JP 2003-154148 A (paragraphs [0044] to [0087], FIG. 1)

  By the way, in this lifting device, since a large frictional force acts on almost all the game balls on the guide rail, a large driving force is required to move the lifting belt. That is, there is a problem that a lot of energy (electric power) is required for lifting the game ball.

  In order to solve this problem, the section over which the polishing belt is passed (the polishing section) is shortened so that a large frictional force acts only on a part of the game balls on the guide rail (that is, the game balls in the polishing section). It is conceivable to construct a lifting device. However, in this case, the driving force required for moving the lifting belt can be reduced, and the energy required for lifting the game ball can be reduced, but the polishing of the game ball is caused by the shortened polishing section. Sometimes it was insufficient.

  Therefore, an object of the present invention is to provide a lifting device that can sufficiently polish a game medium while reducing energy required for lifting the game medium.

In order to achieve the above object, the invention according to claim 1 is provided with a take-in port for taking in game media used in a game, and provided above the take-in port, and processes gaming machines and game media. A discharge port for discharging the game medium to a supply path provided on the gaming machine island to supply the game medium to the processing device, and an upper roller and a lower pulley along the transport path from the intake port to the discharge port . By circulating the endless belt that is passed between them, the game medium taken in from the take-in port is lifted to the discharge port, and is provided on the feed path, and is transported by the lift means In a lifting device including a polishing member that polishes a game medium, the game medium is provided in a position before the game medium reaches the discharge port on the transfer path, and the game medium is discharged to a path that leads the game medium to the intake port. Secondary outlets and games in the supply route A discharge means for discharging the game medium on the transport path from the secondary discharge port when the body storage amount reaches a first predetermined amount set in advance, and between the intake port and the secondary discharge port A polishing member is provided on the surface.

In this transporting device, when the transporting means transports the game medium from the intake port to the discharge port of the transporting device, the game medium is polished between the intake port and the sub-discharge port. When the storage amount of the game media in the supply route of the gaming machine island reaches the first specified amount, the discharge means discharges the game media on the transport route from the sub-discharge port on the transport route and is discharged The game medium is circulated to the intake port of the transporting device through a path that leads the game medium to the intake port .

  That is, in this lifting device, a large frictional force acts only on the gaming medium on the polishing member provided between the intake port and the sub-discharge port among the gaming media being transported on the lifting path. Therefore, the game medium can be transported with less energy than when the polishing member is provided in the entire transport path.

  Then, if the storage amount that can be reached when the game medium is not smoothly supplied from the supply path to the gaming machine or the processing device is set to the first prescribed amount, the game medium is stopped in the gaming machine island, When moisture in the air adheres to the surface and rust is likely to occur, the game medium is circulated between the auxiliary discharge port and the intake port of the lifting device without being lifted to the supply path, and the polishing member Polish repeatedly. Thereby, even with the polishing member provided only between the intake port and the sub discharge port, the game medium can be sufficiently polished.

As described above, according to the present invention, it is possible to provide a transporting apparatus that can sufficiently polish a game medium while reducing energy required for transporting the game medium.
The supply path may be provided with a storage mechanism for temporarily storing game media.

Examples of the processing device include a counter that counts the number of game media, and a lending machine that rents game media to a player (the same applies hereinafter).
By the way, when the operating rate of gaming machines and processing devices installed on the gaming machine island is high (that is, when many gaming machines and processing devices are operating), many games at once from the supply route of the gaming machine island A medium may be supplied to each gaming machine or each processing device. Here, in such a case, in order to prevent the supply path from becoming empty, even if the storage amount of game balls in the supply path reaches the first specified amount, the lifting device supplies the game medium to the supply path. It is necessary to continue to lift. Therefore, it is preferable that the lifting device discharges only a part of the game media from the sub discharge port and transports the remaining game media to the supply path.
Therefore, as described in claim 2, in the lifting device according to claim 1, the lifting means is configured to play the game while the endless belt presses the game medium against the guide rail erected along the lifting path. It is configured to lift the medium to the discharge port, the sub discharge port is formed in the guide rail so that the opening width is smaller than the width of the guide rail, and the intake port is used to connect the game medium to the guide rail. It is good to provide the guide means for aligning in the width direction and guiding to the lifting means.
Thereby, even if the storage amount of the game medium in the supply path of the gaming machine island reaches the first specified amount, it is possible to continue to lift some of the game balls. That is, even if the operating rate of pachinko gaming machines on the gaming machine island suddenly increases, the gaming media in the supply path of the gaming machine island will not be emptied.

  However, in this case, if the operation rate of the gaming machine or the processing device is low or the supply path is clogged, the storage amount of the game medium in the supply path continues to increase after reaching the first specified amount, and the game medium is supplied. It is thought that it overflows from the route.

Therefore, as described in claim 3 , the lifting device stops the lifting means when the storage amount of the game medium in the supply path reaches a second specified amount that is larger than the first specified amount. It is desirable to provide a sending stop means.

  That is, if the storage amount of the game medium that can be reached when the supply path becomes full is set to the second specified amount, the supply path for the game medium is supplied even though the supply path is full of game media. Can be prevented from being lifted.

According to the fourth aspect of the present invention, if the auxiliary discharge port is provided on the guide rail so as to be openable and closable, and the discharge means is provided with an opening means for opening the auxiliary discharge port, the game medium is discharged with a simple configuration. be able to.

