In order to solve the technical problems, the general idea of the embodiment of the application is as follows:

Under the better condition, the method can even avoid the band steel from being scratched, and further improves the yield, the quality and the yield.

In order to better understand the technical solution, the technical solution will be described in detail with reference to the drawings and the specific embodiments.

First, it is stated that the term "and/or" appearing herein is merely one type of associative relationship that describes an associated object, meaning that three types of relationships may exist, e.g., a and/or B may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.

After the strip steel is subjected to cold rolling operation, the strip steel can shake up and down due to tension fluctuation of a production line, and when the shaking amplitude of the strip steel is large, the lower surface of the strip steel can scratch other steel structures to scratch the strip steel. The scratch of the strip steel can seriously affect the product quality and the yield.

In order to solve the above technical problem, the present embodiment provides a strip steel shaking elimination apparatus as shown in fig. 1, which includes a strip steel shaking detection assembly, a controller and a tension control adjustment device.

The band steel shaking detection assembly is connected with the controller and used for detecting the target shaking amplitude of the band steel in the target direction and sending the target shaking amplitude to the controller;

the controller is connected with the tension control adjusting equipment and used for receiving a target shaking amplitude started by the strip steel shaking detection assembly, determining a target tension parameter of the strip steel according to the target shaking amplitude and sending the target tension parameter to the tension control adjusting equipment;

and the tension control and adjustment equipment is used for receiving the target tension parameters and adjusting the tension of the strip steel according to the target tension parameters.

The strip steel shaking detection assembly is arranged near a strip steel production line and is used for detecting the target shaking amplitude of the strip steel in the target direction. Generally, the strip is horizontally transported and vertically shaken. Therefore, the target direction can be set to the vertical direction. Of course, when the strip is not horizontally disposed, the target direction is perpendicular to the plane of the strip. Therefore, the target direction can be determined according to the setting state of the strip production line.

The strip steel shake detection assembly comprises a support, a strip steel amplitude detection sensor and a base. As shown in fig. 2, the base is disposed on the ground or other fixed object; one end of the bracket is fixed on the base, so that the bracket is suspended at one side (also can be an upper side, a left side, a right side or a lower side, and the specific direction is related to the type of the strip steel amplitude detection sensor used, and the detailed description is further described later) of the strip steel. The strip steel amplitude detection sensor is arranged on the support and connected with the controller, and is used for detecting the target shaking amplitude of the strip steel in the target direction and sending the target shaking amplitude to the controller.

The bracket supports the strip steel amplitude detection sensor at one side of the strip steel, so that the strip steel amplitude detection sensor can detect the target shaking amplitude of the strip steel.

The strip steel amplitude detection sensor can be an optical fiber sensor, an infrared detection sensor and the like.

An optical fiber sensor is a sensor that converts the state of an object to be measured into a measurable optical signal. The optical fiber sensor has the working principle that light beams incident from a light source are sent into a modulator through an optical fiber, the light beams interact with external measured parameters in the modulator, so that optical properties of the light, such as intensity, wavelength, frequency, phase, polarization state and the like, are changed to form modulated light signals, and the modulated light signals are sent into a photoelectric device through the optical fiber and then are demodulated to obtain the measured parameters.

In the embodiment, the optical fiber sensor irradiates a light beam on the surface of the strip steel, the light beam returns to the optical fiber sensor through the surface of the strip steel, and the height change of the strip steel in the target direction is determined through the change of the light beam. Therefore, when the strip amplitude detection sensor in the present embodiment is an optical fiber sensor, the optical fiber sensor needs to be disposed on the upper side or the lower side of the strip. Fig. 2 is a schematic view of the optical fiber sensor being disposed on the upper side of the strip steel through a bracket.

The infrared detection sensor is a pair of devices, one side of which is an infrared transmitter and the other side is an infrared receiver. The infrared transmitters and the infrared receivers are arranged on the left side and the right side of the strip steel (the left side and the right side refer to the left side and the right side of a strip steel production line), and the target shaking amplitude of the strip steel can be determined by detecting the amplitude range of the blocked infrared rays. Therefore, when the strip amplitude detection sensors in this embodiment are infrared detection sensors, the infrared detection sensors need to be disposed on both sides of the strip.

The present embodiment takes the structure shown in fig. 2 as an example, that is, takes an optical fiber sensor as an example, and the description continues on the strip steel jitter removing apparatus.

In fig. 2, the device comprises a base 1, a terminal connecting device 2, a cable 3, a support 4, an optical fiber sensor 5, a round hole 6, a strip steel 7, a shockproof tripod 8 and a slide rail 9, wherein the support 4 is arranged on the base 1, the optical fiber sensor 5 is arranged at one suspended end of the support 4 and is arranged above the strip steel 7, and the strip steel is irradiated on the strip steel 7 by the optical fiber sensor 5 to detect the shaking amplitude of the strip steel. The shock-absorbing tripod 8 serves to improve the stability of the stand 4.

