slopes outward from back to front. The front end of the shelf 2 has stop bars 20 that respectively cooperate with the inclined plates 19 at the front ends of the two grippers 10. When the grippers 10 on both sides clamp the medicine box and move it forward to the frontmost position, the inclined plates 19 at the front ends of the grippers 10 contact the corresponding stop bars 20. The two grippers 10 overcome the elastic force of the tension springs 18 and open outward, releasing the medicine box. The medicine box is placed on the shelf 2. The release of the medicine box is achieved through a mechanical mechanism, eliminating the need for a separate drive to open the grippers, resulting in low cost and good mechanical linkage reliability. Supported by the two support rods, the tension springs 18 pull the two grippers inward without preventing the medicine box from entering between the grippers.

[0034] like Figure 1 As shown, the shelf 2 is provided with a positioning groove 5 for positioning medicine boxes. The medicine boxes are positioned by the positioning groove, so that the medicine boxes are arranged neatly in the positioning groove.

[0035] like Figure 3 As shown, the transfer trolley 4 has first guide sleeves 6 on both sides that are fitted onto the column of the movable frame 3. The transfer trolley 4 is equipped with a motor 7, and a gear 8 is mounted on the output shaft of the motor 7. A rack that meshes with the gear 8 is mounted on the column of the movable frame 3. The motor 7 drives the gear 8 to rotate, and under the action of the gear and rack, the transfer trolley 4 moves up and down within the movable frame 3.

[0036] like Figure 4 As shown, the transfer trolley 4 is equipped with a conveyor belt 9, which continuously transports the medicine boxes forward, so that the medicine boxes are neatly arranged on the transfer trolley 4.

[0037] like Figure 6 As shown, the transfer trolley 4 is provided with guide rods 14 arranged at both ends, and the moving rod 11 is provided with second guide sleeves 15 that cooperate with the guide rods 14 at both ends.

[0038] like Figure 6 As shown, the transfer trolley 4 is equipped with a synchronous belt 16 connected to the moving rod 11. The front and rear ends of the transfer trolley 4 are equipped with synchronous pulleys that cooperate with the synchronous belt 16. The synchronous pulleys are driven to rotate by the motor, which in turn drives the synchronous belt 16 to rotate, thereby realizing the movement of the moving rod 11.

[0039] like Figure 4As shown, the linkage mechanism includes a lifting rod 21 located at the rear end of the gripper 10. The lower end of the lifting rod 21 extends into the second sleeve 22 and moves up and down within the lifting rod 21. A guide plate 23 is provided on the outside of the lifting rod 21 on the transfer trolley 4. The guide plate 23 has a second guide hole 24, which includes a straight section at the front end and a downwardly curved arc section at the rear end of the straight section. A drive rod 25 that mates with the second guide hole 24 is provided at one end of the cylindrical surface of the lifting rod 21. When the gripper 10 moves forward, it rises under the action of the drive rod 25 and the second guide hole 24. When conveying drugs to the shelf, there is no interference with the positioning groove 5, and the mechanical linkage method results in low cost.

[0040] like Figure 4 As shown, a slider 26 is provided on the outer cylindrical surface of the lifting rod 21, and a groove is provided on the inner wall of the second sleeve 22 to cooperate with the slider 26.

[0041] like Figure 4 As shown, the rear end of the gripper 10 is provided with a third sleeve 27 that is rotatably connected to the upper end of the lifting rod 21.
