Means for Solving the Problems

[0004] According to a first aspect of the present disclosure, a control method for automatic transfer of winding packages applied to a control system for automatic transfer of winding packages is provided. The control system for the automatic transfer of yarn packages includes a Manufacturing Execution System (MES), a first Programmable Logic Controller (PLC), and a plurality of second PLCs, each of which is connected to the first PLC, and each second PLC is connected to at least one work station, and the first PLC is connectable to the MES.

Also, terms such as "including" and "having" and any variations thereof are intended to cover non-exclusive inclusion, for example, covering the inclusion of a series of steps or units.

[0014] Before describing the technical solutions according to the embodiments of the present disclosure, further explanations will be given for the technical terms that can be used in the present disclosure.

[0015] MES: A software system for monitoring and managing the manufacturing process, capable of collecting, processing, and analyzing production data in real time, and optimizing production planning and resource allocation. PLC: An industrial digital computer for controlling automation equipment such as mechanical devices and robots on the production line. It can perform logical operations and processing on input signals according to a preset program and output control signals to control the operation of the equipment. Business data: Data related to operations generated in the manufacturing process, such as equipment status, product quantity, production progress, etc. These data form the basis for decision-making and control by MES and PLC. Transfer instruction information (also referred to as transfer command): It is generated after the MES analyzes based on business data, and is a command and parameter information for instructing equipment to execute transfer tasks.

[0016] Figure 1 shows a schematic diagram of a control system for automatic transfer of winding packages. As shown in Figure 1, the control system for automatic transfer of winding packages includes MES, a first PLC, and a plurality of second PLCs. The plurality of second PLCs are respectively connected to the first PLC, and the first PLC is connected to the MES. Each second PLC is responsible for controlling at least one work station. Here, the second PLC mainly collects and processes real-time business data (i.e., second business data) of the target work station and provides it to the first PLC. The first PLC is responsible for interacting with the second PLC and obtaining the second business data from the second PLC. The first PLC is responsible for interacting with the MES, sending the first business data to the MES, receiving the first transfer instruction information issued by the MES based on the first business data, and notifying the second PLC to execute the first transfer instruction information for the target work station. The first transfer instruction information is transfer permission or transfer prohibition.

[0017] Here, the first business data is collected and processed by the first PLC, and is a data set related to information such as the real-time state of the target work station, the processing progress of the winding package, the detection results of the quality of the winding package, and the required type. These first business data include the states of all related work stations and the operation information to be executed. These data are of great significance in monitoring the operating state of the production line and permitting the decision-making of transfer permission.

[0018] Here, the second operational data is collected and processed by the second PLC and is a data set relating to information such as the real-time status of the target work station, the processing progress of the yarn package, the quality detection results of the yarn package, and the barcode of the yarn package. This data is of great importance in monitoring the operating status of the production line. Each second PLC is configured to acquire and store the second operational data of the target work station it manages. For example, the second PLC stores this data in a data storage area, such as a data block (DB block), that it has assigned to the work station it is responsible for.

[0019] Here, the MES may communicate with the first PLC via a network or other communication method, such as a Management Interface (MI).

[0020] The main types of wound yarn packages relating to the technical proposals of the embodiments of this disclosure may include one or more types such as partially oriented yarns (POY), fully drawn yarns (FDY), and drawn textured yarns (DTY) (or referred to as low-elasticity yarns). For example, the yarn types may specifically include polyester partially oriented yarns, polyester fully drawn yarns, polyester drawn yarns, polyester low-elasticity yarns (Polyester Draw Textured Yarns), and polyester staple fibers (PSF).

[0021] The automated transfer control system for yarn packages according to the embodiment of this disclosure enables the MES to monitor the status of each work station in real time and adjust and optimize as needed through real-time communication and data processing between the MES and the first PLC and the second PLC. This automated control reduces manual intervention, improves the efficiency and accuracy of yarn package transfer, reduces material waste and downtime due to human error, and lowers production costs. This automated control ensures the stability and consistency of yarn packages during the transfer process, contributing to an improvement in overall production rhythm and efficiency. By making the first PLC an intermediate layer between the MES and multiple second PLCs, the automated transfer control system for yarn packages has significant advantages in terms of centralized management, data integration, reduced MES load, improved system scalability, improved safety and stability, and simplified network structure.

