However, this method lacks intelligence and flexibility, and cannot be adjusted in real time according to the actual situation of the express items. It has problems such as high labor costs and limited sorting accuracy. Some other high-precision sorting methods use complex mechanical structures or multi-wheel coordinated steering to achieve lane separation of items.

[0030] The present application provides a lane control system based on a single turntable and a control method thereof. In order to make the purpose, technical solution and advantages of the present application clearer, the implementation method of the present application will be further described in detail below.

[0031] The following is a further detailed description of an embodiment of a lane control system based on a single turntable and a control method thereof according to the present application in conjunction with the accompanying drawings of the specification.

[0032] Embodiment 1: The present embodiment discloses a lane control system based on a single turntable, including a feed channel 1, a carrying plate 2 for carrying objects to be laned, a lane turntable 3 for diverting the objects to be laned, and a first driving member for driving the lane turntable 3. The carrying plate 2 is fixedly connected to the feed channel 1. The carrying plate 2 in the present embodiment is circular.

[0033] like Figure 1 As shown, the supporting plate 2 is annular, the lane turntable 3 is located at the center of the supporting plate 2 and the upper surfaces of the two are flush, and the edge of the lane turntable 3 is gap-matched with the inner ring edge of the supporting plate 2 to prevent the rotation of the lane turntable 3 from being obstructed.

[0034] A plurality of passages 4 are arranged around the outer ring of the carrier plate 2 , and each object to be sorted corresponds to a passage 4 .

[0035] An identification device 5 is provided above the feed channel 1 . The identification device 5 and the first driving member are electrically connected to a control system. The control system is used to control the first driving member to drive the lane turntable 3 to rotate.

[0036] The height of the carrying plate 2 is lower than that of the feeding channel 1 , so as to ensure that the objects can be smoothly transferred from the feeding channel 1 to the carrying plate 2 .

[0037] The height of each channel 4 is lower than that of the carrier plate 2 , which helps the items to slide smoothly into the destination channel 4 and complete the sorting process.

[0038] Conveyor belts are provided on both the feed channel 1 and the destination channel 4 .

[0039] A monitoring device is provided above the channel 4 of each item, which can monitor the load condition of the destination channel 4 in real time and provide important feedback data to the control system to ensure the efficiency and stability of the sorting process.

[0040] In this embodiment, the feed channel 1 is responsible for introducing the objects to be sorted into the system's carrier plate 2, and the identification device 5 arranged above it can quickly and accurately read the information on the objects, such as barcodes, QR codes, etc., to determine the destination channel 4 of the objects.

[0041] The identification device 5 in this embodiment is a photoelectric sensor, which uses precise barcode, QR code, RFID or optical character recognition OCR technology to ensure that each item is accurately identified and directed to the correct channel before entering the lane turntable 3.

[0042] As the core component of the system, the lane-dividing turntable 3 carries the objects to be divided into lanes and rotates accurately according to the command of the control system to realize the lane-dividing and turning of the objects. The first driving member is responsible for providing power to the lane-dividing turntable 3 to ensure that it can rotate smoothly according to the command.

[0043] A first pushing component is arranged on the lane turntable 3, and the first pushing component is driven by a second driving component, and the second driving component is electrically connected to the control system.

[0044] The first pushing component is used to push the objects on the lane turntable 3 onto the carrying plate 2 .

[0045] In this embodiment, if Figure 1 As shown, the first pushing assembly includes a plurality of first rollers 6 arranged in parallel, and the plurality of first rollers 6 are evenly distributed on the lane turntable 3 with the same distance therebetween and protrude from the upper surface of the lane turntable 3 .

[0046] A plurality of groups of second pushing components are arranged on the carrier plate 2. The second pushing components are driven by a third driving member, and the third driving member is electrically connected to the control system.

[0047] The second pushing component is used to push the objects on the carrying plate 2 pushed by the lane turntable 3 to the corresponding destination channel 4.

[0048] A plurality of channels 4 are arranged around the carrier plate 2 , and a group of second pushing components is correspondingly arranged at the entrance of each channel 4 .

[0049] Each group of second pushing components includes a plurality of second rollers 7 arranged in parallel. The second rollers 7 belonging to the same group are distributed between the edge of the lane turntable 3 and the entrance of the corresponding destination channel 4 at the same interval and protrude from the upper surface of the carrier plate 2.

[0050] A third pushing component is also provided on the carrier plate 2 . The third pushing component is driven by a fourth driving component. The fourth driving component is electrically connected to the control system.

[0051] The third pushing component is used to push the objects coming out of the feeding channel 1 onto the lane dividing turntable 3, and then the lane dividing turntable 3 performs the lane dividing operation.

[0052] The third pushing assembly includes a plurality of third rollers 8 arranged in parallel, which are distributed at the same distance between the edge of the lane turntable 3 and the outlet 9 of the feed channel 1 and protrude from the upper surface of the supporting plate 2. All rollers in this embodiment have the same specifications.

