Description

PROCESS FOR MANAGING THE TOBACCO SUPPLY CHAIN

[001] This disclosure relates to a process for managing the tobacco supply chain, comprising processing tobacco leaves, quality grading and storage prior to the manufacture of the tobacco product. In particular, this disclosure relates to the automated analysis of tobacco through image generation and processing of images acquired in the tobacco supply chain. This disclosure also relates to a method for sorting tobacco, a tobacco analysis line, a method for packaging tobacco and a tobacco packaging line.

[002] Tobacco is mainly used for smoking, for example, in cigarettes and cigars, as well as in pipes. Traditional smoking articles, such as cigars and cigarettes, and aerosol-generating articles or non-burning heating cigarettes comprising tobacco are known in the art. Traditional smoking articles are lit at one end, causing them to burn slowly, and the resulting smoke is inhaled orally through the opposite end. In aerosol-generating articles, an aerosol-generating tobacco substrate is heated instead of burned. Tobacco can also be consumed as snuff, chewing tobacco, dipping tobacco, and snus.

[003] Tobacco leaves are grown and harvested by growers and then cured. Curing plays an important role in defining the final quality and character of the leaf. Each type of tobacco is cured differently. Once the leaves have been cured, the tobacco grower sorts them according to the position and quality of the stem and packages them separately in bales for distribution to the point of sale. At the point of sale, the leaves are Petition 870250081616, dated 11 / 09 / 2025, page 11 / 74 2 / 43 classified by expert leaf buyers who assess the quality of the leaves by carefully checking variations in color, texture, and aroma. Once the tobacco has been purchased, it is sent to a local processing factory where the leaves are further processed and dried for uniformity. After the drying process, the tobacco is pressed into boxes for worldwide shipment.

[004] The current tobacco leaf grading / classification method known at the point of sale is based on human knowledge and experience and is common in the production of tobacco blends for cigarette production.

[005] For the classification of tobacco leaves, hyperspectral imaging technology is also known to be employed.

[006] For example, document US2012250025A1 discloses a method and system for classifying agricultural products, such as tobacco bales, using hyperspectral imaging and analysis. The system includes a light source to provide a light beam, an interferometer or prism array to disperse electromagnetic radiation emitted from the agricultural product into a corresponding spectral image, a light measuring device to detect component wavelengths within the corresponding spectral image, and an operable processor to compare the detected component wavelengths with a database of previously classified agricultural products to identify and select a grade for the agricultural product.

[007] Document WO2014078862A1 discloses a method and system for mixing agricultural products, such as tobacco, using hyperspectral image generation and analysis. At least one region along an agricultural product sample is scanned using at least one light source of different wavelengths. Petition 870250081616, dated 11 / 09 / 2025, page 12 / 74 3 / 43 wave. Hyperspectral images are generated from at least one region. A spectral fingerprint for the agricultural product sample is formed from the hyperspectral images. A plurality of agricultural product samples is blended based on the spectral fingerprints of the samples according to parameters determined by running a blending algorithm.

[008] Document US2022369687A1 discloses a method for producing shredded tobacco for cigarettes and other green tobacco leaf products, comprising steps in a pre-industrial phase and steps in an industrial phase at a threshing plant that receives green tobacco leaves from producers.

[009] In this field, it would be desirable to improve the integration of imaging technology along the tobacco supply chain in order to increase control and accuracy over the chemical composition (e.g., total alkaloids, reducing sugars and moisture) and quality properties of tobacco leaves, blends and products, in particular, but not exclusively, for the manufacture of aerosol-generating articles.

[00146] The examples will now be further described with reference to the figures, in which: Petition 870250081616, dated 11 / 09 / 2025, page 42 / 74 33 / 43 Figure 1 is a flowchart that schematically shows a tobacco supply chain; Figures 2A and 2B are a graphical representation of the flowchart in Figure 1; Figure 3 shows a side view of a tobacco analysis line implemented in the tobacco supply chain of Figures 1, 2A and 2B; Figure 4 shows a tobacco packaging line implemented in the tobacco supply chain of Figures 1, 2A and 2B.

[00147] Figures 1, 2A and 2B show a tobacco supply chain. Tobacco plants are grown and harvested by growers, then the tobacco leaves are cured (Figures 1 and 2A, letter A). Each type of tobacco may be cured differently. Once the tobacco leaves have been cured, the tobacco grower sorts them by human visual inspection and according to the position and quality of the stem. The tobacco leaves are then bundled (Figures 1 and 2A, letter B) into bales 1 for distribution to points of sale.

