Description

[Detailed description of the invention] (Technical field of the invention) This invention detects the storage state of coins in a coin processing machine that counts coins of multiple denominations for each denomination and stores them in a storage section to prevent the coins from becoming full. Regarding equipment.

(Technical background of the invention and its problems) Conventionally, coin sorting and counting machines and circulating coin depositing and dispensing machines classify and store coins by denomination. These devices are designed to detect the full state of coin storage cylinders when stacking coins in the coin storage cylinders provided for each denomination. Either install a sensor etc. to detect coins that are stored almost full, or
Alternatively, when sorting coins, the number of coins is counted for each denomination to manage the number of stored coins and to detect a full state.

However, in the former detection method, if an optical sensor or the like is installed at the top of the coin storage cylinder, even if it is detected that the coin storage cylinder is full, some coins of the same denomination may be placed on the coin sorting path. is being transported,
There was a drawback that coins would overflow from the inside of the coin storage cylinder. Furthermore, even if the position of the optical sensor or the like in the coin storage cylinder is slightly lowered in order to improve this drawback, there is still the problem that the full state is detected even when the coins are not sufficiently stored. Furthermore, with the latter detection method, if the coins are not stacked properly in the coin storage cylinder and become three-dimensional, the number of coins will exceed the number by the time the full number of coins is counted. , reliably detects the number of stored coins,
Moreover, it could not be stored effectively enough.

(Purpose of the invention) This invention was made due to the above-mentioned circumstances, and the purpose of this invention is to reliably detect the number of coins of multiple denominations stored in coin storage cylinders provided for each denomination. Another object of the present invention is to provide a coin storage state detecting device for a coin processing machine that is capable of effectively storing coins until the inside of the cylinder is full of coins.

(Summary of the invention) This invention relates to a coin storage state detection device in a coin processing machine, and includes a sorting passage section that conveys coins of multiple denominations one by one and sorts them into denominations, and a coin storage state detection device for a coin processing machine. a discriminating means provided upstream of the sorting passage section for discriminating types, etc.; a first counting memory for counting and storing the number of coins discriminated by the discriminating means for each denomination; A passing sensor means provided in the sorting passage section for detecting each coin; a second counting memory for counting and storing the number of coins detected by the passing sensor means for each denomination; a storage section for storing coins detected by the passage sensor means according to denomination; a storage sensor means provided in the storage section for each denomination for detecting the stored coins; A third counting memory that counts predetermined pulse signals for each denomination while detecting coins stored in the storage section; and a management memory for storing the contents of the second counting memory, and when the numerical difference stored in the first counting memory and the management memory reaches a predetermined value, the denomination storage section is in a full state. It is designed to be judged.

