Detailed Embodiments

[0027] To make the above objects, features, and advantages of the present application more obvious and understandable, the following provides a detailed description of the specific embodiments of the present application with reference to the accompanying drawings. Many specific details are set forth in the following description to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0028] In the description of the present application, it should be understood that if terms such as "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. appear, the orientation or positional relationship indicated by these terms is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0029] In addition, if the term "and / or" appears, "and / or" is merely a description of the association relationship of associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this article generally represents an "or" relationship between the associated objects before and after. If terms such as "first" and "second" appear, these terms are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" can explicitly or implicitly include at least one of such features. In the description of the present application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0030] In the present application, unless otherwise clearly specified and limited, if terms such as "install", "connect", "join", "fix", etc. appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and can be the communication inside two elements or the interaction relationship between two elements, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0031] In this application, unless otherwise clearly defined and limited, if there is a description such as a first feature being "on" or "under" a second feature, its meaning can be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature can mean that the first feature is directly above or obliquely above the second feature, or simply indicates that the first feature has a higher horizontal height than the second feature. The first feature being "under", "beneath" and "underneath" the second feature can be that the first feature is directly below or obliquely below the second feature, or simply indicates that the first feature has a lower horizontal height than the second feature.

[0032] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or there can also be an intermediate element. If an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. If so, the terms "vertical", "horizontal", "up", "down", "left", "right" and similar expressions used in this application are only for the purpose of illustration and do not represent the only implementation.

[0033] In the process of processing cigarette products, the physical and chemical properties of the finished cut tobacco in all aspects are the key to ensuring the overall quality of the finished cigarettes. The key parameters affecting the production of the finished cut tobacco include, but are not limited to, length, width, moisture content, temperature, whether there is doubling, whether there is impurity, whole cut tobacco rate, and formulation uniformity, etc.

[0034] However, in the real-time monitoring of cut tobacco in related technologies, both the sampling operation and the inspection operation of the sampling inspection are carried out manually, resulting in a strong subjectivity in the sampling operation, and there are risks of incomplete, uneven sampling and insufficient sampling rate, which have a greater impact on the subsequent detection results and data stability; at the same time, the manual inspection method has a large labor intensity, and there are also defects such as strong judgment subjectivity and low efficiency, resulting in lower accuracy and referenceability of the inspection results for feedback to the adjustment of production parameters.

[0035] Please refer to Figures 1 to 5 , an embodiment of the present application provides a cut tobacco sampling inspection device 100. The cut tobacco sampling inspection device 100 includes a conveying mechanism 10 and a sampling mechanism 20. Among them, the conveying mechanism 10 is used to convey cut tobacco; the sampling mechanism 20 is disposed on one side of the conveying mechanism 10 along the conveying direction, and includes a driving member 21, a sampling assembly 22 and an inspection box assembly 23. The driving member 21 is connected to the sampling assembly 22 and drives the sampling assembly 22 to move between the conveying mechanism 10 and the inspection box assembly 23; the sampling assembly 22 is used to obtain the cut tobacco on the conveying mechanism 10, the inspection box assembly 23 is used to cooperate with the cut tobacco to form a sample to be inspected, and the sampling assembly 22 is used to obtain an inspection image of the sample to be inspected.

[0036] The cut tobacco sampling device 100 is used to sample the cut tobacco on the conveying mechanism 10 at various stages of cut tobacco production and obtain the image information of the sampled cut tobacco, so as to judge whether the cut tobacco meets the production standards at each stage through image analysis in the subsequent process.

[0037] The function of the conveying mechanism 10 is to convey the cut tobacco so as to convey the cut tobacco from one processing station to the next processing station. In these embodiments of the present application, the conveying mechanism 10 can be located between any two processing stations in the cut tobacco production and processing.

[0038] The sampling mechanism 20 is arranged on one side of the conveying mechanism 10 along the conveying direction, so that the sampling mechanism 20 can freely and randomly sample the cut tobacco located on the conveying mechanism 10 without affecting the conveying of the cut tobacco by the conveying mechanism 10. Exemplarily, in some embodiments, the conveying mechanism 10 conveys the cut tobacco in a horizontal straight line direction. At this time, the sampling mechanism 20 can be arranged at intervals on the left and right sides of the conveying mechanism 10, or the sampling mechanism 20 can also be arranged at intervals above the conveying mechanism 10.

