[0046] In order to enable persons skilled in the art to better understand the solutions of the embodiments of the present invention, the embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings and implementation modes.

[0047] In the existing production process based on tobacco materials, the total quantity of materials is usually estimated according to the total quantity of expected tobacco products, so that the tobacco materials are directly transferred to the production line. However, directly estimating the total quantity of materials is prone to over-scheduling or under-scheduling, which greatly affects the production speed of tobacco products and easily causes the problem of low quality of tobacco products. The embodiment of the present invention provides a material scheduling method for tobacco materials, such as Figure 1 As shown, the method includes:

[0048] 101. Obtain the material categories and product production information for tobacco products.

[0049] In the embodiment of the present invention, the current execution subject is a main control computer or server that monitors and controls tobacco material production equipment. In order to accurately control the material transmission equipment to perform scheduling operations, the production line to be scheduled for materials, the product production information of the tobacco products currently being produced, and the material categories of the materials currently in use are monitored in real time. For example, the tobacco drying operation has been completed and the tobacco shred processing operation is about to begin. At this time, the material category includes tobacco shreds; or, the tobacco processing operation has been completed and the rolling process is about to begin. At this time, the material category includes tobacco shreds, cigarette paper, and cigarette holders. Product production information includes both basic information about the tobacco products currently being produced, such as tobacco type, production type, etc., and progress information about tobacco product production, such as current operating equipment, process flow nodes, etc., which is not specifically limited in the embodiment of the present invention.

[0050] 102. Determine target equipment and process information for expected production of the tobacco product on a production line based on the product production information.

[0051] In the embodiment of the present invention, the production process of tobacco products involves multiple production equipment, and each production equipment may include at least one processing equipment node and at least one material operation object for operating materials. Among them, each processing equipment node may be the same work station or different flow work stations. For example, the cigarette equipment may include a cigarette paper taking mechanical arm, a tobacco shred delivery mechanical arm, and multiple cigarette operation mechanical arms, each of which is a material operation object. Since the equipment applied to different types of tobacco products is different, that is, the process information, the process equipment and production process flow applied in different production processes are also different during the operation of the production line. Therefore, the target equipment expected to be applied can be determined according to the tobacco type before the production starts, and the next processing equipment node can be determined according to the current product production information and the complete process production flow during the operation of the production line, and then the production process to be carried out and the target equipment for executing the production process are determined.

[0052] It should be noted that by monitoring product production information and material categories, and taking the processing equipment and process operation stations on the production line as the smallest monitoring unit, accurate and real-time monitoring of materials can be achieved, thereby ensuring the accuracy and timeliness of material monitoring.

[0053] 103. Determine the material loss coefficient corresponding to the target equipment and the process information, and determine the target material information corresponding to the processing equipment nodes of different target equipment based on the material loss coefficient and the product production information.

[0054] In the embodiment of the present invention, during the execution of the processing equipment node of the target equipment and the production process flow, it is inevitable that tobacco material will be lost, such as tobacco falling, cigarette paper damage, cigarette holder damage, etc. Under the condition of stable production, the materials lost by each equipment and process flow are relatively stable. Therefore, the material loss data corresponding to each equipment and process flow can be calculated through long-term process data statistics, that is, the material loss coefficient, and the material loss coefficient can be associated with the corresponding target equipment and production process flow, so as to further determine the material loss coefficient after determining the target equipment and process information. Among them, the material loss coefficient can be the proportion of the material lost at the current station to the material before processing at the current station, or it can be the proportion of the remaining material after the operation of the current station is completed to the material before processing at the current station, which is not specifically limited in the embodiment of the present invention. After determining the material loss coefficient corresponding to the processing equipment node of the target equipment, the expected loss of material can be calculated according to the material information and material loss coefficient of the current processing equipment node, and then the material quantity under the current material category expected to be required at the current processing equipment node is calculated, that is, the target material information.

[0055] 104. Determine material scheduling information allocated to different processing time nodes according to the material category and the target material information, and control material transmission equipment to perform scheduling operations on the production line according to the material scheduling information.

