Description

[Detailed description of the device] [Industrial applications]

The present invention relates to a prize ball bending gutter of a pachinko machine connected to a prize ball aligning gutter that allows a prize ball discharged from a prize ball tank to flow down in a plurality of rows by aligning it with side walls and partition ridges.

[Prior art]

Conventionally, in a prize ball aligning gutter, in which the prize balls discharged from the prize ball tank are aligned and flowed down in a plurality of rows by the side walls and the partition ridges, the ball pressure of the prize balls is weakened and the prize balls are discharged to the prize ball discharging device. A prize ball bending gutter for guiding is connected. Then, the prize balls that flow into the prize ball bending trough are smoothly moved down the prize ball aligning gutter by making the prize balls that are vertically stacked by the ball leveling member and the like into one stage and smoothly. It is supposed to be guided inside.

[Problems to be solved by the device]

By the way, the ball leveling member is pivotally supported so as to be in contact with an award prize ball in an upper stage, which generally flows down in two stages by an urging force of a weight provided below. Although the ball smoothing is performed, sometimes the ball smoothing member sometimes overcomes the biasing force of the ball smoothing member and passes through the ball smoothing member with the prize balls in two stages. In such a case, since the entrance portion of the prize ball bending trough is formed relatively large, the prize balls in the upper and lower tiers are clogged at the entrance portion, and the prize ball is discharged to the prize ball discharging device. There was a problem that it was not supplied. The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide an entrance portion of a prize ball bending gutter even when the ball-leveling portion does not completely perform the ball-leveling action. The aim is to provide a prize ball bending gutter for a pachinko machine that does not cause a ball jam condition.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the prize ball bending trough of the pachinko machine according to the present invention forms the sidewalls of the prize ball aligning trough and the lower ends of the partition ridges at an acute angle, while the prize ball bending trough The shape of the upstream end is formed in an obtuse angle so as to receive the acute lower end, and a mounting protrusion for mounting the lower end of the tip of the prize ball alignment gutter is formed on the lower edge thereof, and the ball abuts on the upper part thereof. When a protrusion is formed and the prize ball alignment gutter is connected to the prize ball bending gutter, the interval of the entrance portion below the protrusion is set to be slightly larger than the diameter of the pachinko ball and smaller than twice the diameter, It is characterized in that the prize ball aligning gutter is arranged in two steps, that is, upper and lower prize balls that flow down are prevented from entering.

[Action]

Since the distance between the entrances of the prize ball bending troughs is slightly larger than the diameter of the pachinko balls and smaller than twice the diameter, the prize balls that flow down the prize ball alignment trough will be in two stages, up and down. Even when the prize ball bending trough is reached, only the lower prize ball flows into the prize ball bending trough, and the upper prize ball is prevented from entering at the entrance portion. For this reason, a ball clogging does not occur at the entrance of the prize ball bending trough, and the prize ball can be reliably supplied to the prize ball discharging device. In addition, the prize ball bending trough and the prize ball aligning gutter are formed so that the prize ball aligning trough and the obtuse angle formed prize ball bending trough are fitted to each other, and the prize ball bending trough is formed. Since the positioning is accurately performed by the placement protrusion formed on the lower edge of the gutter and the protrusion formed on the upper portion, the prize ball can smoothly flow down.

