Abstract
The invention provides a recoiling machine EPC system deviation rectification control method which can achieve deviation rectification and side portion alignment and solve the problem of strip steel deviation rectification abnormality. In the recoiling process, three conditions are set, offset of strip steel is smaller than 50 mm, displacement of a recoiling machine is smaller than 50 mm, and a difference value between the offset of the strip steel and the displacement of the recoiling machine is smaller than 5 mm; treatment is carried out according to the different circumstances; under the circumstances that an outlet is in an unloading tension state and an EPC is in a manual state, four states are set, the EPC is in a remote mode, an EPC deviation rectification servo motor is located at a stop position, the EPC deviation rectification servo motor is located at a limit position for fault reporting, and the EPC deviation rectification servo motor acts; two kinds of action are carried out, a main line PLC does not carry out treatment, or a main line PLC reads servo system faults to give an alarm to an operator; the abnormal situation is read through the main line PLC, a command is issued again to enable the EPC deviation rectification motor to return to the stop position, and an alarm is given to the operator; and treatment is carried out according to the different circumstances.
Description
Technical field
The present invention relates to a kind of coiling machine EPC system correction control method.
Background technology
Coiling machine is the mill equipment that hot rolling or cold rolling steel are coiled into drum, and EPC system is used for product pair
Side, such as Chinese patent of Application No. 201420340415.9.The problem that existing equipment is present is mainly EPC in itself without self-inspection
Function, is sometimes in operation under abnormal condition, and during detection strip data exception, EPC system can not only reach correction mesh
, occur serious volume on the contrary partially, while when occurring abnormal, EPC system does not know how treatment, it is impossible to automatically resets, causes
Partially, steel edge portion produces spark to band coil of strip with push pedal friction when serious, and product quality, the outward appearance of product are all subject to serious shadow
Ring.
The content of the invention
It is an object of the invention to overcome above shortcomings in the prior art, and provide a kind of reasonable in design batching
Machine EPC system correction control method, can process correction, edge alignment, the problem of strip steel deviation exception.
The present invention the used technical scheme that solves the above problems is：A kind of coiling machine EPC system correction control method, its
It is characterised by：Control process is as follows：
First, in coiling process, following three condition is set：
Condition 11：The side-play amount of strip is less than 50mm；
Condition 12：The displacement of coiling machine is less than 50mm；
Condition 13：Difference between strip side-play amount and coiling machine displacement is less than 5mm；
Testing conditions 11, condition 12, condition 13 successively, when these three conditions are satisfied by, it is believed that equipment is normal；Work as three above
When condition either condition is unsatisfactory for, it is believed that unit exception, in the alarm partially of outlet section report volume and not work disposal；
2nd, unload in outlet, in the case that EPC is in manual mode, set following four states and two actions：
State 21：EPC is in remote mode；
State 22：EPC deviation-rectifying servo motors are in stop position；
State 23：EPC deviation-rectifying servo motors limit position report failure；
State 24：EPC deviation-rectifying servo motor actions；
Action 21：Main line PLC does not deal with or main line PLC reads servo-drive system failure, is alarmed to operating personnel；
Action 22：Abnormal conditions are read by main line PLC, issuing an order again makes EPC deviation-rectifying servo motors return to stop position, and
Alarmed to operating personnel；
When state 21 meets, state 22 is carried out, when state 21 is unsatisfactory for, outlet section start and stop are not influenceed by EPC；
When state 22 meets, action 21 is carried out, when state 22 is unsatisfactory for, carry out state 23；
When state 23 meets, action 21 is carried out, when state 23 is unsatisfactory for, carry out state 24；
When state 24 meets, action 21 is carried out, when state 23 is unsatisfactory for, carry out action 22.
The present invention after condition 13 meets, repeats when condition 11, condition 12, condition 13 are satisfied by since condition 11
Row detection.
After the completion of present invention action 22, repeat state 21.
The present invention compared with prior art, with advantages below and effect：By the side-play amount of recording control system strip,
Whether the displacement of coiling machine and the state of EPC deviation-rectifying servo motors are abnormal to analyze deviation-rectifying system, then with according to exception
Situation, external system is instructed to EPC, controller is made corresponding treatment, EPC is returned to normal condition, while in operation
Alarm is given on the computer of personnel, the phenomenon of strip running deviation when coil of strip finishes up is eliminated, has prevented to be made because of EPC non-normal workings
Into the quality problems such as staggered floor, very big improves product quality.
Brief description of the drawings
Fig. 1 is control flow chart of the invention.
Specific embodiment
The present invention is described in further detail below and by embodiment, and following examples are explanation of the invention
And the invention is not limited in following examples.
Referring to Fig. 1, a kind of coiling machine EPC system correction control method, control process is as follows：
First, in coiling process, according to the data analysis of system operation, the side-play amount of strip and the displacement of coiling machine be constantly with
The characteristics of track is consistent, and the data most time of strip skew is within 50mm, therefore setting following three condition：
Condition 11：The side-play amount of strip is less than 50mm；
Condition 12：The displacement of coiling machine is less than 50mm；
Condition 13：Difference between strip side-play amount and coiling machine displacement is less than 5mm；
Testing conditions 11, condition 12, condition 13 successively, when these three conditions are satisfied by, it is believed that equipment is normal, and condition 13 is full
After foot, detection is repeated since condition 11；When three above condition either condition is unsatisfactory for, it is believed that unit exception, prison
These data are controlled to realize rolling up alarm and not work disposal partially in outlet section report by the means of program.
2nd, EPC deviation-rectifying servos motor, due to the faulty operation of producers, can make EPC deviation-rectifying servo motors in production
Fail to be on correct position, cause equipment to fail follow procedure and preset step work, lose the function of correction.Therefore exist
In the case that outlet is unloaded, EPC is in manual mode, following four states and two actions are set：
State 21：EPC is in remote mode；
State 22：EPC deviation-rectifying servo motors are in stop position；
State 23：EPC deviation-rectifying servo motors limit position report failure；
