[0002] The belt conveyor is a motor and a reducer that drive the active roller to connect the tail roller and the upper and lower rollers of the frame to transmit the material through the friction of the conveyor belt to realize the transmission of the material. The belt conveyor currently used in the silk-making workshop of the tobacco factory is mainly used in the silk-making and re-baking lines of the cigarette factory. It is used in conjunction with the metering belt or the electronic belt scale to form a constant flow control system to control the flow of various materials in production. The belt conveyor system used in the factory needs to convey materials continuously, efficiently and at a large angle. In actual production, the materials on the belt conveyor often block the discharge port due to the moisture content and material characteristics of the materials. If the operator cannot find the blockage at the discharge port in time, the material conveying time will be greatly extended, resulting in zero flow on the electronic scale, unqualified processing parameters and quality indicators, and seriously affecting the continuity and stability of production. At the same time, when the blockage occurs, the belt is still running, which can easily damage the belt and equipment, affect the completion of production tasks, and cause bottlenecks in production. Therefore, it is of great significance to monitor and control the anti-blocking of the tobacco material conveying of the belt conveyor. Summary of the invention

[0027] In order to enable persons skilled in the art to better understand the solutions of the embodiments of the present invention, the embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings and implementation modes.

[0028] In view of the problem that the current belt conveyor for tobacco material transportation has the problem of untimely monitoring, which easily causes unstable tobacco production quality and reduced production efficiency, the present invention provides an anti-blocking monitoring system for belt conveyor tobacco material transportation, which solves the problem that the existing belt conveyor for tobacco material transportation has the problem of untimely monitoring, which easily causes unstable tobacco production quality and reduced production efficiency, can improve the continuity and stability of production, and reduce the maintenance cost of equipment.

[0029] like Figure 1 and Figure 2As shown, a blocking prevention monitoring system for tobacco material conveying on a belt conveyor comprises: a first photoelectric sensor 1, a second photoelectric sensor 2, a third photoelectric sensor 3, an alarm device and a controller. The first photoelectric sensor 1, the second photoelectric sensor 2 and the third photoelectric sensor 3 are correspondingly arranged on both sides of the material drop opening of the belt conveyor from high to low to perform layered detection of the accumulation thickness of the material in the material drop opening. The controller is respectively connected to the alarm device, the first photoelectric sensor, the second photoelectric sensor and the third photoelectric sensor signals, and judges according to the material accumulation thickness detected by the first photoelectric sensor, the second photoelectric sensor and / or the third photoelectric sensor, and controls the alarm device to give a blocking alarm when the material accumulation thickness is greater than the set threshold for blocking.

[0030] Specifically, the first photoelectric sensor is arranged at the first position of the belt conveyor blanking port, the second photoelectric sensor is arranged at the second position of the belt conveyor blanking port, and the third photoelectric sensor is arranged at the third position of the belt conveyor blanking port, wherein the first position, the second position and the third position are arranged in order from high to low. In one embodiment, the first position is a high-level alarm position for blocking, the second position is a normal position for materials, and the third position is a low-level alarm position for materials. When the material accumulation thickness is between the first position and the second position, the controller determines that the material accumulation is in a state of slight stagnation; when the material accumulation thickness is between the second position and the third position, the controller determines that the material accumulation is in a state of soft micro-lack of material. When the material accumulation thickness is less than the first position, the controller determines that the material accumulation is in a state of lack of material, and the speed of conveying materials by the belt conveyor is too slow. When the material accumulation thickness is greater than the third position, the controller determines that the material accumulation is in a state of blocking. If the blocking setting threshold is the same as the third position, the controller determines that blocking occurs when the material accumulation thickness is greater than the third position, and controls the alarm device to alarm to remind the operator to deal with the blocking. The system can solve the problem of untimely monitoring of blockage in the existing belt conveyor for tobacco material transportation, which can easily cause unstable tobacco production quality and reduced production efficiency. It can improve the continuity and stability of production and reduce the maintenance cost of equipment. At the same time, it can also monitor flow fluctuations and reduce water loss, and has a supervisory and control effect on process indicators. On the one hand, it avoids the problem of manual participation in subsequent processing and reduces labor intensity. On the other hand, it avoids the problems of material crushing, recycling and consumption due to blockage.

