Description

Technical Field

[0001] This invention relates to the field of palletizing technology, specifically to a palletizing and stacking device and method for palletizing and stacking palletized boxed goods. Background Technology

[0002] When loading full pallets of goods, limitations imposed by vehicle height and load capacity prevent the vertical stacking from being exact multiples of the factory-manufactured pallet height. The height of the last pallet must be adjusted to match the vehicle's height and allowable load. Currently, depalletizing often requires manual intervention or the use of multiple machines, resulting in a complex process that fails to achieve efficient and seamless integrated pallet removal and depalletizing. In particular, existing equipment lacks flexible and adjustable solutions for depalletizing different layers. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a palletized and stacked cargo removal and stacking device and method. By integrating a flipping frame, clamping mechanism, clamping support beam, and stacking drive mechanism, the entire process of clamping, flipping, removing pallets, and stacking cargo is completed continuously on a single device. This reduces manual intervention, integrates multiple discrete processes into a coherent automated process, significantly improves operational efficiency, and reduces labor intensity and labor costs.

[0004] To address the aforementioned technical problems, this invention provides a palletizing and stacking device for palletized goods, comprising a chassis, a tilting drive system and a tilting frame mounted on the chassis, the tilting frame being rotatably connected to the chassis, the tilting drive system for tilting the tilting frame by 90°, two sets of clamping beams arranged opposite each other on the tilting frame, the two sets of clamping beams being movable relative to each other to clamp the goods, the clamping beams comprising multiple parallel crossbeams, the crossbeams being slidably mounted on the tilting frame, adjacent crossbeams being connected by locking members, the locking members being able to release the connection between adjacent crossbeams, and a stacking drive mechanism mounted on the tilting frame, the stacking drive mechanism being connected to the topmost crossbeam for controlling the movement of the topmost crossbeam.

[0005] In some embodiments, the clamping support beam includes a plurality of hooks, each hook corresponding to a crossbeam, one end of the hook being connected to the corresponding crossbeam, and the other end of the hook being connected to an adjacent crossbeam below the crossbeam via a locking element.

[0006] In some embodiments, the locking member includes a pull rod slidably connected to a crossbeam. The pull rod is provided with a first limiting member, a second limiting member, and a locking block. The locking member is used to cooperate with a hook to connect two adjacent crossbeams. The first limiting member and the second limiting member cooperate with both ends of the crossbeam to limit the sliding range of the pull rod. When the first limiting member abuts against the crossbeam, the locking member connects two adjacent crossbeams. When the second limiting member abuts against the crossbeam, the locking member disengages from the hook, and the connection between the two adjacent crossbeams is released.

[0007] In some embodiments, the crossbeam is a tubular structure, the pull rod is slidably arranged inside the crossbeam, and both ends of the pull rod extend out of the crossbeam. The first limiting member and the second limiting member are respectively arranged at the two ends of the pull rod extending out of the crossbeam. The locking block is located inside the crossbeam. The top and bottom surfaces of the crossbeam are symmetrically provided with through holes. One end of the hook passes through the through hole on the bottom surface of the corresponding crossbeam and the through hole on the top surface of the adjacent crossbeam below the corresponding crossbeam in sequence, and cooperates with the locking block.

[0008] In some embodiments, the clamping support beam includes lifting lugs, with two lifting lugs corresponding to the through holes on the top surface of each beam. One end of the lifting lug is hung at the through hole on the top surface of the beam, and the other end of the lifting lug is connected to a hook.

[0009] In some embodiments, the portion of the lifting lug located inside the crossbeam has a sliding groove, and the locking block of the pull rod is slidably disposed on the sliding groove. When the second limiting member abuts against the crossbeam, the locking member disengages from the hook, and the locking member is located on the sliding groove of one of the lifting lugs.

[0010] In some embodiments, a support block is provided on the bottom crossbeam, and a support rod is provided on the tilting frame, with the support block pressing on the support rod.

