Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a discriminating apparatus for a sheet body that forms a gap for inserting a gripping claw between stacked sheet bodies, and particularly relates to a dispensing machine and a depositing and dispensing machine. The present invention relates to a device for distinguishing a group of single-sheet bodies suitable for forming a gap for inserting a gripping claw in a group of stacked single-sheet bodies in a safe of a machine.

[Conventional technology]

Conventionally, as a device for separating a predetermined number of sheet bodies from the stacked sheet group, a gap is formed by inserting a wedge member into the sheet group, for example, as described in Japanese Patent Application Laid-Open No. 60-133778. In some cases, a fork claw is inserted into the gap, and the separated sheet is transferred by the fork claw.
The above-mentioned wedge member is attached to the support via an elastic member, and the wedge member makes an elastic swing, and the wedge member is displaced along the surface of the single sheet just below the wedge member. Because it is possible, the wedge member is prevented from getting into the sheet below.

[Problems to be solved by the invention]

When distinguishing a sheet having a predetermined thickness from the stacked sheet described above, there is a thickness even if the stacked sheet is thin paper,
On the other hand, the tip of the wedge member also has a thickness. For this reason,
In the above-described apparatus, when the wedge member is inserted into the end portion of the piled sheet body, the wedge member cannot be inserted between the sheet bodies and collides with the end of the sheet body, and the sheet body Scratching the edges,
There were defects such as breaks at the edge of the single leaf. In addition, for a sheet body having a bent shape or the like, the sheet body buckles due to the frictional force between the wedge member and the sheet body immediately before the wedge member gets over the folded shape, and the gripping device is inserted. There was a problem that a space to be obtained could not be formed, or that the deposited sheet was damaged or broken when the wedge member passed over the folded part.

Note that Japanese Patent Application Laid-Open No. 61-106351 describes a wedge member that moves horizontally. However, similarly to the above-described example, ignoring the resistance of the stacked paper to the insertion of the wedge member, it is merely a mechanical method. Specifically, the wedge member is forcibly inserted by rotating the wedge member, so that there is a problem that the stacked paper is bent or damaged.

The present invention has been made in view of such conventional circumstances, and an object of the present invention is to provide a device for discriminating a single-sheet body capable of inserting a gripping device without damaging or breaking a stacked single-sheet body. It is in.

[Means for solving the problem]

In order to achieve the above object, the present invention provides a method for forming a gap between single sheets (15) of a single sheet group deposited in a storage portion (14) to distinguish a predetermined number of single sheets. When perpendicularly protruding into the edge of a single-leaf body of the stack of single-leaf bodies, it is attached to the stacked single-leaf group so as to be rotatable in a horizontal direction via an axis (21), and is substantially the same as the surface of the stacked single-leaf body. A wedge member (1) that moves in a plane parallel to the
In the device for distinguishing single-leafed bodies provided with the distinguishing means (17) according to (8), the wedge member (18) is connected by a spring member (19) to which a spring force is applied in a horizontal direction, and The initial spring force (Fs, ₀ ) and the spring constant (k) are set so as to substantially satisfy the following mathematical expressions (1) and (2), respectively.

_{Fs, 0 = F 1 × l} 0 / ls ...... (1) Fs, 0 + k × Δls = F 1 × (l 0 + l 1) ...... (2) where the (F ₁₎ is the wedge member is secured The rush resistance due to the reaction force from the sheet body (15) at the time, (l ₀ ) is the distance between the axis and the tip of the wedge member and is parallel to the end of the sheet body in a horizontal plane. (Ls) is perpendicular to the direction of the tension of the spring member, the distance from the axis, (Δls) is the amount of extension of the spring due to rotation of the wedge member, and (l ₁ ) is the This is the amount of movement of the tip of the wedge member in a direction parallel to the end of the single-wafer in a horizontal plane.

[Action]

In such a configuration, when the wedge member is made to protrude into one position of the stack of single-leaf bodies, the reaction force received by the wedge member from the single-leaf body edge causes the wedge member to be parallel to the stacked single-leaf body edge in substantially the same plane as the single-leaf body surface. When the moment due to the restoring force of the elastic body such as a tension spring becomes greater than the moment due to the inrush reaction force, the wedge member enters between the single-leaf bodies and the stacked single-leaf group moves apart. Thus, a space is formed in which the holding device for the stacked sheet group can be inserted.

