Description

The present invention relates to an apparatus for determining the denomination of cylindrical coins, for example, which is provided in an automatic changer machine used in banking business, and more particularly to a cylindrical coin denomination apparatus. The present invention relates to a cylindrical coin denomination determining device capable of accurately determining a coin denomination.

(B) Conventional technology Generally, a device for determining the denomination of a cylindrical coin provided in an automatic money changer or the like is a device that determines the denomination by measuring the outer diameter of the cylindrical coin. Since the outer diameters of a 1-yen coin and a 50-yen coin are similar, and the outer diameters of a 5-yen coin and a 100-yen coin are similar, the denomination of the cylindrical coin is determined from the outer diameter of the cylindrical coin. It was difficult to find precisely.

Therefore, a device that detects the material of the coin and determines the denomination of the cylindrical coin is also known. However, in this case, the structure for determining the material is complicated and has a problem of increasing the size. .

(C) Problems to be Solved by the Invention The present invention focuses on the outer diameter and the length of a cylindrical coin that differs for each denomination, and uses these as a denomination determining element, whereby the It is an object of the present invention to provide a cylindrical coin denomination determining device capable of easily and accurately detecting all denominations.

(D) Means for Solving the Problems The present invention relates to a denomination determining device for a cylindrical coin, which determines a denomination of a cylindrical coin in which a certain number of coins are piled up and wrapped in a cylindrical shape. The coin is divided into three-step outer diameters of a large diameter, a medium diameter, and a small diameter, an outer diameter detecting means for detecting the outer diameter, and the entire length of the cylindrical coin is divided into a long side and a short side, A cylindrical coin denomination determining device comprising: a length detecting means for detecting the length dimension; and a denomination determining means for determining a denomination of the cylindrical coin based on the detection results of the two detecting means. .

According to the present invention, when the denomination of a cylindrical coin is determined,
The outer diameter detecting means detects whether the outer diameter of the cylindrical coin is one of three stages of a large diameter, a medium diameter, and a small diameter, and the length detecting means makes the entire length of the cylindrical coin shorter or longer from the long side. The denomination determining means determines the denomination of the cylindrical coin by detecting which of the two stages is the side, and combining these detection results.

(F) Effect of the Invention As described above, since the outer diameter and thickness of coins differ for each denomination, if the number of wrapped cylindrical coins is the same, the outer diameter and total length of the cylindrical coins for each denomination Has a different shape in proportion to this, the denomination of the cylindrical coin can be accurately determined from the outer diameter and full length dimensions that are unique to this denomination. It is not necessary to have a complicated structure for detecting the above, and it can be made compact.

(G) Embodiment One embodiment of the present invention will be described in detail below with reference to the drawings.

The drawing shows a cylindrical coin denomination determining apparatus. In FIGS. 1 and 2, the cylindrical coin denomination determining apparatus 11 includes a hanger 13 for placing and transporting a cylindrical coin 12 and an outer diameter detecting apparatus. Mechanism 14
And a length detecting mechanism 15.

Cylindrical coins 12 applied to this denomination judgment device 11 are circulation coins of six denominations of 1 yen, 5 yen, 10 yen, 50 yen, 100 yen and 500 yen, and 50 coins for each denomination The two ends of the cylindrical coin set 12 are placed and conveyed by a pair of left and right hangers 13, 13 having an upwardly directed half-moon shape. , 13 are conveyed and moved in a loop, so that each cylindrical coin 12 is continuously conveyed to the detection position.

The above-described detection positions include the outer diameter detection mechanism 14 and the length detection mechanism.
The two detection mechanisms 14 and 15 are provided to simultaneously measure the denomination determining elements of the outer diameter and the entire length of the cylindrical coin 12 guided thereto.

