Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coin sorting device for sorting coins by denomination and storing them in a denomination storing unit.

[0002]

2. Description of the Related Art Conventionally, a coin sorting device generally dispenses coins, which are received in a mixed state of multiple denominations, one by one to an identification exclusion passage section by a delivery means such as a rotating disc, and the coins are removed in the identification exclusion passage section. While identifying the denomination while transporting, remove abnormal coins etc. according to the identification result,
Normal coins are passed through the coin discriminating and excluding passage portion and conveyed to the sorting passage portion, where coins are sorted by denomination in the sorting passage portion,
The sorted coins are stored in the storing section for each type of money. Further, the number of coins stored in each coin storing unit is counted and stored by the counting unit, and the full detecting unit detects whether each coin storing unit is full.

As the fullness detecting means, a pair of photosensors whose optical axis passes through a predetermined position of the denomination-specific storage section is provided for each denomination-specific storage section, and each photosensor is selected depending on which optical sensor the optical axis is shielded. It is designed to detect the full state of the money type storage unit. In this way, the purpose of detecting the full state of the denomination-type storage unit by the photo sensor is to prevent the coins already stored when storing coins from interfering with the storage of coins that are about to be stored This is to prevent it from overflowing from the money type storage unit.

[0004]

However, in the conventional coin sorting device, the number of coins stored in each coin storing unit is counted and stored by the counting means, and how many coins are stored in each coin storing unit. Despite storing whether coins are stored, a photo sensor is provided for each denomination-based storage unit, which is not economical.

However, if it is attempted to detect the full state only by the number of stored coins stored in the counting means, there are differences in the size of the coins, the state of the coins stored, for example, the state where the coins are piled up at a certain place and relatively evenly stored. However, since the storage amount is extremely different and it is difficult to accurately detect the full state that hinders the storage of coins, it is necessary to detect the full state with a photo sensor.

The present invention has been made in view of such a point, and it is possible to detect which of the denomination-specific storage sections is full by using only one photosensor. An object of the present invention is to provide a coin sorting device that can be simplified and reduced in cost.

The stopper means 61 is evacuated from the passage and the temporarily held coins are conveyed to the downstream side, sorted by the denomination in the sorting passage portion 13 and sorted and stored in the denomination storing portion 112, and the temporarily held coins are upstream by the return instruction. It has the function of being conveyed to the side and being rejected by the rejection passage portion 14 and returned. Further, the identification unit 45
When the coins that can be deposited are identified in the temporary storage passage portion 15 by a predetermined number that can be temporarily stored, the second stopper means 46 is advanced to the passage and the conveyance of the deposited coins is temporarily stopped and temporarily held. After the temporary holding coins are sorted and stored in the denomination storing unit 112 according to the deposit approval instruction for the deposited coins, the second stopper means 46 is retracted from the passage and the depositable coins among the remaining deposited coins are stored. Temporary holding passage section
It has a function to temporarily hold at 15.

Further, the control section 181 controls the photo sensor S21,
When S22 is shielded from light and a full state is detected, the ratio of the current number of stored coins to the maximum number of coins stored for each coin type storage unit 112 is calculated, and it is determined that the coin type storage unit 112 with the largest ratio is full. It has the function of the department.
Further, the abnormality detection unit has a function of determining an abnormality when the ratio of the current number of stored sheets to the maximum number of stored sheets of the money type storage unit 112 which is determined to be full is less than a predetermined value (for example, 70%). is doing. Further, a predetermined number of coins are paid out and collected in the denomination type storing unit 112, which is determined to be full by the full detecting unit, and
If the photo sensors S21 and S22 are shielded from light even after performing the collecting process for the one denomination storing unit 112 and the full state is detected, the ratio of the current number of stored sheets to the maximum number of stored sheets is the second largest. It has a function of a recovery control unit that causes the unit 112 to perform recovery processing.

Next, the operation of this embodiment will be described.

In this embodiment, the denominations to be processed are all denominations, 1 yen and 5 yen are selected in the electrical sorting sections 73 and 74, and coins of all denominations are stored in the denomination storing section 112. Is stored.

First, the deposit process under the control of the control unit 181 will be described.

