<Configuration of coin recognition device>
Hereinafter, the configuration of the coin recognition device 10 will be described with reference to FIGS. 2 and 3. FIG. 2 is a perspective view showing the configuration of the coin recognition device 10. FIG. 3 is an explanatory view showing a state in which the transport cover 16 (cover member) described later of the coin recognition device 10 is removed. In the following description, the "upstream side" and the "downstream side" are based on the coin transport direction (direction of arrow A12). In the present embodiment, it is assumed that the coin has the shape of a disk.

As shown in FIGS. 2 and 3, the coin recognition device 10 includes a transport surface 11, a pin belt 12, a detection unit 13, a regulation member 14, a width adjusting arm 15, and a transport cover 16 (see FIG. 2). , Is equipped.

The transport surface 11 is a surface on which the coin 90 is transported.
The pin belt 12 is a transport member that transports coins 90 along the transport surface 11.
The detection unit 13 is a component that detects the characteristics of the coin 90.
The regulating member 14 is a member that regulates the transporting direction of the coin 90 being transported.
The width-aligning arm 15 is a pressing member that presses the coin 90 against the regulation surface 20.
The transport cover 16 (see FIG. 2) is a cover member that regulates the lifting of the coin 90 from the transport surface 11 at a position separated from the regulation surface 20.

The transport surface 11 is formed in a substantially flat shape, and coins 90 are transported along the extending direction. In this embodiment, the transport surface 11 is formed as a horizontal plane. A second sensor SN2, which will be described later, is embedded in the transport surface 11.

The pin belt 12 is arranged above the transport surface 11 at least in the vicinity of the detection unit 13. The pin belt 12 is arranged along the extending direction of the transport surface 11 so as to pass through a position closer to the regulation surface 20 than the center position in the width direction of the transport surface 11. The pin belt 12 has a belt 12a and a plurality of pins 12b. The belt 12a is formed in an annular shape by a flexible material such as rubber. Each pin 12b is formed in a rod shape by a material such as a relatively strong metal material or a resin material. The pins 12b are arranged at equal intervals so as to project from the lower surface of the belt 12a toward the transport surface 11.

The pin belt 12 is driven by a drive unit (not shown) and travels in the transport direction (direction of arrow A12). At that time, the pin belt 12 conveys the coin 90 in the direction of the detection unit 13 by bringing the pin 12b into contact with the side surface of the coin 90 arranged on the conveying surface 11. However, the means for transporting the coin 90 is not limited to the pin belt 12, and may be configured by, for example, a transport roller.

The detection unit 13 has a first sensor SN1 and a second sensor SN2. Here, the first sensor SN1 is configured as a diameter sensor for magnetically detecting the outer diameter of the coin 90, and the second sensor SN2 is a material / material for magnetically detecting the material and material thickness of the coin 90. It will be described as being configured as a thickness sensor. In the illustrated example, the first sensor SN1 is arranged above the transport surface 11 by the holding portion 13a. The second sensor SN2 is embedded in the transport surface 11 so as to face the first sensor SN1. When the coin 90 passes between the first sensor SN1 and the second sensor SN2, the detection unit 13 detects features such as the outer diameter, material, and material thickness of the coin 90 by the first sensor SN1 and the second sensor SN2. To do. However, the detection unit 13 is not limited to such a configuration, and various changes can be made depending on the operation.

The regulating member 14 is formed as a plate-shaped member. The regulating member 14 is arranged on one side in the width direction of the transport surface 11 along the extending direction of the transport surface 11. The regulating member 14 has a regulating surface 20 that forms one wall surface of the transport surface 11 in the transport direction. The regulation surface 20 is arranged at one edge of the transport surface 11 so as to face the transport surface 11 along the extending direction of the transport surface 11. The regulation surface 20 has a slope 21 that presses the coin 90 being transported against the transport surface 11. The slope 21 is formed in an inclined surface shape or an arc surface shape so as to face the transport surface 11. The slope 21 can be formed on the entire surface of the regulation surface 20 (see, for example, FIGS. 4 and 10C). The slope 21 can also be formed on a part of the regulation surface 20 (see, for example, FIGS. 10A and 10B). Here, as shown in FIG. 4, the slope 21 will be described as being formed in an inclined surface shape on the entire surface of the regulation surface 20.

