[0002] During tobacco production, tobacco leaves need to be sorted by grade. Tobacco grade sorting is typically based on leaf size and maturity. Traditionally, tobacco leaf sorting is done manually. In this method, workers remove individual leaves from a pile and visually identify their size and maturity. Leaves that meet these criteria are then placed into designated bins.

[0003] While this traditional manual sorting method can achieve the ultimate goal, it is labor-intensive, inefficient, and carries the risk of misplaced tobacco leaves.

[0025] The embodiments of the present application are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference signs represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0026] A tobacco leaf sorting system is used to disperse tobacco leaves 400 arranged in piles multiple times, grade the dispersed tobacco leaves 400, and finally discharge tobacco leaves 400 of different grades from corresponding grade lines according to the grading results. Figure 1 and Figure 2 The shown parts include the loading and sorting section 1, the grading section 2 and the sorting and unloading section 3.

[0027] The feeding and sorting section 1 comprises a first sorting assembly 11 and a second sorting assembly 12. The first sorting assembly 11 performs a first dispersion of the tobacco leaves 400, causing the tobacco leaves 400 to have a first discreteness that facilitates sorting by the second sorting assembly 12. The tobacco leaves 400 then enter the second sorting assembly 12 at the first discreteness. The second sorting assembly 12 then performs a second dispersion of the tobacco leaves 400, causing the tobacco leaves 400 to enter the grading section 2 at a second discreteness that facilitates grading by the grading section 2.

[0028] Each tobacco leaf 400 will be transported to the sorting and unloading section 3 after grading, combined with Figure 7 As shown, the sorting and unloading part 3 has a sorting mechanism 31 and a unloading and conveying mechanism 32. Among them, the sorting mechanism 31 is set in series in multiples, and the unloading and conveying mechanism 32 is set below each sorting mechanism 31. Figure 8 As shown, any sorting mechanism 31 is capable of swinging downward about a horizontal axis, and each sorting mechanism 31 is configured to correspond to different grades of tobacco leaves 400. When tobacco leaves 400, graded by the grading unit 2, are transported to a corresponding sorting mechanism 31, the sorting mechanism 31 swings downward, forming a sorting channel between itself and the adjacent sorting mechanism 31, connecting to the corresponding discharge conveyor mechanism 32 below. This allows tobacco leaves 400 of the same grade to pass through the same sorting channel and fall into the same discharge conveyor mechanism 32. This arrangement allows multiple sorting mechanisms 31 to be combined with multiple discharge conveyor mechanisms 32 to sort tobacco leaves 400 of different grades.

[0029] Combine Figure 3 As shown, tobacco leaves 400 are fed into the inlet of the first sorting assembly 11 in a stacked form. The first sorting assembly 11 includes a first conveying mechanism 111 and a first sorting mechanism 112. The first conveying mechanism 111 is used to carry the tobacco leaves 400 in a first direction. The first sorting mechanism 112 is disposed above the first conveying mechanism 111 and forms a sorting channel 114 between the first conveying mechanism 111 and the first conveying mechanism 111 for sorting the tobacco leaves 400. The end of the sorting channel 114 near the upstream end of the first conveying mechanism 111 is defined as a first stacking area 113. The tobacco leaves 400 stacked in the first stacking area 113 have a first height. The end of the sorting channel 114 near the downstream end of the first conveying mechanism 111 has a second height lower than the first height.

[0030] When the stacked tobacco leaves 400 enter the sorting channel 114, the first sorting mechanism 112 is lower than the top of the tobacco leaves 400, so it can contact the top of the tobacco leaves 400 and flatten the stacked tobacco leaves 400, so that the tobacco leaves 400 are basically sent into the second sorting component 12 at a second height in a flat state.

