[0057] To enable those skilled in the art to more clearly understand this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0058] This application improves a cargo loading system that provides a more efficient, economical, and safe solution for cargo transfer from warehouse storage areas to loading operations and pallet A recycling.

[0059] This application provides a cargo loading system. Figure 1 The present application shows a schematic diagram of the structure of a cargo loading system according to one or more embodiments. Figure 2 It shows Figure 1 A top-down view diagram. Combined with... Figure 1 as well as Figure 2The cargo loading system includes a first conveying device 1, a de-palletizing conveying device 2, a de-palletizing device 3, a loading device 4, and a second conveying device 5. The first conveying device 1 is connected to a first storage area c1 for storing cargo boxes b and the de-palletizing conveying device 2. The cargo boxes b in the first storage area c1 are loaded onto pallets a. The cargo boxes b loaded on pallets a are conveyed via the first conveying device 1 and the de-palletizing conveying device 2 to the downstream end of the de-palletizing conveying device 2. The de-palletizing device 3 is located at the downstream end of the de-palletizing conveying device 2 to remove the pallets a used for loading cargo boxes b from the downstream end of the de-palletizing conveying device 2. The loading device 4 has a retractable support section. The support section of the loading device 4 carries the cargo boxes b after removing the pallets a and can be operably extended into a transport vehicle e to stack the cargo boxes b into the transport vehicle e. The second conveying device 5 is connected to the de-palletizing conveying device 2 and a second storage area c2 for storing pallets a to convey pallets a to the second storage area c2.

[0060] The cargo loading system provided in this application can transport cargo boxes b to a de-carrying device 3 via a first conveying device 1 and a de-carrying conveying device 2. The de-carrying device 3 can remove the pallet a loaded with cargo boxes b. The cargo boxes b with the pallet a removed are stacked into the transport vehicle e via a loading device 4. The removed pallet a is recycled to the second storage area c2 via a second conveying device 5. This achieves automated and mechanized cargo handling, improves operational efficiency, enhances the overall efficiency of logistics, and to a certain extent avoids safety risks to operators. It is an efficient, economical, and safe cargo handling method with great practicality.

[0061] The first storage area c1 is used to store cargo boxes b. Cargo boxes b are stacked onto pallet a. Pallet a and cargo boxes b stacked on pallet a can be transferred to the first conveying device 1 by means of forklifts, robotic arms or cargo robots.

[0062] Combination Figure 1 as well as Figure 2 The first conveying device 1 and the first storage area c1 can be connected by a first transfer conveying device 6. The height of the first transfer conveying device 6 is adjustable to accommodate the height difference between the first conveying device 1 and the first storage area c1, thereby improving the versatility of the equipment.

[0063] Figure 3 It shows Figure 2 A schematic diagram of the first transfer conveyor unit in the process. (Combined with...) Figure 3The two sides of the first transfer conveying device 6 in the width direction can be connected to two first transfer brackets 61 respectively. Each first transfer bracket 61 has at least two first transfer legs 611. The side of the first transfer conveying device 6 in the width direction can be vertically slidably connected to the first transfer legs 611 through the first transfer slider 62. In this way, according to the height of the first storage area c1, the first transfer slider 62 of the first transfer conveying device 6 can be controlled to slide to the corresponding height of the corresponding first transfer leg 611. Then, the first transfer slider 62 on the first transfer conveying device can be fixedly connected to the corresponding first transfer leg 611 by bolts, so that the height of the first transfer conveying device 6 can be adjusted to adapt to the height of the first storage area c1.

[0064] Combination Figure 3 To improve the stability of the first transfer bracket 61, the two first transfer legs 611 of each first transfer bracket 61 can be connected by at least one first transfer crossbeam 612. In some embodiments, the two first transfer legs 611 of each first transfer bracket 61 are connected by two first transfer crossbeams 612, which are respectively disposed between the top and bottom of the two first transfer legs 611. In other embodiments, the two first transfer legs 611 of each first transfer bracket 61 are connected by three or more first transfer crossbeams 612, which is not limited here.

