DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko ball replenishing gutter capable of replenishing pachinko balls in a row in a pachinko machine.

[0002]

2. Description of the Related Art Conventionally, a replenishing gutter is disposed at a downward slope above a pachinko machine, one end of which is connected to a lift via a replenishing tank, and the other end of which is mounted outside a side wall of a replenishing passage. It is connected to the ball storage tank of the pachinko machine via a supply chute. The pachinko balls flow from the supply tank through the supply gutter, drop from the inlet of the supply chute, pass through the supply chute in the direction opposite to the direction of travel of the pachinko balls flowing through the supply path, and flow into the ball storage tank from the discharge port. I do. By the way, as a problem of the conventional supply gutter (supply chute), a so-called bridge phenomenon in which pachinko balls flowing into the entrance of the supply chute are overlapped and clogged at the entrance has occurred. The principle of the occurrence of the bridge phenomenon will be described with reference to FIG. The direction in which the pachinko balls 13A flowing into the supply chute 12 from the supply path 11a of the supply gutter 11 and the pachinko balls 13B that have already flowed do not match (FIG. 6).
a), the supply gutter wall cut surface 12c, the flowing pachinko balls 13A, and the flowing pachinko balls 13B are arranged in an arc shape as shown in FIG. 6B, causing a bridging phenomenon. As a solution to this problem, there is an example in which a rocking body is attached to an inlet of a replenishing chute as a means for dividing an arc constituting a bridge and for giving instability to the bridge. An example is a pachinko ball alignment gutter disclosed in Japanese Patent Application Laid-Open No. 5-300964. According to this conventional example, as shown in FIG. 7, an oscillating body 27 centered on a horizontal shaft 26 constituting a movable portion provided at an eccentric position at an inlet portion of a supply chute 22 connected outside the side wall of the supply gutter. And a weight 28 is attached to the oscillating body at an eccentric position opposite to the horizontal axis, and the pachinko balls 23, which are overlapped in two stages, abut against the oscillating body to prevent the pachinko balls 23 from moving forward, thereby causing a bridging phenomenon. To prevent pachinko balls from being discharged from the discharge port of the supply chute in an orderly manner.

[0003]

In this conventional example, although the effect of suppressing the bridging phenomenon is exhibited, when the oscillating body loses smooth movement, the directions of the arrows shown in FIG. Therefore, there still remains a problem that it is difficult to maintain the performance because of the movable portion 26. SUMMARY OF THE INVENTION An object of the present invention is to make it possible to maintain the performance of preventing the bridging phenomenon over a long period of time and to manufacture the device at a low cost with a simple configuration.

[0004]

In the supply gutter of the present invention, a supply chute for supplying pachinko balls to each pachinko machine from the supply path is connected to a lower portion of the supply path having a downward slope. The chute has a slope in the same direction as the downward slope of the supply path, the lower end serves as a discharge port for pachinko balls, and the upper end serves as an inlet communicating with the bottom surface of the supply path. The ball introduction part and the partition are arranged side by side along the side wall of the supply path. The inlet is opened at the bottom of the supply path, the partition wall is arranged on one side, and one side wall of the supply path is located on the other side. The pachinko ball introduction portion allows a pachinko ball traveling on the supply path to flow into the entrance from the side of the entrance. The partition is raised from the bottom of the supply path, and the height of the partition is gradually increased from one end to the other end in the traveling direction of the pachinko ball. It gradually rises toward the edge. At one side of the entrance, one end of the partition wall is adjacent to the introduction portion of the pachinko ball on the side opposite to the traveling direction of the pachinko ball (upstream side of the supply path), and the other end of the partition wall extends to the other end of the entrance. I have. The partition has a function of preventing a part of a pachinko ball from flowing into the entrance from the side of the entrance. In the partition wall, the upper end shape may be formed in an arc shape in which a lower portion is a concave portion, or may be a linearly inclined shape.

