Description

Technical Field

[0001] The utility model relates to the technical field of classifying or arranging tobacco leaves, and particularly relates to an automatic rotary cycle grasping and grading device for tobacco leaves. Background Art

[0002] Flue-cured tobacco is a leaf economic crop. Due to various factors such as production conditions, production levels, and the position of leaves on the plant, the quality of the tobacco leaves produced by tobacco farmers varies greatly, from excellent to poor. The purpose of flue-cured tobacco grading is to embody the principle of pricing according to quality, classify the tobacco leaves according to their quality, divide them into different grades, and lay a foundation for tobacco leaf purchasing, meeting the needs of cigarette industrial formulations, and realizing the rational utilization of resources. At present, the grading of tobacco leaves mainly relies on manual grading. Grading personnel judge according to the "Flue-cured Tobacco" (GB 2635-1992) standard combined with personal experience and subjective consciousness, but this inevitably leads to inconsistent grading results. Even with clear standards, different grading personnel may have different evaluations of the same tobacco leaf. Moreover, the manual grading process requires a large amount of manpower and material resources, with high labor costs, low grading efficiency, difficult quality control, and great difficulty in supervising the grading process.

[0003] Although some automatic grading equipment has gradually been developed in the industry. For example, in the Chinese invention patent "A Tobacco Lean Selection Method and Its Selection System" (publication number CN106643523A), multiple groups of manual grading production lines are arranged on both sides of the tobacco leaf conveyor belt. Tobacco leaf graders grade the collected tobacco leaves, and the graded tobacco leaves are transferred to the tobacco leaf conveyor belt manually or by the conveyor belt. At the end of the tobacco leaf conveyor belt, a tobacco leaf grade identification conveyor belt is connected. An infrared detection device and a color recognition device are arranged on the tobacco leaf grade identification conveyor belt. The infrared detection device and the color recognition device transmit the detection parameters of the tobacco leaves on the conveyor belt to the grade determination server. The grade determination server compares the stored grade parameters with the measured parameters to obtain the tobacco leaf grade. At the same time, the grade determination server controls the conveyor belt to transfer tobacco leaves of different grades to different tobacco leaf grade loading baskets for loading. Thus, the efficiency can be improved and the grading accuracy can be increased. Another example is the Chinese utility model patent "A Cigar Tobacco Leaf Grading Device" (publication number CN221228713U), which includes a feeding belt conveyor, a photographing belt conveyor, a discharging belt conveyor, and multiple line body flap machines arranged in sequence. The photographing belt conveyor includes a cabinet and a cabinet conveyor belt. Through holes are arranged on both sides of the cabinet. The cabinet conveyor belt is horizontally arranged through the through holes. A lamp top frame is arranged in the cabinet in a liftable manner. The lamp top frame is located above the cabinet conveyor belt, and a strip lamp is arranged on the bottom surface of the lamp top frame. A camera for photographing the tobacco leaves on the cabinet conveyor belt is arranged on the lamp top frame. An alarm lamp is arranged on the top of the cabinet, and a display is arranged on one side of the cabinet. In existing automatic grading equipment, a belt conveyor type grading design is mostly adopted. The grading is carried out by putting tobacco leaves manually at the front end of the equipment plus the equipment, that is, manually putting tobacco leaves one by one onto the conveyor at the front, and grading the tobacco leaves through the special grading equipment at the back. Although this equipment avoids manual grading determination, it still requires a large amount of manpower to put tobacco leaves, has low production efficiency, a large overall volume of the equipment, occupies a large working site, has a high manufacturing cost, and is difficult to promote in the market.

[0029] In the description of the present utility model, it should also be noted that unless otherwise clearly specified and defined, the terms "set", "installed", "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0030] Such as Figures 1 to 4As shown in the figure, an automatic rotary cycle grasping and grading device for tobacco leaves provided by the present utility model includes a frame-type support 1. A platen 2 for carrying a main spindle box 4 is installed at the top of the support 1. The main spindle box 4 includes a box body, a main spindle, bearings, etc., which are common designs in the field. The lower end of the main spindle of the main spindle box 4 passes through the platen 2 and is connected to the output shaft of a servo motor 3 installed on the lower side of the support 1 through a coupling. The upper end of the main spindle of the main spindle box 4 is connected to a rotating disc 5. A multi-station cantilever 6 is installed on the rotating disc 5 as an integral structure. By rotating the main spindle of the main spindle box 4, the rotating disc 5 and the multi-station cantilever 6 are driven to rotate counterclockwise together, as Figure 4 shown.

