Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a coin dispensing device such as a coin changer used in a vending machine (hereinafter referred to as a vending machine), a ticket vending machine, or a currency exchange machine.

2. Description of the Related Art Conventionally, as shown in FIG. 4, a coin changer has a coin sorting device 1 which distinguishes coins into genuine coins, counterfeit coins, and denominations, and sorts coins into each denomination. A coin storage device 2 for storing up to a certain number of coins, and a coin storage device 2 for returning the denomination and number of coins corresponding to the amount of change from the coin storage device to a vending machine return slot (not shown) when change is required at the time of sale. The coin dispensing device 3 is basically composed of three devices, and the coin dispensing device has a structure as shown in FIGS. 5 to 7.

In FIG. 5, a coin dispensing plate 4 is formed with a guide wall 6 for slidingly guiding a slider 5 and a coin dispensing hole 7 through which coins taken out are dispelled when the slider 5 slides. The slider 5 is formed with a coin receiving hole 8 that is slightly larger than the diameter of the coin, and a connecting pin 10 that connects the slider 5 with the drive mechanism section 9 that slides it. It is slightly thinner. "I"
In the second configuration, the coin dispensing plate 4 needs to have a complicated shape easily and at a low cost.

Therefore, in molding using metal, such as die casting I molding, etc., the cost of removing firmness after molding and the cost of anti-corrosion treatment on the surface increases the cost, so resin molding is used.

FIG. 6 shows a cross section of the coin dispensing device shown in FIG. 5,
The slider 5, which is disposed on the upper surface of the coin dispensing play 1-4 and performs a reciprocating sliding motion, is shown in a standby position in the figure.

A coin 14 at the bottom of the coins 13 stacked and stored in the coin storage hole 12 of the coin storage part 11 falls and fits into the coin receiving hole 8 formed by the fifth slider. Coin 14 accommodated inside coin receiving hole 8
is supported by the sliding surface 15 on the upper surface of the coin dispensing plate 4, and a wall 16.17 is formed from the drive mechanism section 9, and the position of the end 18.19 of the wall I6.17 is From the top of 14, the second coin 20
within the thickness of Further, the coin dispensing hole 7 is located at a position offset from the dispensing position of the sliding end of the slider 5 that performs a sliding motion.

The operation of the coin dispensing device configured as described above will be described below.

FIG. 7 shows a state in which the slider 5 has been slid from the standby position shown in FIG. 6 toward the payout position as shown in the figure by the operation of the drive mechanism section 9, and the coin receiving hole 8 of the slider 5 is shown in FIG. The coin 14, which had been accommodated in the drive mechanism section 9, passes under the end surface 18.19 of the wall 16.17 formed in the drive mechanism section 9. At this time, the coin 20 on top of the coin 14 tries to slide at the same time due to friction, but is stopped by the end 19. On the other hand, as the slider 5 slides to the bottom dead center, which is the payout position, the outer periphery 21 of the coin 14 taken out by the slider 5 touches the payout hole end surface 22 of the coin payout hole 7 formed in the coin payout plate 4. By passing by, it will fall downwards as shown. The slider 5 that has removed the coin 14 is slid toward the standby position, which is the top dead center, by the drive mechanism section 9.
The machine returns to the standby position shown in FIG. 6 and waits for the next coin 20 to be dispensed.

Problems to be Solved by the Invention In such a conventional configuration, the sliding surface 15 on the upper surface of the resin coin dispensing plate 4 is designed to prevent all coins stacked and stored in the coin storage hole 12 of the coin storage section 11 from being stacked. When the slider 5 takes out the coin 14 at the bottom while supporting the weight, the metal coin 14 moves while rubbing against the resin sliding surface 15.
The surface of the coins becomes worn or scratched as the number of coins dispensed increases. Further, even if the coin 14 is not dislodged downward through the coin dispensing hole 7, the end face of the coin dispensing hole 7 is abraded or scratched due to the outer diameter of the coin 14.