[0039] The sampling mechanism 20 includes a driving member 21, a sampling component 22 and an inspection box component 23 to clamp and position the sampled cut tobacco to form a sample to be inspected. The sample to be inspected is intended to better display the physical and chemical properties of the cut tobacco and facilitate the subsequent analysis of the sample to be inspected.

[0040] The function of the driving member 21 is to drive the sampling component 22 to move, so that the sampling component 22 can move between the conveying mechanism 10 and the inspection box component 23, and between the sub-components of the inspection box component 23, to achieve random sampling of the cut tobacco located on the conveying mechanism 10, enable the randomly sampled cut tobacco to form a sample to be inspected in the inspection box component 23, drive the sampling component 22 to take a photo of the sample to be inspected to obtain an inspection image, restore the sample to be inspected after sampling is completed and send the cut tobacco back to the conveying mechanism 10 or the cut tobacco recycling box.

[0041] In some embodiments of the present application, the driving member 21 can be a component formed by a combination of multiple chutes and sliders, and the driving member 21 can move in three mutually intersecting directions through different chutes and sliders, thereby driving the sampling mechanism 20 to freely adjust its position in space.

[0042] The function of the sampling component 22 is to grab and photograph, so as to grab the cut tobacco located on the conveying mechanism 10 by using the sampling component 22 and make the sampling component 22 cooperate with the inspection box component 23 to form a sample to be inspected; at the same time, the sampling component 22 can be used to take a photo of the sample to be inspected, and then obtain the inspection image of the sample to be inspected.

[0043] Exemplarily, the way for the sampling component 22 to obtain the cut tobacco can be but not limited to grabbing and adsorption.

[0044] The function of the inspection box assembly 23 is to accommodate the cut tobacco and clamp and position the cut tobacco selected for sampling, so as to obtain a more stable and clear inspection image when taking pictures of the sample to be inspected subsequently.

[0045] In these embodiments of the present application, the sampling mechanism 20 randomly obtains the cut tobacco on the conveying mechanism 10, and moves to the position of the inspection box assembly 23 under the drive of the driving member 21, so that the randomly obtained cut tobacco cooperates with the inspection box assembly 23 to form a sample to be inspected, and then the sampling mechanism 20 obtains the inspection image of the sample to be inspected, thus realizing a single random inspection sampling.

[0046] For the cut tobacco random inspection device 100 according to the embodiments of the present application, by arranging the sampling mechanism 20 on one side of the conveying mechanism 10 along the conveying direction, and setting the sampling mechanism 20 to include a driving member 21, a sampling component 22 and an inspection box assembly 23, after randomly sampling the cut tobacco on the conveying mechanism 10 by the cooperation of the driving member 21 and the sampling component 22, it cooperates with the inspection box assembly 23 to form a sample to be inspected, and then the sampling component 22 obtains the inspection image of the sample to be inspected. In this way, by driving the manual sampling method of related technologies by the sampling mechanism 22, the automation degree of random inspection in the cut tobacco production process is improved, and the random inspection judgment standard can be made more objective, improving the accuracy and referenceability of the random inspection results.

[0047] In some embodiments, the sampling component 22 includes a positioning tooling 221 and a suction cup 222. The positioning tooling 221 is connected to the driving member 21, and the suction cup 222 is installed on the positioning tooling 221. The suction cup 222 is configured to form a micro-negative pressure environment at the output end.

[0048] The positioning tooling 221 is an installation member for the suction cup 222, and the suction cup 222 is connected to the driving member 21 through the positioning tooling 221. Among them, the positioning tooling 221 is connected to the driving member 21. The possible implementation manner is that the positioning tooling 221 and the driving member 21 can be detachably connected by means of a card slot, a buckle, a connecting member (screw bolt), etc., so that when the suction cup 222 needs to be replaced or repaired, the positioning tooling 221 can be directly removed and replaced or repaired as a whole; or, in some embodiments, it can also be set that the positioning tooling 221 and the driving member 21 are fixedly connected by welding or even integrally formed, so as to improve the structural consistency between the positioning tooling 221 and the driving member 21.

[0049] The suction cup 222 is installed on the positioning tooling 221. In these embodiments of the present application, the suction cup 222 can be installed on the side of the positioning tooling 221 facing away from the driving member 21, so as to facilitate the contact between the suction cup 222 and the cut tobacco and the inspection box assembly 23, thereby improving the adsorption effect of the suction cup 222.

