Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic sheet feeder having a sheet sorting function for automatically performing a sorting operation performed before sheets are fed to an automatic sheet feeder.

[0002]

2. Description of the Related Art At present, various kinds of papers for advertising and advertisements are printed on photographic print bags, newspapers, etc. (hereinafter, "paper" means leaflets, printed materials, photographic prints after development, and negative films are returned to customers. It is meant to mean a leaflet or the like for advertising in a print bag.) Since the number of sheets is large, it takes a lot of time and effort to manually remove one sheet from each of the same type of sheets and combine various sheets into one set.

Therefore, in order to shorten the folding work time, an automatic paper feeder has been proposed which automatically collects various kinds of paper as one set.

This automatic paper feeder is provided with a plurality of insertion ports into which sheets are inserted, and the sheets inserted from these insertion ports are carried out from a single carry-out port with a certain time lag. By doing so, various types of sheets are placed in the receiving box so that they can be folded as they are. For this reason, a flat paper feed tray is fixed to the automatic paper feeder toward the paper insertion port, and paper is loaded on the paper feed tray.

By the way, the paper fed from the paper feed tray is fed by a calling roller arranged inside the insertion slot.
In order to pinch and convey one by one (so-called overrun prevention),
The worker had to sort out the leaflets and load them on the paper feed table, and this sorting work required labor and skill. Further, when the paper is placed on the paper feed table, the worker has to hold the paper and move it toward the insertion port of the automatic paper feeder, so that the work efficiency is lowered.

The sorting work here means to stack the sheets on the paper feed tray so as to form a tile as shown in FIG. As a method of stacking in a tile shape, a method of shifting the paper 12 from the top to the bottom and inserting it from the top of the paper 12 as shown in FIG. 8 is also considered, but it is discovered when the paper 12 is jammed. Paper 12 that is hard to remove and jammed at the top
Has the drawback that it is difficult to remove. Therefore, generally, as shown in FIG. 2, a method of shifting the paper 12 from the top to the bottom is adopted.

[0007]

SUMMARY OF THE INVENTION In consideration of the facts described above, an object of the present invention is to provide an automatic sheet feeder having a sheet sorting function which can automatically sort sheets.

[0008]

According to another aspect of the present invention, there is provided an automatic sheet feeder having a sheet sorting function, which feeds sheets stacked on a mounting plate of a sheet feeding table toward a calling roller and then conveys the sheets. There are a plurality of unit type automatic paper feeders for nipping and conveying the sheet by means of the means, and further for ejecting the sheet from the outlet by means of an ejecting roller arranged at the end of the sheet conveying path formed from the calling roller to the sheet conveying means. In the combined automatic sheet feeder, a sheet feed table that is configured separately from the main body of the unit type automatic sheet feeder and is rotatably supported by the cabinet of the unit type automatic sheet feeder, and It is characterized in that it has an end plate which is disposed at a predetermined angle with respect to the placing plate and sends out the sheets stacked on the placing plate toward the conveying roller.

An automatic sheet feeder having a sheet separating function according to a second aspect of the invention is characterized by including an angle adjusting means for adjusting an angle between the end plate and the mounting plate.

[0010]

In the automatic paper feeder having the paper handling function according to the present invention, when the paper is loaded on the paper feed tray, the paper feed tray is automatically fed around the shaft member provided on the paper feed tray. While rotating in a direction away from the main body of the paper feeding unit, the rotation of the paper feeding table is stopped at a position where the end plate provided on the paper feeding table becomes substantially horizontal. Next, the sheets stacked in the horizontal state are placed so that the sheet surfaces are on the end plates, and the edges of the sheets are brought into contact with the placing plate. After the paper is set, the paper feed tray is pushed down toward the automatic paper feeder, and the placement plate of the paper feed tray is placed in a horizontal state. At this time, since the sheet is leaning against the end plate, the edge of the sheet slides on the placing plate and is stacked in a tile shape on the placing plate.
After that, it is sent out one by one toward the transport roller by the end plate arranged at a predetermined angle,
It will not be double-fed.
