[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention are within the scope of protection of the present invention.

[0031] The commemorative coin self-service exchange device in this embodiment of the invention is mainly used for the self-service exchange of ordinary commemorative coins. Boxed commemorative coins can be directly placed into the device, and the box will be automatically opened and the coins will be dispensed in the form of rolls of commemorative coins. This realizes the self-service exchange of ordinary commemorative coins, reduces the labor intensity of staff, and improves the exchange efficiency.

[0032] It should be noted that, Figure 1 - Figure 3 As shown in the embodiment of the present invention, the boxed commemorative coins referred to are the ordinary commemorative coins with the largest issuance volume and the largest exchange volume. The boxed commemorative coin 5 is a cardboard box package containing several rolls of commemorative coins 52. The outer packaging box 51 of the boxed commemorative coins is sealed at both ends with glue. The rolls of commemorative coins 52 are made of paper or acrylic material and contain multiple commemorative coins. Generally, a roll of commemorative coins 52 contains twenty or forty commemorative coins. The commemorative coin self-service exchange device in this embodiment of the present invention ultimately exchanges for rolls of commemorative coins.

[0033] like Figure 4 - Figure 11 As shown, the commemorative coin self-service exchange device includes an outer shell 1, a boxed commemorative coin storage mechanism 2, a box-opening mechanism 3, and a coin dispensing mechanism 4. The boxed commemorative coin storage mechanism 2, the box-opening mechanism 3, and the coin dispensing mechanism 4 are all located in the outer shell 1. The boxed commemorative coin storage mechanism 2 includes a support frame 21, on which multiple packaging box storage slots are arranged vertically. Each packaging box storage slot can hold a boxed commemorative coin 5. The box-opening mechanism 3 is located on one side of the support frame 21. The function of the box-opening mechanism 3 is to grab the boxed commemorative coin 5 placed in the packaging box storage slot and open the outer packaging of the boxed commemorative coin 5, so that the rolled commemorative coin 52 slides out of the packaging box. After sliding out, the rolled commemorative coin 52 falls into the coin dispensing mechanism 4 and is output from the coin dispensing mechanism 4, thereby completing the automatic exchange of commemorative coins.

[0034] The above setup eliminates the need for bank branch staff to unpack the coins, thus reducing their workload. They only need to place the boxed commemorative coins into the storage compartment of the packaging box to achieve self-service exchange of rolled commemorative coins, which greatly reduces the problems of long waiting times and high workload for staff when exchanging at the counter.

[0035] In some embodiments, the support frame 21 is disposed in the housing 1, and the rear side of the housing 1 is provided with a corresponding feeding door 11. The support frame 21 is disposed in correspondence with the feeding door 11, so as to facilitate the placement of boxed commemorative coins from the feeding door 11. Multiple L-shaped plates 22 are arranged vertically at intervals on the support frame 21. At the same time, two rows of L-shaped plates 22 are arranged horizontally at intervals. Two L-shaped plates 22 arranged horizontally at intervals form a packaging box storage position. At the same time, two rows of packaging box storage positions are also provided to increase the storage capacity of boxed commemorative coins in the support frame 21 and avoid frequent filling of boxed commemorative coins.

[0036] like Figure 6 - Figure 9 As shown, the unpacking mechanism 3 includes an X-axis linear module 31, a Y-axis linear module 32, a Z-axis linear module 33, a boxed commemorative coin gripping mechanism 34, and an unpacking device 35. The X-axis linear module 31 is located at the bottom of the outer casing 1, the Y-axis linear module 32 is located on the X-axis linear module 31, the Z-axis linear module 33 is located on the Y-axis linear module 32, the boxed commemorative coin gripping mechanism 34 is located on the Z-axis linear module 33, and the unpacking device 35 is located on the boxed commemorative coin gripping mechanism 34. The X-axis linear module 31 can drive the boxed commemorative coin gripping mechanism 34 to move along the X-axis, facilitating the transfer of the boxed commemorative coins 5. The Y-axis linear module 32 can drive the boxed commemorative coin gripping mechanism 34 to move along the Y-axis, facilitating movement between the two rows of packaging box storage positions. The Z-axis linear module 33 can drive the boxed commemorative coin gripping mechanism 34 to move along the Z-axis, facilitating the lifting and gripping of the boxed commemorative coin 5 by the boxed commemorative coin gripping mechanism 34.

[0037] Specifically, the boxed commemorative coin gripping mechanism 34 includes a rotating module 341, a support plate 342, and a conveyor belt 343. The rotating module 341 is connected to the Z-axis linear module 33. The support plate 342 is mounted on the rotating module 341, and the conveyor belt 343 is mounted on the support plate 342. When actually gripping the boxed commemorative coins, the X-axis linear module 31 drives the conveyor belt 343 to insert below the boxed commemorative coin. Then, the Z-axis linear module 33 drives the conveyor belt 343 to rise to lift the boxed commemorative coin 5. Then, the X-axis linear module 31 drives the conveyor belt 343 to reset, thus gripping the boxed commemorative coin 5 onto the conveyor belt 343. After the boxed commemorative coin 5 is gripped onto the conveyor belt 343, it is moved from one end of the conveyor belt 343 to the other end by the conveyor belt 343, thereby opening the box.

