Description

Technical Field

[0001] This utility model relates to the field of tobacco processing equipment technology, and in particular to a device for detecting the quality compliance of cigarette packs. Background Technology

[0002] Unpacking the raw materials is the first step in cigarette production. Whether the actual quality of the cigarette packs before opening matches the quality indicated on the label has a crucial impact on the quality control of subsequent production processes. The raw materials used in production are supplied by tobacco re-drying plants. After undergoing processing, packing, transportation, storage, and multiple transfers at the re-drying plant, various factors such as deviations in the accuracy of measuring equipment, leakage due to box damage, secondary packaging operations, and changes in the moisture content of the raw materials often result in a difference between the actual quality of the raw materials used in production and the quality indicated on the label. This deviation directly affects the stability of the cigarette production formula, thus adversely impacting the product processing quality and causing changes in the output-to-input ratio.

[0003] To verify the compliance of the quality labeling of cigarette pack raw materials, companies typically need to conduct regular process consumption tests to promptly identify whether the incoming material quality meets the standards. The number of cigarette packs in each batch of production varies depending on the brand and formula, generally ranging from twenty to fifty packs. Currently, most companies still use traditional manual methods: the logistics production workshop extracts cigarette packs batch by batch from the raw material warehouse, uses a trolley to pick them up and weigh them, and manually records the year, grade, carton number, and quality information of each pack on a paper document. After weighing, the cigarette packs must be manually returned to the warehouse one by one, and packs with abnormal quality must be re-verified. This process relies entirely on offline manual operation, is cumbersome and time-consuming, and is no longer suitable for the modern requirements of lean management and intelligent production. Utility Model Content

[0004] The purpose of this invention is to provide a cigarette pack quality conformity testing device to solve the problems of cumbersome, inefficient, and error-prone cigarette pack quality inspection process caused by reliance on manual offline operation in the prior art. It realizes the automation and continuity of cigarette pack quality testing, improves testing efficiency and accuracy, ensures the stability of production formula and product quality, and meets the needs of lean and intelligent production.

[0013] The controller is communicatively connected to the first weighing component, the scanning component, the lifting and transferring mechanism, and the second weighing component.

[0014] As an optional solution for the cigarette pack quality conformity testing device, the first conveying mechanism includes a first frame, a first drive assembly, and a plurality of first rollers.

[0015] As an optional solution for the cigarette pack quality conformity testing device, the lifting and transferring mechanism includes a lifting component and a transferring component. The fixed end of the lifting component is fixedly connected to the first frame, and its output end is connected to the transferring component to drive the transferring component to reciprocate along a third direction, which is perpendicular to the first direction and the second direction.

[0016] As an optional solution for the cigarette pack quality conformity testing device, the transfer assembly includes a connector, a drive motor, a rotating shaft, and multiple conveyor belt groups. The connector is fixedly connected to the output end of the lifting assembly.

[0017] As an optional solution for the cigarette pack quality conformity testing device, the first conveying mechanism also includes a first limiting plate, which is fixedly connected to the first frame and located at one end of the plurality of first rollers away from the third conveying mechanism, for limiting the displacement of the cigarette pack along the second direction.

[0018] As an optional solution for the cigarette pack quality conformity testing device, the scanning component includes a frame and a scanner. The frame spans above the second conveying mechanism, and the scanner is mounted on the frame with its scanning end facing the conveying surface of the second conveying mechanism.

[0019] As an optional solution for the cigarette pack quality compliance testing device, the scanning assembly also includes an audible and visual alarm, which is mounted on the frame and communicates with the controller.

This significantly improves the efficiency and accuracy of cigarette pack quality conformity testing while reducing manual intervention. The overall layout is reasonable, the operation is stable and reliable, and it is easily integrated into existing tobacco production lines. Attached Figure Description

