[0002] At present, the sorting robots on the market are tipping robots or belt robots. The tipping robots can only deliver on one side, with low efficiency. Although the belt sorting robots can deliver on both sides, the cost is relatively high.

[0003] Most of the delivery forms of sorting robots are to carry goods such as boxes, parcels, and boxes for handling work. In this way, the sorting robots have a need for automatic and rapid delivery or unloading. However, the single-side delivery of the tipping robots cannot meet the requirements of the delivery task. Only by adding tipping robots with different-side deliveries can the function of different-side deliveries be realized, which greatly increases the operation cost. In addition, although the belt robots can achieve double-side delivery, the cost is also very high. At the same time, the structure is complex and the failure rate is high, causing unnecessary losses to the daily parcel delivery.

[0004] Therefore, how to improve the delivery efficiency of the delivery system is a technical problem that needs to be solved urgently by those skilled in the art. Summary of the Invention

Specific embodiment

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figure 1 , Figure 1 is the schematic overall structure diagram of a specific embodiment provided by the present invention. Among them, the arrows in the accompanying drawings represent the moving direction or the transport path.

[0032] In a specific embodiment provided by the present invention, the logistics system mainly includes: a dispatch control device 1 for controlling the transport robot 2 to perform transport and delivery operations; a transport robot 2 for performing transport and delivery operations according to the instructions of the dispatch control device 1; a loading device 3 having a plurality of loaders for obtaining the position information of the packages, and the loaders send the package position information to the dispatch control device 1; a sorting platform 4 having a plurality of lanes for the transport robot 2 to walk and a plurality of goods collection devices distributed on both sides of a single lane for collecting packages. The dispatch control device 1 controls the transport robot 2 to move to the goods collection device corresponding to the package position information. The transport robot 2 can perform package delivery by flipping the two side flaps, and a loading device 3 is provided at the end of a single lane (A, B, C, D, E, F, etc. in the accompanying drawings represent the loading points corresponding to the loading device 3).

[0033] Among them, the dispatch control device 1 is communicatively connected to the transport robot 2 and the loading device 3 through a wired connection or a wireless connection method, and is used to control the movement of the transport robot 2 and control the loading device 3 to perform package identification. The transport robot 2 is arranged on the lane of the sorting platform 4 and is used to collect packages and deliver the packages to the goods collection device of the sorting platform 4.

[0034] Specifically, as Figure 1 shown in the sorting scenario layout, the compartments or cage trucks 1-10 of the sorting platform 4 represent different parcel destinations. All destination compartments are divided into two rows and arranged at intervals of lanes with substantially the same width, that is, any two adjacent rows of cage truck compartments or compartments contain all destinations. Loading points are provided at both ends of each first lane. One or more channels can be provided horizontally between the loading point and the sorting platform 4. The multiple channels are used for the transportation robot 2 to directly drive to the loading point after delivering the parcel. Generally, the nearest loading point will be selected. In addition, as Figure 2 shown in the sorting scenario layout of the multi-layer platform is the same as that of the single-layer platform. The difference is that only the cage trucks are placed on the lower layer and the upper layer corresponds to the compartments. The difference from the existing multi-layer platform sorting scenario is that there is no lane provided horizontally between the cage truck / compartment, and only a one-way lane is provided vertically. More cage trucks / compartments can be arranged, the site utilization rate is improved, and the transportation robot 2 can deliver from both sides.

[0035] In the actual application process, when the on-site production operation starts, the dispatching control device 1 dispatches the transportation robot 2 without tasks to the loading device 3 to wait for loading; then, the operator or automated equipment picks up the parcel at the position of the loading device 3 through the loader and performs scanning and identification. The dispatching control device 1 queries the delivery destination of the parcel. The loading device 3 places the parcel on the transportation robot 2 through the loader. At this time, the dispatching control device 1 issues an operation instruction to the transportation robot 2 and generates a delivery task to reach the destination compartment corresponding to the corresponding parcel. For example, as Figure 1 shown, the transportation robot 2 drives to the loading device 3 at the loading point A to obtain the parcel. After identifying that the parcel is an item destined for the 4th cage truck / compartment, the transportation robot 2 drives to the lane opposite to the loading point A. Assuming the direction of driving to the loading point A is the first channel and the reverse lane is the second channel, when the transportation robot 2 moves to the position where the cage truck / compartment 4 is located, the parcel is turned over and delivered to the left. If the destination is 9, the goods are delivered and turned over to the right. After the delivery is completed, the transportation robot 2 continues to drive forward with an empty vehicle. The dispatching control device 1 selects the other loading point at the other end in front according to the order task, usually giving priority to the nearest loading point D. If there is no work task at the loading point D, the trolley drives to other loading points near D. The transportation robot 2 obtains the task parcel at the loading point D. The transportation robot 2 can turn in both directions, drives to the second channel near the loading point, and the transportation robot 2 will execute according to the task assigned by the dispatching control device 1 to complete the parcel delivery task. After the delivery is completed, the transportation robot 2 drives to the other end loading point and waits for the next sorting task.

