[0043] The present invention will be further described below in conjunction with the drawings and embodiments.

[0044] First embodiment

[0045] Refer to Figures 1 - 9 , the loose drug dispensing device involved in this embodiment includes

[0046] a drug delivery channel A for transporting drugs, and the drug delivery channel A is arranged in a special shape;

[0047] a mounting structure for mounting and fixing the medicine bottle 6, and the inner cavity of the medicine bottle 6 is used for storing loose drugs;

[0048] The inner cavity of the medicine bottle 6 communicates with the medicine inlet A1 at one end of the medicine outlet channel A, and the medicine outlet A2 at the other end of the medicine outlet channel A communicates with the outside; the medicine outlet channel A involved in this embodiment is rotatably arranged. When the medicine outlet channel A rotates to a position where the medicine outlet A2 is lower than the medicine inlet A1, the medicine outlet channel A forms a downward-sloping conveying trajectory, so that the medicine is finally poured out through the medicine outlet A2.

[0049] Further, a buffer medicine storage part 103 is provided on the medicine outlet channel A. The buffer medicine storage part 103 is located between the medicine inlet A1 and the medicine outlet A2 and deviates from the connection line A3 between the medicine inlet A1 and the medicine outlet A2. The buffer medicine storage part 103 has a buffering and storing effect on the medicine. When the medicine outlet channel A reciprocally rotates to achieve the effect of shaking the medicine, if the scattered medicines are crowded or blocked at the medicine outlet A2, causing the medicine to not pass through the medicine outlet A2, it is necessary to rotate the medicine outlet channel A back to the initial position. At this time, some medicines will stay in the buffer medicine storage part 103, avoiding all the medicines from flowing back into the medicine bottle 6. When the medicine outlet channel A rotates again, the medicines are conveyed in sequence, effectively solving the problem of congestion or blockage.

[0050] Further, the buffer medicine storage part 103 deviates towards the lower position, and the angle α between the deviation direction and the vertical direction is 0° - 45°. See Figure 7 , the angle α is preferably 30°. The buffer medicine storage part 103 makes the bottom of the medicine outlet channel A form a fluctuating and bent conveying trajectory, extending the conveying distance, which is beneficial to the orderly conveying of the medicine; a first conveying part 102 is provided between the buffer medicine storage part 103 and the medicine inlet A1. The small end of the first conveying part 102 communicates with the medicine inlet A1, and the large end communicates with the buffer medicine storage part 103; a second conveying part 104 is provided between the buffer medicine storage part 103 and the medicine outlet A2. The large end of the second conveying part 104 communicates with the buffer medicine storage part 103, and the small end communicates with the medicine outlet A2; the conveying stroke of the first conveying part 102 is less than or equal to the conveying stroke of the second conveying part 104.

[0051] Further, a bottle cap cover 101 covering the bottle mouth of the medicine bottle 6 is provided on the medicine inlet A1. The bottle cap cover 101 is arranged in a flared shape, which can adapt to bottle mouths of different sizes to fit different medicine bottles 6, and thus can meet the storage requirements of different types of medicines; the opening size of the medicine inlet A1 is preferably such that more than one medicine can enter and exit simultaneously; the opening size of the medicine outlet A2 is preferably such that one medicine can enter and exit simultaneously, so as to facilitate the orderly discharge of the medicine; the medicine outlet A2 is connected to a sorting bend 105 with a non-linear conveyance. The sorting bend 105 is connected to a medicine outlet position 106; the medicine decelerates in the sorting bend 105 and reaches the medicine outlet position 106 in an orderly manner. The medicine outlet position 106 only allows one medicine to be stored to ensure that one medicine is extracted each time.

[0052] Further, the installation structure includes a first clamping block 2 and a second clamping block 4. The first clamping block 2 and the second clamping block 4 elastically approach each other to elastically clamp the medicine bottle 6. Specifically, one end of the first clamping block 2 and one end of the second clamping block 4 are hinged to each other through a hinge shaft 109. A tension spring 3 is arranged between the first clamping block 2 and the second clamping block 4. Under the action of the tension spring 3, the first clamping block 2 and the second clamping block 4 elastically approach each other, forming a clip as a whole, and clamping and fixing the medicine bottle 6 by means of clamping. The installation structure is convenient and fast for disassembling and assembling the medicine bottle 6 and can adapt to medicine bottles 6 of different sizes.

[0053] Further, the loose medicine dispensing device C further includes a rotating bracket 1. The medicine dispensing channel A, the medicine inlet A1, the medicine outlet A2, the bottle cap cover 101, the first conveying part 102, the buffer medicine storage part 103, the second conveying part 104, the sorting bend 105, the medicine dispensing position 106, and the hinge shaft 109 and other structural features are integrally formed on the rotating bracket 1 respectively.

