Description

Technical Field

[0001] This invention relates to the field of storage technology, and in particular to a stacking device for warehousing and logistics. Background Technology

[0002] With the rapid development of the logistics industry, the storage of materials in warehouses has also developed rapidly. Traditional warehouse storage methods involve stacking materials on the factory floor, but due to the limitation on the stacking height, materials are often not stacked too high, thus requiring larger warehouses to store materials. Now, by building shelves in warehouses, the shelves are often several meters to tens of meters high, and each shelf has multiple storage compartments for placing materials.

[0003] In related technologies, a chain roller conveyor is installed between two adjacent shelves, and a sliding movable frame is installed along the movement direction of the chain roller conveyor. The movable frame is equipped with a liftable insert plate, which is used to insert into the pallet below the material. The material is transported to the movable frame by the chain roller conveyor, the insert plate is driven to descend and insert into the pallet, the insert plate is driven to rise and lift the pallet. When it reaches the material placement position, the insert plate is rotated so that it faces the compartment where the material is placed, the insert plate is driven to send the material into the compartment and put it down, and then the insert plate is removed from the pallet and rotated back to its original position.

[0004] When materials need to be removed from a compartment and new materials need to be placed in it, a pallet is required to remove the materials from the compartment and place them on a chain roller conveyor. The chain roller conveyor then transports the materials to the pick-up / drop-off end, where a forklift removes them. Subsequently, the forklift places the new materials on the chain roller conveyor, which then transports them to the moving frame and places them in the compartment. When materials are exchanged, the previous materials need to be unloaded through a platen and a chain roller conveyor, and then the new materials need to be loaded through a chain roller conveyor and a platen. This results in low efficiency in picking up and placing materials, as subsequent unloading and loading operations can only be carried out after the loading and unloading operations are completed.

[0016] In summary, this application includes at least one of the following beneficial technical effects: 1. Material feeding is carried out via an upper-level chain roller conveyor, while material unloading is carried out via a combination of upper-level chain roller conveyors, a lifting chain roller conveyor, and a lower-level chain roller conveyor. This eliminates the need for a single chain roller conveyor for both feeding and unloading, improving material handling efficiency. While the unloading plate picks up the material to be unloaded, the loading plate simultaneously picks up the material to be loaded, further enhancing handling efficiency. To ensure accurate insertion of the unloading plate into the tray's holes, its top surface must be lower than the top surface of the hole. After insertion, the unloading plate is slightly raised to lift the tray. Simultaneously, the loading plate lowers slightly, ensuring its top surface is lower than the top surface of the hole. The unloading plate is then driven... The process involves: retrieving the pallet and driving the rotating frame to rotate 90° while the feeding plate inserts into the hole; lowering the unloading plate and lifting the pallet, enabling bidirectional feeding and unloading; when the unloading plate places the pallet on the top surface of the upper chain roller conveyor, the feeding plate reaches the designated position, drives the rotating frame to rotate 90°, and then drives the feeding plate to send the pallet into the compartment. The feeding plate then lowers slightly to place the pallet and detaches from the pallet, retracts, rotates 90°, and then lowers again. At this time, the unloading plate also rises slightly and continues to rise, achieving position switching between the feeding and unloading plates. The coordinated action of the feeding and unloading plates improves the efficiency of material loading and unloading, and both plates can also be used independently. 2. When the connection between the rotating shaft and the rotating shaft is achieved through the connecting mechanism, the rotation of the two rope reels is synchronized. Therefore, when one rope reel rotates, the rope reel drives the rotating shaft to rotate through the rotating shaft, the rotating shaft drives the sprocket to rotate, the sprocket drives the other sprocket to rotate through the chain, the sprocket drives the rotating shaft to rotate, and the rotating shaft drives the other rope reel to rotate through the rotating shaft. When the loading plate and the unloading plate simultaneously insert and pick up the pallet, the gravitational potential energy generated by the material falling on the unloading plate can be used to drive the material on the loading plate to rise. The additional kinetic energy is generated by the lifting motor used to lift the loading plate. 3. When the two rope reels need to be linked, the electric push rod drives the connecting plate to move. The connecting plate drives the sliding tube to move towards the sprocket, so that the first spline shaft located in the annular groove enters the first spline groove, realizing the connection between the rotating tube and the rotating shaft. The sliding block slides in the sliding groove, maintaining the connection between the rotating tube and the sliding tube. At this time, the connection between the rotating shaft and the rotating shaft is realized, and the linkage of the two rope reels can be realized. When the linkage of the two rope reels is not needed, the electric push rod drives the connecting plate to move back. The connecting plate drives the sliding tube to move back, so that the first spline shaft enters the annular groove. At this time, the first spline shaft is not connected to the rotating tube, and the first spline shaft rotates freely in the annular groove. Attached Figure Description

[0019] The following is in conjunction with the appendix Figures 1 to 11 This application will be described in further detail.

