Description

Technical Field

[0001] This utility model relates to the field of financial machinery technology, and in particular to a coin recycling machine. Background Technology

[0002] The coin recycling equipment provided by related technologies typically includes, from top to bottom, a coin feeding mechanism, a sorting and identification mechanism, a temporary storage mechanism, and a coin dispensing mechanism. The coin feeding mechanism includes a coin receiving hopper and a coin feeding channel. The coin feeding channel connects the coin receiving hopper and the entrance of the sorting and identification mechanism. Coins placed in the coin receiving hopper can enter the sorting and identification mechanism through the coin feeding channel. The sorting and identification mechanism is connected to the temporary storage mechanism through multiple sorting channels. The temporary storage mechanism includes multiple change dispensers arranged horizontally, each connected to a corresponding sorting channel. Coins identified by the sorting and identification mechanism can enter the corresponding change dispenser through the sorting channel. The coin dispensing mechanism includes a coin dispensing channel and a coin dispensing hopper. The coin dispensing channel is inclined, with its high end connected to the temporary storage mechanism and its low end connected to the coin dispensing channel. The coin dispensing channel receives coins from each change dispenser and allows them to enter the coin dispensing hopper under gravity. Users can then retrieve coins from the coin dispensing hopper.

[0003] However, when there are many different denominations of coins, the arrangement of the various mechanisms in the coin recycling machines provided by the relevant technologies makes them bulky and cannot meet the needs of space-constrained places such as supermarkets and convenience stores for miniaturized equipment. Utility Model Content

[0004] The purpose of this utility model is to provide a coin recycling machine to reduce its size and meet the need for miniaturization in spaces with limited space.

[0013] Driven by the circular conveyor chain, each of the receiving slots can pick up a coin as it passes the lower end and transport the coin from bottom to top to the identification and sorting mechanism.

[0014] As a preferred technical solution for the coin recycling machine, the depth of the coin receiving hopper extends vertically, and the width of the coin receiving hopper and the width of the annular conveyor chain both extend horizontally. The difference between the width of the coin receiving hopper and the width of the annular conveyor chain is less than the sum of the outer diameters of two coins, and the width of the annular conveyor chain is greater than or equal to the outer diameter of one coin and less than the sum of the outer diameters of two coins.

[0015] The high end and the low end are spaced apart along a second horizontal direction. The annular conveyor chain transports the coins in the coin receiving hopper from bottom to top along the second horizontal direction to the identification and sorting mechanism. The second horizontal direction is perpendicular to the first horizontal direction.

[0018] The coin recycling machine also includes multiple temporary storage slides, the inlets of which are connected to multiple temporary storage and sorting sections in a one-to-one correspondence, and the outlets of which are connected to multiple change dispensers in a one-to-one correspondence. Each temporary storage slide is used to allow the coins sorted by the corresponding temporary storage and sorting section to slide down to the corresponding change dispenser.

[0019] As a preferred technical solution for the coin recycling machine, the identification and sorting mechanism further includes a recycling sorting section and a coin return sorting section. Both the recycling sorting section and the coin return sorting section are located in the sorting channel. Along the coin conveying direction, both the coin return sorting section and the recycling sorting section are located downstream of the identification section, and both the coin return sorting section and the recycling sorting section are located upstream of the temporary storage sorting section.

[0020] The coin recycling machine further includes a recycling section, a recycling chute, and a coin return chute. The recycling section is located below the coin receiving hopper. The inlet of the recycling chute is connected to the recycling sorting section, and the outlet of the recycling chute is connected to the recycling section. The recycling chute is used to allow the coins sorted by the recycling sorting section to slide into the recycling section. The inlet of the coin return chute is connected to the coin return sorting section, and the outlet of the coin return chute is connected to the coin dispensing hopper. The coin return chute is used to allow the coins sorted by the coin return sorting section to slide into the coin dispensing hopper.

[0021] As a preferred technical solution for a coin recycling machine, the temporary storage and sorting unit includes a sorting cavity, a gate, and a drive assembly. The sorting cavity has an opening communicating with the sorting channel. The gate is movably connected to the frame. The drive assembly is driven to the gate, and the drive assembly can drive the gate to move so that the gate has an open position (opening the opening) and a closed position (closing the opening). When the gate is in the open position, the sorting cavity is communicating with the sorting channel, and coins in the sorting channel can enter the sorting cavity. When the gate is in the closed position, the sorting cavity is isolated from the sorting channel, and coins in the sorting channel can pass through the temporary storage and sorting unit.

