[0030] The embodiments of this application are written in a progressive manner.

[0031] As Figure 1 shown, the embodiments of this application provide a control system for a tipping and linking unit, including: a human-machine interaction unit 1, a PLC control unit 2, a servo control unit 3, a safety control component 4, and a servo component 5, where: The human-machine interaction unit 1 is used to issue logic control tasks to the PLC control unit 2, where the logic control tasks include safety logic control tasks and non-safety logic control tasks; Specifically, the human-machine interaction unit 1, as the upper computer of the entire control system, mainly undertakes tasks such as parameter storage, issuance of parameters and instructions, status monitoring, and diagnosis; the human-machine interaction unit 1 can communicate with the PLC control unit 2 through the Ethernet communication protocol and the ADS (Automation Device Specification) communication protocol, where the ADS communication protocol is a protocol developed by Beckhoff for communication between automation devices and is widely used in the TwinCAT system. This application does not make specific limitations on this.

[0032] Among them, the logic control tasks include safety logic control tasks and non-safety logic control tasks. The safety logic control tasks specifically refer to the logic control tasks related to safety control in the cigarette making and tipping unit. The core of the safety logic control tasks is the safety logic, which is a special control logic dedicated to processing safety-related input signals, such as safety torque off (STO), safety stop (SS1), safety speed limit (SLS), etc., and outputting corresponding safety control instructions according to the status of these signals. Its purpose is to immediately place the cigarette making and tipping unit in a safe state when detecting potential dangers, preventing the occurrence or expansion of accidents. The non-safety logic control tasks, also known as conventional logic control tasks, refer to the conventional control logic tasks used to implement the production process in the cigarette making and tipping unit. These tasks generally do not involve direct safety functions, but are used to optimize the production process, improve production efficiency, ensure product quality, and ensure the normal operation of the equipment. The core is to process input signals (such as operator instructions, etc.) through a logic controller and output corresponding control instructions (such as motor start and stop, etc.) according to preset logic rules. Different from the safety logic control tasks, the non-safety logic control tasks mainly focus on production efficiency, product quality, and the normal operation of the equipment, rather than directly involving personnel safety or the prevention of major equipment failures.

[0033] The PLC control unit 2 is used to issue a first control signal to the servo control unit 3 through the Profisafe safety bus according to the safety logic control task, and issue a first control instruction to the safety control component 4 through the FSoE safety bus, so that the safety control component 4 executes the first control instruction; the servo control unit 3 is used to issue a second control instruction to the servo component 5 through the Profisafe safety bus according to the first control signal, so that the servo component 5 executes the second control instruction; Specifically, the PLC control unit 2 can be implemented by an existing PLC controller. The PLC control unit 2 can include several PLC controllers, and this application does not make specific limitations on this; the PLC control unit 2 can be communicatively connected to the safety control component 4 through the FSoE (Fail-Safe over EtherCAT) safety bus; among them, FSoE is a functional safety protocol based on the EtherCAT network, used to implement safety-related communications in an industrial automation environment. It allows the parallel transmission of standard data and safety data in the same network, ensuring that safety measures can be taken quickly and reliably in case of a failure. The safety control component 4 generally consists of a safety input module, a safety output module, safety detection devices, safety execution devices, etc., and this application does not make specific limitations on this. When performing the safety logic control task, the PLC control unit 2 generates a processed first control instruction according to the safety logic control task and issues it to the safety control component 4, so that the safety control component 4 executes the first control instruction.

[0034] Specifically, the PLC control unit 2 can be communicatively connected to the servo control unit 3 via the Profisafe safety bus. Among them, Profisafe is a functional safety communication profile proposed by Profibus International (PI), which is loaded on top of the Profibus DP and Profinet IO communication protocols. It ensures the reliable transmission of safety-related data by adding a safety transmission protocol to the standard communication protocol, thus meeting the requirements for functional safety in industrial automation. When performing safety logic control tasks, the PLC control unit 2 generates a processed first control signal, such as Safe Torque Off (STO), Safe Stop 1 (SS1), Safe Limited Speed (SLS), etc., according to the safety logic control tasks, and sends it to the servo control unit 3 via the Profisafe safety bus.

