DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deposited coin separating mechanism provided in a coin processing machine such as a circulation type coin dispensing machine used in combination with a cash register or the like.

[0002]

2. Description of the Related Art As a circulation type coin depositing and dispensing machine described above, coins which are collectively inserted into a depositing port of a coin receiving section are separated one by one and conveyed to a coin discriminating apparatus at a later stage, where the authenticity of the coins is checked. After discrimination, coins are sorted by denomination at the coin discriminating unit, stored in the coin storage unit, and the number of coins corresponding to the withdrawal amount are paid out from the coin storage unit to the coin exit based on the withdrawal command. This is known, and the specific configuration is described in detail in JP-A-9-153160.

Next, the configuration of the above-mentioned circulation type coin receiving / dispensing machine will be described with reference to FIGS. 5 (a) and 5 (b). In the figure, 1
Is a body of a circulating coin depositing and dispensing machine, 2 is a coin receiving port provided on the front face thereof, 3 is a coin outlet, and a coin receiving section A, a coin discriminating section B, and a coin are provided inside the body 1. Coin sorting section C to sort by denomination, coins by denomination (1 yen, 5 yen,
Coin storage unit D, which is a storage tube 5 for storing the coins separately (10 yen, 50 yen, 100 yen, 500 yen), and coins from the storage tube 5 of the coin storage unit D to the coin payout exit 3 based on the dispensing command. A coin payout unit E to be paid out is arranged in a layout as shown in the figure.

[0004] Here, as a deposited coin separating and feeding mechanism of the coin receiving section A, a deposit carrying belt for carrying coins inserted at the bottom at the bottom of the coin depositing port 2 and carrying it toward the coin discriminating section B at the rear. (Endless belt) 6, and a reverse roller 7 for breaking up coins piled on the belt 6 and feeding out one by one. Note that the reverse roller 7 is driven by a drive motor 6 </ b> A with a belt being hung on a drive pulley of the deposit transfer belt 6.

[0005] Further, the belt transport type coin discriminating device 4 arranged in the coin discriminating section B includes a coin transport belt 4a, a coin discriminating sensor 4b, and a coin discriminating sensor, which are laid in a coin transport path in cooperation with the above-mentioned depositing transport belt 6. On the downstream side of the sensor 4b, there is provided a gate mechanism 4c for rejecting foreign coins other than currency and collecting them in the collection box 8. With such a configuration, when coins are put into the depositing port 2 in a lump, the coins are placed on the depositing conveyance belt 6 and aligned one by one and are fed out from the coin receiving section A to the coin discriminating section B at the subsequent stage. When the coin reaches the coin discriminating section B, the coin is transferred to the conveyor belt 4a.
And proceeds forward to check the size, material, thickness, and the like of the coin in the process of monetizing immediately below the discrimination sensor 4b, and determine the authenticity of the coin based on the data. Here, the coins determined to be "genuine coins" are conveyed as they are to the rear of the belt, and sent out from the terminal side to a coin sorting section C at the subsequent stage via a corner guide. On the other hand, the counterfeit coin is detected by the discrimination sensor 4b.
The coin determined to be is rejected laterally from the transport path by the operation of the gate mechanism 4c and discharged to the collection box 8. Then, the coin determined to be "genuine" is sent to the coin sorting section C, sorted by denomination, temporarily stored in the storage tube 5 of the coin storage section D by denomination, and then issued by a withdrawal command. The coins are paid out to the coin outlet 3 through the payout section E.

Next, the conventional structure of the deposited coin separating and dispensing mechanism provided in the coin receiving section A and the dispensing operation will be described with reference to FIGS. 6 (a) and 6 (b). That is, the deposit transfer belt 6 laid on the bottom side of the deposit opening 2 is stretched between the pulleys 6a and 6b, and the support provided on the lower side of the belt along the transfer path so that the transfer surface of the belt is not loosened. It is supported by the member 6c. On the other hand, the reverse roller 7 is disposed at the rear end outlet of the deposit port 2, and is supported at a fixed position so that a part of the peripheral surface of the roller protrudes into the deposit port. In addition,
The reverse roller 7 rotates in a direction opposite to the transport direction of the deposit transport belt 6. A gap H is set between the upper surface of the deposit transport belt 6 and the reverse roller 7 so that coins are cut out one by one and transported out. The largest coin of the currency is sized so that it can pass through the gap between the conveyor belt 6 and the reverse roller 7, and the thinnest coin can not be passed through at the same time with two or more coins overlapping.