[0022] As a preferred technical solution for a coin recycling machine, the coin-operated mechanism includes a tray and a coin-feeding channel. The tray is used to receive coins inserted by the user, and the tray is provided with a coin inlet that allows one coin to pass through.

[0047] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0048] Please refer to Figures 1 to 5 This embodiment provides a coin recycling machine, which includes a frame 1 and coin-operating mechanism 2, coin-feeding mechanism 3, coin-identifying and sorting mechanism 4, temporary storage mechanism, and coin-dispensing mechanism 6, all disposed on the frame 1. The coin-operating mechanism 2 is used to insert coins 100; the coin-feeding mechanism 3 includes a coin hopper 31 and a belt-type coin-feeding assembly 32, the coin hopper 31 being used to receive the coins 100 inserted by the coin-operating mechanism 2; the coin-identifying and sorting mechanism 4 is located above the coin-feeding mechanism 3, and the belt-type coin-feeding assembly 32 is used to transport the coins 100 in the coin hopper 31 from bottom to top to the coin-identifying and sorting mechanism 4; the temporary storage mechanism includes multiple change dispensers 5, the multiple change dispensers 5 being arranged vertically (e.g., ...). Figure 1The change dispenser 5 (as indicated by arrows a, b) is arranged in sequence to receive coins 100 output by the sorting and identification mechanism 4. The coin dispensing mechanism 6 includes a belt-type coin dispensing component 61 and a coin hopper 62 located above the belt-type coin dispensing component 61. The belt-type coin dispensing component 61 receives coins 100 output by any change dispenser 5 and conveys the received coins 100 from bottom to top to the coin hopper 62. The belt-type coin receiving component 32, the belt-type coin dispensing component 61, and the temporary storage mechanism are arranged along a first horizontal direction (e.g., ...). Figure 1 and Figure 3 The coins are arranged sequentially (in the direction indicated by the middle arrow cd). Specifically, when a user needs to deposit 100 coins, the user inserts 100 coins into the coin-operated mechanism 2. The 100 coins inserted into the coin-operated mechanism 2 pass through the coin receiving hopper 31, the belt-type coin-infeeding component 32, and the identification and sorting mechanism 4 in sequence, and then enter the corresponding change dispenser 5 according to their denominations. When a user needs to retrieve 100 coins, the change dispenser 5 outputs 100 coins to the belt-type coin-dispensing component 61, which transports 100 coins to the coin-dispensing hopper 62, where the user can then retrieve the 100 coins from the coin-dispensing hopper 62.

[0049] The coin recycling machine provided in this embodiment has the coin inlet mechanism 3, the belt-type coin outlet assembly 61, and the change dispenser 5 arranged sequentially along the first horizontal direction, which can effectively reduce the size of the coin recycling machine along the height direction. In addition, the multiple temporary storage mechanisms are arranged along the vertical direction, which can make full use of the vertical space to store coins 100. The belt-type coin inlet assembly 32 and the belt-type coin outlet assembly 61 both transport coins 100 from bottom to top, which can make full use of the vertical space to transport coins 100. Through the reasonable allocation and utilization of the vertical space, the size of the coin recycling machine along the horizontal direction can be effectively reduced. Therefore, the coin recycling machine provided in this embodiment has a compact structure, which can meet the requirements of miniaturization of the coin recycling machine while meeting the requirements of processing coins 100 of multiple denominations.

[0050] Alternatively, please refer to Figure 1 and Figure 4 The coin-operated mechanism 2 includes a tray 21 and a coin-feeding channel 22. The tray 21 receives coins 100 inserted by the user and has a coin inlet 211 that allows one coin 100 to pass through. The coin-feeding channel 22 connects the coin inlet 211 and the coin receiving hopper 31. Specifically, the coin inlet 211 is circular, and its inner diameter is larger than the outer diameter of one coin 100 but smaller than the sum of the outer diameters of two coins 100. This design allows the coins 100 inserted by the user into the tray 21 to fall one by one into the coin receiving hopper 31 through the coin inlet 211 and the coin-feeding channel 22, enabling the belt-type coin-feeding assembly 32 to promptly transport the coins 100 in the coin receiving hopper 31 to the sorting and identification mechanism 4.