[0056] In the embodiment of the present invention, each processing equipment node corresponds to a processing time node. For example, in a complete production process, starting from the initial input time node, if the production line is operating normally, when the production reaches the A processing time node, the processing equipment node that is performing the production operation should be the a node corresponding to the A processing time node. After determining the target material information of different processing equipment nodes, the material state can be determined to be an excess state, a normal state, or a missing state, and the amount of excess or missing materials, etc., according to the material category and target material information of any processing equipment node, and then the material scheduling information of the corresponding processing time node is determined. Among them, the material scheduling information includes information such as scheduling time, scheduling order, scheduling position, scheduling material quantity, and material transmission equipment for executing scheduling. Among them, the material transmission equipment is the equipment responsible for material operation on the tobacco production line, such as handling equipment, vacuum handling equipment, sorting equipment, automatic navigation vehicle, automatic guided operation (AGV: Automated Guided Vehicle) vehicle, linear conveyor, etc., which is not specifically limited in the embodiment of the present invention.

[0057] It should be noted that by calculating the expected material loss of the processing equipment node operation according to the material loss coefficient of the equipment, it is possible to accurately calculate whether the current material can meet the production operation requirements of the expected target equipment and process, as well as the impact of the remaining material on the subsequent process after the target equipment is operated, and calculate the missing or surplus material in real time, thereby realizing timely and accurate scheduling of materials on the tobacco production line.

[0058] In an embodiment of the present invention, for further explanation and limitation, as Figure 2 As shown, before step 103 determines the target equipment and the material loss coefficient corresponding to the process information, the method further includes:

[0059] 201. Determine all process equipment and process information for the tobacco product to be produced.

[0060] 202. Obtain a material operation object of the process equipment, and determine an operation coefficient of the material operation object.

[0061] 203. Determine a material loss coefficient of each process equipment based on the operation coefficient and the process information.

[0062] In the embodiment of the present invention, the process equipment includes all the equipment on the tobacco production line, including material operation objects and other auxiliary process equipment (conveyor belts, assembly line tooling boards, etc.). Among them, the material operation object is the equipment for tobacco processing operations, such as cigarette robot arms, packaging equipment, packaging equipment, etc., which are not specifically limited in the embodiment of the present invention. The process information includes the number of processing steps, the duration of the processing steps, and the number of materials corresponding to different processing steps. The operation coefficient is used to characterize the utilization rate of the operation of tobacco materials. For example, a cigarette robot consumes 1,000 sheets of cigarette paper and rolls out 998 cigarettes. The operation coefficient of the cigarette robot, that is, the utilization rate of cigarette paper, is 99.8%. After determining the operation coefficient of the material operation object, the material loss coefficient of different process equipment can be determined by comprehensively considering the loss of material circulation, process defect rate, etc.

[0063] It should be noted that for an automated production line with a relatively mature process flow, the operating accuracy of its operating equipment is relatively stable. Pre-acquiring the operating coefficient of each material operating object and calculating the material loss coefficient of each process equipment can provide accurate data basis for the subsequent evaluation of the change of materials with production. Among them, the operating coefficient can be obtained through historical process data statistics, or it can be determined according to the operating accuracy of the equipment, and the embodiment of the present invention does not make specific limitations.

[0064] In one embodiment of the present invention, for further explanation and limitation, the step of determining the material loss coefficient of each process equipment based on the operation coefficient and the process information includes:

[0065] Classify the operation coefficient and the process information based on the material loss classification model for which model training has been completed to obtain a material loss classification result;

[0066] The material loss coefficient corresponding to the process equipment is configured for the material loss classification result based on a preset numerical ratio.

[0067] In an embodiment of the present invention, in order to more accurately determine the material loss coefficient, the operating coefficient and process information are classified and processed based on the trained material loss classification model to obtain the material loss classification result. Among them, the material loss classification result includes material severe loss classification, material general loss classification, material slight loss classification, and material no loss classification. The basic model of the material loss classification model can be a support vector machine (SVM: Support vector machines) network, or a random forest model, etc., which is not specifically limited in the embodiment of the present invention. The training sample can be a sample marked with a loss classification label constructed based on the historical process information and operating coefficients of all production lines of the current tobacco production enterprise, and the loss function can be a cross entropy function or a random gradient descent function, which is not specifically limited in the embodiment of the present invention. After the material loss classification result of the current process equipment is predicted based on the material loss classification model, the corresponding preset numerical ratio is configured for the material loss classification result according to the preset numerical ratio as the material loss coefficient. Among them, the preset numerical ratio is a numerical ratio in the numerical range of 0-1. For example, the material severe loss classification corresponds to a preset numerical ratio of 5%, the material general loss classification corresponds to a preset numerical ratio of 1%, the material slight loss classification corresponds to a preset numerical ratio of 0.5%, and the material no loss classification is 0. It can also be customized according to the specific application scenario, and the embodiment of the present invention does not make specific limitations.