[0065] In some embodiments, the first transfer conveyor 6 can be detachably disposed from the end of the first conveyor 1. In other embodiments, the first transfer conveyor 6 can be detachably connected to the end of the first conveyor 1 adjacent to it. When the equipment is in use, the first transfer conveyor 6 can be connected to the first conveyor 1 to improve the reliability of the conveying. When the equipment needs to be turned over, the first transfer conveyor 6 can be detached from the first conveyor 1 for easy turnover. In specific implementation, the sides of the ends of the first transfer conveyor 6 and the first conveyor 1 adjacent to each other can be connected by hooks or the like, which is not limited here.

[0066] Figure 4 It shows Figure 2 A schematic diagram of the derailment conveyor device. (Combined with...) Figure 4In some embodiments, the height of the towing conveyor 2 is also adjustable. The two ends of the first conveyor 1 are connected to the first transfer conveyor 6 and the towing conveyor 2 respectively, so that the conveying surfaces of the first conveyor 1 and the towing conveyor 2 are at the same height, thereby improving the versatility of the equipment. Specifically, two rows of adjustable-height towing support legs 21 can be provided at the bottom of the towing conveyor 2. These support legs 21 can be linear reciprocating mechanisms 115 such as hydraulic cylinders or ball screw pairs. By controlling the synchronous lifting and lowering of the two rows of support legs 21, the height of the towing conveyor 2 can be adjusted to match the height of the first conveyor 1, providing excellent versatility. Alternatively, the asynchronous lifting and lowering of the two rows of support legs 21 can be controlled to adjust the horizontal position of the top of the towing conveyor 2, adapting to uneven operating environments.

[0067] Combination Figure 1 as well as Figure 2 The side of the upstream end of the tractor-to-carryer 2 is connected to the end of the first conveyor 1. The cargo box b with pallet a is conveyed from the first conveyor 1 to the upstream end of the tractor-to-carryer 2, and then the cargo box b with pallet a is conveyed to the downstream end of the tractor-to-carryer 2 via the tractor-to-carryer 2.

[0068] Combination Figure 4 In some embodiments, the haulage conveyor 2 has two transport channels 22, meaning that two rows of cargo boxes b can be transported on the haulage conveyor 2 to improve transport efficiency. In specific implementation, a lifting and transferring device 7 is provided at the upstream end of the haulage conveyor 2. Two cargo boxes b with pallets a are successively transported to the lifting and transferring device 7 on the haulage conveyor 2 via the first conveyor 1. After being transferred by the lifting and transferring device 7, the two cargo boxes b with pallets a are successively transferred to the upstream end of the two transport channels 22 of the haulage conveyor 2, and then transported to the downstream end of the two transport channels 22 via the haulage conveyor 2.

[0069] When a container b with pallet a is conveyed to the downstream end of the unloading conveyor 2, pallet a needs to be removed before the container b can be loaded into the transport vehicle. Based on this, this application also provides an unloading device to remove pallet a to facilitate the loading of container b.

[0070] Figure 5 It shows Figure 2 The diagram shows the structure of the unloading device that carries cargo box b. Figure 6 It shows Figure 2 A schematic diagram of the structure of the removal device in the middle. Figure 7 It shows Figure 6 A structural diagram from another perspective. Combined with... Figures 5-7The tray removal device 3 includes a tray removal support frame 31, a drive mechanism 32, a first telescopic mechanism 33, a push plate 34, and a fork 35. The drive mechanism 32 is connected to the tray removal support frame 31 and has a rotatable output part. The push plate 34 is connected to the output part of the drive mechanism 32 through the first telescopic mechanism 33. The push plate 34 can move back and forth along the conveying direction perpendicular to the tray removal conveying device 2 under the drive of the first telescopic mechanism 33. The fork 35 is connected to the output part of the drive mechanism 32 and is located below the push plate 34. The fork 35 can be operably inserted into the corresponding hole of the tray b.

[0071] The towing device 3 provided in this application first controls the first telescopic mechanism 33 to move the fork 35 towards the cargo box b with the pallet a. The fork 35 is inserted into the insertion hole of the pallet a, and the pallet a and the cargo box b are supported by the fork 35. Then, the output part of the drive mechanism 32 is controlled to flip, so that the pallet a is above the cargo box b, and the cargo box b falls, separating the cargo box b from the pallet a. The cargo box b falls onto the support part of the loading device 4 for loading. Subsequently, the drive mechanism 32 is controlled to flip back to its original position, and the pallet a hanging on the fork 35 becomes upright. The pallet a is then transported and recovered by the second conveying device 5.

