Description

Technical Field

[0001] This application relates to the field of tobacco technology, and more specifically, to a tobacco leaf slicing device. Background Technology

[0002] The production process of cigarettes generally includes initial curing of tobacco leaves, threshing and re-curing, tobacco fermentation, cigarette formulation, cigarette making, cigarette rolling, and cigarette packaging. Initial curing is the primary step in transforming cultivated tobacco leaves into cigarette raw materials. It involves placing harvested fresh tobacco leaves in a curing barn to dry and process them, turning them into the "raw tobacco" for cigarettes. After curing, the tobacco leaves undergo significant changes in their internal substances, appearance, and microstructure. The color changes from yellowish-green to yellow, and the moisture content changes from an expanded state of 80-90% to wilting, drying, and eventually charring. After initial curing, the wilted and dried tobacco leaves are usually bundled together for further processing. These bundled leaves require pre-treatment before production, such as separating the stacked or huddled leaves for subsequent processing. However, traditional tobacco leaf separation is done manually, which is inefficient and increases labor costs. Utility Model Content

[0024] Optionally, the above-mentioned tobacco leaf slicing device further includes a tobacco leaf sorting conveyor for receiving the tobacco leaf sorting conveyor on the discharge conveyor, a suction cup disposed above the sorting conveyor, and a mechanical arm for driving the movement of the suction cup. The suction cup is used to pick up and put down the tobacco leaves on the sorting conveyor to rearrange them.

Therefore, when they fall onto the primary conveyor, they no longer stack, thus achieving at least partial separation of the originally stacked tobacco leaves. Then, for the tobacco leaves still stacked on the primary conveyor, the primary vacuum adsorption conveyor line can pick up the upper layer of tobacco leaves. Because the speed of the primary vacuum adsorption conveyor line is greater than the speed of the primary conveyor, a travel difference occurs between the tobacco leaves adsorbed by the primary vacuum adsorption conveyor line and the tobacco leaves on the primary conveyor. Therefore, when they fall onto the discharge conveyor, they no longer stack, thus achieving further separation of the stacked tobacco leaves. Through this two-stage separation process, the stacked leaves can be effectively separated.

[0030] In summary, the tobacco leaf separating device provided in this application can realize the automatic separation of stacked tobacco leaves, which improves the efficiency and reduces the cost compared with traditional manual separation. Attached Figure Description

[0040] This application discloses a tobacco leaf slicing device to improve the tobacco leaf separation effect and reduce costs.

[0041] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0042] In some embodiments, please refer to Figures 1-4 The tobacco leaf slicing device provided in this application includes a differential speed separation conveyor line 1 and a robotic sorting system 2. The differential speed separation conveyor line 1 utilizes the speed difference between a conveyor and a vacuum adsorption conveyor line to separate stacked or clustered tobacco leaves. The robotic sorting system 2 uses a robotic arm 23 to drive a suction cup 22 to pick up the tobacco leaves and transfer them to other locations, thereby separating stacked or clustered tobacco leaves or achieving orderly arrangement of tobacco leaves. In some embodiments, the tobacco leaf slicing device may also include only the differential speed separation conveyor line 1 without the robotic sorting system 2, and can still achieve tobacco leaf separation.

[0043] In some embodiments, the tobacco leaf slicing device includes a differential speed separation conveyor line 1. The differential speed separation conveyor line 1 includes a primary conveyor 12, a primary vacuum adsorption conveyor line 13, a secondary conveyor 14, a secondary vacuum adsorption conveyor line 15, and a discharge conveyor 11. The discharge conveyor 11 supports the tobacco leaves and moves them from their inlet end to their outlet end for output. The primary conveyor 12 supports the tobacco leaves and moves them from their inlet end to their discharge end, and the discharge end of the primary conveyor 12 is located above the discharge conveyor 11 to discharge the tobacco leaves from the primary conveyor 12 to the discharge conveyor 11.

[0044] The secondary conveyor 14 is used to support the tobacco leaves and move them from the feed end to the discharge end. The discharge end of the secondary conveyor 14 is located above the feed end of the primary conveyor 12, so that the tobacco leaves on the secondary conveyor 14 are discharged onto the primary conveyor 12.