[0050] The suction cup 222 is configured to form a micro-negative pressure environment at the output end to adsorb light items such as cut tobacco near the output end of the suction cup 222. At the same time, the grasping ability of the micro-negative pressure environment is limited and will not adsorb too much cut tobacco. That is to say, in these embodiments of the present application, the negative pressure amount of the micro-negative pressure environment at the output end of the suction cup 222 can be adjusted to adjust the sample size of the sampling.

[0051] The output end of the suction cup 222 is the port of the suction cup 222 facing away from the positioning tooling 221. It can be understood that the suction cup 222 is used to connect with the negative pressure generating component, and then a micro-negative pressure environment is formed at the position of the output end of the suction cup 222. Among them, the pipeline of the negative pressure generating component can be arranged in the driving part 21 or the positioning tooling 221 to reduce the influence of the pipeline on the movement of the driving part 21.

[0052] In these embodiments of the present application, a filter screen (not labeled) can be arranged at the output end of the suction cup 222, and the maximum diameter of the mesh holes of the filter screen is set to be smaller than the process calibration width of the cut tobacco, so as to reduce the risk that the cut tobacco is adsorbed into the pipeline of the negative pressure generating component under the action of negative pressure, and then block the pipeline or the mesh holes of the filter screen.

[0053] In some embodiments, the sampling assembly 22 further includes an industrial camera 223, and the industrial camera 223 is connected to the positioning tooling 221; the industrial camera 223 is used to obtain an inspection image of the sample to be inspected.

[0054] The function of the industrial camera 223 is to perform visual data acquisition on the sample to be inspected, that is, to obtain an inspection image of the sample to be inspected. In these embodiments of the present application, the lens orientation of the industrial camera 223 can be set to be consistent with the orientation of the output end of the suction cup 222 to simplify the setting of the control logic of the driving part 21.

[0055] In these embodiments of the present application, the industrial camera 223 can be arranged on the side wall of the positioning tooling 221, and the lens orientation of the industrial camera 223 is set to be consistent with the orientation of the output end of the suction cup 222.

[0056] In some embodiments, the inspection box assembly 23 includes a sample box 231 and a sample pressing piece 232. The sample box 231 includes a bottom wall 2311 and an opening 2312 opposite to the bottom wall 2311. The sample pressing piece 232 is pressed against the bottom wall 2311 from the opening 2312 and is used to cooperate with the bottom wall 2311 and the cut tobacco to form a sample to be inspected.

[0057] The function of the inspection box assembly 23 is to cooperate with the cut tobacco sampled by the sampling assembly 22 to form a sample to be inspected.

[0058] The sample box 231 is the main structure of the test box assembly 23, and its function is to hold the cut tobacco sampled by the sampling assembly 22, and cooperate with the sample pressing piece 232 to form a structurally stable sample to be tested after the sample pressing piece 232 is pressed in.

[0059] The sample box 231 includes a bottom wall 2311 and an opening 2312 opposite to the bottom wall 2311, which means that the sample box 231 is a semi-surrounding structure with one end open, and the hollow structure of the sample box 231 is used to place the cut tobacco. Among them, the cut tobacco randomly adsorbed by the sampling assembly 22 can be put into the internal space of the sample box 231 from one side of the opening 2312 and finally placed on the bottom wall 2311.

[0060] The sample pressing piece 232 is pressed from the opening 2312 against the bottom wall 2311 and is used to cooperate with the bottom wall 2311 and the cut tobacco to form a sample to be tested, which means that after the cut tobacco is put into the sample box 231, the sampling assembly 22 can grab the sample pressing piece 232 and press it into the internal space of the sample box 231 from one side of the opening 2312 of the sample box 231. At this time, the periphery of the sample pressing piece 232 contacts the inner wall of the sample box 231, and through the frictional engagement between the sample pressing piece 232 and the sample box 231, the sample pressing piece 232 and the bottom wall 2311 jointly press and position the cut tobacco in the sample box 231 to form a sample to be tested.

[0061] It can be understood that when subsequently using the sampling assembly 22 to obtain the inspection image of the sample to be tested, the sampling assembly 22 can take a photo of the sample to be tested through the side of the sample to be tested close to the sample pressing piece 232. In this way, the material of the sample pressing piece 232 can be set to glass, high-transparency plastic, etc., but not limited to these.

