Description

[Detailed Description of the Invention] This invention relates to a paper holding stand for a paper separation device that separates stacked paper sheets.

<Background> A paper sheet separation device that separates stacked paper sheets at their edges and counts the number of sheets, or divides and divides the sheets into predetermined number of sheets, includes a sheet holding device in which the sheets to be separated are arranged in a stacked manner. A table is provided.

The stacked sheets of paper to be separated are placed on the sheet holder so that the ends of the sheets protrude from the sheet holder, and Separation and counting operations of the leaf separator are performed. For this reason, for multiple types of paper sheets having various thicknesses and different paper qualities, the protruding end from the paper sheet holding stand is designed to allow each sheet to be separated, regardless of the type of paper sheet being separated. On the side of the plate where the separation operation is performed, rather than in a state in which they are in close contact with each other, it is necessary that appropriate gaps be formed between the paper sheets, and that the edges are aligned and held in an orderly manner to facilitate the separation operation. .
If the protruding ends of the paper sheets to be separated hang down excessively or are arranged in a disordered manner, it will be difficult to perform the separation operation, and a malfunction may occur during separation. It is necessary that the sheets are arranged in an orderly manner and that appropriate gaps are formed between the sheets.

FIG. 1 shows the configuration of the main parts of this type of paper holding stand that has been used conventionally.
An approximately trapezoidal portion is integrally formed at the end of the paper stacking section 12 in the direction in which the paper sheets 13 to be separated are fed.
Guide plates 14-1 and 14-2 are fixedly attached to opposite sides of this trapezoid at right angles to the plate surfaces, respectively.

The extension lines of the opposite sides of the trapezoidal part are set to intersect at right angles to each other, and the end of the paper sheets 13 to be separated stacked on the paper stacking section 12 is arranged to protrude from the edge 15 of the trapezoid. Ru.

When using such a sheet holder, if the sheets 13 to be separated stacked on the sheet holder are thick or the paper is stiff, the paper sheets 13 to be separated may be separated as shown in FIG. 2A. Even at the ends of the leaves 13, the sheets are hardly separated and no gaps are formed. When the length of the protruding end of the paper sheets to be separated is increased in an attempt to separate the paper sheets from each other, the paper sheets are pushed into the paper stacking section 12 by their own weight as shown in FIG. 2B. Although the entire sheet is bent at the end, a good gap between the sheets is not formed at the protruding end of the sheet, and the arrangement of the ends is also disordered.

On the other hand, if the paper sheets 13 to be separated are thin or weak, the entire protruding end of the paper sheets 13 from the paper stacking section 12 will hang down, making it difficult to perform the separation operation. state.

In order to solve this drawback, as shown in FIG.
A structure has been proposed in which the support plate 15 is fixed to a substrate 17 fixed to the paper stacking section 12 via a rotating holder 16. In this structure, the support plate 15 is rotatably attached to the paper stacking plate surface in a direction perpendicular to the paper stacking plate surface, centering on the end on the paper stacking section 12 side.
A support arm 18 is provided with a spring 19 and is attached between the support plates 15 and 5, so that the support plate 15 can be rotated elastically.

In this proposed method, when the paper sheets 13 to be separated are thick or stiff due to their paper quality, the stacked arrangement state is as shown in FIG.
The support plate 15 elastically rotates by a predetermined angle due to the weight of the paper sheets 13 to be separated, but at the end position of the paper sheets 13 to be separated, there is a gap between the support plate 15 and the lower surface of the stacked paper sheets 13 to be separated. is formed, and some gaps are created between the sheets at the protruding ends, but the gap formation and edge arrangement are not significantly improved.

Furthermore, if the paper sheet 13 to be separated is thin or has a weak paper quality, a gap will be created between the support plate 15 and the sheet sheet 13 to be separated, as shown in FIG. 6, for example. The ends of the leaves 13 hang down, and the ends of the sheets to be separated are not arranged in an orderly manner with the desired spacing for separation.

