Description

[Detailed explanation of the invention] [Purpose of the invention] (Field of industrial application) The invention supplies coins of a mixed denomination onto a rotating disk, and the centrifugal force caused by the rotation of the rotating disk causes the coins to be separated from their periphery. The coins are transported to a coin sorting passageway having coin sorting slots arranged in order from small diameter coins to large diameter coins. Foreign coins, counterfeit coins, worn coins, deformed coins, etc. are excluded from classification, and coins determined by machine design (hereinafter referred to as foreign coins) can be automatically excluded. This invention relates to a coin sorting machine that can be used during continuous operation.

(Prior art) As a conventional coin processing machine of this type, for example,
There is a device as shown in the -126291 publication. In this device, coins supplied onto a rotating disk are moved to the periphery by centrifugal force due to the rotation of the rotating disk, and are sent one by one into a coin passage extending from the periphery to the outside of the rotating disk. The coins are sorted by denomination and the number of coins is counted by the coin sorting grooves arranged in the order of small diameter coins to large diameter coins in the coin passage.

On the other hand, apart from this, there is a device as described in Japanese Unexamined Patent Publication No. 14087/1987. This device sends the coins supplied to the hopper to the sorting section via an inclined disk, and the discrimination section upstream of the sorting section discriminates the coins.As a result of the discrimination, coins that are determined to be unprocessable are discriminated as different types of coins. It is stopped immediately after the separation section to prevent it from being transported to the subsequent sorting section. Further, subsequent coins sent out by the inclined disk are collected into the hopper by the protruding action of a collection piece provided immediately before the discrimination section. In this device, the coins roll through the inclined sorting passageway due to their own weight.

(Problem to be solved by the invention) By the way, in the case of the device described in the former gazette, even if foreign coins (unprocessable coins such as foreign coins and counterfeit coins) are mixed in the supplied coins, However, the coins are sent to the coin passageway and sent to the coin sorting slot for sorting out coins of any denomination, and cannot be rejected as coins of a different type.

On the other hand, in the case of the device described in the latter publication, when a different type of coin passes through the discrimination section, the coin is stopped and is not sent to the subsequent sorting passage.

However, this device does not have a means for transporting coins, and the coins move only by rolling due to their own weight on an inclined path, so the processing speed is very slow. It has the following drawbacks.

Therefore, by combining these devices, it is possible to create a device that can process coins at high speed and prevents coins of different types from being sent into the coin sorting path. However, in this case, since the coins are transported by the transport means, problems arise, such as how to transport the coins upstream and downstream of the discrimination section when different types of coins are discriminated.

Separately, with such a combination of conventional devices, even if it is possible to prevent a coin of a different type from entering the coin sorting passage when a coin of a different type passes through the discrimination section, it is difficult to manually remove the coin. need to be removed. Therefore, there is a problem in that the operator must be near the machine at all times during coin processing.

In view of the above points, the present invention is a coin sorting machine that can process coins at high speed, automatically eliminate different types of coins from the coins being processed, and can continue processing coins even if different types of coins are mixed in. It was made with the purpose of providing.

[Structure of the idea]

