DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

2. Description of the Related Art A highly reliable sheet stacking mechanism including a stacking section for stacking and stacking sheets conveyed one by one and a feeding section for sending the sheets to the stacking section has high reliability. To secure, the leading edge of the paper sent to the stacking unit
It is necessary that the rear end of the paper sheet does not interfere with the front end of the following paper sheet without interfering with the stacked paper sheets. This needs to be considered especially when handling paper sheets having a kinks or curls, or when static electricity is likely to be generated due to high-speed handling, and various realizing methods have been devised.

As an example, there is Japanese Utility Model Publication No. 5-12209. According to this, a rotating impeller is arranged in the feeding section, and the rear end of the fed sheets is knocked down, thereby preventing interference with subsequent sheets.

[0004]

In the above-mentioned conventional example, a high-reliability is realized by disposing a rotating impeller in the feeding portion. However, the impeller and its driving source are required, and cost is reduced. There was a problem. In addition, a mounting space for the rotating impeller is required, which limits the size of the mechanism.

An object of the present invention is to provide a paper sheet stacking mechanism capable of realizing high reliability without arranging a member such as the rotating impeller of the conventional example.

[0006]

In order to achieve the above-mentioned object, in order to achieve the above object, a stacking section for stacking and stacking sheets conveyed one by one and a feeding section for sending the sheets to the stacking section are provided. In the paper sheet stacking mechanism, a loop sheet member in which an elastic sheet is formed into a loop is disposed in the feeding section, and when the paper sheets are sent to the stacking section, the loop sheet member is moved by the paper sheet. A part of the loop-shaped outer periphery of the loop sheet member comes into contact with the deformed and accumulated paper sheets, and the paper sheets sent out along another part of the outer periphery are guided and accumulated in the accumulation unit. The configuration is such 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 / transporting means comprising rollers forming a feeding portion.

As described above, the paper sheet sent from the feeding section to the stacking section deforms the loop sheet member, and a part of the loop-shaped outer periphery of the loop sheet member contacts the stacked sheet sheet. As a result, the rear end of the accumulated paper sheets is reliably knocked down, and the transmitted paper sheets are guided along the other part of the outer periphery, so that the transmitted paper sheets and the accumulated paper sheets are guided. A space can be secured between the papers, and interference between paper sheets can be prevented. Further, after being stacked in the stacking unit, the deformation of the loop sheet member is released, so that when stacking subsequent sheets, the same operation as described above is achieved, and high reliability can be realized.

Further, by arranging two or more loop sheet members outside the nipping / transporting means comprising rollers forming a feeding portion, the above-mentioned operation is further ensured and a higher speed operation is realized. it can.

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

FIG. 1 shows an embodiment in which the present invention is applied to a portion of an automatic cash handling apparatus which accumulates statement sheets for each transaction.

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

As shown in the top view of FIG. 2, the feeding section 2 arranges the conveying belt 21 and the rollers 22 at two places at a pitch of about の of the width of the statement sheet 3, and the loop sheet 23
It is arranged outside this.

As shown in FIG. 3, the loop sheet 23 is formed from a polyimide resin sheet having a thickness of about 0.1 mm in a loop shape and fixed to the transport guide 25.
Before the paper 3 enters the feeding unit 2, the paper 3 has a shape shown by a solid line, and after the paper 3 enters, the paper 3 is deformed into a shape shown by a broken line. That is, during the sheet stacking operation, the sheet reciprocates as indicated by arrow C.

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

In FIG. 4, when the leading end 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 by 23b, and the sheet 23b is
The stacking unit 1 receives the reaction force of the elastic deformation of the loop sheet 23b and keeps being pressed against the transport belt 21.
To enter.

As shown in FIG. 6, the leading end of the sheet 3c is
2, the trailing end of the sheet 3c disengages the conveyor belt 21 and the roller 22, and the reaction force of the loop sheet 23b wins, and the loop sheet 23b recovers to the state of 23a. I do. As a result, the trailing end of the sheet 3c falls due to its own weight, and overlaps the stacked sheets 3.

However, if the paper 3c is charged with a large amount of static electricity or has a curl habit, the trailing end of the paper 3c cannot fall due to its own weight. Also in this case, as shown in FIG. 7, the subsequent sheet 3d deforms the loop sheet 23a, and the outer periphery of the loop sheet
The rear end of the sheet c is knocked down, and the sheet 3 is surely overlapped with the stacked sheets 3.

As described above, in this embodiment, each time the sheets are stacked one by one, the loop sheet 23 knocks down the rear end of the preceding sheet, and secures a space while lifting the entered sheet. It functions to feed into the stacking section and can stabilize the stacking operation. In order to maximize the effect of the loop sheet, the length, rigidity,
It is necessary to optimize the arrangement and the like according to the size, thickness, and rigidity of the paper.

The length and rigidity of the sheet need to be such that the sheet does not bend or deform, and that the sheet is easily pulled out from the trailing edge after being accumulated. In the present embodiment, a polyimide resin having a thickness of about 0.1 mm is formed in a loop shape on the sheet. However, in order to optimize the rigidity, a plurality of sheets are stacked or a loop shape is formed as shown in FIG. A short flat sheet may be added inside the sheet.

In this embodiment, the sheets are arranged at two places outside the conveying belt of the feeding section, but the same effect can be expected at one place inside the conveying belt. Furthermore, instead of the transport 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 sheet, every time sheets are stacked one by one, the trailing edge of the preceding sheet is knocked down, the space is secured while lifting the entered sheet, and the stacking is performed. It functions to feed into the unit and can stabilize the integration operation. In particular, this is effective when the static electricity is charged or the paper has a bending or curling habit.

[0024]

According to the present invention, by arranging a loop sheet member instead of the conventional rotating member such as a rotating impeller, the reliability of the integration operation is ensured, and the cost is reduced. A compact, integrated mechanism can be provided.