[0038] like Figure 9As shown, the box-opening device 35 includes a clamping plate 351, a clamping device 352, and a box-cutting device 353. The clamping plate 351 is located at the end of the support plate 342 away from the support frame 21. The clamping plate 351 is located on both sides of the support plate 342 and extends upward. The clamping device 352 is located on the outside of the clamping plate 351. In this embodiment, the clamping device 352 is a cylinder or an electric push rod. The clamping device 352 can extend and retract to abut against the outer wall of the boxed commemorative coin, thereby fixing the boxed commemorative coin. After fixing, the box-cutting device 353 can be used to cut the seal of the outer packaging box 51, thereby opening the seal of the outer packaging box 51. The box-cutting device 353 includes a telescopic device and a cutter. The telescopic device is set up vertically, and the cutter is set on the telescopic device. At the same time, the cutter is located at the end of the boxed commemorative coins. The telescopic device drives the cutter to move upward, cutting the sealing cardboard at the end of the box, thereby opening the seal at the end of the boxed commemorative coins. After the seal is opened, the rotating module 341 drives the entire support plate 342 and the conveyor belt 343 to flip, so that the roll of commemorative coins in the outer packaging box 51 slides out of the outer packaging box 51 by gravity, thus completing the unpacking of the boxed commemorative coins. After the commemorative coins are poured out, the rotating module 341 resets, and then the empty box is sent back to the corresponding packaging box storage position through the cooperation of the conveyor belt 343, the X-axis linear module and the Z-axis linear module 33. The staff can then take out the empty box.

[0039] After the unpacking and unloading of the roll of commemorative coins 52, the coin dispensing mechanism 4 can output the exchanged coins. Specifically, the coin dispensing mechanism 4 includes a roll of commemorative coins storage device 41 and a coin dispensing device 42. The roll of commemorative coins storage device 41 is located below the unpacking mechanism 3, so that it can receive the roll of commemorative coins 52. The coin dispensing device 42 is located below the roll of commemorative coins storage device 41, so that it can output the exchanged roll of commemorative coins 52.

[0040] like Figure 10 and Figure 11 As shown, the coin dispensing device 42 includes a supporting beam 421, a lower coin cylinder 422, and a circulating dispensing mechanism 43. The supporting beam 421 is connected to the inner wall of the outer casing 1. The lower coin cylinder 422 is arranged vertically on the supporting beam 421. The upper end of the lower coin cylinder 422 is connected to the roll commemorative coin storage device 41. The circulating dispensing mechanism 43 is arranged on the supporting beam 421 and is spaced apart from the lower coin cylinder 422. The function of the lower coin cylinder 422 is to hold the roll commemorative coins 52 to be exchanged. The function of the circulating dispensing mechanism 43 is to control the roll commemorative coins 52 in the lower coin cylinder 422 to be discharged one by one in sequence, avoiding continuous discharge.

[0041] like Figure 10As shown, the circulating discharge mechanism 43 includes a mounting plate 431, a mounting block 432, an upper slide bar 433, a lower slide bar 434, a slide bar drive disk 435, and a drive motor 436. The mounting plate 431 is connected to the support beam 421. The mounting block 432 is mounted on the mounting plate 431. Two slide grooves are provided on the mounting block 432 in the horizontal direction, and the two slide grooves are spaced apart vertically. The upper slide bar 433 and the lower slide bar 434 are set in the corresponding slide grooves. Both the upper slide bar 433 and the lower slide bar 434 are provided with protrusions 437. The slide bar drive disk 435 is rotatably mounted on the mounting plate 431. Two drive notches 438 are symmetrically provided on the edge of the slide bar drive disk 435. The protrusions 437 are engaged in the drive notches 438. When the slide bar drive disk 435 rotates, it can drive the upper slide bar 433 and the lower slide bar 434 to move back and forth. That is, the upper slide bar 433 and the lower slide bar 434 move in opposite directions. The drive motor 436 is connected to the slide bar drive disk 435. The drive motor 436 can drive the slide bar drive disk 435 to rotate back and forth. A stop bar 4331 is provided on the upper slide bar 433, and a stop plate 4341 is provided on the lower slide bar 434. An insertion groove is provided on the outer wall of the lower coin cylinder 422 along the vertical direction. In actual use, when the rolled commemorative coin 52 falls, it is first stopped by the stop bar 4331. Then the slide bar drive disk 435 rotates, the rolled commemorative coin 52 falls, and is stopped by the stop plate 4341 again. Then the slide bar drive disk 435 rotates again, the rolled commemorative coin 52 is removed from the lower coin cylinder 422, and another rolled commemorative coin 52 is stopped by the stop plate 4341. The cycle repeats, realizing the sequential feeding of the rolled commemorative coins 52.

[0042] like Figure 4 As shown, a touch screen 12 and a coin outlet 13 are provided on the front side of the front shell. The touch screen 12 is located on the upper part of the front side of the shell 1, and the coin outlet 13 is located on the lower part of the front side of the shell 1. The coin outlet 13 is connected to the coin tube 422. The user operates the touch screen 12 to exchange the commemorative coins. The exchanged roll of commemorative coins falls into the coin outlet 13, completing the self-service exchange of commemorative coins.

[0043] The commemorative coin self-service exchange device of the present invention has a reasonable structure and simple operation. Staff only need to put the boxed commemorative coins into the outer shell without opening the box, thus realizing the self-service exchange of commemorative coins. After the exchange is completed, staff only need to take away the empty box, which greatly reduces the labor intensity of staff. It can meet the self-service exchange needs of ordinary commemorative coins issued in most cases and is conducive to the promotion of various exchange outlets.
