It can be seen that the support frame 1 is a convex structure, and the transfer conveying module 22 is set at a high position in the middle of the support frame 1, and cooperates with the low-position loading and conveying module 21 and the unloading and conveying module 23 to load and unload and transfer pallets. When the external manipulator takes away the product on the pallet 5 at the top of the lifting position of the loading and conveying module 21, the lateral transfer component 6 sucks the empty pallet 5 and places it at the lifting position of the unloading and conveying module 23 to wait for subsequent operations. When the unloading and conveying module 23 has the pallet 5 where the product has not been placed, and the loading and conveying module 21 has the empty pallet 5 that needs to be transported, the lateral transfer component 6 will transport the empty pallet 5 above the loading and conveying module 21 to the transfer conveying module 22. When the unloading conveyor module 23 needs an empty pallet 5, and the loading conveyor module 21 does not have an empty pallet 5, the lateral transfer assembly moves the empty pallets 5 on the transfer conveyor module 22 to the unloading conveyor module 23. When there are too many empty pallets 5 on the transfer conveyor module 22, the lifting position drops, and the lateral transfer assembly 6 starts to move several empty pallets 5 to the unloading position, and the lifting position is reset. The multi-line operation logic runs repeatedly in this way.

[0024] like Figures 2 to 5 As shown, in this embodiment, the lifting module 4 includes a Z-axis lifting cylinder 41 and a lifting bracket 42. The connecting end of the lifting bracket 42 is connected to the movable end of the Z-axis lifting cylinder 41. The supporting end of the lifting bracket 42 is provided with a lifting platform 43. The Z-axis lifting cylinder 41 drives the lifting platform 43 to cooperate with a plurality of stacked trays 5. One end of the lifting platform 43 is provided with a plurality of first sensors 7. The plurality of first sensors 7 cooperate with a plurality of trays 5. It can be seen that the Z-axis lifting gas rod 41 drives the lifting platform 43 to rise and lift the plurality of stacked trays 5 to the clamping position of the external manipulator. The plurality of first sensors 7 can sense the presence or absence of trays on the lifting platform 43 to achieve product loading.

[0025] like Figure 1 , Figure 4 as well as Figure 6As shown, in this embodiment, the lifting ends of the loading conveying module 21 and the unloading conveying module 23 are also provided with a pallet positioning module 8, and the pallet positioning module 8 includes a plurality of support columns 81, a positioning plate 82, an X-axis cylinder 83, an X-axis reference block 84, a Y-axis cylinder 85, and a Y-axis reference block 86. A through hole 87 is provided in the middle of the positioning plate 82, and the movable end of the lifting module 4 drives a plurality of the pallets 5 to cooperate with the X-axis cylinder 83, the X-axis reference block 84, the Y-axis cylinder 85, and the Y-axis reference block 86 through the through hole 87. It can be seen that the lifting cylinder 41 drives the lifting platform 43 to make a plurality of the pallets 5 cooperate with the X-axis cylinder 83, the X-axis reference block 84, the Y-axis cylinder 85, and the Y-axis reference block 86, so as to automatically position the pallets 5 of different sizes, and position the pallets 5 at the clamping position and the transfer adsorption position of the external manipulator.

[0026] like Figure 6 As shown, in this embodiment, the positioning plate 82 is further provided with a plurality of material dividing cylinders 9, and a plurality of material dividing sheets 10 are provided at the movable ends of the plurality of material dividing cylinders 9, and the plurality of material dividing sheets 10 cooperate with the plurality of stacked trays 5. It can be seen that the material dividing cylinders 9 drive the material dividing sheets 10 to separate the plurality of stacked trays 5, so as to prevent the plurality of trays 5 from being taken away together during transfer and adsorption, causing the trays 5 at the bottom to fall off.

[0027] like Figure 6 As shown, in this embodiment, the positioning plate 82 is further provided with a plurality of second sensors 11, and the plurality of second sensors 11 are inductively matched with the top tray 5 stacked on the lifting module 4. It can be seen that the plurality of second sensors 11 can sense the positioning of the tray 5 on the positioning plate 82 to ensure the smooth progress of subsequent loading.

