[0036] The present invention is further described in detail below based on the accompanying drawings and implementation examples.

[0037] The directional terms such as up, down, left, right, front, back, front, back, top, bottom, etc. mentioned or may be mentioned in this specification are defined relative to the structures shown in the drawings. The words "inside" and "outside" refer to the direction toward or away from the geometric center of a specific component, respectively. They are relative concepts, and therefore may change accordingly according to different locations and different usage conditions. Therefore, these or other directional terms should not be interpreted as restrictive terms.

[0038] Reference Figure 1 , Figure 2 A multi-layer sorting assembly comprises: a continuous elevator 1, a sorting machine 2, a multi-layer entrance conveying path 3, and a multi-layer exit conveying path 4. Multiple layers of the entrance conveying path 3 are arranged in a vertical range, and multiple layers of the exit conveying path 4 are arranged in another vertical range. The continuous elevator 1 is respectively connected with the multi-layer entrance conveying path 3 and the multi-layer exit conveying path 4 for goods, and the multi-layer exit conveying path 4 is simultaneously connected with the goods of the sorting machine 2, that is, the working mode of the continuous elevator 1 is multi-input and multi-output. The general conveying process of the multi-layer sorting assembly is as follows: the multi-layer entrance conveying path 3 delivers the goods of each layer into the continuous elevator 1, the continuous elevator 1 diverts the goods to the corresponding exit conveying path 4, and then the sorting machine 2 sorts them by layers.

[0039] Regarding the specific arrangement of the continuous elevator 1, the inlet conveyor 3, and the outlet conveyor 4, in the first implementation case, as shown in FIG. Figure 3 As shown, both sides of the continuous elevator 1 are provided with an inlet conveying path 3 and a multi-layer outlet conveying path 4. In the second embodiment, as shown in FIG. Figure 4 As shown, the continuous elevator 1 is provided with an inlet conveying path 3 on both sides and an outlet conveying path 4 on one side. In the third embodiment, as shown in FIG. Figure 5 As shown, the continuous elevator 1 is provided with an inlet conveying path 3 on one side and outlet conveying paths 4 on both sides. The specific arrangement depends on the specific application.

[0040] Reference Figure 6 , Figure 7The continuous elevator 1 includes an elevator frame 10 and a first flexible member 11, a second flexible member 12, and a plurality of elevator trolleys 13 installed in the elevator frame 10. The first flexible member 11 and the second flexible member 12 are both connected by four sprockets 110 and 120, and are the same annular components. The two are the same in shape and running direction. Specifically, the two are roughly rectangular in shape. The first flexible member 11 and the second flexible member 12 are parallel and spaced, and are not side by side. In addition, the first flexible member 11 has two vertical parts, one is an ascending part, and the other is a descending part. Figure 2 Taking the viewing angle as a reference, the first flexible member 11 runs in a clockwise direction, the vertical part on the left side is the ascending part, and the vertical part on the right side is the descending part. Similarly, the vertical part on the left side of the second flexible member 12 is the ascending part, and the vertical part on the right side is the descending part. The hoist trolley 13 is arranged in a continuous arrangement, and its overall horizontal state is maintained, and it is movably connected with the first flexible member 11 and the second flexible member 12 at the same time. Therefore, the total movement path of the hoist trolley 13 matches the shape of the first flexible member 11 and the second flexible member 12, and is a rectangular circulation total path. Corresponding to the running direction of the first flexible member 11 and the second flexible member 12, the total movement path of the hoist trolley 13 is formed by connecting the left vertical ascending path, the upper horizontal rightward movement path, the right vertical descending path, and the lower horizontal leftward movement path.

