Title:
輪転機の停電時制御方法及び停電時制御装置
Document Type and Number:
Japanese Patent JP3577288
Kind Code:
B2
Abstract:
The apparatus for controlling, in a power failure, a rotary press (Fig.1) that separately drives a printing section (CT1,CT2) and a folding section (FD) with independent drive sources (M), pulls a printing material (W) that is being braked in a paper feeding section (SP1,SP2) at least by the folding section, brings a blanket cylinder (BC) of the printing section into contact with the printing material to produce printing impressions by changing over the braking of the printing material to a braking mode with a constant braking force upon interruption of power feeding due to a main power failure, detecting a voltage drop caused by the power failure to output a power failure signal, changing over to a battery power supply (12), separating a blanket cylinder that is at press from the printing material, and decelerating and bringing to a halt a printing material pulling mechanism (OT) at the folding section within a predetermined time.