[0035] Specifically, the servo control unit 3 can be implemented using existing servo controllers. The servo control unit 3 can include several servo controllers, and this application does not make specific restrictions on this. The servo control unit 3 can be communicatively connected to the servo components 5 via the Profisafe safety bus. The servo components 5 are generally composed of detection devices and execution devices (such as servo motors), and this application does not make specific restrictions on this. When performing safety logic control tasks, the servo control unit 3 generates a processed second control instruction according to the first control signal and sends it to the servo components 5 to make the servo components 5 execute the second control instruction.

[0036] The PLC control unit 2 is also used to send a second control signal to the servo control unit 3 via the Profinet bus and a third control instruction to the safety control component 4 via the EtherCAT bus according to non-safety logic control tasks, so that the safety control component 4 executes the third control instruction. The servo control unit 3 is also used to send a fourth control instruction to the servo components 5 via the Profinet bus according to the second control signal, so that the servo components 5 execute the fourth control instruction.

[0037] Specifically, the PLC control unit 2 can also be communicatively connected to the safety control component 4 via the EtherCAT bus. Among them, EtherCAT is a high-performance Ethernet fieldbus system designed specifically for industrial automation and control applications. It achieves extremely high communication speeds and low latency by optimizing the Ethernet protocol, and can meet the requirements of real-time control. When performing non-safety logic control tasks, the PLC control unit 2 generates a processed third control instruction according to the non-safety logic control tasks and sends it to the safety control component 4 to make the safety control component 4 execute the third control instruction.

[0038] Specifically, the PLC control unit 2 can also be communicatively connected to the servo control unit 3 via the Profinet bus. Among them, Profinet is a communication protocol based on industrial Ethernet. It is the Ethernet version of Profibus and is developed by the Profibus International Organization. When performing non-safe logic control tasks, the PLC control unit 2 generates a processed second control signal according to the non-safe logic control tasks and sends it to the servo control unit 3.

[0039] Specifically, the servo control unit 3 can also be communicatively connected to the servo component 5 via the Profinet bus. When performing non-safe logic control tasks, the servo control unit 3 generates a processed fourth control instruction according to the second control signal and sends it to the servo component 5, so that the servo component 5 executes the fourth control instruction.

[0040] In traditional cigarette making and tipping machines, the connection method of safety outputs adopts a hardwired form. Since there are a large number of servo motors in the cigarette making and tipping machines, the number of hardwired connections is huge, resulting in a significant increase in the frequency of faults and making it difficult to ensure the long-term stable operation of the equipment. The above embodiments relate to a control system of a cigarette making and tipping machine, including: a human-machine interaction unit 1, a PLC control unit 2, a servo control unit 3, a safety control component 4, and a servo component 5. Among them, the PLC control unit 2 can send a first control signal to the servo control unit 3 via the Profisafe safety bus and send a first control instruction to the safety control component 4 via the FSoE safety bus according to the safe logic control tasks; the PLC control unit 2 can also send a second control signal to the servo control unit 3 via the Profinet bus and send a third control instruction to the safety control component 4 via the EtherCAT bus according to the non-safe logic control tasks. By supporting two types of safety bus protocols, FSoE and Profisafe, the transmission of servo safety control data is changed from a hardwired form to a safety bus transmission form. Compared with traditional cigarette making and tipping equipment using relays and hardwired forms, the above embodiments greatly simplify the wiring method, reduce the probability of faults, and make the transmission of safety data more flexible and stable. In summary, the above embodiments can effectively improve the operation stability of the cigarette making and tipping machine.

[0041] In other embodiments of the present application, the PLC control unit 2 includes a safety PLC control module and a conventional PLC control module, where: The safety PLC control module is used to send a first control signal to the servo control unit 3 via the Profisafe safety bus and send a first control instruction to the safety control component 4 via the FSoE safety bus according to the safe logic control tasks, so that the safety control component 4 executes the first control instruction; A conventional PLC control module is used to issue a second control signal to the servo control unit 3 via the Profinet bus and a third control instruction to the safety control component 4 via the EtherCAT bus according to non-safety logic control tasks, so that the safety control component 4 executes the third control instruction.