[0053] In this embodiment, when the object to be divided into lanes passes through the feed channel 1, the identification device 5 will immediately read the information on the object and transmit it to the control system. The control system obtains the destination channel 4 of the object, and the control system quickly calculates the angle and direction that the lane dividing turntable 3 needs to rotate according to the preset lane dividing parameters and the destination channel 4, and generates corresponding control instructions.

[0054] After the laned items pass through the third push assembly on the carrier plate 2 and arrive at the lane turntable 3, the driving member will immediately drive the lane turntable 3 to rotate until it reaches the calculated position. At this time, the control system will control the first push assembly to accurately push the items onto the second push assembly on the carrier plate 2, and the second push assembly will push the items into the corresponding destination channel 4 to complete the entire sorting process.

[0055] This single turntable-based lane control system not only has a simple structure and is easy to maintain, but is also highly intelligent and automated, and can significantly improve the efficiency and accuracy of logistics sorting.

[0056] Embodiment 2: This embodiment discloses a lane control method based on a single turntable, which further refines the generation process of control instructions based on the lane control system of Embodiment 1.

[0057] A lane control method based on a single turntable, such as Figure 2 As shown, the following steps are included: S1. Construct a plane rectangular coordinate system in the system to set and calibrate lane parameters, which include the center coordinates of the lane turntable 3, the coordinates of the entrance center of each destination channel 4, and the initial position set for the lane turntable 3.

[0058] S2, obtaining the destination channel 4 corresponding to the object to be separated, combining the lane parameters, generating the corresponding control instructions for the object to be separated, and controlling the lane separation turntable 3 to rotate according to the control instructions, specifically including the following steps: S21. When the objects to be separated into lanes are placed on the conveyor belt of the feeding channel 1 for transportation, the identification device 5 above the feeding channel 1 is used to identify the information on the objects to be separated into lanes to obtain an identification result.

[0059] The photoelectric sensor can accurately identify the items to be separated, such as scanning the barcode or QR code to obtain the category, destination and other information of the items. This information provides an important data basis for subsequent lane control.

[0060] S22 . Obtain the destination channel 4 corresponding to the current object to be separated according to the recognition result. Each object to be separated has a corresponding destination channel 4 .

[0061] S23, determining the first coordinate of the entrance center corresponding to the object to be laned according to the lane separation parameters and the destination channel 4 corresponding to the object to be laned.

[0062] The coordinates of the entrance center of the current destination channel 4 can be obtained according to the coordinates of the entrance center of each destination channel 4 and the destination channel 4 of the current object to be separated.

[0063] S24, obtaining the offset angle of the current lane turntable 3 relative to the preset initial position, thereby obtaining the current pushing direction of the lane turntable 3.

[0064] In this embodiment, the offset angle has positive and negative angles. The initial position is set to zero degrees, the offset to the left from the initial position is a negative angle, and the offset to the right from the initial position is a positive angle. The initial position and the offset angle are added to obtain the current position of the lane turntable 3.

[0065] When the lane turntable 3 is located at the current position, the rotation direction of the first roller 6 of the first pushing assembly thereon is the pushing direction. In this embodiment, the rotation directions of all rollers are fixed.

[0066] S25. Obtain the direction of the line from the center position of the lane turntable 3 to the entrance center of the current destination channel 4 according to the first coordinate, and use the direction of the line as the target pushing direction of the lane turntable 3.

[0067] The first coordinate is the position of the center of the entrance of the destination channel 4 of the current object to be separated. Connecting the center position of the lane dividing turntable with the center position of the entrance of the destination channel 4 is the final pushing route of the current object to be separated. The direction of the destination channel 4 pointed by this route is also the direction in which the object needs to be pushed in the end.

[0068] S26, calculating the first minimum angle between the current pushing direction and the target pushing direction, generating a control instruction according to the first minimum angle, so that the lane turntable 3 rotates according to the control instruction, and the control instruction includes a rotation angle and a rotation direction.

[0069] S3: Determine whether the item can be pushed into the destination channel 4 according to the load flow of the destination channel 4. The process is as follows: Figure 3 As shown, the specific steps include the following steps.

[0070] S31. Obtain the load flow of the current destination channel 4 according to the monitoring device above the current destination channel 4, and compare the load flow with a preset load threshold.

[0071] S32: When the load flow of the destination channel 4 does not exceed the preset load threshold, it is determined that the item can be pushed into the destination channel 4.

[0072] S33. When the load flow exceeds the preset load threshold, the item cannot be pushed into the destination channel 4. At this time, the cache load flow of the preset cache channel is obtained.

[0073] When the load flow exceeds the load threshold, it indicates that the destination channel 4 is blocked. If the items are still pushed to the destination channel 4 at this time, the blockage will be aggravated. At this time, it is necessary to consider whether to push to the preset cache channel.