[0022] If the MES communicates directly with multiple second PLCs, it will need to process a large amount of real-time data and requests, potentially increasing the load on the MES and impacting its performance. On the other hand, by using the first PLC as an intermediate layer, the MES only needs to communicate with the first PLC, reducing its processing burden. If the first PLC is not used as an intermediate layer, the MES needs to establish direct communication connections with each second PLC, resulting in a complex network configuration that is difficult to manage. By using the first PLC as a relay, the network configuration can be significantly simplified, making the entire communication process clearer and more orderly. The first PLC acts as a safety barrier, verifying and filtering data from the second PLCs to prevent malicious or erroneous data from entering the MES system. Furthermore, the redundancy and fault tolerance mechanisms of the first PLC improve system stability and reliability, ensuring that the production line continues to operate normally even if some equipment fails.

[0023] As production lines expand and are upgraded, it may be necessary to add more second PLCs. If the MES communicates directly with each second PLC, the MES will need to be reconfigured and modified with each expansion. On the other hand, by using the first PLC as an intermediate layer, support for new second PLCs only needs to be added to the first PLC, eliminating the need to change the MES configuration. The first PLC can centrally receive operational data from multiple second PLCs and perform unified processing and analysis. This approach allows for more centralized and orderly control of the entire production line, reducing the complexity and confusion that arises when the MES communicates directly with multiple second PLCs. The first PLC can integrate data from different second PLCs to form a more comprehensive production view, allowing the MES to make decisions based on more comprehensive data and further optimize production planning and resource allocation. The first PLC can also pre-process and filter the data, reducing the amount of data transmitted to the MES and improving communication efficiency.

[0024] Figure 2 is a schematic diagram of the online transfer of an automated transfer control system for a wound yarn package according to an embodiment of the present disclosure. As shown in Figure 2, the first PLC acquires second business data for the target work station from the second PLC, acquires first business data for the target work station based on the second business data, and transmits the first business data to the MES if the control button of the first PLC is in online mode and communication between the first PLC and the MES is normal. The MES determines first transfer instruction information for the target work station based on the first business data and transmits the first transfer instruction information to the first PLC. The first PLC analyzes the first transfer instruction information to obtain the analysis result and returns the analysis result to the second PLC corresponding to the target work station. The second PLC corresponding to the target work station controls the target work station based on the analysis result to execute the transfer task of the wound yarn package.

[0025] In some embodiments, a control button is a physical switch or knob for controlling the operating mode of the first PLC, for switching between the operating modes of the first PLC (e.g., online mode or offline mode). Offline mode is indicated by a specific position or mark on the control button, and when the button is rotated to that position, it indicates that offline mode has been selected to actively interrupt communication with the MES. Online mode is indicated by a specific position or mark on the control button, and when the button is rotated to that position, it indicates that online mode has been selected to maintain communication with the MES.

[0026] In some embodiments, the first PLC specifically converts second business data into first business data in a data storage format according to a preset data storage format, where the first business data is stored in a data storage area assigned to the target work station by the first PLC, and different types of variables in the first business data correspond to different fixed addresses in the data storage area.

[0027] In the online transfer technology according to the embodiment of this disclosure, when the control button of the first PLC is in online mode and communication between the first PLC and the MES is normal, the MES can monitor the status of each work station in real time through real-time communication and data processing between the MES and the first PLC and multiple second PLCs, and can adjust and optimize the transfer strategy as needed to realize automated transfer management of spool packages. By automatically controlling the transfer of spool packages, manual intervention can be reduced, the efficiency and accuracy of spool package transfer can be increased, and production costs can be reduced. By automatically controlling the transfer of spool packages, stability and consistency in the spool package transfer process can be ensured, contributing to an improvement in the overall production rhythm and efficiency.

[0028] In some embodiments, the second PLC corresponding to the target work station is If the analysis result is a transfer permit, the transfer equipment is notified or directly controlled to transport the processed yarn packages from the target work station to the next work station. If the analysis result indicates that transfer is prohibited, this is used to either notify the transfer equipment to prohibit the execution of the transfer task for the spool package at the target work station and to resend the second operational data to the target work station, or to directly control the transfer equipment.

[0029] Here, transfer equipment refers to automated equipment used in a production line to transport materials (e.g., yarn packages) between different work stations, such as conveyors, robotic arms, and automated guided vehicles. The above is merely an illustrative explanation and does not limit all possible equipment included in transfer equipment; it is not exhaustive.

