Description

[Detailed Description of the Invention] The present invention relates to a paper alignment device for aligning paper sheets such as postcards on two adjacent sides.

In order to apply paper leaf-shaped mail to an automatic processing device such as stamping, it is necessary to neatly align the mail on two adjacent sides and feed it to the device, and for this purpose, a aligning device is used. FIG. 1 is a diagram showing a conventional alignment device. In the figure, a paper sheet holding means (guide plate) 1 consisting of an inclined bottom surface and a rear surface connected thereto vibrates while holding a mail piece 2. I am made to do so. 2 and 3 are also diagrams showing conventional examples,
In FIG. 2, the alignment operation is performed by vibrating diaphragms 3 and 3' provided on the back and bottom surfaces of the guide plate 1. Further, in FIG. 3, rotating elliptical rollers 4, 4' are provided on the back and bottom surfaces of the guide plate 1 so as to protrude from each surface, thereby imparting vibration to the mail and aligning it. however,
In these conventional alignment devices, since vibrations are simultaneously applied to all mail items placed on the guide plate, it has been difficult to apply an effective alignment effect to each individual mail item. Furthermore, the devices shown in FIGS. 1 and 2 had the disadvantage of increased noise.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a paper aligning device that can provide effective aligning action to individual mail pieces and that produces less noise.

According to the present invention, it is possible to obtain a paper sheet aligning device that is provided with rollers having spiral projections on the back and bottom surfaces of the guide plate 1.

Next, the present invention will be described in detail with reference to the drawings of an embodiment of the present invention. FIG. 4 shows an embodiment of the present invention, in which rollers 5 and 5' having spiral projections are provided on the back and bottom surface of the guide plate 1. As the rollers 5, 5' rotate, the positions of the protrusions shift in accordance with the rotation, so that individual vibrations can be applied to the mail pieces 2 on the guide plate 1.

FIG. 5 is a diagram showing a roller having helical protrusions according to the present invention, and the surface of the roller 5 is provided with helical protrusions 6 and 7 that move in different directions. If the rotary shaft 8 is now rotated in the direction of arrow A, the mail will receive forces in the vertical direction sequentially by the spiral protrusions 6 and 7, and will also receive forces in the directions of arrows B and C alternately. In other words, vertical and horizontal vibrations are applied to the mail, resulting in an effective alignment effect. Further, the temporal average of the force in the left and right directions obtained by the spiral protrusion rollers is zero since the rollers have spirals in different directions, and the entire mail piece does not move laterally.

In the embodiment, one spiral protrusion roller was used on each of the back surfaces of the guide plates, but it goes without saying that the number of rollers may be increased depending on the size of the paper sheets, etc.
