Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a coin sorting device, and particularly to a coin sorting device suitable for accurate and rapid sorting.

Conventionally, it is generally known that coins of mixed denominations are sorted by hand or by using a sorting machine. However, when it is done manually, it requires a lot of labor and time, and the reliability of the accuracy decreases over time.
When using a sorting machine, it is expensive and cannot be used easily, and conventional sorting machines cannot sort several denominations of coins at the same time, so the same coin has to be picked up by the sorting machine many times. There are some drawbacks, such as the need to hang the

The present invention was devised to solve these conventional difficulties, and its purpose is to provide a coin sorting device that can accurately and reliably sort coins of several denominations in one operation. There is something to do.

The present invention provides a table that rotates within an inclined base disk; a rotary plate that is located above the table and is provided with a number of outwardly opening notches on a peripheral edge that is guided by the base disk; A fixed plate that closes the notch from above, and a U-groove located above the fixed plate that rotates integrally with the rotary plate and whose outer side expands to both sides at a position corresponding to the notch. and a guide ring for guiding the falling of the coin, and a notch portion is provided at an inclined upper position of the fixed plate for causing the coin in the U groove to fall into the corresponding notch, and a base. Multiple types of slits with slit widths corresponding to the hardening diameter are provided at the lower inclined position of the disk, starting from the narrowest of the slits, and the table is rotated at a higher speed than the rotary plate to separate the coins in the notches. The coins are dropped separately into each slit and mixed coins of several denominations are simultaneously sorted.The present invention will be described below based on an illustrated embodiment.

In FIG. 1, reference numeral 1 denotes a two-tier bottom-shaped base disk disposed at an angle of approximately 50 degrees from the horizontal position, and an inner edge portion of the upper peripheral edge of the base disk 1 is arranged at an angle of approximately 50 degrees from the horizontal position. the first of
A guide ring 2 is provided that protrudes to a position above the bottom of the step, and a donut disk-shaped fixing plate 3 is fixed to the lower surface side of the protruding portion of the guide ring 2. On the other hand, a disk-shaped table 4 is disposed within the bottom of the second stage of the base disk 1, and this table 4 has a cylindrical rotation shaft 5a disposed around the rotation shaft 5 as shown in FIG. It is configured to be rotationally driven by.

The rotational force of the rotating shaft 5 is transmitted to the cylindrical rotating shaft 5a via a pulley or a belt (not shown), so that the cylindrical rotating shaft 5a rotates at a higher speed than the rotating shaft 5. In the bottom of the first stage of the base disk 1, as shown in FIG. A disc-shaped guide plate 7 having a thickness of 100 mm is arranged.

The rotating plate 6 and the guide plate 7 are attached to the rotating shaft 5 as shown in FIG. 1, and are configured to rotate at the same rotational speed. The fixed plate 3 is loosely fitted into the gap formed by the peripheral edge of the guide plate 7 and the thin part of the peripheral edge of the rotary plate 6. As shown in FIG. 2, a notch 8 is formed in the thin portion of the periphery of the rotating plate 6, and is large enough to accommodate a coin of the maximum diameter.
A large number of U-grooves 9 are provided at required intervals, and a large number of U-grooves 9 corresponding to the notches 8 are provided on the peripheral edge of the guide plate 7, as shown in FIG.

The front edge of the U-groove 92 in the direction of rotation of the guide plate widens outward. The coin inserted therein is configured to be prevented from falling out of the U-groove 9 by the guide ring 2. On the other hand, at the inclined upper position of the fixed plate 3, there is a 3
As shown, a notch 10 is provided so that the coin in the U-groove 9 can be dropped into the corresponding notch 8.

At the lower inclined position of the base disk 1, as shown in FIGS. 2 and 7A and 7B, slits 11 are formed by the number of types of coins, starting from the side with the smallest slit width, leaving the outer edge 1a slightly open. The slits 11 are provided one after another, and each slit 11 is configured to be able to sort and collect coins that have entered the notch 8 and are sent according to the coin diameter.

