Description

Technical Field

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

[0002] Warehousing and logistics systems are comprehensive operational systems that integrate cargo storage, sorting, handling, distribution, and information management. They aim to achieve efficient cargo flow and precise control. Stacking equipment, as a key piece of equipment in this system, is a core tool for dealing with automated warehousing scenarios. Through automated or semi-automated mechanical structures, it enables precise storage and retrieval of goods between high-rise shelves. It not only breaks through the limitations of traditional warehousing's planar space, increasing storage capacity several times over, but also replaces manual labor in high-risk, high-intensity tasks such as heavy object handling and high-altitude operations, significantly reducing labor costs and operational errors. Furthermore, when linked with a warehouse management system (WMS), it can achieve 24-hour continuous operation, greatly improving inbound and outbound efficiency and logistics response speed. It is an indispensable infrastructure for the transformation of modern warehousing towards intelligence and intensification.

[0003] A warehousing and logistics stacking device as described in CN202420064327.4 includes a pallet. Two forklift slots are provided at one end of the pallet. Extension seats are symmetrically arranged on both sides of the pallet. A support cylinder is provided at the top of each extension seat. A movable cavity is formed inside the support cylinder, extending through the top of the support cylinder. A movable rod is slidably connected inside the movable cavity, with one end extending above the support cylinder. A first fixing hole is provided on one side of the support cylinder, communicating with the movable cavity. A first fixing bolt is threaded into the first fixing hole, with the threaded end of the first fixing bolt abutting against the movable rod. The purpose of this device is to solve the technical problem of goods on top easily falling due to shaking, causing inconvenience during transportation.

[0004] However, when stacking goods that are high in height or heavy in weight, the overall stability and load-bearing capacity of the equipment will face severe challenges. This challenge is particularly prominent when the center of gravity of the goods shifts or the ground is uneven. It is very likely to cause safety accidents such as equipment imbalance and tipping, which in turn can damage the goods, personnel and the surrounding environment. Summary of the Invention

[0006] To achieve the above objectives, the present invention provides a stacking device for a warehousing and logistics system, comprising a stacking mechanism, a support platform, and a fixed frame. The stacking mechanism includes two stacking forks, a movable seat, and two stacking screws. The movable seat has stacking threaded grooves and stacking positioning grooves at both ends.

Multiple casters are disposed below the fixed frame. The forks are fixedly mounted on the movable seat, which is slidably mounted in the U-shaped groove. Two stacking positioning rods pass through the movable seat. Each stacking fork abuts against the corresponding lifting roller and is located on the upper end face of the bearing platform. Two stacking screws are rotatably mounted in the U-shaped groove via bearings. The two stacking screws are also threaded into the corresponding stacking thread grooves. The two stacking screws are connected by two stacking synchronous pulleys and a stacking synchronous belt. One of the stacking synchronous pulleys is driven by a stacking motor. The bearing platform is located between the two lifting mechanisms and is slidably mounted in the fixed frame.

[0007] The lifting mechanism includes a fixed plate, two chains, and two rotating shafts. Each rotating shaft is equipped with two sprockets. The fixed plate is bolted to the outside of the bearing platform. The fixed plate is also bolted to the two chains. The two chains are respectively engaged with the two sprockets between the two rotating shafts. The two rotating shafts are rotatably mounted on the outside of the fixed frame through bearings, and one of the rotating shafts is driven by a power assembly.

[0008] The lifting mechanism further includes a lifting positioning sleeve and a lifting positioning rod. The lifting positioning sleeve is fixedly mounted on the fixed plate and slidably mounted on the lifting positioning rod. The lifting positioning rod is mounted on the outside of the fixed frame via two U-shaped seats, and the rotating shaft is located inside the U-shaped seats.

[0009] The power assembly includes a drive gear, a driven gear, a power shaft, and a power box. The drive gear is rotatably mounted in the power box via a power motor. The driven gear is mounted on the power shaft, which is rotatably mounted in the power box. The drive gear meshes with the driven gear. One of the rotating shafts is connected to the power shaft via two power synchronous pulleys and a power synchronous belt. The power box is mounted on the fixed frame.

