Description

Technical Field

[0001] This invention relates to an automated warehouse, and more particularly to an intelligent storage and retrieval automated warehouse. Background Technology

[0002] Vertical storage systems, as a core component of modern enterprises and logistics centers, have been widely adopted due to their ability to fully utilize vertical space and significantly improve storage capacity and space utilization. A typical vertical storage system, in conjunction with automated guided vehicles (AGVs) or stacker cranes, allows goods to be automatically stored and retrieved by moving between racks and aisles.

[0003] However, existing vertical warehousing technology still has many shortcomings that urgently need to be addressed. First, its core transport trolley structure is usually extremely complex, integrating multiple modules such as walking, lifting, fork extension and retraction, and precise navigation and positioning. This complexity leads to high equipment manufacturing costs, and under long-term, high-frequency operation, its drive, transmission, and control systems have a high failure rate, increasing maintenance costs and downtime risks, thus affecting the stability and efficiency of the entire warehousing system.

[0004] Secondly, although some manufacturing enterprises have adopted fixed robotic arms for material storage and retrieval in their workshops, they lack flexible counting capabilities and cannot adapt to the actual needs of "on-demand, arbitrary quantity" storage and retrieval of parts during equipment production or assembly. Their lack of flexibility limits the refinement and flexibility of the production process.

[0005] In addition, existing warehouses generally lack humidity control functions, which can easily cause oxidation, rust, and mold growth on stored parts, seriously affecting the quality, precision, and service life of materials and causing unnecessary economic losses to enterprises.

[0006] Therefore, there is an urgent need in this field for a new type of warehousing solution that can overcome the above-mentioned defects, has the characteristics of simple structure, low cost and reliable operation, and can realize flexible and quantity-based storage and retrieval of materials, so as to comprehensively improve the intelligence level of the warehousing system. Summary of the Invention

[0007] To address the shortcomings of existing technologies, this invention provides an intelligent storage and retrieval automated warehouse that enables the overall storage or retrieval of parts in a pallet. It features a compact and simple structure and stable operation.

[0008] To address the aforementioned technical problems, this invention provides an intelligent storage and retrieval automated warehouse, comprising shelves, a lifting platform, and an inbound / outbound platform. The shelves include uprights and support plates at different heights on the uprights. The lifting platform includes a lifting drive mechanism and a pallet translation mechanism. The lifting drive mechanism drives the pallet translation mechanism to lift and lower, and the pallet translation mechanism drives the pallet to translate. The pallet translation mechanism includes a main frame, a translation motor, a first synchronous belt group, a second synchronous belt group, and a toggle finger. The first and second synchronous belt groups have identical structures, each including a first and second guide wheel at the upper ends, a third and fourth guide wheel at the lower ends, and a drive wheel between the third and fourth guide wheels. The drive wheel is connected to the translation motor. The first, second, third, and fourth guide wheels and the drive wheel are surrounded by synchronous belts. The toggle finger is connected to the corresponding synchronous belt via a first connecting block and a second connecting block. The toggle finger has a toggle head at its top, which can extend into a groove at the bottom of the pallet, driving the pallet to translate via the movement of the synchronous belt.

[0009] As an improvement to the above solution, the surface of the actuating head includes a horizontal abutting plane at the top, transition arc surfaces on both sides of the horizontal abutting plane, and a vertical abutting plane vertically arranged downward from the edge of the transition arc surface.

[0010] As an improvement to the above solution, the toggle finger includes a first main body portion arranged vertically, a second main body portion formed by bending outward from the upper end of the first main body portion, and a third main body portion formed by bending outward again from the top of the second main body portion; the first connecting block is disposed on the first main body portion, the second connecting block is disposed at the connection between the second main body portion and the third main body portion, and the toggle head is disposed at the top of the third main body portion.

[0011] As an improvement to the above solution, the toggle finger is positioned between the first synchronous belt group and the second synchronous belt group, and the first synchronous belt group and the second synchronous belt group have a height difference.

