Detailed Description
The present invention is described in terms of particular embodiments, other advantages and features of the invention will become apparent to those skilled in the art from the following disclosure, and it is to be understood that the described embodiments are merely exemplary of the invention and that it is not intended to limit the invention to the particular embodiments disclosed. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The method provided by the invention can quickly and effectively judge whether the tension roller slips or not based on the linear speed and the actual torque value of the tension roller, and can quickly and accurately judge whether the tension roller slips or not from a plurality of possible reasons when the tension fluctuates, thereby playing an important role in ensuring the stable operation of a unit and the yield of the unit.
In one embodiment, the method for determining a slip of a tension roller in a strip steel processing line according to the present invention, as shown in fig. 1, includes the steps of:
s1: and acquiring the tension state of each tension roller to monitor whether tension fluctuation occurs to any tension roller in the tension roller group. It should be understood that the tension state referred to herein refers to both a normal state in which the tension is not fluctuated and an abnormal state in which the tension is fluctuated.
S2: and if the tension fluctuation of any tension zone is judged, setting the tension roller of the tension zone as a target tension roller, wherein the target tension roller is the target roller for subsequent roller type determination and motion parameter value acquisition.
S3: acquiring the roller type of the target tension roller and the motion parameter value of the target tension roller; the method for acquiring the roller type of the target tension roller specifically comprises the following steps: acquiring a code corresponding to the target tension roller according to prestored data; and judging the target tension roller to be a master roller or a slave roller based on the codes. Acquiring a motion parameter value of a target tension roller, specifically comprising: and acquiring a linear speed set value, a linear speed actual value and an actual torque curve of the target tension roller. That is, in the determination process, it is first clarified that the number of rollers in the tension roller group in the control program is the master roller and the number of rollers is the slave roller, and this factor is set in the control program and is a parameter prestored in the system. And when the tension fluctuates, checking the linear speed set value, the linear speed actual value and the actual torque curve of the tension roller, and analyzing the curve.
S4: based on the roller type and the motion parameter value, it is determined whether the target tension roller is slipping.
Since the target tension roller may be a master roller or a slave roller, and the motion characteristics and principles of the master roller and the slave roller are different, a distinction needs to be made.
Specifically, the target tension roller is determined to be a main roller, and in the obtained motion parameter values, the actual linear speed is consistent with the set linear speed, and the actual torque of the motor is smaller than the set running torque, it is determined that the target tension roller slips.
And judging whether the target tension roller is a slave roller, and if the actual torque of the motor is smaller than the set running torque and the actual linear velocity is not equal to the set linear velocity in the obtained motion parameter values, judging whether the target tension roller slips or not by combining the positive and negative states of the torque of the master roller and the relationship between the speed of the target tension roller and the set speed value.
Further, the determining whether the target tension roller slips or not by combining the positive and negative states of the main roller torque and the relationship between the speed of the target tension roller and a speed set value specifically includes:
when the torque of the main roller is a positive value, the speed of the target tension roller is greater than a speed set value under the action of the additional torque, and the target tension roller is judged to slip;
and when the torque of the main roller is a negative value, the speed of the target tension roller is smaller than a speed set value under the action of the additional torque, and the target tension roller is judged to be slipped.
The following is a brief description of the working principle of the equipment and the specific implementation process of the method applied in the above method, taking the continuous production of the strip as an example.
In the continuous strip production line, the tension roller group comprises two rollers, three rollers, four rollers and the like according to the requirement of tension magnification as shown in figures 2-4. In the whole production line, one tension roller group is a speed reference roller and does not participate in tension adjustment; another set of tension rollers participates in adjusting the tension. When the outlet tension of the tension roller is greater than the inlet tension, the tension roller works in a power generation state; when the inlet tension is greater than the outlet tension, the tension roller group works in an electric state.
The single tension roller is controlled by double closed loop speed regulation, the outer loop is a speed loop ASR, and the inner loop is a current loop ACR. The tension roller motor is provided with an encoder for measuring the rotating speed of the motor and feeding the rotating speed back to the frequency converter, the frequency converter receives a speed set value from the PLC, compares the speed set value with a feedback value, inputs the speed set value into the speed controller, the speed controller is a PI controller, outputs the speed set value to the current controller, and finally outputs the speed set value to the motor.
For the tension roller group, in order to ensure that the force of a plurality of tension rollers in the roller group is uniform, the load balance is carried out between the tension rollers, the tension rollers are internally provided with a main roller and a slave roller, and the specific control method comprises the following steps: the integral quantity of the speed regulator of the main roller in the tension roller group is output to the slave roller in the same tension roller group, and the integral of the speed regulator of the slave roller is not enabled. Thus, when the main roller torque is excessive, the load of the main roller is shared by the sub roller.