[0072] Combination Figures 5-7 The drag support frame 31 may include two drag brackets 311, which are arranged opposite each other along a conveying direction parallel to the drag conveying device 2. Each drag bracket 311 includes a connecting beam 3112 and two drag legs 3111, which are arranged opposite each other along a conveying direction perpendicular to the drag conveying device 2. The connecting beam 3112 is connected to the top of the two drag legs 3111, so that the drag support frame 311 forms a portal frame with good stability. Of course, to improve the stability of the drag support frame 311, a connecting beam 3112 may also be provided between the two drag legs 3111, which is not limited here.

[0073] Combination Figures 5-7 The drag support frame 31 may also include a drag crossbeam 312, the two ends of which are movably connected to the two drag supports 311 respectively, and the drag crossbeam 312 can move along the conveying direction perpendicular to the drag conveying device 2.

[0074] Combination Figures 5-7The dragging beam 312 can be movably mounted on the connecting beam 3112 of the dragging bracket 311 via the first gear and rack assembly 36. The first gear and rack assembly 36 may include a first drive motor 361, a first gear 362, and a first rack 363. The first drive motor 361 may be mounted at the end of the dragging beam 312, the first gear 362 may be mounted on the output shaft of the first drive motor 361, and the first rack 363 may be mounted on the connecting beam 3112 of the dragging bracket 311. Controlling the rotation of the first drive motor 361 drives the first gear 362 to rotate synchronously, so that the first gear 362 rotates on the corresponding first rack 363, thereby realizing the movable mounting of the dragging beam 312 on the dragging bracket 311. In other embodiments, the first drive motor 361 can be arranged on the connecting beam 3112 on the drag support 311, and the first rack 363 can be arranged on the drag beam 312, so that the drag beam 312 can be movably arranged on the drag support 311.

[0075] Combination Figures 5-7 In some embodiments, the first gear and rack assembly 36 can be provided on both connecting beams 3112 on the towing bracket 311. The two first gear and rack assemblies 36 work synchronously to drive the towing crossbeam 312 to move back and forth on the connecting beam 3112 on the towing bracket 311. In other embodiments, the first gear and rack assembly 36 can be provided on one connecting beam 3112 on the towing bracket 311. The end of the other connecting beam 3112 and the towing crossbeam 312 can have sliding friction or rolling friction. The towing crossbeam 312 can also be driven to move back and forth on the connecting beam 3112 on the towing bracket 311 by the operation of one first gear and rack assembly 36.

[0076] It should be noted that the drag beam 312 can also move back and forth on the connecting beam 3112 on the drag bracket 311 through a linear reciprocating mechanism such as a ball screw or linear guide rail, and there is no limitation on this.

[0077] Combination Figures 5-7The towing device 3 may also include a connecting component 37, through which the drive mechanism 32 is connected to the towing beam 312. The connecting component 37 can move back and forth on the towing beam 312. In a specific implementation, the connecting component 37 is movably mounted on the towing beam 312 via a second gear and rack assembly 38. The second gear and rack assembly 38 may include a second drive motor 381, a second gear (not shown in the figure), and a second rack 382. The second drive motor 381 may be located at the top of the connecting component 37, the second gear is located on the output shaft of the second drive motor 381, and the second rack 382 is arranged on the towing beam 312. Controlling the rotation of the second drive motor 381 drives the second gear to rotate synchronously, so that the second gear rotates on the corresponding second rack 382, ​​thereby achieving the movable mounting of the connecting component 37 on the towing beam 312. In other embodiments, the second drive motor 381 can be arranged on the drag beam 312 and the second rack 382 can be arranged on the connecting component 37, which can also realize the movable arrangement of the drag beam 312 on the drag bracket 311.

[0078] Combination Figures 5-7 The connecting component 37 may include two opposing guide rails 371, both of which are vertically arranged. A drive mechanism 32 is connected between the two guide rails 371. Both guide rails 371 are equipped with the aforementioned second gear and rack assembly 38. The two second gear and rack assemblies 38 work synchronously to drive the two guide rails 371 to move back and forth synchronously on the drag beam 312. In other embodiments, one guide rail 371 of the connecting component 37 may be equipped with the aforementioned second gear and rack assembly 38, and the other guide rail 371 and the drag beam 312 may have sliding friction or rolling friction. The connecting component 37 may also move back and forth on the drag beam 312 by the operation of one second gear and rack assembly 38.

