Description

Technical Field

[0001] This invention relates to the field of dispensing equipment, and more particularly to dispensing equipment for pharmaceutical compounding centers. Background Technology

[0002] As is well known, in the application of automated equipment in centralized intravenous medication dispensing centers, the medication dispensing equipment is the core component for achieving rapid and accurate medication dispensing. Currently, such equipment typically relies on a design scheme where each dispensing compartment is equipped with an independent drive mechanism, meaning each storage unit corresponds to an independent set of actuators to achieve precise medication output control.

[0003] However, while the existing design can meet the basic drug dispensing function requirements, in actual application, the one-to-one configuration of the drive structure and the number of drug compartments results in a large number of internal components such as motors and transmission parts. This not only significantly increases the manufacturing cost and subsequent maintenance complexity of the equipment, but also reduces the overall system reliability due to physical space constraints and dense wiring. If a single drive unit fails, the corresponding drug compartment may stop, affecting the normal work process of the department. In addition, this highly distributed drive layout also limits the flexibility of modular expansion of the equipment, making it less compatible with application scenarios of different scales and drug categories.

[0004] On the other hand, existing equipment generally adopts a direct-fall or simple push-plate dispensing structure in terms of drug delivery. During the falling process, drugs are prone to collision and tumbling, which may cause packaging damage or even drug damage, especially for drugs with damaged dosage forms, posing potential drug safety hazards. Summary of the Invention

[0005] (a) Purpose of the invention In view of this, the purpose of the present invention is to provide a medicine dispensing device for a static compounding center. The dispensing cabinet in the device is provided with several sets of dispensing grids for dispensing medicine. Each set of dispensing grids has two columns, one above the other. The dispensing of medicine in the two dispensing grids in the same set and column is controlled by the same double-drive mechanism. This can reduce the number of drive structures controlling the dispensing of medicine inside the dispensing cabinet by half, thereby reducing the production cost of the entire device.

[0006] (II) Technical Solution To achieve the above technical objectives, the present invention provides a medicine dispensing device for a static compounding center, which includes a medicine dispensing cabinet and a cabinet door rotatably installed on the front side of the medicine dispensing cabinet. There is a gap between the interior of the front side of the medicine dispensing cabinet and the cabinet door. Multiple sets of medicine dispensing grids are arranged in an array along the vertical direction inside the medicine dispensing cabinet. The same set of medicine dispensing grids is arranged in two columns, and multiple medicine dispensing grids are arranged at equal intervals in the same column. Each medicine dispensing grid is provided with a push plate that can move along the length direction of the medicine dispensing grid. The medicine cabinet has an active control cavity between two medicine compartments in the same group and column. The active control cavity is equipped with two medicine dispensing control mechanisms, which are used to control the movement of the push plates inside the corresponding two medicine compartments in the same group and column. A rear equipment box is installed on the back of the medicine cabinet, and a double drive mechanism is installed in the rear equipment box. The double drive mechanism is used to drive the two medicine dispensing control mechanisms between the two medicine compartments in the same group and column.

[0007] As a further description of the above technical solution: the dispensing control mechanism includes a slider and a lead screw. The slider is slidably assembled in the movable control cavity, and a lead screw nut is embedded inside the slider. The lead screw is rotatably installed in the movable control cavity along its length. The lead screw nut is adapted to and sleeved with the lead screw. A connecting groove is formed inside the medicine distribution compartment along its length, which connects the medicine distribution compartment to the movable control cavity. One end of the push plate passes through the connecting groove and is connected to the corresponding slider. When the lead screw rotates, the slider slides along its length in the movable control cavity under the action of the lead screw nut, causing the push plate to slide in the medicine distribution compartment. When the slider moves outward, it pushes the boxed medicine in the medicine distribution compartment to move outward synchronously, thus dispensing the medicine. Conversely, when the boxed medicine is dispensed, the slider moves to the outermost end. At this time, controlling the slider to move inward allows for the replenishment of medicine into the medicine distribution compartment.

