Intelligent tobacco harvesting method and system for large-leaf crops

Abstract

This invention relates to a smart tobacco harvesting method and system for large-leaf crops. The system includes a curing barn area, a re-humidification and drying barn, a sorting workshop, and a temporary industrial tobacco storage area. A new re-humidification area is constructed for more unified management of tobacco leaf re-humidification. AGVs and material racks are used for tobacco leaf transfer. The tobacco harvesting and sorting area uses automated equipment such as automatic feeding tobacco clips combined with intelligent sorting equipment and belt conveyor systems to achieve automatic clip disassembly, automatic feeding, sorting, and collection of tobacco leaves. This reduces manpower consumption during the tobacco harvesting period, lowers the workload of personnel, and improves the efficiency of the entire process. It can be implemented in one area. This system enables tobacco farmers to handle tobacco curing, rehumidification, sorting, and collection without having to manually unpack the tobacco leaves or transport them back and forth. It achieves one-stop tobacco collection. Furthermore, the automated equipment for transporting tobacco leaves, automatic feeding, and automatic sorting, along with the direct feeding of tobacco leaves after rehumidification in the curing barn, reduces the workload for farmers in disassembling, transferring, and initially sorting tobacco leaves, thus improving efficiency and reducing manpower consumption. This optimized traditional tobacco collection process reduces labor costs and workload, and enhances overall efficiency, helping tobacco farmers and tobacco stations achieve one-stop tobacco delivery and collection.

Description

Technical Field

[0001] This invention relates to the field of visual inspection technology, and in particular to a smart method and system for harvesting tobacco from large-leaf crops. Background Technology

[0002] The existing tobacco collection methods and procedures are as follows: Tobacco farmers deliver tobacco leaves to the curing barn, where they load the tobacco leaves into comb-type tobacco clips and send them into the curing barn for curing; after curing, the tobacco leaves are manually unpacked and transported back to their homes for re-moistening and initial sorting; then, they schedule delivery to the tobacco station and transport the tobacco leaves there; the tobacco station grades and classifies the tobacco leaves, usually through grading personnel or sorting equipment; after the testing, the results are publicized to the tobacco farmers; the tobacco farmers confirm whether to deliver the tobacco, and if they do, the tobacco leaves are settled and put into storage; if they do not deliver, the tobacco station returns the tobacco leaves to the tobacco farmers.

[0003] The main drawbacks and problems of the existing tobacco collection methods and processes are as follows: Tobacco farmers need to disassemble the tobacco clips themselves, transport the tobacco leaves back for rehydration and initial sorting, and then transport them to the tobacco station for delivery. The process is complex and the workload is large. Tobacco farmers need to disassemble the tobacco clips themselves or hire workers to rehydrate and initially sort the tobacco leaves, and they need to transfer the tobacco leaves back and forth. Tobacco stations use graders to inspect the tobacco, which relies heavily on professional personnel and has low capacity. When tobacco stations use sorting equipment for inspection, the current equipment bottleneck is manual loading of tobacco. Manual actions are numerous, inefficient, and labor-intensive, and the consistency of loading is low. Summary of the Invention

[0005] The technical solution adopted by this invention to solve its technical problem is: a smart method for harvesting tobacco from large-leaf crops, comprising the following steps:

[0006] S1. Tobacco farmers make appointments with the system to cure and deliver tobacco, and the system enters the tobacco farmers' identity information;

[0007] S2. The system assigns tobacco farmers corresponding curing barn areas, re-humidification areas, sorting production lines, and tobacco delivery times based on their identity information.

[0008] S3. During the tobacco delivery time, tobacco farmers transport tobacco leaves to the curing area and load fresh tobacco leaves onto comb-type tobacco clips; then the tobacco clips are placed into the assigned curing room for curing.

[0009] S4. After the curing is completed, the tobacco leaves are transported to the designated re-moistening area for re-moistening.

[0010] S5. After the re-dampening period ends, a message can be sent to notify tobacco farmers to collect their tobacco.

[0011] S6. Manually load the rehydrated tobacco leaves into the tobacco clip rack in the tobacco clip loading area, and transport the tobacco clip rack to the temporary storage area of ​​the tobacco clip trolley.