[0030] In this way, the transfer flow of the spooled yarn packages can be precisely controlled by the first PLC and multiple second PLCs, reducing waiting times and manual interventions, improving the overall efficiency of the production line, reducing errors due to human factors, and improving the stability and reliability of the production process. The PLCs can be flexibly programmed, allowing for quick adjustment of the control logic according to production needs and adapting to the processing of different types and specifications of spooled yarn packages. This significantly reduces the dwell time of the spooled yarn packages at the work station, improving the smoothness of the entire production line, and effectively reducing energy consumption and labor costs.

[0031] In some embodiments, the MES specifically, First, analyze the business data to obtain the target string data corresponding to the target work station. This is used to determine whether the spooled yarn package at the target work station meets the transfer conditions based on the target string data. If the transfer conditions are met, the first transfer instruction information is determined to be transfer permission. If the transfer conditions are not met, the first transfer instruction information is determined to be transfer prohibition.

[0032] In some embodiments, the first transfer instruction information is information indicating whether the yarn package in the production line is permitted to be transported to the next work station for further processing. Depending on the determination of the transfer conditions, the first transfer instruction information may be "transfer permitted" or "transfer prohibited."

[0033] In some embodiments, the MES first receives first operational data transmitted from a first PLC. This data typically includes status information of the target work station on the production line, processing progress of the yarn package, quality detection results, and the number of transfer requests. Internally, the MES has a dedicated data analysis module for analyzing the received first operational data and extracting target string data corresponding to the target work station. This target string data may be encoded and represent a specific operating state or attribute. The MES further analyzes the target string data obtained through analysis by comparing it with pre-set transfer conditions. These transfer conditions may include whether the processing quality of the yarn package has reached the target, whether all processing tasks at the current work station have been completed, and whether there is an equipment failure or production abnormality. If the yarn package at the target work station satisfies all the predetermined transfer conditions, the MES determines that the transfer instruction information is "transfer permitted," which indicates that the yarn package can be safely transported to the next work station for processing. If a spool of yarn at a target work station does not meet any of the transfer conditions, the MES may determine that the transfer instruction information is "transfer prohibited" and notify on-site staff to inspect and process by triggering the corresponding alarm mechanism. The MES transmits the determination result (transfer permitted or transfer prohibited) as the first transfer instruction information to a second PLC or other related control equipment via a communication interface. These transfer equipment then execute the corresponding control logic, for example, to start or stop the transport operation of the spool of yarn, based on the received transfer instruction information.

[0034] Taking an automated packaging line in the chemical fiber industry as an example, the first PLC detects that processing of a yarn package at a certain work station (e.g., a work station for measuring weight) is complete, and then transmits first operational data, including status information of the work station, to the MES. After receiving the data, the MES first obtains target string data (e.g., the QR code® of the yarn package for the transfer request, weight information) through analysis, and then compares it with pre-set transfer conditions (e.g., whether the weight of the yarn package of this standard is within the acceptable range; Grade A: within the acceptable range, Grade B: too light, Grade C: too heavy). If the quality level of the yarn package is Grade A, the MES determines that the transfer instruction information is "transfer permitted" and notifies the second PLC to start the transfer operation of the yarn package. If the quality level of the yarn package is Grade B or C, the MES determines that "transfer prohibited" and triggers an alarm mechanism.

[0035] Thus, by analyzing the first operational data and precisely determining the transport conditions using the MES, it is possible to ensure that only spool packages that meet the requirements are transported, thereby improving the accuracy and reliability of production. Furthermore, by timely detection and prevention of the transport of spool packages that do not meet the transport conditions, abnormal situations in the production process, such as equipment failures and quality problems, can be reduced, thereby lowering production risks. By automatically determining and issuing instructions for transport information, manual intervention and waiting times can be reduced, improving the overall operational efficiency of the production line.

[0036] Figure 3 is a schematic diagram of online forced transfer in an automated transfer control system for a wound yarn package according to an embodiment of the present disclosure. As shown in Figure 3, the second PLC is further used to record the forced transfer variable = 1 in the second business data when it is detected that the control button corresponding to the target work station has been switched to manual mode, where the forced transfer variable = 1 indicates that the target work station is requesting forced transfer. The first PLC is further used when the control button of the first PLC is in online mode and communication between the first PLC and the MES is normal, where the forced transfer variable = 1 The first operational data is used to record the forced transfer variable = 1 in the first operational data. The MES is further used to determine second transfer instruction information for the target operational station based on the forced transfer variable if it detects that the forced transfer variable = 1 is included in the first operational data. Here, the second transfer instruction information is a transfer permission. The first PLC, upon receiving the second transfer instruction information, further transmits the analysis results for the second transfer instruction information to the second PLC, which then controls the target operational station based on the analysis results to execute the transfer task of the spool package.