[0041] Reference Figure 6 , Figure 7 Combined with Figure 8 , Fig. 9 The entrance conveyor path 3 of the multi-layer structure corresponds to the vertical ascending path on the left side of the elevator trolley 13, and the exit conveyor path 4 of the multi-layer structure corresponds to the vertical descending path on the right side of the elevator trolley 13. Since the elevator trolley 13 continuously moves along its total moving path, it docks with the goods on the entrance conveyor path 3 during the ascending process. During this process, when the entrance conveyor path 3 starts to transport the goods, its horizontal height is higher than the horizontal height of the elevator trolley 13. A sensor (not shown in the figure) is set on the entrance conveyor path 3 to measure the length of the goods (the length of the goods along the conveying direction), and the exit conveyor path 4 is adjusted according to the length of the goods. The height difference when docking is designed according to the length of the goods. The basic principle is that the shorter the goods, the smaller the height difference, and the longer the goods, the larger the height difference. This can reduce the impact of falling goods to protect the goods, especially for fragile goods. Similarly, the elevator trolley 13 docks with the goods on the outlet conveying path 4 during the descent process. During this process, the horizontal height of the elevator trolley 13 when transporting the goods must be higher than the horizontal height of the outlet conveying path 4. A sensor (not shown in the figure) is set on the elevator trolley 13 to measure the length of the goods, and the height difference when docking is designed according to the length of the goods.

[0042] Reference Figure 8 , Fig. 9 The inlet conveyor 3 includes an independently operated and connected conveying section 31 and a buffer section 32, and the buffer section 32 is docked with the cargo of the elevator trolley 13. The conveying section 31 and the buffer section 32 are both configured as belt conveyors, and the conveying speeds of the two and the speed difference between the two are set according to the actual application. In addition, the outlet conveyor 4 is also configured as a belt conveyor.

[0043] Continue to refer to Figure 6 , Figure 7 Further, the first flexible member 11 and the second flexible member 12 are both provided in pairs, the two first flexible members 11 are provided in a positional relationship side by side, the two second flexible members 12 are provided in a positional relationship side by side, the first flexible member 11 and the second flexible member 12 which are closest to each other form a group of transmission mechanisms, and the two groups of transmission mechanisms are in a mirror-symmetrical relationship, referring to Figure 3 , the spacing between the two first flexible members 11 is greater than the spacing between the two second flexible members 12, and vice versa. The hoist trolley 13 is movably connected to the two first flexible members 11 and the two second flexible members 12 at the same time, that is, the hoist trolley 13 is supported by four connection points to improve its stability during movement, maintain a horizontal state and avoid tilting. In addition, the rectangular projection surface formed by the first flexible member 11 and the second flexible member 12 partially overlaps. Since the first flexible member 11 and the second flexible member 12 of the same group of transmission mechanisms are spaced apart, the setting of partially overlapping projection surfaces will not cause mechanical interference problems, and can also compress the space volume occupied by the continuous hoist 1, so that the continuous hoist has a reasonable and compact structure.

[0044] Among all the transmission wheels corresponding to the first flexible member 11 and the second flexible member 12, any one is selected as the driving wheel, and all the other transmission wheels are driven wheels. In this embodiment, the hoist frame 10 is fixedly mounted with a motor 14, and one of the transmission wheels of the second flexible member 12 is used as a driving wheel 120-1 and is assembled on the motor 14. In addition, at least one of the transmission wheels corresponding to the first flexible member 11 is a tensioning wheel 110-A with adjustable position, and at least one of the transmission wheels corresponding to the second flexible member 12 is a tensioning wheel 120-A with adjustable position, and the stability of the operation of the hoist trolley 13 can be improved by adjusting the tension of the first flexible member 11 and the second flexible member 12.