(Means for Solving the Problems) In order to solve the above-mentioned problems of the prior art, the present invention supplies coins in a mixed state of multiple denominations onto a rotating disk, and uses the centrifugal force generated by the rotation of the rotating disk to move the coins. The coins are moved to the periphery and sent out, and transported to a coin sorting passageway having sorting slots for each denomination arranged in order from small diameter coins to large diameter coins. In a coin sorting machine that transports coins and sorts them into denominations; the entrance portion faces the periphery of a rotating disk, and the exit portion is a denomination discrimination passageway connected to the entrance portion of a coin sorting passage, and detects a denomination discrimination element. a denomination discriminator connected to the denomination discriminator, and a passage bottom opening/closing drive that is activated when the denomination discriminator circuit discriminates different types of coins in order to automatically remove dissimilar coins discriminated by the denomination discriminator circuit connected to the denomination discriminator. a dissimilar coin removal passage section, which is provided with a movable passage bottom member that is moved by a section to open the passage surface; and a coin transport body that rotates synchronously with the coin transport body provided on the coin sorting passage, and faces above the denomination discrimination passage. a coin conveying body provided over substantially the entire area of the denomination discrimination passage in order to transport the coins sent into the denomination discrimination passage to the coin classification passage downstream; a disk drive section that drives the disks; a conveyor drive section that drives each coin conveyor in the denomination discrimination path and the coin classification path; connected to the denomination discrimination circuit, the disk drive section, the conveyance body drive section, and the passageway are connected to the denomination discrimination circuit; A control unit that controls the drive of the bottom opening/closing drive unit, and controls the disc drive unit and the passage bottom opening/closing drive unit to stop or reverse the rotating disc and to move the disc when different types of coins are discriminated by the denomination discrimination circuit. The passage bottom member is moved to open the passage bottom of the dissimilar coin removal passage section, and at this time, regardless of whether the denomination discrimination circuit discriminates between dissimilar coins, the control section operates the conveyance body driving section to continue operating both coin conveyance bodies. By causing the normal transport drive to continue, the removal of different types of coins and the sorting operation of coins in the coin sorting passage are continued, and at a predetermined time after the removal of different types of coins, the control unit operates the passage bottom opening/closing drive unit to close the bottom of the movable passage. a control section that returns the member to close the bottom of the passageway of the dissimilar coin removal passage section and causes the disc drive section to return the rotary disc to a normal rotation state; When this is done, the rotating disk is stopped or reversed to interrupt the feeding of the coins on the rotating disk to the denomination discrimination path, and the normal conveying operation of each coin conveying body is continued, and at this time, the dissimilar coin removal path By opening the bottom of the passageway, different types of coins are removed, and then by closing the bottom of the passageway and returning the rotating disk to normal rotation, the feeding of coins into the denomination discrimination passage is resumed, and the coin sorting and counting process is resumed. It is characterized by this.

(Function) With the above configuration, when different types of coins are discriminated by the denomination discriminating circuit, the feeding of the coins on the rotating disc to the denomination discriminating path is interrupted by stopping or reversing the rotating disc, and each coin is The normal conveying operation of the conveyor is continued, and at this time, the bottom of the different coin removal passage is opened to remove different types of coins, and then the bottom of the passage is closed and the rotary disk returns to normal rotation to clear the denomination discrimination passage. The sending of coins to will be resumed.

Furthermore, a gripping roller 20 is provided on the upper surface of the denomination discrimination path 100 at the entrance facing the rotary disk 2, and a conveyor belt 30 is provided between the starting end pulley 31 and the ending end pulley 32 following the roller 20. is wound. A direction changing pulley 3 is provided in the vicinity of the pulley 32 of the conveyor belt 30.
3 is provided to guide the direction change of the conveyor belt 30 in the right angle direction and to press and hold the belt 30 from the upper surface. Note that the pulley 33 is shaped so as not to come into contact with the coins below the belt 30.

The gripping roller 20 is connected to the rotating disk 2
They are both rotated synchronously by a drive motor _M1 , and the circumferential speed ratio of the rotating disk 2, the gripping roller 20, and the conveying belt 30 is 1.3:1:3 in this embodiment.
When the coins are gripped from the gripping roller 20 to under the conveyor belt 30 by the pulley 31, a sufficient interval is created between the coins, and after the coins have entered under the conveyor belt 30, the coins are conveyed with this interval maintained.

Note that the conveyor belt 30 is driven by another drive motor _M2 .

The end of the passage wall member 7 has a curved concave side surface 34 for guiding the coins 10 along the curvature of the conveyor belt 30.

On the other hand, in the coin sorting passage 200 of the bottom plate 4, sorting slots 5A, 5B...5F are arranged in order from small diameter ones to large diameter ones, and these sorting slots 5A, 5