[0010] The number of external teeth of the driving gear is less than the number of external teeth of the driven gear, and the driving gear is located to the side and below the driven gear.

[0011] The fixed frame has maintenance threaded grooves at each of its four bottom corners, and maintenance support screws are threaded into the maintenance threaded grooves. A rotating disk is provided above the maintenance support screws, and a support foot is provided below the maintenance support screws. The fixed frame also has auxiliary handles at each of its four bottom corners for rotating the maintenance support screws.

[0012] The present invention also provides a stacking method for a warehousing and logistics system, applied to the stacking equipment for the warehousing and logistics system described above, comprising the following steps: S1: Move the stacking equipment to the location of the goods to be stacked by flexibly moving the casters under the fixed frame; S2: Based on the power motor driving the drive gear to rotate, which in turn drives the driven gear and the power shaft to rotate, the power synchronous pulley and the power synchronous belt drive the rotating shaft to rotate, and the sprocket on the rotating shaft drives the chain to move, which drives the fixed plate and the carrying platform to rise and fall, adjusting the carrying platform to a suitable height to receive goods; S3: Based on the stacking motor driving the stacking synchronous wheel and stacking synchronous belt, the two stacking screws are driven to rotate synchronously. The moving seat slides along the U-shaped groove under the drive of the stacking screws, and the two stacking forks move with the moving seat and insert into the bottom of the goods pallet. S4: Then, based on the chain drive, the carrying platform is raised and the stacking forks lift the cargo pallet. Then, the two stacking screws are controlled to control the stacking forks to move the cargo pallet onto the carrying platform. Finally, the cargo is moved to the designated position through the stacking handle and casters. The cargo is stacked according to the above operation. S5: After completing this stacking operation, the platform is lowered to its initial position based on the starting power component, ready for the next stacking operation.

[0013] This invention discloses a stacking device and method for a warehousing and logistics system. The fixed frame provides the basic support framework for the entire device. The carrying platform slides within the fixed frame via a lifting mechanism to adjust the height of the goods. The U-shaped groove, stacking positioning rod, and C-shaped fence on the carrying platform provide positioning and protection for the goods, preventing them from slipping due to a shift in the center of gravity during stacking. In the stacking mechanism, two stacking forks are fixed to a movable seat, which slides within the U-shaped groove. Two stacking screws are connected via a stacking synchronous wheel and a stacking synchronous belt, and driven by a stacking motor to achieve stable movement of the stacking forks, thus smoothly stacking the goods. In the lifting mechanism, the fixed plate, chain, rotating shaft, and power component cooperate to provide stable power for the lifting of the carrying platform. Simultaneously, the lifting positioning sleeve and lifting positioning rod further ensure the stability of the lifting process, preventing the device from becoming unbalanced or tipping over due to heavy goods or a shift in the center of gravity, thus ensuring the safety of goods, personnel, and the surrounding environment.

Detailed Implementation

[0028] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0029] Please see Figures 1-11This invention provides a stacking device for a warehousing and logistics system, comprising a stacking mechanism, a support platform 1, and a fixed frame 2. The stacking mechanism includes two stacking forks 3, a movable seat 4, and two stacking screws 5. The movable seat 4 has stacking threaded grooves 6 and stacking positioning grooves 7 at both ends. The support platform 1 has a U-shaped groove 8, within which two stacking positioning rods 9 are arranged. Multiple lifting rollers 10 are arranged at both openings of the U-shaped groove 8. A C-shaped guardrail 11 is arranged on the outer side of the support platform 1. Two lifting mechanisms are arranged on the outer side of the fixed frame 2. Two push handles 12 are arranged on the fixed frame 2. Multiple casters 13 are arranged below the fixed frame 2. The two stacking forks 3 are respectively... The system is fixedly mounted on the movable seat 4, which is slidably mounted in the U-shaped groove 8. Two stacking positioning rods 9 pass through the movable seat 4. Each stacking fork 3 abuts against the corresponding lifting roller 10 and is located on the upper end face of the bearing platform 1. Two stacking screws 5 are rotatably mounted in the U-shaped groove 8 via bearings. The two stacking screws 5 are also threaded into the corresponding stacking thread groove 6. The two stacking screws 5 are connected by two stacking synchronous pulleys 14 and a stacking synchronous belt 15. One of the stacking synchronous pulleys 14 is driven by a stacking motor 16. The bearing platform 1 is located between the two lifting mechanisms and is slidably mounted in the fixed frame 2.

