Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a denomination identification device that can be used in coin counters, medal counters, and the like.

(Prior Art) Conventionally, coin counters have been generally used as devices for counting the number of coins in sales proceeds by denomination in stores, financial industries, and the like.

As shown in Fig. 4, in this conventional coin counter, a plurality of coins of different denominations are placed on a rotary disk (money storage section) 1, and a denomination cam 2 is manually operated. By sequentially rotating the coins, coins passing on the conveyance path 3 are detected and counted by medal sensor 5 according to denomination.

The denominations to be counted are selected by changing the setting position of the denomination cam 2 from the largest diameter coin (500 yen coin in Japanese currency) to the positions corresponding to the smaller diameter coins.

That is, initially, the denomination cam 2 is set at a position for sorting 500 yen coins. As a result, return spring 1
The sorting course 4, which is elastically supported at 0, moves, and the width of the conveying path 3 is C3 degrees for a 500 yen coin. is set to the diameter of Along with this, the width of the eject port (discharge port) 6 provided in the middle of the conveyance path 3 is C3° for a 500 yen coin. The width is set to allow passage of only

As the rotary disk 1 rotates, the coins that enter the conveyance path 3 due to centrifugal force are moved onto the conveyance path 3 by 90 rotations of a feed belt stretched between pulleys 7 and 8. will be moved.

At this time, the 500 yen coin C3°. can pass through the conveyance path 3, but the 100 yen coin Cl00 and other coins fall down from the reject port 6 and are stored in a reservoir (not shown).

500 yen coin C5° passed through conveyance path 3. After being detected by the metal sensor 5, it is stored in another reservoir.

In this way, when there are no more coins on the rotary disk 1, the number of 500 yen coins will be displayed on the display (illustrated path).

Next, the denomination cam 2 is manually switched and set to the sorting position for the second largest diameter coin, that is, the 10 yen coin.

On top of the rotary disk 1 is a coin dropped from the reject port 6, that is, a 500 yen coin C3°.

Place the removed coin.

This time, the width of the transport path 3 is equal to the diameter of the 10 yen coin, and only 10 yen coins pass through the transport path 3 and are counted. Other coins are dropped from the reject port 6.

After that, by manually changing the denomination cam 2, 100 yen coins,
Counting is performed for each denomination in the order of 5 yen coins, 50 yen coins, and 1 yen coins.

(Problems to be Solved by the Invention) However, in the conventional coin counter described above, the denominations are sorted by the denomination cam 2, which is time-consuming and takes a long time. Ta.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention provides a denomination sorting device for sorting coins, etc. by a conveyance path having an ejection port, as in the conventional example. A width adjustment mechanism that adjusts the width of the conveyance path and a width of the discharge port; and a width adjustment mechanism that controls the width of the conveyance path and the width of the discharge port based on pre-stored diameters of multiple types of coins, etc. A width adjustment mechanism control circuit is provided to automatically switch and set the width.

The present invention is further characterized in that the width adjustment mechanism control circuit includes initial setting means and sorting width switching means.

The initial setting means, in response to a predetermined initial setting command,
The width of the conveyance path is set to be approximately equal to the diameter of the largest diameter of the stored coins, etc., and the width of the discharge port is set to be approximately equal to the diameter of the largest diameter coin, etc. among the stored diameters of the coins, etc. etc., set the width to make it fall off.

The sorting width switching means changes the width of the conveyance path to the next largest diameter every time there are no coins, etc. in the money storage section that stores coins, etc. to be sent to the conveyance path after the width is set by the initial setting means. The width is set to be approximately equal to the diameter of the coin, etc., and the width of the discharge port is changed to a width that allows coins, etc. other than the coin, etc. to fall out.

(Function) The present invention does not require the manual setting operation of the denomination cam as in the conventional example, and the width of the conveying path and the width of the discharge port are automatically adjusted by the width adjustment mechanism and the width adjustment mechanism control circuit. It is possible to switch settings automatically, and it is possible to sort out multiple types of coins, etc. quickly and without much effort.

(Embodiment) FIG. 1 shows the configuration of an embodiment of the present invention. In this figure, the same components as those of the conventional example shown in FIG.

This embodiment eliminates the denomination cam 2 and return spring 10 in the conventional example shown in FIG. ) 11 is provided.

The screw feeding device 11 consists of a lead screw 12 whose tip is fixed to the sorting course 4 and a lead napft 14 that is screwed onto the lead screw 12. It has become. Further, the lead napft 14 is supported by a fixed base 13, and when the lead napft 14 rotates with the rotation of the output gear 15, the lead screw 12 is displaced in the vertical direction in the figure, displacing the sorting course 4.

The rotation angle of the step motor 16 is controlled by a controller (width adjustment mechanism control circuit) 20.

As shown in FIG. 2, the controller 20 is mainly composed of an arithmetic processing unit (rCPU J) 21 such as a microcomputer, and receives switch signals from a manual selection switch 22 and an automatic selection switch 2.
3, a detection signal SI from the home position sensor 18 input via the sensor buffer 24, and a detection signal S2 from the metal sensor 5 are input.

Further, the CPU 21 outputs a drive control signal D3 for the step motor 16, and this drive control signal D3 is converted into a pulse current signal S3 given to the step motor 16 in the step motor drive circuit 28 and output.

