Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a paper sheet handling device, and in particular to a paper sheet handling device for handling rigid or folded paper sheets used in bank terminals, etc., one by one from a storage section. The present invention relates to a paper sheet handling device suitable for separating and processing deposits and withdrawals.

[Conventional technology]

In the conventional apparatus, as described in Japanese Patent Application Laid-Open No. 56-33758, sheets are separated one by one by a paper feeding section and sent to a discrimination section at the same speed as the processing speed of the apparatus.

In the conventional paper feeder, one rotation of the feed roller separates and feeds out one sheet of paper and sends it to a conveyance path at the same speed.

Generally, the design specifications such as the diameter of the F roller and the rotation speed are determined so that the interval between the sheets of paper that is intermittently sent to the conveyance path is every other sheet, that is, the interval is the same as the width of the sheet of paper. be done.

[Problem that the invention seeks to solve]

In the prior art, when paper defects with poor conditions such as folds, wrinkles, and tears are separated at a high speed, not only does it cause skew and periodic disturbances, but it also damages the paper defects. In addition, since the separation is carried out at the same speed as the processing speed of the equipment, the condition during separation becomes unstable (excessive skew or shift occurs), making it impossible to identify the rejects. The problem was that the rate increased.

The purpose of this application is to
It also reduces the rejection rate and reduces load.

The objective is to provide a highly reliable paper sheet handling device.

[Means for solving problems]

In order to achieve the above object, the present invention provides a means for feeding out accumulated paper sheets, and a means for separating and feeding the fed out paper sheets one by one at a speed lower than a planned paper sheet processing speed. means, means for straightening wrinkles etc. of the fed paper sheets, and increasing the processing speed of the separated paper sheets to a predetermined processing speed,
It is equipped with means for increasing the speed of conveyance and means for accumulating the conveyed paper sheets.

[Function] According to the above configuration, the separation feeding speed is set to be low, for example, 1/2 or 1/4 of the conventional speed, and one of the F rollers of the feeding means is
By separating and feeding out two sheets by rotation, it is possible to feed out the sheets stably without causing skew or shift, even under poor paper conditions. In addition, by passing the paper through the correcting means at a low speed, the effect of correcting folds, wrinkles, etc. is increased and the rejection rate is reduced. Since the skew is corrected as necessary and sent to the discrimination section, processing can be performed at the same speed as before.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a recycling type cash handling device 1 of an automatic teller machine that handles paper waste as one sheet. In the figure, the cash handling device 1 is equipped with a deposit/withdrawal port 3 on the front side of the main body 2, and on one side of the deposit/withdrawal port 3 there is a separation section 20 for taking in the deposit paper M, and on the other side there is a separating section 20 for taking in the deposit paper M. There is a dispensing paper
At the center of the main body 2, where an extrusion fork 4 for pushing the paper out to the deposit/withdrawal port 3 is provided, there is provided a discrimination section 5 for determining the authenticity of the paper M to be taken in or dispensed.

A pick box 6 is provided at the rear central portion of the main body to collect paper waste M that cannot be identified.

Above the reject box 6, that is, at the rear upper part of the main body, a front-back reversing unit 7 for reversing the reverse paper M to face up is arranged. An impeller stacker section 8 is provided at the extrusion fork 4 described above. From the center to the bottom of the main body, from the rear to the front of the main body, there is a first denomination box 9A for recycling paper waste, and a second denomination box 9M for recycling paper waste, at the beginning of work or at the end of work. At the same time, there is a safe 11 for supplying paper M and collecting paper M that is inappropriate for withdrawal, a temporary stacker section 12 for temporarily storing the taken-in paper M, and a temporary stacker section 12 below the temporary stacker section 12 for collecting forgotten paper M. A box 13 is arranged. First and second denomination boxes 9A.

