BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for maintaining a roughness of a strip (CPC; center position control, CPC) illuminance, and more specifically, to detect a missed edge of a strip in a high speed continuous annealing process. In the procedure for preventing the stripping (hereinafter referred to as "meandering") to maintain the strip as a center part, the light emitting surface is automatically cleaned according to the illuminance of the light emitting surface during the process, the lamp is replaced, and the process is terminated. The present invention relates to an apparatus for easily replacing a lamp.

In general, a CPC used to detect and correct both edges of a strip is used for the preceding strip 101 and the trailing strip 101 having different steel grades and sizes for continuous operation in a continuous annealing process. Work continuously by welding.

In the middle of the strip length (e.g. approximately 4,600 m) of this continuous annealing process, a sipe is installed, as shown in FIG. 1A, which is equipped with a light receiver 105 placed on top of the strip, and It consists of the light emitter 104 provided in the lower part. In addition, the amount of light emitted from the lamp 106 of the light emitter 104 below the strip and the shadow boundary line are received by the light receiving unit 105 to detect and correct both edges of the strip. By recognizing both edges of the strip thereby, the reciprocal plays a very important role in aligning the strips in a straight line in the center of the rotating roll, leading to the strip center passing at high speed.

However, when foreign matter is adsorbed on the light emitting surface 107 of the light emitter 104 due to the high speed running of the strip 101, the illuminance of light generated is reduced, making it impossible to recognize normal edges of both strips. In addition, not only when the lifetime of the lamp 106 that emits light inside the light emitter 104 is exhausted, it also makes it impossible to recognize both edge portions of the strip.

If the light emitter 104 cannot be recognized due to poor illuminance for any reason as described above, strip meandering occurs and rolls out. Therefore, the strip edge part comes into contact with the equipment, causing breakage. There is a problem of causing a pause in the process. Therefore, in the case of reduction of illuminance caused by foreign matter, the light emitting surface 107 should be cleaned as soon as possible, and when the lamp 106 has reached the end of its life, it should be replaced with another lamp.

However, since the continuous annealing process is a high speed operation and a dangerous operation, in the case of the sippy close to the strip, the light emitting surface 107 is cleaned using the import cloth 108 as shown in FIG. 1B only after stopping the process. Alternatively, the lamp 106 may be replaced as shown in FIG. 1C. Therefore, the appearance of a simple method or device that can eliminate the decrease in the roughness is expected, but there has been a problem that there is a risk of downtime because there has not yet been published for such technology.

In addition, during normal operation, it is not possible to confirm whether the roughness is poor due to foreign matter or whether the roughness is poor due to the completion of the lamp 106 life. Therefore, there was a problem that can not take appropriate measures according to the cause.

The present invention has been made to solve the above problems, the illumination of the light emitter installed in the bottom of the strip is detected by the light receiver, if the illuminance is low during operation, first recognized by the adsorption of foreign matter and automatically applied to the brush By removing the foreign matter, if the illuminance still persists, the lamp is recognized as a defective lamp and automatically switched to the standby lamp, and it has a function to quickly return to normal illuminance even during the operation.

FIG. 3A shows only the left set of devices of the present invention, and as shown therein, the surface cleaner comprises a cylindrical light emitter 201, a brush 207, a rubber roll 205, and a motor 204. It is.

As shown in FIG. 3A, the cylindrical light emitter 201 is rotatably supported at both ends to accommodate lamps 202 and 203 and has a length corresponding to the lamp length. It is made of transparent glass, which transmits the lamp light to the outside and prevents dust or foreign matter from adhering to the surface of the lamp.

The brush 207 is provided in close contact with the surface of the light emitter 201. This brush serves to remove the foreign matter attached to the surface when the light emitter 201 rotates.

The rubber roll 205 is provided in close contact with the light emitter 201. In actual installation, it is preferable to be installed at a position that does not interfere with the brush 207, and serves to rotate by contacting the light emitter 201 by friction.

The motor 204 is connected to rotate the rubber roll 205. In this embodiment, although the motor 204 is used, various modifications are possible, and any mechanism capable of generating rotation such as a turbine, a rack, and a pinion can be adopted.

On the other hand, the lamp replacement portion, as shown in Figure 4a, is composed of a shaft 301, a lamp holder 407, and a motor 304.

Both ends of the shaft 301 are rotatably supported. The lamp holder coupled to the shaft and the lamp coupled thereto are rotated together by the rotation of the shaft.

The lamp holder 407 is installed at one side of the light emitter 201 outside the shaft 301 to install the lamps 202 and 203. The lamp holder 407 is provided with a lamp socket 408 of FIG. 4A so that the lamps 202 and 203 can be fastened.

