Field of the Invention The present invention relates to a winder temperature control device for controlling the cooling of a rolled material by cooling water. 2. Description of the Related Art A conventional winder temperature control device transports a rolled material by a roller table (rotary table) for transporting when controlling the winding temperature of a rolled material by a hot rolling mill. By opening and closing a number of spray (spray) valves disposed above / below the roller table and controlling the amount of cooling water falling on the rolled material, the temperature of the rolled material becomes a target temperature value. Control. According to this method, since the rolled material is controlled by opening and closing the spray valve while conveying the rolled material, the temperature control device opens the spray valve in advance according to the spray valve opening command, and the cooling water flows into the rolled material. It is necessary to detect the arrival time and to output a signal to open / close the spray valve based on the arrival time. Conventionally, a human outputs a spray valve open signal for each spray valve to a number of spray valves arranged on a conveying roller, and the time until the cooling water reaches the rolled material is visually measured. However, this time is used for control as a delay time of the temperature control device. [0005] For this reason, it is not possible to measure an accurate delay time for each spray periodically, and it is not possible to easily make an accurate delay time corresponding to aging of a solenoid valve or a water pipe. This was an error in the temperature control. SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and the cooling water is supplied to the transport roller by a water detector installed on the same plane as the transport roller. The time when the spray open signal is output from the winding temperature device and the time when the spray reaches the rolled material can be easily and accurately measured by detecting that the temperature has reached the temperature, and the control accuracy of the temperature control device is improved. It is an object of the present invention to provide a winder temperature control device that can be operated. [0007] A winder temperature control device according to the present invention is provided with a roller table attached to the winder for loading and transporting a rolled material, and mounted on an upper portion of the roller table. A cooling water spraying device that sprays cooling water on the rolled material and adjusts the temperature of the rolled material, a water detector that is installed on the same horizontal plane as the roller table and detects arrival of the sprayed cooling water,
A water arrival detector that determines the arrival of cooling water based on an output signal from the water detector, an electromagnetic valve connected to the water source side of the cooling water spraying device to control the flow of cooling water, and controls opening and closing operations of the electromagnetic valve. Solenoid valve opening / closing control by calculating the solenoid valve opening / closing control device, the solenoid valve opening command signal output from the solenoid valve opening / closing control device, and the cooling valve arrival signal output from the water arrival detector to calculate the operation delay time of the solenoid valve A cooling water delay detector that outputs an adjustment signal to the device is provided. Next, an embodiment of a winder temperature control device according to the present invention will be described. In FIG. 1, roller tables 3a and 3b are devices attached to a winder (not shown) and are devices for loading and transporting a rolled material (not shown). The cooling water spraying devices 1a and 1b are also called laminar sprays, and are installed above roller tables 3a and 3b and are provided with cooling water 10a and 10b such as laminar (leaf layer) water for the rolled material.
To adjust the temperature of the rolled material. The water detector 4 comprises a light projector 4a and a light receiver 4b shown in FIG. 2, is installed on the same horizontal plane as the roller tables 3a and 3b, and normally receives an optical signal 9 emitted from the light projector 4a. However, the optical signal 9 is the cooling water 10a, 10
This is a device that detects the arrival of sprayed cooling water by being blocked by b. The water arrival detector 5 is a device that is electrically connected to the water detector 4 and determines the arrival of the cooling water 10a, 10b based on the light reception signal 11 output from the water detector 4. The solenoid valves 2a, 2b are provided with cooling water spraying devices 1a,
This valve is connected to the pipe on the water source side of 1b and controls the flow of the cooling water 10a, 10b. Also, the solenoid valve opening / closing control device 1
2 is electrically connected to the solenoid valves 2a and 2b,
This is a device for controlling the opening and closing operations of the a and b. The cooling water delay detector 7 is connected to the electromagnetic valve opening / closing control device 12 and the water arrival detector 5, and the electromagnetic valve opening command signals 6a and 6b output from the electromagnetic valve opening / closing control device 12 and the water arrival detector 5 This is a device that calculates an operation delay time of the solenoid valves 2a and 2b from the cooling water arrival signal 8 output from the controller and outputs an adjustment signal 7a to the solenoid valve opening / closing control device 12. Then, the arrival of the cooling water 10a, 10b sprayed from the cooling water spraying devices 1a, 1b is detected by the water detector 4, and the opening and closing operations of the solenoid valves 2a, 2b are controlled to control the cooling water spraying devices 1a, 1b. The solenoid valve opening command signal 6 output from the solenoid valve opening / closing control device 12
a, 6b and the cooling water arrival signal 8 output from the water arrival detector 5, calculate and save the operation delay time of the solenoid valves 2a, 2b, and adjust the adjustment signal 7 output from the cooling water delay detector 7.
The opening / closing operation start time of the solenoid valves 2a and 2b is controlled by a. As described above, according to the present embodiment, the time required for the cooling water to reach the rolled material from the output of the cooling water spray valve opening signal from the control device is accurately detected. It is possible to detect in advance the change in the rolled material arrival time for each solenoid valve due to the change in the water pressure of the cooling water or the like, and it is possible to improve the accuracy of temperature control of the rolled material using the cooling water. According to the present invention, the operation accuracy of the temperature control device of the winder can be improved.
