Abstract

PROBLEM TO BE SOLVED: To provide a coin sorting device which does not decrease in reception rate even when 100-yen coins are successively thrown in as a coin sorting device with a temporary holding function. SOLUTION: A gate G1 which discriminates 100-yen and 500-yen coins and 10-yen and 50-yen coins is presented on the downstream side of a coin discrimination part 3 which discriminates the kind and genuineness of a thrown-in coin and a gate SUB0 which distributes 100-yen coins to an auxiliary change tube (SUB) is provided in a path that the 10-yen and 50-yen coins discriminated by the gate G1 pass through. The gate SUB0 is driven by an escrow solenoid which drives escrow projection parts 6 and 7 of a temporary holding part which temporarily hold the 100-yen cons and send them out, one by one. When the device is so set that no 100-yen coins are temporarily held, coins are sent directly to the auxiliary change tube (SUB) through the gates G1 and SUB0, so the reception rate does not decrease even when the coins are successively thrown in.

Here, 100 yen / 500 is temporarily held
The passage structure of the yen coin will be described. Since the passage structure of the 500-yen coin has substantially the same structure as the passage structure of the 100-yen coin, the passage structure of the 100-yen coin will be described here.

FIG. 5 shows a conventional escrow type coin discriminating apparatus 1
It is a schematic side view which shows the flow of a 00-yen coin. 5, the same elements as those shown in FIG. 4 are designated by the same reference numerals.

A coin 11 inserted from a coin receiving opening 101
0, the type and authenticity (coin or counterfeit) of the coin 110 is discriminated through the coin discriminating unit 102, and according to the discrimination result, the gate G0 sorts out the coins / counterfeit coins. In that case, you will be guided to the passage leading to the return port. In the case of a true coin, it is guided to the gate G2L, where 5
00 yen coins and 100 yen coins are sorted.
On the downstream side of the gate G2L, there is a temporary holding portion for 100-yen coins, and the escrow protrusions 105 and 106 are the levers 1.
An escrow solenoid 112 can be used to alternately enter and retract into the passage. Gates G2F and G3L are provided on the downstream side of the temporary holding unit so that the 100-yen coins released from the temporary holding unit are guided to the safe, the inspection tube, and the return port.

FIG. 6 is a diagram showing a standby state of the temporary holding section, and FIG. 7 is a diagram showing a coin processing state of the temporary holding section. In the standby state of the temporary holding section, the escrow solenoid 112 is in the off state.
Is retracted from the 100-yen passage 103, and the downstream escrow projection 106 projects into the 100-yen passage 103. As a result, in the 100-yen passage 103, the 100-yen passage 103 is blocked by the escrow protrusion portion 106, and the coin 110 a that has fallen into the 100-yen passage 103.
Are blocked by the escrow protrusion 106 and are temporarily held there.

The escrow solenoid 112 is turned on in the coin processing state of the temporary holding section. Then, the escrow solenoid 112 lifts one end of the lever 111 to cause the upstream escrow protrusion 105 to project into the 100-yen passage 103 and retract the downstream escrow protrusion 106 from the 100-yen passage 103. As a result, the temporarily held coin 110a is sent out, is guided to the sorting destination determined by the operation of the gates G2F and G3L, and the coin 110b that has dropped next is ejected to the escrow protrusion portion 1.
Take 05. When the escrow solenoid 112 is turned off again, it returns to the standby state and the escrow protrusion 1
The coin 110b, which was received at 05, is received at the escrow projection portion 106 below the coin 110b and temporarily held.

FIG. 8 is a diagram showing a state in which coins are temporarily held by the escrow type coin discriminating apparatus. The 100-yen and 500-yen coins that have passed through the gates G0 and G1 from the coin identifying unit 102 are sorted by the gate G2L, and the 100-yen coin is 1
500 yen coins are sent to the 00 yen passage 103 and the 500 yen passage 10
Each is led to 4. In the temporary holding section, the introduced coins are temporarily stored, and the stored escrow solenoid is turned off, turned on, and turned off. Will be stored.

