Description

A conveying device and method for storing and dispensing medicines. Technical Field

[0001] This invention relates to the field of pharmaceutical storage and dispensing technology, and in particular to a conveying device and method for pharmaceutical storage and dispensing. Background Technology

[0002] In existing hospital pharmacies, when dispensing medications, the dispensing equipment pushes the drugs to the dispensing slot, and medical staff then retrieve the medications from the dispensing slot and deliver them to the medical staff at the dispensing station. This process is cumbersome and increases labor costs. Summary of the Invention

[0003] Based on the above analysis, the present invention aims to provide a conveying device and method for drug storage and distribution, in order to solve the problems of cumbersome procedures and high labor costs in the existing drug distribution process.

[0004] The objective of this invention is mainly achieved through the following technical solutions:

[0005] On one hand, the present invention provides a conveying device for drug storage and dispensing, including a support frame, a horizontal conveying mechanism, a vertical conveying mechanism, and a dispensing station table. The horizontal conveying mechanism is located on the top of the support frame, the upper end of the vertical conveying mechanism is connected to one end of the horizontal conveying mechanism, and the lower end of the vertical conveying mechanism is located on the top of the dispensing station table. After the drug is conveyed from the horizontal conveying mechanism to the vertical conveying mechanism, it is conveyed to the dispensing station table through the vertical conveying mechanism.

[0006] Furthermore, the horizontal conveying mechanism includes a horizontal support frame, a first roller, a second roller, and a first belt. The first roller and the second roller are respectively located at both ends of the horizontal support frame, and the first belt connects the first roller and the second roller.

[0007] Furthermore, the vertical conveying mechanism includes a vertical drop cylinder, the upper end of which is located on one side of the first belt, and the lower end of which is located on the top of the distribution station table.

[0008] Furthermore, the lower end side wall of the vertical drop cylinder is provided with a medicine outlet.

[0009] Furthermore, the horizontal conveying mechanism also includes a first guard plate, a second guard plate, and a bottom guard plate. The first guard plate and the second guard plate are respectively disposed on both sides of the horizontal support frame, and the bottom guard plate is disposed below the horizontal support frame.

[0010] Furthermore, the horizontal conveying mechanism also includes a support roller shaft, the two ends of which are respectively connected to the first guard plate and the second guard plate, and the support roller shaft is disposed between the first belt and the bottom guard plate.

[0011] Furthermore, the support frame includes a first support frame and a second support frame with identical structures, and the two ends of the horizontal conveying mechanism are respectively located on the top of the first support frame and the second support frame.

[0012] Furthermore, the support frame also includes a first side plate, a second side plate, and a third side plate, wherein the first side plate and the third side plate are arranged in parallel, and the two ends of the second side plate are respectively perpendicularly connected to the first side plate and the third side plate.

[0013] Furthermore, the first support frame includes a first column, a first crossbeam, a first L-shaped connecting plate, and a first connecting plate. Each end of the first crossbeam is connected to a first column. The first connecting plate is perpendicular to the first crossbeam. Both the first L-shaped connecting plate and the first connecting plate are connected to the top of the first column.

[0014] On the other hand, the present invention provides a method for storing and distributing medicines, which uses the above-mentioned conveying device for storing and distributing medicines to convey and distribute medicines.

[0015] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0016] (1) The present invention has a horizontal conveying mechanism at the top of the support frame. The medicine is conveyed from one end of the horizontal conveying mechanism above the workstation to the top of the vertical conveying mechanism, and then from the horizontal conveying mechanism to the vertical conveying mechanism. It is then directly conveyed to the distribution workstation table through the vertical conveying mechanism, and distributed to the recipient by medical staff. This reduces intermediate links and also reduces labor costs.

[0017] (2) The horizontal conveying mechanism of the present invention includes a second motor and a limiting swing rod. The second motor is connected to the horizontal support frame, and the limiting swing rod is connected to the output shaft of the second motor. Under the drive of the second motor, the limiting swing rod swings between a first position and a second position. When the limiting swing rod is on the first belt, it blocks the medicine on the first belt, so that the medicine stops on one side of the limiting swing rod, so as to push the medicine from the first belt to the vertical conveying mechanism, thereby realizing the conveying of the medicine.

