Description

Technical Field

[0001] This invention relates to an automated storage and warehousing device based on the rapid turnover of automobile seats. Background Technology

[0002] Currently, due to the need to meet customer delivery deadlines when producing the same car model and seats from different suppliers, and with diversified functions, and with the rise of intelligent vehicle manufacturing and the increasing demands of automakers on suppliers, the requirements for vehicle assembly have brought about significant changes in seat delivery modes and transportation requirements. The delivery has shifted from a large quantity of complete sets of trolleys to multiple manufacturers supplying the same supplier for delivery. This means that automakers subcontract their procurement, selecting the most technologically advanced and reasonably priced suppliers to deliver different styles and grades of seats. This reduces automakers' procurement costs and enhances the competitive landscape for suppliers. This requirement necessitates that priority suppliers invest more in intelligent warehousing and ensure seamless coordination among multiple suppliers through system integration. Dispersed deliveries would lead to inconsistent schedules and chaotic processes, resulting in frequent downtime on automakers' assembly lines due to material shortages, posing an extremely difficult challenge to ensuring on-time delivery. Summary of the Invention

Detailed Implementation

[0008] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0009] In the description of this invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0010] like Figures 1-22As shown, this invention discloses an automated warehousing device for rapid turnover of automotive seats, primarily addressing the problem of unpredictable planned volumes for vehicle manufacturers and the inconsistent and chaotic delivery schedules caused by suppliers' fragmented and batch-delivered goods, resulting in frequent downtime and material shortages on vehicle assembly lines. Specifically, it includes an automated warehousing module 25, an empty vehicle conveyor line 40, a high-speed loading line 64, a hoist 31, a stacker 50, a lifting device 67, a vehicle docking line 3, and a lifting and rotating mechanism 53. The automated warehousing module 25 and the hoist 31 are arranged sequentially from left to right along the empty vehicle conveyor line 40. The vehicle docking line 3 is located directly in front of the right end of the automated warehousing module 25 and is used to connect with a docking vehicle 1, which delivers empty vehicles longitudinally. The automated warehousing module 25 can convey the empty vehicles output from the docking vehicle 1 to the hoist 31 to the right. The hoist 31 lifts the empty vehicles and conveys them to the right. At the input end of the conveyor line 40, the empty vehicle conveyor line 40 conveys empty vehicles from left to right in an S-shape. The lifting and rotating mechanism 53 is located at the output end of the empty vehicle conveyor line 40 and is used to rotate the vehicle 13 output from the empty vehicle conveyor line 40 degrees and send it into the loading speed line 64. The loading speed line 64 conveys empty vehicles from right to left. The hanging device 67 is located behind the loading speed line 64 and is used to lift the seat 05 on the finished seat trolley 02 onto the empty vehicle on the loading speed line 64. The stacker 50 is located between the left end of the loading speed line 64 and the automatic storage module 25. The stacker 50 is used to rotate the vehicle with the seat output from the loading speed line 64 by 90 degrees and then convey it forward to the automatic storage module 25. The automatic storage module 25 conveys the vehicle 13 with the seat from left to right in an S-shape to the vehicle connecting line so that the vehicle with the seat can be sent into the connecting vehicle.

[0011] In this embodiment, the automatic storage module 25 has three storage racks, including a feeding storage rack 68, an intermediate storage rack 69, and a connecting storage rack 4 arranged side by side from left to right. The feeding storage rack 68, the intermediate storage rack 69, and the connecting storage rack 4 have the same structure and each has two storage layers, which correspond to the two storage layers inside the body 2 of the connecting vehicle 1. Each storage layer is provided with two storage speed lines 20 distributed to the left and right. The storage speed lines 20 are used to transport the carrier 13 loaded with seats in the front-back direction. Furthermore, in the feeding storage rack 68, each storage speed line 20 is equipped with a first lifting mechanism 24 at its front end, which can lift the vehicle upwards; in the intermediate storage rack 69, each storage speed line 20 is equipped with a second lifting mechanism 28 at both its front and rear ends, which can lift the vehicle upwards; in the connecting storage rack 4, each storage speed line 20 is equipped with a third lifting mechanism 29 at its rear end, which can lift the vehicle upwards, and the storage speed line 20 on the right side is equipped with an empty vehicle lifting mechanism 30 at its front end, which is used to lift and lower the empty vehicle output by the connecting vehicle 1 and convey it to the elevator 31 to the right; the first lifting mechanism 24, the second lifting mechanism 28, the third lifting mechanism 29 and the empty vehicle lifting mechanism 30 have the same structure, and each is equipped with a roller conveyor for conveying the vehicle in the left and right direction at its top.

