DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the following description, the same components are denoted by the same reference numerals. Their names and functions are also the same. Therefore, detailed description thereof will not be repeated. <Overall configuration of the coin handling device 100>

[0009] First, the overall configuration of a coin processing device 100 according to this embodiment will be described. Fig. 1 is an external view of the coin processing device 100 according to this embodiment. With reference to Fig. 1, the coin processing device 100 is composed of a substantially rectangular parallelepiped housing 101, with a coin insertion port 102 provided at the top and a coin ejection port 103 provided at the bottom.

[0010] Fig. 2 is a side cross-sectional view showing the overall internal structure of the coin processing device 100 according to this embodiment. With reference to Fig. 2, the coin processing device 100 is provided with a coin identifying and sorting unit 105 for sorting and sending out coins by type at its upper portion, a coin dispensing unit 150 for storing and dispensing coins by type at its middle portion, and a control unit 190 at its lower portion. In this embodiment, the coin dispensing unit 150 is composed of an upper dispensing unit 151 for four denominations and a lower dispensing unit 152 for four denominations. The control unit 190 is provided with a microcomputer 191 for controlling each unit of the coin processing device 100, other communication interfaces, and the like. The microcomputer 191 includes, for example, a CPU and various memories.

[0011] 3 is a plan view of the coin identifying and sorting unit 105 according to this embodiment. Referring to FIG. 3, a plurality of inserted coins are sent one by one in order to the sorting unit 120 by the handling unit 110. The sorting section 120 identifies the type of coin for each coin and sends it to a reject conveying path 1510 formed outside the sorting section, a first conveying path 1511 formed outside the sorting section, a second conveying path 1512 formed inside the sorting section, a third conveying path 1513 formed outside the sorting section, a fourth conveying path 1514 formed inside the sorting section, a fifth conveying path 1515 formed outside the sorting section, a sixth conveying path 1516 formed inside the sorting section, a seventh conveying path 1517 formed outside the sorting section, an eighth conveying path 1518 formed inside the sorting section, or an overflow conveying path 1519 formed outside the sorting section.

[0012] FIG. 4 is a front cross-sectional view showing the overall internal structure of the coin processing device 100 according to the present embodiment, and in particular, a flow when the inserted coins are sorted and stored. FIG. 5 is a side cross-sectional view showing the overall internal structure of the coin processing device 100 according to the present embodiment, and in particular, a flow when the inserted coins are sorted and stored. With reference to FIG. 4 and FIG. 5, a coin sent to the reject conveying path 1510 is at the right end in a front view, and moves downward at the front end in a side view, and is rejected from the coin discharge port 103. A coin sent to the overflow conveying path 1519 is at the left end in a front view, and moves downward at the front end in a side view, and is sent to a container disposed below the coin processing device 100. The coins sent to the first conveying path 1511, the third conveying path 1513, the fifth conveying path 1515, and the seventh conveying path 1517 outside the sorting unit 120 are accumulated in a predetermined storage unit of the upper dispensing unit 151 for each denomination. Coins sent to the second conveying path 1512, the fourth conveying path 1514, the sixth conveying path 1516, and the eighth conveying path 1518 inside the sorting section 120 are accumulated in designated storage sections of the lower dispensing section 152 by denomination.

[0013] FIG. 6 is a front cross-sectional view showing the overall internal structure of the coin processing device 100 according to this embodiment, and in particular the flow when coins are dispensed or collected in a collection box (not shown). FIG. 7 is a side cross-sectional view showing the overall internal structure of the coin processing device 100 according to this embodiment, and in particular the flow when coins are dispensed or collected. With reference to FIG. 6 and FIG. 7, coins accumulated from the outside of the sorting unit 120 via the first path, the third path, the fifth path, and the seventh path are sent forward through the upper dispensing unit 151 and then descended to be discharged from the discharge port 103 or sent from the collection port 104 to the collection box in accordance with a command from the control unit 190. Coins accumulated from the lower side of the sorting unit 120 via the second path, the fourth path, the sixth path, and the eighth path are sent forward through the lower dispensing unit 152 and then descended to be discharged from the discharge port 103 or sent from the collection port 104 to the collection box in accordance with a command from the control unit 190. <Configuration of the coin identification and sorting unit 105>

[0014] Next, the configuration of the coin identifying and sorting unit 105 at the top of the coin processing device 100 will be described. With reference to Fig. 8 and Fig. 9, the coin identifying and sorting unit 105 mainly includes a sorting unit 110 and a sorting unit 120. The sorting unit 110 is disposed on the front side, i.e., the front part, of the coin processing device 100, and is for sending coins inserted one after another from the coin insertion slot 102 to the sorting unit 120 one by one. The sorting unit 120 is disposed on the back side, i.e., the rear part, of the coin processing device 100, and is for identifying the type of coin sent from the sorting unit 110 and sending it to a transport path according to its type. <Configuration of the separation unit 110>

[0015] The separating unit 110 will be described below. With reference to Figs. 8 to 10, the separating unit 110 is provided with a circular base 111 and a cylindrical side wall 112. An input turntable 113 is disposed on the upper surface of the base 111. The input turntable 113 is formed with a plurality of holes 113X into which coins fit. In this embodiment, three holes 113X are formed. That is, the holes 113X are formed at 120° intervals around the drive shaft. The input turntable 113 is driven by a motor (not shown) to push the coins that fit into the holes 113X outward one by one from a discharge port at the rear of the side wall 112 and send them to the sorting unit 120.

