Two hinge shafts 174 are symmetrically hinged on both sides of the other end of the push shaft 173. The end face of the hinge shaft 174 is hinged to one end of the insertion shaft 172. The insertion shaft 172 is symmetrically slidably arranged on both sides of the platform 3. The end face of the insertion shaft 172 is slidably engaged with the inner wall of the shell 411, so as to stack the stacked items. When the mechanism is installed, the shell 411 is aligned with the platform 3 and slides in the direction of the platform 3, so that the platform 3 slides into the shell 411 until the platform 3 is completely immersed in the shell 411. During this process, the inner wall of the shell 411 squeezes the push block 171, driving the push shaft 173 to slide into the platform 3. Since the push shaft 173 and the plug shaft 172 are arranged vertically and the length of the hinge shaft 174 remains unchanged, the two plug shafts 172 move synchronously in opposite directions, and the end faces of the plug shaft 172 extend out from both sides of the platform 3 and engage with the inner wall of the shell 411 to achieve limiting.

When the inclined shaft When the bevel shaft 181 moves outward, the slider 185 slides on the central groove 183, and the bevel direction of the bevel shaft 181 remains unchanged. When the bevel shaft 181 is engaged with the shell 411, the slider 185 slides with the bevel groove 182. The sliding process drives the bevel shaft 181 to rotate 180 degrees, thereby realizing the flipping of the bevel. At this time, when the shell 411 is pulled outward, it cannot slide out. On the contrary, when separating, the slider 185 first passes through the bevel groove 182 to drive the bevel shaft 181 to rotate 180 degrees in the opposite direction, and drives the bevel shaft 181 toward the sorting slide 2, thereby facilitating the separation of the bevel shaft 181 from the shell 411.

[0033] like Figure 1-Figure 12 As shown, the inner wall of the feed rack 417 is provided with a limit groove 191 which is engaged with the inclined plane shaft 181, and the inner wall of the feed rack 417 is provided with an end groove 192 which is adapted to the push block 171, and a magnet 193 is provided in the end groove 192. The end face of the push block 171 is provided with a strong magnetic block which is mutually attracted to the magnet 193, and the magnet 193 is electrically connected to an external power supply. By energizing the magnet 193, the strong magnetic block and the push block 171 move into the end groove 192, driving the hinge shaft 174 to pull the two plug shafts 172 to move toward each other synchronously, and driving the inclined plane shaft 181 to shrink into the inclined groove 182.

[0034] Working principle: Step S1, the sorted express is transferred from the sorting conveyor belt body 1 to the sorting slide 2, and the first spherical wheel conveyor body 415 is driven to make the goods stay briefly on the first spherical wheel conveyor body 415, and the appearance of the goods is quickly scanned by the laser profile scanner 416, and irregular goods are removed, and regular goods are left and conveyed to the second spherical wheel conveyor body 418; Step S2, lift the bracket 6 to the platform 3 through the lifting mechanism, and drive the two guide conveyor belts 9 to rotate, so as to drive the stacking frame 412 at the bottom to move downward, and the bottom plate 811 at the lower end of the stacking frame 412 is separated from the guide conveyor belt 9 and falls steadily on the bracket 6, and the bracket 6 and the guide conveyor belt 9 are adjusted so that the top of the bottom plate 811 is flush with the platform 3; Step S3, the goods that slide onto the second spherical wheel conveyor body 418 can be uniformly conveyed to the bottom plate 811 in a stacking space by the second spherical wheel conveyor body 418, and the second spherical wheel conveyor body 418 places the goods in sequence; Step S4, after one layer of goods is placed, the lifting mechanism is driven to drive the bracket 6 to move downward, and the conveyor belt 9 is guided to rotate, and a partition 812 at the bottom is loosened. Under the action of gravity, the hinge automatically unfolds, so that the partition 812 is just located at the position of the platform 3, and the space between the two partitions 812 opened by the hinge is used to place a new round of goods; Step S5: When the goods that have been placed and moved down pass through the vibration mechanism, the vibration mechanism is driven to push the goods toward the center so that the goods are placed neatly; Step S6, when the second hinge bar 102 passes the photoelectric sensor 116, the motor 115 on the sliding block 111 drives the main gear 113 to rotate, thereby driving the second hinge bar 102 to move in the right-angle groove 112, and moving the second hinge bar 102 to a side close to the platform 3; Step S7, after stacking of one stacking rack 412 is completed, the stacking rack 412 in another stacking space is used for stacking again, and at this time, the stacking rack 412 that has completed stacking can be pushed out from the discharge port 7 by the pushing mechanism.