This invention solves the shortcomings of the conventionally proposed methods, and provides separation arrangement at the protruding edge of the paper sheet that is optimal for separating multiple types of paper sheets of various thicknesses and paper qualities. The present invention provides a paper sheet holding stand for a paper sheet separation device that can realize this state.

<Summary of the invention> In this invention, the paper sheet holding base of the paper sheet separation device extends from the end position of the paper stacking section onto the same plane as the paper stacking section and the stacking plate surface of this paper stacking section. and a paper edge holding section formed by.

This paper edge holding section has a shape in which a single elastic plate is folded back at a bent part, and the bent part is placed on the paper stacking part and one end of the bend is stacked on the stacking plate of the paper stacking part. It is positioned opposite to the end of the lower surface of the stack of paper sheets to be separated, and is fixed to the paper stacking section at the other end of the bend. One end side of the paper edge holding part, which is disposed in opposition to the end side of the lower surface of the stack of paper sheets to be separated, is formed at the end of the paper sheets to be separated by the weight of the paper sheets to be separated. It is configured to be elastically deformable into a curved surface corresponding to the curvature.

<Example> Hereinafter, the paper sheet holding stand of this paper sheet separation device will be explained in detail based on the example using the drawings.

FIG. 7 is a diagram showing the configuration of the main part of the paper sheet holding stand 20 of the paper sheet separating device of this invention.
is a paper stacking section 2 in which paper sheets 13 to be separated are arranged in a stacked manner.
2, and a paper edge holding section 23 attached to the end of the paper stacking section 22.

The paper edge holding portion 23 is formed by bending a single elastic plate, such as stainless steel, into a substantially U-shape.

The paper edge holding part 23 has a bent part 24 located on the paper stacking part 22 side, and in the embodiment, is fixed to a mounting body 22-T that is integrally formed at the end of the paper stacking part 22. installed. One end side of the bent portion 24 extends substantially on the same plane as the stacking plate surface 22-P of the paper stacking portion 22, and the end thereof is formed into a substantially trapezoidal shape.

This extended end side is in contact with the lower surface of the protruding portion from the paper stacking section 22 of the paper sheets 13 to be separated, which are stacked on the paper stacking section 22, as shown by the dashed line in FIG. Allotted.

The other end side of the paper edge holding part 23 bent at the bending part 24 is extended parallel to the one end side which is disposed facing the paper sheet 13 to be separated, and fixed pieces 23-F are provided on both sides thereof.
1,23-F2 is formed.

The paper edge holding section 23 is attached to these fixed pieces 23-F1, 2
3-F2, the mounting body 22-T of the paper loading section 22
It is fixed to, for example, by means of screws.

FIG. 10 shows a state in which the paper sheets 13 to be separated are stacked and set in a separated state, and since the paper edge holding section 23 is formed of an elastic plate, it protrudes from the end of the paper stacking section 22. It comes into contact with the end of the arranged sheet of paper 13 to be separated from its lower surface side, and comes into elastic contact with the sheet of paper 13 to be separated over the entire surface of the plate. Therefore, when the protruding ends of the stacked sheets 13 to be separated from the paper stacking section 22 are bent to form a curved surface of a predetermined curvature due to their own weight, the sheets to be separated in the paper edge holding section 23 are bent. One end side facing the leaf 13 is curved with a curvature corresponding to this curvature, and almost the entire surface elastically receives the paper leaf 13 to be separated which has been deformed into a curved shape.

For this reason, the leading ends of the paper sheets 13 to be separated, which are arranged to protrude from the paper edge holder 23 and are subjected to the separation operation, are arranged in an orderly manner without any disturbance, and there are appropriate gaps between each sheet. is formed, and the paper sheet 13 to be separated is held on the paper edge holder 23 in a state where a smooth separation operation can be performed at its protruding end.

In general, when the paper sheets 13 to be separated are thick or stiff due to the quality of the paper, the length of the portion of the paper edge holder 23 that contacts the paper sheets 13 to be separated is shortened, and the relatively short portion is used to separate the paper sheets 13. Even when the paper sheets 13 are held, a desired end state can be achieved by forming a desired gap between the paper sheets at the ends thereof and orderly arranging the sheets at their protruding ends.