[0020] This application discloses a stacking device for warehousing and logistics. (Refer to...) Figure 1 Material 01 is placed on the top surface of tray 02. The size of tray 02 is larger than that of material 01. Through holes 021 are provided on the perimeter of tray 02.

[0021] Reference Figures 2-11The stacking device includes an upper chain roller conveyor 11, a lower chain roller conveyor 12, a lifting chain roller conveyor 13, a movable frame 2, a loading plate 3, and a unloading plate 4. The lower chain roller conveyor 12 is installed on the ground 10, and the support legs of the upper chain roller conveyor 11 are installed on the top surface of the frame of the lower chain roller conveyor 12. The lifting chain roller conveyor 13 is located at the same end of the upper chain roller conveyor 11 and the lower chain roller conveyor 12. A lifting mechanism 5 for driving the lifting chain roller conveyor 13 to rise and fall is provided below the lifting chain roller conveyor 13. 11 and the lower chain roller conveyor 12 have opposite conveying directions; the movable frame 2 spans across both sides of the lower chain roller conveyor 12 and slides along the conveying direction of the chain roller conveyor. Sliding frames 25 are installed on both sides of the movable frame 2 symmetrically. Two lifting mechanisms 6 are installed on the top of the movable frame 2 to drive the two sliding frames 25 to rise and fall respectively. A rotating frame 26 is rotatably connected to the bottom surface of the sliding frame 25. A sliding plate 27 is slidably connected to the bottom surface of the rotating frame 26. The unloading plate 4 is installed at the bottom of the sliding plate 27 near the lifting chain roller conveyor 13, and the loading plate 3 is installed at the bottom of the sliding plate 27 away from the lifting chain roller conveyor 13.

[0022] When material 01 needs to be unloaded, the lifting mechanism 6 drives the sliding frame 25 with the unloading plate 4 to rise, so that the unloading plate 4 reaches the designated height. The rotating frame 26 is then driven to rotate 90°, aligning the unloading plate 4 with the hole 021 of the pallet 02 below the material 01. The unloading plate 4 is then driven to slide along the rotating frame 26, inserting itself into the hole 021 of the pallet 02. The unloading plate 4 is then driven to rise, lifting the pallet 02. The sliding frame 25 is then driven to descend, lowering the unloading plate 4 until the pallet 02 is placed on the rollers of the upper chain roller conveyor 11. After detaching from pallet 02, the drive plate 4 is pulled out from the hole 021 of pallet 02. The upper chain roller conveyor 11 drives pallet 02 to slide towards the lifting chain roller conveyor 13. Pallet 02 slides to above the rollers of the lifting chain roller conveyor 13. The lifting mechanism 5 drives the lifting chain roller conveyor 13 to descend, aligning it with the lower chain roller conveyor 12. The lifting chain roller conveyor 13 drives pallet 02 to slide towards the lower chain roller conveyor 12. The lower chain roller conveyor 12 drives pallet 02 to the end away from the lifting chain roller conveyor 13 for unloading.

[0023] Simultaneously with the above-mentioned unloading process, the feeding plate 3 moves to the top surface of the upper chain roller conveyor 11. The upper chain roller conveyor 11 conveys the new material 01 from the end away from the lifting chain roller conveyor 13 to the feeding plate 3, driving the feeding plate 3 to insert into the hole 021 of the tray 02. The lifting mechanism 6 drives the sliding frame 25 to rise, and the sliding frame 25 drives the feeding plate 3 to rise. The feeding plate 3 lifts the tray 02 and raises it to the designated position. The rotating frame 26 is driven to rotate 90° so that the feeding plate 3 faces the material 01 placement position. The feeding plate 3 is driven to push forward and send the tray 02 into the compartment. The tray 02 is lowered so that the feeding plate 3 is detached from the tray 02 and pulled out of the tray 02.

