Description

Technical Field

[0001] The present invention relates to the technical field of cigarette packaging machinery and equipment, and particularly to a servo motor cleaning method and system based on a trimming cutter head of a cigarette machine. Background Art

[0002] With the rapid development of the technical field of cigarette packaging machinery and equipment, the trimming cutter head device of the cigarette machine has gradually changed from the original mechanical drive to a servo motor drive. However, since the gap at the connection between the servo motor shaft and the trimming cutter head is extremely easy to enter cigarette ash, after long-term operation, it is very easy to cause the servo motor to rotate inflexibly or even jam.

[0003] However, when the servo motor rotates inflexibly or even jams, the rotation of the trimming cutter head is blocked, resulting in the trimming cutter head being unable to rotate normally, affecting the weight adjustment effect of the cigarette. In severe cases, the motor jamming may trigger the protection mechanism of the equipment, causing the cigarette machine to stop, interrupting the production process, and reducing the production efficiency. And after the stop, it takes time to troubleshoot and repair the fault, further affecting the production progress. At the same time, the cigarette ash jamming the servo motor may cause the motor to operate overloaded, increasing the risk of damage to the servo motor. If the servo motor is damaged, it needs to be repaired or replaced, increasing the equipment maintenance cost. Therefore, it becomes very important to clean the servo motor in a timely manner.

[0004] In the prior art, the servo motor is usually cleaned and maintained by manual cleaning. However, if the manual cleaning method is used, the operator needs to clean and maintain the equipment more frequently, increasing the labor cost and time cost, and reducing the operating efficiency of the servo motor. Therefore, how to effectively clean the cigarette ash in the gap between the servo motor shaft of the trimming cutter head of the cigarette machine and the trimming cutter head, reduce the failure rate caused by the accumulation of cigarette ash jamming the servo motor, and improve the working efficiency of the servo motor is an urgent problem to be solved at present. Summary of the Invention

[0005] The present invention provides a servo motor cleaning method and system based on a trimming cutter head of a cigarette machine, which can solve the problem of low cleaning efficiency of the cigarette ash in the gap between the servo motor shaft of the trimming cutter head of the cigarette machine and the trimming cutter head.

[0006] According to one aspect of the present invention, a servo motor cleaning method based on a trimming cutter head of a cigarette machine is provided, including:

[0009] The cleaning blower mechanism performs a cleaning operation on the servo motor corresponding to the target feeding and ribbon-making machine based on a preset air pressure and a preset execution time.

[0010] According to another aspect of the present invention, there is provided a servo motor cleaning system based on a trimming cutter head of a cigarette making machine, including:

[0012] The control relay is configured to receive the output signal, control the cleaning solenoid valve to start running based on the output signal, and send a preset air pressure to the cleaning blower mechanism through the cleaning solenoid valve;

[0013] The cleaning blower mechanism performs a cleaning operation on the servo motor corresponding to the target feeding and ribbon-making machine based on a preset air pressure and a preset execution time.

[0014] The technical solution of the embodiment of the present invention is that the programmable logic controller receives the operation signal corresponding to the target feeding and ribbon-making machine, generates an output signal based on the operation signal, and sends the output signal to the control relay. Furthermore, the control relay receives the output signal, controls the cleaning solenoid valve to start running based on the output signal, and sends a preset air pressure to the cleaning blower mechanism through the cleaning solenoid valve. Finally, the cleaning blower mechanism performs a cleaning operation on the servo motor corresponding to the target feeding and ribbon-making machine based on a preset air pressure and a preset execution time. Since the cleaning blower mechanism is used to clean the soot in the gap between the servo motor shaft of the trimming cutter head of the cigarette making machine and the trimming cutter head based on a preset air pressure and a preset execution time, the problem of low cleaning efficiency of the soot in the gap between the servo motor shaft of the trimming cutter head of the cigarette making machine and the trimming cutter head is solved, the soot in the gap between the servo motor shaft of the trimming cutter head of the cigarette making machine and the trimming cutter head can be effectively cleaned, the failure rate caused by the jamming of the servo motor due to the accumulation of soot is reduced, and the working efficiency of the servo motor is improved.

