Description
Technical Field
[0001] This invention belongs to the technical field of cigarette production equipment, specifically relating to an interconnected control system and interconnected control method for a filter rod forming machine and a dust removal equipment. Background Technology
[0002] The filter rod forming workshop generates a large amount of fly filaments and dust during production. These pollutants not only severely damage the environmental hygiene of the production site but also adversely affect the health of on-site workers. To solve this pollution problem, existing technologies typically install a batch of dust removal equipment. The working principle of this type of dust removal equipment is to generate negative pressure to suck away the fly filaments and dust generated during the operation of the filter rod forming machine through dedicated pipelines. Then, a water curtain dust removal method is used to treat the sucked-in pollutants, thereby achieving the purpose of purifying the production environment.
[0003] Because dust collection equipment is large, it cannot be directly installed in the production workshop. A dedicated dust collection room is typically required to house the equipment. The dust collection equipment is connected to the filter rod forming machines in the production workshop via pipes spanning multiple floors to extract pollutants. In the current configuration, one dust collection unit is responsible for the dust collection work of two filter rod forming machines. However, there is no electrical signal interconnection between the dust collection unit and the filter rod forming machines, making automatic linkage control between the two impossible.
[0004] Based on the above issues, the shift leader needs to frequently travel between the production workshop and the dust collection room each day to manually start the corresponding dust collection equipment according to the filter rod forming machine number actually started that day. Furthermore, because filter rod forming machines frequently change numbers and stop mid-production, failure to promptly shut down the corresponding dust collection equipment results in it operating ineffectively, causing significant energy waste and ultimately leading to excessively high overall energy consumption in the workshop. In addition, the dust collection room is far from the production workshop, and frequent back-and-forth operations by employees not only significantly increase workload but also reduce production efficiency. Manual operation is also prone to omissions and delays, further affecting dust collection effectiveness and energy consumption control accuracy.
[0005] To address the shortcomings of existing technologies, directly connecting the filter rod forming machine and dust removal equipment via electrical wiring for control is extremely labor-intensive due to their different floor locations. Furthermore, electrical signals attenuate over long distances, leading to control signal distortion and failure, thus failing to meet actual production needs. Therefore, there is an urgent need to develop an interconnected control solution that can resolve these issues, enabling intelligent linkage between the filter rod forming machine and dust removal equipment, thereby reducing employee workload and workshop energy consumption.
[0006] To address the above problems, this invention is proposed. Summary of the Invention
[0007] This invention addresses the problem of increased workload and excessive energy consumption in the workshop caused by the lack of electrical interconnection between dust removal equipment and filter rod forming machines. It develops an IoT-based intelligent control system that connects the forming machine and dust removal equipment through the factory's server, enabling intelligent control. The invention collects the operating signals of the forming machine into the factory's server database and then transmits these signals to the PLC in the dust removal room as input. The PLC automatically starts the corresponding dust removal equipment based on the forming machine's operating unit number.
[0008] This invention discloses an interconnected control system and method for a filter rod forming machine and a dust removal device. The interconnected control system includes a filter rod forming machine, a switch, a server, a Beckhoff PLC, and the dust removal device. The filter rod forming machine, server, and Beckhoff PLC are all connected to the switch via network cables to achieve data interaction. The Beckhoff PLC is electrically connected to the dust removal device and is used to control the start and stop of the dust removal device. The server is used to collect the operating signals of the filter rod forming machine and transmit the operating signals to the Beckhoff PLC. The Beckhoff PLC is used to receive the operating signals of the filter rod forming machine transmitted by the server and control the start and stop of the corresponding dust removal device according to the operating signals. This invention realizes intelligent linkage control between the filter rod forming machine and the dust removal device, eliminating the need for manual operation of the dust removal device by employees, significantly reducing the workload of employees, improving the convenience and efficiency of production operations, and avoiding the problems of untimely dust removal or ineffective energy consumption caused by omissions or delays in manual operation.
[0009] This invention is achieved through the following technical solution:
[0010] The first aspect of this invention provides an interconnection control system for a filter rod forming machine and a dust removal device, comprising a filter rod forming machine, a switch, a server, a PLC, and a dust removal device; the filter rod forming machine, the server, and the PLC are all connected to the switch via network cables to achieve data interaction; the PLC is electrically connected to the dust removal device and is used to control the start and stop of the dust removal device; the server is used to collect the operating signals of the filter rod forming machine and transmit the operating signals to the PLC; the PLC is used to receive the operating signals of the filter rod forming machine transmitted by the server and control the start and stop of the corresponding dust removal device according to the operating signals.