[0012] As an improvement to the above solution, the main frame includes a bottom crossbeam and two top crossbeams. The bottom crossbeam has a first vertical beam and a second vertical beam. The first vertical beam is connected to the top crossbeam through a first front and rear connecting beam. The top of the second vertical beam has a second front and rear connecting beam. The first guide wheel and the second guide wheel of the first synchronous belt group are located on the side of the first front and rear connecting beam. The third guide wheel, the fourth guide wheel and the drive wheel are located on the first vertical beam. The first guide wheel and the second guide wheel of the second synchronous belt group are located on the side of the second front and rear connecting beam. The third guide wheel, the fourth guide wheel and the drive wheel are located on the second vertical beam.

[0013] As an improvement to the above solution, the lifting drive mechanism includes a vertically arranged slide rail, a pulley arranged on the main frame and cooperating with the slide rail, a lifting drive belt connected to the main frame, and a lifting power assembly for driving the lifting drive belt to rotate.

[0014] As an improvement to the above solution, the feeding and discharging platform is equipped with a lifting door assembly. The lifting door assembly includes a door panel guide strip, an upper door panel, a lower door panel, an opening and closing drive belt, and a door panel opening and closing motor. The door panel guide strip is located at the end of the feeding and discharging platform. The upper door panel and the lower door panel are located on the door panel guide strip and can move up and down along the door panel guide strip. The lower door panel is connected to the opening and closing drive belt on the side closer to the lower door panel, and the upper door panel is connected to the opening and closing drive belt on the side away from the upper door panel. The door panel opening and closing motor is used to drive the opening and closing drive belt to rotate.

[0015] As an improvement to the above solution, a weighing sensor is provided at the bottom of the feeding and discharging platform.

[0016] As an improvement to the above solution, a humidity controller is provided below the loading / unloading platform, and the area below the loading / unloading platform is connected to the shelf; the humidity controller is used to control the humidity of the shelf.

[0017] As an improvement to the above solution, the shelf includes a first shelf located behind the lifting platform and a second shelf located in front of the lifting platform; the bottom of the tray is provided with a groove for engaging with the finger.

[0018] Implementing the embodiments of the present invention has the following beneficial effects: Using the above solution, the pallet translation mechanism can be driven by the lifting drive mechanism to reach the support plate at different heights. By inserting a finger into the bottom of the pallet, the pallet can be translated, and the pallet can be sent from the loading / unloading platform to the support plate or taken out from the support plate to the loading / unloading platform. This realizes the overall storage or retrieval of parts in the pallet. The structure is compact and simple, and the operation is stable.

[0019] By pre-inputting the weight parameters of the parts on each pallet, the system can calculate the number of parts put in or taken out when workers or robotic arms put in or take out parts from the pallets. This enables real-time statistics and error correction of the number of parts on each pallet on the shelf, eliminating the need for additional identification methods such as pre-attaching QR codes to the parts and saving on inbound and outbound processes.

[0020] Placing the humidity controller below the loading / unloading platform makes full use of the space below the platform. Moreover, when the humidity controller is working, the temperature and humidity around it fluctuate greatly. Placing the humidity controller below the loading / unloading platform keeps it as far away from the shelves as possible, ensuring stable humidity and temperature in the shelf area.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the directional terms such as up, down, left, right, front, back, inside, and outside used in this text are based solely on the accompanying drawings and are not intended to specifically limit the invention.

[0023] like Figures 1-8As shown, this embodiment of the invention provides an intelligent storage and retrieval automated warehouse, including a rack 1, a lifting platform 2, and an inbound / outbound platform 3. The rack 1 includes uprights 11 and support plates 12 at different heights on the uprights 11. The lifting platform 2 includes a lifting drive mechanism 4 and a pallet translation mechanism 5. The lifting drive mechanism 4 drives the pallet translation mechanism 5 to lift and lower, and the pallet translation mechanism 5 drives the pallet to translate. The pallet translation mechanism 5 includes a main frame 51, a translation motor 52, a first synchronous belt group 53, a second synchronous belt group 54, and a toggle finger 55. The first synchronous belt group 53 and the second synchronous belt group 54 have the same structure, both including a first guide wheel 531 and a second guide wheel located at the upper ends. 532. The third guide wheel 533 and the fourth guide wheel 534 located at the lower part, and the drive wheel 535 located between the third guide wheel 533 and the fourth guide wheel 534. The drive wheel 535 is connected to the translation motor 52. The first guide wheel 531, the second guide wheel 532, the third guide wheel 533, the fourth guide wheel 534 and the drive wheel 535 are provided with a synchronous belt 536 surrounding them. The toggle finger 55 is connected to the corresponding synchronous belt through its own first connecting block 551 and second connecting block 552 respectively. The top of the toggle finger 55 has a toggle head 56. The toggle head 56 can extend into the groove 101 at the bottom of the tray 100 and drive the tray 100 to translate by the movement of the synchronous belt.