[0022] Embodiment 1

[0023] Figure 1 It is a flowchart of a servo motor cleaning method based on a trimming cutter head of a cigarette making machine provided in Embodiment 1 of the present invention. This embodiment is applicable to the situation of cleaning the soot in the gap at the connection between the servo motor shaft of the trimming cutter head of the cigarette making machine and the trimming cutter head. This method can be executed by a servo motor cleaning system based on the trimming cutter head of the cigarette making machine, and the servo motor cleaning system based on the trimming cutter head of the cigarette making machine can be implemented in the form of hardware and / or software. As Figure 1 shown, the method includes:

[0024] S110. Receive the operation signal corresponding to the target feeding and ribbon-forming machine through a programmable logic controller, generate an output signal based on the operation signal, and send the output signal to a control relay.

[0025] Among them, a programmable logic controller (PLC) can refer to a digital computing operation electronic system designed for industrial environments. Generally, a PLC uses a programmable memory to store and execute instructions such as logical operations, sequential control, timing, counting, and arithmetic operations, and controls various mechanical equipment or production processes through digital or analog inputs and outputs. A feeding and ribbon-forming machine can refer to a device that sorts and quantifies the cut tobacco processed in the previous process to form a uniform and continuous cut tobacco strip. Generally, a feeding and ribbon-forming machine consists of components such as a hopper, a quantitative feeding device, a suction wire forming device, a fan system, and a transmission system. The suction wire forming device includes a trimming cutter head. The target feeding and ribbon-forming machine can refer to the feeding and ribbon-forming machine included in a cigarette machine that needs to clean the servo motor.

[0026] Among them, the operation signal can refer to an action signal generated when the target feeding and ribbon-forming machine starts to operate. Generally, when the cigarette machine to which the target feeding and ribbon-forming machine belongs is in production operation, the corresponding target feeding and ribbon-forming machine automatically generates an operation signal. The output signal can refer to a signal used to output the result of program execution and drive external devices. Generally, the output signal can be used to control the on / off state of external devices.

[0027] S120. Receive the output signal through the control relay, control the cleaning solenoid valve to start operating based on the output signal, and send a preset air pressure to the cleaning blowing mechanism through the cleaning solenoid valve.

[0028] Among them, the control relay can refer to a relay that provides functions such as control, protection, and signal conversion. Generally, the control relay can drive the contact to act through the electromagnetic force generated by the electromagnetic coil, so as to realize functions such as automatic adjustment of the circuit, safety protection, and circuit conversion.

[0029] Among them, the cleaning solenoid valve can refer to a basic automation component for controlling fluids. Generally, the cleaning solenoid valve uses the magnetic force generated by electromagnetic induction to act on the magnetic core to make it attract or separate, thereby controlling the opening and closing of the valve and realizing the control of fluids. In the embodiments of the present invention, the cleaning solenoid valve is mainly used to control gases. The preset air pressure can refer to the atmospheric pressure acting on a unit area that is preset in advance. Generally, the preset air pressure can be a stable air pressure with a suitable magnitude. If the preset air pressure is too small, the cigarette ash cannot be blown off; if it is too large, it will affect the cut tobacco conveying and forming of the target feeding and ribbon-forming machine.

[0030] S130. Clean the servo motor corresponding to the target feeding and ribbon-forming machine through the cleaning blowing mechanism based on the preset air pressure and the preset execution time.

[0031] Among them, the cleaning and blowing mechanism may refer to a device for blowing away the soot in the gap between the servo motor shaft of the trimming cutter head of a cigarette making machine and the trimming cutter head. Usually, the cleaning and blowing mechanism can blow away the soot from the surface of the workpiece through a strong air flow to achieve the cleaning effect. Optionally, in the embodiment of the present invention, the cleaning and blowing mechanism is arranged on the side of the servo motor.

[0032] Among them, the preset execution time may refer to the execution cycle of the cleaning operation set in advance. Usually, it can be set according to the actual application requirements. In an optional implementation manner, before the cleaning and blowing mechanism cleans the servo motor corresponding to the target feeding and strip-forming machine based on the preset air pressure and the preset execution time, it further includes: determining the preset execution time corresponding to the cleaning and blowing mechanism by a programmable logic controller based on a preset execution mechanism. Among them, the preset execution mechanism may refer to the execution time setting rule set in advance. Exemplarily, the preset execution mechanism may be to set the preset execution time to execute once every hour. Thus, by setting the preset execution time through the PLC, the cleaning and blowing mechanism can be controlled to clean the servo motor at regular intervals, which not only ensures the cleaning effect but also avoids the problem of energy waste caused by long-term blowing.