[0011] PLC refers to Programmable Logic Controller, and the PLC used in this invention is Beckhoff PLC.
[0012] Preferably, the configuration ratio of the filter rod forming machine to the dust removal equipment is 2:1, that is, one dust removal equipment is responsible for the dust removal work of two filter rod forming machines; the PLC is a new device, while the filter rod forming machine, the switch, the server, and the dust removal equipment are all existing equipment in the factory.
[0013] Preferably, the PLC is configured with the ADS protocol, and the server establishes a communication connection with the PLC through the ADS protocol to realize bidirectional transmission of the operating signals of the filter rod forming machine. The ADS protocol (Automation Device Specification) is an open and widely used industrial communication protocol that enables Windows applications to exchange data with PLCs (Programmable Logic Controllers) at high speed, and is an indispensable part of automation control systems.
[0014] Preferably, the dust removal equipment is installed in a dedicated dust removal room, and the filter rod forming machine is installed in the production workshop. The two are connected by a pipeline to extract the fly filaments and dust generated by the filter rod forming machine.
[0015] Preferably, the dust removal equipment and the filter rod forming machine are located on different floors, and the two are connected by a pipe that spans the floors.
[0016] Preferably, the server is equipped with a Python script written using the pyads library, which is used to collect the operating signals of the filter rod forming machine, transmit the collected operating signals to the database of the server, and push the operating signals to the PLC.
[0017] Preferably, the dust removal equipment does not have a manual start or stop button; instead, it is automatically controlled by the PLC, receiving output signals from the PLC and executing start or stop actions. The electrical control circuit of the dust removal equipment has been modified, eliminating the original manual start or stop button and replacing it with automatic control by the PLC, receiving output signals from the PLC and executing start or stop actions.
[0018] A second aspect of the present invention provides an interconnection control method for a filter rod forming machine and a dust removal device, applied to the interconnection control system for the filter rod forming machine and the dust removal device described in the first aspect of the present invention. The method includes the following steps:
[0019] Step 1: Configure the ADS protocol of the PLC to establish a connection between the PLC and the switch via a network cable, and to achieve communication interconnection between the PLC and the server via the switch; modify the existing electrical control circuit of the dust removal equipment, switch the manual control mode of the dust removal equipment to the PLC automatic control mode, and establish an electrical connection between the output terminal of the PLC and the electrical control terminal of the dust removal equipment.
[0020] Step 2: Deploy a Python script written using the Pythonpyads library on the server. Use the Python script to collect the operating signals of each filter rod forming machine in the production workshop, including the machine start signal, stop signal and machine number information, and store the collected operating signals in the database of the server.
[0021] Step 3: The Python script extracts the operating signal of the filter rod forming machine from the database of the server, and transmits the operating signal to the PLC through the ADS protocol as the input signal of the PLC;
[0022] Step 4: Write a control program on the PLC. Based on the 2:1 correspondence between the filter rod forming machine and the dust removal equipment, set the control logic as follows: When at least one of the two filter rod forming machines corresponding to one dust removal equipment is in operation, the PLC outputs a start signal to control the dust removal equipment to start and maintain operation; when both filter rod forming machines corresponding to one dust removal equipment are in a stopped state, the PLC outputs a stop signal to control the dust removal equipment to shut down.
[0023] Step 5: The PLC receives the operating signal of the filter rod forming machine transmitted by the server in real time, and automatically outputs the corresponding control signal according to the preset control logic to control the start and stop of the dust removal equipment, thereby realizing the intelligent linkage control between the filter rod forming machine and the dust removal equipment.
[0024] Preferably, in step 2, the Python script collects the operating signals of the filter rod forming machine in real time. When the filter rod forming machine experiences status changes such as changing numbers or stopping midway, the script updates the operating signals in the database of the server in real time and pushes them to the PLC simultaneously, ensuring that the PLC obtains the latest operating status of the filter rod forming machine in a timely manner.
[0025] Preferably, in step 4, the control program of the PLC corresponds to the number of each dust removal device and matches it one-to-one with the machine number of the filter rod forming machine, so as to ensure the accuracy of the corresponding control between the dust removal device and the filter rod forming machine and avoid control misalignment problems.