[0018] (3) The vertical conveying mechanism of the present invention includes a medicine buffer assembly, which is disposed in a vertical drop cylinder and connected to a linear guide rail. The medicine buffer assembly includes a third connecting plate, a support base, a connecting shaft, a receiving plate, a limiting plate, a first limiting frame, and a second limiting frame. The medicine falls from the top of the vertical drop cylinder and first falls onto the receiving plate, which is in a horizontal state, for buffering. Then the receiving plate moves downward. When it contacts the first limiting frame, the receiving plate tilts, and the medicine slides off the receiving plate and out of the medicine outlet at the bottom of the vertical drop cylinder. The receiving plate then moves upward. During this process, the receiving plate will return to a horizontal state. This process is repeated to buffer and convey the medicine, thereby avoiding or reducing the risk of damage to the packaging box or even the medicine itself caused by the medicine falling from a height.

[0019] In this invention, the above-described technical solutions can be combined with each other to achieve more preferred combinations. Other features and advantages of this invention will be set forth in the following description, and some advantages may become apparent from the specification or be learned by practicing the invention. The objectives and other advantages of this invention can be realized and obtained from the content specifically pointed out in the text and accompanying drawings. Attached Figure Description

[0049] 4. Distribute workstations. Detailed Implementation

[0050] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0051] Example 1

[0052] A specific embodiment of the present invention, as shown in Figures 1-23, discloses a conveying device (hereinafter referred to as "conveying device") for drug storage and dispensing. As shown in Figures 1 and 2, the conveying device includes a support frame 1, a horizontal conveying mechanism 2, a vertical conveying mechanism 3, and a dispensing station table 4. The horizontal conveying mechanism 2 is located on the top of the support frame 1, the upper end of the vertical conveying mechanism 3 is connected to one end of the horizontal conveying mechanism 2, and the lower end of the vertical conveying mechanism 3 is located on the top of the dispensing station table 4.

[0053] The conveying device provided in this embodiment has a horizontal conveying mechanism 2 at the top of the support frame 1. The medicine is conveyed from one end of the horizontal conveying mechanism 2 above the workstation to the top of the vertical conveying mechanism 3, and then from the horizontal conveying mechanism 2 to the vertical conveying mechanism 3. It is then directly conveyed to the distribution workstation table 4 through the vertical conveying mechanism 3, where it is distributed to the recipient by medical staff. This reduces intermediate links and also lowers labor costs.

[0054] As shown in Figure 5, the support frame 1 includes a first support frame 11 and a second support frame 12. The two ends of the horizontal conveying mechanism 2 are respectively located at the top of the first support frame 11 and the second support frame 12. The bottom of the first support frame 11 and the second support frame 12 can be fixed to the ground by anchor bolts, or they can be left unfixed. As shown in Figures 5, 6 and 7, the first support frame 11 includes a first pillar 111, a first crossbeam 112, a first L-shaped connecting plate 113 and a first connecting plate 114. There are four first pillars 111, which are located at the four corners of the rectangle. There are also multiple first crossbeams 112, which are parallel to each other, and each end of the first crossbeam 112 is connected to a first pillar 111. There are two first L-shaped connecting plates 113 and two first connecting plates 114, which are symmetrically arranged. The first connecting plate 114 is perpendicular to the first crossbeam 112. Both the first L-shaped connecting plate 113 and the first connecting plate 114 are connected to the top of the first support column 111. The first support frame 11 also includes a first connecting base plate 115. There are two first connecting base plates 115, which are parallel to each other and parallel to the first crossbeam 112. The two ends of the first connecting base plate 115 are respectively connected to the bottom of one of the first support columns 111.

[0055] The second support frame 12 has the same structure as the first support frame 11. Specifically, as shown in Figure 5, the second support frame 12 includes second pillars 121, second crossbeams 122, second L-shaped connecting plates 123, and second connecting plates 124. There are four second pillars 121, located at the four corners of a rectangle. There are also multiple second crossbeams 122, which are parallel to each other, with each end of a second crossbeam 122 connected to a second pillar 121. There are two second L-shaped connecting plates 123 and two second connecting plates 124, symmetrically arranged. The second connecting plates 124 are perpendicular to the second crossbeams 122. Both the second L-shaped connecting plates 123 and 124 are connected to the top of the second pillars 121. The second support frame 12 also includes a second connecting base plate 125. There are two second connecting base plates 125, which are parallel to each other and parallel to the second crossbeam 122. The two ends of the second connecting base plate 125 are respectively connected to the bottom of a second column 121.

