Description

Technical Field

[0001] This invention belongs to the field of material preparation technology, specifically relating to a preparation system and control method suitable for preparing granular preparations and powders, and the preparation system and control method are particularly suitable for preparing Mongolian medicines. Background Technology

[0002] The dispensing system integrates functional modules such as bag feeding, dispensing, top sealing, and bag dropping, enabling it to complete the entire process from drug bag supply to formulation packaging and dispensing. For example, Chinese invention patent application number CN202110394997.3 discloses a dispensing system for granular products. However, traditional dispensing systems generally only have a single bag feeding station and a corresponding bag-making device. This bag-making device can only produce a single type of drug bag and cannot adapt to the simultaneous dispensing needs of different formulation combinations. It is especially unsuitable for scenarios such as Mongolian medicine, where different formulation combinations need to be taken at different times, which can easily lead to confusion in the subsequent sorting process.

[0003] Taking Mongolian medicine dispensing as an example, Mongolian medicine has a unique prescription feature of "three doses a day + medicinal guide." This means that the Mongolian medicine a patient needs to take daily must be prepared separately for three doses—morning, noon, and evening—along with a dedicated medicinal guide. Furthermore, the three doses and the medicinal guide must be packaged separately to ensure accurate administration. Traditional dispensing systems lack effective visual differentiation methods. The medicine bags containing the three doses and the medicinal guide prepared using such systems are difficult to distinguish visually, easily leading to confusion during subsequent sorting. This can result in patients taking the wrong dose or missing a dose, severely impacting the treatment effect.

[0004] If only one traditional dispensing system is used for dispensing Mongolian medicine, operators need to frequently change the bag-making raw materials to adapt to the needs of visually distinguishable medicine bag preparation. This will not only seriously interrupt the dispensing process, but may also cause system errors and shutdowns due to frequent parameter adjustments, significantly reducing dispensing efficiency. If multiple independent dispensing systems are configured to adapt to the needs, with each system preparing a corresponding type of medicine bag and handling the corresponding combination preparation, it will greatly increase the site occupation cost and equipment purchase and operation costs. Moreover, it is difficult for multiple systems to achieve collaborative operation, which is not conducive to the intensive management of the production line.

[0005] In view of this, the present invention is proposed. Summary of the Invention

[0006] This invention provides a dispensing system and control method, aiming to solve the problem that existing dispensing systems, when dispensing different formulation combinations simultaneously, are prone to confusion in the subsequent sorting process due to the lack of effective visual differentiation methods.

[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows: a dispensing system, including a transmission module, on which a medicine bag holding mechanism for carrying medicine bags is installed; the dispensing system is configured with a bag-giving station, a dispensing station, a top-sealing station, and a bag-dropping station along the extension path of the transmission module; multiple bag-giving stations are configured, and a bag-making device is respectively set below each bag-giving station; the bag-making devices below the multiple bag-giving stations push the produced medicine bags into the corresponding medicine bag holding mechanism at the bag-giving station, for receiving combination preparations of different formulations at the dispensing station; the medicine bags produced by the bag-making devices below the multiple bag-giving stations are easy to distinguish.

[0008] Furthermore, the bags produced by the bag-making devices below different bag-feeding stations are of different colors; and / or, the bags produced by the bag-making devices below different bag-feeding stations are respectively provided with indicator marks of different shapes and / or colors.

[0009] Furthermore, different formulations of combined preparations are used for the same patient to take at different times; the number of bag-giving stations is greater than or equal to the number of times of administration, and less than or equal to the number of types of combined preparations.

[0010] Furthermore, the dispensing system categorizes medicine bags according to the medication time period; a medicine bag receiving device is installed below the bag-dropping station, the medicine bag receiving device includes multiple receiving containers, the medicine bag receiving device is configured to receive control signals, and classify and receive medicine bags according to the classification information of the medicine bags through multiple receiving containers; preferably, the number of receiving containers is the same as the number of medication time periods, and multiple receiving containers are used to receive medicine bags for different medication time periods.

[0011] Furthermore, the combination formulations with different formulations include a first combination formulation and a second combination formulation, which are used for the same patient to take the medication in multiple doses during the same medication period; the bag-dispensing station includes: a first bag-dispensing station, which has multiple bag-making devices as many as the number of medication periods, and bag-making devices below the multiple first bag-dispensing stations are used to prepare various easily distinguishable first drug bags, which are used to receive the first combination formulations for different medication periods; a second bag-dispensing station, which has one, and bag-making devices below the second bag-dispensing station are used to prepare second drug bags, which are used to receive the second combination formulations for different medication periods; the first drug bags and second drug bags corresponding to the same medication period are received by the same receiving container.

[0012] Furthermore, it also includes a label printing module, located near the medicine bag dispensing outlet on the outer shell of the dispensing system; the label printed by the label printing module is used to indicate at least the medication period, and the label is fixed to at least the second medicine bag; preferably, a rejection station is provided between the bag-giving station and the dispensing station, the rejection station is equipped with a bag-opening mechanism, a bag-opening support mechanism and a bag-dropping mechanism, and a bag-opening detection module for identifying whether the bag opening of the medicine bag is fully opened is located above the bag-giving station and / or above the rejection station.

[0013] Furthermore, multiple medicine bag holding mechanisms are evenly arranged along the extension path of the transmission module; the distance between two adjacent bag feeding stations is the same as the distance between two adjacent medicine bag holding mechanisms; preferably, the extension path of the transmission module is a closed loop, driving the medicine bag holding mechanism to circulate between the bag feeding station, the dispensing station, the top sealing station, and the bag dropping station; a support rail parallel to the extension path of the transmission module is provided on one side of the transmission module where the medicine bag holding mechanism is installed; the first side of the medicine bag holding mechanism is connected to the transmission module, and the second side of the medicine bag holding mechanism is provided with a support wheel, which abuts against the support rail and rolls along the support rail.

[0014] Furthermore, the transmission module includes multiple long, straight transmission sections, and multiple dispensing stations are evenly arranged along at least a portion of the transmission sections. The distance between two adjacent dispensing stations on the same transmission section is the same as the distance between two adjacent medicine bag holding mechanisms. Preferably, the dispensing module includes multiple dispensing cabinets for quantitatively dispensing different types of materials. At least two dispensing cabinets are grouped close to each other, and each group of powder dispensing cabinets corresponds to a converging pipe. A dispensing station is formed below each converging pipe.

[0015] The present invention also provides a control method for the above-mentioned dispensing system, comprising the following steps: S1: Host computer receives and processes data; S2: The medicine bag holding mechanism moves to the bag feeding station, and multiple bag making devices work to push the produced medicine bags into the corresponding medicine bag holding mechanism at the bag feeding station; S3: The host computer classifies the medicine bags prepared by different bag-making devices; S4: The medicine bag holding mechanism passes through multiple dispensing stations in sequence. The host computer controls the dispensing module to output the matching material into the medicine bag according to the prescription and the classification information of the medicine bag. S5: When the medicine bag holding mechanism moves to the top sealing station, the host computer controls the top sealing device to seal the medicine bag; S6: When the medicine bag holding mechanism moves to the bag dropping station, it classifies and accepts the medicine bags according to their classification information.

[0016] Preferably, the host computer obtains the position of the medicine bag holding mechanism through the photoelectric position detection component; the dispensing system is also equipped with a transmission verification module. When the dispensing system restarts after a work malfunction, the host computer determines whether the code of the medicine bag holding mechanism currently in the bag dropping position is correct through the identification information of the transmission verification module; if the code of the medicine bag holding mechanism currently in the bag dropping position is incorrect, the transmission module is controlled to reset.