[0011] In some embodiments, the tilting frame includes a tilting arm, which includes a horizontal arm and a vertical arm. One end of the horizontal arm is fixedly connected to the vertical arm and hinged to the chassis. A clamping arm is slidably disposed at the other end of the horizontal arm. The clamping arm is parallel to the vertical arm. A support platform is slidably disposed on the horizontal arm. A clamping drive mechanism is disposed on the horizontal arm. The clamping drive mechanism is used to drive the clamping arm to move perpendicular to the vertical arm.

[0012] In some embodiments, the chassis is provided with casters, a traction plate is provided at one end of the chassis, and support mechanisms are provided at the four corners of the chassis.

[0013] On the other hand, the present invention provides a method for palletizing and stacking goods using the aforementioned palletized box unpalletizing and stacking device, comprising: The forklift places a palletized stack of goods onto the tilting frame, and the clamping beams clamp the stack of goods. The tilting drive system tilts the tilting frame 90°. The stacking drive mechanism drives the clamping beam to move, so that the entire stack of goods is separated from the pallet and the pallet is replaced by a bottom sliding plate. Based on the required number of layers of goods in a single stack, operate the locking mechanism of the corresponding beam to release the connection between the corresponding beam and the adjacent beam. The stacking drive mechanism drives the crossbeam to move to achieve stacking of the entire stack of goods, and inserts layered sliding plates between adjacent single stacks of goods; The tilting drive system tilts the tilting frame back to its original position, clamps the support beams, and releases the goods. Forklifts transfer single stacks of goods.

[0014] The beneficial effects of this invention are as follows: 1. This invention integrates a flipping frame, a clamping mechanism, a clamping support beam, and a stacking drive mechanism to continuously complete the entire process of clamping, flipping, removing pallets, and stacking goods on a single device. This reduces manual intervention, integrates multiple discrete processes into a coherent automated process, significantly improves operational efficiency, and reduces labor intensity and labor costs.

[0015] 2. This invention, through its unique clamping beam and locking mechanism design, allows operators to freely select the number of layers and portions of goods to be stacked according to actual needs (such as vehicle load capacity, warehouse space, and order quantity). By operating the locking mechanism of a specific beam, it is possible to precisely control which beams participate in the lifting, thereby accurately dividing the entire stack of goods into two or more independent single stacks.

[0016] 3. The present invention enables multiple crossbeams to move together or separate quickly through the coordinated design of pull rods, locking blocks, lifting lugs and hooks.

[0017] 4. The lifting lug of the present invention is used to connect the hook so that two adjacent crossbeams can be connected, and also to provide support and a groove for the tie rod so that the tie rod can slide stably in the crossbeam. Attached Figure Description

Detailed Implementation

[0020] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0021] like Figure 1 As shown, the present invention provides a palletized and stacked goods unpalletizing and stacking device, including a chassis 1, a flipping frame 2, a clamping beam 3, and a locking component. The flipping frame 2 is rotatably mounted on the chassis 1 and is used to place and flip the goods. The clamping beam 3 is mounted on the flipping frame 2 and is used to clamp the goods. A stacking drive mechanism 28 is provided on the clamping beam 3. The stacking drive mechanism 28 and the locking component cooperate with the clamping beam 3 to unpalletize and stack the goods.

[0022] like Figure 2 As shown, the chassis 1 is composed of a steel frame structure. Universal wheels 11 and support mechanisms 13 are installed at the four corners of the chassis 1. The universal wheels 11 facilitate the movement of the chassis 1, and the height of the support mechanism 13 is adjustable, allowing the universal wheels 11 to be raised. The chassis 1 is stably supported solely by the support mechanism 13. A towing plate 12 is installed at one end of the chassis 1, which can be connected to a towing forklift or other powered vehicle. A tilting drive system 14 is installed on the chassis 1. The tilting drive system 14 includes an electrical control box 141 and a hydraulic system 142, which includes hydraulic rods.