The outer diameter detection mechanism 14 includes an outer diameter detection lever 16, a first detection sensor S1, and a second detection sensor S2, of which the outer diameter detection lever 16 is conveyed in a horizontally long state orthogonal to the conveyance direction. Arranged above the cylindrical coin transport line 17, the intermediate portion is pivotally supported by the pivot pin 18, and is allowed to tilt forward and backward along the transport direction, and a peripheral surface corresponding roller 19 is mounted on the tip side, The detection corresponding portion 20 is provided on the end end side, and the distal end side of the lever 16 is normally a cylindrical coin by the urging action of the urging spring 21 connected to the base end side.
It is in a forward tilted state in which it is tilted downward to a position where it can correspond to the outer peripheral surface of the lever 12, and this forward tilt standby position is positioned by an upward movement stopper 22 disposed on the upper portion on the base end side of the lever and stands by.

And a cylindrical coin guided to this detection position at a constant speed
The peripheral surface corresponding roller 19 comes into contact with the outer peripheral surface of
Tilts. In this case, the amount of tilt of the lever 16 varies in proportion to the outer diameter of the cylindrical coin 12, but at this time, the first detection sensor S1 and the second detection sensor S1 are located at the tilt corresponding positions corresponding to the detection corresponding portions 20 on the lever base end side. The two detection sensors S2 are provided to detect the degree of tilt of the lever 16 at that time.

In this case, the outer diameter of the cylindrical coin 12 has a certain packaging error depending on the packaging state, but in the distribution state,
As shown in FIG. 3, it is known that the size of coins increases from small diameter to large diameter in the order of 1 yen → 50 yen → 5 yen → 100 yen → 10 yen → 500 yen.

The outer diameters of these coins can be divided into three stages: a small diameter group S of 1 yen / 50 yen, a medium diameter group M of 5 yen / 100 yen, and a large diameter group L of 10 yen / 500 yen. The size between the small diameter group S and the medium diameter group M is detected by the first detection sensor S1, and the size between the medium diameter group M and the large diameter group L is detected by the second detection sensor S2. Thus, the outer diameter group breath corresponding to each denomination can be obtained, and a specific denomination is obtained by obtaining this and a length group described later.

In addition, the length detection mechanism 15 includes a reference end surface corresponding roller 23,
It comprises a length detection lever 24 and a third detection sensor S3, of which the reference end surface corresponding roller 23 is disposed at one side position of the cylindrical coin transport line 17, and is guided to the cylindrical The one end face of the coin 12 is brought into contact with the coin, and this position is used as a reference contact surface for measuring the length. Pin 25
The front and rear parts are allowed to tilt in the left and right direction, and the front end is equipped with an end face corresponding roller 26, and the base end is a detection corresponding part
The lever 24 is normally inclined by a biasing action of a biasing spring 28 connected to the base end thereof to a position where the distal end of the lever 24 can be brought into contact with the end face of the cylindrical coin 12. The position is determined by a lateral stopper 29 disposed on the outer side of the lever proximal end side, and stands by.

And a cylindrical coin guided to this detection position at a constant speed
While one end face of 12 is in contact with the reference end face-corresponding roller 23, the other end face is in contact with the end face-corresponding roller 26 and temporarily passes through the pinching state, and the length detecting lever 24 that tilts at this time.
A third detection sensor S3 is disposed at a position corresponding to the detection corresponding portion 27 on the base end side of the coin, and the detection sensor S3 detects the tilt angle of the lever 24 that tilts in proportion to the length of the cylindrical coin 12. Like that.

In this case, the length of the cylindrical coin 12 has a certain packaging error depending on the packaging state, but in the distribution state,
As shown in FIG. 4, it is known that coins become longer in the order of 10 yen → 5 yen → 1 yen → 100 yen → 50 yen → 500 yen coin.

These coins have a cylinder length of 10 yen, 5 yen, and 1 yen, and a long group of 100 yen, 50 yen, and 500 yen.
By detecting the dimension between the short group SG and the long group LG with the third detection sensor S3, the length group area corresponding to each denomination can be obtained. It is possible to obtain a specific denomination by obtaining both this and the outer diameter group described above.