Incidentally, coins of currencies currently circulating in Japan (1 yen, 5 yen, 10 yen, 50 yen, 100 yen, 500 yen)
Yen), the thickest coin is a 500 yen coin and the thickness is 1.8 mm, while the thinnest coin is a 1 yen coin and the thickness is 1.5 mm. Is set to 2.3 mm. With such a configuration, the deposit port 2
When a plurality of coins 13 are put in a lump at a time, the coins are stacked on the depositing conveyance belt 6 and conveyed in the direction of the arrow, but when they reach the position of the reverse roller 7, Lower coin 13 on it
a is passed through the gap H between the reverse roller 7 as it is and is conveyed to the coin discriminating section B (see FIG. 5) at a later stage, but the coin 13b overlapping on the upper side is However, it cannot be slipped through the gap H and, at the same time, is turned upright as shown by the reference numeral 13c by the rotational force of the reverse roller 7 to be inverted and returned inside the deposit port 2. As a result, the coins 13 which have been collectively inserted into the deposit port 2 are separated one by one, aligned on the deposit transport belt 6 and sent out toward the coin discriminating section B at the subsequent stage.

[0008]

However, in the above-described conventional structure for depositing and dispensing coins, the following problems remain in terms of functions. That is, in the conventional configuration, the gap H between the transport surface of the deposit transport belt 6 and the reverse roller 7 is fixedly defined. For this reason, if the thickness of the thickest 500-yen coin, such as the currency currently circulating in Japan, is less than twice the thickness of the thinnest 1-yen coin, the gap H is set as described above. 1 coin of each denomination
Although the coins can be separated and fed one by one, the situation is different when the coin depositing and dispensing machine is used in a foreign country or used for export.

That is, the thickness of coins of each denomination varies depending on the country of foreign currency. Therefore, if the difference between the thickness of the thickest coin and the thinnest coin among the denominations of the circulation currency is more than twice the thickness of the thin coin, the deposited coin separation and feeding mechanism of the conventional structure cannot cope with it, The gap H
Is set according to the thickest coin, the thinnest coin slips through the gap with the two coins overlapping, and the original separating and feeding function cannot be exhibited.

[0010] The present invention has been made in view of the above points, and for each denomination of the currency in circulation, there is almost no restriction on the difference in the thickness of the coins, and one coin of each denomination of a different thickness is used. It is an object of the present invention to provide a deposited coin separating and feeding mechanism of a coin processing machine improved so as to be able to reliably separate and feed.

[0011]

According to the present invention, there is provided, in accordance with the present invention, a deposited coin of a coin processing machine for separating and feeding out one coin at a time into a deposit port of a coin receiving section. A separating and feeding mechanism, comprising a deposit transport belt laid at the bottom of the deposit port, and a reverse roller disposed at the exit end of the deposit port facing the upper surface of the deposit transport belt, wherein the reverse roller is used for deposit transfer; The belt is movably supported in the vertical direction with respect to the belt surface, and a predetermined reference gap is set between the belt and the belt surface, and then the belt is biased toward the belt surface (claim 1). Specifically, it is configured in the following manner.

(1) A reverse roller is pivotally supported on a swing arm capable of swinging up and down, and a stopper for setting a reference gap and a biasing spring are provided on the swing arm. (2) Set the reference gap between the reverse roller and the deposit transport belt to Ho, and set d <Ho <2d, where d is the thickness of the thinnest coin among circulation currencies. .

(3) The coefficient of friction between the deposit transfer belt and the coin is μ1, the coefficient of friction between the reverse roller and the coin is μ2,
Assuming that the friction coefficient between coins is μ3, μ1>μ2> μ
The material of the receiving conveyor belt and the reverse roller is selected so as to be 3 (claim 4). According to the above configuration, among coins of each denomination having a different thickness,
Coins that are thinner than the reference gap Ho slip through the pay-in conveyor belt and the reverse roller one by one to be surely separated.
It is delivered. Coins thicker than the reference gap
When the paper passes through the reverse roller, the roller is pushed out and conveyed. When two or more coins are overlapped, the coins overlapping on the upper side are reversed by receiving the rotation force of the reverse roller and returned to the inside of the deposit port as in the operation of the conventional mechanism.