FIG. 9 is a flow chart showing the flow of coin allocating operation of the conventional escrow type coin discriminating apparatus, and FIG. 10 is an operation matrix of the allocating solenoid. First, the type and authenticity (coin / counterfeit) of the inserted coin are discriminated by the coin discriminating unit 102. Gate G0
Performs the sorting operation based on the discrimination by the coin discriminating unit 102, and the fake coins are sorted to the return passage and the true coins are sorted to the gate G1 (step S1). At the gate G1, when the specie is 10 yen / 50 yen, the operation is turned on and 100 yen / 5
In the case of ¥ 00, the operation remains off (step S
2). In the case of 10 yen / 50 yen, the coin is the gate G2R
In the gate G2R, the ON operation is performed when the money is collected in the safe, and the OFF operation is otherwise performed and the operation is distributed to the gate G3R (step S3). Gate G
In 3R, if it is 10 yen, it remains off operation,
The yen coin is led to the change tube for 10 yen, and when it is 50 yen, it is turned on and the 50 yen coin is led to the change tube for 50 yen (step S4).

On the other hand, 100 distributed by the gate G1
Yen / 500 yen is distributed to the gate G2L, and when the distributed coin is 100 yen, the gate G2L operates on, and when it is 500 yen, it remains off (step S5). When the gate G2L turns on,
Guide the 100-yen coin to the 100-yen temporary holding section. 100
In the yen temporary holding section, the escrow solenoid is turned off-on-
The 100-yen coins that are turned off and temporarily held are sent out one by one (step S6). The sent 100-yen coin is guided to the gate G3L. When returning the 100-yen coin, the gate G3L is turned on and distributed to the return port, and when the money is collected or stored, the gate G3L remains in the off operation and is distributed to the gate G2F (step S).
7). In the gate G2F, the 100-yen coin is led to the change tube for 100-yen while being kept in the off-state when it is stored, and is turned on to collect the 100-yen-coin to the safe (step S8).

If the gate G2L remains off,
Guide the 500 yen coin to the 500 yen temporary holding section. In the 500-yen temporary holding section, the escrow solenoid is turned off-on-off operation to send out the temporarily held 500-yen coins one by one (step S9). The sent 500-yen coin is guided to the gate G3L. Gate G3L is 5
When the 00 yen coin is returned, the ON operation is performed and the coin is distributed to the return port. When the coin is collected or stored, the OFF operation is still performed and the coin is distributed to the gate G2F (step S10). In the gate G2F, when the storage is performed, the off operation is still performed, and
The 00-yen coin is led to the change-tube for 500-yen, and when it is collected, it is turned on to lead the 500-yen coin to the safe (step S11).

[0014]

However, in the conventional escrow type coin discriminating apparatus, the method of temporarily holding 100-yen coins is as shown in FIG. Therefore, there was a limit to the number of sheets to be held. Therefore, in the case of inserting more coins than the number of coins to be reserved, it is possible to receive the next coin after carrying out a process of distributing the first reserved coin to a change tube or a safe. Therefore, while the coins are being processed, there is a problem that the acceptance rate of the coins is lowered when the coins are forbidden and the coins are continuously inserted.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a coin discriminating apparatus in which the acceptance rate does not decrease even when 100-yen coins are continuously inserted.

[0016]

In the present invention, in order to solve the above problems, in a coin identifying device for identifying and allocating the type of inserted coin, the coin identifying means for identifying the type of coin is identified. Sorting means for sorting coins into corresponding change tubes based on the identification result,
A temporary holding means for temporarily holding the coins provided on the route of the sorted coins of a specific type, and a specific denomination sorting unit for allocating the coins of the specific type to an auxiliary change tube, A coin discriminating device is provided.

