Description

Technical Field

[0001] This invention relates to the field of pharmaceutical packaging technology, and in particular to a drug receiving and packaging device and control method. Background Technology

[0002] Pharmaceutical packaging equipment primarily functions to dispense, seal, label, and verify medications according to doctor's orders or regulations. This ensures safe, accurate, efficient, and compliant dispensing while improving dispensing efficiency and reducing labor costs. Existing pharmaceutical packaging equipment typically dispenses the patient's prescribed medication into a receiving tray, simultaneously printing the label and placing it in the tray. The tray containing the medication and label is then conveyed out for pharmacy staff to retrieve and deliver to the inpatient department or patient. However, this method of receiving and dispensing medication in trays requires daily or periodic cleaning and disinfection due to contact with the medication, which is time-consuming, labor-intensive, and increases labor costs. Summary of the Invention

[0003] The present invention aims to solve the technical problems existing in the prior art and provide a medicine receiving and packaging equipment and control method, which can avoid cleaning and disinfecting the medicine receiving frame, save time and effort, and save labor costs.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solutions:

[0005] The present invention provides a drug receiving and packaging device, comprising a drug conveying structure, a drug packaging and labeling mechanism, and a drug output structure;

[0006] The drug conveying structure is connected between the drug storage cabinet and the drug packaging and labeling mechanism, and is used to receive drugs from the drug storage cabinet and convey the drugs to the drug packaging and labeling mechanism; the drug packaging and labeling mechanism is also connected to the drug output structure, and the drug packaging and labeling mechanism packages and seals the received drugs and then conveys them to the drug output structure;

[0007] The drug packaging and labeling mechanism includes a packaging and sealing structure, which includes a bag roll assembly, a blower assembly, a feeding support assembly, and a sealing assembly. The bag roll assembly conveys the packaging bag wound on it to the blower assembly, which blows air towards the packaging bag to open the bag opening. A portion of the feeding support assembly extends into the packaging bag from the bag opening and expands the packaging bag. The sealing assembly heat-seals and separates the packaging bag, and the separated packaging bags fall onto the drug output structure. The feeding support assembly includes a feeding hopper, and the drug conveying structure includes a spiral chute. The outlet end of the spiral chute is opposite to or extends into the feeding inlet of the feeding hopper.

[0008] Furthermore, the drug packaging and labeling mechanism includes a mounting housing, and the bag roll assembly includes a packaging bag winding roller disposed outside the mounting housing and a transmission roller assembly disposed inside the mounting housing. The packaging bag is wound around the packaging bag winding roller, and the starting end of the packaging bag is wound along the transmission roller assembly and extends below the blower assembly and the feed support assembly.

[0009] Furthermore, the drug packaging and labeling mechanism includes a mounting housing, and the blower assembly is disposed inside the mounting housing. The blower assembly includes an air pump and an air outlet. The air outlet is connected to the air outlet of the air pump through a pipeline, and the air outlet is located above the opening of the packaging bag.

[0010] Furthermore, the drug packaging and labeling mechanism includes a mounting shell, and the feeding support assembly further includes a bag support assembly. One end of the feeding hopper's inlet is located outside the mounting shell, and one end of the feeding hopper's outlet extends into the interior of the mounting shell, and the outlet end is connected to the bag support assembly. The bag support assembly includes a first rotating member and a second rotating member. The first rotating member and the second rotating member are rotatably connected to the side wall of the outlet end of the feeding hopper, and the first rotating member and the second rotating member are symmetrically arranged. When the first rotating member and the second rotating member are not under force, the free end of the first rotating member contacts the free end of the second rotating member to close the outlet of the feeding hopper.

[0011] Furthermore, the feed support assembly also includes a lifting structure, which is mounted on a support seat connected inside the mounting housing and causes the feed hopper and the support assembly to rise and fall.

[0012] Furthermore, when the free ends of the first rotating member and the second rotating member come into contact, the sidewalls of the first rotating member and the sidewalls of the second rotating member abut to form a triangle.

