Description

  The present invention relates to a coin change machine, and more particularly to a coin change machine capable of efficiently performing a deposit process. Moreover, this invention relates to the control method of such a coin change machine.

  In cash registers such as supermarkets and convenience stores, banknote processing devices and coin processing devices connected to a host machine such as a POS system (point-of-sale information management system) are introduced (for example, see Patent Document 1). In the coin processing device disclosed in Patent Document 1, the coins that have been inserted into the slot and temporarily identified and counted are temporarily stored in the temporary storage unit, and then stored in the storage unit according to the denomination, and at the payout port. Coins are paid out as change. Further, the coins in the temporary holding unit can be directly returned (actual return) without going through the storage unit.

  A banknote processing apparatus and a coin processing apparatus can be used in two operations, ie, a deposit priority processing operation and a withdrawal priority processing operation (see, for example, Patent Document 2). In the deposit priority processing operation, first, money deposited from a customer is put into the apparatus, identified and counted in the apparatus, and temporarily held in a temporary holding unit. When the counted amount is approved, the money in the temporary holding part is accommodated in the denomination and the change money is withdrawn.

  On the other hand, in the withdrawal priority processing operation, the operator counts the deposit money from the customer, inputs the deposit amount by key, and dispenses the change currency. After the customer approves the change and the transaction ends, the deposited money is put into the device and stored in the denomination.

  When using a coin processing device as disclosed in Patent Document 1 in a withdrawal priority processing operation, the inserted coins are stored in the denomination storage unit after passing through the temporary storage unit. The conveyance path from the insertion slot to the denomination storage unit is increased by the amount that passes through the temporary storage unit, and it is necessary to issue a payment approval instruction to the temporary storage coin, which increases the time required for the payment process. Thus, the conventional coin processing apparatus has a problem that the deposit process cannot be efficiently performed according to each operation mode of the deposit priority process or the dispense priority process.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a perspective view showing a configuration of a coin change machine according to an embodiment of the present invention, and FIG. 2 is a schematic configuration diagram of the inside of the coin change machine shown in FIG.

  The coin change machine according to the present embodiment is connected to a control terminal comprising a POS register (a cash registering machine having a point-of-sale information management function). The control terminal registers product purchase information and causes the coin change machine to perform coin deposit / withdrawal processing. The control terminal is connected to the host server, and sales information and the like are transmitted from the control terminal to the host server.

  As shown in FIGS. 1 and 2, the coin change machine 1 includes a substantially rectangular parallelepiped casing 10 having an operation display unit 12 on the front upper surface. A front part of the housing 10 is provided with a receiving unit 14 into which coins are inserted from the outside of the housing 10 and a payout unit 16 for paying out coins.

  The receiving unit 14 takes in the inserted coins one by one in a one-layer one-row state. A first transport path 18 for transporting the taken coins extends behind the receiving unit 14.

  The coins conveyed on the first conveyance path 18 are identified and counted by the identification unit 20. The coins identified by the identification unit 20 are conveyed to the payout unit 16 through the second conveyance path 22 based on the identification result or the like, or to the collective storage unit 26 or the denomination storage unit 28 through the third conveyance path 24. Be transported. The specific coin transport destination will be described later.

  The coins conveyed to the dispensing unit 16 are dispensed out of the machine. Coins conveyed to the denomination storage unit 28 are stored in denominations. For example, the money type storage unit 28 includes a 1-yen coin storage unit 28a, a 5-yen coin storage unit 28b, a 10-yen coin storage unit 28c, a 50-yen coin storage unit 28d, a 100-yen coin storage unit 28e, and a 500-yen coin storage unit. 28f. The collective storage unit 26 can collectively store coins of one or more denominations.

  The collective storage unit 26 and the denomination storage unit 28 can throw out stored coins. Coins thrown out from the collective storage unit 26 and the denomination storage unit 28 are conveyed to the identification unit 20 through the fourth conveyance path 30. The coins identified by the identification unit 20 are conveyed to the payout unit 16 by the second conveyance path 22 or conveyed to the collective storage unit 26 or the denomination storage unit 28 by the third conveyance path 24. The specific coin transport destination will be described later.

  The control unit 32 controls each unit constituting the coin change machine 1.

  As can be seen from FIGS. 1 and 2, a transport unit (the first transport path 18 and the third transport path 24) that stores the coins inserted into the receiving unit 14 in the collective holding unit 26 or the denomination storage unit 28, and the collective unit The conveyance unit (the fourth conveyance path 30 and the second conveyance path 22) that dispenses the coins dispensed from the holding unit 26 or the denomination storage unit 28 from the dispensing unit 16 intersects at the front surface in the housing 10. It is provided as follows. Moreover, the identification part 20 is provided in this intersection.