[0017] Furthermore, when a single patient needs to take the same combination of medications at different times, the prescriptions for multiple patients are adjusted simultaneously, and the host computer uses the patient's identity information as the classification information for the medicine bag; when a single patient needs to take the same combination of medications at different times, the prescriptions for multiple different times for that patient are adjusted simultaneously, and the host computer uses at least the medication time information as the classification information for the medicine bag. Preferably, in step S1, the host computer determines the number of bag-dispensing stations M = m + n - 1 based on the number m of medication periods in the prescription and the number n of the combined preparations for each medication period; when n > 1, in step S3, the host computer uses the medication period information and preparation type information as the classification information for the medicine bags; in step S6, the host computer classifies and accepts the medicine bags according to the medication period information; preferably, at least when n > 1, when medicine bags are taken out from the same receiving container, labels are affixed to the easily distinguishable multiple medicine bags, and the labels contain medication period information and medication order information.

[0018] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0019] 1. By configuring multiple bag-giving stations and corresponding bag-making devices, this invention can prepare a variety of easily distinguishable medicine bags. This allows for intuitive differentiation of different formulation combinations, especially clearly distinguishing the morning, noon, and evening doses of Mongolian medicine and the guiding agent, avoiding confusion during subsequent sorting, ensuring accurate administration to patients, guaranteeing medication safety and therapeutic effect, and improving dispensing efficiency and operational continuity.

[0020] 2. The medicine bag receiving device of the present invention receives medicine bags for different medication periods separately through multiple receiving containers, which can effectively avoid the risk of mis-taking and confusion during the manual sorting process, further improve the accuracy of medicine bag sorting and medication safety, and significantly enhance the intelligence level of the dispensing system.

[0021] 3. By setting up a label printing module, the present invention enables patients to further distinguish the medicine bags according to the label, and forms a double distinction with the color and / or indication on the medicine bag to avoid wrong dosage.

[0022] 4. By providing support rails at intervals on the side of the transmission module and providing support wheels on the medicine bag holding mechanism that cooperate with the support rails, the present invention can improve the support effect on the medicine bag holding mechanism and keep the medicine bag holding mechanism in a horizontal state at all times.

[0026] It should be noted that these accompanying drawings and textual descriptions are not intended to limit the scope of the invention in any way, but rather to illustrate the concept of the invention to those skilled in the art by referring to specific embodiments. Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0028] In the description of this invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0029] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0030] like Figure 1 As shown in the embodiments of the present invention, a dispensing system is introduced for dispensing materials such as granular formulations and powders.

[0031] The dispensing system includes a transmission module 5, on which a medicine bag holding mechanism 4 for carrying medicine bags 40 is installed. The dispensing system is configured with a bag feeding station, a dispensing station, a top sealing station 5-2, and a bag dropping station 5-3. When the transmission module 5 is working, it drives the medicine bag holding mechanism 4 installed on it to move, so that the medicine bag holding mechanism 4 passes through the bag feeding station, the dispensing station, the top sealing station 5-2, and the bag dropping station 5-3.

[0032] Below the bag-feeding station is a bag-making device 2-0, which is used to prepare medicine bags 40 and push them into the medicine bag holding mechanism 4. Specifically, the space for accommodating the medicine bags on the medicine bag holding mechanism 4 extends vertically through the mechanism. When the medicine bag holding mechanism 4 moves to the bag-feeding station, the medicine bag 40 enters the mechanism from the bottom. The mechanism then squeezes the two sides of the medicine bag 40, opening the top of the bag. After entering, the bag is in an open state.

[0033] A dispensing module 1 is installed above the dispensing station. The dispensing module 1 includes multiple dispensing cabinets 10. Each dispensing cabinet 10 has a hopper 11 containing different types of materials, which can be powders or granules of traditional Chinese medicine or Mongolian medicine. The dispensing cabinet 10 is used to quantitatively dispense the materials stored in its hopper 11. A dispensing station is formed at the bottom of the dispensing module 1. When the medicine bag holding mechanism 4 moves to the dispensing station, the dispensing cabinet 10 operates, conveying a quantitative amount of material into the medicine bag 40.

[0034] A top sealing device is installed at the top sealing station 5-2. When the medicine bag holding mechanism 4 moves to the top sealing station 5-2, the top sealing device heat seals the top opening of the medicine bag 40.

[0035] Below the bag dropping station 5-3, there is a medicine bag receiving device 1-0. When the medicine bag holding mechanism 4 moves to the bag dropping station 5-3, the bag pressing block of the medicine bag holding mechanism 4 opens, and the medicine bag 40 detaches from the bottom of the medicine bag holding mechanism 4 and falls into the receiving container 1-3 of the medicine bag receiving device 1-0.

[0036] This embodiment aims to address the problem in existing dispensing systems where the simultaneous dispensing of different formulation combinations is prone to confusion during subsequent sorting due to the lack of effective visual differentiation methods. In this embodiment, "simultaneous dispensing" specifically refers to the dispensing system completing the dispensing of multiple different formulation combinations within one work cycle.

[0037] like Figure 1 and Figure 2 As shown in this embodiment, multiple bag-feeding stations are configured, and a bag-making device 2-0 is respectively installed below each bag-feeding station. The bag-making devices 2-0 below the multiple bag-feeding stations can produce different types of medicine bags 40. The different types of medicine bags 40 produced by the different bag-making devices 2-0 have the characteristic of being easily distinguishable, that is, the medicine bags 40 produced by the bag-making devices 2-0 below the multiple bag-feeding stations are easily distinguishable. The bag-making devices 2-0 below the multiple bag-feeding stations push the produced medicine bags 40 into the corresponding medicine bag holding mechanism 4 at the bag-feeding station, for receiving combination preparations of different formulations at the dispensing station.

[0038] In this embodiment, the "combination formulations with different formulations" are specifically combination formulations composed of materials of different types and / or weights. That is, the components of combination formulations with different formulations are different, and the types and weights of materials required for each combination formulation are obtained from the prescription.

[0039] In this embodiment, the medicine bags 40 produced by the bag-making devices 2-0 below different bag-giving stations are of different colors; and / or, the medicine bags 40 produced by the bag-making devices 2-0 below different bag-giving stations are respectively provided with indicator marks of different shapes and / or colors. Thus, sorting personnel and patients can intuitively distinguish different formulation combinations, especially making the dispensing system suitable for simultaneously dispensing different formulation combinations. Specifically, when dispensing Mongolian medicine and other formulation combinations that require different dosages at different times, the dispensing system can utilize easily distinguishable medicine bags 40 produced by the bag-making devices 2-0 below multiple bag-giving stations to receive and package different formulation combinations, avoiding confusion during subsequent sorting, ensuring accurate patient administration (e.g., enabling operators to clearly distinguish the morning, noon, and evening doses of Mongolian medicine and the accompanying medicine), ensuring medication safety and therapeutic effect, while improving dispensing efficiency and operational continuity.