[0012] When the automated storage module is working, taking the upper storage (i.e., first-level storage 26) as an example (the working process of the lower storage (i.e., second-level storage 27) is the same): the forklift 50 sequentially rotates the carrier 13 loaded with a seat 90 degrees and then conveys it forward to the two storage speed lines 20 of the upper storage 68 of the feeding storage rack. The two storage speed lines 20 of the upper storage 68 of the feeding storage rack convey the carrier 13 loaded with a seat from back to front. The storage speed line 20 on the right side is in front of... The first lifting mechanism 24 at the end lifts the carrier 13 carrying the seat and conveys it to the right to the intermediate storage rack 29 (realizing the transfer between adjacent storage racks). The second lifting mechanism 28 is located at the front end of the storage speed line 20 on the left side. The first lifting mechanism 24 at the front end of the storage speed line 20 on the left side of the feeding storage rack 68 lifts the carrier 13 carrying the seat and conveys it to the right to the storage speed line 20 on the right side, realizing left-right transfer within the same storage rack. The two storage speed lines 20 on the upper storage level of the intermediate storage rack 69 convey the carrier 13 carrying the seat from front to back, and then through the second lifting mechanism 28 at its rear end, convey it to the right to the connecting storage rack 4. The two storage speed lines 20 on the upper storage level of the connecting storage rack 4 convey the carrier carrying the seat from back to front, forming an S-shaped conveyor (e.g., ...). Figure 2As shown in the diagram, the final output is placed into the container 2 of the shuttle vehicle 1. The empty containers output from the rear container of the shuttle vehicle are lifted by a container lifting mechanism and conveyed to the right to the elevator, which then feeds them into the empty container conveyor line. This automated storage module is a fast-in, fast-out series, with a total storage capacity of 24 containers, sufficient for simultaneous shipments from two shuttle vehicles.

[0013] In this embodiment, the empty vehicle conveyor line 40 includes three parallel empty vehicle speed-up lines 41 arranged at equal intervals from left to right. The empty vehicle speed-up lines convey empty vehicles in the front-to-back direction. Each empty vehicle speed-up line 41 has a fourth lifting mechanism 42 at both its front and rear ends. The fourth lifting mechanism is used to lift the empty vehicle upwards. The top of the fourth lifting mechanism 42 is provided with a roller line for conveying the vehicle in the left-to-right direction. A connecting line 43 for conveying the vehicle in the left-to-right direction is provided between each two adjacent empty vehicle speed-up lines 42. That is, the empty vehicle conveyor line has a total of two connecting lines, which are arranged left and right and distributed one in front and one behind. The three speed-up lines increase the volume of returning empty vehicles. Specifically: the connecting line 43 on the left is located between the fourth lifting mechanism 42 at the rear end of two adjacent empty vehicle speed-multiplying lines 41 (the empty vehicle speed-multiplying line on the left and the empty vehicle speed-multiplying line in the middle); the connecting line 43 on the right is located between the fourth lifting mechanism 42 at the front end of two adjacent empty vehicle speed-multiplying lines 41 (the empty vehicle speed-multiplying line in the middle and the empty vehicle speed-multiplying line in the right), so that the entire empty vehicle conveying line forms an S-shaped distribution; the hoist 31 corresponds to the position of the fourth lifting mechanism 42 at the front end of the leftmost empty vehicle speed-multiplying line 41, the hoist lifts the empty vehicle to the same height as the fourth lifting mechanism, and then conveys it to the right onto the fourth lifting mechanism; the lifting and rotating mechanism 53 is located behind the rightmost empty vehicle speed-multiplying line 41, so as to rotate the output empty vehicle 90 degrees (the empty vehicle rotates from a longitudinal state to a lateral state).

[0014] It should be noted that the first, second, third, and fourth lifting mechanisms, as well as the empty vehicle lifting mechanism, have the same structure, including a lifting frame. The roller conveyor is installed on the upper end of the lifting frame, which can be driven up and down by a cylinder vertically set below it to achieve lifting. When the speed line is working normally, the lifting mechanism is in the lower position and does not affect the normal conveying operation of the speed line. When lifting is required, the cylinder drives the lifting frame to move upward, separating the vehicle directly above it from the speed line.

