[0008] [First embodiment] <Overall configuration of coin handling device 100> 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. Referring to Fig. 1, the coin processing device 100 is made up of a substantially rectangular parallelepiped housing 101, with a coin insertion slot 102 provided on the top surface and a coin ejection slot (described later) provided on the front surface.

[0009] Fig. 2 is a side cross-sectional view showing the overall internal structure of the coin processing device 100 in a state where the bucket 160 according to this embodiment is raised. Fig. 3 is a side cross-sectional view showing the overall internal structure of the coin processing device 100 in a state where the bucket 160 according to this embodiment is lowered. With reference to Figs. 2 and 3, the coin processing device 100 is provided at its upper part with an identifying and sorting unit 109 for feeding out coins 10 one by one, identifying them, and sorting and feeding them out by type. A storing and dispensing unit 150 is provided at its lower part for storing and dispensing coins 10 by type.

[0010] In this embodiment, the storing and dispensing section 150 includes an upper storage unit 151 for four denominations and a lower storage unit 152 for four denominations. In this embodiment, the upper storage unit 151 and the lower storage unit 152 can be removed with the front wall of the coin processing device 100 removed.

[0011] The coin processing device 100 according to this embodiment is provided with a control unit 190 at the lower end of the identifying and sorting unit 109. The control unit 190 includes a microcomputer and various communication interfaces for controlling each unit of the coin processing device 100. The microcomputer includes a CPU, various memories, and the like.

[0012] FIG. 4 is a perspective view of the identifying and sorting unit 109 according to this embodiment with the upper cover 101A removed. FIG. 5 is a plan view of the identifying and sorting unit 109 according to this embodiment with the upper cover 101A removed. Referring to FIGS. 4 and 5, the inserted coins 10 are sent one by one to the sorting unit 120 by the handling unit 110. The sorting unit 120 identifies the type of each coin 10 using the recognition unit 1330, and sends the coin 10 to a first conveying path 1311 formed outside the sorting unit 120, a second conveying path 1312 formed inside the sorting unit 120, a third conveying path 1313 formed outside the sorting unit 120, a fourth conveying path 1314 formed inside the sorting unit 120, or a fifth conveying path 1315 formed outside the sorting unit 120. The waste paper is sent to the conveying path 1315 formed inside the sorting section 120, to the sixth conveying path 1316 formed inside the sorting section 120, to the seventh conveying path 1317 formed outside the sorting section 120, to the eighth conveying path 1318 formed inside the sorting section 120, to the overflow conveying path 1319 formed outside the sorting section 120, or to the reject conveying path 1320 formed outside the sorting section 120.

[0013] 2 to 5, coins 10 sent to the first conveying path 1311, the third conveying path 1313, the fifth conveying path 1315, and the seventh conveying path 1317 outside the sorting section 120 are accumulated in predetermined storage spaces of the lower storage unit 152 according to their denominations. More specifically, coins 10 sent to the first conveying path 1311 are sent to the rightmost storage space of the lower storage unit 152 when viewed from the front. Coins 10 sent to the third conveying path 1313 are sent to the second storage space from the right of the lower storage unit 152. Coins 10 sent to the fifth conveying path 1315 are sent to the second storage space from the left of the lower storage unit 152. Coins 10 sent to the seventh conveying path 1317 are sent to the leftmost storage space of the lower storage unit 152.

[0014] Furthermore, coins 10 sent to the second conveying path 1312, fourth conveying path 1314, sixth conveying path 1316, and eighth conveying path 1318 inside the sorting section 120 are accumulated in predetermined storage spaces of the upper storage unit 151 according to their denominations. More specifically, coins 10 sent to the second conveying path 1312 are sent to the rightmost storage space of the upper storage unit 151 when viewed from the front. Coins 10 sent to the fourth conveying path 1314 are sent to the second storage space from the right of the upper storage unit 151. Coins 10 sent to the sixth conveying path 1316 are sent to the second storage space from the left of the upper storage unit 151. Coins 10 sent to the eighth conveying path 1318 are sent to the leftmost storage space of the upper storage unit 151.

