[0001] The present invention relates to the technical field of cargo sorting, and in particular to a follow-up automatic package supply platform and a cargo sorting system. Background Art

[0002] With the rapid development of e-commerce and increasingly fierce competition in the market, automated equipment is becoming increasingly important in the e-commerce sector. Sorting is a key step in e-commerce order picking. To improve sorting efficiency and simplify order collection operations, intelligent sorting equipment that can automatically sort goods is gradually being used.

[0003] In existing intelligent sorting equipment, to ensure the accuracy of cargo delivery, sorting vehicles have two methods for obtaining cargo from the supply platform. The first method requires that when the sorting vehicle reaches the supply platform, it must stop and wait for the supply platform to complete the delivery before continuing to move. The second method relies on manual running back and forth to deliver cargo to the sorting vehicle when the sorting vehicle is about to reach the supply location. Obviously, in the first case, the sorting vehicle needs to stop moving to complete the delivery, which is less efficient. In the second case, not only does it consume a lot of human resources, but it also poses certain safety risks. The fast-moving sorting vehicle can easily cause injuries to workers.

After the fixed buffer location 111 obtains the goods, it can temporarily store the goods on the intermediate platform and then pass the goods to the next adjacent fixed buffer location 111 (that is, adjacent fixed buffer locations 111 can transfer goods in one direction). The last fixed buffer location 111 is connected to the mobile vehicle 112, and the goods can be passed to the mobile vehicle 112.

[0040] In one embodiment of the present invention, a control cabinet is provided below the fixed cache location 111 , and a programmable logic controller and a drive control module are provided inside the control cabinet.

[0041] Figures 5, 6, and 7 illustrate schematic structural diagrams of a mobile vehicle 112 according to one embodiment of the present invention.

[0044] In one embodiment of the present invention, a reflector (not shown) is provided on the sorting cart 121, and a position detection sensor 1129 is installed on the side of the mobile cart facing the rotating seeding mechanism 120. The position detection sensor 1129 can determine whether the mobile cart 112 and the sorting cart 121 have achieved synchronous movement. When the mobile cart 112 moves along with the sorting cart 121, the position detection sensor 1129 can continuously emit a signal. When the signal contacts the reflector on the sorting cart 121, it can be reflected back by the reflector to form a reflected signal. When the position detection sensor 1129 receives the reflected signal, it can be determined that the mobile cart 112 and the sorting cart 121 have achieved synchronous movement. At this time, the control unit can control the driving mechanism on the mobile cart 112 to drive the cargo conveyor belt 1122 to deliver the cargo to the sorting cart 121.

[0045] Figure 8 shows a schematic structural diagram of a follower module assembly 113 according to one embodiment of the present invention. As shown in Figure 8 , the follower module assembly 113 includes a bracket 1131 , a slider guide 1132 , a base plate 1133 , a mechanical limit assembly 1134 , a synchronous belt 1135 , a tensioning pulley 1136 , and a driving assembly 1137 .

[0046] In one embodiment of the present invention, the follower module assembly 113 includes a slider rail 1132 and a timing belt mechanism. The slider rail 1132 is connected to the mobile vehicle 112, allowing the mobile vehicle 112 to slide on the slider rail 1132. The timing belt mechanism is connected to the mobile vehicle 112 and can drive the mobile vehicle 112 to perform linear reciprocating motion along the slider rail, so that the mobile vehicle 112 can move synchronously with the sorting vehicle 121.

[0047] In one embodiment of the present invention, the follower module assembly 113 includes a bracket 1131, a base plate 1133, and a synchronous belt mechanism. A slider rail 1132 is mounted on the bracket 1131; the trolley 112 is mounted on the base plate 1133, and the base plate 1133 is slidably connected to the slider rail 1132. The synchronous belt mechanism is mounted on the bracket 1131, and the base plate 1133 is fixed to the synchronous belt mechanism. The synchronous belt mechanism can drive the base plate 1133 and the trolley 112 mounted on the base plate 1133 to move along the slider rail 1132.

[0048] In one embodiment of the present invention, the follower module assembly 113 further includes a mechanical limit assembly 1134. The mechanical limit assembly 1134 is mounted at both ends of the slider guide rail 1132 and is capable of limiting the extreme positions of the movement of the mobile vehicle 112. In a specific embodiment, the mechanical limit assembly 1134 is mounted at both ends of the bracket 1131 and limits the extreme positions of the movement of the mobile vehicle by limiting the extreme positions of the movement of the base plate 1133. Specifically, the mechanical limit assembly 1134 is used to limit the extreme positions of the mobile vehicle 112 when the mobile vehicle 112 moves along the slider guide rail 1132, wherein when the mobile vehicle 112 moves to the extreme position in the first direction along the slider guide rail 1132, the mechanical limit assembly 1134 can limit the mobile vehicle 112 from continuing to move in the first direction along the slider guide rail 1132. At this time, it is necessary to switch the movement direction of the mobile vehicle 112 so that the mobile vehicle 112 moves in a second direction opposite to the first direction along the slider guide rail 1132, so that the mobile vehicle 112 returns to the initial position and continues to obtain goods from the fixed cache position 111.

[0049] In one embodiment of the present invention, the follower module assembly 113 further includes at least one position detection sensor installed on the follower module assembly, which can detect the position of the mobile vehicle 112, especially the initial position and the extreme position of the movement of the mobile vehicle 112.

The drive assembly 1137 is fixed to the bracket and connected to the synchronous belt 1135. The drive assembly 1137 includes a third drive wheel and a motor. The motor can drive the third drive wheel to rotate, so that the third drive wheel drives the synchronous belt 1135 to move, thereby driving the base plate 1133 and the mobile vehicle 112 on the base plate 1133 to perform linear reciprocating motion along the slider guide rail 1132. The tensioning pulley 1136 is fixed to the bracket 1131, contacts one side of the synchronous belt 1135, and can adjust the tension of the synchronous belt 1135.

[0051] In summary, according to the technical solution of the present invention, a follow-up automatic package supply platform and a cargo sorting system are disclosed. The follow-up automatic package supply platform is used in conjunction with a sorting vehicle in the cargo sorting system. The follow-up automatic package supply platform is provided with a mobile vehicle, a fixed cache position and a follow-up module assembly. After the mobile vehicle obtains the cargo from the fixed cache position, it is driven by the synchronous belt mechanism in the follow-up control module. The mobile vehicle can follow the passing sorting vehicle along the slider guide rail. The mobile vehicle is provided with an in-place detection sensor, and the sorting vehicle is provided with a reflector, which can reflect the signal from the in-place detection sensor. When the in-place detection sensor detects the reflected signal, the mobile vehicle and the sorting vehicle achieve synchronous movement. At this time, the mobile vehicle delivers the cargo to the sorting vehicle. Before the sorting vehicle reaches the follow-up automatic package supply platform, it automatically adjusts to a suitable height to facilitate accurate acquisition of cargo from the package supply platform. In this way, according to the technical solution of the present invention, the mobile vehicle on the package supply platform has the ability to follow and can move synchronously with the passing sorting vehicle. During the package supply process, the sorting vehicle does not need to stop to complete the package supply, replacing manual package supply while avoiding close contact between workers and the sorting vehicle, thereby greatly improving the sorting efficiency and the safety of the workers.