[0015] In this embodiment, the vehicle connection line 3 is used to park the shuttle vehicle 1. The vehicle connection line 3 includes a pad A5, a cylindrical guide rail A6, a cylindrical guide rail B7, a reinforcing block 8, a pad B9, a tire damper 10, a base 21, a guide rail block 22, and a connection guide rail 23. The cylindrical guide rail A6 is located on the side of the pad B9 and is fixed to the ground by the reinforcing block 8. The tire damper 10 and the base 21 are located on the rear side of the pad B9. The guide rail block 22 with a sloping front end and the connection guide rail 23 located between the two guide rail blocks 22 are fixed on both sides of the upper end of the base 21. When shuttle bus 1 returns after unloading the seats (shuttle bus 1 is empty when the seats are unloaded at the vehicle assembly plant), it should stop at the front of vehicle connection line 3. Align the rear cylindrical guide rails A6 and B7 using the rearview mirror (the yellow paint on the guide rails makes them more visible). Use the focused rearview mirror to judge the left and right distance deviations, ensuring that the guide rails are on the same horizontal plane as the connection storage rack (i.e., the seat connection line). The wheels of shuttle bus 1 must drive onto mats A5 and B9. At the end, because the weight difference between the empty and fully loaded vehicle body can cause deviation between the docking line and the docking storage rack, the height needs to be raised when empty. The docking guide rails 23 are guided by cylindrical guide rails A6 and B7 to align the vehicle body guide pillars in the tooling plate with the docking guide rail 23. The docking vehicle continues to back in. Guide wheels are installed on both sides of the lower end of the tooling plate. With the correction of the guide wheel block 22, a final raising is performed. The docking stops when the wheels approach the tire damping 10, and the docking line inside the docking vehicle body 2 aligns with the docking storage rack. It should be noted that the vehicle docking line is the same as the truck docking line in "A Car Seat Circulating Storage Production Line and Its Working Method" disclosed in Chinese Patent Publication No. CN118701562A. Its structure and working principle will not be repeated here.

[0016] In this embodiment, lifting and transmission mechanisms 65 are provided at both ends of the loading speed line 64. The lifting and transmission mechanism 65 located at the right end of the loading speed line 64 corresponds to the lifting and rotating mechanism 53 to receive the empty vehicle after the lifting and rotating mechanism has rotated 90 degrees. The lifting and transmission mechanism 65 located at the left end of the loading speed line 64 is used to forwardly transfer the vehicle 13 of the loaded seat 02 to the forklift 50. It should be noted that the lifting and transmission mechanism is the same as the lifting and transmission mechanism in the "An Automobile Seat Circulating Storage Production Line and Its Working Method" disclosed in Chinese Patent Publication No. CN118701562A, and its structure and working principle will not be described in detail here.

[0017] It should be noted that the aforementioned warehouse speed conveyor, loading speed conveyor, and empty vehicle speed conveyor are all existing products. Speed ​​conveyors, also known as double-speed conveyor lines, are core conveying equipment in the electronics and electrical appliance industry production lines. These self-flowing differential conveyor systems in the electronics and electrical appliance industry employ a chain and roller transmission structure, supporting 2.5x and 3x speed differential modes, with a single-section drive length of 30-40 meters. Their operating accuracy reaches ±0.02mm, achieving a lifting accuracy of 5 microns (0.005mm) through secondary positioning technology, with a failure rate of less than 0.01%. Their specific structure and working principle will not be repeated here.

[0018] In this embodiment, the lifting and rotating mechanism 53 includes a frame 54, a lifting plate 55 lifted by a top cylinder at the lower end of the frame 54, and a guide column assembly 57 around the plate 55 for stable operation. A lower-end barcode reader 59 is used to scan the RFID information of the carrier. A fisheye connector rotates the rotating plate 58 90 degrees via a swing cylinder. Positioning pins 62 and 63 at the upper end of the rotating plate 58 are used to fix the empty carrier. After the empty carrier is precisely repositioned by the rotating plate 58, it is conveyed by the loading speed line 64 and the lifting and transmission mechanism 65. It should be noted that the lifting and rotating mechanism is the same as the lifting and rotating mechanism in the "An Automobile Seat Circulating Storage Production Line and Its Working Method" disclosed in Chinese Patent Publication No. CN118701562A; its structure and working principle will not be described in detail here.