[0056] As shown in Figures 1, 2, and 3, the support frame 1 also includes a first side plate 13, a second side plate 14, and a third side plate 15. The first side plate 13 and the third side plate 15 are arranged in parallel. The two ends of the second side plate 14 are perpendicularly connected to the first side plate 13 and the third side plate 15, respectively, to form a U-shaped structure. A first through hole 131 is provided on one side of the top of the first side plate 13, and a second through hole 151 is provided on one side of the top of the third side plate 15. Two first pillars 111 are located on one side of the first side plate 13, and two other first pillars 111 are located on the other side of the first side plate 13. Two first L-shaped connecting plates 113 are respectively provided on both sides of the first side plate 13. Two first connecting plates 114 span the first through hole 131. Two second pillars 121 are located on one side of the third side plate 15, and two other second pillars 121 are located on the other side of the third side plate 15. Two second L-shaped connecting plates 123 are respectively provided on both sides of the third side plate 15, and two second connecting plates 124 span the second through hole 151. A doorway 141 is provided on the second side panel 14.

[0057] As shown in Figures 13, 14 and 15, the horizontal conveying mechanism 2 includes a horizontal support frame 21, a first roller 22, a second roller 23 and a first belt 24. The first roller 22 and the second roller 23 are respectively located at both ends of the horizontal support frame 21, and the first belt 24 connects the first roller 22 and the second roller 23.

[0058] As shown in Figures 11, 12, 13, 14, and 15, the horizontal conveying mechanism 2 also includes a first guard plate 25, a second guard plate 26, and a bottom guard plate 27 of equal length. The first guard plate 25 and the second guard plate 26 are respectively located on both sides of the horizontal support frame 21 and are arranged in parallel. The bottom guard plate 27 is located below the horizontal support frame 21 and is parallel to the horizontal support frame 21. The bottom guard plate 27 is connected to the bottom of the first guard plate 25 and the second guard plate 26, as shown in Figures 8 and 9. The two ends of the bottom guard plate 27 are respectively connected to the first L-shaped connecting plate 113 and the second L-shaped connecting plate 123. The two sides of the horizontal support frame 21 are connected to the middle of the first guard plate 25 and the second guard plate 26, so that there is a gap between the bottom of the first belt 24 and the bottom guard plate 27. During the movement of the medicine on the first belt 24, the first guard plate 25 and the second guard plate 26 can prevent the medicine from falling off the first belt 24. It should be noted that the first L-shaped connecting plate 113 and the second L-shaped connecting plate 123 connected to the two ends of the bottom guard plate 27 are located between the first side plate 13 and the third side plate 15.

[0059] Considering the long transport distance of the medicine, to prevent the lower part of the first belt 24 from sagging, as shown in Figures 13, 14, and 15, the horizontal conveying mechanism 2 further includes a support roller shaft 28. The two ends of the support roller shaft 28 are connected to the first guard plate 25 and the second guard plate 26, respectively. The support roller shaft 28 is located between the first belt 24 and the bottom guard plate 27. Preferably, multiple support roller shafts 28 are provided, and the multiple support roller shafts 28 are evenly distributed along the length direction of the first belt 24.

[0060] To achieve the rotation of the first belt 24, as shown in Figures 9 and 10, the horizontal conveying mechanism 2 also includes a first motor 29, a first pulley 20, a second pulley (not shown in the figures), and a second belt (not shown in the figures). The first motor 29 is located near the second roller shaft 23 and is connected to the first guard plate 25. The first pulley 20 is connected to the second roller shaft 23, and the second pulley is connected to the output shaft of the first motor 29. The second pulley connects the first pulley 20 and the second pulley. The first motor 29 drives the second pulley to rotate, which in turn drives the first pulley 20 to rotate via the second belt, thereby driving the second roller shaft 23 to rotate and thus realizing the operation of the first belt 24. The medicine is conveyed from one end of the first belt 24 (the end of the first roller shaft 22) to the other end (the end of the second roller shaft 23).

[0061] Since the vertical conveying mechanism 3 is located on one side of the end of the horizontal conveying mechanism 2, that is, on one side of the second guard plate 26, the medicine is conveyed from the first belt 24 to the vertical conveying mechanism 3. Therefore, as shown in Figure 9, the end of the second guard plate 26 is provided with an opening 261. The opening 261 is lower than the top surface of the first belt 24 to avoid hindering the medicine from being pushed from the first belt 24 to the vertical conveying mechanism 3.

