Description

[Detailed description of the invention] [Industrial application field] The present invention is applicable to game machines such as vending machines, currency exchange machines, and slot machines that use coin-shaped medals. This invention relates to a coin dispensing device for dispensing coins to a dispensing outlet, and particularly relates to a coin dispensing device that rotates a disk horizontally and dispenses coins by utilizing centrifugal force at that time.

[Prior Art] A conventional coin dispensing device has a rotating disk driven by a motor arranged at an angle of about 60 degrees with respect to the horizontal, in a bucket containing a large number of coins to be dispensed. Since the structure was such that the weight of the coins in the bucket was applied directly to the underside of the rotating disk, giving a large load to the rotating disk, it was difficult to speed up the drive of the rotating disk and improve coin dispensing efficiency. It was hot.

Therefore, by rotating the rotating disk horizontally and dispensing coins using the centrifugal force at that time, it was possible to speed up the drive of the rotating disk and significantly improve coin dispensing efficiency. A coin dispensing device has been proposed, and a patent application has been filed by the present applicant (Japanese Patent Application No. 108401/1983).

This coin dispensing device consists of a coin storage bucket with an opening formed at the bottom, a rotating disk placed below the bucket so as to be driven to rotate almost horizontally, and coins that are moved outward by the rotation of the disk. It is equipped with a guide plate that guides the coins to the ejection port while receiving the outer edge of the bucket, and a regulation plate that receives the coins in the bucket above the opening. By receiving the coins, the load due to the weight of the coins is not directly applied to the rotating disk, and even if the regulating plate is surrounded by a large number of coins, the rotating disk can rotate independently of them. In addition, even if a large number of coins are stored in the bucket, the coins that have entered below the regulation plate will not be subjected to a large load.
By providing a protrusion on the rotating disc facing the bucket opening and stirring the coins with this protrusion,
This prevents coins from jamming, which tends to occur near the opening of the bucket.

[Problems to be solved by the invention] However, in the case of the coin dispensing device that rotates the rotating disk in the horizontal direction, a large number of coins supplied onto the rotating disk through the bottom opening of the bucket are When moving toward the ejection side, the inner coin is pushed against the side of the protrusion provided on the rotating disk, and some of the coins tend to overlap.
Therefore, if the coin reaches the outlet in an inclined state, the coin will become jammed there. That is, by providing a protrusion on the rotary disk in order to prevent coins from getting jammed near the opening of the bucket, there has been a problem in that coins are more likely to get jammed at the coin dispensing opening.

The present invention was developed in view of these problems, and at the same time prevents coins from getting jammed near the opening of the bucket, and at the same time prevents coins moving with the rotating disk from overlapping, thereby preventing coins from getting jammed at the payout opening. It is an object of the present invention to provide a coin dispensing device that also prevents the occurrence of coins.

[Means for Solving the Problems] In order to achieve the above object, the present invention includes a coin storage bucket having an opening formed at the bottom, a coin storing bucket arranged below the bucket so as to be driven to rotate approximately horizontally, A rotating disk that moves coins supplied from the opening of the bucket outward by centrifugal force, a guide plate that guides the coins to the ejection port while catching the outer edge of the coin that moves outward due to the rotation of this disk, and In the coin dispensing device, the coin dispensing device includes a regulation plate that receives coins in a bucket at an upper side, and a regulation plate that receives coins in a bucket on the rotating disc, inside a bottom opening of the bucket,
A support that rotates together with the disc is erected, and the support is provided with a protrusion that projects laterally.

[Function] In the coin dispensing device of the present invention, the coins stored in the bucket drop into the rotating disk from the lower side of the regulation plate through the bottom opening of the bucket, and
It moves outward due to the centrifugal force of the rotating disk, and is guided to the discharge port while being caught by the guide plate.
When coins are moved in this way, the coins that pass through the bottom opening of the bucket hit the protrusions that protrude horizontally above the rotating disk, causing multiple coins to overlap and fall into the bottom opening of the bucket. The coins do not move while stacked on the rotating disk, preventing coins from clogging at the bottom of the bucket or the outlet.

[Embodiments] Hereinafter, embodiments of the present invention shown in the accompanying drawings will be described.

FIG. 1 is a perspective view showing the overall structure of the coin dispensing device according to the present invention. It has a casing 3 formed upright, and a funnel-shaped coin storage bucket 4 with a circular bottom cut out is fixed inside the casing 3. A pillar 6 extending to a predetermined height inside the bucket 4 is arranged at the center of a circular opening 5 formed at the bottom of the bucket 4, and a circular flange 6a is formed at the lower end of the pillar 6 to facilitate rotation. The support column 6 is fixed on a disk 9, and is rotated together with the rotary disk 9 by a gearbox 8 whose drive source is a motor 7 provided under the base 1.

Above the base 1 below the bucket 4 is the support 6.
A disc 9 on which a disc 9 is erected is arranged to be horizontally rotatable, and a guide plate 10 formed in a cylindrical shape is fixed so as to surround the outer peripheral edge of the rotary disc 9. The guide plate 10 is erected at a position close to the outer periphery of the rotating disk 9 so that it can rotate, but there is a gap smaller than the radius of the coin 11 between the outer periphery of the disk 9 and the guide plate 10. It's okay if there is. Moreover, as is clear from FIG. 2, a part of the guide plate 10 is
It is formed as a bent portion 10a that extends above the rotating disk 9, and a horizontally long slit 12 for discharging coins is provided at the lower edge of this bent portion 10a. The height and width of this slit 12 are set so that only one horizontal coin 11 can pass through it.

Further, as shown in FIG. 3, the rotating disk 9 is placed on a mounting base 14 fixedly connected to the output shaft 8a of the gearbox 8, and is mounted between the lower end flange 6a of the support column 6 and the mounting base 14. It is tightened and fixed with screws.

