Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and particularly relates to an Internet of Things intelligent self-service medicine vending device. Background Art

[0002] The Internet of Things intelligent self-service medicine vending device is an automatic medicine vending machine based on the Internet of Things technology and combined with the mobile payment function. It has the advantages of automatically dispensing medicine, not requiring manual on-duty 24 hours a day, and only needing to regularly replace expired medicines or add medicines.

[0003] For example, the automatic medicine vending machine provided by the Chinese patent with the application number CN106327690 has several medicine storage units arranged on a medicine shelf. The medicine storage unit includes a medicine storage slot and a medicine blocking curtain. The medicine storage slot is arranged obliquely, including a bottom plate and two side baffles connected thereto. Guide grooves are provided on the inner walls of the two side baffles from top to bottom. The medicine blocking curtain is placed on the medicine storage slot along the guide grooves and can slide up and down along the guide grooves. The bottom plate, side baffles, and medicine blocking curtain form a receiving space for accommodating medicines. A traction plate protrudes from the upper end of the outer side of the medicine blocking curtain; a guide rail is provided along the arrangement direction of the medicine storage slots below the traction plate. A pulley group is provided on the guide rail, and a gear-rack mechanism is installed on the pulley group. The gear driving motor is drivingly connected to the gear of the gear-rack mechanism, thereby driving the rack to move linearly up and down. The vertical linear movement direction of the rack is consistent with the vertical sliding direction of the medicine blocking curtain. A fork for engaging with the traction plate is installed at the top of the rack; a synchronous belt is provided outside the guide rail, and the pulley group is connected to the synchronous belt, and the synchronous belt drives the pulley group to move linearly,

[0004] thereby driving the rack to move.

[0005] The above patent adopts the conventional inclined discharge of medicines and the method of taking medicines from top to bottom. There are also Internet of Things self-service medicine vending machines in the prior art that horizontally discharge medicines from bottom to top. Although both of the above two methods can achieve the function of self-service medicine vending based on the Internet of Things, the method of taking medicines from top to bottom will cause the medicines located above to always be sold earlier than the medicines located below. As a result, during the process of adding medicines, not only new medicines need to be put in, but also the unsold medicines need to be manually moved to the upper part to ensure that they are sold first, which causes great inconvenience for adding medicines. Summary of the Invention

[0006] To solve the above technical problems, the present invention proposes an Internet of Things intelligent self-service medicine vending device.

[0007] The technical solution of the present invention is realized as follows:

[0008] An Internet of Things intelligent self-service medicine vending device, comprising:

[0009] a chassis, and a medicine taking opening is laterally arranged on the front side surface of the chassis;

[0010] The storage cells are arranged in a matrix on the rear inner wall of the chassis. The top opening of the storage cell is an addition port. At the bottom of the front side of the storage cell, there is a medicine outlet for discharging the medicine at the bottommost layer. Inside the storage cell, there is a push plate for pushing the bottommost medicine from the rear to the front out of the medicine outlet.

[0011] The medicine receiving trough is arranged on the traveling trolley in a height - adjustable manner. The traveling trolley is arranged on the inner bottom wall of the chassis and can be displaced along the width direction of the chassis. The medicine receiving trough is aligned with one of the storage cells through the lifting movement and the displacement of the traveling trolley in the width direction of the chassis to receive the medicine pushed out of the medicine outlet.

[0012] The top height of the push plate does not exceed the top height of the bottommost medicine in the storage cell. At the bottom of the storage cell, there is a plate displacement structure for controlling the front - and - back displacement of the push plate, and on the medicine receiving trough, there is a plate driving structure that can drive the plate displacement structure to act through telescopic movement to control the front - and - back displacement of the push plate.

[0013] Further, on both sides of the push plate in its length direction, there is a plate displacement structure, and the two plate displacement structures are symmetrically distributed in the width direction of the storage cell. The plate displacement structure includes a connecting block, a steel wire rope, a winding wheel, a guide wheel, and a circular gear pair.

[0014] The connecting block is fixedly arranged at the bottom of the rear side of the push plate. A through - slot for the front - and - back displacement of the connecting block is opened at the bottom of the storage cell. The thickness of the push plate is not less than the distance between the front inner wall surface of the through - slot and the front surface of the storage cell. The bottom of the connecting block extends to the lower part of the storage cell after passing through the through - slot.

[0015] The winding wheel and the guide wheel are both rotatably installed at the bottom of the storage cell, and one guide wheel is arranged at each of the front and rear ends of the bottom of the storage cell. The steel wire rope is wound around the winding wheel, and the front end and the rear end of the steel wire rope respectively pass around the guide wheels in the corresponding directions and are fixed on the front surface and the rear surface of the connecting block.