[0028] like Figure 4 and Figure 8As shown, in the present embodiment, the loading end and the buffer end of the loading conveying module 21, the unloading end of the transfer conveying module 22, and the buffer end and the lower end of the unloading end of the unloading conveying module 23 are all provided with a pallet blocking module 12, and the pallet blocking module 12 includes a blocking support plate 121, a blocking cylinder 122 and a third sensor 123, the blocking cylinder 122 and the third sensor 123 are arranged on one side of the blocking support plate 121, and a blocking block 124 is arranged at the movable end of the blocking cylinder 122, and several of the blocking blocks 124 pass through the loading end and the buffer end of the loading conveying module 21, the unloading end of the transfer conveying module 22, and the buffer end and the unloading end of the unloading conveying module 23 to limit the several stacked pallets 5, and the third sensor 123 cooperates with the sensing of the several stacked pallets 5. It can be seen that the plurality of blocking cylinders 122 drive the blocking blocks 124 to rise so that the plurality of stacked trays 5 can be loaded, cached, lifted for retrieval, transferred and unloaded in an orderly manner.

[0029] like Figure 1 , Figure 3 as well as Figure 7 As shown, in this embodiment, the lateral transfer assembly 6 includes a transfer bracket 61 and a transfer linear module 62, the transfer linear module 62 is arranged at the upper end of the transfer bracket 61, the movable end of the transfer linear module 62 is provided with an adsorption lifting cylinder 63, the movable end of the adsorption lifting cylinder 63 is provided with an adsorption plate 64, the adsorption plate 64 is provided with a plurality of adsorption nozzles 65, and the plurality of adsorption nozzles 65 are adsorbed and matched with the upper end surface of the tray 5. It can be seen that the transfer linear module 62 and the adsorption lifting module 65 drive the adsorption plate 64 to move and lift so that the plurality of adsorption nozzles 65 adsorb the tray 5 to cooperate with the loading conveying module 21, the transfer conveying module 22 and the unloading conveying module 23 for transfer, so as to realize loading, transfer and unloading.

[0030] like Figure 2 and Fig. 9 As shown, in this embodiment, both sides of the loading conveying module 21, the transfer conveying module 22 and the unloading conveying module 23 are provided with limit plates 13, and the edges of the limit plates 13 are provided with guide bevels 15, and the limit plates 13 cooperate with the stacked plurality of trays 5. It can be seen that the stacked plurality of trays 5 enter the limit plates 13 through the guide bevels 15, and the limit plates 13 keep the stacked plurality of trays 5 flat, preventing the trays 5 from falling due to deviation during the lifting process.

[0031] like Figure 2 and Fig. 9As shown, in this embodiment, an adjustable module 14 is provided on one side of the limit plate 13, and the adjustable module 14 includes a connecting plate 141 and a limit locking mechanism 142. A plurality of support columns 81 are provided on the support frame 1, and the connecting plate 141 is connected to one side of the limit plate 13. The connecting plate 141 is limitedly matched with a plurality of support columns 81 through the limit locking mechanism 142. It can be seen that the limit locking mechanism 142 can adjust the position of the limit plate 13, and is suitable for pallets of various sizes and heights, and has stronger applicability.

[0032] The working principle of the utility model is as follows: when the equipment performs single-line operation and conveying: a number of the pallets 5 are circulated on the loading and conveying module 21, and are transferred to the cache position. The pallet blocking module 12 rises, and the loading position is loaded with pallets. The pallet blocking module 12 descends, and a number of the pallets at the loading position and the cache position are circulated at the same time. The pallets on the cache position are transferred to the lifting position. The lifting module 4 lifts and positions the pallets 5 for subsequent operations.

[0033] When the equipment performs multi-line operation and flow loading: a number of the pallets 5 flow on the loading conveying module 21, and flow to the lifting position. The lifting module 4 lifts the pallets 5. When the pallets 5 reach a certain height, the pallet positioning module 8 positions the top pallet 5 and waits for the external manipulator to take away the products in the pallet 5. After taking out the products, the empty pallet 5 is transported to the unloading conveying module 23 through the lateral transfer assembly 6 to wait for subsequent operations.

[0034] When the equipment performs multi-line operation and unloading: when the unloading conveying module 23 has the pallets 5 that have not been fully loaded with products, and the loading conveying module 21 has empty pallets 5 that need to be moved, the lateral transfer component 6 will move the empty pallets 5 on the loading conveying module 21 to the transfer conveying module 22. When the unloading conveying module 23 needs empty pallets 5, and the loading conveying module 21 does not have empty pallets 5, the lateral transfer component 6 will move the empty pallets 5 on the transfer conveying module 22 to the unloading conveying module 23. When there are too many empty pallets 5 stacked on the transfer conveying module 22 and the lifting position drops, the lateral transfer component 6 starts to move several empty pallets 5 to the unloading position, and the lifting position is reset. The multi-line operation logic is repeated in this way.

[0035] Although the embodiments of the present invention are described with practical solutions, they do not constitute limitations on the meaning of the present invention. For those skilled in the art, it is obvious to modify the implementation scheme and combine it with other solutions based on this description.