[0016] More specifically, the coin rotates clockwise in a plan view in accordance with the movement of the hole 113X of the intake turntable 113, and when the coin hits the guide pins 114, 114, 114, it is pushed backward along the arrangement of the guide pins 114, 114, 114, that is, toward the outside of the side wall 112. The guide pins 114, 114, 114 are configured as shown in Fig. 11 and are biased upward.

[0017] Here, a mechanism for sending coins one by one from the handling unit 110 to the sorting unit 120 will be described. The coin processing device 100 according to this embodiment is equipped with a mechanism for outputting only one coin from one hole 113X through the discharge port 113Y of the handling unit 110, even when multiple coins remain stacked in one hole 113X and the coins start to be transported by the intake turntable 113. This configuration will be described below.

[0018] 10 to 13, the handling unit 110 according to this embodiment is provided with a circular base 111 and a cylindrical side wall 112. An input turntable 113 is disposed on the upper surface of the base 111. The input turntable 113 is formed with a plurality of holes 113X into which coins fit. In this embodiment, three holes 113X are formed. That is, the holes 113X are formed at 120° intervals around the drive shaft.

[0019] Each of the three holes 113X has an outlet 113Y for one coin formed at an oblique rearward position closer to the outside. A scraper 115 is provided in each of the outlets 113Y. The scraper 115 is configured to be slidable in the vertical direction and is biased downward by a spring or the like. The scraper 115 according to this embodiment is configured to stop at a position that is +α mm higher than the assumed thickness of the coin C1 when pushed upward. Note that the scraper 115 is configured to leave a gap of about 1 mm to 1.5 mm between the lower end of the scraper 115 and the base 111 when the scraper 115 is closed downward.

[0020] In this embodiment, in plan view, the surface at the tip of the scraper 115 is formed into a curved shape with the same curvature as the inner circumference of the hole 113X of the take-in turntable 113. In other words, in plan view, the hole 113X and the scraper 115 form one smooth circle.

[0021] Particularly in this embodiment, a base guide 119 is disposed below the intake turntable 113. More specifically, a rib 119X is provided below the side wall 112, extending upright from the base guide 119 around the periphery of the circular base 111. The rib 119X may be of a shape that continues around substantially the entire periphery of the base 111, or may be a plurality of protrusions of another shape.

[0022] The rib 119X is not provided in the area for transferring the coin C1 to the sorting unit 120. In other words, the rib 119X protrudes upward near the outer periphery of the inside of the holes 113X, 113X, and 113X in a place other than the area for transferring the coin C1 to the sorting unit 120.

[0023] This keeps one or more coins that have entered the holes 113X, 113X, 113X in a state where their outer portions are raised above the base 111. As a result, it is possible to reduce the possibility that two or more coins that have entered the holes 113X will both lie completely on the upper surface of the base 111, and it is possible to reduce the possibility that two or more coins will be discharged from the discharge port 113Y at once.

[0024] As described above, in the sorting section 110 of this embodiment, as the intake turntable 113 rotates, the coins C1 that fall into the hole 113X are pushed by the scraper 115 and the side of the hole 113X, and are pushed outward one by one from the discharge outlet 113Y of the hole 113X and the discharge outlet 112X at the rear of the side wall 112, and are sent to the sorting section 120.

[0025] 14, in this embodiment, the height of the guide pins 114, 114, 114 protruding above the surface of the base 111 is set to be lower than the thinnest coin that the device is intended for, for example, about 1 mm.

[0026] In addition, because the height (gap) of the coin discharge port 113Y from the base 111 of the intake turntable 113 is the thickness of the target maximum coin +α mm, when the smallest coin of a type whose maximum thickness is about twice the minimum thickness is inserted, they may be transported overlapping each other. However, because the height of the feeding guide pins 114, 114... is set lower than the target minimum thinnest coin, even if two thin coins are stacked in the hole 113X of the intake turntable 113, the upper coin C2 is pushed back into the side wall 112 or the inside of the hole 113X without colliding with the guide pins 114, 114...

