[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0023] Such as Figure 1-2As shown, the medicine dispensing device for an automatic medicine dispensing machine of the embodiment of the utility model comprises a layer plate 1, a slideway 2, a steering gear 5 and a blocking plate 7. The slideway 2 is arranged on the upper side of the layer plate 1, the front end of the slideway 2 is higher than the rear end, and the layer plate 1 is arranged parallel to the slideway 2; the layer plate 1 has an installation cavity, the steering gear 5 and the blocking plate 7 are arranged in the installation cavity, the blocking plate 7 is located at the rear end of the slideway 2, the rear end of the blocking plate 7 has an upward hook plate, and the layer plate 1 has a notch corresponding to the hook plate; the steering gear arm 9 of the steering gear 5 is connected to the front end of the blocking plate 7 by transmission, and the steering gear arm 9 drives the blocking plate 7 to rotate when swinging, so that the hook plate swings up and down, and the hook plate can fall into the installation cavity when swinging downward, and can extend out of the notch when swinging upward to block the medicine box 3 sliding down the slideway 2. Among them, the front end is one end in the direction of medicine inflow, and the rear end is one end in the direction of medicine outflow.

[0024] The medicine dispensing device for an automatic medicine dispensing machine of the embodiment of the utility model can be used in conjunction with the automatic medicine dispensing machine. The medicine dispensing device is installed at the end of the slideway of the automatic medicine dispensing machine so that the front end of the slideway 2 docks with the end of the slideway, and the medicine box 3 that slides down the slideway can be drawn into the slideway 2. In the medicine dispensing device, the layer plate 1 is the main body installation support mechanism, the slideway 2 is parallel to the layer plate 1, and maintains a certain inclination angle (the front end is higher than the end / rear end), which can facilitate the medicine box 3 that slides out of the automatic medicine dispensing machine to slide down the slideway 2 smoothly. During the sliding down of the medicine box, the servo arm 9 swings continuously or at intervals to make the hook plate of the blocking plate 7 swing up and down. When the hook plate swings up, it can block the medicine box 3 from sliding down; when the hook plate swings down, the medicine box 3 loses the blockage and can slide down smoothly. By controlling the swing frequency, swing amplitude, holding time, etc. of the servo arm 9, medicine boxes of different specifications can be accurately dropped.

[0025] In an optional embodiment, a tray box is provided below the layer plate 1, forming a mounting cavity with the layer plate 1, a frame 4 is provided in the mounting cavity, and a steering gear 5 and a blocking plate 7 are provided on the frame 4. The frame 4 (or the bottom plate of the tray box) is provided in parallel with the layer plate 1 and the slideway 2, that is, the medicine dispensing device is tilted as a whole.

[0026] like Figure 3 As shown, a through hole is provided in the middle of the blocking plate 7, and a steel shaft 10 is passed through the through hole. Axle holes are provided at the two ends of the corresponding steel shaft 10 on the frame 4, and the two ends of the steel shaft 10 match the axial holes and can be passed through the axial holes. Here, the two ends of the steel shaft 10 can rotate in the axial holes, and / or the steel shaft 10 can rotate in the axial holes, so that the blocking plate 7 can rotate around the steel shaft 10 in the middle. The servo arm 9 is connected with a cylindrical pin 11 extending vertically outward, and a long groove is provided at the front end of the blocking plate 7, and the cylindrical pin 11 extends into the long groove. Here, one end of the cylindrical pin 11 can be installed in the screw hole at the tail of the servo arm 9 by bolt connection, and the other end is inserted into the long groove. When the servo arm 9 swings, it drives the cylindrical pin 11 to slide in the long groove, so that the blocking plate 7 rotates around the steel shaft 10, driving the hook plate to swing up and down.

[0027] Optionally, the through hole in the middle of the baffle 7 is bent downward at a certain angle, which facilitates hiding the front plate part of the baffle 7 and the servo 5 in the installation cavity, and enables the hook plate at the end of the baffle 7 to swing out of the laminate 1. Moreover, the width of the front plate part of the baffle 7 is smaller than that of the rear plate part, which is convenient for installing the servo 5 in a limited space. It can optimize the structure and reduce the occupied space while ensuring that the servo 5 can smoothly drive the baffle 7 to swing.

