2. Description of the Related Art In a game arcade equipped with a large number of coin gaming machines such as slot machines, it is desirable to be able to automatically supply coins to gaming machines or coin lending machines that are short on coins.
For this reason, conventionally, a coin supply device combining a coin transport conveyor and a coin scraping member for dropping coins on the conveyor into a coin supply port of a game machine or a coin lending machine has been used. The coin dropped into the coin supply port is dropped and supplied into a coin storage section in a coin gaming machine or a coin lending machine via a coin supply passage.

[0003]

However, in the conventional coin feeding device, when coins are caught between the belt surface and the coin scraping member or when coins accumulate in the coin passage, the belt is rubbed by friction. There has been a disadvantage that troubles such as stoppage and breakage of the coin scraping member easily occur.

Further, in the conventional coin feeding device, coins conveyed in piles on the conveyor are scraped off as they are by the coin scraping member. In some cases, a coin may be jammed in the mouth, or a large gap may occur in the coin storage unit.

[0005] Therefore, a main object of the present invention is to propose a coin supply device and a coin supply method in which these troubles are less likely to occur and a smooth coin supply is possible.

[0006]

According to the present invention, there is provided a coin feeding apparatus which solves the above-mentioned problems, comprising: a coin transporting conveyor having a starting end above a coin feeding position; Means for reversing the conveying direction of the conveyor when supplying.

Another coin supply device of the present invention is provided with a start end above a coin supply position, a coin transfer conveyor having at least a start end of a transfer surface inclined downward, and a coin transfer position at the coin supply position. And a means for stopping the conveyor when feeding.

[0008] On the other hand, the coin supply method of the present invention is a method in which coins are transported by using a coin transport conveyor arranged so as to have a starting end above the coin supply position, and the coins are supplied to the coin supply position. Reversing the conveying direction of the conveyor, conveying the coins on the conveyor to the start end of the transfer surface, and supplying the coins from the start end of the transfer surface to the coin supply position.

Another coin feeding method according to the present invention transfers coins using a coin transfer conveyor which is disposed so as to have a starting end above a coin feeding position, and at least a starting end of a transfer surface is inclined downward. When supplying coins to the coin supply position, the conveyor is stopped, and coins on the inclined conveying surface of the conveyor are slid or rolled along the inclined conveying surface toward the starting end, and the starting end of the conveying surface is From the coin supply position.

<Operation> In the present invention, coins can be supplied to the coin supply position only by reversing or stopping the conveyer for conveying coins. The trouble that has occurred does not substantially occur.

The coin storage units H, H,... Of the coin gaming machines 2, 2 and the coin lending machines 3, 3, respectively, have the following storage amounts.
Based on the detection results of the upper and lower limit level sensors S1 and S2, the control means constantly or periodically monitors.

As a result of this monitoring, if the coin storage units H, H,... Of the coin gaming machines 2, 2 and the coin lending machines 3, 3 are smaller than the lower limit, and there is no need to supply coins, The control means controls each of the conveyor units 10, 10,..., The return conveyor 6, and the lifting device 7 so that the above-described island returning operation is continued. If necessary, for example, when coins are evenly distributed in the coin supply device 1, the island returning operation can be suspended.

On the other hand, the storage amount of any one of the coin storage units H, H... Or the plurality of coin storage units H, H. When the value is equal to or less than the lower limit, the control unit controls the corresponding rotation drive source 15 so as to reverse the transport band 14 of the conveyor unit 10 having the start end above the coin receiving slot R corresponding to the coin storage unit H. . by this,
As shown in FIG. 5 (b), the coins C, C,... On the transporting belt 14 of the conveyor unit 10 which is rotated in the reverse direction are transported to the opposite side to the island returning operation, that is, to the leading end of the transport surface. Fall supplied. Also, coins C, C,... Are sequentially dropped and supplied from the upstream conveyor unit 10 onto the transport belt 14 of the reversing conveyor unit 10 as in the island return operation, and the coins C, C. The conveyor unit 10 drops and supplies the coin to the coin receiving slot R.

If it is detected by the upper limit level sensor S1 that the coin storage unit H to be replenished has reached the upper limit due to such replenishment, the conveyor unit 10 that has been reversed is returned to the island return operation. ,
The control means controls the corresponding rotary drive source. When coins are supplied to the plurality of coin storage units H, H..., The operation may be returned to the island returning operation in order from the conveyor unit 10 corresponding to the coin storage unit H for which coin supply has been completed. For example, in the case where the coin overflow of the coin storage units H, H... Does not pose a problem (such as returning an overflow coin) as in this example, the replenishment operation is performed when the replenishment of the last coin storage unit H is completed. . May be returned to the island returning operation at the same time.