[0045] Reference Fig.10 , Fig.11The hoist trolley 13 includes a frame 131 and a flow-dividing bearing part 132. The flow-dividing bearing part 132 is horizontal and fixedly connected to the frame 131. The frame 131 has four horizontally arranged axes perpendicular to the plane where the first flexible member 11 and the second flexible member 12 are located, and are respectively movably connected to the two first flexible members 11 and the second flexible member 12. Specifically, the four axes of the frame 131 are combined with the first flexible member 11 and the second flexible member 12 and can rotate around their central axis, that is, when the hoist trolley 13 moves and turns, the four axes rotate relative to the first flexible member 11 and the second flexible member 12, so that the hoist trolley 13 always maintains a horizontal state. More specifically, the first flexible member 11 and the second flexible member 12 are chains, and the corresponding transmission wheels 110 and 120 are sprockets. The axis of the frame 131 is perpendicular to the plane where the first flexible member 11 and the second flexible member 12 are located, and the chain link of the chain is slidably sleeved on the axis. First, compared with other transmission methods, this implementation case uses chain transmission, which has no elastic sliding and slipping phenomenon, and the average transmission ratio is more accurate, which meets the requirements of accurate movement of the hoist trolley, has better operating reliability and high efficiency; it has large power transmission, strong overload capacity, and low restrictions on cargo weight. Secondly, the active connection between the chain and the frame shaft is more stable. When the hoist trolley moves and turns, the shaft rotates relative to the chain, and the transition is smooth and not easy to shake. In this process, the friction between the shaft and the chain is small, and the loss of transmission force is relatively low.

[0046] Further, the vehicle frame 131 includes a first connecting shaft 1311, two second connecting shafts 1312 and two connecting rods 1313, the two ends of the first connecting shaft 1311 are respectively vertically fixedly connected to one end of the two connecting rods 1313, the other end of the connecting rod 1313 is vertically fixedly connected to the second connecting shaft 1312, the chain links of the two first flexible members 11 are slidably sleeved on the first connecting shaft 1311 and the two first flexible members 11 are symmetrically located with respect to the first connecting shaft 1311, and the chain links of the two second flexible members 12 are respectively slidably sleeved on the two second connecting shafts 1312. The vehicle frame 131 composed of the first connecting shaft 1311, the two second connecting shafts 1312 and the two connecting rods 1313 is a U-shaped structure, the flow diversion bearing portion 132 is located at the center of the U-shaped structure, and is fixedly connected to the first connecting shaft 1311 via two support rods 1314. The U-shaped structure of the frame 131 makes its overall structure have strong rigidity, so the installation and fixing environment of the diverter bearing part 132 is relatively stable, and the four connection positions of the frame 131 with the first flexible member 11 and the second flexible member 12 are respectively located at the two end positions of the U-shaped structure and two positions close to the turning, that is, the four connection positions are all located in the main part of the U-shaped structure. On the one hand, the actual force difference between the four connection positions is small, and the weight distribution of the hoist trolley 13 is relatively balanced, which can keep the hoist trolley 13 in a horizontal state as a whole without tilting. On the other hand, the loss degree of the first flexible member 11, the second flexible member 12, the first connecting shaft 1311, and the second connecting shaft 1312 is not much different, thereby avoiding the imbalance of the hoist trolley 13 caused by excessive local loss.

[0047] The diversion bearing part 132 is configured as a belt conveyor and is driven by a motor 133. The belt conveyor can run in both directions. When the elevator trolley 13 is docked with the goods on the outlet conveying path 4, the belt conveyor is running, and the goods fall from the elevator trolley 13 to the outlet conveying path 4. In addition, when the elevator trolley 13 is docked with the goods on the entrance conveying path 3, after receiving the goods dropped from the entrance conveying path 3 to the elevator trolley 13, the belt conveyor can be operated to adjust the position of the goods on the elevator trolley 13. On the one hand, the center of gravity of the goods and the elevator trolley 13 can be kept stable. On the other hand, the position of the goods can be fine-tuned to prepare for docking with the goods on the outlet conveying path 4.

