Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of intelligent warehousing and logistics technology, specifically to items storage and retrieval devices. Background Technology

[0002] With the diversification of warehousing needs, the demand for high-density storage is also gradually increasing. In traditional warehousing systems, the storage and retrieval devices often adopt a design that combines guide rails and traveling columns. The guide rails are set on the shelves, and the loading platform is set on the traveling column. The traveling column moves horizontally along the guide rail, and the storage and retrieval operations of goods are realized by raising and lowering the loading platform.

[0033] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0034] Figure 1 This is a schematic diagram of the structure of an article storage and retrieval device according to some embodiments of the present disclosure. Figure 1It includes a fixed guide rail 1, a balanced support guide rail 2, a power supply device 3, a load-bearing structure 4, a transmission component 5, a moving component 6, an auxiliary moving component 7, and a moving guide rail 31.

[0035] In some embodiments, the above-mentioned article storage and retrieval device includes: a carrying and moving structure and a driving structure. The carrying and moving structure can be a device capable of providing stable movement and retrieval of articles. The articles can represent various goods that need to be stored and retrieved, and are not specifically limited herein. The driving structure can be a device capable of providing power to the carrying and moving structure, and is not specifically limited herein. The carrying and moving structure can include a guide rail structure and a carrying structure 4. The guide rail structure can be a device capable of providing guidance and support for the movement of the carrying structure 4, enabling the carrying structure 4 to move smoothly. The carrying structure 4 can be a platform for carrying and retrieving the articles.

[0036] In some embodiments, the guide rail structure may include a fixed guide rail 1 and a movable guide rail 31. The fixed guide rail 1 may be a track fixed to the crossbeam of the shelf, providing guidance and support for the movable guide rail 31, allowing the movable guide rail 31 to move smoothly along the fixed guide rail 1. The shelf may be a platform for storing the items. The movable guide rail 31 may be a rigid frame capable of moving along the fixed guide rail 1. For example, the movable guide rail 31 may be a door frame or a column, capable of moving along the length of the fixed guide rail 1. The fixed guide rail 1 may be connected to the movable guide rail 31, allowing the movable guide rail 31 to move along the fixed guide rail 1. The carrying structure 4 may be connected to the movable guide rail 31, allowing the carrying structure 4 to move along the movable guide rail 31, and also enabling the carrying structure 4 to move with the movable guide rail 31, thereby realizing the storage and retrieval operation of items. The fixed guide rail 1 mentioned above may include at least one balancing support guide rail 2. The balancing support guide rail 2 can be a track that provides support and balance for the moving guide rail 31. The balancing guide rail is connected to the moving guide rail 31, which can further distribute the load of the moving guide rail 31, reduce structural deformation or damage caused by uneven load distribution, and thus improve the service life and safety of the entire storage and retrieval device. At the same time, by increasing the number of the balancing support guide rails 2, the structural strength and stability of the storage and retrieval device can be further improved, thereby adapting to higher shelves and meeting the needs of larger storage capacity. For example, two or more balancing support guide rails 2 can be set. These balancing support guide rails 2 can be arranged in parallel to evenly distribute the load of the moving guide rail 31, thereby making the storage and retrieval device more stable and safer during operation. The number of the balancing support guide rails 2 can be flexibly configured according to actual needs. For example, in scenarios where the shelf height requirement is high, the number of balancing support guide rails 2 can be increased to improve the structural strength and stability of the storage and retrieval device, while in scenarios where the shelf height requirement is low, the number of balancing support guide rails 2 can be appropriately reduced to reduce the cost of the storage and retrieval device. The aforementioned drive structure is configured to drive the movable guide rail 31 to move along the fixed guide rail 1 and / or drive the carrying structure 4 to move along the movable guide rail 31 to store and retrieve items. For example, the drive structure can be a motor, which can be located at the connection between the movable guide rail 31 and the fixed guide rail 1 to drive the movable guide rail 31 to move along the fixed guide rail 1, or it can be located at the connection between the movable guide rail 31 and the carrying structure 4 to drive the carrying structure 4 to move along the movable guide rail 31 to complete the storage and retrieval of items. The drive structure includes a power supply device 3, which can provide electrical energy to the storage and retrieval device. For example, the power supply device 3 can be a sliding contact line, which can provide a stable power supply to the motor to ensure the normal operation of the storage and retrieval device. The power supply device 3 can be arranged parallel to the fixed guide rail 1 to ensure that the power supply device 3 can provide stable power even when the movable guide rail 31 is moving.

