Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a banknote stacking mechanism mounted in, for example, an automatic teller machine, and a collecting mechanism for collecting detailed slips.

[0002]

2. Description of the Related Art A paper sheet stacking mechanism including a stacking section for stacking and stacking paper sheets conveyed one by one and a sending section for sending the paper sheets to the stacking section has high reliability. In order to secure, the tip of the paper sheets sent to the stacking unit
It is necessary to prevent the rear end of the paper sheet from interfering with the accumulated paper sheets and the rear end of the paper sheets. This must be taken into consideration, especially when handling paper sheets having a crease or curl tendency, or when static electricity is likely to occur due to high speed handling, and various realization methods have been devised.

As an example, there is Jikken 5-12209. According to this, the rotating impeller is arranged in the feeding portion and the trailing end of the fed paper sheet is knocked off to prevent interference with the succeeding paper sheet.

[0004]

In the above-mentioned conventional example, a rotating impeller is arranged in the feeding portion to achieve high reliability, but the impeller and its drive source are required, and in terms of cost. There was a problem. In addition, a space for mounting the rotating impeller is required, which is a constraint for downsizing the mechanism.

An object of the present invention is to provide a paper sheet stacking mechanism which can realize high reliability without disposing a member such as the conventional rotating impeller.

[0006]

In order to achieve the above object, a stacking unit for stacking and stacking paper sheets conveyed one by one, and a sending unit for sending the paper sheets to the stacking unit. In the paper sheet stacking mechanism, the loop sheet member in which the elastic sheet is looped is arranged in the feeding section, and when the paper sheet is sent to the stacking section, the loop sheet member is A part of the loop-shaped outer periphery of the loop sheet member comes into contact with the deformed and accumulated sheets, and the delivered sheets are guided along the other part of the outer periphery and accumulated in the accumulating portion. It is configured so that the deformation of the loop sheet member is released later.

Further, in order to maximize the effect of the loop sheet member, two or more loop sheet members are arranged outside the sandwiching / conveying means composed of rollers forming the feeding portion.

In this way, the paper sheets sent from the sending section to the stacking section deform the loop sheet member, and a part of the loop-shaped outer periphery of the loop sheet member comes into contact with the stacked paper sheets. This ensures that the trailing edge of the accumulated paper sheets is knocked down, and that the conveyed paper sheets are guided along the other part of the outer periphery, so that the conveyed paper sheets and the accumulated paper sheets are collected. A space can be secured between the sheets and the sheets can be prevented from interfering with each other. Further, after being accumulated in the accumulating portion, the deformation of the loop sheet member is released, so that the same operation as described above can be achieved and high reliability can be achieved when accumulating subsequent sheets.

Further, by arranging two or more loop sheet members on the outer side of the sandwiching / conveying means composed of the rollers forming the feeding portion, the above-mentioned operation can be made more reliable and a higher speed operation can be realized. it can.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings.

This figure shows an embodiment applied to a portion for accumulating statement slips for each transaction of an automatic cash handling apparatus.

In the side view of FIG. 1, the stacking unit 1 is composed of a base 11, a stopper 12 and an upper guide 13, on which the sheets 3 are stacked. The feeding unit 2 includes a conveyor belt 21,
Roller 22, loop sheet 23, conveyance guides 24, 25
The conveyor belt 21 is configured by a drive source (not shown).
Rotates in the direction of arrow A, and the roller 22 moves the conveyor belt 2
It is pressed against 1 and is driven to rotate in the direction of arrow B.

As shown in the top view of FIG. 2, in the feeding section 2, the conveyor belt 21 and the rollers 22 are arranged at two positions at a pitch of about ½ of the width of the statement slip 3, and the loop sheet 23 is
It is arranged on the outside.

As the loop sheet 23, a sheet made of polyimide resin and having a thickness of about 0.1 mm is formed in a loop shape as shown in FIG. 3, and is fixed to the conveyance guide 25.
The sheet 3 has a shape shown by a solid line before entering the feeding section 2, and after entering, it is deformed into a shape shown by a broken line. That is, during the stacking operation of the sheets, the reciprocating operation is performed as shown by the arrow C.

Next, the integration operation will be described with reference to FIGS.

In FIG. 4, when the leading edge of the sheet 3a conveyed along the conveying guide reaches the loop sheet 23a, the sheet 3a enters the feeding section 2 while deforming the loop sheet 23a.

As shown in FIG. 5, the entered sheet 3b deforms the loop sheet as shown in 23b, and the sheet 23b becomes
While receiving the reaction force of the elastic deformation of the loop sheet 23b and being pressed against the conveyor belt 21, the stacking unit 1
To enter.

As shown in FIG. 6, the leading edge of the sheet 3c is the stopper 1.
When it reaches 2, the trailing edge of the sheet 3c is released from the nip between the conveyor belt 21 and the roller 22, the reaction force of the loop sheet 23b is overcome, and the loop sheet 23b is restored to the state of 23a. To do. As a result, the trailing edge of the sheet 3c falls by its own weight and overlaps the accumulated sheets 3.

However, if the paper 3c is charged with a large amount of static electricity or if the paper 3c has a curl tendency, the trailing edge of the paper 3c cannot drop due to its own weight. Also in this case, as shown in FIG. 7, the succeeding sheet 3d deforms the loop sheet 23a, and as shown by 23c, the outer periphery of the loop sheet is the sheet 3.
The trailing edge of c is knocked off, and the stacked sheets 3 are reliably overlapped.

As described above, in the present embodiment, the loop sheet 23 strikes the trailing edge of the preceding paper every time the sheets are stacked one by one and lifts the entered paper to secure a space, It functions to send to the stacking unit and can stabilize the stacking operation. In order to maximize the effect of the loop seat, the seat length, rigidity,
It is necessary to optimize the layout etc. according to the size, thickness and rigidity of the paper.

Regarding the length and rigidity of the sheet, it is necessary that the sheet should not be folded or deformed and that the sheet may easily come off from the rear end of the sheet after being accumulated. In this embodiment, the sheet is formed of a polyimide resin having a thickness of about 0.1 mm in a loop shape. However, in order to optimize the rigidity, a plurality of sheets may be stacked or a loop shape may be formed as shown in FIG. You may add a short flat sheet inside the sheet.

Further, regarding the arrangement of the sheets, in the present embodiment, the sheets are arranged at two places on the outer side of the conveying belt of the feeding section, but the same effect can be expected at one place on the inner side of the conveying belt. Furthermore, instead of the conveyor belt of the feeding section,
As shown in FIG. 9, a roller and a guide may be used.

According to the present invention, by arranging the loop sheets, every time when the sheets are stacked one by one, the trailing edge of the preceding sheet is knocked off and the entered sheet is lifted to secure a space and stack the sheets. It functions to feed into the unit and can stabilize the stacking operation. In particular, it is effective when static electricity is charged or the paper has a crease or curl.

[0024]

According to the present invention, a loop sheet member is provided instead of a rotating member such as a rotating impeller of a conventional example, so that reliability of the stacking operation can be ensured at low cost. A compact, integrated mechanism can be provided.
