Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a paper processing device, and more particularly to a printing device that prints and outputs data from a computer.
The present invention relates to a paper processing device that outputs printed paper as is, or multiple sheets of paper that are bound and output as required.

Conventionally, this type of paper processing device has been marketed under the name of a booking machine by an office machine manufacturer or other specialized manufacturer. The method involves cutting continuous folded paper into sheets for use in forms, and then automatically binding the cut sheets into multiple sheets using a wire. Only continuous sheets of paper can be processed, which is why traditional sheet paper cannot be used. In this case, the outputted sheets are normally stored in a stacker and processed by hand, such as binding.

Furthermore, with conventional paper processing devices, this is possible only for the type of paper that performs the binding shown in Figure 1, and cannot be applied when a mixture of paper to be bound and paper that does not need to be bound is output as described above. Another problem was that the efficiency was extremely poor.

For this reason, a device as shown in FIG. 1 was devised.

That is, in the figure, paper 1 sent from a printing device is sent to a paper processing device by first feed rollers 2 and 7.

If the fed paper 1 needs to be bound, the direction conversion guide 3 is set at the position shown by the solid line, and the second feed rollers 4, 4' are moved along the upper surface of the conversion guide 3.
The paper is fed in the direction of the arrow 5 by the arrow 5, and the paper is stacked correctly by the stopper 6.

When the stacked sheets reach a predetermined number, the stapler mechanism 7 is operated to staple the ends of the sheets, and the stopper 6 is activated, and the stapled sheets are transferred to the third feed roller 8,
Discharge by 8'.

Further, when a sheet of paper that does not need to be bound is detected, the direction changing guide 3 is rotated and displaced to the position indicated by the dotted line to change the direction of the sheet 1 downward, and the paper guide 9 moves the sheet 1 to the fourth position.
is sent to the feed rollers 10, 10', and sent out in the direction of arrow 11.

However, the above structure has problems in that paper jams often occur when changing the direction of paper travel, and the stacker is made up of two stages, which increases the size of the device, resulting in a complicated structure and high cost.

The present invention has been made in view of the above-mentioned problems, and its purpose is to make it possible to quickly and accurately process paper output from a printing device, and to provide a simple and inexpensive paper processing method. The goal is to provide equipment.

It is an object of the present invention to provide a stacker for stocking paper with a pinch roller that presses the paper against the stacker by moving its shaft and conveys the paper at least in the pressed state, and a state in which the pinch roller is not in pressure contact with the paper. A stopper that aligns the edge of the paper and opens the edge of the paper while the pinch roller is in pressure contact with the paper, a drive source that drives the pinch roller and the stopper, and a drive source provided in the stacker section. This can be achieved by providing a paper processing device having a binding mechanism.

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 2 is a front view showing the configuration of the paper feeding device of the present invention.

In the figure, paper 1 is fed in the direction of arrow 1' and is fed by first feed rollers 2, 2'.

The fed paper is normally discharged in the direction of arrow 15 between switching roller unit 12 and feed rollers 13 and 14.

The structure and operation of the switching roller unit 12 will be explained using FIGS. 3A and 3B.

The fed paper 1 is normally transferred to the feed roller 13.1.
4 in the direction of arrow 15.

FIG. 3A shows a state diagram when paper is sent out without binding, and the pinch rollers 16 and 17 are the feeding roller 1.
In this case, the paper stopper 18 is lifted and the paper is smoothly discharged in the direction of arrow 15 in the figure.

FIG. 3B is a diagram illustrating the operation of the switching roller unit 12 of the binding holder.

That is, by energizing the rotary linenoid 19, the lever 20 is rotated downward, while the pinch roller 16.
17 is moved upwardly by the fulcrum 23.24 of the arm 21.22 and away from the feed rollers 13,14.

A stopper 18 provided at the tip of the arm 22 is moved downward by the stopper arm 25 and has the function of stacking the sheets 1 in front of the sheets 1 with their end surfaces aligned in a fixed position.

The leading end of the paper 1, which is sequentially fed by the feed rollers 2 and 2', is stopped by the stopper 18.

When a predetermined number of sheets are stacked, the stapler head 26 shown in FIG. 2 is actuated in response to a signal from the above device to staple the sheets at the ends of the sheets.

At the same time as the spelling is completed as described above, the excitation of the rotary lenoid 19 is released.

When the excitation is removed, the pinch rollers 16 and 17 descend again and contact the feed rollers 13 and 14, and at the same time the stopper 18 is lifted upward and the paper is ejected to the outside.

The stapler head 26 is automatically operated by the stapler head drive unit 27 in response to the signal from the edge.

The wire rod to be supplied to the stapler head 26 is continuously supplied by a wire spool 28.

As explained above, according to the paper processing device according to the present invention, it is possible to quickly and accurately process the paper output from the printing device into paper that needs to be bound and paper that does not need to be bound, and A paper processing device with a simple structure and low cost can be obtained, and its effects are extremely impressive.