[0040] like Figure 3 As shown, in some specific embodiments, the bag-making device 2-0 includes a film roll support and feeding mechanism 2-1, a sealing and cutting mechanism 2-2, and a film feeding mechanism 2-5. The film roll support and feeding mechanism 2-1 is used to support the film roll 2-6 and convey the pre-folded film 2-61; the sealing and cutting mechanism 2-2 includes a sealing and cutting mechanism bracket 2-21 disposed above the film roll support and feeding mechanism 2-1, and a sealing and cutting execution component mounted on the sealing and cutting mechanism bracket 2-21. The sealing and cutting execution component is used to vertically seal the pre-folded opposite side of the pre-folded film 2-61, and to horizontally seal and cut the vertically sealed pre-folded film 2-61; the film feeding mechanism 2-5 is used to convey the pre-folded film 2-61, and the film feeding mechanism 2-5 can convey the film roll support and feeding mechanism 2-1 into the sealing and cutting mechanism 2-2 for vertical sealing, horizontal sealing, and cutting.

[0041] The membrane roll support and feeding mechanism 2-1 includes a membrane roll support and feeding mechanism bracket 2-11, and a membrane roll support assembly 2-12, a membrane unwinding assembly 2-13, a membrane shaping assembly 2-14, and a membrane guide roller 2-15 mounted on the membrane roll support and feeding mechanism bracket 2-11. The pre-folded membrane 2-61 passes through the membrane unwinding assembly 2-13 and the membrane shaping assembly 2-14 in sequence. Multiple membrane guide rollers 2-15 are arranged between the membrane roll support assembly 2-12 and the membrane unwinding assembly 2-13 and / or between the membrane unwinding assembly 2-13 and the membrane shaping assembly 2-14 for the pre-folded membrane 2-61 to pass through. The membrane roll support assembly 2-12, the membrane unwinding assembly 2-13, and the membrane shaping assembly 2-14 are all independent modules.

[0042] The membrane roll support assembly 2-12 is used to support the membrane roll 2-6 and is a separate module.

[0043] The film unwinding assembly 2-13 is an independent module, including an unwinding traction structure 2-131 and a floating roller group 2-132. The unwinding traction structure 2-131 is used to clamp the pre-folded film 2-61 and drive the pre-folded film 2-61 to unwind from the film roll 2-6. The floating roller group 2-132 is located below the unwinding traction structure 2-131 and is used to balance the traction force of the pre-folded film 2-61.

[0044] The membrane shaping component 2-14 is located upstream of the membrane feeding mechanism 2-5. It is used to weaken the pre-folded side fold of the pre-folded membrane 2-61, realize pre-shaping, and make it easier for the drug bag 40 to open in the drug bag holding mechanism 4.

[0045] The pre-folded film 2-61 is provided with color mark areas evenly arranged along its length. A color mark sensor 2-16 is provided between two adjacent film guide rollers 2-15. The color mark sensor 2-16 is electrically connected to the film feeding mechanism 2-5. By detecting the color mark areas on the pre-folded film 2-61, the feeding amount of the pre-folded film 2-61 is controlled to ensure the consistency of the length of the medicine bag 40.

[0046] A U-shaped sensor 2-17 is also installed between two adjacent film guide rollers 2-15 to detect the presence of pre-folded film 2-61. Specifically, the U-shaped sensor 2-17 can be a light sensor. The U-shaped sensor 2-17 is located below the color mark sensor 2-16 and is used to issue a no-film alarm signal when the pre-folded film 2-61 on the film roll 2-6 is used up.

[0047] The sealing and cutting mechanism support 2-21 includes a first support wall 2-211 and a second support wall 2-212 arranged opposite to each other. The sealing and cutting execution assembly includes a sealing and cutting feed assembly 2-23, a vertical sealing assembly, a horizontal sealing assembly, and a cutter. The sealing and cutting feed assembly 2-23 includes a first sealing and cutting feed support plate 2-231, a second sealing and cutting feed support plate 2-232, a first sealing and cutting feed guide structure 2-233, a second sealing and cutting feed guide structure 2-234, and a sealing and cutting feed drive structure. The first sealing and cutting feed support plate 2-231 is mounted on the second support wall 2-212 via the first sealing and cutting feed guide structure 2-233, and the second sealing and cutting feed support plate 2-232 is mounted on the first sealing and cutting feed support plate 2-231 via the second sealing and cutting feed guide structure 2-234. The motor of the sealing and cutting feed drive structure is mounted on the second support wall 2-212 via a motor bracket, and is connected to the first sealing and cutting feed support plate 2-231 via a gear and rack transmission structure. A compression spring is provided between the first sealing and cutting feed support plate 2-231 and the second sealing and cutting feed support plate 2-232 to keep them away from each other.

[0048] The vertical sealing assembly includes a vertical sealing strip and a corresponding vertical sealing block. The horizontal sealing assembly includes a horizontal sealing strip and a corresponding horizontal sealing block. The second sealing and cutting feed support plate 2-232 is positioned opposite to the first support wall 2-211. The vertical and horizontal sealing strips are fixed to the second sealing and cutting feed support plate 2-232, and the vertical and horizontal sealing blocks are mounted on the first support wall 2-211. The cutter of the sealing and cutting execution assembly is fixed to the first sealing and cutting feed support plate 2-231. The second sealing and cutting feed support plate 2-232 has an opening corresponding to the cutter for the cutter to pass through.

[0049] In this embodiment, the horizontal sealing component is positioned above the vertical sealing component, and the horizontal sealing component and the vertical sealing component simultaneously seal the bottom of one medicine bag 40 and the side of the next adjacent medicine bag 40. That is, for the production of a medicine bag 40, one stroke of the sealing and cutting feed component 2-23 of the sealing and cutting execution component can seal the opposite side of the pre-folded side of the pre-folded film 2-61. At this time, the position of the pre-folded film 2-61 corresponding to the medicine bag 40 forms a cylindrical structure. Then, the sealing and cutting feed component 2-23 resets, and the pre-folded film 2-61 continues to be fed under the action of the film feeding mechanism 2-5. The position of the pre-folded film 2-61 corresponding to the medicine bag 40 (i.e., the cylindrical structure) moves to the bottom position corresponding to the horizontal sealing component. The next stroke of the sealing and cutting feed component 2-23 can horizontally seal the bottom of the position of the pre-folded film 2-61 corresponding to the medicine bag 40 (i.e., the cylindrical structure) and cut the pre-folded film 2-61 from below the horizontal sealing position to obtain an independent medicine bag 40 with a bag opening at the top. In this embodiment, the horizontal sealing area and the vertical sealing area of ​​the medicine bag 40 at least partially overlap, ultimately forming an L-shaped sealing edge.

[0050] In this embodiment, the bag-making device 2-0 below different bag-feeding stations is equipped with film rolls 2-6 of different properties. Specifically, the "film rolls 2-6 of different properties" means that the pre-folded film 2-61 on the film rolls configured by the bag-making device 2-0 below different bag-feeding stations has different colors, and / or, the pre-folded film 2-61 on the film rolls configured by the bag-making device 2-0 below different bag-feeding stations has indicator marks of different shapes and / or colors on the areas corresponding to each medicine bag 40. As a result, the medicine bags 40 produced by the bag-making device 2-0 below different bag-feeding stations have different colors, and / or the indicator marks on the medicine bags 40 produced by the bag-making device 2-0 below different bag-feeding stations have different shapes and / or colors.

[0051] Specifically, the indicator markings can be patterns printed on the pre-folded film 2-61.

[0052] Preferably, in this embodiment, the pre-folded film 2-61 on the roll film configured by the bag making device 2-0 below different bag-giving stations is of different colors, so as to achieve visual differentiation of the type of combined preparation contained in the medicine bag 40 through color.

