Description

Technical Field

[0001] This invention belongs to the field of cigarette production testing technology, specifically relating to a multi-hopper integrated testing method, device, equipment, and medium. Background Technology

[0002] In the quality control stage of cigarette production, the physical performance testing of cigarette products such as cigarette sticks and filters is a crucial process to ensure product quality. This requires precise testing of multiple indicators, including length, diameter, circumference, draw resistance, and hardness, using a comprehensive testing platform. Before testing, a quantitative sample must be placed in a hopper for feeding. The feeding and testing process control methods directly determine the overall sampling efficiency and testing accuracy. Currently, in the comprehensive cigarette testing process, traditional feeding methods, supporting equipment, and control logic all have many technical defects, resulting in low automation, cumbersome operation, and insufficient equipment utilization. This makes it difficult to meet the high-efficiency sampling requirements of large-scale cigarette production. Specific problems are as follows:

[0003] ① Traditional testing methods rely heavily on manual labor and have low process efficiency. Current physical testing methods for cigarette products mostly employ manual feeding with a single hopper. Each batch of samples requires operators to manually add samples multiple times and manually trigger the test start command. Furthermore, the testing process is executed on a standby basis, with subsequent operators waiting for the previous batch of samples to be tested before they can add samples. The testing time is uncertain, and there is often a gap in equipment operation between the completion of the test and the addition of the next batch of samples. This not only significantly increases the workload of operators but also severely reduces the overall efficiency of sampling inspection. In addition, the randomness of manual operation can easily lead to feeding errors, affecting the stability of the testing process.

[0004] ② Existing multi-hopper detection devices have structural design flaws, resulting in low space utilization and low efficiency. While automated multi-hopper feeding devices adapted to integrated testing platforms have emerged on the market in an attempt to solve the efficiency problem of manual feeding, the hopper arrangement and motion structure design of such devices have obvious defects: only one side of the hopper can maintain an upward-facing working state to realize sample placement and pushing for testing, while the other side of the hopper faces downward and cannot be used for feeding, resulting in a serious waste of feeding space; moreover, if a full hopper is reversed to the rear of the device before the feeding and testing are completed, samples are prone to scattering into the equipment, which can lead to equipment jamming, difficulty in internal cleaning, and other malfunctions, interrupting the testing process; at the same time, this type of structure cannot support personalized testing needs such as sample interleaving testing, designated testing, and random testing, and the device has poor scenario adaptability.

[0005] ③ The detection device's functions are not fully integrated, which can easily lead to misjudgment and inconvenience in operation. Existing multi-hopper detection devices lack comprehensive auxiliary function modules and are not equipped with effective empty material detection, hopper identification, and pusher plate position detection functions. This can easily lead to problems such as empty start of the integrated test bench, inaccurate identification of hopper numbers, and inability to monitor the pusher plate pushing status in real time, further reducing detection efficiency. In addition, the hoppers mostly adopt a disc-shaped arrangement design, which is not convenient for operators to continuously feed materials multiple times, resulting in poor operation convenience. At the same time, the device lacks a dedicated cleaning structure, and dust, tobacco, and other impurities easily accumulate at the bottom of the buffer hopper and on the surface of the detection sensor, which can easily cause false alarms of empty material and distortion of sample detection signals, affecting detection accuracy.

[0006] ④ The detection and control logic is too simple, and the ability to adapt to different modes and manage processes is insufficient. Existing control methods for comprehensive cigarette testing lack flexible mode switching logic. Most methods do not have a function to switch between single-hopper and multi-hopper modes. When only a small number of samples need to be tested, the multi-hopper device still needs to be activated, resulting in operational redundancy and waste of equipment resources. Furthermore, the multi-hopper working mode lacks detailed testing logic, making it impossible to achieve precise binding testing of hoppers and samples based on different sample specifications and brands, or to achieve efficient cyclic testing of single-brand samples, making it difficult to adapt to the needs of different testing scenarios. At the same time, there is no independent enable / disable logic for hopper stations. When the device is running, it needs to traverse all hoppers, and even if some hoppers are empty, the station still needs to be moved, resulting in a significant waste of time and further reducing testing efficiency.

[0007] ⑤ Poor coordination between the device and the integrated test bench, and low level of automated control. The existing multi-hopper device lacks an efficient signal interaction and linkage control mechanism with the integrated testing platform. The device cannot adjust the feeding rhythm in real time according to the working status of the integrated testing platform, nor can it feed back data such as hopper status and sample information to the operation interface of the integrated testing platform in real time. It is difficult for operators to achieve visualized and intelligent management of the testing process. In addition, the device has poor hopper adaptability and cannot be adapted to both the cutting hopper and the roller hopper of the integrated testing platform at the same time. Special hoppers need to be replaced to complete the testing of different types of samples, which increases the complexity of the testing preparation work.

[0008] Patent CN116869217A discloses an online cigarette sampling device. By setting up a storage component with multiple hoppers on the side of the cigarette conveying channel, along with sampling, transport, and unloading components, it completes online sampling, temporary storage, and unloading / loading of cigarettes. This enables flexible testing of cigarette samples from the same or different batches, and by placing the testing equipment outside the production line, it solves the problems of scattered sampling and testing equipment occupying production line space in online cigarette testing. However, it still has drawbacks. The hoppers only provide temporary storage and batch transfer of samples, lacking the precise loading and testing linkage logic adapted to a comprehensive cigarette testing platform. Furthermore, the hoppers lack empty material detection, identification, and automatic cleaning functions, making it impossible to specify hopper activation or bind brand for testing. Additionally, the hopper structure lacks a design to prevent spillage and ensure the opening always faces upwards, easily leading to sample spillage and equipment jamming. It also cannot coordinate with the comprehensive testing platform to complete continuous and automated testing of the physical indicators of cigarettes and filters, resulting in a low level of automation and intelligence in the testing process.

[0009] Therefore, there is an urgent need for a more efficient comprehensive cigarette testing method and device to solve the problems of low efficiency and insufficient automation and intelligence in the current comprehensive cigarette testing. Summary of the Invention

[0010] The present invention aims to solve the problem of low efficiency in the current comprehensive testing of cigarettes.

