Description

TECHNICAL FIELD The present invention relates to a coin mech coin sorting device mounted on an automatic vending machine, a ticket vending machine, or the like.

(Prior Art) In recent years, vending machines have become more widespread due to an increase in the price of products sold and the expansion of sales varieties.
There is an increasing demand for higher performance of coin sorters for high-value coins as well as lower prices.

Conventionally, this type of coin sorting apparatus will be described with reference to FIGS. 3 (a) and (b) and FIGS. 4 (a) and (b).

3 (a) and 3 (b) are a front view and an enlarged side cross-sectional view of a conventional coin sorting device. As shown in FIG. 3 (b), the coin sorting device is fixed with a slight forward inclination. Wall 1
As shown in FIG. 3 (a), the fixed wall 1 is rotatably supported by the hinge 2 at the right end portion thereof, and although not shown in the drawing,
The movable wall 3 always biased by the spring device so as to face the fixed wall 1 in parallel with each other, and the orbit 4 formed on the wall surface of the fixed wall 1 and inclined downward to the right are shown in FIG. A magnetic field which forms the coin passage 5 shown in b) and which is arranged inside the fixed wall 1 and the movable wall 3 in the vicinity of the end of the orbit 4 to electrically discriminate between true and false coins. In order to identify the sensor and the presence / absence of deformation of the highest-valued coin and the presence / absence of deformation from the outer diameter, a fixed gauge is formed on the fixed wall 1 in front of the magnetic sensor so as to form a fixed gauge between the sensor and the track 4. It is composed of a stop gauge projection 6 formed. The raceway surface 4a of the raceway 4 shown by the dimension line D in FIG. 3 (b)
The distance between the gauge surface 6a and the gauge surface 6a of the gauge protrusion 6 is set to the maximum allowable value of the outer diameter of the coin 7 having the highest price. Further, a bell crank-shaped return lever 9 having a cam roller 8 mounted at its tip is pivotally supported on an upper portion of the fixed wall 1 intermediate between the hinge 2 and the gauge projection 6, and further, the return lever 9 described above.
It rotates together with and the hook-shaped part 10a at the tip at the end of the rotation.
A protruding lever 10 that is inserted into the lower side of the gauge projection 6 is pivotally supported. Although not shown, the return lever 9 and the projecting lever 10 are urged counterclockwise by a spring device so that the cam roller 8 stands by at the highest position as shown in FIG. 3 (a). It is supposed to do. Further, the lower end of the hook-shaped portion 10a is arranged at a position ahead of which the highest amount of coins rolling on the track 4 does not come into contact.
Further, the return lever 9 and the movable wall 3 described above are interlocked by a cam device (not shown), and as the return lever 9 is pushed down, the movable wall 3 opens toward the front with the hinge 2 as the support shaft, and the third The front surface 4b of the track 4 and the movable wall 3 shown in FIG.
The gap between the inner wall surface 3a and the inner wall surface 3a of the coin 7 that is narrower than the thickness of the coin 7 extends beyond the outer diameter of the coin 7. At the same time, the hook-shaped portion 10a of the protruding lever 10 enters under the gauge protrusion 6 and the gauge protrusion 6
The coin 7 held between the track 4 and the track 4 is released.

Regarding the operation of the coin sorting device configured as described above, Figs. 3 (a) and (b) and Figs. 4 (a) and (b)
This will be described below.

The coins inserted from the coin slot (not shown) of the vending machine are guided by the chute (not shown) in the machine, and the third coin
Enter the coin passage 5 from the left end side of the coin sorting device shown in the figure,
The orbital surface 4a of the orbit 4 rolls due to gravity. False coins or deformed coins having a diameter larger than the maximum coin 7 are blocked by the gauge surface 6a of the gauge protrusion 6. For a fake coin or a deformed coin stopped by the gauge protrusion 6, the return lever 9 is pushed downward by operating a return knob (not shown) provided outside the vending machine, and is rotated clockwise. As shown in FIG. 4, the movable wall 3 is moved away from the fixed wall 1, and at the same time, the protruding lever 10 is rotated clockwise, so that the hook-shaped portion 10a is stopped by the gauge protrusion 6 or a fake coin or deformation. By releasing the coin, it drops into a return chute (not shown).

(Problems to be Solved by the Invention) However, in the above-described configuration, the protruding lever 10 is necessary to remove the false coin or the deformed coin blocked by the gauge protrusion 6, and therefore the return lever 9 including the protruding lever 10 is not necessary. There is a problem that the manufacturing cost is high due to the large number of constituent parts, the increase in the material cost, the part processing cost, and the assembly man-hour. Coin 7 forcibly released by the protruding lever 10
, The fixed wall 1 needs to be tilted forward. Further, when the coin on the raceway surface 4a falls while being inverted, if the movable wall 3 is not opened sufficiently, the upper end of the coin 7 Is leaning against the movable wall 3 and does not drop, so that it has to be opened larger than the outer diameter of the coin 7, and there is a problem that the coin sorting device becomes large.