[0016] The circular gear pair includes three circular gears that are meshed in sequence. One of the circular gears is coaxially fixed on the winding wheel, and the other two circular gears are both rotatably installed at the bottom of the storage cell.

[0017] Further, the plate driving structure includes an electric telescopic rod and a driving rack.

[0018] The electric telescopic rod is fixedly arranged at the bottom of the medicine receiving trough and is arranged perpendicular to the medicine outlet. The driving rack is fixedly arranged on the extending end of the electric telescopic rod, and tooth teeth are arranged on both side surfaces of the driving rack corresponding to the width direction of the storage cell.

[0019] The two plate displacement structures are spaced apart in the width direction at the bottom of the storage grid to form a channel for driving the rack to move back and forth. The three circular gears in the circular gear pair are arranged in sequence in the length direction of the storage grid, and when the driving rack moves back and forth in the channel, its two sides are simultaneously engaged with the two frontmost circular gears.

[0020] Further, a first medicine transferring structure and a second medicine transferring structure are further arranged in the storage grid, wherein:

[0021] The first medicine transferring structure corresponds to the bottommost medicine and is used to synchronously move the bottommost medicine from both sides in the width direction of the storage grid to the middle position so that the bottommost medicine is centered with the medicine outlet in the width direction;

[0022] The second medicine transferring structure corresponds to the remaining medicines above the bottommost medicine and is used to clamp and lift the remaining medicines from both sides in the width direction of the storage grid so that the remaining medicines are separated from the top of the bottommost medicine.

[0023] Further, the first medicine transferring structure includes a first medicine transferring plate, a rotary push block, a rotary shaft, a spiral groove, a groove slide rod and a medicine transferring driving plate, wherein:

[0024] Two first medicine transferring plates are slidably arranged in the storage grid and are symmetrically distributed. The top end of the rotary push block is rotatably installed on the side wall of the storage grid through the rotary shaft. When the bottom end of the rotary push block rotates inward, it drives the first medicine transferring plate to push the bottommost medicine;

[0025] The spiral groove is opened on the surface of the rotary shaft. The top end of the groove slide rod is slidably matched with the spiral groove, and the groove slide rod drives the bottom end of the rotary push block to rotate inward by moving backward along the axial direction of the rotary shaft in the spiral groove;

[0026] A groove for the displacement of the groove slide rod is opened on the side wall of the storage grid, and the bottom end of the groove slide rod penetrates through the groove and extends below the storage grid. The medicine transferring driving plate is slidably arranged at the bottom of the storage grid parallel to the width direction of the storage grid, and both ends of the medicine transferring driving plate are respectively fixed to the bottom ends of the two groove slide rods.

[0027] Further, a first arc surface is arranged at the bottom end of the rotary push block, and a first arc groove for the bottom end of the rotary push block to pass through is arranged at the top end of the outer side surface of the first medicine transferring plate;

[0028] The length of the rotary push block is set such that when it rotates inward by 90°, its bottom end is outside the medicine, and the rotary push block is set such that when it rotates inward by 90°, it is in a horizontal state and above the first medicine transferring plate;

[0029] A pull-back spring is arranged between the outer side surface of the first medicine-transferring plate and the inner side wall of the storage compartment. When the first medicine-transferring plate moves inward, the pull-back spring is stretched to provide an elastic force for the restoration of the first medicine-transferring plate.

[0030] When the first medicine-transferring plate is in the initial position, the distance between the two first medicine-transferring plates is greater than the width of the medicine. When the first medicine-transferring plate is pushed inward to the innermost position by the rotary push block, the distance between the two first medicine-transferring plates is adapted to the width of the medicine.

[0031] The first arc surface and the first arc groove are arranged such that when the rotary push block rotates outward from the state of rotating inward by 90°, the bottom end of the first arc surface enters its interior through the top notch of the first arc groove.

[0032] Further, the second medicine-transferring structure includes a second medicine-transferring plate, a limiting block, a second arc groove, a third arc groove, and a plate connection structure, wherein:

[0033] Two second medicine-transferring plates are provided and are respectively located on the tops of the two first medicine-transferring plates. The limiting block is fixedly arranged on the inner surface of the rotary push block, and a second arc surface centered on the rotation axis is arranged at the bottom of the limiting block. The second arc groove is arranged on the side surface of the second medicine-transferring plate, and a third arc groove penetrating through the bottom of the second medicine-transferring plate is arranged at the bottom of the second arc groove.

[0034] When the rotary push block is in the initial position, the circumference where the second arc surface is located is within the circumference range of the first arc groove.

[0035] When the rotary push block pushes the first medicine-transferring plate to the innermost position, the second arc groove and the second arc surface are coaxial, the top of the second arc surface is located in the second arc groove, and the second arc surface contacts the inner wall of the second arc groove.

