Simulation Control Method of Coiler Unloading Car Lifting Position Encoder

Abstract

The invention belongs to the automatic control field of coil discharging of a hot continuous rolling recoiling machine. According to a recoiling machine coil unloading dolly lifting position coder simulation control method, marks are marked on a guide rail of a coil unloading dolly; after a recoiling machine coils band steel, an operator observes position marks on the coil unloading dolly on the guide rail and inputs the position marks into a computer if a fault of the coil uncoiling dolly lifting position coder occurs; the computer operates a simulation program and controls the coil unloading dolly to unload steel coils from a coiling block. The recoiling machine coil unloading dolly lifting position coder simulation control method solves the problem that faults of detection equipment cause coil unloading not to be conducted normally, reduces failure processing time, and avoids ambustion of hot coils on machines and electric equipment around the recoiling machine.

Description

technical field [0001] The invention belongs to the field of automatic control of coil unloading of hot continuous rolling coiler. Background technique [0002] After the coiler finishes coiling the steel strip, the coil unloading trolley must unload the steel coil from the reel in time to prepare for rolling the next piece of steel. If the lifting position encoder of the unloading trolley breaks down, the position signal of the trolley cannot be fed back to the computer normally, which will cause abnormal movement of the unloading trolley, and the steel coils on the reel cannot be unloaded normally, resulting in production stoppage, and five or six hundred If the hot roll stays on the reel for a long time, it will cause damage to mechanical and electrical equipment. If the position encoder has no spare parts to replace, it will cause a long-term production stoppage, which will directly affect the production efficiency.