[0024] For the above process, the material is fed through the upper chain roller conveyor 11, and the material is unloaded through a combination of the upper chain roller conveyor 11, the lifting chain roller conveyor 13, and the lower chain roller conveyor 12. This eliminates the need for a single chain roller conveyor to transport the material 01, thus separating the feeding and unloading processes and improving the material 01 conveying efficiency. While the unloading plate 4 is picking up the material 01 to be unloaded, the feeding plate 3 is simultaneously picking up the material to be fed. 01. Separate loading and unloading operations help improve material handling efficiency; to ensure the unloading plate 4 can accurately insert into the hole 021 of the tray 02, the top surface of the unloading plate 4 needs to be lower than the top surface of the hole 021. After the unloading plate 4 is inserted into the hole 021, lift the unloading plate 4 slightly so that it supports the tray 02. While lifting the unloading plate 4 slightly, the loading plate 3 lowers slightly so that the top surface of the loading plate 3 is lower than the top surface of the hole 021; drive The unloading plate 4 retracts, removing the pallet 02, and drives the rotating frame 26 to rotate 90°. Simultaneously, the loading plate 3 inserts into the hole 021. The unloading plate 4 descends, and the loading plate 3 lifts the pallet 02, achieving bidirectional loading and unloading operations. When the unloading plate 4 places the pallet 02 on the top surface of the upper chain roller conveyor 11, the loading plate 3 reaches the designated position, drives the rotating frame 26 to rotate 90°, and then drives the loading plate 3 to send the pallet 02 into the partition. In between, the loading plate 3 is driven to descend slightly to place the tray 02 and detach the loading plate 3 from the tray 02. The loading plate 3 is then retracted and rotated 90° before descending again. At this time, the unloading plate 4 also rises slightly and continues to rise, thus realizing the position swapping of the loading plate 3 and the unloading plate 4. The synergistic effect of the loading plate 3 and the unloading plate 4 can improve the efficiency of loading and unloading the material 01. The loading plate 3 and the unloading plate 4 can also be used independently.

[0025] The lifting mechanism 5 includes a support base 51, a support frame 52, a support plate 53, a first lead screw 54, a first pulley assembly 55, and a first motor 56. The support base 51 is located at the end of the lower chain roller conveyor 12. The support frame 52 is installed on the top surface of the support base 51. The bottom end of the first lead screw 54 passes through the bottom surface of the support base 51 and is rotatably connected inside the support base 51. The top end of the first lead screw 54 is rotatably connected to the top of the support frame 52. The support plate 53 is installed on the end face of the lifting chain roller conveyor 13 away from the upper chain roller conveyor 11. The first lead screw 54 passes through the support plate 53 and is threaded. Guide plates 57 are connected to both sides of 13. A first guide rod 58 slides inside the guide plate 57. The bottom end of the first guide rod 58 is connected to the support base 51, and the top end of the first guide rod 58 is connected to the top of the support frame 52. A first motor 56 is installed on the top surface of the support base 51. The output shaft of the first motor 56 passes through the bottom surface of the support base 51. A first pulley assembly 55 is installed on the output shaft of the first motor 56 and the bottom end of the first lead screw 54. The two synchronous pulleys of the first pulley assembly 55 are coaxially connected to the output shaft of the first motor 56 and the bottom end of the first lead screw 54, respectively. The synchronous belt of the first pulley assembly 55 is wound around the two synchronous pulleys.

[0026] When it is necessary to drive the lifting chain roller conveyor 13 to rise or fall, the first motor 56 drives the synchronous pulley and synchronous belt in the first pulley assembly 55, and drives the first lead screw 54 to rotate through the synchronous pulley and synchronous belt. The first lead screw 54 drives the pallet 53 to rise or fall, and the pallet 53 drives the lifting chain roller conveyor 13 to rise or fall. The lifting chain roller conveyor 13 slides on the first guide rod 58 through the guide plate 57.