[0036] When the bottom of the rotary push block rotates inward by 90° and the rotary push block is in a horizontal state, the third arc groove fits with the second arc surface.

[0037] The second medicine-transferring plate includes an inner plate body and an outer plate body distributed inside and outside. A guide rod vertically penetrating the outer plate body is fixedly arranged on the outer surface of the inner plate body, and a buffer spring is arranged between the guide rod and the outer plate body.

[0038] The plate connection structure is arranged between the first medicine-transferring plate and the second medicine-transferring plate.

[0039] Further, the plate connection structure includes a connecting plate, a first connection groove, a second connection groove, a connecting shaft, and a third connection groove, wherein:

[0040] The first connecting groove and the second connecting groove are respectively provided at the top of the first medicine moving plate and the bottom of the second medicine moving plate, and connecting shafts are provided on both sides of the top and bottom ends of the connecting plate, and the bottom end of the connecting plate is rotatably mounted in the first connecting groove through the connecting shaft, and the third connecting groove is provided on both sides of the second connecting groove and is adapted to the connecting shaft at the top end of the connecting plate;

[0041] When the second medicine moving plate is located on the top of the first medicine moving plate, the top end of the connecting plate is inserted into the second connecting groove, and when the second medicine moving plate is lifted up by the rotary push block, the top end of the connecting plate is displaced downward in the second connecting groove;

[0042] The inner side surface of the notch of the first connecting groove and the outer side surface of the notch of the second connecting groove are both configured as inclined surfaces.

[0043] Furthermore, a connecting rod is fixedly provided on the extended end of the electric telescopic rod, and the rear end of the connecting rod is provided with a rod sleeve with open ends, the driving rack is fixedly provided on the rear end of the connecting rod, and a force storage spring is provided between the front end of the rod sleeve and the extended end of the electric telescopic rod, and a through hole for driving the rack to enter the channel is provided on the medicine moving drive plate, and the size of the through hole is smaller than the rear end outer diameter of the rod sleeve.

[0044] Furthermore, a receiving groove for receiving the push plate is provided on the inner wall at the rear end of the storage compartment, and the three circular gears in the circular gear pair gradually decrease in size from front to back.

[0045] The present invention has the following beneficial effects:

[0046] 1. The drug storage and retrieval of the present invention follows the principle of top-in and bottom-out, which not only meets the demand for more convenient drug addition, but also can satisfy the requirement that the first added drugs are taken out from the storage compartment first during the automatic vending process to prevent the drugs from expiring. Compared with the prior art relying on manual inspection, it is more convenient and more in line with the requirements.

[0047] 2. In the process of taking medicine, when the medicine at the bottom is pushed out by the push plate, the other medicines are lifted up by the second medicine moving plate to a state of being away from the medicine at the bottom, which can prevent the medicines stacked in the storage compartment from interfering with each other, making it easier to take medicine. At the same time, the medicine at the bottom is centered in the width direction of the medicine outlet before taking medicine, which reduces the friction between the medicine at the bottom and the side wall of the storage compartment during the process of taking medicine, making it easier to take medicine.

Specific Embodiments

[0062] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0063] Please refer to Figures 1 to 13 As shown, the Internet of Things intelligent self-service medicine vending device provided by the embodiment of the present invention mainly includes a chassis 1, a storage grid 3, a traveling trolley, a medicine receiving groove 5, a plate displacement structure 6, and a plate driving structure 7. A medicine taking port 2 is laterally arranged on the front side of the chassis 1. The storage grid 3 is arranged in a matrix on the rear inner wall of the chassis 1. The top of the storage grid 3 is open as an addition port 3.1 for putting in medicines. A medicine outlet 3.2 for the bottommost medicine to exit is arranged at the bottom of the front side of the storage grid 3. Specifically, the medicine leaves the storage grid 3 through the medicine outlet 3.2. A push plate 4 is arranged inside the storage grid 3 to push the bottommost medicine from the back to the front out of the medicine outlet 3.2.

[0064] Specifically, the traveling trolley is arranged inside the chassis 1 and is arranged to be displaceable on the inner bottom wall of the chassis 1 in the width direction of the chassis 1 under the action of a control system to adjust the position of the medicine receiving groove 5 in the width direction of the chassis 1. The medicine receiving groove 5 is arranged on the traveling trolley to be liftable in the height direction. In this embodiment, a threaded rod is arranged on the top of the traveling trolley. The medicine receiving groove 5 is in threaded cooperation with the threaded rod. A stepping motor for driving the threaded rod to rotate is arranged on the top of the traveling trolley. The control system drives the screw rod to rotate forward or backward by controlling the positive and reverse rotation of the stepping motor to achieve the purpose of driving the height of the medicine receiving groove 5. Furthermore, by the displacement of the traveling trolley in cooperation with the operation of the stepping motor, the displacement of the medicine receiving groove 5 in the width direction and the height direction of the chassis 1 can be controlled, so that the rear end notch of the medicine receiving groove 5 is aligned with one of the storage grids 3. At this time, the bottommost medicine pushed out by the push plate 4 in the storage grid 3 will fall into the medicine receiving groove 5 after passing through the medicine outlet 3.2, realizing the medicine taking process. After taking the medicine, the medicine receiving groove 5 is displaced to the medicine outlet 3.2 through the cooperation of the traveling trolley and the stepping motor.

