Description

Technical Field

[0001] The present invention belongs to the technical field of filter rod forming machines, and in particular relates to a method, a device and a medium for monitoring the operating status of a cutter disc of a filter rod forming machine. Background Art

[0002] The filter rod forming machine is used to produce filter rods for cigarettes. It has a long continuous operation time and high operating temperature. The filter rod forming machine cuts the filter rods into filter rods of specified length. In order to meet the requirements of cigarette rolling and splicing, the cuts of the cut filter rods must be flat and free of burrs. When the filter rod forming machine is running, the cutter disc maintains a high-speed and high-temperature operation state. At the same time, the flying flowers and dust generated when the filter rods are cut can easily induce fatigue and failure of the rolling bearings at the cutter disc.

[0003] When various situations occur, the cutter disc is disassembled and checked one by one to determine the failed rolling bearing. After replacement, the cutter disc is reset to the filter rod forming machine, and then the repair situation is tracked. Among them, various situations are: the filter rod has quality risks such as rough cutting and bevel cutting; abnormal noise occurs in the cutter disc; and regular maintenance is required.

[0004] The traditional method of disassembling and inspecting rolling bearings has the following limitations: the filter rod forming machine has a complex structure, and the operation of the cutter disc cannot be directly observed; the cutter disc operation indicators and data cannot be quantified and evaluated; the cutter disc operation indicators and data cannot be recorded and analyzed for a long time. These factors have led to the current filter rod forming machine adopting a post-fault repair strategy for each disc.

[0005] The installation space of the filter rod forming machine's cutter disc is compact, and disassembly and installation are time-consuming and laborious; there are a large number of mating surfaces on the cutter disc, and high assembly precision is required; the cutter disc needs to be comprehensively and carefully inspected to check for damage, wear, looseness, etc. of each part, and these factors cause maintenance to take a relatively long time.

[0006] The disassembly, installation, inspection and adjustment of the filter rod forming machine blade disc need to be done manually, and require experienced technicians to operate and judge; disassembly will cause damage to the undamaged parts and need to be replaced simultaneously; installation, disassembly and inspection require downtime maintenance; after maintenance, a dedicated person is required to continuously track the repair status and other factors, resulting in relatively high maintenance costs.

[0007] Inspection and maintenance results are affected by the operator's experience and ability and lack objectivity; it is impossible to effectively detect initial damage or failures. Summary of the invention

[0028] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present disclosure unless otherwise specifically stated.

[0029] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present disclosure, its application, or uses.

[0030] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0031] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0032] like Figure 1 As shown, the method for monitoring the operating status of a cutter disc of a filter rod making machine includes steps 110 to 130.

[0033] In step 110, the vibration of the cutter disc is monitored in real time by means of a vibration sensor installed at the cutter disc of the filter rod making machine to obtain a real-time vibration signal.

[0034] In step 120, the real-time vibration signal is input into a large model for monitoring the operation status of the cutterhead.

[0035] In step 130, when it is monitored that the health factor mapped by the real-time vibration signal is greater than the health factor threshold, a cutter head fault warning is issued.

[0036] In the present disclosure, a quantitative evaluation of the operating state of a cutter disc of a filter rod forming machine is achieved by obtaining a vibration signal installed at the cutter disc of the filter rod forming machine, filtering and denoising the vibration signal, and extracting the time domain and frequency domain features contained in the signal to characterize the operating state of the cutter disc.

[0037] The faulty bearing at the cutter disc of the filter rod forming machine can be determined without disassembling the cutter disc. Vibration signals are obtained by installing multiple vibration sensors at the cutter disc of the filter rod forming machine. The installation positions of the vibration sensors and the differences in the inherent properties of the bearings at the cutter disc, such as bearing type, inner diameter, outer diameter and number of rollers, are combined with the different positions of the sensors and the cutter disc and the different information contained in the signals. The faulty bearing can be determined without disassembling the cutter disc.

[0038] The operating status of the cutter disc of the filter rod forming machine is monitored. As the operating time accumulates, the operating status of the bearing at the cutter disc will change, the amplitude of the vibration signal will increase accordingly, and the frequency and other information will also change. The acquired vibration signal is stored by the computer, and the stored data can record the signal generated by the operation to characterize the current operating status of the equipment. Using the monitoring data, signal processing, deep learning and other methods are used to remove irrelevant components in the data and mine the equipment operating status information contained in the monitoring data to realize the monitoring and recording of the operating status.

[0039] The fault diagnosis and prediction of the cutter disc of the filter rod forming machine is realized. The health factor is constructed by building a model to characterize the operating status of the cutter disc, and a corresponding relationship model between the state change characteristics of the vibration signal and the operating status of the cutter disc is established. The state of the cutter disc is quickly obtained according to the collected vibration signal, and the fault diagnosis of the cutter disc is performed in real time. At the same time, the collected vibration signal change trend and historical data are combined to realize early prediction of faults, which is conducive to timely maintenance and replacement.

