Description

Technical Field

[0001] This invention relates to the field of tobacco leaf re-drying technology, and in particular to a method, apparatus, equipment, medium, and product for leaf spreading and feeding. Background Technology

[0002] The leaf-laying and feeding effect in a re-drying plant is closely related to the tobacco leaf formula. Current leaf-laying and feeding methods utilize various feeding points on the leaf-laying conveyor line to feed different components of the tobacco leaf. A maximum of 16 feeding points can be deployed on the leaf-laying conveyor line, while tobacco leaves generally involve at least 10 components, and complex formulas may contain more than 24 or even 40 components. The higher the number of components in the tobacco leaf, the more leaf-laying cycles are required, the more component scheduling work is involved, and the higher the complexity and resource demand of the leaf-laying and feeding task. Furthermore, the demand for different components varies, and matching each component to a feeding point can easily lead to some feeding points being idle for extended periods, reducing the utilization rate of the feeding points on the leaf-laying conveyor line.

[0003] Therefore, proposing a simple, low-cost, intelligent, and efficient leaf-laying and feeding method to improve feeding efficiency and utilization rate of feeding points on the leaf-laying conveyor line, thereby enhancing the production smoothness and production effect of the re-drying plant, is an urgent problem to be solved in the tobacco re-drying field. Summary of the Invention

[0004] This invention provides a leaf-laying feeding method, apparatus, equipment, medium, and product, aiming to improve feeding efficiency and the utilization rate of feeding points on the leaf-laying conveyor line, thereby enhancing the production smoothness and production effect of the re-drying plant.

[0005] According to one aspect of the present invention, a leaf-laying feeding method is provided, the method comprising:

[0006] Obtain the formulation information of tobacco leaves, and determine the composition ratio of at least i tobacco leaf components and at least i tobacco leaf components based on the formulation information, where i is a positive integer greater than 10;

[0007] Determine the number of categories for at least i tobacco leaf components, and divide the at least i tobacco leaf components based on the number of categories and the composition ratio of the at least i tobacco leaf components to obtain at least one leaf laying task set, wherein the number of leaf laying task sets is the same as the number of categories;

[0008] Determine the leaf-laying conveyor line for each leaf-laying task set. Based on the leaf-laying conveyor line for each leaf-laying task set and the composition ratio of each tobacco leaf component material in each leaf-laying task set, determine the leaf-laying control information for each tobacco leaf component material in each leaf-laying task set, and execute the leaf-laying and feeding task for tobacco leaves based on the leaf-laying control information for each tobacco leaf component material in each leaf-laying task set.

[0009] According to another aspect of the present invention, a leaf-laying feeding device is provided, which is used to implement the leaf-laying feeding method in any embodiment of the present invention. The device includes:

[0010] The information acquisition module is used to acquire the formulation information of tobacco leaves and determine the composition ratio of at least i tobacco leaf components and at least i tobacco leaf components based on the formulation information, where i is a positive integer greater than 10.

[0011] The task determination module is used to determine the number of categories of at least i tobacco leaf components, and to divide the at least i tobacco leaf components based on the number of categories and the composition ratio of the at least i tobacco leaf components to obtain at least one leaf laying task set, wherein the number of leaf laying task sets is the same as the number of categories;

[0012] The leaf-laying execution module is used to determine the leaf-laying conveyor line for each leaf-laying task set, determine the leaf-laying control information for each tobacco component material in each leaf-laying task set based on the leaf-laying conveyor line and the composition ratio of each tobacco component material in each leaf-laying task set, and execute the leaf-laying and feeding task of tobacco based on the leaf-laying control information of each tobacco component material in each leaf-laying task set.

[0013] According to another aspect of the present invention, an electronic device is provided, the electronic device comprising:

[0014] At least one processor; and a memory communicatively connected to the at least one processor;

[0015] The memory stores a computer program that can be executed by at least one processor, which enables the at least one processor to perform the leaf feeding method in any embodiment of the present invention.

[0016] According to another aspect of the present invention, a computer-readable storage medium is provided that stores computer instructions for causing a processor to execute and implement the leaf-laying and feeding method in any embodiment of the present invention.