[0065] The medicine receiving groove 5 is arranged in an L-shaped plate shape, and a plurality of through notches are opened on its bottom plate. A conveyor belt is arranged at a position above the medicine outlet 3.2 in the chassis 1. Protrusions corresponding to the notches are arranged on the conveyor belt. When the medicine receiving groove 5 is displaced so that the protrusions pass through the notches and contact the medicine on the medicine receiving groove 5, the conveyor belt conveys the medicine on the medicine receiving groove to the medicine outlet 3.2.

[0066] The top height of the push plate 4 does not exceed the top height of the bottom medicine in the storage compartment 3. A plate displacement structure 6 for controlling the forward and backward displacement of the push plate 4 is provided at the bottom of the storage compartment 3, and a plate driving structure 7 is provided on the medicine receiving groove 5, which can drive the plate displacement structure 6 to move through telescopic movement to control the forward and backward displacement of the push plate 4.

[0067] In this embodiment, a plate displacement structure 6 is provided on both sides of the push plate 4 in the length direction, and the two plate displacement structures 6 are symmetrically distributed in the width direction of the storage compartment 3. The plate displacement structure 6 includes a connecting block 6.1, a wire rope 6.2, a winding wheel 6.3, a guide wheel 6.4 and a circular gear pair 6.5.

[0068] The connection block 6.1 is fixedly arranged at the bottom of the rear side of the push plate 4. A through slot 3.3 for the connection block 6.1 to move forward and backward is provided at the bottom of the storage compartment 3. The thickness of the push plate 4 is not less than the distance between the front inner wall of the through slot 3.3 and the front end of the storage compartment 3. When the connection block 6.1 moves to the front end of the through slot 3.3 and contacts the front inner wall of the through slot 3.3, the push plate 4 can make the medicine completely leave the storage compartment 3 from the medicine outlet 3.2. The bottom of the connection block 6.1 passes through the through slot 3.3 and extends to the bottom of the storage compartment 3.

[0069] The winding wheel 6.3 and the guide wheel 6.4 are both rotatably mounted on the bottom of the storage compartment 3, and one guide wheel 6.4 is provided at both the front and rear ends of the bottom of the storage compartment 3. The wire rope 6.2 is wound around the winding wheel 6.3, and the front and rear ends of the wire rope 6.2 are respectively fixed to the front and rear ends of the connecting block 6.1 after passing through the guide wheels 6.4 in the corresponding directions forward and backward.

[0070] The circular gear pair 6.5 comprises three circular gears meshing in sequence, one of which is coaxially fixed on the winding wheel 6.3, and the other two circular gears are rotatably mounted on the bottom of the storage compartment 3.

[0071] Specifically, after the front end of the wire rope 6.2 extends forward, it passes backward around its corresponding guide wheel 6.4 and is fixed on the front side of the connecting block 6.1. After the rear end of the wire rope 6.2 extends backward, it passes backward around its corresponding guide wheel 6.4 and is fixed on the rear side of the connecting block 6.1.

[0072] At this time, when the steel wire rope 6.2 rotates and drives the connecting block 6.1 to move forward in the through groove 3.3, the connecting block 6.1 drives the push plate 4 to move forward. At this time, the push plate 4 pushes the medicine out of the medicine outlet 3.2.

[0073] The plate driving structure 7 comprises an electric telescopic rod 7.1 and a driving rack 7.2.

[0074] The electric telescopic rod 7.1 is fixedly arranged at the bottom of the medicine receiving groove 5 and is set to be perpendicular to the medicine outlet 3.2. The driving rack 7.2 is fixedly arranged at the extending end of the electric telescopic rod 7.1, and teeth are arranged on both sides of the driving rack 7.2 corresponding to the width direction of the storage grid 3.

[0075] The two plate displacement structures 6 are spaced apart in the width direction at the bottom of the storage grid 3 to form a channel 8 for the forward and backward displacement of the driving rack 7.2. The three circular gears in the circular gear pair 6.5 are arranged in sequence in the length direction of the storage grid 3, and when the driving rack 7.2 moves forward and backward in the channel 8, its two sides are simultaneously engaged with the two frontmost circular gears.

