[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to coins, medals, etc. (collectively referred to as "coins" in this specification) used in automatic vending machines, automatic payment machines, currency exchange machines, game machines and the like. The present invention relates to a coin escalator connected to a coin sending device for sending out one coin from inside, and a coin carrying duct for carrying coins such as a coin carrying line used for polishing, replenishing, collecting and counting coins.

[0002]

2. Description of the Related Art As a conventional coin sending device, for example, the one disclosed in Japanese Patent Publication No. 62-45588 is known. In this type of coin feeding device, a coin feeding disc is provided so as to rotate in a plane inclined with respect to the horizontal in a hopper that accommodates a large number of coins in a loose state. Then, a plurality of coin pockets are defined by a central circular base portion on the coin feed disc and a plurality of coin feed pieces protruding from the disc surface at positions circumferentially separated from the disc outer peripheral portion, With these, each pocket is configured to pick up a coin from the lower portion of the hopper and send it upward by the rotation of the coin feeding disc, and to send out one coin to one by the pushing force of the coin feeding piece via the coin outlet of the coin feeding device. .

This type of coin sending device is used by being incorporated in, for example, a money changing machine, a game machine or the like. At that time, it is attached to the bottom of the machine, that is, at a low position. Therefore, the coin escalator is used to convey the coin in the lower position upward. This coin escalator is connected to the coin outlet portion 5 of the coin sending device, as indicated by reference numeral 6 in FIG. Here, the coin in the hopper is pushed into the escalator 6 from the coin outlet 5 through the curved inlet 6a of the coin escalator 6 and rises. The coins thus raised are
Eventually, a coin payout opening (not shown) located above the coin escalator 6 and a coin transfer line 7 (see FIG. 10).
It is sent to.

[0006] Continuing to refer to FIG. 11, the above-described coin escalator 6 includes a front side plate 8 and a rear side plate 9, and spacers for separating the front side plate 8 and the rear side plate 9 at a predetermined distance corresponding to the thickness of the conveyed coin. A coin passage 11 defined by 10 and 10 is provided. The coin passage 11 is in a hermetically sealed state at least at both lateral ends thereof. For this reason, dust that does not have a place to escape, abrasives, and the like adhere to the inside of the coin passage 11 and irregular shaped coins and large-diameter coins are mixed in, which often causes inconvenience in the coin transport operation.

Further, the front side plate 8, the rear side plate 9 and the spacer 10 are generally fixed to each other by screws. Therefore, it is necessary to remove these screws and remove the side plates to open the coin passage 11 when cleaning the above-mentioned dust, when removing odd-shaped coins, or when collecting normal coins. is there. However, this work is not only troublesome, but it may be difficult to perform such work in the assembled state due to the limitation of the work space.

Therefore, in order to prevent such adhesion of dust, it has been proposed to provide a dust discharge hole (not shown) in a side plate or the like of the coin carrying duct. However, it has been empirically recognized that this method alone does not sufficiently remove dust, and the inconvenience of the work of clearing a jam of coins has not been eliminated yet.

On the other hand, the coin escalator 6 shown in FIG.
As described above, the coin inlet 5 has a curved inlet 6
When it is extended upward through d and is incorporated in a game machine, for example, its height may reach 2 m or more. Since the coin outlet portion 5 is provided so as to be inclined with respect to the vertical line, the coin escalator 6 is also connected in an inclined state. If the coin escalator 6 is used in a tilted state, in order to lift a coin to a certain height, a corresponding depth dimension, that is, a horizontal distance between the coin outlet 5 and the tip of the coin passage 11 is required. Become. Therefore, in order to reduce the depth dimension, the coin escalator 6 is provided with the curved portion 6c, and the coin escalator 6 is extended in the vertical direction, that is, from the lower end portion 6a inclined with respect to the vertical line through the curved portion 6c and as indicated by 6b. I am letting you.

When the curved portion 6c is provided to change the direction of the coin escalator 6 as described above, there are the following problems. For example, as shown in FIG. 12, when the radius of curvature of the curved portion 6c is made relatively large, no big problem occurs. That is, the distance between the front side plate 8 and the rear side plate 9 on the straight line portion 6a as well as the straight line portion 6b is set to 0.2 times the coin thickness.
If the amount is about 0.5 mm, the coin is not caught in the curved portion 6c. However, as a result, a large depth dimension D-1 for turning the coin escalator must be taken.

In order to reduce the depth dimension, the curved portion 6
c If the radius of curvature is reduced as indicated by D-2, the result of FIG.
The distance between the front side plate 8 and the rear side plate 9 in the curved portion 6c must be increased as indicated by d, as shown in FIG. Then, there occurs a problem that the preceding coin or the following coin is inserted into this interval d and the two coins are overlapped and caught.

As means for solving such a problem, the one shown in FIG. 14 has been proposed. This is to press the coin in the curved portion 6c against the side plate 9 by the leaf spring 12, thereby preventing another coin from entering the space d. However, with this method, the coin A shown in FIG.
Since it is pressed by the free end of the coin, it cannot be pressed down as much as the coin A. Therefore, if the spring pressure is increased in order to sufficiently press the coin B as well as the coin A, not only the burden for pushing the coin up from below is increased, but also the problem that the coin is easily scratched, However, there is a problem that the leaf spring force is easily reduced by using

Further, since the width of the coin passage of the coin transfer duct is limited according to the diameter of the coin to be transferred, a plurality of different diameter coins (for example, 100-yen coin and 500-yen coin) can be simultaneously processed. There is an inconvenience that it is not possible to pass the coins or use one escalator to handle coins of different types.

