[0008] Hereinafter, embodiments of the present invention will be described with reference to the illustrations. In the following description, the same elements are denoted by the same symbols. Their names and functions are also the same. Therefore, detailed descriptions of them will not be repeated. <Overall Structure of Coin Processing Device 100>

[0009] First, the overall structure of the coin processing device 100 of this embodiment will be explained. Figure 1 is an external view of the coin processing device 100 of this embodiment. Referring to Figure 1, the coin processing device 100 is composed of a roughly rectangular frame 101, with a coin inlet 102 at the top and a coin outlet 103 at the bottom.

[0010] Figure 2 is a side cross-sectional view showing the overall internal structure of the coin processing apparatus 100 according to this embodiment. Referring to Figure 2, the coin processing apparatus 100 has a coin identification and sorting unit 105 at the top for sorting and distributing coins according to type; a coin dispensing unit 150 in the middle for accumulating and dispensing coins according to each type; and a control unit 190 at the bottom. In this embodiment, the coin dispensing unit 150 is composed of an upper dispensing unit 151 for four types of coins and a lower dispensing unit 152 for four types of coins. The control unit 190 is equipped with a microcomputer 191 for controlling various parts of the coin processing apparatus 100, or other communication interfaces. The microcomputer 191 includes, for example, a CPU or various types of memory.

[0011] Figure 3 is a plan view of the coin recognition and sorting unit 105 related to this embodiment. Referring to Figure 3, the inserted coins are sequentially sent one by one to the sorting unit 120 via the receiving unit 110. The sorting unit 120 identifies the type of coin according to each coin and conveys the coin to the following paths: a rejection conveying path 1510 formed on the outside of the sorting unit; a first conveying path 1511 formed on the outside of the sorting unit; a second conveying path 1512 formed on the inside of the sorting unit; a third conveying path 1513 formed on the outside of the sorting unit; a fourth conveying path 1514 formed on the inside of the sorting unit; a fifth conveying path 1515 formed on the outside of the sorting unit; a sixth conveying path 1516 formed on the inside of the sorting unit; a seventh conveying path 1517 formed on the outside of the sorting unit; an eighth conveying path 1518 formed on the inside of the sorting unit; and an overflow conveying path 1519 formed on the outside of the sorting unit.

[0012] Figure 4 shows the overall internal structure of the coin processing apparatus 100 according to this embodiment, and in particular shows a front cross-sectional view of the process of sorting and collecting the inserted coins. Figure 5 shows the overall internal structure of the coin processing apparatus 100 according to this embodiment, and in particular shows a side cross-sectional view of the process of sorting and collecting the inserted coins. Referring to Figures 4 and 5, coins sent to the rejection conveying passage 1510 are at the right end when viewed from the front and move downwards along the front end when viewed from the side, and are rejected from the coin discharge outlet 103. Coins sent to the overflow conveying passage 1519 are at the left end when viewed from the front and move downwards along the front end when viewed from the side, and are sent to the container located below the coin processing apparatus 100. Coins sent to the first conveying passage 1511, the third conveying passage 1513, the fifth conveying passage 1515, and the seventh conveying passage 1517 outside the sorting section 120 are accumulated in a predetermined receiving section of the upper dispensing section 151 according to each coin type. The coins sent to the second transport path 1512, the fourth transport path 1514, the sixth transport path 1516, and the eighth transport path 1518 inside the sorting section 120 are stored in the predetermined receiving section of the lower distribution section 152 according to each coin type.

