Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a ball passage provided inside the mechanism of a pachinko machine, for example, a prize ball guideway for guiding a prize ball to a prize ball device, or a ball for collecting prize balls. The present invention relates to a prevention device for preventing a ball from getting stuck due to the concentration of balls in the middle of a winning ball guide path from the gathering to the winning ball detection device.

[Conventional technology and its problems] There is a problem of ball clogging as one of the causes of malfunction and failure of pachinko machines. A large number of balls are constantly sent to the prize ball guide path that sends prize balls to the prize ball device and the prize ball guide path that collects prize balls and sends them to the prize ball detection device. There is.

Generally, these ball passages are constructed so that the entrances of the passages are gradually narrowed so that the balls are lined up in a row in order to avoid clogging of the balls. By the way, an even weight is supported on the upper part of the passage in a swingable manner, and balls that overlap and enter the passage are scraped off and aligned in a line. However, it is difficult to completely avoid ball clogging at the part where the width of two balls can pass in the middle of the passage to the passage of one ball, and at the meandering turn-back part. Such problems still remain.

The present invention has been devised for the purpose of eliminating the ball clogging inside the ball passage in such a pachinko machine, and in particular, it is a preventive device that reliably and effectively avoids the ball clogging at locations where the balls are concentrated. To provide.

[Means for Solving Problems] In order to solve the above-mentioned conventional problems, the present invention provides a prize ball guideway from a prize ball storage tank to a prize ball device and a prize ball detection device to a prize ball detection device. A non-round cross-section that is rotated by a motor at a ball-clogged portion such as a narrowed portion or a meandering turn-up portion where the ball-passage width is prone to occur It is intended to provide a ball clogging prevention device in which the rotation axis of the ball is exposed, and the rotation of the rotation axis collapses the overlapping of the balls to assist the alignment.

The rotation axis may be placed horizontally across the sphere passage from the bottom surface of the passage at a height position that does not obstruct passage of the sphere so as to be orthogonal to the downflow direction. The part may be cut in the lengthwise direction to form a D-shaped cross section or a polygonal cross-sectional shape. In short, if the structure is such that the overlapping spheres are impacted by rotation, the selection of the cross-sectional shape is arbitrary.

The rotation of the rotating shaft may be performed by rotating the motor in conjunction with turning on the power switch that enables the use of the pachinko machine, or by rotating the ball launching device. Since the clogged state often occurs mainly before and after the operation of discharging the prize ball, the power supply of the drive motor is connected to the display circuit such as an indicator lamp for indicating that the prize ball is present. It is recommended that the display circuit be set to rotate during the required time while it is being converted to ON or after being converted to ON. In particular, ball clogging does not occur frequently, and in the ball clogging state, if a reliable impact is given, continuous impact is not required, so it is possible to sufficiently eliminate the ball clogging by a short rotation operation. In addition, it is preferable to operate only when necessary from the viewpoint of protection of parts and power saving.

The rotation of the rotary shaft needs to be in a direction opposite to the downward direction of the balls, that is, in the direction opposite to the feeding direction, whereby the overlapping balls can be scraped.

[Operation] The ball clogging prevention device of the present invention is configured as described above, and when the balls are overlapped in a double or triple manner due to the concentration of the balls in the ball passage, a so-called bridging phenomenon occurs, and when the balls are stuck to each other, they are located above them. The rotating axis of rotation makes contact with the overlapping spheres, and the impact of the collapsing can be given to the rotating shafts, so that the butting of the overlapping spheres with each other is destroyed and the ball clogging state is eliminated.

Next, embodiments of the present invention will be described, and features thereof will be described in detail.

[Embodiment] FIG. 1 is an explanatory view showing a usage state of a ball clogging prevention device according to the present invention, FIG. 2 is an enlarged view of a main part implemented in a prize ball guideway, and FIG. 3 is an upper view. It is a III-III sectional view taken on the line.

The explanatory view of FIG. 1 shows the mechanism section 2 of the pachinko machine 1 viewed from the back side, 3 is a prize ball storage tank, 4 is a prize ball guideway, 5
Is a prize ball device, 6 is a prize ball discharge gutter for guiding the prize ball to the prize ball plate provided on the front of the gaming machine, and 7 is a ball for extracting the ball supplied to the pachinko machine at the end of the game. It is a gutter.

As is known, the pachinko machine is replenished with a predetermined number of prize balls through a replenishing device, stored in the storage tank 3, and then introduced into the prize ball device through the guideway 4. In the process of leading from the storage tank 3 to the prize ball device 5, it is necessary to arrange the balls in one row or two rows, so that the ball passage is formed to have a width through which one ball can pass gradually.