That is, as shown in FIG. 2 as an example, first, a sheet-like body discriminating means (17) is provided with a wedge member (18) by an actuator (such as a motor or an air cylinder). Go straight in the direction perpendicular to the end face of. next,
As illustrated in FIGS. 3 and 4, a wedge member (18)
When the wedge collides with the end face of the piled sheet body (15), the wedge member receives a reaction force F ₁ (rush resistance), and the wedge member moves a distance (l ₁ ) in a horizontal plane in a direction parallel to the edge of the sheet body. I do. Further, as illustrated in FIG. 5 and FIG. 6, the discrimination means (17) for the sheet-like bodies goes straight, the piled-up sheet group is separated by the wedge shape of the wedge member, and a gripping device for the piled-up sheet group is provided. A space is formed for insertion.

At this time, the wedge member is moved to a predetermined initial spring force (Fs, ₀ ).
And a spring member (19) having a spring constant (k), the spring force is applied in the horizontal direction and the connection is performed. Therefore, at the moment when the left side of Expression (2) becomes larger than the right side, the wedge member is stacked. Enter between the leaves. Therefore, a clearance space for inserting the gripping device into the stack of stacked sheets can be reliably and easily formed, and scratches and breaks on the stacked sheets are reduced.

Then, the gripping device 4 grips, rotates, and supplies the bills inserted into the deposit / withdrawal port 3 to the separation unit 5. The separation unit 5 separates the banknotes supplied by the gripping device 4 one by one and transports them to the discrimination unit 6. The discriminating unit 6 discriminates between genuine bills and counterfeit bills. Based on the discrimination result of the discriminating unit 6, the banknote determined to be a counterfeit note or a non-discriminable note is:
By the operation of the gate 13a, the banknotes accumulated in the stack portion 10 through the transport path 7 and the bills determined to be genuine bills are stored in the stack portion 1 through the transport path 8 by the operation of the gate 13b.
Banknotes that have been accumulated in 1 and have been determined to be 5,000-yen, 1,000-yen, and ten thousand-yen bills (not suitable as payment bills) are accumulated in the stack unit 12 through the transport path 9. At the time of deposit transaction, there is no counterfeit or undiscriminable ticket on the inserted banknote,

The banknote group of the stack unit 12 performs the same operation, and is then stacked on the stack unit 10. After the banknotes thus deposited are collectively collected, the banknotes are gripped by the gripping device 4, transferred to the deposit / withdrawal port 3, and returned to the customer. After the transaction with the customer is completed, the bills accumulated in the stack units 10, 11 and 12 are gripped by the gripping device 4 and deposited on the bill depositing units 14a and 14b. This completes the deposit operation. Next, when dispensing, a certain amount of banknotes is separated from the banknotes deposited on the banknote stacking section 14a by the discriminating device 17, and the banknotes are gripped by the gripper 4, and then the gripper 4 is rotated upward to rotate the banknotes. It is supplied to the separation unit 5. The bills supplied to the separation unit 5 are separated and discriminated in the same manner as in the above-described deposit processing, and are accumulated in the stack units 11 and 12. Next, the banknotes accumulated in the stack units 11 and 12 are
And discharged to the deposit / withdrawal port 3.

Next, a detailed configuration of one embodiment of the above-described bill discriminating device 17 will be described with reference to FIG. In this figure, the same reference numerals as those in FIG. 1 denote the same parts.

The bills 15 deposited on the bill depositing portion 14a are vertically movable lower plates 1
It is loaded on 64. The lower plate 164 is attached so as to be able to move up and down via a shaft 166, and a certain compliance acts on the banknote group 15 by a compression spring 165. When the push-up force exceeds a certain value, the push plate 16

On the other hand, the wedge member 18 is rotatably mounted on the bill discriminating device 17 via a shaft 21 in a horizontal direction, and is mounted on a pin 20a provided on the wedge member 18 and a bracket 22 provided on the bill discriminating device 17. The pin 20b is connected by a tension spring 19.
The bill discriminating device 17 is provided with a stopper 23 so that the wedge member 18 does not rotate too much in the horizontal direction.

