Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of tobacco production, more particularly, to a method and system for preventing errors in a process section of a tobacco primary processing line. BACKGROUND

[0002] With the increasing complexity of the production process in the tobacco industry, and the requirement for flexibility and fine processing, the requirement for informationization, automation and fine processing of the primary processing line in the tobacco industry is becoming higher and higher, which makes the setting of the equipment operation parameters and the process parameters more and more complex. As the centralized monitoring system for the command and control center of the primary processing line production activities, the centralized monitoring system needs to complete the functions of centralized control operation, monitoring, production process data acquisition, formula management, alarm display, recording, etc. Meanwhile, the centralized monitoring system needs to accept the production management information from the production management system and provide various data and state information required for analysis and statistics for the production management system.

[0003] As the operator of the centralized monitoring system of the primary processing line, the operator needs to monitor the operation data of the production line at all times and also needs to perform a large amount of operation of the equipment parameters and the process parameters. Such manual operation is prone to misoperation under the high-pressure and high-intensity working environment in the central control room. Once misoperation occurs in important process parameters such as the selection of the in-cabinet and out-cabinet, the feeding ratio, the blending ratio, the cut tobacco moisture and temperature, etc., a significant quality accident and irreparable economic loss will be caused. How to prevent misoperation in the production process, which is a serious hidden danger, is a difficult problem that needs to be solved in the actual operation of the primary processing line management and control system.

[0004] Prior art and defects

[0005] At present, the centralized control system in the primary processing workshop is divided into 9 process sections according to the control function, among which the vacuum conditioning section, the dust removal and odor removal are locally operated, the leaf conditioning and the second leaf feeding are operated by 1 operator, the cut tobacco processing, the blending and the flavoring are operated by 1 operator, and the stem processing and the cut stem processing are operated by 1 operator. Each operator is equipped with two client computers for control.

[0006] The central control operator is responsible for the work order scheduling of the process section, the start and end of the batch, the automatic start of operation, the selection of the in-cabinet and out-cabinet, the input of the corresponding equipment process parameters of different brands, the adjustment of the control parameters in the process, etc. A large number of complex manual operations are prone to errors, which cannot be avoided, and the main manifestations are as follows:

[0007] 1. Selection error of complex process path and production mode

[0008] According to the requirements of the processing technology of each brand, Hulunbeier series, Xiaoshenmao series and Hongtashan series use vacuum moisture regain path, and other brands use slicing path for processing; Hongtashan series adopts conventional water adding in loose moisture regain process, and the slices are mixed before one-time feeding, water is added in one-time feeding, and feeding is added in two-time feeding; all other brands are loose moisture regain constant water adding, the slices are mixed before one-time feeding, one-time feeding is added, and water is added in two-time feeding; there are two kinds of entering pre-arrangement cabinet and not entering pre-arrangement cabinet for blade entering cabinet; two gang cut tobacco blending electronic scales (size ratio) are selected; and four selections of forward and reverse rotation of two belt conveyors entering the cabinet after adding flavor are provided. These process paths and production modes need the central control operator to select according to the process and actual situation before production, and once the operation is wrong, it will cause serious quality accidents and safety hazards.

[0009] 2. A large number of formula parameter input errors of different brands

[0010] According to statistics, there are 142 formula parameters in the 7 process sections of the central control operation which need to be manually input or checked and compared before production of different brands.

[0011] 3. Risk of process linking process

[0012] The process linking error prevention system mainly aims at the tracking and comparison of material information between the leaves pretreatment before the primary processing of the primary processing process and the finished product storage cabinet after the primary processing. In the primary processing process, the material always comes from a starting point (source) through certain process paths (processing units) and then enters another terminal (destination). These process paths are sometimes within the same PLC control range, and sometimes cross two or more PLC control ranges. For the production tasks within the same PLC control range, we call it the production process section task, and for the production tasks across the PLC, we call it the production process section task.

[0013] 4. Risk of conformity of material transfer between primary processing line and high-bay warehouse

[0014] The production plan of the day is issued to the primary processing technologist account, and the primary processing technologist simultaneously issues it to the primary processing central control and logistics ERP accounts. After checking and comparing, the logistics accepts the material signal from the primary processing and starts to discharge the material. The consistency of the brand and batch is checked by the primary processing material feeding worker during the discharging process, so the risk of wrong brand and mixed brand is very low. However, since the tobacco packages are continuously discharged on the logistics track, and the equipment is continuously running, there is a risk of error in the actual number of tobacco packages in each batch.

[0015] Therefore, how to provide a primary processing line process section error prevention control method and system becomes a technical problem to be solved in the field. SUMMARY

[0079] In step S5, after the silk production and the logistics handover, the number of cigarette packs in each batch is counted by the silk production system, thereby preventing errors in the handover with the logistics elevated warehouse.

[0080] In step S1, the IDs of various cards are counted, and the process path selection is prevented from errors according to the correspondence between the IDs and the process paths.

