Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an improvement in a coin sorting machine that sorts coins by utilizing differences in repulsive force due to different materials of the coins.

Conventional technology A coin sorting machine that sorts coins by using the difference in repulsive force due to the difference in coin materials was developed on March 7, 1971.
As described in "Vending Machine Technology from the Perspective of Patents" published by Japan, page 66, various types are known.

FIG. 3 shows a schematic configuration of the above-mentioned prior art. Inserted coins C1, C2, etc. are guided by a cradle 1 etc. into a coin passage R1 formed by an inclined bottom plate 2 and two side plates, and each coin is is deflector 3
Due to the difference in repulsive force when colliding with the coin path R
2. The coins are sorted and distributed to R3, and the genuine/false coins and types are sorted out. Generally coin passage R2,R
Only coins of the same type can be guided through each of the coin passages, but it would be desirable to use deflector 3 to guide coins with different diameters into the same coin passage to sort out other coins and counterfeit coins. I have a request.

For example, when guiding two coins with different diameters, 100 yen and 500 yen, to the same passage, and guiding other coins or counterfeit coins to another passage, in a conventional coin sorting machine as shown in Fig. 3, When the 100 yen coin C1 collides with the deflector 3 to be repelled and guided to the coin path R2, the 500 yen coin C2 will move along the slope formed by the bottom plate 2 of the coin path R1. As in the case, the bottom plate 2 is accelerated by gravity.
Despite being given the same initial velocity and ejection angle as the 100 yen coin C1 when leaving the edge, the coin has a larger diameter and the coin path R1 has an inclination. The position of the mass point is higher and to the right than in the case of the 100 yen coin C1, and as a result, even though the falling trajectory is similar to that of the 100 yen coin C1, the trajectory is the same as in the case of the 100 yen coin C1. It will be located above and to the right compared to . Therefore, when the 500 yen coin C2 collides with the deflector 3, the locus of the mass point of the 500 yen coin C2 is located higher and to the right than in the case of the 100 yen coin C1, and its diameter is also larger. Therefore, compared to the 100 yen coin C1, the coin collides with the deflector 3 at a much higher position. In this position, when the 500 yen coin C2 is repelled by the deflector 3, the large diameter
The outer circumference of the 500 yen coin C2 contacts the end of the bottom plate 2 of the coin passage R1 as shown in FIG. and 500 yen coins could not be guided into the same coin passage.

Therefore, if you try to increase the distance between the end of the 500 yen coin C2 and the deflector 3 to prevent contact between the end of the bottom plate 2 and the deflector 3, for example, the horizontal distance between the end of the bottom plate 2 and the deflector 3 is If the coin is made large, the coins separated from the end of the bottom plate 2 will fall into the coin passages R2 and R3 due to free fall before reaching the deflector 3, while the coins separated from the end of the bottom plate 2 and the deflector If the vertical distance between the deflector 3 and the deflector 3 is large, the coins separated from the end of the bottom plate 2 and greatly accelerated by gravity will collide strongly with the deflector 3, making it difficult to sort the coins by repulsive force. In addition, in any case, it requires a larger space than the conventional one, and it also increases the speed of the coins hitting the deflector 3, so the mechanical efficiency of the sorting machine is limited. This is not desirable as it results in a decrease in durability.

Problems to be Solved by the Invention Therefore, the purpose of the present invention is to solve the above-mentioned drawbacks of the prior art, to be able to guide two coins with different diameters to the same coin path using the same deflector, and to create a compact deflector. Our objective is to provide a coin sorting machine by FRECTER.

Means for Solving the Problems The present invention forms the downstream end of the bottom of the coin passage with a rocking piece, supports the upstream side of the rocking piece rotatably, and swings the rocking piece by the weight of the coin. The inclination of the coin passage is made steeper, and the coin passage is rotatably pivoted on the surface opposite to the coin passage of one of the side plates forming the coin passage, and is biased by a spring to allow the coin passage to pass through a hole provided in the side plate. A lever having a first protruding piece that protrudes into the coin passage and a second protruding piece that prevents the rocking piece from swinging is provided, the first protruding piece of the lever is a coin that rolls in the coin passage, Of the two coins with different diameters that are guided into the same predetermined coin path after being repelled by the deflector, the lever is rotated against the force of the spring by contacting only the larger coin, and the second protruding piece is oscillated. The above-mentioned problem was solved by configuring the movable piece to be prevented from swinging.

