Description

Technical Field

[0001] This invention relates to the field of automatic dispensing machine technology, specifically to an intelligent dispensing machine. Background Technology

[0002] However, most automated dispensing machines currently use a method where medications fall from a height onto a conveyor belt and are then transported out. This method can cause damage to plastic or glass bottles containing medications due to the fall. Furthermore, most automated dispensing machines lack a diversion function, which can lead to medications from different patients being mixed together when nurses are unable to collect them in time, potentially causing medical accidents. To address these issues, this invention provides an intelligent dispensing machine. Summary of the Invention

[0003] The purpose of this invention is to provide an intelligent dispensing machine to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an intelligent dispensing machine, comprising two symmetrically arranged storage cabinets with their outlets close to each other. Each storage cabinet has multiple medicine storage tracks installed inside, and each track has a lifting plate at its lower opening for controlling the dispensing of medicine. The lifting plate controls the dropping of medicine from the storage tracks. Protective covers are fitted over the two storage cabinets, and a vertically movable medicine receiving frame is installed between them. During descent, the receiving frame collects medicine layer by layer from top to bottom, reducing the drop height and preventing damage. The receiving frame is a rectangular frame with open sides. The inside of the medicine receiving frame is symmetrically equipped with medicine receiving conveyor belts that are higher on the outside and lower on the inside. The lower ends of the two medicine receiving conveyor belts can be controlled to open and close to allow the medicine to fall. When the medicine receiving frame moves to the bottom, the lower ends of the two medicine receiving conveyor belts will separate from each other, and the medicine receiving conveyor belts will start to make the medicine fall from the inside of the medicine receiving frame. Below the medicine receiving frame and located between the two storage cabinets, a medicine dispensing conveyor belt is installed. One end of the medicine dispensing conveyor belt extends to the outside of the protective cover through a through-hole. The medicine that falls from the inside of the medicine receiving frame will fall onto the medicine dispensing conveyor belt and be sent out by the medicine dispensing conveyor belt for easy access by medical staff. A medicine loading frame for replenishing medicines is installed on one side of the protective cover.

[0005] Preferably, both ends of the belt shafts of the two drug receiving conveyor belts that are close to each other are rotatably connected to connecting rods, and the upper ends of the two connecting rods located at the same end are hinged to the corresponding sliding frames. The sliding frames are slidably connected in the sliding grooves opened on the inner side of the drug receiving frame and are fixedly connected to the output rod of the drug dispensing electric push rod installed inside the sliding grooves. The opening and closing of the lower ends of the two drug receiving conveyor belts can be controlled by controlling the extension and retraction of the output rod of the drug dispensing electric push rod.

[0006] Preferably, both belt shafts of the medicine receiving conveyor belt have annular grooves. A collar is rotatably connected inside each groove. A first fixing rod is fixedly connected to one collar, and a second fixing rod is fixedly connected to the other collar. An insert rod is fixedly connected to the end face of the second fixing rod near the first fixing rod. One end of the insert rod is inserted into a slot on the first fixing rod and connected to the bottom sidewall of the slot via a spring. The spring, through the first and second fixing rods, tends to move the two belt shafts of the medicine receiving conveyor belt away from each other, keeping the conveyor belt taut and ensuring stable transport.

[0007] Preferably, one end of the dispensing conveyor belt located outside the protective cover is installed inside the fixed base, and the fixed base is fixedly connected to the protective cover. Mounting plates are symmetrically fixedly connected to the inner side wall of the fixed base. A guide plate is hinged to the outer end of the mounting plate, and the guide plate is driven by a corresponding guide motor. The guide motor is mounted on the corresponding mounting plate. The guide plate can rotate at different angles to allow the medicines of different patients to fall to different positions, thus avoiding the mixing of medicines of different patients.

[0008] Preferably, both the mounting plate and the guide plate have grooves on their inner sides. The grooves are rotatably connected to multiple guide shafts via multiple mounting shafts located between their two side walls. The guide shafts allow the medicine to move better with the angle of the fixed seat and the guide plate.

