Field of the Invention The present invention relates to a game medium polishing apparatus which is installed in a lower stage of a game machine island in which a plurality of game machines are arranged in parallel and which conveys a game medium used in the game machine while polishing the same. Here, the game machine mainly refers to a pachinko machine, and the game medium is a pachinko ball.

[0002]

2. Description of the Related Art Conventionally, as this type of apparatus, for example, there is a game medium polishing apparatus 1 as shown in FIG.

That is, the stirring han cylinder 4 in which the coil body 3 which is driven to rotate by the motor 2 is installed, the separating portion 5 of the abrasive material C following the discharge port 4a of the stirring han cylinder 4, and the separating portion 5. It has a return tube 6 that connects the receiving port 4b of the stirring fan tube 4.

The pachinko ball P enters the receiving port 4b from the carry-in path 7 and the discharging port 6a of the return cylinder 6 to the receiving port 4 of the stirring han cylinder 4.
The abrasive material C entered in b is mixed and agitated by the coil body 3 in the agitating cylinder 4 and discharged from the discharge port 4a, and the abrasive material C is separated by the separating portion 5 so that only the pachinko ball P comes from the gutter 8. Sent out. The abrasive material C separated by the separating portion 5 falls on the hopper 6b, passes through the inside of the return cylinder 6 and returns to the discharge port 6a for circulation. The decrease amount of the abrasive C and the like are replenished from the replenishment tank 9.

Such a polishing apparatus 1 is shown, for example, in FIG.
It is installed integrally with the gaming machine island 10 as shown in FIG. Above the gaming machine island 10, a storage tank 11 for pachinko balls polished by the gaming medium polishing apparatus 1 is arranged. Further, a lower tank 13 that stores a spare pachinko ball is connected to the storage tank 11 via a bypass 12. When the amount of pachinko balls in the storage tank 11 is reduced, the lower tank 13 is used by the game media polishing device 1.
The pachinko balls stored in the storage tank 11 are supplied to the storage tank 11.

As shown in FIG. 13 and FIG. 14, the gaming machine island 10 is constructed by arranging a plurality of pachinko machines 14 side by side in a lateral direction side by side. The back faces of the pachinko machine rows arranged in a line are arranged so as to be separated from each other. In the space between the backs of the pachinko machine rows forming the middle stage of the island, a paper piece conveying device 16 is arranged to convey the banknotes sent out from the ball lending machine 15 in the island lateral direction.

As described above, since it is necessary to secure a space for arranging the paper piece transporting device 16 between the respective pachinko machine rows, the depth of the entire island is at least two pachinko machines 14. Paper piece transport device 1 with a corresponding depth width
It was necessary to set the size in consideration of 6.

[0008]

Therefore, there are problems that the number of parts is increased and the overall configuration tends to be complicated, which is a great obstacle in reducing the cost and requires a very large installation space. Moreover, a separate structure for separating the pachinko ball and the abrasive material C is required, and a part of the abrasive material C is not separated but is carried together with the pachinko ball.
There is also a risk that the pachinko machine 14 may enter the board surface and cause a failure. Further, since there is unevenness in the quantitative ratio of the abrasive C to each pachinko ball during polishing, it is unavoidable that unevenness occurs in the polished state of the polished pachinko ball.

Further, in the conventional gaming machine island 10 equipped with the gaming medium polishing device 1, the depth width thereof is a pachinko machine 14
The size is almost standardized by adding the paper piece conveying device 16 to the two units. Therefore, even if you want to increase the number of pachinko machines without expanding the floor area of the game store, in relation to the island width,
The problem was that the number of islands that could be installed on the floor was limited. In view of such circumstances, there has been a strong demand for the development of a space-saving gaming machine island that can reduce the occupied space in the depth direction of the island and increase the number of islands that can be installed on the floor.

Here, the polishing material is composed mainly of, for example, 6 nylon or 66 nylon, and is also mixed with a static electricity removing material, a polishing enhancing material, or is synthesized with other synthetic resin, fiber material or the like.
Only one of the conveyor belts 32 of the pair of conveyors 31a and 31b may be made of an abrasive material, but by making both conveyor belts 32 of an abrasive material, more effective polishing can be performed.

As shown in FIG. 1, the pachinko balls discharged from the respective pachinko balls 21 are introduced from the ball receiving gutter 43 to the starting end side between the pair of conveyors 31a and 31b, and the upper and lower parts are maintained at the optimum intervals. While being sandwiched by the conveyor belt 32, it is polished by the conveyor belt 32 while moving toward the terminal end side.

Since the upper and lower conveyor belts 32 have different rotational speeds and different rotational directions, the pachinko balls are evenly sandwiched between the conveyor belts 32 while being rotated, so that the pachinko balls are evenly polished.