[0053] In some possible embodiments, when a single patient requires the same components of a combination preparation at different medication times, this dispensing system can be used to simultaneously dispense prescriptions for multiple patients. Specifically, during the dispensing process, when the host computer receives and processes prescriptions, it determines the number of bag-making stations required based on the number of prescriptions. The host computer then controls the bag-making device 2-0 below the corresponding bag-making station to operate. During the dispensing process, the host computer uses patient identification information as the classification information for the medicine bags 40, classifying the medicine bags 40 produced by the bag-making device 2-0 below each bag-making station. When the medicine bag holding mechanism 4 moves to the dispensing station, the dispensing module 1 dispenses the medicine into the medicine bag 40 according to the classification information of the medicine bag 40, completing the dispensing of prescriptions for different patients. Medicine bags 40 of various colors are used to package combination preparations for different patients. After dispensing, sorting personnel can sort the medicine bags according to their color and distribute them to individual patients.

[0054] In other possible embodiments, the components of the combination formulation required by a single patient at different medication times may differ, and this dispensing system can be used to simultaneously dispense the combination formulation required by the patient at multiple different medication times.

[0055] Specifically, different formulations of combined preparations are used for the same patient to take at different times; the number of bag-giving stations is greater than or equal to the number of times of administration, and less than or equal to the number of types of combined preparations.

[0056] In some specific embodiments, a single patient has m medication periods, and the number of combination preparations to be taken in each medication period is n, where m and n are both positive integers. The number of medication periods m and the number of combination preparations to be taken in a single medication period n are both determined from the patient's prescription.

[0057] In some specific embodiments, if the same patient takes only one combination of medications during the same medication period, i.e., n=1, then the number of bag-giving stations M matches the number of medication periods m, i.e., M=m.

[0058] In some specific embodiments, if the same patient needs to take more than one combination of medications sequentially during the same medication period, i.e., n > 1, then the number of bag-giving stations M > m. Preferably, M = m•n, or M = m + n - 1.

[0059] Taking Mongolian medicine dispensing as an example, Mongolian medicine has a unique prescription feature of "three doses a day + medicinal guide." This means that the Mongolian medicine a patient needs to take daily must be prepared separately for three doses: morning, noon, and evening, and accompanied by a specific medicinal guide. Furthermore, the three doses and the medicinal guide must be packaged separately to ensure accurate administration. In other words, for Mongolian medicine dispensing, the prescription has three administration periods, m=3, and each administration period requires the sequential administration of the first and second combination preparations, n=2.

[0060] In some possible embodiments, the dispensing system for Mongolian medicine can be configured with six bag-giving stations, i.e., M=6. Below each of the six bag-giving stations is a bag-making device 2-0. The pre-folded film 2-61 of the film rolls 2-6 equipped with the six bag-making devices 2-0 are all different colors, resulting in different colored medicine bags 40. These six different colored medicine bags 40 are used to receive and package the first and second combination preparations for three different medication periods. After dispensing, sorting personnel and patients can distinguish between different medication periods and the two combination preparations within the same medication period by color, avoiding confusion and ensuring efficacy.

[0061] In this embodiment, a medicine bag receiving device 1-0 can be installed at the bag-dropping station 5-3. The medicine bag receiving device 1-0 includes multiple receiving containers 1-3. The host computer of the dispensing system classifies the medicine bags 40 according to the medication time period. The medicine bag receiving device 1-0 is configured to receive control signals from the host computer and, according to the classification information of the medicine bags 40, classify and receive the medicine bags 40 through multiple receiving containers 1-3. The number of receiving containers 1-3 is the same as the number of medication time periods, and the multiple receiving containers 1-3 are used to receive medicine bags 40 for different medication time periods. Thus, when the sorting personnel take out the medicine bags 40, they can add labels to the medicine bags 40. The labels are used to indicate at least the medication time period, making it easier for patients to distinguish them.

[0062] In some other preferred embodiments, the number M of the bag-giving stations is set to M = m + n - 1, which can avoid confusion due to too many colors of medicine bags 40, and can reduce the number of bag-making devices 2-0, thereby reducing the overall cost of the equipment.

[0063] Specifically, a medicine bag receiving device 1-0 is installed below the bag-dropping station 5-3. The medicine bag receiving device 1-0 includes multiple receiving containers 1-3. The medicine bag receiving device 1-0 is configured to receive control signals and, based on the classification information of the medicine bags 40, classify and receive the medicine bags 40 through the multiple receiving containers 1-3. The use of the medicine bag receiving device 1-0 to classify and receive the medicine bags 40 reduces the number of bag-making devices 2-0 while preventing the medicine bags 40 from becoming mixed up.

[0064] In this embodiment, the bag-giving station includes a first bag-giving station and a second bag-giving station. The first bag-giving station has multiple units, the same number as the number of medication administration periods. The bag-making devices 2-0 below the multiple first bag-giving stations are used to prepare various easily distinguishable first medicine bags. The various first medicine bags are used to receive the first combination preparations for different medication administration periods. The second bag-giving station has one unit and is used to prepare second medicine bags. The second medicine bags are used to receive the second combination preparations for different medication administration periods. The first medicine bags and second medicine bags corresponding to the same medication administration period are received by the same receiving container 1-3.

[0065] For the dispensing system used for Mongolian medicine, four bag-giving stations can be configured. Three of these stations are the first bag-giving stations, where the first medicine bags prepared by the bag-making device 2-0 below the first bag-giving stations are used to hold the first combination preparations for different medication periods. The last bag-giving station is the second bag-giving station, where the second medicine bags prepared by the bag-making device 2-0 below the second bag-giving station are used to hold the second combination preparations for different medication periods.

[0066] When the medicine bag holding mechanism 4 moves to the bag dropping station 5-3, the medicine bags 40 are sorted and received by the medicine bag receiving device 1-0. Specifically, the classification information is based on the medication time period. The first medicine bag of the first combination preparation and the second medicine bag of the second combination preparation for the same medication time period fall into the same receiving container 1-3, while the first medicine bags and second medicine bags of combination preparations for different medication time periods fall into different receiving containers 1-3. When taking the medicine, the patient can visually distinguish the medication time period and the type of combination preparation based on the color of the medicine bag 40. Specifically, if there are two colors of medicine bags 40 in the same receiving container 1-3, the color of the second medicine bag can be visually distinguished by whether its color is the same as the color of the medicine bags 40 in other receiving containers 1-3. The medication time period corresponding to this group of medicine bags 40 (the first medicine bag and the second medicine bag located in the same receiving container 1-3) can be visually distinguished by the color of the first medicine bag.

[0067] In this embodiment, the number of receiving containers 1-3 is the same as the number of medication administration periods, and multiple receiving containers 1-3 are used to receive medicine bags 40 for different medication administration periods.

[0068] In this embodiment, the components of the second combination preparation at different medication times may be the same or different. For Mongolian medicine dispensing, the first combination preparation is the main ingredient of the Mongolian medicine, and the second combination preparation is the guiding ingredient.

[0069] In some specific embodiments, the dispensing system further includes a label printing module located near the medicine bag dispensing outlet on the outer shell of the dispensing system; the label printed by the label printing module is used to indicate at least the medication administration period, and the label is fixed at least on the second medicine bag.

[0070] In some specific embodiments, when sorting personnel remove and package the medicine bags 40 from the medicine bag receiving device 1-0, they can print labels using a label printing module and affix these labels to the first and second medicine bags within each receiving container 1-3. This allows patients to further distinguish the medicine bags 40 based on the labels, creating a dual distinction with the colors and / or indicators on the medicine bags 40, thus preventing incorrect administration. For example, when dispensing Mongolian medicine, labels with phrases such as "take early" or "main medicine" can be affixed to the first medicine bag within a single receiving container 1-3, and labels with phrases such as "take early" or "guide medicine" can be affixed to the second medicine bag, facilitating patient differentiation.