[0009] Preferably, the medicine loading frame includes a horizontal medicine pushing frame and an inclined medicine dispensing frame. The protective cover and storage cabinet have through openings adapted to the medicine pushing frame. The height of the end of the medicine dispensing frame away from the medicine pushing frame is higher than the height of the other end, and a stop door is inserted inside the end of the medicine dispensing frame away from the medicine pushing frame. The medicine to be replenished is placed inside the medicine dispensing frame, and then the medicine inside the medicine dispensing frame slides into the medicine pushing frame and comes into contact with the medicine pushing conveyor belt on the push plate. A push plate is slidably connected inside the medicine pushing frame, and a medicine pushing conveyor belt is installed on the inner side of the push plate. A medicine loading conveyor belt is installed inside the storage cabinet and at the outer end of the medicine storage track. The medicine pushing conveyor belt transports the medicine in contact with it to the medicine loading conveyor belt. A push rod for pushing medicine is installed at the outer end of each medicine storage track and at the outer side wall of the storage cabinet. The push rod is controlled by a medicine loading electric push rod installed on the storage cabinet. When the medicine loading conveyor belt aligns the medicine with the corresponding medicine storage track, the push rod will activate to push the medicine into the corresponding medicine storage track to complete the medicine replenishment.

[0010] Preferably, a partition is fixedly connected to the outer side of the push plate, and a clearance groove adapted to the partition is opened on the protective cover, so that the partition can better protect the medicines inside the storage cabinet.

[0011] Preferably, a slider is fixedly connected to the outer end face of the push plate. The slider extends into a groove on the inner side wall of the medicine loading frame and is fixedly connected to the output rod of the electric push rod. The electric push rod is installed inside the groove and controls the position of the push plate inside the medicine loading frame by controlling the extension and retraction of the output rod of the electric push rod.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention, through the cooperation between the medicine receiving frame and the medicine receiving conveyor belt, enables the medicine receiving frame to squeeze different first touch switches during the up and down sliding process, thereby enabling the medicine storage track in the same row as the first touch switch to dispense medicine, which greatly reduces the height from which the medicine falls, thus avoiding damage to the plastic or glass bottles storing medicine due to excessive falling height; Through the cooperation between the mounting plate and the guide plate, the medicines of different patients can be diverted by controlling the rotation angle of the guide plate, which can effectively prevent the medicines of different patients from being mixed together.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figure 1-10This invention provides a technical solution: an intelligent dispensing machine, comprising two symmetrically arranged storage cabinets 1 with their outlets close to each other. Multiple medicine storage tracks 2 are installed inside each storage cabinet 1, arranged neatly in multiple rows and columns. A lifting plate 3 for controlling dispensing is installed at the lower opening of each medicine storage track 2. The end of each medicine storage track 2 near the outlet of the storage cabinet 1 is higher than the other end. When medicine is inside the medicine storage track 2, it slides towards the outlet of the storage cabinet 1. The lifting plate 3 can block the medicine, preventing it from falling from the medicine storage pipe 2. When the lifting plate 3 descends and no longer blocks the medicine, it can fall from inside the medicine storage track 2. The lifting plate 3 passes through the medicine storage track 2 and is installed with... The output rod of the electric push rod 37 for dispensing medicine is fixedly connected to the lower side of the medicine storage track 2. The lifting plate 3 is raised and lowered by controlling the extension and retraction of the output rod of the electric push rod 37. When retrieving medicine, medical staff input the medicine to be retrieved through the operating terminal (such as an external computer). The computer sends the data to the control module 45 installed on the protective cover 4 through the data cable. The control module 45 will control the output rod of the corresponding electric push rod 37 to retract and extend once, so that the corresponding medicine can fall from the medicine storage track 2. The two storage cabinets 1 are fitted with protective covers 4. The protective covers 4 surround the two storage cabinets 1 and can protect the medicine stored inside the storage cabinets 1, so that the medicine can be better stored inside the storage cabinets 1. A medicine receiving frame 5 that can be raised and lowered is installed between the two storage cabinets 1.