The width adjusting arm 15 is formed as a long rod-shaped member, and is arranged on the other side in the width direction of the transport surface 11 along the extending direction of the transport surface 11 so as to face the regulation surface 20. (See Fig. 3). The upstream end of the width-aligning arm 15 is rotatably supported by a fulcrum portion 15a erected on the transport surface 11. A portion of the width-aligning arm 15 on the downstream side of the fulcrum portion 15a (in the illustrated example, the lower end of the width-aligning arm 15) is urged in the direction of the regulation surface 20 by the spring 15b. With such a configuration, the width adjusting arm 15 is configured to rotate in the direction of the pin belt 12 about the fulcrum portion 15a.

The width-aligning arm 15 is arranged at a position upstream of the detection unit 13 so as to intersect the transport direction of the smallest coin in circulation (1 yen coin in Japan). That is, the width-aligning arm 15 is located upstream of the detection unit 13 in a state where it does not come into contact with the coin 90, and the distance between the width-aligning arm 15 and the regulation surface 20 is larger than the diameter of the coin having the minimum diameter. It is arranged so that it becomes smaller.

The coin 90 is conveyed by the pin belt 12 from the upstream side to the downstream side of the width-aligning arm 15 arranged in this way. At that time, the coin 90 comes into contact with the width-aligning arm 15, and while being urged by the width-aligning arm 15 and pressed against the regulation surface 20, the coin 90 is pushed by the pin belt 12 and advances to the downstream side. As a result, the coin 90 passes between the width-aligning arm 15 and the regulation surface 20. When the coin 90 passes between the coin 90 and the regulation surface 20, the width-aligning arm 15 is pushed by the coin 90 and rotates so that the distance between the coin 90 and the regulation surface 20 increases. That is, the coin 90 is pushed by the pin belt 12 and advances to the downstream side while rotating the width-aligning arm 15 so as to increase the distance between the width-aligning arm 15 and the regulation surface 20. Then, when the coin 90 passes between the coin 90 and the regulation surface 20, the width adjusting arm 15 rotates toward the regulation surface 20 and returns to the original state.

It is assumed that the coin 90 conveyed from the upstream side of the Tailgating arm 15 may hit the vicinity of the fulcrum portion 15a of the Tailgating arm 15. In this case, since the coin 90 has the shape of a disk, it is pushed by the pin belt 12 and advances to the downstream side while rolling. Therefore, even if such a case occurs, the coin 90 is conveyed to the downstream side without staying in the vicinity of the fulcrum portion 15a of the width-aligning arm 15 (without causing jam).

The transport cover 16 (see FIG. 2) is formed as a plate-shaped member. The transport cover 16 is arranged along the extending direction of the transport surface 11 so as to cover a part of the other side (the side facing the regulating member 14) in the width direction of the transport surface 11. ). The transport cover 16 is preferably made of a plastic material so as not to interfere with the magnetic detection accuracy of the first sensor SN1 and the second sensor SN2, and more preferably an antistatic coating is applied.

In such a configuration, when the coin recognition device 10 detects the feature of the coin 90, the coin 90 arranged on the transport surface 11 is moved in the direction of the detection unit 13 by traveling the pin belt 12 in the direction of the arrow A12. Transport. During the transportation, the coin 90 enters between the width-aligning arm 15 and the regulation surface 20 from the upstream side as the pin belt 12 travels. Then, the coin 90 comes into contact with the width adjusting arm 15 and the regulation surface 20. At this time, the width adjusting arm 15 presses the coin 90 against the regulation surface 20 by the urging force of the spring 15b. The driving force of the driving unit (not shown) that drives the pin belt 12 is set to a value larger than the force that hinders the transportation of the coin 90 by the spring 15b. Therefore, after the coin 90 comes into contact with the width adjusting arm 15 and the regulation surface 20, the coin 90 advances in the direction of the detection unit 13 along the regulation surface 20 as the pin belt 12 travels. At that time, the coin 90 rotates the width-aligning arm 15 in a direction away from the regulation surface 20 so that the distance between the width-aligning arm 15 and the regulation surface 20 increases. Then, when the coin 90 passes through the detection unit 13, the coin recognition device 10 detects the feature of the coin 90 by the detection unit 13.