The operator issues a deposit command through the operation unit 183 and inserts coins into the deposit port 2. The coins inserted into the deposit port 2 are guided onto the rotating disk 5 through the hopper 3.

In response to the deposit command, the motors M1, M2, M3, M7 are respectively driven to rotate in the normal direction, and the rotating disk 5 and the conveyor belt 2
While 6, 27 and 28 are rotated in the forward direction,
The return belt 102 is rotated (the withdrawal belt 151 is also rotated). Further, the solenoid SD4 of the first stopper means 61 is operated and the pin 62 is advanced (raised) in the passage.

As a result, the coins on the rotary disk 5 move along the peripheral wall 7 by the centrifugal force generated by the rotation of the rotary disk 5, and the coin passage 11 is opened from the unillustrated outlet opening in the peripheral wall 7.
Are sequentially fed out to the introduction passage portion 12 in the state of one layer and one row.

The coins fed into the introduction passage portion 12 are taken into the introduction passage portion 12 at a high speed by the take-in roller 41, and are gripped below the conveyor belt 26 so that the passage surface
While being pressed against 21, it is conveyed to the downstream identification passage portion 13. At this time, due to the take-in operation of the take-in roller 41, a space is provided between the coin and the coin that is subsequently fed from the rotary disc 5 into the introduction passage portion 12, and thus a space in the longitudinal direction of the coin in the coin passage 11 is formed. .

The coins conveyed through the identification passage portion 13 are
It is identified by 45 and is conveyed to the downstream exclusion passage portion 14.

When the identifying unit 45 identifies a coin that can be deposited in the denomination to be processed, it is not forcibly removed by the electrical rejecting unit 54 of the rejecting passage unit 14 and the downstream temporary holding passage unit is not forcibly removed. Transported to 15. That is, the coins conveyed by the conveyor belts 26 and 27 come into contact with the guide edge portion 52 and are brought close to the center of the passage, then move along the reference edge portion 51 and pass over the exclusion hole 55, and the It is transported to the temporary storage passage section 15.

If the identification unit 45 identifies a coin that cannot be deposited (otherwise referred to as a reject coin) other than the denomination to be processed, it is forcibly removed by the electrical exclusion unit 54 of the exclusion passage unit 14. It That is, when the rejected coins conveyed by the conveyor belts 26 and 27 are detected by the sensor S1, the solenoid SD2 of the upstream side removing means 56 is operated and the pin 58 is advanced (raised) onto the passage, and the rejected coin side is moved. The edge is a pin
Abutting 58, the center of the passage, that is, the reference edge of the reject coin
One side edge facing 51 is brought close to the exclusion hole 55,
When one side edge of the reject coin reaches the exclusion hole 55,
The rejected coins are dropped and removed from the exclusion hole 55. After the rejected coins are removed, the operation of the solenoid SD2 is stopped and the pin 58 is retracted (lowered) from the passage.

The reject coin dropped from the exclusion hole 55 is guided to the return belt 102 through the receiving frame 101, discharged to the tray 105 by the return belt 102, and returned to the operator.

The depositable coins conveyed to the temporary storage passage portion 15 come into contact with the pin 62 of the first stopper means 61 and are stopped, and the succeeding depositable coins come into contact with the stopped coins. Will be stopped. Therefore, the depositable coins are temporarily held along the passage of the temporary holding passage portion 15.
However, the number of coins that can be temporarily held is limited to within a predetermined number, and the number of temporarily held coins is counted according to the identification result of the identification unit 45.

If the number of temporarily reserved sheets is within a predetermined number, the identification unit 45
When a predetermined time elapses after the coins are no longer detected, the motors M1, M2, M3, and M7 are stopped, assuming that all the coins inserted into the deposit port 2 have been removed or temporarily held.

Then, the result identified by the identifying unit 45 is displayed on the display unit 184. When the operator confirms this and approves the deposit, the operation unit 183 operates the deposit approval instruction.

At the time of deposit approval, the motors M2, M3, M4 are driven to rotate in the normal direction, and the conveyor belts 26 to 30 are rotated in the normal direction. Further, the operation of the solenoid SD4 of the first stopper means 61 is stopped and the pin 62 is retracted (lowered) from the passage.

As a result, the coins temporarily held in the temporary holding passage portion 15 are conveyed to the downstream connecting passage portion 16 and the sorting passage portion 17.

