This invention relates to a coin processing device.

[Prior Art] As a conventional coin processing device of this type, one disclosed in, for example, Japanese Utility Model Application Publication No. 131580/1983 is known. In this device, a coin stopper is provided in the front stage of the electronic coin validator, and a timer counts a predetermined time from when the coins are guided to the electronic coin validator until the coins are sorted by the sorting device. The stopper is projected until the timer finishes counting a predetermined time to prevent the next coin from entering the electronic coin validator.

[Problem that the invention seeks to solve]

In the conventional system described above, a timer is used to set the time during which the stopper protrudes and prevents subsequent coins from being inserted. If the timer is long, the timer must be set accordingly, which causes the problem that the processing speed of the electronic coin validator becomes slower.

An object of the present invention is to provide a coin processing device that can improve the processing speed of an electronic coin validator even if the first path is long.

[Means for solving problems]

The coin processing device of the present invention includes a first sensor provided at the entrance of the first passage, and a sensor that detects coins sorted by the sorting device and outputs a signal indicating the type of coin corresponding to the passage. is provided in each of the plurality of paths after sorting, and each time the first sensor detects a coin and outputs a signal, the electronic coin validator determines the type of coin indicated by the determination result of the electronic coin validator. a storage device that sequentially stores the information, and a comparison circuit that sequentially compares the type of coin indicated by the signal each time the sensor in the plurality of passages outputs a signal with the stored value in the order stored in the storage device, The present invention is characterized in that the distribution result by the distribution device is checked based on the output of the comparison circuit.

[Effect]

In this invention, since the types of coins are stored in the order in which they were inserted, it is possible to determine whether the coins have been correctly sorted by sequentially comparing the stored contents with the outputs of the sensors in each passage after sorting. can be determined.

In this case, it is possible to make it possible to introduce the next coin into the electronic coin validator as soon as the first sensor outputs a signal, or to remove the stopper that restricts the introduction of the coin into the electronic coin validator. It can also be removed. If the stopper is excluded, processing such as collection or return may be performed in accordance with the inspection of the distribution results.

〔Effect of the invention〕

According to this invention, there is no need to wait for the next coin to be inspected until the coins are sorted, so even if the path to the sorting device is long, the processing speed of the electronic coin validator can be increased.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. In addition, in this embodiment, the electronic coin validator does not have a stopper in front of it, but instead checks the coins continuously, detects missorting, and returns the coins. Needless to say, a stopper may be provided at the front stage, or a feed roller may be provided to delay the introduction of the coin into the electronic coin validator.

FIG. 1 is a partial sectional view for explaining the outline of an electronic coin validator, a coin sorting device, and a coin pooling device. The electronic coin validator 1 determines the type of passing coin, and when a genuine coin is detected, outputs a signal corresponding to the genuine coin, for example, a genuine coin signal of 10 yen, 50 yen, or 100 yen, as a determination result. Below the electronic coin validator 1, there are first and second sorting devices extending from a passage 10 directly below the electronic coin validator 1 toward a passage 15 that returns coins that have passed through the electronic coin validator 1. It is provided. The first distribution device includes a shutter 2 and a solenoid (not shown) that drives the shutter 2.
20) in the figure, and the second distribution device consists of a shutter 5 and a solenoid (not shown) (25 in FIG. 2) that drives the shutter 5. Normally, the shutters 2 and 5 are retracted outside the aisle, and the shutters 2 and 5 are retracted outside the aisle.
is open. As will be described later, when a genuine coin signal of 10 yen or 100 yen is output from the electronic coin validator 1, the shutter 2 projects into the passage, and the falling coins are sorted into the first passage 11. Further, when a genuine coin signal of 50 yen is output from the electronic coin validator 1, the shutter 5 projects into the passage, and the falling coins are sorted into the second passage 14.

A first sensor 6 and a second sensor 9 are provided in the passages 11 and 14, respectively, for detecting coins immediately after entering the passages 11 and 14, respectively. The sensors 6 and 9 may be photoelectric switches, proximity switches, or micro switches. When the sensor 6 detects a coin, the shutter 2 is retracted from the passage and returns to its original state, as will be described later. Further, when the sensor 9 detects a coin, the shutter 5 is retracted from the passage and returns to its original state.

The passage 11 branches into a third passage 12 and a fourth passage 13 in the middle, and a third sorting device is provided at the branch point. The third sorting device consists of a magnet 3. Since the 10 yen coin is made of copper, it is decelerated by the magnet 3 and distributed to the passage 12. On the other hand, since the 100 yen coin is made of cupronickel, it enters the passage 13 without being decelerated by the magnet 3.

