Abstract
Description
Technical Field
[0001] This utility model relates to the field of pharmaceutical dispensing equipment technology, and in particular to a semi-automatic dispensing device. Background Technology
[0002] In recent years, automated equipment has been gradually introduced into the decoction process of traditional Chinese medicine (TCM), enabling automatic weighing, decoction, slag removal, liquid delivery, and filling of medicinal materials, thus improving production efficiency and process controllability. However, the wide variety of TCM herbs and their significant differences in physicochemical properties, along with the instability of different herbs in terms of morphology, density, and hygroscopicity, place higher demands on the accuracy of ingredient addition. Currently, to ensure prescription integrity and medication safety, manual replenishment and verification are typically implemented in key processes of semi-dispensing equipment, relying on operators to visually or empirically verify the types and quantities of herbs already added to the dispensing tank. While this method ensures the accuracy of ingredient addition to a certain extent, it still suffers from low efficiency, susceptibility to subjective factors, and difficulty in real-time traceability. Especially in scenarios involving multiple varieties and small batches of personalized decoctions, effectively confirming that all TCM varieties and quantities are accurately in place after manual intervention, and avoiding omissions, incorrect additions, or duplicate additions, has become a key bottleneck restricting the quality control of automated TCM production.

[0060] Due to the wide variety of Chinese medicinal herbs and their significant differences in physicochemical properties, as well as the instability of different herbs in terms of morphology, density, and hygroscopicity, higher requirements are placed on the accuracy of ingredient addition. Currently, to ensure prescription integrity and medication safety, manual replenishment and verification are usually implemented in key processes of semi-dispensing equipment. This relies on operators to visually or empirically verify the types and quantities of herbs already added to the dispensing tank. While this method ensures the accuracy of ingredient addition to a certain extent, it still suffers from low efficiency, susceptibility to subjective factors, and difficulty in real-time traceability. Especially in scenarios involving multiple varieties and small batches of personalized decoctions, effectively confirming that all Chinese medicinal herbs have been accurately added after manual intervention, avoiding omissions, incorrect additions, or duplicate additions, has become a key bottleneck restricting the quality control of automated Chinese medicine production.
[0061] This utility model proposes a semi-automatic dispensing device 100, which aims to solve the problem of how to effectively confirm that all Chinese medicine varieties and quantities have been accurately delivered after manual intervention, and avoid omissions, incorrect dispensing or duplicate dispensing.
[0062] Please see Figures 1 to 3In one embodiment of this utility model, the semi-automatic dispensing equipment 100 includes a frame 1, a flow assembly 2, multiple conveying mechanisms 3, a manual dispensing device 4, a manual verification device 5, and a total verification mechanism 6. The frame 1 is equipped with a first feeding station a, a second feeding station b, a dispensing station c, a verification station d, and a total verification station e. The flow assembly 2 is used to sequentially convey the medicine barrel assembly 200 to the first feeding station a, the second feeding station b, and the total verification station e. The multiple conveying mechanisms 3 include a first conveying mechanism 31 and a second conveying mechanism 32 located on the frame 1. A conveying mechanism 31 is used to transport the medicine barrel assembly 200 between the dispensing station c and the first loading station a; a second conveying mechanism 32 is used to transport the medicine barrel assembly 200 between the second loading station b and the verification station d; a manual dispensing device 4 is used to manually dispense the Chinese medicinal materials in the medicine barrel assembly 200 transported to the dispensing station c; a manual verification device 5 is used to verify the Chinese medicinal materials in the medicine barrel assembly 200 transported to the verification station d; and a total verification mechanism 6 includes a weighing unit 61, which is used to weigh the medicine barrel assembly 200 located at the total verification station e.
[0063] Understandably, the frame 1 serves as the foundation for bearing and positioning, and is sequentially set along a preset path with a first loading station a, a second loading station b, a dispensing station c, a verification station d, and a total verification station e. Each station is arranged linearly or in a ring in space to ensure the orderly flow of the medicine barrel assembly 200 between the functional areas.