[0011] The present invention solves the above-mentioned technical problems through the following technical means: A multi-hopper integrated detection method includes the following steps: S1. Initial mode selection: Select single hopper mode or multi-hopper mode on the operation screen of the integrated test bench; S2, Secondary Mode Selection: When S1 selects the multi-hopper mode, a secondary sub-mode selection is performed, choosing either the loop mode or the binding mode on the comprehensive test bench; when S1 selects the single-hopper mode, the system enters the traditional stand-alone detection mode of the comprehensive test bench, and the system will skip this step and subsequent steps. S3. Initial station judgment and hopper selection judgment; If the loop mode is selected, the initial station judgment is performed. If the initial station is not hopper 1, hopper 1 is automatically moved to the detection initial station to complete the station calibration; if the initial station is hopper 1, the process proceeds directly to the next step. If the binding mode is selected, the hopper selection judgment is performed first. If no hopper is selected, the process ends directly. If a hopper is selected, the initial station judgment is performed. If the initial station is not hopper 1, hopper 1 is automatically moved to the detection initial station to complete the station calibration; if the initial station is hopper 1, the process proceeds to the current hopper selection judgment. If the hopper is not selected, the process moves to the next station; if the hopper is selected, the process proceeds directly to the next step. S4. Push Detection: The equipment reads the identification tag of the current workstation hopper through a reader and displays the current hopper number on the operation screen in real time; it automatically turns on the pneumatic switch of the push plate to prepare for pushing the sample to the hopper of the comprehensive test platform; S5. Material detection in the transition hopper: Determine whether there is any material to be tested in the transition hopper; S6. Automatic cleaning and position detection: The cleaning air circuit is activated to clean the bottom of the transition hopper and the surface of the sensor. At the same time, the position of the push plate is detected by the magnetic switches at the start and end points of the push plate. S7, Station Switching: Performs hopper station switching operation.

[0012] The dual-mode design, combining initial and secondary selection, caters to both the traditional single-hopper testing needs and the high-efficiency multi-hopper testing requirements. The cyclical and binding modes adapt to different sample testing scenarios, significantly improving testing flexibility. The layered logic design of initial station judgment and hopper selection judgment enables automatic hopper station calibration and intelligent skipping of unselected hoppers, avoiding invalid station operations and reducing redundant testing time. It replaces the traditional manual operation of multiple feedings and manual start-ups, completely solving the problems of low efficiency and operational downtime in manual testing. Furthermore, the process incorporates detailed designs such as real-time hopper number display and pusher plate position detection, achieving visualization and monitoring of the testing process, effectively reducing operational error rates, and comprehensively improving the automation, efficiency, and standardization of cigarette sample physical testing.

[0013] Preferably, the single hopper mode in step S1 is a mode in which the integrated test bench's built-in hopper is used to perform testing, and the external multi-hopper feeding component is not working; the multi-hopper mode is a mode in which the external multi-hopper feeding component is used in conjunction with the integrated test bench to perform testing.

[0014] Preferably, the cyclic mode in step S2 is a mode that only adapts to a single specification or brand of sample and does not require selecting a hopper number, while the binding mode is a mode that selects a hopper number to match the corresponding sample brand number and performs testing only on the selected hopper.

[0015] The cyclic mode is suitable for high-efficiency batch testing of single-specification samples, simplifying the operation steps without the need to select hopper numbers and improving the testing efficiency of large batches of samples of the same specification. The binding mode achieves accurate matching between hopper numbers and sample brand numbers, and performs testing only on the selected hoppers, adapting to the simultaneous testing needs of multiple specifications and brands of samples, realizing accurate differentiation and targeted testing of different samples, solving the problem that traditional testing cannot handle multiple specifications of samples at the same time, balancing testing efficiency and accuracy, and adapting to diverse cigarette sampling conditions.

[0016] Preferably, the specific process of step S5 includes: determining whether there is material to be tested on the transition hopper; if there is no material to be tested on the transition hopper, the integrated testing station is not started, and the hopper is automatically moved to the next station. In the loop mode, it returns to S4, and in the binding mode, it returns to S3; if there is material to be tested on the transition hopper, the integrated testing station is started, and the normal process of physical testing of cigarette samples is executed.

[0017] When there is no material, it automatically moves to the next station and returns to the judgment; when there is material, it starts normal detection, realizing intelligent identification and processing of empty material, avoiding empty start of the comprehensive test station, effectively saving the invalid time of empty start, and improving the continuity of the detection process. At the same time, it clarifies the action triggering of empty material detection and the linkage logic of subsequent stations, making the connection between material detection steps and the overall detection process smoother, reducing the invalid operation loss of equipment, and further improving the overall detection efficiency.

[0018] Preferably, the automatic cleaning and position detection described in step S6 are performed synchronously after each sample pushing operation is completed, and the magnetic switch provides real-time feedback on the pushing process status or the pushing completion status of the pusher plate.

[0019] The automatic cleaning and position detection are executed after each sample push to promptly clean up dust and tobacco, effectively preventing false alarms of empty material caused by dust accumulation at the bottom of the buffer hopper and on the sensor surface, thus improving the accuracy of material detection. At the same time, the magnetic switch provides real-time feedback on the pushing process and completion status of the pusher, allowing operators to monitor the equipment's operating status in real time, facilitating timely detection and handling of pushing faults, reducing the probability of equipment jamming and operational errors, and improving the controllability of the detection process and the stability of equipment operation.

[0020] Preferably, the present invention also provides a multi-hopper integrated testing device employing the multi-hopper integrated testing method described in any of the above schemes, with an initial mode selection module for selecting a single-hopper mode or a multi-hopper mode on the operation screen of the integrated testing platform; The secondary mode selection module is used to perform secondary sub-mode selection when the primary mode selection module selects the multi-hopper mode, and selects the loop mode or the binding mode on the comprehensive test bench. The workstation judgment module is used to perform initial workstation position judgment and hopper selection judgment in loop mode or binding mode; The hopper identification and push module is used to display the current hopper information in real time on the operation screen and push the pneumatic switch to push materials to the hopper of the comprehensive test bench. The material detection module is used to determine whether there is any material to be tested on the transition hopper; The cleaning and detection module is used to clean the bottom of the transition hopper and the surface of the sensor, while simultaneously detecting the position of the magnetic switch at the start and end points of the push plate in real time. The workstation switching module is used to perform hopper workstation switching operations.

