[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a ball alignment rail of a pachinko machine for aligning a flow of balls received from a ball tank in a single row and supplying it to a ball dispensing device.
[0002]
[Prior art]
Below the ball tank of the pachinko machine, a ball alignment rail and a ball dispensing device are arranged, and the flow of the balls supplied from the ball tank in a plurality of stages and a plurality of rows is arranged in a row and a row by the ball alignment rail. And supply it to the ball dispensing device. When the ball payout device is a double type that pays out the winning balls and the rental balls, the ball alignment rails are naturally arranged in two rows and supplied to the ball payout device. A row means a state in which balls are supplied to one row with respect to one entrance of the ball dispensing device.
[0003]
The above-described ball alignment rail has a structure in which the flow of the spheres is gradually narrowed in the middle in order to align the flow of the spheres supplied in a plurality of rows and rows. However, there is a problem in that the ball forms a bridge at the portion where the width of the ball passage is narrowed for this purpose, and the game is blocked. For this reason, a swing-type weight is widely used that suspends a swing-type weight above the throttle part of the ball alignment rail and applies resistance to the upper-stage sphere. There is a problem that the effect of leveling out is not sufficient, and it is necessary to suspend another member, so that the number of assembling steps increases and the cost increases.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a view showing the upper part of the back surface of a pachinko machine equipped with a ball alignment rail of the present invention, wherein 1 is a ball tank, 2 is a ball alignment rail of the present invention disposed below the ball tank, and 3 is a ball deceleration passage. In addition, a double ball dispenser (not shown) is disposed at the tip of the ball deceleration passage 3. The sphere tank 1 sends the spheres from the sphere supply port 4 at the end to the lower sphere alignment rail 2 in a plurality of rows and rows.
[0009]
2 to 5 are views showing the ball alignment rail 2 of the present invention. The ball alignment rail 2 is formed by mounting the upstream side press plate 6 and the downstream side press plate 7 on the ball alignment rail body 5. . The ball alignment rail body 5 is formed in a bilaterally symmetric shape via a central partition 8 so as to correspond to a double ball dispenser, and only one side will be described below.
[0010]
The ball alignment rail body 5 includes an upstream alignment portion 11 (upstream of the ball alignment rail) that aligns the balls introduced from the ball tank 1 in a plurality of stages in a plurality of rows, and a sphere that has flowed in a plurality of stages. It is roughly divided into a downstream side alignment section 12 (downstream side of the sphere alignment rail) that aligns the flow in one stage. Reference numeral 13 denotes a mainstream ball train guide which is a spherical passage provided by communicating the upstream alignment portion 11 and the downstream alignment portion 12. The mainstream ball train guide 13 aligns the lowermost ball train on a line. The guide groove 14 to hold, the side wall 15 which guides so that a spherical row may not deviate, and the side wall 16 which is the center partition 8 are provided.
[0011]
As shown in FIGS. 3 and 6, the upstream side alignment portion 11 is formed in a width that can accommodate two rows of mainstream and substream spheres, and a guide side wall 17 of the substream spheres is formed on the outside. It is connected to the side wall 15 of the mainstream ball train guide 13 on the downstream side. Further, the bottom surface 18 of the secondary flow ball row is inclined to the main flow side, and is inclined to be higher than the main flow ball row on the downstream side as shown in FIG. For this reason, the spheres on the bottom surface 18 of the secondary flow ball row naturally flow into the main flow side as they move downstream, and are aligned in a single row as shown in FIG. As shown in FIG. 8, the number of spheres introduced in a stacked manner is only reduced to two in the upstream side alignment portion 11. Therefore, the spheres usually flow into the downstream side alignment section 12 in two stages and one row, but sometimes the rolling resistance of the sphere fluctuates and flows in three stages, and is always reduced to two stages. It does not necessarily flow in.
[0012]
As shown in FIGS. 6 and 7, the side wall 21 on the main flow side of the side flow ball row connected to the bottom surface 18 of the side flow ball row is deflected in a direction away from the main flow side. On the other hand, the guide side wall 17 on the outer side of the sidestream ball train is bent from the vicinity of the deflection point until it coincides with the mainstream side wall 15 toward the mainstream side to form a widened portion 22 that is curved as a whole. is doing.
