[0002] Driven by both technology and economy, the logistics industry is rapidly transforming from traditional logistics to modern logistics. During the process of moving goods from the place of origin to the place of consumption, the logistics chain involving multiple links such as transportation, storage, and distribution is evolving towards automation, informatization, intelligence, and unmanned operation. Among the logistics chain, the warehouse for storing goods is an important link.

[0003] In the patent application for invention with the publication number of "CN111846728B", a method and device for warehousing and discharging in a three-dimensional warehouse and a three-dimensional warehouse are disclosed. Among them, the three-dimensional warehouse includes a stacker and a storage unit. The storage unit includes four rows of shelves arranged along a first direction, and each row of shelves extends along a second direction. The middle two rows of shelves are spaced apart to form a lane. The stacker is located in the lane of the storage unit where the warehousing and discharging tasks are to be executed. The two rows of shelves close to the lane have multiple first storage locations, and the two rows of shelves far from the lane have multiple second storage locations. The method for allocating storage locations includes: determining the earliest storage time of all storage locations in the storage unit that meet the conditions for discharging; determining all storage locations that meet the conditions for discharging within the range from the earliest storage time to the earliest storage time plus a preset time period as the set of storage locations that meet the earliest storage time period; preferentially executing the discharging tasks for each storage location in the set of storage locations according to the preset discharging priority order. Although the three-dimensional warehouse discharging system is a relatively mature technology and is widely applied, it is generally installed in a factory building, and a door is provided at the exit of the three-dimensional warehouse discharging system. It cannot directly place the goods on the truck outside the factory building door. Instead, it can only use a forklift to first pick up the goods at the factory building door and place them outside the factory building door. After the truck arrives, the forklift is used to place the goods placed outside the factory building door on the truck. This requires a large amount of space, and the storage of goods and the subsequent placement of the forklift interfere with each other, which is not conducive to the movement of the forklift and has low efficiency.

[0004] In the patent application of invention with the publication number "CN115783816A", it discloses an automatic loading machine and a loading method, belonging to the field of logistics transportation.

In the present utility model, the truss moving platform can drive the belt conveyor system, the 3UPU-UP parallel mechanism, the conveying channel, the lidar, etc. to translate on the truss; by translating on the truss to adjust the relative position between the loading mechanism and the vehicle, so as to complete the loading of the whole vehicle. However, it can only move the goods from one end of the truss to the other end through the truss moving platform. It still needs to use a forklift to pick up the goods at the factory door first and place them outside the factory door. After the truck arrives, then use the forklift to place the goods placed outside the factory door on the truck. It still needs to occupy a large space, which is not conducive to the safe storage and placement of goods.

[0066] Working principle: First, reverse the truck 4000 between the moving frame tracks. After the truck 4000 is stopped steadily, the fifth drive motor 3320 drives the fourth gear 3321 to rotate. Through cooperation with the third rack, it drives the first support block 3300 to move. The first support roller 3330 supports on the upper end of the first partition frame, playing the roles of support and movement. At the same time, the first roller 3341 moves in the first limit groove, playing the roles of support and movement, and can limit the movement of the first support block 3300 to ensure the stable movement of the first support block 3300. Among them, the first bracket 3310 is hinged to the first vertical frame 3120. When there are sundries such as gravel in the moving frame tracks, it will not cause the first vertical frame 3120 to tilt, that is, it can ensure the smooth movement of the first cross frame 3110. Therefore, driven by the fifth drive motor 3320, the truss moving frame 3100 is driven to move along the moving frame tracks. The first laser scanner in the first scanning mechanism and the second laser scanner in the second scanning mechanism follow the truss moving frame 3100, and can scan the angle, position and height of the truck 4000, so as to calculate the quantity of the goods 4100 placed and the specific positions where each good 4100 is placed.