[0062] In these embodiments of the present application, the test box assembly 23 further includes a pressing piece accommodating box 233 for accommodating the sample pressing piece 232. Among them, the structure of the pressing piece accommodating box 233 is the same as that of the sample box 231 and is used to store the sample pressing piece 232, thereby providing protection for the sample pressing piece 232 in the unused state and reducing the risk of scratching and damage to the sample pressing piece 232.

[0063] In some embodiments, the sample box 231 further includes a partition 2313, and the partition 2313 divides the internal space of the sample box 231 into a plurality of mutually spaced sub-spaces 101; the number and arrangement of the sample pressing pieces 232, the number and arrangement of the suction cups 222, and the number and arrangement of the sub-spaces 101 match each other.

[0064] In the sample box 231, the partition 2313 is a plate structure intersecting with the bottom wall 2311, and the partition 2313 can cooperate with the side wall, the bottom wall 2311 and the opening 2312 of the sample box 231 to form a plurality of mutually independent sub-spaces 101 with one end open.

[0065] In this way, the internal space of the sample box 231 is divided into multiple independent sub-spaces 101, so that a sample box 231 can cooperate with multiple sample tablets 232 to form multiple independent samples to be tested. During subsequent testing, during the same sampling process, multiple independent samples to be tested can be inspected, and the results of this sampling can be judged by integrating the inspection results of multiple independent samples to be tested. Such a design method can further reduce the contingency of the sampling results and improve the credibility of the sampling inspection.

[0066] The number and arrangement of the sample tablets 232, the number and arrangement of the suction cups 222, and the number and arrangement of the sub-spaces 101 match. That is to say, the number of the sample tablets 232, the suction cups 222, and the sub-spaces 101 is the same and the arrangement is the same. In this way, when the sampling component 22 randomly grabs the cut tobacco, multiple suction cups 222 act simultaneously, adsorb and grab the cut tobacco at different positions on the conveying mechanism 10, and then move towards the sample box 231 under the driving action of the driving member 21. After adjusting the positions of the multiple suction cups 222 so that one suction cup 222 corresponds to one sub-space 101, control the multiple suction cups 222 to put the cut tobacco adsorbed by each into the corresponding sub-space 101; thereafter, the driving member 21 can drive the suction cups 222 to advance towards the direction close to the sample tablets 232 again. After making one suction cup 222 correspond to one sample tablet 232, adsorb the multiple sample tablets 232 through the multiple suction cups 222, and advance to the position of the sample box 231 again. After adjusting to make one sample tablet 232 correspond to one sub-space 101, press the multiple sample tablets 232 into the multiple sub-spaces 101 respectively, thereby forming multiple independent samples to be tested.

[0067] In these embodiments of the present application, during the pressing process of the sample tablets 232, since the multiple sample tablets 232 are respectively pressed in synchronously by the multiple suction cups 222, and as described above, the multiple suction cups 222 are respectively arranged on the positioning tooling 221, so that the multiple sample tablets 232 can be regarded as a whole pressing piece during the process of pressing towards the sample box 231. In this way, the planar overall pressure that can be used for the multiple sample tablets 232 presses the surfaces of the cut tobacco in each sub-space 101 to the same focal plane and keeps them fixed, so that when subsequently collecting inspection images of the cut tobacco in each sub-space 101 through the sampling component, it is possible to more quickly and simply use a long-focus lens with high resolution to focus and observe the overall structure, which can further improve the efficiency of obtaining inspection images.

[0068] In some embodiments, the partition plates 2313 are parallel to each other and are arranged at intervals along a straight line.

[0069] Each partition plate 2313 is parallel to each other and arranged at intervals along a straight line, that is, each sub-space 101 and each suction cup 222 are also arranged in sequence along a straight line. In this way, when randomly selecting cut tobacco through the sampling assembly 22, the driving member 21 can control the setting direction of the plurality of suction cups 222 to be perpendicular to the conveying direction of the conveying mechanism 10. Furthermore, the sampling assembly 22 can be used to suck cut tobacco at different positions on the same cross-section in the conveying direction for inspection, which can better control the variables in the inspection, so that the cut tobacco sucked into different samples to be inspected during the same spot check is generated in the same processing environment, which is more conducive to tracing the source of problems after inspection problems occur.