[0071] In this embodiment, the control method of the dispensing system includes the following steps: S1: Host computer receives and processes data; S2: The medicine bag holding mechanism 4 moves to the bag feeding station, and multiple bag making devices 2-0 work to push the produced medicine bags 40 into the corresponding medicine bag holding mechanism 4 at the bag feeding station. S3: The host computer classifies the medicine bags 40 prepared by different bag-making devices 2-0; S4: The medicine bag holding mechanism 4 passes through multiple dispensing stations in sequence. The host computer controls the dispensing module 1 to output matching materials into the medicine bag 40 according to the prescription and the classification information of the medicine bag 40. S5: When the medicine bag holding mechanism 4 moves to the top sealing station 5-2, the host computer controls the top sealing device to seal the medicine bag 40. S6: When the medicine bag holding mechanism 4 moves to the bag dropping station 5-3, it sorts and accepts the medicine bag 40 according to the classification information of the medicine bag 40.

[0072] In the above scheme, within one working cycle of the adjustment system, multiple bag-making devices 2-0 can work sequentially, synchronously, or synchronously for some time periods, while only a few bag-making devices 2-0 work for some time periods.

[0073] In this embodiment, when a single patient needs to take the same components of a combination preparation at different medication times, prescriptions for multiple patients are dispensed simultaneously. The host computer uses patient identification information as the classification information for the medicine bags 40. In step S3, the medicine bags 40 prepared by the bag-making device 2-0 below the single bag-dispensing station are classified into one category for containing the combination preparation for a single patient. In step S4, when the medicine bag holding mechanism 4 moves to the dispensing station, the host computer outputs matching materials into the corresponding medicine bag 40 according to the prescription and patient identification information.

[0074] In this embodiment, when the components of the combination preparation required by a single patient are different at different medication times, the combination preparation required by the patient at multiple different medication times is adjusted simultaneously, and the host computer uses the medication time information as the classification information of the medicine bag 40 at least.

[0075] In this embodiment, when n equals 1, the medication time information can be used as the classification information for the medicine bag 40. When n is greater than 1, the preparation type information needs to be added as the classification information for the medicine bag 40 to ensure accurate dispensing in step S4. In step S6, the medicine bag 40 is classified and accepted using only the medication time information.

[0076] In this embodiment, in step S1, the host computer determines the number of bag-dispensing stations M to be worked based on the number m of medication periods in the prescription and the number n of the combined preparations for each medication period, where M = m + n - 1. When n is greater than 1, in step S3, the host computer uses the medication period information and preparation type information as the classification information for the medicine bags 40; in step S6, the host computer classifies and accepts the medicine bags 40 according to the medication period information.

[0077] Specifically, for the dispensing of Mongolian medicine, there are four bag-giving stations. In step S3, the host computer divides the medicine bags 40 produced by the bag-making device 2-0 below the four bag-giving stations into six categories: a first medicine bag for holding the main medicine for morning administration, a first medicine bag for holding the main medicine for mid-morning administration, a first medicine bag for holding the main medicine for evening administration, a second medicine bag for holding the medicine guide for morning administration, a second medicine bag for holding the medicine guide for mid-morning administration, and a second medicine bag for holding the medicine guide for evening administration. In step S4, as a medicine bag 40 moves through each dispensing station, the host computer controls the dispensing module 1 to output matching materials into the medicine bag 40 according to the prescription and the classification information of the medicine bag 40. The dispensing module 1 outputs several kinds of materials corresponding to the classification information of the medicine bag 40 on the prescription into the medicine bag 40 according to the weight on the prescription, thus completing the dispensing of the combination preparation corresponding to the classification information of the medicine bag 40 on the prescription.

[0078] Preferably, in this embodiment, at least when n>1, when the medicine bags 40 in the same receiving containers 1-3 are taken out, labels are affixed to the easily distinguishable medicine bags 40. The labels contain information on the time of administration and the order of administration. This facilitates differentiation for patients during the administration process.

[0079] In this embodiment, the host computer can be a PLC controller. The host computer is electrically connected to each electrical device through wires to realize fully automated control of the entire process.

[0080] like Figures 4 to 6As shown, in some specific embodiments, the medicine bag receiving device 1-0 includes a receiving device base 1-1, a receiving device body 1-2, and a receiving device drive assembly 1-4. The receiving device base 1-1 is horizontally fixed on the frame 2 of the dispensing system, or the receiving device base 1-1 is part of the frame 2, extending horizontally, and has sufficient structural strength to support the remaining components, providing a stable mounting foundation for the movement of the receiving device body 1-2.

[0081] The receiving device body 1-2 is mounted on the receiving device base 1-1 via the receiving device slide rail assembly 1-6. Multiple receiving containers 1-3 are mounted on the receiving device body 1-2, spaced apart along the length of the receiving device slide rail assembly 1-6. The receiving device drive assembly 1-4 is mounted on the receiving device base 1-1. The receiving device drive assembly 1-4 is configured to receive control signals and drive the receiving device body 1-2 to reciprocate along the receiving device slide rail assembly 1-6, thereby selectively switching one of the multiple receiving containers 1-3 to directly below the drug drop bag channel 1-9.

[0082] The receiving device slide rail assembly 1-6 includes two parallel receiving device linear guide rails 1-61 and receiving device sliders 1-62 respectively sleeved on the two receiving device linear guide rails 1-61 and slidably engaged with the two receiving device linear guide rails 1-61. The receiving device body 1-2 is fixedly connected to the receiving device sliders 1-62 of the receiving device slide rail assembly 1-6. Preferably, at least two receiving device sliders 1-62 are sleeved on each receiving device linear guide rail 1-61, and the receiving device body 1-2 is fixedly connected to each receiving device slider 1-62.

[0083] The receiving device body 1-2 includes a main support frame 1-21 and a container fixing bracket 1-22. The main support frame 1-21 is mounted on the receiving device base 1-1 via a receiving slide rail assembly. The driving end of the receiving device drive assembly 1-4 is connected to the main support frame 1-21. The container fixing bracket 1-22 is embedded in the main support frame 1-21. The container fixing bracket 1-22 is provided with multiple limiting grooves arranged at intervals along the length direction of the receiving device slide rail assembly 1-6. The receiving container 1-3 is detachably installed in the limiting grooves.

[0084] Preferably, the container fixing bracket 1-22 is retractably mounted on the main support frame 1-21. Along the pulling direction of the container fixing bracket 1-22, one end of the main support frame 1-21 is provided with a pull-out opening, and the other end is closed. The closed end of the main support frame 1-21 is used to limit the installation position of the container fixing bracket 1-22.

[0085] In this embodiment, a set of support slide rail assemblies 1-25 are respectively provided on the left and right sides of the container fixing bracket 1-22 along the pulling direction. A medicine bag dispensing port is provided on the dispensing system for the entire container fixing bracket 1-22 to be pulled out, and the container fixing bracket 1-22 is pulled out via the support slide rail assemblies 1-25. After all the receiving containers 1-3 on the receiving device body 1-2 have received the medicine bag 40 for the patient, that is, after the dispensing system has finished dispensing the medicine for the patient, the operator can pull out the entire container fixing bracket 1-22 and replace the receiving containers 1-3 on the container fixing bracket 1-22.

[0086] Preferably, the pulling direction of the container fixing bracket 1-22 is parallel to the length direction of the receiving device slide rail assembly 1-6.

