Description

Technical Field

[0001] The invention belongs to the technical field of tobacco quality evaluation, and in particular relates to a batch-based shredded tobacco just-in-time production evaluation method and system. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] After the tobacco leaves enter the production line, they go through continuous processing such as unpacking, loosening and rehydration, adding materials and rehydration, and then enter the leaf storage cabinet for fermentation to balance the moisture. After that, they go through multiple processes such as shredding, drying, blending, and flavoring to form qualified tobacco. The leaf making process from raw material input to the output of finished tobacco is a segmented, multi-step, continuous processing process; the production process within the segment is stable and continuous, and the production between segments has a certain degree of adjustability.

[0004] In the whole process of cigarette processing, the silk-making process is very critical. Its process flow is relatively complex and very long, and there are many types of process equipment. In the process of quality control of the entire cigarette silk-making process, the process quality of each process will affect the intrinsic quality of the cigarette product; the silk-making process quality needs to coordinate the process quality of each process, standardize and improve the quality of the cigarette silk-making process.

[0005] In the production management of production workshops of traditional cigarette manufacturing enterprises, there are problems such as slow production pace, low production efficiency and poor production punctuality. There is a lack of evaluation standards for the production efficiency of the production workshops' batch production mode of "continuous-intermittent-continuous-intermittent". Summary of the invention

[0006] To solve the above problems, the present invention proposes a batch-based tobacco just-in-time production evaluation method and system, which uses batches as the evaluation basis to collect and analyze all tobacco production management factors, objectively reflects the compactness of cigarette product production, and realizes just-in-time production management under the "continuous-intermittent-continuous-intermittent" production mode based on batches.

[0007] According to some embodiments, a first solution of the present invention provides a batch-based on-time production evaluation method for cut tobacco, using the following technical solution:

[0008] A batch-based on-time production evaluation method for cut tobacco, comprising:

[0009] Obtain the production batch of tobacco to be produced and the operating status of the production equipment;

[0010] Determine the production status determination node of the tobacco to be produced according to the acquired operation status of the production equipment;

[0011] Determine the on-time production evaluation criteria of different production batches of tobacco according to the obtained production status determination node and production batch of the tobacco to be produced;

[0012] According to the determined on-time production evaluation standard for cut tobacco, it is judged whether the cut tobacco to be produced in different production batches is produced on time, and the batch-based on-time production evaluation of cut tobacco is completed.

[0013] As a further technical limitation, in the process of obtaining production batches of tobacco to be produced, the production batches of tobacco to be produced are divided into continuous batches that do not require preheating and non-continuous batches that require preheating, according to whether the tobacco production host equipment needs to be preheated.

[0014] Furthermore, if the interval between the production time and the previous batch of production is short, the main tobacco production equipment does not need to be reheated, then the production batch is a continuous batch; if the interval between the production time and the previous batch of production is long, the main tobacco production equipment needs to be reheated after cooling, then the production batch is a non-continuous batch.

[0015] Furthermore, the evaluation standard for on-time production of continuous batches of tobacco is the batch change time, that is, the time from the end of the material of the main machine of the previous batch to the state of the main machine of the current batch changing to the start of production is within the specified time.

[0016] Furthermore, the evaluation criteria for on-time production of non-continuous batches of tobacco are divided into two dimensions, namely, the difference between the planned preheating time and the actual preheating time, and whether the equipment waiting time is within the specified waiting time.

[0017] As a further technical limitation, the determined production status judgment nodes of the tobacco to be produced at least include preheating, waiting for material, production and finishing.

[0043] Embodiment 1

[0044] Embodiment 1 of the present invention introduces a batch-based on-time production evaluation method for cut tobacco.

[0045] like Figure 1 A batch-based tobacco production evaluation method is shown, comprising:

[0046] Obtain the production batch of tobacco to be produced and the operating status of the production equipment;

[0047] Determine the production status determination node of the tobacco to be produced according to the acquired operation status of the production equipment;

[0048] Determine the on-time production evaluation criteria of different production batches of tobacco according to the obtained production status determination node and production batch of the tobacco to be produced;

[0049] According to the determined on-time production evaluation standard for cut tobacco, it is judged whether the cut tobacco to be produced in different production batches is produced on time, and the batch-based on-time production evaluation of cut tobacco is completed.

[0050] like Figure 2 As shown, this embodiment uses electronic belt scales and other sensing devices, field controllers, data acquisition systems, tobacco production management systems and production management systems to achieve full collection and analysis of production management elements such as production plans, production rhythms, host equipment, upstream and downstream processes, and process conditions, objectively reflect the compactness of cigarette product production, and achieve just-in-time production management for cigarette manufacturers in the "continuous-intermittent-continuous-intermittent" production mode based on batches; it solves the problem of lack of evaluation standards for tobacco production punctuality and unscientific and unreasonable production management.

[0051] This embodiment classifies and evaluates the production of different batches of tobacco according to the production characteristics of tobacco shreds, and determines the production status of tobacco shreds in combination with the operating status of the production equipment.