[0024] Using the above solution, the lifting drive mechanism 4 can drive the pallet translation mechanism 5 to reach the support plate 12 at different heights. By using the toggle finger 55 to reach the bottom of the pallet 100, the pallet 100 can be translated, and the pallet 100 can be sent from the loading / unloading platform 3 to the support plate 12 or taken out from the support plate 12 to the loading / unloading platform 3, so as to realize the overall storage or removal of parts in the pallet. The structure is compact and simple, and the operation is stable.

[0025] To ensure reliable and smooth contact between the finger 55 and the tray 100 during storage and retrieval, the surface of the actuating head 56 includes a horizontal abutment plane 561 at the top, transition arc surfaces 562 on both sides of the horizontal abutment plane 561, and a vertical abutment plane 563 extending downward from the edge of the transition arc surfaces 562. The shelf 1 includes a first shelf 1a located behind the lifting platform 2 and a second shelf 1b located in front of the lifting platform 2; the bottom of the tray 100 is provided with a groove 101 for engaging with the finger 55. When the finger 55 is inserted into the groove 101 of the tray 100, the transition arc surfaces 562 on both sides act as guides to ensure that the finger 55 can be inserted into the groove 101. During the movement of the tray 100 by the finger 55, the vertical abutment plane 563 contacts the side wall of the groove 101, and the horizontal abutment plane 561 contacts the bottom surface of the groove 101, preventing the tray 100 from rotating and ensuring that the tray 100 can still smoothly enter and exit the support plate 12 after carrying different numbers and types of parts.

[0026] Preferably, the actuating finger 55 includes a vertically arranged first main body 553, a second main body 554 formed by bending outward from the upper end of the first main body 553, and a third main body 555 formed by bending outward again from the top of the second main body 554; a first connecting block 551 is disposed on the first main body 553, a second connecting block 552 is disposed at the connection between the second main body 554 and the third main body 555, and the actuating head 56 is disposed at the top of the third main body 555. It should be noted that the actuating finger 55 with the above structure can concentrate the stress during advancement on the second connecting block 552, quickly transmitting the power of the second synchronous belt group 54 to the tray 100. Even if the tray 100 gets stuck, the force transmission direction of the actuating finger 55 is consistent with the extension direction of its main body, and the actuating finger 55 is not easily subjected to excessive lateral force and thus does not deflect excessively, ensuring the reliable operation of the actuating finger 55.

[0027] More preferably, the actuating finger 55 is positioned between the first synchronous belt group 53 and the second synchronous belt group 54, which have a height difference. With this arrangement, the actuating finger 55 is located between the first synchronous belt group 53 and the second synchronous belt group 54, and the first and second synchronous belt groups 53 and 54 apply force to different sides of the actuating finger 55, ensuring that the force on the actuating finger 55 is roughly balanced and prevents twisting. This arrangement also reduces the space required for the actuating finger 55 along its movement trajectory, making the device structure more compact and occupying less space.

