Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of intelligent cabinets, in particular to an intelligent cabinet capable of quickly switching between multiple types of access ports. BACKGROUND

[0002] With the rapid development of e-commerce and changes in consumption patterns, traditional retail and warehousing methods are facing enormous challenges and transformation needs. Especially in the context of accelerating urbanization, the scarcity of space resources makes goods storage and distribution increasingly complex. Therefore, as a new retail and distribution solution, intelligent cabinets are gradually being widely used in various scenarios.

[0003] In the application of intelligent cabinets, a large number of goods are often stored in the cabinet, but different goods have different storage environments, such as goods that need to be refrigerated and goods that need to be stored at room temperature. When accessing goods, different access ports are often needed for operation. The existing intelligent cabinets often only have one access port, which cannot be used for goods with different storage conditions. For example, certain goods (such as medicines) have strict requirements for storage environment. If these standards are not followed, changes in storage environment during the picking process may cause damage to the goods.

[0004] For example, a Chinese utility model patent with publication number CN218512997U and the patent name of a single-port multi-warehouse device, which specifically discloses a technical solution comprising a shell, a take-out door, a touch screen, and a code scanner arranged in sequence on the outer surface of one side wall of the shell, and an electric drive rotating shaft rotatably arranged in the middle of the inner cavity of the shell, a storage cabinet fixedly connected to the bottom of the positioning carrier rod, and a central processing unit fixedly arranged at the bottom of the inner cavity of the shell.

[0005] The above-mentioned scheme adopts fixed single-port picking, and the internal design is a rotatable multiple storage cabinet. The single take-out door solves the problem of finding the corresponding cabinet in front of each cabinet to get the goods when picking up independently on the market, achieving the effect of convenient and fast picking. It also solves the problem of needing to walk around to find the open cabinet when there are multiple access needs, making access easy. The storage cabinet can be directly operated from a single port, and the switching of the storage cabinet uses an elliptical Ferris wheel type switching method to quickly find the required storage cabinet and send it to the take-out door.

[0006] However, this scheme uses an "elliptical Ferris wheel type" rotating structure, which rotates the ring-shaped flexible disc belt through an electric drive rotating shaft, so that multiple storage cabinets are aligned in sequence with a single access port. The advantage is that users do not need to move to access goods in different storage cabinets, but there are the following problems:

[0007] First of all, all storage cabinets are exposed to the same cavity, and the temperature and humidity cannot be independently controlled (such as mixing refrigerated cabinets with normal temperature cabinets), resulting in loss of control over the storage conditions of special goods such as medicines and fresh food;

[0008] Second, the dynamic stability is insufficient, that is, the goods inertia swing (especially liquid goods) in the rotation process, depending on the gravity sensing bottom trigger emergency stop, prone to mechanical failure;

[0009] In addition, the rotation angle depends on the motor step control, no buffer and tension adjustment mechanism, long-term use of gear wear caused by stop deviation.

[0010] Therefore, the intelligent goods cabinet with fast switching of multiple types of access ports is proposed to solve the above problems. SUMMARY

[0020] A goods taking mechanism is arranged in the interior of the cabinet body, which is used to perform the goods storage and taking operation when the access warehouse is aligned with the access port.

[0021] Further, the switching mechanism comprises:

[0022] A sprocket transmission assembly is composed of at least one pair of driven sprocket and driving sprocket and chain around them;

[0023] A driving motor is connected to the driving sprocket to provide power.

[0024] a plurality of installation bars fixed on the chain for installing different groups of access bins.

[0025] Further, the alignment control mechanism comprises:

[0026] a gas pressure buffering assembly composed of a gas pipe, a first piston rod and a second piston rod, for converting the downward impact force of the access bin into a gas pressure adjusting force;

[0027] a chain tension adjusting assembly composed of a tensioning wheel driven by the second piston rod, for dynamically adjusting the tension of the chain according to the downward speed of the access bin;

[0028] a limiting assembly composed of a mounting table, a limiting plate and a first spring, for buffering and accurately positioning the downward movement of the access bin.