[0013] Furthermore, the drug packaging and labeling mechanism includes an installation housing, and the sealing assembly includes a sealing machine and a support shaft. The sealing machine is disposed inside the installation housing and includes a fixed sealing plate and a movable sealing plate. The two ends of the fixed sealing plate are connected to corresponding side walls of the installation housing. The support shaft is spaced apart from the fixed sealing plate along its length. The two ends of the movable sealing plate are slidably fitted onto the support shaft at corresponding ends. The movable sealing plate and the fixed sealing plate are respectively provided with… A heating element is placed on the movable sealing plate and the fixed sealing plate, which are arranged opposite to each other. Alternatively, a heating element can be placed on one of the movable sealing plate and the fixed sealing plate, and a sealing element arranged opposite to the heating element can be placed on the other. Before the fixed sealing plate and the movable sealing plate are closed, the starting end of the packaging bag extends between the fixed sealing plate and the movable sealing plate, and the opening of the packaging bag to be sealed is located between the two heating elements, or between the heating element and the sealing element.

[0014] Furthermore, the drug packaging and labeling mechanism includes a mounting housing, and the bag roll assembly includes a transmission roller assembly disposed inside the mounting housing; the transmission roller assembly includes a first transmission roller group, a second transmission roller group, a third transmission roller group, and a fourth transmission roller group, with the second transmission roller group located below the first and third transmission roller groups, so that the first, second, and third transmission roller groups are arranged to form a groove; the fourth transmission roller group is disposed behind the third transmission roller group, and the packaging bag is stretched flat between the third and fourth transmission roller groups; the drug packaging and labeling mechanism also includes a label printing and affixing assembly disposed inside the mounting housing, the label printing and affixing assembly including a label printer and a label affixing assembly, the label printer being located in the area corresponding to the groove, and the label affixing assembly including a suction cup seat movable relative to the label printer, with a suction cup disposed on the suction cup seat, the suction cup seat driving the suction cup to move to the label printer to pick up the label, and then moving between the third and fourth transmission roller groups to affix the label to the packaging bag.

[0015] The control method for a drug packaging device according to the present invention includes the following steps:

[0016] S1. Receive medical order information from the hospital's medication dispensing system and obtain drug list information based on the medical order information;

[0017] S2. The obtained drug list information is sent to the drug packaging and labeling organization. The drug packaging and labeling organization prints labels according to the received drug list information and affixes the labels to the packaging bags. Then, the labeled packaging bags are transported to the bottom of the drug conveying structure, and the opening of the packaging bags is opened to prepare for packaging.

[0018] S3. Control the drug storage cabinet to dispense drugs onto the drug conveying structure based on the obtained drug list information, and then transport the drugs to the packaging bag below its outlet via the drug conveying structure.

[0019] S4. The drug packaging and labeling mechanism seals and separates the packaging bags containing drugs, allowing the packaging bags containing drugs to fall onto the drug output structure and be conveyed out of the drug receiving and packaging equipment.

[0020] Furthermore, in step S1, the number and size of the medicine boxes are analyzed based on the medical order information and compared with the drug database to determine whether all medicines in the drug list information need to be split and packaged, and to determine the number of packages after splitting. The determination result is then fed back to the hospital's dispensing system. If splitting and packaging are not required, the process proceeds to step S2 after obtaining the drug list information based on the medical order information. If splitting and packaging are required, the hospital's dispensing system matches the corresponding medical order information according to the number of packages to be split and packages, and sends the medical order information to the receiving and packaging equipment in sequence and at a predetermined time.

[0021] The drug receiving and packaging equipment and control method described in this invention package and seals the drugs through the packaging and sealing structure in the drug packaging and labeling mechanism, thereby eliminating the need for a drug receiving frame and the need for cleaning and disinfecting the drug receiving frame, which greatly saves labor costs and saves time and effort.

Detailed Implementation

[0028] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be given below with reference to the accompanying drawings.

