Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a coin dispensing device in a vending machine or the like.

(b) Prior art In general, coin processing such as coin dispensing in vending machines is performed by a block called a coin mechanism, and the coin mechanism is equipped with a coin pipe that stores coins in a stacked manner and is used to move a coin dispensing plate back and forth. It is designed to eject coins one by one.

There is a technique disclosed in Japanese Patent Publication No. 53-28237 as a mechanism in which a coin dispensing plate that slides from side to side is provided below a coin pipe, and coins in the pipe are disbursed downward one by one by the reciprocating movement of this plate. However, in recent years, as the number of coin types handled by the coin mechanism increases and relatively large coins such as 500 yen coins are used, even with this conventional technology, the coin pipe has to be placed near the end of the board 3. When viewed as a coin mechanism, the coin pipe approaches the end of the coin mechanism. This will be explained in more detail with reference to FIGS. 1 and 2.

Namely, 2 is a base plate having an opening 1, 3 is a coin pipe that stands above the opening 1 and stores coins in a stacked manner, and 5 is a coin pipe that is disposed below the base plate 2 and faces the opening 1. 7 is a coin dispensing plate provided with a hole 6 that substantially matches the opening 1. With this configuration, in the standby state, the hole 6 and the opening 1 are opposed to each other, and one coin is accommodated in the hole 6. When the coin dispensing plate 7 moves to the left and the hole 6 reaches the coin dispensing opening 4, one coin is discharged. However, like this, coin pipe 3
is placed closer to the outer frame 8 of the coin mechanism, the dimensions l of the left edge and right end of the hole 6 of the coin dispensing plate 7 are short, so when the coin dispensing plate 7 moves to the left, the coin dispensing plate The right end of the coin at the lower end in the coin pipe 3 comes off from the right end of the coin pipe 7, and this coin comes into contact with the bottom plate 5.

(c) Problems to be solved by the invention As mentioned above, when a coin comes into contact with the bottom plate 5, if a large number of coins are stored in the coin pipe 3, the coin dispensing plate 7 will not be able to return to the right due to the weight of the coins. If there are too many coins, or if there are few coins, the coins will rotate clockwise about the opening edge as a fulcrum ₀₁ , causing coins to become jammed in the coin pipe 3.

In view of the above points, the present invention is a coin dispensing device that can be expected to operate stably by preventing the second coin in the coin pipe 3 from coming into contact with the bottom plate 5 when the coin dispensing plate 7 moves for coin dispensing. It provides:

(d) Means for Solving the Problems The present invention includes a substrate having an opening, a coin pipe erected above the opening for storing coins in a stacked manner, and a coin pipe facing the substrate and having the coins stacked therein. a bottom plate having a coin dispensing port at a position offset from the opening; a coin dispensing plate having a hole that slides back and forth between the bottom plate and the base plate and substantially matches the opening; A hole in the plate, which is pivotally supported at an end of the coin dispensing plate and has a protrusion on the other end that is elongated in a direction substantially perpendicular to the direction of movement of the coin dispensing plate and fits into an engaging part provided on the base plate or the bottom plate. is located along the edge of the plate when the hole corresponds to the opening of the substrate, and is located away from the edge of the plate in the coin dispensing state where the hole of the plate corresponds to the coin dispensing opening. and an arm that moves together with the opening to a position supporting the lower surface of the coin at the lowest position of the opening.

(E) Function As the coin dispensing plate 7 moves to the coin dispensing position, the arm 10 enters below the coin pipe 3 and supports the lower surface of the lowest coin in the coin pipe 3. And coin dispensing plate 7
As the arm 10 returns, the plate 7 smoothly moves on the bottom surface of the lowest coin in the coin pipe 3.

(F) Embodiment An embodiment of the present invention will be described below with reference to FIGS. 3 and 4.

3 and 4 are perspective views showing the main parts of FIGS. 1 and 2, and the same members are given the same numbers.
According to the present invention, the base plate 2 is provided with an engaging portion 8 formed by a groove or notch elongated in a direction substantially perpendicular to the direction of movement of the coin dispensing plate 7, and an engaging portion 8 is provided at the end of the coin dispensing plate 7 on the opening 1 side. One end of an arm 10 is pivotally supported by a pivot 11.
Note that the engaging portion 8 may be located on the bottom plate 5. The other end of the arm 10 is provided with a protrusion 9 that fits into the engaging portion 8, and the arm 10 has a substantially “dog” shape with a bent portion, and the height dimension of the arm 10 is similar to that of a coin. The thickness is approximately equal to the thickness of the dispensing plate 7.

With such a configuration, when the coin dispensing plate 7 moves during coin dispensing, one end of the arm 10 moves and the other end moves away from the coin dispensing plate 7 by the protrusion 9 sliding on the engaging portion 8 to the state shown in FIG. becomes.
Therefore, the coins in the coin pipe 3 are held by the end of the coin dispensing plate 7 and the top surface of the arm 10, and do not come into contact with the bottom plate 5. Incidentally, when the coin dispensing plate 7 is moved, the protrusion 9 can easily slide on the engaging part 8 by the action of the bent part of the arm. When the coin is discharged from the coin dispensing port 4, the coin dispensing plate 7 returns to the standby state shown in FIG. 3 in which the open end of the arm 10 also comes into contact with the coin dispensing plate 7.

(g) Effect of the invention According to the invention detailed above, an arm is pivotally supported at the end of the coin dispensing plate, and the arm is configured to open as the coin dispensing plate moves. Subsequent coins are held by the end of the coin dispensing plate and the arm. Therefore, the coin dispensing plate does not require space to completely hold the second and subsequent coins when dispensing coins, so even if the coin pipe is placed near the outer frame of the coin mechanism, it is certain that there will be no coin jams or malfunctions. A coin dispensing device is provided.