[0029] Further, the gas pressure buffering assembly further comprises:

[0030] a branch pipe connected to the gas pipe;

[0031] a third piston rod slidably arranged in the branch pipe;

[0032] a push block connected to the end of the third piston rod, for converting the gas pressure into a mechanical pushing force.

[0033] Further, the buffering mechanism comprises:

[0034] a guiding assembly composed of a fixing rod and a guiding block, for guiding the vertical movement of the access bin;

[0035] a pre-pressing spring assembly composed of a side plate and a second spring, for absorbing the lateral impact force in a pre-compressed state;

[0036] a pressure converting assembly composed of a push block, a pressing plate and a third spring, for converting the gas pressure buffering force into a pre-pressing force on the pre-pressing spring assembly.

[0037] Further, it further comprises:

[0038] a vertical frame fixed inside the cabinet for providing vertical movement guiding for the access bin;

[0039] an electric telescopic rod arranged inside the cabinet for selectively controlling the rotating state of the limiting plate;

[0040] a pressing block connected to the end of the piston rod of the electric telescopic rod for driving the limiting plate to rotate.

[0041] Further, the access bin comprises:

[0043] The refrigerated storage bin is configured to maintain a low-temperature environment.

[0044] The special environment storage bin is configured to maintain a specific temperature and humidity environment.

[0045] Further, the goods taking mechanism comprises:

[0047] The goods transfer device is used for transferring the goods tray between the access bin and the goods shelf.

[0048] Further, the cabinet body further comprises:

[0049] The sealing door is arranged at the access opening and is used for maintaining the sealing property of the internal environment of the cabinet body.

[0050] The environment control system is used for maintaining specific storage environment parameters in the cabinet body.

[0051] Advantages

[0052] Compared with the prior art, the technical scheme provided by the application has the following advantages:

[0053] The alignment control mechanism designed by the application comprises a gas pressure buffering assembly and a chain tension adjusting assembly, so that the accurate positioning and alignment of the access bin and the access opening can be ensured. When the access bin is lowered, the first piston rod and the gas pipe convert the impact force into gas pressure, push the second piston rod to adjust the position of the tensioning wheel, dynamically adjust the chain tension, and effectively solve the problem of inaccurate alignment of the traditional intelligent cabinet caused by chain wear.

[0054] In particular, the buffering mechanism effectively absorbs the lateral impact force generated during the movement of the access bin through the synergistic effect of the pre-pressing spring assembly and the pressure conversion assembly, avoids the torsional effect of the internal structure of the cabinet body, and ensures the smooth lifting of the access bin on the vertical frame.

[0055] In addition, the gas pressure buffering assembly in the alignment control mechanism can convert the impact force of the lowered access bin into pre-tension adjustment of the chain, avoid the sudden stop of the chain tension in the traditional design, significantly reduce the wear of the chain and the sprocket, and prolong the service life of the transmission system. Through the double buffering design of the first spring and the second spring, the impact energy of the access bin during positioning is effectively absorbed, the internal mechanical structure of the cabinet body is protected, and the maintenance requirement and the failure rate are reduced.

[0056] The alignment control mechanism converts the kinetic energy of the descending access bin into pneumatic energy, and is used for chain tension adjustment and pre-pressing of the buffer mechanism, so that energy is effectively recycled and the overall energy consumption of the system is reduced. The modular design enables independent maintenance or replacement of components (such as access bins and buffer mechanisms), thereby reducing maintenance workload and downtime and lowering operating costs.

[0057] The scheme sets multiple groups of access bins, each of which can be configured as different storage environments (such as normal temperature, refrigeration, special environment, etc.), and quickly switches through a switching mechanism to meet the differentiated needs of different types of goods (such as food, medicine, electronic products, etc.) for storage environments.

