Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball receiving gutter in a discharging portion after a pachinko ball is lifted up in a pachinko ball lifting device or a lifting polishing device.

[0002]

2. Description of the Related Art Conventionally, at a pachinko game hall,
For each pachinko island, a collection gutter for collecting and delivering out balls from each pachinko machine is arranged in the direction in which the pachinko machines are lined up. It is pumped to the upper part and supplied again as a game ball or a prize ball to the distribution gutter arranged at the upper part of the island.

As such a pachinko ball hoisting device, for example, one having a guide member having a gutter groove through which the pachinko ball passes and a conveyor belt for conveying the pachinko ball while crimping the pachinko ball to the gutter groove side are known. . Specifically, the pachinko balls are introduced into the lower end entrance portion, guided between the guide member and the conveyor belt, and are pressed upward by the relative pressure of the pachinko balls and the conveying force of the conveyor belt. Then, it is discharged from the discharge part ball receiving gutter at the upper end and flows into the distribution gutter. Further, in recent years, in this pachinko ball lifting device, a pachinko ball lifting and polishing device has been developed, which polishes the pachinko balls by friction with a guide member or a conveyor belt in the lifting process.

[0004]

However, the discharging part ball receiving gutter in the conventional pachinko ball hoisting devices has a box-shaped cross section arranged in the vicinity of the upper drum 50 as shown in FIG. Alternatively, the U-shaped ball receiving gutter 51 is provided as close to the upper end drum as possible so as not to be clogged.
When the pachinko balls are non-uniformly conveyed in the width direction by the lifting device and a large number of pachinko balls are partially discharged to one place, or as shown in FIG. If there is dust, dirt, or foreign matter 20 accumulated on the road surface, and this is the first obstacle, and the flow of the balls is stopped in a fan shape, etc., in the gap between the upper end drum 50 and the discharge part ball receiving gutter 51. In some cases, the pachinko balls were clogged and this acted as a brake to forcibly stop the rotation of the upper end drum 50. Due to such a situation, there have been problems such that pachinko balls are not supplied to each pachinko machine, or the device is broken, and in the worst case, the game of the entire island must be stopped.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to propose a ball receiving gutter which eliminates the ball clogging at the discharging portion in a pachinko ball lifting device or a lifting polishing device.

[0006]

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention is directed to a moving surface of a gutter through which a pachinko ball flows, along a longitudinal direction of the gutter, in which a width of a flow path in which the pachinko ball flows in series. A plurality of pachinko ball flow passage grooves are formed in the gutter width direction, and the entire moving surface of the gutter is a through hole surface. In this case, it is preferable that the lattice through-hole surface forming member is a metal plate and / or a step portion is provided in the middle of the gutter.

[0007]

In the discharge part ball receiving gutter of the present invention, a pachinko ball flow channel having a width in which the pachinko balls flow in a serial state is formed on the pachinko ball flow channel surface along the longitudinal direction of the gutter, and the moving surface thereof. As the through-hole surface. Therefore, when the pachinko ball rolls and flows, the edge of the through hole and the pachinko ball come into contact with each other, so that the dirt and dust adhering to the pachinko ball are peeled off, and the ball passes through the through hole and moves downward. Since it falls into the flow path, hand dust and dust are not accumulated on the flow path surface, and the clogging phenomenon of pachinko balls caused by this is eliminated. Further, since a plurality of pachinko ball flow channels are formed on the moving surface and the pachinko balls flow through these channels, even if a foreign substance is present on one flow channel and a ball is clogged, it will not flow to another flow channel. Has no effect. In the case of a fan-shaped clog that spreads in the conventional manner, it is difficult to eliminate the clog due to the bridge action, but when clogs occur in a line in the flow path direction, the pachinko balls discharged one after another Clogging is easily eliminated by the pushing force.

In this case, by using a metal plate as the lattice through-hole surface forming member, it is possible to maintain the abrasion property for a long period of time with less wear. Further, by providing the step in the middle, it is possible to eliminate the clogging of the balls due to the impact due to the drop, and to forcibly drop the dust and dirt.