[0021] Each module has a clear responsibility and complementary functions, realizing a modular design of the testing process, which facilitates the later maintenance and functional upgrades of the equipment. Individual module failures can be repaired independently. At the same time, each module is equipped with a corresponding hardware structure, realizing precise adaptation between software functions and hardware entities, and ensuring the accuracy and stability of each step of the action. In addition, the design of the external multi-hopper feeding component makes the equipment more adaptable and can be flexibly used with a comprehensive testing platform.

[0022] Preferably, the initial mode selection module includes a comprehensive test bench, the workstation switching module includes an external multi-hopper feeding assembly, and the material detection module includes a transition hopper assembly; the comprehensive test bench includes a hopper interface, the external multi-hopper feeding assembly is detachably installed on the side of the comprehensive test bench, and the transition hopper is gradually located between the interface end of the hopper interface of the comprehensive test bench and the discharge end of the external multi-hopper feeding assembly.

[0023] Preferably, the external multi-hopper feeding assembly includes a gravity-type rotating hopper, a rotating chain, a geared motor, and a sample pushing mechanism. The sample pushing mechanism includes a rodless cylinder and a cigarette pusher plate. The gravity-type rotating hopper is fixed to the rotating chain, the geared motor is located at the top of the rotating chain, and the geared motor drives the rotating chain to perform vertical cyclic motion. The sample pushing mechanism is located above the geared motor. The cigarette pusher plate is connected to the output end of the rodless cylinder, and the cigarette pusher plate is set to correspond to the feed inlet of the transition hopper assembly. Magnetic switches are provided at both the starting and ending points of the movement of the cigarette pusher plate, and the magnetic switches are electrically connected to the control terminal of the integrated testing platform.

[0024] Preferably, the device further includes an electronic device, comprising a processor and a memory, wherein the memory stores a computer program, and when the processor executes the computer program, it implements the multi-hopper integrated detection method.

[0025] Preferably, the method further includes a computer-readable storage medium storing a computer program, which, when executed by a processor, is used to implement the multi-hopper integrated detection method.

[0026] The advantages of this invention are: (1) Significantly improved detection efficiency: Through automatic mode selection, automatic station calibration, intelligent identification of empty material, automatic skipping of unselected hoppers, automatic station switching, and the self-weight hopper opening always facing upwards, the traditional manual multiple feeding, manual start-up, and queuing operations are replaced, avoiding the invalid time such as empty start-up and equipment idle operation. At the same time, automatic cleaning after pushing is realized to prevent false alarms from affecting the continuity of the process. The entire process from operation to detection reduces manual intervention and significantly improves the overall efficiency of cigarette sampling inspection. (2) Stronger adaptability: The design includes single-hopper mode and multi-hopper mode, retaining the compatibility of the original single-hopper test bench, and adapting to traditional testing needs without modifying the equipment; the multi-hopper mode is further divided into cyclic mode and binding mode. The cyclic mode is suitable for large-batch and efficient testing of single-specification samples, while the binding mode realizes accurate matching and directional testing of hopper and sample brand number, and can process multiple specifications of samples at the same time, taking into account both batch testing efficiency and multi-specification testing needs, and adapting to different cigarette sampling conditions; (3) Intelligent monitoring: Each hopper is equipped with an identification tag, a magnetic switch for the push plate position provides real-time feedback, and an empty material sensor provides accurate detection, making the detection process visible and monitorable. Operators can keep track of the equipment's operating status in real time. At the same time, the structural design, such as the counterweight magnetic attraction that keeps the hopper opening facing upwards and the vertical circulation hopper that makes it easier to feed materials, ensures that actions such as sample pushing, hopper switching, and material detection are executed accurately, effectively reducing the probability of sample spillage, equipment jamming, and operational errors. (4) External design facilitates disassembly: The detection function is broken down into six modular designs. A single module can be repaired independently if it fails, which facilitates later maintenance and function upgrades. The external multi-hopper feeding component adopts a detachable design and can be flexibly used with the comprehensive test bench without changing the original test bench structure, which greatly improves the versatility and ease of use of the equipment.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example 1: This embodiment provides a multi-hopper integrated detection method.

[0031] See Figure 2 This application's multi-hopper integrated testing method is based on a multi-hopper integrated testing device. To facilitate understanding of the method, this embodiment first provides a preliminary analysis of the device. The multi-hopper integrated testing device in this embodiment includes: an integrated testing platform 1, an external multi-hopper feeding assembly 2, and a transition hopper assembly 3. See details... Figures 2-5 The comprehensive testing platform 1 is the core testing unit and the main testing component of the cigarette comprehensive testing device. It is the execution unit for testing the physical properties of cigarette products such as cigarette sticks 4, and can accurately test multiple indicators such as length, diameter, circumference, draw resistance, hardness, and ellipticity. The external multi-hopper feeding assembly 2 is externally mounted on one side of the comprehensive testing platform 1, including a gravity-driven rotating hopper 21, a rotating chain 22, a geared motor 23, a sample pushing mechanism 24, and an identification tag and reader 25. These components work together to achieve efficient and accurate feeding of the external multi-hopper feeding assembly 2. The transition hopper assembly 3 is located between the external multi-hopper feeding assembly 2 and the comprehensive testing platform 1, including a transition hopper 31, a material presence / absence detection mechanism 32, and a cleaning mechanism 33, forming a sample transport connection relationship of "external multi-hopper feeding assembly 2 → transition hopper assembly 3 → comprehensive testing platform 1".

[0032] See Figure 1 This embodiment of a multi-hopper integrated detection method includes the following steps: S1. Initial mode selection: Select single hopper mode or multi-hopper mode on the operation screen of the integrated test bench.

[0033] The specific process of step S1 includes: ① The operating end is the main control screen of the cigarette comprehensive testing platform 1. The operator selects the function area through the mode selection screen, choosing between single hopper mode and multi-hopper mode. After selection, the testing platform control system will synchronously issue instructions to drive the equipment to match the hardware start / stop and working logic of the corresponding mode.