(Embodiment of the invention) Fig. 1 shows the block configuration of a coin storage state detection device in a coin processing machine which is an embodiment of the invention. Here, 1 yen, 5 yen, 50 yen, 100 yen
6 denominations of yen, 10 yen, and 500 yen) are transported one by one.
It has a classification passage section 1 for classifying by denomination. The sorting passage section 1 is provided with discharge ports 10 to 15 from upstream to downstream for discharging classified coins of multiple denominations according to the respective diameters of the coins.
Coin storage tubes 16 to 21 are provided below coins 0 to 15, respectively, for storing ejected coins of each denomination. Note that the coin storage tubes 16 to 21 may be configured such that the coins stored therein are released from the bottom as necessary. Further, on the upstream side of the discharge port 10 of the sorting passage section 1, an identification sensor 2 consisting of a magnetic or optical sensor element or the like is provided, which detects the denomination of the coin being conveyed and outputs a detection signal K1.
The detection signal K1 is input to the denomination discrimination unit 3 which determines the denomination of the coin and outputs signals SC1 to SC6 indicating the number of coins of each denomination, and the signals SC1 to SC6 are input to the first counting memories 31 to 36, respectively. (Count values SC01 to SC06) The count values SC01 to SC06 of the first counting memories 31 to 36 are input to determination circuits 91 to 96, respectively. Between the discharge ports 10 to 15 and the coin storage tubes 16 to 21, there are optical sensor elements, etc. that detect coins that have fallen into and been stored in the coin storage tubes 16 to 21 and output signals ST1 to ST6. Passage sensors 41 to 46 are provided,
The signals ST1 to ST6 are respectively output from the second counting memory 51 to
56 and the number of coins is counted (count value
STC1~STC6). In addition, each coin storage section 16 to 21
Near full sensors 61 to 66, which are comprised of optical sensor elements, etc., are provided on the top of the holder to detect a stored coin and output signals TC1 to TC6 with a pulse width corresponding to the light shielding by the coin. TC1
~TC6 are input to the third counting memories 71 to 76, respectively, and the clock pulse signal CLK of a predetermined frequency is counted according to the pulse width (count value TC01
~TC06). In addition, these third counting memories 71 to 7
When pulse signals TC1 to TC6 are not applied to 6, that is, when the coin is not shielded from light by near full sensors 61 to 66, the third counting memories 71 to 76
These are each subtracted by the clock pulse signal CLK having the predetermined frequency. Each coin storage section 16 is placed in the third counting memory 71 to 76.
~21 limit values α1 to α6 are predetermined according to the storage amount and the thickness of each denomination coin, and the count values TC01 to TC06 become the set limit values α1 to α6. When the latch signal LT1
~It is now outputting LT6. latch signal
LT1 to LT6 are input to management memories 81 to 86,
Management memory 8 to which latch signals LT1 to LT6 are input
1 to 86, the Nyalf management flags NFK1 to NFK6 are turned on, and the count values STC1 to STC6 at that time are read from the second count memories 51 to 56, and the count values RC01 to RC01 are read.
Save as RC06. The count values RC01 to RC06 stored in the management memories 81 to 86 are input to determination circuits 91 to 96, respectively, and the first count memories 31 to
When the difference between the count values SC01 to SC06 of 36 exceeds preset values x1 to x6, it is assumed that each coin storage cylinder 16 to 21 is full, and the near full flags NFA1 to NFA6 are output. It's getting old.

FIG. 2 shows the correspondence between the coins of each denomination (1 yen to 500 yen) detected by this coin storage state detection device and the contents of each memory and determination circuit. Here, 1 yen, 5 yen, 50 yen, 100 yen, 10 yen,
The figure shows a 500 yen coin, and the management memory 8
1 to 86 are storage areas corresponding to each coin (RC01
-RC06) and near-full management flags NFK1 to NFK6 that are turned on by latch signals LT1 to LT6. Further, the determination circuits 91 to 96
are the near-full flags NFA1 to NFA6 that are turned on when the above-mentioned differences exceed set values x1 to x6, which are predetermined according to the respective distances from the identification sensor 2 to the coin storage tubes 16 to 21, respectively. It has an area.

In such a configuration, its operation will be explained with reference to the timing chart of FIG. 3 and the flow chart of FIG. 4. Here, we will explain using a 1 yen coin as an example, but 5 yen, 50 yen, 100 yen,
The same applies to 10 yen and 500 yen coins.

