Description

Technical Field

[0001] This invention relates to the field of pharmaceutical storage, and in particular to a refrigerated medicine storage door structure and its usage method. Background Technology

[0002] Traditional medicine cabinet doors include drawer type, hinged type, rotating type, sliding type, folding type, and roller shutter type. Due to the door structure, these traditional opening methods usually require a large angle or space to open. However, the medicine box is usually small in size, and it is not necessary to open the door too much to take out the medicine. This excessive door opening space will cause too much leakage of cold air in the refrigerated medicine cabinet when taking out the medicine.

[0003] When users operate automated medicine dispensers, frequent and excessive opening and closing of the dispenser door can cause excessive leakage of refrigerated air. In severe cases, excessive leakage of cold air may form condensation droplets around the equipment, making the floor slippery. If the condensation droplets flow back into the unit, they may freeze inside the refrigerator, freezing the medicine boxes or door opening mechanisms, potentially causing malfunctions in the automated medicine dispensing device. If the water droplets flow back into the medicine boxes, they may soak the medicine packaging or even damage the medicine. A prolonged damp and cold environment may also accelerate corrosion of the internal structure of the equipment, reducing its lifespan. Excessive leakage of refrigerated air also increases the workload of the refrigeration unit, increasing the equipment's power consumption.

[0004] For outward-opening door types, such as drawer-type, hinged, and rotating types, such door structures require a large external opening space. Furthermore, outward-opening door structures can hinder the movement of the medicine-retrieving handle to some extent. Outward-opening door structures require the device to reserve more opening space, which is not conducive to the rational utilization of the device space.

[0005] Regarding the top-and-bottom opening method, such as the automatic three-door rapid lifting structure disclosed in patent CN215859789U, the staggered three-door configuration cannot meet the opening requirements of the refrigerated medicine compartment. This is because the refrigerator in the medicine compartment is usually divided into multiple layers to store various types of medicines. If the opening structure is set according to the existing technology, the structure of the drive device in the staggered structure of the medicine compartment doors will be more complex, the overall space of the compartment will be irregular, the space occupied will be increased, and it will be difficult to meet the airtightness requirements of the refrigerator compartment door, which will make it easier for refrigerated air to leak.

[0006] Therefore, designing an automatic door opening structure for medicine storage that is highly automated, requires minimal opening space, opens accurately and quickly, and has a short response time is an urgent problem to be solved. Summary of the Invention

[0007] This invention addresses the shortcomings of existing technologies by providing a refrigerated medicine storage door structure.

[0018] As a further improvement of the present invention, a bottom gate is also fixed on the guide rod. The bottom gate is located at the lower end of the bottommost medicine compartment gate and at the lower end of the bottommost compartment in the refrigerated medicine compartment.

[0019] As a further improvement of the present invention, the medicine storage gate includes a storage gate plate and a guide block disposed on the storage gate plate. The guide rod connects the medicine storage gate in series through the guide block, and the storage gate plate is provided with a guide hole for the guide shaft to extend into.

[0020] As a further improvement of the present invention, there are two telescopic components, and the distance between the two telescopic components is adjustable.

[0064] To make the objectives, technical solutions, and advantages of this invention clearer, the specific embodiments of this invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of this invention, not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0065] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for 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 limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0066] 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. Furthermore, the technical features involved in the different embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.

[0067] like Figures 1 to 5 As shown, the refrigerated medicine compartment door structure designed in this application includes a frame and several medicine compartment gates 300 disposed within the frame. The several medicine compartment gates 300 are connected in series via guide rods 310 and stacked vertically. When one medicine compartment gate 300 is lifted, if there are other medicine compartment gates 300 above it, they will also be lifted. Furthermore, a drive device is included within the frame. The drive device includes a lifting module and a telescopic module. The lifting module includes a lifting motor 100 and a lifting assembly. The refrigerated medicine compartment can have only one lifting assembly on one side, or two lifting assemblies symmetrically arranged on both sides. The telescopic module includes a fixing component 200 and a telescopic assembly. Two telescopic assemblies can be provided, including an upper telescopic assembly and a lower telescopic assembly. The distance between the two telescopic assemblies can be adaptively adjusted according to the required opening height. The preferred distance is slightly greater than the height required for the mechanical gripper to grasp the medicine plus the height of one medicine compartment gate 300. The fixing component 200 connects the telescopic assembly to the lifting assembly, and is driven by the lifting assembly to perform upward or downward movements. The frame of the refrigerated medicine compartment door structure provides stable support for devices such as the lifting motor 100, lifting assembly, and guide rod 310. The drive device drives at least one medicine compartment gate 300 to operate. When it is necessary to open a medicine compartment gate 300 at a certain position to retrieve medicine, the lifting module in the drive device quickly moves the telescopic module to the corresponding position of the medicine to be retrieved. The telescopic module extends into the corresponding medicine compartment gate 300, and then the lifting module drives the telescopic module to lift up, raising the corresponding medicine compartment gate 300 or the corresponding medicine compartment gate 300 and all medicine compartment gates 300 above it to a certain position, so that the mechanical medicine retrieval gripper can reach into the medicine compartment to perform the medicine retrieval operation. Each time medicine is retrieved, only the medicine compartment gate 300 at the corresponding position of the medicine in the refrigerator is opened. After the medicine is retrieved, the lifting device lowers all the raised medicine compartment gates 300 and retracts the extended telescopic assembly.