[0017] According to another aspect of the present invention, a computer program product is provided, comprising a computer program that, when executed by a processor, implements the leaf-laying and feeding method of any embodiment of the present invention.

[0018] The leaf-laying and feeding method of the present invention includes: obtaining tobacco leaf formulation information, and determining at least i tobacco leaf components and their composition ratios based on the formulation information, where i is a positive integer greater than 10; determining the number of categories for the at least i tobacco leaf components, and dividing the at least i tobacco leaf components based on the number of categories and their composition ratios to obtain at least one leaf-laying task set, wherein the number of leaf-laying task sets is the same as the number of categories; determining the leaf-laying conveyor line for each leaf-laying task set, determining the leaf-laying control information for each tobacco leaf component in each leaf-laying task set based on the leaf-laying conveyor line and the composition ratios of each tobacco leaf component in each leaf-laying task set, and executing the leaf-laying and feeding task based on the leaf-laying control information for each tobacco leaf component in each leaf-laying task set. The technical solution of this invention first analyzes the tobacco leaf formulation information to obtain the various tobacco leaf components and their composition ratios. Then, according to the number of categories of tobacco leaf components and their composition ratios, the various tobacco leaf components are divided into multiple leaf-laying task sets. This ensures that the total composition ratio of each leaf-laying task set is as equal or as similar as possible (composition ratio difference not exceeding 0.5%, 0.2%, etc.), thereby guaranteeing that the feeding time of each leaf-laying task set is equal or as similar as possible (e.g., time difference not exceeding [amount missing]). The system employs various control mechanisms, including a 30-minute time limit, a time difference not exceeding 20 minutes, a time difference not exceeding 1% of the total time, and a time difference not exceeding 0.5% of the total time. It also assigns different leaf-laying control information (e.g., feeding speed and number of feeding points) to tobacco leaf components with different proportions. Each leaf-laying conveyor line executes the leaf-laying and feeding tasks for each tobacco component in parallel or sequentially. This simple, low-cost, efficient, and intelligent approach improves feeding efficiency and the utilization rate of feeding points on the leaf-laying conveyor line, enhancing the production flow and effectiveness of the re-drying plant. This solves the problem of increasing complexity and resource demand in the traditional method of matching feeding points to each component material with a fixed number of feeding points on the leaf-laying conveyor line. It also addresses the issue of varying material requirements leading to some feeding points being idle for extended periods, reducing the utilization rate of the feeding points on the leaf-laying conveyor line.

[0033] Figure 1 This is a flowchart illustrating a leaf-laying and feeding method provided by the present invention. This embodiment is applicable to improving feeding efficiency and utilization rate of feeding points on the leaf-laying conveyor line, enhancing production smoothness and efficiency in re-drying plants, etc. The method can be executed by the leaf-laying and feeding device provided by the present invention. This device can be implemented in hardware and / or software. In a specific embodiment, the device can be integrated into an electronic device. The following embodiments will illustrate this using the integration of the device into an electronic device as an example. (Refer to...) Figure 1 The method specifically includes the following steps:

[0034] S101. Obtain the formulation information of tobacco leaves, and determine the composition ratio of at least i tobacco leaf components and at least i tobacco leaf components based on the formulation information.

[0035] Tobacco leaves are usable tobacco products obtained by mixing various materials in certain proportions (for example, the formula for cigar-flavored cigarettes is 80% conventional tobacco leaves + 12% expanded tobacco stems + 8% reconstituted tobacco leaves processed by papermaking) and undergoing corresponding processing. The tobacco leaf formula information can be understood as the material information of the tobacco leaves corresponding to the production task currently being performed by the re-drying plant (the compositional materials of the tobacco leaves and the compositional proportions of each component), and the sum of the compositional proportions of the tobacco leaf components is 100%. Generally, tobacco leaves involve at least 10 components, so i is a positive integer greater than 10.

