Description

Coin feeder

The present invention relates to a coin supply device that stores coins and supplies coins to a feeding unit that feeds out the stored coins.

In a financial institution or a store, a coin processing machine such as a coin depositing machine for depositing and receiving coins, a coin depositing and dispensing machine for depositing and dispensing coins, and a coin wrapping machine for packaging coins are used.

In such a coin processor, a coin input from the outside is once received in a coin supply device, a coin is supplied from the coin supply device to a feeding portion, and coins are fed one by one from the feeding portion to a coin passage. Processing such as identification and classification of coins is performed in the passage.

As a conventional coin supply device, an input part is arranged below the input port for inputting coins from the outside, an input port shutter can be opened and closed at the input port, and a supply shutter can be opened and closed at the bottom of the input unit There is a configuration provided. In the coin supply device of this configuration, when depositing coins, the input shutter is opened with the supply shutter closed, and after the coins input from the input port are received by the input unit, the input shutter is closed. After that, the supply shutter is opened, the coins in the insertion unit are freely dropped, and the coins are collectively supplied to the feeding unit arranged below the insertion unit (for example, see Patent Document 1).

By the way, when a large amount of coins is supplied from a coin supply device to a feeding unit that feeds out coins one by one, a feeding failure that makes it impossible to feed out coins at the feeding unit occurs, and this feeding failure occurs. Then the coin processor stops.

In the coin supply device configured using the input port shutter and the supply shutter described above, the amount of coins supplied to the feeding unit at a time is limited to the capacity of the space in the input unit partitioned by the input port shutter and the supply shutter. It is possible.

Therefore, if the capacity of the coins that can be received by the input section is within the capacity of the coins that can be stored and fed out by the feeding section at a time, the occurrence of defective feeding in the feeding section can be reduced. However, if you want to throw in a large amount of coins that exceeds the capacity of the coins that can be stored and delivered by the feeding unit at one time, put some of the large number of coins to be thrown into the feeding unit and throw it in When coins are supplied from the department to the feeding section and the coins can be accepted into the throwing section, it is necessary to repeat the coin throwing operation many times, such as inserting some or all of the remaining coins. .

Conversely, if the capacity of the coins that can be received in the insertion part is larger than the capacity of the coins that can be stored and delivered by the feeding part at one time, it is not necessary to repeat the coin insertion operation. A large amount of coins is supplied from the unit to the feeding unit at a time, and a feeding failure in the feeding unit is likely to occur.

In addition, as another coin supply device, an insertion portion is arranged below the insertion port for inserting coins from the outside, and an insertion port shutter is provided at the insertion port so that it can be opened and closed. There is a configuration in which a conveyor for feeding in a direction is provided. In the coin supply device of this configuration, when depositing coins, the slot shutter is opened, the coins inserted from the slot are received in the slot, and the conveyor is operated after closing the slot shutter. In this conveyor, the coins in the input unit are fed out in the horizontal direction, and the coins are supplied to the feeding unit arranged on the side of the input unit. At this time, the amount of coins supplied to the feeding unit is detected, and coins on the conveyor are supplied to the feeding unit by a predetermined amount according to the detected amount of coins (see, for example, Patent Document 2).

Therefore, if the capacity of the coins that can be received in the insertion part is made larger than the capacity of the coins that can be stored and delivered by the feeding part at one time, it is not necessary to repeat the coin insertion operation many times. By controlling the supply amount of coins, it becomes difficult to cause a feeding failure in the feeding unit. However, since the coins in the input unit are sent out in the horizontal direction by the conveyor, it is necessary to arrange the feeding unit on the side of the input unit. As a result, a space for arranging the coin supply device and the feeding device in the horizontal direction is required in the coin processor, and the coin processor is enlarged in the horizontal direction, and the space required for installing the coin processor is large. turn into.

Supplied to the unit 32. Since the amount of coins supplied to the feeding unit 32 is limited by the opening amount of the bottom opening 39 of the insertion unit 37, the coins are fed little by little without being supplied to the feeding unit 32 in a lump. To be supplied.

The feeding unit 32 receives and stores the coins supplied from the input unit 37 in the hopper 66, and feeds the coins stored by the rotation of the rotary disk 65 to the coin passage 33 one by one.

Then, unless the coin amount detection unit 74 detects that the amount of coins stored in the feeding unit 32 has reached the storage limit capacity, the opening movement of the supply shutter 38 is continued.

Further, if it is detected by the coin amount detection unit 74 that the amount of coins stored in the feeding unit 32 has reached the storage limit capacity, the opening movement of the supply shutter 38 is decelerated or the supply shutter 38 is stopped until the detection is lost. Or the supply shutter 38 is moved in the closing direction to reduce the supply amount of coins to the feeding unit 32 or the supply of coins to the feeding unit 32 is stopped. Let If the coin amount detection unit 74 does not detect that the amount of coins stored in the feeding unit 32 has reached the storage limit capacity, the normal supply shutter 38 is returned to the opening movement.

In this way, the supply shutter 38 is opened, and all the coins in the insertion unit 37 are supplied to the feeding unit 32 by an appropriate amount. After the supply shutter 38 is fully opened, it is moved to the closed position.

