DETAILED DESCRIPTION OF THE INVENTION (al) Industrial Application Field This invention relates to a coin ejecting device used in automatic ticket vending machines and the like.

(b1 Summary of the Invention In summary, the coin discharging device according to the present invention is capable of storing a plurality of coins in at least one of a plurality of coin guide holes bored in a disc, and is capable of storing a plurality of coins in at least one of a plurality of coin guide holes formed in a disc. By providing a guide moving means for moving the guide that contacts the stored coins between the contact position and the retracted position,
FCL is a device which is designed to keep coins reliably stored in the coin guide hole at all times and to quickly and reliably eject the required number of coins.Prior art Fig. 5 shows a plan view of a general coin ejecting device. A coin discharge port 55 is provided on the bottom side of the hopper 52.

Further, on the inner surface of the hopper 52, a disc 51 is rotatably supplied with rotational force from a motor (not shown). The upper surface of the disk 51 is formed into a conical shape, and five coin guide holes 54 are bored at equal intervals from the upper surface. A discharge air 57 is formed on the outer periphery of the lower surface of the disc 51 in correspondence with each coin guide hole 54 . This discharged wind 57 is generated by the disk 51
When the coin rotates in the direction of arrow B, the disc 5 is removed from the coin guide hole 54.
1, that is, the bottom of the hopper 52.

A guide plate 53 is provided near the coin discharge port 55 on the bottom surface of the hopper 52. This guide plate 53 comes into contact with coins that are being moved by the discharge wind 57 and guides the coins to the coin discharge port 55. A rotor 56 is pivotally supported on the outside of the coin ejection port 55, and detects that a coin is ejected.

In the above coin discharging device, when a coin is stored in the hopper 52 and a coin discharging signal is input to the control unit that controls the device, the disc 51 is moved in the direction of arrow B by the rotation of the motor. Rotate to . When the disk 51 rotates, the coin 60 slides on the conical upper surface of the disk 51 and falls into the coin guide hole 54. At the same time, the coin 60 is moved in the direction of arrow B by the pressure of the discharged air 57. When the coin 60 approaches the vicinity of the coin discharge port 55, it is guided toward the coin discharge port 55 by contact with the guide plate 53. The discharge air 57 that discharges the coins 60 to the outside passes through the coin discharge port 55 and the guide plate 53 and moves in the direction of arrow B.

The above operation is performed for each coin guide hole 54, and the required number of coins are released one after another.

(d) Problems to be Solved by the Invention However, in the conventional coin discharging device described above, each of the plurality of coin guide holes provided in the disk can only accommodate one coin, When discharging a coin, the number of coin guide holes must pass through the coin discharging port, and discharging a large number of coins requires a long time. In order to shorten this discharge time, it is possible to increase the number of coin guide holes provided in the disk, but the number of coin guide holes is limited by the inner diameter of the hopper and the diameter of the coin concubine, and is more than a predetermined number. cannot be increased to Another possibility is to increase the rotation speed of the disk, but if the disk is rotated too fast, the coin will not be stored in the coin guide hole after passing through the coin ejection port and before reaching the coin ejection port. In some cases, the coin ejection operation becomes uncertain, and
There was a drawback that the release rate was low.

In view of these conventional problems, an object of the present invention is to enable a plurality of coins to be stored in at least one of the coin guide holes formed in a disc, and to selectively bring the guide and the coins into contact with each other. The purpose of the coin discharging device of the present invention is to provide a coin discharging device that can reliably and quickly discharge a required number of coins by At the bottom of the hopper, which forms the outlet bottom and stores coins inside, there is a rotatable disc and a rotatable disc with holes drilled from the top of the disc (each of which stores multiple coins). a guide hole; a motor that supplies rotational force to the disc; a guide fixed near the coin ejection port that comes into contact with the coins stored in the coin guide hole and guides the coins to the coin ejection port; The present invention is characterized in that it is provided with a guide moving means for moving the coin between a contact position where it contacts the coin and a retracted position where it does not contact the coin.

(') Function In the present invention, a plurality of coins are stored in at least one of the coin guide holes formed in the disc.

The guide selectively contacts the coins stored in the coin guide hole by the guide moving means. In a coin guide hole that stores a plurality of coins, any number of coins that are less than or equal to the number of coins that are stored selectively abuts against the guide. Coins that abut the guide are guided to the coin ejection port and ejected to the outside. Therefore, any number of coins can be ejected from the coin guide hole.