A third sensor 7 and a fourth sensor 8 for detecting coins immediately after entering the passages 12 and 13, respectively.
are provided in the passages 12 and 13, respectively. The sensors 7 and 8 may have the same structure as the sensors 6 and 9.

A coin pooling device 16 is provided below the passages 14, 12, 13. Once the pool device 16 is connected to the passageway 14, 12, 13, the 50
A block having a cylinder 19 for yen coins, a cylinder 17 for 10 yen coins, and a cylinder 18 for 100 yen coins, a bottom plate (not shown) provided below this block, and a drive device for the block or bottom plate. (not shown).
Once the bottom plate of the pool device 16 is
8, each having a hole that can communicate with the cylinder 19,
The bottoms of the cylinders 17, 18 are closed, but when driven by a drive device, the coins in the cylinders 19, 17, 18 are dropped downward through the holes to be collected. Also, once the block of the pool device 16 is driven in a direction perpendicular to the direction of movement of the bottom plate, all of the coins in the cylinders 19, 17, 18 fall into the path leading to the return port.

2 is a block diagram of the control circuit, FIG. 3 is a flowchart showing the operation of the computer 81 shown in FIG. 2, and FIG. 4 is a data showing the main data in the storage device 79 shown in FIG. It is a layout diagram. In the initial state before a coin enters the electronic coin validator 1, the flip-flops 54-58, 74, 76 and the storage device 70 are all in a reset state. Therefore, the OR circuit 60 that receives the set output signals from the flip-flops 54 and 55 does not output a signal, and the NOR circuit 61 that receives the set output signal from the flip-flop 56 and the output signal from the OR circuit 60 outputs a signal and outputs a signal from the NAND circuits 51 and 52. , 53 is supplied with the signal. Nando circuit 5
The other input terminals 1, 52, and 53 are supplied with a 100 yen specie signal, a 10 yen specie signal, and a 50 yen specie signal from the electronic coin validator 1, respectively.

When signals are simultaneously supplied to both input terminals of the NAND circuits 51, 52, 53, the NAND circuits 51, 5
The output states of 2 and 53 are inverted and input to the direct set input terminals of flip-flops 54, 55, and 56, respectively, flip-flops 54, 55, and 56 are set, NOR circuit 61 stops outputting a signal, and NAND circuits 51, 52, and 53 gives a signal.
Therefore, when one of flip-flops 54, 55, 56 is set, flip-flop 5
Those which are not set among 4, 55 and 56 are prohibited by NAND circuits 51, 52 and 53 and are not set.

The output signal of the OR circuit 60 is designed to drive the solenoid 20 via the driver 67, so when a genuine coin signal of 100 yen or 10 yen is output from the electronic coin validator 1, the NAND circuit 51 or 52 and the flip-flop 54 or 55, an OR circuit 60, and a driver 67, the solenoid 20 is driven, the shutter 2 projects into the passage, and the 100 yen coin or 10 yen coin enters the passage 11 and is detected by the sensor 6. The coin detection signal of sensor 6 is supplied to trigger input terminals T of flip-flops 54 and 55. When the flip-flops 54 and 55 receive a signal at the trigger input terminal T, they read the input state of the grounded D input terminal and enter the reset state. As a result, the solenoid 20 becomes inoperative, and the shutter 2 is retracted out of the passage.

The set-side output signal of the flip-flop 56 is designed to drive the solenoid 25 via the driver 68, so when a genuine coin signal of 50 yen is output from the electronic coin validator 1, the NAND circuit 53, the flip-flop 56, and the driver 68 via solenoid 25
is driven, the shutter 5 projects into the passage, and the 50 yen coin enters the passage 14 and is detected by the sensor 9. The coin detection signal of sensor 9 is supplied to trigger input terminal T of flip-flop 56. When the flip-flop 56 receives a signal at the trigger input terminal T, it reads the input state of the grounded D input terminal and enters the reset state. As a result, the solenoid 20 becomes inoperative, and the shutter 5 is retracted out of the passage.

Note that approximately 0.5 seconds after any of the flip-flops 54, 55, and 56 is set and the NOR circuit 61 stops outputting a signal, the timer 62 connected to the output terminal of the NOR circuit 61 times out.
Direct reset input terminals of flip-flops 54, 55, 56 via differentiation circuit 63 and OR circuit 64
RD is supplied with a signal to flip-flop 54,5.
5, 56. The time required for the time-up set in time 62 is slightly longer than the time required for genuine coins to be sorted into aisle 11 or aisle 14. Timer 62, differentiation circuit 6
The reset circuit consisting of 3 is useful in the event of an allocation error, which will be discussed later. For example, if a 50 yen coin accidentally enters the passageway 11, the sensor 9 will not output a signal, so the flip-flop 56 will be reset by the timer 62 and the differential circuit 63.

