The air supply fan rotation speed control system, the air supply fan rotation speed control method, a gravure printing machine

摘要

PROBLEM TO BE SOLVED: To provide an air supply fan speed control system for reducing energy consumed in a dryer according to the operating condition of a gravure printing machine.;SOLUTION: In the air supply fan speed control system 1, it is determined that the gravure printing machine 10 is in a small stopping condition and the rotational frequency of the air supply fan 21 is reduced, in the case the air supply fan speed control device 2 detects that an impression cylinder 5 is in the removed condition from impression cylinder information 41 from a position sensor 5a during the normal operation of the air supplying fan 21 of the dryer 81. Further, the opening of a steam amount control valve 25 is controlled for controlling the amount of steam supplied to a heat exchanger 23 for heating external air supplied to the dryer 81 based on temperature information 47 measured by a resistance thermometer bulb 29 arranged in a flow passage 22 four supplying hot air to the dryer 81 via the air supply fan 21.;COPYRIGHT: (C)2012,JPO&INPIT