[0051] Alternatively, please refer to Figure 2Along the vertical direction, the tray 21, the coin dispenser 62, and the coin receiving hopper 31 are arranged from top to bottom. The coin inlet channel 22 includes a first channel segment 221, a second channel segment 222, and a third channel segment 223 connected in sequence. The first channel segment 221 is located above the coin dispenser 62 and is connected to the coin inlet 211. The second channel segment 222 is arranged side by side with the coin dispenser 62 along the first horizontal direction. The third channel segment 223 is located below the coin dispenser 62 and is connected to the coin receiving hopper 31. This arrangement allows the coins 100 placed on the tray 21 by the user to fall sequentially into the coin receiving hopper 31 through the coin inlet 211, the first channel section 221, the second channel section 222, and the third channel section 223. Furthermore, the second channel end 222 and the coin outlet hopper 62 are arranged side by side along the first horizontal direction, which improves the compactness of the arrangement of the tray 21, the coin outlet hopper 6, the coin receiving hopper 31, and the coin inlet channel 22, thereby improving the compactness of the coin recycling machine and making it more conducive to the miniaturization design of the coin recycling machine.

[0052] Alternatively, please refer to Figure 3 and Figure 4 The belt-type coin dispensing assembly 61 includes an inlet section 611, a transport section 612, and an outlet section 613. The outlets 53 of multiple change dispensers 5 are arranged vertically in a row. The inlet section 611 is located below the outlet 53 of the lowest layer of change dispensers 5 and is used to receive the coin 100 dispensed by any change dispenser 5. The transport section 612 extends vertically and is used to transport the coin 100 from bottom to top to the outlet section 613. The outlet section 613 is located above the coin dispensing hopper 62 and is used to transport the coin 100 to the coin dispensing hopper 62. This arrangement ensures that the coin 100 dispensed by each change dispenser 5 falls to the inlet section 611 under its own gravity, is transported upwards by the transport section 612 to the outlet section 613, and then falls into the coin dispensing hopper 62, resulting in smooth and stable coin dispensing.

[0053] Alternatively, please continue to refer to Figure 3 and Figure 4The belt-type coin dispensing assembly 61 includes at least two annular belts, and the at least two annular belts cooperate to form an inlet section 611, a transport section 612, and an outlet section 613. This arrangement makes the spatial layout of the belt-type coin dispensing assembly 61 more flexible and reduces space occupation. Specifically, this embodiment exemplarily provides a scheme in which the belt-type coin dispensing assembly 61 includes two annular belts, including a first annular belt 614 and a second annular belt 615. The first annular belt 614 is supported by multiple first rollers, and the second annular belt 615 is supported by multiple second rollers. The first annular belt 614 and the second annular belt 615 cooperate to form the inlet section 611, the transport section 612, and the outlet section 613. The coin dispensing mechanism 6 also includes a coin dispensing motor 63, which is simultaneously connected to the first annular belt 614 and the second annular belt 615 for driving the first annular belt 614 and the second annular belt 615 to move synchronously. In other embodiments, the belt-type coin dispensing assembly 61 may also include one, three, or more annular belts according to actual needs. Preferably, please refer to Figure 4 Along the second horizontal direction (e.g.) Figure 1 and Figure 4 (As indicated by the arrow ef), the coin inlet channel 22 and the belt-type coin outlet component 61 are arranged side by side. This arrangement further improves the structural compactness of the coin recycling machine. The second horizontal direction is perpendicular to the first horizontal direction.

[0054] Alternatively, please refer to Figures 3 to 5 The belt-type coin feeding assembly 32 includes an annular conveyor chain 321, which is inclined and has a lower end 322 and a higher end 323 spaced apart in the vertical direction. The lower end 322 is located in the coin receiving hopper 31 and is used to support the coin 100. The higher end 323 is connected to the identification and sorting mechanism 4. The surface of the annular conveyor chain 321 is provided with a plurality of receiving slots 324, which are arranged sequentially along the moving direction of the annular conveyor chain 321. Driven by the annular conveyor chain 321, each receiving slot 324 can pick up a coin 100 when passing the lower end 322 and transport the coin 100 from bottom to top to the identification and sorting mechanism 4. With this configuration, when the circular conveyor chain 321 moves, it causes the coins 100 supported on the lower end 322 of the circular conveyor chain 321 to vibrate and randomly fall into the receiving groove 324 passing through the lower end 322 and be picked up by the receiving groove 324. The coins 100 that fall into the receiving groove 324 are transported to the identification and sorting mechanism 4 above as the circular conveyor chain 321 moves. The size of the receiving groove 324 can only hold one coin 100, so that the circular conveyor chain 321 can transport the coins in the coin receiving hopper 31 one by one to the identification and sorting mechanism 4, so that the identification and sorting mechanism 4 can identify and sort the coins 100 one by one, thereby improving the accuracy of the identification and sorting mechanism 4 in identifying and sorting the coins 100.