[0026] Compared with the prior art, the present invention has the following beneficial effects:
[0027] 1. It completely solves the technical defect of the lack of electrical interconnection and control between the existing filter rod forming machine and the dust removal equipment, and realizes the intelligent linkage control between the two. It eliminates the need for employees to frequently travel between the production workshop and the dust removal room to manually operate the dust removal equipment, which greatly reduces the workload of employees, improves the convenience and efficiency of production operation, and avoids the problem of untimely dust removal or ineffective energy consumption caused by omissions or delays in manual operation.
[0028] 2. Precise scheduling and control of dust removal equipment has been achieved. Based on the configuration of one dust removal device corresponding to two filter rod forming machines, the dust removal device will automatically start as long as one of the two filter rod forming machines is running. When both filter rod forming machines stop running, the dust removal device will automatically shut down. This effectively avoids the waste of electricity caused by the ineffective operation of the dust removal device, significantly reduces the overall energy consumption of the workshop, achieves the goal of energy saving and consumption reduction, and reduces production and operating costs.
[0029] 3. By utilizing existing hardware resources in the factory, such as servers, switches, molding machines, and dust removal equipment, the system can be built by adding only one Beckhoff PLC. There is no need for large-scale modification of existing production equipment and infrastructure, which greatly reduces the cost and workload of system modification. Moreover, the modification process is simple and will not have a significant impact on the existing production schedule, making it easy to promote and apply.
[0030] 4. By using the ADS protocol to communicate between the server and Beckhoff PLC, the traditional direct electrical wiring control method is replaced. This effectively solves the problems of complicated wiring and signal attenuation caused by the filter rod forming machine and dust removal equipment being located on different floors. It ensures the stability and accuracy of control signal transmission, improves the reliability of system control, and avoids control failure caused by signal distortion.
[0031] 5. The electrical control circuit of the existing dust removal equipment was upgraded, and the manual control buttons were switched to PLC automatic control, realizing the intelligent upgrade of the dust removal equipment control mode. Combined with the data acquisition and transmission function of Python script, the real-time acquisition, transmission and processing of the filter rod forming machine's operating signals were realized. The PLC can adjust the working status of the dust removal equipment in real time according to the operating status of the forming machine, further improving the dust removal effect and the accuracy of energy consumption control, optimizing the production site environment and protecting the health of employees.
[0032] This invention enables interconnection and intelligent control between dust removal equipment and filter rod forming machines. Through automated control of interconnected equipment, it reduces employee workload and improves work efficiency; it also reduces energy consumption and production costs by leveraging IoT technology; furthermore, it supports enterprises' digital energy transformation, is applicable to various application scenarios, and solves the problem of data silos among some workshop equipment by connecting dust removal equipment to the enterprise network for monitoring. Therefore, the key to this invention lies in the system and method for achieving interconnection and intelligent control between dust removal equipment and filter rod forming machines using IoT technology, and in the control of the entire system via a PLC.

[0042] Example
[0043] This embodiment provides an interconnection control system for a filter rod forming machine 1 and a dust removal device 5, which includes a filter rod forming machine 1, a switch 2, a server 3, a Beckhoff PLC 4, and a dust removal device 5.

[0047] The dust removal equipment 5 and the filter rod forming machine 1 are located on different floors, and the two are connected by a pipe that spans the floors.
[0048] The server 3 is equipped with a Python script written using the pyads library. The script is used to collect the operating signals of the filter rod forming machine 1 and transmit the collected operating signals to the database of the server 3. At the same time, the operating signals are pushed to the Beckhoff PLC 4.
[0049] The dust removal equipment 5 does not have a manual start or stop button; instead, it is automatically controlled by the Beckhoff PLC 4. The equipment receives output signals from the Beckhoff PLC 4 and executes start or stop actions. The electrical control circuit of the dust removal equipment 5 has been modified, eliminating the original manual start or stop button and replacing it with automatic control via the Beckhoff PLC 4.