Guide rollers 44 are provided at intermediate positions between the sorting slots 5A, 5B...5F to guide the movement of the transfer belts 41A, 41B.
floating and horizontal belts 41A, 41
This is a pulley that prevents B from moving. Further, 45 is a positioning roller for guiding the coin to a proper position on the sorting slots 5A, 5B...5F, and 46A to 46E are positioning rollers for each sorting slot 5.
A, 5B, . . . , 5E are provided on the side corresponding to reference rollers having the same diameter and the same shape to define the position on one side of the coin and determine the passage trajectory of the coin with respect to the sorting slots 5A to 5E. Therefore, these reference rollers 46A
-46E are arranged parallel to belts 41A and 41B. On the other hand, the positioning roller 45 has a circumferential surface that corresponds to the reference roller 46 in FIG.
The concave side surface 34 of the passage wall member 7 is located further forward than the peripheral surface of the roller 45. Therefore, conveyor belt 3
The coin below 0 is guided by contacting the curved concave side surface 34,
It is sent under the pulley 32 while gradually changing the transport direction under the conveyor belt 30, and at that point it comes into contact with the circumferential surface of the positioning roller 45 to determine its position, and is moved parallel to the belts 41A and 41B, and during its movement. and comes into contact with the protruding reference rollers 46A to 46E.

On the other hand, the belts 41A and 41B are movably guided in the horizontal direction by a guide roller 43 in the vicinity of the reference roller 46A, and their horizontal movement is restricted by pulleys 32 and 44 before and after the reference roller 46A, so that the belts 41A and 41B are not able to handle coins. No slippage occurs between the belts 41A, 41B, and the change in the course of the coin due to contact with the circumferential surface of the reference roller 46A causes horizontal deflection in the region between the pulleys 32, 44 of the belts 41A, 41B. Belts 41A and 41B due to this deflection
On the contrary, the restoring force of the coin reference rollers 46A to 46
The coin acts as a pressing force against E, and the coin is moved along the circumferential surface of the reference rollers 46A to 46E. Thereafter, when the coin reaches the most protruding point on the circumferential surface of the reference rollers 46A to 46E (the part where the guide roller 43 is provided in FIG. 1), the coin is transferred to the sorting slot 5A.
located above. If the coin is of a denomination corresponding to this sorting slot 5A, the dimension of the most protruding point of the circumferential surface of the reference roller 46A and the opposing edge of the sorting slot 5A is slightly larger than the diameter of the coin of that denomination. As a result, the edge of the coin on the opposite side to the reference roller 46A comes off the bottom plate 4, and the coin is suddenly pushed into the sorting slot by the belts 41A and 41B through the pressing force of the guide roller 43. 5A and stored in a safe (not shown).

Coins that do not match the sorting slot 5A are further moved along the circumferential surface of the reference roller 46A by the pressing force of the belts 41A, 41B and the restoring force in the horizontal direction, and are moved along the path before contacting the reference roller 46A. Will be reinstated.

At this time, it comes into contact with the next reference roller 46B,
The same operation as described above is performed, and the coin is dropped into one of the corresponding sorting slots 5B to 5F, and stored in a deposit box (not shown) for each denomination. Note that the belt 41 in the second and subsequent sorting slots 5B to 5F
The horizontal movement of A and 41B is controlled by pulleys 44 located before and after the sorting slot. Further, the dimensions of the most protruding ends of the circumferential surfaces of the reference rollers 46B...46E and the opposing edges of the sorting slots 5B to 5E are slightly larger than the diameter of the corresponding denomination coin. Furthermore, each safe deposit box for coins of 550 yen to 1 yen is provided with sensors 500SW to 1SW for detecting whether the stored coins are full or not.

Belts 41A, 41 of this coin sorting passage 200
B is also rotated synchronously with the belt 30, and the drive motor _M2
It is rotated by

As shown in FIGS. 2 and 3, the dissimilar coin removal passage section 101 has a coin discharge hole 102 (groove or hole) formed by a cutout slot in the bottom plate 4, and a part of the widthwise direction of the discharge hole 102 is formed. A movable passage bottom member 103 that is closed (the position in FIG. 2 is the home position) is provided.