[00148] At the point of sale, tobacco bales 1 are transported along the purchasing and sorting lines where said tobacco bales 1 are visually inspected by leaf specialists and then automatically analyzed through image generation and processing of images acquired using hyperspectral imaging technology (Figures 1 and 2A, letter C). The automatic analysis provides characteristics of the tobacco in the scanned tobacco bales 1. The characteristics comprise chemical characteristics of the tobacco, i.e., moisture, total alkaloids and reducing sugars, and optical properties of the tobacco, i.e., colors. These characteristics are reviewed, Petition 870250081616, dated 11 / 09 / 2025, page 43 / 74 34 / 43 by an operator or automatically through an algorithm, and the tobacco bales 1 are grouped into mixing sets 2 (Figures 1 and 2A, letter D) according to the revised characteristics.

[00149] Figure 3 shows details of a tobacco analysis line 3 configured to select tobacco on one of the purchase and selection lines. The tobacco analysis line 3 comprises an analysis conveyor 4 configured to feed the tobacco bales 1 one after the other in sequence along a feed direction FD. In the non-limiting example of Figure 3, the analysis conveyor 4 comprises a sequence of conveyor belts placed one after the other.

[00150] A structure 5 is installed near the analysis conveyor 4, and an upper part of said structure 5 is positioned above the analysis conveyor 4. The upper part carries an optical sensor 6 and an image generation scanner 7. The optical sensor 6 and the image generation scanner 7 are also schematically represented in Figure 2A.

[00151] The optical sensor 6, like a laser sensor, is mounted and oriented so as to be directed towards the tobacco bales 1 moving along the analysis conveyor 4 and to detect a height of the tobacco bales 1 placed on the analysis conveyor 4. The detection of the heights of the tobacco bales 1 can be performed while the tobacco bales 1 move along the tobacco analysis line 3 or while each box stops in front of the optical sensor 6. The optical sensor 6 is operationally connected to a control unit 8 and transmits to the control unit 8 a signal related to a distance from the optical sensor 6 to the tobacco bale 1. The control unit 8 is programmed or configured to determine a height of the detected bale 1 from such a signal.

[00152] Normally, the dimensions of the bales 1 depend on Petition 870250081616, dated 11 / 09 / 2025, p. 44 / 74 35 / 43 origin where they come from and all bales 1 from the same origin have similar dimensions. Examples of dimensions are listed in Table 1 below. Table 1 Origin 1 Origin 2 Length 1100 to 1250 mm 750 to 850 mm Width 700 to 800 mm 600 to 700 mm Height* 600 to 700 mm 400 to 500 mm Number of strips 4 5 / 6

[00153] Therefore, control unit 8 is programmed or configured to identify, from the detected height, a bale type 1 among a plurality of classified types of different sizes.

[00154] The image-generating scanner 7 is mounted and oriented so as to be directed towards the tobacco bales 1 moving along the analysis conveyor 4 and is operationally connected to the control unit 8. The image-generating scanner 7 is a hyperspectral image-generating scanner comprising a hyperspectral camera 9 and an optical camera 10. The image-generating scanner 7 also comprises one or more light sources, not shown in the drawings, to illuminate a tobacco surface to be scanned. The hyperspectral camera 9 collects and processes information from the entire electromagnetic spectrum to obtain the spectrum for each pixel in the image of a scene for the purpose of identifying the chemical characteristics of the tobacco in the tobacco bale 1, i.e., moisture, total alkaloids, and reducing sugars. The optical camera 10 is an RGB (Red Green Blue) camera and provides colors of the tobacco in the tobacco bale 1.Optical camera 10 is also configured to read an optically readable label. Petition 870250081616, dated 11 / 09 / 2025, p. 45 / 74 36 / 43 machine, like a barcode or a QR code.

[00155] The image generation scanner 7 is mounted on the frame 5 by means of a motion mechanism 11, which is shown schematically in Figure 3. The motion mechanism 11 carries the image generation scanner 7 and is configured to adjust a height of the image generation scanner 7, i.e., a distance of the image generation scanner 7 from the analysis conveyor 4 that supports the bales 1.

[00156] The control unit 8 is programmed or configured to control the motion mechanism 11 and to adjust the height of the image-generating scanner 7 as a function of the detected height of the tobacco bale 1 to be scanned so that a distance of the image-generating scanner 7 from a surface of the bales 1 is maintained within a range, even if the bales 1 to be scanned have different dimensions. According to variant embodiments, not shown in the drawings, instead of or in addition to adjusting the height of the image-generating scanner 7, a height of the tobacco bales 1 on the analysis conveyor 4 and / or a height of the analysis conveyor 4 may be adjusted.

