Description

[Detailed Description of the Invention] [Technical Field of the Invention] This invention relates to a coin sorting device that can reliably distinguish denominations.

[Technical background of the invention and its problems]

The following devices are known as devices closest to the coin sorting device according to this invention.

That is, as shown in FIG. 4, if a first passage a that communicates with the coin slot and is approximately equal to the diameter of a predetermined coin C is made into a second passage midway, it branches into a third passage d, and at that branch point there is a first passage a. A first sorting member f having a locking piece e expanding toward the passage a, and a protrusion g facing toward the side edge of the first passage a.
A second sorting member provided with a coin C is rotatably disposed, and a weight i, which is slightly lighter than a predetermined coin C, is fixed to the lower part of the first sorting member f.

Such sorting devices are generally used in large and small vending machines, and the conventional devices have the following drawbacks.

In other words, when used under normal conditions, no problem occurs, but when a small vending machine is tilted at an angle of 2 to 30 degrees or more toward the second passage, the second sorting member becomes active. For example, if a 5 yen coin with a slightly smaller diameter is used in a device that is designed to use a 100 FI coin, but the same result is obtained as using a 100 yen coin. There is.

To explain this in detail, when the sorting device is set to the normal position and a designated 100 yen coin is inserted into it, this coin will be placed in the first
It passes through the passage a and reaches the protrusion of the second sorting member.

Then, the second sorting member is slightly rotated to the right by the coin C, and the coin C is separated from the protrusion g and transferred to the first sorting member f.
It rotates to the right so as to be held by the expanded locking piece e and is guided to the second passage, and then leaves the locking piece e.

On the other hand, when a 5 yen coin with a diameter slightly smaller than a 100FE coin is inserted, it is not locked and held by the locking piece e of the first sorting member, and is restricted by the protrusion g of the second sorting member. Since the product falls directly from the first passage a to the third passage d without entering the second passage, there would be no problem if the vending machine, ie, the sorting device, was in a normal state.

However, when this is tilted as described above, the second sorting member is also tilted, so this second sorting member ceases to act and is subject to the action of the locking piece of the first sorting member f. In some cases, a 100 yen coin and a 5 yen coin may be treated as the same coin in this sorting device.

[Purpose of invention]

Therefore, in this invention, a third sorting member is rotatably arranged, which has a pressing piece that comes into contact with the protrusion of the second sorting member, and has a weight slightly lighter than the predetermined coin fixed to its lower end. In this state, if the first and second sorting members perform the conventional coin sorting action, and the coins are tilted so that the coins are guided to the second passage side, the pressing piece is moved from the second sorting member. The second sorting member is brought into contact with the protrusion to prevent the second sorting member from tilting toward the second passage so that the protrusion faces the first passage, thereby making it possible to reliably select a predetermined coin. It was developed for the purpose of providing a coin sorting device.

[Example of idea]

Now, one embodiment of the coin sorting device according to this invention will be described based on FIGS. 1 to 3. 1 is a coin input slot (
(not shown) and is formed vertically and has an inner diameter slightly larger than the diameter of a predetermined coin C, and this first passage 1 is connected to a second passage 2 and a second passage 2 in the middle thereof. It branches into 3 passages.

The second passage 2 and the third passage 3 are arranged in parallel in the vertical direction,
Moreover, the third passage 3 communicates vertically below the first passage 1.

4 expands toward the first passage 1 and holds a predetermined coin C;
It is a first sorting member having two locking pieces 5, 5', and this first sorting member 4 has a predetermined coin (sorted and second coin) at its lower end.
A weight 6, which is slightly lighter than the coin (coin to be guided to the aisle) C, is fixedly attached to the coin, and the entire coin is arranged so as to be freely rotatable.

As shown in the figure, the weight 6 is fixed and deviated from the pivot point of the first sorting member 4 in a direction opposite to the second passage 2 side.

The first sorting member 4 is adapted to receive a rotational force in a counterclockwise direction about its pivot point, so that its locking pieces 5, 5' always face the first passage 1 side. .

Of the two locking pieces 5, 5', the locking piece 5 located on the second passage 2 side is provided to protrude lower than the other locking pieces 5', and the locking piece 5 that is located on the second passage 2 side is provided to protrude lower than the other locking piece 5'. When the coin C is held by the pieces 5.5', the mass point of the coin C is located at the first sorting member 4.
It is arranged so that it is on the second passage 2 side from the pivot point.

When this state is reached, the first sorting member 4 is configured so that it can be rotated clockwise around its pivot point, and rotates clockwise against the weight of the weight 6. It is designed to rotate in the direction.