[0041] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0042] This embodiment provides a device for detecting the quality conformity of cigarette packs, such as... Figures 1-6 As shown, the cigarette pack quality conformity testing device includes a first conveying mechanism 1, two second conveying mechanisms 2, a third conveying mechanism 3, a first weighing element 4, a scanning component 5, a lifting and transferring mechanism 6, a second weighing element 7, and a controller (not shown). The two second conveying mechanisms 2 are located at the input and output ends of the first conveying mechanism 1, respectively. The two second conveying mechanisms 2 and the first conveying mechanism 1 are used to convey cigarette packs 100 along a first direction. The third conveying mechanism 3 is connected to the side of the first conveying mechanism 1 and is used to convey cigarette packs 100 along a second direction. The first direction is perpendicular to the second direction. The first weighing element 4 is located below the first conveying mechanism 1. The first weighing component 4 is used to weigh the first actual mass of the cigarette pack 100 located on the first conveying mechanism 1; the scanning component 5 is disposed above the first conveying mechanism 1 and is used to identify the label information on the cigarette pack 100 and obtain the labeled mass of the cigarette pack 100; the lifting and transferring mechanism 6 is disposed on the first conveying mechanism 1 and is used to transfer the cigarette pack 100 from the first conveying mechanism 1 to the third conveying mechanism 3; the second weighing component 7 is disposed below the third conveying mechanism 3 and is used to weigh the second actual mass of the cigarette pack 100 transferred to the third conveying mechanism 3; the controller is communicatively connected to the first weighing component 4, the scanning component 5, the lifting and transferring mechanism 6, and the second weighing component 7.

[0043] The cigarette pack quality conformity inspection device sequentially conveys cigarette packs 100 to the first conveyor mechanism 1 via the second conveyor mechanism 2. The first weighing device 4 performs an initial weighing of the cigarette packs 100 to determine the initial actual weight. Simultaneously, the scanning component 5 automatically identifies the label information on the cigarette packs 100 to obtain the labeled weight. The controller compares the initial actual weight with the labeled weight to determine if the quality of the cigarette packs 100 meets expectations. For cigarette packs 100 requiring weight adjustments, the lifting and transfer mechanism 6 transfers them to the third conveyor mechanism 3, where the second weighing device 7 weighs the cigarette packs 100 again after the weight adjustment to determine the second actual weight, thus confirming the operation results. The entire operation is continuous and automated, achieving close integration and unified control of cigarette pack 100 conveying, quality inspection, information identification, and sorting operations. This significantly improves the efficiency and accuracy of cigarette pack 100 quality conformity inspection while reducing manual intervention. The overall layout is reasonable, the operation is stable and reliable, and it is easy to integrate into existing tobacco production lines.

[0044] In this embodiment, the controller is a PLC or industrial computer used to receive the mass data (first actual mass, second actual mass) of the first weighing device 4 and the second weighing device 7, the tag information (labeled mass) identified by the scanning component 5, and to control the coordinated operation of the first conveying mechanism 1, the second conveying mechanism 2, the third conveying mechanism 3, and the lifting and transferring mechanism 6. In this embodiment, both the first weighing device 4 and the second weighing device 7 are electronic scales.

[0045] like Figures 1-4 As shown, the first conveying mechanism 1 includes a first frame 11, a first drive assembly 12, and multiple first rollers 13. The multiple first rollers 13 are spaced apart along a first direction, with both ends rotatably connected to the first frame 11. The first drive assembly 12 is fixed to the first frame 11, and its output end can drive the multiple first rollers 13 to rotate. Driven by the first drive assembly 12, the multiple first rollers 13 rotate synchronously, enabling the cigarette pack 100 to obtain stable and continuous conveying power in the first direction. This structural design effectively avoids slippage, jamming, or deviation during the conveying process, providing a stable foundation for the subsequent accurate quality inspection of the first weighing component 4 and reliable information identification by the scanning assembly 5, thereby ensuring the smooth, efficient, and reliable operation of the entire quality compliance inspection process.

[0046] like Figure 4As shown, the first drive assembly 12 includes a first motor 121, a first chain drive group 122, and multiple second chain drive groups 123. The first motor 121 is fixedly mounted on the first frame 11. The first chain drive group 122 includes a first driving sprocket, a first chain, and a first driven sprocket. The first driving sprocket is mounted on the output shaft of the first motor 121. Each second chain drive group 123 includes a second driving sprocket, a second driven sprocket, and a second chain. The second driving sprocket and the first driven sprocket are coaxially and fixedly connected. The second driven sprocket is mounted on the end of a first roller 13. The second chain is engaged with the second driving sprocket and the second driven sprocket. The first chain is engaged with the first driving sprocket and the first driven sprocket. The first motor 121 drives the first driving sprocket to rotate, which in turn drives the first driven sprocket and its coaxial second driving sprocket to rotate synchronously. This, in turn, drives the corresponding second driven sprocket through each second chain, ultimately driving all the first rollers 13 to rotate synchronously, thus achieving stable and efficient conveying of the cigarette pack 100.

