Description

Technical Field

[0001] This utility model belongs to the field of dispensing equipment technology, and in particular relates to a dispensing system. Background Technology

[0002] Traditional Chinese medicine (TCM) pharmacies suffer from efficiency bottlenecks. Specifically, during prescription dispensing, pharmacists must perform multiple steps within a large, complexly zoned medicinal herb storage space, based on handwritten prescriptions. Current TCM pharmacies typically exhibit the following characteristics: first, they stock over a thousand different medicinal herbs, with most prescriptions involving 10-20 different herbs; second, their storage systems employ multi-layered, three-dimensional shelving, with various herbs stored in differentiated locations according to their properties. This spatial layout forces pharmacists to continuously move between different storage units, manually locating, selecting, and weighing herbs one by one, significantly increasing the average dispensing time per prescription and necessitating improvements in overall operational efficiency. Summary of the Invention

[0003] To address the aforementioned technical problems, this utility model discloses a dispensing system that can effectively improve the efficiency of pharmacy dispensing, reduce pharmacy staffing, and increase economic benefits.

[0004] The specific technical solution of this utility model is as follows:

[0005] A dispensing system, comprising:

[0006] A conveying mechanism that collects medicines along a conveying direction;

[0007] A medicine rack is set on one or both sides of the conveying mechanism. The medicine rack is equipped with multiple medicine storage containers arranged in an array. The medicine storage containers contain small packaged medicine pieces in bags. Any two medicine storage containers contain different types of medicines or different specifications of the same type of medicines. The medicine storage containers are equipped with a dispensing device. The dispensing device cuts the bags into a planned number of bags according to the prescription information and throws the cut planned number of bags towards the conveying mechanism.

[0008] A packaging mechanism, located at the end of the conveying mechanism, is used to bag and pack the medicines collected by the conveying mechanism.

[0009] The conveying mechanism can transport the prescription drugs to the packaging mechanism so that the packaging mechanism can output the drugs needed by the patient. After obtaining the information of the prescription drugs, the dispensing device in the corresponding drug storage container is activated, so that the corresponding small package of medicinal slices is cut and thrown onto the conveying mechanism, thereby effectively improving the efficiency of dispensing drugs, reducing the input of pharmacy personnel, and improving economic benefits.

[0010] Preferably, the conveying mechanism includes a conveyor belt with multiple drug storage spaces arranged along its circumference, and the drugs to be dispensed for the same prescription are thrown into the same drug storage space by multiple dispensing devices.

[0011] Each medication storage space stores medications according to different prescriptions, thereby enabling automated dispensing and improving dispensing efficiency.

[0012] Preferably, the dispensing device includes a bag feeding mechanism, a bag cutting mechanism, and a bag throwing mechanism;

[0013] The bag feeding mechanism includes a feeding belt 1 and a feeding belt 2 arranged opposite to each other. The feeding belt 1 and the feeding belt 2 drive several consecutive packaging bags containing materials to move between the feeding belt 1 and the feeding belt 2 to be transferred to the bag cutting mechanism. The bag cutting mechanism opens and closes to cut the consecutive packaging bags into a planned number of packaging bags.

[0014] The bag throwing mechanism includes a first roller and a second roller arranged opposite to each other, which throws a planned number of packaging bags from between the first roller and the second roller using an adjustment device;

[0015] The linear velocity of the packaging bag moving between feed belt one and feed belt two is less than its linear velocity moving between roller one and roller two.

[0016] In this application, the bag feeding mechanism, the bag cutting mechanism, and the bag throwing mechanism cooperate with each other to achieve accurate and efficient dispensing according to the prescription. Since the linear velocity of the packaging bag moving between the first and second feeding belts is less than its linear velocity moving between the first and second rollers, the speed of the packaging bag at the bag throwing mechanism is greater than its speed at the bag feeding mechanism, thereby throwing the medicine bag out. At the same time, it avoids the packaging bag in front of the bag cutting mechanism from blocking the movement of the packaging bag behind it and affecting the dispensing effect.