[00157] Since there is a plurality of classified bale types of different sizes 1, the motion mechanism 11 is configured to move the image generation scanner 7 between a plurality of predefined heights, each corresponding to an identified bale type 1. For example, the image generation scanner 7 is moved to a lower position to scan a small bale T represented by the dashed line in Figure 3 (Origin 2 in Table 1) and to a higher position to scan a larger bale 1 represented by the solid line in Figure 3 (Origin 1 in Table 1).

[00158] The movement mechanism 11 is also provided with Petition 870250081616, dated 11 / 09 / 2025, page 46 / 74 37 / 43 a device for fine-tuning the position of the image-generating scanner 7. Once the image-generating scanner 7 is in the upper or lower position, the control unit 8 is programmed or configured to control the fine-tuning device to move the image-generating scanner 7 closer to each of the predefined heights.

[00159] When a tobacco bale 1 moves under the optical sensor 6, the control unit 8 determines the height of the detected bale 1 from the signal coming from the optical sensor 6 and controls the motion mechanism 11 to adjust the height of the image generation scanner 7. The control unit 8 is also operatively connected to the analysis conveyor 4 to move said analysis conveyor 4 and the tobacco bales 2.

[00160] Next, while the tobacco bale 1 moves under or stops under the imaging scanner 7, the control unit 8 acquires images through the imaging scanner 7 and processes the acquired images to calculate the moisture, total alkaloids, reducing sugars, and colors of the tobacco in the scanned tobacco bale 1. Additionally, the RGB camera reads a machine-readable optical label 12 (e.g., a QR code) that is placed on each bale 1 and contains bale 1 identification data. The hyperspectral imaging scanner analyzes how the surface of the leaves reflects or absorbs light. The light source shines light on the tobacco leaves, and then the hyperspectral camera scans the reflected light across a wide range of wavelengths, generating a spectrum that can then be related to the chemical content.

[00161] The characteristics (moisture, total alkaloids, reducing sugars, colors) of each bale 1 are associated with the identification data of the same bale 1 and, as disclosed above, the Petition 870250081616, dated 11 / 09 / 2025, page 47 / 74 38 / 43 bales of tobacco 1 are sorted and grouped into mixing sets 2. The control unit 8 can also be programmed or configured to correlate tobacco colors to a tobacco grade quality.

[00162] The characteristics, along with the identification data, are transmitted to the processing plants where the mixing sets 2 are sent for mixing (Figures 1 and 2A, letter E).

[00163] As schematically represented in Figure 2B, in processing plants, the bales 1 are broken up and the tobacco leaves are processed (Figures 1 and 2B, letter F). The processing comprises: mixing, conditioning and drying the tobacco.

[00164] After processing, the tobacco mixtures are packaged. Boxes 13 are filled (Figures 1 and 2B, letter G) with tobacco and weighed (Figures 1 and 2B, letter J). Boxes 13 are made of cardboard, in the shape of a parallelepiped, and are open at the top. Boxes 13 comprise flaps 14 that project from the side walls of box 13, and the flaps 14 are configured to close the top of box 13.

[00165] Figure 4 shows a packaging line 15 configured for packaging tobacco blends. The packaging line 15 comprises a packaging conveyor 16 configured to feed the boxes one after the other in sequence along a conveyor direction CD. The packaging conveyor 15 of the illustrated and non-limiting embodiment comprises a plurality of conveyors positioned one after the other. The packaging line 15 comprises a filling machine 17 placed above a first conveyor and configured to fill the boxes 13 with tobacco.

[00166] Downstream from the filling machine 17, a press 18 is located Petition 870250081616, dated 11 / 09 / 2025, page 48 / 74 39 / 43 above a second conveyor of the packaging conveyor 16 and said press 18 is configured to press the tobacco into boxes 13 (Figures 1 and 2B, letter H). Figure 4 shows, in solid line, the press 18 while pressing the tobacco into box 13 and the same press 18, in dashed line, in a rest position spaced from box 13.

[00167] An optical sensor 19 is located along the packaging conveyor 16, downstream of the press 18 in relation to the transport direction CD. The optical sensor 19 is mounted on a structure 20 that extends above the packaging conveyor 16 and is configured to detect a top surface of the compressed tobacco filling the boxes 13. The optical sensor 20 is operationally connected to a control unit 21 of the packaging line 15. The control unit 21 receives signals from the optical sensor 19 and is configured or programmed to detect a height or position of the top surface of the compressed tobacco in the boxes 13 and also of the tabs 14. The control unit 21 is also configured to control and move the packaging conveyor 16 and the boxes 13 and to control the filling machine 17 to fill the boxes 13.