[0019] In this embodiment, as Figure 11-16 As shown, the hanging device 67 is used to assist in transferring seats from the finished seat trolley to the loading speed line. Specifically, it includes a column 01 installed on the front side of the finished seat trolley 02, with the column mounted on the ground. A horizontally positioned rocker arm 03 is rotatably connected to the upper end of the column 01. A wire rope lifting assembly 04 is provided at the end of the rocker arm 03 away from the column. The lifting end of the wire rope lifting assembly 04 is equipped with a clamp 06 for clamping the seat 05. The clamp is connected to the seat on the finished seat trolley, and the clamp and seat are lifted and hoisted (moved up and down) by the wire rope lifting assembly. Finally, the rocker arm rotates (rotates in the horizontal plane) to transfer the seat to the loading speed line. This hanging device facilitates the transfer of seats on the finished seat trolley, improving operational convenience, reducing labor costs, effectively reducing the risk of seats falling during handling, and improving handling efficiency.

[0020] In this hanging device, the clamp 06 includes a vertically arranged clamp bracket 07. The clamp bracket 07 is a rectangular frame with an open front and bottom. The front end of the clamp bracket 07 is provided with a backrest clamping plate 08 and a movable gripping piece 09 distributed vertically. The backrest clamping plate 08 is used to fit against the backrest of the seat 05. The movable gripping piece 09 is used to extend into the gap at the connection of the backrest of the seat 05. The movable gripping piece 09 is driven upward by a clamping drive. In use, the movable gripping piece is inserted into the gap at the connection of the backrest of the seat, and the clamping drive drives the movable gripping piece upward, so that the backrest clamping plate fits against the backrest of the seat, thereby fixing the seat.

[0021] In this hanging device, a horizontally positioned clamp base 010 is fixed to the bottom of the clamp bracket 07. The front end of the clamp base 010 has a pair of left- and right-distributed gripping and fixing plates 011 for inserting into the gap at the backrest connection of the seat 05. A movable gripping plate 09 is positioned between the pair of gripping and fixing plates 011. Normally, the pair of gripping and fixing plates are parallel to the movable gripping plate, and all three are used to insert into the gap at the backrest connection of the seat. During operation, only the movable gripping plate tilts upwards. By setting a pair of gripping and fixing plates, the support effect on the seat during transfer is improved.

[0022] In this hanging device, the rear end of the movable gripper 09 is fixed with a hinge shaft 012, which is rotatably connected to the front end of the clamp base 010 so that the movable gripper 09 and the clamp base 010 form a hinged engagement; the outer surface of the hinge shaft 012 is also fixed with an upward tilting drive plate 013 extending to the rear side and upward, and the clamping drive component is connected to the upward tilting drive plate 013, which drives the movable gripper 09 to tilt upward through the upward tilting drive plate 013. Specifically: the upward-tilting drive plate 013 and the movable gripper 09 are arranged in a V-shape, and the upper end of the upward-tilting drive plate 013 extends into the fixture bracket 07; the clamping drive component includes a clamping drive cylinder 014 vertically installed inside the fixture bracket 07, the upper end of the clamping drive cylinder 014 is hinged to the upper end of the fixture bracket 07, the cylinder rod of the clamping drive cylinder 014 extends downward and its end is hinged to the upward-tilting drive plate 013 through a hinge joint 015. When the cylinder rod of the clamping drive cylinder 014 extends or retracts, it can drive the movable gripper 09 to swing.

[0023] In this hanging device, the chair back clamping plate 08 is inclined with a higher front end and a lower rear end. A pair of connecting rods 016, distributed to the left and right, are fixed to the back of the chair back clamping plate 08. The lower ends of the pair of connecting rods 016 are hinged to the left and right sides of the clamp bracket 07, respectively. Furthermore, the left and right side walls of the clamp bracket 07 are each provided with an arc-shaped groove 017. The lower ends of the pair of connecting rods 016 are each provided with a sliding guide rod 018. The sliding guide rod 018 extends into the corresponding arc-shaped groove 017 and slides within it. It should be noted that the arc length of the arc-shaped groove is relatively short. The sliding guide rod extending into the arc-shaped groove serves two purposes: firstly, it guides the rotation of the connecting rod; secondly, the connecting rod can only rotate within the range of the arc-shaped groove, resulting in a small rotation amplitude.