[0037] Here, a control button is a physical switch or knob for manually controlling the state of equipment or a system, and is used to switch the operating mode (e.g., automatic or manual) of the target work station. Manual mode is a specific position or mark on the control button, and when the button is switched to this position, it indicates that manual control mode has been selected to trigger a forced transfer request. In response to the control button corresponding to the target work station being switched to the manual mode position, the forced transfer variable is set to 1, where forced transfer variable = 1 indicates that the target work station is requesting a forced transfer.

[0038] If, for example, an automated production line receives a temporary notification to increase production volume, the investigator switches the control button from automatic to manual mode to ensure the task is completed on time. At this time, the second PLC detects this situation and sends second operational data, including the forced transfer variable = 1, to the first PLC. After processing, the first PLC sends first operational data, including the same forced transfer variable, to the MES. Upon receiving the data, the MES immediately analyzes and checks the value of the forced transfer variable, confirms that the value is 1, and quickly generates "transfer permission" instruction information and sends it to the first PLC. The first PLC then transmits this information to the second PLC, ultimately controlling the target work station to execute the transfer task.

[0039] The online forced transfer technology described in this disclosure enables automated management of online forced transfer of yarn packages and improves the transfer efficiency of yarn packages. By introducing control buttons to the target work stations, operators are allowed to directly intervene in the production flow in specific situations, improving the system's flexibility and ability to handle unexpected events. If it is urgently necessary to skip a work station, the operator can trigger a forced transfer request by quickly rotating the control button, and the system can respond quickly and execute the corresponding control logic. In addition, in the event of equipment failure or maintenance, a portion of the production line can be bypassed by manual control, thereby reducing overall downtime and improving the production efficiency of yarn packages.

[0040] Figure 4 is a schematic diagram of offline transfer in an automated transfer control system for a wound yarn package according to an embodiment of the present disclosure. As shown in Figure 4, the first PLC is used to control the target work station and execute a winding yarn package transfer task when the control button of the first PLC is in offline mode or when communication between the first PLC and the MES is interrupted. The first PLC acquires second business data for the target work station from the second PLC, acquires first business data for the target work station based on the second business data, records the first business data, directly generates third transfer instruction information for the target work station, and transmits the third transfer instruction information to the second PLC. The second PLC is used to control the target work station based on the third transfer instruction information and execute a winding yarn package transfer task, where the third transfer instruction information is a transfer permission.

[0041] In some embodiments, the first PLC continuously monitors the state of a control button directly connected to the first PLC, which is typically mounted on an operation panel and allows the operator to manually switch the operating mode of the first PLC. When the first PLC detects that the control button has been rotated to the "offline mode" position, it immediately records the event and considers that the connection to the MES has been disconnected or is about to be disconnected. It should be noted that such a detection method is immediacy and reliability because it relies primarily on hardware signals (e.g., the switch state of the button). After determining that it is in offline mode, the first PLC retrieves second business data for the target work station from the second PLC according to a predetermined flow and converts it into first business data. Based on the processed first business data, the first PLC controls the transfer task of the spool package by deciding whether or not to send transfer instruction information to the second PLC. Generally, the first PLC sends transfer instruction information of "transfer permitted" to the second PLC. The system is capable of handling various abnormal situations, automatically synchronizing data and restoring connectivity with the MES when conditions are restored.

[0042] Taking an automated packaging line in the chemical fiber industry as an example, a network failure would cause the MES to temporarily lose communication with the first PLC. In this case, the operator can go to the control panel where the first PLC is located and rotate the control button to "offline mode". After detecting this change, the first PLC automatically determines that the connection with the MES has been lost and immediately initiates the transfer control process in offline mode. Subsequently, the first PLC sends a transfer instruction message of "transfer permitted" to the second PLC, ensuring that the yarn package can be smoothly moved from the current work station to the next work station.

