Abstract

PURPOSE:To prevent paper leaves or the like liable to be folded from bucking and oblique movement when they are separated and sent out, by constituting a frictional portion of a drawing-out means of a first member having a vibration absorbing means for determining the deforming property of the frictional portion and a second member constituting the outside surface of the first member. CONSTITUTION:A frictional member 101 of a drawing-out means 1 successively pivots to send out paper leaves 12 or the like. Then, the frictional member 101 is provided on the inside a hollow part so that the drawing-out means 1 does not provide a vibration giving source for the paper leaves 12 even if the frictional member 101 projects from a roller boss 104, and a frictional member 102 deforms toward the inside to have a vibration absorbing action. Since the frictional member 101 is provided on the outside with a groove 105 having a tooth bottom, so that the member 102 is formed into an irregular tooth shape. Thus, when the member 102 is deformed more than a certain value, adjacent tooth-shaped members 102 abut against each other to increase the deforming resistance.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a paper sheet separation device, and is particularly used in recirculating automatic teller machines, automatic teller machines, etc., for handling weak banknotes and various types of paper sheets that are easily folded. The present invention relates to a paper sheet separation device suitable for separating and sending out a large number of banknotes in the following state.

[Conventional technology]

As a conventional separation device of this kind, for example, Japanese Patent Application Laid-Open No. 63-2
As disclosed in Japanese Patent No. 12628, there is an attempt to stabilize the pressing force against the paper sheets by using a deformable structure for a feeding means called a paper sheet feeding roller.

[Problem to be solved by the invention]

In the above-mentioned conventional technology, the feeding means called the feed roller for paper sheets has a deformable structure, so the pressing force against the paper sheets is relatively stable, but it still fluctuates considerably, especially for weak banknotes and folded paper sheets. When a large number of banknotes in various states are piled up, stable separation and delivery cannot be performed, resulting in buckling or jamming.

The present invention has been made in view of the above points, and its purpose is to provide paper sheets that can be stably separated and sent out over a long period of time without being affected by accumulated paper sheets. The purpose of the present invention is to provide a separation device.

[Means to solve the problem]

In order to achieve the above object, there is provided a paper sheet separation device that feeds paper sheets fed out by a friction member of a feeding means to a separating section and separates the paper sheets.

The friction member of the feeding means includes a first member having a vibration absorbing means that determines its deformation characteristics, and a second member forming an outer surface of the first member.
The friction member of the feeding means has an uneven outer surface, and as a vibration absorbing means for the first member that determines the deformation characteristics, the friction member of the feeding means has a hollow part or foam that allows the first member to deform. The structure is made of a flexible member, an anisotropic member, a multilayer structure member, etc., and even if the second member of the feeding means wears out, the first
The structure shall be such that it does not affect the deformation characteristics of the members,
The feeding means is provided with a means for preventing the paper sheets from being skewed when the paper sheets are fed out, and as the means, the feeding force of the paper sheets by the feeding means is distributed in the axial direction of the feeding means. The feeding means is configured to have a larger feeding force on the center side of the paper sheets to be separated than on both outer sides.

[Effect]

In the present invention, the friction member of the feeding means is.

a first member having vibration absorbing means that determines its deformation characteristics;
and a second member constituting the outer surface thereof, and has a structure having vibration absorption means such as a hollow part that allows deformation of the first member, or a foamed member, an anisotropic member, a multilayered member, etc. The structure is such that even if the second member wears out, it does not affect the deformation characteristics of the first member, so it can be used for bills that have a non-circular shape, are weak, or are bent. When a large number of banknotes are piled up, even if the above-mentioned external factors try to act as a vibration source on the feeding means and the paper sheets during the separating and feeding operation of the paper sheets, the first member has a vibration absorbing means. Since a stable pressing force can be applied to the paper sheets, there is no buckling or jamming of the paper sheets.

In addition, with respect to the force of feeding out paper sheets by the feeding means,
Since the feeding means is configured to have a distribution in the axial direction and to have a larger feeding force on the center side of the paper sheets to be separated than on both outer sides, it is possible to handle paper sheets in various states with creases. If a large number of sheets of the same type are piled up,
Even when the paper sheets to be separated and sent out have an uneven shape, it is possible to prevent the paper sheets from being skewed when they are separated and sent out.

〔Example〕

Embodiments of the present invention will be described below with reference to FIGS. 1 to 19. Fig. 1 shows an example of the configuration of a paper sheet separation device, in which 1 is a feeding means, 2 is a feeding roller which is a separating means, and 3 is a resistance roller which is a separating means, and the pair 2.3 constitutes a separating means. It is something to do. The feeding means 1 has a first friction member 101 arranged on a part of its outer periphery, a friction member 201 is arranged on a part of the outer periphery of the feeding roller 2, and a friction member 101 is arranged on a part of the outer periphery of the resistance roller 3. 301 is installed. The outer surface of the friction member 101 has an uneven second surface.
The member 102 has a hollow portion 103 inside. 4 is the shaft of the feeding roller 1, 5 is the feeding roller 2
, 6 is a toothed pulley attached to shaft 4, 7 is a toothed pulley attached to shaft 5, 8 is a toothed belt, 9 is a shaft 4, 5
One end of the bracket on the shaft 4 side is extended and attached to a spring 11 attached to the frame 10.