[0042] Specifically, the safety PLC control module can be implemented using an existing safety PLC controller, and the conventional PLC control module can be implemented using an existing conventional PLC controller. The number of safety PLC controllers and conventional PLC controllers can be several, and this application does not make specific restrictions on this. Among them, the safety PLC control module is used to execute safety logic control tasks, and it is communicatively connected to the servo control unit 3 and the safety control component 4 via the Profisafe safety bus and the FSoE safety bus respectively. The conventional PLC control module is used to execute non-safety logic control tasks, and it is communicatively connected to the servo control unit 3 and the safety control component 4 via the Profinet bus and the EtherCAT bus respectively.

[0043] In this embodiment, by dividing the PLC control unit 2 into a safety PLC control module and a conventional PLC control module, it can ensure the independent operation of the safety function, reduce the interference of conventional tasks on the safety function, and improve the operation stability of the cigarette making and tipping unit.

[0044] In other embodiments of this application, in the control system of the above cigarette making and tipping unit, an IPC control unit is further included, where: the human-machine interaction unit 1 is connected to the PLC control unit 2 via the IPC control unit; the PLC control unit 2 is also connected to the servo control unit 3 via the IPC control unit.

[0045] The human-machine interaction unit 1 includes an industrial computer and an interaction device connected to each other, where: the interaction device is used to obtain task parameters input by the user; the industrial computer is also connected to the PLC control unit 2 via the IPC control unit; the industrial computer is used to generate logic control tasks according to the task parameters and issue the logic control tasks to the PLC control unit 2 via the IPC control unit. The human-machine interaction unit 1 further includes a switch, and the industrial computer is connected to the IPC control unit via the switch.

[0046] Specifically, the networking form of the control system of the above cigarette making and tipping unit is as Figure 2As shown in the figure. Among them, the IPC control unit can adopt an existing embedded IPC controller, which has rich computer communication interfaces and a large amount of storage functions, strong scalability, supports multiple bus interfaces, and is convenient for network extension. This application does not make specific restrictions on this. The X0 network card port of the embedded IPC controller, the industrial computer in the human-machine interaction unit 1, and the switch form an Ethernet network, and the X1 network card port and multiple servo controllers in the servo control unit 3 form a Profinet network. The safety PLC controller, the safety input module and safety output module in the safety control component 4, etc., and the general input module and general output module in the PLC control unit 2 (such as: digital input module, digital output module, analog input module, analog output module), etc., form an EtherCAT network through backplane wiring. Safety data communication is realized through the corresponding safety bus protocols FSoE and Profisafe.

[0047] The industrial computer (Industrial Personal Computer, IPC), as the controller of the human-machine interaction unit 1, undertakes the task of issuing option parameters and configuration instructions. After the user inputs task parameters through an external device such as a touch screen, the industrial computer can generate a logical control task according to the corresponding task parameters and send it to the PLC control unit 2 through the switch and the IPC control unit.

[0048] In this embodiment, introducing an advanced IPC into the control system of the cigarette making and tipping machine group, combined with a dedicated software development platform, can make the control system design of the cigarette making and tipping machine group highly modular, greatly reducing the complexity and cost of system integration and maintenance. In addition, the modular configuration function is also conducive to promoting the management of the control system from a manual configuration method to an automatic configuration method, and can provide an efficient, economical and reliable solution for the intelligent and automatic control of the cigarette making machine group.

[0049] Currently, when the user selects different personalized options, the safety configuration of the cigarette making and tipping machine group may change, and the developer needs to select different safety configuration program versions according to the user's needs and download them to the controller. The more user requirement categories there are, the more program versions the developer needs to manage. In addition, the user's needs may be constantly changing, and the functions need to be switched frequently, and the program versions also need to be manually synchronized and adjusted, resulting in a sharp increase in the developer's management workload.