[0048] Reference Figure 10-12 Combined with Figure 6 , Figure 7The hoist trolley 13 also includes a power supply busbar 15, which is fixedly installed in the hoist frame 10 and is roughly in the shape of a closed rectangle. It is the same shape as the first flexible member 11 and the second flexible member 12 and is slightly larger than both. The power supply busbar 15 is coplanar with any one of the first flexible members 11 or the second flexible member 12 and is arranged on its periphery. Specifically in this embodiment, the power supply busbar 15 is coplanar with one of the second flexible members 12 and is arranged on its periphery, and the distance from any point of the power supply busbar 15 to the second flexible member 12 is the same. The frame 131 of the hoist trolley 13 is provided with a power brush 16, which is movably connected to the frame and can rotate in the plane where the power supply busbar 15 is located, and the power brush 16 is in sliding contact with the power supply busbar 15. The frame 131 of the hoist trolley 13 is also provided with a conductive slip ring 17, and the power brush 16 draws electricity from the power supply busbar 15 through the conductive slip ring 17 to supply the hoist trolley 13. Specifically, the power brush 16 includes a connecting portion 161 and a brush portion 162, which are fixedly connected, the connecting portion 161 is slidably sleeved on the first connecting shaft 1311 of the frame 131, the brush portion 162 is in sliding contact with the power supply busbar 15, and the conductive slip ring 17 is sleeved and installed on the first connecting shaft 1311, and connects the power brush 16 and the motor 133 of the belt conveyor.

[0049] The hoist trolley 13 moves along its path, and the power brush 16 also slides on the power supply busbar 15. When the hoist trolley 13 turns, for example, from the left vertical ascending path to the upper horizontal rightward moving path, the connecting portion 161 of the power brush 16 rotates relative to the first connecting shaft 1311 so that the brush portion 162 always maintains a stable sliding contact state with the power supply busbar 15, that is, when the hoist trolley 13 moves along its moving path, the power brush 16 can always maintain a state of power supply, and the hoist trolley 13 will not experience power interruption, nor will the power supply be unstable due to its turning. In addition, the power brush 16 is set as two parts that are in sliding contact with the power supply busbar 15 as a preferred solution. These two parts and the connecting portion 161 form a Y-shaped overall structure with good support, which improves the stability of the power brush 16 sliding on the power supply busbar 15 with the hoist trolley 13 to obtain a stable power transmission state.

[0050] Reference Figure 1 , Fig.13 The sorting machine 2 includes a sorting machine frame 20 and a multi-layer sorting conveyor 21. The sorting conveyor 21 is a long structure and is arranged in layers in the sorting machine frame 20. It can be set to a straight line or a curved shape according to the actual site. It corresponds to the outlet conveyor 4 one by one and the goods are docked. In the first implementation case, for example Fig.14As shown, the docking position between the sorting conveying path 21 and the outlet conveying path 4 is the end of the outlet conveying path 4. In the second implementation case, as shown in FIG. Fig.15 As shown, the docking position of the sorting conveying path 21 and the outlet conveying path 4 is any position in the middle of the outlet conveying path 4. A plurality of grid openings 22 are provided along the length direction of each layer of the sorting conveying path 21 on one side or both sides thereof, and the grid openings 22 are docked with the goods on the sorting conveying path 21. A reciprocating trolley 23 is provided on each layer of the sorting conveying path 21, and the reciprocating trolley 23 can reciprocate along the length direction of the sorting conveying path 21 and dock with the goods on the outlet conveying path 4 and the grid openings 22.

[0051] The sorting machine of the prior art also has a multi-layer structure, in which a trolley is arranged. The trolley is moved to other levels by changing tracks. The moving tracks of different trolleys must have overlapping parts. Therefore, the sorting order needs to be set during sorting to avoid the occurrence of collisions, and the sorting logic is relatively complex. In addition, the distance between the trolley receiving the goods and the lattice delivering the goods is not the shortest straight distance, and because the logic setting requires the trolley to slow down or even stop to avoid collisions, its sorting efficiency is relatively low. The present invention solves the above problem. Therefore, for the present invention, the distance for the reciprocating trolley 23 to transport the goods is the shortest straight distance, and there is no need to consider the collision phenomenon. The efficiency of the sorting mode is greatly improved compared with the prior art. From another perspective, increasing the moving speed of the reciprocating trolley 23 on the sorting conveyor 21 can further improve the sorting efficiency on the basis of the optimized sorting mode.

