Abstract

PURPOSE:To aim at improving the accuracy of sheet transfer, by making the tilt of a sheet smaller to its forward direction in turn, according as moving in close to the first-third sheet conveying devices. CONSTITUTION:Tilting a sheet 11 as far as an inclination alpha in its forward direction, a first sheet conveying device 1 is set up at a position where a lower roll is nearly congruous with a conveying plate surface, and successively a second sheet conveying device 1' is tilted by a smaller inclination alpha' than that alpha of the first sheet conveying device 1 and likewise a third sheet conveying device 1'' is tilted as well as so as to become a yet smaller inclination. In addition, in order to make a criterion to align the sheet, a guide 3 is installed in parallel with the forward direction of the sheet. Doing like the above, sheet alignment as transferring sidewise to the forward direction of the sheet is performed in an even so efficient manner with a simple constitution and at high speed.

具合があった。In the conventional automatic paper alignment and conveyance device, as shown in Fig. 1(a)
, as shown in (b), a pair of conveyance rollers 1 or a paper conveyance means combining a roller and a sphere without a rotating shaft are arranged at an angle α with respect to the traveling direction of the paper,
When the paper is caught in this conveying means, the paper is conveyed diagonally, and the end of the paper hits the guide B, and the drag from the guide causes it to be aligned again in the normal direction of travel. However, in a paper aligning device with such a configuration, (1) when handling many different paper sizes and the amount of horizontal transport is relatively large; (2) when the paper transport speed is fast; and (3) when horizontal When trying to obtain a predetermined lateral transport amount with a short transport distance even if the directional transport amount is the same, etc.,
Because it is necessary to increase the inclination angle α of the conveyance roller or to strengthen the conveyance force, the drag from the guide increases, causing objects to climb up from the guide or not to be aligned along the guide and to be fed diagonally. There were problems such as paper jams and paper jams.

That is, it is sandwiched between the roller 1 and the sphere 2. Conveyance roller 1
is the angle α(
The paper 11 is rotated clockwise and advanced, so the paper is conveyed so that the leading edge of the paper touches the surface of the guide guide 3 at an angle α. Ru.

なっている。The sixth conveying roller 1'' and the sphere 2 are arranged close to the guide 6 in order to increase the buckling limit of the paper, and are always guided by a very weak force due to the inclination angle α'' of the rollers. The posture of the paper is arranged along the guide roller.

。In this way, each time the paper passes through several conveyance means, that is, conveyance rollers, it is rotated little by little so as to return to the original direction of travel of the paper and is conveyed toward the guide B. When the leading edge hits the guide B, it does so at a very small angle, so the force that forces the paper to hit the guide 3 is sufficiently small, and the paper is pushed against the guide more than necessary. This can prevent paper buckling and damage caused by this.

経て、プーリー６の回転を受けるようになっている。Since the conveying roller 1 is attached to the back side of the conveying plate 5 in an inclined manner, its shaft 4 receives the rotation of the pulley 6 via the universal joint 10 shown in FIG.

ない。The conveyance plate 5 is bent 180 degrees at its end to form a paper guide 6, and is bent at an angle relative to the thickness of the paper in order to fully utilize the stiffness of the paper and prevent buckling. Since the paper is designed to be guided with as few gaps as possible without interfering with conveyance, even thin sheets of paper are unlikely to buckle. Although the conveyance means in this embodiment is a combination of rollers and spheres, this is not necessarily the case.
Needless to say, a round roller or a roller made of urethane foam or the like may be disposed on the conveying plate.

る。In addition, in this embodiment, the paper conveying means consisting of six stages is tilted and weighted at an angle α'>α' with respect to the direction of paper travel, so that the pressure on the guide is small. However, it is also possible to use a two-stage structure consisting of the first paper conveyance means and the second paper conveyance means, and it goes without saying that a structure with four or more stages will also have similar or better effects.