  At the intersection, for example, the conveyance path circulates in a substantially rectangular shape, and coins are passed from the first conveyance path 18 and the fourth conveyance path 30 to the circulation conveyance path, and the coins identified by the identification unit 20 are Passed to the second transport path 22 and the third transport path 24. That is, the conveyance part (the 1st conveyance path 18 and the 3rd conveyance path 24) which stores the coin thrown into the acceptance part 14 in the lump reservation part 26 or the money type storage part 28, and the lump reservation part 26 or money type storage part. The transport part (the fourth transport path 30 and the second transport path 22) that pays out coins thrown out from the transporting part 16 has a common transport path on the front surface in the housing 10. An identification unit 20 is provided in the common conveyance path portion.

  The coin change machine 1 according to the present embodiment includes a temporary holding mode in which the received coins are temporarily stored in the collective storage unit 26 and then stored in the denomination storage unit 28, and the direct denomination storage unit without temporarily holding the received coins. It is possible to operate in two modes: a direct storage mode for storing in 28. In the temporary holding mode, the coin change machine 1 is used in a deposit priority processing operation that prioritizes the determination of the amount of deposited coins over the change dispensing process. In the direct storage mode, the coin change machine 1 is used in two types of operations: a withdrawal priority processing operation that prioritizes the change dispensing process over the amount determination of the deposited coin and the deposit priority processing operation.

  In the deposit priority processing operation in the temporary hold mode, first, coins received from customers are put into the receiving unit 14, identified and counted by the identifying unit 20, and temporarily held by the collective storage unit 26. When the counted amount is approved by the operator, the coins in the batch storage unit 26 are stored in the denomination storage unit 28 via the fourth transport path 30, the identification unit 20, and the third transport path 24. Further, change coins instructed from a control terminal (not shown) are thrown out from the denomination storage unit 28, and the payout unit 16 is passed through the fourth transport path 30, the identification unit 20, and the second transport path 22. Will be paid out.

  That is, in the deposit priority processing operation in the temporary hold mode, the batch storage unit 26 has the same function as the temporary hold unit.

  The direct storage mode is a mode for storing overflow coins in the batch storage unit 26 without using the batch storage unit 26 as a temporary storage unit.

  In the withdrawal priority processing operation in the direct storage mode, the operator counts the deposit coins from the customer and keys the deposit amount into the control terminal. And the change coin instruct | indicated from the control terminal machine is thrown out from the money-type storage part 28, and it pays out from the discharge part 16 via the 4th conveyance path 30, the identification part 20, and the 2nd conveyance path 22. After the customer approves the change and the transaction ends, the coins received from the customer are put into the receiving unit 14.

  The coins that have been inserted are identified and counted by the identification unit 20, and are directly conveyed and stored in the denomination storage unit 28 by the third transport path 24 without passing through the batch storage unit 26. The time required for the deposit process can be shortened because the transport path is shorter than in the case of storing in the denomination storage unit after passing through the temporary storage unit as in a conventional coin change machine.

  In the deposit priority processing operation in the direct storage mode, the operator deposits coins received from the customer into the receiving unit 14 without counting or inputting the amount, and the amount identified and counted by the identifying unit 20 of the coin change machine 1 is deposited. The amount is sent to the control terminal. Then, the change coin instructed from the control terminal is thrown out from the denomination storage unit 28 and is paid out from the payout unit 16. The identification / counting of coins inserted into the receiving unit 14, the storage route to the denomination storage unit 28, and the payout route from the denomination storage unit 28 to the payout unit 16 are the same as the above-mentioned withdrawal priority processing operation. And only the priority is different.

  A switching unit for switching between such modes and operations is provided in the operation display unit 12. In addition, the control terminal may switch modes and operations, and notify the control unit 30 of a switching instruction.

  Next, the transfer destination of the coins inserted into the receiving unit 14 at the time of deposit and replenishment will be described. Here, “at the time of deposit” represents a case where deposits and the like from a customer are inserted, and “at the time of replenishment” represents a case where coins for change are replenished to the money type storage unit 28.