[0008] As a further description of the above technical solution: the pusher plate adopts an F-shaped structure.

[0009] As a further description of the above technical solution: the dual-drive mechanism includes a main frame and a servo motor. The main frame is fixedly installed on the back of the medicine cabinet. Two supports are respectively provided on both sides of the main frame. A movable U-shaped frame is provided on the inner side of each of the two supports. A secondary movable friction wheel is rotatably installed between the two vertical ends of the U-shaped frame. The servo motor is fixedly installed on the main frame. An active friction wheel is rotatably installed on the inner side of the main frame. The output shaft of the servo motor is connected to the rotating shaft of the active friction wheel. One end of each of the two lead screws corresponding to the two medicine cabinets in the same group and column extends into the rear equipment box. A driven friction wheel is sleeved on the end of each of the two lead screws extending into the rear equipment box. Both driven friction wheels are parallel to the active friction wheel. There is a gap between them. Both of the two secondary movable friction wheels can simultaneously contact or separate the driven friction wheel and the active friction wheel on the corresponding lead screw under the movement control of the U-shaped frame. When the servo motor is running, it can drive the active friction wheel to rotate. When the medicine rack in the same group and column needs to dispense medicine, the lead screw corresponding to it needs to rotate. At this time, the secondary movable friction wheel between the driven friction wheel and the active friction wheel on the lead screw moves, so that the driven friction wheel and the active friction wheel form a linkage transmission structure under the contact friction force of the secondary movable friction wheel, thereby driving the lead screw to rotate, so that it drives the push plate in the corresponding medicine rack to move one unit, and then dispenses medicine. After the medicine is dispensed, the secondary movable friction wheel moves again and separates from the driven friction wheel and the active friction wheel. At this time, there is no transmission between the driven friction wheel and the active friction wheel, and the medicine dispensing stops.

[0010] As a further description of the above technical solution: an electric push rod is installed on the outer side of the bracket, and two upright plates are installed on the inner side of the bracket. The U-shaped frame is movably installed between the two upright plates. The piston rod of the electric push rod is centrally connected to one end of the U-shaped frame. Based on this, when the electric push rod is running, it can push the U-shaped frame to move closer to or away from the driven friction wheel and the active friction wheel, thereby realizing the contact or separation control between the secondary active friction wheel and the driven friction wheel and the active friction wheel.

[0011] As a further description of the above technical solution: the surface of the U-shaped frame is provided with a guide groove along the moving direction of the U-shaped frame, and the inner side of the upright plate is provided with a guide plate adapted to the guide groove. The guide plate is slidably installed in the guide groove. When the U-shaped frame moves, the moving direction of the secondary movable friction wheel will not be deviated by the limiting control of the guide groove and the guide plate, and the movement is stable and accurate.

[0012] As a further description of the above technical solution: a medicine dispenser is installed on one side of the cabinet door, and a circulating conveyor belt capable of transporting medicine to the medicine dispenser is provided on the inner side of the cabinet door. A housing is provided on the outside of the cabinet door, and a motor for driving the circulating conveyor belt is installed inside the housing. The circulating conveyor belt adopts a continuous S-shaped structure, so that the circulating conveyor belt can pass through the area below each row of medicine racks, and the circulating conveyor belt on the outer side of each row of medicine racks can transport medicine towards the medicine dispenser. Based on this, when medicine is pushed out from the medicine rack, it can directly reach the top of the circulating conveyor belt and be transported into the medicine dispenser under the action of the circulating conveyor belt.

[0013] As a further description of the above technical solution: the inside of the medicine dispenser is provided with a medicine collection channel in the vertical direction, and the inside of the medicine dispenser is provided with a medicine dispensing channel at the position of each medicine rack. The medicine dispensing channel adopts an inclined structure in the horizontal direction, with the height gradually decreasing from the direction close to the medicine rack to the direction away from the medicine rack. Therefore, the circulating conveyor belt can directly transport the medicine into the medicine collection channel, thereby realizing rapid medicine collection and dispensing.