[0029] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to and integrated with the other component, or there may be an intervening component present. The terms "mounted," "one end," "the other end," and similar expressions used in this document are for illustrative purposes only.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0031] This invention specifically provides an embodiment of a drug packaging device, see [link to embodiment]. Figure 1The system includes a drug conveying structure, a drug packaging and labeling mechanism, and a drug output structure. The drug conveying structure is connected between the drug storage cabinet 1 and the drug packaging and labeling mechanism. It receives drugs from the drug storage cabinet 1 and conveys the received drugs to the drug packaging and labeling mechanism. In this embodiment, the drug storage cabinet 1 is existing technology. The hospital's dispensing system generates prescription information based on the doctor's orders and controls the drug storage cabinet 1 to transport the drugs that need to be dispensed to the drug conveying structure. In this embodiment, the drug conveying structure includes a horizontally arranged drug conveyor belt 2, which is installed inside the first housing 3. The drug conveyor belt 2 uses belt conveying. The drug conveying structure also includes a spiral slide 4, which is arranged along the height direction. One end of the spiral slide 4 is connected to the outlet of the first housing 3, and the other end (i.e., the outlet end) is connected to the inlet of the feed hopper 5. Yes, it can also be directly inserted into the feed inlet of the feed hopper 5 to ensure that the medicine can accurately enter the feed hopper 5 after sliding down the spiral slide 4. Using the spiral slide 4 to transport medicines can keep a certain distance between adjacent medicines during the transport process. By setting up cameras and other devices on the spiral slide 4, individual medicines can be recorded and fed back to the hospital's dispensing system to verify whether the dispensing information is consistent with the doctor's order information, ensuring the safety of dispensing. Multiple connecting rods 6 are set at intervals at the bottom of the first outer shell 3. The first outer shell 3 is connected to the medicine storage cabinet 1 through the connecting rods 6, and the first outer shell 3 and the medicine storage cabinet 1 are arranged at intervals. An inclined dispensing channel 7 is also set on the outer wall of the first outer shell 3. One end of the dispensing channel 7 is connected to the inside of the medicine storage cabinet 1, which is conducive to the medicine sliding down from the dispensing channel 7 into the medicine conveyor belt 2 inside the first outer shell 3.

[0032] In this embodiment, see Figure 1The drug packaging and labeling mechanism is also connected to the drug output structure. The drug packaging and labeling mechanism packages and seals the received drugs and then conveys them to the drug output structure. Specifically, the inlet of the feed hopper 5 in the drug packaging and labeling mechanism is connected to the outlet of the spiral chute 4 in the drug conveying structure. This connection can be direct or the outlet of the spiral chute 4 can extend into the inlet of the feed hopper 5. The drug output structure includes a first mounting bracket 8, on which a conveyor belt is mounted for receiving drug packages and conveying the packaged drug packages out. A portion of the first mounting bracket 8 is horizontal, and another portion is inclined. The horizontal portion is located inside the mounting housing 9 and below the outlet of the feed hopper 5, while the inclined portion is located outside the mounting housing 9. The inclined portion has a first end and a second end. The structure has two ends, one end of which is connected to one end of a horizontal section, and the other end of which is higher than the first end, forming an incline from low to high from the first end to the second end. This structure can not only receive packaged medicines but also allow the packaged medicines to rise from a low position to a high position so that they can fall into the receiving frame 11 on the dispensing conveyor belt 10 at the end of the medicine dispensing structure. By setting the receiving frame 11 on the dispensing conveyor belt 10, packaged medicines for the same patient can be placed in the same receiving frame 11, packaged medicines needed by the inpatient department can be placed in the same receiving frame 11, or packaged medicines within a certain time period can be placed in the same receiving frame 11 for delivery to staff. This significantly reduces the number of receiving frames 11 and also avoids direct contact between the medicines and the receiving frames 11, thus preventing contamination.

[0033] In this embodiment, see Figure 2The pharmaceutical packaging and labeling mechanism includes a packaging and sealing structure, which comprises a bag roll assembly, a blower assembly, a feeding support assembly, and a sealing assembly. The bag roll assembly conveys the packaging bag 12 wound around it to the blower assembly, specifically to the area below the blower assembly, so that the pre-opening of the packaging bag 12 is directly opposite the air outlet 13. The pre-opening of the packaging bag refers to the pre-layering or partial tearing of one side of the bag opening during packaging bag production, which facilitates the subsequent blowing of air to open the bag opening. However, the production process of pre-opening the packaging bag is existing technology and is not the inventive point of this application. The blower assembly blows air towards the pre-opening of the packaging bag 12 to cause the bag opening of the packaging bag 12 to open. That is, with the cooperation of the bag roll assembly, the packaging bag 12 is taut. When the bag opening is below the air outlet 13 of the blower assembly, the air blows towards the bag opening through the blower assembly. The blower nozzle opens the bag opening, preparing for the subsequent feeding and opening assembly to extend into the packaging bag 12 and open it. In this embodiment, the nozzle 13 is 2cm to 10cm away from the bag opening, such as 2cm, 3cm, 4cm, 5cm, 6cm, 7cm, 8cm, 9cm, or 10cm, which can more effectively blow open the bag opening. A part of the feeding and opening assembly extends into the packaging bag 12 from the bag opening and opens the packaging bag 12. The sealing assembly heat-seals and divides the packaging bag 12. The divided packaging bag 12 falls onto the drug output structure, specifically onto the horizontal part of the drug output structure. The feeding and opening assembly includes a feeding hopper 5, and the drug conveying structure includes a spiral slide 4. The outlet end of the spiral slide 4 is opposite to or extends into the feeding inlet of the feeding hopper 5.

