Description

Technical Field

[0001] The utility model relates to a coin receiving device, in particular to a coin receiving device capable of identifying the authenticity and currency value of a coin. Background Art

[0002] Today's highly developed social civilization and technology have not only accelerated the pace of people's lives, but also made people's quality of life more convenient and fast. For this reason, in many public places, in order to take into account the convenience and timeliness that people value, most of them are equipped with automated vending machines or automated checkout machines, which can greatly save the cost of hiring personnel.

[0003] Generally, automated vending machines, automated checkout machines, and game machines in amusement parks use coin receiving devices to allow users to insert coins for selection and operation, so as to achieve the purpose of unmanned operation and self-service checkout. The coin receivers inside these machines are all equipped with sensing modules to identify the value and authenticity of the coins. Since coins, whether they are national currency or self-made tokens in amusement parks, will have different sizes depending on the value, the accuracy of the coin receiver in identifying the value and authenticity of the coins will be related to the livelihood and profits of the business operators, as well as the consumer's own consumption rights.

[0004] At present, the industry mostly uses eddy current sensors as the sensing module of metal coins to identify the authenticity and currency value of the inserted coins. However, the conventional practice is usually to set the entire set of induction coils of the sensing module on one side of the path through which the coins pass. However, the change in the inductance value formed by this method is easily affected by the position of the coin insertion (for example, close to the induction coil or far away from the induction coil), resulting in misjudgment of the authenticity of the coin, so that consumers have to repeat the coin insertion operation back and forth, causing inconvenience in use. Therefore, how to improve the accuracy of coin identification by the sensing module is a goal that researchers in this field are eager to improve. Utility Model Content

[0081] Please refer to Figure 1 , Figure 1 1 is a block diagram of a coin receiving device 100 according to an embodiment of the present invention. The coin receiving device 100 may include a first coil module 110, a first detection module 120, a control module 130, and a power module 140. The power module 140 is electrically connected to the first coil module 110, the first detection module 120, and the control module 130 to provide power to these modules. When a coin 10 enters through the coin inlet of the coin receiving device 100, it will first pass through the first coil module 110 and then pass through the first detection module 120. When the coin 10 passes through the first coil module 110, the first coil module 110 can generate a first inductance value according to the material and size of the entered coin 10 and transmit the first inductance value to the control module 130. In addition, when the coin 10 passes through the first detection module 120 , the first detection module 120 may generate a first detection signal according to the time when the coin 10 arrives at and leaves the first detection module 120 and transmit the first detection signal to the control module 130 .

[0082] The control module 130 may include a database 131. The database 131 stores a plurality of inductance values ​​corresponding to the denominations of a plurality of different coins generated by the first coil module 110 and a plurality of detection signals generated by the first detection module 120. Therefore, the control module 130 may compare the first inductance value with the plurality of inductance values ​​in its database 131. If the first inductance value matches one of the stored inductance values, the coin 10 is determined to be a genuine coin according to the matching inductance value and the denomination of the coin 10 is recorded. The control module 130 may also compare the first detection signal with the plurality of detection signals in its database 131. If the first detection signal matches one of the stored detection signals, the size of the coin 10 is determined according to the matching detection signal, and further determines whether the denomination of the recorded coin 10 matches the determined size. If the determined size is met, the coin 10 is guided to a storage space for storage. If the first inductance value does not match one of the stored inductance values ​​or the denomination of the recorded coin 10 does not match the determined size, the coin 10 is determined to be an unauthentic coin and is guided to the coin outlet of the coin receiving device 100 .

[0083] In one embodiment, the control module 130 may further include a counter 132. The counter 132 is configured to accumulate the counted coin values ​​when the recorded coin values ​​meet the determined size.

[0084] Please refer to Figure 2 , Figure 21 is a block diagram of a coin receiving device 200 according to another embodiment of the present invention. In this embodiment, the coin receiving device 200 further includes a second coil module 210, a second detection module 220 and a display module 230. The power module 140 is also electrically connected to the second coil module 210, the second detection module 220 and the display module 230 to provide power to these modules. When the coin 10 enters through the coin inlet of the coin receiving device 200, it will first pass through the first coil module 110 and the second coil module 210 in succession, and then pass through the first detection module 120 and the second detection module 220 in succession. The second coil module 210 is similar in structure to the first coil module 110 (to be described in detail later), and the second detection module 220 is similar in structure to the first detection module 120 (to be described in detail later).

[0085] When the coin 10 passes through the first coil module 110 and the second coil module 210, the first coil module 110 and the second coil module 210 can respectively generate a first inductance value and a second inductance value to the control module 130 according to the material and size of the incoming coin 10. In addition, when the coin passes through the first detection module 120 and the second detection module 220, the first detection module 120 and the second detection module 220 can respectively generate a first detection signal and a second detection signal to the control module 130 according to the time when the coin 10 arrives at and leaves the first detection module 120 and the time when the coin 10 arrives at and leaves the second detection module 220.

