Description

  The present invention relates to an upper tank for storing pachinko balls circulating in the island in the upper part of the game island in the game island in which a plurality of pachinko gaming machines are arranged.

  In a game island where multiple pachinko machines are arranged in a line on one or both sides, the configuration of a system that circulates pachinko balls stored in the game island is described. For example, a large number of pachinko balls are stored in the game island. A ball storage tank to be moved, a ball supply device provided at a discharge port at an end of the ball storage tank, and a lifting device that lifts the pachinko balls discharged from the ball supply device or each pachinko gaming machine to the recovery basket upward An upper tank for temporarily storing pachinko balls lifted to the upper part of the lifting device, a replenishment bowl for supplying pachinko balls from the upper tank to each pachinko gaming machine and each game medium lending machine, and an upper part It is equipped with an overflow bowl to return the pachinko balls overflowing from the tank to the ball storage tank. By such a circulation mechanism, the pachinko balls on the island circulate and replenish the business. So that there is no hindrance of trouble, and the like.

  By the way, the upper tank installed in the above game island has what is shown in patent document 1, and is comprised as shown in FIG. 7 or FIG. That is, an upper tank 4 that can store pachinko balls lifted from the ball storage tank 2 at the lower part of the game island 1 via the lifting device 3 at the upper part of the game island 1, A partition wall 7 partitions the storage unit 5 for temporarily storing pachinko balls and a supply / reception unit 6 for supplying and receiving pachinko balls and other islands. The partition wall 7 is provided with an overflow port 7a through which the pachinko balls overflowed in the storage unit 5 are sent out to the supply / reception unit 6, and the pachinko balls fed into the supply / reception unit 6 are stored through the overflow channel 6a. Delivery to the tank 2 is possible. The ball storage tank 2 is provided with an upper limit detection switch 14a and a lower limit detection switch 14b on the side wall at a predetermined height. The detection amount of the balls in the ball storage tank 2 is detected by these detection switches. When the supply is reduced, a supply request signal is transmitted to the adjacent island, and when a supply request signal is transmitted from the adjacent island, a shutter (not shown) provided at the supply port 9 is opened, and the supply request signal is transferred as described above. Will be supplied to neighboring islands.

In such a configuration, a guide plate 8 that is inclined downward from the upper part of the storage part 5 toward the upper part of the supply / reception part 6 is usually provided, and the supply port 9 is provided on both the front side and the rear side of the upper tank. Provided (illustrated only on the back side), a supply port 9 on the front side from the center, and a mountain-shaped guide portion 9a inclined downward from the supply port 9 on the back side are provided. Supply is now possible.
Then, the pachinko balls lifted by the lifting device 3 roll from the delivery port 3a onto the guide plate 8 toward the guide portion 9a, and a shutter (not shown) provided at the supply port 9 is opened. When it is sent from the supply port 9 to the adjacent game island through a balance pad, when the shutter is closed, the pachinko balls gradually clog up from the guide portion 9a to the guide plate 8, and then delivered. It is sent to the storage part 5 from the gap 8a of the guide plate 8 provided below the mouth 3a.

However, as described above, when the shutter of the supply port 9 is closed, the pachinko balls stay on the entire guide portion 9a and the vicinity of the gap 8a on the guide plate 8. In this state, for example, when the shutter of the supply port 9 on the back side is opened, the pachinko balls staying on the side inclined to the supply port 9 on the back side on the guide portion 9a are balanced from the supply port 9. Although it is fed to the adjacent island through the eaves, the pachinko balls staying on the inclined side of the supply port 9 on the front side on the guide portion 9a continue to stay as they are, and the upper 8 on the guide plate is approximately half on the front side. This area remains in a state where the pachinko balls are retained.
If it does so, the passage width which the pachinko ball on the guide plate 8 can roll will be about a half of the usual, and the pachinko ball which flows into the storage part 5 from the clearance gap 8a of its own island without flowing to the guide part 9a side will increase. As a result, inconvenience occurred that the rapid supply to the adjacent islands could not be performed.

