Description

Technical field: The invention relates to a device for layered output of first-cured tobacco leaves, in particular to a device for identifying the layering grades of first-cured tobacco leaves and a working method thereof. Background technology: At present, the quality of newly cured tobacco leaves needs to be differentiated. The traditional differentiation method is done manually, which has low efficiency and large workload.

[0003] In order to improve the efficiency of differentiation, the Chinese patent "Method and system for tobacco leaf grade identification based on MHHO algorithm and SVM model" publication number CN114266931A was retrieved. The tobacco leaf grade identification method and system are based on the MHHO algorithm and SVM model. The method includes obtaining a tobacco leaf grade chemical composition data set, training an initial SVM model in combination with the MHHO algorithm, and obtaining an optimized SVM model; obtaining a tobacco leaf grade chemical composition data set to be classified; inputting the data set into the optimized SVM model; determining the tobacco leaf grade and classifying it according to the output result of the SVM model; the SVM model optimization is specifically to optimize the SVM model selection parameters through the MHHO algorithm to achieve the optimized SVM model; the MHHO algorithm is: using a nonlinear time-varying strategy of chaotic perturbation convergence to update the Harris Hawk algorithm to explore the calculation strategy of escape energy in the conversion to the development stage; using a nonlinear time-varying strategy of chaotic perturbation convergence to update the position change strategy in the development stage of the Harris Hawk algorithm. This method can reduce data errors and effectively improve the efficiency and accuracy of tobacco leaf grade identification; but it does not have a specific device for realizing the layered output of piled tobacco leaves.

[0004] In addition, in order to realize that the material storage box is in two different working positions, a single air cylinder or hydraulic cylinder can be used. However, if three working positions are to be realized, the air cylinder or hydraulic cylinder cannot meet the use requirements, that is, only an electric push cylinder can be used. However, since the axial length of the electric push cylinder is relatively large, there may be movement interference with other components.

[0005] At present, a double-cylinder three-station suction cup transport device has been retrieved, which includes a base, a first sliding cylinder, a second sliding cylinder and a telescopic cylinder. The first sliding cylinder is fixed to the upper surface of the base, and the outer surface of the first sliding cylinder is sleeved with a first sliding seat. The upper surface of the first sliding seat is fixed with a first support platform by bolts, and the upper surface of the first support platform is fixed with a second sliding cylinder. The outer surface of the second sliding cylinder is sleeved with a second sliding seat and a buffer mechanism. The buffer mechanism includes a fixed sleeve, and the bottom end of the fixed sleeve is connected and fixed to the upper surface of the first support platform by screws. A buffer pile and a spring are arranged inside the fixed sleeve. The buffer pile is sleeved on the outer surface of the slide rail, and the buffer pile is telescopically connected to the fixed sleeve.

[0031] The first lifting mechanism A3 may be a lifting cylinder, an electric push cylinder, etc. The first lifting mechanism A3 of the present application specifically includes a first outer shell A26 (the first outer shell A26 covers the entire periphery of the first lifting mechanism, and most of the components of the first outer shell are omitted in the figure for ease of display), a servo motor A27 fixed to the upper part of the first outer shell, and a synchronous belt mechanism A28 provided on the output end of the servo motor. The belt of the synchronous belt mechanism is fixedly connected to an upper plate A29, and two pulleys of the synchronous belt mechanism are respectively provided on the upper and lower parts of the first outer shell (when the servo motor is working, the belt of the synchronous belt mechanism is driven to circulate, thereby driving the upper plate A29 to rise and fall in the first outer shell). The two sides of the upper plate A29 are fixedly connected with a first guide rod A30, the lower end of the first guide rod A30 passes through the lower part of the first outer shell and is fixedly connected to the lower plate A31, and the lower surface of the lower plate A31 is connected to the upper surface of the suction cup main beam A15 through a plurality of springs A32. The springs A32 can play a buffering role to avoid large force pressure damage to tobacco leaves.

