Description

Technical Field

[0001] This application relates to the field of tobacco processing equipment, and in particular to a photoelectric tobacco stem sorting mechanism and sorting device. Background Technology

[0002] In the cigarette production process, the separation of tobacco shreds from stems is a crucial step affecting cigarette quality. Currently, the industry commonly uses methods such as wind sorting and vibrating sieves for stem separation. However, the removal of stems is relatively poor, and even with simple and coarse removal, it is necessary to repeat the process multiple times to obtain finished tobacco shreds.

[0003] The prior art publication CN216827285U provides a vision-guided irregular object identification and sorting mechanism. A vision inspection device is installed on the top of the mounting frame. The vision inspection device includes a camera and a light source, both located above the center of a flipping conveyor. The camera can capture images of the frozen dumplings on the flipping conveyor from all angles, and the light source illuminates the frozen dumplings, making the captured images clearer and more accurate. The images are then transmitted to a dedicated image processing system. Based on pixel distribution, brightness, color, and other information, the image information is converted into digital signals. The image system performs various calculations on these signals to extract the target's features, and then controls the on-site equipment actions based on the judgment results.

[0004] However, when existing sorting mechanisms are applied to the sorting of tobacco shreds and stem sticks, the visual detection device above cannot easily identify the tobacco shreds or stem sticks at the bottom of the stack when the tobacco shreds and stem sticks are stacked, making it difficult to sort the tobacco shreds or stem sticks in the stacked state, resulting in poor accuracy in sorting tobacco shreds and stem sticks. Utility Model Content

[0005] To improve the sorting accuracy of the sorting mechanism, this application provides a photoelectric tobacco stem and shred sorting mechanism and sorting device.

[0006] The photoelectric tobacco stem sorting mechanism provided in this application adopts the following technical solution: A photoelectric tobacco stem sorting mechanism includes a sorting execution mechanism, a moving mechanism, and a vision detection device on a frame. The frame is provided with a sorting station, and the sorting execution mechanism is located at the sorting station so as to be able to move the mixed materials to the sorting station. The sorting execution mechanism performs a sorting action on material A in the mixed materials. The frame is equipped with a first collection device and a second collection device. There are two sets of vision detection devices, which are arranged opposite each other on both sides of the mixture to visually identify material A in the mixture and sort material A to the first collection device through the sorting execution mechanism. The moving mechanism can transport material B to the second collection device.

[0007] By adopting the above technical solution, when the mixed material is transported to the sorting station by the moving mechanism, two sets of vision inspection devices visually identify material A from both sides of the mixed material. The sorting execution mechanism sorts material A to the first collection device, and the second collection device collects the sorted material B. Compared with the prior art, this application adopts a scheme of two sets of vision inspection devices to identify the mixed material, and performs visual identification on both sides of the mixed material, which effectively avoids the phenomenon that material B blocks material A and makes the vision inspection device unable to identify material A, thereby improving the accuracy of sorting material A and material B.

[0008] Preferably, the visual inspection device includes a camera and a lighting lamp. The camera and the lighting lamp are both fixedly connected to the frame and face the mixed material. The camera can identify material A in the mixed material, and the lighting lamp can provide lighting assistance for the camera's imaging.

[0009] By adopting the above technical solution, the camera can clearly identify material A in the mixture with the assistance of lighting, avoiding unclear imaging caused by insufficient light and improving the sorting accuracy of the sorting execution mechanism.

[0010] Preferably, the moving mechanism includes a chute, which is fixedly connected to the frame and inclined along the horizontal direction. The chute is located above the sorting station, and the mixed material can move along the chute to the sorting station under its own gravity. The second collecting device is arranged opposite to the chute and is used to receive material B.

[0011] By adopting the above technical solution, the automatic conveying of mixed materials is achieved by utilizing the inclined chute structure and the self-weight of the mixed materials, so that the sorting process does not require external force and simplifies the process of conveying mixed materials.

[0012] Preferably, the sorting actuator includes air nozzles, and a plurality of air nozzles are arranged along a direction perpendicular to the movement of the mixed material. The air nozzles are fixedly connected to the frame, and each air nozzle is located in the sorting station below the chute and faces the mixed material. The air nozzles are capable of sorting material A to the first collection device.

[0013] By adopting the above technical solution, several air nozzles can instantly spray airflow, causing material A to be quickly blown away and enter the first collection device, thereby improving the sorting efficiency of the sorting execution mechanism.