[0086] Similarly, the control module 130 can compare the second inductance value with a plurality of inductance values ​​in its database 131. If the second inductance value matches one of the stored inductance values, the control module 130 further determines whether the inductance value is the same as the inductance value that the first inductance value matches. If they are the same, the coin 10 is determined to be a genuine coin based on the matching inductance value and the coin value of the coin 10 is recorded. If they are different, the coin 10 is determined to be a non-genuine coin and the coin is guided to the coin outlet of the coin receiving device 200.

[0087] Similarly, the control module 130 can also compare the second detection signal with the multiple detection signals in its database 131. If the second detection signal matches one of the stored detection signals, the control module 130 further determines whether the detection signal is the same as the detection signal that the first detection signal matches. If they are the same, the size of the coin 10 is determined according to the matching detection signal, and further determines whether the currency value of the recorded coin 10 matches the determined size. If they are different, the coin 10 is determined to be non-genuine and the coin is guided to the coin outlet of the coin receiving device 200. If the currency value of the recorded coin 10 matches the determined size, the coin 10 is guided to a storage space for storage, and the control module 130 controls the counter 132 to accumulate the counted currency value and controls the display module 230 to display the accumulated currency value. If the currency value of the recorded coin 10 does not match the determined size, the coin is determined to be non-genuine and the coin 10 is guided to the coin outlet of the coin receiving device 200.

[0088] In one embodiment, the coin receiving device 200 further includes an indicator light module 240 electrically connected to the power module 140. When all components in the coin receiving device 200 are operating normally, the indicator light module 240 will emit light to inform the consumer that the coin receiving device 200 can be used normally. When at least one component in the coin receiving device 200 (e.g., at least one of the power module 140, the first coil module 110, the second coil module 210, the first detection module 120, the second detection module 220, etc.) is abnormal, or when there is a foreign object on the movement path of the coin, the indicator light module 240 will not emit light to inform the consumer that the coin receiving device 200 is abnormal and can be temporarily used.

[0089] In some embodiments, the coin receiving device 100 and / or the coin receiving device 200 may also have a learning mode. In the learning mode, the control module 130 may generate multiple inductance values ​​corresponding to the currency values ​​of multiple different coins of another country using the first coil module 110 and / or the second coil module 210, and generate multiple detection signals corresponding to the currency values ​​of multiple different coins of the country using the first detection module 120 and / or the second detection module 220, according to multiple different coins of another country entering the coin inlet for the first time, and store these inductance values ​​and detection signals in the database 131 to be used for comparing and identifying the authenticity and currency value of the coins of the corresponding country that enter the coin inlet later. In this way, the coin receiving device 100 and / or the coin receiving device 200 can be applied to different countries through the learning mode.

[0090] To further understand the structure and operation of the coin receiving device of the present invention, please refer to Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 . Figure 3 It is a structural schematic diagram of a coin receiving device 300 according to an embodiment of the present utility model. Figure 4 is based on Figure 3 A schematic structural explosion diagram of the coin receiving device 300 is shown. Figure 5 is based on Figure 4 Schematic diagram of the structure in which the first wall 410 and the second wall 420 in the coin receiving device 300 are connected. Figure 6 is based on Figure 4 A schematic structural diagram of the second wall 420 and the corresponding baffle 380 in the coin receiving device 300. Figure 7 is based on Figure 4 A schematic structural diagram of a side of the first wall 410 facing the second wall 420 in the coin receiving device 300. Figure 8 is based on Figure 4 A schematic structural diagram of a side of the first wall 410 in the coin receiving device 300 facing away from the second wall 420.

[0091] The coin receiving device 300 includes a first wall 410, a second wall 420, a first shell 430, a second shell 440 and a panel 450. The module of the coin receiving device 100 and / or the coin receiving device 200 is disposed on the first wall 410 or the second wall 420. The first shell 430 can be coupled to one side of the first wall 410 and the second wall 420, and the second shell 440 can be coupled to the other side of the first wall 410 and the second wall 420, and the first shell 430 and the second shell 440 are coupled to each other to cover the first wall 410 and the second wall 420. The panel 450 is connected to the front end of the first shell 430 and the second shell 440, and has two openings corresponding to the coin inlet 310 and the coin outlet 320 of the coin receiving device 300 for coins to enter and leave. In one embodiment, the display module 230 and / or indicator light module 240 may be disposed on the panel 450 , but the present invention is not limited thereto.