[0026] like Figure 3The medicine receiving frame 5 shown has threaded grooves and through holes on both sides at both ends. The two threaded grooves and two through holes are symmetrical about the center point of the medicine receiving frame 5. The medicine receiving frame 5 is connected to the screw 40, which is rotatably connected between the base plate 38 and the base rod 39, through the threaded grooves. It is slidably connected to the limiting rod 41, which is fixedly connected between the base plate 38 and the base rod 39, through the through holes (because the two threaded grooves and two through holes are symmetrical about the center point of the medicine receiving frame 5, it can prevent uneven sinking, so the medicine receiving frame 5 can rise and fall more stably). The upper end of the screw 40 passes through the base plate 38 and is fixedly connected to the motor shaft of the lifting motor 42 mounted on the base plate 38. The lifting and lowering of the medicine receiving frame 5 can be controlled by controlling the rotation of the motor shaft of the lifting motor 42. Each row of medicine storage tracks On one side of the 2 and on the storage cabinet 1, there is a corresponding first touch switch 43. The first touch switch 43 is electrically connected to multiple drug dispensing electric push rods 31 in the same row, and is also electrically connected to the lifting motor 42. During the descent of the drug receiving frame 5, the first touch switches 43 are pressed one by one. When the drug receiving frame 5 presses the first touch switch 43, the descent will stop for a period of time (for example, after 2 seconds, which allows the medicine on the drug storage track 2 to fall into the inside of the drug receiving frame 5) and then continue to descend. When there is medicine to be taken out in the drug storage track 2 in the same row as the pressed first touch switch 43, the output rod of the corresponding drug dispensing electric push rod 37 will retract, so that the medicine falls from the inside of the drug storage track 2 into the inside of the drug receiving frame 5. The upper side of the medicine receiving frame 5 is aligned with the lower end of the current medicine storage track 2, so the medicine falls from a low height and lands on the medicine receiving conveyor belt 6. The medicine receiving conveyor belt 6 is made of rubber and has a certain tension elasticity through the spring structure 19, which can greatly reduce the impact force of the medicine falling and prevent damage to the medicine. When the control module 45 receives the medicine retrieval signal, it can control the lifting motor 42 to drive the screw 40 to rotate clockwise, causing the medicine receiving frame 5 to descend. After the medicine receiving frame 5 descends to the lowest point and presses against the first touch switch 43 located at the bottom, after a certain period of time (for example, after 5 seconds, which allows the medicine falling into the medicine receiving frame 5 to completely fall out of the medicine receiving frame 5), the lifting motor 42 will drive the screw 40 to rotate counterclockwise. The medicine receiving frame 5 is rotated to rise to its highest point, preparing for the next medicine retrieval. The medicine receiving frame 5 is a rectangular frame extending through both the top and bottom. Symmetrically installed inside the medicine receiving frame 5 are two medicine receiving conveyor belts 6, one higher than the other. The lower ends of the two conveyor belts 6 can be controlled to open and close, allowing the medicine to fall. The ends of the two conveyor belts 6 furthest from each other are the outer ends. When the medicine receiving frame 5 reaches its lowest point, the lower ends of the two conveyor belts 6 rotate downwards and separate, allowing the medicine to fall from inside the medicine receiving frame 5. The conveying direction of both conveyor belts 6 is from the outer end to the inner end. The medicine receiving conveyor belts 6 are electrically connected to a second touch switch 44 installed on the lower side of the medicine receiving frame 5. When the medicine receiving frame 5 reaches its lowest point, the base rod 39 presses against the second touch switch 44.At this time, the medication receiving conveyor belt 6 will start, which can effectively prevent the medication from getting stuck on the conveyor belt 6 due to friction and failing to slide off, thus preventing medication retrieval failure. Below the medication receiving frame 5 and between the two storage cabinets 1, a medication dispensing conveyor belt 7 is installed. Medication falling from inside the medication receiving frame 5 will fall onto the dispensing conveyor belt 7. One end of the dispensing conveyor belt 7 extends to the outside of the protective cover 4 through a through-hole. The conveyor belt 7 will transport the medication that falls onto it to the outside of the protective cover 4 for easy retrieval by medical personnel. A medication loading frame 8 is installed on one side of the protective cover 4 for replenishing medication. Medication can be replenished into the storage cabinet 1 through the medication loading frame 8. The number of medication loading frames 8 is the same as the number of rows of medication storage tracks 2 inside the storage cabinet 1, meaning that the medication loading frames 8 can replenish medication into multiple medication storage tracks 2 located in the same row.

