The two sides of the conveying belt 21 are slidingly arranged in the inner sliding groove 221 and the outer sliding groove 231, and the two sides of the conveying belt 21 are guided and limited by the inner sliding groove 221 and the outer sliding groove 231, so as to ensure the stable operation of the conveying belt 21, and at the same time,

[0037] As shown in the figure, Figure 7 In the embodiment, the outer guide rail 23 is provided with a avoiding part 232, and the outer guide rail 23 corresponding to each layer of the goods taking and placing platform 26 is provided with the avoiding part 232, so as to avoid the interference of the outer guide rail 23 to the taking and placing of the goods.

[0038] In the embodiment, Figure 2 As shown in the figure, the goods placing mechanism 3 comprises a first lifting module 31 and a pushing module 32. The first lifting module 31 is arranged on the support base 11 and located in the inner side region of the inner guide rail 22, and the pushing module 32 is arranged on the lifting module. In the embodiment, the first lifting module 31 can adopt a lead screw nut mechanism, a synchronous belt linear module, etc., as long as it meets the requirement of up-down lifting. In the embodiment, the first lifting module 31 is not limited. The first lifting module 31 can drive the pushing module 32 to move up and down, cooperate with the pushing module 32, push the goods on each layer of the goods taking and placing platform 26 to the corresponding layer plate of the goods shelf 8, and realize the placing of the goods. In the embodiment, the pushing module 32 can adopt an electric push rod, a cylinder, a telescopic arm 431, etc., and the pushing module 32 is not limited in the embodiment.

[0039] In the embodiment, Figure 2 And Figure 6As shown, the goods carrying mechanism 4 includes a second lifting module 41, a goods transfer assembly, and a goods dragging assembly 43. The second lifting module 41 is arranged on the support base 11 and located outside the outer guide rail 23. The goods transfer assembly is connected with the second lifting module 41. The goods dragging assembly 43 is arranged on the goods transfer assembly. The second lifting module 41 drives the goods transfer assembly to move up and down, so that the goods transfer assembly receives the goods 7 pushed by the pushing module 32 during loading, and receives the goods 7 dragged from the deck of the goods shelf 8 by the goods dragging assembly 43 during unloading.

[0040] In the embodiment, the second lifting module 41 can adopt a lead screw nut mechanism, a synchronous belt linear module, etc., as long as it meets the up-and-down lifting requirement. In the embodiment, the goods transfer assembly includes a synchronous belt conveyor 42. The goods dragging assembly 43 includes telescopic arms 431 and clamping devices 432. The telescopic arms 431 are arranged on both sides of the synchronous belt conveyor 42. The front ends of the telescopic arms 431 are provided with the clamping devices 432. During actual unloading, the second lifting module 41 is lifted to the deck of the corresponding goods shelf 8, and then the telescopic arms 431 are extended. The ends of the telescopic arms 431 are located behind the goods 7. At this time, the clamping devices 432 act on the rear side of the goods 7, and then the telescopic arms 431 are retracted to drive the goods 7 to slide along the deck of the goods shelf 8. Finally, the goods 7 slide onto the synchronous belt conveyor 42, are conveyed by the synchronous belt conveyor 42, and enter the corresponding goods loading and unloading platform 26, thereby completing the unloading operation.

[0041] In the embodiment, the goods are loaded and unloaded by pushing and dragging, so that the goods do not need to use a pallet, and the conveying of the goods can be realized. Compared with the current fork loading and unloading, which needs to use a pallet, the cost can be significantly saved, and the operation process is simplified. At the same time, a common deck shelf 8 can be used, and a special deck with an avoidance hole for avoiding the fork is not needed, thereby further reducing the cost.

[0042] In the embodiment, the telescopic arm 431 belongs to the prior art, and the clamping device 432 adopts an electric cylinder. The piston rod of the electric cylinder is provided with a clamping jaw, thereby realizing the clamping and stopping of the goods.