Here, instead of the upper limit level sensors S1, S1... In the above example, overflow sensors S3, S3... Are provided on the overflow paths F, F. Can be. In the above example, the upper limit level sensor S

A coin supply device 201B may be provided so as to perform supply. Also in this example, a drop return path 205 that receives the coins of the coin supply devices 201A and 201B and supplies the return to a return conveyor (not shown), and conveys the coins from the drop return path 205 to the coin lifting devices 207A and 207B. A return conveyor (not shown) for supplying coins is provided, and coins can be returned and supplied on one side and the other side in the longitudinal direction of the island. In the illustrated example, the coin supply device 201A,
A common drop return path 205 for returning coins from both of the coin supply devices 201A and 201B is provided.
It may be provided for each B.

(B) The coin supply device according to the present invention can also be applied to an island constituted by arranging coin supply target device rows in which coin supply target devices are arranged side by side back to back. In this case, a coin supply device can be provided for each of the coin supply target device rows so as to supply coins to the coin supply target devices from one end to the other end of the row. In the mode shown in FIG. 7A, the coin supply devices 211A and 211B disposed in each of the coin supply target device rows 210A and 210B convey coins in the same direction as indicated by arrows, and the coins in the corresponding row are displayed. Supply target device 21
The coins are supplied to the coins 2, 212..., And the coin drop return path 215, the return conveyor (not shown) and the lifting device 217 are commonly used. On the other hand, in the mode shown in FIG. 7B, the coin supply devices 211A and 211B provided in each of the coin supply target device rows 210A and 210B convey coins in opposite directions as indicated by arrows. , The coin supply target device 21 in the corresponding row
2, 212... Are provided with a coin return path 215 A, 215 B, a return conveyor (not shown), and a coin lifting apparatus 217 A, 217 B for each of the coin supply apparatuses 211 A, 211 B. .

(C) In the example shown in FIG. 8A as well, the coin supply device is disposed on an island constituted by arranging coin supply target device rows in which coin supply target devices are arranged side by side back to back. However, the coin supply target device rows 220A, 22
0B, coin supply devices 221A, 221
B and the coin supply device 221A in one row 220A and the coin supply device 22 in the other row 220B.
1B is connected at the end by a revolving conveyor 229, and the coin conveyed to the end by one coin supply device 221A is supplied by a revolving conveyor 229 to the beginning of the other coin supply device 221B. 22
Reference numerals 2,222... Indicate coin supply target devices. In this case, as shown in FIG. 8 (b), the coin supply device 221A in one row 220A and the coin supply device 221B in the other row 220B are also connected at the other end by the revolving conveyor 230, and one coin is provided. The coin conveyed to the end by the supply device 221A is transferred to the rotating conveyor 229.
Is supplied to the start end of the other coin supply device 221B, and the coin conveyed to the end by the other coin supply device 221B is again supplied to the start end of the one coin supply device 221A by the revolving conveyor 230. The coin can be circulated to supply coins to the coin supply target devices 222, 222,. For this circuit,
Coins are supplied as needed by a lifting device 227 provided at the end of the row (or in the middle in the longitudinal direction, between rows, etc.). As the rotating conveyor of this example, the one disclosed in Japanese Patent Publication No. 6-6195 by the present applicant can be applied.

In the above example, even when the coin return path 5 is not provided, for example, the conveyor unit 10 at the end is always reversed, and the coin is stored through the coin receiving port R and the supply path P corresponding thereto. By supplying the surplus coins to the section H and causing the surplus coins to overflow from the coin storage section H, the surplus coins of the coin supply device 1 can be supplied to the return conveyor 6. In this case, in addition to the end conveyor unit 10, the other conveyor units 10, 10,... Can also be reversed.

As described above, in the coin supply method of the present embodiment,
By controlling the rotation direction of the conveyor units 10, 10,..., Coins can be supplied to the coin replenishment target device, so that coins on the conveyor are scraped off by a coin scraping member, compared with the conventional method. Coins can be smoothly replenished for a long time without any trouble.