[0033] The technical solution of the embodiment of the present invention is as follows: the programmable logic controller receives the operation signal corresponding to the target feeding and strip-forming machine, generates an output signal based on the operation signal, and sends the output signal to the control relay. Furthermore, the control relay receives the output signal, controls the cleaning solenoid valve to start running based on the output signal, and sends the preset air pressure to the cleaning and blowing mechanism through the cleaning solenoid valve. Finally, the cleaning and blowing mechanism cleans the servo motor corresponding to the target feeding and strip-forming machine based on the preset air pressure and the preset execution time. Since the cleaning and blowing mechanism is used to clean the soot in the gap between the servo motor shaft of the trimming cutter head of the cigarette making machine and the trimming cutter head based on the preset air pressure and the preset execution time, the problem of low cleaning efficiency of the soot in the gap between the servo motor shaft of the trimming cutter head of the cigarette making machine and the trimming cutter head is solved. It can effectively clean the soot in the gap between the servo motor shaft of the trimming cutter head of the cigarette making machine and the trimming cutter head, reduce the failure rate of the servo motor caused by the accumulation of soot and jamming, and improve the working efficiency of the servo motor.

[0034] Embodiment 2

[0035] Figure 2The flowchart of a servo motor cleaning method based on the trimming cutter head of a cigarette making machine provided in the second embodiment of the present invention. This embodiment is refined based on the above embodiment. Specifically in this embodiment, the operation of receiving the operation signal corresponding to the target feeding and strip-forming machine through the programmable logic controller and generating an output signal based on the operation signal, and sending the output signal to the control relay is refined. Specifically, it may include: receiving the operation signal through the input relay of the programmable logic controller; generating an output signal through the output relay of the programmable logic controller based on the operation signal of the input relay, and sending the output signal to the control relay. As Figure 2 shown, the method includes:

[0036] S210. Determine the operation signal corresponding to the target feeding and strip-forming machine based on the current state change information by the target feeding and strip-forming machine, and send the operation signal to the programmable logic controller.

[0037] Among them, the current state change information may refer to the change information between the current state and the previous state of the target feeding and strip-forming machine. Exemplarily, if the current state of the target feeding and strip-forming machine is the running state and the previous state of the target feeding and strip-forming machine is the stopped state, then the current state change information may be starting to run.

[0038] S220. Receive the operation signal through the input relay of the programmable logic controller.

[0039] Among them, the input relay may refer to the device in the programmable logic controller for receiving signals from external input devices.

[0040] S230. Generate an output signal through the output relay of the programmable logic controller based on the operation signal of the input relay, and send the output signal to the control relay.

[0041] Among them, the output relay may refer to the device in the programmable logic controller for outputting the execution result of the program and driving external devices.

[0042] S240. Receive the output signal through the control relay, and generate a connection signal based on the output signal.

[0043] Among them, the connection signal may refer to the power-on signal of the control relay. Exemplarily, the connection signal may be the signal of the coil being energized in the control relay.

[0044] S250. Control the cleaning solenoid valve to start running based on the connection signal through the control relay.

[0045] Specifically, after the output relay of the programmable logic controller generates an output signal based on the operating signal of the input relay and sends the output signal to the control relay, the control relay can energize the coil based on the output signal to generate a connection signal, and further drive the cleaning solenoid valve to act. Thus, an effective basis is provided for subsequent operations.

[0046] S260. The cleaning solenoid valve receives the preset air pressure corresponding to the target feeding and ribbon-forming machine based on the starting operation state of the cleaning solenoid valve, and sends the preset air pressure to the cleaning air-blowing mechanism.

[0047] Among them, the starting operation state can refer to the action state of the cleaning solenoid valve. Exemplarily, the starting operation state can be the actuated state and the unactuated state. Specifically, if the connection signal drives the cleaning solenoid valve to act, the starting operation state of the cleaning solenoid valve is the actuated state.

[0048] In an optional embodiment, before the cleaning solenoid valve receives the preset air pressure corresponding to the target feeding and ribbon-forming machine based on the starting operation state, it further includes: generating the preset air pressure corresponding to the target feeding and ribbon-forming machine by a pressure regulating valve based on a preset pressure regulating mechanism, and sending the preset air pressure to the cleaning solenoid valve. Among them, the pressure regulating valve can refer to a device that controls the gas flow by adjusting the pressure. The preset pressure regulating mechanism can refer to a preset pressure adjustment mechanism. Usually, the preset pressure regulating mechanism can be set according to actual application requirements.