The coin conveyed to the sorting passage portion 17 comes into contact with the guide edge portion 71 and is brought to the center of the passage, and then the reference edge portion.
Transported along 71. Then, among the coins conveyed through the sorting passage unit 17, 1-yen and 5-yen denomination coins are sorted by the electrical sorting units 73 and 74, and the remaining denomination coins are respectively sorted by the shape sorting units 75 to 78. Be sorted.

In each of the electric sorting sections 73 and 74, the order and coin type of the temporarily held coins are stored. Therefore, when the corresponding coin type coins are detected by the sensors S3 and S4, the solenoid SD5, SD6 is actuated and the pin 85 is advanced (raised) into the passage, the coin of the corresponding denomination makes contact with the pin 85, and the center of the passage, that is, the one side edge facing the reference edge 71 of the coin of the denomination is the sorting hole. When the coins of the relevant denomination coin are brought to the sorting holes 81 and 82, the coins of the relevant denomination coin are dropped and sorted from the sorting holes 81 and 82. After sorting the coins of the denomination, the operations of the solenoids SD5 and SD6 are stopped and the pin 85 is retracted (lowered) from the passage.

In the shape selection sections 75-78, coins are selected in the selection holes 91-
When passing through the denomination coin 94, the edge of the coin of the corresponding denomination coin opposite to the reference edge 71 falls into the sorting holes 91 to 94 and is dropped and classified. Passed to the downstream side while remaining on both side edges. Selection hole for coins of the relevant denomination 91
The selection to ~ 94 is confirmed by the detection of the sensors S5 to S8.

The coins sorted by the sorting holes 81, 82, 91 to 94 fall in the chute 111 and are stored in the storing section 112 for each type of denomination. A chute 11 is provided in each gold type storage unit 112.
The coins falling inside 1 are stored in the upper storage unit 121 of the upper storage unit 113.
Will be accepted and stored by. Selection holes 81, 82, 91 to 94
Every time the relevant denomination coin is selected, the storage unit 182 increments the current number of stored coins in the upper storage unit 121 by +1.

When the sorting of all the temporarily held coins is completed, the motors M2, M3, M4, M7 are stopped, and the next deposit / withdrawal processing is ready to be performed.

Further, since the number of deposited coins inserted into the deposit port 2 is large, the discriminator 45 temporarily deposits coins that can be deposited.
When the predetermined number of sheets that can be temporarily held is identified at 15, the conveyance of the deposited coin is temporarily stopped by the second stopper means 46 of the identification passage portion 13. That is, the solenoid SD1 of the second stopper means 46 is actuated to advance (raise) the pin 47 into the passage, and the coin deposited is brought into contact with the pin 47 and temporarily stopped. Depositable coins passing through the position of the second stopper means 46 are temporarily held in the temporary holding passage portion 15.

Then, with respect to the deposited coins temporarily held, the result identified by the identification unit 45 is displayed on the display unit 184, and guidance such as being a part of the deposited coins is displayed. When the operator confirms this and approves the deposit, the operation unit 183 operates the deposit approval instruction.

According to the deposit approval instruction, as described above, the temporary holding coins of the temporary holding passage portion 15 are conveyed to the sorting passage portion 17 and sorted by denomination, and are stored in the denomination storing portion 112 by denomination. .

After the completion of the selection of the temporarily held coins, the operation of the solenoid SD1 of the second stopper means 46 is stopped, the pin 47 is retracted (lowered) from the passage, and the transfer of the remaining deposited coins is restarted. Deposit processing such as is performed.

Further, the deposited coin is temporarily held, and the identification unit 45
When the operator desires to return the deposited coins after displaying the result identified by the display unit 184, the operation unit 183 performs a return instruction operation.

At the time of returning, the motors M2 and M3 are driven in reverse, the motor M7 is driven in forward, the conveyor belts 26 to 28 are rotated in the reverse direction, and the return belt 102 is rotated (withdrawal belt 151). Is also rotated at the same time).