[00168] Downstream of the optical sensor 19, the packaging line 15 comprises a hyperspectral imaging scanner 22 which is mounted on the structure 20 above the packaging conveyor 16. The hyperspectral imaging scanner 22 comprises a hyperspectral camera 23 and one or more light sources to provide a light beam to illuminate the tobacco while it is being scanned. The hyperspectral imaging scanner 22 further comprises an RGB optical camera 24. The hyperspectral imaging scanner 22 of the packaging line 15 may be per se known and / or may be of the same type as the hyperspectral imaging scanner 9 of the tobacco analysis line 3. Petition 870250081616, dated 11 / 09 / 2025, page 49 / 74 40 / 43

[00169] The hyperspectral camera 23 collects and processes information from the entire electromagnetic spectrum to obtain the spectrum for each pixel in the image of a scene with the aim of identifying the chemical characteristics of tobacco in boxes 13, that is, moisture, total alkaloids and reducing sugars. The RGB optical camera 10 is an RGB (Red Green Blue) camera and provides tobacco colors in boxes 13.

[00170] The hyperspectral imaging scanner 22 is mounted on the structure 20 by means of a motion mechanism 25, which is schematically represented in Figure 4. The motion mechanism 25 carries the imaging scanner 22 and is configured to adjust a height of the imaging scanner 22, i.e., a distance of the imaging scanner 22 in relation to the analysis conveyor 4 that supports the boxes 13 and in relation to the upper surface of the compressed tobacco in the boxes 13, as a function of the height of the upper surface of the tobacco in the boxes detected by the optical sensor 19.

[00171] The control unit 21 is programmed or configured to control the motion mechanism 25 and to adjust the height of the image-generating scanner 22 according to the detected height of the upper surface of the compressed tobacco in the boxes 13 to be scanned so that a distance of the image-generating scanner 22 from the upper surface is maintained within a range, even if the level of tobacco in the boxes 13 is different from one box to another (for example, in case of a change in the type of tobacco). For example, the height of the image-generating scanner 22 is adjusted to achieve a predefined distance from the upper surface of the compressed tobacco between 15 cm and 25 cm.

[00172] If boxes 13 can be classified according to a plurality of standard sizes or if the same boxes are Petition 870250081616, dated 11 / 09 / 2025, page 50 / 74 41 / 43 filled at different standard tobacco levels, the motion mechanism 25 is configured to move the image-generating scanner 22 between a plurality of predefined heights, each corresponding to an identified type of box 13 or tobacco level.

[00173] When a tobacco box 13 moves below or stops in front of the optical sensor 19, the control unit 21 determines the height of the top surface of the tobacco in the box 13 from the signal coming from the optical sensor 19 and controls the motion mechanism 25 to adjust the height of the image-generating scanner 22. The control unit 21 is also operatively connected to the packaging conveyor 16 to move said packaging conveyor 16 and the boxes 13.

[00174] The control unit 21 can also determine a height of the tabs 14 of the box 13 and adjust the height of the image generation scanner 22 to avoid interference with the tabs 14.

[00175] Next, while box 13 moves under or to under the image-generating scanner 22, the control unit 21 acquires images through the image-generating scanner 22 and processes the acquired images to calculate the moisture, total alkaloids, reducing sugars, and colors of the tobacco in box 13 (Figures 1 and 2B, letter I).

[00176] These characteristics (moisture, total alkaloids, reducing sugars, colors) of the tobacco in each box 13 are analyzed by control unit 21 and the tobacco in boxes 13 is classified according to one of a plurality of classes and through a calibration model. This is a digital classification that is used to give quality ratings to the boxes of tobacco 13 and which can then be used by blenders or tobacco manufacturers to optimize which tobacco is going into which final blend. Control unit 8 can also be programmed or configured to Petition 870250081616, dated 11 / 09 / 2025, page 51 / 74 42 / 43 correlate the colors of tobacco to a quality grade of tobacco.

[00177] Downstream of the image-generating scanner 22, the packaging line 15 comprises a weighing unit 26. In the illustrated embodiment, the weighing unit 26 is part of one of the conveyors and is configured to weigh the box 13 located on said conveyor. The weight can be provided to an operator at the weighing unit 26, for example, via a display, and the operator can add / remove tobacco from the box 13 to finely adjust the weight of the box 13.

[00178] After weighing and adjusting the weight, box 13 is transported to an additional press 27 (not shown in Figure 2B) located downstream of the weighing unit 26. The control unit 21 is operatively connected to the additional press 27 and is configured to control said additional press 27 to press the tobacco into boxes 13 after weighing and before closing box 13 by folding the flaps 14.

[00179] Boxes 13 are sent to tobacco manufacturers or tobacco product manufacturers (Figures 1 and 2B, letter K) and the characteristics of the tobacco together with the tobacco quality classification in the boxes are communicated to the tobacco manufacturers or tobacco product manufacturers.