[0012] S7, AGV transports the material rack to the assigned sorting production line;

[0013] S8. The sorting production line automatically unclamps, feeds, and sorts the tobacco leaves. The sorted tobacco leaves are then collected into tobacco baskets by a belt conveyor.

[0014] S9, AGV / manual transport the sorted tobacco leaves to the weighing area for weighing, and post the grade and weight;

[0015] S10. The tobacco farmer decides whether to deliver the tobacco based on the information. If the farmer does not deliver the tobacco, the tobacco leaves are returned to the farmer. If the farmer delivers the tobacco, the purchased tobacco leaves are transferred to the hydraulic basket area after the settlement fee is entered into the system.

[0016] S11. The purchased tobacco leaves are manually collected into iron frames according to their grade. Then, a hydraulic truck is used to compact the tobacco leaves in the iron frames. Once the weight of the tobacco leaves in the iron frames meets the standard, a forklift is used to transfer the tobacco leaves in the iron frames to the temporary industrial tobacco warehouse for stacking and storage.

[0018] S71. Workers in the humid area fill the empty material racks and transport them to the material rack exit position, and input the storage position information into the PDA;

[0019] S72. If there is a shortage of material in the sorting production line, a button call will be made to generate a material feeding request.

[0020] S73. The scheduling system receives instructions and assigns AGVs to execute them.

[0021] S74 and AGV proceed to the production line section to return the empty material rack to the empty storage space in the rehumidification area;

[0022] S75 and AGV lower the empty material rack to the outbound position and transport the full material rack away.

[0066] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0067] like Figures 1-3The system described is a smart tobacco harvesting method and system for large-leaf crops. The entire system consists of a curing barn area, a rehumidification and drying barn, a sorting workshop, and a temporary industrial tobacco storage area. The curing barn area is equipped with multiple curing barns to process fresh tobacco leaves. The rehumidification and drying barn is divided into two main areas: Area A and Area B. Each area is further subdivided into a tobacco leaf rehumidification area, a tobacco clamp loading area, and a tobacco clamp trolley temporary storage area. Cured tobacco leaves are rehumidified in the rehumidification area, and the rehumidified leaves are loaded into tobacco clamp racks in the tobacco clamp loading area. Fully loaded racks are temporarily stored in the tobacco clamp trolley temporary storage area. The sorting workshop includes sorting line A, sorting line B, a weighing area, and a basket-combining hydraulic area. Sorting lines A and B automatically unclamp and automatically load the rehumidified tobacco leaves from Areas A and B of the rehumidification and drying barn, respectively. The process involves automatic sorting. After sorting, the tobacco leaves are collected by a conveyor belt and placed into tobacco baskets. In sorting line A, the tobacco baskets are manually placed onto pallets and then transported to the weighing area by AGV. In sorting line B, the tobacco leaves are directly transported to the weighing area by manual labor. The weighing area weighs the tobacco leaves and displays their grade and weight. Based on this information, tobacco farmers decide whether to deliver the tobacco. If they do not deliver, the tobacco leaves are returned to them. If they do deliver, after settling the payment, the purchased tobacco leaves are transferred to the hydraulic basket consolidation area. In the hydraulic basket consolidation area, there are four sets of consolidation frames, each corresponding to one of the four grades of tobacco leaves. The purchased tobacco leaves are manually consolidated into the frames according to their grade. Then, a hydraulic truck compacts the tobacco leaves in the frames. Once the weight of the tobacco leaves in the frames meets the standard, a forklift transfers the tobacco leaves in the frames to the temporary industrial tobacco warehouse for stacking and storage.