[0028] As an improvement to the above scheme, the main frame 51 includes a bottom crossbeam 511 and two top crossbeams 512. The bottom crossbeam 511 is provided with a first vertical beam 513 and a second vertical beam 514. The first vertical beam 513 is connected to the top crossbeam 512 through a first front and rear connecting beam 515. The top of the second vertical beam 514 is provided with a second front and rear connecting beam 516. The first guide wheel 531 and the second guide wheel 532 of the first synchronous belt group 53 are provided on the side of the first front and rear connecting beam 515, and the third guide wheel 533, the fourth guide wheel 534 and the drive wheel 535 are provided on the first vertical beam 513. The first guide wheel 531 and the second guide wheel 532 of the second synchronous belt group 54 are provided on the side of the second front and rear connecting beam 516, and the third guide wheel 533, the fourth guide wheel 534 and the drive wheel 535 are provided on the second vertical beam 514. A bottom crossbeam 511 and two top crossbeams 512 form an inverted triangular structure, which is simple and easy to maintain. It provides a robust structure for the main frame 51 and avoids interference with the pallet 100 on the movement trajectory. The first guide wheel 531 and the second guide wheel 532 are directly mounted on the corresponding first front and rear connecting beams 515 or second front and rear connecting beams 516. The third guide wheel 533, the fourth guide wheel 534, and the drive wheel 535 are directly mounted on the corresponding first vertical beam 513 or second vertical beam 514. This reduces the need for additional frames, making the pallet translation mechanism 5 lighter and more stable, and reducing the energy consumption of the pallet translation mechanism 5 during daily lifting and lowering.

[0029] Accordingly, the lifting drive mechanism 4 includes a vertically arranged slide rail 41, a pulley 42 mounted on the main frame 51 and cooperating with the slide rail 41, a lifting drive belt 43 connecting the main frame 51, and a lifting power assembly 44 for driving the lifting drive belt 43 to rotate. The lifting power assembly 44 may be a reducer connected to a synchronous shaft 45, which is connected to the lifting drive belts 43 on both sides, driving the two sides of the main frame 51 to lift synchronously.

[0030] Combination Figure 9 and Figure 10As shown, in some embodiments, the loading / unloading platform 3 is equipped with a lifting door assembly 6. The lifting door assembly includes a door guide strip 61, an upper door panel 62, a lower door panel 63, an opening / closing drive belt 64, and a door opening / closing motor (not shown in the figure). The door guide strip 61 is located at the end of the loading / unloading platform 3. The upper door panel 62 and the lower door panel 63 are located on the door guide strip 61 and can move up and down along the door guide strip 61. The lower door panel 63 is connected to the opening / closing drive belt 64 on the side closest to the lower door panel 63, and the upper door panel 62 is connected to the opening / closing drive belt 64 on the side furthest from the upper door panel 62. The door opening / closing motor is used to drive the opening / closing drive belt 64 to rotate. The lifting door assembly is used to close or open the passage between the loading / unloading platform 3 and the shelf 1 through the upper door panel 62 and the lower door panel 63, which can move in opposite directions, to ensure the warehouse's daily sealing and security.

[0031] Combination Figure 11 As shown, in some embodiments, a weighing sensor 7 is provided at the bottom of the loading / unloading platform 3. The weighing sensor 7 is used to weigh the total weight of the pallets 100 on the loading / unloading platform 3. By pre-inputting the part weight parameters of each pallet 100, the number of parts put in or taken out can be calculated when a worker or robotic arm puts in or takes out parts from the pallet 100, thereby realizing real-time statistics and error correction of the number of parts on each pallet 100 on the shelf 1. There is no need for additional identification methods such as pre-attaching QR codes to the parts, saving the warehousing process. For example, if a worker needs to take out 4 bolts of a certain type, after receiving the picking instruction, the warehouse uses the lifting platform 2 to take out the pallet 100 carrying the bolts according to the pallet 100 number corresponding to the bolt in the database. After the worker takes away several bolts, the warehouse automatically calculates and records the number of bolts taken out according to the current weight of the pallet 100 and the weight of a single bolt, and then the lifting platform 2 puts the pallet 100 back into the shelf 1.

[0032] Preferably, a humidity controller 8 is provided below the loading / unloading platform 3, and the area below the loading / unloading platform 3 is connected to the shelf 1; the humidity controller 8 is used to control the humidity of the shelf 1. In order to facilitate the retrieval of parts, the loading / unloading platform 3 is set at a certain height. Placing the humidity controller 8 below the loading / unloading platform 3 can make full use of the space below the loading / unloading platform 3. Moreover, when the humidity controller 8 is working, the temperature and humidity near it fluctuate greatly. Placing the humidity controller 8 below the loading / unloading platform 3 can keep it as far away from the shelf 1 as possible, ensuring the stability of humidity and temperature in the area of ​​the shelf 1.

[0033] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications are also considered to be within the scope of protection of the present invention.