[0036] Figure 2 This is a schematic diagram of formula information provided by the present invention. The serial number can be understood as the sequence number of each tobacco leaf component material; the material number can be understood as the number of the tobacco leaf component material, with a one-to-one correspondence between the material number and the tobacco leaf component material; the material name can be understood as the name or identifier of the tobacco leaf component material, with a one-to-one correspondence between the material name and the tobacco leaf component material; the feeding amount can be understood as the weight of the tobacco leaf component material required in the tobacco leaf laying and feeding task, which can be expressed in units of weight (in dan). The composition ratio is the proportion of the weight of the current tobacco leaf component material required in the tobacco leaf laying and feeding task to the total weight of the material. Figure 2 Taking the formula information shown as an example, i is 8, and the tobacco leaf components are material 1, material 2, material 3, material 4, material 5, material 6, material 7 and material 8, where the composition ratio of material 1 is y1%, the composition ratio of material 2 is y2%, the composition ratio of material 3 is y3%, the composition ratio of material 4 is y4%, the composition ratio of material 5 is y5%, the composition ratio of material 6 is y6%, the composition ratio of material 7 is y7%, and the composition ratio of material 8 is y8.

[0037] The advantage of this setup is that it allows for precise determination of the tobacco leaf components and their proportions, enabling the determination of leaf-laying control information for each component and improving the leaf-laying and feeding efficiency in the re-drying plant.

[0038] Different tobacco leaf components have different composition ratios. The higher the proportion of a component, the longer the feeding time and the higher the feeding speed; conversely, the lower the proportion, the shorter the feeding time and the lower the feeding speed. However, each tobacco leaf component requires at least one feeding point. Components with very low proportions (e.g., no more than 0.5%, 1%, or 1.5%, the specific criteria depending on the total weight of the tobacco and the control logic of the feeding process) have very short feeding times, resulting in longer idle times and low utilization rates at their corresponding feeding points. In complex formulations, with a large number of tobacco leaf components, there may be multiple components with very low proportions. Assigning a feeding point to each of these components would easily lead to uneven utilization of the feeding points and low feeding performance. Therefore, the present invention determines at least i tobacco leaf components and the composition ratio of at least i tobacco leaf components based on formula information, including: parsing the formula information to obtain at least j tobacco leaf components and the composition ratio of at least j tobacco leaf components, where j is a positive integer greater than or equal to i; merging tobacco leaf components whose composition ratio is less than a preset ratio threshold among the at least j tobacco leaf components to obtain at least i tobacco leaf components, and determining the composition ratio of at least i tobacco leaf components based on the material merging result.

[0039] The preset proportion threshold can be understood as a criterion for judging whether the composition ratio of tobacco leaf components is too small. The preset proportion threshold can be, for example, 0.5%, 1%, 1.5%, etc., and the specific value is related to the total weight of the tobacco leaf material and the control logic of the feeding process; this invention does not limit this. When the composition ratio of tobacco leaf components is less than the preset proportion threshold, it is considered that the composition ratio of the tobacco leaf components is too small, which easily leads to long-term idle periods at the feeding points. This invention merges all tobacco leaf components with a composition ratio less than the preset proportion threshold to form a new tobacco leaf component. The composition ratio of the new tobacco leaf component is the sum of the composition ratios of the tobacco leaf components with a composition ratio less than the preset proportion threshold, which can effectively reduce the number of feeding points used and the idle time, improving the feeding performance of the feeding process.

[0040] For example, assuming the preset proportion threshold is 1%, the tobacco leaf components are material 1, material 2, material 3, material 4, material 5, material 6, material 7 and material 8, with the composition proportion of material 1 being y1%, material 2 being y2%, material 3 being y3%, material 4 being y4%, material 5 being y5%, material 6 being y6%, material 7 being y7% and material 8 being y8%. Where y5 is 0.8, y7 is 0.5, and y8 is 0.9, materials 5, 7, and 8 are merged. The resulting tobacco leaf components are materials 1, 2, 3, 4, 6, and 9. Material 9 is a mixture of materials 5, 7, and 8 (mixing ratio: material 5: material 7: material 8 = 0.8: 0.5: 0.9). The composition ratio of material 1 is y1%, material 2 is y2%, material 3 is y3%, material 4 is y4%, material 6 is y6%, and material 9 is 2.2%. The advantage of this setup is that it allows for pre-treatment of the tobacco leaf components, reducing the amount of components with low proportions, maximizing the utilization rate of feed resources, and improving the performance of the feeding process.