[0068] The specific tobacco collection process is as follows: Tobacco farmers reserve tobacco for curing and delivery to the system, and the system enters the farmers' identity information; the system assigns the corresponding curing barn area, rehydration area, sorting production line, and delivery time to the farmers based on their identity information; at the delivery time, the farmers transport the tobacco leaves to the curing area and load the fresh tobacco leaves onto the comb-type tobacco clips; then, the tobacco clips are placed in the assigned curing barn for curing; after curing, the tobacco leaves are transported to the assigned rehydration area for rehydration; after rehydration, a message can be sent to notify the farmers to collect the tobacco; workers manually load the rehydrated tobacco leaves into the tobacco clip racks in the tobacco clip loading area and transport the tobacco clip racks to the temporary storage area for the tobacco clip carts; AGVs transport the racks to the assigned sorting production line (the AGV scheduling process is as follows: workers in the rehydration area fill the empty racks and transport them to the rack exit position, and input the location information into the PDA; if the sorting production line is short of material, a button is pressed to generate a delivery request; the scheduling system receives the instruction and assigns the task). The AGV performs the operation; the AGV moves to the production line section and returns the empty material rack to the empty storage location in the rehydration area; the AGV lowers the empty material rack and moves to the outgoing location to transport the full material rack away; the AGV transports the full material rack to the empty storage location on the production line, completing this task; the sorting production line automatically unclamps, automatically feeds, and automatically sorts the tobacco leaves, and the sorted tobacco leaves are collected into tobacco baskets by a conveyor belt; the AGV / manual transport of the sorted tobacco leaves to the weighing area for weighing, and the grade and weight are displayed; the tobacco farmers then use the information... A decision is made regarding whether to deliver the tobacco. If not, the tobacco leaves are returned to the tobacco farmers. If they are delivered, after the settlement fee is entered into the system, the purchased tobacco leaves are transferred to the hydraulic crating area. In the hydraulic crating area, there are four sets of iron crates for packing, each corresponding to one of the four grades of tobacco leaves. The purchased tobacco leaves are manually packed into the iron crates according to their grade. Then, a hydraulic truck compacts the tobacco leaves in the iron crates. Once the weight of the tobacco leaves in the iron crates reaches the standard, a forklift is used to transfer the tobacco leaves in the iron crates to the temporary industrial tobacco leaf warehouse for stacking and storage.

[0069] like Figure 4-1 The automatic feeding device 100 for large-leaf crops shown is used in conjunction with the intelligent tobacco leaf sorting device 200, such as... Figure 4-12 As shown, this method reduces manual labor by changing the manual task of feeding large-leaf crops to directly feeding tobacco clips. This simplifies the process, significantly reduces the frequency of actions, and optimizes labor efficiency from 2 people per machine to 0.5 people per machine. The material input uses standard tobacco clips 5 (containing tobacco). The equipment buffers and unclamps the standard tobacco clips, then transfers the large-leaf crops 6 to a self-made clamp. The self-made clamp is then moved and sorted, thus separating the large-leaf crops (from one clip of tobacco into 3-5 pieces). The sorted large-leaf crops are then automatically fed into the large-leaf crop sorting equipment.

[0070] Specifically, it includes an automatic tobacco clip feeding device 1 and an automatic tobacco leaf sorting device 2; it also includes a recycling conveyor 3 and a recycling box 4; the recycling conveyor and recycling box are located below the automatic tobacco clip feeding device and the automatic tobacco leaf sorting device.

The cigarette clip is conveyed on the floating guide wheel module via the pulley module. A blocking cylinder 113 is provided at the end of the guide wheel module, and the cigarette clip is stopped at a preset position by the blocking cylinder. The floating guide wheel module can accommodate cigarette clips of different thicknesses. When the cigarette clip is conveyed to the position of the blocking cylinder, it is sensed by a proximity switch located near the position of the blocking cylinder. Then the blocking cylinder extends, and the blocking bar or blocking component keeps the cigarette clip in the preset position so that the two ends of the cigarette clip can be clamped subsequently.

[0073] The cigarette clip lifting mechanism 12 includes a lifting cylinder assembly 121; the lifting end of the lifting cylinder assembly is provided with a mounting plate 122; the mounting plate is provided with a feeding cylinder assembly 123; the extended end of the feeding cylinder assembly is provided with a clamping cylinder assembly 124 and a cigarette clip unlocking cylinder assembly 125; when the clamping cylinder assembly is activated, it clamps both ends of the cigarette clip, and the pressure head of the cigarette clip unlocking assembly extends to press the latch of the cigarette clip.

[0077] like Figure 4-6As shown, the passive unlocking module 23 includes a connecting plate 232 fixed to the frame via a support column 231; an unlocking guide strip 233 is provided at the bottom of the connecting plate; the unlocking guide strip is a wedge-shaped block.