[0017] Preferably, the first roller has a plurality of spaced protrusions arranged along its circumference, and the protrusions extend along the axis of the first roller.

[0018] The protruding ridges can create an impact on the packaging bag, thereby better meeting the requirements for bag disposal.

[0019] Preferably, the bag-cutting mechanism includes:

[0020] A fixed clamping member one, and a clamping member two that can move toward or away from the clamping member one; and

[0021] The driving component is used to drive the movement of the clamping component two.

[0022] The clamping components one and two can abut against each other, clamping the packaging bag tightly before cutting it, thereby achieving the cutting of the planned quantity of packaging bags.

[0023] Preferably, the clamping member two includes:

[0024] Linkage seat, wherein the linkage seat is connected to the drive component in a transmission manner;

[0025] The pressure block and the guide rod 1, one end of the guide rod 1 is fixedly connected to the pressure block, and the other end is slidably engaged with the connecting rod seat. An elastic element 1 is sleeved on the outer side of the guide rod 1.

[0026] A cutter, which is connected to a connecting rod seat and located on one side of the pressure block;

[0027] The clamping member has a groove for engaging the cutter;

[0028] The bag-cutting mechanism also includes:

[0029] Guide rod two, the connecting rod seat and guide rod two are in sliding fit, and guide rod two is parallel to the movement path of the connecting rod seat.

[0030] The structure is simple and easy to implement. Under the action of the driving component, the connecting rod seat drives the pressure block to press the packaging bag against the clamping component one. Then the driving component continues to move, causing the elastic element one to compress and deform. When the pressure block is relatively stationary, the cutter continues to move and cuts the continuous packaging bags in the cutting groove. Finally, it can be reset. Since the connecting rod seat and the guide rod two slide together, the stable movement of the connecting rod seat can be achieved, thereby achieving stable cutting by the cutter.

[0031] Preferably, the bag cutting mechanism is equipped with a through-beam sensor and a color mark sensor, there is a transparent area between any two adjacent bags, and each bag is provided with a mark strip;

[0032] When the through-beam sensor detects the transparent area and the color mark sensor detects the mark strip, the bag cutting mechanism cuts the packaging bag.

[0033] This setup enables the bag-cutting mechanism to accurately cut the packaging bags. The through-beam sensor and / or color mark sensor can also be used for counting, and the decision to cut the bag is made based on the count, thus better meeting the prescription dispensing requirements.

[0034] Preferably, the feed end and / or discharge end of the first feeding belt is provided with a driven cylinder, a shaft is inserted into the driven cylinder, the driven cylinder rotates around the axis of the shaft, and the driven cylinder can move closer to or away from the second feeding belt; the end of the shaft is cut with a sunken plane along the axis, and a floating component is connected to the sunken plane;

[0035] And / or, the bag throwing mechanism has a housing one, and the roller two is slidably engaged with the housing one, so that the roller two can dynamically float equivalent to the roller one.

[0036] Because the packaging bag contains materials, the materials will cause the packaging bag to form a regular or irregular arch shape. Therefore, the adjustable roller one and / or roller two can adapt to the above-mentioned arch shape, thereby achieving better bag throwing by adjusting the relative distance between roller one and roller two. Since the packaging bag has regular or irregular protrusions on its surface after being filled with materials and sealed, in order to adapt to packaging bags of different thicknesses during the transfer of packaging bags, floating components are used to achieve adaptive up and down movement, thereby ensuring that feeding belt one and feeding belt two are always in close contact with and press the packaging bag, ensuring transfer efficiency.

[0037] Preferably, the bag feeding mechanism is provided with a housing two;

[0038] The floating component includes:

[0039] A floating rod, one end of which is fixedly connected to the sinking plane, and the other end is slidably engaged with the housing. An elastic element is sleeved on the outer side of the floating rod.