[0079] It should be noted that the connecting component 37 can also achieve its reciprocating movement on the drag beam 312 through linear reciprocating mechanisms such as ball screws and linear guides, and there are no restrictions on this.

[0080] Combination Figures 5-7 The drive mechanism 32 can move vertically back and forth on the guide rail 371. In a specific implementation, a ball screw mechanism 310 can be installed in the guide rail 371. The drive mechanism 32 is connected to the output part of the ball screw mechanism 310. By controlling the action of the ball screw mechanism 310, the drive mechanism 32 is driven to move vertically back and forth on the guide rail 371.

[0081] Combination Figure 5 as well as Figure 7Each guide rail 371 can be equipped with a ball screw mechanism 310. The synchronous operation of the ball screw mechanisms 310 in the two guide rails 371 can cause the drive mechanism 32 to move back and forth vertically. In other embodiments, a ball screw mechanism 310 can be provided in one guide rail 371, and the other guide rail 371 and the drive mechanism 32 can have sliding friction or rolling friction. The operation of one ball screw mechanism can also drive the drive mechanism 32 to move back and forth on the guide rail 371.

[0082] Similarly, it should be noted that the drive mechanism 32 can also achieve its reciprocating movement on the guide rail 371 through linear reciprocating mechanisms such as gear and rack assemblies and linear guide rails, without any restrictions.

[0083] With the above settings, the drive mechanism 32 can move horizontally, vertically, and in a way that adapts to different working conditions and operating conditions.

[0084] In some embodiments, the drive mechanism 32 can be a rotary motor, which is installed in a rotating base. The rotating base can move vertically back and forth on the guide rail 371 to drive the rotary motor to move vertically back and forth.

[0085] Combination Figures 5-7 The towing device 3 may further include a support bracket 39, which is connected to the output of the drive mechanism 32. The support bracket 39 can rotate under the drive of the drive mechanism 32. A fork 35 is disposed at the bottom of the support bracket 39, and a push plate 34 is connected to the support bracket 39 via a first telescopic mechanism 33. Since the drive mechanism 32 moves horizontally, vertically, and laterally, the support bracket 39, fork 35, and push plate 34 disposed on the output of the drive mechanism 32 can also move horizontally, vertically, and laterally, and can rotate under the drive of the drive mechanism 32. In some embodiments, the fork 35 can be integrally formed and connected or welded to the support bracket 39. The first telescopic mechanism 33 can be a scissor fork structure, or a drive mechanism such as a motor can be used, without limitation.

[0086] Combination Figures 5-7 The towing device 3 may also include a clamping plate 391, which is connected to the top of the support bracket 39 and located above the push plate 34. When the output of the drive mechanism 32 flips, the clamping plate 391 rotates to the bottom, and the cargo box b can fall onto the clamping plate 391.

[0087] Figure 8 A schematic diagram showing the assembly of the clamping plate on the support bracket is provided. Figures 5-8In some embodiments, the clamping plate 391 can move relative to the fork 35, that is, the distance between the clamping plate 391 and the fork 35 is adjustable. Depending on the thickness of the cargo box b and the pallet a on which the cargo box b is loaded, the clamping plate 391 can move relative to the fork 35 to adjust the distance between the clamping plate 391 and the fork 35, so that the clamping plate 391 clamps the cargo box b and prevents the cargo box b from falling off during the flipping process. In addition, it can also adapt to the towing of cargo boxes of different sizes, and has good practicality.

[0088] Combination Figure 8 In specific implementation, a telescopic component 393 can be installed on the top of the support bracket 39. The telescopic end of the telescopic component 393 can extend and retract vertically, and the output end of the telescopic component 393 is connected to the clamping plate 391. That is, the movement of the telescopic component 393 is controlled according to the thickness of the cargo box b and the pallet a on which the cargo box b is loaded, so that the clamping plate 391 can move relative to the fork 35 to adjust the distance between the clamping plate 391 and the fork 35, so that the clamping plate 391 clamps the cargo box b, preventing the cargo box b from falling off during the flipping process. In addition, it can also adapt to the towing of cargo boxes of different specifications, and has good practicality. The telescopic component 393 can be a linear guide rail, or other types of linear reciprocating mechanisms, such as ball screws, etc., which are not limited here.

