1) in, only when roll change detection unit detects that working roll is in the signal of traversing roll change position, just allow spindle holder device
It closes and roller of starting to work takes out roller action.
4. a kind of roll change sequence control method of working roll roll shifting milling train according to claim 1, which is characterized in that step
2) in, upper and lower working roll roll shifting to working position holding function module for realizing dress roller sequential control signal send out, sequentially-operating
It executes and roll shifting to working position feedback function；First determine whether that whether roll shifting to working position, is intermediate calender rolls, sends out working roll roll shifting
To working position actuating signal, roll change data will be reached by roll change logic control output unit under actuating signal send communication list
Member is finally completed by working roll roll shifting control execution unit；The working roll that will be detected by upper and lower work roll changing detection unit
Roll shifting feeds back to roll change to working position status signal via working roll roll shifting control feedback unit, roll change data receiver communication unit
Logic control input unit.
5. a kind of roll change sequence control method of working roll roll shifting milling train according to claim 1, which is characterized in that step
2) in, only when upper and lower working roll spindle alignment locking position detection unit detects that working roll locks signal, just allow spindle
Clamping device opening can continue the calibration of next step roll line.
6. a kind of roll change sequence control method of working roll roll shifting milling train according to claim 1, which is characterized in that step
3) it in, after roll change sequence control unit and man-machine interface communication, to be led by the WINCC application programs where man-machine interface
In the stations OS specified under entering to the paths control environment SEVER of roll changing system, and roll change sequential control is carried out in compilation process
On the basis of the VIS simulation of function, then the man-machine picture datas of the HMI of roll change sequential control are updated.
7. a kind of roll change sequence control method of working roll roll shifting milling train according to claim 2, which is characterized in that described
Working roll roll shifting control execution unit is by roll shifting mechanical equipment, hydraulic cylinder, servo valve, solenoid directional control valve and pressure sensor group
At each working roll is by 2 Driven by Hydraulic Cylinder, the same servo valve control of 2 hydraulic cylinders of each working roll.