Further, in this case, as in claim 5, wherein the discharge means, if Sonaere a pressing means for pressing the game medium toward the secondary outlet, reliably game media can be discharged from the sub-discharge port.
Further, in this case, as described in claim 6 , when the storage amount of the game medium in the supply path reaches the first specified amount and then becomes less than the first specified amount, It is desirable to provide a shielding means for shielding the intake port for a predetermined time set in advance.

That is, since the game medium is not transported to the sub discharge port for a specified time, the on-off valve can be easily closed during this time.
By the way, the invention described in claim 7 is a lifting device according to any one of claims 1 to 6 , a supply path for supplying game media to a processing device for processing gaming machines and game media, and a lifting device. It is a gaming machine island characterized by having a circulation path to the intake of the.

That is, this gaming machine island is a gaming machine island provided with the lifting device according to any one of claims 1 to 6 and components necessary for this, and according to any one of claims 1 to 6 . The same effect as the lifting device can be obtained.

Here, as described in claim 7 , if the circulation path includes a collection path for collecting the game media discharged from the gaming machine or the processing device, a new circulation path is provided in that amount on the gaming machine island. There is no need.

  In addition, the collection | recovery path | route may be provided with the storage mechanism for temporarily storing a game medium similarly to the supply path | route.

When the amount of game balls stored in the upper tank 7 reaches the upper part of the upper tank 7, the game balls being transported are discharged from the sub discharge port 67 to the discharge rod 35, and the sub storage tank 25 and the main storage tank 23 are connected. Then, it is circulated to the lifting device 27. When the supply balls 9 and 11 and the overflow bags 31 and 33 are clogged and the amount of game balls stored in the upper tank 7 reaches the upper end of the upper tank 7 (that is, the upper tank 7 is filled with game balls). Then, the lifting of the game ball is stopped.

  That is, according to this gaming machine island 1, only a large frictional force acts only on the game ball on the guide rail 61b among the game balls lifted on the guide rail 61. A game ball can be lifted with less energy than a gaming machine island equipped with a lifting device with a cloth belt.

  Then, when the game ball stops in the upper tank 7 and moisture in the air adheres to the surface of the game ball and rust is likely to occur, the game ball is not lifted up to the upper tank 7 and the lifting device 27 Since it is circulated between the auxiliary discharge port 67 and the take-in portion 39 and repeatedly ground by the cloth belt 63, the game ball is sufficiently ground even if the cloth belt 63 is not hooked on the entire guide rail 61. be able to. Further, since it is not necessary to hang the cloth belt 63 on the entire guide rail 61, the cloth belt 63 can be replaced easily.

  Further, since the opening width of the sub discharge port 67 of the lifting device 27 is set to be smaller than the width of the guide rail 61a, even if the amount of game balls stored in the upper tank 7 reaches the upper part of the upper tank 7, it is Part of the game balls can continue to be transported to the upper tank 7. That is, even if the operating rate of the pachinko gaming machine on the gaming machine island 1 suddenly increases, the gaming ball inside the upper tank 7 will not be emptied.

  On the other hand, when the upper tank 7 is filled with game balls due to clogging of the replenishment baskets 9 and 11 and overflow baskets 31 and 33, the upper tank is stopped to stop the lifting of the game balls. Even though 7 is full of game balls, the game balls will not be lifted.

In the present embodiment, the lifting unit 37 corresponds to the lifting means of the present invention, and the second proximity switch 103 and the motor 47 correspond to the lifting stop means of the present invention.
In the present embodiment, the first proximity switch 101, the actuators 55 and 65, the small roller 51a, the rod 75, and the link 71 correspond to the discharge means of the present invention.

In the present embodiment, the gate 83 and the motor 85 of the take-in portion 39, the screws 87 and 91, the cocked belt 89, and the guide rail 93 correspond to the shielding means of the present invention.
Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and it goes without saying that various forms can be taken as long as they belong to the technical scope of the present invention. .

  For example, in the embodiment described above, when the second proximity switch 103 is turned on to prevent the game ball from being lifted even though the upper tank 7 is full of game balls, the motor 47 is turned on. Although stopped, the gate 83 of the take-in portion 39 may be lowered to prevent the game ball from being lifted.

  Moreover, in the said embodiment, although the width | variety of the sub discharge port 67 was set smaller than the width | variety of the guide rail 61a, you may set the width | variety of the sub discharge port 67 similarly to the width | variety of the guide rail 61a. In this case, when the auxiliary discharge port 67 is opened, all the game balls that have reached the guide rail 61a from the guide rail 61b are discharged to the discharge rod 35, so that the storage amount of the game balls reaches the upper end of the upper tank 7. This prevents the upper tank 7 from being filled with game balls.

  In addition, while the opening width of the sub discharge port 67 is set in this way, the open / close valve 69 may be configured so that the sub discharge port 67 is partially opened or fully opened depending on the situation. In this case, when the storage amount of the game ball in the upper tank 7 reaches the upper part of the upper tank 7, by opening a part of the sub discharge port 67, a part of the upper ball is discharged while the game ball is discharged. 7 can be lifted. When the upper tank 7 is filled with game balls, all of the game balls being lifted can be discharged by opening all of the auxiliary discharge ports 67 to prevent the transfer to the upper tank 7. .

Moreover, in the said embodiment, although the discharge tank 35 was connected to the sub storage tank 25, you may connect to either the main storage tank 23 or the collection tanks 19 and 21.