Although the coin supply method of the present embodiment was not predicted at first, as a result of repeated experiments, it was found that coins were clogged in the coin receiving holes R, R, and so on.
It has been found that it is possible to effectively prevent the generation of an excessive gap in the coin storing sections H, H. That is, in the above-described method, coins are transferred between the conveyor belts 10 and 10 from the transport belt 14 to the transport belt 14 by natural fall of the coins. Apparatus 1
, Conveyor belts 10, 1.
4: Upper coins are unlikely to be piled up. In particular, in the above example, since the coin falls on the inclined conveying surface, the degree of dispersal of the coin is large. Therefore, when the conveyor units 10, 10,... Are reversed in order to supply coins, the coins are supplied to the coin receiving holes R, R,. Therefore, in the coin supply method of the present example, there is almost no bridging effect between the coins, and coins may be jammed in the coin supply ports R, R, or large gaps may be generated in the coin storage sections H, H. It is prevented.

On the other hand, another coin supply method included in the present invention will be described below. It should be noted that these coin supply methods can be applied to the above-described gaming facilities. <Another Example 1> FIG. 9 shows the start end 22a above the coin supply position.
Conveyor 22 having a

2, a transport surface 22b from at least the portion where the coin C is supplied from the first conveyor 21 to the start end 22a is inclined downward toward the start end, and the other end 22c side portion is horizontal. is there.

In this embodiment, when the coin C is not supplied to the coin supply position, as shown in FIG.
The conveyor 22 is driven in the direction of the arrow to convey the coin C dropped and supplied from the first conveyor 21 from the start end 22a to the end 22c. The coin C conveyed to the terminal side can be recycled by returning it to the first conveyor 21 by a returning device (not shown). On the other hand, when the coin C is supplied to the coin supply position, as shown in FIG. 9B, the second conveyor 22 is stopped or rotated in reverse while the first conveyor 21 is driven (in the opposite direction to the coin conveyance direction). ). Thereby, the coin C supplied from the first conveyor 21 is transferred to the inclined conveying surface 2 of the second conveyor 22.
It moves downward along 2b, and is dropped and supplied from the start end 22a to the coin supply position.

<Other Example 2> FIG. 10 shows an embodiment in which a gutter 23 is used as a coin supply means for the second conveyor 22. The gutter 23 is inclined downward facing the inclined conveyance surface 22b of the second conveyor 22, and the coin C slides or rolls in the gutter 3 and is supplied to the inclined conveyance surface 2b of the second conveyor 22 by dropping. . This mode is particularly suitable when coins are to be supplied next to the lifting device and coins are supplied to the conveyor from a gutter or a discharge chute at a coin outlet of the lifting device.

<Other Example 3> On the other hand, the embodiment shown in FIG. 11 is different from the embodiment shown in FIG.
And a second conveyor 22 ′ having all transport surfaces horizontal.
And a first conveyor 21 ′ for supplying coins on the conveying surface of the second conveyor 22 ′.
This is a method of supplying coins C supplied from the conveyor 21 'onto the transport surface of the second conveyor 22' to a coin supply position. In the illustrated example, the first conveyor also has the entire conveying surface horizontal.

In this embodiment, when no coin is supplied to the coin supply position, as in the other examples described above, FIG.
As shown in (a), the second conveyor 22 'is driven in the direction of the arrow to convey the coin C dropped and supplied from the first conveyor 21' from the start end 22a 'to the end 22c' side. When supplying C, as shown in FIG. 11 (b), the second conveyor 22 'is reversed (not stopped) while the first conveyor 21' is driven, and the coin supplied from the first conveyor 21 ' C is conveyed to the starting end 22a 'along the inclined conveying surface 22b' of the second conveyor 22 'and dropped and supplied from the starting end 22a' to the coin supply position. In this embodiment, a gutter, a chute or the like can be used as a coin supply means for the second conveyor 22 'instead of the first conveyor 21'.

<Other Example 4> In the above examples, the conveying directions of the continuously provided conveyors are the same, but the present invention is not limited to this. For example, as shown in FIG.
Conveyor direction 21 '' and the second conveyor 2
2 '' may be provided so as to face the transport direction. FIG. 12A shows a transport state, and FIG. 12B shows a state in which the second conveyor 22 ″ is reversed to supply coins to the coin supply position.

[0039]

As described above, according to the present invention, since the coin scraping member used conventionally is not used, the coin is caught between the belt surface and the coin scraping member, or the coin is caught in the coin passage. By the accumulation, troubles such as the belt stopping due to friction and the coin scraping member being destroyed do not occur.

Also, by the bridging action between coins,
It is possible to reduce the possibility that the coin supply port is clogged with coins or a large gap is generated in the coin storing portion, and the coin can be smoothly supplied for a long period of time.