[0015] FIG. 6 is a left side cross-sectional view of the front part of the coin processing device 100 according to this embodiment with the bucket 160 in a lowered state. FIG. 7 is a front perspective view of the coin processing device 100 showing the bucket 160 in a lowered state. Note that FIG. 7 shows a state in which the bucket cover 103 and the discharge tray 165 have been removed for the sake of explanation. FIG. 8 is a left side cross-sectional view of the front part of the coin processing device 100 with the bucket 160 in a raised state according to this embodiment. FIG. 9 is a front perspective view of the coin processing device 100 showing the bucket 160 in a raised state. Note that FIG. 9 shows a state in which the bucket cover 103 and the discharge tray 165 have been removed for the sake of explanation. FIG. 10 is also a front perspective view of the coin processing device 100 showing the bucket 160 in a raised state. However, in FIG. 10, the discharge tray 165 is illustrated for the sake of explanation.

[0016] 6 and 7, in the coin processing device 100 according to this embodiment, when dispensing coins 10, the bucket 160 is lowered to the lower end in accordance with a command from the control unit 190. Then, in accordance with the command from the control unit 190, a specified number of coins 10 stocked in each storage space are discharged forward and discharged by the bucket 160 onto the discharge tray 165.

[0017] More specifically, the coins 10 accumulated in the upper storage unit 151 are sent forward by a conveyor belt driven in accordance with instructions from the control unit 190, and fall onto the upper surface of the bucket 160. Similarly, the coins 10 accumulated in the lower storage unit 152 are sent forward by a conveyor belt 154 driven in accordance with instructions from the control unit 190, and fall onto the upper surface of the bucket 160.

[0018] As shown in FIG. 1, the front of the lower part of the housing 101 and the right and left side faces of the front part of the housing 101 are covered with a plastic bucket cover 103. As shown in FIGS. 8 to 10, the bucket 160 is configured so that coins 10 are held by the bucket 160 main body and the inner surface of the bucket cover 103 and are lifted up to the discharge tray 165. More specifically, the bucket 160 is mainly configured by an inclined surface 160X that is low in the front and high in the rear. The coins 10 are held by the inclined surface 160X and the back surface of the bucket cover 103 of the coin processing device 100. More specifically, coins 10 discharged from the upper storage unit 151 and the lower storage unit 152 are held by the inclined surface 160X of the bucket 160, the back surface of the front portion of the housing 101 which forms the outer surface of the coin processing device 100, the left surface of the front part of the right side of the housing 101 of the coin processing device 100, and the right surface of the front part of the left side of the housing 101 of the coin processing device 100.

[0019] The bucket cover 103 is opened above the rear of the discharge tray 165. The bucket 160 rises to the opening in accordance with an instruction from the control unit 190. That is, it rises to a position above the rear of the discharge tray 165. As a result, the coins 10 on the bucket 160 slide down toward the front along the inclined surface 160X. That is, they slide down from the opening of the bucket cover 103 to the discharge tray 165.

[0020] 11 is an enlarged view showing the structure around the bucket 160 according to this embodiment when the bucket 160 is raised. In this embodiment, referring to FIGS. 5 and 11, coins that have failed recognition are sent to the reject conveying path 1320 at the left end of the front of the sorting unit 120 and slide down toward the front and downward. The coin then slides down the upper surface of the inclined surface 160X of the bucket 160, and slides down from above the bucket cover 103 into the discharge tray 165. It is preferable that the inclination of the bottom surface of the reject conveying path 1320 and the inclination of the inclined surface 160X of the bucket 160 are the same angle.

[0021] 6 and 8, in this embodiment, a coin insertion slot 102 is provided above the bucket 160. An opening / closing shutter 104 is provided in the coin insertion slot 102. In addition, above the bucket 160 and below the opening / closing shutter 104, an inclined surface 105 having the same size as the bucket 160 is formed.

[0022] When coins 10 are to be accepted, that is, when coins 10 are to be accepted and sorted or stored, the opening / closing shutter 104 is tilted in accordance with a signal from the control unit 190, thereby guiding the coins 10 to the handling unit 110. On the other hand, when coins 10 are not to be accepted, the opening / closing shutter 104 is lifted in accordance with a signal from the control unit 190, thereby discharging the coins 10 as they are, that is, dropping them onto the inclined surface 105.