The judgment of the slipping of the tension roller needs to refer to the set speed, the actual speed and the actual torque of the tension roller, and the main roller and the slave roller in the tension roller group need to be analyzed in a distinguishing way. When the main roller slips, the absolute value of the torque becomes smaller and approaches the idling torque, and the actual speed value is equal to the set speed value. The slave roll slips, the load becomes smaller and is close to the no-load torque, but the actual speed value of the slave roll is inversely unequal to the set speed value, because the load borne by the master roll is increased, the absolute torque value of the master roll becomes larger, the integral component of the master roll speed controller increases, the value added to the speed control output of the slave roll becomes larger, and if the master roll torque is a positive value, the speed of the slave roll is larger than the set speed value under the action of the added positive torque; if the torque of the master roll is negative at that time, the speed of the slave roll will be less than the speed set point under the action of the additional negative torque. According to this principle, the present invention proposes the above-described analysis method for determining the slip of the tension roller based on the set speed, the actual speed, and the actual value of the torque.
As described below with reference to the examples, a certain No. 3 tension roller group of a strip machine includes 2 tension rollers, and No. 1 roller of the tension roller group is a slave roller and No. 2 roller is a master roller. In fig. 5, curve a is the torque of roller No. 1, curve B is the torque of roller No. 2, curve a is the actual speed of roller No. 1, and curve B is the actual speed of roller No. 2. It can be seen that at 14:56 min 43 sec, the torque of the No. 1 roller is reduced from-20% to-5%, and the torque of the No. 2 roller is increased from-35% to-50%. At this time, the actual speed of the No. 1 roller is 0.637m/s which is much lower than the set speed of 0.667m/s, and the No. 1 roller is judged to have slippage at this time according to the No. 1 roller. At 14:56 min 48 s, the torque of the roller No. 2 is reduced from-50% to-15%, the actual speed of the roller No. 2 is equal to the set speed of 0.667m/s, and the roller No. 2 is judged to be the main roller according to the condition that the roller No. 2 also slips at the moment. After the two rollers are slipped, the actual value of the front tension of the tension roller set is far greater than the set value, the unit gives an alarm, and the unit is stopped at a reduced speed. As shown in fig. 7, the actual tension (curve C) is much greater than the set tension (curve D).
Therefore, according to the tension roller slip judging method based on the strip steel processing production line, the tension state of each tension roller is obtained, the tension fluctuation of any tension roller is judged, and the tension roller is set as the target tension roller; after the target tension roller is determined, the roller type of the target tension roller and the motion parameter value of the target tension roller are obtained, and whether the target tension roller slips or not is judged based on the roller type and the motion parameter value. By the method, when the tension roller generates tension fluctuation, two key indexes for judging the slippage of the tension roller in the tension roller group and the relationship between the two key indexes are clearly pointed out, so that whether the tension roller slips or not can be quickly and accurately judged out of a plurality of influence factors when the tension fluctuation occurs in the operation of a production line, and the method provides guarantee for quickly handling faults and ensuring the stable operation of a unit. The technical problem that whether tension fluctuation caused by slipping of the tension roller cannot be judged in the prior art is solved.
In addition to the above method, the present invention provides a tension roller slip determination apparatus based on a strip processing line, as shown in fig. 8, the apparatus comprising:

That is, in the determination process, it is first clarified that the number of rollers in the tension roller group in the control program is the master roller and the number of rollers is the slave roller, and this factor is set in the control program and is a parameter prestored in the system. And when the tension fluctuates, checking the linear speed set value, the linear speed actual value and the actual torque curve of the tension roller, and analyzing the curve.
A result determination unit 400 for determining whether the target tension roller has a slip based on the roller type and the motion parameter value.
Since the target tension roller may be a master roller or a slave roller, and the motion characteristics and principles of the master roller and the slave roller are different, a distinction needs to be made.
Specifically, the target tension roller parameter obtaining unit 300 is configured to determine that the target tension roller is a main roller, and in the obtained motion parameter values, if the actual linear velocity is consistent with the set linear velocity and the actual torque of the motor is smaller than the set operation torque, it is determined that the target tension roller slips. And judging whether the target tension roller is a slave roller, and if the actual torque of the motor is smaller than the set running torque and the actual linear velocity is not equal to the set linear velocity in the obtained motion parameter values, judging whether the target tension roller slips or not by combining the positive and negative states of the torque of the master roller and the relationship between the speed of the target tension roller and the set speed value.
Further, the result determination unit 400 is specifically configured to: when the torque of the main roller is a positive value, the speed of the target tension roller is greater than a speed set value under the action of the additional torque, and the target tension roller is judged to slip; and when the torque of the main roller is a negative value, the speed of the target tension roller is smaller than a speed set value under the action of the additional torque, and the target tension roller is judged to be slipped.
