Description

Technical Field

[0001] The present application relates to a method for proportioning and packing original tobacco and feeding materials into a formula library, belonging to the technical field of cigarette production. Background Art

[0002] In the traditional original tobacco formula work of redrying, the direct feeding mode of manually spreading leaves and mixing is adopted, without configuring an original tobacco chemical composition acquisition and regulation system, nor a spreading proportion and formula feeding control system. There is no data support for the chemical values of the formula tobacco leaves. The interference of human factors makes the formula management and scheduling difficult, the production efficiency low, and the site relatively chaotic. Only rough formula homogenization can be achieved, and it is not easy to realize flexible and fine formula threshing production.

[0003] Therefore, a method for proportioning and packing original tobacco and feeding materials into a formula library is proposed to realize the automatic formula module formation and homogenized out-of-store production of original tobacco for redrying and threshing. Summary of the Invention

[0004] In order to overcome the problems in the background art, the present application controls and manages the relevant operations of processes such as humidifying and preparing materials, spreading and feeding materials, proportioning and packing, warehousing, and homogenized formula out-of-store through calculation, improves the stability of tobacco leaf processing proportioning and packing and formula library feeding, and the uniformity of tobacco leaf mixing and blending, enables the tobacco leaves to meet the requirements of the threshing plan, physical blending, and homogenized formula, formulates an out-of-store strategy and an out-of-store queue through homogenized calculation, maximizes the out-of-store efficiency, enhances the refined, modular, and homogenized formula processing level of original tobacco, and realizes the automatic formula module formation and homogenized out-of-store of original tobacco for redrying and threshing.

[0005] In order to overcome the problems in the background art, the present application is realized through the following technical solutions:

[0006] A method for proportioning and packing original tobacco and feeding materials into a formula library includes the following steps:

[0007] Obtain the inventory information of the tobacco leaves in the original tobacco storage warehouse, generate a "threshing plan sheet" according to the formula requirements, calculate the number of feeding frames required for the day, and conduct the warehousing planning of the humidifying and preparing warehouse and the batch warehousing of the humidifying and preparing warehouse;

[0008] Generate an out-of-store plan for the humidifying warehouse according to the feeding amount required for each round of the day, and determine the material out-of-store plan for the humidifying warehouse preparation warehouse and the uniform distribution plan for the tobacco leaves on the spreading line;

[0009] Calculate the number of packages per batch and the single-box loading amount according to the total feeding weight and the number of boxes required for the production of each batch of tobacco leaves, the measured value of the tobacco leaves before entering the packing station, and the process requirements, and conduct automatic packing;

[0010] According to the requirements of the batching plan and homogenization, perform the calculation of the single batch out-of-warehouse for homogenization, generate more than two homogenization control plans, plan the collocation sequence of the out-of-warehouse cigarette cartons, and generate the out-of-warehouse plan, where the requirements related to homogenization include blending requirements, grade homogenization, chemical information homogenization, weight homogenization, and formula.

[0011] Optionally, the inbound planning for the humidifying and stockpiling warehouse includes:

[0012] Query the inventory information such as the chemical composition, grade, and weight of each single-frame tobacco leaf in the raw tobacco storage warehouse, convert the required weight of tobacco leaves of each grade in the "production formula sheet" into the actual number of tobacco frames in stock, and collocate the multi-frame tobacco leaves of the same grade according to the balance of nicotine values; if there are too many grades with a small proportion in the "production formula sheet", first perform grade merging through "grade mixing piles", that is, merge multiple small grades into one large grade, and then perform the calculation of the "batching plan sheet";

[0013] According to the formula composition information and the number of tobacco leaf grades in the "batching plan sheet", perform "module splitting". According to the principle that the number of small modules is less than or equal to the number of turning and discharging machines and the sum of the proportions of each small module is equal to the number of turning and discharging machines, split and recombine all grades in the batching plan into 1-6 small module feeding units according to a certain ratio, and determine the number of frames and weight of each grade of tobacco leaves constituting each small module. If the number of grades is less than the number of laying platforms, it is possible to choose not to split the small modules;

[0014] According to the feeding amount that the humidifying and stockpiling warehouse can store in one day and the small module tobacco leaves after "module splitting" in the production feeding, perform "round splitting", split the total batching plan into multiple rounds according to the feeding amount, place the tobacco frames of each round in turn in the stockpiling and humidifying warehouse for humidification, and generate the "requirement list for the humidifying and stockpiling warehouse" according to the required number of tobacco frame grades and the storage location situation of the humidifying and stockpiling warehouse for each feeding round;

[0015] Optionally, the out-of-warehouse plan for the humidifying warehouse and the uniform distribution plan for tobacco leaves on the laying line include:

[0016] According to the number of grades and the number of small modules, select the feeding mode of the laying line. According to the feeding mode of the laying line, follow the principle of single-line grade crossing and multi-line grade equalization. The tobacco leaves of the same grade are not adjacent on the same laying line platform, and the same large grade is evenly distributed on different laying lines. Select the optimal distribution method and generate the "leaf laying plan" through calculation;

[0017] According to the total feeding amount and the storage location information of the stockpiling and humidifying warehouse, generate the "feeding round plan" and the "stockpiling plan". The "feeding round plan" includes the variety, grade, nicotine, feeding amount, feeding rate, and feeding platform of the tobacco leaves that need to be fed on each laying line for each round; the "stockpiling plan" includes the variety, grade, nicotine, required number of stockpiling frames, and storage location number in the humidifying warehouse of the tobacco leaves required for each round of feeding.

[0018] Optionally, the leaf laying line feeding mode includes:

[0019] Single-grade feeding equipment. When the number of grades is 1, no small module splitting is performed, and no grade blending is carried out. Leaf laying and feeding are performed at 10 stations on one side of a single leaf laying line, and the next round of feeding preparation is carried out simultaneously on the other side. There is no blending relationship between stations, and direct feeding and boxing are carried out until the end of the grade;

[0020] Batch single-line feeding equipment. When the number of small module splits is 1 and the number of small module grades ≤ 10, 10 stations on one side of a single leaf laying line are used for leaf laying and feeding, and the next round of feeding preparation is carried out simultaneously on the other side. All grades of the full formula are fed through a single leaf laying line. Each leaf laying line contains complete formula grades, and the tobacco leaves of the same batch enter the same boxing station;

[0021] Batch multi-line feeding equipment. When the number of small module splits is 1 and 10 < the number of small module grades ≤ 20, two leaf laying lines are used for combined feeding. One leaf laying line with 20 stations on both sides is used for leaf laying and feeding, and the other leaf laying line with 20 stations on both sides is used for the next round of feeding preparation. All grades of the full formula are fed through two leaf laying lines. The tobacco leaves of up to 20 grades in the same batch are blended and then all enter a single boxing station;

[0022] Feeding by small module combined blending. When the number of small module splits > 1 and the number of small module grades ≤ 10, according to the module splitting results, the grade blending of tobacco leaves of each module is carried out on the leaf laying line;

[0023] Full-station micro-module feeding. When 10 ≤ the number of micro-module grades ≤ 20, one leaf laying line with 20 workstations is used for one-time feeding preparation and feeding. When 20 ≤ the number of micro-module grades ≤ 40, two leaf laying lines with 40 workstations are used for one-time feeding preparation and feeding. Feeding is carried out in multiple rounds according to production batches, and the next round of feeding preparation is carried out only after all feeding is completed, realizing the function that the tobacco leaves of up to 40 grades are blended and then all enter a single boxing station;

[0024] Optionally, calculate the number of boxes per batch and the loading amount per box, including:

[0025] Set the loading amount per box according to the volume of the tobacco boxes in the high-rise warehouse, the total weight of the tobacco leaves in the batch,

[0026] Estimated number of boxes per batch = (total weight of tobacco leaves in the batch) / (loading amount per box)

[0027] The actual number of boxes is rounded up to a multiple of the number of box turning and dumping machines. Reverse calculation: loading amount per box = (total weight of tobacco leaves in the batch) / (actual number of boxes); If the packing weight is low due to the fluffiness of the tobacco leaves, the number of boxes is increased by twice the number of box turning and dumping machines;

[0028] Calculation methods for different feeding modes:

[0029] Single - grade tobacco leaves are packed into boxes, and the loading capacity per box = total weight of tobacco leaves in a batch / number of boxes packed in a batch;

[0030] Packed by batch mixing, the loading capacity per box = ∑(proportion of small - grade weight × total weight of tobacco leaves in a batch) / number of boxes packed in a batch;

[0031] Packed by pre - mixing in small modules, the number of boxes packed in a batch = ∑ number of boxes packed in small modules. The number of boxes packed in a small module = (ratio of small modules / number of tilting and discharging machines) × number of boxes packed in a batch. The loading capacity per box of a small module = (∑ proportion of weights of each grade contained in a small module × total weight of tobacco leaves in a batch) / number of boxes packed in a small module.

[0032] Optionally, the outbound plan includes:

[0033] Outbound of single - grade tobacco leaves, outbound by batch mixing, outbound by mixing in small - module combinations, and direct outbound of raw tobacco in single grades.

[0034] Optionally, the homogenization calculation method of the outbound method includes:

[0035] Taking the tobacco boxes in the high - rack warehouse as the basic outbound unit, the total number of outbound tobacco boxes is equal to the number of boxes packed in a batch. The outbound tobacco boxes are distributed to the corresponding tilting and discharging machine channels for feeding. The number of tilting and discharging machines to be activated is selected according to the number of modules.