The passage section 101 has a length in the front-rear direction that is slightly longer than the diameter of the largest coin to be processed, and has a length that prevents two coins from being conveyed at the same time with an interval between them. A coin ejection hole 102 in the shape of a notch with the remaining bottom plate 4A of about 1/3 of the passage width left on one side and open on the other side, and this ejection hole 10.
A portion approximately the same width as the remaining bottom plate 4A of No. 2 is located within the denomination discrimination passage 100, and the remaining bottom plate 4A
A movable passage bottom member 103 having a bottom plate constituting surface portion 103A that cooperates with the bottom plate to allow non-ejected coins to pass; a position where this bottom member 103 is placed in the same plane as the passage bottom plate 4 (the position shown by the solid line in FIG. 3); It consists of a passage bottom opening/closing drive unit for moving the denomination discrimination passage 100 to a position outside the passage width range (the position shown by the chain line in FIG. 3). In the embodiment shown in the figure, the structure of the passage bottom opening/closing drive unit for moving the movable passage bottom member 103 is such that an arm 1 is attached to the outer upper surface thereof as shown in the third figure.
04B is established, and the upper end of this arm 104B is pivotally supported by a pin 107 to a boss portion 106 of a frame 105, and a plunger 104A of a solenoid 104 as an electric drive unit is connected to the midpoint of this arm 104B. . Furthermore, when the solenoid 104 is de-energized, the movable passage bottom member 103

A driven pulley 33A as a pressing rotary body is provided in pressure contact with the upper surface of the lower running side belt portion of the transfer belt 30 at a position almost directly above the coin ejection hole 102, and the coins are ejected from the coin ejection hole 10 at this portion.
The presence of this driven pulley 33A provides a function for forcibly discharging the fluid into the container 2 (33A is not shown in FIG. 1).

A reject box (not shown) is installed directly below the coin ejection hole 102, and coins ejected through the coin ejection hole 102 are collected in this redirect box and can be returned.

8 and the stopper 109, the movable passage bottom member 103 is in the position shown by the solid line in FIG. The passage bottom member 103 is moved to the position shown by the chain line in FIG. 3, and the foreign coins are removed.

On the other hand, the circuit configuration of this invention is as shown in Fig. 4, and it has a CPU (microcomputer, etc.) 50 that performs overall control.
The CPU 50 stores control programs, etc.
A ROM 51 and a RAM 52 for writing and reading necessary data are connected via a bus lance, and these constitute a control section 53. Further, a motor M ₁ for driving the rotating disk 2 and the roller 20, a motor M ₂ for driving the belt 30, the belts 41A and 41B, and a solenoid 104 are each connected to the CPU 50 via a bus line.

Each detection signal from the magnetic sensors 11A to 11F is input to a counting circuit 56, where the data counted for each sensor is transferred to the RAM 52, and a numeric keypad TK for inputting numerical data,

STK, stop key STP for instructing to stop operation, and clear key CLK for clearing stored information are also input to the CPU 50.
In addition, a sensor 500 installed in each deposit box
Each signal from SW to 1SW is also input to the CPU 50 to grasp the state of coin storage in the deposit box. The coin passing through the denomination discrimination path 100 has a denomination discrimination element detected by a magnetic sensor 9 and optical sensors 10 and 10 serving as a denomination discriminator 8A, and a denomination discrimination circuit 8B to which the detection signal is input.
The denomination of the coin is determined and the number of coins for each denomination is counted, and the data is sent to the RAM5 via the bus line.
2 is now stored in memory.

Here, an example of the memory area in the RAM 52 is shown in FIG. 5 and explained. The RAM 52 includes an optical sensor counting memory area 521, a passage counting memory area 522, a discrepancy flag area 523, a number setting memory area 524, and a magnetic sensor counting memory area 521. It has a counting memory area 525. The optical sensor counting memory area 521 is divided into denominations that are counted by adding "+1" to each denomination according to the denomination signal detected by the magnetic sensor 9, the optical sensors 10, 10, and the denomination discrimination circuit 8B. The magnetic sensor counting memory area 525 stores the values counted by the counting circuit 56 of the detection signals of the magnetic sensors 11A to 11F for each sensor. Counting memory 1 that is transferred and stored as is
It consists of 1AM to 11FM. The passage counting memory area 522 stores the number of coins of each denomination determined by calculating the difference between the values of adjacent counting memories counted and stored in the magnetic sensor counting memory area 525. Counting memory 1
SE (1 yen coin) to 500 SE (500 yen coin), and the discrepancy flag area 523 compares counting memories 1PT to 500PT and 1SE to 500SE, and when they do not match, it is turned from off to on. It has discrepancy flags 1FL to 500FL. In addition, the number set memory area 524 is a memory 1ST (1
yen coin) to 500ST (500 yen coin),
CPU50 is counting memory area 5 for optical sensor.
21, and when the values match, a bottom member 103 is actuated by energizing a solenoid 104 to prevent subsequent coins from being sent to the coin sorting path side.