[0081] In some embodiments, in the step S1, as shown in the flow chart, Figure 2 the correspondence between the IDs and the process paths comprises:

[0082] The leaf wire grade of A is 1, the corresponding ID is 1, and the corresponding process path is pre-blending of thin sheet feed, vacuum rehydration path and small proportion of stem wire scale.

[0086] E's leaf line grade is 8, the corresponding ID is 19, and the corresponding process path is pre-blending of thin sheet feed, slicing path and small proportion of stem wire weighing.

[0087] The blade line designation of F is 9, the corresponding ID is 21, and the corresponding process path is;

[0091] J's leaf line grade is 16, corresponding to ID 29, and the corresponding process path is pre-blending of thin sheet feed, slicing path and large proportion of stem wire weighing.

[0092] K's leaf line grade is 18, corresponding to ID 31, and the corresponding process path is pre-blending and vacuum rehydration.

[0093] L's leaf line grade is 20, the corresponding ID is 34, and the corresponding process path is thin sheet feeding followed by blending, vacuum rehydration path and large proportion of stem and fiber scale.

[0095] The leaf line grade of N is 22, the corresponding ID is 36, and the corresponding process path is pre-blending before flake feeding, slicing path, and large proportion of stem and fiber weighing.

[0096] In some embodiments, the selection of the leaflet pre-assembly and the storage of the leaflets is directly locked to the pre-assembly according to the production practice, the feeding operation of the 16 groups of storage cabinets is optimized in the PLC program, and the selection operation is shielded to make the target of the selected cabinet correspond to the actual cabinet number.

[0097] In step S2, the material information is transferred from the source to the destination without being changed in the process of transfer, realizing error prevention within the process section.

[0098] In some embodiments, in the step S2, the method for transferring the material information from the source to the destination without being changed in the process of transfer, realizing error prevention within the process section, comprises:

[0099] By comparing the batch and the grade information of the material storage cabinet, error prevention within the process section is realized.

[0100] By interlocking the feeding and discharging actions of the material storage cabinet and judging the storage state of the cabinet, error prevention within the process section is realized.

[0101] Specifically, the consistency between the source and the destination of the material determines whether the task can be executed on the processing unit. The control concept of task-driven equipment will make the material information be tracked at different levels in the entire production process. The task issuing and batch running will transfer the material information from the source to the destination, but the information of the material itself will not be changed in the process of transfer. Therefore, the tracking of the material at the processing unit level is the key to the design of error prevention within the section.

[0102] The method for realizing error prevention within the process section comprises:

[0103] By comparing the batch and the grade information of the material storage cabinet, error prevention within the process section is realized.

[0104] By interlocking the feeding and discharging actions of the material storage cabinet and judging the storage state of the cabinet, error prevention within the process section is realized.

[0105] In step S3, based on the comparison of the material information and the interlocking between the device states of the process sections, error prevention within the process section is realized.

[0106] In some embodiments, in the step S3, the method for realizing error prevention within the process section based on the comparison of the material information and the interlocking between the device states of the process sections comprises:

[0107] When the feeding and discharging conditions are met, the material storage cabinet is allowed to feed and discharge, realizing error prevention within the process section.

[0108] The feeding and discharging conditions comprise:

[0109] The batch conflict does not exist in the material storage cabinet;

[0110] The grade conflict does not exist in the material storage cabinet;

[0111] When the material storage cabinet is selected for feeding, the material storage cabinet information is not for discharging, or when the storage cabinet is selected for discharging, the material storage cabinet information is not for feeding.

[0112] Specifically, the error prevention between process sections is an extension based on the error prevention within the section. The information originally belonging to one PLC needs to be exchanged between two or more PLCs through communication, so that the PLCs complete the execution of the process task through collaborative control. The information comparison and other work originally completed on one PLC need to be completed collaboratively between several PLCs, but the key point of the error prevention design is still based on the interlocking between the material information comparison and the device state. The specific method is:

[0113] When the feeding and discharging conditions are met, the material storage cabinet feeding and discharging are allowed, and the error prevention within the process section is realized;

[0114] The feeding and discharging conditions include:

[0115] The batch conflict does not exist in the material storage cabinet;

[0116] The grade conflict does not exist in the material storage cabinet;

[0117] When the material storage cabinet is selected for feeding, the material storage cabinet information is not for discharging, or when the storage cabinet is selected for discharging, the material storage cabinet information is not for feeding.

[0118] In step S4, by writing and entering all parameters corresponding to all grades into the formula library in the production management system and establishing the formula library of the centralized control system, the device process parameter entry error prevention is realized.

[0119] In some embodiments, in the step S4, the method of realizing the device process parameter entry error prevention by writing and entering all parameters corresponding to all grades into the formula library in the production management system and establishing the formula library of the centralized control system includes:

[0120] By adding or modifying parameter points, all parameters corresponding to all grades are written and entered into the formula library in the production management system;

[0121] The formula library of the centralized control system is established, and the association between the formula library of the centralized control system and the formula library in the production management system is established;

[0122] A one-to-one correspondence relationship between the centralized control device process parameters and the formula library of the centralized control system is established; when a formula parameter download instruction is issued, the formula parameters are valued.

