[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a paper sheet stacking device that sequentially stacks paper sheets such as banknotes and slips conveyed by a conveying means in a stacking section and temporarily stores them. It is.

[Conventional technology]

Recently, automatic teller machines, for example,
As disclosed in Japanese Patent No. 69897, paper sheets such as banknotes and slips are allowed to fall freely in a stacking section and are sequentially stacked. In addition, there is Japanese Patent Application No. 106596/1987, recently filed by the present applicant, which describes a system in which paper sheets such as banknotes and slips being conveyed by a conveying means are deposited one after another without allowing them to fall freely.

A card C, which will be described later, is conveyed into the space of the yoke 9. The distal end side of the yoke 9, that is, the ejection opening side, is made free so that it can escape when a large number of bills M are handled, and the base end side is supported by a spring 13. On the other hand, when the number of bills M handled is small, for example, one, and the fork member described later pushes the bill M on the tray 2, if there is no gap between the upper surface of the tray 2 and the pulleys 10, 10', the belt 12 , 12', or if the bill M is weak or creased, the bill M cannot overcome the resistance of the belts 12, 12' and Since the banknotes M are crushed and cannot be pushed out to the discharge port 1, the banknotes M cannot be pushed out to the ejection port 1.
There is a slight gap H between the outlet side of the tray 2 and the tray 2.
has been established. In order to provide this gap H, the base end side of the yoke 9 is prevented from moving upward by a stopper 14. 15 and 15' are guide plates for banknotes M and slips T fixed on both sides of the machine frame 6, and guide plates for banknotes M transported from the first transport means 3 and slips transported from the second transport means 4. This prevents the tip of the T from bending upward. Reference numeral 16 denotes a guide means for feeding the card C, which has been checked for verification by the control section, onto the slip T, and this guide means 16 is connected to a third transport means 17 for transporting the card C that has been checked for verification; The card C conveyed by the conveyance means 17 is held obliquely on the tray 2 as shown by the two-dot chain line in FIG.

By driving the tray 2, the comb-shaped portion provided on the tray 2 is reciprocated. The shutter 20 and the fork member 21 are interlocked, and when the fork member 21 starts, the shutter 20 is held in the state shown by the two-dot chain line in FIG. At this point, the shutter 20 descends and holds down the banknotes M, etc., to prevent them from flying away in the wind.

[Problem that the invention seeks to solve]

In the case of a structure in which paper sheets are deposited in the stacking section by free fall, static electricity is likely to be generated on the paper sheets, and the equipment,
In particular, paper sheets may adhere to the vicinity of the discharge port, and paper sheets tend to be piled up irregularly in the stacking area, and especially if the paper sheets are folded, it becomes difficult to stack and align them.

In addition, in the structure shown in Figures 4 and 5, in order to prevent the leading edge of paper sheets such as banknotes and slips conveyed from the conveying means onto the tray from curling upward, the machine frame is Although guide plates are fixed on both sides, for example, when handling small numbers of paper sheets, the leading edge of the paper sheets on the tray may become deformed between the tray and the guide plate. The trailing edge of the paper sheets on the tray may move forward or curl.

As a result, particularly when handling thin paper sheets such as banknotes and slips, the leading edge of the succeeding paper sheet tends to collide with the rear end of the preceding paper sheet, which may cause a jam.

An object of the present invention is to prevent misaligned sheets and cards from being piled up one after another on a tray, whether the number of sheets handled is small or large.

[Means for solving problems]

The purpose of the above is to install an arm as a swinging member and a pulley provided on the sheet ejection side of this arm on a shaft provided on the machine frame on the reverse paper ejection side above the tray where paper sheets are stacked. A paper sheet taking in and conveying means is swingably provided, and a link that constitutes a parallel link mechanism together with the arm is disposed between the arm serving as the swinging member and the machine frame, and this parallel link mechanism This is achieved by connecting a sheet guide member to the moving end of the paper sheet guide member.