[0027] The lower chain roller conveyor 12 is equipped with rails 7 on both sides, and the rails 7 are installed on the ground 10. The bottom of both sides of the movable frame 2 slides on the two rails 7. The two rails 7 are equipped with racks 71 on their opposite sides. The bottom of both sides of the movable frame 2 is equipped with drive motors 72. The output shaft of the drive motor 72 is coaxially connected to a gear 73, and the gear 73 meshes with the rack 71.

[0028] When the moving frame 2 needs to be driven to move along the conveying direction of the chain roller conveyor, the drive motor 72 drives the gear 73 to rotate. Since the gear 73 meshes with the fixed rack 71, the rack 71 reacts to the gear 73, causing the gear 73 to roll on the rack 71. The gear 73 drives the drive motor 72 to move along the length of the rack 71. The motor drives the moving frame 2 to slide, and the moving frame 2 can then drive the loading plate 3 and the unloading plate 4 to move to different positions.

[0029] The movable frame 2 includes uprights 21, a top plate 22, slides 23, and mounting beams 24. Four slides 23 are provided, with two slides 23 mounted on one track 7 and the other two slides 23 mounted on another track 7. Two rows of rollers 231 are rotatably connected inside each slide 23; one row of rollers 231 rolls on the top surface of the track 7, and the other row of rollers 231 rolls on the side of the track 7 near the other track 7. Four uprights 21 are provided, each connected to the top surface of one of the four slides 23, and the top plate 22 is mounted on the top of each of the four uprights 21. Two mounting beams 24 are provided, with one mounting beam 24 mounted on the top surface of two slides 23 on the same side, and the other mounting beam 24 mounted on the top surface of two slides 23 on the other side. Two drive motors 72 are respectively mounted on the two mounting beams 24.

[0030] When the drive frame 2 moves, the drive motor 72 drives the mounting beam 24 to move, the mounting beam 24 drives the slide 23 to move, the slide 23 slides on the track 7 through two rows of rollers 231, and the slide 23 drives the upright 21 and the top plate 22 to move.

[0031] The sliding frame 25 includes a crossbeam 251, a movable plate 252, and a lifting frame 253. Two lifting frames 253 are provided, each mounted on a separate upright 21. Slide rails 211 are connected to the outer sides of the upright 21, and these slide rails 211 are arc-shaped protrusions. Two rollers 2531 with perpendicular axes are rotatably connected to the bottom and top of the lifting frame 253. The rollers 2531 have inwardly recessed circumferences. The two rollers 2531 at the top are respectively attached to the surfaces of the two slide rails 211, and the two rollers 2531 at the bottom are respectively attached to the surfaces of the two slide rails 211. The two ends of the crossbeam 251 are mounted on the adjacent sides of the lifting frame 253, and the movable plate 252 is mounted on the side of the crossbeam 251 closest to the other sliding frame 25. A rotating frame 26 rotates on the bottom surface of the movable plate 252, and a lifting mechanism 6 is used to lift the crossbeam 251.

[0032] In order to ensure the stability of the sliding frame 25 when it is driven to rise and fall, a slide rail 211 is set on the upright 21 and a roller 2531 is set inside the lifting frame 253. The roller 2531 and the slide rail 211 work together to restrict the horizontal movement of the sliding frame 25, so that the sliding frame 25 can only rise and fall along the slide rail 211. Since the slide rail 211 and the roller 2531 are in close contact, the lifting frame 253 runs more smoothly.

[0033] Two second guide rods 261 are installed inside the rotating frame 26 along the material 01 conveying direction, and the sliding plate 27 slides on the second guide rods 261; a second lead screw 262 is rotatably connected between the two ends of the rotating frame 26, and the second lead screw 262 passes through the sliding plate 27 and is threaded; a second motor 263 is installed on one side of the rotating frame 26, and the output shaft of the second motor 263 faces away from the other rotating frame 26; a second pulley assembly 264 is installed between the output shaft of the second motor 263 and the end of the second lead screw 262; the feeding plate 3 and the discharging plate 4 have the same structure, the top of the feeding plate 3 and the discharging plate 4 are connected to the side of the sliding plate 27, and the bottom of the feeding plate 3 and the discharging plate 4 are bent outward at 90° to be inserted into the hole 021 of the tray 02.