[0024] In this hanging device, in order to improve the limiting effect, the left and right outer sides of the clamp bracket 07 are respectively fixed with limiting blocks 019. The limiting blocks 019 are located on the rear side of the connecting rod 016 on the same side and are used to limit the backward swing of the connecting rod 016.

[0025] In this hoisting device, both ends of the clamp bracket 07 are fixed with lifting handles 020 for easy gripping, and the lifting handles extend to the rear. By providing two lifting handles on the clamp, it is convenient for the operator to hold, thereby facilitating the movement of the clamp and the seat.

[0026] In this suspension device, the wire rope lifting assembly includes a mounting frame 021, a lifting motor 022, a wire rope 023, and a drum 024. The mounting frame 021 is located at the lower part of the rocker arm 03 away from the column 01. Both the lifting motor 022 and the drum 024 are mounted on the mounting frame 021. The output shaft of the lifting motor 022 is connected to the drum 024 to drive the drum to rotate. One end of the wire rope 023 is wound around the drum 024, and the other end of the wire rope 023 is connected to a lifting ring 025 mounted on a clamp. During operation, the lifting motor drives the drum to rotate, and the drum winds up or unwinds the wire rope. When the wire rope winds up or unwinds, it drives the clamp to move synchronously. When the clamp is connected to the seat, the seat moves up and down synchronously with the clamp. By controlling the forward and reverse rotation of the lifting motor, the switching of wire rope winding or unwinding can be achieved, that is, controlling the up and down movement of the clamp.

[0027] In this hanging device, a rotary motor 026 for driving the rocker arm 03 to rotate around the column 01 is provided on the upper outer surface of the column 01. Specifically, a vertical rotating shaft (not shown in the figure) is provided inside the upper end of the column. The lower end of the vertical rotating shaft is connected to the rotary motor through a pair of gears. The rotary motor drives the vertical rotating shaft to rotate through a pair of gears. The upper end of the vertical rotating shaft extends out of the column and is connected to the rocker arm. When the vertical rotating shaft rotates, it drives the rocker arm to rotate synchronously.

[0028] In this lifting device, the handle 020 is equipped with operating switches 027 for controlling the rotation of the rocker arm 03, the operation of the wire rope lifting assembly, and the operation of the clamping drive component. Specifically, there are multiple operating switches, such as switches for controlling the start / stop and forward / reverse rotation of the rotary motor, switches for controlling the start / stop and forward / reverse rotation of the lifting motor, and switches for controlling the extension or retraction of the clamping drive cylinder. By placing the operating switches above the handle, operation is convenient, enabling rapid single-person operation and handling.

[0029] This lifting device, with its freely rotating and vertically moving clamps, is primarily a tool to assist in the installation and removal of car seats. Its design aims to reduce the force required during operation, improving work efficiency and reducing labor intensity. In use, the fixed and movable clamping plates are inserted into the gap at the seat back connection. When the seat back approaches the seat back clamping plate, the cylinder rod of the clamping drive cylinder extends downwards, driving the movable clamping plate upwards, causing the seat back clamping plate to align with the seat back, thus securing the seat. The wire rope lifting assembly then winds up the wire rope, pulling the clamps and seat upwards to lift the seat. Next, the rocker arm rotates, moving the seat to the loading speed line. The wire rope lifting assembly then releases the wire rope, causing the clamps and seat to descend, aligning the seat legs with the positioning holes on the carrier. Finally, the cylinder rod of the clamping drive cylinder retracts upwards, driving the movable clamping plate downwards to reset, separating the clamps from the seat.

[0030] This lifting device connects to seat clamps, allowing for free rotation and vertical movement. It primarily assists in the installation and removal of car seats, aiming to reduce the force required during operation, thereby improving work efficiency and reducing labor intensity. The device utilizes a rotary motor to power the swing arm, a lifting motor for seat raising and lowering, and clamps for connecting to the seat. Each mechanism is controlled by an operating switch, enabling single-person operation for rapid handling, effectively reducing the risk of seats falling during transport and improving efficiency.

