Description

Detailed Description of the Invention (a) Industrial Application Field The present invention relates to a device for determining the denomination of a cylindrical coin, such as that installed in an automatic money changer used in banking, and more specifically, The present invention relates to a cylindrical coin denomination determining device that can accurately determine the denomination of a coin.

(b) Conventional technology It is generally known that the denomination determination device for cylindrical coins installed in automatic money changers etc. 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 can be determined from the outer diameter of the cylindrical coin. It was difficult to obtain accurately.

Therefore, devices are known that detect the material of the coin and determine the denomination of a cylindrical coin, but in this case, the structure for determining the material is complicated and the device becomes large. .

(c) Problems to be Solved by the Invention This invention focuses on the outer diameter and length of the cylindrical coin, which differ for each denomination, and uses these as factors for determining the denomination.
To provide a denomination determination device for cylindrical coins that can easily and accurately detect all denominations of cylindrical coins.

(d) Means for Solving the Problems The present invention is a cylindrical coin denomination determining device for determining the denomination of a cylindrical coin made by stacking a certain number of coins and wrapping them in a cylindrical shape.
an outer diameter detection means for dividing the cylindrical coin into three stages of outer diameter dimensions, ie, a large diameter, a medium diameter, and a small diameter; and an outer diameter detection means for detecting the outer diameter dimension; and a denomination determination means for determining the denomination of the cylindrical coin based on the detection results of both the detection means. It is a device.

(E) Effect of the Invention According to this invention, when determining the denomination of a cylindrical coin, the outer diameter detection means determines the outer diameter of the cylindrical coin in one of three stages: large diameter, medium diameter, and small diameter. The length detection means detects whether the cylindrical coin is in one of two stages: the full length, the long side, or the short side. By combining these detection results, the denomination can be determined. The determining means determines the denomination of the cylindrical coin.

(f) Effects of the invention In this way, since the outer diameter and thickness of the coin differs depending on the denomination, if the number of wrapped cylindrical coins is the same, the outer diameter and total length of the cylindrical coin will vary depending on the denomination. It is possible to accurately determine the denomination of a cylindrical coin from the outside diameter and overall length dimensions, which are unique characteristics of this denomination. It does not require a complicated structure for detection and can be configured compactly.

(g) Examples An embodiment of the present invention will be described in detail below based on the drawings.

The drawings show a device for determining the denomination of a cylindrical coin, and in FIGS. It is composed of a mechanism 14 and a length detection mechanism 15.

The cylindrical coin 12 applied to this denomination determination device 11 is 1
Circulating coins of six denominations: yen, 5 yen, 10 yen, 50 yen, 100 yen, and 500 yen are packaged in units of 50 for each denomination and handled one by one. 12 with a pair of left and right hangers 13, 13 each having an upward half-moon shape! This pair of left and right hangers 13,1
A large number of cylindrical coins 12 are conveyed and moved in a loop.
is configured to continuously convey the information to the detection position.

The above-mentioned detection position is equipped with both detection mechanisms 14.15, an outer diameter detection mechanism 14 and a length detection mechanism 15, to determine the denomination determination element of the outer diameter and total length of the cylindrical coin 12 guided there. I try to measure them at the same time.

The outer diameter detection mechanism 14 is equipped with 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 transported in a horizontally long state perpendicular to the transport direction. It is arranged at a position above the cylindrical coin conveyance line 17, and the middle part is pivotally supported by a pivot pin 18 to allow tilting back and forth along the conveyance direction, and a peripheral surface corresponding roller 19 is attached to the tip side, A detection corresponding part 20 is provided on the proximal end, and normally the lever 1 is biased by a biasing spring 21 connected to the proximal end.
6 is in a forward tilted state in which it is tilted downward to a position where it can come into contact with the outer circumferential surface of the cylindrical coin 12, and this forward tilted standby position is reached by the upward movement stopper 22 disposed at the upper part of the base end of the lever.
It is positioned and waiting.

The cylindrical coin 1 is guided to this detection position at a constant speed.
The lever 16 is tilted in contact with the outer circumferential surface of the roller 19 corresponding to the circumferential surface. In this case, the amount of tilting of the lever 16 differs in proportion to the outer diameter of the cylindrical coin 12, but the first detection sensor S1 and the first detection sensor S1 and 2 detection sensor S2 is arranged,
The degree of tilting of the lever 16 at that time is detected.

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

The outer diameters of these coins are small diameter group S of 1 yen and 50 yen, medium diameter group M of 5 yen and 100 yen, and 10 yen and 50 yen.
It can be divided into three stages: a large diameter group L of 500 yen, and the size between the small diameter group S and the medium diameter group M is detected by the first detection sensor Sl, and the medium diameter group M and the large diameter group By detecting the dimension between groups with L with the second detection sensor S2, it is possible to determine the outer diameter group area corresponding to each denomination, and by determining this and the length group described later, a specific I'm trying to find a denomination.

