[0044] Figure 3 It is a schematic diagram of a temperature control reliability analysis interface provided by an embodiment of the present invention. Specific Embodiments

[0045] In order to enable those skilled in the art to better understand the solutions of the embodiments of the present invention, the following will further elaborate on the embodiments of the present invention in conjunction with the accompanying drawings and embodiments.

[0046] Aiming at the problems that the current cigarette beauty device for transparent paper shaping in cigarette production lacks status monitoring, resulting in unstable operation and untimely fault maintenance. The present invention provides a monitoring method for a cigarette beauty device, which solves the problems that the existing cigarette beauty device for transparent paper shaping lacks status monitoring, is prone to unstable equipment operation status and untimely fault maintenance, and can improve the reliability and operation efficiency of the cigarette beauty device.

[0047] As Figure 1 shown, a monitoring method for a cigarette beauty device includes:

[0048] S1: Conduct on-line temperature detection on the upper plane iron, upper side iron, right end face iron, left end face iron, lower side iron and lower plane iron of the cigarette beauty device, and record the temperature fluctuation degree and abnormal state frequency of each iron.

[0049] S2: Set temperature fluctuation thresholds in segments, and classify the fluctuation amplitudes of the temperatures of each iron compared with the set temperature thresholds from low to high;

[0050] S3: Set a temperature abnormality threshold, and determine that the temperature of the corresponding iron is abnormal when the temperature fluctuation of each iron is greater than the temperature abnormality threshold;

[0051] S4: Obtain the duration and number of abnormalities of the temperature of each iron in each interval to form a temperature monitoring record table;

[0052] S5: Conduct a reliability evaluation on each iron according to the temperature monitoring record table to determine whether each iron is in a reliable state, a minor hidden danger state, a serious hidden danger state or a fault state.

[0053] Specifically, as Figure 2 shown, the beauty device includes: an upper planar soldering iron 1, an upper side soldering iron 2, a right end face soldering iron 3, a left end face soldering iron 4, a lower planar soldering iron 5, a lower side soldering iron 6, a bracket 7, a device side protective cover 8, a cigarette bar pushing rod 9, a push rod motion detector 10, an inlet cigarette bar detector 11, a cigarette bar in-place detector 12, a downward pressing motion detector 13, and an outlet cigarette bar detector 14. The cigarette bar is fed into the beauty station through the cigarette bar pushing channel 15 and conveyed out through the cigarette bar pushing-out channel 16. During cigarette bar beautification, the real-time temperature of the six beauty station soldering iron assemblies is collected online. The temperature value of each station is compared and calculated with the expected temperature set value inside the controller, the current temperature control fluctuation state is recorded, and the abnormal temperature control states are classified into multiple levels for classification and statistics. Then, maintenance suggestions are given based on the temperature fluctuation data. It can solve the problems that the existing beauty device for shaping the transparent paper of cigarette bars lacks status monitoring, which is likely to cause unstable operation status of the equipment and untimely fault maintenance, and can improve the reliability and operation efficiency of the cigarette bar beauty device.

[0054] Further, the interval classification of the fluctuation amplitude of comparing the temperature of each soldering iron with the set temperature threshold from low to high includes:

[0055] The temperature fluctuation state is divided into four levels: A, B, C, and S. When the fluctuation amplitude of the temperature of each soldering iron is greater than 5% and less than 8%, it is in state A.

[0056] When the fluctuation amplitude is greater than 8% and less than 10%, it is in state B.

[0057] When the fluctuation amplitude is greater than 10% and less than 20%, it is in state C.

[0058] When the fluctuation amplitude is greater than 20%, it is in state S.

[0059] Further, the obtaining of the duration and the number of abnormalities of the temperature of each soldering iron in each interval includes:

[0060] Obtain the duration of the temperature detected by each soldering iron in state A, state B, state C, or state S.

[0061] And take the number of times that the temperature fluctuation amplitude of each soldering iron detected is in state S as the number of abnormalities.

[0062] In practical applications, the temperature control abnormal state A means that the monitored temperature value fluctuates by more than 5% and less than 8% compared with the set temperature value. The cumulative duration of this state is statistically analyzed and recorded.

[0063] The abnormal temperature control B state means that the monitored temperature value fluctuates by more than 8% and less than 10% compared with the set temperature value. The cumulative duration of this state is statistically analyzed and recorded.

[0064] The abnormal temperature control C state means that the monitored temperature value fluctuates by more than 10% and less than 20% compared with the set temperature value. The cumulative duration of this state is statistically analyzed and recorded.

[0065] The abnormal temperature control S state means that the monitored temperature value fluctuates by more than 20% and the duration does not exceed 1 second compared with the set temperature value. This state is mostly caused by the accidental mutation of the temperature measurement value of the thermocouple. Due to the short duration, it is difficult for users to observe the phenomenon. For state S, record the number of abnormal occurrences and the maximum temperature fluctuation value reached by the mutation.

[0066] Furthermore, according to the temperature monitoring record form, the reliability evaluation of each surface soldering iron is carried out, including:

[0067] Obtain the lowest temperature value, the highest temperature value of each surface soldering iron, and the durations in states A, B, C, and S according to the temperature monitoring record form;

[0068] According to the reliability analysis empirical formula: Calculate the reliability evaluation score, where C represents the reliability evaluation score, T 0 represents the total daily operating time of the beauty device, T1 represents the cumulative value of the time in state A, T 2 represents the cumulative value of the time in state B, T 3 represents the cumulative value of the time in state C, X represents the number of abnormalities, and α 1 ~α 3 correspond to the different weight coefficients assigned to states A, B, and C of the temperature control state respectively.

