[0002] In the tobacco industry, cigarette quality inspection is an important process, especially in the detection of moisture density distribution, which is of great significance to ensure the quality of cigarettes. When the existing cigarette moisture density distribution measuring instrument is used to detect cigarettes, it is usually necessary to take the cigarettes out of the hopper one by one and send them to the detection area. However, the traditional hopper design has problems such as unstable cigarette removal and easy damage to cigarettes, which affects the accuracy and efficiency of detection. In addition, the motor drive system inside the hopper mostly relies on a dedicated motor driver, which not only increases the cost of the equipment, but also limits the flexibility and adaptability of the equipment. Therefore, it is of great significance to develop a control system that can efficiently and stably remove cigarettes from the hopper and is easy to modify and upgrade, which is of great significance to improving the efficiency of cigarette detection and the efficiency of equipment development and transformation.

[0037] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments:

[0038] like Figure 1 and Figure 2As shown, the hopper cigarette taking control device for the cigarette moisture density distribution measuring instrument includes a controller 1, a 24V DC power supply 2, a DC motor 3, a solid-state relay 4, an electromagnetic relay 5, a cigarette separation component 6, a cigarette to be tested 7, a cigarette storage component 8, a current sensor 9 and an AD sampling module 10; the controller 1, the solid-state relay 4, and the electromagnetic relay 5 form a loop, the 24V DC power supply 2 is connected to the solid-state relay 4 and the electromagnetic relay 5 through lines, and the electromagnetic relay 5, the current sensor 9, and the DC motor 3 form a loop; the DC motor 3 is connected to the AD sampling module 10 and the cigarette separation component 6 through lines, and the cigarette separation component 6 is connected to the cigarette storage component 8 through a fixed bracket; wherein,

[0039] The controller 1 is configured to be responsible for the control logic of the entire device, adjust the speed of the DC motor through PWM, and monitor the operating status of the DC motor 3;

[0040] A 24V DC power supply configured to power the entire device;

[0041] The DC motor 3 is configured to drive the cigarette separation component 6 to rotate and has a state detection function to prevent the cigarette to be tested from being squeezed and deformed during the cigarette removal process;

[0042] The solid-state relay 4 is configured to adjust the voltage applied to the DC motor 3 to achieve stepless speed regulation of the DC motor 3;

[0043] The electromagnetic relay 5 is configured to change the phase of the DC motor 3 when the DC motor 3 runs for a timeout or detects that the cigarette to be tested is successfully picked up, so as to ensure that the DC motor 3 runs correctly;

[0044] The cigarette separation component 6 is configured to achieve smooth separation of cigarettes, ensuring that only one cigarette enters the detection area at a time;

[0045] The cigarette storage component 8 is configured to store the cigarettes 7 to be tested, and supports batch measurement requirements;

[0046] The current sensor 9 and the AD sampling module 10 are configured to collect the working current of the DC motor 3 to obtain the operating status of the DC motor 3 .

[0047] The cigarette separation component 6 includes a feed roller with a cigarette taking slot, which is located at the bottom of the hopper; the DC motor 3 drives the feed roller to rotate to prevent the cigarettes to be tested from being squeezed and deformed during the cigarette taking process.

[0048] Motor status detection function: By designing conventional status detection algorithms or machine learning classification models (Support Vector Machine (SVM), Random Forest, Neural Network, etc.), different working status labels of the motor (normal operation, overload, stalled motor) are obtained.

[0049] How it works

[0050] The controller 1 uses PWM technology to adjust the output of the 24V DC power supply 2 and adjusts the working voltage of the DC motor by controlling the solid-state relay 4, thereby achieving speed regulation of the motor 3.

[0051] The operating current of the motor 3 is collected through the current sensor 9 and the AD sampling module 10, and the different working state labels of the motor (normal operation, overload, stall) are obtained by designing a conventional state detection algorithm or a machine learning classification model (support vector machine (SVM), random forest, neural network, etc.).

[0052] When the cigarette 7 to be tested is successfully picked up, the controller 1 will stop the motor for a period of time. At the same time, during the operation of the system, the operating current of the DC motor 3 is collected and combined with relevant algorithms to obtain the operating status of the DC motor 3 and perform corresponding processing.

[0053] If the DC motor 3 operates normally and the cigarette separation component 6 rotates in timeout, the upper computer will notify the operator of the empty hopper state; if the DC motor 3 is overloaded and the cigarette separation component 6 is stuck, the electromagnetic relay 5 will be controlled to change the rotation direction of the DC motor 3 so that the cigarette separation component 6 rotates in the opposite direction, thereby solving the problems of DC motor overload and hopper jam; if the DC motor is blocked, the controller 1 will stop the DC motor 3 and sound an alarm.

[0058] Step 3: Perform real-time sampling of the motor current, and use the collected current data to determine the state of the DC motor through a conventional state detection algorithm or a machine learning classification model;

[0059] Step 4: Determine whether the DC motor is stalled;

[0060] If the result of the judgment is that the motor is stalled, the controller's human-machine interface will alarm and display the motor overload, prompting the user to take appropriate measures;

[0061] Or if the result of the judgment is that there is no stall, go to step 5;

[0062] Step 5: Determine whether the DC motor is overloaded;

[0063] If: the judgment result is that overload occurs, the DC motor reverse control process is started;

[0064] Or if the judgment result is that there is no overload, execute step 6;

[0065] Step 6: Determine whether the DC motor running time exceeds the preset time;

[0066] If: the result of the judgment is that the running time of the DC motor exceeds the preset time, the controller's human-machine interface will alarm and display that the hopper is short of smoke, prompting the user to take corresponding measures;

[0067] Or if the result of the determination is that the running time of the DC motor does not exceed the preset time, then execute step 7;

[0068] Step 7: Determine whether the number of cigarettes to be taken has been reached;

[0069] If: the result of the judgment is that the number of cigarettes taken is reached, then the process ends;

[0070] Or if the result of the judgment is that the number of cigarettes to be taken is not reached, go to step 2 and continue the cigarette picking and testing process.