[0041] S102. Determine the number of classifications for at least i tobacco leaf components, and divide the at least i tobacco leaf components based on the number of classifications and the composition ratio of the at least i tobacco leaf components to obtain at least one leaf-laying task set.

[0042] A re-drying plant typically includes six leaf-laying conveyor lines. To improve leaf-laying efficiency, at least i tobacco leaf components can be divided into multiple leaf-laying tasks. Multiple leaf-laying conveyor lines can then be used to perform the leaf-laying and feeding of tobacco leaf components in parallel, thereby accelerating the leaf-laying efficiency.

[0043] The number of tobacco leaf component material classifications can be understood as the number of divisions of tobacco leaf component materials. Generally, the number of tobacco leaf component material classifications is a positive factor of the leaf-laying conveyor lines in the re-drying plant. Taking a re-drying plant with 6 leaf-laying conveyor lines as an example, the number of tobacco leaf component material classifications includes 1, 2, 3, and 6. The number of leaf-laying task sets is the same as the number of classifications. At least one leaf-laying task set can be understood as the result of leaf-laying task division. To ensure that the time spent on each leaf-laying task is equal or not significantly different after classification, the tobacco leaf component materials are divided according to the number of classifications and the composition ratio of each tobacco leaf component material, so as to make the composition ratio of tobacco leaf component materials in each leaf-laying task set as similar as possible after division. For example, when the number of categories is 2, a 50% composition ratio will be used as a reference, and at least i tobacco leaf components will be divided based on their composition ratios. The goal is to make the composition ratios of the tobacco leaf components in the two divided leaf-laying task sets as close to 50% as possible (considering that the composition ratios of tobacco leaf components are fixed and may not be exactly 50%, some deviation in the division results is allowed, but generally, the deviation from 50% will be no more than 1% or 2% to ensure the feeding effect). When the number of categories is 3, a 33.33% composition ratio will be used as a reference, and at least i tobacco leaf components will be divided based on their composition ratios. The goal is to make the composition ratios of the tobacco leaf components in the three divided leaf-laying task sets as close to 33.33% as possible.

[0044] Specifically, the number of categories for tobacco leaf components can be preset, determined based on the category number command received through the interactive interface, or determined according to the range of the number of tobacco leaf components. For example, when the number of tobacco leaf components is less than 8, the number of categories for tobacco leaf components is determined to be 1; when the number of tobacco leaf components is between 8 and 16, the number of categories for tobacco leaf components is determined to be 2; when the number of tobacco leaf components is greater than 16, the number of categories for tobacco leaf components is determined to be 3, and so on. This invention does not limit this.

[0045] For example, dividing at least i tobacco leaf components based on the number of categories and the composition ratio of at least i tobacco leaf components to obtain at least one leaf-laying task set includes: determining the number of leaf-laying task sets based on the number of categories, and determining the material composition ratio of the leaf-laying task sets according to the number of categories and the total material ratio; dividing at least i tobacco leaf components based on the material composition ratio of the leaf-laying task sets and the composition ratio of at least i tobacco leaf components to obtain at least one leaf-laying task set.

[0046] The total material proportion is 100%. The material composition proportion of each leaf-laying task set is the result of dividing the total material proportion by the number of categories. For example, when the number of categories is 2, the material composition proportion of the leaf-laying task set is 100%; when the number of categories is 2, the material composition proportion of the leaf-laying task set is 50%; when the number of categories is 3, the material composition proportion of the leaf-laying task set is 33.33%, and so on. It is worth noting that the material composition proportion of each leaf-laying task set must be equal to 100%.

[0047] Specifically, taking a 50% material composition ratio for the leaf-laying task set as an example, based on the material composition ratio of the leaf-laying task set and the composition ratio of at least i tobacco leaf components, the at least i tobacco leaf components are divided to obtain at least one leaf-laying task set. This can be understood as integrating the various tobacco leaf components according to a 50% composition ratio, ensuring that the integrated structure of the tobacco leaf components is equal to or infinitely close to 50%. It is worth noting that during the division, the quantity of tobacco leaf components in each leaf-laying task set should be kept as equal as possible to avoid uneven distribution of tobacco leaf components or too many or too few tobacco leaf components in a certain leaf-laying task set, thus ensuring the stability, reliability, and feasibility of the feeding operation.