[0031] In this embodiment, as Figure 17-22 As shown, the forklift 50 includes a movable cuboid frame assembly 11. Inside the frame assembly 11, a horizontally oriented lifting platform 12 is installed. The lifting platform supports a carrier 13. A lifting and rotating mechanism 14 is located at the top center of the lifting platform 12, capable of lifting and rotating the carrier 13. Conveyor rollers for conveying the carrier 13 in a forward and backward direction are respectively installed on the left and right sides of the lifting and rotating mechanism 14. By providing a lifting and rotating mechanism on the lifting platform to lift and rotate the carrier, it is easy to reposition the carrier by 90 degrees, making it convenient to use and effectively improving logistics efficiency.

[0032] In this forklift, the liftable and rotating mechanism 14 includes a lifting plate 15 parallel to the center of the lifting platform 12. The lifting plate 15 is driven to move up and down by a top cylinder 16 vertically positioned directly below it, achieving lifting and lowering. A carrier rotating disk 17 is horizontally positioned above the center of the lifting plate 15 for contacting the bottom of the carrier 13. The carrier rotating disk 17 is driven to rotate by a rotating assembly 18. Initially, the carrier rotating disk is positioned below the conveyor roller line, and the bottom of the carrier is in contact with the conveyor roller line. The carrier can be conveyed in the front-to-back direction via the conveyor roller line. When rotation and repositioning are required, the top rod drives the lifting plate and the carrier rotating disk to move upward. The carrier rotating disk contacts the bottom of the seat carrier and lifts the carrier upward, separating the seat carrier from the conveyor roller line. Then, the carrier rotating disk drives the seat carrier to rotate 90 degrees, achieving a 90-degree repositioning. Finally, the carrier rotating disk returns to its original position, allowing the bottom of the seat carrier to re-contact the roller line.

[0033] In this forklift, the rotating assembly 18 includes a gear 19, a rack 110, and a rotary drive cylinder 111. The gear 19 is coaxially fixed to the center of the bottom surface of the carrier rotating disk 17, and the two are connected as a whole. The gear 19 is rotatably mounted at the center of the top surface of the lifting plate 15. The rack 110 is arranged in the front-rear direction and meshes with the gear 19. The bottom of the rack 110 slides with the lifting plate 15 in the front-rear direction. The rotary drive cylinder 111 is arranged parallel to the side of the rack 110. The cylinder rod of the rotary drive cylinder 111 extends forward and is connected to the front end of the rack 110 through a connector 124. When the cylinder rod of the rotary drive cylinder 111 extends or retracts, it drives the rack 110 to move in the front-rear direction. When the rack 110 moves, it drives the gear 19 to rotate. The gear 19 drives the carrier rotating disk 17 to rotate synchronously.

[0034] In this forklift, the lifting and rotating mechanism 14 further includes a fixed plate 112 arranged parallel between the lifting plate 15 and the lifting platform 112. Four vertical guide columns 113 arranged in a matrix are fixedly inserted through the fixed plate 112. The lower ends of the four vertical guide columns 113 are installed on the lifting platform 12, and the upper ends of the four vertical guide columns 113 are slidably engaged with the guide holes on the lifting plate 15 in a vertical direction to guide the up and down movement of the lifting plate. The top cylinder 16 is installed in the middle of the bottom surface of the fixed plate 112. The cylinder rod of the top cylinder passes through the fixed plate upward and is connected to the lifting plate.

[0035] In this forklift, the lifting and rotating mechanism 14 has two conveyor rollers on both the left and right sides, meaning there are four conveyor rollers on the lifting platform 12. The two conveyor rollers located on the same side (both on the left or right) are the inner roller 114 closer to the lifting and rotating mechanism 14 and the outer roller 115 farther away. Specifically, the carrier turntable 117 of the lifting and rotating mechanism has inner rollers 114 on both the left and right sides, and outer rollers 115 are arranged parallel to each inner roller 114. When the carrier 13 is positioned laterally, the inner rollers 114 and outer rollers 115 simultaneously contact the bottom of the carrier 13 and can simultaneously convey the carrier 13 in both forward and backward directions. Figure 21 As shown; when the carrier 13 is rotated 90 degrees by the lifting and rotating mechanism 14 and is arranged longitudinally, only the inner roller conveyor 114 contacts the bottom of the carrier 13, and the carrier is only conveyed by the inner roller conveyor 114 in the front and rear directions, as shown. Figure 22 As shown.