[0040] Optionally, the aforementioned driving structure may include a moving component 6, which can be a device capable of driving the moving guide rail 31 to move along the fixed guide rail 1. The moving component 6 may be disposed on the moving guide rail 31. The moving component 6 may include a guide plate 17 and a drive wheel 16. The guide plate 17 can be the basic frame of the moving component 6, providing rigid support for the moving component 6. The drive wheel 16 can be a device capable of providing power for the moving guide rail 31 to move along the fixed guide rail 1. For example, the drive wheel 16 can be a motor and a rotating wheel, with the rotating wheel connected to the output shaft of the motor. The drive wheel 16 can be fixed on the guide plate 17. To meet the power requirements of the moving guide rail 31, a drive wheel 16 can be provided at each end of the guide plate 17 to increase power. The fixed guide rail 1 is provided with a guide groove 24 and a fixed plate 25. The guide groove 24 can be a continuous groove provided along the length of the fixed baffle, used to provide guidance when the drive wheel 16 drives the moving guide rail 31 to move. The aforementioned fixing plate 25 can be a connector that connects to the crossbeam of the shelf. One side of the fixing plate 25 is connected to the aforementioned guide groove 24, and the other side of the fixing plate 25 is connected to the crossbeam of the shelf. This allows the fixing guide rail 1 to be fixed to the crossbeam of the shelf, increasing the structural strength of the fixing guide rail 1, enabling it to withstand greater loads, and improving the safety and service life of the entire storage and retrieval device. The aforementioned guide groove 24 is embedded in the aforementioned guide plate 17, allowing the drive wheel 16 to move smoothly along the outer surface of the guide groove 24, thereby driving the moving guide rail 31 to move along the fixed guide rail 1.

[0041] Optionally, the guide plate 17 is provided with a guide wheel assembly 22, which can be a device that increases the movement stability and smoothness of the moving component 6. The guide wheel assembly 22 includes at least two guide wheels, which can be arranged adjacent to each other at one end of the guide plate 17. The distance between the two guide wheels can be equal to the thickness of the sidewall of the guide groove 24. The sidewall of the guide groove 24 can be embedded between the guide wheels in the guide wheel assembly 22, allowing the guide wheels to roll smoothly along the sidewall of the guide groove 24. This reduces friction between the moving component 6 and the fixed guide rail 1, extends the service life of the entire access device, and increases the movement stability and smoothness of the moving component 6. To further improve the movement stability and smoothness of the moving component 6, guide wheel assemblies 22 can be provided at both ends of the guide plate 17. Specifically, refer to... Figure 5 , Figure 5 This is a schematic diagram of the connection between the movable component 6 and the fixed guide rail 1 in some embodiments of this disclosure. In the diagram, the guide plate 17 can be an inverted "T"-shaped rigid support of a certain length. Both ends of the vertical portion are provided with mounting bases for mounting the drive wheel 16, ensuring that the rotating wheel of the drive wheel 16 is parallel to the vertical portion and that the distance between the rotating wheel and the horizontal portion is equal to the height of the side wall of the guide groove 24. Guide wheel sets 22 can be provided at both ends of the horizontal and vertical portions of the guide plate 17, with each guide wheel of the guide wheel set 22 being perpendicular to the vertical portion. One side wall of the guide groove 24 of the fixed guide rail 1 is connected to the fixed plate 25, and the other side wall is embedded between the guide wheels in the guide wheel set 22, ensuring that the rotating wheel contacts the outer surface of the guide groove 24. When the rotating wheel of the drive wheel 16 rotates, it can drive the movable guide rail 31 to move. Simultaneously, the guide wheel set 22 can provide guidance for the movable guide rail 31, reducing friction and increasing the stability and smoothness of the movable component 6.