[0036] For outbound of single - grade tobacco leaves and outbound by batch mixing, after selecting the outbound tobacco boxes from all the tobacco boxes in the module, they are evenly distributed to N tilting and discharging machines for blending and feeding.

[0037] For outbound by mixing in small - module combinations and packing, first calculate the number of outbound tobacco boxes required for each small module according to the ratio of small modules, select from the corresponding tobacco boxes of each small module, and different small modules are distributed to different tilting and discharging machines for blending and feeding.

[0038] The chemical - value equilibrium indicators for outbound tobacco boxes are nicotine, reducing sugar, total sugar, total nitrogen, potassium, chlorine, color, sugar - alkali ratio, and two - sugar ratio. The chemical - value equilibrium indicators are comprehensively calculated according to their respective weights.

[0039] Inter - batch equilibrium, the average chemical values of all tobacco boxes between each outbound batch are balanced.

[0040] The average chemical value X = ∑ chemical values of tobacco boxes / number of boxes packed in a batch.

[0041] For each batch, based on X, select appropriate tobacco boxes according to the number of boxes packed in a batch, so that the X of the batch is approximately equal to the total X.

[0042] Intra - batch equilibrium, within the same batch, the chemical values of tobacco leaves are balanced between the outbound groups. Calculate according to the ascending, descending, and equal - division principles of chemical values between groups respectively, and select a better method for outbound after previewing the outbound queue manually.

[0043] Calculate the feeding rate ratio of each turnover and feeding machine. The turnover and feeding machine controls the flow of the electronic scale according to this ratio for uniform feeding, so as to achieve the proportional blending of tobacco leaves within the group. The calculation method is as follows:

[0044] V 通道1 : V 通道2 : …: V 通道n =

[0045] ∑ 通道1投料总量 : ∑ 通道2投料总量 : …: ∑ 通道n投料总量

[0046] The cigarette boxes in the high-rise warehouse follow the principle of first-in, first-out and are preferentially selected according to the set storage time.

[0047] Optionally, the homogenization outbound plan includes static outbound and dynamic outbound. When the total amount of the collating list can all enter the high-rise warehouse, the static outbound method is selected to generate all outbound queues at one time; dynamic outbound is applicable to the situation where the total amount of the collating list is large and the capacity of the high-rise warehouse is insufficient. When the total amount of the collating list cannot all enter the high-rise warehouse, as long as all the cigarette frames of a batch of full formula enter the warehouse, the dynamic outbound can be started.

[0048] The beneficial effects of the present application are as follows:

[0049] The present application controls and manages the relevant operations of processes such as humidifying and preparing materials, laying and feeding leaves, proportioning and packing, warehousing, and homogenization formula outbound by calculation, improves the stability of tobacco leaf processing proportioning and packing and the feeding of the formula library, and the uniformity of tobacco leaf mixing and blending, enables the tobacco leaves to meet the requirements related to the collating plan, physical blending, and homogenization formula. Through homogenization calculation, the outbound strategy and outbound queue are formulated to maximize the outbound efficiency, improve the refined, modular, and homogenized formula processing level of the raw tobacco, and realize the automatic formula grouping and homogenization outbound of the threshed and redried raw tobacco.

[0059] The technical solutions of the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0060] Figure 1 It is a schematic flow chart of the method for proportioning and packing raw tobacco and feeding materials into the formula library shown in the embodiment of the present application.

[0061] Embodiment 1:

[0062] See Figure 1 , a method for proportioning and packing raw tobacco and feeding materials into the formula library, including:

[0063] S101. Obtain the inventory information of the tobacco leaves in the raw tobacco storage warehouse, generate a "blending plan sheet" according to the formula requirements, calculate the number of feeding frames required on the same day, and conduct the warehousing planning of the humidifying and preparing materials warehouse and the batch warehousing of the humidifying and preparing materials warehouse;

[0064] Optionally, the warehousing planning of the humidifying and preparing materials warehouse includes:

[0065] Query the inventory information such as the chemical composition, grade, and weight of each frame of tobacco leaves in the raw tobacco storage warehouse, convert the required weight of each grade of tobacco leaves in the "production formula sheet" into the actual number of tobacco frames in stock, and match the multiple frames of tobacco leaves of the same grade according to the balance of nicotine values; if there are too many grades with a small proportion in the "production formula sheet", first merge the grades through "grade stacking", that is, merge multiple small grades into one large grade, and then calculate the "blending plan sheet";

[0066] According to the formula composition information and the number of tobacco leaf grades in the "blending plan sheet", conduct "module splitting", and according to the principle that the number of small modules is less than or equal to the number of turnover and dumping machines and the sum of the proportions of each small module is equal to the number of turnover and dumping machines, split and recombine all the grades in the blending plan into 1-6 small module feeding units according to a certain ratio, determine the number of frames and the weight of each grade of tobacco leaves constituting each small module. If the number of grades is less than the number of laying positions, it is possible not to split the small modules;