The operation of such a configuration will be explained with reference to the flowchart shown in FIG.

When the sorting operation of the sorting machine as described above is instructed by the start key STK, coin sorting and counting processing are executed (step S ₀ ). At this time,
All of the discrepancy flags 1FL to 500FL are turned off, and the coin 15 in the rotary disk 2 is sent to the denomination discrimination path 100 as described above. A denomination discrimination element is detected by the sensors 10, 10, a signal for detecting the denomination and number of coins is obtained by the denomination discrimination circuit 8B, and a calculation of "+1" is performed via the CPU 50 corresponding to the denomination. and stored in the corresponding denomination memory in the optical sensor counting memory area 521. The coins conveyed to the coin sorting passage 200 via the denomination discrimination passage 100 are sorted according to their diameters by the sorting slots 5A to 5F as described above, and are also sorted by the magnetic sensors 11A to 11.
F, and the detection signal is sent to the counting circuit 5.
6, and the counted value is sequentially transferred to and stored in the magnetic sensor counting memory area 525. Each count value of the counting circuit 56 is calculated by the magnetic sensor 11.
As the coins A to 11F are detected, they are each incremented by "+1", so the coins 15 that have fallen into the deposit box through the sorting slots 5A to 5F are not detected by the downstream magnetic sensor. Therefore, the number of coins (1 yen to 500 yen) passing through the magnetic sensor 11A is the largest, and the number of coins (500 yen) passing through the magnetic sensor 11F is the smallest, and the number of coins (1 yen to 500 yen) passing through the magnetic sensor 11A is the smallest. ~1
The number of detected sheets decreases in the order of 1F. Therefore, the values stored in the counting memories 11AM to 11FM of the magnetic sensor counting memory area 525 are as follows.
The value of counting memory 11AM is the largest, and decreases as the value of counting memory 11FM increases.

Once the coins are sorted and counted in this way, the sensors 500SW to 1 detect whether each deposit box is full of coins.
This is determined via the SW (step S ₁ ), and if none of the deposit boxes are full, it is determined whether or not there are no coins in the rotating disk 2 (step S ₂ ). If there are coins in the rotating disk 2, the number set in the number set memory area 524 using the numeric keypad TK is compared with the value stored in the optical sensor counting memory area 521, and then It is determined whether or not there are coins of the same denomination with the same number of coins (step _S3 ).

If there are coins but no coins with the same number of coins, and the denomination discrimination unit 8 has not discriminated between different types of coins, the process returns from step _S23 to step _S0 ,
The classification and counting process described above is repeated.

Further, when the denomination discriminating section 8 discriminates between different types of coins, steps _S23s to _S26 are carried out, but during the period of _S23 to _S25 of this step S, the denomination discriminating section 8 does not discriminate between denominations. Coins passing through the container 8A, for example,
Even if there are different types of coins or coins of the next rank, those coins are not counted. Meanwhile, in step S ₂₄ motor M ₁
is reversed, rotating disk 2 and roller 20 are reversely rotated, and solenoid 104 is energized. Since motor _M2 continues to rotate, belts 30, 41A,
41B continues to rotate normally, different types of coins are removed from the hole 102, and the coins in the passage 200 continue to be sorted.

Thereafter, the solenoid 104 is de-energized, the motor _M1 rotates forward, and the process returns to step _S0 .
The counting operation is repeated.

On the other hand, if the deposit box of any denomination is full of coins, if there are no more coins in the rotating disk 2, or if the coin count setting memory area 5
When the number of coins reaches the set number of coins 24, the solenoid 104 is energized and the motor _M1 stops, the denomination discriminator 8 does not count coins after the set number, and the motor _M2 stops after a certain period of time. . The number of coins of each classified denomination is calculated from the number data counted and stored in the magnetic sensor counting memory area 525 (step S ₆ ).

