Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a lightweight coin sorting device for sorting out lightweight pseudo coins that are lighter in weight than regular coins in coin processing devices such as public telephones and vending machines. It has a simple structure that can prevent unauthorized use.

[Conventional technology]

Generally, genuine coins and pseudo coins such as iron pieces or non-standard coins (hereinafter collectively referred to as pseudo coins) are sorted based on selection requirements such as weight, outer diameter, material, or magnetism. For sorting out light coins, for example, as shown in Japanese Utility Model Publication No. 58-40446, a coin sorting lever that is rotatably arranged and has one end protruding into the coin passage is used. The colliding coins are sorted and sorted depending on the presence or absence (size) of repulsive force of the coins. To further explain this based on FIG. 6, it is rotatably supported by a support shaft 2 installed on the base plate 1, and one end thereof is inserted into the coin passage 4 so that passing coins C collide with it. A coin sorting lever 5 that protrudes and has a suction piece 3 fixed to the other end, and a suction piece 3
The coin sorting lever 5 includes a permanent magnet 6 attached to the substrate 1 so as to face the coin sorting lever 5, and a stopper 7 for restricting rotation of the coin sorting lever 5. The coin sorting lever 5 is given a repulsive force in a counterclockwise direction around the support shaft 2 by the attractive force of the permanent magnet 6, and in the normal state, it comes into contact with the stopper 7 and is locked at the initial position as shown in the figure. , the magnitude of the counterclockwise repulsive force of the coin sorting lever 5 due to the attractive force of the permanent magnet 6 is:
When a coin C that rolls on the rail plate 8 and collides with the coin sorting lever 5 has a normal weight, the coin sorting lever 5 is pushed away by the kinetic energy of the coin C as shown by the chain line, and therefore the coin C can enter the storage track 9 as a regular coin, but the size is adjusted so that if it is lighter than a regular coin, it will be repelled and thrown into the return track 10.

[Problem that the invention attempts to solve]

By the way, there is no particular problem with public telephones, vending machines, etc. if users use these devices in a prescribed manner, but with devices that can be easily moved, such as desk-top types, users may intentionally Alternatively, if the coin is used tilted in the front-back direction, the impact force of the coin on the coin sorting lever 5 will change, so the lever 5 will not operate correctly, and therefore even light coins will fall into the storage track 9 and become regular coins. However, there were cases where the documents were stored incorrectly, and unauthorized use could not be completely prevented.

Therefore, the present invention solves the above-mentioned problems, has a simple structure, and makes it impossible to sort and sort coins when the device itself is intentionally tilted, thereby preventing unauthorized use. The object is to provide a lightweight coin sorting device.

[Means for solving problems]

In order to achieve the above object, the lightweight coin sorting device according to the present invention sorts the coins into good and bad coins based on the presence or absence of repulsive force when the coin collides with the substrate or side plate forming the coin passage. A rotatable coin sorting lever and a posture control piece that normally allows rotation of the coin sorting lever are arranged, and the posture control piece is moved in both directions of the substrate or side plate and in a direction orthogonal to the surface direction. The attitude control piece is pivotally supported so as to be freely swingable, and the attitude control piece is integrally provided with a horizontal part that is shifted toward the board side from the coin sorting lever, and the coin rolling side end of this horizontal part is bent in the plate thickness direction. Usually, the plate is located outside the rotation locus of the bent portion provided at the other end of the sorting lever, and when the board is tilted in the coin rolling direction, it engages with the bent portion and rotates the coin sorting lever. A first engaging portion for preventing movement is provided, and the lower surface of the horizontal portion is connected to the other end of the coin sorting lever when the substrate is tilted toward the side plate side or on the side plate side in the coin rolling direction. This is a second engaging portion that comes into contact with the lever to prevent rotation of the lever.

[Effect]

In the present invention, when the main body of the device is tilted toward the side plate in the coin rolling direction or toward the side plate in the coin rolling direction, the posture control piece approaches the coin sorting lever and prevents its rotation. The lever therefore repels all coins that come into contact with it.

〔Example〕

Hereinafter, the present invention will be described in detail based on embodiments shown in the drawings.

FIG. 1 is a front view showing an embodiment of a lightweight coin sorting device according to the present invention, FIG. 2 is an enlarged sectional view taken along the line of FIG. 1, and FIG. 3 is an enlarged view taken along the arrow A in FIG. Components in the figure that are the same as those in FIG. 6 are designated by the same reference numerals. In these figures, a base plate 1 is erected substantially vertically, and side plates 20, which together with the base plate 1 form a coin passage 4, are arranged in parallel at a predetermined distance from each other on the surface of the base plate 1. The side plate 20 has a flapper function by being rotatably supported at its upper end in a direction perpendicular to the surface thereof, that is, in a direction toward and away from the substrate 1.

The coin sorting lever 5 is rotatable (swinging) in the plane direction of the substrate 1 (horizontal direction in FIG. 1) by being pivotally supported at its vertically intermediate portion by a support shaft 2 implanted on the surface of the substrate 1. The lower end portion 5a protrudes into the coin passage 4 and closes the upper end opening of the normal accumulation track 9, and the upper end is integrally formed with a bent portion 5b bent in the direction of the side plate 20. At the same time, a suction piece 3 bent in a substantially inverted L-shape is fixed to the side opposite to the bending part 5b side. A permanent magnet 6, which is disposed on the substrate 1 opposite to the suction piece 3 and applies a repulsive force in the clockwise direction in FIG. It is formed on the side surface of the cylinder so as to be opposed to its central axis. Since such a permanent magnet 6 is disclosed in detail in Japanese Utility Model Publication No. 58-40446, its explanation will be omitted here.