Yes. Here, one main ball storage tank 2A (a long, substantially rectangular shape and capable of storing about 100,000) and one sub ball storage tank 2B (main ball storage tank) sequentially connected to the main ball storage tank 2A It is a substantially rectangular shape slightly shorter than the tank 2A, and can store about 50,000 pieces).

  Further, a plurality of pachinko gaming machines and gaming medium lending machines are alternately arranged on the gaming island 1 constructed with a frame. Below the pachinko gaming machine, a collection basket 10 for collecting discharged balls (out balls) is provided in an inclined manner toward the lower part of the lifting device 3 (for example, a cloth polishing lifting device).

  Hereinafter, the upper tank 4 of the present embodiment will be described in detail. As shown in FIG. 1 (a), (b) or FIG. 2, the inside of the upper tank 4 has a storage part 5 for storing the balls lifted by the above-described lifting device 3, and the adjacent islands and balls. A supply / reception unit 6 for performing supply / reception is provided. The storage unit 5 and the supply / reception unit 6 are partitioned by a partition wall 7. In addition, a delivery port 17 is provided at the upper part of the storage unit 5 to deliver the balls that have been lifted by the lifting device 3 into the upper tank 4. Further, a discharge port 15 is provided in the lower portion of the side plate 35D of the storage unit 5, and a replenishment basket 11 (see FIG. 7) is attached to the discharge port 15, so that balls are attached to the pachinko gaming machine and each game medium lending machine. Will be supplied.

  Further, the back plate 35B in the upper tank 4 is provided with an upper limit detecting means St and a lower limit detecting means Sd at a predetermined height, so that the amount of balls stored in the storage section 5 is reduced, and the height of the lower limit detecting means Sd. When the decrease is detected, the ball supply device 13 in the game island 1 is driven.

  On the other hand, a first supply port 18a for supplying balls to adjacent islands is provided above the supply / reception unit 6, and a reception port 19a for receiving balls supplied from the adjacent islands is provided below the first supply ports 18a. The supply and reception of the adjacent islands and balls are performed via the balance passages 20A and 20B (see FIG. 4 or 5) connected to the one supply port 18a and the reception port 19a. In addition, an overflow opening 22 (see FIG. 2) is provided at the bottom of the hollow bottom plate 21 formed in the lower part of the supply / reception unit 6, and the overflow channel 16 has a downward slope below the overflow opening 22. The overflow rod 12 (see FIG. 7) is attached to the flow-down port 24 formed in the lower part of the overflow channel 16.

In addition, the upper tank 4 is provided at a top portion of the partition wall 7 separating the storage portion 5 and the supply / reception portion 6 from the supply / reception portion 6 so as to be gently inclined downward, and is transported by the lifting device 3 to be a delivery port. A guide plate 23 for guiding from 17 to the supply / reception unit 6 side is provided. In addition, a guide unit 25 is provided above the supply / reception unit 6. The guide portion 25 includes a first guide portion 25a inclined downward from the inclined top portion 25c to the first supply port 18a, and a second guide portion 25b inclined downward from the inclined top portion 25c toward the second supply port. The balls formed in the mountain shape and guided by the guide plate 23 are guided to the first supply port 18a and the second supply port. That is, the first guide portion 25a and the second guide portion 25b are inclined in opposite directions with respect to the inclined top portion 25c, and the inclination of the guide plate 23 is substantially the same as the inclination of the first guide portion 25a and the second guide portion 25b. The vertical direction.
Further, as shown in FIG. 1, the inclined top portion 25 c is provided on the front side from the center in the front-rear direction above the supply and reception unit 6, but balls entering the upper tank from the lifting device 3 through the delivery port 17 are lifted. Since the feeding device 3 vigorously enters, most of the balls guided from the guide plate 23 to the guide portion 25 roll near the rising piece 29 from the front plate 35A, which will be described later, and are substantially guided onto the inclined top portion 25c. The

  Further, as shown in FIG. 1A, a gap 36 is provided between the back plate 35 </ b> B in which the delivery port 17 is formed and the guide plate 23. Also, on the opposite side of the back plate 35B, although not shown in FIGS. 1B, 2 and 3, the front plate 35A of the upper tank 4 is provided as shown in FIGS. The storage part 5 and the supply / reception part 6 have an internal space with the partition wall 7 as a boundary by the front plate 35A, the back plate 35B, and the side plates 35C and 35D.