[0034] ② Single Hopper Mode: Once selected, the integrated test bench 1 will only use its own native hopper as the sole feeding and testing station. The external multi-hopper feeding component 2 will be in standby and non-working state throughout the process. The equipment will operate according to the original logic of traditional single hopper testing, which is suitable for small batch, temporary sampling inspection and other testing scenarios that do not require multi-hopper assistance. ③ Multi-hopper mode: After selection, the control system of the integrated test bench 1 will start the external multi-hopper feeding component 2 to establish linkage control with the integrated test bench 1. The external multi-hopper feeding component 2 becomes the core feeding station, and the integrated test bench 1's built-in hopper interface 11 serves as a transition station for sample receiving and testing. The equipment will enter the multi-hopper collaborative testing logic and needs to continue to execute the subsequent S2 secondary sub-mode selection steps to adapt to the efficient testing scenario of large batches and multi-specification samples.

[0035] The operation logic of step S1 is directly related to the subsequent detection process, and the two modes are mutually exclusive. There is no need to disassemble or debug the equipment hardware. It retains the compatibility of the original single-hopper detection of the test bench, and can quickly switch to the multi-hopper high-efficiency detection mode to adapt to different cigarette sampling and inspection conditions.

[0036] S2, Secondary Mode Selection: When S1 selects the multi-hopper mode, a secondary sub-mode selection is performed, choosing either the loop mode or the binding mode on the comprehensive test bench; when S1 selects the single-hopper mode, the system enters the traditional stand-alone testing mode of the comprehensive test bench, and the system will skip this step and subsequent steps.

[0037] The specific process of step S2 includes: ① After the multi-hopper mode is selected in step S1, the control system of the integrated test bench 1 completes the start-up and self-test of the external multi-hopper feeding component 2, and provides two mutually exclusive options: cycle mode and binding mode. The operator selects the appropriate mode according to the actual situation; select cycle mode when testing a single specification and grade sample, and select binding mode when testing multiple specifications and multiple grades samples.

[0038] ② After selecting a mode, the test bench control system immediately receives the instruction, automatically matches the corresponding mode's working logic and interface configuration, and completes mode initialization: If the cycle mode is selected: the control system enables the detection permissions of all hopper stations by default, without requiring operators to select hoppers separately. It only supports the input of one sample specification or grade information. After completion, the equipment enters the detection preparation state of the cycle mode and can directly perform hopper loading operations. In this mode, the system enables all hopper stations by default and completes sample pushing and detection in a cycle according to the hopper number (each hopper has its own corresponding number due to the configuration of identification tag 25, such as No. 1, No. 2, etc.). The core realization is the expansion and reuse of hopper stations, which improves the batch detection efficiency of single samples.

[0039] If the binding mode is selected: The binding mode is a mode that adapts to the simultaneous testing of multiple specifications and brands of cigarette samples under the multi-hopper mode. It allows operators to selectively select hopper stations and individually match the corresponding sample brand number for each selected hopper station. The system only pushes the test to the hopper that has been selected and completed the brand binding. Unselected hoppers will be intelligently skipped. The core is to achieve one-to-one accurate binding between hopper and sample, which meets the needs of directional and differentiated testing of multiple specifications of samples.

[0040] Step S2, through precise configuration of two sub-modes—circular mode and binding mode—enables multi-hopper detection to meet the needs of large-batch, high-efficiency detection of single-specification samples, as well as the needs of directional, precise detection of multi-specification samples, thus adapting to the diverse working conditions of cigarette sampling inspection.

[0041] S3. Initial station judgment and hopper selection judgment; If the loop mode is selected, the initial station judgment is performed. If the initial station is not hopper 1, hopper 1 is automatically moved to the detection initial station to complete the station calibration; if the initial station is hopper 1, the process proceeds directly to the next step. If the binding mode is selected, the hopper selection judgment is performed first. If no hopper is selected, the process ends directly. If a hopper is selected, the initial station judgment is performed. If the initial station is not hopper 1, hopper 1 is automatically moved to the detection initial station to complete the station calibration; if the initial station is hopper 1, the process proceeds to the current hopper selection judgment. If the hopper is not selected, the process moves to the next station; if the hopper is selected, the process proceeds directly to the next step.

[0042] The specific process of step S3 includes: S31. When the loop mode is selected in step S2, only the initial station judgment is performed. The steps are as follows: The control system automatically reads the current station position information of the external multi-hopper feeding component 2 and identifies the hopper number currently in the detection initial station. The identification result is judged: If the hopper in the current initial station is hopper number 1, the station calibration is completed, the control system determines that step S3 has been completed, and directly enters the subsequent S4 pushing detection step; If the hopper in the current initial station is not hopper number 1, the control system issues a station movement command, drives the external multi-hopper feeding component 2 to drive the self-weight rotating hopper 21 to move through the rotating plate chain 22 until hopper number 1 is accurately returned to the detection initial station. After the station calibration is completed, the subsequent S4 pushing detection step is entered.

[0043] S32. When the binding mode is selected in step S2, the following steps are executed sequentially: Hopper selection judgment → Initial station judgment → Current hopper selection judgment. ① Hopper Selection Judgment: The control system reads the hopper selection record of the operator on the operation screen and determines whether there is a selected hopper station: If no hopper is selected, the control system determines that there is no valid detection station and terminates the current detection process directly; if there is a selected hopper, it determines that there is a valid detection station and continues to execute the next initial station judgment.

[0044] ② Initial station judgment: The logic is the same as the station judgment in the cycle mode. The control system reads the hopper number of the current detection initial station and judges: If it is hopper 1, the station calibration is completed and the system directly enters the next step to select and judge the current hopper; if it is not hopper 1, the system automatically drives the external multi-hopper feeding component 2 to move and accurately move hopper 1 to the detection initial station. After the calibration is completed, the system enters the third step.

[0045] ③ Current Hopper Selection Determination: The control system identifies the selection status of the hopper (Hopper No. 1) that has been returned to the initial station and determines whether it is a valid hopper selected by the operator. If the hopper is selected, it is determined to be a valid detection station, step S3 is completed, and the subsequent step S4 push detection is performed. If the hopper is not selected, the control system issues a station switching command to drive the external multi-hopper feeding component 2 to move the hopper to the next station. Then, it returns to this step to determine the selection status of the hopper at the new current station until a valid hopper that has been selected is identified, and then the process proceeds to step S4.