First, when coins (1 yen) are conveyed one by one from upstream of the sorting passage section 1 (for example, from a stocker), they are detected by the identification sensor 2 and the detection signal is
K1 is output and inputted to the denomination discrimination section 3, where the denomination is discriminated and the first counting memory 3
1 (SC01), and according to the denomination discrimination, the coins fall from the sorting passage 1 through the discharge port 10 and are stored in the coin storage tube 16 for 1 yen coins. During this storage, the coins are detected by the passage sensor 41, and the detection signal ST1 is counted by the second counting memory 51 (STC1). Further, while the coin is falling, the near full sensor 61 provided at the top of the coin storage tube 16 is shielded from light as shown in time t1 to t2 in FIG. The clock pulse signal CLK is sequentially counted by "+1" in the third counting memory 71 (steps S1 to S5). Then, when the coin finishes passing through the near full sensor 61 (time t2), the pulse signal TC1 is no longer output because light passes through it.
The third counting memory 71 subtracts "-1" from the clock pulse signal CLK of the predetermined frequency (steps S1, S6, S7, S5). This subtraction continues until the third counting memory 71 reaches θ (time t3). The third counting memory 71 repeats addition and subtraction of the clock pulse signal CLK of a predetermined frequency as the near full sensor 61 blocks and transmits light due to storage of a 1 yen coin. At the time of storing the coins, the number of one yen coins determined by the identification sensor 2 and the denomination determining section 3 is counted in the first counting memory 31. When such counting is continued, the count value SC01 of the first count memory 31 and the count value of the second count memory 51
Both STC1 will gradually increase as shown in FIG. 3D.

Here, if the light shielding time of the stored coins continues to be longer than the transmission time for a long time, the added value will greatly exceed the subtracted value, and the counted value TC01 of the third counting memory 71 will finally exceed the limit value α1. (time t4). At this time, the third counting memory 71 outputs the latch signal LT1 to the management memory 81, and as shown in FIG.
is turned on (step S8), and the management memory 81 is
Read count value STC1 of count memory 51 and set RC01
At the same time, the judgment circuit 91
Input the count hold value RC01 into . The count value SC01 of the first count memory 31 is input to the determination circuit 91, and the determination circuit 91 determines whether the difference between the count value SC01 and the count value RC01 is less than or equal to the set value x1 (step S9). ), when the above difference reaches the set value x1 (time t5), the Nifl flag is activated as shown in Figure 3 E.
Turn on NFA1 and output (step S10).

When the near full flag NFA1 is turned on in this way and the coin storage cylinder 16 becomes full,
For example, by the method described below, coins of the relevant denomination that are being transported are stored separately.

Identification sensor 2 of classification passage section 1 and coin storage tube 1
A full coin storage cylinder is separately provided below between the coin storage cylinders 16 to 21, and after the coin storage cylinders 16 to 21 are full, the coins that have been conveyed are discharged from a discharge port separately provided in the sorting passage. Store separately. In this case, each denomination will be mixed and stored.

Coin storage cylinders 16 to 21 for each full coin storage cylinder
The coins of the denominations turned on by the near full flag are switched from the discharge port to the full coin storage cylinder and stored therein. In this case, each denomination is stored separately.

A full coin storage cylinder is provided at the most downstream of the sorting passage, and the coin storage cylinder with the near full flag turned on is closed from its discharge port, or a solenoid is operated to prevent coins from falling from the discharge port, Store it in a storage tube. In this case, it will be stored in mixed denominations.

In this way, the 1 yen coin with the near full flag NFA1 turned on is stored separately in the full coin storage tube, but when coins are released from this storage tube and the storage amount decreases, it is detected by the near full sensor 61. Since the number of 1 yen coins decreases and finally disappears, the count value TC01 counted in the third counting memory 71 also gradually decreases due to the subtraction operation, as shown in FIG. 3B.
The count value TC01 finally reaches ¨0'', and when it reaches ¨0'' (time t6), the near-full management flag NFK1 and the near-full flag NFA1 are turned on (step
S1, S6, S11, S12, S5). Therefore, it cannot be stored again. By the way, near full flag
With NFA1 turned on, more 1 yen coins will not be stored in the storage tube 16, and if the setting value x1 is set appropriately, 1 yen coins will exceed the storage tube 16. There isn't. The same applies to other denominations.

(Effects of the invention) As described above, according to the coin storage state detection device in the coin processing machine of this invention, when coins are stored in the storage sections provided for each denomination, the full state can be detected safely and reliably, and This has the effect of being able to be stored effectively.
