[0023] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0024] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0025] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0026] like Figure 1 As shown, a stacking system of an embodiment includes a palletizing device 1 and a palletizing device 2. The palletizing device 1 includes a separation conveying section 11, a carton transfer conveying section 12, a transition conveying section 13, a lane conveying section 14, a stacking layer stacking section 15, a stacking layer sorting section 16 and a stacking layer conveying section 17 which are sequentially arranged along the cargo conveying direction. The palletizing device 2 includes a palletizing robot 21 and a palletizing platform 22. The separation conveying section 11 is used to disperse and convey cargo boxes 100 and increase the distance between the cargo boxes 100. The carton transfer conveying section 12 can turn the cargo boxes 100. The lane conveying section 14 is used to vertically transfer the cargo boxes 100. The cargo boxes 100 are transported in lanes perpendicular to the conveying direction. The stacking layer stacking section 15 stacks the cargo boxes 100 to form a loose single-layer cargo stack 200. The stacking layer sorting section 16 sorts the loose single-layer cargo stack 200 into a regular stack 300 that matches the width and length of a truck compartment (not shown in the figure). The stacking layer conveying section 17 conveys the regular stack 300 to the palletizing robot 21. The palletizing robot 21 is used to transfer the regular stack 300 to the palletizing platform 22. Several regular stacks 300 are stacked on the palletizing platform 22 to form a whole stack 400 that matches the height of the truck compartment.

[0027] The stacking system of this embodiment first uses the separation conveying section 11 to send the cargo boxes 100 one by one into the carton transfer conveying section 12. Specifically, the separation conveying section 11 includes a low-speed conveyor belt 111 and a high-speed conveyor belt 112 connected end to end. The cargo boxes 100 have a faster moving speed on the high-speed conveyor belt 112, so that the cargo boxes 100 are separated in the process of transitioning from the low-speed conveyor belt 111 to the high-speed conveyor belt 112, and separation is achieved, which is convenient for the subsequent lane separation operation. The cargo box 100 turns or does not turn in the carton transfer conveying section 12. The length and width of the cargo box 100 are usually not equal. The width of the truck compartment is usually not an integer multiple of the length or width of the cargo box 100, resulting in unusable space in the truck compartment. This turning operation can make the size of the final stack of cargo 400 better match the size of the truck compartment, making full use of the space in the truck compartment. After passing through the transition conveying section 13, the cargo box 100 is conveyed in the lane conveying section 14. The lane conveying mechanism is a prior art and its principle is not introduced in detail here. The lane conveying section 14 arranges the cargo box 100 into a single-layer cargo stack 200 of a certain width in the stacking layer stacking section 15. The stacking layer stacking section 15 only performs preliminary operations on the arrangement of the cargo box 100. The cargo box 100 is further regularized in the subsequent stacking layer sorting section 16 to form a regular stack 300 that matches the width and length of the truck compartment. This step-by-step operation can improve the sorting efficiency of the cargo box 100. The stacking layer conveying section 17 conveys the regular stack 300 to the palletizing robot 21. The palletizing robot 21 stacks the regular stack 300 on the palletizing platform 22 until a complete stack 400 that matches the height of the truck compartment is formed on the palletizing platform 22. The whole process is highly automated with little human intervention, and the final stack of cargo 400 can match the size of the truck compartment, which is convenient for loading operations and greatly improves loading efficiency.

[0028] like Figure 2 As shown, the carton transfer conveying section 12 includes a first conveyor belt 121 and a second conveyor belt 122. The second conveyor belt 122 is located at the side of the first conveyor belt 121. The conveying speeds of the first conveyor belt 121 and the second conveyor belt 122 are different. The turning of the cargo box 100 is achieved by two conveyor belts with different speeds. When the cargo box 100 is on the first conveyor belt 121 and the second conveyor belt 122 at the same time, the friction force generated by the speed difference will drive the cargo box 100 to rotate, so that the conveying posture of the cargo box 100 is changed from horizontal to vertical, or from vertical to horizontal.

[0029] Furthermore, the carton conveying section 12 also includes a limit assembly 123. The limit assembly 123 and the second conveyor belt 122 are both arranged on the same side of the first conveyor belt 121. The limit assembly 123 is located upstream of the second conveyor belt 122. The limit assembly 123 includes a swing arm 1231, a mounting seat 1232 and a driving member 1233. The mounting seat 1232 is fixed on one side of the first conveyor belt 121. The swing arm 1231 is rotatably arranged on the mounting seat 1232. The driving member 1233 is fixed on the mounting seat 1232 and connected to the swing arm 1231. The swing arm 1231 in the limiting assembly 123 can rotate under the action of the driving member 1233, and the driving member 1233 can adopt a cylinder. When the swing arm 1231 is retracted, the cargo box 100 will move to the second conveyor belt 122 to realize the turning of the cargo box 100; when the swing arm 1231 is popped out, the cargo box 100 will not move to the second conveyor belt 122, and the cargo box 100 will keep moving on the first conveyor belt 121 without turning.

