Description

The present invention relates to equipment used in a ball circulation system or the like installed on a game island in which a plurality of pachinko gaming machines and game media rental machines are arranged, and is used to guide a pachinko ball downward. It is related to the ball channel ridge.

A ball circulation system has been introduced and installed between amusement islands in recent amusement stores. For example, the ball circulation system shown in FIG. 4 is a ball storage tank that stores a large amount of pachinko balls in an amusement island, a ball supply device provided at a discharge port of the ball storage tank, and a drain from each pachinko gaming machine. A ball lifting device that lifts the pachinko balls that have been polished upward, an upper tank that temporarily stores the pachinko balls that have been lifted upward, and each pachinko gaming machine and each game media lending machine from the upper tank On the other hand, it is composed of a replenishing bowl for replenishing pachinko balls and an overflow bowl for returning to the ball storage tank. By guiding it into the ball storage tank, the pachinko balls on the island can be circulated. In order to avoid problems such as replenishment problems (shortage of balls).

The upper tank of the ball circulation system described above is provided with a storage unit for temporarily storing pachinko balls. A configuration of this ball circulation system is disclosed in FIG. 7 or FIG.
JP 2006-280539 A

As shown in FIG. 5, the pachinko ball flow passage 25 provided at the lower position in the upper tank 4 is provided with a discharge hole on the bottom surface on the downstream side, and a pipe-shaped discharge for allowing the pachinko ball to flow down into the discharge hole. An outlet 25b is provided continuously. A flow-down hose is press-fitted into the discharge port 25b, and the pachinko balls in the upper tank 4 flow down in the flow-down hose and are collected in the ball storage tank.

However, the operation of press-fitting the flow-down hose into the discharge port 25b connected to the pachinko ball channel rod 25 is such that the outer diameter of the discharge port 25b and the inner diameter of the flow-down hose are substantially the same diameter, and further spiral. Because a downflow hose made of a hard material with an embedded iron core is used, the installation work cannot be easily performed, and time is required.
Further, the discharge port 25b connected to the pachinko ball channel rod 25 is made of sheet metal, and the pachinko balls that have rolled in the pachinko ball channel rod 25 have a momentum at the corner of the sheet metal near the discharge port 25b. Because of frequent collisions, there was a broken hole that spilled pachinko balls during long-term use, and accidents (problems) such as the discharge port 25b itself being broken and falling occurred.
Furthermore, in order to remove static electricity generated in the process of the pachinko ball flowing down the downflow hose, as a countermeasure, for example, a ground wire is separately attached to the mounting bracket at the position where the downflow hose is press-fitted into the discharge port 25b, and the pachinko ball Static electricity was removed by connecting it to the discharge port 25b of the flow path 25, but separately installing and connecting the ground wire was a very dangerous work from work in a high place (about 2 meters). .

In consideration of the above points, work to install a flow-down hose, an accident that occurred in the ball circulation system installed on the amusement island, a fall accident at the discharge port of the pachinko ball flow channel itself, and a flow-down hose Provided is a pachinko ball flow channel for the purpose of solving the problems of static electricity generated in the inside.

In order to solve the above-mentioned problems, claim 1 of the present invention provides a pachinko ball flow channel with a discharge hole formed in the bottom surface on the downstream side and a discharge port having a short cylindrical shape connected to the discharge hole. In this case, the discharge port is formed into the short cylindrical shape by a substantially U-shaped main body portion opened on one side surface and a pressing plate for closing the opened one side surface, and the pachinko ball is formed on the main body portion. This is achieved by inserting the flow down hose to flow down the plate and then sandwiching the flow down hose in the elliptically deformed state on the peripheral wall surface of the discharge port by the pressing plate.

According to a second aspect of the present invention, there is provided the pachinko ball flow channel according to claim 1, wherein the hole diameter of the discharge hole provided in the bottom surface on the downstream side of the pachinko ball flow channel is larger than the inner diameter of the flow hose. This is achieved by adopting a configuration in which the size is smaller than the outer diameter.