[0030] In this embodiment, the stacking mechanism, the supporting platform 1, and the fixed frame 2 work together to achieve the stacking operation of goods. The threaded engagement between the stacking screw 5 and the stacking threaded groove 6, as well as the connection between the stacking synchronous wheel 14 and the stacking synchronous belt 15, enables the two stacking forks 3 to move synchronously and stably, thereby accurately completing the stacking and handling of goods. The lifting roller 10 and the stacking positioning rod 9 on the supporting platform 1 provide support and positioning for the movement of the stacking forks 3, ensuring the stability of the stacking process. The C-shaped fence 11 prevents goods from falling during the stacking process. The lifting mechanism, the push handle 12, and the casters 13 facilitate the movement and height adjustment of the equipment, improving the efficiency and flexibility of warehousing and logistics operations.

[0031] In this embodiment, the stacking motor 16 drives one of the stacking synchronous pulleys 14 to rotate. The stacking synchronous belt 15 causes the two stacking synchronous pulleys 14 to rotate synchronously, which in turn drives the two stacking screws 5 to rotate. Since the stacking screws 5 are threadedly engaged with the stacking threaded grooves 6 on the moving seat 4, and the moving seat 4 is positioned in the U-shaped groove 8 of the carrying platform 1 by the stacking positioning rod 9, the moving seat 4 will slide along the U-shaped groove 8, thereby driving the stacking fork 3 fixed on the moving seat 4 to move, realizing the stacking operation of goods. Under the action of the lifting mechanism, the carrying platform 1 can slide up and down in the fixed frame 2 to adjust the height to adapt to the stacking needs of goods of different heights. Pushing the handle 12 and the universal wheel 13 makes it convenient for the equipment to be moved to the designated position.

[0032] Furthermore, the lifting mechanism includes a fixed plate 17, two chains 18, and two rotating shafts 19. Each rotating shaft 19 is provided with two sprockets 20. The fixed plate 17 is bolted to the outside of the bearing platform 1. The fixed plate 17 is also bolted to the two chains 18. The two chains 18 are respectively engaged with the two sprockets 20 between the two rotating shafts 19. The two rotating shafts 19 are respectively rotatably disposed on the outside of the fixed frame 2 through bearings, and one of the rotating shafts 19 is driven by a power component.

[0033] In this embodiment, the lifting mechanism adopts a transmission method of chain 18 and sprocket 20, which is simple and reliable in structure and can stably realize the lifting of the bearing platform 1. The rotating shaft 19 is driven to rotate by the power component, which in turn drives the sprocket 20 and chain 18 to move, so that the fixed plate 17 fixed on the chain 18 drives the bearing platform 1 to rise or fall. This transmission method can withstand a large load and ensures the stability of the equipment when stacking goods of different weights.

[0034] In this embodiment, the power component drives one of the rotating shafts 19 to rotate, and the sprocket 20 on the rotating shaft 19 rotates accordingly, driving the chain 18 to move. Since the fixed plate 17 is fixed on the chain 18 and the bearing platform 1 is connected to the fixed plate 17, the movement of the chain 18 will cause the fixed plate 17 to drive the bearing platform 1 to slide up and down along the fixed frame 2, thereby realizing the lifting function of the bearing platform 1.

[0035] Furthermore, the lifting mechanism also includes a lifting positioning sleeve 21 and a lifting positioning rod 22. The lifting positioning sleeve 21 is fixedly mounted on the fixed plate 17, and the lifting positioning sleeve 21 is slidably mounted on the lifting positioning rod 22. The lifting positioning rod 22 is mounted on the outside of the fixed frame 2 through two U-shaped seats 35, and the rotating shaft 19 is located inside the U-shaped seats 35.