[0092] like Figure 5 , Figure 6 and Figure 7 As shown, the second wall 420 is arranged opposite to the first wall 410, and forms a coin inlet 310, a coin outlet 320 and a channel 330 with the first wall 410. The channel 330 connects the coin inlet 310 and the coin outlet 320, and the coin inlet 310 and the coin outlet 320 are located on the same side. In the coin receiving device 300 of this embodiment, as shown in FIG. Figure 7As shown, two coil modules (e.g., a first coil module 340 and a second coil module 350) and two detection modules (e.g., a first detection module 360 ​​and a second detection module 370) are depicted, but only one set of coil modules and detection modules or more than three sets of coil modules and detection modules may be set according to needs, and the present invention is not limited thereto.

[0093] The first coil module 340 and the second coil module 350 are arranged on the first wall 410 and are located at the channel 330 adjacent to the coin inlet 310. The first coil module 340 includes a first base 341 and a first coil 342. The first base 341 has a first opening OP1 and the channel 330 passes through the first opening OP1. The first coil 342 is wound on the first base 341 and is configured to generate a first inductance value in response to a coin passing through the first opening OP1. Similarly, the second coil module 350 includes a second base 351 and a second coil 352. The second base 351 has a second opening OP2 and the channel 330 passes through the second opening OP2. The second coil 352 is wound on the second base 351 and is configured to generate a second inductance value in response to a coin passing through the second opening OP2.

[0094] Specifically, if Figure 7 As shown, the first base 341 has a first side, a second side, a third side and a fourth side connected to form a first opening OP1, wherein the first side is connected to the first wall 410. When the first wall 410 is engaged with the second wall 420, the third side of the first base 341 passes through the first through slot 421 (as shown in FIG. Figure 8 As shown). Therefore, the connected first side, second side, third side and fourth side make the first base 341 roughly in the shape of a "mouth" in the direction facing the channel 330. The first coil 342 is surrounded by the first side, the second side, the third side and the fourth side. In this way, when the coin passes through the first opening OP1, it is equivalent to directly passing through the center part of the first coil 342. Therefore, no matter what the relative position of the coin is when the coin is inserted, the coin will directly pass through the entire first coil 342 when passing through the first coil module 340, so the first inductance value generated by the first coil 342 will not be affected, so that the error of the generated first inductance value is extremely small, thereby reducing the possibility of misjudgment of the control module and improving the accuracy of coin recognition.

[0095] The structure of the second coil module 350 is similar to that of the first coil module 340 . The second wall 420 further has a second through slot 422 to accommodate the second coil module 350 when coupled with the first wall 410 . The details can be referred to above and will not be described again.

[0096] In this embodiment, the first detection module 360 ​​is disposed on the first wall 410 and is located downstream of the channel 330 and the first coil module 340 and the second coil module 350 (that is, the order of the movement path of the coin in the channel 330 is the first coil module 340, the second coil module 350, and the first detection module 360). The second detection module 370 is disposed on the first wall 410 and is located downstream of the channel 330 and the first detection module 360 ​​(that is, the order of the movement path of the coin in the channel 330 is the first detection module 360 ​​and the second detection module 370).

[0097] In one embodiment, the first detection module 360 ​​includes a first infrared transmitter 361 and a first infrared receiver 362 both disposed on the first wall 410. The coin receiving device 300 also includes a first prism 363 disposed on the second wall 420 (eg, Figure 5 and Figure 6 360) and corresponds to the positions of the first infrared transmitter 361 and the first infrared receiver 362 of the first detection module 360. The first infrared transmitter 361 is configured to transmit infrared rays to the first prism 363. The first infrared receiver 362 is located above or below the first infrared transmitter 361 (in this embodiment, the first infrared receiver 362 is located below the first infrared transmitter 361), and is configured to receive infrared rays reflected from the first prism 363. In one embodiment, the first detection module 360 ​​can perform corresponding calculations based on the entire time that the coin contacts the infrared rays (that is, the time from when the coin touches the infrared rays to when it leaves the infrared rays) to generate a first detection signal, and the control module can determine the size of the coin based on the first detection signal (e.g., the time of contacting the infrared rays).

[0098] In this embodiment, since the first infrared transmitter 361 and the first infrared receiver 362 are located on the same side and in an up-and-down relationship, the infrared scanning range can be increased, thereby avoiding the problem that the coins of some countries are too small to be scanned. In addition, the first infrared transmitter 361 and the first infrared receiver 362 are both arranged on the same side (i.e., the first wall 410), so the circuit components and the circuit board 470 (such as Figure 8 As shown in the figure, the first infrared transmitter 361 and the first infrared receiver 362 can be directly arranged on the side of the first wall 410 away from the second wall 420. Compared with the first infrared transmitter 361 and the first infrared receiver 362 being arranged on different sides, the wiring can be simplified, thereby reducing the complexity of circuit design and the difficulty of assembly.

