Description

Technical Field

[0001] This invention relates to the field of logistics warehousing system technology, and more specifically to a three-dimensional warehousing system suitable for the storage and transportation of standard aviation parts. Background Technology

[0002] In recent years, with the continuous improvement of my country's scientific and technological strength and overall national power, the production capacity demand of the aviation industry has been further released. Many related production and support links urgently need to achieve corresponding development through technological upgrades. For aviation standard parts manufacturers, given the characteristics of the manufactured standard parts—including their complexity, variable output, wide range of specifications and dimensions, and long storage periods—their current warehousing and logistics management is still mainly carried out manually. In the foreseeable future, this inefficient and error-prone workpiece warehousing and logistics method will be unable to adapt to the rapid growth of enterprise production capacity, becoming a bottleneck in the production of aviation standard parts. Therefore, finding a three-dimensional automated warehousing solution that can replace manual handling and efficiently manage the produced aviation standard parts has become a crucial question for enterprises seeking to increase production capacity.

[0003] Compared to traditional automated storage and retrieval systems (AS / RS), AS / RS systems used for storing and transporting aerospace standard parts require smaller, denser storage locations and more shelving. Conventional storage and retrieval devices such as stacker cranes, shuttle cars, and automated forklifts are not well-suited to these production process requirements. Furthermore, aerospace components and assemblies have stringent dimensional tolerance and mechanical performance requirements. Accurate traceability is essential at every stage of production and use, necessitating that each component have a unique identification code and be stored and packaged independently. This results in production scheduling requirements that differ significantly from those in traditional manufacturing. Summary of the Invention

[0004] In view of this, the present invention provides an automated storage and warehousing system suitable for the individual packaging, marking and storage of small-sized aerospace standard parts. It can achieve seamless integration with the existing production process of small-sized aerospace standard parts of enterprises, effectively improve their material management level and storage density, free up manpower and improve efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automated storage and retrieval system suitable for the storage and transportation of standard aviation parts includes:

[0007] A modular shelving unit has a horizontally arranged aisle in the middle. On both sides of the aisle, there are multiple storage areas for placing multiple cargo boxes and pallets, with aviation standard parts placed inside the cargo boxes and pallets.

[0008] An entry / exit track is connected to one end of the travel channel;

[0009] A logistics railcar is mounted on the entry / exit rail and can travel along the entry / exit rail to the travel channel and can climb along the side wall of the travel channel. It is used to place the cargo pallets carried on the logistics railcar to the placement area or to remove the cargo pallets from the placement area.

[0010] As can be seen from the above technical solution, compared with the prior art, this invention discloses a three-dimensional warehousing system suitable for the storage and transportation of aviation standard parts. Operators are located at the material input end of the three-dimensional warehousing system, i.e., on the entrance side of the inlet / outlet track. They place individually packaged and marked aviation standard parts into empty cargo pallets for separate storage. Then, a logistics railcar carrying the cargo pallet travels along the inlet / outlet track to the travel channel, climbing along the side wall of the travel channel to the required placement area. Finally, the cargo pallet is placed in the placement area, completing the placement of the cargo pallet. When it is time to remove the cargo pallet from the placement area, the logistics railcar removes the cargo pallet and returns to the exit side of the inlet / outlet track along the path. Therefore, this invention addresses the technological characteristics of the production and storage of aviation industrial parts, involving a three-dimensional warehousing system suitable for the separate packaging, marking, and storage of small-sized aviation standard parts. It can achieve seamless integration with the existing small-sized aviation standard part production process of enterprises, effectively improving material management level and storage density, freeing up manpower, and increasing efficiency.

[0011] Furthermore, the modular shelving unit includes:

[0012] The central frame includes: a bottom travel track and multiple vertical racks fixedly connected to both sides of the bottom travel track. The tops of the two vertical racks located at the end points of the travel channel are each fixed with a longitudinal beam. The bottom travel track, the vertical racks, and the longitudinal beams form the travel channel. Multiple first transverse racks are horizontally arranged at intervals on both sides of the bottom travel track near the vertical racks, and multiple first steering rack assemblies are rotatably connected to them. A first steering rack assembly is provided between two adjacent first transverse racks to connect them. Transition racks are provided on both sides of the bottom travel track to connect the first steering rack assemblies and the vertical racks. The transition racks are arranged perpendicular to the first transverse racks.