[0050] This embodiment also provides an interconnection control method between the filter rod forming machine 1 and the dust removal equipment 5, applied to the interconnection control system between the filter rod forming machine 1 and the dust removal equipment 5 described in this embodiment. The method includes the following steps:
[0051] Step 1: Configure the ADS protocol of the Beckhoff PLC4 to establish a connection between the Beckhoff PLC4 and the switch 2 via a network cable, and to achieve communication interconnection between the switch 2 and the server 3; modify the existing electrical control circuit of the dust removal equipment 5, switch the manual control mode of the dust removal equipment 5 to the automatic control mode of the Beckhoff PLC4, and establish an electrical connection between the output terminal of the Beckhoff PLC4 and the electrical control terminal of the dust removal equipment 5;
[0052] Step 2: Deploy a Python script written using the Pythonpyads library on the server 3. Use the Python script to collect the operating signals of each filter rod forming machine 1 in the production workshop, including the start signal, stop signal and machine number information of the forming machine 1, and store the collected operating signals in the database of the server 3.
[0053] Step 3: The Python script extracts the operating signal of the filter rod forming machine 1 from the database of the server 3, and transmits the operating signal to the Beckhoff PLC4 via the ADS protocol as the input signal of the Beckhoff PLC4;
[0054] Step 4: Write a control program on the Beckhoff PLC4. Based on the 2:1 correspondence between the filter rod forming machine 1 and the dust removal equipment 5, set the control logic as follows: When at least one of the two filter rod forming machines 1 corresponding to one dust removal equipment 5 is in operation, the Beckhoff PLC4 outputs a start signal to control the dust removal equipment 5 to start and maintain operation; when both filter rod forming machines 1 corresponding to one dust removal equipment 5 are in a stopped state, the Beckhoff PLC4 outputs a stop signal to control the dust removal equipment 5 to shut down.
[0055] Step 5: The Beckhoff PLC4 receives the operating signal of the filter rod forming machine 1 transmitted by the server 3 in real time, and automatically outputs the corresponding control signal according to the preset control logic to control the start and stop of the dust removal equipment 5, thereby realizing the intelligent linkage control between the filter rod forming machine 1 and the dust removal equipment 5.
[0056] Preferably, in step 2, the Python script collects the operating signals of the filter rod forming machine 1 in real time. When the filter rod forming machine 1 experiences status changes such as changing numbers or stopping midway, the operating signals in the database of the server 3 are updated in real time and pushed to the Beckhoff PLC 4 simultaneously to ensure that the Beckhoff PLC 4 obtains the latest operating status of the filter rod forming machine 1 in a timely manner.

[0058] Specifically, such as Figure 1 As shown, this invention mainly consists of a molding machine 1, a switch 2, a server 3, a PLC 4, and a dust removal device 5. Only the PLC 4 needs to be added; the other devices are readily available. The main task is to achieve interconnected control. A Python script is written using the Python pyads library and deployed to the cloud server 3. The Beckhoff PLC 4 is configured with the ADS protocol to communicate with the server 3, collecting operating signals from the molding machine 1 and transmitting the equipment's operating signals back to the Beckhoff PLC 4. A new Beckhoff PLC 4 is added to the dust removal room, its input signal coming from the operating signals of the filter rod molding machine 1 in the server 3, and connected to the server 3 via a network cable and switch 2. The Beckhoff PLC 4 is programmed to directly control the start and stop of the dust removal device 5. The existing electrical control circuit of the dust removal device 5 is modified, transforming the manual buttons into automatic control via the Beckhoff PLC 4. Through the above work, the dust removal device 5 can be intelligently scheduled based on the number of molding machines 1 in operation. Since one dust collector 5 is responsible for two molding machines 1, if either of these two machines is running, the dust collector 5 must be turned on. The PLC4 program flowchart is shown in Figure 2. Figure 2After the program starts, the operating status of the six filter rod forming machines 1 is monitored simultaneously, following the linkage rule of two filter rod forming machines 1 corresponding to one dust removal device 5: when forming machine 1 or 2 is turned on, dust removal device 1 is automatically started; when forming machine 3 or 4 is turned on, dust removal device 2 is automatically started; when forming machine 5 or 6 is turned on, dust removal device 3 is automatically started; when forming machine 7 or 8 is turned on, dust removal device 4 is automatically started; when forming machine 9 or 10 is turned on, dust removal device 5 is automatically started; when forming machine 11 or 12 is turned on, dust removal device 6 is automatically started. After all the start commands of dust removal devices 5 have been executed, the current program flow ends.