  Further, as shown in FIGS. 1 (a) and 1 (b), the guide plate 23 has a guide plate 23 standing upright along the opposite edge of the back plate 35B from the middle of the storage portion 5 to the wall surface side. A piece 29 is formed, and an opening 30 through which the balls can be circulated is formed in the rising piece 29, and a reservoir passage 31 is provided below the opening 30.

  The storage portion passage 31 is a passage through which a part of the ball mounted on the guide plate 23 flows to the storage portion 5, and the inside is cylindrical by being closed by the front plate 35 </ b> A of the storage portion 5. And an upper opening 31a that opens toward the opening 30 of the rising piece 29 and a lower opening 31b that opens downward in the reservoir 5, and the lower opening 31b is located from the position of the lower limit detection means Sd. Is also formed to be higher by a predetermined amount. In such a reservoir 31, when the balls in the reservoir 5 exceed the lower limit detection means Sd and become a predetermined amount (the upper opening 31 a that is the upper limit of the reservoir 31) or more, the reservoir 31 is blocked. When all the balls are transferred to the guide unit 25 and the balls in the storage unit 5 have passed the lower limit detection means Sd and become less than a predetermined amount (the upper opening 31a which is the upper limit of the storage unit passage 31), the storage is performed. Part of the balls placed on the guide plate 23 with the part passage 31 opened are transferred to the storage part 5 through the storage part passage 31 and the remaining balls are transferred to the guide part 25.

  Furthermore, as shown in FIG. 1B or FIG. 2, an overflow passage 32 is formed in the storage portion 5 along the partition wall 7. The overflow passage 32 is formed in a cylindrical shape, and has an inlet 32a at an upper position in the storage portion 5 and an outlet 32b at a lower position of the partition wall 7, so that the balls stored in the storage portion 5 are overflowed. The cylindrical lower opening of the passage 32 is closed. Further, when balls are accumulated in the storage portion 5 and enter the overflow passage 32 from the inlet 32a of the overflow passage 32, the balls fall on the balls that have closed the lower opening of the overflow passage 32 and are further accumulated. At the point of time when the outlet 32b is reached, it is transferred from the outlet 32b to the supply / receiving unit 6.

  In addition, as shown in FIG. 2, a buffer plate 33 made of urethane material is fixed in a hanging manner from a fitting 33a fixed to the upper portion of the outlet 32b of the overflow passage 32 in a state slightly spaced from the wall surface of the partition wall 7. Since the ball that has passed through the overflow passage 32 hits the cushioning material 33 and falls to the bottom plate 21 of the supply / reception unit 6 from a low position, there is little impact on the bottom plate 21 of the supply / reception unit 6 and the effect of noise reduction is achieved. In addition, after the balls have fallen onto the bottom plate 21 without being scattered, the balls pass through the overflow opening 22 of the supply / receiving unit 6 and are transferred to the overflow channel 16. With such a configuration, as described later, a simple configuration in which a ball passage entering from another island through the receiving port 19a of the upper tank 4 and a ball passage entering through the overflow passage 32 are made common. It becomes possible to do. Further, by providing the buffer material 33 in this way, it is possible to have a configuration that does not get in the way even if the internal connection passage 20C (see FIG. 5) is provided in the supply / reception unit 6 as described later.