[0027] Specifically, both ends of the belt shafts of the two drug-receiving conveyor belts 6, which are close to each other, are rotatably connected to connecting rods 9. The upper ends of the two connecting rods 9 at the same end are hinged to the corresponding sliding frames 10. The two connecting rods 9 at the same end are respectively connected to the belt shafts of the two drug-receiving conveyor belts 6. The opening and closing of the lower ends of the two drug-receiving conveyor belts 6 can be controlled by controlling the raising and lowering of the sliding frames 10. The sliding frames 10 are slidably connected in the sliding groove 11 opened on the inner side of the drug-receiving frame 5 and are fixedly connected to the output rod of the drug-dispensing electric push rod 12 installed inside the sliding groove 11. The drug-dispensing electric push rod 12 is also electrically connected to the second touch switch 44. When the second touch switch 44 is pressed by the base rod 39, the output rod of the drug-dispensing electric push rod 12 will retract, thereby causing the sliding frame 10 to drive the connecting rods 9 to move downward, thereby causing the lower ends of the two drug-receiving conveyor belts 6 to separate (e.g., Figure 6 As shown), the medicine falls smoothly. After a certain period of time (e.g., 3 seconds), the output rod of the medicine dispensing electric push rod 12 will extend again to close the lower ends of the two medicine receiving conveyor belts 6 again, preparing for the next medicine receiving.

[0028] To ensure the conveyor belt 6 remains taut and does not impede transport, a first fixing rod 15 and a second fixing rod 16 are provided. Specifically, both belt shafts of the conveyor belt 6 have annular grooves 13. A collar 14 is rotatably connected inside each groove 13. The outer diameter of the collar 14 is smaller than the outer diameter of the belt shaft of the conveyor belt 6, thus not affecting the transport of the conveyor belt 6. The first fixing rod 15 is fixedly connected to one collar 14, and the second fixing rod 16 is fixedly connected to the other collar 14. An insertion rod 17 is fixedly connected to one end of the second fixing rod 16 near the first fixing rod 15. One end of the insertion rod 17 is inserted into a slot 18 on the first fixing rod 15 and connected to the bottom sidewall of the slot 18 via a spring 19. Both ends are fixedly connected to the bottom sidewall of the slot 18 and the insertion rod 17, respectively. The spring 19 has a tendency to separate the first fixing rod 15 and the second fixing rod 16, so that the two belt shafts of the drug receiving conveyor belt 6 have a tendency to separate from each other. This allows the belt body of the drug receiving conveyor belt 6 to remain taut. The presence of the first fixing rod 15, the spring 19 and the second fixing rod 16 gives the overall shape of the drug receiving conveyor belt 6 stability. In addition, both ends of the connecting rod 9 are hinged. The setting of the spring 19 also allows the two drug receiving conveyor belts 6 to fit together when the drug dispensing electric push rod 12 is extended and the two drug receiving conveyor belts 6 are located inside the drug receiving frame 5, preventing gaps from appearing in the middle and the drug falling out. At this time, the drug receiving conveyor belt 6 does not rotate and does not affect the transmission of the drug.