[0067] According to the feeding quantity that the humidifying and stockpiling warehouse can store in one day and the small-module tobacco leaves after "module splitting" in the production that requires feeding, "round splitting" is carried out. The total amount of the blending plan is split into multiple rounds according to the feeding quantity. The tobacco frames of each round are sequentially placed in the stockpiling and humidifying warehouse for humidification. According to the quantity of tobacco frame grades required for the feeding round and the storage location situation of the humidifying and stockpiling warehouse, a "material requisition form for the humidifying and stockpiling warehouse" is generated.

[0068] S102. According to the feeding quantity required for each round of the day, generate an outbound plan for the humidifying warehouse, and determine the material outbound plan for the humidifying and stockpiling warehouse and the uniform distribution plan for the tobacco leaves on the leaf laying line;

[0069] Optionally, the material outbound plan for the humidifying and stockpiling warehouse and the uniform distribution plan for the tobacco leaves on the leaf laying line include:

[0070] According to the number of grades and the number of small modules, select the feeding mode for the leaf laying line. According to the feeding mode of the leaf laying line, following the principle of single-line grade crossing and multi-line grade equalization, the tobacco leaves of the same grade are not adjacent on the same leaf laying line station, the same large grade is evenly distributed on different leaf laying lines, select the optimal distribution method, and generate a "leaf laying plan" through calculation;

[0071] According to the total feeding quantity and the storage location information of the humidifying and stockpiling warehouse, generate a "feeding round plan" and a "stockpiling plan". The "feeding round plan" includes the variety, grade, nicotine, feeding quantity, feeding rate, and feeding station of the tobacco leaves that need to be fed on each leaf laying line for each round; the "stockpiling plan" includes the variety, grade, nicotine, number of stockpiling frames required for each round of feeding, and the storage location number of the humidifying warehouse.

[0072] Optionally, the feeding mode of the leaf laying line includes:

[0073] Single-grade feeding and stockpiling. When the number of grades is 1, no small-module splitting is carried out, and no grade blending is carried out. The leaf laying and feeding are carried out on 10 stations on one side of a single leaf laying line, and the next round of stockpiling is carried out on the other side at the same time. There is no blending relationship between each station, and the feeding is directly packed into boxes until the end of the grade;

[0074] Batch single-line feeding and stockpiling. When the number of small-module splits is 1 and the number of small-module grades ≤ 10, 10 stations on one side of a single leaf laying line are used for leaf laying and feeding, and the next round of stockpiling is carried out on the other side at the same time. All grades of the full formula are fed through a single leaf laying line. Each leaf laying line contains the complete formula grades, and the tobacco leaves of the same batch enter the same packing station;

[0075] Batch multi-line feeding and stockpiling. When the number of small-module splits is 1 and 10 < the number of small-module grades ≤ 20, two leaf laying lines are used for combined feeding. One leaf laying line with 20 stations on both sides is used for leaf laying and feeding, and the other leaf laying line with 20 stations on both sides is used for the next round of stockpiling. All grades of the full formula are fed through two leaf laying lines. At most 20 grades of tobacco leaves in the same batch are mixed and then all enter a packing station;

[0076] Mix and charge materials according to small modules. When the number of split small modules > 1 and the number of small module grades ≤ 10, according to the module split results, mix the tobacco leaf grades of each module on the leaf spreading line.

[0077] Full-station micro-module charging. When 10 ≤ the number of micro-module grades ≤ 20, use 20 workstations on one leaf spreading line for one-time material preparation and charging. When 20 ≤ the number of micro-module grades ≤ 40, use 40 workstations on two leaf spreading lines for one-time material preparation machine charging. Charge in multiple rounds according to production batches, and only start the next round of material preparation after all charging is completed, realizing the function that the tobacco leaves of up to 40 grades are mixed and then all enter one packing station.

[0078] S103. According to the total weight and number of boxes required for each batch of tobacco leaf production, the measurement value before the tobacco leaves enter the packing station, and the process requirements, calculate the number of boxes per batch and the loading amount per box, and perform automatic packing.

[0079] Optionally, calculating the number of boxes per batch and the loading amount per box includes:

[0080] Set the loading amount per box according to the volume of the tobacco leaf boxes in the high-rise warehouse, the total weight of the batch of tobacco leaves

[0081] Estimated number of boxes per batch = (total weight of batch of tobacco leaves) / (loading amount per box)

[0082] The actual number of boxes is rounded up to a multiple of the number of turnover and dumping machines, and the loading amount per box is inversely deduced = (total weight of batch of tobacco leaves) / (actual number of boxes); if the packing weight is low due to the fluffiness of the tobacco leaves, the number of boxes is increased by twice the number of turnover and dumping machines.

