Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coin discriminating and conveying device for conveying inserted coins and for discriminating denominations and the like at an identification section.

[0002]

2. Description of the Related Art Coins inserted from a coin insertion slot, into which a plurality of different types of coins can be put together, are sent out one by one by coin sending means, and the sent out coins are conveyed by the transfer means. 2. Description of the Related Art There is known a coin discriminating / transporting apparatus which conveys a coin to a coin sorting unit via a discriminating unit for discriminating a kind or the like, sorts coins by denomination in the coin sorting unit, and stores the coins in a coin storage unit.

In such a coin discriminating / transporting apparatus, it is a condition that only one coin faces the discriminating section in order to discriminate coins in the discriminating section. For this reason, when coins are continuously sent out by the coin sending means, an interval distance (hereinafter, referred to as an interval) in which only one identification unit can pass through the identification unit.
"Minimum required coin interval". ).

[0004] As means for providing the minimum necessary coin interval, coins fed from a coin feeding slot for forming a part of a coin sending means for sending coins inserted from a coin slot are fed. Means for increasing the feed speed of the conveyor belt which constitutes a part of the conveyor means for conveying the coins to the coin sorting section.

[0005] Theoretically, when the feeding speed of the input belt is α1 and the feeding speed of the transport belt is α2, the first coin transferred from the input belt to the transport belt is transported at the speed α2. Note that α2 (coin transport speed) is determined by the discriminating ability of the coin discriminating unit. On the other hand, the second coin, which has been fed with the input belt following the first coin,
The first coin is conveyed at a speed α1 lower than the speed α2. Assuming that a time t at which the second coin is transported from the input belt to the transfer point at which the second coin is delivered to the transport belt is t, this time t is t = W / α1 where W is the diameter of the second coin. Can be obtained by And
During this time t, the transport distance of the first coin from the delivery point on the transport belt can be obtained by t × α2. Therefore, the distance between the first coin and the second coin on the conveyor belt is (W / α1) × α2. Therefore, the feed speed α2 of the conveyor belt and the feed speed α1 of the feeding belt may be set such that the distance between the coins becomes the minimum necessary coin interval.

However, due to load fluctuations of the drive system caused by the use environment of the coin discriminating and conveying device, the feed speed of the conveying belt is reduced below the theoretical value, and the coin is conveyed due to the slip between the coin and the conveying belt. If the speed is lower than the feed speed of the conveyor belt, there may be a case where it is not possible to use only one coin facing the identification unit.

Therefore, conventionally, in consideration of the worst conditions of the use environment, the feeding speed α1 of the feeding belt is set to be slower than the required coin conveying speed so that the interval is longer than the minimum necessary coin interval. .

[0008]

As described above, conventionally, coins are conveyed by the conveying means at intervals longer than the required minimum coin interval by making the coin sending speed by the coin sending means slower. Therefore, as the number of inserted coins increases, the processing time required for transporting and identifying coins increases.

For this reason, when it is necessary to identify a large number of coins, it takes a long time to carry out the business. For example, when the coin discriminating and conveying device is applied to an automatic change dispensing device, the processing time becomes long. There was a concern that customer service would be degraded due to delays.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object to provide a coin discriminating and conveying apparatus capable of shortening a processing time required for conveying and discriminating a plurality of coins inserted from a coin insertion slot.

Coin sending speed determining means for determining a coin sending speed by the coin sending means so as to keep the coins sent by the coin sending means at the speed determined by the determining means. Is obtained and a control means for controlling the degree shifting means.

The payout motor 45 is a drive source of the storage belt 21 and the payout standby belt 25. The input motor 43 is variably driven to operate the input belt 8 at a speed set in a RAM 34 described later.

Here, the coin sorting plate 11 and the sorting belt 1
Reference numeral 8 denotes a coin sorting unit that sorts coins by denomination and stores the coins in the coin storage unit 20. The input belt 8 and the input roller 6 constitute a coin sending means for sending coins inserted one by one from a coin insertion slot capable of inputting a plurality of coins collectively. Conveyance path guide plate 11, first conveyance belt 12
The second transport belt 16 constitutes transport means for transporting the coins fed one by one by the coin insertion means to the coin sorting section. Further, the input motor 42 constitutes a speed changing means for changing the speed at which coins are sent out by the coin sending means (the input belt 8 and the input roller 6).

In the RAM 34, as shown in FIG.
When the insertion sensor 5 detects the insertion of a coin, the coin delivery speed α1, for driving the insertion belt 8, the first and second transport belts 12, 16 and the sorting belt 18 respectively, is used.
An initial speed table 51 in which the conveying speed α2 and the sorting speed α3 are set and stored is formed. Further, according to the coin transport speed Vc by the transport means, the coin delivery speed V1 at which the interval between the transported coins can keep the minimum coin interval Y necessary for identifying the coins by the identification unit 13 is set stepwise. The optimum speed table 52 is formed.