[0029] To prevent medications from being mixed up and mistakenly taken when medical staff fail to collect them in time, a mounting plate 21 and a guide plate 22 are installed. One end of the medication conveyor belt 7, located outside the protective cover 4, is mounted inside a fixed base 20, which is fixedly connected to the protective cover 4. The mounting plates 21 are symmetrically fixed to the inner wall of the fixed base 20, forming a funnel shape with a larger inner surface and a smaller outer surface. This allows all medications on the medication conveyor belt 7 to move between the two mounting plates 21. The mounting plates 21 are close to the protective cover 4. One end of the cover 4 is the inner end, and the outer end of the mounting plate 21 is hinged to a guide plate 22. The guide plate 22 is driven by a corresponding guide motor 23. The guide motor 23 is mounted on the corresponding mounting plate 21. The rotation of the motor shaft of the guide motor 23 will drive the guide plate 22 to rotate, thereby adjusting the angle of the guide plate 22. The two guide motors 23 start and stop synchronously, so that the two guide plates 22 can rotate the same angle each time and always remain parallel. Before the medicine is transported out by the medicine conveyor belt 7, the guide plate 22 will rotate once to adjust the angle. The adjustment range of the guide plate 22 (e.g., Figure 7(As shown) This system effectively diverts medications, placing them into different external containers to prevent medications from different patients from mixing. The guide motor 23 is electrically connected to the bottommost first touch switch 43 via the control module 45. When the bottommost first touch switch 43 is pressed, the guide motor 23 drives the guide plate 22 to rotate according to the program pre-programmed into the control module 45, thus adjusting the guide plate 22 according to... Figure 7 The order shown is adjusted repeatedly.

[0030] To better guide the medicine on the dispensing conveyor belt 7, the mounting plate 21 and guide plate 22 are equipped with guide shafts 26. Specifically, the inner surfaces of the mounting plate 21 and guide plate 22 are provided with grooves 24. The grooves 24 are rotatably connected to multiple guide shafts 26 through multiple mounting shafts 25 provided between the two side walls of the grooves. The arc surface of the guide shafts 26 is higher than the inner surfaces of the mounting plate 21 and guide plate 22, so that the medicine will only come into contact with the guide shafts 26, and the medicine can be better guided by the mounting plate 21 and guide plate 22.

[0031] Specifically, the medicine loading frame 8 includes a horizontal medicine pushing frame 801 and an inclined medicine dispensing frame 802. The protective cover 4 and the storage cabinet 1 have through openings adapted to the medicine pushing frame 801, which connects to the interior of the storage cabinet 1. The height of the end of the medicine dispensing frame 802 away from the medicine pushing frame 801 is higher than the other end, allowing medicine placed inside the dispensing frame 802 to slide into the medicine pushing frame 801. A stop door 803 is inserted into the end of the dispensing frame 802 away from the medicine pushing frame 801. When medicine needs to be replenished, the stop door 803 can be directly pulled out, allowing the medicine to be replenished to be placed into the dispensing frame. Inside frame 802, the door 803 ensures a sealed interior when not in use, preventing debris from entering. A push plate 27 is slidably connected inside the push frame 801. The position of the push plate 27 within the push frame 801 is controlled by the size of the currently replenished medicine box, ensuring the distance between the push plate 27 and the side wall of the through-hole near the frame 802 matches the size of the medicine box. A push conveyor belt 28 is mounted on the inner side of the push plate 27, with the belt body higher than the inner side of the push plate 27, ensuring the medicine box only comes into contact with the push conveyor belt. The 28 contact each other but not with the push plate 27, thus allowing the pusher conveyor belt 28 to better push the medicine into the storage cabinet 1. A medicine loading conveyor belt 29 is installed inside the storage cabinet 1 and at the outer end of the medicine storage track 2. Medicines pushed into the storage cabinet 1 by the pusher conveyor belt 28 will move onto the medicine loading conveyor belt 29 and continue to be transported into the storage cabinet 1 by the medicine loading conveyor belt 29. A push rod 30 for pushing medicines is installed at the outer end of each medicine storage track 2 and on the outer wall of the storage cabinet 1. The push rod 30 is controlled by a medicine loading electric push rod 31 installed on the storage cabinet 1. Each medicine loading electric push rod 31 has one side located on the storage... Each inner wall of cabinet 1 is equipped with a sensor probe 46, which is electrically connected to the control module 45. The sensor probe 46 can be an MSO-A1640H12T ultrasonic sensor probe. By acquiring distance information and considering the amount of medicine previously removed, the sensor probe 46 is normally in the activated state and can sense the amount of medicine inside the corresponding medicine storage track 2. When the amount of medicine inside the medicine storage track 2 is low, it can send a signal to the control module 45. After receiving the signal, the control module 45 will send a signal to the medical staff's operating terminal (computer) through the network cable so that the medical staff can replenish the medicine in time.