[0043] The offline transport technique according to an embodiment of the present invention can achieve automatic management of forced offline transport and automatic recording of offline transport. By introducing a control button to the first PLC, the operator is allowed to directly intervene in the production flow in specific situations, improving the system's flexibility and ability to handle unexpected events. By allowing the operator to manually switch the operating mode of the first PLC, the system can quickly adjust its operating state according to actual needs, improving the system's flexibility and adaptability. State detection of the control button provides an intuitive indication of the connection status between the first PLC and the MES, helping to find and handle connection problems and improving the reliability of the system. If the MES becomes unavailable, the operator can switch the first PLC to offline mode by simply rotating the control button, thereby allowing the system to continue performing transport tasks, simplifying the operation flow and reducing downtime.

[0044] In some embodiments, the first PLC is further used to generate offline data based on first business data when the control buttons of the first PLC are in offline mode or when communication between the first PLC and the MES is interrupted, and to synchronize the offline data with the MES when the control buttons of the first PLC are switched from offline mode to online mode and communication between the first PLC and the MES is restored, wherein the offline data includes transport records to be synchronized with the MES.

[0045] Here, offline data is different from primary operational data; it is not directly obtained through real-time data conversion on the production floor, but rather refers to data that should be recorded during interruptions in communication between the primary PLC and the MES so that it can be subsequently synchronized with the MES. This data may include various production records, events, status changes, etc. If communication between the primary PLC and the MES is interrupted, this data needs to be stored in an offline buffer area to maintain data continuity and integrity. The main use of offline data is to ensure that the data in the MES system is up-to-date and reflects the actual situation on the production floor by synchronizing this data with the MES system after the network is restored or the connection with the MES is re-established. This is important for production management, data analysis, and reporting.

[0046] Assuming that a first PLC and a second PLC are used to automatically control the packaging of spooled yarn, and that the first PLC and the MES system exchange production data in real time, if a network failure occurs one day and communication between the first PLC and the MES is interrupted, important data such as transfer records generated during that time will be stored in the first PLC's offline buffer area. After the network failure is resolved, the first PLC detects that the control button has been switched from offline mode to online mode, and communication with the MES is restored. In this case, the first PLC automatically starts a data synchronization program to synchronize data such as transfer records in the offline buffer area with the MES system, ensuring the integrity and real-time nature of the production data.

[0047] The offline data synchronization technique according to an embodiment of the present invention enables automated synchronization of records for the offline transfer of wound yarn packages, thereby improving the transfer efficiency of wound yarn packages. By recording offline data using the offline buffer mechanism, even if communication between the first PLC and the MES is interrupted, temporary storage of important data and subsequent synchronization can be ensured, improving data synchronization efficiency and reliability. When the control button of the first PLC is switched from offline mode to online mode and communication between the first PLC and the MES is restored, if it is detected that offline data is stored in the offline buffer area, the offline data is synchronized to the MES, ensuring that important data in the production process can be synchronized to the MES system in a timely manner, contributing to real-time understanding and rapid response of the management team regarding the production status. The offline buffer mechanism ensures the integrity and traceability of important data even if communication is interrupted, avoiding the impact on production due to data loss. The automatic synchronization mechanism enables timely detection and resolution of communication failures, improving system stability and reliability.

[0048] In some embodiments, the first PLC assigns multiple offline buffer areas and one offline control area to all target work stations, the multiple offline buffer areas being shared by all target work stations, and the offline control area including associated data digits and associated control digits for synchronizing offline data to the MES.

[0049] Here, the offline buffer area is a specific area partitioned in the first PLC or other storage device, and is used to store data awaiting synchronization in case communication between the first PLC and the MES is interrupted. Here, the offline control area is a dedicated area set up in the second PLC and includes relevant data digits and control digits for controlling the synchronization process of offline data.

[0050] In some embodiments, the first PLC assigns multiple shared offline buffer areas to all target work stations. These areas are used to store offline data generated at each work station during interruptions in communication between the PLC and the MES, such as transfer records and production parameters.

[0051] In some embodiments, if communication between the first PLC and the MES is interrupted, the offline data generated by each target work station is automatically stored in a shared offline buffer area. Simultaneously, the relevant data digits and control digits in the offline control area are updated to reflect the current synchronization status and priority. When communication between the first PLC and the MES is restored, the first PLC checks the status information in the offline control area and determines, based on priority and synchronization strategy, which offline data needs to be synchronized to the MES. The first PLC then sends the offline data from the buffer area to the MES according to a pre-configured format and protocol. After receiving the offline data, the MES performs verification and confirmation. If the data reception and processing are successful, the MES system sends a synchronization confirmation signal to the first PLC. After receiving the confirmation signal, the first PLC updates the status information in the offline control area, clears the synchronized offline data, and frees up buffer space for subsequent use.

