Abstract

(57) [Abstract] [Purpose] To provide a paper feeding device capable of smoothly feeding stacked papers sequentially from the bottom regardless of the cut state of the papers. [Structure] By forming a side wall 2a and a bottom portion 2b on the side of a lead-out port 3 with which an end portion of the paper storage portion 2 on the paper delivery side abuts with an acute angle, when the papers are stacked in the storage portion 2, The edge of the upper sheet does not match the edge of the lower sheet, the upper sheet is regulated to a position retracted from the lower sheet, and the lowermost sheet 1a is drawn out by the rotation of the feed roller 5. When the paper is sent out from the paper, the hanging portion 11 at the front end of the upper paper 1b is prevented from obstructing the paper feeding.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a paper feeding device that sequentially pulls out stacked papers from the bottom.

[0002]

[Prior art]

 In general, it is often the case that the address, name, etc. are written by hand on paper such as postcards for funerals and seat cards at banquets. However, since handwriting work is often covered by the elderly, it is desirable to automate this work. In this case, a paper feeding device is conceivable in which an outlet is provided at the lower end of the side of a storage unit that stores a large number of sheets stacked vertically and the sheets at the bottom of the stacked sheets are sequentially drawn out through the outlet.

As such a paper feeding device, as shown in FIG. 3, a feeding means 13 such as a feeding roller is arranged in the accommodating portion 12, and the feeding means 13 is brought into contact with the lower surface of the lowermost paper 1a to cause contact friction. It is conceivable that a method of leading out from the housing portion 12 by

By the way, in many cases, strictly speaking, the end face of paper is not cut at right angles to the surface. When the cutter cuts the paper, a part of the paper is pressed by the cutter, and at that time, the paper is bent and deformed due to the flexibility of the paper itself. In addition, especially in the case of banquet seats, the four edges may be purposely cut to obtain a golden edge.

When the end faces of such papers are enlarged, the ends are hanging down as shown in the figure. Therefore, when these are stacked, the hanging part of the front end of the upper paper 1b is the front end of the lower paper 1a. Overlay and engage. Therefore, when the lower paper 1a is sent out from the outlet 14, the upper paper 1b also tries to come out together as indicated by the dotted line. Since the outlet 14 is usually formed to be slightly thicker than the thickness of one sheet of paper, in this case, the phenomenon that the two sheets of paper 1a and 1b are clogged at the outlet may occur.

[0006]

[The purpose of the device]

 SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned drawbacks and to provide a paper feeding device that can smoothly feed stacked sheets from the bottom regardless of the cut state of the sheets.

[0007]

[Means for achieving the purpose]

 In order to achieve the above-mentioned object, the paper feeding device according to the present invention is provided with an outlet at a side lower end of a storage unit for accommodating and stacking a large number of papers vertically and sequentially from the lowermost paper of the stacked papers. In the paper feeding device for leading out from the outlet, a side wall on the outlet side with which the end of the paper of the storage portion on the outlet side abuts and a bottom portion are formed in an acute angle shape.

It is preferable that the side wall of the housing portion on the outlet side is arranged vertically.

[0009]

[Action and effect]

 According to the above configuration, since the side wall on the outlet side and the bottom with which the end portion on the outlet side of the paper abuts are formed in an acute angle, when the paper sheets are stacked in the storage section, the edge of the upper paper sheet is And the edges of the lower paper do not align, and the upper paper is restricted to a position retracted from the lower paper. Therefore, the hanging portion of the front end of the upper paper does not cover the front end of the lower paper but rides on the upper surface of the front end of the lower paper. Therefore, when the lowermost paper is fed out from the outlet by the rotation of the feed roller, the hanging portion at the front end of the uppermost paper does not hinder the feeding. Therefore, the paper is fed smoothly.

When the side wall on the outlet side of the storage unit is arranged vertically, the bottom portion is inclined so that the outlet side becomes lower. Therefore, when storing the paper in the storage unit, the end portion of the paper on the outlet side is drawn. Easy to align so as to abut the side wall.

Embodiment FIG. 1 shows a main part of a paper feeding device. In this paper feeding device, a lead-out port 3 is provided at a lower end of a front side wall 2a of a storage part 2 for accommodating a large number of papers 1 stacked vertically. At the same time, the feed roller 5 is arranged in the opening 4 formed in the bottom portion 2b, and the feed roller 5 is rotationally driven so that the paper 1a at the lowermost stage is sequentially drawn out from the above-mentioned outlet port 3. A paper receiving roller 6 is disposed behind the paper.

In addition, a pressing member 7 is arranged in the storage unit 2 so as to press the stacked papers 1 downward to obtain a sufficient frictional force between the papers 1 and the feed roller 5. ing. The pressing member 7 includes a roller portion 8 directly placed on the paper 1, a supporting member 9 for rotatably supporting the roller portion 8, and traveling rollers 10 provided on both sides of the supporting member 9. And is configured to move up and down along the front side wall 2a. The feed roller 5 is linked to a drive mechanism (not shown).

Next, the accommodating portion 2 is formed such that the angle α between the side wall 2a on the side of the outlet 3 with which the end of the paper 1 on the outlet side abuts and the bottom 2b forms an acute angle.

Therefore, when the sheets are stacked in the accommodating section 2, the edges of the upper sheet and the lower sheet are not aligned, and the lowermost sheet 1a and the upper sheet 1b in FIG. 2 are not aligned. As shown in, the upper paper 1b is restricted to a position retracted from the lower paper 1a. Therefore, the hanging portion 11 at the front end of the upper paper 1b does not cover the front end of the lower paper 1a, but rides on the upper surface of the front end of the lower paper 1a.

Here, when the driving mechanism is operated to rotationally drive the feed roller 5, the lowermost paper 1 a is fed out from the outlet 3 by the frictional force between the feed roller 5 and the lowermost paper 1 a. . At that time, since there is no engagement relationship between the front ends of the lowermost paper 1a and the uppermost paper 1b, the hanging portion 11 at the front end of the uppermost paper 1b causes no obstacle to the feeding of the lowermost paper 1a. It does not become. Therefore, the paper is fed smoothly.

When the front side wall 2a of the accommodating portion 2 is arranged vertically as shown in the figure, the bottom portion 2b is inclined so that the front side becomes lower, so that the paper 1 is accommodated in the accommodating portion 2. At this time, it is easy to align the end portion of the paper 1 on the side of the outlet 3 so as to contact the side wall 2a.