[0049] Specifically, before the cleaning solenoid valve receives the preset air pressure corresponding to the target feeding and ribbon-forming machine based on the starting operation state, the preset air pressure corresponding to the target feeding and ribbon-forming machine can be generated in advance by the pressure regulating valve according to the preset pressure regulating mechanism. Thus, when the cleaning solenoid valve is in the actuated state, it can directly receive the preset air pressure and perform subsequent operations, improving the cleaning efficiency.

[0050] S270. The cleaning air-blowing mechanism determines the target execution time based on the current system time and the preset execution time.

[0051] Among them, the current system time can refer to a mechanism for recording and representing the current time. The target execution time can refer to the actual execution time obtained by converting based on the current system time and the preset execution time. Usually, the difference between the target execution time and the current system time is a multiple of the preset execution time. Exemplarily, if the current system time is nine o'clock and the preset execution time is once per hour, the target execution time can be ten o'clock.

[0052] S280. The cleaning air-blowing mechanism performs a cleaning operation on the servo motor corresponding to the target feeding and ribbon-forming machine based on the target execution time and the preset air pressure.

[0053] Specifically, after receiving the preset air pressure corresponding to the target feeding and ribbon-forming machine based on the start-up operation state of the cleaning solenoid valve and sending the preset air pressure to the cleaning air-blowing mechanism, the cleaning air-blowing mechanism can determine the target execution time based on the current system time and the preset execution time, and when the current system time reaches the target execution time, clean the servo motor corresponding to the target feeding and ribbon-forming machine based on the preset air pressure, so as to complete the cleaning of the soot in the gap between the servo motor shaft of the trimming cutter head of the cigarette machine and the trimming cutter head.

[0054] In the technical solution of the embodiment of the present invention, the target feeding and ribbon-forming machine determines the operation signal corresponding to the target feeding and ribbon-forming machine based on the current state change information and sends the operation signal to the programmable logic controller. Furthermore, the input relay of the programmable logic controller receives the operation signal, and the output relay of the programmable logic controller generates an output signal based on the operation signal of the input relay and sends the output signal to the control relay. Further, the control relay receives the output signal, generates a connection signal based on the output signal, and controls the start-up operation of the cleaning solenoid valve based on the connection signal through the control relay. Further, the cleaning solenoid valve receives the preset air pressure corresponding to the target feeding and ribbon-forming machine based on the start-up operation state of the cleaning solenoid valve and sends the preset air pressure to the cleaning air-blowing mechanism. Finally, the cleaning air-blowing mechanism determines the target execution time based on the current system time and the preset execution time, and cleans the servo motor corresponding to the target feeding and ribbon-forming machine based on the target execution time and the preset air pressure through the cleaning air-blowing mechanism. Since the cleaning air-blowing mechanism is used to clean the soot in the gap between the servo motor shaft of the trimming cutter head of the cigarette machine and the trimming cutter head based on the preset air pressure and the preset execution time, the problem of low cleaning efficiency of the soot in the gap between the servo motor shaft of the trimming cutter head of the cigarette machine and the trimming cutter head is solved, the soot in the gap between the servo motor shaft of the trimming cutter head of the cigarette machine and the trimming cutter head can be effectively cleaned, the failure rate caused by the jamming of the servo motor due to the accumulation of soot is reduced, and the working efficiency of the servo motor is improved.

[0055] Based on the above embodiment, the present invention provides an optional implementation manner. Specifically, when the cigarette machine is in production operation, the input relay of the PLC receives the operation signal corresponding to the target feeding and ribbon-forming machine, and the output relay of the PLC makes the control relay coil energized, so that the control relay drives the cleaning solenoid valve to act. At this time, the cleaning solenoid valve will connect to the stable preset air pressure of appropriate magnitude provided by the pressure regulating valve. A cleaning air-blowing mechanism is installed on the side of the servo motor, and the preset air pressure connected by the cleaning solenoid valve is used to clean the servo motor through the air-blowing holes on the side of the cleaning air-blowing mechanism.

[0056] It should be noted that when the target feeding and ribbon-forming machine stops running, the PLC will control the solenoid valve to close after a delay for a period of time to ensure that the residual tobacco in the servo motor is completely blown out.