[0013] Figure 6 shows the overall internal structure of the coin processing apparatus 100 according to this embodiment, and in particular shows a front cross-sectional view of the process of issuing or collecting coins in a collection box (not shown). Figure 7 shows the overall internal structure of the coin processing apparatus 100 according to this embodiment, and in particular shows a side cross-sectional view of the process of issuing or collecting coins. Referring to Figures 6 and 7, coins accumulated from the outside of the sorting section 120 via the first, third, fifth, and seventh passages are sent forward along the upper dispensing section 151 and descended according to the command from the control section 190, discharged from the discharge port 103, and sent to the collection box from the collection port 104. Coins accumulated from the lower side of the sorting section 120 via the second, fourth, sixth, and eighth passages are sent forward along the lower dispensing section 152 and descended according to the command from the control section 190, discharged from the discharge port 103, and sent to the collection box from the collection port 104. <Composition of Coin Recognition and Sorting Unit 105>

[0014] Next, the configuration of the coin identification and sorting unit 105 at the upper part of the coin processing device 100 will be explained. Referring to Figures 8 and 9, the coin identification and sorting unit 105 mainly includes a receiving unit 110 and a sorting unit 120. The receiving unit 110 is located on the front side of the coin processing device 100, that is, the front part, and is used to send the coins inserted one by one from the coin insertion slot 102 to the sorting unit 120. The sorting unit 120 is located on the back side of the coin processing device 100, that is, the rear part, and is used to identify the type of coin sent from the receiving unit 110 and send it to the transport path according to the type. <Composition of Receiving Unit 110>

[0015] The receiving section 110 will now be described. Referring to Figures 8 to 10, the receiving section 110 is provided with a circular base 111 and a cylindrical sidewall 112. An introducing rotating disk 113 is disposed on the top of the base 111. A plurality of coin insertion holes 113X are formed on the introducing rotating disk 113. In this embodiment, three holes 113X are formed. That is, the holes 113X are formed at 120° intervals around the center of the drive shaft. The introducing rotating disk 113, driven by a motor (not shown), pushes the coins inserted into the holes 113X one by one from the discharge port at the rear of the sidewall 112 outward and into the sorting section 120.

[0016] More specifically, when the coin, in conjunction with the operation of the hole 113X in the rotating disk 113, rotates clockwise in plan view, it is squeezed backward along the arrangement direction of the guide pins 114, 114, 114 when it collides with them, that is, squeezed outward toward the outside of the sidewall 112. Furthermore, the guide pins 114, 114, 114 are configured as shown in Figure 11, with potential energy applied from above.

[0017] Here, we will explain the mechanism for feeding coins one by one from the receiving unit 110 to the sorting unit 120. Regarding the coin handling apparatus 100 of this embodiment, it is equipped with a mechanism that, even when multiple coins are stacked in one hole 113X, feeds only one coin from the discharge port 113Y of the receiving unit 110 directly from the rotating disk 113 to the coin discharge, even when the coin is being transported directly from one hole 113X. The configuration of this mechanism will be explained below.

[0018] Referring to Figures 10 to 13, the receiving part 110 in this embodiment is provided with a circular base 111 and a cylindrical sidewall 112. An introduction rotating disk 113 is disposed on the top of the base 111. A plurality of coin insertion holes 113X are formed on the introduction rotating disk 113. In this embodiment, three holes 113X are formed. That is, holes 113X are formed every 120° around the drive shaft.

[0019] Secondly, for each of the three holes 113X, a discharge port 113Y for one coin weight is formed on the outer rear side. A scraper 115 is provided on each of the discharge ports 113Y. The scraper 115 is configured to slide vertically and can be applied downwards by a spring or the like. In this embodiment, the scraper 115 is configured such that it is pushed upwards until it reaches a position only +α mm higher than the expected thickness of the coin C1. Furthermore, when the scraper 115 is closed from the bottom, a gap of approximately 1 mm to 1.5 mm is formed between the lower end of the scraper 115 and the base 111.

[0020] In this embodiment, in plan view, the front end of the scraper 115 is formed as a curved surface with the same curvature as the inner circumference of the hole 113X into which the rotating disk 113 is introduced. That is, in plan view, the hole 113X and the scraper 115 constitute a smooth circle.

[0021] Secondly, particularly in this embodiment, a base guide 119 is provided below the introduced rotating disk 113. More specifically, below the side wall 112, along the periphery of the circular base 111, ribs 119X are provided, vertically erected from the base guide 119. The ribs 119X can be objects of a continuous shape around approximately the entire periphery of the base 111, or they can be multiple protrusions of other shapes.