[0036] In this embodiment, the lifting positioning sleeve 21 and the lifting positioning rod 22 further improve the stability and accuracy of the lifting mechanism. The lifting positioning sleeve 21 slides on the lifting positioning rod 22, providing guidance for the lifting of the bearing platform 1, preventing the bearing platform 1 from deviating during the lifting process, ensuring the accuracy of the stacking operation, and improving the safety and reliability of the equipment.

[0037] In this embodiment, when the carrying platform 1 is lifted and lowered by the chain 18, the lifting positioning sleeve 21 fixed on the fixed plate 17 slides up and down along the lifting positioning rod 22 fixed on the outside of the fixed frame 2, which plays a guiding and positioning role, ensuring that the carrying platform 1 can only be lifted and lowered in the vertical direction and will not sway in the horizontal direction.

[0038] Furthermore, the power assembly includes a drive gear 23, a driven gear 24, a power shaft 25, and a power box 26. The drive gear 23 is rotatably mounted in the power box 26 via a power motor 27. The driven gear 24 is mounted on the power shaft 25, which is rotatably mounted in the power box 26. The drive gear 23 meshes with the driven gear 24. One of the rotating shafts 19 is connected to the power shaft 25 via two power synchronous pulleys 28 and a power synchronous belt 29. The power box 26 is mounted on the fixed frame 2.

[0039] In this embodiment, the power assembly achieves stable power transmission and speed change through the cooperation of the drive gear 23, driven gear 24, power shaft 25, power synchronous pulley 28, and power synchronous belt 29. The power motor 27 drives the drive gear 23 to rotate, and after speed change through the driven gear 24, the power is transmitted to the rotating shaft 19 through the power synchronous pulley 28 and power synchronous belt 29, which in turn drives the chain 18 of the lifting mechanism to move, so that the carrying platform 1 can be raised and lowered smoothly. This multi-stage transmission method can flexibly adjust the power transmission parameters according to actual needs, improving the adaptability and reliability of the equipment.

[0040] In this embodiment, the power motor 27 drives the drive gear 23 to rotate inside the power box 26. The drive gear 23 meshes with the driven gear 24, causing the driven gear 24 to drive the power shaft 25 to rotate. The power synchronous pulley 28 on the power shaft 25 is connected to the power synchronous pulley 28 on the rotating shaft 19 through the power synchronous belt 29, transmitting power to the rotating shaft 19. The rotating shaft 19 drives the sprocket 20 to rotate, thereby realizing the movement of the chain 18 and the lifting and lowering of the carrying platform 1.

[0041] Furthermore, the number of external teeth of the driving gear 23 is less than the number of external teeth of the driven gear 24, and the driving gear 23 is located to the side and below the driven gear 24.

[0042] In this embodiment, the design of the driving gear 23 having fewer external teeth than the driven gear 24 and the driving gear 23 being located below the driven gear 24 achieves the effect of speed reduction and torque increase. During power transmission, it can obtain a large torque output with a small power input, making it easier for the lifting mechanism to drive the lifting platform 1 to rise and fall. Especially when carrying heavy goods, this design can ensure the normal operation of the equipment and improve the load-bearing capacity and stability of the equipment.

[0043] In this embodiment, the power motor 27 drives the drive gear 23 to rotate. Since the drive gear 23 meshes with the driven gear 24, and the drive gear 23 has fewer external teeth while the driven gear 24 has more external teeth, according to the gear transmission principle, the driven gear 24 will rotate slower than the drive gear 23, but the torque will increase, thereby achieving the effect of deceleration and torque increase, and providing sufficient power for the lifting mechanism.

[0044] Furthermore, each of the four bottom corners of the fixing frame 2 has a maintenance threaded groove 30, and a maintenance support screw 31 is provided in the internal thread of the maintenance threaded groove 30. A rotating disk 32 is provided above the maintenance support screw 31, and a support foot 33 is provided below the maintenance support screw 31. Each of the four bottom corners of the fixing frame 2 is also provided with an auxiliary handle 34 for rotating the maintenance support screw 31.