[0014] This application also provides a photoelectric tobacco stem sorting device using the following technical solution: A photoelectric tobacco stem and shred sorting device, using the aforementioned photoelectric tobacco stem and shred sorting mechanism, includes five sorting mechanisms on the frame. The five sorting mechanisms are arranged sequentially along the flow direction of material A or material B. The downstream sorting mechanism is used to receive material A and material B sorted by the upstream sorting mechanism, so as to be able to sort the sorted material A or material B again.

[0015] By adopting the above technical solution, the sorting mechanism is arranged sequentially along the material flow direction and sorted multiple times, so that the downstream sorting mechanism sorts the material after the upstream sorting again, thereby improving the sorting accuracy of the sorting device.

[0016] Preferably, the five sorting mechanisms are divided into a first sorting mechanism at the upper layer, a second and fourth sorting mechanisms at the middle layer, and a third and fifth sorting mechanisms at the lower layer. The second and fourth sorting mechanisms are used to receive materials A and B from the first sorting mechanism, and the third and fifth sorting mechanisms are used to receive materials A and B from the second sorting mechanism. The five sorting mechanisms are capable of performing step-by-step sorting operations on the mixed materials.

[0017] By adopting the above technical solution, and through the layout of five sorting mechanisms in three layers (upper, middle, and lower), material A and material B in the mixture can be sorted multiple times, thereby improving the sorting accuracy of the sorting device.

[0018] Preferably, the frame is equipped with a vibrating feeder, which is fixedly connected to the frame and located above the first sorting mechanism, and is capable of conveying the mixed material into the moving mechanism of the first sorting mechanism.

[0019] By adopting the above technical solution, the vibrating feeder spreads the mixed material evenly through vibration, enabling the mixed material to be conveyed evenly and continuously, thus improving the sorting accuracy of the sorting device.

[0020] Preferably, the frame is provided with a conveyor belt, which is rotatably connected to the frame and located below at least one of the first collecting device and the second collecting device. The conveyor belt is used to transport material A or material B.

[0021] By adopting the above technical solution, the conveyor belt receives and transports sorted material A or material B, enabling material A or material B to be automatically transported out, thus avoiding the accumulation of material A or material B.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. Compared with the existing technology of using a single vision inspection device to identify materials, this application adopts a scheme of using two sets of vision inspection devices to identify mixed materials, and performs visual identification on both sides of the mixed materials. This effectively avoids the phenomenon that material B blocks material A, making the vision inspection device unable to identify material A, thereby improving the accuracy of sorting tobacco shreds and stems.

[0023] 2. By utilizing the inclined chute structure and the self-weight of the mixed materials, the mixed materials are automatically conveyed, eliminating the need for external force to drive the sorting process and simplifying the conveying process of the mixed materials.

[0024] 3. The layout of five sorting mechanisms in three layers (upper, middle, and lower) enables material A and material B in the mixture to be sorted multiple times, improving the sorting accuracy of the sorting device. Attached Figure Description

[0028] The following is in conjunction with the appendix Figures 1-2 This application will be described in further detail.

[0029] This application discloses a photoelectric tobacco stem sorting mechanism.

[0030] Reference Figure 1 A photoelectric mixed material sorting mechanism and sorting device includes a sorting execution mechanism 2, a moving mechanism 3, and a vision inspection device 4 on a frame 1. A sorting station 5 is provided on the frame 1. The sorting execution mechanism 2 is located at the sorting station 5. Material A is tobacco shreds and material B is stems. The moving mechanism 3 is set on the frame 1 and can move the mixed material to the sorting station 5. The sorting execution mechanism 2 is set on the frame 1 and performs sorting action on the tobacco shreds in the mixed material. The frame 1 is equipped with a first collecting device 11 and a second collecting device 12. The first collecting device 11 is a tobacco tube 111, and the second collecting device 12 is a stem tube 121. The visual inspection device 4 is installed on the frame 1. There are two sets of visual inspection devices 4, which are arranged opposite each other on both sides of the mixture to visually identify the tobacco in the mixture. The tobacco is sorted into the tobacco tube 111 by the sorting execution mechanism 2. The moving mechanism 3 can transport the stem tubes into the stem tube 121, which effectively avoids the phenomenon that the stem tubes block the tobacco and prevents the visual inspection device 4 from identifying the tobacco, thereby improving the accuracy of the visual inspection device 4.