[0013] The cargo box storage side rack consists of two racks, which are symmetrically arranged on the left and right sides of the central frame. Each of the two cargo box storage side racks is fixedly connected to its corresponding vertical rack on one side. The cargo box storage side rack is provided with a multi-layered placement area in a frame structure, and the vertical rack is provided on both sides of the placement area.

[0014] The logistics railcar can move along the first transverse rack, and can move onto the transition rack via the first steering rack assembly, and can climb along the vertical rack.

[0015] The beneficial effects of adopting the above technical solution are: the logistics railcar can travel in the travel channel to the area below a certain placement area through the first transverse rack, and with the assistance of the first steering rack assembly, it can complete the function of turning from the first transverse rack to the transition rack, thereby enabling the logistics railcar to climb on the vertical rack corresponding to the placement area to pick up and place the cargo box pallet.

[0016] Furthermore, multiple longitudinal racks are spaced apart on the entry and exit track. A second steering rack assembly is provided between two adjacent longitudinal racks to connect the two adjacent longitudinal racks. A second transverse rack is connected between two adjacent second steering rack assemblies. The second transverse rack is arranged perpendicular to the longitudinal racks. A third transverse rack is connected between the first steering rack assembly and the adjacent second steering rack assembly. The logistics railcar can move along the longitudinal racks and can move to the second transverse rack and the third transverse rack via the second steering rack assembly, and then move to the first transverse rack via the first steering rack assembly.

[0017] The beneficial effects of adopting the above technical solution are as follows: After a certain aviation standard part that is individually packaged and marked is placed in an empty cargo pallet, the logistics railcar moves along the longitudinal rack and, with the assistance of the second steering rack assembly, completes the function of turning from the longitudinal rack to the second transverse rack, and enters the travel channel along the second transverse rack and the third transverse rack.

[0018] Furthermore, the logistics railcar includes:

[0019] Car body;

[0020] The variable pitch traveling wheel mechanism consists of two spaced-apart wheels, which are respectively located on both sides of the bottom end face of the vehicle plate. The variable pitch traveling wheel mechanism can move on the longitudinal rack, the second steering rack assembly, the second transverse rack, the third transverse rack, the first steering rack assembly, the first transverse rack, the transition rack, and the vertical rack.

[0021] A lifting platform mechanism is mounted on the vehicle platform and located between the two variable-pitch traveling wheel mechanisms;

[0022] The telescopic forks are arranged in two spaced-apart configurations, each mounted on the lifting end of the lifting platform mechanism. They are used to place the cargo pallet mounted on the telescopic forks into the placement area or to remove the cargo pallet from the placement area.

[0023] The beneficial effects of adopting the above technical solution are as follows: Initially, the logistics railcar detects its own posture, and the variable-pitch walking wheel mechanism adjusts its pitch appropriately, allowing it to adapt to the length of the longitudinal rack. This ensures that the variable-pitch walking wheel mechanism can travel along two adjacent second transverse racks, two adjacent third transverse racks, and two adjacent first transverse racks. After the variable-pitch walking wheel mechanism climbs to the designated position, the lifting platform mechanism drives the telescopic forks to move upward. Then, the telescopic forks extend and enter the placement area. Upon reaching the placement position, the lifting platform mechanism drives the telescopic forks to descend, placing the pallet on the placement area. The telescopic forks then return to the initial position, completing one pallet placement task. The variable-pitch walking wheel mechanism then returns along the original path to the material input end, or proceeds to another placement area containing pallets, picks up the pallets from that area, and then moves to the material output end, i.e., the exit side of the in-and-out rail.

[0024] Furthermore, the variable-pitch walking wheel mechanism includes:

[0025] A linear guide pair, the top end of which is fixed to one side of the bottom end face of the vehicle plate, and two mounting sliders are slidably connected to the linear guide pair;

[0026] A bidirectional lead screw drive pair is fixed to the bottom end face of the vehicle plate, and the bidirectional lead screw drive pair is provided with two first lead screw nuts that are either far apart or close to each other.