[0032] The suction cup mechanism A2 includes a suction cup main beam A15 and multiple groups of parallel suction cup branches A16 vertically fixed below the suction cup main beam (both the suction cup main beam A15 and the suction cup branch A16 can be thin shells made of stainless steel), a plurality of strip-shaped suction cup air inlet grooves A17 are arranged on the lower surface of the suction cup branch A16 (a 1 cm thick sponge buffer can be attached to the suction cup air inlet groove to reduce the damage of the suction cup to the tobacco leaves during operation), the suction cup air inlet groove A17 is connected to the suction cup branch A16 and the negative pressure cavity in the suction cup main beam A15, and a suction cup air outlet A25 connected to the negative pressure mechanism A18 is provided on the suction cup main beam. Under the action of the negative pressure mechanism, the suction cup air inlet groove A17 of the suction cup branch A16 generates negative pressure for adsorbing tobacco leaves.

[0033] The specific negative pressure mechanism A18 includes an air pump A19 arranged in the lower part of the machine body, a main air duct A20 connected to the inlet end of the air pump, and an air outlet A21 connected to the outlet end of the air pump.

The inlet end of the main air duct is connected to the suction cup outlet A25 on the suction cup main beam A15 through a pipeline.

[0034] During operation, the air pump A19 works continuously, and the opening and closing states of the two butterfly valves (the main air duct butterfly valve A23 and the side air duct butterfly valve A24) are mutually exclusive (i.e. opposite). When the main air duct butterfly valve is opened and the side air duct butterfly valve is closed, negative pressure is generated in the main air duct and the suction cup air inlet slot A17, i.e. the suction cup generates negative pressure to absorb tobacco leaves; conversely, when the main air duct butterfly valve is closed and the side air duct butterfly valve is opened, negative pressure is generated in the side air duct, and there is no negative pressure at the suction cup air inlet slot A17, i.e. the suction cup does not generate negative pressure, and the suction cup unloads tobacco leaves. This structure can repeatedly generate negative pressure on the suction cup air inlet slot A17 of the suction cup mechanism, and at the same time can avoid the problem of repeated opening and closing of the air pump A19 causing easy damage and insufficient negative pressure.

The leaf guard rod is in a folding and unfolding position under the action of the first driving mechanism. When in the folding position, the leaf guard rod A7 is in contact with the adsorption lower surface of the suction cup mechanism A2 (that is, the suction cup air inlet slot A17 is located). When the adsorption mechanism is in the horizontal and vertical positions, the leaf guard rod is repeatedly swung and rotated in the horizontal and vertical positions. When the adsorption mechanism is adsorbing tobacco leaves, some tobacco leaves may fall easily due to insufficient adsorption area and insufficient adsorption force. Then, when the leaf guard rod is swung and rotated to the horizontal position, the leaf guard rod supports the tobacco leaves adsorbed by the adsorption mechanism. When the adsorption mechanism needs to be lifted or lowered (mainly downward to adsorb tobacco leaves), the leaf guard rod is swung and rotated to the vertical position to avoid the lifting and lowering of the adsorption mechanism.

[0036] The main frame A5 of the leaf guard mechanism includes a main beam A9 fixedly mounted on the machine body and a cantilever rod A10 vertically connected to both ends of the main beam. The leaf guard rod rotation axis A6 has two parallel to the main beam A9, one of which is close to the main beam A9 and the other is close to the free end of the cantilever rod (i.e., away from the main beam A9). Both ends of the leaf guard rod rotation axis A6 are rotatably connected to the cantilever rod A10. Two corresponding rotation axes are fixed on the inner side of a cantilever rod. A leaf guard rod driving cylinder A11 is arranged on the back (the first driving mechanism A8 is the leaf guard rod driving cylinder A11), and the free ends of the telescopic rods of the leaf guard rod driving cylinder A11 are connected to the leaf guard rod rotating shaft A6 through a swing arm A12. Under the action of the leaf guard rod driving cylinder A11, the two leaf guard rod rotating shafts A6 and the leaf guard rod A7 are relatively swung (that is, the leaf guard rod A7 rotates around the axis of the leaf guard rod rotating shaft A6), thereby realizing the switching of the leaf guard rod A7 between the horizontal work station and the vertical work station.

The two convex pins A14 are located on both sides of the swing arm to limit its swing angle. Under the action of the telescopic rod of the leaf guard rod driving cylinder A11, the cantilever rod A10 and the leaf guard rod rotating shaft A6 are rotated, and the leaf guard rod A7 can be limited to move within the horizontal and vertical positions through the limiting of the two convex pins A14.