The prize ball alignment gutter 7 arranges the prize balls falling from the prize ball storage tank 6 in three rows so that the prize balls smoothly flow down. The prize ball bending trough 8 constitutes a main part of this embodiment, and weakens the ball pressure of the prize balls aligned and flowed down by the prize ball aligning gutter 7 to be guided to the prize ball discharging device 5. Of course, the prize ball bending trough 8 and the prize ball ejecting device 5 (to be exact, the prize ball storage cylinder 24 described later) flow down the prize balls while aligning the same inside the row aligned by the prize ball aligning gutter 7. It is what makes me. Here, the detailed configuration of the prize ball aligning gutter 7, the prize ball bending trough 8, and the prize ball ejecting device 5 will be described mainly with reference to FIGS. 1 and 2, in the middle of the prize ball aligning gutter 7. Has a ball leveling member 9 (see FIG. 3) swingably supported. The ball leveling member 9 has a built-in weight below it, and acts so that the prize ball aligning gutter 7 has two upper and lower stages so that the prize balls that flow down are one level. If the upper and lower portions are continuously arranged in two steps, the ball leveling member 9 may pass through in two steps against the biasing force of the weight. In addition, the ball leveling member 9 may be provided so as to correspond to each row aligned by the prize ball alignment gutter 7, or one ball leveling member 9 may be provided so as to correspond to all the rows. Sometimes. Further, on the side wall 10 located outside the prize ball alignment gutter 7, it is possible that the prize balls flowing down the prize ball alignment gutter 7 may flow down in two steps. In that case, the prize balls fall out. It is so high that it doesn't exist. In particular,
It is formed to have a height of about twice the diameter of a pachinko ball, but the height is slightly smaller than twice that on the downstream side. In addition, partition projections 11a and 11b are provided inside the prize ball alignment gutter 7 so that the prize balls are aligned in order. The height of the partition projections 11a and 11b is higher than that of the side wall 10. It is slightly low and is formed to have almost the same diameter as the pachinko ball. The side wall 10 and the partition ridges 11a and 11b described above
Is formed such that its lower end is inclined at an acute angle, and the upstream end of the prize ball bending trough 8 connected thereto is inclined at an obtuse angle. At the upstream end of the prize ball bending trough 8, an entrance 12 for receiving the prize balls flowing down from the prize ball alignment trough 7 is formed, and the interval "D" between the entrances 12 is slightly larger than the diameter of the pachinko ball. Is designed to be. Therefore, the protrusion 13 is formed at the upper end of the entrance 12 so as to project. Further, the shape of the inlet 12 part is formed in an obtuse shape so as to correspond to the downstream end of the prize ball alignment gutter 7 as described above, and when these are connected, the connection part is matched. A mounting protrusion 23 is provided on the lower edge of the entrance 12. By placing the lower surface of the tip of the prize ball aligning gutter 7 on the mount protrusion 23, the prize ball aligning gutter 7 and the prize ball can be arranged. Bending gutter 8
The bottom surface of the is flush with the prize balls. Further, since the downstream side height of the side wall 10 of the prize ball aligning gutter 7 is formed to be substantially the same as the height "D" of the inlet 12, the tip portion of the prize ball aligning gutter 7 has a projection 13. It is stored so that it is sandwiched between the mounting protrusion 23 and
The positioning is accurately performed, and the prize balls can be connected so as to smoothly flow down. Further, the downstream side of the bent portion 14 of the prize ball bending trough 8 is formed so as to be inclined in an oblique direction, but a part of the bottom surface thereof is cut out so that the ball drop valve 15 is swingably supported. ing.
The ball drop valve 15 is an operation lever operated by an operation pin (not shown) inserted from the front of the pachinko machine 1.
It is driven by the operation of 17, specifically,
The prize ball is fixed by fixing the ball drop valve 15 in a state in which the engagement portion 18a of the operation lever 18 that engages with the operation lever 17 and the engagement portion 15a formed at the lower end of the ball drop valve 15 are engaged with each other. By guiding the discharging device 5 and operating lever 17 to rotate actuating lever 18 to disengage engagement portions 15a, 18a, ball drop valve 15 is rotated by the ball pressure of the prize ball. From the notch, it is guided to the ball drop passage 16 and discharged to the outside of the pachinko machine 1. The operation lever 17 is always urged forward by the spring 19, and therefore the operation lever 18 is also urged to the upwardly raised position. Therefore, when the engagement with the engaging portions 18a, 15a is once released and the pressing of the operation lever 17 is stopped, the engaging portion of the ball drop valve 15 is