[0027] The movable steering wheel mechanism comprises two movable steering wheel mechanisms, the top ends of which are respectively fixedly connected to the first lead screw nut, and the top ends of the two movable steering wheel mechanisms are respectively fixedly connected to the two mounting sliders. The movable steering wheel mechanism can move on the longitudinal rack, the second steering rack assembly, the second transverse rack, the third transverse rack, the first steering rack assembly, the first transverse rack, the transition rack, and the vertical rack.

[0028] The beneficial effects of adopting the above technical solution are: the two-way lead screw transmission pair can drive the two first lead screw nuts to move away from or closer to each other, thereby realizing the pitch change between the two moving steering wheel mechanisms. In addition, the setting of the linear guide pair ensures the straightness, directionality and stability of the two moving steering wheel mechanisms during the pitch change process, making the pitch change more accurate and smooth.

[0029] Furthermore, both of the aforementioned moving steering wheel mechanisms include:

[0030] The mounting top plate is fixedly connected to the first lead screw nut and the mounting slider. The bottom end of the mounting top plate is fixed with a first drive motor and two bearing seats fixed at intervals. A worm gear is rotatably connected between the two bearing seats. One end of the worm gear is fixedly connected to the output end of the first drive motor.

[0031] A rotating shaft, one end of which is rotatably connected to the bottom end of the mounting top plate, and the other end of which is fixedly mounted with a moving wheel mechanism. A fixed steering worm gear is fitted on the rotating shaft, and the steering worm gear is connected to the worm gear transmission. The moving wheel mechanism can move on the longitudinal rack, the second steering rack assembly, the second transverse rack, the third transverse rack, the first steering rack assembly, the first transverse rack, the transition rack, and the vertical rack.

[0032] Furthermore, the moving wheel mechanism includes:

[0033] L-shaped wheel plate, wherein the horizontal plate of the L-shaped wheel plate is fixedly connected to the other end of the rotating shaft;

[0034] The U-shaped motor bracket has its closed end fixed to the inner wall of the vertical plate of the L-shaped wheel plate, and its open end is equipped with a traveling wheel.

[0035] The walking motor is fixed on the U-shaped motor bracket, and the drive end of the walking motor is fixedly connected to the wheel axle of the walking wheel. The walking wheel can move on the longitudinal rack, the second steering rack assembly, the second transverse rack, the third transverse rack, the first steering rack assembly, the first transverse rack, the transition rack, and the vertical rack.

[0036] The beneficial effects of adopting the above technical solution are as follows: when the traveling wheel moves to the position of the first steering rack assembly or the second steering rack assembly and needs to turn, the first drive motor drives the worm to rotate, the worm drives the steering worm wheel to rotate, and then drives the rotating shaft to rotate, so that the traveling wheel mechanism can be rotated. Thus, during the rotation of the traveling wheel, the first steering rack assembly or the second steering rack assembly is driven to rotate, that is, the traveling wheel is turned 90 degrees, and thus the logistics railcar is turned.

[0037] Furthermore, a second lead screw nut is fixed in the middle of the vehicle platform, and multiple first vertical guide rods are evenly distributed and fixed at the top of the vehicle platform. The lifting platform mechanism includes:

[0038] The second vertical guide rod, there are multiple second vertical guide rods, one end of which is evenly distributed and fixed to the middle of the bottom end face of the vehicle board;

[0039] A lifting motor is located between a plurality of second vertical guide rods, and the mounting bracket of the lifting motor is arranged through the plurality of second vertical guide rods;

[0040] A vertical lead screw, which is threadedly connected to the second lead screw nut, and one end of the vertical lead screw is fixedly connected to the drive end of the lifting motor;

[0041] The lifting platform is the lifting end, which is located above the vehicle platform. A fixed bearing passes through the middle of the lifting platform, and the other end of the vertical lead screw passes through the bearing. Multiple linear bearings are evenly distributed on the lifting platform, and the first vertical guide rod passes through the linear bearing. Both telescopic forks are set on the top surface of the lifting platform.

