Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper sheet take-out device used for taking out paper sheets such as paper money stored in a paper money storage (stacker) of a paper money processing apparatus used in, for example, a ticket issuing machine.

[0002]

2. Description of the Related Art For example, a bill processing device used in a ticket issuing machine or the like incorporates a bill taking-out device that takes out a bill from a stacker containing the bill when the bill is taken out as a fishing tag.

As such a bill take-out device, for example, a roller provided below the stacker is brought into contact with the surface of the bill located at the lowermost stage of the stacker, and the bill placed at the lowermost stage is rotated by the rotational force of the roller. There is something to take out from the stacker. In such a bill ejecting device, in order to reliably eject the bill, it is desirable that the pressing force generated between the lowermost bill and the roller is constant.

However, in the conventional paper money take-out device, the pressing force generated between the paper money and the roller at the lowermost stage fluctuates depending on the number of paper moneys stored in the stacker, so that the paper money cannot be taken out accurately. There is a problem.

As a bill taking-out device that solves such a problem, there is a bill taking-out device 1 shown in FIG. 9, for example. In the banknote take-out device 1 shown in FIG. 9, the press plate 8 and the floor guide 9 are arranged so that the banknotes 2 are stored in a state of being inclined at a predetermined angle from the vertical direction. By doing so, fluctuations in the pressing force between the lowermost banknote and the feeding roller 3 due to the increase or decrease of the stored banknotes 2 are reduced. An elastic force P by a spring or the like is applied to the press plate 8 toward the floor guide 9.

A take-in roller 4 and a gate roller 7 are provided on the output side of the bill with respect to the feed-in roller 3, and transport pinch rollers 5 and 6 are provided on the output side. Feed roller 3 and take-in roller 4
Is a grooved rubber tip 3a, 4a with high friction on a part of the outer circumference.
Is built in, and the banknotes located at the bottom are sent discontinuously toward the transport pinch rollers 5 and 6.

The gate roller 7 prevents the plurality of banknotes from being superposed and simultaneously sent out by applying an elastic force p by a spring or the like to the sent out banknotes.

[0008]

However, in the above-described bill take-out device 1 shown in FIG. 9, the elastic force P due to the spring or the like works small when the number of bills 2 to be stored is small, and works large when it is large. . Therefore, even if the storage space for the banknotes 2 is tilted to reduce the influence of the own weight of the banknotes 2 due to the increase or decrease of the banknotes 2 stored therein, it is not possible to apply a certain pressing force to the bottommost banknotes, and the banknotes are accurately There was a case that it could not be taken out.

Further, the bill take-out device 1 shown in FIG. 9 has a problem that the device becomes large in size because the storage space for the bills 2 is inclined.

The present invention has been made in view of the above-mentioned problems of the prior art, and an object of the present invention is to provide a paper sheet take-out apparatus which can take out paper sheets such as banknotes accurately with a small-scale apparatus.

[0011]

In order to solve the above-mentioned problems of the prior art and achieve the above-mentioned object, the paper sheet take-out device of the present invention is mounted on the uppermost stage of a plurality of stored paper sheets. The pressing means that presses the paper sheet that is placed and stored by its own weight toward the pushing roller, and increases in proportion to the rising of the pressing means in the direction of raising the pressing means with respect to the pressing means. And a pressing force adjusting means for applying an elastic force so that the pressing force between the lowermost sheet and the delivery roller becomes substantially constant.

Further, in the paper sheet take-out device of the present invention, preferably, the pressing force adjusting means includes a first pulley around which the other end side of a linear body having one end fixed to the pressing means is wound, and the first pulley. A first gear that rotates in the same direction in conjunction with the first pulley, a second gear that rotates in the opposite direction to the first gear while meshing with the first gear, and the pressing means are raised. The second pulley has a second pulley that is wound around the other end of a linear body whose one end is fixed via an elastic member that generates an elastic force in the direction of rotation, and that rotates in the same direction in conjunction with the second gear.

[0013]

In the paper sheet take-out device of the present invention, the pressing force between the paper sheet and the roller located at the bottom is calculated from the total weight of the banknotes stored in the paper sheet storage section and the total weight of the pressing means. The value is the value obtained by subtracting the elastic force applied by the pressing force adjusting means.

When the number of banknotes stored in the paper sheet storage section decreases, the pressing means descends, and the elastic force applied by the pressing force adjusting means decreases in accordance with this decrease. At this time, if the amount of change in the elastic force with respect to the amount of movement of the pressing means is appropriately set, the amount of reduction in the total weight of the banknotes due to the decrease in the number of banknotes stored in the paper storage unit and the pressing due to the lowering of the pressing means. The amount of reduction of the elastic force applied by the means can be matched. As a result, the pressing force between the roller and the paper sheet located at the bottom can be kept constant.

On the other hand, if the amount of change in the elastic force with respect to the amount of movement of the pressing means is set appropriately in this way, even when the number of banknotes stored in the paper sheet storage section increases, the bottommost stage will also become the same. It is possible to keep the pressing force between the paper sheet and the roller positioned at the constant.