[0067] Then, the automated storage and retrieval system in the factory area can send out the goods 4100 one by one. The first X-axis moving mechanism, the first Y-axis moving mechanism, the first Z-axis moving mechanism and the first R-axis moving mechanism drive the first fork 1610 to move under the pallet of the goods 4100. Among them, before inserting under the goods 4100, the first distance measuring sensor 1612 can detect the position and angle of the goods 4100 to ensure that the first fork 1610 can fork out the goods 4100 and ensure that the position and angle of each goods 4100 on the first fork 1610 are the same (due to the original design of the automated storage and retrieval system for manual unloading by forklift, during the transmission process, small vibrations will occur, resulting in certain deviations in the position and angle of each goods 4100, and accurate positioning cannot be guaranteed). Then, through the first X-axis moving mechanism, the first Y-axis moving mechanism, the first Z-axis moving mechanism and the first R-axis moving mechanism driving the first fork 1610, the goods 4100 are moved to the upper end of the loading platform 2110. Then, in cooperation with the first emission sensor 2112 and the first receiving sensor 2111, it can ensure that the goods 4100 are accurately placed on the upper end of the loading platform 2110 and ensure that each placement of the goods 4100 is neat.

[0068] Finally, according to the positions where each cargo 4100 should be placed, the first reduction gear 2140 drives the first drive rod 2120 to rotate, then the second support roller 2121 moves along the trolley track 2300, and the third support roller 2131 also moves along the trolley track 2300, cooperating with the second support roller 2121 to support the transfer trolley. At the same time, the first positioning disk 2150 also rotates following the second support roller 2121. The first positioning disk 2150 matches the first bolt 2320, and during the movement of the transfer trolley, it can play a role in positioning and limiting, avoiding the problem of the transfer trolley sliding, and ensuring that the displacement distance of the transfer trolley can be controlled more precisely. Then, the second Y-axis moving mechanism, the second Z-axis moving mechanism, and the second R-axis moving mechanism drive the second fork 3710 to move to the position of the transfer trolley. The second fork 3710 forks up the cargo 4100 from the load platform 2110, and then the second Y-axis moving mechanism, the second Z-axis moving mechanism, and the second R-axis moving mechanism drive the second fork 3710 to place the cargo 4100 at the corresponding position; then repeat the operation until all the cargo 4100 is completely placed.

[0069] Among them, the seventh drive motor 3410 drives the sixth gear to rotate. Through cooperation with the fifth rack 3112, it drives the third support frame 3400 to move left and right; the first hydraulic cylinder 3420 pushes the fourth support frame 3500, enabling the fourth support frame 3500 to lift and, through the traction of the first traction belt 3520, enabling the intelligent forklift frame 3600 to move together. Since the first directional wheel 3530 is arranged at the upper end of the fourth support frame 3500 and moves with the fourth support frame 3500, the moving distance of the fifth support frame 3700 is twice the pushing distance of the first hydraulic cylinder 3420. That is, by reducing the travel distance of the first hydraulic cylinder 3420, the size of the truss intelligent forklift can be effectively reduced. Then, the eighth drive motor 3690 drives the seventh gear to rotate. Through the cooperation of the seventh gear and the second internal gear 3720, it drives the fifth support frame 3700 to rotate, that is, drives the second fork 3710 to rotate. In addition, the second support plate 3610 and the intelligent forklift frame 3600 are fixedly connected through the weighing sensor 3620. When the second fork 3710 inserts the goods 4100, the weight of the goods 4100 can be weighed, and it is judged whether it meets the standard. Only the qualified goods 4100 can be placed on the truck 4000. When an error occurs in the goods 4100 and the weight exceeds the standard and reaches the warning value of the tension sensor 3630, an alarm is given. And when placing the goods 4100, if the second fork 3710 collides with the truck 4000 or other objects, the second support plate 3610 supports the second fork 3710 to move along the sixth slide rail 3641, playing a buffering role to avoid direct hard contact resulting in hard damage, such as the occurrence of situations where the goods 4100 are dumped. At this time, the second mounting plate 3680 and the first return roller 3671 have a relative position change. The first return roller 3671 leaves the central low position of the first V-shaped opening 3681, then the first return plate 3670 moves upward, and the first spring rod 3662 is squeezed; when the second fork 3710 leaves the collision position, the elastic force of the first spring rod 3662 pushes the first return plate 3670 downward, pushing the first return roller 3671 to the central low position of the first V-shaped opening 3681, ensuring that the second support plate 3610 moves back to its original position, that is, automatic reset is completed.

[0070] Moreover, when the truck 4000 enters below the automatic loader, its license plate is photographed and recorded. And when the goods 4100 are taken out of the three-dimensional warehouse outbound system, the barcode information of each goods 4100 is recorded. That is, the goods 4100 loaded on each truck 4000 can be recorded, and each goods 4100 can be traced back to the truck 4000.