[0123] At step S5, after the tobacco processing and logistics interface, the tobacco processing system counts each batch of tobacco packets, and realizes error prevention during the interface with the logistics elevated warehouse.

[0124] In some embodiments, in the step S5, after the tobacco processing and logistics interface, the tobacco processing system counts each batch of tobacco packets, and realizes error prevention during the interface with the logistics elevated warehouse.

[0125] The tobacco processing system counts each batch of tobacco packets, and checks with the logistics out-of-warehouse cargo quantity, and after the check is correct, the next batch of materials is interfaced, realizing error prevention during the interface with the logistics elevated warehouse.

[0126] In summary, the scheme proposed in the application can simplify the operation process, avoid complex manual operation, and maximize the reduction of quality risks.

[0127] 1. Slice, vacuum conditioning two paths, thin slice blending before feeding, blending after feeding two paths, leaf into pre-blending, into storage two paths can be automatically selected according to the card. The 1-16 storage cabinet operation is directly performed, which is improved from the previous selection of group and then selection of cabinet to direct selection of cabinet.

[0128] 2. The storage information of 42 storage cabinets can be displayed in real time. When the batch production starts, the central control operator selects the tobacco processing out of the cabinet, and the system automatically judges and verifies whether the material card number in the current storage cabinet and the current process section production card number are the same. When they are the same, the system allows the storage cabinet to discharge; when they are not the same, the system gives a warning and prohibits the storage cabinet from discharging. At the same time, the central control monitoring operation interface automatically pops up an alarm window to prompt the operator to pay attention, thereby realizing the error prevention management function of the storage cabinet discharge.

[0129] 3. When the daily production plan is issued to the central control, the central control operator can select the corresponding equipment process parameters according to the production arrangement after selecting the corresponding card batch, which can be downloaded to the corresponding position, realizing the purpose of worry-free production.

[0130] The production plan operation sequence is: selecting batch card - downloading parameters - batch starting, which saves a lot of intermediate parameter input and checking work.

[0131] 4. The actual number of tobacco packets can be correctly displayed, and can be cleared after each batch is completed, and the next batch can be restarted.

[0132] When the displayed number of tobacco packets does not match the actual number, the central control operator communicates with the on-site personnel in time to prevent the phenomenon of batch error and batch mixing.

[0133] Achievements:

[0134] 1. To achieve effective integration of brand, production path and production mode within the work order, that is, the production path and production mode are automatically switched according to the process requirements of each brand, replacing the manual selection by the central control operator.

[0135] 2. Enable the automatic and accurate distribution of formula parameters for each brand as work orders are scheduled.

[0136] 3. Achieve effective integration of information flow and logistics, ensuring that the information of the material itself is always bound from the first process to the entry into the storage cabinet, thus eliminating the risk of mislabeling or mixing.

[0137] 4. Enable cross-departmental information supervision.

[0160] AN represents the code for each type / brand of cigarette.

[0161] According to the system of the second aspect of the present application, the second processing module 102 is specifically configured to: the material information is transferred from the source to the destination, and the material information is not changed in the transferring process, and the method for preventing errors in the process section comprises:

[0162] The batch comparison and the grade information comparison of the material storage cabinet are implemented to prevent errors in the process section.

[0163] The feeding and discharging action interlocking of the material storage cabinet and the storage state judgment of the cabinet are implemented to prevent errors in the process section.

[0164] Specifically, the consistency between the source and the destination of the material determines whether the task can be executed on the processing unit. The control concept of the task-driven device is adopted, so that the material information is tracked in a hierarchical manner in the entire production process. The task issuing and batch running transfer the material information from the source to the destination, but the information of the material itself will not be changed in the transferring process. Therefore, the tracking of the material at the processing unit level is the key to the design of the error prevention in the section.

[0165] The method for preventing errors in the process section comprises:

[0166] The batch comparison and the grade information comparison of the material storage cabinet are implemented to prevent errors in the process section.

[0170] The feeding and discharging conditions comprise:

[0171] There is no batch conflict in the material storage cabinet.

[0172] There is no grade conflict in the material storage cabinet.

[0173] When the material storage cabinet feeding is selected, the material storage cabinet information is not discharging, or when the cabinet discharging is selected, the material storage cabinet information is not feeding.

[0174] Specifically, the error prevention between process sections is extended on the basis of error prevention within a section. Information originally belonging to one PLC needs to be exchanged between two or more PLCs through communication to enable the PLCs to perform a process task through collaborative control. Information originally compared in one PLC needs to be compared between several PLCs, but the key point of error prevention design is still based on the interlocking between material information comparison and device state.

[0175] When the feeding and discharging conditions are met, the material storage tank is allowed to feed and discharge, thereby realizing error prevention within a process section.

[0176] The feeding and discharging conditions include:

[0177] There is no batch conflict in the material storage tank.

[0178] There is no grade conflict in the material storage tank.
