[0036] Please refer to Figures 1 to 7 , an embodiment of the present utility model provides a dispensing device for unpackaged drugs, which is installed above the medicine delivery belt of a medicine dispenser. The dispensing device for unpackaged drugs includes a frame 1. The frame 1 is provided with a plurality of downwardly inclined medicine storage grooves 2 for storing unpackaged drugs in the vertical direction. The upper opening of each medicine storage groove 2 is a medicine adding port, and the lower opening of each medicine storage groove 2 is a medicine dropping port. The frame 1 is further provided with a flat medicine dropping belt 3 and a belt driving mechanism 4 for driving the flat medicine dropping belt 3 to move. When storing medicine, the belt driving mechanism 4 drives the flat medicine dropping belt 3 to move in the first direction to sequentially block the medicine dropping ports of all the medicine storage grooves 2. When the medicine dropping ports of all the medicine storage grooves 2 are blocked by the flat medicine dropping belt 3, a pharmacist stores unpackaged drugs in each medicine storage groove 2. When dispensing medicine, the belt driving mechanism 4 drives the flat medicine dropping belt 3 to move in the second direction to sequentially open the medicine dropping ports of all the medicine storage grooves 2. When the medicine dropping port of a certain medicine storage groove 2 is opened, due to the downward inclination of the medicine storage groove 2, the unpackaged drugs stored in the medicine storage groove 2 fall onto the medicine delivery belt of the medicine dispenser under the action of gravity, and then are conveyed to the medicine outlet through the medicine delivery belt. Among them, the first direction and the second direction are two directions with opposite directions.

[0037] For the above-mentioned dispensing device for unpackaged drugs, by arranging a plurality of downwardly inclined medicine storage grooves 2 for storing unpackaged drugs in the frame 1 in the vertical direction and cooperating with the flat medicine dropping belt 3 and the belt driving mechanism 4, the storage and automatic dispensing of unpackaged drugs are realized, the deficiencies of the existing automatic medicine dispenser in the dispensing of unpackaged drugs are solved, the application range of the automatic medicine dispenser is expanded, so that it can more comprehensively meet the needs of hospital pharmacies. At the same time, the structure is simple and the occupied space is small.

[0038] Please refer to Figures 1 to 3 , in one embodiment, the frame 1 includes a left frame 11 and a right frame 12 which are oppositely arranged. A plurality of downwardly inclined partition plates 13 are arranged between the left frame 11 and the right frame 12 in the vertical direction. An adjacent two partition plates 13 and the left frame 11 and the right frame 12 form a medicine storage groove 2. The arrangement of the partition plates 13 makes full use of the space inside the frame 1 and can store more drugs. At the same time, the size of each medicine storage groove 2 can be adjusted according to needs to adapt to different types and specifications of drugs, improving the flexibility of the storage space.

[0039] Please refer to Figure 2 , Figure 3, in one embodiment, limiting guide bars 5 are provided on both the left frame 11 and the right frame 12 near the medicine dropping opening side of the medicine storage tank 2. The two limiting guide bars 5 and the left frame 11 and the right frame 12 form a moving guide channel for guiding the medicine dropping flat belt 3 to sequentially block all the medicine dropping openings of the medicine storage tanks 2. The above-mentioned limiting guide bars 5 provide a clear moving path for the medicine dropping flat belt 3, ensuring that the medicine dropping flat belt 3 can accurately pass through and block the medicine dropping opening of each medicine storage tank 2 in sequence. During the operation of the belt, due to various factors (such as uneven tension, uneven friction, etc.), the belt may shift. The presence of the limiting guide bars 5 can effectively prevent such a shift from occurring, ensuring that the belt always remains in the correct position.

[0040] Please refer to Figure 4 , in one embodiment, one end of the medicine dropping flat belt 3 is wound around the medicine adding opening side of the medicine storage tank 2, and the other end of the medicine dropping flat belt 3 is wound around the medicine dropping opening side of the medicine storage tank 2. Among them, when the belt driving mechanism 4 drives the medicine dropping flat belt 3 to move in the first direction, the medicine dropping flat belt 3 sequentially blocks all the medicine dropping openings of the medicine storage tanks 2 and sequentially opens all the medicine adding openings of the medicine storage tanks 2. After all the medicine dropping openings of all the medicine storage tanks 2 are blocked by the medicine dropping flat belt 3 and all the medicine adding openings of all the medicine storage tanks 2 are opened, the pharmacist stores the dispensed medicine in each medicine storage tank 2. When the belt driving mechanism 4 drives the medicine dropping flat belt 3 to move in the second direction, all the medicine dropping openings of the medicine storage tanks 2 are sequentially opened and all the medicine adding openings of the medicine storage tanks 2 are sequentially blocked, realizing the dispensing of the medicine one by one. And when all the medicine adding openings of the medicine storage tanks 2 are blocked by the medicine dropping flat belt 3, at this time, all the medicine storage tanks 2 cannot be filled with medicine.

