Abstract

PURPOSE:To surely feed paper sheets from the paper sheet in the forefront end, by providing a guide member, which presses the paper sheets to a straightening bed, in the vicinity of the front end of the paper sheets straightened in an almost vertical condition on the paper sheet straightening bed. CONSTITUTION:Straightening paper sheets 7 almost in a vertical condition on a paper sheet straightening bed 1, a device, which presses the paper sheet from its rear end by a pressing plate 8, generates friction force between the paper sheets 7 in the forefront end and a feed roller 2. While the device provides a guide plate 4 which presses the front end part of the paper sheets 7 to the straightening bed 1. Further the device provides the pressing plate 8, which presses the paper sheets 7 from the upper when the paper sheets 7 are horizontally piled building a layer on a mounting bed 5, and a guide plate 6 warping the rear end of the mounting bed 5 to the upper by a predetermined angle. In this way, the paper sheets are surely fed sheet by sheet from the paper sheet in the forefront end.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a paper sheet feeding device for sequentially feeding paper sheets arranged vertically on an alignment table or stacked on a stacking table. .

(Prior Art) Conventionally, as shown in FIG. 2, one type of paper sheet feeding device has been used to align paper sheets in an almost upright state on a sheet sorting table 1, and press the rear end to align the front end of the paper sheets. There is one that generates a frictional force between the paper sheet and the feed roll 2 and sequentially feeds out the paper sheets.

However, in the conventional paper sheet feeding device as described above, as shown in the same figure (al K), several sheets at the front end of the aligned sheets are simultaneously placed between the feeding roll 2 and the tip of the alignment table 1. If the sheet falls and causes a paper jam, or as shown in the same figure (b), the sheet behind the frontmost sheet supported by the feed-out auxiliary roll 3 falls first and continues. There was a defect in that a paper jam was created along with the remaining leading edge paper leaf that fell.

(Object of the Invention) The present invention has been made in order to eliminate the defects of the conventional paper sheet feeding device as described above, and it is possible to align or stack paper sheets in an orderly manner by simply adding a simple member. It is an object of the present invention to provide a paper sheet feeding device that can be inserted into a sheet feeding and feeding member.

(Summary of the Invention) In order to achieve the above-mentioned object, the paper sheet feeding and discharging device of the present invention uses an alignment table or a paper sheet dispensing device to place the paper sheets near the leading edge of the aligned sheets or near the lower layer of the rear end of the stacked sheets. A guide is provided to press against the feeding member.

(Examples) The present invention will be explained in detail below using examples shown in the drawings.

8f! FIG. 1 is a configuration diagram showing an embodiment of the paper sheet feeding and discharging device of the present invention, in which paper sheets arranged in an almost upright state on a paper sheet sorting table 1 are pressed from the rear end and the leading edge and the paper sheet are A frictional force necessary for feeding is generated between the roller and the feeding roll 2.

Further, the feed-out auxiliary roll 3 is used to force the leading edge of the aligned paper sheets into the feed-out roll 2.

In the above-mentioned apparatus, the leading edge of the sheet behaves as shown in FIG.

In order to solve this problem, the sheet feeder of the present invention presses the free edge of the sheet near the front end of the sheet toward the sheet 1, so that the profile of the front end of the table 1 has a shape corresponding to y. A guide 4 is provided.

By doing this, the front ends of the aligned paper sheets are forced to line up along the profile of the tip of the alignment table, and the paper sheets enter the feed roll 2 sequentially starting from the front edge, so that the paper sheets are stacked.
, b can be significantly reduced.

Conventionally, the profile of the alignment table 1 was generally such that the border between the horizontal part and the guide part near the delivery roll was connected at a predetermined angle, as shown in FIG. As shown in FIG. 1, it would be more effective to connect a portion of a circle with an appropriate radius to further enhance the function of the guide 4 of the present invention.

Although the present invention has been described above using an example in which the present invention is applied to a paper sheet feeding device that is equipped with a substantially horizontal paper sheet aligning table and that aligns paper sheets in a vertical shape, the present invention is not limited to this only.
As shown in the figure, the paper sheets are stacked almost horizontally on the paper sheet stacking table 5 (this is also applicable to the device shown in FIG. By providing a curved guide, the lower layer of the trailing end of the piled sheets is pressed toward the feed roll 2, so the piled sheets are sequentially pushed into the feed roll 2 starting from the lowest layer. I can do it.

(Effects of the Invention) Since the present invention is configured as described above, it is possible to align or stack paper sheets near the feed roll of the paper feed device or the like by simply adding an extremely simple guide member. Since the alignment or stacking state of paper sheets can be optimally controlled, this method has a remarkable effect in minimizing the occurrence of paper tangles at the core.