[0031] The moving mechanism 3 includes a chute 31, which is fixedly connected to the frame 1 and inclined along the horizontal direction. The bottom end of the chute 31 is positioned above the sorting station 5, allowing the mixed materials to be conveyed from the bottom end of the chute 31 to the sorting station 5. The skewer tube 121 is positioned opposite to the bottom outlet of the chute 31 and is used to receive the skewer tubes remaining after the mixed materials are sorted, so that the sorting process does not require external force and simplifies the process of conveying the mixed materials.

[0032] The visual inspection device 4 includes an illumination lamp 41 and a CCD camera 42. Both CCD cameras 42 and illumination lamps 41 are fixedly connected to the frame 1 and face the sorting station 5. The frame 1 is equipped with a power supply for the illumination lamps 41. The illumination lamps 41 can assist the CCD camera 42 to make the imaging clearer. The two sets of CCD cameras 42 are a front CCD camera 42 and a rear CCD camera 42. The front CCD camera 42 is located above the sorting station 5 and is used to detect tobacco shreds on top of the mixed materials in the sorting station 5. The rear CCD camera 42 is located below the sorting station 5 and is used to detect tobacco shreds below the mixed materials in the sorting station 5. Both sets of CCD cameras 42 can identify tobacco shreds from the mixed materials in the sorting station 5. With the assistance of the illumination lamps 41, the CCD cameras 42 can clearly identify tobacco shreds in the mixed materials, which improves the sorting accuracy of the sorting execution mechanism 2.

[0033] The sorting execution mechanism 2 includes several air nozzles 21, which are arranged in a row perpendicular to the direction of movement of the mixed materials and are all fixedly connected to the frame 1. Each air nozzle 21 is located below the sorting station 5 and faces the sorting station 5. A pneumatic mechanism 22 is fixedly installed on the frame 1. The pneumatic mechanism 22 includes a solenoid valve 221 and an air pipe 222. The air nozzles 21 are connected to the solenoid valve 221 through the air pipe 222. During the recognition process of the CCD camera 42, the sorting signal is transmitted to the solenoid valve 221. The solenoid valve 221 drives the gas in the air pipe 222 to be ejected from the air nozzles 21, which ejects the tobacco into the tobacco tube 111, so that the tobacco is quickly blown away and enters the tobacco tube 111, thereby improving the sorting efficiency of the air nozzle 21.

[0034] The implementation principle of the photoelectric mixed material sorting mechanism in this application embodiment is as follows: the mixed material on the chute 31 is conveyed to the sorting station 5 under the action of gravity. The CCD cameras 42 arranged on both sides can simultaneously identify the tobacco shreds above and below the stacked mixed material. The air nozzles 21 arranged in a row spray gas under the drive of the solenoid valve 221, spraying the tobacco shreds and sorting them into the tobacco tube 111. The stems fall freely into the stem tube 121, effectively avoiding the phenomenon that the stems block the tobacco shreds and the CCD camera 42 cannot identify the tobacco shreds, thereby improving the accuracy of tobacco and stem sorting.

[0035] This application also discloses a photoelectric mixed material sorting device.

[0036] refer to Figure 1 , Figure 2 A photoelectric mixed material sorting device uses the above-mentioned sorting mechanism, including five sorting mechanisms. The five sorting mechanisms are all connected to the frame 1 and are arranged sequentially along the flow direction of the mixed material. The five sorting mechanisms are: a first sorting mechanism 13 located at the upper layer, a second sorting mechanism 14 located on the right side of the middle layer, a fourth sorting mechanism 16 located on the left side, and a third sorting mechanism 15 located on the right side and a fifth sorting mechanism 17 located on the left side of the lower layer. The second sorting mechanism 14 and the fourth sorting mechanism 16 are used to receive the mixed material in the first sorting mechanism 13, and the third sorting mechanism 15 and the fifth sorting mechanism 17 are used to receive the mixed material in the second sorting mechanism 14. The five sorting mechanisms can perform step-by-step sorting operations on the mixed material, thereby improving the sorting accuracy of the sorting device.

[0037] The sorting device divides the five sorting mechanisms into a first sorting mechanism 13, a second sorting mechanism 14, and a fifth sorting mechanism 17 for sorting tobacco shreds, and a third sorting mechanism 15 and a fourth sorting mechanism 16 for sorting stems. The third sorting mechanism 15 and the fourth sorting mechanism 16 are used to sort tobacco shreds from the stems to improve the tobacco shred recovery rate. The first sorting mechanism 13, the second sorting mechanism 14, and the fifth sorting mechanism 17 can perform continuous sorting and step-by-step purification of tobacco shreds. Through multiple sorting operations, the stems in the tobacco shreds are gradually separated, ensuring the quality of the finished tobacco shreds.