Next, the distribution between 100 yen coins and 10 yen coins will be explained. The set side output terminals of the flip-flops 54 and 55 are connected to a return delay circuit 6, respectively.
5 and 66 are connected. Recovery delay circuit 6
5 and 66 continue to output signals for approximately 1 microsecond even after flip-flops 54 and 55 are reset, and supply signals to the D1 and D2 input terminals of storage device 70, respectively.

The storage device 70 stores the values input to the D1 and D2 input terminals every time the signal from the sensor 6 is received at the SI terminal, outputs the earliest stored value to the Q1 and Q2 output terminals, and outputs the first stored value to the SO terminal. Each time a signal is received, the next stored value is output to the Q1 and Q2 output terminals, and when a signal is output to at least one of the Q1 and Q2 output terminals, a signal is output to the OR output terminal. For example, 64 times are memorized. Fairchild's 3341 with capacity
It is composed of the elements.

Now, following the 100 yen coin, the 10 yen coin is in aisle 11.
It is assumed that the When the electronic coin validator 1 determines that the 100 yen coin is a positive 100 yen coin, the flip-flop 54 is set and the return time delay circuit 65 supplies a signal to the D1 input terminal of the storage device 70. . Thereafter, when the sensor 6 detects a 100 yen coin, a signal is supplied to the SI terminal of the storage device 70. At this time, since no signal is supplied to the D2 input terminal of the storage device 70, the storage device 70 reads "10" and outputs "101". That is, the storage device 70 outputs a signal to the Q1 output terminal and the OR output terminal. The signal output from the Q1 output terminal of the storage device 70 is supplied to one input terminal of the AND circuit 71, and the output signal of the OR output terminal of the storage device 70 is supplied to the other input terminal of the AND circuit 71. AND circuit 71 issues a signal.

When a 100 yen coin is detected by the sensor 6, the flip-flop 54 is reset to approximately 1
After microseconds, the output signal of the return delay circuit 65 disappears. Therefore, when a 10 yen coin is detected by the sensor 6, the storage device 70 reads "01" from the D1 and D2 input terminals via the return delay circuits 65 and 66. After that, the 100 yen coin is sent to sensor 8.
When detected by the sensor 8, the output signal of the sensor 8 is
The signal is input to the trigger input terminal T of the flip-flop 74. At this time, since "0" is input to the D input terminal of the flip-flop 74 via the NOT circuit 73 which inverts the state of the output signal of the AND circuit 71, the flip-flop 74 receives the input signal at the trigger input terminal T. The reset state will be maintained even if the The output signal of the sensor 8 is also supplied to the SO input terminal of the storage device 70 via an OR circuit 78.
Therefore, the storage device 70 outputs "0011". As a result, the output signal of the AND circuit 71 disappears.

AND circuit 72 that inputs the output signal output from both the Q2 output terminal and the OR output terminal of the storage device 70 when the storage device 70 outputs "011".
gives an output signal. This output signal inputs "0" to the D input terminal of the flip-flop 76 via the NOT circuit 75. Thereafter, when the sensor 7 detects a 10 yen coin, the detection signal is input to the trigger input terminal T of the flip-flop 76 and is also sent to the SO of the storage device 70 via the OR circuit 78.
input to the terminal. As a result, the output of the storage device 70 becomes "000".

The above AND circuits 71, 72, NOT circuit 7
3 and 75, and flip-flops 74 and 76 constitute an example of a comparison circuit that compares the stored value of the storage device 70 and the type of coin indicated by the signal each time the sensor 7 or 8 outputs the signal. .

Note that the output signals of the sensors 7, 8, and 9 are input to the computer 81 and used to calculate the input amounts of 10 yen, 100 yen, and 50 yen, respectively.

Next, a case where a distribution error occurs will be explained. If a 50 yen coin or a fake coin accidentally enters the passage 11, the flip-flops 54 and 55 will not be set, so the AND circuit 5 inputs the reset output signals of the flip-flops 54 and 55.
9 supplies a signal to the D input terminal of flip-flop 50. A trigger input terminal T of the flip-flop 57 is supplied with the output signal of the sensor 6. Therefore, when the sensor 6 outputs a signal, the flip-flop 57 is set, and its set side output signal is inputted to the computer 81 via the OR circuit 69 as a distribution error signal.

