Description

Technical Field

[0001] The present invention belongs to the technical field of chemical fiber production, and in particular relates to a chemical fiber production process tracing method and chemical fiber production equipment. Background Art

[0002] Currently, the chemical fiber industry has increasingly stringent requirements for product quality and production efficiency, making traceability of product quality issues increasingly important. Through product quality traceability, the entire production cycle of a specific product can be obtained, along with production data information at any point in the process.

[0003] Currently commonly used product quality traceability methods mainly include:

[0004] The process of attaching text labels to products and tracing products based on the content of the labels is complex and tedious, and cannot be digitized or stored in an informational manner. Once the text labels are blurred or lost, product quality traceability will be impossible.

[0005] At the same time, this method can only trace products from a single process, not products that cross multiple processes. The traceability effect is poor and the traceable content is very limited. Furthermore, text labels need to be manually affixed according to the corresponding relationship, which is prone to errors.

[0006] In view of this, the present invention is proposed. Summary of the Invention

[0007] The technical problem to be solved by the present invention is that the existing product tracing methods are unable to trace cross-process products, the tracing effect is poor, and the traceable content is very limited. A tracing method for a chemical fiber production process and chemical fiber production equipment are provided, which can realize cross-process tracing of products, have high tracing efficiency, and the traced production information is comprehensive, accurate, and reliable.

[0008] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is: a tracing method for a chemical fiber production process, the chemical fiber production process includes several workstations, and the several workstations, raw materials, and products are coded respectively;

[0009] During the production process, the raw material codes are obtained and entered into the production management system. When the raw materials pass through different workstations, the codes of the corresponding workstations, the production information of the raw materials at the workstations, and the codes of the prepared products are obtained, and then entered into the production management system in correspondence with the raw material codes.

[0010] When the production management system obtains the product code, it can reversely trace the work station information, production information and raw materials associated with the product.

[0011] Furthermore, the production information includes equipment information, production time and quality inspection information on the corresponding workstation;

[0012] Preferably, the device information includes: device location information, device operating parameters, and device operating time.

[0013] Furthermore, the chemical fiber production process includes polymerization process, drying process, spinning process and false twist texturing process.

[0014] When the polymerization process, drying process, spinning process and false twist texturing process are carried out continuously, the coding of the raw materials of the polymerization process is obtained and entered into the production management system;

[0015] When the polymerization process raw materials pass through each station of the polymerization process, drying process, spinning process and false twist texturing process, the code of the corresponding station, the production information at the corresponding station and the code of the prepared product are obtained, and entered into the production management system and associated with the code of the polymerization process raw materials.

[0016] Furthermore, when the raw materials in the false twist texturing process include products prepared in the spinning process and other added raw materials, the other added raw materials are coded and entered into the production management system, correspondingly associated with the codes of the raw materials in the polymerization process.

[0017] Furthermore, when the production management system obtains the product code, the information of each workstation of the polymerization process, drying process, spinning process and false twisting process associated with the product code, production information and corresponding polymerization process raw materials or other added raw materials can be retrieved from the production management system.

[0018] Furthermore, the chemical fiber production process includes a polymerization process, a drying process, a spinning process and a false twist texturing process. When the polymerization process, the drying process, the spinning process and the false twist texturing process are carried out discontinuously, the codes corresponding to the raw materials in the polymerization process, the drying process, the spinning process and the false twist texturing process are obtained respectively and entered into the production management system.

[0019] Furthermore, during the false twist texturing process:

[0020] Encode the raw materials for false twist texturing process;

[0021] Obtain the code of the raw materials and enter it into the production management system;

[0022] When raw materials pass through different workstations, the code of the corresponding workstation, the production information of the raw materials at the workstation, the code of the prepared product, and the production time / production sequence corresponding to the different coded products are obtained, and entered into the production management system and associated with the code of the raw materials;

[0023] Preferably, the raw material of the false twist texturing process is raw silk, and the false twist texturing process processes the raw silk into stretched textured yarn.