[0078] like Figure 4-7 As shown, the fixture streamline module 22 includes a fixture streamline 221, a fixture return streamline 222, a first pusher module 223, a second pusher module 224, a third pusher module 225, a buffer synchronous belt module 226, a return synchronous belt module 227, a first carrier rotation module 228, a second carrier rotation module 229, and a pusher cylinder 2210; the buffer synchronous belt module has multiple fixtures buffered on it, and the first pusher module separates the multiple fixtures located on the buffer synchronous belt module one by one; the second pusher module and The third pushing module alternately pushes the jigs after order splitting to flow and load material on the jig flow line; the first carrier rotation module and the second carrier rotation module are respectively set at both ends of the jig flow line module; after loading, the empty jigs switch from the jig flow line to the jig return flow line through the first carrier rotation module; the return synchronous belt module transports the jigs on the return flow line to the second carrier rotation module; the second carrier rotation module switches the jig flow line again; the pushing cylinder pushes the jigs flowing through the second carrier rotation module to below the active unlocking module.

[0079] The first pushing module consists of a pushing motor A, a synchronous belt module A, and a one-way pushing device, among other components; the second pushing module consists of a pushing motor B, a synchronous belt module B, and a one-way pushing device, among other components; the third pushing module consists of a pushing motor C, a synchronous belt module C, and a one-way pushing device, among other components; and the pushing cylinder consists of a cylinder and a one-way pushing device, among other components.

[0080] like Figure 4-8 As shown, the fixture streamline / fixture return streamline includes a linear guide, and the first carrier rotation module and the second carrier rotation module are respectively disposed at both ends of the linear guide; the first carrier rotation module and the second carrier rotation module each include a rotary motor, and a rotary arm is connected to the rotation shaft of the rotary motor through a fixed plate; the fixture achieves streamline switching through the rotary arm.

[0081] like Figure 4-9As shown, the clamp 24 includes a clamp body 241, push blocks 242 are provided at both ends of the clamp body, and a slider 243 is provided at the bottom of the clamp body. The clamp body moves in the clamp streamline module through the push blocks and the slider. The clamp body is connected to clamp fingers 244. A clamp pressure plate 245 is provided at the bottom of the clamp fingers, and a foam strip 246 is provided on the clamp pressure plate. A second connecting rod 248 is provided in the middle of the clamp fingers, and the second connecting rod 248 is rotatably connected to the first connecting rod 247. A guide post 249 is provided at the center of the clamp body, and the clamp fingers are normally closed through a self-locking spring 2410 and the guide post.

The clamping flow and return line provides guidance and flow switching functions for the self-made clamps; the self-made clamps realize functions such as clamping large-leaf crops, and the self-made clamps are normally closed clamps, which can ensure that large-leaf crops are effectively clamped throughout the process, while eliminating unnecessary cables and enabling the circular flow and return of multiple sets of clamps; the pushing module A realizes the function of dividing the self-made clamps into orders, thereby realizing the division of large-leaf crops into bundles; the pushing modules B and C alternately push the self-made clamps after order division to flow on the flow line, thus realizing the function of feeding large-leaf crops together with the passive unlocking module; pushing... The cylinder pushes the self-made fixture from the return line to the flow line via the carrier rotating module B until the entire set of self-made fixtures is filled; after the large-leaf crop is changed, the buffer synchronous belt module pushes the entire set of self-made fixtures to the buffer position. After the material pushing module A divides a set of self-made fixtures into units, the buffer synchronous belt module continues to push the self-made fixtures to the units, and so on, until all self-made fixtures are divided into units; the return synchronous belt module uses the material feeding block to push the self-made fixture from the flow line to the return line via the carrier rotating module A in a step-by-step manner, and transports the self-made fixture to the carrier rotating module B.

[0085] The automatic tobacco clip feeding device performs actions such as disassembling tobacco clips, changing tobacco clips for large-leaf crops, and sorting large-leaf crops according to the characteristics of large-leaf crops being uniform in stem and loose in the tobacco clips.