A film sealing drive plate D3 is slidably connected to the vertical guide rail D2 (the film sealing drive plate D3 can slide vertically on the vertical guide rail D2), and the film sealing drive plate D3 is driven to rise and fall by a third lifting drive mechanism D4 fixed on the vertical plate (the third lifting drive mechanism D4 can be an electric push cylinder or a cylinder, etc.), a penetration groove D5 is provided in the middle of the bottom plate B8 (the penetration groove is arranged at the bottom of the rear inspection box body B4), and mounting frames D6 and film sealing brackets D7 rotatably connected to the mounting frames are provided on both sides of the penetration groove D5, and a film sealing reel D8 and a film sealing kit D9 (which is the existing technology, including Heating wire, bakelite and high-temperature cloth, etc., to heat-fuse the film), a film sealing frame transmission shaft D10 is connected to the length direction of the film sealing frame D7, and the film sealing frame transmission shaft D10 is connected to the film sealing drive plate D3 through the film sealing frame power rocker arm D11. When the third lifting drive mechanism drives the film sealing drive plate D3 to rise and fall, the film sealing frame power rocker arm D11 and the film sealing frame transmission shaft D10 drive the film sealing frame D7 to swing and cover the penetration groove D5, otherwise the penetration groove D5 is opened; when working, when the aforementioned suction cup mechanism puts the tobacco leaves detected and identified into the post-inspection box several times, the tobacco leaves in the post-inspection box can be packaged. When packaging, the third lifting drive mechanism drives the film sealing drive plate D12 to move, thereby driving the film sealing frame transmission shaft D10 and the film sealing frame D7 to swing, so that the two film sealing kits D9 are brought together, and after gathering, the electric heating wire film sealing and film cutting are started to realize the packaging action.

[0043] The box B2 includes a box to be inspected B3 and a box after inspection B4, between which there is a middle partition B21 for accommodating a mounting frame and a film sealing bracket on one side, and the side wall panels of the box after inspection B4 are provided with notches B41 for avoiding the swing of the film sealing bracket D7.

[0044] In order to flatten and compact the tobacco leaves in the inspection box B4 during packaging, a tobacco leaf compacting mechanism C is provided on the machine body, and the tobacco leaf compacting mechanism includes a second lifting mechanism C1 (the second lifting mechanism can be a cylinder, an electric push cylinder, etc.) and two outer fixed pressing plates C2 fixedly connected to the lower end of the telescopic rod of the second lifting mechanism and spaced apart, and the inner sides of the two outer fixed pressing plates are rotatably connected with a middle flip pressing plate C3 that can be opened and is located between the two outer fixed pressing plates.

[0045] The second lifting mechanism C1 includes a second outer shell (in order to facilitate viewing of the internal structure, the second outer shell is omitted in the figure, and the second lifting mechanism C1 and the second outer shell are fixed on the machine body) and a fixed cylinder C5 arranged in the second outer shell, the telescopic rod of the fixed cylinder passes downward through the second outer shell C4 and is fixedly connected to the lower cross plate C6, and second guide rods C7 that slide with the guide sleeves on the second outer shell are provided on both sides of the lower cross plate C6; side frames C8 are fixedly provided below the two side parts of the lower cross plate (the outer fixed pressure plate C2 is fixed to the lower part of the side frame C8), and the side frames C8 are respectively connected to the pressure plate flipping cylinders C9, and the free end of the telescopic rod of the pressure plate flipping cylinder is rotatably connected to the middle part of the middle flipping pressure plate C3, so that the middle flipping pressure plate C3 can be in a position flush with the outer fixed pressure plate C2 or a position perpendicular to the outer fixed pressure plate C2 under the drive of the pressure plate flipping cylinder C9.

[0046] The swinging area of ​​the film sealing bracket D7 is opposite to the flipping area of ​​the middle flipping plate C3, so that the middle flipping plate C3 flips up during film sealing. The middle flipping plate C3 not only flattens and tightens the middle position of the tobacco leaves in the box after inspection, but also effectively avoids the flipping action of the film sealing bracket D7.