[0068] like Figure 2 and Figure 5As shown, the lifting motor 100 can be installed on the top of the refrigerator or in other locations, supported by a horizontal base plate. One lifting motor 100 can simultaneously power two lifting components on both sides of the refrigerator. The lifting motor 100 and the lifting components are connected by a lifting drive shaft 101 located below the horizontal base plate, ensuring synchronized lifting movements of the lifting components on both sides of the refrigerated medicine compartment. The lifting motor 100 is connected to the lifting drive shaft 101 via a transmission belt 102. The lifting components include a lifting belt 110, a lifting guide rail 120, and a slider 121 mounted on the lifting guide rail 120. One end of the lifting belt 110 is connected to the lifting drive shaft 101, and the other end is connected to an idler pulley assembly 111. The idler pulley assembly 111 is located at the bottom, facilitating adjustment of the slack of the lifting belt 110 by personnel during equipment installation or maintenance.

[0069] like Figures 6 to 8 As shown, the telescopic module includes a fixed component 200 and at least one telescopic component. The fixed component 200 is driven to rise or fall by several synchronous belt clamps 112 on the lifting belt 110. The fixed component 200 is mounted on the slider 121. The fixed component 200 includes a slider fixing plate 210, a slider support plate 211, a telescopic motor fixing plate 212, several support columns 213, and a guide shaft fixing plate 214. The synchronous belt clamps 112 and the slider 121 are fixed on the slider fixing plate 210. The telescopic component includes a telescopic motor 220, a fixed shaft, and a guide shaft 223 located at the output end of the telescopic motor. The fixed shaft includes a front fixed shaft 221 and a rear fixed shaft 222. The specific connection relationship is as follows: Figure 6 As shown. The telescopic motor 220 drives the guide shaft 223 to perform telescopic movements. When two telescopic components are configured vertically on a fixed component 200, the distance between the two telescopic components can be adjusted according to the actual door opening needs. Preferably, the distance between the two telescopic components is preset during production according to the corresponding cold storage compartment, but the user can also adjust it according to the door opening needs. For example, when a larger mechanical gripper is needed or the stored medicines are larger, the distance can be increased accordingly to meet the needs of retrieving the medicines. Preferably, when the telescopic component extends, it controls the guide shaft 233 to extend into the guide hole 322 at the center of the side of the medicine compartment gate 300.

[0070] like Figure 9 and Figure 10As shown, the slider fixing plate 210 is also equipped with several fixing brackets 230, each of which is fixed with a proximity sensor 231. The proximity sensor 231 is located at the rear end of the telescopic motor 220 and is used to sense the amount of rotation of the fixed shaft rear shaft 222. Each telescopic component has a corresponding proximity sensor 231. After one door opening action is completed, it is used to detect whether the telescopic rod of the telescopic motor 220 has been fully reset. The slider fixing plate 210 is also equipped with a module sensing plate 134. Several position sensing sensors 131 corresponding to the module sensing plate are set on the refrigerator or door frame to sense the up and down movement position of the telescopic component. This helps to position the medicine compartment gate 300 when it is opened and to control the lifting amount of the medicine compartment gate 300, thus helping to ensure the accuracy of the medicine compartment door opening.