The optimum speed table 52 indicates that the coin transport speed Vc is β1, β2, β3, β
4, β5 (β1 <β2 <β3 <β4 <β5), and the coin feeding speed V1 of the insertion belt 8 is set to γ1, γ2, γ3, in accordance with the stepwise speed. γ4
It is set to be. The coin interval of the coins sent out by the insertion belt 8 set at such a speed is always the minimum coin interval Y required, or an interval slightly longer than that.

As shown in FIG. 6, the RAM 34 stores the feeding belt 8, the first and second transport belts 12 and 16,
And a speed memory 53 for storing the speed at which the sorting belt 18 is driven, the coin delivery speed V1, the transport speed V2, and the selection speed V3, and a counting memory 54 for storing the number of sheets counted for each denomination by the counting sensor 19. A memory area is formed.

The automatic change dispensing apparatus 1 configured as described above.
After the system is started by turning on the power, the CPU 32 monitors the input sensor 5. When the insertion sensor 5 detects that a coin has been inserted into the coin insertion slot 2, the CPU
32 executes the processing shown in the flowchart of FIG.

First, in ST (step) 1, the RAM 3
4, the coin sending speed α1, the conveying speed α2, and the sorting speed α3 set in the initial speed table 51 are read.
The areas of the coin output speed V1, the transport speed V2, and the sorting speed V3 in the speed memory 53 are overwritten respectively.

Thereafter, in ST2, the input motor 42, the transport motor 43, and the sorting motor 44 necessary for storing coins are activated. Then, the coin sending speed α1, the conveying speed α2, and the sorting speed α set in the speed memory 53.
3, the feeding belt 8, the first and second transport belts 12, 16
The driving of each motor is controlled by the motor drive control unit 46 so that the selection belt 18 is driven. Also,
At this time, the timer 37 is started in ST3.

In this state, the CPU 32 monitors a signal from the proximity sensor 7 as ST4. When the timer 37 detects that one coin has been fed by the action of the input belt 8 and the input roller 6 based on a signal from the proximity sensor 7 before the timer 37 times out, in ST5,
The timer 37 is reset once and then restarted.

Next, in ST6, the CPU 32 monitors signals from the pair of speed detection sensors 29a and 29b. The speed detection sensor 2 on the upstream side with respect to the coin transport direction
The measurement of the time of the clock circuit 36 is started by the signal from 9a, and the measurement of the time is ended by the signal from the speed detection sensor 29b on the downstream side. Subsequently, the coin transport speed Vc is detected from the measured time and the set distance X.

Next, at ST7, the detected coin transport speed Vc is used to determine the speed stage of the optimum speed table 52, and the coin delivery speed of the input belt 8 corresponding to the speed stage is calculated from γ1 to γ4. Select (decision means).
Then, the selected speed is overwritten on the coin sending speed α1 of the speed memory 53. Thus, for example, when γ1 is selected, the motor driving control unit 46 controls the insertion motor 43 so that the coin feeding speed of the insertion belt 8 is driven at the speed γ1 (control means).

Next, in ST8, the CPU 32 executes a denomination determination process on the single coin sent out. In this denomination determination processing, first, it is checked whether or not the conveyed article is a perforated coin (5 yen, 50 yen) based on a signal from the hole sensor 9. Next, it is confirmed that the transported object is shifted to the specified transport path, that is, the right edge of the transport path guide plate 11 by the signal from the offset sensor 10. Next, the outer dimensions of the conveyed object are checked by the identification unit 13 and compared with a predetermined value to determine whether or not the coin is a legitimate coin.

Here, if the external dimensions of the conveyed article do not match the prescribed value of a regular coin and it is judged that the article is a foreign object such as a fake coin, an exclusion target flag is set and this denomination judgment processing is terminated. I do.

When it is determined by the outer shape check of the conveyed article that the coin is a legitimate coin, the coin having the outer shape is a perforated coin (5 yen, 50 yen) or a coin without a hole (1 yen, 10 yen).
(100 yen, 500 yen, 500 yen). That is, in the case of a perforated coin, if no hole is detected by the hole sensor 9, the coin is a fake coin, so the exclusion target flag is set, and the denomination determination processing ends.

On the other hand, when a hole is detected by the hole sensor 9 in a holed coin and when a holeless hole is detected in a holeless coin, the coin is a denominated coin. The storage full sensor 22 is checked to determine whether or not overflow has occurred.
If the overflow has occurred, the exclusion target flag is set. If the overflow has not occurred, the denomination determination process is terminated without setting the exclusion target flag.