[0023] As a result, even if a coin 10 is inserted into the coin insertion slot 102 in a state where it is not intended to accept coins 10, the coin 10 is smoothly discharged by the inclined surface 105 into the discharge tray 165. For example, even if the bucket 160 is lowered when the opening / closing shutter 104 is raised, the coin 10 inserted into the coin insertion slot 102 hits the inclined surface 105 and flows directly into the discharge tray 165, so that it is possible to prevent the coin 10 from falling down to the position of the bucket 160.

[0024] Referring to Figures 5 and 12, coins 10 sent to the overflow conveying path 1319 are configured to fall from the discharge outlet at the right front of the sorting section 120 along the right side surface of the housing 101 of the coin processing device 100 to the bottom end. <Configuration of Identification and Selection Unit 109>

[0025] Next, the configuration of the identifying and sorting unit 109 at the top of the coin processing device 100 will be described in detail. As described above, with reference to Figures 4, 5, and 13, the identifying and sorting unit 109 mainly includes a sorting unit 110 and a sorting unit 120. The sorting unit 110 is arranged on the front side, i.e., the front part, of the coin processing device 100, and is configured to send coins inserted one after another through the coin insertion slot 102 to the sorting unit 120 one by one. The sorting unit 120 is arranged on the back side, i.e., the rear part, of the coin processing device 100, and is configured to identify the type of coin sent from the sorting unit 110 and send it to a transport path according to its type. <Configuration of the separating unit 110>

[0026] First, the separating unit 110 will be described below. Referring to FIG. 5, the separating unit 110 is provided with a circular base 111 and a cylindrical side wall 112. An intake turntable 113 is disposed on the upper surface of the base 111. A plurality of holes 113X into which coins fit are formed in the intake turntable 113. In this embodiment, three holes 113X are formed. That is, the holes 113X are formed at 120° intervals around the drive shaft. The intake turntable 113 is driven by a motor, which will be described later, to push the coins that have fit into the holes 113X outward one by one from an outlet 112X at the rear of the side wall 112 and send them to the separating unit 120. 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 it hits the guide pin 114, it is pushed backward along the arrangement of the guide pins 114, i.e., to the outside of the side wall 112. <Configuration of the sorting unit 120>

[0027] Next, the sorting unit 120 will be described. With reference to FIGS. 5 and 13, the sorting unit 120 is provided with a circular base 121. A conveying rotor 123 driven by a motor (described later) is disposed above the base 121. A plurality of conveying pins 123X, 123X... are formed on the conveying rotor 123 to push coins forward from behind. 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 coins one by one along the periphery of the base 121 in a counterclockwise direction in a plan view. That is, in this embodiment, the sorting unit 120 can simultaneously convey and send out up to five coins to a conveying path.

[0028] The recognition unit 1330 uses a magnetic sensor or the like to determine whether coins sent by the conveying pins 123X are genuine or counterfeit, and to identify the type of coin. The recognition unit 1330 sends the determination result and the identification result to the microcomputer of the control unit 190. In this embodiment, the memory of the microcomputer stores the conveying path or the position of the storage case for each type of coin. Based on the determination result and the identification result, the control unit 190 drives the motor or solenoid on the base 121 to convey the coin to a reject path or to a conveying path or storage location according to the type of coin. As described above, the coin processing device 100 according to this embodiment conveys four types of coins toward the outside of the circular sorting unit 120 and four types of coins toward the bottom of the circular sorting unit 120, making it possible to sort and convey multiple types of coins in a compact manner. <Drive Mechanism of the Separating Unit 110 and the Sorting Unit 120>

[0029] Next, the drive mechanisms of the sorting unit 110 and the sorting unit 120 will be described. As shown in Fig. 13, the drive force of the drive motor 106 is transmitted to the intake rotation shaft 1131 of the intake turntable 113 of the sorting unit 110 via a plurality of gear groups 107, i.e., a gear reduction unit. In this embodiment, the drive force of the drive motor 106 is also provided to the conveying rotor 123 between the gear group 107 and the intake rotation shaft 1131. More specifically, the drive force of the drive motor 106 is also transmitted to the conveying rotation shaft 1231 of the conveying rotor 123 via a timing belt 1239 and a first pulley 1084 coaxial with the common shaft 1081 of a middle gear 1082 arranged at the rearmost end of the gear group 107.

