[0015] The present invention is not limited by the following embodiments, and specific implementation methods can be determined according to the technical solution of the present invention and actual conditions.

[0016] The present invention is further described below in conjunction with the embodiments and drawings:

[0017] Example 1: Figure 1 As shown, a conveying device for automatically conveying materials in a factory includes a controller, a transmission device and a coal conveying module; the coal conveying module includes a coal feeder, a coal crusher, a coal screener and a coal plow; the transmission device includes a sensor module and a transmission module, the transmission module includes a No. 1 belt, a No. 2 belt and a No. 3 belt, and the sensor module, the coal feeder, the coal crusher, the coal screener, the coal plow, the No. 1 belt, the No. 2 belt and the No. 3 belt are all connected to the controller.

[0018] During operation, after the coal is transported into the factory, it is first stored in the coal yard, and then sent into the coal hopper through some large mechanical equipment, such as grab buckets, and then transported to the coal bunker by belts. Specifically, the controller controls the coal feeder to start and run. After the coal feeder runs for a delay of 6S (the response time set in the controller), the controller controls the No. 1 belt to start; after the No. 1 belt runs for a delay of 6S, the controller controls the coal screener to start and screen the coal to remove impurities in the coal. After the coal screener runs for a delay of 6S, the controller controls the No. 2 belt to start. After the No. 2 belt runs for a delay of 6S, the controller controls the coal crusher to start and crush the coal into small coal blocks, which are then crushed and ground for the second time. After the coal crusher runs for a delay of 6S, the controller controls the No. 3 belt to start. After the No. 3 belt runs for a delay of 6S, the controller controls the coal plow to start and send the coal into the coal bunker, and then the belt under the coal bunker sends the material into the kiln for combustion.

[0019] like Figure 1 As shown, it also includes a display light module, which includes a coal feeder light, a coal crusher light, a coal screener light, a coal plow light, a No. 1 belt light, a No. 2 belt light, a No. 3 belt light and a fault indicator light. The coal feeder light, the coal crusher light, the coal screener light, the coal plow light, the No. 1 belt light, the No. 2 belt light, the No. 3 belt light and the fault indicator light are all connected to the controller.

[0020] During operation, the coal feeder starts and runs, and the corresponding coal feeder light comes on; belt No. 1 starts and runs, and the corresponding belt No. 1 lights up; the coal screener starts and runs, and the corresponding coal screener light comes on; belt No. 2 starts and runs, and the corresponding belt No. 2 light comes on; the coal crusher starts and runs, and the corresponding coal crusher light comes on; belt No. 3 starts and runs, and the corresponding belt No. 3 light comes on; the coal plow starts and the corresponding coal plow light comes on; thus, by setting the corresponding indicator lights, it is used to display the operating status of each equipment; by setting the fault indicator light, the fault indicator light comes on, indicating that the device is in a fault state, which is convenient for the staff to check intuitively.

[0021] like Figure 1 , 2 As shown, it also includes a button module, which includes an automatic sequential start button, an automatic sequential stop button, a total emergency stop button, a coal feeder stop button, a coal crusher stop button, a coal screener stop button, a coal plow stop button, No. 1 belt stop button, No. 2 belt stop button, No. 3 belt stop button, No. 1 belt fault button, No. 2 belt fault button, No. 3 belt fault button and a fault clearing and reset button, and the automatic sequential start button, the automatic sequential stop button, the total emergency stop button, the coal feeder stop button, the coal crusher stop button, the coal screener stop button, the coal plow stop button, No. 1 belt stop button, No. 2 belt stop button, No. 3 belt stop button, No. 1 belt fault button, No. 2 belt fault button, No. 3 belt fault button and a fault clearing and reset button are all connected to the controller.

[0022] The above-mentioned automatic sequence start button and automatic sequence stop button are used for starting and stopping the entire device respectively, and can be controlled manually or by a controller.

[0023] The above-mentioned coal feeder stop button, coal crusher stop button, coal screener stop button, coal plow stop button, No. 1 belt stop button, No. 2 belt stop button, and No. 3 belt stop button can all be manual emergency stop switches and can also be controlled by a controller. When the coal feeder and other equipment are damaged or the belt fails, the corresponding equipment can be stopped by pressing the corresponding stop button to avoid equipment failure.