The pachinko balls polished by the game medium polishing device 30 are discharged and then stored in the game medium polishing storage portion 20A which is the lower stage 20A of the island. The game media polishing storage unit 20A directly functions as a storage tank for pachinko balls. As described above, the game medium polishing apparatus 30 of the present invention is capable of polishing the pachinko ball by effectively utilizing the space of the island lower tier 20A.

The pachinko balls in the game media polishing storage section 20A are transferred to the lower end of the lifting mechanism 60 by the rotation of the spiral body 50. Subsequently, the pachinko balls are scooped up by the lifting mechanism 60 and lifted to the island upper stage 20C, and the supply gutter 71
While pausing, each pachinko machine 21 and ball rental machine 2 in the middle 20B of the island
Reduced to 7.

With a long-term use, the diameter of the pachinko balls becomes slightly smaller, and the distance between the pachinko balls and the conveying belt 32 becomes relatively large. The polishing power and the holding power can be restored by adjusting to. It can also be automatically adjusted.

Next, the second embodiment will be described.

6 to 8 show a second embodiment of the game medium polishing apparatus 30.

The same parts as those in the first embodiment are designated by the same reference numerals, and the duplicated description will be omitted.

As shown in FIG. 6, also in the game medium polishing apparatus 30 of the present embodiment, a pair of conveyors 31a and 31b each having a conveyor belt 32 are vertically arranged so that the conveyor belts 32 face each other and the island lower stage. The basic arrangement in which they are installed side by side along the longitudinal direction and the conveyor belt 32
It is the same as in the first embodiment that at least one of them is formed of an abrasive.

The feature of this embodiment is that it is provided with a tension adjusting pulley 39 for adjusting the tension of the conveyor belt 32 by pushing the conveyor belt 32 outward on the side opposite to the side where they face each other. It is that you are. The tension adjusting pulley 39 is arranged near the drive pulleys 33 of the pair of conveyors 31a and 31b and between the vertically extending conveyor belts 32. As shown in FIG. 8, the tension adjusting pulley 39 is attached to the same shaft body A in two parts.

As shown in FIGS. 7 and 8, in the present embodiment, the support 35 extends along the side surfaces of the conveyors 31a and 31b. A long hole S for receiving the shaft body A of the tension adjusting pulley 39 is formed in the support body 35. The shaft A is slidably inserted vertically along the long hole S. Above the long hole S, the connection body C is provided so as to connect the support bodies 35 arranged on both sides of the conveyors 31a and 31b. The connecting body C is provided with a through hole, and the rod R penetrates therethrough. The diameter of the rod R is slightly smaller than the diameter of the through hole, and the rod R can smoothly move up and down in the through hole. In order to prevent the rod R from coming off the through hole, a removable stopper having a diameter larger than that of the through hole is attached to the end of the rod R protruding upward from the connecting body C.

The other end of the rod R is formed in a ring shape, and the shaft A of the tension adjusting pulley 39 is attached so as to penetrate through the ring. A coil spring CS is mounted between the ring-shaped end of the rod R and the connecting body C so as to surround the rod R.

Next, the operation will be described.

When the game medium polishing device 30 is used for a long period of time, the conveyor belt 32 stretches and loosens, which reduces the ability to polish the pachinko balls and also causes the pachinko balls to move between the conveyor belts 32. The holding power to hold is also reduced. However, in this embodiment, when the conveyors 31a and 31b are assembled, the coil spring CS is inserted into the rod R in a contracted state, so that the conveyor belt 32 is always attached to the shaft A of the tension adjusting pulley 39. Force is applied in the direction to push it outward. On the other hand, since the conveyor belt 32 exerts a reaction force on the tension adjusting pulley 39, the conveyor belt 32 maintains a constant tension. Therefore, when the conveyor belt 32 stretches due to a change with time and the force for the conveyor belt 32 to push back the tension adjusting pulley 39 is weakened, the tension adjusting pulley 39 is caused by the elastic force of the coil spring CS.
Pushes the conveyor belt 32 further outward. As a result, the tension of the conveyor belt 32 is restored, and the force of the tension adjusting pulley 39 pushing out the conveyor belt 32 and the force of the conveyor belt 32 pushing back the tension adjusting pulley 39 are balanced, that is, the most appropriate tension of the conveyor belt 32. The state is maintained, and a good polishing state can be maintained.

Although the two embodiments have been described above, the game medium polishing apparatus further includes the interval setting mechanism 37 or the interval adjusting mechanism 38 of the first embodiment and the tension adjusting pulley 39 of the second embodiment. The polishing ability and holding power of the pachinko ball can be maintained well.

The game medium polishing apparatus 3 according to the present invention
0 and the gaming machine island 20 are not limited to the above embodiment. For example, the game machine 21 is not limited to a pachinko machine, and may be a slot machine or the like that uses medals as a game medium.