[0040] The structure is simple and easy to implement, and can well meet the requirements of the feeding belt for self-adaptive bonding and compression of packaging bags.

[0041] Preferably, it also includes a motor, which is divided into a power source and a power source. The power source is used to drive the feeding belt or the feeding belt, which is connected in a transmission. The power source is used to drive the roller.

[0042] The first roller is equipped with a one-way bearing.

[0043] This application utilizes a single motor to achieve all power output, which can meet the requirements of motion synchronization, and saves costs and assembly space. Since the roller is equipped with a one-way bearing, the motor can only drive the bag throwing mechanism to rotate in one direction. When the motor reverses, the bag throwing mechanism is in a stationary and inactive state, which makes it convenient to use the motor to drive the feeding mechanism to reverse to solve the problem of bag jamming.

[0044] Compared with existing technologies, this invention dispenses the required medicines from different storage containers based on prescription information, thereby meeting the prescription dispensing requirements. The storage containers of this invention are compactly arranged and rationally coordinated with the dispensing device, effectively adapting to the transfer requirements of the conveying mechanism. In addition, this invention can flatten continuously conveyed packaging bags and utilizes floating components to ensure the transfer efficiency of packaging bags. This invention effectively meets the cutting requirements of packaging bags through the bag cutting component, enabling the cutting of single bags or multiple bags, thereby expanding the application range. This invention significantly reduces the workload of dispensing personnel and effectively improves the efficiency of dispensing medicines through automated packaging bag transfer, cutting, and dispensing.

Detailed Implementation

[0054] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to specific embodiments.

[0055] like Figures 1-2As shown, a dispensing system includes a conveying mechanism 500 and a packaging mechanism 600, as well as a medicine rack 700 disposed on one or both sides of the conveying mechanism 500. The conveying mechanism 500 collects medicines along the conveying direction. The medicine rack 700 is provided with a plurality of medicine storage containers 41 arranged in an array. Each medicine storage container 41 contains a small packaged herbal medicine bag 400 connected to a pouch. Any two medicine storage containers 41 contain different types of medicines or medicines of the same type but with different specifications. Each medicine storage container 41 is provided with a dispensing device. The dispensing device cuts the connected pouches 400 into a planned number of pouches 400 according to the prescription information and throws the cut pouches 400 towards the conveying mechanism 500. The packaging mechanism 600 is disposed at the end of the conveying mechanism 500 and is used to bag and package the medicines collected by the conveying mechanism 500.

[0056] In this embodiment, medicine racks 700 are provided on both sides of the conveying mechanism 500. Each medicine rack 700 has M*N grids, where M and N are positive integers. Each grid is configured as a medicine storage container 41. These medicine storage containers 41 have a certain volume to store small packaged herbal medicine bags 400 of appropriate length to meet the requirements of long-term use, and have an installation volume suitable for placing the dispensing device. During the operation of the conveying mechanism 500, the packaged bags 400 in each medicine storage container 41 are cut and thrown onto the conveying mechanism 500. After the conveying mechanism 500 collects all the medicines listed in the prescription, they are put into the packaging mechanism 600 for packaging. After packaging, the medicine can be dispensed to the patient. The packaging mechanism can be a commonly used packaging device, which is commercially available and will not be described in detail here.

[0057] In this embodiment, the conveying mechanism 500 includes a conveyor belt with multiple drug storage spaces 42 arranged along its circumference. Drugs required for dispensing from the same prescription are thrown into the same drug storage space 42 by multiple dispensing devices. The drug storage spaces 42 can be separated by partitions 43, or they can be drug bottles or bags placed in preset positions. That is, during the operation of the conveyor belt, the drugs involved in the prescription will fall into the drug storage spaces 42, allowing the drugs for each prescription to be concentrated together, thereby achieving a streamlined dispensing process for different prescriptions and effectively improving dispensing efficiency.