[0050] Accordingly, as Figure 3 shown, in another embodiment of this application, a configuration method for the control system of a cigarette making and tipping machine group is further provided, which is applied to the control system of the cigarette making and tipping machine group as described above. The control system of the cigarette making and tipping machine group includes: a human-machine interaction unit 1, a PLC control unit 2, a servo control unit 3, a safety control component 4, and a servo component 5. The method includes: S101. Use the human-machine interaction unit 1 to obtain the configuration parameters input by the user, and perform configuration operations according to the configuration parameters. Specifically, the configuration parameters set by the user based on personalized needs can be obtained through the interaction device in the human-machine interaction unit 1, via a graphical interface or a configuration tool, so as to perform corresponding configuration operations according to the configuration parameters. For example, the acquisition frequency of the sensor, the logical relationship of the control device, and the display content of the human-machine interface can be set through configuration software. This configuration method avoids complex programming and enables the control system to quickly adapt to different control requirements.

[0051] In some embodiments, the control system of the cigarette making and tipping machine group further includes an IPC control unit. The human-machine interaction unit 1 is connected to the PLC control unit 2 through the IPC control unit, and the PLC control unit 2 is also connected to the servo control unit 3 through the IPC control unit. One implementation method of this step specifically includes: Use the human-machine interaction unit 1 to obtain the configuration parameters input by the user, call the API interface of the Visual Studio development platform in the human-machine interaction unit 1, open the TwinCAT3 project of the TwinCAT3 control software in the IPC control unit, and switch the hardware configuration according to the configuration parameters, activate the latest configuration of the TwinCAT3 project and restart the TwinCAT3 project.

[0052] Specifically, the user sets parameters through the human-machine interaction unit 1. After the configuration parameters are confirmed, the API (Application Programming Interface) of the Visual Studio development platform is called to open the TwinCAT3 project of the IPC controller in the IPC control unit, switch the hardware configuration according to the specific parameter configuration content of the configuration parameters, and activate the latest configuration of the TwinCAT3 project and restart the TwinCAT3 project. In addition, the process of abnormal execution of the configuration switch can be recorded by printing an error list. For the specific process of configuration, reference can be made to Figure 4 as shown. Among them, the project file of the human-machine interaction unit 1 is created through the development platform Visual Studio, and the programming language is designed using C#. The PLC program is created, debugged, and deployed through the development platform TwinCAT3, and the general PLC program is designed in the ST (Structured Text) structured text language.

[0053] S102. Use the human-machine interaction unit 1 to obtain the security configuration parameters input by the user, and send the security configuration parameters to the PLC control unit 2. S103. Use the PLC control unit 2 to perform security configuration operations according to the security configuration parameters. Specifically, after the configuration operation is completed, the safety configuration parameters set by the user based on personalized requirements can be obtained through the interaction device in the human-machine interaction unit 1, and the safety configuration parameters can be sent to the PLC control unit 2 through a dedicated software tool, so that the PLC control unit 2 can perform relevant safety configuration operations according to the safety configuration parameters.

[0054] In some embodiments, one implementation manner of step S102 specifically includes: using the human-machine interaction unit 1 to obtain the safety configuration parameters input by the user, sending the safety configuration parameters to the IPC control unit through the TwinSAFE Loader software tool, and sending the safety configuration parameters to the PLC control unit 2 through the controller in the IPC control unit.

[0055] Specifically, TwinSAFE Loader is an independent command-line tool software developed by Beckhoff Automation GmbH, which is used to download, customize and manage TwinSAFE safety projects without relying on the TwinCAT3 development environment. The specific process of safety configuration can be referred to Figure 5 As shown. After the configuration operation is completed, wait for the IPC controller in the IPC control unit to enter the running mode. The human-machine interaction unit 1 starts the task of switching the safety configuration, and downloads the automatically generated safety configuration file according to the safety configuration parameters to the safety PLC controller in the PLC control unit 2 through the software tool TwinSAFELoader to complete the safety configuration operation. The safety program can be created, debugged and deployed through the development platform TwinCAT3. The conventional PLC program and the safety PLC program can be designed by ST structured text language and FBD (Function Block Diagram) function block diagram language respectively.