9M, each upper part of the safe 11 and the temporary stacker part 12 has an impeller stacker part 141, a separation mechanism 15, and a feeding mechanism 1.
6 is placed. The above-mentioned parts are connected by a conveyance means, and a gate part is provided at a branch part in the conveyance means. Further, a slip/card mechanism 1 passbook printing mechanism is installed above the cash handling device.

The cash handling device temporarily stores the paper M inserted into the deposit/withdrawal port 3 by the customer in a temporary stacker section 12, and then stores it in denomination boxes 9A, 9M and money W, 11 according to denomination.

In addition, according to a customer's request, the paper M stored in each denomination box can be dispensed to the deposit/withdrawal port 3 through the front-back reversing section 7 with the front surfaces aligned.

Between the deposit/withdrawal port 3 and the discrimination section 5, there is a
Separation part 20, correction part 30 such as Shib. A speed-increasing conveyance section 40, a conveyance section 50, and a skew correction section 6o are arranged in this order,
A paper defect detection sensor 70 is provided on the upstream side of the conveyance section 50.

The separation section 20 is composed of a pickup roller 2o1 (hereinafter referred to as P roller), a feed roller 202 (hereinafter referred to as F roller), and a gate roller 203 (hereinafter referred to as G roller).

The sheets of paper M are stacked on a press plate 204 and are pressed against the P roller 201 by a spring 205 from below the press plate.

In the separation section 20, the paper sheets M are separated one by one by the contact between the F roller 202 and the G roller 203 or the resistance force of the overlapping portion, and are conveyed to the next wrinkle correction section 30.

Note that when the P roller 201 and the F roller 202 are driven independently, it is necessary to synchronize their speeds. Further, the interval between the separated filter papers is determined, for example, by the intermittent drive ratio (stop/rotation) of the P roller 201. If this intermittent drive ratio is appropriately selected, it is possible to send out the paper with a gap of almost zero, as shown in the section 4 of FIGS. 4(a) and 4(b).

As shown in FIG. 3, the wrinkle correction unit 30 includes, for example, a heat roller 301 and a roller 302 that is in contact with the heat roller 301.
There are power feeding brushes 303 on both ends of this roller.
A, 303M is provided.

The speed-increasing conveyance section 4o is composed of a roller 401 with a built-in one-way clutch and a roller 402 that is in contact with this roller and can rotate idly.

In the speed-increasing conveyance section, the waste paper that is separated in the separating section 20 at a speed v1 lower than the planned paper waste processing speed is increased to the planned processing speed v2 of the apparatus. That is, from the moment the leading edge of the paper passes through the speed-increasing conveyance unit 40 and reaches the conveyance unit 50, the paper is accelerated from V to v2.

Further, the conveying section 50 has sending rollers 501A and 501M, and a conveying belt 502 is provided on the lower roller of each roller.

The skew correction roller 60 is disposed midway through the conveyance of the conveyance section 50, and is accelerated or decelerated by drive sources (not shown) provided independently on the left and right sides.

In addition, in the present invention, the separation feeding section and the conveyance roller 501,
A speed-increasing conveyance unit can be constructed by disposing a roller having a lower paper-gripping force than the conveyance roller 501A in the middle of the conveyance roller 501A. This roller receives paper damage from the separating and feeding section, and the conveying section 5
When the leading edge of the paper is pinched by the conveying rollers, the leading edge of the paper slips at this side and is pulled by the conveying rollers 501A, accelerated, and sent out. Note that similar results can be obtained using a roller with a built-in one-way clutch.

Next, an explanation will be given assuming that the processing speed of the apparatus is V, (for example, 10 sheets/sec), and the paper separation speed is V,=1/2V.