[0034] In the preferred embodiment, see Figure 3The pharmaceutical packaging and labeling mechanism includes a mounting housing 9, and a bag roll assembly including a bag winding roller 14 disposed outside the mounting housing 9 and a drive roller assembly disposed inside the mounting housing 9. The packaging bag 12 is wound around the bag winding roller 14, with the starting end of the packaging bag 12 winding along the drive roller assembly and extending below the feed support assembly. Through the cooperation of the bag winding roller 14 and the drive roller assembly, continuous feeding of the packaging bag 12 can be achieved, while ensuring that the packaging bag 12 is always in a taut state, facilitating transmission and subsequent bag opening and support operations. Specifically, a pair of support members 15 are spaced apart on the outer wall of the mounting housing 9. The packaging bag winding roller 14 can be rotatably connected between the two support members 15 or fixedly connected between the two support members 15. When the packaging bag winding roller 14 is fixedly connected between the two support members 15, the core of the packaging bag 12 (the core support member 15 used to wind the packaging bag 12) can only be fitted onto the packaging bag winding roller 14 with a clearance fit, so as to facilitate the packaging bag 12 being pulled by the transmission roller assembly. An opening is provided on the side wall of the mounting housing 9 so that the starting end of the packaging bag 12 can pass through and enter the interior of the mounting housing 9. Rollers 16 are provided on the bottom surface of the mounting housing 9 to facilitate movement. The system includes a housing 9 and components installed inside it; a brake is provided on the roller 16, which locks the roller 16 after the housing 9 is moved into place, preventing the housing 9 from sliding arbitrarily; the transmission roller assembly includes a first transmission roller group 17, a second transmission roller group 18, a third transmission roller group 19, and a fourth transmission roller group 20. The second transmission roller group 18 is located below the first transmission roller group 17 and the third transmission roller group 19, so that the first transmission roller group 17, the second transmission roller group 18, and the third transmission roller group 19 are arranged to form a groove; the fourth transmission roller group 20 is located behind the third transmission roller group 19, and the packaging bag 12 is stretched flat between the third transmission roller group 19 and the fourth transmission roller group 20;The pharmaceutical packaging and labeling mechanism also includes a label printing and affixing component housed inside the mounting housing 9. This component comprises a label printer and a label affixing assembly. The label printer is located within the corresponding recessed area; specifically, the label paper roll assembly of the label printer is located within this recess, while the label printer body 21 is positioned above the label paper roll assembly. The starting end of the packaging bag 12 is sequentially wound around the first drive roller group 17, the second drive roller group 18, and the third drive roller group 19, forming a taut state. This not only ensures the packaging bag 12 remains taut but also allows the label printer to be installed within the confined space of the mounting housing 9, fully utilizing the internal space of the mounting housing 9. This embodiment... The label printer in this example is existing technology. It is connected to the inner wall of the mounting housing 9 via a mounting bracket. The printing exit 22 of the label printer body 21 is higher than the first drive roller group 17 and the third drive roller group 19 to facilitate the label application component in picking up the printed label paper 23. The label paper roll assembly includes an unwinding component and a rewinding component. The unwinding component releases the backing paper roll with the label paper, and the rewinding component retrieves the backing paper roll after the label paper has been peeled off. After the label paper exits from the printing exit 22 of the label printer body 21, it is attracted by the negative pressure of the suction cup, causing the label to peel off from the backing paper for subsequent labeling on packaging bags. The drive roller assembly also includes a fifth drive roller group 24. The fifth drive roller group 24... The assembly includes two vertically arranged drive rollers with a gap between them for the packaging bag 12 to pass through. A fifth drive roller group 24 drives the packaging bag 12. A tension roller 25 is positioned between the fifth drive roller group 24 and the first drive roller group 17, keeping the packaging bag 12 taut and facilitating its transport. A fourth drive roller group 20 is positioned behind the third drive roller group 19, and the packaging bag 12 is stretched taut between the third and fourth drive roller groups 19, facilitating the label application component's application of labels to the surface of the packaging bag 12. The drive roller assembly also includes a fixing and pressing assembly 26, which also includes two vertically arranged drive rollers with a gap between them. The gap through which the packaging bag 12 passes is facilitated by the cooperation of the fifth transmission roller group 24 and the fixed pressing assembly 26, enabling smooth conveying of the packaging bag 12. Behind the fixed pressing assembly 26, a support roller group 27 is also provided. The support roller group 27 includes two horizontally spaced transmission rollers that provide support for the taut packaging bag 12. Through the cooperation of the fixed pressing assembly 26 and the support roller group 27, and the positional relationship between the air outlet 13 and the support roller group 27, while ensuring a simple structure, the airflow can effectively prevent the packaging bag from being affected by its position and from drifting, thus avoiding interference with the bag-opening operation. Simultaneously, the opening of the packaging bag 12 should be lower than the support roller group 27 and enter the sealing assembly, which facilitates the blowing assembly opening the bag opening and subsequent heat sealing and bag separation.