[0048] Figure 3 This is a schematic diagram of a leaf-laying task set provided by the present invention. Figure 3 A checkmark under the leaf-laying task set indicates that the current leaf-laying task set includes the material, while no checkmark indicates that the current leaf-laying task set does not include the material. This invention also matches different feeding points to tobacco leaf components based on their feeding amounts. For example, more feeding points are set for tobacco leaf components with higher feeding amounts, and fewer feeding points are set for tobacco leaf components with lower feeding amounts, to ensure that the feeding time for each tobacco leaf component is not significantly different, thereby maximizing the utilization rate of feeding resources while ensuring feeding effectiveness.

[0049] S103. Determine the leaf-laying conveyor line for each leaf-laying task set. Based on the leaf-laying conveyor line for each leaf-laying task set and the composition ratio of each tobacco component material in each leaf-laying task set, determine the leaf-laying control information for each tobacco component material in each leaf-laying task set, and execute the leaf-laying and feeding task for tobacco based on the leaf-laying control information for each tobacco component material in each leaf-laying task set.

[0050] Determining the leaf-laying conveyor lines for each leaf-laying task set can be understood as specifying which leaf-laying conveyor lines in the re-drying plant will be used to perform the leaf-laying work corresponding to which leaf-laying task set. On one hand, the leaf-laying conveyor lines can be determined based on the division of the leaf-laying task sets. For example, when all leaf-laying conveyor lines are used and each leaf-laying task set is executed in parallel, if there are two leaf-laying task sets, the leaf-laying conveyor lines for leaf-laying task set 1 are determined to be leaf-laying conveyor lines 1, 2, and 3, and the leaf-laying conveyor lines for leaf-laying task set 2 are determined to be leaf-laying conveyor lines 4, 5, and 6. If there are three leaf-laying task sets, the leaf-laying conveyor lines for leaf-laying task set 1 are determined to be leaf-laying conveyor lines 1 and 2, the leaf-laying conveyor lines for leaf-laying task set 2 are determined to be leaf-laying conveyor lines 3 and 4, and the leaf-laying conveyor lines for leaf-laying task set 3 are determined to be leaf-laying conveyor lines 5 and 6. Furthermore, each leaf-laying task set can be executed sequentially, or partially in parallel, with the rest waiting for the preceding leaf-laying task set to complete before execution. The leaf-laying conveyor line can also be partially used, and this invention does not limit this.

[0051] On the other hand, the leaf-laying conveyor line of each leaf-laying task set can be determined according to control instructions. In this way, determining the leaf-laying conveyor line of each leaf-laying task set includes: displaying at least one leaf-laying task set on the control information interaction interface, and determining the leaf-laying conveyor line of each leaf-laying task set according to the leaf-laying control parameters received by the information interaction interface.

[0052] The control information interaction interface displays at least one leaf-laying task set to enable users to understand the relevant information of the leaf-laying task set. The leaf-laying control parameters received by the information interaction interface can be understood as the leaf-laying line selection requirements issued by the user based on the information displayed by the information interaction interface, which are used to indicate the leaf-laying conveyor line corresponding to each leaf-laying task set. Figure 4 This is a schematic diagram illustrating the relationship between a leaf-laying task set and a leaf-laying conveyor line provided by the present invention. Figure 4 It can be seen that the leaf laying conveyor lines for leaf laying task set 1 are leaf laying conveyor line 1 and leaf laying conveyor line 3, the leaf laying conveyor lines for leaf laying task set 2 are leaf laying conveyor line 4 and leaf laying conveyor line 6, and the leaf laying conveyor lines for leaf laying task set 3 are leaf laying conveyor line 2 and leaf laying conveyor line 5.