  On the other hand, as shown in FIG. 1B or FIG. 4, the guide portion 25 having a step at the lower portion of the downstream end portion of the guide plate 23 is provided above the supply / reception portion 6 as described above. At one end of the guide portion 25, a first supply port 18a for moving the ball guided by the guide plate 23 to another island is formed. The supply port 18a is provided with an open / close shutter 34a driven by a motor M, and the open / close shutter 34a switches between a state where balls can be circulated and a state where the balls cannot be circulated through the guide portion 25. Further, as shown in FIG. 1A, a second supply port 18b is formed on the opposite side (front plate 35A side) of the first supply port 18a, and a motor is also provided in the second supply port 18b. An open / close shutter 34b by driving is provided. In such a configuration, as shown in FIG. 4, the first supply port 18a is connected to the balance passage 20A connected to the receiving port of the adjacent island, and the second supply port 18b is connected to the first supply port 18a. A balance passage 20D connected to the receiving port of the adjacent island on the opposite side to the supply port 18a is connected. Further, a receiving port 19a is provided below the first supply port 18a, and a balance passage 20B connected to the supply port of the adjacent island is connected to the receiving port 19a.

  In the above configuration, when the lower limit detection means Sd of the storage unit 5 does not detect a ball, the amount of replenishment to the game machine on the own island is reduced, so that the OFF signal of the lower limit detection means Sd By closing the first and second supply ports 18a, 18b, substantially all of the balls placed on the guide plate 23 are moved to the storage unit 5 via the storage unit passage 31, and the balls in the storage unit 5 are detected at the lower limit. The lower opening 31b of the reservoir passage 31 is closed over the means Sd. Further, by accumulating balls up to the upper opening 31 a of the storage portion passage 31, substantially all of the balls are guided to the guide portion 25, and further, the balls in the storage portion 5 are reduced to lower the lower opening 31 b of the storage portion passage 31. As a result of the opening, a part of the balls placed on the guide plate 23 is transferred to the storage unit 5 through the storage unit passage 31 and the remaining balls are guided to the guide unit 25.

  In addition, when there is no ball supply request signal from the adjacent island, the balls guided to the guide unit 25 are directed to the guide plate 23 in order to maintain the first and second supply ports 18a, 18b closed. In the case where it overflows from the mounted state and falls into the storage part 5 from the gap 36 (see FIG. 1A) and the storage part passage 31 is vacant, the storage part passage passes through the opening 30 of the guide plate 23. Fall to 31.

Further, when the first and second supply ports 18a and 18b are closed as described above, the ball stays in the entire area on the guide portion 25 and in the vicinity of the gap 36 on the guide plate 23. .
From this state, for example, when the opening / closing shutter 34a of the first supply port 18a is opened, the balls staying on the first guide portion 25a flow from the first supply port 18a to the balance passage, and accordingly, on the guide plate 23. The staying ball also flows to the guide portion 25 and flows from the first guide portion 25a to the balance passage through the first supply port 18a. The ball staying on the second guide portion 25b remains in a staying state.
At this time, when the guide plate 23 has only a length up to the partition wall 7 and does not extend to the upper side of the guide portion 25 as in the prior art, the entire second guide portion 25b and the guide plate 23 are The ball remains in about half of the area on the front plate 35A side, and the width of the passage through which the ball can flow on the guide plate 23 is about half of the normal width, which hinders quick supply to the adjacent island. I was coming.
However, in the present embodiment, since the guide plate 23 that is inclined downward toward the guide portion 25 with a smooth bottom surface extends to above the guide portion 25, the balls on the guide plate 23 are smoothly directed toward the guide portion 25. The ball that flows and stays on the guide plate 23 is almost eliminated, and can be quickly supplied to the adjacent island.

  Similarly, even when the opening / closing shutter 34b of the second supply port 18b is opened from the state where the ball stays in the vicinity of the entire gap on the guide portion 25 and the gap 36 on the guide plate 23, the back side With only a portion of the balls remaining at the tip of the (first guide portion 25a side), most balls flow smoothly toward the guide portion 25 without stagnating and can be quickly supplied to the adjacent island. .

