Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sorted coin supply device with a significantly simplified configuration.

In a conventional coin sorting machine, various kinds of coins, D', etc., are thrown into the bow of FIG. E, and while passing through the coin sorting path, coins other than those to be sorted are dropped.

In this case, if a large number of coins are thrown onto the rotary plate at once, it will not be possible to smoothly feed the coins from the rotary plate to the coin sorting path E. At the same time, a conveyor device C for feeding coins is provided on the bottom surface of the hopper, and a coin amount detector is provided directly above the rotary plate, and the output signal of the coin detector is used to detect the amount of coins. The drive of the conveyor device is controlled so that the amount of coins placed on the rotary plate is equal to or less than a predetermined amount.

The problem is that some of the coins that are supplied from the hopper to the conveyor device and fall are standing at right angles to the rotating plate, so in order to topple the coins that are standing up, the inside surface of the sorting ring F that surrounds the rotating plate is A protrusion of a predetermined shape is provided on.

With the above configuration, coins 1), I)'・
... can be reliably sorted, but since it is necessary to install a conveyor device C between the hopper A and the rotary plate B, the upper part of the hopper [-1 position is raised and bags and packaging This makes it difficult to insert heavy coins in tubes, etc., and it is necessary to install the hopper at a position offset from the axis of rotation B' of the rotary plate in order to facilitate the work of clearing coins jammed in the rotary plate part. However, there is a drawback that the coin sorting machine as a whole becomes larger.

The coins still pass through the conveyor device C and reach the metal rotary plate B.
Because it falls directly onto the top, each time the conveyor device is operated, a considerable amount of noise is generated due to the impact of metal on metal, causing discomfort to workers, or in work spaces such as banks and offices where silence is required. It also has the disadvantage of not being usable.

The present invention provides a hopper directly above the rotary plate, and
The lower end of the control tube that is continuous with the hopper has continuity, and a predetermined gap is formed between the lower edge of the control tube and the rotating plate so that coins can be directly taken out from the hopper onto the rotating plate. The above-mentioned drawbacks have been solved and will be described in detail below with reference to the accompanying drawings showing embodiments.

FIG. 1 is a simplified vertical sectional view of a coin sorting machine equipped with a coin feeding device to be sorted according to the present invention, and shows a coin sorting device (1) which is the most important feature of the present invention, and a rotary plate. (2) and a coin sorting section (3).

The coin feeding device (1) to be sorted, which is the most important aspect of the present invention, is as follows:
A hopper (Ill) is fixed to the coin sorter body (4) so that the coin discharge port (lla) is located directly above the center of the rotary plate (2), and a protrusion provided on the upper surface of the center of the rotary plate (2). 021, and a friction 0 made of rubber, urethane resin, etc. provided on the upper surface of the rotary plate (2) surrounding the protrusion (121).
3), the upper end edge is provided so as to fit with the lower end edge of the coin discharge port (Ila), and the lower end edge is below the lower surface of the coin discharge port...□.

When the control cylinder +141 is positioned above the friction (13), the control cylinder +141 is provided to surround the control cylinder part, and its lower edge is at approximately the same height as the lower edge of the control cylinder (141). It is composed of a regulating body 05) provided so as to be.

The protrusion (12) has a cylindrical ItQII (12a) integrally erected at the center of the upper surface of the conical body, and a cylindrical shaft (+21)) vertically arranged at the center of the lower surface. The cylindrical llTl1l (12b) is inserted through the rotary plate (2) and the rotary shaft tzz of the rotary plate (2), so that the protrusion (12) can rotate N as one body with the rotary plate (2).

Further, the control tube t141 is formed of urethane resin or the like in a shape that gradually expands in the F direction, and the regulating body (
15) is formed into a ring groove (16) for holding it together, and further L
An elastic annular hook (17) extending outward is integrally formed on the edge [ ] so that the annular hook Oη can be pressed against the outer peripheral surface of the lower end of the hopper (11), thereby connecting the hopper (11) and the control cylinder. (
14), and even if the hopper (11) falls down after seeing the input coins, its flexibility ensures that the hopper (11) and the ifi control tube (14) are connected securely. It is possible to connect.

Note that the gap between the lower edge of the control side J cylinder (14) and the rotating plate (2) must be set to be larger than the thickness of the thickest coin among the coins to be sorted. If it is too thick, it will be uncomfortable to have a large number of coins stacked on top of one another and unloaded, so it is most preferable to set the thickness to about twice the thickness of the thickest coin. Then again,
In order to prevent coins from jamming, the inner diameter of the control cylinder is preferably about twice or more the largest diameter coin to be sorted.