[0036] To optimize the advantage that the logistics system in the above embodiments can more efficiently complete the package delivery task, the lanes are all one-way lanes. Since there may be multiple transportation robots 2 in the logistics system, and there may also be multiple loading points, and the delivery tasks are executed simultaneously. Therefore, during the package delivery task, to avoid the possible collision of the transportation robots 2, the lanes of the transportation robots 2 are set as one-way lanes. In this way, it can be ensured that during the delivery process of the transportation robots 2, the situation of driving towards each other is avoided, ensuring the inevitable success of each package delivery by the transportation robots 2 and enhancing the efficiency of package delivery.

[0037] It should be noted that the directions of adjacent lanes are different. Assuming that the directions of adjacent lanes are the same. For example, as Figure 1 shown, the directions of the two adjacent lanes of loading point A and loading point D are the same. When the transportation robot 2 completes the delivery task at loading point A and drives towards loading point D, at this time, since the directions of the two adjacent lanes are the same, the transportation robot 2 will not be able to reach the position of the four cage cars on the left and cannot complete the delivery task. Therefore, only by setting the directions of adjacent lanes to be opposite can the delivery task be achieved. The above design ensures that the transportation robot 2 can have a circular driving path, ensuring the feasibility of the delivery task. At the same time, the fastest delivery path can be achieved, ensuring the efficiency of package delivery.

[0038] Furthermore, the lane can accommodate at least one transportation robot 2 to move. During the actual package delivery task process, for example, assuming that the transportation robot 2 starts the delivery task from loading point A. When a transportation robot 2 is performing the delivery task, the transportation robot 2 picks up the package from loading point A and then drives towards the upper delivery point. At this time, if another package delivery task starts at loading point A, at this time, the transportation robot 2 driving upwards is relatively far from loading point A. If another transportation robot 2 is near loading point A at this time, it can continue to pick up the package and follow the previous transportation robot 2 to perform the delivery task. The reason for setting the lane to accommodate at least one transportation robot 2 to move is that when the previous transportation robot 2 is performing the delivery, the next delivery transportation robot 2 is very likely to drive up. The above design can ensure that when the previous transportation robot 2 is performing the delivery, the next transportation robot 2 can continue to drive forward without affecting the delivery task of the next transportation robot 2, ensuring that the delivery task will not terminate and improving the efficiency of package delivery.

[0039] It should also be noted that feeding devices 3 are respectively arranged at both ends of a single lane. The design of multiple feeding devices 3 ensures that multiple transport robots 2 can perform delivery tasks at the same time. After a transport robot 2 completes a delivery task, the scheduling and control device 1 selects the feeding point at the other end in front according to the order task, usually giving priority to the nearest feeding point D. If there is no task at the feeding point D, the trolley drives to other feeding points near D. The transport robot 2 obtains the task package at the feeding point D. The transport robot 2 can turn in both directions and drive towards the second passage near the feeding point. The transport robot 2 will execute the task assigned by the scheduling and control device 1 to complete the package delivery task. After the delivery is completed, the transport robot 2 drives to the feeding point at the other end and waits for the next sorting task, improving the efficiency of package delivery.

[0040] Please refer to Figure 3 and Figure 4 , Figure 3 is Figure 1 the schematic structural diagram of the transport robot shown; Figure 4 is Figure 3 the schematic internal structure diagram of the transport robot shown.

[0041] The transport robot 2 includes a first driving device 201, a second driving device 202, a first connecting member 203, a second connecting member 204 and a load platform 205. Both ends of the first connecting member 203 are respectively hinged to the first driving device 201 and the lower surface of the load platform 205. Both ends of the second connecting member 204 are respectively hinged to the second driving device 202 and the lower surface of the load platform 205. The first connecting member 203 and the second connecting member 204 are respectively located on both sides of the center line of the load platform 205. Both the first driving device 201 and the second driving device 202 are located below the load platform 205. Since when the transport robot 2 performs the package delivery task, the delivery method of the transport robot 2 is the left flap delivery and the right flap delivery methods. Therefore, in order to ensure the realization of the above functions, the transport robot 2 is provided with the first driving device 201, the second driving device 202, the first connecting member 203, the second connecting member 204 and the load platform 205. When left flap delivery is required, the second driving device 202 drives the second connecting member 204 to move upward, thereby lifting the right side of the load platform 205, so that the package above the load platform 205 is bounced to the left, realizing left flap delivery; when right flap delivery is required, the first driving device 201 drives the first connecting member 203 to move upward, thereby lifting the left side of the load platform 205, so that the package above the load platform 205 is bounced to the right, realizing right flap delivery. Therefore, combining the above logistics system and the left flap delivery and right flap delivery methods of the transport robot 2, the method of realizing two-sided flap delivery by the same transport robot 2 is realized, avoiding the drawback that the existing transport robot 2 can only deliver goods unidirectionally, ensuring the rapid execution of the nearby delivery task, avoiding the need to use transport robots 2 with different flap delivery methods for separate-direction delivery, and improving the execution efficiency of delivering packages. It should be noted that both the first driving device 201 and the second driving device 202 are electric cylinders.