[0040] like Figure 2 , Figure 3 As shown, vibration sensor installation: select vibration sensors that meet the sampling rate and are easy to fix and arrange them at the vertical or horizontal position of the monitored bearings and other key components at the cutter disc. Among them, the relative position of each vibration sensor and the cutter disc is different; specifically, when the filter rod forming machine is working, the cutter disc set in the filter rod forming machine cuts the filter rods through rotational motion, and the vibration of the cutter disc can be monitored by using multiple vibration sensors installed at the cutter disc. The vibration signal contains information about the working status of the cutter disc. At the same time, due to the different relative positions of each vibration sensor and the cutter disc, and the inherent properties of each bearing, such as: bearing type, inner diameter, outer diameter and number of rollers, multiple sensors can fully reflect the operating status of the cutter disc.

[0041] Figure 3 The diagram is a schematic diagram of the cutter disc structure and sensor installation of the forming machine. Mark 1 represents the cutter disc, mark 2 represents the bearing seat, mark 3 represents the piston, mark 4 represents the feed push rod, mark 5 represents the pawl, mark 6 represents the ratchet, mark 7 represents the worm, mark 8 represents the worm wheel, mark 9 represents the tool holder, mark 10 represents the cutter, mark 11 represents the unlocking pin, mark 12 represents the pressure roller, and mark 13 represents the vibration sensor. Multiple vibration sensors installed at the cutter disc collect vibration signals.

[0042] The data is transmitted to the local computer through the industrial Internet for storage. Data storage can continuously record the signal samples generated during operation to characterize the equipment, which can be used to establish the model and analyze the changes in the operation status of the cutter head as historical data. Figure 4 As shown in the figure, the vibration signal of the entire life cycle can be obtained through continuous collection and storage.

[0043] First, the time domain and frequency domain of the signal obtained from the cutter head are extracted through feature engineering, and then the better features are selected through feature evaluation and selection to form a feature vector. Specifically, the vibration signal is first subjected to noise reduction and filtering, and then the time domain features and frequency domain features in the vibration signal are extracted; the time domain features and frequency domain features in the vibration signal are then standardized and normalized, and then fused to obtain the signal feature matrix of the cutter head. The better features should show a strong correlation with the operating status, such as Figure 5 As shown in the features (a) to (f) screened out in the figure, these features become larger or smaller in relation to the operating state as the operating state deteriorates.

[0044] Secondly, the feature vector is divided into training data and test data. The training data is composed of the data of some healthy stages in the signal; the training data is selected for analysis and processing to determine the characteristics of the healthy stage data, such as size, change speed, frequency components, etc. Finally, the model is constructed and the training data is used to train the model on the local computer.

[0045] The sensor installed at the cutter disc transmits the cutter disc operation data back to the local computer in real time. The computer identifies unhealthy stage data through the trained model and issues an early warning.

[0046] First, the model is trained using training data. Then, the operating data is input into the model. When the model determines that the health factor mapped by the current operating data of the cutter head is lower than the threshold, the current cutter head is in the healthy stage; when the model determines that the health factor mapped by the current operating data of the cutter head is higher than the threshold, the current cutter head is in the degraded stage. Figure 6 At the same time, the model can be trained through the operation data of various fault stages collected in the early stage, and then more accurate fault information diagnosis and prediction can be achieved through the model. Figure 7 As shown, c0 to c6 represent different operating states. The model can identify that the information contained in the current cutter head operating data is closer to the states of c0 to c6, so as to realize the fault information diagnosis and prediction of the cutter head.

[0047] Finally, when the model identifies unhealthy data, it issues an early warning. The early warning information is pushed to other mobile terminals and clients through the industrial Internet. Based on the early warning information, maintenance plans or measures can be formulated in advance.

[0048] In this method, the quantitative evaluation of the operation status of the cutter disc of the filter rod forming machine is realized, and the computer can continuously record the operation to generate signals for characterizing the equipment; the vibration signal is obtained by installing multiple vibration sensors at the cutter disc of the filter rod forming machine, and the faulty bearing at the cutter disc of the filter rod forming machine is determined without disassembling the cutter disc, combining the installation position of the vibration sensor and the difference in the inherent properties of the bearing at the cutter disc, which reduces the maintenance time and reduces the maintenance cost; the health factor is constructed by building a model to characterize the operation status of the cutter disc, and a corresponding relationship model between the state change characteristics of the vibration signal and the operation status of the cutter disc is established. The state of the cutter disc is quickly obtained according to the collected vibration signal, and the fault diagnosis of the cutter disc is carried out in real time; the early prediction and early warning of the fault are realized by analyzing the change trend and historical data of the vibration signal. The early warning information is pushed to other mobile terminals and clients through the industrial Internet, which is conducive to timely maintenance and replacement of the cutter disc of the forming machine.
