Abstract
Description
Technical Field
[0001] This invention relates to the field of material sorting system technology, and in particular to a material sorting system and control method. Background Technology
[0002] Existing material appearance inspection equipment typically includes a feeding mechanism, a conveying mechanism, an inspection mechanism, and a sorting mechanism. During operation, the material is conveyed to a turntable by the feeding mechanism, and its posture is adjusted by a guiding mechanism during transport, allowing the material to move along a predetermined trajectory to the inspection position. The inspection mechanism then performs appearance inspection on the material and outputs the inspection results. Subsequently, the sorting mechanism conveys the material to the corresponding qualified or unqualified areas based on the inspection results.
[0003] In related technologies, sorting mechanisms typically employ air blowing for sorting, where solenoid valves control the opening and closing of air nozzles to direct materials into different recycling zones. However, the sorting accuracy of this method is easily affected by various factors, such as the response speed of the solenoid valve, fluctuations in air supply pressure, and positional deviations of the material during transport, leading to instability in the sorting process.
[0004] Therefore, in practical applications, the following situations may occur: materials that should be deemed qualified are not accurately conveyed to the qualified area, or materials that should be deemed unqualified are mistakenly conveyed to the qualified area, resulting in sorting errors. These problems will directly affect the quality of the final product and may even lead to unqualified materials being mixed with qualified products, posing a significant quality risk. Summary of the Invention

A sorting device is disposed beside the turntable and downstream of the plurality of detection devices; the sorting device includes a qualified area, an unqualified area and a feeding mechanism; A monitoring device is used to detect whether the material has passed through the target area and generate a corresponding second detection result, wherein the target area is located between the qualified area and the unqualified area; The control module, connected to multiple detection devices and the feeding mechanism, is used to generate a first detection result based on the image information, and control the feeding mechanism to transport the material to the qualified area or the unqualified area based on the first detection result; the control module is also configured to compare the first detection result with the second detection result to determine whether the material is in a normal, missed, or incorrect sorting state.
[0008] Optionally, when the first detection result indicates that the target material is a qualified product, and the second detection result indicates that the target material has passed through the target area, the control module determines that the target material has been missed in sorting. When the first detection result indicates that the target material is a non-conforming product, and the second detection result indicates that the target material has not passed through the target area, the control module determines that the target material has been missorted.
[0009] Optionally, when the first detection result indicates that the target material is a qualified product and the second detection result indicates that the target material has not passed through the target area, the control module determines that the target material is normal; When the first detection result indicates that the target material is a non-conforming product, and the second detection result indicates that the target material passes through the target area, the control module determines that the target material is normal.
[0010] Optionally, the monitoring device includes: A monitoring camera is installed above the sorting device to acquire a second detection result of the material in the target area, either directly or through the first reflector.

[0012] Optionally, the plurality of the detection devices further include: The fourth detection component includes a fourth camera, a fourth light source, and a third reflector. The fourth camera acquires image information of the outer surface of the material through the third reflector. The fifth detection component includes a fifth camera, a fifth light source, and a fourth reflector. The fifth camera acquires image information of the bottom surface of the material through the fourth reflector. The sixth detection component includes a sixth camera, a sixth light source, and a fifth reflector. The sixth camera acquires image information of the rear side of the material through the fifth reflector.
[0013] Optionally, the sorting device includes: A first air blowing mechanism is installed above the turntable and is arranged corresponding to the qualified area; the first air blowing mechanism is used to blow the qualified material into the qualified area; The second air blowing mechanism is installed above the turntable and is arranged corresponding to the defective area; the second air blowing mechanism is used to blow the defective material into the defective area.
[0014] Optionally, it also includes: A guiding mechanism, installed upstream of the plurality of the detection devices, is used to guide the material as it is output from the vibratory feeder to the turntable.
[0015] Specifically, a control method for a material sorting system, applied to the aforementioned material sorting system, includes the following steps: Upon receiving a feeding signal, the vibratory feeder is controlled to convey the material onto the turntable. Multiple detection devices are controlled to perform appearance inspections on different sides of the material and generate image information. A first detection result is generated based on the image information, and the material feeding mechanism of the sorting device is controlled to send the material to the qualified area or the unqualified area based on the first detection result; and the monitoring device is controlled to detect whether the material has passed through the target area and generate a corresponding second detection result. The first detection result is compared with the second detection result to determine whether the material is in a normal, missed, or incorrect sorting state.
[0016] Optionally, the step of comparing the first detection result with the second detection result to determine whether there is any material missorting specifically includes the following steps: When the first detection result indicates that the target material is a qualified product, and the second detection result indicates that the target material was missed when it passed through the target area; or When the first detection result indicates that the target material is a non-conforming product, and the second detection result indicates that the target material has not passed through the target area, the target material is determined to have been missorted; or The target material is deemed normal when the first test result indicates that the target material is a qualified product, and the second test result indicates that the target material has not passed through the target area; or The first test result indicates that the target material is a non-conforming product, and the second test result indicates that the target material is normal when it passes through the target area.