[0070] In some embodiments, the sample box 231 further includes a background light source (not shown in the figure), and the background light source is arranged on the bottom wall 2311 and is used to provide light to the bottom wall 2311.

[0071] The background light source is arranged on the bottom wall 2311. A possible implementation is that the bottom wall 2311 can also be set as a transparent material. At this time, the background light source can be arranged on both sides of the bottom wall 2311, that is, the background light source can be arranged in the internal space of the sample box 231 or outside the internal space of the sample box 231; in some embodiments, the bottom wall 2311 can be set as a non-transparent material. At this time, the background light source needs to be arranged in the internal space of the sample box 231 to provide backlight for the cut tobacco to be spot-checked, so that the industrial camera 223 can better visually capture the edge details of the cut tobacco, improving the resolution and information capture accuracy of the inspection images taken by the industrial camera 223.

[0072] In some embodiments, the driving member 21 is a six-axis robotic arm, and the conveying mechanism 10 is an on-line auxiliary belt conveyor.

[0073] The embodiment of the present application also provides a cut tobacco real-time inspection system, which includes a plurality of cut tobacco spot-check devices 100 provided in any of the foregoing embodiments. The cut tobacco spot-check device 100 is arranged downstream of the cut tobacco machine, and / or, the cut tobacco spot-check device is arranged downstream of the conditioning machine, and / or, the cut tobacco spot-check device is arranged downstream of the drying machine.

[0074] In these embodiments of the present application, by arranging the cut tobacco spot-check device 100 downstream of each step of cut tobacco production, the cut tobacco spot-check device 100 can be used to spot-check the cut tobacco after being processed in each step, and then judge whether there are problems and defects in the production quality of each part during the cut tobacco production and processing process, which is conducive to quickly tracing the source of the problem process and improving the efficiency of problem solving during the production process.

[0075] Exemplarily, in some embodiments, the number of the cut tobacco sampling devices 100 can be set to three, and the three cut tobacco sampling devices 100 are respectively arranged downstream of the cutter, downstream of the conditioning machine, and downstream of the dryer. In this way, when a sample with quality problems is detected by the cut tobacco sampling device 100 arranged downstream of the cutter, the problem can be quickly traced back to the cutter, so that the staff can quickly understand the root cause of the problem, improving the timeliness of problem discovery, which is beneficial to quickly adjusting production parameters and improving the product yield.

[0076] Please refer to Figures 1 to 6 , this embodiment of the present application also provides a cut tobacco real-time inspection method, and the cut tobacco real-time inspection method includes the following steps:

[0077] Step S1, control the driving member 21 to move above the conveying mechanism 10; Step S2, control the sampling assembly 22 to work and adsorb the cut tobacco located on the conveying mechanism 10; Step S3, control the driving member 21 to move above the inspection box assembly 23, and control the sampling assembly 22 to put the adsorbed cut tobacco into the sample box 231; Step S4, control the sampling assembly 22 to adsorb and place the sample pressing piece 232 into the sample box 231 to cooperate with the sample box 231 to press the cut tobacco tightly to form a to-be-inspected sample; Step S5, control the sampling assembly 22 to take a photo of the to-be-inspected sample to obtain an inspection image; Step S6, perform feature verification on the inspection image. If the visual parameters of the cut tobacco are normal, output a normal production signal. If the visual parameters of the cut tobacco are abnormal, issue an alarm and judge whether it meets the conditions for continuing production.

[0078] Among them, in step S6, if the visual parameters of the cut tobacco are abnormal, an alarm is issued and it is judged whether it meets the conditions for continuing production. That is to say, in this step, when the visual parameters of the cut tobacco are abnormal, there are the following two situations: One is that when the cut tobacco sampling device 100 completes a sampling operation and the visual parameter identification verification fails and seriously exceeds the safety range calibrated by the process standard, it can be judged in combination with the data in the historical major process accident library that it may lead to event grading, product downgrading or scrapping, output specific verification parameters, the safety range calibrated by the process standard, and the content of the supporting documents in the database, and output a stop production signal; The other is that when the cut tobacco sampling device 100 completes a sampling operation and the visual parameter identification verification fails, it can be judged in combination with the data in the historical high-frequency process event library that the process adjustment can be completed by adjusting the equipment parameters, and output specific parameter adjustment suggestions and signals.

[0079] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combinations of these technical features do not conflict, they should be considered as the scope recorded in this specification.

[0080] The embodiments described above only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