As a result, the temporary holding coins in the temporary holding passage portion 15 are conveyed to the upstream elimination passage portion 14 and are removed.
It is forcibly removed by the electrical exclusion unit 54. That is, the coins conveyed by the conveyor belts 26, 27 are
When it is detected by the sensor S2 after coming into contact with the 53 and being brought to the center of the passage, the solenoid SD3 of the downstream side removing means 57 is detected.
Is operated and the pin 58 is advanced (raised) onto the passage, the coin abuts on the pin 58 and the center of the passage, that is, the reference edge portion 51 of the coin.
When one side edge of the coin reaches the exclusion hole 55, the one edge of the coin is pulled over the exclusion hole 55, and the coin falls and is removed from the exclusion hole 55. The solenoid SD3 may be operated and stopped each time a coin is detected by the sensor S2, or the operating state may be continued until all the temporarily held coins are removed.

The coins dropped from the exclusion hole 55 are guided to the return belt 102 through the receiving frame 101, discharged by the return belt 102 to the receiving tray 105, and returned to the operator.

After returning the coins, the motors M2, M3, M7 are stopped, and a standby state in which the next deposit / withdrawal process can be performed is made.

Further, the upper side storage part 121 of the denomination-based storage part 112
The coins stored in the lower storage unit 141 are preferentially stored so that a predetermined number or more of coins are always stored in the lower storage unit 141 in preparation for the withdrawal process described later. ing. In other words, while the number of stored sheets is small, even if they are stored in the upper side storage section 121, they are not stored in the upper side storage section 121 but are stored in the lower storage section 141. When a predetermined number or more of coins are stored in the lower storage unit 141, the upper storage unit 121 becomes full, or the lower storage unit 141 stores the coins in the upper storage unit 121 until the number of coins becomes equal to or smaller than a predetermined number. .

When the upper storage 121 is full, the photo sensor S21 is shielded from light and the full state is detected. Upon receiving this full detection, the control unit 181 performs the full coin collection process.

The full coin recovery process under the control of the control unit 181 will be described with reference to the flowchart of FIG.

The collected flag of the denomination in the storage unit 182 is cleared (step 1), and the ratio of the current stored number to the maximum stored number based on the storage of the upper storage unit 121 of each denomination-based storage unit 112, that is, The storage rate M is obtained, and it is determined that the upper side storage section 121 of the denomination-based storage section 112 having the largest storage rate M is full (step 2).

Further, the storage rate M is a predetermined value, for example, 7
It is judged whether it is 0% or more (step 3).
That is, if the actual number of stored sheets is small despite the detection of the full state, for example, the upper storage section 12
It is judged that an abnormality such as a coin jam has occurred in 1 and error processing such as notifying the staff is performed.

A predetermined number of coins (which can be arbitrarily set) are dispensed in the coin type storing unit 112 which is determined to be full (step 4). That is, the motor M5 on the side of the upper side storage body 113 of the money type storage unit 112 is driven, and all the upper side storage bodies are driven.
The feeding belt 123 of 113 is integrally rotated, and the reverse rotation roller 129 is reversely rotated. In each upper side storage body 113 of the gold type storage portion 112, the pin 134 of the stopper mechanism 131 is usually used.
Is in a state where it has advanced to the feeding passage 133 and stopped feeding coins, and the upper storage 113 of the relevant denomination judged to be full, and the solenoids SD7 to SD12 of the stopper mechanism 131.
Is activated to retract the pin 134. Therefore, for the applicable denomination that is judged to be full, the feeding belt 123
By the action of the reverse rotation roller 129, the coins stored in the upper storage portion 121 are fed out one by one in a state of one layer and one row, and are thrown out from the delivery outlet 127 to the lower storage portion 141. When coins are thrown out, they are detected by sensors S9 to S14
The storage unit 182 of 181 subtracts -1 from the current number of coins stored in the upper storage unit 121 and adds +1 to the current number of coins stored in the lower storage unit 141. For denominations other than the corresponding denomination that is judged to be full, the stopper mechanism
Since 131 is kept in a stopped state, the denomination coins are not thrown out even when the feeding belt 123 is rotated.

In this way, a predetermined number of coins are transferred from the upper storage unit 121 to the lower storage unit 141 (step 5), but if a coin jam occurs during the full coin recovery process, a staff member is informed. Error processing such as performing is performed.