[0052] By assigning a shared offline buffer area to all target workstations in this way, it is possible to ensure that important data generated during periods of communication interruption is properly stored, thus avoiding the impact on production due to data loss. The installation of an offline control area allows the PLC to flexibly control the offline data synchronization process, including synchronization priority and the address of the target MES, thereby meeting the needs of different production scenarios. Once communication is restored, the first PLC can quickly synchronize the offline data to the MES, ensuring that management can grasp the production status in real time and respond quickly, thereby improving production efficiency. Synchronization confirmation and leaning mechanisms ensure that synchronized offline data is deleted from the buffer area in a timely manner, avoiding excessive occupation of memory space resources.

[0053] The schematic diagrams shown in Figures 1, 2, 3, and 4 are illustrative, not limiting, and expandable. Those skilled in the art can make various obvious changes and / or substitutions based on the examples in Figures 1, 2, 3, and 4, and the resulting designs should be understood to still fall within the scope of the embodiments of this disclosure.

[0054] Embodiments of the present disclosure provide a method for controlling the automatic transfer of a yarn package, and Figure 5 is a flowchart of the method for controlling the automatic transfer of a yarn package according to an embodiment of the present disclosure. The method for controlling the automatic transfer of a yarn package can be applied to a control device for the automatic transfer of a yarn package, and the control device for the automatic transfer of a yarn package is installed in electronic equipment applied to the control system for the automatic transfer of a yarn package. The electronic equipment includes, but is not limited to, fixed equipment and / or mobile equipment. For example, fixed equipment includes, but is not limited to, a server, and the server may be a cloud server or a general-purpose server. For example, mobile equipment includes, but is not limited to, a mobile phone, a tablet computer, a laptop computer, etc. In some possible embodiments, the method for controlling the automatic transfer of a yarn package may be implemented by a processor calling computer-readable commands stored in memory. As shown in Figure 5, the method for controlling the automatic transfer of a yarn package includes the following steps.

[0055] S501: If the control button of the first PLC is in online mode and communication between the first PLC and the MES is normal, the first PLC acquires the second business data for the target work station from the second PLC.

[0056] S502: The first PLC transmits the first business data of the target work station, acquired based on the second business data, to the MES, which then performs a determination process for online transfer conditions based on the first business data and returns the first transfer instruction information, which is either transfer permitted or transfer prohibited, to the first PLC.

[0057] S503: When the first PLC receives the first transfer instruction information, it transmits the analysis result for the first transfer instruction information to the second PLC, which then controls the target work station based on the analysis result to execute the transfer task of the spool package.

[0058] In some embodiments, the process for determining online transfer conditions is as follows: The system corresponds to a target work station and includes determining whether the spooled yarn package at the target work station meets the transfer conditions based on target string data obtained by analyzing the first business data using MES, determining that the first transfer instruction information is transfer permitted if the transfer conditions are met, and determining that the first transfer instruction information is transfer prohibited if the transfer conditions are not met.

[0059] Thus, when the control button of the first PLC is in online mode and communication between the first PLC and the MES is normal, real-time communication and data processing between the MES, the first PLC, and multiple second PLCs allows the MES to monitor the status of each work station in real time and automatically manage the transfer of the spool packages by adjusting and optimizing the transfer strategy of the work stations as needed. By automatically controlling the transfer of spool packages, manual intervention can be reduced, the efficiency and accuracy of spool package transfer can be increased, and production costs can be reduced. By automatically controlling the transfer of spool packages, stability and consistency of spool packages during the transfer process can be ensured, contributing to an improvement in the overall production rhythm and efficiency.

[0060] In embodiments of the present disclosure, the control method for the automatic transfer of the spool package may further include the second PLC notifying the transfer control equipment to output a transfer abnormality alarm if the analysis result indicates that transfer is prohibited.

[0061] In some embodiments, the transfer abnormality alarm includes, but is not limited to, issuing a warning signal to on-site staff via a device such as an audible or optical alarm or display when it is detected that a winding package does not meet the transfer conditions in an automated transfer control system for winding packages, thereby indicating the abnormal situation that requires action.