[0042] The beneficial effects of adopting the above technical solution are as follows: During lifting, the lifting motor drives the vertical lead screw to rotate. Under the action of the second lead screw nut, the vertical lead screw moves up and down, thereby causing the lifting platform and the lifting motor to move up and down, ultimately realizing the lifting forks' up and down movement. Furthermore, the second vertical guide rod ensures the linearity and stability of the lifting motor's up and down movement, and the first vertical guide rod ensures the linearity and stability of the lifting platform's up and down movement.

[0043] Furthermore, the cargo pallet is provided with slots, and both of the telescopic forks include:

[0044] The lower slide rail has its bottom end fixed to one side of the top of the lifting platform, and a lower mounting slider is slidably connected to the lower slide rail.

[0045] An intermediate telescopic plate, the bottom end of which is fixedly connected to the lower mounting slider;

[0046] The upper slide rail has its bottom end fixedly connected to the top end of the middle telescopic plate, and an upper mounting slider is slidably connected to the upper slide rail.

[0047] An upper telescopic plate, the bottom end of which is fixedly connected to the upper mounting slider, and an upper rack is fixed to one side of the bottom end of the upper telescopic plate. The upper telescopic plate can be inserted into the slot.

[0048] The lower rack is fixed to the top surface of the lifting platform and located on one side of the lower slide rail, and directly below the upper rack.

[0049] The second drive motor is fixedly connected to one side of the intermediate telescopic plate via a connecting frame. The drive end of the second drive motor is fixed with a transmission gear, which meshes with the lower rack and the upper rack for transmission.

[0050] The beneficial effects of adopting the above technical solution are as follows: the second drive motor drives the transmission gear to rotate. Since the transmission gear meshes with the lower rack and the upper rack, the middle telescopic plate can slide along the length of the lower slide rail, and the upper telescopic plate on the middle telescopic plate can slide along the length of the upper slide rail. Therefore, the upper telescopic plate can extend and retract at twice the speed, improving the extension and retraction efficiency of the forks, thereby improving the placement and retrieval efficiency of the cargo box, and greatly improving the storage efficiency of materials.

[0051] Furthermore, the top of the vehicle platform is fixed with handling handles on both outer sides of the lifting platform.

[0052] The beneficial effects of adopting the above technical solution are: it facilitates the handling and loading / unloading operations of logistics railcars. Attached Figure Description

[0116] For logistics railcar 4, C x The value should be slightly less than the T value of the cargo box pallet 2. x 'Value; C z The value is a floating value, which depends on the superposition of the external dimensions of components such as the lifting platform 435, intermediate telescopic plate 442, upper telescopic plate 444, transmission gear 449, lower rack 446, upper rack 445, lower slide rail 441, and upper slide rail 443 in the height direction, and on the real-time movement stroke of the lifting platform mechanism 43. The values ​​from both aspects are multiplied by a correction factor ac. z '、bc z Then add them together to get C at the corresponding time. z Actual value; C x Value and C y The value depends on the external dimensions of the vehicle platform 41, which in turn depends on the T of the cargo box pallet 2. x Value and T y The value is the primary basis; C z The value is also a floating value, which depends on the superposition of the external dimensions of components such as the car body 41, linear guide pair 421, bidirectional lead screw transmission pair 422, and moving steering wheel mechanism 423 in the height direction, and also on C. z The magnitude of the value is determined by multiplying both values ​​by the correction factor ac. z bc z Then add them together to get C at the corresponding time. z Actual value; P x The value depends on C x The values ​​and external dimensions of components such as the bidirectional lead screw drive pair 422 and the moving steering wheel mechanism 423; P y The value is also a floating value, which depends on C. y The values ​​and external dimensions of components such as the moving steering wheel mechanism 423 depend on the real-time travel of the bidirectional lead screw drive pair 422.