[0058] Once each prescription is packaged in the packaging facility, the medicine bag can be transported to the dispensing staff via another conveyor belt. After verification, the dispensing staff can dispense the medicine to the patient.

[0059] like Figures 3-8As shown, in this embodiment, the dispensing device includes a bag feeding mechanism 100, a bag cutting mechanism 200, and a bag throwing mechanism 300. The bag feeding mechanism 100 includes a feeding belt 1 and a feeding belt 2 arranged opposite to each other. The feeding belt 1 and the feeding belt 2 drive a plurality of continuous packaging bags 400 containing materials to move between the feeding belt 1 and the feeding belt 2 in a first direction to transfer them to the bag cutting mechanism 200. The bag cutting mechanism 200 opens and closes in a second direction to cut the continuous packaging bags 400 into a planned number of packaging bags 400. The second direction is perpendicular to the first direction. The bag throwing mechanism 300 includes a roller 3 and a roller 4 arranged opposite to each other. The roller 3 and the roller 4 throw a planned number of packaging bags 400 out of the dispensing device between the roller 3 and the roller 4. The linear velocity of the packaging bag 400 moving between the feeding belt 1 and the feeding belt 2 is less than its linear velocity moving between the roller 3 and the roller 4.

[0060] In this embodiment, the first direction is the movement direction of the continuous packaging bag 400, and the second direction is the opening and closing direction of the bag cutting mechanism 200. Each packaging bag 400 contains medicine, and each bag 400 has a preset weight of medicine. Therefore, during the dispensing process, by obtaining the required amount of medicine in the prescription, the bag cutting mechanism 200 can cut the corresponding number of bags of medicine to meet the dispensing requirements. For example, if the prescription requires 10g of medicine A, and each packaging bag 400 contains 5g of medicine A, then the bag cutting mechanism 200 cuts two packaging bags 400 and throws them out through the bag throwing mechanism 300. If the prescription requires 5g of medicine A, then one packaging bag 400 is cut and thrown out.

[0061] There is a gap between the feeding belt 1 and the feeding belt 2. Continuous packaging bags 400 are clamped in the gap by the feeding belts 1 and 2, thereby causing the feeding belts 1 and 2 to move the packaging bags 400 forward using friction. A through-beam sensor and a color mark sensor are installed at the bag cutting mechanism 200. There is a transparent area between any two adjacent packaging bags 400. Each packaging bag 400 is equipped with a mark strip. The through-beam sensor detects the transparent area, and the color mark sensor detects the mark strip, thereby controlling the bag cutting mechanism 200 to cut the packaging bag 400. In addition, the through-beam sensor and / or the color mark sensor can also be used for counting, and the decision to cut the bag is made based on the count.

[0062] like Figure 8As shown, in this embodiment, the first roller 3 and the second roller 4 are made of silicone. When the packaging bag 400 is located between the first roller 3 and the second roller 4, the packaging bag 400 can be delivered effectively by utilizing friction. The first roller 3 is located below the second roller 4. The position of the second roller 4 can be changed in the second direction, while the first roller 3 has a fixed position. Therefore, the second roller 4 is dynamically adjustable in the second direction to adjust the relative distance between the first roller 3 and the second roller 4. The first roller 3 has a number of spaced protrusions 5 arranged along its circumference, and the protrusions 5 extend along the axis of the first roller 3. The bag throwing mechanism 300 has a housing 6, which has a groove 7. The roller 4 slides in the groove 7. Therefore, when the thickness of the packaging bag 400 changes, the roller 4 can achieve adaptive compression of the packaging bag 400. On this basis, since the roller 3 is provided with a protruding rib 5, when the linear velocity of the packaging bag 400 moving between the feeding belt 1 and the feeding belt 2 is less than its linear velocity moving between the roller 3 and the roller 4, the protruding rib 5 lifts the roller 4, and the planned number of packaging bags 400 are thrown out by taking advantage of the speed.