[0053] Specifically, the leaf-laying transport line for each leaf-laying task set is used to indicate the execution relationship between the leaf-laying task sets, including parallel execution and / or sequential execution. Figure 4The execution relationship between the leaf-laying task sets is parallel execution. Further, assuming that leaf-laying task set 1, leaf-laying task set 2, and leaf-laying task set 3 each include leaf-laying conveyor line 1, leaf-laying conveyor line 2, leaf-laying conveyor line 3, leaf-laying conveyor line 4, leaf-laying conveyor line 5, and leaf-laying conveyor line 6, then the execution relationship between leaf-laying task set 1, leaf-laying task set 2, and leaf-laying task set 3 is sequential execution; assuming that leaf-laying task set 1 includes leaf-laying conveyor line 1, leaf-laying conveyor line 2, and leaf-laying conveyor line 3, leaf-laying task set 2 includes leaf-laying conveyor line 1, leaf-laying conveyor line 2, and leaf-laying conveyor line 3, and leaf-laying task set 3 includes leaf-laying conveyor line 4, leaf-laying conveyor line 5, and leaf-laying conveyor line 6, then the execution relationship between leaf-laying task set 1 and leaf-laying task set 2 is sequential execution, the execution relationship between leaf-laying task set 1 and leaf-laying task set 3 is parallel execution, and there is no obvious correlation between leaf-laying task set 2 and leaf-laying task set 3.

[0054] For any set of leaf-laying tasks, based on the leaf-laying conveyor line of the task set and the composition ratio of each tobacco component material in the task set, determine the leaf-laying control information for each tobacco component material in the task set, including:

[0055] 1) Based on the number of leaf-laying conveyor lines corresponding to the leaf-laying task set and the composition ratio of each tobacco component material in the leaf-laying task set, determine the composition ratio of each tobacco component material on the current leaf-laying conveyor line. The current leaf-laying conveyor line is one of the leaf-laying conveyor lines corresponding to the leaf-laying task set.

[0056] Generally, when a leaf-laying task set corresponds to multiple leaf-laying conveyor lines, each conveyor line performs the same task. This is equivalent to evenly distributing the feeding tasks of each tobacco leaf component material in the leaf-laying task set to each conveyor line. The composition ratio of each tobacco leaf component material in the leaf-laying task set is evenly distributed based on the number of conveyor lines corresponding to the task set and the composition ratio of each material in the task set. The result is the composition ratio of each tobacco leaf component material on the current leaf-laying conveyor line.

[0057] 2) Based on the number of feeding points on the current leaf-laying conveyor line and the composition ratio of each tobacco component material on the current leaf-laying conveyor line, determine the feeding speed of each tobacco component material on the current leaf-laying conveyor line and the correspondence between each tobacco component material on the current leaf-laying conveyor line and the feeding points on the current leaf-laying conveyor line.

[0058] The feeding point can be understood as a leaf-laying station, that is, a location on the leaf-laying conveyor line where tobacco leaf components can be fed. The leaf-laying conveyor line includes 16 feeding points, therefore the current number of feeding points on the leaf-laying conveyor line is 16. This invention allocates corresponding feeding points according to the composition ratio of the tobacco leaf components, assigning more feeding points and a higher feeding speed to tobacco leaf components with a high composition ratio, and fewer feeding points and a lower feeding speed to tobacco leaf components with a low composition ratio, etc., to uniformly control the feeding time at each feeding point as much as possible. For example, combined with... Figure 3 In Leaf Laying Task Set 1, material xxxxxxx1 requires 6 feeding points, material xxxxxxx4 requires 4 feeding points, and material xxxxxxx6 requires 6 feeding points. In Leaf Laying Task Set 2, material xxxxxxx3 requires 8 feeding points, material xxxxxxx5 requires 4 feeding points, and material xxxxxxx8 requires 6 feeding points. In Leaf Laying Task Set 3, both material xxxxxxx2 and material xxxxxxx7 require 8 feeding points.

[0059] It is worth noting that this invention can also employ a combined primary and backup feeding method. That is, each tobacco component material occupies at least two feeding points, one as the primary feeding point and the other as the backup feeding point. When the tobacco component material at the primary feeding point is exhausted, the tobacco component material at the backup feeding point is used for feeding, and a material transport vehicle replenishes the tobacco component material at the primary feeding point (controlling the material transport vehicle to transport one load of the corresponding tobacco component material to the primary feeding point) to ensure the continuity of the feeding task. Similarly, when the tobacco component material at the backup feeding point is exhausted, the feeding operation returns to using the tobacco component material at the primary feeding point, and a material transport vehicle replenishes the tobacco component material at the backup feeding point. Figure 5 This is a schematic diagram of a leaf-laying conveyor line provided by the present invention. The arrows indicate the transmission direction of the leaf-laying belt. Two feeding points deployed together serve as primary and backup points for each other. For example, feeding point 1 and feeding point 2, feeding point 3 and feeding point 6, etc. The two feeding points that serve as primary and backup points can be managed by a feeding device or staff member, which can further reduce the resources and costs required for feeding work.