[0046] The entire S3 process is completed automatically by the control system without any manual operation: the cyclic mode only performs core station calibration to ensure the continuity of the batch testing process; the binding mode adds a double-layer selection judgment, which can intelligently skip unselected hoppers, reduce detection redundancy time, and lay the foundation for subsequent accurate push testing.

[0047] S4. Push Detection: The equipment reads the identification tag of the current workstation hopper through the reader and displays the current hopper number on the operation screen in real time; it automatically turns on the pneumatic switch of the push plate to prepare for pushing the sample to the hopper of the comprehensive test platform.

[0048] The specific process of step S4 includes: ① Hopper identification and information display: The control system triggers the reader 26 to read the identification tag 25 (UHF electronic tag is used in this embodiment) on the side of the hopper that is currently in the initial detection station, and quickly obtains the unique station number of the hopper; after reading, the control system transmits the current hopper number to the integrated test bench 1 in real time, so that the operator can view the current detection station information in real time and realize the visual tracking of the detection process.

[0049] ② The pneumatic switch of the push plate is activated to complete the push preparation: The control system sends an action command to the sample push mechanism 24, automatically turns on the pneumatic switch corresponding to the push plate, drives the pneumatic circuit to complete the pressure adjustment and action preparation, so that the cigarette push plate 242 is in the push ready state; at this time, the push plate is precisely aligned with the discharge port of the current station hopper and the inlet of the transition hopper 31, forming a smooth channel for sample push, which is ready for the subsequent smooth and accurate push of the sample from the external multi-hopper feeding component 2 to the hopper interface 11 of the comprehensive test platform.

[0050] The entire S4 process is fully automated, with no human intervention required. The hopper identification and push preparation actions are synchronized and seamlessly integrated. The real-time display of the hopper number enables precise traceability of the testing station, while the automatic control of the pneumatic switch ensures the timeliness and accuracy of the push preparation action. This avoids delays and errors caused by manual operation and provides a solid guarantee for the continuity of subsequent sample push and testing processes.

[0051] S5. Transition Hopper Material Detection: Determines whether there is any material to be tested on the transition hopper.

[0052] The specific process of step S5 includes: ① After S4 completes the hopper identification and push preparation, the control system immediately sends a detection command to the material presence detection mechanism 32 located at the bottom of the transition hopper, triggering the sensor to detect the material inside the transition hopper 31 and accurately identify whether there is a cigarette sample to be tested in the hopper.

[0053] ② The material detection mechanism 32 detects the material in real time and feeds the results back to the control system. The control system executes a two-choice process logic based on the feedback results: If the detection result is no material to be tested: the control system determines that the current workstation hopper is empty and does not issue a detection start command to the comprehensive test station 1. The comprehensive test station 1 remains in standby state. At the same time, it directly issues a workstation switching command to drive the external multi-hopper feeding component 2 to move the hopper to the next workstation. Subsequently, if the binding mode is selected, the process automatically returns to step S3 and re-executes the logic of whether the new workstation hopper is selected. If the loop mode is selected, the process automatically returns to step S4 and performs a new push detection.

[0054] If the test result indicates that there is material to be tested: the control system determines that the current workstation hopper is valid and immediately sends a test start command to the comprehensive test bench 1, triggering the comprehensive test bench 1 to start the normal process of physical testing of cigarette samples, and sequentially executes the testing and data recording of physical indicators such as cigarette length, diameter, circumference, draw resistance, and hardness.

[0055] Step S5 features fast response and accurate judgment. By switching workstations directly when there is no material and starting the test immediately when there is material, the logic design avoids the problem of empty start-up of the comprehensive test station 1 from the source, greatly saving ineffective running time. At the same time, it ensures the continuity of the effective sample testing process and improves the overall testing efficiency.

[0056] S5. Automatic cleaning and position detection: The cleaning air circuit is activated to clean the bottom of the transition hopper and the surface of the sensor. At the same time, the position of the push plate is detected by the magnetic switches at the start and end points of the push plate.

[0057] The specific process of step S6 includes: ① Automatic cleaning action execution: The control system sends a start command to the cleaning mechanism 33 located at the bottom of the transition hopper, triggering the air circuit control unit and cleaning nozzle of the cleaning mechanism 31 to work. The high-pressure airflow blows the bottom of the transition hopper 31 and the sensor surface of the material presence detection mechanism 32 in all directions, quickly removing dust, tobacco, debris and other impurities remaining during the detection process. This avoids the accumulation of impurities that may obstruct the sensor or affect the material detection accuracy in the hopper, thus preventing false alarms of empty material and material detection deviations from the source.

[0058] ② Real-time detection of pusher position: While performing the cleaning action, the control system collects the position signal of the pusher in real time through magnetic switches located at the starting and ending points of the cigarette pusher 242, accurately detecting the current status of the pusher; the magnetic switches feed back the position detection results to the control system and the operation screen of the integrated test bench in real time, clearly showing whether the pusher is in the pushing process or has been pushed and returned to its original position, so that the operator can keep abreast of the operation of the pushing mechanism in real time. If the pusher jams or fails to return to its original position, it can be warned and dealt with in a timely manner.

[0059] Step S6 involves simultaneous cleaning and position detection. The immediacy of the cleaning action ensures the cleanliness of the transition hopper 31 and the sensor, maintaining the accuracy of material detection. Real-time detection of the pusher position enables monitoring of the sample pushing mechanism 24, reducing the probability of equipment failure. The combination of these two actions provides a clean environment and stable equipment operation for subsequent station switching and a new round of sample pushing and detection, ensuring the continuity and stability of the overall detection process.

[0060] S7, Station Switching: Performs hopper station switching operation.

[0061] The specific process of step S7 includes: ①When the S6 automatic cleaning and position detection steps are completed, and the sample at the current workstation is pushed and detected, the control system confirms that the detection process at the current workstation is over and immediately sends a workstation switching command to the geared motor 23 of the external multi-hopper feeding component 2, triggering the multi-hopper component to enter the workstation movement state.