[0063] like Figure 6 , Figure 7As shown, in this embodiment, the bag-cutting mechanism 200 includes a fixedly disposed clamping member one and a clamping member two that can move toward or away from the clamping member one along a second direction; it also includes a driving member for driving the clamping member two to reciprocate along the second direction. Further, the clamping member two includes a connecting rod seat 8, a pressure block 9, a guide rod 10, and a cutter 11; the connecting rod seat 8 is connected to the driving member; one end of the guide rod 10 is fixedly connected to the pressure block 9, and the other end is slidably engaged with the connecting rod seat 8; an elastic element 12 is sleeved on the outer side of the guide rod 10; the cutter 11 is connected to the connecting rod seat 8 and located on one side of the pressure block 9; the clamping member one has a cutting groove 13 for engaging the cutter 11; the bag-cutting mechanism 200 also includes a guide rod 14, and the connecting rod seat 8 is slidably engaged with the guide rod 14 in the second direction. The driving component includes a second motor 15, with a motor connecting rod 16 connected to its free end. When the second motor 15 is started, the motor connecting rod 16 rotates around the axis of the free end of the second motor 15. The clamping component includes a base 17, which is provided with a cutting groove 13 for engaging the cutter 11. The driving component also includes a power connecting rod 18, whose two ends are connected to the motor connecting rod 16 and the connecting rod seat 8 respectively via fisheye bearings. Therefore, after the second motor 15 is started, the driving connecting rod seat 8 moves up and down relative to the base 17. When the through-beam sensor detects a corresponding number of transparent areas and the color mark sensor detects the mark strip of the corresponding packaging bag 400, the bag feeding mechanism 100 and the bag throwing mechanism 300 stop operating, and the pressing block 9, driven by the connecting rod seat 8, presses the packaging bag 400 tightly against the base 17. With the motor 15 running, one end of the guide rod 10 is fixedly connected to the pressure block 9, and the other end is slidably engaged with the connecting rod seat 8. An elastic element 12 is sleeved on the outer side of the guide rod 10. Therefore, when the pressure block 9 and the base 17 are pressed together, the elastic element 12 is compressed and deformed. The cutter 11 moves toward the cutting groove 13 and eventually extends into the cutting groove 13 to cut the packaging bag 400. As the motor 15 continues to operate, the power connecting rod 18 pulls the cutter 11 upward and withdraws it from the cutting groove 13.In actual use, the bag feeding mechanism 100 drives the packaging bag 400 past the cutter 11 mechanism and into the bag throwing mechanism 300. Since the speed of the packaging bag 400 at the bag throwing mechanism 300 is greater than that at the conveying mechanism, the speed difference between the two can stretch and straighten the packaging bag 400, thereby better avoiding the cutting misalignment of the packaging bag 400 caused by the cutter 11 mechanism. When the through-beam sensor detects the corresponding number of transparent areas and the color mark sensor detects the mark strip of the corresponding packaging bag 400, the bag feeding mechanism 100 and the bag throwing mechanism 300 stop rotating, and the cutter 11 mechanism cuts. After the cutting is completed, the bag feeding mechanism 100 and the bag throwing mechanism 300 are restarted, so that the preset number of packaging bags 400 in front of the cutter 11 are thrown out, thereby realizing the dispensing of medicines. The packaging bags 400 behind the cutter 11 pass over the cutter 11 mechanism and are straightened at the bag throwing mechanism 300. According to the actual prescription dispensing situation, the above process is repeated to realize the sequential dispensing of medicines in the prescription. When the next prescription does not require this type of medication, the packaging bag 400 behind the cutter 11 will not immediately enter the bag-throwing mechanism 300 due to the high speed at the bag-throwing mechanism 300. Therefore, while waiting for the next prescription dispensing, the planned number of packaging bags 400 can be fed to the bag-throwing mechanism 300 according to actual needs, and then the packaging bags 400 can be cut. In addition, the bag-feeding mechanism 100 is equipped with multiple sensors along its bag-feeding direction to detect whether the packaging bags are stuck during the conveying process. This setting can greatly improve the bag-feeding efficiency and reduce the failure rate of the device. When a sensor generates too many or too few signals, it indicates that the packaging bag 400 is stuck. At this time, the bag-feeding mechanism 100 reverses to retract the packaging bag 400, and then the bag-feeding mechanism 100 moves forward again to eliminate the problem of bag jamming. In special cases, the bag-feeding mechanism 100 can repeatedly retract and feed bags to meet the need to eliminate bag jamming. Specifically, the bag feeding mechanism 100 can use three sensors to determine whether the packaging bag 400 is stuck during the conveying process. That is, sensors are set at the front, middle and rear positions of the bag feeding mechanism 100. During the feeding or waiting to throw the bag, the relative position of each packaging bag 400 is detected. If a sensor generates too many or too few detection signals, it is determined that the bag is stuck or wrinkled. At this time, the packaging bag 400 is driven in reverse to move, so that the packaging bag 400 retracts and the bag feeding action is restarted, thereby eliminating the bag stuck or wrinkled situation.Furthermore, in this embodiment, the elimination of bag jamming or wrinkling is achieved through the reverse action of motor 28. Specifically, roller 3 is equipped with a one-way bearing, located at the end of the roller shaft, allowing the one-way bearing and the slide groove 7 to slide together. The one-way bearing ensures that roller 3 can only rotate in one direction. That is, when motor 28 drives the bag feeding mechanism 100 to reverse, roller 3 is stationary, enabling it to clamp the packaging bag 400 at the bag throwing mechanism 300, thus preventing the packaging bag 400 from getting stuck. One end is positioned, while the other end moves in the opposite direction with the bag feeding mechanism 100, thereby stretching the connected packaging bag 400. When the motor 28 drives the bag feeding mechanism 100 to move in the forward direction, the roller 3 rotates under the action of the motor 28. After cutting the packaging bag 400 according to the normal procedure, the packaging bag 400 is thrown out, thus effectively eliminating bag jamming and wrinkling during the feeding or waiting to throw bags. Of course, if there is no packaging bag 400 at the bag throwing mechanism 300, bag jamming and wrinkling can also be eliminated by relying solely on the reverse dragging of the bag feeding mechanism 100.