[0014] As a further description of the above technical solution: the inside of the medicine collection channel is equipped with multiple buffer plates with an inclined structure. The bottom of the buffer plate is provided with a buffer spring. The buffer plate can push the buffer spring to keep it parallel to the lower opening of the medicine outlet channel without being disturbed by external forces, and can gradually rotate to release the medicine when affected by the gravity of the medicine.

[0015] As a further description of the above technical solution: a base plate frame is suspended at the bottom of the medicine dispenser, and a medicine receiving hopper is placed on top of the base plate frame, so that medicine can be directly and centrally collected, making the operation convenient and quick.

[0016] In the above technical solution, the medicine dispensing equipment for the static compounding center provided by the present invention has a dispensing cabinet with several sets of dispensing grids inside. Each set of dispensing grids has two columns, one above the other. The dispensing of medicine in the two dispensing grids in the same set and column is controlled by the same double-drive mechanism. This reduces the number of drive structures controlling the dispensing of medicine inside the dispensing cabinet by half, thereby reducing the production cost of the entire equipment and reducing the redundancy of the equipment, making the equipment more compatible. The dispensing cabinet is designed with an S-shaped continuous circulating conveyor belt, which, together with the dispensing device, forms a complete dispensing link, which facilitates dispensing of medicine. Furthermore, the structural design of the dispensing device makes it less likely for the medicine to be damaged when it falls. Attached Figure Description

[0020] The following description is exemplary in nature and is not intended to limit the scope, application, or use of this disclosure. It should be understood that in all these figures, the same or similar reference numerals indicate the same or similar parts and features. The figures are merely schematic representations of the concept and principles of embodiments of this disclosure and do not necessarily show the specific dimensions and scale of the various embodiments of this disclosure. Certain details or structures of embodiments of this disclosure may be exaggerated in particular portions of certain figures.

[0021] like Figures 1-10 As shown: This embodiment provides a technical solution: a medicine dispensing device for a static compounding center, including a medicine dispensing cabinet 1 and a cabinet door 2 rotatably installed on the front side of the medicine dispensing cabinet 1. There is a gap between the interior of the front side of the medicine dispensing cabinet 1 and the cabinet door 2. Multiple sets of medicine dispensing grids 10 are arranged in an array along the vertical direction inside the medicine dispensing cabinet 1. The same set of medicine dispensing grids 10 is arranged in two columns, and multiple medicine dispensing grids 10 are arranged at equal intervals in the same column. Each medicine dispensing grid 10 is provided with a push plate 120 that can move along the length direction of the medicine dispensing grid 10. The medicine cabinet 1 has a movable control cavity 12 located between two medicine compartments 10 in the same group and column. The movable control cavity 12 is equipped with two medicine dispensing control mechanisms 6. The two medicine dispensing control mechanisms 6 are used to control the movement of the push plate 120 inside the two medicine compartments 10 in the same group and column respectively. The back of the medicine cabinet 1 is equipped with a rear equipment box 4. The back of the medicine cabinet 1 is equipped with a double drive mechanism 5 located in the rear equipment box 4. The double drive mechanism 5 is used to drive the two medicine dispensing control mechanisms 6 between the two medicine compartments 10 in the same group and column. Working principle: When the medicine cabinet 1 is in use, various boxed medicines are placed in each medicine compartment 10. When it is necessary to take out the medicine from the corresponding medicine compartment 10, the double drive mechanism 5 on the back of the medicine cabinet 1 is activated, which controls the corresponding medicine dispensing control mechanism 6 to operate. The corresponding medicine dispensing control mechanism 6 controls the push plate 120 inside the medicine compartment 10 to move one unit distance. At this time, the boxed medicine at the front of the medicine compartment 10 falls from the gap between the front side of the medicine cabinet 1 and the cabinet door 2, thus dispensing the medicine. In summary: The medicine cabinet 1 has several sets of medicine display compartments 10 inside, and each set of medicine display compartments 10 has two columns, one above the other. The medicine dispensing from the two medicine display compartments 10 in the same set and column is controlled by the same double-drive mechanism 5. This reduces the number of drive structures controlling the dispensing of medicine inside the medicine cabinet 1 by half, thereby reducing the overall production cost of the equipment and reducing redundancy, making the equipment more compatible.