[0089] Combination Figures 5-7 The towing device 3 may further include a protective plate 392, which is connected to at least one side of the support bracket 39. During the flipping process of the output of the drive mechanism 32, the protective plate 392 can support the cargo box b, preventing it from being thrown to other positions before it is fully flipped. After flipping, the cargo box b is clamped onto the clamping plate 391 under the guidance of the protective plate 392. In some embodiments, the protective plate 392 may be disposed on one side of the support bracket 39, and the protective plate 392 may be connected together with the clamping plate 391, both of which are connected to the support bracket 39. In other embodiments, the protective plate 392 may also be disposed on both sides of the support bracket 39, without limitation.

[0090] Combination Figures 5-7 The working process of the dragging device 3 is as follows:

[0091] When the cargo box b loaded on pallet a is transported to the downstream end of the hauling conveyor 2, the transport stops and the first telescopic mechanism 33 is controlled to move, driving the fork 35 to move towards the cargo box b with pallet a. The fork 35 is inserted into the socket of pallet a, and pallet a and cargo box b are carried by the fork 35.

[0092] S2 controls the drive mechanism 32 to rise along the guide rail 371 to a suitable height to lift the box b with pallet a, so that the distance between the bottom of pallet a and the downstream end of the towing conveyor 2 is not less than the overall height of pallet a and box b, so that pallet a and box b have enough space to flip.

[0093] S3 controls the output of drive mechanism 32 to flip, so that pallet a is above box b, box b falls onto clamping plate 391, pallet a is suspended on fork 35 to achieve dragging of box b. During the flipping process of box b, guard plate 392 can support box b and prevent box b from being thrown to other positions before flipping into place.

[0094] S4 controls the first telescopic mechanism 33 to continue operating, and push plate 34 pushes the cargo box b to detach from the clamping plate 391. The cargo box b falls to the downstream end of the haulage conveyor 2, ready for the loading device to operate.

[0095] S5 controls the output of drive mechanism 32 to flip back to its original position, so that tray a is placed upright.

[0096] S6 controls the drive mechanism 32 to move along the conveying direction parallel to the towing conveyor 2 to above the second conveyor 5;

[0097] S7 controls the drive mechanism 32 to descend along the guide rail 371, causing the pallet a to fall onto the second conveying device 5;

[0098] S8 controls the first telescopic mechanism 33 to return to its original position, the fork 35 separates from the pallet a, the pallet a is supported by the second conveying device 5, and the pallet a is transported and recovered by the second conveying device 5.

[0099] Combination Figure 1 as well as Figure 2 Two towing devices 3 can be set up, and the two towing devices 3 are set up opposite each other along the conveying direction perpendicular to the towing conveyor 2. On the one hand, the towing operation of two cargo boxes b can be completed at the same time to improve the towing efficiency and loading efficiency. On the other hand, in the execution steps S4 and S7, the drive mechanism 32 of the two towing devices 3 can also be controlled to move relative to each other on the towing support 311 along the conveying direction perpendicular to the towing conveyor 2, so that the two cargo boxes b or pallets a are abutted together. At this time, it can be determined that the cargo box b or pallet a has been delivered to the correct position, without the need to set up a sensor to sense whether the delivery has been completed, which has good practicality.

[0100] Figure 9 It shows Figure 2 A schematic diagram of the loading device in the diagram. (Combined with...) Figure 9The loading device 4 can be a retractable truss mechanism, with its support having at least a two-section retractable structure, allowing the cargo box b to be loaded and inserted into the deepest part of the transport vehicle e for operation. Two rows of lifting mechanisms 41 are provided at the bottom of the loading device 4. These lifting mechanisms 41 can be hydraulic cylinders or linear reciprocating mechanisms 115 such as ball screw pairs. The synchronous movement of the lifting mechanisms 41 enables the lifting and lowering of the loading device 4, facilitating the handling of high-level cargo on the pallet truck. Alternatively, the asynchronous lifting and lowering of the lifting mechanisms 41 can be controlled to adjust the horizontal position of the device, adapting to uneven ground conditions.