[0032] When medical staff replenish medications, they will input the medications to be replenished into an external computer beforehand. At this time, the control module 45 will stop all sensor probes 46 except the one corresponding to the medication being replenished. Then, when the medication conveyor belt 29 transports the medication to the corresponding medication storage track 2, the corresponding sensor probe 46 will sense the medication. At this time, the sensor probe 46 will control the output rod of the corresponding medication electric push rod 31 to perform a telescopic movement through the control module 45, so that the push rod 30 can push the medication aligned with the medication storage track 2 into the interior of the medication storage track 2. The above steps are repeated continuously to complete the medication replenishment work.

[0033] To facilitate maintenance of the internal components of the medicine pusher frame 801, the end of the medicine pusher frame 801 away from the medicine dispensing frame is designed as a through-hole. In order to prevent the through-hole from communicating with the outside through the opening of the medicine pusher frame 801 and thus reducing the protective effect of the storage cabinet 1 on the medicine, a partition 32 is provided. Specifically, the partition 32 is fixedly connected to the outer surface of the pusher plate 27, and the protective cover 4 has a relief groove 33 adapted to the partition 32. The partition 32 will be inserted into the relief groove 33. When the pusher plate 27 slides, the partition 32 will block the gap between the outer surface of the pusher plate 27 and the through-hole, so that the through-hole and the outer surface of the pusher plate 27 are always sealed, thereby providing a better protection effect for the medicine inside the storage cabinet 1.

[0034] Specifically, a slider 34 is fixedly connected to the outer end face of the push plate 27. The slider 34 extends into a groove 35 on the inner side wall of the medicine loading frame 8 and is fixedly connected to the output rod of the electric push rod 36. The electric push rod 36 is installed inside the groove 35. By controlling the extension and retraction length of the output rod of the electric push rod 36, the position of the push plate 27 inside the medicine loading frame 801 can be controlled. The electric push rod 36 is electrically connected to the control module 45. The control module 45 can control the extension and retraction length of the output rod of the electric push rod 36 according to the size of the outer box of the medicine being loaded.

[0035] The control module 45 and the sensing probe 46 are both existing technologies and are now widely used, so they will not be described in detail in this invention. For example, the control module 45 can be a Raspberry Pi development board.

[0036] The receiving conveyor belt 6, discharging conveyor belt 7, pushing conveyor belt 28, and loading conveyor belt 29 are each driven by a tubular motor 47 installed inside its belt shaft (the installation method of the tubular motor 47 is as follows). Figure 10 (As shown).

[0037] The electric push rod 12 for dispensing medicine, the guide motor 23, the electric push rod 31 for adding medicine, the electric push rod 36 for pushing medicine, the electric push rod 37 for dispensing medicine, the lifting motor 42, the control module 45, the induction probe 46, and the tubular motor 47 are all connected to an external power source via cables.

[0038] Working principle: When retrieving medication, medical staff input the medication to be retrieved through the operating terminal (computer). At this time, the medication receiving frame 5 will gradually move downward. When the medication receiving frame 5 presses against the first touch switch 43 located in the same row, the corresponding lifting plate 3 will descend, causing the medication to fall into the inside of the medication receiving frame 5. When the medication receiving frame 5 moves to the bottom, the lower ends of the two medication receiving conveyor belts 6 will open and start, causing the medication to fall onto the medication dispensing conveyor belt 7. The medication dispensing conveyor belt 7 will move the medication to the outside of the protective cover 4 for easy retrieval by medical staff.

[0039] When administering medication, medical staff enter the medication to be supplemented into the computer, and then place the medication into the medication container 802. The medication conveyor belt 28, the medication delivery conveyor belt 29, and the push rod 30 work together to complete the medication delivery.

[0040] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