[0023] like Figure 3 As shown, the tilting frame 2 includes a tilting arm 21, a clamping arm 22, and a support platform 23. The tilting arm 21 includes a horizontal arm 211 and a vertical arm 212, which are arranged vertically. One end of the horizontal arm 211 is fixedly connected to the vertical arm 212, and a mounting base 27 is rotatably mounted on one end of the horizontal arm 211. The horizontal arm 211 is mounted on the chassis 1 via the mounting base 27. The clamping arm 22 is slidably mounted on the other end of the horizontal arm 211, and the clamping arm 22 is parallel to the vertical arm 212. A clamping drive mechanism is provided on the horizontal arm 211, such as... Figure 4 As shown, the clamping drive mechanism includes an electric push rod 26, a linear guide rail 25 is provided on the horizontal arm 211, and the clamping arm 22 is slidably connected to the horizontal arm 211 through the linear guide rail 25. The electric push rod 26 is used to drive the clamping arm 22 to move perpendicular to the vertical arm 212, thereby clamping the goods. A support platform 23 is slidably provided on the upper surface of the horizontal arm 211, and the goods can be placed on the support platform 23. As the clamping arm 22 is pushed, the goods slide towards the vertical arm 212 through the support platform 23 until they are pressed against the vertical arm 212.

[0024] like Figure 3 As shown, a slide rail and multiple sliders are provided on the opposite side of the vertical arm 212 and the clamping arm 22. Both the vertical arm 212 and the clamping arm 22 are provided with a support rod 24 and a stacking drive mechanism 28. The support rod 24 is located below the stacking drive mechanism 28. The support rod 24 is used to support the clamping beam 3. The stacking drive mechanism 28 is used to drive the clamping beam 3 to move in a direction parallel to the clamping arm 22.

[0025] like Figure 5 As shown, the clamping support beam 3 includes multiple parallel crossbeams 31. The crossbeams 31 are connected to the slider, allowing the crossbeams 31 to slide freely up and down on the vertical arm 212 and the clamping arm 22. Adjacent crossbeams 31 are connected by locking members. A connecting seat 39 is provided on the topmost crossbeam 31, which is connected to the stacking drive mechanism 28. A support block 38 is provided on the bottommost crossbeam 31, which is supported on the support rod 24.

[0026] like Figure 6 As shown, a pressure pad is provided on one side of the crossbeam 31. The surface of the pressure pad that contacts the goods has a toothed structure, and the pressure pad can be made of rubber material.

[0027] like Figure 7 As shown, the crossbeam 31 has a square tubular structure. Symmetrical through holes are opened on both the top and bottom surfaces of the crossbeam 31 near both ends. Two symmetrical lifting lugs 32 are installed on the through holes on the top surface of the crossbeam 31. Figure 10 As shown, the lifting lug 32 is L-shaped, with one end of the lug 32 hanging on the top surface of the crossbeam 31. A groove 321 is provided on the upper part of the lug 32, as shown... Figure 9 As shown, the hook 33 is fixedly connected to the lifting lug 32 by bolts, as... Figure 10 As shown, a hook groove 331 is provided on the hook 33, and the lower end of the hook 33 extends into the adjacent crossbeam 31 below. The hook groove 331 of the hook 33 is flush with the sliding groove 321 of the lifting lug 32 of the crossbeam 31 below it.