[0054] See Figure 10 and Figure 11 , the medicine storage cabinet involved in this embodiment includes a medicine storage box body G. The loose medicine dispensing device C is rotatably arranged in the inner cavity of the medicine storage box body G. The medicine storage box body G and the loose medicine dispensing device C together form a medicine storage unit. A plurality of medicine storage units are detachably arranged on a cabinet body to form a medicine storage cabinet. The medicine dispensing channel A rotates or swings relative to the medicine storage box body G to complete the medicine dispensing action.

[0055] Further, the loose medicine dispensing device C is rotatably connected to the medicine storage box body G through a rotating shaft 107. A rotating acting part 108 eccentric to the rotating shaft 107 is arranged on the side of the loose medicine dispensing device C. The rotating acting part 108 drives the medicine dispensing channel A to rotate or swing relative to the medicine storage box body G under the action of the push rod 7. Specifically, the rotating shaft 107 and the rotating acting part 108 are integrally formed on the rotating bracket 1 respectively; the push rod 7 is arranged on the robot and is controlled by the robot to move; a counterweight block 5 eccentric to the rotating shaft 107 is arranged on the rotating bracket 1. When the loose medicine dispensing device C is not affected by other external forces, the gravity of the counterweight block 5 drives the loose medicine dispensing device C to automatically reset and rotate to the initial position. See Figure 12 , the loose medicine dispensing device C is in the initial position (medicine returning position), and the push rod 7 is also in the initial position; see Fig. 13, the push rod 7 moves horizontally (moves to the left as shown in the figure), the push rod 7 touches the rotating acting part 108 at the set position, and the push rod 7 continues to move horizontally to drive the medicine dispensing channel A to rotate directionally (rotates clockwise as shown in the figure) through the rotating acting part 108; see Figure 14 , when the push rod 7 moves horizontally to a certain position, the horizontal movement action of the push rod 7 can no longer drive the medicine dispensing channel A to rotate directionally through the rotating acting part 108; see Figure 15, the push rod 7 moves upward, enabling the push rod 7 to drive the medicine outlet channel A to rotate directionally again through the rotation action part 108 (clockwise rotation as shown in the figure).

[0056] See Figures 16 - 19 , for the medicine discharging method involved in this embodiment, the moving positions of the medicine outlet channel A are divided into a medicine returning position, a medicine shaking position, an inspection position, and a medicine discharging position; the medicine discharging method includes the following steps.

[0057] Step 1, medicine shaking and inspection: The medicine outlet channel A rotates from the medicine returning position to the inspection position.

[0058] Step 2, pouring and discharging medicine: When the medicine outlet A2 detects medicine, the medicine outlet channel A rotates from the inspection position to the medicine discharging position, and the medicine is discharged from the medicine outlet A2 to complete the medicine discharging; when the medicine outlet A2 does not detect medicine, the medicine outlet channel A rotates from the inspection position to the medicine shaking position and then returns to the inspection position until the medicine outlet A2 detects medicine, and then the medicine outlet channel A rotates from the inspection position to the medicine discharging position, and the medicine is discharged from the medicine outlet A2 to complete the medicine discharging.

[0059] Step 3, resetting and returning medicine: After completing the medicine discharging action, the medicine outlet channel A rotates from the medicine discharging position to the medicine returning position, and the medicine in the medicine outlet channel A returns to the medicine bottle 6.

[0060] Further, there is a connection line A3 between the medicine inlet A1 and the medicine outlet A2.

[0061] When the medicine outlet channel A is in the medicine returning position, the included angle β1 between the conveying track and the horizontal plane is 75°.

[0062] When the medicine outlet channel A is in the medicine shaking position, the included angle β2 between the conveying track and the horizontal plane is 30°.

[0063] When the medicine outlet channel A is in the inspection position, the included angle β3 between the conveying track and the horizontal plane is -45°.

[0064] When the medicine outlet channel A is in the medicine discharging position, the included angle β4 between the conveying track and the horizontal plane is -70°.

[0065] Further, in Step 2, when the medicine outlet A2 still does not detect medicine after the medicine outlet channel A rotates more than once, the system determines that there is no medicine in the inner cavity of the medicine bottle 6, and then the medicine outlet channel A rotates from the inspection position to the medicine returning position, and the system issues a prompt for replenishing medicine; when the medicine replenishing work is completed, the system executes the above-mentioned medicine discharging action process again.

[0066] Further, a detection component for detecting medicine is provided on the medicine outlet A2, the sorting bend 105 or the medicine discharging position 106, and this detection component is preferably an electronic eye device.