[0055] Alternatively, please refer to Figure 5 In this embodiment, the belt-type coin inserter 32 is located inside the coin receiving hopper 31, and its high end 323 does not extend beyond the top of the coin receiving hopper 31, so that the belt-type coin inserter 32 does not occupy the space outside the coin receiving hopper 31. In other embodiments, the high end 323 of the belt-type coin inserter 32 can also be located outside the coin receiving hopper 31 as needed.

[0056] Alternatively, please refer to Figure 4 and Figure 5 The belt-type coin insertion assembly 32 also includes a first motor 325 and two spaced-apart sprockets 326. Both sprockets 326 are rotatably mounted on the frame 1. An annular conveyor chain 321 is fitted onto and supported by the two sprockets 326. The first motor 325 is connected to one of the sprockets 326 for driving the sprocket 326 to rotate around its own axis. When the sprocket 326 rotates, it drives the annular conveyor chain 321 to move. Specifically, in this embodiment, the lower end 322 and the upper end 323 of the belt-type coin insertion assembly 32 correspond to the positions of the two sprockets 326, respectively. The two sprockets 326 are spaced apart vertically and horizontally, thus causing the annular conveyor chain 321 to be inclined.

[0057] Alternatively, please refer to Figures 3 to 5 The depth of the coin receiving hopper 31 extends vertically, and the width of the coin receiving hopper 31 and the width of the annular conveyor chain 321 both extend horizontally. The difference between the width of the coin receiving hopper 31 and the width of the annular conveyor chain 321 is less than the sum of the outer diameters of two coins 100. The width of the annular conveyor chain 321 is greater than or equal to the outer diameter of one coin 100 and less than the sum of the outer diameters of two coins 100. The high end 323 and the low end 322 are spaced apart along the second horizontal direction. The annular conveyor chain 321 transports the coins 100 in the coin receiving hopper 31 along the second horizontal direction from bottom to top to the identification and sorting mechanism 4. This configuration, by ensuring that the width of the coin hopper 31 and the width of the annular conveyor chain 321 both extend along the first horizontal direction, and that the difference between the width of the coin hopper 31 and the width of the annular conveyor chain 321 is less than the sum of the outer diameters of two coins 100, and the width of the annular conveyor chain 321 is less than the sum of the outer diameters of two coins 100, reduces the size of the coin recycling machine along the first horizontal direction. Simultaneously, since the depth of the coin hopper 31 extends vertically, and the annular conveyor chain 321 transports the coins 100 from bottom to top along the second horizontal direction, the coin hopper 31 can accommodate the coins 100 using the vertical dimension of the temporary storage mechanism, and the annular conveyor chain 321 can be arranged using the dimension of the temporary storage mechanism along the second horizontal direction. This further improves the structural compactness of the coin recycling machine and facilitates its miniaturization.