[0041] Please refer to Figures 1 to 3 , Figure 6 , in one embodiment, the belt driving mechanism 4 is arranged on the top of the frame 1, and a top cover 6 for covering the belt driving mechanism 4 is also arranged on the top of the frame 1. Front belt openings 61 and rear belt openings 62 through which the two ends of the medicine dropping flat belt 3 pass are respectively opened at the front and rear ends of the top cover 6. The above-mentioned top cover 6 provides a closed protection space for the belt driving mechanism 4, which can effectively prevent external factors such as dust, foreign objects or moisture from damaging the driving mechanism, thereby extending its service life and reducing the failure rate, and at the same time does not affect the movement of the medicine dropping flat belt 3.

[0042] Please refer to Figure 4 , Figure 5, in one embodiment, the belt driving mechanism 4 includes a driving motor 41, a driving roller 42 and two pressing rollers 43. The driving motor 41 is fixed in the top cover 6 through a fixing seat 44. The driving shaft of the driving motor 41 is connected to the driving roller 42 to drive the driving roller 42 to rotate. The two pressing rollers 43 are rotatably arranged in the top cover 6 and are located on the front and rear sides above the driving roller 42. The upper and lower surfaces of the medicine dropping flat belt 3 are respectively abutted against the driving roller 42 and the two pressing rollers 43, that is, the two pressing rollers 43 press the medicine dropping flat belt 3 on the driving roller 42. When the driving roller 42 rotates, the friction between the driving roller 42 and the medicine dropping flat belt 3 drives the medicine dropping flat belt 3 to move stably and reliably in the first direction or the second direction. Due to the friction between the driving roller 42 and the medicine dropping flat belt 3, the moving speed and direction of the medicine dropping flat belt 3 can be accurately controlled, which helps to achieve the accurate distribution of medicines and ensure that the amount of medicines in each medicine storage tank 2 is accurate.

[0043] Please refer to Figure 5 , in one embodiment, the driving roller 42 has a hollow structure with openings at both ends, and the driving motor 41 is arranged inside the driving roller 42. By placing the driving motor 41 inside the driving roller 42, the floor area of the entire mechanism can be significantly reduced, making the entire belt driving mechanism 4 more compact.

[0044] Please refer to Figure 5 , in one embodiment, the roller surface of the driving roller 42 is covered with friction stripes 421. The setting of the friction stripes 421 can significantly increase the friction coefficient between the driving roller 42 and the medicine dropping flat belt 3, thereby increasing the friction force between them, so that the driving roller 42 can more effectively drive the medicine dropping flat belt 3 to move when rotating and reduce the occurrence of slipping.

[0045] Please refer to Figure 6 , in one embodiment, a guide plate 63 for guiding the medicine dropping flat belt 3 to sequentially block the medicine adding ports of all the medicine storage tanks 2 is arranged below one side of the top cover 6 close to the front belt opening 61. The setting of the guide plate 63 provides a clear moving path for the medicine dropping flat belt 3 to ensure that the medicine dropping flat belt 3 can accurately pass through and block the medicine adding ports of each medicine storage tank 2 in sequence.

[0046] Please refer to Figure 2 , Figure 3 , Figure 7In one embodiment, the frame 1 is provided with an origin sensor 7 and a counting sensor 8, and the medicine dropping flat belt 3 is provided with an origin opening 31 matched with the origin sensor 7 and a plurality of counting openings 32 sequentially arranged along the length direction of the medicine dropping flat belt 3 and matched with the counting sensor 8, and the center distance between two adjacent counting openings 32 is the same as the center distance between two adjacent medicine dropping openings. When the origin opening 31 moves to the sensing position of the origin sensor 7, the medicine dropping flat belt 3 blocks the medicine dropping openings of all medicine storage slots 2. The origin sensor 7 determines the initial position of the medicine dropping flat belt 3 by sensing the origin opening 31 on the medicine dropping flat belt 3. Once the origin is determined, the device can accurately know when to start counting or perform other operations. The counting sensor 8 cooperates with the plurality of counting openings 32 on the medicine dropping flat belt 3 to accurately detect and record the number of times or positions of the belt movement. Since the center distance between two adjacent counting openings 32 is the same as the center distance between two adjacent medicine dropping openings, the counting sensor 8 can accurately know when each medicine dropping opening is opened or closed, thereby realizing accurate control of medicine distribution. Through the cooperation of the origin sensor 7 and the counting sensor 8, it can be ensured that the drug dispensing equipment maintains high precision and stability during the entire operation process, so as to reduce errors and improve the accuracy and consistency of drug dispensing.

[0047] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the claims attached to the utility model.

[0048] The above is an exemplary description of the utility model patent in conjunction with the accompanying drawings. It is obvious that the implementation of the utility model patent is not limited to the above-mentioned method. As long as various improvements are made by adopting the method concept and technical solution of the utility model patent, or the concept and technical solution of the utility model patent are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