[0083] Calculation methods for different charging modes:

[0084] Single-grade tobacco leaf packing, loading amount per box = total weight of batch of tobacco leaves / number of boxes per batch;

[0085] Batch mixing and packing, loading amount per box = ∑(proportion of small grade weight × total weight of batch of tobacco leaves) / number of boxes per batch;

[0086] Pre-mixing and packing according to small module combination, number of boxes per batch = ∑ number of small module boxes, number of small module boxes = (small module ratio / number of turnover and dumping machines) × number of boxes per batch, loading amount per small module box = (∑ proportion of weights of each grade contained in the small module × total weight of batch of tobacco leaves) / number of small module boxes.

[0087] S104. According to the blending plan and homogenization-related requirements, perform homogenization single-batch outbound calculation, generate more than two homogenization control plans, plan the matching order of the outbound tobacco leaf boxes, and generate an outbound plan, where the homogenization-related requirements include blending requirements, grade homogenization, chemical information homogenization, weight homogenization, and formula.

[0088] Optionally, the outbound plan includes:

[0089] Outbound of single-grade tobacco leaves, outbound by batch blending, outbound by small-module combination blending, and direct outbound of raw tobacco in single grade.

[0090] Optionally, the homogenization calculation method of the outbound method includes:

[0091] Taking the tobacco bins in the high-bay warehouse as the basic outbound unit, the total number of outbound tobacco bins is equal to the number of bins packed in a batch. The outbound tobacco bins are distributed to the corresponding tipping machine channels for feeding. The number of tipping machines to be activated is selected according to the number of modules.

[0092] For outbound of single-grade tobacco leaves and outbound by batch blending, after selecting the outbound tobacco bins from all the tobacco bins in the module, they are evenly distributed to N tipping machines for blending and feeding.

[0093] For outbound by small-module combination blending and packing, first calculate the number of outbound tobacco bins required for each small module according to the small-module ratio, select from the corresponding tobacco bins of each small module, and different small modules are distributed to different tipping machines for blending and feeding.

[0094] The chemical value balance indicators for the outbound tobacco bins are nicotine, reducing sugar, total sugar, total nitrogen, potassium, chlorine, color, sugar-alkali ratio, and two-sugar ratio. The chemical value balance indicators are comprehensively calculated according to their respective weights.

[0095] Inter-batch balance, the average chemical values of all tobacco bins are balanced between each outbound batch.

[0096] The average chemical value X = ∑ chemical values of tobacco bins / number of bins packed in a batch.

[0097] For each batch, based on X, select appropriate tobacco bins according to the number of bins packed in a batch, so that the batch X is approximately equal to the total X.

[0098] Intra-batch balance, within the same batch, the chemical values of the tobacco leaves are balanced between the outbound groups. Calculate according to the ascending, descending, and equal-division principles of the chemical values between groups respectively, and select a better method for outbound after manual preview of the outbound queue.

[0099] Calculate the feeding rate ratio of each tipping machine. The tipping machine controls the electronic scale flow according to this ratio for uniform feeding, so as to achieve proportional blending of the tobacco leaves within the group. The calculation method is as follows:

[0100] V 通道1 : V 通道2 :...: V 通道n =

[0101] ∑ 通道1投料总量 : ∑ 通道2投料总量 :...: ∑ 通道n投料总量

[0102] The cigarette boxes in the high-rise warehouse follow the principle of first-in, first-out and are preferentially selected according to the set storage time.

[0103] Optionally, the homogenized outbound method includes static outbound and dynamic outbound. When the total quantity of the collated order can all enter the high-rise warehouse, the static outbound method is selected to generate all outbound queues at one time; dynamic outbound is applicable to the situation where the total quantity of the collated order is large and the capacity of the high-rise warehouse is insufficient. When the total quantity of the collated order cannot all enter the high-rise warehouse, as long as all the cigarette frames of a batch of full-formula enter the warehouse, the dynamic outbound can be started.

[0104] Embodiment 2:

[0105] See Figure 2 , a method for proportioning and packing raw tobacco and feeding materials into the formula library includes the following steps:

[0106] S201. Receive the "production formula sheet" issued by the process management department, obtain the inventory information of the tobacco leaves in the raw tobacco storage warehouse, generate a "collated plan sheet" through calculation, calculate the number of feeding frames required on the same day according to the total number of formula tobacco leaf frames in the production plan, and conduct the warehousing planning for the humidification preparation warehouse and the batch warehousing of the humidification preparation warehouse.