On the other hand, when the paper sheets 13 to be separated are thin or the paper quality is weak, the paper sheets 13 to be separated are held in the paper edge holding section 23.
In order to make the formation and arrangement of paper gaps at the ends desirable, it is desirable to hold the paper sheets 13 to be separated at a predetermined curvature over a relatively long distance by increasing the length of the contact portion with the paper sheets 13. is necessary.

Since the paper edge holding part 23 of the paper sheet holding stand of this invention is formed by bending a single elastic plate, the selection of the material, the method of bending, and the extension from the bending part 24 to the paper sheet 13 to be separated are determined. By setting the length of the opposing end,
It is possible to easily create one with optimal retention characteristics depending on the paper thickness and paper quality of the paper sheets 13 to be separated.

In the paper sheet separation device, the end position of the paper sheet 13 to be separated, which is disposed protruding from the tip of the paper sheet holding stand, is as follows:
It needs to be set at a certain position within the sheet separator.

Therefore, while the edge of the paper sheet 13 to be separated is held at a fixed position, the paper edge holding section 23 can hold the paper sheet 13 to be separated.
If the contact portion is made longer, it is necessary to fix the paper edge holding section 23 at a position deeper than the paper stacking section 22, as is clear from the comparison between FIGS. 8 and 9.

FIG. 11 and its configuration show another embodiment of the paper sheet holding stand of the paper sheet separation device of this invention, which is most suitable for use in such cases. While holding the leading edge position X-X' constant, replace the paper edge holding parts 23-1 and 23-2, which have different contact lengths with the paper sheets to be separated, for the same paper stacking part 22. It has a structure that allows it to be installed.

In the example shown in FIG. 11, the mounting screw portion 31 is located at a position where the paper edge holding portion 23-1, which has the longest contact length with the paper sheets to be separated, can be attached to the mounting body 22-T of the paper stacking portion 22. -1 is formed on the mounting body 22-T. Therefore, the paper end holding portion 23-1 is fixed to the mounting body 22-T by the mounting screw portion 31-1 as shown by the solid line in FIG. 11.

On the other hand, the paper edge holding part 23-2, which has a short contact length with the paper sheets to be separated, is fixed to the mounting screw part 31-2 formed on the end side of the mounting body 22-T. . This fixed state is indicated by dotted lines in FIG.

In this attached state of the paper edge holding section 23-2, a gap is created between the boundary surface of the paper stacking section 22 with the attachment body 22-T and the paper edge holding section 23-2. However, in general, the paper edge holding portion 23 has a short contact length with the paper sheets to be separated.
-2 is used for paper sheets to be separated that are thick or stiff, so the inventors have determined that the presence of some gaps will not have any negative effect on the separation of the paper sheets. Ta.

As explained in each of the embodiments, in the paper sheet holding stand of this invention, the paper edge holding section 23 is formed of an elastic plate, and corresponds to the curvature of the curvature formed at the protruding end of the paper sheet to be separated by its own weight. It is elastically deformed and can hold the paper sheets to be separated on almost the entire surface. For this purpose, a desired gap is formed between the paper sheets at the separated ends of the stacked sheets to be separated, and the end portions of the paper sheets are arranged in an orderly manner.

Therefore, the separation operation can be carried out smoothly without any operational errors, and the paper edge holding section with the desired holding characteristics can be selected and used for multiple types of paper sheets of various paper thicknesses and paper qualities. It is possible to perform an optimal paper separation operation.

As explained in detail above, according to this invention, the protruding ends of the stacked paper sheets to be separated can be held in an optimal state for separating the paper sheets with a simple and strong structure, and furthermore, It is possible to provide a paper sheet holding stand for a paper sheet separation device that allows one to easily select and use one with optimal holding characteristics depending on the quality and thickness of the paper sheet by simply replacing parts.
