Description

[Detailed description of the invention] (a) Industrial application field This invention is applicable to coins installed in automatic transaction processing devices (automated deposit payment devices, automatic currency exchange machines, etc.) that handle coins, vending machines that use coins, etc. This invention relates to a passageway jam release device.

(b) Conventional technology Some coin paths from the coin slot of a vending machine to a coin validator and coin transport paths inside automatic transaction processing devices are curved from the horizontal direction to the vertical direction. . When coins are continuously conveyed through such a coin passage, there is a risk that a so-called jam occurs in which a plurality of coins overlap on the curved surface and the coins become jammed. Therefore, it is conceivable to provide a jam release device on the curved surface of the coin passage to promptly deal with jams.

FIG. 1 shows a structural diagram of a general jam release device. A coin passage 1, which has a curved surface relative to the coin surface through which coins pass, is provided with an openable and closable flat plate 2 facing the coin passage 1 in order to discharge jammed coins out of the passage when a jam occurs. The flat plate 2 is rotatably supported at its upper end, and is normally closed to a position defined by a push rod 4 disposed on the side of the flat plate due to the pressing force of the coil spring 3. At the top of the coin passage 1, a light emitting element 5 and a light receiving element 6 constituting a jam detection means are arranged facing each other. A coin validator is provided at the bottom of the coin passage 1 to determine the denomination of the inserted coin. In the above configuration, even if the passing coin temporarily blocks the light of the light emitting element 5 and the light receiving element 6 detects that the coin has passed, a jam occurs if the coin validator does not generate a detection signal after a certain period of time. has occurred. Therefore, when this jam occurs, the push rod 4 is moved to the right by a solenoid or the like, the flat plate 2 is opened, and the jammed coins 8a, 8b are ejected out of the passage.

(c) Problems to be Solved by the Invention However, in the conventional jam release device as described above, the jammed coin 8 is removed by opening the flat plate 2.
In some cases, the jam coin 8a may fall into the branching part of the passage as shown in FIG.
There were disadvantages in that the jam could not be completely released because the ends 8a and 8b overlapped and stopped, and the flat plate 2 could not be closed.

This idea was made in view of the above drawbacks,
To provide a jam release device for a coin passage capable of completely removing jammed coins.

(d) Means for solving the problem This invention provides a discharge door that can be opened and closed on the concave side wall of the coin passage, which is curved with respect to the coin surface, and a convex side facing the coin passage. One end of a leaf spring is rotatably fixed to a wall surface, a protrusion is provided on the other end of the leaf spring on the discharge door side, and this protrusion is brought into contact with the discharge door when closed. Features.

(e) Function The coin passage jam release device of this invention has an openable and closable discharge door formed on the concave side wall of the curved coin passage, and when a jam occurs, this door is opened and the jammed coins are discharged to the outside. . Further, a leaf spring is provided on the convex side wall surface. One end of this leaf spring is fixed to the convex side wall surface, and the other end is brought into contact with the discharge door with a passage space provided by a protrusion. This contact causes the leaf spring to bend along the convex side wall surface. Here, when the ejection door is opened to release the jam, the contact between the ejection door and the leaf spring is also released, and the leaf spring is restored by its elastic force and its free end (other end) is directed toward the concave side wall surface. Rotate to. This rotation cleans the entire coin passage and allows coins to be removed wherever they may be stuck.

(f) Embodiment FIG. 3 is a structural diagram of a coin passage jam releasing device which is an embodiment of this invention. This example is the first
The difference in configuration from the conventional jam release device shown in the figure is that when the flat plate 2 is closed, the flat plate 2
A plate spring 9 is provided in the curved passage, which is deflected along the curved surface of the coin passage 1 and elastically returns when the flat plate 2 is opened to forcibly discharge the jam coins out of the passage. The leaf spring 9 is a substantially rectangular plate as a whole, as shown in FIG. The upper end 9a is a portion fixed to the curved surface of the coin passage 1. On both sides of the lower part, protrusions 9b and 9c against which the flat plate 2 abuts are vertically bent to face each other. These protrusions 9b, 9c
The gap formed by the contact with the flat plate 2 is wide enough for a coin 8c that does not jam to pass through, as shown in FIG. A sensor hole 9a is bored near the upper end of the leaf spring 9 at a position that faces and matches the sensor hole 2a of the flat plate 2, as shown in FIG. 5, when the flat plate 2 is fixed to a curved surface and closed. .

In the above configuration, even if a jam occurs as shown in FIG. 6A, if the push rod 4 is moved to the right to open the flat plate 2 as shown in FIG. Since the leaf spring 9, which had been bent due to the contact, elastically returns to a straight line, the jam coins 8a, 8b can be forcibly ejected out of the passage.

The flat plate 2 corresponds to the discharge door of this invention.

(g) Effects of the invention As described above, according to this invention, a leaf spring is rotatably provided on the convex side wall of the coin passage, and this is bent by the ejection door to release the jam. When the discharge door is opened, the leaf spring elastically returns and rotates to clean the entire passage. This rotation has the advantage that stuck coins can be forcibly and completely ejected.