Reference numeral 7 denotes a second passage having a protrusion 8 facing toward the first passage 1 side.
This second sorting member 7 is a sorting member, and is formed in an inverted shape, and is pivotally supported at one point so as to be rotatable.

That is, the second sorting member 7 is formed in an inverted shape and is pivoted at one point so that a rotational force is applied in a counterclockwise direction around the pivot point as shown in the figure.

The projection 8 is formed by being bent as shown in the figure, so as to face the first passage 1 side.

This protrusion 8 is a member for preventing coins other than the predetermined coins C from entering the second passage 2 side when coins C are inserted.

Reference numeral 9 denotes a third sorting member having a pressing piece 10 to be brought into contact with the protrusion 8 of the second sorting member 7, and a weight 11 slightly lighter than a predetermined coin C fixed to the lower end of the pressing piece 10. The sorting member 9 is also pivotally supported at one point and is rotatably disposed.

That is, the third sorting member 9 is formed into the shape shown in the figure, has a pressing piece 10 integrally formed therein, has a weight 11 disposed below its pivot point, and has the third sorting member 9 pivoted. When supported, as shown in FIGS. 1 and 2, during normal use, the pressing piece 10 is in an upright state so that it does not come into contact with anything, and as shown in FIG. When it is tilted at an angle of 25 degrees or more, it rotates counterclockwise about the pivot point so that the pressing piece 10 comes into contact with the protrusion 8 of the second sorting member 7.

As mentioned above, the weight 11 is slightly lighter than the predetermined coin C, but this is when the weight 11 is tilted and when the predetermined coin C is inserted, the second sorting member 7 The weight is set so that it can be rotated clockwise, that is, vertically, around the support α.

These first, second and third sorting members 4, 7.9
are arranged collectively at the branch points of the eleventh second and third passages 1, 2.3, respectively.

That is, the first sorting member 4 has locking pieces 5, 5' protruding into the first passage 1, and rotates independently of the other sorting members 7, 9 in both normal and abnormal conditions. It is movable.

In addition, although the second sorting member 7 is designed to rotate independently of the other sorting members 9 during normal times, the pressing piece 10 of the third sorting member 9 rotates when there is an abnormality (when it is tilted). They are designed to touch each other.

In addition, in the drawing, 12 indicates the first, second and third sorting members 4, 7.
．． 13 is a support plate for arranging the first and second
and a substrate for forming the third passage 1.2.3.

The support plate 12 is pivotally supported so as to overlap with the base plate 13, and this is done in consideration of the possibility that the passages 1, 2.3 may become clogged with coins C.

Therefore, when this sorting device is operated in a normal state, the coin C inserted from the coin input port first passes through the first passage 1 and comes into contact with the protrusion 8 of the second sorting member 7. It flicks the sorting member 7 and reaches the locking pieces 5, 5' of the first sorting member 4 below it.

Then, the coin C is held by these locking pieces 5, 5' and rotates toward the lower locking piece 5. At this time, the coin C is rotated against the weight of the weight 6 of the first sorting member 4. It rotates.

), which leads to the second passage 2. The coins C that have reached the second passage 2 are stored in a storage case (not shown).

) will be guided in the direction. Therefore, when this sorting device is used in such a normal state, the third sorting member 9 has no effect.

However, this sorting device is moved 25 degrees to 3 degrees toward the second passage 2 side.
When the third sorting member 9 is operated at a tilt angle of 0 degrees or more, the third sorting member 9 is operated by a weight 1 disposed at its lower end.
1, the pressing piece 10 has no effect of pressing the protrusion 8 of the second sorting member 7, and the weight 11 always tends to reach the lowest position due to the law of universal gravitation.

), the protrusion 8 of the second sorting member 7 is pressed by the pressing piece 10 to
You will continue to face aisle 1.

Therefore, since the coins C passing through the first passage 1 are affected by the protrusion 8, the coins C which are not the designated coins C are sent to the second passage 1.
It is not guided to the passage 2 side and is subjected to the same effect as the normal sorting as described above.

[Effect of idea]

As mentioned above, according to the coin sorting device according to this invention, when the coin sorting device is used under normal conditions, it is possible to perform accurate sorting as before, and it is also possible to use the coin sorting device tilted (abuse). However, since the protrusion of the second sorting member is forced to face the first passage by the second sorting member, accurate sorting can be performed in this case as well.
Furthermore, coins with a diameter larger than the specified coin will not enter the first passage,
Also, even if a coin with a small diameter enters the first aisle, it will be placed in the second aisle.
Due to the protrusion of the sorting member, the pieces do not enter the second passage and fall directly into the third passage.In short, by providing the third sorting member, accurate sorting can be performed.