[0058] Alternatively, please refer to Figure 3 and Figure 5 The coin receiving hopper 31 includes a bottom wall 311, a guide surface 312, and two side walls 313. The two side walls 313 are arranged opposite each other and spaced apart along a first horizontal direction. The bottom wall 311 is connected between the two side walls 313. An annular conveyor chain 321 is embedded in the bottom wall 311. The guide surface 312 is inclined and connects the bottom wall 311 and one of the two side walls 313. The guide surface 312 is used to guide the coin 100 to slide down onto the annular conveyor chain 321. This arrangement ensures that when the coin 100 falls along the side wall 313 into the coin receiving hopper 31, the guide surface 312 guides the coin 100 to slide down onto the annular conveyor chain 321, improving the reliability of the annular conveyor chain 321 in conveying the coin 100. Specifically, in this embodiment, the two sidewalls 313 are respectively the first sidewall and the second sidewall. The guide surface 312 is obliquely connected between the first sidewall and the bottom wall 311. The annular conveyor chain 321 includes a first edge and a second edge along its width direction. Along the first horizontal direction, the first sidewall, the first edge, the second edge, and the second sidewall are arranged sequentially. The distance between the first edge and the lower edge of the guide surface 312 is less than the outer diameter of a coin 100, and the distance between the second edge and the second sidewall is less than the outer diameter of a coin 100. This arrangement allows at least a portion of the coin 100 falling into the coin receiving hopper 31 to be supported by the annular conveyor chain 321. Furthermore, with the vibration and movement of the annular conveyor chain 321, the annular conveyor chain 321 can drive the coin 100 into the receiving slot 324, further improving the reliability of coin 100 conveying. In other embodiments, the coin receiving hopper 31 may also include two guide surfaces 312, which are respectively connected between two side walls 313 and bottom wall 311. The annular conveyor chain 321 includes two edges along its width direction, and the distance between each edge and the lower edge of its adjacent guide surface 312 is less than the outer diameter of a coin 100.

[0059] Alternatively, please refer to Figure 4 and Figure 5The identification and sorting mechanism 4 includes a sorting channel 41, an identification unit 42, and multiple temporary storage sorting units 43. One end of the sorting channel 41 is connected to the high end 323. The sorting channel 41 is used to receive and transport coins 100 output by the circular conveyor chain 321. The identification unit 42 is used to identify the coins 100. The identification unit 42 and multiple temporary storage sorting units 43 are both located in the sorting channel 41 and along the transport direction of the coins 100. The multiple temporary storage sorting units 43 are spaced apart and are all located downstream of the identification unit 42. Each temporary storage sorting unit 43 is located above the temporary storage mechanism. The coin recycling machine also includes multiple temporary storage slides 71. The entrances of the multiple temporary storage slides 71 are connected to the multiple temporary storage sorting units 43 one by one. The exits 53 of the multiple temporary storage slides 71 are connected to the multiple change dispensers 5 one by one. Each temporary storage slide 71 is used to allow the coins 100 sorted by the corresponding temporary storage sorting unit 43 to slide down to the corresponding change dispenser 5. This configuration ensures that when the coin 100 is conveyed to the identification unit 42 via the sorting channel 41, the identification unit 42 identifies the denomination of the coin 100 and, based on the denomination, conveys the coin 100 through the sorting channel 41 to the corresponding temporary storage sorting unit 43, and then slides down the corresponding temporary storage chute 71 to the corresponding change dispenser 5. Optionally, one end of the sorting channel 41 extends into the coin receiving hopper 31 and connects with the high end 323 of the circular conveyor chain 321. This configuration ensures that coins 100 accidentally dropped from the circular conveyor chain 321 can reliably fall into the coin receiving hopper 31 and be conveyed again by the circular conveyor chain 321 to the sorting channel 41, improving the reliability of coin conveying.

[0060] Alternatively, please refer to Figure 3 The change dispenser 5 includes a temporary coin storage hopper 51 and a second motor (not shown in the attached drawings). The bottom of the temporary coin storage hopper 51 has a turntable 52 and an outlet 53 communicating with the turntable 52. The turntable 52 supports the coins 100. The second motor is connected to the turntable 52 and drives the turntable 52 to rotate. When the turntable 52 rotates, it drives the coins 100 to be output through the outlet 53 to the belt-type coin dispensing assembly 61. Preferably, the rotation axes of the turntables 52 of the multiple change dispensers 5 coincide and all extend vertically, improving the compactness of the arrangement of the multiple turntables 52 and facilitating the miniaturization design of the coin recycling machine.