[0034] When pallet 02 needs to be lifted, the second motor 263 drives the synchronous pulley and synchronous belt in the second pulley assembly 264 to drive the second lead screw 262 to rotate. The second lead screw 262 drives the sliding plate 27 to slide on the second guide rod 261. The sliding plate 27 moves towards pallet 02, so that the loading plate 3 and unloading plate 4 are inserted into the hole 021 of pallet 02. The loading plate 3 and unloading plate 4 are lifted to raise pallet 02. Then the second motor 263 drives the second lead screw 262 to rotate again through the second pulley assembly 264. The second lead screw 262 drives the sliding plate 27 to move back. The sliding plate 27 drives the loading plate 3 and unloading plate 4 to move back. The loading plate 3 and unloading plate 4 bring pallet 02 back to below the rotating frame 26.

[0035] Two third guide rods 2511 are inserted inside the crossbeam 251, and one end of each third guide rod 2511 is connected to the side of the movable plate 252 near the crossbeam 251. A third lead screw 2512 is inserted inside the crossbeam 251, and one end of the third lead screw 2512 is rotatably connected to the side of the movable plate 252 near the crossbeam 251. A transmission sleeve 2513 is externally threaded to the third lead screw 2512, and the transmission sleeve 2513 and the third lead screw 2512 are threadedly driven.

An opening is provided on the mounting shell 2515 for the third pulley assembly 2517 to extend into.

[0036] To facilitate the rotation of the loading plate 3 and the unloading plate 4 and reduce the obstruction of the uprights 21 to the loading plate 3 and the unloading plate 4, the third motor 2516 drives the transmission sleeve 2513 to rotate through the third pulley assembly 2517. The transmission sleeve 2513 drives the third lead screw 2512 to move along the axis of the transmission sleeve 2513. The third lead screw 2512 drives the movable plate 252 to move towards the middle position of the moving frame 2, so that the rotating frame 26 is in the middle position of the moving frame 2. At this time, the rotating frame 26 is driven to rotate, and the obstruction of the uprights 21 to the loading plate 3 and the unloading plate 4 is reduced, making it easier for the loading plate 3 and the unloading plate 4 to rotate. After rotation, the loading plate 3 and the unloading plate 4 are in the middle position of the two uprights 21, so the tray 02 and the material 01 are also in the middle position, making it easy to pick up and put down the material 01.

[0037] A rotating shaft 2521 is rotatably connected inside the movable plate 252. The bottom end of the rotating shaft 2521 is connected to the middle position of the rotating frame 26, and the top end of the rotating shaft 2521 passes through the top surface of the movable plate 252. A fourth motor 2522 is installed on the top surface of the movable plate 252, and a fourth pulley assembly 2523 is installed between the output shaft of the fourth motor 2522 and the top end of the rotating shaft 2521.

[0038] When it is necessary to drive the rotating frame 26 to rotate, the fourth motor 2522 drives the rotating shaft 2521 to rotate through the fourth pulley assembly 2523. The rotating shaft 2521 can then drive the rotating frame 26 to rotate, thereby enabling the rotation of the loading plate 3 and the unloading plate 4.

[0039] The lifting mechanism 6 includes a lifting motor 61, a rotating shaft 62, a rope reel 63, a traction rope 64, and a guide assembly 65.

The rope reel 63 is coaxially connected to the rotating shaft 62. One end of the traction rope 64 is wound around the circumference of the rope reel 63, and the other end of the traction rope 64 is connected to the top surface of the crossbeam 251. The lifting motor 61 is mounted on the top surface of the top plate 22, and the output shaft of the lifting motor 61 is connected to the end of the rotating shaft 62. The guide assembly 65 is mounted on the top surface of the top plate 22 and is used to guide the traction rope 64 to be evenly wound around the circumference of the rope reel 63.

[0040] The guiding assembly 65 includes a linear guide rail 651, a movable plate 652, a bidirectional lead screw 653, a guiding motor 654, and a guiding wheel 655. The linear guide rail 651 is mounted on the top surface of the top plate 22 and is arranged along the axis of the rope reel 63. The bottom end of the movable plate 652 is slidably connected to the linear guide rail 651. The guiding motor 654 is mounted on the top surface of the top plate 22. One end of the bidirectional lead screw 653 is connected to the output shaft of the guiding motor 654.

The bidirectional lead screw 653 and the movable plate 652 are threadedly driven. The guiding wheel 655 is rotatably connected to the top of the movable plate 652. The circumferential surface of the guiding wheel 655 is recessed to form a groove for limiting the traction rope 64. The traction rope 64 is wound around the circumferential surface of the guiding wheel 655.