[0060] Furthermore, the feeding process can also be carried out without using a primary / backup approach. To ensure the continuity of the feeding operation, when executing the tobacco leaf feeding task based on the leaf laying control information of each tobacco leaf component material in each leaf laying task set, the leaf laying feeding method of the present invention further includes: real-time acquisition of the remaining amount of each tobacco leaf component material in each leaf laying task set; determining the tobacco leaf component material to be replenished (tobacco leaf component material that is about to be exhausted and needs to be replenished in a timely manner) based on the remaining amount of each tobacco leaf component material in each leaf laying task set; generating replenishment control data based on the feeding information of the tobacco leaf component material to be replenished; and controlling the material transport vehicle to run based on the replenishment control data to execute the replenishment task of the tobacco leaf component material to be replenished.

[0061] Among them, the tobacco leaf components to be supplemented are tobacco leaf components whose remaining amount is lower than the preset feeding threshold (an indicator used to measure whether the remaining amount of tobacco leaf components is low) and / or tobacco leaf components whose remaining feeding time is lower than the preset feeding time (an indicator used to measure whether the remaining amount of tobacco leaf components can only support a short feeding time).

[0062] Specifically, different tobacco leaf components have different feeding speeds and consumption rates. Therefore, this invention sets two criteria for determining replenishment: remaining quantity and remaining feeding time, to ensure the continuity of feeding work, reduce the possibility of feeding work interruption, and improve the utilization rate of feeding points.

[0063] Specifically, this invention will deploy a leaf-laying control information interaction interface at each feeding point to indicate, understand and guide the leaf-laying and feeding work at the feeding point. Figure 6 This is a schematic diagram of a leaf-laying control information interaction interface provided by the present invention. Figure 6 As can be seen from the interface, the leaf-laying control information interaction interface can display parameters such as the progress information of the leaf-laying feeding task, the current feeding status, the amount of material fed at one time, and the current feeding point information.

[0064] This invention enables precise material delivery and improves the utilization rate of feeding points through supplementary feeding and main / backup methods, thereby enhancing the production continuity and stability of the re-drying plant, making the leaf-laying and feeding process smoother and more efficient, and improving production flexibility.

[0065] The technical solution of the above embodiments first analyzes the tobacco leaf formulation information to obtain the various tobacco leaf components and their composition ratios. Then, according to the number of tobacco leaf component categories and their composition ratios, the various tobacco leaf components are divided into multiple leaf-laying task sets. This ensures that the total composition ratio of each leaf-laying task set is as equal or as similar as possible (e.g., the difference in composition ratio is no greater than 0.5%, no greater than 0.2%, etc.), so as to guarantee that the feeding time of each leaf-laying task set is equal or as similar as possible (e.g., the time difference is not significant). The time difference is set at 30 minutes or less, no more than 20 minutes, no more than 1% of the total time, and no more than 0.5% of the total time. Different leaf-laying control information (e.g., feeding speed and number of feeding points) is assigned to tobacco leaf components with different proportions. Each leaf-laying conveyor line executes the leaf-laying and feeding tasks for each tobacco component in parallel or sequentially. This simple, low-cost, efficient, and intelligent method improves feeding efficiency and the utilization rate of feeding points on the leaf-laying conveyor line, enhancing the production flow and effectiveness of the re-drying plant. This solves the problem that in the method of matching feeding points to each component with a fixed number of feeding points on the leaf-laying conveyor line, the increasing number of leaf-laying rounds required for the feeding task, the more scheduling work is done, and the higher the complexity and resource demand of the leaf-laying and feeding task becomes as the number of tobacco components increases. It also solves the problem that the demand for different components varies, and the method of matching feeding points to each component can easily lead to some feeding points being idle for extended periods, reducing the utilization rate of the feeding points on the leaf-laying conveyor line.