Further, the regulating body (15) has an inner peripheral edge formed in the annular groove tlf.
It is composed of an annular body formed so as to be able to fit with the control tube 04. ) so that it is approximately at the same height as the lower end surface of the

In addition, 0!1 is a mounting arm whose one end is fixed to a predetermined position on the base outside the sorting ring, and the lower end of the port lt201 is inserted into the other end of the mounting arm 09) so as to be movable upward. By screwing the part into a predetermined position of the regulating body (151), and by loosely fitting the coil spring (101) to the bolt t20+ between the mounting arm (191 and the regulating body 05), the regulating body 05 is permanently attached. , is biased downward.

However, the rotary plate is a metal disc with a protrusion O2 integrally provided on the upper surface of the central part and a friction member (13i) surrounding the protrusion (12), and a cylindrical plate. The circle (22) provided inside the separation ring (21) is
It is a rotating shaft, and t23+ is a sorting ring O1lK, which is a small sorting ring that allows coins to pass through the coin passage one by one. The distance between the lower surface of the sub-dividing ring 123+ and the - upper surface of the +j1 rotating plate (2) gradually increases in the direction of the rotational force of the rotating plate (2).

The coin sorting section (3) includes a pair of sorting courses (3I) whose spacing is variable according to the diameter of the coins to be counted, and a feeding belt provided above the center of the pair of sorting courses (31). +32).

In addition, (33) is a guide fitting that guides the sorted Puya coins,
Chiri, Seal) is a storage bag that stores selected coins.

The operation of the coin sorting machine having the above configuration is as follows.

After changing the interval between the pair of sorting courses (3) according to the diameter of the coins to be counted, a prime mover (not shown) is driven to rotate the rotary plate (2), and the feed bell l-+321 This completes the preparation for coin sorting operation.

By putting a large number of coins to be sorted into the hopper 01) at the same time in this state, the coins can be sorted in the following manner.

The lowest coin in contact with the rotary plate (2) at the lower end of the control cylinder continuous with the hopper is subjected to one centrifugal force by the rotation of the rotary plate (2), and is directed toward the sorting ring t71). be slid. In addition, at this time, the coin is placed on the rotating plate (2
) and the control cylinder ring to slide one sheet at a time.

Then, the slide l-”I until it touches the separation ring (21)
, the coins rotate with the rotary plate (2) from 1 to
3) and the rotating plate (2), the coins are fed to a coin sorting section (3) formed by a pair of two sorting courses (3I).

Then, only the coins to be sorted are passed through a pair of sorting courses (3
1), the other coins pass through sorting course 131) 1:
Coins can be sorted by falling through the 1j gap.

In the above case, if the amount of coins sent out from the control tube 0ω is large, a large number of coins will be stacked between the regulating body 05) and the separating ring 05).

Therefore, a large number of stacked coins are controlled from the outside (iIq
ii) The coins are always sent out from the control cylinder (14) to the snow bank without pressing the cylinder (14) at all.

In addition, since a protrusion (12) is provided on the upper surface of the central part of the rotary plate (2), in any case, the coin will slide down from the protrusion (12) and be supported on the friction (13), and the rotary plate will (As the sword rotates, centrifugal force is applied to the separation ring Ω1)
slide towards.

At the same time, more coins than the number of coins to be delivered in the i'F capacity determined by the distance between the control tube (141 and the rotary plate (2)) will be sent outward at the same time.
If you try to use the flexible control tube (14)
The edge of the coin can be displaced outwardly and upwardly to clamp these coins, and after sliding the coin in the lowest position, the upper hard one can be slid.

Above, the lowermost surface of the annular body 7 is used as the regulating body (5).
Although an embodiment has been described in which the cylindrical ring (I8) is supported by a single pair, the linog L]8) may be omitted and the annular body may be made of urethane resin or the like.

Furthermore, the upper surface between the regulating body (151 and the sorting ring (2I) may not be open, but may be covered with a plate made of a predetermined material. In this case, the height of the stacking claws of coins is regulated and , there is no danger of coins flying out, and it is 14φ.

As described above, the present invention enables direct rotation of the
Since the coins to be sorted are supplied in this manner, the power consumption for the conveyor movement can be reduced, and the bulk of the coin sorting machine as a whole can be reduced. This has the unique effect of eliminating the inconvenience of one coin being sent out to the rotary plate preventing the next coin from being sent out.