Next, the operation of one embodiment of the above-described discriminating apparatus of the present invention will be described with reference to FIGS. In these drawings, the same reference numerals as those in FIG. 1 denote the same parts.

First, as shown in FIG. 2, the bill discriminating device 17 includes an actuator (not shown in the drawing), such as a motor or an air cylinder, in which the wedge member 18 moves straight in a direction perpendicular to the end face of the deposited bill 15 at a rush speed v. I do.

Next, as shown in FIGS. 3 and 4, when the wedge member 18 collides with the end face of the stacked banknote 15, the wedge member 18

The gripping device 4 can be inserted into this space.

Next, a method for setting the characteristics of the tension spring will be described.
(See FIG. 4.) The initial tension Fs, ₀ of the tension spring 19 is set as in the following equation.

_{Fs, 0 = F 1 × l} 0 / ls ...... (1) [here, the wedge member when F ₁ is fixed a wedge member 18
18 is the reaction force received from the bill edge, which is slightly smaller than the minimum inrush resistance. l ₀ is the distance between the shaft 21 and the tip of the wedge member 18 in the direction parallel to the bill edge in the horizontal plane, and ls is the distance between the direction of the tension of the tension spring and the axis 21 in the vertical direction. The spring constant k of the tension spring 19 is set as in the following equation.

Fs, ₀ + k × Δls = F ₁ × (l ₀ + l ₁ ) (2) [where k is the spring constant of the tension spring, Δls is the amount of extension of the spring due to rotation of the wedge member 18, l ₁ The amount of movement in the horizontal plane of the tip of the wedge member 18 in the direction parallel to the bill end,

When the wedge member 18 is fixed and the wedge member 18 is fixed, the waveform B enters the banknote abnormally, and when the wedge member 18 is damaged or broken at the end of the banknote, the waveform C moves the wedge member 18. This is a case where the tension spring 19 is selected as in the equations (1) and (2). (2) the wedge member 18 enters between the deposited banknotes 15 at the moment when the left side is greater than the right-hand side of the equation shows a small waveform C inrush resistance F ₁ with respect to the waveform A and B.

FIG. 8 shows the distribution of the rush resistance when the wedge member 18 is rotatable and when the wedge member 18 is fixed.

₁ is the average value of the rush resistance when the wedge member 18 is made rotatable, ₂ is the average value of the rush resistance when the wedge member 18 is fixed, and the distribution D is when the wedge member 18 is made rotatable. , Distribution E is obtained when the wedge member 18 is fixed. The rush resistance when the wedge member 18 is made rotatable is smaller than the rush resistance when the wedge member 18 is fixed, the average value is also small,
And its variance is small. That is, it is possible to suppress the occurrence of scratches and breaks on the bill ends. Therefore, according to the present embodiment, it is possible to suppress occurrence of scratches or breakage of the bill by the transaction apparatus itself in handling the bill.

The stopper 232 also serves as a part of the discriminating device 172.

11 and 12 show another embodiment of the discriminating apparatus of the present invention. In these figures, the same reference numerals as those in FIG. 2 denote the same parts. 173 is the discriminating device 17 and 183 is the wedge member 18
Reference numeral 213 corresponds to the shaft 23. Instead of the tension spring 19, a torsion spring 193 connected to the discriminating device 173 via the pin 26 is used, and the stopper 233 also serves as a part of the discriminating device 173.

FIG. 13 shows another embodiment of the discriminating apparatus according to the present invention, in which the same reference numerals as in FIG. 2 denote the same parts. 174 is the device 17, 184 is the wedge member 18, and 214 is the shaft 2.
It corresponds to 1. A compression spring 194 connected to a bracket 27 provided on a discriminating device 174 via a guide 241 is used instead of the tension spring 19, and a stopper 2
34 also serves as a part of the distinguishing device 174.

FIG. 14 shows another embodiment of the discriminating device of the present invention, in which an elastic body 195 is used, and the stopper 235 also serves as a part of the discriminating device 175.

In FIG. 15, the entire wedge member is made of an elastic body (for example, plastic), and a portion 216 where bending occurs is made thin. A stopper 236 also serves as a part of the discriminating device 176. The thin portion 216 has the same function as the tension spring 19.

Next, a desirable wedge shape of the wedge member will be described.