[0064] The first loading station a receives the medicine barrel assembly 200, which has already undergone partial automatic dispensing. This means that the upstream automated dispensing system initially adds a portion of the Chinese medicinal herbs to the medicine barrel according to the prescription information and dosage. The first loading station a corresponds to the dispensing station c, preparing for subsequent manual dispensing. The second loading station b corresponds to the verification station d, preparing for subsequent manual verification.
[0065] Dispensing station c is dedicated to manual replenishment or adjustment of medicinal materials within the 200-unit medicine container. Verification station d is used for visual or auxiliary verification of the condition of the medicinal materials after manual handling. Final verification station e is equipped with a high-precision weighing sensor for performing the final weight verification.
[0066] The flow assembly 2 serves as the power transmission system for the continuous movement of the medicine barrel assembly 200 between various workstations. It can employ chain drive, belt conveyor, or servo-driven rollers to ensure smooth and precise transport of the medicine barrel assembly 200 between the first loading station a, the second loading station b, and the final repetition station e. This assembly features position feedback, interacting with the control system via encoders or photoelectric sensors to ensure that each medicine barrel assembly 200 arrives at the designated station at the correct time.
[0067] The first conveying mechanism 31 and the second conveying mechanism 32 are respectively mounted on the frame 1. The first conveying mechanism 31 is usually a robotic arm or a linear module, used to realize the directional transfer of the medicine barrel assembly 200 between the dispensing station c and the first loading station a, so as to meet the loading requirements before manual dispensing. The second conveying mechanism 32 is responsible for transporting the medicine barrel assembly 200 after manual dispensing from the second loading station b to the verification station d. After verification, the medicine barrel assembly 200 is transported from the verification station d to the second loading station b.
[0068] The manual dispensing device 4 refers to the human-machine collaborative environment configured around the dispensing station c, including an operating table, lighting system, herbal medicine supply unit, and human-machine interface. Operators manually add any unadded or needing-to-be-replenished Chinese medicinal herbs to the medicine container component 200 by reading prescription information or system prompts, ensuring the integrity of the herbal medicine varieties and quantities.
[0069] The manual verification device 5 is installed at verification station d. At verification station d, the operator must carefully observe the type and quantity of medicinal materials in the medicine container assembly 200 to ensure that all medicinal materials have been accurately added. The operator uses their professional knowledge and experience, and directly visually inspects the color, shape, size, and other characteristics of the medicinal materials to determine whether they meet the prescription requirements.
[0070] After manual replenishment and verification, the medicine barrel assembly 200 is sent to the total repeat verification station e. The core of the total repeat verification mechanism 6 is the weighing unit 61, which uses a high-precision, anti-interference-capable weighing sensor (such as a strain gauge or electromagnetic force balance sensor) installed in the support structure of the total repeat verification station e to ensure that the total mass of the medicine barrel assembly 200 and its contents can be obtained quickly and stably after the dynamic conveying stops.
[0071] It should be noted that after the weighing unit 61 obtains the total weight of the medicine barrel assembly 200, the system automatically retrieves the pre-stored empty weight (tare weight) of the medicine barrel assembly 200 and deducts it from the total weight to obtain the net weight of the actual Chinese medicinal materials added. This net weight value is compared with the theoretical total weight calculated based on the type, weight, and quantity of each medicinal material in the prescription. If the deviation between the two is within the preset tolerance range, the verification is deemed successful; if it exceeds the tolerance, further inspection is required to compensate for subjective errors that may be caused by manual operation and to ensure the accuracy and consistency of the addition of each dose of Chinese medicine.
[0072] By setting up a multi-station collaborative semi-automatic dispensing device 100, an orderly connection between automated dispensing and manual replenishment and verification is achieved. Based on the completion of manual dispensing and visual verification, a final verification mechanism 6 is set up downstream of the flow assembly 2 as the final quality control inspection, which can improve the reliability of dispensing accuracy verification. The final verification mechanism 6 weighs the entire medicine barrel assembly 200 after replenishment. By using the weighing result as the final release basis, the limitations of manual operation and visual verification can be overcome, ensuring the accuracy and consistency of each dose of traditional Chinese medicine dispensing.