[0022] Rib 119X is not located in the receiving and dispatching area of ​​coin C1 between the sorting section 120 and the sorting section 120. That is, outside the receiving and dispatching area between the sorting section 120 and the sorting section 120, rib 119X protrudes upward near the outer periphery of the inner side of holes 113X, 113X, 113X.

[0023] In this way, the outer portion of one or more coins entering holes 113X, 113X, and 113X will remain floating above the base 111. As a result, the possibility that even if two or more coins enter hole 113X, they will lie completely horizontally on top of the base 111 will be reduced, and the possibility that two or more coins will be discharged from the discharge outlet 113Y will also be reduced.

[0024] As described above, regarding the receiving section 110 of this embodiment, because the rotating disk 113 is rotated, the coins C1 that fall into the hole 113X are pushed one by one from the discharge port 113Y of the hole 113X and the discharge port 112X at the rear of the side wall 112 while being pushed by the scraper 115 or the side of the hole 113X, and are sent to the sorting section 120.

[0025] Secondly, as shown in Figure 14, in this embodiment, the height of the portion protruding above the surface of the base 111 of the guide pins 114, 114, 114 is set to be lower than the thinnest coin of the device object. For example, about 1 mm.

[0026] Furthermore, since the height (gap) of the coin outlet 113Y from the base 111 of the rotating disk 113 is the thickness of the coin with the maximum thickness + α mm, when a certain type of coin with a difference of about twice the maximum thickness and minimum thinness is inserted, there is a possibility that they will be transported in an overlapping manner. However, since the height of the guide pins 114, 114... for rolling out is set to be lower than the coin with the minimum thinness, even if two thin coins overlap in the hole 113X of the rotating disk 113, the upper coin C2 will not be pushed back to the inside of the side wall 112 and the hole 113X by the guide pins 114, 114....

[0027] Thus, as shown in Figure 15, even if two thin coins overlap within the hole 113X of the rotating disk 113, only the bottom coin C1 is pushed upwards and backwards by the guide pins 114, 114, 114, along the inclined surface 115X of the scraper 115. That is, the scraper 115 is lifted upwards against the applied force. On the other hand, the upper coin C2 does not contact the guide pins 114 and is stopped by the scraper 115, thus being pushed back to the inside of the side wall 112 or the hole 113X. As a result, only the bottom coin C1 is discharged into the sorting section 120 through the discharge port 113Y and the discharge port 112X of the side wall 112. <The Composition of the Sorting Section 120>

[0028] Next, the sorting unit 120 will be described. Referring to Figures 8, 9, and 16, the sorting unit 120 includes a circular base 121 and a side wall 122 on the outer periphery of the base 121. A conveying rotating body 123 is disposed above the base 121. The conveying rotating body 123 has a plurality of conveying pins 123X, 123X... for pushing the coins forward from the rear. In this embodiment, five conveying pins 123X, 123X... are formed. That is, conveying pins 123X, 123X... are installed at 72° intervals around the axis of the conveying rotating body 123. The conveying rotating body 123 is driven by a drive motor 106, causing the coins to rotate counterclockwise one by one in planar view and slide in the passage between the side wall 122 and the conveying guide 139. That is, in this embodiment, the sorting unit 120 can simultaneously transport up to 5 coins to the transport path.

[0029] More specifically, the front end of the side wall 122 of the sorting section 120 is opened, that is, the wall side of the receiving section 110 is opened, and a coin is fed into the receiving section 110. The received coin is pushed by the conveying pin 123X and moves to the right along the side wall 122 and the conveying guide 139. That is, in plan view, the coin moves forward counterclockwise around the circular base 121.

[0030] The identification unit 130 uses a displacement sensor or a magnetic sensor to determine the authenticity of coins delivered via the conveying pin 123X and to identify the type of coin. The configuration of the identification unit 130 in this embodiment will be described below.