[0038] The vibrating feeder 18 is fixedly mounted on the frame 1 and located above the chute 31 in the first sorting mechanism 13. The outlet of the vibrating feeder 18 is corresponding to the inlet of the chute 31. The vibrating feeder 18 spreads the mixed material evenly by vibration, so that the mixed material can be conveyed evenly and continuously, which improves the sorting accuracy of the sorting device.

[0039] The frame 1 is equipped with a conveying mechanism 19, which includes a conveyor belt 191, a motor 192, and a transmission roller 193. The motor 192 is fixedly connected to the frame 1, and the output shaft of the motor 192 is fixedly connected to the rotating roller. The conveyor belt 191 is rotatably connected to the rotating roller, and both are located below the tobacco tube 111 and stem tube 121 in the third sorting mechanism 15, the fourth sorting mechanism 16, and the fifth sorting mechanism 17, so that the finished tobacco and waste stems can be automatically transported out, avoiding the accumulation of mixed materials.

[0040] The first sorting mechanism 13 is used to separate tobacco shreds from the initial mixture. The initial mixture is conveyed to the sorting station 5 via the chute 31. The CCD camera 42 identifies the tobacco shreds in the initial mixture and transmits the identification result to the solenoid valve 221. The solenoid valve 221 drives the gas in the air pipe 222 to be ejected from the air nozzle 21, ejecting the tobacco shreds into the tobacco shred tube 111 on the right side of the first sorting mechanism 13. The remaining stems fall freely into the stem tube 121 on the left side of the first sorting mechanism 13. The tobacco shreds in the right tobacco shred tube 111 are first-selected tobacco shreds. The second sorting mechanism 14, located in the middle layer, receives the first-selected tobacco shreds from the first sorting mechanism 13. The stems in the left stem tube 121 are first-selected stems. The fourth sorting mechanism 16, located in the middle layer, receives the first-selected stems from the first sorting mechanism 13.

[0041] The second sorting mechanism 14 is used to separate stems from the first-selection tobacco. The first-selection tobacco is conveyed to the sorting station 5 via the chute 31. The CCD camera 42 identifies the stems in the first-selection tobacco and transmits the identification result to the solenoid valve 221. The solenoid valve 221 drives the gas in the air pipe 222 to be ejected from the air nozzle 21, ejecting the stems into the stem tube 121 on the right side of the second sorting mechanism 14. The remaining tobacco falls freely into the tobacco tube 111 on the left side of the second sorting mechanism 14. The stems in the right stem tube 121 are second-selection stems, and the third sorting mechanism 15 located below receives the second-selection stems from the second sorting mechanism 14. The tobacco in the left tobacco tube 111 is second-selection tobacco, and the fifth sorting mechanism 17 located below receives the second-selection tobacco from the second sorting mechanism 14.

[0042] The fourth sorting mechanism 16 is used to separate tobacco shreds from the first stem sorting sticks. The first stem sorting sticks are conveyed to the sorting station 5 via the chute 31. The CCD camera 42 identifies the tobacco shreds in the first stem sorting sticks and transmits the identification result to the solenoid valve 221. The solenoid valve 221 drives the gas in the air pipe 222 to be ejected from the air nozzle 21, ejecting the tobacco shreds into the tobacco shred tube 111 on the left side of the fourth sorting mechanism 16. The remaining stem sticks fall freely into the stem stick tube 121 on the right side of the fourth sorting mechanism 16. The tobacco shreds in the left tobacco shred tube 111 are finished tobacco shreds, and the conveyor belt 191 on the frame 1 receives the finished tobacco shreds in the fourth sorting mechanism 16. The stem sticks in the right stem stick tube 121 are waste stem sticks, and the conveyor belt 191 on the frame 1 receives the waste stem sticks in the fourth sorting mechanism 16.