According to a third aspect of the present invention, there is provided a pachinko ball passage trough according to claim 1, wherein an iron core is embedded in the flow hose, and the iron core is grounded to the pachinko ball passage trough. Is achieved.

According to the configuration of the first aspect of the present invention, after inserting the flow down hose into the main body of the discharge port, the pressing plate is clamped with a fastener so that the flow down hose is clamped on the peripheral wall surface of the discharge port in an elliptical deformed state. Since it is to be mounted, the mounting work is extremely easy and can be performed in a short time.

According to the configuration of claim 2 of the present invention, the hole diameter of the discharge hole provided in the bottom surface on the downstream side of the pachinko ball flow channel is larger than the inner diameter of the flow hose and smaller than the outer diameter. As a result, the pachinko balls that have been rolling in the pachinko ball channel よ う as before do not collide directly with the corners of the sheet metal near the discharge port, and the flow hose itself (inner diameter part) side Will collide with. As a result, even if it has been used for a long period of time, it is possible to prevent an accident that the discharge port itself falls due to breakage without causing a breakage hole.

According to the configuration of claim 3 of the present invention, an iron core is embedded in the flow down hose, and the inside of the flow down hose is formed by making the iron core in ground contact with the pachinko ball flow channel. Needless to say, the static electricity generated when the pachinko balls flow down is surely removed, and there is no need to separately install and connect a ground wire, which has been performed in a dangerously high place as in the past.

Hereinafter, embodiments will be described in detail with reference to the drawings.

First, the structure of the ball circulation system in which the pachinko ball flow channel of the present invention is used will be described. The ball circulation system here is the same as the configuration described in the background art. The ball circulation system 10 includes a ball storage tank 2 for storing a large amount of pachinko balls in the amusement island 1, a ball supply device 12 provided at an outlet of the ball storage tank 2, and a recovery basket 8 from each pachinko gaming machine. A ball lifting device 3 that lifts the discharged pachinko balls upward while polishing them, an upper tank 4 that temporarily stores the pachinko balls raised upward, and each pachinko machine or game from the upper tank 4 It comprises a replenishment basket 9 for replenishing pachinko balls to the medium lending machine and an overflow basket 11 for returning to the ball storage tank 2. By operating such a ball circulation system 10, pachinko balls are circulated while maintaining the balance of the storage amount in each game island 1. The pachinko balls that have flowed down from the overflow rod 11 are led to the recovery rod 8 via the overflow flow hose 11a at the island end.

Moreover, the storage part 5 for temporarily storing the pachinko balls and the supply / reception part 6 for supplying and receiving pachinko balls with other islands are provided inside the upper tank 4 described above. The pachinko balls stored in the supply / reception unit 6 balance the storage amount of the ball storage tank 2 provided inside the game island with a supply rod and a reception rod (not shown) attached to the outer wall of the upper tank 4. I keep it. The supply / reception unit 6 is partitioned by a partition wall 7 having a plate shape in the vicinity of the center. The partition wall 7 is provided with an overflow window 7a that is opened so as to send surplus pachinko balls to the supply / reception unit 6, and the pachinko balls sent to the supply / reception unit 6 are connected to the pachinko ball flow channel 6a from the overflow channel port 6a. 15 leads to.

Next, the configuration of the pachinko ball channel rod 15 that is the gist of the present invention will be described.
This pachinko ball flow channel 15 will be described in an embodiment in which it is used in the ball circulation system 10 described above.
Pachinko balls that overflow (surplus) in the storage section 5 of the upper tank 4 are sent to the supply / receiving section 6 from an overflow window 7a opened in the partition wall 7, and the pachinko balls sent to the supply / receiving section 6 are overflow channel openings. 6a is collected into the ball storage tank 2 through the pachinko ball flow channel 15.