[0062] ② After receiving the command, the geared motor 23 drives the rotating plate chain 22 to rotate at a constant speed in the preset vertical circulation direction, which drives the self-weight rotating hopper 21 to move synchronously, so as to realize the precise switching of the hopper position; during the movement, the self-weight rotating hopper 21 relies on the cooperation of the counterweight and the rotating shaft to always keep the hopper opening facing upward, so as to avoid the sample from falling.

[0063] ③ After the plate chain moves to the next station and accurately aligns with the initial station for detection, the reduction motor 23 automatically stops running, completing a single station switch. The new hopper station is stably in the initial detection position, waiting for the process to connect.

[0064] ④ After the workstation switch is completed, if it is in loop mode, the control system will automatically return the detection process to S4, and then execute the process in loop according to S4-S7; if it is in binding mode, it will return to S3, perform the selection judgment, and then execute the process in loop according to S3-S7.

[0065] Example 2: This embodiment is the core device for implementing Embodiment 1. The multi-hopper integrated detection device in this embodiment includes: an initial mode selection module, a secondary mode selection module, a workstation judgment module, a hopper identification and pushing module, a material detection module, a cleaning detection module, and a workstation switching module.

[0066] The initial mode selection module and the secondary mode selection module are used to initially select between single-hopper mode and multi-hopper mode on the operation screen of the integrated test bench, and to secondaryly select between cyclic mode and binding mode under multi-hopper mode, including the integrated test bench 1; the station judgment module is used to perform initial station judgment and hopper selection judgment under binding mode, and to control the hopper that is not No. 1 to move to the initial detection station; the station switching module is used to control the hopper to complete the station switching until No. 1 hopper returns to the initial detection station; including a gravity-type rotating hopper 21, a rotating plate chain 22, and a reduction motor. 23. Sample pushing mechanism 24; The hopper identification and pushing module is used to read the hopper identification tag 25 through the reader 26 and display the hopper number on the operation screen, while controlling the pneumatic switch of the pushing plate to open; including identification tag 25 and reader 26; The material detection module is used to determine whether there is material in the transition hopper through the detection mechanism. If there is no material, the station switching is triggered. If there is material, the detection process of the comprehensive test bench is started; including transition hopper 31 and material presence / absence detection mechanism 32; The cleaning detection module is used to control the cleaning air path to perform cleaning action; including cleaning mechanism 33.

[0067] For details, please refer to Figure 2 The integrated testing platform 1 is the core testing unit, and the external multi-hopper feeding component 2 is externally and linkedly assembled on one side of the integrated testing platform 1; the transition hopper component 3 is located between the external multi-hopper feeding component 2 and the integrated testing platform 1, forming a sample transport connection relationship of "external multi-hopper feeding component 2 → transition hopper component 3 → integrated testing platform 1".

[0068] For details, please refer to Figure 2 and Figure 3The comprehensive testing platform 1 is the main testing unit of the cigarette comprehensive testing device. It is the execution unit for testing the physical properties of cigarette products such as cigarette sticks (4), and can accurately test multiple indicators such as length, diameter, circumference, draw resistance, hardness, and ellipticity. The comprehensive testing platform 1 has a reserved assembly position on its outer side for linkage assembly with the external multi-hopper feeding assembly 2. A hopper interface 11 is provided at the connection point between the two, which is detachably connected to the discharge end of the transition hopper assembly 3, providing a precise docking channel for sample transport. The comprehensive testing platform 1 integrates a control terminal, an operation screen, and various functional modules, enabling signal interaction and linkage control with the external multi-hopper feeding assembly 2 and the transition hopper assembly 3. It can also perform operations such as test data display, station identification, and test start / stop, making it the control and testing core of the entire device. The hopper interface 11 adopts a standardized docking structure. Its interface size, installation positioning, and signal interface all meet the assembly and transmission requirements of both the cutter hopper and the roller hopper (the cutter hopper and the roller hopper are two different dedicated hoppers with different functions on the integrated test bench 1. The cutter hopper is a hopper with an integrated rotating cutter, whose core function is to automatically cut the incoming whole cigarette into segments to prepare for subsequent testing; the roller hopper is a hopper with a cigarette-separating roller inside, whose core function is to smoothly convey, arrange, and separate individual samples). According to the testing requirements, the cutter hopper or the roller hopper can be quickly replaced without structural modifications to the integrated test bench 1 and the external multi-hopper feeding assembly 2. This allows one feeding device to be compatible with two types of testing hoppers, improving the versatility of the device and the testing efficiency.

[0069] See Figures 3-5 The external multi-hopper feeding assembly 2 is the core component of the device in this application, and it is detachably installed on the side of the integrated test bench 1. The external multi-hopper feeding assembly 2 includes a gravity-type rotating hopper 21, a rotating plate chain 22, a geared motor 23, a sample pushing mechanism 24, an identification tag 25, and a reader / writer 26; the components work together to achieve efficient and accurate feeding of the external multi-hopper feeding assembly 2.

[0070] For details, please refer to Figures 4-5The gravity-type rotating hopper 21 is the sample-bearing unit of the external multi-hopper feeding assembly 2, and is the direct storage component for cigarette test samples such as cigarette sticks 4. The gravity-type rotating hopper 21 includes multiple hoppers of uniform specifications, evenly spaced and fixed to the outside of the rotating plate chain 22. It is the key structure to ensure that the hopper opening always faces upward, operates stably with full material, and prevents sample spillage. The gravity-type rotating hopper 21 includes a hopper support arm 211, a hopper rotation shaft 212, a hopper counterweight 213, a hopper body 214, and a hopper magnet 215. All components work together, and with the dual effects of gravity counterweight and magnetic fixation, ensure that the hopper opening always faces upward when it moves vertically in a circular motion with the rotating plate chain 22. Each set of self-weight rotating hoppers 21 is fixedly equipped with an identification tag 25 and a reader / writer 26 on its outer side. The identification tag 25 is an ultra-high frequency electronic tag (UHF electronic tag is used in this embodiment, but other electronic tags can be selected according to the actual situation), and a corresponding reader / writer 26 capable of recognizing the UHF electronic tag, forming a stable signal interaction with the identification tag 25. The tag pre-stores the corresponding hopper number information, sample brand information, or detection parameter matching information, which facilitates the reader / writer 26 to quickly read the relevant information of the corresponding hopper.

