Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet sorting and feeding device for sorting a desired number of sheets while transporting a single sheet, for example, a single sheet discharged from a continuous sheet cutting device is transported. However, it is divided into desired number of sheets,
It is provided on the transfer path to the stacker device or is incorporated in the stacker device.

[0002]

2. Description of the Related Art Conventionally, a single piece sheet sorting process is performed by moving a sheet mounting table of a stacker device in the sheet width direction (for example, Japanese Patent Publication No. 3-38991, Japanese Patent Publication No. 4-991).
36993).

[0003]

For this reason, conventionally, the sheet sorting process can be performed only in a portion such as a stacker device that holds the sheets, and can be performed on the way of the sheet transfer path. There was an inconvenience that it could not be done.
SUMMARY OF THE INVENTION It is an object of the present invention to provide a sheet sorting / feeding device that solves this problem.

[0004]

A sheet sorting and feeding device according to the present invention is located in a sheet conveying path in parallel with a straight path and in parallel with the straight path, and extends obliquely in a separating direction. An oblique path is provided, and a rotating body such as a transfer roller for transferring the paper in the transfer direction of both paths is provided in each of these paths so that the roller can be moved up and down.
The rotating body corresponding to the path is in the lowered position to transfer the paper.
And the rotor corresponding to the other path is in the raised position.
To wait .

Further, the above-described orthogonal path and the oblique path are constituted by circulating conveyor belts, and further, a guide for guiding the side edge of the sheet to the opposite side end of the oblique path from the orthogonal path. It is preferable to provide the member in parallel with the orthogonal path.

[0006]

When the rotating body is lowered with respect to either one of the direct path and the oblique path, the paper is transferred in the transfer direction of the path corresponding to the lowered rotary body. When this path is the direct path, The paper is transported in the same direction as it is, but in the case of a skew path, it is shifted in the diagonal direction, and by selecting the descending rotating body, the paper is shifted in the width direction for sorting processing. You can