[0076] At this time, after the medicine receiving groove 5 is aligned with one of the storage grids 3, during the extension of the extending end of the electric telescopic rod 7.1, it enters below the storage grid 3 and makes the driving rack 7.2 enter the channel 8, and the driving rack 7.2 synchronously drives the two circular gear pairs 6.5 to act. Furthermore, when the two winding shafts rotate, they respectively drive the two steel wire ropes 6.2 to perform a rotary motion, and the steel wire ropes 6.2 drive the push plate 4 through the connecting block 6.1 to push the bottommost medicine out of the discharge port; similarly, when the extending end of the electric telescopic rod 7.1 retracts, the driving rack 7.2 synchronously drives the two circular gear pairs 6.5 to act. At this time, the two winding shafts rotate in the reverse direction and make the push plate 4 return to the initial position through the steel wire ropes 6.2 and the connecting block 6.1.

[0077] In this embodiment, a first medicine transferring structure 9 and a second medicine transferring structure 10 are further arranged in the storage grid 3, where:

[0078] The first medicine transferring structure 9 corresponds to the bottommost medicine and is used to synchronously move the bottommost medicine from both sides in the width direction of the storage grid 3 to the middle position, and make the bottommost medicine be centered with the medicine outlet 3.2 in the width direction. At this time, the bottommost medicine is centered before the push plate 4 pushes the bottommost medicine out, so that during the process of the push plate 4 pushing the bottommost medicine out, the two sides of the bottommost medicine do not contact the inner walls of both sides of the storage grid 3, which is more convenient for taking medicine.

[0079] The second medicine transferring structure 10 corresponds to the remaining medicines above the bottommost medicine and is used to clamp and lift the remaining medicines from both sides in the width direction of the storage grid 3 so that the remaining medicines are separated from the top of the bottommost medicine. At this time, before the push plate 4 pushes the bottommost medicine out, the remaining medicines above the bottommost medicine are all lifted by the second medicine transferring structure 10 to a state separated from the bottommost medicine, avoiding interfering with the displacement of the bottommost medicine and being more convenient for taking medicine.

[0080] Among them, the first medicine transferring structure 9 includes a first medicine transferring plate 9.1, a rotary push block 9.2, a rotary shaft 9.3, a spiral groove 9.4, a groove slide rod 9.5 and a medicine transferring driving plate 9.6.

[0081] There are two first medicine transfer plates 9.1 slidably arranged in the storage cell 3 and symmetrically distributed. The top end of the rotary push block 9.2 is rotatably installed on the side wall of the storage cell 3 through a rotary shaft 9.3. When the bottom end of the rotary push block 9.2 rotates inward, it drives the first medicine transfer plate 9.1 to push the bottommost medicine. At this time, in the initial state, the rotary push block 9.2 is in a state of being received in the side wall of the storage cell 3, and the rotary push block 9.2 is in a vertical state.

[0082] A spiral groove 9.4 is formed on the surface of the rotary shaft 9.3. The top end of the groove slide rod 9.5 is located in the spiral groove 9.4 and is slidably matched with the spiral groove 9.4. And the groove slide rod 9.5 drives the bottom end of the rotary push block 9.2 to rotate inward by axially displacing backward along the rotary shaft 9.3 in the spiral groove 9.4.

[0083] A groove 3.4 for the displacement of the groove slide rod 9.5 is formed on the side wall of the storage cell 3. And the bottom end of the groove slide rod 9.5 penetrates through the groove 3.4 and extends below the storage cell 3. The medicine transfer driving plate 9.6 is slidably arranged at the bottom of the storage cell 3 parallel to the width direction of the storage cell 3, and both ends of the medicine transfer driving plate 9.6 are respectively fixed to the bottom ends of the two groove slide rods 9.5.

[0084] At this time, when the medicine transfer driving plate 9.6 is forced to translate backward, it drives the groove slide rod 9.5 to displace backward. The groove slide rod 9.5 drives the rotary shaft 9.3 to rotate through the spiral groove 9.4, and further drives the bottom end of the rotary push block 9.2 to rotate inward, achieving the effect that the rotary push block 9.2 pushes the first medicine transfer plate 9.1 inward.

[0085] Further, a first arc surface 9.21 is provided at the bottom end of the rotary push block 9.2, and a first arc groove 9.11 for the bottom end of the rotary push block 9.2 to pass through is provided at the top end of the outer side surface of the first medicine transfer plate 9.1. The length of the rotary push block 9.2 is set such that when the rotary push block 9.2 rotates inward by 90°, the bottom end of the rotary plate is outside the medicine, and the rotary push block 9.2 is set such that when its bottom end rotates inward by 90°, it is in a horizontal state and above the first medicine transfer plate 9.1. When the rotary push block 9.2 is in the initial state, the height of its bottom end is less than the height of the first arc groove 9.11.