[0064] In this embodiment, pressure blocks 9 are provided on both sides of the cutter 11. That is, the pressure blocks 9 can press the packaging bag 400 on both sides of the cutter 11, thereby further improving the cutting stability and preventing the packaging bag 400 from sliding and failing to be cut due to the movement of the cutter 11. Furthermore, a serrated surface 19 is provided on the side of the pressure block 9 near the clamping member. The serrated surface 19 can increase the contact area between the pressure block 9 and the packaging bag 400, thereby better pressing the packaging bag 400 and better meeting the cutting requirements of the packaging bag 400.

[0065] like Figure 4 and Figure 5As shown, in this embodiment, the feed belt 1 has a driven cylinder 20 at its inlet and / or outlet ends. A shaft 21 passes through the driven cylinder 20, which rotates around the axis of the shaft 21. The driven cylinder 20 can move closer to or away from the feed belt 2 in a second direction. A recessed plane 22 is cut along the axis at the end of the shaft 21, and a floating component is connected to the recessed plane 22. Specifically, the bag feeding mechanism 100 has a housing 40. The floating component includes a floating rod 23, one end of which is fixedly connected to the recessed plane 22, and the other end is slidably engaged with the housing 40. An elastic element 24 is sleeved on the outer side of the floating rod 23. The feed belt 1 is located above the feed belt 2, and the feed belt 1 can reciprocate in the second direction, while the relative position of the feed belt 2 is fixed. The floating component can automatically adjust the bag feeding height. The floating rod 23 with elastic element 24 is connected to the shaft 21. The two ends of the shaft 21 are respectively connected to guide bearings 26. The housing 40 is provided with a sliding groove 27 so that the guide bearings 26 can float up and down in the sliding groove 27. By setting the adaptive floating component, the feeding belt 1 and feeding belt 2 can adhere and press the material during the feeding process, adapting to pharmaceutical packaging bags 400 of different thicknesses and irregularities. During the floating process, the shaft 21 itself does not rotate, but only reciprocates in the second direction. In this embodiment, the inlet and outlet ends of the feeding belt 1 are provided with driven cylinders 20. Therefore, it can achieve simultaneous floating on both sides of rising and falling, smoothly and without jamming, so as to better meet the transfer requirements of the packaging bag 400. In this embodiment, there is a gap between the guide bearing 26 and the second slide 27. During the process of floating according to the thickness of the packaging bag 400, only one side of the second slide 27 has sliding contact with the guide bearing 26, thereby reducing contact friction and improving the throughput efficiency of the packaging bag 400.