[0073] Specifically, please refer to Figures 3 to 4 In this embodiment, the water flow assembly 2 includes a conveyor frame 21, on which a conveyor section 22 is provided that is movably arranged along the extension direction of the conveyor frame 21. The medicine barrel assembly 200 is supported on the conveyor section 22. The total repeating core mechanism 6 is located below the conveyor section 22. The total repeating core mechanism 6 includes a first fixed base 62, a first driving device 63, and a first lifting part 64. The first fixed base 62 is fixedly connected to the conveyor frame 21. The first driving device 63 is installed on the first fixed base 62 and has a first driving part that can be moved up and down. The first lifting part 64 is connected to the top of the first driving part and is driven by the first driving part to move up and down. It is used to lift the medicine barrel assembly 200 during the upward movement to disengage it from the conveyor section 22. The weighing part 61 is provided on the first lifting part 64.
[0074] When the medicine barrel assembly 200 moves to the final weighing station e, the system accurately identifies its position using a position sensor (such as a photoelectric switch or proximity sensor) and triggers the weighing process. At this time, the final weighing mechanism 6, located directly below the conveying section 22, begins to operate. The final weighing mechanism 6 mainly includes a first fixed base 62, a first drive device 63, and a first lifting section 64.
[0075] The first fixed seat 62 is firmly connected to the bottom structure of the conveyor frame 21 by bolts or welding to ensure overall rigidity and stability and avoid measurement errors caused by deformation of the support during the weighing process.
[0076] The first drive unit 63 is mounted on the first fixed base 62 and can be a linear actuator such as a cylinder, electric push rod, or servo cylinder. Its output end is a first drive section that can reciprocate in the vertical direction (i.e., perpendicular to the conveying plane). The top of the first lifting section 64 is provided with a support surface that matches the bottom of the medicine barrel assembly 200. During the weighing process, the first drive unit 63 is activated, driving the first lifting section 64 to move upward, smoothly lifting the medicine barrel assembly 200 located directly above it from the conveying section 22, so that it is completely detached from the support of the conveying section 22.
[0077] The weighing unit 61 is integrated inside the first lifting unit 64 or its supporting structure. For example, it uses a high-precision strain gauge load cell to directly bear the entire weight of the medicine barrel assembly 200 and its contents transmitted by the first lifting unit 64. Since the medicine barrel assembly 200 is supported only by the weighing unit 61 during weighing, its weight signal can be accurately collected and transmitted to the control system. After obtaining the total weight, the control system automatically deducts the preset empty weight (tare weight) of the medicine barrel assembly 200, calculates the net weight of the medicinal materials, and compares it with the theoretical value of the prescription to complete the final verification.
[0078] By lifting the medicine barrel assembly 200 off the conveying section 22, the interference of the support structure of the conveying section 22 on the weight transfer path is eliminated, ensuring that the entire load is directly borne by the weighing section 61, thereby improving the accuracy of the weighing results.
[0079] Specifically, please refer to Figure 4 In this embodiment, the first fixed base 62 includes a first base plate 621 and a first guide sleeve 622. The first fixed base 62 is provided with a first guide hole 622a that passes through the first base plate 621 and the first guide sleeve 622 in a vertical direction. The bottom of the first lifting part 64 extends downward to form a first guide post 641, which passes through the first guide hole 622a to slide with the first guide hole 622a.
[0080] A first guide post 641 extends downward from the bottom of the first lifting part 64. This guide post has a cylindrical structure, and its outer diameter is slightly smaller than the inner diameter of the first guide hole 622a to achieve a clearance fit. In the assembled state, the first guide post 641 passes through the first guide hole 622a from bottom to top and can slide freely along the axis of the hole. A high-precision sliding pair is formed between the first guide post 641 and the first guide hole 622a, which effectively constrains the radial displacement and rotational degrees of freedom of the first lifting part 64 during the lifting process, ensuring that its movement trajectory is strictly along the vertical direction.