Function: When a small-diameter coin rolls down the coin path and falls, the first protruding piece of the lever does not detect the coin, and the second protruding piece of the lever protrudes and causes the swinging piece to swing. Since the rocking piece prevents movement, the rocking piece forms the downstream end of the bottom of the coin passage without rotating, and rolls on the coin passage and the rocking piece to swing along the coin passage. The small-diameter coins separated from the pieces collide with the deflector, are repelled, and are guided to a predetermined coin path.

On the other hand, when a large-diameter coin rolls down the coin path and falls, the first protruding piece of the lever comes into contact with the coin and rotates the lever against the force of the spring. The protruding piece is retracted, the rocking piece is no longer prevented from swinging, and the rocking piece becomes rotatable, and when a rolling large-diameter coin rides on the rocking piece, the rocking piece rotates due to the coin's own weight. It swings toward the opposite side of the coin passage around the upstream side of the freely pivotally supported swinging piece, and the inclination of the downstream end of the bottom surface of the coin passage increases. The large-diameter coin is detached along the slope of the swinging piece, that is, the downstream end of the bottom surface of the coin passage, collides with the deflector, rebounds, and is guided into the same coin passage as the small-diameter coin.

Embodiment FIG. 1 shows the configuration of an embodiment of the present invention, with the side plate removed for clarity of explanation. FIG. 2 is a cross-sectional view taken along the line A-A in FIG. 1, and the side plates 6 and 7 are shown in this figure. Reference numeral 1 denotes a cradle that guides inserted coins to a coin passage R1 formed by a bottom plate 2 and side plates 6 and 7. Pivot parts 8, 8 are provided on the surface of one side plate 7 forming the coin passage on the side opposite to the coin passage, and a lever 5 is rotatably connected to the pivot parts 8, 8 with a shaft 9.
is provided, and the lever 5 is supported by a spring 10.
As shown in FIG. 2, it is urged to rotate clockwise about the shaft 9. The lever 5 also has first, second, and third protruding pieces 5a, 5b, and 5c that protrude into the coin path R1 through holes 11, 12, and 13 provided in the side plate 7. Further, the downstream end of the bottom plate 2 forming the bottom surface of the coin passage R1 is formed by a swinging piece 4, and the swinging piece 4 is rotatably pivoted to the side plate 6 or 7 on the upstream side thereof. In the normal state, as shown in FIG. 1, the rotation is stopped and held by the stopper 14, and the top surface of the bottom plate 2 and the top surface 4' of the swing piece 4 are held on the same plane, and the bottom surface of the coin passage R1 It forms the downstream end of the Also, the second protruding piece 5 of the lever 5
b protrudes and engages with the lower part of the rocking piece 4, and prevents the rocking piece 4 from rotating clockwise in FIG. 1, that is, toward the side opposite to the coin passage. Further, the third protruding piece 5c of the lever 5 protrudes into the coin passage R1, and becomes the same bottom surface as the bottom surface of the coin passage R1 formed by the upper surface of the bottom plate 2 and the upper surface 4' of the swinging piece 4. It forms part of R1. Further, the first protruding piece 5a of the lever 5 protrudes into the coin passage R1 as shown in FIG. 2, and is tapered 5a' in the coin entry direction. The distance between the first protruding piece 5a and the upper surface of the bottom plate 2 is as shown in FIG.
2 (for example, 500 yen) and larger than the diameter of a small diameter coin C1 (for example, 100 yen). In addition, 3 is a deflector, and the deflector 3 guides coins with different diameters C1 and C2 to the coin path R2, and other counterfeit coins etc. to the coin path R.
This leads to 3.

Therefore, if a coin C1 with a small diameter is inserted now, the coin C1 is guided by the cradle 1 to the coin passage R1 and rolls on the bottom plate 2, the upper surface 4' of the swinging piece 4, and the third protruding piece 5c. However, since the diameter of the coin is small, the protruding piece 5a does not detect the coin, and in the process of the coin rolling, the oscillating piece 4
The small-diameter coin C1 that is maintained in the normal state as shown in the figure and rolled on the bottom plate 2, the swinging piece 4, and the third protruding piece 5c moves along the slope of the coin passage R1. It separates from the protruding piece 5c that is the downstream end, follows a falling trajectory as shown in FIG. 1, collides with the deflector 3, rebounds, and is guided into the coin path R2.