[0087] Along the extension direction of the receiving slide rail assembly, a pull-out opening is located at one end of the main support frame 1-21. The container fixing bracket 1-22 is pulled out from the pull-out opening, extending parallel to the extension direction of the receiving slide rail assembly. The receiving container 1-3 moves along with the container fixing bracket 1-22 to outside the main support frame 1-21, avoiding the opening of the medicine bag dropping channel 1-9. The pull-out opening on the main support frame 1-21 is positioned opposite to the medicine bag dispensing outlet on the dispensing system for the entire container fixing bracket 1-22 to be pulled out.

[0088] Preferably, before the container fixing bracket 1-22 is pulled out, the receiving device drive assembly 1-4 operates, driving the receiving device body 1-2 to move, so that the pulling port is close to the medicine bag dispensing port on the dispensing system for the container fixing bracket 1-22 to be pulled out as a whole, making it convenient for the operator to pull out the container fixing bracket 1-22.

[0089] In this embodiment, a medicine bag handle 1-23 is provided at the end of the container fixing bracket 1-22 facing the pull-out opening.

[0090] During the movement of the receiving device body 1-2 driven by the receiving device drive assembly 1-4, a positioning assembly is provided between the container fixing bracket 1-22 and the main support frame 1-21 to ensure that no relative displacement occurs between them. The positioning assembly includes a magnetic attraction component disposed between the main support frame 1-21 and the container fixing bracket 1-22 and / or a snap-fit ​​structure disposed between the inner and outer slide rail components of the bracket slide rail assembly 1-25.

[0091] An installation position detection device 1-24 is installed between the main support frame 1-21 and the container fixing bracket 1-22. The installation position detection device 1-24 is electrically connected to the host computer of the dispensing system. The installation position detection device 1-24 can be a micro switch, which is triggered when the container fixing bracket 1-22 moves to the installation position. This ensures the accuracy of the assembly position and the accurate positioning between the receiving container 1-3 on the receiving device body 1-2 and the medicine bag channel 1-9 when the receiving device drive assembly 1-4 drives the receiving device body 1-2 to move.

[0092] A receiving position detection device is installed between the receiving device base 1-1 and the receiving device body 1-2. The receiving position detection device is electrically connected to the receiving device drive assembly 1-4 and is used to obtain the position of the receiving device body 1-2. The receiving position detection device includes multiple receiving position sensors installed on the receiving device base 1-1, the same number as the receiving containers 1-3, and a trigger unit installed on the receiving device body 1-2 that cooperates with the receiving position sensors. The multiple receiving position sensors are arranged at intervals along the length direction of the receiving device slide rail assembly 1-6 and are electrically connected to the receiving device drive assembly 1-4 respectively. When the receiving device body 1-2 moves to any receiving container 1-3 aligned with the drug drop bag channel 1-9, the trigger unit and the corresponding receiving position sensor are activated.

[0093] After the dispensing system completes the dispensing and sealing of the medicine bag 40 based on the prescription information, the host computer sends a control signal to the receiving device drive assembly 1-4 according to the classification information of the medicine bag 40. The receiving device drive assembly 1-4 receives the control signal and drives the receiving device body 1-2 to move along the receiving device slide rail assembly 1-6 until the trigger part on the receiving device body 1-2 engages with the receiving position sensor corresponding to the target receiving container 1-3 corresponding to the classification information of the medicine bag 40. At this time, the target receiving container 1-3 corresponding to the classification information moves to directly below the medicine bag dropping channel 1-9. The sealed medicine bag 40 in the medicine bag holding mechanism 4 falls through the medicine bag dropping channel 1-9.

[0094] In this embodiment, the receiving device drive components 1-4 can be either a lead screw motor control module or a synchronous belt component.

[0095] In some specific embodiments, the medicine bag holding mechanism 4 includes a fixed body and a movable body, which are spliced ​​together to form a space for accommodating the medicine bag. The space for accommodating the medicine bag extends vertically through the medicine bag holding mechanism 4. The fixed body is provided with a guide film groove for accommodating the side sealing edge of the medicine bag 40. A pressure block for fixing the medicine bag 40 in the medicine bag holding mechanism 4 is provided on the side of the fixed body away from the movable body. The pressure block is rotatably engaged with the fixed body, and a torsion spring is provided between the pressure block and the fixed body. The pressure block is located outside the guide film groove, and a clearance opening is provided on the groove wall of the guide film groove near the pressure block. The torsion spring is used to force the pressure block to rotate into the guide film groove, so that the pressure block extends at least partially into the guide film groove, pressing the side sealing edge of the medicine bag 40 against the groove wall of the guide film groove on the side away from the pressure block. Specifically, the pressure block includes a squeezing part extending towards the side of the guide film groove for squeezing the side sealing edge, and an abutting part extending away from the guide film groove.

[0096] In some specific embodiments, the bag-dropping station 5-3 is equipped with a bag-opening and bag-dropping mechanism 9. The bag-opening and bag-dropping mechanism is used to open the bag-pressing block, allowing the medicine bag 40 to detach from the medicine bag holding mechanism 4.

[0097] The bag dropping mechanism 9 is installed directly above the bag dropping station 5-3. It includes a bag dropping drive assembly 91 and a bag dropping rod 92 installed on the working end of the bag dropping drive assembly 91. The bag dropping mechanism 9 is used to knock the medicine bag 40 off after the bag pressing block releases its grip on the side seal of the medicine bag 40. The bag dropping rod 92 drive assembly can be a lead screw motor module or a synchronous belt assembly.

[0098] In some specific embodiments, the extension path of the transmission module 5 is a closed loop, which drives the medicine bag holding mechanism 4 to move cyclically between the bag feeding station, the dispensing station, the top sealing station 5-2 and the bag dropping station 5-3.

[0099] The first side of the medicine bag holding mechanism 4 is connected to the transmission module 5, and the second side of the medicine bag holding mechanism 4 is provided with a support wheel 41. The axis of rotation of the support wheel 41 is perpendicular to the extension path of the transmission module 5. A support rail 50 is also provided on the frame 2. The support rail 50 is located on the side of the transmission module 5 where the medicine bag holding mechanism 4 is installed. The extension path of the support rail 50 is parallel to the extension path of the transmission module 5 and is used to support the support wheel 41. Thus, the first side of the medicine bag holding mechanism 4 is fixed to the transmission module 5, and the second side of the medicine bag holding mechanism 4 is supported on the support rail 50 by the support wheel 41, which improves the support effect of the medicine bag holding mechanism 4. Specifically, the axis of the transmission module 5 is vertical, which can prevent the synchronous belt or chain 51 of the transmission module 5 from deforming due to the weight of the medicine bag holding mechanism 4, and prevent the medicine bag holding mechanism 4 from tilting downward on its second side under the action of gravity, so that the medicine bag holding mechanism 4 always remains in a horizontal state during transmission.

[0100] At least at the bag feeding station and the bag dropping station 5-3, the support rail 50 and the transmission module 5 are spaced apart. The interval between the transmission module 5 and the support rail 50 corresponds to the space of the medicine bag holding mechanism 4 for accommodating the medicine bag, so as to allow the medicine bag 40 to enter the medicine bag holding mechanism 4 and to detach from the medicine bag holding mechanism 4.

[0101] In this embodiment, the fixed body is fixedly connected to the transmission module 5, the movable body is foldably mounted on the fixed body, and the support wheel 41 is mounted on the fixed body. Preferably, the fixed body and the movable body are arranged opposite each other along a direction parallel to the extension path of the transmission module 5; when the medicine bag holding mechanism 4 is opened, the movable body moves by translating to the side away from the fixed body.