Further, the length detection mechanism 15 includes a reference end face corresponding roller 23, a length detection lever 24, and a third detection sensor S3. It is arranged at a side position and comes into contact with the end face of the cylindrical coin 12 guided here, and measures the length using this position as a reference contact surface, and is arranged at the other side opposite to this. The provided length detection lever 24 has an intermediate portion pivoted on a pivot pin 25 and is allowed to tilt in the front and rear directions in the left and right directions, has an end face corresponding roller 26 attached to the tip, and has a detection lever 24 at the base end. It is provided with a corresponding portion 27, and is normally tilted to a position where the distal end side of the lever 24 can come into contact with the end surface of the cylindrical coin 12 by the biasing action of a biasing spring 28 connected to the proximal end side. This inclined position is determined by a lateral movement stopper 29 disposed on the outer side of the base end of the lever and is on standby.

The cylindrical coin 1 is guided to this detection position at a constant speed.
The length detection lever 2 passes temporarily in a pinched state while one end surface of the 2 is in contact with the reference end surface corresponding roller 23, and the other end surface is in contact with the end surface corresponding roller 26, and the length detection lever 2 is tilted at this time.
A third detection sensor S3 is disposed at a position corresponding to the detection corresponding part 27 on the base end side of the coin 1.
The tilting angle of the lever 24, which tilts in proportion to the length of the lever 24, is detected.

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

The cylinder lengths of these coins can be divided into two stages: short groups SG of 10 yen, 5 yen, and 1 yen, and long groups LG of 100 yen, 50 yen, and 500 yen. By detecting the dimension between the long group LG and the group with the third detection sensor S3, the length group area corresponding to each denomination can be determined, and both this and the outer diameter group described above can be determined. By asking, you are asking for a specific denomination.

FIG. 5 shows a control circuit block diagram of the denomination determination device for cylindrical coins, in which the CPU 51 controls each circuit device according to the program stored in the ROM 52, and transmits the control data to the RA.
Store in M53.

The hanger driving device 54 drives each hanger 13 at a constant speed by driving a motor (not shown), and during this driving, the shape data of the outer diameter and cylinder length, which are factors for determining the denomination of the cylindrical coin 12, is collected. is determined by each sensor S1 to S3, and based on this, the CPU 51 determines the denomination.

As shown in FIG. 6, when the CPU 51 introduces a cylindrical coin 12 of a small diameter group S such as 1 yen or 50 yen to the position of the cylindrical coin denomination determination device 11, The outer diameter detection lever 16 is slightly tilted in conjunction with
It is determined that At this time, the length detection lever 24
Similarly, the third detection sensor S3 detects the length of the cylindrical coin 12 by tilting, and selects the short group SG of 10 yen, 5 yen, and 1 yen coins, or the short group SG of 100 yen, 50 yen, and 500 yen coins. As a result, if the detection condition is that the cylindrical coin 12 is in the short group SG in addition to the small diameter group S, it can be determined that it is a 1 yen cylindrical coin, and the coin is in the small diameter group S. In addition, if the detection condition is long group LG, it can be determined that the coin is a 50 yen cylindrical coin.

Further, when a cylindrical coin 12 of medium diameter group M such as 5 yen or 100 yen is guided, the outer diameter detection lever 16 tilts to some extent in conjunction with this, and the first detection sensor S1 and the second detection sensor
Both detection sensors S2 respond to detection, and at this time, because of the medium diameter, the outer diameter detection lever 16 returns to its tilting position relatively quickly.
The detection time of the second detection sensor S2 is short, and as a result, CP
It is determined that U51 is a medium diameter group M. Also,
In addition, as in the case of the small-diameter group S, the CPU 51 determines which of the long and short groups SG and LG detected by the third detection sensor S3 via the length detection lever 24 is detected from both detection groups. Determine the denomination of a cylindrical coin having a unique outer shape for each type.

Furthermore, when a cylindrical coin 12 of a large diameter group L such as -0 yen or 500 yen is guided, the outer diameter detection lever 16 is tilted greatly in conjunction with this, and the first detection sensor S1 and the first detection sensor S1 are Both of the second detection sensors S2 respond to the detection, and at this time, due to the large diameter, the outer diameter detection lever 16 tilts significantly, and the detection time of the second detection sensors S2 becomes longer, and as a result, the CPU 51
It is determined that there is a large diameter group. In addition, as in the case of the small diameter group S, the length is detected and either the long or short group SG or LG detected by the third detection sensor S3 is determined via the bar 24, and from both of these detection groups. The CPU 51 determines the denomination of the cylindrical coin, which has a unique outer shape for each denomination.

In this way, the denomination of a cylindrical coin can be accurately determined from the outer diameter dimension and overall length dimension, which are unique characteristics of the denomination.
In particular, by effectively utilizing the three detection sensors 1st to 3rd detection sensors, it is possible to efficiently determine six denominations, and it is compact and does not require a complicated structure to detect the material of the coin. It can be configured as follows.

In correspondence between this invention and the configuration of the above-mentioned embodiment, the outer diameter detection means of this invention is the outer diameter detection mechanism 14 of the embodiment.
Similarly, the length detection means corresponds to the length detection mechanism 15, and the large diameter is
The medium diameter corresponds to the medium diameter group M, the small diameter corresponds to the small diameter group S, the long side corresponds to the long group LG, and the short side corresponds to the short group SG. Although the denomination determining means corresponds to the CPU 51, the present invention is not limited to the configuration of the above-described embodiment.