[0045] A primary vacuum adsorption conveyor line 13 is located above the primary conveyor 12 and is used to adsorb and convey tobacco leaves to its discharge end. The discharge end of the primary vacuum adsorption conveyor line 13 is located above the discharge conveyor 11 so that the tobacco leaves adsorbed on the primary vacuum adsorption conveyor line 13 are discharged to the discharge conveyor 11. For example, the discharge end of the primary vacuum adsorption conveyor line 13 is located above the middle of the discharge conveyor 11.

[0046] The secondary vacuum adsorption conveyor line 15 is located above the secondary conveyor 14 and is used to adsorb and convey tobacco leaves to its discharge end. The discharge end of the secondary vacuum adsorption conveyor line 15 is located above the primary conveyor 12 so that the tobacco leaves adsorbed on the secondary vacuum adsorption conveyor line 15 are discharged to the primary conveyor 12. For example, the discharge end of the secondary vacuum adsorption conveyor line 15 is located above the middle of the primary conveyor 12.

[0047] The speeds of the secondary conveyor 14, secondary vacuum adsorption conveyor 15, primary conveyor 12, and primary vacuum adsorption conveyor 13 increase sequentially, resulting in a speed of tobacco leaves on the secondary conveyor 14 < speed of tobacco leaves on the secondary vacuum adsorption conveyor 15 < speed of tobacco leaves on the primary conveyor 12 < speed of tobacco leaves on the primary vacuum adsorption conveyor 13. Since the speed of tobacco leaves on the secondary vacuum adsorption conveyor 15 is greater than that on the secondary conveyor 14, the secondary vacuum adsorption conveyor 15 adsorbs the upper layer of tobacco leaves stacked on the secondary conveyor 14 and moves them. Due to the difference in speed, a travel difference is created between the originally stacked tobacco leaves, meaning that when the tobacco leaves are fed to the primary conveyor 12, the upper layer of tobacco leaves adsorbed by the secondary vacuum adsorption conveyor 15 will fall in front of the original lower layer of tobacco leaves on the secondary conveyor, thus achieving separation. Similarly, since the speed of tobacco leaves on the primary vacuum adsorption conveyor 13 is greater than that on the primary conveyor 12, a travel difference is created between the originally stacked tobacco leaves, enabling separation when the tobacco leaves are fed to the discharge conveyor 11.

[0048] Using the tobacco leaf slicing device provided in this application, when tobacco leaves are stacked on the secondary conveyor 14, the secondary vacuum adsorption conveyor line 15 can pick up the upper layer of tobacco leaves. Since the speed of the secondary vacuum adsorption conveyor line 15 is greater than the speed of the secondary conveyor 14, a travel difference will occur between the tobacco leaves adsorbed by the secondary vacuum adsorption conveyor line 15 and the tobacco leaves on the secondary conveyor 14. Therefore, when they fall onto the primary conveyor 12, they will no longer be stacked, thus achieving at least partial separation of the originally stacked tobacco leaves. Then, for the tobacco leaves still stacked on the primary conveyor 12, the primary vacuum adsorption conveyor line 13 can further pick up the upper layer of tobacco leaves. Since the speed of the primary vacuum adsorption conveyor line 13 is greater than the speed of the primary conveyor 12, a travel difference will occur between the tobacco leaves adsorbed by the primary vacuum adsorption conveyor line 13 and the tobacco leaves on the primary conveyor 12. Therefore, when they fall onto the discharge conveyor 11, they will no longer be stacked, thus achieving further separation of the stacked tobacco leaves. Through the two-stage separation action, the stacked leaves can be effectively separated, realizing the spreading and thinning of the tobacco leaves.

[0049] In summary, the tobacco leaf separating device provided in this application can realize the automatic separation of stacked tobacco leaves, which improves the efficiency and reduces the cost compared with traditional manual separation.