[0047] like Figure 1 As shown, the second conveying mechanism 2 includes a second frame 21, a second drive assembly, and multiple second rollers 22. The multiple second rollers 22 are spaced apart along a first direction, and both ends are rotatably connected to the second frame 21. The second drive assembly is fixed to the second frame 21, and its output end can drive the multiple second rollers 22 to rotate. Under the drive of the second drive assembly, all the second rollers 22 rotate synchronously. This structure provides a smooth and undisturbed conveying process for the cigarette pack 100, effectively preventing slippage, vibration, or deviation of the cigarette pack 100 during conveying, and providing a stable and reliable transmission guarantee for subsequent high-quality testing operations.

[0048] Furthermore, the second drive assembly includes a second motor, a third chain drive group, and multiple fourth chain drive groups. The second motor is fixedly mounted on the second frame 21. The third chain drive group includes a third driving sprocket, a third chain, and a third driven sprocket. The third driving sprocket is mounted on the output shaft of the second motor. Each fourth chain drive group includes a fourth driving sprocket, a fourth driven sprocket, and a fourth chain. The fourth driving sprocket and the third driven sprocket are coaxially and fixedly connected. The fourth driven sprocket is mounted on the end of a second roller 22. The fourth chain is engaged with the fourth driving sprocket and the fourth driven sprocket. The third chain is also engaged with the third driving sprocket and the third driven sprocket. The second motor drives the third driving sprocket to rotate, which in turn drives the third driven sprocket and its coaxial fourth driving sprocket to rotate synchronously. This, in turn, drives the corresponding fourth driven sprocket through each fourth chain, ultimately driving all the second rollers 22 to rotate synchronously, thus achieving stable and efficient conveying of the cigarette pack 100 on the second conveying mechanism 2.

[0049] like Figure 1 and Figure 2As shown, the third conveying mechanism 3 includes a third frame 31, a second drive assembly, and multiple third rollers 32. The multiple third rollers 32 are spaced apart along the second direction, and both ends of each roller are rotatably connected to the third frame 31. The third drive assembly is fixed to the third frame 31, and its output end can drive the multiple third rollers 32 to rotate. Under the drive of the third drive assembly, all the third rollers 32 rotate synchronously. This structure provides a transfer and conveying channel for the first cigarette packs 100 that do not meet the actual quality requirements, enabling them to be transferred smoothly and reliably to the designated operating position. This facilitates quality adjustment or manual intervention, effectively avoiding process interruptions caused by the backlog of unqualified cigarette packs 100 on the main line or untimely processing, ensuring the smoothness of the overall production rhythm and the convenience of subsequent operations.

[0050] Furthermore, the third drive assembly includes a third motor, a fifth chain drive group, and multiple sixth chain drive groups. The third motor is fixedly mounted on the third frame 31. The fifth chain drive group includes a fifth driving sprocket, a fifth chain, and a fifth driven sprocket. The fifth driving sprocket is mounted on the output shaft of the third motor. Each sixth chain drive group includes a sixth driving sprocket, a sixth driven sprocket, and a sixth chain. The sixth driving sprocket and the fifth driven sprocket are coaxially and fixedly connected. The sixth driven sprocket is mounted on the end of a third roller 32. The sixth chain is engaged with the sixth driving sprocket and the sixth driven sprocket. The fifth chain is also engaged with the fifth driving sprocket and the fifth driven sprocket. The fifth driving sprocket is driven to rotate by the third motor, which in turn drives the fifth driven sprocket and its coaxial sixth driving sprocket to rotate synchronously via the fifth chain. This drives the corresponding sixth driven sprocket via each sixth chain, ultimately driving all the third rollers 32 to rotate synchronously, thus achieving smooth and efficient transfer of unqualified (quality-unacceptable) cigarette packs 100 on the third conveying mechanism 3.

