Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a coin processing device for accumulating input coins and ejecting them one by one in public telephones, ticket vending machines, etc.

[Prior art]

For example, in public telephones, coins inserted through the coin slot of the telephone pass through the sorting section, as disclosed in the Research and Practical Application Report of Kokugo Public Corporation, Vol. 28, No. 11' (November 1979). A coin storage device is used in which the coins are passed through the storage unit and stored in the storage unit, and the coins are stored in the storage unit one by one from the storage unit under the control of a control unit that responds to a charge collection signal when the other party answers and each number of calls. .

In this coin storage device, the coin processing device used to accumulate coins and discharge them one at a time into the storage section is an electromagnet, as is clear from the fact that it is conventionally called a storage magnet. It is not only an extremely large number of parts, but also has a large volume, which poses an obstacle to miniaturization.

[Purpose of the invention]

The present invention aims to solve these drawbacks, and aims to provide a small-sized coin processing device with a small number of parts, a simple mechanism and a simple structure.

Another object of the present invention is to provide a coin handling device that requires significantly less power to operate.

[Structure of the invention]

The present invention provides a coin shooter having a coin flow path that guides coins and allows them to flow down sequentially, a rotary plate provided to rotate at a position away from the coin flow path of the coin shooter, and a rotary plate mounted on the rotary plate to rotate the coins. a plurality of protrusions provided at equal intervals around an axis and so as to sequentially protrude and retreat into gaps between adjacent coins in the coin flow path according to rotation of the rotary plate;
an engaging member that engages with the protrusion at a position out of the coin flow path; and a driving means for moving the engaging member between a position where it engages with the protrusion and a disengaged position. The coin processing device is characterized in that it is configured to allow the rotary plate to rotate intermittently one protrusion at a time by the operation of the drive means.

A piezoelectric bimorph can be used as the drive device.

〔Example〕

Hereinafter, two embodiments of the present invention will be described with reference to the drawings.

Referring to Figures 1 and 2, l is a coin.

Reference numeral 2 denotes a shooter having an inclined coin flow path 3, and coins 1 sequentially flow down the coin flow path 3 from the right end in the figure while rolling in an upright state. Reference numeral 4 denotes a rotary plate, which is fixed to the coin channel seat 6 of the seat holder 2 so as to be freely rotatable via a shaft 5. The thickness of the rotating plate 4 is set to be approximately the same as or slightly smaller than the thickness of the coin.

A plurality of recesses (notches) approximately the same as the outer circumference of a coin are provided on the outer periphery of the rotary plate 4, and the overall shape has a cross or star shape with a plurality of protrusions (4a to 4d). The protrusions 43 to 4d alternately and sequentially protrude and retreat into the coin flow path 3 by one rotation of the rotating plate.

6 is an arm that seesaws around axis 7 as a fulcrum.

At both ends, there are struts for alternately locking the rotary plate 4, and a base 6.
g, 6b are formed.

8 is a piezoelectric bimorph element, as shown in FIG.
It is made by joining two piezoelectric plates 9a and 8b, such as ZT, in a sandwich shape with a metal conductor plate 8c at the center, and its tip can be bent left and right depending on the applied voltage and polarity. This piezoelectric bimorph 8 is connected to the upper part of the arm 6, and its displacement causes the arm 6 to see-saw.

Due to this.

Since the stops 6 a r 6 b alternately engage with any of the protrusions 4 a to 4 d of the rotary plate 4, the two-turn plate 4 is allowed to rotate intermittently by the alternate movement of the stops 4-6 ae6 b.

To explain the operation with reference to FIGS. 4(a) and (b).

In the same (,) figure, a coin l is falling from the right side.

At this time, the piezoelectric bimorph 8 is bent toward the back side of the drawing, and the stop #6b of the arm 6 comes into contact with the protrusion 4b of the rotary plate 4, so that the rotary plate 4 does not rotate any further.

As a result, the coin 1a comes into contact with the protrusion 4a of the rotary plate and the ceiling of the chute, and is no longer able to advance to the left.

Next, by signal processing, a voltage of opposite polarity to the previous one is applied to the piezoelectric bimorph 8, and the piezoelectric bimorph is displaced in the opposite direction. As shown in the same figure (b), the stock A?
-5b is stopped 2 degrees in advance! -5a, the arm 6 seesaws so as to move toward the back side of the page. Step A-6b releases the locking of the protrusion 4b of the rotary plate 4. As a result, the one-turn plate 4 rotates due to the coin's own weight. On the other hand, the stop e-6a comes into contact with the protrusion 4d and stops rotating.

At this time, as shown in (b), the coin 1 is connected to the chute and the rotating plate 4.
It is locked between the protrusion 4a of.

Below, repeat these actions/#-5a.

By alternately displacing 6b and allowing intermittent rotation of the two-rotation plate 3, coins can be reliably ejected one by one.

〔Effect of the invention〕

As is clear from the above explanation, according to the present invention, the two mechanisms are simple, the number of parts is significantly less than that of the conventional electromagnetic system, and the space is also much smaller, and the structure is flat and flat. It is possible to Furthermore, by using a bimorph element, it is possible to save power by about 30%.