[0062] The medicine is conveyed to one end of the first belt 24 by the dispensing device. After being conveyed from one end of the first belt 24 to the other end (i.e., the end of the second roller 23), it needs to be conveyed to the vertical conveyor mechanism 3. Therefore, the medicine needs to stay on the first belt 24 relative to the second roller 23. The horizontal conveyor mechanism 2 also includes a second motor 201 and a limiting swing rod 202. The second motor 201 is connected to the horizontal support frame 21, and the limiting swing rod 202 is connected to the output shaft of the second motor 201. Driven by the second motor 201, the limiting swing rod 202 swings between a first position and a second position. In the first position, the limiting swing rod 202 is located on the first belt 24, blocking the medicine on the first belt 24 and stopping it on one side of the limiting swing rod 202. In the second position, the limiting swing rod 202 swings to the vertical conveyor mechanism 3, at which time the medicine is pushed from the first belt 24 to the vertical conveyor mechanism 3. After the medicine is pushed out, the limiting swing rod 202 swings back to its original position. It should be noted that when the limit lever 202 swings away from the first belt 24, the first belt 24 stops running or runs at a low speed to prevent the medicine from continuing to move forward along the length of the first belt 24 and being transported out of the position corresponding to the vertical conveyor 3, thus making it impossible to transport the medicine from the first belt 24 to the vertical conveyor 3.

[0063] Understandably, the horizontal conveying mechanism 2 also includes a drug-pushing assembly (not shown in the figure). The drug-pushing assembly includes a cylinder and a pusher plate. The cylinder is located near the first motor 29 and connected to the first guard plate 25. The pusher plate is connected to the push rod of the cylinder. Under the action of the cylinder, the pusher plate pushes the drug off the first belt 24. Correspondingly, a hole (not shown in the figure) is provided on the first guard plate 25 for the pusher plate to pass through. The bottom of the pusher plate is flush with or slightly higher than the top of the first belt 24, such as 1-2 mm.

[0064] Referring to Figures 1, 2, 3, 16, and 19, the vertical conveying mechanism 3 includes a vertical drop cylinder 31, a third motor 32, and a linear guide rail 33. The upper end of the vertical drop cylinder 31 is located on one side of the first belt 24, and the lower end of the vertical drop cylinder 31 is located on the top of the dispensing station table 4. One side of the vertical drop cylinder 31 is connected to the second support column 121 located inside the third side plate 15. The linear guide rail 33 is located inside the vertical drop cylinder 31, and the third motor 32 is located at one end of the linear guide rail 33, preferably at the lower end of the linear guide rail 33. The lower end of the linear guide rail 33 is fixed to the ground, and the third motor 32 is used to drive the linear guide rail 33. It should be noted that the linear guide rail 33 has a structure including a belt, a pulley, and its support frame. The third motor 32 drives the pulley, thereby driving the belt to run.

[0065] It is worth noting that, in order to facilitate the installation and maintenance of components inside the vertical drop cylinder 31, one side panel of the vertical drop cylinder 31 can be opened. That is, one side panel of the vertical drop cylinder 31 is connected to other side panels through cabinet door hinges. When it is necessary to observe the internal condition of the vertical drop cylinder 31, install other components, or carry out maintenance, one side panel can be opened.

[0066] Considering the relatively high length of the vertical drop cylinder 31 (generally the distance from the ceiling to the tabletop), in order to avoid or reduce the risk of damage to the packaging box or even the medicine due to the medicine falling from a height, as shown in Figures 16 and 18, the vertical conveying mechanism 3 also includes a medicine buffer assembly 34. The medicine buffer assembly 34 is located in the vertical drop cylinder 31 and is connected to the linear guide rail 33. Under the drive of the linear guide rail 33, it can move up and down along the length direction of the linear guide rail 33.

[0067] Specifically, as shown in Figures 20, 21, 22, and 23, the drug buffer assembly 34 includes a third connecting plate 341, a support base 342, a connecting shaft 343, and a drug receiving plate 344. One end of the third connecting plate 341 is connected to the first connecting block 331 on the linear guide rail 33, and the other end of the third connecting plate 341 is connected to the lower end of the support base 342. The connecting shaft 343 is connected to the upper end of the support base 342. The bottom upper end of the drug receiving plate 344 is rotatably connected to the connecting shaft 343 via a second connecting block 345. To prevent the drug from slipping off both sides of the drug receiving plate 344, flanges 3441 are provided on both sides of the drug receiving plate 344.