The bracket can also comprise a guide rail, and the strip steel amplitude detection sensor is arranged on the guide rail. The strip steel amplitude detection sensor can move on the guide rail, and the position of a light beam irradiated by the optical fiber sensor on the strip steel is further adjusted. Generally, the light beam of the optical fiber sensor needs to be near the central axis of the strip steel, namely, the light beam needs to be in the middle position of the strip steel. The optical fiber sensor can be conveniently and rapidly moved to the upper side of the middle position of the strip steel through the guide rail so as to conveniently acquire the target shaking amplitude of the strip steel.

The controller can adopt a PLC controller, the controller is generally arranged in a control room, and a certain distance is reserved between the control room and a strip steel production line, so that the strip steel shaking detection assembly further comprises terminal connecting equipment, and the terminal connecting equipment is respectively connected with the strip steel amplitude detection sensor and the controller. The terminal connecting equipment is communicated with the strip steel amplitude detection sensor through a cable, and the controller is communicated with the terminal connecting equipment through the cable.

When the strip steel jitter detection assembly detects the strip steel jitter amplitude, the jitter amplitude detected each time can be used as a target jitter amplitude, an average value of actual jitter amplitudes of preset times can be used as a target jitter amplitude, an average value of actual jitter amplitudes in a preset time period can be used as a target jitter amplitude, and the target jitter amplitude can be determined according to actual conditions.

When the strip steel shakes, the shaking amplitude can be reduced by increasing the tension of the strip steel. Therefore, the strip steel shaking detection assembly sends the target shaking amplitude to the controller, and the controller determines the target tension parameter of the strip steel according to the target shaking amplitude. The controller sends the target tension parameters to the tension control adjusting equipment, and the tension control adjusting equipment adjusts the tension of the strip steel according to the target tension parameters. The tension control adjustment device may be a controller of the speed of the tension roller.

In summary, the band steel jitter elimination apparatus provided by the embodiment includes a band steel jitter detection assembly, a controller and a tension control adjustment device, the band steel jitter detection assembly detects the jitter amplitude of the band steel, the controller determines the target tension parameter of the band steel according to the jitter amplitude, and then the tension control adjustment device adjusts the tension of the band steel, so that the band steel can be tensioned, the fluctuation amount of the band steel in the target direction is reduced, the probability of scratching of the band steel caused by tension fluctuation is effectively reduced, and the yield quality and the yield are improved. Under the better condition, the method can even avoid the band steel from being scratched, and further improves the yield, the quality and the yield.

Based on the same inventive concept, the present embodiment provides a method for eliminating the steel strip jitter as shown in fig. 3, which includes steps S31-S34.

And step S31, acquiring the target shaking amplitude of the strip steel in the target direction.

And step S32, determining whether the jitter of the strip steel exceeds the limit according to the target jitter amplitude and the acquired target amplitude limit value.

And step S33, when the vibration of the strip steel exceeds the limit, determining the target tension parameter of the strip steel according to the target vibration amplitude.

And step S34, adjusting the tension of the strip steel according to the target tension parameters.

In step S31, a target jitter amplitude of the strip steel in the target direction is obtained, which includes steps S41 and S42.

And step S41, acquiring the actual shaking amplitude of the preset times of the strip steel in the target direction.

And step S42, determining a target shaking amplitude according to the actual shaking amplitude of the preset times.

The band steel shaking detection assembly is used for obtaining the shaking amplitude of the band steel in the target direction every time, the actual shaking amplitude of the band steel in preset times can be averaged to obtain the average shaking amplitude, and the average shaking amplitude is used as the target shaking amplitude.

Of course, the actual shaking amplitude of the strip steel in the target direction within the preset time period may also be obtained, and the target shaking amplitude is determined according to the actual shaking amplitude within the preset time period. Or the actual shaking amplitude of the strip steel within the preset time period in the target direction for the preset times can be obtained, and the target shaking amplitude is determined according to the actual shaking amplitude within the preset time period for the preset times.

For example, setting the preset number of times to 10 times, the actual shake amplitude of each time can be obtained as Y1, Y2, Y3, Y4, Y5, Y6, Y7, Y8, Y9, Y10, and then the target shake amplitude Y can be obtained according to the following formula.

For another example, if the number of times of shaking is acquired in a period of 1 minute and 13 times of shaking are acquired within a certain 1 minute, the actual shaking amplitudes at each time can be obtained as Y1, Y2, Y3, Y4, Y5, Y6, Y7, Y8, Y9, Y10, Y11, Y12, and Y13, and then the target shaking amplitude Y corresponding to each minute can be obtained according to the following formula.