The present invention solves the above-mentioned problems, and provides a coin sorting device having a small installation space.

(Means for Solving the Problem) In order to achieve this object, the coin passage in the coin sorting device of the present invention is provided with a fixed wall provided substantially vertically, and with the return lever of the return lever provided substantially parallel to the fixed wall. A movable wall that rotates about a hinge as a fulcrum by an operation, the movable wall having an orbit for inclining a coin to be inserted into the entrance and rolling the coin on the orbital surface; A protrusion that forms an opening through which only coins having a smaller diameter than the maximum coin can pass is provided between the fixed wall, and the fixed wall is opened downward near the protrusion so as to straddle the coin passage, An L-shaped release claw for holding the upper end of the coin stopped by the protrusion is provided.

(Operation) With this configuration, even if a fake coin or the like gets stuck between the raceway surface and the protrusion in the coin passage, when the movable wall is opened by operating the return lever, the upper end of the coin is gripped by the release claw. Since the lower end of the coin will be separated from the raceway surface as it is, the coin will drop by its own weight. That is,
If the movable wall is opened only for the thickness dimension of coins, the coins clogged in the coin passage can be dropped from the orbit, and the installation space of the coin sorting device can be reduced.

(Embodiment) An embodiment of the present invention will be described with reference to FIGS. 1 (a) and (b) and FIGS. 2 (a) and (b). The same components as those of the related art are designated by the same reference numerals and the description thereof will be omitted.

1 (a), (b) and 2 (a), (b)
[Fig. 3] is a front view and an enlarged side cross-sectional view of an essential part of a coin sorting device according to the present invention. 1 (a) and (b)
In this regard, the present embodiment is different from the conventional example shown in FIGS. 3 (a) and 3 (b) in that an L-shaped release claw 11 is provided on the vertically fixed wall 1 and the conventional fixed wall. 1 is that the track 4 and the gauge protrusion 6 provided on the first wall are formed on the inner wall surface 3a of the movable wall 3, and the protruding lever 10 is omitted. When a counterfeit coin, a deformed coin, or a foreign substance-attached coin is blocked by the gauge protrusion 6 in the coin passage 5, the return lever 9
Is pushed downward, the movable wall 3 is moved away from the fixed wall 1 with the hinge 2 as a pivot by a cam device (not shown). The L-shaped release claw 11 provided on the fixed wall 1 scrapes and removes the coin 7 on the raceway surface 4a.

Regarding the operation of the coin sorting device configured in this way,
This will be described with reference to FIGS. 1 (a) and (b) and FIGS. 2 (a) and (b).

The coins inserted from the coin slot (not shown) of the vending machine are guided by the chute (not shown) in the machine to
It enters the track 4 from the left end of the fixed wall 1 shown in the figure, and rolls on the track surface 4a by gravity. False coins or deformed coins having a diameter larger than the maximum amount of coins 7 are detected by the fixed gauge composed of the raceway surface 4a and the gauge surface 6a and blocked. For the blocked fake coin or deformed coin, the return lever 9 is pushed downward by operating a return knob (not shown) provided outside the vending machine, and at the same time,
The movable wall 3 moves away from the fixed wall 1. At the same time as the coin passage 5 expands, the L-shaped release claw 11 provided on the fixed wall 1 scrapes a false coin or a deformed coin from the raceway surface 4a to drop it into a return chute (not shown) and return it. To do.

(Effects of the Invention) As described above, according to the present invention, a coin inlet, and a coin passage through which a coin inserted into the inlet is guided,
The coin passage is provided on the side surface of the coin passage, and a magnetic sensor for identifying the authenticity of the coin is provided.
It is composed of a fixed wall that is provided substantially vertically and a movable wall that is provided substantially parallel to the fixed wall and that rotates by using the hinge as a fulcrum when the return lever is operated. And a track for rolling a coin inserted into the entrance on the track surface, and a projection for forming an opening between the track surface and allowing only a coin having a diameter smaller than the maximum coin to pass, and The fixed wall is provided with an L-shaped release claw that opens downward near the protrusion so as to straddle the coin passage and grips the upper end of the coin stopped by the protrusion, thereby faking coins, etc. Even if is stuck between the orbital surface and the protrusion in the coin passage, if the movable wall is opened by operating the return lever, the upper end of the coin will be held by the release claw and the lower end will be separated from the orbital surface. So hard It would fall under its own weight. That is, by opening the movable wall only for the thickness dimension of coins, the coins clogged in the coin passage can be dropped from the track, and the installation space of the coin sorting device can be reduced.

Also, since the moving stroke of the movable wall is small, the operation stroke of the return lever can be made small, and the operability of the return lever is improved.

Further, since the protruding lever that has been used conventionally can be omitted, the number of parts can be reduced and the cost of the device can be reduced.