[0042] Optionally, a floating component may be provided between the moving component 6 and the moving guide rail 31. The floating component can be a device capable of reducing vibration during movement through elastic deformation, thereby improving the operational stability of the entire access device. The floating component may include a fixed block 19 and a buffer 18. The fixed block 19 can be a rigid mounting support, fixed to the moving guide rail 31. The fixed block 19 is provided with a floating shaft, which can be a vertical shaft. One end of the floating shaft is nested in the fixed block 19, and a limiting plate is provided in the middle portion of the floating shaft. The limiting plate can be a baffle perpendicular to the floating shaft, which can limit movement when the other end of the floating shaft is embedded in one end of the buffer 18. The buffer 18 can be an elastic element that can reduce the vibration energy generated by the moving guide rail 31 during movement through elastic deformation. For example, the buffer 18 can be a compression spring, capable of reducing the vibration energy generated by the moving guide rail 31 during movement through elastic deformation. The aforementioned floating shaft can be embedded in one end of the aforementioned buffer member 18. The aforementioned moving component 6 can be provided with a floating plate, which can be a horizontally arranged flat plate. The other end of the aforementioned buffer member 18 can be disposed on the aforementioned floating plate. In order to prevent the aforementioned buffer member 18 from displacing, a limiting shaft perpendicular to the floating plate can also be provided on the floating plate. The aforementioned limiting shaft can be embedded in the aforementioned buffer member 18. When the buffer member 18 undergoes elastic deformation under force, it can ensure that the buffer member 18 can be compressed and rebound along the axial direction of the buffer member 18, preventing the buffer member 18 from bending or misaligning.

[0043] Optionally, the floating component may further include a floating slider 27 and a floating guide rail 26. The floating guide rail 26 may be a track providing a movement trajectory for the floating slider 27. The floating slider 27 may be a sliding block adapted to the floating guide rail 26. The floating guide rail 26 may be connected to the moving guide rail 31. The floating slider 27 may be connected to the moving component 6. The floating slider 27 may be configured to slide along the floating guide rail 26. Specifically, the floating guide rail 26 may be fixed to the moving guide rail 31, and the floating slider 27 may be fixed to the guide plate 17. The floating guide rail 26 may have protrusions, and the floating slider 27 may have grooves adapted to the protrusions. The length of the floating guide rail 26 may be greater than the length of the floating slider 27, allowing the floating slider 27 to slide along the floating guide rail 26 through the cooperation of the protrusions and grooves. When the moving guide rail 31 vibrates, the vibration energy can be reduced by the buffer 18, and the swaying of the moving guide rail 31 can be limited by the floating slider 27 and the floating guide rail 26, which can improve the stability of the moving guide rail 31 during movement.

[0044] Optionally, the moving component 6 may be equipped with a positioning sensor 20. The fixed guide rail 1 may be equipped with a positioning hole 23. The positioning sensor 20 may be a sensor used to detect the position of the moving component 6 relative to the fixed guide rail 1. The positioning hole 23 may be a marker point or a through hole provided on the fixed guide rail 1, used to cooperate with the positioning sensor 20 to determine the accurate position of the moving component 6. The positioning sensor 20 may be fixed at the middle edge of the guide plate 17. Specifically, the positioning sensor 20 can be a mirror sensor, the mirror 21 can be close to the vertical part of the guide plate 17, the positioning sensor 20 can be set in the horizontal part corresponding to the mirror 21, and the positioning holes 23 can be evenly arranged on the side wall of the guide groove 24. When the guide groove 24 is embedded in the guide plate 17, the positioning sensor 20 can be located inside the guide groove 24, and the side wall of the guide groove 24 can be located between the mirror 21 and the positioning sensor 20. The positioning sensor 20 can detect the signal reflected by the mirror 21 through the positioning holes 23 to determine the current position of the moving guide rail 31, thereby realizing precise control of the position of the storage device.

[0045] Figure 6 This is a schematic diagram of the structure of a carrier structure according to some embodiments of this disclosure. Figure 6 It includes a first sensor group 8, a connecting plate 9, a baffle 10, a fork 11, a drive motor 12, a second sensor 13, a support frame 14, and a camera group 15.

