Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a denomination sorting 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 using the metal sensor 5, the coins passing on the conveyance path 3 are detected and counted according to their denominations.

The denomination to be counted is selected by switching the set position of the denomination cam 2 from the largest diameter coin (500 yen coin when passing through Japan) 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, a eject port 60 provided in the middle of the conveyance path 3 has a width of 500 yen coin C6°. The width is set to allow passage of only

As the rotary disk 1 rotates, the coins that have entered the conveyance path 3 due to centrifugal force are placed on the conveyance path 3 by pulleys 7 and 80.
It moves on the conveyance path 3 by 90 rotations of the feed belt stretched between them.

At this time, the 500 yen coin C3°. can pass through the conveyance path 3, but the 100 yen coin Cl11° and other coins fall down from the reject boat 6 and are stored in a reservoir (not shown).

500 yen coin C3° 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 boat 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 boat 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.

Further, in the case of the above-mentioned conventional example, large and small coins, etc. may intertwine on the conveyance path 3, causing jamming.

When this jam occurs, in the conventional example, it was necessary to remove the housing of the device and remove the jammed coins, etc. by hand. Moreover, even if you try to move the sorting course 4 to remove the stuck coins, etc., the denomination cam 2 gets in the way.
The width of the conveyance path 3 cannot be increased. Moreover, when trying to rotate the denomination cam 2, the corner of the denomination cam 2 gets into the sorting course 4, making it difficult to rotate.
If the denomination cam 2 is rotated forcibly, the corner of the denomination cam 2 may be crushed.

(Means for Solving the Problems) In order to solve the above 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 the width of the discharge port, and a width adjustment mechanism that adjusts the width of the conveyance path and the width of the discharge port, and a width adjustment mechanism that responds to a command that determines the type of coins to be sorted based on the diameters of a plurality of types of coins that are stored in advance. A means for controlling the width adjustment mechanism is provided so that the width of the conveyance path and the discharge port is a width for sorting the coins, etc. to be sorted, and further, a means is provided for controlling the width adjustment mechanism so that the width of the conveyance path and the discharge port is a width for sorting the coins, etc. The present invention is characterized in that upon detection, the conveyance of coins, etc. is stopped, and the width of the conveyance path is expanded.

(Function) The present invention uses the width adjustment mechanism and the control means for the width adjustment mechanism to adjust the width of the conveyance path and the discharge port to sort coins, etc. selected according to a command that determines the type of coins, etc. to be sorted. The width can be set automatically. This results in
Unlike the conventional example, there is no need to select the denomination by operating the denomination cam, and the operation becomes easier.

Further, in the present invention, when a coin or the like is jammed on the conveyance path, it is possible to automatically release the jam by detecting this and expanding the width of the conveyance path. can.

(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 screw 12 whose tip is fixed to the sorting course 4, and a lead nut 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.

Further, in this embodiment, a metal sensor 5' is provided to detect whether or not a coin is present on the rotary disk 1.

As shown in FIG. 2, the controller 20 is mainly configured with an arithmetic processing unit (hereinafter referred to as rcPU J) 21 such as a microcomputer, and receives a switch signal S from a manual selection switch 22 and an automatic selection switch 2.
3, a detection signal S from the home position sensor 18 input via the sensor buffer 24, and a detection signal S2 from the metal sensors 5 and 5'.
A switch signal S7 from the jamming release switch 29 is also input.

Further, the CPU 21 outputs a drive control signal D3 for the step motor 16, and this drive control signal D3 is
In the step motor drive circuit 28, the step motor 1
6 is converted into a pulse current signal S3 and output.

Furthermore, from the CPU 21, the count value of the coins being sorted,
Data D and total amount data D2 are output, and these data 01.0 are displayed on the count value display 27 and amount display 26.
The contents of 2 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.

3 and 4 are flowcharts showing the processing executed by the CPU 21, and the processing shown in FIG.
The process of sorting denominations, shown in FIG. 4, is a process of removing coins stuck on the transport path 3 (jamming release process).

First, the denomination sorting process shown in FIG. 3 will be explained.