[0107] S201. The warehousing planning for the humidification preparation warehouse includes the following steps:

[0108] S2011. The "production formula sheet" includes the composition information of the modular tobacco leaves, including: the origin, grade, variety of each grade of tobacco leaves, as well as the collocation relationship and weight ratio of different tobacco leaves;

[0109] S2012. The calculation method of the "collated plan sheet" is to query the inventory information such as the chemical composition, grade, and weight of each tobacco leaf frame in the raw tobacco storage warehouse, convert the required weight of each grade of tobacco leaves in the "production formula sheet" into the actual number of tobacco frames in stock (distinguishing between large and small tobacco frames), and collocate the multiple frames of the same grade of tobacco leaves evenly according to the nicotine value; the main order information of the "collated plan sheet" includes: the collated plan period number, the outbound main order number, the outbound date, and the feeding date, and the detailed information includes: the location number, the origin, the grade, the variety, the number of frames of each grade, the chemical composition value, the nicotine collocation information, and the weight; if there are too many grades with a small proportion in the "production formula sheet", the grades can be first merged through "grade mixed stacking", that is, multiple small grades are merged into a large grade, and then the "collated plan sheet" is calculated;

[0110] In S2013, according to the formula composition information and the quantity of tobacco leaf grades in the "Matching Production Plan Sheet", and based on the principle that the quantity of grades is greater than the total number of laying lines, "module splitting" is carried out. The splitting method is to split and recombine all the grades in the matching production plan into 1 - 6 small module feeding units according to a certain ratio based on the principle that the number of small modules is less than or equal to the number of turnover and tipping machines and the sum of the ratios of each small module is equal to the number of turnover and tipping machines (for example, if the small module is split into 2, the ratio is 3:3; if the small module is split into 4, the ratio is 1:1:2:2). Determine the number of frames and weight of each grade of tobacco leaf that makes up each small module, mix and blend them with each other through the laying line, feed each small module one by one and pack it into the formula library. During production, multiple small modules are taken out of the warehouse in proportion to the number of cigarette boxes and combined into a full formula; if the quantity of grades is less than the number of laying positions, it is also possible to choose not to split the small modules, and directly blend all the grades through the laying line to form a full formula for batch laying and feeding;

[0111] In S2014, according to the feeding quantity that the humidifying and stockpiling warehouse can store in one day and the small modules that need to be fed for production, "round - by - round splitting" is carried out on the tobacco leaves after "module splitting" in S2013. The total quantity of the matching production plan is split into multiple rounds according to the feeding quantity, and the cigarette frames of each round are successively placed in the stockpiling and humidifying warehouse for humidification;

[0112] In S2015, according to the quantity of cigarette frame grades required for each feeding round and the storage location situation of the humidifying and stockpiling warehouse, a "Material Requisition Sheet for the Humidifying and Stockpiling Warehouse" is generated and pushed to the raw tobacco storage warehouse management system;

[0113] In S2016, a storage location plan for the humidifying warehouse is carried out, a "Warehouse Receipt for the Humidifying and Stockpiling Warehouse" is generated and pushed to the "Inventory Management System for the Stockpiling and Humidifying Warehouse" for inbound transportation through AGV scheduling, or it can also be put into storage manually.

[0114] The storage location planning rules are as follows: according to the principle of inbound on the same day, humidifying at night, outbound the next day, and recycling of storage locations, storage locations are allocated. And according to the production feeding sequence and the principle of prior processing of small modules, a reverse calculation is carried out. The tobacco leaves are processed in the order of last - in - first - out, and the same - grade and same - module tobacco leaves are stored nearby. Small modules are preferably placed near the outbound port; for small grades that require "grading and stacking", they are stacked nearby for manual mixing to make the weight and grade composition of each cigarette frame the same after stacking.

[0115] In S202, according to the production arrangement, calculate the feeding quantity required for each round of the day, generate an outbound plan for the humidifying warehouse, calculate the material outbound plan for the stockpiling and humidifying warehouse and the uniform distribution plan of tobacco leaves on the laying line according to the tobacco leaf grades, quality ratio, and blending requirements, and allocate the tobacco leaves to the corresponding workstations on the laying line;

[0116] The material outbound plan for the stockpiling and humidifying warehouse and the uniform distribution plan of tobacco leaves on the laying line include the following steps:

[0117] In 2021, during the leaf laying process, while feeding the leaves, the next round of preparation is carried out simultaneously. After the feeding is completed, the feeding and preparation methods are switched to ensure the continuity and high efficiency of production. According to the number of grades and the number of small modules, the leaf laying line feeding mode is selected, which is divided into the following situations:

[0118] 1) Single-grade feeding and preparation: When the number of grades is 1, no small module splitting is performed, and no grade blending is carried out. The leaf laying and feeding are carried out at 10 positions on one side of a single leaf laying line, and the next round of preparation is carried out simultaneously on the other side (e.g., feeding on side 1-a of the leaf laying line and preparing on side 1-b of the leaf laying line). There is no blending relationship between each position, and the leaves are directly fed and packed until the end of the grade.

