HOT-AIR TEMPERATURE CONTROL METHOD IN HOT-AIR DRYING SYSTEM FOR ADHESIVE AGENT

摘要

PROBLEM TO BE SOLVED: To provide a hot-air temperature control method in a hot-air drying system for an adhesive agent, which efficiently supplies hot-air having the optimum temperature without requiring any idling operation.;SOLUTION: A hot-air temperature t at an air outlet port 12a in a hot-air generator 10 is detected by a thermocouple 14 and when the hot-air temperature t is lower than a set temperature, an inner heater 13 is driven. In a standby treatment mode, the inner heater is controlled through preheat control by a timer T1 to retain the hot-air temperature within a given range at all times. In an operation treatment mode, the control of the inner heater 13 is changed from the control through the timer T1 into an operation mode and the hot-air having a temperature within the optimum range is sent for a given period of time by another timer T2 at all times without requiring any idling operation.;COPYRIGHT: (C)2003,JPO