When a predetermined number of coins are normally transferred from the upper storage section 121 to the lower storage section 141, the collected flag of the corresponding denomination is set in the storage section 182 (step 6), and the photo sensor S21 transmits light. If it becomes a state (step 7), the motor M5
Is stopped and the operations of the solenoids SD7 to SD12 are stopped, and the full coin recovery process is ended.

Further, when the photosensor S21 is shielded from light and the full state is detected even after the collection operation is performed on the upper side storage section 121 of the one money type storage section 112,
It is determined whether or not the full coin collection process has been performed for all denominations (step 8).

If the full coin collecting process has not been performed for all denominations, the process returns to step 2 and the denomination storing unit 11 has the second largest storage ratio M of the current stored number to the maximum stored number.
A similar full coin recovery process is performed for the second upper storage portion 121.

Even if the full coin collecting process is performed for all denominations, if the photo sensor S21 is in a light-shielded state due to an abnormality or the like, an error process such as notifying a staff member is performed.

Further, the coin lower storage portion of the upper storage portion 121
When the lower storage unit 141 of any of the denomination-based storage units 112 becomes full due to the storage in 141, the photo sensor S22 is shielded from light and the full state is detected. Also in this case, as in the full coin recovery process in the upper storage 121, the control unit 181
It is determined that the lower storage unit 141 of the denomination-based storage unit 112, which has the largest storage ratio M of the current stored number to the maximum stored number, is full, and the lower-side storage unit 141 of the denomination-based storage unit 112 that is determined to be full. About a predetermined number of coins are paid out. In this case, as will be described later in a collecting process, the coins paid out from the lower storage unit 141 are
It is collected in the collection cassette 174 through the distribution plate 172 and the chute 173.

Next, the withdrawal process under the control of the control unit 181 will be described.

The operator inputs coin withdrawal data (amount, denomination and number of coins, etc.) on the operation unit 183 to issue a withdrawal command, or automatically subtracts the sales amount from the deposit amount to obtain the difference amount. Is calculated, and when a change dispensing command is issued, the dispensing process is started.

The motor M6 on the lower side accommodating body 114 side of the money type accommodating portion 112 is driven, and the feeding belts of all the lower side accommodating bodies 114 are fed out.
The reverse rotation roller 129 is reversely rotated while the 123 is integrally rotated. At the same time, the motor M7 is driven and the withdrawal belt
151 is rotated.

In each lower housing 114 of the denomination-based housing unit 112, the pin 134 of the stopper mechanism 131 is normally provided with the feeding passage 133.
In the state where the coins are stopped to be paid out, the solenoids SD13 to SD18 of the stopper mechanism 131 of the lower storage body 114 of the denomination applicable to the dispensing are operated to retract the pin 134. Therefore, the payout belt 12
By the action of 3 and the reverse rotation roller 129, the coins stored in the lower storage portion 141 are fed one by one in a state of one layer and one row, and the horizontal conveying portion 157 of the dispensing belt 151 is fed from the feeding outlet 127.
Thrown on. When coins are thrown out, sensor S15 ~
The number of coins dispensed by denomination is counted in the storage unit 182 of the control unit 181 and detected at S20, and the current number of coins stored in each lower storage unit 141 is decremented by -1. Note that for denominations that do not correspond to the denomination denomination, the stopper mechanism 131 is kept in a stopped state, so that the denomination coin is not ejected even if the feeding belt 123 is rotated.

When the number of coins to be withdrawn according to the coin type counted in the storage unit 182 of the control unit 181 reaches the number of coins to be withdrawn for withdrawal, the sensors S15 to S20 pass the coins corresponding to the coin withdrawal number. When the coin is detected, the stopper mechanism 131 stops the coin next to the number of dispensed coins, and stops the coins of this denomination. With each denomination, the ejection of coins is similarly stopped each time the ejection is completed.

The coins thrown from the coin-type storing unit 112 onto the horizontal conveying unit 157 of the dispensing belt 151 are conveyed to the horizontal conveying unit 157 and the ascending conveying unit 158, and are withdrawn to the tray 105.

When all the coins corresponding to the amount of money to be dispensed have been dispensed from the coin-type storing unit 112, the motor M6 is stopped, and after the coin-type storing unit 112 has been completely dispensed, the horizontal transport unit 15
After a predetermined period of time sufficient for the above coins to reach the receiving tray 105, the motor M7 is stopped and a standby state in which the next deposit / withdrawal process is possible is performed.

