Abstract

PURPOSE:To prevent excessive pressing force applied to a bill by disposing a pressing plate with a constant-output spring adapted to operate when the weight of bills is more than a designated value in a storing box for repaying, collecting and drawing out bills in a storing apparatus of a reflux bill handling apparatus. CONSTITUTION:When the weight or thickness of bills 10 on a pressing plate 2 changes, the contact pressing force of the bill with a pick-up roller 8 produced by a spring 3 and a constant-output spring 4 is changed. At this time, when load exceeds a preset value, the constant-output spring 4 is operated so that the pressing plate 2 is moved in such a manner as to absorb a change in load. Thus, the pressing force applied to the bill is kept from exceeding a designated value by a simple and small-sized mechanism.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a paper sheet storage device, and more particularly to a recycling-type banknote handling device that handles deposited banknotes for reuse.

[Background of the invention]

As a conventional paper sheet feeding mechanism, for example, Japanese Patent Application Laid-Open No. 58-15
As described in No. 0855, the pressure applied to the feeding roller was controlled by a separate drive source.

As a result, the number of parts increased, and no consideration was given to costs, processing time, etc.

[Purpose of the invention]

The object of the present invention is to create a small paper sheet that has the following functions of collecting, returning, and feeding L paper sheets so that the pressure applied during feeding changes depending on the number of bills, that is, the weight, so that no more pressure than necessary is applied. The purpose of the present invention is to provide a type storage device.

[Summary of the invention]

The present invention improves maintainability, downsizes the device, and improves maintainability by using a removable storage box for paper sheets and collecting, returning, and dispensing paper sheets in one sheet storage device. It has a structure in which a push plate that applies pressure during feeding and a constant output spring that prevents excessive pressure is attached.

[Embodiments of the invention]

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a front sectional view of a paper sheet storage device according to an embodiment of the present invention, and FIG. 2 is a side view thereof.

The storage box 1 is removably installed on the main body of the t-device.

Inside, there are provided a push plate 2 that can be slid up and down by a slide shaft 5, a spring 3 that applies pressure to the push plate 2, and a constant output spring 4 that works when the push plate 2 reaches a required pressure or more. By moving the plate 2 up and down, necessary pressure is applied to the banknotes during feeding and stacking.

At the top of the storage box 1, there is a stack roller 6 that is driven when stacking banknotes, a stopper 7 that stops the conveyance of banknotes at the banknote stacking position, a pickup roller 8 that feeds out banknotes one by one from the stacked state, and a pickup. A feed roller 9 that conveys the banknotes fed out by the roller 8, and a gate roller 11 that prevents multiple feeding of banknotes 10 are arranged at a position facing the feed roller 9.

The pickup roller 8 is moved in and out of the bottom surface of the stack roller 6 by a drive source (not shown), and similarly
It is also configured to be moved up and down by a drive source to open and close a banknote conveyance path made up of feed rollers 9 and gate rollers 11.

A bushing 12 is provided inside the stack roller 6 and is driven up and down by a drive source.

The operation of the paper sheet storage device configured as described above will be briefly explained below.

FIG. 1 shows a state in which a storage box 1 containing banknotes 10 is set in the device.

As shown in FIG. 3, the banknotes 10 are fed out by means of a drive source (not shown) in which the pickup roller 8 is positioned on the lower surface of the stack roller 6. The push plate 2 can be attached to the spring 3 by removing the push plate stop device (not shown). Constant output spring 4
It rises and contacts the pick-up row 28 to apply pressure. The stopper 7 shown in FIG. 2 is retracted upward by a drive source (not shown), and by rotating the pick-up roller and feed roller 9 by the same drive source, the banknote 10 is first moved by the pick-up roller 8 to the feed roller 9 shown in FIG. and the gate roller 110, and then separated one by one by the feed roller 150 rotations and the gate roller 11 and fed out.

After all the banknotes have been fed out, the pickup roller 8 is raised and the feeding is completed.

The banknotes set on the push plate 2 have different weights depending on the type (bill size 2 paper thickness depending on the amount) and paper thicknesses depending on the degree of circulation of the banknotes (new banknotes or stiff thank you). .

Since the spring 3 has a constant spring constant (load per unit length), the load is proportional to the length of the spring, but the push plate 2
The weight of the banknotes set on top.

As the thickness changes, the load applied to the pickup roller 8K changes. There is a range of pressure applied by the pick-up roller 8 for feeding, and even if the pressure is small or large, it is not possible to reliably separate each bill one by one.As shown in Figure 4, the spring constant of the heaviest new bill If the spring characteristics of the spring S are such that the minimum necessary pressure is applied to the pickup roller, the circulation rate is high (one banknote is thick). When the banknotes are busy, the pressure applied to the pickup roller due to the spring 3 can be separated. It goes beyond the scope.

In order to prevent this, by providing a constant output spring 4 which operates when the load exceeds the set load at the lower end of the spring 3 and whose load does not change, the excess load applied to the pickup roller 8 is removed and the load is always separated from the pickup roller 8. Stable separation can be obtained by applying as much pressure as possible.

〔Effect of the invention〕

According to the present invention, a constant force spring is provided when paper sheets are fed out from a storage box removably installed in the device.
As a result, an inexpensive paper sheet storage device that prevents unnecessary pressing can be obtained.
