[0036] By setting up the repository 1, the unpacking group 2, the handling group 3, the packaging group 4, and the stacking group 5, the in-line packaging, storage, and transportation system for multi-specification products can execute the in-line packaging, storage, and transportation method for multi-specification products, realizing the full-process operation of uninterrupted parallel production, boxing, packing, and warehousing of multi-specification products.

[0037] Refer to Figure 4 As shown, specifically, the repository 1 is used to store auxiliary supporting supplies such as empty pallets and empty packing boxes, as well as the final products. The first inbound / outbound end 11 of the repository 1 is used for the inbound of auxiliary supporting supplies and the outbound of the final products, and the second inbound / outbound end 12 of the repository 1 is used for the outbound of auxiliary supporting supplies and the inbound of the final products. The stack of empty pallets and the stack of empty packing boxes are inbound from the first inbound / outbound end 11 and are outbound from the second inbound / outbound end 12 when production is needed. Specifically, multiple palletizers / depalletizers 27 are provided, and the multiple palletizers / depalletizers 27 are respectively arranged at the end of the first unpacking conveyor line 24 and the in-line position corresponding to the palletizing area 45. The stack of empty pallets is transported to the corresponding palletizer / depalletizer 27 for depalletizing one by one; the stack of empty packages is transported to the unpacking group 2 and then transported by the handling group 3 and thus distributed to the production line 6 for filling.

[0038] Refer to Figure 5 As shown, the first unpacking machine 21 unpacks and assembles large cartons. The palletizer / depalletizer 27 depalletizes the stack of empty pallets. After the large cartons are assembled, the first unpacking conveyor line 24 transports the large cartons to the position of the palletizer / depalletizer 27, and the liftable fork on one side of the palletizer / depalletizer 27 is used to complete the combination of the large cartons and the empty pallets to form a stack of large cartons 7.

[0040] The third unpacking machine 23 unpacks and assembles small cartons. After the small cartons are assembled, the third unpacking conveyor line 26 transports the small cartons to the CTU vertical warehouse 32 docked at the end. Subsequently, the CTU vehicle 33 transports multiple small cartons to the production line 6 for filling at one time. By setting up the CTU vertical warehouse 32 and the CTU vehicle 33, multiple small cartons can be transported at one time, optimizing the handling plan for small cartons with small volume, light weight, and fast filling, thus improving the packaging, storage, and transportation efficiency of small cartons.

[0041] The packing boxes completed with filling on production line 6 are carried by handling group 3 to packing conveyor line 41. Preferably, packing conveyor line 41 can be provided with an infeed point. The large packing boxes, medium packing boxes and small packing boxes completed with filling all enter the line through this infeed point. After entering the line, they are identified by identifier 42; packing conveyor line 41 can also be correspondingly provided with three infeed points, namely large packing box infeed point 411, medium packing box infeed point 412 and small packing box infeed point 413. The large packing boxes, medium packing boxes and small packing boxes completed with filling enter the line from the corresponding infeed points respectively. After entering the line, they are identified by identifier 42. Labeller 43 labels the packing boxes after entering the line, and capping and strapping machine 44 caps and straps the labelled packing boxes.

[0042] Packing conveyor line 41 continues to convey the packing boxes. Since the large packing boxes have been combined with pallets into large packing box stacks 7, the large packing box stacks 7 are directly conveyed to stretch wrapping and packing machine 46 for stretch wrapping and packing; both medium packing boxes and small packing boxes need to be palletized. Therefore, packing conveyor line 41 conveys the medium packing boxes and small packing boxes to stacking area 45.

[0043] Refer to Figure 5 and Figure 6 As shown, preferably, stacking area 45 includes a first palletizing area 451 for palletizing medium packing boxes. In first palletizing area 451, there are palletizing robots 452, turntable conveyor line 453 and multiple buffer conveyor lines 454.