[0081] The guiding structure works in conjunction with the first driving device 63: when the first driving part (such as a cylinder piston rod or an electric push rod output shaft) pushes the first lifting part 64 upward, the first guide post 641 slides synchronously within the first guide hole 622a, playing a role in auxiliary guidance and anti-eccentric load. Even in the case of slight eccentricity of the driving force or uneven external load, this structure can still ensure that the medicine barrel assembly 200 is lifted smoothly and vertically, avoiding the influence of lateral force on the weighing sensor due to tilting or jamming, which would affect the measurement accuracy.
[0082] Further, please refer to Figures 3 to 4 In this embodiment, a positioning post 642 is provided on the top of the first lifting part 64. The positioning post 642 is used to position and cooperate with the positioning groove on the bottom plate of the medicine barrel assembly 200.
[0083] The base plate of the medicine barrel assembly 200 has a positioning groove at a corresponding position that matches the shape and size of the positioning post 642. This positioning groove can be a blind hole, through hole, or countersunk hole, and its inner wall forms a clearance fit or transition fit with the outer surface of the positioning post 642. When the medicine barrel assembly 200 moves with the conveying unit 22 to the total repeating core station e and is lifted upwards by the first lifting unit 64, the positioning post 642 simultaneously inserts into the positioning groove, achieving precise positioning of both in the horizontal plane. This configuration not only restricts the lateral displacement and rotational freedom of the medicine barrel assembly 200 relative to the first lifting unit 64 but also ensures that the center of gravity of the medicine barrel assembly 200 remains highly aligned with the loading axis of the weighing sensor.
[0084] By setting a positioning post 642 at the top of the first lifting part 64 and forming a positioning engagement with the positioning groove on the bottom plate of the medicine barrel assembly 200, the horizontal degree of freedom of the medicine barrel assembly 200 can be forcibly constrained, ensuring that it is always in the preset weighing position after being lifted away from the conveying part 22, avoiding uneven load distribution caused by swinging, offset or rotation, so as to improve the spatial positioning accuracy of the medicine barrel assembly 200 during the weighing process.
[0085] Specifically, please refer to Figure 4 In this embodiment, the first lifting part 64 includes a first lifting plate 643 and a second lifting plate 644 spaced apart in the vertical direction. The second lifting plate 644 is connected to the first driving part. The weighing part 61 has a first end and a second end that are arranged opposite to each other. The first end of the weighing part 61 is swayable in the vertical direction relative to the second end of the weighing part 61. The first end of the weighing part 61 is fixedly connected to the first lifting plate 643, and the second end of the weighing part 61 is fixedly connected to the second lifting plate 644. The first lifting plate 643 is used to lift the medicine barrel assembly 200.
[0086] The weighing unit 61 is a high-precision load cell with a first end and a second end arranged opposite to each other. The weighing unit 61 adopts a cantilever beam or double-end supported structure design. Its first end is fixedly connected to the first lifting plate 643 by bolts or elastic connectors, and its second end is fixedly connected to the second lifting plate 644. Crucially, the first end of the weighing unit 61 has a limited degree of freedom of swing in the vertical direction relative to its second end, allowing the first end to deflect at a small angle in the vertical plane, while the second end remains relatively fixed.
[0087] When the first drive device 63 is activated and pushes the second lifting plate 644 upward, the second lifting plate 644 drives the second end of the weighing part 61 to move upward synchronously, while the first lifting plate 643, under the weight of the medicine barrel assembly 200, generates a downward reaction force at the first end of the weighing part 61. Because the first end has the ability to swing, it can automatically adjust its posture during the lifting process of the medicine barrel assembly 200, ensuring that the weighing part 61 only responds to changes in load in the vertical direction and is not affected by lateral forces or bending moments.