[0068] To ensure the receiving plate 344 is tilted, as shown in Figures 20, 21, 22, and 23, the drug buffer assembly 34 further includes a limiting plate 346, a first limiting frame 347, and a second limiting frame 348. The limiting plate 346 is located at the bottom of the receiving plate 344, with its upper end connected to the bottom of the receiving plate 344. The bottom of the limiting plate 346 can contact the side wall of the support base 342. The first limiting frame 347 is connected to the side wall of the linear guide rail 33, and the second limiting frame 348 is connected to the support base 342. The second limiting frame 348 and the limiting plate 346 are respectively located on both sides of the support base 342, and the first limiting frame 347 and the second limiting frame 348 are located on the same side of the support base 342.

[0069] Further, referring to Figures 20, 21, 22, and 23, the first limiting frame 347 includes a third L-shaped connecting plate 3471 and a first support column 3472. The vertical plate of the third L-shaped connecting plate 3471 is connected to the linear guide rail 33, and the horizontal plate of the third L-shaped connecting plate 3471 is connected to the first support column 3472. Preferably, there are two first support columns 3472, and the top of the first support column 3472 is an inclined surface, which contacts the thickened block 3442 at the upper bottom of the support base 342. It should be noted that the vertical plate of the third L-shaped connecting plate 3471 has an elongated hole, which allows for adjustment of the installation height with the third L-shaped connecting plate 3471.

[0070] As shown in Figures 20, 21, 22 and 23, the second limiting frame 348 includes a fourth L-shaped connecting plate 3481 and a second support column 3482. The vertical plate of the fourth L-shaped connecting plate 3481 is connected to the support base 342. The support base 342 is provided with an elongated hole 3421, through which the installation position of the second limiting frame 348 can be adjusted. The second support column 3482 is provided on the horizontal plate of the fourth L-shaped connecting plate 3481, and the top of the second support column 3482 is used to support the thickening block 3442.

[0071] When the receiving plate 344 receives the medicine, it is in a horizontal position. After receiving the medicine, the third motor 32 runs, driving the medicine buffer assembly 34 downward. When the thickening block 3442 contacts the first support column 3472, the third motor 32 stops running, and the receiving plate 344 tilts (the limiting plate 346 limits the tilt angle of the receiving plate 344), causing the medicine to slide off the receiving plate 344 and out of the medicine outlet 311 on the bottom side wall of the vertical drop cylinder 31. When the medicine buffer assembly 34 runs upward under the drive of the third motor 32, the receiving plate 344 returns to a horizontal position under the action of the torsion spring (not shown in the figure). At this time, the second support column 3482 contacts the bottom of the thickening block 3442, preventing the receiving plate 344 from over-rotating. It should be noted that the torsion spring is sleeved on the connecting shaft 343, and the claws of the torsion spring are connected to the bottom of the support seat 342 and the receiving plate 344, respectively.

[0072] To prevent the medicine from slipping off the end of the receiving plate 344 where the thickening block 3442 is provided, as shown in Figures 20, 21, 22 and 23, the receiving plate 344 is provided with a medicine baffle plate 3443.

[0073] To limit the height of the drug buffer assembly 34, as shown in Figures 16 and 17, the vertical conveying mechanism 3 also includes a limit switch 35, which is located in the middle of the linear guide rail 33. The drug buffer assembly 34 also includes a trigger plate 349, which is connected to the first connecting block 331. When the trigger plate 349 contacts the limit switch 35, the third motor 32 stops running and then reverses to drive the drug buffer assembly 34 downward. After the medicine receiving plate 344 tilts and the medicine slides down, the third motor 32 reverses and drives the drug buffer assembly 34 upward again.

[0074] Understandably, as shown in Figure 13, the support frame 1 also includes a protective plate 16. One end of the protective plate 16 is located at the top of the vertical drop cylinder 31 and inside the second through hole 151, while the other end is located inside the first through hole 131. As shown in Figure 4, the vertical conveying mechanism 3 also includes an inclined plate 36. One side of the inclined plate 36 is connected to the horizontal support frame 21, and the other side is suspended above the top of the vertical drop cylinder 31. The horizontal projection of the inclined plate 36 covers the area of ​​the medicine-blocking plate 3443 and one end of the medicine-receiving plate 344 (the end with the thickening block 3442) in the horizontal state of the medicine-receiving plate 344.

