The switch signals of the belt loading conveyor include temperature stacking, steel wire rope (consisting of steel wire, rope core and grease) locking, material level, smoke, main motor return, etc., which can be divided into no potential switch and potential switch. The effective combination of man and machine in the assembly line fully reflects the flexibility of the equipment. It organically combines the conveying system, the accompanying fixture, the online special machine, and the testing equipment to meet the assembly requirements of a variety of products. For the potential switch, since the switch input of the PLC requires a standard reference voltage of DC24V, it is necessary to convert the non-standard voltage through the amplifier circuit into a standard reference voltage that can be recognized by the PLC. The frequency response signal of the conveying equipment is that the speed sensor outputs a square wave signal with a peak value of 5V to the high-speed counting port of the PLC, so as to realize the detection of the running speed of the belt conveyor. Realize the protection of slipping and broken belt. The corresponding relationship between the frequency signal and the belt speed is: factory u003d 120V, where the factory is the output frequency value, the unit is HZ; the belt speed unit is m/s. The speed control of the belt conveyor by the system is as follows: After the belt conveyor is running normally. The chain conveyor
is a transmission device that uses standard chain plates as the bearing surface and is driven by a motor reducer. The chain conveyor is composed of a power unit (motor), a drive shaft, a roller, a tensioning device, a sprocket, a chain, a bearing, a lubricant, a chain plate, etc. The dryer mesh belt is a method that uses static friction. Friction-driven machinery that transports materials in a continuous manner. Using it, the material can be formed on a certain conveying line from the initial feeding point to the final unloading point to form a material conveying process. The programmable controller detects the speed of the belt loading conveyor in real time through a speed sensor (transducer) When the detected speed V70%VN is compared with the rated speed, the speed is considered normal; when 30%VN is ≤70% and lasts for several seconds, it is considered that a slip fault has occurred. When 0 ≤ 30%, for several seconds, a broken belt fault will occur, and the corresponding operation will be performed. belt technology is finally released. By detecting the three-phase main current, the current transformer detects the three-phase AC current of the main motor, converts it into an AC signal of 0 to 5A, and transmits it through power (referring to how much work the object does in a unit of time) The machine is optically coupled and isolated. The chain feeder is an auxiliary equipment in the mechanized storage and transportation system of lime production enterprises. Its main function is to continuously and uniformly feed processed or unprocessed materials from a certain equipment (hoppers, storage bins, etc.) The effective combination of people and machines in the assembly line of the material feeding equipment or transportation machinery fully reflects the flexibility of the equipment. It organically combines the conveying system, the accompanying fixture, the online special machine, and the testing equipment to meet the assembly requirements of a variety of products. . It is converted into a 0 to 5V DC signal and sent to the analog transmission module of the PLC. The 0~5V voltage signal has a strict linear relationship with the 0~5A current signal, which can reflect whether the three-phase current of the main motor is overloaded, power-off, or short-circuited (the current does not pass through the electrical appliance, and is directly connected to the two poles of the power supply). After conversion and isolation, the 0~5V voltage signal is sent to the PLC analog input module, and the CPU performs corresponding operations to achieve overload, phase failure and short circuit protection. Short circuit protection: When any one phase current of the three-phase working current of the main circuit is greater than 8 times the rated current, it is regarded as a short circuit. Split-phase protection: When the difference between any two-phase current of the three-phase working current of the main circuit is 0.6 times, and the duration exceeds 120s, the phase-failure protection can be activated. The upper computer of the control system combines the industrial computer IPC610 and the configuration software Kingview, connects the Siemens PLC2O to the RS232 serial port of the computer through a PCI cable, and establishes an MPI network for communication. The man-machine interface designed with configuration software has clear images, dynamically displays the operating status of equipment and the status of each execution sensor, detects parameters in real time, and queries historical data. It can also display the fault location and fault type when the equipment fails. At the same time, at the work site, the console will also have sound and light alarms and voice alarms, prompting the operator to do the corresponding treatment in time according to the situation.