[0069] Furthermore, determining that each surface soldering iron is in a reliable state, a minor hidden danger state, a serious hidden danger state, or a failure state includes:

[0070] When the reliability evaluation score C satisfies C≥95, judge the current state as a reliable state;

[0071] When 80≤C<95, judge the current state as a minor hidden danger state;

[0072] When 60≤C<80, judge the current state as a serious hidden danger state;

[0073] When C<60, judge the current state as a failure state.

[0074] In practical applications, recommendations for use and maintenance are provided based on the temperature reliability evaluation results. For the reliable state, the corresponding maintenance recommendation is to perform daily cleaning without additional repair activities. For the minor hidden danger state, the corresponding maintenance recommendation is to conduct a key inspection during the weekly maintenance stage to confirm whether repair activities such as replacing spare parts are required. For the major hidden danger state, the corresponding maintenance recommendation is to immediately carry out repair activities such as replacing parts at the corresponding location during the next weekly maintenance stage to eliminate equipment hidden dangers. For the failure state, the corresponding recommendation is to immediately stop the machine for emergency repair activities to quickly eliminate the failure and avoid greater losses. Among them, the analysis result display interface can be as Figure 3 shown.

[0075] The method further includes:

[0076] An entrance detector is provided at the exit channel of the cigarette packer to detect the moment when the cigarette enters.

[0077] A push rod in-place detector is provided to detect whether the push rod for pushing the beauty device has reached the set position.

[0078] A cigarette in-place detector is provided at the cigarette beauty station to detect whether the cigarette has reached the beauty station; a pressing in-place detector is provided to detect whether the ironing plate has been pressed in place.

[0079] An exit cigarette detector is provided at the cigarette ejection channel to detect the moment when the cigarette is ejected.

[0080] In practical applications, as Figure 2 shown, an entrance cigarette detector 11 is used to detect the timing when the cigarette enters the entrance of the beauty device and waits to be beautified. A cigarette in-place detector 12 is used to detect the timing when the cigarette enters the beauty station from the waiting area at the device entrance. A pressing in-place detector 13 is used to detect the timing when the single-time beautification of the cigarette at the beauty station ends. An exit cigarette detector 14 is used to detect the timing when the cigarette finishes beautification and enters the cigarette output conveyor belt. A push rod in-place detector 10 is used to detect the timing when the beautification action starts at the beauty station.

[0081] When a cigarette carton enters the entrance of the beautifier device from the exit channel of the packing machine, the entrance cigarette carton detector 11 detects the entry of the cigarette carton and prepares to compress and beautify the cigarette carton. When the cigarette carton push rod 9 starts the next action, the cigarette carton is pushed into the beautifying station. The push rod action detector 10 detects the push rod, indicating that the push rod action has ended. The cigarette carton pauses at the beautifying station. The cigarette carton in-place detector 12 here detects the cigarette carton, and the beautifying iron starts to press down. When the pressing down ends, the pressing down action detector 13 detects the pressing plate, indicating that the pressing plate action is in place. Next, the pressing plate rises, and the cigarette carton is pushed out of the beautifier device. When it is completely pushed out, the exit cigarette carton detector 14 can detect the cigarette carton signal, indicating that the beautifying work of this cigarette carton is over and the cigarette carton is successfully pushed out. Through the five sensors, the motion state monitoring system realizes the monitoring of the core actions in the working process of the beautifier device and provides state information that can be relied on for the subsequent action flexibility.

[0082] The method further includes:

[0083] Obtain the signal trigger moment of the entrance detector to obtain the cigarette carton pushing-in time;

[0084] Obtain the time difference between the signal triggers of the cigarette carton in-place detector and the pressing-down in-place detector as the pressing-down time;

[0085] Obtain the signal trigger moment of the exit cigarette carton detector to obtain the cigarette carton pushing-out time;

[0086] During the beautifying of a cigarette carton at a station, judge the action flexibility of the cigarette carton beautifying device according to the cigarette carton pushing-in time, the pressing-down time of the iron device, and the cigarette carton pushing-out time.

[0087] The method further includes:

[0088] Compare the cigarette carton pushing-in time, the pressing-down time of the iron device, and the cigarette carton pushing-out time with preset values to judge the action flexibility of the cigarette carton beautifying device according to the deviation value.

[0089] In practical applications, calculate the actual motion time of each action, then compare the actual motion time with the ideal motion time, judge whether there are joints with inflexible actions, and give scientific maintenance suggestions. Different action times include: the time for the cigarette carton to be pushed into the beautifier, the time for the iron to be pressed tightly, the time for the iron to be relaxed, and the time for the cigarette carton to be pushed out of the beautifier. Through these actions, monitor the working state of the beautifier device, and compare the actual action time with the theoretical action time to judge whether each joint is in an ideal state in the current state.

[0090] It can be seen that the present invention provides a monitoring method for a strip cigarette beauty device, which performs on-line temperature detection on the irons on each side of the beauty device, records the degree of temperature fluctuation and the frequency of abnormal states, and forms a temperature monitoring record form to evaluate the reliability of the irons on each side. This solves the problem that the existing strip cigarette transparent paper shaping using a beauty device lacks status monitoring, which is likely to cause unstable operation of the equipment and untimely fault maintenance, and can improve the reliability and operation efficiency of the strip cigarette beauty device.

The above are only the preferred embodiments of the present invention, but the present invention is not limited to the scope of implementation shown in the drawings.