[0017] In this invention, multiple detection devices are used to perform appearance inspection on different sides of the material as it rotates with the turntable, and generate image information. A sorting device is located downstream of these detection devices. A monitoring device is used to detect whether the material has passed through the target area and generates a corresponding second detection result.

This technical solution, by setting up a monitoring device at the sorting device and comparing the first and second detection results, achieves online verification of the material sorting results. Compared to methods that rely solely on detection results for direct sorting, this embodiment can reconfirm the actual flow direction of the material after sorting, thereby promptly identifying missed or incorrect sorting situations, significantly improving sorting accuracy, reducing the risk of unqualified materials mixing into the qualified area, and improving the reliability of the overall detection system and the stability of product quality.

[0026] Figure 1 This is a schematic top view of a material sorting system 100 according to an embodiment of the present invention. Figure 2 This is a schematic partial view of a detection device according to an embodiment of the present invention. Figure 3 This is a schematic structural diagram of a material sorting system 100 according to an embodiment of the present invention, taken from one angle. Figure 4 This is another schematic partial view of a detection device according to an embodiment of the present invention. Figure 5 This is a schematic structural diagram of a sorting device 40 according to an embodiment of the present invention. Figures 1 to 5As shown, in a specific embodiment, the material sorting system 100 includes a turntable 10, a vibrating plate 20, multiple detection devices, a sorting device 40, a monitoring device 50, and a control module. The turntable 10 is rotatable, and the vibrating plate 20 is disposed beside the turntable 10 for conveying materials onto the turntable 10. Multiple detection devices are arranged circumferentially along the turntable 10 to perform appearance inspections on different sides of the material as it rotates with the turntable 10, generating image information. The sorting device 40 is disposed beside the turntable 10 and downstream of the multiple detection devices. The sorting device 40 includes a qualified area 43, a non-qualified area 44, and a feeding mechanism. The monitoring device 50 detects whether the material has passed through a target area and generates a corresponding second detection result; the target area is located between the qualified area 43 and the non-qualified area 44. The control module is connected to the multiple detection devices and the feeding mechanism, and generates a first detection result based on the image information, and controls the feeding mechanism to convey the material to the qualified area 43 or the non-qualified area 44 based on the first detection result. The control module is also configured to compare the first detection result with the second detection result to determine whether the material is in a normal, missed, or incorrect sorting state.
[0027] This embodiment achieves online verification of material sorting results by installing a monitoring device 50 at the sorting device 40 and comparing the first and second detection results. Compared to methods that rely solely on detection results for direct sorting, this embodiment can reconfirm the actual flow of materials after sorting, thereby promptly identifying missed or incorrect sorting, significantly improving sorting accuracy, reducing the risk of unqualified materials mixing into the qualified area 43, and enhancing the reliability of the overall detection system and the stability of product quality.
[0028] In some embodiments, when the first detection result indicates that the target material is a qualified product and the second detection result indicates that the target material has passed through the target area, the control module determines that the target material has been missed in sorting. When the first detection result indicates that the target material is a non-qualified product and the second detection result indicates that the target material has not passed through the target area, the control module determines that the target material has been missorted. Here, if the target material is a qualified product, it should be conveyed to the qualified area 43 by the sorting device 40 and should not appear in the downstream target area. If the target material is a non-qualified product, it should be conveyed to the non-qualified area 44 after passing through the target area, but the target material does not appear in the target area, indicating that it has been missorted into the qualified area 43.
[0029] This embodiment achieves accurate differentiation between "missed sorting" and "incorrect sorting" by combining the first detection result with the status of whether the material has passed through the target area. Specifically, it uses the actual path information of the material to perform reverse verification of the sorting execution result, enabling the system to determine whether the sorting execution result is correct, thereby improving the system's diagnostic and anomaly identification capabilities.
[0030] In some embodiments, when the first detection result indicates that the target material is a qualified product and the second detection result indicates that the target material has not passed through the target area, the control module determines that the target material is normal. When the first detection result indicates that the target material is a non-qualified product and the second detection result indicates that the target material has passed through the target area, the control module determines that the target material is normal.
[0031] This embodiment further supplements the normal state determination logic to construct a complete sorting state determination system, enabling the control module to perform closed-loop judgment on all possible situations, avoiding state omissions or judgment ambiguities, thereby improving the stability of system operation and the completeness of judgment results.
[0032] In some embodiments, the control module will issue an alarm when it determines that materials are missed or missorted, thereby providing real-time alarm for mixed materials and preventing defective products from flowing out.
[0033] In some embodiments, the turntable 10 is made of glass. In another embodiment, the material of the turntable 10 may also be selected according to specific design requirements.