[0013]
An upstream presser plate 6 and a downstream presser plate 7 are connected to the upper part of the mainstream ball train guide 13 downstream of the entrance of the widened portion 22 as shown in FIGS. On the back surface of the upstream holding plate 6, a spherical deflection projection piece 23 having a rhombus cross section is provided so as to be in contact with only the second or higher sphere. For this reason, the second and higher spheres are deflected by the sphere deflecting projections 23 along the widened portion 22 and flow downstream along a path curved in a dogleg shape. For this reason, the flow resistance is added to the upper sphere more than the lower sphere. As a result, as shown in FIG. 8, the upper sphere is delayed from the lower sphere, and the number of spheres is reduced. However, in this state, the spheres flowing in the second stage are not always stably reduced to the first stage.
[0014]
Therefore, the uppermost presser plate 6 and the downstream presser plate 7 push down the uppermost ball flowing in a stacked state as it flows down to interrupt the lower ball, thereby reducing the number of steps of the ball. That is, as shown in FIG. 9, the height of the upstream end of the upstream holding plate 6 is such that the sphere formed in three stages can pass through to prevent clogging of the sphere due to the formation of a bridge or the like. On the other hand, the height of the downstream end of the upstream presser plate 6 is such that a two-stage sphere can pass through. Therefore, even if the spheres flow in in a three-stage state, the number of spheres flowing out from the upstream holding plate 6 can always be reduced to two or less without causing clogging.
[0015]
Further, the height of the upstream end of the downstream presser plate 7 is the same as the height of the downstream end of the upstream presser plate 6 so that a two-stage sphere can pass through, while the downstream presser plate is on the other hand. The height of the downstream end of 7 is such that only one stage of the sphere can pass through. Therefore, even if the spheres flow in a two-stage state, the number of spheres flowing out from the sphere alignment rail 2 can always be supplied to the sphere dispensing device as one tier without causing a sphere clogging.
[0016]
As shown in FIG. 2 or FIG. 5, the upstream holding plate 6 has a projection (not shown) provided outside the projection piece 24 fitted in a mounting hole 29 provided in the side wall 15 and a spherical deflection. A slit formed in the projecting piece 23 is supported by the upper edge of the central partition wall 8 and attached to the ball alignment rail body 5. Further, the downstream end of the upstream presser plate 6 serves to hold the downstream presser plate in a predetermined position when the downstream presser plate 7 is inserted. A regulating piece 30 is provided at the side end, and the downstream presser plate 7 can be prevented from being lifted by the ball pressure.
[0017]
Further, the downstream pressing plate 7 is slidably inserted along the upper edge of the central partition wall 8 by guide protrusions 25 provided at the downstream ends of the side walls 15 on both sides. An elastic piece 27 having a locking claw 26 for locking the presser plate 7 at a predetermined position during use of the ball alignment rail is provided at the downstream end of the downstream presser plate 7. A stopper 28 is provided at the side end. Therefore, when an abnormal situation such as dust flowing in and clogging of the ball occurs, as shown in FIGS. 5 and 10, the elastic piece 27 is lifted to release the locking by the locking claw 26 and the downstream side presser is pressed. By pulling out the plate 7, the upper part of the mainstream ball train guide 13 is opened and the abnormal situation can be solved. Further, the stopper 28 can prevent the presser plate 7 from slipping out of the ball alignment rail body 5 when sliding.
[0018]
Although the embodiment in which the presser plate is divided into the upstream presser plate 6 and the downstream presser plate 7 has been described above, the presser plate may be integrated with the upstream presser plate 6 and the downstream presser plate 7. Similar effects can be obtained. In this case, an elastic piece 27 having a locking claw 26 for locking the presser plate at a predetermined position is provided at the downstream end of the presser plate, and the presser plate is provided at the upstream end of the presser plate. It is desirable to provide a stopper that prevents the ball alignment rail from slipping out during sliding. The material of the press plate is desirably slippery with respect to the sphere, and the angle of the press plate with respect to the bottom surface of the mainstream ball train guide 13 can be appropriately adjusted between 3 and 15 ° depending on the material. For example, when the material is POM resin, it is desirable to set it to about 10 °, and when it is ABS resin, it is preferably set to about 5.5 °.
[0019]
【The invention's effect】
As described above, the ball alignment rail of the pachinko machine according to the present invention has a ball plate for leveling the ball on the downstream side of the ball passage on the downstream side of the ball alignment rail, and the upstream end of the press plate is a multi-stage ball. The downstream end of the presser plate is set to a height that allows one stage of the ball to flow out, and the downstream end is inclined downward so that the presser plate is the uppermost ball. Can be pushed down as it flows down and interrupted between the balls of the lower tier to reliably reduce the number of spheres. Therefore, the ball alignment rail of the pachinko machine according to the present invention has a great advantage that the flow of the spheres flowing in a plurality of stages can always be stably supplied to the ball dispensing device as one stage and one line.