[0031] In this embodiment, the multi-station cantilever 6 is an octagonal frame structure. To achieve multiple stations, a quadrilateral frame structure or a hexagonal frame structure can be adopted. Of course, a decagonal or dodecagonal structure can also be used, all of which are for the technical purpose of realizing multiple stations.

[0032] As Figure 1 and Figure 5 , Figure 6 shown, several integrated grasping mechanisms 7 capable of moving up and down are arranged on the side of the octagonal multi-station cantilever 6 away from the rotating disc 5. That is, a lifting cylinder 8 is installed at the center position of each side of the octagonal multi-station cantilever 6. A connecting plate 703 is horizontally installed at the telescopic rod end of the lifting cylinder 8. Integrated grippers 701 and suction cups 702 are arranged in pairs on the connecting plate 703. In this embodiment, 4 groups of integrated grippers 701 and suction cups 702 are arranged on each side of the octagonal multi-station cantilever 6. Through the design of physical integrated grippers 701 and air suction type suction cups 702, it is ensured that tobacco leaves can be effectively grasped. Of course, in this embodiment, the lifting cylinder 8 is used to drive the integrated grasping mechanism 7 to move up and down. A linear motor, an oil cylinder, etc. can also be used for replacement, which are all equivalent technical replacements. The integrated grippers 701 and suction cups 702 are existing equipment and can be directly purchased.

[0033] It further includes a camera image recognition table 9. The camera image recognition table 9 is arranged below the integrated grasping mechanism 7, that is, the camera image recognition table 9 is arranged at the next rotating station of the continuous tobacco leaf grading and feeding mechanism 100. Identifying the situation of tobacco leaves through a camera is a technology that has been adopted in the field. A camera with a vertically upward lens and a supplementary light are arranged on the camera image recognition table 9.

[0034] It further includes a light shield 10. The light shields 10 are installed on both sides of the gripping mechanism 7 integrated on the multi-station cantilever 6. In this embodiment, since there are 4 sets of integrated grippers 701 and suction cups 702 arranged on each side of the multi-station cantilever 6, 4 light shields 10 are provided. The light shields 10 are used to ensure that after the integrated gripping mechanism 7 descends to complete the gripping from the tobacco supply box of the continuous tobacco supply mechanism 100 for tobacco leaf grading and then ascends between the two light shields 10, during the process of taking pictures by the camera on the camera image recognition table 9, the side light is prevented from affecting the picture-taking effect, thereby improving the accuracy of recognition.

[0035] During operation, the servo motor 3 drives the main shaft of the headstock 4 to rotate, driving the rotating disc 5 and the multi-station cantilever 6 to rotate counterclockwise together. When any one of the stations rotates to the working position of the tobacco supply box of the continuous tobacco supply mechanism 100 for tobacco leaf grading, the lifting cylinder 8 drives the integrated gripping mechanism 7 to move downward. At this time, the integrated grippers 701 and suction cups 702 start to work. After gripping the tobacco leaves in the tobacco supply box, it continues to rotate to directly above the camera image recognition table 9. The camera image recognition table 9 starts to capture and extract the tobacco leaf pictures, and performs image recognition and analysis on each tobacco leaf on each gripper and suction cup in each group, so as to distinguish different tobacco leaves on each gripper and suction cup in each group. After that, it rotates to directly above the corresponding 11-way splitter box under the command control and is placed into the 11-way splitter box. Each station repeats this cycle to complete the grading work and perform the grading process. Of course, the tobacco leaves in the tobacco supply box of the continuous tobacco supply mechanism 100 for tobacco leaf grading should be placed in four rows to correspond to the 4 sets of integrated gripping mechanisms 7.

[0036] The present invention has been described in detail through specific and preferred embodiments above. However, those skilled in the art should understand that the present invention is not limited to the above-described embodiments. Any modifications, equivalent replacements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
