Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a coin handling machine used in automatic deposit/withdrawal devices installed in financial institutions.

(Prior Art) A coin processing machine includes a hopper that is opened and closed by a lid with a lock, a means for identifying and counting inserted coins as proper coins and improper coins, and a means for distinguishing and counting inserted coins into proper coins and improper coins. Conventionally, there is a belt conveyor for returning and conveying invalid coins to a hopper (see Japanese Patent Laid-Open No. 60-33691). As a result, invalid coins are returned to the hopper, and even valid coins are returned to the hopper if the depositor does not approve the coin acceptance.

(Problem to be solved by the invention) In the case of the above-mentioned coin processing machine, if the inserted coins become jammed inside the machine due to a problem, the number of coins inserted and the number returned will be different. It ends up. In such cases, with conventional coin processing machines, the depositor could take out the returned coins from the hopper even if the number of coins inserted and the number of returned coins were different. Trouble sometimes occurred with the person installing the treatment machine.

Therefore, by counting the number of returned coins, the present invention prevents the above-mentioned trouble by preventing the depositor from taking out coins if the number of coins inserted and the number of returned coins do not match. It is an object of the present invention to provide a coin processing machine that can reduce malfunctions by performing counting reliably.

(Means for Solving the Problems) The features of the present invention in order to solve the problems of the prior art are that the hopper 5 is opened and closed by a locking lid 4, and that the coins inserted into the hopper are converted into appropriate coins. a belt conveyor 37 for returning and conveying the identified and counted valid coins and invalid coins to the hopper 5, respectively;
In a coin processing machine equipped with If the numbers do not match, the lock of the lid 4 is determined to be impossible to release, and if the number of properly inserted coins and the number of returned properly coins do not match, the lock of the lid 4 is determined to be impossible to release. The means for counting the coins to be returned includes holes 43 opened at regular intervals in the coin conveying section of the belt conveyor 37, and a counting sensor that transmits and receives signals passing through the holes 43. The number of coins is counted by blocking the signal passing through the coins by the returned coins.

(Operation) The coins put into the hopper 5 are distinguished as proper coins and improper coins and are counted. When the identified and counted correct coins and incorrect coins are returned to the hopper 5 by the belt conveyor 37,
Each is counted by a counting means. If the number of invalid coins thrown in and the number of invalid coins returned do not match, the lid 4 of the hopper 5 is not unlocked, and the depositor cannot take out the coins. Furthermore, even if the number of proper coins inserted does not match the number of proper coins returned, the lid 4 of the hopper 5 is not unlocked, and the depositor cannot take out the coins.

Coins are returned to hopper 5 on belt conveyor 3
7. Therefore, if the coin is not returned to the hopper 5, the signal passing through the hole 43 of the coin conveying section of the belt conveyor 37 will not be blocked by the coin. Further, when coins are returned to the hopper 5, the signal passing through the hole 43 is blocked by the coins, and the number of returned coins is counted.

is supplied onto the rotating disk 21 of. Note that 50 is a wall that separates the customer floor side from the bank staff room side.

Next, the operation of the coin processing machine having the above configuration will be explained.

First, when depositing money, the lid 4 of the deposit/withdrawal device 3 is opened and coins are dropped into the hopper 5. Next, close the lid 4 and press the operation start button. By this operation, the lid body 4 is locked, a take-in command is issued, the shutter 6 at the bottom of the hopper 5 opens, and the coins in the hopper 5 fall onto the rotating disk 9 below. The coins on the rotating disk 9 are fed one by one onto the identification path 10 of the coin identification device 8 by the centrifugal force of the rotating disk 9.

The coins sent out to the identification path 10 are conveyed rearward by a conveyor belt. At this time, counterfeit coins and the like having a diameter smaller than genuine coins are discharged from the small-diameter coin discharging section 13 and stored in the small-diameter pot 18 via the chute 17.