[0051] like Figures 1-6 As shown, the lifting and transferring mechanism 6 includes a lifting component 61 and a transferring component 62. The fixed end of the lifting component 61 is fixedly connected to the first frame 11, and its output end is connected to the transferring component 62, used to drive the transferring component 62 to reciprocate along a third direction, which is perpendicular to the first and second directions. This realizes the automated vertical transfer of cigarette packs 100 between the second conveying mechanism 2 and the third conveying mechanism 3, accurately transferring defective cigarette packs 100 from the inspection station (second conveying mechanism 2) to the processing station (third conveying mechanism 3), effectively avoiding the inefficiency and operational errors caused by manual handling, ensuring the smooth and automated connection of the defective cigarette pack 100 processing flow, and improving the continuity and processing efficiency of the overall production line. In this embodiment, the third direction is defined as the vertical direction, and the first and second directions are defined as two vertical directions in the horizontal plane.

[0052] like Figures 4-6As shown, the lifting assembly 61 includes a bracket 611 and multiple lifting cylinders 612. The bracket 611 is fixedly connected to the first frame 11, and the cylinder bodies of the multiple lifting cylinders 612 are fixedly installed on the bracket 611. The output end of their piston rods is connected to the transfer assembly 62. Through the synchronous extension and retraction of the multiple lifting cylinders 612, the transfer assembly 62 is driven to move stably and synchronously in a third direction, thereby realizing the automated vertical transfer of the cigarette pack 100 between the second conveying mechanism 2 and the third conveying mechanism 3.

[0053] like Figure 5 As shown, the transfer assembly 62 includes a connector 621, a drive motor 622, a rotating shaft 623, and multiple conveyor belt groups 624. The connector 621 is fixedly connected to the output end of the lifting assembly 61. The drive motor 622 is connected to the multiple conveyor belt groups 624 via the rotating shaft 623 to drive the conveyor belt groups 624 to rotate, so that the multiple conveyor belt groups 624 transport the cigarette packs 100 to the third conveying mechanism 3 along the second direction. After the lifting assembly 61 lifts the cigarette packs 100, it immediately provides stable and continuous conveying power along the second direction, realizing the automated lateral transfer of the cigarette packs 100 from the second conveying mechanism 2 to the third conveying mechanism 3. This effectively avoids the problems of damage, positional deviation, or low efficiency of the cigarette packs 100 that may be caused by manual operation, ensuring that the unqualified cigarette packs 100 quickly and accurately leave the main inspection line and enter the processing flow, thus ensuring the continuity and efficiency of the overall production rhythm.

[0054] like Figure 6 As shown, the conveyor belt assembly 624 includes a drive pulley 6241, a driven pulley 6242, a belt 6243, and a tension pulley 6244. The drive pulley 6241 is fixedly connected to the rotating shaft 623. The driven pulley 6242 is supported on the connecting member 621 by bearings. The belt 6243 is wrapped around the drive pulley 6241 and the driven pulley 6242. The tension pulley 6244 is installed on the connecting member 621 and contacts the belt 6243 to adjust the tension of the belt 6243. The drive motor 622 drives the rotating shaft 623 and the drive pulley 6241 to rotate, which in turn drives the driven pulley 6242 to rotate synchronously through the belt 6243, ultimately achieving stable and continuous operation of the belt 6243 in the second direction, providing efficient and slip-free conveying power for the cigarette pack 100.

[0055] Specifically, such as Figure 2As shown, the height of the third roller 32 along the third direction is higher than that of the first roller 13. Multiple conveyor belt groups 624 are respectively located between two adjacent first rollers 13. When the lifting assembly 61 drives the transfer assembly 62 to rise along the third direction, the upper surface of the belt 6243 is flush with the upper surface of the third roller 32, so that the cigarette pack 100 can smoothly transition to the third conveying mechanism 3; when the lifting assembly 61 drives the transfer assembly 62 to descend along the third direction, the upper surface of the belt 6243 is lower than the upper surface of the first roller 13, thereby avoiding interference with the normal conveying of the cigarette pack 100 on the second conveying mechanism 2.

[0056] like Figures 1-4 As shown, the first conveying mechanism 1 also includes a first limiting plate 14, which is fixedly connected to the first frame 11 and located at one end of the plurality of first rollers 13 opposite to the third conveying mechanism 3. The first limiting plate 14 is used to limit the displacement of the cigarette pack 100 along the second direction. The first limiting plate 14 can limit the displacement of the cigarette pack 100 along the second direction during conveying, effectively preventing the cigarette pack 100 from shifting laterally or falling, and ensuring that the cigarette pack 100 is conveyed neatly and stably along the first direction.