[0022] Specifically, such as Figures 5-9 As shown, to achieve drug dispensing, in this embodiment, the drug dispensing control mechanism 6 includes a slider 60 and a lead screw 62. The slider 60 is slidably mounted within the movable control cavity 12. A lead screw nut 61 is embedded inside the slider 60. The lead screw 62 is rotatably mounted within the movable control cavity 12 along its length. The lead screw nut 61 and the lead screw 62 are adapted to and interlocked. A connecting groove 100 is formed inside the drug-dispensing grid 10 along its length, connecting the drug-dispensing grid 10 to the movable control cavity 12. One end of the push plate 120 passes through the connecting groove 100 and connects to the corresponding slider 60. Therefore, when the lead screw 62 rotates, under the action of the lead screw nut 61, the slider 60 slides along the length direction in the movable control cavity 12, driving the push plate 120 to slide in the medicine rack 10. When the slider 60 moves outward, it pushes the boxed medicine in the medicine rack 10 to move outward synchronously, realizing the dispensing of medicine. Conversely, when the boxed medicine is dispensed, the slider 60 moves to the outermost end. At this time, controlling the slider 60 to move inward can replenish the medicine in the medicine rack 10 again. It should also be noted that in the medicine dispensing control mechanism 6 of the two medicine racks 10 in the same group and column, the two lead screws 62 are parallel and on the same horizontal plane.

[0023] Specifically, such as Figures 5-9 As shown, in order to facilitate dispensing of boxed medicines of different heights, the pusher plate 120 adopts an F-shaped structure in this embodiment.

[0024] Specifically, such as Figures 5-9As shown, in order to achieve the control of medicine dispensing from two medicine storage compartments 10 in the same group and column using the same double-drive mechanism 5, and to ensure that there is no mutual interference during control, in this embodiment, the double-drive mechanism 5 includes a main frame 50 and a servo motor 57. The main frame 50 is fixedly installed on the back of the medicine storage cabinet 1. Two supports 51 are respectively provided on both sides of the main frame 50. A movable U-shaped frame 53 is provided on the inner side of each of the two supports 51. A secondary movable friction wheel 54 is rotatably installed between the two vertical ends of the U-shaped frame 53. The servo motor 57 is fixedly installed on the main frame 50, and a servo motor 57 is rotatably installed on the inner side of the main frame 50. The output shaft of the servo motor 57 is connected to the rotating shaft of the active friction wheel 56. One end of the two lead screws 62 corresponding to the two medicine racks 10 in the same group and column extends into the rear equipment box 4. The two lead screws 62 extending into the rear equipment box 4 are each sleeved with a driven friction wheel 55. The two driven friction wheels 55 are parallel to the active friction wheel 56. There is a gap between the two driven friction wheels 55 and the active friction wheel 56. The two secondary movable friction wheels 54 can simultaneously contact or separate the driven friction wheel 55 and the active friction wheel 56 on the corresponding lead screw 62 under the movement control of the U-shaped frame 53.