[0075] Example 2

[0076] Another specific embodiment of the present invention, as shown in FIG24, discloses a conveying device for drug storage and dispensing. The difference from Embodiment 1 is that the vertical conveying mechanism 3 only includes a vertical drop cylinder 31, without any other power mechanism. Drugs falling into the vertical drop cylinder 31 from the first belt 24 fall downwards by their own weight. To mitigate the impact of the drugs, a buffer plate 312 is provided inside the vertical drop cylinder 31. The buffer plate 312 is inclined downwards. Preferably, multiple buffer plates 312 are provided, and the multiple buffer plates 312 are staggered on two parallel sidewalls of the vertical drop cylinder 31.

[0077] Understandably, one side panel of the vertical drop cylinder 31 can be opened, that is, one side panel of the vertical drop cylinder 31 is connected to other side panels through cabinet door hinges, so as to allow for maintenance inside the vertical drop cylinder 31.

[0078] Example 3

[0079] Another specific embodiment of the present invention discloses a method for storing and dispensing medicines, employing the medicine storage and dispensing conveying device of Embodiment 1, comprising the following steps:

[0080] Step 1: The medicine is transported from one end of the first belt 24 to the other end.

[0081] Specifically, the medicine is transported to one end of the first belt 24 (i.e., the end of the first roller 22) by the dispensing equipment, and the second roller 23 is driven to rotate by the first motor 29, thereby realizing the operation of the first belt 24, which transports the medicine from one end to the other end, and the limiting swing rod 202 restricts the medicine from moving forward, so that the medicine stops facing the vertical drop cylinder 31.

[0082] Step 2: The medicine is pushed into the vertical drop tube 31.

[0083] Specifically, when the second motor 201 operates, the limiting swing rod 202 swings from the first position to the second position, no longer restricting the medicine on the first belt 24. The cylinder starts, driving the push plate forward to push the medicine into the vertical drop cylinder 31. Then the push plate resets, the second motor 201 reverses, and the limiting swing rod 202 resets, returning to the first position. It should be noted that when the limiting swing rod 202 leaves the first position, the first motor 29 runs at low speed to prevent the medicine from moving too far forward and failing to be pushed into the vertical drop cylinder 31. Alternatively, the first motor 29 can be stopped and restarted after the medicine has been pushed down.

[0084] Step 3: The medicine falls onto the horizontal medicine receiving plate 344 and descends until the medicine receiving plate 344 tilts and the medicine slides out from the medicine outlet 311.

[0085] Specifically, the third motor 32 operates, driving the first connecting block 331 to move downwards. The thickened block 3442 at the bottom of the receiving plate 344 contacts the inclined surface of the first support column 3472, causing the receiving plate 344 to tilt. At this time, the third motor 32 stops operating, and the limiting plate 346 contacts the support seat 342 to limit the tilt angle of the receiving plate 344. The medicine slides off the receiving plate 344 and slides out from the medicine outlet 311 at the bottom of the vertical drop cylinder 31, and is distributed to the recipient by medical personnel.

[0086] Step 4: Reset the medicine receiving plate 344.

[0087] Specifically, the third motor 32 reverses, and the receiving plate 344 moves upward. At this time, under the action of the torsion spring, the receiving plate 344 returns to a horizontal state. The second support column 3482 contacts the thickening block 3442, so that the receiving plate 344 is in a horizontal state. The trigger plate 349 contacts the limit switch 35, and the third motor 32 stops running, ready to pick up the next round of falling medicines. This process is repeated to achieve continuous delivery and distribution of medicines.

[0088] In this embodiment, the medicine is conveyed from the dispensing device onto the first belt 24, transported from one end of the first belt 24 to the other end, and then pushed onto the vertical drop cylinder 31. It falls from the top of the vertical drop cylinder 31 and first lands on the horizontal receiving plate 344 for cushioning. Then the receiving plate 344 moves downward. When it contacts the first limiting frame 347, the receiving plate 344 tilts, and the medicine slides off the receiving plate 344 and out of the medicine outlet 311 at the bottom of the vertical drop cylinder 31. The receiving plate 344 then moves upward. During this process, the receiving plate 344 returns to a horizontal state. This process is repeated to convey the medicine directly to the dispensing station table 4, where medical personnel distribute it to the recipient, reducing intermediate steps and lowering labor costs.

[0089] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