Next, when a large-diameter coin C2 is inserted, it is guided by the cradle 1 to the coin passage R1 in the same way as the small-diameter coin C1, and rolls on the bottom plate 2. 5, the first protruding piece 5
a, and rotate the lever 5 counterclockwise in FIG. 2 against the force of the spring 10.
b and 5c also retreat from the coin path R1, the engagement between the rocking piece 4 and the protruding piece 5b is released, the rocking piece 4 becomes rotatable, and the rolling coin C2 rides on the rocking piece 4. Then, the rocking piece 4 rotates clockwise around the shaft 4'' to reach the state shown by the broken line in FIG. 1, that is, the rocking piece 4 rotatably supported by the shaft 4''. It swings toward the opposite side of the coin passage with the upstream side as the center, and the inclination of the downstream end of the bottom of the coin passage becomes large. On the other hand, since the protruding piece 5c retracted from the coin passage R1 no longer forms the coin passage R1, the total length of the coin passage R1 becomes shorter than in the case of a small-diameter coin C1.

Therefore, when the large-diameter coin C2 leaves the coin passage R1, compared to the case where the small-diameter coin C1 leaves, the swinging piece 4 swings toward the side opposite to the coin passage R1, thereby causing a large amount of damage. A tilt occurs, and the rocking piece 4
Since the downstream end of the coin is displaced downward, the coin will be released at a lower position.Furthermore, as the total length of the coin path R1 is shortened, the length of the slope that accelerates the coin is reduced, and the horizontal direction when the coin is released is reduced. Since the velocity decreases by , the falling trajectory is located below and to the left of the falling trajectory of the small-diameter coin C1, as shown in FIG.

Therefore, although the large-diameter coin C2 has a large diameter, the collision position with the deflector 3 is approximately the same position as the small-diameter coin C1, as shown in FIG. (see figure).

Next, the repulsive action when the large-diameter coin C2 collides with the deflector 3 will be explained based on FIG. 4.

In FIG. 4, large-diameter coin C2 indicated by a broken line
indicates the collision position when using the conventional coin sorting machine, and the large diameter coin C2 shown by a solid line indicates the collision position when using the coin sorting machine of this embodiment.

When using a conventional coin sorter, the speed of the large diameter coin C2 when it collides with the slope of the deflector 3 at an angle of θ with the axis perpendicular to the slope of the deflector 3 is expressed by v. However, this velocity v is a velocity component parallel to the slope of the deflector 3 vX (=
v・sin θ) and a velocity component vy (=v・cos θ) perpendicular to the slope of the deflector 3. When the large-diameter coin C2 having such velocity components vx and vy collides with the slope of the deflector 3,
The only velocity component affected by the repulsion coefficient e that exists between the large-diameter coin C2 and the slope of the deflector 3 is the velocity component vy perpendicular to the slope of the deflector 3, which is perpendicular to the slope of the deflector 3 after the collision. The velocity component vy′ is as follows: vy′=e・vy=e・v・cosθ (1).

On the other hand, the velocity component vx parallel to the slope of the deflector 3 is not affected by the coefficient of repulsion e, so the velocity component vx' parallel to the slope of the deflector 3 after the collision is vx' = vx = v・sinθ...(2).

Therefore, the large diameter coin C2 is the deflector 3.
The speed of the rebound movement after colliding with the slope of
Velocity component vy′ perpendicular to the slope of deflector 3 after collision and deflector 3 after collision
The velocity that is the composite of the velocity component vx′ parallel to the slope of
v', and the angle θ' that this velocity v' forms with the axis perpendicular to the slope of the deflector 3 is: θ'=arctan(vx'/vy')=arctan(v・sinθ/(e・v・cosθ )) arctan(tanθ/e) ...(3)

The same applies when using the coin sorting machine of this embodiment, and the axis perpendicular to the slope of the deflector 3 and Θ
If the velocity of the large-diameter coin C2 when it collides with the slope of the deflector 3 at an angle of is V, then the velocity component Vx parallel to the slope of the deflector 3 is V.
sinΘ, the velocity component Vy perpendicular to the slope of the deflector 3 is decomposed into V cosΘ, and the velocity component Vy′ perpendicular to the slope of the deflector 3 after the collision is between the large diameter coin C2 and the slope of the deflector 3. Vy'=q・cosΘ... (1') Also, the velocity component Vx parallel to the slope of the deflector 3 is not affected by the coefficient of repulsion e, so collision The velocity component Vx' parallel to the slope of the deflector 3 afterward is Vx'=V·sinΘ (2').