[0042] It should be noted that the lower surface of the load platform 205 is provided with a first connecting portion and a second connecting portion. The first connecting portion is hinged to the first connecting member 203, and the second connecting portion is hinged to the second connecting member 204. Since the transport robot 2 provided by this solution can achieve left-side flap delivery and right-side flap delivery simultaneously, the first driving device 201, the second driving device 202, the first connecting member 203, and the second connecting member 204 also perform a large number of actions. In order to better enable the first driving device 201, the second driving device 202, the first connecting member 203, and the second connecting member 204 to play their roles, by hinging the first connecting portion to the first connecting member 203 and the second connecting portion to the second connecting member 204, the connection strength between the first driving device 201 and the first connecting member 203, and between the second driving device 202 and the second connecting member 204 can be ensured, and the service life of the first driving device 201, the second driving device 202, the first connecting member 203, and the second connecting member 204 can be increased.

[0043] Furthermore, the transport robot 2 further includes a first support frame 206 for supporting the first connecting portion and a second support frame 207 for supporting the second connecting portion. The top end faces of the first support frame 206 and the second support frame 207 are both flat surfaces, and the bottoms of the first connecting portion and the second connecting portion are both arc surfaces. Because when the load platform 205 performs left-side flap delivery and right-side flap delivery actions, the left or right side of the load platform 205 rotates. Therefore, by setting the bottoms of the first connecting portion and the second connecting portion as arc surfaces, the purpose of the end-side rotation of the load platform 205 is achieved, and the left-side flap delivery and right-side flap delivery actions are realized, further reducing the wear on other components during the left-side flap delivery and right-side flap delivery actions of the load platform 205 and improving the service life of the transport robot 2.

[0044] It should be noted that an arc-shaped edge is provided circumferentially on the load platform 205. During the driving process of the transport robot 2, due to friction and collision, the packages on the load platform 205 may be impacted, resulting in the packages falling off. The above design can prevent the packages from falling out of the load platform 205 when being impacted, ensure the safe arrival of the packages at the delivery destination, and achieve high-efficiency delivery.

[0045] Please refer to Figure 5 , Figure 5 which is a schematic flowchart of a specific implementation manner provided by the present invention.

[0046] This application also provides a logistics scheduling method, which is applied to the above logistics system and includes:

[0047] S1: Control the transport robot 2 to move to the position of the feeder, and obtain the position information of the package and the destination position corresponding to the package position information;

[0048] Specifically, the scheduling control device 1 controls the transport robot 2 to move to the feeder position, and obtains the position information of the package and the destination position corresponding to the package position information through the feeder. It should be noted that obtaining the package information can include the operator taking the package at the feeder position of the feeding device 3 for scanning and identification, or the automated device taking the package at the feeder position of the feeding device 3 for scanning and identification.

[0049] S2: Generate a delivery task according to the position information and the destination position;

[0050] Specifically, the scheduling control device 1 generates a delivery task according to the package position information and the destination position, and sends the delivery task to the transport robot 2.

[0051] S3: Control the transport robot 2 to move the package unidirectionally along the first channel and deliver it into the collecting device corresponding to the destination position.

[0052] Specifically, the scheduling control device 1 controls the transport robot 2 to move the package unidirectionally along the first channel and deliver it into the collecting device corresponding to the destination position.

[0053] The transport robot 2 moves unidirectionally through the second channel to the position of the next feeder.

[0054] By combining this method with the above-mentioned logistics system, the package delivery structure can be optimized. The fast delivery is realized through the double-sided flap transport robot, and the operation efficiency is improved. In addition, the same transport robot realizes double-sided delivery, reducing the failure rate at the same time and improving the operation efficiency.

[0055] In summary, the logistics system provided by this embodiment mainly includes a scheduling control device for controlling the transportation robot to perform transportation and delivery operations; a transportation robot for performing transportation and delivery operations according to the instructions of the scheduling control device; a loading device having a plurality of loaders for obtaining the position information of the packages, and the loaders send the package position information to the scheduling control device; a sorting platform having a plurality of lanes for the transportation robot to walk and a plurality of goods collection devices distributed on both sides of a single lane for collecting packages. The scheduling control device controls the transportation robot to move to the goods collection device corresponding to the package position information. The transportation robot can perform package delivery with double-sided flaps, and a loading device is provided at the end of a single lane. By setting the delivery robot to perform double-sided flap delivery, one robot can complete double-sided delivery operations, improving the delivery efficiency. At the same time, the operation structure can be optimized, the delivery failure rate can be reduced, and the operation cost can be lowered. The present application also provides a logistics scheduling method applied to the above logistics system, including: controlling the transportation robot to move to the position of the loader, obtaining the position information of the package and the destination position corresponding to the package position information; generating a delivery task according to the position information and the destination position; and controlling the transportation robot to move the package unidirectionally along the first channel and deliver it into the goods collection device corresponding to the destination position. Fast delivery is achieved through the double-sided flap transportation robot, improving the operation efficiency. In addition, the same transportation robot realizes double-sided delivery, reducing the failure rate at the same time and improving the operation efficiency.