[0088] Specifically, please refer to Figure 5 , Figure 6 and Figure 8 In this embodiment, the adjustment station c and the first loading station a are arranged at intervals in the longitudinal direction, and the verification station d and the second loading station b are arranged at intervals in the longitudinal direction. The conveying mechanism 3 includes a second fixed base 301, a second driving device 302, a second lifting part 303, and a conveying part 304. The second fixed base 301 is fixedly connected to the conveying frame 21. The second driving device 302 is installed on the second fixed base 301 and has a second driving part that is movably arranged in the vertical direction. The second lifting part 303 is connected to the second driving part and is driven by the second driving part to move in the vertical direction. It is used to lift the medicine barrel assembly 200 in the upward movement stroke to disengage it from the conveying part 22. The conveying part 304 is movably arranged in the longitudinal direction on the second lifting part 303. The conveying part 304 is used to transport the medicine barrel assembly 200 at the first loading station a from the first loading station a to the dispensing station c, or to transport the medicine barrel assembly 200 at the second loading station b from the second loading station b to the verification station d.
[0089] The second fixed seat 301 is fixedly connected to the side or bottom structure of the conveyor frame 21, serving as the supporting foundation for the entire conveying mechanism 3.
[0090] The second drive unit 302 is mounted on the second fixed base 301 and can be a pneumatic, electric or hydraulic actuator. Its output end is a second drive unit that can reciprocate in the up-down (vertical) direction.
[0091] The second lifting part 303 is connected to the top of the second drive part and can be lifted and lowered vertically under the drive of the second drive part. It is used to lift the medicine barrel assembly 200 located at the first loading station a or the second loading station b from the conveying part 22 during the upward stroke, so that it is completely separated from the support of the main conveying system and achieves mechanical decoupling.
[0092] Once the medicine barrel assembly 200 is lifted to a predetermined height by the second lifting part 303, its entire weight is borne by the second lifting part 303. At this time, the main conveying part 22 can continue to operate without affecting the state of the medicine barrel assembly 200.
[0093] The conveyor unit 304 is longitudinally movably mounted on the second lifting unit 303, for example, using a synchronous belt / screw drive system driven by a linear guide rail, servo motor, or stepper motor. Upon receiving a control command, the conveyor unit 304 starts, moving the medicine barrel assembly 200 it carries longitudinally, precisely transporting it from the first loading station a to the dispensing station c, or from the second loading station b to the verification station d. After this process is completed, the second lifting unit 303 lowers, repositioning the medicine barrel assembly 200 onto the support surface of the target station, and the conveyor unit 304 resets, ready for the next transfer operation.
[0094] Specifically, please refer to Figure 8 In this embodiment, the conveying mechanism 3 further includes a third driving device 305, a drive shaft 306, a second drive wheel 307 and a third drive wheel 308, a first drive belt 309, a first tension wheel 310 and a second tension wheel 311, and a second drive belt 312. The third driving device 305 has an output shaft extending laterally, and the output end of the output shaft is coaxially connected to the first drive wheel. The drive shaft 306 extends laterally and is spaced longitudinally from the output shaft, and is rotatably arranged about its axis. The second drive wheel 307 and the third drive wheel 308 are coaxially connected to the drive shaft 306. The first drive belt 309 is wound around the periphery of the first drive wheel and the second drive wheel 307 to drive the first drive wheel and the second drive wheel 307. The first tension wheel 310 and the second tension wheel 311 are spaced longitudinally and are rotatably connected to the second lifting part 303 about a laterally extending axis of rotation. The second transmission belt 312 is wound around the periphery of the third transmission wheel 308, the first tension wheel 310 and the second tension wheel 311 to drive the third transmission wheel 308 and the first tension wheel 310 and the second tension wheel 311. The second transmission belt 312 includes a transmission section 304.
[0095] The third drive unit 305 is the power source, typically a servo motor or a stepper motor. It is mounted on the second lifting part 303, and its output shaft extends laterally (i.e., in the left-right direction of the equipment, consistent with the main conveying direction). The output end of this output shaft is coaxially connected to the first transmission wheel, which serves as the power input end, transmitting the rotational motion of the motor to the subsequent transmission components.