According to such a coin discriminating apparatus, the specific denomination sorting means can sort the specific type of coins into the auxiliary change tube without distributing the specific type of coins to the temporary holding means. I made it up. Thus, by setting that the coins of a specific type are not temporarily held by the temporary holding means, even if the coins of a specific type are continuously inserted, the specific denomination sorting device continuously performs the sorting operation and the auxiliary change tube. Since it is distributed to, the acceptance rate will not decrease.

[0018]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings, taking a case where the embodiment is applied to an escrow type coin identification device as an example.

FIG. 1 is a front view showing a schematic structure of an escrow type coin discriminating apparatus to which the present invention is applied. An escrow type coin discriminating apparatus 1 according to the present invention has a coin receiving port 2 for receiving coins inserted in the upper part of the drawing, and a coin discriminating unit 3 for determining the type and authenticity of coins inserted in the lower part thereof. There is. In the lower part of the coin discriminating unit 3, a gate G0 is arranged to accept the identified coin if it is a true coin, and to direct it to the return slot if it is a false coin, and 100 or 500 yen or 10 yen for the accepted coin. It is equipped with a gate G1 that sorts by 50 yen. The gate G1 also performs the same operation when storing 100-yen coins in an auxiliary change tube (SUB) as when the coins are 10-yen and 50-yen. At the lower part of the gate G1, a gate G2R for allocating coins distributed by the gate G1 as 10 yen or 50 yen to the cashbox and a gate for distributing uncollected coins to a 10-yen tube or a 50-yen tube It is provided with a G3R and a gate SUB0 for allocating 100-yen coins allocated for storage to an auxiliary change tube (SUB).

Further, below the gate G1, there is provided a gate G2L for distributing coins distributed by the gate G1 as 100 yen or 500 yen to the 100-yen passage 4 or the 500-yen passage 5. The 100-yen passage 4 is provided with escrow protrusions 6 and 7 which can be moved forward and backward with respect to the passage space, and the 500-yen passage 5 is provided with escrow protrusions 8 and 9 which can be moved forward and backward with respect to the passage space. And each of them constitutes a temporary holding section. These 10
At the lower part of the 0-yen passage 4 and the 500-yen passage 5, coins temporarily held are returned to the return port, safe or 100-yen tube / 5.
It is equipped with gates G2F and G3L that distribute to 00 yen tubes. Then, in the lower part of the gates G3R, G2F, G3L, a 10-yen tube, a 50-yen tube, a 100-yen tube, a 500-yen tube and an auxiliary change tube (S
The change tube part 10 made of UB) is arranged.

The passage structure of the temporarily held 100 yen / 500 yen coin has the same structure as the passage structure for the 100 yen coin of the conventional escrow type coin discriminating apparatus shown in FIG. However, the escrow solenoid that sends out the temporarily held 100-yen coins is linked to the gate SUB0. SUB). This is because if the 100-yen coin is not temporarily held, the 100-yen temporary holding unit does not send out the 100-yen coin. Therefore, the escrow solenoid that sends out the 100-yen coin is also used as the drive source of the gate SUB0. There is

Next, the operation of the escrow type coin discriminating apparatus 1 having the above configuration will be described. FIG. 2 is a flow chart showing the flow of the coin allocating operation of the escrow type coin discriminating apparatus according to the present invention, and FIG. 3 is a diagram showing an operation matrix of the allocating solenoid of the escrow type coin discriminating apparatus according to the present invention.

First, the coin discriminating unit 3 discriminates the type and authenticity (coin / counterfeit) of the inserted coin. The gate G0, based on the discrimination result by the coin discriminating unit 3,
In the case of a fake coin, the off operation remains, and in the case of a true coin, the on operation is performed (step S21). As a result, the false coins are distributed to the return passage and the true coins are distributed to the gate G1. At the gate G1, when the sorted true coins are 10 yen / 50 yen, the ON operation is performed, and when the allocated true coins are 100 yen / 500 yen, the OFF operation remains (step S22). When the 100-yen coin is not temporarily held, the gate G1 is turned on.