  First, using the flow shown in FIG. 3, the coin transfer destination at the time of deposit in deposit priority processing operation in the temporary hold mode will be described. The coins inserted into the receiving unit 14 (step S301) are identified and counted by the identification unit 20 (step S302), and it is determined whether or not the coins cannot be normally identified (reject coins) (step S303). Coins (special coins) that can be normally identified are transported to the batch storage unit 26 (step S304). On the other hand, the coin determined to be a reject coin is conveyed to the payout unit 16 (step S311).

  When the counting result by the identification unit 20 is approved (step S305), all the coins in the batch storage unit 26 are thrown out (step S307), and the identification unit 20 performs identification and counting again (step S308). It is determined whether it can be stored one by one in the corresponding denomination storage unit 28, that is, whether it becomes an overflow coin (step S309). If it is not an overflow coin, it is stored in the denomination storage unit 28 (step S310), and if it is an overflow coin, it is conveyed to the payout unit 16 (step S311).

  If the counting result by the identification unit 20 is not approved (step S305), all coins in the batch storage unit 26 are thrown out (step S306) and conveyed to the payout unit 16 (step S311).

  Thus, the collective storage unit 26 functions as a temporary storage unit, and when the counting result is not approved, the input coins can be returned in kind.

  Next, using the flow shown in FIG. 4, the input coin transport destination at the time of replenishment of the deposit priority processing operation in the temporary hold mode will be described. The coins inserted into the receiving unit 14 (step S401) are identified and counted by the identifying unit 20 (step S402), and it is determined whether or not the coins cannot be normally identified (rejected coins) (step S403). The reject coin is conveyed to the collective storage unit 26 (step S404). Thereafter, all the coins transported to the collective storage unit 26 are thrown out from the collective storage unit 26 (step S405), identified and counted again by the identification unit 20 (step S406), and whether or not they are rejected coins again. Is determined (step S407). The coin determined to be a reject coin again is conveyed to the dispensing unit 16 (step S410). Here, the number of retries for identifying coins is one, but it may be two or more.

  It is determined whether or not the coins that can be normally identified by the identifying unit 20 can be stored in the denomination storing unit 28, that is, whether or not the coins become overflow coins (step S408). If it is not an overflow coin, it is conveyed to the denomination storage unit 28 (step S409), and if it is an overflow coin, it is conveyed to the payout unit 16 (step S410).

  In this way, the coins can be efficiently replenished by storing the reject coins in the collective storage unit 26 and performing the identification again.

  Next, with reference to the flow shown in FIG. 5, the coin transfer destination at the time of deposit in the withdrawal priority processing operation in the direct storage mode will be described. The coins inserted into the receiving unit 14 (step S501) are identified and counted by the identifying unit 20 (step S502), and it is determined whether or not the coins have been normally identified (step S503). It is determined whether or not the coins that can be normally identified by the identification unit 20 can be stored in the denomination storage unit 28, that is, whether or not the coins become overflow coins (step S504). If it is not an overflow coin, it is stored in the denomination storage unit 28 (step S505), and if it is an overflow coin, it is stored in the batch storage unit 26 (step S506).

  Also, coins (rejected coins) that could not be normally identified by the identifying unit 20 are stored in the collective storing unit 26 (step S506). In the withdrawal priority processing operation in the direct storage mode, the amount of key input by the operator to the control terminal is transmitted to the host server as the confirmed amount of deposit coins. Therefore, even if the identification unit 20 determines that the coin is a rejected coin, the coin is stored in the collective storage unit 16 without being paid out (not returned).

  Thus, normally identified coins are directly stored in the money type storage unit 28 without passing through the collective storage unit 26, so that the transport path is not longer than necessary and the time required for the deposit process is reduced. Can be shortened. Moreover, since overflow coins and reject coins can be stored in the batch storage unit 16, it is not necessary to separately provide an overflow coin storage unit and a deposit reject coin storage unit, and the apparatus cost can be reduced.

  Subsequently, the input coin transport destination at the time of replenishment of the withdrawal priority processing operation in the direct storage mode will be described using the flow shown in FIG. The coins inserted into the receiving unit 14 (step S601) are identified and counted by the identifying unit 20 (step S602), and it is determined whether or not the coins have been normally identified (step S603). It is determined whether or not the coins that can be normally identified by the identifying unit 20 can be stored in the denomination storing unit 28, that is, whether or not they become overflow coins (step S604). If it is not an overflow coin, it is stored in the denomination storage unit 28 (step S605), and if it is an overflow coin, it is stored in the batch storage unit 26 (step S606).

  Also, coins (rejected coins) that could not be normally identified by the identifying unit 20 are conveyed to the dispensing unit 16 (step S607).