Since the surface of the sliding surface 15 becomes uneven due to wear and scratches, the coin 14 that is taken out by the slider 5 and moved to the payout position may be damaged due to scratches, especially on the outer edge of the coin. If there are any unevenness, this coin 1
If the coin 4 gets caught on the sliding surface 15, the sliding movement of the slider 5 is locked, and even when the slider 5 is locked, the slider 5 is forced to slide, causing the coin 14 to be flipped. Even when the coins 14 are thrown or thrown away, the coins 14 get caught on the end face 22 of the payout hole, so there is a problem in that the coins 14 cannot be stably taken out and moved and thrown off. The present invention solves these problems, and eliminates problems such as coin dispensing jams caused by wear and scratches due to frequency of use on the sliding surface of the coin dispensing plate and the end face of the dispensing hole. The purpose is to do so.

Means for Solving the Problems and In order to achieve this object, the present invention provides a means for dispensing coins from a portion of the coin dispensing plate corresponding to the coin storage hole to a hole edge of the coin dispensing hole on the coin storage hole side. A metal plate is provided to cover the sliding surface.

Function: With this configuration, the sliding surface of the coin dispensing plate and the hole line of the coin dispensing hole in the example of the coin storage hole are covered with a metal plate, so it is possible to eliminate wear and scratches, thereby preventing coin dispensing jams, etc. The occurrence of these problems can also be eliminated.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to the drawings. Note that parts that are the same as those in the conventional example are numbered the same. In FIG. 1, 4A is a coin dispensing plate formed using a resin material, and when the slider 5 slides from the standby position and takes out the coins to the coin dispensing hole 7A, the top surface of the coin dispensing plate 4A slides. The surface 15A is
It is formed of a metal plate 23, which is shown as a single item by a two-dot chain line. This metal plate 23 is made of resin material (coin payout play) 4A
At the time of molding, they are integrated by insert molding. In this case, the guide wall 6Δ for guiding the sliding movement of the slider 5 is constructed by flowing resin from the back surface of the metal plate 23 to the front surface through a plurality of through holes 24 formed in the metal plate 23, unlike the conventional method. Similarly, it is integrally formed.

FIG. 2 shows a cross section of the coin dispensing device shown in FIG. 1.

A coin 14 at the bottom of the coins 13 stacked and stored in the coin storage hole 12 of the coin storage part 11 is fitted into a coin receiving hole 8 formed in the slider 5 in a standby state. In this state, the coin 14 is placed on the sliding surface 15 of the metal plate 23 placed on the upper surface of the coin dispensing plate 4A.
It is supported by A. Regarding the operation of the coin dispensing device configured as described below, when the slider 5 slides from the standby state shown in FIG. 2 to the dispensing position, which is the bottom dead center, as shown in FIG. , the outer periphery 21 of the coin 14 taken out by the slider 5 passes through the end surface 22 of the coin dispensing hole 22 of the metal plate 23 that constitutes a part of the coin dispensing hole 7A formed in the coin dispensing play) 4A, and as a result, as shown in FIG. As shown by the two-dot chain line (the coin 14 will fall downward. As described above, according to this embodiment, the coin dispensing play) 4Aj = surface sliding surface 15 and coin dispensing hole 7A By constructing the dispensing hole end face 22 of the metal plate 23 having a hardness equal to or higher than that of the coin 14, it is possible to eliminate wear and scratches.

Further, the metal plate 23 of the above embodiment has an L-shape, and by placing it on the two sides of the resin-molded coin dispensing plate 4AJ by insert 1-molding, the coins stored in the coin storage hole 12 can be stored in the coin storage hole 12. This increases the strength to support the weight of the entire coin dispensing play 1-4A, thereby increasing the number of coins stored in the coin storage hole 12.

Effects of the Invention As described above, according to the present invention, by configuring the coin sliding surface of the coin dispensing plate and the end face of the coin dispensing hole with a metal plate, generation on the surface of the sliding surface and the end face of the coin dispensing hole is prevented. This can prevent wear and damage that may occur. Therefore, problems such as coin dispensing jams due to coins getting caught on the sliding surface, etc. do not occur.