[0024] Obtain the raw silk code and enter it into the production management system;

[0025] When the raw silk is on the raw silk rack, the raw silk rack code and the time when the raw silk was put on the rack are obtained, and the raw silk rack code and the raw silk code are recorded in the production management system;

[0026] When the bobbins for winding the draw-textured yarn are installed on the false twist texturing equipment, the bobbin codes and the order / time of bobbins loading are obtained and entered into the production management system;

[0027] After the winding of the yarn bobbin is completed, when the production management system obtains the yarn bobbin code, it can reversely trace the yarn bobbin's machine loading sequence / machine loading time, work station information, production time, and raw materials.

[0028] Furthermore, the production management system pre-stores workstation information, production information, and product information corresponding to raw materials with different codes according to the production plan;

[0029] When the production management system obtains the raw material code, it can trace the workstation information, production information and product information corresponding to the raw material forward;

[0030] Preferably, the product information includes product quality, product physical properties, and product chemical properties.

[0031] Furthermore, the production management system obtains the raw material / product coding in the following ways:

[0032] The raw material / product code is a QR code, bar code or RFID code, which is obtained by scanning the QR code, bar code or RFID code with a scanning device that is communicatively connected / electrically connected to the production management system;

[0033] Alternatively, the code of the raw material / product is a serial number, and the code of the raw material / product is obtained by entering the serial number into an input system of the production management system.

[0034] The present invention also provides a chemical fiber production equipment, and the raw materials used in the chemical fiber production equipment and the products prepared therefrom can be traced by any of the traceability methods described in the above schemes.

[0035] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0052] like Figures 1 to 4As shown, the present invention discloses a chemical fiber production process tracing method and chemical fiber production equipment.

[0053] Specifically, if Figure 1 As shown, the chemical fiber production process includes several workstations, and the workstations, raw materials, and products are coded separately;

[0054] During the production process, the raw material codes are obtained and entered into the production management system. As the raw materials pass through different workstations, the codes of the corresponding workstations, the production information of the raw materials at the workstations, and the codes of the prepared products are obtained, and entered into the production management system in correspondence with the raw material codes.

[0055] When the production management system obtains the product code, it can reversely trace the work station information, production information and raw materials associated with the product.

[0056] The present invention associates the codes of workstations, products, production information on the workstations with the codes of raw materials, thereby not only realizing cross-process traceability of products, but also achieving high traceability efficiency and making the traced production information comprehensive, accurate and reliable.

[0057] Production information in this context includes equipment information, production time, and quality inspection information for the corresponding workstation. Specifically, equipment information includes equipment location information, equipment operating parameters, and equipment operating time. Production time includes the time when raw materials enter and leave the workstation. Quality inspection information includes quality inspection reports for products at each workstation.

[0058] The chemical fiber production process includes polymerization, drying, spinning, and false twist texturing. The product produced in the polymerization process is dried and used as raw material in the spinning process to produce preformed yarn. The preformed yarn is then used as raw material in the false twist texturing process, where it is processed into stretched textured yarn.

[0059] As an embodiment of the present invention, Figure 2 As shown, when the polymerization process, drying process, spinning process and false twist texturing process are continuously carried out, the code of the raw materials of the polymerization process is obtained and entered into the production management system;

[0060] When the polymerization process raw materials pass through each station of the polymerization process, drying process, spinning process and false twist texturing process, the code of the corresponding station, the production information at the corresponding station and the code of the prepared product are obtained, and entered into the production management system and associated with the code of the polymerization process raw materials.