[0101] Figure 10 It shows Figure 9 The structural diagram of the loading mechanism in the diagram, combined with Figure 9 as well as Figure 10 The loading device 4 may be equipped with a loading mechanism 42 on its support. The loading mechanism 42 may include a vertical guide rail 421, a horizontal guide rail 422, a second telescopic mechanism 423, and a fork 424. There are two vertical guide rails 421, which are set on the support of the loading device 4. The horizontal guide rail 422 is slidably connected to the two vertical guide rails 421. Each vertical guide rail 421 may be equipped with a ball screw pair. The horizontal guide rail 422 is connected to the output of the ball screw pair so that the horizontal guide rail 422 can be raised and lowered by controlling the movement of the ball screw pair. The second conveying mechanism may be a scissor fork structure, which can move laterally on the horizontal guide rail 422. The fork 424 is set on the telescopic end of the second conveying mechanism, that is, the fork 424 can move vertically, laterally, and longitudinally. The fork 424 is used to support the cargo box b.

[0102] Combination Figure 9 as well as Figure 10 The loading device 4 works as follows: After the cargo box b falls to the downstream end of the towing conveyor 2, the towing conveyor 2 is also equipped with a lifting and transferring device 7. The lifting and transferring device 7 lifts the cargo box b, and the forks 424 of the loading device 4 are controlled to move to the bottom of the cargo box b and lift it. Then, the support part of the loading device 4 extends into the loading position inside the transport vehicle e. By controlling the forks 424 to move vertically, laterally, and longitudinally, the cargo box b is stacked into the transport vehicle e, thus realizing the loading operation of the cargo box b inside the transport vehicle e. While the loading device 4 is performing the loading operation, the goods on the rear conveyor line continue to be transported, and the towing device 3 continues to perform the unloading operation of the cargo box b to complete the loading operation of the transport vehicle e.

[0103] Combination Figure 1 as well as Figure 2With two removal devices 3, two removal conveying devices 2 can also be arranged in parallel. The first conveying device 1 is connected to the input ends of the two removal conveying devices 2 in sequence. The middle part of the second conveying device 5 is connected to the downstream end of the end of the removal conveying device 2. The two removal brackets 311 of the removal device 3 can be arranged opposite each other on both sides of the width direction of the second conveying device 5. One end of the second conveying device 5 is connected to the second storage area c2. The other end of the second conveying device 5 is connected to the second storage area c2. A conveying track d is provided between the second end of the second conveying device 5 and the second storage area c2. A conveying vehicle is provided on the conveying track d. The pallet a removed by one removal device 3 is conveyed to the second storage area c2 through the second conveying device 5. The pallet a removed by the other removal device 3 is conveyed to the second storage area c2 through the second conveying device 5 and the transport vehicle 9. In this way, the pallets a removed by the two removal devices 3 can be transported to the same location (second storage area c2) for recycling through the second conveying device 5 and the transport vehicle 9, which is more convenient and practical.

[0104] Combination Figure 1 as well as Figure 2 In some embodiments, the second conveying device 5 and the second storage area c2 are connected by a second transfer conveying device 8. The height of the second transfer conveying device 8 is adjustable. Both ends of the second conveying device 5 are connected to the second transfer conveying device 8 and the towing conveying device 2, respectively, to accommodate the height difference between the second conveying device 5 and the second storage area c2, thereby improving the versatility of the equipment.

[0105] Figure 11 It shows Figure 2 A schematic diagram of the second transfer conveyor unit in the diagram. (Combined with...) Figure 11 The two sides of the second transfer conveying device 8 in the width direction can be connected to two second transfer brackets 81 respectively. Each second transfer bracket 81 has at least two second transfer legs 82. The side of the second transfer conveying device 8 in the width direction can be slidably connected to the second transfer legs 82 in the vertical direction through the second transfer slider 83. In this way, according to the height of the second storage area c2, the second transfer slider 83 of the second transfer conveying device 8 can be controlled to slide to the corresponding height of the corresponding second transfer leg 82. Then, the second transfer slider 83 on the second transfer conveying device 8 can be fixedly connected to the corresponding second transfer leg 82 by bolts, so that the height of the second transfer device can be adjusted to adapt to the height of the second storage area c2.

[0106] Combination Figure 11To improve the stability of the second transfer bracket 81, the two second transfer legs 82 of each second transfer bracket 81 can be connected by at least one second transfer crossbeam 812. In some embodiments, the two second transfer legs 82 of each second transfer bracket 81 are connected by two second transfer crossbeams 812, which are respectively disposed between the top and bottom of the two second transfer legs 82. In other embodiments, the two second transfer legs 82 of each second transfer bracket 81 are connected by three or more second transfer crossbeams 812, which is not limited here.