[0031] Referring to Figures 16, 17, and 18, the identification unit 130 includes: a horizontal displacement sensor 131, a surface displacement sensor 132, an internal displacement sensor 133, and a magnetic sensor 134.

[0032] The horizontal displacement sensor 131 is used to measure the width and diameter of the coin C1 sent from the receiving unit 110. More specifically, as shown in FIG17, the horizontal displacement sensor 131 is directly or indirectly connected to the horizontal detection lever 131X. The horizontal detection lever 131X is configured to rotate in the horizontal direction and apply potential energy to the side wall 122. When the coin C1 touches the detection lever 131X, the detection lever 131X is pushed inward, and the width or diameter of the coin C1 is determined by detecting the amount by which the horizontal displacement sensor 131 detects the horizontal detection lever 131X being pushed inward.

[0033] Surface displacement sensor 132 is an object used to measure the height of the surface side of coin C1. More specifically, as shown in Figures 18 and 19, surface displacement sensor 132 is directly or indirectly connected to surface detection rod 132X. Surface detection rod 132X is configured to rotate vertically and apply potential energy downwards. When coin C1 contacts surface detection rod 132X, surface detection rod 132X is pushed upwards, and the change in the height (shift) of the surface of coin C1 is determined by detecting the amount by which surface detection rod 132X is pushed upwards.

[0034] The internal displacement sensor 133 is an object used to measure the height of the inside of the coin C1. More specifically, as shown in Figures 18 and 19, the internal displacement sensor 133 is directly or indirectly connected to the internal detection rod 133X. The internal detection rod 133X is configured to rotate vertically and apply potential energy to the upward conveying surface. When the coin C1 contacts the internal detection rod 133X, the internal detection rod 133X is pushed downward, and the internal displacement sensor 133 detects the amount of downward push of the internal detection rod 133X to determine the change (shift) in the height of the inside of the coin C1.

[0035] The magnetic sensor 134 is an object that uses a coil to identify the material of the coin C1. In this embodiment, as shown in FIG18, the magnetic sensor 134 is disposed below the conveying surface.

[0036] The horizontal displacement sensor 131 of the identification unit 130 sends the horizontal displacement amount to the microcomputer 191 of the control unit 190. The microcomputer 191 identifies the diameter of the coin C1 based on the change (shift) of this amount.

[0037] The surface displacement sensor 132 of the identification unit 130 sends the upward displacement amount to the microcomputer 191 of the control unit 190. The microcomputer 191 obtains the change in height of the surface side of the coin C1 based on the change in this amount of displacement, as shown in FIG20.

[0038] The displacement sensor 133 inside the recognition unit 130 sends the downward displacement amount to the microcomputer 191 of the control unit 190. The microcomputer 191 obtains the change in height of the inside of the coin C1 based on the change in displacement amount, as shown in FIG20.

[0039] The magnetic sensor 134 of the identification unit 130 sends the magnetic change to the microcomputer 191 of the control unit 190. The microcomputer 191 identifies the material of the coin C1 based on the change.

[0040] In this embodiment, the microcomputer 191 is used to memorize: the diameter of each type of coin, the change (shift) of the surface height, the change (shift) of the interior height, and the material. Secondly, the microcomputer 191 is used to identify: the type of coin that matches the diameter, the change (shift) of the surface height, the change (shift) of the interior height, and the material of the coin C1 measured. In this embodiment, since the type of coin C1 is identified based on four factors, the coin can be identified more accurately.

[0041] In this embodiment, the memory of the microcomputer 191 is used to remember the location of each transport path or storage box for each type of coin. Based on the judgment or identification result, the microcomputer 191 moves the coin C1 that fails to be identified to the rejection path, and moves the coin C1 that can be identified to the corresponding transport path or storage location for that type.

[0042] For example, as shown in FIG3, the coin processing apparatus 100 of this embodiment is used to transport four types of coins to the outside of the circular sorting section and to transport four types of coins to the downward side. Conclusion