[0057] like Figure 1 As shown, the second conveying mechanism 2 also includes two second limiting plates 23, both of which are fixedly connected to the second frame 21 and located at both ends of the plurality of second rollers 22, respectively, to limit the displacement of the cigarette pack 100 along the second direction. The second limiting plates 23 can effectively prevent the cigarette pack 100 from shifting laterally or slipping during the conveying process, ensuring that the cigarette pack 100 is always stably and centrally conveyed along the first direction, providing stable positional conditions for the accurate weighing of the first weighing component 4 and the reliable identification of the scanning component 5, and ensuring the accuracy and consistency of the detection data.

[0058] like Figure 1 and Figure 2 As shown, the third conveying mechanism 3 also includes two third limiting plates 33, both of which are fixedly connected to the third frame 31 and located at both ends of the multiple third rollers 32, respectively, to limit the displacement of the cigarette pack 100 along the first direction. The third limiting plates 33 can prevent the cigarette pack 100 from shifting forward or backward or shifting position during the transverse transfer process, ensuring that the cigarette pack 100 is transported smoothly and directionally along the second direction, providing reliable positional assurance for subsequent quality adjustment, and improving the efficiency and orderliness of handling unqualified cigarette packs 100.

[0059] Specifically, the first limiting plate 14, the second limiting plate 23, and the third limiting plate 33 are all L-shaped plates. One side is fixedly connected to the corresponding frame, and the other side extends perpendicular to the conveying path of the cigarette pack 100 to limit the displacement of the cigarette pack 100. This structure achieves stable installation while forming an effective limiting surface with a small structural space occupation, ensuring the reliability of the limiting and avoiding interference with the conveying of the cigarette pack 100, thus balancing the structural compactness and functional effectiveness of the equipment.

[0060] like Figure 1 , Figure 2 and Figure 4 As shown, the scanning component 5 includes a frame 51 and a scanner 52. The frame 51 is positioned above the second conveying mechanism 2, and the scanner 52 is mounted on the frame 51 with its scanning end facing the conveying surface of the second conveying mechanism 2. This arrangement allows the scanner 52 to face the upper surface of the cigarette pack 100 directly, accurately capturing label information and avoiding recognition errors caused by oblique viewing or obstruction. This provides a reliable guarantee for the controller to obtain accurate label quality data, thereby ensuring the accuracy and reliability of subsequent quality compliance judgments.

[0061] like Figure 1 , Figure 2 and Figure 4 As shown, the scanning component 5 also includes an audible and visual alarm 53, which is mounted on the frame 51 and communicates with the controller. When the controller determines that the actual quality of the cigarette pack 100 does not match the labeled quality, it can immediately drive the audible and visual alarm 53 to emit an audible and visual signal, providing real-time alerts to the operator that there is a quality abnormality. This facilitates rapid manual intervention or handling, effectively preventing substandard cigarette packs 100 from flowing into subsequent stages and improving the response speed and abnormality handling efficiency of the quality inspection process.

[0062] like Figures 1-4 As shown, the first conveying mechanism 1 also includes a first switch 15, which is communicatively connected to the controller and used to control the start and stop of the first conveying mechanism 1. The controller can remotely or automatically control the operating status of the first conveying mechanism 1, realizing flexible scheduling and timely interruption of the conveying process. This facilitates rapid stopping of feeding when an abnormality is detected or adjustments are needed, preventing the continuous entry of problematic cigarette packs 100, and ensuring the orderliness of subsequent weighing and inspection processes and the controllability of the overall system.

[0063] like Figure 1As shown, the second conveying mechanism 2 also includes a second switch 24, which is communicatively connected to the controller and used to control the start and stop of the second conveying mechanism 2. The controller can remotely or automatically control the operating status of the second conveying mechanism 2, enabling flexible scheduling and timely interruption of the conveying process. This facilitates rapid stopping of feeding when an abnormality is detected or adjustments are needed, preventing the continuous entry of problematic cigarette packs 100 and ensuring the orderliness of subsequent weighing and inspection processes and the controllability of the overall system.

[0064] like Figure 1 and Figure 2 As shown, the third conveying mechanism 3 also includes a third switch 34, which is communicatively connected to the controller and used to control the start and stop of the third conveying mechanism 3. The controller can remotely or automatically control the operating status of the third conveying mechanism 3, enabling flexible scheduling and timely interruption of the conveying process. This facilitates rapid stopping of feeding when an abnormality is detected or adjustments are needed, preventing the continuous entry of problematic cigarette packs 100 and ensuring the orderliness of subsequent weighing and inspection processes and the controllability of the overall system.