[0071] like Figure 4 As shown, all medicine storage gates 300 are connected in series via guide rods 310 and stacked together. Each medicine storage gate 300 can slide independently on the guide rods 310. A top fixing block 311 is provided at the top of the guide rods 310. To fully meet the opening requirements, there is a certain distance between the top fixing block 311 and the uppermost medicine storage gate 300, which is not less than the height of one maximum cold storage compartment. This satisfies both the need to open the door to retrieve medicine and the need to quickly replenish medicines. The bottom of the guide rod 310 is provided with a bottom fixing block 312, and a bottom gate 313 is also fixed on the guide rod 310. The bottom gate 313 is located between the bottom fixing limit block 312 and the bottom medicine compartment gate 300, and the bottom gate 313 is located at the bottom end of the bottom compartment in the refrigerated medicine compartment. The bottom gate 313 has a similar structure to the medicine compartment gate 300 but is smaller in size, and a sealing strip is provided on the top layer. The contact between the bottom medicine compartment gate 300 and the bottom medicine compartment gate 300 is soft and has good sealing performance. Two guide rods 310 can be provided and fixed on both sides of the medicine compartment gate 300 respectively.

[0072] like Figures 11 to 12 As shown, the medicine storage gate 300 includes a gate panel and a guide block 320 disposed on the gate panel. A bearing 321 is disposed on the guide block 320. A guide hole 322 is disposed on the gate panel, preferably located at the center of the side of the gate panel. The guide hole 322 can cooperate with the guide shaft 223 in the telescopic assembly. When the gate needs to be opened, the lifting assembly first raises or lowers the telescopic assembly to a suitable position, and then the telescopic motor 220 in the telescopic assembly inserts the guide shaft 223 into the guide hole 322. Afterwards, the lifting assembly drives the medicine storage gate 300 to perform a raising or lowering action. Figure 10 and Figure 11As shown, the door panel specifically includes an outer sealing plate 331, an inner sealing plate 332, a heat insulation plate 333, an inner sealing plate 334, a glue sealing plate 335, an upper sealing plate 336, and a lower sealing plate 337. The heat insulation plate 333 is located in the middle of the door panel and can provide a certain degree of heat insulation for the entire refrigerated medicine compartment, reducing the transfer of external heat. The glue sealing plate 335 is located at the upper part of the door panel to enhance the airtightness between the medicine compartment gates 300, and also plays a buffering role.

[0073] like Figure 9 As shown, it also includes at least one cable chain unit, which includes a cable chain 132, a cable chain groove 130 and a cable chain movable plate 133. The power supply wires of the telescopic motor 220 and proximity sensor 231 and other electrical devices in the telescopic device are connected to the cable chain. Preferably, two cable chain units are arranged symmetrically on both sides of the refrigerator.

[0074] like Figure 13 As shown, since the size of the shelves inside the refrigerator and the external medicine compartment door 300 are not necessarily the same, a medicine compartment door 300 may be larger or smaller than the shelves inside the refrigerator. Therefore, the upper and lower edges of the medicine compartment door 300 are not necessarily flush with the inner shelves of the refrigerator. When opening the medicine compartment door 300 to retrieve medicine, aligning the inner shelf of the refrigerator with the upper edge of the lower medicine compartment door 300 helps reduce the risk of medicine falling when the medicine retrieval gripper grabs the medicine. The refrigerator medicine compartment door structure designed in this application has multiple optional opening methods. The common feature is that the door is opened only to an appropriate height each time. While meeting the height requirement for the mechanical gripper to grab the medicine, the opening height is kept as small as possible to reduce the leakage of refrigerated air inside the refrigerator compartment.

[0075] like Figure 14 As shown, this application also provides an automated cold storage medicine warehouse, including a cold storage medicine warehouse frame 400, cold storage compartments 401, cold storage medicine warehouse door structures 402, an automatic medicine dispensing device 403, and a control console 404. The automated cold storage medicine warehouse includes five horizontally distributed cold storage compartments 401, each with a corresponding cold storage medicine warehouse door structure 402. Based on user needs, the control console 404 analyzes the user's requirements and controls the opening of the cold storage medicine warehouse door structure 402, allowing the automatic medicine dispensing device 403 to reach into the cold storage compartment 401 and retrieve the medicine for the user.

[0076] As an optional implementation, when there is only one telescopic component in the telescopic module, the specific opening method of the refrigerated medicine compartment door structure of this application is as follows:

[0077] T10. When medication needs to be retrieved, the console receives user instructions and identifies the location of the item to be retrieved in the corresponding compartment of the refrigerated medicine compartment, and identifies the medicine compartment gate 300 that needs to be opened to retrieve or replenish the item in the compartment.

