き揃えている。2. Description of the Related Art FIG. 11 shows an example of a conventional sheet aligning device in a sheet discharging device of a sheet feeding machine. A rack 13 is provided which moves integrally with a side jogger 10 which is given a swinging motion in the paper width direction of the discharged paper by a cam follower 8 and a lever 9 provided by a cam 7 provided on the paper discharge shaft. The paper aligning plate 1 is attached to the paper so that the falling sheets are aligned in the width direction.

ガー１０に対して相対的に移動し調節する。Such a sheet aligning device is provided on both sides in the sheet width direction. When the paper size to be printed is changed, the paper width adjustment motor 11 is driven to change the paper width direction.
The rack 13 moves relative to the jogger 10 and is adjusted by the pinion 12 directly connected to 1.

ように紙揃え状態が悪くなる。Therefore, when the paper size is small, the vicinity of the center (center of gravity) of the paper length can be aligned with the paper aligning plate as shown in FIG. 10 (b). However, when the paper size is large, as shown in FIG. 10A, the paper aligning plate 1 tries to align the position deviated from the center (center of gravity) of the paper 5, so that the moment to rotate the paper 5 is large. As a result, the paper alignment state becomes worse as in 5a.

ントとなりこれが大きい程紙揃えが悪くなる。As described above, when the paper aligning plate 1 presses the paper 5 to be printed at a position deviated from the center (center of gravity) of the paper size, the pressing force and the direction of the force. The product of the shortest distance to the center of gravity becomes the moment that rotates the paper 5 to be printed, and the larger this is, the worse the paper alignment becomes.

える必要があった。The discharged paper 5 is aligned by the oscillating motion of the paper aligning plates 1 provided on both sides in the paper width direction until it falls, but at the moment when the dropped paper 5 hits the paper aligning plate 1. Is different depending on whether it hits the left or right, and the moment that rotates the paper acts accordingly. Therefore, when the paper aligning plate 1 is fixed in the vertical direction as in the conventional case, it is necessary to manually replace the paper aligning plate 1 with a larger one when the paper size becomes large.

いる。According to the present invention, in the sheet discharging device of the sheet-fed machine, it is possible to prevent the paper alignment state from being deteriorated by giving a rotation moment to the paper by pushing the paper alignment plate at a position deviated from the center of gravity of the paper. An object of the present invention is to provide such a paper aligning device.