The coin recognition device 10 is configured to sandwich the coin 90 between the width adjusting arm 15 and the regulation surface 20 so that the coin 90 conveyed by the pin belt 12 does not shift laterally when the coin 90 is conveyed. At that time, the coin recognition device 10 has a slope 21 formed on the regulation surface 20 so as to face the transport surface 11 so that the coin 90 does not emerge on the regulation surface 20 side. Further, the coin recognizing device 10 has a transport cover 16 (see FIG. 2) on the width-aligning arm 15 side so that the coin 90 does not come up on the width-aligning arm 15 side.

<Regulatory structure>
Hereinafter, the configuration of the regulation surface 20 will be described with reference to FIG. FIG. 4 is an explanatory diagram schematically showing the configuration of the regulation surface 20. FIG. 4 shows a state in which the coin 90 arranged on the transport surface 11 is in contact with the slope 21 of the regulation surface 20.

In the example shown in FIG. 4, the regulation surface 20 has a structure having a slope 21 formed in an inclined surface shape so as to face the transport surface 11. Therefore, the coin recognizing device 10 presses the coin 90 against the slope 21 of the regulation surface 20 with the width adjusting arm 15 to generate a force for pressing the coin 90 being conveyed by the slope 21 of the regulation surface 20 against the regulation surface 20. Can be done. As a result, the coin recognizing device 10 can suppress the lifting of the coin 90 during transportation on the regulation surface 20 side. As a result, in the example shown in FIG. 4, the coin 90 and the transport surface 11 are in close contact with each other. In the example shown in FIG. 4, the angle θ [°], the thickness (height) H [mm], and the distance D [mm] are shown. These will be explained in the chapter "Structure that suppresses the lifting of coins" described later.

<Structure that suppresses the lifting of coins>
Hereinafter, a configuration for suppressing the lifting of the coin 90 will be described with reference to FIGS. 5 to 8. FIG. 5 is an explanatory diagram showing changes in the contact position with the regulation surface 20 depending on the type of coin 90. FIG. 6 is an explanatory diagram of a configuration for suppressing the lifting of the coin 90 on the regulation surface 20 side. FIG. 7 is an explanatory diagram showing a virtual model when the coin 90 is in close contact with the slope 21 of the regulation surface 20. FIG. 8 is an explanatory diagram of a configuration for suppressing the lifting of the coin 90 on the side of the width adjusting arm 15.

FIG. 5 shows a state in which a relatively large coin 90a (see the solid line portion) and a coin 90b smaller than the coin 90a (see the alternate long and short dash line portion) are in contact with the slope 21 of the regulation surface 20. As shown in FIG. 5, the coin 90 has a different thickness (height) depending on the type. Therefore, the contact position of the coin 90 with the slope 21 of the regulation surface 20 varies depending on the type. Therefore, the coin recognizing device 10 has a change in the contact position in the lateral direction and a change in the contact position in the height direction between the slope 21 of the regulation surface 20 and the coin 90 due to the difference in the type of the coin 90. Occurs. In such a coin recognizing device 10, there is a possibility that the coin 90 may be laterally displaced during transportation and the coin 90 may be lifted due to the difference in the type of the coin 90.

Therefore, with respect to the coins 90 in circulation (preferably a plurality of types of coins in circulation 90, more preferably all types of coins in circulation 90), a lateral deviation of the coins 90 during transportation is performed. When it is desired to suppress the runout width to ΔD [mm] or less, it is preferable to satisfy the first condition below.

但し、θ［°］は搬送面１１と規制面２０のスロープ２１とが成す角度である。
ΔＨ［ｍｍ］は硬貨９０の種類の違いによる厚さ（高さ）方向の振れ幅である。
ΔＤ［ｍｍ］は硬貨９０の種類の違いによる横方向の振れ幅である。 (First condition)
The slope 21 of the regulation surface 20 is a coin 90 in which the angle θ [°] shown in FIG. 5 is in circulation (preferably, a plurality of types of coins in circulation 90, and more preferably all types in circulation. The coin 90) shall have a configuration that satisfies the following formula (1). The grounds for the following formula (1) will be described later.