After the denomination determination processing is completed,
In ST9, the CPU 32 determines whether or not the conveyed object is an exclusion target. Here, if the exclusion target flag is not set, the conveyed object becomes a coin that can be stored in the coin storage unit 20 and is not excluded, and the second conveyance belt 16 and the sorting belt 1
8 and is stored in the coin storage unit 20.

On the other hand, when the exclusion target flag is set, the conveyed object is the exclusion target coin or foreign matter, and in ST10, the reject solenoid 14c is drive-controlled to open the reject shutter 14b.
As a result, coins or foreign matter to be excluded are removed from the reject port 14a and stored in the reject storage unit 30. Subsequently, in ST11, the CPU 32 monitors the signal of the reject sensor 15 and, when detecting a removed coin or foreign matter, controls the stop of the drive of the reject solenoid 14c to close the reject shutter 14b.
Thereafter, the exclusion target flag is reset.

The CPU 32 determines whether the exclusion target flag has not been set in ST9, or
When the closing operation of the reject shutter 14b is performed and the exclusion target flag is reset, the process returns to ST4.
The signal from the proximity sensor 7 is monitored, and the process described in ST5 to ST12 is repeated each time it is detected by the signal from the proximity sensor 7 that coins have been sent out one by one.

Thereafter, while monitoring the signal from the proximity sensor 7, the CPU 32 detects a timeout of the timer 37 in ST 13, and in ST 14, detects the timeout of the charging belt 8.
It is determined that the last coin sent out by the action of the insertion roller 6 is stored in the coin storage unit 20 and that all the coins inserted into the coin insertion slot 2 have been stored.
2. The transport motor 43 and the sorting motor 44 are stopped, and the process is terminated.

As described above, in the present embodiment, when a plurality of coins are inserted from the coin insertion slot 2, the coin to be conveyed first is fed into the insertion belt 8 operating at the coin sending speed α1.
The first conveyor belt 12 which is sent out to the conveyance path guide plate 11 by the action of the feeding roller 6 and operates at the conveyance speed α2
Through the speed detection sensor 29 and the identification unit 13
Is conveyed to the conveyance belt 16. And the feeding belt 8
Operates at a coin delivery speed corresponding to the coin transport speed Vc of the first coin, for example, if β3 <Vc <β4, the coin delivery speed γ3. As a result, the interval between the coins that are successively conveyed is always conveyed at the minimum necessary coin interval Y or a slightly longer interval. As a result, the identification unit 13 can reliably identify the coin.

However, before the transfer of all the inserted coins is completed, the transfer speed Vc of the coins may be reduced due to the influence of the slip between the coins and the first transfer belt 12.

When the coin transport speed Vc becomes slow as described above, the feeding belt 8 moves the coin transport speed Vc.
c, the optimal coin delivery speed corresponding to c, for example, β2 <V
If c <β3, the insertion motor 43 is controlled so that the insertion belt 8 operates at the coin delivery speed γ2. Therefore, even in such a case, the coins are transported at the minimum necessary coin interval Y or a slightly longer interval, so that the identification unit 13 can surely identify the coins.

Therefore, the interval between coins when conveying a plurality of inserted coins can always be brought closer to the minimum necessary coin interval Y, so that a plurality of coins can be identified and stored in the coin storage unit 20. Processing time can be shortened. As a result, the work of the operator can be performed quickly, and a decrease in customer service can be prevented.

(Second Embodiment) Next, a second embodiment will be described. The same parts as those in the first embodiment are denoted by the same reference numerals, and detailed description will be omitted. In the second embodiment, a calculation formula for calculating an optimum feed speed of the feeding belt 8 is set, and a speed detection sensor 29 is set.
Each time the speed of the coin is detected, the optimum feed speed of the feeding belt 8 is calculated by the above formula, and the feeding motor 42 is controlled by the motor drive control unit 46 so that the feeding belt 8 operates at that speed. Thus, the optimum speed table 52 of the first embodiment can be omitted.

The above equation shows that the coin transport speed detected by the speed detection sensor 29 is Vc, the minimum diameter of the coin for each denomination is Wa, and the minimum required for the identification unit 13 to identify a coin. Assuming that the interval between coins is Y and the speed at which coins are fed out of the insertion belt 8 is V1, V1 = (Wa / Y) × Vc (1)

The same effect as that of the above embodiment can be obtained in the coin discriminating / conveying apparatus thus configured.

Although the coin discriminating and conveying device of the present invention is applied to the automatic change dispensing device in both embodiments, the present invention is not limited to this.
Of course, various modifications can be made without departing from the spirit of the present invention.

[0058]

According to the invention described in each of the claims, the coin transport speed of the coins actually transported is detected, and the interval between the coins transported is always made closer to the minimum required coin interval based on the detected speed. Therefore, it is possible to provide a coin discriminating and conveying device capable of shortening a processing time for discriminating and conveying a plurality of coins inserted from a coin insertion slot.