The above configuration of the illustrated embodiment is similar to the coin dispensing device according to the above-mentioned patent application, but according to the present invention, the support 6 is located inside the bottom opening 5 of the bucket bag 4 and above the rotating disk 9. A protrusion 15 projecting laterally is provided at the lower end of the holder. This protrusion 15 stirs the coins 11 falling in from the bottom opening 5 of the bucket 4, while the rotating disk 9
By being located above and protruding sideways, even when a large number of coins 11 supplied on the rotating disk 9 move to the discharge side together with the rotating disk 9, the coins are stirred so as not to overlap. This also prevents coins from clogging in the coin ejection slit 12.

Next, a circular regulating plate 16 is attached to the upper end of the support column 6 so as to be rotatable in the horizontal direction, and this regulating plate 16 is configured not to rotate together with the rotary disk 9. By receiving the large number of coins 11 housed in the bucket bag 4 with the regulating plate 16, the load due to the weight of the coins is not directly applied to the rotating disk 9, and the regulating plate 16 is surrounded by the large number of coins. This is to allow the rotating disk 9 to rotate independently of this.

Near the outside of the slit 12 formed in the guide plate 10, there is a groove made of an elastic material (for example, rubber).
A roller 21 is arranged. This roller 21
is provided to send out the coin 11 ejected from the slit 12 to the chute 22, and the roller 2
Belt 24 wound around shaft 23 to which 1 is fixed
It is rotationally driven by the output shaft 8b of the gearbox 8 via. In addition, as shown in FIG.
When disposing the roller 21 above the rotating disk 9, it is preferable to prevent the roller 21 from coming into contact with the rotating disk 9, but the rotational speed of the rotating disk 9 and the roller 21 may be adjusted relative to each other so that the rotation of both is controlled. They may be brought into contact as long as they do not interfere with each other.

A coin sensor pin 25 protrudes from an elongated hole bored on the base 1 at a position between the roller 21 and the entrance of the chute 22 and in contact with the coin 11 sent out by the roller 21. This coin sensor pin 25 is attached to the support shaft 2 by a tension spring 26.
Lever 2 biased counterclockwise around point 7
The coin 12 sent out by the roller 21 contacts and pushes the coin sensor pin 25 to rotate the lever 28 clockwise, and then reaches the chute 22. It's becoming like that. Since the rotation of the lever 28 is repeated every time the coin 11 passes, an optical sensor 29 for counting the number of rotations is attached to the base 1 to detect the number of coins sent out by the roller 21.

Since the illustrated embodiment is constructed as described above, its operation is as follows.

First, in order to pay out a predetermined number of coins, when the rotary disk 9 is rotationally driven by the motor 7 via the gear box 8, the coins 11 stored in the bucket 4 are transferred from the bottom side of the regulation plate 16 through the bottom opening. 5 and is dropped onto the rotating disk 9. At this time, the protrusion 15 of the support column 6 rotating within the opening 5
This agitates the coins and prevents coins from clogging near the opening 5.

The coin that has moved onto the rotating disk 9 moves toward the outer circumference due to the centrifugal force caused by the rotation of the disk 9. After the outer edge of the coin is received by the guide plate 10,
The coin is placed on a rotating disk 9 along the inner wall surface of the guide plate 10.
It also moves toward the discharge side. During this coin movement, the protrusion 15 protruding laterally from the lower end of the support column 6 stirs the large number of coins supplied onto the rotating disk 9 so that they do not overlap, thereby preventing coins from clogging in the slit 12. Ru.

The coins 11 that have moved toward the discharge side along the inner wall surface of the guide plate 10 pass through the slits 12 one by one when they reach the bent portion 10a and are discharged to the outside of the guide plate 10. The ejected coin is urged by the rotating roller 21 and is paid out through the chute 22 to a receiving tray leading to the outside of the slot machine, etc. On the way from the roller 21 to the chute 22, the coin hits a sensor pin. 25 to rotate the lever 28, which is detected by the optical sensor 29. While the disk 9 is rotating, the coins 11 are sequentially paid out as described above, and each time the lever 28 is rotated to activate the optical sensor 29, and a pulse signal from the optical sensor 29 is output (not shown). The number of coins paid out is counted by being input to the control circuit. Then, when the predetermined number of coins is reached, the driving of the rotating disk 9 by the motor 7 is stopped, and the coin dispensing operation is completed.

Although the illustrated embodiment has been described above, the present invention is not limited thereto. For example, in the embodiment, the regulation plate disposed in the bucket is attached to a support provided upright on the rotary disk, but it is also possible to support the regulation plate by means other than the illustrated support. In addition, the protrusions that protrude laterally above the rotating disk may be placed inside the bottom opening of the bucket, and the positions of the posts and other members on which the protrusions are provided, as well as the protrusions, can be designed as desired, without being limited to those in the embodiments. can do.

[Effects of the Invention] As described above, the present invention includes a coin storage bucket having an opening formed at the bottom, a coin storage bucket arranged below the coin storage bucket so as to be rotated almost horizontally, and a coin storage bucket having a coin storage bucket formed with an opening at the bottom. A rotating disk that moves the coin outward by centrifugal force, a guide plate that guides the coin to the outlet while catching the outer edge of the coin that moves outward due to the rotation of this disk, and a coin in the bucket above the opening. In a coin dispensing device equipped with a regulating plate for receiving coins, since the bottom opening of the bucket is provided with a protrusion that protrudes horizontally above the rotating disk, coins are likely to be generated near the opening of the bucket. At the same time, it is possible to prevent coins from clogging at the payout port by making it difficult for coins moving together with the rotating disk to overlap.