[Effect]

The sheet taking in and conveying means swings up and down depending on the amount of sheets piled up on the tray. However, the sheet guide member always maintains a constant distance between the lower surface of the pulley and the lower surface of the sheet guide member regardless of the amount of sheets accumulated on the tray due to the action of the parallel link mechanism. To prevent sheets of paper stacked on a tray from falling unevenly and from curling upward at the leading edge.

〔Example〕

As an embodiment of the paper sheet stacking apparatus of the present invention, FIGS. This will be explained with reference to Figure 3. In Figures 1, 2 and 3, the 4th
The same parts as those in FIG. 5 and FIG. 5 are omitted, and only the take-in and conveyance means, which is the main part of the present invention, is shown in an enlarged manner.Since the left and right sides have the same configuration, only one will be explained.

This intake conveyance means 23 is rotatably attached to the machine frame 32 and has a rotating shaft 25 provided with a pulley 24.
an arm 26 as a swinging member whose proximal end is pivotally attached to the rotating shaft 25; a pulley 27 rotatably attached to the inside of the tip of the arm 26; It is composed of a pulley 24 fixed to the rotating shaft 25 and a belt 28 stretched between the pulley 24 and a belt 28 for transmission.
The taking-in and conveying means 23 applies a conveying force to banknotes and slips sent from a conveying means (not shown) by rotation of its belt 28, and takes these onto the tray 2.

A link 29 is provided on the banknote sending side of the arm 26.
are arranged substantially parallel to the banknotes M deposited on the tray 2. A paper sheet guide member 30 is attached to the center of this link 29 to prevent the leading edge of the banknotes M stacked on the tray 2 from curling upward. Further, the arm 2 is attached to the other end of the link 29.
A link 31 parallel to 6 extends in the same direction, and the terminal end of this link 31 is rotatably attached to the machine frame 32 via a shaft. The above-mentioned arm 26 and links 29 and 31 constitute a parallel link mechanism, the details of which are shown in Figures 2 and 3.
This will be explained with reference to the schematic diagram shown in the figure.

First, with the arm 26 as a reference, a link 29 and a link 31 are provided which can rotate around the axis A of the roller 24, the axis B of the pulley 27, the axis C of the link 29, and the axis D of the machine frame 32, =,
The lengths of these arms 26, links 29 and 31 are determined so that ==, and a parallel link mechanism is constructed.

With this configuration, the heights of the axis B of the pulley 27 and the axis C of the link 29 are always maintained in a constant relationship.

Now, if the position of the axis D of the machine frame 32 is selected so that the axis B of the pulley 27 and the axis C of the link 29 are at the same height, the axis C of the link 29 will be independent of the height of the axis B of the pulley 27. is kept at the same height as the axis B of the pulley 27.

Therefore, when the lower surface of the paper sheet guide member 30 and the lower surface of the pulley 27 are kept on the same surface, for example, even if the amount of banknotes M to be handled is small as shown in FIG. Even when a large amount of paper sheets is accumulated, the distance between the lower surface of the pulley 27 and the lower surface of the sheet guide member 30 is always maintained at the same height.

As a result, as shown in FIG. 1, the banknotes M conveyed onto the tray 2 in the direction of the arrow are
Then, due to the feeding force of the belt 28, the paper sheets are piled up under the sheet guide member 30 and come into contact with the shutter 20 shown in FIGS. 2 and 3, so that the front ends are properly aligned and stacked.

In the above description, only banknotes were described as paper sheets, but slips can also be stacked on the tray in the same way as banknotes.

By configuring as described above, even when handling a small number of paper sheets such as banknotes and slips conveyed from the conveyance means, the leading edge of the paper sheets on the tray can be positioned between the tray and the paper sheet guide member. Therefore, the leading edge of the trailing sheet will not collide with the trailing edge of the preceding sheet, and the sheets will be stacked smoothly, preventing the occurrence of jams, and a large amount of sheets will be deposited on the tray. Even paper sheets in a folded state can be stacked properly.

〔Effect of the invention〕

As explained above, according to the present invention, regardless of whether the number of sheets to be handled is large or small, the sheets can be stacked one after another on the tray without becoming irregular or curled.