[0071] See Figure 6 The hopper support arm 211 serves as the connection and support foundation for the entire self-weight rotating hopper 21. It has a rigid rod-shaped structure. One end is fixedly connected to the outer wall of the rotating plate chain 22, realizing the rigid connection between the entire hopper and the external multi-hopper feeding assembly 2. The other end is a free end with a reserved rotation assembly position, which rotates and cooperates with the hopper rotating shaft 212 to provide support for the rotational movement of the hopper body 214 and the hopper counterweight 213. At the same time, it transmits the cyclical motion power of the rotating plate chain 22, driving the entire hopper to complete the workstation switching.

[0072] See Figure 6 The hopper rotating shaft 212 is a rotating component of the hopper, which is installed at the rotating assembly position at the free end of the hopper support arm 211. It is rotatably engaged with the hopper rotating shaft 211, and its two ends are rotatably connected to the outer walls of the two ends of the hopper counterweight block 213. This allows the hopper counterweight block 213 to rotate synchronously with the hopper rotating shaft 212 as the center, relative to the hopper support arm 211, providing a mechanical basis for adjusting the direction of the hopper opening.

[0073] See Figure 6 The hopper counterweight 213 is a gravity balancing component of the hopper. It has a block-shaped structure, and its outer wall is rotatably fixed to the hopper rotation axis 212. Its weight is precisely calculated, and it can pull the hopper body 214 to rotate around the hopper rotation axis 212 by its own gravity. This ensures that no matter what position the rotating chain 22 moves the hopper, the open end of the hopper body 214 always faces upward, thus preventing sample spillage from a gravity perspective. See Figures 6-7The hopper body 214 serves as the direct sample-bearing structure, featuring a recessed open design. The open end is the sample inlet or outlet. The inner cavity of the recess is adapted to the shape of the cigarette 4, allowing for stable storage of quantitatively tested samples. Its bottom is fixed to the hopper magnet 215, forming an integrated structure. Under the gravitational balance of the hopper counterweight 213, the open end always faces upwards. Simultaneously, the magnetic attraction of the hopper magnet 215 ensures its fixed position, preventing the hopper from shaking or shifting during movement.

[0074] See Figures 6-7 The hopper magnet 215 is a magnetic fixing component for the hopper, made of magnetic material. It is fixed to the bottom of the hopper body 214 and detachably magnetically attracted to the upper wall of the hopper counterweight 213. Together with the hopper counterweight 213, it achieves gravitational balance. The magnetic attraction between the hopper magnet 215 and the hopper counterweight 213 ensures that the relative position of the hopper body 214 and the hopper counterweight 213 is fixed, preventing the hopper from rotating due to inertia during the start-up, stop, and movement of the rotating chain 22. This further ensures the stability of the hopper opening direction. At the same time, the magnetic connection is detachable, facilitating the disassembly, maintenance, and cleaning of the hopper.

[0075] The self-weight rotating hopper 21 forms a stable self-balancing rotating structure through the fixed support of the hopper support arm 211, the rotational cooperation of the hopper rotating shaft 212, the gravity balance of the hopper counterweight 213, and the magnetic attraction of the hopper magnet 215. It can achieve the goal of the hopper body 214 opening always facing upward without the need for additional electrical or pneumatic adjustment. It has a simple structure, high reliability, and is suitable for the vertical cyclic motion scenario of the rotating plate chain 22. All hoppers can carry samples at full load, maximizing the space utilization and continuous feeding of the hopper.

[0076] For details, please refer to Figures 4-5The rotating plate chain 22 is the circulating conveying component of the external multi-hopper feeding assembly 2. It is a vertical closed-loop plate chain structure, arranged parallel to the side wall of the integrated testing platform 1, and connected to the geared motor 23. It is a key component for achieving the switching of the self-weight rotating hopper 21 and ensuring continuous sample feeding. Powered by the geared motor 23, the rotating plate chain 22 can achieve low-speed, stable, and fixed-distance vertical cyclic movement. The speed is adjustable and can be adjusted according to the feeding rhythm. Multiple sets of self-weight rotating hoppers 21 are evenly spaced on its outer chain links. The fixed spacing is adapted to the hopper specifications, ensuring no interference between adjacent hoppers. Each rotation of the plate chain completes one station switch, with precise positioning. The vertical cyclic arrangement design of the rotating plate chain 22 ensures that half of the hoppers always face the feeding side, facilitating continuous feeding. Combined with the upward-facing opening of the self-weight rotating hoppers 21, it achieves full-load effective utilization of all hoppers, completely solving the problem of wasted space in traditional hopper structures. Meanwhile, the rotating plate chain 22 is detachable, making it easy to connect with the component rack without requiring modification of the integrated test bench 1, and making disassembly, maintenance and cleaning more convenient.

[0077] For details, please refer to Figures 4-5 The sample pushing mechanism 24 is the precise sample pushing execution component of the external multi-hopper feeding assembly 2. It is a key structure for transferring the cigarette 4 from the gravity-driven rotating hopper 21 to the transition hopper assembly 3. It includes a rodless cylinder 241 and a cigarette pusher plate 242, which are connected to form an integrated pushing structure. The rodless cylinder 241 is the power source of the mechanism, which can realize linear reciprocating motion. Its stroke is precisely matched with the feeding distance of the hopper, and it can smoothly drive the cigarette pusher plate 242 to complete the pushing and resetting actions. The cigarette pusher plate 242 is the pushing execution component. Its plate surface is adapted to the discharge port of the hopper body 214 and the inlet of the transition hopper 31. It can fit against the inner wall of the hopper to push the sample smoothly as a whole, avoiding sample tipping, jamming or damage. Magnetic switches are provided at the starting and ending positions of the cigarette pusher plate 242. The magnetic switches are electrically connected to the control terminal of the integrated testing platform to obtain the position of the cigarette pusher plate 242 and determine whether it is in the process of pushing or has been pushed. During operation, when the gravity-driven rotating hopper 21 moves to the designated feeding station, the rodless cylinder 241 drives the cigarette pusher plate 242 to extend, pushing the sample in the hopper into the transition hopper 31. After pushing, the pusher plate automatically resets, waiting for the next feeding station hopper. The entire process is automated, working in conjunction with the integrated testing platform 1 and the external multi-hopper feeding assembly 2 to achieve continuous, accurate, and efficient sample transfer, connecting the feeding and testing processes.