[0027] As a result, even if two thin coins are stacked in the hole 113X of the take-in turntable 113 as shown in FIG. 15, only the bottom coin C1 is pushed by the guide pins 114, 114, 114 and pushes the inclined surface 115X of the scraper 115 upward and rearward. That is, the scraper 115 is lifted upward against the biasing force. On the other hand, the upper coin C2 is stopped by the scraper 115 without colliding with the guide pin 114 and is pushed back to the inside of the side wall 112 and the hole 113X. As a result, only the bottom coin C1 is discharged to the sorting section 120 through the discharge port 113Y and the discharge port 112X of the side wall 112. <Configuration of the sorting unit 120>

[0028] Next, the sorting unit 120 will be described. With reference to Figs. 8, 9, and 16, the sorting unit 120 is provided with a circular base 121 and a side wall 122 provided on the outer periphery of the base 121. A conveying rotor 123 is disposed above the base 121. A plurality of conveying pins 123X, 123X... are formed on the conveying rotor 123 for pushing coins from the rear and advancing them. In this embodiment, five conveying pins 123X, 123X... are formed. That is, the conveying pins 123X, 123X... are attached at 72° intervals around the axis of the conveying rotor 123. The conveying rotor 123 is driven by the drive motor 106 to slide the coins one by one in a counterclockwise direction in a plan view through a passage between the side wall 122 and the conveying guide 139. That is, in this embodiment, the sorting unit 120 can simultaneously transport a maximum of five coins and send them out onto the transport path.

[0029] More specifically, the front end of the side wall 122 of the sorting unit 120, i.e., the wall surface on the sorting unit 110 side, is opened, and coins are sent in from the sorting unit 110. The received coins are pushed by the transport pins 123X and move rightward between the side wall 122 and the transport guide 139. That is, in a plan view, the coins move counterclockwise around the circular base 121.

[0030] The recognition unit 130 uses a displacement sensor, a magnetic sensor, etc. to determine whether the coins sent by the transport pins 123X are genuine or counterfeit, and to identify the type of coin. The configuration of the recognition unit 130 according to this embodiment will be described below.

[0031] 16, 17 and 18, the recognition unit 130 includes a horizontal displacement sensor 131, a front surface displacement sensor 132, a rear surface displacement sensor 133, and a magnetic sensor 134.

[0032] The horizontal displacement sensor 131 is for measuring the width and diameter of the coin C1 sent from the handling section 110. More specifically, as shown in Fig. 17, a horizontal detection lever 131X is directly or indirectly connected to the horizontal displacement sensor 131. The horizontal detection lever 131X is configured to be rotatable in the horizontal direction, and is biased toward the side wall 122. When the coin C1 comes into contact with the detection lever 1311, the detection lever 131X is pushed inward, and the horizontal displacement sensor 131 detects the amount by which the horizontal detection lever 131X is pushed in, thereby measuring the width and diameter of the coin C1.

[0033] The surface displacement sensor 132 is for measuring the height of the surface side of the coin C1. More specifically, as shown in Figs. 18 and 19, a surface detection lever 132X is directly or indirectly connected to the surface displacement sensor 132. The surface detection lever 132X is configured to be rotatable in the vertical direction, and is biased toward the conveying surface below. When the coin C1 comes into contact with the surface detection lever 132X, the surface detection lever 132X is pushed upward, and the surface displacement sensor 132 detects the amount by which the surface detection lever 132X is pushed up, thereby measuring the transition in the height of the surface of the coin C1.

[0034] The back surface displacement sensor 133 is for measuring the height of the back surface side of the coin C1. More specifically, as shown in Figs. 18 and 19, a back surface detection lever 133X is directly or indirectly connected to the back surface displacement sensor 133. The back surface detection lever 133X is configured to be rotatable in the vertical direction and is biased toward the upper conveying surface. When the coin C1 comes into contact with the back surface detection lever 133X, the back surface detection lever 133X is pushed downward, and the back surface displacement sensor 133 detects the amount by which the back surface detection lever 133X is pushed down, thereby measuring the transition in the height of the back surface of the coin C1.

[0035] The magnetic sensor 134 uses a coil to identify the material of the coin C1. In this embodiment, as shown in Fig. 18, the magnetic sensor 134 is disposed below the conveyance surface.

[0036] The horizontal displacement sensor 131 of the recognition unit 130 sends the amount of horizontal displacement to the microcomputer 191 of the control unit 190. The microcomputer 191 identifies the diameter of the coin C1 based on the transition of the amount of change.

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

[0038] The back surface displacement sensor 133 of the recognition unit 130 sends the amount of downward displacement to the microcomputer 191 of the control unit 190. Based on the change in the amount of change, the microcomputer 191 obtains the change in the height of the back surface side of the coin C1, as shown in FIG.

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

[0040] The microcomputer 191 according to this embodiment stores the diameter, the change in the height of the front surface, the change in the height of the back surface, and the material for each type of coin. The microcomputer 191 then identifies the type of coin that matches the diameter of the currently measured coin C1, the change in the height of the front surface of the coin C1, the change in the height of the back surface of the coin C1, and the material of the coin C1. In this embodiment, the type of coin C1 is identified based on the four elements, making it possible to more accurately identify the coin.

[0041] In this embodiment, the memory of the microcomputer 191 stores the transport path or the position of the storage case for each type of coin. Based on the judgment result or the identification result, the microcomputer 191 transports the coin C1 that has failed to be identified to a rejection path, and transports the coin C1 whose type has been identified to a transport path or storage location according to the type.

[0042] For example, as shown in FIG. 3, the coin processing device 100 according to the present embodiment transports four types of coins toward the outside of a circular sorting unit, and transports four types of coins toward the lower side. <Summary>