[0099] Similarly, the second detection module 370 includes a second infrared transmitter 371 and a second infrared receiver 372 disposed on the first wall 410. The coin receiving device 300 also includes a second prism 373 disposed on the second wall 420 (eg, Figure 5 and Figure 6 As shown in the figure, and corresponding to the positions of the second infrared transmitter 371 and the second infrared receiver 372 of the second detection module 370, the specific operations and functions of which are similar to those of the first detection module 360, will not be described in detail here.

[0100] In one embodiment, if Figure 5 , Figure 6 and Figure 8 As shown, the coin receiving device 300 further includes a baffle 380 and a solenoid valve 390. The baffle 380 is located in the channel 330 and between the first detection module 360 ​​(or the second detection module 370) and the coin outlet 320. The baffle 380 has a first area 381 and a second area 382, ​​and the second area 382 is closer to the first wall 410 than the first area 381. The second wall 420 has a baffle opening OP3 for the baffle 380 to pass through, as shown in FIG. Figure 6 The first wall 410 has a baffle groove 411 to accommodate the second area 382 of the baffle 380. Figure 7 The baffle 380 has a third through slot 383 and a flange 384 located at one side of the third through slot 383 in the first area 381. The solenoid valve 390 is connected to the baffle 380 and is configured to be controlled by the control module to drive the baffle 380 to move closer to or away from the second wall 420.

[0101] In one embodiment, in response to the control module determining that the coin is a genuine coin (the determination method can refer to the above embodiment), the control module controls the solenoid valve 390 to drive the baffle 380 to move close to the first wall 410, so that the first area 381 of the baffle 380 is located on the movement path of the coin in the channel 330, and the second area 382 of the baffle 380 is located in the baffle groove 411 of the first wall 410. Since the flange 384 is located in the first area 381, it can prevent the coin from moving toward the coin outlet 320 through the channel 330, so that the coin enters the accommodating space below the baffle 380 through the third through slot 383, such as the storage bin 441 (such as Figure 3 shown).

[0102] In one embodiment, in response to the control module determining that the coin is not a genuine coin, the control module does not control the solenoid valve 390. At this time, the second area 382 of the baffle 380 is located on the movement path of the coin in the channel 330. Since no through groove is formed in the second area 382, ​​the coin can pass through the second area 382 of the baffle 380 via the channel 330 and move to the coin outlet 320 to exit from the coin outlet 320.

[0103] In one embodiment, the coin receiving device 300 may further include a third detection module 460, such as Figure 7The third detection module 460 is disposed on the first wall 410 and below the baffle 380, and is configured to generate a third detection signal in response to a coin passing through the third detection module 460. The control module determines whether the coin passes through the third slot 383 and enters the accommodation space below the baffle 380 according to the third detection signal.

[0104] In one embodiment, the third detection module 460 may include a third infrared transmitter 461 and a third infrared receiver 462 both disposed on the first wall 410. The coin receiving device 300 further includes a third prism 463 disposed on the second wall 420 (eg, Figure 5 and Figure 6 4) and corresponds to the positions of the third infrared transmitter 461 and the third infrared receiver 462 of the third detection module 460. Similarly, the third infrared transmitter 461 is configured to transmit infrared rays to the third prism 463. The third infrared receiver 462 is located on one side of the third infrared transmitter 461 and is configured to receive infrared rays reflected from the third prism 463. In this way, the first detection module 360 ​​can perform corresponding operations according to whether the coin contacts the infrared rays to generate the third detection signal, and the control module can determine whether the coin has entered the accommodation space according to the third detection signal (e.g., the time of contacting the infrared rays).

[0105] In one embodiment, if Figure 8 As shown, the coin receiving device 300 further includes a circuit board 470. The circuit board 470 is disposed on the side of the first wall 410 away from the second wall. The control module (not shown) can be disposed on the circuit board 470, and is respectively connected to the first coil module 340, the second coil module 350 (optional), the first detection module 360, the second detection module 370 (optional), the solenoid valve 390, the third detection module 460 (optional), etc. via a plurality of wirings. Since the above-mentioned circuit components are all disposed on the same side (i.e., the first wall 410), the wiring on the circuit board 470 can be relatively simplified, thereby reducing the complexity of the circuit.

[0106] In summary, the coin receiving device provided by the utility model, through the opening design of the base of the coil module, allows the coin to directly pass through the entire coil when passing through the coil module, thereby reducing the error of the inductance value generated by the coil. In this way, the possibility of misjudgment of the control module can be reduced and the accuracy of coin recognition can be improved. In addition, by arranging the coil module and the detection module on the same side, the wiring of the control module and these components can be simplified, thereby reducing the complexity of the circuit.