[0034] In some embodiments, the monitoring device 50 includes a monitoring camera 51 and a monitoring light source 53. The monitoring camera 51 is mounted above the sorting device 40 and is used to acquire the second detection result of the material in the target area directly or through the first reflector 52. The monitoring light source 53 is disposed at a corresponding position in the target area and is configured in conjunction with the monitoring camera 51. Here, the monitoring camera 51 is a high-speed camera.
[0035] Figure 6 This is a schematic structural diagram of a monitoring device 50 according to an embodiment of the present invention. Figure 6 As shown, in one embodiment, the monitoring camera 51 directly acquires the second detection result of the material in the target area. The monitoring light source 53 is installed below the turntable 10, and the monitoring camera 51 is vertically arranged, directly facing the turntable 10, and corresponding to the monitoring light source 53. Here, the monitoring light source 53 can be understood as a backlight.
[0036] Figure 7 This is a schematic structural diagram of a monitoring device 50 according to another embodiment of the present invention. Figure 7 As shown, in another embodiment, the monitoring camera 51 directly acquires the second detection result of the material in the target area. The monitoring light source 53 is mounted above the turntable 10, and the monitoring camera 51 is vertically arranged and corresponds to the monitoring light source 53. Here, the monitoring light source 53 can be understood as a front light source.
[0037] Figure 8 This is a schematic structural diagram of a monitoring device 50 according to yet another embodiment of the present invention. Figure 8As shown, in another embodiment, the monitoring camera 51 acquires a second detection result of the material in the target area via the first reflector 52. The monitoring light source 53 is mounted below the turntable 10, and the first reflector 52 is mounted above the turntable 10, corresponding to the monitoring light source 53. The monitoring camera 51 is horizontally positioned and aligned with the first reflector 52, thereby detecting whether the material has passed through the target area via the first reflector 52. Here, the monitoring light source 53 can be understood as a backlight.
[0038] Figure 9 This is a schematic structural diagram of a monitoring device 50 according to another embodiment of the present invention. Figure 9 As shown, in another embodiment, the monitoring camera 51 acquires a second detection result of the material in the target area via the first reflector 52. The monitoring light source 53 is mounted above the turntable 10, and the first reflector 52 is mounted above and corresponding to the monitoring light source 53. The monitoring camera 51 is horizontally positioned and aligned with the first reflector 52, thereby detecting whether the material has passed through the target area via the first reflector 52. Here, the monitoring light source 53 can be understood as a front light source.
[0039] In other words, the monitoring device 50 of the present invention has multiple design methods and installation methods, which can be selected according to specific design requirements.
[0040] This embodiment, through the cooperative structure of the monitoring camera 51 and the monitoring light source 53, enables the monitoring device 50 to stably acquire the passage status information of materials within the target area. Furthermore, by combining it with the first reflector 52 structure, effective coverage of key areas can be achieved within a limited installation space, improving detection flexibility and spatial adaptability, while ensuring the stability and accuracy of the detection signal.
[0041] In some embodiments, the plurality of detection devices include a first detection component 61, a second detection component 62, and a third detection component 63. The first detection component 61 includes a first camera 611 and a first light source 612, used to acquire image information of the front face of the material. The second detection component 62 includes a second camera 621 and a second light source 622, used to acquire image information of the top face of the material. The third detection component 63 includes a third camera 632, a third light source 631, and a second reflector 633, wherein the third camera 632 acquires image information of the inner face of the material through the second reflector 633.
[0042] In some embodiments, the plurality of detection devices further include a fourth detection component 64, a fifth detection component 65, and a sixth detection component 66. The fourth detection component 64 includes a fourth camera 641, a fourth light source 642, and a third reflector 643. The fourth camera 641 acquires image information of the outer surface of the material through the third reflector 643. The fifth detection component 65 includes a fifth camera 651, a fifth light source 652, and a fourth reflector 653. The fifth camera 651 acquires image information of the bottom surface of the material through the fourth reflector 653. The sixth detection component 66 includes a sixth camera 661, a sixth light source 662, and a fifth reflector 663. The sixth camera 661 acquires image information of the rear surface of the material through the fifth reflector 663.
[0043] This embodiment uses multiple detection components to acquire images of different sides of the material, preferably achieving omnidirectional appearance inspection of all six sides. This allows the system to acquire complete appearance information, significantly improving the detection coverage and identification accuracy of surface defects and reducing missed detections. Furthermore, by combining six-sided inspection with a subsequent sorting result verification mechanism, the accuracy and reliability of the overall sorting results can be improved while ensuring comprehensive inspection.