[0062] In some embodiments, if the analysis result is "transfer prohibited," the second PLC immediately identifies the presence of an abnormal condition and prepares to trigger the corresponding alarm mechanism. The second PLC sends a command via the communication interface to the transfer equipment to explicitly instruct it to prohibit the execution of the transfer task of the spool package at the current target work station. Furthermore, the second PLC instructs the transfer equipment to activate the transfer abnormality alarm function by sending another signal or command.

[0063] In some embodiments, outputting a transfer anomaly alarm involves immediately activating an alarm device (e.g., an acoustic or optical alarm, a display, etc.) after the transfer equipment receives an alarm command. The alarm device attracts the attention of on-site staff by emitting a clear acoustic or optical signal and displays or broadcasts specific alarm information (e.g., "Transfer of yarn packages is abnormal, please inspect").

[0064] In some embodiments, the second PLC records relevant information about the transfer anomaly event, including the time of occurrence, the affected work station, and the cause of the anomaly, for subsequent analysis and tracking.

[0065] Taking an automated packaging production line in the chemical fiber industry as an example, if a spool of yarn at a certain work station (e.g., the first work station where bags are placed) is determined to be "transfer prohibited" due to a failure in the bagging process, the second PLC immediately notifies the transfer equipment or directly controls the transfer equipment to stop the transport of the spool of yarn and trigger a transfer abnormality alarm. In this case, the audible and optical alarm on the production line emits a loud alarm sound and flashes a red light, and displays information on the screen stating, "There is an abnormality in the transport of the spool of yarn at the first work station where bags are placed; please inspect it." After seeing the alarm, the operator on site immediately goes to the first work station where bags are placed, inspects the problem, and takes appropriate measures to resolve the abnormality. In this way, by outputting a transfer abnormality alarm in a timely manner, the attention of on-site staff can be quickly drawn, the time required to discover and resolve the problem can be shortened, production accidents and quality problems caused by the continued transport of unacceptable spools of yarn can be avoided, and the safety of the entire production line can be improved. By quickly resolving transfer malfunction issues, production line downtime can be reduced, improving production efficiency and capacity.

[0066] Embodiments of the present disclosure provide a method for controlling the automatic transfer of a yarn package, Figure 6 being a flowchart of the method for controlling the automatic transfer of a yarn package according to an embodiment of the present disclosure, the method for controlling the automatic transfer of a yarn package can be applied to a control device for the automatic transfer of a yarn package, the control device for the automatic transfer of a yarn package is installed in electronic equipment applied to the control system for the automatic transfer of a yarn package, the electronic equipment includes, but is not limited to, fixed equipment and / or mobile equipment. For example, fixed equipment includes, but is not limited to, a server, and the server may be a cloud server or a general-purpose server. For example, mobile equipment includes, but is not limited to, a mobile phone, a tablet computer, a laptop computer, etc. In some possible embodiments, the method for controlling the automatic transfer of a yarn package may be implemented by a processor calling computer-readable commands stored in memory. As shown in Figure 6, the method for controlling the automatic transfer of a yarn package includes the following steps.

[0067] S601: When the second PLC detects that the control button corresponding to the target work station has been switched to manual mode, the second PLC records in the second business data that the forced transfer variable = 1, where the forced transfer variable = 1 indicates that the target work station is requesting a forced transfer.

[0068] S602: If the control button of the first PLC is in online mode and communication between the first PLC and the MES is normal, the first PLC records that the forced transfer variable = 1 in the first business data corresponding to the target work station.

[0069] S603: When the MES detects that the forced transfer variable = 1 is included in the first business data, it directly determines the second transfer instruction information, which is a transfer permission for the target work station, based on the forced transfer variable, and does not perform the online transfer condition determination process.

[0070] S604: When the first PLC receives the second transfer instruction information, it sends the analysis results for the second transfer instruction information to the second PLC, which then controls the target work station based on the analysis results to execute the transfer task of the spool package.

[0071] In some embodiments, the process for determining the online transfer conditions is as described above, and will not be explained here.

[0072] In this way, automated management of online forced transfer of spool packages can be achieved, improving the transfer efficiency of spool packages. By introducing control buttons to the target work stations, operators are allowed to directly intervene in the production process in specific situations, improving the system's flexibility and ability to handle unexpected events. If it is urgently necessary to skip a work station, the operator can trigger a forced transfer request by quickly rotating the control button, and the system can respond quickly and execute the corresponding control logic. In addition, in the event of equipment failure or maintenance, a portion of the production line can be bypassed by manual control, reducing overall downtime and improving the production efficiency of spool packages.