[0061] Specifically, obtain the coding of the raw materials for the polymerization process and enter it into the production management system;

[0062] When polymerization begins, when the polymerization process raw materials pass through different stations of the polymerization process, the code of the corresponding station, the production information of the polymerization process raw materials at the station and the code of the prepared polymerization process product are obtained and entered into the production management system;

[0063] After the polymerization is completed and drying begins, when the polymerization process product passes through different stations of the drying process, the code of the corresponding station, the production information of the polymerization process product at the station and the code of the prepared drying process product are obtained and entered into the production management system;

[0064] After drying is completed, spinning begins. When the drying process product passes through different stations of the spinning process, the code of the corresponding station, the production information of the drying process product at the station, and the code of the prepared spinning process product are obtained and entered into the production management system;

[0065] After spinning is completed, false twisting and texturing begins. When the spun product passes through different stations of the false twisting and texturing process, the code of the corresponding station, the production information of the spun product at the station, and the code of the prepared false twisting and texturing product are obtained and entered into the production management system;

[0066] The coding of the workstations of the polymerization process, drying process, spinning process and false twist texturing process in the production management system, the production information on the workstations, the coding of the prepared products and the corresponding coding of the polymerization process raw materials are associated.

[0067] When the production management system obtains the product code, it can control the production management system to output the work station information, production information and raw material related information associated with the product with the corresponding code.

[0068] Among them, the production management system can obtain the codes of polymerization process products, drying process products, spinning process products, and false twist texturing process products, and control the production management system to output the work station information, production information and raw material related information associated with the corresponding product codes according to the obtained codes.

[0069] In this embodiment, the code of a false-twist texturing product, spinning product, drying product, or polymerization product can be used to obtain information about any associated workstation, production information, and raw materials within the entire production process, including polymerization, drying, spinning, and false-twist texturing. This enables cross-process product traceability, resulting in effective and more accurate traceability, and conveniently allowing users to obtain information about the production status of each process in a product's production process.

[0070] As an embodiment of the present invention, Figure 3As shown, when the raw materials in the false twist texturing process include products prepared in the spinning process and other added raw materials, the other added raw materials are coded and entered into the production management system, and are correspondingly associated with the codes of the raw materials in the polymerization process.

[0071] Specifically, when the false twist texturing process begins, other added raw materials are first coded and entered into the production management system, and there is no need to re-code the products prepared in the spinning process.

[0072] When the spinning process products and other added raw materials pass through different stations of the false twist texturing process, the code of the corresponding station, the production information of the spinning process products at the station and the code of the prepared false twist texturing process products are obtained and entered into the production management system.

[0073] The codes of the workstations in the production management system, the production information at the workstations, and the codes of the prepared products are associated with the corresponding codes of the polymerization process raw materials and the codes of other added raw materials.

[0074] When the production management system obtains the product code, it can control the production management system to output the work station information, production information and raw material related information associated with the product with the corresponding code.

[0075] Furthermore, when the production management system obtains the product code, the information of each workstation of the polymerization process, drying process, spinning process and false twisting process associated with the product code, production information and corresponding polymerization process raw materials or other added raw materials can be retrieved from the production management system.

[0076] In this embodiment, other added raw materials in the false twist texturing process are also associated to ensure that users can accurately obtain all raw material information corresponding to the false twist texturing process products, avoid omissions, and ensure the accuracy and comprehensiveness of traceability information.

[0077] In another embodiment of the present invention, a chemical fiber production process includes a polymerization process, a drying process, a spinning process, and a false twist texturing process. When the polymerization process, the drying process, the spinning process, and the false twist texturing process are performed discontinuously, codes corresponding to raw materials in the polymerization process, the drying process, the spinning process, and the false twist texturing process are obtained and entered into a production management system.

[0078] As an implementation method of this embodiment, the polymerization process specifically includes: a polymerization preparation stage and a polymerization production process association stage;

[0079] During the polymerization preparation phase, the raw materials required for the polymerization process must be coded. This coding can be performed by the supplier, and the coded information is transmitted to the production user. The code includes: raw material name, implementation standard, raw material grade, net weight, batch number, production date, manufacturer, and remarks.

[0080] In the association stage of the polymerization production process, after the raw materials enter the factory, the raw material code is first entered into the production management system; then the raw material code is associated with the production plan in the production management system, and the material is added.

[0081] During the polymerization production process, when the raw materials pass through different workstations, the codes of the corresponding workstations, the production information of the raw materials at the workstations, and the codes of the prepared products are obtained, and entered into the production management system in correspondence with the codes of the raw materials;

[0082] After the polymerization production process is completed, the product is taken offline and the product code, product offline time and product offline order are recorded.