  In this way, of the normally identified coins, the overflow portion is stored in the collective storage unit 26. By replenishing many coins of denominations that are often withdrawn in advance and storing the overflow in the collective storage unit 26, when the change is insufficient, the coins are drawn out from the collective storage unit 26 and loaded into the denomination storage unit 28. it can. Thereby, the replenishment frequency | count of a coin can be reduced.

  In addition, by paying out the coins (rejected coins) that could not be normally identified to the paying unit 16, the rejected coins can be inserted again into the receiving unit 14 as supplementary coins, and the supplemental coins are put to sleep in the aircraft. Therefore, it can be replenished so that it can be used as a change without fail.

  Next, with reference to the flow shown in FIG. 7, the coin transfer destination at the time of deposit in deposit priority processing operation in the direct storage mode will be described. The coins inserted into the receiving unit 14 (step S701) are identified and counted by the identifying unit 20 (step S702), and it is determined whether or not the coins have been normally identified (step S703). It is determined whether or not the coins that can be normally identified by the identifying unit 20 can be stored in the denomination storing unit 28, that is, whether or not the coins become overflow coins (step S704). If it is not an overflow coin, it is stored in the denomination storage unit 28 (step S705), and if it is an overflow coin, it is stored in the batch storage unit 26 (step S706).

  Further, coins (rejected coins) that could not be normally identified by the identifying unit 20 are conveyed to the dispensing unit 16 (step S707).

  In this way, of the normally identified coins, the overflow portion is stored in the collective storage unit 26. Since it is not necessary to provide a separate storage unit for storing overflow coins, the apparatus cost can be reduced.

  The overflow coins are stored in the batch storage unit 26, and the reject coins are paid out from the payout unit 16. Therefore, it is not confused whether the paid-out coin is an overflow coin or a reject coin, and it is possible to prevent an erroneous process from being performed on the paid-out coin.

  The coin transfer destination at the time of replenishment of the deposit confirmation operation in the direct storage mode is the same as that in the withdrawal priority processing operation shown in FIG.

  As described above, the coin change machine 1 causes the collective storage unit 26 to function as the temporary storage unit in the deposit priority processing operation in the temporary storage mode, and in the direct storage mode, the denomination storage unit 28 does not pass through the collective storage unit 26. Can store coins directly. Therefore, with the coin change machine according to the present embodiment, the deposit process can be efficiently performed according to the operation mode such as the deposit priority process and the withdrawal priority process.

  Further, in the direct storage mode, the overflow coins can be stored in the collective storage unit 26, so that the apparatus cost can be reduced as compared with the case where a storage unit for storing overflow coins is provided.

  Moreover, the conventional coin change machine was provided with the sensor which counts the number of the coins thrown out, and the sensor which measures a material at the throwing-out opening of a money storage part. By measuring the material of the coins to be thrown out, it is detected whether the coins thrown are the corresponding denominations, and the amount to be paid out is calculated and confirmed from the denomination and the number of thrown out coins. It was. That is, in the conventional coin processing apparatus, a sensor for measuring the material of the withdrawal coin and a sensor for counting the number of coins are provided in addition to the identification unit for identifying and counting the deposited coin.

  On the other hand, as shown in FIG. 2, the coin change machine according to the present embodiment is configured such that the coins thrown out from the denomination storage unit 28 pass through the identification unit 20 that performs identification and counting when depositing. There is no need to provide a sensor for measuring the material at the outlet of the money storage unit. Therefore, the device cost can be further reduced.

  In addition, since the same identification unit performs identification at the time of depositing and withdrawing, there is no difference in identification ability, and it is possible to prevent the occurrence of a situation where coins accepted at the time of deposit become indistinguishable at the time of withdrawal. . In addition, since it is only necessary to be able to confirm the denomination at the time of withdrawal, and it is not necessary to inspect whether or not it is a fake coin, the identification ability of the identification unit 20 at the time of withdrawal may be lowered. .

  You may make it utilize the package storage part 26 of the coin change machine which concerns on the said embodiment at the time of remaining collection | recovery. All coins in the denomination storage unit 28 are fed out, the remaining portion is conveyed to the collective storage unit 26, and the rest is conveyed to the dispensing unit 16. After all the coins are transported, by storing the coins in the collective storage unit 26 in the denomination storage unit 28, it is possible to realize the remaining collection of collecting more coins after leaving the necessary number of coins.

  Note that the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. In addition, various inventions can be formed by appropriately combining a plurality of components disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, constituent elements over different embodiments may be appropriately combined.