[0073] Embodiments of the present disclosure provide a method for controlling the automatic transfer of a yarn package, and Figure 7 is a flowchart of the method for controlling the automatic transfer of a yarn package according to an embodiment of the present disclosure. The method for controlling the automatic transfer of a yarn package can be applied to a control device for the automatic transfer of a yarn package, and the control device for the automatic transfer of a yarn package is installed in electronic equipment applied to the control system for the automatic transfer of a yarn package. The electronic equipment includes, but is not limited to, fixed equipment and / or mobile equipment. For example, fixed equipment includes, but is not limited to, a server, and the server may be a cloud server or a general-purpose server. For example, mobile equipment includes, but is not limited to, a mobile phone, a tablet computer, a laptop computer, etc. In some possible embodiments, the method for controlling the automatic transfer of a yarn package may be implemented by a processor calling computer-readable commands stored in memory. As shown in Figure 7, the method for controlling the automatic transfer of a yarn package includes the following steps.

[0074] S701: If the control button of the first PLC is in offline mode, or if communication between the first PLC and the MES is interrupted, the first PLC obtains the second business data for the target work station from the second PLC and obtains the first business data for the target work station based on the second business data.

[0075] S702: The first PLC records the first business data and directly generates the third transfer instruction information for the target work station. S703: By transmitting a third transfer instruction information, which is an authorized transfer, to the second PLC, the second PLC controls the target work station based on the third transfer instruction information to perform the transfer task of the spool package.

[0076] In this way, it is possible to automatically manage offline forced transfers and automatically buffer the records of offline transfers. By introducing a control button on the first PLC, operators are allowed to directly intervene in the production flow in specific situations, improving the system's flexibility and ability to handle unexpected events. Allowing operators to manually switch the operating mode of the first PLC allows the system to quickly adjust its operating state according to actual needs, improving the system's flexibility and adaptability. Control button state detection provides intuitive indication of the connection status between the first PLC and the MES, contributing to the detection and handling of connection problems and improving system reliability. If the MES becomes unavailable, the operator can easily switch the first PLC to offline mode by rotating the control button, allowing the system to continue performing transfer tasks. Even in offline mode, the first PLC can still generate transfer instruction information for the target workstation, simplifying the operation flow and reducing downtime. The offline buffer mechanism ensures data integrity and reduces production interruptions due to data synchronization problems.

[0077] In some embodiments, the control method for the automatic transfer of the yarn package is as follows: If the control button of the first PLC is in offline mode, or if communication between the first PLC and the MES is interrupted, the first PLC generates offline data, including transport records to be synchronized with the MES, based on the first business data. The method may further include synchronizing offline data with the MES when the control button of the first PLC is switched from offline mode to online mode and communication between the first PLC and the MES is restored.

[0078] Here, the first operational data is converted by the first PLC from the second operational data obtained from the second PLC corresponding to the target work station. This second operational data typically includes information such as the real-time production status, parameters, and results of the target work station. If the connection between the first PLC and the MES is disconnected, the first PLC records this first operational data converted by the second PLC. The first operational data is primarily used to support production control of the target work station, for example, the control of the winding package transfer task. This first operational data can reflect the operating status of the target work station in real time or near real time.

[0079] Here, offline data is different from the first operational data; it is not directly obtained through real-time data conversion on the production floor, but rather refers to data that should be recorded during interruptions in communication between the first PLC and the MES so that it can be subsequently synchronized with the MES. This data may include various production records, events, status changes, etc.

[0080] In this way, automated synchronized management of offline transfer records of yarn packages can be achieved, improving the transfer efficiency of yarn packages. By recording offline data using the offline buffer mechanism, even if communication between the first PLC and the MES is interrupted, temporary storage of important data and subsequent synchronization can be ensured, improving the efficiency and reliability of data synchronization. When the control button of the first PLC is switched from offline mode to online mode and communication between the first PLC and the MES is restored, if it is detected that offline data is stored in the offline buffer area, the offline data is synchronized with the MES, ensuring that important data in the production process can be synchronized with the MES system in a timely manner, contributing to real-time understanding and rapid response of management regarding the production status. The offline buffer mechanism ensures the integrity and traceability of important data even if communication is interrupted, avoiding the impact on production due to data loss.