[0068] It should be noted that the material loss classification model that has completed model training is used to classify the operating coefficient and process information to obtain the material loss coefficient of the process equipment, thereby avoiding the situation where on-site process personnel configure the material loss coefficient based on experience values. The accuracy of the material loss coefficient depends on the experience level of the process personnel. This greatly improves the accuracy of the material loss coefficient, thereby providing a reliable data basis for the accuracy of material scheduling.

[0069] In one embodiment of the present invention, for further explanation and limitation, the step of determining the target material information corresponding to the processing equipment nodes of different target equipment based on the material loss coefficient and the product production information includes:

[0070] Based on a preset material loss calculation function, target material information at the processing equipment node corresponding to the material loss coefficient, the number of processing steps, the duration of the processing steps, and the different processing steps is determined.

[0071] In the embodiment of the present invention, the production process flow corresponding to each process equipment includes at least one processing step, and the number of processing steps corresponding to different process equipment and the total duration of the processing steps are different. Generally speaking, the more complex the processing steps and the longer the total duration of the processing steps, the greater the material loss. According to the statistical summary of actual production experience, the material loss of process equipment with the number of processing steps greater than or equal to 10 steps and the total processing time greater than or equal to 15 hours is significantly greater than that of other process equipment. Therefore, the preset material loss calculation function is:

[0072] ;

[0073] Among them, s is the number of processing steps, h is the total processing time, Q is the number of materials corresponding to different processing steps, and l is the material loss coefficient. Based on the preset material loss calculation function, the material loss of process equipment with different processing steps and different processing times can be calculated separately, thereby effectively improving the accuracy of material loss calculation and providing accurate material data for material scheduling.

[0074] In one embodiment of the present invention, for further explanation and limitation, the step of determining the material scheduling information assigned to different processing time nodes according to the material category and the target material information, and controlling the material transmission equipment to perform scheduling operations on the production line according to the material scheduling information includes:

[0075] If the processing time node matches the processing equipment node, the material scheduling information corresponding to the material category and the target material information is determined according to a preset material scheduling mapping relationship;

[0076] If the processing time node does not match the processing equipment node, a scheduling alarm message is generated to instruct to check the processing time node.

[0077] In an embodiment of the present invention, in order to ensure the accuracy of material scheduling, before determining the material scheduling information, the matching between the processing time node and the processing equipment node is verified. For example, the current processing time node is 12:58, and the corresponding processing equipment node should be the start of the baking equipment according to the process flow. If it is detected that the current processing equipment node is the heating of the baking furnace of the baking equipment, it indicates that the processing time node matches the processing equipment node, and the material scheduling information can be further determined. If it is detected that the current processing equipment node is not the baking equipment, but the tobacco delivery robot arm is operating, it indicates that the processing time node does not match the processing equipment node, and it is necessary to dispatch an alarm information to instruct the on-site inspection personnel to check the processing time node to determine whether the equipment operation is abnormal.

[0078] Among them, the preset material scheduling mapping relationship stores material scheduling information corresponding to different material categories and different material information. The material scheduling information is used to characterize at least one of the scheduling time, scheduling order, scheduling location, and scheduling method information for scheduling operations on tobacco materials on the production line. Among them, the scheduling time can be immediate scheduling or scheduling after a preset interval time. The scheduling time can be associated with the start-up time of the target device corresponding to the material information. For example, it takes a long time of circulation or static from the current production stage to the start-up of the target device, and the corresponding scheduling time can be scheduling after a preset time interval; if the time interval from the current production stage to the start-up of the target device is short, the corresponding scheduling time can be immediate scheduling. The scheduling order can be the priority of scheduling. For example, the material information indicates that the scheduling priority corresponding to the missing material is higher than the priority of the excess material; the scheduling priority corresponding to the material with a longer material category scheduling time or a longer scheduling distance is higher than the material with a shorter material category scheduling time or a shorter scheduling distance. The dispatching position includes the material picking position and the material loading position. When the material is missing, the material picking position corresponds to the material category, and the material loading position corresponds to the processing equipment node. When the material is in excess, the material picking position corresponds to the processing equipment node, and the material loading position corresponds to the material category. The dispatching method information may include the material transportation tool (VGA trolley) used for dispatching, and the direction of material dispatching, for example, taking excess materials from the processing equipment node or replenishing materials to the processing equipment node.