[0035] In the preferred embodiment, see Figure 4 The drug packaging and labeling mechanism includes a mounting housing 9. A blower assembly is disposed inside the mounting housing 9. The blower assembly includes an air pump and an air nozzle 13. The air nozzle 13 is connected to the air outlet of the air pump via a pipe and is located above the opening of the packaging bag 12. A support base 28 is provided inside the mounting housing 9. A pipe is installed inside the support base 28, and the air nozzle 13 is located on the bottom surface of the support base 28. The air nozzle 13 is connected to the pipe inside the support base 28, and the pipe inside the support base 28 is also connected to the air outlet of the air pump. In this embodiment, in the horizontal direction of the support roller group 27, the air nozzle 13 is located between the feed hopper 5 and the support roller group 27, so that the air blown out by the air nozzle 13 can blow towards the opening of the packaging bag 12 that has passed the support roller group 27, ensuring that the bag opening can be blown open.

[0036] In the preferred embodiment, see Figure 5The drug packaging and labeling mechanism includes a housing 9, and an inlet support assembly including an inlet hopper 5 and a bag support assembly. One end of the inlet of the inlet hopper 5 is located outside the housing 9, and one end of the outlet of the inlet hopper 5 extends into the housing 9 and is connected to the bag support assembly. The bag support assembly includes a first rotating member 29 and a second rotating member 30. The first rotating member 29 and the second rotating member 30 are rotatably connected to the side wall of the outlet end of the inlet hopper 5, and the first rotating member 29 and the second rotating member 30 are symmetrically arranged. When the first rotating member 29 and the second rotating member 30 are not under force, the free end of the first rotating member 29 contacts the free end of the second rotating member 30 to close the outlet of the inlet hopper 5. In this embodiment, the inlet end of the feeding hopper 5 located outside the mounting housing 9 is opposite to the outlet of the spiral chute 4 of the drug conveying structure, while the outlet end of the feeding hopper 5 located inside the mounting housing 9 is connected to the bag-supporting assembly. By connecting the feeding hopper 5 and the bag-supporting assembly as one unit, the packaging bag 12 can be opened while ensuring that the drug enters the packaging bag 12 accurately. At the same time, the structure of the bag-supporting and feeding is simplified, making the structure of the drug packaging and labeling mechanism simpler and more compact. Since the first rotating member 29 and the second rotating member 30 are rotatably connected to the side wall of the outlet end of the feeding hopper 5, and the first rotating member 29 and the second rotating member 30 are symmetrically arranged... When the first rotating member 29 and the second rotating member 30 are not under force, the free end of the first rotating member 29 contacts the free end of the second rotating member 30 to close the outlet of the feed hopper 5. After the medicine enters the feed hopper 5, it falls down the feed hopper 5 to the bag support assembly. The gravity impact of the medicine when it falls causes the first rotating member 29 and the second rotating member 30 to rotate in opposite directions, thereby exposing the outlet of the feed hopper 5, so that the medicine can fall into the packaging bag 12. After the medicine has successfully entered the packaging bag 12, the first rotating member 29 and the second rotating member 30 are no longer under the action of the gravity of the medicine, so they can be reset and their free ends contact each other again to close the outlet of the feed hopper 5. This passive method of opening the bag support assembly simplifies the structure and facilitates later maintenance. Alternatively, when medicines need to be bagged, a hydraulic rod or