[0043] The third sorting mechanism 15 is used to separate tobacco shreds from the second-stage stem sorting sticks. The second-stage stem sorting sticks are conveyed to the sorting station 5 via the chute 31. The CCD camera 42 identifies the tobacco shreds in the second-stage stem sorting sticks and transmits the identification result to the solenoid valve 221. The solenoid valve 221 drives the gas in the air pipe 222 to be ejected from the air nozzle 21, ejecting the tobacco shreds into the tobacco shred tube 111 on the right side of the third sorting mechanism 15. The remaining stem sticks fall freely into the stem stick tube 121 on the left side of the third sorting mechanism 15. The tobacco shreds in the right-side tobacco shred tube 111 are finished tobacco shreds, and the conveyor belt 191 on the frame 1 receives the finished tobacco shreds from the third sorting mechanism 15. The stem sticks in the left-side stem stick tube 121 are waste stem sticks, and the conveyor belt 191 on the frame 1 receives the waste stem sticks from the third sorting mechanism 15.

[0044] The fifth sorting mechanism 17 is used to separate stems from the second-sorted tobacco. The second-sorted tobacco is conveyed to the sorting station 5 via the chute 31. The CCD camera 42 identifies the stems in the second-sorted tobacco and transmits the identification result to the solenoid valve 221. The solenoid valve 221 drives the gas in the air pipe 222 to be ejected from the air nozzle 21, ejecting the stems into the stem tube 121 on the left side of the fifth sorting mechanism 17. The remaining tobacco falls freely into the tobacco tube 111 on the right side of the fifth sorting mechanism 17. The stems in the left stem tube 121 are waste stems, and the conveyor belt 191 on the frame 1 receives the waste stems from the fifth sorting mechanism 17. The tobacco in the right tobacco tube 111 is finished tobacco, and the conveyor belt 191 on the frame 1 receives the finished tobacco from the fifth sorting mechanism 17.

[0045] The implementation principle of the photoelectric mixed material sorting device in this application is as follows: The vibrating feeder 18 feeds the initial mixture to the first sorting mechanism 13. The chute 31 transports the mixture to the sorting station 5 of the first sorting mechanism 13. The CCD cameras 42 on both sides identify the tobacco shreds from the mixture. The nozzle 21 sorts out the identified tobacco shreds and sends them into the tobacco tube 111 on the right to form first-selected tobacco shreds. The remaining stem sticks fall freely into the stem stick tube 121 on the left to form first-selected stem sticks.

[0046] The second sorting mechanism 14 receives the first-selection tobacco from the first sorting mechanism 13. The chute 31 transports the first-selection tobacco to the sorting station 5 of the second sorting mechanism 14. The CCD cameras 42 on both sides identify the stems from the first-selection tobacco. The nozzle 21 sorts out the identified stems and sends them into the stem tube 121 on the right to form second-selection stems. The remaining tobacco falls freely into the tobacco tube 111 on the left to form second-selection tobacco.

[0047] The fourth sorting mechanism 16 receives the first stem sticks from the first sorting mechanism 13. The chute 31 transports the first stem sticks to the sorting station 5 of the fourth sorting mechanism 16. The CCD cameras 42 on both sides identify the tobacco shreds from the first stem sticks. Then, the nozzle 21 sorts out the identified tobacco shreds and sends them into the tobacco tube 111 on the left to form finished tobacco shreds. The remaining stem sticks fall freely into the stem stick tube 121 on the right to form waste stem sticks. The finished tobacco shreds and waste stem sticks produced by the fourth sorting mechanism 16 are automatically transported out by the conveyor belt 191.

[0048] The third sorting mechanism 15 receives the second-selection stem tags from the second sorting mechanism 14. The chute 31 transports the second-selection stem tags to the sorting station 5 of the third sorting mechanism 15. The CCD cameras 42 on both sides identify the tobacco shreds from the second-selection stem tags. The nozzle 21 sorts out the identified tobacco shreds and sends them into the tobacco tube 111 on the right to form finished tobacco shreds. The remaining stem tags fall freely into the stem tag tube 121 on the left to form waste stem tags. The finished tobacco shreds and waste stem tags produced by the third sorting mechanism 15 are automatically transported out by the conveyor belt 191.

[0049] The fifth sorting mechanism 17 receives the second-sorted tobacco from the second sorting mechanism 14. The chute 31 transports the second-sorted tobacco to the sorting station 5 of the fifth sorting mechanism 17. The CCD cameras 42 on both sides identify the stems from the second-sorted tobacco. Then, the nozzle 21 sorts out the identified stems and enters the stem tube 121 on the left to form waste stems. The remaining tobacco falls freely into the tobacco tube 111 on the right to form finished tobacco. The finished tobacco and waste stems produced by the fifth sorting mechanism 17 are automatically transported out by the conveyor belt 191. Through the five sorting mechanisms, the tobacco is sorted step by step, resulting in better quality finished tobacco.

[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