[0031] Specific, combined Figure 3 and Figure 4 As shown, the first conveying mechanism 111 utilizes a synchronous belt drive mechanism or a conveyor roller mechanism. The first sorting mechanism 112 includes a first sorting base 1121, which is mounted above the first conveying mechanism 111. The first sorting base 1121 cooperates with the upstream end of the first conveying mechanism 111 to form the entrance of the sorting channel 114, and the downstream end of the first conveying mechanism 111 to form the exit of the sorting channel 114. Furthermore, a sorting paddle 1122 is provided on the first sorting base 1121. Driven by a first sorting driver 1123, the sorting paddle 1122 moves along a circular path corresponding to the outer wall of the first sorting base 1121, capable of abutting against a pile of tobacco leaves 400 entering the sorting channel 114. The paddle 1122 moves in an opposite direction to the first conveying mechanism 111 on one side of the circular path, thereby removing tobacco leaves 400 from the upper layer of the pile near the sorting surface to the rear of the conveying mechanism 111.

[0032] In a preferred embodiment of the present application, the first sorting base 1121 is tilted relative to the first conveying mechanism 111, such that the sorting channel 114, near the upstream end of the first conveying mechanism 111, has a third height that is higher than the first height. With this arrangement, the sorting paddle 1122 moves diagonally along the tilted circular path, with the height of the circular path gradually decreasing from the third height to the second height in the first direction. When the accumulated tobacco leaves 400 enter the sorting channel 114, the top portion of the accumulated tobacco leaves 400 will abut against the sorting paddle 1122 and be pushed to the rear. As the first conveying mechanism 111 continuously transports the accumulated tobacco leaves 400 in the first direction, at any given moment, the sorting paddle 1122 only contacts the top portion of the accumulated tobacco leaves 400. This ensures that the number of tobacco leaves 400 removed by the sorting paddle 1122 remains relatively constant, creating a layered peeling effect on the accumulated tobacco leaves 400. This material-selecting method can avoid separating a large number of tobacco leaves 400 at once, which may cause the peeled tobacco leaves 400 to interfere with the movement of other tobacco leaves 400 running along the first direction, thereby causing the accumulated tobacco leaves 400 to get stuck in the sorting channel 114, or the tobacco leaves 400 to become entangled and difficult to separate, thereby ensuring that the sorting channel 114 is unobstructed.

[0033] In this embodiment, the first sorting driver 1123 is composed of a synchronous belt and a synchronous pulley, and the sorting paddle 1122 is vertically fixed to the outer surface of the synchronous pulley.

[0034] like Figure 5 and Figure 6 As shown, the second sorting assembly 12 includes a second sorting base 121. The bottom end of the second sorting base 121 corresponds to the discharge end of the first sorting mechanism 112 and is configured as a second accumulation area 124. Due to the operation of the first sorting assembly 11, the tobacco leaves 400 in the second accumulation area 124 are more dispersed than in the first accumulation area 113. A carrier 122 is provided on the second sorting base 121. Driven by a second sorting driver 123, the carrier 122 runs along the outer wall of the second sorting base 121. The carrier 122 has a pointed tip 1221 that can penetrate and connect with some of the tobacco leaves 400 in the second accumulation area 124.

[0035] Specifically, the second sorting base 121 is positioned substantially vertically, or with its top end tilted slightly toward the grading section 2. The second sorting drive 123 includes synchronous pulleys fixed to the top and bottom ends of the second sorting base 121, and a synchronous belt configured to cooperate with the synchronous pulleys. Multiple carriers 122 are provided and evenly spaced along the outer surface of the synchronous belt along its length. The tips 1221 of the carriers 122 are positioned upward. At one end of the second sorting base 121 near the second stacking area 124, the second sorting drive 123 drives the carriers 122 upward, enabling the tips 1221 of the carriers 122 to pierce and connect with individual tobacco leaves 400 in the second stacking area 124, thereby lifting the tobacco leaves 400 into the grading section 2.

[0036] Driven by the second sorting drive 123, the carrier 122, carrying the tobacco leaves 400, is lifted along the second sorting base 121 and enters the stripping section 125. The stripping section 125 has a rotation point, causing the tip 1221, which was originally facing upward in the second accumulation area 124, to face downward after entering the stripping section 125, allowing the tobacco leaves 400 to be separated from the carrier 122.