[0052] In this embodiment, according to the characteristics of tobacco production batches of "continuous-intermittent-continuous-intermittent", each production batch is divided into continuous batches and non-continuous batches according to whether the host equipment needs to be preheated:

[0053] (1) Continuous batch

[0054] The production time of this batch is short compared to the previous production batch at this position, so the equipment does not need to be preheated again.

[0055] (2) Non-continuous batches

[0056] The production time of this batch is relatively long compared with the previous production time of this post, and the equipment needs to be cooled and reheated.

[0057] In this embodiment, attention is paid to the equipment operation status, and the equipment status such as preheating, waiting for materials, production, and finishing is used as the production status determination node; specifically:

[0058] (1) Preheating

[0059] Preheating is a pre-production preparation for the host device to ensure the stability of the internal environment. Preheating indicates that the device has entered the stage of preparing for production.

[0060] (2) Waiting for materials

[0061] Waiting for materials means that the host equipment has met the production conditions and can start production at any time. This state will cause energy waste. According to lean management requirements, the shorter the waiting for materials state lasts, the better.

[0062] (3) Production

[0063] The production status refers to the state of normal operation of the equipment. This state is generally characterized by the material flow and cumulative amount of the electronic belt scale in front of the main machine reaching the specified values. That is, greater than the specified value indicates the start of production, and less than the specified value indicates the end of production.

[0064] (4) Closing

[0065] The finishing stage is a state in which the host equipment outputs tailings, which is different from the normal production state because the amount of tailings is small and the internal environment of the host equipment is in an unstable state.

[0066] According to the production characteristics of each process section and the nature of the batch, formulate corresponding judgment standards; specifically:

[0067] (1) Production evaluation standards for continuous approval

[0068] The batch change time, that is, the time from the start of tailing of the previous batch of host equipment to the start of production of the current batch of scale host equipment, is within the specified time, which is an on-time production batch.

[0069] (2) Production evaluation standards for non-continuous approval

[0070] The evaluation criteria for on-time production of non-continuous batches are divided into two dimensions: the difference between the planned preheating time and the actual preheating time; and whether the equipment's waiting time for materials is within the specified waiting time.

[0071] It should be noted that a single process is considered to be produced on time if the host equipment completes the production status conversion within the specified time node, otherwise it is not produced on time; if all processes in the process section are produced on time, the batch in this process section is considered to be produced on time, otherwise it is not produced on time.

[0072] This embodiment calculates the on-time productivity of a process based on the ratio of the number of on-time production batches to the total number of production batches; specifically:

[0073] (1) Calculation of process on-time productivity

[0074]

[0075] (2) Calculation of on-time productivity of process section

[0076] The on-time production record of the process is "1", and the off-time production record is "0". If the on-time production condition of the process segment batch is that all processes in the process segment are produced on time, the on-time production record of the process segment is considered to be "1", otherwise the off-time production record is "0"; that is,

[0077] Just-in-time production in the process stage = Just-in-time production 工序1 Just-in-time production 工序2 U...Just in Time Production 工序i

[0078]

[0079] like Figure 3 and Figure 4 The batch-based tobacco just-in-time production evaluation method shown in the figure mainly includes:

[0080] (1) Production plan acquisition and decomposition

[0081] The production workshop obtains production tasks and scheduling information from MES, and decomposes the production tasks into real-time tasks for the corresponding production machines based on the information obtained; based on the standards for on-time production determination of different production brands of different machines maintained in the early stage, such as standard preheating time, standard idle time, etc., combined with the real-time tasks of the machine, a schedule for the advancement of the machine's current production tasks is formed. The schedule includes the theoretical execution schedule for each stage of machine production, which serves as the basis for determining the on-time production of the machine.

[0082] (2) Operation sequence generation and issuance

[0083] According to the steps that need to be operated on the machine at the job site, the operating sequence and theoretical time of the steps are specified; after the machine receives the production task and forms a promotion schedule, an operating rhythm is formed according to the operating sequence to guide the machine operator to perform standardized and accurate operations.

[0084] (3) Reminder function

[0085] Collect the progress of machine operation rhythm and set countdown reminders, that is, when a certain rhythm is about to end, trigger the operation reminder to avoid missing work; at the same time, when the status of the machine host equipment changes, such as when the equipment preheating is completed, trigger the reminder function to tighten the production rhythm.

[0086] (4) Just-in-time production accounting and display

[0087] According to the actual progress of machine production, graded just-in-time production accounting is carried out and multi-dimensional visual display is achieved.

[0088] This embodiment uses batches as the evaluation basis to conduct a comprehensive collection and analysis of tobacco production management factors, objectively reflects the compactness of cigarette product production, and realizes just-in-time production management under the "continuous-intermittent-continuous-intermittent" production mode based on batches; this embodiment clarifies the important nodes of each production promotion in the tobacco production process, provides a method for determining just-in-time production of tobacco, promotes the scientific nature of tobacco production management in cigarette enterprises, realizes the manageability, controllability, and evaluability of tobacco production management processes, eliminates waste, and improves overall operational efficiency.