FIG. 5 is a control circuit block diagram of the denomination determining device for cylindrical coins. The CPU 51 provides each circuit device according to a program stored in the ROM 52, and stores the control data in the RAM 53.

The hanger driving device 54 drives each of the hangers 13 at a constant speed by driving a motor (not shown), and during this driving, the shape data of the outer diameter and the cylinder length, which are the denomination determining elements of the cylindrical coin 12, is It is determined by the sensors S1 to S3, and based on this, the CPU 5
1 determines the denomination.

As shown in FIG. 6, when the CPU 51 guides the cylindrical coin 12 of the small diameter group S such as 1 yen / 50 yen to the position of the cylindrical coin denomination judging device 11, as shown in FIG. The outer diameter detection lever 16 is slightly tilted in conjunction with this, and as a result, only the first detection sensor S1 detects the outer diameter, and the second detection sensor S2 remains in the non-detection state. Is determined. At this time, the length detecting lever 24 also tilts, and the third detecting sensor S3 detects the length degree of the cylindrical coin 12, and
Short group SG of 10 yen, 5 yen, 1 yen coin or 100 yen, 50 yen
It is determined whether a long group LG is a yen / 500 yen coin. As a result, if the detection condition is that the cylindrical coin group 12 is the short group SG in addition to the small diameter group S, it is determined that the coin is a single cylindrical cylinder. Is possible, in addition to the small diameter group S, the long group LG
With such a detection condition, it can be determined that the coin is a cylindrical coin of 50 yen.

When the cylindrical coin 12 of the medium diameter group M such as 5 yen or 100 yen is guided, the outer diameter detection lever 16 is linked with this.
However, the first detection sensor S1 and the second detection sensor S2 detect and correspond to each other by tilting to some extent. At this time, since the outer diameter detection lever 16 returns to tilt relatively quickly because of the middle diameter, the second detection sensor S2 The detection time is short, and as a result, the CPU 51 determines that the medium is the medium diameter group M. In addition, similarly to the case of the small diameter group S, one of the long and short groups SG and LG detected by the third detection sensor S3 via the length detection lever 24 is obtained. The denomination of the cylindrical coin having a unique outer shape of the denomination is determined.

Furthermore, when the cylindrical coin 12 of the large diameter group L such as 10 yen / 500 yen is guided, the outer diameter detection lever is interlocked with this.
When the first detection sensor S1 and the second detection sensor S2 detect and correspond to each other, the outer diameter detection lever 16 tilts greatly due to the large diameter, and the detection time of the second detection sensor S2 is large. As a result, the CPU 51 determines that the group is the large diameter group L. In addition, small diameter group S
As in the case of the above, one of the long and short groups SG and LG detected by the third detection sensor S3 via the length detection lever 24 is obtained, and from both of these detection groups, the CPU 51 has a unique outer shape of a denomination. The denomination of the cylindrical coin is determined.

As described above, the denomination of the cylindrical coin can be accurately determined from the outer diameter and the overall length, which are unique characteristics of the denomination. In particular, the three detection sensors of the first to third detection sensors are used. It can be used effectively to determine six denominations efficiently, without the need for a complicated structure for detecting the material of coins.
It can be made compact.

In correspondence between the present invention and the configuration of the above-described one embodiment, the outer diameter detecting means of the present invention is the same as the outer diameter detecting mechanism 14 of the embodiment.
In the same manner, the length detecting means corresponds to the length detecting mechanism 15, the large diameter corresponds to the large diameter group L, the medium diameter corresponds to the medium diameter group M, and the small diameter corresponds to Although the long side corresponds to the long group LG, the short side corresponds to the short group SG, and the denomination determining means corresponds to the CPU 51, the present invention is not limited to the above-described embodiment. However, the present invention is not limited only to the above configuration.