[0044] Specifically, packing conveyor line 41 conveys medium packing boxes into first palletizing area 451. Before flowing in, obtain the product specification category of the products filled in the medium packing box, and judge whether there are medium packing boxes with the same product specification category as the products filled in the medium packing box on multiple buffer conveyor lines 454. Each buffer conveyor line 454 is used to place medium packing boxes filled with a certain product specification; if not, buffer conveyor line 454 transports an empty pallet to turntable conveyor line 453, and palletizing robot 452 stacks the medium packing box on the empty pallet and transports the medium packing box and the empty pallet to one of the buffer conveyor lines 454; if already existing, buffer conveyor line 454 transports the existing medium packing boxes with the same product specification category as the products filled in the medium packing box and the empty pallet to the stacking position, and palletizing robot 452 stacks the medium packing box vertically on the existing medium packing boxes to palletize into medium packing box stack 8. Subsequently, packing conveyor line 41 conveys medium packing box stack 8 to stretch wrapping and packing machine 46 for stretch wrapping and packing.

[0045] Refer to Figure 5As shown, preferably, the palletizing area 45 further includes a second palletizing area 455 for palletizing small cartons.

The picking platform 456 is connected to the packaging conveyor line 41. The picking robot 457 is used to pick and palletize small cartons, and the palletizing conveyor line 458 is used to convey the palletized small carton stacks 9.

[0046] Specifically, the packaging conveyor line 41 conveys small cartons into the second palletizing area 455. Before flowing in, the product specification category filled in the small carton is obtained. The picking robot 457 picks multiple small cartons filled with the same specification products on the picking platform 456 and lays them flat to palletize into a single layer of small cartons with a preset quantity. It is judged whether there is a single layer of small cartons on the palletizing conveyor line 458 with the same product specification category as that filled in this single layer of small cartons. If not, the palletizing conveyor line 458 transports an empty pallet, and the picking robot 457 stacks this single layer of small cartons onto the empty pallet; if so, the picking robot 457 vertically stacks this single layer of small cartons onto the existing single layer of small cartons to palletize into a small carton stack 9, and then transports the palletized small carton stack 9 onto the packaging conveyor line 41. The packaging conveyor line 41 transports the small carton stack 9 to the stretch wrapping and packing machine 46 for stretch wrapping and packing.

[0047] By first laying flat and palletizing small cartons with small volume, light weight, fast filling, and large quantity into a single layer of small cartons with a preset quantity, the adaptability of the packaging storage and transportation system to small cartons is enhanced, and the palletizing efficiency of small cartons is improved.

[0048] Preferably, multiple picking channels are provided on the picking platform 456 to adapt to a relatively large number of small cartons for reasonable distribution and ensure the quick selection and palletizing of the picking robot 457.

[0049] Preferably, a manual palletizing area 4551 is also provided in the second palletizing area 455. When production is busy and the quantity of small cartons to be packaged is large, manual labor is used to assist in palletizing the small carton stacks 9 to improve the packaging efficiency.

[0050] Preferably, a transfer vehicle 459 is also provided in the second palletizing area 455. The transfer vehicle 459 is used to transfer the small carton stack 9 onto the packaging conveyor line 41.

[0051] The large carton stacks 7, medium carton stacks 8, and small carton stacks 9 after stretch wrapping and packing all exit from the end of the packaging conveyor line 41. The stacking robot 52 stacks multiple large carton stacks 7, multiple medium carton stacks 8, and multiple small carton stacks 9 filled with the same specification products respectively and transports them to the storage warehouse 1 for storage.

[0052] Refer to Figure 7As shown, preferably, a large cardboard box stack area 13, a medium cardboard box stack area 14, and a small cardboard box stack area 15 are arranged in the repository 1. Multiple product specification partitions are arranged in the large cardboard box stack area 13, the medium cardboard box stack area 14, and the small cardboard box stack area 15, so as to further improve the efficiency of inbound and outbound management of multi-specification products.

[0053] Preferably, the in-line packaging storage and transportation system for multi-specification products further includes a warehousing control system. The warehousing control system is used to implement tracking of material information and control information for each circulation link of the materials.