The spring 11 urges the feed roller 1 in the direction of the sheet 12.

A sensor 13 is provided at a position on the shaft 4 side of the bracket 9 to detect the vertical position of the feeding roller 1. A light shielding plate 15 of the sensor 14 is provided at one end of the shaft 5, and when the feeding roller 1 and feeding roller 2 are rotated synchronously by the toothed belt 8, the portion of the feeding roller 1 without the friction member 101, that is, the feeding roller boss. 104 rotational phases can be detected.

16 is a push plate, and motor 17. It can be driven up and down via a belt 18 and a slide rail 19, and 20 is a push plate control section.

The operation of the paper sheet separating device configured as above will be explained below.6 The feeding means 1 and the feeding roller 2 are rotated in the direction of the arrow by a separation motor (not shown), and the friction member 1
01 comes into contact with the uppermost paper sheet 12 among the paper sheets piled up on the push plate 16, the paper sheet 12 is sent out to the left in this figure, and Roller 2. They are separated and conveyed by resistance rollers 3.

The push plate control unit 20 detects when the sensor 14 detects that the peripheral surface of the feeding roller boss 104 of the feeding means 1 is in contact with the sheet 12, and detects that the position of the feeding means 1 is low. 13 detects this, and therefore, when the pressing force of the feeding means 1 on the paper sheet 12 is lower than the reference value, the motor 17 is driven, the push plate 16 is raised, and the paper sheet 12 is
It operates to apply an appropriate pressing force to the

Thereafter, the friction member 101 of the feeding means 1 is moved as shown in FIG.
As shown in FIG. 4, the paper sheets 12 are sent out by sequential movement. At this time, the friction member 101 feeds out the roller boss 104
Even if it protrudes further, a hollow part 103 is provided inside the friction member 101 so that the feeding means 1 does not become a source of vibration to the paper sheets 12, and as shown in FIG. By deforming inward, it has a vibration absorption effect.

The conventional example of the feeding means shown in FIG. 20 also has a hollow part 103 inside the friction member 101, so it has a similar vibration absorbing effect, but as shown in the figure, the friction member 1
The frictional force between the friction member 101 and the paper sheet 12 is large at the front end (a) and rear end (c) of 01, and is small at (b). This means that the pressing force against the paper sheet 12 is large at the front and rear ends of the friction member, and small at the center, which is not preferable from the standpoint of wear. That is, since wear generally progresses in proportion to the pressing force of the contact portion, the front and rear ends of the friction member wear out first. At this time, the shape and deformation state of the friction member 101 change, which adversely affects the separation and conveyance operation of paper sheets. Further, the fact that the pressing force at the center of the friction member 101 is low means that the friction member has a low deformation resistance force, and therefore is forced to undergo large deformation. Therefore, the elongation rate of the friction member becomes high, causing problems such as cutting.

As shown in FIG. 5, the outer shape of the friction member 101 of the present invention is such that one member 102 has an uneven tooth shape by providing a groove 105 with a tooth bottom. When deformed, adjacent tooth-shaped members 102 come into contact with each other, as shown in FIG.
Deformation resistance increases. Therefore, 1 paper sheet 1
The pressing force against the friction member 101 is uniform at the front end, center, and rear end of the friction member 101, and does not adversely affect the separating and conveying operation of paper sheets.

FIG. 7 shows another embodiment of the groove 105, and FIG.
This is an explanatory diagram when the member 102 shown in the figure is deformed to a certain value or more, and has the same effects and actions as FIG. 6.

FIG. 9 is a diagram showing an embodiment of the feeding means 1 in FIG. 1. Here, a case is shown in which four feeding means 1 are provided, and the same members as in FIG. 1 are designated by the same numbers. I attached it. 106 is a hollow portion, and as shown in this figure, the hollow portion dimension
The dimension 2-X is made smaller than the dimension of the hollow part of the feeding means that comes into contact with both outer sides of the paper sheet 12, X3-Xl. Therefore, when the stacked paper sheets have large folds and the paper sheets 12 to be separated have unevenness, or when the stacked paper sheets are a large number of new banknotes with uniform printed patterns, Leaves 1
2 hits the feeding means obliquely, the friction member 101 receives a pressing force of a certain value or more and deforms greatly. At this time, the deformation resistance force of the friction member 101 is faster in the feeding means having the small hollow part 103, and the hollow part is crushed more quickly, and as shown in the P part in FIG. 10, the deformation resistance force becomes large. indicates the deformation resistance force of the feeding means having the large hollow part 106. Therefore, with this structure, the center side of the paper sheet separated by one part has a larger feeding force than both outside sides, so the paper sheet by the feeding means The force for feeding out the leaves 12 is dominant on the center side, and it is possible to prevent the occurrence of skewing of the paper sheets due to unbalanced feeding forces on the left and right sides.