[0037] Since a single carrier 122 can only pierce a single tobacco leaf 400 , at most only one tobacco leaf 400 can enter the grading section 2 at the same time.

[0038] In this embodiment, the grading unit 2 uses a visual detection device to scan the flat size of the incoming tobacco leaves 400 to determine different grades.

[0039] like Figure 7 and Figure 8As shown, the sorting mechanism 31 includes a fixed sorting base 311, on which are mounted a sorting conveying driver 312 and a sorting turning driver 313. The sorting conveying driver 312 is used to carry tobacco leaves 400 that have been graded by the grading unit 2, and one end of the sorting conveying driver is horizontally hinged to the sorting base 311.

[0040] The sorting and flipping actuator 313 has various structural forms. In this embodiment, the sorting and flipping actuator 313 is constructed as a cylinder, the actuator end of the cylinder is hinged to the sorting and conveying actuator 312, and the other end is hinged to the sorting base 311. The lifting action of the cylinder drives the sorting and conveying actuator 312 to flip around the hinged end with the sorting base 311. In other embodiments of the present application, the sorting and flipping actuator 313 uses a motor, one end of the sorting and flipping actuator 313 is fixed to the sorting base 311, and the actuator end of the sorting and flipping actuator 313 is coaxially fixed with the hinged end of the sorting and conveying actuator 312 and the sorting base 311, thereby driving the sorting and conveying actuator 312 to swing around a horizontal axis.

[0041] In this embodiment, the sorting mechanism 31 is arranged along a first direction, and multiple unloading conveyor mechanisms 32 are arranged parallel to each other along a second direction perpendicular to the first direction below the sorting mechanism 31. The unloading conveyor mechanisms 32 include unloading conveyor belts 321 arranged along the second direction, and unloading drive shafts 322 that extend through the multiple unloading conveyor belts 321. The unloading drive shafts 322 drive the multiple unloading conveyor belts 321 to rotate synchronously.

[0042] In other embodiments of the present application, a plurality of tobacco sorting systems may be arranged side by side along the second direction, so that the plurality of tobacco sorting systems can share a set of unloading and conveying mechanisms 32 .

[0043] While working: Piles of tobacco leaves 400 are deposited into the first accumulation area 113 at the entrance of the first sorting assembly 11. The first conveying mechanism 111 carries the tobacco leaves 400 forward, while the inclined first sorting mechanism 112 above it moves in the opposite direction along a circular path, contacting the top of the pile of tobacco leaves 400 and initially separating them layer by layer, forming a pile of tobacco leaves 400 with a first degree of dispersion. The pile is then discharged from the outlet of the sorting channel 114.

[0044] After initial separation, the tobacco leaves 400 enter the second accumulation area 124 at the bottom of the second sorting assembly 12. Multiple carriers 122 with sharp points 1221 on the second sorting base 121 move upward, driven by a synchronous belt. These sharp points 1221 pierce individual tobacco leaves 400, lifting them upward and ensuring that the tobacco leaves 400 enter the grading section 2 in a state of separation, or the second degree of discreteness.

[0045] The grading unit 2 scans the tobacco leaves 400 conveyed in a single piece and determines the grade based on its flat size and other characteristics.

[0046] After being graded, the tobacco leaves 400 are conveyed to the sorting and unloading section 3. This section comprises multiple sorting mechanisms 31 connected in series, each corresponding to a grade of tobacco leaves 400. Below each of these mechanisms, corresponding unloading conveyors 321 are arranged vertically. When tobacco leaves 400 reach a sorting mechanism 31 corresponding to a grade, the mechanism 31 swings downward about its horizontal axis, forming a sorting channel connecting it to the adjacent mechanism and the unloading conveyor 321 below. Through this channel, the tobacco leaves 400 fall onto the unloading conveyor 321 of the corresponding grade, separating and collecting tobacco leaves 400 of different grades. Multiple systems can be arranged side by side, with their unloading conveyors 321 operating in series.

[0047] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with this technology to understand the content of the present invention and implement it accordingly, and they are not intended to limit the scope of protection of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes that fall within the meaning and scope of the equivalent elements of the claims are included in the present invention.
