Description

[Detailed Description of the Invention] This invention mainly relates to a coin sorting device for automatically selling a fixed amount of water or city gas each time a substitute coin is inserted into an advance payment meter installed at each customer. .

In view of the fact that this type of substitute coin has a low production cost and is difficult to imitate, the object of the present invention is to realize a substitute coin and a sorting device therefor that meet the above requirements.

The embodiment of the substitute coin shown in FIGS. 1 and 2 is made of thermoplastic plastic filled with ferrite powder, which is formed by penetrating a plurality of through holes 2 into a circular substrate 1 made of a non-magnetic material so as to be integral with each other from both sides. The magnetized portions 3 have different polarities on the front and back sides, with one side 1!13-1 magnetized as the north pole and the other side 3-2 as the south pole, and both sides 3-1.3-2 are The thickness is different and the front and back sides are asymmetrical.

When this coin is used as a substitute coin and is inserted downward in the correct posture from the input port 4 of the embodiment of the sorting device shown in FIGS. It rolls in the passage 5, turns at right angles, and advances horizontally to a specific location 6.

At the specific location 6, there is a magnetic body 3 on both sides 3-1, 3-2, which can freely reciprocate between a blocking position that prevents the magnetic body 3 from falling and a passing position that allows it to fall, and is normally biased by its own weight to take the blocking position. The blocking claws γ-1 and 7-2 are provided, and the blocking claws γ-1°γ
-2, a durable magnet 8-1.8-2 is fixed to the part directly opposite each part 3-1.3-2 of the magnetized part 3 of the substitute coin 1 at a specific place 6, and these are made of magnetic material. Because it receives magnetic repulsion from both 111J3-1.3-2 of 3,
The blocking claws 7-1.7-2 are moved from the blocking position shown in the figure to the passing position in conjunction with the durable magnets 8-1.8-2, and the substitute coins are moved to the binocular stop claws 1-1. It passes through the gap γ-2, falls, and advances to the outlet 9.

Even if a regular substitute coin is tried to be inserted face down, it will be blocked by the insertion slot 4 due to the asymmetry of the magnetic body 3.

The same applies when either side 3-1 or 3-2 of the magnetic body 3 is treated.

On the other hand, if it is too thin, open the first outlet 1 in the middle of the curved guide 5.
Fall to 0.

When the magnetic force of the magnetic body 3 is weak, the blocking claws l-1 and γ-2 are not sufficiently removed, and the substitute coin remains blocked at a specific location 6, and when there is no magnetic force, it remains blocked in the same way. remain.

When the lever 11 moves clockwise in the figure in conjunction with the operation to be performed after inserting the coin, the substitute coin blocked by this \ will be removed from the second ejection port 1.
It is discharged from 2.

The protrusion 11-2 is for pushing out the fraudulent substitute coin left in this way to the left against the attractive force of the durable magnets 8-1 and 8-2.

Although not shown, this coin sorting device is installed in the quantitative supply device, and only when a substitute coin falls from the outlet 9, the coin sorting device is made to perform the required quantitative supply operation for subsequent operations. It is.

Another embodiment of the substitute coin shown in FIGS. 5 and 6 has the shape of a baseball home plate as a whole, and has a groove 13 in the input direction indicated by the arrow, so that the front and back sides are asymmetrical. Three durable magnets 3a, 3b on the non-magnetic plastic coin 14,
3c, and these are magnetized with appropriate polarity in the thickness direction.

When this is put in the correct posture from the input port 4 of the sorting device whose embodiment is shown in FIGS. 1 and 8, the three blocking claws 7a
, 7b, 7c have fixed durable magnets 8a, sb, respectively.
, 8c are the durable magnets 3a, 3 of the substitute coins.
b, 3c, and when the opposing magnetic poles have the same polarity and exert repulsive force on each other, each blocking claw γa, γb, 7c is connected to the corresponding durable magnet 8a, 8b,
It moves to the passing position in conjunction with 8c, and the substitute coin is transferred to the sending port 9.
to fall.

If the magnetism of even one of the durable magnets 3a, 3b, and 3c of the substitute coin is the same as that of the corresponding durable magnet 8a of the sorting device,
, 8b and 8c, the corresponding blocking pawl remains protruded to the blocking position, and the substitute coin is ejected from the left ejection port 10 in FIG. 1 and reaches the delivery port 9. Never.

As described above, in the coin sorting device of the present invention, a magnetized substitute coin is used as a regular substitute coin, and the magnetized substitute coin is asymmetrical plate-shaped and has one or more magnetized portions with different polarities on both sides at fixed positions. reciprocating between a guide path that guides the substitute coin to a specific location only when the substitute coin is inserted in a certain position, a blocking position that prevents the substitute coin from falling at the specific location, and a passing position that allows the substitute coin to fall; one or more blocking claws that are normally biased to assume a blocking position; and the magnetized portion that is fixed to the blocking claws and directly faces the magnetized portion of the substitute coin located at the specific location. A durable magnet receives a repulsive magnetic force from the magnet and moves its blocking claw toward the passing position, and is installed in another device. The specified action is performed only when the object falls from a certain place.

Therefore, substitute coins can be easily mass-produced and the cost can be lowered, and it is difficult for general consumers who use the above-mentioned equipment to imitate them, and the structure of the sorting equipment is simple, so it is possible to reduce the cost. The purpose is achieved.

This invention is particularly effective for advance payment meters.
