Document Type and Number:
Japanese Patent JP7072211
Kind Code:
B2
Abstract:
To provide a corrugated fiberboard sheet feeding device capable of matching a working position by means of a printer and a die cutter to a desirable position with respect to both of two sheets of corrugated fiberboard sheets fed out during one rotation of a printing cylinder.SOLUTION: A corrugated fiberboard sheet feeding device 2 feeds out two sheets of corrugated fiberboard sheets SH1, SH2 during one rotation of printing cylinders 30A, 31A and performs variable speed control of roller motors 90, 91, 102, 103 on the basis of a speed control pattern including an acceleration region, a constant speed region and a deceleration region for controlling rotation feeding rollers 124 to 127. The corrugated fiberboard sheet feeding device 2 differentiates a speed control pattern of the acceleration region applied to the first corrugated fiberboard sheet SH1 and the speed control pattern of acceleration region applied to the second corrugated fiberboard sheet SH2 and, thereby, at least either feeding timing of the first and second corrugated fiberboard sheets SH1, SH2 is changed.SELECTED DRAWING: Figure 8
