[0009] When feeding or discharging tobacco shreds into the storage cabinet, the system counts cells and determines the current cell stacking pattern based on the corresponding digital twin model to ascertain the material state within the storage cabinet. This allows the system to determine whether feeding or discharging is complete. If complete, the system controls the start or stop of the tobacco shreds storage cabinet.

[0010] Preferred options also include:

[0013] Get the number corresponding to the current cell. If the number of the current cell reaches the maximum number of the tobacco storage cabinet, then determine that feeding or discharging is complete.

[0014] Preferred options also include:

[0035] To enable those skilled in the art to better understand the embodiments of the present invention, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and implementation methods.

[0036] To address the issue that current cigarette production lines require operators to observe materials during the feeding and discharging of tobacco storage bins to determine the start and stop of the bins, this invention provides a material inflow and outflow control method for tobacco storage bins. This method solves the problem of existing methods requiring operator observation, which can lead to difficulties in timely control of the bins' start and stop during production. It improves the intelligence of material inflow and outflow control in tobacco storage bins and reduces energy consumption in production.

[0037] like Figure 1 As shown, a material inlet and outlet control method for a tobacco storage cabinet includes:

[0038] S1: Obtain the total material weight w of the fabric crane, the belt speed v1, the reciprocating speed v2 of the fabric crane, the distance s between the two ends of the tobacco storage tank, and calculate the total feeding time t. s And the time t1 required for the fabric crane to complete one movement.

[0039] S2: According to the formula: c2=t1, The values ​​of c1, c2, and w are calculated. i A cell-format digital twin model corresponding to the tobacco shreds storage tank feeder was established. The cell-format digital twin model has c2 cells for length and c1 cells for height, and each cell represents a material weight of w. i .

[0040] S3: Obtain the discharge time t3 of the tobacco storage tank and the discharge speed v3 of the bottom belt of the storage tank, according to the formula: The value of c3 is calculated, and a digital twin model of the unit format corresponding to the material discharge from the tobacco storage cabinet is established. The length of the digital twin model of the material discharge unit format is c3.

[0041] S4: When feeding or discharging tobacco into the tobacco storage cabinet, the system counts cells and determines the current cell stacking pattern based on the corresponding digital twin model to identify the material form inside the tobacco storage cabinet. This determines whether feeding or discharging is complete. If complete, the system controls the start or stop of the tobacco storage cabinet.

[0042] Specifically, the material is broken down into multiple small cells. The number of cells and their current stacking arrangement are calculated based on the total weight of material input from upstream processes and the conveyor belt speed. When material enters or exits the storage compartment, changes within the compartment trigger photocells on the side of the compartment. This initial signal activates the material's digital twin model, which then begins to change, reflecting the real-time status of the material on-site. The specific algorithm is shown below.

[0043] Material feeding into the storage compartment: When the material enters the compartment, the bottom belt of the compartment stops, and the fabric trolley reciprocates above the compartment while rotating the belt. This is determined by the following parameters: w, belt speed v1, fabric trolley reciprocating speed v2, and the distance s between the two ends of the tobacco storage compartment. The formula is then used to calculate the material feeding process. The total feeding time t was calculated. s According to the formula: Calculate the time t1 required for the fabric crane to complete one travel.

[0044] The materials inside the storage cabinet are displayed in a cell format. In the cell format digital twin model, the length cells are c2, the height cells are c1, and each cell represents a material weight of w. i The specific calculation method is as follows:

[0045] ;

[0046] c2=t1;

[0047] ;

[0048] Material discharge: Obtain the discharge time t3 of the tobacco storage tank and the discharge speed v3 of the bottom belt of the storage tank, according to the formula: The calculation yields c3, and a digital twin model of the unit format corresponding to the material discharge from the tobacco storage cabinet is established. The length of the digital twin model of the material discharge unit format is c3. Various parameters of the cells are calculated, which can map the current status of the material in the storage cabinet in real time, and the mathematical relationship between the inlet and outlet cells.

[0049] The method also includes: setting up a material trigger phototube in the tobacco storage cabinet; when material enters or exits the cabinet, triggering the corresponding unit format digital twin model according to the material triggering phototube's infeed trigger signal or outfeed trigger signal to map the material status in the tobacco storage cabinet in real time.

[0050] Furthermore, the step of counting cells and determining the current cell stacking pattern based on the corresponding cell format digital twin model to determine the material form in the tobacco storage cabinet, and then judging whether feeding or discharging is complete, includes:

[0051] Get the number corresponding to the current cell. If the number of the current cell reaches the maximum number of the tobacco storage cabinet, then determine that feeding or discharging is complete.