(gl Embodiment FIG. 1 is a front sectional view of a coin ejecting device which is an embodiment of the present invention.

A motor M1 is provided below the bottom surface 14 of the hopper 2. The rotating shaft 8 of this motor M1 is exposed on the inner bottom surface of the hopper 2, and the disc 1 is pivotally supported on this exposed portion. The disk 1 is the disk 5 of the conventional coin ejecting device shown in FIG.
It is formed in the same planar shape as 1. That is, coin guide holes 4 are bored at five locations on the conical top surface.

In each coin guide hole 4, four coins 20 are stored between the lower surface of the disk 1 and the bottom surface 14. Hopper 2
A coin ejection opening 5 is formed in a part of the bottom surface. The height of this coin discharge port 5 is set to a height that allows four coins 20 to pass through.

A guide 3 is located near the coin discharge port 5 on the bottom surface 14. A threaded portion 13 is formed in the connecting portion 3a fixed below the guide 3. As shown in FIG. This threaded portion 13 meshes with a rotating threaded portion 12 formed on the rotating shaft 11 of the motor M2. The rotation of the connecting portion 3a and the guide 3 is restricted, and when the motor M2 rotates, the guide 3 moves in the direction of arrow C between the contact position shown by the solid line in the figure and the retracted position shown by the two-dot chain line.
Or move straight in the D direction. When the guide 3 is in the contact position, it contacts the coin 20 stored in the coin guide hole 4 and guides the coin to the coin discharge port 5.

When the guide 3 is in the retracted position, it does not come into contact with the coin 20. In addition, by controlling the amount of rotation of the motor M2, the amount of movement of the guide 3 is adjusted, and the coin 2 that comes into contact with the guide 3 is
You can select the number of 0 sheets. This motor M2, rotating screw part 1
2 and the threaded portion 13 are the guide moving means of the present invention, and are the abutment variable number moving means. From the above, the number of coins 20 that come into contact with the guide 3 can be selected between 0 and 4, and the number of coins 20 that come into contact with the guide 3 can be sent to the coin ejection port 5.
It can be released from

FIG. 2 is a block diagram of the control section of the coin discharging device.

A coin release signal is input to the CPU 21 from the outside via the I10 interface 24. This coin discharge signal includes data on the number of coins to be discharged, and the CPU 21 calculates the rotation amount of the motor M2 according to the data on the number of coins to be discharged according to a program written in the ROM 22. RAM23
A part of is allocated to the working area for this calculation. The control data for the motor M2 obtained by the calculation is sent from the I10 interface 24 to the motor driver 2.
5 is output. Motor driver 25 drives motor M2 according to this control data. Further, the motor driver 25 drives the motor M1, and the rotation amount of this motor M1 is determined by the low-return encoder 26 as rotation amount data I1.
0 interface 24 to the CPU 21.

The CPU 21 knows the current position of the disk 1 by looking at this rotation amount data.

FIG. 3 is a flowchart showing the processing procedure of the coin discharging device.

When a coin release signal including the number N of coins released is input (nl)
, Compare the number N of coins released and the number K (here = 4) stored in the coin guide hole 4 (n2), If the number N of coins released is less than the number of coins stored, drive the motor M2 to move the guide 3
is moved in the direction of arrow C to the Nth stage position (n3). This allows the guide 3 to come into contact with N coins. From this state, Ml is driven (n4) to rotate the disk 1. As the disc 1 rotates, the guide 3 comes into contact with N coins 20 and guides the coins to the coin discharge port 5. Here motor M
The driving amount of 1 is enough to rotate the disk 1 115 times.

When the coin discharge is completed, a discharge completion signal is transmitted to an external device (n5), and the motor M2 is reversed to move the guide 3 to the retracted position (n6). Next, the motor M1 is driven to rotate the disc 1 a predetermined number of times (nl), at which time a predetermined number of coins are stored in all of the coin guide holes 4.

If the number N of discharged sheets exceeds the number K of stored sheets, the motor M2 is turned on and the guide 3 is moved to the next step (n9). This allows the guide 3 to come into contact with all the coins 20 stored in the coin guide hole 4. From this state, the motor M1 is driven (n1o) and the disc 1 is rotated 115 times. As a result, while the next coin storage hole 4 passes through the coin ejection port 5, the guide 3 comes into contact with a coin, and this coin is transferred to the coin ejection port 5.
lead to. Next, set the value of the number of sheets to be released N to (N-K) n1
l), compare the number of sheets released N and the number of sheets stored (n2)
. This process of n2→n9 to nil→n2 is repeated until the number of discharged sheets N becomes equal to or less than the number of stored sheets. When the number N of ejected sheets is equal to or less than the number of stored sheets, steps n3 to n7 are executed.