[0071] The application will be further described below in conjunction with the embodiments.

[0072] Embodiments:

[0073] Please refer to the accompanying Figures 1-7 The present application provides a multi-type access port fast switching intelligent cabinet. Two columns of vertically distributed shelves 2 are arranged in the interior of the cabinet body 1 for storing goods pallets. The cabinet body 1 is composed of a pipe frame structure and a plate material, so that the shelves 2 are in a sealed environment inside the cabinet body 1, thereby effectively blocking dust, dirt and other external pollutants from entering, thereby protecting the cleanliness and integrity of the goods, especially in industries such as food, medicine and electronic components that have higher requirements for the environment. At the same time, the sealed space can more effectively work with the temperature control and dehumidification system to provide a constant storage environment to ensure that sensitive goods remain in the best condition. The surface of the cabinet body 1 is provided with an access port 8 for accessing goods in the cabinet body 1. Meanwhile, a goods taking mechanism 3 is arranged between the two groups of shelves 2 in the interior of the cabinet body 1. The goods taking mechanism 3 includes a lifting device and a goods taking device. The lifting device is used to drive the goods taking device to vertically lift between the two columns of shelves 2. When the goods taking device moves to the access port 8, the goods pallet placed at the access port 8 can be transferred to the top of the goods taking device, and then the goods pallet is moved to different heights on the shelves 2 on both sides, and the goods pallet is transferred to the shelves 2 again, realizing the storage of goods in the cabinet body 1. An electric door is installed on the inside of the access port 8 for controlling the sealing of the cabinet body 1.

[0074] Specifically, a plurality of access warehouses 5 are arranged on the inside of the access port 8 in the interior of the cabinet body 1. Each access warehouse 5 corresponds to the access of a different type of goods. The plurality of access warehouses 5 are arranged in an up-down distribution on the switching mechanism 4. The switching mechanism 4 can drive the plurality of access warehouses 5 to lift up and down in the cabinet body 1, thereby switching the height of each group of access warehouses 5. When any access warehouse 5 is aligned with the access port 8, the transfer of the goods pallet by the goods taking mechanism 3 needs to pass through the access warehouse 5 to enter the interior of the cabinet body 1 or be taken out from the access port 8. Thus, different types of goods are in appropriate storage conditions during the access process, ensuring the safety of the goods.

[0075] More specifically, the switching mechanism 4 includes a driven sprocket 401 and a driving sprocket 402 rotatably connected inside the cabinet body 1, and a chain 403 sleeved on the driven sprocket 401 and the driving sprocket 402. The switching mechanism 4 also includes a driving motor 405 installed inside the cabinet body 1, and the output shaft of the driving motor 405 is in transmission connection with the driving sprocket 402. When the driving motor 405 is turned on, the driven sprocket 401 and the driving sprocket 402 are driven to rotate synchronously, and the chain 403 is driven to rotate. The vertical section of the chain 403 is provided with a plurality of groups of mounting strips 404 for mounting different access compartments 5. The switching mechanism 4 is arranged in two groups inside the cabinet body 1 and is distributed on both sides of the access opening 8. The access compartments 5 are mounted on the mounting strips 404 at the same height in the two groups of switching mechanisms 4, so that the chain 403 drives the access compartments 5 to stably ascend and descend inside the cabinet body 1, thereby realizing the alignment and communication of the access compartments 5 and the access opening 8.