Therefore, even when the coin processing machine is brought into a foreign country and used, it is restricted by the thickness of the coin by setting the reference gap as described in the above item (2) in accordance with the coin of the circulation currency in that country. That is, coins of various denominations having various thicknesses can be surely separated one by one from a coin receiving portion and fed out and transported to a later coin discriminating portion or the like.

[0015]

FIG. 1 is a block diagram showing an embodiment of the present invention.
A description will be given based on the embodiments shown in FIGS. In the drawings of the embodiment, members corresponding to those in FIG. 5 are denoted by the same reference numerals, and detailed description thereof will be omitted. That is, in the illustrated embodiment, the reverse roller 7 is pivotally supported at the tip of a swing arm 8 that can swing up and down, and the base of the swing arm 9 is supported by a bearing 10. A gap setting stopper 11 is arranged below the swing arm 9, and the swing arm 9 is urged toward the stopper 11 by an urging spring 12 from above.

Here, the gap setting stopper 11 is constructed so as to be vertically movable by an adjusting mechanism (not shown), and when used, the gap between the deposit transfer belt 6 and the reverse roller 7 is described below. Initially, the reference gap Ho is set. That is, the aforementioned reference gap H
o is the coin of circulation currency handled by the coin depositing and dispensing machine,
Let d be the thickness of the thinnest coin of each denomination, d
<Ho <2d.

As for the materials of the deposit transfer belt 6 and the reverse roller 7, the deposit transfer belt 6 is made of a material having a large friction coefficient, and the reverse roller 7 is made of a material having a small friction coefficient, and is selected so as to satisfy the following conditions. . That is, the friction coefficient between the deposit transport belt 6 and the coin 13 is μ1, the friction coefficient between the reverse roller 7 and the coin 13 is μ2, and the coin 1
Assuming that the friction coefficient between the three is μ3, μ1>μ2> μ3
The material of the receiving conveyor belt and the reverse roller is determined so that

Next, the operation of the deposited coin separating and feeding mechanism configured as described above will be described. First, as shown in FIG. 2, a coin 13A thinner than the reference gap Ho passes through a gap between the deposit carrying belt 6 and the reverse roller 7 and is fed and conveyed from the deposit opening 2. When two coins 13A are overlapped as shown in FIG. 3, the coins overlapping on the upper side are separated from the lower coins by the reverse roller 7 and returned as described in FIG. Only coins are fed out and conveyed through the gap between the deposit conveyance belt 6 and the reverse roller 7. On the other hand, when the coin 13B thicker than the reference gap Ho reaches the position of the reverse roller 7 on the deposit carrying belt 6, as shown in FIG. As a result, the reverse roller 7 is pushed away to be fed and conveyed. Note that, in this case, the reverse roller 7
B will slip and rotate.

Therefore, as is apparent from the above description of operation, coins 13A and 13B of different denominations, which have been put into the deposit port 2 at a time, are separated from the deposit port 2 without fail. The coin can be transported to the coin discriminating section B (see FIG. 5) at the subsequent stage. In addition, by setting the reference gap Ho between the deposit transfer belt 6 and the reverse roller 7 in advance to d <Ho <2d where d is the thickness of the thinnest coin, coins of each denomination are distributed. Even if the difference between the thickest coin and the thin coin is more than twice, it can be easily handled.

[0020]

As described above, according to the structure of the present invention, among coins of different denominations having different thicknesses, coins thinner than the reference gap are placed one by one between the deposit transport belt and the reverse roller. When the coin passes through the reverse roller, it is pushed out of the roller, and is conveyed. Further, when two or more coins are overlapped, the coins overlapping on the upper side are returned to the inside of the deposit opening by receiving the rotational force of the reverse roller as in the operation of the conventional mechanism.

Therefore, even when the coin processing machine is brought into a foreign country and used, the thickness of the coin can be increased without being restricted by the thickness of the coin only by setting the reference gap in accordance with the coin thickness of the circulation currency in the country. It is possible to reliably separate coins of various denominations of different denominations one by one from a coin receiving unit and to feed out and transport them to a later-stage coin discriminating unit or the like.