As described above, according to the embodiment, a plurality of coins can be stored in all of the coin guide holes 4, and
By making it possible to select the number of coins that the guide 3 contacts, it is possible to quickly release the required number of coins. Also, after releasing the required number of coins, guide 3
Since the disk 1 is rotated a predetermined number of times without contacting the coins, it is possible to store a predetermined number of coins in all the coin guide holes 4 before the next coin ejection operation (see FIG. 4). A) and (B) are a plan view and a front sectional view showing another embodiment of the present invention.

Four coin guide holes 104a to 104d are bored in the disc 101. On the lower surface of the disk 101, a mounting table 109 is provided at a position facing the coin guide holes 104a to 104C.
a-109c is pivotally supported. These mounting tables 109a
-109C are all urged by a spring 110 in the direction of being exposed to the coin guide holes 104a-104C.

The space between the lower surface of the disk 101 and the bottom surface 14 is set at a height that can accommodate five coins. On the other hand, one coin can be stored between the lower surface of the disk 101 and the mounting table 109a, and the disk 1
Two coins can be placed between the lower surface of the disk 101 and the mounting table 101b, and three coins can be stored between the lower surface of the disk 101 and the f2 mounting table 109C. From the above, each of the coin guide holes 104a to 104d can accommodate 1, 2, 3, and 5 coins, respectively. Furthermore, discharge air 107a to 107d are formed on the lower surface of the disc 101 at positions facing the coin guide holes 104a to 104d. This discharge wind 1
Each of 07a to 107d is set at a height that makes contact with 1, 2, 3, and 5 coins. Note that the state of the disc 101 is detected by the rotation amount data from the rotary encoder as in the previous embodiment. Therefore, each coin guide hole 1
The position of 04a=104d is always grasped by the CPU.

With the above configuration, the circle vi101 rotates in the direction of arrow B, and when the coin guide holes 104a to 104d pass through the guide 103, the coins stored on the mounting tables 109a to 109C and the bottom surface 14 come into contact with the guide 103. The coin is guided to a coin discharge port (not shown) by contact with the guide 103 and pressure by the discharge winds 107a to 107d. Incidentally, when the coin guide holes 104a to 104c pass through the position of the guide 103, the direction indicated by the arrow E is caused by contact with the guide 103.
Rotate in the direction. When the disk 101 further rotates in the direction of arrow B and the mounting tables 109a to 109c no longer come into contact with the guide 103, the elastic force of the spring 110 returns them to the position facing the coin guide holes 104a=104c. As a result, 1, 2, and 3.5 coins are always stored in each of the coin guide holes 104a to 104d.

When the coin ejection signal is received, the guide 103 waits at the retracted position until the coin guide hole containing the number of coins corresponding to the number of ejected coins comes in front of the guide 103. When the coin guide hole corresponding to the number of coins to be ejected reaches this side of the guide 103,
Solenoid SQL 1 is turned on, and guide 103 moves in the direction of arrow G to a position where it contacts the lower surface of disk 101. When the disk 101 further rotates in the direction of arrow B in this state, all of the coins stored in the coin guide holes are released. In this embodiment, the solenoid 101 corresponds to a guide moving means, and the coin guide holes 104a to 104d are individual coin guide holes.

As described above, according to this embodiment, different numbers of coins can be stored in each of the coin guide holes 104a to 104d provided in the disc 101, and the guide 103 can be moved to the contact position or the retreat position. You can release the required number of coins by doing this. For example, when releasing 6 coins, 104a to 104c or 1
Guide 103 for hard guide holes 04a and 104d
By exposing the coins, you can release the desired number of coins.

(H1 Effects of the Invention According to this invention, the number of coins to be brought into contact with the guide can be arbitrarily selected by the guide moving means, and the number of coins to be ejected can be quickly brought into contact with the guide. Also, the guide can be moved to the retracted position. , the coins are not ejected even if the disk is rotated, so the disk can be rotated a predetermined number of times after the coins are ejected, and thereby a predetermined number of coins can always be stored in the coin guide hole. Therefore, when discharging a large number of coins, the dispensing time can be shortened.