[0045] In this embodiment, the maintenance support screw 31, support foot 33, and auxiliary handle 34 facilitate the fixing and adjustment of the equipment during maintenance. When the equipment needs maintenance, the maintenance support screw 31 can be unscrewed from the maintenance threaded groove 30, so that the support foot 33 contacts the ground, supporting the equipment and lifting the caster wheel 13 off the ground, ensuring the stability of the equipment during maintenance and preventing the equipment from moving. The auxiliary handle 34 makes it convenient for the operator to rotate the maintenance support screw 31, improving the convenience of maintenance operations.

[0046] In this embodiment, when the equipment needs maintenance, the operator holds the auxiliary handle 34 and rotates the maintenance support screw 31. The maintenance support screw 31 moves downward in the maintenance thread groove 30, so that the support foot 33 contacts the ground and gradually lifts the equipment until the caster wheel 13 leaves the ground. The equipment is then stably fixed, making it convenient for maintenance work. After the maintenance is completed, the maintenance support screw 31 is rotated in the opposite direction to make the support foot 33 leave the ground, and the equipment returns to a movable state.

[0047] Please see Figure 12 The present invention also provides a stacking method for a warehousing and logistics system, applied to the stacking equipment for the warehousing and logistics system described above, comprising the following steps: S1: Move the stacking equipment to the location of the goods to be stacked by flexibly moving the casters 13 under the fixed frame 2; S2: The drive gear 23 is driven by the power motor 27 to rotate, which in turn drives the driven gear 24 and the power shaft 25 to rotate. The drive synchronous pulley 28 and the drive synchronous belt 29 drive the rotating shaft 19 to rotate. The sprocket 20 on the rotating shaft 19 drives the chain 18 to move, which drives the fixed plate 17 and the carrying platform 1 to rise and fall, and adjusts the carrying platform 1 to a suitable height to receive goods. S3: Based on the stacking motor 16 driving the stacking synchronous wheel 14 and the stacking synchronous belt 15, the two stacking screws 5 are driven to rotate synchronously. The moving seat 4 slides along the U-shaped groove 8 under the drive of the stacking screws 5, and the two stacking forks 3 move with the moving seat 4 and insert into the bottom of the goods pallet. S4: Driven by the chain 18, the carrying platform 1 is raised and the stacking fork 3 lifts the pallet. Then, the two stacking screws 5 are controlled to move the stacking fork 3 onto the carrying platform 1. Finally, the goods are moved to the designated position by the stacking handle and the caster wheel 13. The goods are stacked according to the above operation. S5: After completing this stacking operation, based on the starting power component, the carrying platform 1 is lowered to the initial position, ready for the next stacking operation.

[0048] This invention discloses a stacking device for a warehousing and logistics system. The device can be easily and flexibly moved to the work position via the push handle 12 and the casters 13. In the power assembly, the power motor 27, through multi-stage transmission, enables the support platform 1 to rise and fall stably to adapt to different cargo heights. The lifting positioning sleeve 21 and the lifting positioning rod 22 cooperate to ensure precise and stable lifting. The stacking motor 16 drives the stacking synchronous wheel 14 and the stacking synchronous belt 15 to make the two stacking screws 5 rotate synchronously, thereby driving the moving seat 4 and the stacking fork 3 to move precisely to complete cargo stacking. The lifting roller 10 provides support for the movement of the stacking fork 3. The C-shaped guardrail 11 prevents cargo from falling. The maintenance support screw 31, support feet 33, and auxiliary handle 34 facilitate stable fixation during equipment maintenance. Overall, this improves the efficiency, accuracy, and safety of warehousing and logistics operations.

[0049] The above description discloses only one preferred embodiment of the present invention, and should not be construed as limiting the scope of the present invention. Those skilled in the art will understand that all or part of the processes of the above embodiments can be implemented, and equivalent changes made in accordance with the claims of the present invention are still within the scope of the invention.
