Description

Technical Field

[0001] The present invention relates to the technical field of shoe production, and in particular to a centralized control method for a flexible module shoe production line. Background Art

[0002] With the increasing diversity of shoe styles, the complexity of shoemaking processes for different shoe shapes and styles varies greatly. Traditional shoemaking methods struggle to establish unified process standards for different shoes, resulting in low production efficiency and inconsistent product quality.

[0003] At present, shoemaking production lines are mainly divided into large production lines, medium production lines and micro production lines according to the production scale and order requirements of the factory. Among them, the process equipment and proportion of personnel of large production lines and medium production lines are relatively fixed, and are only suitable for large-scale standardized shoe production. They cannot adapt to the production needs of multi-variety and small-batch non-standard shoes; while micro production lines are mainly designed for small-scale customized non-standard shoe production. Although equipment combinations can be flexibly configured according to specific needs, manual matching of process parameters is required, which is inefficient and prone to errors.

[0004] In addition, during the shoemaking process, the process parameters of each production line (such as machine cycle, temperature, pressure, needle detection sensitivity, glue formula, time, etc.) are recorded in paper documents or local systems in a scattered manner. There is a lack of unified management and sharing mechanisms, and sharing across equipment and production lines is difficult. This makes it impossible to quickly reuse existing process parameters when producing non-standard shoes of the same model. When the same shoe model is produced multiple times, the equipment needs to be repeatedly debugged, and the process reuse rate is low, affecting production efficiency, product quality and consistency of the manufacturing process. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a centralized control method for a flexible modular shoemaking production line, which not only achieves process standardization of shoemaking to meet the increasingly small-batch, multi-variety shoe production needs, but also enables intelligent management and optimization of the production process, thereby reducing production management costs and improving production efficiency, product quality, and consistency of manufacturing processes. The technical solution adopted is as follows: A centralized control method for a flexible modular shoemaking production line, characterized by comprising the following steps: S1. Establish a management and control platform to extract, store, analyze and process production data, and realize data transmission and sharing with the server or cloud; S2. Setting a current shoe production line, the shoe production line includes a centralized control module and multiple shoe making equipment modules, the control terminals of each shoe making equipment module are electrically connected to corresponding input and output terminals of the centralized control module, and the centralized control module of the shoe production line is communicatively connected to the management and control platform; S3. Analyze and mark the current shoe production line to indicate which model of shoes it is suitable for. When producing that model of shoes, obtain the shoemaking equipment module combination and process parameters of each shoemaking equipment module of the current shoe production line through the centralized control module. Then, upload this data to the server or cloud through the management control platform and add it to the equipment module library and production line combination library. S4. The management and control platform establishes a mapping relationship between the current shoe shape characteristics and various process parameters, and binds these process parameters to the corresponding shoemaking equipment modules, forming a standardized process package that associates the shoe shape characteristics, various process parameters, and shoemaking equipment modules. The standardized process package is then uploaded to the server or cloud and added to the equipment module library. S5. When a shoe production order is received, the shoe model is determined and entered into the management control platform. The management control platform retrieves the shoe production line for this shoe model from the device module library and production line combination library on the server or cloud, and performs the following steps according to different situations: S501. If the production line combination library contains a shoe production line for the model of shoes, the management control platform directly calls and displays the shoe production equipment module combination and standardized process package corresponding to the model of shoes; S502. If no shoemaking production line for the shoe model is found, the shoe model is decomposed based on its features, and then shoemaking equipment module combinations and standardized process packages are searched on a server or cloud based on the required process parameters. If a shoemaking equipment module combination or standardized process package that meets the requirements of the shoe model can be found, the closest shoemaking production line is called and the shoemaking equipment module or standardized process package that needs to be replaced is displayed. The workshop is then searched for replaceable shoemaking equipment modules that are idle in production, and a production line combination is performed. The resultant combination is then uploaded to the server or cloud and added to the production line combination library. S503: If no shoemaking production line for the shoe model is found, and no combination of all shoemaking equipment modules or standardized process packages that meet the requirements of the shoe model are found, then jump to step S2; S6. The management control platform automatically distributes the order quantity and the standardized process package for producing the shoes to the corresponding shoe production line through the network, guides the operators to perform production operations, and completes the production and packaging processes of the shoes of this model.