Moreover, as for the height of the step between the guide plate 23 and the guide portion 25, it is desirable that the higher one is easier to flow without staying on the guide plate 23, and there is a step of one ball or more. The bottom surface of the guide plate 23 may be in contact with the upper surface of the guide portion 25.
As for the length of the guide plate 23 that faces the guide portion 25, the longer it extends, the easier the balls do not stay on the guide plate 23 and the second supply port 18a and the second supply port 18a as in the embodiment. When the supply port 18b is provided at a position shifted in the left-right direction (inclination direction of the guide plate 23) above the supply receiving unit 6, the second supply port 18b provided at least on the front side when viewed from the guide plate 23 is provided. It is desirable to face the substantially central position of the supply port 18b. In the present embodiment, it faces the central position between the first supply port 18a and the second supply port 18b (see FIG. 1).
Further, the guide plate 23 provided with the tip facing above the guide portion 25 of the present embodiment has the first supply port 18a and the second supply port 18b provided in a straight line in the front-rear direction above the supply receiving unit 6. Even the upper tank provided can be used.

  When the storage part 5 of the upper tank 4 is filled with balls, it flows from the inlet 32a of the overflow passage 32 through the outlet 32b to the supply / reception part 6 and hits the buffer plate 33 as described above. It falls on the bottom plate 21, passes through the overflow opening 22 of the supply / receiving unit 6, and is transferred to the overflow channel 16.

  In the present embodiment, as shown in FIG. 4, the supply port 18 provided in the upper tank 4 on the own island is connected to the inner side of the supply / receiver 6 from the supply port 18 provided in the upper tank 4 on the adjacent island. A receiving port buffer member 26 is provided. As shown in FIG. 6, the receiving port buffer member 26 includes a drooping elastic member 27 made of urethane or the like that causes a ball entering the supply receiving unit 6 from the receiving port 19 a to collide in a buffered state, and a lower portion of the drooping elastic member 27. And a curved elastic member 28 made of urethane or the like that is curved downward and convex, and when the ball is transferred from the adjacent island to the supply and receiving part 6 of the own island, the transferred ball is supplied to the receiving port 19a of the own island. It is made to receive with the receiving port buffer member 26 provided.

  With such a configuration, when a ball supplied from an adjacent island enters the receiving port 19a through the balance passage 20B (see FIG. 4), the ball is first received by the drooping elastic member 27, thereby reducing the collision sound. The speed can be reduced without bouncing the ball, and after that, by falling on the curved elastic member 28, the ball falls from the low position to the bottom surface of the supply / receiving unit 6 while being collected in a narrow area below the curved elastic member 28. Therefore, there is little impact on the bottom, no high noise is generated, and balls are not scattered, and are transferred to the overflow channel 16 through the overflow opening 22 of the supply / reception unit 6, and the overflow rod 12 To the ball storage tank 2.

  Furthermore, as another embodiment, as shown in FIG. 5, a balance passage 20B is connected from the supply port of the adjacent island to the supply port 19a of the upper tank 4 of the own island, and the supply port of the own island is connected from the supply port of the adjacent island. It is possible to transfer balls to 19a. In addition, the internal connection passage 20C is connected to the receiving port 19a and the communication port 19b provided on the opposite side of the receiving port 19a inside the upper tank 4 of the own island, and the ball from the balance passage 20B is received by the receiving port 19a. It is possible to transfer to the opposite communication port 19b and to feed to the adjacent island on the opposite side via the balance passage 20E connected to the communication port 19b.

  Further, the internal connection passage 20C can be removed. By removing the internal connection passage 20C, as shown in FIG. 4, the balls from the balance passage 20B are passed from the receiving port 19a through the receiving port buffer member 26. It can be transferred to the inside of the supply / reception unit 6. With such a configuration, the ball can be transferred directly from the adjacent island to the opposite adjacent island through the own island. If the above-described internal connection passage 20C is not provided, the balance passage (saddle member) passes over the own island from the adjacent island to the adjacent island on the opposite side, and a very long saddle member. However, the eaves member connecting the islands has a complicated and complicated configuration, but the configuration of the above-described embodiment makes such a long eaves member unnecessary.