15a is the operating lever 18 when all prize balls are ejected.
Since it is in contact with the upper position of the engaging portion 18a of the above, in order to engage the ball pulling valve 15 and the operating lever 18 again, the operation lever 17 is pressed again and the ball pulling valve 15 is operated. 15
Needs to be rotated by its own weight to engage the respective engaging portions 15a and 18a. Further, the downstream side of the prize ball bending gutter 8 constitutes a vertical passage portion 20 for guiding the prize ball in a substantially vertical shape, and a part of the downstream side of the vertical passage portion 20 has an inverted “U” shape. It is bent slightly like this. A ball shortage detection plate 21 is swingably provided so as to form the other side wall of the bent portion of the upper portion. This ball shortage detection plate 21 allows the prize balls to pass through the vertical passage portion 20.
When it disappears, the slide plate 22 connected to the lower end of the swing plate is slid outward, and the prize ball discharging device 5
The operation of the prize ball discharging device 5 is stopped by bringing the slide ball 28 into contact with the upper end of the slide plate 28, which will be described later. Further, the prize ball discharging device 5 is connected to the downstream side of the prize ball bending trough 8 as described above. To briefly describe this configuration, the prize ball discharging device 5 stores a predetermined number of prize balls. A prize ball storage cylinder 24, an upper valve 25 and a lower valve 26 located above and below the prize ball storage cylinder 24 to open and close an inlet and an outlet thereof, and a slide for alternately operating the upper valve 25 and the lower valve 26. It comprises an operating plate 28, an operating lever 29 for moving the slide operating plate 28 up and down, and a connecting rod 30 for connecting the operating lever 29 and the winning ball processing device 4. The prize ball storage cylinders 24 are arranged in a plurality of rows (3 in this embodiment).
The number of prize balls formed in a plurality of rows is regulated by a stopper protrusion 27 protruding from the lower valve 26. In the illustrated embodiment, the prize ball aligning gutter 7, the prize ball bending trough 8, and the prize ball storing cylinder 24 are shown in three rows, but the number of discharged prize balls is two ( For example, 13
1 and 7), so
In order to correspond to the number of kinds of prize balls, two rows may be arranged. Although the prize ball bending trough 8 according to the embodiment has been described above, according to this embodiment, the entrance 12 of the prize ball bending trough 8 is described.
Since the interval "D" is formed to be slightly larger than the diameter of the pachinko balls, even if the prize balls flowing down the prize ball alignment gutter 7 reach the prize ball bending trough 8 in two steps. Only the prize balls in the lower stage flow into the prize ball bending trough 7, and the prize balls in the upper stage are prevented from entering at the entrance 12 part. For this reason, a ball jam is not generated at the entrance 12 of the prize ball bending trough 8, and the prize ball can be reliably supplied to the prize ball discharging device 5. Further, since the downstream side height of the side wall 10 of the prize ball alignment gutter 7 is formed to be substantially the same as the height "D" of the entrance 12, the tip portion of the prize ball alignment gutter 7 is a prize ball. It is housed so as to be sandwiched between the projection 13 formed at the upstream end of the bending trough 8 and the mounting projection 23, and its positioning is accurately performed, so that the prize ball can be smoothly flowed down and connected. You can

[Effect of device]

As is apparent from the above description, in the prize ball bending trough of the pachinko machine according to the present invention, the distance between the entrances of the prize ball bending trough is slightly larger than the diameter of the pachinko balls and smaller than twice the diameter. Even if the prize balls flowing down the prize ball alignment gutter reach the prize ball bending trough in two steps, only the prize balls in the lower row flow into the prize ball bending trough and the upper row. The prize ball is blocked at the entrance. For this reason, a ball clogging does not occur at the entrance of the prize ball bending trough, and the prize ball can be reliably supplied to the prize ball discharging device. In addition, the prize ball bending trough and the prize ball aligning gutter are formed so that the prize ball aligning trough and the obtuse angle formed prize ball bending trough are fitted to each other, and the prize ball bending trough is formed. Since the positioning is accurately performed by the placement protrusion formed on the lower edge of the gutter and the protrusion formed on the upper portion, the prize ball can smoothly flow down.