The coins that have passed through the small-diameter coin ejecting section 13 without being ejected are counted by the counting sensor 14 as the total number A.
is counted, and furthermore, the number B of proper coin denominations is counted by the next identification sensor 15, and the number C of improper coins is counted. The counterfeit coins detected by this identification sensor 15
from there through the chute 19 to the connecting chute 39. The invalid coins ascend through the vertical conveyor 37 and are discharged from the refund port 7 into the hopper 5 of the deposit/withdrawal device 3. At this time, vertical conveyor 3
A coin counting sensor 40 provided at 7 counts the number D of ejected coins. At this time, A=B+
A check of D or C=D is performed by the control device, and if A>B+D or C>D, a differential abnormality signal is issued and the lock of the lid 4 is not released. A=B
In the case of +D or C=D, the lid 4 is unlocked and the returned money in the hopper 5 can be collected.

The valid coins that have passed through the invalid coin discharging section 16 without being discharged are stored on the rotating disk 21 of the temporary storage device 20. At this time, the number of appropriate coins counted is displayed on a display panel (not shown), so the depositor confirms the displayed amount and then operates a button to approve or disapprove the deposit.

In the case of rejection of acceptance, when the rejection button is operated, the cover body 24 opens and the coins on the rotating disk 21 are sent out one by one. At this time, the path of the branching section 27 is switched to the coin discharge side, and the coins sent out pass through the discharge chute 29 and are transferred to the horizontal conveyor 3 below.
6 falls on top. The horizontal conveyor 36 is indicated by the arrow b in the diagram.
The fallen coin moves forward and is transferred to the vertical conveyor 37 via the connecting chute 39.
After the number E is counted by the counting sensor 40, the number E is transferred from the refund opening 7 to the hopper 5.
Expelled inward.

At this time, if A=D+E or B=E is checked and the above formula is established, the lid 4 is unlocked as a normal refund and the returned coins in the hopper 5 can be taken out. If the above formula does not hold true, the abnormality alarm device is activated as a differential error and the lid 4 is not unlocked.

Next, in the case of acceptance, the path of the branching section 27 is switched to the sorting section side, and the coins sent out from the temporary holding device 20 are transferred to the sorting section 28. Since the sorting section 28 has a sorting port 30 from a small diameter to a large diameter, the denominations fall downward from the sorting port 30 and are sorted for each denomination. The sorted coins are stored by denomination in a storage cylinder 32 of a coin storage device 31 arranged below. When the storage tube 32 becomes full, the overflow device 33 switches the path, and only the one that is full changes its falling path to the safe side. Due to this path switching, full coins are directly collected into the safe device 38 via the chute 34.

Further, when all the storage cylinders 32 are full, the branching section 27 is switched to the discharge side, and the coins sent out from the temporary holding device 20 fall onto the horizontal conveyor 36 via the discharge chute 29. At this time, the horizontal conveyor 36 rotates in the direction of arrow a and collects the coins into the safe device 38.

Next, to explain the dispensing operation, by operating the dispensing button of a predetermined amount, the coin dispensing device of the storage device 31 is activated, and the coin dispensing device of the storage device 31 is activated.
2 to a predetermined number F of coins are discharged onto the horizontal conveyor 36. The horizontal conveyor 36 rotates in the direction of arrow b to send the coins forward, and the vertical conveyor 37 transports the coins upward, and the counting sensor 40 counts the number G of coins and discharges them into the hopper 5. and,
If F=G, the lid 4 is unlocked and can be taken out, and if F>G, the differential failure device is activated and the lid 4 is not unlocked.

In addition, 51 is a forgotten pot, and hopper 5
This is a pot for collecting coins when you forget to take out or return them, and a damper 52 installed in the middle of the ejection chute 29 switches the path and stores the coins in the forgotten pot 51. It is said to be recoverable.

Further, the replenishing device 47 is activated to replenish coins when there are no more coins in the storage cylinder 32. This replenishment may be performed either by automatically detecting a decrease in coins and replenishing the coins, or by manually operating a button.

(Effect of the invention) According to the coin processing machine of the invention, if the number of coins inserted and the number of returned coins do not match, the depositor cannot take out the coins because the hopper lid is not unlocked. Even if a depositor misunderstands the number of coins deposited, no trouble will occur between the depositor and the processor installer.

Further, by configuring the returned coin counting means using a belt conveyor that returns coins, the number of returned coins can be reliably counted.