Therefore, the large diameter coin C2 is the deflector 3.
The speed of the rebound movement after colliding with the slope of
Velocity component Vy′ perpendicular to the slope of deflector 3 after collision and deflector 3 after collision
The velocity that is the composite of the velocity component Vx′ parallel to the slope of
V', and the angle Θ' that this velocity V' forms with the axis perpendicular to the slope of the deflector 3 is: Θ' = arctan (V・sinΘ / (e・V・cosΘ)) = arctan (tanΘ/e) ...It is expressed as (3′).

As is clear from equations (3) and (3'), the velocities v' and V' in the rebound movement after the large-diameter coin C2 collides with the slope of the deflector 3 are perpendicular to the slope of the deflector 3. The angles θ' and Θ' with the axes are determined by the repulsion coefficient e that exists between the large-diameter coin C2 and the slope of the deflector 3, regardless of the collision speed of the large-diameter coin C2 or the kinetic energy generated by its motion. When the coin collides with the slope of the deflector 3, the angles θ and Θ formed with the axis perpendicular to the slope of the deflector 3
It is determined only by

As described above, in this embodiment, the large-diameter coin C2 moves along the large inclination caused by the swinging piece 4 swinging in the opposite direction to the coin path R.
1, so when the coin C2 collides with the slope of the deflector 3, the angle formed with the axis perpendicular to the slope of the deflector 3 becomes larger than that of the conventional coin C2. That is, in FIG. 4, Θ>θ (4) holds true. On the other hand, since the coefficient of repulsion e between the large-diameter coin C2 and the slope of the deflector 3 is a constant value, the large-diameter coin C2 collides with the slope of the deflector 3 under the condition of equation (4). Comparing the angles θ' and Θ' that the velocity in the subsequent repulsive motion forms with the axis perpendicular to the slope of the deflector 3 using equations (3) and (3'), Θ'> It is obvious that θ′ ...(5).

That is, in this embodiment, compared to the conventional one, the injection angle due to the repulsive action after the large-diameter coin C2 collides with the slope of the deflector 3 shifts counterclockwise, so that the locus of the repulsive action of the coin C2 changes. Also the first
It will draw a low trajectory as shown in the figure.

As described above, in this embodiment, although the large-diameter coin C2 has a large diameter, the collision position with the deflector 3 is approximately the same position as the small-diameter coin C1, as shown in FIG. In other words, the position is sufficiently lower than that of the conventional one (see Figure 3).
Furthermore, since the locus of the repulsive movement of the coin C2 also draws a low locus as shown in FIG. A protrusion 5c forming a
The small diameter coin C1 does not come into contact with the rocking piece 4
The coins are guided to the same coin path R2.

Note that the small-diameter coin C1 and the large-diameter coin C2 are not the same in the speed of departure from the coin path R1, the departure angle, the departure position, and the coefficient of repulsion with the deflector 3, so the collision position with the deflector 3 is the same. Even if the trajectory of the falling coin C2 and the locus of the rebounding motion are slightly different, the trajectory of the falling coin C2 and the trajectory of the rebounding motion of the coin C2 are as described above.
The coin is guided to the coin path R2 by changing the withdrawal angle, withdrawal position, etc. of the coin.

In this way, after the large-diameter coin has passed, the swinging piece 4 returns to the solid line position in Figure 1, and the lever 5
The spring 10 returns to the state shown in FIGS.
It returns to the state where it prevents rocking.

In addition, in the above embodiment, the third protruding piece 5
c is provided to form a part of the coin passage R1, and the length of the coin passage R1 is changed depending on the size of the diameter of the coin, and the horizontal minute speed when the coin is removed is adjusted. It is not necessary to provide the protruding piece 5c, and it is sufficient to simply increase the inclination of the coin passage R1 by the swinging action of the swinging piece 4 and change the coin release position downward. At this time, if the upper surface 4' of the swinging piece 4 is extended to form a part of the coin passage R1 instead of the protruding piece 5c, the swinging piece 4 should be reliably returned to the solid line position in FIG. It is desirable to install a balancer etc.

In addition, although the lever 5 was provided on one side plate,
The other side plate is also provided with a second lever having the same structure as the lever 5, and when a coin of a certain diameter or more rolls, the second lever rotates and locks the swinging piece 4. If the oscillating piece 4 is tilted, the inclination angle of the oscillating piece 4 will change in two steps according to the diameter of the coin, thereby making it easier for the deflector 3 to sort out coins. Passage R2,
R3 can be selected arbitrarily.

Effects of the invention The present invention changes the angle and position of coin release by changing the inclination of the downstream end of the coin passage depending on the size of the inserted coin.
Even large-diameter coins do not come into contact with the ends of the coin path, and two coins with different diameters can be guided into the same coin path using the same deflector.