[0096] The drive shaft 306 is arranged parallel to the output shaft, extending laterally and maintaining a certain distance from the output shaft in the longitudinal direction, forming a staggered layout. The drive shaft 306 is rotatably mounted on the second lifting part 303 via bearing seats or bushings, possessing good rotational freedom and radial support rigidity. A second drive wheel 307 and a third drive wheel 308 are coaxially and fixedly connected to the drive shaft 306, located at either end or at appropriate positions on the drive shaft 306, respectively, to distribute the rotational motion of the drive shaft 306 to different transmission paths.
[0097] The first transmission belt 309 is a synchronous belt or a flat belt, which is wound around the periphery of the first transmission wheel and the second transmission wheel 307 to form a closed loop and realize synchronous transmission between the two wheels. When the third drive device 305 is started, the power drives the first transmission wheel to rotate through the output shaft, and drives the second transmission wheel 307 and the coaxial transmission shaft 306 to rotate synchronously through the first transmission belt 309, thereby transmitting the power to the third transmission wheel 308.
[0098] To achieve longitudinal conveying, the second drive belt 312 is wound around the periphery of the third drive pulley 308, the first tension pulley 310, and the second tension pulley 311, forming another closed transmission circuit. The first tension pulley 310 and the second tension pulley 311 are spaced apart in the longitudinal direction, and their rotation axes extend laterally. They are rotatably connected to the second lifting part 303 via bearings to support the second drive belt 312 and adjust its tension. The upper belt body of the second drive belt 312 extends longitudinally, and its outer surface directly supports and drives the movement of the medicine barrel assembly 200. Therefore, this part of the belt body constitutes the conveyor part 304.
[0099] When the third drive wheel 308 rotates with the drive shaft 306, it drives the second drive belt 312 to circulate. Its upper belt moves smoothly in the longitudinal direction (from front to back or from back to front), thereby pushing the medicine barrel assembly 200 from the first feeding station a to the dispensing station c, or from the second feeding station b to the verification station d.
[0100] Through the synergistic effect of two-stage belt drives, the transverse rotational motion is efficiently converted into longitudinal linear conveying, resulting in a simple structure and stable operation. In particular, after the medicine barrel assembly 200 is lifted off the main conveying section 22 by the second lifting section 303, the conveying section 304 can complete precise longitudinal transfer at an independent height, thus avoiding interference with the main conveying system.
[0101] Further, please refer to Figure 8 In this embodiment, the second fixed base 301 includes a second base plate 3011 and a second guide sleeve 3012. The second fixed base 301 is provided with a second guide hole that passes through the second base plate 3011 and the second guide sleeve 3012 in a vertical direction. The bottom of the second lifting part 303 extends downward to form a second guide post 3031, which passes through the second guide hole to slide with the second guide hole.
[0102] The bottom of the second lifting part 303 extends downwards into a cylindrical second guide post 3031, which is typically made of high-strength alloy steel and has been hardened or plated to improve wear resistance. During assembly, the second guide post 3031 is inserted into the second guide hole from bottom to top, forming a precise sliding fit with the hole wall. The second guide hole penetrates the second seat plate 3011 and the second guide sleeve 3012 of the second fixed seat 301, forming a vertical guide reference.
[0103] When the second drive unit 302 (such as a cylinder or electric actuator) drives the second drive section to move up and down, power is transmitted to the second lifting section 303, causing it to rise and fall as a whole. During this process, the second guide column 3031 slides synchronously within the second guide hole, playing a guiding and anti-eccentric load role. Even if there is a slight eccentricity in the driving thrust or uneven external load, this structure can effectively limit the lateral displacement and rotation of the second lifting section 303, ensuring that it moves along a strictly vertical trajectory and preventing structural wear or functional abnormalities caused by tilting or jamming.
[0104] To reduce friction and improve durability, a self-lubricating bushing or linear bearing can be embedded in the second guide sleeve 3012 to provide reliable mechanical support for the stable operation of the conveyor 304 during the lifting process, and to ensure the smoothness and positioning accuracy of the transfer of the medicine barrel assembly 200.