If a counterfeit coin accidentally enters passageway 14, flip-flop 56 will not be set, so flip-flop 56 provides a reset side output signal to the D input terminal of flip-flop 58. At this time, the signal from the sensor 9 enters the trigger input terminal T of the flip-flop 58, so the flip-flop 58 is set and inputs the set-side output signal to the computer 81 via the OR circuit 69 as a distribution error signal.

If a 10 yen coin is mistakenly sorted into the aisle 13, the AND circuit 71 is not outputting a signal, so the sensor is 8 enters the trigger input terminal T of the flip-flop 74, the flip-flop 74 is set, and the set-side output signal of the flip-flop 74 is sent to the computer 81 via the OR circuit 69.
to go into.

If a 100 yen coin accidentally enters the passageway 12, the AND circuit 72 is not outputting a signal, and the sensor 7 The signal from the flip-flop 76 enters the trigger input terminal T of the flip-flop 76.
6 is set, and the set side output signal of flip-flop 76 enters computer 81 via OR circuit 69.

In step 101 of FIG. 3, the computer 81 checks whether the OR circuit 69 is outputting a signal. When the computer 81 detects that a signal indicating a distribution error is output from the OR circuit 69,
A low level signal ``0'' is applied to line 82 in FIG. At the same time, the flip-flops 54, 55,
56 to reset the flip-flops 54, 55, and 56 (step 102). Next, the stored value in the storage area 134 in the storage device 79 is cleared (step 10).
3) Wait for 1 second (step 104), send the drive signal for the block of the pool device 16 to the line 83 (step 105), set the output level of the line 82 to high state "1" (step 106), and then
Return to 1.

When the computer 81 detects that the OR circuit 69 is not outputting a signal in step 101,
It is checked whether the sensor 7 has output a coin detection signal (step 107). When it is detected in this test that the sensor 7 has output a signal, it is checked whether the stored value in the storage area 131 of the storage device 79 is "0" (step 108). In this test, the memory value of the storage area 131 is "0"
When it is detected that
34 (step 109), and
1 is stored as "1" (step 110), and the process advances to step 112.

When the computer 81 detects that the sensor 7 is not outputting a signal in step 107, it sets the stored value in the storage area 131 to "0" (step 11).
1) and proceed to step 112. On the other hand, step 1
If it is detected in step 08 that the stored value in the storage area 131 is "1", the process also proceeds to step 112.

In step 112, the computer 81 checks whether the sensor 8 is outputting a signal.
In this test, if it is detected that the sensor 8 is outputting a signal, the storage area 132 of the storage device 79
It is checked whether the stored value of is "0".
(Step 113). In this test, storage area 1
When it is detected that the stored value of 32 is "0",
The value stored in the storage area 134 is read out, "100" is added, and the value is stored in the storage area 134 (step 11).
4) Set the storage value in the storage area 132 to "1" (step 115), and proceed to step 117.

When the computer 81 detects that the sensor 8 is not outputting a signal in step 112, it sets the stored value in the storage area 132 to "0" (step 11).
6), proceed to step 117. On the other hand, step 1
If it is detected in step 13 that the stored value in the storage area 132 is "1", the process also proceeds to step 117.

In step 117, the computer 81 checks whether the sensor 9 is outputting a signal.
When it is detected that the sensor 9 is outputting a signal in this test, the storage area 133 of the storage device 79
A check is made to see if the stored value of is "0" (step 118). In this test, if it is detected that the value stored in the storage area 133 is "1", the process returns to step 101, and if it is detected to be "0", the value stored in the storage area 134 is read out, "50" is added, and the value is stored. The data is stored in the area 134 (step 119), the storage value in the storage area 133 is set to "1" (step 120), and the process returns to step 101. On the other hand, when the computer 81 detects in step 117 that the sensor 9 is not outputting a signal, it sets the stored value in the storage area 133 to "0" (step 121) and returns to step 101.

By repeating steps 101, 107 to 121 above, the input amount is stored in the storage area 134.

After the input amount has been calculated without making any sorting mistakes, the well-known automatic vending operation of goods is carried out.
When collecting coins, the computer 81 outputs a signal to the line 84 to temporarily drive the drive device of the bottom plate of the pool device 16. Since these operations are generally well known, a detailed explanation will be omitted.

In the above embodiment, all the coins in the pool device are temporarily returned in response to an error in sorting 10 yen coins and 100 yen coins in the magnet 3, but when a signal is output from the sensor 6, the flip-flop 54 Alternatively, the set-side output signal of 55 may be read into the computer 81 to calculate the amount of money received, and even if there is a sorting error in the magnet 3, the coins in the pool device may be collected without being returned.
