However, these conventional techniques use a method of photographing the inside with a camera as a performance, but there is a problem that actual utilization is not achieved because it is not linked to a measured value.

It is an object of the present invention to promptly check and confirm rolls without checking with naked eyes for state monitoring by temperature measurement and performance of rolls according to the present invention.

The roll checker for monitoring the condition of the performance roll of the performance roll according to the present invention includes a roll checker body and a sensor part installed on the roll checker body for measuring a roll gap, a roll banding, a roll alignment state, A temperature sensor unit mounted on the roll checker body to sense a surface temperature of the roll, a camera unit having four cameras installed on upper and lower sides of both sides of the roll checker body, and a sensor unit, a temperature sensor unit and a camera unit A central processing unit installed in the roll checker body to synchronize and process received signals; a transmitter installed in the roll checker body to transmit a synchronized signal from the central processing unit to an external control unit; And a battery unit for supplying the battery.

Here, the central processing unit may further include a remote control receiver for processing an input signal of the external remote controller.

Further, the roll checker body is further provided with a camera for checking the spraying state of the cooling spray.

The roll checker for condition monitoring and performance monitoring of a roll of a performance roll according to the present invention is characterized in that the roll gap of the rolls provided on the fixed segment strand 10 of the continuous casting machine, the roll banding, the roll alignment state, And it is possible to quickly check and confirm the rolls without checking them with the naked eye by synchronizing them with the camera photographs.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 2 is a conceptual view of a roll checker for monitoring the condition of a performance roll of a roll according to a preferred embodiment of the present invention.

2, the roll checker for condition monitoring and performance monitoring of a roll of a performance roll according to the present invention includes a roll checker body 100, a sensor unit 200, a temperature sensor unit 300, a camera unit 400 A central processing unit 500, a battery unit 600, and a transmission unit 700.

First, the roll checker body 100 serves as a basic base on which the respective components are installed, and is inserted into the playing track along the dummy bar chain.

The sensor unit 200 is installed on the roll checker body to measure the roll gap, the roll banding, the roll alignment state, and the roll rotation state, and includes a gap sensor, a rotation sensor, an alignment sensor, Is transmitted to the central processing unit 500 through the sensor signal relay module.

The temperature sensor unit 300 is installed on the roll checker body to sense the surface temperature of the roll, and continuously measures the temperature of the roll.

In addition, four cameras are installed on the upper and lower portions of both sides of the roll checker body so as to confirm the damage of the roll, and a camera having a wide angle lens of 120 degrees or more and 1.3 million It is preferable to install the photographic lens so as to obtain a photograph of the above-mentioned pixels.

In particular, the roll checker body may further include a camera for checking the spraying state of the cooling spray.

The central processing unit 500 is installed inside the roll checker body 100 to synchronize signals received through the camera unit 400 and the sensor unit 200 and the temperature sensor unit 300 .

The synchronized signal from the central processing unit 500 is transmitted to an external control unit. The transmitting unit 700 serves to transmit the signal, and can selectively use the wire / wireless method.

In addition, the central processing unit 500 may be supplied with power through a built-in battery unit 600, and the central processing unit 500 may further include a remote control receiving unit 800 for processing an input signal of an external remote control .

3 is a conceptual diagram showing a camera unit according to a preferred embodiment of the present invention.

As shown in FIG. 3, four camera 110 cameras are disposed on both sides of the upper and lower sides, and the spraying state of the cooling spray can be checked through two cameras 120 arranged inward from both directions.

4 is a schematic plan view of a roll checker for monitoring the condition of a roll of a performance roll according to a preferred embodiment of the present invention.

As shown in FIG. 4, the signals acquired by the sensor unit 200 including the gap sensor, the rotation sensor, and the alignment sensor are collected by the sensor signal relay module and are processed and stored in the central processing unit.

Here, when the time of the camera unit and the roll gap sensor is synchronized and the performance of the camera unit is performed, the moving image and the photograph of the equipment are secondarily processed when they are stored in the sensor value and the management database measured by the sensor, So that it is possible to display at which position the image is photographed. Likewise, the temperature value measured by the roll temperature sensor can also be stored to allow the user to check the status of each roll.

Further, in the process of measuring the roll gap, the pinch roll 20 pulling out the dummy bar chain 90 is lifted when the roll checker body passes through the rolled checker body 100 before the roll checker body 100 passes, It is difficult to check the roll state.

Therefore, the surface of the pinch roll and the operation state of the pinch roll can be confirmed by using the image of the synchronized camera unit.

FIG. 5 is a conceptual diagram illustrating a process of measuring the temperature of a roll of a performance roll and the signal processing of a roll checker for status monitoring by playing according to one preferred embodiment of the present invention.

As shown in FIG. 5, since the time of the camera unit and each sensor unit are synchronized, the roll can be detected from the output signal of the sensor unit measured in the progress direction of the roll checker body, The photographing position can be known.

As described above, according to the present invention, it is a principal technical idea to provide a roll checker for condition monitoring by measuring the temperature of a roll and playing a roll, and since the above-described embodiment is only one embodiment, The true scope of the claims should be determined by the claims.