[0025] Based on this, when the servo motor 57 is running, it can drive the active friction wheel 56 to rotate. When the medicine rack 10 in the same group and column needs to dispense medicine, the corresponding lead screw 62 needs to rotate. At this time, the secondary movable friction wheel 54 between the driven friction wheel 55 and the active friction wheel 56 on the lead screw 62 moves, so that the driven friction wheel 55 and the active friction wheel 56 form a linkage transmission structure under the contact friction force of the secondary movable friction wheel 54 (e.g., Figure 9 (as shown in the image), which in turn drives the lead screw 62 to rotate, causing it to move the push plate 120 in the corresponding medicine dispensing compartment 10 by one unit, thus dispensing the medicine. After dispensing the medicine, the secondary movable friction wheel 54 moves again, separating from the driven friction wheel 55 and the driving friction wheel 56 (as shown in the image). Figure 10 (as shown in the image) At this position, there is no transmission between the driven friction wheel 55 and the driving friction wheel 56, and the dispensing of medicine stops.

[0026] Additionally, it should be noted that the two secondary moving friction wheels 54 in the double-drive mechanism 5 correspond to the driven friction wheels 55 on the two lead screws 62 of the two medicine racks 10 in the same group and column.

[0027] To facilitate the installation of multiple double-drive mechanisms 5 in the same column and avoid mutual interference between adjacent double-drive mechanisms 5, in this embodiment, multiple double-drive mechanisms 5 in the same column are installed in a staggered manner, which can avoid mutual interference and facilitate the maintenance, installation and replacement of the mechanisms.

[0028] It should also be noted that: because the dispensing speed is relatively slow, the inertia of the medicine box during dispensing is negligible. Since the driven friction wheel 55 rotates slowly during dispensing, when the secondary movable friction wheel 54 separates and the driven friction wheel 55 loses power, the driven friction wheel 55 will quickly stop rotating due to the reaction force transmitted by the friction of the medicine box. Therefore, it will not cause any additional medicine to be pushed out by inertia. Finally, the dispensing speed is related to the rotational speed of the lead screw 62, which in turn is related to the transmission ratio of the secondary movable friction wheel 54 to the driven friction wheel 55 and the driving friction wheel 56. Therefore, the diameter parameters and surface friction coefficients of the secondary movable friction wheel 54, driven friction wheel 55, and active friction wheel 56 can be designed and adjusted according to actual needs. Finally, since the width of the medicine box varies, the unit length defined for each medicine rack 10 is different. Based on this, the pushing unit stroke of each push plate 120 is different. Therefore, when setting the pushing unit distance of each medicine rack 10, the pushing unit distance can be controlled by setting the unit contact time between each secondary movable friction wheel 54 and the driven friction wheel 55 and active friction wheel 56.

[0029] Specifically, such as Figures 5-9 As shown, in order to achieve the movement control of the secondary movable friction wheel 54, in this embodiment, an electric push rod 52 is installed on the outer side of the bracket 51, two upright plates 510 are installed on the inner side of the bracket 51, and a U-shaped frame 53 is movably installed between the two upright plates 510. The piston rod of the electric push rod 52 is connected to the center of one end of the U-shaped frame 53. Based on this, when the electric push rod 52 is running, it can push the U-shaped frame 53 to move closer to or away from the driven friction wheel 55 and the active friction wheel 56, thereby realizing the contact or separation control of the secondary movable friction wheel 54 with the driven friction wheel 55 and the active friction wheel 56.

[0030] Specifically, such as Figures 5-9 As shown, in order to ensure the stable movement of the secondary movable friction wheel 54, and thus ensure that the secondary movable friction wheel 54 can contact the driven friction wheel 55 and the driving friction wheel 56 simultaneously, so as to stabilize the transmission, in this embodiment, a guide groove 530 is provided on the surface of the U-shaped frame 53 along the moving direction of the U-shaped frame 53, and a guide plate 5100 adapted to the guide groove 530 is provided on the inner side of the upright plate 510. The guide plate 5100 is slidably installed in the guide groove 530. Based on this, when the U-shaped frame 53 moves, the moving direction of the secondary movable friction wheel 54 will not deviate through the limiting control of the guide groove 530 and the guide plate 5100, and the movement is stable and accurate.