[0041] When the crossbeam 251 needs to be lifted, the lifting motor 61 drives the rotating shaft 62 to rotate, and the rotating shaft 62 drives the rope reel 63 to rotate. The rope reel 63 winds the traction rope 64. In order to make the traction rope 64 wind more evenly on the rope reel 63, the guide motor 654 drives the double-acting screw 653 to rotate. The double-acting screw 653 drives the moving plate 652 to reciprocate along the linear guide rail 651. The moving plate 652 drives the guide wheel 655 to reciprocate. The guide wheel 655 guides the traction rope 64 to be evenly wound on the rope reel 63. When releasing the traction rope 64, it is also released through the guide wheel 655.

[0042] The top surface of the top plate 22 is connected to two support plates 8, which are located at one end of the rotating shaft 62 respectively. The support plates 8 are rotatably connected to the rotating shafts 81, and the two rotating shafts 81 are collinear with the axes of the two rotating shafts 62. The rotating shaft 62 used for pulling the loading plate 3 is connected to the rotating shaft 81, and a connecting mechanism 9 is provided between the rotating shaft 62 used for pulling the unloading plate 4 and the rotating shaft 81. Both rotating shafts 81 are coaxially connected to sprockets 82, and chains 83 are wound around the two sprockets 82.

[0043] When the connection between the rotating shaft 81 and the rotating shaft 62 is achieved through the connecting mechanism 9, the rotation of the two rope reels 63 is synchronized. Therefore, when one of the rope reels 63 rotates, the rope reel 63 drives the rotating shaft 81 to rotate through the rotating shaft 62. The rotating shaft 81 drives the sprocket 82 to rotate. The sprocket 82 drives the other sprocket 82 to rotate through the chain 83. The sprocket 82 drives the rotating shaft 81 to rotate. The rotating shaft 81 drives the other rope reel 63 to rotate through the rotating shaft 62. When the loading plate 3 and the unloading plate 4 simultaneously insert the tray 02, the material 01 on the loading plate 3 can be lifted by the gravitational potential energy generated by the descent of the material 01 on the unloading plate 4. The additional kinetic energy is generated by the lifting motor 61 used to lift the loading plate 3.

[0044] The connecting mechanism 9 includes a rotating tube 91, a sliding tube 92, a connecting plate 93, and an electric push rod 94; three equal-length first spline shafts 811 are provided on the rotating shaft 81 near the feeding plate 4; the sliding tube 92 is sleeved on the rotating shaft 81, and the inner wall of the sliding tube 92 is provided with three first spline grooves 921 that cooperate with the three first spline shafts 811; an annular groove 922 is provided between two adjacent first spline grooves 921, which surrounds the inner wall of the sliding tube 92 and is used for the first spline shafts 811 to enter; the connecting plate One end of the sliding tube 93 is rotatably connected to the end of the sliding tube 92 near the sprocket 82. The electric push rod 94 is installed on the top surface of the top plate 22. One end of the piston rod of the electric push rod 94 is connected to the bottom of the connecting plate 93. One end of the rotating tube 91 is connected to the end of the rotating shaft 62 near the rotating shaft 81. The rotating tube 91 is sleeved on the outer circumferential surface of the sliding tube 92. Multiple sliding blocks 923 arranged along the axis are connected to the outer circumferential surface of the end of the sliding tube 92 near the rotating tube 91. The inner wall of the rotating tube 91 is provided with a sliding groove 911 that cooperates with the sliding block 923.

[0045] When the two rope reels 63 need to be linked, the electric push rod 94 drives the connecting plate 93 to move. The connecting plate 93 drives the sliding tube 92 to move towards the sprocket 82, so that the first spline shaft 811 located in the annular groove 922 enters the first spline groove 921, realizing the connection between the rotating tube 91 and the rotating shaft 81. The sliding block 923 slides in the sliding groove 911 to maintain the connection between the rotating tube 91 and the sliding tube 92. At this time, the connection between the rotating shaft 62 and the rotating shaft 81 is realized, and the linkage of the two rope reels 63 can be realized. When the linkage of the two rope reels 63 is not needed, the electric push rod 94 drives the connecting plate 93 to move back. The connecting plate 93 drives the sliding tube 92 to move back, so that the first spline shaft 811 enters the annular groove 922. At this time, the first spline shaft 811 is not connected to the rotating tube 91, and the first spline shaft 811 rotates freely in the annular groove 922.

