The method comprises the steps of obtaining failure information of the coiler, wherein the step of obtaining the failure information of the coiler comprises obtaining at least one of electric failure information of the pinch roll on the coiler, hydraulic failure information of the pinch roll on the coiler, mechanical failure information of the pinch roll on the coiler and transmission failure information of the pinch roll.
Specifically, the production line has at least two recoiling machines, a first recoiling machine and a second recoiling machine, in the production process. When the pinch roll on the coiling machine has electric, hydraulic and mechanical faults and the transmission fault of the upper pinch roll, the first coiling machine does not have production conditions, and the second coiling machine cannot normally coil strip steel without the production conditions due to the fact that the upper pinch roll is located in a steel passing channel of the second coiling machine, and steel piling in a coiling area can be caused.
Step S120: and sending out a corresponding operation instruction according to the fault information so as to perform corresponding operation on the coiling machine. The method specifically comprises the step of sending a BYPASS command to a coiler pinch roll, wherein the step of sending the BYPASS command to the coiler pinch roll is the step of sending the BYPASS command to the coiler pinch roll by pressing a BYPASS button, and the BYPASS button is an independent operation button on a coiling human-computer interface operation picture.
Specifically, when the operator finds that the upper pinch roller is malfunctioning and does not have the production condition, the operator immediately presses a BYPASS button on an operation screen of a winding HMI (human machine interface), and deactivates the pinch roller 3.
Meanwhile, when the recoiling machines are correspondingly operated, if the last recoiling machine is not provided with the BYPASS function button, the last recoiling machine is stopped or idled by the current recoiling machine.
Step S130: and controlling the pinch roll of the recoiling machine to stop using based on the corresponding operation. Specifically, the upper roll of the pinch roll is controlled to rise to the highest position, the upper roll of the pinch roll stops rotating, and the valve of the current coiler descends to the lower position.
Specifically, the pinch roll 3 is stopped by pressing a BYPASS button, meanwhile, the first coiler on the front frame is stopped or emptied, a subsequent second coiler of the first coiler is used for coiling the strip steel, the PLC controls a first valve of the first coiler to be at a descending position, the head of the strip steel 7 can smoothly pass through an upper plate channel of the first coiler, and the first valve cannot act through manual intervention so as to avoid misoperation; the PLC controls the upper pinch roll to ascend to the maximum position and stop rotating so as to deal with the faults of the upper pinch roll in the aspects of electrical, hydraulic and transmission, at the moment, the second coiling machine can have production conditions to coil the strip steel 7, and the faults of the upper pinch roll are processed subsequently. In this embodiment, when the last reel winder fails and needs to be stopped, the last reel winder can be stopped, and therefore, the last reel winder does not need to be provided with the BYPASS function button.
