Description

[Detailed Description of the Invention] The present invention relates to an improvement of a paper sheet stacking device suitable for stacking paper sheets, particularly thin pieces such as banknotes.

In recent years, automatic cash handling machines have become widespread, and currency exchange machines, payment machines, deposit machines, etc. are being put into practical use one after another.

This type of automatic cash handling machine usually has a structure in which banknotes are inserted into an input slot and taken in one by one by a supply/take-in device, and are stacked horizontally in a stacking chamber of a stacking device. ing.

However, in the conventional paper sheet stacking device, the first
As shown in the figure, the front wall portion of the stacking chamber a located in the banknote carrying direction is simply configured as a fixed plate.

On the other hand, banknotes P are often stored in wallets and are therefore often curled in the center.

Therefore, if the curled banknotes P' are once stacked in the stacking chamber a in a state where they are shifted in the carrying direction, the front end of the banknotes P' remains lifted, and subsequent banknotes P collide and jam. This has caused problems such as bending or bending from the curled portion.

The present invention was developed based on the above circumstances, and its purpose is to provide a paper sheet stacking device that can reliably stack even folded paper sheets such as banknotes. That is.

An embodiment of the present invention will be described below with reference to FIGS. 2 and 3.

In the figure, reference numeral 1 denotes a carry-in device that carries in banknotes P as paper sheets taken in one by one by a supply/take-in device (not shown).
This carry-in device 1 consists of upper and lower conveyor belts 2 and 3, and is configured to sandwich the central portion of a banknote P between these mutually opposing surfaces and convey it to the left in the figure.

Further, as shown in FIG. 3, the flat conveyor belts 2 and 3 are wrapped around a convex roller 4 having a large diameter at the center and a concave roller 5 having a small diameter at the center, so that the banknotes P can be curled by themselves. Upper and lower conveyor belts 2 and 3 are used to curl in the direction that corrects the direction.
is curved in the width direction, so that the banknotes P are curled and bent into the stacking chamber 6.

The above-mentioned accumulation chamber 6 is provided near the terminal end of the carrying-in device 1, and includes a front wall portion located on the carrying-in direction side of the banknotes P and the banknotes P...
The bottom part supporting the... is composed of a front belt 7 and a bottom belt 8 stretched to form a substantially L-shape.

The front belt 7 is inclined by about 30 degrees so that the upper end is located outward, and the front belt 7 and the bottom belt 8 are driven by a roller 9 rotating clockwise in the state shown in FIG. The banknotes P carried in from the carry-in device 1 run in the opposite direction (to the right in the figure) with respect to the carrying-in direction.

Further, the rear wall of the accumulation chamber 6 has a regulating plate 1 whose lower end projects downward from the banknote supporting surface of the bottom belt 8 and also serves as a discharge gate.
Consists of 0.

Since the banknotes P carried in from the carry-in device 1 are held between the curved upper and lower conveyor belts 2 and 3, they are curled to correct their own curling direction and are then carried into the stacking chamber 6 with a stiff body.

At this time, when about 2/3 of the banknotes P have entered the accumulation chamber 6, the original curl of the banknotes P is not a problem and the banknotes P have sufficient rigidity, but when the remaining 1/3 reaches the uneven roller 5, The straightening effect of step 4 disappears, and the inserted banknote returns to its original curled state as shown in FIG.

Then, the banknotes P' are temporarily stacked with the front end a riding on the inclined surface of the front belt 7.

However, since the front belt 7 and the bottom belt 8 are running in the direction of the arrow in order to return in the opposite direction to the carrying direction,
The banknote P' is gradually transferred rightward along the front belt 7, so that the front end a is always corrected by the front belt 7 to the state PI/ shown by the two-dot chain line.

Therefore, the position of the front end a of the curled banknote P' can be corrected as in the conventional case, and the next banknote P carried in is the curled banknote P'.
′, and then the front end a is further piled up in the upper left direction, and there is no possibility that people will fall into a vicious cycle one after another.

Further, the bottom part is also applied with a rightward force by the bottom belt 8, and all the accumulated banknotes P... are applied along the regulation plate 10.
This results in a well-organized and good accumulation.

In the above-mentioned embodiment, the bottom part of the accumulation chamber is made up of the bottom belt 8, which runs in the opposite direction to the carrying direction, but if there is no need to move it to the next process, this part Even if it is just a fixed wall, the effect of the front belt 7 is large, so it is sufficient for practical use.

In addition, it goes without saying that the present invention is not limited to the above-mentioned embodiments, and that various modifications can be made without changing the gist of the present invention.

As explained above, the present invention is a gauze leaf stacking device that stacks paper sheets that are brought in horizontally one by one into a stacking chamber in a sequential manner, in which a part of the stacking chamber is It is formed of a belt, and the belt is configured to run in a direction opposite to the direction in which paper sheets are brought in when they are stacked.

Therefore, it is possible to accumulate paper sheets such as banknotes that are curled and folded in a sufficient manner for practical purposes, and it is especially useful if adopted in automatic teller machines such as currency exchange machines, payment machines, and deposit machines. It has the effect of