[0050] In some embodiments, the differential speed separation conveyor line 1 further includes a three-stage conveyor 16 and a three-stage vacuum adsorption conveyor line 17. The discharge end of the three-stage conveyor 16 is located above the loading end of the two-stage conveyor 14. The three-stage vacuum adsorption conveyor line 17 is located above the three-stage conveyor 16 and is used to adsorb and convey tobacco leaves. The discharge end of the three-stage vacuum adsorption conveyor line 17 is located above the two-stage conveyor 14. For example, the discharge end of the three-stage vacuum adsorption conveyor line 17 is located above the middle of the two-stage conveyor 14. The speed of the three-stage conveyor 16 is less than the speed of the three-stage vacuum adsorption conveyor line 17, and the speed of the three-stage vacuum adsorption conveyor line 17 is less than the speed of the two-stage conveyor 14. In this embodiment, a first-stage differential speed separation, i.e., a three-stage differential speed separation, is added based on the above-mentioned two-stage differential speed separation. Because the speed of the tobacco leaves on the three-stage vacuum adsorption conveyor line 17 is greater than that on the three-stage conveyor 16, the three-stage vacuum adsorption conveyor line 17 adsorbs the upper layer of tobacco leaves stacked on the three-stage conveyor 16 and moves them. Due to the differential speed, a travel difference is created between the originally stacked tobacco leaves. That is, when the material is fed to the two-stage conveyor 14, the upper layer of tobacco leaves adsorbed by the three-stage vacuum adsorption conveyor line 17 will fall in front of the original lower layer of tobacco leaves on the three-stage conveyor line, thus achieving separation. The subsequent two-stage separation is the same as in the above embodiment, and will not be repeated here. By setting up a three-stage staggered conveyor line, the first two stages (the three-stage vacuum adsorption conveyor line 17 and the two-stage vacuum adsorption conveyor line 15) achieve differential speed reduction of the thickness of the stacked tobacco leaves, and the last stage (the one-stage vacuum adsorption conveyor line 13) achieves separation or small-scale aggregation between tobacco leaves, resulting in better tobacco leaf separation. For example, the above embodiment of three-stage differential speed separation is applicable to tobacco leaf stack thickness of 10 leaves or less, including 10 leaves. It is understandable that the above-described two-stage differential separation method is applicable to situations where the stacking thickness of tobacco leaves is smaller, such as 6 leaves or less.

[0051] In some embodiments, the primary vacuum adsorption conveyor line 13 is a primary vacuum adsorption belt conveyor. Vacuum adsorption belt conveyors have a simple structure and reliable adsorption. By opening adsorption holes on the conveyor belt and correspondingly setting negative pressure chambers, negative pressure is formed at the adsorption holes, thereby enabling the tobacco leaves to be drawn up. It is understood that a negative pressure chamber may not be provided at the discharge end of the primary vacuum adsorption conveyor line 13, allowing the tobacco leaves to fall under gravity after losing adsorption at the discharge end. Exemplarily, the secondary vacuum adsorption conveyor line 15 is a secondary vacuum adsorption belt conveyor, and the tertiary vacuum adsorption conveyor line 17 is a tertiary vacuum adsorption belt conveyor. The structures of the secondary and tertiary vacuum adsorption belt conveyors can refer to those of the primary vacuum adsorption belt conveyor, and will not be repeated here. In other embodiments, the primary vacuum adsorption conveyor line 13, the secondary vacuum adsorption conveyor line 15, and the tertiary vacuum adsorption conveyor line 17 may also employ other vacuum adsorption conveyor structures besides belt conveyors.

[0052] In some embodiments, the primary conveyor 12 is a primary belt conveyor line. Belt conveyor lines have a simple structure, convenient speed adjustment, and can effectively support tobacco leaves. For example, the secondary conveyor 14 is a secondary belt conveyor line; and the tertiary conveyor 16 is a tertiary belt conveyor line. In other embodiments, the primary conveyor 12, secondary conveyor 14, and tertiary conveyor 16 may also employ other conveyor structures besides belt conveyors.

[0053] In some embodiments, the differential speed separating conveyor line 1 further includes a mounting frame 18, which includes a first column 181 supported under the primary conveyor 12, a second column 182 supported under the secondary conveyor 14, a third column 183 supported under the tertiary conveyor 16, and a fourth column 184 supported under the discharge conveyor 11; wherein the heights of the fourth column 184, the first column 181, the second column 182, and the third column 183 increase sequentially. It is understood that the number of the first column 181, the second column 182, the third column 183, and the fourth column 184 can be set as needed, such as two or four respectively, to provide stable support. The mounting components facilitate the installation of each stage of the conveyor and the relocation of the overall differential speed separating conveyor line 1.