Figure 15 As shown, where L x L represents the center-to-center distance between the paired longitudinal racks 31; y This represents the center-to-center distance between the paired second steering rack assemblies 32, and also the center-to-center distance between the paired first lateral racks 1111; L z J represents the height of the outriggers on the track; x This represents the lateral center distance between two adjacent sets of vertical racks 112 located on the same side, and also the lateral center distance between two adjacent sets of first steering rack assemblies 1112 located on the same side, as well as the length of the placement area 1201; J y J represents the spacing between two vertical racks 112 arranged opposite each other; z J represents the height of the shelving beams on the first floor from the ground; y 'Represents the width of placement area 1201; J z 'Represents the height of placement area 1201.

[0118] Specifically, L enters and exits orbit 3 x The value should be consistent with the P value of logistics railcar 4. x The values ​​should be equal, and should also be consistent with J of modular shelving 1. x The values ​​are equal; L enters and exits orbit 3 y The value should be greater than P of logistics railcar 4. y The minimum value P in floating values ymin And a certain margin ΔP is reserved. ymin At the same time, it should be less than J y Value; J for entering and exiting orbit 3 y The value should be less than P of logistics railcar 4. y Maximum value P in floating values ymax And a certain margin ΔP is reserved. ymax L z The value should ensure that, while guaranteeing the installation process of the inlet / outlet rails 3 and all components of the modular shelving 1, the upper surfaces of each rack are flush with each other; the J of the modular shelving 1 z The value depends primarily on three values, namely L z Value, logistics railcar 4 of C z The minimum value C in floating values zmin And the T of the cargo box pallet 2 z The value is calculated by adding the first two values ​​together, subtracting the third value, and then multiplying this value by a correction factor greater than 1 (aj). z J can then be obtained z Value; J of modular shelving 1 yThe value should be on pallet 2 of the cargo box. y A certain margin ΔT is left on the basis of the value. y ; J of modular shelving 1 z The value should primarily refer to B of pallet 2. z Value, T z The value and the necessary margin ΔJ when the logistics railcar 4 places the pallet 2 on the modular rack 1. z 'Value, will B z Value, T z Value, ΔJ z The values ​​are summed and multiplied by a correction factor greater than 1, bj z ', then J can be obtained z 'value.

[0119] The basic workflow of the automated storage and warehousing system for storing and transporting standard parts for the aerospace industry, which is involved in this invention, is as follows:

[0120] (1) The operator is located at the material input end of the automated storage system (the material input end is on one side of the inlet and outlet track, and the material output end is on the other side). The operator places a certain aviation standard part that is individually packaged and marked into an empty cargo pallet 2 for separate storage. At the same time, the operator updates the QR code and RFID tag of the cargo pallet 2 and enters the relevant production process information into the electrical control subsystem of the automated storage system.

[0121] (2) The electrical control subsystem of the automated storage system will configure a designated modular rack 1 for the cargo pallet 2 according to the storage and transportation classification rules and numbering standards established in advance by the factory, and plan the travel route on the longitudinal rack 31 for the standby logistics railcar 4, determine the position of the second steering rack assembly 32 and the second transverse rack 33 that are connected to it, and calculate the lateral movement distance on the matching first transverse rack 1111 and the climbing height on the vertical rack 112 and other relevant information.

[0122] (3) The standby logistics railcar 4 completes wireless communication with the electrical control subsystem of the automated storage system by identifying the QR code and RFID tag on the cargo pallet 2, and obtains information such as the driving route, lateral distance, and climbing height specified by the electrical control subsystem of the automated storage system in step (2).

[0123] (4) When the operator issues commands on the human-machine interface, the logistics railcar 4 detects its own posture. This mainly involves two aspects: firstly, controlling the operation of the four first drive motors 4232 and the worm gear and steering worm wheel to ensure that the rotation axis of the four traveling wheels 42363 is perpendicular to the longitudinal rack 31; secondly, controlling the operation of the variable pitch motors (not shown) of the two bidirectional screw drive pairs 422 to ensure the P of the logistics railcar 4. y Floating values ​​and L y The values ​​are equal.

