CONSTITUTION: The coin sending-out device 1 which guides coin moved outward by the rotation of a rotary disk 7 to a coin exit part 11 while receiving the coin, is provided with an exit guide plate 24, which guides the coin to the coin exit part 11 colliding against the coin guided by the coin guide plate 8, across a coin passage 9, and the exit guide plate 24 is formed out of an elastic member so that the guide plate winds and deforms when excessively loaded by the collision against the coin to pass the coin causing the load and then returns to its original position.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coin sending device which is incorporated in various vending machines, currency exchange machines, game machines typified by slot machines and the like to send out change and coins. In the present specification, the term “coin” is a concept that includes not only coins and coins, but also nominal coins such as tokens and medals, and the like.

[0002]

2. Description of the Related Art First Prior Art As a conventional coin feeding device, for example, one described in JP-A-62-46393 is known (in the present specification, "first prior art"). That).
This coin feeding device is provided on the coin guide plate while receiving the metal rotating disc that moves the coin outward by centrifugal force and the coin that is moved outward by the rotation of the rotating disc. It has an exit guide plate for guiding to the coin exit part.

Problem of the First Prior Art In this type of coin sending device, when the upper surface of the rotating disc is undulating or the driving device for rotating the rotating disc is played, the coin is rotated. When the disc rotates, it may shake vertically. For this reason, especially when the number of coins on the rotating disk becomes small, the coins may dance and may not be guided to the coin outlet. In addition, if a protrusion for stirring coins on the rotating disc or any other irregularities are provided in the coin guide plate, the coin may collide with them and the coin may dance in the same manner as described above. There is.

Second Prior Art On the other hand, the one disclosed in Japanese Utility Model Publication No. 35-12202 is also known. In this coin feeding device, a metal surface, that is, a coin passage is left on the outer periphery of a metallic rotating disc toward the center by a width substantially equal to the diameter of one processing coin, and a rubber plate is attached to the central portion thereof. It is a thing. The rubber plate is intended to apply frictional force to the coin on the rotating disc to stir the coin.

Problems of the Second Prior Art The metal surface provided on the outer periphery (coin passage) of the rotating disk is
It is presumed that the coin is then slid to accurately move the coin to the coin outlet, but if so, there was the following problem. That is, such a metal surface, that is, a sliding surface is necessary for the operation and effect, but as described above, it is not possible to stir the coins in the coin passage only by providing the rubber plate only in the central portion, so that the stirring efficiency is not always good. I can't say. This, in turn, can cause a decrease in the coin sending action.

Third Prior Art Further, as a forcible sending means for forcibly sending out a coin that has passed through a coin outlet by rotating, it is described in the above-mentioned first prior art and Japanese Utility Model Publication No. 63-80677. There is a disclosed discharge roller, and a coin delivery belt described in Japanese Patent Application Laid-Open No. 5-28340 filed by the present applicant. As means for driving this forced delivery means, in addition to the method disclosed in the former two cases, there is a method for obtaining transmission power from a friction roller frictionally transmitted by a rotating disc as disclosed in the last case. (Hereinafter referred to as "third prior art").

[0007] Problems of the third prior art, however, in the above-described driving means, the contact surface between the friction surface of the outer peripheral surface and the friction roller of the rotary disk (line) is narrow (short), both slip The transmission power cannot be extracted efficiently, and as a result, the delivery efficiency may be reduced.

[0008]

The problem to be solved by the present invention is to solve the above-mentioned problems.
Specifically, even if the coins on the rotating disc are dancing, they are surely guided to the coin outlet, and coins formed as a sliding surface as well as the central part on the rotating disc. To provide a coin delivery device with good delivery efficiency by applying frictional force to coins on a passage to improve agitation efficiency and effectively preventing slippage of a friction surface in the drive means of the forced delivery means. It is in.

Operation When the outlet guide plate is used The coins supplied in a loose state on the rotating disc are moved to the outer peripheral direction of the rotating disc, that is, outward by the centrifugal force generated by the rotation of the rotating disc. The moved coins are
While being received by the coin guide plate, the coin guide plate passes through the coin passage and is guided toward the coin outlet portion, and then collides with the outlet guide plate. The exit guide plate thus exposed to the collision of the coins normally guides the coins to the coin exit portion without curling and deforming. On the other hand, when the load caused by the collision of coins is excessive with respect to the hardness of the exit guide plate, that is, when the coins are in a lump state, the exit guides are used to allow them to pass without being guided to the coin exit part. The plate is rolled and deformed. Then, after passing the coin, the exit guide plate elastically returns to the original position.
On the other hand, when the load is not excessive, for example, when the load is due to the collision of one or two coins, these coins are guided in the direction of the coin outlet without being curled. This completes the payout of coins.

When the coin stirring friction surface is used, when the coin stirring friction surface including the portion extending to the coin passage rotates, the coin stirring friction surface is provided only in the central portion of the rotating disc. Compared with the case, it means that the coin passage is substantially expanded. As a result, a frictional force is applied not only to the coin in the center of the rotating plate but also to the coin in the coin passage. As a result, an efficient stirring effect can be obtained.

When the friction roller is provided with a V-shaped protrusion
When the rotary disc and the friction roller make frictional contact, the V-shaped groove provided on the whole person and the V-shaped protrusion provided on the latter contact each other, so that they contact each other as compared with the case where these are not provided. As the area increases, the V protrusions are pushed into the V grooves, and the contact is further strengthened by the so-called wedge effect. As a result,
Slip between the two is effectively prevented.