The motor 304 is installed to rotate the shaft 301. Accordingly, the shaft 301 and the lamp holder 407 are rotated together by the rotation of the motor 304.

Consists of.                     

On the other hand, preferably, the illuminance detection unit is configured by adding an illuminance detection function to the light receiver 105 or is installed in addition to the light receiver 105. This is to save installation space by using the light receiver 105 which is already equipped. However, even if the illuminance sensing unit is installed on the lower side of the strip, that is, directly above the light emitter 104, the present invention does not depart from the gist of the present invention. In this case, since it needs to be controlled by a reference value different from the illuminance required in the light-receiver 105, only a little inconvenience arises.

In addition, preferably, the lamp replacement portion, as shown in Figure 6, the length of the shaft 301 is formed longer than the length of the light emitter 201, the lamp holder 407 is sliding on the surface of the shaft 301 It is configured to be freely fitted and supported. At this time, the lamp holder 407 is preferably provided with a lamp support 412 having a length corresponding to the length of the lamp (202, 203) is installed sliding freely in direct contact with the surface of the shaft 301. In this case, the brush 207, the light emitter 201, the lamps 202 and 203, the support 412, and the shaft 301 are viewed from the outside as shown in FIG. 3B, which is a cross-sectional view along the line AA ′ of FIG. 3A. The lamp holder 407 has an electrode plate 409, a lamp holder 407, and lamps 202 and 203 from the outside, as shown in FIG. 4B. The support 412 and the shaft 301 form approximately a kind of coaxial multilayer structure.

In this embodiment, since the lamp holder 407 and the lamps 202 and 203 are separated from the light emitter 201 by pulling the lamp holder 407 outward, the lamp can be easily replaced. In addition, when the lamp support unit 412 is provided, the sliding can be performed more smoothly, and an interference phenomenon that may occur between the shaft 301 and the lamps 202 and 203 during sliding can be prevented. I can protect it.

In addition, the lamp holder 407 is preferably fixed to the handle 418 to be used when sliding. Since the lamp holder 407 is heated to a high temperature during lighting, it is difficult to deal with it directly, and this inconvenience and safety problems can be solved by the handle 418.

In addition, a switch 307 is fixedly installed on the shaft 301, and a sensor 308 that detects the approach of the switch 307 is installed adjacent to the shaft 301, and the number of switches 307 corresponds to the number of lamps.

The pair of ball guides 413 in close contact with each other by the spring 414 is preferably configured to be connected to a power source. When the lamp holder 407 starts to rotate by the rotation of the shaft 301 by this configuration, the rotation starts when the electrode plate 409 which has supplied power to the lamp 202 is disconnected from the ball guide 413. When the ball guide 413 arrives at the electrode plate 409 of the lamp 203 to be turned on by a predetermined angle, the rotation is stopped, and the electrode plate 409 and the ball guide are caused by the elastic force of the spring 414. Complete contact is made between 413.

On the other hand, the transparent glass light emitter support portion 210 which is supported when rotating under the transparent glass light emitter 201 is provided on the base 401. In addition, a brush 20 is installed to gently clean dust and foreign matter from the transparent glass emitter 201 on both sides thereof, and is fixed to the brush fixing groove 208 by a brush fixing screw 209. . When the light receiver 105 recognizes the light emitted from the transparent glass light emitter 201 by the normal illumination, the transparent glass light emitter 201 is configured to perform a normal sippy function.

That is, the electrode support 403 is erected on the base 401 so that the electrode 405 can be turned on in the lamp 202 in use inside the transparent glass light emitter 201 located below the strip 101. The electrode support 403 is provided with an electric wire passage 416 moving along the ball guide groove 415, a spring 414, a ball guide 413, and a cover 404 for engaging the fixing screw. 411 is fixed, the ball guide 413 is a current through the electrode plate 409, the electrode plate 409 is fixed with a fixing screw 411 on the outside of the lamp holder 407, the lamp socket inside The lamp 202 and the standby lamp 203 being used in the 408 are located, and a lamp support 412 for supporting the lamp is provided.

In addition, when the control unit recognizes the end of life (OFF) of the lamp 202 being used in accordance with the signal of the upper strip 101, the shaft rotation motor 301 rotates under the instruction of the control unit. Then, the gear 305 and the shaft rotation gear 303 are driven, and the shaft 301 is rotated by the connection of the screw 306 connected to the shaft 301 inside the shaft rotation gear 305. At this time, the shaft support for rotating parts 302 is supported by the base support 402 on the left and right of the base 401, respectively. In addition, a stopper switch 307 for recognizing the operating position of the standby lamp 203 under the lamp holder 407 is assembled to the detection sensor support 406. When the stop condition is established, the shaft rotation motor 304 stops, and the standby lamp 203 emits light to achieve a normal seafaring function. Thereafter, a handle 418 is provided for replacing the lamp at the time of engagement or SD (see Fig. 6).