Next, when the member 102 constituting the outer surface of the friction member 101 shown in FIG. Furthermore, it has been confirmed through experiments that the member 102, like the member 107, wears out relatively uniformly.

At this time, the deformation resistance force of the friction member 101 is determined by the effective actual thickness t, so even if the member 102 wears like 107, the deformation resistance force of the friction member 101 is almost negligible as shown in FIG. It does not change. Here, P.

is the deformation resistance force of the friction member 101 before wear, and P4 is the deformation resistance force of the friction member 101 after wear.

In the conventional example shown in FIG. 21, the member 102 is configured in a jagged shape, and even when a slight deformation occurs, the effective actual thickness t1 changes greatly from the effective actual thickness t2 as shown in FIG. Abrasion also causes a change in the effective actual thickness, and the deformation resistance is not stable, so the force for feeding out paper sheets is not stable.

From these facts, in FIG. 1, the position of the feeding means 1 when the feeding means 1 is in contact with the paper sheet 12,
In other words, the height is almost constant, and the pressing force on the paper sheets 12 when the friction member 101 is in contact with the paper sheets 12 can be kept constant, so that the paper sheets can be fed out stably. Because of its high strength, the 1-separation performance is stable over a long period of time.

In the above embodiment, the first member 1 in the feeding means 1
01 and the second member 102 are manufactured by molding or the like,
The case where the same parts are used is shown.

Only the member that comes into contact with the paper sheet 12 is the friction member 102,
The part of the friction member 101 that does not come into direct contact with the paper sheet 12 may be a separate member, or one member 101 and one member 102 may be used.
It may also be manufactured by gluing.

FIG. 14 shows another embodiment of the member 102,
As shown in this figure, a member 108 having convex portions such as thin hairs may be used.

Further, FIG. 15 shows another embodiment of the groove 105 shown in FIG. 5, in which the member 102 is formed by partially expanding the groove portion 109 compared to the outer peripheral surface.

FIG. 16 shows another embodiment of the member 102, in which a plurality of convex members 110 are arranged on the outer surface of the member 101.

FIG. 17 shows another embodiment of the member 101, in which a member 111 having a plurality of convex portions is disposed in the hollow portion 103.

In the above embodiment, the hollow part 103 provided in the feeding means 1 has a vibration absorbing effect when the one member 101 is deformed inward, but instead of the hollow part 103, a foam member, an anisotropic member, a multilayer Even if it is composed of structural members, etc., the effect is the same.

Furthermore, the shape of the friction member provided in the feeding means 1 is as follows:
With a line-symmetrical configuration, it is possible to have the same effect for forward and reverse rotations, and there is no problem during assembly such as erroneously attaching the friction member to the feed roller boss 104 in the opposite direction.

In addition, in a paper sheet handling device having two or more separating sections within one device, such as an automatic teller machine, the feeding means at each separating section is composed of a feeding roller boss and a replaceable friction member, If at least the shape of the feeding roller boss is made common, costs can be reduced.

Further, if the deformation characteristics of the friction member are changed by changing the width, thickness, material, hardness, etc. of the friction member, it is possible to standardize the shape of the delivery roller boss as described above.

Furthermore, if the shape of the notch of the feeding roller boss for attaching the friction member is changed to a partially changed notch shape 112 as shown in FIG. Even if the friction member is not removed, it is possible to prevent the friction member from falling off.

FIG. 19 shows another example of the shape of the notch 112 of the feed-out roller boss 104 for mounting a friction member.

Incidentally, since the coefficient of static friction is generally higher than the coefficient of dynamic friction, the rotational speed of the feeding means 1 and the separating means 2 should be adjusted to the friction member 10 in order to increase the feeding force of paper sheets due to the increase in frictional force.
1 is in contact with the paper sheet 12 or in the vicinity thereof, the speed may be set to low, and other than this, the speed may be set to high.

In the above embodiment, the present invention was applied to a paper sheet separating device having a paper sheet feeding means and a separating means, but the present invention is not limited to this.
It can also be widely applied to other thin plate-shaped materials such as separation, delivery devices, feeding devices, etc.

〔Effect of the invention〕

According to the present invention, in the paper sheet separating device that feeds the paper sheets fed out by the friction member of the feeding means to the separating section and separates the sheets, the friction member of the feeding means is the vibration absorbing means that determines the deformation characteristics of the paper sheets. and a second member constituting the outer surface thereof, or the friction member of the feeding means has an uneven outer surface, and the vibration absorbing means of the first member determines the deformation characteristics. As, a hollow part that allows deformation of the first member, a foamable member, an anisotropic member,
Since it is made of multi-layered materials, it has the effect of preventing buckling of weak paper sheets, and can accumulate a large number of folded banknotes in various states, new banknotes with the printed surface aligned in the same direction, etc. This has the effect of preventing skewing during separation and feeding when the

Since the structure is such that even if the second member of the feeding means wears out, it does not affect the deformation characteristics of the first member,
This has the effect of stabilizing the separation performance over a long period of time.