[0078] T20. The lifting motor 100 in the lifting module of the drive device drives the lifting drive shaft 101 through the transmission belt 102. The lifting drive shaft 101 drives the lifting belts 110 on both sides. The synchronous belt plate clamps 112 on the lifting belts 110 on both sides drive the fixing component 200 of the telescopic module to move up or down in the lifting guide rail 120 to the position of the medicine storage gate 300 corresponding to the target medicine, so that the guide shaft 223 in the telescopic component is aligned with the guide hole 322 of the medicine storage gate 300.

[0079] T21. The telescopic motor 220 of the telescopic assembly controls the guide shaft 223 to extend into the guide hole 322 of the corresponding medicine storage gate 300;

[0080] T22. The lifting motor 100 drives the corresponding medicine storage gate 300 and the medicine storage gate 300 above it (if any) to move upward simultaneously to the height of the minimum space required to pick up or replenish items so that the mechanical gripper can pick up the medicine.

[0081] T30. After the mechanical gripper finishes taking the medicine, the lifting motor 100 drives the lifting belt 110 to lower the medicine bin gate 300 to its original position along the lifting guide rail 120.

[0082] T31. The telescopic motor 220 of the telescopic assembly pulls the guide shaft 223 out from the guide hole of the medicine storage gate 300, and completes the full reset of the guide shaft 223 with the help of the proximity sensor 231.

[0083] As an optional implementation, when the telescopic component in the telescopic module has two parts, one above the other, the specific opening method of the refrigerated medicine compartment door structure of this application is as follows:

[0084] E10. When medication needs to be retrieved, the console receives user instructions and identifies the location of the item to be retrieved in the corresponding compartment of the refrigerated medicine compartment, and identifies the medicine compartment gate 300 that needs to be opened to retrieve or replenish the item in the compartment.

[0085] E11. Identify the height of the minimum retrieval space required for medicine retrieval, and adjust the distance between the upper and lower telescopic components so that the distance between two adjacent medicine compartment gates 300 when they are opened is greater than or equal to the height of the minimum retrieval space.

[0086] E20. The lifting motor 100 in the lifting module of the drive device drives the lifting drive shaft 101 through the transmission belt 102. The lifting drive shaft 101 drives the lifting belts 110 on both sides. The synchronous belt plate clamps 112 on the lifting belts 110 on both sides drive the fixing component 200 of the telescopic module to move up or down in the lifting guide rail 120 to the refrigerator compartment where the target medicine is located, so that the guide shaft 223 in the upper telescopic component is aligned with the guide hole 322 of the medicine compartment gate 300.

[0087] E21. The guide shaft 223 is controlled by the telescopic motor 220 of the upper telescopic assembly to extend into the guide hole 322 of the corresponding medicine storage gate 300.

[0088] E22. The lifting motor 100 drives the corresponding medicine compartment gate 300 and its upper medicine compartment gate 300 (if any) to move upwards simultaneously by a certain distance. At this time, the medicine compartment gate 300 that has not moved on the next level is not necessarily flush with the partition of the corresponding inner compartment of the refrigerator. If the upper sealing plate 335 of the medicine compartment gate 300 that has not moved on the next level is lower than the lower compartment plate in the corresponding inner compartment of the refrigerator, there will be a section suspended when the mechanical gripper retrieves the medicine, which may pose a risk of the medicine falling. In order to make the upper sealing plate 335 of the medicine compartment gate 300 that has not moved on the next level flush with the lower compartment plate in the corresponding inner compartment of the refrigerator, the lifting motor 100 continues to drive the telescopic module to move upwards until the guide shaft 223 of the lower telescopic component is directly opposite the guide hole 322 of the medicine compartment gate 300 that has not moved on the next level.

[0089] E23, The guide shaft 223 is controlled by the telescopic motor 220 of the lower telescopic assembly to extend into the guide hole 322 of the unmoved medicine warehouse gate 300 of the next layer;

[0090] E24. The lifting motor 100 continues to operate, simultaneously raising the upper medicine compartment gate 300 and the lower medicine compartment gate 300 until the upper sealing plate 335 of the lower medicine compartment gate 300 is flush with the lower compartment plate in the corresponding refrigerator compartment. At this point, because the refrigerator compartment plate and the sealing plate 335 are flush, there is not much medicine hanging in the air when the mechanical gripper retrieves the medicine, preventing the medicine from falling into the automated refrigerated medicine compartment device.