[0005]

[Function] The supply chute is inclined in the same direction as the downward slope of the supply path, and the entrance of the supply chute is opened at the bottom of the supply path, so that the traveling directions of the pachinko balls flowing through the supply path and the supply chute are in the same direction. As a result, the occurrence of a bridge phenomenon caused by a mismatch in directionality is suppressed.
By adopting a configuration in which the height of the bulkhead gradually increases in the same direction as the downward slope of the supply path, the pachinko balls smoothly flow into the inlet of the supply chute and do not obstruct the path of the pachinko balls that have flowed in, and the bridge The occurrence of the phenomenon is prevented. The pachinko ball introduction portion is provided adjacent to the partition wall, and one end of the partition wall gradually rises from the bottom of the supply path toward the other end, so that the pachinko ball smoothly flows into the entrance of the pachinko ball.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the present invention, a pachinko ball 3 is provided to each pachinko machine from a lower part of a supply path 1a of a supply gutter 1 having a downward slope as shown in FIGS. The supply chute 2 for replenishment is connected, but in order to suppress the bridging phenomenon, the supply chute is first inclined in the same direction as the downward gradient of the supply path, and the pachinko machine which flows through the supply path and the supply chute respectively is used. The traveling direction of the ball is the same direction (the right direction in FIG. 1). The lower end of the supply chute 2 is a discharge port 2a for pachinko balls, and the upper end is an entrance 2b communicating with the bottom 1a1 of the supply path. This entrance is opened in the bottom 1a1 of the supply path in an appropriate shape such as a rectangle. Therefore, the pachinko balls 3 flowing through the supply path flow into the supply chute from the bottom without largely changing the direction. Further, the inlet 2b of the supply chute 2 has a pachinko ball introducing portion 4 and a partition wall 4 on one side (upper side in FIG. 2) along the side wall 1b of the supply path 1a. The pachinko ball introduction portion 4 is for enabling the pachinko balls 3 traveling on the supply path 1a to flow into the entrance from the side of the entrance 2b. The partition wall 5 is located on one side of the inlet 2b, and one side wall 1b of the supply path 1a is located on the other side. The bulkhead 5 is the bottom 1 of the supply path
a1. One end of the partition wall 5 is opposite to the pachinko ball introduction section 4 and the side of the pachinko ball traveling direction (supply path 1).
a) on the left side of FIGS. 1 and 2,
The other end of the partition extends to the end of the entrance. This partition,
Among the pachinko balls 3 traveling on the supply path 1a, the pachinko balls 3 have a function of preventing the pachinko balls from flowing into the inlet 2b from the side. However, since all of the pachinko balls flowing from the side do not obstruct the path of the pachinko balls flowing into the replenishment chute 2, the partition wall 5 has one end as shown in FIGS. The configuration is such that it gradually increases in the direction of travel of the pachinko ball starting from the supply path bottom surface 1a1 toward the end, so that only obstacles can be prevented. In the example shown in the drawing, the partition line 5 is formed in an arc shape in which the lower end is a concave portion, but a straight line that is higher in the traveling direction is formed from the upper end shape, that is, the line connecting the highest end to the lower end 1a1. It may be made into an inclined shape.

Next, the operation of the present invention will be described with reference to FIGS. 1, 2 and 5. The pachinko balls 3 in the supply path 1a of the supply gutter 1 flow in the direction of the arrow in FIG.
The pachinko balls 3A that have flowed in from the same direction do not interfere with the pachinko balls 3B that have already flowed because they flow in the same direction. The height of the partition wall 5 is gradually increased from one end side toward the advancing direction with respect to the pachinko ball 3C which is about to be interrupted from slightly in front of the flowing pachinko ball 3B, so that the pachinko ball 3C is not hindered by the partition wall. Further, the partition wall 5 whose other end side (downstream side) is higher can prevent the pachinko balls 3D that obstruct the course of the pachinko balls 3B flowing into the replenishing chute 2 from interrupting, thereby preventing the occurrence of bridge reduction. To prevent.

In FIG. 4, the upper end of the partition wall 5 is formed in an arc shape over the entire length, and one end side of the partition wall 5 is flush with or substantially flush with the bottom 4a1 of the pachinko ball introducing portion 4 and the replenishment path, so that the partition wall 5 is located near the entrance 2b. While the pachinko balls can smoothly flow in from the side, the other end of the partition wall can prevent the inflow of the pachinko balls that obstruct the course of the flowing pachinko balls.

[0009]

According to the present invention, the supply chute inclined in the same direction as the gradient of the supply path is connected to the bottom of the supply path, and the pachinko ball introduction portion and the bottom of the supply chute are provided at the side of the entrance of the supply chute. A raised partition wall is provided to prevent the bridging phenomenon without providing any mechanical means such as the conventional rocking body. Therefore, the performance of preventing the bridging phenomenon from occurring can be maintained for a long period of time. , And can be manufactured at low cost.