[0079] In one embodiment of the present invention, for further explanation and limitation, the step of determining the target equipment and process information for the expected production of the tobacco product on the production line based on the product production information includes:

[0080] Parsing the tobacco type and production type in the product production information;

[0081] Perform startup verification on all equipment through the generation type and send a process information verification instruction;

[0082] After the startup verification and the process information verification are completed, the target equipment and process information for preset production are determined according to the tobacco type.

[0083] In the embodiment of the present invention, in order to ensure the quality and efficiency of production, it is necessary to verify whether all equipment can start and run normally according to the corresponding production type according to the production type in the product production information, so as to ensure that each device can complete the operation under the current generation type. Then, a process information verification instruction is sent to each device for automatic verification, or a process information verification instruction is sent to the inspection terminal for manual verification, so as to ensure that the corresponding process operation program is stored in each device, and the production of the corresponding process can be completed accurately according to the standard process flow. The tobacco type can be divided according to the different tobacco production process flow, or it can be divided according to the different materials used in the tobacco, the different packaging quantity, or the type of self-defined division according to the specific application scenario, which is not specifically limited in the embodiment of the present invention.

[0084] In one embodiment of the present invention, for further explanation and limitation, the method further includes:

[0085] When the scheduling operation is performed according to the material scheduling information, image detection information of tobacco materials at different target devices is collected in real time;

[0086] If the loss feature in the image detection information matches the preset alarm condition, the material scheduling missing information is sent to readjust the material scheduling information.

[0087] In the embodiment of the present invention, in order to ensure the accuracy of material scheduling, image detection information of tobacco materials at different target devices after material scheduling is collected in real time. Among them, the image detection information includes the image of the tobacco material at the target device, and the image acquisition frequency can be one frame per second, one frame per five seconds, or a custom frequency, which is not specifically limited in the embodiment of the present invention. The loss feature is a feature that can characterize the lack of material, for example, the distribution of tobacco shreds on the tooling in the image is uneven or there is a situation where there is no tobacco shreds in the local distribution, and the cigarette paper in the image is damaged. Loss feature matching can be based on the preset loss feature sample image and the image in the image detection information. It can also be feature extraction of local features in the image, and feature matching based on the extracted image features, that is, the preset alarm condition can be a loss feature sample image, or it can be a loss feature, which is not specifically limited in the embodiment of the present invention. When the preset alarm condition is met, the information of missing material scheduling is sent to the inspection terminal, so that the corresponding inspection personnel can understand that there is a scheduling missing in the current material scheduling, so as to trigger the readjustment of the material scheduling information in an automatic or manual manner. By performing image detection on tobacco materials at the target equipment during the material scheduling process, material scheduling errors can be discovered in a timely manner, and material scheduling information can be adjusted in a timely manner, thereby further ensuring the accuracy of material scheduling.

[0088] It can be seen that the present invention provides a material scheduling method for tobacco materials. The embodiment of the present invention obtains the material category and product production information of tobacco products; determines the target equipment and process information on which the tobacco products are expected to be produced on the production line based on the product production information; determines the material loss coefficient corresponding to the target equipment and the process information, and determines the target material information corresponding to the processing equipment nodes of different target equipment based on the material loss coefficient and the product production information; determines the material scheduling information allocated to different processing time nodes according to the material category and the target material information, and controls the material transmission equipment to perform scheduling operations on the production line according to the material scheduling information, calculates the material loss based on the material loss coefficient of each equipment, and uses the processing time node of the equipment as the minimum unit of material scheduling, thereby greatly improving the accuracy and precision of material scheduling, effectively avoiding the situation of excess or missing material scheduling, thereby effectively improving the production speed of tobacco products, and at the same time, ensuring the quality of tobacco products.