[0046] Optionally, the aforementioned carrying structure 4 may include an identification component, a storage component, a support frame 14, and a connecting plate 9. The identification component can be a device for identifying items to be stored or retrieved, which can determine the location or type of the item by scanning and reading the identification information on the item.

The storage component can be a device capable of performing storage and retrieval operations. The support frame 14 can be a frame for supporting the storage component and the identification component, which can increase the structural strength of the carrying structure 4. The connecting plate 9 can be a component connecting the aforementioned moving guide rail 31 and the aforementioned carrying structure 4, allowing the carrying structure 4 to move with the moving guide rail 31, and also allowing the carrying structure 4 to move along the moving guide rail 31. Specifically, the connecting plate may have mounting holes, and the moving guide rail may have a slider that can move along the track direction of the moving guide rail. The slider may have threaded holes, and a screw can be passed through the mounting holes of the connecting plate and engage with the threaded holes to fix the connecting plate. At this time, when the slider moves along the moving guide rail, it can drive the carrying structure to move synchronously. The identification component may include a first sensor group 8. The first sensor in the first sensor group 8 may be a sensor for detecting whether there are obstacles around the carrying structure 4. For example, the first sensor may be a lidar or an ultrasonic sensor. By using multiple first sensors as the first sensor group 8, multiple first sensors can detect whether there are obstacles around the carrying structure 4 in real time, so as to ensure that the storage device will not collide with surrounding objects during movement, thereby improving the safety and stability of the storage device. The first sensor in the first sensor group 8 may be located on the side wall of the carrying structure 4 or the bottom of the support frame 14. It can detect whether there are obstacles on the side and bottom of the carrying structure 4. When there are obstacles, the storage and retrieval of items will stop to avoid collisions with surrounding objects. The aforementioned storage and retrieval components may include forks 11, which are configured to store and retrieve items. For example, the forks 11 may be connected to a drive motor 12, and the rotation of the drive motor 12 enables actions such as extension, clamping, etc., to remove or place items from the shelf. The aforementioned support frame 14 may be located at the bottom of the aforementioned carrying structure 4, providing rigid support for the carrying structure 4 and capable of supporting the items to be stored and retrieved.

[0047] Optionally, the fork 11 is provided with a baffle 10, which can be a structure for limiting the movement of an item. The baffle 10 can be disposed on the inner wall of the fork 11, and the baffle 10 can also rotate. For example, when the fork 11 is not storing or picking up an item, the baffle 10 can be disposed parallel to the side wall of the fork 11. When the fork 11 stores or picks up an item, the baffle 10 can be rotated to a position perpendicular to the side wall of the fork 11. The baffle 10 can be located in front of or behind the item, and the item moves with the extension and retraction of the fork 11, thereby realizing the storage and retrieval of the item.

[0048] Optionally, the aforementioned identification components may further include a second sensor 13 and a camera group 15. The second sensor 13 can be a sensor for detecting whether there are items on the support frame 14 of the carrying structure 4. For example, the second sensor 13 can be a weight sensor, which can be installed at the bottom of the support frame 14. When the carrying structure 4 carries items, it can determine whether there are items by detecting changes in weight. The camera group 15 can be a device for identifying a set of information about items to be stored. The set of information about items to be stored may include storage location information and item information. The storage location information may include the specific location of the shelf, the number of layers, and the specific storage location of each layer. The item information may include the name, specifications, quantity, production date, and shelf life of the item. The first end of the support frame 14 is connected to a camera within the camera group 15, and the second end of the support frame 14 is connected to a camera within the camera group 15. The head and tail ends of the aforementioned support frame 14 can be determined according to the extension and retraction direction of the forks 11. For example, when the forks 11 extend forward, the end of the support plate where the forks 11 extend forward can be designated as the head end, and the opposite end as the tail end. Recognition can be achieved through cameras at both ends, enabling accurate placement of items into the corresponding storage location on the shelf or retrieval of items from the corresponding storage location on the shelf.