In the case of 10 yen / 50 yen and 100 yen without temporary holding, the coins are distributed to the gate G2R, and at the gate G2R, the ON operation is performed when the money is collected in the safe, and the other OFF operation is performed. As it is, gate SUB0
(Step S23). Gate SUB0
Then, in the case of 100 yen without a temporary hold, the ON operation is performed and the 100 yen coins are distributed to the auxiliary change tube (SUB).
Yen or 50-yen coins are distributed to the gate G3R (step S24). In the case of gate G3R, if it is 10 yen, the 10 yen coin is distributed to the change tube for 10 yen while it remains off, and if it is 50 yen, it is turned on and the 50 yen coin is changed for 50 yen. Sort into tubes (step S25).

On the other hand, 100 distributed by the gate G1
JPY / 500 JPY (5 if set to 100 JPY without temporary hold)
(00 yen only) is distributed to the gate G2L, and when the distributed coin is 100 yen, the gate G2L turns on, and when it is 500 yen, it remains off (step S26). When the gate G2L is turned on, the 100-yen coin is guided to the 100-yen temporary holding section. 1
In the 00-yen temporary holding section, the escrow solenoid is turned off-on-off to send out the temporarily held 100-yen coins one by one (step S27). 1 sent out
The 00 yen coin is guided to the gate G3L. Gate G3L
When returning the 100-yen coin, it is turned on and sorted to the return port, and when it is collected or stored, it is turned off and sorted to the gate G2F (step S28). In the gate G2F, the 100-yen coin is distributed to the change tube for 100-yen while being stored in the off operation when it is stored, and the on-operation is distributed to the 100-yen coin when collecting money (step S29).

If the gate G2L remains off,
Guide the 500 yen coin to the 500 yen temporary holding section. In the 500-yen temporary holding unit, the escrow solenoid is turned off-on-off operation to send out the temporarily held 500-yen coins one by one (step S30). The sent 500-yen coin is guided to the gate G3L. When returning the 500-yen coin, the gate G3L turns on and distributes it to the return port, and when collecting or storing the coin, it keeps off and distributes it to the gate G2F (step S31). In the gate G2F, when the storage is performed, the off operation is still performed, and
The 00-yen coin is distributed to the change-yen tube for 500-yen, and when collecting, the ON operation is performed to distribute the 500-yen coin to the safe (step S32).

As described above, the escrow type coin discriminating apparatus 1 according to the present invention leaves the mechanism for temporarily holding 100-yen and 500-yen coins in the passage portion as before, and further inserts 100-yen coins.
With the structure that the yen coins are not guided to the normal 100-yen escrow passage and are distributed to the supplementary change tube (SUB) by the newly added gate SUB0, if 100 yen without temporary holding is set, 100-yen coins will be Auxiliary change tube (SUB) without being distributed to the temporary holding section
Will be assigned to. As a result, it is possible to shorten the receiving interval in the continuous insertion of 100-yen coins. In the past, the receiving interval in continuous insertion was about 1 second per coin, but in the present invention, since there is no temporary holding and sending operation by the escrow solenoid, about 0.5 seconds per coin. Becomes

The structure for allocating to the supplementary change tube (SUB) can be used as a means for allocating specific medals, etc. without being particular about 100-yen coins.

[0029]

As described above, according to the present invention, 10
Gate SUB that distributes 0-yen coins to auxiliary change tubes
It is configured to include 0. As a result, even if 100-yen coins are continuously inserted, the gate SUB0 continuously distributes the coins to the auxiliary change tubes, so that the acceptance rate does not decrease.

By using the gate for allocating 100-yen coins to the auxiliary change tube as the drive source of the escrow solenoid of the temporary holding section, a new drive source for driving the gate is not required and the cost increase can be suppressed. .