[0028] like Figure 8 As shown, the locking component includes a pull rod 34, which comprises four rods forming a rectangular frame. Two locking blocks 35 are fixedly mounted on one of the longer rods. A first limiting member 36 and a second limiting member 37 are positioned between the two longer rods. The first limiting member 36 and the second limiting member 37 are located near both ends of the pull rod 34, respectively. Both the first limiting member 36 and the second limiting member 37 are rod-shaped structures. Figure 7 As shown, the middle part of the pull rod 34 and the two locking blocks 35 are located inside the crossbeam 31, while the first limiting member 36 and the second limiting member 37 are located outside the crossbeam 31. Figure 7 , 11 As shown, when the first limiting member 36 abuts against one end of the crossbeam 31, the second limiting member 37 has a certain distance from the other end of the crossbeam 31. At this time, the two locking blocks 35 are located at the through holes at both ends of the crossbeam 31, and the locking blocks 35 are simultaneously inserted into the sliding groove 321 of the lifting lug 32 and the hook groove 331 of the hook 33. Since the locking blocks 35 are inserted into the hook groove 331, the upper crossbeam 31 hooks the lower crossbeam 31 through the hook 33, thereby realizing the connection between the two adjacent crossbeams 31. When unlocking is required, the pull rod 34 is moved so that the second limiting member 37 abuts against the crossbeam 31. The locking block 35 moves out of the hook groove 331 but remains in the sliding groove 321 of one of the lifting lugs 32, allowing the lifting lug 32 to support the pull rod 34 and prevent it from falling. At this time, the hook 33 of the upper crossbeam 31 can be pulled out from between the two lifting lugs 32 of the lower crossbeam 31, thereby releasing the connection between the two adjacent crossbeams 31. Therefore, the lifting lugs of the present invention are used both to connect the hooks, enabling the connection between two adjacent crossbeams, and to provide support and a sliding groove for the pull rod, allowing the pull rod to slide stably in the crossbeam.

[0029] like Figure 12 As shown, the palletizing and stacking method using this palletized box cargo unpalletizing and stacking device includes: S1. The forklift places the palletized stack of goods on the platform 23 of the tilting frame 2. The electric push rod 26 pulls the clamping arm 22, so that the clamping arm 22 moves closer to the vertical arm 212. The vertical arm 212 and the clamping arm 22 gradually clamp the entire stack of goods.

[0030] S2, the hydraulic rod of the hydraulic system 142 extends, rotating the tilting frame 2 90° around the mounting base 27.

[0031] S3, the stacking drive mechanism 28 drives the two clamping beams 3 to move simultaneously away from the support platform 23, so that the entire stack of goods is separated from the pallet, and the pallet is replaced by the bottom sliding plate, thus completing the pallet removal.

[0032] S4. Based on the required number of layers in a single stack of goods, operate the locking mechanism of the corresponding crossbeam 31 to release the connection between the corresponding crossbeam 31 and the adjacent crossbeam 31; the stacking drive mechanism 28 drives part of the crossbeam 31 to move and realize the stacking of the entire stack of goods, and inserts a layering slide plate between adjacent single stacks of goods; for example, when the height of the last pallet of goods cannot be loaded into the vehicle or the vehicle's load capacity is limited and needs to be reduced, the number of layers to be stacked can be confirmed first, and then the corresponding pull rod 34 can be moved, and the stacking drive mechanism 28 drives part of the crossbeam 31 to divide the entire stack of goods into two single stacks of goods, and the layering slide plate between the two single stacks of goods can complete the stacking.

[0033] Of course, the present invention can divide the entire stack of goods into any number of parts. For example, if the entire stack of goods is to be divided into three single stacks of goods, the number of layers of the lower single stack of goods is determined, the corresponding pull rod 34 is moved, and the stacking drive mechanism 28 drives part of the crossbeam 31, so that the lower single stack of goods is separated from other goods. A layered sliding plate is placed between the lower single stack of goods and other goods. Then, the number of layers of the middle single stack of goods is determined, the corresponding pull rod 34 is moved, and the stacking drive mechanism 28 drives part of the crossbeam 31 again, so that the middle single stack of goods is separated from the upper single stack of goods. A layered sliding plate is placed between the middle single stack of goods and the upper goods, thereby completing the stacking. Figure 12 The image only illustrates the case where a whole stack of goods is divided into two parts.

[0034] S5. Finally, the tilting drive system 14 tilts the tilting frame 2 back to its original position, clamps the support beam 3 and releases the goods; a forklift equipped with a push-pull attachment transfers the goods out via a slide plate, and the slide plate is removed after the goods are stacked.

[0035] The aforementioned movement of the lever 34 can be performed manually or automatically by a mechanized system.

[0036] The above-described embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