Since the coin supply device 31 is configured to supply the coins in the input unit 37 to the supply unit 32 by opening the supply shutter 38 that opens and closes the bottom surface of the input unit 37, the supply unit 32 is provided below the coin supply device 31. The horizontal space required for these installations can be reduced.

Furthermore, since the capacity of coins that can be accepted by the insertion unit 37 is larger than the capacity of coins that can be stored and fed out by the feeding unit 32 at a time, the capacity of coins that can be stored and fed out by the feeding unit 32 at a time is exceeded. A large amount of coins can be input into the input unit 37 at a time, and the coin input operation does not have to be repeated many times.

Further, even after the coins are fed out from the feeding unit 32, the supply shutter 38 is moved continuously or intermittently so that the coins received on the supply shutter 38 fall on the feeding unit 32. Coins can be prevented from remaining on the shutter 38.

The required time for moving the supply shutter 38 from the closed state to the open state is controlled to be longer than the required time for moving the supply shutter 38 from the open state to the closed state. An appropriate amount of coins 37 can be supplied to the feeding unit 32.

Moreover, when the supply shutter 38 is opened and the coins in the insertion unit 37 are supplied to the supply unit 32, the opening amount of the supply shutter 38 is controlled according to the coin amount of the supply unit 32 detected by the coin amount detection unit 74. Therefore, an appropriate amount of coins can be supplied to the feeding unit 32 so that a feeding failure in the feeding unit 32 does not occur.

If the coin amount of the feeding unit 32 is detected by the coin amount detection unit 74 to be equal to or greater than the storage limit capacity, any one of the deceleration of the opening movement of the supply shutter 38, the stop of the opening movement, and the movement in the closing direction is selected. By controlling to one, it is possible to prevent coins in the insertion unit 37 from being supplied to the feeding unit 32 at a time, and to keep the amount of coins in the feeding unit 32 at an appropriate amount.

In addition, after the insertion port shutter 18 is provided and the insertion port shutter 18 is closed, the supply of coins to the feeding unit 32 is started. If there is no slot shutter 18, the supply amount of coins to the feeding unit 32 is adjusted by controlling the opening amount of the supply shutter 38 during the supply of coins to the feeding unit 32. When coins are additionally inserted into the insertion unit 37, a large amount of coins is supplied to the supply unit 32 at a time from the open portion of the supply shutter 38, and the supply unit 32 is likely to cause a supply failure. After the inlet shutter 18 is provided and the inlet shutter 18 is closed, the supply of coins to the feeding unit 32 is started to restrict additional coins from being inserted into the feeding unit 37. The occurrence of feeding failure can be prevented.

In addition, when the amount of coins to be inserted is larger than the capacity of the insertion unit 37, the coins cannot be inserted into the insertion unit 37 at a time, so that the coins are additionally inserted in a plurality of times.

In this case, the supply shutter 38 is closed and the slot shutter 18 is opened to allow additional coins to be inserted into the slot 37. Therefore, coins can be additionally input into the input unit 37 in parallel with the coin supply process in the supply unit 32. The operation of closing the supply shutter 38 and opening the input port shutter 18 is performed after the supply shutter 38 is fully opened or when an additional input instruction is input from the operation unit 23 or the like. After the coins are additionally thrown in, the slot shutter 18 is closed, and as described above, the supply shutter 38 is opened to supply the coins that have been additionally thrown into the feeding unit 32.

In addition, when coins are additionally inserted, the amount of coins stored in the temporary storage unit 35 for temporarily storing coins may be full. The amount of coins stored in the temporary storage unit 35 can be grasped by counting the count value by the identification unit 77. When full is detected, the depositing operation is temporarily stopped, the operator waits for confirmation of a storage or return command by the operator, and the storage operation or return operation described above is performed when the storage or return command is issued. When the storing operation is instructed, the depositing operation is automatically resumed after the storing operation is completed. When the returning operation is instructed, the return box 19 is removed and the deposit is performed by resetting. Restart operation automatically.

The capacity of coins that can be stored in the temporary storage unit 35 may be further increased.

In the above-described embodiment, the input port shutter 18 that slides by driving the input port shutter opening / closing mechanism 42 is used to open and close the input port 15. However, an open / close member that is manually opened and closed may be used. The opening / closing member may be slid with respect to the insertion port 15 or may be attached to and detached from the insertion port 15.

In the case of using this opening / closing member, a locking mechanism that locks the opening / closing member at the closing position of the insertion port 15 is used. Control to start supplying coins. As a result, during the supply of coins to the feeding unit 32, the coin is added to the input unit 37 even though the amount of coins supplied to the feeding unit 32 is adjusted by controlling the opening amount of the supply shutter 38. When inserted, a large amount of coins is supplied to the feeding unit 32 from the open part of the supply shutter 38 at a time, and the feeding unit 32 is likely to cause a feeding failure. It is possible to prevent the feeding failure by the feeding portion 32 by restricting the feeding.

The present invention is used for a coin processing machine such as a depositing machine, a depositing / dispensing machine or a coin wrapping machine.