[0083] In this embodiment, by obtaining the product code, the location information of the equipment in the aggregate production process, the equipment operating parameters, the equipment operating time, the product offline time and the product offline order and other information can be traced back to ensure the accuracy and comprehensiveness of the aggregate product traceability information.

[0084] As another implementation of this embodiment, the spinning process specifically includes: a spinning preparation stage and a spinning production process associated stage;

[0085] During the spinning preparation stage, the raw materials required for the spinning process need to be coded. This coding can be done by the supplier, who then transmits the information to the production user, or by the upstream process. The coding includes: raw material name, implementation standard, brand, batch number, package number, raw material grade, net raw material content, production date, manufacturer, and notes.

[0086] In the associated stage of the spinning production process, if the spinning is carried out directly after the polymerization is completed, when the production management system obtains the code of the product of the spinning process, it can reversely trace the polymerization process and spinning process station information, production information and polymerization process raw materials corresponding to the product.

[0088] In case of composite spinning, multiple chip materials and additives are used as raw materials and coded separately.

[0089] In this embodiment, by obtaining the coding of the spinning process products, the location information of the equipment in the spinning production process, the operating parameters of the equipment, the operating time of the equipment, the order of product offline, and other information can be traced back, making the information obtained by tracing the spinning process products more accurate and comprehensive.

[0090] In addition, the chip raw materials and additives in chip spinning and composite spinning are coded separately and entered into the production management system, which further ensures the accuracy of the raw material information for the traceability of spinning process products and makes it easier for users to obtain information on all raw materials corresponding to the product based on the product code.

[0091] As another implementation method of this embodiment, during the false twist texturing process:

[0092] Encode the raw materials for false twist texturing process;

[0093] Obtain the code of the raw materials and enter it into the production management system;

[0096] Obtain the raw silk code and enter it into the production management system;

[0097] When the raw silk is on the raw silk rack, the raw silk rack code and the time when the raw silk was put on the rack are obtained, and the raw silk rack code and the raw silk code are recorded in the production management system;

[0098] When the bobbins for winding the draw-textured yarn are installed on the false twist texturing equipment, the bobbin codes and the order / time of bobbins loading are obtained and entered into the production management system;

[0099] After the winding of the yarn bobbin is completed, when the production management system obtains the yarn bobbin code, it can reversely trace the yarn bobbin's machine loading sequence / machine loading time, work station information, production time, and raw materials.

[0100] In this embodiment, the coding of the wire reels can be used to trace the order / time of loading the wire reels onto the machine, the work station information, the production time, and the raw materials, so that the user can more accurately know the production process of the stretched and deformed wire on the wire reels, and strictly and specifically trace the specific production time and process of the stretched and deformed wire, making the traced information more accurate.

[0104] This embodiment obtains the work station information, production information and product information corresponding to the raw materials through forward traceability of raw materials, which makes it convenient for users to track the entire production process of raw materials, determine the information of products produced from raw materials, as well as the production equipment used in the production process of raw materials, the time consumed in production, etc.

[0105] As another embodiment of the present invention, the production management system obtains the coding of the raw materials or products in a manner including scanning or manual entry.

[0106] Specifically, the raw material / product code is a QR code, barcode, or RFID code, which is obtained by scanning the QR code, barcode, or RFID code using a scanning device that is communicatively connected or electrically connected to the production management system. In other words, by scanning the QR code, barcode, or RFID code of a raw material or product, relevant production plans, workstation information, production information, raw material information, and so on can be retrieved.

[0107] Alternatively, the raw material / product code is a serial number, which is entered into the production management system's data entry system to obtain the raw material / product code. In other words, by entering the raw material or product serial number, relevant production plans, workstation information, production information, raw material information, etc. can be queried.

[0108] The present invention also provides a chemical fiber production device, and the raw materials used in the chemical fiber production device and the products prepared therefrom can be traced by the traceability method described in any one of the above embodiments.