[0102] In some specific embodiments, the transmission module 5 includes a chain 51, a chain drive assembly 52, and a driven wheel 53. The chain 51 is connected end to end to form a closed loop structure. The chain drive assembly 52 is used to drive the chain 51 to move cyclically along the closed loop structure. The medicine bag holding mechanism 4 is detachably mounted on the chain 51. The support track 50 is circular and is set on the outside of the transmission module 5, surrounding the transmission module 5. The chain drive assembly 52 includes a chain drive gear 521 that meshes with the chain 51 and a chain drive motor that is connected to the chain drive gear 521 and used to drive the chain drive gear 521 to rotate. By driving the chain drive gear 521 to rotate through the chain drive motor, the chain 51 can be moved, ensuring transmission accuracy.

[0103] In this embodiment, multiple medicine bag holding mechanisms 4 are evenly arranged along the extension path of the transmission module 5; the distance between two adjacent bag-feeding stations is the same as the distance between two adjacent medicine bag holding mechanisms 4. Therefore, at each bag-feeding station, when there is an empty medicine bag holding mechanism 4 above each working bag-feeding station, the bag-making devices 2-0 below the multiple bag-feeding stations can work synchronously or sequentially. When the demand for different types of medicine bags 40 varies, the bag-making device 2-0 below a certain bag-feeding station can also be controlled to work independently.

[0104] In this embodiment, when the medicine bag holding mechanism 4 moves to the bag making station, if multiple bag making devices need to work simultaneously, the host computer control and transmission module continues to operate after all multiple bag making devices have completed their bag making work. Similarly, when the medicine bag holding mechanism moves to the dispensing station, if multiple dispensing cabinets above the dispensing stations need to work simultaneously, the host computer control and transmission module continues to operate after all multiple dispensing cabinets have completed their dispensing work.

[0105] The transmission module 5 includes multiple long, straight transmission sections. Multiple dispensing stations are evenly arranged along at least a portion of these transmission sections. The distance between two adjacent dispensing stations on the same transmission section is the same as the distance between two adjacent medicine bag holding mechanisms 4. Specifically, the spacing between two adjacent medicine bag holding mechanisms 4 is the same. Driven by the transmission module 5, the medicine bag holding mechanism 4 passes through each dispensing station sequentially and pauses at each station. When the dispensing cabinet 10 above the dispensing station where a medicine bag holding mechanism 4 is paused contains the materials required for that medicine bag 40, the corresponding dispensing cabinet 10 operates, dispensing a fixed quantity of materials into the medicine bag 40 according to the prescription.

[0106] In this embodiment, two or more sets of photoelectric sensors can be configured on the frame 2 to collect the position information of the medicine bag holding mechanism 4 in real time, so as to ensure that the medicine bag holding mechanism 4 can be accurately positioned at the bag feeding station, the dispensing station, the top sealing station 5-2 and the bag dropping work.

[0107] like Figure 2 As shown, in some preferred embodiments, the extension path of the transmission module 5 includes a first transmission segment 511 extending along a first direction, a second transmission segment 512 disposed at both ends of the first transmission segment 511 and perpendicular to the first transmission segment 511, and a third transmission segment 513 disposed opposite to the first transmission segment 511. The middle portion of the third transmission segment 513 protrudes towards the first transmission segment 511, and the protruding portion of the third transmission segment 513 includes a first transmission segment 5131 parallel to the first transmission segment 511 and a second transmission segment 5132 parallel to the second transmission segment 512. The third transmission segment 513 also includes two third transmission segments 5133, and the second transmission segments 5132 and the second transmission segment 512 are connected by the third transmission segments 5133. Thus, the extension path of the transmission module 5 forms a U-shaped structure.

[0108] The transmission module 5 is also equipped with chain tensioning components. There are two chain tensioning components, each corresponding to the middle of one of the two third transmission segments 5133. The adjustment cabinet 10 is positioned above the first transmission segment 511, the second transmission segment 512, the first transmission segment 5131, and the second transmission segment 5132, but not above the third transmission segment 5133.

[0109] In this embodiment, the dispensing module 1 includes multiple dispensing cabinets 10 for quantitatively dispensing different types of materials. Preferably, at least two dispensing cabinets 10 are grouped close to each other, each group of dispensing cabinets 10 corresponds to a converging pipe 3, and a dispensing station is formed below each converging pipe 3. This reduces the number of dispensing stations and helps to reduce the overall layout area of ​​the dispensing system.

[0110] In some specific embodiments, the dispensing cabinet 10 can be a powder dispensing cabinet, which is inclined from top to bottom, with the outlets 12 of the same group of powder dispensing cabinets close to each other. The close proximity of the outlets 12 of the same group of powder dispensing cabinets makes the converging pipe 33 short and compact, which greatly reduces the amount of powder residue, making the equipment adaptable to the multi-powder metering requirements of Mongolian medicine and traditional Chinese medicine compound preparations, and ensuring accurate and controllable powder dosage.

[0111] like Figure 1 and Figure 7 As shown, in this embodiment, powder dispensing cabinets are arranged in pairs in the horizontal direction perpendicular to the transmission module 5. The powder dispensing cabinets are mounted and fitted onto the frame 2, and the outlets 12 of the paired powder dispensing cabinets are close to each other. Specifically, two powder dispensing cabinets are grouped together, and a converging pipe 3 is provided on the frame 2 corresponding to each group of powder dispensing cabinets. Each converging pipe 3 only needs to match the outlet 12 of one group of powder dispensing cabinets to achieve full reception. The powder dispensing cabinets are arranged at an angle from top to bottom, with the outlets 12 of the same group of powder dispensing cabinets close to each other. Therefore, it is no longer necessary to expand the horizontal dimension of the upper inlet of the converging pipe 3 to cover the dispersed outlets, directly reducing the contact area between the powder and the side wall of the converging pipe 3 and the friction time during the fall, reducing the amount of residue adhering to the side wall of the converging pipe 3, reducing raw material waste, and improving powder metering accuracy.

[0112] In this embodiment, the powder dispensing cabinet is inclined from top to bottom towards the converging pipe 3. A partition is provided inside the converging pipe 3 to divide the converging pipe 3 into two sub-channels. The two sub-channels are used to transport the powder output from the two powder dispensing cabinets in the same group.

[0113] Two powder dispensing cabinets in the same group are symmetrically arranged with respect to the axis of the converging pipe 3. The axis of the converging pipe 3 extends vertically. Preferably, the angle between the axis of the powder dispensing cabinet and the axis of the converging pipe 3 is greater than 0° and less than or equal to 30°, thereby ensuring the stability of the powder dispensing cabinet's dispensing. More preferably, the angle between the axis of the powder dispensing cabinet and the axis of the converging pipe 3 is 25°.

[0114] Preferably, the powder dispensing cabinet is mounted and coordinated with the rack 2.

[0115] The frame 2 includes a single-cabinet support profile 21, and a single-cabinet support device 22 is mounted on the single-cabinet support profile 21. The single-cabinet support device 22 includes a pair of opposing single-cabinet support plates 221, a hanging arm 222, and a stop 223. The pair of single-cabinet support plates 221 are respectively provided with a first hanging arm and a second hanging arm extending outwards. Two single-cabinet hooks 16 are provided on the powder dispensing cabinet, and the two single-cabinet hooks 16 are respectively hooked onto the first hanging arm and the second hanging arm. The stop 223 is located below the hanging arm 222 and is used to support the powder dispensing cabinet.

