Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a ball flow down gutter in which multiple rows of balls are arranged in one row vertically and in rows left and right, and a protrusion is provided on one side wall of the part where each ball flows down in a row. A ball alignment structure for a ball flow down gutter in which balls that are stacked vertically and try to flow down are broken and aligned step by step by forming a recess corresponding to the protrusion in the other side wall. It is related to.

The ball flow gutter, which aligns multiple rows of balls in a single line,
Many of them have been manufactured and used in the past, but the width of the gently downwardly sloping flow path becomes gradually narrower toward the downstream, and the width at the bottom of the slope is slightly wider than the diameter of the sphere. However, in this type of system where the width of the ball flow path is gradually narrowed and the balls themselves are aligned in the process of flowing down, the length and inclination angle of the flow path are greatly related to the alignment effect, so there are dimensional and There were many restrictions on the mounting surface, which made it inconvenient to use.

In addition, the alignment effect changes depending on the cleanliness of the nine balls, vibration, etc., so it has been difficult to create a flow gutter with stable flow performance.

Therefore, with the aim of improving the above-mentioned weaknesses, the present invention provides a ball alignment structure in the part of the ball flow down gutter where the ball flows down in one line, so that even if the flow is aligned from multiple rows to one line during the flow down process of the ball flow down gutter. ＼Nevertheless, the speed that overlaps the upper and lower stages promotes the descending ball.

It is designed so that it can be discharged as a flow in one row from top to bottom and from left to right.

When the balls overlap one above the other 1. Normally, the upper ball overlaps the hollow side where the lower ball touches, and the weight of the ball acts as a force that tries to get between the lower balls, so the force 11 of the ball When the flow speed is high, when the flow starts and stops repeatedly, or due to vibration, etc., the upper ball overruns and the centers of the upper and lower balls overlap on the vertical line (the centers of the upper and lower balls overlap on the vertical line). This often occurs when the ball in the upper row is placed on top of the ball, and the gravity of the ball in the upper row no longer acts as a descending force, so it may flow down and cause a ball jam. Therefore, in order to promote the step-down action by shifting the weight of the ball left and right or front and back, a single master row structure is provided at the lower part of the single row flow of the original downspout. The master row structure is: - By providing a protrusion on one side wall of the lower part of the row and forming a groove corresponding to the protrusion on the other opposing side wall, the connection between the lower ball and the upper ball is achieved. Forcibly shifting the positional relationship of the weights to the left and right, and changing the descending velocity of the balls in the lower tier by bending in the descending direction, causing a back-and-forth shift in the flow direction as well. It was made so that it could be done.

Hereinafter, an explanation will be given of an embodiment of the present invention in which the present invention is used as a downstream gutter for supplying balls to each pachinko machine from a supply gutter provided above the pachinko machine group.

As shown in Fig. 1, a plurality of 73 drumstick machines/... are installed in parallel, and ball rental machines/... are installed at appropriate intervals between the pachinko machines/, /.
A supply gutter for pachinko balls is arranged above the pachinko machine row 3, which is made up of..., and each pachinko machine/,
Notify the nuclide S for each ball rental machine.

Each nuclide S is supplied to a pachinko machine/ball rental machine λ by arranging the pachinko balls in a supply gutter in a line, and as shown in Figs. 1 facing below the ball drop opening of
The width gradually becomes narrower toward the downstream side. In order to gradually narrow the width of the channel B toward the bottom of the slope, it is necessary to gradually narrow the width of the bottom surface 7 and make the width at the lower end of the slope slightly larger than the diameter of the ball. In order to facilitate the flow in a single line during the process, one side wall inner surface 5α is made almost vertical from the upstream side to the downstream side, and the other side wall inner surface GH is made to gradually rise from a gentle slope on the upstream side and becomes almost vertical on the downstream side. Form it like this.

Therefore, the above-mentioned nuclide j is caused by a large number of balls falling from the ball drop opening q' of the replenishment gutter to the upper end of the slope, flowing due to the slope of the bottom surface 7, forming a line by the left and right side walls ga, H, and connecting to the lower end of the slope. Although some curved gutters can be made to flow in.

Depending on the cleanliness and contamination of the bulb, the angle of inclination of the lower gutter for each bulb, vibration during use, etc., even if the nuclide S flows in a straight line until it reaches the lower end of the inclination, the upward There may be cases where the water flows down from the bottom layer.

In such a case, the balls in the upper and lower stages can be arranged in one stage by using a nine-board row structure installed in the bent gutter 9.

As shown in FIG. 8, the bent gutter 9 includes a downward L-shaped frame ta which has a U-shaped cross section and is bent downward from the force 1 midway through its length, and a frame 9α. A side plate that closes off one side opening? Consisting of b and frame? A and a side plate 9b form a downward cursor-shaped flow path 10. The inlet // of the flow path 10 has a height slightly higher than twice the diameter of the sphere and a width approximately equal to the diameter of the sphere. In addition, an upper edge part /2 is provided at the upper part of the inlet l/ that extends obliquely upward, and the inclined lower end of the upper part saw and the upper wall of the frame body α are continuous, and the height with the bottom part /3 is From the entrance //, the force gradually decreases to λ, drawing a curve, and at the exit /7, the sphere diameter υ becomes slightly wider.