In addition, in FIGS. 3 to 7, Cl, C2, and C3 respectively indicate coins to be sorted.

When sorting in the above configuration, mixed coins of several denominations are thrown onto the square guide plate 7. Then, the coins are guided by the guide ring 2 and deposited on the inclined lower side of the guide plate 7. In this state, the rotating shaft 5 is
When rotated, the rotating plate 6 and the guide plate 7 rotate at the same rotational speed, and the table 4 is rotated by the rotation of the cylindrical rotating shaft 5a driven by the rotating shaft 5.

At this time, since the cylindrical rotation shaft 5a is configured to rotate at a higher speed than the rotation shaft 5, the table 4 rotates at a higher speed than the rotation plate 6 and the guide plate 7.

The coins Cl and C3 on the guide plate 7 enter the U-groove 9 and are sent upward on the slope, as shown in FIGS. 3A and 3B.

At this time, since the guide plate 7 is formed to have a thickness equivalent to one coin, the upper coin C2 is positioned on the upper surface side of the guide plate 7 as shown in FIG. It slides downward on the upper surface of the guide plate 1, and is surely fed one by one.

The coin C1 is prevented from falling out of the U groove 9 by the guide ring 2. The coin C1, which has been sent to the inclined upper end by the U groove 9 of the guide plate 7, is dropped by the notch 10 to the notch 8 side as shown in FIGS. 4A and 4B.

In the case of a large-diameter coin C2, it is similarly dropped to the notch 8 side, as shown by the chain line in FIG. As shown in FIG. 5, the coins Cl and C2 that have fallen into the notch 8 are regulated on the lower side by the base disk 1 and the table 4, and on the upper side by the fixing plate 3 (not shown). , and is sent to the downward side of the slope without falling off from the notch 8.

The coins Cl and C2 sent to the downward side of the slope are shown in Fig. 6A,
As shown in b, the centrifugal force accompanying the rotation of the table 4 and the speed difference between the rotating plate 6 and the table 4 cause the coins Cl and C to
2 is pressed against the base disk 1 side, that is, the outer edge,
In this state, it is sent further downward.

The coin sent to the slit 11 position is shown in Figure 7A.
, b, the outer end portion is placed on the upper surface side of the outer edge portion 1a of the base disk 1, and the inner end portion is placed on the upper surface side of the table 4 when passing over the slit 11.

However, the coin C1 with the smallest diameter has the first slit 11.
When the inner end reaches the table 4 as shown in FIG. 7a, it falls into the first slit 11 as shown in FIG. 7b.

On the other hand, the medium-sized coin C3 that passed through the first slit 11 falls into the second, slightly wider slit 11.
The large coin C2 is sent further downward.

In this way, the coins fall separately into the slits 11 having different slit widths for each denomination and are sorted.

Note that the rotational speeds of the rotating shaft 5 and the cylindrical rotating shaft 5a can be made faster than the other, or can be switched to the same speed, depending on the type of coin.

As is clear from the above description, according to the present invention, by rotating the table 4 at high speed, the coins in the notch 8 of the rotary plate 6 are pressed against the outer edge portion 1a of the base disk 11,
Since multiple types of slits 11 are formed between the outer circumferential surface of the table 4 and the outer edge 1a and have different slit widths in order from the narrowest of the slit widths, the mixed coins of several denominations can be mixed using the difference in diameter. The coins can be sorted by dropping them into the slit.

Furthermore, since the structure is simple, it is possible to plan for miniaturization of the device.

In the above embodiment, the rotary shaft 5 is driven by a prime mover, but it may be driven by human power such as hands or feet. A cover may be provided to cover the guide ring 2 to prevent coins from flying out from above the guide ring 2.

The present invention has been described above based on preferred embodiments, but according to the present invention, coins of several denominations can be sorted accurately and reliably in one operation.