[0049] Optionally, the aforementioned driving structure includes a conveying component 5, which can be a device for moving the carrying structure 4 along the moving guide rail 31. The conveying component 5 is disposed on the moving guide rail 31 and may include a motor, a conveyor belt, and a conveyor slider. The motor can provide power. The conveyor belt can be an annular belt for transmitting power and motion; for example, the conveyor belt can be a synchronous belt, driven by a motor to achieve movement. The conveyor slider can be a connecting block connected to the conveyor belt, transmitting the linear motion of the conveyor belt to the carrying structure 4. The conveyor belt can be connected to one end of the conveyor slider, and the other end of the conveyor slider can be connected to the connecting plate 9, allowing the carrying structure 4 to move with the movement of the conveyor slider, thus enabling the storage and retrieval of items.

[0050] Figure 7 This is a schematic diagram of the splicing surface structure of some embodiments of this disclosure. Figure 7 Includes gap 28, splicing surface 29, and fixing hole 30.

[0051] Optionally, the fixed guide rail 1 is formed by splicing at least two guide rails through a splicing surface 29. The splicing surface 29 can be a plane where two adjacent guide rails contact each other. For example, the end faces of the two guide rails can be mutually compatible end faces, with one end of one guide rail having a protrusion and the other end having a groove. The protrusion can be embedded in the groove, allowing for quick splicing of the two guide rails. Simultaneously, a fixing hole 30 is provided at the splicing point of the two guide rails, allowing for the fixing of the guide rails by inserting screws into the fixing hole 30. A gap 28 can be provided at the splicing surface 29, located at the corner of the guide groove 24, and the gap 28 can be set along the length of the guide groove 24. For example, the guide groove 24 can be a "U" shaped groove, and gaps can be set at the two corners of the "U" shaped groove. The gaps can be located at both ends of the guide rail. When the two guide rails are spliced, the gaps 28 can effectively eliminate adverse stress, prevent the edges from warping during processing, and also help improve the flatness of the subsequent guide rail splicing.

[0052] Optionally, the number of fixed guide rails 1 is at least two, and the at least two fixed guide rails 1 can be arranged in parallel, located at both ends of the movable guide rail 31. Using at least two fixed guide rails 1 increases the structural strength and stability of the storage device. For example, in scenarios requiring the storage and retrieval of heavy items, increasing the number of fixed guide rails 1 allows the storage device to withstand a greater load. Simultaneously, the parallel arrangement of the fixed guide rails 1 also improves the storage device's resistance to tipping over, increasing its safety. Movable components 6 are provided at the connection points between the movable guide rail 31 and the at least two fixed guide rails 1, ensuring that while increasing the shelf height, both ends of the movable guide rail 31 can move smoothly and synchronously, improving the overall stability and reliability of the storage device.

[0053] Optionally, the aforementioned drive structure further includes an auxiliary moving component 7, which can be a device for providing additional support force to the aforementioned moving guide rail 31. The auxiliary moving component 7 includes the aforementioned guide plate 17, the aforementioned guide wheel set 22, and passive wheels. The passive wheels can be wheels without a drive source, passively rotating only when the moving guide rail 31 moves along the fixed guide rail.

[0054] The above embodiments of this disclosure have the following beneficial effects: the item storage and retrieval device of some embodiments of this disclosure can improve the storage capacity of items. Specifically, the reason for the low storage capacity of items is that the structural strength and stability of existing storage and retrieval devices are difficult to meet the requirements of high storage density. In order to enable existing storage and retrieval devices to operate smoothly, the height of the shelves is usually low, and the length of the walking columns is usually short, resulting in low storage density and thus low storage capacity of items. Based on this, some embodiments of this disclosure provide an item storage and retrieval device, the method including: a carrying moving structure and a driving structure, wherein the carrying moving structure includes a guide rail structure and a carrying structure; the guide rail structure includes a fixed guide rail and a moving guide rail, the fixed guide rail is connected to the moving guide rail, the carrying structure is connected to the moving guide rail, wherein the fixed guide rail includes at least one balancing support guide rail; the driving structure is configured to drive the moving guide rail to move along the fixed guide rail and / or drive the carrying structure to move along the moving guide rail to store and retrieve items. By setting up balanced support rails, the number of support points for the moving rails can be increased, thereby increasing the structural strength of the entire storage and retrieval device. This allows for the increase of shelf height while meeting stability requirements, effectively improving storage density and increasing the storage capacity of items.