This calculation is performed by subtracting each adjacent data in the count memories 11AM to 11FM. That is, by subtracting the number of coins in the adjacent counting memory 11BM from the number of coins in the counting memory 11AM, the number of one yen coins that have passed through the magnetic sensor 11A can be calculated, and this number data is stored in the counting memory 1SE. Similarly, by subtracting the number of coins in the adjacent counting memory 11CM from the number of coins in the counting memory 11BM, the number of 5 yen coins passing through the magnetic sensor 11B can be calculated.
Store this number of 5 yen coins in counting memory 5SE,
Similarly, the number of coins is stored in the counting memory 10SE, the number of 50 yen coins in the counting memory 50SE, the number of 100 yen coins in the counting memory 100SE, and the number of 500 yen coins in the counting memory 500SE. In addition,
The number of 500 yen coins is the value stored in the counting memory 11FM.

In this way, by subtracting the count data of the adjacent memories 11AM to 11FM of the count memory area 525 for the magnetic sensor, the number of classified coins for each denomination is determined, and the count memories 1SE to 11FM are calculated. When stored in 500SE, comparison with the count data of count memories 1PT to 500PT of optical sensor count memory area 521 is performed according to steps _S7 to _S16 . That is, the values in counting memory 500PT and counting memory 500SE are compared to determine whether they match (step
_S7 ), and if they do not match, the mismatch flag 500FL corresponding to the 500 yen coin is turned on (step _S8 ). If they match, the mismatch flag 500FL remains off. Similarly, the data in counting memory 100PT and counting memory 100SE corresponding to the 100 yen coin are compared (step _S9 ), and if the two do not match, the mismatch flag 100FL for the 100 yen coin is set.
Turn on (step _S10 ). Similarly, a comparison operation is performed for each of the 50 yen coin, 10 yen coin, 5 yen coin, and 1 yen coin, and after these comparison processes, it is determined whether or not there is a flag turned on in the discrepancy flag area 523. (Step _S19 ) If no flag is turned on, the number of coins of all denominations that have passed through the optical sensor section and the number of coins that have been sorted in the sorting passage 200 are completely different. Since they match, the operation ends with no erroneous counting.

On the other hand, if there is a flag that has been turned on, an alarm is outputted via the alarm device 57 such as a buzzer or lamp (step _S20 ) to notify the operator etc. that an erroneous count has occurred. Then clear key
By pressing CLK, the data in each memory area in the RAM 52 is cleared, and the mismatch flag area 523 is also all reset and turned off (steps S ₂₁ and S ₂₂ ).

In the above-described embodiment, the number of coins in each classification is calculated after the classification counting process is stopped, but during the classification process, the magnetic sensors 11B to 1
When the 1F detects a passing coin, the counting memory 11AM to 11 corresponding to the sensor one upstream
The calculation of "-1" from the value of EM may be performed in parallel.

Furthermore, in the above-described embodiment, the number of coins in the counting memory is checked in order from 500 yen coins to 1 yen coins, but this order can be changed arbitrarily.

Further, the denomination discriminator 8A of the denomination discriminator 8 may use either the optical sensor 10 or the magnetic sensor 9.

Next, to supplement steps S ₄ and S ₅ in _FIG .
It is not sent to the 00 side, and the denomination discrimination passage 10
Even if there is such a coin by the zero sensor 10, 10, the coin is discharged to the discharge hole 102. Furthermore, the denomination discriminating section 8 does not count these coins.

The roller 20 and the coins on the rotating disk 2 are driven by a motor.
A stop or reversal of M ₁ prevents it from being sent downstream in passage 100.

On the other hand, motor _M2 is stopped after a certain period of time after motor _M1 is stopped. This is the time to allow for the sorting of coins in aisles 100 and 200 to be completed.

Note that motor _M1 may be reversed in step _S4 , in which case motor _M1 and motor _M2 will be stopped in step _S5 .

Also, to add more information about steps _S23 to _S26 in FIG. 6, the reversal of motor _M1 in step _S24 is
It may also be a case where M ₁ is stopped. In other words, instead of rotating the rotating disk 2 and the roller 20 in the normal direction, the rotating disk 2 and the roller 20 may be reversely rotated or stopped so that the coins are not sent to the downstream side of the denomination discrimination path 100.