[0086] Specifically, when the bottom end of the rotary push block 9.2 rotates inward, it first contacts the part of the outer side surface of the first medicine transfer plate 9.1 below the first arc groove 9.11 and pushes the first medicine transfer plate 9.1 inward.

[0087] A return spring 9.7 is arranged between the outer side surface of the first medicine transfer plate 9.1 and the inner side wall of the storage cell 3. When the first medicine transfer plate 9.1 displaces inward, the return spring 9.7 is stretched, providing an elastic force for the first medicine transfer plate 9.1 to return outward to the initial position.

[0088] Specifically, during the process of pushing the first medicine transfer plate 9.1 inward at the bottom end of the rotary pushing block 9.2, the bottom end of the rotary pushing block 9.2 will enter the first arc-shaped groove 9.11.

[0089] In this embodiment, when the bottom end of the inner side surface of the rotary pushing block 9.2 contacts the bottom end of the notch of the first arc-shaped groove 9.11, the bottom edge of the notch of the first arc-shaped groove 9.11 coincides with the position where the circumference of the first arc-shaped groove 9.11 is tangent to the circumference of the bottom of the inner side surface of the rotary pushing block 9.2, and the part of the circumference where the bottom end of the inner side surface of the rotary pushing block 9.2 is located outside this tangent position is within the circumference of the inner wall of the first arc-shaped groove 9.11 in this state. At this time, during the continuous rotation process after the bottom end of the inner side surface of the rotary pushing block 9.2 enters the first arc-shaped groove 9.11, a gap is formed between the rotary pushing block 9.2 and the first medicine transfer plate 9.1 for the first medicine transfer plate 9.1 to displace outward and recover under the action of the return spring 9.7. When the first medicine transfer plate 9.1 rotates inward by 90°, since it is located above the first medicine transfer plate 9.1, there is space for the rotary pushing block 9.2 to return to its initial position under the action of the return spring 9.7.

[0090] In this embodiment, by setting the displacement distance of the first medicine transfer plate 9.1 in cooperation with the width of the medicine, when the first medicine transfer plate 9.1 is in the initial position, the distance between the two first medicine transfer plates 9.1 is greater than the width of the medicine. After such a setting, it is more convenient to add the medicine. When the first medicine transfer plate 9.1 is pushed inward to the innermost position by the rotary pushing block 9.2, the distance between the two first medicine transfer plates 9.1 is adapted to the width of the medicine. After such a setting, the first medicine transfer plate 9.1 can be used to move the medicine to a state where it is centered with the discharge port.

[0091] Furthermore, the first arc-shaped surface 9.21 and the first arc-shaped groove 9.11 are set such that when the rotary pushing block 9.2 rotates outward and recovers from the state of rotating inward by 90°, the bottom end of the first arc-shaped surface 9.21 enters its interior through the top notch of the first arc-shaped groove 9.11. In this way, the restored first medicine transfer plate 9.1 will not hinder the recovery of the rotary pushing block 9.2.

[0092] In this embodiment, the second medicine transfer structure 10 includes a second medicine transfer plate 10.1, a limiting block 10.2, a second arc-shaped groove 10.3, a third arc-shaped groove 10.4, and a plate connection structure 10.5, where:

[0093] There are two second medicine transfer plates 10.1, and the two second medicine transfer plates 10.1 are respectively located on the tops of the two first medicine transfer plates 9.1. The limiting block 10.2 is fixedly arranged on the inner surface of the rotary push block 9.2, and the limiting block 10.2 is arranged in a fan-shaped structure, and a second arc surface 10.21 with the rotary shaft 9.3 as the axis is arranged at its bottom.

[0094] The second arc groove 10.3 is arranged on the side surface of the second medicine transfer plate 10.1, and a third arc groove 10.4 penetrating through the bottom of the second medicine transfer plate 10.1 is arranged at the bottom of the second arc groove 10.3.

[0095] Further, when the rotary push block 9.2 is in the initial position, the circumference where the second arc surface 10.21 is located is within the circumference range of the first arc groove 9.11.

[0096] When the rotary push block 9.2 pushes the first medicine transfer plate 9.1 inward to the innermost position, the second arc groove 10.3 and the second arc surface 10.21 are in a coaxial state, and the top end of the second arc surface 10.21 is located in the second arc groove 10.3, and the second arc surface 10.21 contacts the inner wall of the second arc groove 10.3.

[0097] When the bottom of the rotary push block 9.2 rotates inward by 90° and the rotary push block 9.2 is in a horizontal state, the third arc groove 10.4 fits on the second arc surface 10.21.

