A baffle mechanism is arranged at the right end of the bottom plate 1 for controlling the sliding of the medicine box above the bottom plate 1; the medicine replenishing mechanism is used to put the medicine box onto the caching mechanism.

[0032] As Figures 4 - 9 shown, the baffle mechanism includes a long strip-shaped through slot 6 opened along the length direction at the right end of the bottom plate 1. On both sides of the bottom of the through slot 6 at the bottom of the bottom plate 1, brackets 7 are fixedly arranged. A swing rod 8 is rotatably hinged on the brackets 7. A long strip-shaped first baffle block 9 is arranged at the right end of the swing rod 8, and a long strip-shaped second baffle block 10 is arranged at the left end of the swing rod 8. A servo motor 12 is fixedly arranged on the brackets 7, and the output shaft of the servo motor 12 can drive the swing rod 8 to swing back and forth. As the swing rod 8 swings, only one of the first baffle block 9 and the second baffle block 10 can protrude above the upper surface of the bottom plate 1.

[0033] The medicine replenishment buffer device provided by the utility model has a simple structure. Through the medicine replenishment mechanism, the medicine boxes of each buffer mechanism can be replenished. The inclined lifting plate 18 is connected to the inclined bottom plate 1, so that the medicine box automatically slides to the right end of the bottom plate 1 under the action of its own gravity, and the medicine replenishment is convenient and fast. The distance between the fixed plate 2 and the adjusting plate 3 in the buffer mechanism is adjustable and can be applied to medicine boxes of different sizes. The distance between the two baffle blocks in the baffle mechanism can be adjusted by reasonably setting the length of the insertion rod 11. According to the medicine box, the distance between the first baffle block 9 and the second baffle block 10 is set so that the distance between the first baffle block 9 and the second baffle block 10 is slightly smaller than the length of the medicine box, which neither affects the sliding of the medicine box to be dispensed nor can timely block the next medicine box to be dispensed, preventing misdispensing and greatly improving the accuracy of the dispensed medicine quantity.

[0034] In this embodiment, a hinge shaft 801 is provided in the middle of the swing rod 8. The hinge shaft 801 is coaxially connected to the output shaft of the servo motor 12. A square slot 802 is opened at the left end of the swing rod 8. One end of the second baffle block 10 close to the swing rod 8 is fixedly provided with an insertion rod 11, and the insertion rod 11 is inserted into the slot 802.

[0035] As a further optimization, the included angle between the first baffle block 9 and the second baffle block 10 is an obtuse angle, so that when the first baffle block 9 or the second baffle block 10 is located above the bottom plate 1, its length direction can be perpendicular to the upper surface of the bottom plate 1.

[0036] As a further optimization, for different medicine box sizes, a plurality of second baffle blocks 10 with different lengths of insertion rods 11 are provided.

[0037] As a further optimization, a telescopic mechanism is fixedly provided in the slot 802. The telescopic mechanism is fixedly connected to the insertion rod 11. The telescopic mechanism can adopt an electric screw. According to the different lengths of the medicine boxes, the distance between the first baffle block 9 and the second baffle block 10 is adjusted through the telescopic mechanism.

[0038] In this embodiment, a plurality of the buffer mechanisms are arranged in a rectangular array along the vertical plane, and the plurality of buffer mechanisms are fixedly connected together through a frame. As Figures 10 - 12As shown in the figure, the tonic replenishing mechanism includes two first oil cylinders 13 arranged in parallel up and down and one second oil cylinder 14 arranged vertically. Both the first oil cylinder 13 and the second oil cylinder 14 are rodless oil cylinders. The second oil cylinder 14 is fixedly arranged on the moving blocks of the two first oil cylinders 13. The moving block of the second oil cylinder 14 is fixedly connected to a tonic replenishing plate 16 arranged obliquely with the left end lower and the right end higher. A lifting plate 18 is arranged perpendicular to the upper side of the tonic replenishing plate 16. The lifting plate 18 is arranged with the left end higher and the right end lower. An installation plate 20 is arranged at the lower end of the tonic replenishing plate 16. A telescopic mechanism 19 for driving the lifting plate 18 to slide along the length direction of the tonic replenishing plate 16 is arranged on the installation plate 20. The upper end position of the tonic replenishing plate 16 is connected to the left end position of the bottom plate 1. After the upper end of the tonic replenishing plate 16 is aligned with the left end of the bottom plate 1 of the corresponding buffer mechanism, as the telescopic mechanism 19 controls the lifting plate 18 to rise, multiple medicine boxes stacked on the lifting plate 18 slide down one by one under the action of gravity to the bottom plate 1 of the buffer mechanism. The telescopic mechanism 19 is an electric screw rod, a hydraulic rod or a cylinder rod. As a further optimization, a ranging sensor is also arranged on the tonic replenishing mechanism, which is used to detect the distance between the leftmost medicine box on the bottom plate 1 and the left end of the bottom plate 1, and is used to judge the number of medicine boxes to be replenished.

[0039] One side of the tonic replenishing plate 16 close to the second oil cylinder 14 is higher than the side away from the second oil cylinder 14. A side baffle 17 is arranged on the side of the tonic replenishing plate 16 away from the second oil cylinder 14, so that the medicine box will not fall during the movement along with the replenishing mechanism.

[0040] A square sleeve 15 is sleeved outside the second oil cylinder 14. The sleeve 15 is fixedly arranged with the moving block of the second oil cylinder 14. One tonic replenishing plate 16 is fixedly arranged on each side of the sleeve 15, improving the tonic replenishing efficiency.

[0041] Specific working process:

[0042] 1. Manually place the medicine box on the lifting plate 18. Under the action of the first oil cylinder 13 and the second oil cylinder 14, the medicine box is transported to the position of the buffer mechanism to be replenished with medicine;

[0043] 2. Control the lifting plate 18 to drive the medicine box to rise through the telescopic mechanism 19. When the uppermost medicine box is higher than the top end of the tonic replenishing plate 16, it slides down to the bottom plate 1 under the action of gravity until it abuts against the existing medicine box on the bottom plate 1;

[0044] 3. When medicine needs to be taken out, drive the swing rod 8 to swing through the servo motor 12, so that the first baffle block 9 moves downward and the second baffle block 10 moves upward. After the lowermost medicine box loses the block of the first baffle block 9, it slides down to the lower conveyor belt 21 under the action of gravity, and the next medicine box to be taken out will not slide down under the action of the second baffle block 10, completing the taking out of one medicine box.

[0045] 4. Drive the swing rod to swing through the servo motor 12, move the first material blocking block 9 upward, and move the second material blocking block 10 downward. After the next medicine box to be discharged loses the block of the second material blocking block 10, it slides down under the action of gravity until it stops sliding after encountering the first material blocking block 9;

[0046] 5. Repeat steps 4 and 5 to discharge medicine.

[0047] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