[0028] Preferably, the initial position of the servo arm 9 is at the lowest end of the swing trajectory, the cylindrical pin 11 is at the rearmost end of the long slot, the baffle 7 is lifted to swing the hook plate to the highest position, and the center line of the cylindrical pin 11 is perpendicular to the connection line between the cylindrical pin 11 and the steel shaft 10 (that is, the cylindrical pin 11 is perpendicular to the length direction of the long slot). It can use the cylindrical pin 11 to block the baffle 7 at the dead point of rotation, so that when the baffle 7 is rotated by an external force, it will not push the servo arm 9 to rotate in the reverse direction, enabling the baffle 7 to withstand a large external force, that is, it can be applied to heavier drugs.

[0029] In this embodiment, a circuit board 6 for controlling the servo 5 is provided at the front end of the frame 4. The circuit board 6 is electrically connected to the servo 5 and also to the control system of the automatic medicine dispenser. It is used to receive instructions from the control system and send rotation instructions to the servo 5 to swing the servo arm 9. A servo control program is pre-integrated in the circuit board 6, which can adjust the swing speed, swing interval time, etc. of the servo arm 9 according to the length of the medicine box 3, and can accurately stop the next medicine box 3 after the medicine box 3 slides down, and is applicable to medicine boxes 3 of different lengths.

[0030] Moreover, a photoelectric detection element 8 is provided at the front end of the frame 4, a detection port is opened on the laminate 1 corresponding to the photoelectric detection element 8, and the detection direction of the photoelectric detection element 8 can be perpendicular to the surface of the laminate 1, which can detect the sliding medicine box 3 and determine that one-time medicine delivery is completed. The photoelectric detection element 8 can include a detection photoelectric board and a photoelectric switch.

[0031] According to an exemplary embodiment of the present invention, when the medicine delivery device for the automatic medicine dispenser is in use, the medicine delivery device is installed at the end of the medicine delivery chute of the automatic medicine dispenser. The medicine box 3 sliding out of the chute falls into the slideway 2 and is arranged on the inclined slideway. Due to the action of gravity, the medicine box 3 has a tendency to slide downward, but will be blocked by the baffle 7. When medicine needs to be delivered, the control system of the automatic medicine dispenser sends an instruction to the circuit board 6. The circuit board 6 controls the servo to rotate to swing the servo arm 9, thereby driving the baffle 7 to rotate and driving the hook plate to swing downward. After the medicine box 3 loses the block, it slides downward and falls. The circuit board 6 controls the servo 5 to reset according to the length of the medicine box 3, and the hook plate swings upward to block the subsequent medicine box 3 from continuing to slide, completing the medicine delivery of one box of medicine. The falling medicine box 3 will be detected by the photoelectric detection element 8 to ensure that the medicine delivery is completed.

[0032] In actual application scenarios, components such as the laminate 1, the blocking plate 7, the frame 4, the steel shaft 10, and the cylindrical pin 11 in the medicine dispensing device of the embodiment of the present utility model can be designed with corresponding structures and dimensions according to information such as the medicine dispensing specifications to be dispensed. Components such as the servo motor, the photoelectric detection element 8, and the circuit board 6 can adopt devices with corresponding functions and specifications in the prior art. For example, a servo-type electric servo motor is adopted for the servo motor, which can accurately and stably realize the swing of the servo arm 9.

[0033] In addition, other devices or components can also be provided in the medicine dispensing device for the automatic medicine dispenser, or the actual installation positions of the various devices or components can be adjusted to realize the actual application or other functions of the medicine dispensing device for the automatic medicine dispenser. For example, a communication component is further included, which is used to associate the control system of the automatic medicine dispenser with the servo control circuit board 6, the photoelectric detection element 8, etc. in the medicine dispensing device.

[0034] It should be noted that according to the needs of implementation, each component described in the embodiment of the present utility model can be split into more components, or two or more components or parts of the components can be combined into a new component to achieve the purpose of the embodiment of the present utility model.

[0035] The above embodiments only represent several implementation manners of the present utility model, and the description thereof is relatively specific and detailed, but it should not be understood as a limitation to the scope of the patent of the present utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the patent of the present utility model shall be subject to the appended claims.