The conveyance path 80a connecting the separating section 20 of the deposit/withdrawal port 2 to the speed-increasing conveyance section 40 and the temporary stacker section 12 and the heat roller 301 of the wrinkle correction section 30 is always driven at a speed of vl. Similarly, the first and second denomination boxes 9A and 9M
, the separating mechanism 15 and the feeding mechanism 16 of the safe 11 and the temporary stacker section 12, and the transport path 16a of the safe 11 and temporary stacker section 12.
is also always driven at a speed of vl. The conveyance path 80 disposed on the denomination boxes 9A, 9M, the safe 11, and the temporary stacker section 12 can be driven independently of other conveyance paths, and the speed is v2 in the deposit mode and the speed of v2 in the withdrawal mode. is driven by switching between two speeds. Note that conveyance paths other than those described above are always driven at v2.

From the relationship that the paper width M from the separation unit 20 is V, = 1/2V, the paper is conveyed to the speed-up conveyance unit 40 in the state shown in section A in FIG. be done. Low speed V
As a result of passing through the heat roller 301 during the process, folds and wrinkles in the paper are corrected. From the moment the leading edge of the paper edge reaches the delivery roller 501A of the conveyance section 50, it is accelerated from V to V2, and on the conveyor belt 502, the width is the same as the paper edge width Q, as shown in section B in FIG. 4(a). The interval will be .

When the paper that has been accelerated to a speed of v2 reaches the detection sensor 70, the amount of skew is measured, and if the amount of skew is determined to be excessive, a control device (not shown) causes the skew correction roller to adjust the amount of skew. Acceleration/deceleration is performed to bring the value to zero. As a result, Figure 4 (a
) can be obtained. Thereafter, the paper passes through the discrimination section 5 and the conveyance path 80 to the temporary stacker section 1.
It is stored in 2.

Temporary stacker separation and feeding mechanism 15°16 to v
The paper waste separated at a speed of o is conveyed via the separation conveyance path 16a and the conveyance path 80a to the speed increasing conveyance unit 40 in the state shown in section A in FIG. The denominations are sent to the department 5 and stored in the denomination boxes 9A, 9M or the safe 11 according to the discrimination results.

On the other hand, in the dispensing mode, the conveyance path 80 is switched to the speed V□ in advance, and the paper waste that has been separated from each denomination box at the speed v1 and conveyed to the accelerated conveyance unit 40 is accelerated to v2, and the The amount of skew is corrected and the money is withdrawn to the deposit/withdrawal port 3 via the discrimination section 5.

According to this embodiment, since the conveyance belt 502 of the conveyance section 50 is disposed only below the delivery rollers 501A and 502B, unnecessary resistance is not generated when correcting the skew amount of one sheet.

In this embodiment, the case of frictional separation has been described, but a vacuum type or other separation means can also be applied.

In addition, in this embodiment, v1 = 1/2 V, but if the sheets are fed out by overlapping each other by half the paper width during one-minute feeding, the P roller should be rotated continuously, and the rotational speed of the P roller and F roller should be changed to the conventional speed. If the speed is set to 174, that is, ■□=1/4V2, the paper spacing on the conveyance path will be the same as the conventional one. (Refer to FIG. 4(b)) In addition, in this embodiment, a one-way clutch is built into the roller 401 of the speed-increasing conveyance section 40, but a material with a lower coefficient of friction than the other rollers may be used, or the lower roller 402 may be It may be pressed against the roller 401 by spring force. Alternatively, instead of a pressure roller, the rigidity of one sheet of paper may be used to convey it with an overlap roller, so that the sheet of paper reaches the delivery roller 5o and is easily slipped when accelerating from ■1 to v2. .

Furthermore, although this embodiment has been described with respect to a paper sheet handling device applied to a recycle-type deposit/withdrawal device, it is applicable to general devices such as automatic teller machines.

〔Effect of the invention〕

According to the present invention, it is possible to perform separation at low speed without reducing the processing speed of the device, prevent damage to paper sheets during separation, and obtain stable separation performance, resulting in high performance and We can provide highly reliable equipment.

In addition, the power required for separation can be kept low, and furthermore, the diameter of the feed roller can be made smaller, thereby making it possible to downsize the device, making it possible to provide a small, low-load device.