[0119] 2) Batch-by-batch single-line feeding and preparation: When the number of split small modules is 1 and the number of grades in the small module ≤ 10, 10 positions on one side of a single leaf laying line are used for leaf laying and feeding, and the next round of preparation is carried out simultaneously on the other side (e.g., feeding on side 1-a of the leaf laying line and preparing on side 1-b of the leaf laying line). All grades of the full formula are fed through a single leaf laying line. Each leaf laying line contains the complete formula grades. The tobacco leaves of the same batch enter the same packing station. Four lines can be used simultaneously for leaf laying and feeding of 4 batches.

[0120] 3) Batch-by-batch multi-line feeding and preparation: When the number of split small modules is 1 and 10 < the number of grades in the small module ≤ 20, two leaf laying lines are used for combined feeding. One leaf laying line with 20 positions on both sides is used for leaf laying and feeding, and the other leaf laying line with 20 positions on both sides is used for the next round of preparation (e.g., feeding on side 1-a of the leaf laying line and side 2-b of the leaf laying line, and preparing on side 1-b of the leaf laying line + side 2-a of the leaf laying line). All grades of the full formula are fed through two leaf laying lines. The tobacco leaves of up to 20 grades in the same batch are blended and then all enter a single packing station. Two batches of leaf laying and feeding can be carried out simultaneously.

[0121] 4) Feeding by small module combined blending: When the number of split small modules > 1 and the number of grades in the small module ≤ 10, according to the module splitting results, the grade blending of the tobacco leaves of each module is carried out on the leaf laying line. When leaving the warehouse, according to the proportion of the grades of the tobacco leaves in each module, they are matched and shipped out to form a complete batch.

[0122] 5) Full-position (micro-module) feeding: For example, if the number of grades in a certain small module > 10, when 10 ≤ the number of grades in the micro-module ≤ 20, one leaf laying line with 20 work positions is used for one-time preparation and feeding. When 20 ≤ the number of grades in the micro-module ≤ 40, two leaf laying lines with 40 work positions are used for one-time preparation and feeding. Feeding is carried out in multiple rounds according to the production batches, and the next round of preparation is carried out only after all the feeding is completed, realizing the function that the tobacco leaves of up to 40 grades are blended and then all enter a single packing station.

[0123] In S2022, according to the feeding mode of the leaf-laying line, following the principle of single-line grade crossing and multi-line grade equalization, that is, the same-grade tobacco leaves are not adjacent on the same leaf-laying line station, and the same large grade is evenly distributed on different leaf-laying lines. Select the optimal allocation method, generate the "leaf bundle plan" through calculation, and the feeding combination method and blending information of different grades of tobacco leaves for each batch on each leaf-laying line, including tobacco leaf variety, grade, and total number of frames.

[0124] In S2023, according to the total feeding amount and the information of the storage positions in the preparation humidification warehouse, generate the "feeding round plan" and the "preparation plan". The "feeding round plan" includes the variety, grade, nicotine, feeding amount, feeding rate, and feeding station of the tobacco leaves that need to be fed on each leaf-laying line for each round; the "preparation plan" includes the variety, grade, nicotine, number of frames for preparation, and storage position number in the humidification warehouse required for the tobacco leaves for each round of feeding;

[0125] In S203, according to the total feeding weight and the number of boxes required for the production of each batch of tobacco leaves, the measurement value and process requirements before the tobacco leaves enter the packing station, calculate the number of boxes for each batch and the loading amount per box, and perform automatic packing;

[0126] The calculation process of the number of boxes for each batch and the loading amount per box is as follows:

[0127] In S2031, set the loading amount per box ≤ 350 kg / box according to the volume of the tobacco boxes in the high-rise warehouse, and the total weight of the batch of tobacco leaves is 12000 kg / h;

[0128] In S2032, estimate the number of boxes for the batch = 12000 kg / h (total weight of the batch of tobacco leaves) ÷ 350 kg (loading amount per box) ≈ 34.28 boxes;

[0129] In S2033, round up the number of boxes to the nearest multiple of 6 according to the number of the box-turning and discharging machines, then the actual number of boxes is 36 boxes, and inversely calculate the loading amount per box = 12000 kg / h (total weight of the batch of tobacco leaves) ÷ 36 boxes (actual number of boxes) = 333.3 kg / box;

[0130] If the low packing weight is caused by the fluffy tobacco leaves, the number of boxes is 42 boxes, and inversely calculate the loading amount per box = 12000 kg / h (total weight of the batch of tobacco leaves) ÷ 42 boxes (actual number of boxes) = 285.7 kg / box;

[0131] In S2034, the calculation methods for different feeding modes are as follows:

[0132] 1) Packing of single-grade tobacco leaves: Loading amount per box = total weight of the batch of tobacco leaves ÷ number of boxes for the batch;

[0133] 2) Packing by batch blending: Loading amount per box = ∑(proportion of small-grade weight × total weight of the batch of tobacco leaves) ÷ number of boxes for the batch;

[0134] 3) Pre - mix and pack in small modules: The number of boxes packed in a batch is equal to the total number of boxes packed with all small modules.

