Description

[Detailed Description of the Invention] The present invention relates to an end-of-day accumulation device for accumulating cards, forms, etc.

FIG. 1 shows an example of a conventional integration device.

In FIG. 1, paper sheets 1 are conveyed horizontally in the direction of arrow A by conveyor belts 2 and 3, and are then changed in the conveyance direction by rollers 4 and 5 to the direction of arrow B, and placed in a stacking device. , a stop plate 6 that can be fixed at any position depending on the size of the paper sheet 1
The sheets are stopped and stacked one after another on the pedestal 7 with the paper surface facing the water.

In FIG. 1, a pedestal 7 is fixed at a position where a large amount of paper sheets can be accumulated from rollers 4 and 5, which are the conveyance exits, and a stop plate 6 is moved from side to side according to the size of the paper sheets. It is possible to accumulate a large amount of paper sheets that are roughly the same size as the receiving table 70.

With this method, large paper sheets can be stacked without any problem, but as shown in Figure 2, for small paper sheets below a certain size, the distance between the pedestal 7 and the rollers 4 and 5 is determined by the size of the paper sheets. The paper sheets become larger than the paper sheet 7 and the stacked paper sheets get stuck in the gap between the stop plate 7 and the stacked paper sheets, causing the stacking order to change, turning over, or paper sheets flying out from the stacking mechanism. The disadvantage was that it was prone to instability.

Therefore, as a general method, the pedestal is moved according to the amount of paper sheets to be accumulated.

If it is vertically movable and the distance between the top surface of the stacked paper sheets and the conveyance exit is set to an appropriate position, stable stacking can be achieved.

If there are many different sizes of paper sheets and their unit weights vary greatly, use a simple method of moving the pedestal 7 up and down using a spring or the like to keep the distance between the conveyance exit and the top surface of the paper sheets within a range that allows for stable stacking. However, there are new drawbacks that are complicated and expensive, such as adopting a system in which the vertical movement of the pedestal is controlled by the detection output of the position of the top surface of the paper sheet.

Therefore, the purpose of the present invention is to improve the conventional drawbacks and provide a simple paper sheet stacking device that can stably stack paper sheets of various shapes and sizes regardless of the amount of stacking. be.

Next, the present invention will be explained in detail with reference to FIGS. 3 and 4, which show an embodiment of the present invention.

FIG. 3 shows a configuration in which a removable and attachable stacking mechanism for small paper sheets is added to the stacking device of FIG. 1.

In FIG. 3, the paper industry 1, which has been conveyed horizontally on the paper surface in the direction of arrow A by conveyor belts 2 and 3, is transported by rollers 4.
The conveyance direction is changed in the direction of arrow B at , and the paper sheet 1 is placed in the stacking mechanism, stopped by a stop plate 8 that can be fixed at any position depending on the size of the paper sheet 1, and suspended by a spring 10 to adjust the stacking amount. The sheets are sequentially stacked on a pedestal 9 that moves up and down accordingly, with the paper surface horizontal.

For paper sheets of a size that cannot be stacked by the stacking mechanism for small paper sheets, the stacking machine for small paper sheets is removed and stacked in the state shown in FIG. 1.

Since the unit weight of paper sheets is different between the smallest size paper sheet and the largest paper sheet size that can be used in the small paper sheet stacking mechanism, the amount of paper sheets transported relative to the number of sheets stacked is different. Although the distance between the outlet and the top surface of the paper sheets varies, the size of the pedestal 9 and the spring 10 are selected so that the paper sheets can be housed within a range that allows stable stacking.

In addition, the size of the pedestal 70 has been adjusted so that the size of the pedestal I can be used to stably accumulate a large amount of paper sheets even when the stacking mechanism for small paper sheets is removed and the stacking is performed in the state shown in Figure 1. The distance from the conveyance exit to the edge of the pedestal 7 is selected.

FIG. 4 is a view of the small paper stacking mechanism viewed from the front x--x as shown in FIG. 3.

As explained above, according to the stacking device of the present invention, a large amount of paper sheets can be stacked stably with a simple structure regardless of the shape, size, and amount of paper sheets stacked by pressing the button to stack paper sheets. An integrated device is obtained.