As shown in FIG. 1, the pachinko ball channel rod 15 is formed in a bowl shape with an open top surface, a discharge hole 15a is provided on the bottom surface on the downstream side, and a discharge port having a short cylindrical shape in the discharge hole 15a. 15b is continuously provided. The discharge port 15b is formed into the short cylindrical shape by a substantially U-shaped main body portion 15c having one side surface opened and a pressing plate 16 for closing the one side surface opened. The discharge hole 15a is formed in a circular shape having a size larger than the inner diameter of the falling hose 17 and smaller than the outer diameter.
The inside (space) of the main body portion 15c is formed with a hose accommodating portion 15d, and after the falling hose 17 is inserted into the hose accommodating portion 15d, the pressing plate 16 is sandwiched in an elliptically deformed state.

The hose accommodating portion 15d inside (space) of the main body portion 15c has a lateral width larger than the diameter of the falling hose 17, and conversely, the depth width is formed smaller. That is, the hose accommodating portion 15d has a size sufficient to cause the falling hose 17 to be deformed (collapsed) from a circular shape to an elliptical state. Further, the main body portion 15c is provided with bent pieces 15e at both ends on the opening side. When the flow down hose 17 is inserted by the bent pieces 15e provided at both ends, it does not fall forward. The bent piece 15e is provided with a mounting hole 15f for mounting the pressing plate 16.

The pressing plate 16 is formed in a shape (for example, a substantially rectangular shape) having a width that closes one side surface opened to the substantially U-shaped main body portion 15c, and is provided with a fastening tool 16a (for example, a screw) at both ends. . Reinforcing pieces 16 b are provided at the upper and lower ends of the pressing plate 16. The reinforcing piece 16b is provided to reinforce the pressing plate 16 so that the pressing plate 16 does not bend even when the fastener 16a of the pressing plate 16 is tightened.

The descending hose 17 is embedded with a spiral iron core 17b over its entire length. Therefore, the embedded iron core 17b can be brought into ground contact with the metal pachinko ball flow channel 15 or the like. Here, the downflow hose 17 is made of a hard hose material made of, for example, vinyl chloride or urethane resin.

The installation work of the flow down hose 17 will be described.
The flow hose 17 is inserted into the discharge port 15b connected to the discharge hole 15a on the downstream side of the pachinko ball channel ridge 15 until the edge of the falling hose 17 contacts the discharge hole 15a. After that, as shown in FIG. 2, the pressing plate 16 is attached to the main body 15c with the fastening tool 16a. At this time, the flow down hose 17 projecting somewhat from between the bent pieces 15e is deformed (collapsed) into an oval shape, and as a result, comes into contact with the four directions (four surfaces) of the peripheral wall surface of the discharge port 15b, and the oval deformation It is pinched in the state (for example, contact / S1 to S4). Therefore, the installation work of the flow down hose 17 becomes easy and can be clamped in a short time.
In the above description, the flow hose 17 is inserted into the discharge port 15b and the end edge is in contact with the discharge hole 15a. However, a slight gap (within the pachinko ball diameter) is opened and held. Also good.

Although the iron core 17b embedded in the downflow hose 17 is grounded to the metal pachinko ball flow passage 15 to remove static electricity, the exhaust made of metal other than the pachinko ball flow passage 15 is used. Static electricity can be transmitted to the outside and removed by making ground contact with any of the outlet 15b, the main body 15c, the pressing plate 16, and the like. Similarly, when the pachinko balls flow down, static electricity generated in the flow down hose 17 is surely removed.

The flow hose 17 is inserted into the main body portion 15c of the discharge port 15b of the pachinko ball flow channel 15 provided in the lower position in the upper tank 4 and is clamped by the pressing plate 16. It may be adopted at the place.
For example, in the main body in the discharge port formed of a short cylindrical shape formed continuously with the overflow bowl 11 formed in a bowl shape in order to return the pachinko balls overflowing from the upper tank 4 of the game island 1 to the ball storage tank 2 The same effect can be obtained by inserting the overflow flow hose 11a and holding it with the pressing plate.

It is the perspective view which inserted the flow down hose in the main-body part of the pachinko ball flow path. It is a top view which shows the elliptical deformation state of the flow-down hose in a discharge port. It is sectional drawing which shows the connection of the discharge port of a pachinko ball flow channel, and a flow-down hose. It is a front view which shows the ball circulation system installed in the amusement island. It is a perspective view which shows the inside of the upper tank of a ball circulation system.