[0031] Specifically, such as Figures 1-4As shown, in order to facilitate dispensing medicine, in this embodiment, a medicine dispenser 3 is installed on one side of the cabinet door 2, and a circulating conveyor belt 23 is provided on the inner side of the cabinet door 2 to transport medicine to the medicine dispenser 3. A housing 20 is provided on the outside of the cabinet door 2, and a motor for driving the circulating conveyor belt 23 is installed inside the housing 20. The circulating conveyor belt 23 adopts a continuous S-shaped structure, so that the circulating conveyor belt 23 can pass through the area below each row of medicine racks 10, and the circulating conveyor belt 23 on the outer side of each row of medicine racks 10 can transport medicine towards the medicine dispenser 3. Based on this, when medicine is dispensed from the medicine racks 10, it can directly reach the top of the circulating conveyor belt 23 and be transported into the medicine dispenser 3 under the action of the circulating conveyor belt 23.

[0032] Specifically, such as Figure 4 As shown, in order to facilitate the collection of medicine, in this embodiment, the medicine dispenser 3 has a medicine collection channel 30 opened in the vertical direction inside. The medicine dispenser 3 has a medicine dispensing channel 31 at the position of each medicine rack 10 inside. The medicine dispensing channel 31 adopts an inclined structure in the horizontal direction, with the height gradually decreasing from the direction close to the medicine rack 1 to the direction away from the medicine rack 1. Therefore, the circulating conveyor belt 23 can transport the medicine to the medicine collection channel 30 through the medicine dispensing channel 31, thereby realizing rapid medicine collection and dispensing.

[0033] Specifically, such as Figures 1-4 As shown, due to the height of the medicine cabinet 1, in order to avoid the medicine falling too far and causing damage, in this embodiment, multiple inclined buffer plates 32 are installed inside the medicine collection channel 30. A buffer spring 33 is provided at the bottom of the buffer plate 32. The buffer plate 32 can push the buffer spring 33 to keep it parallel to the lower opening of the medicine dispensing channel 31 without being disturbed by external forces. It can also gradually rotate to release the medicine when affected by the weight of the medicine. In addition, it should be noted that the cross-section of the medicine collection channel 30 and the medicine dispensing channel 31 is much larger than the cross-section of all medicine boxes, so there will be no situation of medicine getting stuck.

[0034] Specifically, such as Figures 1-4 As shown, in order to facilitate the collection of medicine, in this embodiment, a base plate frame 35 is suspended at the bottom of the medicine dispenser 3, and a medicine receiving hopper 34 is placed on top of the base plate frame 35. This allows for direct and centralized collection of medicine, making the operation convenient and quick.

[0035] It should also be noted that: Figure 2As shown, each medicine cabinet 1 has an indicator panel 11 embedded in the front of each movable control cavity 12. A displacement sensor is installed on the back of the indicator panel 11. The displacement sensor can sense the position of two sliders 60 inside the movable control cavity 12 in real time, and obtain the quantity of medicine in the corresponding medicine compartment 10 based on the position of the sliders 60. This quantity is then displayed on the indicator panel 11 in real time for easy replenishment. An alarm light can also be installed on the indicator panel 11. When the quantity of medicine in the corresponding medicine compartment 10 falls below a preset value, it reminds staff to replenish the medicine promptly. Figure 1 As shown, a lens 21 is embedded on the surface of the cabinet door 2 at the front side of the indicator panel 11, and the display of the indicator panel 11 can be easily observed through the lens 21.

[0036] The exemplary implementation of the solution proposed in this disclosure has been described in detail above with reference to preferred embodiments. However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the spirit of this disclosure, and various combinations can be made to the various technical features and structures proposed in this disclosure without exceeding the protection scope of this disclosure, which is determined by the appended claims.