linear motor can be used to drive the first rotating part 29 and the second rotating part 30 to rotate in opposite directions, thereby exposing the discharge port of the feed hopper 5 and facilitating the medicines to fall into the packaging bag 12. After all medicines have successfully entered the packaging bag 12, the first rotating part 29 and the second rotating part 30 are driven again by the drive mechanism to rotate and close, thus sealing the discharge port of the feed hopper 5.Specifically, the feeding support assembly also includes a lifting structure 31. The lifting structure 31 is mounted on the support base 28 connected inside the mounting housing 9 and causes the feeding hopper 5 and the bag support assembly to rise and fall. The lifting structure 31 can be an electric telescopic rod. When the free end of the first rotating member 29 and the free end of the second rotating member 30 come into contact, the side walls of the first rotating member 29 and the side walls of the second rotating member 30 form a triangle. When the first rotating member 29 and the second rotating member 30 are not under force, their free ends come into contact, forming a triangular state. As the lifting structure 31 descends, its top edge is more easily inserted into the blown-open bag opening to open the packaging bag 12. Since the first rotating member 29 and the second rotating member 30 are not under force, their free ends come into contact, forming a triangular state, and their top edge forms a straight line. This ensures that the bag opening is small and can be accurately inserted into the packaging bag 12. As the lifting structure 31 descends, the packaging bag 12 is effectively opened, preparing for the subsequent medicine to fall into the packaging bag 12.

[0037] In the preferred embodiment, see Figure 6 The drug packaging and labeling mechanism includes an installation housing 9, and a sealing assembly including a sealing machine and a support shaft 32. The sealing machine is located inside the installation housing 9 and includes a fixed sealing plate 33 and a movable sealing plate 34. The two ends of the fixed sealing plate 33 are connected to the corresponding side walls of the installation housing 9. The support shaft 32 is spaced along the length of the fixed sealing plate 33 and connected to it at intervals. The two ends of the movable sealing plate 34 are slidably fitted onto the corresponding ends of the support shaft 32. The movable sealing plate 34 and the fixed sealing plate 33 are respectively equipped with... The heating element is arranged opposite to the heating element on the movable sealing plate 34 and the heating element on the fixed sealing plate 33, or the heating element is provided on one of the movable sealing plate 34 and the fixed sealing plate 33, and the sealing element is provided on the other. Before the fixed sealing plate 33 and the movable sealing plate 34 are closed, the starting end of the packaging bag 12 extends between the fixed sealing plate 33 and the movable sealing plate 34, and the bag opening to be sealed on the packaging bag 12 is located between the two heating elements, or between the heating element and the sealing element. The principle of heat-sealing and bagging is existing technology. In this embodiment, heating elements can be installed on both the movable sealing plate 34 and the fixed sealing plate 33, or heating elements can be installed on either the movable sealing plate 34 or the fixed sealing plate 33, with a sealing element installed on the other. When the package needs to be sealed, the movable sealing plate 34 simply moves towards the fixed sealing plate 33, and then the two clamp the opening of the packaging bag 12, achieving sealing through heat sealing and dividing the packaging bag 12, so that the packaged parcel falls onto the medicine output structure for delivery. In this embodiment, the movable sealing plate 34 can be driven by a linear motor or a hydraulic telescopic rod, etc., capable of linear motion.