[0076] The difference is that the cabinet body 1 is also provided with an alignment control mechanism 6, which is arranged in two groups and located on one side of the two groups of switching mechanisms 4. When the switching mechanism 4 drives the access compartments 5 to ascend and descend inside the cabinet body 1 and align with the access opening 8, the chain 403 will be worn out after a long time of use, which will cause the meshing between the chain 403 and the driven sprocket 401 and the driving sprocket 402 to be loose, thereby causing unstable transmission and making the access compartments 5 unable to accurately align with the access opening 8, thereby hindering the user from smoothly taking the goods. By arranging the alignment control mechanism 6 on one side of the switching mechanism 4, when the access compartments 5 are descending and aligning with the access opening 8, the alignment control mechanism 6 can limit and buffer the descent of the access compartments 5, effectively absorb and disperse the impact force generated by the rapid stopping of the access compartments 5, and reduce the damage to the driven sprocket 401, the driving sprocket 402 and the chain 403. At the same time, the alignment deviation caused by inertia can be reduced, thereby improving the accuracy of the alignment of the access compartments 5 and the access opening 8. In addition, the alignment control mechanism 6 can convert the impact force of the descending access compartments 5 into pressure, and use the pressure to adjust the tension of the chain 403, so as to avoid the tension fluctuation of the chain 403 caused by the instantaneous change of the power transmission at the moment of alignment pause, that is, the dynamic tension of the chain 403 is converted into static tension, thereby causing the access compartments 5 to shake at the moment of alignment with the access opening 8, affecting the alignment accuracy; the sudden change of the tension may cause the chain 403 to be overloaded momentarily, increasing the stretching and wear of the chain 403.

[0077] Specifically, the alignment control mechanism 6 comprises an air pipe 601 installed in the cabinet body 1, the air pipe 601 is arranged in an L shape, the vertical section of the air pipe 601 is parallel to the chain 403, and the vertical section of the air pipe 601 is internally provided with a first piston rod 602. When the access bin 5 is lowered, the impact force of the lowering acts on the first piston rod 602, further pushing the first piston rod 602 to extrude the gas in the air pipe 601. The horizontal section of the air pipe 601 is internally provided with a second piston rod 611, the other end of the second piston rod 611 penetrates to the outside of the air pipe 601 and is connected with the second piston rod 611, and the second piston rod 611 is matchedly installed in the second sliding rail 613 arranged in the cabinet body 1. When the gas in the air pipe 601 is extruded by the first piston rod 602, the second piston rod 611 is pushed to slide outward in the air pipe 601, further pushing the second sliding block 612 to slide horizontally in the second sliding rail 613. The second sliding rail 613 is rotationally connected with a tensioning wheel 614, the tensioning wheel 614 is meshed with the chain 403, and the tensioning wheel 614 and the driven sprocket 401 are horizontally distributed. When the tensioning wheel 614 is not affected by the displacement of the second sliding block 612, the tensioning wheel 614, the driven sprocket 401 and the driving sprocket 402 jointly tension the chain 403, so as to ensure the stability of the lifting control of the switching mechanism 4 on the access bin 5. In the process of buffering the lowering of the access bin 5, when the impact force of the lowering of the access bin 5 is converted into pressure to push the second sliding block 612 to slide, the tensioning wheel 614 is driven to move away from the side of the driven sprocket 401, so that the tensioning wheel 614 applies a certain pre-tension to the chain 403, that is, the tension is increased and adjusted, so as to offset the possible dynamic load in the future, so that the chain 403 is more stable at the moment when the access bin 5 and the access port 8 are aligned, avoids the sudden stop of the tension, reduces the amplitude of the sudden change of the tension, and reduces the impact on the chain 403; so that the switching mechanism 4 can always keep the alignment accuracy of the access bin 5 and the access port 8 during a long time of operation.

[0078] More specifically, the upper end of the first piston rod 602 is connected with a mounting table 603, and the mounting table 603 is rotationally connected with a limiting plate 605 through a torsion spring shaft 604. When the torsion spring shaft 604 is not affected by external force, the torsion spring shaft 604 always controls the limiting plate 605 to rotate towards the side of the access bin 5, so that the limiting plate 605 is rotated to a horizontal state on the mounting table 603 and is limited and blocked by the mounting table 603, and remains in the horizontal state. At this time, the limiting plate 605 protrudes between the two groups of switching mechanisms 4, further limiting and blocking the access bin 5 in the process of lowering. When the access bin 5 touches the upper surface of the limiting plate 605 in the process of lowering, the access bin 5 continuously lowers, pushes the limiting plate 605 to slide downward, further extrudes the first piston rod 602 downward through the mounting table 603, inserts the first piston rod 602 into the air pipe 601 and extrudes the gas in the air pipe 601, so as to realize the pre-adjustment and increase of the tension of the chain 403.