[0054] In some embodiments, the mounting frame 18 further includes multiple connectors respectively connected between the primary vacuum adsorption conveyor line 13, the secondary vacuum adsorption conveyor line 15, the tertiary vacuum adsorption conveyor line 17 and the corresponding primary conveyor 12, secondary conveyor 14, tertiary conveyor 16 and discharge conveyor 11 below. That is, the vacuum adsorption conveyor lines are mounted to the conveyors via corresponding connectors. For example, the connectors include a first connector 185, a second connector 186, a third connector 187, a fourth connector 188, and a fifth connector 189. The two ends of the first connector 185 are connected to the tertiary vacuum adsorption conveyor line 17 and the tertiary conveyor 16, respectively; the two ends of the second connector 186 are connected to the tertiary vacuum adsorption conveyor line 17 and the secondary conveyor 14, respectively; the two ends of the third connector 187 are connected to the secondary vacuum adsorption conveyor line 15 and the secondary conveyor 14, respectively; the two ends of the fourth connector 188 are connected to the secondary vacuum adsorption conveyor line 15 and the primary conveyor 12, respectively; and the two ends of the fifth connector 189 are connected to the primary vacuum adsorption conveyor line 13 and the output conveyor, respectively. The installation of the primary vacuum adsorption conveyor line 13, the secondary vacuum adsorption conveyor line 15, and the tertiary vacuum adsorption conveyor line 17 is achieved through the connectors, resulting in a simple structure and reliable installation.

[0055] In some embodiments, the robotic sorting system 2 includes a sorting conveyor 21 for receiving tobacco leaves from the discharge conveyor 11, a suction cup 22 disposed above the sorting conveyor 21, and a robotic arm 23 for driving the suction cup 22 to move. The suction cup 22 is used to pick up and release the tobacco leaves from the discharge conveyor 11 to rearrange them. The sorting conveyor 21 can specifically be a sorting belt conveyor, which can be part of the discharge conveyor 11 or another conveyor. For example, the sorting conveyor 21 is disposed below the unloading end of the discharge conveyor 11. The robotic arm 23 can move the suction cup 22 within space. The suction cup 22 can use vacuum adsorption to pick up the tobacco leaves from the sorting conveyor 21 and move it to a suitable position and angle to release it back onto the sorting conveyor 21. With the above arrangement, the leaves separated by the differential speed separation conveyor line 1 can be rearranged to arrange them in an orderly manner. When some leaves are stacked, the upper layer of leaves can also be separated and arranged in an orderly manner.

[0056] In some embodiments, the robotic arm 23 is a spider-hand robotic arm. The spider-hand robotic arm has a simple structure, high flexibility, and can move in confined spaces, thereby enabling precise and efficient movement of the blades.

[0057] In some embodiments, the robotic sorting system 2 further includes a camera 24 and a host computer 25. The camera 24 is used to acquire images of tobacco leaves above the sorting conveyor 21. The host computer 25 is connected to both the camera 24 and the robotic arm 23 to control the movement of the robotic arm 23 based on the images acquired by the camera 24. The robotic arm 23 is guided by vision, specifically a spider-like robotic arm, to separate small, clustered tobacco leaves using grasping or other methods, and to arrange the separated tobacco leaves in an orderly manner, resulting in the final orderly arrangement of individual tobacco leaves after sorting. For the specific control process and principles of the host computer 25 on the robotic arm 23 based on the images acquired by the camera 24, please refer to existing technologies; these will not be elaborated upon here.

[0058] In some embodiments, the robotic sorting system 2 further includes a frame 27, a robotic arm 23 mounted on the frame 27, a sorting conveyor 21 located within the frame 27, and casters at the bottom of the frame 27. The frame 27 is used to mount the robotic arm 23, and a suction cup 22 is located at the end of the robotic arm 23. The casters at the bottom of the frame 27 facilitate the overall movement of the robotic sorting system 2 to adjust its position relative to the sorting conveyor 21 or to remove the robotic sorting system 2 as needed. For example, a host computer 25 is mounted on the frame 27 and is used to control the tobacco leaf slicing device to operate according to a set configuration. In some embodiments, the robotic sorting system 2 further includes an electrical control system 26 mounted on the frame 27 for controlling the equipment to operate according to a set configuration.