[0038] In the preferred embodiment, see Figure 3 The label printing and affixing component includes a label printer and a label affixing assembly. The label printer is located in the corresponding recessed area. The label affixing assembly includes a suction cup base 35 that can move relative to the label printer. A suction cup is provided on the suction cup base 35. The suction cup base 35 drives the suction cup to move to the label printer to pick up the label, and then moves between the third transmission roller group 19 and the fourth transmission roller group 20 to affix the label to the packaging bag 12. In the prior art, after the label is printed, it falls directly into the medicine receiving frame. During the falling process, the label is easily affected by airflow and cannot fall accurately into the medicine receiving frame, which makes it impossible for pharmacy staff to verify the consistency of the doctor's order, medicine, and patient. Therefore, in this embodiment, the label affixing assembly directly affixes the printed label to the packaging bag 12, effectively avoiding the aforementioned technical problems, and the structure is simple.

[0039] The drug receiving and packaging equipment of this invention has a simple and compact structure, making it very suitable for pharmacy environments with limited space.

[0040] The present invention also provides an embodiment of a control method for a drug dispensing and packaging device, see below. Figure 7 The process includes the following steps: S1. Receiving medical orders from the hospital's dispensing system and obtaining a drug list based on the medical orders; the medical orders can be from different patients or from multiple orders from the same patient; S2. Sending the obtained drug list to the drug packaging and labeling organization, which prints labels based on the received drug list and affixes them to the packaging bag 12. The labeled packaging bag 12 is then conveyed to the bottom of the drug conveying structure, and the opening of the packaging bag 12 is opened to prepare for packaging, and feedback is sent to the control unit; S3. Controlling the drug storage cabinet 1 to dispense drugs onto the drug conveying structure based on the obtained drug list, and the drugs are conveyed to the packaging bag 12 below its outlet via the drug conveying structure; S4. The drug packaging and labeling organization seals and separates the packaging bag 12 containing the drugs, causing the packaging bag 12 containing the drugs to fall onto the drug output structure and be conveyed out of the receiving and packaging equipment. The above methods can significantly reduce the use of medication receiving frames, and also avoid the problem of inconsistency between medical orders, medications, and patient information caused by the scattered label paper 23 being affected by airflow and not falling accurately into the corresponding medication receiving frame, which is common in the prior art.

[0041] In a preferred embodiment, in step S1, the number and size of the medicine boxes are analyzed based on the medical order information and compared with the drug database to determine whether all medicines in the drug list information need to be split and packaged, and to determine the number of packages after splitting. The determination result is then fed back to the hospital's dispensing system. If splitting and packaging are not required, the process proceeds to step S2 after obtaining the drug list information based on the medical order information. If splitting and packaging are required, the hospital's dispensing system matches the corresponding medical order information according to the number of packages to be split and packages, and sends the medical order information to the receiving and packaging equipment in sequence and at a predetermined time. In this embodiment, to facilitate subsequent verification of patient identity information, medication, and medical orders by doctors, each package 12 typically contains only half a bag of medication, and the package 12 is transparent for easy verification. When there are too many medications for the same patient and a single package 12 cannot be used to pack them all, the number of packages 12 to be split is determined based on the number and size of the medication boxes. The packages are then sorted as Package One, Package Two, Package Three, etc., and the number and sorting information of the split packages are sent to the hospital's medication dispensing system. The hospital's medication dispensing system then matches the corresponding medical orders based on the number of packages split and sends the medical orders to the medication receiving and packaging equipment in sequence and at a predetermined time. The predetermined time refers to the interval between the hospital's medication dispensing system sending instructions to the control unit of the medication receiving and packaging equipment. This ensures that the packaging of medications under the previous medical order is completed before the packaging of medications under the next medical order is started, avoiding confusion between medications under different medical orders and ensuring the consistency of medications, medical orders, and patient information.

[0042] In this embodiment, the packaging bags are all the same size, and their dimensions are stored in the control unit of the drug receiving and packaging equipment. The dimensions of the drug packaging box (i.e., the drug box) are also stored in the control unit. Therefore, after receiving the doctor's order information, it is only necessary to analyze and determine whether the size and quantity of the corresponding drug box are only half a bag after the packaging is completed, so that the internal drugs can be checked through the packaging bag later.

[0043] The drug receiving and packaging equipment and control method described in this invention package and seals the drugs through the packaging and sealing structure in the drug packaging and labeling mechanism, thereby eliminating the need for a drug receiving frame and the need for cleaning and disinfecting the drug receiving frame, which greatly saves labor costs and saves time and effort.