[0046] The end of the rotating shaft 62 is connected to the second spline shaft 621, and the end of the lifting motor 61 is connected to the third spline shaft 611. The circumferential surface of the second spline shaft 621 is slidably connected to the moving tube 622. The inner wall of the moving tube 622 is provided with a second spline groove 6221 that cooperates with the second spline shaft 621 and the third spline shaft 611. The outer circumferential surface of the moving tube 622 is rotatably connected to the push-pull plate 623. The bottom end of the push-pull plate 623 is bent 90° toward another lifting mechanism 6. One end of the connecting rod 624 is connected to the side of the bottom end of the push-pull plate 623. The other end of the connecting rod 624 is bent 90° and connected to the side of the connecting plate 93. A sliding plate 625 is passed through the bottom end of the push-pull plate 623. The two ends of the sliding plate 625 are bent downward and connected to the top surface of the top plate 22.

[0047] When the rotating shaft 81 and the sliding tube 92 are connected, the connecting plate 93 drives the connecting rod 624 to move towards the sprocket 82. The connecting rod 624 drives the push-pull plate 623 to move. The push-pull plate 623 slides on the sliding plate 625. The push-pull plate 623 drives the moving tube 622 to move, causing the third spline shaft 611 in the moving tube 622 to disengage from the moving tube 622, thus releasing the connection between the output shaft of the lifting motor 61 and the rotating shaft 62. The linkage between the two winding discs is no longer constrained by the lifting motor 61.

[0048] The upper chain roller conveyor 11, the lower chain roller conveyor 12, and the lifting chain roller conveyor 13 are installed in the trough 101 set on the ground 10, with the upper chain roller conveyor 11 slightly higher than the surface of the ground 10. By setting the upper chain roller conveyor 11, the lower chain roller conveyor 12, and the lifting chain roller conveyor 13 underground, the space occupied by the chain roller conveyor on the ground 10 can be saved.

[0049] The implementation principle of a stacking device for warehousing and logistics in this application embodiment is as follows: Material loading is conveyed via an upper chain roller conveyor 11, and material unloading is conveyed via a combination of the upper chain roller conveyor 11, a lifting chain roller conveyor 13, and a lower chain roller conveyor 12. This eliminates the need for a single chain roller conveyor to transport the material 01, as loading and unloading are separated, improving the material 01 conveying efficiency. When the unloading plate 4 inserts the material 01 to be unloaded, the loading plate 3... Simultaneously, the material 01 to be loaded is inserted and picked up, with loading and unloading operations performed separately, which helps improve material handling efficiency. To ensure the unloading plate 4 can accurately insert into the hole 021 of the tray 02, the top surface of the unloading plate 4 needs to be lower than the top surface of the hole 021. After the unloading plate 4 is inserted into the hole 021, it is raised slightly to lift the tray 02. While raising the unloading plate 4 slightly, the loading plate 3 is lowered slightly so that its top surface is lower than the hole. The top surface of 021; drive the unloading plate 4 to retract, remove the pallet 02, and drive the rotating frame 26 to rotate 90°, while the loading plate 3 inserts into the hole 021; the unloading plate 4 descends, and the loading plate 3 lifts the pallet 02, realizing bidirectional loading and unloading operation; when the unloading plate 4 places the pallet 02 on the top surface of the upper chain roller conveyor 11, the loading plate 3 reaches the designated position, drives the rotating frame 26 to rotate 90°, and then drives the loading plate 3 to lift the pallet 02. 2. The material is fed into the compartment, and the feeding plate 3 is driven to descend slightly to place the tray 02 and detach the feeding plate 3 from the tray 02. The feeding plate 3 is then retracted and rotated 90° before descending. At this time, the unloading plate 4 also rises slightly and continues to rise, thus realizing the position swapping of the feeding plate 3 and the unloading plate 4. The synergistic effect of the feeding plate 3 and the unloading plate 4 can improve the efficiency of loading and unloading the material 01. The feeding plate 3 and the unloading plate 4 can also be used independently.

[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