However, θ [°] is the angle formed by the slope 21 of the transport surface 11 and the regulation surface 20.
ΔH [mm] is the swing width in the thickness (height) direction due to the difference in the type of coin 90.
ΔD [mm] is the lateral swing width due to the difference in the type of coin 90.

Further, with respect to the coins 90 in circulation (preferably a plurality of types of coins in circulation 90, more preferably all types of coins in circulation 90), the coins 90 on the regulatory surface 20 side If it is desired to suppress the lifting, it is advisable to satisfy the second condition below.

但し、θ［°］は搬送面１１と規制面２０のスロープ２１とが成す角度である。
Ｒ［ｍｍ］は硬貨９０の外径である。
Ｔ［ｍｍ］は規制面２０のスロープ２１の長さである。
Ｈ［ｍｍ］は硬貨９０の厚さ（高さ）である。 (Second condition)
The slope 21 of the regulation surface 20 is a coin 90 in which the angle θ [°] shown in FIG. 5 is in circulation (preferably, a plurality of types of coins in circulation 90, and more preferably all types in circulation. The coin 90) shall have a configuration that satisfies the following formula (2). The grounds for the following formula (2) will be described later.

However, θ [°] is the angle formed by the slope 21 of the transport surface 11 and the regulation surface 20.
R [mm] is the outer diameter of the coin 90.
T [mm] is the length of the slope 21 of the regulation surface 20.
H [mm] is the thickness (height) of the coin 90.

Hereinafter, the grounds for the above-mentioned equations (1) and (2) will be described. If the lateral deviation of the coin 90 during transportation becomes large, the first sensor SN1, which is a diameter sensor, tends to be erroneously detected. Therefore, it is preferable that the coin recognizing device 10 reduces the lateral displacement of the coin 90 during transportation. The above-mentioned equation (1) is for suppressing the lateral deviation of the coin 90 during transportation to a swing width ΔD [mm] or less, and defines the lower limit of the angle θ [°]. Further, when the coin 90 is lifted from the transport surface 11, the first sensor SN1 which is a diameter sensor is likely to be erroneously detected, and the second sensor SN2 which is a material / thickness sensor is also liable to be erroneously detected. Therefore, it is preferable that the coin recognizing device 10 suppresses the lifting of the coin 90. The above-mentioned equation (2) is for suppressing the lifting of the coin 90 on the regulation surface 20 side, and defines the upper limit of the angle θ [°]. The above-mentioned equations (1) and (2) are derived as follows.

(Equation that defines the lower limit of the angle θ)
First, an equation (that is, the above-mentioned equation (1)) that defines the lower limit of the angle θ [°] will be described. The above equation (1) is derived from the relationship between the slope 21 of the regulation surface 20 and the coin 90 shown in FIGS. 4 and 5.

但し、θ［°］は、搬送面１１と規制面２０のスロープ２１とが成す角度（内角）である。
Ｈ［ｍｍ］は、硬貨９０の厚さ（高さ）である。
Ｄ［ｍｍ］は、搬送面１１の一方側（規制面２０側）から硬貨９０までの距離である。 Specifically, from the relationship between the slope 21 of the regulation surface 20 and the coin 90 shown in FIG. 4, the angle θ [°] can be obtained by deriving the following equation (4) from the following equation (3). it can.

However, θ [°] is an angle (internal angle) formed by the slope 21 of the transport surface 11 and the regulation surface 20.
H [mm] is the thickness (height) of the coin 90.
D [mm] is the distance from one side of the transport surface 11 (regulatory surface 20 side) to the coin 90.

When the angle θ [°] is the lower limit value, the coin 90 does not float and comes into close contact with the transport surface 11. Therefore, the formula that defines the lower limit of the angle θ [°] (that is, the above-mentioned formula (1)) defines a state in which the coin 90 is in close contact with the transport surface 11 without rising, as shown in FIG. Become. In addition, ΔH [mm] shown in FIG. 5 represents the swing width in the thickness (height) direction due to the difference in the type of coin 90 (that is, the swing width with respect to the thickness (height) H shown in FIG. 4). .. Further, ΔD [mm] shown in FIG. 5 represents a lateral swing width (that is, a swing width with respect to the distance D shown in FIG. 4) due to a difference in the type of coin 90. Then, referring to the above-mentioned equations (3) and (4), the equation (that is, the above-mentioned equation (1)) that defines the lower limit of the angle θ [°] is the following equation from the above-mentioned equation (3). It can be obtained by deriving (5) and further deriving the following equation (6) from the following equation (5).