[0086] Based on the characteristics of large-leaf crops being uniform in stem and loose in tobacco clamps, the automatic tobacco leaf sorting device uses a set of self-made clamps to hold the large-leaf crops in the tobacco clamps all at once. Then, through the pushing module A, the self-made clamps are separated one by one at the buffer position, thereby realizing the automatic sorting of large-leaf crops.

[0087] The entire feeding process is as follows:

[0088] The cigarette clips are manually loaded into the automatic feeding device for large-leaf crops. The cigarette clip conveying mechanism transports the cigarette clips to the preset position via a pulley module and a floating guide wheel module. The floating mechanism accommodates different thicknesses of cigarette clips through a floating device, enabling efficient conveying of different types of cigarette clips. A blocking cylinder is installed at the preset position, and a proximity switch is used to improve accuracy. When the cigarette clip reaches the preset position, the blocking cylinder extends to initially position the cigarette clip. Subsequently, the two ends of the cigarette clip are clamped by the clamping cylinder assembly. After the cigarette clip is clamped, it is pushed towards the disassembly position by the feeding cylinder assembly.

[0089] After the cigarette clip is conveyed to the disassembly position, the upper frame clamping block of the cigarette clip disassembly mechanism presses down and locks the inner side of the upper frame of the cigarette clip by the action of a cylinder, ensuring that the cigarette clip is well clamped in all directions. Then, the cigarette clip lifting mechanism lifts the cigarette clip to the replacement position. Below the active unlocking module, there is a set of self-made clamps that have returned to their positions. There are usually 32 clamps. Therefore, pressing down on the active unlocking module can open the set of self-made clamps, but at this time the cigarette clip is not disassembled, and the tobacco stems of the large-leaf crops in the cigarette clip are within the clamping range of the self-made clamps. The large-leaf crop dividing comb mechanism operates to divide the large-leaf crops in the cigarette clip into independent groups, minimizing the probability of stem overlap between groups. Subsequently, the active unlocking module retracts, allowing the self-made clamps to hold the tobacco stems. Then, the cigarette clip disassembly mechanism activates, the unlocking cylinder presses the cigarette clip's latch, and the locking structure between the upper and lower frames of the cigarette clip is released. Because the upper frame clamping block is pneumatically pressed down and latches onto the inside of the upper frame, the disassembly cylinder moves backward, pulling the upper frame of the cigarette clip open. Simultaneously, the lower frame of the cigarette clip retracts with the feeding cylinder, at which point the cigarette clip is disassembled. Subsequently, the large-leaf crops are transferred from the cigarette clip to the homemade clamp. The buffer synchronous belt module transports the entire homemade clamp set to the buffer position.

[0090] Afterwards, the tobacco clip disassembly mechanism closes the tobacco clips that no longer contain large-leaf crops again (the closing action of the tobacco clip is the opposite of the opening action of the tobacco clip, which will not be described here), and pushes the tobacco clips onto the belt conveyor mechanism; the belt conveyor mechanism returns the empty tobacco clips; after the empty tobacco clips are full, it reminds the personnel to pick up and put away the tobacco clips.

[0091] Meanwhile, the clamps in the buffer position are divided into individual clamps through the pusher module A, thus enabling the sorting of large-leaf crops. During sorting, the pusher motor A drives the unidirectional pusher through the synchronous belt module A to push the individual clamps forward to an intermediate position;

[0092] Then, pusher modules B and C alternately transport the pre-sorted, centrally located self-made clamps to carrier rotation module A through their respective module structures. During this process, the large-leaf crops in the self-made clamps are unlocked by the passive unlocking module and dropped into the intelligent large-leaf crop sorting equipment for sorting. Carrier rotation module A rotates the self-made clamps, which have completed the loading of large-leaf crops, 180° up and down to the clamp return line. The return synchronous belt module transports the self-made clamps to carrier rotation module B. Carrier rotation module B rotates the self-made clamps 180° up and down to the clamp flow line, and the pusher cylinder continuously pushes the self-made clamps to the clamp changing position until the entire set of clamps is in place. Once the entire set of clamps is in place, the next cycle can begin.

[0093] The above description is only a specific embodiment of the present invention. Various examples and illustrations do not constitute a limitation on the substantive content of the present invention. Those skilled in the art can make modifications or variations to the above-described specific embodiments after reading the specification without departing from the substance and scope of the invention.