[0030] like Figure 2 As shown, the carton conveying section 12 also includes a chain 124, a first sprocket 125, a second sprocket 126, a first rotating shaft 127 and a second rotating shaft 128. The first sprocket 125 is fixed on the first rotating shaft 127, and the first rotating shaft 127 drives the first conveyor belt 121 to operate. The second sprocket 126 is fixed on the second rotating shaft 128, and the second rotating shaft 128 drives the second conveyor belt 122 to operate. The first sprocket 125 and the second sprocket 126 are connected by the chain 124, and the first sprocket 125 and the second sprocket 126 have different numbers of teeth, resulting in a different rotation speed of the first rotating shaft 127 and the second rotating shaft 128, thereby achieving different conveying rates for the first conveyor belt 121 and the second conveyor belt 122.

[0031] like Figure 3 As shown, further, the swing arm 1231 includes a connecting plate 12311 and a baffle 12312, the baffle 12312 includes a first segment and a second segment connected at an obtuse angle, one end of the connecting plate 12311 is vertically connected to the first segment, the other end of the connecting plate 12311 is connected to the driving member 1233, and the non-end portion of the connecting plate 12311 is rotatably arranged above the mounting seat 1232 through a connecting shaft 1234. The baffle 12312 is in a bent state, and this form of baffle 12312 can play a good guiding role. When the swing arm 1231 pops out, the cargo box 100 can slide over the surface of the baffle 12312, and the baffle 12312 will not produce a significant impact on the surface of the cargo box 100, effectively preventing the cargo box 100 from being damaged.

[0032] The length of the stacking layer accumulation section 15 is less than or equal to the length of the stacking layer arrangement section 16. Figure 1As shown, the length of the stacking layer stacking section 15 used in this embodiment is less than the length of the stacking layer sorting section 16. The reason for this design is to reduce the overall length of the stacking device 1, considering the space limitation of the stacking system. If the placement space is sufficient, the length of the stacking layer stacking section 15 can also be equal to the length of the stacking layer sorting section 16. The stacking layer stacking section 15, the stacking layer sorting section 16, and the stacking layer conveying section 17 are connected in sequence in this embodiment, mainly for the cargo box 100 transported by the lane conveying section 14 to store three layers of quantity in these three sections, so that there is enough time for the stacking device 2 to stack and form stacking layers with the lane conveying section 14 without stopping and waiting, which greatly improves the operation efficiency. In other embodiments, when the speed is required to be low, the stacking layer stacking section 15 and the stacking layer conveying section 17 can also be omitted, and the cargo box 100 transported by the lane conveying section 14 to form a regular stacking layer 300 directly in the stacking layer sorting section 16 and then regularized, and then transported to the stacking robot 21 for stacking.

[0033] Specifically, in this embodiment, the regular stack layer 300 is formed by splicing two batches of single-layer cargo stacks 200, that is, every two processed cargo boxes 100 on the stack layer stacking section 15 form a regular stack layer 300, thereby optimizing efficiency and reducing space occupancy.

[0034] like Figure 1 As shown, the palletizing robot 21 includes a mechanical arm 211 and a clamp 212 disposed on the mechanical arm 211, and the clamp 212 is a rolling-curtain type clamp 212. The regular stack 300 can enter the clamp 212 as a whole, and the clamp 212 will support the bottom of the regular stack 300 after it is in place, and then transfer it to the palletizing platform 22 to ensure that the shape of the regular stack 300 remains unchanged.

[0035] Further, the regular stacking layer 300 is in the shape of a rectangular parallelepiped, and the conveying direction of the regular stacking layer 300 on the stacking layer conveying section 17 is parallel to its long side, and the conveying direction of the regular stacking layer 300 on the stacking platform 22 is parallel to its wide side. After being carried by the stacking robot 21, the regular stacking layer 300 changes direction, and changes from the wide side forward to the long side forward conveying posture. That is, the length of the long side of the regular stacking layer 300 matches the width of the truck compartment, and the length of the truck compartment is slightly larger than the integral multiple of the width of the regular stacking layer 300. The reason for this arrangement is to reduce the number of lanes of the cargo box 100 on the lane conveying section 14, and to reduce the processing difficulty of the stacking layer accumulation section 15, and these two stages are exactly the two most time-consuming parts in the stacking process, so the efficiency of stacking can be improved.

[0036] like Figure 4As shown, in another specific embodiment, the stacking system further includes a loading platform 3, one end of which is connected to the stacking platform 22, and the truck compartment can be connected to the other end of the loading platform 3. The loading platform 3 can receive the whole stack of goods 400 input from the stacking platform 22, so that the stacking platform 22 can continuously receive the regular stacking layer 300 transported from the stacking robot 21, ensuring the continuous operation.

[0037] Furthermore, the length of the loading platform 3 is not less than the length of the truck compartment, and the loading platform 3 can be moved into the truck compartment. The loading platform 3 includes a bracket 31 and a slide plate 32, and the slide plate 32 can move on the bracket 31. The length of the loading platform 3 is not less than the length of the truck compartment. When the loading platform 3 is full of stacks of goods 400, the loading platform 3 can deliver all the stacks of goods 400 it carries into the truck compartment at one time, greatly improving the loading efficiency.

[0038] The above embodiments are only used to illustrate the detailed scheme of the present invention, and the present invention is not limited to the above detailed scheme, that is, it does not mean that the present invention must rely on the above detailed scheme to be implemented. Those skilled in the art should understand that any improvement of the present invention, equivalent replacement of various raw materials of the product of the present invention, addition of auxiliary components, selection of specific methods, etc., all fall within the protection scope and disclosure scope of the present invention.