[0074] The cache channel is used to store items that cannot be transported into the destination channel 4 in time when the destination channel 4 is overloaded, so as to avoid lane confusion and system errors caused by the accumulation of items on the lane turntable 3 that cannot be transported into the destination channel 4. In this embodiment, any one of the destination channels 4 is set as a cache channel, which is not marked in the figure.

[0075] S34: Compare the cache load flow with a preset cache load threshold.

[0076] S341. When the cache load flow does not exceed the preset cache load threshold, the item is pushed into the cache channel.

[0077] The second coordinate of the entrance center of the cache channel is obtained, and the cache direction from the center position of the lane dividing turntable 3 to the second coordinate is obtained.

[0078] The second minimum angle between the current push direction and the cache direction is calculated, and a cache lane instruction is generated according to the second minimum angle, and the lane turntable 3 is controlled to rotate according to the cache lane instruction. The cache lane instruction includes a rotation angle and a rotation direction.

[0079] The principles of the above steps are the same as those of steps S25 and S26, and will not be repeated here.

[0080] S342: When the load flow of destination channel 4 exceeds the load threshold and the cache load flow of the cache channel exceeds the cache load threshold, both destination channel 4 and the cache channel are blocked and no further push is performed.

[0081] In this embodiment, the objects to be separated into lanes are transferred out from the outlet 9 of the feed channel 1 and fall onto the third pushing assembly on the carrying plate 2 .

[0082] When any one of the cache channel and the destination channel is not blocked, the control system controls the fourth driving member to drive the third pushing assembly, so that the third roller 8 in the third pushing assembly rotates, and the third roller 8 drives the objects to be separated into the lanes into the separation turntable 3.

[0083] When the cache channel and the destination channel are blocked at the same time, the fourth driving member stops driving the third pushing assembly, so that the objects to be separated stay on the third pushing assembly of the carrying plate 2.

[0084] S35, until the cache load flow does not exceed the cache load threshold, or the load flow does not exceed the load threshold, the fourth driving member continues to drive the third pushing assembly to push the objects to be laned into the lane-dividing turntable 3.

[0085] In another specific implementation, when the load flow exceeds a preset load threshold, the dynamic adjustment mechanism can be activated to generate a deceleration control instruction, and the speed of the conveyor belt of the feed channel is reduced according to the deceleration control instruction; when the load flow does not exceed the preset load threshold, an acceleration control instruction is generated, and the speed of the conveyor belt of the feed channel is restored to the speed before the deceleration according to the acceleration control instruction.

[0086] This dynamic adjustment mechanism can ensure that the entire sorting system can maintain efficient and stable operation when faced with emergencies or peak periods, and also fully considers factors such as system load balancing and fault prevention.

[0087] S4, when the lane turntable 3 has completed its rotation, the result of the rotation is verified, which specifically includes the following steps.

[0088] S41, monitoring the actual rotation of the lane turntable 3.

[0089] S42: When the lane turntable 3 rotates according to the control instruction, the actual rotation situation is compared with the control instruction to obtain a first comparison result.

[0090] When there is a difference in the first comparison result, the difference value is calculated, and a difference adjustment instruction is generated according to the difference value, and the lane turntable 3 is secondarily controlled according to the difference adjustment instruction.

[0091] S43, when the lane turntable 3 rotates according to the cache lane instruction, the actual rotation situation is compared with the cache lane instruction to obtain a second comparison result.

[0092] When there is a difference in the second comparison result, the difference value is calculated, and a difference adjustment instruction is generated according to the difference value, and the lane turntable 3 is secondarily controlled according to the difference adjustment instruction.

[0093] The above steps S42 and S43 are arranged in parallel and there is no order relationship.

[0094] S5, driving the first pushing assembly on the lane dividing turntable 3 to push the objects to be laned into the corresponding destination channel 4, specifically including the following steps.

[0095] After the lane dividing turntable 3 rotates, the first roller 6 of the first pushing component first pushes the items to be divided into lanes onto the carrying plate 2. At this time, the items to be divided into lanes fall on the second pushing component corresponding to their own destination channel 4. The second roller 7 of the second pushing component pushes the items to be divided into lanes into the corresponding destination channel 4, thus completing the entire sorting process.

[0096] Specifically, after receiving the information of the objects to be separated from the identification device 5, the control system of this embodiment will first determine the destination channel 4 of the objects based on this information. Then, the system will perform accurate calculations based on the pre-set lane separation parameters, including the center coordinates of the lane separation turntable 3, the coordinates of the center of the entrance of each destination channel 4, etc. Through the above series of complex calculation processes, the control system can generate a highly accurate control instruction, which not only includes the specific angle that the lane separation turntable 3 needs to rotate, but also clarifies the direction of rotation. In this way, when the drive receives this instruction and drives the lane separation turntable 3 to rotate, it can ensure that the objects are accurately pushed to the corresponding destination channel 4.

[0097] The above method not only significantly improves the efficiency and accuracy of logistics sorting, but also brings huge economic benefits and competitive advantages to logistics companies.

[0098] The above description is only an optional embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