As described above, as shown in FIG.
The wedge member 18 provided above moves straight at a rush speed v in a direction perpendicular to the end face of the stacked banknotes by an actuator (not shown) such as a motor or an air cylinder. Next, the third
Wedge member 18 when the wedge member 18 collides with the end surface of the deposited bill 15 as shown in FIG receives a reaction force F ₁ (inrush resistor).
Further, the bill discriminating device 17 goes straight as shown in FIG.
Due to the wedge shape of the wedge member 18, the stacked single-leaf body group is separated, and a space is formed in which the holding device 4 for the stacked single-leaf body group can be inserted. Thereby, the gripping device 4 can be inserted into this space.

FIG. 16 is a perspective view of the tip end of the wedge member 18 and nn '.
View shows the vertical cross section of the tip of the wedge member 18, mm-m shows the horizontal cross section of the tip of the wedge member 18, r denotes the radius of curvature of the tip of the wedge member 18 in the vertical section direction, and R denotes the tip of the wedge member 18. This is the radius of curvature in the horizontal section direction.

Figure 17 illustrates a typical example of the change over time of the inrush resistor F _1. Waveform A ₁ represents an example where the wedge member 18 the tip of the example where the curvature radius r = 0.1 mm in the vertical section, the waveform B ₁ represents the radius of curvature r ≧ 0.3 mm of the wedge member 18 the tip of the vertical section.

FIG. 18 shows the relationship between the rush resistance that the wedge member 18 receives from the end of the stacked banknotes and the radius of curvature r of the vertical cross section of the tip of the wedge member 18. When the radius of curvature r exceeds 0.3 mm, the edge of the bill is turned up, and when the radius of curvature r is less than 0.05 mm, a piercing scratch occurs on the banknote, and the radius of curvature r is 0.05 mm to 0.3 mm as shown in the figure. when the range C ₁ inrush resistor F ₁ is small, i.e., it is possible to suppress the generation of scratches or bending to the banknote end.

That is, when the radius of curvature in the vertical cross section exceeds 0.3 mm, since the thickness in the vertical cross section of the tip of the wedge member 18 is larger than the thickness of the single leaf body, the edge of the single leaf body is turned up, When the radius of curvature in the vertical section direction is less than 0.05 mm, the thickness of the tip of the wedge member 18 in the vertical section direction can be almost the same as the thickness of the single-leaf body, but in this case, the tip of the wedge member 18 becomes a single-leaf body Although there is a risk of piercing and scratching, the radius of curvature of the tip of the wedge member 18 in the vertical section direction is 0.05
By setting the diameter to be from 0.3 mm to 0.3 mm, it is possible to suppress the occurrence of scratches or breakage of the banknote 15 by the transaction apparatus itself in handling the banknote.

Next, a description will be given of a desirable entry angle of the wedge member between the stacked sheet bodies.

As described above, when the wedge member enters the gap between the single-leaf bodies of the stacked single-leaf body group, the stacked single-leaf body group and the stacked single-leaf body edge are substantially in the same plane as the stacked single-leaf body surface. Move in parallel directions. This embodiment relates to a desirable angle of the moving direction.

Hereinafter, the operation of this embodiment will be described with reference to FIGS. 19 to 26. In these explanatory drawings, the same reference numerals as those in FIG. 1 denote the same parts. In this embodiment, the moving direction of the wedge member is taken in a direction opposite to that of the above embodiment.

First, as shown in FIG. 19, the banknote discriminating device 17 applies the wedge member 18 to the sheet group on which the wedge member 18 is deposited by an actuator (not shown), for example, a motor or an air cylinder. An angle θx (herein referred to as a plunge angle) between the direction of plunge and a perpendicular line formed on the end face of the piled sheet in substantially the same plane as the banknote group.
At a rush speed υ in a direction having

Next, as shown in FIG. 20, the wedge member 18 is
Wedge member 18 when colliding with the end face of receiving the inrush resistor F _1.

Further, as shown in FIG. 21, the bill discriminating device 17 moves straight, and the piled sheet group is separated by the wedge shape of the wedge member 18, thereby forming a space into which the holding device 4 of the piled sheet group can be inserted. Thereby, the gripping device 4 can be inserted into this space.