In step S32, determining whether the jitter of the strip steel is over-limit according to the target jitter amplitude and the obtained target amplitude limit value, including steps S51-S53.

And step S51, obtaining the thickness of the strip steel.

And step S52, acquiring a target amplitude limit value according to the thickness of the strip steel.

And step S53, determining whether the band steel jitter is over-limit according to the target jitter amplitude and the target amplitude limit value.

There are various types of strip steel, mainly classified by the thickness of the strip steel. For example, the thickness of the strip may be 0.5mm to 1.0mm, 1.0mm to 1.5mm, 1.5mm to 2.0mm, 2.0mm to 2.5mm, etc.

The jitter requirements of the strip steels with different thicknesses are different. That is, the target amplitude limit values corresponding to the strip steels with different thicknesses are different. Therefore, the corresponding target amplitude limit value is determined according to the thickness of the strip steel, and whether the strip steel shakes over the limit is further determined.

In step S52, obtaining the target amplitude limit according to the thickness of the strip steel includes steps S61-S63.

Step S61, determining a target compensation amount according to the thickness of the strip steel;

and step S62, determining a target amplitude limit value according to the target compensation amount and the set basic amplitude limit value.

For the strip steels with different thicknesses, the corresponding shaking intensities are different. For example, when the thickness of the strip steel is small, the strip steel is easy to shake, the shaking amplitude is large and is larger than the basic amplitude limit value, and therefore compensation is needed. Therefore, the corresponding target compensation amount can be determined according to the thickness of the strip steel, and whether the vibration of the strip steel exceeds the limit value is determined according to the target vibration amplitude and the target amplitude limit value.

For example, when the thickness is in the range of 0.5mm to 1.0mm, the target compensation amount is M1. When the thickness is in the range of 1.0mm to 1.5mm, the target compensation amount is M2. When the thickness is in the range of 1.5mm to 2.0mm, the target compensation amount is M3. When the thickness is in the range of 2.0mm to 2.5mm, the target compensation amount is M4.

When the thickness of the current strip steel is in the range of 0.5mm-1.0mm, the basic jitter amplitude is X1, the jitter compensation amount is determined to be M1 according to the thickness, therefore, the final jitter amplitude limit value is X1+ M1, and then the target tension parameter is determined according to X1+ M1.

After the tension of the strip steel is adjusted according to the target tension parameter, the method further includes steps S71 and S72.

Step S71, acquiring the actual tension parameters of the strip steel;

and step S72, performing linear control on the tension of the strip steel according to the target tension parameter and the actual tension parameter.

In order to determine whether the tension of the strip steel meets the requirement, the actual tension parameter of the strip steel can be obtained, the tension of the strip steel is linearly controlled according to the target tension parameter and the actual tension parameter, and the overlarge difference between the target tension parameter and the actual tension parameter of the strip steel is avoided.

The tension of the strip steel is adjusted mainly by the tension roller, so that the speed of the tension roller of the strip steel can be linearly controlled according to the target tension parameter and the actual tension parameter, and the tension of the strip steel is adjusted.

A description will now be given, by way of example, of a method for eliminating the jitter of the strip steel provided in the present embodiment.

Step 1: setting a target amplitude limit value of the sensor as X and an actual feedback value of the optical fiber sensor as Y on a man-machine interaction picture; in the present invention, the actual value is averaged over 10 times.

Step 2: dividing the thickness of the strip steel of the production line into 4 ranges:

the thickness of the strip steel is less than 1.0mm after the thickness of the strip steel is less than 0.5mm, and when the thickness of the strip steel is within the range, a compensation value M1 is automatically issued;

the thickness of the strip steel is 1.0mm <1.5mm, and when the thickness of the strip steel is within the range, a compensation value M2 is automatically issued;

the thickness of the strip steel is less than 2.0mm after 1.5mm, and when the thickness of the strip steel is within the range, a compensation value M3 is automatically issued;

the thickness of the strip steel is less than 2.5mm and 2.0mm, and when the thickness of the strip steel is within the range, a compensation value M4 is automatically issued;

and step 3: adding the additional value of M1-M4 to X according to the current thickness of the strip steel according to the judgment in the program;

and 4, step 4: when the thickness is less than 1.0mm and less than 0.5mm, calculating the difference between X and Y, defining the output value as N and the speed of the tension roller as VL;

and 5: adding the actual value of N to the previous section of tension controller T; t is a tension set value T of the tension roll_{_set}And the PI controller output of the actual value difference T _ act.

T＝PI(T_{_set}-T_act)

The tension roller speed setting value is denoted as V _ Set.

In summary, in the embodiment, the optical fiber sensor is used for detecting the strip steel shaking amount, the strip steel amount is effectively converted into the output speed of the tension controller through a corresponding calculation formula, and finally, the strip steel shaking is improved through the speed adjustment of the tension roller, so that the strip steel scratch is eliminated.