[0107] In some embodiments, the second transfer device can be detachably disposed from the end of the second conveying device 5. In other embodiments, the ends of the second transfer device 8 and the second conveying device 5 adjacent to each other can be detachably connected. When the equipment is in use, the two are connected together to improve the reliability of the conveying; when the equipment needs to be turned over, the two can be disassembled for easy turnover. In specific implementation, the sides of the ends of the second transfer conveying device 8 and the second conveying device 5 adjacent to each other can be connected by hooks or the like, which is not limited here.

[0108] In some embodiments, the transport vehicle 9 can be an RGV vehicle, whose transport track d can cross the bottom of the towing transport device 2 to save space and has good practicality.

[0109] Combination Figure 1 as well as Figure 2 In some embodiments, the cargo loading system may further include a third conveying device 10, with the other end of the second conveying device 5 connected to the conveying track d via the third conveying device 10. The pallet a removed by the towing device 3 is transferred to the transport vehicle 9 via the second conveying device 5 and the third conveying device 10 in sequence, and then transported to the second storage area c2 for recycling via the transport vehicle 9.

[0110] In related technologies, if the required goods include scattered items in the final batch, it is necessary to dismantle cargo box b to pick up the appropriate quantity of goods. In this case, manual labor would cause unnecessary manpower burden and affect the loading cycle of goods.

[0111] Based on this, combined Figure 1 as well as Figure 2The cargo loading system of this application may further include a fourth conveying device 12 and a depalletizing device 11, wherein: one end of the third conveying device 10 is connected to the other end of the second conveying device 5, the middle part of the third conveying device 10 is connected to the conveying track d and the fourth conveying device 12 in sequence, the third conveying device 10 and the fourth conveying device 12 are sequentially moved away from the second conveying device 5, the fourth conveying device 12 is connected to the decoupling conveyor 2, and the depalletizing device 11 is set at the other end of the third conveying device 10 to remove part of the cargo in the cargo box b. In specific implementation, after the cargo in the cargo box b is removed by the depalletizing device 11, the box is sealed. The cargo box b loaded on the pallet a is sequentially transported to the downstream end of the decoupling conveyor 2 by the fourth conveying device 12, the third conveying device 10, and the decoupling conveyor 2. After the decoupling device 3 removes the pallet a, the cargo box b is transferred to the transport vehicle e by the loading device 4, and the removed pallet a is recycled.

[0112] Figure 12 It shows Figure 2 A schematic diagram of the depalletizing and palletizing device. (Combined with...) Figure 12 The depalletizing device 11 includes a depalletizing support frame 111 and a clamp 112. The clamp 112 can move vertically, horizontally, and longitudinally on the depalletizing support frame 111, thereby removing goods loaded in different positions in the cargo box b from the cargo box b.

[0113] Combination Figure 11 In specific implementation, the top of the palletizing support frame 111 is provided with two sets of support parts, each set of support parts including two support rails 113. The support rails 113 are arranged parallel to the conveying direction of the fourth conveying device 12. The support rails 113 can be movably arranged on the top of the palletizing support frame along the conveying direction perpendicular to the fourth conveying device 12. The clamps 112 are connected to each set of support rails 113 through clamp mounting seats 114. The clamp mounting seats 114 can be arranged parallel to the conveying direction of the fourth conveying device 12. The clamp is movably connected to two support rails 113. A linear reciprocating mechanism 115 is provided on the clamp mounting base 114. The linear reciprocating mechanism 115 can be a linear guide rail or the like. The clamp 112 is set on the output part of the linear reciprocating mechanism 115, which can realize the movement of the clamp 112 in the vertical, horizontal and longitudinal directions. This facilitates the removal of goods loaded in different positions in the cargo box b from the cargo box b, thereby reducing the burden on the operators and not affecting the loading rhythm of the goods. It has good adaptability.

[0114] Combination Figure 1 as well as Figure 2In some embodiments, the first storage area c1 and the second storage area c2 can be different storage areas of the platform c, that is, the first storage area c1 and the second storage area c2 are both located on the same side, so as to improve the automation and mechanization of loading and unloading operations of the platform c, thereby improving the operational efficiency of the platform c and improving the overall logistics efficiency, and also reducing the safety risks of operators.