Therefore, 1. When flowing into the entrance l/ of the bent gutter in the normal upper and lower stage state (the state where the upper ball is placed on the mold side where the balls are in contact), the upper ball is always subjected to the descending action of gravity. Moreover, since it receives pressure from the curved part of the upper wall of the frame body α as it flows downward, it descends into a single stage.
As shown in the figure, if the centers of the upper and lower spheres overlap on the vertical line, the water flows into the bent gutter.

Not only does the ball itself have no descending action, but when it is pressed by the upper wall of the frame 9α, a bridging phenomenon occurs, causing a ball blockage, and the majority of ball blockages in the one-ball flow down gutter occur in this state. It is. Therefore, in the original flow down trough of the present invention, the overlapping state of the balls in the upper and lower stages is forcibly shifted from side to side or front to back by using the master row structure, thereby causing the balls in the upper stage to descend.

In the above-described master row structure, a protrusion /qf is provided on the inner surface of the side wall on one side constituting the left and right walls of the channel 10, and a protrusion /l is provided on the inner surface of the other side wall opposite to the protrusion /q. In the illustrated embodiment, a protrusion /lI is provided on the side plate 9h, and a recess /&l is formed on the side wall of the frame 9α.

The protruding part /l bends the flow direction of the lower ball rolling along the bottom part /3, changes the flow speed by bending, and guides the lower ball to the recessed part /&. In the embodiment shown in FIGS. 8 to 11, the surface is approximately elliptical, and the upper surface slopes downward. Note that this protruding portion /4' may be formed by protruding a part of the metal side plate 9h, or may be fixed to the side plate q/H after being molded from a five-component resin material or the like.

The recessed part /S is a relief part that allows the lower ball whose flow direction has been bent by the protruding part /D to flow down smoothly, and the recessed part /S is a relief part that allows the ball to flow down smoothly, and the ball between the inner surface of the recessed part /j and the surface of the raised part 77. The distance should be such that only one can pass through.

Further, above this recessed part/S, at a height position of the upper stage sphere, there is a guiding support part 16 facing inside the flow path 10.
It is formed. This guide support part/6 is in contact with the side of the upper ball, and guides the upper ball in the downward direction so as not to change the flow direction when the lower ball changes its course. The distance between them is such that only one ball can pass through. Note that the length of the guide support part /6 is approximately the same as the length of the protrusion part /6, and the downstream end thereof is located near the bending part IO of the flow path IO. F1 In the master array structure formed as described above, as shown in FIG. The positional relationship with A can be forcibly shifted left and right with respect to the flow direction. Like this,
When the vertically overlapping balls A and B are displaced left and right, the upper ball B
Due to their own weight and vibration, the balls break into the gap between the lower balls A, and as they pass through the master row structure, the upper balls are promoted to descend and are aligned in one row.

Therefore, even if the spheres flowing into the bent part from the nuclide S are stacked vertically, they flow down the bent gutter, aligning the upper and lower weights into one layer and connecting them to the outlet /7. The liquid flows in a line into the flexible pipe 1g.

As shown in FIG. 1, the flexible pipe tg has its downstream end connected directly to the ball lending machine, or connected to the pachinko machine via a ball replenishment counter/9 in the middle. Therefore, when there is a shortage of balls inside the pachinko machine, the balls flow into the ball rental machine in a line through the flexible pipe, and when there is a shortage of balls inside the pachinko machine, a command from the management room is issued. Alternatively, the ball replenishment counter/9 is activated by a command from a ball shortage detector (not shown), and a predetermined number of balls are delivered to the pachinko machine/
The ball flows down to a ball reservoir (not shown) provided above the back surface of the ball.

Note that the protruding portion /4' is not limited to the above-mentioned shape, and may have any configuration as long as it can change the direction of flow of the lower sphere. For example, in another embodiment of the protruding portion /l shown in FIGS. 13 to 15, the surface for guiding one ball is an inclined circular arc surface. In addition, another embodiment of the protruding portion /4' shown in FIGS. 16 to 18 has a height of 1 which is sufficient to guide only the lower ball A to the inner surface of the side plate 9h. For example, it is installed at the same height as the center of ball A. In other embodiments shown in FIGS. 13 to 18, depressions /S may be formed on the inner surface of the frame tα in correspondence with the protrusions /G.

This is the same as in the previous embodiment. Further, in each of the above embodiments, the ball is provided in the bent gutter, but it may be provided in the gutter through which the balls aligned in one line of the one-ball flow down gutter flow.

As described above, according to the present invention, a protrusion is provided on the inner surface of one side wall so as to stand upright at the height of the lower ball flowing along the bottom surface, and a protrusion is provided on the inner surface of the other side wall opposite to the protrusion. Since a recess corresponding to the protruding part is formed, the protruding part can be used to force the positional relationship between the nuclear sphere and the upper sphere to shift left and right by changing the flow direction of the lower sphere. Without.

The lower ball is forced to take a sudden detour by the protrusion, reducing its velocity and creating a gap between it and the previous ball.
The ball in the upper row, which overlapped the upper and lower rows and was flowing downward, began to slide in front of the ball in the lower row.

At that time, the falling balls are pushed into the gaps that are present at the same time, so the descending of the steps is further promoted, and the balls flowing down overlap with the upper and lower steps to ensure that they are aligned.

In this way, it is possible to reliably align the balls flowing downward by overlapping the upper and lower tiers, so it is possible to design the total length of each ball flow down gutter shorter than the conventional one, and it is also possible to reduce the amount of dirt caused by one ball. Not only can the inclination be larger than that of conventional ones, but also it is resistant to vibrations and other environments that cause deterioration of the alignment effect during use, so stable performance can be achieved.