[0135] The number of boxes packed with small modules = (Ratio of small modules ÷ 6) × Number of boxes packed in a batch.

[0136] The single - box loading capacity of small modules = (∑ Proportion of weights of each grade contained in small modules × Total weight of tobacco leaves in a batch) ÷ Number of boxes packed with small modules.

[0137] S204. After calibrating relevant information such as weight, grade, chemical composition, batch number, box number, etc. for qualified tobacco boxes, they are put into the high - rack warehouse.

[0138] S205. According to the blending plan and homogenization requirements, perform homogenization single - batch out - warehouse calculation based on blending requirements, grade information, chemical information, weight information, and formula, generate multiple optional and optimal homogenization control schemes, reasonably plan the collocation order of out - warehouse tobacco boxes, and allocate them to the turning - box feeding machine to achieve automatic formula grouping and homogenization out - warehouse production of threshed and redried raw tobacco. The out - warehouse methods include single - grade tobacco leaf out - warehouse, batch - mixed out - warehouse, small - module combination - mixed out - warehouse, and direct out - warehouse of raw tobacco by single grade. Tobacco boxes in the high - rack warehouse follow the principle of first - in - first - out and are preferentially selected according to the set storage time.

[0139] The homogenization calculation method for the out - warehouse method includes

[0140] S2051. Taking the tobacco boxes in the high - rack warehouse as the basic out - warehouse unit, the total number of out - warehouse tobacco boxes is equal to the number of boxes packed in a batch. The out - warehouse tobacco boxes are allocated to the corresponding turning - box and discharging machine channels for feeding. The number of activated turning - box and discharging machines is selected according to the number of modules. There are the following situations.

[0141] 1) For single - grade tobacco leaf out - warehouse and batch - mixed out - warehouse, after selecting out - warehouse tobacco boxes from all the tobacco boxes in the module, they are evenly distributed to N turning - box and discharging machines for blending and feeding.

[0142] 2) For small - module combination - mixed packing, first calculate the required out - warehouse tobacco boxes for each small module according to the ratio of small modules, select from the corresponding tobacco boxes of each small module, and different small modules are allocated to different turning - box and discharging machines for blending and feeding.

[0143] 3) For direct out - warehouse of raw tobacco by single grade, it does not enter the high - rack warehouse and is directly fed through cross - docking.

[0144] S2052. The out - warehouse tobacco boxes are selected according to the requirement of chemical value balance. The basis is to perform comprehensive calculation on multiple indicators such as nicotine, reducing sugar, total sugar, total nitrogen, potassium, chlorine, color, sugar - alkali ratio, two - sugar ratio, etc. according to their respective weights.

[0145] 1) Inter - batch balance: The average chemical values of all tobacco boxes between each out - warehouse batch are balanced.

[0146] The average chemical value X = ∑ chemical values of cigarette boxes ÷ number of boxes packed in a batch,

[0147] For each batch, based on X, select appropriate cigarette boxes according to the number of boxes packed in the batch, so that the average chemical value X of the batch is approximately equal to the average total chemical value X.

[0148] 2) Intra-batch balance: For the same batch, balance the tobacco leaf chemical values among the groups for outbound shipment

[0149] The number of outbound groups = the number of boxes packed in a batch ÷ the number of reclaimer machines,

[0150] Calculations can be performed according to the principles of ascending, descending, and equal distribution of chemical values among groups. After manually previewing the outbound queue, select a better method for outbound shipment;

[0151] S2053, the system automatically calculates the feeding rate ratio of each reclaimer machine. The reclaimer machine controls the flow of the electronic scale according to this ratio for uniform feeding, so as to achieve proportional blending of tobacco leaves within the group. The calculation method is as follows,

[0152] V 通道1 : V 通道2 :...: V 通道n =

[0153] ∑ 通道1投料总量 : ∑ 通道2投料总量 :...: ∑ 通道n投料总量 .

[0154] The homogenization outbound methods are divided into two types: static outbound and dynamic outbound. When the total quantity of the matching order form can all enter the high-rise warehouse, select the static outbound method to generate all outbound queues at one time; dynamic outbound is applicable to the situation where the total quantity of the matching order form is large and the capacity of the high-rise warehouse is insufficient. When the total quantity of the matching order form cannot all enter the high-rise warehouse, as long as the entire formula enters the warehouse at one time, dynamic outbound can be started.