[0044] In some embodiments, the sorting device 40 includes a first air blowing mechanism 41 and a second air blowing mechanism 42. The first air blowing mechanism 41 is mounted above the turntable 10 and is arranged corresponding to the qualified area 43. The first air blowing mechanism 41 is used to blow qualified materials into the qualified area 43. The second air blowing mechanism 42 is mounted above the turntable 10 and is arranged corresponding to the unqualified area 44. The second air blowing mechanism 42 is used to blow unqualified materials into the unqualified area 44.
[0045] This embodiment achieves rapid sorting based on detection results by setting air blowing mechanisms corresponding to different sorting areas. It features a simple structure and fast response speed, meeting the requirements of high-speed continuous sorting. Furthermore, when used in conjunction with the monitoring device 50, the air blowing sorting results can be effectively verified, thereby compensating for the instability issues inherent in pneumatic actuation.
[0046] In some embodiments, both the qualified area 43 and the unqualified area 44 adopt a box structure, meaning that the blowing mechanism blows qualified and unqualified products into their respective boxes. In some embodiments, unqualified products correspond to two boxes respectively, and can be discharged separately according to the unqualified status, with each box corresponding to one blowing mechanism.
[0047] In some embodiments, the material sorting system 100 further includes a guiding mechanism 30, which is installed upstream of a plurality of detection devices for guiding the material as it is output from the vibratory feeder 20 to the turntable 10.
[0048] This embodiment uses a guiding mechanism 30 to adjust the posture of the material before it enters the turntable 10, so that the material can be stably conveyed along a predetermined trajectory, thereby improving the stability and consistency of the subsequent detection and sorting process and reducing detection errors or sorting deviations caused by posture deviations.
[0049] Figure 10 This is a schematic flowchart of a control method for a material sorting system 100 according to an embodiment of the present invention. Figure 10 As shown, in a specific embodiment, the control method for the material sorting system 100 is applied to the material sorting system 100 of any of the above embodiments, and the control method includes the following steps: Step S100: Upon receiving the feeding signal, control the vibratory feeder 20 to convey the material onto the turntable 10; Step S200: Control multiple detection devices to perform appearance inspection on different sides of the material and generate image information; In step S300, a first detection result is generated based on the image information, and the material feeding mechanism of the sorting device 40 is controlled to send the material to the qualified area 43 or the unqualified area 44 based on the first detection result; and the monitoring device 50 is controlled to detect whether the material has passed through the target area and generate the corresponding second detection result. Step S400: Compare the first detection result with the second detection result to determine whether the material is in a normal, missed, or incorrect sorting state.
[0050] This embodiment introduces a path detection-based sorting result verification step into the control method, enabling the system to perform a secondary confirmation of the sorting results after completing detection and sorting, thereby forming a closed-loop control process of "detection-sorting-verification", which effectively improves sorting accuracy and system reliability.
[0051] In some embodiments, step S400 specifically includes the following steps: Step S410: If the first detection result indicates that the target material is a qualified product, and the second detection result indicates that the target material was missed when it passed through the target area; or Step S420: If the first detection result indicates that the target material is a non-conforming product, and the second detection result indicates that the target material has not passed through the target area, the target material is determined to have been missorted; or Step S430: If the first test result indicates that the target material is a qualified product, and the second test result indicates that the target material has not passed through the target area, the target material is determined to be normal; or In step S440, the first detection result indicates that the target material is a non-conforming product, and the second detection result indicates that the target material is normal when passing through the target area. It should be noted that there is no sequential relationship between steps S410, S420, S430, and S440.
[0052] This embodiment constructs a combined judgment logic based on the first and second detection results to achieve a refined classification of material sorting status, enabling the system to accurately identify missed sorting, incorrect sorting, and normal status, thereby providing a reliable basis for subsequent alarms, rejection, or data statistics and improving the system's intelligence level.
[0053] Therefore, those skilled in the art should recognize that although numerous exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention. Thus, the scope of the present invention should be understood and construed as covering all such other variations or modifications.

A first detection result is generated based on the image information, and the material feeding mechanism of the sorting device is controlled to send the material to the qualified area or the unqualified area based on the first detection result; The monitoring device is controlled to detect whether the material has passed through the target area and to generate a corresponding second detection result. The first detection result is compared with the second detection result to determine whether the material is in a normal, missed, or incorrect sorting state.
10. The control method according to claim 9, characterized in that, The step of comparing the first detection result with the second detection result to determine whether there is any material missorting includes the following steps: When the first detection result indicates that the target material is a qualified product, and the second detection result indicates that the target material was missed when it passed through the target area; or When the first detection result indicates that the target material is a non-conforming product, and the second detection result indicates that the target material has not passed through the target area, the target material is determined to be missorted. or The target material is deemed normal when the first test result indicates that the target material is a qualified product and the second test result indicates that the target material has not passed through the target area; or The first test result indicates that the target material is a non-conforming product, and the second test result indicates that the target material is normal when it passes through the target area.