[0031] The system also includes: a visual acquisition device; the visual acquisition device is arranged at the outlet of the belt conveyor's material delivery port, and is used to perform video acquisition on the material delivery at the material delivery port; the controller is connected to the visual acquisition device by signal, and determines whether the material delivery is normal based on the material delivery image at the material delivery port acquired by the visual acquisition device, and controls the alarm device to sound an alarm when the material delivery is abnormal.

[0032] Specifically, the visual acquisition device can identify the material flow, material area and material movement direction based on the material conveying image of the drop port, and then determine whether the material conveying is normal. If it is abnormal, an alarm will be issued to remind the operator.

[0033] Furthermore, the visual acquisition device includes: a camera and an image recognition processor; the camera is signal-connected to the image recognition processor, and the image recognition processor is signal-connected to the controller. The image recognition processor identifies the movement status of the material on the conveyor belt based on the material conveying image acquired by the camera to determine whether the material conveying is normal.

[0034] The system also includes: a display; the display is respectively connected to the visual acquisition device and the controller signal, the display is provided with a human-computer interaction operation interface, and the operator queries the material conveying image of the blanking port in real time through the human-computer interaction operation interface.

[0035] The system also includes: a mobile communication module and a mobile terminal; the controller is connected to the mobile communication module by signal, and when material blockage occurs, the controller pushes alarm information to the mobile terminal corresponding to the operator through the mobile communication module.

[0036] Furthermore, the mobile terminal includes at least any one of the following: a smart phone, a smart wearable device, a tablet computer and an IPAD.

[0037] Furthermore, the first photoelectric sensor, the second photoelectric sensor and the third photoelectric sensor are infrared photoelectric tubes.

[0038] Furthermore, the alarm device includes at least any one of the following: an indicator light, a buzzer, and an audible and visual alarm.

[0039] Furthermore, the controller is a PLC programmable controller or a microprocessor.

[0040] The system also includes: a stop button; the controller is connected to the stop button signal, and the controller controls the alarm device to stop alarming when the stop button is pressed.

[0041] In actual applications, a photoelectric sensor for detecting the material layer thickness is installed at the blanking port of the belt conveyor. The material layer thickness data is detected by the photoelectric sensor and the data is fed back to the controller. The controller is preset with a database, which stores the data range of the material layer thickness of the belt conveyor currently in use. The data detected by the material layer thickness is compared with the material layer thickness limit value in the database. If the detected data is within the range, there is no material blockage. If the detected value exceeds the maximum range value, the controller determines that a material blockage has occurred. When it is determined to be a material blockage, the storage cabinet of the front-end process equipment and the belt conveyor immediately stop running, and the back-end equipment continues to run. When the material layer thickness data detected by the detection switch is within the value range, it is determined that the material blockage has been resolved, and the front-end equipment stops running for 3 seconds, thereby achieving precise control and preventing the occurrence of material blockage at the blanking port of the belt conveyor.

[0042] It can be seen that the present invention provides an anti-blocking monitoring system for belt conveyor tobacco material transportation, which adopts a first photoelectric sensor, a second photoelectric sensor and a third photoelectric sensor to be correspondingly arranged from high to low on both sides of the belt conveyor's drop port to perform layered detection on the material accumulation thickness in the drop port. When the material accumulation thickness is greater than the blockage set threshold, the controller controls the alarm device to issue a blockage alarm, thereby solving the problem of untimely blockage monitoring in existing belt conveyors for tobacco material transportation, which easily causes unstable tobacco production quality and reduced production efficiency, and can improve the continuity and stability of production and reduce the maintenance cost of equipment.