[0047] In order to realize the output of packaged tobacco leaves, a discharge mechanism E is provided on the machine body, which includes a base plate B8 and a discharge plate E1 which is flipped and connected to the penetration groove E5 of the base plate, wherein the first side of the discharge plate is fixedly connected to the discharge shaft E2, and the discharge shaft E2 is rotatably connected to the bearing seat E3 of the base plate, and a curved discharge shaft driving arm E4 (the discharge shaft driving arm E4 is specifically L-shaped) is fixedly connected to the discharge shaft E2, and a fourth lifting mechanism E5 is fixedly connected to the base plate, and the free end of the telescopic rod of the fourth lifting mechanism is rotatably connected to the free end of the discharge shaft driving arm E4, so that when the fourth lifting mechanism E5 drives the telescopic rod to extend and retract, the discharge plate is driven to cover and open the penetration groove, so that the discharge plate can be received when it is covered, and when the penetration groove is opened, the packaged tobacco leaves fall through the penetration groove and are output.

[0048] A chamber for receiving the packaged tobacco leaves is provided at the lower part of the machine body, and the packaged tobacco leaves can be taken out from the chamber after all the tobacco leaves are packaged.

[0049] In order to make the closing of the unloading plate more stable, a corner cylinder E6 and a corner cylinder rotating arm E7 driven by the corner cylinder are provided on the second side of the penetration groove. The corner cylinder rotating arm E7 supports the second side of the unloading plate E1 when it swings (the corner cylinder rotating arm E7 avoids the opening of the unloading plate E1 when it swings in the opposite direction). When the unloading plate E1 is closed, it is supported by the corner cylinder rotating arm E7, so that the closing of the unloading plate E1 is more stable and reliable, and even the downward pressing action of the tobacco leaf pressing mechanism C can ensure the closing of the unloading plate E1.

[0050] The original image of the tobacco leaves and the corresponding grade information obtained through the layered recognition process of the camera are accessed in real time by the active device in the equipment. After the whole bundle of tobacco leaves is layered and absorbed and the grade recognition is completed, the monitoring system gives the comprehensive grade evaluation result of the whole bundle of tobacco leaves according to the preset comprehensive grade evaluation method. The evaluation result can be displayed on the human-computer interactive touch screen of the equipment, and a QR code bar can be automatically printed and generated (the QR code bar can be affixed to the packaged tobacco leaves) for subsequent scanning and query of the recognition results. The data and test results of each test process are uploaded to the remote server after the workflow is completed for subsequent comprehensive traceability query and analysis and evaluation (this content is existing technology and will not be described in detail here).

[0051] The working method of the device for identifying the stratified grade of freshly-cured tobacco leaves of the present invention is as follows: initially, the box is located at the first station, at which time the freshly-cured tobacco leaves to be inspected are placed in the box to be inspected, then the nested cylinder module is actuated to place the box at the second station, at which time the camera detects the freshly-cured tobacco leaves on the surface of the box to be inspected, and then the nested cylinder module is actuated to place the box at the third station, at which time the suction cup mechanism absorbs the freshly-cured tobacco leaves on the surface of the box to be inspected, then the outer linkage cylinder and the inner cylinder return to the second station, the suction cup mechanism puts the freshly-cured tobacco leaves absorbed at the third station into the box after inspection, and the detection camera in the machine body detects the freshly-cured tobacco leaves on the surface of the box to be inspected again, and this cycle is repeated several times, and when the freshly-cured tobacco leaves in the box after inspection reach a certain amount, the nested cylinder module is actuated to place the box at the third station, The tobacco leaf pressing mechanism starts to move, so that the outer fixed pressure plate presses and flattens the two ends of the freshly cured tobacco leaves, and at the same time, the middle flip pressure plate flips and presses and flattens the middle part of the freshly cured tobacco leaves, and then the middle flip pressure plate flips up to avoid the flipping of the sealing film bracket. The flipping of the sealing film brackets on both sides makes the sealing film kit approach and heat-fuse the sealing film output by the roll, and the sealing film is wrapped around the periphery of the freshly cured tobacco leaves in the inspection box. Finally, the fourth lifting mechanism is activated, so that the unloading plate is flipped open to open the penetration groove, and the freshly cured tobacco leaves in the inspection box fall due to gravity to complete the wrapping and output of a stack of freshly cured tobacco leaves, and then the unloading plate returns to close the penetration groove. At this time, the tobacco leaf pressing mechanism moves again so that the sealing film output by the roll by the outer fixed pressure plate can be flattened in the inspection box, so that the tobacco leaves subsequently placed in the inspection box are located on the sealing film.