[0061] Alternatively, please refer to Figure 2The identification and sorting mechanism 4 also includes a recycling sorting section 44 and a coin return sorting section 45. Both the recycling sorting section 44 and the coin return sorting section 45 are located in the sorting channel 41, along the conveying direction of the coins 100. Both the coin return sorting section 45 and the recycling sorting section 44 are downstream of the identification section 42, and both are upstream of the temporary storage sorting section 43. The coin recycling machine also includes a recycling section 8, a recycling chute 72, and a coin return chute 73. The recycling section 8 is located... Below the coin receiving hopper 31, the inlet of the recycling chute 72 is connected to the recycling sorting section 44, and the outlet 53 of the recycling chute 72 is connected to the recycling section 8. The recycling chute 72 is used to allow the coins 100 sorted by the recycling sorting section 44 to slide down to the recycling section 8. The inlet of the coin return chute 73 is connected to the coin return sorting section 45, and the outlet 53 of the coin return chute 73 is connected to the coin dispensing hopper 62. The coin return chute 73 is used to allow the coins 100 sorted by the coin return sorting section 45 to slide down to the coin dispensing hopper 62. With this configuration, since both the coin return sorting section 45 and the recycling sorting section 44 are located upstream of the temporary storage sorting section 43, counterfeit coins identified by the identification section 42 can be promptly transported to the coin dispenser 62 via the coin return sorting section 45 and the coin return chute 73, and retrieved by the user. Coins 100 identified by the identification section 42 as unsuitable for circulation can be promptly transported to the recycling section 8 via the recycling sorting section 44 and the recycling chute 72 for recycling, preventing unsuitable coins 100 or counterfeit coins from being transported to the temporary storage sorting section 43 and entering the change dispensing section via the temporary storage chute 71. Furthermore, the recycling section 8 is located below the coin receiving hopper 31, further improving the compactness of the coin recycling machine. In other embodiments, the recycling section 8 can also be located above or to the side of the coin receiving hopper 31 as needed. In this embodiment, the recycling section 8 is a recycling box fixedly located below the temporary storage mechanism. Preferably, multiple temporary storage sorting sections 43, recycling sorting sections 44, and coin return sorting sections 45 are arranged sequentially along a first horizontal direction.

[0062] Alternatively, please refer to Figure 6 and Figure 7The temporary storage and sorting unit 43 includes a sorting cavity 431, a gate 432, and a drive assembly 434. The sorting cavity 431 has an opening that communicates with the sorting channel 41. The gate 432 is movably connected to the frame 1. The drive assembly 434 is driven to the gate 432 and can drive the gate 432 to move so that the gate 432 has an open position with the opening open and a closed position with the opening closed. When the gate 432 is in the open position, the sorting cavity 431 communicates with the sorting channel 41, and the coins 100 in the sorting channel 41 can enter the sorting cavity 431. When the gate 432 is in the closed position, the sorting cavity 431 is isolated from the sorting channel 41, and the coins 100 in the sorting channel 41 can pass through the temporary storage and sorting unit 43. For a specific denomination of coin 100, a temporary storage and sorting unit 43 corresponding to the denomination of coin 100 is defined as the target temporary storage and sorting unit, and each temporary storage and sorting unit 43 located upstream of the target temporary storage and sorting unit is defined as a non-target temporary storage and sorting unit. When the coin 100 needs to be transported to the target temporary storage and sorting unit through the sorting channel 41, the gates 432 of each non-target temporary storage and sorting unit are closed, and the gates 432 of the target temporary storage and sorting unit are open. Under the transport of the sorting channel 41, the coin 100 can pass through each non-target temporary storage and sorting unit in sequence to the opening of the target temporary storage and sorting unit, and can enter the sorting cavity 431 through the opening, thus improving the reliability of coin 100 sorting. Preferably, the gates 432 are rotatably connected to the frame 1 via a rotating shaft 437. More preferably, the drive assembly 434 includes an electromagnet 435 and a transmission member 436. The electromagnet 435 is connected to the gate 432 via the transmission member 436, and is used to drive the gate 432 to rotate relative to the frame 1 about the axis of the rotating shaft 437. In other embodiments, the gate 432 may also be slidably connected to the frame 1.

[0063] Alternatively, please refer to Figure 3 The sorting and identification mechanism 4 also includes a conveyor belt 47 and a third motor 46. When the gate 432 closes the opening, the gate 432 is opposite to the conveyor belt 47, forming a sorting channel 41 between the gate 432 and the conveyor belt 47 to hold and move the coins 100. The third motor 46 is connected to the conveyor belt 47 and drives the conveyor belt 47 to move the coins 100 along the sorting channel 41. This arrangement allows the coins 100 moving in the sorting channel 41 to be tightly pressed against the gate 432 by the pressure of the conveyor belt 47. Thus, when the gate 432 opens, the coins 100 can fall into the sorting chamber 431 under the pressure of the conveyor belt 47, further improving the sorting reliability of the temporary storage and sorting section 43.