[0065] like Figures 1-4 As shown, the first conveying mechanism 1 also includes a first detection element 16, which is installed on the first conveying mechanism 1 and is communicatively connected to the controller. The first detection element 16 is used to detect the position of the cigarette pack 100 on the first conveying mechanism 1. By monitoring the conveying status of the cigarette pack 100 in real time, the controller can accurately obtain the signal indicating that the cigarette pack 100 has arrived, thereby coordinating the start and stop of the first conveying mechanism 1 and the triggering timing of subsequent weighing and scanning processes. This avoids idling of the mechanism or accumulation of cigarette packs 100, ensuring continuous and stable material flow and improving the automation level and operating efficiency of the overall system.

[0066] In this embodiment, the first detection element 16 is a photoelectric sensor. It senses the position of the cigarette pack 100 in real time through a non-contact detection method and transmits the signal to the controller. Based on this signal, the controller accurately determines the conveying status of the cigarette pack 100, thereby coordinating the start-stop rhythm of the first conveying mechanism 1 and the triggering timing of subsequent weighing and scanning processes. This effectively avoids idling of the mechanism, accumulation of cigarette packs 100, or empty detection stations, ensuring the continuity and stability of material flow and improving the overall system's automation level and operating efficiency.

[0067] like Figure 1As shown, the second conveying mechanism 2 also includes a second detection element 25, which is mounted on the second conveying mechanism 2 and is communicatively connected to the controller. The second detection element 25 is used to detect the position of the cigarette pack 100 on the second conveying mechanism 2. By monitoring the specific position of the cigarette pack 100 during the conveying process in real time, the controller can precisely control the weighing timing of the first weighing component 4 and the identification timing of the scanning component 5, avoiding detection errors caused by weighing or scanning too early or too late. Simultaneously, it prevents interference caused by multiple cigarette packs 100 entering the detection station simultaneously, ensuring that each cigarette pack 100 can independently and accurately complete the quality conformity test, guaranteeing the orderliness of the detection process and the reliability of the results. In this embodiment, the second detection element 25 is a photoelectric sensor.

[0068] like Figure 1 and Figure 2 As shown, the third conveying mechanism 3 also includes a third detection element 35, which is installed on the third conveying mechanism 3 and is communicatively connected to the controller. The third detection element 35 is used to detect the position of the cigarette pack 100 on the third conveying mechanism 3. By monitoring the conveying status of the cigarette pack 100 on the third conveying mechanism 3 in real time, the controller can accurately determine whether the defective cigarette pack 100 has reached the predetermined processing station, thereby triggering corresponding quality adjustment operations to avoid processing delays or process interruptions, ensuring the orderly handling of defective products and the overall system's operational continuity. In this embodiment, the third detection element 35 is a photoelectric sensor.

[0069] In summary, the working process of the cigarette pack quality conformity testing device provided in this embodiment is roughly as follows: First, the second conveying mechanism 2 located at the input end of the first conveying mechanism 1 conveys the cigarette pack 100 to the first conveying mechanism 1; when the first detection element 16 detects that the cigarette pack 100 has reached the predetermined position, the first conveying mechanism 1 stops operating, the first weighing element 4 weighs the cigarette pack 100 to obtain the first actual mass, and at the same time, the scanning component 5 identifies the label information of the cigarette pack 100 and extracts the labeled mass; the controller compares the first actual mass with the labeled mass, and if the mass meets the requirements, The cigarette pack 100 continues to be conveyed by the first conveying mechanism 1 to the second conveying mechanism 2 at its output end. If the quality does not meet the requirements, the controller activates the lifting and transfer mechanism 6 to transfer the unqualified cigarette pack 100 to the third conveying mechanism 3. After the quality adjustment operation of the cigarette pack 100 is performed on the third conveying mechanism 3, it is weighed again by the second weighing device 7 to confirm the adjustment result. Finally, the processed cigarette pack 100 is sent back to the first conveying mechanism 1 by the third conveying mechanism 3 and continues to be conveyed to the second conveying mechanism 2 at the output end of the first conveying mechanism 1, completing the entire detection and processing process.