[0052] Reference Fig.13 , 16 Combined with Figure 1 Therefore, further, the sorting conveying path 21 includes two parallel tracks 211 and a transmission mechanism. The tracks 211 are arranged along the length direction of the sorting conveying path 21. The reciprocating trolley 23 is arranged on the tracks 211 and is driven to reciprocate by the transmission mechanism. Specifically, the reciprocating trolley 23 includes a frame 231 and a sorting bearing part 232. Four running wheels 2311 running on the tracks 211 are installed at the bottom of the frame 231. Compared with the prior art, the friction resistance during running is small, and the reciprocating trolley 23 can run at high speed along the tracks 211. The transmission mechanism includes a synchronous belt 241, two transmission shafts 242 and a motor 243. The two transmission shafts 242 are respectively arranged at the two ends of the sorting conveying path 21. The synchronous belt 241 is arranged along the length direction of the sorting conveying path 21. It is connected by the two transmission shafts 242. One of the transmission shafts 242 is driven by the motor 243. The frame 231 of the reciprocating trolley 23 is fixedly connected to the synchronous belt 241.

[0053] Furthermore, the synchronous belt 241 is disconnected, and its width is smaller than the width of the frame 231. The front end and the rear end of the frame 231 are respectively fixedly connected to the two ends of the disconnected synchronous belt 241. Specifically, the front end and the rear end of the frame 231 are respectively provided with clamping blocks 2312 for clamping and fixing the two ends of the synchronous belt 241. This arrangement is relatively convenient to install and is also convenient for adjusting the tension of the synchronous belt 241. Therefore, in actual application, the length calculation of the synchronous belt 241 does not need to be too precise and can be solved by fine-tuning, which is convenient for maintenance or replacement of the reciprocating trolley 23.

[0054] In addition, in order to improve the stability of the reciprocating trolley 23 running on the track 211, at least one guide wheel 2313 is installed at the bottom of the frame 231 corresponding to each track 211, and the guide wheel 2313 is slidably matched with the inner side surface of the corresponding track 211. Preferably, two guide wheels 2313 are installed respectively, and the positions of the four guide wheels 2313 correspond to the four walking wheels 2311 one by one.

[0055] The sorting carrying part 232 is configured as a belt conveyor that can run in both directions, and the conveying direction of the belt conveyor is perpendicular to the moving direction of the reciprocating trolley 23. When the reciprocating trolley 23 moves and stops at the corresponding grid 22, the belt conveyor starts to push the loaded goods to the corresponding grid 22 to complete the docking of the goods. In addition, the belt conveyor is powered by a drag chain (not shown in the figure) arranged on the sorting conveying path 21.

[0056] Taking into account that the reciprocating trolley 23 of the present invention has a relatively fast moving speed and a relatively large inertia when starting or stopping, in order to prevent the goods from falling off the sorting carrying part 232 due to inertia, the frame 231 of the reciprocating trolley 23 is respectively provided with baffles 2314 higher than the sorting carrying part 232 at the front and rear ends. The two baffles 2314 limit the goods within the loading range of the diversion carrying part 132, thereby avoiding the above situation.

[0057] For the grid 22, in the first implementation case, if Fig.17 As shown, the plurality of grids 22 located on the same side of the sorting conveying path and in an upper and lower position relationship correspond to different destinations respectively, and can cope with general sorting situations. Fig.18 As shown, the plurality of grids 22 located on the same side of the sorting conveying path and in an upper and lower position relationship correspond to the same destination. This approach can improve the sorting efficiency of a large number of goods with the same destination.

[0058] Finally, it should be noted that the above implementation cases are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned implementation cases, those skilled in the art should understand that they can still modify the technical solutions recorded in the aforementioned implementation cases, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the implementation cases of the present invention.