[0079] At the same time, the first sliding block 606 is connected to the installation platform 603, and the first sliding block 606 is adapted to slide in the first sliding rail 607 fixed in the cabinet 1. The first sliding rail 607 is internally connected to the limiting rod 608, and the first sliding block 606 is sleeved on the surface of the limiting rod 608. When the installation platform 603 slides downward under the impact force of the access bin 5, the first sliding block 606 slides downward in the first sliding rail 607. The surface of the limiting rod 608 is sleeved with the first spring 609 below the first sliding block 606. When the first sliding block 606 slides downward on the limiting rod 608, the first spring 609 is extruded, and the impact force of the downward access bin 5 can be further buffered through the first spring 609, thereby reducing the impact force generated at the moment of alignment between the access bin 5 and the access port 8, and further reducing the impact load on the chain 403 at the moment of alignment, thereby protecting the mechanical structure and ensuring that the switching mechanism 4 can stably control the accurate alignment between the access bin 5 and the access port 8 during long-term use.

[0080] It should be noted that one end of the torsion spring shaft 604 is connected to the baffle 610, and the electric telescopic rod 9 is installed above the baffle 610 in the cabinet 1. The lower end of the piston rod of the electric telescopic rod 9 is connected to the pressing block 10. When the switching mechanism 4 aligns different access bins 5 and access ports 8, the upper access bin 5 needs to be buffered by the alignment control mechanism 6 during the process of descending and aligning with the access port 8; the electric telescopic rod 9 is started, the electric telescopic rod 9 drives the pressing block 10 to slide downward and abuts against the upper surface of the baffle 610. During the process of continuously pressing the pressing block 10, the baffle 610 is pushed to rotate and overcome the elastic force of the torsion spring in the torsion spring shaft 604, thereby driving the torsion spring shaft 604 and the limiting plate 605 connected thereto to rotate synchronously, so that the limiting plate 605 rotates from the horizontal state to the vertical state on the installation platform 603. Thus, the lower access bin 5 can pass through the alignment control mechanism 6. At this time, the pressing block 10 is driven to reset by the electric telescopic rod 9. When the baffle 610 is not pushed downward by the pressure of the pressing block 10, it will reset under the elastic force of the torsion spring in the torsion spring shaft 604. The limiting plate 605 will also reset under the action of the torsion spring in the torsion spring shaft 604, thereby realizing the buffering of the alignment control mechanism 6 for the upper access bin 5.

[0081] It is worth noting that the two sides of each group of access compartments 5 are provided with buffer mechanisms 7, the inside of the cabinet body 1 is provided with vertical frames 11 on both sides of the access opening 8, and the two groups of access compartments 5 are respectively sleeved on the two groups of vertical frames 11. When the switching mechanism 4 drives the access compartment 5 to ascend and descend in the cabinet body 1, the vertical frame 11 plays a guiding role on the access compartment 5, thereby ensuring that the ascending and descending of the access compartment 5 is more stable. However, when the alignment control mechanism 6 buffers the impact force of the descending access compartment 5, the chain 403 will produce a transverse impact force due to the change of the load received by the access compartment 5 in an instant, and the impact force will be transmitted to the vertical frame 11 through the access compartment 5, causing a torsion effect, especially in the case of uneven load on the access compartment 5, thereby affecting the subsequent ascending and descending stability and alignment accuracy of the access compartment 5. The buffer mechanism 7 can convert the horizontal impact force received by the access compartment 5 into a pre-pressing force, thereby reducing the horizontal impact amplitude of the access compartment 5 on the vertical frame 11 and ensuring the sliding stability of the access compartment 5 on the vertical frame 11.

