Abstract

PURPOSE:To simply compensate the skew of papers, by providing a deformable ring belt which is associated with a conveyor roller for papers so that the belt is made into slidable contact with a paper, thereby the lower end of the paper is pushed up by means of the ring belt to make the top end of the paper in contact with a see-saw type lever. CONSTITUTION:Upon transfer of a paper 33 from a conveying path A to a conveying path B by way of a temporary pool 21, the paper 33 is pressed against a paper conveyor roller 22 by means of a pinch roller 21 so that the paper is conveyed into a temporary pool 21 due to rotation of the conveyor roller 22. When the trailing end of the paper leaves away from the roller 22, the front end of the paper 33 is transferred by a ring belt 25, and therefore, is abutted against a see- saw type lever 28. At this time if the paper 33 is skewed, the ring belt 25 is deformed so that the skewed side of the paper 33 is pushed up together with the see-saw type lever 28, overcoming a spring 30. Accordingly, the skew of the paper 33 is compensated, and is then transferred into the conveying path B.

Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field of the Invention The present invention relates to a sheet oblique J' mechanism in a sheet handling device.

BACKGROUND ART AND PROBLEMS Below, a recycler withdrawal device used in banks will be described as an example of a paper sheet handling device. This device has a structure as shown in FIG. 1. Bills inserted from a bill deposit/withdrawal port 1 are sent one by one to a conveyance path 2, and a primary discrimination section 3 distinguishes the denomination and front and back sides. Based on the data, the unfit notes are aligned in one direction in the front and back alignment unit 4 and pooled, and then discriminated again in the secondary discrimination unit 5, and based on that data, the unfit notes are sent to the unfit note storage box 6, 10,000 yen, 5,000 yen. The banknotes of yen and thousand yen are stored in respective storage boxes 7, 8.9. In addition, for withdrawal, the required number of bills are taken out from each bill storage box and passed through the conveyance path 10.
After being sent to the secondary discrimination section 5 and discriminated, one banknote is transferred to the withdrawal port 1.
It is temporarily pooled before 0 and sent to deposit/withdrawal port 1 all at once.

When banknotes are transported in such a device.

If the bill is conveyed obliquely, the determined position of one bill cannot be read out during discrimination in the discrimination section.

Also, there is a problem that the items are not aligned when they are temporarily pooled or stored in a storage box.

As a countermeasure to this problem, a tilt correction mechanism as shown in FIG. 2 can be considered. In the figure, 11 is a banknote.

12 is a conveyance path, which is a conveyance path between the deposit/withdrawal port 1 and the discrimination section 3 shown in FIG. 13 is a feed roller; 14.
15 are oblique correction rollers provided on the left and right sides of the conveyance path;
4' and 15' are the drive motors.

1 and 2 are sensors provided on the left and right sides of the conveyance path, and 16 is a control circuit. The function of this mechanism is that when the banknotes 11 being conveyed in the direction of the arrow are running diagonally, the control circuit 16 calculates the speed of the rows 214 and 15 based on the time difference between detecting the banknotes with the sensor. I am trying to correct the skew by changing it.

However, such a mechanism has the disadvantage that it requires a control circuit, a circuit for adjusting the start-up time of the drive motor, and the like, making the structure complicated.

OBJECTS OF THE INVENTION In view of the above-mentioned conventional drawbacks, it is an object of the present invention to provide a paper sheet skew correction mechanism with a simple structure.

According to the present invention, the present invention provides a sheet transport path having a branch path that branches into two directions from a temporary pool portion, and a paper sheet transport path that is located approximately in the center of the branch path and that is located in the transport direction of the transport path. It is driven by a plurality of paper sheet conveying rollers attached to one drive shaft provided at right angles, and a small diameter roller attached to the drive shaft, and has a diameter smaller than that of the paper sheet conveying roller. Consisting of a plurality of large ring belts and a seesaw-shaped lever that is swingably supported on a shaft that is located at the center of the end of the temporary pool part and is biased in the direction of the branching path. This is achieved by providing a paper sheet skew correction mechanism characterized by the following.

Examples of the invention Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 3 is a diagram for explaining the paper sheet skew correction mechanism according to the present invention, in which a shows a front view and b shows a sectional view taken along line bb in FIG. In the same figure.

20 is a paper sheet conveyance path, 21 is a temporary pool portion that occupies a part thereof, A and B are branch paths, 22 is a paper sheet conveyance roller, 2
3. 23' is the pinch roller, 24 is the drive shaft, 25 is the ring belt, 26 is the ring belt drive roller, 27 is the ring belt holding row 2, 28 is the seesaw type lever, 2
9 is its support axis.

30 represents a spring, and 31 represents a stopper.

In this embodiment, as shown in FIG. 3, a paper sheet transport path 20 is constituted by a temporary pool section 21 in which all sheets are temporarily pooled, and branch paths A and B that are divided into two directions from the temporary pool section. One drive shaft 24 is provided approximately in the center of branch paths A and B,
The drive shaft 24 is provided with a plurality of sheet conveyance rollers 22 and a plurality of ring belt drive rollers 26 , and a ring belt 25 is held between the rollers 26 and a ring belt holding roller 27 . Further, at the end of the temporary pool part 2, a seesaw-shaped lever 28 is swingably provided on a shaft supported by a pin 32 and biased in the direction of arrow P by a spring 30.

The ring belt 25 is made of an elastic material such as rubber and is formed into a ring shape with an outer diameter larger than that of the paper sheet transport roller 22, but when transporting one sheet, it is easily deformed by the sheet. It has become.

The operation of this embodiment configured in this way is illustrated in FIGS. 4 to 6.
This will be explained using figures. In each figure, a is a front view, b is a
A sectional view taken along the line bb in the figure, and C shows a sectional view taken along the line CC in the figure a. In addition, the same parts as in FIG. 3 are indicated with the same reference numerals.

To explain with reference to the drawings, first, as shown in FIG. 4, the banknotes 33 conveyed from the conveyance path A are pressed against the paper sheet conveyance roller 22 by the pinch roller 23, and conveyed toward the temporary pool section 21 by the rotation thereof. In this embodiment, the conveyance path A is connected to the conveyance path through which banknotes are sent from the banknote deposit/withdrawal port 1. Further, the conveyance path B forms a conveyance path toward the insertion port of the primary discrimination section 3. When the rear end of the banknote 33 leaves the paper sheet conveying roller 22, the front end of the banknote fed by the ring belt 25 is drawn onto the 7-piece lever 28. At this time, if the banknote 33 is slanted, the ring belt 25 will deform as shown in Figures b and c (W. Especially on the side where the banknote is delayed (Figure 0)
The deformation of is thick. Therefore, the trailing side of the bill 33 is pushed up by the ring belt 25 and becomes straight as shown in FIG. At this time, the seesaw-shaped lever 28 is pushed up against the spring 30 from the normal position shown by the dotted line.

When the ring belt 25 further rotates, the straightened bill 33 is pressed downward by the spring 30 as shown in FIG. It passes through branch path B and is sent to the next conveying means.

According to this embodiment, since the oblique orientation of the banknote is corrected as described above, by providing this mechanism at the front stage of the discrimination section 3.5, the data can be kept constant when discrimination is performed in the primary conveyance system. , high-speed processing is possible.

Moreover, the structure is simple and the cost is low.

As described above, the paper sheet skew correction mechanism of the present invention can correct the paper sheet skew with a simple structure by using a deformable ring belt as the paper sheet feed roller. It is very effective.