[0024] The above-mentioned No. 1 belt fault button, No. 2 belt fault button, and No. 3 belt fault button are all controlled by the controller. When the controller determines that No. 1 belt, No. 2 belt or No. 3 belt has a fault, the controller controls the corresponding fault button to operate, causing the corresponding belt to stop running.

[0025] The above-mentioned general emergency stop button is connected to the main power supply and is used to cut off the main power supply when a major fault occurs in the device, so that all equipment stops running.

[0026] The above-mentioned fault clearing and reset button is used when a fault occurs and needs to be cleared. By pressing the fault clearing and reset button, the fault is cleared, and the process can be started in sequence after resetting.

[0027] like Figure 1 As shown, the sensing device includes multiple sensors and multiple deviation switches. The No. 1 belt, the No. 2 belt and the No. 3 belt are respectively provided with sensors and deviation switches, and all sensors and deviation switches are connected to the controller.

[0028] The above-mentioned sensor is an existing well-known technology. It uses a pulse frequency of 10Hz to detect the specific position and actual status of the operation of belts No. 1, No. 2 and No. 3, and is used to detect the operating status of the belts, whether they are broken, whether they are blocked and stopped, and whether the belts are too loose or collapsed. The pulse frequency of the sensor is set by the clock signal of the controller. If the pulse disappears and the sensor output signal is zero, it indicates a fault. The belt may be broken, blocked and stopped, too loose or collapsed. The controller then controls the corresponding belt to stop running, and at the same time controls all equipment running before the belt to stop running to avoid faults.

[0029] The above-mentioned deviation switch is an existing well-known technology. The deviation switch is used to detect whether the belt is deviated and send the detection status to the controller. The controller determines whether the corresponding belt is deviated based on the received detection status. If it is determined that the corresponding belt is deviated, the controller controls the belt to stop running, and at the same time controls all equipment running before the belt to stop running to avoid malfunctions.

[0030] like Figure 1 As shown, a resistive coal level sensor is also included, and the resistive coal level sensor is connected to the controller.

[0031] The above-mentioned resistive coal level sensor is an existing well-known technology. By installing the resistive coal level sensor in the coal bunker, the coal level in the coal bunker is detected. When the coal loading in the coal bunker exceeds the limit, the resistive coal level sensor outputs an over-limit signal to the controller, and the controller controls the automatic sequential stop button to be pressed (the automatic sequential stop button can also be pressed manually). From the coal feeder to the coal plow, they all stop after a delay of 6S, and the corresponding operation indicator lights are also extinguished accordingly.

[0032] Example 2: Figure 3 As shown, a transmission method of a conveying device for automatically conveying materials in a factory comprises the following steps:

[0033] Step S1, determining whether the coal feeder is faulty, and if so, stopping the coal feeder to clear the fault;

[0034] Step S2, if the response is no, start the No. 1 belt; determine whether the No. 1 belt is faulty, and if the response is yes, stop the No. 1 belt and the coal feeder to clear the fault;

[0035] Step S3, if the response is no, start the coal screening machine; determine whether the coal screening machine is faulty, if the response is yes, stop starting the coal screening machine and clear the fault;

[0036] Step S4, if the response is no, start the No. 2 belt; determine whether the No. 2 belt is faulty, if the response is yes, stop the No. 2 belt, the coal screener, the No. 1 belt and the coal feeder to clear the fault;

[0037] Step S5: if the response is no, then start the coal crusher; determine whether the coal crusher is faulty, if the response is yes, then stop starting the coal crusher and clear the fault;

[0038] Step S6, if the response is no, then start the No. 3 belt; determine whether the No. 3 belt is faulty, and if the response is yes, then stop the No. 3 belt, the coal crusher, the No. 2 belt, the coal screener, the No. 1 belt and the coal feeder to clear the fault;

[0039] Step S7, if the response is no, then start the coal plow; determine whether the coal plow is faulty, if the response is yes, then stop starting the coal plow and clear the fault;

[0040] Step S8: If the response is no, all devices are started up in sequence.