The above-mentioned formula (6) is the same as the above-mentioned formula (1). Therefore, the above equation (1) is derived as described above.

(Equation that defines the upper limit of the angle θ)
Next, an equation (that is, the above-mentioned equation (2)) that defines the upper limit of the angle θ [°] will be described. The above equation (2) is derived from the relationship between the slope 21 of the regulation surface 20 and the coin 90 shown in FIGS. 6 and 7.

The closer the angle θ [°] is to the upper limit (that is, the larger the angle θ [°]), the easier it is for the coin 90 to float. Then, as shown in FIG. 6, when the coin 90 is lifted on the regulation surface 20 side and there is a gap 91 between the slope 21 of the regulation surface 20 and the coin 90, the slope 21 is set. The pressing force applied to the coin 90 from the width adjusting arm 15 can be guided in the direction of the transport surface 11. Therefore, in this case, the regulation surface 20 can apply a pressure to the coin 90 in the direction of the transport surface 11. Therefore, the coin recognizing device 10 can suppress the lifting of the coin 90 on the regulation surface 20 side in the state shown in FIG. 6, and the lifted coin 90 is in the state shown in FIG. 4 (coin 90 and the transport surface). It can be returned to the state where it is in close contact with 11. That is, even if the coin 90 may float on the regulation surface 20 side, the coin recognizing device 10 shows the lifted coin 90 in the state shown in FIG. 4 (coin 90 and the transport surface) in the state shown in FIG. It can be returned to the state where it is in close contact with 11.

However, as shown in FIG. 7, when the coin 90 is lifted on the regulation surface 20 side and there is no gap 91 between the slope 21 of the regulation surface 20 and the coin 90, the slope 21 is set. The pressing force applied to the coin 90 from the width adjusting arm 15 cannot be guided in the direction of the transport surface 11. Therefore, in this case, the restricting surface 20 cannot apply pressure to the coin 90 in the direction of the transport surface 11. Therefore, the coin recognizing device 10 cannot suppress the lifting of the coin 90 on the regulation surface 20 side in the state shown in FIG. 7, and the lifted coin 90 is shown in the state shown in FIG. 4 (coin 90 and the transport surface 11). It cannot be returned to the state where it is in close contact with. That is, in the coin recognition device 10, if the coin 90 is lifted on the regulation surface 20 side and the state shown in FIG. 7 is reached, the lifted coin 90 is in the state shown in FIG. 4 (coin 90 and transport surface 11). Cannot be returned to the state of close contact. As a result, when the coin 90 is in the state shown in FIG. 7, the coin 90 is conveyed in a floating state on the regulation surface 20 side. Note that FIG. 7 is a virtual model in which the coin 90 is deformed so that the side surface of the coin 90 abuts on the slope 21 of the regulation surface 20.

Ｒ［ｍｍ］は硬貨９０の外径である。
Ｔ［ｍｍ］は規制面２０のスロープ２１の長さである。
Ｈ［ｍｍ］は硬貨９０の厚さ（高さ）である。 In the virtual model shown in FIG. 7, the angle θ [°] can be obtained by deriving the following equation (8) from the following equation (7).

However, θ [°] is the angle formed by the slope 21 of the transport surface 11 and the regulation surface 20.
R [mm] is the outer diameter of the coin 90.
T [mm] is the length of the slope 21 of the regulation surface 20.
H [mm] is the thickness (height) of the coin 90.

Ｒ［ｍｍ］は硬貨９０の外径である。

Ｈ［ｍｍ］は硬貨９０の厚さ（高さ）である。 However, the above-mentioned equation (8) is an equation derived from the virtual model shown in FIG. 7, which cannot suppress the floating of the coin 90 on the regulation surface 20 side. In order to suppress the lifting of the coin 90 on the regulation surface 20 side, the value of the angle θ is smaller than the right side of the above equation (8). Therefore, the equation (that is, the above-mentioned equation (2)) that defines the upper limit of the angle θ [°] is as shown in the following equation (9).

However, θ [°] is the angle formed by the slope 21 of the transport surface 11 and the regulation surface 20.