[0078] See Figures 2-5The transition hopper assembly 3 is a transfer component in the cigarette comprehensive testing device that connects the external multi-hopper feeding assembly 2 and the comprehensive testing platform 1. It is located between the discharge end of the gravity-type rotating hopper 21 and the hopper interface 11 of the comprehensive testing platform 1. The transition hopper assembly 3 includes a transition hopper 31, a material presence / absence detection mechanism 32, and a cleaning mechanism 33. It can not only achieve stable transfer and transportation of samples, but also complete empty material detection and impurity cleaning, ensuring the continuity and accuracy of the testing process.

[0079] For details, please refer to Figures 2-5 The transition hopper 31 is a long, slotted cavity structure adapted to the shape of cigarettes, with a smooth, burr-free inner cavity to prevent jamming and scratching during sample transport. Its inlet end is directly connected to the feeding station of the externally mounted multi-hopper feeding assembly 2 and precisely docks with the outlet of the gravity-type rotating hopper 21. The outlet end is a detachable structure that connects to the hopper interface 11 of the integrated testing platform 1, forming a closed sample transport path of "gravity-type rotating hopper 21 → transition hopper assembly 3 → integrated testing platform 1", ensuring stable sample transport without dropping.

[0080] For details, please refer to Figures 2-5 The material presence / absence detection mechanism 32 is located on the lower wall of the transition hopper 31 and is electrically connected to the control terminal of the integrated testing platform 1. It is a key component for realizing empty material detection and avoiding empty start-ups of the testing platform. This mechanism includes a dual-reflection fiber optic sensor and a photoelectric sensor as detection elements. The sensor probe is precisely oriented towards the center of the inner cavity of the transition hopper 31, and the probe is positioned to avoid the sample conveying path, so as not to interfere with the smooth transfer of cigarettes and to achieve non-contact and accurate detection of whether there is a sample in the hopper. When the sample pushing mechanism 24 smoothly delivers the sample into the transition hopper 31, the sensor detects the presence of a sample in the material and immediately sends a material presence signal to the integrated testing platform 1, triggering the subsequent detection process. If there is no sample in the transition hopper 31, the sensor quickly feeds back an empty material signal. Upon receiving the signal, the integrated testing platform 1 does not start the detection process, but simultaneously links the external multi-hopper feeding component 2 to automatically switch to the next self-weight rotating hopper 21 station to complete the replenishment and pushing, eliminating the efficiency loss caused by empty start-ups of the testing platform from the source, and ensuring the continuous and efficient connection between the feeding and detection processes.

[0081] For details, please refer to Figures 2-5The cleaning mechanism 33 is integrated into the lower wall of the transition hopper 31 and is linked to the integrated test bench 1 for automatic removal of tobacco, dust, and other debris from the inner cavity of the transition hopper 31 and the sensor surface, ensuring stable and reliable detection signals. This mechanism mainly consists of a cleaning nozzle and a matching cleaning air path. The nozzle's air outlet faces the bottom of the transition hopper 31 and the sensor surface of the material presence / absence detection mechanism 32. After each sample is pushed, air is supplied through the air path and ejected through the nozzle to purge and clean the inner cavity of the transition hopper 31 and the sensor probe, preventing impurities from accumulating and obstructing the sensor or affecting sample transport, thereby improving detection stability and device operational reliability.

[0082] Example 3: Accordingly, this embodiment also discloses a multi-hopper integrated detection device, including a processor and a memory; the memory is used to store a computer program, which is loaded and executed by the processor to realize the multi-hopper integrated detection method.

[0083] Example 4: Accordingly, this embodiment also discloses a multi-hopper integrated detection medium, wherein the computer-readable storage medium stores computer instructions, and the computer instructions cause the computer to execute the multi-hopper integrated detection method.

[0084] This application has the following advantages: (1) Significantly improved detection efficiency: Through automatic mode selection, automatic station calibration, intelligent identification of empty material, automatic skipping of unselected hoppers, automatic station switching, and the self-weight hopper opening always facing upwards, the traditional manual multiple feeding, manual start-up, and queuing operations are replaced, avoiding the invalid time such as empty start-up and equipment idle operation. At the same time, automatic cleaning after pushing is realized to prevent false alarms from affecting the continuity of the process. The entire process from operation to detection reduces manual intervention and significantly improves the overall efficiency of cigarette sampling inspection. (2) Stronger adaptability: The design includes single-hopper mode and multi-hopper mode, retaining the compatibility of the original single-hopper test bench, and adapting to traditional testing needs without modifying the equipment; the multi-hopper mode is further divided into cyclic mode and binding mode. The cyclic mode is suitable for large-batch and efficient testing of single-specification samples, while the binding mode realizes accurate matching and directional testing of hopper and sample brand number, and can process multiple specifications of samples at the same time, taking into account both batch testing efficiency and multi-specification testing needs, and adapting to different cigarette sampling conditions; (3) Intelligent monitoring: Each hopper is equipped with an identification tag, a magnetic switch for the push plate position provides real-time feedback, and an empty material sensor provides accurate detection, making the detection process visible and monitorable. Operators can keep track of the equipment's operating status in real time. At the same time, the structural design, such as the counterweight magnetic attraction that keeps the hopper opening facing upwards and the vertical circulation hopper that makes it easier to feed materials, ensures that actions such as sample pushing, hopper switching, and material detection are executed accurately, effectively reducing the probability of sample spillage, equipment jamming, and operational errors. (4) External design facilitates disassembly: The detection function is broken down into six modular designs. A single module can be repaired independently if it fails, which facilitates later maintenance and function upgrades. The external multi-hopper feeding component 2 adopts a detachable design and can be flexibly used with the comprehensive test bench 1 without changing the original test bench structure, which greatly improves the versatility and ease of use of the equipment.