The controller controls the surface cleaning unit by driving the surface cleaning unit when the illuminance is insufficient, and then rotates the shaft rotation motor 304 by determining that the lamp is abnormal when the illuminance continues to be insufficient despite cleaning for a predetermined time, thereby rotating the gear 305 and the shaft rotation. Dedicated gear 303 rotates the shaft support body 310 and the lamp holder 407 together, after the shaft 301 is driven by the signal of the stop detection sensor 308 to detect and recognize the stop position When the driving lamp is stopped and the standby lamp 203 is rotated and turned on, the transparent glass light emitter 201 can be emitted while maintaining the function of the continuous process without empty time.

That is, according to the embodiment, the light receiver itself installed on the upper part of the strip is provided with a function of detecting the lamp light emitted from the light emitter and the function of checking the illuminance of the light, and when the amount of light below the standard illuminance is detected, Recognizing that the lamp emitting surface of the light emitter is contaminated, rotate the transparent glass and rotate it until it reaches the standard illuminance, and then wipe the contaminated part with a brush.If the illuminance does not exceed the standard even after predetermined time cleaning, the lamp life will be Recognizing that it is done, the standby lamp at the bottom is automatically shifted to the top to return and maintain the normal lamp illumination.

Hereinafter, the operation of the present invention will be described with reference to the accompanying drawings.                     

Light emitted from the lamp 202 in use of the light emitter 201 passes through both edges of the strip 101 and is recognized by the receiver 104 of the top of the strip. At this time, the light receiver 104 notifies the controller if there is an illuminance, for example, an illuminance amount of 80 lx or less, which may cause an error in maintaining the edges 101 of the strips in a straight line.

The controller determines that roughness of 80 lx or less is detected by adsorbing foreign matter on the light emitting surface of the transparent glass light emitter 201 and determines that cleaning is necessary. Accordingly, the light emitter rotating rubber roll 205 is rotated while the light emitter rotating motor 204 is rotated by the instruction of the controller, and the light emitter rotating surface 206 is in close contact with each other to gradually rotate the transparent glass light emitter 201. Then, the brush 207 continuously cleans the foreign matter and dust on the light emitting surface.

As a result, when the illumination intensity required to keep the strip 101 center through which the illumination intensity sensed by the strip upper light receiver 105 passes in a straight line, for example, 80 lx or more, cleaning is recognized as being completed, the light emitter rotating motor 204. ) Stops, and the brush 207 that has been cleaning the transparent glass light emitter 201 stops the operation.

On the contrary, even when cleaning is performed for a predetermined time or more, the illumination intensity of the transparent glass light emitter 201 is recognized as 80 lx or less, which is the case of the lamp 202 or more. At this time, the light receiver 105 of the upper part of the strip 101 which passes through sends a signal to a control part, and the control part recognizes the need to switch to the standby lamp 202, and rotates the shaft rotation motor 304. FIG. Then, the shaft support body 310 and the lamp holder 407 rotate together with the shaft 310 while the gear 305 and the shaft rotation gear 303 rotate in engagement with each other. The shaft 301 rotates in the shaft support groove 417 for smooth operation during this rotation. Then, the ball guide 413 for supplying power is moved up and down by the cushion of the spring 414. Then, the shaft rotation motor 304 stops when the stop detection sensor 308 that recognizes the stop position of the shaft 301 recognizes the arrival of the switch 307, and the ball guide 413 for supplying power is an electrode. The lamp 203 is turned on in connection with the plate 409. When the transparent glass light emitter 201 emits light, the light receiver 105 on the upper portion of the strip becomes an illuminance for normal operation, for example, an illuminance of 80 lx or more. The continuous annealing process operation is normally performed by detecting the.

In addition, the spent lamp 202 inside the transparent glass light emitter can be replaced using the replacement handle 418 attached to the lamp holder 407 during the idle time (see FIG. 6), thereby completing all operations.

Therefore, according to the present invention, the self-recognized illuminance measurement function automatically cleans the surface of the light emitter with a brush when the illuminance is lower than the appropriate illuminance (also poor illumination), and always maintains the standard illuminance or higher, and automatically detects a lamp abnormality and requires a down time. By allowing the standby lamp to be replaced without any change, in a continuous process in which continuous operation is performed at high speed, the strip center is constantly guided in a straight line with respect to objects of various sizes and steel grades, thereby preventing meandering by preventing meandering, By removing the trouble factor of the continuous annealing process, there is an effect of automatically preventing and solving the roughness problem in performing the continuous annealing operation.