[0036] It should be noted that a roller conveyor (also known as a roller conveyor) is an industrial drive device used to transport items with flat bottoms. It is mainly used in logistics warehousing, manufacturing production lines, and other fields. According to the driving method, it is divided into two categories: powered and unpowered. In this embodiment, a powered type can be used. Since roller conveyors are existing and mature products, their structure and working principle will not be described in detail here.

[0037] In this forklift, a row of guide wheels 116 is provided at both the left and right ends of the top of the lifting platform 12. The row of guide wheels 116 is distributed in the front-to-back direction to facilitate rolling contact with the side of the carrier 13. By setting two rows of guide wheels 113 distributed on the left and right, the forward and backward movement of the carrier is guided, which greatly increases the accuracy of the carrier entering the warehouse and improves logistics efficiency.

[0038] In this forklift, a pair of vertical guide rails 117 are provided at both the left and right ends of the frame assembly 11, and the pair of vertical guide rails 117 are distributed in front and behind; a pair of sliders 118 are provided at both the left and right ends of the lifting platform 12, and the pair of sliders 118 correspond to the positions of the pair of vertical guide rails 117 located on the same side and form a sliding engagement to guide the up and down movement of the lifting platform.

[0039] In this forklift, a pair of lifting chains 119 are provided at both the left and right ends of the frame assembly 11. The pair of lifting chains 119 are distributed front and rear and connected to the lifting platform 12. A sprocket assembly 120 is connected to both the upper and lower ends of the pair of lifting chains 119. The sprocket assembly 120 includes a longitudinally arranged sprocket connecting shaft, with a sprocket installed at each of the front and rear ends of the sprocket connecting shaft. The sprocket assembly 120 at the upper end of the lifting chain 119 on the right end is driven to rotate by a lifting motor 121. The lifting motor can be a servo motor. The lifting motor 121 drives the lifting platform 2 to move vertically up and down through the sprocket assembly and the pair of lifting chains 119.

[0040] In this forklift, a traveling wheel 122 is installed at each of the four top corners of the bottom of the frame assembly 11, and a stepper motor 123 is provided at the lower end of the frame assembly 11 to drive the traveling wheel 122 to rotate along the transverse track.

[0041] The advantages of this stacker are: by adding a lifting and rotating mechanism to the top of the stacker, the carrier can be repositioned by 90 degrees. At the same time, by adding guide wheels, the accuracy of the carrier entering the warehouse is greatly increased, thus improving logistics efficiency.

[0042] In this embodiment, the hoist 31 includes a horizontally arranged lifting arm 35, which is driven to move up and down by a vertically arranged lifting cylinder 36. The lifting arm 35 is equipped with a conveyor roller line 38 for conveying empty vehicles from left to right. The hoist 31 also includes a hoist frame 32, which allows the slider 34 at the upper end of the lifting arm 35 to move freely in a straight line via two side rails 33. The lifting arm 35 is raised and lowered by the lifting cylinder 36 installed at the lower end of the hoist frame 32. The conveyor roller line 38 at the upper end of the lifting arm 35 is used to connect to the vehicle lifting mechanism of the automated storage module. The lifting arm is equipped with a sensor 39 for connecting to the fourth lifting mechanism of the vehicle conveyor line 40. When maintaining a horizontal position, the empty vehicle is sent back into the vehicle conveyor line. The lifting arm 35 descends to the damping 37 and returns to the origin to reset, waiting for the next signal to start operation.