[0066] In this embodiment, the bag feeding mechanism 100 and the bag throwing mechanism 300 can be powered by different drive motors, or they can be powered by a single drive motor. Specifically, for example... Figures 3-5As shown, it also includes a motor 28, which has two branches: a power source and a power source. The power source is used to drive either the feeding belt 1 or the feeding belt 2. The feeding belt 1 and the feeding belt 2 are connected in a transmission relationship. The power source is used to drive the roller 3. The free end of the motor 28 is connected to an input shaft 29. One end of the input shaft 29 is connected to a synchronous pulley 30. Synchronous pulleys 31 and 32 are respectively arranged on both sides of the synchronous pulley 30. The roller 3 is connected to a synchronous pulley 33 via a roller shaft 25. Thus, through the multiple bends of the belt 34, the power is transmitted between the synchronous pulleys 30, 31, 32, and 33, thereby transmitting the power source 2 from the motor 28 to the roller 3, so as to throw the packaging bag 400 out of the dispensing device. This embodiment also includes a reducer 35, through which the power from the motor 28 is reduced and output. The feeding mechanism also includes a drive shaft 36. The feeding belt 1 is provided with an output shaft 37, and the feeding belt 2 is provided with an output shaft 38. In this embodiment, the drive shaft 36 is located inside the feeding belt 2 to optimize the assembly volume. One end of the drive shaft 36 meshes with a gear at the end of the output shaft 38, and the other end of the drive shaft 36 is connected to the end of the output shaft 37 via a belt 39, thereby realizing the rotation of the feeding belt 1 and the feeding belt 2. It should be noted that in this embodiment, the feeding belt 1 is tensioned and driven by the active cylinder connected to the output shaft 37 and the driven cylinder 20 connected to the two shafts 21. The power output of the output shaft 37 requires it to rotate around its own axis, while the two shafts 21 do not need to rotate around their own axes. By using bearings between the shafts 21 and the feeding belt 1, the overall rotation of the feeding belt 1 can be achieved.

[0067] The specific usage process of this embodiment is illustrated using a single package as an example. When using this embodiment, the small packaged herbal medicine bags 400 are input into the dispensing device and flattened. The small packaged herbal medicine bags 400 are conveyed forward, and a floating mechanism presses and closes the bags 400. When a photoelectric sensor detects the transparent area between two adjacent bags 400, and a color mark sensor detects the mark strip on the bag 400, the bag-cutting mechanism 200 drives the cutter 11 to cut the small packaged herbal medicine bags 400 into single packages. These single packages are then thrown out by a throwing mechanism, thereby reducing the workload of pharmacy dispensing personnel and effectively improving dispensing efficiency.

[0068] The above are merely preferred embodiments of the present invention. It should be noted that the above preferred embodiments should not be considered as limitations on the present invention, and the scope of protection of the present invention should be determined by the scope defined in the claims. For those skilled in the art, several improvements and modifications can be made without departing from the spirit and scope of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