[0105] Further, please refer to Figure 7 In this embodiment, the automatic dispensing equipment further includes a fourth driving device 7 and a stop part 8. The fourth driving device 7 is fixedly installed on the flow assembly 2 and has a fourth driving part that is movably arranged in the vertical direction. The stop part 8 is connected to the fourth driving part and is driven by the fourth driving part to move in the vertical direction. The stop part 8 is used to limit and stop the medicine barrel assembly 200 when the flow assembly 2 conveys the medicine barrel assembly 200 to the first feeding station a, the second feeding station b, or the total repeating station e.
[0106] The fourth drive device 7 is a linear actuator, which can be a cylinder, an electric push rod, or a servo cylinder. Its main body is fixedly installed on the side or bottom of the conveyor frame 21 of the flow assembly 2, and the installation position corresponds to the stopping area of the first loading station a, the second loading station b, and the total repeating station e. The output end of the fourth drive device 7 is a fourth drive unit that can reciprocate in the up-down direction (i.e., the vertical direction).
[0107] The stop 8 is connected to the end of the fourth drive unit and is configured as a stop or pin that can be raised and lowered vertically. When the medicine barrel assembly 200 moves with the conveyor 22 of the flow assembly 2 to the target station (such as the first loading station a, the second loading station b, or the total repeat verification station e), the system identifies its arrival signal through a photoelectric sensor or encoder, and then triggers the fourth drive unit 7 to move upward, extending from below or to the side of the conveying path to form a physical block, preventing the medicine barrel assembly 200 from continuing to move forward, thus achieving precise positioning and stopping. After completing the operation at this station (such as manual replenishment, verification, or weighing), the fourth drive unit drives the stop 8 downward to retract, leaving the conveying path, releasing the limit, and allowing the medicine barrel assembly 200 to continue to be conveyed to the next station.
[0108] Further, please refer to Figure 9 and Figure 10In this embodiment, the automatic dispensing equipment also includes a first limiting part 91 disposed on the flow assembly 2. The first limiting part 91 is disposed on the side of the flow assembly 2 in the longitudinal direction and away from the manual dispensing device 4, and is used to stop and limit the medicine barrel assembly 200 at the first feeding station a when the medicine barrel assembly 200 is transported from the self-dispensing station c to the first feeding station a.
[0109] It should be noted that "longitudinal" refers to the front and rear axis perpendicular to the main conveying direction, and "the side away from the manual dispensing device 4" is the end side of the medicine barrel assembly 200 when it returns from the dispensing station c to the first loading station a, which is usually the outer edge area of the conveying path.
[0110] The first limiting part 91 can be a fixed stop or an elastic buffer structure, installed at the downstream end of the first loading station a (i.e., the end point of the return path of the medicine barrel assembly 200). When the medicine barrel assembly 200 completes the operation at the dispensing station c, it is transported longitudinally from the dispensing station c to the first loading station a by the conveying part 304 in the conveying mechanism 3, and its movement trajectory terminates at the predetermined stopping point of the first loading station a. At this time, the first limiting part 91 acts as a physical limiting element, preventing the medicine barrel assembly 200 from continuing to move longitudinally, forcing it to stop at a precise position aligned with the main conveying part 22, thus achieving positioning and limiting.
[0111] For further information, please refer to [link / reference]. Figure 9 and Figure 10 In this embodiment, the automatic dispensing equipment also includes a second limiting part 92 disposed on the flow assembly 2. The second limiting part 92 is disposed on the side of the flow assembly 2 in the longitudinal direction and away from the manual verification device 5. It is used to stop and limit the medicine barrel assembly 200 at the second feeding station b when the medicine barrel assembly 200 is transported from the verification station d to the second feeding station b.
[0112] Thus, when the medicine barrel assembly 200 completes manual visual verification at the verification station d, it is transported longitudinally from the verification station d to the second loading station b by the conveying part 304 of the conveying mechanism 3. Its movement trajectory terminates at the predetermined stopping point of the second loading station b. At this time, the second limiting part 92 acts as a terminal mechanical limiting element, preventing the medicine barrel assembly 200 from continuing to move and forcing it to stop at a precise position aligned with the main conveying part 22, thereby achieving positioning and limiting.

Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