[0082] Specifically, the buffer mechanism 7 includes a fixed rod 701 installed on the side of the access compartment 5, the surface of the fixed rod 701 is sleeved with a guide block 702, and the guide block 702 is further sleeved on the surface of the vertical frame 11. When the access compartment 5 ascends and descends in the cabinet body 1, the guide block 702 will slide up and down on the surface of the vertical frame 11, and further through the guiding effect of the access opening 8 and the guide block 702, the effective alignment of the access compartment 5 with the access opening 8 during the ascending and descending process can be ensured.

[0083] The air pipe 601 is also connected with a branch pipe 615, the branch pipe 615 and the horizontal section of the air pipe 601 are in parallel distribution, and the branch pipe 615 is towards the side of the alignment control mechanism 6. The third piston rod 616 is inserted into the inside of the branch pipe 615, and the buffer mechanism 7 comprises a push block 708 installed at the outer end of the third piston rod 616. When the downward impact force of the access compartment 5 acts on the first piston rod 602, the first piston rod 602 will extrude the gas in the air pipe 601, further push the third piston rod 616 and the second piston rod 611 to slide outwards in the air pipe 601 at the same time. The slidable distance of the second piston rod 611 in the air pipe 601 is less than that of the third piston rod 616, so that when the second piston rod 611 slides to the maximum distance, the tension pulley 614 just sets the pre-tension on the chain 403, so as to ensure that the chain 403 can effectively and safely cope with the dynamic load change. At this time, the third piston rod 616 continues to slide outwards, further pushing the push block 708 to slide outwards. The buffer mechanism 7 further comprises a supporting rod 705 connected to the inner wall of the cabinet 1, and the surface of the supporting rod 705 is connected with a pressing plate 706 through a third spring 707; the pressing plate 706 is provided in a groove shape, and the two sides of the groove are provided in a slope shape which opens outwards from the inside; the groove part of the pressing plate 706 is towards the side of the access compartment 5, and when the pressing plate 706 is not affected by external force, it is always pulled away from the access compartment 5 under the elastic force of the third spring 707. The surface of the fixed rod 701 is also sleeved with two groups of side plates 703, the two groups of side plates 703 are located on the two sides of the guide block 702, and the second spring 704 is arranged between the two groups of side plates 703 and the guide block 702. When the impact force of the alignment control mechanism 6 on the access compartment 5 is buffered, and the push block 708 is pushed to slide outwards by the air pressure, the push block 708 will abut against the outer surface of the slope of the pressing plate 706, and in the process of continuous sliding of the push block 708, the push block 708 will push the pressing plate 706 to slide on the supporting rod 705, and slide towards the side of the access compartment 5 against the elastic force of the third spring 707. Further, the slope of the pressing plate 706 will abut against the outside of the side plate 703, and push the two groups of pressing plates 706 to slide towards the guide block 702, and compress the second spring 704 in the process of sliding. In the above process, the access compartment 5 is also continuously descending and not paused. When the transverse impact force acts on the access compartment 5 after the access compartment 5 completely pauses, the guide block 702 will slide transversely on the surface of the fixed rod 701, and at this time, the elastic force of the second spring 704 can buffer the sliding amplitude of the access compartment 5.And the two groups of second springs 704 are pre-compressed by the pressing plate 706, so that the second springs 704 are in a certain compression state in the rest state, thereby increasing the stiffness, and when the access bin 5 is affected by the lateral impact force, the impact energy can be converted and absorbed more quickly, reducing the impact of the sudden impact on the access bin 5; and when the access bin 5 is impacted, the stored energy can be quickly released to buffer the lateral impact force, and react with smaller displacement, avoiding the transmission of sudden high-amplitude force, thereby achieving a more stable dynamic response.