[0124] (5) After self-inspection, the logistics railcar 4, carrying a cargo pallet 2 containing aviation standard parts, starts from the material input end according to the planned travel route. It controls four walking motors 42364 to drive the corresponding walking wheels 42363 to rotate along the longitudinal rack 31 to the four second steering rack assemblies 32 that are connected to it, and stops on the axis of rotation of the corresponding second steering rack assembly 32. At this time, the corresponding sensors can obtain the real-time position of the logistics railcar 4 and upload it to the electrical control subsystem of the automated storage and retrieval system. After updating the relevant data, the four first drive motors 4232 and the worm gear and steering worm wheel of the logistics railcar 4 start to operate, driving the corresponding walking wheels 42363 and the connected second steering rack assembly 32 to rotate until the rotation axis of the four walking wheels 42363 is parallel to the longitudinal rack 31 and perpendicular to the second transverse rack 33.

[0125] (6) Afterwards, the logistics railcar 4 continues to control the four traveling motors 42364 to drive the corresponding traveling wheels 42363 to rotate, travel along the second transverse rack 33, pass through the first transverse rack 1111 to reach the four first steering rack assemblies 1112 that are connected to it, and stop on the axis of rotation of the corresponding first steering rack assembly 1112. At this time, the corresponding sensors can obtain the real-time position of the logistics railcar 4 and upload it to the electrical control subsystem of the automated storage and retrieval system. After updating the relevant data, the four first drive motors 4232 and the worm gear and steering worm wheel of the logistics railcar 4 operate again, driving the corresponding traveling wheels 42363 together with the connected first steering rack assembly 1112 to rotate until the rotation axis of the four traveling wheels 42363 is parallel to the first transverse rack 1111 and perpendicular to the transition rack 1113.

[0126] (7) After attitude adjustment, the logistics railcar 4 controls the operation of two bidirectional screw drive pairs of variable pitch motors (not shown), which will move the P of the logistics railcar 4. y The floating value is corrected to match the J value of the vertical rack 112. y When the values ​​are equal, the logistics railcar 4 will upload its motion status information to the electrical control subsystem of the automated storage and retrieval system. After updating the relevant data, the four walking motors 42364 of the logistics railcar 4 will drive the corresponding walking wheels 42363 to rotate. While holding the cargo pallet 2 containing aviation standard parts, the logistics railcar 4 will climb upwards to the designated height along the vertical rack 112.

[0127] (8) Once the logistics railcar 4 climbs to the designated height and reaches the designated shelf layer's placement area, the corresponding sensors acquire the real-time position of the logistics railcar 4 and upload it to the electrical control subsystem of the automated storage and retrieval system. After updating the relevant data, the logistics railcar 4 controls the lifting motor 432 to operate in the forward direction, and the related C... zThe floating value will be located at its maximum value C. zmax Nearby, a ΔJ is simultaneously generated that is conducive to placing the cargo pallet 2. z At this time, the second drive motor 447 drives the transmission gear 449 to rotate in the forward direction. Under the combined action of the lower rack 446 and the upper rack 445 that mesh with the transmission gear 449, the upper telescopic plate 444 will move along with the cargo pallet 2 it holds to one side of the designated placement area until the cargo pallet 2 is located in the middle of the placement area.

[0128] (9) Finally, the logistics railcar 4 controls the lifting motor 432 to run in reverse, and the related C z The floating value will return to its minimum value C. zmin Nearby, corresponding ΔJ z The value is reset to zero, and the cargo pallet 2 is placed steadily in the designated position in the placement area. At this time, the second drive motor 447 drives the transmission gear 449 to rotate in the opposite direction. Under the combined action of the lower rack 446 and the upper rack 445 that mesh with the transmission gear 449, the upper telescopic plate 444 will return to its initial position.

[0129] (10) After completing the placement of a pallet 2, the logistics railcar 4 will upload its movement status back to the electrical control subsystem of the automated storage and retrieval system. The electrical control subsystem will, according to the production scheduling requirements, direct the logistics railcar 4 to return to the material input end where the operator is located, or it may direct the logistics railcar 4 to go directly to another location on the modular rack 1 where another pallet 2 is placed, pick up that pallet 2, and then move it to the material output end of the automated storage and retrieval system.