A partition wall 22 is provided on the surface of the base plate 1 between the right end of the side plate 20 and the coin sorting lever 5, and a long hole 23 through which coins can pass is formed vertically at the base of this partition wall 22, and a cover 24 which covers the return track 10 together with the base plate 1 is attached to the tip surface of the lower end thereof.

A posture control piece 30, which constitutes the gist of the present invention, is disposed above the coin selection lever 5. The attitude control piece 30 is formed to have a general shape when viewed from the front, and its upper end is rotatably supported in the surface direction of the substrate 1 by a shaft 31 fixed to the surface of the substrate 1 by a set screw 32. There is. In this case, as shown in FIGS. 2 and 3, the shaft 31 includes a flange-shaped head 31A, a cylindrical portion 31B following the flange-shaped head 31A, and a conical portion 31C that widens toward the end following the cylindrical portion 31B. By integrally having the attitude control piece 30 between the inner surface of the brim-shaped head 31A and the large diameter end of the conical part 31C, the attitude control piece 30 can be rotated in the front-rear direction. That is, rocking in the direction toward and away from the substrate 1 is allowed. The attitude control piece 30
integrally has a protrusion 33 provided at the center of its upper end that protrudes toward the surface side, and when this protrusion 33 comes into contact with the back surface of the brim-shaped head 31A, the columnar part 31B and the conical part 31C, and is given the habit of moving in a direction away from the substrate 1 by the conical portion 31C. Moreover, the protrusion 3
When the substrate 1 is tilted toward the front side (side plate side) due to the presence of the protrusion 33, the posture control piece 30 rotates in a direction perpendicular to the surface of the substrate 1 using the protrusion 33 as a fulcrum, and the lower end thereof and the The distance from the substrate 1 increases as shown in FIG.

At the tip of a horizontal portion 30a that is integrally provided on the attitude control piece 30 and extends in the direction of the partition wall 22, a first engaging portion 34A that is bent forward at a substantially right angle is provided so that the coin sorting lever 5 can be folded. A balancer 35 is provided corresponding to the curved portion 5b, and is also integrally provided on the right side edge of the control piece 30, which is bent forward at a substantially right angle. The first engaging portion 34A is normally located above the coin sorting lever 5 and on the coin passage 4 side, and furthermore, is located outside the rotation locus of the bent portion 5b of the lever 5. Moreover, the attitude control piece 30
is normally positioned behind the coin sorting lever 5, that is, shifted by Δd (FIG. 2) toward the board 1, thereby allowing the lever 5 to rotate, and the board 1 is tilted toward the front side. As shown in FIG. 5, the lower end of the control piece 30 is close to the upper surface of the bent portion 5b, and constitutes a second engaging portion 34B that prevents the coin sorting lever 5 from rotating. . Note that the upper end portion of the partition wall 22 is brought into contact with or approached by the engaging portion 34, so that the upper end portion of the partition wall 22
It has a function as a stopper that prevents rotation in the clockwise direction in the figure.

In such a configuration, the attitude control piece 30
The operation and effects of this will be explained.

In the normal state shown in FIGS. 1 and 2, even if the coin sorting lever 5 rotates, the first engaging portion 34A or the second engaging portion 3 of the posture control piece 30
The lever 5 is not prevented from rotating by coming into contact with the lever 4B, so that the coin sorting operation by the lever 5 is performed in the same manner as in the conventional structure described above.

Next, when the main body of the device is tilted to the right, that is, in the rolling direction of the coin, as shown in FIG. 4 for the purpose of unauthorized use, the attitude control piece 30 always tries to maintain a vertical state due to the action of the balancer 35. The first engaging portion 34A engages with the bent portion 5b of the coin sorting lever 5 from below to lock the lever 5. Therefore, the coins that roll on the rail plate 8 (FIG. 1) and collide with the coin sorting lever 5 are returned to the return track 10 by the lever 5, regardless of whether they are regular coins or lightweight pseudo coins.
It will be blown away and returned to the return slot. In addition,
It will be easily understood that since the coin sorting lever 5 is given a repulsive force by the permanent magnet 6, it does not rotate and remains stationary even when the main body of the device is tilted. .

On the other hand, when the main body of the device is tilted forward, the attitude control piece 30 rotates in the direction away from the board 1 using the protrusion 33 as a rotation fulcrum, as shown in FIG.
The engaging portion 34B is the bent portion 5b of the coin sorting lever 5.
and moves above the suction piece 3. In this state, the distance between the members 5 and 30 is very small, and the second engaging portion 34B is located within the rotation area of the bent portion 5b. Therefore, even if the coin sorting lever 5 is hit by a coin, the bending portion 5b comes into contact with the second engaging portion 34B, so that the coin sorting lever 5 is prevented from rotating. Therefore, even in this case, the coin sorting and sorting operation by the coin sorting lever 5 is not performed, and all coins inserted from the input slot are returned to the return slot from the return track. In addition, when the main body of the device is tilted forward and at the same time tilted in the coin rolling direction, the first and second engaging portions 34A and 34B prevent the coin sorting lever 5 from rotating and sort and distribute the coins. make it inoperable.

Therefore, unauthorized use of lightweight pseudo coins can be reliably prevented.

[Effect of idea]

As explained above, the lightweight coin sorting device according to the present invention allows the coin sorting and sorting operation by the coin sorting lever in normal use, and allows the device body to be placed in the rolling direction of the coins, on the side plate side, or on the side plate side. Since the configuration includes a posture control piece that rotates when the coin sorting lever is tilted in the rolling direction and prevents the coin sorting lever from rotating, the structure is simple, all input coins are returned to the return slot, and it is lightweight. It can reliably prevent fraudulent use of counterfeit coins, and is particularly effective when implemented in mobile public telephones, vending machines, etc. Furthermore, since the attitude control piece is simply attached, existing products can be easily improved.