[0098] The second medicine transfer plate 10.1 includes an inner plate body 10.11 and an outer plate body 10.12 which are distributed inside and outside. A guide rod 10.13 vertically penetrating the outer plate body 10.12 is fixedly arranged on the outer surface of the inner plate body 10.11, and a buffer spring 10.14 is arranged between the guide rod 10.13 and the outer plate body 10.12.

[0099] Specifically, in the process of the bottom end of the rotary push block 9.2 rotating inward, there are the following processes:

[0100] Firstly, when the bottom of the inner side surface of the rotary push block 9.2 rotates from the vertical state to contact the bottom of the notch of the first arc groove 9.11, the first medicine transfer plate 9.1 is pushed inward to the innermost position, and at this time, the top of the second arc surface 10.21 enters into the second arc groove 10.3 and contacts the inner wall surface of the second arc groove 10.3. So that the second arc surface 10.21 has a limiting effect on the outside of the second medicine transfer plate 10.1.

[0101] Second, during the continuous rotation of the rotary pushing block 9.2, the bottom of the inner side surface of the rotary pushing block 9.2 will enter the first arc-shaped groove 9.11. At this time, since the circumference where the bottom of the inner side surface of the rotary pushing block 9.2 is located is tangent to the circumference where the first arc-shaped groove 9.11 is located at the bottom end of the socket of the first arc-shaped groove 9.11, and the circumference where the bottom of the inner side surface of the rotary pushing block 9.2 is located is inside the circumference where the first arc-shaped groove 9.11 is located in this state. Therefore, when the bottom of the rotary pushing block 9.2 rotates into the first arc-shaped groove 9.11, it provides a displacement space for the first medicine transfer plate 9.1 to displace outward. And because the second arc-shaped surface 10.21 is in contact with the inner wall surface of the second arc-shaped groove 10.3, it can prevent the second medicine transfer plate 10.1 from displacing outward.

[0102] Third, from the moment when the inner surface of the rotary pushing block 9.2 rotates upward until it touches the bottom of the second medicine transfer plate 10.1 until the bottom of the rotary pushing block 9.2 rotates inward by 90°, the outer plate body 10.12 has the function of displacing inward and stretching the buffer spring 10.14. At this time, during the process of the second medicine transfer plate 10.1 lifting the medicine, the clamping force of the second medicine transfer plate 10.1 on the medicine is continuously increased.

[0103] The plate connection structure 10.5 is arranged between the first medicine transfer plate 9.1 and the second medicine transfer plate 10.1.

[0104] Specifically, in this embodiment, the plate connection structure 10.5 includes a connection plate 10.51, a first connection groove 10.52, a second connection groove 10.53, a connection shaft 10.54, and a third connection groove 10.55, where:

[0105] The first connection groove 10.52 and the second connection groove 10.53 are respectively opened at the top of the first medicine transfer plate 9.1 and the bottom of the second medicine transfer plate 10.1. Connection shafts 10.54 are arranged on both sides of the top and bottom ends of the connection plate 10.51. The bottom end of the connection plate 10.51 is rotatably installed in the first connection groove 10.52 through the connection shaft 10.54. The third connection groove 10.55 is opened on both sides of the second connection groove 10.53 and is adapted to the connection shaft 10.54 at the top end of the connection plate 10.51.

[0106] In the initial state, when the second medicine transfer plate 10.1 is located at the top of the first medicine transfer plate 9.1, the top end of the connection plate 10.51 is in a state of being inserted into the second connection groove 10.53. At this time, the connection plate 10.51 has the function of keeping the first medicine transfer plate 9.1 and the second medicine transfer plate 10.1 relatively stationary in the inner and outer directions. Furthermore, when the rotary pushing block 9.2 pushes the first medicine transfer plate 9.1 inward, the second medicine transfer plate 10.1 synchronously displaces inward, so as to achieve the effect that the first medicine transfer plate 9.1 clamps the bottommost medicine while the second medicine transfer plate 10.1 clamps the remaining medicines.

[0107] When the inner side of the rotary push block 9.2 contacts the bottom of the second medicine moving plate 10.1 and continues to rotate, the rotary push block 9.2 will lift the medicine moving plate. At this time, the top of the connecting plate 10.51 moves downward in the second connecting groove 10.53, and the connecting shaft 10.54 at the top of the connecting plate 10.51 moves downward in the third connecting groove 10.55.