Similarly, in order to accurately supply a constant number to the prize ball device, the guide path 4 is formed to have a width capable of passing each of the two passages, and receives the flow from the storage tank 3 to further form a line. To align them, one end on the storage tank side is formed deep to prevent overflow.

In the figure, reference numeral 8 is a rotary shaft which is provided laterally in the middle of the prize ball guide path 4 formed to have such a width that one ball can gradually pass therethrough, and 9 is a motor provided for rotating this rotary shaft.

As shown in the figure, the rotary shaft 8 is laterally installed through both sides 10 and 10 of the taxiway 4 and through holes 12 that laterally pass through the wall 11, and one ball easily passes from the bottom 4a of each taxiway. Equipped to the height that can be.

The rotary shaft 8 shown here uses the output shaft of the motor 9 as it is, and a part of the peripheral surface of this rotary shaft is cut in the longitudinal direction to form a D-shaped cross section to form a non-round cross section. is there.

The motor 9 basically uses the power supplied to the pachinko machine as a power source, but even if it is connected to the input circuit that enables the pachinko machine to start, it is also connected to the power circuit of the motor that activates the ball striking device. Connected to the circuit of the display device so that it will be activated when the game starts and the prize lamp is detected and the indicator lamp that indicates that the prize ball device is activated lights up. You may.

In the present embodiment, the normal ball clogging state does not always occur, especially that occurs when the pachinko ball moves in the ball passage such as the prize ball, and the ball clogging state at the time of occurrence. If a reliable shock is given, in consideration of no need for a joint shock, wear of the device, and power saving, a prize display device, especially a prize lamp indicating that the player has won a prize ( The motor 9 was connected in the lighting circuit (not shown).

With the above configuration, when the balls flowing through the storage tank 3 into the prize ball guide path 4 connected therebelow overlap with each other in the vertical direction and repel each other in narrow passages, the ball is temporarily blocked. Although the flow will be stagnant, when the prize ball lamp lights up due to the entry of the prize ball, the motor 9 is driven by the energization accompanying this lighting, and the rotating shaft 8
As the ball rotates, the ball that has clogged the ball is impacted, and the ball-to-ball relationship is broken and the ball clogged state is broken. In this case, it is effective that the impact due to the rotation axis can be directly applied to the spheres that make up the cause of the ball clogging, but even if they do not come into direct contact with this ball, the impact on the nearby ball that caused the ball clogging is effective. If given, the impact can be transmitted to break the ball clogging state and restore the flow.

By the way, the ball clogging in the prize ball guide path 4 has been described above, but this ball clogging also occurs in the middle of the prize guide path 13 when a large number of prize balls are concentrated.

In particular, the ball clogging of the winning balls is likely to occur in the entrance portion 15 that enters the winning guideway 13 from the ball gathering (room) 14 of the winning balls.

FIGS. 4 and 5 show an embodiment of the device of the present invention at the inlet portion 15. FIG. 4 shows that the rotary shaft 8 is rotated below the turn-back opening 15a of the inlet portion which enters the guideway 13 from the ball gathering 14. FIG. 5 shows a case where the rotary shaft 8 is horizontally installed at the tip of the turn-back opening 15a.

Although not shown, the rotary shaft 8 is rotated by a motor,
The motor is connected to the circuit of the winning lamp as in the above description so as to rotate and drive with the winning display.

In any of these embodiments, the rotating shaft 8 is rotated in a direction opposite to the downward direction of the balls so that the rotating shafts 8 are overlapped with each other, or the spheres of the spheres that are engaged with each other due to the collision are more strongly engaged with each other. It goes without saying that it should not be done.

In addition, although the rotary shaft 8 has a D-shaped cross section in each embodiment, it may have a polygonal cross section or a non-round cross section such as a rhombic or elliptical cross section. it can. Further, in the embodiment, the passage is traversed, but if the rotating shaft comes into contact with a ball overlapping in the passage, it is possible to give a shock to break the ball clogging, so the protruding length up to the middle Not to mention the good news.

[Effects of the Invention] The features of the present invention have been described in detail based on the illustrated embodiment. However, the present invention effectively prevents the ball clogging by rotating the rotary shaft inserted in the ball passage. At the same time, there is an advantage that it can be easily implemented because the structure is such that the rotary shaft is provided laterally with respect to the spherical passage and the structure is such that the motor is connected to the rotary shaft to give rotation.

In addition, since the present invention can eliminate ball clogging by operating for a required time by connecting the power supply of the motor to the power supply circuit of the winning display device, it is efficient and economically advantageous.