Furthermore, the CPU 21 outputs the count value data D of the coins being sorted, the total amount data D2, and the data of the specified denomination, and displays the count value display 27 and the amount display 26.
, the contents of these data D, D, and the designated denomination are displayed.

The home position sensor 18 is connected to the screw feeding device 11.
This is to detect whether or not the sorting course 4 is at its original position (home position) based on whether or not the sensor plate 17 attached to the open end of the lead screw 12 blocks the light.

FIG. 3 is a flowchart showing the processing executed by the CPU 21.

In step 31, it is determined whether or not the denomination to be sorted has been selected by operating the manual selection switch 22. The manual selection switch 22 is a switch for inputting a command to that effect when the operator desires to sort a specific denomination (for example, when wanting to sort only 100 yen coins).

When the manual selection switch 22 is operated, steps 41 to 44 and 53 are executed to select the designated denomination, and display the coin count and total amount.

In step 41.42, manual selection switch 22
The width of the conveyance path 3 is set according to the denomination specified by
In order to set the width to be approximately equal to the diameter of the coin of the specified denomination, the width of the conveyance path 3 corresponding to the diameter of each denomination is stored in advance in the memory. The data corresponding to the seed is read out, and the pulse number data for obtaining the corresponding rotation angle of the step motor 16 is determined and outputted as the drive control signal D3.

When the width of the transport path 3 has been set, the number of coins detected by the metal sensor 5 is counted in step 43.

In step 44, the metal sensor 5
Since no coins are detected, it is determined that no coins are present on the rotary disk 1, and the counting process is terminated.

Then, in step 53, the total amount of the counted coins is calculated from the counted value in step 43 and the designated denomination, and this total amount, the counted value, and the designated denomination are calculated on the amount display 26. It is displayed on the numerical display 27.

Next, a case where the automatic selection switch 23 is turned on will be described.

When the automatic selection switch 23 is turned on, step 3
The determination in step 2 is YES, and the process in step 33 is performed.

In this step 33, among the data on the width of the conveyance path 3 corresponding to the diameter of the coin for each denomination stored in the memory,
Read the data corresponding to the largest diameter coin (500 yen coin in the case of Japan), find the pulse number data to obtain the corresponding rotation angle of the step motor 16, and use this as the drive control signal D command. Output as .

As a result, the width of the conveyance path 3 is set to be approximately equal to the diameter of a 500 yen coin, and the width of the reject port 6 is set to a width that allows coins other than the 500 yen coin to fall out.

After setting the width of the transport path 3, the rotary plate l and pulley 7
．． 8 starts to rotate, and a plurality of coins of a plurality of different denominations on the rotary disk 1 are sequentially fed into the conveyance path 3.

And 500 yen coin C2°. Only the metal particles pass through the conveyance path 3 without falling off from the reject port 6, and are detected by the metal sensor 5. 5 detected by this metal sensor 5
00 yen coin C3°. is counted in step 34.

The process of step 35 is the same process as step 44, and is a process of detecting that there are no more coins on the rotary disk 1 and stopping the counting operation.

If the determination in step 35 is YES, then step 3
6 is processed, and the next largest diameter coin (10 yen coin)
The sorting process is performed in substantially the same manner as the processes in steps 33 to 35 described above.

That is, data on the width of the conveyance path 3 corresponding to a 10 yen coin is obtained from the memory, the rotation of the step motor 16 is controlled so as to set the width of the conveyance path 3 to this width, and then the rotation of the rotary disk 1 and the pulley is controlled. 7.8 is rotated to count the 10 yen coins C3° that have passed through the conveyance path 3.

Here, on the rotary disk 1 is the 500 yen coin C3°.

As a result of the sorting operation, the coins that have fallen out of the reject port 6 and are accommodated in a reservoir (not shown) are placed. That is, there are no 500 yen coins.

In this way, when the counting of 10 yen coins is completed, the coins with the next largest diameter (100 yen coins) are sorted in the same way.
yen, then 1 yen) sorting process is performed.

Then, when the counting of the smallest diameter coins (1 yen coins) is completed (steps 51 and 52), the count value for each denomination and the total amount (the total amount of all coins and the total amount for each denomination) are calculated by the process of step 53. total amount).

In this way, in this embodiment, coins with the next largest diameter are sorted sequentially starting from the largest diameter coin, and at this time, the sorting course 4
is automatically displaced, and the widths of the transport path 3 and the reject port 6 are automatically set to a width corresponding to the coins to be sorted.

In the above embodiment, an example was shown in which Japanese currency is sorted, but it goes without saying that the present invention can also be applied to a device that sorts foreign coins or medals into denominations or types.

(Effects of the Invention) As described above in detail, the present invention includes a width adjustment mechanism for adjusting the width of the conveyance path and the discharge port for sorting coins, etc., and a control circuit for this width adjustment mechanism. By automatically switching and setting the widths of the conveyance path and the discharge port so that coins with the next largest diameter are sorted sequentially from the largest diameter coins, etc., the above-mentioned conventional example can be improved. There is no need to manually set the denomination cam, and multiple types of coins, etc. can be quickly sorted with a simple operation.