Also, the lower storage body 114 of the denomination-based storage portion 112
When the amount of coins stored in the lower storage unit 141 is reduced to a predetermined amount or less by throwing out coins from the above, coins are replenished from the upper storage unit 113 to the lower storage unit 114. This lower compartment
The fact that the coin storage amount of 141 is reduced to a predetermined amount or less is managed by the current number of stored coins stored in the storage unit 182 of the lower storage unit 141.

In the replenishing operation, the motor on the side of the upper housing 113 is
The M5 is driven, and the feeding belt 123 of all the upper housings 113 is driven.
And the reverse rotation roller 129 reversely rotate, and the stopper mechanism 13 of the upper storage body 113 of the replenishment applicable denomination is
1 is released. As a result, in the denomination to be replenished, the coins stored in the upper storage 121 are fed one by one in a one-layer one-row state by the action of the feeding belt 123 and the reverse rotation roller 129, and the coins are fed from the feeding outlet 127. Lower housing
It is stored in the lower storage part 141 of 114. When the replenishment of coins from the upper container 113 to the lower container 114 is completed, the stopper mechanism 131 is returned to the stopped state and the motor M5 is stopped.

Next, the recovery process under the control of the control unit 181 will be described.

In response to the recovery command, the motors M7 and M8 are driven, the dispensing belt 151 is rotated, and the distribution plate 172 is used.
Is advanced onto the horizontal transport section 157 of the dispensing belt 151. Further, the motors M5 and M6 are driven, and the solenoids SD7 to SD of the stopper mechanism 131 of all the denomination-specific storage sections 112 are driven.
18 is activated and the coins in the upper storage 121 are
At the same time, the coins in the lower storage unit 141 are thrown out to the horizontal conveying unit 157 of the dispensing belt 151. Withdrawal belt 151
The coins thrown into the horizontal transfer section 157 are collected by the collecting cassette 174 through the distribution plate 172 and the chute 173. When coins are ejected from the lower storage unit 141, the sensor S15
Detected in S20, the storage unit 182 subtracts -1 from the current number of coins stored in the coin storing unit 112.

When it is confirmed that the current number of coins stored in all the coin storing units 112 is 0 and all coins have been thrown out, the motors M7 and M8 are stopped and the solenoids are stopped after a predetermined time. The operations of SD7 to SD18 are stopped, and the collection process is completed.

As described above, one of the denomination storing units 11
2 becomes full, and when the photo sensors S21 and S22 whose optical axis passes through the denomination-specific storage unit 112 in the parallel direction of the denomination-specific storage unit 112 are shielded from light, the full state is detected.
By the function of the full detection unit of the control unit 181, each money type storage unit
For 112, the ratio of the current number of stored coins to the maximum number of stored coins is calculated, and it can be determined that the denomination-based storage unit 112 with the largest ratio is full. By using only one photo sensor S21 and one photo sensor S22, respectively, it is possible to use the gold type storage unit 112.
It is possible to detect which of the denomination-specific storage units 112 is full, and it is possible to simplify and reduce the cost.

If the ratio of the current number of stored coins to the maximum number of coins stored in the coin type storage unit 112, which is determined by the abnormality detection unit of the control unit 181, that the full detection unit of the control unit 181 is full, is below a predetermined value. , It can detect that it is not full but abnormal, and error processing can be performed.

Further, the collection control unit of the control unit 181 causes the predetermined number of coins to be fed out and collected in the denomination storing unit 112 which is determined to be full by the full detection unit of the control unit 181. The 112 full condition can be cleared.

In addition, the recovery control section of the control section 181 sets 1
If the photo sensors S21 and S22 are shielded from light even after performing the collecting process for the one denomination storing unit 112 and the full state is detected, the ratio of the current number of stored sheets to the maximum number of stored sheets is the second largest. Since the collection process is performed on the part 112, even if the plurality of money type storage parts 112 are full, they can be sequentially solved.

In the above-described embodiment, the denomination-specific storage unit 11
Although the upper storage section 121 and the lower storage section 141 are separately provided in FIG. 2, they may have an integrated storage section structure, and in this case, the same operational effect can be obtained.