[0043] In actual use, when the synchronous belt conveyor 42 delivers the goods 7 to the shelves 8, the goods 7 can only stay at the edge of the layer plate, which can cause a dangerous situation. In the embodiment, the first auxiliary pushing device 5 is arranged to solve the problem. The first auxiliary pushing device 5 comprises a first electric push rod 51 and a first push head 52. The first push head 52 is arranged on the first electric push rod 51. When not in use, the first push head 52 is below the synchronous belt of the synchronous belt conveyor 42 and does not interfere with normal delivery. When the goods are pushed to a position beyond the first push head 52, the first electric push rod 51 is actuated to push the goods with the first push head 52, thereby assisting the pushing of the goods to the layer plate of the shelves 8.

[0044] When the synchronous belt conveyor 42 delivers the goods 7 to the conveyor belt 21, the goods 7 can only stay at the edge of the conveyor belt 21, which can cause a dangerous situation. In the embodiment, the second auxiliary pushing device 6 is arranged to solve the problem. The second auxiliary pushing device 6 comprises a second electric push rod 61 and a second push head 62. The second push head 62 is arranged on the second electric push rod 61. When not in use, the second push head 62 is below the synchronous belt of the synchronous belt conveyor 42 and does not interfere with normal delivery. When the goods are pushed to a position beyond the second push head 62, the second electric push rod 61 is actuated to push the goods with the second push head 62, thereby assisting the pushing of the goods to the conveyor belt 21.

[0045] To ensure smooth pushing of the goods on the conveyor belt 21, in the embodiment, Figures 7-9 As shown, the conveyor belt 21 is provided with a plurality of conveying wheels 211. The conveying wheels 211 are arranged along the width direction of the conveyor belt 21 and are arranged along the length direction of the conveyor belt 21. The rotation direction of the conveying wheels 211 is perpendicular to the movement direction of the conveyor belt 21, so that the friction between the goods and the conveyor belt 21 is small when the goods are pushed, ensuring that the goods can be quickly pushed out. In the embodiment, the conveying wheels 211 are made of rubber material. The arrangement of the conveying wheels 211 also increases the friction between the goods and the goods transported by the screw.

[0046] At the same time, guide wheels 212 are arranged at the two side edges of the conveyor belt 21. The guide wheels 212 are arranged along the length direction of the conveyor belt 21. The guide wheels 212 are clamped between the inner slide groove 221 and the outer slide groove 231, thereby ensuring smooth operation of the conveyor belt 21.

[0047] Working principle:

[0048] In actual use, the horizontal part of the upper end or the lower end of the spiral guide rail is connected with the logistics equipment, production line and the like, and receives the goods 7. After the goods 7 are received, the goods 7 are arranged in sequence along the spiral conveying belt 21, so that the stacker can store more goods 7 at a time. When stacking, the walking mechanism 1 is moved to the front of the target goods shelf 8. When it is needed to place goods on the shelf 8 plate at the corresponding height, the target goods 7 are driven to the goods taking and placing platform 26 at the corresponding height through the movement of the conveying belt 21. At this time, the first lifting module 31 is raised to the corresponding height, the second lifting module 41 is raised to the corresponding height, the pushing module 32 works, and the goods 7 on the conveying belt 21 are pushed out. After the goods 7 are pushed out, they are pushed to the synchronous belt conveyor 42, and the goods 7 are driven on the shelf 8 plate through the synchronous belt conveyor 42. At this time, the first electric push rod 51 acts, and the goods 7 are continuously pushed into the shelf 8 plate by a small section, so as to avoid the goods 7 from falling, thereby completing the storage of a box of goods. The above actions are repeated to realize the storage of all goods 7. When it is needed to take goods, Figure 5 As shown, the second lifting module 41 is adjusted to the corresponding height. At this time, the telescopic arm 431 works, the telescopic arm 431 extends from the side of the goods, the end of the telescopic arm 431 is located behind the goods, then the clamping device 432 acts and is stopped behind the goods 7, the telescopic arm 431 is retracted, the goods 7 are slid along the plate to the synchronous belt conveyor 42, the goods are conveyed to the goods taking and placing platform 26 at the corresponding height through the synchronous belt conveyor 42, and the second electric push rod 61 acts, the goods are continuously pushed to the inside of the conveying belt 21 by a small distance, thereby completing the taking of the goods 7.

[0049] The mobile stacker has the advantages of simple structure, reasonable design, high working efficiency and being conducive to large-scale promotion.