A belt conveyor system is adopted to simultaneously convey such coins of different diameters. In this system, coins are placed on a belt and transferred, and therefore the coin surface is transferred horizontally. There must be. Therefore, there is a problem in that a large installation space must be secured as compared with the duct system that can transfer coins vertically.

[0013]

SUMMARY OF THE INVENTION An object of the present invention is to reduce the adhesion of dust in the coin passage of the coin conveying duct, and to clean and deform the inside of the coin passage without removing the side plate of the coin conveying duct. Let's provide a coin transfer duct that enables coins to be removed or normal coins to be collected, allows the transfer direction of coins to be flexible, and is a combined type that supports different coin sizes and does not require a large installation space. It is what

[0018]

FIG. 1 shows a first embodiment of a coin carrying duct according to the present invention. In the illustrated example, the coin escalator 6 is provided with a rear side plate 9 so that coins pass along the rear side plate 9. Also, this rear side plate 9
2 and 3, the lower end portion 6a is inclined with respect to the horizontal, the upper portion 6b extends vertically, and the curved portion 6c located between these portions.

Then, the linear rollers 6a and 6b and the curved portion 6c are partially or entirely provided with a pair of left and right taper rollers 13 on both sides of the coin passage 11 at appropriate intervals in the longitudinal direction of the coin passage. Are spaced apart from each other. As shown in FIG. 3, the taper roller 13 is formed in a top shape having a downward taper surface 14, and its center hole 1
5, the central shaft 16 is penetrated, and the taper roller 13 is rotatably provided around one end of the central shaft 16.

Then, as shown in FIG. 4, the other end of the central shaft 16 is passed through a guide groove hole 17 formed in the rear plate 9,
A sliding shoe 18 is attached to the shaft end of the central shaft 16 so that the taper roller 13 can move in the width direction of the coin passage 11. As a result, a spring force acts on the sliding shoes 18 of the pair of left and right taper rollers 13 in a direction to draw them together by the coil spring 19, and the coin is pushed between the left and right taper rollers 13 against the spring force. The downward taper surface 14 causes the coin to be pressed against the rear plate 9, thereby preventing the coin from rising.

Further, the taper roller 13 is provided with a guide groove hole 17
Since the coin passage 11 can be moved in the width direction of the coin passage 11, the passage width of the coin passage 13 becomes wider or narrower depending on the diameter of the coin to be transferred. This allows
Inside the escalator 6, multiple types of coins with different diameters (for example, 1
It is possible to simultaneously pass through a coin of 00 yen and a coin of 500 yen), and one escalator can be used for a plurality of coins of different diameters.

On the other hand, in the case of the embodiment shown in FIG. 5, the taper roller 13 having the downward taper surface 14 similar to that of the above-mentioned embodiment is used, and the central shaft 16 is penetrated into the mounting hole 20 formed in the rear side plate 9. Then, the large diameter end 22 of the conical spiral spring 21 is applied to the back surface of the rear side plate 9 and is inserted between the spring receiving plate 23 attached to the free end of the central shaft 16 and the rear side plate 9. As a result, similarly to the case of the above-described embodiment, a spring force acts in a direction in which the sliding shoes 18 of the pair of left and right taper rollers 13 are attracted to each other by the coil spring 19, and the coin moves to the left and right against the spring force. By pushing the coins between the taper rollers 13, the coins are pushed against the rear plate 9 by the action of the downward tapered surface 14, thereby preventing the coins from floating.

Next, another embodiment according to the present invention will be described with reference to FIG.
It will be described based on. In this case, the end plate 25 is fixed to one side of the coin passage 11 on the rear plate 9 with a screw, and the end face of the end plate 25 on the coin passage 11 side is directed outward in the width direction of the rear plate 9. An inclined track surface 26 that tilts is provided. The inclined orbital surface 26 is configured so as to be able to contact the outer peripheral edge of the passing coin, similarly to the downward taper surface 14 of the taper roller 13 described above. This is to prevent the passing coins from falling off due to the interaction with the taper roller 13 described below.

On the other hand, on the other side of the coin passage 11 facing the end plate 25, at least one taper roller 13 is rotatably provided with respect to the rear plate 9, and passes between the end plate 25 and the taper roller 13. Each taper roller 13 is provided with a downward tapered surface 14 that can come into contact with the outer peripheral edge of the coin. Then, as shown in FIG. 8 or FIG. 9, the taper roller 13 is loaded by the coil spring 19 or the spiral spring 21, respectively, so that a pressing force is applied to the outer peripheral edge of the coin contacting the downward taper surface 14.

With the above-mentioned structure, the coin pushed in against the spring force is inclined by pushing the outer peripheral edge of the coin between the end plate 25 and the taper roller 13. By the action of the raceway surface 26 and the downward taper surface 14, it is pressed against the rear side plate 9, thereby preventing the coin from rising.

Further, as shown in FIG. 6 as a third embodiment, instead of the end plate 25 shown in the second embodiment (FIG. 7),
One side of the coin passage 11 may be covered with the coin drop prevention plate 30. The fall prevention plate 30 is screwed to the rear side plate 9 via the spacer 10 so as to prevent passage of coins in the coin passage 11 but prevent the coins from falling.

Although the above-described embodiment shows the coin carrying duct for lifting the coins thrown out by the coin throwing device from the lower position to the upper side, as shown in FIG. 10, another coin throwing means 29 is used. In addition to sending the discharged coin upward, for example, the direction of the coin is changed in the horizontal direction via the horizontal bending portion 27, and further the curve bending portion 28 bends the coin in the thickness direction to move the coin to another place. It can also be suitably used in a transfer line.