[0041] like Figure 3 As shown, in step S2, if the response is no, the No. 1 belt will be started after a delay of 6S; in step S3, if the response is no, the coal screener will be started after a delay of 6S; in step S4, if the response is no, the No. 2 belt will be started after a delay of 6S; in step S5, if the response is no, the coal crusher will be started after a delay of 6S; in step S6, if the response is no, the No. 3 belt will be started after a delay of 6S; in step S7, if the response is no, the coal plow will be started after a delay of 6S.

[0042] As needed, in step S2, if the response is no, the corresponding coal feeder light will turn on; in step S3, if the response is no, the corresponding No. 1 belt conveyor light will turn on; in step S4, if the response is no, the corresponding coal crusher light will turn on; in step S5, if the response is no, the corresponding No. 2 belt conveyor light will turn on; in step S6, if the response is no, the corresponding coal screener light will turn on; in step S7, if the response is no, the corresponding No. 3 belt light will turn on; in step S8, if the response is no, the corresponding coal plow light will turn on.

[0043] Example 3: Figure 4As shown, the controller may be an existing well-known S7-2000 CPU226PLC controller, wherein the coal feeder, coal crusher, No. 1 belt, coal screener, No. 2 belt, coal plow and No. 3 belt are respectively connected to the Q0.0, Q0.1, Q0.2, Q0.3, Q0.4, Q0.5 and Q0.6 terminals of the PLC controller output end; the coal feeder light, coal crusher light, coal screener light, coal plow light, No. 1 belt light, No. 2 belt light, No. 3 belt light and fault indicator light are respectively connected to the Q1.0, Q1.1, Q1.2, Q1.3, Q1.4, Q1.5, Q1.6 and Q1.7 terminals of the PLC controller output end; the automatic sequence start button, The automatic sequence stop button, the general emergency stop button, the coal feeder stop button, the No. 1 belt stop button, the coal crusher stop button, the No. 2 belt stop button, the coal screener stop button, the No. 3 belt stop button, the coal plow stop button, the No. 1 belt break fault button, the No. 2 belt jam or deviation fault button, the No. 3 belt too loose collapse fault button, and the fault clearing and reset button are respectively connected to the I0.0, I0.1, I0.2, I0.3, I0.4, I0.5, I0.6, I0.7, I1.0, I1.1, I1.2, I1.3, I1.4, and I1.5 terminals of the PLC controller input end.

[0044] The above method can be used to simulate faults, specifically:

[0045] If the No. 1 belt breaks and the belt pulse disappears, the No. 1 belt and all previous equipment will stop immediately, the fault indicator light will flash continuously at a pulse frequency of 2HZ, and the subsequent equipment will stop running after a delay of 6s;

[0046] If the No. 2 belt is blocked and stops rotating or deviates, the belt pulse disappears, the No. 2 belt and all the previous equipment stop immediately, the fault indicator light flashes, and the subsequent equipment stops running after a delay of 6 seconds;

[0047] If the No. 3 belt is too loose and collapses, the pulse signal disappears, the fault indicator light flashes, and all equipment must be stopped immediately;

[0048] If the above faults occur, you need to press the Clear Fault button after clearing the fault, and start the process in sequence after resetting.

[0049] In summary, the utility model controls the start and stop of various equipment in the coal transportation process by setting a controller, and has a high degree of automation; the controller determines whether the coal feeder, coal crusher, coal screen and coal plow are faulty in the coal transportation process. If a fault is determined, the corresponding faulty equipment is stopped and the fault is cleared in time; at the same time, the controller determines whether the No. 1 belt, the No. 2 belt and the No. 3 belt are broken, deviated, the coal drop pipe is blocked, too loose and collapsed, etc. If a fault is determined, the corresponding belt and all equipment that has been running before the belt are stopped, and the fault is checked and cleared in time to ensure accurate and efficient coal transportation, and avoid the problem of low working efficiency of the coal transportation system caused by manual opening of the belt conveyor to transport coal to the coal storage bin.