[0052] In practical applications, such as Figure 2As shown, when materials enter the cabinet, the relevant parameters of each cell are calculated based on the total weight of the materials to be added and the crane operating parameters. The cells are then arranged according to a set pattern. When materials fall into the cabinet, the cells begin counting, reflecting the material's entry status in real time. The same process applies to material exiting the cabinet. Based on the total amount of materials in the cabinet and the parameters of the cabinet's bottom strap, the cell parameters are calculated, and the cells are arranged according to set requirements. When materials begin to exit the cabinet, the cells begin counting, reflecting the material's exit status in real time. If the exit / exit speed needs to be changed during production, the current cell number is locked, and the maximum cell number is recalculated based on the remaining materials to be processed. The original maximum number is then updated, and the cells resume normal counting, reflecting the changes in the materials inside the cabinet.

[0053] The method also includes: when it is necessary to change the production rhythm during the production process, the corresponding cell number of the corresponding unit format digital twin model is updated by changing the speed v1 of the fabric trolley belt and the discharge speed v3 of the storage cabinet bottom belt.

[0054] Furthermore, the update of the cell number corresponding to the corresponding unit format digital twin model is implemented, including:

[0055] Update cell numbers using the following formula:

[0056]

[0057] Among them, t s 'Indicates the updated material number in the last cell, t i The material number corresponding to the moment the parameter was changed.

[0058] Furthermore, the establishment of a unit-format digital twin model corresponding to the tobacco storage tank feeder includes:

[0059] The cells are numbered sequentially from 1, increasing sequentially from the beginning to the end of adjacent rows. Each row contains c2 cells, and the last cell is numbered t. s .

[0060] In practical applications, cells are like Figure 3 Arrange the cells according to the pattern shown, and number the cells using existing cell parameters.

[0061] Furthermore, the establishment of a unit-format digital twin model corresponding to the discharge of tobacco from the storage tank includes:

[0062] Divide the tobacco storage cabinet into columns c3, with each column forming a cell. The cell numbers start from 1 and gradually increase until c3.

[0063] In practical applications, cells are like Figure 4 Arrange them according to the pattern shown.

[0064] The method also includes:

[0065] A display table is created, wherein the label of each cell in the display table corresponds to the cell number in the cell format digital twin model.

[0066] By mapping the display table to the cells of the cell-format digital twin model one-to-one, the color of the cells in the display table is changed during material feeding or discharging to represent the material entering or leaving the cabinet.

[0067] In practical applications, the feed display table can be as follows: Figure 5 As shown, the output display table can be as follows: Figure 6 As shown.

[0068] This invention provides a material inflow and outflow control method for tobacco storage cabinets. Regarding production rhythm control: a digital twin model of the tobacco material is established during production, enabling real-time monitoring of the material's form within the cabinet. Furthermore, it can accurately map the real-time weight of the material within the cabinet, allowing central control operators to precisely control the production rhythm of the upstream and downstream processes without needing to be physically present, thus ensuring a stable tobacco flow rate on the production line.

[0069] In terms of energy conservation in production: When the feeding and discharging of the storage tank are completed during production, there is no need for manual determination of the completion of the feeding and discharging process to stop the operation of the storage tank equipment. By establishing a digital twin model through the unit format algorithm, the feeding and discharging status can be automatically reflected in the first time, and the operation of the storage tank equipment can be stopped immediately, thereby achieving the purpose of energy conservation and consumption reduction.

[0070] It is evident that establishing a digital twin model of the tobacco material during the production process enables real-time monitoring of the material's form within the storage tank and accurately maps its real-time weight. This allows operators in the control room to precisely control the production rhythm of the upstream and downstream processes without needing to be physically present, ensuring a stable flow of tobacco on the production line. This addresses the issue of existing tobacco storage tanks requiring operator observation for material entry and exit, which can lead to delays in controlling the start and stop of the storage equipment during production. It also improves the intelligence of material entry and exit control in tobacco storage tanks and reduces energy consumption during production.

[0071] The structure, features, and effects of the present invention have been described in detail above with reference to the embodiments shown in the figures. The above description is only a preferred embodiment of the present invention, but the present invention is not limited to the scope of implementation shown in the figures. Any changes made in accordance with the concept of the present invention, or equivalent embodiments modified to have equivalent changes, shall be within the protection scope of the present invention as long as they do not exceed the spirit covered by the specification and figures.