When the coin is determined to be a different type of coin in step _S23 , the coin is sent from the magnetic sensor 9 to the optical sensor 10,1.
0, and the next coin is either below the roller 20 or on the top surface of the rotating disk 2.

Also, coins that advance ahead of different types of coins are discharged through the ejection hole 102.
is at the end of the passage. Therefore, the denomination discrimination section 8 (8
A and 8B combined) is solenoid 104
When energized, in principle, only coins of different types are discharged to the discharge hole 102.

Here, at the time when a different type of coin is discriminated by the denomination discriminating section 8, the next coin may be in the middle of being gripped from the roller 20 to the belt 30. In this case, if the bottom member 103 is closed immediately after a different type of coin is ejected into the discharge hole 102, the timing delay will cause the coin (the next different type of coin) to be There is also a possibility that the coins may become clogged. Therefore, the predetermined time during which the solenoid 104 is de-energized (step S ₂₅ ) is set to ``assuming that the next coin of the different type exists under the roller 20, and a sufficient time for that coin to also be ejected to the ejection hole 102.'' ” is set.

Note that the denomination discriminator 8A calculates the time from when different types of coins are discriminated until the normal rotation of the motor _M1 (steps _S23 to _S25 ).
Coins that have passed through the denomination discriminator 8A (actually, coins of a different type and the next coin under the roller 20 and discharged to the discharge hole 107) are not counted. As a result, the counted value for each denomination by the denomination discriminator 8 matches the counted value for each denomination by the magnetic sensors 11A to 11F, etc., and an alarm is issued when the two do not match, so that the coin classification work can be performed with certainty. is guaranteed.

The coin conveyor in the denomination discrimination path 100 of the present invention is the conveyor belt 30 in this embodiment,
Although it is separate from the conveyor belts 41A, 41B as an example of a coin conveyor in the coin sorting path 200, it may be used for both, and one starting end of the conveyor belts 41A, 41B may be wound around the pulley 31. Moreover, each coin conveying body may be a plurality of roller groups instead of a belt. Furthermore, for example, the coin conveyor in the coin sorting passage has two belts 41A,
41B, it may be one belt, or it may be provided with a plurality of conveyor belts corresponding to the sorting slots 5A to 5F. One side wall of this coin sorting passage is a reference roller 46A.
Although the structure is defined by 46E, for example, it may be in the form of a fixed plate like the passage wall member 7. Also, the denomination sorting slot 5 of this passage 200
A to 5F have hole shapes, but may have continuous groove shapes. Although the disk drive section and the conveyance body drive section of the present invention each have drive motors M ₁ and M ₂ , the rotation of one common motor may be transmitted to the disk or the coin conveyance body through an electric clutch. Often, in that case, the common motor and the disc clutch serve as the disc drive, and the common motor and the carrier clutch serve as the carrier drive. The solenoid 104 may be replaced with a rotary solenoid or a motor.

[Effect of idea]

As explained above, the present invention provides a denomination discrimination passage between the centrifugal rotating disk and the coin sorting passage having a denomination sorting slot, and when different types of coins are discriminated by the denomination discrimination circuit. , by stopping or reversing the rotating disk, the feeding of the coins on the rotating disk to the denomination discrimination passage is interrupted, and the normal conveying operation of each coin conveying body is continued; By opening the door, coins of different types are removed, and then by closing the bottom of the passage and returning the rotating disk to normal rotation, the feeding of coins into the denomination discrimination passage is restarted, and the coin sorting and counting process is restarted. , when different types of coins are discriminated, the different types of coins are automatically and reliably removed from the denomination discrimination path, and at this time, the coins in front of the different types of coins are reliably removed from the coin sorting path by each coin carrier that continues its normal transport operation. are categorized. After different types of coins are removed, coin sorting and counting is automatically restarted, which speeds up coin processing and automatically removes different types of coins and restarts counting after that, without the need for human intervention. This provides an excellent effect that allows coin processing to be carried out without any trouble and greatly contributes to increasing the processing efficiency of coin sorting work.
