Abstract

PURPOSE:To minimize the overshoot in the warm-up operation of a heat roll by controlling the surface temperature of the heat roll on the basis of the resistance value of a soft-touch sensor and a machine input voltage. CONSTITUTION:The surface temperature T1 of the heat roll 1 at some point t1 of time is detected from the resistance value R1 of the soft-touch sensor 2 or thermoelectromotive force, and its signal is sent to a computing device 4 through a detector 3. The computing device 4, on the other hand, inputs the detection signal of an input voltage at the point t1 of time from a detector 5 which detects the machine input voltage to calculate automatically the time (tII-tI) for the temperature rise of the heat roll 1 up to control temperature TII by using said detection signal and signal from the sensor 2. Then, the turn-on time of the lamp heater of the heat roll 1 is controlled by the obtained signal through a controller 6 and a solid-state relay 7.

- By controlling the voltage of the power supply with
It was designed to keep the surface temperature of the cell constant at all times. Therefore, if the temperature sensor itself has low sensitivity, when the heat rule warms up,
As shown in Part 1, the surface temperature of the heat roll varies from room temperature T1 to the optimum temperature for fixing) R-low temperature T2 (R1)
It was common practice for the lamp heater of the heat rule to continue to turn on even after reaching the temperature indicated by TI(R2), and then return the temperature to the temperature indicated by TI(R2) above. Therefore, there is a drawback that the warm-up time of the heat roll becomes longer than necessary, and power is wasted during that time.
