Description

Technical Field

[0001] This invention relates to the fields of industrial design and intelligent manufacturing technology, specifically to a method, process management system, and apparatus for automatically generating process sheets for flexible container bags (FIBCs). Background Technology

[0002] Traditionally, the preparation of process sheets for FIBC (Flexible Intermediate Bulk Container) production relies on manual calculations or manual drawing using general-purpose drafting software (such as AutoCAD). Due to the diverse bag shapes (e.g., round, square, inner bags) and complex combinations of process elements (e.g., inlet / outlet ports, strap structures), process sheet preparation is inefficient, error-prone, and highly dependent on the experience of process engineers. Furthermore, the company's process data is often scattered across personal computers or paper documents, making effective reuse and management difficult. Additionally, internal cutting details can easily be leaked when confirming finished product designs with customers. Summary of the Invention

[0003] The purpose of this invention is to provide an automatic method and system for generating process sheets for bulk bags, aiming to solve the problems of low efficiency in process sheet production, inconvenient data management, and easy leakage of core technologies in the prior art. Technical solution

[0004] To achieve the above objectives, the present invention provides the following technical solution: An automatic generation system for container bag process sheets, characterized in that it includes a client and a server, the system adopts the .NET architecture and has a built-in local database; the system includes: Bag type selection module: It provides a preset database of FIBC (Flexible Intermediate Bulk Container) bag types and receives bag type instructions selected by the user, including combinations of FIBC bag types and lifting strap styles, hanging mesh bags, and woven bags; Process style selection module: used to provide a preset process style database and to combine and match it with the combination of container bag type and strap process style in the bag type selection module; Parameter input module: Used to receive component dimension data input by the user and provide an interface for loading default data; Graphics generation module: Connects to the server and, based on the selected bag type, process style, and input component data, calls a preset drawing algorithm to automatically generate a process sheet graphic containing cutting dimensions within 1-3 seconds; Data Management Module: Connects to the local database to store and modify default data for parts, and saves process sheets to the product coding table; Cost accounting module: Includes raw material price list, cutting price list and sewing unit price list, used to automatically calculate production costs based on the generated process sheet; Printing plate management module: Built-in printing data table, which stores and modifies printing process data and images, and adds or deletes printing plate data to the printing data table, and is used to add printing plate patterns to the process sheet; Customer Version Generation Module: This module is used to remove cutting detail fields (such as length, width, and weight) from the process sheet, add a type field, and generate a customer-confirmed version of the process sheet that only contains the finished product dimensions.

[0005] As a preferred technical solution, the system also includes a wire drawing density calculation tool, which is used to automatically calculate wire drawing process data based on input parameters such as fabric width, weight, weaving density, and draw ratio.

[0006] As a preferred technical solution, the local database is used to store default product configuration data, and this default data is not uploaded to the server to ensure the privacy of the enterprise's basic data. Beneficial effects

[0007] Compared with the prior art, the present invention has the following beneficial effects: 1. High efficiency and flexibility: Through arbitrary combinations of bag types and process styles and parametric drawing, process sheets can be automatically generated in seconds, greatly improving the efficiency of process design.

[0008] 2. Data security and management: Default process data and product codes are stored in a local database, which ensures data reusability and avoids the risk of leakage of core process parameters.

[0009] 3. Integrated cost control: The integrated cost accounting module can calculate production costs in real time while generating process sheets, facilitating quick quotation and cost control for enterprises.

[0010] 4. Technical confidentiality: The unique client version generation module can hide the internal cutting process when communicating with clients, only showing the appearance of the finished product, effectively protecting the company's technical secrets. Attached Figure Description

[0029] The present invention will now be described in further detail with reference to the accompanying drawings.

[0030] Reference Figure 1 Upon opening the software client, a login interface will pop up. The system automatically determines the login status; if not logged in, a username and password will be required. The system login validity period is 2 hours. Upon first run of the program, if the product code query button is clicked, and the system detects that no SQLite database instance exists locally, a prompt will automatically appear, and database initialization operations will be performed.

[0031] Reference Figures 2 to 10The core process flow of this invention is as follows: The operator first clicks the bag type selection drop-down list box ( Figure 3 Select the desired bag type and strap design (e.g., square four-span strap); then click the drop-down list box for the design style. Figure 4 Select the corresponding inlet / outlet process.

[0032] Click the component selection button ( Figure 5 In the pop-up window, enter the corresponding component size data. Figure 6 (Unit: mm). Users can also click the "Load Default Data" button. Figure 7 The system retrieves default data from the local database and populates it into the input box. To modify the default value, you can use the "Add / Modify Default Data" button. Figure 8 Enter the configuration window ( Figure 9 Adjustments will be made.

[0033] After confirming the data input is correct, click the "Generate Graphics" button. The system encapsulates the input parameters into a data packet and uploads it to the server. The server performs vector calculations based on the predefined bag-type mathematical model and process combination logic, generates drawing instructions, and returns them to the client. Finally, the client displays a process sheet containing precise cutting annotations. Figure 10 The entire process takes 1-3 seconds.

[0034] After creating the process sheet as described in Example 2, click the Printing Plate Management button, select "Query Printing" from the drop-down list, and in the pop-up window ( Figure 18 Select the row of print patterns you want to add, and click the "Add to Main Form" button on the form. The selected print image will be loaded into the main form. If the required print image does not exist, you can first select "Add Printing Plate" from the drop-down list box to bring up the "Add Printing Image" interface. Figure 17 Enter the printing plate number, or you can use the system's default product code as the plate number. Enter the customer name and product code (or leave it blank). Click the OK button. In the pop-up file selection window, select the printing image you want to add. Select Open to add the image to the printing plate lookup table. Select the added image to scale and drag it. Adjust its size to fit the bag body of the process graphic, and then you can print or save it.

[0035] Reference Figures 11 to 15 The generated process sheet can be saved as a PDF file via the "File - Save" menu, which will bring up a customer information dialog box. Figure 12 After entering customer name and other information, the system first stores the process sheet data in the local product code table for later use via the query window. Figure 13 The process sheet will be retrieved and then saved as a PDF file in the selected folder.

[0036] To prevent the leakage of internal cutting processes, the system has a customer order generation module. Click the "Generate Customer Order" button ( Figure 15 The system automatically filters out cutting fields such as "length", "width", and "weight" and adds a "type" field. At this point, clicking "Generate Graphic" will generate a customer-confirmed process sheet containing only the finished product dimensions.

[0037] Reference Figure 16 The system integrates a tool-based calculation module. Taking the calculation of yarn drawing density as an example, users can select "Yarn Drawing Density Calculation" in the tool menu, input parameters such as fabric width, weight, weaving density, draw ratio, and blade thickness, check the corresponding calculation conditions, and click the calculate button. The system's built-in algorithm engine will automatically calculate the results based on physical formulas and display them to assist in the formulation of production processes.