[0030] That is, in this embodiment, as shown in FIG. 14, the driving force of one drive motor 106 is used to simultaneously drive the intake turntable 113 of the sorting section 110 and the conveying rotor 123 of the sorting section 120.

[0031] More specifically, a middle gear 1082 for receiving the driving force from the gear group 107 is fixed to the middle portion of the common shaft 1081. A first pulley 1084 is fixed to the upper portion of the common shaft 1081. The driving force transmitted to the first pulley 1084 is transmitted to a second pulley 1284 via a timing belt 1239, and then to the conveying rotation shaft 1231. Meanwhile, a time lag gear 1083 is loosely fitted to the lower portion of the common shaft 1081. The driving force of the middle gear 1082 is transmitted to the time lag gear 1083, and thereby the driving force is transmitted to the separation gear 1135 and the take-in rotation shaft 1131.

[0032] In particular, in this embodiment, the timing at which coins are sent out by the rotation of intake turntable 113 of handling unit 110 corresponds to the timing at which transport pins 123X of transport rotor 123 of sorting unit 120 start to send coins. As described above, intake turntable 113 of handling unit 110 has three holes 113X, 113X, 113X, and transport rotor 123 of sorting unit 120 has five transport pins 123X, 123X, 123X, 123X, 123X. Therefore, the number of teeth of the middle gear 1082 and time lag gear 1083 of the common shaft 1081, the diameter of the first pulley 1084, the number of teeth of the handling gear 1135 of the intake rotation shaft 1131, and the diameter of the second pulley 1284 of the conveying rotation shaft 1231 are set so that the conveying rotation body 123 of the sorting section 120 rotates 72° while the intake turntable 113 of the sorting section 110 rotates 120°.

[0033] As described above, in the coin processing device 100 according to this embodiment, coins inserted through the coin insertion slot 102 are sorted one by one by the sorting unit 110 and sent to the sorting unit 120. The three holes 113X, 113X, 113X of the take-in turntable 113 and the five transport pins 123X, 123X, 123X, 123X, 123X of the transport rotor 123 of the sorting unit 120 are configured to rotate in sync with each other to transfer coins. The coins sent to the sorting unit 120 are then judged by the recognition unit 1330 as to their authenticity, denomination, etc., and are then transported to the respective transport paths based on the results of the judgment. <Mechanism for clearing jams>

[0034] The following describes a mechanism for restoring the intake turntable 113 of the sorting unit 110 when it stops due to a coin jam or other reasons. In this embodiment, when the intake turntable 113 stops, as shown in Fig. 15, the driving of the conveying rotor 123 of the sorting unit 120 is stopped for a certain period of time, and only the intake rotation shaft 1131 is rotated in the reverse direction.

[0035] More specifically, in this embodiment, if coins become jammed at the outlet of the sorting section 110, the driving force of the drive motor 106 is transmitted to the middle gear 1082, the time lag gear 1083, and the intake rotating shaft 1131, but only the transmission of driving force to the conveying rotating body 123 is cut off.

[0036] 16, a second pulley 1284 around which a timing belt 1239 is wound is rotatably fitted with a gap to the conveying rotation shaft 1231. A ratchet gear 1235 that meshes with the lower surface of the second pulley 1284 is fixed to the conveying rotation shaft 1231. The ratchet gear 1235 is biased upward by a compression spring 1234 below. The ratchet gear 1235 is configured to transmit only the forward driving force from the second pulley 1284 to the conveying rotation shaft 1231 only when the teeth 1235X of the ratchet gear 1235 mesh with the teeth 1284X of the second pulley 1284.

[0037] 17, when the drive motor 106 rotates in the reverse direction, the driving force of the reverse rotation is transmitted to the common shaft 1081, the first pulley 1084, the timing belt 1239, and the second pulley 1284, but the teeth 1235X of the ratchet gear 1235 do not mesh with the teeth 1284X of the second pulley 1284, causing the ratchet gear 1235 to rotate freely, and the driving force is not transmitted to the conveying rotor 123. In other words, the conveying rotor 123 is stopped in the state where the reverse rotation has started. In this embodiment, the conveying rotor shaft 1232 is provided with a brake 1236 having a predetermined resistance.