[0043] In this embodiment, the specific workflow is as follows: Based on the characteristics of rapid turnover of car seats, multiple seats are arranged on the back side of the loading speed line 64 through different trolleys 02. The trolleys 02 can be stacked to save space and can be disassembled when needed. After the shuttle vehicle stops at the vehicle shuttle line, the body 225 of the shuttle vehicle 1 is connected to the power supply of the automatic storage module. The vehicle body is transported to the vehicle lifting mechanism at the front end of the automatic storage module. The empty vehicle lifting mechanism 30 lifts the vehicle 13, and the lifting cylinder 36 of the hoist 31 lifts the lifting arm 35 to a certain height, so that the conveyor roller line 38 is level with the empty vehicle lifting mechanism 30. The vehicle 13 is transferred from the roller line on the empty vehicle lifting mechanism 30 to the conveyor roller line 38 on the hoist 31. Then the lifting cylinder 36 returns downward. When the sensor 39 contacts the fourth lifting mechanism at the left front end of the empty vehicle conveyor line 40, the fourth lifting mechanism 42 lifts its roller line to be level with the conveyor roller line 38 of the hoist 31. The vehicle 13 passes through the hoist 31. The conveyor roller 38 conveys the load to the upper end of the fourth lifting mechanism 42 and then lowers back to its original position. The carrier 13 is conveyed in an S-shape to the lifting and rotating mechanism via the empty carrier conveyor 40. The lifting and rotating mechanism 53 rotates the carrier 13 90 degrees. If maintenance is required, the carrier 13 is manually sent out of the line by the fourth lifting mechanism 42 at the rear end through the carrier conveyor. When the reader 59 of the lifting and rotating mechanism 53 contacts the built-in RFID signal of the carrier 13, the top cylinder 56 lifts the lifting plate 55. The positioning pins A62 and B63 at the upper end of the rotating plate 58 fix the built-in hole of the carrier 13. The swing cylinder 60 built into the lifting plate 55 pushes out and rotates the rotating plate 58 90 degrees, sending it into the lifting and transmission mechanism 65. The loading speed line 64 starts and drags the carrier 107 to the left to the designated position for use. Each vehicle model's trolley 02 is positioned behind the loading speed line 64. The seat 05 is grabbed by the hanging device 67, and its legs are aligned with the positioning holes on the carrier 13. A handheld PDA scans the seat's QR code to bind it to the built-in RFID tag on the carrier 13, primarily for recording the type and quantity of the shipped vehicle. The carrier 13 is then conveyed forward to the forklift 50 via the lifting and conveying mechanism 65. The forklift 50 rotates the carrier 90 degrees and then places it into the feeding storage rack 68 of the automated storage module 25. The storage speed line 20 uses an S-shaped loop to transport the carrier 13, loaded with seats, to the vehicle connection line 3, and finally into the container of the connecting vehicle 1 parked on the vehicle connection line 3.

[0044] Each speed-up line is driven by an SEW motor reducer, and the operating speed of the device is adjustable. This is achieved by using a frequency converter. The control system uses a Siemens PLC, which can send the load seat carrier 107 into the designated storage position according to the program settings.

[0045] In this embodiment, due to distance limitations, multiple suppliers typically deliver seat trolleys to a designated delivery point. The delivery point, in addition to its own seats, categorizes the different types of seat trolleys from each supplier. Following a planned sequence, the seats on the trolleys are hoisted onto a carrier on the high-speed conveyor line using a hoisting device. The seats are then linked to the carrier's RFID tag via a PDA scan, and finally, a forklift transports them into the automated storage module. A drag-type high-speed conveyor line is arranged within the storage racks, using chains as the load-bearing and traction conveyor. A roller conveyor chain is employed for high-frequency transport. Lifting mechanisms are used at the ends of the high-speed conveyor line for lateral seat transfer. The storage racks use an S-shaped conveyor system, capable of storing up to 24 sets of complete vehicle seats, sufficient for loading two trucks.

[0046] The advantages of this invention are: (1) The conveying speed is fast and the rate is high, which can ensure accurate synchronous conveying function; (2) It has a large load capacity and can carry materials with large mass, and has a strong conveying capacity; (3) It has a high degree of adaptability to the working environment and can operate normally in various harsh environments. For example, high temperature and dusty environments cannot affect its work progress and have high reliability. (4) By using a single-cycle layout, the investment in shelving is greatly reduced; (5) The vehicle conveyor line adopts an S-shaped conveying method to increase the vehicle storage capacity; empty vehicles are automatically sent into the vehicle conveyor line to reduce manual handling.

[0047] The biggest advantage of this equipment is that it reduces fixed warehousing investment, improves the linkage of delivery systems among various suppliers, achieves seamless connection of unpredictable planned quantities, greatly reduces the downtime of vehicle assembly lines due to material shortages, ensures delivery time, and reduces fixed equipment investment costs.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them; although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of the present invention or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solutions of the present invention, and all such modifications and substitutions should be covered within the scope of the technical solutions claimed in the present invention.