[0116] The bottom of the single cabinet support plate 221 is provided with a support plate base 2211 that bends and extends horizontally. The support plate base 2211 at the bottom of the single cabinet support plate 221 is attached to the top of the single cabinet support profile 21 and is fixedly connected by bolts. Two powder dispensing single cabinets in the same group are hung on the hanging arms 222 of the single cabinet support plate 221 from the left and right sides of the single cabinet support profile 21.

[0117] When installing the powder dispensing cabinet, simply hang the cabinet hook 16 on the mounting arm 222. Since the cabinet hook 16 is located on the side of the powder dispensing cabinet, the powder dispensing cabinet rotates relative to the cabinet support plate 221 under its own weight. The side wall of the powder dispensing cabinet located below the cabinet hook 16 abuts against the stop part 223 on the cabinet support plate 221, thereby stably hanging the powder dispensing cabinet on the frame 2.

[0118] In this embodiment, a set of first hanging arms and second hanging arms for mounting a powder dispensing cabinet are coaxially arranged, and the axes of the set of first hanging arms and second hanging arms constitute the rotation axis of the powder dispensing cabinet during mounting.

[0119] The feeding pipe 113 of the single cabinet hook 16 and the hopper 11 is located on the same side of the powder dispensing cabinet. A space is formed between the two opposing single cabinet support plates 221 to accommodate the feeding pipe 113 of the powder dispensing cabinet. The feeding pipe 113 is located between the two single cabinet support plates 221.

[0120] In this embodiment, at least at the bag feeding station and bag dropping station 5-3 of the dispensing system, a bag opening mechanism is provided for squeezing the abutment part to make the bag pressing block rotate outward of the guide film groove and release the squeezing.

[0121] The bag-opening and clamping mechanism at the bag-feeding station is used to squeeze the bag-pressing block of the bag-holding mechanism 4 before the medicine bag 40 enters the bag-holding mechanism 4, so that the medicine bag 40 can smoothly enter the bag-holding mechanism 4. After the medicine bag 40 enters the bag-holding mechanism 4, the squeezing of the bag-pressing block is released, so that the bag-pressing block presses the side seal of the medicine bag 40, fixing the medicine bag 40 in the bag-holding mechanism 4.

[0122] The bag-opening mechanism at the bag-dropping station 5-3 is used to release the clamping block from the medicine bag 40, allowing the medicine bag 40 to detach from the medicine bag holding mechanism 4.

[0123] In this embodiment, a rejection station is provided between the bag-feeding station and the dispensing station. The rejection station is equipped with a bag-opening mechanism to relieve the pressure of the bag-holding block on the medicine bag, a bag-opening support mechanism to open the medicine bag holding mechanism, and a bag-dropping mechanism 9 to knock the medicine bag 40 off. A bag-opening detection module for identifying whether the opening of the medicine bag 40 is fully open is located above the bag-feeding station and / or above the rejection station. Preferably, the bag-opening detection module is located above the rejection station. The bag-opening detection module includes a camera device for identifying whether the opening of the medicine bag 40 is fully open. The camera device is electrically connected to the host computer. The working end of the camera device is set towards the rejection station. When the medicine bag holding mechanism 4 moves to the rejection station, the camera device recognizes the image of the medicine bag 40, and the host computer of the dispensing system determines whether the opening of the medicine bag 40 is fully open based on the image. If the opening of the medicine bag 40 is not fully opened, the bag-opening clamping mechanism squeezes the bag-pressing block, causing it to rotate outwards towards the guide film groove, releasing the clamping of the side seal of the medicine bag. The bag-opening support mechanism then drives the movable body to move away from the fixed body, keeping the medicine bag holding mechanism open. Finally, the bag-dropping mechanism 9 operates, knocking the medicine bag 40 off. When this bag support moves to the dispensing station, the dispensing cabinet 10 corresponding to it does not operate.

[0124] In this embodiment, the dispensing cabinet 10 can be increased or decreased according to the personalized needs of the prescription. Preferably, based on research, for Mongolian medicine dispensing, the dispensing system is preferably equipped with 100 powder dispensing cabinets.

[0125] In some specific embodiments, the dispensing system is equipped with a photoelectric position detection component. This component detects the position of the medicine bag holding mechanism 4, causing it to stop at the bag-dropping station to complete the bag dropping. In some specific embodiments, the photoelectric position detection component includes a photoelectric position sensor mounted on the frame and a baffle mounted on the medicine bag holding mechanism. The photoelectric position sensor is communicatively connected to a transmission module. When the baffle aligns with the photoelectric position sensor, the transmission module pauses operation. At this time, one medicine bag holding mechanism stops at the bag-dropping station, and medicine bag holding mechanisms are respectively positioned at the dispensing station, bag-feeding station, and top-sealing station. Preferably, at least two sets of photoelectric position detection components are provided to ensure detection accuracy.

[0126] Preferably, the dispensing system is also equipped with a transmission verification module, which includes a barcode reader installed on the rack of the dispensing system. Each medicine bag holding mechanism 4 is equipped with an identification code. When the medicine bag holding mechanism 4 moves to the bag dropping station, the identification code corresponds to the barcode reader. The transmission verification module is electrically connected to the host computer of the dispensing system.

[0127] In this embodiment, the barcode reader is located at the bag-dropping station, or upstream of the bag-dropping station. The identification code can be a barcode or a QR code, and the type of the barcode reader matches the type of the identification code. The barcode reader can obtain information about the medicine bag holding mechanism 4 by scanning the identification code, and the information about the medicine bag holding mechanism 4 includes at least its code.

[0128] When the dispensing system malfunctions, such as when the photoelectric position detection component malfunctions or is damaged, the system shuts down and issues an alarm signal. After the operator adjusts the system, it restarts. The host computer uses the identification information from the verification module to determine if the coding of the medicine bag holding mechanism 4 at each station is correct. Specifically, the host computer can use the identification information from the verification module to determine if the coding of the medicine bag holding mechanism 4 at the bag dropping station is correct. If the coding is correct, the dispensing system continues to operate. If the coding is incorrect, the control transmission module is reset, causing the medicine bag holding mechanism with the correct coding to move to the bag dropping station to prevent medicine bags from being missed.

[0129] In this embodiment, the intervals between each medicine bag holding mechanism 4 are the same, and the codes of each medicine bag holding mechanism 4 are set sequentially. When the code reader is set upstream of the bag dropping station, the host computer can determine the code of the medicine bag holding mechanism at the bag dropping station based on the currently acquired code.

[0130] In this embodiment, during the operation of the dispensing system, each medicine bag holding mechanism stops sequentially at the bag dropping station. Each time the transmission module stops, medicine bag holding mechanisms remain at each bag feeding station, rejection station, dispensing station, and top sealing station. After the transmission module drives the medicine bag holding mechanisms to reset, the medicine bag holding mechanisms at each bag feeding station, rejection station, dispensing station, and top sealing station simultaneously reset. At this time, the host computer can control the dispensing module, top sealing device, bag making device, bag opening mechanism, bag opening support mechanism, and bag dropping mechanism to continue operating. This prevents medicine bag holding mechanisms without medicine bags from moving to the rejection station; prevents medicine bags with incomplete openings from moving to the bag feeding station; prevents medicine bags from missing or repeatedly receiving material during dispensing, ensuring dispensing accuracy; and prevents unsealed medicine bags from moving to the bag dropping station, thus ensuring the smooth progress of subsequent dispensing processes.

[0131] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention. The implementation schemes in the above embodiments can be further combined or replaced. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