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 4L42, in order to set the width of the conveying path 3 to a width approximately equal to the diameter of the coin of the specified denomination in accordance with the denomination specified by the manual selection switch 22, data is stored in the memory in advance. A pulse for reading out the data corresponding to the designated denomination from the stored width data of the conveyance path 3 corresponding to the diameter of each denomination, and obtaining the corresponding rotation angle of the step motor 16. The numerical data is obtained and output as a 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 coins counted from the counted value obtained in step 43 and the specified denomination is calculated, and this total amount and the counted value are displayed on the amount display 26 and the counted value display 27. do.

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 output this as the drive control signal D3. do.

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

After setting the width of the transport path 3, the rotary plate 1 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 C3°. Only the reject boat 6 passes through the conveyance path 3 without falling off, and is 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 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 step motor 16 is controlled to set the width of the conveyance path 3 to this width. .8 was rotated and 1 passed through the conveyance path 3.
Count the 0 yen coins Cl11.

Here, on the rotary disk 1 is the 50 yen coin C3°.

Through the sorting operation, coins that have fallen off the reject boat 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 coins with the smallest diameter (1 yen coins) is completed, the counted 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 processing in 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 boat 6 are automatically set to a width corresponding to the coins to be sorted.

Note that the processes performed in steps 35, 44, 52, etc. above are performed by detecting that the coin is no longer present on the rotary disk 1 based on the detection signal S of the other metal sensor 5'. is also possible.

Next, the jamming release process shown in FIG. 4 will be explained.

Step 61 is a process of determining whether or not the jamming release switch 29 has been operated. The jamming release switch 29 is for forcibly executing a jamming release operation, which will be described later, by a switch operation.

For example, when coins become jammed on the transport path 3 (jamming condition) and coins cannot be sorted, the metal sensor 5
′ does not work properly, so it may not be possible to detect this, or
Use this when you want to go just in case.

Furthermore, through the processes of steps 62 and 63, a process of automatically detecting the occurrence of jammed coins, etc. is performed. That is, in step 62, it is determined whether or not there are still coins on the rotary disk 1 based on whether the output of the metal sensor 5' is ON, and in step 63, it is determined whether the output of the metal sensor 5 is OFF or not. Accordingly, it is determined whether or not there are any coins on the conveyance path 3.

As a result, even though there are coins on the turntable 1,
If the coin is not transported to the transport path 3, the coin is not transported to the transport path 3.
This means that there is a coin jam on top of the coin.

When the above-mentioned jamming release switch 29 is turned on, and by the processing of steps 62 and 63,
When a jam of coins or the like is detected, steps 64-
67 jamming release processing is executed.

Step 64 is a drive control signal D for the step motor 16.
3 and moves the sorting course 4 upward in FIG. 1 to expand the width of the conveyance path 3.

In step 65, based on the output signal SI of the home position sensor 18, it is determined whether the sorting course 4 has been extended to the home position.

Therefore, through the processing in steps 64 and 65, the sorting course 4 is expanded to the home position. Here, the rotation of the turntable 1 continues, but the rotation of the boot I77.8 is stopped.

As a result, the coins stuck on the conveyance path 3 are freed by the expansion of the sorting course 4 and removed by the rotation of the rotary disk 1. Furthermore, since the pulleys 7.8 are stopped, no coins will enter onto the conveyance path 3 during this time.

As described above, after the sorting course 4 is moved to the home position, after a certain period of time, the processes of steps 66 and 67 are executed, and the sorting course 4 is moved to the position immediately before the expanding operation of the sorting course 4 is performed. Perform the action to return.

When this operation is completed, the stopped pulley 7
．． 8 and automatically restarts the denomination sorting operation.

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.

Furthermore, if a coin or the like is clogged at the entrance of the conveyance path, it is more effective to reverse the apparatus and clear the jam.

(Effects of the Invention) As explained in detail above, the present invention provides a width adjustment mechanism for adjusting the width of the conveyance path and discharge port for sorting coins, etc., and a control circuit for this width adjustment mechanism. By this,
The width of the conveyance path and the discharge port can be automatically set to a width for sorting coins, etc. selected by a command that determines the type of coins, etc. to be sorted. This eliminates the need to select the denomination by operating the denomination cam as in the conventional example, and the operation becomes easier.

Further, in the present invention, when a coin or the like is jammed on the conveyance path, it is possible to automatically release the jam by detecting this and expanding the width of the conveyance path. can.