Figure 22 illustrates a typical example of the change over time of the inrush resistor F _1. If the waveform B ₂ is the wedge member 18 has entered a rush angle [theta] x = 0 ° banknote end, waveform A ₂ represents a case where the rush rush angle [theta] x = 20 ° to 30 °.

FIG. 23 shows the relationship between the rush resistance and the rush angle θx that the wedge member 18 receives from the end of the stacked banknotes. Inrush resistance F ₁ when the rush angle θx as shown in FIG lies 20 ° to 30 ° range C ₂ is small, i.e., it is possible to suppress the generation of scratches or bending to the banknote end.

FIG. 24 shows a place where banknotes 151 having a fold are stacked in the banknote stacking section 14a, and FIG. 25 and FIG.
The figure shows the operation in the case where the wedge member 18 enters between the folded bills 151. Rush angle θ
By setting x to 20 ° to 30 °, the probability that the wedge member 18 can get over the folded paper money with respect to the folded paper money 151 can be reduced, and the wedge member 18 and the folded paper money
Since the probability that the folded bill 151 buckles due to frictional force between the 151 can be reduced, the wedge member 18 can easily advance between the bills 15 and the spaces S ₁ , S ₂ , S ₃ and the spaces in which the gripping device 4 can be inserted. the S ₄ can be easily formed.

As described above, a wedge member is provided at one portion of the stacked sheet body group.
When the wedge member 18 is pushed in, the wedge member receives a reaction force from the end of the sheet body. In this embodiment, the direction in which the wedge member 18 enters the sheet group accumulated at this time and the sheet body surface The angle formed by the perpendicular to the end face of the piled sheet in the substantially same plane was 20 ° to 30 °, so that when this wedge member protruded into the edge of the leaf, the wedge member was placed in the piled sheet. It has a partial velocity υx (see FIGS. 25 and 26) in a direction parallel to the end, and the wedge member can be moved in a direction parallel to the end of the piled sheet by this partial velocity υx. Therefore, the intrusion resistance that the wedge member receives from the end of the single-leaf body is reduced, the wedge member enters between the single-leaf body and the single-leaf body, the stacked single-leaf group is separated, and the holding device for the stacked single-leaf group is inserted. A space to gain is formed.

In addition, for a folded sheet such as a banknote, when the inclination angle is increased, the wedge member needs to get over the above-mentioned folded body.However, the wedge member is required to get over the folded case. Receives a large reaction force from the single-leaf body. That is, the sheet body buckles due to the frictional force between the wedge member and the sheet body, and a space in which the gripping device can be inserted cannot be formed, or the wedge member may damage the folded portion of the sheet body. However, in the present embodiment, the inclination angle is as small as 20 ° to 30 °, so that the probability that the wedge member can get over the bent side can be reduced.
The wedge member can easily advance between the piled sheet bodies, and a space in which the holding device for the piled sheet group can be inserted can be easily formed.

In the above embodiments, bills have been described. However, the present invention can be used in common for separation of stacked sheets such as postcards and passbooks.

Claims (1)

(57) [Claims] A single sheet of the stacked sheet group is formed in order to form a gap between the sheets (15) of the sheet group deposited in the storage portion (14) to distinguish a predetermined number of sheets. When perpendicularly penetrating the body edge, an axis (21)
And a discriminating means (17) provided by a wedge member (18) which is mounted to be rotatable in the horizontal direction via a plane and moves in a direction substantially parallel to the end of the piled sheet body in the same plane as the plane of the piled sheet body. In the single-leaf-body discriminating apparatus, the wedge member (18) is provided with a spring member (1) to which a spring force is applied in a horizontal direction.
9), and the initial spring force (Fs, ₀ ) and the spring constant (k) of the spring member are set so as to substantially satisfy the following equations (1) and (2), respectively. Leaf body discriminator. _{Fs, 0 = F 1 × l} 0 / ls ...... (1) Fs, 0 + k × Δls = F 1 × (l 0 + l 1) ...... (2) where the (F ₁₎ is the wedge member is secured The rush resistance due to the reaction force from the sheet body (15) at the time, (l ₀ ) is the distance between the axis and the tip of the wedge member and is parallel to the end of the sheet body in a horizontal plane. Distance in the direction