[0108] The inner side surface of the slot of the first connecting groove 10.52 and the outer side surface of the slot of the second connecting groove 10.53 are both set to inclined surfaces. At this time, when the connecting shaft 10.54 moves to the bottom end of the third connecting groove 10.55, the first medicine moving plate 9.1 is restored to its initial position outward under the action of the return spring 9.7, and the connecting plate 10.51 is tilted so that the top of its outer side surface contacts the inclined surface on the slot of the second connecting groove 10.53. At the same time, the bottom of the inner side surface of the connecting plate 10.51 contacts the inclined surface on the slot of the first connecting groove 10.52, and the second connecting plate 10.51 is attached to the second curved surface 10.21 through the third arc groove 10.4, the top of the outer side surface of the connecting plate 10.51 contacts the inclined surface on the slot of the second connecting groove 10.53, and the limiting effect of the medicine from the inside to the outside keeps it in a vertical state and a state of clamping the medicine.

[0109] The following process occurs during the reverse rotation recovery of the rotary push block 9.2:

[0110] First, before the second arc surface 10.21 enters the first arc groove 9.11 from the top notch thereof, during the process of the bottom end of the rotary push block 9.2 rotating downward, the first medicine moving plate 9.1 is located at the initial position.

[0111] Secondly, when the second arc surface 10.21 enters the interior of the first arc groove 9.11 from the top notch of the first arc groove 9.11 and continues to move outward, the rotary push block 9.2 causes the first medicine moving plate 9.1 to move inward again, and when the bottom end of the rotary push block 9.2 leaves the bottom notch of the first arc groove 9.11, under the action of the buffer spring 10.14, the connecting plate 10.51 is in a vertical state, and the second medicine moving plate 10.1 falls downward and gradually returns to the state of falling on the top of the first medicine moving plate 9.1.

[0112] Furthermore, in the present embodiment, a connecting rod 11 is fixedly provided on the extended end of the electric telescopic rod 7.1, a rear end of the connecting rod 11 is sleeved with a rod sleeve 12 with both ends being open, a driving rack 7.2 is fixedly provided on the rear end of the connecting rod 11, a force storage spring 13 is provided between the front end of the rod sleeve 12 and the extended end of the electric telescopic rod 7.1, a through hole 14 for driving the rack 7.2 to enter the channel 8 is provided on the medicine moving drive plate 9.6, and the size of the through hole 14 is smaller than the outer diameter of the rear end of the rod sleeve 12.

[0113] Specifically, during the process of the extending end of the electric telescopic rod 7.1 extending towards the bottom of the storage compartment 3, under the elastic action of the energy storage spring 13, the rear end of the rod sleeve 12 drives the groove slide rod 9.5 to displace by pushing the medicine transfer driving plate 9.6, so as to drive the bottom end of the rotary push block 9.2 to rotate inwards by 90°. And during this process, the first medicine transfer plate 9.1 releases the bottommost medicine after aligning the bottommost medicine to the middle, and the second medicine transfer plate 10.1 lifts the remaining medicines after clamping them to separate them from the top of the bottommost medicine.

[0114] During the subsequent extending process of the extending end of the electric telescopic rod 7.1, since the top end of the groove slide rod 9.5 enters the inner end of the spiral groove 9.4 after the rotary push block 9.2 rotates by 90°, therefore, the medicine transfer driving plate 9.6 no longer moves backward. At this time, the energy storage spring 13 will be compressed, and the rear end of the connecting rod 11 continuously inserts into the rod sleeve 12, and the driving rack 7.2 extends from the rear end of the rod sleeve 12 and enters the channel 8 through the through hole 14 to drive the push plate 4 to push the bottommost medicine out of the medicine outlet 3.2, completing the medicine discharging process.

[0115] Among them, a receiving groove 15 for accommodating the push plate 4 is provided on the inner wall surface of the rear end of the storage compartment 3. In the initial state, the push plate 4 is located in the receiving groove 15, so as to facilitate adding medicines into the storage compartment 3 from the adding port 3.1. At the same time, the three circular gears in the circular gear pair 6.5 gradually decrease in size from front to back. In this way, the circular gear pair 6.5 has an acceleration process along the output direction, which can shorten the displacement distance of the driving rack 7.2.

[0116] After applying the above solution of the present invention, on the one hand, the medicine storage and retrieval of the present invention follow the principle of upper-in and lower-out. It not only meets the requirement of more convenient medicine addition, but also can ensure that the medicines added first are taken out from the storage compartment 3 first during the automatic vending process to prevent medicine expiration. Compared with the prior art that relies on manual judgment, it is more convenient and more in line with requirements.

[0117] On the other hand, during the medicine taking process of the present invention, when the bottommost medicine is pushed out by the push plate 4, the remaining medicines are lifted by the second medicine transfer plate 10.1 to a state of separating from the bottommost medicine, which can prevent the medicines stacked in the storage compartment 3 from interfering with each other and is more convenient for taking medicines. At the same time, the bottommost medicine is aligned in the width direction of the medicine outlet 3.2 before taking the medicine, reducing the friction between the bottommost medicine and the side wall of the storage compartment 3 during the medicine taking process, and is more convenient for taking medicines.

[0118] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