[0035] After the sorted express is transferred from the sorting conveyor belt body 1 to the sorting slide 2, the goods will first pass through the first spherical wheel conveyor body 415. The first spherical wheel conveyor body 415 is driven to make the goods stay briefly on the first spherical wheel conveyor body 415. During the stay, the laser profile scanner 416 quickly scans the appearance of the goods. If the goods are in a normal square shape, they can be automatically stacked and directly conveyed downward along the sorting slide 2 to the second spherical wheel conveyor body 418 through the first spherical wheel conveyor body 415. If the goods are in an irregular shape, or a spherical shape, or a long strip shape that is difficult to stack, the goods will be directly pushed to one side through the first spherical wheel conveyor body 415 and stacked in advance on the sorting slide. 2 A storage frame is placed below one side, and irregular goods fall directly into the storage frame. This process can sort out goods that are easy to stack, avoiding the collapse of goods after stacking, which causes stacking failure. Before stacking the goods, the bracket 6 is first lifted to the platform 3 by the lifting mechanism, and the two guide conveyor belts 9 are driven to rotate, driving the stacking frame 412 located at the bottom to move downward, and the bottom plate 811 at the lower end of the stacking frame 412 is separated from the guide conveyor belt 9 and falls steadily on the bracket 6. By adjusting the coordination of the bracket 6 and the guide conveyor belt 9, the top of the bottom plate 811 is flush with the platform 3. When the goods slide onto the second spherical wheel conveyor body 418, the second spherical wheel conveyor body 418 can uniformly transport the goods to the bottom plate 81 in a stacking space. 1, among which the spherical wheel conveyor is often used in logistics sorting. It uses the multi-directional rotation characteristics of the spherical roller unit to realize the multi-directional transportation, diversion, guidance and positioning of items. Each spherical roller unit is composed of a high-hardness sphere, a support seat and an internal ball or bearing to ensure that the sphere can rotate freely 360° with low friction. Its power comes from the drive device below, such as a conveyor belt, an active friction wheel or a pneumatic system. The friction generated by contact with the sphere drives the sphere to rotate and move the items in the set direction. The core advantage of the conveyor lies in its flexibility and efficiency. Multiple spherical roller units can be combined into a modular structure. By independently controlling the movement direction and speed of different units, the items can be flexibly switched between functions such as linear transportation, left and right diversion, and rotation guidance. The second spherical wheel conveyor body 418 can be used to push the goods to different positions on the bottom plate 811 in sequence, so that the goods are placed relatively neatly. After one layer is placed, the lifting mechanism is driven to drive the bracket 6 to move down, and at the same time, the conveyor belt 9 is guided to rotate, and the partition 812 at the lower end is loosened. Under the action of gravity, the hinge automatically unfolds, so that the partition 812 is just located at the position of the platform 3. The space between the two partitions 812 opened by the hinge is used to place a new round of goods. Similarly, the goods are placed through the second spherical wheel conveyor body 418. Since the goods placed through the second spherical wheel conveyor body 418 are not particularly neat, when the placed goods move down to the position of the vibration mechanism, the vibration mechanism is driven.The goods can be pushed toward the center to achieve the effect of neat edges. After the goods are neatly placed by vibration, the second hinge bar 102 is moved to the side facing the platform 3, so that the four sides between the adjacent partitions 812 are provided with hinges to achieve the effect of limiting the position of the goods and prevent the goods from falling off during transportation. Repeat the above steps until the entire stacking rack 412 is fully stacked with goods. When one stacking rack 412 is stacked, another stacking rack 412 in the stacking space is used for stacking again. At this time, the stacking rack 412 that has been stacked can be pushed out from the discharge port 7 through the pushing mechanism. The pushed out stacking rack 412 can be manually carried by the staff or transferred by equipment, and the goods are difficult to fall during the transfer process.