[0038] Conversely, when the drive motor 106 starts to rotate in the forward direction, as shown in Figure 16, the forward rotation is transmitted to the conveying rotation shaft 1231, the conveying rotor 123, and the conveying pins 123X, 123X, and 123X via the common shaft 1081, the first pulley 1084, the timing belt 1239, the second pulley 1284, and the ratchet gear 1235.

[0039] 16 to 18, in this embodiment, the circumference of the ratchet ring is divided into five parts. That is, the number of divisions of the circumference is set to match the number of conveying pins 123X, 123X.... Therefore, regardless of the degree of reverse rotation of drive motor 106, when drive motor 106 resumes forward rotation, the timing at which conveying rotation shaft 1231 and conveying rotor 123 start forward rotation can be synchronized in relation to common shaft 1081 and the like.

[0040] 19, in the drive mechanism of the separating unit 110, a time lag gear 1083 is loosely fitted below a middle gear 1082 of a common shaft 1081. The forward rotational driving force or reverse rotational driving force of the middle gear 1082 is transmitted to the time lag gear 1083, causing the separating unit 110 to rotate forward or reverse.

[0041] 19 and 20, in this embodiment, two protrusions 1082X, 1082X are formed on the lower surface of the middle gear 1082. Two recesses 1083X, 1083X into which the two protrusions 1082X, 1082X are fitted are formed on the upper surface of the time lag gear 1083. The radial lengths of the two recesses 1083X, 1083X are longer than the radial lengths of the two protrusions 1082X, 1082X.

[0042] As a result, even if the drive motor 106 starts to rotate in the reverse direction, the separating unit 110 does not immediately start to rotate in the reverse direction, and even if the drive motor 106 starts to rotate in the forward direction again, the separating unit 110 does not immediately start to rotate in the forward direction. In this embodiment, the intake rotation shaft 1131 is also provided with a brake 1136 having a predetermined resistance.

[0043] In particular, in this embodiment, the radial angle corresponding to the recess 1083X of the time lag gear 1083 minus the radial angle corresponding to the protrusion 1082X of the middle gear 1082 is configured to be larger than the radial angle corresponding to one crest (tooth) of the ratchet gear 1235. As a result, when the drive motor 106 starts to resume forward rotation, the second pulley 1284 and the ratchet gear 1235 mesh first, the conveying rotor 123 starts to drive, and then the separating unit 110 starts to rotate forward. Therefore, two or more coins do not overlap with the conveying pin 123X of the conveying rotor 123, and the sorting process is smoothly resumed.

[0044] In other words, in this embodiment, the time that the sorting unit 110 and the sorting unit 120 are stopped or rotated in reverse is reduced, and the coin jam can be quickly removed and the sorting process can be resumed.

[0045] In this embodiment, a handling sensor 1133 is provided to detect the rotation of the import rotation shaft 1131, which is the drive shaft of the import turntable 113. This allows the microcomputer 191 according to this embodiment to detect, via the handling sensor 1133, whether the import turntable 113 is rotating forward, has stopped, or is rotating in the reverse direction.

[0046] In this embodiment, as shown in Fig. 20(A), the microcomputer 191 normally rotates the drive motor 106 in the forward direction, thereby rotating the separating unit 110 and the sorting unit 120 in the forward direction. At this time, the tips of the convex portions 1082X, 1082X of the middle gear 1082 are in contact with the tips of the concave portions 1083X, 1083X of the time lag gear 1083. The ratchet gear 1235 of the sorting unit 120 is also engaged with the concave portions 1083X, 1083X of the time lag gear 1083.

[0047] 20(B), when a coin becomes jammed in the separating unit 110, the separating unit 110 may stop. At this time, the drive motor 106 and the sorting unit 120 also stop. The microcomputer 191 may detect that the separating unit 110 has stopped based on a signal from the separating sensor 1133, the number of rotations of the drive motor 106, etc.