[0006] In the above-mentioned flexible module shoemaking production line centralized control method, in step S1, the management and control platform is used as a data collection distribution and equipment management center for development and operation and maintenance. The management and control platform can communicate data with each shoemaking equipment module through the centralized control module of each shoemaking production line to extract, save, analyze and process production data, and upload it to the server or cloud to realize data sharing, so that engineers and managers can view and call it at any time. Managers can also input control instructions to the management and control platform to realize remote control and remote monitoring of the centralized control modules of each shoemaking production line; in steps S2-S3, multiple shoemaking production lines are set up, and each shoemaking production line can adapt to the production of corresponding models of shoes respectively, and by analyzing the production process of the current shoemaking production line and modularizing the functions, it is subdivided into a functional module as much as possible to complete a single function. When producing this model of shoes, the centralized control module can control each shoemaking equipment module and realize the data transmission and reception between each shoemaking equipment module and the management and control platform; in step S3, by labeling each shoemaking production line, In step S4, a mapping relationship is established between various shoe-making features (such as the curvature of the last and the pattern of the sole) of non-standard shoes and various process parameters (such as the machine beat, glue formula, spraying pressure, and output of each equipment) formed by production to form a reusable parameter template, and the process parameters debugged by the engineer (such as "temperature 120°C / pressure 3MPa / time 45s" for a certain model of shoe) are bound to the corresponding equipment module to form a standardized process package, which provides data support for subsequent production. In step S5, when a production order for a certain non-standard shoe is received, the model of the non-standard shoe is first determined and the shoe model is input into the management control platform. The management control system will automatically match the optimal production line combination (such as "micro-production line A"). = Drying Module B + Forming Module C”), and then the management personnel will determine whether an existing shoe production line can be used for production: If the non-standard shoe model can be produced by an existing shoe production line, they will check whether there is a ready-made shoe production line in the workshop. If there is, it will be directly loaded for production. If not, the shoemaking equipment module combination that constitutes the shoe production line will be transferred and the shoemaking equipment modules of the idle shoe production lines in the workshop will be used to form the shoe production line. If there is no existing shoe production line available, the process analysis will be used to determine which equipment modules need to be combined to form a new shoe production line, and then the new production line will be loaded for production.In step S6, the management and control platform automatically distributes the order quantity and the standardized process package for producing the non-standard shoes to the corresponding shoe production line via the network. This allows for the rapid reuse of existing process parameters when producing the same model of non-standard shoes. This eliminates the need for repeated equipment commissioning when producing the same shoe type multiple times, resulting in a high process reuse rate. This enables intelligent management and optimization of the production process, significantly improving production efficiency and quality control.

[0007] As a preferred embodiment of the present invention, the shoemaking production line in step S2 includes four shoemaking equipment modules: an upper shaping module, a drying module, a molding module, and a finished product packaging module. These modules are arranged in order from front to back. This allows the shoemaking production line to automate the entire process from upper shaping, drying, molding, to finished product packaging. The above-mentioned upper shaping equipment module can adopt a double-hot and double-cold toe and heel integrated shaping machine, a pulling machine, a softening and shoe last lacing integrated machine, a hydraulic automatic shoe last machine or a pressure visual marking machine, etc.; the above-mentioned drying equipment module can adopt a dust-collecting manual rough shoe grinding machine, a double-layer sole and upper glue activation drying machine, an intelligent double-layer rotary infrared rotary drying machine or a double-layer sole and upper glue activation drying machine, etc.; the above-mentioned forming equipment module can adopt one or more of a single-station hydraulic full-range forming machine, a single-station closed heat setting machine or a single-station closed cold setting machine, etc.; the above-mentioned finished product packaging equipment module can adopt one or more of an intelligent pneumatic last picking machine, a conveyor-type needle detector or a shoe last return device, etc.; the above-mentioned centralized control module generally includes a controller and a data transceiver.

[0008] As a preferred embodiment of the present invention, in step S3, for a certain model of non-standard shoes with existing production records, the historical production records of the model of non-standard shoes are searched to obtain the shoemaking equipment module combination and the process parameters of each shoemaking equipment module for producing the model of non-standard shoes; for a certain model of newly customized non-standard shoes, through process analysis, the corresponding production line or new shoemaking equipment module combination is matched, and the process parameters of each shoemaking equipment module are debugged according to the various shoe shape characteristics of the model of non-standard shoes to obtain the shoemaking equipment module combination and the process parameters of each shoemaking equipment module of the current shoemaking production line.

[0009] As a preferred embodiment of the present invention, in step S4, after the standardized process package is formed, an engineer writes an SOP guidance document corresponding to the standardized process package, and then uploads the SOP guidance document to the server or cloud through the management control platform; in step S6, the management control platform will issue the SOP guidance document to guide operators to perform production operations according to the SOP guidance document.

[0010] As a preferred solution of the present invention, in step S6, during the production process of each shoemaking production line, the management and control platform can monitor in real time whether the process parameters of each shoemaking equipment module are abnormal, and promptly alarm when an abnormality occurs to achieve remote monitoring.

[0011] Compared with the prior art, the present invention has the following advantages: The centralized control method for a flexible modular shoemaking production line of the present invention can solve the problems existing in the existing shoemaking production process, such as inconsistent process standards, inflexible equipment combination, and decentralized production data management.