[0048] As shown in FIG. 20(C), the microcomputer 191 rotates the drive motor 106 in the reverse direction. At this time, the convex portions 1082X, 1082X of the middle gear 1082 start to slide inside the concave portions 1083X, 1083X of the time lag gear 1083. That is, the middle gear 1082 rotates freely in the reverse direction by 85°. Then, in the sorting unit 120, the second pulley 1284 starts to slide in the reverse direction on the upper surface of the ratchet gear 1235. That is, the second pulley 1284 also rotates freely.

[0049] 20(D), when the rear ends of the convex portions 1082X, 1082X of the central gear 1082 come into contact with the rear ends of the concave portions 1083X, 1083X of the time lag gear 1083, the time lag gear 1083 starts to rotate in the reverse direction. That is, the separating unit 110 rotates in the reverse direction, clearing the jammed coins. As for the sorting unit 120, the second pulley 1284 continues to slide on the upper surface of the ratchet gear 1235, so the sorting unit 120 remains stopped.

[0050] 20(E), after the microcomputer 191 has rotated the drive motor 106 in the reverse direction for a predetermined time, the microcomputer 191 stops the drive motor 106. Alternatively, after the microcomputer 191 has rotated the drive motor 106 in the reverse direction by a predetermined angle, for example, 360°, the microcomputer 191 stops the drive motor 106.

[0051] As shown in Figure 20 (F), the microcomputer 191 rotates the drive motor 106 in the forward direction. As a result, the convex portions 1082X, 1082X of the middle gear 1082 begin to slide within the concave portions 1083X, 1083X of the time lag gear 1083. In other words, the middle gear 1082 rotates freely in the forward direction by 85°. Then, in the sorting unit 120, the second pulley 1284 begins to slide in the forward direction on the upper surface of the ratchet gear 1235. In other words, the second pulley 1284 also rotates freely.

[0052] However, in this embodiment, the interval at which the ratchet gear 1235 rotates freely is shorter than the interval at which the time lag gear 1083 rotates freely, so the second pulley 1284 meshes with the ratchet gear 1235 first. In other words, the conveying rotor 123 and the conveying pins 123X, 123X... start to rotate forward first. In other words, the sorting unit 120 is configured to rotate before the sorting unit 110, by at least the interval of the conveying pin 123X.

[0053] Then, when the conveyance in the sorting unit 120 proceeds at least the distance equal to or greater than the distance between the conveying pins 123X, as shown in FIG. 20(G), the tips of the convex portions 1082X, 1082X of the middle gear 1082 come into contact with the tips of the concave portions 1083X, 1083X of the time lag gear 1083, and the time lag gear 1083 starts to rotate forward. In other words, the sorting unit 110 rotates forward. The sorting unit 120 continues to rotate forward. <Summary>

[0054] In the above embodiment, a coin processing device is provided that includes a handling unit that receives coins and sends them out one by one, a sorting unit that receives coins one by one from the handling unit and moves the coins along an arc while determining the type of coin or medal and guiding them to a path for each type, a common motor that provides driving force to the handling unit and the sorting unit, and a computer that reverses the motor when the rotation of the handling unit stops. While the handling unit is rotating in the reverse direction, the sorting unit is stopped.

[0055] Preferably, when the motor resumes forward rotation, the sorting unit and the separating unit resume forward rotation.

[0056] Preferably, a ratchet mechanism is provided on the drive shaft of the sorting unit, so that the sorting unit is stopped while the separating unit is rotating in the reverse direction, and the forward rotation of the sorting unit is resumed when the motor resumes forward rotation.

[0057] Preferably, the intervals at which the ratchet mechanism engages are configured to match the intervals at which coins are transported by the sorting section.

[0058] Preferably, a time lag mechanism is provided in the transmission path from the motor to the drive shaft of the sorting unit, so that when the motor resumes forward rotation, the sorting unit starts forward rotation first, and then the sorting unit starts forward rotation later.

[0059] Preferably, the time lag mechanism is configured such that when the motor resumes forward rotation, the sorting section rotates forward for a period longer than the conveying interval, and then the separating section starts to rotate forward.
